Description

Descriptive Report of the Invention Patent for "CONTAINER FOR AGRICULTURAL DEFENSIVES".

[0001] The present invention relates to a container for containing liquids, and particularly for containing agricultural defensive products, such as pesticides. Description of the State of the Art

[0002] The use of containers, bottles, and drums for the production, containment, and transportation of pesticides or other agricultural pesticides is known in the state of the art. Furthermore, the use of PET (polyethylene terephthalate) in containers with volumes up to 2 L is also known.

[0003] Document BR102019025488-2 is an example that describes a container for agricultural pesticides using PET as a material. However, containers made of PET have limitations in terms of internal volume and shape, given the mechanical strength limits of this material. Therefore, the container in the aforementioned document has a reduced volume compared to drums using other mechanically more resistant materials, such as HDPE COEX. Compared to the present invention, the container in the aforementioned document presents important differences, such as a lower weight, cylindrical shape, no concentration of material at points of mechanical stress, and reinforcements with recesses arranged differently.

[0004] PET containers currently on the market for other uses, such as food or home care, also have low grammage values ​​(approximately 85g-95g). This grammage is significantly lower than that of the present invention. Consequently, these PET containers have much lower chemical and mechanical resistance.

[0005] Traditional drums made of HDPE / COEX They weigh approximately 250g or 300g. These familiar drums are manufactured by coextrusion with a solvent-resistant barrier used in the agrochemical market. The presence of these barriers, typically made of polyamide or nylon, prevents the HDPE / COEX drum from being recycled, which is not the case with PET containers.

[0006] Therefore, the state of the art presents a problem that needs a solution. Bottles using recyclable PET material have low volume (less than 3L) due to their low mechanical and chemical resistance, in addition to their reduced weight (less than 100g). On the other hand, larger-volume drums use HDPE COEX, resulting in a product that cannot be recycled. Furthermore, known drums use high weight, which reduces manufacturing efficiency by using an excessive amount of material.

[0007] Therefore, there is no state of the art container for agricultural pesticides that can be recycled, has a volume greater than 3L, reduces excessive use of material and has high mechanical and chemical resistance. Objectives of the Invention

[0008] A first objective of the present invention is to provide a container for agricultural pesticides with recyclable material.

[0009] A second objective of the present invention is to provide a container for agricultural pesticides that has high mechanical and chemical resistance.

[0010] A third objective of the present invention is to provide a container for agricultural pesticides that has a low manufacturing cost.

[0011] A fourth object of the present invention is to provide a container for agricultural pesticides that has structural recesses to increase mechanical resistance.

[0012] A fifth objective of the present invention is to provide a container for agricultural pesticides that has a higher weight than small bottles and lower weight than 5L drums currently on the market.

[0013] A sixth objective of the present invention is to provide a container for agricultural pesticides that presents a concentration of material in places of greatest mechanical stress. Brief Description of the Invention

[0014] The invention relates to a container for agricultural pesticides, comprising an upper portion, an intermediate portion, and a lower portion, wherein the upper portion and the intermediate portion are intermediated by an upper contour recess, and the intermediate portion and the lower portion are intermediated by a lower contour recess, wherein the intermediate portion comprises recesses, wherein the container is composed of polyethylene terephthalate (PET). The recesses may be arranged transversely to the container.

[0015] The container may have an internal volume of 2.5 L to 10 L and a mass of 100 g to 200 g. The upper portion may comprise a mouth and a shoulder, the shoulder having upper recesses. The middle portion may have a rectangular cross-section with rounded corners. The lower portion may have lower recesses. Brief Description of the Drawings
