Abstract
A package suitable for storing and dispensing potentially dangerous materials. The package is resistant to opening by children but readily openable by adults, particularly adults having impaired manual dexterity of their hands and/or fingers. The package includes a bottle having a finish portion. The finish portion has a platform with at least one resiliently deformable pushtab secured to the platform. The resiliently deformable pushtabs contain a vertical extensions which engage the interlocking pawls on the innermost surface of the closure skirt when the closure is fully assembled onto the finish portion. To remove the closure, the opposed pushtabs must be depressed prior to unscrewing to the closure to disengage the pushtab extensions from the interlocking pawls on the closure. The package further includes a means for sealing the cap to the finish portion of the bottle when the cap is rotatably secured onto the finish portion so that after the cap is rotatably secured onto the finish portion, the cap can be rotated in a reverse direction without disengaging the pushtab and without unsealing the cap from the finish portion.
