ES2322002B1 - PROCEDURE OF MANUFACTURE OF ISOTHERMAL POLYURETHANE CONTAINERS. - Google Patents

Abstract

Packaging manufacturing procedure Isothermal polyurethane.

Manufacturing procedure consisting of the placement on an adherent plastic (1) of a series of packages, which will be distributed in groups of three or four according to the size, thus forming streets (2) between which the operator You can go to apply the polyurethane throughout streets formed by the containers, once applied the polyurethane one of the faces will proceed to manually turn the containers (3), so that the polyurethane is applied to a different face  to the previous one, and so on until all faces are have impregnated with polyurethane, thus obtaining a isothermal container

Description

Packaging manufacturing procedure Isothermal polyurethane.

The present invention relates to a manufacturing process of formed isothermal containers with a plastic container and polyurethane insulation foam whose purpose is the creation of a thermal container that allows the preservation of any liquid at the desired temperature regardless of external weather conditions.

The procedure would consist in the placement of plastic containers on a sheet of adherent plastic whose dimensions fit the number of containers isothermal to be manufactured at this time, these containers they will be arranged in groups of three (Fig. 1) or four rows according to the container model to be manufactured (2 liters, 5 liters, 10 liters), so that the application of the polyurethane is applied easy and homogeneous way to all sides of the container, staying in this way adhered to the container so homogeneous

Once the containers are arranged on the plastic the polyurethane will be applied through the expanded polyurethane foam projection machine getting the first face of a total of six, is isolated. Then you will proceed manually to place the containers so that another of the faces of the container and the same previous operation will be repeated leaving again discovered another of the faces of the packaging and applying on it the expanded polyurethane foam, achieving with this technique a isothermal container

This procedure has the advantage of manufacture of a large amount of isothermal containers in one time record, making the cost not high, likewise, this one procedure is environmentally friendly because the material that is not adhered to the container is in the sheet of plastic, so that at the end of the process it is removed from said plastic and sent to the appropriate recycling plants for the treatment of polyurethane waste.

Claims (3)

1. Procedure for manufacturing isothermal polyurethane containers characterized by the placement on a sticky plastic of a series of containers (1) arranged in rows forming streets (2) through which the operator can circulate with the hose applying the polyurethane, once Once the polyurethane has been applied to one of the faces, the containers will be manually turned around, so that in this way the polyurethane can be applied to another face, repeating the operation a total of six times. 2. Procedure for manufacturing isothermal polyurethane containers characterized by being formed by a polyethylene plastic container with sanitary registration on which a polyurethane layer is applied without it becoming in contact with the liquid to be consumed by the user, being therefore suitable for food use. 3. Procedure for manufacturing isothermal polyurethane containers that is characterized by being environmentally friendly by allocating the remaining polyurethane remains in the manufacturing process to appropriate recycling plants for polyurethane wastes.
