Abstract
Abstract In a freight container for flowable goods the necessary ducts for interconnecting various compartments of the container so as to enable the cotents of these compartments to be discharged completely, are in the form of troughs defined by structural elements of the container walls. This construction simplifies manufacture and facilitates cleaning of the container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A freight container for flowable goods with two end walls comprising beams, including at least one horizontal transverse beam, which are joined together to form a frame and curved wall elements inserted into the frame, corner fittings for lifting and stacking of the container attached to the frame and longitudinal container walls extending between the end walls and connected therewith fluid-tightly, said longitudinal walls comprising intersecting part-cylindrical wall sections curved about axes which are parallel to the longitudinal container axis, the longitudinal walls having at least one re-entrant saddle portion Which is parallel to the longitudinal container axis and directed into the interior of the container, wherein said horizontal tansverse beam of at least one end wall opens into the interior of the container and together with an end edge of the adjacent said longitudinal container wall defines a transverse inwardly open, trough, having a depth which is at least equal to the distance between said re-entrant saddle portion and an associated trough- or crown line of the container wall concerned.
Claim 2
Dependent Claim
171 words
A freight container for flowable goods with two end walls comprising beams, including at least one horizontal transverse beam, which are joined together to form a frame and curved wall elements inserted into the frame, corner fittings for lifting and stacking of the container attached to the frame and longitudinal container walls extending between the end walls and connected therewith fluid-tightly, said longitudinal walls comprising intersecting part-cylindrical wall sections curved about axes which are parallel to the longitudinal container axis, the longitudinal walls having at least one re-entrant saddle portion Which is parallel to the longitudinal container axis and directed into the interior of the container, wherein said horizontal tansverse beam of at least one end wall opens into the interior of the container and together with an end edge of the adjacent said longitudinal container wall defines a transverse inwardly open, trough, having a depth which is at least equal to the distance between said re-entrant saddle portion and an associated trough- or crown line of the container wall concerned.
Claim 3
Dependent Claim
30 words
A freight container according to claim 1, including a filling- and discharge device connected to the trough, the latter being formed by a lower transverse beam of said end wall.
Claim 4
Dependent Claim
28 words
A freight container according to claim 1, wherein the trough is formed by an upper transverse beam of an end wall provided with an inspection- or venting aperture.
Claim 5
Dependent Claim
35 words
A freight container according to claim 1, wherein the frame comprises hollow, rectangular beams, and wherein the portion of the vertical inner wall of a transverse beam which is located inside the container is omitted.
Claim 6
Dependent Claim
57 words
A freight container according to claim 1, wherein the frame comprises hollow, rectangular beams and wherein the transverse beam forming the transverse trough comprises a horizontal boundary wall and a vertical sheet metal element, which connects said boundary wall with the longitudinal wall of the container, the end wall being directly joined to the horizontal boundary wall.
Claim 7
Dependent Claim
48 words
A freight container according to claim 5, wherein the longitudinal walls of the container are part-cylindrically curved about horizontal axes, a filling- and a discharge socket being attached to the vertical sheet metal element between the curved portion of the container and a corner of the end wall.
Claim 8
Dependent Claim
34 words
A freight container according to claim 1, having an obliquely extending tie rod between the re-entrant saddle portion and an intersection line of an end wall defined by a plurality of curved wall elements.
Claim 9
Dependent Claim
26 words
A freight container according to claim 7, having an external reinforcing fillet at the intersection line between two wall elements inserted in the end wall frame.
Claim 10
Dependent Claim
18 words
A freight container according to claim 1, having a reinforcing beam mounted externally on the horizontal transverse beam.
Claim 11
Dependent Claim
22 words
A freight container according to claim 9, wherein the reinforcing beam is of closed cross-section and provided with connection for heating means.
