Technical Field
[0001] The utility model relates to the field of cosmetic packaging, and more specifically, to a cosmetic packaging bottle. Background Art
[0002] Packaging bottles are widely used in the cosmetics field. Their main function is to prevent cosmetics from being contaminated by the external environment. Among them, press-type packaging bottles are one of the most common packaging bottles in our daily life. Users only need to press lightly to get the right amount of cosmetics, without worrying about using too much or too little, making it convenient to take cosmetics.
[0003] The press-type packaging bottle includes a bottle body and a press pump threadedly connected to the bottle body. A pump head tube is fixedly connected to the bottom of the press pump. When the user presses the press pump, the pump head tube draws cosmetics through the suction port at the lower end thereof and sprays the cosmetics from the nozzle position of the press pump. However, there is a gap between the existing pump head tube and the inner bottom surface of the bottle body, which makes it difficult to completely suck out the cosmetics in the bottle body, resulting in a large amount of cosmetics residue in the bottle body. Moreover, after the cosmetics are used up, the entire packaging is discarded and cannot be recycled.
[0004] Therefore, new solutions are needed to solve these problems. Utility Model Content

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a cosmetic packaging bottle, comprising a bottle body and a press pump threadedly connected to the bottle body, a deformable inner liner provided in the bottle body, the inner liner being detachably connected to the press pump, a pump head tube located in the inner liner being fixedly connected at the lower end of the press pump, the pump head tube being a hard tube, a plurality of guide grooves communicating with the bottom surface of the pump head tube being provided on the outer peripheral wall thereof, and a suction port being provided at the bottom of all the guide grooves.
[0007] The utility model is further configured as follows: a hard head is provided at the upper end of the inner liner, a detachable threaded sleeve is provided on the hard head, a mounting ring is fixedly connected to the press pump, and an inner circumferential wall of the mounting ring is provided with an internal thread for cooperating with the threaded sleeve.
[0008] The present invention is further configured such that when the threaded sleeve is threadedly connected to the mounting ring, the lower end of the threaded sleeve is exposed outside the pressing pump.
[0009] The utility model is further configured as follows: the threaded sleeve comprises two splicing sleeves, the splicing sleeves are provided with a convex column and an embedding groove, and the convex column is used to embed into the embedding groove on the other splicing sleeve.
[0010] The utility model is further configured as follows: the upper end of the hard head is fixedly connected to a limiting ring, and the threaded sleeve is limited between the limiting ring and the inner liner.
[0011] The utility model is further configured as follows: the inner liner is formed by bonding three to five structural layers, and the material of the inner liner is PE or PE+EVOH.
[0012] The utility model is further configured as follows: the material of the bottle body is any one of PETG, PP, PET, PE, glass and PC.
[0013] In summary, the present invention has the following beneficial effects:
[0014] 1. The inner liner will deform as the pump is pressed until it fits with the pump head tube, thereby reducing the amount of cosmetic residue in the liner and ensuring the utilization rate of the cosmetics. The deformation of the inner liner makes it difficult for negative pressure to be generated inside the liner, making it difficult for air to enter the inner liner during the pressing process of the pump, thereby ensuring the life and service life of the cosmetics in the liner.
[0015] 2. The inner liner and the press pump are detachable, so that after the cosmetics in the inner liner are used up, people only need to replace the inner liner to reuse the cosmetic bottle, thereby improving the utilization rate of the bottle body and the press pump.
[0016] 3. The inner liner is a multi-layer structure, which makes it difficult for gas to penetrate the multi-layer structure and come into contact with cosmetics, thereby improving the preservation ability of the inner liner and extending the service life of cosmetics.
