Definitions

  • the present invention relates to a container for pressurized gases, and more specifically to a vessel or container meant to contain and transport gases under high or low pressure.
  • the object of the invention is to provide the market of the sector with a container for pressurized gases that can be transported in conventional pallets, allowing a fully compact packaging on the pallet and preventing the displacement of the containers with respect to each other.
  • a further object of the invention is to provide a container that is considerably lighter than conventional containers used for the same purpose.
  • Containers or vessels currently used to transport pressurized gases have a series of drawbacks and disadvantages, among which are the following:
  • Japanese patent application JP2011208720 A describes a pressure vessel satisfying both of mounting stability and portability, said vessel comprising at least a container body for storing LPG, a base, a mouthpiece and an outer case made of synthetic resin material or the like.
  • the container for pressurized gases disclosed has been conceived to solve the aforementioned drawbacks and provide additional advantages and features that will be described in the present description.
  • the container of the invention is characterized in that it consists of a metal inner sleeve consisting of a hollow cylinder with a small thickness, made of a light alloy (such as an aluminium alloy) with the ends thereof finished by a planishing process with a geodesic shape, on one of which ends is provided an opening for fitting the corresponding valve.
  • This inner sleeve in addition to enclosing the gas within it, can be considered to define a support for a casing made of a composite material of strands of carbon fiber, glass fiber or the like and a bi-component epoxy or vinyl-ester resin based on resin proper and a catalyst that acts as a hardener of the mixture after applying heat.
  • the process consists in the following:
  • the fiber strands, which are electronically stressed, are passed through a bath in which the two components of the resin have been mixed, such that they are impregnated, and then wound about the metal sleeve at previously calculated directions and angles until there are enough layers to withstand the internal pressure, thereby forming the composite casing.
  • the composite and inner sleeve assembly is introduced in an oven where two processes take place simultaneously: on one hand the resin is cured, with the difference that the time and temperature conditions employed are substantially greater than those necessary for this purpose in order to attain the artificial curing conditions for the metal of the inner sleeve, thereby allowing to recover or even improve the mechanical properties thereof which were altered during the planishing process used to shape the ends, without this representing any drawback for the correct curing of the resin.
  • the assembly formed by the matured metal sleeve and the cured composite casing is complemented by a protective sheath of a thermoplastic material with a certain elastomer grade, comprising segments with a circular section alternating with segments with a hexagonal section such that the segments with a circular section contact and hold on their inside the container formed by the inner sleeve and the composite casing, while externally the circular segment or segments provide a housing for a universal strap that bundles a set of containers on a pallet.
  • hexagonal sections of the sheath internally these sections do not touch the composite, allowing a deformation after a fall or an external load, that is, absorbing said load such that it is not transmitted to the composite damaging the same.
  • the upper end of the aforementioned protective sheath includes two tabs that engage a metal ring fitted on the end of the valve of the inner sleeve, thereby preventing the rotation of one element with respect to the other, while the bottom end of said protective sheath of a thermoplastic material includes a cross-shaped groove that prevents the rotation of this part with respect to a lower metal body that completes the protective sheath itself.
  • the body of the sheath is obtained by extrusion-blowing technology, the mold incorporating mobile blades that make a slit during the blowing process such that these parts are obtained as two separate pieces, the aforementioned top part made from alternating segments with a circular section and segments with a hexagonal section, and another part with a circular section that is assembled on the top part after inserting the container by means of complementary inner and outer clips that lock and attach to one other, such that the clips are arranged in correspondence with each of the edges of the hexagonal section of the sheath itself.
  • the container constructed in this way is complemented by the corresponding stand for support on the floor, this stand having a cup shape and being made of metal, preferably aluminium, obtained by cold stamping, the main function of which is to protect the assembly from any external loads resulting from transport.
  • Said stand includes in the base thereof and internally a cross-shaped groove complementary to that provided on the bottom part of the sheath body, the two grooves engaging one another to prevent the rotation of one body about the other, said stand being secured by rivets in correspondence with each of the clips of the upper body, these rivets crossing both parts of the plastic such that, in addition to holding the stand, they prevent the clips from being released accidentally.
  • the corresponding valve guard provided to protect the valve from the protector described above has a hexagonal cross section throughout its entire length, and is preferably made of a plastic material as it is cheaper than metal, using less material as the thickness thereof can be reduced since the hexagonal outline configuration provides a greater strength to the valve guard itself.
  • the container includes a passive RFID tag for radio frequency identification, allowing to view, control and record in real time the traceability of the containers both during the manufacturing process thereof and subsequently during their use in filling, restamping and other lines.
  • RFID technology in this container provides safety at the time of filling and allows an unmanned checking of up-to-date periodic inspections or that the working pressure conforms to the filling set-point, thereby reducing administrative and container control tasks and allowing automation of hitherto manual processes such as issuing delivery notes, work and/or production reports, etc., while making it possible to handle a much greater volume of containers in a work shift compared to the current barcode system.
  • the container of the invention labelled in general by the numeral (1) in figure 1 , has a body with hexagonal polygonal sections (2), ending at the top at a valve guard (4), while the numeral (5) references the valve itself.
  • the container (1) consists in an inner sleeve (6) made of metal and with a cylindrical shape, with ends having a geodesic shape (7) and one end provided with an opening (8) by which gas is introduced through the corresponding commercially-available valve (5).
  • This sleeve (6) incorporates in correspondence with the opening thereof a ring (9) of the same metal, inserted by heating such that it expands, the ring (9) having a pair of grooves (10) the function of which will be described below, and is also provided with an outer thread (11) for screwing on the valve guard. (4).
  • FIG. 5 shows the upper part of said sheath (13) with the ring (9) mounted on the corresponding inner sleeve, the ring of which already incorporates the aforementioned grooves (10) in which are inserted the corresponding tabs (20) to prevent the two parts from rotating about each other.
  • the protective sheath (13-13') is complemented by a stand (21) defined in the bottom body (13'), with a cup-shaped configuration and a cross-shaped groove (22) at the base thereof that complements the groove (19) and locks one in the other to prevent the rotation of the elements about each other, and it is also secured by rivets (23) that pass through orifices (24) provided on the lateral surfaces of the upper (13) and lower (13') parts of the sheath.
  • valve guard (25) shown in figure 11 has the special characteristic of having a hexagonal perimeter, defining internal edges (26) that stiffen said body, which consequently can be made of lighter materials than those normally used, reducing the weight and cost thereof.
  • Said valve guard (25) comprises corresponding openings (27) for actuating the corresponding valve (5) and a thread (28) for assembly thereof on the upper part of the described container.
