Portable type refrigerating packaging box

Abstract

The invention discloses a portable type refrigerating packaging box, and relates to the technical field of food cold storage. The portable type refrigerating packaging box comprises a box body of a square structure and a box cover arranged on the top of the box body, wherein a thermal-insulation layer is sandwiched in the side wall of the box body; a coolant box of a square structure is arranged in the box body; air holes are formed in the top surface of the coolant box; an elastic blocking slot adaptive to the bottom surface of the coolant box is formed in the bottom surface of an inner cavity of the box body; the coolant box is a structure with a bottom opening; and a movable bottom plate is arranged in the bottom opening of the coolant box. When the portable type refrigerating packaging box is used, the box cover is opened, so that a coolant is firstly placed into the coolant box, then, the coolant box is blocked into the elastic blocking slot in the bottom of the box body, and finally, food to be refrigerated and packaged is put into the box body; and the box cover is covered, and cold air in the coolant box flows into the box body through the air holes, so that the food is kept in a low-temperature condition, practicability is high and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of food refrigeration, and in particular relates to a portable refrigeration packaging box. Background technique [0002] All kinds of food sold on the market need to be packaged, usually in boxes. But 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., often appear on the way from the mall to home. Cold drinks or cream products melt on the way. Moreover, the melted moisture will cause the box body of the packaging box to be damp and soften. If the box body of the packaging box is softened and cannot bear the weight of the food, the box body will break and the food will fall, which will further increase the loss. [0003] The announcement number is CN106144236A, and the announcement date is November 23, 2016. The Chinese invention patent application discloses a reinforced food refrigerated packaging box...
