Shelved Land for a Container Neck

Abstract

A device and container for improving the connection of a lid to a container by providing for a shelved container neck. The neck includes a shelved land on the top surface of the container neck which provides for an increased radial thickness to the top surface of the container neck.

1 . A device for improving the attachment of a screw on lid to a container, the device comprising:
 a container neck, being generally circular in shape;   at least one projection, arranged so as to project from said outer surface of said neck and which generally traces a portion of a helix; and   a shelf, said shelf being arranged at the top of said outer surface of said neck and extending from said neck, said shelf extending down said neck a distance less than the height of said neck;   wherein, the thickness of said shelf creates a sealing land having a radial thickness greater than the radial thickness of the rest of said container neck.   
     
     
         2 . The device of  claim 1  wherein said shelf extends outward from said neck. 
     
     
         3 . The device of  claim 1  wherein said shelf extends inward from said neck. 
     
     
         4 . The device of  claim 1  wherein said shelf extends both outward and inward from said neck. 
     
     
         5 . The device of  claim 1  wherein said neck is has a radial thickness of about 65 thousandths of an inch. 
     
     
         6 . The device of  claim 5  wherein said shelf has a radial thickness of about 75 thousandths of an inch. 
     
     
         7 . The device of  claim 6  wherein said neck has a height of about 8 tenths of an inch. 
     
     
         8 . The device of  claim 7  wherein said shelf has a height of about 40 thousandths of an inch. 
     
     
         9 . A container, the container comprising:
 a main body including a top section, a middle section, and a bottom section arranged vertically and enclosing an internal volume;   a rim through which material can be placed in said internal volume of said container, said top section of said container interconnecting said rim of said container and said middle section of said container; and   a base, said bottom section of said container interconnecting said base of said container and said middle section of said container; and   a neck, said neck extending from said rim, said neck having an outer surface which is generally circular, and includes a top comprising an edge separated from said top section of said container;   wherein said neck includes at said top, a shelf extending from said neck, said shelf increasing the surface area of said top.   
     
     
         10 . The container of  claim 9  wherein said neck further comprises at least protrusion extending therefrom, said protrusion being sized and shaped to allow for a lid to screwably attached to said neck. 
     
     
         11 . The container of  claim 9  wherein said shelf extends outward from said neck. 
     
     
         12 . The container of  claim 9  wherein said shelf extends inward from said neck. 
     
     
         13 . The container of  claim 9  wherein said shelf extends both outward and inward from said neck. 
     
     
         14 . The container of  claim 9  wherein said neck is has a radial thickness of about 65 thousandths of an inch. 
     
     
         15 . The container of  claim 14  wherein said shelf has a radial thickness of about 75 thousandths of an inch. 
     
     
         16 . The container of  claim 15  wherein said neck has a height of about 8 tenths of an inch. 
     
     
         17 . The container of  claim 16  wherein said shelf has a height of about 40 thousandths of an inch. 
     
     
         18 . The container of  claim 9  further including a metal foil induction sealed to at least a portion of said surface area. 
     
     
         19 . A container, the container comprising:
 a main body including a top section, a middle section, and a bottom section arranged vertically and enclosing an internal volume;   a rim through which material can be placed in said internal volume of said container, said top section of said container interconnecting said rim of said container and said middle section of said container; and   a base, said bottom section of said container interconnecting said base of said container and said middle section of said container;   a neck, said neck extending from said rim, said neck having an outer surface which is generally circular, and includes a top comprising an edge separated from said top section of said container;   means located at said top of said neck for increasing the surface area of said top.
