Abstract
Methods and apparatus for molding a vessel, such as a bottle, with a high quality sealing surface are described herein. In one embodiment, a stepped blow pin can be used to form the sealing surface of a bottle. A stepped blow pin can include a body with a distal end and a proximal end. The blow pin can include a first region that includes a first diameter and a first engagement surface. The blow pin can further include a second region that includes a second diameter. The second region can be positioned between the first region and the distal end. A transition section can be positioned between the first region and second region. The blow pin can also include a top surface position at the proximal end, and a bottom surface positioned at the distal end.

A vessel comprising:
- (i) a bottle comprising:
- an inner chamber for storing materials;
- a neck portion comprising:
- a first opening providing access to the environment surrounding the vessel;
- a second opening providing access to the inner chamber;
- a first region that defines a neck sealing surface, the first region positioned between the first opening and second opening, where the neck sealing surface is smooth and free of defects;
- and
- a second region positioned proximate to the first region;
- and
- (ii) a cap arranged to be secured to the neck portion and including a cap sealing surface, where the cap sealing surface engages the neck sealing surface when the cap is secured to the neck portion.
