A cosmetic container () has a cap () with a first cap portion (). An inner cylinder () is fit internally to an upper part of the first cap portion, and a return spring () biases the inner cylinder up. A second cap portion () is fit rotatably on the first cap portion. The first cap portion has a temporary holding hole () in which a guide protrusion () of the inner cylinder is held temporarily against the biasing force of the return spring so that an upper end of the inner cylinder is lower than an upper end portion of the first cap portion when the guide protrusion is held temporarily in the temporary holding hole. Thus, the upper end of the first cap portion can deform to bend inward without being obstructed by the inner cylinder when the second cap portion is fit on the first cap portion.

Rod-shaped cosmetic container

A tubular cosmetic container has a cap () fit outside a container body (), a cap body (), an inner cap () fit inside the cap (), and a to-be-covered portion. The inner cap () is formed with a first protrusion () located at a halfway covering posture during the course of covering the container body () from the halfway covering posture through an immediately preceding covering posture to a fully covering posture and applying a first slide resistance by being pressed into sliding contact with the container body (), and a second protrusion () located at the immediately preceding covering posture of covering the container body () and applying a second slide resistance larger than the first slide resistance by being pressed into sliding contact with the upper end of the container body.

Cylindrical cosmetic container

A cosmetic container (X) has a cap () that is fit externally onto a container body (), in which a cosmetic is stored, to fully cover a to-be-covered portion of the container body (). First and second magnets (and) are disposed respectively in the cap () and the container body () so as to oppose each other in the completely covered condition and so that the cap () fully covers the container body () by the mutual magnetic attachment of the magnets (). Each magnet () is formed into a ring in a circumferential direction and having a plurality of magnetic poles disposed alternately in the circumferential direction.

Cosmetic container

A thrust-out type container for a rod-like article generally comprises a driving cylinder extending in a vertical direction, a cylindrical holder extending in the vertical direction inside the driving cylinder, and a guide cylinder adapted to restrict a movement of the holder so that the holder can not be non-rotatable with respect to the driving cylinder but movable in the vertical direction. The driving cylinder includes an outer cylinder formed on its inner peripheral surface with a first groove and an inner cylinder lying inside the outer cylinder and slidably engaged with the first groove so as to be movable in the vertical direction and formed on its inner peripheral surface with a second groove. An upper portion of the holder defined as a cup is configured so that the rod-like article can be attached thereto and a lower portion of the holder defined as a stem extending downward from the cup is adapted to be slidably engaged with the second groove of the inner cylinder.

Thrust-out type container for a rod-like article

A thrust-out type container for a rod-like article such as a lipstick basically comprising a body and a cap. The body has an axis C extending in a vertical direction and comprises, around the axis C and radially outward from the axis C, a movable member, an inner cylindrical tube, an outer cylindrical tube and a control tube in this order. An intermediate cylindrical tube is interposed between the outer cylindrical tube and the control tube. The intermediate cylindrical tube is fixed to the control tube and rotatable around the outer cylindrical tube. An outer peripheral surface of the intermediate cylindrical tube and an inner peripheral surface of the cap come in air-tight contact with each other. The intermediate cylindrical tube extends downward beyond respective lower ends of the inner and outer cylindrical tubes and has a bottom covering the respective lower ends of these tubes.

A cylindrical cosmetic container includes an inner tubular member (1) formed with axially extending slots (2); an outer tubular member (7) formed with a spiral groove (9) and rotatably fitted to an outer circumferential surface of the inner tubular member; and a movable cup member (11) for mounting thereon a cylindrical cosmetic (15) to be accommodated within the inner tubular member, and the movable cup member having projection pins (13) attached on an outer circumferential surface thereof and engaged with the spiral groove of the outer tubular member through the slots of the inner tubular member. The inner tubular member (1) is formed with a bridge portion (101) at a base end portion thereof; and the bridge portion is further formed with a projection portion (103) which is brought into elastic contact with the base end portion of the outer tubular member. Since the sliding frictional resistance between the inner and outer tubular members can be increased, both the tubular members are not rotated easily relative to each other, even when a force is applied to the movable cup member through the cylindrical cosmetic in the direction in which the cup member is pushed into the container, thus preventing the retractive phenomenon from occurring. Further, since the clearances between the movable cup member and the inner and outer tubular members can be increased, it is possible to eliminate the use of any lubricant.
