- FIG. 10 and 1 1 show partial schematic side views, illustrating examples of deformation of the cap during shocks or falls respectively in two separate orientations.
- the protective cap 1 schematically illustrated in Figure 1 comprises a rigid structure defining a central protection volume for a valve. This structure has a lower end 4 intended to be fixed on the upper end of a bottle of pressurized fluid, especially at the neck of a cylindrical generally cylindrical bottle comprising an end-shaped ogive. Conventionally, the hat 1 can be screwed and / or tightened at the neck of a bottle.
- the cap 1 comprises a first wall 2 forming a central tubular portion. In use position on a vertical bottle, this tubular portion extends vertically about an axis A.
- This tubular portion extends between on the one hand the lower end 4 of the cap and, on the other hand, an upper end 12.
- the upper end of the central tubular portion is open, that is to say that it defines an orifice 5 to access the internal volume of the tube.
- This orifice 5 may if necessary be closed by a removable cover.
- This internal volume to the tubular portion is intended to house a valve (see Figure 2).
- This valve can be a simple connector connection to the high pressure contained in a bottle 6.
- At least a portion of the tubular portion formed by the first wall 2 is cylindrical.
- the first wall 2 comprises for example a cylindrical upper portion (full or perforated) and a lower portion which flares towards the lower end 4 of the cap and which is intended to be attached to the upper end of a bottle.
- the cap 1 further comprises a second wall 3 disposed concentrically spaced around the first wall 2. This second wall 3 defines a protection zone of the first wall 2.
- the second wall 3 is for example spaced transversely from the first wall 1 by a distance preferably between 20 and 100mm, for example between 20 and 50mm, in particular to allow the passage of fingers or hands of a user.
- the first 2 and second 3 walls for example of metal and / or plastic material, are monobloc or rigidly fixed to each other (by molding, welding, assembly or any other suitable method).
- the second wall 3 preferably comprises an annular portion 13 disposed concentrically around (spaced apart) from the first wall 2 and connected to the first wall via several connecting arms 23.
- the connecting arms 23 are angularly distributed around the vertical axis A.
- the connecting arms 23 each comprise for example one end connected to the annular portion 13 and one end connected to the lower part of the first portion 2, in particular at the lower end 4 of the cap 1.
- Between two arms 23 adjacent the second wall may be perforated. That is to say that openings allow access to the first wall 2.
- This annular portion 13 thus forms an additional mechanical protection around the valve.
- this annular portion is also a manual gripping wheel for handling, rolling or tilting of the bottle.
- the upper end 12 of the first wall 2 projects above (beyond) the second wall 3.
- the upper end 12 of the first wall 2 protrudes above the second wall 3 over a distance of between 10 and 60 mm.
- the hat 1 according to the invention has a solid mechanical structure providing good protection for a faucet while allowing easy handling.
- the tubular end of the first wall 2 can also be manipulated for guiding, rolling or tilting the bottle 6.
- At least a portion of the peripheral surface of the first wall 2 may comprise a display member 8, 9 information representative of the amount of fluid contained in the bottle on which the cap is mounted.
- the display member 8, 9 comprising at least two distinct display states respectively corresponding to two distinct quantities of fluid (empty / full or two filling level above and below a threshold: 5% or 10% or 20% or any other appropriate value).
- the display member 8 may comprise a manometer displaying a pressure level or capacity (via a needle or a digital display or color (s)).
- the display member 8 opens at least partially on the first wall above the second wall 3. In this way, the information representative of the quantity of fluid stored in the bottle 6 is visible even at distance.
- the pressure gauge 8 can be integrated in the first wall 2 (through it).
- the pressure gauge 5 can be connected to the pressurized circuit of the valve which communicates with the inside of the bottle 6 to continuously read the pressure within the bottle 6.
- the display of pressure or content may be obtained by a pressure measuring member or other deportee that returns this information wirelessly or by wire to the pressure gauge 8 which displays it in a fixed or dynamic manner.
- the display member 9 comprises an electronic display, including an electronic paper ("e-paper").
- e-paper electronic paper
- This display 9 is preferably also placed on the outer surface of the first wall 2, for example in a circumferential housing slightly recessed towards the inside of the cap 1. In this way also, the display member 9 is perfectly visible (for example 360 degrees around the axis A) while being protected.
- this or these display members may be of the electronic and / or mechanical type and connected (s) by a gas or other network (capillary network for example) to the high pressure in the bottle or the tap 7.
- the display of the pressure or the content may be explicit or may be symbolized by color codes, contrasts, alpha-numerical symbols (see Figures 5 and 6: several adjacent bands darkened or not).
- color codes or shades of the same shade can symbolize several levels of filling.
- the information displayed may be that measured in the bottle by pressure measuring member or other remote or not, which returns this information wirelessly or wired to the body 9 displays in a fixed or dynamic manner.
- the display member 8, 9 is preferably disposed between the two walls 2, 3. More specifically, the display member is preferably set back from the plane P which is tangent to both the upper ends (and / or side) of the two walls 2, 3. In this way, the display member 8, 9 is always protected and sheltered in case of fall of the bottle 6 on the ground.
- the cap 1 may be formed of two or more parts of two parts (three, four ...) assembled to each other.
- first wall 2 and the second wall 3 form separate entities assembled with each other.
- the first wall 2 is for example positioned on the bottle 6 (around the tap) and the second wall 3 is attached to the first wall 2 and is fixed (for example by screwing) on the bottle 6. That is to say that the first wall 2 in the form of a tube is locked on the bottle 6 via the second wall 3 (for example in the form of a flywheel) which is screwed onto the neck of the bottle 6.
- first 2 and second 3 walls are also separate assembled entities.
- the second wall 3 is for example placed first on the end of the valve 6 and is then trapped by the first wall 2 which is fixed (preferably screwed) on the neck of the bottle 6.
- the second wall 3 is for example molded whereas the first wall 2 can be made by conventional turning.
- the first 2 and second 3 walls may optionally be made of respective different materials (metal / plastic ). It is thus possible to concentrate the machining recoveries on the part already manufactured by turning.
- a portion of the cap 1 may be rotatable around the central axis A. That is to say, a portion of the cap 1 can form a rotating knob facilitating its manual handling.
- the first wall 2 can be mounted free to rotate with respect to the second wall 3 and to the bottle 6.
- the second wall 3 can be rotatably mounted around the first wall 2 and the bottle 6.
- the upper end of the first wall 2 may comprise an annular piece mounted free to rotate about the axis A relative to the rest of the cap 1.
- the upper end of the first wall 2 may comprise a flange 102 extending radially outwardly of the cap 1 forming a gripping area. This flange 102 being optionally rotatable relative to the remainder of the hat 1.
- the structure according to the invention also allows a shock resistance (absorption of impact energy in case of a fall).
- the first wall 2 is deformed preferentially by widening and / or shortening (FIG. 10). Scheduled tears may even be provided on the first wall 2 via thinning or localized bending areas of the first wall 2 (for example on the model of the structure of "Molly pegs").
- the deformation and therefore the shock absorption is preferably ensured by the second wall 3 (for example via a elongation and / or flattening of the second wall (see Figure 1 1).
- the first wall and the tap 7 thus remain preserved.
