Embodiment Construction

[0042] figure 1 A container 1 according to the invention is shown, which is designed, for example, as a fuel container for a motor vehicle. The container 1 is produced from a thermoplastic material by extrusion blow molding of a preferably multilayer extrudate based on polyethylene. In principle, the invention is understood to be such that the container 1 can also be produced as a so-called single-layer container based on a single-layer extrudate made of thermoplastic plastic. The container 1 has a container wall 2 which encloses a filling volume. exist figure 1 In the embodiment shown in , the container 1 is constituted as a so-called saddle box comprising two interconnected chambers, the present invention should of course be understood in such a way that the container 1 may have any configuration. The container 1 can, for example, be shaped as a simple cuboidal or cuboidal structure.

[0043] The container wall 2 of the container 1 can have a relatively large-area wall r...

Abstract

The invention relates to a container (1) made from thermoplastic polymer having at least one interior reinforcement rib (3) in a container wall, wherein the reinforcement rib (3) is formed by at least one linear groove track (4) in a container outer wall (2a), the groove track (4) extends over a length on the container outer wall (2a), the groove track (4) is formed by a plurality of recesses (5) in the container outer wall (2a) which are arranged at a distance to each other and wherein there are material bridges (6) between each of the recesses (5), each of which material bridge has a smaller depth than the recesses (5). The invention further relates to a method for producing such a container (1) by extrusion blow molding or deep drawing.

Description

technical field [0001] The invention relates to a container made of thermoplastic plastic, which container comprises at least one internal reinforcing rib in the container wall. [0002] The invention also relates to a method for producing such a container. Background technique [0003] It is known in principle to provide containers made of thermoplastic plastic with reinforcing ribs which increase the bending stiffness and compressive strength of the container wall. In the case of bottles, for example, it is known to provide the bottles with a surrounding rib. In injection molded containers it is known to form reinforcing ribs onto the container wall. Such a rib can be designed in such a way that it protrudes into the container volume and thus also at the expense of the container volume. Alternatively, reinforcing ribs can be arranged on the outside on the container wall, which could be inconvenient depending on the intended use of the container. In injection molded pla...
