When I bought a lunch at a supermarket or convenience store, I put it in a plastic bag and brought it home.

However, the locking device of Patent Document 1 is configured by a sheet-like frame, and a convex piece formed by cutting is arranged at the center of the frame, and the center of the frame and the frame It has a structure in which a passage portion communicating with the outside of the body is provided, a piece portion is bent by being pressed by the mouth of the bag inserted from the passage portion, and the mouth portion of the bag is locked by the piece portion. This is simply to close the opening of the bag. For bags with low frictional resistance, such as plastic bags, when the bag is shaken, the one piece is curved, so that the locking tool can be moved upwards easily. May move and tilt in the bag. Further, the notch is for bending one part.

Further, the bag sealing device of Patent Document 2 is provided with a ring-shaped frame body and a flexible projecting toward the inner side of the frame body, and the bag mouth when the bag mouth is inserted through the frame body. And a flexible piece that bends and seals the bag mouth. Similar to Document 1, there is a risk that the flexible piece will bend and the sealing tool will move upward and the contents will move and tilt in the bag.

In addition, the mesh bag mouthpiece of Patent Document 3 is gathered on a flat plate with its tips directed toward the center, and several arrowheads that are warped upward are arranged in a circle to form a central hole, from the entrance to the center It has a structure that has a passage that leads to the hole of the mouthpiece, and the tip of the mouthpiece's arrowhead is squeezed so that the mouthpiece does not move into the mesh eye. With a small number of bags, the fasteners may move and the contents may move and tilt in the bag. In addition, the bag may be torn at the tip of the arrowhead.

The present invention is intended to solve the above-described problems and to provide a locking tool that can be easily attached to a bag such as a shopping bag and prevents the contents of the bag from being inclined.

In order to solve the above-mentioned problems, the present invention provides a locking tool for locking an opening of a bag from the outside, wherein a through hole is formed in a main body formed of a flat plate, and extends radially from the through hole. A plurality of existing slits are formed, and the slits are formed to be wide from the center of the leading end and the base end of the slits toward the base end. A notch is provided at the periphery .

The shape of the tip of the protrusion formed between the slits is R-shaped.

A passage extending from the outside of the main body to the through hole and having a passage through which a bag to be locked can pass is provided.

In the present invention, a through hole is provided near the center of a rigid flat plate, a plurality of radial slits are provided from the center of the through hole toward the outer periphery, and a passage portion in which the through hole communicates with the outer peripheral edge of the flat plate is provided. It is a fastener. The opening of the shopping bag is inserted into the through-hole through the passage part from the notch part of the throttle passage part, and the holding part of the shopping bag is held with one hand, and the locking tool is pushed downward with the other hand. When the locking tool is pushed down, the air in the plastic bag is released to the outside so that the locking tool can be brought into close contact with the plastic bag smoothly, and the contents of the plastic bag handle containing the contents The vertical position of the center of gravity of the shopping bag containing the object can be set. This keeps the contents of the shopping bag always horizontal.

In addition, the base ends of the plurality of slits extending radially from the through holes are formed wide and the tips of the protrusions formed between the slits are formed in an R shape, and the flat plate has rigidity. Since the protrusion between the slits is not easily deformed by being provided, the side portion of the shopping bag is smoothly sandwiched between the slits when the locking tool is pushed down. Further, when the plastic bag is held and the plastic bag is lowered, the side of the plastic bag further bites into the slit due to the opening of the plastic bag due to the weight of the contents. The side part of the shopping bag is sandwiched between the slits to prevent the locking tool from moving upward. Further, by supporting the side surface of the shopping bag with the slits at a plurality of positions, the locking tool becomes more difficult to move, the contents are stabilized in the bag, and the bag does not tilt even if the bag shakes.

Moreover, there is no possibility that a bag will be torn by making the front-end | tip of the protrusion part formed between the slits into R shape.

In addition, when the material of the locking tool is a material that can be torn off by hand such as paper, the closing tool can be easily removed from the shopping bag by tearing between the slit and the notch by hand. In this case, the locking tool is disposable.

Further, in the case of a flat plate rich in elasticity, a passage is not necessarily required because the opening of the plastic bag can be inserted by expanding the through hole. In addition, by making the flat plate a material having friction resistance, the flat plate back and the plastic bag are in close contact with each other, the flat plate is difficult to move, the contents are more stable, and the bag does not tilt even if it shakes.
