Description
La présente invention concerne une veilleuse à combustible liquide, tel que l'huile, et mèche incorporés.The present invention relates to a pilot liquid fuel, such as oil, and wick incorporated.
Jusqu'à présent, pour allumer une veilleuse à huile il faut disposer d'un récipient adéquat dans lequel on doit verser l'huile, ainsi qu'éventuellement de l'eau pour soulever la couche d'huile jusqu'à sensiblement le niveau de l'ouverture du récipient, puis on doit tremper dans le récipient une mèche supportée par un flotteur.So far to light an oil pilot you must have a suitable container in which to must pour oil, and possibly water to lift the oil layer to substantially the level of the opening of the container, then we must soak in the container a wick supported by a float.
Mais la réalisation d'une telle veilleuse est relativement longue, peu pratique et conduit souvent à l'obtention d'une flamme de qualité médiocre, car il est difficile de régler la longueur de la mèche qui doit tremper dans le combustible et celle qui doit dépasser à l'extérieur. De plus, une telle veilleuse n'est pas transportable sans précaution, car les liquides qu'elle contient risquent de déborder.But the realization of such a night light is relatively long, inconvenient and often leads to obtaining a poor quality flame because it is difficult to adjust the length of the wick which must soak in the fuel and the one that must exceed outside. In addition, such a night light is not transportable without care, because the liquids it contains may overflow.
On connaít d'autre part, par le brevet DE-36 00 608, un récipient de combustion fermé à une extrémité et dont l'autre extrémité reçoit un couvercle conique en métal terminé à son extrémité par un tube de petit diamètre . Avant la fixation du couvercle, le récipient est rempli d'un liquide combustible de viscosité élevée, tel que cire ou paraffine. Une mèche trempant dans le liquide passe à travers ledit tube, où elle est maintenue par des saillies résultant d'un grenage formé à travers la paroi latérale du tube. L'étanchéité du récipient est obtenue en trempant l'extrémité du tube dans un bain de cire solide chauffée. Il se forme alors autour du tube une couche de cire qui, en se solidifiant, forme un bouchon obturateur.On the other hand, we know from patent DE-36 00 608, a combustion vessel closed at one end and of which the other end receives a conical metal cover terminated at its end by a small diameter tube. Before fixing the lid, the container is filled a combustible liquid of high viscosity, such as wax or paraffin. A wick dipping in the liquid passes through said tube, where it is held by protrusions resulting from a peening formed through the wall side of the tube. The tightness of the container is obtained by soaking the end of the tube in a solid wax bath heated. A layer of wax which, when solidifying, forms a sealing plug.
Toutefois, l'étanchéité d'un tel récipient est imparfaite car le bouchon de cire risque de fondre ou d'être arraché accidentellement. De plus, le couvercle conique risque de se détacher du récipient.However, the tightness of such a container is imperfect because the wax plug may melt or to be accidentally torn off. In addition, the cover conical may come off the container.
On connaít également par le brevet US-4 511 952, une lampe comprenant une mèche incorporée. Toutefois, cette lampe n'est pas prête à l'utilisation, car on doit y introduire de l'huile. De plus, cette lampe n'est pas étanche, car elle comporte un orifice ouvert pour l'introduction de l'huile.Also known from US-4,511,952, a lamp comprising an incorporated wick. However, this lamp is not ready for use, as it must be introduce oil. In addition, this lamp is not waterproof because it has an open hole for introducing the oil.
On connaít enfin par le modèle d'utilité DE-U-92 12 537 une veilleuse selon le préambule de la revendication 1. Dans cette veilleuse, l'ampoule est en métal et la mèche fait saillie à travers l'ouverture située à l'extrémité supérieure de l'ampoule. Pour assurer l'étanchéité à ladite ouverture, il est prévu, selon ce document, de coiffer la mèche au moyen d'un capuchon indépendant en verre, qui est collé ou soudé sur l'extrémité de l'ampoule.We finally know by the utility model DE-U-92 12 537 a pilot light according to the preamble of claim 1. In this night light, the bulb is made of metal and the wick protrudes through the opening at the end upper part of the bulb. To seal against said opening, it is planned, according to this document, to cap the wick by means of an independent glass cap, which is glued or soldered to the end of the bulb.
Le corps de la veilleuse est donc réalisé en deux parties qui doivent être assemblées, à savoir l'ampoule et le capuchon. Le procédé de fabrication de cette veilleuse est relativement délicat puisqu'il comporte l'opération de la manipulation d'un capuchon de faibles dimensions et celle de son collage à l'ampoule. Lors du collage, on doit veiller à ce que la paroi du capuchon soit dans la continuité de celle de l'ampoule.The pilot's body is therefore made in two parts that need to be assembled, namely the bulb and Hood. The manufacturing process of this night light is relatively delicate since it involves the operation of handling a small cap and that of its bonding to the bulb. When bonding, care must be taken the wall of the cap is in continuity with that of the bulb.
De plus, lors de l'utilisation, il n'est pas facile de détacher le capuchon en entier du fait qu'il est collé fermement à l'ampoule. On doit donc soit le casser, au risque de laisser des débris collés à l'ampoule, soit l'éliminer par brûlage, ce qui laisse des traces noires peu esthétiques sur l'ouverture de l'ampoule.In addition, during use, it is not easy to detach the entire cap from the fact that it is glued firmly to the bulb. So we must either break it, at may leave debris stuck to the bulb, or burn it off, leaving little black marks aesthetics on the opening of the bulb.
En outre, du fait que l'ampoule est en métal, il n'est pas possible de voir au travers le niveau du combustible qu'elle contient.In addition, because the bulb is made of metal, it is not not possible to see through the fuel level it contains.
La présente invention remédie à ces inconvénients en proposant une veilleuse selon la partie caractérisante de la revendication 1.The present invention overcomes these disadvantages by offering a night light according to the characterizing part of the claim 1.
A l'utilisation, il suffit de briser le goulot et de dégager de l'étranglement l'extrémité de la mèche. La mèche peut alors être allumée sans aucune autre manipulation. On obtient ainsi une flamme de bonne qualité dont la durée dépend de la contenance de l'ampoule.In use, it is enough to break the neck and release the end of the wick from the constriction. The wick can then be switched on without any other manipulation. We thus obtains a good quality flame whose duration depends on the capacity of the bulb.
Un mode de réalisation de l'invention sera décrit à présent en regard de l'unique figure annexée qui représente une vue en coupe de la veilleuse fermée.An embodiment of the invention will be described in present next to the single attached figure which represents a sectional view of the closed pilot.
La veilleuse a une forme générale d'ampoule
pharmaceutique et comprend un corps renflé 1, par exemple
cylindrique, qui se prolonge à une extrémité par un goulot
8. Celui-ci peut être cassé à sa base le long d'une ligne de
rupture 2 et se termine par une pointe fermée 3 qui présente
un étranglement 4 au-dessus de la ligne de rupture 2.The night light has a general bulb shape
pharmaceutical and includes a swollen body 1, for example
cylindrical, which is extended at one end by a
A son autre extrémité, le corps 1 se termine par une embase qui peut être plate, de façon à ce que l'on puisse poser la veilleuse sur un support plat, ou avoir un profil à section décroissante, par exemple en escalier 5, de manière à pouvoir adapter la veilleuse sur des supports de diamètres variables.At its other end, the body 1 ends in a base which can be flat, so that we can place the pilot on a flat support, or have a profile to decreasing section, for example in staircase 5, so to be able to adapt the pilot light on variable diameters.
Lors de sa fabrication, la veilleuse reçoit une dose de combustible liquide 7, tel que l'huile, jusqu'à un niveau légèrement inférieur à celui de la ligne de rupture 2 et une mèche 6. Celle-ci s'étend sur toute la hauteur du corps et du goulot. Son extrémité supérieure est pincée par l'étranglement 4, de sorte que la mèche ne risque pas de tomber au fond du corps de la veilleuse pendant son transport et lors des manipulations avant son ouverture.During its manufacture, the pilot receives a dose liquid fuel 7, such as oil, up to a level slightly below that of the breaking line 2 and a wick 6. This extends over the entire height of the body and neck. Its upper end is pinched throttle 4, so that the wick does not risk fall to the bottom of the pilot's body during transport and during handling before opening.
Le corps et le goulot sont réalisés en une seule pièce, de préférence en une matière transparente ou translucide, par exemple en verre ou en une matière thermoplastique. Lors de sa fabrication, après avoir rempli la veilleuse de combustible liquide et y avoir mis la mèche, on ferme le goulot en chauffant sa pointe jusqu'à sa température de ramollissement, ce qui permet de la souder et d'obtenir une bonne herméticité de la veilleuse.The body and the neck are made in one piece, preferably of a transparent material or translucent, for example made of glass or a material thermoplastic. During its manufacture, after having filled the pilot with liquid fuel and put it there the wick, we close the neck by heating its tip to its softening temperature, which allows solder it and get good airtightness of the night light.
Il va de soi que la veilleuse selon l'invention peut revêtir différents aspects, formes et couleurs et peut contenir divers types de combustibles liquides donnant une bonne flamme. Une autre application intéressante est celle des huiles parfumées qui, en brûlant, dégagent une bonne odeur.It goes without saying that the pilot light according to the invention can take on different aspects, shapes and colors and can contain various types of liquid fuels giving good flame. Another interesting application is that scented oils which, on burning, give off a good odour.
