Cosmetic container

Abstract

The present application relates to the technical field of cosmetics, and provides a cosmetic container. During use, a rotary cap is rotated and then drives a connecting transmission member to rotate together; the connecting transmission member drives a helical member to rotate; a base body is fixed on a hose body; the base body remains stationary, and the helical member moves upwards relative to the base body by means of rotation, such that a base channel is opened, and the rotary cap is separated from the hose body; cosmetic contents in the hose body flows into a flow channel via the base channel, and overflows via an application member during normal use; and after use, the rotary cap is screwed onto the hose body, the rotary cap rotates to drive the connecting transmission member and the helical member to rotate together, and the helical member moves downwards to block the base channel, so as to prevent the cosmetic contents from flowing out of the hose body. Thus, without using a metal spring, an internal channel is also opened whilst the rotary cap is unscrewed, and the contents can be normally used; and when the rotary cap is screwed tight, the internal channel is closed, thereby preventing the contents from overflowing.

[0002] This application claims priority to Chinese Patent Application No. 2024226443151, filed on October 30, 2024, entitled "Cosmetic Containers", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of cosmetic technology, and in particular to a cosmetic container. Background Technology

[0004] Traditional hose cap designs often employ a spring structure to automatically lift the sponge head and automatically close the channel, optimizing the user experience and efficiency during liquid delivery. This design uses the elastic force provided by an internal spring to keep the sponge head in a closed state when the cap is not turned, preventing external impurities from entering the hose and thus protecting its cleanliness and flowability. When the user turns off the cap, the spring force lifts the sponge head, opening the channel and allowing the liquid to flow out smoothly. This mechanism simplifies the user's operation and improves product convenience.

[0005] However, while conventional spring structures achieve the aforementioned functions, they also have certain limitations and potential problems. The most significant issue lies in the non-removability of the spring itself or the stringent requirements for material selection. The spring is typically embedded inside the hose head, becoming a fixed component in the structure. This design means that once the spring wears out, is damaged, or needs replacement (e.g., due to material aging, corrosion, or other reasons), the entire hose head, or at least the component involving the spring, may need to be replaced. In such cases, the overall replacement cost is high, and it poses challenges to environmental and resource management.

[0006] Furthermore, reliance on springs can also affect the design flexibility and customization of a product. To ensure the stability and durability of the spring's elasticity, manufacturers often need to select specific materials and processing techniques, which not only increases manufacturing costs but may also limit the product's scalability and adaptability to different application scenarios.

[0007] In summary, while the spring structure effectively enables the automatic opening and closing of the sponge head, it also introduces technical challenges such as difficulty in removing the spring, high spring maintenance costs, and limited design flexibility. These issues are among the key factors that hose head designers need to consider when seeking improvements and innovations.

[0053] The cosmetic container provided in this application, when in use, involves rotating the cap, which in turn rotates the connecting transmission component, which in turn rotates the spiral component. The base body is fixed to the tube body and remains stationary. The spiral component moves upward relative to the base body through rotation, opening the base channel and separating the cap from the tube body. The cosmetic contents inside the tube body flow into the flow channel through the base channel and overflow through the application component for normal use. After use, the cap is screwed back onto the tube body. The rotation of the cap causes the connecting transmission component and the spiral component to rotate together, and the spiral component moves downward, blocking the base channel and preventing the cosmetic contents inside the tube body from flowing out. The overall structure achieves the goal of opening the internal channel when the cap is unscrewed, allowing the contents to be used normally, and closing the internal channel when the cap is tightened, preventing the contents from overflowing.

[0085] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0086] The cosmetic container provided in this application includes: a screw cap 100, an application component, a connecting transmission component, a spiral component 300, a base body 400, and a tube body 500; the screw cap 100 is threadedly connected to the tube body 500; the connecting transmission component is connected to the application component, and the inner wall of the screw cap 100 can abut against the outer wall of the connecting transmission component so that the connecting transmission component can rotate together when the screw cap 100 rotates; the base body 400 is connected to the tube body 500, and the end of the base body 400 extends into the tube body 500 through the bottle opening of the tube body 500, and the tube body 500 contains... The product contains cosmetic contents; a spiral member 300 extends into the base body 400 and is threadedly connected to the base body 400; the spiral member 300 is connected to a connecting transmission member; the middle portion of the spiral member 300 and the middle portion of the connecting transmission member form a flow channel communicating with the application member; the end of the base body 400 extending into the tube body 500 has a base channel 460; the spiral member 300 is configured to rotate together with the connecting transmission member so that the spiral member 300 can move relative to the base body 400 to control the opening and closing of the base channel 460 and the flow channel.

[0087] Regarding the shape and structure of the screw cap 100, specifically:

[0088] As shown in Figure 3, the inner wall of the cap 100 is formed with cap threads 120, which are threaded to the bottle mouth of the hose body 500. The cap 100 is screwed onto the hose body 500 by screwing. A protrusion 110 is formed extending inward on the inner wall of the cap 100. The protrusion 110 is configured to fit tightly against the outer wall of the connecting transmission component, so that the cap 100 rotates together with the connecting transmission component through friction.

[0089] The inner wall of the screw cap 100 has a stepped surface 130, and the outer wall of the screw member 300 extends outward to form a pressing surface 380. The stepped surface 130 can abut against the pressing surface 380, thereby enabling the screw cap 100 to push the screw member 300 downward.

[0090] Regarding the structure and shape of the helical component 300, specifically:

[0091] The spiral component 300 has a spiral channel 370 that is formed by the middle part of the spiral component 300 and the opening at the bottom of the spiral component 300, which facilitates the overflow of cosmetic contents. A spiral thread 340 is provided on the outside of the spiral component 300, and the spiral thread 340 enables the spiral component 300 to be threadedly connected to the base body 400. A spiral assembly hole 310 is provided on the top of the spiral component 300, and the spiral assembly hole 310 is configured to connect the extension of the transmission component.

[0092] In an optional embodiment, the outer wall of the spiral member 300 is provided with a spiral limiting buckle 330; the inner wall of the base body 400 is provided with a base limiting buckle 410; the spiral limiting buckle 330 can abut against the base limiting buckle 410 to limit the movement distance of the spiral member 300 in the base body 400 and prevent the spiral member 300 from extending out of the base body 400.

[0093] The outer wall of the spiral component 300 is provided with a spiral fastener 320. Specifically, the spiral fastener 320 is a protruding structure extending outward from the outer wall of the spiral component 300. The spiral fastener 320 is configured to connect with the connecting transmission component, and the spiral component 300 and the connecting transmission component are connected into an integral structure by means of the spiral fastener 320.

[0094] In an optional embodiment, a spiral sealing part 350 is provided on the outer bottom of the spiral member 300, and the spiral sealing part 350 is sealed to the inner wall of the base body 400; a sealing protrusion 360 is provided at the middle of the bottom end of the spiral member 300, and the sealing protrusion 360 can extend into the base channel 460 to block the base channel 460; the inner wall of the cap 100 is provided with a stepped surface 130, and the outer wall of the spiral member 300 extends outward to form a pressing surface 380, and the stepped surface 130 can abut against the pressing surface 380 so that the cap 100 can push the spiral member 300 to extend the sealing protrusion 360 into the base channel 460.

[0095] Regarding the shape and structure of the base body 400, specifically:

[0096] As shown in Figures 6 and 7, the inner wall of the base body 400 extends inward to form a base limiting buckle 410. The base limiting buckle 410 can abut against the spiral limiting buckle 330 to limit the movement distance of the spiral component 300. The outer wall of the base body 400 is provided with a base anti-rotation groove 420. The base anti-rotation groove 420 is formed by the gap between two adjacent protrusions. By inserting the base anti-rotation groove 420 into the multiple slots formed on the inner wall of the hose body 500, the base body 400 can be snapped onto the hose body 500, thereby limiting the rotation of the base body 400.

[0097] The inner wall of the base body 400 is formed with base threads 430, which cooperate with the spiral threads 340 on the spiral component 300 to realize the threaded connection between the base body 400 and the spiral component 300.

[0098] The inner wall of the base body 400 has a base first sealing surface 440, which is located below the base thread 430. The base first sealing surface 440 is tightly fitted with the spiral sealing part 350 to form a seal, preventing the contents of the cosmetic from flowing out from the gap between the base first sealing surface 440 and the spiral sealing part 350, and ensuring that the flow direction of the contents of the cosmetic is correct.

[0099] A second sealing surface 450 is provided on the inner wall of the base channel 460. The second sealing surface 450 can fit tightly with the sealing protrusion 360 on the spiral component 300 to form a seal, ensuring that when the sealing protrusion 360 extends into the base channel 460, the sealing protrusion 360 seals the base channel 460 and blocks the base channel 460, preventing the cosmetic contents in the tube body 500 from flowing out of the base channel 460.

[0100] The cosmetic container provided in this application, when in use, involves rotating the cap 100, which in turn rotates the connecting transmission component, which in turn rotates the spiral component 300. The base body 400 is fixed on the tube body 500 and remains stationary. The spiral component 300 moves upward relative to the base body 400 through rotation, opening the base channel 460 and separating the cap 100 from the tube body 500. The cosmetic contents inside the tube body 500 flow into the flow channel through the base channel 460 and overflow through the application component for normal use. After use, the cap 100 is screwed back onto the tube body 500. The rotation of the cap 100 causes the connecting transmission component and the spiral component 300 to rotate together, and the spiral component 300 moves downward, blocking the base channel 460 to prevent the cosmetic contents inside the tube body 500 from flowing out. The overall structure achieves the goal of opening the internal channel when the cap 100 is unscrewed, allowing the contents to be used normally, without the use of a metal spring. When the cap 100 is tightened, the internal channel closes, preventing the contents from overflowing.

[0101] The following describes various embodiments. It should be noted that the following embodiments differ only in the structure of the applicator and the connecting transmission component. The cap 100, the base body 400, the spiral component 300, and the hose body 500 all have the same structure. Therefore, the following embodiments only describe the specific structure of the applicator and the connecting transmission component.

[0102] As shown in Figures 1, 2, 3, 4, 5, 6, 7, and 8, the application component is a brush head 610, and the connecting transmission component is an inner plug 210. The top of the inner plug 210 is provided with an inner plug assembly hole 211. One end of the brush head 610 extends into the inner plug assembly hole 211, and the brush head 610 and the inner plug 210 are connected to each other.

[0103] The top end of the spiral member 300 extends into the inner plug 210, and the spiral member 300 and the inner plug 210 are connected to each other. Specifically, the middle part of the inner plug 210 has an inner plug lower post 214, which extends into the spiral member 300. There is a certain gap between the outer wall of the inner plug 210 and the inner plug lower post 214, and the top end of the spiral member 300 can extend into this gap. An inner plug snap position 213 is formed on the inner side of the outer wall of the inner plug 210. The inner plug snap position 213 and the spiral snap position 320 are engaged with each other, so that the inner plug 210 and the spiral member 300 are assembled into an integral structure. An inner plug channel 215 is formed through the middle part of the inner plug 210, and the protrusion 110 can fit tightly with the inner plug side 212, thereby driving the inner plug 210 and the screw cap 100 to rotate together through friction.

[0104] Unscrew the cap 100 counterclockwise. The friction between the protrusion 110 and the inner plug side 212 causes the inner plug 210 to rotate. The inner plug 210 then rotates the spiral component 300. The base body 400, being engaged with the tube body 500, remains stationary. Under the influence of mutual forces, the spiral component 300 slowly rotates upwards. When the spiral component 300 reaches a specific position, the spiral limit buckle 330 and the base limit buckle 410 abut against each other, preventing the spiral component 300 from continuing to rotate upwards. Therefore, the base channel 460 opens, the base first sealing surface 440 and the spiral sealing part 350 remain sealed, the cap 100 separates from the tube body 500, and the cosmetic contents overflow through the base channel 460, spiral channel 370, inner plug channel 215, and brush head 610.

[0105] After use, rotate the cap 100 clockwise. The cap 100 is screwed into the hose body 500. When it is screwed to a specific position, the protrusion 110 contacts the inner plug side 212. Continue to rotate the cap 100. The cap 100 and the inner plug side 212 generate friction. When the friction between the cap 100 and the inner plug side 212 is greater than the friction between the spiral thread 340 and the base thread 430, the cap 100 drives the inner plug 210 to rotate clockwise. The inner plug 210 drives the spiral component 300 to rotate. The base body 400 remains stationary because it is engaged with the hose body 500. Under the action of mutual forces, the spiral component 300 will slowly rotate downward. The second sealing surface 450 of the base and the sealing protrusion 360 on the spiral component 300 slowly close, while the first sealing surface 440 of the base and the spiral sealing part 350 remain sealed. When the second sealing position of the base contacts the sealing protrusion 360, the spiral component 300 stops rotating downward. At this time, the cap 100 continues to rotate, and the stepped surface 130 inside the cap 100 contacts the pressing surface 380. The cap 100 continues to rotate to the bottom, and the stepped surface 130 pushes the pressing surface 380, making the spiral component 300 completely fit with the base body 400. The sealing protrusion 360 and the second sealing surface 450 of the base are completely fitted together, maintaining an airtight seal and preventing the contents from flowing out.

[0106] As shown in Figures 9, 10, 11, and 12, the application component is configured as a TPE (Thermoplastic Elastomer) head 620. The TPE head 620 has an overflow channel through which the cosmetic contents can flow out. The connecting transmission component includes an inner plug 210 and a shoulder sleeve 220. The TPE head 620 is connected to the top of the inner plug 210, and the bottom end of the inner plug 210 extends into the spiral component 300, and the inner plug 210 and the spiral component 300 are interconnected. The inner wall of the shoulder sleeve 220 is interconnected with the spiral component 300. The protrusion 110 can fit tightly against the outer wall of the shoulder sleeve 220.

[0107] Specifically, the bottom of the inner plug 210 is an inner plug lower post 214, which extends into the spiral component 300. The middle of the inner plug 210 forms an inner plug channel 215. The outer wall of the inner plug 210 is provided with an inner plug fastener 213, which is connected to the second fastener 223 of the shoulder sleeve on the inner wall of the shoulder sleeve 220, so that the inner plug 210 and the shoulder sleeve 220 are assembled into a whole structure. The inner wall of the shoulder sleeve 220 is provided with a first fastener 222, which is connected to the spiral fastener 320, so that the shoulder sleeve 220 and the spiral component 300 are assembled into a whole structure, realizing the assembly of the inner plug 210, the shoulder sleeve 220 and the spiral component 300 into a whole.

[0108] The usage method is the same as that in the above embodiment.
