摘要： Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

摘要： A method for producing filled containers (16) from preforms (13). Each of the preforms is transferred to a circulating molding and filling element (14) of a molding and filling station and is shaped into the respective container in a subsequent molding and filling process in a mold under the effect of pressure from a supplied filler, wherein the mold is designed in multiple parts, including a base mold (21) and mold sides (19, 20), and each container is clamped between the base mold at the bottom and the molding and filling element at the top at least at the end of the molding and filling process. The container is separated from the respective molding and filling element and the respective mold after the molding and filling process. The mold sides are removed from each container before the molding and filling element and the base mold are separated from the container.

摘要： The invention relates to a blow-molded recipient including a reservoir, the reservoir having a bottom wall including an opening, a central element arranged at the opening of the reservoir, and a socket arranged to surround the central element. Both the socket and the central element show a lower end and an upper end and are connected by their respective upper ends by a disc with a central aperture. The assembly includes the socket, the central element and the disc, forming a ring that comes into one piece. At least a part of the bottom wall of the reservoir is arranged to face the disc. The reservoir is irreversibly fixed to the ring.

摘要： Fixation of a container shape of a hollow molded body is not completed during a blow molding process but is completed during an ejection process of an ejection section, thereby shortening an operation time in a stretch blow molding section, and improving the production efficiency of hollow molded bodies by shortening the time required for the blow molding process during a molding cycle.
Cooling air is blown into the inside of the hollow molded body disposed in the ejection section in the ejection process C during the blow molding process B in the next molding cycle to cool the hollow molded body disposed in the ejection section to solidify the container shape.

摘要： 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.
