## Title
Thermal panel

## Abstract

The present invention refers to a thermal panel of thermal foam, characterized in that said thermal panel includes three isolating layers, in which the first layer, is an aluminized layer or film which serves as a film reflecting to temperature; the second layer, is a corrugated plastic sheet that serves as a temperature diffuser; and the third layer is an isolating foam plate, which serves to isolate any change of temperature in the environment.

## Background
This invention refers to a thermal panel, particularly, a panel made of with three isolating layers that oscillate from −20° C. to 120° C. for the preservation of food.
BACKGROUND OF THE INVENTION
In the present, there exist several portable items for the preservation of foods, mainly known as “coolers”: however, said items are still cumbersome and expensive.
There also exist the refrigerators used by restaurants for the preservation of food, but in the case of home delivery, they need to send food in trays or boxes transported by a vehicle at ambient temperature, which causes food to change its temperature, deriving in the consumer's displeasure.
The reinforcement of the present invention, is to provide preferably a thermal panel; particularly, a portable thermal panel made of thermal foam with three isolating layers oscillating from −20° C. to 120° C. for the preservation of food basically with a light weight.
Said thermal panel is used as a wall to be placed inside the containers, made either from fabric or vinyl, and might be adjusted to any size with the intention of thermally isolating, and transporting, and thereby preserve the temperature of its contents, either cold or hot in accordance with the temperature ranges that oscillate between −20° C. to 120° C.
Said panels may be placed inside a container, either rigid or flexible, in their use position in order to preserve the desired temperature of a product, and when the containers need to be cleaned or kept in their storage position, said panels need only to be removed from said container, thereby saving space, particularly for flexible containers such as bags or backpacks.
Likewise, the thermal panel provides resistance either to tension and/or compression; therefore, its physical properties are not altered, even under severe or rough use conditions.



BRIEF DESCRIPTION OF DRAWINGS
The aforementioned characteristics of the invention shall become evident after referring the following detailed description and the accompanying drawings, from which:
FIG. 1, is a view en perspective of the thermal panel in accordance with the present invention.
FIG. 2, is a side view of the thermal panel in accordance with FIG. 1.
FIG. 3, is an exploded view of the thermal panel in accordance with the present view.
FIG. 4, illustrates the thermal panel in its use condition in accordance with the present invention.



DETAILED DESCRIPTION OF INVENTION
The preferred modalities of the invention shall be described in detail below, with reference to the accompanying drawings.
FIGS. 1 and 2 show the portable thermal panel made of thermal foam (10) with three isolating layers at temperatures that oscillate from −20° C. to 120° C. for the preservation of foods, basically of light weight.
Said thermal panel (10) shall be used in a varied shape and thickness. FIG. 3 illustrates the thermal panel (10) on a exploded view with the intention of indicating the layers that compose the same. Said layers are related in the following manner:
The layer (11), is an aluminized layer or film that serves as a film reflecting to temperature. The layer (12), is a corrugated plastic sheet that works as a temperature diffuser. Finally, the layer (13) is an isolating foam plate, which isolates any change of temperature in the environment. On the other hand, the relation of the thickness that includes the isolating foam plate (13) with regard to the aluminized film (11) and the corrugated plastic sheet (12) is completely variable.
Application
FIG. 4 illustrates, as an example, a series of thermal panels (10) arranged in the internal periphery of a container (14) or bag (not illustrated) for the preservation of temperature. When the temperature of a particular product needs to be preserved, the thermal panels (10) are placed in such a manner that the aluminized film (11) is oriented outwards, that is to say, towards the internal walls of the container (14) or bag. If the container (14) needs to be kept at a high temperature (heat) inside, said panels are placed (10) in the inverse sense, that is to say, the face of the isolating foam plates (13) shall be oriented towards the internal walls of the container (14) or bag.
Novelty of Invention
Upon description of the invention, the contents of the following claims has been claimed as property:

## Claims

1. A portable, removable, reversible thermal panel made of thermal foam, used as a wall to be placed inside a bag or container, characterized in that, said thermal panel has three temperature isolating layers, in which
the first layer is an aluminized layer or film that serves as a temperature reflecting film;
the second layer is a corrugated plastic sheet that serves as a temperature diffuser; and
the third layer is a temperature isolating foam plate which serves to isolate any change of temperature between an object that has been placed adjacent to the wall inside of the bag or container and an environment which substantially surrounds an outside of the bag or container such that the wall can be reversed depending upon whether the object that has been placed adjacent to the wall is relatively hot or cold.

2. The thermal panel in accordance with claim 1, wherein the three temperature isolating layers isolate temperatures that range from −20° C. to 120° C.
