Description

[Detailed description of the invention] The present invention relates to a bag sealing device, and more specifically to a bag sealing device consisting of a base material having a receiving groove and a fitting material that tightly fits into the receiving groove of the base material. The objective is not only to maintain the sealed state after the bag has been sealed, but also to develop a sealing tool that can be used to easily and efficiently perform bag sealing work, especially when sealing work for vacuum packaging. It is on offer.

Conventionally, various devices have been used to seal bags, and there are two types of sealing degrees.

One is to seal the bag with something such as a stapler, rubber ring, string, etc., and the airtight state is such that the flow of gas at the sealing part is not a big concern. The sealing is performed by bonding with an adhesive, heat sealing, etc., and is in a sealed state in which gas is blocked from the sealing portion.

Apart from the former, in the case of the latter, the bag must be torn in order to take out the items inside, and a torn bag cannot of course be used again.

Therefore, when attached to a bag, the gas flow in the sealing part is blocked, and in order to take out the contents of the bag, the sealing device shown in Figure 1 can be removed without damaging the bag at all. A seal is used.

This sealing device consists of a base material 2 having a receiving groove 1 and a fitting material 3. The base material 2 is made of hard synthetic resin, and the fitting material 3 is also made of hard synthetic resin like the base material 2. However, the base material 2 is slightly softer than the fitting material 3.

The fitting material 3 is shaped and sized to fit into the receiving groove 1.

To use this sealing tool, insert one end of the bag into the receiving groove 1 of the base material 2.
Further, the bag is placed on top of the base material 2 by placing the fitting material 3 on top of the receiving groove 1, and then firmly pressing the fitting material 3 to fit it into the receiving groove 1. The bag is fitted and sealed in the receiving groove 1 between the bag and the fitting material 3, and the fitting material 3 can be taken out from the receiving groove 1 in order to take out the items inside the bag.

When using this method, the sealing operation is easy, the airtightness is sufficient, and the bag has the advantage of being able to be used many times, but since the fitting material 3 is made of a hard material, some parts of the bag are It has the disadvantage that it cannot be properly sealed.

This partial sealing of the bag is explained by referring to FIG. 2 when, for example, clothes are vacuum packed using a vacuum cleaner at home. With one end of this bag 4 placed on the base material 2, the air suction tube 6 of a vacuum cleaner is inserted into the bag 4 to suck and discharge air to reduce the pressure, and when the desired level is reached. , pull out the air suction tube 6, and then insert the fitting material 3 into the receiving groove 1 on the bag.
Place the fitting material 3 on the receiving groove 1 by pressing it firmly.
At this time, the air suction tube 6 is pulled out and the fitting material 3 is placed on top of the bag.
If it takes some time to firmly press the fitting material 3, outside air will enter the inside of the bag that has been depressurized during that time, but with the above-mentioned hard fitting material, one part of the bag is sealed off. That's not possible.

In other words, most of the other part Y, except for the part X where the air suction tube 6 is inserted, cannot be sealed off during the air suction operation, and only after the air suction tube is withdrawn after the air suction is completed, can X be closed. It is possible to seal both parts with Y.

This invention was developed after intensive study and various experiments in order to create a sealing device that can seal off only the necessary parts when necessary. A base material with a JIS hardness of 60°
The purpose can be well achieved by using a bag sealing device made of synthetic rubber or synthetic resin with a hardness in the range of ~98° and a fitting material that fits tightly into the receiving groove of the base material. The present invention was obtained.

In the present invention, the receiving groove 1 is made of a hard synthetic resin such as epoxy resin or ABS resin.

This receiving groove 1 is normally provided in the base material 2, but in this case, the receiving groove 1 and the base material 2 are made of the same material.

The feature of the present invention lies in the fitting material 3, which is made of synthetic rubber or synthetic resin with a JIS hardness in the range of 60° to 98°. For example, in the other major part Y of the bag 4 in FIG.
The part of the fitting material 3 that spans the X can become independent from the receiving groove 1 and allow the air suction tube 6 to be inserted through it.In this way, only the X part of the bag can be decompressed. Sometimes the air suction tube 6 is left unsealed, so after pulling out the air suction tube 6, the fitting material 3, which is freestanding at a small portion X, is laid down and fitted into the receiving groove 1. Therefore, it is extremely rare for air to flow back into the bag from this part, and there is almost no concern that the decompression effect will be diminished.

In addition, what is shown in FIG. 4 is one in which a notch 7 is provided in the fitting material 3, and when the fitting material 3 is made to stand on its own from this notch 7, the fitting material 3 can more easily stand on its own.

In addition, after sealing the bag with the sealing tool in this way,
When storing this bag, in order to prevent the mating material 3 from accidentally coming off, a ring or a cap should be fitted onto the base material (while the mating material 3 is still mated). This is desirable.

The base material having the receiving groove used in the present invention is preferably made of a hard synthetic resin such as epoxy resin or ABS resin, and the fitting material has a JIS hardness of 60.
It is made of synthetic rubber or synthetic resin in the range of 98° to 98°, but for example, polyurethane resin, polyester elastomer, synthetic comb, EVA, soft vinyl chloride, etc. are preferably used, and the shape of this fitting material is It can be of any shape, such as round or square, as long as it fits tightly into the receiving groove.

Bags using the sealing device of the present invention may be made of any material, but especially bags used for vacuum packaging or when gas barrier properties are specially required for moisture-proofing purposes. It is best to use a bag made of a compatible material, or a bag made by laminating aluminum foil, aluminum vapor-deposited film, etc. and a synthetic resin film.If a higher oxygen barrier property is required, an oxygen-removing bag may be used. You can also put the medicine in a bag.

Since the present invention is constructed as described in detail above, the fitting material can be bent at any angle at any position along its length, so that a part of the bag opening, for example, an air suction tube, can be bent at any position along its length. Leaving only the width for entry and exit, most of the other part is fitted into the receiving groove, and this part is used as a sealed part. After the air suction operation is completed, the bent fitting material is laid down and inserted into the receiving groove. This makes it possible to easily seal the entire surface of the bag mouth while maintaining a desirable vacuum state inside the bag.This operation is suitable for women and children who are inexperienced in handling the bag. This is an extremely excellent idea that has made it possible to easily perform vacuum packaging at home, which was previously thought to be possible only for professionals.
