Freight container

Abstract

The present invention is directed to a freight container comprising a floor, a roof (D), and a plurality of walls comprising at least a front end wall and side walls (A). These walls (A) and roof (D) each comprise at least one panel having two surface dimensions in relation to the container. The panels comprise a fibre-reinforced wall material, comprising a first and a second outer fibre layer (1, 6, 7,12), and at least a first and a second intermediate fibre layer (2, 3, 4, 5, 8, 9, 10, 11) arranged in between the first and second outer fibre layers. The fibres of the outer fibre layers are aligned along an outer fibre direction and the fibres of the intermediate fibre layers are aligned respectively along a first and second intermediate fibre direction which are mutually transverse and inclined with respect to the outer fibre direction. The outer fibre direction is aligned with a shortest of said surface dimensions of said panels.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to a freight container comprising a floor, a roof and a plurality of walls that form, in use, a door wall, a front end wall and a plurality of side walls and optionally side end walls that extend in between the roof and the floor of the container, said container defining a length direction of the container extending parallel with the floor and the side walls, said container defining a height direction of the container extending parallel with the corner posts.BACKGROUND[0002]To enable efficient supply chain systems to be implemented, freight containers are preferably of a standard size, such as freight containers conforming to the ISO standards for containers. An ISO (International Standards Organization) container is a freight or shipping container that complies with one or more relevant ISO container standards, such as the ISO 1496 series.[0003]Types of freight containers may vary according to their application, but incl...

Benefits of technology

[0017]By realising that it is only the front end walls, and where applicable the side end walls or roof end parts, that require these strict requirements with respect to forces such as shear stress (side end walls roof end parts) and multidirectional stress (front end wall), the weight of the container as a whole can be reduced considerably. This is an important improvement in the field of composite containers, as it will be appreciated by the skilled person that the total weight of a freight container is a main cost driver in the transportation industry. Moreover, the more weight reduction, the least energy there is required for handling, lifting or moving the container from A to B. Therefore, the light weight container of the invention also provides environmental advantages.

[0018]Preferably, at least part of the roof and/or the side walls of the container comprises the fibre-reinforced wall material, wherein, in the roof and the side walls, the outer fibre direction is directed transv
