A mold system for blow molding hollow plastic containers includes an extruder for providing a hollow tube of plastic material having a longitudinal axis. Three mold segments include at least two mold segments that are movable against the third mold segment, in directions perpendicular to the tube axis, between a closed position in which the mold segments form a hollow mold cavity in which the tube is captured and an open position spaced from the tube axis. A blow pin is disposed on one of the mold segments to pierce the tube in the closed position of the mold segments. One of the mold segments may be a mold core movably mounted on a second of the mold segments, and cylinders are mounted on the second mold segment for moving the mold core between an extended position and a retracted position with respect to the second mold segment. The blow pin may be movably mounted on the mold core.

Method and apparatus for blow molding hollow plastic containers

A container assembly that includes a container having a body with a cylindrical neck and an integral lug projecting radially inwardly from the neck. A fitment has a cylindrical wall adapted to be received within the container neck. The fitment wall has internal threads for receiving a container cap, and an axial slot adapted to be received by snap fit over the lug in the container neck. The neck lug thus cooperates with the slot in the fitment wall for both retaining the fitment axially within the neck, and preventing circumferential rotation of the fitment within the neck. The fitment and cap are provided to a packager as a subassembly separate from the container. The container is rapidly filled with product through the relatively large opening in the container neck, and the cap/fitment subassembly is then snapped into the container neck to complete the package assembly.

Dispensing package and method of use

Wheel molding apparatus for molding thermoplastic containers or other articles, the apparatus having a multiplicity of sets (,) of opposed, separable radially aligned mold halves (,) that travel in a circular path about a horizontal axis. The inner of the mold halves (14) is separated from the outer of the mold halves (,) at the 12:00 o'clock position of the mold set that includes such mold halves to permit the molded article to be ejected from the mold set. However, the ejection of the molded article should not take place until after the separation of the mold halves, and this requires that the molded article be positively retained within the outer mold half until it is desired to eject the article therefrom. This is accomplished by translation of a translatable pin (,) within a passage (,) of the outer mold half, the translatable pin having an undercut (,) near an end thereof that extends into the article, and preferably into a portion of excess material thereof, and forms an interference fit with the article at an outermost position of the translatable pin, to which the pin is resiliently biased by a spring (,). Ejection of the article is obtained by engaging an exterior free end of the pin by a cam (,) to move the pin against the biasing effect of the spring to a second position at which there will be no interfering relationship between the pin and the article and the pin will then positively eject the article from the outer mold half.

Method and apparatus for the manufacture of blown plastic containers

A combined drain back spout (DBS) fitment and plastic container assembly comprising a plastic container body and finish and a plastic drain back spout fitment having a pour spout connected to a surrounding drain gutter and spill-catching apron. The fitment apron has an integral mounting collar with a radial flange spanning the finish end edge and a collar skirt dependent therefrom and encircling the outer surface of the container finish and being sealably joined thereto by a spin weld joint. The lower free end edge of collar skirt is closely spaced from the juxtaposed surface of the container body, and the collar skirt and finish exterior surface conjointly define an intervening space for receiving, containing and hiding spin weld slag and/or shavings. The finish is corrugated to provide annular external ribs and intervening external grooves to thereby provide sacrificial parent spin weld material in the rib crowns and slag-receiving spaces in the grooves.
