DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having an outer body attached to a shoulder portion or a bottom portion of a container body for decorating or adding a function to a bottle container or a jar container.
The present invention relates to a container with an exterior body, which is provided with an exterior body made of a different material from the container body so as to be removable from the container body.

[0002]

2. Description of the Related Art A container made of glass or synthetic resin material used as a daily necessity is provided with an exterior body made of a different material from the container body attached to a shoulder portion or a bottom portion of the container body to decorate the container or provide an impact. In addition, containers with an exterior body that make products unique and functional have been distributed.

[0003] The exterior body of the container with the exterior body is firmly fixed to the container body by being adhered, fitted or caulked so as not to be inadvertently detached during the distribution process or at the hands of the consumer. And cannot be easily separated from the container body.

[0004] In recent years, there have been social problems such as garbage disposal and resource reuse, and wastes have been separately collected by material. In order to respond to such social demands, it is necessary to make the container with the exterior body separable into the container body and the exterior body made of a different material by a consumer.

As containers corresponding to the above problems, for example,
2. Description of the Related Art A container with a dissimilar material member disclosed in JP-A-9-286438 is known.

In this conventional container, a space is formed between the container main body and an outer casing made of dissimilar material fitted undercut so that a plate member such as a coin or a flathead screwdriver can be inserted. When a consumer discards a container, a plate-like member such as a coin is inserted into this space, and the exterior body is separated using the principle of leverage.

[0007]

However, the above-mentioned conventional container in which the outer package is separable is difficult to determine from the appearance whether the outer package is separable and requires a jig for separation. The separation operation is troublesome, and even if the separation mechanism is provided, it is highly likely that the separation operation is not performed and is simply discarded.

The present invention has been made in view of the above problems, and when a consumer discards a container with an outer package, the outer package is easily separated from the container body without preparing a jig for separation. It is to make a container that can.

[0009]

According to another aspect of the present invention, there is provided a container provided with an exterior body, comprising a synthetic resin exterior body made of a different material from the container body on a shoulder portion or a bottom portion of the container body. The container body and the exterior body are engaged with each other by an undercut engagement mechanism by engagement of an engagement projection, and the exterior body is provided with a cutting portion that separates a peripheral wall of the container body. The exterior body can be removed by picking up the exterior body part on the side of the projection, opening the split part, bending the exterior body and releasing the engagement of the engagement projection. I did it.

It is preferable that a rotation prevention mechanism for reinforcing the rotation of the outer body is provided in the container body and the outer body to prevent the outer body from coming off due to bending of the outer body due to an unexpected impact.

Further, a breakable thin portion may be provided at the cut portion to reinforce the mounting strength of the exterior body.
