1,086,892. Caps for bottles &c. REXALL DRUG & CHEMICAL CO. Sept. 30, 1964 [Oct. 15, 1963], No. 39863/64. Heading B8T. A cap with one or more discharge openings is fitted over a cylindrical portion of a one-piece bottle &c., the cylindrical portion having either an eccentric filling-opening, or a filling opening with an eccentric extension, or a filling opening with an additional eccentric opening, the arrangement allowing the cap to be rotated to bring the discharge opening or openings into or out of register with the eccentric filling opening, the eccentric extension, or the additional eccentric opening. A plastics bottle is blow moulded with a wall 20, neck 22 and a neck extension 23 which is cut off to form a star-shaped filling-opening 26 bounded by a flange 24. The cap 28, which has discharge holes 30, is snapped on to the neck 22 and held in position by a rib 25 on the neck co-operating with an internal groove in the cap. The flange 24 which is slightly conical, forms a seal against the inside of the cap and rotation of the cap brings the holes 30 into and out of register with the apices of the hole 26. In a modification, the filling opening is keyhole-shaped, and the discharge openings comprise a single opening spaced from a group of smaller openings. |
