Container sealing device with hanging plug type sealing and releasing functions and packaging container and application thereof

Abstract

The invention discloses a container sealing device. The container sealing device comprises a control cover piece with a material cavity structure and a hanging plug component, the container sealing device is installed on a neck structure arranged at the top or the bottom of a container to form a packaging container, and before the packaging container is opened, through rotating the control cover piece, a sealing plug of the hanging plug component and the material cavity structure of the control cover piece are longitudinally displaced, the sealing plug arranged at the head end of the materialcavity structure is further opened, materials in the material cavity structure are released into the container, and the effects of closed storage and release blending of the materials are achieved. The material cavity structure is provided with a cylindrical material cavity structure or a capsule cavity structure with a macromolecular elastomer and a positioning control structure, accurate controland complete release of various types of materials can be achieved, and the material cavity structure is suitable for industrial production assembly and material filling, exquisite in structure and good in controllability. The invention further provides a packaging container composed of the container sealing device and a container and application.

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...

AI Technical Summary

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 is limited, which cannot meet the sealed storage of a large amount of materials, which limits its use range; (4) due to the existence of its specific plug member, after the contents are released, more contents will remain in the lid member, resulting in incomplete release of the contents; (5) the container closure is opened to allow the contents When the content is released into the container, the neck opening of the container is also opened at the same time, so that the sealing of the container is damaged at the same time, which cannot meet the requirements that the contents still need to be sealed after mixing and the mixture should be further disposed of; (6) using the mixture In this case, the entire container closure device needs to be removed from the neck of the container, which is not conducive to the repeated use of the packaging container after rotation and unsealing, and also makes the inner core structure of the container closure device exposed to the outside of the container, which is easy to cause the mixture in the container to leak. Cross-contamination or accidental contamination; (7) It is difficult to release materials from the bottom of the container upwards, which cannot meet the diversified choices of container and product production; (8) It is difficult to realize the anti-theft opening function of the closure device when it is twisted
