Description

Technical Field

[0001] This utility model relates to the field of container lid technology, specifically to a container lid structure that prevents it from falling off. Background Technology

[0002] With social development and the improvement of people's living standards, the demand for various containers is increasing, and correspondingly, the performance requirements for container lids are also becoming higher. Flip-top container lids, with their convenient opening and closing advantages, occupy an important position in the market. Currently, common flip-top container lids typically consist of a lid and a base connected by a hinge structure, often using a pin and hole. However, this traditional connection structure has a significant drawback: during frequent opening and closing, wear easily occurs between the pin and the hole, increasing the clearance and reducing the lid's stability during rotation. In some cases, the lid may even detach axially along the pin. This is especially problematic when the container is used to hold liquids or other leak-prone items, as a detached lid can cause leakage, resulting in loss and inconvenience. In addition, the closing and locking structure of some existing container lids is poorly designed, resulting in an insufficiently tight connection between the lid and the base sleeve after closing. This makes them prone to opening during handling or vibration, affecting the container's sealing and safety. Furthermore, the complex connection methods of some container lid components lead to low production and assembly efficiency, increasing manufacturing costs. In summary, existing flip-top container lids suffer from problems such as easy lid detachment, poor closure stability, and unreasonable structural design, failing to meet users' demands for high-performance container lids. Therefore, it is necessary to improve and optimize their structure. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a container lid structure that prevents the lid from falling off during opening and closing, ensures the stability of the connection between the lid and the bottom sleeve, and ensures smooth opening and closing of the lid, thereby improving the performance and service life of the container lid.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A container lid structure designed to prevent detachment includes a lid, a base sleeve, and a ring. The ring is connected to the side of the base sleeve, and one side of the base sleeve is fitted onto one end of the ring. The lid is movably connected to the ring, and the lid can rotate around the ring to achieve opening and closing. The rotation angle range is 0-180 degrees, and the lid will not detach during rotation due to the limiting effect of the ring. The cover has a through hole on one side, which is located near the edge of the cover. There is a rotation gap between the inner wall of the through hole and the outer wall of the ring. The ring passes through the through hole to meet the rotation requirements while preventing the cover from detaching along the ring axis. The inner side of the cover is equipped with a set of limiting bosses. The set of limiting bosses is located on the inner side of the cover near the sleeve through hole. It includes a first limiting boss and a second limiting boss, which are respectively installed on the same side inside the cover and are arranged symmetrically. The space between the two bosses is formed for the circular part structure to move. The inner side of the bottom sleeve is provided with a slot, which is located on the inner side of the bottom sleeve near the side. A rectangular through-hole block is installed on one side of the slot, and a channel for a ring to pass through is left between the rectangular through-hole block and the slot. One end of the ring is provided with a groove, which is adapted to be installed in the slot inside the base sleeve. The groove and the slot are positioned to further limit the displacement of the ring relative to the base sleeve in the horizontal and vertical directions. The inner side of the cover is provided with a concave snap-fit ​​position, which is located on the inner side of the cover away from the sleeve through hole. The bottom sleeve is provided with a convex snap-fit ​​part that is adapted to the concave snap-fit ​​position. The convex snap-fit ​​part and the concave snap-fit ​​position can be precisely aligned when the cover is closed. When the cover is closed, the convex snap-fit ​​part is embedded in the concave snap-fit ​​position to form a snap-fit, which improves the connection stability between the cover and the bottom sleeve after closing.

[0005] The beneficial effects of this utility model are: 1. Excellent anti-fall-off effect: The cover and the bottom sleeve are connected by a ring. The through hole on the cover is fitted onto the ring. The limiting boss on the inner side of the cover limits the end of the ring. The ring also effectively limits the axial movement of the cover. At the same time, the groove at one end of the ring is matched with the slot on the inner side of the bottom sleeve, further limiting the displacement of the ring relative to the bottom sleeve. This effectively prevents the cover from falling off along the axial direction of the ring during opening, closing and rotation, ensuring the stability of the connection between the cover and the bottom sleeve. 2. Smooth opening and closing: There is a rotation gap between the inner wall of the sleeve hole of the cover and the outer wall of the ring, which provides enough space for the cover to rotate around the ring, making the opening and closing of the cover smoother and reducing the occurrence of jamming. 3. High closure stability: The concave snap-fit ​​position on the inside of the lid matches the convex snap-fit ​​piece on the bottom sleeve. When the lid is closed, the convex snap-fit ​​piece is embedded in the concave snap-fit ​​position to form a lock, effectively preventing the lid from opening on its own when closed, thus improving the closure stability and sealing performance of the container lid. 4. Simple and reasonable structure: This utility model has a small number of parts, and the connection between the parts is simple, making it easy to manufacture and assemble, which can improve production efficiency and reduce manufacturing costs. 5. Long service life: Due to the reasonable design of the fit between the various components, wear and tear are reduced, thus extending the service life of the container lid.

[0008] To facilitate understanding of this utility model, a more complete description of it will be provided below with reference to the accompanying drawings. The drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0009] like Figure 1-4 As shown, this utility model discloses an anti-detachment container lid structure, including a lid 1, a base sleeve 2, and a ring 3. The ring 3 is longitudinally connected to the sides of the lid 1 and the base sleeve 2, and is located at a slightly lower position on the side of the lid 1 and a slightly higher position on the side of the base sleeve 2. The lid 1 and the base sleeve 2 are movably connected by the ring 3. Both the lid 1 and the base sleeve 2 are fitted onto the ring 3. The lid 1 can rotate around the ring 3 to achieve opening and closing actions. The rotation angle can be flexibly adjusted between 0 and 180 degrees, and it will not fall off during rotation due to the limiting protrusion group 5 on the inner side of the lid 1 and the limiting effect of the ring 3. The cover 1 has a through hole 4 on one side. The through hole 4 is located near the edge of the cover 1. There is a rotation gap between the inner wall of the through hole 4 and the outer wall of the ring 3. The ring 3 passes through the through hole 4. This design satisfies the need for the cover 1 to rotate around the ring 3, and also restricts the cover 1 from detaching along the axial direction of the ring 3. A limiting boss assembly 5 is installed on the inner side of the cover 1. The limiting boss assembly 5 is located on the inner side of the cover 1 near the sleeve through hole 4 and is connected to the edge of the sleeve through hole 4. The limiting boss assembly 5 includes a first limiting boss 51 and a second limiting boss 52, which are respectively installed on the same side inside the cover 1 in a symmetrical layout. The space formed between the two bosses is adapted to the size of the ring 3, which can play a certain limiting and restraining role on the ring 3 when the cover 1 rotates. The setting of the limiting boss assembly 5 can play a certain guiding and limiting role during the rotation of the cover 1, further ensuring the stability of the rotation of the cover 1 and preventing the cover 1 from swaying left and right during rotation. The inner side of the base sleeve 2 is provided with a slot 6, which is located near the side of the inner side of the base sleeve 2 and maintains a certain distance from the side of the base sleeve 2. A rectangular through-hole block 7 is installed on one side of the slot 6. The channel width of the rectangular through-hole block 7 is slightly larger than the diameter of the ring 3, so that the ring 3 can pass through and engage with the slot 6. One end of the ring 3 is provided with a groove 8, which is adapted to the slot 6 installed on the inner side of the base sleeve 2. The end of the ring 3 with the groove 8 passes through the rectangular through-hole block 7 of the base sleeve 2 and engages with the slot 6. Through this connection method, the displacement of the ring 3 relative to the base sleeve 2 in the horizontal and vertical directions is further restricted, ensuring the firmness of the connection between the ring 3 and the base sleeve 2. Even when subjected to external impact, the ring 3 will not easily detach from the base sleeve 2. The inner side of the cover 1 is provided with a concave snap-fit ​​position 9, which is located on the inner side of the cover 1 away from the sleeve through hole 4 and maintains a certain distance from the edge of the cover 1. The bottom sleeve 2 is provided with a convex snap-fit ​​member 10 that is adapted to the concave snap-fit ​​position 9 at the corresponding position. The convex snap-fit ​​member 10 also maintains a corresponding distance from the edge of the bottom sleeve 2. When the cover 1 is closed, the convex snap-fit ​​member 10 can be accurately embedded in the concave snap-fit ​​position 9 to form a snap-fit, thereby improving the connection stability between the cover 1 and the bottom sleeve 2 after closing. At the same time, this position setting makes the snap-fit ​​force more uniform and extends the service life of the snap-fit ​​structure. In this embodiment, during assembly, the end of the ring 3 with the groove 8 is first passed through the rectangular through hole block 7 of the base sleeve 2, so that the groove 8 of the ring 3 is matched and engaged with the slot 6 on the inner side of the base sleeve 2, thus completing the connection between the ring 3 and the base sleeve 2; then, the sleeve through hole 4 of the lid 1 is fitted onto the ring 3, so that the lid 1 is connected to the ring 3. At this time, the lid 1 can rotate freely around the ring 3, realizing the opening and closing action of the container lid. During the rotation of the cover 1, the limiting boss group 5 limits the ring 3, and the fitting relationship between the sleeve through hole 4 and the ring 3 effectively prevents the cover 1 from falling off along the axial direction of the ring 3. When the cover 1 is closed, the convex snap-fit ​​member 10 on the bottom sleeve 2 is embedded in the concave snap-fit ​​position 9 on the inner side of the cover 1, forming a stable engagement, ensuring that the cover 1 will not open by itself when closed. Working principle The core of this invention's anti-fall-off flip-top container lid structure lies in the movable connection between the lid 1 and the bottom sleeve 2 via the ring 3, and the structural cooperation between the various components to achieve the functions of preventing fall-off and stable closure. When the container lid needs to be opened, an external force is applied to make the lid 1 rotate around the ring 3. Due to the rotational gap between the inner wall of the sleeve hole 4 of the lid 1 and the outer wall of the ring 3, and the guiding effect of the fit between the limiting boss assembly 5 and the ring 3, the lid 1 can rotate smoothly. During the rotation, the ring 3 provides axial restraint for the lid 1, and at the same time, the limiting boss assembly 5 on the inner side of the lid 1 can limit the rotation range of the lid 1, preventing the lid 1 from being damaged due to excessive rotation, ensuring that the lid 1 rotates stably and will not fall off along the axial direction of the ring 3. When the container lid needs to be closed, the lid 1 is rotated in the opposite direction. As the lid 1 rotates, the convex locking piece 10 on the base sleeve 2 gradually approaches the concave locking position 9 on the inner side of the lid 1. Because the positions of the convex locking piece 10 and the concave locking position 9 are precisely aligned, when the lid 1 is fully closed, the convex locking piece 10 can smoothly embed into the concave locking position 9 to form a lock, thereby stably connecting the lid 1 and the base sleeve 2, preventing the lid 1 from opening on its own when closed, and ensuring the sealing of the container lid. At the same time, this locking structure can also reduce the collision between the lid 1 and the base sleeve 2, reducing noise. In addition, the groove 8 at one end of the ring 3 is adapted to engage with the slot 6 on the inner side of the base sleeve 2, and the ring 3 passes through the rectangular through-hole block 7 of the base sleeve 2. The rectangular through-hole block 7 provides auxiliary support for the ring 3. This connection method effectively limits the displacement of the ring 3 relative to the base sleeve 2, ensuring the firmness of the connection between the ring 3 and the base sleeve 2, thereby ensuring the stability and reliability of the entire container cover structure.
