Definitions

  • the present invention relates to containers for containing or storing a liquid gas.
  • liquid gas any body having in its storage conditions (in particular pressure, temperature) two phases, namely liquid and gas, normally separated by an interface.
  • It may be a liquefied gas, that is to say a body for which the liquid phase is in equilibrium with its vapor phase, the gas pressure inside the container then being equal to the pressure vapor from said body; in the first rank of liquefied gases are liquefied petroleum gases (or LPG), for example butane, by reference to which the present invention will be explained.
  • LPG liquefied petroleum gases
  • It may also be a dissolved gas, that is to say a body whose gaseous phase is in equilibrium with a phase dissolved in an appropriate solvent, the latter constituting the liquid phase which has been discussed. previously.
  • LPG liquefied petroleum gases
  • the liquid gas contained in the container may or may not be under pressure, the internal pressure within the container being less, greater than or equal to the ambient or external pressure, for example atmospheric.
  • the temperature of the liquid gas may or may not be lower than or equal to the ambient temperature; the containers according to the invention can be cryogenic storage, that is to say intended to store liquefied gases at very low temperature, for example liquid nitrogen.
  • the present invention is concerned with containers as defined above, capable of delivering in the gas phase, and only in this form, the liquid gas which they contain. Indeed, in most uses of the gas phase, the untimely withdrawal of the liquid phase, under the effect of various causes, for example an inadequate position of the container, leads to various drawbacks, even dangers. Thus, if we refer to a soldering lamp with gas burner, powered by a commercial butane cartridge, the lamp must be at the start held vertically, so that we are sure to take the gas only in gaseous form, that is to say in the gaseous sky of the cartridge. Any agitation, for example tilting of the cartridge, leads to a collection of drops of liquid phase, and to a direct combustion of the latter in the burner. As it is designed to work in the gas phase, the introduction of the liquid phase immediately causes the appearance of long soft flames, yellow in color, due to combustion without secondary air; for certain devices, for example domestic type, the appearance of such flames can be dangerous.
  • each of the solutions envisaged above leads, for a container of a given capacity, to store a limited quantity of the liquid gas, in any case an amount well below the available capacity of the container.
  • valve cartridge whose diameter and height are 40 mm and 125 mm respectively, and therefore a container whose height exceeds the width or diameter.
  • the minimum useful volume taking into account the size of the valve, is 135 cm3.
  • part of this useful volume must be allocated to the gas phase (at least 5% at 50 ° C), and consequently the maximum volume that can be assigned to the liquid phase is 124.5 cm 3 , which, taking into account the density of commercial butane at 50 ° C, or 0.513 kg / I, represents a butane charge at most equal to 63.84 g, hereinafter called m o .
  • the same cartridge applies the solution according to American patent 2 465 643, that is to say incorporates a feed tube to halfway up this container.
  • the maximum volume that can be allocated to the liquid phase is 67.5 cm 3 , not taking into account the supply tube, which, taking into account the density of commercial butane at 50 ° C., represents a butane charge at most equal to 34.691, ie 54% of mo.
  • the minimum available useful volume is 121.4 cm 3 .
  • the maximum volume that can be allocated to the liquid phase of commercial butane is 115.3 cm3, which corresponds to 50 ° C at a charge of butane at most equal to 59.6 g , hereinafter called m i , and equal to approximately 93% of mo.
  • the object of the present invention for a container with absorbent material is to increase the load of liquid phase which can be absorbed, for a given geometry and dimensions of the container.
  • a gas sampling device only in phase gas is disposed in the sampling zone, extends at least partially inside the body, and comprises an inlet and an outlet, and on the other hand the free end of the supply tube is arranged, without contact with the buffer, between the sampling device and the bottom of the body, and the other end of the same tube communicates in a sealed manner with the inlet of the sampling device.
  • free end is meant the part of the supply tube comprising one or more orifices for withdrawing liquid gas in gaseous form. According to the invention, this free end is arranged at a distance from the wall of the recess of the tampon, for example in the center of the latter, to avoid any contact of the withdrawal orifice (or of its border) directly with the absorbent pad.
  • the inlet (in the direction of flow of the gas sampled) of the chosen sampling device ensuring communication between the interior and the exterior of the container, communicates in leaktight manner with the end of the supply tube opposite the withdrawal orifice; tightness meaning that the junction between the tube and the sampling device is tight vis-à-vis the liquid phase of the gas, possibly present is tight vis-à-vis the liquid phase of the gas, possibly present inside of the container, freely, that is to say outside of the absorbent material.
  • the gas cartridge 1 illustrated in fig. 1 comprises a body 2 produced in one piece by spinning or extruding an aluminum ingot as is well known.
  • the body 2 has a bottom concave bottom 2a and an upper opening 2b bordered by a peripheral bead 2c. After filling the opening 2b is closed by a cup 3 whose periphery 3a is crimped relative to the bead 2c of the body 2, a seal 4 being disposed between these two elements so as to ensure a perfect seal.
  • the center of the cup 3 has a hollow boss 2Lb open downwards which retains a valve body 5 by centripetal constriction below a head 5a of said valve.
  • This is associated in a sealed manner with a dip tube 6 disposed in a perforated chimney 7 extending in the axis of the body 2, and which is intended for the supply of gas.
  • a filter 8 is placed between the valve 5 and the dip tube 6 so that the gas taken from the body 1 escapes, when desired, out of the valve 5 with only an extremely small number of suspended particles in suspension. impurities.
  • the perforated chimney 7 which is made of a suitable plastic material surrounds with clearance the dip tube 6 and constitutes a separation between an annular pad of absorbent material designated under the general reference 9, and said dip tube.
  • this pad 9 has an elongated central recess 9a so that the perforated chimney 7 forms an internal facing of the recess of this pad. It is observed that the recess 9a extends practically over the entire height of the body 2.
  • the perforated chimney 7 has an upper part 7a surrounding with play the corresponding part of the dip tube 6 and which ends in a collar 7h bearing on the top of the pad 9 which is itself at a certain distance below the cup 3 .
  • a tamper-evident cap 10 shown in broken lines comprises a central chimney 10a which cooperates with the interior of the peripheral part 3a of the cup 3 and an outer skirt 10 - b comprising in the known manner a lower annular projection 10c coming s' engage elastically under the bead 2c of the body 2.
  • the bottom of the skirt 10b is associated by means of a weakening line with a strip tearable guarantee 11 ensuring the authenticity of the contents of the cartridge 1, as long as it is not destroyed.
  • the outlet of the supply plunger tube in the recess 9a is located at the median level of said recess.
  • the supply tube consists of a one-piece hollow piece, closed at one end 6c and comprising two external annular ribs 6d and 6e. These ribs, similar to two transverse partitions, and more precisely perpendicular to the axis of the cartridge, delimit with the wall of the recess 9, and more precisely with the perforated chimney 7, a withdrawal cage 22, in which is included the free end 6a of the tube.
  • the two ribs or partitions 6d and 6g form spacers between the chimney 7 and the tube 6 and thus preserve the free end of the latter from any contact with the pad of absorbent material 9.
  • the partition 6d provided at the free end 6a closes the supply tube and for withdrawal, the tube comprises two withdrawal orifices, or slots 6f extending between the two partitions 6d and 6e.
  • the withdrawal opening (s) are protected in their immediate environment, against any particle or other dispersed form of absorbent material, interposed between the free end of the supply tube of on the one hand, and the absorbent pad on the other. Such interposition would establish a "bridge” between the tube and the absorbent material, like a wick carrying unwanted liquid phase to the tube.
  • m 1 is the theoretical maximum butane load evaluated as indicated in the preamble to this description, taking into account the volume of the recess.
  • this sheet is passed through a defibrator 15 from which a centrifugal fan 16 sends the separated fibers into a hopper 17 in which the said fibers are separated from the air.
  • a centrifugal fan 16 sends the separated fibers into a hopper 17 in which the said fibers are separated from the air.
  • Another fan 18 draws air into the defibrator 15 and into the hopper 17 and rejects it outside after it has passed through a filtration device 19.
  • the fibers arranged in the hopper 17 fall into a metering chimney 20 supplying an archimedean screw 21.
  • the latter by rotation compresses the fibers in the bodies 2 placed axially successively at the outlet of this screw. It is expected to have a central mandrel not shown in each body 2 so that the fibers are arranged in a ring around this mandrel which allows the formation of the recess 9a and the establishment of the perforated chimney 7 in this recess.
