Claims (1)

[Scope of Claim for Utility Model Registration] (1) A truncated end with a truncated conical surface that narrows toward the back of the container is located deep within the inner periphery of the mouth of the cap screw member provided on the opening side of the container. An elastic squeezing piece having a central hole is attached, an annular convex portion is formed on the inner periphery of the opening on the inlet side from the base of the squeezing piece, and the coating is attached inside a cap part that is screwed into the opening screw member. The shank of the shaft has a substantially uniform outer diameter and is slidably inserted into the central hole of the elastic squeezing piece, and a packing cylinder having an inner diameter approximately equal to the outside diameter of the shank is attached to the base of the application shaft. A bulge having a diameter larger than that of the cylindrical portion and an elastic scraping protrusion protruding from the outer periphery thereof are provided at the tip of the packing cylindrical portion, and the truncated end of the scrubbing piece is provided at the tip of the bulging portion. A conical surface at the tip of the gasket is formed with a smaller inclination angle than the conical surface, and when the cap portion is screwed into the container portion, the bulging portion of the gasket and the elastic scraping protrusion touch the annular convex portion on the inner periphery of the mouth portion. The conical tip end of the seal is pressed against the truncated conical surface of the squeezer piece to push the remaining cosmetics back to the back of the elastic squeezer piece. A liquid cosmetic container that prevents shaft stains. (2) At the back of the inner periphery of the mouth of the cap screw member provided on the opening side of the container, there is an elastic squeezer having a truncated conical surface that narrows toward the back of the container, and whose truncated end serves as a central hole. annular protrusions are intermittently formed on the inner periphery of the opening on the inlet side from the base of the squeezing piece, and the shaft part of the applicator shaft is installed in the cap part that is screwed into the opening screw member. A cylindrical portion of a packing having a substantially uniform outer diameter that is slidably inserted into the central hole of the elastic ironing piece, and having an inner diameter substantially equal to the outer diameter of the shaft portion is fitted to the base of the application shaft. , a bulge having a larger diameter than the cylindrical portion and an elastic scraping protrusion protruding from the outer periphery thereof are provided at the tip of the packing cylindrical portion;
A gasket tip conical surface having a smaller inclination angle than the truncated conical surface of the scrubbing piece is formed at the tip of the bulging portion, and the bulging portion and an elastic scraping protrusion are formed on the shaft portion of the application shaft. When trying to get over the annular convex part, an air path is formed at a position that coincides with the truncated part of the elastic squeezing piece, and when trying to screw the cap part into the container part, the packing bulges out. When the portion and the elastic scraping protrusion try to get over the intermittent annular protrusion on the inner periphery of the mouth, an air passage that communicates with the air path and the vicinity of the intermittent annular protrusion is formed, and the bulge crosses over the intermittent annular protrusion. When the cosmetic part completely crosses over and is held deep therein, the conical surface at the tip of the seal comes into pressure contact with the truncated conical surface of the elastic squeezing piece and pushes the remaining cosmetics back beyond the elastic squeezing piece. A liquid cosmetic container that prevents shaft stains.
