Abstract

A slide type lipstick case prevents a cosmetic stick from sliding down when using the lipstick case, while maintaining soft sensitivity when operating the lipstick case, by: forming a button and a button guide slit into which the button is inserted on the outer peripheral surface of an outer case; connecting a slide member for moving the cosmetic stick upwards and downwards, to a rib of the button and the lower end of a cosmetic stick holder; forming control protrusions on the upper and lower side of the button guide slit; and forming friction protrusions, at the rib of the button, for interfering the upward and downward movements of the button by fractionizing button guide slit.

First claim

The invention claimed is:

1. A slide-type lipstick container comprising:
an external case ( 10 ) formed in an outer circumferential surface thereof with a button guide slit ( 11 );
an internal case ( 20 ) mounted in the external case ( 10 ) and formed in an inside thereof with a guide groove ( 23 );
a slide member ( 30 ) mounted in the guide groove ( 23 ) of the internal case ( 20 ) and formed at both ends thereof with a rib mounting groove ( 32 ) and a coupling protrusion ( 33 );
a button ( 40 ) coupled to the rib Mounting groove ( 32 ) of the slide member ( 30 ) and having ribs ( 41 );
a lipstick holder ( 50 ) coupled to the coupling protrusion ( 33 ) of the slide member ( 30 );
a guide tube ( 60 ) coupled to the external case ( 10 ),
wherein the slide member ( 30 ) includes an elastic sheet ( 31 ) having a thin plate shape to be vertically movable along the guide groove ( 23 ) of the internal case ( 20 ), and the ribs ( 41 ) of the button ( 40 ) are paired, an elastic space ( 43 ) is formed between, the paired ribs ( 41 ), and friction protrusions ( 42 ) are formed on lateral sides of the ribs ( 41 ); and
a stud ( 12 ) formed in the button guide slit ( 11 ) of the external case ( 10 ).

2. The slide-type lipstick container of claim 1 , wherein the internal case ( 20 ) has an elastic sheet mounting space ( 24 ) defined by a lateral side of the internal case ( 20 ).
