Definitions

  • This invention relates to a bombe device having a sealing plate unstoppering means comprising a pointed-end member adapted to the sealing plate of a bombe filled with a liquefied carbon dioxide or similar high-pressure fluid.
  • the bombe device of the present invention may be advantageously employed with a pouring out or dispensing device adapted to pour out beer, cola orthe like beverage stored in a vessel.
  • Typical dispensing devices for beverages such as beer or cola stored in a vessel allow high pressure gas such as carbon dioxide to be injected into the vessel, so that beverage is forced out from the vessel through a dispensing pipe under the pressure of the injected gas.
  • high pressure gas such as carbon dioxide
  • the high pressure gas is obtained from the bombe attached to the holder which itself is provided on the dispensing device.
  • the bombe filled with the compressed and liquefied carbon dioxide and hermetically closed, may be opened by unstoppering means provided in the holder.
  • the unstoppering means typically comprises an operating rod provided with a pointed-end member and reciprocally mounted within the holder. As the rod is reciprocated, the pointed-end member pierces the sealing plate provided on the bombe, thus forming a discharge orifice in the sealing plate.
  • the discharge orifice is closed and opened with the forward and reverse movement of the operating rod to inhibit and permit the discharge of gas, respectively.
  • the gas discharged through the orifice is conveyed into the cask through the injection pipe from the holder to act on the beverage stored therein and dispense it through the dispensing pipe.
  • the bombe being releasably mounted, is replaced by a new one when the high pressure gas is exhausted.
  • the pointed-end member of the operating rod must bore a new discharge orifice in the sealing plate every time the bombe is exchanged.
  • the present invention may also provide a bombe device wherein the sealing plate unstoppering means including the pointed-end member may be replaced simultaneously with the bombe replacement so that the sealing plate can be unstoppered by a fresh pointed-end member, free from deformation or breakage.
  • the present invention may provide a bombe device wherein the discharge orifice formed in the sealing plate of the bombe may be sealed by the guide member supporting the pointed-end member, thus effectively preventing leakage of the high pressure gas after unstoppering the sealing plate.
  • a bombe device comprising a bombe filled with pressurised fluid and having a sealing plate at one end; a tubular housing section surrounding the end of the bombe having the sealing plate; and a sealing plate unstoppering unit mounted within the housing section and having a pointed member for piercing the sealing plate, characterised in that an opening is provided at the end of the housing section far from the sealing plate, and at least one axially extending passage is formed in the unstoppering unit so as to provide fluid communication between the sealing plate and the opening.
  • the present invention may also make it possible reliably to prevent the leakage of the high pressure gas following unstoppering by providing the unstoppering means with means for closing the discharge orifice once formed in the sealing plate.
  • the bombe device of the present invention is includes a bombe 1 in the form of a cylinder in which a high pressure fluid is hermetically contained and which is accommodated within a bombe housing 2 adapted to be detachably fitted to, for example, the holder of a dispensing device.
  • the bombe 1 is filled with, for example, carbon dioxide in the compressed and liquefied state, and provided with a sealing end plate 3.
  • the bombe housing 2 comprises a front part 4 and a rear part 5 abutting and connected to each other.
  • These parts 4 and 5 are formed of synthetic resin and are profiled to conform to the outer peripheral shape of the bombe 1.
  • these parts 4 and 5 are connected together by screwing their threaded portions to each other with their inner wall surfaces intimately abutting and securing bombe 1.
  • the front part 4 of the bombe housing 2 has a cylindrical end section 6.
  • the cylindrical section 6 also provides a housing section 8 for accommodating an unstoppering unit 7 for unstoppering the sealing plate 3 provided on the bombe 1.
  • the unstoppering unit 7 comprises a guide member 9, slidably mounted as a valve body on the inner wall of the housing section 8, and a pointed-end member 10 disposed at the centre of the guide member 9 so that the point faces the sealing plate 3.
  • the guide member 9 is formed of a synthetic resin which resists deformation under the cooling effect of the carbon dioxide gas from the bombe 1 and exhibits a sealing effect to the discharge orifice 11 when the guide member 9 is pressed against the sealing plate 3.
  • the foremost part of the guide member 9 is tapered for forming a highly resilient portion 14 for abutment against the sealing plate 3.
  • the pointed-end member 10 is pressed into and held by the guide member 9 and has its pointed end projecting through the centre of the abutment portion 14 formed at the end face of the guide member 9 so as to confront the sealing plate 3.
  • the bottom end face 10a of the pointed-end member 10 is intended to be flush with the bottom end face 9a of the guide member 9. In use, the end face of the operating rod 15 of the dispensing device abuts these end faces 9a, 10a.
  • the pointed-end member 10 is positionally regulated by the end face of the operating rod 15 so that the bottom end face 10a will be flush with the bottom end face 9a of the guide member 9 and the distance the foremost part of the pointed-end member projects beyond the abutment portion 14 towards the sealing plate 3 will always be constant regardless of the force applied to the sealing plate 3.
  • a helical compression spring 16 is installed between the sealing plate 3 and the guide member 9.
  • the spring 16 urges the unstoppering unit 7 in the direction of the opening 12.
  • a shoulder 17 In the vicinity of the opening 12, there is formed a shoulder 17 for preventing the unstoppering unit 7 from disengaging from the bombe housing 2.
  • the bombe unit constructed in the above described manner is affixed to the dispensing unit by screwing the threaded mounting portion of the bombe housing 2 to the holder.
  • the foremost part of the operating rod 15 is gradually introduced through the opening 12 for pressing and actuating the unit 7 against the force of the spring 16. This causes the foremost end of the pointed-end member 10 to pierce the sealing plate 3 to form a discharge orifice 11 in it.
  • the rotation of the bombe housing 2 causes the operating rod 15 and the bombe to rotate with respect to each other.
  • the discharge orifice 11 With the discharge orifice 11 thus formed, the discharge orifice 11 remains closed by the pointed-end member 10 and the abutting portion 14 of the guide member 9, so that the carbon dioxide is prevented from discharging via the discharge orifice.
  • the foremost part of the guide member 9 forming the abutting portion 14 is slightly flexed by its own resiliency to take up the machining tolerance of the holder on the bombe unit to provide for positive sealing of the discharge orifice 11.
  • the bombe device together with the bombe housing 2 is replaced by a new one so that the gas will be obtained from the new bombe unit.
  • the sealing plate unstoppering means may be easily and positively replaced at the same time that the bombe 1 is replaced.
  • the unstoppering of the bombe 1 is always performed by the sharp pointed-end member 10 of the new unstoppering unit 7, so that the discharge orifice is always correct in shape, while the opening or closure of
  • the discharge orifice 11 is positively performed by the operation of the above described sealing plate unstoppering unit.
  • the bombe device since the bombe 1 is contained in and held by the bombe housing 2, the bombe device can be assembled easily. Since the bombe housing 2 can be fabricated from high workability material, such as synthetic resin, manufacture of the bombe unit is facilitated.
  • the bombe housing 2 since the outer surface of the bombe 1 is covered by the bombe housing 2, it is also possible to prevent water droplets from adhering to the outer surface of the bombe 1 as it is cooled by the discharged carbonic acid gas.
  • the bombe housing 2 is provided to cover the bombe 1 in its entirety.
  • the bombe device may comprise a bombe 1 and a mounting member 18 attached to the foremost part of the bombe 1, as shown in Fig. 6..
  • the mounting member 18 is in the form of a cylinder formed e.g. of metal.
  • the foremost part of the bombe 1 has a press fit into the mounting member so as to be affixed thereto as by riveting or welding.
  • the mounting member 18 On the outer periphery of the mounting member 18, as before, there is formed a threaded portion for attaching the bombe unit to the holder of the dispensing unit.
  • the inside of the mounting member 18 likewise forms a housing section within which the unstoppering unit 7 is slidably disposed.
  • the pointed-end member 10 provided in the unstoppering unit 7 is manipulated against the resilience of the spring 16 by the operating rod 15 inserted through the opening 12 in the mounting member 18 for forming a discharge orifice 11 in the sealing plate, which discharge orifice may be opened or closed as described above.
  • the sealing plate unstoppering unit 7 is slidably and rotatably mounted in the cylindrical end section 6 of the bombe housing 2 or in the housing section 8 of the mounting member 18.
  • the housing section 8 there may be provided in the housing section 8 a plurality of rib-like projections 19 engaging in the recesses 13 of the guide member 9 for restricting the rotation of the unstoppering unit 7.
  • the pointed-end member 10 acts on the sealing plate 3 at an approximately constant angular position for maintaining a uniform shape of the discharge orifice 11 in order to provide for more positive opening or closure of the discharge orifice 11.
  • the present invention is not restricted thereto but may comprise a number of modifications.
  • through- holes may be provided in place of the recesses 13 in the guide member of the unstoppering unit 7 for conducting the high pressure gas.
  • the mounting members 18 may be affixed by engagement with a threaded portion provided on the foremost part of the bombe 1. Since the mounting member 18 may in this case be formed by moulding, it may be fabricated easily, while the connection between the bombe 1 and the mounting 18 may also be effected easily.
