Description

  The present invention relates to an impact resistant container that is not easily damaged even when an impact is applied by dropping or the like.

  Various containers have been proposed that have been devised so that the contents will not come out of the container due to damage caused by dropping or the like. For example, in the technique described in Patent Document 1, an inner container that stores a stored item is stored in an outer container, and an elastic material is interposed between these containers, so that an impact is directly applied to the container disposed inside. It is supposed not to join.

  By the way, the container having the above-described configuration has a problem in that the number of parts increases and the number of assembling steps increases, and the manufacturing cost increases accordingly.

JP 2003-40276 A

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an impact resistant container that is less damaged when a shock is applied due to a drop or the like, and the number of parts and assembly processes are small.

  The present invention is an impact resistant container comprising a container main body and a lid attached to the container main body, wherein the container main body includes a storage portion for storing contents, and a periphery of the storage portion And an outer wall portion surrounding the container from all sides, and the bottom portion of the housing portion is provided at a position higher than the lower end portion of the outer wall portion, and the container body is supported by the outer wall portion. The object is achieved by providing a container.

  The impact-resistant container according to the present invention has a small number of parts and an assembling process, and can reduce the manufacturing cost. Moreover, since the container is not easily damaged when an impact is applied due to dropping or the like, leakage of contents accompanying the damage can be prevented.

The present invention will be described below based on preferred embodiments with reference to the drawings.
As shown in FIG. 1, an impact resistant container (hereinafter also simply referred to as a container) 1 of the present embodiment includes a container main body 2 and a lid 3 attached to the container main body 2.

  The container body 2 includes a storage portion 21 in which contents are stored, and an outer wall portion 22 that surrounds the storage portion 21 from four directions.

  The container body 2 has a mouth portion 20 that opens upward. A thread 201 for screwing the lid 3 is provided on the outer peripheral surface of the mouth portion 20.

  The accommodating portion 21 has a bottomed cylindrical shape that continues from the mouth portion 20. The bottom portion 211 of the housing portion 21 is provided at a position higher than the lower end portion 221 of the outer wall portion 22. For this reason, the container body 2 is supported by the outer wall portion 22. The height H (see FIG. 2) from the lower end portion 221 of the outer wall portion 22 to the bottom portion 211 of the housing portion 21 is set in consideration of preventing an impact from being directly transmitted to the bottom portion 211 of the housing portion 21.

  The outer wall portion 22 projects outward from between the mouth portion 20 and the accommodating portion 21 and extends further downward. A gap is provided between the accommodating portion 21 and the outer wall portion 22, so that an impact is not directly transmitted to the peripheral surface of the accommodating portion 21.

The outer wall portion 22 is opened at the lower end portion 221 and is provided so that the thickness decreases downward. If the thickness of the outer wall portion 22 is thinly provided downward, the outer wall portion 22 is likely to bend when an impact is applied due to dropping or the like, and the impact is further alleviated. In consideration of die cutting at the time of molding, it is preferable to mold so that the inner peripheral surface side becomes gradually thinner downward. In the present embodiment, as shown in FIG. 2, the outer wall portion 22 is formed so that the thickness of the outer wall portion 22 gradually decreases from both sides of the inner and outer peripheral surfaces of the outer wall portion 22 downward.
The thickness of the lower end portion 221 of the outer wall portion 22 is preferably 1.0 to 2.0 mm in consideration of stability when the container body is supported.

  The shape of the periphery of the outer wall portion 22 is a substantially square shape in plan view, and four corner portions 223 are formed between adjacent plate-like flat portions 222. The outer edge of each corner 223 is formed into an arcuate curved surface so as to suppress damage due to impact received at the corner 223.

  The container body 2 is an integrally molded body of synthetic resin. Examples of the constituent material of the container body 2 include synthetic resins such as polyethylene terephthalate and polycyclohexanedimethyl terephthalate.

  The lid 3 is assembled by fitting an inner lid 33 on the back side of the top surface portion 311 of the outer lid 31 via an elastic body 32. The shape of the periphery of the outer lid 31 is substantially square when viewed from the top like the shape of the periphery of the outer wall portion 22 of the container body 2, and the outer edge of each corner is formed into an arcuate curved surface. On the inner peripheral surface of the outer lid 31, a screw groove 311 that is screwed with the screw thread 201 on the outer peripheral surface of the mouth portion 20 is provided. The outer lid 31 and the inner lid 33 constituting the lid body 3 are each integrally formed of synthetic resin. In this embodiment, the outer lid 31 is a polypropylene molded body, and the inner lid 33 is a low-density polyethylene molded body. The elastic body 32 is a molded body of an elastic material such as rubber, and is a molded body of silicone rubber in this embodiment.

  The container 1 configured as described above has a small number of parts and an assembly process, and can reduce the manufacturing cost. In addition, since the outer wall portion 22 surrounding the housing portion 21 from four sides is provided, even when an impact is applied due to dropping or the like, the outer wall portion 22 absorbs the impact, and the impact can be directly transmitted to the housing portion 21. In addition, it is possible to prevent damage to the accommodating portion 21 and leakage of contents accompanying it.

The present invention is not limited to the embodiment.
The impact resistant container of the present invention is preferably molded so that the thickness of the outer wall portion 22 gradually decreases from both sides of the inner and outer peripheral surfaces of the outer wall portion 22 downward as in the above embodiment. The outer peripheral surface may be formed vertically, and the outer wall portion 22 may be formed so that the thickness of the outer wall portion 22 decreases from only the inner peripheral surface side downward.

  The impact resistant container of the present invention is not particularly limited in its use. Examples of the contents accommodated in the impact resistant container of the present invention include hair cosmetics.

It is a schematic diagram which shows one Embodiment of the container of this invention, (a) is a top view, (b) is a half sectional view, (c) is a bottom view. It is a partial expanded sectional view of the container main body of the embodiment.
