Description

An insulated packing box

technical field

The utility model relates to a packing box, in particular to a thermal insulation packing box.

Background technique

When the packaging box is used for the transportation of ingredients and fruits, in order to ensure the freshness of the ingredients and fruits, it is necessary to put fresh-keeping media in the packaging box, such as ice cubes, dry ice, etc. Since dry ice is solid carbon dioxide, the temperature is about minus 78°C. At room temperature, dry ice is extremely volatile; moreover, when dry ice volatilizes, the surrounding temperature will drop sharply, and there is a potential risk of frostbite to the human body.

Therefore, ordinary cargo transportation cannot use dry ice as a fresh-keeping medium, and ice cubes are generally used as a fresh-keeping medium. At present, the practice in the industry is generally to directly put ice cubes into the packaging box, then put the packaged or directly transported food and fruit into the packaging box, and finally seal the packaging box. When the ice cube melts, it will take away a lot of heat to ensure that the transported ingredients and fruits are kept in a low temperature environment. However, the melting of ice cubes will also produce a large amount of water. After the transported food and fruit come into contact with water, it will accelerate the deterioration of the food and fruit, making the taste of the food and fruit worse, thereby affecting its freshness preservation effect. Moreover, the ice cubes will occupy the space of the packing box after being placed in the packing box, which reduces the capacity of the packing box.

Utility model content

In view of the above shortcomings, the purpose of this utility model is to provide a thermal insulation packaging box, which has the functions of refrigeration, freshness preservation and heat preservation, and has good effects of cold preservation, freshness preservation and heat preservation.

As a further improvement of the present utility model, a transverse hollow plate is arranged on the bottom wall of the box and located below the cold air filling cavity, and the transverse hollow plate communicates with the longitudinal accommodating cavities, and each of the longitudinal accommodating cavities A spacer net is arranged at the joint with the transverse hollow plate.

As a further improvement of the utility model, a bottom honeycomb paper core is arranged on the bottom wall of the box and below the transverse hollow plate.

As a further improvement of the utility model, a honeycomb cold insulation layer is arranged on the lower end surface of the box cover and directly above the packaging cavity.

As a further improvement of the utility model, a number of hole plugs that are snapped into the upper end of the longitudinal accommodating cavity are arranged downward on the lower edge of the box cover.

As a further improvement of the utility model, the longitudinal accommodating cavity is in the shape of a cylinder.

As a further improvement of the utility model, the thickness of the side wall of the box is 5-8 cm.

As a further improvement of the utility model, the diameter of the longitudinal accommodating cavity is 2-4cm.

As a further improvement of the utility model, the width of the cold air filling cavity is 1-2 cm.

The beneficial effects of the utility model are:

(1) The refrigerating substance "nanofluid coolant" is placed in the longitudinal accommodating cavity on the side wall of the box instead of in the packaging cavity, which not only improves the refrigeration and fresh-keeping effect, but also ensures the The items are separated from the refrigerated substance, so that the items are not easy to deteriorate, and the internal capacity of the packaging cavity is not occupied;

(2) By adding a cold air filling cavity and using it in conjunction with the refrigerating substance "nano-fluid coolant", a cold source is provided for the items in the box. Obtain a uniform cold source, ensure that the items in the packaging cavity are evenly cooled, and improve the effect of freshness preservation and heat preservation;

(3) A honeycomb paper core is added on the outer arm of the box. Since the honeycomb paper core has the characteristics of light weight and good heat preservation performance, it can further insulate the items in the box;

(4) By adding a honeycomb cold insulation layer on the lower end surface of the box cover, the effects of cold insulation, heat preservation and freshness preservation are further improved.

The above is an overview of the technical solution of the utility model, and the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
