Title:
CAP FOR DISCHARGE CONTAINER OF CONTENT
Document Type and Number:
Japanese Patent JP3676024
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the contents sticking to a slit valve due to liquid-dripping or the like on discharging it from penetrating to the outside, by providing a hermetically sealing ring on the upper wall of a cap body and keeping air-tight the inside of the slit valve holder of the cap when closing an opening/closing cover by the hermetically sealed ring provided in the cover.
SOLUTION: When an opening/closing cover B2 is opened and the orifice- forming wall 76 of the valve head 71 is exposed and the body wall of the container A is pressed, the valve head 71 is raised as the inner pressure increases. When the inner pressure reaches a certain value, the recessed part of the orifice- forming wall 76 rises and the surface gets flat. When the body wall of the container is further pressurized, a flap is opened and an orifice is formed and the contents are discharged. A hermetically sealing ring 30 having an expansion ring 29 at the outer periphery of the opening 28 is erected and a hermetically sealing ring 55 having an expansion ring 54 at the outside of the locking ring 53 is erected to keep air-tight the valve holder. And hence, even if the contents stick to the periphery of the slit valve owing to the liquid-dripping or the like on discharging the contents and the liquid does not flow to the outside.
