Description

Technical Field

[0001] This utility model relates to the field of supermarket shopping technology, and in particular to an auxiliary device for switching packaging materials for different products. Background Technology

[0002] In supermarkets, you often see staff skillfully using plastic bags and other packaging products to pack various goods. This seemingly ordinary action actually carries many important meanings. The use of plastic bags is especially important for fresh food. Fresh vegetables are neatly stacked in plastic bags, which helps retain their moisture, preventing them from wilting too quickly and allowing customers to take them home in good condition. It also makes them easy for customers to carry without worrying about juices staining other places. The same applies to fruit; packaging it in plastic bags not only makes weighing and pricing easier but also helps prevent it from being crushed or deformed. Loose snacks and candies, when placed in small plastic bags, become easy to handle and store, while also ensuring food hygiene. Plastic bags and other packaging products have become powerful "helpers" in supermarkets, ensuring the integrity of goods and facilitating customer shopping. Although they may seem ordinary, they play an irreplaceable role.

[0003] However, different products do require different packaging materials, such as plastic bags of various sizes and plastic takeout boxes of various dimensions. Fresh produce may be suitable for thick plastic bags with some preservation function, while cooked food is often more suitable for plastic takeout boxes. However, if these packaged products are displayed separately in supermarkets, far apart from each other, customers will have to search back and forth to find their takeout after checkout, which is extremely inconvenient, affects the overall shopping experience, and reduces checkout and takeout efficiency. To address this technical problem, this application proposes an auxiliary device for switching packaging materials for different products. Utility Model Content
