DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a coupling device for connecting a material outlet to a packing, preferably designed for viscous material and having walls of plastic foil, whereby the coupling device comprises two interconnectable coupling means one of which is mounted on the packing and the other on the material outlet.
It is previously known to provide packings of various types with an opening and an outer connection piece at which a hose is connectable such that material may be fed out of the packing via the opening and the hose. Such an arrangement is suitable if the hose is applicable at the connection piece before the packing is filled with material or if a filled packing is easy to handle or form such that the hose may be applied afterwards without material flowing out, e.g. by temporarily turning the packing upside down so that the connection piece is directed upwards, which means that material can not flow out while the connection piece is opened and the hose is connected.
However, there are packings, e.g. of plastic foil, which are difficult to handle in such a way that a hose or another material outlet is quickly and efficiently applicable without risk for overflow.
The object of the present invention is to eliminate said problem and provide a device by simple means which permits application of a material outlet at the packing in a simple and efficient way without remedies and competence. According to the invention this is achieved at while the coupling means of the packing is mounted on an unbroken wall portion of the packing and provided with a separating portion arranged inside the packing and having a grip portion for the coupling means of the material outlet, side openings for through-flow of material and a support portion directed towards an opposed wall portion of the packing, whereby the coupling means of the material outlet has a hole-punching portion for punching the unbroken wall portion and a grip portion for securable fitting in the grip portion of the separating portion after punching.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be further described hereinafter with reference to the accompanying drawings in which
FIG. 1 with a side view illustrates a half-filled packing to which a hose is connected via a coupling device according to the invention;
FIG. 2 is a section through an enlarged part of an almost empty packing to which a hose is connected via a coupling device according to the invention;
FIG. 3 is a section through a part of a filled packing before applying a hose via a coupling device according to the invention and
FIG. 4 illustrates the part of the packing shown in FIG. 3 when connecting the hose via the coupling device according to FIG. 3.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
In FIG. 1 a container 1 is shown having a suspension device 2 on which a packing 3 is suspended. The packing 3 has two opposed walls 3a and 3b of foil material and contains a viscous mass 4, e.g. tomato ketchup, mustard or sauce. For feeding the viscous mass 4, the packing 3 is interconnectable to a feeding device 5 e.g. including a pump 5a, a conduit 5b for connection to the packing 3, a check valve 5c for preventing return flow of the mass 4 to the packing 3 and a conduit 5d extending from the pump 5a for portioning the viscous mass 4 out of the system. The pump 5a of the feeding device 5 is designed to suck out the viscous mass 4 from the packing 3 until it reaches the pump and to press out the mass 4 in the pump 5a via the portioning conduit 5d. Since such a principal of feeding is well known as well as devices for carrying out said principal, it has been only briefly described and the device shown schematically. In order to be able to connect said feeding device 5 or a material outlet of another type to the packing 3, a coupling device 6 is used having a coupling means 6a mounted on the packing 3 and a coupling means 6b mounted on the material outlet 5.
Especially regarding storage of food in the packing 3, it is essential that the packing can be transported and deli
