The present invention relates to a lipstick case, and more particularly, to a lipstick case for preventing the lipstick from being pushed down in the case when applying the lipstick to the lips.

In general, a lipstick case is composed of a lipstick holder, an inner sleeve, an outer sleeve and a decorative sleeve. The lipstick holder for holding the lipstick is a sleeve having projections projecting radially on opposite opposing sides, and is fitted in the inner cylinder sleeve. The inner cylinder sleeve has slots extending in the longitudinal direction on opposite sides thereof, and protrudes from the lipstick holder through the slots. An outer cylinder sleeve is fitted to an outer surface of the inner cylinder sleeve, and a continuous spiral channel is formed on an inner wall of the outer sleeve. The projection of the lipstick holder is configured to penetrate the slot of the inner sleeve and fit into the spiral channel of the outer sleeve to move along the entire length of the spiral channel. When the outer sleeve is rotated with respect to the inner sleeve, the projection of the lipstick holder moves up and down in the slot of the inner sleeve as it moves the entire length of the spiral channel of the outer sleeve. The outermost decorative sleeve is provided for aesthetic purposes. In use, the bottom of the inner sleeve sleeve protrudes past the bottom of the outer decorative sleeve. The user rotates the lipstick case with one hand, i.e. by holding the bottom of the inner sleeve with the middle and palms and rotating the outer sleeve in one direction with the thumb and forefinger, causing the lipstick holder, ie the lipstick, to come out of the case, thereby bringing the lipstick to the lips. After application, the outer sleeve is rotated in the opposite direction to the one direction to allow the lipstick to enter the case.

Rotating the upper sleeve 31 in one direction causes the projection 11 of the lipstick holder 10 to follow the inside of the spiral channel 33 of the outer sleeve 30 and open the slot 24 of the inner sleeve 20. It will move upwards, causing the lipstick to come out of the case.

In addition, the user rotates the outer sleeve 30 to bring the lipstick out of the use position, and then applies the lipstick to the lips.

Next, the user rotates the outer sleeve 30 in the opposite direction to the one direction so that the projection 11 of the lipstick holder 10 follows the inside of the spiral channel 33 of the outer sleeve 30 and the inner sleeve 20. Move downward along the slot 24 of the lip to allow the lipstick to enter the case.

Here, the convex part 32b of the outer cylinder sleeve 30 elastically abuts against the groove 22a of the inner cylinder sleeve 20 to impart rotational torque between the inner cylinder sleeve 20 and the outer cylinder sleeve 30. The end face reduction portion 32a allows the outer sleeve 30 to rotate smoothly with respect to the inner sleeve 20, and the lipstick holder 10 even when an axial force is applied downward to the lipstick when applying the lipstick to the lips. Elastic force to provide a rotational torque between the inner sleeve 20 and the outer sleeve 30 so that the projection 11 of the c) does not easily slide downward in the spiral channel 33 of the outer sleeve 30. It is desirable to set. That is, it is preferable to form the angle (alpha) which the string which connects two points on the outer peripheral surface of the outer cylinder sleeve 30 with respect to the center axis O of the outer cylinder sleeve 30 is 25 degrees-30 degrees.

On the other hand, the inner cylinder sleeve 20 and the outer cylinder sleeve 30 of the present invention is formed by a pair of upper and lower molds, the product of the upper and lower pair of molds is a burr (burr) at the portion where the upper mold and the lower mold are joined ) Will inevitably occur. In particular, a burr formed on opposite sides of the groove 22a of the inner cylinder sleeve 20 is caught when the convex portion 32b of the outer sleeve 30 rotates against the groove 22a of the inner sleeve 20. Act as.

Such burrs may be removed by cutting the burrs in the grooves 22a of the inner sleeve 20, as shown in FIG. 2B.
