Abstract
A container, particularly in the form of a beverage can, which has a drinking opening preparation in its upper lid wall, and may be reclosed after being opened by a rotary lid closure. Means are provided for coupling the rotary lid closure to the lid wall when the lid wall recedes somewhat after opening the container so that the drinking opening made can be reclosed sealingly.
Claims13
A container comprising:
- a rotationally symmetrical wall region;
- a lid wall having a circular circumference and being fixed with an edge seam to said rotationally symmetrical wall region along the circumference thereof;
- a bounded region of said lid wall extending between an axis of rotation and the circular circumference of said lid wall and being enclosed by a predetermined breaking line which, once broken open, releases a single drinking and pouring opening;
- a depression having a sloping surface which is formed by wall portions of said lid wall within said predetermined breaking line;
- a rotary lid closure which includes a rotary sliding wall which spans said lid wall, an opening cut out therein, and a boss for riding on said sloping surface so as to break open said drinking and pouring opening;
- means for supporting said rotary lid closure upon said edge seam of said lid wall when said rotary lid closure is actuated for breaking open said drinking and pouring opening, and
- means for coupling said rotary lid closure to said lid wall such that said rotary lid closure follows said lid wall when the same recedes somewhat in direction of the container interior due to decreasing inner pressure in the container after breaking up of the drinking and pouring opening.
