Description

Technical Field

[0001] This utility model relates to the technical field of beverage containers, and in particular to a lid. Background Technology

[0002] Currently, a freshness-locking cap has appeared on the beverage market. This cap includes an upper cap, a lower cap, and a switch mechanism for cooperating with the upper and lower caps. The cap has a cavity for storing materials such as effervescent vitamin tablets, concentrated liquids, and probiotics. The lower opening of the cavity is sealed with a sealing film. The container located below the cap contains liquid for mixing with the materials. The sealing film is cut open by the switch mechanism to allow the materials to be added into the container below. After mixing evenly, it is ready to drink.

[0003] However, most existing food-locking caps are in the form of combination caps. When the opening and closing mechanism cuts the sealing film, it needs to cooperate with the upper and lower caps. The overall structure is complex and the assembly is cumbersome. During production, it may even require multiple calibrations and adjustments, which affects production efficiency. This needs to be improved. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies, such as the need for the switch mechanism to cooperate with the upper and lower covers, the complex overall structure, and the cumbersome assembly process, by providing a new type of cover.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A lid includes an upper lid and a lower lid, the lower lid having a sealing film, and also includes a middle component and a cutting component. The upper lid is detachably mounted on the upper end of the middle component, and the lower end of the middle component is rotatably mounted on the lower lid. The upper lid, middle component, lower lid, and sealing film together form a storage cavity. The cutting component is slidably disposed within the storage cavity. The cutting component has a first groove and a second groove, and the number of the first groove and the second groove is one or more. The first groove is spiral-shaped, and the second groove extends vertically. The intermediate component and the lower cover are respectively provided with a first protrusion and a second protrusion. The number of the first protrusion and the number of the second protrusion correspond one-to-one with the number of the first slide groove and the number of the second slide groove. The first protrusion cooperates with the first slide groove. The first protrusion slides along the first slide groove as the intermediate component rotates and pushes the cutting component to move closer to or away from the sealing film. The second protrusion slides in the second slide groove. The lower end of the cutting component is provided with a cutting blade, which cuts the sealing film.

[0006] The intermediate component rotates to drive the first protrusion to slide along the spiral first groove, and works in conjunction with the second protrusion and second groove to push the cutting component to move stably in the vertical direction. This allows the cutting blade to cut the sealing film accurately and smoothly. The overall structure is more streamlined, compact, and easy to assemble. The first groove limits the rotation angle of the intermediate component, ensuring that the cutting component can move down a suitable distance and avoiding the situation where the sealing film cannot be cut completely. The number of the first groove, the second groove, and the corresponding first and second protrusions can be set to one or more, which can be flexibly adjusted according to the size of the lid, load-bearing requirements, etc., to adapt to different specifications of beverage containers.

[0007] Preferably, in the above-described cover, the lower end of the cutting element is recessed upward to form a cut-stop notch, the cut-stop notch is located between the beginning and end of the cutting blade, and the ratio of the arc length of the cut-stop notch to the circumference of the lower end of the cutting element is less than or equal to one-third.

[0008] The notch is positioned between the two ends of the cutting blade, and the ratio of the arc length of the notch to the circumference of the lower end of the cutting piece is less than or equal to one-third. This allows the cutting blade to quickly and thoroughly cut through most of the sealing film while maintaining a partial connection between the sealing film and the lower lid. This not only facilitates the smooth dispensing of materials but also prevents the sealing film from falling into the cup, thus improving the safety of the user when drinking.

[0009] Preferably, in the above-described cover, the lower cover has a rotating groove, the rotating groove includes a limiting area and a movable area, the lower cover has a notch communicating with the movable area, the intermediate piece is provided with a locking block, the notch allows the locking block to be inserted into the rotating groove, and the lower opening of the first sliding groove communicates with the upper opening of the second sliding groove. The intermediate component, the lower cover, and the cutting component are in a movable state and a limited state. In the limited state, the locking block rotates into the limited area to restrict the rotation of the intermediate component, and the first protrusion is located directly above the second protrusion on the same side. The first protrusion is inserted into the lower opening of the first slide groove, and the second protrusion is inserted into the second slide groove. In the movable state, the locking block slides in the movable area as the intermediate component rotates, and the first protrusion slides towards the upper opening of the first slide groove, with the lower surface of the first protrusion abutting against the lower inner wall of the first slide groove.

[0010] When the locking block is located within the limiting area, it can prevent the cup lid from rotating due to accidental contact. On the other hand, it can ensure that the first protrusion is precisely positioned above the second protrusion. When the part to be cut is moved downwards and assembled onto the lower cover and the middle part, the part slides along the first and second protrusions through the second slide groove. As the part moves further, the first protrusion slides from the upper opening of the second slide groove to the lower opening of the first slide groove, thus playing a guiding role when assembling the part onto the lower cover and the middle part. This eliminates the need for repeated calibration and improves the convenience of assembly. The movable area limits the rotation angle of the middle part, ensuring that the cutting action is completed smoothly. The notch provides a clear insertion channel for the locking block, allowing the middle part to be quickly assembled onto the lower cover.

[0011] Preferably, in the aforementioned cover, the intermediate component includes an inner ring and an outer ring coaxially arranged, the upper part of the outer ring is disposed on the outer wall of the inner ring, and an installation cavity is formed between the inner wall of the outer ring and the outer wall of the inner ring. The locking block is disposed on the inner side wall of the outer ring, and a first limiting ring is disposed at the upper end of the lower cover. The rotating groove is disposed on the side wall of the first limiting ring, and the first limiting ring is inserted into the installation cavity, causing the intermediate component to rotate around the first limiting ring.

[0012] The intermediate component, through the precise cooperation between the mounting cavity and the first limiting ring, enables the intermediate component to rotate stably around the first limiting ring, avoiding deviation or shaking during rotation, ensuring the stability of the first protrusion sliding along the first sliding groove, and thus ensuring the accuracy of the cutting part's movement; the locking block is set on the inner side wall of the outer ring, and the first limiting ring is inserted into the mounting cavity to realize the assembly of the intermediate component and the lower cover, making the layout of each component compact and further reducing the overall size.

[0013] Preferably, in the aforementioned cover, a second limiting ring is coaxially disposed on the lower cover and located inside the first limiting ring. The lower end of the inner ring is inserted between the first limiting ring and the second limiting ring, and the upper surface of the second limiting ring is lower than the upper surface of the first limiting ring.

[0014] The second and first limiting rings can limit the inner ring, achieving dual limiting of the intermediate component, further improving the stability of the intermediate component's rotation and the firmness of the intermediate component's assembly on the lower cover; the upper surface of the second limiting ring is lower than the upper surface of the first limiting ring, which not only provides stable support for the inner ring, but also reduces the contact area with the inner ring, ensuring smooth rotation of the intermediate component.

[0015] Preferably, in the aforementioned type of cover, the upper part of the outer ring is inclined towards the inner ring to form a supporting shoulder, and the first limiting ring is provided with an abutting slope, which abuts against the inner surface of the supporting shoulder.

[0016] By cooperating with the supporting shoulder and the abutting slope, the rotating middle part is fitted and supported, making the middle part rotate more smoothly and steadily, improving the user's feel, and preventing the cutting part from shifting due to shaking, thus ensuring the cutting effect of the sealing film.

[0017] Preferably, in the above-described cover, the outer surface of the intermediate component is provided with an anti-slip portion.

[0018] The anti-slip part increases the friction when the user's hand rotates the middle part, preventing slippage. Attached Figure Description

The upper end of the lower cover 2 is provided with a first limiting ring 9. The rotating groove 7 is disposed on the side wall of the first limiting ring 9. The first limiting ring 9 is inserted into the installation cavity 8 and causes the intermediate component 4 to rotate around the first limiting ring 9.

[0026] Preferably, a second limiting ring 91 located inside the first limiting ring 9 is also coaxially disposed on the lower cover 2. The lower end of the inner ring 43 is inserted between the first limiting ring 9 and the second limiting ring 91, and the upper surface of the second limiting ring 91 is lower than the upper surface of the first limiting ring 9.

[0027] Preferably, the upper part of the outer ring 44 is inclined towards the inner ring 43 to form a supporting shoulder 441, and the first limiting ring 9 is provided with an abutting inclined surface 901, which abuts against the inner surface of the supporting shoulder 441.

[0028] Preferably, the outer surface of the intermediate component 4 is provided with an anti-slip part 45.

[0029] Specifically, in this embodiment, the cutting element 5 is preferably a cylindrical hollow structure. There are two first grooves 51 and two second grooves 52. The second grooves 52 are symmetrically distributed on the outer side walls of both sides of the cutting element 5, and the horizontal line connecting the two second grooves 52 passes through the central axis of the cutting element 5. The lower opening of the first groove 51 is connected to the upper opening of the second groove 52.

[0033] Next, align the lower opening of the second groove 52 on the cutting piece 5 with the first protrusion 41 and insert the cutting piece 5 into the intermediate piece 4 and the lower cover 2. The cutting piece 5 slides down along the first protrusion 41 and the second protrusion 21 through the second groove 52. As the cutting piece 5 moves further down, the first protrusion 41 slides out from the upper opening of the second groove 52 and inserts into the lower opening of the first groove 51. The upper surface of the first protrusion 41 is in contact with the inner wall of the upper side of the first groove 51, and the lower surface of the first protrusion 41 is flush with the lower inner wall of the lower opening of the first groove 51. At this point, the cutting piece 5 can be assembled in place. The assembly of the cutting piece 5 can be completed simply by aligning the cutting piece 5 with the first protrusion 41, without the need for multiple reference parts, which improves the simplicity and accuracy of the overall assembly process.
