ABSTRACT:
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).
