A opening assembly ( 10 ) suitable for use on a can for containing carbonated beverages. The assembly ( 10 ) comprises a main part ( 14 ) with an oval opening ( 16 ). A flange ( 18 ) is provided around the underside of the opening ( 16 ), with a height inversely proportional to the diameter of the opening ( 16 ) at any point. A closure member ( 20 ) is provided comprising an upper part ( 14 ), cylindrical body part ( 30 ) which sliding fits through the opening ( 16 ), and an engagement member ( 34 ) on its underside. In a closed condition the engagement member ( 34 ) engages against the tallest part of the flange ( 18 ) to sealingly close the assembly ( 10 ). The closure member ( 20 ) can be rotated until the engagement member ( 34 ) is not engageable with the flange ( 18 ), and the member ( 20 ) can then be removed from the opening ( 16 ) to open the assembly ( 10 ). The member ( 20 ) can be replaced in the opening ( 16 ) and rotated to reclose the assembly ( 10 ). |
