DESCRIPTION:

BRIEF SUMMARY
The present invention relates to a bag dispensing device comprising a container with a supply of bags and a nozzle in one of the walls of the container. The bags can leave the container via this nozzle.
A dispensing device of this generic type is already known in the art. The nozzle of this appliance has flexible and opposing elements, which are pressed against each other. The bags must pass between these elements as they leave the container. The nozzle is essentially round and, as the bags go through this nozzle, they are compressed into the form of a rope, which facilitates the separation of the respective bag from the supply of bags. It has turned out, amongst other things, to be extremely tedious to introduce bags from a new supply pack into a nozzle of this kind.
The object of the present invention is to eliminate this and other disadvantages of the state of the art.
According to the invention, the stated object is achieved with the device of the generic type mentioned in the introduction defined as a bag dispenser comprising a container (1) containing a supply (6) of bags (7) and nozzle (10) in one of the walls (3) of the container. The bags can leave the container via this nozzle (10). The nozzle (10) has a linear slit defined by braking lips (16, 17). At least one of the lips (16, 17) is fitted with braking elements (20) virtually parallel to each other and at right angles to the longitudinal axis of the slit.
Further details of designs for the present invention are given below, with accompanying drawings.
FIG. 1 is a view from the front, showing the present dispenser with a dispensing nozzle;
FIG. 2 shows a vertical section through the part of the device according to FIG. 1, which surrounds the nozzle;
FIG. 3 is a view from the front, showing the present device with its braking device for the dispensed bags;
FIG. 4 shows a vertical section of the part of the present device which surrounds the dispensing nozzle, wherein this device displays a second embodiment possibility for the braking device;
FIG. 5 is a view from the front, showing a second embodiment possibility for the lips of the braking unit on the nozzle, according to FIG. 1 and
FIG. 6 is a rear view of the lips according to FIG. 5.
The present dispensing device comprises a container (1), which has a front wall (3) and a basic frame (2), which can, for example, be fixed onto a wall. The front wall (3) is attached to the container frame by means of a hinge, which allows it to be tilted. There is a recess (5) in the front wall (3), to which a dispensing nozzle (10) is assigned. The bags can leave the container (1) via this nozzle (10). The nozzle (10) is assigned in such a way that the nozzle (10) overlaps the recess (5) on the outside.
Inside the container (1) there is a stock (6) of bags (7) (FIG. 3). The bags (7) in the supply (6) can be in the form of a roll or can be stacked in zig-zag fashion or other similar form. The bag (7) uppermost in the stock (6) is introduced through the opening in the nozzle (10) and, on the outer side of the front wall (3), it can be torn from the next bag (7) of the supply (6).
The cut-out free space section 56 defines the handles of the plastic bag which form the metaphorical shoulder straps of the "camisole-shaped" bag. The front ends of the handles 51 and 52 of the following "camisole-shaped" bag 71 are attached to the bottom edge 53 of the body of the leading camisole-shaped bag 7. Margin 55 of the hollow bag body 54 extends between the handles 51 and 52 of the bag 71 so that there exists a free space cut-out delineated by the handles 51 and 52, the bottom edge 53 of bag 7, and the margin 55 of the bag body 54. When the leading bag 7 is pulled out of the container nozzle 10, the bottom edge 53 of the leading bag 7 passes the lips of the nozzle 10 and pulls the front parts of the handles 51 and 52 out of the container. When the margin 55 reaches the lips of the nozzle 10, the bristles which overlap one another stop said top margin 55 of the following bag 71 at the location of the nozzle 10. Now, it is eas
