Description

  The present invention relates to a refill container comprising a container body having a mouth connected to a filling space for contents and a spout provided at the mouth of the container body.

  Containers containing shampoos, rinses, detergents, deodorizers, cosmetics, etc. are distributed in the market with a discharge device such as a pump attached to the mouth of the container in order to allow the appropriate amount of contents to be removed. After the contents are used up, resources can be effectively saved by transferring new contents from the refill containers that are sold separately and reusing the original containers (containers that are refilled). Utilization is planned.

  By the way, a refill container is often a low-rigidity container such as a pouch-type container or a thin-walled blow-molded container, but such a container is easily deformed and it is difficult to refill the contents. There was also a risk of the contents adhering to the fingers. In order to solve this problem, Patent Document 1 discloses that a base is formed on a base of a container body, and a base that is engaged with and held by the mouth, and a base that is pivotably held by the base and is raised. A turret-type refill container is disclosed, which is provided with an extraction stopper that is aligned with the opened opening and allows the contents to be extracted. According to such a refill container, the contents in the refill container can be transferred simply by hooking the barrel of the spout tap on the mouth of the container to be refilled to cause the cylinder. .
