Description: ARRANGEMENT IN AEROSOL CONTAINERS Technical field: The present invention relates to an arrangement in aerosol containers for prevention of unnecessary spreading of goods outside the container. The arrangement thus comprises a holder for a body, whereby the holder is arranged with or connectable to a container. A first end portion of the body is intended to be arranged adjacent to an orifice, valve steam, emptying device, discharge nozzel or the like of the container. The body is arranged so that it can be actuated by an exterior means for actuation on the container's discharge nozzel. Background: There is a need for an arrangement which prevents unnecessary spreading of goods from aerosol containers. Moreover, there is a need in the case of such containers to be able to utilize the goods in an improved manner and thus reduce the consumption of goods. There is also a need for such arrangements which can be arranged to a container or which can form such an arrangement or a separate arrangement which can be connected for use with aerosol containers and thus for different types or designs of aerosol containers. Technical problems: The goods in aerosol containers or other similar spray containers are discharged via the actuation of a valve, whereby the goods in the form of a cloud spread to a relatively wide extent round the container, and which may also be inhaled by the person handling the container, and only in part be utilized for the intended purpose. If the container contains, or the goods comprise, dangerous or injurious substances it is even more import¬ ant to limit the spreading of the goods. In known aerosol containers the emptying devices is in the form of a valve. They also exist as dispensing caps for the actuation or emptying of the container, which caps are secured to the container, and therein in such a manner that they cannot be removed from the container for use on another container but are scrapped together with the container. During, for example, argon arc welding a so-called welding spray is used which is contained in an aerosol container. The welding spray is used to prevent welding splash from fastening on the spray-nozzel, the contact pipe and gas sleeve on the welding gun; and also to apply the medium directly on the welding area to prevent welding splash from fastening on painted surfaces or the like in the vacinity of the welding area. In the first mentioned case the medium is supplied directly into the gas sleeve but with the containers used today it is not possible to prevent the spreading of a gas cloud, with the result that the operator receives a shower of the medium in the face when it is necessary to bring the face close to the application area in order to perform the operation or re- filling. The situation is similar in the second mentioned case or when the application of the medium takes place directly on the welding object or welding area. Such mediums contain methylene chloride (dichloromethane), which is injurious to health and most dangerous to inhale. The solution: By means of the arrangement in accordance with the present invention it is possible to comply with the requirements made and also eliminate said disadvantages of existing devices. It is thus possible to limit the port¬ ioning of the goods to the object which shall be injected or supplied with the goods without any spreading of the goods taking place. Further, a con¬ siderable reduction of the consumption of the goods and medium is achieved. One arrangement can be used for a variety of containers and with containers of different designs, and the arrangement is adaptable for different app¬ lications and to different designs at the place of application or object which is to be injected with or supplied with the goods or medium in quest¬ ion. The arrangement is thus characterized wherein, that it comprises a holder showing a sleeve, in which the body is intended to be displaceably arranged and that a second end portion of the body is arranged for direct actuation of said means for actuation of the container's discharge nozzel or the like, whereby the means comprises or forms a reception of supply point for the container's goods. Another characteristic of the arrangement according to the invention is comprised by the fact that said holder comprises a connecting part to the container, and comprises also said sleeve, whereby the connecting part and the sleeve are arranged in such a way that the position of the sleeve in an axial direction is adjustable in relation to the holder's connecting part. In accordance with another characteristic of the arrangement according to the invention the body is replaceably arranged in the arrangement and can in applicable cases be replaced with a second body, which, in said second end portion, shows an adapted design with the reception or supply point of said means. According to one more characteristic of the arrangement according to the invention a first end portion of the sleeve is arranged for connection to the container. One more characteristic of the arrangement according to the invention is that a second end portion of the holder or the sleeve shows an inwardly directed or towards the body directed flange edge. The arrangement according to the invention is arranged for arrangement on an intended container showing a collar. In this case one characteristic of the arrangement according to the invention is that the body and the sleeve together form an annular groove or the like, which is limited by the body's envelope surface and the sleeve's side turned towards the body in its first end portion, which groove or the like is arranged to take up at least a part of the collar or the like in the container. According to one characteristic of the arrangement according to the invent¬ ion said first end portion of the body shows a centrally located recess. When the aerosol container shows a centrally located shoulder on its upper side one characteristic of the arrangement according to the invention is that said recess of the body takes up at least a part of the shoulder in the container, whereby the bottom of the recess is arranged at a distance from the shoulder. When the arrangement is arranged on an intended container the arrangement according to the invention is thus characterized in that the body shows a channel, which takes up at least a part of or at least the end portion of the discharge nozzel or the like in the container. One more characteristic of the arrangement according to the invention is that the holder or the connecting part of the holder is designed as a cover, which is intended to be arranged on the container and connect the arrangement to the container. One characteristic of the arrangement according to the invention is co - prised by the fact that the holder or its connecting part is designed with an opening or a hole, in which the sleeve is " arrangeable with slid¬ ing fit or slack sliding fit. Yet another characteristic of the arrangement according to the invention is comprised by the fact that a body is arranged to be able to be arranged in another arrangement of the type in question or in another sleeve and in applicable cases that a body and/or a sleeve is arranged to be able to be arranged in another arrangement of the type in question or in another connecting part. Brief description of the drawings: Further characteristics of and advantages with the arrangement in accord¬ ance with the invention will be apparent by embodiments in the following description of the invention, whereby a simultaneous reference will be made to the accompanying schematic drawings, in which Fig. 1 shows in cross section an example of an embodiment of the arrangement according to the invention, Fig. 2 shows partly in cross section a second embodiment of the arrangement according to the invention in an operative position and arranged on a container, Fig. 3 shows in cross section a part of the arrangement as per Fig. 2, Fig. 4 shows in cross section a part which can be included in the arrangement according to the invention and comprising a cover, Fig. 5 shows in cross section a second embodiment of a first part of the arrangement according to the invention, Fig. 6 shows a cross section through a second part, which can be included in an arrangement according to the invention, Fig. 7 shows a cross section through a third part, which can be included in an arrangement according to the invention or a second embodiment of the part, which is shown in Fig. 4 and which comprises a cover and Fig. 8 shows in cross section a third embodiment of the arrange¬ ment according to the invention. Best mode for carrying out the invention: With reference designation 1 in Fig. 1 is thus shown an arrangement in accordance with the invention according to an embodiment. The arrangement shows a sleeve 5 and a body 3, which is intended to be detachably or mov- ably arranged in the sleeve 5. The sleeve 5 or the arrangement 1 can be arranged in a cover or arranged secured or in one piece with a cover, which is adapted so that it can be arranged as a cover or a protective casing on a container 6, which contains an agent, for example a welding gas, see also Fig. 2. Such containers 6 show an opening often provided with a discharge nozzel 9, which also actuates or functions as a valve for the pressurized goods in the container 6. The top part, around the discharge opening for the medium, in the container 6 is shaped in a special way, that is with a raised middle part 26, in which the opening or nozzel 9 is located, and a surrounding collar, flange or the like at a distance from this middle part, see designation 11 in Fig. 2. In order to be able to portion the goods in the container 6 an actuation is required on the container's valve or an actuation via a nozzel 9, whereby the medium is discharged from the con¬ tainer with the aid of pressure gas. In order that an arrangement in accordance with the invention will achieve a guiding and reasonably ' stable fit in or ' to the container the arrange- ment's 1 lower part shows an adapted design with the container's 6 top part. Thus, the sleeve 5 can show a groove 12 and the body 3 a recess 13, while the body's 3 end portion thus shows a collar 14, flange or the like. By such a design it is possible according to the embodiment for the sleeve to flange the container's 6 collar 11 and the body's 3 collar 14 to be entered in the annular groove 30 or the like, which is created in the container 6 between its said collar 11 and its middle part. The body's recess 13 flanges in turn the container's 6 middle part but shows a depth such that it lies free from said middle part in at least a displaced position in the sleeve 5. The sleeve 5 shows at one end a flange edge 16 directed inwards to its opening, which is intended to comprise an end-stop for the body 3. The body in turn shows an end portion 15 in the form of an annular edge or point and a recess 17 or chamber, in the bottom of which an orifice 18 is arranged, possibly shaped as a valve. Through the body 3 a channel 19 leads from the orifice 18, whereby the channel opens into the body's 3 recess 13. The channel 19 or its opening portion or towards the opening turned part, shows preferably a design, which is adapted to accomodate at least a part of a nozzel 9 in the container or is arranged to be able to contain such a nozzel in those cases where the container lacks a nozzel. The body's 3 envelope area does not need to show any particular surface fineness but only needs to be adapted so that it can be displaced in the sleeve. Via the container's 6 goods lubrication can be achieved, in the case for example of welding medium which contains oil. The arrangement can be used for several containers 6, which are often provided with a cover. As a support, fixing arrangement in the container, a cover, etc. , the sleeve 5 can with the body 3 be arranged to a similar cover, such as the traditional covers, whereby this function is maintained also during the use of the arrangement according to the invention. An example of such a cover is shown in Fig. 1 but also in Fig. 4 and therein separate. The cover 4 does not deviate in design from the standard covers in such containers except that it shows a recess 8 or an opening for the sleeve 5. The cover can also be dimensioned somewhat larger and show a thicker size to be able to cope with the extra strain in the handling and use of the arrangement, and also with respect to the longer period of use of the arrangement in comparison with a customary cover, which is a dis¬ posable product and is scrapped with the container when the goods is empty. The cover 4 shows in the standard manner an edge portion 7 in a collar for connection to the container 6 via for example clipping around a container showing a circular rib. As indicated in Fig. 7 the cover 4 or the connecting part can be shaped with a collar 27, in which the sleeve 5 should be arranged and entered with sliding fit or slack sliding fit, so that the sleeve 5 can be adjusted in the axial direction of the connecting part 4 by means of displacement in one of the axial directions. Thus, the arrangement 1 comprises a holder 2 for the body 3, whereby the holder includes a connecting part 4 formed in one piece or in separate parts for connection to an aerosol container 6 and a sleeve 5, in which the body 3 should be located and during external actuation of an object 10 or the like be displaceable towards the operation of the valve or discharge nozzel 9 or to the spring organ belonging to this. The fact that the sleeve 5 is displaceable enables the body 3 to achieve a determined position in the arrangement 1 in relation to the container 6 or its discharge opening 9 or nozzel, that is the body's end portion 21 must be located at a certain distance from the container or its centrally located shoulder or nozzel in order that it can be displaced for the open¬ ing of the valve and portioning or emptying of goods from the container 6 at the same time as the end portion 21 shows a protruding flange for guid- ing, or as a support for, the body 3, and which flange should be taken up by an annular recess or groove in the container 6. In Fig. 5 is shown a second embodiment of the body 3, which shows a first end portion 21 with a recess 25 for the formation of a groove together with the inside of the sleeve 5 in its first end portion 23, a collar 14, flange or the like, which is intended for the guiding in the container 6 and which limits an end surface of the body, in which an inlet for a channel 19 is arranged and which channel 19 opens in a recess 17 or a chamber and therewith in an orifice 18. The collar 14 further limits the recess 13. In the body's 3 second end portion 22 an annular end portion is designed 15, which can be shaped or is adapted for connection or sealed- connection to the object 10, which is to be supplied with goods or the medium in question. A recess 29 or an edge portion 29 is designed for the taking up of the sleeve's 5 inward directed edge flange 16, whereby the end portion 15 can obtain a close connection to the object 10. The body 3 can be shaped with different or adapted forms, particularly with respect to its second end portion 22 or its end portion 15 in order to fit different entry or discharge points. Thus, several bodies 3 can show one and the same design and dimension but show different diameters on the end portion 15 and/or different forms on the end portion 15 for connection to the object 10. The sleeve 5 can be formed as a straight sleeve with an adapted shape in its first end portion 23 for the fitting, engagement or support to the container 6. The sleeve 5 should thus have a fixed support from the con¬ tainer 6, which fulfills an intended function and required position for the body 3. Thus, the sleeve 5 can also be shaped in different lengths in order to fit its own and the body's 3 intended position on connection to a container 6. The sleeve's 5 second end portion 24 also shows as earlier - which also applies to the above description of the shape of the body according to a second embodiment - an inwardly directed edge or stop flange 16 for the retention and limiting of the movement of the body 3 in the sleeve 5. The embodiment also shows that the sleeve's 5 inside can be shaped with axially localized ribs, bulges 28 or the like, through which the body 3 receives a lesser fitting or friction surface to the sleeve 5 and can slide or be displaced more easily and with the elimination of any risk for jamming or the like. The cover 4 or the connecting part 4 according to Fig. 7 thus shows a flange or a collar 27 for improved holding of the sleeve 5 and a more satisfactory guiding and slack gliding or displacement fit in the connect¬ ing part 4. The connecting part 4 is otherwise adapted in its design to fit containers 6 and be able to be connected to these or that the connect¬ ing part is included as a part in a container 6. During the use of the arrangement 1 according to the invention, for example for the refilling of mediums to a device 10, the container 6 is brought with the arrangement to the refilling point of said device, which with the aid of a part or the material is brought to affect the body 3 to displace the body 3 towards the container 6 or its opening or nozzel 9, see the arrow 20 in Fig. 2. The body 3 thus actuates the container's open¬ ing, orifice, valve steam, nozzel 9 or the like so that the goods in the container 6 flow out through its opening and through the body's 3 channel 19 and orifice or valve 18 and further through its recess, chamber or the like to the intended refilling or application point. A directed portioning is thus achieved and also a protection against the spreading of the goods outside the arrangement, or the arrangement or the organ which is to be supplied with the medium in question. Without exceeding the scope of the concept of the invention modifications of the arrangement shown and described in the embodiments should be possible. The arrangement according to the invention is thus not restricted to what has been shown and described but only to the following claims.
