A substantially cylindrical plastic parison is expanded within a blow mold against the internal walls thereof to form a plastic drinking vessel with a rim having substantially smooth inner and outer surfaces thereon. The inner surface is formed by a reciprocating cutter head assembly including an annular cutter blade with an outside diameter slightly less than the inside diameter of wall surfaces of the blow mold adjacent to a peripheral recess in the blow mold in which an external bead on the rim is formed. The cutter blade and cutter head assembly form a dome-shaped top in response to expansion of the parison. When the cutter blade is retracted axially from the blow mold the dome-shaped top is severed from the vessel. In an alternative embodiment the vessel and a partially severed dome-shaped top are removed as an integral unit from the blow mold and the dome-shaped top is then completely severed from the vessel utilizing a rotary cutter blade.

Method and apparatus for blow molding a plastic drinking vessel

A disposable and recyclable plastic container for use in a post-mix beverage dispensing system includes first and second openings at a top end thereof. The container may be filled with syrup through the first opening and withdrawn by a pump through the second opening. The second opening is defined by an upper end of a tube, which is integrally formed with the container by blow-molding. The tube extends from the top end of the container, down the exterior of the container sidewall and through the bottom. As syrup is withdrawn, the first opening, or an associated vent, vents the container to assist in the withdrawal of syrup. The second opening and tube have a valve actuator therein for a spring-loaded valve in a conventional quick-disconnect coupling such as used in bag-in-box type systems. The top and bottom of the container have complementary shapes to permit vertical nesting and stacking of plural like containers, and sidewalls of the container are concave to prevent bulging of the sidewalls when containers are filled.

A disposable container for use as a syrup package in a post-mix beverage dispenser comprising a base end and a discharge end opposite thereto, sidewalls extending from the base end towards the discharge end, and a neck connecting the sidewalls to the discharge end and defining a discharge opening through which syrup or flavor concentrate may be dispensed. A flow-rate control tube having an openable, sealed end and a closed end is integrally formed with the container sidewalls. The flow-rate control tube has the openable, sealed end positioned in the container base end and has a major portion which extends substantially longitudinally of the container on the outside of the sidewalls, to an associated minor portion of the tube, which extends through the neck of the container so that the open end of the tube is in communication with the interior of the container in the neck region.
