Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging bottle. Background Technology

[0002] Lip gloss is a cosmetic product specifically designed for the lips. After application, it can achieve a moisturizing, plump, and glossy effect, making it very popular among modern consumers. However, due to the texture of existing lip glosses, they may separate after prolonged storage.

[0003] To address the issue of layering, lip gloss packaging bottles with stirring capabilities have been introduced on the market. For example, CN220571714U discloses a lip gloss cosmetic product with a stirring function, including a bottle body, a cap, a central rod installed inside the cap, and a rotating stirring sleeve inside the bottle body. The central rod rotates within the bottle body, causing the stirring sleeve to rotate as well. Therefore, when using the cosmetic, simply twisting the cap rotates the central rod, which in turn rotates the stirring sleeve left and right, thus evenly stirring the cosmetic to restore its normal shape.

[0004] However, the stirring sleeve in the above-mentioned types of packaging bottles is relatively large, taking up space for cosmetics inside the bottle. On the other hand, most existing lip gloss bottles are made of transparent material, and the presence of the stirring sleeve makes the overall appearance less attractive. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a cosmetic packaging bottle.

[0006] A cosmetic packaging bottle includes a bottle body with a mouth for holding cosmetics and a cap that cooperates with the mouth to seal the bottle body. The cap is connected to a brush rod that extends into the bottle body from the mouth and a brush head fixed to the end of the brush rod for application. The mouth is provided with an inner plug with a perforation. The brush rod passes through the perforation and is transitionally fitted to it. The brush rod and the cap are rotatably connected. The brush rod has a helical section. When the helical section passes through the perforation, the inner plug acts on the brush rod, causing it to rotate.

[0007] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] See Figures 1-5 One embodiment of this application provides a cosmetic packaging bottle, including a bottle body 200 with a bottle mouth 220 for holding cosmetics and a cap 100 that cooperates with the bottle mouth 220 to close the bottle body 200. In the figure, the cap 100 is threadedly connected to the bottle mouth 220, that is, the cap 100 is provided with an internal thread and the bottle mouth 220 is provided with an external thread. The internal thread and the external thread cooperate to fix the two.

[0044] The cap 100 is connected to a brush rod 300 extending from the bottle opening 220 into the bottle body 200, and a brush head 301 fixed to the end of the brush rod 300 for application. An inner plug 400 with a perforation 432 is provided at the bottle opening 220, and the brush rod 300 passes through the perforation 432 and is fitted therewith. In the illustration, the brush head 301 is provided with a positioning post 302, and the brush rod 300 is provided with a positioning hole 303 that engages with the positioning post 302; the two work together to achieve fixation. The transition fit between the brush rod 300 and the perforation 432 is used to scrape away residual liquid; it can be either a clearance fit or an interference fit. A clearance fit means the gap is small enough to scrape away most of the liquid; an interference fit is preferred.

[0045] To address the issue of cosmetic layering, existing packaging bottles typically include a stirring sleeve within 200mm of the bottle body. However, this stirring sleeve is bulky, taking up considerable space, and also results in a less aesthetically pleasing overall appearance.

[0046] Therefore, in order to solve this problem, the brush rod 300 and the cover 100 of this application are rotatably connected. The brush rod 300 has a spiral section 311. When the spiral section 311 passes through the through hole 432, the inner plug 400 acts on the brush rod 300 to drive it to rotate.

[0047] When the brush rod 300 is inserted or removed, that is, when the spiral section 311 passes through the perforation 432, the inner plug 400 will apply a tangential force to the spiral section 311, thereby causing the brush rod 300 to rotate. The brush rod 300 will then drive the brush head 301 to rotate inside the bottle 200, thereby stirring the cosmetics inside the bottle 200 and improving the problem of cosmetic layering.

[0048] See Figures 1-3 The brush handle 300 includes a handle 310 and a connector 320 that plugs into the cover 100. The spiral section 311 is a portion of the handle 310. Considering structural strength, the handle 310 and connector 320 are integrally formed. To facilitate connection with the cover 100, one of the cover 100 and connector 320 is provided with an annular groove 321, and the other is provided with a protrusion 110 that engages with the annular groove 321; the two work together to achieve axial fixation.

[0049] In this embodiment, the annular groove 321 is provided on the outer wall of the connector 320, and the protrusion 110 is an annular structure, provided on the inner wall of the cover 100, and located above the internal thread.

[0050] To facilitate fixing, the connector 320 has a tapered guide portion 322 that guides the protrusion 110 to engage with the annular groove 321. During actual assembly, since the protrusion 110 is located above the internal thread and is relatively deep, a large force is required to force the guide portion 322 over the protrusion 110, making the overall assembly more troublesome. Furthermore, the process of forcibly overcoming the protrusion may cause deformation of the component, affecting the smoothness of the subsequent rotation of the brush rod 300.

[0051] To address this issue, the connector 320 of this application has a hollow structure with longitudinally extending slits 323 on its sidewalls. The slits 323 extend to the bottom of the annular groove 321. In this embodiment, there are two slits 323, which are symmetrically distributed. The two slits 323 divide the guide portion 322 into two symmetrical parts. As the guide portion 322 passes over the protrusion 110, the protrusion 110 and the outer peripheral wall of the guide portion 322 are squeezed together. At this time, the two parts adaptably move inward and deform, so that the guide portion 322 can easily pass over the protrusion 110 (the slits 323 reset after the guide portion 322 passes over the protrusion 110), allowing the annular groove 321 and the protrusion 110 to cooperate smoothly with each other.

[0052] See Figure 2 The connector 320 contacts and seals with the inner plug 400, giving the cosmetics a good sealing effect and preventing them from being contaminated or spoiled by external factors.

[0053] In this embodiment, the brush head 301 is a flat brush. A flat brush can generate a large stirring force when rotating, which can better stir the cosmetics and solve the problem of layering.

[0054] See Figures 4-5 The inner plug 400 and the bottle mouth 220 are fixedly connected, and have an axial limiting mechanism and a circumferential limiting mechanism. Specifically, the axial limiting mechanism includes a protruding ring 440 disposed on the outer peripheral wall of the inner plug 400 and a groove 221 disposed on the inner wall of the bottle mouth 220 that cooperates with the protruding ring 440; the circumferential limiting mechanism includes a positioning rib 450 disposed on the outer peripheral wall of the inner plug 400 and an axially arranged positioning groove 222 disposed on the inner wall of the bottle mouth 220 that cooperates with the positioning rib 450. In order to make the force more even, the number of positioning ribs 450 can be set according to the needs. This application does not make special requirements. In this embodiment, the number of positioning ribs 450 is 4, and they are evenly arranged along the circumference.

[0055] The inner stopper 400 has a radially enlarged overlapping portion 410, a central connecting portion 420, and an inverted conical scraping portion 430. The bottom end of the scraping portion 430 is provided with a platform 431 with a perforation 432. After the inner stopper 400 is fixed to the bottle neck 220, the overlapping portion 410 is exposed outside the bottle neck 220 and abuts against the top surface of the bottle neck 220. The outer surface of the overlapping portion 410 is flush with the outer surface of the bottle neck 220, making the overall appearance more aesthetically pleasing.

[0056] In this embodiment, the perforation 432 is non-circular; preferably, see [reference needed]. Figure 3 and Figure 5The rod 310 also includes a straight section 312 that extends from the spiral section 311 and connects to it (the straight section 312 is located at both ends of the rod 310, and the spiral section 311 is located in the middle of the rod 310). The straight section 312 and the spiral section 311 have the same cross-sectional shape, both of which can be adapted to the perforation 432. The perforation 432 is a rounded rectangle, which can restrict the circumferential rotation of the straight section 312 and can also scrape off excess cosmetics adhering to the surface of the brush rod 300 and the brush head 301, thereby reducing cosmetic waste.

[0057] The preferred pitch of the aforementioned helical segment 311 is 12.0 mm to 19.5 mm.

[0058] In another embodiment, see Figures 6-7 The straight section 312 and the spiral section 311 have a regular hexagonal cross-sectional shape. Correspondingly, the perforation 432 is also a regular hexagonal shape. Of course, the rod 310 can also be set as a non-circular structure. The specific choice can be made according to the requirements. This application will not elaborate further.

[0059] In one embodiment, the bottle body 200 includes a bottle body 210 with a uniform diameter, and a bottle mouth 220 has a shoulder 223 connected to the bottle body 210. For ease of installation, the top of the bottle body 210 has a radially reduced diameter portion 211. The inner peripheral wall of the shoulder 223 is provided with an annular groove 224 for the reduced diameter portion 211 to extend into and fit. The reduced diameter portion 211 and the annular groove 224 can be fixed by glue or a snap-fit ​​structure. This application does not make specific requirements. The outer surfaces of the bottle body 210 and the shoulder 223 are flush, and the overall shape is more aesthetically pleasing.

[0060] 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.

[0061] 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.
