Food cold storage packaging box

Abstract

The invention discloses a food cold storage packaging box. A box body of the packaging box comprises a box cover, a box main body and a box bottom, and square strengthened tubes are arranged at the positions, located on the four corners of a containing cavity, of the box main body; inner grooves of the square strengthened tubes are coolant storage chambers, and through holes are fully distributed in two tube walls of the containing cavity; a protruding plate is arranged on the box cover, and the interior of the protruding plate sinks inwards to form a concave structure, and protruding structures are arranged on the four corners; the protruding structures are right located over the coolant storage chambers; and a groove is formed in the upper end of the box bottom, and a water draining channel with a U-shaped structure is arranged below the groove. The square strengthened tubes are arranged on the food cold storage packaging box, on the one hand, the whole structural strength of the packaging box is improved, and on the other hand, the inner grooves of the square strengthened tubes are utilized as the coolant storage chambers, and cold storage and freshness retaining of foods can be effectively achieved; and the box body is reasonable in structure arrangement, gel generated inside the box body can be guided to be drained out of the box body in time, water accumulation can be effectively prevented, and quality of the transported foods can be ensured.

Description

technical field [0001] The invention relates to the field of product packaging, in particular to a food refrigeration packaging box. Background technique [0002] All kinds of food sold on the market need to be packaged, usually in boxes. However, there are many foods that need to be refrigerated and kept fresh, such as various fresh foods, cold drinks, and cream products that are afraid of heat, etc., and it often happens that the cold drinks or cream products have melted on the way from the mall to home. In order to solve this type of problem, people set a cool storage agent in the packaging box to cool down the inside of the box body, so as to realize refrigeration and preservation. [0003] In the existing food refrigerated packaging boxes, on the one hand, due to the use of the cooling agent, water will be accumulated in the box during transportation, which seriously affects the quality of some foods; The structural strength of the body has higher requirements. Cont...
