Device for plant boards

The present invention relates to a device in plant boards with cavities for peat pots for growing of plants.

Several plant board genera are already known where soil is filled directly into the cavity of the board becomes, as well as plant boards for peat pots, a growth agent contain. In the latter case, laborious work is required to set large quantities of peat pots into the boards. Peat pots stacked one inside the other also have the

Disadvantage that they break easily when stacked have wedged, although the wall thickness of the pots is greater than necessary for the growth of the plants. at For several plant board types, the pots are also next to each other without dividing walls. Roots from a pot can thus grow into adjacent pots, the pots when planting out with the risk of destroying both the pots and the plant roots need to be torn apart.

The previously known boards are also so expensive that they have to be used repeatedly, which is more work To cancel it means.

The purpose of the present invention is thus primarily to provide a device in plant boards, which the previous disadvantages eliminated. This is achieved in such a way that the board consists of thin foil material which surrounds the pots is vacuum formed. The film is vacuum-formed around the pots at the place of manufacture so that the pots are already handled before any handling are protected. Protected by a thin plastic film, the pots can be designed with a smaller wall thickness than before, which saves material; and a plant board formed from foil can have the desired number of peat pots, i.e. one for Handling, for example, in nurseries contain an appropriate number · The plant boards with pots are thus automated Manufactured very inexpensively at the place of manufacture, and several boards can be stacked one inside the other without the risk of wedging, as each The outside of the pot is covered by the plastic sheet of the board, whereby the sheet not only protects the pots, but also protects them from being removed one board each from the stack made easier.

The boards can be quickly exposed at the cultivation site and the plastic film on the outside of each pot prevents that roots grow from one pot into other pots. However, the roots can grow through the wall of the pot and the plant receives a firm root lump, which is particularly important when using a loose growth agent such as sand soil.

The device according to the invention is particularly suitable for growing plants with a long cultivation time, such as forest plants and ornamental shrubbery

Because the pots are surrounded by a thin film material, for example an appropriate plastic film, In fact, the pots and the foil work together.

Material, in that the pots stiffen this material and a very thin film material can thus be used.

The invention is characterized by the features specified in the claims and is explained below with reference to the drawing explained in more detail, whereby

1 shows a perspective embodiment of a inventive plant board and

FIG. 2 shows a section along the line II-II in FIG. 1 represents.

In FIG. 1, a plant board 1 is shown as an exemplary embodiment shown, which has sixteen pots 2. If desired, can however, the boards contain several pots. The board 1 consists of a thin plastic sheet that is vacuum formed directly over the pots is. The pots are thus tightly surrounded over a substantial part of their height and held in the board, whereby the board without special caution can be handled. The vacuum coating of the plastic film over the pots takes place immediately after the Manufacture of the pots in such a way that they are, so to speak, immediately protected against damage. Using the phrase "board" are in this context also strips with curd and contiguous Ribbons meant with pots. As mentioned above, the boards can be stacked one inside the other, with the thin plastic covering attached to the The outside of each pot prevents wedging. If boards are removed from a pile, the board is also lifted to itself, without pulling on the pot. The exposure of the pots in a nursery is also quick, because a large number of Curd can be handled in one hand. The development of the plants is, as already mentioned, satisfactory because the roots are firm Lumps of earth are collected and do not grow into pots butting against them. The pots can be easily removed when planting out by peeling off the thin plastic film with a simple movement. Since the plastic wrap is thin, the volume of waste becomes very low even with a large number of pots. The plastic material is said to be of the kind that is rapidly decomposed if the material is buried or can be burned without to emit toxic substances, the pollution of the environment is reduced to a minimum.

FIG. 2 shows a section along the line II-II in FIG. 1. For the sake of clarity, the strength ratios are greatly exaggerated. The plastic film 1 is with a thick, drawn line

indicated and the pots are shown hatched. The vacuum drawing the plastic film 1 does not need any further description / since such a wrapping of all kinds of objects is common today is known.

From Fig. 2 it can be seen that when stacking several boards with pots always a thin plastic layer between each two pots stacked one inside the other, which makes it easier to separate the boards.

With regard to the drainage of excess water and thus the plants in certain forms of underwatering can suck in water from below, the plastic film 1 should be perforated at the bottom of each pot 2 as indicated at 3 in FIG.

In addition to the above-mentioned advantages of the present invention, the plant boards according to the invention enable a simple and practical way of transporting large quantities of pots without risk of damage and with the least amount of loading and deletion time.

For certain areas of use, it can be advantageous that the upper edge of each pot is slightly over the plastic film in the Plant board 1 protrudes, among other things, so that the pot with root clumps can be more easily grasped when planting out. This is in Fig. 1 shown.

The edges of the pot, however, are better protected when the plastic film extends to the edge of the pot, as shown in FIG.

In addition to the advantages already mentioned, the plant board according to the invention enables a simple and practical one Transporting and handling large quantities of pots without risk of damage and with the shortest loading and unloading times, whereby at the same time you have a more free choice of material thicknesses.
