Flexible lid with opposable tabs and unique cutback securing feature

Abstract

A flexible lid with opposable tabs constructed from a pliable plastic or rubber compound. The lid incorporates a wall that extends for the entire circumference of the lid that consists of an angular cut back area which creates securing means for a container of similar diameter. Opposable tabs are incorporate to ease in the removal of the lid from a container for reuse. Tabs may also be used to assist in securing and gripping the lid.

1 . A base lid for a container comprising: 
 a body having a bottom wall and a side wall;    said side wall having an interior surface and exterior surface, the interior surface of the wall defining the opening; and    said body consisting of a tab positioned on the side of the body.    
   
   
       2 . The base lid of claims  1  further comprising: 
 the defining opening created by the body, side wall, and bottom defining a round opening.    
   
   
       3 . The base lid of  claim 2  further comprising: 
 an interior wall with recessed and protruding areas.    
   
   
       4 . The base lid of  claim 3  further comprising: 
 an interior wall which becomes thicker at a linear rate from the opening toward the bottom of the base lid the transitions to become thinner in an exponential manner until a predetermined thickness is achieved and then remains at a constant thickness until the base wall is reached    
   
   
       5 . The base lid of  claim 4  further comprising: 
 two tabs positioned on opposing sides of the body.    
   
   
       6 . The base lid of  claim 5  further comprising: 
 three or more tabs positioned equally distant from each other along the perimeter of the body.    
   
   
       7 . The base lid of  claim 5  further comprising: 
 said tabs positioned on opposing sides centered on the diameter of the round opening.    
   
   
       8 . The base lid claims  4 ,  5 ,  6 , or  7  further comprising: 
 said linear rate creating an interior protrusion is between 10 degrees and 20 degree.    
   
   
       9 . The base lid of  claim 8  further comprising: 
 said liner rate is 15 degrees.    
   
   
       10 . A base lid comprising: 
 a body having a bottom wall and a side wall;    said side wall having an interior surface and exterior surface, the interior surface of the wall defining the opening;    said body consisting of a tab positioned on the side of the body;    the defining opening created by the body, side wall, and bottom defining a round opening;    an interior wall with recessed and protruding areas;    said interior wall which becomes thicker at a linear rate from the opening toward the bottom of the base lid the transitions to become thinner in an exponential manner until a predetermined thickness is achieved and then remains at a constant thickness until the base wall is reached;    said linear rate creating an interior protrusion is between 10 degrees and 20 degrees.    
   
   
       11 . The base lid of  claim 10  further comprising: 
 two tabs positioned on opposing sides of the body.    
   
   
       12 . The base lid of  claim 10  further comprising: 
 three or more tabs positioned equally distant from each other along the perimeter of the body.    
   
   
       13 . The base lid of  claim 11  further comprising: 
 said tabs positioned on opposing sides centered on the diameter of the round opening.    
   
   
       14 . The base lid of  claim 10 ,  11 ,  12 , or  13  further comprising: 
 said liner rate is 15 degrees.
