20080302758 | Container base - A one-piece plastic container includes a body defining a longitudinal axis and having an upper portion, a sidewall portion and a base portion. The base portion defines a plurality of feet extending therearound. The base portion defines a contact diameter ratio of approximately 70-74% and a contact length ratio of approximately 20-23% for a plastic container having a volume capacity of approximately one (1) liter (1000 cc). According to additional features, the one-piece plastic container can have a nub defined on the base portion. For a one-piece plastic container having a volume capacity of approximately one (1) liter (1000 cc), the nub has a diameter of approximately 3-7 mm (0.12-0.28 inch), the base portion defines a contact area ratio of approximately 23-25%, and each foot defines corner transition portions each having a fillet radius of approximately 4-10 mm (0.16-0.39 inch). | 12-11-2008 |
20080314856 | Container thread design - The present disclosure provides a container and a method of making a container. In one example, the container includes a body having an upper portion, a sidewall portion and a base portion. The upper portion includes a blown finish defining a longitudinal axis and an opening into the container. A tamper evident (TE) band is formed on the finish and defines a first diameter at an outermost surface. The TE band defines at least two disconnected radial protrusions. At least one thread is formed on the finish. The at least one thread defines a second diameter at an outermost surface. The first diameter is greater than the second diameter. The TE band defines a gap between each respective disconnected radial protrusion. Each thread defines a thread start portion and a thread run-out portion. A line parallel to the longitudinal axis extends through the thread run-out portion and the gap. | 12-25-2008 |
20110135778 | LIQUID OR HYDRAULIC BLOW MOLDING - 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. | 06-09-2011 |
20120091635 | STRETCH ROD SYSTEM FOR LIQUID OR HYDRAULIC BLOW MOLDING - A mold device and a method related thereto for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity, a stretch initiation rod system for engaging an interior portion of the preform to define a stretch initiation area, and a centrally disposed pressure source positionable within the preform for introducing a pressurized fluid. | 04-19-2012 |
20120207873 | REVERSE STRETCH ROD FOR MACHINE HYGIENE AND PROCESSING - A mold device for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity and a central exterior rod system moveably disposed within the mold cavity. The central exterior rod system is positionable between an extended position engagable with the preform and a retracted position spaced apart from the preform. The central exterior rod system maintains a central orientation of the preform during formation. | 08-16-2012 |
20120299224 | METHOD OF FORMING A CONTAINER - A method of forming a plastic container from a preform. The method comprises injecting a forming liquid into the preform at a predetermined system pressure range, a predetermined flow rate, and a predetermined duration sufficient to create a pressure spike at a peak pressure. The peak pressure being greater than the system pressure to urge the preform into the mold cavity, thus creating enhanced container definition, reduced post mold shrinkage, lower residual material stresses, and/or an improved transfer of the mold geometry and engraving to the final formed container. | 11-29-2012 |
20130161877 | APPARATUS AND METHOD FOR CONTROLLING TEMPERATURE GRADIENT THROUGH WALL THICKNESS OF CONTAINER - A method of forming a container includes providing a preform of the container. The preform has a wall with an interior region and an exterior region. The method also includes disposing the preform in a mold cavity wherein the mold cavity has a mold surface. Furthermore, the method includes introducing a substance into the preform to expand the preform toward the mold surface. The interior region of the wall has a first interior temperature prior to the introduction of the substance and a second interior temperature after the introduction of the substance. The exterior region of the wall has a first exterior temperature prior to the introduction of the substance and a second exterior temperature after the introduction of the substance. The method further includes controlling the first interior temperature to be greater than the first exterior temperature prior to the introduction of the substance. | 06-27-2013 |
20140300035 | USE OF OPTIMIZED PISTON MEMBER FOR GENERATING PEAK LIQUID PRESSURE - Use of optimized piston member for generating peak liquid pressure. A one-step hydraulic blow molding system and method for forming a preform and a liquid filled container from the preform. The machine and method include a sealing mechanism that forms a seal primarily utilizing compressive forces in an axial direction to prevent the leakage of liquid blow medium. The sealing mechanism includes an axial end face of a forming head and an upper axial surface of a neck ring. | 10-09-2014 |
