Abstract
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.
Claims33
A one-piece plastic container comprising:
- a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion, said upper portion having a spout defining an opening into the container and a finish offset radially outwardly from said spout, wherein a trough is formed at a transition between said finish and said spout, said trough defining a passage into said body.
A one-piece plastic container comprising:
- an upper portion comprising:
- a spout defining an opening into the container;
- and
- a finish offset radially outwardly from said spout;
- wherein a trough is formed at a transition between said finish and said spout, said trough defining a passage into said body;
- a shoulder region integrally formed with and extending from said upper portion;
- and
- a sidewall portion defining a longitudinal axis and extending from said shoulder region to a base portion, said base portion closing off an end of the container and defining a first plane;
- wherein said opening defines a second plane that is generally parallel to said first plane.
A preform adapted to be molded into a plastic container, the preform comprising:
- a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion, said upper portion having a spout defining an opening into said preform and a finish offset radially outwardly from said spout, wherein a trough is formed at a transition between said finish and said spout, said trough defining a passage into said body.
A method of making a blow-molded plastic container comprising:
- disposing a preform into a mold cavity, said preform defining a longitudinal axis and an injection molded upper portion having a spout defining an opening into said preform and a finish offset radially outwardly from said spout, wherein a trough is formed at a transition between said finish and said spout, said trough defining a passage into said preform;
- and
- blowing said preform against a mold surface of the mold cavity to form a sidewall portion integrally formed with and extending from said finish and a base portion, said base portion closing off an end of the container.
