Abstract
A bottle cap (10) having a top (12) and a downwardly depending skirt (14). Skirt (14) includes an angled upper portion (20) and a generally cylindrical lower portion (22) with an exterior bead (24) thereon. Angled upper skirt portion (20) extends from a perimeter bead (23) down to a locking bead (34), which allows upper skirt (20) to transfer an application force from perimeter bead (23) radially to locking bead (34) in order to push the locking bead down around the upper crown (42) of a bottle neck (40). A method of applying the bottle cap is also disclosed.
Claims12
A closure for a container of the type having a rounded neck with an upper crown defining a neck opening, comprising:
- a top for closing off the neck opening;
- a skirt depending from the top for covering upper side portions of the neck;
- a locking bead extending inwardly from and interior side of the skirt at a location spaced from the top, the locking bead adapted to mount underneath the upper crown upon full mounting of the closure on the neck;
- and
- a cylindrical lower portion of the skirt extending below the locking bead;
- wherein the upper portion of the skirt from the locking bead to the top is angled inwardly, to direct at least a portion of the application force radially outwardly to assist the locking bead in clearing the upper crown, and
- wherein the skirt includes a pair of tear lines that extend up into the upper portion of the skirt, and
- wherein the closure includes a non-spill central opening and a removable plug.
