Hanging plug type sealing and spring pushing type container sealing device and packaging container and application of hanging plug type sealing and spring pushing type container sealing device

Abstract

A container sealing device comprises a control moving cover part with a material cavity structure, a hanging plug component and a spring, the container sealing device is installed on a neck structure arranged at the top of a container or the bottom of the container to form a packaging container, before the packaging container is opened, the control moving cover part is rotated, under the action of the spring, a sealing plug of a hanging plug component and the material cavity structure of the control moving cover part longitudinally move, the sealing plug at the head end of the material cavity structure is further opened, materials in the material cavity structure can be released into the container, and the effects of closed storage and release blending of the materials are achieved. The container sealing device is provided with a positioning control structure, assembly and material filling of industrial production are easy, the structure is exquisite, the controllability is good, and accurate control and complete release of various types of materials can be achieved. The invention further provides components of the container sealing device, a material storage and release device and the packaging container and application of the container sealing device.

Description

technical field [0001] The present invention relates to the field of packaging containers for products, in particular to a container closing device and a packaging container comprising the closing device. It is a kind of packaging container that releases the sealed and sealed materials into the container to achieve the automatic mixing of various materials before opening the packaging container, or to achieve the function of automatic mixing and deployment. [0002] The packaging container can be widely used in the packaging of medicines, beverages, drinking wine, health food, formula food for special medical purposes, general food, medical equipment, sanitary products, cosmetics, daily necessities, etc., especially suitable for packaging containers containing liquid materials Hermetic packaging, storage and mixing of products. The invention also relates to the packaging composition of the packaging container, the assembly method of the closure device and its use. Backgroun...

Problems solved by technology

The existing technical solutions use two or more different packaging bottles/bags/boxes for independent packaging, and when they are used, they are recombined for use, which is easy to cause inconvenience in carrying, inconvenient use, and easy to cause secondary pollution, etc. unfavorable factors

[0005] International patent application WO2007/129116 and international patent application WO2012/175934 disclose a container closure device, which is provided with a fluid chamber in the cover member, and the opening of the fluid chamber is opened by lifting the transmission plug member through the housing, and then Introduce the contents of the cover member into the container; but the above-mentioned prior art or other prior art solutions have the following disadvantages: (1) The outlet of the material storage and release part is small, and it is impossible to realize the discharge of solid materials and viscous materials; It is difficult to release smoothly into the container, especially for amorphous bulk materials, larger solid materials or viscous materials; (2) The structure of the cover member can only be used to seal liquid materials, and the set It is difficult to realize the closure and release of solid materials by the plug member, and the fluid chamber needs to be pressurized to release the liquid materials; (3) The space in the neck of the container
