Abstract

Portable container, which is specially designed to keep inside any liquid or solid food product, cold or hot, at a temperature close to its introduction within the same and for a considerable time, is characterized by being constituted by the functional combination of a body and a cover, in each of which an inner wall is established, of a thermal transmitting material, and an outer wall of a thermally insulating nature, determining among themselves an intermediate chamber both in the body and in the lid, hermetically closed, fully occupied by a liquid acting as a thermal accumulator.

Description

Portable container.

Object of the invention

The present invention relates to a container portable, specifically to a small container, capable of keeping any type of solid or liquid food, packaged or bulk, cooked or without cooking, in isothermal conditions, that is to say staying said hot or cold food, depending on what is required in each case.

The object of the invention is to achieve a structurally simple, easily manageable container, which also offer optimum performance from the point of view of thermal insulation, keeping the product housed in inside, at a temperature very close to the original, during A long period of time.

Background of the invention

Isothermal containers are known, as per example the classic portable refrigerators, trained to maintain cold its contents for a more or less long period of time. The functional philosophy of these refrigerators or containers is based, either in the introduction of ice inside, or in the introduction of cold accumulators, which constitute parts physically independent of the refrigerator itself, which must be frozen prior to its introduction therein and that, as is evident, they represent a significant loss of available space inside the fridge, to be able to accommodate in them Foods that you want to preserve technically.

Other types of containers, commonly called `` thermos '', they are based on configuring a container based of a double wall within which a camera is established in the one that the vacuum is practiced, so that in this case it is not It is necessary to introduce ice inside the thermos, nor effect a warm-up thereof, but the effect pursued it is achieved by the high thermal insulation coefficient of the container wall, but this solution is structurally complex, consequently expensive and with an accused and unfavorable disproportion between the volumetric occupation of the thermos and space useful of it.

Description of the invention

The portable container that the invention proposes solves the problem fully satisfactorily previously exposed, constituting a simple solution and effective.

To do this and more specifically said container is structured by a body and a lid, interacoplables by thread, with the special feature of that both body and lid have a double wall, determining of respective sealed chambers occupied by a liquid of thermal accumulation such as fresh water or salt water, which optionally it can be complemented with any product additive that improves its conditions as such an accumulator, constituting said chambers, as well as the liquid they contain, a high efficiency thermal transmission barrier, which prevents loss of calories, when it comes to maintaining a product hot, or else the loss of fridges when what is intended Keep it cold

In the first case and immediately before the use of the container, it will undergo a phase of heating, for example to the `` water bath '' or similar, while which in the second case will be introduced into the freezer of a refrigerator until the temperature of the latter is reached.

Specifically it is planned that the wall internal container is obtained based on a material thermal transmitter, such as aluminum or brass, while the outer wall is obtained based on a material heat insulating, such as polyurethane expanded, which is what really constitutes the barrier to thermal transmission, which occurs in any case at expense first of cooling or liquid heating content in the aforementioned cameras.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a side elevation view of a portable container made in accordance with the purpose of the present invention, which appears in a closed situation.

Figure 2.- Shows another elevation view side of the same container, now in cross section, of according to the cutting line A-B of Figure 1, and with its cover uncoupled from the body.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the container that the invention proposes is constituted by the functional combination of a body (1) and a cover (2), the first topped at the level of its mouth in a threaded neck (3) and the second provided with an internal thread and complementary (4), which ensure a stable and tight seal.

An internal wall (5) participates in the body (1) that as previously said will preferably be of aluminum, brass or other similar material, and an external wall (6), which in turn will be of a material with a high coefficient of thermal insulation, such as expanded polyurethane, with an appropriate density, defined between these inner walls (5) and external (6) a camera (7), waterproof, intended to be occupied entirely by fresh water, salt water or any of they mixed with an additive suitable for, as previously He said, boost your thermal accumulation capacity.

For its part in the lid (2) is established also an internal wall (5 ') and an external wall (6') of the same characteristics as the walls (5) and (6) above cited, also determinants of a waterproof chamber (7 '), occupied by the same liquid.

The container as a whole will present some dimensions such that it is able to receive within it, for example, a drinking can such as a beer can, a bottle or any other packaged beverage, but it can also house in inside a bulk drink, such as coffee, or any solid food such as fruits, pies, ice cream, fish, seafood, meats, etc.

When it is a cold product, which is desired keep in its temperature, the body (1) and the lid (2), duly independent, will be introduced within the freezer of a refrigerator or other similar cold source, up to freeze the liquid in the chambers (7-7 '), at which time the container is you will find in conditions of use, to introduce the product in question and close it, that is the coupling of its cover (2) to its body (1), so that said product will remain cold for a considerable time long.

If it is the opposite, that is to say keep a hot product, logically the freezing operation of the liquid existing in the chambers (7-7 ') is replaced by a heating operation, for example introducing the body (1) and the lid (2) in a container to the bathroom Maria, applying steam, etc., although this operation is not essential, the hot product will stay inside, it will produce the closure of the container, and this will also maintain the initial product temperature for a period of time considerably long.

Claims (3)

1. Portable container, which being specially designed to keep inside any liquid or solid food product, cold or hot, at a temperature close to that of its introduction into it and for a considerable time, is characterized by being constituted by means of the functional combination of a body and a cover, in each of which an inner wall, of a thermal transmitting material, and an outer wall of a heat-insulating nature are established, determining each other of an intermediate chamber both in the body and in the lid, tightly closed, fully occupied by a liquid acting as a thermal accumulator. 2. Portable container according to claim 1, characterized in that the internal partition of both the body and the lid is brass aluminum or other similar material, the constituent material of the external wall is expanded polyurethane or other similar material, and the liquid occupying the Chambers defined by them is fresh water, salt water or any of them mixed with an additive that enhances its performance as a thermal accumulator. 3. Portable container, according to previous claims, characterized in that its body is cylindrical, with a suitable capacity to house inside a boat, a bottle of drink or the like, and incorporates at the level of its mouth a threaded neck through which it receives to the complementary cover, establishing a tight seal.
