Definitions
- the present invention relates to a display device for bundled bags, in particular plastic bags, and such a bag.
- these display devices include means making it possible to keep the bags assembled in a bundle hanging so that the extreme bag can be loaded while being kept open and suspended.
- the bags all have a strain, threaded onto a retaining bar and linked to said bag by a breakable part.
- a retaining bar is sometimes provided at the end with a locking means, capable of preventing the removal of the bundle of bags.
- the bags used on this type of display mostly consist of plastic bags, having two straps in each of which is made one of the two holes for threading the hanging rods, while the strain consists of two tabs extending from the upper edge of each of the front and rear walls, between the two shoulder straps, said tabs being pierced with a hole and connected precariously to said walls by means of the breakable parts resulting from a partial cutting by example.
- the functioning of the system is based on a certain balance, namely that on the one hand the bonding by glue points or the like must be more resistant than that by breakable parts to allow the following bag to be driven; and on the other hand said glue point or similar connection must be less resistant than the addition of the resistance of the breakable parts to that of the friction of the bag on the suspension rods in order to allow the breaking of said glue point or similar connection and opening the next bag.
