Rotary open/close-type tube container

Abstract

The present invention disclosed herein relates to a rotary open/close-type tube container. The container is configured in such a manner that when rotating an over cap in the open direction or the close direction, a rotary cap rotates together up to a certain section and a contents movement hole formed on a seal cap is opened/closed by raising/lowering the seal cap, whereby the contents movement hole is automatically opened/closed by a simple operation of opening/closing the over cap, thus providing a user convenience.

What is claimed is: 
     
         1 . A rotary open/close-type tube container comprising:
 a container body ( 100 ) configured to store contents therein, with a discharge part ( 110 ) provided at an upper portion of the container body ( 100 ) so that the contents are discharged through the discharge part ( 110 ), wherein the container body ( 100 ) further includes an extension part ( 120 ) extending upwards to an upper portion of the discharge part ( 110 ) and having a pair of perpendicular guide grooves ( 121 ) formed at both sides thereof, a closing protrusion ( 130 ) protruding upwards from an inner central portion of the discharge part ( 110 ), and a plurality of through holes ( 140 ) arranged to enclose the closing protrusion ( 130 ) so that the contents are allowed to pass through the through holes ( 140 );   a rotating cap ( 200 ) rotatably coupled to an upper portion of the container body ( 100 ), including a first thread ( 210 ) formed at an outer circumferential surface of the rotating cap ( 200 ), a pair of spiral grooves ( 220 ) formed at both sides of an inner circumferential surface thereof, and a discharge hole ( 230 ) formed at a central portion thereof so that the contents are discharged therethrough;   a sealing cap ( 300 ) configured to move upwards or downwards depending on rotation of the rotating cap ( 200 ) at the inside of the rotating cap ( 200 ), comprising a content-passing hole ( 310 ) formed at a central portion thereof and configured to be opened/closed by the closing protrusion ( 130 ), and guide protrusions ( 320 ) provided at an outer circumferential surface of the sealing cap ( 300 ) and configured to be inserted into the perpendicular guide grooves ( 121 ) and the spiral grooves ( 220 ); and   an over cap ( 500 ) including a second thread ( 510 ) at an inner circumferential surface thereof so as to be coupled to the first thread ( 210 ) of the rotating cap ( 200 ),   wherein, in a process of rotating and opening the over cap ( 500 ), the content-passing hole ( 310 ) of the sealing cap ( 300 ) opens before the over cap ( 500 ) opens.   
     
     
         2 . The rotary open/close-type tube container according to  claim 1 , wherein a rotating protrusion ( 520 ) rotates the over cap ( 500 ) at an inside of the over cap ( 500 ) such that the rotating cap ( 520 ) can be rotated along therewith when released from the thread coupling with the rotation cap ( 520 ), and a support protrusion ( 240 ) is interlocked with the rotating protrusion ( 520 ) at an outer circumferential surface of the rotating cap ( 200 ). 
     
     
         3 . The rotary open/close-type tube container according to  claim 2 , wherein when the over cap ( 500 ) rotates in an opening direction, the rotating cap ( 200 ) rotates along with the over cap ( 500 ) as the rotating protrusion ( 520 ) is engaged with the support protrusion ( 240 ), and after the sealing cap ( 300 ) is moved upwards and spaced away from the closing protrusion ( 130 ) to open the content-passing hole ( 310 ) in a process in which the guide protrusions ( 320 ) are moved from a bottom dead point of the respective spiral grooves ( 220 ) to a top dead point thereof by the rotation of the rotating cap ( 200 ), the over cap ( 500 ) independently rotates and a coupling threaded between the over cap ( 500 ) and the rotating cap ( 200 ) is released. 
     
     
         4 . The rotary open/close-type tube container according to  claim 1 , wherein, when the over cap ( 500 ) is rotated in a closing direction, the rotating cap ( 200 ) rotates along with the over cap ( 500 ) as the first thread ( 210 ) and the second thread ( 510 ) are engaged with each other, and, after the sealing cap ( 300 ) is moved upwards away from the closing protrusion ( 130 ) to open the content-passing hole ( 310 ) in a process in which the guide protrusions ( 320 ) are moved from a bottom dead point of the spiral grooves ( 220 ) to a top dead point thereof by the rotation of the rotating cap ( 200 ), the over cap ( 500 ) independently rotates and a coupling threaded between the over cap ( 500 ) and the rotating cap ( 200 ) is formed. 
     
     
         5 . The rotary open/close-type tube container according to  claim 1 , further comprising an applicator ( 400 ) coupled to an upper portion of the rotating cap ( 200 ) and configured to apply the contents to a skin of a user. 
     
     
         6 . The rotary open/close-type tube container according to  claim 5 , wherein an applicator support part ( 410 ) is coupled to an upper portion of the rotating cap ( 200 ) and is configured to support the applicator ( 400 ).
