Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 191 words
In a sealable closure arrangement for a plastic container body and a fully removable cover of like material therefor: (a) a unitary, tubular body having an open upper end terminating in an annular stiffening rib; (b) said rib having a shoulder extending radially from said body; (c) a cover having a central portion and a peripheral rim arranged to lie upon said annular stiffening rib in sealing engagement therewith; (d) clamping structure for maintaining said rib and said peripheral rim in sealing engagement comprising a clamping band engageable with said stiffening rib and said peripheral rim, the upper extremities of said clamping band being in engagement with said peripheral rim and the lower extremities of said clamping band being in engagement with said annular stiffening rib; (e) the lower extremities of said clamping structures being in the form of a skirt discontinuous at intervals throughout the length thereof to provide for constriction thereof about said container body at said stiffening rib; (f) said skirt having a guideway therein for a strand positioned therein and adapted to be tensioned so as to force said skirt against said shoulder and said container body.
Claim 2
Dependent Claim 191 words
In a sealable closure arrangement for a plastic container body and a fully removable cover of like material therefor: (a) a unitary, tubular body having an open upper end terminating in an annular stiffening rib; (b) said rib having a shoulder extending radially from said body; (c) a cover having a central portion and a peripheral rim arranged to lie upon said annular stiffening rib in sealing engagement therewith; (d) clamping structure for maintaining said rib and said peripheral rim in sealing engagement comprising a clamping band engageable with said stiffening rib and said peripheral rim, the upper extremities of said clamping band being in engagement with said peripheral rim and the lower extremities of said clamping band being in engagement with said annular stiffening rib; (e) the lower extremities of said clamping structures being in the form of a skirt discontinuous at intervals throughout the length thereof to provide for constriction thereof about said container body at said stiffening rib; (f) said skirt having a guideway therein for a strand positioned therein and adapted to be tensioned so as to force said skirt against said shoulder and said container body.
