The present invention relates to a vacuum container for food preservation, and more particularly, to a vacuum container for food preservation that allows the inside of the container to be easily maintained in a vacuum state by pressing the soft lid in a one-touch manner.

In general, various kinds of foods such as vegetables and fish are easily oxidized and rot due to contact with other harmful substances such as oxygen or microorganisms contained in the air.

In addition, in the case of fermented food, the fermentation and ripening rate of the food proceeds too fast as the propagation of microorganisms is further activated, resulting in poor preservation.

Therefore, blocking the outside air in order to delay the fermentation and decay of food is the key, and the vacuum container is proposed for this.

The vacuum container not only blocks the outside air, but also puts the inside of the container into a low pressure vacuum lower than atmospheric pressure to prevent food waste.

Vacuum containers have thus made further technological advances in food preservation techniques, as compared to closed containers that simply prevent contact with outside air as before.

On the other hand, most of the vacuum container is provided with a vacuum generating structure that can generate a vacuum in the container lid, the vacuum generating structure provided in the container lid is generally an operation configuration consisting mainly of the pumping method.

The vacuum container having such a pumping vacuum generating structure has already been proposed and practiced by the present applicant in various ways, but the vacuum having a vacuum generating structure of the pumping method or other structures in addition to the configuration by the applicant. Containers are still being proposed and implemented in a great variety.

This pumping type vacuum container is mainly produced by the pimping structure formed on the lid of the container to generate a vacuum in close contact with the container body and the lid to maintain a stronger airtight force in this vacuum state, thereby keeping food safe for a long time. To be stored.

However, in order to have such a vacuum container, there is a very difficult problem in that a complex pumping structure must be formed in the container lid.

In other words, in order to make the interior of the container into a vacuum state, the container lid of the popping method must have a piston and a very complicated valve structure, and in particular, it is troublesome to require labor such as an operation force for pumping.

In particular, the vacuum container has a very uneconomical problem that is burdened with the cost of manufacturing and purchasing while taking too many parts.

Therefore, the present invention is devised to solve the above-mentioned problems of the prior art, and the present invention simply presses the lid in a one-touch manner to form the inside of the container as a vacuum state and at the same time can be sealed from the outside, which makes the operation easier. It is an object to provide a vacuum container for food preservation.

Figure 2 is an enlarged view of the main portion illustrating a coupling structure of the container body and the lid of the vacuum container for food preservation according to the present invention.

As shown in the figure, the container body 10 and the lid 20 are separated from each other by the upper end of the container body 10 facing each other and the lower end of the lid 20 in contact with the lower surface of the lid 20. (21) to be fitted and tightly maintained by the sealing ring 21 between the contact surfaces.

The container body 10 is configured to have a food receiving groove 11 to be opened upward, the food receiving groove 11 is a space formed so that a certain amount of food can be stored.

The lid 20 is configured to cover the upper portion of the container body 10 so as to be blocked from the outside, and particularly preferably have a soft physical property.

In other words, unlike the container body 10 having rigid physical properties, the upper portion of the upper surface of the lid 20 is formed to be curved upward at a certain height, while the downward curved paper can be deformed when pressed by hand. It is more preferable to have soft physical properties.

The lid 20 is provided with an operation groove 22 to be recessed downward in a predetermined size and depth on one side of the upper surface.

The operation groove 22 is formed so that the upper portion is wide and the lower portion is formed in a narrow shape, the bottom surface of the operation groove 22 to form a plane of a predetermined diameter or more.

The lid 20 is provided with an operation mechanism on one side, and the operation mechanism at this time is provided in the operation groove 22 when the operation groove 22 is formed on one side of the lid 20, and the operation groove ( In a configuration in which 22) is not formed, an operation mechanism may be provided directly on the upper surface of the lid 20.

In this way, the operation mechanism provided on one side of the lid 20 allows the inside of the container to communicate or seal with the outside air.

Figure 3 is an enlarged side cross-sectional view showing the operation mechanism of the vacuum container for food preservation according to the present invention, Figure 4 is an exploded perspective view of these operation mechanism.

As shown in the drawing, the bottom surface of the operation groove 22 allows the guide tube 30 to be formed in a tubular shape at a constant height from the center.

The guide tube 30 allows the air hole 31 to vertically penetrate the plate surface in the center of the bottom surface in the tubular interior.

In addition, in the cylindrical side wall of the guide tube 30, the pin guide hole 32 is formed to face each other from the top as shown in FIG.

The pin guide hole 32 is a shape of a long hole in which a hole having a constant diameter along a main surface has a predetermined inclination angle and is formed in a constant length, and in particular, the lower end portion is more preferably horizontally extended by a predetermined length.

The guide tube 30 is to be covered by the cap 40 to the outside, the cap 40 is shaped to open downward, the side of the guide tube 30 while surrounding the outside of the guide tube 30 It is a configuration to cover at the same time.

The cap 40 supports the cap 40 to be elastic up and down at all times while the lower end of the spring 41 is placed on the outer bottom surface of the guide tube 30 by allowing the spring 41 to be coalesced on the outer circumferential surface.

However, the upper surfaces of the caps 40 face each other to form pin holes 42 on the same horizontal line, and the pin holes 42 are on the same horizontal line as the pin guide holes 32 formed in the guide tube 30. The pin 43 is inserted into the pin hole 42 and the pin guide hole 32 from one side of the cap 40.

In other words, if the pin 43 is inserted through one pin hole 42 from one side of the cap 40 to penetrate the pin guide holes 32 on both sides, and the pin 43 is inserted into the other pin hole 42, the cap 40 ) Can be combined so as not to separate from the guide tube 30.

In the configuration in which the pin 43 is fitted into the cap 40, the portion where the pin hole 42 of the cap 40 is formed is formed with a ring-shaped groove by recessing the main surface at a constant height, but the packing 45 ) Is fitted so that the separation of the pin 43 fitted in the pin hole 42 is prevented.

In addition, a vertical exhaust hole 44 is formed on the upper surface of the cap 40 so as to communicate with the inside of the guide tube 30.

Exhaust hole 44 is to be formed as a plurality, in particular, it is preferable that the exhaust hole 44 is formed so as to vertically penetrate along the inner periphery of the guide tube 30 in the upper surface of the cap (40).

An inner bottom surface of the guide tube 30 allows a valve seat 50 having a predetermined thickness to be fitted to the inner diameter of the guide tube 30. The air hole 51 is formed to penetrate vertically with a diameter not larger than that of the hole 31.

Most preferably, at least one side of the valve seat 50 has a periphery around the air hole 51.

Meanwhile, the upper surface of the cap 40 is integrally coupled to the upper end of the support 60 to accommodate the ball 61 from the lower surface of the cap 40.

The support 60 has a cylindrical shape and has a settling hole 62 which allows the ball 61 to be partially projected downward at a predetermined diameter in the center of the bottom surface of the lower portion, and the pin 43 as a surface facing each other on the main surface of the upper portion. Pin hole 63 is formed to pass through.

The pin hole 63 may be formed to a diameter that the pin 43 can penetrate, or may be formed to have a shape of opening to an upper end by extending upwardly a hole having a diameter that the pin 43 can penetrate.

The support 60 is integrally coupled to the cap 40 so as to be inclined by a predetermined height, that is, the inclination height of the pin guide hole 32 formed in the guide tube 30 together with the cap 40 by the rotation operation of the cap 40. Ascend and descend.

The support 60 may be integrally coupled to the bottom of the upper surface of the cap 40 by ultrasonic welding in a state in which the ball 61 is embedded therein, but as shown in FIG. 6, the lower portion of the support 60 is It is more preferable to put the ball 61 from the bottom to the upper portion of the support 60 which is integrally coupled to the cap 40 to be provided by a prefabricated assembly simply by interference assembly.

Reference numeral 70 in the drawings is an air hole cover.

Referring to the operation by the present invention configured as described above are as follows.

Figure 7 is a side cross-sectional view showing an assembled state of the operation mechanism according to the present invention.

The subject innovation is to first lower the cap 40 by rotating the operation mechanism provided on one side of the lid (20).

At this time, the cap 40 is to maintain the state as lower as possible.

When the cap 40 is lowered, the lower end of the ball 61 embedded in the support 60 in the cap 40 comes into close contact with the valve seat 50 that is seated on the inner bottom surface of the guide tube 30. The air hole 51 formed in the valve seat 50 is blocked by its own weight.

When the air hole 51 is blocked, the inside of the container body 10 is placed in a state in which the inside is blocked from the outside.

8 to 10 are side and side cross-sectional views showing an operating state of the present invention.

In this state, if one side of the lid 20 is pressed with one hand and the center portion of the lid 20 is pressed as shown in FIG. 8, the guide of the operation mechanism provided with the outside of the inside of the lid 20 as one side of the lid 20 is blocked. The ball 61 is pushed up as shown in FIG. 9 while being guided through the air holes 31 and 51 of the pipe 30 and the valve seat 50.

At this time, the pressure generated by pressing the lid 20 should be at least greater than the weight of the ball (61).

And the lid 20 is preferably to have a soft physical property so that at least the middle portion can be pressed by a certain amount by hand operation.

Pressing the lid 20, the ball 61 is raised by the pressure for a while, the internal air is guided between the guide tube 30 and the support 60 to form a plurality of exhaust holes 44 in the upper surface of the cap 40 ) To be discharged to the outside.

When the discharge pressure of the inside is lower than the weight of the ball 61 while pressing the lid 20, the ball 61 falls back by its own weight to block the air hole 51 of the valve seat 50 as shown in FIG. Inflow of outside air from the state becomes blocked.

In other words, it only discharges the internal air, thereby blocking the inflow of external air, so that the inside of the container can be safely maintained in a tight vacuum in a slight vacuum.

Therefore, if a certain amount of food is accommodated in the container in advance, such that it is possible to keep the fresh state for a long time while the inflow of outside air is blocked.

Meanwhile, when the food is to be taken out from the sealed container, the cap 40 is rotated in the opposite direction as when the vacuum is to be formed as shown in FIG. 10.

When the cap 40 is rotated, the pin 43 formed to penetrate the inside of the cap 40 ascends along a predetermined slope along the pin guide hole 32 of the guide tube 30, as shown in FIG. The ball 60 which blocked the air hole 51 of the valve seat 50 by the support 60 which is integrally coupled to the cap 40 by the raise of the cap 40, and the outer peripheral surface of a lower end part in this support 60 inside. As the 61 is raised at the same time, the air hole 51 of the valve seat 50 is opened.

At the moment when the air hole 51 of the valve seat 50 is opened, the outside air that has been introduced into the cap 40 through the exhaust hole 44 of the upper surface of the cap 40 is instantaneously of the valve seat 50. The vacuum is released while flowing into the inside of the container through the air hole 51 and the air hole 31 inside the guide tube 30.

When the vacuum is released, the lid 20 may be easily opened while the adhesion force with the lid 20 which is strongly adhered at the upper end of the container body 10 is removed.

As such, the present invention allows the inside of the container to be in a vacuum state easily by simply pressing the center of the lid 20 placed on the container body 10 so as to be tightly sealed from the outside, and the closed state is simply a cap ( If only 40) to reverse the rotation can be easily opened because the vacuum is released, the lid 20 is very convenient.

In particular, the operation configuration is very simple, so that not only is very easy to manufacture but also inexpensive production.

As described above, the present invention is provided with an operation mechanism with a simple configuration on one side of the lid provided to cover the upper portion of the container body, and among the operation mechanisms of the lid formed to have softer physical properties along with the rotation and lifting of the cap. By the easy operation of pressing the central part of the upper surface at a certain pressure, the inside of the container becomes a vacuum and close sealing with the outside makes it possible to further improve the sealing force, and in particular, the structure is greatly simplified to reduce the manufacturing cost. Provides economic benefits
