Description

  The present invention relates to a double container.

2. Description of the Related Art Conventionally, as a double container, for example, a configuration including an inner container that stores contents and a case body that stores the inner container as shown in Patent Document 1 below is known.
By the way, in recent years, from the viewpoint of environmental protection, it has been widely desired to adopt a double container that can be used only by replacing the inner container and, for example, solid products such as paper products and granular materials, and powders. It has been studied to store contents such as a body, a gel-like material, and a liquid in an inner container.

Japanese Patent Laid-Open No. 10-258875

  However, in the conventional double container, when contents such as solids and powders are accommodated in the inner container, the contents are inserted by inserting a finger or a jar from the mouth of the inner container when using the contents. As the remaining amount of the contents in the inner container decreases, the distance from the mouth portion to the contents becomes longer, which may make it difficult to remove the contents.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a double container that can prevent the contents from being difficult to be taken out even if the remaining amount of the contents is reduced. That is.

In order to solve the above problems, the present invention proposes the following means.
A double container according to the present invention is a double container comprising an inner container in which contents are stored and a case body for storing the inner container, the inner container having a bottomed cylindrical container. And a lid attached to the upper end opening of the container, wherein the container is formed so as to be capable of being reduced in the up-down direction, and a content outlet is formed in the lid, and the case The body includes an upper member that surrounds the upper end portion of the inner container and a lower member that surrounds the lower end portion of the inner container, and these two members are connected to be relatively movable in the vertical direction. It is characterized by.

In the present invention, when the contents are used, for example, with the double container placed on a desk or the like, it is possible to easily take out the contents in the container by inserting a finger or a bag from the outlet.
When the remaining amount of contents in the container is reduced, the container is contracted and deformed in the vertical direction, and the upper member and the lower member are relatively moved in the vertical direction. Thereby, the depth of a container becomes shallow and an extraction port and the bottom part of a container will approach. Therefore, even if the remaining amount of the contents in the container is reduced, it is possible to suppress the distance from the outlet to the contents and to prevent the contents from being difficult to be removed from the outlet. can do.

  One of the upper member and the lower member is formed with a guide body having a guide hole extending in the vertical direction, and the other is extended in the vertical direction in the guide hole in the vertical direction. A guided body fitted so as to be slidable may be formed.

  In this case, since the guided body is fitted in the guide hole so as to be slidable in the vertical direction, the relative movement in the vertical direction of the upper member and the lower member can be stabilized.

  Further, a pair of the guide body and the guided body may be provided so as to sandwich the inner container therebetween.

  In this case, since a pair of the guide body and the guided body are provided so as to sandwich the inner container therebetween, the relative movement in the vertical direction of the upper member and the lower member can be further stabilized.

A through-opening that opens in the guide hole is formed, and a second engaging portion that engages with the first engaging portion from below is provided in one of an upper end portion and a lower end portion in the through-opening. Positioning means formed with a pushing portion that can be pushed into the guide hole is disposed on the other side, and an intermediate portion in the vertical direction of the positioning means is formed on the inner peripheral surface of the through opening. The case body may be rotatably connected around a hinge axis extending in the circumferential direction of the case body.

In this case, since the second engaging portion is engaged with the first engaging portion from below, the relative approaching movement of the upper member and the lower member is restricted.
On the other hand, when the pushing portion is pushed into the guide hole, the positioning means rotates around the hinge axis, the second engaging portion moves toward the outside of the guide hole, and is detached from the first engaging portion. Thereby, since the restriction | limiting of the relative approach movement of an upper member and a lower member is cancelled | released, both members can be moved relatively close to an up-down direction. Thereafter, the pushing of the pushing portion is released, and the positioning means is restored and moved around the hinge axis, so that the second engaging portion moves toward the guide hole and is engaged before the approaching movement described above. Engage with another first engaging portion located above one engaging portion. Thereby, the relative approaching movement of the upper member and the lower member is restricted again.

  The upper member may be detachably mounted with a holding member that holds the lid while covering the lid from above.

  In this case, since the holding member that holds the lid is detachably attached to the upper member, it is possible to suppress the inner container from rattling against the case body. Furthermore, since the holding member covers the lid from above, it is possible to prevent the inner container from being accidentally pulled out from the case body.
