Simplified collapsible container

Claim 2

In a simplified container construction including a bottom frame-fixed pallet portion and a bottom-demountable container portion mounted thereon, the bottom frame-fixed pallet portion comprising (1) a pallet composed of spaced parallel base boards, spaced parallel runners fixed on the base boards transversely thereof, longitudinal boards fixed on the runners longitudinally thereof, and spaced parallel transverse boards fixed on the longitudinal boards transversely thereof and just above the base boards respectively, and (2) a rectangular bottom frame having a L-shaped cross section and fixed on the pallet for receiving the bottom-demountable container portion, thus allowing the bottom frame-fixed pallet to have therein vertically free spaces through which the tines of a cargo-handling plunger may be put into, and out of, the bottom-demountable container portion.

Claim 3

The bottom frame-fixed pallet according to claim 1, wherein the runners have downwardly sloped ends and the longitudinal boards extend beYond the upper edges of the sloped ends of the runners thereby to form therebetween a recess through which ropes may be passed for loading or unloading the container.

Claim 4

A simplied container construction including a bottom frame-fixed pallet portion and a container portion mounted thereon, (A) the bottom frame-fixed pallet portion comprising (1) a pallet composed of spaced parallel base boards, spaced parallel runners fixed on the base boards transversely thereof, longitudinal boards fixed on the runners longitudinally thereof and spaced parallel transverse boards fixed on the longitudinal boards transversely thereof and just above the base boards respectively, and (2) a rectangular bottom frame having a L-shaped cross section and fixed on the pallet for receiving the container portion, thus allowing the bottom frame-fixed pallet to have therein vertically free spaces through which the tines of a cargo-handling plunger may move, and (B) the container portion comprising loose wall boards for the side and end walls of the container portion, the loose wall boards being demountably erected in edge to edge relation within said bottom frame along the vertical side thereof, and easily releasable means to hold the erected loose wall boards together in position, whereby the container can easily be assembled for shipping and disassembled as a bundle of the component members of compact size for being sent back to the user for repeated use.

Claim 5

A simplied container construction including a bottom frame-fixed pallet portion and a container portion mounted thereon, (A) the bottom frame-fixed pallet portion comprising (1) a pallet composed of spaced parallel base boards, spaced parallel runners fixed on the base boards transversely thereof, longitudinal boards fixed on the runners longitudinally thereof and spaced parallel transverse boards fixed on the longitudinal boards transversely thereof and just above the base boards respectively, and (2) a rectangular bottom frame having a L-shaped cross section and fixed on the pallet for receiving the container portion, thus allowing the bottom frame-fixed pallet to have therein vertically free spaces through which the tines of a cargo-handling plunger may move, and (B) the container portion comprising loose wall boards for the side and end walls of the container portion, the loose wall boards being demountably erected in edge to edge relation within said bottom frame along the vertical side thereof, and easily releasable means to hold the erected loose wall boards together in position, whereby the container can easily be assembled for shipping and disassembled as a bundle of the component members of compact size for being sent back to the user for repeated use.

Claim 6

A simplified container construction according to claim 3, wherein the runners have downwardly sloped ends and the longitudinal boards extend beyond the upper edges of the sloped ends of the runners thereby forming therebetween a recess through which ropes may be passed for loading or unloading the container.

Claim 7

A simplified container construction according to claim 3, the container portion further comprises a bottom board demountably placed within the bottom frame on the bottom frame-fixed pallet.

Claim 8

A simplified container construction according to claim 4, wherein the container portion further comprises a bottom board demountably placed within the bottom frame on the bottom frame-fixed pallet.

Claim 9

A simplified container construction according to claim 3, wherein the easily releasable holding means are pack tapes wound around the erected loose wall boards.

Claim 10

A simplified container construction according to claim 3, wherein the container portion further comprises both upper wall edge frames covering the upper edges of the erected wall boards and vertical wall edge frames covering the vertical edges of the wall boards, with the upper ends of the vertical wall edge frames being covered by the upper wall edge frames and the lower ends thereof covered by the bottom frame.

Claim 11

A simplified container construction according to claim 8, wherein the upper wall edge frames are in the form of a unitary rectangular wall edge frame thereby serving as a means to securely hold the loose wall boards together in position.

Claim 12

A simplified container construction according to claim 8, wherein the upper wall edge frames are locked with one another by suitable locking means so that they take a form like a unitary rectangular upper wall edge frame, thereby serving as a means to securely hold the wall boards together in position.

Claim 13

A simplified container construction according to claim 3, wherein the rectangular bottom frame has an outward projection at at least one end of each side and wherein channel-shaped upper wall edge frames having at one end a projection and at the other end a L-shaped cut in which the projection-provided end of the adjacent upper wall edge frame is inserted, and cross-sectionally L-shaped vertical wall edge frames covering the vertical edges of the wall boards and having a hole at the upper end and at least one hole at the lower end are additionally used in such a manner that the projection of the upper wall edge frames is inserted in the corresponding hole provided at the upper end of the vertical wall edge frames and the projection of each side of the bottom frame is inserted in the corresponding hole provided at the lower end of the vertical wall edge frames to securely hold the loose wall boards together in position with aid of the easily releasable holding means.

Claim 14

A simplified container construction according to claim 3, wherein the erected loose wall boards are covered at each vertical edge with channel-shaped vertical wall edge frames in such a manner that the vertical edge is inserted in the recess of the frame.
