A container (1), especially a fluidized container, including a housing upper part (2) and a housing lower part ( 3) is provided. The housing parts are detachably interlinked in an annular separation zone which is provided with a sealing element. The container in accordance with the invention provides that (i) the two housing parts are interlinked by coupling elements (8, 9) that engage with one another in a positive manner and that allow a limited movement in the direction of separation; (ii) the container parts are retained in a sealing position with a predetermined separation point ( 7) by means of a retainer (5), in which position an elastic sealing element (10) sealingly rests against the two coupling elements; and (iii) the coupling elements acts as a limiting stop when a maximum container pressure is exceeded, the predetermined separation point is activated and the housing parts are displaced towards the direction of separation.

The invention claimed is: 1. An, explosion-proof fluidized-bed container (1), comprising an upper housing section (2) and a lower housing section (3), said housing sections being connected together in a detachable ring-shaped zone of separation, and a seal is located in the zone of separation, wherein: (i) the upper and lower housing sections are connected via coupling parts (8), (9) that engage one another in a form locking manner in the zone of separation, said coupling parts permitting limited motion in a direction of separation; (ii) the container sections are held in a sealed position by a support (5) having at least one designed break point (7) including at least one shear element (6) which connects the support (5) to one of the housing sections (2), (3), the seal comprising an elastic sealing element (10) laying against the two coupling parts; and (iii) the coupling parts form a limit stop when a maximum container inner pressure is exceeded, the at least one designed break point is activated and the housing sections are shifted in the direction of separation. 2. The fluidized-bed container according to claim 1, wherein the coupling parts (8), (9) comprise a retaining rim on one of the container sections having a U-shaped cross section with an open side thereof facing inward, and on the other of the container sections, an annular flange facing outward that extends into the retaining rim; the annular flange is located between the sealing element (10) that is positioned in the retaining rim and a free side-flange of the retaining rim; and an inner side of the free side-flange of the retaining rim and a side of the annular flange facing it form stopping surfaces that are spaced apart from one another in normal operation. 3. The fluidized-bed container according to claim 1, wherein the upper housing section (2) is connected rigidly to the support (5) and the lower housing section (3) is connected to the support (5) through the at least one shearing element (6) included with the designed break point (7). 4. The fluidized-bed container according to claim 3, wherein the shearing elements are shear pins. 5. The fluidized-bed container according to claim 1, wherein the sealing element (10) comprises an expandable, inflatable hollow seal. 6. The fluidized-bed container according to claim 1, wherein at least the lower housing section (3) is made of duplex steel. 7. The fluidized-bed container according to claim 6, wherein at least the upper housing section (2) and the lower housing section (3) and optionally, shear elements (6) that comprise the designed break point and/or the support (4), (5 ) are made of duplex steel. 8. The fluidized-bed container according to claim 6, wherein the duplex steel contains, by weight fraction, 4.5 to 6.5% Nickel, 21 to 25% Chromium, 0.3 to 3.5% Molybdenum, no more than 0.03% Carbon, 0.08 to 0.20% Nitrogen and, in addition to possible traces of common impurities, Iron in the amount of the difference from 100%. 9. The fluidized-bed container according to claim 6, wherein the duplex steel contains, by weight fraction, 4.5 to 6.5% Nickel, 21 to 23% Chromium, 2.5 to 3.5% Molybdenum, no more than 0.03% Carbon, 0.08 to 0.20% Nitrogen and, in addition to possible traces of common impurities, Iron in the amount of the difference from 100%. 10. An explosion-proof fluidized-bed container (1) comprising an upper housing section (2) and a lower housing section (3), said housing sections being connected together in a detachable ring-shaped zone of separation, and a seal is located in the zone of separation, wherein: (i) the upper and lower housing sections are connected via coupling parts (8), (9) that engage one another in a form locking manner in the zone of separation, said coupling parts permitting limited motion in a direction of separation; (ii) the container sections are held in a sealed position by a support (5) having at least one designed break point (7) which connects the support (5) to one of the housing sections (2), (3), the seal comprising an elastic sealing element (10) laying against the two coupling parts; and (iii) the coupling parts form a limit stop when a maximum container inner pressure is exceeded, the at least one designed break point is activated and the housing sections are shifted in the direction of separation, wherein the sealing element (10) maintains a seal between the coupling parts (8), (9) throughout a range of travel defined by the limit stop, whereby the container remains sealed when the maximum container inner pressure is exceeded and the designed break point is activated.
