Claim 1
Independent Claim
166 words
A wicket bag packet comprising, in combination: (a) a stack of flattened, flexible packaging bags, each of said bags having an open end and having a pair of wicket holes provided in a portion thereof adjacent to said open end; and (b) a wicket including a substantially U-shaped rigid uper member having a pair of elongated leg sections adapted to pass through said pair of wicket holes provided in each bag and a substantially U-shaped flexible lower member having a pair of elongated leg sections extending through said pair of wicket holes provided in each bag and holding together the entire stack of packaging bags, said rigid upper member extending outwardly beyond said stack of packaging bags and having its elongated leg sections joined contiguously with the elongated leg sections of said flexible lower member forming a continuous loop whereby a selected number of bags may be taken from said stack of packaging bags and guided along said rigid upper member to a separate packaging location.
Claim 2
Dependent Claim
166 words
A wicket bag packet comprising, in combination: (a) a stack of flattened, flexible packaging bags, each of said bags having an open end and having a pair of wicket holes provided in a portion thereof adjacent to said open end; and (b) a wicket including a substantially U-shaped rigid uper member having a pair of elongated leg sections adapted to pass through said pair of wicket holes provided in each bag and a substantially U-shaped flexible lower member having a pair of elongated leg sections extending through said pair of wicket holes provided in each bag and holding together the entire stack of packaging bags, said rigid upper member extending outwardly beyond said stack of packaging bags and having its elongated leg sections joined contiguously with the elongated leg sections of said flexible lower member forming a continuous loop whereby a selected number of bags may be taken from said stack of packaging bags and guided along said rigid upper member to a separate packaging location.
Claim 3
Dependent Claim
239 words
A wicket bag packet comprising, in combination: (a) a stack of flattened, flexible packaging bags, each of said bags having an upper and a lower ply joined together along the edges thereof except at one edge forming a bag opening, said upper ply being shorter than said lower ply so as to clear said lower ply and provide a lip portion adjacent to said bag opening, said lip portion having a pair of wicket holes provided therein; and (b) a wicket including a substantially U-shaped rigid upper member having a straight horizontal center section adapted to bear down on the lip portion of each bag for holding said bag in place at a separate packaging station and having a pair of elongated leg sections adapted to pass through said pair of wicket holes provided in said lip portion of each bag and a substantially U-shaped, flexible lower binding member having a pair of elongated leg sections extending through said pair of wicket holes provided in each bag and holding together the entire stack of packaging bags, said rigid upper member extending outwardly beyond said stack of packaging bags and having its pair of elongated sections joined contiguously with the pair of leg sections on said flexible lower binding member forming a continuous loop whereby a selected number of bags may be taken from said stack of packaging bags and guided along said rigid upper member to said packaging station.
