<p>A pressurisable beverage container comprises a wide-mouthed receptacle forming a drinking vessel (10) and a screw-threaded closure cap (28). The cap is arranged to enter the mouth of the vessel to seal against a convergent internal surface of the vessel and enable the vessel to be pressurised. The vessel can be vented by means of a ring pull device (54) to reduce the internal pressure before removing the cap from the vessel. A jetting device (44) is secured to the underside of the cap, being activated upon venting the vessel prior to removal of the cap from the vessel. <IMAGE></p> |
