Austrian Patent Office AT 500 459 B1 2010-08-15
The invention relates to a method for assembling a receiving device for blood, body fluids, tissue parts or tissue cultures, wherein the receiving device by a closure device comprising a cap and a sealing device inserted therein before screwing from a pierceable, highly elastic and self-closing Material, and formed by an approximately cylindrically shaped, an interior enclosing, receptacle having an open end, wherein the joining process by a cap skirt of the cap with its open and the receptacle end facing an open end face of the receptacle is overlapped and further a sealing surface of the Sealing device is inserted into the open area of the interior of the receptacle, wherein provided between the cap and the receptacle, a thread assembly with cooperating threads and for the assembly between the closure device and the receptacle a relative pivotal movement about a common longitudinal axis is performed.
WO 98/14373 or parallel US 5,858,141 A describe various devices for placing a cap with a thread on a bottle-shaped container, which also has a thread. In a first embodiment according to the figures 1 to 5, the pre-positioned on the bottle cap is supplied together with this by means of a conveying device of a pressing station, wherein a pressure force is exerted on the cap by reducing the distance. By this pressing force, the cap is pressed without any rotational movement due to the elastic deformation and expansion of the same over the threads on the bottle neck. In the other figures 6 to 8, another embodiment of a mounting device has become known, in which the cap is detected at its outer periphery by two opposite and specially driven drive wheels. These drive wheels generate the rotational movement of the cap relative to the receptacle, whereby the cap is screwed in cooperation with the threads. It is disadvantageous that in the first mounting device, a pure pressing of the cap without any rotational movement takes place whereby no clear completely screwed position is achievable in all applications. According to the second embodiment, a high machine cost in a large footprint is necessary.
From DE 28 29 755 A1 a method for gas-tight sealing of a container and a trained cap has become known. In this case, the cap is screwed by applying a torque to a threaded container approach in a first process step. The applied torque is less than the final release torque. In a further method step, the transition region of the closure cap between the bottom and the thread is dented just enough by means of a closing punch that the shortening of the axial height of the transition region caused by this causes the thread of the closure cap to move against the flanks of the thread in one of the setting movements of the closing punch pulls on the container approach. Thus, only by placing the Verschließstempels a mutual wedging the thread to the final release torque. The Aufschraubvorgang the cap takes place here by a specially applied torque, whereby the connection between the cap and the container is created in cooperation of the thread assembly.
From US 5,687,552 A, an adapter system for screwing a cap on a container has become known, in which the aufzuschraubende cap is held in a cap holder. Between the cap holder and the spindle provided about a longitudinal axis and with a drive, an adapter element with a first and a second adapter element is additionally arranged. The first adapter element is in driving connection with the spindle applying a drive torque via a thread arrangement. The 1/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Cap holder is connected via a further threaded arrangement with the second adapter element fixed in drive connection. Between the first and second adapter element, a rotational connection fixed in the form of a wedge connection with a keyway arranged in the second adapter element and a wedge arranged in the region of the first adapter element are formed. The second adapter element is further associated with a spring element in the region of the rotatable spindle, with which the second adapter element is pressed into a position remote from the first adapter element. Due to the cooperating wedge connection, however, an axial longitudinal displacement between the first and second adapter element is possible within certain limits. For placing the cap is at the beginning, especially if it has a tamper-evident ring, a higher pressing force in the axial direction required, in which case the first and second adapter element are spent against the spring force in a closer together adjacent position. Subsequently, the necessary axial force for screwing the cap is generated by the spring force of the spring element in cooperation with the rotation of the spindle. The disadvantage here is the high mechanical complexity for generating the screw-on.
Various recording devices, which describe a receptacle and a coupling device which can be coupled thereto, have become known from EP 867 678 B1, EP 1 174 084 B1, EP 1 174 085 B1 and also US Pat. No. 6,017,317 A1. In this case, a coupling device in the form of a threaded arrangement is described between the closure device, in particular the cap, and the end of the receptacle to be closed, wherein the threaded arrangement in the region of the receptacle distributed over the circumference arranged thread segments, which are each arranged spaced apart in the circumferential direction. In the region of the inside of the cap, the sealing device composed of a plurality of layers is arranged, which comprises a resealable layer, a connecting layer arranged between the latter and a gas barrier element, and a further connecting layer between the gas barrier element and the receiving container. In addition, the resealable element is glued in the cap by means of a hot melt adhesive. In this case, the connection or holding force of the further connection position between the gas barrier element and the receptacle is less than the connection force of the arranged between the resealable element and the cap hot melt adhesive. For guiding and pre-positioning of the cap with respect to the threads on the receptacle guide projections are arranged within the cap, which are seen in the circumferential direction shorter than the gap between the individual threads. The joining process of the cap with the receptacle takes place by means of a rotary or pivoting movement, which is applied to the cap.
Other closure devices of the same Applicant have become known for example from EP 0 915 737 B1, in which the conical sealing element used in the bottom region of the receptacle and biased by means engaging in the outer periphery of the receptacle cap is so as to ensure a sufficient tightness to achieve. The coupling takes place via a pure snap action between the cap-like closure element and the receptacle.
Another closure device of the same Applicant has become known from EP 0 445 707 B1 and US 5,294,011 A, in which between the cap and the sealing element, a coupling device is arranged, which in the region of the cap by over the inner surface in the direction on the longitudinal axis protruding projections and a sealing plug protruding approach is formed. In addition, an additional retaining ring is provided between the flange-shaped approach of the sealing plug and the remote from the receptacle arranged extension of the cap. For placing or screwing the cap on the receptacle on the inside of the cap guide webs or threads are arranged, which cooperate with guide projections on the receptacle. In this case, the placement of the cap by means of a Aufschraubvorganges, caused by a relative rotational movement between the cap and the receptacle, or simply pushing the cap over the guide projections on the receptacle done. Finally, other closure devices of the same Applicant have become known from EP 0 419 490 B1, US Pat. No. 5,275,299 A, US Pat. No. 5,522,518 A and US Pat. No. 5,495,958 A. From these documents, on the one hand a coupling device between the cap and the receptacle and a further coupling device between the arranged in the cap sealing device and this is described. The coupling device between the cap and the receptacle is again formed here by guide projections in the region of the receptacle and thus engageable guide webs, such as threads, on the cap inside. In this case, the screwing-on movement takes place until the cap is applied far enough beyond the open front side of the receptacle, so that the guide extensions of the receptacle are moved in the free space between the end of the guide web or thread turn and the end wall of the cap. As a result, a free rotation of the cap relative to the receptacle is possible without engagement of the coupling device is present. Again, the placement of the cap by a Aufschraubvorgang or a sliding over the cap with the guide web arranged thereon could be done on the or the guide extensions on the receptacle again. This is possible due to the elasticity of the cap.
From EP 0 753 741 A1 a receiving device with a receptacle has become known, which has two spaced apart in a longitudinal axis ends, of which at least one is formed with an opening. The inner dimension of the receptacle in the region of the first open end in the plane aligned perpendicular to the longitudinal axis is greater than the inner dimension in the region of the further end in the plane aligned parallel thereto in the same spatial direction. Furthermore, an annular component is used in the open end, which covers the open end side of the receptacle with a collar and a cylindrical wall portion projects into the interior of the receptacle at least partially. The annular component has, following the cylindrical wall part, a shoulder and, connected thereto, a cross-sectional widening on which the elastic sealing element of the separating device is supported in the starting position. In the center, the separator has a recess which is closed with a thin cover plate in the region of the upper end of the receptacle. The joining of the individual components, in particular the onset of the separating device, takes place in a vacuum chamber, since after insertion of the separating device without damaging it, access to the interior is no longer possible. In addition, a film is still glued to the collar-shaped projection of the annular member and attached a cap. The filling of the interior is carried out by means of a puncture of the thin cover plate of the separator, the thin film and possibly the cap. Through this filling process, the vacuum is reduced in the interior, which also air is sucked into the interior. Subsequently, there is the centrifuging process, in which the separating device emerges from the annular member in the direction of the closed end and further comes with its sealing element on the inner surface of the receptacle to the plant. The rate of descent in the mixture or the already separated components is determined by the contact pressure of the elastic sealing element on the inner surface. By choosing the density of the entire separation device with respect to the components of the mixture to be separated, they float at the interface between the two different density media. A passage of the lighter medium during the centrifuging process is possible between the inner surface of the receptacle and the elastic sealing element.
Another receiving device with a separator has become known from EP 1 005 910 A2, which has a cylindrical receptacle having a nearly constant inner diameter. At the open end of the receptacle, a pierceable closure device is arranged, on which, even in the starting position, the separation device is arranged almost fitting. This separator is formed of a flexible recoverable material, wherein on the outer periphery of the separator, a sealing device is provided for sealing with the inner surface of the receptacle. In addition, a deformable element is still used in the interior, which is pressed against the inner wall of the outer container during the application of the centrifugal force by the pressure exerted by the medium and thus between the separating device and the inserted deformed insert part, a flow-through channel is formed which, after removal of the centrifugal force, again assumes a sealing position with the sealing elements arranged on the separating device, whereby the media separated from one another remain separated from one another.
It is already a receiving device for a mixture of at least two media, according to DE 195 13 453 A1, known, which has a eprouvettenartigen receptacle which is closed in an open Stirnendbereich with a closure device and in which a separation device for separating the different media of the mixture is used after separation. In order to prevent the subsequently coming into contact with a medium face of the separator is contaminated when filling the mixture into the interior of the container, the separator is provided in the central region with a through hole through which the mixture in the remaining interior of the receptacle can be introduced. During the subsequent separation process by centrifugation in a conventional manner with a radial centrifugal force (rcf) of 1,000 g to 5,000 g-g being gravity and 1 g a value of 9,81 m / s 2-the medium separated from the mixture is passed through the breakthrough in the separating device is transferred into the area located between the sealing device and the separating device and consequently decreases in the direction of the closed end of the receiving container. In order to prevent that after separation by the breakthrough, the other medium located between the closed end and the separating device can mix again with the medium separated therefrom, in one of the usual remaining amount of the other medium corresponding height is in the direction of the closed End cone-shaped widening end stop provided, with which the separator on the end stop, which penetrates through the aperture, runs up. As soon as the outer diameter of the end stop corresponds to the inner diameter of the opening, the separating device remains in this position and thereby the opening is closed with the stop and there can be no exchange or re-mixing of the two media. A disadvantage of this embodiment, that a tube must be made with an internal stop and no safe function of the medium separation, due to the arranged in the separator breakthrough, can be ensured. Furthermore, a subsequent insertion of the separator into the interior of the receptacle is difficult to implement.
Other recording devices for centrifuging mixtures to be separated from at least two different media, in which the receptacle is closed in both Stirnendbereichen with a closure device, are known from WO 96/05770 A1. Inside a separating device formed by a sealing disc is arranged, which is formed by a gel. During the centrifuging operation, this gel piston migrates due to its specific gravity, which is higher than the specific gravity of the medium of lower specific gravity and lower than the specific gravity of the higher specific gravity medium, due to the centrifugal forces acting on it between the two different, separate media. In this position positioned so that a separation of the one medium from the other medium of the mixture take place. The disadvantage here is that the storage time, due to the separation device made of gel, in many cases is not sufficient for the normal duration of use.
Further recording devices with separating devices arranged therein, which are formed with a wide variety of valve arrangements and filter elements, are known from EP 0 311 011 A2, US Pat. No. 3,897,343 A, US Pat. No. 3,897,340 A, US Pat. No. 4,202,769 A and US Pat. No. 3,897,337 A.
Other recording devices with separation devices therein are known from EP 1 106 250 A2, EP 1 106 251 A2, EP 1 106 252 A2, EP 1 106 253 A2 and EP 1 107 002 A2, wherein the separation devices in the different 4/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Embodiments are formed and based on the principle of deformability of a component of the separation device during the centrifuging and the density of votes between the media to be separated.
The present invention has for its object to provide a method for assembling a cap with one end of a receptacle, in which the assembly or joining process is simple and inexpensive in terms of the required mounting means feasible.
The object of the invention is achieved in that at the same time several closure devices are spent with the receptacles to be joined to form the receiving devices in a common mounting device, whereupon before assembly of the components to be joined, the interiors of the receptacle to a lower pressure relative to the ambient pressure are lowered, and for the joining operations one of the components to be assembled on a thrust bearing of the mounting device is rotatably supported about its longitudinal axis, wherein by the mounting device on at least one of the components to be assembled a directed approximately in the direction of the longitudinal axis compressive force (F) is applied and thereby is converted by the cooperating threads the compressive force (F) for generating the relative movement in the relative rotational or pivotal movement about the common longitudinal axis and during the relative rotational or pivotal movement the Gewindegän ge the thread assembly over the entire length of the Einschraubweges until reaching the fully screwed position engage each other.
The resulting from this combination of features advantages are that so in a single operation, a large number of recording devices can be completed, which in short cycle times a large number of assembled recording devices can be achieved. Likewise, so can be found even with a small footprint for the joint joining process Auslangen. Furthermore, it is supported in a known manner with appropriate choice of the negative pressure suction of the material to be filled into the interior, in particular blood, during the removal process. Thus, otherwise occurring friction losses are compensated and it is subsequently possible a proper filling. Thus, a tight closure device for the receptacle can be created, which can be introduced in a simple manner by a pure implementation of a rectilinear motion in a rotational movement about the receptacle. Thus, a uniform implementation of the axial compressive force is achieved in a rotary motion. Another advantage is that only by applying a directed in the direction of the longitudinal axis of the receptacle or the cap pressure force (F) in cooperation of arranged between these components of the assembly thread assembly, this axially acting pressure force (F) the relative pivoting or rotational movement between generates these components and so the screwing up or screwing is performed. As a result, otherwise necessary assembly machines, which perform the previously required for this rotation or pivoting movements can be saved. This method according to the invention leads to a reduction in costs in the field of automatic assembly machines, since only a simple longitudinal movement with corresponding application of force is to be carried out here. Furthermore, a cost reduction by the smaller footprint and by the possible with this method shorter cycle times can be achieved. In addition, however, the cost of the resulting maintenance or repairs are reduced by the simplified joining process.
Furthermore, a procedure according to the features specified in the claims 2 to 4 features advantageous because thereby the handling of the joining or assembly process of the receiving device is better and easier to perform. As a result of the predetermined holding of the closure device or the receptacle, the receptacle and / or the closure device can optionally be brought into the relative pivoting or rotational movement by the application of the predeterminable compressive force (F). In addition, but here also the closure device loosely placed on the receptacle, then the one or more receptacles fixedly supported and by subsequent Austrian Patent Office AT 500 459 B1 2010-08-15
Applying the compressive force (F) the closure device are moved in a rotational movement relative to the receptacle, whereby the joining operation is carried out and performed with appropriate selection until fully screwed. As a result, a multiple arrangement of recording devices to be screwed is possible, whereby in addition a simple and quick installation can be carried out at low machine cost.
A further advantageous procedure is described in claim 5, whereby in the interaction of the coupling device between the cap and the receptacle in the form of the threaded arrangement a definite predeterminable Aufschraubbewegung is performed. By choosing the amount of pressure and the Aufsetzgeschwindigkeit a definite definable end position between the components to be joined can be achieved.
Also advantageous is a variant of the method according to claim 6 or 7, characterized in that, depending on the coating and selected pitch angle of the meshing threads the required pressure force for assembly can be reduced or reduced, whereby a safe and rapid joining process is possible.
Furthermore, a procedure according to the features specified in the claims 8 to 11 is advantageous, since thereby the coating can be applied in dependence on the different friction conditions between the components to be joined in a selective manner and thereby depending on the application the corresponding friction values at appropriate Choice of coating can be reduced.
Finally, by an approach according to the method step according to claim 12 but also additionally the sealing behavior between the sealing plug and the receptacle can be influenced. Likewise, however, this can additionally influence the sealing behavior between the sealing plug and the receptacle.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals and the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis transferred to like parts with the same reference numerals or identical component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.
In Figs. 1 to 9, a receiving device 1 is e.g. for a mixture 2 of at least two mutually different components or media 3, 4, such as body fluids, tissue parts or tissue cultures shown.
The receiving device 1 consists of an approximately cylindrical receptacle 5 with two mutually distanced ends 6, 7, wherein in this embodiment, the end 6 is formed open and the end 7 is formed by an end wall 8 closed. The here open end 6 is closed with a closure device 9 shown in a simplified manner as needed and can for example be designed according to EP 0 445 707 B1, EP 0 419 490 B1, US 5,275,299 A, US 5,495,958 A and US 5,522,518 A, wherein In order to avoid repetition, the disclosure for the formation of the cap, the sealing device, the housing or receptacle, the coupling device between the cap and the sealing device and the cap and the cap and the AT 500 459 B1 2010-08- 15
Receiving container 5 and the arrangement of the retaining ring reference and is taken over in the subject application. In a space enclosed by the receptacle 5 interior 10 may additionally be used a separator, which is not shown here. The procedural procedure for the assembly or assembly between the closure device 9 and the receptacle 5 will be described in more detail below. This receptacle 5 with the closure device 9 may for example be designed or used as an evacuated blood sampling tube in various embodiments.
The receptacle 5, for example, bottle, vial, piston-shaped or the like. Formed and made of a variety of materials, such as plastic or glass, be formed. Is selected for the receptacle 5 as the material plastic, this may be liquid-tight, in particular waterproof and optionally gas-tight and for example of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polystyrene (PS), high-density polyethylene (PE -HD), acrylonitrile-butadiene-styrene copolymers (ABS) or the like or a combination thereof. Furthermore, the receptacle 5 has a container wall 11 with a wall thickness 12, wherein the container wall 11, starting from the one end 6 with an inner dimension 13 in a direction perpendicular to a running between the two ends 6, 7 longitudinal axis 14 level 15 out to another, arranged in the region of the end 7 and extending parallel to the first plane 16 extending further level 16 with a smaller dimension 17 extends. The container wall 11 of the receptacle 5 has an inner surface 18 facing the inner space 10 and an outer surface 18 facing away from it, which thus defines an outer circumference for the receptacle 5. Due to the inner surface of the container wall 11 with the inner clear dimension 13,17 is thus an inner cross section, which has a variety of cross-sectional shapes, such as. circular, elliptical, oval, polygonal, etc., may have. The shape of the outer cross section may also be circular, elliptical, oval, polygonal, etc., but it is also possible to make the shape of the outer cross section different from the shape of the inner cross section.
It is advantageous if the inner dimension 13 of the receptacle 5, starting from one end 6 to the distant from this further end 7 is continuously minimally reducing to the inner dimension 17 is formed, for example, the receptacle 5, if this off Plastic material is manufactured in an injection molding process, to be able to easily demold from the injection molding tool. Further, by this tapered taper between the two planes 15, 16, the extent of the decrease of the inner dimension from the larger dimension 13 to the smaller dimension 17 is predetermined. The taper or taper angle is, based on the inner opposite surfaces of the receptacle 5, between 0.10 and 3.0 °, preferably between 0.6 ° and 1.0 °. It should be noted at this point that the dimensions described are based on the distance between the opposing inner or outer surfaces 18 of the components, the diameter, the circumference along an envelope or a Hüll line and the cross-section or the cross-sectional area respectively in one of the aligned perpendicular to the longitudinal axis 14 planes and always the same spatial direction for determining the dimensions 13,17 can relate.
As can further be seen from this illustration, the end 6 has an open end face 19, which can be closed by the closure device 9, which can be opened as required. For this purpose, the closure device 9 consists of a cap 20 comprising the open end 19 and a sealing device 21 held therein, such as a sealing plug 22 made of a pierceable, highly elastic and self-sealing material, such as e.g. Pharmaceutical rubber, silicone rubber or bromobutyl rubber. This cap 20 is usually arranged concentrically to the longitudinal axis 15 and formed by a cap-shaped annular jacket 23. Between the cap 20 and the sealing device 21 are means for coupling, such as coupling parts 24 to 27 of a coupling device 28, consisting in the cap 20 from at least over the inner circumference partially arranged 8/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Projections 29, 30, optionally a retaining ring 31, and in the sealing device 21 from a projecting at least partially over its outer periphery approach 32nd
The sealing device 21 is formed in the present embodiment by the sealing plug 22 and has a circumferential and approximately concentric with the longitudinal axis 15 arranged cylindrical sealing surface 33 which in its sealing position in the portion of the end 6 on the inner surface of the receptacle 5 for Plant comes. As a result, the inner surface of the receptacle 5 should be formed in its surface quality as a sealing surface in this section. Furthermore, the sealing device 21 has an approximately perpendicular to the longitudinal axis 14 aligned, further sealing surface 34 which closes in cooperation with the voltage applied to the inner surface sealing surface 33, the interior 10 of the receptacle 5 at the open end face 19 against the outside environment or seals , As a result of the at least regional arrangement of the extension 30 between the projection 32 protruding beyond the sealing surface 33 and the open end 19 of the receptacle 5, adhesion or strong adhesion of the projection 32 directly to the end face 19 can be avoided.
Furthermore, the sealing device 21 may preferably have on the side facing the retaining ring 31, a recess 35 which has approximately the same cross-sectional area as an opening 36, wherein this opening 36 is formed in its dimension such that an unhindered passage of a not shown here cannula and a subsequent piercing through the sealing device 21 is possible.
The coupling part 26 forming the projection 32 of the sealing plug 22, which protrudes over the sealing surface 33 at least in partial areas of the circumference flange is supported between the extensions 29 and 30 and optionally the retaining ring 31, in two in the direction of the longitudinal axis 14 from each other arranged distanced and perpendicular to this aligned planes and for example as at least partially or annular circumferential projections or Arretierfortsätze are formed, which form a groove-shaped receiving area on the inside of the cap jacket 23 for the projection 32 of the sealing plug 22. For secure mounting of the sealing device 21 in the cap 20, it is additionally possible to use the retaining ring 31 between the projection 32 and the extension 29. In this case, the retaining ring 31 has a larger outer diameter than an extending between the extensions 29 and 30 inner dimension in the direction perpendicular to the longitudinal axis 14. Similarly, the diameter of the opening 36 of the retaining ring 31 is smaller than a largest outer dimension of the projection 32 in a plane perpendicular to the longitudinal axis 14. However, this outer dimension of the sealing device 21 is dimensioned so that it is greater than the inner dimension 13 of the inner cross-section and thus of the inner space 10 at least twice the wall thickness 12 of the receiving container 5 After the extension 30, the Forming coupling part 25, having an inner opening width, which essentially corresponds to the inner dimension 13 of the receptacle 5 in its upper end 6, there is a very good support of the projection 32 in the cap 20 and a good seal between the interior 10 of the Receiving container 5 and the receiving device 1 surrounding atmosphere. This inner opening width can also be chosen to be larger than the inner dimension 13 of the receptacle 5, whereby a lateral abutment of the extension 30 on the outer surface 18 of the receptacle 5 is possible.
Above all, the tightness of the closure device 9 for the open end face 19 of the receiving device 1 is further improved if an outer diameter of the sealing device 21 in the region of its sealing surface 33 in the relaxed state outside of the receptacle 5 is greater than the inner dimension 14 of Receiving container 5 in the sealing device 21 facing area.
Furthermore, in the relaxed, unmounted state, a longitudinal or vertical extension of the projection 32 of the sealing device 21 in the direction of the longitudinal axis 14 is greater than a distance of a groove-shaped receiving area or a groove-shaped recess between the Austrian patent office AT 500 459 B1 Due to the above-described dimensional differences between the groove-shaped receiving area or the groove-shaped recess and the length dimensions of the projection 32 and the thickness of the retaining ring 31 in the direction of the 2010-08-15 Longitudinal axis 14 there is a bias of the projection 32 between the two extensions 29, 30. This simultaneously causes a compression and bias of the sealing device 21 with respect to the cap 20 and optionally additionally causes a tight fit of the retaining ring 31 and a whopping plant of the two End faces of the neck 32 in the region of the two extensions 29,30.
It is advantageous, furthermore, if the cap jacket 23 is formed as a cylinder stump jacket or as a truncated cone jacket, whereby overreaching of the cap jacket 23 in the region of the upper end face 19 is ensured.
In addition to the above-described coupling device 28 between the cap 20 and the sealing plug 22, a further coupling device 37 is provided between the receptacle 5 and the cap 20, which has been shown here only simplified. The detailed description of the coupling device 37 forming parts takes place in the following figures.
Thus, the cap 20 has two in the direction of the longitudinal axis 14 spaced from each other end portions 38, 39, wherein in the illustrated embodiment, the open end portion 39 is arranged across the open end 19 of the receptacle 5 and cross the end face 19 to close or even adjoining the extension 30 comes up. In the position shown here, the end face 19 fits snugly against the surface of the extension 30 facing this. To achieve this applied or almost adjacent position is further provided between the cap 20 and the receptacle 5, a threaded assembly 40. A first part of the thread assembly 40 is disposed on an inner surface 41 of the cap skirt 23 and a second part of the thread assembly 40 on the outer surface 18 of the receptacle 5 extending. It should be noted at this point that the threaded arrangement 40 or the parts forming it have only been shown schematically in this figure in a simplified manner.
In previously known coupling devices between the cap 20 and the receptacle 5 5 parts of a threaded assembly 40 were known both in the region of the inner surface 41 of the cap skirt 23 and in the region of the outer surface 18 of the receptacle, wherein the assembly of the cap 20 and the closure device 9 has been brought into engagement with the receptacle 5 either by transferring and applying a torque to the cap 20 and / or the receptacle 5 about the longitudinal axis 14 or by a simple Aufschiebevorgang in the direction of the longitudinal axis 14 with each other. Thus, in the choice of the first joining possibility by the torque acting on the cap 20 and the receptacle 5, a rotational movement is achieved, wherein by the thread assembly 40, a relative axial movement in the direction of the longitudinal axis 14 was achieved during the Aufschraubvorganges. The rotational movement could be carried out until the open end 19 has been moved into the position shown in FIG. 1 in the interior of the cap 20. In this case briefly described here mounting process, it was always necessary to apply at least one of the components to be assembled with a torque and the associated rotational movement about the longitudinal axis 14 so as to accomplish the Aufschraubvorgang.
The further described joining option, namely the overlapping of the closure device 9, in particular the cap 20 on the open end 19 of the receptacle 5 is made possible by the elasticity of the cap 20 and the cap jacket 23, which in turn again the threaded assembly 40 with each other is brought, however, the complete end positioning of the cap 20 relative to the receptacle 5 was not perfectly accessible in all applications. In addition to pushing over or screwing the cap 20 onto the receptacle 5, insertion of the sealing plug 22 of the sealing device 21 into the open region of the interior 10 of the same always takes place. 10/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Thereby, the above-described sealing of the inner space 10 with respect to the external environmental conditions in the region between the sealing surface 33 of the sealing plug 22 and the inner surface of the inner space 10 is achieved.
These two known joining options described above have the disadvantage that for screwing or unscrewing the cap 20 on the receptacle 5, a torque must be applied or that when sliding the cap 20 over the threads in consequence of the elastic deformation of the cap 20th or the cap jacket 23 has not taken in all cases, the cap or closure device 9, the fully patched end position or even damage to the threads have occurred.
2, the components shown in FIG. 1 for assembly to form the receiving device 1, namely the closure device 9 are shown with the here open end 6 of the receptacle 5 in a still separate position, in turn, in order to avoid unnecessary repetition, reference is made to the detailed description of the individual components to the preceding Fig. 1 or reference. Likewise, the same component designation as in the preceding Fig. 1 are used for the same parts.
In the region of the open end face 19 of the receptacle 5, a first part of the thread assembly 40, such as a thread 42, is shown in simplified form. In the cap 20 shown in half section is on the inner surface 41 between which, the receiving container 5 facing end portion 39 and the extension 30, a further part of the thread assembly 40, such as another simplified thread 43 shown also shown.
The receptacle 5 is held by means of a holding device 44 shown in a preferred position shown here preferably, wherein it is additionally possible to support the here closed end 7 of the receptacle 5 on a support surface 45 shown simplified.
In the representation of the cap 20 selected here, the sealing plug 22 has been omitted for better clarity, so as to make the thread arrangement 40, in particular the thread 43 shown here, more readily apparent. So can for the assembly or. Joining the cap 20 with the sealing plug 22 disposed therein on the here open end 6 of the receptacle 5 by means not shown in detail devices such. Assembly machines or similar from the known prior art manufacturing facilities are placed.
Furthermore, a portion of a mounting device 46 is shown here in simplified manner above the cap 20, which in the direction of the longitudinal axis 14 according to registered double arrow in the direction of the receptacle 5 and in the opposite direction by means of one or more not shown here Adjustment is adjustable via adjusting means in their position relative to the stationary held receptacle 5 is or are. This mounting means 46 may e.g. be formed by a corresponding pressure plate which by means of known actuating means, such. a cylinder-piston assembly, spindle drives, gear assembly, magnetic or hydraulic drives, etc. is placed in the predeterminable movement. Both a simple but also multiple arrangement is possible.
Between the mounting device 46, in particular the pressure plate, and facing away from the receptacle 5 end portion 38 of the cap 20 is further simplified a thrust bearing 47 is shown, with which it is possible that impacted on the adjusting means or the mounting device 46 on the cap Compressive force in cooperation with the threads 42, 43 of the thread assembly 40, the cap 20 in a relative to the receptacle 5 relative rotation or. To bring pivoting movement or to generate them and so to achieve the joining process or assembly of the closure device 9 with the receptacle 5. In this case, a plurality of these thrust bearings 47 can be held in a corresponding distribution on the pressure plate, whereby the joining or assembly process can take place in a space-saving manner with a corresponding multiple arrangement of units to be mounted of the receiving devices 1 ,
By applying a pure compressive force in the direction of the longitudinal axis 14 and the implementation of this compressive force on the cooperating parts of the thread assembly 40, the relative rotational or pivotal movement and associated screwing the closure device 9 is effected on the receptacle 5.
In this embodiment shown here project the threads 42 on the outer surface 18 of the receptacle 5 in the direction away from the longitudinal axis 14 direction. The first threads 43 of the thread assembly 40 in the region of the inner surface 41 of the cap 20 and the cap jacket 23 protrude in the opposite direction, ie, starting from the inner surface 41 in the direction of the longitudinal axis 14. In the joining or assembly position, the individual co-operating threads 42 and 43 overlap.
In this insertion process is yet to make sure that the sealing plug 22 not shown here with its inserted into the interior 10, or as shown in FIG. 1, already used plugs 48 always a sealing position relative to the receptacle 5 occupies. Likewise, attention must be paid to a perfect retention of the sealing surface 33 of the plug 48 superior projection 32 within the cap 20.
As already described above, the inserted into the interior 10 of the stopper plug 48 of the sealing plug 22 in its untensioned state has a larger outer dimension, as the receptacle 5 in the area to be used, whereby in choosing the pressure to be applied for overcoming the Resistance due to the caused between the plug 48 and the inner wall of the interior 10 friction is considered. As a result, the pressure force to be used for generating the relative rotational or pivoting movement between the closure device 9 and the receptacle 5 should be between 10 N and 50 N in size.
In order to facilitate the insertion movement, it is advantageous if, prior to assembly, at least one component forming the receiving device 1 is applied at least in regions in the region of the coupling device 37 to a coating (not illustrated here). For example, this coating can be applied to the part of the thread arrangement formed on the receptacle 5, and / or onto the part of the thread arrangement 40 arranged in the cap 20 and / or on at least one of the facing sealing surfaces 33, 34 in the region of the stopper 48 or receptacle 5 applied. This coating serves to reduce the friction between the components to be assembled. It is possible, e.g. to choose different coatings in the range of the thread assembly 40 and between the sealing plug 22 and the receptacle 5.
As a coating for facilitating the insertion movement of the sealing plug 22 of the sealing device 21, e.g. Silicone oils, waxes, waxy polymers, fatty alcohols, fatty acid esters, fatty acid amides can be used. Likewise, however, also lubricants or lubricant additives can be mixed or introduced into the coating and applied to the cap 20 and / or the receptacle 5 and / or the sealing device 21 for reducing the frictional forces. Thus, the coating comprises at least one lubricant or lubricant additive. Regardless of this, it is also possible to add at least one lubricant or a lubricant additive already intended for the preparation of the cap 5 mixture or granules and melt the lubricant together with the mixture or granules to form the plastic melt in a known form or soften , whereby the lubricant or the lubricant is or are already part of the cap material.
The coating and / or the lubricant additives or the lubricant (s) mixed or incorporated therein and / or dissolved therein can be designed such that they not only greatly reduce the sliding friction between the components to be joined, but also Austrian Patent Office AT 500 459 B1 2010-08-15 also increase the static friction to prevent inadvertent release of the components during normal use. As a result, however, a specific opening movement of the closure device 9, in particular the cap 20 from the receptacle 5, can also be carried out simply for a later access to the interior 10, as is described, for example. is necessary for sampling from the collected medium.
Furthermore, in the area of the inner surface 41 of the cap 20 at the thread 43 is shown in simplified form that this to a perpendicular to the longitudinal axis 14 aligned plane 49 a pitch angle 50 from a selected range with a lower limit of 2 °, preferably 3 °, in particular 5 °, preferably of 8 °, 10 °, 13 °, 15 ° and having an upper limit of 30 °, preferably 25 °, in particular 20 °, preferably of 16 °, 13 ° or 12 °. For test series, pitch angles 50 with a size of 9 °, 10 ° and 11 °, 12 ° have proven to be favorable.
Regardless of this, it would also be possible, the mounting means 46 and the pressure force not on the cap 20 but on the here closed end 7 of the receptacle 5 act and in the reverse manner, the cap 20 to hold stationary and the receptacle 5 by means the threaded assembly 40 under the influence of the generated compressive force on the receptacle 5 in the intended position in the cap 20 to rotate into.
Instead of the assembly or joining operation described here in FIG. 2, however, another principle of operation can also be used, as will be briefly shown and described below in FIG. 10.
3 to 5, the cap 20 is now shown to form the receiving device 1 in different views, in turn, the same parts with the same reference numerals, as in the preceding Figs. 1 and 2, are designated.
In this embodiment shown here, the thread assembly 40 is designed to be more continuous in the region of the cap 20. In this case, three threads 42 distributed over the inner surface 41 are preferably provided, wherein thread starts 51 to 53 of the individual threads 43 are arranged offset in the circumferential direction relative to each other by approximately 120 °.
A thread length of or the individual threads forming the thread assembly 40 43 is in the plane perpendicular to the longitudinal axis 14 aligned plane 49 over the circumference equal to or smaller than an inner circumference of the cap jacket 23 in the region of the thread assembly 40. By the three-speed described above Thread, it is advantageous if a thread 43 extends approximately over half the inner circumference of the cap skirt 23. Furthermore, it can be seen from the representation, in particular of FIGS. 3 and 4, that the thread or threads 43 are formed projecting beyond the inner surface 41 of the cap skirt 23 in the direction of the longitudinal axis 14. To reduce the friction between the threads 43 shown here in the region of the cap 20 and the previously described briefly in FIGS. 1 and 2 threads 42, it is advantageous if the thread assembly 40, in particular the threads 42 and / or 43, at least partially with a coating not shown here are provided. In this case, only the mutually interacting sections of the individual threads 42 and / or 43 may be provided with this coating, not shown.
Regardless or beyond, it is advantageous for reducing the friction between the threads 42, 43, if they have a surface roughness in the boundaries between 0.0125 pm and 0.05 pm, at least at the respective cooperating sections.
The individual thread starts 51 to 53 are arranged close to the open and the receptacle 5 facing or cross-end portion 39 and extend due to their previously described slope or the pitch angle 50 to close to the extension 30 zoom. The pitch angle 50 and the circumferential extent of the individual 13/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Threads 43 is described in the present embodiment for the cap 20 of the receptacle 5 for a nominal size of 13 mm, as is currently a common standard size for the receiving device 1. Likewise, it should be mentioned at this point that the holder of the sealing plug 22, in particular of the projection 32, between the two extensions 29 and 30, optionally with the interposition of the retaining ring 31, can take place but other mounting options are not excluded.
6 to 9, the receptacle 5 is shown and described in more detail to form the receiving device 1, wherein in turn the same reference numerals and component designations, as in the preceding Figs. 1 to 5, are used for the same parts.
In the introduction it should be mentioned here that the description for the formation of the threads 42 relates to a receptacle 5, in particular blood sampling tube, with a nominal size in its diameter of 13 mm. In the event of deviations, in particular in diameter, the values described here must be correspondingly transferred to other nominal sizes.
As already described above, it has been found to be advantageous in this nominal size of the receiving device 1, when the thread assembly 40 is more stable, in particular dreigängig formed, whereby the cap 20 with the receptacle 5 with a previously described assembly or joining operation can be connected or coupled under application of an exclusive compressive force in the direction of the longitudinal axis 14.
As can be seen from a synopsis of Figs. 6 and 8, the individual threads 42 are arranged to form the threaded assembly 40 on the outer surface 18 of the receptacle 5 evenly distributed. In this case, thread starts 54 to 56 and threaded ends 57 to 59 limit the individual threads 42 in their longitudinal extent over the circumference. Thus, from a synopsis of FIGS. 7 and 8, it can be seen that a pitch angle 60 of the thread 42 for forming the thread assembly 40 with respect to a plane 49 perpendicular to the longitudinal axis 14 is selected from a selected range having a lower limit of 2 ° , preferably 3 °, in particular 5 °, preferably of 8 °, 10 °, 13 °, 15 ° and with an upper limit of 30 °, preferably 25 °, in particular 20 °, preferably 16 °, 13 ° or 12 ° having. For test series also pitch angle 60 with a size of 9 °, 10 ° and 11 °, 12 ° have proven to be favorable. As already described above, the thread arrangement 40 is designed to be more continuous, wherein the second part of the thread arrangement 40 likewise comprises three threads 42 distributed over the outer surface 18 or outer surface.
As described above, the two selected pitch angles 50, 60 are in the same limits and, in order to achieve a perfect Aufschraubvorgang, each chosen the same size. However, as preferred pitch angles 50, 60, values with lower or upper limits of 3 ° and 20 °, 5 ° and 16 °, 8 ° and 13 °, and 10 ° and 12 ° have also been found, wherein the size of the selected pitch angle 50 , 60 is dependent on the combination of materials of the receptacle 5, the cap 20 and the sealing device 21 and the proposed coating.
The thread starts 54 to 56 of the individual threads 42 are arranged offset in the circumferential direction to each other approximately 120 °. The same also applies to the threaded ends 57 to 59. Furthermore, immediately adjacent to each other threaded lugs 54 to 56 and threaded ends 57 to 59 each spaced apart in the circumferential direction, whereby a sum of the thread lengths of the thread assembly 40 forming threads 42 in the direction perpendicular to the longitudinal axis 14 aligned Level 49 seen over the circumference equal to or smaller than an outer circumference of the receptacle 5 in the region of the thread assembly 40. Thus, the respectively circumferentially immediately adjacent arranged threads 42 are spaced from each other in the circumferential direction. In this embodiment shown here, the threads 42 extend between their thread beginning 54 to 56 and their threaded end 57 to 59 over the circumference seen over an angle 61, which for example can be between 50 ° and 80 °. Favor this angle 61 is selected with in about 65 0. In this section, the threads 42 have their full thread height 62, as best seen in the enlarged view of FIG.
8, it can be seen from this further that the thread 42 has a threaded outlet 63 in the section of its thread beginning 54 to 56 starting from the full thread height 62 towards the outer surface 18 of the receiving container 5 which is constantly decreasing in flea. Likewise, it is advantageous if the thread or threads 42 in the section of their threaded ends 57 to 59, starting from their full thread height 62, towards the outer surface 18 of the receptacle 5 have a further threaded outlet 64, which is also formed in its fleas steadily decreasing. In most cases, the threaded outlet 63 and / or 64 is formed by a transition radius 65. But this thread outlet can also have any other form technical training to facilitate the joining process. This can also be chosen differently depending on the material used.
Characterized in that the individual threads 42 seen over the circumference do not overlap in their longitudinal extent or do not overlap and thus the adjacent adjacent thread starts 54 to 56 are distanced from the threaded ends 57 to 59, it is possible for the Fierstellungsvorgang , In particular, the injection molding process, the mold parting plane to form the receptacle 5 in the threads respectively at their highest point or the highest line extending the same and between the immediately adjacent threaded starts 54 to 56 and threaded ends 57 to 59 this through a connecting line in the area the outer surface 18 extending to connect with each other and further form the mold parting plane in this connection line. As a result, a significant share of costs can be saved in the production of molds, which also additionally higher cycle times are possible. Such an arrangement of the mold parting plane for forming external threads is known, for example, from US Pat. No. 3,926,401 A and US 2001/0055632 A1. A similar design for internal thread is known from DE 30 47 856 C2, DE 296 18 639 U1 of US 2,133,019 A, US 4,079,475 A, US 4,188,178 A and US 5,667,870 A known.
By the spaced over the circumference distanced and thus non-overlapping or non-overlapping threads 42 demolding of the receptacle 5 from the mold not shown here by a mold opening in the pure axial direction, ie in the direction of the longitudinal axis 14, respectively. As a result, a simpler tool design and a cost reduction associated with it while saving space is achieved. Likewise, the cycle time due to simpler and shorter movements for opening and closing the mold can be achieved thereby. Likewise, a multiple arrangement of cavities for the formation of the receptacle 5 in a single mold is possible and thus still a higher and more favorable output can be achieved.
As can now be better seen in FIG. 9, the thread 42 has seen in its cross-section, that is, in a plane parallel to and centered by the longitudinal axis 14, starting from its full thread height 62, towards outer surface 18 of the receptacle 5 a mutually different transition region, whereby a threaded cross-section of the thread 42 is formed asymmetrically in this plane.
The thread 42 has in the region of the outer surface 18 in a nearly parallel direction to the longitudinal axis 14 or in the reference plane described above, a base width 66, which may be 1.3 mm in the present embodiment. Starting from this base width 66, the thread 42 in the considered plane on the open 15/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Front side 19 of the receptacle 5 side facing an exclusive radius 67, which, starting from the outer surface 18 toward the full thread height 62 passes. In the section of the full thread height 62, the thread 42 has a likewise parallel to the longitudinal axis 14 extending vertex width 68, in the region of the mold parting plane can be arranged to extend. This vertex width 68 is approximately 0.6 mm in the above-described base width 66 of 1.3 mm.
On the side facing away from the open end face 19, the thread 42, starting from the outer surface 18, toward the full thread height 62 on a direction towards the open end face 19 inclined transition surface 69, said angle 70 in the present embodiment 5 ° to the plane perpendicular to the longitudinal axis 14 aligned plane 49. Between the parallel to the longitudinal axis 14 extending vertex width 68 and the transition surface 69, a further radius 71 is provided, which has a size of 0.3 mm in the present embodiment.
By the different choice of the two radii 67, 71 to obtain an asymmetric thread 42, in which the first radius 67 is selected to be greater than the further radius 71. Thus, the first radius 67 in this embodiment is 0.7 mm and passes from the outer surface 18 to the parallel vertex width 68 of the thread 42 via. This vertex width 68 of the thread 42 may also be referred to as a vertex surface 72.
The apex surface 72 and the transition surface 69, in a view of the thread cross-section can also be referred to as a crest line or transition line or boundary line.
Furthermore, it can still be seen from FIG. 7 that the thread beginning 54 of the thread 42, in particular the thread outlet 63 thereof, comes close to the open end face 19 of the receptacle 5. This ensures that in the joining operation or assembly process with the closure device 9, the intermeshing threads 42, 43 for forming the thread assembly 40 up to the full closure position, as can be seen in Fig. 1, are always in engagement whereby a clear screwing and unscrewing the closure device 9 from the receptacle 5 is always possible.
FIG. 10 shows a further and, if appropriate, independent solution for joining or mounting the receiving device 1, similar to the embodiment shown in FIG. 2. In this case, illustrated components for assembly to form the receiving device 1, namely the closure device 9 are shown with the open end 6 of the receptacle 5 in a still separate position, in turn, to avoid unnecessary repetition, to the detailed description of the individual components Reference is made to the preceding Fig. 1 to 9 or reference. Likewise, the same component designation as in the preceding FIGS. 1 to 9 is used for the same parts.
Also in this illustration, the cap 20 is simplified in half section and without sealing device 21, wherein the cap 20 is still seen in a distant position from the receptacle 5 in the direction of the longitudinal axis 14. Likewise, the thread assembly 40 is shown simplified. The reference numerals have been entered analogously to the embodiment shown in FIG. 2, wherein, in order to avoid unnecessary repetition, a detailed description is omitted here and reference is made or made to the preceding statements.
In this embodiment shown here, in contrast to the mounting device 46 shown in FIG. 2, the cap 20 in the region of its outer cap jacket 23 in a receptacle 73 of a support plate 74 on the one hand rotationally fixed about the longitudinal axis 14 and on the other hand stationary in the direction of the longitudinal axis 14 held relative to the holding plate 74. The application of the compressive force (F) is again effected by means of adjustment not shown in more detail here, such as, for example, adjusting means. Again, a multiple arrangement of the receptacles 73 in the holding plate 74 is possible, even advantageous, whereby a plurality of caps 20 or already fully assembled closure devices 9 inserted therein and are held stationary both about the longitudinal axis 14 and in the same direction.
As a result of the here conical or frusto-conical outer surface of the cap 20 and cap jacket 23 and the corresponding counter-trained receiving 73 can be made with respect to tolerances a positional fixation of the cap 20 with respect to the longitudinal axis 14 and in the same direction , However, a sufficient positional fixation is also possible with almost cylindrical caps 20. In this case, an outer surface of the cap 20 that is profiled over the circumference can favor the positional fixation for the assembly or joining process.
Regardless, it would also be possible to perform the support plate 74 divided accordingly and provide in these attacks in the direction of the longitudinal axis 14 to a clear longitudinal positioning of the cap 20 and closure device 9 provided in the holding plate 74 holding or Pretend locking position. For this purpose, appropriate stops or approaches can be provided, which have not been shown here in detail. By a shared executed holding plate 74 in the area of the receptacles 73 so a clamping and thus radial fixation of the closure device 9 and cap 20 with respect to the longitudinal axis 14 within the holding plate 74 can be achieved.
Due to this selected arrangement, a compelling mutual alignment of the thread assembly 40 of the receptacle 5 and the closure device 9 against each other before the joining process is no longer necessary, which also costs for the otherwise necessary alignment operations can be saved here. This cost reduction is not only due to the shortening of the cycle times.
The receptacle 5 is rotatably supported in this embodiment via the thrust bearing 47 on the support surface 45 about the longitudinal axis 14, wherein the axial alignment or pre-positioning of the same relative to the cap 20 and closure device 9 this is associated with a positioning device 75. In this positioning device 75, a guide hole 76 shown in simplified form is arranged, which ensures, for example, a vertical orientation of the receptacle 5 for the assembly or Fügelage. This guide opening 76 has a sufficient clearance to the outer surface 18 of the receptacle 5 so as to be able to perform about the fixed cap 20 generated rotational or pivotal movement about the longitudinal axis 14 can. In addition, different coatings may be provided on the outer surface 18 facing the inner surface of the guide opening 76, which are not shown here. Likewise, it is also possible to provide the guide opening 76 only partially over the entire outer circumference of the receptacle 5, wherein for a multiple arrangement of receptacles 5 and closure devices 9 but for example only individual vertical webs between the immediately adjacent receptacles 5 may be provided, which ensure a sufficient secure guidance or positioning and rotation or pivoting with respect to the closure device 9 to be joined.
To simplify the automated assembly, it is also possible to provide the thrust bearing 47 or on a movable mounting base, being filled in a separate filling the mounting bracket with a corresponding number of receptacles 5, in another station, the closure devices to be joined 9 also in its own mounting bracket on which the support plate 74 is required pivotally mounted or rotatably mounted, also to feed or insert them into the receptacles 73, then subsequently to move the so pre-filled mounting bracket to its own assembly station, in which the joining process according to the invention , namely to screw together with the application of a pure compressive force. This has the advantage that so a plurality of receptacles 5 and / or closure devices 9 and caps 20 independently of each other in the arranged on the mounting supports or workpiece carriers holding plates 74 and / or 17/42 Austrian Patent Office AT 500 459 B1 2010-08- 15
Positioning devices 75 can be pre-loaded accordingly and perform the joining process in its own separate assembly station.
As now described in detail in the individual figures, the placement process of the closure device 9 takes place on the receptacle 5 by a pure implementation of acting in the direction of the longitudinal axis 14 axial force in a relative rotational or pivotal movement between the components to be joined until the maximum screw-in path eg is limited by a mechanical stop between the receptacle 5 and the cap 20 and / or the sealing device 21. By this mechanical definition of the length of the Einschraubweges by at least partially co-operating threads 42, 43 of the thread assembly 40 they are over the entire up or Einschraubweg engaged with each other, which starting from the fully screwed position unscrewing or loosening the closure device 9 of Receptacle 5 can be performed by a relative rotational or pivotal movement between the components to be separated. Due to the uniquely predetermined relative position, in the fully screwed position between the cap 20 and the receptacle 5 necessary for releasing Abschraubweg is determined by the circumferential length or the angular extent of the overlapping or cross threads 42, 43 and takes place in an opposite relative movement between the components.
This unscrewing is controlled by the at least partially co-operating threads 42, 43, in addition also still held on the coupling device 28 in the cap 20 sealing device 21 also mitentfernt or lifted from the receptacle 5 simultaneously. For a simultaneous secure decrease or separation of the closure device 9 from the receptacle 5 is possible. Furthermore, a jerky opening or loosening of the sealing device 21 is avoided by the cooperating threads 42, 43 from the receptacle 5, wherein an inadvertent leakage of stored in the interior 10 of media 3, 4 and the mixture 2 is avoided. As a result, the handling of the operating personnel is safer, which possible infection by leaking subsets and thus possible connected infections are ignored. By this predeterminable screwed-on end position but also a decapping of the closure device 9 from the receptacle 5 by mechanical devices or devices is possible, as always a predeterminable Abschraubweg and thus defined, relative rotation or swivel angle between the components to be separated is clearly defined.
In Fig. 11 different training options of the receptacle 5 are shown simplified in a single figure, but these can also be arbitrarily combined with each other as well as with any of the training options described above. For better clarity, the illustration of the closure device 9 is omitted in this figure. Likewise, to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. In addition, the same reference numerals or component designations are used for the same parts as in the preceding FIG.
In addition to the embodiments previously described in FIGS. 1 to 10, however, it is also possible to use the receptacle 5 in conjunction with the closure device 9, not shown here, for a receptacle 1. In this illustration, a separating device 77 is provided, which is to be inserted into the receptacle 5 before closing the inner space 10 and is shown here in a position distant from the receptacle 5. In this case, this separating device 77 according to the embodiments, as described in WO 02/078848 A2 of the same applicant, be formed. For the special design of the separation device, the receptacle and the closure device is made to the aforementioned WO 02/078848 A2 reference and incorporated this disclosure in the present application. The selected terms are analogously to the terms and representations chosen here. The separating device 77 is inserted into the inner space 10 or a receiving space 78 in the region of the open front side 19 in the receptacle 5 and is located there in the so-called starting position, in which, after the closure of the receiving container 5 with the closing device 9, the inner space 10 is additionally lowered simultaneously with it, or even earlier, to a lower pressure than the ambient pressure, in particular evacuated. The filling of the receiving device 1 is carried out in a conventional manner, for example in the form of a blood sample, with the associated piercing of the sealing device 21 with a cannula, not shown here, whereby the mixture 2 shown in FIG. 1 from the media 3 and 4 , in particular blood, flows through the flow channel or connection opening through the separating device 77. Subsequently, the separation of the mixture can be carried out by a centrifuging, as has already been described in detail in WO 02/078848 A2. In the sealing position of the separator 77 within the receptacle 5, this is in the so-called working position, which is dependent on the total filling volume of the receptacle and the volume proportion of the components of the mixture to be separated 2. Usually, the working position is approximately in half of the longitudinal extent be selected of the available receiving space 78 of the receptacle 5.
In the region of the starting position, which is adjacent to the end 6 of the receiving container 5, for the separating device 77 to be inserted into the inner space 10 or the receiving space 78, different embodiments of the retaining device 79 are shown for the latter. It is shown here in the right part of the figure that the retaining device 79 by at least one over the circumference of an inner surface 80 in the direction of the longitudinal axis 14 projecting projection 81 and / or by at least partially over the circumference of the inner surface 80 in the direction the longitudinal axis 14 projecting web 82 is formed. In this case, both the projection 81 and / or the web 82 can only be arranged in a continuous manner over the circumference and possibly also continuously over the entire circulation of the inner surface 80 over certain regions.
11, a further embodiment of the retaining device 79 is shown, which is formed by a reduction of the inner dimension 13 of the receiving space 78, starting from the open end face 19, the sealing surface 34 for here not closer illustrated sealing device 21, in particular the sealing surface 33 of the sealing plug 22, is formed. This reduction can be effected by, for example, starting from the end 6 of the receptacle 5 to the retaining device 79, the normal wall thickness 12 of the receptacle 5 and from the retainer 79 in the direction of the other end 7 has a greater wall thickness, the magnification of the Wall thickness 12 by an offset of the inner surface 80 in the direction of the longitudinal axis 14 takes place. Regardless, it is also possible to choose the wall thickness 12 of the receptacle 5 between the starting position and the other end 7 in the range of the usual wall thickness 12 and only the wall thickness between the starting position and the open end 6 of the receptacle 5 form less.
Depending on the design of the retainer 79 is a positional positioning of the separator 77 in the direction of the longitudinal axis 14 until reaching a predeterminable centrifugal force, in which the retention forces are overcome and the displacement of the separator 77 relative to the receptacle 5 up to reaching the working position , predeterminable.
To achieve a different secure positioning or relative positional fixation of the separating device 77 in the region of the starting position can between the receptacle 5 and the separator 77, the retainer 79 by a not shown here groove-shaped recess, which all around the inner circumference of the inner surface 80 in this is arranged in depth, be formed. In order to achieve a secure positioning or relative positional fixation of the separating device 77 in the region of its working position, a positioning device 83 can be arranged between the receiving container 5 and the separating device 77 is preferably formed by a mechanically acting stop. This positioning device 83 can be formed, for example, by reducing an inner dimension 84 of the receiving space 78 or inner space 10, optionally forming a stop surface 85 oriented approximately perpendicular to the longitudinal axis 14. At this stop surface 85, both the sealing device arranged in the first end region of the separating device 77, in particular the sealing lips, as well as the further end region thereof or its components can be brought into abutment. Thus, a sealing, in particular liquid-tight sealing of the separate media 2, 3 is achieved after completion of the centrifuging process over a longer storage life. This positioning device 83 thus forms a mechanical stop for the separating device 77 for terminating the relative adjustment movement relative to the receiving container 5 in the direction of the longitudinal axis 14 toward the further end 7.
The reduction of the interior 10, starting from the starting position towards the working position or between the first and further end 6, 7, is also realized in this receptacle 5 shown here and forms a control cam for the independent closing of the flow channels or in Area of the separator 77 from. The tapering of the receptacle 5 described above in its inner space 10 or receiving space 78 between the two mutually spaced planes 15, 16 may be between 0.1 ° and 3.0 °, preferably between 0.6 ° and 1.0 °. In a receptacle of nominal size 13 mm (diameter) with the nominal length 100 mm, the cone or cone angle relative to the longitudinal axis 14 and the outer surface 18, for example, be 0.34 °. This conical or cone angle is chosen to be constant over the entire outer longitudinal extent between the two ends 6, 7. The conical or cone angle of the inner surface 80, also with respect to the longitudinal axis 14, can also be 0.46 in the first partial area between the first end 6 and the positioning device 83, for example 0.46 ° and between the positioning device 83 and the plane 16 ° amount. Likewise, it is also possible to form the portion of the sealing surface 34 cylindrically, so as to facilitate the insertion of the sealing plug 22 of the sealing device 21 - see Fig. 1 -.
FIGS. 12 to 16 show a further possible and optionally independent embodiment of the receptacle 5 for forming a receptacle 1 for body fluids, tissue parts or tissue cultures that can be closed with a closure device 9 Component names as used in the preceding Figures 1 to 11. Likewise, to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1-11.
This receptacle 5 in turn serves as a receptacle 1 for body fluids, tissue parts or tissue cultures, in particular for the use of a mixture to be separated 2, consisting of at least the, a different density having media 3,4, as already shown in FIG. 1 has been simplified and described. Instead of the thread arrangement 40 described above, in the area of the open end 19 in the area of the first end 6 evenly distributed over the circumference are several, in the present case three, the outer surface 18 projecting beyond the direction away from the longitudinal axis 14 protruding extensions 86, such as this can already be deduced from the known state of the art. It would also be possible, instead of the extensions 86, to use the previously described threads 42 in connection with the threads 43 in the cap 20, as has already been explained in detail in the preceding FIGS. 1 to 10.
Starting from the open end face 19 extends in the region of the inner space 10, the sealing surface 34, which serves to bear the sealing surface 33 of the sealing plug 22 of the sealing device 21 not shown here. Following this, the further area of the interior 10 is provided for the insertion of the separating device 77 shown in simplified form in FIG. 11, as best seen in FIG. 13 is. In order to facilitate the filling process of the mixture through the or in the separation device or through this formed flow channel or connection opening, at least one through-flow channel 87 in the region between the container wall 11 of the receptacle in the starting position of the inserted or deployable separation device 77 5 and the separator 77 is formed. This flow-through channel 87 serves to spend the remaining in the interior 10 between the separator 77 and the other end 7 remaining amount of air to the separator 77 over into the interior 10 between the separator 77 and sealed by the sealing device 21 interior 10. Likewise, the flow-through channels 87 can also serve to allow residual quantities of the mixture 2, which have not flowed through the flow channel or the connection opening in the region of the separating device 77, also into the interior 10 of the receiving container 5 formed between the separating device 77 and the further end 7 spend.
As can be seen from a synopsis of FIGS. 12 to 16, here the throughflow channel 87 is formed by at least one recessed recess 88 formed in the inner surface 80 of the container wall 11. This recess 88, recessed in relation to the inner surface 80, has, starting from the inner surface 80 in the radial direction towards the outer surface 18, a depth 89 between 0.1 mm and 1.0 mm, preferably between 0.2 mm and 0.5 mm , on. Preferably, a plurality of distributed over the inner circumference arranged recesses 88 are provided, in which case a symmetrical division in relation to the longitudinal axis 14 over the inner circumference is advantageous. However, it would also be possible to arrange the recess 88 continuously over the inner circumference and thus to form it in the form of a groove-shaped depression or hollow cylinder.
The recess 88 has a coaxial with the sealing surface 34 arranged base surface 90, which thus limits the recess 88 in depth. Between the base surface 90 and at least one of those in the direction of the longitudinal axis 14 spaced from each other boundary surfaces 91, 92 each have a first transition surface 93 is arranged. Furthermore, a further transition surface 94 can be arranged at least between one of the boundary surfaces 91, 92 of the recess 88, distanced from one another in the direction of the longitudinal axis 14, and the inner surface 80. These two transition surfaces 93, 94 may be selected such that they already form the mutually distanced boundary surfaces 91, 92. These boundary surfaces 91, 92 are in the direction of the longitudinal axis 14 as viewed across a longitudinal extent 95 distanced from each other. In this case, the longitudinal extension 95 ends in front of the sealing surface 33 of the sealing plug 22 zuwendbaren sealing surface 34. In the direction away from it, the longitudinal extent 95 of the recess 88 maximum up to reaching the working or. Separation position of the separator 77 rich. Preferably, however, this is chosen to be shorter, only to form the flow passage 87 in the region of the inner surface 80 and the separator 77 during the filling process and only after a slight adjustment of the separator 77 towards its working position, only a passage of a component of the mixture through the To allow flow channel or the connection opening in the region of the separator 77. Otherwise, a sealing contact of the sealing lips of the separating device 77 on the inner surface 80 of the receptacle 5 to achieve a perfect separation result is preferable.
In one possible embodiment, five recesses 88 are provided in the receptacle 5 over the inner circumference, which have a size or extent in the circumferential direction of 1.9 mm seen at a depth of 0.4 mm. These recesses have in the direction of the longitudinal axis 14, the longitudinal extent 95 of 3 mm. It is essential in the choice of the depth 89 of the recess 88, that in this area, the container wall 11 still has sufficient strength that is sufficient to ensure the shelf life of the receiving device 1 in its unused state (maintenance of the vacuum). Here, depending on the manufacturer, a period of e.g. Guaranteed within 18 months, within which the interior 10 preset prepress is maintained. In the case of this design, consideration must be given to the oxygen and water vapor permeability of the material, especially in this area.
As best seen in FIGS. 12 and 16, boundary surfaces 96, 97 oriented parallel to the longitudinal axis 14 delimit the recess 88 in the circumferential direction. In cooperation of the two boundary surfaces 96, 97 and the depth 89 of the recess 88, a flow cross-section 98 is limited or fixed, which is dimensioned such that both subsets of the mixture 2 and residual amounts of air can flow simultaneously, but in the opposite direction, without a Clogging or laying of this flow-through channel 87 and the flow-through channels 87 associated therewith. In this case, the minimum flow cross-section 98 of the at least one flow-through channel 87 in the plane 49 oriented perpendicular to the longitudinal axis 14 is at least 0.4 mm 2. This size represents the minimum extent of that cross-sectional area which is necessary when using the receiving device 1 as a blood sampling tube to allow a proper flow of a portion of the mixture or medium to be filled and a simultaneous displacement of residual amounts of air in the opposite direction of flow.
In order to reduce or prevent the adhesion or deposition of constituents of the mixture 2 in the region of the recess 88, in particular of the boundary surfaces 91, 92 and / or 96 or 97, it is advantageous if at least one of these boundary surfaces 91, 92, 96, 97 and transition surfaces 93, 94 is concavely curved. But it would also be possible, one of these boundary surfaces 91, 92, 96, 97 and / or transition surfaces 93, 94 planar form. For the removal of the receptacle 5, in particular its core for forming the interior 10, it is advantageous if the boundary surface 91 closer to the open end 19 or the transition surfaces 93, 94 form a relatively shallow transition towards the sealing surface 34 or inner surface 80 , as best seen in FIG. 15. In this case, the boundary surface 91 is planar and the transition surface 94 arranged between the latter and the sealing surface 34 or inner surface 80 is convex, in particular by a radius, and the transition surface 93 formed between the base surface 90 and the boundary surface 91 is concave, preferably also by a radius. educated.
In order to reduce or prevent adhesion of the constituents of the mixture 2 in the region of the inner surface 80, in particular of the flow-through channel 87 or the recess 88, it is advantageous if this surface has a surface structure which corresponds to the An liable to hinder or prevent. Here, in particular, a surface structure according to the "lotus flower effect" can be used. Find use. Thus, especially in this very sensitive area, a deposit or adherence of residues of the mixture 2 is prevented. However, this repellent surface structure can also be provided on the sealing device 21, the sealing surfaces 33, 34, the cap 20 and the separating device 77, wherein only a region-wise arrangement is possible.
In FIGS. 17 and 18, a further and, if necessary, separate training of the cap 20 and of the receptacle 5 is shown in simplified form, again in order to avoid unnecessary repetition, to the detailed description in the preceding FIG. 1 16 is referred to or referenced. Likewise, like reference numerals and component designations are used for like parts, as in the preceding Figs. 1 to 16 used.
Thus, Fig. 17, the cap 20 with the cap jacket 23, wherein on the longitudinal axis 14 facing inner surface 41 in the region between the receptacle 5 facing end portion 39 and the extension 30 parts of the thread assembly 40 are formed. The one or more threads 43 are seen here over their longitudinal course, formed by a plurality of circumferentially successively arranged and spaced from each other, first thread segments 99. The shape of the thread segments chosen here is chosen only as an example for a variety of possible embodiments and these can have a wide variety of spatial forms. Thus, these thread segments 99 also exceed the 22/42 Austrian Patent Office AT 500 459 B1 2010-08-15
Inner surface 41 of the cap jacket 23 in the direction of the longitudinal axis 14th
In FIG. 18, the thread 42 on the receptacle 5 is also formed over its longitudinal course by a plurality of further thread segments 100 arranged one behind the other in the circumferential direction and distanced from one another. These thread segments 100 can in turn have a wide variety of spatial forms and project beyond the outer surface 18 of the receptacle 5 in the direction away from the longitudinal axis direction.
Furthermore, in the region of the thread 43 in dashed lines, FIG. 17 shows in simplified form that the coating or a lubricant or lubricant additive previously described in detail may be stored in at least one depression 101 in the region of the thread 43. The depressions 101 are shown only schematically simplified and can be arranged, for example, between the individual thread segments 99 in the cap casing 23 and / or also directly in the region of the thread 43. Thus, for example, several recesses 101 distributed over the circumference in the cap casing 23 and the threads 43 may be arranged, which serve to receive the coating and / or the lubricant or a lubricant additive.
FIG. 19 shows a further possible and optionally separate embodiment of the cap 20 in conjunction with the sealing device 21 inserted therein, again in order to avoid unnecessary repetition, to the previously detailed description in FIGS. 1 to 18, respectively. Likewise, the same reference numerals and the same component designations are used for the same parts, as in the preceding Figs. 1 to 18.
As already described above, the two delimited in the direction of the longitudinal axis 14 extensions 29, 30 and optionally inserted therebetween retaining ring 31 on the inside of the cap skirt 23, the groove-shaped receiving area for the projection 32 of the sealing device 21. In this section of the groove-shaped receiving region is arranged in this embodiment in the cap casing 23 at least one enforcement 102, which forms an opening or a breakthrough or even a recess in the cap casing 23 can form.
In this enforcement 102 projects in the inserted or assembled state of the sealing device 21 a projection 32 superior projection 103 into it, which in addition to the holder or coupling of the sealing device 21 in the direction of the longitudinal axis 14 a rotation or further coupling of Sealing device 21 relative to the cap 20 around the longitudinal axis 14 is formed. This enforcement 102 may have a variety of cross-sectional shapes and be formed, for example, round, polygonal, oval, etc., wherein the enforcement is preferably a window-like opening in the cap jacket 23. If, viewed over the circumference, a plurality of openings 102 are provided in the cap casing 23, it is advantageous if they are distributed uniformly over the circumference. Thus, the individual projections 103 projecting through the penetrations 102 may also project beyond the outer surface of the cap skirt 23 and at the same time be used as a prevention for rolling or rotating the entire receptacle while lying on a flat or sloping surface. If the projections 103 protrude beyond the outer surface of the cap jacket 23 to a certain extent, they can also simultaneously serve as a handle or grip element for unscrewing the entire closure device 9 from the receptacle 5 and thus improve handling or even make it safer.
A further additional and in itself possibly independent design of the cap 20 is shown in simplified form in FIG. 19, wherein here in the, the receptacle 5 zuwendbaren and cross-end portion 39 of the cap 20 a preferably completely continuous, and the end portion 39th superior apron-shaped protective element 104 is shown in simplified form. This apron-shaped protective element 104 can only be arranged or formed on the cap jacket 23 in regions over the circumference, but preferably all around. It is possible, the protective element 104 as its own 23/42 Austrian Patent Office AT 500 459 B1 2010-08-15
To form part of the cap jacket 23 and form the protective element 104 as an integral part of the cap jacket 23. As shown in simplified form here, the protective element 104 has a continuously decreasing cross section with increasing distance from the end region 39.
An inner diameter 105 of the protective element 104 may correspond approximately to the outer diameter or the outer dimension of the receptacle 5, optionally in addition, the projection of the threads 42 on the outer surface 18 of the receptacle 5. This protective element 104 serves to form an additional leakage protection or splash protection for a user of the receiving device 1 in order to avoid unwanted contact when taking off the closure device 9, which is possible by ejecting the contents from the receiving container 5. As a result, contagions or infection of the operating personnel can be reduced or avoided at all.
FIG. 20 shows a further possible and, if appropriate, independent configuration of the receiving container 5, again referring to the detailed description in the preceding FIGS. 1 to 19 in order to avoid unnecessary repetitions , Likewise, like reference numerals and component designations are used for like parts, as in the preceding Figs. 1 to 19 used.
The receptacle 5 shown here, in turn, is preferably designed for insertion of a separation device 77, not shown here, and instead of the recess 88 shown and described in FIGS. 12 to 16 for forming the flow-through channel 87, in contrast, at least one, but preferably a plurality of the inner surface 80 of the receptacle 5 in the direction of the longitudinal axis 14 projecting ribs 106. The ribs 106 are web-shaped and preferably aligned parallel to the longitudinal axis 14. In most cases, a plurality of ribs 106 distributed over the circumference are arranged on the inner surface 80 of the container wall 11 and form between them - so seen in the circumferential direction - the flow-through channels 87 from. The separation device 77, not shown here, abuts the boundary surfaces of the ribs closer to the longitudinal axis 14 and thus faces, whereby between the separating device 77, the circumferentially spaced apart ribs 106 and the inner surface 80 of the container wall 11 or the flow channels 87th is limited or are. A minimum cross-section of this flow-through channel 87 can once again amount to at least 0.4 mm 2, but can also be made larger.
Finally, it should be added that these previously described embodiments of the receiving device 1 are blood sampling tubes whose interior 10 after closing with the closure device 9 has a lower pressure compared to the local atmospheric pressure, that is evacuated. But it can also be filled in the evacuated interior 10 only or the active ingredients.
For the sake of order, it should finally be pointed out that for a better understanding of the construction of the receiving device 1, these or their components, such as the closure device 9 and the receptacle 5, were shown partially unevenly and / or enlarged and / or reduced in size. 24/42 Austrian Patent Office AT 500 459 B1 2010-08-15
