Problems solved by technology
Obviously, there are many disadvantages in the structure of the sealing port formed by this process: firstly, the process is complicated, requires a lot of equipment, the production cost is high, and it is not easy to operate manually; After entering the accessory cover, the residual gas or redundant liquid between the liquid and the accessory cover will be compressed. Even if the sealing process is completed, the internal pressure will not be released, which will cause excessive internal pressure and cause hidden dangers. ; Again, although the bonding force of glass glue is strong, it is not suitable for common materials, and once the external light and heat environment changes, it is easy to deteriorate the glass glue and make the sealing effect worse

The invention discloses a structure for sealing an opening of a liquid container. The structure comprises a container main body with the opening and an accessory sealing cover, wherein the accessory sealing cover covers the opening of the container main body, and a main sealing ring is arranged between the accessory sealing cover and the opening; and the accessory sealing cover is also provided with an air outlet and an accessory air plug for blocking the air outlet. The invention also discloses the corresponding assembly method. The assembly method comprises the following steps of: (1) sleeving the main sealing ring on the accessory sealing cover, so that the main sealing ring cannot loosen, and an accessory sealing cover assembly is assembled; (2) pressing the accessory sealing cover assembly into the opening of the container main body, so that the main sealing ring is positioned between the opening of the container main body and the accessory sealing cover; and (3) plugging the air outlet by the accessory air plug. According to the structure, the edge at the periphery of the opening is sealed by the main sealing ring, and compressed air / liquid which is generated because the accessory sealing cover is pressed into the liquid container can be discharged from the air outlet, so that a phenomenon that inner pressure accumulates is avoided, and the structure is suitable for packaging the opening of the liquid container.
Description
technical field [0001] The invention relates to a sealing port of a container, in particular to a sealing port structure of a liquid container. Background technique [0002] The sealing technology of the liquid container opening has always been the focus in the packaging and processing industry. The sealing process of liquid containers is different from ordinary solid-state packaging because the contents are liquid, but has its own unique process requirements. Present general liquid container opening sealing means, is to adopt accessory capping+sealing ring+glass glue to realize. Specifically, the liquid is first poured into the main body of the container, and then the accessory cover with the sealing ring is pressed into the container opening, and the elastic deformation characteristics of the parts are used to withstand each part, and then the accessory cover and the container are quickly connected. Glue the joints of the openings to seal. Obviously, there are many disa...
