Cosmetic container configured to be opened and closed by operation of cap in one-touch manner

Abstract

A cosmetic container includes a container body including an accommodation space for containing contents and a latching rim formed on an outer circumferential surface of an opening, and a cap configured to be unlocked from or locked to the container body in a one-touch manner, in which the cap is removed from or coupled to the container body by touching a push cap, vertical movement of which is controlled by an ascending/descending guide cap and a knock member elastically supported by an elastic member inside the ascending/descending guide cap, so that one or more opening/closing operation units, each of which has a hinge-coupling portion, perform an opening/closing operation to be caught by or released from the latching rim of the container body, thereby considerably conveniently and simply achieving an opening/closing manipulation of the cap with respect to the container body.

1 . A cosmetic container configured to be opened and closed by operation of a cap in one-touch manner, comprising:
 a container body ( 10 ) including an accommodation space ( 11 ) for containing contents and a latching rim ( 14 ) formed on an outer circumferential surface of an opening ( 12 ); and   a cap ( 20 ) configured to be unlocked from or locked to the container body in one-touch manner,   wherein the cap ( 20 ) is removed from or coupled to the container body ( 10 ) by touching a push cap ( 70 ), vertical movement of the push cap being controlled by an ascending/descending guide cap ( 40 ) and a knock member ( 50 ) elastically supported by an elastic member ( 60 ) inside the ascending/descending guide cap, so that one or more opening/closing operation units ( 80 ), each having a hinge-coupling portion, perform an opening/closing operation so as to be caught by or released from the latching rim ( 14 ) of the container body ( 10 ).   
     
     
         2 . The cosmetic container according to  claim 1 , wherein the cap ( 20 ) includes an inner airtight cap ( 30 ) for sealing an upper end of the opening in the container body ( 10 ) in an airtight manner, the ascending/descending guide cap ( 40 ) fixedly coupled to an upper portion of the inner airtight cap, the knock member ( 50 ) elastically supported by the elastic member ( 60 ) inside the ascending/descending guide cap, the push cap ( 70 ) fixedly coupled to the knock member and including latching ribs ( 74 ), the one or more opening/closing operation units ( 80 ) arranged in the push cap so as to be separate from one another, each having a portion hingedly coupled to support ribs ( 34 ) of the inner airtight cap and including an opening/closing wing ( 83 ) having a first latching step ( 83   a ) configured to be forcibly caught by the latching ribs and a second latching step ( 83   b ) configured to be caught by or released from the latching rim ( 14 ) formed on the outer circumferential surface of the opening in the container body, and an outer cap ( 90 ) coupled to an outer portion of the push cap, and wherein the cap is assembled into a unitary construction that is removed from or coupled to the container body ( 10 ) as a single unit. 
     
     
         3 . The cosmetic container according to  claim 1 , wherein the ascending/descending guide cap ( 40 ) includes rotation guide blocks ( 42 ) formed on an inner circumferential surface thereof and having inclined guide surfaces ( 42   a ), and first guide recesses ( 43 ) and second guide recesses ( 44 ) having different latching depths from each other and alternately arranged, each of the first guide recesses and the second guide recesses being defined between the rotation guide blocks and the second guide recesses having latching steps ( 44   a ) therein,
 the knock member ( 50 ) includes a rotation support member ( 52 ) fitted into the ascending/descending guide cap ( 40 ) such that an upper portion of the rotation support member is exposed outside through a through-hole ( 41 ) in the ascending/descending guide cap ( 40 ), and a cam member ( 51 ) elastically supported by the elastic member ( 60 ) and coupled to the rotation support member so as to rotate relative to the rotation support member, the cam member and the rotation support member including first guide protrusions ( 51   a ) and second guide protrusions ( 52   a ), respectively, and the first guide protrusions ( 51   a ) and the second guide protrusions ( 52   a ) having different latching lengths from each other, and   when the cap ( 20 ) is in a state of being locked to the container body ( 10 ), the first guide protrusions ( 51   a ) of the cam member ( 51 ) are caught by the latching steps ( 44   a ) of the second guide recesses ( 44 ) in the ascending/descending guide cap ( 40 ) so as to prevent the push cap ( 70 ) from ascending, and when the cap is unlocked from the container body, the cam member ( 51 ) is rotated in a predetermined direction by the rotation support member ( 52 ) and the first guide protrusions ( 51   a ) ascend along the first guide recesses ( 43 ) in the ascending/descending guide cap together with the second guide protrusions ( 52   a ) of the rotation support member so as to allow the push cap ( 70 ) to ascend.   
     
     
         4 . The cosmetic container according to  claim 1 , wherein the container body ( 10 ) further includes coupling protrusions ( 16 ) formed on an outer circumferential surface of an upper end of the opening ( 12 ), the opening/closing operation units ( 80 ) further include coupling protrusions ( 84 ) formed on surfaces thereof that face the outer circumferential surface of the upper end of the opening so as to mesh with the coupling protrusions ( 16 ) of the container body, and when the cap ( 20 ) is in a state of being locked to the container body ( 10 ), the coupling protrusions ( 16 ) mesh with the coupling protrusions ( 84 ) so as to prevent the container body ( 10 ) or the cap ( 20 ) from being unintentionally rotated. 
     
     
         5 . The cosmetic container according to  claim 2 , wherein the inner airtight cap ( 30 ) includes at least one of a short airtight pipe ( 31 ) for sealing an inner circumferential surface of an upper end of the opening ( 12 ) in the container body ( 10 ) in an airtight manner and an airtight ring ( 32 ) for sealing a top surface of the opening ( 12 ) in an airtight manner. 
     
     
         6 . The cosmetic container according to  claim 2 , wherein the outer cap ( 90 ) includes a cover ring ( 91 ) fixedly coupled to an inner circumferential surface of a lower end thereof.

The cosmetic container according to  claim 1 , wherein the push cap ( 70 ) further includes an attachment recess ( 71   a ) for receiving a name plate ( 75 ) attached thereto, the attachment recess being formed on a top surface of a push portion ( 71 ) of the push cap ( 70 ). 
     
     
         8 . The cosmetic container according to  claim 1 , wherein the container body ( 10 ) is formed to have a double structure including outer and inner container bodies ( 10   a  and  10   b ). 
     
     
         9 . The cosmetic container according to  claim 1 , wherein the elastic member ( 60 ) is a compressive coil spring.
