Description

[Detailed description of the invention] "Industrial application field" This invention is a method for packaging food using synthetic resin film bags or paper bags, and when the bag is opened and the remaining food is put back into the bag. It is a device that can be sealed while the bag is inside, and the opening can be sealed when the bag is opened.

"Prior art and its problems" Conventionally, as a tool for opening bags made of synthetic resin film, a notch is provided in a flat plate having an arbitrary external shape, and a razor blade is inserted into the notch. There was one that was installed internally so that it was exposed at the corner of the bag, but the blade was pressed against the bag to cut it.In principle, the blade of the razor was pressed against the sealing piece of the bag. However, since the bag is made of a soft material with no stiffness as described above, there is no force to press in the direction of the cutting edge, and as a result, the sealing piece is not cut and remains in a loose state. There is a point.

The invention of Utility Model Application Publication No. 57-4910 only involves opening the sealing part of the bag, and unlike the present invention, it does not have the function of sealing the leftover food after opening the bag while leaving it in the bag. However, the purpose of the invention is completely different, and there are the following problems.

Because the blade cannot be replaced, no matter how good the other tools are, if the cutting edge of the blade wears out (it wears out after about a month of normal use), it becomes unusable.

In addition, the cutting method is to place the tip of the blade on one end of the sealing piece and press the tip along a fixed line to cut. If there is, it can be cut, but the thin vinyl bags and polyester bags that are the target of this invention have no stiffness but are strong against tension, so they cannot be cut when cut. There is a problem in that the blade does not cut the bag and becomes loose due to the lack of return force.

There are many cases where the contents of the bag are snack foods, etc., and you want to store the uneaten contents in the bag, but moisture can get in through the opening and make the snacks, snacks, etc. damp. The problem was that the product had a bad taste, and because the opening could not be sealed even if it was folded, it was an unsanitary condition that allowed moisture and insects to get in.

``Problems to be solved by the invention'' This invention can easily open bags containing snack foods and retard foods, which are made of thin synthetic resin films that are difficult to cut using normal cutting methods, and can be used for long-term use. The aim is to create a bag with a structure that allows the opening to be sealed so that the contents remain in the bag.

"Means for Solving the Problems" The present invention is an invention that achieves the above-mentioned purpose, and will be explained below with reference to the drawings.

FIG. 1 is a sectional view of essential parts showing an embodiment of the present invention. FIG. 2 is a perspective view showing an embodiment of the present invention.

The length of the sealing piece 5 of the bag body 4 that clamps the clamping face plates 2 and 3 of the clip body 1 which clamps pieces of paper etc. by installing a spring inside and pivoting the intermediate position of two opposing plates. One clamping face plate 2 is provided with a vertically long slot 6 in the longitudinal direction at the central position, and its peripheral edge 7 is gently inserted to allow the clamping face plate 2 to slide in the longitudinal direction. A blade piece with a protruding blade part 9 facing inward and blade edges 10 and 11 at both ends facing in the longitudinal direction is implanted in the shallow bottom of the recess 8 on the peripheral wall, and is screwed. The blade body sliding body 12 is tightened and fixed, and the inner surface of the clamping face plate 2 is provided with a needle-shaped protrusion 15 in the longitudinal direction at the center position of the front clamping face 13 and the rear clamping face 14, which are divided by the longitudinal slot 6.
A required number of elastic rubber or foam rubber tapes are provided on the inner surface of the other clamping face plate 3 at the position where the needle-like protrusions 15 that are in the clamping state contact with the opposing clamping face plate 2. This is a bag opening/sealing tool made by adhesively bonding the body 16.

"Operation" Since the present invention has the above-described structure, the sealing piece 5 of the bag body 4 is inserted between the clamping face plates 2 and 3, the planned cutting position is aligned with the longitudinal slot 6, and the spring of the clip body 1 is activated. The force closes the clamping face plates 2 and 3, and at the same time, the cutting edge 11 pierces the flat surface of the sealing piece 5,
The protrusions 15 on the inner surfaces of the clamping face plates 2 and 3 similarly pierce the periphery of the planned cutting line to cut the tape body 16.
When the blade body sliding body 12 is pinched with the fingertips and slid through the vertical slot 6, the blade portion 9 planted below is interlocked, and the blade edge 11 cuts the sealing piece 5. It is something.

When sealing the unsealed sealing piece 5, the clamping face plates 2 and 3 are opened and the opening is placed on the tape body 16, and the clamping face plates 2 and 3 are closed.

``Example'' The main body consisting of the clamping face plates 2, 3 and the clip body 1 can be integrally molded from synthetic resin, but it can also be molded from metal in the same way. It can be integrally molded from a certain synthetic resin. Although the tape body 16 and the needle-like protrusions 15 are generally complete in the present invention, they may be used in only one row.

When used at home, the length of the clamping face plates 2 and 3 will match the length of the bag 4 for snack foods, and when used for business, the length will match the length of the sealing piece 5 of each bag 4. It can be selected according to the length.

"Effect of ideas" The effects of the present invention are as follows.

(b) The bag body made of thin synthetic resin had no stiffness and was difficult to cut, but the blade tip 11 was inserted after applying tension around the planned cutting line with the needle-like protrusion 15 and tape body 16. The most ideal cutting method was realized.

(b) The bag body 4, which is tensioned and clamped, eliminates the flaws of the conventional cutting method, which caused it to flop and not cut.
This method takes advantage of the property of the material, which is strong against tension, but in a tensed state, it is brittle enough to escape if the cutting edge touches even a single point.

(c) Since the blade part 9 is a replaceable blade type, by replacing the blade part 9, which is subject to wear and tear, it can be used for a long period of time, and the blade always remains sharp.

(d) The present invention can be used with one hand, and the bag body 4 can be supported by the free hand, so unlike structures that require the use of both hands, the contents can be heavy. This prevents defects such as when the bag falls and the contents protrude from the bag.

(E) This invention has an opening function and an epoch-making function that can seal the opened opening to make it airtight, and the contents of the bag are not usually consumed at once. In most cases, it is left behind. The contents sealed in the bag are often items that do not like moisture in the air, items that will deteriorate quickly when exposed to air, items that do not allow dust in the air to enter, or items that may transfer other odors. I used to worry about how to easily and completely seal the package after opening it, such as for items that I don't like. However, with this invention, you can just pinch the opening with the clamping face plates 2 and 3 with a single touch. Since it can be sealed, it is hygienic and can always maintain its original good condition.
