Abstract

Improved disposable tray for plant cultivation consisting of a square piece (1) with a perimeter rim (10) and tray body (11) in which a plurality of cultivation containers (12) are generally configured in the form of a trunk- pyramidal or inverted conical trunk equal to each other that are open at the top and extend downwards, distributed adjacent to each other uniformly forming a grid, characterized by: -the square piece is made of thermoformed polyethylene terephthalate; and -a reinforcing support (2), also based on thermoformed polyethylene terephthalate, is provided, in the form of a quadrangular plate that is fixedly attached in one piece to the lower ends (120) of the culture vessels, so that the set consisting of the square piece and the reinforcing support has increased mechanical stability and rigidity.

Description

Disposable tray perfected for growing plants.

Field and prior art

The present invention has application in the agriculture field to provide cultivation trays also called seedlings for seedling development intended for subsequent transplantation that are manufactured based on injected plastic materials.

These trays are made up of one piece. quadrangular with a perimeter flange and central body in which a plurality of culture vessels are configured generally of trunk-pyramidal shape or trunk inverted conical equal to each other that are open from above and that extend downward, distributed adjacent to uniform way forming a reticle.

It is known to manufacture this type of trays with various non-porous rigid thermoplastic materials that result too heavy for occupational health and safety standards. In addition, these types of plastic materials are not recyclable and therefore both pose a heavy burden on the environment when should be removed after use.

To solve the aforementioned problems of weight and environmental pollution, the use of seedbeds based on expanded polystyrene that although they are much lighter, have disadvantages derived from porosity of the material, since they are easily penetrated by the system root of the seedlings which hinders their extraction and also they are very conducive to the development of fungi that must be treated with fungicides, both the growth of seedlings impaired and that constitute a source of contamination after utilization.

To solve these problems have been proposed the application inside the culture vessels of a non-porous coating which is unacceptable from the point of view of manufacturing costs. It would also be possible to think in an increase in the density of the polystyrene material expanded, but this would lead to a high weight that neither It is acceptable according to the recommended safety standards and occupational hygiene

Object of the invention

The present invention raises the development of a culture tray or seedbed of the type indicated on a principle of reduced weight based on a plastic material susceptible to recycling and also have sufficient mechanical stability to allow transport when loaded with the crop peat and the seedlings in development.

According to the invention this task is solved according to the invention from a tray consisting of a quadrangular piece with a perimeter flange and tray body in which are configured a plurality of culture vessels usually trunk-pyramidal or trunk inverted conical and equal to each other that are open from above and that extend down, adjacently distributed so uniform forming a grid, which is characterized by how much:

-

the piece quadrangular is made of polyethylene terephthalate thermoforming; Y

-

a reinforcement support, also based on polyethylene terephthalate thermoforming, in the form of a quadrangular plate that is attached fixedly forming a single piece at the lower ends of the culture vessels,

so that the set formed by the piece quadrangular and reinforcement support presents stability mechanical and stiffness increased

According to an additional feature of the invention, the connection between the square piece 1 and the support of reinforcement is done by a joint thermo-soladada and / or by gluing by means of a adhesive material

Brief description of the figures

Other features and advantages of the invention will result more clearly from the following description made with the help of the attached drawings referring to an example of execution non-limiting of the invention, and in which

Figure 1 illustrates a perspective view partially sectioned from a culture tray according to the invention.

Figure 2 shows a side elevation view of the tray according to the invention.

Detailed description of one embodiment

As shown by the figures, the tray crop consists of a quadrangular piece 1 that has a flange 10 formed around a tray body 11 in which a plurality of culture vessels 12 are configured, by example, trunk-pyramidal or inverted trunk-conics equal to each other than they are open at the top and they are distributed uniformly and adjacent to each other formed a structure by way of reticle.

According to the invention, it is planned to provide a reinforcement support 2 in the form of a side-sized plate similar to those of tray body 11 that is fixedly attached forming a single piece at the lower ends 120 the culture vessels 12. In this way, the tray assembly and support has increased mechanical stability and rigidity that allow to support the load of the tray with the substrate of crop and seedlings that are developing in it.

According to the invention, the union of the Foursquare piece 1 and reinforcement bracket 2, is done through thermo-welding or by gluing by adhesive material

As mentioned earlier, both the piece quadrangular as the reinforcement bracket are manufactured based on thermoformed polyethylene terephthalate for ensure reduced weight and easy recycling of the tray and Support once they have been used.

Enough that the invention has been described, it only remains to point out that the realizations derived from changes in shape, dimensions and the like, as well as those resulting from a routine application of the above disclosed shall be considered included in its scope so that the invention so It will only be limited by the scope of the following claims.

Claims (2)

1. Disposable tray perfected for plant cultivation constituted a quadrangular piece (1) with a perimeter flange (10) and tray body (11) in which a plurality of culture vessels (12) are generally configured in a trunk-pyramidal shape or inverted conical trunk and equal to each other that are open from above and that extend downward, distributed adjacently evenly forming a grid, characterized in that:

-

the piece quadrangular is made of polyethylene terephthalate thermoforming; Y
