BOTTLE, INJECTION BLOW MOLDING CORE ROD FOR THE BOTTLE AND RELATED METHOD
A bottle for containing an item, generally a pharmaceutical product, wherein the bottle includes a body having a bottom wall and sidewalls, a neck extending from a top portion of the sidewalls and a thread defined on the neck. The neck defining a mouth of the bottle, an internal surface and an external surface. A neck thickness is defined between the internal surface and the external surface. The thread defines a thread thickness. The thread thickness is substantially the same as the neck thickness.
Free blow bottle design
An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston-like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.
CONTAINER AND METHOD
A blow molded container is provided. The container includes a neck having a neck finish and a transverse rim that defines an opening. A closure is provided that is engageable with the neck such that the rim is movable relative to the neck to define one or more vents configured for passage of a gas. In some embodiments, methods of use and manufacturing containers are disclosed.
Plural blow molding with servo controls
A system for forming a container from a preform includes a first mold having a plurality of first portions that cooperate to define a first internal surface against which the preform is blown for forming a first form. The system also includes a second mold having a plurality of second portions that cooperate to define a second internal surface against which the first form is blown for forming a second form. Also, the system includes a mold servo motor that actuates the plurality of first portions relative to each other and/or actuates the plurality of second portions relative to each other. Furthermore, the system includes a controller that controls the mold servo motor for controlled actuation of the plurality of first portions and/or the plurality of second portions.
Container system and method of manufacture
A plastic, hot-fillable container is provided. The container comprises a blow molded body including a neck and a base having a center portion and a plurality of spaced apart radial segments. At least a portion of each segment is tapered from an outer side to an inner side thereof. Container systems and methods of manufacturing containers are disclosed.
Blow molding method, blow mold, and blow-molded container
A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.
WIDE-NECKED CONTAINER HAVING AN ATTACHED THREADED SLEEVE
A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.
BLOW MOLDING DEVICE, BLOW MOLDING METHOD, AND PREFORM SEALING/POSITIONING PART
A blow molding device of the invention includes a pair of blow cavity split molds (50A, 50B), a chuck member (80) that chucks a mouth portion (20) and conveys a preform (10A), a blow core mold (70) that includes a tubular portion (71) which surrounds circumferences of the mouth portion and a flange (25) and introduces blow air into the preform, and a pair of projecting members (60A, 60B) which have a halved ring shape and are provided detachably on each upper surface of the pair of blow cavity split molds. Each of the pair of projecting members includes an airtight sealing portion (61) which is in contact with a lower end face of the tubular portion of the blow core mold, and a positioning portion (62) which positions the flange of the preform.
PREFORM CONVEYING DEVICE, PREFORM CONVEYING METHOD, AND BLOW MOLDING DEVICE
A preform conveying device (100) of the invention includes a control unit that detects an arriving time at which a conveyor jig arrives at a reference position based on an output of a first encoder, and commands a second motor to move a conveyor arm to a target position at regular intervals from the arriving time. The target position in each command is a position obtained by adding, to a current position of the conveyor jig which is obtained based on a latest output of the first encoder which was obtained when the command has been issued, a moving distance by which the conveyor jig has advanced during a delay time T which spans from a time when the latest output is outputted from the first encoder to a time when the command is received by the second motor.
A THERMOPLASTIC PREFORM FOR A WIDE-MOUTH CONTAINER
An innovative neck (301) configuration is suggested in order to reduce the weight of a large container for beverage dispenser. The neck (301) comprises a neck finish (303) which extends in length (Ltot) starting from the wide mouth (302) of the container to an annular support ring (305) and a smooth surface cylindrical portion (306) which joins the annular support ring (305) to the body (309) of the container. For functional reasons, the total length (Ltot) of the innovative neck (301) remains the same as the usual traditional necks for this type of container, but due to the short length (Ltot) of the neck finish (303) and said cylindrical portion (306), the weight is reduced.
