Easy open means for bottles and the like

Abstract

This disclosure relates to a bottle cap construction wherein a tear section is defined by score means in the bottle cap construction so that the tear section is initially integral with the remainder of the bottle cap throughout the entire juncture of the tear section with the remainder of the bottle cap. The tear section has at least one edge thereof extending from the top portion of the bottle cap to the free edge of the rim portion that is utilized to crimp the bottle cap to the open end of the bottle, a ring pull tab being secured to the tear section at the top portion of the bottle cap to facilitate the pulling of at least one edge of the tear section from the closure member to open the bottle.

What is claimed is: 
     
       1. In combination, a container having an open end for dispensing product means disposed in said container, and a .[.one-piece.]. closure member secured to said open end of said container to close said open end, said closure member having a top portion disposed over said open end and a depending peripheral rim portion disposed around said container at said open end thereof to secure said closure member to said container, said closure member having a tear section integral therewith throughout the entire juncture of said tear section with the remainder of said closure member and provided with two edges that join together at adjacent ends thereof to define one end of said tear section substantially at the central part of said top portion with at least one edge thereof extending from said top portion to the free edge of said rim portion and with the other edge always .[.progressively.]. diverging away from said one edge from said adjacent ends thereof to the other ends thereof, and a ring pull tab means secured to said tear section at said top portion of said closure member and having a finger-receiving opening passing therethrough to facilitate the pulling of at least said one edge of said tear section from said closure member.
