Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically to a quick-opening push-button switch cap for bottled containers. Background Technology

[0002] Currently, the most common bottle cap opening methods on the market include rotary, flip-top, and push-button types. Rotary bottle caps require multiple rotations to open or close, which is inconvenient and time-consuming; flip-top bottle caps open quickly, but the connecting parts are easily damaged, and the sealing performance is often poor; existing push-button bottle caps mostly use a top-press unlocking structure, but they have problems such as complex structure, high pressing force, and easy accidental opening.

[0003] Existing push-button bottle caps unlock by pressing the center of the cap, typically requiring significant pressure and making one-handed operation difficult. Furthermore, this structure is prone to elastic fatigue after frequent use, leading to incomplete sealing. While some side-press designs improve ease of use, their unlocking mechanisms are more complex, resulting in higher production costs and inconvenient assembly. Therefore, the current technology lacks a bottle cap structure that is simple in structure, requires minimal effort to operate, provides a reliable seal, and allows for quick and easy opening and closing.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a quick-opening push-button switch cover.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a quick-opening push-button switch cover, comprising: The cap base includes a base plate, a connecting sleeve located at the upper end of the base plate, and connecting posts disposed on both sides of the connecting sleeve; the base plate has an installation opening in the middle that can be fitted into the corresponding bottle neck, the inner diameter of the connecting sleeve is the same as the diameter of the installation opening and their center lines coincide; the connecting sleeve and the connecting posts are both fixed on the base plate. A locking sleeve is disposed above the base of the cover body. The locking sleeve includes a pressing sleeve, and pressing areas are provided on both sides of the pressing sleeve. An elliptical locking ring is provided in the middle of the pressing sleeve. The two connecting ends of the locking ring along the long axis are fixedly connected to the inner wall of the pressing sleeve. The connecting ends of the locking ring are respectively the first connecting end and the second connecting end, and are provided corresponding to the pressing areas on both sides. The top cover is located above the pressing sleeve and is vertically connected to the cover base.

[0007] This design features a locking ring with a specific elliptical structure, which effectively locks the bottle opening in its natural state to prevent accidental opening. When opening is required, it can be quickly unlocked by pressing the pressing areas on both sides. The overall structure is compact and reasonable, and the operation is simple and quick, greatly improving the convenience of use.

[0008] Furthermore, when the locking ring is not under stress, its two connecting ends maintain an elliptical shape; when under pressure, the major axis of the locking ring gradually decreases and the minor axis gradually increases. Pressure on the connecting ends refers to the consumer pinching the pressing area of ​​the pressing sleeve with their fingers and applying force, causing the inner connecting ends to experience pressure towards the center of the locking ring, causing the locking ring to gradually change from an elliptical shape to a circular shape. In this design, the locking ring undergoes controllable elastic deformation under pressure, achieving a smooth transition from the locked to the unlocked state, ensuring rapid release of the bottle opening, while maintaining reliable locking in its natural state, thus improving the product's reliability.

[0009] Furthermore, the locking ring's minor axis gradually decreases from bottom to top, and its inner wall is arc-shaped, curving inwards from bottom to top. The minor axis length at the lower end of the locking ring is greater than or equal to the inner diameter of the connecting sleeve, while the minor axis length at the upper end of the locking ring is less than the inner diameter of the connecting sleeve. The diameter of the bottle mouth matches the diameter of the mounting port and the connecting sleeve. The bottle mouth enters the connecting sleeve from bottom to top through the mounting port and then passes through the locking ring. Due to the smaller minor axis length at the upper end of the locking ring, the upper end of the locking ring can hold the bottle mouth. When the cap needs to be removed, simply pinch the pressing area of ​​the pressing sleeve and apply slight force to deform the locking ring through the connecting end, i.e., the major axis decreases and the minor axis increases. When the minor axis length at the upper end of the locking ring is greater than the diameter of the bottle mouth, the locking ring unlocks the bottle mouth, and the bottle separates from the cap. This design employs a gradient short shaft, which makes the bottle insertion process smoother and ensures that the upper end of the locking ring can effectively lock the bottle opening, preventing the cap from accidentally falling off and improving the product's sealing performance and safety.

[0010] Furthermore, the top cover includes a top plate, an inner top sleeve disposed at the lower end of the top plate, and an outer retaining sleeve disposed outside the inner top sleeve; the inner top sleeve is located above the locking ring, and limit baffles are provided on both sides of the inner top sleeve corresponding to the short axis direction of the locking ring. This solution, by providing limit baffles on the inner top sleeve, can effectively limit the deformation range of the locking ring under stress, prevent structural damage caused by excessive deformation, and improve the structural stability and service life of the product.

[0011] Furthermore, the connecting post is secured between the inner top sleeve and the outer sleeve; each of the two connecting posts has a locking strip on its outer side, and the outer sleeve has a locking position corresponding to the locking strip, with the locking strip engaging with the locking position. This design employs a locking strip and locking position cooperation structure, making the connection between the cover base and the top cover more secure and reliable, simplifying and facilitating the assembly process, while also enhancing the overall structural strength and improving the product's durability.

[0012] Furthermore, a groove is provided on the inner side of the pressing sleeve, and a retaining edge is provided on the outer side of the outer retaining sleeve, with the retaining edge engaging with the groove. This design achieves a reliable connection between the locking sleeve and the top cover through the tight fit between the retaining edge and the groove, preventing relative rotation or loosening during use and improving the stability and safety of the product.

[0013] Furthermore, the inner side of the connecting column is provided with several reinforcing ribs, and the connecting column and the connecting sleeve are connected by the reinforcing ribs. In this design, the reinforcing ribs significantly improve the connection strength between the connecting column and the connecting sleeve, effectively preventing deformation or damage caused by stress during use, and ensuring the long-term reliability of the product.

[0014] Furthermore, both the first and second connecting ends are inverted T-shaped structures. The T-shaped connecting end structure increases the contact area with the inner wall of the pressing sleeve, improves the connection strength, makes the pressure transmission more uniform and stable, and ensures the controllability and stability of the locking ring transformation process.

[0015] Furthermore, the wall thickness of the locking ring is 0.8~1.2mm. In the structural design of both the pressing sleeve and the locking ring, the wall thickness meets the corresponding elastic deformation conditions, allowing for a certain degree of elastic deformation under manual pressing. The optimized wall thickness range ensures that the locking ring has sufficient elastic deformation capacity for easy unlocking, while also ensuring its structural strength, preventing plastic deformation due to frequent use, and improving the product's service life.

[0016] Furthermore, the base, locking sleeve, and top cover are all made of polypropylene and are each integrally molded. Using polypropylene and integral molding ensures excellent elasticity and durability of each component, while also guaranteeing dimensional accuracy and consistency, significantly reducing production costs and improving product quality stability.

[0017] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: 1. This utility model features a double-sided pressing design, allowing users to unlock the lock ring simply by lightly pinching the pressing area. The operation is simple and quick, making it particularly suitable for one-handed operation.

[0018] 2. This utility model adopts a split structure design, with the cover base, locking sleeve and top cover connected by a snap-fit ​​method, which makes assembly simple and reduces production costs.

[0019] 3. The locking ring of this utility model can tighten the bottle mouth by contracting the short shaft in its natural state, effectively preventing liquid leakage; after being deformed by pressure, it can quickly release the bottle mouth, achieving both sealing performance and convenient opening and closing.

[0020] 4. All components of this utility model are integrally injection molded from PP material to ensure sufficient elastic deformation capacity and structural strength.

[0021] 5. The locking ring of this utility model requires pressing on both sides simultaneously to unlock, which can prevent accidental opening. Attached Figure Description

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] Example: See appendix Figure 1 As shown, the quick-opening push-button switch cover of this utility model mainly includes three parts: cover base 1, locking sleeve 2, and top cover 3.

[0029] See appendix Figure 2As shown, the cap base 1 includes a base plate 11, a connecting sleeve 12, and connecting posts 13. The base plate 11 is a circular plate structure with an installation opening 111 in its center for fitting the bottle neck. The connecting sleeve 12 is vertically mounted on the upper end of the base plate 11, and its inner diameter is the same as the diameter of the installation opening 111 and their center lines coincide to ensure smooth passage of the bottle neck. The connecting posts 13 are symmetrically arranged on both sides of the connecting sleeve 12 and are integrally formed with the base plate 11. The inner side of the connecting posts 13 is provided with several reinforcing ribs 131, which are connected to the outer wall of the connecting sleeve 12 to improve structural strength.

[0030] See appendix Figure 3 As shown, the locking sleeve 2 is located above the cap base 1 and includes a pressing sleeve 21 and a locking ring 22. The pressing sleeve 21 has a cylindrical structure with recessed or non-recessed pressing areas 211 on its two outer walls to facilitate user application of force. The locking ring 22 is located in the center of the pressing sleeve 21 and has an elliptical structure. Its two ends along its major axis form a first connecting end 221 and a second connecting end 222, which are fixedly connected to the inner wall of the pressing sleeve 21. The ring wall of the locking ring 22 bends inward from bottom to top, causing its minor axis to gradually decrease. In its natural state, the length of the minor axis at the upper end of the locking ring 22 is less than the diameter of the bottle mouth, and the length of the minor axis at the lower end is greater than or equal to the inner diameter of the connecting sleeve 12.

[0031] See appendix Figure 4 and attached Figure 5 As shown, the top cover 3 is located above the locking sleeve 2 and includes a top plate 31, an inner top sleeve 32, and an outer retaining sleeve 33. The inner top sleeve 32 extends downward from the center of the lower end of the top plate 31, located above the locking ring 22, and has limiting baffles 321 on both sides in the short axis direction to prevent excessive deformation of the locking ring 22. The outer retaining sleeve 33 extends downward from the lower end of the top plate 31 and the outer side of the inner top sleeve 32, and is inserted into the inside of the pressing sleeve 21. The outer retaining sleeve 33 has a retaining edge 331 on its outer side, which engages and fixes with the retaining groove 212 on the inner side of the pressing sleeve 21.

[0032] See appendix Figure 6 As shown, the base 1 and the top cover 3 are connected by a connecting post 13. The connecting post 13 is engaged between the inner top sleeve 32 and the outer sleeve 33, and its outer side strip 133 engages with the slot 332 on the outer sleeve 33 to achieve vertical fixation.

[0033] Working principle: When the bottle neck is inserted into the mounting port 111 and passes through the connecting sleeve 12, the upper end of the locking ring 22, due to its smaller short axis, locks the outer side of the bottle neck, thus achieving a lock. When the cap needs to be opened, the user simultaneously pinches the pressing areas 211 on both sides with their thumb and forefinger. The pressure is transmitted to the locking ring 22 through the first connecting end 221 and the second connecting end 222, causing its long axis to decrease and its short axis to increase. When the length of the short axis at the upper end of the locking ring 22 is greater than the diameter of the bottle neck, the bottle neck is released, and the cap can be removed.

[0034] This invention employs a double-sided press-to-unlock structure, enabling rapid opening and reliable sealing of the bottle cap. The elliptical locking ring design effectively locks the bottle opening in its natural state by contracting its short axis, preventing liquid leakage. When the pressing areas on both sides are pressed, the locking ring undergoes controllable deformation, with the long axis decreasing and the short axis increasing, thus achieving rapid unlocking. This structure not only saves effort and supports one-handed operation but also prevents excessive deformation through a limiting baffle, extending its service life. The split design combined with the snap-fit ​​connection simplifies the assembly process and reduces production costs. Furthermore, the one-piece molding of polypropylene material ensures the elasticity and durability of the components. The overall structure combines the advantages of rapid opening and closing, reliable sealing, and prevention of accidental opening, making it particularly suitable for bottled containers that require frequent opening.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
