Description

DESCRIPTION

Thermal bag

TECHNIQUE SECTOR

The present invention refers to a thermal bag, which presents a multilayer structure from which better conservation performance of the products housed within it is derived.

The bag is complemented by containers that fit perfectly and are stackable within it, thus optimizing its carrying capacity.

The object of the invention is to provide a thermal bag that functions as a refrigerator, which allows the food and/or drinks contained within it to be kept at an optimal temperature for consumption as long as possible.

BACKGROUND OF THE INVENTION

Although the use of portable thermal containers is notable, it should be said that normally this type of container is made from a body with two layers, between which an insulation chamber is established, and the same occurs with the corresponding lid, which only it has the hermetic closing function of said thermal bag.

In short, this type of thermal bag has a limited thermal insulation capacity, which it would be desirable to increase.

This problem is increased when the device is materialized in a thermal bag.

In addition to these limitations, a second problem should be highlighted, and it is the distribution of the food products within the thermal bag, so that when using containers of different sizes to store the products to be consumed, these do not usually adapt to the exact dimensions of the interior of the thermal bag, which is why a large part of the bag's capacity always ends up being wasted.

EXPLANATION OF THE INVENTION

The thermal bag that is recommended satisfactorily solves the aforementioned problem, offering continuous insulation throughout its interior with the absence of thermal bridges and with a structure that optimizes its storage capacity.

To this end, the bag of the invention is made up of a main body open at the top, with strongly rounded edges, and a coupling lid on the previous one, complementing the bag set with a handle for manual transport / on the shoulder of the thermal bag associated with said main body.

More specifically, both the main body and the lid have a sandwich-type structure, formed from three layers, an outer shell-like layer made of polypropylene, an intermediate layer made of EPS, and an inner layer made of polypropylene. polypropylene base, with the three layers of the main body affected on their smaller side faces with holes that coincide with each other, for the passage of a rivet for fixing the carrying handle.

This handle will preferably be made of leather, and may incorporate means for adjusting its length.

In accordance with another of the characteristics of the invention, provision has been made for the main body to define an internal chamber with a constant horizontal section throughout its entire height, so that this chamber is complemented by a series of containers that can be stacked together, of dimensions in plan according to said section, and of a submultiple height of the same so that the containers are stacked tightly within the bag, once filled with the food or products in question, allowing to optimize the storage space, by taking advantage of this one 100% against what happens with conventional thermal bags.

These containers will include a practicable upper lid, with a perimeter relief that fits in a complementary recess established on the underside of the base of said container, thus achieving extremely stable stacking.

In this way, a thermal bag with high insulation performance is achieved, allowing the products contained within it to be kept for up to 12 hours between 5 and 15°C.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 3.- Shows an exploded view of the bag's multilayer structure.

Figure 4.- Shows a perspective view of one of the containers that can be stacked tightly within the bag.

Figure 5.- Shows a view similar to that of figure 3, but with the container with its lid open.

Figure 6.- Finally, it shows a longitudinal section view of a pair of containers like those of figures 4 and 5 properly stacked together.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, and especially figure 3, it can be seen how the thermal bag of the invention is made up of a main body open at the top and a coupling lid on the previous one, complementing the whole of the thermal bag. with a handle (8) for manual/shoulder transport of the thermal bag.

The main body is formed from three layers, an outer layer (4) in the form of a shell made of polypropylene, an intermediate layer (5) made of EPS, and an inner layer (6) or shell also made of polypropylene, the three elements coupling together to form said main body, with the special feature that these elements are affected on their smaller faces by holes (7-7'-7'') coinciding with each other, for the passage of a rivet and an O-ring in which the ends of the handle (8) are finished off.

For its part, the lid is also made up of three layers, an outer layer (1) as a shell made of polypropylene, an intermediate core (2) made of EPS, and an inner layer (3) or shell also made of polypropylene base, coupling these three layers together as it happened with the main body of the thermal bag.

The handle (8) will preferably be made of leather, and may incorporate means to adjust its length.

Both the main body and the lid adopt a slightly curved convex configuration on their external face, although the internal chamber that defines the inner layer (6) will present a constant horizontal section throughout its entire height.

According to figures 4 to 6, the bag is complemented by a series of containers that can be stacked together, based on a container body (9), and a top closure lid (10), containers that have plant dimensions according to the internal and constant horizontal section of the chamber that is defined in the bag, presenting these containers a submultiple height of the height of said chamber in which they are inserted stacked, which allows tightly stacking within the bag, a number default of containers with a use of storage space of 100% against what happens with conventional thermal bags.

Finally, it only remains to point out that these containers will include a perimeter relief (11) on their lid (10) intended to fit into a complementary recess (12) established on the underside of the base of said container, as can be seen in the enlarged detail of figure 6, thus achieving an extremely stable stacking.
