A one-piece plastic container includes a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion. The upper portion has a spout defining an opening into the container and a finish offset radially outwardly from the spout. A trough defines a passage into the body. The trough slopes toward the passage and defines a non-orthogonal angle relative to the longitudinal axis. According to other features, the sidewall portion is integrally formed with and extends from the upper portion to the base portion. The base portion closes off an end of the container. The finish defines a means, such as at least one thread, for attaching a closure thereon.
