Abstract
A flip-up pop-tab in which a partially detachable portion of a lid of a can is separated from the can and hinged away from the opening created in the lid is described.
Claims17
A pop-top for a can, the pop-top comprising:
- a lid, the lid having a panel outlined via a score line (30);
- and
- an opening means attached to the panel at an attachment point, the opening means comprising a lever arm (52) and a panel cover (53), the panel cover (53) having an outer edge that extends over a portion of the lid that is adjacent to and contiguous with the score line (30) outlining the panel, the opening means configured to apply a force to the lid effective to cause the score line (30) to break and the panel to lift away from the lid in a direction toward the lever arm (52);
- wherein the panel cover (53) of the opening means is at least partially semi-circular in shape and shaped to correspond to a majority of the overall shape of the panel of the lid and is sized to be larger than the overall shape of the panel;
- wherein the panel cover (53) is configured to apply pressure to the lid outside the score line (30) when the opening means is utilized;
- wherein the score line (30) has a first score line end and a second score line end and wherein the first score line end is adjacent to an attachment point of the panel;
- wherein between the first score line end and the second score line end, the score line (30) is formed behind closer to a center of the lid and around the attachment point and then towards an edge of the lid, then curving in a semi-circular shape toward an opposite lateral side of the lid and thereby forms a boundary of the panel;
- wherein the score line (30), once unsealed by the lever arm (52) raising the attachment point of the panel pivoting about the panel cover (53) contact with the lid outside of the boundary of the panel, allows the panel to be lifted upward relative to the lid in a direction toward the lever arm (52) and hinged away from the opening created in the lid and thereby exposing an internal face of the panel;
- and
- wherein the opening means comprises a second class lever with the panel cover (53) serving as a fulcrum at one end, the lever arm (52) distally presented at a manually-moved opposite end, and the attachment point to the opening means being between the fulcrum and the manually-moved opposite end presenting resistance that results in a shearing of the lid along the score line (30) between the attachment point and the manually-moved opposite end.

A method of opening a pop-top can comprising:
- providing an opening means attached to a lid of the pop-top can, the opening means comprising a lever arm (52), a panel cover (53), and one or more arms (55), the panel cover (53) having an outer edge that extends over a portion of the lid that is adjacent to a panel defined by a score line (30) in the lid;
- wherein the opening means comprises a second class lever with the panel cover (53) serving as a fulcrum at one end, the (52) distally presented at a manually-moved opposite end, and the attachment point to the opening means being between the fulcrum and the manually-moved opposite end presenting resistance that results in a shearing of the lid along the score line (30) between the attachment point and the manually-moved opposite end;
- wherein each of the lever arms (52) is configured to apply pressure to the lid outside the score line (30) when the opening means is utilized;
- wherein when the panel is in a closed position and the score line has not been broken, the lever arm (52) and the panel cover (53) are adjacent to and substantially contiguous to the panel;
- lifting the lever arm (52) to a position perpendicular relative to the lid effective to press the one or more arms (55) of the opening means down on the lid outside the score line;
- continuing to lift the lever arm (52) to cause the lever arm (52) to fold forward towards the panel raising the attachment effective to cause the score line behind closer to a center of the lid and around the attachment point to break and create an opening between the panel and the lid;
- and
- pushing the lever arm (52) back towards the lid in a direction opposite from a direction in which the lever arm (52) was lifted effective to pull the panel cover (53) and the panel up and away from a plane in which the lid lies and to expand the opening along the score line.
