A transport container system includes a stackable crate having a bottom element and four side wall elements which are of a dimensionally and pressure stable structure. Each of the side wall elements has a foldable attachment element connected to it. When folded up, the attachment elements of the four side wall elements will form an attachment which will increase the volumetric capacity of the crates. The attachment elements will each bear on an upper side of the respective side wall element and be retained in the folded-up position by guides provided on the side wall elements. When folded down, the respective attachment elements can be integrated into the respective side wall element in such a manner that the attachment elements at least will not protrude substantially over the thickness of the side wall elements.

1. A transport container system for transporting bulk goods, comprising: a stackable crate having a bottom element and four side wall elements;wherein each of the four side wall elements includes an attachment element connected to the respective side wall element so as to be movable between a lowered position in the side wall element and a raised position for an increase of a volumetric capacity of the crate,wherein a sliding guide is provided allowing a translational movement of the attachment element between the lowered position and the raised position,wherein an upper side of the attachment element, both in the lowered position and in the raised position, serve as a support surface for a bottom element of a further crate placed atop the crate,wherein the attachment element has a thickness smaller than or equal to the thickness of the side wall element,wherein the sliding guide includes a sliding guide slot in the side wall element and a guide rod extending from an underside of the attachment element into the sliding guide slot, andwherein the guide rod includes locking elements which are arrestable in the sliding guide slot at various positions. 2. The transport container system of claim 1, wherein each of the side wall elements, together with the attachment element, is mounted to the bottom element so as to be folded up from a substantially horizontal position on the bottom element into an upright position at which adjacent side wall elements are interlockable. 3. The transport container system as claimed in claim 1, wherein the crate is configured such that the crate is stackable with the attachment element in the lowered position. 4. The transport container system as claimed in claim 1 wherein the crate is configured such that the crate is stackable with the attachment element in the raised position. 5. The transport container system as claimed in claim 1 wherein the attachment element is detachably mounted on side wall element. 6. The transport container system as claimed in claim 1, wherein the attachment element has a support surface which substantially corresponds in shape to a respective area of an underside of a bottom element of a further crate stacked on the crate so as to interlock with the further crate stacked thereon. 7. The transport container system as claimed in claim 1 wherein the attachment element is made from a same material as the side wall elements. 8. The transport container system as claimed in claim 1 wherein the side wall element and the attachment element are made from different materials. 9. The transport container system of claim 1, wherein the locking elements are arrestable such that in the lowered position of the attachment element, an underside of the attachment element is disposed on an upper side of the side wall element, and such that in the raised position of the attachment element, the underside of the attachment element is disposed at a distance from the upper side of the side wall portion.
