Abstract: A cartridge for use in conjunction with a container to dispense a liquid in the cartridge into the container. The cartridge is comprised of a hollow body defined by an enclosing wall that has a closure at an upper end and a lower cartridge wall that is integral to the hollow body, but of a thickness less than that of the hollow body enclosing wall. The lower cartridge wall of a reduced thickness is in a narrowed section of the hollow body. A closure is sealed onto an upper part of the hollow body and has a funnel-like shape with a lower funnel wall. The funnel wall is of a reduced thickness as compared to the remainder of the closure. A flange on the hollow body rests on a container upper surface to support the cartridge on the container. A container closure will hold the cartridge in place during use. A dispensing pump on the container closure has a dip tube which pierces the funnel wall and cartridge wall and thereby dispense the cartridge contents into the container.

Abstract: A dripless closure assembly for a container comprising a body seated in the neck of the container and which has a pouring spout. A measuring cup which also functions as a cap is disposed over the pouring spout and has a first threaded outwardly disposed skirt for threaded engagement with the neck of the container. A second skirt inward of the outer skirt and extending into the body is provided for eliminating dripping on the threads.
