Description

Container closure with angled snap and detent catch and components therefor

Technical Field

The utility model relates to a packaging container field of product specifically is to relate to a container closing device with slope form buckle, through the mutual rotation of slope form buckle, makes container closing device realize sealed and release function, the utility model discloses component, packaging container, the packing composition of this container closing device are still provided.

It should be noted that the container closing device is a device which can be installed at the neck opening of the container, seal the neck opening of the container to close the container to form a packaging container, and contain materials, and the materials contained in the container are released into the container and mixed with the materials in the container by operating the container closing device, so as to achieve the effect of mixing and blending the contents when a consumer is about to use the container.

The container closing device and the packaging container thereof can be widely applied to the packaging of products such as medicines, drinks, drinking wine, health-care foods, formula foods for special medical purposes, common foods, medical instruments, sanitary products, cosmetics, daily necessities and the like, and are particularly suitable for the sealed packaging, storage and mixed blending of the products containing liquid materials in the packaging container.

Background

In many applications, such as mixed packaging of different materials, it is very necessary to release each material into another material shortly before the mixture of the various materials is used. Storing the products in a pre-mixed form is often not possible or desirable because when the products are stored as a mixture for a period of time, they may 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 the

In the shelf life of mixed liquid products, such as drinks, liquid medicines, homogenate meals for special medical formula foods, liquid cosmetics, liquid reagents and the like, two or more different materials in the products need to be stored separately, 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 WO2010/101389 discloses a container cap composed of an inner cap and an outer cap, which are assembled together by a screw thread between the inner cap and the outer cap, so that a material is sealed in the container cap, and the container cap is mounted at a neck of a bottle; in use, the contents of the container cap are released into the bottle by opening the container cap in stages. However, the prior art solution has at least the following disadvantages:

(1) the reliability of the sealing is poor. When the container cover is opened, the outer cover is lifted relative to the inner cover, the extension part 23a of the second cylindrical part is separated from the annular groove 12b, so that the sealing performance between the outer cover and the inner cover is damaged, the inner cover and the outer cover are in a mutually rotatable state, and when the container is shaken to mix materials, the mixed materials in the bottle body can be leaked to the outside of the bottle body, which is not beneficial to the use and carrying of products.

(2) The matching property with the existing industrialized fittings is poor, and the production matching with the existing industrialized products is not facilitated. The thread at the bottle mouth part needs to be specially made and matched with the inner cover, a bottle blank needed by the bottle needs to be prepared independently, the extra cost of the product is increased, the improvement of the production efficiency is not facilitated, and meanwhile, the existing and industrialized production filling equipment cannot be utilized, so that the industrial production is hindered.

(3) The convenience and experience of use are poor. After the material in the container lid released to the bottle, still being in the state that can rotate each other between inner cup and the enclosing cover, the consumer need twist the enclosing cover with different effort when using, and the stage of twisting is many moreover, has influenced the convenience and the experience of using and has felt.

(4) When the materials are released, the outer cover and the inner cover generate a lifting effect, and the matching performance and the original aesthetic property of the outer cover and the container are damaged.

(5) The convenience of use is poor. When the container cover is opened, the sealing acting force between the outer cover and the inner cover needs to be overcome, and meanwhile, the skirt structure of the outer cover needs to be overcome, a larger acting force needs to be kept between the inner cover and the bottleneck to enable the inner cover and the bottleneck to be relatively fixed and not to rotate, so that the manual operation of a user is not easy, the whole container cover is separated from the neck of the container, and the material in the container cover is not released.
