Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Examples of the embodiments are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements throughout or elements having like or similar functionality. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Referring to fig. 1, a food packaging bag for microwave heating comprises an outer bag 1 and an inner bag 2 arranged in an inner cavity of the outer bag 1, wherein a second tearing line 21 which is annularly closed is formed on the surface of the inner bag 2, so that liquid in the rear inner bag 2 is heated to form steam, and the bag body is burst and exhausted from the second tearing line 21;

a U-shaped first tearing line 11 is arranged on the outer bag 1 (the front bag body), the first tearing line 11 is not closed, and a handle 12 is compounded at the opening of the first tearing line 11, so that the outer bag 1 is exhausted outwards along the first tearing line 11 at the upper opening of the outer bag 1, and the hand is prevented from contacting with high-temperature gas when tearing the bag body;

in order to avoid the hand from directly contacting the inner bag 2, the corner ends of the outer bag 1 are welded and compounded to form a holding part 3.

In view of the ease of subsequent disassembly of the bag body, a tear-off opening 13 is provided on the end side of the outer bag 1 or the inner bag 2.

The inner bag 2 is made of high temperature resistant film material, such as polyethylene film.

When the microwave bag is used, the outer bag 1 is torn from the first tearing line 11 through the handle 12, then the bag body is placed in a microwave oven for heating, and the local strength of the inner bag 2 is relatively poor due to the existence of the second tearing line 21, so that the inner bag is easy to burst from the first tearing line; after heating, the outer bag can be taken out from the holding part 3 reserved in the outer bag 1, so that the outer bag is not easy to scald.

Referring to fig. 2, in order to further insulate heat and avoid scalding, a holding plate 4 with a matched shape is compounded on the corresponding holding part 3, and the holding plate 4 is in an L shape; the holding plate 4 can be made of plastic thin plates with the same material, and the plastic thin plates are welded and compounded on the surface of the holding plate 3.

In order to avoid the soup inside the bag body from spilling, a folding groove 41 is formed in the middle of the holding plate 4 in the diagonal direction, so that the holding plate 4 can be conveniently folded inwards in a centering manner, and then the outer bag 1 can be properly folded inwards to form a bowl-shaped structure when the bag body is taken out from the diagonal end or the corner end of the bag body.

With further reference to fig. 3 and 4, the improvement is that a bending part 42 is formed at the end side of the holding plate 4 towards the inner side of the bag body, and the bending included angle alpha is 0-5 degrees, so that the corner end of the outer bag 1 is inwards folded, and the whole bowl-shaped structure is formed.

In the present utility model, the structure and connection relationship not described in detail are all the prior art, and the structure and principle thereof are already known technologies and are not described herein.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
