Pull tab system with additional gripping portions

Abstract

A pull tab system with additional gripping portions. The pull tab system may be implemented with containers such as can to provide a mechanism to open the can. The pull tab includes an underneath concave curvature that increases the free space available below the pull tab to enable users with disabilities and long fingernails to grip the underside of the pull tab from below the pull tab. The pull tab system also may include a cavity implemented in the top surface of the can that extends beneath and under the pull tab to provide additional free space to grip the pull tab from below the pull tab.

1 . A pull tab system for use as a mechanism to open a can, the pull tab system comprising:
 a pull tab with a front end, a rear end opposite the front end, a left side and a right side, the front end including a far-left point and a far-right point, the pull tab including a concave curvature beginning at the far-left point and terminating at the far-right point;   wherein when the front end is pulled upward the rear end causes the can to be opened.   
     
     
         2 . The pull tab system of  claim 1  further comprising a cavity implemented in a top surface of the can with a portion of the cavity extending beneath the front end of the pull tab. 
     
     
         3 . The pull tab system of  claim 1  wherein the concave curvature begins at the left side of the pull tab and terminates at the right side of the pull tab. 
     
     
         4 . The pull tab system of  claim 1  wherein the pull tab includes a cutout in an area between the front end and the rear end, the cutout defined by a front cutout edge and a rear cutout edge, the front cutout edge including the concave curvature. 
     
     
         5 . The pull tab of  claim 4  wherein the rear cutout edge includes the concave curvature. 
     
     
         6 . The pull tab system of  claim 1  wherein the left side of the pull tab includes a first chamfer comprising a first angled portion that begins at a first point along the left side and that terminates at the far-left point, and/or the right side of the pull tab includes a second chamfer comprising a second angled portion that begins at a second point along the right side and that terminates at the far-right point. 
     
     
         7 . The pull tab system of  claim 1  wherein the front end of the pull tab extends upward within a single plane that is generally perpendicular to a top surface of the can. 
     
     
         8 . The pull tab system of  claim 1  wherein the front end of the pull tab extends upward within a single plane that tilts towards the rear end of the pull tab at a non-perpendicular angle with respect to a top of the can. 
     
     
         9 . The pull tab system of  claim 1  wherein the concave curvature includes a peak, and the peak is about 1 mm to about 7 mm tall. 
     
     
         10 . The pull tab system of  claim 1  wherein the concave curvature includes a peak, and the peak is about 3 mm to about 5 mm tall. 
     
     
         11 . The pull tab system of  claim 1  wherein the shape of the pull tab from a perspective from above the pull tab is trapezoidal.
