Abstract
A plastic perforative spout for dispensing substances through a sidewall of a plastic container includes a unitary rigid plastic, preferably teflon or polyethylene, perforation element with a protective cap, a dispensing valve removably attached to the perforation element, and an accessory circular adaptor for rounded containers. The plastic cutting element extends from a hollow shank surrounding an opening in a flange portion of a hollow tubular body. Two intersecting cross ribs are formed inside the shank, and a vertical rib extends from the intersection of the cross-ribs to the point of the radius cut semi-circular cutting element. The plastic dispenser is removably attached over the tubular body, and a boss is pressed to displace the flexible concave valve to dispense the container contents through the mouth of the dispenser. A snap lock holds the valve open if desired. The circular adaptor fits over the shank and defines a concave surface for mounting flush against a curved surface. Options include swaged metallic blades and metallic plating for the plastic blades.
