Title:
CHECK VALVE STRUCTURE, NOZZLE MEMBER USING SAME, AND SQUEEZE CONTAINER
Document Type and Number:
WIPO Patent Application WO/2017/086255
Kind Code:
A1
Abstract:
Provided are: a check valve structure that prevents the back-flow of fluid and that also prevents fluid from being discharged by unintended pressure in the correct direction; and a squeeze container using said check valve structure. This squeeze container 10 comprises a container 11, and a nozzle member 12 attached to an opening 11a of the container 11. The nozzle member 12 is provided with a check valve structure 15 that is closed in a non-loaded state, and that inhibits the flow of fluid from downstream and permits the flow of fluid from upstream. The check valve structure 15 opens as a result of two-stage elastic deformation of an elastic valve body 18 against a pressure of the fluid from upstream (the container 11).
