Description

  The present invention is formed by variously forming folds at the center of a container such as a paper-like pack or a plastic bottle, and is manufactured with a structure that can be folded after use or as needed. The present invention relates to a volumetric deformation type deformable container that can reduce the volume of an empty container after use of the contents contained in the container and can reduce the volume at the time of recovery.

  Many containers with various forms for storing various contents such as drinks such as milk and medicines are found in the vicinity of daily life. Among these various containers, containers such as pack-type containers, plastic bottles, resin containers, etc. that take into consideration the convenience in use, the preservation of contents, the ease of production, the economy, etc. There are many.

  In the mid 1910s, a “paper bottle” was produced by an American citizen, and then in the 1950s, pack-type containers such as milk cartons of the structure currently in circulation were popularized. In addition, a light and durable PET bottle made of polyethylene resin is used as a building bottle as a substitute for a glass bottle. Such pack-type containers and PET bottles seem to have a simple structure, but are containers made possible by the development of technology, and there are various modes when there is no need to use existing heavy equipment. Such containers are widely used.

  However, such variously modified containers are a cause of natural and environmental destruction. In other words, milk cartons, whose main raw material is pulp, do not rot compared to general paper, and such problems are caused by PET bottles, whose main raw material is polyethylene resin that does not rot, and general resins. It stands out even more in the container.

  As interest in environmental issues increases, processed products made from such non-perishable raw materials are collected, and pack-type containers such as milk packs and plastic containers such as plastic bottles that are the subject of the present invention are also collected and recycled. It has become a big concern.

  However, in addition to collecting such a container, there is a problem that the size of the container cannot be reduced after the collection. Therefore, pack-type containers such as milk packs must go through a process of being collected in a form that is thinned after the necessary parts such as milk have been drunk and cut with hands or blades. Also, in the case of PET bottles, it took a lot of time and effort to collect, such as cutting the necessary parts with a blade.

  In order to solve the above problems, the object of the present invention is to form various folds at the center of a container such as a paper pack or a plastic bottle, unlike a conventional container of various forms, and after using the container, Or it is possible to reduce the volume of the container that is empty after the contents contained in the interior are lost by making it with a structure that can be folded during use as needed. Provided is a technique related to a volume contraction type deformation container capable of reducing the volume.

  In order to achieve the above-mentioned object, the volume-reduction type deformable container according to the first aspect of the present invention includes a number of folds that divide a folded portion of the container and a diagonal edge that is positioned between the number of folds. By forming a plurality of hatched folds, the volume of the container can be reduced by rotating the upper and lower portions of the container in accordance with the forming direction of the hatched folds.

  A volumetric deformation container according to a second aspect of the present invention is the volumetric deformation container according to the first aspect, wherein the deformation container is formed using any one of paper, pulp, pet, and resin as its material. And

  According to a third aspect of the present invention, there is provided a volumetric deformation type container according to the first aspect of the present invention, wherein the hatched fold is formed in an X shape.

  According to a fourth aspect of the present invention, there is provided the volumetric deformation container according to the first aspect of the present invention, wherein the hatched folds are formed in a diagonal line in one direction.

  According to a fifth aspect of the present invention, there is provided a volume-reduced deformation container according to the first aspect of the present invention, wherein the deformation container is formed with a large number of folding folds in the upper part of the container.

  The deformed container of the present invention makes it possible to reduce the volume of an empty container after using the contents contained therein, and dramatically reduces the volume at the time of collection, so that it can be carried and reused. This is expected to have a great influence on the prevention of environmental pollution.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a volume-reduced deformable container according to an embodiment of the present invention. In this embodiment, a milk pack in which a new structure is achieved by a technical concept of the present invention with respect to a general milk pack. Figure 3 shows a deformed container of a mold.

  FIG. 2 is a view for explaining the principle of contraction of a volumetric deformation container according to an embodiment of the present invention.

  As shown in FIG. 1, the milk pack type deformable container 10 according to the present embodiment has a number of step folds 101 for dividing the central portion of the deformable container 10 into which the contents are put into a necessary number of steps, that is, the deformed container 10. It is formed by shifting vertically. The number of folds 101 is formed in consideration of the initial size of the deformable container 10 into which the contents enter. In the present embodiment, there are two stages, but it may be one stage, three stages, or more as necessary.

  A large number of folds 102 are formed between the folds 101 to form a portion that is folded in order to reduce (contract) the volume. Further, in the present embodiment, the fold line 102 is formed in an X shape from the upper right to the lower left and from the upper left to the lower right by connecting the edges between the fold lines 101 as illustrated. As will be described later, such a fold 102 is for reducing the volume by rotating the volume-reduction type deformation container of the present embodiment in a necessary direction.

  Further, unlike the present embodiment, such a fold 102 can be formed in a deformed form one by one, that is, every fold 102 can be deformed from the upper left to the lower right or from the upper right to the lower left. It is. As described above, even when the deformable container 10 of the present embodiment is formed with such folds 101 and folds 102, when the contents are first put and used, a general case as shown in FIG. It becomes a pattern of a container having a rectangular parallelepiped volume such as a milk pack.

  On the other hand, after the contents have been drunk up, the container upper part 10u is placed in one direction (counterclockwise) in the center of the deformed container 10 as shown in FIG. By rotating in the clockwise direction, the size of the entire deformation container 10 can be dramatically reduced. Further, as shown in FIG. 2 (B), it can also be rotated in the opposite direction, and as a deformed form, when the fold line 102 is formed one by one, if it is rotated in the direction of the formed fold line 102, Similarly, the overall size of the deformable container 10 can be reduced.
