Description

Technical Field

[0001] This utility model provides a cosmetic packaging bottle with anti-tipping function, which relates to the field of packaging bottle technology. Background Technology

[0002] Cosmetics are daily chemical products used to modify and care for the skin, hair, and face. Their core functions include cleansing, moisturizing, whitening, anti-aging, and makeup application. Cosmetic packaging bottles are containers that hold cosmetics. Their core functions are to protect the product (prevent leakage, contamination, and freshness), facilitate use, and convey brand quality.

[0003] For aesthetic reasons, existing cosmetic packaging bottles are typically designed as tall, slender cylindrical or square shapes. However, this also makes the bottles prone to tipping over. Especially in actual use, female users often don't immediately close the cap after opening it, but instead proceed to the next skincare or makeup step. Sometimes, due to actions during makeup application, the bottle is easily bumped. Since cosmetics are mostly liquids or lotions, which are easily flowable, tipping over will result in direct leakage and waste.

[0004] To address the issue of cosmetic bottles easily tipping over, existing technologies typically employ methods such as adding weight and increasing the bottom contact area. However, traditional weight-adding only lowers the bottle's center of gravity and doesn't provide a self-righting effect when the bottle is bumped. Cosmetic bottles are inherently small products, with limited space available for increasing the bottom area, thus failing to achieve the desired effect. Some products increase the contact area to achieve the desired effect, but this results in an unattractive appearance and occupies a significant amount of space, making them inconvenient to place and carry in situations with limited space, such as on a vanity or in a cosmetic bag. Therefore, we propose a cosmetic bottle with an anti-tipping function. Utility Model Content

[0005] This utility model provides a cosmetic packaging bottle with an anti-tipping function, aiming to solve the problems that the existing anti-tipping cosmetic packaging bottles do not have a self-correcting effect due to the counterweight, and that the packaging bottles are not aesthetically pleasing, inconvenient to place and carry, due to the purpose of increasing the contact area.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a cosmetic packaging bottle with anti-tipping function, comprising: The bottle body has an expansion groove at the bottom, and several expansion grooves are evenly arranged around the circumference of the bottle body. The expansion grooves are equipped with retractable expansion pieces, which are used to increase the support area at the bottom of the bottle body. A bottle cap is located at the top of the bottle body and is threadedly connected to the bottle body; A linkage structure is provided between the extension piece and the bottle cap, which is used to make the extension piece extend and retract within the extension groove as the bottle cap opens and closes, thereby achieving linkage. An inner lining support is provided at the bottom of the bottle body and smoothly transitions with the inner wall of the bottle body. The inner lining support is configured as a concave hemispherical bottom. A counterweight is disposed at the bottom of the inner liner and is eccentrically positioned relative to the central axis of the bottle. The counterweight works in conjunction with the inner liner to lower the center of gravity of the bottle and achieve automatic return to center.

[0007] Preferably, the linkage structure includes: A vertical tube is set inside the bottle, with its bottom end penetrating through the inner substrate support to the expansion groove. The bottom of the vertical tube has through holes that correspond one-to-one with the expansion pieces. The expansion pieces have mounting holes coaxially opened at the positions corresponding to the through holes. A pull rope is installed inside the riser, with one end of the pull rope extending downward through the through hole into the mounting hole and fixedly connected to the end face of the mounting hole. The pull rope is used to pull the extension piece back into the extension slot. The second return spring is disposed in the mounting hole, with one end fixed to the end face of the mounting hole and the other end fixed to the side wall of the riser. The second return spring is used to drive the extension piece to extend out of the extension slot. The second magnet is slidably disposed inside the riser, and its bottom is fixedly connected to the other end of the pull rope. A first reset spring is disposed inside the riser. Its top end is fixed to the bottom of the second magnet, and its bottom end is fixed to a limit ring. The limit ring is fixed to the inside of the riser. The first reset spring is used to pull the second magnet to move downward. A first magnet is disposed inside the bottle cap, and the two ends of the first magnet and the second magnet are opposite magnetic poles. The first magnet is used to pull the second magnet upward.

[0008] Preferably, the bottom outer side of the extension piece is provided with a step, and the bottom of the extension groove is provided with a notch that mates with the step.

[0009] Preferably, the counterweight is offset from the central axis of the bottle by 15°.

[0010] Preferably, a guide tube is also fixedly connected inside the mounting hole, and the guide tube is sleeved on the outside of the pull rope.

[0011] Preferably, the sidewall of the second magnet has a groove along the longitudinal direction.

[0012] Preferably, a sealing gasket is fixed to the bottom of the first magnet.

[0013] Preferably, the bottom of the bottle body is provided with an anti-slip groove, and an anti-slip mat is provided in the anti-slip groove.

[0014] Preferably, the top of the bottle has uniformly distributed liquid outlet holes.

[0015] The beneficial effects of this utility model are: A counterweight is placed at the bottom of the bottle to lower the bottle's center of gravity. This "heavy at the bottom and light at the top" principle reduces the probability of tipping over. At the same time, the counterweight's center of gravity is biased to one side. When the bottle tip over (tilt angle ≤ 30°), the center of gravity will generate a larger "restoring torque" around the contact point, causing the bottle to swing back and automatically return to its original position.

[0016] When the cap is screwed on, the extension piece automatically retracts into the extension slot, keeping the bottle in its normal shape and not affecting its appearance. It also saves storage space and makes the bottle easy to carry. When the cap is unscrewed, the extension piece automatically extends out of the extension slot to support the bottle, preventing it from tipping over and leaking cosmetics when the bottle is open, thus avoiding waste.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Reference Figures 1 to 7 This utility model provides a cosmetic packaging bottle with anti-tipping function, including a bottle body 2 and a bottle cap 1. The bottom of the bottle body 2 is provided with an expansion groove 22, and several expansion grooves 22 are evenly arranged around the circumference of the bottle body 2. The expansion groove 22 is provided with a retractable expansion piece 8, and a linkage structure 3 is provided between the expansion piece 8 and the bottle cap 1.

[0025] Specifically, the extension piece 8 is used to increase the bottom area of ​​the bottle body 2, making the packaging bottle more stable. Through the setting of the linkage structure 3, when the bottle cap 1 is screwed on, the extension piece 8 automatically retracts into the extension groove 22, and the bottle body 2 maintains its normal shape, without affecting its appearance, which can save storage space and make it convenient to carry; when the bottle cap 1 is unscrewed, the extension piece 8 automatically extends out of the extension groove 22 to support the bottle body 2, which can prevent the bottle body 2 from tipping over during use and causing cosmetic leakage, thus avoiding waste.

[0026] Reference Figure 1 , Figure 3 , Figure 4 The bottom of the bottle body 2 is provided with an inner substrate support 10, which smoothly transitions with the inner wall of the bottle body 2 and is set as a concave hemispherical bottom; the bottom of the inner substrate support 10 is provided with a counterweight 11, which is set 15° off-center from the central axis of the bottle body 2.

[0027] Specifically, a counterweight 11 is set at the bottom of the bottle body 2 so that the center of gravity of the bottle body 2 is downward. By relying on the "heavy bottom and light top", the probability of tipping is reduced. At the same time, the center of gravity is biased to one side. When the bottle body 2 is tipped over (tilt angle ≤ 30°), the center of gravity will form a larger "restoring torque" around the contact point, causing the bottle body 2 to swing back and achieve automatic return to the correct position.

[0028] Reference Figure 1 , Figures 3-7The linkage structure 3 includes a vertical tube 9 set inside the bottle body 2, the bottom end of which passes through the inner substrate support 10 to the expansion groove 22. The bottom of the tube 9 has through holes 20 corresponding to the expansion pieces 8. The expansion pieces 8 have mounting holes 19 coaxially opened at the positions corresponding to the through holes 20. A pull rope 15 is provided inside the tube 9. One end of the pull rope 15 extends downward through the through hole 20 into the mounting hole 19 and is fixedly connected to the end face of the mounting hole 19. The other end is fixedly connected to a second magnet 12. The second magnet 12 is slidably set inside the tube 9. A second return spring 17 is provided inside the mounting hole 19. One end of the spring is fixedly connected to the end face of the mounting hole 19, and the other end is fixedly connected to the side wall of the tube 9. A limit ring 14 is also fixedly connected inside the tube 9. A first return spring 13 is fixedly connected between the second magnet 12 and the limit ring 14. A first magnet 5 is provided inside the bottle cap 1. The two ends of the first magnet 5 and the second magnet 12 are opposite magnetic poles.

[0029] Specifically, when the bottle cap 1 is screwed on, the first magnet 5 attracts the second magnet 12 to the top of the riser 9. At this time, the pull rope 15 is taut, pulling the extension piece 8 into the extension groove 22. The first return spring 13 is in a stretched state, and the second return spring 17 is in a compressed state, and the bottle body 2 maintains its normal shape. When the bottle cap 1 is unscrewed, the attraction of the first magnet 5 is released, and the second magnet 12 moves downward under the action of the first return spring 13. The pull rope 15 is relaxed, and the second return spring 17 pops the extension piece 8 out of the extension groove 22. Thus, when using cosmetics, if the bottle body 2 is placed on the table without the bottle cap 1, the extension piece 8 can increase the bottom area of ​​the bottle body 2 and support the bottle body 2, thereby achieving the purpose of preventing tipping.

[0030] Reference Figure 1 , Figure 5 , Figure 6 , Figure 7 The bottom outer side of the extension piece 8 is provided with a step 21, and the bottom of the extension groove 22 is provided with a notch 7 that matches the step 21.

[0031] Specifically, after the extension piece 8 retracts into the extension slot 22, the step 21 engages with the notch 7. After the extension piece 8 extends out of the extension slot 22, the step 21 contacts the placement platform. The evenly arranged multiple extension pieces 8 are equivalent to multiple supports, which support the bottle body 2.

[0032] Reference Figure 6 A guide tube 18 is also fixedly connected inside the mounting hole 19, and the guide tube 18 is sleeved on the outside of the pull rope 15. The guide tube 18 guides the pull rope 15 and prevents the pull rope 15 from getting tangled with the second return spring 17 inside the mounting hole 19.

[0033] Reference Figure 5 The second magnet 12 has a groove 16 longitudinally formed on its side wall. The groove 16 serves as a through passage, ensuring that the second magnet 12 can slide smoothly inside the riser 9.

[0034] Reference Figure 1 , Figure 3 A sealing gasket 6 is fixed to the bottom of the first magnet 5. The sealing gasket 6 isolates the first magnet 5 from the top of the bottle body 2, preventing the cosmetic from directly contacting the first magnet 5, and also provides a sealing effect.

[0035] Reference Figure 1 , Figure 7 The bottom of the bottle 2 also has an anti-slip groove 23, and an anti-slip pad 24 is installed inside the anti-slip groove 23. The anti-slip pad 24 further improves the stability of the bottle 2 when placed.

[0036] Reference Figure 1 , Figure 2 The top of the bottle 2 has evenly spaced dispensing holes 4. These holes 4 are used to pour out cosmetics.

[0037] Working principle: When the bottle cap 1 is screwed on, the first magnet 5 attracts the second magnet 12 to the top of the riser 9. At this time, the pull rope 15 is taut, pulling the extension piece 8 into the extension slot 22. The first return spring 13 is in a stretched state, and the second return spring 17 is in a compressed state. The bottle body 2 maintains its normal shape, which can save storage space and is convenient to carry. When the bottle cap 1 is unscrewed, the second magnet 12 moves downward under the action of the first return spring 13, the pull rope 15 is relaxed, and the second return spring 17 pops the extension piece 8 out of the extension slot 22. The extension piece 8 increases the bottom area of ​​the bottle body 2 and supports the bottle body 2, thus achieving the purpose of preventing tipping.

[0038] A counterweight 11 is set at the bottom of the bottle body 2 so that the center of gravity of the bottle body 2 is downward. By relying on the "heavy bottom and light top", the probability of tipping is reduced. At the same time, the center of gravity of the counterweight 11 is biased to one side. When the bottle body 2 is tipped over (tilt angle ≤ 30°), the center of gravity will form a larger "restoring torque" around the contact point, causing the bottle body 2 to swing back and achieve automatic return to the correct position.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
