Abstract

An erectable container having a polygonal bottom plate is formed in the center of a foldable board member and side plates which are integrally provided extending from each edge of the bottom plate, at least one of the side plates being made in a pentagonal form. The pentagonal side plate is provided with two fold lines connecting between the vertexes at each end of the edge corresponding to the bottom plate and the vertex which is not adjacent thereto. An adhesive tab is provided on either one of each pair of lateral edges of the side plates which are adjacent to each other when the sides of the bottom plate are folded, so that, when each of the side plates is erected, the adhesive tab may join the side plates.

Claims

1. An erectable container formed from a single foldable board member, said board member defining:

a polygonal bottom plate formed in a center of said board member;

pentagonal side plates each having an edge common with an edge of said bottom plate, said pentagonal side plates having a pentagonal form including five vertices, two of said vertices being at ends of said common edge, each said pentagonal side plate defining at least two fold lines, each of said fold lines being connected between one of said two vertices and a vertex of said pentagonal side plate which is not adjacent to either of said two vertices; and

trapezoidal side plates each having an edge in common with edges of said bottom plate, wherein said pentagonal and trapezoidal side plates alternate with one another;

adhesion tabs extending from fold lines at side edges of each of said pentagonal side plates;

folding tabs extending from fold lines at top edges of each said pentagonal and trapzeoidal side plates, opposite said common edge thereof;

wherein all of said fold lines have the same sense and said tabs can join said pentagonal and trapezoidal side plates when said board member is folded to erect the container, and

wherein said side plates are dimensioned such that said top edges thereof form a plane when said board member is folded to erect said container.

2. The erectable container of claim 1, wherein said bottom plate is rectangular.
