Claims
- 1. A tamper indicating closure, comprising:a top wall and annular depending side wall; a tamper indicating band frangibly connected to a lower portion of said depending side wall along an upper portion, thereof wherein said lower portion of said side wall has at least one lip formed there on, said upper portion of said tamper indicating band having at least one lip formed thereon, said at least one lip of said depending side wall facing said at least one lip on said tamper indicating band; an inwardly directed retention mechanism on said tamper indicating band; wherein said at least one lip formed on said depending side wall and said at least one lip formed on said tamper indicating band is an inwardly extending lip on said side wall and an inwardly extending lip on said tamper indicating band and an outwardly extending second lip on said side wall and an outwardly extending second lip on said tamper indicating band.
- 2. The tamper indicating closure of claim 1 wherein said inwardly extending lips and said outwardly extending lips in combination with said annular skirt and said tamper indicating band form first and second opposing facing surfaces which increase the surface contact of opposing surfaces of said upper portion of said tamper indicating band and said lower portion of said annular skirt.
- 3. The tampering indicating closure of claim 2 wherein said closure side wall and said tamper indicating band are connected by a plurality of frangible bridge segments.
- 4. The tampering indicating closure of claim 2 wherein said closure side wall and said tamper indicating band are connected by a plurality of rupturable ribs.
- 5. The tamper indicating closure of claim 4 wherein said tamper indicating band is separated from said side wall by a circumscribing slot, said ribs extending vertically along an inner surface of said side wall and said tamper indicating band.
- 6. The tamper indicating band of claim 2 wherein said first and said second opposing facing surfaces have a first thickness, said annular side wall and said tamper indicating band having a second thickness.
- 7. A closure having a tamper indicating band, comprising:a top wall and depending skirt, said depending skirt having a lower portion; a tamper indicating band frangibly connected to said depending skirt and having an inwardly directed retention mechanism; wherein said lower portion of said skirt and said tamper indicating band have outwardly and inwardly extending lips, said lips and said tamper indicating band and said lips and said skirt forming opposing surfaces, said opposing surfaces having an increased thickness compared to said lower portion of said skirt and said tamper indicating band.
- 8. The closure of claim 7 wherein said opposing surfaces of said tamper indicating band, said skirt and said lips have a first thickness, said first thickness greater than a thickness of said lower portion of said skirt and of said tamper indicating band.
- 9. The closure of claim 8 wherein said thickness of said lower portion of said skirt and said tamper indicating band is a second thickness, said second thickness less than said first thickness.
- 10. The closure of claim 9 wherein said tamper indicating band has a lower section, said lower section having a third thickness, said third thickness greater than said first thickness and said second thickness.
- 11. The closure of claim 9 wherein said skirt and said tamper indicating band are frangibly connected by a plurality of rupturable bridge segments.
- 12. The closure of claim 9 wherein said skirt and said tamper indicating band are separated by a continuous circumferential slot and frangibly connected by a plurality of ribs formed on an interior surface of said skirt and said tamper indicating band.
- 13. A closure with a tamper indicating band, comprising a top wall and depending side wall frangibly connected to a tamper indicating band, said tamper indicating band having an upper portion, said side wall having a lower portion, a first lip and second lip formed on opposed sides of said lower portion of said side wall and a first lip and a second lip formed on opposed sides of said upper portion of said tamper indicating band, a combination of said first lip and second lip and said tamper indicating band and a combination of said first lip and second lip and said side wall each having a same first thickness, said first thickness greater than said lower portion of said side wall and said upper portion of tamper indicating band, said tamper indicating band also having an inwardly directed retention mechanism.
- 14. A closure with a tamper indicating band, comprising:a top wall and depending side wall frangibly connected to a tamper indicating band, said tamper indicating band having an upper portion, said side wall having a lower portion, a first lip and second lip formed on said lower portion of said side wall and a first lip and second lip formed on said upper portion of said tamper indicating band, said first lip on said tamper indicating band and said first lip on said lower portion of said side wall extending inwardly therefrom, said second lip on said tamper indicating band and said second lip on said lower portion of said side wall extending outwardly therefrom, a combination of said first lip and said second lip and said tamper indicating band and a combination of said first lip and said second lip and said side wall having a first thickness, said first thickness greater than said lower portion of said side wall and said upper portion of tamper indicating band, said tamper indicating band also having an inwardly directed retention mechanism.
- 15. The closure of claim 14 further comprising a plurality of vertical ribs formed on an interior surface of said side wall and said tamper indicating band, said vertical ribs frangibly connecting said tamper indicating band to said lower portion of said side wall.
- 16. The closure of claim 15 wherein said tamper indicating band and said lower portion of said side wall are separated by a continuous circumferential groove.
- 17. The closure of claim 14 wherein said retention mechanism on said tamper indicating band is a plurality of inwardly and upwardly directed fingers.
