Abstract:
A method of inspecting a blow molded container having a finish, a base, a body between the finish and base, and etching at the base. The method includes identifying where on the base the etching is located, designating the base as accurately blow molded if the etching is located at a predetermined location of the base, and designating the base as not accurately blow molded if the etching is not located at the predetermined location of the base.
Abstract:
A controlled release container including a base. The base has a flexible diaphragm movable between a relaxed position and a depressed position. In the depressed position the flexible diaphragm reduces an interior volume of the container to dispense a dosage amount of material stored within the container. The dosage amount directly corresponds to an internal volume of the container displaced by moving the flexible diaphragm to the depressed position.
Abstract:
A system for forming a container from a preform, wherein the preform has a finish and a support ring. The system includes a mold having a mold cavity defining an internal surface and adapted to accept the preform, a pressure system having an inlet and an outlet outputting fluid, a blow nozzle receiving the fluid from the pressure system and introducing the fluid at a pressure into the preform thereby expanding the preform toward the internal surface of the mold cavity and creating a resultant container. The system further includes a first seal engagement selectively engageable between the blow nozzle and the finish of the preform and a second seal engagement selectively engageable between the blow nozzle and an adjacent feature.
Abstract:
An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold having a mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is operable to draw liquid through the inlet and urge it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. A pressure compensation system can exert a clamping force on the mold in response to the pressure source. The liquid remains within the container as an end product.
Abstract:
A preform for use in a system for simultaneously forming and filling a container. The preform includes a finish region, a stretch initiation region adjacent to and descending from the finish region, a transition region adjacent to and descending from the stretch initiation region, a body region adjacent to and descending from the transition region, and an end cap region enclosing an end of the body region to define an interior for receiving a forming fluid. The stretch initiation region defines a wall thickness less than a wall thickness of the body region to encourage initial localized stretching in response to the forming fluid prior to stretching within the transition region or body region.
Abstract:
A mold device for forming a plastic container from a preform. The preform includes at least one exterior feature formed thereon. The mold device comprises a mold defining a mold cavity, and a central exterior rod being movable within the mold cavity. The central exterior rod includes a locating feature formed therewith that is engagable with the at least one exterior feature of the preform for maintaining a central orientation of the preform within the mold cavity during forming.
Abstract:
An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is a servo motor system that includes an inlet. The servo motor system is operable to draw liquid through the inlet and urged it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. The liquid remains within the container as an end product.
Abstract:
An apparatus for forming a container comprising a housing and a rod apparatus disposed in the housing. The rod apparatus includes a rod for at least partially forming a container preform. The apparatus further includes a nozzle system disposed in the housing that is operably coupled with the rod apparatus. The nozzle system is positionable between a first position preventing pressurized fluid from being injected into the container preform and a second position permitting pressurized fluid to be injected into the container preform.
Abstract:
A blow-molded plastic container comprising a base portion having a flexible standing ring radially extending therefrom. The flexible standing ring is disposed about a lowest most portion of the container and operable to support the container on a surface. The flexible standing ring defines an annular groove thereabout that collapses in response to internal vacuum forces and/or external loading forces. The container further comprises a body portion that extends from an upper portion to the base, such that the upper portion, the body portion and the base cooperate to define a receptacle chamber within the container into which product can be filled.
