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

The multi-layer plastic bottle with a handle for holding liquids and the like which includes molds enclosing a hollow parison of molten plastic which is at a blow molding temperature, pinching a portion of the hollow parison as the mold closes to form a hollow moil portion and neck portion, simultaneously pinching a portion of the hollow parison to form a hollow handle portion while leaving a portion of the parison to provide a passage from the moil portion to the handle portion and thereafter expanding the parison through the moil portion to form the container.

Apparatus for making a multi-layer plastic bottle with a handle

The method and apparatus for making a multi-layer plastic container with an integral handle for holding liquids and the like by enclosing a hollow parison of molten plastic which is at a blow molding temperature, pinching a portion of the hollow parison as the mold clses to form a hollow moil portion and neck portion, simultaneously pinching a portion of the hollow parison to form a hollow handle portion while leaving a portion of the parison to provide a passage from the moil poriton to the handle portion and the expanding the parison by supplying gaseous pressure to the moil portion and from the moil portion to form the container from the moil portion through the passage to form the handle.

Method for making a multi-layer plastic container with a handle

In the forming of an article by blow molding parisons into conformity with cavities of an array of mold sections parisons in the form of tubes are extruded from an extruder into an array of neck molds on a head, the head is moved axially away from the extruder to define the parisons, mold sections are closed about the parisons and the parisons are blown outwardly and a take out mechanism grasps and removes the containers after the mold sections are opened. The apparatus for application of labels to the hollow blown plastic articles includes a label carrier mounted for reciprocating movement between the open mold sections and supporting an array of spaced vacuum pick up devices. The carrier is mounted for reciprocating movement past a source of labels exterior to the blow molding mechanism so that labels are picked up by each of the vacuum pick-up devices, and the carrier is moved between the longitudinally spaced array of mold sections, the vacuum devices are actuated to deliver the array of labels to the cavities of the array of open mold sections at the same time as the take out mechanism is moved adjacent the mold sections to grasp the blown containers so that the labels are delivered with substantially no delay in cycle time.

Applying labels to blow molded articles

Apparatus for applying labels to blow molded articles

A blow molding apparatus comprising a wheel plate, a shaft extending horizontally and supporting the wheel plate for rotation and a hub removably mounted on the shaft for rotation with the shaft, and a plurality of sets of molds defining a mold cavity when closed, each set comprising a pair of mold sections, a first mold section of each set being mounted on the hub such that the mold sections are circumferentially spaced about the hub, a second mold section of each set being mounted on the wheel in circumferentially spaced relation and radial alignment with the first mentioned mold section. The second mold sections are mounted on slide assemblies for supporting the second mold sections for movement toward and away from the first mold sections. The hub has circumferentially spaced external surfaces for supporting the first mold sections, the number of surfaces corresponding to the number of first mold sections. The hub may be removed and a second hub replaced on the shaft, having a plurality of circumferentially spaced surfaces, the number of the surfaces of the second hub differing from the number of surfaces of the first hub. The wheel plate accommodates a different number of slide assemblies to correspond with the different number of mold surfaces of the second hub.

Blow molding apparatus

An improved method and apparatus for two-stage blow molding especially suitable for large plastic containers, wherein an overhead shuttle mechanism transfers a blown preform from a preform station to a final blowing station and then to a separation station where the completed article is separated from the upper tail by which it was suspended from the shuttle mechanism during each of the transfer steps. The lower tail is separated from the preform prior to removal from the preform blowing station. An alternative form uses a rotary indexing transfer mechanism, wherein the shape of an upper flash or tail-forming clamp half which is carried by the indexing mechanism creates an interlock with the flash permitting the article to be suspended from and transferred by such single clamp half throughout the operation. The method and apparatus can be utilized to provide a two-stage blow-molded container having integrally formed, threaded bungs by the use of a pair of bung-forming inserts slipped over a pair of upwardly opening blow needles whose center distance is variable by a toggle mechanism. The cylindrical parison is extruded downwardly over the pair of blow nozzles when they are at their minimum spacing, after which they are spread apart to elliptically stretch the parison just prior to closing of the preform mold and blowing. The preform, with the bung forming inserts now captured by the lower pinched portion thereof, is transferred to a final blow mold, where the blow nozzles are inserted through the inserts for final blowing.
