Food container and thermal forming wet press technology thereof

Abstract

The invention relates to a food container. The food container comprises an upper cover and a box body. The upper cover is located on the top of the box body and is used for tightly covering the box body. One or more first gas guide grooves which are used for exhausting gas are formed in the outer edge of the side wall, making contact with the box body, of the upper cover, and / or one or more secondgas guide grooves which are used for exhausting gas are formed in the top wall, making contact with the upper cover, of the box body. According to the food container, hot gas exhaust holes are formedby the first gas guide grooves and second openings together, and due to the mode that the hot gas exhaust holes are formed, the phenomena that condensing water vapor in a packaging box intrudes intofood, and the original taste is damaged can be avoided. Due to the structure of the first gas guide grooves of the upper cover, the structural strength and the deformation resistance of a whole packaging box body can be conveniently improved. Compared with a food container characterized in that hot gas exhaust holes are only formed in a box body, the food container with the structure has the advantages that the structural strength of the box body can be improved, deformation is avoided, and the phenomenon that dust with the small size drops to the food from the top can be avoided.

Description

technical field [0001] The present invention and the technical field of food packaging, in particular, relate to a food container for one-time holding takeaway food and a thermoforming wet pressing process for manufacturing the food container. Background technique [0002] Most of the disposable lunch boxes containing takeaway food provided in the prior art are composed of a box body and a cover body, and the box body can be arranged in a structure with different depths according to needs. This kind of lunch box is suitable for containing food with soup; For food without soup, such as baked pie or pizza, when it is contained in the above lunch box, it will emit a lot of humid heat. When the moist heat meets the lower temperature lunch box, it will be on the lid or Drops of water are formed on the side wall of the box, and if the drops accumulate more, they will drip on the surface of the food, and in severe cases, the taste of the food will be greatly reduced. In order to s...
