Abstract
Abstract A pouch has a pair of side walls which are connected at the longitudinal edges thereof, and bottom folds. A single handle is arranged at the bottom fold wherein one end of the handle is connected to one side wall and the other end is connected to the other side wall. The pouch and the handle consist of thermoplastic plastic foil and are connected to each other by a welding seam. At the filling opening, the pouch is provided with a suspension hole and a slot which extend from the outer rim in direction to the suspension hole in order to provide a bridge therebetween and to allow the pouch to be suspended from respective pins. Through tearing of the bridge between the suspension hole and the slot, a pouch can be removed from the stack of pouches.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
244 words
A pouch made of thermoplastic foil and comprising a pair of side walls each having longitudinal edges, bottom portion, and a top portion, the longitudinal edges of one of the side walls being connected to the associated longitudinal edges of the other of the side walls so as to define an interior, the bottom portions having bottom folds, the top portions after connecting the side walls to each other defining a filling opening opposite to the bottom fold of each side wall; and only one one-piece handle of one strip thermoplastic foil and having a width which is considerably smaller than a width of the side walls, said one-piece one strip handle being arranged in the region of the bottom folds and only in a central region spaced from the longitudinal edges and extending substantially parallel to the latter, said one-piece one strip handle having one end attached to the outside and only with the one of the side walls and another end attached to the outside and only with the other of the side walls so that a bridge between the one sidewall and the association bottom fold and between the other side wall and the associated bottom fold is prevented, the one and the other end of said one-piece one strip handle being welded to the associated side wall by a single welding seam which is of elongated oval shape and has an axis of elongation extending transversely of the longitudinal edges.

Claim 6
Dependent Claim
38 words
A pouch as defined in claim 1, wherein the handle has a length and each bottom fold of each side wall has a depth, the length of the handle corresponding to the depth of the both bottom folds.
Claim 7
Dependent Claim
252 words
A pouch made of thermoplastic foil and comprising a pair of side walls each having longitudinal edges, bottom portion, and top portion, the longitudinal edges of one of the side walls being connected to the associated longitudinal edges of the other of the side walls so as to define an interior, the bottom portions having bottom folds, the top portions after connecting the side walls to each other defining a filling opening opposite to the bottom fold of each side wall; and only one one-piece handle of one strip thermoplastic foil and having a width which is considerably smaller than a width of the side walls and which is equal over its whole length, said one-piece one strip handle being arranged in the region of the bottom folds and only in a central region spaced from the longitudinal edges and extending substantially parallel to the latter, said one-piece one strip handle having one end attached to the outside and only with the one of the side walls and another end attached to the outside and only with the other of the side walls so that a bridge between the one side wall and the association bottom fold and between the other side wall and the associated bottom fold is prevented, the one and the other end of said one-piece one strip handle being welded to the associated side wall by a single welding seam which is of elongated oval shape and has an axis of elongation extending transversely of the longitudinal edges.
