Description

Vaccum container to preserve food

The present invention relates to a vacuum container for food preservation, and more particularly, to a vacuum container for food preservation so that the vacuum generating means is integrally provided on the lid of the container so that the vacuum state can be quickly brought into the inside of the container by an easy operation. It is about.

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

In addition, in the case of fermented food, the fermentation and ripening speed of the food proceeds too fast as the breeding of microorganisms is activated, which leads to poor preservation.

On the other hand, to delay the fermentation and decay of food is the key to blocking the outside air, and proposed for this is a closed container, that is, a vacuum container.

As such a vacuum container, a configuration such as registered utility model publication No. 280847 (name: vacuum sealing device of a container) and registered utility model publication No. 200997 (name: vacuum food storage container) have been proposed in Korea, but in these configurations, an internal structure is proposed. There is a lot of risk of loss because the vacuum formation of the weak or the vacuum forming means must be provided separately at all times.

In contrast, Japanese Patent Application Laid-Open No. 11-49243 (name: food preservation container) includes a first exhaust mechanism 2a and a first exhaust mechanism 2a which are opened and closed at the upper portion of the lid 2, as shown in FIG. The tubular fixing holding means 2b which protrudes the upper surface of the cover 2 upward by the predetermined diameter centering on the 1 valve 3 and the 1st exhaust opening 2a, and the outer peripheral surface of this fixing holding means 2b. A cap 4 provided to be able to slide up and down along a second side, a second exhaust port 4a through which the upper surface of the cap 4 is penetrated to a predetermined diameter, and for opening and closing the second exhaust port 4a from above. The structure which consists of the 2nd valve 5 was proposed.

In the above configuration, the fixed holding means 2b and the inner space of the cap 4 constitute the pump chamber 6, and the first valve 3 and the second valve 5 are operated by the vertical slide action of the cap 4. Are to be opened and closed in a direction corresponding to each other.

That is, when the cap 4 is raised, the pump chamber 6 is in a vacuum state and the second valve 5 is closed while the first valve 3 is opened, and predetermined air is pumped from the inside of the lid 2. Induced by (6).

When the cap 4 is lowered again, the second valve 5 is opened while the first valve 3 is closed, as opposed to the state of electricity, so that the air inside the pump chamber 6 is discharged to the outside.

As described above, when the lifting operation of the cap 4 is repeated several times, air is gradually discharged from the inside of the cover 2 so that the inside of the cover 2 is in a vacuum state.

When the cover 2 having such a function is combined with a predetermined container, the inside of the container 1 can be formed in a vacuum state, and thus the food deterioration or decay of the food can be further delayed while the food is stored therein. .

However, in the above-described conventional configuration, not only the manual slide operation of the cap 4 for vacuum formation is to be performed manually, but also when the vacuum force inside the cover 2 increases, particularly for moving the cap 4 upward. There is a disadvantage that the operation is difficult because the weight is further increased.

In addition, when the lowering operation of the cap 4 is provided with the second valve 5 is exposed to the upper surface of the cap 4 when the lowering operation of the cap 4 to open the second valve (5) There is a problem in that the handling of the cap 4 is not easy, such as being uncomfortable due to improper pressurization or interference with the action of the second valve 5.

Therefore, the present invention has been invented to solve the above-mentioned problems of the prior art, and the present invention allows the inside of the container to be quickly in a vacuum state by a piston action using a spring force, and at the same time reduces the operating force for vacuum formation. It is a main object to provide a food preservation container that allows for easy operation.

It is another object of the present invention to provide a container for food preservation that allows safer food storage.

Looking in more detail with respect to the operation of the present invention according to the configuration of each embodiment as follows.

11 and 12, the piston members 20 and 150 protruding to the upper portions of the lid members 10 and 110 by simply placing the lid members 10 and 110 on top of the container member 200 as shown in FIGS. 11 and 12. The lid member 10, 110 is firmly in close contact with the container member 200 by sucking air from the inside of the container member 200 by raising and lowering the inside of the container member 200 so as to be in a vacuum state.

To explain this in more detail, after receiving a certain amount of food in the container member 200, covering the lid members 10 and 110 and pressing the upper cap member 80 or the cap member 180 with the palm of FIG. 13. And the piston member 20, 150 is lowered as shown in Figure 14, wherein the first valve member 40, 120 is the upper surface of the lower cap member 30 or the lid of the first valve groove 112 While the inlet ports 31 and 113 are closed while being in close contact with the member 110, the second valve members 70 and 170 are finely moved upward from the upper surfaces of the piston members 20 and 150. Since the first exhaust port 21 or the exhaust port 152 is spaced apart to open, the air filled inside the piston members 20 and 150 is forced to the outside depending on the degree of descending of the piston members 20 and 150. Exhausted.

Subsequently, when the pressure holding the upper cap member 80 or the cap member 180 is removed, the piston members 20 and 150 are automatically raised by the elasticity of the spring members 60 and 140 therein. .

At this time, as the piston members 20 and 150 are raised, the first valve members 40 and 120 and the second valve members 70 and 170 act as opposed to when they are lowered. That is, as shown in FIGS. 15 and 16, when the piston members 20 and 150 are raised by the elastic force of the spring members 60 and 140, the volume of the inner space of the piston members 20 and 150 increases. The first valve members 40 and 120 are finely lifted to suck the air in the container member 200 through the inlets 31 and 113, and conversely, the second valve members 70 and 170. By closing the first exhaust port 21 or the exhaust port 152 formed on the upper surface of the piston member 20, 150, the air filled in the piston member 20, 150 is not discharged to the outside Block it.

As such, the present invention allows the piston members 20 and 150 to be lifted by removing the pressure to press or press the upper cap member 80 or the cap member 180 to slide air from the inside of the container member 200. The inside of the container member 200 is made into a vacuum state by repeating an operation of sucking the inside of the 11 or the guide groove 111 and discharging it to the outside again.

In other words, by forcibly discharging air from the inside of the container member 200 to the state of low pressure to keep the food contained therein to maintain the original state for a longer time to further extend the shelf life of the food will be.

On the other hand, as described above, it is most preferable that the piston members 20 and 150 are maintained in the lowered state as soon as possible after forming the inside of the container member 200 in a vacuum state. This is because the air in the interior of the sliding hole 11 or the guide groove 111 is completely discharged to the outside when the piston member 20, 150 is lowered, the sliding hole 11 or the guide groove 111 Inside is in a low pressure state. Therefore, if this state is maintained, it may flow into the sliding hole 11 or the guide groove 111 from the container member 200, but air does not flow back into the container member 200. Because.

When the food is stored in the container member 200 for a predetermined period of time, the container 1 may be hooked to the upper portion of the valve body 191 of the vacuum removing member 190 or the lifting shaft as shown in FIGS. 17 and 18. When the upper part of the upper part is caught and pulled upward, the air inlet 15 or the outside air inlet hole is in communication with the outside, and the outside air flows into the inside of the container member 200 at a lower pressure than the air to remove the vacuum. Let's go. When the vacuum is removed in this way, the lid members 10 and 110 can be easily separated from the container 200.

In the above-described configuration, in particular, when the container member 200 and the lid member 10, 110 is formed in a cylindrical shape, the lid is in contact with the upper end of the container member 200 as shown in FIG. The sealing groove 16 is recessed in the outer peripheral bottom surface of the member 10, 110 at least slightly larger than the thickness of the container 200, and the packing 17 is firmly inserted into the sealing groove 16. The packing 17 is coupled to the configuration in which the upper end of the container 200 is in close contact.

In addition, the lid member 10, 110 has an outer periphery is formed to be slightly larger than the outer diameter of the container 200, so that the outer end portion extends downward to a predetermined height to form a coupling end portion 18 and at the same time the coupling end portion 18 On the inner circumferential surface of the alignment protrusion 19 is formed to protrude toward the outer circumferential surface side of the container member 200 at regular intervals on the circumferential surface, while forming a predetermined gentle inclination angle from the top to the lower circumferential surface of the container member 200 facing this By forming the fastening protrusions 210 to protrude outward, the fitting protrusion 19 is slidably moved along the inclination angle of the fastening protrusions 210, and the lid members 10 and 110 are more firmly coupled to the container member 200. It can be done.

In addition, in the present invention, the upper surface of the upper cap member 80 or the upper surface of the separation preventing member 160, so that each of the outer peripheral portion of the moon and day indicating the storage time, respectively, the upper cap member 80 and At the outer circumferential end of the cap member 180, as shown in FIG. 20, a pair of pointers 210 indicating the storage moon and the day are formed to be movable along the outer circumferential surface so as to indicate the moon and the day using these. The initial storage date can be displayed.

As described above, the present invention allows the lid members 10 and 110 of the container member 200 to be easily sanitized by providing a configuration for generating a vacuum by simple screwing or assembling.

In addition, since the vacuum forming operation is very simple, anyone can use it easily, and in particular, since it is possible to form the vacuum pressure as quickly as necessary, it is very convenient to use.

In addition, according to the present invention, it is possible to continuously maintain a stable storage state even when handling and moving the container 200 in a vacuum storage state by making an operation for removing a vacuum pressure intentionally or not during storage using a vacuum.

On the other hand, while many matters have been described in detail in the above description, they should be construed as illustrative of various preferred embodiments rather than to limit the scope of the invention.

Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the technical spirit described in the claims.

As described above, the present invention is easy to manufacture because each component is combined by screwing together or simple assembly, and is very convenient to repair due to component loss, and the formation of the vacuum member lid member 10 (110) To be made by a pumping operation of elevating the piston members 20 and 150 at the upper part of the), and further reducing the operating force by reaction force using the spring members 60 and 140 to provide a very easy operation. do.

In addition, the present invention can form the required vacuum pressure faster, and the components for generating the vacuum pressure in proportion to the size of the container member 200 also, if the size is formed large, the time required for forming the vacuum pressure is almost similar. Since the operation force according to the size change of the container member 200 is also similar, in particular, there is an advantage that can be more stable and food storage for a long time.
