Abstract: 448,119. Closures for bottles, collapsable tubes, and like containers. REST, J., 8, Telford Avenue, Streatham Hill, London. Nov. 30, 1934, Nos. 34470/34 and 7971/35. [Class 125 (iii)] In a closure, for bottles, collapsable tubes, and like containers suitably of plastic material or of metal, of the type comprising a rotatable closure member pierced with a conduit and provided with means whereby it can only rotate about one axis and with external means for manipulation, liquid tight packing being provided between the closure member and the neck, and the top of the neck being closed down on to the closure member to complete its bearing or housing, washer or eyelet means 6, 13 of substantially spherical shape, disposed above and below the closure member 2 between it and the neck 10, fit the closure member to ensure an air and liquid tight housing for it in the closed position, (both ends of the conduit 4 being completely enclosed), the lower washer or eyelet means seating on a flange or shoulder projecting inwardly from the base of the neck portion to form the discharge orifice 9, and having a neck 8 which fits snugly into said discharge orifice for anchoring and registering purposes, the closure member being thus irremovable from its bearing or housing ; and a projection or recess, groove or slot device coacts between the neck of the container and the closure member to compel the closure member always to rotate about one axis. The closure member is actuated by an external member 3 and has a groove 5 which coacts with a projection 14 from the upper washer 13. The conduit 4 may be offset from the centre of closure member and may taper towards its outlet. Instead of the member 3, an indentation having raised lips round its edges may be provided in the closure member for its manipulation. If desired, the conduit may taper and end in a semicircular shape inside the closure member, a small hole only giving access to the outside. The bore of this conduit may be channelled with grooves parallel to the axis of the conduit. A plug, smooth or .with helical grooves, fits the bore of the conduit and converts the closure member to an atomizing device when used on a container for liquids. In a modification, the neck 24, Fig. 6a of the container has grooves 25 parallel with the axis of the container, the grooves being flat sided as at 26 and tapered at 27. The top 29 of the container has an annular groove 30. A spherical closure member 31, Fig. 6c has lateral trunnions 32 to engage in the grooves 25. A washer 6 seats on the projection 28 with its neck 8 fitting into the orifice 35. The trunnions 32 project very slightly above the bottom of the groove 30. A washer member is disposed above the closure member in the groove 30, and the top of the neck of the container is closed down on to this washer to keep it in position. In a further modification, the neck of the container is not grooved, and the trunnions on the closure member cut their own grooves in the material of the neck when the closure member is forced into position. In practice the container is made by extrusion and is disposed on an arbor 37, Fig. 8, with a pin 38, the eyelet 611 being placed in position on the shoulder 28<11> and the orifice 41 of the closure member is threaded over the pin 38. A closing tool 39 with a sliding ram 40, spring loaded at 41 closes the top of the container down on to the closure member. Specification 428,229 is referred to.
