<p>A bottle (10) for a jigger-style closure cap is formed by blow moulding an injection moulded preform, the bottle having a neck portion (14) with a cylindrical part (14A) on which is formed a screw thread 12. The neck portion further includes a flared skirt (20) which carries a ring (18) formed with ratchet teeth (16) adapted for co- operation with complementary ratchet teeth on a tamper proofing ring around the free edge of the jigger cap (not shown). The skirt (20) overlies an intermediate portion (24') which joins the neck portion (14) with the body portion (26') of the bottle. The neck portion (14) is given substantially its final form at the preform stage, whereas the intermediate (24') and body portions (26') are expanded by the blow mouldings operation. The expansion of the intermediate portion (24') brings it into firm engagement with the bottom of the skirt (20) so as to locate the ratchet teeth (16) radially and render the skirt solid with the remainder of the bottle. Alternatively, portion (24') may engage skirt (20) over substantially the whole of its length, and the skirt may be provided with circumferentially spaced apertures, Figures 6, 7 (not shown). <IMAGE></p> |
