Definitions

• the present invention relates to a protective cap for pressurized fluid bottle tap and a bottle provided with such a cap.
• the invention relates more particularly to a protective cap for a pressurized fluid bottle valve comprising a body whose first end is intended to be mounted on a bottle and whose other end comprises a manual gripping member, the gripping member being rotatably mounted relative to the remainder of the body of the cap about an axis of rotation, to allow the rolling of a bottle provided with such a cap by manually holding the bottle vertically by the gripping member.
• One solution is to provide casters at the base of the bottles. Another solution is to use trolleys with wheels.
• Another solution adopted by some users is to roll the bottles by their base. That is to say that the operator holds the bottle with a first hand from above (where we usually find a protective hat and sometimes a knob) and rolls the bottle by pushing with the foot or with his other hand.
• faucet elements protected by the cap are not easily accessible once the cap is in place.
• the protective cap must be removed to access some of the elements it protects, for example a vertical filling port located under an upper knob 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 cap according to the invention is essentially characterized in that the cap comprises a selectively movable locking member between a first position in which the locking member provides a mechanical locking of the translation of the gripping member along the axis of rotation relative to the body of the cap to prevent the physical separation of the gripping member relative to the body of the cap and a second position in which the blocking member does not lock the translation of the gripping member along the axis of rotation relative to the body of the cap, to allow the physical separation of the gripping member relative to the body of the cap.
• embodiments of the invention may include one or more of the following features:
• the locking member is urged by default to its first position by a return member disposed in the gripping member and / or in the body of the cap,
• the locking member is movable from the first position to the second position by mechanical and / or magnetic actuation
• the locking member comprises one or balls disposed in respective housings formed in the body of the gripping member, the ball or balls cooperating selectively in abutment with a portion of the body of the cap,
• the ball or balls form a rolling mechanism between the member and the body of the cap
• the locking blocking member is constrained in its first position by an intermediate pusher
• the intermediate pusher is slidably mounted in the body of the locking member
• the intermediate pusher comprises a body made of a material that can be displaced in the body of the locking member under the action of a determined magnetic field
• the gripping member is rotatably mounted in a hole of the cap so that when the gripping member is physically separated from the cap, the orifice forms an additional access to the protective volume defined by the cap.
• the invention also relates to a bottle of pressurized fluid comprising a neck on which is mounted a protective cap according to any one of the above characteristics or below.
• the invention may also relate to any alternative device or method comprising any combination of the above or below features.
• FIG. 1 represents a side view of a pressurized fluid bottle provided with a rotating knob cap according to an exemplary embodiment of the invention
• FIG. 2 represents a perspective view of a detail of a protective cap with the rotating knob removed from the cap
• FIG. 3 represents a view in vertical section, diagrammatic and partial, of the detail of FIG. 1 in which the rotating knob is secured to the upper end of the cap,
• FIG. 4 and 5 show sectional views similar to that of Figure 2, respectively illustrating two successive steps of selective disconnection of the knob relative to the cap.
• the bottle 6 of pressurized fluid shown in Figure 1 comprises, mounted on its upper end, a cap 5 for protecting a valve.
• valve of the bottle 6 is not shown.
• the valve can be screwed into the tapped opening of the bottle 6.
• the valve is housed at least partially in the cap 5.
• the example shown hat 5 has the general shape of an arch. Of course, the invention can be applied to any other hat geometry.
• the cap 5 comprises a body whose upper end comprises a manual gripping member comprising a knob 1 rotating.
• the knob 1 has for example the general shape of a mushroom. Of course, any other form and can be considered.
• the knob 1 is rotatably mounted relative to the rest of the body of the cap 5 to allow the rolling of the bottle 6 provided with such a cap 5 (in mounted position, the cap 5 is integral in rotation with the bottle 6).
• the knob 1 can be selectively physically separated from the body of the cap 5.
• the knob 1 is rotatably mounted on the cap 5 in a hole 25 of the cap 5.
• this orifice 25 is through, that is to say that, when the gripping member 1 is physically separated from the cap 5, the orifice 25 forms an additional access to the protective volume delimited by the cap, for example towards a valve element housed in the cap and in particular a filling port.
• the gripping member 1 is rotatably mounted relative to the remainder of the body of the cap 5 about an axis A of rotation coinciding with a central axis extending between the base and the upper part of the cap 5.
• the cap 5 comprises a locking member 4 selectively movable between a first position in which it provides a mechanical locking of the translation of the knob 1 along the axis A of rotation and a second position in which the locking member 4 does not lock the translation of the knob 1 along the axis A of rotation relative to the body of the cap 5.
• the knob 1 In the first position of the locking member 4, the knob 1 can rotate relative to the body of the cap 5 but is integral with it. In the second position of the locking member 4, the knob 1 can be separated manually from the body of the cap 5.
• the selectively locking member 4 of the knob 1 is urged by default to its first position by a return member 3 such as a spring disposed in the knob 1.
• the locking member 4 may comprise balls arranged around the axis A of rotation in respective housings formed in the body of the knob 1. Depending on the radial position of the balls relative to the axis A of rotation, the balls selectively cooperate in abutment or not with a portion 15 of the body of the cap 5.
• the balls 4 come for example to lock against a border 15 of the orifice 25 of the body of the hat receiving the pommel 1.
• the balls 4 are for example forced towards a first external position by the spring 3, via intermediate pusher 2 which slides in the body of the knob 1.
• the knob 1 In the normal situation, the knob 1 is in the locked position on the body of the cap 5.
• the spring 3 pushes the pusher 2 against the wall of the knob 1, thus trapping the balls 4 between this wall of the body knob 1 and the body of the cap 5. This keeps the set locked.
• the ball or balls 4 can form, for example, a rolling mechanism between the knob 1 and the body of the cap 5.
• the balls 4 are for example movable from the first position to the second position by mechanical and / or magnetic and / or hydraulic and / or pneumatic actuation, for example via the pusher 2.
• a specific tool is necessary to ensure the unlocking of the knob 1 relative to the body of the cap 5.
• an electromagnet 7 lifts the pusher 2 to release the balls 4 held between the pusher 2 and the body of the cap 5 (see Figure 4).
• the intermediate pusher 2 comprises a body consisting of a material that can be moved under the action of a particular magnetic field, for example metallic.
• the assembly can then be removed, thus freeing access to the organs below (see Figure 5).
• the locking of the knob on the body of the cap 5 can be unlocked via a mechanical key that acts directly on a stop.
• knob 1 may be of any other suitable form, for example an annular handle.
