In industries such as daily chemical products, medicines, and foods, containers for containing liquid or semi-liquid products are usually equipped with product dispensers such as press pumps and nozzles to dispense the liquid or semi-liquid products in the container. In the process of dispensing the product, as the product in the container decreases, negative pressure will be generated in the container, which will cause the container to shrink and make it difficult to dispense the product. In order to solve the problem of container shrinkage, a balancing air hole or a balancing channel will be set on the product dispenser, so that when the product is dispensed outside the container, the air outside the container can be replenished into the container, which can prevent the container from being sucked out.

However, there are some problems with this method of replenishing air. One of these problems is that the air replenished into the container is the air from the surrounding environment, which may contain microorganisms such as bacteria and viruses. These microorganisms will come into contact with the liquid or semi-liquid product in the container and multiply in large numbers, which will have a negative impact on the characteristics of the product. In order to inhibit the growth of microorganisms, additives such as preservatives and antibacterial agents are added to the product. However, these additives can irritate human skin or mucous membranes, cause discomfort to the body, and even damage the skin and other body organs.
