AI Technical Summary

Problems solved by technology

There is no folding line on the dividing line between the base and the side walls of some existing containers. When in use, the shape of the base is curved, and the container cannot be placed smoothly.
[0006] Existing collapsible containers generally do not have handles, even if they have handles, other connecting devices are required to fix them, or the handles have a single purpose and cannot simultaneously stabilize the container

Embodiment 1

[0042] Example 1: Please refer to the attached figure 1 , Which shows the blank 10 in an unfolded planar state, which is composed of a plastic sheet or a similar foldable sheet material, the blank 10 is provided with a plurality of fold lines scribed into the sheet body, along the The folding line folds the material, which can deform the blank 10 from the flat state to the attached Figure 2a To the container 90 shown in c.

[0043] The edge of the blank 10 has two opposite sides 20, 30 and the other two opposite sides 40, 50. The sides are generally composed of four hypotenuses 28a to d and four tabs 19a to d. The sides of the "U" shape meet.

[0044] A first fold line 16 (a to d) and a second fold line 17 (a to d) respectively extend from both ends of a hypotenuse 28 (a to d) to the blank 10, depending on the situation. The joints 21 (a to d), the joints 21a to d are positioned such that when folded into use, the area between the joints 21a to d is sufficient to form a base 39 t...

Embodiment 2

[0054] Embodiment 2: Please refer to the attached Figure 4 , Which shows the blank 110 in an unfolded flat state, the blank 110 and figure 1 The description of the corresponding parts of the blank 10 of the first embodiment shown is basically the same, and the same reference numbers are used to denote the corresponding parts. Therefore, only the differences are described in detail now.

[0055] The blank 110 and attached figure 1 The difference of the shown blank 10 is that the blank 110 also includes two opposite handle pieces 60a and 60b, which can be folded into a container with handle 190 (see Figure 5 ). In this embodiment, the first handle piece 60a protrudes outward from the edge of the first side wall 22 and is hinged to the edge of the first side wall 22 along a curved fold line 91a, and the first handle piece 60a has a curved edge. In a meniscus shape, the two ends of the curved edge coincide with the two ends of the curved fold line 91a respectively; the second handle...

Embodiment 3

[0058] Example 3: Please refer to the attached Figure 7 , Which shows the blank 210 in an unfolded flat state, the blank 210 and figure 1 The description of the corresponding parts of the blank 10 of the first embodiment shown is basically the same, and the same reference numbers are used to denote the corresponding parts. Therefore, only the differences are described in detail now.

[0059] The blank 210 and the attached figure 1 The main difference of the blank 10 shown is that the blank 210 also includes two opposite handle pieces 70a and 70b. Each of the two handle pieces is basically similar and is shown with the same reference number plus a different letter. Only the first handle piece 70a will be described in detail. The first handle piece 70a is hinged to the edge of the first side wall 22 along two curved fold lines 71a and 72a. The adjacent ends of the two curved fold lines 71a and 72a are connected by a curved cutout 73a, so The curved cutout 73a protrudes outward fro...

Abstract

The invention provides a foldable container (190) and the blank thereof, which comprises foldable sheet material, wherein, the blank can be folded into a container under a plane condition. The container (190) comprises a substrate (39), four side walls (22, 33, 44, and 55), four angle parts (20a to d) and two opposite handles (60a and 60b). The container (190) is provided with an opposite foldingline (47), and when the container (190) is under the plane condition, the foldable sheet material on the both sides of the opposite folding line (47) can be oppositely folded and coincided basically.The substrate (39) is provided with a bearing surface (92) formed by a quadrangular folding line frame, and a fourth folding line (18) is extended from each angle (93) of the quadrangular folding line frame, to limit the substrate (39) into a three-dimensional shape with five planes.

Description

【Technical Field】 [0001] The invention relates to a foldable container and its blank, in particular to a foldable container and its blank completely composed of a plastic sheet or similar foldable sheet material, the blank can be folded from a flat state to a use state Of the container. 【Background technique】 [0002] Under the existing technical conditions, there are many examples of containers folded from a blank made of a sheet of material. Such containers generally include a base and four side walls, and two adjacent side walls have a pair of equal bottom corners. The triangular webs of each pair are connected together, and each pair of adjacent webs is folded in half along the folding line between them and leaned against the side walls, so that the side walls stand on the periphery of the base, thereby forming a container in use. [0003] Generally, the various components of the existing container are connected in a hinged manner along the folding line. For example, an exampl...
