Abstract: A relatively large water bottle is blow molded from thermoplastic material and includes a generally cylindrical body, a generally frustoconical top breast at the upper end of the body, and a filling and dispensing neck extending upwardly from the central portion of the top breast. Angularly spaced reinforcing ribs are formed on the inner side of the top breast to increase the column strength thereof. The ribs are formed as an incident to blow molding the bottle from a preform having angularly spaced external ribs on a frustoconical portion of the preform, the external ribs being converted into internal ribs during the blow molding operation.

Abstract: A preform injection molded from PET includes a frustoconical section whose outer surface is formed with a series of angularly spaced ribs. When the preform is converted into a bottle by a blow molding operation, the frustoconical section of the preform is converted to a frustoconical top breast for the bottle while the external ribs of the preform are converted into internal ribs which are spaced angularly around the inner side of the top breast to increase the column strength thereof.

Abstract: A tap for use with a container closure of the type having a pair of resilient sealing plugs. The tap includes a body which supports spaced product and gas tubes adapted to be thrust through the resilient sealing plugs of the closure. When the tap is removed from the container, the gas tube separates from the tap body and remains in the respective sealing plug so as to vent pressure in the container safely to atmosphere. Stabilizing fins extend downwardly from the tap body and engage the top of the closure to help hold the tap in a secure vertical position on the container.

Abstract: A tap for a beer keg having a Sankey-type fitting with radially inwardly extending lugs which normally are used to hold a conventional tap in a locked position on the keg. To prevent the locking lugs of the fitting from being damaged or to permit use of the keg after the lugs have become worn or damaged, the present tap includes a radially expandable and contractible collar adapted to lock onto the external lip of the fitting. The collar is formed by two camming clamps connected to swing about a hinge and adapted to float angularly relative to the body of the tap in order to permit the clamps to center themselves on the fitting. As the clamps are closed, they cam against the external lip of the fitting and force the tap downwardly to open the valves of the fitting.
