Abstract

A roll-type plastic bag stand is prepared in which the opening of a plastic bag cut from the roll-type plastic bag stand can be easily opened regardless of the season, age, or physical condition. [Solution] When a plastic bag from a roll-type plastic bag is sandwiched between rubber sheet magnets and the tip is pulled, the free electrons of the conductor plate move and the front and back of the plastic bag are negatively charged, and the repulsive force makes it easy to open the opening of the plastic bag. At the same time, by pulling the tip, wrinkles containing air inside the plastic bag are generated, and the electrostatic force between the sheets on the front and back sides of the plastic bag weakens, making it easier to open the opening of the plastic bag.

Description

The present invention relates to a roll-type plastic bag stand.

When trying to put products in plastic bags outside the checkout counters of supermarkets and convenience stores, especially in winter, we often see elderly people unable to open the opening of the plastic bag due to static electricity. There are wet towels, etc., but I don't feel like touching them because of the season.

A roll-type plastic bag stand is prepared in which the opening of a plastic bag cut from the roll-type plastic bag stand can be easily opened regardless of the season, age or physical condition.

On the inside of each upper and lower conductor plate, prepare a member with a PVC support sheet attached to the back side of the rubber sheet magnet, and from above, the upper conductor plate, the upper PVC support sheet, and the upper A rubber sheet magnet, a plastic bag from a roll type plastic bag, a lower rubber sheet magnet, a lower PVC support sheet, and a lower conductor plate are arranged in this order,
A pair of magnets composed of the conductor plate, the PVC support sheet, and the rubber sheet magnet
The laminate is used as a cradle for a roll-type plastic bag of a roll-type plastic bag stand, and the plastic bag is
The tip of the plastic bag from the roll-type plastic bag is sandwiched between the pair of laminates.
is pulled , positive static electricity is generated by friction between the bottom side of the roll-type plastic bag and the surface of the upper conductor plate, and free electrons are in contact with the opposite surface of the upper conductor plate. It moves to the surface of the supporting sheet and is transmitted to the upper rubber sheet magnet by contact electrification of static electricity. Negative static electricity is generated by friction between the rubber sheet magnets at the bottom and the plastic bag surfaces at the top and bottom, and the repulsive force makes it easier to open the opening of the plastic bag . At the same time, pick and pull with fingers that are easily charged positively,
The negatively charged plastic bag attracts and makes it easier to open the opening of the plastic bag.

By using the present invention, the opening of a plastic bag cut from a roll-type plastic bag stand can be easily opened regardless of the season, age or physical condition.

FIG. 1 is a cross-sectional view of the side of a conventional roll-type plastic bag stand, in which a rubber sheet magnet and a conductor are attached to generate electrostatic induction in order to suppress electrification. FIG. 2 is a detailed side cross-sectional view of the electrostatic induction generating portion described in FIG. FIG. 3 is a top view of the state when the plastic bag is started to be pulled out. FIG. 4 is a top view of the state when the plastic bag has been pulled out. FIG. 5 is a diagram showing the state of the opening when the plastic bag is cut from the main body of the plastic bag stand. FIG. 6 is a photographic image of the real thing of FIG. FIG. 7 is a photographic image of the opening in its normal state.

An embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG.

Claims (1)

Inside the upper and lower conductor plates, a member with a PVC support sheet pasted on the back side of the rubber sheet magnet is prepared above and below.
Upper rubber sheet magnet, poly bag from roll poly bag, lower rubber sheet magnet,
A lower PVC support sheet and a lower conductor plate are arranged in this order, and the conductor plate,
A pair of laminated bodies composed of the PVC support sheet and the rubber sheet magnet are rolled
A plastic bag stand is used as a support for a roll-type plastic bag, and the plastic bag is attached to the pair of laminates.
When the tip of the plastic bag from the roll plastic bag is pulled while sandwiching it , positive static electricity is generated by friction between the lower side of the roll plastic bag and the surface of the upper conductor plate, and free electrons are transferred to the upper conductor. It moves from the opposite surface of the plate to the surface of the upper PVC support sheet that is in contact with it, and is transmitted to the upper rubber sheet magnet by contact electrification of static electricity . When the bag is pinched and the tip of the plastic bag is pulled with fingers, negative static electricity is generated by friction between the upper and lower rubber sheet magnets and the surfaces of the upper and lower plastic bags, and the repulsive force opens the opening of the plastic bag. At the same time, by pinching and pulling the tip of the plastic bag with fingers that tend to be positively charged, the negatively charged plastic bag is attracted and the opening of the plastic bag becomes easy to open. A roll type that uses both static electricity and magnetism. poly bag stand.
