Bottle opener

Claim 2

In combination, a plastic bottle having a neck portion, an annular groove in said neck portion concentric to the central axis of said bottle, an end closure which is integrally formed with said neck portion and is concentric to the central axis of said bottle, and a bottle opener for severing said end closure to provide an opening into said bottle through which a product therein can be dispensed, said bottle opener comprising a neck ring having an opening therein of a diameter to permit said neck ring to be urged over and disposed about said end closure to engage said opener within said annular groove, the interior diameter of said opening forming a cutting edge for severing said end closure from said bottle, and means integrally formed with said neck ring for manipulating said opener while said bottle is held vertically upright to engage said cutting edge in said neck ring to sever said end closure from said bottle.

Claim 3

The combination of claim 1, wherein said bottle opener comprises a flat, elongated length of material having in one end thereof an opening forming said neck ring and in the other end thereof another opening forming a finger ring, the interior diameter of said opening forming said finger ring being such as to permit a finger to be extended through it for manipulating said bottle opener while said bottle is held vertically upright to engage said cutting edge in said neck ring to sever said end closure from said bottle.

Claim 4

The combination of claim 2, wherein the interior diameter of said neck ring is circular-shaped.

Claim 5

The combination of claim 1, wherein said neck ring is oval-shape having a major diameter substantially corresponding to the diameter of said end closure and a minor diameter slightly smaller than the diameter of said end closure, whereby said opener upon being rotated while said bottle is held stationary will sever said end closure therefrom.

Claim 6

The combination of claim 1, wherein said bottle opener comprises a neck ring including two substantially circular-shaped neck ring members which are slidably and rotatably affixed together atop one another, each of said neck ring members having an oval-shaped opeNing therein of a major diameter substantially corresponding to the diameter of said end closure and a minor diameter slightly smaller than the diameter of said end closure, whereby each of said neck ring members upon being rotated while said bottle is held stationary will sever said end closure from said bottle, said means integrally formed with said neck ring for operating said opener comprising at least one wing integrally formed with each of said neck ring members and disposed upright substantially perpendicular to said neck ring members so as to provide a pair of finger grips for rotating said neck ring members, said wings when angularly rotated towards one another causing said neck ring members to be rotated in opposite directions so that the cutting edges thereof function as a double cutting edge to sever said end closure from said bottle.

Claim 7

In combination with a plastic bottle having an end closure integrally formed thereon, a bottle opener for severing said end closure to provide an opening into said bottle through which a product can be dispensed, said bottle opener being generally cylindrical shaped and having a body portion adapted to be affixed to said bottle to reclose it, one end of said body portion being folded inwardly so as to form a flange defining a neck ring having an opening therein of a diameter to permit said neck ring to be urged over and disposed about said end closure, a locking flange interior of said body portion cooperating with said neck ring to retain the severed end closure within said opener, said opening in said neck ring being oval-shaped with a major diameter substantially corresponding to the diameter of said end closure and a minor diameter slightly smaller than the diameter of said end closure, whereby said opener upon being rotated while said bottle is held stationary will sever said end closure from said bottle, said opener being inverted and affixed to said bottle to reclose it after said end closure is severed from said bottle, said end closure engaging the severed edge on said bottle and forming a seal therewith.

Claim 8

In combination with a plastic bottle having an end closure integrally formed thereon, a bottle opener for severing said end closure to provide an opening into said bottle through which a product can be dispensed, said bottle opener being generally cylindrical shaped and having a body portion adapted to be affixed to said bottle to reclose it, one end of said body portion being folded inwardly so as to form a flange defining a neck ring having an opening therein of a diameter to permit said neck ring to be urged over and disposed about said end closure, a locking flange interior of said body portion cooperating with said neck ring to retain the severed end closure within said opener, said opening in said neck ring being oval-shaped with a major diameter substantially corresponding to the diameter of said end closure and a minor diameter slightly smaller than the diameter of said end closure, whereby said opener upon being rotated while said bottle is held stationary will sever said end closure from said bottle, said opener being inverted and affixed to said bottle to reclose it after said end closure is severed from said bottle, said end closure engaging the severed edge on said bottle and forming a seal therewith.
