Definitions

  • the invention relates to a flow connection, particularly between respective interiors of two members which are connected, or to be connected, with a flow path between them.
  • a drinks holder of the kind in which a flexible reservoir or bag of, say, liquid is held in a box, and the reservoir and box is to be connected to a dosing device for a measured distribution of the liquid from the reservoir in say a drinks machine.
  • Such boxes with reservoirs therein are replaceable and it is accordingly essential that the contents of the reservoir remain sealed until the box is mounted in a drinks machine ready to be dispensed.
  • a set of parts for providing a flow path connection between respective interiors of two members comprising a support part for mounting on one member, and a piercing part cooperable with the other member and with the support part, the arrangement being such that when the two pans are assembled piercing means of the piercing part pierces the one member on relative movement of the two parts.
  • the support part may have external engagement means releasably cooperable with engagement means of a mounting device of the one member.
  • the respective engagement means may comprise snap-engageable means. This provides for ease of use and manufacture.
  • the two parts may be interengageable by cooperable means whereby the piercing part may move telescopically with respect to the support part.
  • This provides a positive action, particularly as the cooperable means may comprise screw thread means.
  • the piercing means may comprise a tip of the piercing part. This provides a relatively simply integral piercing means.
  • detent means of one part preventing undesired relative movement of the two parts in a particular direction. This provides for ease of transport and storage.
  • the detent means may comprise an external shearable stop means on the piercing part. This provides for relatively simple operation to pierce a member.
  • seal means whereby the support part and piercing part may be sealed together when the piercing part is in use moved to a fully piercing position relative to the support part.
  • seal means may comprise an annular bead on one part and a complementary groove on the other part. This makes for an effective seal, and the bead may be on the support part.
  • the piercing part may comprise a seating for cooperation with the other member, which seating may comprise a well in which the other member is received with a push fit, suitably a substantially leak-proof interference fit.
  • a flow path connection comprising a set of parts as hereinbefore defined, with the two parts being assembled together.
  • One member may comprise a reservoir pierced by the piercing member.
  • the one member may also comprise a container of flowable material, for example a liquid such as wine.
  • the other member may comprise a dosing apparatus.
  • Fig. l is a side elevational view of a first embodiment of a set of parts, assembled, according to the invention
  • figs. 2 and 3 are respectively a longitudinal section view and a plan view of a support part of a second embodiment of a set of parts according to the invention.
  • Figs. 4, 4A and 5 show piercing part of the second embodiment, Fig. 4 being a longitudinal sectional view, Fig. 5 a plan view, and Fig. 4A an enlargement of part A of Fig. 4.
  • piercing means such as a slant tip 6 of the piercing part 5 pierces the bag 2a of the one member 2a, 2b on relative movement of the two parts 4, 5.
  • the bag or reservoir 2a is of pierceable plastic or the like and is hermetically sealed and contains a liquid, say wine.
  • a flange 7 Secured to the exterior of the bag 2a by a flange 7 is a mounting device or boss 8 which, by a substantially parallel flange 9, is secured to the inner surface of the box 2b, which can suitably be made of cardboard or the like.
  • the boss 8 is mounted to surround a hole 10 through the box 2b and to provide a passage to the exterior surface of the bag 2a.
  • the support part 4 and piercing part 5 are formed from a suitable material such as plastic.
  • the support part 4 and boss 8 are releasably engaged by releasably cooperable means in the form of external profiles 11 on the support part 4 snap engageable in complementary recesses 12 in the boss 8.
  • the support part 4 also has internal means in the form of a screw thread 13 which is cooperable with an external screw thread 14 forming cooperable means of the piercing part 5.
  • the screw thread 14 is carried on a tubular part 15 of the piercing part 5, which tubular part 15 terminates in the slant tip 6 forming the piercing means.
  • a transverse hole 16 in the tip 6 provides for complete emptying of the bag 2a in use.
  • the support part 4 has a flange 17 which abuts the external surface of the box 2b, the flange 17 having seal means in the form of an annular bead 18 of triangular section which is cooperable with a complementary groove 19 of a facing part of the piercing part 5.
  • the set of parts 1 also comprises detent means in the form of a shearable stop 20 mounted externally on the tubular part 15 of the piercing part 5 and which prevents unwanted movement towards the bag 2a.
  • the piercing part 5 also has a seating 21 in the form of an enlarged part which receives with a leak-proof interference fit the second member or dosing apparatus 3.
  • the support part 4 and piercing part 5 are screwed together so that the stop 20 abuts the outer surface of the flange 17 of the support member 4.
  • the dosing apparatus 3 is mounted in the seating 21 and the support part 4 is snap engaged in the boss 8, the stop 20 preventing the piercing tip 6 from engaging the bag 2a.
  • the two members 2a, 2b and 3 are thus connected together, and can be stored and transported, the bag remaining intact.
  • the whole assembly can be mounted for example on a drinks dispensing apparatus (not shown).
  • the piercing part 5 is then screwed into the support part 4, so shearing the stop 20 and causing the tip 6 to pierce the bag 2a cleanly and quickly.
  • the annular bead 18 enters the groove 19 and seals the parts together 4, 5.
  • the two members 2a, 2b and 3 are then connected with a flow path connection between them via the assembled set of parts 1.
  • the support part 4 has flats 22 which locate in and on the box 2b to hold the assembly firm whilst screwing down and hence piercing the bag 2a.
  • the parts 4 and 6 are made from plastic.
  • the support part 4 is similar to that of the first embodiment, in having profiles 11 and an internal screw thread 13.
  • the piercing part 5 is similar to that of the first embodiment, one of the main differences being that there is a base or flange 101 which has projecting therefrom a plurality (in the embodiment, four) of projecting flexible and resilient fingers or teeth 102.
  • teeth 102 are arranged circumferentially of the flange 101 so as to be able to engage in teeth or stops 103 of the support part 4, these teeth or stops 103 being arranged circumferentially of and projecting inwardly of a wall 104 defining a well 105 in which the flange 101 is received.
  • the teeth 103 are unequally spaced angularly so ensuring that any two of the fingers 102 are always in contact with diametrically opposite teeth 103.
  • the arrangement is such that when the members 4, 5 are assembled and the piercing part 5 is rotated relative to the support part 4, the fingers 102 flex and click over the teeth 103 until the two parts 4, 5 are firmly screwed together to the desired extent.
  • the arrangement of the teeth 103 is then such that the fingers 102 lock behind the teeth, and unscrewing is prevented or hindered. Thus if there is no contact in the screwed- up position, any rotation of about a V ⁇ revolution will ensure that opposite fingers 102 come into contact with opposite teeth 103, thereby preventing undesired unscrewing of the two parts 4, 5.
  • the teeth 103 and fingers 102 thus provide an ami rotational means.
  • the crests of the screw thread 14 of the piercing part 5 are flat as in the first embodiment, but in the second embodiment, there are flattened thread crests 105 of the internal thread 13 of the support part 4.
  • This protrusion or pip 106 is resilient, and, when the two parts 4, 5 are screwed together, is forced to one side, and rides onto or presses against a flat 105 of the thread of the support part 4. This prevents the two parts 4,5 from being unscrewed by rattling down or up, in a condition before piercing of a bag.
  • the protrusion or pip 106 is thus essentially a damper means against vibration in use.
  • stop 20 may be replaced by a removable or frangible membrane such as a tear off strip.
  • the fingers may be unequally spaced, and the teeth equiangularly spaced.
  • any flowable material such as a particulate material, for example a food powder, or gas with suitable seals, or liquid other than wine.
