The invention relates to an assembly including a tap for controlling fluid under pressure and a protective cap mounted around said tap, the tap including at least one handling member that includes a lever pivotably connected to the body of the tap and manually actuatable by an operator between at least a first rest position adjacent to the body of the tap and a second active position shifted by a nonzero angle relative to the body of the tap, the cap defining an inner protective space for the tap and being provided with at least one first side opening that enables movement of the lever between the first and second positions, the lever in the second position thereof intercepting the plane of the first opening and optionally projecting beyond the space of the cap, and characterized in that, in the mounted position for the use thereof, the cap is turning, that is, freely movable in rotation relative to the body of the tap around an axis, and in that the portion of the cap defining the first opening has contact edges capable of coming into contact with the lever when the latter intercepts the plane of the first opening and in that the cap is set into rotation relative to the tap, the contact edges being oriented according to predetermined angles to exert force on the lever urging the latter towards the first position thereof.

1. An assembly including a tap for controlling fluid under pressure and a protective cap mounted around said tap, the tap including a body having a vertical axis and an internal fluid distribution circuit between an inlet adapted to be connected to a fluid source such as a bottle and a fluid outlet,
1. An assembly including a tap for controlling fluid under pressure and a protective cap mounted around said tap, the tap including a body having a vertical axis and an internal fluid distribution circuit between an inlet adapted to be connected to a fluid source such as a bottle and a fluid outlet, at least one element for controlling the flow of fluid is situated in the internal circuit and at least one handling member includes a lever pivotably connected to the body of the tap and manually operable by an operator between at least a rest position adjacent to the body of the tap and an active position shifted by a non-zero angle relative to the body of the tap, the cap defines an inner protective space for the tap and is provided with at least one first lateral opening that enables movement of the lever between the rest and active positions, when in the active position the lever intersects the plane of the first opening and optionally projects beyond the volume of the cap, wherein: in the mounted position for the use therefore, the cap freely rotatably mobile relative to the body of the tap about the vertical axis,the portion of the cap defining the first opening has contact edges adapted to come into contact with the lever when the latter intersects the plane of the first opening and the cap is set into rotation relative to the tap, andthe contact edges are oriented according to predetermined angles to exert a force on the lever urging the lever towards the rest position. 2. The assembly of claim 1, wherein at least part of the contact edges have an orientation inclined relative to the vertical axis. 3. The assembly of claim 1, wherein at least part of the contact edges are curved or inclined toward the interior of the first opening. 4. The assembly of claim 1, wherein, in a vertical plane, the contact edges have a portion inclined at an angle of 14-30 degrees. 5. The assembly of claim 4, wherein, in a vertical plane, the contact edges have a portion inclined at an angle of 17-25 degrees. 6. The assembly of claim 1, wherein the first opening is delimited on its circumference by substantially vertical lateral members, a substantially horizontal upper member and a substantially horizontal lower member, the contact edges being situated on the lateral members and/or on the upper member. 7. The assembly of claim 1, wherein the cap includes at least one second lateral opening having dimensions preventing complete movement of the lever between the rest and active positions and preventing mounting of a pressure regulator via the at least one second opening. 8. The assembly of claim 1, wherein an upper part of the cap is open. 9. The assembly of claim 1, wherein the cap includes a fourth lateral opening provided for access to the tap. 10. The assembly of claim 9, wherein the fourth lateral opening provides access to a fluid outlet connector of the tap and/or a pressure indicator. 11. The assembly of claim 1, wherein the cap is made of a charged plastic material selected from the group consisting of polyamide, polyester, and polybutylene tetraphthalate. 12. A pressurized fluid bottle having an orifice, wherein: the assembly of claim 1 is mounted at the orifice,the tap is mounted on the bottle such that the tap cannot rotate thereon, andthe cap is mounted to rotate freely relative to the vertical axis of the bottle and the tap. 13. The pressurized fluid bottle of claim 12, wherein said bottle contains nitrogen.
