Date Jul. 23, 1981.A coupling device for connecting a material discharge to a packing, preferably with walls of plastic foil for viscous material, comprises two interconnectable coupling members, one of which is mounted on the packing and the other on the material discharge. The coupling device permits application of a material discharge to the packing in a quick and efficient manner. A packing coupling is mounted on an unbroken wall portion of the packing and is provided with a separating portion disposed inside the packing. The separating portion comprises a grip portion for the material discharge coupling, side openings for flow-through of material and a support portion directed towards an opposed wall portion of the packing. The material discharge coupling is provided with a hole-punching portion for punching the unbroken wall portion and a grip portion which is designed to securably fit into the grip portion of the packing coupling after punching. |
