Title: One-touch cap

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a one-touch cap, in particular, a one-touch cap which 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 to prevent the leakage of contents and the inflow of foreign substances. 
     Generally, one-touch caps are configured to include a cap body which is coupled to an upper portion of a container body and having a discharge hole for discharging contents, and a cover part which is hinge-coupled to one side of the cap body, such that the discharge hole provided at the cap body can be opened and closed through an upward/downward rotation of the cover part. This type of ‘one-touch cap’ is disclosed in the registered utility model No. 20-0438528 (Hereafter it is called as ‘the registered utility model’). 
     The registered utility model in the above relates to a one-touch cap of cosmetic container including a body part ( 10 ) coupled to a cosmetic container and a cover part ( 20 ) coupled by means of a snap hinge at one side of the body part ( 10 ), 
     characterized in that interference prevention cutting parts ( 2 )( 2 ′) are formed at both sides of a snap hinge ( 1 ) which connects a top end of the body part ( 10 ) and a lower end of the cover part ( 20 ). 
     However, the one-touch cap as in the above is configured in a way that a lower end of the cover part ( 20 ) is seated on an upper end of the body part ( 10 ) when the cover part ( 20 ) is closed. However, a gap between an upper end of the body part ( 10 ) and a lower end of the cover part becomes widened because the upper end of the body part ( 10 ) and the lower end of the cover part ( 20 ) are continuously being contacted, such that there will arise problems that contents can be leaked and that the one-touch cap can be contaminated due to influx of foreign substances through the gap. 
     SUMMARY OF THE INVENTION 
     The present invention is disclosed to solve the problems described in the above, the present invention is to provide a one-touch cap, enabling a cover part to encompass a whole part of a cap body when a cover part is closed, such that it is possible 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 to prevent the leakage of the contents as well as the inflow of foreign substances. 
     To solve the problems in the above, a one-touch cap according to the present invention includes: 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, 
     characterized in a way that 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. 
     Furthermore, it is characterized in a way that 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. 
     Furthermore, it is characterized in a way that 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. 
     As described in the above, according to the present invention, by configuring that the cover part can cover a whole part of the cap body when the cover part is closed, it is possible to 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 to prevent the leakage of the contents and the inflow of foreign substances.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     Hereinafter, the present invention will be described in detail with reference to accompanying drawings. The same reference numerals provided in the drawings indicate the same members. 
       FIG. 1  is an exploded perspective view illustrating a configuration of a one-touch cap according to an exemplary embodiment of the present invention. 
       FIG. 2  is a side view illustrating a state that a cover part of the one-touch cap is opened according to an exemplary embodiment of the present invention. 
       FIG. 3  is a side view illustrating a state that a cover part of the one-touch cap is opened according to an exemplary embodiment of the present invention. 
       FIG. 4  a rear view illustrating a state that a cover part of the one-touch cap is opened according to an exemplary embodiment of the present invention. 
       FIG. 5  is a cross-sectional view illustrating a state of the one-touch cap being coupled to a container body according to an exemplary embodiment of the present invention. 
     Referring to  FIGS. 1 to 3 , a one-touch cap according to the preferred embodiments of the present invention includes a cap body  100  and a cover part  200 . 
     The cap body  100 , coupled to an upper portion of the container body  10  where contents are stored, has a discharge hole  110  formed at a center portion thereof for discharging contents stored in the container body  10 . 
     Furthermore, at the cap body  100  is provided a limitation protrusion  120  which supports a fixing protrusion  220  of a cover part  200 , to be described later, in a state that the cover part  200  closes the discharge hole  110 . The limitation protrusion  120  is possible to be formed simply at an upper portion of an front portion of the cap body  100  which meets the fixing protrusion  220 , and also possible to be formed to encompass an upper outer circumferential portion of the cap body  100 . 
     In the present invention, it is characterized in that a hinge coupling part  130  is protrusively provided at a rear portion of the cap body  100  such that a cover part  200  can be hinge-coupled thereto. By equipping the hinge coupling part  130  protruded from an outer circumferential portion of the cap body  100  and placing a hinge  240  separated from the cap body  100 , it is possible that the cover part  200  can cover a whole part of the cap body  100  and thereby close the cap body  100  when the cover part  200  is rotated to a downward direction and closed. At this moment, the perimeter of the cover part  200  is configured to be bigger than the perimeter of the cap body  100  so as to encompass the whole part of the cap body  100 . 
     Furthermore, the hinge coupling part  130  is preferred to have a predetermined height from a bottom dead point of the rear portion of the cap body  100  so as to prevent a gap with a cut open part of the cover part  200  from being formed in a state the cover part  200  covers the whole part of the cap body  100 . 
     The cover part  200 , hinge-coupled to one side of the cap body  100  and opening and closing the discharge hole  110  by an upward and downward rotation, is provided with an opening and closing protrusion  210  which opens and closes the discharge hole  110  at an inner side thereof. 
     Furthermore, a fixing protrusion  220  which is supported by a limitation protrusion  120  is provided at an inner side of a front portion of the cover part  200  such that the cover part  200  can be rotated to a downward direction and be fixedly coupled to the cap body  100  in a state of closing the discharge hole  110 . Due to this, the fixing protrusion  220  normally in a storing state is supported by the limitation protrusion  220  and prevents the cover part  200  from rotating to an upward direction and opening, and then is released from the limitation protrusion  120  when a user applies a certain amount of force, and makes it possible for the cover part  200  to rotate to an upward direction. 
     In the present invention, it is characterized in that the cover part  200  is configured to rotate in an upward and downward direction in a state of being coupled by means of a hinge  240  to the hinge coupling part  130 , and configured to cover the whole part of the cap body  100  such that the cap body  100  will not be exposed to the outside in a state the cover part  200  rotates to a downward direction and closes the discharge hole  110 . To attain this end, a height of the cover part  200  is preferred to be high enough to receive the cap body  100 . 
     Furthermore, the cover part  200  is formed with a part of a rear portion thereof meeting the hinge coupling part  130  cut open, and more preferably, formed with a shape corresponding to the hinge coupling part  130  such that a gap will not be formed between the hinge coupling part  130  and the cover part  200 . 
     Meanwhile, it is preferred that a handle  230  is equipped at an outer side of a front portion of the cover part  200  such that a user can easily grasp and rotate the cover part  200  to an upward and downward directions. 
     The present invention, as described in the above, is characterized to be composed of a new structure of a one-touch cap wherein the cover part  200  encompasses a whole part of the cap body  100  when the cover part  200  is closed. Accordingly, due to this structure wherein an upper end of the cap body  100  and a lower end of the cover part  200  do not meet each other when the cover part  200  is opened and closed, it is possible to fundamentally prevent the phenomenon in which a gap between an upper end of the cap body and a lower end of the cover part is widened by a continuous opening and closing of the cover part  200 .
