DETAILED DESCRIPTION

[0016] The following is a further description of the contents of the utility model in conjunction with the accompanying drawings:

[0017] As shown in the figure, a combined connector is an interface part used to connect and fix the liner bag mouth and the container injection port. The interface part is installed on the container mouth. The combined interface part is composed of parts A, B and C. Part A is a tube structure. The outer flange under part A is connected to the liner bag mouth by heat sealing. Part B is a through-core structure. The top is provided with an outer flange and a sealing gasket, and the bottom is provided with a bottom hook, which is connected to the upper part of part B through an extension leg. Part B forms a whole with parts A and B through snap-fit ​​or threaded fitting. A sealing groove and a sealing ring are provided on the outer wall of the tube body of part A, and it is sealed and connected to part B through the sealing groove and the sealing ring; part C is the entrance and exit of the interface part, which is snap-fitted to the outer wall of part A through multiple sealing rings, and the upper flange of part C is sleeved and fixed on the container mouth. The combination of parts A, B and C forms the discharge port of the liner bag.

[0018] The combined structural design allows components A, B and C to be combined first during the production process of the liner bag, and then the large flange of component A is heat-sealed to the liner bag, so that the combined interface component and the liner bag form a whole.

[0019] The above is a description of the technical solution of the present invention. Those skilled in the art may modify the technical solution described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; these modifications or replacements are within the spirit and scope of the technical solutions of the embodiments of the present invention.
