Embodiment Construction

[0025] figure 1 The open container housings 10 , 12 produced in a blow molding machine are shown in section, each having a circumferential flange 14 , 16 . Through holes 18 are formed in the flanges 14 , 16 , respectively, and a circumferential groove 24 is formed in the flange 16 . The container housings 10 , 12 are transported in the open state from the place of production to the point of destination, where they are connected to each other along flanges 14 , 16 in a liquid-tight manner by screw connections. The large-volume closed containers formed in this way are used at the destination as potable water tanks, waste water tanks, waste containers, rainwater receiving tanks, fire-fighting water tanks and the like. In the upper container case 10, an inlet 20 is formed.

[0026] figure 2 A perspective view of the container shells 10 , 12 is shown, each having a reinforcement 22 . The flange 16 comprises a circumferential groove 24 into which a seal 26 for the liquid-tight ...

Abstract

The invention relates to a method and a device for producing large-volume container trays (10, 12) of plastic. A tubular preform (36) is guided over a mold frame (32) which is facing two blow molds (26, 28). During the closure of the blow molds (26, 28), an encircling flange (14, 16) is formed on the outer edge of the container trays (10, 12). After blow molding, the container trays (10, 12) are cut free from the mold frame (32) along said mold frame.

Description

technical field [0001] The invention relates to a method for producing large-volume container casings from plastic material, wherein a tubular preform or parison of plastic material in a thermoplastic state is fed to at least one blow mold in an open state. Further, the invention relates to a device for producing such bulky container casings from plastic material. Background technique [0002] Large-volume containers in closed form up to 10,000 liter capacity are used as waste water tanks for potable water tanks, faecal matter containers, rainwater receiving tanks, fire-fighting water storage, etc. Such closed containers are generally produced by blow moulding. Especially in the case of large-volume containers, high transport and handling costs arise. [0003] A device and a method for producing large-volume hollow bodies from plastic materials are known from DE 10 2010 004 586 A1 by the same applicant. The vacuum cavity that completely surrounds the blow mold and preform...
