Definitions

• the present invention relates to a protective cap for a container and a container provided with such a cap.
• the invention relates more particularly to a protective cap for a fluid container, in particular for a pressurized gas bottle, comprising a casing body and a ring forming an interface for mounting the casing body on the container.
• NF E29-640 The protection against shocks and various attacks of valves or pressure-reducing valves fitted to pressurized fluid cylinders is generally performed by an accessory called a cap which can be "open” or “closed” (see NF E29-640 standard).
• NF E29-640 standard The general characteristics and the performances of these hats are described for example in standard NF EN 962.
• a closed cap provides complete valve protection when in place but must be removed to provide access to the faucet. Thus, the closed cap no longer protects the valve when the bottle is in use.
• Open hats are relatively simple when designed to protect conventional faucets.
• the caps are more sophisticated for valves with integrated regulators (RDI) because of their clearances allowing access to the controls and the visibility of manometers (see for example the document FR 2 774 452 A1).
• RTI integrated regulators
• the design of a hat must take into account several sometimes contradictory constraints. Thus, to ensure its role of protection while allowing access to the valve and ensuring good ergonomics of use (for the transport of the bottle as for filling or withdrawal of the fluid), the hat must be the most encompassing possible.
• the cap must be very open and / or removable.
• a removable cap is interesting for the maintenance of the tap but also for the maintenance of the hat itself (painting, cleaning, repair or replacement operations).
• the installation and removal of the cap must be relatively simple and the attachment must be sufficiently reliable to prevent loosening or loss of the cap during handling and transport.
• the cap To allow access to controls and visibility of manometers or other components, the cap must be positioned precisely in height as angularly relative to the valve.
• the hat must accommodate the type of fastener available on the bottle it equips (such as for example a "collar" according to standard NF EN 962).
• fasteners for the protective caps smooth collars, threaded collars with different diameters (in particular 78 mm and 80 mm).
• the collars generally have an outer diameter greater than the space envelope of most conventional faucets. This allows to mount the cap on a tap already mounted on the container.
• RDI integrated regulator valves
• US 4,880,134 discloses a smooth protective cap that attaches to its container by means of a threaded adapter ring. This solution is however not suitable for taps whose spatial envelope does not enter the diameter of the adapter ring.
• the cap can be made in two parts from pinching a smooth collar.
• This solution is not suitable for threaded flanges and is only suitable for a single flange profile (diameter and height).
• the protective cap which is also in accordance with the generic definition given in the preamble above, is essentially characterized in that the ring is split, ie it has a single opening on its circumference. for its introduction or withdrawal relative to a container, the opening the ring being provided to form, during installation or removal of the ring, a passage for a portion or section of a container or a member mounted on a container such as a tap.
• embodiments of the invention may include one or more of the following features:
• the ring has an elasticity to allow an enlargement and / or a temporary shrinkage of the opening during insertion and / or withdrawal,
• the end of the ring located substantially diametrically opposite the opening has a weakened and / or deformed zone relative to the rest of the ring
• the ring has an inner surface intended to be mounted on an outer surface of a container and an outer surface intended to cooperate with a surface of a rollover body for mounting the latter on the container, the inner surface of the ring being smooth or having hooking reliefs such as a tapping for cooperating with a conjugate surface of a container,
• the outer surface of the ring comprises a hooking or positioning profile designed to cooperate with a complementary profile of a surface of the cowling body
• the outer surface of the ring comprises at least one hollow and / or one relief
• the casing body comprises at least two parts capable of being secured,
• the casing body comprises at least two parts adapted to be secured so as to grip the ring on a container,
• the ring is dimensioned so as to have a clearance with respect to the external dimensions of the collar
• the ring forms an open ring
• the at least two parts of the casing body comprise fastening means of the flange and screw type
• the at least two parts of the casing body comprise openings provided for visibility and / or access to organs located inside the cap,
• the at least two parts of the casing body form a cage, preferably a metal cage,
• the ring comprises metal and / or a metal alloy and / or a plastic-type material.
• the casing body can be fixed on the flange by means of an interface comprising a split ring whose inner surface is threaded to cooperate with the thread of the flange.
• the outer profile of the ring is a surface of revolution which cooperates with a complementary profile located in the inner surface of the cap or casing body.
• the slot of the split ring is of a width dimensioned such that said ring can be put in place while the tap or the integrated regulator valve (RDI) is already installed on the bottle.
• the flange is threaded and the split ring threaded. It is thus possible to screw the ring on the flange to position it at the ideal height for the relative positioning of the cap and the tap or RDI.
• the cap can be split into at least two parts that are first assembled without particular tightening on the ring. This allows to angularly position the cap relative to the valve. It is then necessary to tighten the assembly of the different parts of the cap or casing body to concomitantly block the cap on the split ring and the split ring on the collar of the bottle.
• the split ring can be machined with a slight clearance with respect to the collar which simplifies its machining and implementation. This game can be caught when tightening the rollover body.
• the inertia of the split ring can be reduced locally, for example in the region diametrically opposite to its slot. For this purpose, it is possible to practice a notch and / or piercing that the skilled person will have available to reconcile its elastic efficiency and ease of obtaining.
• the same hat can be mounted on split rings of different shapes or internal sizes.
• the same split ring can also receive different hats. This can make it possible to renew casing bodies without changing the split mounting interface ring.
• the cap can be used with smooth collars by adopting adapted split rings accordingly.
• the fineness and accuracy of the height positioning of the ring on the flange are slightly less compared to the solution in which the split ring is threaded and screwed onto a threaded flange.
• differences in height can be corrected either by the use of different split rings if the differences are generic or by the use of slotted shims like the ring and introduced under it to obtain the desired height dimension.
• Another solution may be to use split rings having an outer profile off-center with respect to the thickness. That is, the protruding or recessed part of the outer surface of the ring is closer to one of the flanks (upper or lower) of the ring than to the other flank (lower or upper) of the ring. Ring.
• the cap By mounting the ring with the flank raised to the top, the cap will be mounted in a relatively high position. Conversely, by raising the raised flank upwards, the hat is mounted in a relatively low position.
• a template with different notches can be made easily.
• automatic metrology means can guide the operator.
• FIG. 1 represents a perspective view of the upper part of a pressurized gas cylinder provided with an integrated pressure reducing valve and without a protective cap,

• FIG. 1 represents a bottle 1 of pressurized gas equipped with an integrated regulator valve 2 comprising, conventionally, control means and manometers.
• a slotted ring 3 is presented in a position allowing its implementation by translation around the flange 4 of the bottle 1 (arrow T). More specifically, the ring 3 can be inserted or threaded around the valve and / or at the top of the flange 4 of the bottle 1 via a translation of the ring 3 in a direction substantially perpendicular to the vertical axis of the bottle 1. C that is to say that the ring 3 can be placed around the base of the valve 2 or at the top of the collar 4 in a direction substantially transverse to the axis of the bottle 1.
• the inner surface 23 of the ring 3 is threaded to cooperate with a conjugated thread formed on the collar 4.
• the outer surface 33 of the ring 3 comprises a peripheral rib intended to cooperate with a conjugate groove formed on an inner surface of a body cowling intended to be mounted on the ring 3 (see below).
• the width of the slot 13 of the ring 3 is dimensioned to allow the passage of the valve through the slot 13 towards the inside of the ring 3.
• the dimensions of the ring 3 can be determined with enough clearance to make the ring 3 easy to screw. Indeed, at the end of assembly of the cap, the ring 3, which has a certain elasticity due to its slot 13, will be tight on the flange 4 and the game will be caught.
• FIGS. 4 and 5 illustrate the positioning of the two half-caps 5, 6 which will be tightened on the ring 3 split by two screws 7.
