The invention relates to the manufacture of light portable devices that can be used for transporting and storing food and non-food products at different ambient temperatures, as well as for a seat, for example, on a picnic or fishing.

Known suitcase, multi-purpose, comprising a housing with a handle connected with the upper and lower lids, and legs with nodes attaching them to the body and legs are in the off position located under the bottom cover and serve to convert the suitcases in the stool (RF patent No. 2065712, MPC: 45 9/00, 27.08.1996 g) is similar.

The disadvantages of this solution are insufficient rigidity of products, the importance of its safe use on uneven surfaces because of its instability, and low coefficient of thermal conductivity of the material, which does not allow a long time to maintain the desired temperature range.

Known mailbox, for example, for a picnic representing a top opening of the container and the cover, and the cover is made of several parts connected by a hinge, and the side walls of the container are made of elastic material with water-repellent coating, which contains a separate insert of hard material (U.S. patent No. 4143695, MCI: 45 11/20 published 13.03.1979,) prototype.

The disadvantages of this solution are insufficient stiffness and strength, low coefficient of thermal conductivity, which does not allow to maintain the temperature of objects, for example, perishable products, virtually unchanged for a long time, and cannot be used as seats, for example, on a picnic or fishing.

Task, the solution of which is this a useful model is the creation of high-tech, lightweight, easy to carry product has high strength, rigidity, wear resistance and low coefficient of thermal conductivity in a wide temperature range.

The problem is solved in that box consisting of a body and lid, made of foam, case and/or cover is made of separate elements, and individual elements are connected to each other adhesive connection with the use of adhesives based on polyurethane with education, housing and/or cover, and the number that are glued together the elements of the body, forming its outer surface, at least one less than the number of elements forming the outer surface of the mailbox.

The box can be made of rigid polyurethane foam with density of free foaming of at least 70 kg/m3for example, m the RCTs "Izolan-430".

The mailbox can be performed with the following sizes: 8≤H/h≤120, where H is the height of the box, h is the thickness of its walls.

The box can be made with a removable lid or cover may be provided with at least one element fastening it to the body.

In the box the bonding elements of the case and/or cover can be met with the response elements, which can be, for example, the pin and the groove.

Mailbox, the individual elements of the body which can be glued adhesive selected from the conditions of adhesion to the material of the outer surface of the body elements.

The case in which at least one of the elements of the case can be configured to accommodate the at least one partition. The partition can be made removable and can be mounted to the items box.

In the bottom of the case and/or cover may be made of at least one additional cavity.

Applying the product - box, in which the housing and/or cover is made of separate elements, which is rationalized as follows:

Assembly of pre-fabricated elements of the body and/or lid of the box perform using adhesive compounds based on polyurethane, which allows not only to combine elements of the box, but to encapsulate these connect the deposits, and this in turn leads to improvement of the strength properties of the mailbox, such as resistance to weathering, low permeability, etc.;

- adhesive joints act as an additional stiffening of the drawer;

- the strength and durability of products made from separate parts, not inferior to those for solid products;

such execution mailbox provides its high technology, as molds for the manufacture of individual items are easier to manufacture, that allows you to organize their production line by way cheaper in comparison with forms for the manufacture of one-piece designs, and subject to quick change, moreover, made with violation of the requirements of the individual elements are easier and cheaper to replace than a complex selenolate product.

As you know the foams referred to as foamed plastics (plastic mass of a substance, which, in addition to the polymers include fillers, plasticizers and dyes), in which most cells are isolated from one another.

Depending on the formulation and production process of foam they come in rigid, semi-rigid and elastic. Foams, especially semi-rigid and hard, have good insulating properties (coefficient TopLop is bednesti from 0,019 to 0.035 W/(m× ° (C), and dimensional stability at temperatures of from about minus 60°to + 70°20 hours not more than 1%), water resistant (water absorption, for example, polyurethane foam does not exceed 1-8% by volume for 24 hours and depends on the specific recipe), and articles made of them have relatively high strength (tensile strength at compression of from 0.15 to 0.98 MPa).

Many properties of the foams are explained by the structural feature of their structure, namely the use in the manufacture of two phases (solid and gaseous), which gives them a high specific strength and high insulating properties. Other characteristics and mechanical strength, heat resistance, wettability, etc. is dependent on the physicochemical properties of the original components.

For the manufacture of the box you can use different foams, such as, for example, polyurethanes, polyurethane foams (PUR-3 PUR-306, "Izolan 430", "Izolan 210" etc), polystyrene foams (PS-1, PSB, PSV-H-20 and so on), phenolic foams (vilares, FER-1 and others), proprietarily (PE-2, PE-7 etc) and others.

However, one of the most widely used in industry foams are polyurethane, strength and hardness by varying a prescription factors can be changed in a wide range.

Method foaming polyurea is s made of polyurethane, which can also be rigid, semi-rigid and flexible depending on the choice of components for their manufacture.

For example, if applied to linear and often weakly branched polyesters, the polyurethanes are flexible, and if highly branched polyesters, the result of the reaction are formed with additional stitching, typical for rigid polyurethane foams.

For the manufacture of the inventive box with the achievement of the claimed technical result, as already mentioned, can be applied to various foams (e.g. polyurethane foam), which is possible by changing the ratio of the thickness of the wall of the box and its geometrical dimensions, such as height.

The experiments showed that the optimum ratio of strength, stiffness, wear resistance and processability is possible with the following ratio of the dimensions of the box: 8≤H/h≤120, where H is the height of the box, h is the wall thickness of the side of his body. If the wall thickness of the side of the box is different, the formula contains its average value.

If the ratio H/h is more than 120, or the strength characteristics of the drawer will be unsatisfactory, or to provide a high strength characteristics with a small thickness of the walls of the box should be made of expensive hard material, Thu will result in the manufacture of such boxes will cease to be efficient, if this ratio is less than 8, then a box with small size will have a wall rather large thickness, which will also lead to the deterioration of the efficiency of production.

Furthermore conducted by the applicant experiments and calculations showed that the optimal combination of strength, stiffness and processability of the box is achieved in the case of manufacturing mailbox from polyurethane foam with density of free foaming of at least 70 kg/m3or use foam having a surface hardness of not more than 60 conventional units of shore D.

As is known, the connection parts of the foams with one another or with elements of a design can be performed by mechanical means (bolts, screws, rivet connections, and so on) or by gluing.

Mechanical connection method time-consuming and not very reliable. When it is used, it is necessary to strengthen the bracket with lugs, washers or gaskets. In this regard, the most reliable method of joining parts of foam is used for bonding.

The bonding process any kind of adhesive includes a number of necessary operations: surface preparation, such as cleaning, careful adjustment of bonded surfaces, e.g. the R, using response elements, adhesive application, open exposure to the connection parts or closed shutter speed in the assembled state under some pressure, etc. and for each type of glue, this technology should be specified accordingly.

The quality of gluing a large influence may design of clamping devices (snap), which should provide a good contact of the bonding surfaces, without excessive pressure on the foam, but this pressure should ensure removal of all air bubbles from the adhesive joint and to compensate for shrinkage.

When choosing an adhesive for bonding such foams such as polyurethane foams, it is necessary to consider also that, thanks to the various combinations of polyesters and di - or polyisocyanates in their synthesis they behave differently when gluing.

For optimal results when gluing foam using polyurethane adhesives having the property of adhesion to the material of the outer surface of the housing. Depending on the material of the box it can be: ADV-11-2, ADV-15M, ADV-36, Terostat 8590, Terostat 859, ICEMA R 145/31, "Microplast" and other brands of polyurethane adhesives, but can use other types of adhesives, such as rubber, epoxy, etc.

The choice of adhesive depends on the requirements of the adhesive connection and the conditions of bonding, however, as shown by the applicant experiments, the most high strength properties and good resistance to atmospheric influences (for example, providing a low coefficient of thermal conductivity in a wide temperature range and so on) are products made of foam, the individual elements are glued with polyurethane adhesives, which are not only glued surface, but also provides sealing compounds.
