The invention further relates to a method for producing a container from several segments and a container comprising a closed barrier layer. The disclosed container is composed of at least two segments (22a, 24) which are joined together circumferentially at the edges of the faces thereof by means of one respective welded connection (16, 17) such that an enclosed space is formed. An inner pressure that is different from the ambient pressure is applied within the enclosed space while a change in pressure is monitored.

Abstract: The invention relates to a device for the production of multi-layer, co-extruded, tubular pre-forms made from thermoplastic plastic. A co-extrusion head (10) comprises co-axially arranged flow channels (FK1, FK2), each supplied by a single inlet opening (ZF1, ZF2) with a material melt, distributed annularly in a distribution ring (26, 28). The gap width in each distribution ring (26, 28) is greater in the vicinity of the inlet opening (ZF1, ZF2) than the gap width (s2, s6) in the region of the side opposing the inlet opening (ZF1, ZF2). The flow channels (FK1, FK2) are also asymmetric with regard to the gap widths.

Abstract: What is described is a plastic container consisting of two container parts (12, 14) which are connected to one another in an opening region. Each container part (12, 14) has a single connection frame (26, 28) which includes the connection opening. The container parts (12, 14) can be connected to one another along the facing connection frames (26, 28). At least one connection frame (26, 28) includes a support device (30, 34; 54) which extends in the connection frame (26, 28) in the vertical direction.

Abstract: The invention relates to a method and to a device for producing a boat-type body (10) of a water sport device. According to the invention, a rotating frame (12), which is pre-formed about an access opening of the boat-like body (10), is arranged on an inner side of a negative mould. The outer shape of the boat-type body (10) is predetermined, essentially, by the innerside of the negative mould. The boat-like body (10) is produced in the inner side of the mould by means of a thermoplastic shaping method. During the shaping process, at least one part of the surface of the rotating frame (12) is in contact with the boat-like body (10) which is formed by the thermoplastic shaping method. The invention also relates to a water sport device.

Abstract: The invention relates to an arrangement for receiving a mould comprising at least two die platens (14, 16) arranged on a base frame (12), at least one of said die platens (14, 16) being displaceably arranged on the base frame (12), and the front sides (15, 17) of the die platens (14, 16) essentially facing each other. At least one locking element (38 to 44) is displaceably arranged by means of a locking mechanism in such a way that it can be displaced from an inserted position, wherein the locking element (38 to 44) does not protrude from the surface of the front side (15, 17) of the first die platen (14, 16), at least into a second withdrawn position, in which the locking element (38 to 44) protrudes into a receiving opening (54 to 60) provided in the front side (15, 17) of the opposite die platen (38 to 44).

Abstract: The invention relates to a device for transporting and/or storing an especially liquid medium, which comprises a relatively thin-walled plastic inner container (1) that receives the medium and an outer container (4) that encloses the inner container like a trough. At the top, said inner container (1) is provided with a filling opening that is configured as a threaded tube (2), and at the bottom, if required, with a drain opening (3). The outer container (4) consists of a pallet-type support (5) that supports the inner container (1) on its underside and a jacket (6) that adjoins the support (5). The inner container (1) is secured in the outer container (4) by means of a cover plate (8) fastened on the outer container (4).

Abstract: A large-volume container for holding liquid media is composed of two shell-like end parts each having a ring-shaped flat contact surface, and at least one sleeve-like middle part composed of two ring segments and provided with two ring-shaped flat contact surfaces and an opening for filling and emptying. The two end parts as well as the ring segments of the middle part are manufactured by blow molding with an inner layer and an outer layer, are provided with external stiffening ribs formed as chambers, and are connected in the areas of their contact surfaces by an inner and outer weld. The two end parts as well as the ring segments have in the areas of their contact surfaces a circumferential chamber, wherein the contact surfaces have at their circumferential boundary edges backwardly extending inclinations for forming welding grooves between the end parts and/or the ring segments.

Abstract: The invention relates to a device for storing liquids comprised of a plastic container, which is produced by a blowing process, which has a single layer or multilayer wall, and which is provided with at least one filling and emptying opening. The aim of the invention is, on the one hand, to economically manufacture a device of the aforementioned type by using inexpensive forming tools and, on the other hand, to be able to transport the device from the production site to the storing site also without incurring large expenditures. To this end, the container (1) is formed from at least two separately manufactured and largely identical container parts (2, 3), each of which comprising an approximately rectangular cross section with an underside (4) and a upper side (5) and having a height that is considerably greater than the largest cross section measure.

Abstract: The invention relates to a method for producing a large-volume cup-shaped or tub-shaped container made of a synthetic thermoplastic material, whereby a compact plastic, flexible hose-type preform (6) is extruded to obtain a given length and the container (1) is subsequently shaped. In order to carry out said operations with the aid of extremely simple extrusion devices and moulds, thc extruded preform (6) is expanded to a given size and a core (2) is moved upwards into the expanded preform (6). The lower, open end of the expanded preform (6) is then clamped against the core (2) to provide a seal and the preform is shaped by air in order to form a container.

Abstract: This invention concerns a drum-like container made of a discontinuously extruded hose-like perform of thermoplastic in a blow molding process. The drum-like container has a wall consisting of an inner layer, an outer layer, and at least one intermediate layer. To make it possible to monitor the fill level of the fill material, the wall has a visual indicator strip of translucent plastic running in the axial direction.

Abstract: A device for protecting a large-volume container for liquid, slow-flowing, powdered, or granular materials during storage and transport, has a pallet support body to support the container from underneath and a jacket body, which is connected to the pallet support body and which surrounds the sides of the container. The support body and the jacket body are made as an integral unit consisting of a three-layer plastic wall. The three-layer plastic wall has a compact outer layer, a compact inner layer, and a foamed intermediate layer. The device is produced by extruding a predetermined length of a tubular preform with a three-layer wall of plastic into an opened mold. Several vertical, rod-shaped spreading elements are positioned inside the tubular preform. The tubular preform is expanded by moving the spreading elements in a radially outward direction relative to the tubular preform by a predetermined outward movement.
