Abstract
Provided is a two fluid discharge container comprising: a container body; a piston partitioned by a first storage part and a second storage part, which are accommodated in the container body and are each to be filled with content, and a pressurized space to be filled with a pressurizing agent; and a valve mechanism that closes an opening in the container body, and has a passage through which the first storage part and the second storage part communicate. The first storage part and the second storage part are concentrically formed, and the contents of the first storage part and the second storage part are simultaneously pressurized by the piston so as to be discharged.
Claims21
A two-fluid discharge container, comprising;
- a container body, and
- a piston accommodated in the container body partitioning the container body into a compressing space equipped with a first storage portion in which a first content is filled and a second storage portion in which a second content is filled, and a pressurizing space in which a pressurizing means is housed,
- having a valve assembly which closes the opening portion of the container body, provided with a passage which communicates the first storage portion and the second storage portion with the exterior,
- a tube is provided the valve assembly,
- wherein the tube is inserted a center hole of the piston freely slidable vertically,
- wherein the tube and the center hole communicate the valve assembly with the storage portion.
- wherein the piston is provided with a first pressurizing portion which pressurizes the first storage portion,
- a second pressurizing portion which pressurizes the second storage portion, and
- a connecting portion which connects the first pressurizing portion and the second pressurizing portion, and
- wherein the contents of the first storage portion and the second storage portion are simultaneously pressurized and discharged by the piston.
