Description

The utility model relates to rigid packaging intended for packing, storing and transporting industrial bulk and / or resin-like products with variable viscosity (for example, construction bitumen, bitumen mastics, etc.), when transporting goods along land or waterways.

A medium-tonnage container of the "Clovertainer" type is known from the prior art, intended for storage and transportation of petroleum products having a softening temperature of at least 35 ° C: petroleum bitumen, tar, petroleum mastics. The container consists of a square pallet and a lid equipped with a filler opening, connected by vertical posts made in the form of longitudinally oriented panels. Between the pallet, the lid and the uprights, there is a shell made by winding a flexible material with an inner surface covered with an adhesive material. Each of the four sides of the shell is made concave and is held in a concave state by a vertical stand corresponding to each of the four sides (see RF patent No. 96848, IPC B65D 88/12 (2006.01), 2010).

The disadvantages of the known utility model are the large number of elements made of heterogeneous materials required to ensure the rigidity and tightness of the structure. As a result of exposure to high temperature stresses, arising, for example, when packing a bitumen product heated to a temperature required for industrial filling, equal to 160-200 ° C, moisture boils out from the inner layers of the container elements, leading to drying out and their deformation. As a result, the tightness of the joint of the joints of the wood pallet and the cover made of sheet plywood with a winding shell made of glued cardboard can be broken.

A collapsible transport container is also known from the prior art, comprising a lid provided with a filler opening. The container has a frame of four parts connected along the vertical edges with the possibility of folding into a flat structure. The frame is equipped with a bottom consisting of two elements that can be folded into a flat structure. On the inner side of the frame, a bag-insert with a siliconized inner layer is fixed with the ability to unfold along the inner volume of the frame (RF patent for utility model No. 146276, IPC B65D 5/00 (2006.01), publ. 10.10.2014).

The disadvantage of the utility model is the inconvenient and laborious process of fixing the liner-bag to the inner surfaces of the frame walls, as well as the need to observe the proportionality of the size of the liner-bag and the frame in order to avoid the formation of folds or tension of the liner-bag material when straightening in the inner volume of the frame. The use of metal staples as fastening of the liner-bag can lead to tears of the paper material and complete tearing of the liner from the walls of the frame at the time of loading the product.

Known transport container containing a shell formed from a circular fabric material, which extends between the lower part and the upper part in such a way that the volume of the container is formed for receiving granular, liquid, viscous or semi-liquid substances, in particular bitumen. Four stabilizing elements are provided, which run along the shell from the region of the lower part to the region of the upper part, the ends of which, at least in the region of the lower part, are connected by means of a fastening structure. The stabilizing elements are made in the form of pipes, which are located on the outer surface of the shell. The fastening structure contains a plurality of tensile and compression-resistant metal profile frames or elongated spacers, in particular flat iron rods, which are flush at their ends and form preferably a substantially square support surface (see RF patent No. 2720650, IPC B65D 88 / 16 (2006.01), 2020).

The disadvantage of this solution is the high metal consumption due to the implementation of the frame made of metal. In addition, the implementation of the inner shell of fabric material does not ensure the reliability of storage of bituminous materials.

Known folding container, consisting of a reservoir, consisting of a soft material and a rigid frame containing at least one upper frame, and a rack with a size substantially equal to the height of the reservoir. Each post is nested in the upper frame body and connected to the outer wall of said reservoir (see patent FR 2158093, IPC B65D 19/00; B65D 25/00, 1973).

The disadvantage of this solution is that the tank is made of linen material, which does not allow it to be used for transporting bitumen. In addition, the disadvantage is the high metal consumption, since the frame is made of metal pipes.

The closest solution is a transport container for bulk bitumen containing rectangular containers inserted into each other. The outer container is made in the form of a container containing a quadrangular base with a cargo platform equipped with protrusions for positioning the inner container, and a power contour fence fixed on the base (RF patent for utility model No. 192940, IPC B65B 63/08 (2006.01), 2019) ... This decision was made for a prototype.

The disadvantages of the known utility model are the need to ensure high precision in the manufacture of parts of the plug-in container made of thin sheet steel at all stages of the production cycle, in order to ensure the reliability and tightness of the finished product for packaging liquid bitumen and / or other liquids. In addition, upon completion of the operations of aligning the container parts with each other, as well as welding or folding works with the formation of hermetically sealed connecting seams, it is necessary to carry out a long-term hydraulic or thorough electromagnetic control of these joints for permeability (violation of the continuity of the welded seam), in order to detect and correct defects. which significantly increases the technological chain of production, as a result of which the increase in the volume of production of products is limited.

The technical problem solved by the present utility model is weight reduction while maintaining the strength and reliability of the container and simplifying its assembly.

Also, the utility model solves the problem of reducing the complexity of carrying out operations for the assembly of containers.

The technical problem posed is solved due to the fact that in a known transport container for bulk bitumen containing containers inserted into each other, the outer container is made in the form of a container containing a base with a loading platform and a power contour fence fixed on the base, in accordance with the utility model, the inner plug-in container is made in the form of a sealed multilayer heat-resistant shell made of a polymer composition.

The sealed multilayer heat-resistant shell of the plug-in container consists of three layers, interconnected by a thermoplastic adhesive layer.

The sealed multilayer heat-resistant shell of the plug-in container has outer layers with increased anti-adhesive properties.

The sealed multilayer heat-resistant shell of the plug-in container contains an inner reinforcing layer.

The sealed multilayer heat-resistant shell of the insert container contains an outer layer with barrier properties for ultraviolet radiation and water vapor and / or oxygen permeability.

The insert container is made with a lid with a receiving opening.

The plug-in container is made with a lid equipped with a filler sleeve.

The power contour fence of the outer container contains side and end walls made of moisture-resistant plates of sheet fiber and / or wood-laminated material.

The upper supporting edges of the side and end walls of the power contour fence of the container are fixed with a cover plate made of moisture-resistant sheet wood fiber material with mirror-applied protrusions.

The technical result from the use of all the essential features of the utility model is to reduce the tare weight while maintaining high consumer qualities. The developed container has increased hermetic properties to ensure the packaging of hot bitumen by the method of open vertical filling with an industrial heating temperature of up to 200 ° C, and also provides multi-tiered storage and transportation of products by land transport, as well as shipping by sea, taking into account the conditions of inertia forces acting on the cargo, arising when the vessel is on the rough sea surface.

The implementation of the internal plug-in container in the form of a sealed multilayer heat-resistant shell made of a polymer composition can significantly reduce the weight of the container while maintaining high consumer qualities.

In addition, the use of sheets of fibreboard material as a material for the side and end walls of the body made it possible to ensure the optimal and maximum permitted loading of the cargo compartment of the vehicle when delivering container elements to the warehouse terminals of consumers, which makes it possible to reduce the operational time of filling the warehouse with new packaging, as well as failures. in the continuous supply of collected containers to the place of filling, while the filling of warehouses for storing finished products increased by at least 126%.

The shipping container for bulk bitumen contains containers inserted into each other, outer 1 and inner 2 (see Fig. 1). The outer container 1 is made in the form of a container containing a base 3 with a loading platform and a power contour fence 4 fixed on the base 3. The inner plug-in container 2 is made in the form of a sealed multilayer heat-resistant shell made of a polymer composition.

The assembled outer container 1, made in the form of a container, can be closed by a fixing cover plate 5 with positioning locks and covered with horizontal and vertical strips of stripping tape.

The base 3 of the outer container 1 shown in FIG. 2 (a, b), has a polygonal lattice shape, predominantly rectangular, and includes a rigid frame consisting of longitudinal 6 strips located with a gap on the outer 7 and inner 8 transverse supports, interconnected by the outer 9 and inner 10 longitudinal runners. The specified parts of the base 3 are made from blanks of wood material and are fastened together in a generally known way, for example, by a nail or hardware connection. Along the perimeter of the upper surface of the longitudinal strips 6, there are spaced platforms 11 having a trapezoidal shape, made of wood-laminated material, along the longest of which a metal strip 12 of an L-shaped cross-sectional profile is fixed, designed to connect the base 3 and the side and end walls of the outer container to each other. containers 1. The fixing of the distance platforms 11 with the base 3 is also carried out by a well-known method of fastening, for example, using a nail or hardware connection.

To ensure a flat and continuous (without gaps) surface of the cargo platform of the base 3, a floor pad 13 is used, made of paper or wood-fiber board material, which in turn also increases the consumer properties of the container and reduces the risk of product damage.

It is also possible to make the base 3 of a standard configuration from wood blanks in the form of a pallet corresponding to international standards, and the connection with the side and end walls of the container of the outer container 1 can be provided by a known fastening method (for example, a tongue-to-plate locking system made of sheet steel, string tie systems, etc.).

The outer container container 1 shown in FIG. 1 contains at least two opposite side 14 and end 15 walls. The walls 14, 15 can be made of several plates (see Fig. 3), predominantly rectangular, of sheet fiber and / or wood-laminated material, connected by a flat metal bus 16 by a generally known method (for example, indentation, etc.) ... The slabs from which the walls 14, 15 are assembled are pretreated along the length b to form panels with a cross-sectional profile of length l (see Fig. 4). Pre-processing of the edges is necessary to ensure a tight abutment of the side 14 and end 15 walls to each other when they are connected. Side 14 and end 15 walls can be connected to each other (see Fig. 5) using a collapsible - locking 17 (for example, a piano hinge with a removable axis or a "tongue - plate" locking system made of thin sheet steel) or non-separable - hinged 18 connections (for example, a flexible metal patch strip). The fixing elements are fixed on the outer sides of the walls by a generally known fastening method.

The inner plug-in container 2 is made in the form of a sealed multilayer heat-resistant shell made of a polymer composition, which allows industrial packaging of bitumen products with an initial heating temperature of up to 200 ° C. The sealed multilayer heat-resistant shell of the insert container 2 can consist of three layers, outer 19, 20 and inner reinforced 21, bonded to each other by a thermoplastic adhesive layer 22 (as shown in Fig. 6). The interaction of the layers of a sealed multilayer shell gives the shell especially strong properties of resistance to mechanical tension of the film material, which occurs at the time of filling the insert container 2 with hot liquid (bitumen). However, the number of layers can be increased to reasonable limits to improve the reliability of the shell, or reduced to two layers.

The outer layers 19, 20 of the sealed multilayer heat-resistant shell of the insert container 1 have increased anti-adhesive properties.

One of the outer layers, 19 or 20, of the sealed multilayer heat-resistant shell of the insert container 2 has barrier properties for ultraviolet radiation and permeability of water vapor and / or oxygen.

The inner insert container 2 shown in FIG. 7-10, made in the form of a sealed multilayer heat-resistant shell, is made of flat blanks and contains a bottom 23 and vertical sides 24. The inner insert container 2 can be made closed (see Fig. 8-10), and contain a lid 25 with a receiving opening 26, designed to reduce the risk of splashing liquid products after the moment of unloading the installations for pouring hot bitumen and moving the loaded container to the warehouse with specialized equipment on the road surface having irregularities. In addition, if it is possible to store packaged products, in the absence of outbuildings and covered storage areas, the internal insert container 2 can be made with a filler sleeve 27, which, after packaging, is pulled together with a packing tape, thereby protecting the product from atmospheric precipitation. and other foreign inclusions. The connection of all parts of the inner plug-in container 2 is carried out due to the contact plastic diffusion of two homogeneous surfaces of layers 19 and / or 20, which also include adhesive components activated by high temperatures during continuous constant heating under pressure and / or pulsed heating of the free edges of the blanks and / or using ultrasonic equipment, to form a strong sealed welded joint.

Power contour fence 4 of the container of the outer container 1 can be equipped with a fixing cover plate 5 (see Fig. 1), which is a flat platform (see Fig. 11, 12) of rectangular shape, made of wood fiber and / or wood-laminated material. The cover plate 5 consists of a flat blank 28 with a cutout 29, to which, on the longest side, the blanks of plates 30 of a predominantly rectangular shape made of wood-fiber and / or wood-laminated material adjoin. These blanks of plates 28, 30 are connected to each other by a flat metal bus 31, fixed by a generally known method (for example, indentation, hardware, etc.). The positioning and fixing of the cover plate 5 on the upper supporting edges of the side 14 and end 15 walls of the power contour fence 4 of the container is provided by the sides 32, hinged by means of flexible plate connectors 33 to the plates 30. The inner surfaces of the sides 30 after bending (folding) the plate connectors 33 are adjacent to the outer surfaces of the side 14 and end 15 walls. The positioning of the cover plate 5 is also ensured by the presence of rectangular projections 34 fixed to the plate 30 by a generally known fastening method. The protrusions 34, when installing the cover plate 5, engage with the inner surfaces of the upper edges of the side 14 and end 15 walls of the power contour fence 4 of the container and are intended for clear positioning of the cover plate 5 relative to the container. In addition, in order to carry out multi-tiered land and / or sea transportation of loaded containers in the compartments of the vehicle, the fixing cover plate 5 is also provided with external rectangular projections 35, the thickness of which is at least equal to the thickness of the plates 28 and 30, fixed by a generally known fastening method.

It is also possible to use a standard cover and / or lattice frames made in the form of a tray with limiters against displacement of the upper tiers, made of standardized materials produced by the serial industry.

The assembly of the shipping container shown in FIG. 1 is carried out as follows.

On the remote platform 11 of the base 3, the power contour fence 4 of the container is installed and fixed from displacement, ensuring the unity of the structure due to the collapsible - lock connection 17. Then, the internal plug-in container 2 is installed inside the power contour fence 4 of the container, having previously straightened the bottom 23 and the vertical sides 24. The inner plug-in container 2 is fixed to the upper edges of the side 14 and end 15 walls of the power contour fence 4 of the container of the outer container 1 by a hardware fastening method. The collected container is covered with plate 5 and covered with vertical and horizontal belts of stripping tape, after which it is sent to the place where hot bitumen is filled.

The proposed utility model, due to simple design solutions, provides a simple and easy process for assembling containers, has the necessary rigidity, providing multi-tiered transportation and storage of liquid bitumen with a volume of 1 to 2 cubic meters with an industrial heating temperature for filling into containers up to 200 ° C at storage (laboratory destructive static force up to 22 633 kgf) and transportation by sea, taking into account the conditions of inertia that arise when the vessel is on the rough sea surface.

The possibility of implementing the inventive transport container with a plug-in shell for bulk bitumen is not in doubt and is confirmed by the currently developed technological maps and is easily implemented using standard equipment.
