Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a composite container including a combination of a metal cylinder and a synthetic resin container housed in the cylinder.

[0002]

[Prior art]

 As shown in FIG. 4, a conventional composite container used to store various liquids is composed of a metal cylinder 1 and a polyethylene container 2 housed in the cylinder 1. 2 is provided with a top plate 4 that fits on the upper end of the cylinder 1 at the upper end of the body 3 that is housed in the cylinder 1, and a bottom plate 5 that fits on the lower end of the cylinder 1 at the lower end, and the top plate 4 can be opened and closed freely. It has a structure in which a large mouth portion 6 and a small mouth portion 7 are provided, and a metal cylinder 1 holds the strength of the container 2 and maintains its shape.

[0003]

[Problems to be solved by the device]

 By the way, since the top plate 4 and the bottom plate 5 of the container 2 in the conventional composite container have a structure in which the peripheral wall for fitting the cylindrical body 1 is provided around the circular flat plate, when the composite container falls, There is a problem that the impact is directly transmitted to the top plate 4 and the bottom plate 5 fixed to the cylindrical body 1, and particularly, the plug portions of the large mouth portion 6 and the small mouth portion 7 provided on the top plate 4 are damaged.

Therefore, an object of the present invention is to provide a composite container capable of alleviating a shock given to a top plate and a bottom plate at the time of a fall and preventing occurrence of breakage of a spout part.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has an annular bent wall at a position near the outer peripheral portions of a top plate and a bottom plate of a synthetic resin container, and also surrounds the mouth of the top plate. This is a configuration in which the bent portion is annularly provided.

In this invention, the synthetic resin container may be made of polyethylene, and the top plate may have two openings surrounded by an annular bent portion.

[0007]

[Action]

 The synthetic resin container housed in the cylinder has an annular bent portion near the outer periphery of the top and bottom plates, and an annular bent portion surrounding the mouth of the top plate. In the case of a fall, the bending part can mitigate the impact generated on the top plate and the bottom plate and prevent the mouth part from being damaged.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 of the accompanying drawings.

As shown in FIG. 1, the composite container 11 is made up of a combination of a metal circular cylinder 12 and a synthetic resin container 13 housed in the cylinder 12. As shown in FIG. 2, a cylindrical body portion 14 made of polyethylene and housed in the barrel body 12, and a top plate 15 provided on the upper end of the barrel body 14 and fitted and fixed to the upper end of the barrel body 12, It is provided with a bottom plate 16 which is provided at the lower end of the body portion 14 and is externally fitted and fixed to the lower end of the cylindrical body 12, and a top plate 15 is provided with a large mouth portion 17 and a small mouth portion 18 which can be opened and closed by a plug. ing.

The top plate 15 and the bottom plate 16 of the container 13 are formed by surrounding a fitting portion for the cylindrical body 12 on the outer circumference of a circular plate-like portion, and the bottom plate 15 is shown in FIGS. 1 and 3B. As described above, bent portions 19 and 20 having a substantially semicircular cross section are annularly provided around the outer peripheral portion and the intermediate portion.

Further, as shown in FIGS. 1, 2 and 3A, a bent portion 21 having a substantially semicircular cross section is annularly provided around the top plate 15 at a position near the outer peripheral portion, and a large opening 17 is further provided. Bent portions 22 and 23 are annularly provided at positions around the circumference and the edge portion 18, respectively.

The composite container of the present invention is constructed as described above, and the container 13 made of polyethylene is housed in the cylindrical body 12, and the top plate 15 of the container 13 is externally fitted and fixed to the upper end of the cylindrical body 12. The bottom plate 16 is externally fitted and fixed to the lower end of the cylindrical body 12.

Bent portions 19, 20 and 21 are provided on the top plate 15 and the bottom plate 16, and bent portions 22 and 23 are provided so as to surround the large mouth portion 17 and the small mouth portion 18 provided on the top plate 15. Since the container is provided in an annular shape, when the composite container 11 falls down, even if an impact is applied to the top plate 15 and the bottom plate 16, each bent portion extends and absorbs the impact, and the large mouth portion 17 and the small mouth portion 18 are damaged. Can be effectively prevented.

[0014]

[Effect of device]

 As described above, according to the present invention, since the annular bent portions are provided near the outer peripheral portions of the top plate and the bottom plate of the synthetic resin container and around the mouth portion provided on the top plate, the composite container does not fall. Occasionally, the impact applied to the top plate and the bottom plate can be alleviated by the extension of the bent portion, and the occurrence of damage to the mouth provided on the top plate can be prevented.
