Description

Technical Field

[0001] This application relates to the field of cosmetic packaging technology, 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, CN220571714 U 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's rotation within the bottle body drives the stirring sleeve to rotate. Therefore, to use the cosmetic, simply twisting the cap rotates the central rod, which in turn rotates the stirring sleeve left and right, thus stirring the product.

[0004] However, the layering of lip gloss is caused by the separation of oil and sediment, while the packaging bottle with the above structure is horizontally stirred, so the stirring effect is poor.

[0005] To further improve the product, lip gloss packaging bottles that can be stirred up and down have been introduced on the market. For example, document CN218281374U discloses a component with a stirring and mixing function. Although this type of stirring component can be stirred up and down, the stirring is not uniform enough. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a cosmetic packaging bottle.

[0007] A cosmetic packaging bottle includes a bottle body with a bottle mouth for holding cosmetics and a cap that cooperates with the bottle mouth to seal the bottle body. The cap is connected to a brush rod that extends into the bottle body from the bottle mouth and a brush head fixed to the end of the brush rod for application. The bottle mouth is provided with a perforated inner plug. The brush rod passes through the perforation and transitionally engages with the inner plug. The bottle body is also provided with a stirrer. The stirrer includes a lower stirring cylinder that is gap-fitted with the inner cavity of the bottle. The bottom of the lower stirring cylinder is open and includes a side wall and a top wall. The top wall has a positioning port that engages with the brush rod and a first through hole.

[0008] 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. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0009] Optionally, the first through hole is arranged around the positioning port.

[0010] Optionally, a second through hole is provided on the side wall, and the side wall is clearance-fitted with the inner wall of the bottle.

[0011] Optionally, the diameter of the second through hole is larger than the diameter of the first through hole.

[0012] Optionally, the sidewall has a square cross-section, and a second through hole is arranged on each side.

[0013] Optionally, the lower stirring cylinder is provided with multiple sets of second through holes, the second through holes in the same set are at the same horizontal height and arranged circumferentially.

[0014] Optionally, the stirrer includes an upper stirring cylinder, which has an inverted conical structure and its bottom is connected to the positioning port.

[0015] Optionally, the upper stirring cylinder and the top wall are an integral structure.

[0016] Optionally, the sidewall has a square cross-section, and the top of the upper stirring cylinder is flush with the outer surface of the sidewall.

[0017] Optionally, the brush rod is provided with a positioning groove that mates with the positioning port.

[0018] The cosmetic packaging bottle of this application has a first through hole on the top wall of the lower stirring cylinder. Since the diameter of the first through hole is small, the flow rate will increase when the fluid passes through the narrow hole. Therefore, when the stirring cylinder moves axially, the cosmetic can flow out of the first through hole at an accelerated speed. Compared with the prior art, the stirring is more uniform.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] See Figures 1 to 8c One embodiment of this application provides a cosmetic packaging bottle, including a bottle body 100 with a bottle opening 110 for holding cosmetics and a cap 200 that cooperates with the bottle opening 110 to close the bottle body 100. In the figure, the cap 200 is threadedly connected to the bottle opening 110; that is, the cap 200 has an internal thread, and the bottle opening 110 has an external thread. The internal and external threads cooperate to secure the two. The cosmetics described in this application are lip glosses, lip stains, and other easily separable cosmetics.

[0039] The cap 200 is connected to a brush rod 210 extending from the bottle opening 110 into the bottle body 100, and a brush head 220 fixed to the end of the brush rod 210 for application. An inner plug 300 with a perforation 310 is provided at the bottle opening 110. The brush rod 210 is fitted through the perforation 310 and the inner plug 300. The connection between the brush head 220 and the brush rod 210 can be varied. For example, as shown in the diagram, the brush head 220 has a positioning post, and the brush rod 210 has a positioning hole that engages with the positioning post, thus securing them together. The transition fit between the brush rod 210 and the perforation 310 is used to scrape away residual liquid. This 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.

[0040] In this embodiment, the cover 200 includes an outer cover 201 and an inner cover 202 that are fixedly connected. The brush rod 210 is connected to the inner cover 202, and the internal thread is also located on the inner cover 202.

[0041] To achieve vertical mixing, see [link / reference]. Figures 4a-4b The bottle body 100 of this application is provided with a stirrer 120 inside. The stirrer 120 includes a lower stirring cylinder 140 that is fitted with the inner cavity of the bottle body 100. The bottom of the lower stirring cylinder 140 is open and includes a side wall 160 and a top wall 150. The top wall 150 is provided with a positioning port 151 that engages with the brush rod 210. The top wall 150 is provided with a first through hole 152. Since the diameter of the first through hole 152 is small, the flow rate will increase when the fluid passes through the narrow hole. Therefore, when the stirrer 120 moves axially, the cosmetic can flow out of the first through hole 152 more quickly. Compared with the prior art, the cosmetic is stirred more evenly.

[0042] Preferably, a second through hole 161 is provided on the side wall 160. When the brush rod 210 moves axially with the stirrer 120, for example, when the stirrer 120 moves upward, refer to the direction of movement X in 5a, the cosmetic can flow from the first through hole 152 to the second through hole 161 (the arrow in the figure indicates the approximate flow direction). When the stirrer 120 moves downward, refer to... Figure 5b The cosmetic flows from the bottom into the second through-hole 161 and the first through-hole 152, further increasing the flow rate and improving the stirring efficiency. There are multiple first through-holes 152 and second through-holes 161; in this embodiment, there are 10 first through-holes 152, but the specific number can be chosen adaptively according to needs. Furthermore, the first through-holes 152 are arranged around the positioning port 151, and the diameter of the second through-hole 161 is larger than the diameter of the first through-hole 152. To ensure smooth stirring and allow the cosmetic to flow from the first through-hole 152 to the second through-hole 161, the sidewall 160 is fitted with the inner wall of the bottle body 100 with a clearance fit.

[0043] See Figures 4a-4b The side wall 160 has a square cross-section, and a second through hole 161 is arranged on each side. Furthermore, the lower stirring cylinder 140 is provided with multiple sets of second through holes 161, with the second through holes 161 in the same set at the same horizontal height and arranged circumferentially. In the figure, there are two sets of second through holes 161, each set containing the same number of holes, and the two sets of second through holes 161 are arranged vertically in a one-to-one correspondence in the axial direction.

[0044] In one embodiment, the stirrer 120 includes an upper stirring cylinder 130, which has an inverted conical structure and its bottom is connected to the positioning port 151. The upper stirring cylinder 130 not only increases the stirring area of ​​the stirrer 120, but also guides the brush rod 210 to extend into the positioning port 151, making it easier for it to engage with the stirrer 120. Of course, there are various ways to engage, such as providing a positioning groove 211 on the brush rod 210 that mates with the positioning port 151.

[0045] To ensure the brush handle 210 can smoothly detach from the stirrer 120 at its extreme position, the bottle body 100 includes a bottle body 101 and a bottle mouth 110 with a shoulder 102 connected to the bottle body 101. The bottle body 101 and shoulder 102 can be fixed by means of glue, snap-fit ​​structure, welding, etc., with their outer skins flush, resulting in a more aesthetically pleasing overall design. The inner wall of the bottle mouth 110 has a limiting step 111. At the extreme position, the top surface of the upper stirring cylinder 130 abuts against the limiting step 111. At this point, if an upward force is applied to the brush handle 210, the positioning groove 211 can smoothly disengage from the positioning port 151, allowing the brush handle 210 to be easily pulled out.

[0046] For details on the stirring process, please refer to [link / reference]. Figures 8a-8c When cosmetics are needed, the brush handle 210 moves the stirrer 120 upward. When the stirrer 120 reaches its limit position, the brush handle 210 can overcome the locking force and separate from the stirrer 120, that is, the brush handle 210 can continue to move upward. Correspondingly, the stirrer 120, after being separated from the brush handle 210, moves downward.

[0047] Furthermore, the upper stirring drum 130 and the top wall 150 are an integral structure, which increases the overall structural strength. Preferably, the top of the upper stirring drum 130 is flush with the outer surface of the side wall 160.

[0048] Cosmetic packaging bottles may be subjected to external forces such as vibration and impact during transportation or handling, which may cause the cap 200 to loosen. Considering this, this application also includes an anti-loosening structure, see [link to relevant documentation]. Figure 1 as well as Figures 6-7 A limiting part 112 is provided below the external thread, and a limiting groove 203 is provided at the bottom of the inner cover 202. The limiting groove 203 is composed of two limiting blocks with guide slopes (limiting block 204a and limiting block 204b respectively). One of the limiting blocks 204b is thicker. When the packaging bottle is closed, the limiting part 112 is in the limiting groove 203. The bottom of the limiting block 204a is slightly lower than the top of the limiting part 112 (the limiting part 112 can pass over the limiting block 204a to enter the limiting groove 203), while the bottom of the limiting block 204b is much lower than the top of the limiting part 112. Therefore, when the cosmetic needs to be rotated, a larger force is required to push the limiting part 112 over the limiting block 204a before it can be rotated and opened, avoiding loosening caused by external forces.

[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.
