Description

Technical Field

[0001] This utility model specifically relates to a pressable storage bottle cap. Background Technology

[0002] Currently, most beverage bottles on the market are equipped with caps, allowing consumers to drink directly after purchase simply by unscrewing the cap. However, with the continuous development of functional beverages and ready-to-drink prepared beverages, some drinks require the addition of auxiliary ingredients such as tea powder, sugar powder, flavoring agents, and nutritional additives before consumption to meet different tastes or health needs. To achieve long-term preservation and immediate preparation of beverages, the traditional single-liquid storage mode is no longer sufficient to meet market demands, thus giving rise to the development of "dry and wet separation" packaging technology. Therefore, the inventor previously developed a detachable bottle cap product, referring to its applied Chinese utility model patent (application number: CN202322835761.6, title: A detachable bottle cap easy-to-unseal structure). This type of bottle cap typically consists of a cap base and a flexible pressing component, which together form a sealed storage cavity. The pressing component is equipped with a top pressure column, used to pierce the thin-walled structure at the bottom of the storage cavity when pressed, thereby releasing the material. Although this structure simplifies the number of components and improves sealing performance, new technical challenges have emerged in practical applications: Since the pressing components are mostly integrally molded soft structures, uneven local deformation easily occurs during pressing, causing the pressure column to tilt and press down. This not only increases puncture resistance but may also lead to incomplete cracking of the thin-walled structure, jamming of the pressure column, or even structural damage, seriously affecting reliability and product lifespan. Furthermore, the small pressing area and unreasonable shape result in poor comfort and difficulty in applying force when pressing with fingers, making it particularly unfriendly to children or elderly users. This invention addresses these shortcomings. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressable storage bottle cap that improves structural stability, ease of operation, and safety.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a pressable storage bottle cap, including a bottle cap base and a pressing component connected to the bottle cap base. The bottle cap base has a storage cavity with an open top. The pressing component has a vertically arranged top pressing column and a deformable cover plate arranged around the middle of the top pressing column. The deformable cover plate is connected to the bottle cap base around its four edges and seals the opening of the storage cavity. The deformable cover plate is a deformable structure made of soft material. The bottom of the storage cavity is composed of a thin-walled base plate. The lower end of the top pressing column has a pointed part for piercing the thin-walled base plate. The upper end of the top pressing column has a pressing disc that expands outwards for manual pressing.

[0006] As described above, the easy-to-press storage bottle cap has a protective cover connected to the top of the cap seat, and the pressing plate is located inside the protective cover.

[0007] As described above, the easy-to-press storage bottle cap has a support ring at the bottom of the pressing plate, with the top of the support ring connected to the pressing plate and the bottom of the support ring connected to the deformable cover plate.

[0008] As described above, in the easy-to-press storage bottle cap, the support ring gradually tilts outward from the pressing plate to the deformable cap plate.

[0009] As described above, the easy-to-press storage bottle cap has a disc-shaped pressing plate.

[0010] As described above, the easy-to-press storage bottle cap has a pressing plate with a concave spherical arc surface on the upper surface.

[0011] As described above, the easy-to-press storage bottle cap includes a deformation ring portion located around the top pressure post and bent, and a connecting ring portion connected to the periphery of the deformation ring portion and used to connect to the bottle cap seat. The bottle cap seat has an annular mounting surface around the opening of the storage cavity that matches the shape of the connecting ring portion.

[0012] As described above, the easy-to-press storage bottle cap has a connecting ring connected to the annular mounting surface via a plastic hot-pressing process. The bottom surface of the connecting ring has a downward-protruding connecting rib for hot-melting, and the annular mounting surface has a mounting ring groove for accommodating the connecting rib.

[0013] As described above, the easy-to-press storage bottle cap also has a sealing ring located at the bottom of the connecting ring portion, with the outer wall of the sealing ring abutting against the inner wall of the storage cavity.

[0014] As described above, the easy-to-press storage bottle cap has a concave arc ring surface in the middle of the cap seat surrounding its side wall.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. Significantly improved ease of operation and pressing comfort: By optimizing the design of the pressing components, including but not limited to using a spherical arc pressing disc with a concave or convex center and adding a support ring to evenly distribute pressure, not only is the comfort of pressing improved, but the pressing pressure is also ensured to be evenly distributed, avoiding displacement or damage to the top pressure column due to localized stress concentration. This design allows both adults and children to easily and accurately complete the material release operation.

[0017] 2. It boasts superior sealing performance and a stable, reliable structure. A hot-pressing process securely connects the deformable cap to the bottle cap holder, and a sealing ring further enhances the sealing effect, effectively preventing moisture absorption or leakage. Furthermore, the tear groove design on the thin-walled base plate ensures controllability and consistency in the puncture process, reducing unnecessary fragmentation and ensuring smooth entry of the material into the bottle for mixing with the beverage, thus improving overall safety and reliability.

[0018] 3. Highly versatile and adaptable, offering a superior user experience, this bottle cap can store various types of powdered materials (such as tea powder, sugar powder, and seasonings) to meet the personalized needs of different consumers. Furthermore, its polygonal or multi-shaped pressing plate design enhances the product's competitive advantage and provides users with more tactile feedback options. The concave arc design on the outer side of the cap holder greatly facilitates the removal of the protective cap, maintaining good grip and ease of operation, especially when hands are wet or gloves are worn, thus comprehensively improving the user experience.

[0032] The utility model will be further described below with reference to the accompanying drawings:

[0033] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0034] Example 1

[0035] This embodiment describes a press-type storage bottle cap, such as... Figure 1 As shown, this type of bottle cap is used to connect to the bottle opening A1 of a beverage bottle A. Its structure includes a cap holder 1 and a pressing member 2 connected to its top. The cap holder 1 has an open-top storage cavity 10. The pressing member 2 seals the opening of the storage cavity 10, forming a sealed space with the inner wall of the storage cavity 10 for storing materials, thus creating a complete storage space. During the manufacturing process, the required materials are first filled into the storage cavity 10, and then the pressing member 2 is assembled onto the cap holder 1, so that the storage cavity 10 and the pressing member 2 together constitute a closed storage space. When the bottle cap is installed on the beverage bottle A, the storage space is located directly above the bottle opening A1, facilitating the direct flow of material into the bottle after release, enabling rapid mixing with the beverage. In this embodiment, the stored material is pre-made tea powder; however, it can also be replaced with other soluble or miscible powdered materials such as sugar powder, seasonings, and nutritional additives, depending on actual needs.

[0036] like Figures 2 to 5As shown, the structure includes a bottle cap holder 1 and a pressing member 2 fixedly connected to it. The bottle cap holder 1 has a storage cavity 10 with an open top. The pressing member 2 includes a vertically arranged top pressing column 21 and a deformable cover plate 22 arranged around the middle of the top pressing column 21. The four edges of the deformable cover plate 22 are fixedly connected to the bottle cap holder 1, completely sealing the opening of the storage cavity 10. The deformable cover plate 22 is made of a soft elastic material with good deformability. Typically, the pressing member 2 can be made of soft TPE, TPR, TPU, EVA, LDPE, or silicone, etc., and is manufactured through an integrated injection molding process to ensure structural integrity and sealing. The deformable cover plate 22 is relatively thin and has excellent elastic recovery performance, which allows it to return to its original shape after being pressed, preventing permanent deformation.

[0037] The bottom of the storage chamber 10 is composed of a thin-walled base plate 11, which is a fragile structure with a pointed tip 211 at its lower end for piercing the thin wall. The pointed tip 211 is sharp and can effectively pierce the thin-walled base plate 11 during pressing, thereby releasing the material. To reduce the force required for piercing and improve the controllability of the rupture, several tear grooves 111 made of thinned material can be pre-cut on the thin-walled base plate 11, so that the rupture proceeds along a preset path, preventing fragments from falling off or blocking the outlet.

[0038] The upper end of the pressure column 21 is provided with a pressing plate 23 that extends outwards. The pressing plate 23 is directly connected to the top of the pressure column 21, so that when external pressure is applied to the pressing plate 23, it can be directly transmitted to the pressure column 21, pushing it downward. The outward expansion design of the pressing plate 23 significantly increases the force-bearing area, making the user feel more comfortable and the force more even when pressing. Moreover, the action can be effectively triggered no matter where the finger is pressed on the pressing plate 23, improving the convenience and fault tolerance of operation. When the pressing plate 23 is subjected to external force, the pressure column 21 moves downwards, and its tip 211 pierces the thin-walled bottom plate 11, allowing the material in the storage space to flow smoothly into the bottle through the opening, realizing automatic mixing with the beverage. This structure is based on the working principle of "sealed storage - pressing trigger - fixed-point membrane breaking - material release". Initially, the material is sealed within the storage chamber, isolating it from external moisture and contamination. During use, pressing the pressing plate 23 with a finger transmits force through the top pressure column 21 to the bottom, piercing the pre-designed weak area (thin-walled bottom plate 11). The material falls freely under gravity, achieving instant mixing. The entire process requires no opening of the bottle cap, making it simple, hygienic, and safe. It achieves dry and wet separation storage, extending the shelf life of beverages; the press-release mechanism is simple and reliable, requiring no additional tools; it offers excellent sealing, preventing moisture, leakage, and contamination; the one-piece molded structure facilitates automated production and assembly; and it provides a good user experience, with intuitive and labor-saving operation.

[0039] As a preferred solution, to prevent the pressing plate 23 from being accidentally pressed during transportation or carrying, which could lead to premature release of materials or structural damage, such as... Figures 1 to 4 As shown, the pressing plate 23 is located inside the protective cover 3. The protective cover 3 is detachably installed on the outside of the bottle cap, effectively isolating external interference and ensuring that the product remains in good condition before reaching the consumer.

[0040] As a preferred option, such as Figure 5 and Figure 7 As shown, the bottom of the pressing plate 23 is provided with a support ring 24. The top of the support ring 24 is connected to the pressing plate 23, and the bottom is connected to the deformation cover plate 22. This allows the pressure on the pressing plate 23 to be evenly transmitted to the deformation cover plate 22 through the support ring 24, causing the deformation cover plate 22 to undergo coordinated elastic deformation and avoiding local stress concentration that could lead to material fatigue or breakage. As a further optimization, the support ring 24 gradually tilts outward from the pressing plate 23 toward the deformation cover plate 22, forming a flared structure. This allows the actual supported projected area to gradually increase during pressing, effectively distributing the load and preventing the pressing plate 23 from tilting or jamming due to eccentric force, significantly improving structural stability and service life.

[0041] Preferably, the pressing plate 23 has a disc-shaped structure, which has the advantages of good symmetry and uniform force distribution. Furthermore, the upper surface of the pressing plate 23 is a spherical arc surface with a concave center. This curved surface better conforms to the natural shape of the fingertip, improving the comfort and stability of operation when pressing, while also helping to guide the finger to apply force accurately and reducing the risk of slippage.

[0042] The deformable cover plate 22 can be directly connected and installed on the bottle cap seat 1 by adhesive bonding, which is a simple and convenient connection method. In this embodiment, a more superior connection scheme is provided: the deformable cover plate 22 includes a deformable ring portion 221 located around the top pressure column 21 and bent, and a connecting ring portion 222 connected to the periphery of the deformable ring portion 221 for fixing to the bottle cap seat 1. The bottle cap seat 1 has an annular mounting surface 101 around the opening of the storage cavity 10, matching the shape of the connecting ring portion. The connecting ring portion 222 is firmly connected to the annular mounting surface 101 by a plastic hot-pressing process. Specifically, the bottom surface of the connecting ring portion 222 has a downwardly protruding connecting rib 223 for hot-melting, and the annular mounting surface 101 has a mounting ring groove 102 for accommodating the connecting rib 223. During the hot-pressing process, the connecting rib 223 melts and fills the mounting ring groove 102, forming a high-strength, high-sealing mechanical bond after cooling, ensuring that it will not fall off or leak during long-term use.

[0043] As a further optimization, the bottom of the connecting ring 222 is also provided with a sealing ring 224 located outside the connecting rib 223. The outer wall of the sealing ring 224 closely abuts against the inner wall of the storage cavity 10, forming a second sealing barrier after hot pressing. This significantly improves the sealing performance and pressure resistance of the overall structure, prevents the material from getting damp or leaking, and also enhances the structural rigidity and stability of the connection part.

[0044] Example 2

[0045] This embodiment introduces a press-type storage bottle cap, which differs from Embodiment 1 in several ways, including but not limited to: Figure 8 As shown, the bottle cap holder 1 has a concave arc surface 12 surrounding its sidewall in the middle. The curvature of this concave arc surface 12 matches the gripping posture of human fingers, forming a natural grip groove, making it easier for users to firmly grip the bottle cap holder 1 and thus more easily pull the protective cap 3 upwards. This design fully considers ergonomic principles, ensuring good operability and anti-slip performance, especially when hands are wet, sweaty, or wearing gloves. It significantly improves the user experience of removing the protective cap; enhances the overall grip and texture of the product; is suitable for high-frequency usage scenarios such as sports drinks and outdoor beverages; and has a simple structure that is easy to implement in injection molds.

[0046] Example 3

[0047] This embodiment introduces a press-type storage bottle cap, which differs from Embodiment 1 in several ways, including but not limited to: Figure 9 As shown, the upper surface of the pressing disc 23 is a spherical arc surface with a central convex shape. This design provides a slight fingertip tactile feedback while maintaining a large contact area, making the pressing action more directional. Although the convex surface has a slightly lower fit to the fingertip compared to a "central concave" design, it still offers a certain degree of comfort and practicality in certain usage scenarios (such as when operating with gloves or when seeking a light touch experience), and can improve the comfort and confidence of finger pressing to some extent. The convex structure provides both visual and tactile cues and is suitable for lightweight pressing needs.

[0048] Example 4

[0049] This embodiment introduces a press-type storage bottle cap, which differs from Embodiment 1 in several ways, including but not limited to: Figures 10 to 13As shown, the pressing disc 23 does not adopt a disc-shaped structure, but rather a polygonal structure, such as a triangle, quadrilateral, or hexagon. Of course, it can also be elliptical or other asymmetrical geometric shapes. The polygonal or elliptical pressing disc design not only enriches the product's appearance but can also be used to differentiate products with different flavors or functions (e.g., a red quadrilateral represents coffee flavor, and a blue hexagon represents lemon tea), enhancing brand recognition and user identification. Furthermore, the presence of specific corners can serve as tactile cues, helping users quickly locate the pressing area during blind operation. Diverse appearances enhance product differentiation and competitiveness; corner design guides finger positioning and avoids accidental touches; suitable for children's beverages or products designed for special groups.

[0050] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
