Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spoilage prevention device, and more particularly to a spoilage prevention device that prevents oxidation and spoilage of the articles by creating a negative pressure state close to a vacuum inside a storage section in which articles are stored.

Traditionally goods, especially fresh foods, fruits and vegetables.

Products that are easily oxidized have been prevented from oxidizing or rotting by various means.

One method was to vacuum bank items. With this vacuum bag method, oxidation and spoilage can be prevented because the product is placed in a negative pressure state close to a vacuum.

However, this vacuum puncturing method not only requires large equipment, but also has the disadvantage that it is unsuitable for bagging a large number of items due to its unspecified shape.

Therefore, the present invention was created with the aim of providing a rot prevention device that can be easily used at home or in restaurants, etc., and can be used regardless of the shape of the stored article.

In order to achieve the above-mentioned object, the present invention provides a storage valve in a sealable storage part, a connection part in the storage valve, and a communication valve provided in the negative pressure source with an atmospheric valve. A specific embodiment of the present invention will be described below with reference to the illustrated example, in which a pipe is connected to the communicating pipe, and the connecting portion is detachably formed on the communicating pipe. - FIG. 1 is a schematic diagram of the present invention, in which the storage section 20 of the article 10
and a negative pressure device 30.

The storage section 20 includes a box 21 with a bottom, an opening/closing section 22 that can be sealed to the box 21, and a storage valve 23 and a connecting section 24 that protrude from the box 21 to the outside.

The negative pressure device 30 has a vacuum chamber 32 provided with a pressure gauge 31, one of which is connected to a negative pressure source 34 via a main valve 33, and the other connected to a communication vibrator 36 via a negative pressure valve 35. Also, the outside air vibe 3 is connected to this communication vibe 36 via an atmospheric valve 37.
8 is connected, and a connection port 39 is provided at the tip of the connection port 39 to which the connection portion 24 of the storage portion 20 can be freely attached and detached. Note that as the negative pressure source 34, a vacuum pump, an exhaust pump, or the like is used.

Next, the operation and operation of this embodiment will be explained.

First, the opening/closing part 22 of the storage part 20 is opened, and the desired article 10 is stored inside the box body 21. Thereafter, the opening/closing part 22 is closed to bring the box body 21 and the opening/closing part 22 into a sealed state.

Next, the connection part 24 of the storage part 20 is connected to the connection port 39 of the negative pressure device 30, and the negative pressure valve 35, the atmospheric valve 37, and the storage valve 2 are connected.
Close 3. Thereafter, the main valve 33 is opened and the negative pressure source 34 is operated to reduce the pressure inside the vacuum chamber 32 to a predetermined pressure.

After the inside of the vacuum chamber 32 reaches a predetermined pressure by the pressure gauge 31,
While closing the main valve 33, the negative pressure valve 38. The storage valve 23 is opened to bring the inside of the storage section 20 into a negative pressure state.

At this time, if the pressure inside the storage section 20 does not drop to a predetermined pressure, it is also possible to open the main valve 33 and operate the negative pressure source 34 to further reduce the pressure.

After the inside of the storage portion 20 is brought to a predetermined pressure in this manner, the negative pressure valve 38. The storage valve 24 is closed and the atmospheric valve 37 is opened. Then, the inside of the communication vibrator 36 becomes atmospheric pressure while the inside of the storage section 20 remains at 9 pressure. In this state, the connection part 24 is removed from the connection port 39, and the storage part 20 is stored in a negative pressure state.

If there are other articles 10 to be stored, those articles 1
0 is stored in another storage section 20 and the same operation is repeated.

When the article 10 is stored in the storage section 20 under negative pressure in this manner, the oxygen concentration inside is low, so that the article 10 can be prevented from oxidation and spoilage.

Also, in this embodiment, the case where the vacuum chamber 32 and the main valve 33 are attached has been explained, but even if these are not provided, the negative pressure source 34 can be used.
can be used by connecting directly to the negative pressure valve 38.

FIG. 2 shows an example in which a pressure gauge 25 is attached to the storage section 20.

This is convenient because the pressure inside the storage section 20 can be known from the outside of the storage section 20.

Further, FIG. 3 shows an example in which a flexible bag body 26 is used as the storage section 20.

Note that at this time, a closing part 27 is required to airtightly close the opening of the bag body 26.

In this way, articles can be stored in a manner similar to conventional vacuum banks.

As described above, the present invention can not only be easily used in restaurants and the like, but also can be used in a wide range of applications regardless of the shape of the stored article.
