Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic packaging bottles, in particular to a cosmetic packaging bottle. Background Art

[0002] A cosmetics packaging bottle is a container for holding cosmetics, which mainly includes a bottle body and a bottle cap. Generally, the bottle body includes an outer bottle body and an inner bottle body. The inner bottle body is mainly used to hold cosmetics, while the outer bottle body mainly plays a decorative and supporting role. With people's demand for the aesthetics of cosmetics packaging bottles, the production cost of the outer bottle body is relatively high, so cosmetics packaging bottles with replaceable inner bottles have appeared. This cosmetics packaging bottle is equipped with an inner bottle replacement, which can be replaced after the cosmetics in the inner bottle body are used up, so that the inner bottle body can be replaced and continued to be used, thereby reducing the cost of use.

[0003] In the prior art, there are many ways to connect the outer bottle body and the inner bottle body. For example, CN219791046U discloses a vacuum cream jar with a fully plastic replaceable inner bottle. This vacuum cream jar is provided with a notch on the opening side of the outer bottle body, and a fan-shaped protrusion is provided on the inner bottle body. The inner bottle body is installed in the outer bottle body corresponding to the notch by the protrusion, and the inner bottle body is positioned in the outer bottle body by the connection seat and the outer bottle body thread. Although this connection method is simple and easy to install, the two may be separated during transportation, and since the existing filling method is generally automatic filling, the outer bottle body and the inner bottle body will rotate and shake during the automatic filling process. When the connection seat is not installed, the connection between the inner bottle body and the outer bottle body is unstable, and the inner bottle body is easily separated from the outer bottle body, affecting the automatic filling operation.

[0004] For example, CN220236292U discloses a new type of combined replaceable liner structure for glass cream bottles. This replaceable liner structure fixes the glass bottle body and the liner by threaded connection. Although the fixation is relatively reliable, it is more troublesome to install and requires multiple rotations to fix the glass bottle body and the liner. Utility Model Content

[0005] The utility model aims at the deficiencies of the prior art and provides a cosmetic packaging bottle. The cosmetic packaging bottle is not only simple in structure and easy to assemble with an outer bottle body and an inner bottle body, but also has a reliable structure and is not easy to separate during transportation. During automatic filling, the inner bottle body can also be reliably positioned with the outer bottle body, and it is also very convenient to replace the inner bottle body after the cosmetics are used up.

[0006] In order to solve the above technical problems, the utility model solves the problems through the following technical solutions: a cosmetic packaging bottle, comprising an outer bottle body, an inner bottle body and a cover body, the cover body is covered on the outer bottle body, the outer wall of the bottle mouth side of the outer bottle body is provided with a transverse groove, one side of the top of the transverse groove is provided with an opening, and the other side of the top of the transverse groove is provided with a clamping strip, an extension ring is radially provided outwardly on the bottle mouth side of the inner bottle body, the extension ring is provided with a connecting ear extending toward the bottom of the inner bottle body, the connecting ear is provided with a limit block extending toward the inside of the inner bottle body, a limit space for clamping the clamping strip is formed between the limit block and the extension ring, the limit block enters the transverse groove from the opening, and the inner bottle body is rotated to clamp the clamping strip into the limit space. When assembling this cosmetic packaging bottle, the limiting block enters the transverse groove from the opening, and the inner bottle body is rotated to lock the locking strip into the limiting space, so that the inner bottle body is reliably fixed in the outer bottle body, and it is not easy to separate during transportation. In addition, during automatic filling, the inner bottle body can also be reliably positioned with the outer bottle body, and it is also very convenient to replace the inner bottle body after the cosmetics are used up.

[0007] In the above technical solution, the outer bottle body is threadedly connected to the cover body, and the outer bottle body and the cover body clamp the extension ring.

[0008] In the above technical solution, a shoulder sleeve is threadedly connected to the bottle mouth of the outer bottle body, the outer bottle body and the shoulder sleeve clamp the extension ring, a vacuum pump head is arranged on the shoulder sleeve, a piston is arranged in the inner bottle body, a first air hole is arranged at the bottom of the inner bottle body, and an air passage is provided between the outer bottle body and the inner bottle body. With this structure, the structure of the cosmetic packaging bottle is used as a vacuum bottle.

[0009] In the above technical solution, the outer bottle body is a glass bottle, and the outer wall of the inner bottle body near the bottle mouth is provided with a plurality of raised support ribs, and the support ribs are against the inner wall of the outer bottle body, and the air channel is formed between the support ribs. Since the precision of glass bottles is poor during the production process, the shaking between the inner bottle body and the outer bottle body can be avoided by adding support ribs, and since the precision of glass bottles is poor, the support ribs can be directly against the inner wall of the outer bottle body to form an air channel between the support ribs without adding holes on the glass bottles.

[0010] In the above technical solution, the outer bottle body is a plastic bottle, and the airway is a second air hole arranged at the bottom of the outer bottle body. Since the processing precision of plastic bottles is relatively good, in order to ensure the normal ventilation of the vacuum bottle, a second air hole needs to be arranged at the bottom of the outer bottle body as an airway.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when assembling the cosmetic packaging bottle, the limiting block enters the transverse groove from the opening, and the inner bottle body is rotated to clamp the locking strip into the limiting space, so that the inner bottle body is reliably fixed in the outer bottle body, and it is not easy to separate during transportation. In addition, during automatic filling, the inner bottle body can also be reliably positioned with the outer bottle body, and it is also very convenient to replace the inner bottle body after the cosmetics are used up.
