Abstract
Description
Technical Field
[0001] The utility model relates to a lunch box, in particular to a novel lunch box capable of draining water. Background Art
[0002] A lunch box is a household appliance used to carry and store food, making it convenient to take food to eat elsewhere. In modern work and life, many professionals bring their own lunch to work, making lunch boxes a daily necessity. Eating a moderate amount of fruit after a meal helps promote digestion and achieve balanced nutrition. Many people have a habit of eating fruit after lunch, commonly known as "fruit after lunch." Fruit needs to be washed before consumption. For fruits with larger grains, such as grapes and cherry tomatoes, draining is necessary after washing to prevent moisture from accumulating underneath and spoiling the taste. After lunch, using a lunch box as a container to wash fruit is simple and convenient, eliminating the need to carry separate fruit-washing utensils. Currently, most existing lunch boxes have a drain function. Adding a drain function to a lunch box without compromising the seal that holds food has become a challenge that needs to be overcome. To this end, we have proposed a new type of lunch box with a drain function. Utility Model Content
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel lunch box capable of draining water.
[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a new type of drainable lunch box, comprising a box body and a box cover cooperating with the box body, the box cover comprising an outer frame and a bottom cover, the bottom cover being detachably buckled to the lower part of the outer frame, the outer frame being provided with a downwardly concave frame surface, there being a height difference between the edge of the outer frame and the frame surface, an inclined portion being between the edge of the outer frame and the frame surface, the outer frame being provided with a drain groove, the drain groove extending from the frame surface to the edge of the outer frame and passing through the inclined portion.
[0005] To further illustrate, an inner groove for installing a sealing ring is formed on the edge of the bottom cover.
[0006] It is further explained that the outer side of the outer frame is movably connected to a buckle piece for snap connection with the edge of the box body.
[0007] It is further explained that the inner wall of the outer frame is provided with a convex buckle portion for buckling with the bottom cover.
[0008] To further illustrate, the frame surface is provided with a middle opening, and when the bottom cover member is buckled onto the outer frame member, the cover surface of the bottom cover member is exposed from the middle opening of the outer frame member.
[0009] To further elaborate, the drain grooves are symmetrically provided on the left and right sides of the outer frame.
[0010] The beneficial effects of the utility model are that the utility model is simple to operate and easy to use, can be used for portable meals, and can also be used for washing and draining fruits, so that the lunch box has an increased drainage function without destroying the sealing function of the lunch box for storing food.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0019] Combined with attachment Figure 1 and attached Figure 2 As shown, a new type of lunch box with drainability includes a box body 10 and a box cover 20 that matches the box body 10. Figure 3 As shown, the box cover 20 includes an outer frame 21 and a bottom cover 22. The bottom cover 22 is detachably mounted on the lower portion of the outer frame 21. The outer side of the outer frame 21 is movably connected to a buckle 215 for buckling with the edge of the box body 10. Figure 2 and attached Figure 3 As shown, the edge of the bottom cover 22 is provided with an inner groove 221 for mounting a sealing ring. When lunch is needed, the lunch is simply placed into the box body 10 and the lid 20 is closed. The sealing ring of the lid 20 is pressed into contact with the box body 10, and the lunch is sealed in the lunch box.
[0020] As attached Figure 3 As shown, the inner wall of the outer frame 21 is provided with a convex buckle portion 216 for buckling with the bottom cover 22. When assembling the box cover 20, the outer frame 21 is provided with a convex buckle portion 216 for buckling with the bottom cover 22. Figure 3 As shown, the outer frame 21 is simply snapped onto the bottom cover 22, with the convex buckle portion 216 of the outer frame 21 snapping onto the edge of the bottom cover 22. The frame surface 211 has a central opening 214, and when the bottom cover 22 is snapped onto the outer frame 21, the cover surface of the bottom cover 22 is exposed from the central opening 214 of the outer frame 21.
[0021] Combined with attachment Figure 6 As shown, the outer frame 21 has a downwardly concave frame surface 211. There is a height difference between the edge of the outer frame 21 and the frame surface 211. There is an inclined portion 212 between the edge of the outer frame 21 and the frame surface 211. The outer frame 21 has a drain groove 213 extending from the frame surface 211 to the edge of the outer frame 21 and passing through the inclined portion 212. The drain grooves 213 are symmetrically provided on both the left and right sides of the outer frame 21.
[0022] Combined with attachment Figure 4 As shown, after washing the fruits such as grapes and small tomatoes in the box body 10, the box cover 20 is placed upside down on the upper side of the box body 10. Then, as shown in the attached Figure 5 As shown, hold the lunch box at an angle so that the water in the box body 10 can drain out from the drain groove 213. The utility model is simple to operate and easy to use. It can be used for both portable meals and fruit washing and draining, thereby increasing the drainage function of the lunch box without destroying the sealing function of the lunch box for storing food.
