Abstract

PROBLEM TO BE SOLVED: To obtain a container with high thermal insulation for growing plants by using natural textile fibers which are bonded to each other with a glue such as starch, thus can be relatively easily broken through by the roots in no need of repotting. SOLUTION: Natural textile fibers are bonded to each other with a warm water-soluble binder such as starch or polyvinyl alcohol or a thermally melting or dissolving binder such as polypropylene, and preferably the sheets are compressed to form the objective containers. Several different kinds of natural textile fibers, for example, flax, wool, cotton and the like are mixed, additionally used paper and waste card board may be admixed in small amounts.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has as its object a container for growing plants and a method for producing the same.

[0002]

2. Description of the Related Art Currently, the young (y
growing) plants or plants and packaging (pa)
A variety of different types of containers or pots for caking are known, said containers or pots being adapted to provide optimum growth conditions during all growing periods.

These pots are generally made of a plastic material such as PVC, polyethylene or polypropylene, wood fibers or press peat, or press cardboard.
d cardboard), metal, etc.

However, in the case of pots of plastic material, the roots of the plants cannot penetrate the walls of the pots during their growth, which results in "bundles".
g) ”, known as the root flexion (ro)
Ling up) and arrest of natural growth (stran)
of the plant, and further requires that the plant be unpotted prior to its planting or repotting in a large pot, and then removing and repotting several times during the growing period ( repo
t) which is inherently inconvenient due to the fact that recycling the pot is relatively expensive.

With regard to cardboard, cardboard, wood or prespie pots, on the one hand their low mechanical resistance to root pressure of the plants and on the other hand their low mechanical resistance to shock during handling and transport for,
For example, it is not possible to produce large pots equal to or greater than 2 liters, and this low mechanical resistance results in the survival survival of plants during their transplantation.
al), and they do not allow growth periods longer than about 3 months.

Finally, metal containers with walls with conduits rust under the action of water and fertilizers, and the walls are poor for thermal insulation.

[0007]

SUMMARY OF THE INVENTION The present invention provides a relatively large penetrability by roots.
y), with increased mechanical resistance, with good thermal insulation for plant roots, and with pot removal and control of soil mass around plant roots
It has the purpose of overcoming the various drawbacks mentioned above by providing a container which makes it possible to avoid l), saving time and facilitating the planting operation. While the container is further biologically degradable, it serves as a nutrient for the plant without ruining the environment.

DETAILED DESCRIPTION OF THE INVENTION A container according to the invention is a natural textile fiber interconnected by a binder composed of a heat-meltable or heat-meltable substance.
It is essentially characterized in that it is manufactured from a material composed of le fibers).

The process for producing such a material is to mix several types of natural textile fibers such as hemp, wool, cotton, etc. in well-defined proportions and chop them into the mixer inlet. On the other hand, a binder suitable for being homogeneously introduced into the natural fiber in the same form and in a predetermined proportion depending on the function of the desired composition is introduced at the other inlet of the mixer. Introduced, the mixture is then conveyed to an enclosure to melt or melt the binder and bond a variety of different natural fibers together. The material is preferably placed in the form of a sheet at the exit of the containment, then the sheet is precut and compression molded by known means such as hot pressing.
mped out) is preferred.

According to the invention, the binder used can be a heat-meltable binder, for example polypropylene, in which case the enclosure melts the polypropylene and binds the fibers together. An oven that brings the mixture to a temperature controlled to bind.

The binder used is also water soluble at certain temperatures, preferably above ambient temperature.
It may be a binder which is a able), for example a binder such as starch or polyvinyl alcohol, in which case the enclosure is a bath or an impregnating means.

Further in accordance with the invention, other natural prime materials such as waste paper, cardboard (cardboard)
For waste, wood waste, peat waste, etc. ensure that the amount of textile fibers present in the mixture itself provides sufficient mechanical resistance to impact and to root pressure of the planted container. It can be mixed with the textile fibers in a predetermined ratio such that

The sheet of material used to manufacture the container according to the invention must be sufficiently rigid to enable it to form a container that remains unchanged in shape and its thickness is A thickness suitable to vary depending on its mechanical resistance function and on the function of the contents of the bowl to be produced.

[0014]

Examples For the purpose of an example of a composition suitable for producing a plant container with a volume of about 2 liters, the following composition may be mentioned:

[0015]

[Table 1] Wool 25% Cotton 60% Tama linen 10% Polypropylene 5%

By passing a container made from this composition into the bath, for example fertilizers or phytosanitary products
Chemicals like or also mushrooms, bacteria,
Selected bacteriological, primordia (g, protozoa, etc.)
erm) or microbial products.

The container according to the invention can also be colored with a coloring agent which is non-toxic to vegetation and which is preferably biodegradable.

It will be appreciated that the present invention is not limited to the above description and that many variations can be accommodated without departing from the scope of the invention.

Claims (6)

[Claims] 1. A container for growing plants, characterized in that it is formed from a material composed of natural textile fibers bound together by a binder of starch. 2. The container according to claim 1, characterized in that the textile fibers are selected from hemp, wool, cotton or other fibres. 3. Other natural base materials, such as waste paper, cardboard (cardboard) waste, wood waste, pressed peat waste or the like, the amount of textile fibers present in the mixture is, in itself, impacted. And is mixed with textile fibers in a predetermined proportion to ensure sufficient mechanical resistance to the root pressure of the plant introduced into the container , Claim 1
The container described in. 4. Hemp, wool, in a well-defined ratio
