[invention Title]
DEHUMIDIFYING STRUCTURE FOR CONTAINER CAP [Technical Field] The present invention relates to a dehumidifying agent, and more particularly, to a dehumidifymg structure for a container cap, in which a dehumidifymg portion is coupled to the inner upper portion of the container cap to enable smooth ventilation, thereby enabling a dehumidifymg agent to safely perform a dehumidifymg action without leaking out. [Background Art]
Generally, fine granular silica gel is used as a dehumidifymg agent. In order to prevent the contents inside a container from deteriorating or being damaged by moisture, the dehumidifymg agent is usually contained in a porous package made of a fiber material, a paper bag, or a plastic container according to a kind of its contents or a packing form.
Recently, a dehumidifymg agent container which separately stores the dehumidifymg agent has been coupled to the inner upper side of a container cap.
Referring to FIG. 1, a dehumidifying agent container 1 has a container body 10 which has a cylindrical shape that is opened in one direction and accommodates a dehumidifymg agent S in a granular form therein through its opened end portion 11; a first safety plate 20 which is coupled to the opened end portion 11 of the container body 10 and has a plurality inflow holes 21 formed therein in order to prevent leakage of the dehumidifymg agent S; and a second safety plate 30 made of paper, which closely contacts the first safety plate 20 for air circulation.
Referring to FIG. 2, the dehumidifymg agent container 1
is coupled to a coupling portion 3 within the container cap 2 in such a way that the second safety plate 30 is located in a lower portion of the dehumidifying agent container 1, thereby absorbing and thus removing moisture remaining in a container 4.
However, when the dehumidifymg agent container 1 is used for a long period of time, the dehumidifymg agent S which has been powered may get mixed m contents such as food or medicines stored in the container 4 by contacting moisture and the air and thus contaminate the contents. Furthermore, the dehumidifymg agent container 1 is inconvenient to use for a one-touch type container cap due to its large size and is not economical due to increase in the manufacturing cost.
[Disclosure] [Technical Problem]
Accordingly, the present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide an economical dehumidifying structure for a container cap, in which an air- permeable member for preventing leakage of a dehumidifymg agent is formed at an upper portion of a storage member, thereby preventing the dehumidifying agent from being mixed in contents, and a dehumidifying portion is coupled to an upper portion of the container cap while being spaced apart from the upper portion by a predetermined interval, thereby facilitating a dehumidifying action and thus minimizing the size of the dehumidifymg portion.
[Technical Solution]
To achieve the above object, there is provided a dehumidifying structure for a container cap. The dehumidifying structure includes: the container cap comprising:
a main body having a coupling rib protruding downwardly from an inner top surface thereof and coupled to the inner wall of a container so as to maintain air- tightness between the main body and the container; a support protrusion which protrudes in a ring shape inwardly from an inner peripheral surface of an upper portion of the coupling rib in order to support a dehumidifying portion; and a guide protrusion formed radially on an inner top surface of the mam body in such a manner as to be spaced apart from the dehumidifymg portion by a predetermined interval, thereby enabling smooth ventilation, and the dehumidifymg portion comprising: a storage member coupled to an inner portion of the container cap, the storage member having a storage space or storing a large amount of dehumidifymg agent therein, and an air inflow face extending outwardly from an outer peripheral edge portion of the storage member in order to facilitate air inflow; and an air-permeable member attached on the top surface of the storage member for allowing air to flow into the storage member therethrough. [Advantageous Effects]
As described above, according to the present invention, an air-permeable member is formed in an upper portion of a container cap, thereby preventing a dehumidifymg agent from being mixed in contents, such as food or medicines, stored in a container, and a dehumidifymg portion is coupled to an upper portion of the container cap while being spaced apart from the upper portion by a predetermined interval, thereby enabling smooth ventilation and thus allowing a stable dehumidifying action.
Moreover, the small size of the dehumidifying portion that stores a dehumidifymg agent makes it easy to open and close the container cap and reduces manufacturing cost, thus providing an economical advantage. [Description of Drawings]

To achieve the above object, embodiments of the present invention will be described in detail.
FIG. 3 is an exploded perspective view of a dehumidifymg structure for a container cap 100 according to an embodiment of the present invention, FIG. 4 is a cross- sectional view of the dehumidifymg structure according to an embodiment of the present invention, and FIG. 5 illustrates the used state of the dehumidifymg structure according to an embodiment of the present invention.
The dehumidifying structure according to an embodiment of the present invention includes the container
cap 100 and a dehumidifying portion 200. The container cap 100 includes a main body 110 having a coupling rib 111 protruding downwardly from an inner top surface thereof and coupled to the inner wall of a container 10 so as to maintain air-tightness between the main body and the container; a support protrusion 112 which protrudes in a ring shape inwardly from an inner peripheral surface of an upper portion of the coupling rib 111 in order to support a dehumidifymg portion 200; and a guide protrusion 113 formed radially on an inner top surface of the main body 110 in such a manner as to be spaced apart from the dehumidifymg portion 200 by a predetermined interval, thereby enabling smooth ventilation. The dehumidifymg portion 200 includes a storage member 210 coupled to an inner portion of the container cap 100, the storage member having a storage space 211 for storing a large amount of dehumidifymg agent S therein; an air inflow face 212 extending outwardly from an outer peripheral edge portion of the storage member 210 in order to facilitate air inflow; and an air-permeable member 213 attached on the top surface of the storage member 210 for allowing air to flow into the storage member therethrough. Now, a detailed explanation of the dehumidifymg structure according to an embodiment of the present invention will be provided below.
The dehumidifymg portion 200 further includes a plurality of air guide protrusions 214 radially protruding on the top surface of the storage member 210.
The storage member 210 is polygonal in shape. Now, the used state of the dehumidifying structure according to an embodiment of the present invention will be described.
First, as illustrated in FIG. 3, after a large amount of dehumidifymg agent S is stored in the storage space 211 of
the storage member 210, the air-permeable member 213 having a fine air hole formed therein is attached onto the storage member 210, thereby obtaining the dehumidifying portion 200.
The dehumidifying portion 200 is disposed under the container cap 100 of a one-touch opening/closing type and then pressure is applied such that the outer circumferential face of the storage member 210 closely contacts the inner circumferential face of the coupling rib 111 of the container cap 100. Then, an end portion of the storage member 210 becomes inserted into an upper portion of the support protrusion 112 protruding in a ring shape, and the air- permeable member 213 on the storage member 210 closely contacts the guide protrusion 113 protruding in an inner upper portion of the container cap 100, thus being coupled to the inner top face of the container cap 100 while being spaced apart from the inner top face of the container cap 100 by a predetermined interval.
When the container cap 100 coupled to the dehumidifying portion 200 is inserted into a water intake portion of a container 4, the coupling rib 111 of the container cap 100 closely contacts the inner circumferential face of the container 4 and thus the container cap 100 can be tightly coupled to the container 4.
In this state, moisture remaining within the container 4 flows upwardly through the air inflow face 212 of the storage member 210 and the space of the inner circumferential face of the coupling rib 111, and the inflow moisture flows into a space made between the air-permeable member 213 and the guide protrusion 113. Thus, the dehumidifying agent S absorbs the moisture, thereby preventing the contents of the container 4 from deteriorating or decaying.
Since the storage space 211 for storing the dehumidifying agent S is opened upwardly in the storage member 210, the dehumidifying agent S that is powered by long-term use can safely absorb moisture without being mixed in the contents of the container A .
According to another embodiment of the present invention, as illustrated in FIG. 6, an air guide member 214 radially protrudes on the top face of the storage member 210 in order to closely contact the inner top face of the container cap 100, thereby facilitating a dehumidifying action.
According to still another embodiment of the present invention, as illustrated in FIG. I 1 the storage member 210 of the dehumidifying portion 200 is formed in a polygonal shape in order to be coupled to the inner side of the container cap 100.
The dehumidifying portion 200 can also be applied to a container cap that is opened and closed by screw rotation as well as the container cap 100 that is opened and closed by one touch action. [industrial Applicability]
As set forth above, according to the present invention, an air-permeable member is formed in an upper portion of a container cap, thereby preventing a dehumidifying agent from being mixed in contents, such as food or medicines, stored in a container, and a dehumidifying portion is coupled to an upper portion of the container cap while being spaced apart from the upper portion by a predetermined interval, thereby enabling smooth ventilation and thus allowing a stable dehumidifying action. Moreover, the small size of the dehumidifying portion that stores a dehumidifying agent makes it easy to open and close the container cap and reduces manufacturing cost, thus
providing an economical advantage.
