In FIG. 8 shows a photograph of containers stored across each other with open lids and with lodgements on the inner shell that fix the load - fiberglass rods, for example.

The container for storage and transportation of goods includes a body 1 (Fig. 1 and 2) and a cover 2, forming the outer shell and having on the outer surface of the ribs 3 (Fig. 1 and 7) and grooves 4 (Fig. 2), shaped flanging 5 (Fig. 6) and 6 at the ends 7 and 8, a seal 9 along the perimeter in the groove 10 along the end 7 or 8 of the body 1 or cover 2, which provides sealing when they are connected, locking elements 11 (Fig. 1), an inner shell consisting from the body 12 (Fig. 7 and 8) and cover 13 and located on the respective inner surfaces of the body 1 and cover 2 (Fig. 8). The width H (Figs. 1 and 3) of the body 1 and cover 2 are made in multiples of their length L (Figs. 1 and 2), i.e.:

where L is the length of body 1 or cover 2, m;

H is the width of the body 1 or cover 2, m;

k is a prime natural number, most often equal to 2 or 3.

With k=2, two containers can be installed perpendicular to one, and with k=2 - three, etc.

Lid 2 (Fig. 3) is additionally equipped with bypass valve 14, equalizing the pressure outside and inside the closed container. Outside, evenly around the perimeter of the side surfaces of the housing 1, handles 15 are installed (Fig. 2 and 3), which are placed along the axis 16 (Fig. 3) of the housing 1 and/or symmetrically (Fig. 2) relative to the corresponding axis 17. The handles 15 are made rotatable relative to base 18, fixed on the body 1. On the short lower edge of the body 1 (Fig. 3) symmetrically with respect to the axis, samples 19 (Fig. 3 and 4) are made for fastening the longitudinal wheels 20, made with the possibility of interacting with the transportation surface (not shown) when lifting the other short edge of the body 1 with the separation of the bottom 21 (Fig. 3 and 5) of the body 1 from this surface. From the inside of the seal 9 (Fig.6) along the perimeter of the end 7 or 8, respectively, of the body 1 or cover 2, a closed ledge 22 is made in the form of a trapezoid in cross section, tapering from the end 7 or 8, and on the reciprocal end 8 or 9, respectively, of the cover 2 or body 1 - a closed sample 23 under this protrusion 22, providing tight interaction and sealing when they are connected. The body 12 (Fig. 7 and 8) and the cover 13 of the inner shell are made in the form of a three-dimensional lattice, made with the possibility of interacting with the corresponding external compressible protrusions 24 (Fig. 8) of at least one lodgment 25, for its installation and fixation in a selected place inside body 1 of the container together with the corresponding load 26. On top of the lid 2 (Fig. 1 and 2) of the container is stamped in the form of protrusions 27 with a square or rectangular base, located on the upper surface evenly and symmetrically, and on the bottom 21 (Fig.5) of the body 1, recesses 28 (Fig. 5) corresponding to the protrusions 27 (Fig. 1), as well as grooves 4 transverse to the long side of the bottom 21, symmetrical along the axis 17 and over its entire width, parallel grooves 4 (Fig. 2) under the loader guide "forks" (not shown). The projections 27 of the lid and the corresponding recesses 28 (FIG. 5) are made in such a way that they allow the installation of similar containers with fixation from lateral movement on top of each other, offset or perpendicular to each other (FIG. 8). The body 12 (Fig. 7 and 8) and the cover 13 of the inner shell can be made removable to remove the outer shell from the body 1 and roof 2 (Fig. 8), respectively, to replace a failed grate or to install a grate with a different pitch.

Structural elements, guides, seals and technological connections that do not affect the performance of the container are not shown in the drawings (Fig.1 - 8) or are shown conditionally.

Container for storage and transportation of goods works as follows.

Based on the analysis of the volume and dimensions of cargo 26 required for transportation (Fig. 8) and the required volume of at least one lodgement 25 sufficient to protect the type of cargo 26 (glass containers, fiberglass rods, pyrotechnics and/or the like), determine the required the minimum internal volume from which the parameters (volume and internal width and length) of the body 12 and the cover 13 of the inner shell are determined, taking into account the formula [1]. Based on the total mass of the load 26 and the used lodgements 25 with compressible protrusions 24, based on the strength characteristics of the material (for example, low-pressure polyethylene (HDPE) by injection molding - the authors do not claim the material) of the inner shell, calculate the thickness of the body 12 and cover 13 and, as a consequence, the outer parameters of the inner shell. Knowing the maximum possible mass of the body 12 and cover 13 of the inner shell with lodgements 25 and weights 26, based on the external parameters of the body 12 and cover 13 and the strength characteristics of the material (for example, from sheets of SMC prepreg, that is, in the form of sheets consisting of polyester resin, fiberglass and fillers - the authors do not claim the material), determine the internal parameters of the body 1 (Fig. 1) and cover 2, as well as the wall thickness of the outer shell. After that, by calculations and modeling, the location of the outer elements of the body 1 and the cover 2 of the container is determined: stiffening ribs 3 that increase the strength, grooves 4 (Fig. 2) symmetrical to the axis 17 for the loader forks on the bottom 21 (Fig. 5), located evenly along the perimeter of the body 1 wall thickenings for locking elements 11 (fig. 1) and bases 18 (fig. 3) of rotary handles 15, on the cover 2 there is a thickening for the bypass valve, as well as samples 19 (fig. 3 and 4) of the short lower rib of the housing 1 (fig. 3) symmetrically about the axis 16 for fastening the longitudinal wheels 20, which must be installed on the body 1 with the possibility of interacting with the transportation surface (not shown) when the other short edge of the body 1 is raised with the bottom 21 of the body 1 separated from this surface. In this case, the handles 15 (Fig. 2 and 3) must be placed along the axis 16 (Fig. 3) of the body 1 and / or symmetrically (Fig. 2) relative to the corresponding axis 17 to ensure uniform distribution of the load when carried using the handles 15. Also modeling determines the size of the punchings in the form of protrusions 27 (Fig. 1) on top of the cover 2 and the corresponding recesses 28 (Fig. 5) on the bottom 21 of the body 1, and the protrusions 27 (Fig. 1) with a square or rectangular base on top of the cover 2 and recesses 28 (Fig. 5) on the body 1 are positioned so that it is possible to install similar containers with fixation from lateral movement on top of each other, offset (like brickwork) or perpendicular to each other (Fig. 8).

After obtaining the necessary parameters of the container, molds or dies are made for the manufacture of the outer and inner shells. Moreover, the body 1 and cover 2 are made taking into account the fact that the width H (Fig. 1 and 3) of the body 1 and cover 2 must be made in multiples of their length L (Fig. 1 and 2), and at the corresponding ends 7 (Fig. 6 ) and 8, shaped flanges 5 and 6 with a groove along the perimeter for seal 9 should be located. Seal 9 (Fig. 6) can be welded into groove 10 immediately during the manufacture of body 1 or cover 2 (the authors do not pretend to do this). At the same time, from the inside of the seal 9 (Fig.6) along the perimeter of the end 7 or 8, respectively, of the body 1 or cover 2, a closed protrusion 22 is also made in the form of a trapezoid in cross section, tapering from the end 7 or 8, and on the reciprocal end 8 or 9, respectively cover 2 or body 1 - a closed selection 23 under this ledge 22.

After manufacturing the appropriate molds and/or dies, the required number of cases 1 (Fig. 1) and covers 2 of the outer shell and cases 12 (Figs. 7 and 8) and covers 13 of the inner shell are produced. On the body 1 (Fig. 1) evenly along the perimeter in places of technological thickenings (shown conventionally in Figs. 4 and 6) with the help of bolts, rivets, glue or the like. install bases 18 (Fig. 3) with rotary handles 15, one part of the locking element 11 (Fig. 1) and in the corresponding selections 19 (Fig. 3) - wheels 20. On the cover 2 (Fig. 1) install the second part of the locking element 11 (Fig. 1), and after drilling a hole (not shown), bypass valve 14 (Fig. 3) for use without destructive pressure drops inside and outside the container, for example, when flying in an airplane at high altitudes. The authors do not claim the design of the bypass valve 14, since they are known in large numbers from open sources. As a bypass valve 14, it is possible to use a membrane that collapses at a certain pressure drop inside and outside the container, a spring valve that opens at a certain pressure drop, or the like. When transporting optical instruments, valve 14 is additionally equipped against dust with a filter (not shown), chemically aggressive substances with a membrane (not shown), which cuts off the chemical components of the air that can cause a chemical reaction, etc. If it is possible to get into the water (for example, during river or sea transportation), it is recommended to use a gas valve as a bypass valve 14, which closes hermetically when water enters it, excluding the cargo 26 from getting wet (Fig. 8).

After assembling the elements of the container inside the body 1 and the cover 2, the body 12 and the cover 13 of the inner shell are inserted, respectively, which, if necessary, are fixed inside the outer shell with a sealant, glue, screws or the like. In the volumetric lattice inside the body 12 with the help of compressible protrusions 24, the required number and the desired shape of the lodgement 25 (polystyrene, foam rubber, molded polyurethane, etc.) are placed for its installation and fixation in a selected place inside the container body 1 together with the corresponding load 26 The compressible protrusions 24 can be made from the material of the cradle 25 itself during manufacture, glued or mechanically attached to the cradle 24, or made from any material and attached in any known way (the authors do not claim to do this). If necessary, additional lodgements 25 can be installed on top of cargo 26 in the same way. According to the result of loading bodies 1 and 12, they are together with lodgements 25 and cargo 26 (one or more distributed inside buildings 1 and 12 at a safe distance from each other in a horizontal or vertical position ) are closed with lids 2 and 13. In this case, the lid 13 securely fixes the lodgements 25 with weights inside the cases 1 and 12 from movement. end 7 or 8 of body 1 or lid 2, and ledge 22 enters closed recess 23, reliably sealing and protecting the interior of the container from external factors, as well as excluding longitudinal movements of lid 2 relative to body 1.

The container with cargo 26 (Fig. 8), depending on the volume and weight, can be moved (transported) to the place of storage and transportation in several ways without the use of additional equipment:

1. carrying - manually using handles 15 (Fig. 1), the location of which evenly distributes the total mass of the container (gross) between them when carrying;

2. partial loading - due to the separation with the help of the handle(s) 15 with the crown of the side of the body 1, opposite to the location of the wheels 20 (Fig. 3 and 4), partial loading of the understood part on transport (for example, a low pickup truck) or manually transport the container to wheels 20;

3. loader - inserting the loader fork into the grooves 4 (Fig. 2) of the bottom 21 (Fig. 5) with subsequent lifting and transportation of the container.

Storage of several similar containers is possible with the help of protrusions 27 (Fig. 1 and 2) on the lid 2 and recesses 27 (Fig. 5) on the bottom 21 of the body 1 on top of each other, with longitudinal and / or transverse offset, as well as across each other (Fig. 8), greatly simplifying warehousing and making the stack more rigid. At the same time, the handles 15 and the ears 20, which are swivel relative to the base 18 (Fig. 3), do not protrude and do not interfere with the proper storage of containers.

The proposed container for the storage and transportation of goods allows you to protect against movement inside the container of the protective shell (lodgement), covering explosive or fragile goods, due to the use of an inner shell on the inner surfaces of the body and the lid in the form of a plastic lattice, to ensure the installation of the container on top of each other, overlapping along and / or across due to the shape and location of the corresponding protrusions and depressions on the lid and the container body, made with a multiple ratio of width and length, to provide additional tightness for the network of another seal between the lid and the body in the form of corresponding and interacting when connecting the protrusion and groove located along the perimeter of the connection, protect against pressure drops inside and outside the body by using a bypass valve, ensure rolling movement due to the presence of rolling mechanisms - wheels, and ensure carrying and transportation due to the presence of portable handles around the perimeter and recesses in the days under the fork of the loader.
