Abstract: The leaching chamber endplate including snap connectors, pipe stops, pipe scores, drill guide(s), and a barrier that facilitates enhanced engagement between the endplate and leaching chamber. This endplate is preferably formed using a blow molding process that forms, in situ, the endplate, including the snap connectors and the barrier.

Abstract: A one-piece soft plastic bottle includes a generally cylindrical bottom portion and a tapered upper portion having a flexible tapered bellows at an upper end thereof. A short tapered top tapers outwardly and upwardly from the tapered bellows and includes a top end with a small aperture therein. A closure for the central aperture extends above the top end and is broken away by the user to expose the central aperture. The closure includes a cylindrical extension and large wings extending laterally and downwardly therefrom. Extending from the cylindrical extension is a filling tube which is crimped after filling to close the filling tube.

Abstract: A dual wheel caster assembly consisting of an arcuate central horn carrying an axle with projections on either side of the horn that rotatably receive wheels. The axle has recesses that receive annular projections on the wheels for the purpose of retaining the wheels in position.A vertical opening in the horn receives a vertical pintle having a portion projecting upwardly from the horn adapted to be received in an associated piece of furniture. This pintle has two spaced thrust surfaces, a lower one adapted to directly engage the plastic horn and the other one adapted to engage a one piece plastic bearing.The two thrust surfaces are spaced such that the lower thrust surface initially carries most of the load until a certain amount of wear causes the load to be distributed between the two thrust surfaces from the associated piece of furniture.
