Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a paper container suitable for storing and selling confectionery, and more particularly to a designed box-shaped paper container in which the boundary between adjacent side surfaces forms a gentle arc.

[0002]

[Prior Art]

 In this type of box-shaped paper container, the boundary between the side surfaces, that is, the ridge line portion is usually folded at a right angle. However, from the viewpoint of design, a box-shaped container in which the boundary between adjacent side surfaces forms a gentle arc as described above has been conventionally provided. An example of a paper container of this type is shown in FIG.

The paper container of FIG. 1 is a hexahedral container composed of a top surface, a bottom surface and four side surfaces. This container has six corners 1 between each side. As is clear from the figure, no linear creases are formed between the pair of upper and lower corners 1, and instead, in the vicinity of each corner 1, a V-shaped crease is formed between adjacent side faces. a is formed. The V-shaped fold line a is composed of _two line segments a ₁ and a ₂ , and each line segment a ₁ and a ₂ extends so as to spread toward the adjacent side surface.

By forming the V-shaped fold line “a” as shown in FIG. 1, a gentle arc can be formed at the boundary between the side surfaces, and the box with a rounded and excellent design effect can be obtained. A pattern container is provided. That is, as shown in FIG. 3, by forming the V-shaped fold line a on the adjacent side faces 2 and 3 in the vicinity of each corner portion 1, these line segments a ₁ and a ₂ are used as boundaries. The side faces 2 and 3 are divided into three face parts A, B and C. Therefore, the boundary between the side surfaces 2 and 3 is formed by the surface portion B forming a gentle arc.

By the way, although this type of paper container is manufactured in an automated box making line, any of the line segments a ₁ and a _{2 of the} V-shaped crease a is between the side surfaces 2 and 3. Since it does not pass through the center, there are many distortions in the completed box. That is, as shown in FIG. 2, when the traveling direction of the box-making line is the direction of the arrow, the rear side line segment of each V-shaped folding line a, that is, the adjacent side face is formed along the line segment a _1. It is about to be done. In FIG. 2, the solid line indicates a paper container without distortion, and the alternate long and short dash line indicates the paper container in which both side surfaces are formed with the line segment a ₁ as a boundary to cause distortion.

[0006]

[Problems to be solved by the device]

 Therefore, the technical problem to be solved by the present invention is that even when a paper container is manufactured by an automatic box making line, no distortion occurs in the assembly of the paper container and the boundary between adjacent side surfaces is gentle. Another object of the present invention is to provide a paper container capable of forming a circular arc.

[0007]

[Means, actions, and effects for solving problems]

 In order to solve the above technical problems, the present invention provides a paper container having the following configuration.

That is, this paper container has Y-shaped folding lines between adjacent side surfaces in the vicinity of each corner formed between each side surface and the top and bottom surfaces, and each Y-shaped folding line is formed. The ruled line is characterized by a central line segment extending from each corner along the center between adjacent side faces and two line segments extending from the tip of the central line segment toward both sides in a V-shape.

According to the above configuration, in the box making process, the adjacent both side surfaces are basically formed along the center line of the Y-shaped crease formed at each corner. This prevents distortion in the assembly of the paper container. In addition, since there are V-shaped line segments formed by being connected to each center line segment, three face portions are formed as in the conventional example described according to FIG. 3, and adjacent side faces are formed. The boundary between them is formed into a gentle arc by the central surface part.

It is not necessary that the center line segment of each Y-shaped fold line is formed so long. The small length dimension ensures that adjacent side surfaces can be formed without distortion.

【Example】

 An embodiment of the present invention will be described in detail below with reference to FIGS.

The paper container according to the illustrated embodiment is a deformed hexahedral paper container in which the bottom portion is formed thinner than the top portion. FIG. 4 shows a blank 10 as a material for forming the paper container, and FIG. 5 shows the paper container in a state where the blank 10 is assembled.

In FIG. 4, 11 a to 11 d indicate four side surfaces. The side surface 11b on the right side in the drawing is adapted to be glued to a margin 11d 'formed by connecting to the side surface 11d on the left side. The top surface 12 is formed by the upper lid pieces 12a to 12e connected to the side surfaces 11a to 11d and the upper portion of the margin 11d '. On the other hand, the bottom surface 13 is formed by the bottom lid pieces 13a to 13e connected to the side surfaces 11a to 11d and the margin 11d 'as in the above. In the figure, the alternate long and short dash lines indicate folding lines, and the solid lines in the blank indicate cutting lines.

As is clear from FIGS. 4 and 5, adjacent side surfaces 11a, 11b: 11b, 11c in the vicinity of the top surface 12 and the bottom surface 13 and each corner portion 14 formed between the side surfaces 11a to 11d; A Y-shaped fold line b is formed on 11c, 11d; 11d; 11a. The center line component b ₁ extending along these respective Y-Orikei b is a side between the centers of adjacent from each corner 14 of, spread into a V-shape from the front end of the center line b ₁ toward both sides It is formed by _two line segments b ₂ and b ₃ extending vertically.

As shown in detail in FIG. 6, each line segment b₁Is a standard for folding the sides on both sides at their centers. That is, this center line segment b₁Is the bending reference line of the two surface parts A and C. On the other hand, this center line segment b₁V-shaped line segment b extending from the tip of₂ , b₃Divides both side surfaces into three surface portions A, B and C. That is, the boundary portion between the two adjacent side surfaces is formed into a gentle arc by the surface portion B 1. In Fig. 7, the center line segment b in Fig. 6₁Part of c₁Section and V-shaped line segment b₂, b₃Upper part c ₂ The cross section at and is relatively shown. As is clear from FIG. 7, c₁Part is c ₁ Compared to c₂It can be clearly seen that the portion, that is, the surface portion B forms a gentle arc.

As shown in the above embodiment, by forming a Y-shaped crease near each corner 14, that is, by forming the center line segment b ₁ , both adjacent side surfaces are accurately folded. It is possible to prevent the distortion of the assembled paper container by giving a bending reference and to form the V-shaped line segments b ₂ and b ₃ to form the boundary between both side surfaces into a gentle arc. Of. In this way, the above-described embodiment can achieve the intended technical problem of the present invention.
