DESCRIPTION OF EXEMPLARY EMBODIMENTS

(5) Hereinafter, a sealing packing 100 coupled to a container lid according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings. First, it is also noted that like reference numerals denote like elements in appreciating the drawings. In describing the present disclosure, detailed descriptions related to well-known functions or configurations will be ruled out in order not to unnecessarily obscure subject matters of the present disclosure.

(6) Referring to FIG. 2 or 3, the sealing packing 100 coupled to a container lid according to an embodiment of the present disclosure is largely composed of an airtight plate 110, an elastic support rack 120, and a pressing member 130.

(7) First, the airtight plate 110 will be described. The airtight plate 110 is a component coupled to correspond to a position of a first air passage hole 11 formed at an upper side of a container lid 10, as shown in FIG. 1, 2 or 4, and a second air passage hole 111 communicating with the first air passage hole 11 is formed in a center of the airtight plate 110 to change pressure in the container, thereby discharging air in the container 20 to an outside or allowing air to be introduced from the outside into the container 20.

(8) Meanwhile, as shown in FIG. 5, the second air passage hole 111 preferably has a size that causes a lower central portion of the pressing member 130 to be fitted into the second air passage hole 111 without causing forced fitting in a state in which the pressing member 130 is turned over as a user presses a central portion of the pressing member 130 with a finger.

(9) In addition, the airtight plate 110 is connected to the pressing member 130, which will be described later, so that the pressing member 130 can be located at the upper side of the container lid 10.

(10) Next, the elastic support rack 120 will be described. As shown in FIG. 3 or 4, the elastic support rack 110 is a component made of an elastic material that is capable of elastic deformation, such as silicone, in which a plurality of protruding upwardly around an edge of the connection hole 111 formed in the airtight plate 110 is formed, and the elastic support rack 110 is connected to the pressing member 130 to guide the pressing member 130 to move up and down so that the pressing member 130 can be turned over or restored to its original position.

(11) In addition, a third air passage hole 121 through which air passes is formed between the elastic support racks 120, so that air passing through the first air passage hole 11 and the second air passage hole 111 is allowed to be discharged to the outside or outside air is introduced into the container 20, thereby changing pressure in the container 20.

(12) Next, the pressing member 130 will be described. As shown in FIG. 2, 3 or 4, the pressing member 130 is formed in a curved shape and is a component connected to the elastic support rack 120 while covering the upper portion of the airtight plate 110 to change the pressure in the container 20 depending on a variation, and the pressing member 130 is formed of an elastic material capable of elastic deformation, such as silicon and the like, and may include a pressurization chamber 131 and a folding guide groove 132.

(13) The pressurization chamber 131 refers to an inner space between the pressing member 130 and the airtight plate 110, and the pressurization chamber 131 becomes a vacuumed state or an atmosphere pressure state depending on a variation due to a pumping operation of the pressing member to guide a change of pressure in the container 20.

(14) The folding guide groove 132 is a kind of groove formed in a circular shape on an upper circumferential surface of the pressing member 130, and, as shown in FIG. 5, in the process of turning the pressing member 130 over by pressing the pressing member 130, the folding guide groove 132 guides an outer surface of the pressing member 130 at the boundary of the folding guide groove 132 to be bent and a lower outer surface of the pressing member 130 to be turned over in an upward direction, thereby enabling the pressing member 130 to be easily turned over.

(15) Meanwhile, the pressing member 130 has a semicircular cross-section so that the pressing member 130 can be turned over more easily than in the case of having a rectangular shape with corners.

(16) In addition, in the present disclosure, as shown in FIG. 4, a thickness of the pressing member 130 increases from an upper central portion to a lower end portion, thereby enabling pressing member 130 to be easily turned over.

(17) Hereinafter, an operation for releasing the sealed container 20, which is sealed using the sealing packing 100 coupled to the container lid, according to a preferred embodiment of the present disclosure will be described with reference to FIGS. 4 to 5.

(18) First, as shown in FIG. 4, when the sealing packing 100 coupled to the container lid according to the preferred embodiment of the present disclosure is in its original state, the container lid 10 and the container 20 are in a sealed state.

(19) Next, as shown in FIG. 5, when a user presses the upper central portion of the pressing member 130, the pressing member 130 is elastically deformed and the pressurization chamber 131 becomes a contracted state, and then, as shown in FIG. 6, when the pressing member 130 is totally turned over, air in the container 20 is discharged to the outside through the first, second, and third air passage holes 11, 111, and 121 to cause the container 20 to be an atmospheric pressure state, and accordingly, the ability of sealing between the container lid 10 and the container 20 may be lowered, the container lid 10 may be easily removed from the container 20.

(20) Conversely, when the pressing member 130 is deformed from the turned-over state to its original state and then the upper center portion of the pressing member 130 is pressed, the pressurization chamber 131 is changed to a contracted state from an expanded state, and then, when the user removes the pressure by moving a finger from the pressing member 130, the pressurization chamber 131 becomes the expanded state again so that the pressure in the container 20 is lower than atmospheric pressure, thereby bringing the container lid 10 and the container 20 to contact closely each other to form a sealed state.

(21) 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 embodiments and are not intended to limit the meanings of the terms or to restrict the scope of the present disclosure as disclosed in the accompanying claims.
