RU74898U1 - HEAT-SAVING PACKAGING BOX - Google Patents

Abstract

A heat-saving packaging box consisting of a single foldable corrugated cardboard, the walls are connected in series in the unfolded state, the upper and lower valves are a single part of the walls and are separated by a fold line, characterized in that foamed sheet polymer is sequentially glued over the entire inner surface of the box structure and aluminium foil.

Description

The proposed utility model relates to the field of containers for transportation and packaging and can be used, for example, for packaging and transportation of food products (vegetables, fruits and other food products) under the influence of low temperatures in the Far North.

Known boxes of corrugated cardboard, designed for packaging food and industrial products, are given in GOST 9142-90 "Boxes of corrugated cardboard", General specifications. However, in such boxes it is impossible to transport food products over long distances and store them for a long time without losing consumer properties under conditions of low temperatures.

The closest in technical essence (prototype) is a packaging box (application No. 2005126139, application filing date 12/20/2004) containing at least the first and second wall opposite the first wall, in which a compressible container filled with contents can be placed, as a result, the compressible container is held tightly between the first wall and the second wall due to the frictional force between the outer surface of the compressible container and the inner surfaces of the first wall and the second wall. The disadvantages include the inability to store and transport food products under conditions of low temperatures due to the single-layer execution of the walls of the packaging box from corrugated cardboard.

The objective of this utility model is to create packaging boxes that protect food products (vegetables, fruits and other food products) from freezing and loss of consumer properties in

conditions of exposure to low temperatures for a time sufficient for transportation and delivery to the consumer or storage facilities.

The technical result is achieved by creating a heat-saving packaging box. The packaging box is a one-piece sheet of folding corrugated cardboard, assembled along the fold lines and forming the box as a supporting structure. A foamed sheet polymer having heat-saving properties and an aluminum foil glued to the entire surface of the foam polymer are glued onto the entire inner surface of the corrugated cardboard to provide reflection of the product’s own thermal radiation.

The design of the heat-saving packaging box is shown in Fig. 1, where the box is made of a single foldable corrugated cardboard, while the first 1, second 2, third 3, fourth 4 walls are connected in series in the expanded state, the upper 5 and lower 6 valves are a single integral part of the walls and separated by a fold line, foamed sheet polymer 7 glued to the entire inner surface of the structure and aluminum foil 8 glued to the entire surface of the foamed polymer. On the fourth wall 4 there is a tongue 9.

In the assembled state, the upper 5 and lower 6 valves of the second 2 and fourth 4 walls are connected in the center of the box. The fourth wall 4 has a strip in the form of a tongue 9, which is connected to the first wall 1 with glue, clips or staples.

Figure 2 presents a graph of the temperature in the packaging container at an ambient temperature in the test chamber of minus 30 ° C, where curve A is the temperature in the heat-saving packaging box, curve B is the temperature in an ordinary cardboard box. As a result of the tests, it was shown that food products placed in a heat-saving box for 5-6 hours did not show signs of freezing and were completely suitable for consumption. As control samples in boxes were placed:

- grapes;

- apples;

- tomatoes;

- fresh cucumbers;

- raw chicken eggs;

- yogurt;

- sour cream.

Thus, a heat-saving packaging box made of solid folding corrugated cardboard, assembled along fold lines and forming a box as a supporting structure, foamed sheet polymer is glued to the entire inner surface, and aluminum foil is glued to the entire surface of the polymer, allows food products to be protected ( vegetables, fruits, and other food products) from freezing and loss of consumer properties under the influence of low temperatures in the Far North for the duration of atochnogo for transporting and delivering them to consumers or storage facilities.
