Redesigned Pull Tab Systems

Abstract

Improved pull tab systems may include an upper apex curve system (A) with lateral and downward legs (AB) and (AC) with lower curve systems (B) and (C) with the lower curved systems or lower ends sometimes raised above the surface (S) of the can top. Lower legs (AB) and (AC) may be angled in the range of 10 to 35 degrees. The distance between the upper apex (A) and line (BC) may be in the range of 1 to 6 mm. The upper apex curve system (A) and/or lower curve systems (B) and (C) may include curvilinear and/or compound curvilinear corners. The improved pull tab systems enable easier finger or tool access for lifting a tab so as to open a container.

What is claimed is: 
     
         1 . A tab system used upon containers to keep a container closed and used to open a container, the tab system comprising;
 a) a proximal section comprising a tab section having a curved apex (A) with the apex having a first leg ending at first curved section (B) and the apex having a second leg ending at a second curved section (C).   
     
     
         2 . The tab system of  claim 1  wherein the first and second curved sections (line BC) are disposed over a top surface (S) of the container. 
     
     
         3 . The tab system of  claim 2  wherein the first and second curved sections (line BC) are disposed over the top surface (S) of the container at a distance in the range of 1 to 15 mm. 
     
     
         4 . The tab system of  claim 3  wherein a line (line BC) between the first and second curved sections is disposed at a distance from the curved apex in the range of 1 to 15 mm. 
     
     
         5 . The tab system of  claim 4  wherein the angle of the curved apex (A) is in the range of 15 to 50 degrees from the first curved section and the second curved section. 
     
     
         6 . The tab system of  claim 5  wherein the angle at the first curved section with respect to the second curved section and apex is in the range of 15 to 50 degrees. 
     
     
         7 . The tab system of  claim 6  wherein the curved apex comprises a compound curvilinear curve. 
     
     
         8 . The tab system of  claim 7  wherein the first and second curved sections each comprise a compound curvilinear curve. 
     
     
         9 . The tab system of  claim 8  wherein the first and second curved sections define an inverse V void. 
     
     
         10 . The tab system of  claim 9  wherein the proximal section is attached to a medial section, with the medial section attached to the container. 
     
     
         11 . The tab system of  claim 10  with the medial section attached to a distal section, with the distal section disposed over the container in an area where the container compromises a scored section.
