When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.

[0034] See Figures 1-5 One embodiment of this application provides a cosmetic packaging bottle, including a bottle body 100, a vacuum pump assembly 200, a shoulder cover 300, and a press cap 400.

[0035] The bottle body 100 has a single-layer structure and a container space 110 for holding cosmetics. Inside the container space 110, there is a piston 111 that fits with the bottle body 100 with a clearance.

[0036] The vacuum pump assembly 200 includes a pump base 210 resting on the bottle body 100 and covering the accommodating space 110, and a pump body 220 positioned and mounted on the pump base 210 and partially extending into the accommodating space 110. A shoulder sleeve 300 connects to the opening 120 of the bottle body 100 and is used to fix the pump base 210. In the figure, the outer peripheral surface of the opening 120 is provided with an external thread 121, and correspondingly, the inner peripheral surface of the shoulder sleeve 300 is provided with an internal thread 311. The external thread 121 and the internal thread 311 engage to achieve fixation.

[0037] Further, see Figure 1 and Figure 3 The shoulder sleeve 300 of this application includes a base 310 and a reduced diameter section 320. The internal thread 311 is provided on the inner surface of the base 310, so that after it is fitted with the bottle body 100, the outer surface of the base 310 is flush with the outer surface of the bottle body 100. The reduced diameter section 320 can fit with the cap 500 to achieve the outer surfaces of the cap 500, the shoulder sleeve 300 and the bottle body 100 being flush, making the overall appearance more aesthetically pleasing.

[0038] See Figures 1-2 The pressing cap 400 is movably fitted with the shoulder sleeve 300 and is positioned above the vacuum pump assembly 200. It partially (in the middle position) inserts into the pump body 220 and has a liquid outlet 410 that connects to the accommodating space 110 via the pump body 220. Of course, considering that the pressing cap 400 can be reset, a spring (not shown in the figure) can be provided between the pump base 210 and the pressing cap 400.

[0039] In the diagram, the top of the press cap 400 has a circular surface that can be pressed. The ratio of its diameter to the diameter of the narrow section 320 is 0.7 to 0.9:1. The pressing area is relatively large. However, since the pressing area is limited when the hand presses down on the press cap 400, it is very easy to cause unbalanced pressing. Therefore, the press cap 400 may warp or even fall off the shoulder cover 300.

[0040] To address the aforementioned issues, this application incorporates an anti-slip structure between the shoulder cover 300 and the pressure cap 400. The anti-slip structure can be, for example... Figure 1 and Figure 2As shown, the top of the reduced diameter section 320 has an inward flange 323, and the edge of the press cap 400 has an outward folded edge 401. The folded edge 401 is located below the inward flange 323. Even under the action of the spring, the folded edge 401 will at most only abut against the lower surface of the inward flange 323, and will not cause the press cap 400 to come off.

[0041] The cosmetic packaging bottle of this application sets the pump base 210 and the shoulder sleeve 300 as separate structures. After assembling the shoulder sleeve 300 and the press cap 400, it is fixed to the pump base 210. When cosmetics are needed, the press cap 400 is pressed down. Even under unbalanced pressing, due to the presence of the anti-detachment structure, the folded edge 401 of the press cap 400 can be restricted below the inner folded edge 323 of the shoulder sleeve 300. Compared with the prior art where the press cap 400 is easy to warp / fall off, the press cap 400 of this application has the function of preventing warping / falling off.

[0042] In this embodiment, the shoulder sleeve 300 and the pump seat 210 are engaged. See details. Figures 1-4 The inner circumferential surface of the shoulder sleeve 300 and the edge of the pump base 210 are respectively provided with a first locking tooth 321 and a second locking tooth 211 that cooperate to restrict their relative rotation. Among them, multiple sets of first locking teeth 321 are evenly distributed in the circumferential direction. In each set, there are multiple first locking teeth 321, which can be set according to the requirements. Of course, the first locking teeth 321 can also be arranged around the inner circumferential surface of the shoulder sleeve 300. This application does not make any special requirements.

[0043] Furthermore, of both the shoulder sleeve 300 and the pump base 210, one is provided with a protruding ring 322, and the other is provided with a groove 212 that cooperates with the protruding ring 322 to restrict the axial movement of both. In the figure, the protruding ring 322 is provided in the shoulder sleeve 300, and the groove 212 is provided in the pump base 210. This design allows the two to be inserted arbitrarily without the need for alignment during assembly, thus improving assembly efficiency.

[0044] To avoid interference, both the first retaining tooth 321 and the convex ring 322 are positioned above the internal thread 311 (specifically located in the reduced diameter section 320).

[0045] To improve the sealing of cosmetic packaging bottles, an annular protrusion 213 is arranged on the outer periphery of the pump base 210. A gap exists between the annular protrusion 213 and the opening 120 of the bottle body 100. This gap is used to install a sealing ring (not shown in the figure; the specific installation location can be found in [reference needed]). Figure 1 (P position in the text).

[0046] See Figures 4-5The pump base 210 has a centrally located post 214 for mounting the pump body 220. The pump base 210 includes an axially extending annular wall 215 that engages with the shoulder sleeve 300, and a transition wall 216 extending between the annular wall 215 and the post 214. The transition wall 216 is at least partially inclined. In this embodiment, the lower surface of the transition wall 216 is inclined.

[0047] Further, see Figure 1 The upper surface shape of piston 111 is adapted to the lower surface shape of vacuum pump assembly 200. Piston 111 has a thin-walled structure, including a bottom wall 112 that corresponds to pump body 220 and extends horizontally, an annular wall 113 that is in clearance fit with bottle body 100, and an extension wall 114 located between annular wall 113 and bottom wall 112. Extension wall 114 is at least partially inclined.

[0048] This design allows cosmetics to slide down the extension wall 114 to the bottom wall 112 of the piston 111, preventing the pump from drying out during use. When the piston 111 rises to its highest position, it can engage with the transition wall 216, minimizing material residue and reducing cosmetic waste.

[0049] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0050] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
