Abstract

A senior-friendly child-resistant cap includes an inner cap having an axis and an outer cap having a periphery defining an outside diameter. The outer cap coaxially surrounds the inner cap and the outer cap is rotatable and axially movable with respect to the inner cap so that axial pressure and rotation of the outer cap rotates of the inner cap. The outer cap includes lugs extending outwards from the periphery to improve grip and at least some of the lugs extend radially outward from the periphery a distance within the range of 3% to 6% of the outside diameter to offer a user improved rotational leverage.

Claims

exact text as granted — not AI-modified
1 . A child-resistant cap, comprising:
 an outer cap having an axis, a periphery and an outside diameter;   an inner cap;   the outer cap coaxially surrounds the inner cap, the outer cap being rotatable and axially movable with respect to the inner cap so that axial pressure and rotation applied to the outer cap rotates the inner cap;   the outer cap periphery includes lugs; and   at least some of the lugs extend radially outward from the periphery a distance of at least 3% of the outside diameter.   
     
     
         2 . A child-resistant cap as set forth in  claim 1 , wherein the at least some of the lugs extend from the periphery a distance of at between 4% and 6% of the outside diameter. 
     
     
         3 . A child-resistant cap as set forth in  claim 1 , wherein the at least some of the lugs extend from the periphery a distance of approximately 5% of the outside diameter. 
     
     
         4 . A child-resistant cap as set forth in  claim 1 , wherein the at least some of the lugs have a width within the range of 0.06 to 0.15 inches. 
     
     
         5 . A child-resistant cap as set forth in  claim 1 , wherein the at least some of the lugs have a length, the length has a generally uniform curvature with a radius of curvature of less than 0.3 inches. 
     
     
         6 . A child-resistant cap as set forth in  claim 1 , wherein the at least some of the lugs have a length, the length has a generally uniform radius of curvature of approximately 0.226 inches; and
 the at least some of the lugs have a top portion having a top portion radius of curvature, the top portion radius of curvature being within the range of 0.150 to 0.170 inches.   
     
     
         7 . A child-resistant cap, comprising:
 an outer cap having a axis, a periphery and an outside diameter;   an inner cap;   the outer cap coaxially surrounding the inner cap, the outer cap being rotatable and axially movable with respect to the inner cap so that axial pressure and rotation applied to the outer cap enables rotation of the inner cap;   the outer cap periphery includes lugs; and   at least some of the lugs extend from the periphery a distance of at least 3% of the outside diameter and these lugs are spaced at an angle of at least thirty degrees apart.   
     
     
         8 . A child-resistant cap as set forth in  claim 7 , having ten lugs extending from the periphery a distance of at least 3% of the outside diameter and these ten lugs are spaced are spaced at an angle of thirty-six degrees apart. 
     
     
         9 . A child-resistant cap as set forth in  claim 7 , having eight lugs extending from the periphery a distance of at least 3% of the outside diameter and these eight lugs are spaced are spaced at an angle of forty-five degrees apart. 
     
     
         10 . A child-resistant cap as set forth in  claim 7 , having six lugs extending from the periphery a distance of at least 3% of the outside diameter and these six lugs are spaced at an angle of sixty degrees apart. 
     
     
         11 . A child-resistant cap, comprising:
 an outer cap having an axis, a periphery and an outside diameter;   an inner cap coaxially disposed within the outer cap, the inner cap normally being rotatable and axially moveable within the outer cap, wherein axial pressure and rotation applied against the outer cap rotates the inner cap; and   the outer cap includes eight lugs extending radially outwards from the periphery, and the lugs are uniformly spaced at an angle of 45 degrees apart.   
     
     
         12 . A child-resistant cap as set forth in  claim 11 , wherein the at least some of the lugs extend from the periphery a distance of at between 4% and 6% of the outside diameter. 
     
     
         13 . A child-resistant cap as set forth in  claim 11 , wherein the at least some of the lugs extend from the periphery a distance of approximately 5% of the outside diameter. 
     
     
         14 . A child-resistant cap as set forth in  claim 11 , wherein the lugs have a length, the length has a generally uniform curvature of less than 0.3 inches. 
     
     
         15 . A child-resistant cap as set forth in  claim 11 , wherein the lugs have a length, the length has a generally uniform radius of curvature of approximately 0.226 inches; and
 the lugs have a top portion having a top portion radius of curvature, the top portion radius of curvature being within the range of 0.150 to 0.170 inches.   
     
     
         16 . A child-resistant cap as set forth in  claim 11 , wherein the at least some of the lugs have a length, the length has a generally uniform radius of curvature of less than 0.3 inches;
 the lugs have a beveled top portion.   
     
     
         17 . A child-resistant cap as set forth in  claim 11 , wherein the lugs have a thickness within the range of 0.08 to 0.15 inches. 
     
     
         18 . A child-resistant bottle, comprising:
 a bottle having a threaded neck;   an inner cap having a threaded interior for mating with the threaded neck of the bottle, and an axis;   an outer cap having a periphery defining an outside diameter, and a top;   the outer cap surrounding the inner cap, the outer cap being rotatable and axially movable with respect to the inner cap so that axial pressure and rotation of the outer cap rotates the inner cap;   the outer cap includes lugs extending outwards from the periphery; and   at least some of the lugs extend radially outward from the periphery a distance of at least 3% of the outside diameter.   
     
     
         19 . A child-resistant bottle as set forth in  claim 18 , wherein the at least some of the lugs extend from the periphery a distance of at between 4% and 6% of the outside diameter. 
     
     
         20 . A child-resistant cap as set forth in  claim 18 , wherein the at least some of the lugs extend from the periphery a distance of approximately 5% of the outside diameter.
