One-touch cap

Abstract

A one-touch cap enables a cover part to encompass a whole part cap body when the cover part is closed, so as to fundamentally prevent a phenomenon in which a gap between an upper end of the cap body and a lower end of the cover part is widened due to the continuous opening and closing of the cover part for the use of contents, thereby preventing the leakage of contents and the inflow of foreign substances.

1 . A one-touch cap comprises:
 a cap body coupled to an upper portion of the container body where contents are stored, and provided with a discharge hole for discharging contents stored in the container body; and   a cover part hinge-coupled to one side of the cap body and opening and closing the discharge hole by an upward and downward rotation,   wherein a hinge-coupling part is protrusively formed at a rear portion of the cap body such that the cover part can be hinge-coupled, wherein the cover part has a part of the rear portion which meets the hinge-coupling part cut open so as to prevent an interference with the hinge coupling part when the cover part is rotated upward and downward,   wherein the cover part encompasses a whole part of the cap body such that the cap body will not be exposed to the outside in a state of rotating to a downward direction and closing the discharge hole.   
     
     
         2 . The one-touch cap of  claim 1 , wherein a fixing protrusion is provided at an inner side of a front portion of the cover part such that the cover part can be fixedly coupled to the cap body in a state of rotating to a downward direction and closing the discharge hole, and at the cap body is provided a limitation protrusion which supports the fixing protrusion at a part that is met by the fixing protrusion and thereby limits rotation of the cap body to an upward direction. 
     
     
         3 . The one-touch cap of  claim 2 , wherein a handle part is provided at an outer side of a front portion of the cover part for making it easy for a user to grasp the cover part and to rotate to upward and downward directions.
