Definitions

  • the present invention relates to capsules for containing a volume of fluid at high pressure, that is, between 30 and 80 bar.
  • Sealed capsules are well known in circumstances where the force of the fluid under pressure is employed to dispense a substance such as discharging draught beer from a beer dispenser or expelling soda water from a soda siphon. They can also be used for liquid containers for soft drinks or beer under pressure.
  • a needle-less syringe which includes a metal capsule containing helium gas at high pressure which is used to force particles of a therapeutic agent through the skin of a patient in a substantially painless manner.
  • the capsule is detachable from the remainder of the syringe and once used, either a new charge of gas can be placed in the capsule or more favourably the capsule can be discarded and a new capsule charged with gas can be attached to the remainder of the syringe.
  • helium gas is a favoured fluid since it is very light which makes it suitable for use as a propellant for therapeutic agents in that when it impinges against the skin of a patient it will bounce off into the atmosphere and not pass through the skin of the patient.
  • helium because it is light, is difficult to contain since it will leak through the most minuscule fault in a container.
  • a method of filling a capsule having a hollow body portion from which extends a hollow neck portion with a fluid under pressure comprises the steps of:-
  • the fluid is helium at a pressure of at least 30 bar.
  • a capsule 1 comprises a hollow cylindrical body portion 2 made, for example, from aluminium or an aluminium alloy from which extends an elongate hollow neck portion 4 of smaller diameter than the body portion 2. Initially the neck portion 4 has an open free end 6.
  • a filling cap (not shown) is applied in a manner known per se to the free end 6 of the neck portion 4.
  • a vacuum is applied at the filling cap to evacuate the hollow cylinder body portion 2 after which the body portion 2 is filled with the fluid under pressure.
  • the neck portion 4 is crimped at a location spaced from said free end 6 (see Figure 2). This crimp is made sufficiently firm to avoid significant leakage of fluid from the body portion 2.
  • the filling cap is then removed from the free end 6 of the neck portion 4 to reveal said free end 6.
  • a second crimp is applied (see Figure 3) at or immediately adjacent said free end and at substantially the same time the free end 6 is laser welded to seal hermetically the end of the neck portion 4.
  • the purpose of the first crimp is to prevent fluid under pressure from reaching the second crimp and thus the free end 6 so that the laser weld can be made without gas permeation holes. Effectively, the two crimps define an interim chamber which prevents or inhibits fluid under pressure reaching the point where the free end 6 of the neck portion 4 is to be welded.
  • the crimps can be effected with either a circular swage type crimp or a simple flat crimp.
  • the fluid When the capsule is to be used in connection with a needleless syringe then the fluid will be helium at a pressure of at least 30 bar.
  • the capsule will contain a gas or liquid under pressure at substantially less than 30 bar.
