Description

Technical Field

[0001] This utility model relates to a sealing device, specifically a wine bottle sealing device. Background Technology

[0002] With the increasing popularity of alcoholic beverages and the diversification of consumption scenarios, the demand for resealing wine bottles after opening is becoming increasingly prominent. Most bottle sealers commonly found on the market employ an external clamping structure, using spring clips, buckles, or rubber stoppers to seal the bottle opening. However, these sealers often suffer from problems such as complex structure, cumbersome usage, insufficient sealing stability, or limited adaptability. For example, some sealers require pressing multiple parts simultaneously when locking, making operation inconvenient; some structures are prone to spring fatigue and decreased locking reliability after prolonged use; and some sealers are bulky, making them inconvenient to carry or store.

[0003] On the other hand, some bottle sealers, while possessing a stopper structure, have independent locking and sealing mechanisms. Users need to perform additional pressing, tightening, or combined actions on the bottle opening to achieve a seal, resulting in numerous steps and impacting the user experience. Furthermore, some bottle sealers lack a clear positioning structure during opening and closing, easily leading to incomplete locking or mis-locking, thus affecting the preservation of the wine. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a bottle sealer with a simplified structure, enabling locking and unlocking through a more intuitive operation while simultaneously ensuring a tight seal at the bottle opening. This type of structure should be small in size, compact, easy to operate, and highly reliable to meet the needs of families, personal drinking scenarios, portable outdoor scenarios, and catering establishments for rapid sealing and repeated opening of wine bottles.

[0005] This utility model is achieved through the following technical solution: a wine bottle sealing device, comprising: A bottom cover and a top cover, wherein the bottom cover and the top cover are fixedly assembled together; A rotating cover is installed outside the bottom cover, and the rotating cover is capable of reciprocating rotation relative to the bottom cover; The bottom cover has one or more locking parts on its circumferential surface. Each locking part is equipped with a locking hook. When each locking part is squeezed, the locking hook is pushed out and locks the bottle mouth of the outer container.

[0006] As a preferred technical solution, the locking part has elastic deformation capability, and a compression positioning mechanism is provided between the bottom cover and the rotating cover.

[0007] As a preferred technical solution, the extrusion positioning mechanism includes an arc-shaped positioning groove disposed on the inner side of the rotating cover and an arc-shaped extrusion protrusion disposed on the outer side of the locking part. When the arc-shaped extrusion protrusion is engaged into the arc-shaped positioning groove, each locking hook is pushed out.

[0008] As a preferred technical solution, the inner side of the rotating cover is provided with one or more movable limiting cavities, and the outer side of the bottom cover is provided with a protruding rotating limiting part. The rotating limiting part is snapped into the movable limiting cavity, thereby limiting the rotation angle of the rotating cover each time.

[0009] As a preferred technical solution, a sealing plug is also included, which is installed at the middle position of the bottom of the bottom cover for sealing the outer container; As a preferred technical solution, the top cover and the bottom cover are connected by a snap-fit ​​detachable connection.

[0010] The beneficial effects of this utility model are as follows: By setting a compression positioning mechanism between the bottom cover and the rotating cover, the user only needs to rotate the rotating cover to apply pressure to the locking part on the bottom cover, thereby pushing out the locking hook to achieve quick locking of the bottle mouth. The overall operation does not require complicated pressing actions, and the usage method is intuitive and convenient. The locking part has elastic deformation capability, which allows the locking hook to reliably reset between the released state and the locked state, making the structure more stable and durable. The inner side of the rotating cover is provided with a movable limiting cavity that cooperates with the rotating limiting part on the outer side of the bottom cover, so that each rotation has a clear angular stopping position, avoiding uneven locking or accidental unlocking due to excessive rotation, and improving the accuracy and reliability of operation. Meanwhile, a sealing plug is installed in the middle of the bottom cap, so that the sealer can seal the inside of the bottle mouth while locking it, which can further slow down the evaporation of the wine and improve the preservation effect; the top cap and bottom cap adopt a snap-on disassembly structure, which is convenient for cleaning and maintenance and reduces the cost of use.

Detailed Implementation

[0012] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0013] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0014] like Figures 1-4 As shown, in one specific embodiment of this utility model, the bottle sealer has an overall cylindrical structure, consisting of a bottom cap 4, a top cap 1, and a rotating cap 2 as the main outer shell components. The bottom cap 4 and the top cap 1 are fixedly assembled, forming a shell structure with a circumferentially closed and an open top, which is used to house the locking mechanism and sealing components.

[0015] The front cover 1 and the bottom cover 4 can be connected by a snap-fit ​​assembly structure during manufacturing. The snap-fit ​​assembly is achieved by the circumferentially distributed snaps and limiting flanges. This method is beneficial for users to clean and maintain the internal structure after long-term use, and it is also convenient for production and subsequent assembly.

[0016] A rotatable cover 2 is fitted onto the outside of the base cover 4. The rotatable cover 2 is fitted onto the outside of the base cover 4 via a ring-shaped fitting, allowing it to rotate within a reciprocating angle range around the circumference of the base cover 4. In the specific structure, the inner wall of the rotatable cover 2 is slightly larger than the outer diameter of the base cover 4, forming a fitting gap between them. The rotation angle is limited at appropriate positions by a limiting structure, thereby ensuring smooth rotation while preventing excessive rotation that could cause structural damage or failure of the locking function.

[0017] At least one locking part 8 is provided on the circumferential surface of the bottom cap 4, and usually there are multiple evenly distributed locking parts 8 to achieve a more stable gripping effect on the bottle mouth. Each locking part 8 is composed of a structural segment that can undergo elastic deformation. The structural segment has an arc-shaped extrusion protrusion 9 on its outer surface for being squeezed, and extends to its inner side or end to form a locking hook 5 for engaging with the bottle mouth.

[0018] When the locking part 8 is in its natural state, the locking hook 5 is in the retracted position and will not interfere with the bottle mouth; when the locking part 8 is squeezed by external force, its elastic section deforms inward, and the locking hook 5 pushes outward, which can abut against the lower edge of the bottle mouth to form a locking effect.

[0019] The compression positioning mechanism provided between the bottom cover 4 and the rotating cover 2 is used to realize the automatic compression function of the locking part 8. In the specific structure, the inner surface of the rotating cover 2 is provided with an arc-shaped positioning groove 10 along the circumferential direction. The arc-shaped positioning groove 10 has a stepped or concave shape and is used to apply compression force to the arc-shaped compression protrusion 9 during rotation.

[0020] When the user rotates the rotating cap 2, the arc-shaped positioning groove 10 on the inner wall of the rotating cap 2 will sequentially contact and gradually engage with the arc-shaped pressing protrusions 9 on each locking part 8, causing the arc-shaped pressing protrusions 9 to be subjected to inward pressing force, which in turn pushes the locking part 8 to undergo elastic deformation, pushing out the locking hook 5 and locking the bottle mouth. When the rotating cap 2 rotates in the opposite direction, causing the arc-shaped pressing protrusions 9 to disengage from the positioning groove, the locking part 8 returns to its original shape under its own elastic action, and the locking hook 5 retracts accordingly, thereby realizing the unlocking operation of the bottle mouth.

[0021] To further ensure the stability and controllability of the rotating cover 2 during operation, one or more movable limiting cavities 7 are provided on the inner side of the rotating cover 2, and a corresponding rotating limiting part 6 is provided on the outer side of the bottom cover 4. The rotating limiting part 6 is formed with a protruding structure. When the rotating cover 2 is sleeved on the outside of the bottom cover 4, the rotating limiting part 6 is engaged in the movable limiting cavity 7, so that the rotation path of the rotating cover 2 is restricted by the edge of the movable limiting cavity 7. This clearly defines the starting and ending positions of the locking and unlocking actions, giving each rotation a clear sense of positioning. This prevents user misoperation from causing the locking part 8 to be not fully squeezed or the locking hook 5 to be mispositioned, thereby improving the overall reliability of use.

[0022] In this embodiment, a sealing plug 3 is also provided at the center of the bottom of the bottom cap 4. The sealing plug 3 is fixed to the middle of the bottom cap 4 by insertion or press-fitting, and its size matches the inner diameter of the bottle neck of most wine bottles. When the sealer is installed on top of the wine bottle, the sealing plug 3 can be inserted into the bottle neck to form a filling-type sealing structure inside the bottle neck, effectively preventing the evaporation or leakage of the wine inside the bottle. The sealing plug 3 is usually made of food-grade silicone or rubber material with a certain degree of elasticity, so that it can form a tight contact with the inner wall of the bottle neck, while having good durability and sealing performance.

[0023] In actual use, the user aligns the sealing plug 3 of the sealer with the bottle neck and gently presses it axially to insert the sealing plug 3 into the bottle neck. Then, rotating the rotating cap 2 causes the arc-shaped positioning groove 10 to gradually apply pressure to the arc-shaped extrusion protrusion 9, causing the locking hooks 5 of the locking part 8 to push out and lock onto the outer edge of the bottle neck, thus securing the sealer stably at the bottle neck. When the bottle needs to be opened, the user rotates the rotating cap 2 in the opposite direction to release the locking part 8 from the pressure, causing the locking hooks 5 to retract, and the sealer can be easily removed. The entire operation requires only simple pressing and rotating actions to complete the locking and unlocking process. Its compact structure, ease of use, and strong adaptability meet the needs of repeated bottle sealing.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
