[0032] See also Figures 1 to 5 One embodiment of the present invention provides a portable lunch box, including: a box body 10, a box cover 20 and two handles 30.

[0033] The rear side of the box body 10 and the rear side of the box cover 20 are flipped and matched, and the left and right sides of the box body 10 are respectively connected to the two sides of the box cover 20 through the handle part 30, a first fold mark 31 is formed between the handle part 30 and the box cover 20, and a second fold mark 32 is formed between the handle part 30 and the box body 10. A unidirectional elastic fold mark 33 and an elastic limiting part 34 are formed on the handle part 30, and the unidirectional elastic fold mark 33 is located between the first fold mark 31 and the second fold mark 32, and the elastic limiting part 34 is located in the extension direction of the unidirectional elastic fold mark 33.

[0034] When the box cover 20 covers the box body 10, the handle 30 is folded through the unidirectional elastic fold 33, and the handle 30 extends out of the side of the box body 10 and the box cover 20, so that the handle 30 is convenient for the user to take the lunch box.

[0035] When the box cover 20 opens the box body 10, the handle 30 is unfolded through the one-way elastic fold 33. The box cover 20 and the two handles 30 together form a shielding cover around the box body 10. The shielding cover can prevent the droplets generated by the user when eating, and can also prevent the droplets generated by other users or flying objects in the environment from falling into the box body 10, thereby improving the safety of dining. The elastic limiting part 34 protrudes toward the inner side of the shielding cover. The elastic limiting part 34 is used to limit the folding of the handle 30 through the one-way elastic fold 33, so that the handle 30 remains in the unfolded state, and then the handle 30 can also be used to maintain the position of the box cover 20. The overall structure is simple. After opening the box cover 20, you only need to press the elastic limiting part 34 to realize that the elastic limiting part 34 protrudes toward the inner side of the shielding cover. The operation is simple and convenient to use.

[0036] It should be noted that, due to the elastic force restriction of the elastic restriction portion 34, the switching of the elastic restriction portion 34 to protrude toward the inner side and the outer side of the shielding cover needs to apply a certain elastic force to the elastic restriction portion 34. In some optional embodiments, a restriction fold mark 35 surrounding the elastic restriction portion 34 is provided on the handle portion 30. The restriction fold mark 35 facilitates the elastic restriction portion 34 to protrude toward the inner side or the outer side of the shielding cover. When the box cover 20 covers the box body 10, the restriction fold mark 35 facilitates the elastic restriction portion 34 to protrude toward the outer side of the shielding cover, so that the elastic restriction portion 34 can be folded when the handle portion 30 is folded. When the box cover 20 opens the box body 10, the restriction fold mark 35 facilitates the elastic restriction portion 34 to protrude toward the inner side of the shielding cover. At this time, due to the elastic force restriction of the elastic restriction portion 34, the elastic restriction portion 34 can restrict the folding of the handle portion 30.

[0037] In some optional embodiments, the area surrounded by the limiting fold mark 35 is smaller than the area of ​​the elastic limiting portion 34 after it is flattened. When the box cover 20 opens the box body 10, the elastic force of the elastic limiting portion 34 limits the elastic limiting portion 34 from protruding toward the outside of the shielding cover. Since the area of ​​the elastic limiting portion 34 is large, the elastic limiting portion 34 needs to be subjected to sufficient pressure to produce deformation, so that the elastic limiting portion 34 can be switched to protrude toward the outside and the inside of the shielding cover through the limiting fold mark 35.

[0038] In some optional embodiments, the elastic limiting portion 34 is further provided with a one-way elastic fold 36 connected to the one-way elastic fold 33; when the box cover 20 covers the box body 10, the elastic limiting portion 34 is first protruded toward the outside of the shielding cover, and then when the handle portion 30 is folded, the elastic limiting portion 34 is folded through the one-way fold 36, so that the handle portion 30 is folded more closely.

[0039] In some optional embodiments, the handle portion 30 includes an upper plate 37 and a lower plate 38 that are connected to each other, a first fold mark 31 is formed between the upper plate 37 and the box cover 20, a second fold mark 32 is formed between the lower plate 38 and the box body 10, and a unidirectional elastic fold mark 33 and an elastic limiting portion 34 are formed between the upper plate 37 and the lower plate 38; when the box cover 20 covers the box body 10, the upper plate 37 and the lower plate 38 are folded toward each other through the unidirectional elastic fold mark 33, and the upper plate 37 and the lower plate 38 are abutted. The user holds the upper plate 37 and the lower plate 38 at the same time, so that it is convenient to lift the box body 10 and the box cover 20 while not easily separating the box body 10 and the box cover 20.

[0040] In some optional embodiments, the handle 30, the box body 10 and the box cover 20 are integrally formed to facilitate production and assembly.

[0041] In some optional embodiments, when the box lid 20 opens the box body 10, the handle portion 30 and / or the box lid 20 gradually move away from the front side of the box body 10 in the direction upward of the box body 10, thereby preventing the shielding cover from interfering with the user's dining. In this embodiment, both the handle portion 30 and the box lid 20 gradually move away from the front side of the box body 10 in the direction upward of the box body 10.

[0042] In some optional embodiments, when the box cover 20 covers the box body 10, the handle gradually shrinks in the direction away from the box body 10, thereby reducing material and adapting to the above-mentioned situation that when the box cover 20 opens the box body 10, the handle portion 30 gradually moves away from the front side of the box body 10 in the direction above the box body 10.

[0043] In some optional embodiments, the front side of the box body 10 and the front side of the box cover 20 are detachably matched. For example, a card slot 21 is provided on the box cover 20, and a protruding card connection portion 11 is provided on the box body 10, and the card connection portion 11 is snap-fitted with the card slot 21; or, a socket is provided on the box body 10, and a bayonet is provided on the box cover 20, and the bayonet is snap-fitted with the socket.

[0044] In some optional embodiments, the handle 30 is provided with a through hole 39 for a rope to pass through. When the rope is used to tie the box body 10 and the box cover 20, the rope can pass through the through hole 39, making it convenient to lift the entire lunch box, eliminating the need to use a plastic bag for packaging. In this embodiment, both the upper plate 37 and the lower plate 38 are provided with through holes 39. When the box cover 20 covers the box body 10, the upper plate 37 abuts against the lower plate 38, and the through holes 39 of the upper plate 37 and the through holes 39 of the lower plate 38 are connected to each other.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
