Description

[Detailed description of the invention] This invention relates to an improvement of a container with four equal partitions, which has a continuous partition wall on the bottom wall.

Attach the partition wall to the bottom wall in a row through the folded line, attach the required adhesive parts to make a box body, and when not in use, fold it flat to reduce the bulk, and when in use, attach the four parts to the bottom wall. Containers with partitions that can be repeatedly divided into four equal parts are becoming popular in a box body in which partition walls are divided into equal parts.

However, this container with quarter partitions can turn a folded flat body into a box in one movement for storing goods, but the partition walls inside the box automatically turn into a cross shape. It is quite a hassle, as you have to insert your hand and bend the horizontal partition wall that connects to the vertical partition wall at right angles, and even if you make it into a cross shape, it will return due to the elasticity of the material, so you need to make adjustments. There is a drawback that it takes

The purpose of this invention is to solve the problems mentioned above.

In other words, this idea is designed so that the bottom wall connected to the end wall is in contact with the horizontal partition wall that should be bent, and the partition wall on the bottom wall is automatically shaped into a cross shape with a single movement. It is a container with partitions divided into four equal parts, making it both stable and stable.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The container with quarter partitions of this invention is formed from thick paper such as cardboard, as shown in the developed view shown in Fig. The side wall 3 and the end wall 4 are sequentially taken out, and a broken line 5 is formed on the lower edge of the opposing side wall 3.
A substantially rectangular bottom wall 6 is continuously installed through the opposing end wall 4.
An inverted triangular bottom wall 7 with a rounded tip is continuously attached to the lower edge of the bottom wall 6 via a fold line 5, and a rectangular vertical partition wall 9 is attached via a fold line 8 from the left end of the lower edge of the bottom wall 6. , a rectangular horizontal partition wall 11 is provided on the right edge of this vertical partition wall 9 and extends along a fold line 10, and an upper lid wall 1 is provided on the upper edge of the side wall 3.
2, a lower cover wall 13 is continuously attached to the upper edge of the end wall 4.

The bottom wall 6 has a vertical width approximately % longer than the width of the end wall 4, and is provided with a triangular adhesive portion 15 at the right end defined by a 45° diagonal fold line 14 passing through the upper right corner. .

The bottom wall 7 has the polygonal line 5 as its base, and has a base angle α1 of approximately 70
', α2 are set to approximately 60°, and the tip is formed into an inverted triangular shape with a curved portion A having a required radius of curvature at the apex corner of the tip, and the length from the fold line 5 to the tip is approximately % of the width of the side wall 3.

The vertical partition wall 9 has a fold line 8 at the upper edge that is approximately % of the width of the side wall 3.
A polygonal line 10 that is perpendicular to the polygonal line 8 with the right end of the polygonal line 8 as the intersection point.
Horizontal partition walls 11 are connected to each other via.

The horizontal partition wall 11 is adjacent to the bottom wall 6 via a cut line 16 extending straight from the right end of the fold line 8.

Note that it is preferable that the heights of both the partition walls 9 and 11 when erected match the heights of the side walls 3.

When assembling the container with quarter partitions according to this invention, first, the horizontal partition wall 11 and the vertical partition wall 9 are assembled along the fold line 10.
, the vertical partition wall 9 is bent along the fold line 8, the bottom wall 6 is folded along the fold line 5, and then the side wall 3° 3 and the end walls 4, 4 are folded and pasted along the fold line 1. A box body is made by pasting the cloth piece 2 to the end wall 4.

Further, the adhesive part 15 of the bottom wall 6 is reversely folded along the diagonal fold line 14, and the bottom wall 7 is bent at right angles along the fold line 5 while inserting the bottom wall 7 inside the bottom wall 6. is folded back and pasted on the outer surface of the bottom wall 7.

Finally, by bending and joining the lower cover wall 13 of the upper opening and the upper cover wall 12, a completed assembly of this invention as shown in FIG. 2 is completed.

As shown in FIGS. 3 and 4, this container with four equal partitions has a bottom wall 7 attached to the top surface of the adhesive part 15 of the bottom walls 6 and 6 that face each other.
The bottom walls 6 and 7, which abut each other, are overlapped and adhered to each other, and the bottom walls 6 and 7, which abut each other, are alternately overlapped and locked to form a stable bottom surface.
A cross-shaped partition in which the horizontal partition wall 11 and the horizontal partition wall 11 are perpendicular to each other is automatically created.

In order to make the container with quarter partitions into a flat body when not in use, as shown in FIGS. When corner B (see the arrow in Fig. 6) in the direction intersecting the axis is pressed together, it is folded in half along the diagonal fold line 14 and retracted, and the engagement between the bottom walls 6 and 7 is released. It becomes a flat body with one action.

When this container with four equal partitions is pulled apart by holding the arrow corner B, the curved tip A of the bottom wall 7, which is standing up about the fold line 5, engages with the lower end of the horizontal partition wall 11. C, push it and bend it at right angles to the vertical partition wall 9, and even after the box is formed, the tip of the bottom wall 7 is aligned with the horizontal partition wall 1.
Since it abuts against the lower edge of 1, the cross-shaped partition can be maintained at all times.

In addition, in the container with quarter partitions, the width of the side wall 3 is equal to the width of the end wall 4.
The shape of the substantially triangular bottom wall 7, that is, the base angles α1 and α2, corresponds to the aspect ratio of the bottom surface.
The radius of curvature of the curved end portion A can be appropriately selected so as to easily abut against the horizontal partition wall 11.

The container with quarter partitions according to this invention has the structure and function as described above, and when not in use, it can be folded into a flat body, and when in use, it can be turned into a box with quarter partition walls. This can be done extremely easily and repeatedly, and when making a box, there is no need to make any changes to make the partition walls cross-shaped like in conventional products. Since the lower end of the horizontal partition wall that connects to the rectangular bottom wall is pressed, bent, and abutted, there is no possibility that the horizontal partition wall will return due to the elasticity of the material, unlike conventional products.
The cross-shaped partition wall is stable and has the effect of improving the efficiency of packing the goods into boxes.
