Descriptive report of the patent for PACKAGING IN CORRUGATED CARDBOARD WITH RECYCLABLE OR BIODEGRADABLE THERMAL INSULATION

Field of the Invention:

[001] The present invention patent corresponds to a structure formed by a recyclable and or biodegradable insulating material (1) and attached or not to a substrate (2) and fitted to a corrugated box (3). It is inserted in the packaging field as a sustainable alternative to thermal boxes made of plastic and EPS. It is an innovative product made with recyclable or biodegradable materials, consistent with the current environment policy, and comprising a folding structure, reducing the volume for transport and storage.

State of the art:

[002] Currently on the market, many of the options available to accommodate and conserve food, beverages, pharmaceutical products, among others, are made mostly of materials such as expanded polystyrene (EPS), the famous Styrofoam, which has a high cost recycling process , causing the amount of waste produced by this material to increase, thus causing severe damage to the environment.

[003] In addition to environmental damage, consumers and carriers face several problems regarding the transport and storage of thermal boxes made of EPS (Styrofoam), as these occupy large volumes in cubic meters, since the product is stored in its form final structural.

[004] Today on the market there are also models of thermal boxes that use different materials, such as polyethylene, however these materials provide a very high cost for their production, which is the result of several process steps to obtain the final product, therefore raising the cost to the consumer.

[005] Regarding patent databases, document MU 8502405-8 U (Constructive provision introduced in a thermal box for

2/11 transportation of products in general) as a proposal for a thermal box to pack and transport cold or hot elements, however this product has four distinct parts and one of them is made of injected polyurethane, a material that has a difficult disposal for presenting volatile substances and difficult recycling, since they are thermoset plastics and their fragments cannot be melted and melted again to be used in a plastic material of the same type.

[006] Sonoco ThermoSafe products, developed by the company Sonoco, available at: https://www.thermosafe.com/, can be cited as a proposal for storage and transportation of products that require temperature control. However, its solutions include Expanded Polystyrene or Polyurethane boxes - whose recycling process is expensive, in addition to using various items to maintain the temperature.

[007] The project of the company Cascades, available at: http://emballage.cascades.com/ContenantsSpecialises/contenants-thermofrais/#middle, whose PO box and laminate meets some requirements for temperature control can also be mentioned for storage and transportation of products. However, its thermal element does not guarantee total temperature conservation, whose honeycomb structural shape ends up allowing the temperature to escape more quickly and unevenly.

[008] Cooler Coolest can also be mentioned, available at: https://www.kickstarter.com/projects/ryangrepper/coolest-cooler-21st-century-coolerthats-actually/description, a thermal box for drinks and food created by Ryan Grepper, who invested in technology to add some other features that facilitate the consumption of food and drinks. In addition to having polystyrene as a raw material, and other materials that are harmful to the environment and difficult to recycle, it has its sale directed only to the camping and related sectors.

3/11 [009] There are several boxes of high density polyethylene, widely used for temperature control on several occasions. But it uses a lot of stacking space, in addition to not being biodegradable.

[010] The Big Shipper packaging, from Grupo Polar, available at: http://www.grupopolar.com.br/polartecnica/big-shipper/, which uses corrugated cardboard combined with Expanded Polystyrene, serving all segments that need temperature control. However, it uses polyurethane in its composition (not biodegradable) and has an assembly procedure that uses many aggregated items.

[011] Sofribox packaging, from Sofrigam, available at: http://www.pharmaceutical-technology.com/features/featuresofrigam-cool-packagingpharmaceuticals-save-lives/, has a long temperature control capacity. But, it has in its composition, high density rigid polyurethane sheets, being a material harmful to the environment, difficult to recycle.

[012] Cool Box, developed by Marketing and Logistics Technology students at Faculdade Anhanguera-MG, available at: http://www.webarcondicionado.com.br/estudantes-criam-caixa-termica-ecologica-abase-de -polyurethane, is considered an ecological, practical and inexpensive option for temperature control in product storage. However, it is handcrafted and its production on an industrial scale is not possible. Another factor is the use of polyurethane as a raw material, which ends up limiting its recycling, even though this material has already been reused from other products, such as air conditioners.

It is manufactured from waste conditioned. Use of polyurethane as thermal insulation. Use of recyclable and / or biodegradable materials.

Demand of the invention:

[014] From the problems mentioned, an opportunity to develop a foldable thermal box that meets the physical requirements for thermal insulation, which can bring an environmentally friendly alternative, with industrial production and which is viable for storage and transportation, can be identified of the same. The distribution, manufacturing and commercialization sectors of products with demand for temperature control, in addition to the final consumer, demand corrugated cardboard packaging with biodegradable and or recyclable thermal insulation.

Technique Description:

[015] The corrugated cardboard box with thermal insulation is comprised of two parts, the first being an external box (3) produced with corrugated cardboard sheet, which may vary in shape, dimension and model (as the examples in figures 11 and 12); preferably composed of two layers in kraft or recycled paper and a core, which may or may not receive water repellent treatment where the cardboard is waterproofed on the inner and / or outer layer and / or core, with Coob from 04 to 30g / m ² through a resin acrylic, completely recyclable, which can be applied in the corrugator process, thus allowing resistance to moisture, for later folding and assembly in the user's environment, reducing the volume in stock and transport since it will be transported from

7/11 flat shape; it can also be shaped like (figure 18) (8) with a cover (9) and closing latches (10).

[016] The second part, which will be internal, comprises two production models, the first of which is formed by an impermeable substrate (2), which receives a coupling made of biodegradable insulating material (1), which is a rigid polyurethane foam that can be from castor oil, cassava starch or coconut fiber, which will guarantee temperature stability in the transport of products with thermal insulation needs, being completely biodegradable, having its dimension defined according to the structure of the outer box (3 ) and the temperature to be maintained (as in the examples in figures 11 and 12) in the second production model, the internal structure of the box composes in addition to the internal element of corrugated cardboard (which has a water repellent treatment against moisture absorption becoming hydrophobic). Pet wool plates (figure x) are used to replace the waterproof substrate and rigid polyurethane foam. The assembly of the inner box with pet wool includes to the thermal plates of pet wool (figure 12) the internal element in corrugated cardboard (figure 14) and (figure 15); the thermal insulation plates on the bottom and sides are fitted and the pet wool is protected by an internal corrugated cardboard box, which is then fitted to the external corrugated cardboard box (figure xx), finally placing the internal cardboard cover with the pet wool.

[017] The assembly of the inner box comprises its planning (figure 2), with the lid directed upwards; the fold after the second plate (figure 3); the fold after the third plate, having this third as the base of the box (figure 4); the folding of the adjacent substrates from the axes formed by the base of the box (figure 5). With the realization of the folds (figure 6), the flaps are directed in front of the left (figure 7) and right (figure 8) side walls in a crossed direction. After assembly, the box (figure 9) is ready to be inserted in the outer box (3) (figure 1).

[018] The thermally insulated corrugated packaging, after use, is fully recyclable or biodegradable - since it is biodegradable

8/11 it produces a much lower environmental impact than other related materials, and can also be used as fertilizer or compost. Pet wool, on the other hand, comes from recycled and recyclable pet products in technologies already known in the market, it is a product developed from recycled plastic bottles, it is made of 100% polyester, and it is also hypoallergenic.

[019] Pet Wool is made with very light polyester fibers that undergo a compacting process at low temperature (160 ° C to 180 ° C) and pressure. Water and any type of resin or any volatile component is not used, which guarantees much greater stability and maintains the acoustic and thermal behavior for an indefinite period, in addition to being ecologically correct and sustainable. It has advantages of lightness, ease of handling, reduces transportation costs, as it can be compacted without losing its original characteristics, does not loose fibers, does not irritate the skin and because it is inert, does not proliferate fungi and bacteria. It does not absorb water or moisture, so it does not mold.

[020] Pet wool is easy to store due to its high compaction power. Due to the high resilience index, the blanket returns to its original dimensions immediately, when the bales are opened and, if folded, does not break.

[021] Ecologically correct, pet wool is recyclable, non-allergic, non-carcinogenic, does not pose a risk to health and is produced through sustainable processes that contribute to the preservation of the environment.

[022] Every 1,000 m ² of pet wool (50 mm and 10 kg / m ³ ) approximately 17,000 PET bottles (500 ml water bottles - 15.5 g each) are removed from nature. It has different thicknesses (from 5 to 100 mm), different densities (from 5 to 35 kg / m ³ ), white color and can be dimensioned according to each project. It is an excellent thermal and acoustic insulator, which was developed to replace traditional insulators such as glass wool, rock wool and polyurethane, which are expensive, harmful to health and the environment.

[023] One of the insulating components (1) of the corrugated cardboard packaging with thermal insulation, object of the present claim, is the rigid polyurethane foam from castor oil, also comes from a renewable source,

Petition 870160078406, of 12/22/2016, p. 15/32

9/11 because they are polyols based on natural oil, which replaces raw materials of petrochemical origin.

[024] The packaging in corrugated cardboard with biodegradable or recyclable thermal insulation aims to replace packaging in expanded polystyrene (EPS), better known by the trade names Styrofoam (which is a registered trademark of Knauf Isopor Limitada) and Styrofoam (brand of the Brazilian company Estiropor Nordeste Indústria e Comércio Limitada). It is estimated that the Styrofoam takes about 150 years for its degradation and even though it is recyclable, it is not viable due to the high cost of the processes since its composition is 98% air; and for this reason, cooperatives are not interested, since it is a low density product and takes up a lot of volume and high transport costs. When disposed of incorrectly, it causes a series of damage to nature taking up a lot of space in landfills and dumps, which are saturated and could be destined for other waste. Because it decomposes very slowly and is impermeable, it harms the soil and prevents water from entering, and is still mistaken for food by animals that ingest the microplastic. The thermal insulation sheets from there have a insulation coefficient similar to styrofoam and can be 100% recyclable and contribute to the environment, since they remove from nature a material that would take more than 100 years to decompose and that are randomly discarded, causing serious problems to cities and nature to recycle and use as raw material. Insulations based on castor oil, cassava starch or coconut fiber, have the same density and structure as the Styrofoam, with similar insulation coefficient, in addition to being a non-toxic material.

OBJECTIVE OF THE INVENTION:

[025] The present invention patent has the objective of avoiding the inconveniences of the materials described above, presenting for this an ecological and innovative solution since it allows the transport of products guaranteeing the thermal insulation, its safety, stock and transport in the empty state flat.
