Easy-to-open plastic bags

Abstract

To provide a plastic bag that is easy to open. [Solution] Non-slip areas 4, 5 are created by printing or applying non-slip ink, non-slip coating agent, non-slip top coat agent, or adhesive ink or adhesive to the outer surface of the front and back sides near the opening. By providing these non-slip areas, fingertips are less likely to slip, making it easier to open the plastic bag 1, which previously was difficult to open due to slippery fingertips.

Description

[Technical Field]

[0001] This invention relates to a plastic bag that eliminates the difficulty of opening by providing a non-slip area near the opening of the bag, which would otherwise be difficult to open due to slipping fingers. [Background technology]

[0002] Currently used plastic bags are made of a slippery material and are statically charged, causing the front and back sides to stick together, making them extremely difficult to open. The most common way to open such bags is to moisten your fingertips with water, and some supermarkets even stock dampened cloths. You may also see people moistening their fingertips with saliva when opening a plastic bag, but moistening your fingertips with saliva is not a hygienic idea.

[0004] Opening a plastic bag is a struggle for everyone, especially in the dry winter months, when static electricity often builds up and causes the front and back of the bag to stick together, making opening even more difficult. Devices designed to eliminate this difficulty are available on the market, and several inventions and devices related to devices designed to assist with opening have been filed. In addition, several inventions and devices have been filed for methods of modifying the plastic bag itself to make opening these extremely tedious bags easier. These applications confirm the difficulty of opening a plastic bag, and a solution to make opening plastic bags easier is eagerly awaited. This device aims to make opening these troublesome bags easier. [Means for solving the problem]

[0005] This device aims to solve the problem of plastic bags being difficult to open by providing a non-slip area near the opening, which can cause fingers to slip. The device provides a non-slip area on the outer surface of the front and back of the plastic bag near the top opening using two methods. The first method involves printing or applying a special non-slip ink (hereinafter referred to as "non-slip ink"), a non-slip coating (hereinafter referred to as "non-slip coating"), or a non-slip top coat (hereinafter referred to as "non-slip top coat") to create letters or graphics on the outer surface of the front and back of the plastic bag near the top opening. Areas coated with the non-slip ink, non-slip coating, or non-slip top coat have increased friction resistance, making them less slippery for fingers. The second method involves printing or applying a special sticky ink (hereinafter referred to as "adhesive ink") or a weak adhesive such as a releasable adhesive (hereinafter referred to as "adhesive") to create letters or graphics on the outer surface of the plastic bag near the opening. The areas where adhesive ink or adhesive is applied become sticky and non-slip. Using the above two methods, non-slip areas are created on the outer surface of the front and back sides near the opening of the plastic bag. [Effects of the Invention]

[0006] As described above, this device provides non-slip areas on the outer surface of the front and back sides of the plastic bag near the top opening. To open the bag, simply rub one non-slip area with your thumb and the other non-slip area with your fingers. This separates the front and back sides of the bag, which are tightly packed together around the top opening, allowing you to easily open the bag. There's no need to use a special tool to open the bag, and there's no need to moisten your fingertips. This plastic bag can be easily opened anytime, anywhere. [Brief explanation of the drawings]

[0007] [Figure 1] This is an oblique view of a plastic bag shaped like a shopping bag, with a non-slip area provided inside the binding edge. [Figure 2] This is an oblique view of a plastic bag shaped like a shopping bag, with the position of the non-slip part changed. [Figure 3] This is a perspective view of a vertically long rectangular plastic bag with a non-slip area near the top opening. [Figure 4] This is an oblique view of a vertically long rectangular plastic bag in which the position of the non-slip part has been changed. DETAILED DESCRIPTION OF THE INVENTION

[0008] For plastic bags shaped like shopping bags, a non-slip area is created by applying a graphic or letter of a size suitable for pressing with a fingertip to the top of the central binding edge. For vertically long rectangular plastic bags such as garbage bags, a non-slip area is created near the top edge of the top opening in the same manner as above. [Example]

[0009] In the case of plastic bags shaped like shopping bags, a non-slip area is provided near the top opening within the central binding edge as shown in Figures 1 and 2. It is also possible to provide a non-slip area on part of the handle. In the case of vertically rectangular plastic bags, a non-slip area is provided near the upper edge of the top opening as shown in Figures 3 and 4. When opening a plastic bag shaped like a shopping bag or a vertically rectangular plastic bag made in this way, the non-slip areas on the outer surfaces of the front and back sides can be pinched and rubbed between two fingers to easily open it.

Claims

[Claim 1] This plastic bag is characterized by having a non-slip area on the outer surface of the front and back sides near the upper edge of the opening including the binding edge in the case of plastic bags commonly known as shopping bags, which have handles on both upper ends and a binding edge in the center, and on the outer surface of the front and back sides near the upper opening in the case of vertically long rectangular plastic bags.
