Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container with a replacement bottle.
[0002]
[Prior art]
From the viewpoint of reducing waste or from the viewpoint of resource utilization, some of the containers that have been used up in the past can be reused by refilling them into the containers after they have been used up. In this case, only the container having a simple structure in which the refill, that is, the replenishment, is stored is discarded.
[0003]
[Problems to be solved by the invention]
The container for storing the replenishment storage is generally formed of a thin synthetic resin container. It is desirable to make the container as thin as possible because it is a one-time use. However, if the container is thinned to a flexible bag shape, the container body is opened and the contents stored in the container are used over a long period of time. Therefore, when transferring to the original container body, the bag-like container body due to thinning is difficult to hold because of its low rigidity, and therefore, the replenishment operation of the stored items becomes difficult.
[0004]
The present invention does not transfer the stored item, but uses the container body for storing the replenished stored item in a durable bottle until the stored item is used up. The empty container body is provided so that it can be used by replacing it with a new container body for storing the replenishment storage items.
