Abstract
Abstract A container of composite construction which comprises a widemouthed inner shell formed of seamless thermoplastic material in a generally frusto-conical configuration so that like shells are nestable in a compact stack, the sidewall portion of the shell being of relatively thin and fragile construction, and which further comprises an externally decorated, relatively stiff paperboard sleeve which is wound around the side wall portion of the shell and which is adhesively secured in face to face reinforcing contact therewith, the opposed ends of the blank from which the sleeve is formed each comprising a series of alternating recesses and protrusions which are interengageable with corresponding protrusions and recesses in the other end to accurately register the ends of the sleeve with respect to one another in a serpentine-shaped butt seam. In the preferred embodiment, the side wall of the inner shell is provided with a stacking shoulder immediately below the rim portion of the shell to facilitate denesting of nested shells and/or denesting of nested finished containers and, when the outer sleeve is joined to the inner shell by a water based or solvent-based adhesive, the stacking shoulder may advantageously be provided with a circumferentially spaced series of vent indentations to permit the escape of adhesive vapors from a stack of nested finished containers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
236 words
A composite container comprising, in combination: an inner shell formed of a thermoplastic material and including a rim portion defining the open end of said container, a base portion, and a surrounding side wall portion extending upwardly from said base portion to said rim portion; and a sleeve formed from a double-ended blank of paperboard stock which is decorated on one surface thereof, said sleeve being wound around the side wall portion of the inner shell with the other surface of the sleeve covering a major portion of said side wall portion and being secured thereto in reinforcing relationship, the circumferential extent of all portions of said sleeve being no greater than the circumferential extent of the portion of the side wall of the inner shell which is immediately adjacent thereto so that no portion of one end of the blank from which the sleeve is formed overlaps any portion of the other end thereof in the finished container, the opposed ends of the sleeve each comprising a series of alternating protrusions and recesses with the protrusions and recesses on each end being so arranged as to be interengageable with corresponding recesses and protrusions of the other end to form a serpentine shaped butt seam between the ends of the sleeve and to thereby insure accurate registration of the decorated portions of the outer surface of the sleeve which are proximate to said opposed ends thereof.
Claim 2
Dependent Claim
236 words
A composite container comprising, in combination: an inner shell formed of a thermoplastic material and including a rim portion defining the open end of said container, a base portion, and a surrounding side wall portion extending upwardly from said base portion to said rim portion; and a sleeve formed from a double-ended blank of paperboard stock which is decorated on one surface thereof, said sleeve being wound around the side wall portion of the inner shell with the other surface of the sleeve covering a major portion of said side wall portion and being secured thereto in reinforcing relationship, the circumferential extent of all portions of said sleeve being no greater than the circumferential extent of the portion of the side wall of the inner shell which is immediately adjacent thereto so that no portion of one end of the blank from which the sleeve is formed overlaps any portion of the other end thereof in the finished container, the opposed ends of the sleeve each comprising a series of alternating protrusions and recesses with the protrusions and recesses on each end being so arranged as to be interengageable with corresponding recesses and protrusions of the other end to form a serpentine shaped butt seam between the ends of the sleeve and to thereby insure accurate registration of the decorated portions of the outer surface of the sleeve which are proximate to said opposed ends thereof.
Claim 3
Dependent Claim
41 words
A composite container according to claim 1 wherein the side wall portion of the inner shell extends upwardly and outwardly from the base portion of the shell to the rim portion thereof whereby said shell is nestable with similarly shaped shells.
Claim 4
Dependent Claim
59 words
A composite container according to claim 2 wherein said side wall portion of said shell comprises a stacking shoulder immediately below the rim portion of the shell, said stacking shoulder being engageable with the rim of another similarly shaped shell into which said shell may be inserted in nested relationship to permit rapid denesting of said shell when desired.
Claim 5
Dependent Claim
35 words
A composite container according to claim 3 wherein a major portion of said other surface of the sleeve is adhesively joined to the side wall portion of the shell in face to face contact therewith.
Claim 6
Dependent Claim
45 words
A composite container according to claim 4 wherein said stacking shoulder comprises a plurality of circumferentially spaced vent indentations therein to permit the escape of adhesive vapors from a stack of nested and similarly shaped composite containers with which said composite container may be nested.
Claim 7
Dependent Claim
46 words
A composite container according to claim 1 wherein said sleeve is secured to said shell by means of an adhesive which adhesively joins at least a major portion of the inner surface of the sleeve to the adjoining portion of the side wall of the shell.
Claim 8
Dependent Claim
30 words
A composite container according to claim 6 wherein substantially the entire inner surface of the sleeve is adhesively joined to the adjoining portion of the side wall of the shell.
