Title: Container and dispensing system having the container

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This is a continuation application, under 35 U.S.C. § 120, of copending International Application PCT/AT2014/000223, filed Dec. 15, 2014, which designated the United States; this application also claims the priority, under 35 U.S.C. § 119, of Austrian Patent Application A 976/2013, filed Dec. 20, 2013; the prior applications are herewith incorporated by reference in their entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The invention relates to a container including a connection having an opening, a closure removable by displacement of the container in a slide direction, and at least one guide element which is provided on the connection and at or in which the closure is slidable relative to the container. The invention also relates to a dispensing system for a flowable product, including at least one dispenser provided with a container mounting and at least one container containing the flowable product. 
     A container and a dispensing system of that kind are described for example in International Publication WO 95/09111, corresponding to U.S. Pat. No. 5,730,694 or International Publication WO 2008/089500, corresponding to U.S. Pat. No. 8,561,844. The dispenser serves for dispensing liquid or creamy products, in particular in the sanitary and hygiene area such as for example soaps, disinfectants, creams and so forth. 
     A container can be fitted into a dispenser if the region of the container, that surrounds the opening, is compatible with the container mounting of the dispenser. That is thus a prerequisite for being able to use the container at all, but it has the disadvantage that all containers of the same configuration or at least all containers with regions of the same configuration around the opening can be used without a container having the wrong contents being noticeable. That matching relationship is also referred to as coding, in which respect various degrees of coding can be established, which involve the number of the cooperating coding elements. 
     The container described in the state of the art has a container neck or connection, from which a respective limb of a sliding guide projects at both sides parallel to the end face, and on to which a clip-like C-shaped part which engages behind the limbs is pushed as the closure. Therefore the container mounting on the dispenser is of the same configuration as the closure, that is to say the limbs projecting from the connection have the container mounting engaging therebehind. That makes changing the container easier since a new container can be fitted to and inserted into the container mounting without the closure having to be previously removed. That is advantageous in particular since the container is fitted upside down because the content cannot flow out of same or no additional measures are necessary to prevent that. As soon as the closure bears against the container mounting, the container can be slid and the limbs of the connection slide in grooves of the container mounting, in which case finally the closure is released and lies loose in front of the container mounting. 
     SUMMARY OF THE INVENTION 
     It is accordingly an object of the invention to provide a container and a dispensing system having the container, which overcome the hereinafore-mentioned disadvantages of the heretofore-known devices of this general type and which have a sliding closure and codings which extend beyond an engagement of sliding guide elements in order to prevent an insertion of incorrect containers, since it is desirable or even necessary to only fill certain dispensers with certain containers. 
     With the foregoing and other objects in view there is provided, in accordance with the invention, a container having an opening provided on a connection and a closure removable by displacement of the container in a slide direction, wherein provided on the connection is at least one guide element, at or in which the closure is slidable relative to the container, and at the side of the container having the connection, there is provided at least one projection which projects forwardly in the slide direction and/or at least one forwardly open socket. 
     A recess or projection in a corresponding relationship therewith is provided on the container mounting respectively corresponding to the projection or to the socket at the side of the container that is provided with the connection. Therefore, upon insertion of the container, the projection and recess or the socket and projection engage into each other. 
     It is only in that way that the openings in the connection of the container and the container mounting of the dispenser come into alignment so that the content can flow out into the dispenser. Without a possibility of mutual engagement it would only be possible for the container to be pushed into the container mounting over a short length, in which respect that can be recognized by virtue of the fact that the container does not begin to empty and the closure is still hanging on the connection since it has also been pushed out only over the above-mentioned excessively short length. 
     Projections or sockets are possible at any suitable location on the side of the container that is provided with the connection, preferably in that respect it is provided that at least one projection and/or at least one socket are provided on the connection. 
     If the connection has limbs projecting at both sides as guide elements, a preferred configuration provides that one of the two limbs is shortened, thereby providing the socket. 
     Depending on the respective size and nature of the socket it may be advantageous for at least one tab which is attached to the connection by way of an intended breaking location to be broken off to form the socket, for example to provide a precise container coding after filling with the medium. 
     If only one socket is provided on the container then it is not possible for the container to be turned through 180°. That can be important if for example writing on the inserted container is to be readable. If in contrast a specific position of the container in the dispenser mounting is unimportant then two sockets turned through 180° can be provided in the connection. Insertion of the container is simplified thereby. 
     If the container and the connection are square then the container can also be provided with four projecting limbs or four sockets. It is also possible to conceive of placing the coding elements in various planes parallel to the slide direction of the container, particularly in mutually superposed relationship, thereby substantially increasing the possible coding combinations. 
     As mentioned the configuration of projections and sockets is not limited to the connection. In a further preferred embodiment therefore there are provided at least one projection and/or at least one socket at least at one upstanding limb of a U-shaped reinforcing plate of the container, that carries the connection and embraces the container at oppositely disposed edges. If the limb of the reinforcing plate extends perpendicularly to the slide direction a socket is preferably in the form of a hole in the limb. 
     A further preferred embodiment provides that the guide elements, the recess and/or the projection of the container mounting are provided on an exchangeable insert portion which is held in a cover plate of the lower part of the dispenser. 
     The substantial components of the dispenser therefore remain the same, irrespective of whether the projection and/or the socket in the connection are provided centrally or off-center as the container mounting which fits the container can be selected and fitted into the cover plate. The container mounting is raised in relation to the region of the cover plate in front thereof, by the thickness of the closure, in order to be able to insert the container connection into the container mounting without impediment. The container mounting is additionally preferably provided with a bevel at the front end to correct inaccuracies. 
     A further preferred configuration provides that a substantially L-shaped path is defined for insertion of the container into the dispenser, the first path portion of that L-shaped path extending perpendicularly to the slide direction and ending in particular in a depression in the cover plate in front of the container mounting. In that case, there are two conceivable options for the first path portion. In a first variant the L-shape extends overall parallel to the plane of the container opening so that the closed container can firstly be fitted laterally to the dispenser and can be displaced in front of the container mounting and is then pushed in the slide direction, in which case the connection slides into the container mounting and the closure remains disposed in front of same. If it is blocked not only in the slide direction of the container but also in opposite relationship thereto on the cover plate then when changing a container the closure is displaced on to the connection again so that the container which is now closed again can be pushed out laterally. 
     In the second variant the first path portion extends from above downwardly, in particular vertically or inclined rearwardly. 
     In both cases the location in front of the container mounting represents a form-locking deposit device for the closure, which is aligned with the container mounting. 
     The cover plate preferably represents an upper cover of a collecting chamber for the product to be dispensed, for example an intermediate chamber, a pump inlet chamber or the like. Therefore at least one projection is preferably of such a configuration that a hole into the collecting chamber is opened by removal of the projection, for example in order to insert a non-correlating container, and the dispenser thereby loses sealing integrity. 
     In addition an embodiment is conceivable in which, in a socket in the connection of the container, there is provided a barrier to the through-flow of the medium, and that barrier is opened only when a corresponding projection of the container mounting can penetrate sufficiently into that socket. 
     Other features which are considered as characteristic for the invention are set forth in the appended claims. 
     Although the invention is illustrated and described herein as embodied in a container and a dispensing system having the container, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims. 
     The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the figures of the drawings in detail and first, particularly, to  FIG. 1  thereof, there is seen a container  1  formed of soft flexible material, for example thin plastic film, which is approximately cuboidal and has an opening  3  formed in a wall provided in particular with a reinforcing plate  13 , in which the opening  3  is provided within a sealingly closable connection  2  or container neck. As  FIG. 1  shows the reinforcing plate  13  extends over a large part of the area of the wall and with side limbs  14  embraces two oppositely disposed edges of the container  1 . Details about such a container  1  and its manufacture are to be found in the above-mentioned International Publication WO 2008/089500, corresponding to U.S. Pat. No. 8,561,844. 
     The container  1  is intended in particular to receive liquid products like disinfectant, shampoo, soap or the like and, as shown in  FIG. 19 or 25 , is fitted upside down into a dispenser  20  so that the wall provided with the reinforcing plate  13  and the connection  2  forms the support side or the container bottom. 
     As shown in detail in  FIG. 2  the connection  2  carries a guide element  4  in the form of limbs  5  projecting at both sides as a prolongation of its end face, and a sealing ring  7  projecting slightly from the end face. A closure  10  is in the form of an approximately clip-shaped or C-shaped body which is pushed on from the side, in which case it engages behind the limbs  5  with guide elements  11 . 
     The configuration of a sliding guide on the connection  2 , that embraces the guide elements  4 ,  11 , simplifies insertion of the container  1  into the dispenser  20 , of which further  FIGS. 3, 4, 6 through 10 and 12 through 16  respectively only show the single element that is important in that respect, namely the container mounting  40  on the cover plate  21  of the lower portion. The cover plate has an opening  46  which, when the container  1  is inserted and sealed by the sealing ring  7 , aligns with the connection  2  and the opening  3  of the container  1  ( FIGS. 4, 8, 14 ). As can be seen from the view in  FIG. 3  the container mounting  40  on the cover plate  20  is of the same structure in regard to the guide elements as the closure  10  and can therefore also engage with its guide elements  41  behind the limbs  5  of the connection  2  when the container  1  is inserted into the container mounting  40 . That is indicated in  FIG. 6  showing the contour of the closure  10  in broken lines. The container  1  is therefore applied with the closure  10  to the container mounting  40  in front of the guide device elements  41  and is then inserted by way of a bevel  45  in the direction of an arrow A, in which case the closure  10  becomes free and remains disposed at the application point, as shown in  FIG. 7 . 
     In order now to ensure that only suitable containers or containers with suitable contents can be fitted into the dispenser, there is provided a coding, that is to say the container and the container mounting must be provided with mutually matching elements. In particular therefore at least one projection  42  is provided at the container mounting  40  and at least one corresponding socket  6 ,  6 ′ ( FIGS. 5, 11 and 17 ) is provided at or in the connection  2  of each corresponding container  1 , the projection and the socket respectively extending in the slide direction (arrow A) of the container  1 . If the correct container is inserted then, as can be clearly seen from  FIGS. 4, 8 and 14 , the openings  3  and  46  are aligned. The depth of insertion is limited by the depth of the socket  6  and the length of the projection  42  and by a transverse limb  44  on the container mounting  40 .  FIG. 5  shows the upper region of a container  1  with a connection  2  in which there is provided a central socket  6  into which the central projection  42  shown in  FIG. 6  engages. The cross-sections and lengths of the socket  6  and the projection  42  are the same. The inserted position in which the openings  5  and  46  are aligned can be clearly seen in the section in  FIG. 8 . The provision of a single central socket  6  is advantageous if only one installation position of the container  1  is wanted. If the aim is that the container  1  can also be inserted turned through 180° then a second central socket  6 ′ is also provided in the connection  2 , which is turned through 180° relative to the first, that is to say it is in diametrally opposite relationship, as shown in  FIGS. 7 and 9 . In cross-section therefore the connection  2  is of an H-shape. Like each socket  6 ,  6 ′ in this embodiment the projection  42  has a cross-sectional area which is composed of a rectangle with an adjoined triangle. If in spite of two mutually oppositely disposed sockets  6 ,  6 ′ only one installation position is to be allowed for the container  1  in the dispenser, the closure  10  which is suited thereto can have a projection which fits into the second socket  6 ′ so that the closure  10  can be opened only towards that side. 
       FIG. 11  shows the upper region of a second embodiment of a container  1 . In this variant the socket  6  is provided not centrally but laterally, and therefore a corner region of the connection  2  is missing. In this case too, a second socket  6 ′ is preferably turned through 180°, as can be seen from  FIG. 13 . 
       FIG. 12  shows the associated container mounting  40  in which the projection  42  is also provided off-center in the corner region. The socket  6  and the projection  42  in this embodiment are of a trapezoidal cross-sectional area.  FIG. 13  shows a horizontal section through the connection  2  of the container  1  fitted into the container mounting, in which case by virtue of the socket  6  the connection  2  can be inserted as far as the abutment  44  so that the openings  3 ,  46  are aligned. That is again visible in the section in  FIG. 14 . 
     The insertion of an incorrect conventional container corresponding to  FIGS. 9 and 15  without a socket is practically out of the question since, as  FIGS. 10 and 16  show, it can admittedly be inserted over a short distance, but the openings  3  and  46  are so displaced that no through-flow is achieved. 
     In the two embodiments shown in  FIGS. 5 and 11  the sockets  6 ,  6 ′ are provided on the connection  2  below the limbs  5  of the sliding guide, which thus extend over the entire depth or length. In the  FIG. 17  embodiment the socket  6  extends over the entire height of the connection  2  so that one of the two limbs  5  is shortened. Since more than half of the limb remains, neither the sealed seat of the closure  10  on the connection  2  nor the seat of the connection  2  in the container mounting  40 , is adversely affected. 
     As  FIG. 18  shows it is also conceivable for the socket  6  to be produced by breaking off at least one tab  9  which is held to the connection  2  by way of intended breaking lines  8 . 
     In order to only be able to later establish the different coding options upon manufacture of the dispenser, the projection  42 , the guide elements  41  and the transverse limb  44  are advantageously provided on an insert portion  43  which can be disposed in matching relationship with the containers to be used with that dispenser, in the cover plate  21  of the lower portion of the container  1 . 
     The above-described embodiments afford protection in particular against the insertion of conventional containers of different manufacturers since the projection in the container mounting device requires recesses and sockets on the container, which as far as possible cannot be subsequently provided. 
     Reversal of the elements, namely a socket or a recess in the container mounting and a corresponding projection on the connection also represents a coding option in relation to a sliding closure. Such a configuration is desirable in particular when it is only a confusion of products from the same manufacturer, which in particular are not to be mixed up, that is to be excluded, since a conventional container without projection also fits into the container mounting. Such an embodiment is not shown in the figures. Rather,  FIGS. 20 through 22  show a hybrid form in which projections and sockets are provided both on the container  1  and also on the container mounting  40 . 
     The container  1  (indicated in  FIG. 22 ) again has a reinforcing plate  13  which with the oppositely disposed limbs  14  embraces two container edges. Each limb  14  has between one and six holes which form sockets  6  belonging to the container  1  and into which between one and six projections  42  can pass upon insertion of the container  1  into the container mounting  40  or its insert portion  43 . 
     In accordance with the rules of combinatorics it is possible to derive therefrom a relatively large number of possible options, each of which is then associated with a given product.  FIG. 20  shows for example two such projections  42 . 
       FIGS. 20 through 22  further also show projections  12  in the form of limbs which project from connections  2  in the slide direction (arrow A) and penetrate into a corresponding orientation or socket  6  or a corresponding recess on the container mounting  40  when the container  1  is inserted. In addition disposed on the reinforcing plate  13  are limbs  15  which extend in the slide direction approximately over the second half of the slide travel distance until they come to bear against the projection, which is visible in  FIGS. 21 and 22 , of the inset portion  43 , in the form of an abutment  47 . In that end position the connection  2  bears against the transverse limb  44  while the projection  12  has passed into the socket  6  and the opening  3  aligns with the opening  46  (not shown in these figures) in the container mounting  40 . The abutment  47  is provided only at the left-hand side in the drawing and the second limb  15  provided at the right-hand side of the connection  2  does not impede insertion since an abutment  47  is missing at that side and a recess is thus also provided there. A container mounting  40  with an insert portion  43  as shown in  FIGS. 20 through 22  prevents the insertion of conventional containers only by the projections  42  and the socket  6  in the region of the upstanding limbs  14  since no projections are provided, which require sockets on or in the connection  2 . Abutments  47  on the insert portion  43  or on the container mounting  40  itself as well as limbs  12  or  15  on the connection and the reinforcing plate  13  serve primarily to associate given products with given dispensers. 
       FIG. 23  shows a perspective view of a second embodiment of a container  1 , on to the connection  2  of which there is pushed a closure  10  provided with a coding. The closure  10  shown in a number of configurations in  FIGS. 23 through 34 , as in the embodiments shown in  FIGS. 1 through 22 , includes an approximately C-shaped body with limbs  11  which engage behind limbs  5  on the connection  2  and has a top side  19  parallel to the plane of the container opening  3 , two side surfaces  17  disposed in the slide direction (arrow A) of the container  1  and two side surfaces  18  perpendicular thereto. 
       FIGS. 23 through 30  show closures  10  which in at least one of the two side surfaces  17 , have a recess  16  serving as coding in the form of a groove. In  FIGS. 23 through 29  the groove  16  extends perpendicularly to the plane of the container opening  3  while in  FIG. 30  it extends inclined forwardly. As can be seen from  FIG. 24  the depth of the groove preferably corresponds to the wall thickness so that the limb  5  of the connection  2  is exposed or is not cut out. It is possible to see corresponding projections  24  in the form of noses or limbs on the dispenser immediately in front of the container mounting  40  as counterpart elements in relation to the recess  16 . As can be seen from  FIG. 25  the region of the cover  21  of the lower portion of the dispenser  20  is provided with a depression into which two projections  24  project. A container  1  as shown in  FIG. 23  can now be introduced into the position in front of the container mounting  40  either horizontally from the side ( FIG. 27 ), vertically from above ( FIGS. 28 and 29 ) or inclined from above ( FIG. 30 ). That signifies an at least approximately or precisely L-shaped travel path shown by two arrows B and A. 
     In  FIG. 27  the L-shaped path is parallel to the plane of the container opening  3  and to the plane of the opening  46  of the container mounting  40  and the closure  10  shown in  FIG. 27 . The container, which is not shown for the sake of clarity, moves over the first path portion corresponding to the arrow B into the chamber forming the deposit device  23  in front of the container mounting  40 , in which case the projection  24  passes into the recess  16  when the two coding elements are identical. The deposit device  23  is deeper than the container mounting  40  by the thickness of the top side of the closure  10  so that the container can be further displaced in the direction of the arrow A, wherein the closure  10  remains disposed in the deposit device  23  and the medium contained in the container  1  can flow away through the openings  3  and  46  into the lower portion of the dispenser  20 . 
     The deposit device  23  is defined by limbs  22  so that it receives the closure  10  in a form-locking relationship. As a result the container  1  is moved on to the closure  10  again upon removal in opposite relationship to the slide direction (arrow A) and is then removed in a condition of again being closed in opposite relationship to the arrow B from the dispenser. The container  1  can therefore also be exchanged while still partly filled without a partial quantity of its contents being lost. 
     Referring to  FIG. 28  the closed containers are lowered vertically from above (arrow B) and the closure  10  is again in the deposit device  23 , as shown in  FIG. 29 , and the container can then be inserted into the container mounting  40  (arrow A). 
       FIG. 30  shows the inclined configuration of the coding elements  16  and  24  and thus also the inclined direction (arrow B) of insertion into the deposit device  23 . The second part of the travel path is again indicated by the arrow A into the container mounting  40 . 
       FIGS. 27, 28 and 30  each show a perspective view illustrating the lower portion of a dispenser  20  with the cover plate  21  on which the container mounting  40  and an insert portion  43  corresponding to  FIGS. 20 through 22  is provided. The only difference is the transverse limb  44  which is continuous over the width so that the container to be used in this case is without projections. Likewise, the abutment  47  is missing, in comparison with the configuration shown in  FIGS. 20 through 22 . 
       FIGS. 31 and 32  show a closure  10  on which recesses  16  are provided in the narrow side surfaces  18 , wherein recesses are optionally also possible in the side surfaces as shown in  FIG. 23 . 
     The closure  10  shown in  FIGS. 31 and 32  can only be introduced from above into the deposit device  23  so that insertion from the side, as shown in  FIG. 27 , is not possible. The other two options shown in  FIGS. 28 and 30  can also be implemented with the closure  10  of  FIG. 31 . The closed container is inserted between the defining limbs  22  which project up from the cover plate  21 , into the deposit device  23  adjoining the container mounting  40 , the projections  24  passing into the recesses  16  ( FIG. 32 ). The container is now further pushed into the container mounting  40 , with the closure  10  remaining in the deposit device  23 . If the container  1  is to be replaced when empty or when still partially filled it is moved back again into the deposit device  23 , in which case the closure  10  which is locked in that direction by the defining limb  22  is again pushed on to the connection  2  and sealingly closes the container. Subsequently the closed container is removed. 
     In this embodiment a number of coding options are also afforded by a variation in the projections  24 , in the region of the deposit device  23  for the closure  10 . The projections  24  project from the edge of the container mounting  40  and engage into the recess  16  at the side surface  18  of the closure  10 . The closure  10  again remains in the deposit device  23  when the container  1  is pushed into the container mounting  40 . 
       FIGS. 33 through 36  show coding elements at the top side  19  of the closure  10 , in which respect as shown in  FIG. 33  the recesses  16  are in the form of cylindrical depressions, possibly also holes, while in  FIG. 35  they are in the form of cylindrical projections  26 . The corresponding counterpart portions are provided in the bottom surface of the deposit device  23 , that is to say as shown in  FIG. 34  the projections  28  shown in broken lines project there in the form of cylindrical knobs or the like and in  FIG. 36  depressions  25  are in the form for example of cylindrical blind holes in the cover  21 . 
     Projections  24 ,  27 ,  28  (limbs, noses, knobs and so forth) projecting into the deposit device  23  allow holes in the cover plate  21 , which are covered over by the projections  24 ,  27 ,  28 , to provide tamper protection. If those projections of the deposit device  23  are removed in order to be able to insert for example containers  1  as shown in  FIG. 1  without a recess  16  in the closure  10  then those holes are exposed. 
     Preferably provided in the dispenser  20  beneath the cover  21  is a chamber (in particular an intermediate container, a pump chamber or the like), into which the liquid flows out of the container  1  fitted into the container mounting  40  ( FIG. 19 ) and which loses sealing integrity due to the removal of the projection  24 . 
     In  FIGS. 29 and 32  the closure  10  is sectioned in each case parallel to the plane of the container opening  3  whereby engagement of the projections  24  into the recess  16  is more clearly apparent. The section plane extends directly beneath the limbs  11  of the closure  10 . 
     The section planes in  FIGS. 34 and 36  are in the same position, with the closure  10  not being shown in  FIG. 36 . 
     In  FIGS. 28 and 30  the projections  24  projecting into the deposit device  23  are subdivided horizontally whereby a second projection  27  remains at the bottom of the deposit device  23 , and that projection, as mentioned above, exposes a hole in the cover when it is removed.
