Abstract
Abstract The invention refers to wicket bags in which each bag is made from any suitable flexible material, such as polyethylene, polypropylene or other equivalent materials, and has two vertical closed sides and a bottom closed side and leaving an open mouth forming the fourth side. The rear and front walls of the bags are of equal lengths and have their vertical edges heat-sealed for the greater extent of their lengths, thus forming closed vertical sides, and leaving the vertical edges of the upper portions of the rear and front walls freely independent from one another so as to form the open mouth of the bag. The upper portion of the front wall thus becomes a free transverse portion, which is capable of being folded in a downward direction on the exterior surface of its front wall to form a lip, and leaving the upper portion of the rear wall exposed and which is provided with apertures located adjacent to its top edge for engagement by the legs or posts of a wicket. When the bag is filled with the required items, it is removed from the wicket, and the position of the folded lip is then changed and extended in an opposite direction so as to cause the front wall to be of equal length to the length of the rear wall. The open mouth of the bag is then suitably closed and tied.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
A wicket bag made from a synthetic resin or other materials, comprising a rear wall and a front wall of equal lengths, having independent top edges and vertical edges heat-sealed to one another for the greater portions of their lengths and said heatsealed vertical edges terminating at a predetermined distance from the top edges of the rear and front walls, upper portions forming a part of said rear wall and said front wall and bounded by free vertical edges which extend from the termination of the heat-sealed vertical edges and the top edges of said rear and front walls and forming the open mouth of the bag, the upper portion of said front wall having a transverse crease line extending across the width of said bag and terminating at the junctures of the free vertical edges with the heat-sealed vertical edges to form a transverse lip, said lip being folded from the aforesaid transverse crease line and heat-sealed to said front wall and forming a recess which is adapted to be engaged by means for opening and expanding the mouth of the bag.
Claim 2
Dependent Claim
183 words
A wicket bag made from a synthetic resin or other materials, comprising a rear wall and a front wall of equal lengths, having independent top edges and vertical edges heat-sealed to one another for the greater portions of their lengths and said heatsealed vertical edges terminating at a predetermined distance from the top edges of the rear and front walls, upper portions forming a part of said rear wall and said front wall and bounded by free vertical edges which extend from the termination of the heat-sealed vertical edges and the top edges of said rear and front walls and forming the open mouth of the bag, the upper portion of said front wall having a transverse crease line extending across the width of said bag and terminating at the junctures of the free vertical edges with the heat-sealed vertical edges to form a transverse lip, said lip being folded from the aforesaid transverse crease line and heat-sealed to said front wall and forming a recess which is adapted to be engaged by means for opening and expanding the mouth of the bag.
Claim 3
Dependent Claim
245 words
A wicket bag made from a synthetic resin or other suitable materials, comprising a rear wall and a front wall of equal lengths, having independent top edges and vertical edges heat-sealed to one another for the greater portions of their lengths and said heat-sealed vertical edges terminating at a predetermined distance from the top edges of the rear and front walls, upper portions forming a part of said rear wall and said front wall and bounded by free vertical edges which extend from the termination of the heat-sealed vertical edges and the top edges of said rear and front walls and forming the open mouth of the bag, the upper portion of said front wall having a transverse crease line extending across the width of said bag and terminating at the juncture of the free vertical edges with the heat-sealed vertical edges to form a transverse lip, said lip being folded from the aforesaid transverse crease line and partibly heat-sealed to said front wall and forming a recess which is adapted to be engaged by means for opening and expanding the mouth of the bag, whereby in operation, when the bag has been removed from its wicket, it may be converted from a wicket bag into a regular bag through severing the partibly heat-sealed connections between said folded lip and said front wall and unfolding the folded lip and extending the same, so that both the rear and front walls are of the same lengths.
