Description

Bouteille de fluide sous pression  Bottle of fluid under pressure
La présente invention concerne une bouteille de fluide sous pression. The present invention relates to a bottle of pressurized fluid.
L'invention concerne plus particulièrement une bouteille de fluide sous pression comprenant un orifice dans lequel est disposé un robinet, la bouteille comprenant un chapeau de protection du robinet monté sur l'extrémité supérieure de la bouteille, le chapeau comprenant au moins une paroi définissant une structure rigide délimitant un volume de protection autour du robinet, la bouteille comprenant un organe d'affichage d'une information représentative de la quantité de fluide contenue dans la bouteille, l'organe d'affichage comprenant au moins deux états d'affichage distincts symbolisant respectivement deux quantités distinctes de fluide contenues dans la bouteille.  The invention relates more particularly to a bottle of pressurized fluid comprising an orifice in which a valve is arranged, the bottle comprising a valve protection cap mounted on the upper end of the bottle, the cap comprising at least one wall defining a rigid structure delimiting a volume of protection around the valve, the bottle comprising a display member of information representative of the quantity of fluid contained in the bottle, the display member comprising at least two distinct display states symbolizing respectively two distinct quantities of fluid contained in the bottle.
Pour indiquer à l'utilisateur d'une bouteille de fluide sous pression l'autonomie restante, il est connu de prévoir un manomètre sur le robinet de la bouteille. Ce manomètre est généralement monté sur un robinet et protégé avec le robinet par un chapeau de protection. Pour être visible par l'utilisateur le manomètre est généralement accessible via une ouverture du chapeau de protection.  To indicate to the user of a bottle of fluid under pressure the remaining autonomy, it is known to provide a pressure gauge on the valve of the bottle. This manometer is usually mounted on a tap and protected with the tap by a protective cap. To be visible to the user the manometer is generally accessible via an opening of the protective cap.

- la figure 9 représente une vue de côté, schématique et partielle, illustrant un détail de la bouteille des figures 5 à 8 illustrant un exemple possible de plusieurs informations affichables au niveau du chapeau.  - Figure 9 shows a side view, schematic and partial, illustrating a detail of the bottle of Figures 5 to 8 illustrating a possible example of several information displayable at the cap.
La bouteille 6 de fluide sous pression (par exemple de gaz sous pression) illustrée à la figure 1 comprend classiquement un orifice dans lequel est disposé un robinet 7. Le robinet est muni d'un circuit 17 fluide comprenant au moins une vanne.  The bottle 6 of pressurized fluid (for example gas under pressure) illustrated in Figure 1 typically comprises an orifice in which is disposed a valve 7. The valve is provided with a fluid circuit 17 comprising at least one valve.
La bouteille 6 comprend un chapeau 1 de protection du robinet 7 monté rigidement sur l'extrémité supérieure de la bouteille 6 (par vissage et/ou serrage et/ou tout autre moyen approprié).  The bottle 6 comprises a cap 1 for protecting the valve 7 rigidly mounted on the upper end of the bottle 6 (by screwing and / or clamping and / or any other appropriate means).
Le chapeau 1 comprend classiquement au moins une paroi 2, 3 définissant une structure rigide délimitant un volume de protection autour du robinet 7.  The hat 1 conventionally comprises at least one wall 2, 3 defining a rigid structure delimiting a volume of protection around the tap 7.
La bouteille 6 comprend également un organe 8, 9 d'affichage d'une information représentative de la quantité de fluide contenue dans la bouteille 6 (pression courante, et/ou quantité restante et/ou autonomie restante...).  The bottle 6 also comprises a member 8, 9 for displaying information representative of the quantity of fluid contained in the bottle 6 (current pressure, and / or remaining quantity and / or remaining autonomy ...).
A cet effet, le ou les organes 8, 9 d'affichage peuvent comprendre au moins deux états d'affichage distincts symbolisant respectivement deux quantités distinctes de fluide contenues dans la bouteille 6.  For this purpose, the display member (s) 8, 9 may comprise at least two distinct display states respectively symbolizing two distinct quantities of fluid contained in the bottle 6.
Selon une particularité avantageuse, cet organe 8, 9 d'affichage est situé sur la surface périphérique d'une portion de la paroi 2, 3 du chapeau 1 disposée autour du robinet 7 et formant une protection mécanique autour du robinet 7.  According to an advantageous feature, this display member 8, 9 is located on the peripheral surface of a portion of the wall 2, 3 of the cap 1 disposed around the valve 7 and forming a mechanical protection around the valve 7.
C'est-à-dire que l'organe 8, 9 d'affichage débouche sur la paroi externe du chapeau 1 , notamment latérale, de façon parfaitement visible pour un utilisateur.  That is to say that the display member 8, 9 opens on the outer wall of the hat 1, in particular lateral, in a manner perfectly visible to a user.
Le chapeau 1 comporte par exemple une première paroi 2 formant une portion tubulaire s'étendant entre d'une part une extrémité inférieure 4 du chapeau et, d'autre part, une extrémité supérieure 12. L'organe 8, 9 d'affichage est situé de préférence sur cette surface périphérique de ladite portion tubulaire (cf. également figures 2 et 5. Comme visible aux figures 2 et 5, la surface périphérique de ladite portion tubulaire formée par la première paroi 2 peut comporter un renfoncement, l'organe d'affichage 8, 9 étant situé et abrité au moins en partie dans ledit renfoncement. The cap 1 comprises for example a first wall 2 forming a tubular portion extending between on the one hand a lower end 4 of the cap and, on the other hand, an upper end 12. The display member 8, 9 is preferably located on this peripheral surface of said tubular portion (see also Figures 2 and 5. As shown in Figures 2 and 5, the peripheral surface of said tubular portion formed by the first wall 2 may comprise a recess, the display member 8, 9 being located and housed at least partially in said recess.
Comme illustré aux figures 1 et 5 à 9, l'organe d'affichage 9 s'étend de préférence sur plus de la moitié et de préférence sur toute la circonférence de portion tubulaire formée par la première paroi 2. C'est-à-dire l'organe 87 9 d'affichage s'étend autour du chapeau 1 autour de l'axe longitudinal de la bouteille 6. De cette façon, l'information est visible pour l'utilisateur sans nécessiter de tourner autour de la bouteille 6. As illustrated in FIGS. 1 and 5 to 9, the display member 9 preferably extends over more than half and preferably over the entire tubular portion circumference formed by the first wall 2. That is, say the display member 8 7 9 extends around the cap 1 about the longitudinal axis of the bottle 6. In this way, the information is visible to the user without having to turn around the bottle 6 .
Dans l'exemple des figures 2 à 4, l'organe 8 d'affichage comprend un ou plusieurs manomètres (à aiguille ou à affichage digital ou autre). Le manomètre 8 peut être logé dans la première paroi 2 tubulaire du chapeau 1 . C'est-à-dire que le corps du manomètre 8 traverse la première paroi 2 et comprenant une extrémité reliée au circuit 17 interne du robinet 7 en communication avec le volume de stockage du la bouteille 7 (à la même pression que dans la bouteille 6). L'afficheur du manomètre débouche lui vers l'extérieur sur le chapeau 1 , par exemple en étant orienté vers le haut comme représenté aux figures. Pour être visible à plusieurs mètres, l'affichage à aiguille classique peut être remplacé ou suppléé par un système de couleurs ou de contrastes.  In the example of Figures 2 to 4, the display member 8 comprises one or more manometers (needle or digital display or other). The pressure gauge 8 can be housed in the first tubular wall 2 of the cap 1. That is to say that the body of the manometer 8 passes through the first wall 2 and comprising an end connected to the internal circuit 17 of the valve 7 in communication with the storage volume of the bottle 7 (at the same pressure as in the bottle 6). The manometer display opens outward on the cap 1, for example by being oriented upwards as shown in the figures. To be visible at several meters, the classic needle display can be replaced or supplemented by a system of colors or contrasts.
Dans l'exemple des figures 2 à 4, l'organe 9 d'affichage comprend un écran digital et de préférence papier électronique (« e-paper ») configuré pour afficher un niveau relatif de pression ou de contenu de fluide dans la bouteille. Comme illustré, l'information affichée peut être un graphique à barres adjacentes ou autre dont le contraste et/ou la couleur des barres peut être commuté entre aux moins deux états distincts. Ces au moins deux états peuvent correspondre à des niveaux déterminés par exemple : plein/ presque vide, supérieure ou inférieur à au moins un seuil (le seuil pouvant être par exemple choisi entre de 5% à 50% de la quantité maximale stockée dans la bouteille 6).  In the example of Figures 2 to 4, the display member 9 comprises a digital screen and preferably electronic paper ("e-paper") configured to display a relative level of pressure or fluid content in the bottle. As illustrated, the displayed information may be an adjacent bar graph or the like of which the contrast and / or color of the bars may be switched between at least two distinct states. These at least two states may correspond to levels determined for example: full / almost empty, greater than or less than at least one threshold (the threshold may for example be chosen between 5% to 50% of the maximum quantity stored in the bottle 6).
Dans l'exemple des figures 5 à 8, l'affichage comprend trois barres horizontales adjacentes superposées verticalement qui définissent ainsi quatre niveau (trois barres, deux barres, une barre et aucune barre). Dans l'exemple de la figure 9 différents niveaux de contraste ou de couleur peuvent être prévus (jaune/vert/rouge/noir/blanc/incolore) sur des parties de l'afficheur 9 (de gauche à droite : vert ; orange et vert, rouge et orange ou rouge). In the example of Figures 5 to 8, the display comprises three adjacent horizontal bars vertically superimposed which thus define four level (three bars, two bars, a bar and no bar). In the example of Figure 9 different levels of contrast or color can be provided (yellow / green / red / black / white / colorless) on parts of the display 9 (from left to right: green, orange and green red and orange or red).
Comme illustré aux figures 7 et 8, l'organe 9 d'affichage (rigide ou flexible) peut être tubulaire ou replié pour être enfilé autour d'une portion cylindrique de la première paroi 2 du chapeau 1 .  As illustrated in Figures 7 and 8, the display member 9 (rigid or flexible) may be tubular or folded to be threaded around a cylindrical portion of the first wall 2 of the cap 1.
L'organe 9 d'affichage est monté sur la surface périphérique de la première paroi entre une butée inférieure 122 et une butée supérieure. La butée supérieure peut être formée par un anneau 22 assemblée sur l'extrémité supérieure de la première paroi 2 et formant un organe de maintien. Dans le cas où la première paroi cylindrique est en deux portions assemblées selon un plan vertical, cet anneau 22 peut être un moyen de maintien mécanique de ces deux portions (cf. figure 7).  The display member 9 is mounted on the peripheral surface of the first wall between a lower stop 122 and an upper stop. The upper stop may be formed by a ring 22 assembled on the upper end of the first wall 2 and forming a holding member. In the case where the first cylindrical wall is in two portions assembled in a vertical plane, this ring 22 may be a mechanical holding means of these two portions (see Figure 7).
L'organe d'affichage 9 peut être relié sans fil ou par voie filaire avec un organe de mesure de la pression dans la bouteille 7 (capteur de pression). Ce capteur de pression peut alternativement ou cumulativement être disposé en aval de la bouteille, c'est-à-dire au niveau d'un dispositif (robinet, machine) relié au robinet 7.  The display member 9 may be connected wirelessly or wired with a pressure measuring member in the bottle 7 (pressure sensor). This pressure sensor may alternatively or cumulatively be disposed downstream of the bottle, that is to say at a device (valve, machine) connected to the valve 7.
L'organe de mesure de pression peut comprendre un dispositif d'émission de données vers l'organe 8, 9 d'affichage qui, en réponse, affiche une information de contenu de fluide de façon fixe ou dynamique. Dans le cas où l'organe d'affichage 9 est un papier électronique, l'état stable de l'information affichée ne consomme pas d'énergie électrique et l'information peut être mise à jour dès que possible ou nécessaire.  The pressure measuring member may comprise a data transmission device to the display member 8, 9 which, in response, displays a fluid content information in a fixed or dynamic manner. In the case where the display member 9 is an electronic paper, the stable state of the displayed information does not consume electrical energy and the information can be updated as soon as possible or necessary.
Dans les exemples de réalisation non limitatifs des figures 2 à 8 le chapeau In the non-limiting exemplary embodiments of FIGS.
1 comprend une seconde paroi 3 disposée concentriquement de façon espacée autour de la première paroi 2 et délimitant une zone de protection de la première paroi (2) et de l'organe 8, 9 d'affichage. 1 comprises a second wall 3 disposed concentrically spaced around the first wall 2 and defining a protection zone of the first wall (2) and the display member 8, 9.
Comme illustré, la seconde paroi 3 comprend par exemple une portion annulaire 13 disposée concentriquement autour de la première paroi 2 et reliée à la première paroi via plusieurs bras 23 de liaison. De préférence, selon une direction verticale s'étendant entre les extrémités inférieure et supérieure du chapeau 1 , l'extrémité supérieure 12 de la première paroi 2 fait saillie au-dessus de la seconde paroi. As illustrated, the second wall 3 comprises for example an annular portion 13 disposed concentrically around the first wall 2 and connected to the first wall via a plurality of connecting arms 23. Preferably, in a vertical direction extending between the lower and upper ends of the cap 1, the upper end 12 of the first wall 2 projects above the second wall.
L'organe 8, 9 d'affichage est situé de préférence au moins en partie dans la portion de la première paroi 2 faisant saillie au-dessus de la seconde paroi 3. De cette façon, l'organe 8, 9 d'affichage est parfaitement visible latéralement et est tout de même protégé par la seconde paroi 3.  The display member 8, 9 is preferably located at least partly in the portion of the first wall 2 projecting above the second wall 3. In this way, the display member 8, 9 is perfectly visible laterally and is still protected by the second wall 3.
De préférence également, l'organe 8, 9 d'affichage est situé en retrait par rapport au plan P qui est tangent à la fois aux extrémités supérieures/latérales des deux parois 2, 3 (cf. figure 4). Ainsi, en cas de chute latérale sur le sol l'organe 8, 9 d'affichage est abrité et protégé par le chapeau 1 .  Also preferably, the display member 8, 9 is set back from the plane P which is tangent to both the upper / lateral ends of the two walls 2, 3 (see Figure 4). Thus, in the event of a lateral fall on the floor, the display member 8, 9 is housed and protected by the hat 1.
Bien entendu, en variante ou en combinaison, l'organe d'affichage peut être situé sur la seconde paroi 3, par exemple sur sa périphérie.  Of course, alternatively or in combination, the display member may be located on the second wall 3, for example on its periphery.
