Connector, particularly for casks

A method of fitting a connector to an opening in container, particularly a cask, through liquid is discharged, in use, wherein the connector comprises a bush having a closed end and a weakened portion, an inner thread and an inner deformable portion, sealing means, and an insert screw-threadedly engageable within said bush, the method comprising positioning said bush in said opening with said sealing means disposed around said bush at the position of said inner deformable portion, and threadedly engaging said insert into said bush so that it deforms said inner deformable portion thereby effecting compression, and thus sealing of said sealing means between said bush and the container.

A connector for a container, particularly a cask, comprising a bush, intended to be received in an opening in the container through which liquid is discharged, in use, the bush having a closed end with a weakened portion, an inner thread and an inner deformable portion, sealing means intended to be disposed between the exterior of the bush and the interior of said opening at the position of said deformable portion, and an insert screw-threadedly engageable within said bush so as to deform said deformable portion, thereby effecting compression, and thus sealing, of said sealing means between said bush and the container, the connector also comprising a further insert which is screw-threadedly engageable within said insert to a position where cutting means of said further insert cut through said weakened portion of the closed end of the bush to provide an opening from the container for liquid to discharge through the further insert and wherein the weakened portion is an annulus, and the weakening allows the centre part of the membrane to be cut out by the cutting means of the further insert.
