Abstract
Description
Technical Field
[0001] The present application relates to cosmetic packaging technology, and particularly to a plug with a ventilation function and a cosmetic container including the plug. Background Art
[0002] Currently, in a cosmetic container, a plug is usually provided at the bottle mouth of the container. When the applicator is withdrawn from the container, the plug scrapes the material on the applicator to prevent excessive material on the applicator. The plug usually fits tightly with the applicator to achieve a good scraping effect, and the plug is usually hermetically connected to the bottle mouth of the container to prevent the liquid in the container from leaking from the bottle mouth. However, due to the good sealing performance of the plug, when the applicator is inserted into the container and then taken out, it is not only very laborious, but also the cosmetic material in the container is easily splashed out due to the sudden change in air pressure, resulting in pollution and waste of the material. Summary of the Invention
[0003] In order to overcome the above defects, the present application provides a plug with a ventilation function. A scraping lip is provided on the plug, and an exhaust passage is formed between the scraping lip and the brush rod. The air in the bottle body is timely discharged through the exhaust passage, thereby avoiding the situation that the cosmetic material in the bottle body is splashed out due to the sudden change in air pressure, resulting in pollution and waste of the material.
[0004] The technical solution adopted by the present application to solve its technical problems is as follows:
[0005] A plug with a ventilation function is installed at the bottle mouth of a bottle body. The plug includes a plug body. A scraping lip is provided on the inner side wall of the plug body. A brush rod is provided in the bottle body. A gap is formed between the scraping lip and the brush rod to form an exhaust passage. The exhaust passage communicates with the inner space and the outer space of the scraping lip. The inner space of the scraping lip refers to the space in the bottle body that is separated by the scraping lip and is far from the bottle mouth. The outer space of the scraping lip refers to the space in the bottle body that is separated by the scraping lip and is close to the bottle mouth.
[0006] Optionally, the first end of the scraping lip is fixedly connected to the inner side wall of the bottle body. The second end of the scraping lip extends radially inward along the plug body, and the second end of the scraping lip encloses a scraping hole. The exhaust passage is formed between the brush rod and the second end of the scraping lip.
[0007] Optionally, the radial cross-section of the brush rod is Pattern A, and the orthographic projection of the scraping hole on the bottom of the bottle body is Pattern B. The shapes of Pattern A and Pattern B are different.
[0008] Optionally, Pattern A is at least one of a circle, an ellipse, and a polygon, and Pattern B is at least one of a circle, an ellipse, and a polygon.
[0009] Optionally, the graphic A is a circle, the graphic B is a polygon, and the number of sides of the polygon is from 3 to 12.
[0010] Optionally, the graphic A is a circle, the graphic B is an equilateral hexagon, the brush rod and the plug body are coaxially arranged, the diameter of the graphic A is D1, the diameter of the inscribed circle of the graphic B is D2, and D1≥D2.
[0011] Optionally, any two points A and B are taken on the scraping lip. If the distance from point A to the second end of the scraping lip is less than the distance from point B to the second end of the scraping lip, then the thickness of the scraping lip at point A is less than the thickness of the scraping lip at point B, and the second end of the scraping lip is inclined towards the bottom side of the bottle body.
[0012] Optionally, a convex edge extends radially outwards from the first end of the plug body, and N spaced-apart stoppers extend radially outwards from the outer side wall of the plug body. The N stoppers are located at the same axial position of the plug body, where N is an integer and N≥2.
[0013] Optionally, the stopper is provided with a first surface and a second surface. The first surface is arranged perpendicular to the axis of the plug body, and an obtuse angle a is formed between the second surface and the axis of the plug body. The convex edge fits against the bottle mouth of the bottle body, and the first surface fits against the shoulder of the bottle body.
[0014] Optionally, a convex platform extends radially inwards along the inner side wall of the plug body, and the convex platform is located on the side of the scraping lip close to the bottle mouth of the bottle body.
[0015] The present application also provides a cosmetic container, including an inner plug, a cap assembly, a brush rod and a bottle body. The inner plug is installed at the bottle mouth of the bottle body. The first end of the brush rod is fixedly installed in the cap assembly, the second end of the brush rod is fixedly connected to a brush head, and the cap assembly is detachably covered on the bottle mouth of the bottle body.
[0016] The beneficial effects of the present application are as follows:
[0017] (1) In the present application, a scraping lip is provided on the inner plug, and an exhaust passage is provided between the scraping lip and the brush rod. The exhaust passage keeps the inner space and the outer space of the bottle body in a communicating state all the time. Therefore, when the brush rod breaks through the scraping lip and enters the inner space of the bottle body, the air in the inner space can be discharged from the exhaust passage in time, avoiding the increase in the air pressure in the inner space of the scraping lip caused by the entry of the brush rod and the brush head, and also avoiding the splash phenomenon of the cosmetic material due to the sudden change in the air pressure in the inner space of the scraping lip when the brush head is separated from the scraping lip.
[0018] (2) Since in this application, the exhaust passage is designed between the scraping lip and the brush rod instead of directly opening the exhaust passage on the scraping lip, the strength of the scraping lip is not affected, thus ensuring the scraping effect of the scraping lip. At the same time, the qualification rate of the inner plug formed by the integral mold is also improved, and the production cost of the inner plug is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment: As Figures 1-9 shown, a plug with a ventilation function is installed at the bottle mouth 510 of the bottle body 500. The plug includes a plug body 100. A scraping lip 200 is provided on the inner side wall of the plug body 100. A brush rod 400 is provided in the bottle body 500. A gap is formed between the scraping lip 200 and the brush rod 400 to form an exhaust passage 220. The exhaust passage 220 communicates with the inner space 540 and the outer space 550 of the scraping lip 200. The inner space 540 of the scraping lip 200 refers to the space inside the bottle body 500 that is separated by the scraping lip 200 and away from the bottle mouth 510. The outer space 550 of the scraping lip 200 refers to the space inside the bottle body 500 that is separated by the scraping lip 200 and close to the bottle mouth 510.
[0033] Optionally, the plug body 100 has a tubular structure with openings at both the upper and lower ends. As Figure 6As shown, the plug body 100 is installed at the bottle mouth 510 of the bottle body 500. The brush rod 400 passes through the plug body 100 and is placed inside the bottle body 500. Cosmetics, color cosmetics or skin care products can be stored inside the bottle body 500, such as mascara, liquid lipstick, lip gloss, nail polish, eyeshadow, etc. Users can apply makeup by dipping the brush head of the brush rod 400 into the makeup material in the makeup container. Before the brush rod 400 and the brush head are separated from the makeup container, the excess material needs to be scraped off by the scraping lip 200. Optionally, the plug body 100 is integrally injection molded with an elastic material. Optionally, the plug body 100 is made of NBR, that is, nitrile rubber.
[0034] After the brush rod 400, the plug body 100 and the bottle body 500 are assembled, as Figure 6 shown, the scraping lip 200 and the brush rod 400 divide the bottle body 500 into two closed spaces, the inner space 540 below the scraping lip 200 and the outer space 550 above the scraping lip 200. As Figure 2 shown, since there is a gap, namely the exhaust passage 220, between the scraping lip 200 and the brush rod, the inner space 540 and the outer space 550 are always in a communicating state. Therefore, when the brush rod 400 breaks through the scraping lip 200 and enters the inner space 540 of the bottle body 500, the air in the inner space 540 can be discharged from the exhaust passage 220 in time, avoiding the increase in air pressure in the inner space 540 of the scraping lip caused by the entry of the brush rod and the brush head, and also avoiding the splashing phenomenon of the cosmetic material due to the sudden change in air pressure in the inner space 540 of the scraping lip at the moment when the brush head is separated from the scraping lip.
[0035] The gap between the scraping lip 200 and the brush rod 400 means that some areas between the scraping lip 200 and the brush rod 400 are in mutual contact, and the remaining areas form a narrow gap, and the gap is the exhaust passage 220. In this way, on the premise of ensuring good scraping effect of the scraping lip, the inner space and the outer space can be ensured to communicate with each other. Since the exhaust passage is designed between the scraping lip and the brush rod in this application, rather than directly opening the exhaust passage on the scraping lip, the strength of the scraping lip will not be affected, thus ensuring the scraping effect of the scraping lip; at the same time, the qualification rate of the inner plug formed by the integral mold is also improved, and the production cost of the inner plug is reduced.
[0036] As Figure 2 and Figure 3 shown, the first end of the scraping lip 200 is fixedly connected to the inner wall of the bottle body 500, the second end of the scraping lip 200 extends radially inward along the plug body 100, and the second end of the scraping lip 200 encloses a scraping hole 210. The brush rod 400 is inserted into the scraping hole 210, and an exhaust passage 220 is formed between the brush rod 400 and the second end of the scraping lip 200.
[0037] In a possible implementation, the plug body 100 includes a first end and a second end of the plug body. The scraping lip 200 is located on the inner wall between the first end and the second end of the plug body 100, and the scraping lip 200 is close to the second end of the plug body 100. In another possible implementation, the scraping lip 200 is located on the inner wall of the second end of the plug body 100.
[0038] Optionally, the radial cross-section of the brush rod 400 is Pattern A, and the orthographic projection of the scraping hole 210 on the bottom 520 of the bottle body 500 is Pattern B, and the shapes of Pattern A and Pattern B are different. The brush rod 400 and the scraping hole 210 are designed with different shapes. In this way, after the brush rod 400 is inserted into the scraping hole 210, the second end of the brush rod 400 and the scraping lip 200 will not fit completely, thus forming an exhaust passage 220.
[0039] Optionally, Pattern A is at least one of a circle, an ellipse, and a polygon, and Pattern B is at least one of a circle, an ellipse, and a polygon. When Pattern A is a circle, Pattern B can be an ellipse or a polygon. When Pattern A is an ellipse, Pattern B can be a circle or a polygon. When Pattern A is a polygon, Pattern B can be a circle or an ellipse, etc. Thus, it is ensured that a narrow exhaust passage 220 can be formed between the brush rod 400 and the scraping lip 200.
[0040] In a possible implementation, Pattern A is a circle and Pattern B is a polygon, and the number of sides of the polygon is 3 to 12. That is, the brush rod 400 is designed as a cylindrical structure, which conforms to people's usage habits. The scraping hole 210 is designed as a polygon structure. After the brush rod 400 is inserted into the scraping hole 210, multiple exhaust passages 220 can be formed between the brush rod 400 and the scraping lip 200, and an exhaust passage can be formed at each included angle of the polygon and the brush rod 400.
[0041] As Figure 2 shown, Pattern A is a circle, Pattern B is an equilateral hexagon, the brush rod 400 and the plug body 100 are coaxially arranged, the diameter of Pattern A is D1, and the diameter of the inscribed circle of Pattern B is D2, and D1≥D2. Figure 2 The circle inside the hexagon in the figure is a schematic diagram of Pattern A. In this implementation, the brush rod 400 is designed as a cylindrical structure, the scraping hole 210 is designed as a hexagonal structure, and the diameter of the brush rod 400 is greater than or equal to the diameter of the inscribed circle of the hexagon. In this way, most areas between the brush rod 400 and the scraping lip 200 can be fitted together, ensuring the scraping effect of the scraping lip. And six exhaust passages 220 are provided between the brush rod 400 and the scraping lip 200 to ensure that the inner space 540 and the outer space 550 are always in a connected state. The scraping hole is designed as an equilateral hexagonal structure, which improves the yield rate of the inner plug in the integrated mold forming and ensures the strength of the scraping lip.
[0042] In a possible implementation, take any two points on the scraping lip 200. The thicknesses of the scraping lip 200 at the two points are T1 and T2 respectively, and the difference between T1 and T2 is less than Δ, where Δ is the tolerance. The specific value of Δ is determined according to the actual situations such as the size, material, precision requirements of the inner plug and the application scenario. Optionally, Δ is 0.1% to 5% of the average thickness of the scraping lip 200, which is convenient for the molding of the product.
[0043] In another possible implementation, take any two points A and B on the scraping lip 200. If the distance of point A from the second end of the scraping lip 200 is less than the distance of point B from the second end of the scraping lip 200, then the thickness of the scraping lip 200 at point A is less than the thickness of the scraping lip 200 at point B. As Figure 6 shown, the second end of the scraping lip 200 is inclined towards the bottom 520 side of the bottle body 500. That is, the thickness of the first end of the scraping lip 200 is the largest, and the thickness of the second end is the thinnest, and the scraping lip 200 is inclined towards the direction of the bottom 520, which can improve the scraping effect of the scraping lip.
[0044] As Figure 1 and Figure 2 shown, a convex edge 110 is formed by radially extending the first end of the plug body 100 outwards, and N spaced-apart stoppers 130 are formed by radially extending the outer side wall of the plug body 100 outwards. The N stoppers 130 are located at the same axial position of the plug body 100, where N is an integer and N≥2. As Figures 6-9 shown, the lower end surface of the convex edge 110 fits against the upper end surface of the bottle mouth 510, and the upper end surface of the stopper 130 fits against the lower surface of the shoulder of the bottle body 500. The inner plug is limited in the up and down directions by the convex edge 110 and the stopper 130, so as to prevent the up and down position of the inner plug from shifting when the brush head enters or is withdrawn from the bottle body. The stoppers 130 are designed as N, and there is a gap between adjacent stoppers 130. Compared with a whole circle of stoppers, when the inner plug is inserted into the bottle body, the stoppers 130 are more likely to deform due to extrusion, making it convenient to insert the inner plug into the bottle mouth 510 of the bottle body 500. As Figure 2 shown, there are four stoppers 130 provided on the plug body 100. Of course, three, six, eight, etc. can also be set. Optionally, the stopper 130 is close to the second end of the plug body 100.
[0045] As Figures 4-6As shown, the stopper 130 is provided with a first surface 131 and a second surface 132. The first surface 131 is arranged perpendicular to the axis of the plug body 100, and an obtuse angle a is formed between the second surface 132 and the axis of the plug body 100. The convex edge 110 fits against the bottle mouth 510 of the bottle body 500, and the first surface 131 fits against the shoulder of the bottle body 500. During assembly, the inclined second surface 132 of the stopper 130 is used as a guiding surface, which further improves the convenience of inserting the inner plug into the bottle body. After assembly, the vertical first surface 131 of the stopper 130 fits against the bottle shoulder of the bottle body 500, effectively preventing the inner plug from falling off.
[0046] As Figure 3 and Figure 4 shown, a circular boss 140 is formed by the inner side wall of the plug body 100 extending radially inward. The boss 140 is located on the side of the scraping lip 200 close to the bottle mouth 510 of the bottle body 500. As Figure 5 shown, the boss 140 is used to receive the pressing fixture 600. During assembly, the plug body 100 is pressed into the bottle body 500 by the pressing fixture 600 against the boss 140, so that the soft scraping lip does not directly contact the metal pressing fixture 600, ensuring the smooth assembly of the inner plug and reducing the risk of damage to the inner plug.
[0047] As Figures 6-9 shown, a cosmetic container includes an inner plug, a cap assembly 300, a brush rod 400 and a bottle body 500. The inner plug is installed at the bottle mouth 510 of the bottle body 500. The first end of the brush rod 400 is fixedly installed in the cap assembly 300, and the second end of the brush rod 400 is fixedly connected to the brush head. The cap assembly 300 is detachably covered on the bottle mouth 510 of the bottle body 500. The cap assembly 300 and the brush rod 400 are fixed together by means of snap connection, glue bonding, interference fit, etc. The brush rod 400 and the bottle body 500 are detachably connected together by means of screw connection, snap connection, interference fit, etc. Optionally, as Figure 6 、 Figure 8 and Figure 9 shown, an internal thread 410 is provided on the inner side wall of the brush rod 400, and an external thread 560 matching the internal thread 410 is provided on the outer side wall of the bottle mouth 510. The brush rod 400 and the bottle body 500 are fixed by screwing with the internal thread 410 and the external thread 560.
[0048] As Figure 9 shown, a convex rib 120 is provided on the outer side wall of the plug body 100, and a card slot 530 matching the convex rib 120 is provided on the inner side wall of the bottle body 500. The inner plug is further limited by the cooperation of the convex rib 120 and the card slot 530, and the inner plug can also play a positioning role during the assembly of the inner plug.
[0049] It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application shall be subject to the appended claims.
