Torsion-type container

Abstract

To provide a torsion-type container that solves such a problem that a conventional container must be torn or ripped apart when removing a packaged item from the container and as the container, when in soft package material, stretches and is hard and time-consuming to tear, while the container, when being a box made of hard packaging material, a cutting tool is required, making opening the box time-consuming and also making disposing of the empty box difficult.SOLUTION: The torsion-type container includes: a mount (1); contents (2) held on the mount; and a shrink film (3) that heat-shrinks the mount (1) and the contents (2) to integrally package them. The mount has a portion to be twisted (4) in the transverse direction, and the shrink film also has a portion to be twisted (5) at a position corresponding to the portion to be twisted. When the two side portions in the opposite directions across the portions to be twisted (4, 5) are twisted, the portions to be twisted are broken, allowing the contents to be removed.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to a shear-type container that can be easily broken to take out the contents by twisting the container, that is, by applying a couple to both ends of the portion to be sheared of the container.

Background Art

[0002] It is known to provide a shrink-wrapped body with a base paper having excellent stability of the wrapped article by reducing the occurrence of shrinkage unevenness and improving the adhesion between the heat-shrinkable compatible resin film, the base paper, and the wrapped article (Japanese Patent Application Laid-Open No. 7-251859).

[0003] According to the description in paragraph 0008, paying attention to the fact that shrinkage unevenness (wrinkles), the adhesion between the heat-shrinkable compatible resin film, the base paper, and the wrapped article, and its stability are closely related to the shrinkage rate in the longitudinal direction and the shrinkage rate in the width direction when the wrapped article and the base paper are integrally packaged, the present invention was completed by specifying these shrinkage rates in the longitudinal direction and the width direction, and it is only focused on specifying these shrinkage rates.

Summary of the Invention

Problems to be Solved by the Invention

[0005] What is disclosed in Patent Document 1 specifies the shrinkage rate of the heat-shrinkable synthetic resin film in relation to the wrapped article and the base paper, and there is no mention or suggestion regarding the breakage of the container.

[0006] To take out the wrapped article in the container, it is necessary to break or tear the container. However, in the case of a flexible packaging material, since it is elastic and stretches, it is difficult to break and it takes time. In the case of a box made of a rigid packaging material, a cutting tool is required, so it takes time to open it, and it is also troublesome to handle the empty box.

Means for Solving the Problems

[0007] (Claim 1) The shear-type container according to the present invention is composed of a base paper, a content held on the base paper, and a shrink film that heat-shrinks these base paper and content and wraps them integrally. And, a shear-predetermined portion is provided in the transverse direction on the base paper, and a shear-predetermined portion is also provided at a position corresponding to the shear-predetermined portion on the shrink film.

[0008] With the content held on the base paper, the shrink film is heated and shrunk. As a result, the content is wrapped in a stationary state together with the base paper. When taking out the content, sandwich the shear-predetermined portion of the shear-type container and hold both sides with separate fingers, and press both ends of the shear-predetermined portion in opposite directions, that is, in the direction of the couple force, then the shear-predetermined portion can be easily broken and the content can be taken out.

[0009] (Claim 2) The base paper may be composed of a rectangular flat plate, a base portion having a holding hole for the content, a back portion formed by folding both side edges of the base portion along a fold line to the back side of the base portion and integrating them to close the back of the holding hole, a hanging portion with a through hole protruding from one end of the base portion and bent along a fold line, and a bottom cover protruding from the other end of the base portion and folded back to the base side. In this way, the content is stably held on the base paper.

[0010] (Claim 3) The content may be in pressure contact with at least both side hole edges of the back portion and the holding hole by the shrinking force of the shrink film. In this way, the content is stably held on the base paper and does not shift in position even during movement or transportation.

[0011] (Claim 4) Shear-introducing portions may be provided at both ends of the shear-predetermined portion on the shrink film. In this way, it becomes easy to specify the breaking location.

Advantages of the Invention

[0012] According to the shear-type container of the present invention, it is composed of a mount, the contents held on the mount, and a shrink film that heat-shrinks and integrally wraps these mount and contents. The mount is provided with a shear-predetermined portion in the transverse direction, and the shrink film is also provided with a shear-predetermined portion at a position corresponding to this shear-predetermined portion. Therefore, by holding both sides of the shear-predetermined portion of the shear-type container with separate fingers and applying forces in opposite directions, that is, in the direction of the couple force, the container can be easily broken along the shear-predetermined portion, and the contents can be taken out.

Embodiment

[0014] Hereinafter, an embodiment of the shear-type container according to the present invention will be described. (Claim 1) In FIGS. 1 to 3, the shear-type container according to the present invention is composed of a mount 1, the contents 2 held on the mount 1, and a shrink film 3 that heat-shrinks and integrally wraps these mount 1 and contents 2.

[0015] The mount 1 is provided with a shear-predetermined portion 4 in the transverse direction, and the shrink film 3 is also provided with a shear-predetermined portion 5 at a position corresponding to this shear-predetermined portion 4.

[0016] When taking out the contents 2, do as shown in Fig. 5. That is, hold the upper part 20 and the lower part 21 with separate fingers, sandwiching the planned shearing parts 4 and 5 of the shear-type container, and twist them in opposite directions, i.e., the couple direction, as indicated by the solid or dashed arrows. In this way, the upper and lower parts 20 and 21 are each sheared at the planned shearing part 4 of the mount 1 and at the planned shearing part 5 of the shrink film 3, so that the contents 2 can be easily taken out.

[0017] (Claim 2) Fig. 4 is a developed view of the mount 1, which is composed of a rectangular flat plate, and includes a base 7 having a holding hole 6 for the contents 2, fold lines 8 and 9 provided at the side edges of the base 7, a back part 10 that is bent and integrated on the back side of the base 7 by these fold lines 8 and 9 to close the back of the holding hole 6, a hanging part 14 that protrudes from one end of the base 7 and is bent by a fold line 11 with through holes 12 and 13 opened at opposite positions, and a bottom cover 15 that protrudes from the other end of the base 7 and is folded back to the base 7 side. In this case, the contents 2 are stably held on the mount 1.

[0018] (Claim 3) The contents 2 are adapted to be in pressure contact with at least both side hole edges 16 and 17 of the back part 10 and the holding hole 6 due to the shrinking force of the shrink film 3. In this case, the contents 2 are stably held on the mount 1 and do not shift in position even during movement or transportation.

[0019] (Claim 4) The shrink film 3 is provided with shearing introduction parts 18 and 19 at both ends of the planned shearing part 5. In this case, it becomes easy to specify the breaking location.
