Abstract:
In dispensers for liquid products bags, with a hose-like emptying opening at the lower end of the bag are used, with emptying achieved by compression of the hose. Emptying is improved if two flat surfaces approach each other and additional improvement is obtained if the surfaces are provided with means to achieve throttling prior to compression.

Description:
BACKGROUND OF THE INVENTION 
     This application is a filing under 35 USC 371 of PCT/SE02/02051 filed Nov. 12, 2002. 
     The present invention relates to a holder for a container for liquid products. A device for a holder for a container for liquid products for application on a wall is known, which container may be made of various materials such as plastic, glass, paper, metal or the like and which may be in the nature of a bag or bottle with a preferably detachable closure means that is elongate, which includes a dosing member such as a pump arrangement that can be influenced externally transversely and manually by part of an actuating member such as a lever pivotably journalled in the holder, the container with an elongate closure means being designed to rest against the container, the blank for the container consisting of a substantially rectangular plate with a longitudinal and a transverse extension, which plate in its longitudinal direction has a longitudinally-running through-slot with two parts arranged one on each side of the slot and which plate is shaped substantially as a U about an axis perpendicular to the slot, the plate part on one side of the slot being bent inwards so that the plate part forms a U-like part that is intended with its outer part to surround and limit lateral movement of the elongate closure means and the plate part on the other side of the slot retaining its outwardly directed shape and with its inner part being intended to partially surround the container and its elongate closure means. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide a device such that upon movement of the actuating member a predetermined amount of the liquid product is supplied. In accordance with the present invention this is achieved by said hose-like part being squeezed together along a predetermined length thereof so that said part is totally emptied of its contents. This is achieved by the actuating member cooperating with the outer surface of the inwardly bent part of the rectangular plate. Said outer surface cooperates with a part of the actuating member which is substantially parallel with said surface in inserted position. It is thus suitable for the actuating member in inserted position to have a part that is parallel with said outer surface. The quantity of product squeezed out will thus be determined by the length of the part of the actuating member that cooperates with said outer surface of the inwardly bent part. It is thus suitable for the inwardly bent part to have an entirely flat rectangular surface at its centre. The actuating member may also be provided with a plate cooperating with the surface just mentioned. 
     The actuating member and/or the inwardly bent outer surface may be provided on the side closest to the container with means to throttle the hose before the squeezing effect occurs. The liquid product from the hose is thus prevented from returning to the container. The hose may be provided at its free end with a valve that is resilient and always assumes closed position but which, upon being influenced by pressure from the liquid product in the hose, opens and permits a certain quantity to be released.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Let us consider  FIGS. 1 and 2  showing a known holder and material required for its manufacture. A rectangular plate is used initially, which is provided with a central opening  6  and two plate-shaped parts  7  and  8 , one on each side of the slot. Holes  9  and  10  are also provided for attaching the bent plate. The plate illustrated in  FIG. 2  is bent in the manner shown in  FIG. 1  where the plate  5  is U-shaped. It is the part of the plate to the right of the slot  6  that forms the upper part  8  of the holder and the part to the left of the slot  6  that forms the inwardly bent wall  7  that is to constitute the contact wall against a tapping part of a container with liquid products. The bent unit has two attachment flanges  13  and  14  with holes  15  and  16  for attachment screws. From the bent unit  5  extend two rods  1  and  2  with a curved part  3  and the intention is for a bag or bottle to be inserted between the curved part and the straight parts, down to the inwardly bent wall  7 . The parts of the receptacle near the inwardly bent part of the holder are influenced by the actuator  17  with two side arms  19  and  20  provided at their free ends with pins  21  and  22  journalled in holes  11  and  12  in the bent metal plate  5 . 
     Another known device has been developed which deviates somewhat from the holder shown in  FIG. 1  in that the holder part  8  has been made considerably shorter and the actuator is arranged differently, having a longer, flat, straight part  18  that shall be brought more or less into contact with a tubular part  25  which also requires a support  24  for its free end. The most important feature of the holders illustrated in  FIGS. 3 and 4  is that they are suitable for receptacles containing liquid products and having a long pipe such as the discharge pipe  25  which may include a pump or other means of discharging liquid. 
       FIG. 5  illustrates a device similar to that shown in  FIG. 4  but with a tubular casing, optional in shape, into which casing a box with contents as in  FIG. 4  can be inserted. The casing may have a smooth surface or it may consist of a number of parallel slats arranged one after the other, or of a mesh frame. In certain cases it is desirable to surround a receptacle containing liquid products with a protective casing so that it cannot be interfered with. In this case a double casing is used consisting of a flat part  31  with two side flanges  35  and  36  cooperating with a domed casing  30 . This is provided at its lower end with journalling pins  26  running in closed slots  34 , i.e. the journalling pins  26  are displaceable from one end of the slot to its other end. If the domed part  30  is flapped down towards the part  31  the studs  27  will engage in the grooves  32  and  33  which have openings. Thus, if the domed part  30  is flapped down towards the part  31  the studs  27  will cooperate with the grooves  32  and  33  and in closed position the domed part  30  can be moved to the lower end of the slot  34  and in this position the domed part  30  can be locked to the flat part  31  so that the receptacle with liquid products is inaccessible for damage. As can be seen in  FIG. 7 , to open the domed outer casing it must be moved upwards some distance until it can be folded out and assume a position perpendicular to the part  31 . The reason for this upward movement is, when the domed casing is down, to protect the actual holder arrangement. It should be evident that the casing described in  FIGS. 6 ,  7  and  9  can very well be used for holders other than the one depicted in the description. 
     The known arrangements described above have the drawback that it is impossible to discharge a specific quantity of liquid product. 
     An embodiment of the present invention will now be described in more detail with reference to  FIG. 10 . This embodiment differs from, that described above in that the inwardly bent part  7  is provided at its mid-section with a flat surface  40  and in that the part  18  of the lever  17 , see  FIGS. 10 and 11 , is provided with a plate  37  intended to cooperate with the flat surface  40  in such a way that when the lever is in its lowermost position the plate  37  and surface  40  will be substantially parallel and, upon further depression, the hose  25  within will be entirely compressed along a length corresponding to the length of the plate  37 . The plate  37  has an outwardly bent part  38 , as is also the case at the upper end of the flat surface of the inwardly bent part where a flange  39  or the like is arranged, whereupon the parts  38  and  39  throttle the hose  25  before the hose is compressed by the parts  37  and  40 . The flat plate  5  (see  FIG. 2 ) is also provided with a second groove  41  and, thanks to this, a protruding part  42  is obtained that can serve as support for the hose. It may be suitable to arrange a resilient valve at the end of the hose, this valve being designed to open and release the predetermined quantity of liquid product when liquid product from the hose subjects the valve to pressure. 
       FIG. 11  shows a second embodiment of the present invention differing from the previous embodiment in that the plate  37  has been replaced by a specially shaped part  18  of the lower part of the lever  17 . The lower part  18  will function in exactly the same way as the part  38  of the plate  37 . Furthermore, the inwardly bent part  7  has an inwardly curved flange  44  at its upper end, corresponding to the unit  39  in  FIG. 10 . A transverse part  43  attached on the specially shaped part  18  of the lever  17  cooperates with the above-mentioned unit. 
     In the above throttling was achieved with the aid of two parts that were movable in relation to each other. Naturally throttling may be achieved in any manner whatsoever. The valve arrangement at the end of the hose may also be designed in various ways that offer the same function as that described.
