Abstract

DISPOSITION INTRODUCED IN RIGID PLASTIC TRAY FOR CULTIVATION OF SEEDLINGS IN BIODEGRADABLE PAPER CONTAINERS.

1. 1) “ARRANGEMENT INTRODUCED IN RIGID PLASTIC TRAY FOR CULTIVATION OF SEEDLINGS IN BIODEGRADABLE PAPER CONTAINERS”, tray (100) for cultivation of seedlings in ‘paperpots’ (PR) formed by a plurality of receptor cells (110), being a total of thirty-two, which are aligned in rows and equidistant, as well as interconnected at the top in a rectilinear base (111) of rectangular shape with rounded vertices; characterized by the tray (100) being made of recyclable plastic and having a rectilinear base (111) bordered by a contour skirt (111A) joined to the body of the tray (100) by a pattern of reinforcing ribs (111b) that develop from the lower face; The skirt (111b) has a peripheral wall with an enlarged height (t1) and greater width (l1) in the smaller extreme portions, forming flaps (AB); each receiving cell (110) has a slightly conical shape with a quadrangular outline of rounded vertices (110a) and peripheral walls (110b) deformed by sinuous recesses (110c) that extend longitudinally in each cell (110); interspersed with each sinuous recess (110c) are angled projections (110d) of trazezoidal shape that begin near the nozzle of each cell (110) and end at the base (110e), which, in turn, is flat with a central opening (110f) of circular shape from which a radial pattern of ribs (110g) develops with convex upper faces; In the opening of each cell (110), diametrically opposed ‘U’ shaped cutouts (111d) are made in the free sections of the straight base (111), and ‘V’ shaped cutouts (111e) are made in the walls of some cells (110); said cells (110) are connected to each other by links (110h) that develop from the lower face of the base (111) and are arranged between the peripheral walls (110b) extending to above the median portion of each cell (110).

Description

TECHNICAL FIELD [001] This utility model relates to an arrangement introduced in a rigid plastic tray for growing seedlings in biodegradable paper containers widely known as ‘paperpots’ where, notably, said innovative tray is produced in recyclable plastic and is designed to accommodate ‘paperpots’ up to 50 mm in diameter and 150 mm in height and presents an innovative construction such as the set of cells interconnected by links that promote greater structural resistance for handling, as well as, each cell has a base provided with multiple radial slits that enable the aeration of the ‘paperpots’ for the growth of the seedlings, in addition to including angular protrusions for centering the ‘paperpots’ and other constructive additions that guarantee improved seedling production. HISTORY OF THE TECHNIQUE [002] Conventional rigid plastic trays for growing seedlings in ‘paperpots’ have characteristics that make them suitable for the initial development of seedlings and, in general, are molded pieces of plastic material with individual cavities called cells designed to house and support the ‘paperpots’. [003] The shape of the cells can vary such as circular, square or rectangular and the depth must be sufficient to accommodate the ‘paperpot’ and the root system of the developing seedlings. [004] Despite advances in the market, there are still some shortcomings in conventional trays that can negatively affect the quality of seedling cultivation in paperpots, impacting costs and production, such as conventional trays that do not usually provide a sufficiently robust structure. As a result, it is common for the tray to bend or warp during use, especially when handling the paperpot cells. [005] Another drawback lies in the fact that conventional paperpot trays have little or no area dedicated to attaching information such as identification labels. Such labels are usually stuck anywhere on the tray, usually on the cups or cells, remaining curved by their shape and resulting in difficulty in reading and identifying this information. [006] Another drawback lies in the fact that conventional paperpot trays have cells without walls with longitudinal deformations that stabilize the paperpots and without openings that facilitate the removal of these paperpots. State of the Art Analysis [007] Research conducted in specialized databases revealed documents relating to seedling trays, such as document no. BR 20.2017.009091-0, which deals with a seedling tray containing multiple cavities that serve as slots for transporting seedling tubes. These tubes have a rectangular pyramidal shape and contain several ribs designed for a better fit in the tray, allowing seedlings to be transported in various arrangements without the risk of damage. [008] Document No. BR 10.2019.022438-0 discloses trays for seedling propagation processes, more specifically, for housing biodegradable tubes, which have a circular shape; the intelligent tray consists of a cluster of cells that follow the circular pattern of the biodegradable tubes, each cell has a specific inclination for easy entry and removal of the tubes, and they have air openings at the ends of the lower side and lower base, which serve to aerate the roots and drain excess water. The cells have veins facing inwards, which serve to guide the seedling's roots, preventing them from growing out the sides and/or upwards; they present innovative characteristics that assist in capturing and directing irrigation to the seedling, aiding in its development and growth. [009] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the object now improved, thus guaranteeing that it meets the legal requirements for patentability. FUNCTIONAL IMPROVEMENTS [010] The functional improvement consists of forming a rigid plastic tray for growing seedlings in ‘paperpots’ whose cells interconnected by connecting links provide structural reinforcement associated with the provision of angular protrusions for centering the ‘paperpots’ and, consequently, reducing the contact area, promoting better air circulation and encouraging aerial pruning, preventing root entanglement. Advantages Obtained [011] One of the advantages of the tray in question lies in the fact that the peripheral edge has a larger area for receiving identification labels, allowing control over the types of ‘paperpots’ transplanted. [012] Another advantage lies in the fact that the cells of the tray in question are arranged in a format that facilitates transport and optimizes the storage area, resulting in cost reduction, in addition to the fact that when fully loaded with 32 ‘paperpots’, they can be stacked on top of each other without damaging the ‘paperpots’, making the management and automation of the nursery more efficient. [013] Another advantage lies in the fact that the tray offers versatility of use, since it can be used in various
