The invention concerns a device comprising a membrane valve consisting of a part (15) forming said valve seat, wherein is provided a conduit (25, 26) circulating the product contained in the container (2, 50), and of a membrane (16) made of an elastically deformable material, tightly engaged on said part (15). The invention is characterised in that said part (15) has a general conical part, and a cross-section flaring out in the direction of the orifice (24) allowing the product to flow beyond said valve; said membrane (16) has a generally conical shape corresponding to that of said part (15), and can be tightly fitted thereon, and said membrane (16) and said container (2) comprise support means (5, 10, 11, 28, 30 to 32) to maintain the membrane (16) in its tight-fit position on said part (15).
DEVICE FOR SEALING CONTAINER
The present invention relates to a sealing device for containers, to preserve the product contained in said container from contact with ambient air or contamination by foreign matter from outside the container.
This container may in particular be a "tube", that is to say an envelope whose one longitudinal end has a neck and the other longitudinal end is closed by pinching and joining, in particular by welding, the walls of that envelope. The product can be any product it is important to protect against contact with air or against soiling, particularly a cosmetic product, a food product or a medical product.
The invention also relates to a sealing device for a container and a container structure for containing two substances separately and allowing the mixture thereof at the time of use.
International Application (PCT) No. WO 97/47531 discloses a sealing device comprising a cylindrical portion intended to be inserted into the neck of a container and two flow channels of the product contained in the container. Said cylindrical portion comprises a groove giving it the shape of a "diabolo" and is covered by an elastomeric membrane, which closely wife. This membrane allows, through its elastic deformation resulting from pressure on the container, the product flow between it and said cylindrical portion, and is pressed against this cylindrical part in the absence of such pressure, so that it performs the function of a valve.
However, this device is satisfactory in practice but has the disadvantage of involving a perfect form fit between said cylindrical portion and said membrane, failing which the seal is not obtained. This form of complementarity requires the use of relatively complex molding techniques to implement.
Moreover, it is not excluded that a space exists between said cylindrical portion and the membrane, wherein an amount may stagnate product. This amount of product may be more or less contaminated air, which is undesirable in terms of cosmetic, food or medical use. The cap described in this same earlier international application is not adaptable to any type of container, which is some discomfort in practice.
GB-A-214 548 discloses a sealing membrane to be stretched to be placed on a sealing surface with which it is intended to cooperate. This stretching leads to a significant manufacturing difficulty of the container.
WO 98/14387 discloses a cylindrical sealing membrane placed on a corresponding cylindrical sealing surface and held thereon by engagement of an integral annular projection of the diaphragm in a groove fitted in said sealing surface. In addition to mounting difficulties, tightness obtained does not appear perfect.
Furthermore, an existing container typically includes a screw cap which, if it provides good protection of the product inside the container, the other hand is relatively difficult to manufacture and handle. Other containers include swivel lids, easier to manufacture and handle that screw caps but does not provide perfect protection of the product inside the container with regard to air or dirt.
In addition, a container structure for containing two substances separately and allowing the mixture thereof at the time of use is known in itself. existing container structures, however, have some practical disadvantages related to either their production or in their use.
The present invention aims to provide a membrane sealing device of the aforementioned type, easy to manufacture, by means of a molding technique relatively uncomplicated and inexpensive to implement, for obtaining a perfect sealing, and adaptable to any type of container, in particular those comprising caps attached on their necks.
The invention also aims to effectively eliminate the risk of contamination by the ambient air or soil by foreign bodies, the amount of product that can stagnate between the product outlet from the container and that the valve form the membrane. The invention has the further object of providing a structure giving perfectly satisfaction, from the point of view of the manufacture of the container, in particular as regards the molding of the various parts constituting the container, from the point of view of ease of handling of the container by the user or wearer.
The device comprises, in known manner, a membrane valve consists of a portion forming the seat of this valve, wherein is provided a product flow conduit in the container, and by a membrane in elastically deformable material, closely engaged on this seat portion; This membrane, by its elastic deformation resulting from a pressure exerted on the product contained in the container, permits the flow of product between itself and the seat portion and, in the absence of such pressure, is pressed against this seat portion to block flow of the product and closing the container tightly.
- said seat portion has a generally conical shape, and has a cross section which increases in the direction of the product outlet opening beyond said valve; - said membrane has a generally conical shape corresponding to that of said seat portion, said shape being such that said membrane may be fitted tightly on the seat portion, and
- said membrane and said container comprise respective support means, cooperating with each other when the sealing device is mounted on the container to maintain the membrane in its narrow fitting position on said seat portion .
Thus, according to the invention, said seat assembly and said membrane portion can be performed independently from each other and then be connected to one another by press fitting to constitute the sealing device; said support means of the membrane relative to the container can then be used to ensure the axial immobilization of the diaphragm relative to the seat portion. The seat portion and the membrane can be manufactured by relatively conventional molding techniques and easy to implement, and the sealing device according to the invention is not dependent, as in the prior art, a tight engagement in the neck of the container.
The seat portion and the membrane are advantageously shaped to permit a slight circumferential stretching of the membrane on the seat portion in said tight fitting position.
This stretching circumferential allows to absorb possible dimensional variations of the respective seat portion and the membrane, resulting from manufacturing tolerances thereof.
Said support means can advantageously extend over the entire circumference of the membrane and be shaped to constitute a seal between the portion of the container forming the reservoir and the container neck and / or between this neck and a workpiece, such as a cap, that can receive the end of the container.
According to a preferred embodiment of the invention, the seat portion is molded with a part, in particular a hood, intended to be mounted, for example by snap-fitting, onto the neck of the container. Advantageously, in this case,
- the membrane comprises a flange coming to bear, during the establishment of said part onto the container, against a bearing surface provided in the container neck, and / or
- the membrane has a collar projecting radially outwardly shaped to be, during the establishment of said part onto the container, clamped between the neck and this coin.
Advantageously, the seat portion has a rib projecting from its wall, radially and outwardly therefrom, said rib being located between the conduit through which the product may be inserted between the seat portion and the membrane and conduit through which the product escapes from between the seat portion and the membrane to the outlet, the two orifices of the conduits located closest to each other being arranged near this rib.
Said rib thus cooperates with the membrane to form a linear seal clearly separated from the area between these two orifices, and this area is minimized. This seal forms an effective barrier against the introduction of a foreign body, and there is practically no product likely to stagnate between said orifices and thus may be contaminated by the ambient air.
Preferably the sealing device comprises a pivotable lid shaped to be normally biased in the closed position and to pivot to the open position only under the pressure of the product stream.
The complete lid sealing the container, in particular allows a perfect protection of the quantity of product located immediately behind the product outlet.
Advantageously, in this case, the lid comprises a tab shaped to come, in the closed position of the cover, bearing against a thickened portion of the membrane, and when the cover is pivoted in the open position, elastically deforming this thickened portion, so that the latter tends, by elastic return, to bring the lid in the closed position.
This thickened portion may in particular belong to the aforementioned means of support.
Said tab may comprise a notch engaging with a corresponding flange, for mounting of the lid, the arrival of this lug against said thickened part of the membrane ensuring the maintenance of this catch against this rim.
The lid may also include at least one deformable portion integrally molded therewith, which is configured to deform when the lid is brought into the open position and for tensioning, by elastic return, to normally bring it in the closed position the lid.
According to another aspect of the invention, the device comprises a cap defining a product flow conduit and a lid pivotally received on the cap to allow closing of the duct; the cap has a hole and includes an elastic material part located inside of it, facing the hole; the lid comprises a tab dimensioned to be engaged in this hole with an opportunity to play, this play allowing the mobility of said lid between its open and closed positions; the bracket further comprises a clean rib to be snapped behind an edge of the cover defining said hole in order to ensure the mounting of the cover on the cap; the assembly is shaped such that, when said rib is snap-fastened behind said edge, the tab deforms said resilient member so that the elastic return of this piece makes it possible to maintain the lid in its closed position and without the flexibility of this part will not obstruct the pivoting of the lid in the open position under the pressure of the product contained in the container.
The lid is thus normally maintained in the closed position, and pivots to the open position to permit flow of the product contained in the container. The result is a perfect product protection is ensured, and the device is simple and easy to manufacture and easy to assemble.
Preferably, the lid comprises, on the side opposite said tab, at least one deformable integrally molded part with it, while the cap comprises at least one corresponding wall against which the deformable part comes to slide when the cover is brought into position d 'opening ; said corresponding wall deforms said deformable portion, such that this deformation tends, by elastic return of the cover material, to bring it in the closed position the lid.
Advantageously, the cap comprises a recess for receiving the closed position the lid, said recess having dimensions corresponding to those of the cover and being shaped so that the outer face of the cover is located in the extension of the outer face of the cap when the lid is placed in said recess in the closed position.
The cover thus offers no outside socket may allow its uprising. Product protection is thereby further increased.
The cover advantageously has, on its outside and opposite said tab, a shaped zone so as not to exactly match the shape of the corresponding area of ​​the cap with which it engages when the lid is mounted on the cap. As a result, the cover is slightly elastically deformed when the lug is engaged in said cap the hole, and this deformation contributes to normally hold the lid in its closed position. According to another aspect of the invention, the container has a structure comprising a first container which contains a first substance, a second tank, which contains a second substance, and means for mixing of the substances at the time of use ; said first tank has a deformable structure enabling it, in the position of non-compression, containing said first substance, and in compression position, to expel the substance; said second reservoir comprises a lid ensuring its closure; the container structure comprises a central body to which are connected said first and second tanks, said second tank being pivotally mounted on said central body; the container structure comprises means in an angular position of the second reservoir relative to the central body, to act on said valve member to place said second tank in communication with said first reservoir; the container structure comprises means for compressing said first reservoir to expel the substance contained therein so as to pass, through the central body, in said second reservoir for mixing said first and second substances .
Placing the tanks in communication with each other therefore involves simply rotate said second tank with respect to said central body and to compress said first tank in order to cause passage of said first substance in said second reservoir.
The container structure thus formed is simple and easy to manufacture and assemble, and is easy to handle by the user or wearer.
According to a preferred embodiment of the invention, - the container structure comprises means for stalling said second tank with respect to the central body in an angular position; - the central body comprises a peripheral wall which has a fitted helical groove in its outer face and protrusions projecting into said groove or areas of local interruption of this groove;
- the container structure also comprises a control part engaged around said first reservoir; this control piece is provided with a clean background to press against said first reservoir in order to compress it, and thread portions adapted to cooperate with said groove to allow axial displacement of this part relative to said central body, screwing ; these mesh portions and said asperities or local interruptions of the groove are shaped so as to create a "hard point" enabling, below a torque threshold, to wedge pivotally said actuation member relative to said central body, and beyond this torque threshold, to allow the crossing of said bumps or local interruptions by said thread portions to permit screwing of said control member on said central body.
Prior to use of the container, said actuation member occupies a first axial position relative to said central body, wherein said mesh portions are in abutment against said local irregularities or interruptions, and stall the pivotal control member relative to this central body. The pivot drive of this control piece in one direction while said second reservoir is maintained causes pivoting of the central body relative to the second reservoir to the angular position establishing communication between the second reservoir to said first reservoir and the pivoting chock position of the second reservoir relative to the central body. This calibration makes it possible, if the pivot drive of the control member is continued, to achieve the crossing of said bumps or local interruptions by said thread portions, and thus screwing the control part on the central body, which carries compressing the first reservoir and therefore the passage of said first substance in said second reservoir.
The side opposite to said cover, said second tank may have a deformable structure consisting of a corrugated configuration which allows it to expand to allow the introduction in it of the substance contained in said first tank. In its expanded shape, said second reservoir may form a product application tip; a material ball can be formed at the end of the tip and is connected thereto by a frangible zone of material, this ball can be separated from said second reservoir when it is manually grasped and rotated on itself to tearing said material portion which connects it to the reservoir. For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the sealing device which it relates.
Figure 1 is a perspective view of a cap which is equipped with a membrane comprising, and a cover closing the opening of the cap; Figure 2 is a sectional view along its axis, and said cap and cover, this figure also showing the end of a container on which the cap is intended to be latched; Figure 3 is a perspective view of the cap from the outside; Figure 4 is a perspective view of the cap, on the inside; Figure 5 is a plan view of the lid, by the inner face thereof; Figure 6 is a view similar to Figure 2 after assembly, in flow position of the product contained in the container; Figure 7 is a view similar to Figure 6 in sealing position of the container; Figure 8 is a longitudinal sectional view of another container provided with said sealing device, in a position; Figure 9 is a view similar to Figure 8, in another position of the container, and Figure 10 is an enlarged view, in section, of a part that includes the container.
Figures 1 to 7 show a sealing device 1 for a container 2, to preserve the product contained in the container 2 from contact with ambient air or contamination by foreign matter from outside the container 2. this container can in particular be a "tube", that is to say a shell 3 whose one longitudinal end has a circular transverse wall 4 and a neck 5, and the other longitudinal end (not visible in the figures) is closed by pinching and joining the walls of the casing 3.
In the example shown, the container 2 comprises a cap 6, adapted to cover the neck 5 and to be snapped onto the latter by cooperation of annular projections 7, 8 respectively, and a cover 9 closing the cap 6 .
Furthermore, the container 2 comprises an inner flange 10 projecting from its wall at the base of the neck 5, surmounted by a conical range 1 1. The flange 1 0 1 comprises a circular wall 2 forming projecting upwards.
The device 1 comprises a valve diaphragm constituted by a pin 1 5 forming the seat of this valve and a membrane 1 6 elastically deformable material engaged closely on this pad 1 1 5. The pad 5 is secured to the wall of end 20 of the cap
6. It has an upper curved wall 21, an intermediate transverse web 22 and a lower curved wall 23. The wall 21 defines with the wall 20, an orifice 24 of exit of the product contained in the container 2 and with the disc 22 , an upper conduit 25 of flow of the product; the wall 23 defines with the disc 22, a lower duct 26 flow of the same product.
5 shows the pad 1 further comprises a rib 27 projecting from its wall, and radially outwardly thereof, in the disc 22.
This rib 27 extends over an equal angular portion of the pad 1 5 That duct 26 and thus separates the top orifice of the duct 26 of the lower orifice of the conduit 25.
This pad 1 5 has a generally conical shape and has a cross section which increases towards the orifice 24.
The cap 6 furthermore has a circular wall 28 and a hole 29 located on the side diametrically opposite to the orifice 24. The wall 28 protrudes from the inner face of the wall 20, and its inner surface has a slight inclination with respect to the axis of the cap 6.
The membrane 1 6 is molded in an elastically deformable material. It has a generally conical tubular shape corresponding to the outer shape of the pad 1 5. This shape is such that the membrane 1 6 may be closely fitted on the stud 1 5, being slightly stretched in the circumferential direction.
The membrane 1 6 includes a bead 30 at its end of smaller cross section and a flange 31 extended by a flange 32 at its end of greater cross section. The bead 30 has a circular groove 34 opening into its face 35 axial end, and an inclined side face 36. The groove 34 has a width less than the width of the wall 12 and is intended to receive this wall 1 2 during assembly of the cap 6, the membrane 1 and 6 of the container 2. This reception causes a radial deformation towards the outside of the bead 30, ensuring the perfect seal of the assembly. The faces 35 and 36 abut respectively against the flange 10 and the range 1 1 as well as be seen in FIGS 6 and 7. The collar 32 protrudes radially outwardly, and is shaped to be, during commissioning in place of the cap 6 of the receptacle 2, clamped between the neck 5 and the wall 28 of the cap 6.
The lid 9 has a tab 40 having a notch 41, the walls 42 adapted to engage in the duct 25 for guiding the pivoting of the cover 9, and inclined faces 43 capable of coming into abutment against the inner face of the wall 28 .
As shown more particularly in Figures 6 and 7, the tab 40 is intended to be engaged in the hole 29 and to bear against the bead 31, sinking slightly therein.
This recess keeps the notch 41 engages the corresponding edge of the cap 6 which delimits the hole 29.
The area 44 of the cover 9 next to the tab 40 is shaped so as not to exactly match the shape of the area of ​​the wall 20 with which it engages, so that the lid 9 is slightly deformed elastically when said tab 40 is engaged in the hole 29 and this deformation tends to normally hold the lid 9 in its closed position and that the cover 9 is pivoted in the open position only under the pressure of the product stream.
The above-mentioned depression of the lug 40 in the bead 31 allows the elastic deformation of the bead 31 upon movement of the cover 9 in the open position, which is, by elastic return, to bring the lid in the closed position.
The faces 43 slide against the inner face of the wall 28 when the same movement 9 in the open position lid but are shaped to slightly deform the walls 42 and the cover 9 in the same position, thus contributing to remind the lid 9 in the closed position.
In practice, the entire cap 6 - stud 1 5 on the one hand and the membrane 16 on the other hand can be performed independently then be assembled by press fitting to constitute the sealing device 1. The circumferential stretching of the membrane 6 and the rib 27 makes it possible to absorb any dimensional variations of the respective pad 1 5 and 1 6 of the membrane.
After mounting, the beads 30 and 31, the flange 32, the flange 10, the range 1 1, the neck 5 and the wall 28 constitute bearing means cooperating with each other to maintain the membrane 16 in narrow its fitting position on the pad 15. the same means are used to form two seals of the container 2. These seals are particularly effective, since the range 1 1 and the wall 28 tend to urge the beads 30 and 31, respectively, radially and inwardly.
A pressure exerted on the container 2 causes the product contained in the container to flow into the duct 26 until disc 22 and the rib 27. The latter cooperates with the membrane 1 6 to form a linear seal from substantially separate the area located between the upper orifices of the conduit 26 and lower conduit 25. This seal is an effective barrier against the introduction of any foreign body in the container 2. Moreover, said area is minimized and there is virtually no product likely to stagnate between said ports. The cover 9 allows the perfect protection of the quantity of product located immediately behind the orifice 24.
Figures 8 and 9 show another container 50 equipped with a device 1 identical to that described above. For simplicity, the same reference numbers as before are used to denote already described means. The container 50 has a structure enabling it to contain two substances separately and allowing the mixture thereof at the time of use.
This structure of container 50 includes a first reservoir 51, containing one of these substances, a second reservoir 52, containing any of these substances, a central body 53 which are connected to tanks 51 and 52, and a control part 54 can be screwed onto the body 53.
The tank 51 has a bellows structure enabling it, in the position of non-compression (Figure 8), to contain said substance, and in compression position (Figure 9), to expel the substance. It has a neck 5 to its locking on the body 53, and a conical range 1 1.
The reservoir 52 has a circular recess 55 shaped to enable its connection to the body 53 by snap-fastening, with the possibility of pivoting of the reservoir 52 relative to the body 53.
The tank 52 also includes a neck closed by a cap 56. This cap 56, seen more particularly in Figure 10, comprises a pad 60 connected to it by a material portion 61 thinned, the wafer 60 being provided with a tab 62 projecting, after assembly, beyond a curved wall 63 that includes the body 53, as is shown in Figure 8.
On its side close to the cover 56, the tank 52 has a bellows structure, dimensions, and number of identical folds in the bellows structure of the tank 51. This bellows structure allows the expansion of the container 52 to allow the introduction in it of the substance contained in the reservoir 51. The side opposite to the lid 56, the reservoir 52 forms a point 65 at the end of which is a material ball 66. This ball 66 is connected to the tip 65 by a frangible zone of material, and can be separated the reservoir 52 when it is manually grasped and rotated on itself to tear the material region. This separation allows the tank opening 52, and the tip 65 forms an applicator.
The body 53 includes a circular wall 70 in the outer face of which is fitted a helical groove. This groove is interrupted locally, in specific locations, to create a "hard point" as described below.
The body 53 also comprises a transverse web 71, which projects an end piece 72 for connection of the neck 5. This web 71 is secured to a pad 1 5 as mentioned above and an endpiece 72 for connecting the neck 5 of the tank 51. The web 71 also includes a wall 28 as mentioned above for the clamping of the flange 32 between this wall 28 and the neck 5.
The piece 54 has a tubular shape closed by a bottom at one end and is engaged around the tank 51. On the side opposite said bottom, it comprises portions 75 of net, adapted to cooperate with the groove of the wall 70 to permit axial displacement of the part 54 between the axial positions shown respectively in Figures 8 and 9. In the position shown in Figure 8, these portions 75 are abutted against said local interruptions of the groove. These thread portions 75 and said local interruptions of the groove are shaped so as to create said "hard point", allowing, below a torque threshold, stalling pivoting the workpiece 54 relative to the body 53, and -delà of the torque threshold, to allow the crossing of said local interruptions by said thread portions 75 to allow the screwing of the part 54 of the body 53.
In practice, to carry out the mixing of the substances contained in the reservoirs 51 and 52, the piece 54 is gripped by one hand while the other hand grasps the reservoir 52. This part 54 is pivotally driven in one direction while the tank 52 is maintained or is pivoted in the opposite direction. Said abutment position of the portions 75 against said interruptions of the groove that the reservoir 52 is pivoted to the body 53 until the tab 62 bears against the wall 63 then crosses said wall, which tears the thinned area 61 and thus opens the container 52. the tab 62 is then retained by the wall 63, which keeps the aperture thus created next to the flow duct delimited by the wall 63 and the wall 21, and securely hold the container 52 by relative to the body 53.
This calibration and further the drive exerted on the part 54 then allow said portions 75 to cross said interruptions of the groove of the body 53, which allows the screwing of the part 54 relative to the body 53. This enables screw compressing the reservoir 51 and thereby force the passage of the substance contained in the reservoir 51 through the valve constituted by the membrane 1 6 and the web 22. the tank of substance stream 51 to the tank 52 causes an expansion the reservoir 52 correspondingly to the compression of the reservoir 51.
The ball 66 is then withdrawn to open the container for application of the product obtained by mixing said substances.
As is apparent from the above description, the invention provides a sealing device with many advantages over the prior art devices counterparts, particularly those to be easy to manufacture, by molding techniques relatively uncomplicated and inexpensive to implement, allowing to obtain a perfect seal, and being adaptable to any type of container.
The invention also provides a container structure giving perfectly satisfactory, from the point of view of the manufacturing of the container from the point of view of ease of handling of the container by the user or the user. It goes without saying that the invention is not limited to the embodiment described above as an example but that it encompasses all the variants. Thus, the piece 54 could be omitted, the pressure on the reservoir 51 can then be applied directly.
