摘要： A mold for producing a stretch-blow molded polyester bottle from a preform comprises mold parts that can be shifted between an open position and a closed position. The mold comprises: first and second mold shell, within which, in the closed position, a bottle body can be molded; a holding stopper, which can be inserted into a bottle neck; a blow pin having a compressed-air intake for biaxial stretching of the preform; and a bottom part, which closes the two mold shells at the bottom side and is configured to mold the bottle bottom. A base is formed on the bottom part, which base projects into an interior of the mold and has a side wall with an inclination angle (α) of at most 5 degrees with respect to a vertical axis (35) of the mold and is oriented in parallel with the vertical axis.

摘要： A mold body (10) for a blow mold (1). The mold body (10) has a bottom region (14), a shoulder region (13), a central region (15) and a separating plane (12). At least one mold cavity (11) has an inner wall (111) situated in the mold body (10). At least one temperature control channel (30) is arranged in the mold body (10). The at least one temperature control channel (30) is situated and/or positioned in the mold body (10) in such a way as to remove more heat from or supply more heat to a first region (112) of the inner wall (111) than a second region (113) of the inner wall (111) that is adjacent to the first region (112).

摘要： A method for producing a blow molded plastic bottle starting from a preform comprises providing a preform with a specific wall thickness distribution and a blow mold are provided, the cavity of the mold having at least one channel at the locations of the plastic bottle that are to be strengthened. Subsequently, the preform is heated in such a way that the portion of the preform that correlates with the channel of the cavity is thinned to a lesser extent during the stretching and/or blow, and an accumulation of plastics material is brought about in the channel during the main blow molding operation. A plastic container produced by this process has strengthening elements formed as at least one outwardly protruding bead of material and have a wall thickness that is at least 30%, greater than the wall thickness of a portion of the wall adjacent to the bead of material.

摘要： A container closure for a pour opening of a container has a first holding strip with a first and a The first end is connected to a free edge of the screw cap and a second end is connected to a security ring. A second holding strip has a third end connected to the free edge of the screw cap and a fourth end connected to the security ring. The first, second, third and fourth ends are arranged one after the other in the-acircumferential direction on the free edge and on the security ring. A first tongue has a first end and a second tongue has a second tongue end and adjoining the first tongue and is arranged between the second and the third ends. The second tongue is part of the security ring and, in an open position, the first tongue end comes into contact with the second tongue end.

摘要： The invention relates to a preform for producing a plastic container in a 2-stage stretch blow molding method, said preform having a preform body that extends along a central axis and that comprises: a first end a second end that lies opposite the first end, wherein the first end is closed and a neck part with a pouring opening adjoins the second end; and an inner wall that delimits an interior of the preform. Along a length of at least 30 mm of the interior, every point of the inner wall is at a distance of less than 3.5 mm from the central axis. Also disclosed are a suitable method and a device for producing such a preform.

摘要： An injection-molded preform for manufacturing plastic containers, for example plastic bottles, in a stretch blow molding process is disclosed. The preform can have an essentially elongated preform body, whose one longitudinal end is formed closed. On an opposite longitudinal end, the preform body is connected to a neck section that is provided with a pour opening and whose outer wall has a connector to make an interlocking connection with a closure that is equipped with corresponding engagement. The neck section has at least one constriction that extends all the way around and has a wall thickness of between 0.4 mm and 0.8 mm. The injection-molded plastic material exists at least on the at least one constriction in a state that is highly oriented and at least partially crystalline, due to an injection-molding process.

摘要： A preform for a stretch-blow-molded plastic container includes an elongated, tube-like preform body. An outer wall and an inner wall delimit a bottom thickness (b). An outer wall and an inner wall delimit a wall thickness (w). An inner surface and an outer surface (E1) curved in three-dimensionally convex manners are spaced apart such that a distance from their respective apex (S, S′) to the preform body continuously increases. Extensions of the outer wall of the preform bottom along the outer three-dimensionally curved surface (E1), and of the inner wall of the preform bottom along the inner three-dimensionally curved surface (E2) are configured to be interrupted by set-backs area outside of their respective apex (S, S′) thereof.
