Stretch-blow molded plastic container and stretch-blow-molding method
A stretch-blow molded plastic container includes a container body. A container neck, adjoins the container body via a shoulder region and has a container opening. The container body and the container neck are mutually separated by a support ring, which substantially radially protrudes, runs circumferentially in at least some regions and which has a support ring underside. The shoulder region has a first shoulder section, which runs in immediate proximity to the support ring underside, and a second shoulder support, which is integrally connected to the first shoulder support and which substantially radially adjoins the support ring. In a stretch-blow molding method a support ring of a preform, which is placed into a mold cavity of a blow molding tool, is overblown during radial and axial stretching of the preform.
Synchronous running safeguard for transfer stations for devices for handling containers, and a device and a method for blow-molding containers
A synchronous running safeguard for transfer stations or devices for handling containers, in particular for handling bottle-like containers made of glass or plastic, having a first and a second rotary element, which each have holding elements for the containers and each have a motor drive. The rotary elements are disposed in relation to one another such that the containers can be transferred in a transfer area from one of the first holding elements to one of the second holding elements. The rotary elements, each rotationally connected, have a control element having engagement elements, and the control elements are in meshing engagement with one another. The control elements are disposed in such a way that, during operation the control elements are interengaged without contact during the rotary movement of the rotary elements and that, in the event of a fault, the control elements are interengaged with contact.
MOLDING SYSTEM, APPARATUS FOR TAKING OUT MOLDED PRODUCT, MOLD EQUIPMENT, AND METHOD FOR MANUFACTURING HOLLOW MOLDED PRODUCT
An apparatus for taking out molded product in a molding system has an insert portion, abutting portion, recess, and suction port. The insert portion is inserted in a hollow molded product via an opening portion serving as a blow pin extraction port of the hollow molded product. The abutting portion is arranged at the circumference of the insert portion and abuts on an outer circumferential surface of the hollow molded product spaced a predetermined distance from the opening portion serving as the blow pin extraction port. The recess is provided between the insert portion and the abutting portion, accommodates the opening portion in the state where the outer circumferential surface of the hollow molded product abuts on the abutting portion, and forms a stretch of closed space to the inside of the hollow molded product. The suction port is provided in the insert portion and sucks an ambient atmosphere.
BLOW MOLDING MECHANISM, INTERMEDIATE MOLD, AND MOLD UNIT
A blow molding mechanism includes a split mold that forms a part of a mold used in blow molding with respect to an intermediate molding product, performs mold closing before the blow molding starts, and performs mold opening after the blow molding is completed; a first bottom portion mold that forms a part of the mold, and molds at least a part of a bottom portion of the intermediate molding product on a side opposite to a mouth portion; and a suction unit that starts suction of at least a part of the bottom portion of a final molding product after the mold opening is performed and before the final molding product is separated from the first bottom portion mold, at the same time as the split mold performs the mold opening, or before the split mold performs the mold opening, after the blow molding is completed.
APPARATUS AND METHOD FOR PRODUCING PLASTICS MATERIAL PREFORMS WITH SPECTRAL ANALYSIS DEVICE
An apparatus for producing plastics material containers has a production device having a plurality of production units for producing plastics material preforms, a forming device having a plurality of forming stations for forming the plastics material preforms into the plastics material containers and a transport device for transporting the plastics material preforms produced by the production device to the forming device. The apparatus has a spectral analysis device for inspecting and/or analyzing at least one area of the plastics material preforms produced by the production device, arranged between the production device and the forming device. The spectral analysis device is configured for spectral analysis of the radiation impinging thereon.
Cooling mold, and apparatus and method for manufacturing resin molded article
A cooling mold for cooling a resin preform that has a gate portion protruding outward from a center of a bottom portion, in which an accommodating space that accommodates the preform is formed in the cooling mold, a bottom region facing the bottom portion of the preform in the accommodating space has a shape following the bottom portion of the preform, and an air sucking hole for sucking air is formed in the bottom region at a position shifted from the center of the bottom portion of the preform. In the accommodating space, a region facing a body portion of the perform and a bottom region facing the bottom portion of the perform are formed as a single member.
BLOW MOLDING MECHANISM
A blow molding mechanism molds a final molding product by blowing a gas into an intermediate molding product held by a mold, the blow molding mechanism includes: a suction circuit that suctions the final molding product to attach the final molding product to the mold; and a suppression unit that suppresses a pressure in the suction circuit to a predetermined value or lower.
Method for producing a container product and device for implementing the method
A method for producing at least one molded, filled and sealed container product (10) includes at least the method steps of: extruding a hose (32) by an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; cutting the parison (22) to length; transporting the cut parison by a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps.
