Container with sealable band

Claim 1

A container with a sealing band being composed of a single foldable plate member and a sealing band member, the plate member being provided with: concave fold lines forming a bottom plate portion in the shape of a substantially equilateral polygon in the center of the plate member, radial concave fold lines radially extending from respective vertexes of the bottom plate portion, intermediate fold lines each consisting of a concave segment and a convex segment connecting intermediate points of adjacent ones of said radial concave lines; first convex fold lines inclined by an angle α with respect to the radial concave fold lines and connected between the respective vertexes of the bottom plate portion and the junctions of the concave and convex segments of the intermediate fold lines, and second convex fold lines inclined in the same direction as the first convex fold lines by an angle greater than the angle α with respect to the radial fold lines and connected between the respective junctions of the concave and convex segments of the intermediate concave fold lines and the outer edge of the plate member; the sealing band member including a bottom belt portion formed in the shape of a rectangle having four vertexes which positionally correspond to two pairs of said vertexes on opposite sides of the bottom plate portion, two side belt portions formed in the shape of rectangles, four vertexes of each side belt portion positionally corresponding to one pair of said vertexes on the bottom plate portion and neighboring intermediate points of the radial concave fold lines of the folded foldable plate member, a top belt portion in the shape of a rectangle having four vertexes which positionally correspond to the two pairs of neighboring intermediate points of the radial concave fold lines on opposite sides of the folded foldable plate member, wherein the intermediate concave folded lines and the second convex fold lines are perforated, wherein said side belt portions are inclined by an angle γ with respect to said top and bottom belt portions, and wherein said side belt portions are each connected to at least one of said bottom and top belt portions along lines connecting respective pairs of said vertexes, and wherein the lines connecting respective pairs of said vertexes at a joinder of each of said side belt portions with said bottom portion are non-parallel with the lines connecting respective pairs of said vertexes at a joinder of said side belt portions with said top portion.
