Description

Technical Field

[0001] The utility model relates to the technical field of container bottles, in particular to a double-tube packaging container. Background Art

[0002] With the increasing emphasis on skin care and maintenance by women, a variety of skin care products have emerged on the market. These products often require different packaging containers for storage, resulting in a large amount of desktop space being occupied, and it is time-consuming and laborious to find specific products during use. Therefore, there has also appeared a packaging container on the market that can centrally store multiple skin care products, keep the desktop tidy at the same time, and is convenient to use.

[0003] Refer to a double-tube hand cream bottle disclosed in a Chinese utility model patent with a patent application number of CN202020435474.X. It includes an inner tube body and an outer tube body. The inner tube body is arranged inside the outer tube body. The tops of the inner tube body and the outer tube body are both hermetically and fixedly connected through a sealing body. The bottom surface of the outer tube body is bonded with a PVC plastic hard layer. The bottom surface of the left side of the inner tube body and at the first liquid outlet is bonded with a first liquid outlet pipe. The other end of the first liquid outlet pipe communicates with the second liquid outlet and extends to the outside of the outer tube body. The second liquid outlet pipe is bonded at the third liquid outlet. In this utility model, by providing an inner tube body and an outer tube body, different textures of materials can be respectively injected into the inner tube body and the outer tube body. Moreover, by correspondingly using the first liquid outlet pipe and the second liquid outlet pipe, the two materials can be extruded simultaneously or separately, and the use performance is greatly improved.

[0004] However, in the above structure, the design of using a double liquid outlet pipe requires two sets of bottle caps to be screwed and closed. In this way, when using, two bottle caps need to be unscrewed separately. When wanting to use alternately, the other liquid outlet pipe needs to be screwed and closed, otherwise the materials in the two bottles will pour out together, affecting the use. Therefore, the design of using a double liquid outlet pipe will not only increase the difficulty of use and be troublesome to use, but also the bottle caps are easy to lose; moreover, the double liquid outlet pipe design will also affect the aesthetics of the bottle.
