Description

Lid for airtight container with valve mechanism to keep the inside of the container in a closed vacuum

The present invention relates to a closed container lid having a valve mechanism capable of keeping the inside of the container in a closed vacuum state.

As a sealed container that can be kept fresh in a vacuum state and keeps the food stored therein fresher, the invention disclosed in Korean Utility Model Publication No. 20-0146603 (registered on Feb. 27, 1999) can be cited. have.

As described above, the pre-registration design forms a recess 8 on one side of the container lid 2, and is formed by a separation wall 9 in which the valve hole 6 and the through hole 12 are perforated. The inside and outside of the container are divided up and down, and the operation valve 7 is settled in the groove 8 at the upper part of the separation wall 9, and engaged with the guide groove 10 formed on the inner wall surface of the groove 8. A flute having a flute hole 13 formed in the lower part of the dividing wall 9 to pressurize the actuating valve 7 by the pressing protrusion 5 of the pressing button 3 having the locking protrusion 14 that slides up and down. The board 11 is attached.

According to the above configuration, after closing the container lid 2 to the container body 15 by pressing the surface of the convex curved container lid with a finger, the container inner portion 16 is pressurized due to volume reduction, the container higher than atmospheric pressure The internal pressure reaches the operation valve 7 through the flute hole 13 and the holes 6 and 12 to push up the operation valve 7, so that the air in the container 16 communicates with the outside. It is discharged to the outside through the open holes (6) 12, at which time the internal air passes through the flute hole (13) to make a flute sound (beep) to inform that the air is discharged to the outside .

Subsequently, when the finger is released from the container lid surface to release the pressing force, the container lid surface 2a tries to return to its original state, but at this time, the actuating valve 7 is lowered due to its own weight and negative pressure to be adsorbed onto the surface of the separating wall 9. (6) (12) is blocked so that the inflow of air from the outside does not make the container body 16, the negative pressure (vacuum pressure) is acting, accordingly the container lid (2) is difficult to peel off, the container The vacuum in the interior 16 allows for longer shelf life of food.

On the other hand, in order to release the vacuum pressure inside the container and peel off the air lid (2), the pressing button (3) is pressed, and the lower end of the pressing projection (5) that is lowered accordingly to the lower portion of the center of the operation valve (7) Press to attach to the through hole 12 formed in the central portion of the separation wall (9).

In such a state, the outer periphery of the disk-shaped actuating valve 7 is lifted from the separating wall 9 so that the valve hole 6 is opened. Accordingly, air is supplied from the outside through the valve hole 6 to the inside of the container ( 16, the vacuum inside the container 16 is destroyed and becomes atmospheric pressure to achieve the equilibrium pressure inside and outside the container, the container lid 2 can be peeled off without resistance from the container body 15.

According to the above-mentioned line design, there is an advantage in that the maintenance and destruction of the vacuum inside the container is easy, but it is pointed out that the following problems in terms of structure.

That is, in coupling the pressing button 3 in the groove 8, the outwardly engaging projections 14 should be engaged with the inside of the guide groove 10, so that it is difficult to pass the stepped diameter of the upper side. It is difficult to assemble the assembly is not easy, and when the pressing button (3) is inclined and caught in the process of pressing the pressing button 3, the up and down operation becomes incomplete.

In addition, the operation valve 7 and the pressurization button 3 are separated from each other, and are simply accommodated in the recess 8, and the operation valve 7 has a simple flat structure, and thus the function of the operation valve 7 is unstable. There is a problem.

Therefore, the present invention has been proposed in view of the above, and its purpose is to improve the assembly of the members constituting the device, and to ensure the responsiveness and high accuracy of the valves during vacuum and vacuum destruction inside the container, and the air inside the container. It is to provide a closed container lid of the structure that can be quickly discharged and at the same time improve the size of the flute produced by the air discharge.

It will be described below with reference to the accompanying drawings, the configuration of the subject innovation.

In Figure 1, the container lid of the present invention having a valve mechanism is indicated by the reference numeral 30, the container body containing the food is indicated by the reference numeral 31.

The upper surface 32 of the container lid 30 is formed with a valve mechanism mounting recess 33 having a circular cross-sectional shape recessed downwardly, and the valve body 34 and the valve body 34 in the valve mechanism mounting recess 33 are formed. The press button 35 used to press and operate the valve body 34 is installed to be accommodated.

The valve seat 36 forming the bottom surface of the valve mechanism mounting recess 33 is provided with a valve hole 37 which communicates with the upper and lower spaces, that is, inside and outside the container.

It is raised around the valve hole 37 so as to protrude to the upper side than the seat face 39 of the valve seat 36 (a groove formed by digging the bottom surface in a thin depth) by being cut by a plurality of slit grooves 38. A plurality of arc-shaped protrusions 40 are formed, and air passages 41 are formed in the slit grooves 38 so as to extend outward.

The air flow passage 41 is formed to be lowered than the seat surface 39 of the valve seat 36, and at least one or more of the circular inner wall surface 42 of the valve seat 36 (4 in the illustrated embodiment). The air discharge passage 43 of the dog is formed radially and is dug outwardly in the shape of a furrow.

And the outer end of the air flow passage 41 is formed to be located in the inner side than the outer periphery of the valve body 34, it is preferable to form on the coaxial line with the air discharge passage 43 in plan view.

A hollow cylindrical body 44 is forcibly fitted to the inner wall member 45 having the same cylindrical shape in the valve mechanism mounting recess 33, and a stopper stepped at an upper end of the cylindrical body 44 bent toward the center side thereof. 46 is provided, and a plurality of guide protrusions 47 extending in the vertical direction protrude at regular intervals on the inner surface of the cylindrical body 44.

The pressing button 35 has a flange surface 48 that extends horizontally toward the outside, and a pressing protrusion 49 that protrudes vertically downward from the center lower portion thereof, and the flange surface 48 includes: Guide grooves 50 are formed to receive and engage the guide protrusions 47 so that the guide protrusions 47 and the guide grooves 50 are engaged in a spline form.

The pressure button 35 is assembled by fitting the guide grooves 50 to the guide protrusions 47 at the lower portion of the cylindrical body 44, and then the valve body 34 at the lower end of the pressing protrusions 49. And the cylindrical body 44 is fitted to the valve mechanism mounting recess 33.

In the assembled state as described above, the outer circumference of the valve body 34 having an outer diameter close to the diameter of the seat surface 39 of the valve seat adheres close to the edge of the seat surface 39 (thus the valve body 34). Is prevented from flowing), and in this state, the flange surface 48 of the pressing button 35 is positioned at a lower portion having a distance from the stopper step 46 at the upper end of the cylindrical body 44. In this way, the valve body 34 and the pressure button 35 are allowed to move vertically upward.

The valve body 34 is formed of a soft body such as rubber, in particular, a silicone rubber having good elasticity, and is formed to be curved like a sucker or a contact lens, so that the outer periphery is in close contact with the valve seat 36, while It increases toward the side has a degree of curvature that does not interfere with the protrusion (40).

In addition, although the cross-sectional shape of the protrusion 40 is illustrated as a rectangle, it may be configured to be curved along the curved shape of the valve body 34 by eliminating the corner angle of the outer side of the protrusion 40.

A substantially cylindrical flute mounting member 51 protrudes from the lower portion of the valve seat 36, and a flute plate member 52 is fitted therein, and the flute plate member 52 is upwardly downward. The flute hole 53 provided with one taper hole is formed.

Here, reference numeral 54 protruding to one side of the flute plate member 52 is a handle for attaching and detaching the flute plate member 52.

In addition, reference numeral 55 denotes a lock wing, 56 denotes a locking protrusion fitted into the locking hole 57, and reference numeral 58 denotes a packing for sealing the inside and outside of the container when the container lid 30 is mounted on the container body 31. As a configuration of the lock wing 55 is not necessarily required in the present invention, detailed description thereof will be omitted.

The operation of the present invention will be described below.

When food is to be stored, put the food in the container body 31, cover the container lid 30, and then rotate the lock wing 55 to lock the locking hole 57 to the locking projection 56 container lid 30 ), And then press down on the upper surface 32 of the container lid 30 (which may be configured to be convex upward with a portion relatively higher than the periphery of the periphery).

When the upper surface 32 is pressed and lowered by the finger force, the internal air pressure rises above the atmospheric pressure due to the volume reduction of the container inner 59, and this rising air pressure reaches the entire container, and the open flute hole 53 is opened. As the compressed air is ejected to the upper side, it makes an audible flute sound, which informs you that the air is going out.

The air passing through the flute hole 53 acts on the valve body 34 via the valve hole 37, and the valve body 34 is lifted by this air pressure to be spaced apart from the valve seat 36. Accordingly, the air flows out in the order of the slit groove 38, the air flow passage 41, the air discharge passage 42 to the outside, and in this state the inside and the outside of the container is in equilibrium with the same atmospheric pressure.

Next, when the finger force holding the upper surface 32 is removed, the restoring force which tries to raise the pressed upper surface 32 to the original position acts.

However, at the same time, the air pressure for pushing up the valve body 34 is also eliminated, and the valve body 34 is lowered by its own weight with the pressurizing button 35 to be in close contact with the seat 39 of the valve seat 36 so as to close the valve hole ( The communication state of 37) is blocked.

In such a state, air is prevented from entering the inside of the container 59 through the valve hole 37 from the outside, and the upper surface 32 of the container lid is subjected to a restoring force to swell upward, and a vacuum pressure is formed inside the container. It will be.

In this way, if a vacuum pressure is formed in the container, even if the container lid without the lock wing, the container lid 30 is not removed by itself, and the food inside can be preserved longer by maintaining the vacuum state.

Next, when the container lid 30 needs to be opened, a vacuum breaker in the container 59 should be preceded. In this case, when the pressure button 35 is pressed with a finger, the center of the valve body 34 is pressed and lowered. Subsequently, when the central portion of the valve body 34 is pressed down to a position lower than the arc-shaped protrusion 40 projecting on the outer circumference of the valve hole 37, the outer circumferential edge 34a of the valve body 34 is the protrusion 40. It is lifted up as if it is turned over to the upper side by making it the seesaw turning point, and is spaced apart from the valve seat 36.

Accordingly, the air is introduced into the vessel 59 through the air discharge passage 43, the air passage 41, the slit groove 38, the valve hole 37, the flute hole 53, and the vacuum is destroyed. The container inner 59 is at atmospheric pressure, and the upper surface 32 of the container lid 50 is restored to its original state to lose the elastic restoring force.

Next, peel off the lock blade 55 and remove the container lid 30 from the container body 31 will be peeled off the container lid 30 without difficulty.

The present invention as described above, the valve body is fixed to the pressure button, and is assembled to the container lid through a separate cylindrical body is easy to assemble and install work, the valve body is formed in the sucker shape, the valve seat than in the simple flat shape The seating ability of the valve is improved, and the valve body pressurized during the vacuum break inside the container lifts the protrusion to the support point to open the valve hole, so the opening operation is sure and convenient, and the seating surface of the valve seat can accommodate the valve body. Since the size of the valve body is prevented from flowing, the air flow passage and the air discharge passage are prevented from causing interference between the valve seat and the valve body.

In addition, since the upper end of the flute hole has a tapered shape, a large amount of air is discharged quickly, and the flute sound is also increased, so that the vacuum formation inside the container can be easily recognized acoustically.
