Cosmetics container having a sealed structure

Abstract

A cosmetics container having a sealed structure where an airtight state can be maintained inside the container by means of a simple structure, by using a configuration wherein the airtight state inside the container can be maintained by causing a sealing member to compress and spread out and to thereby attach hermetically to the inside of the body of the container and seal of the upper part of the body of the container as a result of downwards movement of a cap when one side of a lever member provided on the cap is pressed, and wherein the cap can be separated from the container by releasing the sealing member from the compression as a result of upwards movement of the cap when the other side of the lever member is pressed.

1 . A cosmetics container having a sealed structure, comprising:
 a container body that contains contents, the top of which container body is open; and   a cap that comprises:
 a cover part that is detachably engaged to the container body and covers top of the container body; 
 an elastic sealing member that is engaged to the cover part and of which lateral surface is widened in an outward direction by means of an operation of a lever member and comes into airtight contact with an inner circumferential surface of the container body thus providing a sealing function; 
 a lever member support body that is inserted in a bottom of the sealing member and of which central portion protrudes in an upward direction and that supports the lever member; 
 a fixing plate that is engaged to the lever member support body, at an inner portion of the sealing member, and that fixes the sealing member; and 
 a lever member that is engaged to the cover part and is connected to the lever member support body and rotates by a user's pressing and seals the interior of the container body using the sealing member. 
   
     
     
         2 . The container of  claim 1 , wherein in an inner portion of the container body is provided a mounting part that extends in an inward direction, covering an inner circumferential surface of the container body for the lever member support part to be mounted, and in an end portion of the mounting part is provided a content accommodation part that extends in a downward direction and contains contents. 
     
     
         3 . The container of  claim 1 , wherein in the top of an inner portion of the container body are provided a plurality of protrusions that are spaced apart at regular intervals, covering an inner circumferential surface, for thereby preventing developments of pressure in the container body. 
     
     
         4 . The container of  claim 1 , wherein in a central portion of the top of the cover part is provided a lever member engaging groove to which the lever member is engaged, and in the lever member engaging groove the lever member engaging groove includes a rotation limiting shoulder that limits the rotations of the lever member. 
     
     
         5 . The container of  claim 2 , wherein the lever member support body comprises:
 a circular support plate that is mounted in the mounting part;   a plurality of protrusion pieces that extend in an upward direction from the support plate and are inserted in the sealing member and the fixing plate;   a plurality of connection pins that extend in a central direction from an inner circumferential surface of the support plate; and   a rotational guide piece that is connected to a pair of facing connection pins among the plurality of the connection pins and that protrudes in an upward direction and supports the lever member and guides the operations of the lever member.   
     
     
         6 . The container of  claim 5 , wherein in the sealing member and the fixing plate is formed an engaging hole through which the protrusion piece passes, and in the protrusion piece is provided an engaging shoulder that prevents the lever member support body from disengaging from the engaging hole. 
     
     
         7 . The container of  claim 4 , wherein in the top of the rotational guide piece is provided a rotational guide protrusion to which the lever member is engaged, and in both sides of the bottom of the lever member is provided a protrusion engaging groove that is engaged to the rotational guide protrusion. 
     
     
         8 . The container of  claim 4 , wherein the lever member comprises:
 a pressing part that is engaged to the pair of the rotational guide protrusions so that it can rotate in a direction or in the other direction by a user's pressing;   a semicircular sealing guide part that is engaged to the bottom of the pressing part and that is positioned between the pair of the rotational guide pieces and that rotates as either one end portion or the other end portion of the pressing part rotates; and   a sealing guide protrusion that covers part of the sealing guide part and comes into contact with the bottom of the lever member engaging groove when the pressing part is in a horizontal state and that ascends the rotational guide piece and guides the pressing of the sealing member.
