When I bought a lunch box at a supermarket or convenience store, I put it in a plastic bag and brought it home, but there was a problem that the contents of the lunch box were tilted on the way and the contents became uneven and the juice spilled out.

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 A passage portion communicating with the outside of the body is provided, and is pressed against the mouth of the bag inserted from the passage portion to bend one piece, and the mouth of the bag is locked by the one piece; The opening of the bag is closed not by the structure sandwiching the side surface of the bag but by the force with which one part is bent and the bag is elastically restored. In a bag with low frictional resistance, such as a shopping bag, when the bag is shaken, the one piece is curved, so that the locking tool is likely to move upward, and the contents 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.

Further, in Patent Document 4, the number of slits is as small as 4 or less, and if any one of them is detached, there is a fear that it becomes unstable and tilts. Also, when removing the bag from the locking tool, it is difficult to remove the bag due to the hook-shaped portion at the tip of the slit. In addition, the tip of one part between the slits is arcuate, but if the bag is large, the side of the bag cannot enter the slit, and there will be an extra bag side part in the through hole. It is difficult to smoothly discharge the air inside the bag to the outside by the side portion of the bag. It simply closes the mouth of the bag. If a large bag is dealt with by enlarging the through hole, it is necessary to enlarge the locking tool. A small bag is more expensive than necessary and is uneconomical. Further, since the R-shaped portion at the tip of the protruding portion between the slits is wide, when the bag side surface is inserted into the slit, the resistance increases and it is difficult for the bag to enter smoothly.

The present invention solves the above-described problems, and aims to provide a locking tool that can be easily attached to and removed from 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 approximately the center of the distal end portion and the base end portion of the slit toward the base end portion, and the plurality of slits are centered on the center portion of the through hole The angle formed by the tip of any one of the slits and the tip of a slit adjacent to the given slit is less than 90 degrees, and the material of the flat plate is resin.

Further, the number of the slits is 5 to 8.

Further, the dimension of the flat plate is a dimension within a postcard size.

The slits are provided symmetrically about the center of the through hole.

In addition, a passage from the outside of the main body to the through-hole, which is a passage through which a bag to be locked can pass, is provided.

The present invention is a locking device in which a through hole is provided near the center of a flat plate and a plurality of radial slits are provided from the center of the through hole toward the outer periphery. Insert the opening of the plastic bag into the squeeze through hole, hold the plastic bag with one hand, and push down the latch 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, since the base end portions of the plurality of slits extending radially from the through holes are formed wide, if the bag side cannot enter the slit with a large bag, the excess bag side surface has a wide base end portion. By accumulating in the portion, there is room in the bag opening portion of the through hole portion, and air can be discharged smoothly. Moreover, since it is not necessary to enlarge a through-hole even if it is a big bag, it is not necessary to enlarge a locking tool, and it can be set as a compact locking tool irrespective of the size of a bag. Further, when the locking tool is pushed down, the side portion of the shopping bag is smoothly sandwiched between the slits. 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 holding the side surface of the shopping bag with the slits at a plurality of positions, it is possible to prevent the locking tool from further moving and to maintain the stopped state. This stabilizes the contents in the bag and does not tilt even if the bag shakes. Moreover, even if a part of the plastic bag sandwiched between the slits is removed due to the large number of slits, the state is maintained by holding the other part. The number of slits is preferably up to about 8. If the number of slits is large, the strength of the protruding portion between the slits becomes weak.

Further, in the case of a flat plate having high elasticity, the through hole is pushed wide and the mouth of the shopping bag is inserted. 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.

In the case of a flat plate having rigidity, the bag can be smoothly inserted into the through hole by providing a passage through which the bag can pass from the outside of the flat plate.
