Description

[0001] Containers for logistics made from infusion composites.

[0002] FIELD OF APPLICATION:

[0003] 1. The aforementioned product, whose protection will be claimed in this report, was developed with the aim of addressing deficiencies, mitigating difficulties, and solving problems previously encountered by users in the sector, more specifically, the rail, road, and waterway freight transport sectors.

[0004] INTRODUCTION:

[0005] 2. This patent application for invention relates to a composite box whose function is to improve and facilitate the transport of cargo.

[0006] 3. The materials used in the construction of tanks, truck bodies, containers, passenger wagons, and various cargo vehicles vary depending on the type of cargo they are designed to transport and the necessary safety specifications.

[0007] 4. Carbon Steel: Widely used due to its durability and strength. Suitable for transporting non-corrosive liquids, such as fuels and less aggressive chemicals.

[0008] 5. Stainless Steel: Used to transport corrosive products, such as aggressive chemicals and liquid foods. Corrosion resistant and easy to clean, maintaining the purity of the contents.

[0009] 6. Aluminum: Used for tanks that require lightness and corrosion resistance. Common in the transportation of food and beverages.

[0010] 7. Fiberglass Reinforced (FRP): Used for highly corrosive chemicals. Lightweight and corrosion-resistant, but not as impact-resistant as steel.

[0011] 8. Reinforced Plastic (Composites): Used for specific containers with lower weight and load capacity. Offers corrosion resistance and design flexibility.

[0012] 9. Depending on the cargo being transported, a chemical reaction may occur, for example, the creation of acids that corrode the metal. The choice of material should always take into account the type of acid, the concentration, the temperature, and the duration of exposure to ensure the durability and safety of the equipment. It is worth noting that some pesticides used in agriculture can react with water during the washing of the compartment and create various acids that can corrode the surface. 10. This product stands out fundamentally for its practical, simple, and functional form in a logistics container, possessing unique, exclusive, and innovative functional aspects, which will be described below, making it an exclusive product on the market.

[0013] CHARACTERISTICS:

[0014] 11. The product in question, presented through this report, is composed of: the logistics boxes (1) are made 100% of composites, also called plastic steel, their shape may vary, however, the sides of the product must be inclined towards the center at the bottom, so that the load is directed to the center of the product and facilitates unloading; the product also has a solar panel (2) on top, which will generate energy to assist in the movement or maintenance of refrigerated cargo.

[0024] 21. It should be clarified that the images above illustrate the product in a demonstrative and non-restrictive manner, whose design may vary in terms of its measurements, raw materials, dimensions, etc., without logically deviating from the main scope for which protection is claimed.

[0025] FUNCTIONALITY:

[0026] 22. Initially, the aforementioned product, described in this report, will be used in the freight transport sector.

[0027] 23. Innovation lies in mixed chassis for the transport industry, combining steel and pultruded fibers. This combination provides a weight reduction of up to 60%, greater mechanical and corrosion resistance, thermal insulation, and ease of maintenance. The resulting material density (1,800 kg / m³) 3 ) is significantly lower than that of steel (7,800 kg / m 3 ), titanium (4,500 kg / m 3 ) and aluminum (2,800 kg / m 3 This allows for a considerable reduction in the mass of light, medium, and heavy vehicle chassis. This translates into lower fuel consumption and greater load capacity.

[0028] 24. Additionally, the innovation presents the development of polymer composite containers for logistics, such as boxes and bins. The use of infusion composites offers high resistance to impacts and weathering, greater durability compared to conventional steel, as well as weight reduction and increased load capacity. Together, these three proposals demonstrate the potential of innovation and the use of sustainable materials to create high value-added products with significant economic and environmental benefits.

[0029] 25. This patent presents a new design for logistics containers that are lighter because the top is made of a special material called "plastic steel." This material is made of glass fiber reinforced plastic and resins. It is created through a process that makes it similar to steel, but with several advantages.

[0030] 26. Advantages include being up to 70% lighter than common steel, recyclable, rot-proof, having low thermal conductivity, being highly resistant to chemicals, being non-porous (which facilitates cleaning and hygiene), being impermeable to dielectrics (materials that do not conduct electricity), having high mechanical strength, electrical insulation, being non-flammable, maintaining its stable shape, being compatible with organic materials, and allowing the integration of multiple functions in a single material.

[0031] 27. The main objective of the product is to ensure a significant reduction in mass for all logistics modes (rail, road and water), among several other economic and socio-environmental advantages, in addition to the protection of commodities, such as, for example, granulated sugar.

[0032] 28. Currently, these sugars adhere to the walls of the steel wagons due to the heating of the steel at high temperatures, resulting in an unloading time of approximately 6 hours and requiring manual removal with silicone mallets, which is a step backward and a waste of time.

[0033] 29. Composites are a mixture of chemical components in various natural forms, generating a component with high chemical and mechanical resistance, thermal insulation, and static electrical resistance, with low weight, resulting in multiple cost savings in its use and excellent advantages in protecting commodities without altering their natural state.

[0034] 30. Composites, with their high characteristics, can be used in various sectors of the Brazilian and international markets. They are used in logistics transport: rail freight, road passenger transport; refrigerated trucks; and water transport in containers, with the advantage of being a product with reduced mass compared to steel. Comparisons: composites with a specific weight of 1800 kg / m³. 3 steel with a specific gravity of 7,900 kg / m³ 3 Aluminum, specific gravity 2,800 kg / m³ 3 All products manufactured with composite materials can be recycled by being crushed and reused as internal structures in manufacturing processes.

[0035] 31. Flexible solar panels can also be applied to manufactured structures, adapting to various surfaces and generating further cost savings. The vision involves transferring technologies that can be applied to containers used in the logistics transport of cargo and people.

[0036] 32. In composite containers, the unloading of agglomerated sugar would take approximately 30 minutes. By including PU (PIR) foam in the core of the walls, refrigerated wagons can be made and optimized with the installation of flexible solar panels to capture solar energy. This energy will power the evaporators and condensers for refrigeration; the excess clean energy will assist the locomotives, which are dual-fuel (Diesel), to generate electricity, making them more efficient with less diesel consumption and its harmful emissions.

[0037] 33. Each train train removes 386 trucks from the roads and is four times more cost-effective. This initiative not only boosts economic efficiency but also reflects a genuine commitment to environmental responsibility, aligning with the current demands of transportation operations.

[0038] 34. The composite, with its low weight, allows for a reduction of 12,000 kg in 100 / 120 units, resulting in various savings, such as in diesel consumption and pollutant emissions. Furthermore, the composite, despite being lighter than steel, does not compromise the necessary strength; it can be manufactured by pultrusion and / or infusion.

[0039] 35. Thermal insulation: Composites are naturally thermal, electrical, and static insulators. By using specific insulation in the core, we can develop refrigerated wagons, truck bodies, and containers.

[0040] 36. Chemical resistance: With high chemical resistance and flame retardant protection, composites have an average durability four times greater than steel. This is because steel tends to deteriorate with the transport of highly corrosive products, such as sulfuric acid SO3 (sulfur), fertilizers, and others.

[0041] INNOVATION:

[0042] 37. In general terms, the aforementioned product represents a solution with regard to a container for logistics.

[0043] 38. Abrupt mass reduction, thermal insulation, protection of commodities, thermal insulation, electrical, static, action of chemical agents, among others. 39. Composites are naturally thermal, electrical, and static insulators. By using specific insulation in the core, we can develop refrigerated wagons, truck bodies, and containers.

[0044] 40. With high chemical resistance and flame retardancy, composites have an average durability four times greater than steel. This is because steel tends to deteriorate with the transport of highly corrosive products, such as sulfuric acid SO3 (sulfur), fertilizers, and others.

[0045] 41. Among the main advantages of logistics containers are their low weight, being *4 less than the weight of steel, consequently saving transport fuel and reducing pollutant gas emissions; greater impact resistance, since the mixture of materials used to make the container increases its resistance; similarly, this resistance also increases with regard to material fatigue and corrosion; it is a thermal and electrical insulating material with a low expansion factor; it can be used to transport various types of materials and cargo, whether liquid or solid; it is made from recycled material.

[0046] 42. The hatch is lighter, easier to handle, with an estimated weight of 8.5 kg, has greater durability, is not subject to chemical attack, and does not corrode due to the composition of the materials. It is produced with recyclable materials, does not oxidize, does not react with transported products, and is easy to maintain and clean. It provides a reduction in accidents, since the opening effort is less, with an estimated weight of 4.25 kg, when compared to the weight of steel (30 kg), the injury if the hatch closes on the worker is considerably less than the accident caused by the impact of steel.

[0047] 43. This innovative approach not only meets the demands of efficiency and sustainability, but also redefines the performance and functionality standards of railcars, especially those intended for the transport of refrigerated products, with railcars featuring flexible solar panels on the roof to power the machinery, and excess energy assisting the locomotive engines, which are dual-fuel: diesel and electric, making them more sustainable.

[0048] 44. The change in the wagon material reduces the transport weight, which has a direct impact on carbon dioxide (CO2) emissions; that is, for every liter of diesel burned, an average of 3.2 kg of CO2 is emitted. By reducing the weight, gas emissions are reduced, thus decreasing the environmental impact caused by freight transport. (From CO2 reductions) 2with an average emissions factor of 3.2 for each liter of diesel burned, resulting in a reduction of 12,000 x 120 wagons = 1,440,000 less mass consumption and thousands of emissions.

[0049] 45. Option to coat wagons and tippers with a layer of composites for thermal insulation and protection against chemical aggressions – an Achilles' heel in the transport of sugars and other commodities, where it takes 6 hours at the port to unload steel. Besides reducing environmental impact, landscape alteration, contamination of groundwater, soil and air, and worst of all, in the steel industry where the impact is gigantic, polluting much more.

[0050] 46. ​​This is a unique, exclusive and innovative product, highly reliable and recommended for use in the safest transport of cargo, and will certainly be a major differentiator for the sector it is intended for.

[0051] DESCRIPTION OF THE STATE OF THE ART:

[0052] 47. During the development of the aforementioned product, numerous studies were conducted to identify the existence of any prior or related products. However, these surveys did not reveal the existence of any other product with the same predominant technical or functional characteristics.

[0053] 48. The search found processes that superficially mention the combination, in whole or in part, of the words "logistics," such as PI07163991, BR2020140226643, BR1020200203711, and US5344700. However, these processes describe simpler products with arrangements containing only one polymeric material or a constructive arrangement in the shape of a wagon, compositions different from that claimed in the present patent application.

[0054] 49. Additionally, the searches conducted did not reveal a system that, besides increasing the safety of cargo transportation, is also capable of generating electrical energy for locomotion using a different material composition.

[0055] 50. Given this need and commercial opportunity, the aforementioned product was created, more precisely a container for logistics, whose function is to increase the safety of cargo transportation, whether in liquid or solid form. 51. Therefore, in accordance with article 8 o Based on Industrial Property Law No. 9.279 / 96 and all aspects presented in this report, the subject of this patent application deserves protection as an invention privilege, which is hereby requested.
