Definitions

  • This invention relates to a coupling for the dispensing of fluids from containers, in particular the dispensing of liquids from containers by the use of a pressurizing gas.
  • the present invention provides a coupling for use in the dispensing of fluid from a container wherein the liquid can effectively be sealed from atmospheric contamination.
  • a coupling for the dispensing of fluid from a container comprising first and second mating coupling parts which are adapted for connection and disconnection, the first mating coupling part comprising a plug adapted for connection to a container aperture and defining first and second fluid flow passages therein, and a body for sealing coupling to said plug and comprising third and fourth fluid flow passages therein, said plug and body having means adapting same to be sealingly coupled together whereby the first and third passages are in fluid communication, and are sealingly isolated from the second and fourth fluid passages which are also in fluid communication whereby, when the coupling is used with a container which is sealed apart from the aperture receiving the plug, fluid can be discharged from the container through either the first and third passages or the second and fourth passages by pressurizing or vacating the container through the others of said second and fourth and first and third passages.
  • the plug may be circular sectioned and may have on its outer surface a screw thread adapting it to be screw threaded to a threaded neck defining said container aperture.
  • the plug may be provided with an axial bore, part of which defines said first passage, and the second passage is defined by one or more radial bores intersecting the axial bore, and lying to the side of the plug which is inserted into the container so that the radial bore or radial bores will lie inside the container when the plug is screwed thereto.
  • the plug and body preferably are constructed from synthetics plastics material, such as for example a low density polyethylene.
  • a container 10 holding for example a sterile and valuable liquid 12 which is required periodically to be dispensed from the container 10 to an outlet pipe 14.
  • the method of dispensing is to supply gas under pressure through a supply pipe 16 as indicated by arrow 18, so that the fluid is dispensed as indicated by arrow 20.
  • the gas under pressure is supplied through a coupling 22 according to the present invention which has an outlet permitting the flow of gas under pressure as indicated by arrow 24 into the head space 26 above the liquid 12, and a dip tube 28 dips into the liquid and extends to the base of the container, the dip tube serving as a feed means enabling the flow of liquid up the dip tube and through the coupling 22 and eventually to pipe 14.
  • Figs. 2 to 5 show respectively in Figs. 2 and 3 a plug portion of the coupling, and in Figs. 4 and 5 a body portion.
  • the plug portion shown in Figs. 2 and 3 forms a female part, whilst the body portion forms a male part which is adapted to be inserted into the plug to establish sealing connection therewith.
  • the plug which is indicated generally by reference numeral 30 is a one-piece plastics moulding of circular cross-section, and is provided with an axial bore 32 which has sections of different configuration and, from the bottom upwards in Fig. 2 comprises a first cylindrical section 34 which is threaded, a frustoconical sealing section 36 which increases in diameter in an upwards direction, a cylindrical closure cap section 38 which is threaded in order to receive a closure cap 40 for the closing of the bore when the coupling parts are disconnected, and the contents of the container 10 have to be protected, and a frustoconical section 42 which increases in diameter to the upper end face 44 of the plug.
  • each of the ribs 46 and 48 is provided with a slot 50, 52 open at one side only of each rib for the receipt of tongues on the body of Figs. 4 and 5 for the coupling together of the plug and body as will be described hereinafter.
  • the interior 58 forms an extension of the axial bore 32 so that in use the displaced fluid can travel up the inside of the sleeve 54 and into the axial bore 32.
  • the plug 30 is provided with screw threads 60 enabling the plug to be screw threaded into a neck 62 defining the aperture in the container 10 (see Fig. 1).
  • the plug When the plug is screwed into the neck 62, it sealingly engages same preventing the ingress of atmosphere into the container between the plug and neck.
  • the cap 40 is screwed sealingly into engagement with the threaded bore portion 38 in order to seal off the bore 32 and prevent any contact between the liquid inside the container and the atmosphere.
  • the body 70 is a block of plastics material which is similar in nature to the material used for the plug 30.
  • the body is of circular cross-section and comprises a main portion 72 and a cylindrical projecting portion 74 of reduced diameter which fits into the bore 32.
  • the portion 74 in an upwards direction in Fig. 4 comprises a frustoconical end 76 having a lower groove 78 which receives an O-ring seal 80 defining a sealing surface, and a second O-ring 82 seats on a shoulder 84 at the other end of the frustoconical end 76 where a cylindrical portion 86 meets the frustoconical end 76.
  • a further O-ring seal 88 may be provided on a shoulder 90 between the cylindrical portion 76 and a further but increased diameter cylindrical portion 92 which connects with the main body part 72.
  • Cylindrical portion 92 has a pair of diametrically opposite locking tongues 94, 96 which are spaced from the main body portion 72 so as to be capable of engaging in the slots 50 and 52 as described hereinbefore.
  • the body is provided with through passageways 96, 98, the passage 96 leading from the end face of end 76 as indicated by reference 100 and passes axially through the body 70 until it turns at right angles and leads to a side outlet 102.
  • the passageway 96 is of reducing diameter from the outlet 100 to the region 104 and from region 104 to outlet 102 it is of constant diameter.
  • the passageway 98 leads axially through the body from the top surface 106 thereof until it turns at right angles as indicated at 108 and exits at outlet 109 between the O-ring seals 80 and 84 in the frustoconical wall of end 76.
  • the passageway 98 is of constant diameter until it reaches region 110 when it is of constantly reducing diameter until it reaches the right angled portion 108.
  • the two flow passages are mutually sealed one relative to the other, insofar as the sealing rings 80 and 84 engage the sealing surface 36 on opposite sides of the radial bores 55.
  • the flow passages connecting the interior of the container and the exterior of the container can be used in opposite fashion.
  • gas under pressure can be passed through the pipe 14, for the discharge of liquid through the pipe 18, but in this connection it may be necessary to provide for a dip tube connection to the ports 55.
  • liquid can be sucked from the interior of the container through pipe 14 as long as pipe 16 is coupled to the supply of gas to replace the liquid withdrawn from the container 10.
  • the gas which is used for contacting the liquid for propelling same from the container or for making up the space created by withdrawal of the liquid from the container may be of a type which does not react with or contaminate the liquid in the container 10.
  • FIG. 6 and 7 The embodiment of the body shown in Figs. 6 and 7 is essentially similar to that shown in Figs. 4 and 5 except that the main portion 72 of the body is hollowed out as indicated at 112 in order to save material, and this means that the discharge outlet 102 is located at a lower position in the body.
  • Other parts already described in relation to Figs. 4 and 5 which are also present in the Figs. 6 and 7 arrangement have similar reference numerals.
  • Fig. 7 shows that the exterior of the main body part 72 is provided with ribs 114 to facilitate the rotation of the body by hand.
