Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is a method for sealing granular materials such as rice, coffee, etc., solid materials, and applying a vacuum sealing material to the air remaining inside a packaging bag, packaging container, etc. This invention relates to a sealed vacuum packaging method and device.

BACKGROUND OF THE INVENTION Conventionally, conventional plastic bags for rice, etc. are sealed with air still in them, which causes the quality of the rice to deteriorate.To prevent this, there are vacuum-packaged bags for rice, etc.

The conventional vacuum packaging procedure for rice will be explained using the 12th section.

(1) Wrinkle the rice and pack it into a packaging bag.

(2) Open the packaging bag (2), hold the opening with a rod-shaped member @ to prevent the rice from spilling out, and lay it down on a horizontal table.
To arrange packaging bags in a flat state on a table and to stack a large number of bags so that they can be stored and transported.

(3) Air release tube of the vacuum pump from the opening of the packaging bag □
Insert □□ into the bag to remove any air remaining in the bag and empty it into a vacuum. 〇(4) The mouth of the vacuumed bag is sealed using a sealing device using high frequency, etc., and then closed and packaged. .

Problems to be Solved by the Invention In the above-mentioned vacuum packaging, if the packaging bag is placed upright and vacuum is applied across the 7'C, the bag becomes distorted and cannot be flattened afterwards.

Conventionally, a packaging bag filled with rice is folded horizontally to form a flat shape as described above, but when the bag is folded horizontally, the rice spills out of the opening, so the opening is held down with a rod-shaped member and the bag is folded horizontally. Moreover, it is difficult and time consuming to remove air from the opening and close the opening while the bag is horizontal and closed. It takes a lot of time to air out and seal the openings, but it takes a lot of time to match the work speed, which makes the work less efficient.In addition, the air suction device using the vacuum bong 1 and the openings are sealed by fusing the openings with high frequency waves. Vacuum packaging of rice is not popular because the sealing device 2 must be installed at the same location, and the structure of the air suction device and sealing device is complicated and expensive.

This invention involves punching an air vent hole with a punch in a packaging bag that has been sealed in a conventional manner, and then placing an air vent tube in close contact with the air vent hole to remove all the air remaining in the bag. To provide a seal-type vacuum packaging method and its apparatus in which vacuum is created, the air vent hole is sealed with a sticker hJl+5, and vacuum packaging is quickly carried out in a simple manner.

8 Means for Solving the Problems This invention is a companion to solving the above-mentioned problems, and as a specific invention, it uses an appropriate punching tool (4) to form air vent holes smaller in diameter than grains of rice, etc. or more complex. (2) A process of providing a packaging container etc. containing US prisoners etc. with a hole, and using an appropriate suction and pasting device connected to the vacuum bong 1, air is drawn into the packaging bag (1) through the air vent hole (2).

(5) is an air vent cylinder, a vacuum bong 7 (Pi) is connected to the rear glyph 1 (9J), and a large number of air passages (6) are bored on the upper circumferential surface of the cylinder (5). Prepare the piston (7) for its own weight when moving back and forth, and temporarily hold the sealing material (3) on the front side of the piston (7) by leaving a ventilation passage (eaJ) around the area to suck in air from the bag. The piston (7) in the example is arranged in the center to match the inner diameter of the cylindrical body, and there is a vent hole (6a) for removing air from the seven bags of ventilation passages around the piston (7), and the inner The air passage 2 sealing material (3) is a vent hole (6bJ) for sucking air, but the piston is not limited to this.For example, the outer diameter of the piston (7) is made smaller than the cylinder (5) and A ventilation passage may be provided between the piston (7) and the cylinder body, and a ventilation hole for sucking the sealing material may be provided in the piston (7).

The above-mentioned sealing material (3) is a thin paper/plastic bag sealing material if the rice bag is a plastic bag, or a plate-shaped sealing material made of A&A when the rice bag is a packaging container, etc. is the adhesive surface (8a) to the bag.

In the above example, is there a seal material on the piston? Although we have shown the case where the sealing material is temporarily held by suction with air, it is also possible to temporarily hold the sealing material on the piston using magnetic force.

In order, the surface or the entire surface of the vinyl was made into a magnetic rod, and one side of the sealing material was coated with iron powder to hold the magnetic layer.

In the embodiment, as a structure for moving the piston (7) forward and backward, a spring Qf) is interposed between the piston (7) and the cylinder (5) to always urge the piston in the fftU direction, and the shaft (Il) of the piston (7)

Next, the process of enclosing rice and vacuuming the tomo packaging bag will be explained.

The first step is to fill a plastic packaging bag with the measured amount of rice as shown in Figure 1, close the mouth to allow air to enter, and seal the packaging bag (1) as shown in Figure 2. Lay it on its side and place it on a horizontal stand, and then insert the punching tool (4) all the way through the surface of the bag and/or make a plurality of air vent holes (2) (see Figure 3, No. 6). Stack the bags to make them flat.

In the second step, open the on-off valve with the operation button Cl73 of the grill section (9), apply suction using the vacuum bong 1, and apply the sticker material (3)' on the front surface of the piston (7). hold,
Press the lower part of the operating lever 04 and gear the upper part backwards to retreat against the stop member μsl seven-shot αQ, and then move the shaft (

The suction action of the vacuum pump removes the air inside the bag through the air vent hole (2), the front space, and the ventilation hole around the piston (7).
61aJt- to vacuum the bag and release the pressure on the operating lever) to advance the piston (7) fully forward with the elastic force of the spring αQ. The sticker material (3) temporarily held on the front surface of the piston is pressed and adhered to the air vent hole (2) of the packaging bag (1) for vacuum packaging.

In addition, when advancing into the piston (7)', the adhesive sealing material (3) should extend fltx so that it is flush with or slightly protrudes from the surface of the front opening of the cylinder (5). Further, although the sealing type vacuum packaging apparatus of the embodiment is of a portable type so that it can be held in the hand to perform vacuum packaging operations, the present invention is not limited to this.

According to the sealed vacuum packaging method and device of the present invention, there are a step of making an air vent hole in the bag with a punching tool, and removing the air remaining inside the bag by hitting the air vent hole on the air vent cylinder and pulling out the air remaining inside the bag with a vacuum bong 1. Since vacuum packaging can be accomplished by a simple operation of extruding the sealing material using a piston and pasting it into the air vent hole to close it, the work efficiency can be significantly improved.

Furthermore, according to this method, the packaging bag is placed upright, filled with rice, etc., and then the air-filled bag is sealed and then laid down on its side, so the rice does not spill out and the air vent hole can be inserted into the horizontal bag. The bag can be easily shaped into a flat shape.

The diameter of the air vent holes made in the refill is smaller than the size of the rice grains, etc., so the rice, etc. will not flow out when suctioned by the vacuum bomb (only one air will be forced out), so the diameter of the air vent hole is smaller than the size of the rice grains, etc. If the number is large, air can be suctioned quickly.

If the vacuum packaging device is small and portable as in the example, it will take up less space, be easy to move, and be convenient to use. It can be provided to the safe f#i.

Not only bags of rice, but also containers that contain coffee, containers that contain coffee, etc., can also be used with air vent holes in the lids, and a sealing material for air circulation is attached to the lids. For packaging purposes, or when a sealed container is fully opened and some of the contents are used before the lid is closed, an air vent hole is provided in the lid and vacuum sealing is repeated to maintain the freshness of the contents, such as coffee and seaweed. .
