Abstract: A resealable closure device (10) for use on metallic cans includes a metallic end wall (12) having an opening (24) surrounded by an upwardly extending and outwardly flaring beaded flange (22). The flexible closure element (14) includes a central panel (34), a lever portion (36) and a connecting portion (38) connecting the lever portion to the central panel; the closure device may be molded in an inverted umbrella position which is capable of being inverted to engage the flange of the opening; a skirt portion (48) is provided on the interior side of the central panel of the flexible closure element to provide a degree of resistance to removal of the closure device from the opening by user.

Abstract: A method of die-necking the open end (23) of a can body to form a reduced diameter neck (22) having a smooth profile comprising forming a reduced neck at the open end of the cylindrical sidewall (21) of the can body by engaging the open end of the sidewall with a die having a multi-radius (R1,R2) forming profile, with each successive radius from the entrance to the exit of the die being smaller than the previous radius and with the angle (B,C) through which each successive radius extend being equal to or smaller than the angle of the previous radius. Then a subsequent die-forming stations, forming progressively smaller reduced diameter necks (40,60,84,86,88,25) by a series of dies, all of which preferably have the same multi-radiused forming surface profile which virtually eliminates the undesirable formation of pleats in the final neck configuration.

Abstract translation: 一种使罐体的开口端（23）颈缩的方法，以形成具有平滑轮廓的直径缩小的颈部（22），包括在罐体的圆柱形侧壁（21）的开口端处形成减小的颈部，颈部缩小 将侧壁的开口端与具有多半径（R1，R2）形成轮廓的模具接合，其中从模具的入口到出口的每个连续半径小于先前的半径，并且具有角度（B，C ），每个连续的半径延伸通过其等于或小于先前半径的角度。 然后，随后的模具形成站通过一系列模具形成逐渐变小的缩小直径的颈部（40,60,84,86,88,25），所有这些模具优选地具有相同的多圆弧形成表面轮廓，其实际上消除了 在最终颈部构型中不希望形成褶皱。
