Definitions
- the present invention relates to a protective cap for a fluid container.
- the invention relates more particularly to a protective cap for a fluid container, in particular for the protection of a valve / expander device mounted on a pressurized gas cylinder, comprising at least two parts intended to be assembled together. other on the container so as to form a cowling.
- 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).
- 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).
- RDI integrated regulators
- 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 the controls and the visibility of pressure gauges 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 protective caps plain collars, threaded collars with different diameters.
- 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.
- a large number of valves, and in particular integrated regulator valves (RDI) have a spatial envelope greater than the outer diameter of the flanges.
- a known solution is to provide a removable cap that can be assembled on the bottle without disassembling the valve, that is to say a cap that can be mounted on the bottle after the tap.
- the cap consists of two substantially symmetrical wraparound half-caps or a single wrap-around piece intended to cooperate with a non-wrap-around connecting piece such as a fastening flange.
- the two parts forming the cap are for example assembled by screwing.
- a known solution is to provide a second operator to maintain the parts of the cap during their assembly by the first operator. This solution is however expensive on an industrial scale.
- Another solution is to provide means for temporarily holding the two parts of the cap, for example an adhesive tape or a link, during the screwing and then remove them.
- This solution is also neither economical nor appropriate on an industrial scale.
- Another solution is to provide means for maintaining conjugate on the two parts, for example elastic clip fastening systems, sized sufficiently to hold the two parts together during the actual assembly (screwing for example).
- This solution is however not suitable for hats made of metal. In the event that the means of Mating retention located on both parts are magnetization type, this can penalize the weight and cost of the cap.
- an object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the protective cap for a fluid container according to the invention is essentially characterized in that the two parts are mechanically linked by at least one linking system allowing limited relative movement between the parts.
- embodiments of the invention may include one or more of the following features:
- said cap in the mounted position, said cap comprises a lower portion and an upper portion aligned in a so-called elevation direction, and in that the linking system comprises a hinge axis common to both parts; the linking system comprises a single hinge axis common to both parts and substantially parallel or substantially perpendicular to the elevation direction,
- the linking system comprises two joints that are common to both parts; the geometric axis of the two common joints is substantially perpendicular to the elevation direction,
- At least one of the parts of the cap comprises at least one member able to temporarily urge and / or hold the parts in their assembled position to one another
- the organ or parts capable of soliciting / maintaining the parts in their assembled position to one another comprise one or more of the following: an elastic connection, a magnetization,
- the at least two parts intended to be assembled comprise two half-enveloping caps having substantially identical overall volumes or shapes.
- FIG. 1 shows a side view of a protective cap according to a first embodiment of the invention, in the unmounted position
- - Figure 2 shows a top view of the cap of Figure 1 in partially mounted position on a fluid bottle provided with an expansion valve and in which the top wall of the cap is not shown
- FIG. 3 represents a view from above of a protective cap according to a second exemplary embodiment of the invention, illustrating its mounting around an expansion valve
- FIG. 4 shows a side view of a protective cap according to a third exemplary embodiment of the invention, illustrating its mounting on a fluid bottle provided with an expansion valve
- FIG. 5 represents a view from above of the hat of FIG. 4 in position mounted on a fluid bottle provided with an expansion valve and with an enlarged detail
- the cap 1 has the general shape of a cylinder comprising a lower zone forming a base to be mounted on the neck of a bottle 4 (directly or via a fixing means intermediate such as a fixing ring not shown) and an upper zone in the form of a housing or shell intended to house a regulator valve 2.
- the shell may comprise one or more lateral ports 12 to access the valve 2 and has an upper wall comprising a central handling knob 11.
- the housing or protective shell is formed by a first portion 15 of the cap 1 connected by a hinge 7 to a second cap portion 16 forming a fastening flange in the form of a half-ring.
- the second part 16 is intended to cooperate with the base of the first part 15 to grip the neck of the bottle 4.
- the first 15 and second part 16 may comprise threaded orifices. adapted to coincide to allow their attachment to one another and the tightening of the assembly around the neck of the bottle 4.
- the two parts forming the cap 1 are rigidly connected (and preferably non-releasably) by a hinge 7.
- the hinge 7 is for example located between one end of the flange 16 (second part) and a lower zone of the first part 15.
- the axis of rotation of the joint is substantially parallel to the vertical direction D of the cap.
- the movement of the second part 16 relative to the first part is carried out in a direction perpendicular to the neck of the bottle 4. That is to say that by first positioning the first part on the neck of the bottle 4 (for example laterally in a direction perpendicular to the axis of the cap 1), the operator can then easily move the second portion 16 in the direction of tightening the neck of the bottle 4 (rotation R).
- FIG. 3 shows an alternative embodiment in which the cap has two parts 5, 6 forming half-hats. That is to say that the two parts 5, 6 are enveloping and substantially symmetrical (in the manner of half-shells). As previously, the two parts 5, 6 are linked by a hinge 7 whose axis of rotation is parallel to the vertical axis D (so-called elevation axis) of the hat 1.
- the two parts may comprise members adapted to urge or strengthen the maintenance of the two parts 5, 6 in their assembly position.
- the two parts 5, 6 may comprise magnets, ferromagnetic inserts or similar conjugates intended to come face to face in the assembly position.
- the cap 1 comprises two parts 5, 6 of substantially symmetrical general shapes (or two semi- wraparound shell-shaped shells) articulated to one another at their upper parts. More precisely, the two parts 5, 6 are connected at the level of two distinct joints 7 located respectively at two ends of the cap 1. The axes of rotation of the two joints 7 are merged. As shown in Figure 4, for its mounting on a bottle, the two parts 5, 6 of the cap 1 can be moved away in the manner of a clamp (rotation R) to allow mounting from the top around the neck 3 of the bottle around a tap 2 (translation T).
- the articulated connection 7 allows a positioning and a natural maintenance of the two parts 5, 6 in the assembly position (the position of the articulation axes 7 above the centers of gravity of the parts 5, 6 naturally tends to close the two parts 5, 6 in the assembly position (in particular when the cap 1 is held in the upper part, for example at a knob 11).
- the two parts 5, 6 may comprise members adapted to urge or strengthen the maintenance of the two parts 5, 6 in their assembly position.
- the two parts 5, 6 may comprise elastic holding systems such as clips 9 or the like conjugate intended to cooperate in the assembly position.
- the parts forming the cap 1 may be made of plastic and / or metal and / or any other suitable material or mixture.
- the cap 1 may have more than two parts mechanically linked by at least one linking system allowing limited relative movement.
- the cap can use for its attachment a ring forming a mounting interface intended to be interposed between the neck of the bottle and the parts forming the cowling.
- the ring may have an opening or cut on its circumference provided for its establishment or its withdrawal relative to the bottle (so as to form an open ring). The opening of the ring can thus form, during an introduction or withdrawal of the ring, a passage for a portion or section of a bottle or a valve 2 mounted on the bottle.
