Description

Material storage and release device and component parts and application thereof

Technical Field

The invention relates to the field of product packaging containers, in particular to a material storing and releasing device capable of sealing, storing and releasing materials, which can be generally applied to a container closing device.

The material storage and release device can be widely applied to the packaging of products such as medicines, drinks, drinking wine, health-care foods, special medical formula foods, common foods, medical instruments, sanitary products, cosmetics, daily necessities and the like, and is particularly suitable for the application of a sealing device of a container containing liquid materials in the container. The invention also relates to a component of the material storing and releasing device, an assembling method of the material storing and releasing device and application of the material storing and releasing device.

Background

In many applications, such as mixed packaging of different materials, it is very necessary to discharge or release and mix each material into another material shortly before using a mixture of the various materials. Storing the product in a pre-mixed form is often not possible or desirable because when the product is stored as a mixture for a period of time, it can undesirably react with each other or cause the mixture to degrade. Common examples are e.g. two or more pharmaceutical components which have better stability and longer shelf life when not mixed than when mixed.

Of course, other liquids, liquids and solids, mixtures of liquids and liquids, such as water, alcoholic beverages, other solvents or solutions, and oily liquids, and the like, may also be used. For products such as drinks, drinking wine, health foods, formula foods for special medical purposes, common foods, medicines, medical instruments, sanitary products, cosmetics or daily necessities, two or more different substances or materials in the products need to be stored separately within the shelf life of the products, so that the products are more beneficial to the stability, freshness, function guarantee or improvement of other quality aspects. The prior technical scheme adopts two or more different packaging bottles/bags/boxes to carry out independent packaging, and the packaging bottles/bags/boxes are recombined to be used when in use, so that the carrying inconvenience, the use inconvenience, the secondary pollution easily and other adverse factors are easily caused.

International patent application WO2007/129116 and international patent application WO2012/175934 disclose a container closure device in which a fluid chamber is provided in a lid member, and a stopper member is driven by lifting of a housing to open an opening of the fluid chamber, thereby introducing the contents in the lid member into a container; however, the above prior art or other prior art solutions have the following disadvantages: (1) the outlet of the material storage and release part is small, so that smooth release of solid materials and viscous materials cannot be realized, and particularly amorphous massive materials, large solid materials or viscous materials are difficult to release into a container smoothly; (2) the structure of the cover member is only used for sealing the liquid material, the sealing and releasing of the solid material by the arranged plug member are difficult to realize, and the liquid material can be released only by pressurizing the fluid chamber; (3) the space of the neck of the container is limited, which cannot meet the sealing storage of a large amount of materials and limits the application range of the container; (4) due to the existence of the specific plug member, after the content is released, more content remains in the cover member, so that the content is incompletely released; (5) when the container closing device is opened to release the content in the container, the neck opening of the container is also opened at the same time, so that the sealing performance of the container is damaged at the same time, and the requirement that the content still needs to be sealed after being mixed and the mixture is further treated cannot be met; (6) when the mixture is used, the whole container closing device needs to be taken down from the neck of the container, which is not beneficial to the repeated use of the packaging container in the rotary unsealing process, and also leads the inner core structure of the container closing device to be exposed outside the container, thus being easy to cause the cross contamination or the accidental contamination of the mixture in the container; (7) the situation that materials are released upwards from the bottom of the container is difficult to realize, and diversified choices of the container and product production cannot be met; (8) it is difficult to achieve the anti-tamper opening function of the closure when twisted.
