Description

Description EASY OPENING AIRTIGHT CONTAINER

Technical Field

[1] The present invention relates to a one-touch airtight container, and more particularly, to a one-touch airtight container that can be easily closed and opened using a one-touch type cover without locking wings. Background Art

[2] Conventional airtight containers are formed of an authentic resin or stainless steel and of which cover is formed with locking wings to provide secure airtight sealing.

[3] An example of conventional airtight containers is illustrated in FIG. 7. The airtight container of FIG. 7 includes a vessel and a cover for closing an opened top portion of the vessel. A ridge is formed along a top periphery of the vessel, and locking wings 23 extend from a periphery of the cover for coupling with the ridge.

[4] However, the conventional airtight container of FIG. 7 is disadvantageous since the conventional airtight container should include the ridge on the vessel and locking wings 23 on the cover additionally. Therefore, it is difficult and takes many costs to manufacture the conventional airtight container. Furthermore, it is inconvenient for a user to open or close the cover using the plurality of locking wings 23. Disclosure of Invention Technical Problem

[5] Accordingly, the present invention is directed to an airtight container that substantially obviates one or more problems due to limitations and disadvantages of the related art.

[6] (1) An object of the present invention is to provide an airtight container that provides secure airtight sealing without an additional structure on a top periphery of a vessel.

[7] (2) Another object of the present invention is to provide an airtight container that provides secure airtight sealing without locking wings on a cover.

[8] (3) Another object of the present invention is to provide a convenient airtight container including a grip for charging or discharging air into or from the airtight container.

[9] (4) Another object of the present invention is to provide an airtight container that can be closed or opened by touching a cover only once. Technical Solution

[10] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a one- touch airtight container having a cover for airtightly closing a top of a polygonal or circular vessel, [11] the one-touch airtight container being characterized in that the cover include an outer ridge formed along a bottom periphery and an inner ridge spaced apart from the outer ridge, and [12] a silicon sealant member is inserted between the outer ridge and the inner ridge.

Advantageous Effects

[13] The airtight container of the present invention provides the following advantageous effects. [14] (1) The airtight container has a beautiful appearance since the airtight container provides secure airtight sealing without an additional structure on a top periphery of a vessel. [15] (2) The airtight container can be easily manufactured since locking wings are not formed on a cover. [16] (3) The airtight container can be conveniently used since air can be charged or discharged into or from the airtight container using a grip. [17] (4) The airtight container can be conveniently used since the airtight container can be closed or opened by touching a cover only once.

Best Mode for Carrying Out the Invention

[25] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. [26] Referring to FIGs. 1 to 6, a one-touch airtight container of the present invention includes a cover 100 for airtightly closing a top of a polygonal or circular vessel 300. The one-touch airtight container is characterized in that the cover 100 includes an outer ridge 110 formed along a bottom periphery and an inner ridge 120 spaced apart from the outer ridge 110, and a silicon sealant member 200 is inserted between the outer ridge 110 and the inner ridge 120. The silicon sealant member 200 includes a body 210 inserted between the outer ridge 110 and the inner ridge 120, and a grip 220 extending outward from the body 210.

[27] The outer ridge 110 extends downward from a peripheral edge of the cover 100.

The inner ridge 120 extends from a bottom surface of the cover 100 in parallel with the outer ridge 110 and is spaced a predetermined distance from the outer ridge 110.

[28] The outer ridge 110 has a height higher than or equal to that of the inner ridge 120.

[29] The silicon sealant member 200 is formed of a silicon material and has a reverse U- shaped section. The silicon sealant member 200 includes a center groove 231 and protrusions 232 in the groove 231.

[30] A top edge of the vessel 300 is inserted into the groove 231 when the vessel 300 is airtightly closed by the cover 100.

[31] Alternatively, the silicon sealant member 200 can have a reverse L-shaped section.

In this case, a protrusion 232 is formed on the silicon sealant member 200 near the outer ridge 110.

[32] The body 210 of the silicon sealant member 200 can include a main portion 234 having a rectangular section, a lead 236 extending from a side portion of the main portion 234 in contact with the outer ridge 110 and including a protrusion 232, and a blocking layer 238 extending from an end of the lead 236 for enclosing a lower end of the outer ridge 110.

[33] When the body 210 includes the main portion 234, the lead 236, and the blocking layer 238, it is preferable that the outer ridge 110 be higher than the inner ridge 120.

[34] A plurality of recesses 114 can be formed upwardly from a lower edge of the outer ridge 110. In this case, the cover 100 can be coupled to the vessel 300 more smoothly.

[35] The grip 220 is formed at a corner of the body 210. The grip 220 includes an anti- slip ridge 224 on an edge.

[36] A pressure-release groove 222 is formed at the corner of the body 210 where the grip 220 is formed. The pressure-release groove 222 is formed in top and side surfaces of the corner. When the grip 220 is pulled, the body 210 is deformed and thus air moves into or out of the vessel 300 through the pressure-release groove 222.

[37] Hereinafter, a method of using the one-touch airtight container and an operation of the one-touch airtight container will be described according to an embodiment of the present invention.

[38] When the cover 100 is coupled to the vessel 300 after placing something into the vessel 300, the upper edge of the vessel 300 makes tight contact with the silicon sealant member 200 so that the vessel 300 can be airtightly closed.

[39] Here, the vessel 300 can be closed more tightly owning to the protrusion 232.

Furthermore, when the pressure inside the vessel 300 is high due to air excessively charged into the vessel 300 when the cover 100 is coupled to the vessel 300, some air can be discharged from the vessel 300 through the pressure-release hole 222 by pulling the grip 220 while depressing the cover 100. The vessel 300 can be closed more tightly by discharging air in this way.

[40] When it is intended to open the vessel 300, the cover 100 can be easily detached from the vessel 300 by pulling the grip 220 upward after putting some air into the vessel 300 through the pressure-release hole 222 by pulling the grip 220 in a lateral direction.
