Abstract
Description
Technical Field
[0001] This application relates to the field of bottle cap technology, and more specifically, to a sealing cap for beverage bottles. Background Technology
[0002] In the beverage packaging industry, the design of the sealing cap plays a crucial role in product safety, sealing performance, and user experience. Currently, most beverage bottle sealing caps on the market use a threaded connection structure. A sealing connection is achieved by screwing the threads on the inside of the cap onto the external threads of the bottle opening. Simultaneously, to prevent unauthorized opening during transportation and storage and to ensure product quality and safety, many sealing caps are also equipped with an anti-theft ring structure. This anti-theft ring is typically connected to the bottom of the cap via several connecting bridges. When the cap is opened, the connecting bridges break, serving as the basis for determining whether the packaging has been opened.
[0003] However, the existing threaded connection and anti-theft ring for beverage bottle caps have obvious defects in actual use. Because the cap needs to ensure good sealing to prevent beverage leakage and spoilage, the threaded connection is usually designed to be tight. In addition, the anti-theft ring connecting bridge has a certain strength, which makes it difficult for consumers to open the cap. For the elderly, children and people with less strength, opening such caps is difficult and affects the user experience. Summary of the Invention
[0004] The purpose of this application is to provide a beverage bottle sealing cap that can solve the technical problems mentioned in the background art.
[0005] This application provides a beverage bottle sealing cap, including a sealing cap body, an anti-theft ring, and connecting bridges. The bottom of the sealing cap body is connected to the anti-theft ring through multiple connecting bridges. The top of the sealing cap body is provided with a folding member, which is hinged to the top edge of the sealing cap body. The top of the sealing cap body is provided with a fixing structure that cooperates with the folding member. When the folding member is unfolded, it forms a lever structure with the sealing cap body to assist in opening the sealing cap body.
[0006] Furthermore, the top of the sealing cover body is provided with a groove for receiving the folded component. The depth of the groove is adapted to the thickness of the folded component. When the folded component is folded and stored, the surface of the folded component is flush with the top of the sealing cover body.
[0007] Furthermore, the folding component includes a connecting part and a force-bearing part. The sealing cover body has an opening on one side of the groove, and a rotating shaft is fixed at the opening. The connecting part has a through hole that matches the rotating shaft. The connecting part is rotatably connected to the rotating shaft through the through hole. The force-bearing part has a connecting groove. The end of the connecting part away from the rotating shaft is located in the connecting groove and is rotatably connected to the connecting groove.
[0008] Furthermore, the end of the connecting part away from the rotating shaft is provided with an anti-detachment protrusion ring, and the force-bearing part is provided with an anti-detachment ring groove adapted to the anti-detachment protrusion ring in the connecting groove, and the anti-detachment protrusion ring is rotatably connected to the anti-detachment ring groove.
[0009] Furthermore, the force-bearing part is annular, and a hand-grip groove is provided on the inner ring side of the force-bearing part away from the connecting part.
[0010] Furthermore, a pair of arc-shaped plates are symmetrically fixed to the top of the sealing cover body. The outer curvature of the arc-shaped plates is adapted to the inner ring side of the force-bearing part. A magnet is embedded on the outer side of the arc-shaped plates, and the magnet can be magnetically connected to the force-bearing part.
[0011] Furthermore, the sealing cover body is fixedly provided with a column, and the connecting part is provided with an insertion groove adapted to the column. When the folding part is unfolded, the column can be inserted into the insertion groove.
[0012] Furthermore, the inner side of the sealing cover body is provided with internal threads, and the inner side of the anti-theft ring is provided with a one-way oblique tooth buckle.
[0013] Furthermore, the sealing cover body has a silicone sealing block at its top, and the bottom of the silicone sealing block has an annular groove. The silicone sealing block is made of food-grade silicone.
[0014] The beneficial effects of this utility model are:
[0015] This invention uses a folding component to form a lever structure, which amplifies the small force applied by the user into a greater opening force.

[0029] like Figure 1-3As shown, this application provides a beverage bottle sealing cap, including a sealing cap body 1, an anti-theft ring 2, and connecting bridges 3. The bottom of the sealing cap body 1 is connected to the anti-theft ring 2 via multiple connecting bridges 3. The top of the sealing cap body 1 is provided with a folding member 4, which is hinged to the top edge of the sealing cap body 1. The top of the sealing cap body 1 is provided with a fixing structure that cooperates with the folding member 4. When the folding member 4 is unfolded, it forms a lever structure with the sealing cap body 1 to assist in opening the sealing cap body 1. In use, the sealing cap body 1 is threadedly sealed to the bottle mouth, and the anti-theft ring 2 surrounds the outside of the bottle mouth. The connecting bridges 3 are not broken, indicating that the sealing cap body 1 has not been opened. When it is necessary to open the sealing cap body 1, the user manually removes the folding member 4 from the fixing structure. Release allows the folding component 4 to unfold outward around the hinge point. At this time, the folding component 4 becomes the "power arm" of the lever. The user applies force to the outer end of the folding component 4, and using the lever principle, a torsional torque is generated on the sealing cap body 1. The torsional torque helps the sealing cap body 1 overcome the friction between the threads, causing the sealing cap body 1 to rotate and loosen. The connecting bridge 3 between the sealing cap body 1 and the anti-theft ring 2 breaks due to the rotation of the bottle cap, and the anti-theft ring 2 remains at the bottle mouth, indicating that the bottle cap has been opened, thus realizing the anti-theft function. The lever structure formed by the folding component 4 amplifies the small force applied by the user into a larger opening force, which is especially suitable for children, the elderly, or people with weak hand strength. It solves the pain point of traditional bottle caps being "difficult to unscrew" and improves the user experience.
[0030] like Figure 1-3 As shown, the top of the sealing cover body 1 is provided with a groove 11 for storing the folding piece 4. The depth of the groove 11 is adapted to the thickness of the folding piece 4. When the folding piece 4 is folded and stored, the surface of the folding piece 4 is flush with the top of the sealing cover body 1. When the folding piece 4 is folded, it fits the top of the sealing cover body 1 without adding any extra protrusion, thus keeping the appearance of the sealing cover body 1 neat.
[0031] like Figure 1-3As shown, the folding component 4 includes a connecting part 41 and a force-bearing part 42. The sealing cover body 1 has an opening on one side of the groove 11, and a rotating shaft 5 is fixed at the opening. The connecting part 41 has a through hole 411 that matches the rotating shaft 5. The connecting part 41 is rotatably connected to the rotating shaft 5 through the through hole 411. The force-bearing part 42 has a connecting groove 421. The end of the connecting part 41 away from the rotating shaft 5 is located in the connecting groove 421 and is rotatably connected to the connecting groove 421. When unfolded, the user manually lifts the force-bearing part 42 from the groove 11. The force-bearing part 42 rotates upward around the rotating shaft 5. At this time, the connecting part 41 rotates upward with the force. Part 42 rotates synchronously, while connecting part 41 rotates relative to it within connecting groove 421. When force-receiving part 42 unfolds to form 180° with sealing cover body 1, force-receiving part 42 is rotated so that force-receiving part 42 forms a certain angle with the vertical direction of sealing cover body 1. In the lever structure formed by folding part 4 and sealing cover body 1, the fulcrum is the pivot 5, the power arm is the distance from pivot 5 to the force-applying point of force-receiving part 42, and the resistance arm is the distance from the center of sealing cover body 1 to pivot 5. By applying force to force-receiving part 42, the torque is amplified using the lever principle, which helps to unscrew sealing cover body 1.
[0032] like Figure 1-3 As shown, the end of the connecting part 41 away from the rotating shaft 5 is provided with an anti-detachment protrusion ring 412, and the force-bearing part 42 is located in the connecting groove 421 and is provided with an anti-detachment ring groove 422 that is adapted to the anti-detachment protrusion ring 412. The anti-detachment protrusion ring 412 and the anti-detachment ring groove 422 are rotatably connected. The engaging structure of the anti-detachment protrusion ring 412 and the anti-detachment ring groove 422 prevents the connecting part 41 from separating from the force-bearing part 42 from a physical perspective, avoiding damage or detachment of the folding part 4 due to external force pulling. The rotatable connection between the connecting part 41 and the force-bearing part 42 allows the user to adjust the angle of the force-bearing part 42 according to their gripping habits, making the power arm direction more flexible and improving opening comfort.
[0033] like Figure 1-3 As shown, the force-bearing part 42 is annular, and a handle groove 423 is provided on the inner ring side of the force-bearing part 42 away from the connecting part 41. The handle groove 423 is provided to facilitate the user to separate the folding part 4 from the fixing structure on the top of the sealing cover body 1, so as to facilitate the unfolding of the folding part 4.
[0034] like Figure 1-3 As shown, a pair of arc-shaped plates 6 are symmetrically fixed on the top of the sealing cover body 1. The outer arc of the arc-shaped plate 6 is adapted to the inner ring side of the force-receiving part 42. A magnet 7 is embedded on the outer side of the arc-shaped plate 6. The magnet 7 can be magnetically connected to the force-receiving part 42. The folding part 4 and the pivot 5 are metal products, while the sealing cover body 1, the anti-theft ring 2 and the connecting bridge 3 are plastic products. The pivot 5 is embedded and fixed in the opening on one side of the groove 11 on the top of the sealing cover body 1. When opening, the user only needs to apply an external force slightly greater than the magnetic force (such as hooking the finger on the grip groove 423 and pulling upward) to break the magnetic connection and cause the folding part 4 to unfold.
[0035] like Figure 1-3 As shown, the sealing cover body 1 is fixedly provided with a column 8, and the connecting part 41 is provided with an insertion groove 413 adapted to the column 8. When the folding part 4 is unfolded, the column 8 can be inserted into the insertion groove 413. When an external force (such as a finger hooking the gripper groove 423) is applied to the force-bearing part 42, the connecting part 41 is driven to rotate around the rotating shaft 5, and the folding part 4 gradually unfolds. At this time, the column 8 is aligned with the opening direction of the insertion groove 413. As the connecting part 41 rotates to a preset angle (such as 180°), the column 8 is inserted into the insertion groove 413, forming a mechanical limit, so that the folding part 4 maintains a stable unfolded posture.
[0036] like Figure 2 As shown, the inner side of the sealing cap body 1 is provided with an internal thread 12, and the inner side of the anti-theft ring 2 is provided with a one-way oblique tooth buckle 21. The internal thread 12 on the inner side of the sealing cap body 1 is engaged with the external thread on the outer side of the bottle mouth. The sealing cap and the bottle mouth are fixedly connected by rotating and tightening. The tip of the one-way oblique tooth buckle 21 faces the tightening direction of the sealing cap body 1. This is a conventional structural design in the field of bottle cap technology and will not be described in detail here.
[0037] like Figure 2 As shown, a silicone sealing block 9 is provided on the inner top of the sealing cap body 1, and an annular groove 91 is provided on the bottom of the silicone sealing block 9. The silicone sealing block 9 is made of food-grade silicone. When the silicone sealing block 9 is tightened in conjunction with the sealing cap body 1, the sealing performance is increased. Specifically, when the sealing cap body 1 is tightened, the annular groove 91 cooperates with the bottle mouth to improve the sealing path.
[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
