Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap technology, and in particular to an adjustable flow bottle cap. Background Technology
[0002] In daily life, many bottled liquids (such as cooking oil, soy sauce, vinegar, condiments, and detergents) are sealed with caps. The most common caps, such as simple screw caps or flip caps, have a fixed orifice size. When users need to precisely control the flow rate of the liquid, such as adding a few drops of sesame oil while cooking or using concentrated dish soap, this fixed orifice design becomes very inconvenient and can easily lead to excessive flow and waste.
[0003] To address this issue, some bottle caps with flow adjustment functions have appeared on the market. However, existing adjustable flow bottle caps generally suffer from one or more of the following drawbacks:
[0004] Complex structure and poor sealing: Existing designs typically use an external rotating ring or slider to move the internal baffle, exposing the adjustment mechanism. This structure not only has numerous parts, complex assembly, and high production costs, but the gaps formed between the external moving parts and the cap are also prone to accumulating dirt and grime. More importantly, these gaps become potential leakage points, making it difficult to guarantee the sealing performance when the bottle is tipped over or subjected to external impact.
[0005] Difficult to clean and poses hygiene risks: To achieve flow regulation, these bottle caps often have complex flow channels and non-removable layered structures inside. Liquids (especially viscous liquids such as oil and sugar) can easily remain in the gaps of these structures after use, making thorough cleaning difficult. Over time, the residue may deteriorate and breed bacteria, posing serious food safety or hygiene risks.
[0006] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content
[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a bottle cap that is simple in structure, reliable in sealing, easy to disassemble to achieve thorough cleaning, and hygienic and convenient in operation.
[0008] This utility model is achieved through the following technical solution:
[0009] To solve the above-mentioned technical problems, this utility model provides an adjustable flow bottle cap, including a cap body. A baffle is provided in the inner cavity of the cap body. A central post extending upwards integrally is provided at the center of the upper surface of the baffle, and at least one first through hole is formed on the baffle. A rotatable rotating cap is detachably fitted onto the central post. A sealing plate is provided at the lower end of the rotating cap. The sealing plate is in contact with the upper surface of the baffle, and at least one second through hole selectively communicating with the first through hole is formed at a corresponding position on the sealing plate. By rotating the rotating cap, the sealing plate can be rotated relative to the baffle, thereby aligning or interleaving the second through hole with the first through hole, thus regulating the flow rate through the bottle cap.
[0010] To further address the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap in which a limiting protrusion is provided on the inner wall of the cap body above the baffle, and an installation groove is formed between the limiting protrusion and the baffle to accommodate and limit the edge of the sealing plate.
[0011] In order to further solve the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap, wherein the upper opening of the cap body is provided with an openable and closable top cover, and in the closed state, the top cover completely covers the rotating cap inside the cap body.
[0012] To further address the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap in which, when the top cap is closed, the inner top surface of the top cap abuts against the top of the rotating cap, thereby pressing the sealing plate of the rotating cap toward the baffle.
[0013] In order to further solve the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap, wherein the top cover is a flip-top structure, one side of the top cover is integrally connected to the upper edge of the cap body through a flexible connecting part, and a snap-fit structure for fastening and fixing the top cover is also provided between the top cover and the cap body.
[0014] To further address the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap in which the upper part of the rotating cap protrudes from the upper edge of the cap body.
[0015] In order to further solve the technical problem to be solved by this utility model, the adjustable flow bottle cap provided by this utility model has anti-slip texture on the outer peripheral wall or top surface of the upper end of the rotating cap.
[0016] To further address the technical problem to be solved by this utility model, this utility model provides an adjustable flow bottle cap in which a plurality of first through holes are provided on the baffle plate in a circular array; and a plurality of second through holes are correspondingly provided on the sealing plate in a circular array.
[0017] To further address the technical problems to be solved by this utility model, this utility model provides an adjustable flow bottle cap, wherein the lower end of the cap body is provided with an internal thread for connecting with the bottle mouth.
[0018] Compared with the prior art, the present invention has the following advantages:
[0019] 1. Built-in adjustment, reliable structure, and excellent sealing. This utility model integrates the rotating cap and flow regulation mechanism within the cover body, which is then covered by the top cover. This built-in design protects moving parts from external impacts and contamination, resulting in a more compact and reliable structure. Simultaneously, when the top cover is closed, additional axial pressure is applied to the rotating cap, ensuring a tighter fit between the sealing plate and the baffle. Combined with the limiting mounting groove structure, this provides double leak protection, significantly improving sealing performance under shaking, transportation, or tilting conditions.
[0020] 2. Easy disassembly and assembly, thorough cleaning, hygienic and safe. The rotating cap of this invention is detachably mounted on the central post of the baffle via a simple shaft-hole connection. When cleaning is required, the user simply pulls upwards to easily remove the rotating cap, completely separating the cap, baffle, and rotating cap. This design completely eliminates the cleaning dead zones caused by the complex structure of traditional regulating bottle caps, facilitating thorough rinsing with water and effectively preventing the accumulation of oil, residue, and bacterial growth. It is particularly suitable for applications with high hygiene requirements, such as food and condiments.
[0021] 3. Intuitive operation, hygienic, and superior user experience. Users can easily adjust the flow rate and disassemble / install the device by simply pinching the handle at the top of the rotating cap, eliminating the need for fingers to touch the sealing plate or baffle area that may contain residual liquid. This "clean operation" design avoids soiling hands and prevents cross-contamination of the bottle opening area with hand dirt. Combined with the anti-slip textured design on the top of the rotating cap, the adjustment process is not only hygienic but also precise and effortless, significantly improving the user experience. Attached Figure Description
[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:
[0023] Figure 1 This is an exploded view of the present invention;
[0024] Figure 2 This is a cross-sectional view of the present invention. Detailed Implementation
[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Please see Figure 1 and Figure 2 This embodiment provides an adjustable flow bottle cap that is compact, reliably sealed, and easy to clean. The bottle cap mainly includes a cap body 1, a baffle 2 fixed or integrally connected inside the cap body 1, a rotating cap 4 rotatably mounted on the baffle 2, and a top cover 6 for opening and closing.
[0027] Specifically, the cap body 1 is the main structure of the entire bottle cap, and its lower end is provided with an internal thread 13. This internal thread 13 is used to mate with the external thread of the bottle mouth, thereby reliably installing the entire bottle cap onto the bottle body. Inside the cavity of the cap body 1, a disc-shaped baffle 2 is fixedly installed. This baffle 2 divides the cavity of the cap body 1 into upper and lower parts, serving both a load-bearing and separating function.
[0028] A central pillar 3 extends integrally upward from the center of the upper surface of the baffle 2. This central pillar 3 serves as the rotation axis, providing stable rotational support for the rotating cap 4. Multiple (e.g., four, as shown in the figure) first through holes 21 are arranged in a circular array around the central pillar 3 on the surface of the baffle 2. These first through holes 21 serve as fixed channels for liquid to flow out of the bottle.
[0029] The rotating cap 4 is the core moving component for flow regulation. It is detachably mounted on the central column 3. This "sleeving" installation method is simple in structure and makes it very convenient for users to simply pull the rotating cap 4 upwards and remove it from the central column 3 when thorough cleaning is required, achieving thorough cleaning of all components and effectively avoiding hygiene hazards.
[0030] The rotating cap 4 has a sealing plate 5 at its lower part, and the lower surface of the sealing plate 5 is smoothly attached to the upper surface of the baffle 2. Multiple second through holes 51, corresponding in number, shape, and position to the first through holes 21, are provided on the sealing plate 5. By pinching and rotating the rotating cap 4, the sealing plate 5 rotates relative to the fixed baffle 2. When the second through holes 51 are fully aligned with the first through holes 21, the flow channel is fully open, and the flow rate reaches its maximum. When the second through holes 51 and the first through holes 21 partially intersect, the cross-sectional area of the flow channel decreases, and the flow rate decreases accordingly. When the second through holes 51 and the first through holes 21 are completely misaligned, the first through holes 21 are completely blocked by the solid part of the sealing plate 5, the flow channel is closed, and a zero flow or sealed state is achieved. Users can adjust the rotation angle arbitrarily according to their needs to obtain the required precise flow rate.
[0031] To ensure a more stable installation and rotation of the rotating cap 4, in this embodiment, a limiting protrusion 11 is provided on the inner wall of the cover 1, above the baffle 2. This limiting protrusion 11 naturally forms an installation groove 12 between itself and the upper surface of the baffle 2. The edge of the sealing plate 5 is precisely accommodated within this installation groove 12. This design not only facilitates the precise installation of the rotating cap 4 but also prevents it from shaking or tilting during rotation, ensuring that the sealing plate 5 and the baffle 2 remain stably fitted, thus improving the smoothness of adjustment and the reliability of the seal.
[0032] To enhance the user experience, the upper part of the rotating cap 4 in this embodiment protrudes beyond the upper edge of the cover 1. Additionally, several anti-slip textures 41 are provided on its outer peripheral wall or top surface. This design allows users to easily identify and access the operating components and increases the friction between the fingers and the rotating cap 4, enabling easy and precise rotation even when the user's hands are wet or oily.
[0033] In this embodiment, a top cover 6 is also provided at the upper end of the cover body 1. This top cover 6 is a flip-top structure, with one side integrally connected to the upper edge of the cover body 1 via a flexible connecting part 61, achieving a flip-top opening and closing mechanism that is not easily lost. When it is not necessary to pour out liquid, the top cover 6 can be closed. It is worth mentioning that the top cover 6 has a dual function:
[0034] First, it covers and seals. It completely covers the entire flow regulating mechanism (i.e., the rotating cap 4) inside the cover body 1, preventing external contaminants such as dust from entering and keeping the interior clean.
[0035] Second, auxiliary compression. When the top cap 6 is closed, its inner top surface abuts against the top of the rotating cap 4. This abutting action applies a continuous, slight axial pressure to the rotating cap 4, making the sealing plate 5 below it fit more tightly against the baffle 2. This design further enhances the sealing performance when the flow channel is closed, effectively preventing leakage of internal liquid when the bottle is violently shaken or accidentally inverted.
[0036] To ensure the top cover 6 can be securely closed, a locking structure is provided between the top cover 6 and the cover body 1. A preferred locking structure is that the upper edge of the cover body 1 is folded outward and slightly bent downward to form a spout that also serves as a liquid outlet guide. The top cover 6 is correspondingly provided with an outer ring and an inner ring. When closed, its inner ring can form a tight fit or a slight interference fit with the inner wall of the opening at the upper end of the cover body 1, while its outer ring extends downward to cover the outer edge of the spout, thereby achieving a secure latch.
[0037] Summary of working principle:
[0038] In use, first tighten the cap onto the bottle opening using the internal thread 13. Flip up the top cover 6 to expose the internal rotating cap 4. By pinching and rotating the rotating cap 4, adjust the alignment of the second through hole 51 with the first through hole 21 to set the desired liquid flow rate. Tilt the bottle to pour out the liquid. After use, rotate the rotating cap 4 to the fully closed position, then snap the top cover 6 down; the locking structure ensures a tight seal. When cleaning is required, open the top cover 6 and pull the rotating cap 4 vertically upwards to separate it from the cap / baffle assembly. Rinse separately, let dry, and then reattach. The whole process is simple and quick.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
