Description

[Detailed description of the invention] Industrial application field This invention relates to a dispensing container for stick-shaped cosmetics such as lipstick.

BACKGROUND OF THE INVENTION Various types of containers for dispensing bar-shaped cosmetics have been known in the past, but these containers do not have a structure in which the interior of the bar-shaped cosmetic storage chamber is sealed when the bar-shaped cosmetics are stored and capped.

Problems that the invention aims to solve As mentioned above, since the bar-shaped cosmetic storage chamber is not sealed, if it is left in a store for a relatively long time, or if a consumer continues to use it for a long time, Initially, the freshness of bar-shaped cosmetics was lost due to the scent being lost or drying out.

This proposal is primarily aimed at eliminating such drawbacks.

Means for Solving the Problems The present invention includes an inner cylinder 1, an outer cylinder 4, a sliding cylinder 7, a bar-shaped cosmetic with a saucer 11, and a cap 16.

The inner cylinder 1 has a plurality of vertical grooves 3 vertically arranged in the lower half of the first inner cylinder 2 having an open upper end surface, usually at left and right opposing positions.

The second cylinder 5 of the outer cylinder 4 is rotatably fitted to the outer surface of the lower half cylinder part of the inner cylinder. A threaded groove 6 is bored in the inner wall surface of the second cylinder.

The sliding cylinder 7 has a third cylinder 8 fitted into the inner cylinder 1 so as to be able to move up and down, and a plurality of engagement pins are inserted from the outer surface of the lower part of the third cylinder through the respective vertical grooves 6. 9 is projected, and the tip of the engagement pin is engaged in the threaded groove.

The bar-shaped cosmetic product 11 with a saucer has a second fitting part 12 tightly fitted into a first fitting part 10 formed at the upper end of the sliding tube, and a third fitting part 12 which is made to hang down from the second fitting part. Inside the fitting cylinder part 13, the base end of the bar-shaped cosmetic 14 is fixed, and a sealing piece 15 provided around the outer surface of the third fitting cylinder part is airtightly attached to the inner surface of the upper half of the inner cylinder 1. It is in contact.

The upper half of the inner cylinder of the cap 16 is inserted into the cap 16, and the lower end of a peripheral wall 18 hanging from the periphery of the top wall 17 is fitted onto the outer surface of the outer cylinder 4.

A ventilation blocking wall 19 is installed horizontally between the lower end of the rod-shaped cosmetic and the inner surface of the sliding cylinder, and a sealing part 20 that airtightly closes the gap between the upper outer surface of the inner cylinder 1 and the inner surface of the cap circumferential wall is installed in the inner cylinder area. Alternatively, it may be attached to one of the surrounding walls of the cap.

Function When the cap is closed as shown in the figure, the ventilation blocking wall 19
With the seal part 20 and the sealing piece 15,
The bar-shaped cosmetic product 14 is shielded from the outside air.

When the cap 16 is removed from the illustrated state, the upper part of the inner cylinder 1 is held, and the outer cylinder 4 is turned in the forward direction, the tip of the engagement pin 9 is engaged in the threaded groove 6 on the inner wall surface of the outer cylinder. In addition, since the engagement pin is inserted into the vertical groove of the inner cylinder, it can move up and down with respect to the inner cylinder, so the engagement pin rises along the threaded groove, and therefore The bar-shaped cosmetic product 11 with a saucer fitted to the upper end of the sliding cylinder is fed out from above the inner cylinder, and when the outer cylinder 4 is turned in the opposite direction, the bar-shaped cosmetic product with a saucer is fed into the inner cylinder again. That will happen.
When the cap 16 is fitted, the lower end of the circumferential wall of the cap is fitted into the outer cylinder 4, making the above-mentioned feeding operation impossible.

Embodiment The ventilation blocking wall 19 may be formed of a top wall attached to the upper end of the small diameter part with the upper end of the sliding tube 7 as a small diameter part as shown in the figure, or a bottom wall may be provided on the inner surface of the saucer and the bottom It may also be formed by a wall. Furthermore, it is also possible to form a separate member on the inner surface of the upper part of the sliding tube or the inner surface of the cylindrical portion of the saucer.

As shown in the figure, the seal portion 20 is preferably formed by fitting a small cap-shaped member 21 into the inner part of the cap and attaching it to the inner surface of the peripheral wall 22 thereof.

Effect: With the cap closed, the bar-shaped cosmetic product 14 is shielded from the outside air, so the fragrance or moisture inherent in the bar-shaped cosmetic product does not dissipate, and the original state of the bar-shaped cosmetic product can be maintained for a long time. can.
