Definitions

  • the present invention relates to a protective cap for a valve, a cap and a corresponding fluid pressure bottle.
  • the invention relates more particularly to a protective cap for a pressurized fluid bottle valve comprising a body whose one end is intended to be mounted on a bottle and whose other end comprises a manual grip.
  • 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 one hand from the top (where one usually finds a protective hat and sometimes a pommel) and rolls the bottle by pushing with the foot or with his other hand.
  • An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
  • the protective cap according to the invention is essentially characterized in that it comprises a cap removably attached to the pommel, in fixed position said cap being secured in translation of the knob but free in rotation on the latter.
  • Such a structure facilitates grip of the knob via a rotating cap.
  • this solution can be used easily on existing bottle caps with a non-rotating knob.
  • the invention also relates to a bottle of pressurized fluid comprising a cap according to any one of the above characteristics or below.
  • a cap for a pressurized fluid bottle cap comprising a generally hollow dome-shaped body whose base edge forms a continuous or discrete rim facing inwardly of the cap.
  • the invention may also relate to any alternative device or method comprising any combination of the above or below features.
  • the device illustrated in figure 1 comprises a bottle 3 of pressurized fluid provided with a protective cap 1 of a tap.
  • the bottle 3 is shown schematically and partially and the valve is not shown.
  • the protective cap 1 comprises a body of which a first lower end 2 is intended to be mounted on the bottle or a tap and a second upper end comprises a knob 4 for manual gripping.
  • the knob 4 is for example monobloc or fixed mounted (gluing, welding, riveting, screwing ...) on the body of the cap 1.
  • the cap 5 is removably attached to the knob 4.
  • the cap 5 is elastically deformable and snapped onto the end of the knob 4.
  • the cap 5 In the fixed position, the cap 5 is integral in translation of the knob 4 (longitudinally or laterally) but free to rotate on the latter.
  • the longitudinal direction is for example the direction of the axis of the knob 4 (parallel to the bottle longitudinal axis 3 when the cap 1 is mounted on the upper end of the bottle 3).
  • the knob 4 has the general shape of a mushroom that is to say a body 14 in the form of rod surmounted by a head 24 forming an outgrowth.
  • the head 24 has for example the general shape of a sphere portion.
  • any other geometry of knob 4 may be considered.
  • the cap 5 may have the general hollow shape of the shape of the head 24 of the knob 4, for example a dome.
  • the circular edge of the base of the cap 5 is provided with several elastic hooks 6 cooperating in resilient engagement with the head 24 of the knob 4.
  • the hooks 6 can be oriented towards the interior of the dome so as to hook at the base of the head 24 of the knob 4. For example, four to fifteen hooks 6 can be distributed around the circumference (circular) of the cap 5 .
  • the cap 5 is for example threaded so as to engage the head 24 of the knob 4 between the hooks 6 which deviate and then retract elastically when they reach the base of the head 24 of the knob 4.
  • This structure allows the cap 5 to rotate relative to the fixed pommel 4. An operator can thus grip the cap 5 to rotate the bottle 3 on itself.
  • the inner face of the cap and / or the outer face of the knob 4 may be shaped (shape or material) to facilitate this rotation (limited friction).
  • a layer of low friction material may be provided.
  • the inner face of the cap 5 may comprise ribs 7 which come into contact with the outer surface of the pommel 4 only according to point of support points and / or bearing lines.
  • the base of the cap 5 has the general shape of a U or an arc of a circle, that is to say that its border has a first end forming a lateral access opening.
  • the lower edge of the cap 5 has a flange 16 folded towards the inside of the cap to allow it to hook to the base of the head 24 of the knob 4.
  • the first end of the cap 5 is devoid of flange 6.
  • the cap 5 is introduced and threaded onto the head 24 of the knob 4 via its first end and in a direction transverse to the body 14 of the pommel.
  • the opening of the first end of the cap 5 has dimensions smaller than those of the head 24 of the knob 4 so as to require an elastic deformation of the cap 5 to allow the head 24 to enter the cap 5 ( removable installation by snap-fastening).
  • the cap 5 is held on the head 24 while being able to rotate around the head 24.
  • the cap 5 may comprise an opening, cut or notch 8 giving access to a portion of the head 24 of the knob 4 when the cap 5 is in a fixed position on the head 24.
  • This opening 8 may be provided at the first end 5 of the cap (at the opposite end of the closed end of the flange 16 closed cap 5.
  • This opening 8 may allow if necessary to put a finger (for example an inch) on the knob 4 or on the visible end of the head 24, for example to prevent the head 24 of the knob 4 from inadvertently out of the cap 5 and / or to control the relative rotation between these parts.
  • the cap 5 is snapped onto the end of the knob 4 with a functional clearance, for example a few millimeters.
  • the cap 5 is preferably made of plastic molded or injected.
  • the hat 1 has the general shape of a housing provided with lateral openings and where appropriate greater.
  • the invention can be applied to any other type of hat, for example in the form of a bow or other.
  • the invention makes it possible to easily and effectively equip bottle caps with a rotating knob.
