Lipstick case

Abstract

Proposed is a lipstick case comprising: a first case having a pillar shape and having a lipstick accommodated therein; a second case having a pillar shape and having the first case accommodated therein; and a third case having a pillar shape and having the second case accommodated therein. A first protrusion outwardly protruding from the first case moves while being accommodated in a coupling slit formed to be long on one side of the second case, and thus the first case can move inside the second case. The third case can be coupled to the first protrusion.

1 . A lipstick case comprising:
 a first case having a first body having a pillar shape to accommodate a lipstick therein, a first coupling portion formed on one side of the first body, and a second coupling portion formed spaced apart from the first coupling portion on the other side of the first body;   a second case having a second body having a pillar shape to accommodate the first body therein, a coupling slit formed on one side of the second body to accommodate a portion of the first coupling portion therein, and second grooves formed on the inner peripheral surface of the second body in such a manner as to be coupled to the second coupling portion; and   a third case having a third body having a pillar shape to accommodate the second case therein and a third hook formed on the inner end periphery of the third body,   wherein the coupling slit is extended long in a longitudinal direction of the second body, and the first coupling portion comprises: a bridge formed on one side of the first body; and a first protrusion located in the bridge, protruding outward from the first body, accommodated in the coupling slit in such a manner as to be movable in the longitudinal direction, and coupled to the third hook.   
     
     
         2 . The lipstick case according to  claim 1 , wherein the bridge provides elasticity to the first protrusion in inside and outside directions of the first body. 
     
     
         3 . The lipstick case according to  claim 2 , wherein the bridge comprises:
 a first bridge extended from the first body in a longitudinal direction of the first body;   a second bridge extended from the first body in the longitudinal direction of the first body in such a manner as to be spaced apart from the first bridge; and   a third bridge connecting the first bridge to the second bridge, extended from the first bridge in a transverse direction of the first body in such a manner as to be connected to the second bridge, and coupled to the first protrusion.   
     
     
         4 . The lipstick case according to  claim 2 , wherein the coupling slit comprises:
 a sliding slit extended long in the longitudinal direction of the second body; and   a seating hole communicating with the end portion of the sliding slit and having the corresponding shape to the first protrusion, and the width of the coupling slit becomes reduced and then enlarged toward the seating hole from the sliding slit.   
     
     
         5 . The lipstick case according to  claim 4 , wherein the second case comprises a locking portion formed between the sliding slit and the seating hole in such a manner as to protrude from the second body toward the interior of the coupling slit. 
     
     
         6 . The lipstick case according to  claim 2 , wherein the second grooves comprise a plurality of dimples concavely formed toward the interior of the second body in the longitudinal direction of the second body, and the second coupling portion comprises: an arm formed on the other side of the first body; and a second protrusion located on the arm, protruding outward from the first body and coupled or separated to or from one of the plurality of dimples while the first protrusion is moving in the coupling slit. 
     
     
         7 . The lipstick case according to  claim 6 , wherein the arm provides elasticity to the second protrusion in the inside and outside directions of the first body. 
     
     
         8 . The lipstick case according to  claim 2 , wherein the third hook comprises:
 a first slant surface connected to one end periphery of the third body and having a first angle with respect to a longitudinal direction of the third body; and   a second slant surface extended to the other end periphery of the third body and having a second angle with respect to the longitudinal direction of the third body.   
     
     
         9 . The lipstick case according to  claim 8 , wherein the first slant surface faces the outside of the third body, and the second slant surface faces the inside of the third body. 
     
     
         10 . The lipstick case according to  claim 9 , wherein the second angle is larger than the first angle. 
     
     
         11 . The lipstick case according to  claim 8 , wherein the third case comprises a third groove extended from the second slant surface toward the other end periphery of the third body in such a manner as to be concave toward the interior of the third case. 
     
     
         12 . The lipstick case according to  claim 11 , wherein the third hook is convex toward the interior of the third case. 
     
     
         13 . The lipstick case according to  claim 1 , wherein the first body comprises: a first pillar having a hollow portion open on both ends thereof; a partition plate located in the hollow portion of the first pillar, and the first pillar is divided into upper and lower portions with respect to the partition plate, the upper portion of the first pillar and the partition plate being adapted to accommodate the lipstick therein. 
     
     
         14 . The lipstick case according to  claim 13 , wherein the first coupling portion and the second coupling portion are located on the lower portion of the first pillar.
