Abstract
Abstract The present invention relates generally to improvements in manually transportable carriers for accommodating a plurality of containers, as for example, bottles and the like, and more particularly, to container carriers of the reuseable type comprised of a single folded sheet of material. The end walls of the carrier comprise integral brace members connected between the bottom wall and the side walls of the carrier. These brace members are further slidably interlocked in slots in the center wall of the carrier.

Claim 1
Independent Claim
338 words
A container carrier formed from a folded sheet of material and foldable alternatively into a substantially flat storage condition and an open container receiving condition, said carrier comprising a pair of side walls joined at the upper side edges thereof, a plurality of container receiving apertures formed in each side wall and arranged in a row between the ends of said side walls, a bottom wall divided into two separate sections and foldable along the line of division with each of said sections further foldably joined to the lower edge of one of said side walls, a center wall foldably joined to both of the bottom wall sections along said line of division, said center wall extending beTween said side walls and through the upper side edges thereof to terminate in a handle, whereby said separate sections of said bottom wall and said side walls are folded against the opposite sides of said center wall in said flat storage condition of said carrier, an end brace assembly for each end of said carrier, each end brace assembly comprising a pair of brace members, each of said brace members joined at one end thereof to the end marginal edge of one of said side walls, each of said brace members joined at the other end thereof to the end marginal edge of one of said bottom wall sections, said brace members having lengths permitting substantially flat engagement of said brace members on opposite sides of said center wall in said flat storage condition of said carrier, said center wall have elongated apertures at each end thereof, means joining each pair of said pairs of brace members together intermediate the ends thereof and within one of said apertures, and the longitudinal axes of said elongated apertures aligned vertically of said center wall to permit said means joining each pair of said pairs of brace members together to vertically move within said apertures contemporaneously with any folding of said carrier between said flat storage condition and said open container receiving condition.

A container carrier formed from a folded sheet of material and foldable alternatively into a substantially flat storage condition and an open container receiving condition, said carrier comprising a pair of side walls joined at the upper side edges thereof, a plurality of container receiving apertures formed in each side wall and arranged in a row between the ends of said side walls, a bottom wall divided into two separate sections and foldable along the line of division with each of said sections further foldably joined to the lower edge of one of said side walls, a center wall foldably joined to both of the bottom wall sections along said line of division, said center wall extending beTween said side walls and through the upper side edges thereof to terminate in a handle, whereby said separate sections of said bottom wall and said side walls are folded against the opposite sides of said center wall in said flat storage condition of said carrier, an end brace assembly for each end of said carrier, each end brace assembly comprising a pair of brace members, each of said brace members joined at one end thereof to the end marginal edge of one of said side walls, each of said brace members joined at the other end thereof to the end marginal edge of one of said bottom wall sections, said brace members having lengths permitting substantially flat engagement of said brace members on opposite sides of said center wall in said flat storage condition of said carrier, said center wall have elongated apertures at each end thereof, means joining each pair of said pairs of brace members together intermediate the ends thereof and within one of said apertures, and the longitudinal axes of said elongated apertures aligned vertically of said center wall to permit said means joining each pair of said pairs of brace members together to vertically move within said apertures contemporaneously with any folding of said carrier between said flat storage condition and said open container receiving condition.
Claim 3
Dependent Claim
41 words
A container carrier as defined in claim 1, wherein the material of said carrier is a heat sealable plastic material and wherein said means joining said brace members together comprises a heat sealing of said brace members to form the junctions.
Claim 4
Dependent Claim
45 words
A container carrier as defined in claim 2 wherein said junctions of said brace members are exposed in directions perpendicular to the plane of said carrier when the side walls and bottom wall section are folded against said center wall in said flat storage condition.
