Composite container

Abstract

[Problem] It is an object to provide a composite container in which a shape and a profile of a resin hollow molding body can be discriminated with clarity in the case in which a visual contact is carried out to the inside resin hollow molding body via an outside transparent resin sheathing body, whereby a design property can be displayed to a satisfactory extent, and in which a design property can be displayed to a satisfactory extent even by a combination of the resin hollow molding body and the outside transparent resin sheathing body.[Means for Resolution] A composite container comprises a hollow molding body (a) made of a resin having a hollow inside and a highly transparent resin sheathing body (b) that has been integrated with an outside of the hollow molding body (a), wherein as a thickness of the highly transparent resin sheathing body (b) for a cross section in a horizontal direction getting across the hollow molding body (a) and the highly transparent resin sheathing body (b) at the major portion of the composite container, a minimum thickness (X) of the highly transparent resin sheathing body (b) is at least 0.1 mm and a difference of a maximum thickness (Y) and the minimum thickness (X) is at least 2 mm.

Description

TECHNICAL FIELD[0001]The present invention relates to a composite container for holding a powdered material or a liquid material having a flow property such as a cosmetic solution, a chemical, and a beverage. More specifically, the present invention relates to a composite container of which an outside layer is made of a resin.BACKGROUND ART[0002]As a container for holding a liquid material such as a cosmetic solution, a chemical, and a beverage, a container with a cap having an excellent corrosion resistance and a satisfactory airtight property has been widely used. The container is made of a glass in general. In some cases however, a container made of a synthetic resin can also be used to obtain similar effects.[0003]The glass container has a dignity sense and a high quality sense, and is transparent whereby a condition inside the container is visible with the naked eye. Consequently, the glass container can be preferably used as a container of a cosmetic solution in particular. Ho...

Benefits of technology

[0018]For the present invention, by making a thickness of a highly transparent resin sheathing body (b) that has been integrated with a resin hollow molding body (a) to be a prescribed thickness, a shape and a profile of the resin hollow molding body (a) can be discriminated with clarity in the case in which a visual contact is carried out to the inside resin hollow molding body via the outside transparent resin sheathing body, whereby a design property can be improved. Moreover, a complicated shape can be adopted since a core part is made of a resin, a satisfactory decorating property can be displayed. Furthermore, a design property can be displayed to a satisfactory extent even by a combination of the two shapes, and the composite container is hardly damaged.

Problems solved by technology

However in some cases, the glass container may be easily damaged by a shock during a carrying operation or by a drop in use.

In many cases, the glass container has a simple shape, thereby being lack in a poor decorative property disadvantageously.

On the other hand, a container made of a synthetic resin is lack in a dignity sense and it is hard to project a high quality sense.

Consequently, a use application of the metal container is restricted.
