The present invention concerns a returnable case comprising a bottom member 1, left and right side members 2L, 2 R and front and back side members 3F, 3B, wherein the front and back side members 3F, 3B are formed foldable inward in a two fold state to the bottom member 1 and, in addition, formed to
The present invention concerns a returnable case comprising a bottom member 1, left and right side members 2L, 2 R and front and back side members 3F, 3B, wherein the front and back side members 3F, 3B are formed foldable inward in a two fold state to the bottom member 1 and, in addition, formed to be detachable. A pair of claw insertion openings 1f are provided on the bottom member 1, and the width (breadth) thereof is formed wide, and at the same time, the lower part of the member forming the claw insertion opening 1f is opened. Thereby, it can be loaded not only by the fork lift but also by the hand lift. The left and right side members 2L, 2R and front and back side members 3F, 3B are joined by a lock member 4.

What is claimed is: 1. A returnable case, comprising a bottom member, left and right side members provided foldable inward in regard to the bottom member, and front and back side members detachable in regard to the bottom member and formed two-foldable taking the longitudinal direction as a boundary, in which contact ends of said left and right side members and said front and back side members are disposed enabling to look and unlock by a lock member, wherein said front and back side members are formed foldable inward by pivotally supporting respective lower ends with the bottom member, wherein said front and back side members have a pair of engagement bars attached to the lower end, and when the engagement bars are fitted to a pair of supporting reception members provided on said bottom member, the front and back side members can rotate by taking the supporting reception member as a fulcrum, and when the engagement bars are removed from the supporting reception member, the front and back side members can be extracted from the bottom member, and wherein for the pair of engagement bars attached to the lower ends of said front and back side members, the length of any one of engagement bars is set shorter than the length of the other engagement bar. 2. The returnable case of claim 1, wherein said lock member has a slide bar attached to the ends of the front and back side members through a retention member, and a bent portion disposed at the tip of the slide bar, said lock member is formed to jock by passing the bent portion through an engagement long hole disposed on a vertical frame member of the left and right side members and, at the same time, axially rotating the slide bar by 90 degrees, and to unlock by axially rotating the slide bar by 90 degrees in the opposite direction from the locked state and extracting the same from the long hole, and wherein said retention member is provided with a fixation portion at both ends of said retention member to which a spring action is afforded and the slide bar is formed enabling to fit or to detach from the fixation portion. 3. The returnable case of claim 1, wherein a wheel is composed to be able to be mounted detachably, for a corner fitting fixed to the outside of an edge corner of said bottom member, and wherein a hole is formed on the corner fitting fixed to the outside of the edge corner of said bottom member and a colored insertion portion is installed at an upper end of a vertical frame member for the left and right side members, allowing to view the colored insertion portion from the exterior through said hole, when returnable cases are stacked up with the insertion portion inserted in said corner fitting. 4. A returnable case, comprising a bottom member, left and right side members provided foldable inward in regard to the bottom member, and front and back side members detachable in regard to the bottom member and formed two-foldable taking the longitudinal direction as a boundary, in which contact ends of said left and right side members and said front and back side members are disposed enabling to lock and unlock by a lock member, wherein said front and back side members are formed foldable inward by pivotally supporting respective lower ends with the bottom member, wherein said lock member has a slide bar attached to the ends of the front and back side members through a retention member, and a bent portion disposed at the tip of the slide bar, said rock member is formed to lock by passing the bent portion through an engagement long hole disposed on a vertical frame member of the left and right side members and, at the same time, axially rotating the slide bar by 90 degrees, and to unlock by axially rotating the slide bar by 90 degrees in the opposite direction from the locked state and extracting the same from the long hole, and wherein said retention member is provided with a vertical substrate and bent pieces erected at both ends thereof, a socket made of silicon rubber is fixed to the lower part of the vertical substrate, a fixing portion of the slide bar is composed of the socket and said bent piece, and the slide bar is formed to be able to fit or detach the slide bar to or from the fixing portion.
