The manufacturing method includes producing a hollow part through a blow molding process, the middle portion of the part concaves inwards; cutting the concave inward part to form two tabletops; and clasping the tabletop on the support bracket.

Device and method for transporting preforms in the region of a blow-molding machine

The invention relates to devices and to methods for transporting preforms in the region of a blow-molding machine, in particular a sorting device (10) for transporting preforms (20) composed of a thermoplastic material in the region of a blow-molding machine for the blow-molding of containers, comprising a transportation wheel (12), which has a plurality of accommodating recesses (18) for accommodating and conveying the preforms (20), which accommodating recesses are arranged on the circumference of the transportation wheel in such a way that the accommodating recesses are distributed in the circumferential direction, a guide collar (16), which extends circumferentially around the transportation wheel (12) in some regions in such a way that the guide collar is radially spaced apart from the transportation wheel, wherein the preforms (20) are transported in suspension between the transportation wheel (12) and the guide collar (16) in the region of the sorting device (10), and a selection unit for selectively removing a respective individual preform (20) transported in one of the accommodating recesses (18) of the transportation wheel (12), wherein the selection unit comprises a pivotable ejecting star (14) with a plurality of ejecting arms (31), which ejecting star, when in the idle position, reaches into the peripheral region of the transportation wheel (12) by means of a first ejecting arm (31) immediately adjacent to the guide collar (16) in the transportation direction of the preforms (20), in such a way that the preforms (20) in the accommodating recesses (18) that are transported past the first ejecting arm (31) are secured against unintentionally falling out, wherein the ejecting star (14), in the event of a rotational motion, pushes an individual preform (20), which is marked for removal, out of one of the accommodating recesses (18) of the transportation wheel (12) by means of a second ejecting arm (32) following after the first ejecting arm (31), and wherein, in a recurring manner after the preform (20) marked for removal has been pushed out, the second ejecting arm (31) takes on the securing of the preforms (20) transported past the second ejecting arm against falling out of the accommodating recesses (18).

Content filling system and verification method of content filling system
12012325 · 2024-06-18 · ·

A preform is sterilized by a preform sterilizer. The preform is blow-molded by a blow-molding device to manufacture a container. Next, the container is filled with a culture medium by a filling device without sterilizing the container by a container sterilizer, and the container is plugged by a plugging device. Thereafter, it is verified how much microorganism survive or propagate in the culture medium in the container. A degree of sterilization in the container sterilizer is adjusted on the basis of a verification result.

PRESSURIZED PLURAL NESTED PREFORM ASSEMBLY AND METHOD OF MANUFACTURE
20190152122 · 2019-05-23 ·

A plural preform assembly having nested preforms with an inner preform and an outer preform. The preforms are sealably joined together, defining a volume between the preforms. Propellant is disposed in the volume between the preforms. The preforms are later blow molded to provide a bag in bottle, bottle in bottle or similar container. The propellant charge is already present when blow molded, preventing the need for a later propellant filling step.

METHOD AND DEVICE FOR MAINTAINING AN INNER DIAMETER OF A PLASTIC CONTAINER

Methods and devices for manufacturing plastic preforms and plastic containers are provided. Methods of manufacturing a plastic preform having an inner undercut include forming a preform of plastic in amorphous state and inserting a plug within the mouth of the preform.
