ABSTRACT:
A resealable closure assembly for a container with integral closing/opening and resealing structure. The resealable closure assembly has a neck portion that is wider at its bottom than at its top. The shape of the neck portion is generally conical or frusto-conical. At least one dispensing aperture is formed in the upper area of the neck portion. A laterally extending fold line is formed in the neck portion spaced downwardly from its top end and any dispensing apertures therein. The top of the neck portion is foldable downwardly about the fold line in order to seal off the dispensing apertures in the upper area of the neck portion. Protrusions are formed integrally on the outer surface of the neck portion for detachably securing the top end of the neck portion against the area of the neck portion located below the fold line. The closure assembly is generally made of a flexible material such as plastic. The closure assembly may have a bottom wall attached to its lower end, it may have a tubular member attached to its lower end internally threaded, or it may have a tubular member that forms part of a container attached to its bottom end.
