Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a simple vacuum evacuation device, and in particular to a vacuum evacuation device for evacuation of air inside a pressure-resistant container such as glass or plastic for preserving foodstuffs and the like. This invention relates to a device for vacuum evacuation.

(Prior Art) Vacuum packaging, in which food is packaged by removing air from the inside of a container containing food, is widely used to preserve food and the like.

However, for example, when preserving vegetables, fruits, seafood, cooked foods, etc. in households, it is normal to store them in appropriate containers and store them at room temperature, refrigerate, or freeze them. In such cases, if the air inside the container is expelled and the food is stored in a vacuum state, the storage condition of the food product will be significantly improved, and its taste and flavor can also be maintained.

However, there has never been a simple vacuum evacuation device used for this purpose.

(Problems to be Solved by the Invention) This invention has been proposed taking these points into consideration, and aims to provide a simple vacuum evacuation device that can be used extremely easily. be.

Another object of the present invention is to provide an exhaust system for vacuum packaging that can be carried out using glass, plastic, or other storage containers that are widely used in general households.

Furthermore, the present invention aims to provide a vacuum evacuation device that enables continuous and repeated use of vacuum packaging, opening, and vacuum packaging.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a device for easily exhausting air in a pressure-resistant container in which an object such as food is stored, which It consists of a lid member that seals the opening of the container, a main body equipped with a vacuum pump, and a suction head connected to the vacuum pump of the main body by a suction hose. a lid body formed with a concave surface portion having a hole; a thin top seal piece that can be accommodated in the concave surface portion of the lid body and is itself flexible; and a container opening fixed to the back surface of the lid body. The suction head has an air intake port that communicates with the suction hose and a deaeration port that can be opened and closed, and a lower part of the suction head that is in close contact with the surface of the lid body. It is characterized by having a suction chamber with a head gasket.

(Function) According to the device of the present invention, the lid body is first placed over the opening edge of a pressure-resistant container such as a glass container containing an object such as food so that the lid packing member comes into contact with the opening edge. Then, the top seal piece is placed on the concave surface of the lid, and the suction head is set so as to surround the concave surface. Next, by operating the vacuum pump on the main body and holding the suction head slightly pressed against the lid, the air inside the container is rapidly exhausted from the inlet of the suction chamber, creating a vacuum state. The upper seal piece, which is housed in the concave portion of the lid and closes the through hole, floats up in the concave portion as a result of vacuum suction, thereby opening the through hole.

The vacuum pump is stopped when the vacuum pressure within the container reaches the appropriate pressure.

Then, the deaeration plug of the suction head is loosened to release the adsorption state of the suction head to the lid. At this time, a pressure difference occurs between the inside of the container and the outside air, and the upper seal piece of the concave portion of the lid is strongly attracted to the through hole, thereby tightly closing and sealing the through hole.

This completes the vacuum packaging, and the food and the like in the container is preserved in this state.

When taking out food etc. inside the container, peel off the top seal piece with your fingers and then open the lid. Repackaging after removal of the article is done in exactly the same way as above.

(Example) The present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 is an overall perspective view of a vacuum packaging device as an embodiment of the inventive device, partially seen through, and Fig. 2
The figure is a cross-sectional view of the main part showing the vacuum suction state, and FIG. 3 is a perspective view showing the state in which the top seal piece of the lid member of the vacuum-packed container is peeled off to open the container.

As shown in FIG. 1, the simple vacuum evacuation packaging apparatus of the present invention includes a lid member 10 that seals an opening 8 of a pressure-resistant container 9 containing food, etc., and a main body 20 that is equipped with a vacuum pump 21. and a suction head 30 connected by a vacuum pump 21 of the main body 20 and a suction hose 22.

The term "pressure-resistant container" here refers to a container that does not undergo extreme deformation during evacuation, such as a bag-like container, and is generally considered to be a container made of glass or plastic. It is being

As understood from the cross-sectional views of FIGS. 1 and 2, the lid member 10 includes a top seal piece 11 and a lid body 1.
2 and a lid packing member 19.
The upper seal piece 11 is made of a flexible material such as rubber or plastic, and has a diameter of about 30 mm and a thickness of about 2 mm.
It is a thin piece of about mm size.

The lid body 12 is made of a plastic molded product,
A concave portion 13 for accommodating the upper seal piece 11 is formed at the center of the front side, and a through hole 14 is bored approximately at the center of the concave portion 13 .

The lid packing member 19 is made of an elastic material such as rubber or plastic, and is sandwiched between a flange 18 extending from the outer periphery of the lid 12 to the back surface in an L-shaped cross section, as shown in FIG. 2, for example. The opening edge 8a of the container to be packaged is brought into close contact with the opening edge 8a. The thickness of the lid packing member 19 is desirably about 2 mm in order to absorb the unevenness of the opening edge 8a of the container.

The main body 20 is equipped with a conventionally known reciprocating (piston type) vacuum pump 21 as shown, for example, and is operated by a switch 26. In FIG. 1, reference numeral 21a indicates an inlet port of the vacuum pump 21, and 21b
22 is an intake hose, 23 is an exhaust hose, 24 is an exhaust section provided on the back of the main body, 25 is a vacuum pump motor section, and 27 is a display section that displays the suction pressure of the vacuum pump. .

As can be better understood from the sectional view of FIG. 2, the suction head 30 has a suction chamber 31 in close contact with the top surface of the lid 12 for suctioning and exhausting the air inside the container 9.

That is, the suction chamber 31 has an intake port 32 that communicates with the intake hose 22 and a deaeration port 33 that can be opened and closed, and is provided with a head packing 39 in close contact with the top surface of the lid 12 at its lower part.
The intake port 32 is a cylindrical portion 3 protruding into the chamber 31.
2a. Reference numeral 32b is the notch. The deaeration port 33 is always sealed by a gasket 36 of the deaeration plug 35 via the cylindrical portion 33a. By rotating and loosening the degassing plug 35, a slight gap is formed between the gasket 36 and the edge of the cylindrical portion 33a, and air enters through the degassing port 33, degassing the inside of the suction chamber 31. As a result, the adsorption state of the suction head 30 to the lid 12 is released.

Next, this inventive device will be described in more detail along with its operating sequence.

FIG. 2 shows a state in which a glass container 9, for example, containing food to be preserved is vacuum packed. The body 12 is placed. Then, the upper seal member 11 is placed on the concave surface 13 of the lid 12, and the suction head 30 is set so as to surround the concave surface 13.

Next, by turning on the switch 26 of the main body 20 to operate the vacuum pump 21 and holding the suction head 30 slightly pressed against the lid 12, the air inside the container 9 will be rapidly drawn out from the intake port 32 of the suction chamber. It is evacuated and a vacuum is created. Note that the through hole 14 is accommodated in the concave portion 13 of the lid body 12.
The upper seal piece 11 that closes the through hole 1 rises as shown in the figure as a result of vacuum suction and closes the through hole 1.
Open 4.

The vacuum pressure inside the container 9 can be detected by the suction pressure displayed on the display section 27 installed in the main body, and when a suitable pressure is reached, the vacuum pump 21 is stopped automatically or manually. Ru.

Then, the deaeration plug 35 of the suction head 31 is rotated to release the adsorption state of the suction head to the lid 12. At this time, a pressure difference occurs between the inside of the container 9 and the outside air, and the upper seal piece 11 of the concave surface part 13 of the lid body 12 is strongly attracted to the through hole 14, and as a result, the through hole 14 is tightly closed. Seal. Vacuum packaging is now completed, and the food, etc. in the container is preserved in this state.

FIG. 3 is a perspective view showing the unsealed state of this vacuum-packed container.
This is done by peeling off the top seal piece 11 as shown in the figure. Since the top seal piece 11 is made of a thin and flexible material, it can be easily peeled off with the force of a human finger. If necessary, a knob protrusion 11A may be provided protrudingly as shown in the upper part of the figure.

(Effects) As can be easily understood from the above explanation, in the vacuum evacuation device of the present invention, the packaging
It can be used continuously and repeatedly by opening and repackaging, and for example, it is easy to take out food that has been temporarily stored and vacuum-storage it again, making it particularly convenient for cooking and preserving in general households.

Further, as containers for vacuum packaging, almost any container that does not undergo deformation due to suction can be used as is, and there is no need for complications such as refilling, making it extremely easy to use.

Of course, since the packaged food is stored in a vacuum state, the preservation state is greatly improved, and the fresh taste and flavor can be maintained for a long period of time. The benefits and benefits it brings are enormous.
