Abstract
Abstract A bag member has a tubular body with a sealable inner surface having a peripheral strip of nonresiliently deformable material secured thereover. The strip is spaced downwardly from the upper end of the body to partially block the sealable material and to expose a peripheral band thereof above the strip at which sealing can be effected. Because the deformable material is nonadherent to itself, subjecting the upper end portion of the body to sealing conditions effects a seal at a location which is substantially limited to the exposed band of sealable material; because the deformable material is nonresilient and capable of maintaining a folded configuration, opposing portions of it may be interengaged by folding the bag along the strip to provide a closure for the bag.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
197 words
A bag member comprising a generally tubular body of synthetic plastic sheet material having a recloseable end portion with a heat sealable inner surface, and a relatively thin, substantially continuous strip of nonresiliently deformable material extending about substantially the entire inner periphery of said end portion and secured to said end portion at a point spaced from the edge thereof, said strip partially blocking said sealable surface to substantially prevent sealing thereat and the edge portion between said edge and strip providing a peripheral band of sealable surface at which sealing of the inner surface may be effected, said strip being dimensioned relative to the length of said body so as to be located adjacent said end portion with the major portion of said body being free from said strip, said deformable material being capable of maintaining a folded configuration and being nonadherent to itself under the conditions of sealing for said sealable surface so that subjecting said end portion to the sealing conditions effects a seal in a location substantially limited to said peripheral band, and said bag member is recloseable by folding said bag member along said strip to interengage opposed portions of said strip.
Claim 2
Dependent Claim
197 words
A bag member comprising a generally tubular body of synthetic plastic sheet material having a recloseable end portion with a heat sealable inner surface, and a relatively thin, substantially continuous strip of nonresiliently deformable material extending about substantially the entire inner periphery of said end portion and secured to said end portion at a point spaced from the edge thereof, said strip partially blocking said sealable surface to substantially prevent sealing thereat and the edge portion between said edge and strip providing a peripheral band of sealable surface at which sealing of the inner surface may be effected, said strip being dimensioned relative to the length of said body so as to be located adjacent said end portion with the major portion of said body being free from said strip, said deformable material being capable of maintaining a folded configuration and being nonadherent to itself under the conditions of sealing for said sealable surface so that subjecting said end portion to the sealing conditions effects a seal in a location substantially limited to said peripheral band, and said bag member is recloseable by folding said bag member along said strip to interengage opposed portions of said strip.
Claim 3
Dependent Claim
17 words
The bag member of claim 1 wherein said sealable surface is provided by a synthetic thermoplastic polymer.
Claim 4
Dependent Claim
68 words
The bag member of claim 1 wherein said body is formed of a length of heat-sealable synthetic thermoplastic polymeric sheet material having substantially parallel longitudinal edges, and wherein said strip is provided by an elongated deformable element secured transversely of said length of sheet material and substantially perpendicular to said longitudinal edges thereof, said body having a longitudinally extending heat-sealed portion securing said longitudinal edges in overlapping relationship
Claim 5
Dependent Claim
50 words
The bag member of claim 3 wherein one end of said deformable element is secured adjacent and short of the longitudinal edge of the overlying ply of said sheet material so that said longitudinally extending heat-sealed portion extends transversely over a portion of said element adjacent the other end thereof.
Claim 6
Dependent Claim
72 words
The bag member of claim 4 wherein said element has an aperture therein adjacent said one end and wherein said other end thereof projects beyond the longitudinal edge of the underlying ply of said sheet material and projects beneath said one end and said aperture, said sheet material being bonded to said element adjacent said other end thereof through said aperture to prevent substantially relative movement of the ends of said element.
Claim 7
Dependent Claim
75 words
The bag member of claim 1 wherein said metal foil element is adhesively secured to said sealable surface by a heat seal along a line extending longitudinally of said element and spaced from the edge thereof adjacent the band, so that an unsecured edge portion of said strip extends beyond said heat seal to reduce any tendency for the edge thereof to sever said body at a weakened zone produced directly adjacent said heat seal.
Claim 8
Dependent Claim
34 words
The bag member of claim 6 wherein said edge of said element is relatively sharp and provides a cutting edge to facilitate tearing and removal of the end portion of said body extending therebeyond.
Claim 9
Dependent Claim
30 words
The bag member of claim 3 wherein the lower end of said tubular body is sealed by a heat seal extending transversely and generally perpendicular to the longitudinal edges thereof.
Claim 10
Dependent Claim
26 words
The bag Member of claim 8 additionally including an article therewithin, said bag member being sealed within said peripheral band to provide a recloseable sealed container.
