Description

[Technical Field]

[0001] This invention relates to a plastic bag opener used to manually open the openings of plastic bags provided in supermarkets and the like. [Background technology]

[0002] After purchasing food at a supermarket, etc., when you go to the counter (sucker counter) and try to put some of the food into a plastic bag, it is often the case that the opening of the plastic bag sticks together due to static electricity, making it difficult to open. For this reason, people are currently forced to twist the opening of the plastic bag with their fingertips, rub it with both hands, or moisten their fingertips, which is effective in opening the bag, by spitting on them, or by placing their fingertips on a damp cloth placed near the plastic bag holder or on a float in a water container. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-65615 [Patent Document 2] Japanese Patent Application Publication No. 2024-62458 [Patent Document 3] Utility Model Registration No. 3249218 Summary of the Invention [Problem to be solved by the invention]

[0004] As mentioned above, in order to effectively open the opening of a plastic bag, some people have no choice but to use a damp cloth placed near the plastic bag holder or place their fingertips on a float in a water container, but many people refrain from using these methods for hygiene reasons, and as a result, it takes time to put purchased food and other items into plastic bags at the counter (sucker stand), which causes congestion in the area and slows down the flow of people. Furthermore, plastic bag openers such as those shown in Patent Documents 1 and 2 have been publicly known, and more recently, a method of opening plastic bags using the adhesive power of cellophane tape has been proposed, as shown in Patent Document 3.
