Definitions

  • This invention relates to a gas capsule for storing small volumes of gas under pressure.
  • a capsule is referred to herein as a “compressed gas capsule”.
  • the compressed gas capsules according to the present invention have a water capacity of typically less than 21 cm 3 .
  • Compressed gas capsules are well known. They are conventionally provided with a non-renewable sealing means. On breaking the seal the contents of the capsule are rapidly delivered. Once the capsule has been used, it is thrown away.
  • GB-A-253 744 describes a gas delivery system including a metal capsule for gases or liquids under pressure which can be used to inflate a flexible container.
  • the capsule includes a hollow body with a neck extending therefrom and a stopper located in the neck in a fluid-tight manner.
  • the stopper has a stem extending outwardly from the neck.
  • the stem is formed with a passage in communication with the interior of the hollow body.
  • the stem has an external thread for connection to a handle forming part of the flexible container, so that when it is required to liberate the gas or liquid from the capsule the hollow body is moved laterally relative to the handle and the stem connected thereto such that the stem is ruptured thereby releasing the gas or liquid from the interior of the hollow body.
  • EP-A-757 202 discloses a compressed gas capsule having a hollow body with a neck extending therefrom.
  • a stopper is located in the neck in a fluid- tight manner.
  • the stopper has a stem including a frangible section.
  • the stem extends outwardly from the neck and is formed with a passage in communication with the interior of the hollow body.
  • Mechanical means are provided for rupturing the stem about the frangible section thereby allowing the escape of gas through the passage from the hollow body.
  • the stopper is typically laser welded within the hollow neck.
  • Such gas capsules are intended to be disposable. There are not able to be refilled.
  • a compressed gas capsule comprising a hollow bulb containing the compressed gas, the hollow bulb having a mouth engaging fluid-tight a valve which has a valve member normally biased into a valve-closing position, but which, when it is desired to deliver gas, is able to be urged by the application of a sufficient external pressure into a position in which the valve is open, wherein the bulb has at its head a mouth which is defined by an elongate nozzle integral with the head of the bulb, the outer end of the valve being located wholly within the elongate nozzle.
  • the valve can be closed at any time a user desires by releasing the external pressure. When this is done the valve member returns to its normal valve-closing position.
  • a compressed gas capsule according to the invention is able to be refilled with compressed gas.
  • the bulb is preferably formed as a one-piece article with its head integral with its base.
  • the valve may be formed as a two-piece article with its head bonded to the rest of its body, for example, by laser welding.
  • a one-piece construction is advantageous in that it avoids the need for a bonding or joining operation to join the head to the rest of the body of the bulb.
  • the bulb is preferably formed as a one-piece article by deep drawing but other forming methods can be used instead.
  • the bulb is preferably formed of stainless steel. It is, however, possible to form the bulb of aluminium, an alloy based on aluminium, or mild steel.
  • Stainless steel offers the advantage of being less prone to corrosion than either mild steel or aluminium. Stainless steel bulbs are thus easier to clean during manufacture and filling and have greater ultimate strength than those of either mild steel or aluminium.
  • the valve preferably comprises a sleeve, the inner end of which forms a valve seat; a valve member adapted to make a fluid-tight engagement with the valve seat when the valve is in its closed position; a spindle integral with or carrying the valve member, the spindle having a head against which the external valve-opening pressure can be exerted, and a compression spring which acts on the spindle in a valve-closing direction.
  • the external pressure thus needs to overcome the bias of the compression spring in order for the valve to be opened.
  • the elongate nozzle also serves to protect the valve from damage if the gas capsule is dropped.
  • the elongate nozzle preferably has an external screw thread engagable with a valve opening member which has a complementary screw thread, a body with a gas passage therethrough and a spigot which is adapted to bear against the spindle of the valve when the valve-opening member is engaged with the external screw threads of the elongate nozzle.
  • the bulb preferably has a domed base. Such a configuration enhances the strength of the bulb.
  • the bulb is able to store gas at a pressure up to 100 bar or higher.
  • the upper pressure limit is typically determined by the maximum pressure to which the valve may safely be subjected. This maximum may for example be in the order of 300 bar. Nevertheless, the gas is preferably stored at a pressure in the range of 25 - 100 bar.
  • the bulb may be provided with a stand which engages or is bonded to the base of the bulb.
  • Any permanent gas or mixture of permanent gases may be stored in a pressurised gas capsule according to the invention.
  • One example is helium.
  • Figure 1 is a schematic sectional elevation of a first embodiment of a compressed gas capsule according to the invention, the gas capsule comprising a one-piece bulb;
  • Figure 2 is a schematic sectional elevation of another embodiment of a compressed gas capsule according to the invention, the gas capsule comprising a two piece bulb;
  • Figure 3 shows a valve opening member for use with a gas capsule of the kind shown in Figure 1.
  • the drawings are not to scale.
  • a compressed gas capsule 2 comprises a hollow cylindrical bulb 4 which is symmetrical about it longitudinal axis and which has a head 6 and a domed base 7.
  • the bulb 4 has at its head 6 an elongate nozzle 8 which is integral with the head 6 and defines mouth 10 of the bulb 4.
  • the mouth 10 is symmetrical about the longitudinal axis of the bulb 4.
  • the bulb 2 and the nozzle 8 form a one piece article.
  • the bulb is able to store gas at high pressure, for example a pressure of between 25 and 100 bar. Higher storage pressures are also possible.
  • the bulb 4 preferably has a water capacity in the range of 10cm 3 - 20cm 3 . It is typically made of stainless steel by a deep drawing process.
  • the interior surface of the mouth 10 of the bulb 4 makes a screw-threaded engagement with complementary threads of a sleeve 14 which forms the body of a valve 12.
  • the sleeve 14 tapers from its outer to its inner end.
  • a valve seat 16 is formed at the inner end of the sleeve 14.
  • the valve 12 has a valve member 18 which is integral with a spindle 20 received within the sleeve 14.
  • the spindle 20 is coaxial with the bulb 4.
  • the valve 12 additionally includes a compression spring 22. One end of the compression spring 22 engages a seat 24 which is integral with the sleeve 14.
  • the other end of the compression spring 22 bears against a collar 26 which is integral with the spindle 20.
  • the compression spring 22 exerts a spring pressure against the collar 26 in a valve-closing direction.
  • the spindle 20 extends beyond the sleeve 14 and ends in a head 28.
  • Application of a sufficient external pressure to the head 28 causes the valve member 18 to be displaced against the bias of the compression spring 22 out of valve-closing engagement with the seat 16.
  • an annular seal 30 of suitable plastics material for example PTFE
  • the outer end of the nozzle 8 has on its external surface a screw thread 32. As shown in Figure 3, the thread 32 is adapted to engage a complementary screw thread 36 on the body 38 of a valve-opening member 34. A spigot 40 extends from the body 38. The body 38 also has a passage 42 formed therethrough. The passage may be of defined diameter so as to give a defined flow rate of gas therethrough.
  • the valve-opening member 38 is screwed onto the outer end of the nozzle 8 causing the spigot 40 to engage the head 28 of the valve spindle 20.
  • the arrangement shown in Figure 3 may also be used when it is desired to fill or refill an empty gas capsule 2.
  • the connector 44 is connected to a source of compressed gas (not shown).
  • the acts of engaging the valve-opening member 34 with the nozzle 8 and tightening the screw threads causes the valve 12 to open and compressed gas to flow from the source of compressed gas through the nozzle 8 into the bulb 4.
  • the valve opening member 34 may be unscrewed allowing the compression spring 22 to urge the valve member 18 back into valve-closing engagement with the valve seat 16.
  • the compressed gas capsule shown in Figure 1 may be used to supply gas for a number of different purposes, typically, either for the purpose of inflating means such as a life raft or life jacket or for propulsion purposes, for example, for propelling a pharmaceutical powder through the skin of a patient.
  • Other uses for the compressed gas capsule shown in Figure 1 include the delivery of gas to a reactor.
  • the bulb 4 may alternatively have a two-piece configuration, comprising a body 200 laser-welded or otherwise bonded to a head 202.
  • the gas capsule shown in Figure 2 is essentially identical to that shown in Figure 1.
