TECHNICAL FIELD
[0001] The invention relates to a blast-resistant container for transporting and storing products containing an explosive material.
BACKGROUND
[0002] Typical blast-resistant containers have a housing with a lid and legs. Inside the container there is a recess for products containing explosives, which is surrounded by a layer for damping explosion energy. The layer for damping explosion energy may comprise sand, sawdust or plastic bottles filled with water.
SUMMARY
[0003] In the blast-resistant container according to the invention, clamping rings are mounted on the periphery of the housing. The clamping rings comprise eye bolts with nuts. On the periphery of the housing there are further mounted transport couplings and a lower housing of the axle. Under the lower housing of the axle there is mounted a retaining support and fasteners for protective cover cord. The housing is closed with a container lid, which has an upper ring and a lower ring with rods passing through the ribs, the rods being mounted to the upper and lower rings, wherein the rods of the upper ring are mounted at the height of gaps between the rods of the lower ring. The upper housing of the axle, brackets of eye bolts and the handle are attached to the container lid. The container lid is coupled with the housing by means of the axle ended with the back nut on one side and securing nut on the other side. Plastic containers with water (non-flammable liquid) are placed inside the housing, on the floor mounted to the bottom supports, between thick, second boards and stops. The recess with the cover is placed in middle part of the inside of the housing and a shelf is placed inside the recess.
[0004] There is disclosed a blast-resistant container comprising a housing with a lid. The housing has a recess defined by first boards, a floor and a cover. The recess is surrounded by stops, plastic containers with non-flammable liquid and second boards. The stops and the second boards are arranged to define a space in which plastic containers with non-flammable liquid are placed. The second boards are positioned adjacent to the side walls of the housing.
[0005] Preferably, the lid is rotatably attached to the housing via an axle so that the plane of rotation of the lid with respect to the housing is parallel to the floor.
[0006] Preferably, the housing comprises a tubular side wall, which comprises a clamping ring, to which eye bolts are pivotally attached substantially evenly along the circumference of the housing's side wall; and the lid is round and comprises brackets for eye bolts so that the eye bolts can be releasably secured in these brackets using nuts, thereby allowing to lock the housing with the lid.
[0007] Preferably, the lid comprises an upper ring, a lower ring and wherein the upper ring and the lower ring comprise rods arranged so that the rods of the upper ring are aligned above the empty spaces created between the rods of the lower ring.
[0008] Preferably, the lid comprises ribs secured in the upper ring and the lower ring, so that the rods of the upper ring and the lower ring traverse through the ribs.

DETAILED DESCRIPTION
[0012] The blast-resistance container comprises a housing 1 in form of a tube ended with a bottom 2, to which assembly legs 3 are attached. Clamping rings 4 are mounted in an upper part of the housing 1, on its periphery, in which eye bolts 5 with nuts 6, a lower housing 7 of the axle, transport couplings 8 and a retaining support 9 are mounted. Fasteners for a protective cover cord are attached in a middle part. The housing 1 is closed from the top with a container lid 11 which comprises an upper ring 12, a lower ring 13 and ribs 14. Both the upper ring 12 and the lower ring 13 comprise rods 15 passing through ribs 14. The rods 15 of the upper ring 12 are mounted between the rods 15 of the lower ring 13 at the level of gaps between the rods 15 of the lower ring. In other words, the rods 15 of the upper ring 12 are aligned above the empty spaces created between the rods 15 of the lower ring 13, as seen in Fig. 4. The upper housing 16 of the axle, brackets for eye bolts 17 and the handle 18 are mounted to the container lid 11. The container lid 11 is connected rotationally with the housing 1 by means of the axle 19, which is placed in the lower housing 7 of the axle and the upper housing 16 of the axle. The axle 19 has threaded ends onto which the back nut 20 and the securing nut 21 are screwed. The (thick) second boards 22 are placed in the housing 1 and are rested against a floor 23. The floor 23 is mounted to the bottom supports 24. On the floor 23, between the second boards 22 and the stops 25, there are placed plastic bottles with water 26 (or other non-flammable liquid). A recess 27, made of first boards 28 and comprising a cover 29 and a shelf 30, is placed inside the housing 1 in its middle part. The second boards 22 may be thicker than first boards 28.
[0013] The container can be prepared for operation as follows. First, the nuts 6 of eye bolts 5 are partially unscrewed and the eye bolts 5 are tilted back. Then, the nut back 20 is unscrewed and the container lid 11 is raised. The raised container lid 11 should be manually rotated about the axis 19 by means of the handle 18 for the container to be opened. Next, the lid 29 is removed from the recess 27 and products containing explosives can be placed on the shelf 30. When the products are placed on the shelf, the recess 27 is closed with the lid 29. After this, the container lid 11 should be turned to the original position and pressed to the housing 1 by means of the nuts 6 of eye bolts 5. The container prepared in such a manner is ready for use.
[0014] The advantage of the container according to the invention is a simple and cheap construction of the container interior, which is made of easily obtainable wooden materials. Another advantage is that, after the detonation of the explosive contained in products stored in the container, the container internal parts can be easily and quickly replaced without using any special tools.
