Embodiment Construction

[0041] first reference figure 1 , shows a part of the container wall 1 of the container 2 made of thermoplastic material in the region of the opening 3 of the container 2 . The opening 3 can be designed, for example, as an inspection hole which can be sealed with a cover. The opening 3 comprises a metal rim 4 designed as a flange ring or bayonet ring. The frame 4 can alternatively be designed as a sleeve for the leads. An annular edge 5 with holes is arranged on the frame 4, and a plurality of holes 6 are arranged on the circumference of the annular edge 5 for the thermoplastic material of the container wall 1 to pass through. The container wall 1 is produced, for example, from a single-layer or multi-layer extrusion based on HDPE. The frame can be made of steel or aluminum. As described below, the border is formed in the container wall 1 during the production of the container 2 and the opening 3 is cut out or machined by a circular machine after the container 2 is removed...

Abstract

The invention relates to a method for producing a container (2) from a thermoplastic, having at least one surround (4), provided in the container wall (1), for a container opening. The surround (4) comprises a structure behind which parts of the container wall (1) extend and/or which is penetrated by said parts. The method is carried out using a multi-part blow mold that has at least two mold parts, each having at least one cavity, wherein the surround is placed as an insert in the cavity (10) of the blow mold (7). The method comprises pressing the preform that has been forced into the cavity (10) into the structure of the surround (4) by means of a tool which is brought to bear on the preform (12) on the side of the preform facing away from the cavity (10).

Description

technical field [0001] The invention relates to a method for producing a container from thermoplastic material with at least one border for the opening of the container in the container wall. [0002] In particular, the invention relates to a method for producing a stationary container from thermoplastic material, for example as a fuel tank, a wiper container or an oil tank for a motor vehicle. Fuel tanks for motor vehicles and the above-mentioned auxiliary tanks are usually provided with filling or inspection openings with metal rims, for example in the form of bayonet rings or flange rings. The metal rim is shaped during production of the container such that the collar of the rim is fully embedded in the thermoplastic material of the container wall. To this end, the frame comprises a structure, for example, in the form of a perforated ring through which the thermoplastic material of the container wall passes. Background technique [0003] Plastic collars or plastic snaps...
