Description

ARTIFACT FOR LIGHTING BARBECUE COALS,

DESCRIPTION

The present invention relates to a truncated cone in corrugated cardboard for burning barbecue coals.

To date, the most commonly used products for lighting barbecue coals are:

the. lighters, made from petroleum derivatives;

ii. fire lighters, made from sawdust and paraffin;

Hi. Liquid firelighters.

For all the aforementioned products, it is necessary to spend some time (which cannot be determined a priori) to fuel the combustion of the coals. The means used for this purpose are the most varied and, in some ways, the most imaginative. Among these we list:

iv. pieces of cardboard, plastic plates and other makeshift means used as a fan;

v. fans, hair dryers, turbines and other tools useful for creating air currents;

you. flamethrowers and the like.

It should be emphasized that the use of products i, ii, iii must necessarily be combined with one of the means described in points iv, v, vi; in fact, if the ignition of the combustion generally occurs through products i, ii, iii, the combustion of all the coals takes place with the aid of one of the means listed in points iv, v, vi.

For example, it is common to observe the ignition of coals by means of fire lumps (of any type) and the aid of one of the makeshift means used as a fan.

Therefore, to date, for the lighting of barbecue coals using the products / means mentioned above, the presence of the person lighting the coals is strictly necessary; presence that translates into fatigue and waste of time.

The artifact for the combustion of barbecue coals, object of the invention, solves these problems by providing the ignition of the coals in a simple, quick, economical, clean and non-invasive way.

Specifically, the invention is a hollow truncated cone (Fig. 1), made of corrugated cardboard, where B is the hole constituting the minor base and C is the hole constituting the major base; the slope, identified by the angle a, which the apothem (a) forms with C, allows the coals to be supported on the walls of the truncated cone in such a way that, between the coals themselves, the necessary space is created to passing convective currents that feed the combustion autonomously and without the intervention of the person who is lighting the fire. This slope is optimal with an angle a greater than 45 °.

The type of cardboard recommended for the manufacture of the truncated cone is corrugated cardboard as it has been seen to have the following properties:

- easy flammability;

right consistency in supporting the coals in the combustion phase; lower environmental impact compared to other products / vehicles present in the state of the art.

To facilitate the ignition of the aforementioned artifact, it is possible to apply a fuse that rises from the lower part of the truncated cone until it comes out of the hole constituting the minor base, allowing it to be switched on from the bottom upwards, physically more efficient for the exploitation of convection currents.

The recommended procedure for igniting coals using this product is as follows (Fig. 2):

1) place the truncated cone on the barbecue or on the surface chosen to light the coals (Fig. 2a);

2) lay the coals along the walls of the truncated cone so that it is uniformly surrounded by the coals (Fig. 2b);

3) turn on the truncated cone (Fig. 2c);

4) wait until all the coals are on fire (Fig. 2d);

5) spread the coals evenly on the chosen surface (Fig.

This procedure for using the product is the recommended one as it exploits the key mechanism of combustion.

In fact, combustion is a chemical reaction fueled by thermal convection, which involves the oxidation of a fuel by a comburent (in this case by the oxygen present in the air). The products of combustion and the portion of air depleted of oxygen heated by the flame are lighter and rise in the gravitational field of the earth, being replaced in the lower part by cold air which still contains oxygen and feeds the combustion (Fig. 3). This is the physical principle that is exploited by the product: if the air cannot circulate and renew itself, combustion ends in a very short time; and it is for this reason that, when the coals are lit with the other products present in the state of the art, the circulation of the air must be forcedly induced from the outside in a continuous way.

Among the obvious industrial applications that this product has, it was also thought of a possible sale of the same combined with specific barbecue products, such as the classic bags of coal.

Finally, it was thought that the product could be equipped with paper gloves, obtaining two results:

to prevent whoever lights the fire from getting their hands dirty by placing the coals along the walls of the artifact;

allow those who light the fire to take off the paper gloves, once the coals have been placed, and use them to light the cardboard product.

Claims (3)

CLAIMS 1) Artifact for the ignition of truncated cone-shaped barbecue coals, hollow, made of corrugated cardboard, comprising two holes which constitute the major base (C) and the minor base (B), and an apothem (a) which forms with the base C an angle (a) greater than 45 °. 2) Artifact for lighting barbecue coals according to claim 1, characterized in that it has a fuse applied to the surface of the truncated cone. 3) Product for lighting barbecue coals according to claims 1 and 2, characterized in that the lateral surface has homogeneously small holes.
