Abstract
Description
Technical Field
[0001] The utility model relates to a double-mouth composite barrel in the technical field of storage and transportation container packaging. Background Art
[0002] In the transportation of materials, barrel containers are often used as packaging and storage containers, especially for the storage and transportation of liquid materials. In order to avoid the contamination of the packaging container by the material and reduce the cleaning and use costs of the container, the current measure of setting an inner bag in the packaging container is adopted to isolate the material from the inner wall of the packaging container. By replacing the isolation inner bag, the packaging container can be reused many times, which can effectively reduce the packaging cost of the material. Since the container barrel is mostly an integrated structure, the container injection port is a single injection port, and it will bring certain difficulties to the placement of the liner bag for containers with multiple injection ports. Summary of the invention
[0003] The utility model aims at the deficiencies of the prior art and provides a composite barrel with double injection ports, wherein a barrel body and a barrel cover combined installation structure is provided, and an inner liner bag can be directly installed and fixed on the barrel cover outside the barrel body.
[0004] The utility model is realized by the following technical solutions:
[0005] A double-mouth composite barrel, comprising an outer barrel body, an outer barrel top cover, a flexible inner bag and a composite barrel connector, wherein the outer barrel top cover is buckled on the outer barrel body through a clamp, and the flexible inner bag is located in the outer barrel body, and is characterized in that: the composite barrel is an open barrel provided with a flexible inner bag, the outer barrel top cover is provided with double holes, the connector of the composite barrel is designed as a double interface, and a cross bar is used to form a conjoined structure, the double interface of the composite barrel connector corresponds to the double hole of the outer barrel top cover, and the composite barrel connector is fixed to the outer barrel cover through the nut of the composite barrel connector, and an annular heat sealing cover is provided at the bottom of each interface of the composite barrel connector, and the annular heat sealing cover is connected to the top film of the flexible inner bag by heat welding The composite barrel connector is connected, and the interface of the composite barrel connector becomes the bag mouth of the flexible inner bag; the above technical scheme is further explained: the outer barrel body and the outer barrel top cover of the composite barrel are made of solid hard materials; the above technical scheme is further explained: a sealing barrel plug is provided on the interface of the composite barrel connector; the above technical scheme is further explained: the opening of the composite barrel top cover is a flanged opening; the above technical scheme is further explained: the flexible inner bag of the composite barrel can be configured as a bag top film + an open bag, the composite barrel connector is heat-sealed and welded to the bag top film, and the diameter of the bag top film is larger than the outer barrel top cover; the bag body of the open bag is buckled on the barrel mouth of the outer barrel by turning it outward.
[0006] The utility model has the characteristics of convenient installation of the inner liner bag, expansion of the application function of the barrel body and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
