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.

A two-fluid discharge container, comprising:
- a container body including a body portion which has one end which is an opening portion and another end having a bottom lid;
- 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;
- and
- a valve assembly which closes the opening portion of the container body, the valve assembly having a passage which communicates the first storage portion and the second storage portion with the exterior,
- 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,
- wherein the first pressurizing portion is a first piston portion sliding within the first storage portion, and the second pressurizing portion is a second piston portion sliding within the second storage portion,
- wherein the first storage portion and the second storage portion are provided concentrically,
- wherein the first storage portion and the second storage portion are partitioned by the piston,
- wherein the container body has a first body portion, a second body portion whose inner diameter is greater than the inner diameter of the first body portion, and a step portion provided between those,
- wherein there is provided a sliding layer in the inner peripheral surface of the first body portion,
- wherein there is provided a communication passage which communicates the valve assembly and the second storage portion between the inner periphery surface of the first body portion and the outer periphery surface of the sliding layer, the communication passage constituting a passage to communicate the second storage portion with the exterior,
- wherein the piston is a convex body provided with a tubular main body portion sliding on the inner surface of the sliding layer, and a flange portion sliding on the inner surface of the second body portion, being provided in the outer periphery of the main body portion, and a tip of the main body portion constitutes a first piston portion and the flange portion constitutes a second piston portion,
- wherein the contents of the first storage portion and the second storage portion are simultaneously pressurized and discharged by the piston.
