  • the operatively upper end of the closure member (6) has an integral finger grip (9) whilst the operatively lower end (10) forms the tap outlet.
  • outlet member is such that the spike can be introduced through the wall (11) of a flexible packaging bag (12) of liquid as illustrated progressively in Figures 1 , 2 and 3, and as more fully described in my international patent application WO 01/00503.
  • a circumferential series of apertures (13) that in this instance are formed by crossed helically extending integral webs of material that between them form a lattice defining a series of circumferentially elongate diamond shaped apertures.
  • the material is preferably sufficiently flexible so that the apertures can be substantially closed by the application of axial force between the spike and tubular member whilst the spike is being passed through the wall of the packaging bag.
  • the same effect could be achieved by utilizing a plurality, typically two, three or four, of helically extending integral webs of material that are parallel and not interconnected by any crossed webs of material.
  • the apertures are located at a slightly enlarged inner region (14a) of the tubular member and this enlarged zone communicates with the outer surface (14) of the remainder of the tubular member through an endless clamping surface (15) encircling the outlet member.
  • the clamping surface could be of simple truncated conical shape.

  • the diameter of the aperture (20) is approximately the same in that the outer diameter of the slightly enlarged region (14a) is of the outlet member so that the combined clamping element can be introduced onto the outlet member by pressing the enlarged region through it. The combined clamping element is then held substantially captive on the outlet member.
  • the mounting bracket has a surrounding groove (21) in its peripheral edge for receiving an edge of an aperture through the wall of a box (not shown) in which a liquid packaging bag is to be stored in well known manner.
  • the mounting bracket can be adapted for use in combination with a box as described in my international patent application number WO 01/00504 or WO 02/092462.
  • the combined clamping element and mounting bracket is orientated such that the endless clamping edge (17) is directed for cooperation with the clamping surface (15) encircling the outlet member.
  • the flanges (19) extend from the bracket in the direction away from the endless clamping edge (17) and each has an outer end edge (23) that is formed into a shaped cam surface for cooperation with the transverse tap body (5) that acts as a cam follower.
  • the arrangement is such that the tap body, in one orientation, fits between the two flanges (19) so that an appreciable amount of relative axial movement is enabled between the combination clamping element and the outlet member, as shown clearly in Figures 1 and 2.
  • the tap body is located in this position during the penetration procedure illustrated in Figures 1 and 2 so that sufficient of the

  • the outlet member is moved axially outwards so that the combination clamping element, and thus its endless clamping edge (17), moves towards the clamping surface (15) on the outlet member.
  • the cam surfaces (23) are arranged such that when the tap body (5) is located approximately at the outer ends of the flanges (19) it can be rotated by 90 degrees and the cam surfaces (23) cooperate with the tap body as a cam to pull the outlet member and in so doing clamp a doubled over ring (25) of the material of the flexible packaging bag between the endless clamping edge (17) and the clamping surface (15) as shown clearly in Figure 3.
  • cam surfaces (23) are shaped such that a snap lock is achieved in the final installed position of the tap in which it is operatively vertical, as shown in Figure 3, as opposed to being in a position at right angles thereto during the procedure that is illustrated in Figures 1 and 2.
  • a highly effective seal is thereby achieved in a simple and substantially foolproof manner.
  • the arrangement can accommodate any normal fluctuations or differences in thickness of materials of different packaging bags.
  • P0152PCT 2003-02- 18 flanges and their cam surfaces are omitted and replaced by a pair of diametrically opposite slots or grooves in the inner surface of a tubular wall forming the clamping element and that are indicated in Figure 5 as external slots (27).
  • Each slot extends axially and has a transverse branch slot indicated by numeral (27a), to form a clamping and locking arrangement that cooperates with pins or lugs (28) that extend radially out of the side wall of the outlet member (29).
  • Figure 6 illustrates a similar arrangement but one in which the slots or grooves are replaced by a helical slot or groove (30) that cooperates with pins or lugs (31) such that the helical slot or groove forms the cam surface and the pins or lugs form the cam follower.
  • some sort of catch or stop arrangement (32) is provided for arresting the pins or lug in a final position in which the bag is effectively clamped.
