Abstract
The lid of a beverage can has two punched segments, breaking of which forms the respective openings for allowing the liquid to flow out and the air to enter. Breaking of these punched parts is performed by pivoting upwards a main ring mounted on a rivet of the lid and, after breaking open the punched part, pushing downwards a secondary lever with cutting pressure pieces which cut into the punched parts so as to cause breakage thereof. The said secondary lever is mounted on the same rivet, having an end segment which rests against a stop of the ring in order to prevent in the rest condition the pressure pieces cutting into the punched parts. In another simpler embodiment, the secondary lever is dispensed with, so that the pressure piece is incorporated along the contour of the associated main ring.
Claims24
A double opening system for a beverage can, wherein a corresponding lid of the beverage can features a first die cut configured to be torn so as to establish a liquid outlet orifice for liquid contained in the can, the tearing of the first die cut being performed by an upward tilting about a tilting axis of a main ring mounted on a rivet on the lid;
- wherein the lid incorporates at least a second die cut whose tearing constitutes an air entrance orifice, the second die cut delimits a portion of the lid facing a cutting hammer formed on a secondary lever and configured to tear the second die cut after tilting the main ring downward until the main ring reaches an initial resting position, after having first torn the liquid outlet orifice;
- and wherein the secondary lever is mounted with the same rivet as the main ring but has a tilting axis different from the tilting axis of the main ring;
- said secondary lever configured to move the cutting hammer for tearing the second die cut by pressing downwards on said secondary lever after tilting the main ring upwards and tearing the first die cut and wherein the cutting hammer is provided on said secondary lever.
A double opening system for a beverage can, comprising a lid, the lid comprising a first die cut that defines a first opening in the lid when the first die cut is torn and a second die cut that defines a second opening in the lid when the second die cut is torn;
- a first lever attached to the lid by a coupling and configured to pivot about a first axis so as to tear the first die cut;
- a second lever attached to the lid by the same coupling and configured to pivot about a second axis so as to tear the second die cut, wherein the second axis is spaced from the first axis so that upon pivoting of the first lever and the second lever, and end of the first lever traces a first arc and an end of the second lever traces a second arc, the first arc and the second arc being nonconcentric and on a same side of a vertical axis passing through the coupling;
- wherein the second lever comprises a downward facing hammer configured to tear the second die cut when pressed into the second die cut.
