[0002] Cosmetic packaging bottles are used to package and store cosmetics. They are widely used in the production and use of cosmetics and are indispensable storage and packaging equipment for cosmetics. They have good packaging effects. As the demand for cosmetics gradually increases, people's aesthetic appreciation of cosmetic packaging bottles is also gradually improving.

[0003] Many exquisitely designed glass packaging bottles have appeared on the consumer market. For example, utility model patent CN217295671U discloses a glass vacuum bottle, including a glass bottle body, a pressing component, an adjusting piston, and a dispensing component. The glass bottle body has a bottle mouth and a bottle bottom, and the bottom of the glass bottle body has a vent hole for air circulation… The aforementioned glass vacuum bottle requires a vent hole at the bottom of the glass bottle body; only with this vent hole can the piston be driven to dispense material using the air pressure difference. Manufacturing the vent hole in the glass bottle requires a relatively complex process, is quite tedious, and may result in breakage during the manufacturing process. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art. Therefore, the purpose of the present invention is to provide a polygonal packaging bottle.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A polygonal packaging bottle includes a bottle body, an inner liner disposed within the bottle body, a vacuum pump threadedly connected to the inner liner, a shoulder sleeve disposed on the bottle body, and a piston disposed within the inner liner. The piston is tightly fitted to the inner wall of the inner liner, and a gap is left between the inner liner and the bottle body, forming an air chamber between them. A protrusion is provided at the bottom of the inner part of the bottle body, and the piston is located on the protrusion. The protrusion lifts the piston, allowing the air chamber to communicate with the bottom of the piston.

[0007] Further, based on the above solution, a gap is left between the vacuum pump and the shoulder sleeve, forming a first air intake channel between them. The shoulder sleeve is provided with multiple pressing parts, which press against the inner liner. A gap is left between the multiple pressing parts, forming a second air intake channel between them.

[0008] Furthermore, based on the above solution, a positioning groove is provided on the bottle body, and a positioning component is provided on the inner liner, the positioning component being used in conjunction with the positioning groove.

[0009] Furthermore, based on the above solution, a first connecting part is provided on the bottle body, and a second connecting part is provided on the shoulder sleeve, the second connecting part being used in conjunction with the first connecting part.

[0010] Furthermore, based on the above scheme, the bottle body has a square structure, and the shoulder sleeve has a square structure.

[0011] Building upon the above solution, the first connecting part consists of four buckles, and the second connecting part consists of four slots, with two of the slots extending to one end of the shoulder cover.

[0038] Example 1:

[0039] like Figure 1-5 As shown, a polygonal packaging bottle includes a bottle body 1, an inner liner 2 disposed in the bottle body 1, a vacuum pump 3 threadedly connected to the inner liner 2, a shoulder sleeve 4 disposed on the bottle body 1, and a piston 5 disposed in the inner liner 2. The bottle body 1 is a transparent glass structure. The piston 5 is tightly fitted to the inner wall of the inner liner 2, and a gap is left between the inner liner 2 and the bottle body 1, forming an air chamber 6. A large amount of gas stored in the air chamber 6 is used to push the piston 5 to extract material. This eliminates the need to open a gas guide hole on the glass bottle body 1, ensuring the integrity of the bottle body 1. An annular protrusion 101 is provided at the middle position of the bottom of the bottle body 1. The piston 5 is located on the protrusion 101. The protrusion 101 lifts the piston 5, so that the air chamber 6 communicates with the bottom of the piston 5, allowing gas to enter the bottom of the piston 5 and push the piston 5 upward.

[0040] In this embodiment, the protrusion 101 and the bottle body 1 are an integral structure, which can eliminate splicing steps, reduce production complexity, and improve yield.

[0041] Please refer to the following for details. Figure 2 and 3To prevent insufficient gas in the gas chamber 6 from causing the piston 5 to fail to rise, this application leaves a gap between the vacuum pump 3 and the shoulder sleeve 4, forming a first air inlet 7. The shoulder sleeve 4 is provided with multiple pressing parts 401, which press against the inner liner 2. A gap is left between the multiple pressing parts 401, forming a second air inlet 8. When the end cover is opened, external gas can enter the gas chamber 6 through the first air inlet 7 and the second air inlet 8 to replenish the gas in the gas chamber 6.

[0042] In this embodiment, there are two pressing parts 401 arranged symmetrically, and there are also two second air intakes 8 arranged symmetrically.

[0043] In this embodiment, the pressing part 401 has an arc-shaped structure.

[0044] Please refer to the following for details. Figure 4 The bottle body 1 has a recessed positioning groove 102, and the inner liner 2 has an outwardly extending positioning element 201. The positioning element 201 works in conjunction with the positioning groove 102. When installing the inner liner 2, the positioning element 201 can be positioned and aligned with the positioning groove 102. When the inner liner 2 is installed in place, the positioning element 201 is located in the positioning groove 102 and is restricted by the positioning groove 102, so that the inner liner 2 will not rotate.

[0045] Please refer to the following for details. Figure 4 and 5 The bottle body 1 is provided with a first connecting part 103, and the shoulder sleeve 4 is provided with a second connecting part 402. The second connecting part 402 is used in conjunction with the first connecting part 103. The shoulder sleeve 4 is fixed to the bottle body 1 through the cooperation of the second connecting part 402 and the first connecting part 103, ensuring the stability of the connection between the shoulder sleeve 4 and the bottle body 1.

[0046] Please refer to the following for details. Figure 1 and 5 The bottle body 1 has a square structure, and the shoulder sleeve 4 also has a square structure, meaning that the entire packaging bottle has a quadrilateral structure.

[0047] Please refer to the following for details. Figure 4 and 5 The first connecting part 103 consists of four buckles, which are respectively located on the four sides of the top of the bottle body 1; the second connecting part 402 consists of four slots, which are respectively located on the four sides inside the shoulder sleeve 4, that is, the shoulder sleeve 4 can be fixed to the bottle body 1 by the snap-fit ​​between the slots and the buckles.

[0048] Please refer to the following for details. Figure 5Two opposing slots extend to the lower end of the shoulder sleeve 4, meaning there are two slots extending to the lower end of the shoulder sleeve 4. This allows some of the buckles to first enter the slots extending through the shoulder sleeve 4 during installation, serving as a pre-positioning mechanism. Then, the shoulder sleeve 4 is pressed down to secure it, ensuring the accuracy of the shoulder sleeve 4's installation position.

[0049] Please refer to the following for details. Figure 5 The shoulder cover 4 has a beveled part 403 inside, which is located below the slot. The design of the beveled part 403 makes it easy for the buckle to enter the slot.

[0050] Example 2:

[0051] like Figure 6-7 As shown, the bottle body 1 has a hexagonal structure, and the shoulder sleeve 4 has a circular structure, meaning the entire packaging bottle has a hexagonal structure.

[0052] Please refer to the following for details. Figure 7 The first connecting part 103 is an annular groove, which is opened on the outer top of the bottle body 1. The second connecting part 402 is an annular block, which is the downward extension of the second connecting part 402. The shoulder sleeve 4 can be fixed on the bottle body 1 by the engagement of the annular block and the annular groove.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
