Claims

[Scope of Claim for Utility Model Registration] (1) A substantially trapezoidal folding bottom plate that is bendably provided adjacent to the inside of each of the even-numbered side plates forming the box body, with the fold line portion of the lower opening edge as the base; and a rectangular locking plate, and the folded bottom plate is disposed between an isosceles triangular area portion having the overlapping fold line as one of the hypotenuses through the overlapping fold line disposed at a diagonal position of the bottom surface when the side plate is assembled. The locking plate is formed with an equilateral triangular area portion, and the locking plate is formed into a substantially chevron shape having an apex angle at a desired angle at a fold line that overlaps with the overlapping fold line, so that the locking plate can be freely bent together with the folding bottom plate. A package characterized in that a substantially arc-shaped engagement tongue piece capable of engaging with each other is formed on the upper side, and the overlapping fold line and the fold line are formed to be longer than approximately 1/2 of the length of the diagonal line on the bottom surface. Upper bottom device of the container. (2) By adjusting the lengths of the overlapping fold line and the fold line to be longer than approximately 1/2 of the diagonal line on the bottom surface, the apex angle of the locking plate that is bent into a substantially chevron shape along the fold line can be adjusted to a desired angle. 2. The upper bottom device for a packaging container according to claim 1, wherein the upper bottom device is adjusted to have an adjustable width.
