Abstract
Description
Technical Field
[0001] This utility model relates to a lunch box, and more particularly to a novel lunch box with a built-in storage space in the lid. Background Technology
[0002] Plastic lunch boxes, as convenient containers for carrying food, are commonly used for meals while working in the field. After meals, food residue often gets stuck between teeth, requiring the use of dental floss picks or toothpicks. It's essential to carry dental floss picks or toothpicks when dining in the field; forgetting to bring them will cause the inconvenience of not being able to clean your teeth.
[0003] Chinese utility model patent CN210726956U discloses a lunchbox, which includes a first box body and a second box body disposed at its lower end. The second box body has three sliding grooves inside, each containing a first drawer block, a second drawer block, and a third drawer block. The third drawer block has a third drawer cavity for placing napkins or toothpicks, and the third drawer cavity contains a binding component for securing the napkins or toothpicks. While this lunchbox can store toothpicks, allowing customers to bring them while dining out, the design of the third drawer cavity takes up space that would otherwise be used for food storage, resulting in some wasted space. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of lunch box with built-in storage space in the lid.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel lunch box with a built-in storage space in the lid, comprising a box body and a detachable lid, the lid comprising a bottom cover and a frame cover, the bottom cover having a protrusion, the frame cover having a protruding receiving opening that mates with the protrusion of the bottom cover, a receiving groove being provided around the protrusion, and the frame cover having a closing plate at the protruding receiving opening, when the frame cover and the bottom cover are engaged, the closing plate and the receiving groove together form a storage space for placing dental floss or toothpicks.
[0006] Specifically, the cross-sectional width of the storage space is D, and 0.8cm < D.
[0007] Specifically, the cross-sectional height of the storage space is H, where 1cm < H.
[0008] Specifically, the lower edge of the bottom cover is provided with an embedded groove for installing a sealing ring.
[0009] Specifically, the inner groove and the receiving groove of the bottom cover are offset from each other.
[0010] Specifically, the receiving groove of the bottom cover is disposed around the protrusion.
[0011] Specifically, the outer edge of the frame cover is provided with a snap-fit plate for engaging with the box body.
[0012] Specifically, the inner wall of the frame cover is provided with a protruding buckle for fastening the bottom cover.
[0013] The beneficial effects of this utility model are as follows: This utility model adopts a structural design that combines a bottom cover and a frame cover. The receiving groove of the bottom cover and the closing plate of the frame cover together form a storage space at the lid, which is convenient for carrying dental floss sticks. Compared with the prior art, this utility model stores dental floss sticks in the storage space of the lid, without occupying the food storage space of the box, and effectively utilizes the storage space of the lid.

Detailed Implementation
[0019] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0020] As attached Figure 1 As shown, a novel lunchbox with a built-in storage space in the lid includes a box body 10, a detachable lid 20, and a snap-fit plate 223 on the outer edge of the lid frame 22 for engaging with the box body 10. (See attached diagram.) Figure 3As shown, the box cover 20 includes a bottom cover 21 and a frame cover 22. The bottom cover 21 has a protrusion 211, and the frame cover 22 has a protrusion receiving opening 221 that cooperates with the protrusion 211 of the bottom cover 21. A receiving groove 212 is provided around the protrusion 211, and the receiving groove 212 of the bottom cover 21 is specifically arranged around the protrusion 211. The frame cover 22 has a closing plate 222 at the protrusion receiving opening 221.
[0021] When the frame cover 22 and the bottom cover 21 are engaged, the closing plate 222 and the receiving groove 212 together form a storage space for holding dental floss picks 30 or toothpicks. This storage space can also hold one or two packaged disposable film gloves. (See attached diagram) Figure 3 As shown, when it is necessary to remove the dental floss stick 30 from the lid 20, you can directly press the protrusion 211 of the bottom cover 21 with your thumb to separate the frame cover 22 from the bottom cover 21, and then remove the dental floss stick 30 from the receiving groove 212 of the bottom cover 21.
[0022] Combined with appendix Figure 3 and attached Figure 4 As shown, the cross-sectional width of the storage space is D. Since the conventional width of the dental floss stick 30 is about 0.8 cm, 0.8 cm < D. The cross-sectional height of the storage space is H. Since the conventional thickness of the dental floss stick 30 is about 1 cm, 1 cm < H. By limiting the range of the cross-sectional width D and cross-sectional height H of the storage space, it can be ensured that the dental floss stick 30 can be placed into the receiving groove 212 of the bottom cover 21, and it can be avoided that the bottom cover 21 and the frame cover 22 cannot be fastened due to the dental floss stick 30 pushing up the frame cover 22.
[0023] Combined with appendix Figure 4 As shown, the lower edge of the bottom cover 21 has an embedded groove 213 for installing a sealing ring (note: not shown in the attached drawings). The lid 20 covers the box body 10 and is fixedly connected to the box body 10 by a snap-fit plate 223, and the sealing ring provides a seal. In addition, since the lid 20 adopts a structural design that combines the bottom cover and the frame cover, food and soup in the box body 10 cannot leak out from the lid 20.
[0024] The inner groove 213 of the bottom cover 21 and the receiving groove 212 are staggered, so that the cover 20 as a whole does not need to be very thick to store dental floss picks 30. (See attached...) Figure 2 and attached Figure 4 As shown, the inner wall of the frame cover 22 is provided with a protruding buckle 224 for fastening the bottom cover 21. The frame cover 22 can be separated from the bottom cover 21 by pressing the protrusion 211 of the bottom cover 21 directly with the thumb.
[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
