Description

[Detailed description of the invention] This invention relates to a box that can be transformed from a rectangular cylinder into a hexagonal cylinder by modifying the side and bottom surfaces.

Conventionally, this type of box has been known as a container for bar-shaped sweets, granular sweets, etc., and as shown in FIG. A vertical fold line 5 and a chevron fold line 6 are provided on the side wall 1 of a flat rectangular cylindrical body a consisting of a wall 4, and a center fold line 7 is provided on the bottom wall 3, and the lid wall 4 is separated from the separation band 8, for example, or after opening, As shown in FIG. 2, there was one that could be transformed into a hexagonal cylinder b by pushing up the bottom wall 3. Such a box has a rectangular parallelepiped shape during transportation, which has good transportation efficiency, and once it reaches the consumer, it can have a hexagonal cylindrical shape, which has the advantage of making it easy to insert one's hand through the opening.

However, in this box, if it is made into a hexagonal cylinder,
Since the bottom wall 3 is not flat, it has a drawback that it tends to fall over when placed on a table or the like.

The purpose of this invention is to eliminate the above-mentioned drawbacks.

That is, this idea provides a pair of side walls with a vertical fold line, combines three pairs of bottom lid walls that slide flat to form a variable bottom surface, and converts a rectangular cylinder with an upper opening into a hexagonal cylinder by one action. It is a box that can be transformed.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. As shown in FIG. 3, the box of this invention has wide opposing side walls 11 and opposing narrow end walls 12, which are formed by bending a single expandable substrate C (see FIG. 4). , a vertical fold line 14 is provided at the center of the side wall 11 of the flat rectangular cylindrical body A consisting of a variable bottom surface (details will be described later) and a lid wall 13, and a series of opening cuts consisting of two cuts adjacent to the lid wall 13. A detachment band 15 is provided, and the variable shape is made possible by a combination of three pairs of opposing bottom lid walls (details will be described later) extending from the six sides of the lower edge of the cylinder so that it can be transformed into a hexagonal cylinder B (see Fig. 6) after opening. A bottom surface 16 (see FIGS. 5 and 6) is provided.

Note that this box does not necessarily require the separation band 15, and the lid wall 13 may be made into a separate lid body, or the lid wall 13 may be folded back to the side wall 11 side after opening using an appropriate opening means. good.

As shown in FIG. 4, the substrate C has a wide opposing side wall 11, an opposing narrow end wall 12, and a gluing margin 17 that are coupled laterally, and the side wall 11 and the end wall 1
A lid wall 13 and a folding piece 18 are connected to the upper edge of 2,
A vertical fold line 14 is provided in the center of the side wall 11,
The lower edge of the side wall 11 is divided by a fold line 19 and the lower end of the vertical fold line 14, and a substantially trapezoidal middle bottom cover wall 20 that becomes wider toward the tip and a substantially triangular lower bottom cover wall 21 that becomes narrower toward the tip are interconnected. A rectangular upper bottom cover wall 23 having an overlapping margin 22 (see details in FIG. 5) at the tip is connected to the lower edge of the end wall 12 via a fold line 19, and the upper end of the side wall 11 and the end wall 12 A series of separation strips 15 consisting of two cuts are provided.

The middle bottom cover wall 20 and the bottom bottom cover wall 21 are partitioned by a diagonal cut line 24 starting from the intersection X of the vertical fold line 14 and the fold line 19, and have rounded peripheral corners. A triangular notch 25 is formed in the middle bottom lid wall 20 at the edge opposite to the diagonal cut line 24, and a triangular notch 25 is formed in the bottom bottom lid wall 21 at the edge adjacent to the top bottom lid wall 23. A semicircular locking piece 27 that bites into the upper bottom cover wall 23 is continuous. This locking piece 27
There are recesses 28 at both ends along the fold line 26 to prevent slipping out.
is provided.

The upper bottom cover wall 23 is provided with a substantially sector-shaped engagement portion, which is a through hole 29 for inserting the locking piece 27, around the corner Y of the end wall 12 adjacent to the fold line 19 and close to the locking piece 27. ing. The width l of the through hole 29 is formed to match the length l of the neck on the fold line 26 of the locking piece 27, and
A locking piece 27 and a notch 3 for insertion are located adjacent to 9.
0 is set.

When assembling the box by bending it from a patterned board C, the glue allowance 17 is glued along the inner edge of the end wall 12 to form a rectangular cylinder A, and as shown in FIG. When the upper bottom lid wall 23 is folded in from the fold line 19, the overlapping margin 22 overlaps at the center of the bottom surface, and when the pair of middle bottom lid walls 20 are folded downward, their tips also overlap somewhat, and When the lower bottom lid wall 21 is folded downward and the continuous locking pieces 27 are made to stand up and inserted into the through-holes 29 of the upper bottom lid wall 23 and locked and secured, the variable bottom surface 16 is completed, and the folding pieces 18 are folded after storing the item. The packaging is completed by folding the lid wall 13 and gluing them together with an adhesive.

The variable bottom surface 16 of the box is constructed by folding in the middle bottom cover wall 20 first, then folding the top bottom cover wall 23 downward, and finally folding in the bottom bottom cover wall 21.
You can also assemble.

The box according to this invention has the above-described structure, and when used, the upper part is opened by tearing the separation band 15, etc., and the opposing end walls 12 are pressed together, and the sixth box is opened. As shown in FIG. 7 and FIG. 7, as the paired upper bottom lid walls 23 approach each other and the overlap increases, the wide side wall 11 folds in half from the vertical fold line 14, and the middle bottom lid wall 20 slides along with the side wall 11. The oblique side 24' formed by the diagonal cut line 24 comes into contact with one inner surface of the broken side wall 11 and stops, and at the same time, the lower bottom cover wall 21 slides along with the broken side wall 11, and the locking piece 27 is inserted into the through hole 29. can be transformed into a stable hexagonal cylindrical body B by sliding and abutting the other end and abutting the notch 25 of the inner bottom cover wall 20. Note that this hexagonal cylinder B can be restored to the square cylinder A in one action by pressing the two folded side walls 11 together to form a flat plate.

As mentioned above, according to the box of this invention, in order to create a hexagonal bottom surface, three pairs of opposing bottom cover walls are slidably overlapped and engaged, and a square tube can be formed by one operation. Since the body can be transformed into a hexagonal cylindrical body and the bottom surface remains flat, it is easy to insert a hand through the upper opening and can be placed stably on a table or the like.
