Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
159 words
A drinking bag comprising a tubular portion having flexible sidewall means, means at the upper end of said tubular portion joining sidewall means to form at least one sloping shoulder, said shoulder being substantially rigid with respect to said flexible sidewall means and substantially nonexpansible sidewise in the direction of the shoulder, said means providing the shoulder converging to a fixed outlet having an openable closure assembly, and means providing a closed lower bag portion comprising a deformable bottom support structure peripherally sealed to said tubular portion, said bottom structure being substantially nonexpansible in said sidewise direction but being deformable under the weight of liquid in the bag to permit expansion of the wall means at the bottom of said tubular portion sidewise relative to said shoulder when the bag contains a liquid, and said bottom support structure when expanded by the weight of the liquid contents of said bag being capable of supporting the bag in upright position.
Claim 2
Dependent Claim
159 words
A drinking bag comprising a tubular portion having flexible sidewall means, means at the upper end of said tubular portion joining sidewall means to form at least one sloping shoulder, said shoulder being substantially rigid with respect to said flexible sidewall means and substantially nonexpansible sidewise in the direction of the shoulder, said means providing the shoulder converging to a fixed outlet having an openable closure assembly, and means providing a closed lower bag portion comprising a deformable bottom support structure peripherally sealed to said tubular portion, said bottom structure being substantially nonexpansible in said sidewise direction but being deformable under the weight of liquid in the bag to permit expansion of the wall means at the bottom of said tubular portion sidewise relative to said shoulder when the bag contains a liquid, and said bottom support structure when expanded by the weight of the liquid contents of said bag being capable of supporting the bag in upright position.
