A liquid petroleum gas cylinder having a hollow plastic leg (2) that is secured to a single part of the inner surface of the metal body (1).

Description

BOUTEILLE DE GAZ DE PETROLE LIQUEFIE A PIED CREUX EN MATIERE PLASTIQUE LIQUEFIED PETROLEUM GAS BOTTLE WITH HOLLOW FOOT IN PLASTIC MATERIAL
La présente invention se rapporte aux bouteilles destinées à contenir des gaz de pétrole liquéfié.The present invention relates to bottles intended to contain liquefied petroleum gases.
Ces bouteilles sont en général en matériau métallique tel qu'en acier ou en aluminium.These bottles are generally made of metallic material such as steel or aluminum.
Si ces matériaux sont un excellent choix pour la réalisation de récipients sous pression, ils présentent, du fait de leur dureté même, des inconvénients, en particulier lorsque ces récipients sont utilisés à l'intérieur des appartements, car leurs pieds peuvent soit endommager les carrelages, soit rayer les planchers.If these materials are an excellent choice for the realization of pressure vessels, they present, because of their very hardness, disadvantages, in particular when these vessels are used inside apartments, because their feet can either damage the tiles , or scratch the floors.
Pour y pallier le FR 2 704 931 propose une bouteille à gaz résistant à la pression, qui n'endommage pas l'intérieur des appartements parce qu'elle comporte en bas un rebord annulaire plein collé.To compensate for this, FR 2 704 931 offers a pressure-resistant gas cylinder, which does not damage the interior of the apartments because it has a full glued annular rim at the bottom.
Pour faciliter le cryoformage, le DE 87 11 147 U décrit une bouteille de gaz de pétrole liquéfié comprenant un goujon fileté métallique issu du centre du fond du corps et qui coopère avec un écrou pour bloquer un piétement en matière plastique s'appliquant sur tout le fond du corps. Le GB 1 358 699A décrit un tonnelet de bière muni d'un jable creux, protecteur, en matière plastique, qui lui permet de mieux résister aux chocs.To facilitate cryoforming, DE 87 11 147 U describes a bottle of liquefied petroleum gas comprising a metallic threaded stud coming from the center of the bottom of the body and which cooperates with a nut to block a base of plastic material applying to the whole body background. GB 1 358 699A describes a beer keg provided with a hollow protective rim, made of plastic, which allows it to better withstand shocks.
L'invention vise l'utilisation d'un récipient comportant un corps métallique et un pied creux en matière plastique fixé à une partie seulement de la face inférieure du corps par des moyens de fixation d'une matière métallique à une matière plastique, comme bouteille de gaz de pétrole liquéfié en vue d'éviter la présence d'eau de condensation sous la face inférieure du corps.The invention relates to the use of a container comprising a metal body and a hollow plastic foot fixed to only part of the underside of the body by means of fixing a metal material to a plastic material, as a bottle. liquefied petroleum gas in order to avoid the presence of water of condensation under the lower face of the body.
Comme le pied est creux, on gêne le moins possible les échanges thermiques et on évite ainsi sur le bas du corps la présence d'eau de condensation (puisque le fond d'une bouteille de gaz de pétrole liquéfié peut atteindre une température très basse, à la différence d'un tonnelet de bière) qui s'en détache et stagne ensuite sur le sol et le salit.As the foot is hollow, the heat exchange is hindered as little as possible and the presence of condensation water is avoided on the lower body (since the bottom of a bottle of liquefied petroleum gas can reach a very low temperature, unlike a keg of beer) which detaches from it and then stagnates on the ground and dirty it.
Comme matière plastique, on peut notamment utiliser du polyéthylène haute densité. On peut coller le pied au corps, mais on préfère de beaucoup, pour ne pas avoir à effectuer une opération chimique de collage que l'on maîtrise mal dans l'industrie métallurgique et qui peut laisser des traces sur la bouteille, souder un goujon fileté au corps, y enfiler le pied et l'y maintenir par un écrou.As plastic material, it is possible in particular to use high density polyethylene. We can stick the foot to the body, but we much prefer, so as not to have to carry out a chemical bonding operation that is poorly mastered in the metallurgical industry and which can leave marks on the bottle, weld a threaded stud. to the body, thread the foot into it and hold it there with a nut.
De préférence, les pieds sont distincts en étant par exemple au nombre de deux ou de trois, et sont séparés les uns des autres par des intervalles dégagés qui facilitent les échanges thermiques entre le fond froid de la bouteille et l'atmosphère ambiante. Le point le plus bas du corps, qui est le plus froid, est aussi dégagé.Preferably, the feet are distinct, being for example two or three in number, and are separated from each other by clear intervals which facilitate the heat exchanges between the cold bottom of the bottle and the ambient atmosphere. The lowest point of the body, which is the coldest, is also clear.
Au dessin annexé, donné uniquement à titre d'exemple : la figure 1 est une vue partielle en coupe d'une bouteille de gaz de pétrole liquéfié suivant l'invention, et la figure 2 est une vue semblable à la figure 1 d'une variante préférée.In the accompanying drawing, given solely by way of example: FIG. 1 is a partial sectional view of a bottle of liquefied petroleum gas according to the invention, and FIG. 2 is a view similar to FIG. 1 of a preferred variant.
La bouteille représentée à la figure 1 comprend un corps 1 sensiblement de révolution en aluminium sous la face inférieure de laquelle et sur le pourtour de laquelle sont collés par une couche 3 de colle deux pieds 2 en polyéthylène. Les pieds 2 sont creux comme l'indique la cavité 4 et sont collés à distance du point central le plus bas du fond du corps 1. Chaque piedThe bottle shown in Figure 1 comprises a body 1 substantially of revolution in aluminum under the underside of which and on the periphery of which are bonded by a layer 3 of glue two feet 2 of polyethylene. The feet 2 are hollow as indicated by the cavity 4 and are glued at a distance from the lowest central point of the bottom of the body 1. Each foot
2 s'étend sur 90° environ d'une circonférence du corps 1 et les deux pieds 2 laissent entre eux deux intervalles dégagés du corps 1 de 90° chacun sur la circonférence.2 extends over approximately 90 ° from a circumference of the body 1 and the two feet 2 leave between them two clear intervals of the body 1 of 90 ° each on the circumference.
A la figure 2, deux goujons 5 sont issus du bas du corps 1 en acier de la bouteille en y étant soudés. A l'aide d'un écrou 6 se vissant sur ce goujon 4, on peut, après avoir enfilé le pied 2, par un trou qui y est ménagé, sur le goujon 5, retenir le pied 2 . In FIG. 2, two studs 5 come from the bottom of the steel body 1 of the bottle while being welded to it. With the aid of a nut 6 screwed onto this stud 4, it is possible, after having threaded the foot 2, through a hole made therein, on the stud 5, to retain the foot 2.
