FR2692200A1 - Producing decorative sheets with plants - Google Patents

Abstract

When the plants or parts of them (2) are positioned on the flexible sheet (1) and covered with the two outer sheets, the whole assembly is welded together under pressure. The plants are firstly subjected to a pressure of approximately 10 kgs/cm2, and then to a drying process at an ambient temp. of approximately 25 deg. C. The welding of the two outer sheets takes place at a temp. of 165 deg. C and under a pressure of at least 20 kgs/cm2. The flexible foil sheet is of plastic, and the disinfection medium used for the plants is acqueous formaldehyde.

Description

PROCESS FOR MANUFACTURING LEAVES ORNAMENTATED WITH PLANTS
The invention relates to a method of manufacturing ornamented leaves of natural plants used to form, for example, a table.

It is obvious that we already know of means of sticking a natural leaf or branches of plants on sheets of paper, cardboard and the like, and we also know that after a certain time the leaf or the branches of a plant deteriorate because they have not been treated properly.

With the method of the invention, we manage to overcome the aforementioned drawbacks and, moreover, this method is very easy to practice with elements or instruments that are simple to handle.

The method of the invention comprises the following steps
- Use a flexible sheet.

 - Harvest and select the part or parts of a natural plant.

 - Subject the plant to a pressure of approximately LO kilos / cm2, then to a drying operation at an ambient temperature of approximately 25'C.

- Submit the plant to a bath in a disinfectant solution, for example formalin
- Glue the part of the plant on the face of the leaf.

 - Cover the assembly with two plastic sheets which are heat sealed at a temperature of i650C and at a pressure of at least 20 kilos / cm2, this temperature being that which is necessary to subject the plant to a sterilization operation.

In order to better understand not only the constitution but also the use of the process of the invention, we will give below a practical example of application of this process, represented by the attached drawings; wherein
FIG. t is an elevation view of the leaf with the glued plant obtained by the method of the invention,
Figure 2 is a sectional view on the axis II-II of the
Figure 1.

If we refer to the drawings, they represent the sheet 1 of a flexible material on one side of which is stuck a natural plant 2, after the latter has been subjected to a series of steps of the process of the invention.

The sheet with the plant stuck is placed on two transparent plastic sheets 3 and 4, and are heat sealed at a temperature of 165in and at a pressure of 20 kilos / cm2.

The sheet thus formed can then be framed if one wishes to make a table of it.

The nature of the invention, as well as the manner of putting it into practice, having been sufficiently described1 it should be pointed out that the aforementioned provisions are susceptible of modifications in detail insofar as these do not alter the Fundamental principle.

Claims (3)

 t. A method of manufacturing ornamented leaves of plants, characterized in that it consists in using a flexible leaf (1), in harvesting and selecting a plant (2) or a part thereof, in subjecting the plant to pressure about 10 kilos / cm2, then to a drying operation at an ambient temperature of about 2SeC, and to subject the plant to a bath in a disinfectant solution, to stick the plant on the face of the leaf; to cover the leaf and plant assembly with two opposite facing plastic sheets (3 and 4) which are heat sealed at a temperature of 165 ° C and at a pressure of at least 20 kilos / cm2, this temperature being that necessary to subject the plant to a sterilization process. 2. A method according to claim 1, characterized in that the flexible sheet (1) is plastic in nature and constitutes the support of the plant. 3. A method according to claim 1, characterized in that the disinfectant is formalin.
