Description

Technical Field

[0001] This application relates to the field of lunchbox lid technology, and more specifically, to an efficient and convenient lunchbox lid. Background Technology

[0002] A lunchbox is a box specifically designed to hold food, also known as a bento box. Most lunchboxes are made of aluminum, stainless steel, or plastic. When in actual use, a lunchbox usually needs to be equipped with a matching lid.

[0003] Currently, some lunchbox lids have relatively simple structures and functions, but they generally require both hands to open simultaneously, making it impossible to open with one hand and thus reducing the overall portability of the lunchbox lid.

[0004] To address the aforementioned issues, this application provides an efficient and convenient lunchbox lid. Utility Model Content

[0005] The efficient and convenient lunchbox lid provided in this application adopts the following technical solution:

[0006] An efficient and convenient lunchbox lid includes a lunchbox lid body. A snap-fit ​​groove is provided in the middle of one side of the lunchbox lid body, and a snap-fit ​​plate is movably fitted into the middle of one side of the lunchbox lid body through the snap-fit ​​groove. A ventilated pull ring is provided through one side of the middle of the snap-fit ​​plate. A retaining ring is provided on the outer side of the bottom of the ventilated pull ring, and the retaining ring is fixedly connected to the bottom of one side of the snap-fit ​​plate. An arc-shaped groove is embedded in the bottom of the side of the snap-fit ​​plate facing away from the ventilated pull ring, and fixing blocks are fixedly connected to both ends of the bottom of the snap-fit ​​plate near the arc-shaped groove. A slot is provided on the opposite end face of the two fixing blocks. A shaft is rotatably fitted on one side of the inner wall of each of the two slots, and the two shafts are respectively fixedly connected to the inner walls of the two sides of the snap-fit ​​slot. An indicator structure is provided in the middle of the snap-fit ​​plate.

[0007] Through the above technical solution, the snap-fit ​​groove achieves a movable accommodating function for its inner structure.

[0008] Furthermore, an extension plate is fixedly connected to the tail end of the buckle plate near the arc-shaped groove. The extension plate is movably sleeved inside the buckle groove, and both ends of the bottom of the extension plate facing away from the buckle plate are fixedly connected to protruding parts. Both protruding parts are movably engaged at the two end notches at the bottom of the buckle groove.

[0009] The above technical solutions can improve the stability of the movement trajectory of the buckle plate by extending the plate and extending the protruding part.

[0010] Furthermore, a raised frame is fixedly connected to the outer periphery of the bottom of the lunch box lid body, and a sealing strip is fixedly connected to the outer surface of the raised frame.

[0011] Through the above technical solution, the sealing strip can ensure the sealing effect of the lunch box lid body on the lunch box.

[0012] Furthermore, the indicator structure includes an embedded circular groove located at the middle of the upper end of the buckle plate. The circular groove is positioned between the ventilated pull ring and the arc-shaped groove. An indicator ring is rotatably mounted inside the circular groove. The upper surface of the indicator ring is provided with an indicator scale, and an indicator block is provided on one side of the indicator scale.

[0013] Furthermore, the indicator block has an isosceles triangular shape and is fixedly connected to the top plane of one side of the buckle plate.

[0014] The above technical solution allows users to easily mark the shelf life of lunch boxes.

[0015] In summary, this application includes the following beneficial technical effects:

[0016] This application utilizes a snap-fit ​​groove on one side of the lunchbox lid body. This groove, along with the inner snap-fit ​​plate, ventilated pull ring, retaining ring, arc-shaped groove, fixing block, slot, shaft, and indicator structure, forms the snap-fit ​​structure of the lunchbox lid body. This enables the lunchbox lid body to be opened with one hand on the lunchbox, effectively improving the overall portability of the lunchbox lid. Attached Figure Description

[0027] Example:

[0028] This application discloses an efficient and convenient lunchbox lid. Please refer to [link / reference]. Figures 1 to 5The lunch box includes a lid body 1. A buckle groove 2 is provided in the middle of one side of the lid body 1. A buckle plate 3 is movably fitted into the middle of one side of the lid body 1 through the buckle groove 2. A ventilated pull ring 4 is provided through one side of the middle of the buckle plate 3. A retaining ring 5 is provided on the outer side of the bottom of the ventilated pull ring 4. The retaining ring 5 is fixedly connected to the bottom of one side of the buckle plate 3. An arc-shaped groove 6 is embedded in the bottom of the side of the buckle plate 3 facing away from the ventilated pull ring 4. Fixing blocks 7 are fixedly connected to both ends of the bottom of the buckle plate 3 near the arc-shaped groove 6. A groove 8 is provided on the opposite end face of the two fixing blocks 7. A shaft is rotatably fitted on one side of the inner wall of the two grooves 8. The two shafts are fixedly connected to the inner walls of the two sides of the buckle groove 2. An indicator structure is provided in the middle of the buckle plate 3.

[0029] An extension plate 9 is fixedly connected to the tail end of the buckle plate 3 near the arc-shaped groove 6. The extension plate 9 is movably sleeved inside the buckle groove 2. Both ends of the bottom of the extension plate 9 facing away from the buckle plate 3 are fixedly connected to protruding parts 10. Both protruding parts 10 are movably engaged at the two end notches at the bottom of the buckle groove 2. A protruding frame 14 is fixedly connected to the outer periphery of the bottom of the lunch box lid body 1, and a sealing strip is fixedly connected to the outer surface of the protruding frame 14.

[0030] The indicator structure includes an embedded circular groove 11 located in the middle of the upper part of the buckle plate 3. The circular groove 11 is located between the breathable pull ring 4 and the arc-shaped groove 6. An indicator ring 12 is rotatably installed inside the circular groove 11. The upper surface of the indicator ring 12 is provided with an indicator scale, and an indicator block 13 is provided on one side of the indicator scale. The indicator block 13 is an isosceles triangular block structure and is fixedly connected to the top plane of one side of the buckle plate 3. A screw bar is also fixedly connected to the top of the indicator ring 12 corresponding to the side of the indicator block 13. The screw bar facilitates the manual screwing operation of the indicator ring 12.

[0031] The implementation principle of this embodiment is as follows: When in use, the lunch box lid body 1 is placed on the top of the lunch box, so that the buckle plate 3 is in a flush-hidden state inside the buckle groove 2. At this time, the bottom of one side of the buckle plate 3 slides and overlaps with the top side of the lunch box through the arc groove 6, while the protruding frame 14 is in sealed contact with the upper surface of the lunch box through the sealing strip at the outer end.

[0032] When opening the lunchbox lid with one hand from the top of the lunchbox, simply insert your index finger into the inside of the vent pull ring 4. With the resistance of the retaining ring 5, you can rotate the buckle plate 3 upwards. At the same time, the two fixing blocks 7 are engaged with the two shafts through the slots 8. The bottom of one side of the buckle plate 3 slides against one side of the top of the lunchbox through the arc groove 6. The extension plate 9 and the flying part 10 on one side of the buckle plate 3 move downwards to the side of the buckle groove 2, which ensures the stability of the buckle plate 3's movement trajectory. When the buckle plate 3 is moved by the lever principle, it can simultaneously drive the lunchbox lid body 1 to tilt upwards on the lunchbox, thus realizing the one-handed opening operation of the lunchbox lid on the lunchbox.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
