Abstract
Abstract A child-resistant closure includes a tamper-proof band which engages an associated container finish, and which must be separated from the remainder of the closure for removal of the closure from the finish. A pull tab and weakening grooves are provided to permit manual separation of the tamper-proof band from the remainder of the closure. A resilient shield integrally formed with the tamper-proof band overlies the pull tab and normally prevents grasping thereof. Removal of the closure is possible only when the shield is manually deflected and held in position while the pull tab is grasped and the tamper-proof band torn away from the remainder of the closure.

Claim 1
Independent Claim
104 words
A child-resistant, tamper-proof closure comprising a panel section; an annular skirt depending from the periphery of said panel, the lower portion of said skirt including a tamper-proof band removably attached to the remainder of said skirt; means on said tamper-proof band for engaging the finish of an associated container to prevent removal of the closure while the tamper-proof band is attached to the remainder of the closure, grasping means on said skirt to facilitate removal of said tamper-proof band; and shield means integrally formed with said closure for normally preventing access to said grasping means, said shield means being manipulable to permit such access.
Claim 2
Dependent Claim
104 words
A child-resistant, tamper-proof closure comprising a panel section; an annular skirt depending from the periphery of said panel, the lower portion of said skirt including a tamper-proof band removably attached to the remainder of said skirt; means on said tamper-proof band for engaging the finish of an associated container to prevent removal of the closure while the tamper-proof band is attached to the remainder of the closure, grasping means on said skirt to facilitate removal of said tamper-proof band; and shield means integrally formed with said closure for normally preventing access to said grasping means, said shield means being manipulable to permit such access.
Claim 3
Dependent Claim
20 words
The closure defined in claim 1 wherein said grasping means includes a pull tab outwardly projecting from said tamper-proof band.
Claim 4
Dependent Claim
35 words
The closure as defined in claim 1 or 2 wherein said shield means comprises a resilient flap overlying said grasping means to prevent grasping thereof, said flap being manually deformable to expose said grasping means.
