Abstract

A lipstick case having a structure wherein a lipstick is exposed outwards when lowering an ascending and descending member which encases the lipstick as rotating a rotation body to one side direction, whereas the lipstick is hidden by the ascending and descending member when the rotation body to the other side direction is rotated and thereby the ascending and descending member ascends. Therefore, it is possible to fundamentally prevent problems in use, e.g. a breakage of lipstick caused by closing a cover part in a state of the lipstick being ascended.

First claim

What is claimed is:

1. A lipstick case comprising:
a lipstick holder loaded with a lipstick;
a rotation body including a fixing body disposed at a lower portion of the lipstick holder and protrusively formed from a center portion of a lower end thereof to an upper direction so as to fix the lipstick holder, and a first screw thread formed at an inner circumferential surface thereof;
an ascending and descending member including a second screw thread coupled in a screw coupling with the first screw thread at an outer circumferential surface thereof so as to be rotated by a rotation of the rotation body, wherein the ascending and descending member receives the lipstick when ascending, and exposes the lipstick to the outside when descending;
an ascending and descending guide member rotatably coupled with the rotation body, and comprising a rotation preventing means which prevents the ascending and descending member from being rotated when the rotation body rotates, and guides a vertical movement of the ascending and descending member; and
a cover part encasing the lipstick and detachably coupled to the ascending and descending guide member.

2. The lipstick case of claim 1 ,
wherein the ascending and descending member comprises: a guide tube wherein the fixing body is inserted and the second screw thread is formed at an outer circumferential surface thereof; and a lipstick receiving tube which is extended from the guide tube to an upper portion thereof and receives the lipstick.

3. The lipstick case of claim 2 ,
wherein the rotation preventing means comprising a penetrating hole equipped at a lower end of the ascending and descending guide member such that the ascending and descending member can be penetrated to the penetrating hole and thereby ascended and descended, wherein the penetrating hole has an oval shape so as to prevent a rotation of the guide tube, and the guide tube has a shape which corresponds to the shape of the penetrating hole.

4. The lipstick case of claim 2 ,
wherein the rotation preventing means comprises a rotation guiding part which is disposed at an upper portion of the ascending and descending guide member and has a square shape with all corners rounded so as to prevent a rotation of the lipstick receiving tube, wherein the lipstick receiving tube is configured to have a shape which corresponds to the shape of the rotation guiding part.

5. The lipstick case of claim 1 ,
wherein at the ascending and descending member is provided a limiting protrusion which meets a lower end of the lipstick holder or a protrusion of the ascending and descending guide member and limits an ascent of the ascending and descending member during an ascending process.
