摘要:
The invention relates to a preform (1) for producing plastic containers in a two-stage stretch blow-moulding process, wherein the preform has an elongated preform body (2), the one longitudinal end of which is closed by a bottom (3), while the other longitudinal end adjoins a neck section (4) having threaded sections (5) or similar positive protrusions. The preform (1) is produced from a plastic material suited for the stretch blow-moulding process, said material having a refractive index of 1.3 to 1.6 at a temperature of 100°C to 120°C. The preform bottom (3) is designed such that the outer wall (18) thereof and the inner wall (17) thereof delimit a flat divergent lens. The outer wall (18) and the inner wall (17) of the preform bottom (3) designed as a divergent lens have radii of curvature (c, b) which are greater at least by a factor of 1.4 than the radii of curvature (s, r) of the associated outer wall (8) or inner wall (7) in the region of the preform body.

The invention relates to a combination of a bottle (1) comprising a bottle neck (3) and a snap-on adapter (6) and/or a sealing cap (7) that is/are held on the bottle neck (3). The aim of the invention is to produce a structural shape of great mechanical strength that is easy to assemble. To achieve this, both a snap-on projection (8) and an alignment projection (9) are configured on the bottle neck (3).

The invention relates to a closure (V) for an elastically recovering container (5), with a self-sealing closure unit (V), comprising a membrane (M). According to the invention, a constructionally simple and functionally secure solution may be achieved, whereby the membrane (M) is planar in form before assembly and is clamped in place in the closure (V) along the periphery thereof and thus comprises a displacement (arrow x) in cross-section.
摘要:
An injection-moulded preform for the production of a plastics container in a blow-moulding process is described, which preform has an elongate, tubular preform body (2), which is of closed form at one longitudinal end and which, at its other longitudinal end, has a neck section (4) with a pouring opening (5). The neck section (4) is connected by injection moulding to a closure part (10) which is likewise produced in an injection moulding process. The closure part (10) comprises a flip-top closure (9) and has a section (7) of ring-shaped form with an inner wall (71) which bears directly against an outer surface (61) of the neck section (4) and which fully surrounds a region (6) of closed ring-shaped form of the outer surface (61) of the neck section (4). A plastics container produced from the preform, and a production method for the preform and/or the plastics container, are also described.

P42697PC00 18 Abstract. The invention relates to a plastic container (1) which comprises a container body (2) and a container neck (4) that has a container mouth (5) able to be closed by means of a sealing film. Said container mouth (5) is bordered by a mouth surface (8) which extends circumferentially to form a closed circle and extends inwards from an outer surface (9) of said container neck (3) to a mouth edge (7). On said mouth surface (8), two or more weld ribs (10, 10') are arranged which extend circumferentially in a closed circle, protrude substantially axially out of the mouth surface (8), are radially spaced apart from one another, and are produced by means of a blow-moulding method.
摘要:
Es ist ein supportringloser Kunststoffbehälter (1) beschrieben, der einen Behälterkörper (2) und einen Behälterhals (5) mit einer Ausgiessöffnung (20) aufweist. In Nachbarschaft zur Ausgiessöffnung (20) sind in einer Aussenwandung (6) des Kunststoffbehälters (1) Befestigungsmittel (6) zur formschlüssigen Festlegung eines Verschlusses vorgesehen. In einem Bereich zwischen dem Behälterhals (5) und dem Behälterkörper (2), in einem den Befestigungsmitteln (6) zur formschlüssigen Festlegung eines Verschlussteils nahen Bereich, ist eine umlaufende Ringnut (10) ausgebildet, die in einem Blasverfahren hergestellt ist. Innerhalb der Ringnut (10) ist wenigstens ein Widerlager (16) zur Drehmomentaufnahme ausgebildet.
摘要:
The invention relates to a wide-neck plastic container (1) produced using extrusion blow moulding and having a closure cap (4) that can be non-detachably connected to a container neck (3) of the wide-neck plastic container (1), said container neck having a container opening (30). A number of locking projections (32), that are hollow as a result of the manufacturing method, are arranged on an outer wall (31) of the container neck (3), said projections being distributed over a periphery of the container neck (3) and projecting from the outer wall (31) of the container neck (3). An inner wall of the casing of the closure cap (4) is provided with corresponding locking recesses (52). In the case of the closure cap (4) mounted on the container neck (3), the interlocked locking elements (32, 52) are inaccessibly covered by a section of the casing (41) of the closure cap (4).
摘要:
A preform (1) for the production of biaxially extended plastic bottles has a rigid, substantially elongated body (2), which at one longitudinal end thereof comprises a base (3) and the opposite longitudinal end of which is configured as a neck section (4) provided with a pouring opening (5). The preform (1) has outer and inner walls (A, I), which extend at least across a partial region of the axial length thereof and are formed by separate plastic layers. At least one intermediate layer (Z) is embedded in at least a partial region of the body (2) in a space delimited by the outer and inner walls (A, I) of the body (2), the intermediate layer extending across part of the axial length and the circumference of the body (2) and having a color that deviates from the outer or inner layers (A, I).
