  • Publication number: 20230363514
    Abstract: A cosmetic container package includes: a stick-shaped cosmetic material container that accommodates a stick-shaped cosmetic material inside and allows the stick-shaped cosmetic material to come out from an opening provided at a tip end; and a packaging body that sandwiches and packages the stick-shaped cosmetic material container with a film. The packaging body includes a welding portion that seals the stick-shaped cosmetic material container up to the vicinity of an outer periphery by welding the film together. The welding portion further includes a tip end side annular portion that annularly adheres to the outer periphery of the stick-shaped cosmetic material container in the vicinity of the opening.

  • Patent number: 11647823
    Abstract: A cosmetic material feeding container includes a sleeve that is configured to accommodate a cosmetic material, a barrel that is engaged with the sleeve, a moving body that is accommodated in the sleeve and has a male screw on an outer periphery of the moving body, a screw in which a female screw to be screwed with the male screw is formed on an inner periphery of the screw, and a tail plug that is engaged with the barrel, relatively rotatable with the barrel, and is engaged with the screw. An enlarged diameter portion of the moving body is configured to contact with a spring portion of the screw from an inner side when the enlarged diameter portion comes to a position at which inward bending of the spring portion in a radial direction is restricted.

  • Patent number: 11160350
    Abstract: A cosmetic material container includes a container body, a leading cylinder, and a cap forming a hole to receive the leading cylinder. A leading cylinder front portion forms an opening and is tapered toward the opening. A cross section of the leading cylinder front portion forms a flattened shape extending in a first major axis and a first minor axis. A closed-ended closing portion inside the cap covers the opening of the leading cylinder, and has an inner surface to contact the leading cylinder front portion. A cross section of the hole of the cap forms a flattened shape extending in a second major axis and a second minor axis. The hole includes a guide surface so that the first major axis of the leading cylinder front portion coincides with the second major axis of the hole of the cap when the leading cylinder is inserted into the hole.

  • Patent number: 10299564
    Abstract: The rod-shaped cosmetic material feeding container includes a female screw portion provided with a female screw for screw engagement with a male screw of a rod-shaped cosmetic material support, a coil spring that restrains the female screw portion from moving forward in an axial direction, and a resin spring that restrains the female screw portion from moving rearward in the axial direction. An impact in the axial direction that acts on the female screw portion is absorbed by one spring, and an impact due to a restoring force at the time of restoration of one spring is absorbed by the other spring, whereby a rod-shaped cosmetic material supported by the rod-shaped cosmetic material support put in screw engagement with the female screw portion is sufficiently protected.

  • Patent number: 9775422
    Abstract: A rod-shaped cosmetic material feeding container includes a tubular-shaped container with a front part and a rear part, a movable body with a male thread at an outer peripheral part, and supporting a rod-shaped cosmetic material at a distal end, and a female threaded member with a female thread at an inner peripheral part. First and second elastic bodies each accumulate resilient force and have different spring constants. The male thread and the female thread constitute a threaded engagement mechanism that, by relative rotation between the front part and the rear part, advances and retracts the movable body and causes the rod-shaped cosmetic material to appear and disappear from an opening of the container. The first elastic body is sandwiched between the rear part and the female threaded member and the second elastic body is sandwiched between the front part and the female threaded member.

  • Patent number: 9603435
    Abstract: At a distal end of a pipe member 4, a plurality of projections 4n are disposed circumferentially. The projection 4n extends frontward in an axial direction. At a tip end of a leading tube 3, a groove forming section G is disposed. The groove forming section G includes a plurality of grooves 3n circumferentially in an inner peripheral surface. The grooves 3n extend in the axial direction. The projection 4n of the pipe member 4 enters the groove 3n. At the leading tube 3, an inner diameter of a convex part 3p between the grooves 3n and 3n circumferentially arranged and an inner diameter of a pipe part that houses the projection 4n of the pipe member 4 and the stick-like material rearward with respect to this projection 4n of the pipe member are identical size.

  • Patent number: 9521893
    Abstract: A liquid cosmetic container wherein the operation portion is provided on side surface of the container body 1. When the operation portion is pressed from the outside, the valve body 5 seating on the valve seat portion 6a is moved in the axial direction by the valve pressing portion 6h and seats away from the valve seat portion 6a, so that the flow path, in which the liquid cosmetic flows, is opened and then, the liquid cosmetic is supplied to the application body 4. Thus, it is not necessary to push the application body into the container 1. Further, the opening/closing of the flow path are performed by moving the valve body 5 in the axial direction by pressing the operation portions from the outside, so that the diameter of the container body 1 can be reduced, comparing with the conventional container.

  • Patent number: 9510660
    Abstract: A coil spring for cosmetic material is a one spring where a first spring part and a second spring part whose winding wire diameters and spring constants differ from one another are continuously and integrally formed via a stepped part. Accordingly, the use of the first spring part and the second spring part allows, for example, achieving absorbing an impact in both directions of an axial direction and sequential movements of the components constituting the cosmetic container, thus allowing providing wide variety of functions with the one spring. For example, the use of the stepped part also allows locking the component constituting the cosmetic container.

  • Patent number: 9307823
    Abstract: To provide a rod-shaped cosmetic material feeding container that can sufficiently protect a rod-shaped cosmetic material from impact acting in an axial direction. The rod-shaped cosmetic material feeding container includes a female thread part with a female thread. The female thread is screwed with a male thread of a movable body. One elastic body absorbs impact acting on the female thread part in an axial direction due to, for example, a drop. The other elastic body absorbs impact due to restoring force generated when the elastic body restores. Thus, a rod-shaped cosmetic material supported by the movable body threadably mounted on the female thread part can be sufficiently protected.
