Abstract
Abstract A tamper evident closure for a container opening including a substantially cylindrical end cap closed at a first end by a top surface, open at a second opposite end and including an annular side wall having a predetermined width extending between the first and second ends, a tamper band member frangibly connected about the second opposite end of the end cap for detaching from the end cap and remaining affixed to the container upon removal of the end cap from the container, an engagement member integrally formed with a first portion of an inside surface of the tamper band for providing gripping contact between the tamper band and a substantially cylindrical or rectilinear neck portion of the container, for restricting axial movement of the tamper band with respect to the end cap and the neck portion and for preventing removal of the tamper band from the container upon severing of the frangible connection and removal of the end cap, and stop members integrally formed with a second portion of, and at a plurality of predetermined positions about, the inside surface of the tamper band for reinforcing the engagement member during contact with the rectilinear neck portion of the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
207 words
A tamper evident closure for a container opening, comprising: a substantially cylindrical end cap closed at a first end by a top surface, open at a second opposite end and including an annular side wall having a predetermined width extending between said first and second ends; tamper band means frangibly connected about said second opposite end of said end cap for detaching from said end cap and remaining affixed to the container upon removal of said end cap from the container; an annular band integrally formed with a first portion of an inside surface of said tamper band means with a substantially serpentine shape for providing gripping contact between said tamper band means and a substantially cylindrical neck portion of the container, for restricting axial movement of said tamper band means with respect to said end cap and said neck portion and for preventing removal of said tamper band means from said container upon severing of said frangible connection and removal of said end cap; and stop means integrally formed with a second portion of, and at a plurality of predetermined positions about, said inside surface of sad tamper band means for reinforcing said annular band during gripping contact with said cylindrical neck portion of the container.
Claim 2
Dependent Claim
207 words
A tamper evident closure for a container opening, comprising: a substantially cylindrical end cap closed at a first end by a top surface, open at a second opposite end and including an annular side wall having a predetermined width extending between said first and second ends; tamper band means frangibly connected about said second opposite end of said end cap for detaching from said end cap and remaining affixed to the container upon removal of said end cap from the container; an annular band integrally formed with a first portion of an inside surface of said tamper band means with a substantially serpentine shape for providing gripping contact between said tamper band means and a substantially cylindrical neck portion of the container, for restricting axial movement of said tamper band means with respect to said end cap and said neck portion and for preventing removal of said tamper band means from said container upon severing of said frangible connection and removal of said end cap; and stop means integrally formed with a second portion of, and at a plurality of predetermined positions about, said inside surface of sad tamper band means for reinforcing said annular band during gripping contact with said cylindrical neck portion of the container.
Claim 3
Dependent Claim
37 words
The closure as defined in claim 1 wherein said stop means include rib means formed on an interior surface of said tamper band means for reinforcing said annular band and preventing removal of said tamper band means.
Claim 4
Dependent Claim
63 words
The closure as defined in claim 1 wherein said stop means include rib means formed on an interior surface of said tamper band means for reinforcing said annular band and providing said substantially serpentine shape to said annular band to effect contract between said annular band and said cylindrical neck portion of said container proximate a position of each of said rib means.
Claim 5
Dependent Claim
19 words
The closure as defined in claim 1 wherein said annular band is pre-formed to provide said substantially serpentine shape.
Claim 6
Dependent Claim
21 words
The closure as defined in claim 1 wherein said annular band is relieved proximate the connection with said tamper band means.
