Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 280 words
Apparatus for successively dispensing paper-like bags each having opposite side walls and opposite end walls connected by a bottom wall and being foldable between an open condition and a collapsed condition with the end walls folded between the side walls and the bottom wall folded against one of the side walls, said apparatus comprising a box-like cabinet having a rectangular front opening and means for supporting a stack of substantially vertical collapsed bags with the upper end portion of said one side wall of the front bag in the stack exposed for manual gripping, means adjacent the sides of the front opening for restraining the other side wall of the front bag when said one side wall is pulled from said supporting means, at least one resilient rubber-like gripping member disposed adjacent the bottom of said front opening and having a gripping surface, said gripping surface extending above the lower folded edge of the front bag and engaging and gripping the bottom surface of the folded bottom wall of the front bag, a pressure member supported within said cabinet in back of the stack of bags for movement towards said front opening and cooperating with said gripping member to cause said gripping surface to press the folded bottom wall of the front bag against the adjacent side wall of the bag, and said gripping surface having a coefficient of friction sufficient to restrain and pull downwardly on the bottom wall of the front bag when said top end portion of said one side wall is pulled from the stack to cause unfolding of the bottom wall and automatic opening of the bag as the bag is remOved from the stack.
Claim 2
Dependent Claim 280 words
Apparatus for successively dispensing paper-like bags each having opposite side walls and opposite end walls connected by a bottom wall and being foldable between an open condition and a collapsed condition with the end walls folded between the side walls and the bottom wall folded against one of the side walls, said apparatus comprising a box-like cabinet having a rectangular front opening and means for supporting a stack of substantially vertical collapsed bags with the upper end portion of said one side wall of the front bag in the stack exposed for manual gripping, means adjacent the sides of the front opening for restraining the other side wall of the front bag when said one side wall is pulled from said supporting means, at least one resilient rubber-like gripping member disposed adjacent the bottom of said front opening and having a gripping surface, said gripping surface extending above the lower folded edge of the front bag and engaging and gripping the bottom surface of the folded bottom wall of the front bag, a pressure member supported within said cabinet in back of the stack of bags for movement towards said front opening and cooperating with said gripping member to cause said gripping surface to press the folded bottom wall of the front bag against the adjacent side wall of the bag, and said gripping surface having a coefficient of friction sufficient to restrain and pull downwardly on the bottom wall of the front bag when said top end portion of said one side wall is pulled from the stack to cause unfolding of the bottom wall and automatic opening of the bag as the bag is remOved from the stack.
Claim 3
Dependent Claim 79 words
Apparatus as defined in claim 1, wherein said means for supporting a stack of bags include a plurality of parallel spaced guide rods within the bottom portion of said cabinet and sloping downwardly to the bottom of said front opening, said guide rods being positioned to engage the lower folded edges of the bags within the stack, said gripping member is located adjacent the lower ends of said rods, and said pressure member is slidably mounted on said rods.
Claim 4
Dependent Claim 47 words
Apparatus as defined in claim 1, wherein said means for restraining the other side wall of each bag include a set of resilient restraining members mounted on said cabinet and positioned on opposite sides of said front opening to engage opposite end walls of each folded bag.
Claim 5
Dependent Claim 28 words
Apparatus as defined in claim 1, including a compression coil spring extending between said cabinet and said pressure member for urging said pressure member towards said front opening.
