Description

An instant mixing cap Technical Field

[0001] This utility model relates to the field of bottle caps, and more particularly to an instant mixing bottle cap. Background Technology

[0002] Instant mixing caps are bottle caps that pre-store powder in the cavity. Currently, instant mixing caps on the market dispense powder from the cavity in roughly three ways when opened: 1. The thin plastic area of ​​the lower cap is broken to form a discharge opening; 2. The upper and lower caps separate, breaking the interference seal and forming a discharge opening; 3. The sealing film is opened to form a discharge opening.

[0003] The above three methods address different issues. For example, in a design where the lower cover has a thin plastic area (usually PE), the mechanism breaks the thin plastic area of ​​the lower cover when the upper cover is opened, creating a material discharge opening. However, due to the thin area, the packaging has high permeability, resulting in a short product shelf life. Some packages also have the problem of the thin area being difficult to open. In a design where the upper and lower covers separate, disrupting the sealing effect to create a material discharge opening, the cover may not guarantee a tight seal. In a three-piece sealed film design, consumers typically rotate the upper cover counter-clockwise, causing the central cutting mechanism to rotate clockwise and move downwards, cutting the sealing film through the end cutting teeth to create a material discharge area. However, in this design, when storing powder, the powder can easily obstruct the mechanism's movement. Summary of the Invention

[0004] In view of the aforementioned deficiencies in the prior art, the technical problem to be solved by this invention is the high permeability, short shelf life, poor sealing, and the tendency of powder to obstruct the movement mechanism of existing instant mixing caps. Therefore, this invention provides an instant mixing cap that uses a structure with low packaging permeability, high sealing, and long shelf life, and makes the powder storage area independent of the movement mechanism that opens the sealing film, thus avoiding the problem of powder obstructing the movement mechanism.

[0005] To achieve the above objectives, this utility model provides an instant mixing cap, comprising an upper cap, a film-pushing device, and a lower cap. The film-pushing device is disposed between the upper cap and the lower cap, and is slidably connected to the interior of the lower cap. The upper part of the film-pushing device is connected to the upper cap, and a driving device is formed between the film-pushing device and the upper cap. The upper cap and the lower cap are threadedly connected. A sealing film is provided at the lower part of the lower cap. The closed cavity formed by the upper cap, the film-pushing device, the lower cap, and the sealing film is configured as a powder cavity.

[0006] Furthermore, a sealing device is provided on the outside of the film-pushing device to prevent powder from leaking into the drive mechanism between the film-pushing device and the top cover.

[0007] Furthermore, a second sealing device is provided between the top cover and the film-pushing device to further prevent powder leakage.

[0008] Furthermore, the upper cover includes an upper cover body, an upper cover drive post, and an upper cover inner plug. The upper cover drive post and the upper cover inner plug are disposed at the top of the upper cover body, and the upper cover inner plug is disposed between the side wall of the upper cover body and the upper cover drive post. A space for accommodating the film pushing device is formed between the upper cover inner plug and the upper cover drive post, and a space for accommodating the side wall of the lower cover is formed between the upper cover inner plug and the inner wall of the upper cover body. The upper cover inner plug is used for sealing the upper cover and the lower cover. The inner wall of the upper cover is provided with upper cover threads.

[0009] Furthermore, the upper cover also includes an upper cover drive column sealing ring, which is located on the inner side of the upper cover drive column, and the length of the upper cover drive sealing ring is longer than that of the upper cover drive column.

[0010] Furthermore, the top cover also includes an anti-theft ring, which is connected to the bottom break point of the side wall of the top cover.

[0011] Furthermore, the lower cap includes a lower cap bottle mouth body, a film pushing device fixing post, and a lower cap inner plug. The space formed by the lower cap bottle mouth body, the upper cap inner plug, and the inner wall of the upper cap body is sealed together. The lower cap bottle mouth body is provided with a lower cap bottle mouth thread that mates with the upper cap thread. The film pushing device fixing post is located on the inner wall of the lower cap bottle mouth body and is slidably connected to the film pushing device. The lower cap inner plug is located on the outer side of the lower end of the lower cap bottle mouth body.

[0012] Furthermore, the lower cap also includes a lower cap thread for connecting to the bottle body.

[0013] Furthermore, it also includes a lower cap fastening rib, which is used to securely connect to the bottle body.

[0014] Furthermore, the film-pushing device includes a film-pushing device body, a driven column, a film-pushing device track, and an outer sealing ring of the film-pushing device. The driven column is located on the inner wall of the film-pushing device body and cooperates with the upper cover drive column. The film-pushing device track cooperates with the film-pushing device fixing column, so that the film-pushing device rotates inside the lower cover bottle mouth body. The outer sealing ring of the film-pushing device is located on the lower outer wall of the film-pushing device body and maintains a sealed state with the inner wall of the lower cover bottle mouth body.

[0015] Furthermore, a film-pulling plate is provided at the lower part of the film-pushing device.

[0016] Furthermore, the film-pushing device also includes a film-pushing device driven column sealing ring, which cooperates with the upper cover drive column sealing ring and is arranged perpendicularly to the upper cover drive column sealing ring, further ensuring that the powder is stored in a relatively sealed area and preventing the powder from leaking into the drive device between the film-pushing device and the upper cover.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] In the following description, specific details, such as particular internal procedures and techniques, are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention may be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] As shown in Figures 1-7, this utility model provides an instant mixing bottle cap, including an upper cap 100, a film-pushing device 300, and a lower cap 200. The film-pushing device 300 is disposed between the upper cap 100 and the lower cap 200, and the interior of the film-pushing device 300 and the lower cap 200 are slidably connected. The upper part of the film-pushing device 300 is connected to the upper cap 100, but not fixedly, meaning that the film-pushing device 300 and the upper cap 100 can be separated. A driving device is formed between the film-pushing device and the upper cap to drive the film-pushing device to move up and down. The upper cap 100 and the lower cap are connected by a thread 206. A sealing film 208 is provided at the lower part of the lower cap 200. The closed cavity formed by the upper cap 100, the film-pushing device 300, the lower cap 200, and the sealing film 208 is a powder cavity. A sealing device 305 is provided on the outside of the film-pushing device to prevent powder from leaking into the driving device between the film-pushing device 300 and the upper cap 100. The sealing film includes, but is not limited to, commonly used aluminum film. Furthermore, a second sealing device is provided between the top cover and the film-pushing device to further prevent powder leakage.

[0031] The upper cover 100 includes an upper cover body, an upper cover drive post 101, and an upper cover inner plug 103. The upper cover drive post 101 and the upper cover inner plug 103 are located at the top of the upper cover body, and the upper cover inner plug 103 is located between the side wall of the upper cover body and the upper cover drive post 101. A space for accommodating the film pushing device 300 is formed between the upper cover inner plug 103 and the inner wall of the upper cover body, and a space for accommodating the side wall of the lower cover is formed between the upper cover inner plug 103 and the upper cover drive post 101. The inner wall of the upper cover 100 is provided with an upper cover thread 104. The upper cover inner plug 103 is used for sealing between the upper cover 100 and the lower cover 200. The upper cover 100 also includes an upper cover drive post sealing ring 102, which is located inside the upper cover drive post 101, and the length of the upper cover drive post sealing ring 102 is longer than that of the upper cover drive post 101.

[0032] The lower cap 200 includes a lower cap bottle mouth body 201, a film-pushing device fixing post 204, and a lower cap inner plug 205. The lower cap bottle mouth body 201 forms a sealed fit with the space formed by the upper cap inner plug 103 and the inner wall of the upper cap body. The lower cap bottle mouth body 201 is provided with a lower cap bottle mouth thread 202 that mates with the upper cap thread 104, so that the upper cap 100 and the lower cap bottle mouth body 201 are connected by threads. The film-pushing device fixing post 204 is disposed on the inner wall of the lower cap bottle mouth body 201 and is slidably connected to the film-pushing device 300. The lower cap inner plug 205 is disposed on the outer side of the lower end of the lower cap bottle mouth body 201. In this embodiment, the film-pushing device fixing post 204 is configured as a cylinder and fixed to the inner wall of the lower cap bottle mouth body.

[0033] The film-pushing device 300 includes a film-pushing device body, a driven column 301, a film-pushing device track 304, and a film-pushing device outer sealing ring 305. The driven column 301 is disposed on the inner wall of the film-pushing device body and cooperates with the upper cover drive column. The film-pushing device track 304 cooperates with the film-pushing device fixing column 204, allowing the film-pushing device 300 to rotate inside the lower cover bottle mouth body. The film-pushing device outer sealing ring 305 is disposed on the lower outer wall of the film-pushing device body and maintains a sealed state with the inner wall of the lower cover bottle mouth body 201. In this embodiment, the film-pushing device 300 is configured as a hollow, approximately cylindrical film-pushing device. The rotation direction of the film-pushing device track 304 is opposite to the direction of the upper cover thread 104, and the film-pushing device track 304 and the film-pushing device fixing column 204 are in sliding engagement. In this embodiment, the film-pushing device track 304 is provided with a blocking mechanism to ensure that the film-pushing device fixing column 204 slides within the film-pushing device track 304, thereby ensuring that the film-pushing device does not fall off.

[0034] The lower part of the film-pushing device 300 is provided with a film-pulling plate 307. The film-pushing device 300 also includes a film-pushing device driven column sealing ring 302, which cooperates with the upper cover drive column sealing ring 102 and is perpendicular to the upper cover drive column sealing ring 102, forming a second sealing device. The cooperation between the film-pushing device driven column sealing ring 302 and the upper cover drive column sealing ring prevents the powder inside the bottle cap from falling between the upper cover drive column and the film-pushing column driven column, ensuring smooth movement of the drive structure.

[0035] The cavity between the upper cap body and the film-pushing device forms a semi-closed chamber for placing powder. After the powder is placed, a sealing film is applied, sealing the semi-closed chamber into a closed chamber, thus pre-positioning the powder inside the cap. In use, the upper cap body is rotated counterclockwise. This causes the upper cap drive column inside the upper cap body to rotate counterclockwise, and the driven column of the film-pushing device, which cooperates with the upper cap drive column, also rotates counterclockwise. The upper cap body moves away from the lower cap bottle opening body along the upper cap thread direction, while the film-pushing device slides within its track via a fixed column inside the lower cap bottle opening body. Because the rotation direction of the film-pushing device track is opposite to the thread direction of the upper cap body, the film-pushing device slides downwards, gradually separating the upper cap body from the film-pushing device. The film-pushing device moves downwards, causing the film-pushing column 306 and the film-pulling plate 307 to pierce the sealing film, forming a discharge opening. Due to the design of the film-pushing track 304, the stroke of the film-pushing device can be controlled, thus ensuring that the sealing film forms a discharge opening but does not completely detach. The film-pushing column 306 is used to tear / push open the sealing ring, and the film-pulling plate 307 is used to increase the opening angle of the sealing film, facilitating material discharge. In this embodiment, because a sealing device is provided between the upper cover driving column and the driven column of the film-pushing device, and a sealing device is provided between the film-pushing device and the interior of the lower cover bottle mouth body, the powder stored in the cavity will not permeate between the driving and driven mechanisms, and will not hinder the movement of the driving device. In this embodiment of the invention, the sealing film is preferably an aluminum film. Aluminum film, as a sealing film, has low permeability and good sealing and stability, resulting in a long shelf life for the product. At the same time, aluminum film is easy to open.

[0036] In another preferred embodiment of this utility model, the upper cover 100 further includes an upper cover anti-theft ring 105, which is connected to the bottom end of the upper cover side wall at a break point. The lower cover bottle mouth body 201 also includes a lower cover bottle mouth anti-theft ring 203. The lower cover bottle mouth anti-theft ring 203 and the upper cover anti-theft ring 105 cooperate with each other to ensure that the instant mixing bottle cap is sealed when it leaves the factory. When the upper cover body is rotated, the upper cover anti-theft ring remains stationary under the action of the lower cover bottle mouth anti-theft ring, and the break point connection between the upper cover body and the upper cover anti-theft ring is broken.

[0037] In another preferred embodiment of the present invention, the lower cover further includes a lower cover thread 206, which is used to connect with the bottle body, so that the bottle cap can be applied to different bottle bodies.

[0038] In another preferred embodiment of the present invention, a lower cover fastening rib 207 is further included, which is used to securely connect with the bottle body.

[0039] This utility model provides an instant mixing bottle cap with low packaging permeability, high density, and long shelf life. In addition, due to the presence of multiple sealing structures in the structure, the powder will not obstruct the movement of the film pushing device, thereby improving the efficiency of instant mixing.

[0040] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
