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.

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.

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.
As described above, optimal embodiments have been disclosed in the drawings and the specification. Although specific terms have been used herein, these are only intended to describe the present invention and are not intended to limit the meanings of the terms or to restrict the scope of the present invention as disclosed in the accompanying claims.
