Mixed structure packaging container with contents

[Abstract] The present invention relates to a packaging container having a mixed structure of contents. Its structure is that it has a container body, a discharge pump, and a moving bottom. With the discharge of the contents caused by the pump operation, the bottom rises by an amount equivalent to the discharged volume, and air is not sucked into the container body. In the pump container having such a configuration, while the main container and the sub-tank separated by the separating device are provided, the separating device can operate to communicate the main container and the sub-tank to mix the contents of both.
[Sovereign Items] 1. A mixed-structured packaging container with contents, having a container body, a discharge pump, and a moving bottom, with the discharge of the contents resulting from the pump operation, the bottom-up movement and the discharged volume An equivalent volume, and a pump container that does not form an air layer in the container body, is characterized by having a main container, a sub container separated from the main container by a separating apparatus, and the separating apparatus also serves as a communication master. The communication device for the container and the sub-tank can change the separation state and the communication state, and in the communication state, the content in the sub-tank can be introduced into the main vessel to mix the contents of both.
