Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a container. More specifically, the present invention relates to containers such as cosmetic containers, quasi-drug containers, and pharmaceutical containers.

[0002]

2. Description of the Related Art Conventionally, as a container containing a lotion, for example, there is a container in which a cap is detachably attached to an inner plug attached to an upper portion of a container body. Also,
In order to improve the beauty of the container, a shoulder part is attached to the shoulder of the container body. A glass bottle is usually used for the container body of the cosmetic container, but a synthetic resin such as polyethylene or polypropylene is used as a material of the shoulder parts.

In recent years, when discarding used containers, consumers are required to separate and dispose of resource refuse according to material as part of a recycling campaign. For this reason, in the manufacturer, in order to make it easier for consumers to separate and discard containers that have used up lotion, a recess is formed in the side surface of the resin shoulder part, and a tool such as a screwdriver or a coin is formed in the recess. And then lift it to separate the shoulder parts from the glass bottle.

[0004] However, for a consumer, the work of inserting a screwdriver into the recess of the shoulder part to separate the shoulder part from the glass bottle tends to be complicated, and there is a concern that the consumer may avoid sorting and discarding.

On the other hand, as a container for easily separating a container body and a shoulder member (cover) made of different materials, there is a container in which the container body and the shoulder cover are mounted by a rotation operation (Japanese Patent Laid-Open No. 10-16979, JP-A-11-49168
Reference). Such a container is easier to separate than a container that is separated using the tool or the like, but together with the shoulder cover, the cap is also screwed into the container body,
When the used container is discarded, two screw tightening release operations are required, and there is a problem that the separation operation is still troublesome.

On the other hand, there is provided a container in which a cap is detachably fitted to a shoulder member (shoulder part) and the shoulder member is pressed and fixed at the lower end of the outer periphery of the discharge tool screwed into the mouth of the bottle body. (See Japanese Patent Application Laid-Open No. 2000-109074). However, in such a container, when disposing of the used container, the shoulder member must be removed to the floor by mistake after removing the screw of the discharging device and removing the shoulder member with a finger or by turning the container upside down. For example, separation work may be troublesome.

[0007]

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a container capable of easily separating a used container into constituent parts of different materials.
