Description

Packaging container for separate storage

Technical Field

The utility model belongs to the technical field of packaging, and particularly relates to a packaging container for separate storage, which is suitable for storing various substances, such as medicines, cosmetics, chemical preparations and the like, and is especially suitable for storing cosmetics, wherein the cosmetics can be skin care substances such as liquid, solid, powder and the like.

Background

In the packaging technical field, two materials are often required to be mixed for use. However, the mixture is sometimes unstable, so that in a non-use state, the two materials need to be stored separately in a sealed manner; when in use, the two materials are mixed so as to achieve the purpose of current preparation and use. The materials may include medicines, chemicals, skin care products or cosmetics, etc. Conventionally, when the two kinds of materials are used as the mixture, the user needs to open the sealing parts of the two packing bottles respectively, then pour the materials in one packing bottle into the other packing bottle to mix, and the operation steps of mixing are complicated, so that the use burden is increased for the user. With the development of skin care product technology, some solid skin care products need to be stored in a sealed mode (such as freeze-dried powder), the solid skin care products cannot be contacted with air before being mixed with other substances, otherwise, due effects are lost, the solid skin care products are mixed with other liquid skin care products when used, and the freeze-dried powder cannot be contacted with air in the mixing process. This is particularly important.

For this purpose, a chinese patent No. ZL202222319060.2 (bulletin No. CN 218537457U) discloses a packaging container and a hybrid packaging bottle adapted to the packaging container, which is a packaging container structure specifically for such skin care products, comprising a container portion having a first container cavity for containing a first medium, a connecting member and a push rod, and an opening of the first container cavity is provided with a pierceable sealing barrier. The push rod is movably arranged at the end part of the connecting piece and used for puncturing the sealing barrier. The connecting piece is operatively cup jointed in the holding part and is promoted towards holding part direction, makes sealed separation piece be pierced by the push rod, and holding part and then drive the push rod and move towards the direction of keeping away from holding part, realizes switching on of first holding chamber. Through setting up packaging container and locating packaging container's extrusion part to form two confined chamber that hold respectively, the user only need with the direction promotion of holding part towards the push rod, drive the push rod motion can make first chamber that holds and second hold the chamber and switch on the mixture of realizing two kinds of materials, improve the convenient degree that the material mixes.

The aforementioned patent suffers from the following drawbacks:

1. the push rod has the functions of puncturing and inner plug, so that the material adopted by the push rod is softer, the hardness of the punctured part on the push rod is lower, and the sealing film is not easy to puncture; the cutting edge of the puncture part is positioned at one side, and only one puncture opening is arranged when the sealing film is punctured, so that the liquid medium in the packaging container provided with the push rod is not easy to flow out.

2. Because the push rod has the functions of puncturing and the inner plug, in the process of screwing the accommodating part into the packaging container, the push rod can be pushed open firstly and then the sealing film can be punctured, and when a user is operating, the packaging container can be inverted (namely the opening end of the packaging container faces downwards), the sealing film can flow out of the packaging container, the sealing film is not punctured, and the flowing medium cannot enter the first accommodating cavity to be mixed with substances in the first accommodating cavity immediately, and flows out of the accommodating part to cause waste.

3. The body portion material of holding portion is glass, inconvenient direct setting sealing membrane, so threaded connection has the port support on the extension of body portion, port support and holding portion's opening part are equipped with the sealing washer, port support's mouth end is equipped with sealing membrane seal, during the use, place in the holding portion and be solid or powder material, it is higher to the vacuum requirement, therefore before mixing with the solution material in the packaging container, need pack good sealedly (stop holding portion material contact air), but the consumer has the mistake to open port support when using, lead to the inside material to become invalid.

In view of the above, the packaging container disclosed in the foregoing patent document can be further improved.
