[0019] Referring to Fig. 1 to Fig. 5, an embodiment of the present application provides a clamp for sealing bag bodies for heating, and the clamp is capable of clamping bag mouths of sealed bags and is placed into a microwave oven for heating together with the sealed bags to prevent food from overflowing out of or polluting the microwave oven during heating. Specifically, the clamp includes an integrally formed clamp body 1, and the length L of the clamp body 1 is 10-20 cm, so that a user holds the clamp body 1 in hand for use; one or more clamping grooves 2 penetrate through and are formed in one side of the clamp body 1 in a length direction, and the bag mouths of the sealed bags only need to be inserted into the clamping grooves 2 after being folded. In the present embodiment, direction description is performed according to a state that the clamp is placed on a horizontal plane. The clamp body 1 is a microwave-heatable clamp body made of a material applicable to microwave oven heating.

[0020] Herein, the clamp and the sealed bags are independent of each other; during use, bag mouths of the sealed bags are folded firstly, the bag mouths have a certain thickness after being folded and can be fixed after being inserted into the clamping grooves 2, and thus, the sealed bags can be sealed for heating; the clamp body 1 does not need to be additionally provided with a fixing structure, and the sealed bags do not need to be provided with sealing strips, either, so that the material is saved, and energy saving and environmental friendliness are achieved. In addition, the one or more clamping grooves 2 capable of clamping a plurality of sealed bags at the same time are formed in the clamp body 1, and thus, the heating efficiency of food and the use convenience of the clamp are improved. After use, only the sealed bags need to be discarded, but the clamp can be recycled, so that the sealed bags and the clamp are more environmentally friendly in use, and the use cost is reduced.

[0021] In a specific embodiment, the clamp body 1 is a wooden clamp body or a bamboo clamp body. A wooden material and a bamboo material are both natural and environmentally friendly materials which are resistant to high temperature and high pressure, not easy to deform and good in stability and durability so as to be recycled, and are incapable of volatilizing toxic substances so as to be safer when being used for food heating and sealing.

[0022] Referring to Fig. 2 to Fig. 5, in a specific embodiment, a vertical section of each of the clamping grooves 2 in the length direction is linear, which facilitates inserting the bag mouths of the sealed bags into the clamping grooves 2, so that the use convenience of the clamp is improved. In another embodiment, a vertical section of each of the clamping grooves 2 in the length direction is curved, allowing the bag mouths to be bent after being clamped by the curved clamping grooves 2, and thus, improving sealing effects of the sealed bags.

[0023] In a specific embodiment, two opposite sides at an opening of each of the clamping grooves 2 are vertical planes 4, a filleted corner 3 is disposed on an edge of an opening in the length direction of each of the clamping grooves 2, and thus, it is convenient for the bag mouths to slide into the clamping grooves 2 while avoiding scratches on hands of a person or the sealed bags by the edge of the opening. In another embodiment, guide slopes 5 inclined from outside to inside are respectively disposed on opposite groove walls at an opening of each of the clamping grooves 2, so that the bag mouths can be further guided, it is more convenient for the bag mouths to slide into the clamping grooves 2, and the use convenience of the clamp is further improved.

[0024] In a specific embodiment, one or more clamping grooves 2 are provided. In the present embodiment, one or two clamping grooves are provided, at the moment, the use effect of the clamp is the best. When one clamp groove 2 is provided, food in the sealed bags can be sufficiently heated; and when two clamping grooves 2 are provided, two different kinds of food can be heated at the same time, avoiding the situation that the food in the two sealed bags is stacked and heated unevenly.

[0025] In a specific embodiment, when a plurality of clamping grooves 2 are provided, the plurality of clamping grooves 2 are parallel to each other. A distance D1 between the two adjacent clamping grooves 2 is greater than 2 mm, preventing the situation that the groove walls between the two adjacent clamping grooves 2 rupture due to the too small thickness while avoiding the clamp body 1 becoming too thick.

[0026] Further, the width D2 of each of the clamping grooves 2 is 2-8 mm. When the width D2 of each of the clamping grooves 2 is 2-8 mm, the folded bag mouths can be better clamped, and the bag mouths are not easy to break away from the clamping grooves 2, so that a fixing structure does not need to be additionally provided. At the same time, the depth D3 of each of the clamping grooves 2 is 1 / 2 to 4 / 5 of the width of the clamp body 1, and preferably, the depth D3 of each of the clamping grooves 2 is 2 / 3 of the width W of the clamp body 1. At the moment, the bag mouths can be sufficiently inserted into the clamping grooves 2, so that the stability of clamping the sealed bags by the clamp is improved, and groove walls away from the opening end of each of the clamping grooves 2 are less likely to rupture due to the too small thickness as well.

[0027] In a specific embodiment, an outer surface of a side, away from the clamping grooves 2, of the clamp body 1 is an arc surface 6. The arc surface 6 can be better fitted to a hand of a user, so that it is convenient for the user to hold the clamp body 1 in hand to clamp the sealed bags, and at the same time, it is not easy to scratch the hand of the user.

[0028] In a specific embodiment, anti-skid protrusions are respectively disposed on groove walls at two opposite sides at an opening of each of the clamping grooves 2. The anti-skid protrusions can be shaped like spaced protruding points or strips disposed in the length direction of each of the clamping grooves 2; and on the other hand, the anti-skid protrusions can be integrated with the clamp body 1 or made of silica gel. The bag mouths of the sealed bags are in contact with the anti-skid protrusions after being inserted into the clamping grooves 2, and the anti-skid protrusions can increase a friction force, so that the bag mouths are not easy to break away from the clamping grooves 2, and the stability of clamping the sealed bags by the clamp is further improved.
