Abstract: A bottle comprises a body having an opening in an upper end for receiving fluid; a membrane provided to seal across the opening; and a receptacle sealingly secured to a surface of the membrane within the body. Separation of the membrane from the opening in the receptacle releases the receptacle such that the contents of the receptacle are released into the body.

Abstract: A glide castor comprises a two-part body assembly consisting of lower and upper mouldings fitted together. The lower moulding has a convex bottom ground-engaging surface and an integral upstanding boss with a bore for a mounting spindle. The upper moulding is of cap-like form and seats on a peripheral seating on the lower moulding. An integral inwardly projecting lip of the upper moulding provides snap-on engagement with said boss, thereby to hold the two mouldings together as an assembly.

Abstract: A castor has a domed wheel rotatably mounted about an inclined axis on a body itself pivotally mounted on or about a vertical mounting spindle. The wheel axis is offset laterally of the spindle axis and the wheel has a rim with a convex part-spherical ground-engaging surface. The body is moulded with an integral bearing boss and the wheel is moulded with an integral bearing boss, the bosses engaging one within the other to provide a bearing for the wheel. The spindle is located in a bore in the body and engages in a peripheral groove in the boss to locate the wheel axially with respect to the body. A sleeve-like portion of the body moulding concentric with and surrounding the boss provides an outer female bearing surface for the wheel boss.
