[Detailed description of the invention] [Purpose of the invention] Industrial application field This invention relates to an additive mixing device in a hand pump used for cosmetics, shampoos, rinses, etc.

BACKGROUND ART Conventionally, there have been containers equipped with hand pumps used to store liquid or cream cosmetics, shampoos, conditioners, and the like.

This container is equipped with a hand pump that can be detachably attached to the mouth of the container body that stores the above-mentioned contents. It is something that ejects something from the outlet of its head.

Problems to be Solved by the Invention The present invention is to attach an additive mixing device to the above-mentioned hand pump to mix the additive into the discharged material.

[Structure of the invention] Means for solving the problem The present invention is a hand pump that ejects the contained material from the discharge port by pushing down the head with the discharge port, and is equipped with an additive container on the top surface of the head in a detachable manner. In addition, an additive inlet passage is formed in the head to open the additive container to the discharge passage in the head, and the additive inlet passage allows the additive from the additive container to be connected to the discharge passage in the head. A check valve is provided to unilaterally supply the additive to the head, and the additive contained in the additive container is supplied under pressure by a bellows, cylinder type pump, etc. It is characterized by taking measures.

Function: With the above structure, when the required additive is stored in the additive container, the hand pump is attached to the mouth of the container containing the contents, and the head is pushed down. The contents in the container body are ejected from the discharge port of the head, and at this time, the additives in the additive container are discharged through the check valve by operating the pressurized supply means such as the bellows or cylinder pump of the additive container. When the additive is pressurized and supplied to the discharge passage in the head through the discharge passage, the additive is mixed into the discharge from the container body flowing through the discharge passage. Note that since there is a check valve, the discharged material from the container body will not flow into the additive container.
