The above objects, features and other advantages of the present invention will become more apparent by describing the preferred embodiments of the present invention in detail with reference to the accompanying drawings.

Hereinafter, a sealed container according to an embodiment of the present invention will be described with reference to the drawings.

1 to 10, the sealed container 100 according to an embodiment of the present invention includes a container body 110, a stopper 120, a locking member 130, and a locking force generation / release member 140. Include.

The container body 110 is hollow so as to accommodate food therein, the cross-sectional shape is formed in a circular or square shape.

In addition, the container body 110 has a sealing protrusion 112 protrudes in whole or in part along the inner wall of the inlet. Here, the sealing protrusion 112 is installed to have a curved surface of which the bottom surface is convex to the upper side as shown in FIG.

On the other hand, the sealing protrusion 112 has been illustrated that the bottom surface is formed in a curved shape, but not limited to this, it may be installed to be inclined so that the height is gradually lowered from the flat or the outside to the inside. In this case, when the sealing protrusion 112 is installed to have an inclined surface, the sealing body 132 may be inclined toward the inner wall surface of the container body 110 by the inclined surface, and thus may be in close contact with the inner wall surface.

Meanwhile, although the sealing protrusion 112 is illustrated as being integrally formed on the inner wall surface of the container body 110, the sealing protrusion 112 is not limited thereto and may be bonded to the inner wall surface of the container body 110.

The stopper 120 is formed in a shape corresponding to the inlet of the container body 110 to seal the container body 110 while seated at the inlet of the container body 110, the outer protrusion 122, the binding groove 124 and Packing 126.

The outer protrusion 122 protrudes downwardly upright to be adjacent to the outer wall of the container body 110 along the bottom edge of the stopper 120.

The binding groove 124 is a groove formed along the inner ceiling surface of the outer protrusion 122 of the bottom of the stopper 120 and is formed to insert the upper end of the stopper fixing part 134 of the locking member 130.

The packing 126 is formed in a ring shape provided along a ceiling surface between the outer protrusion 122 and the binding groove 124 and the outer wall of the stopper fixing part 134, respectively, and thus the edge of the container body 110. While keeping close to the upper surface and the upper surface of the sealing protrusion 112 to maintain a double airtight between the stopper 120 and the container body (110).

Locking member 130 is located on the lower side of the stopper 120, when the locking force generated / released when the binding to the bottom surface of the sealing projection 112 formed on the inner wall surface of the container body 110, the operation of the release member (140). And a deformable portion 131, a locking body 132, a folded portion 133, a stopper fixing portion 134, and a shaft portion 135.

The deformable portion 131 may be made of an elastic synthetic resin material or the like, and may be extended by an external force. And the deformable portion 131 is formed in a shape in which the central portion of the stopper 120 is convex upward when viewed in cross section.

At this time, the deformable portion 131 is formed larger than the distance between the opposed inner wall of the container body 110 during deformation to maintain a convex shape so as not to be reversed in the downward direction during the deformation process.

The lock body 132 is formed to be connected to the deformable portion 131 along the edge of the deformable portion 131, and is formed in a ring shape having a cross-section such as a circular or polygonal hollow formed therein.

On the other hand, in the present embodiment it is illustrated that the locking body 132 has a circular cross section.

In addition, the locking body 132 widens the circumference when it is supported on the bottom surface of the sealing protrusion 112 formed on the inner wall surface of the container body 110, as shown in Figure 7 and 8, so as to reduce the circumference at the original position It is formed of an elastic material.

On the other hand, the lock body 132 may be formed of a softer material than the deformation portion 131. In this case, by partially embedding a reinforcing material such as an iron core inside the locking body 132, the adhesion between the inner wall surface of the container body 110 and the bottom surface of the sealing protrusion 112 may be improved and the shape may be maintained.

Moreover, the lock body 132 is a container body when the longitudinal suction grooves 132a and 232a are radially formed along the outer circumferential surface of the lock body 132 and rotated to the inner wall surface of the container body 110 as shown in FIGS. 9 and 10. Since the vacuum adsorbed while being deformed on the inner wall surface of the 110 and the bottom surface of the sealing projection 112 is possible tight adhesion.

Meanwhile, the locking body 132 has one end connected to the folded portion 133 based on FIG. 1, and the other end spaced apart from the folded portion 133 by a predetermined distance is connected to the edge of the deformable portion 131.

Accordingly, the locking body 132 is supported so that the upper surface is folded by the folded portion 133 extending from the bottom of the stopper fixing portion 134 as shown in FIG. The folding unit 133 is rotated in the direction of the inner wall surface of the container body 110.

The folded portion 133 is connected to the “1” shape along the opposite surface between the locking body 132 and the stopper fixing portion 134, but is not limited thereto and may be changed to a zigzag or pleated shape.

At this time, the folded portion 133 is formed of a soft material because the locking body 132 is to be thermally rotated by the axis connected to the locking body 132.

The stopper fixing part 134 is formed in an upright shape so that the top is coupled to the binding groove 124 formed on the bottom of the stopper 120.

The shaft portion 135 is connected upright to the center of the upper surface of the deformable portion 131, the locking force generating / releasing member 140 is connected to the upper end passing through the center of the stopper 120.

The locking force generation / release member 140 lifts the shaft 135 to generate or release the locking force of the locking member 130, and includes a cover 141 and a lift adjusting member 142.

Cover 141 is formed in the shape of a dome covering the elevating control member 142, it is formed in a soft to enable deformation depending on whether or not pressed.

Lifting control member 142 is a known technique that operates in a push-up (push-up) method, when pressing the top down to lower the shaft portion 135 installed in the lower portion to maintain the lowered position of the shaft 135 When the upper end is pushed downward again, the shaft portion 135, which has been kept in the lowered state, is raised to the original position by the restoring force.

That is, when the cover 141 is pushed down once, the shaft portion 135 connected to the deformable portion 131 is lowered by the push-up method of the lift adjusting member 142 to maintain the lowered position of the shaft portion 135. Then, when the cover 141 is pressed down again, the shaft portion 135, which has been kept in the lowered state, is raised to its original position.

The sealing process of the closed container 100 according to an embodiment of the present invention is as follows.

First, as shown in FIGS. 1 and 2, the stopper 120 is seated at the inlet of the container body 110 in the state of putting food or the like inside the container body 110.

Next, referring to FIGS. 3 and 4, when the cover 141 of the locking force generation / release member 140 is pressed, the shaft portion 135 interlocked by the lifting control member 142 descends and the shaft portion 135 is lowered. The central portion of the convex deformable portion 131 connected to the bottom of the gradual descends.

At this time, when the center of the deformable portion 131 is lowered, the edge of the deformable portion 131 is extended and the locking body 132 is pushed in the direction of the inner wall surface of the container body 110, and the locking body 132 and the stopper fixing part ( Lock body 132 is rotated in the direction of the inner wall surface of the container body 110 to the iron contact portion 133 connecting the 134 is positioned under the sealing protrusion 112.

In addition, the locking body 132 has an adsorption groove 132a radially formed along the longitudinal direction on the outer circumferential surface of the bottom of the sealing protrusion 112 and the inner wall surface of the container body 110 adjacent to the bottom of the sealing protrusion 112. While being pressed and vacuum-adsorbed to the contact surface, the lock body 132 may be more strongly fixed to the inner wall surface of the container body 110.

Next, when the locking body 132 is absorbed and locked to the bottom surface of the sealing protrusion 112 and the inner wall surface of the container body 110 to prevent the shaft 135 from being raised by the locking force generation / release member 140. Will maintain its position.

Thereafter, when opening of the stopper 120 is required for ingestion of food or the like, the sealing process proceeds in the reverse order. That is, when the cover 141 of the locking force generating / release member 140 is pressed, the deformable portion to which the lower end of the shaft portion 135 is connected while the shaft portion 135 which is maintained in the lowered state by the elevating control member 142 is raised. The central portion of 131 rises.

The edge of the deformable portion 131 is reduced by the restoring force of the deformable portion 131 as the center portion of the deformable portion 131 rises.

Next, as the shaft portion 135 gradually rises, the edge of the deformable portion 131 is reduced so that the locking body 132 starts to rotate in the direction opposite to the inner wall surface of the container body 110 and is separated from the sealing protrusion 112. .

Next, the stopper 120 is separated from the container body 110.

Thus, in the present invention, when the center of the convex deformable portion 131 is lowered, the locking body 132 is rotated while the frame is deformed in the direction of the inner wall surface of the body 110 and interlocked with the inner wall surface of the container body 110. The bottom surface of the sealing protrusion 112 is in close contact. At this time, the locking body 132 is located below the sealing protrusion 112 while the locking body 132 is rotated in the direction of the inner wall surface of the container body 110 with the iron contact portion 133 and the sealing protrusion 112 Will be supported. As a result, unlike the conventional method of sealing only through the packing, the packing 126 and the locking groove 132a of the adsorption groove 132a allow multiple sealing while preventing the locking body 132 from being separated from the sealing protrusion 112. It can be locked to ensure a tight seal.

In addition, it can be opened and closed by one push-up method, which is convenient to operate and has the advantage of operating without using a lot of force.

On the other hand, in the present embodiment, when the container body 110 is circular, the locking body 132 extended in the circumferential direction is sealed in the container body 110 while the deformable portion 131 in the shape of a disc is extended in the radial direction from the center The bottom surface of the protrusion 112 is moved to interfere with the sealing protrusion 112.

However, when the container body 110 is a quadrangle, the edge portion of the deformable portion 131 having a rectangular plate shape may be deteriorated from the edge portion of the inner wall surface of the container body 110, unlike the edge portion. To this end, by rounding the corners of the locking body 132, the adhesion area to the inner wall edges of the container body 110 may be maximized. And the locking body 132 corresponding to the corner portion of the container body 110 may have a soft locking body 132 like a circular and the portion outside the corner is provided with a locking body 132 of a solid material, or the locking body 132 ) A reinforcing member such as an iron core can be buried inside so that a strong adhesion can be formed.

In addition, although not shown in the drawings, the reinforcement force of the deformable portion 131 when the locking body 132 extends in the circumferential direction by installing a reinforcing member, such as a date or cross, which is padded inside or outside the deformable portion 131. This can be done well.
