Definitions

  • the present invention relates to the field of gas containers, in particular that of gas cylinders, and more precisely the rollovers protection intended to equip such gas containers.
  • the protection of cylinder valves is essential for Security. In the event of a fall, when transporting the bottles, the caps must provide sufficient protection for the valve so that it remains maneuverable after the bottle has been dropped.
  • the EN962 standard specifies the design, construction and testing of these caps.
  • caps are used for handling bottles and they also participate in their commercial image.
  • Open hats offer many advantages over closed hats. They allow, in fact, to access gas without having to be removed, both during packaging and when using the bottle.
  • the open hats of large bottles are mainly made of metal. Indeed, the weight of these 40 bottles at 100 kg, makes the mechanical strength requirements of the hat very high.
  • Plastic caps do not offer resistance sufficient, particularly with regard to the fixing thread on the flange of the bottle.
  • plastic hats have the advantage to be able to be produced more easily, that is to say by simple molding, and are also lighter than metal ones.
  • plastic caps have the advantage of not be sensitive to corrosion due to their composition, which is not the case of certain metal hats.
  • the solution provided by the present invention is a bi-material hat composed of a metal insert overmolded in a structure of cover in polymer material.
  • the present invention therefore relates to a protective cover open for fluid container, especially for gas bottle, compound a casing body of polymer material comprising a metal insert or in tapped metal alloy.
  • the invention also relates to a container for fluid, in particular a gas cylinder, equipped with a valve block or a valve / regulator assembly and bearing, in addition, a protective cover according to the invention.
  • the insert is made by molding an alloy metal and subsequent tapping of its internal wall.
  • Figure 1 shows schematically different possible forms of rollover open type protection, which is conventionally encountered in art prior. These are usually formed from a single structure in one metal alloy.
  • FIGS 2 and 3 represent two modes of production of cowlings 1 according to the invention.
  • the cowlings of Figures 2 and 3 each consist of a body 1 cowling provided, at its base 4, with a metal insert 2.
  • the insert 2 is made of a metal alloy molded, for example Zamac 5, and intended to ensure the connection between the bottle rim and polymer shape.
  • Its tapping dimensions are a function of the dimensions and tolerances of the flange of the bottle, as well as the shrinkage generated by the polymer form when the cap hardens (compression of the insert).
  • the insert 2 has 6 ribbed reinforcements. Recesses 7 also allow a good connection between insert 2 and the plastic, as well as a good flow at the time of molding.
  • Screw passages 11 are provided for fixing and blocking effective of the cap on the gas cylinder.
  • the polymer body 1 consists of impact-modified polyamide 6, for example Grilon TM .
  • the shape of the hat combined with the characteristics of this polymer, solves the technical stiffness / absorption problems mentioned above.
  • the body is surmounted by a knob 3 used for handling and may contain an electronic chip (not shown). Indeed, the plastic material of the cover makes the magnetic reading of the chip more easier and more efficient than in the case of a metal casing.
  • the hats are made as explained below.
  • the inserts are pre-molded and tapped.
  • an overmolding is carried out which consists in placing the insert on a insert holder around the core of the polymer mold.
  • the two fingerprints of the mold is closed, sealing is ensured between the cavities, the core and the insert itself.
  • the polymeric material is then injected and polymerized in the mold.
  • a protective cap according to the invention can be used for protect fragile organs, in particular valves, regulators and / or manometers, gas cylinders intended for any field of activity, in particularly in the field of welding, electronics, food and of health.
