A multifunctional liquid packaging bag

technical field

The utility model belongs to the packaging field and relates to a multifunctional liquid packaging bag.

Background technique

With the development of packaging technology, the improvement of living standards, and the improvement of environmental protection and safety awareness, liquid packaging bags are widely used in various fields, such as packaging for juice, milk, mineral water, soy sauce, medical reagents, liquid fertilizers, etc. There are also various forms and materials of packaging bags, such as Tetra Pak, pillow bags, stand-up bags, etc.

At present, the pure water used in homes and offices is mostly in the form of barrels. When using it, it must be placed on the water dispenser or use a water press to discharge water. The pure water barrels are reused many times. After recycling, they need to be disinfected. high.

Cold brew tea and cold brew coffee are becoming more and more popular as a new way of life. The so-called cold brewing tea is to brew tea leaves with cold water, which is a method of making tea that subverts the tradition. Compared with making tea with hot water, brewing tea with cold water has a more mellow and sweet taste, reduces the release of tea tannins, reduces bitterness and astringency when drinking, and increases the taste of tea; it can reduce the caffeine content of tea soup and slow down the effect on the stomach. Those with sensitive constitution or weak stomach are suitable for drinking; in addition, brewing tea with cold water can almost completely release the essence of the tea, and the tolerance is very large, there is no risk of astringent taste after brewing, which can be a good tea for hot summer For a refreshing choice with a difference. Especially when traveling or when hot water cannot be boiled, as long as there is drinkable cold water such as purified water or mineral water, you can drink tea. Whether you are an office worker, driver, or mountain climber, you only need to bring some mineral water, you can put the tea in it, and after several hours of static brewing, you can enjoy delicious and healthy cold brew tea. Of course, those who like to drink hot drinks can also pour out cold brewed tea and drink it after proper heating.

Cold brew coffee is cold coffee made by soaking coffee powder in cold water for several hours. It is different from iced coffee that is brewed in hot water and then frozen or added with ice cubes. Caffeine, less bitterness, extra flavor.

However, due to the long time required for cold brewing tea and cold brewing coffee, the volume of ordinary brewing utensils is small, and only a few mouthfuls of brewing once can be finished, and it will take a long time to brew again, which affects the quality of cold brewing tea and cold brewing. The promotion of new lifestyles such as making coffee.
