FIG. 1 is a front side view of a first embodiment of the present invention of a composite lunch box with a volume expansion structure; fig. 2 is a rear side view of the combined lunch box with a volume expanding structure according to the first embodiment of the present invention. As shown in fig. 1 and 2, the present invention provides a combined lunch box with a volume expanding structure, which comprises a main body 10, a zipper 20 and a handle 30. The following is a detailed explanation of each component.
The body 10 includes a front side 11, a rear side 12, a containing space 13 and an opening 14; two sides and bottom edges of the front side surface 11 and two sides and bottom edges of the back side surface 12 are connected, so that an accommodating space 13 is formed between the front side surface 11 and the back side surface 12; the opening 14 is formed in the top edges of the front side surface 11 and the rear side surface 12, and the opening 14 is communicated with the accommodating space 13; the user can place a lunch or other articles in the accommodating space 13 through the opening 14.
The handle portion 30 is provided at one end of the body 10 having the opening 14. Preferably, the handle portion 30 includes two handle straps 31, two ends of the two handle straps 31 are respectively connected to the ends of the front side 11 and the rear side 12 having the opening 14; specifically, both ends of one of the straps 31 are connected to the end of the front side 11 having the opening 14, and both ends of the other strap 31 are connected to the end of the rear side 12 having the opening 14, so that the user can lift the body 10 by picking up the two straps 31.
Wherein, the lifting belt 31 of the portable part 30 of the utility model has shorter length, which can only be taken by the user or hung on the elbow; however, the length of the carrying strap 31 is not limited thereto, and can be increased as required, so that the composite lunch box with the volume expanding structure of the present invention can have the function of an oblique back or a side back.
In the first embodiment of the present invention, the front side 11 includes a block 15; the zipper 20 comprises a first zipper tooth 21, a second zipper tooth 22 and a zipper head 23; the first zipper teeth 21 extend from the front side 11 to the rear side 12, the second zipper teeth 22 are disposed around the edge of the block 15, and the zipper head 23 is movably disposed on the first zipper teeth 21 and the second zipper teeth 22.
Preferably, the block 15 is disposed between the middle of the front side 11 and the bottom edge, and the first fastener element 21 extends transversely from the middle of the front side 11 to the middle of the rear side 12. Specifically, in the first embodiment of the present invention, block 15 is adjacent to a first side 111 of front side 11, and first zipper element 21 extends from first side 111 of front side 11, through a second side 112 of front side 11 and a first side 121 of back side 12, and to a second side 122 of back side 12.
In the first embodiment of the present invention, the first side 111 of the front side 11 is a left side, the second side 112 is a right side, and the first side 121 of the rear side 12 is a left side, and the second side 122 is a right side; however, the definitions of the first side 111 and the second side 112 of the front side 11 and the first side 121 and the second side 122 of the rear side 12 are not limited thereto, and may be modified as required, such that the first side 111 of the front side 11 is a right side, the second side 112 is a left side, and the first side 121 of the rear side 12 is a right side, and the second side 122 is a left side.
