Container structure used for storing liquid

Abstract

The invention discloses a container structure used for storing liquid. The container structure comprises a container body. The container body is provided with a valve part through which the liquid is loaded or extruded. The container structure further comprises an inner obstruction composite bag, an inner container body, a sealing piece, a silicon oxide film layer and a glass fiber layer. The inner obstruction composite bag is connected with the valve part and provided with a containing chamber containing liquid. The inner container body is made of HDPE, and the silicon oxide film layer is arranged on the outer wall of the inner container body in a vacuum pasting manner. The glass fiber layer is wetted and mixed through epoxy resin, and then the glass fiber layer is pasted to the outer surface of the silicon oxide film layer. A sealed space for gas to be arranged is defined between the inner obstruction composite bag and the inner container body. The provided container structure used for storing liquid is simple in structure, reasonable in design and easy to achieve. The container structure is manufactured at low cost, gas obstruction and overall container strength enhancing can be guaranteed, and the quality guarantee period is prolonged.

Problems solved by technology

[0002] Drinks have become an integral part of life; existing drinks such as beer, containing CO 2 All carbonated beverages require containers for storage or transportation. At present, stainless steel barrels are the most widely used, but the production costs, transportation and recycling costs of stainless steel barrels are too high, and they need to be cleaned, sterilized and dried. The final sewage also has a certain impact on the environment, and at the same time affects the drinking taste; more importantly, the air in the stainless steel barrel cannot be completely replaced, and it is easy to mix some air during the filling and storage process, and the air dissolves in the beverage. Medium, affecting the shelf life and drinking taste of the drink;

[0003] In order to solve the problem of high cost, people use PET to make filling barrels. Although the filling barrels are lower in cost and do not need to be cleaned and recycled, their strength is much worse than that of stainless steel barrels. Due to beer, containing CO 2 The pressure generated by the filling of carbonated beverages is about 7 bar (or 7 kg), and the PET filling barrel is prone to explosion and other dangers under the high pressure of 7 bar (or 7 kg) due to the limitations of materials and processes; The shelf life of the drinks in the PET barrel is still only about 3 months;

[0004] Not only that, the existing way to press out the drink is to directly put CO 2 Pour it into the liquid and squeeze out the drink through gas pressure. This method not only easily squeezes and deforms the container body, but also easily affects the normal taste of the drink;

[0005] To sum up, the existing container structure still needs to be further improved. On the basis of reducing the cost, it can also ensure the quality of the beverage stored in it and prolong the shelf life of the beverage.
