Description

  The present invention relates to a refill container, and is intended to efficiently refill the contents without causing leakage of the contents or dirtying hands or clothes.

  As containers for shampoos, rinses, detergents, deodorizers, cosmetics, etc., many products equipped with a discharge device such as a pump tend to be put on the market in order to make it possible to take out an appropriate amount of contents. After using up the contents, it is normal to transfer the new contents from a refill container that is commercially available and reuse the original container (hereinafter referred to as “continuous use container”). Thus, the resources are effectively used (for example, see Patent Document 1).

  By the way, the refill container is originally a pouch-type container or a thin-walled blow molded product such as a low-strength (low rigidity) container, and it is difficult to refill the contents. Although various proposals have been made so far, such as transferring the contents after connecting two containers via screws, the conventional refill containers take time to refill. The current situation is that improvement is required.
