Abstract
Abstract This relates to an easy opening container wherein a displaceable panel portion is defined by a line of weakness and has attached thereto an opening device. Most particularly, the opening device is formed of a length of flexible material, such as a tape, which is folded upon itself and has a lower leg bonded to the displaceable panel portion. The outer leg, which functions as a pull element, has secured thereto an opening element which extends beyond the fold and has a nose for effecting an axially inwardly directed opening force on the displaceable panel portion.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An easy opening container component comprising a panel, a line of weakness in said panel defining a displaceable panel portion, and an opening device, said opening device including a pull member, said pull member being reversely folded and including first and second portions integrally connected along a transverse hinge line, said first portion overlying said displaceable panel portion and being permanently secured thereto with said hinge line being in spaced adjacent relation to an adjoining portion of said line of weakness, said second portion generally overlying said first portion and including a grip part remote from said hinge line, and an opening element permanently secured to said second portion adjacent said hinge line and projecting beyond said hinge line, said opening element terminating in a force applying end generally aligned with said line of weakness adjoining portion.
Claim 2
Dependent Claim
137 words
An easy opening container component comprising a panel, a line of weakness in said panel defining a displaceable panel portion, and an opening device, said opening device including a pull member, said pull member being reversely folded and including first and second portions integrally connected along a transverse hinge line, said first portion overlying said displaceable panel portion and being permanently secured thereto with said hinge line being in spaced adjacent relation to an adjoining portion of said line of weakness, said second portion generally overlying said first portion and including a grip part remote from said hinge line, and an opening element permanently secured to said second portion adjacent said hinge line and projecting beyond said hinge line, said opening element terminating in a force applying end generally aligned with said line of weakness adjoining portion.
Claim 3
Dependent Claim
47 words
A container component according to claim 1 wherein said line of weakness is a continuous line, said displaceable panel portion is removable from said panel, and said first portion extends beyond said displaceable panel portion and is permanently secured to said panel adjacent said displaceable panel portion.
Claim 4
Dependent Claim
27 words
A container component according to claim 1 wherein said pull member is formed of a flexible material and said opening element is formed of a rigid material.
Claim 5
Dependent Claim
18 words
A container component according to claim 3 wherein said pull member is in the form of a tape.
Claim 6
Dependent Claim
18 words
A container component according to claim 1 wherein said pull member is in the form of a tape.
Claim 7
Dependent Claim
32 words
A container component according to claim 1 wherein said pull member is in the form of a tape, and is secured to said opening element and said displaceable panel portion by bonding.
Claim 8
Independent Claim
96 words
A method of displacing a panel portion defined in a panel by a line of weakness, said method comprising the steps of providing a flexible member, securing the flexible member to said displaceable panel portion and to an opening element, pulling on said flexible member to first force the opening element against the displaceable panel portion to initiate rupture of the panel along the line of weakness, and then further pulling on the flexible member to continue rupture of the panel along the line of weakness and to withdraw the removable panel portion from the panel.
Claim 9
Independent Claim
96 words
A method of displacing a panel portion defined in a panel by a line of weakness, said method comprising the steps of providing a flexible member, securing the flexible member to said displaceable panel portion and to an opening element, pulling on said flexible member to first force the opening element against the displaceable panel portion to initiate rupture of the panel along the line of weakness, and then further pulling on the flexible member to continue rupture of the panel along the line of weakness and to withdraw the removable panel portion from the panel.
