The present invention relates to a method of making an article comprising a press-dried plant and to an article produced by the method. More specifically, the present invention is to quickly dry the collected plants, such as flowers, and then attach the dried plants to the surface of cards, sheets, general household appliances, furniture, etc., the shape, color or contour similar to that of living plants The present invention relates to a process for the manufacture of articles which can be stored by retaining the dried plants without discoloring for a long time.

Articles containing compression-drying plants (hereinafter referred to as compression-drying plant articles) are for example compression-drying in the design of labels, cards, bookmarks, postcards, covers of postal folders, furniture, tableware, clothing, and upholstery. It can be widely applied by attaching plants thereon. The press-dried plant article according to the present invention may itself be a new article, or it may be said to have added value in terms of design and intrinsic functionality.

Conventional methods of making press-dried plants generally consist of placing the plants between paper sheets or fabric sheets and pressing them. Dehydrating agents, such as silica gel, can also be placed under paper sheets or fabric sheets.

Next, the dried plant is quickly placed on the surface of the card or sheet to prevent discoloration of the plant, and then the product is attached by attaching a self-adhesive tape to the card.

In addition, tablecloths or decorative frames can be made by placing dried plants on a cushion sheet and covering them with hard plastic plates or plate glass to hold the dried plants in between.

In the conventional method of using only paper or fabric, or placing silica gel under paper or fabric, the dehydration efficiency is relatively low or time-consuming for dehydration because the plant is not close enough to silica gel. Thus, during the assembly process or while the press-dried plant is in the product, bleaching often occurs in a relatively short period of time.

Moreover, in the assembly step of the conventional method, the dry plant must be quickly placed on the item to be decorated and covered with self-adhesive tape, and the time taken between the end of the drying step and the adhesion step must be short. Even if the plant is dried with a desiccant, decolorization occurs because of oxygen in the air when the dried plant is stored for several months. Therefore, the flowers collected at the best bloom time should be commercialized only a few days after drying.

In general, many plants are collected in the spring when a wide variety of plants are in full bloom, and few plants are collected in winter, so the amount of products varies considerably with the seasons. Since it is difficult to collect all plants in spring, the ratio of collected plants to commercialized plants is relatively low.

Moreover, even if the dried plant is fixed to the surface of a sheet or a card by attaching a self-adhesive tape, air remains around the surface of the sheet between the sheet surface and the tape, and the shape or circle of the plant is distorted, resulting in reflection or refraction of light. It causes an unnatural appearance, deteriorating the beauty of the plant. In addition, there also arises a problem that the residual air causes dry bleaching. In a tablecloth or decorative frame in which a dry plant is placed on a cushion sheet and covered with a hard plastic or glass plate, the attempt is made because the rigid (three-dimensional) appearance caused by the delicate irregularities of the plant is ruined and its aesthetics are also degraded. Become limited.

The object of the present invention is firstly to provide an article comprising a compressed-dried plant in a state having a color and shape similar to that of a living plant, and a method capable of maintaining such a state for a long time and an article produced by the method. To solve the problems with conventional methods for producing press-dried plant articles and articles produced thereby.

Secondly, an object of the present invention is to be able to store dry plants for a long time, to manufacture and ship dried plant products regardless of the flowering period or collection time, and to increase the ratio of collected plant-to-product. Thus, according to the invention the commercial value of the press-dried plants can be significantly increased.

According to the present invention, a method for producing an article comprising a press-dried plant is provided, which comprises the following steps. That is, a gathering plant, such as a flower, is sandwiched between two flexible sheets, or between one flexible sheet and one cushion sheet, with a desiccant, in particular a strong drying agent such as anhydrous magnesium sulfate, anhydrous calcium chloride or a mixture thereof.

The plant is dried under pressure while heating in a dry atmosphere such as a room or a chamber. The completely dried plant is stored in a bag of gas barrier material impregnated with the above-mentioned strong desiccant and oxygen absorbent such as iron powder.

This plant is taken out of the bag immediately before making the article accompanying the press-dried plant. This plant is placed on the surface of the subject material: a transparent or translucent overcoat layer is formed so that no air remains between the covering layer and the surface of the subject material.

The present invention further provides a method for producing a label comprising a press-dried plant comprising the following steps. The collected plants are sandwiched with a desiccant between two flexible sheets, or between the flexible sheet and the cushion sheet.

The plant is dried under pressure in a dry atmosphere. The completely dried plant is stored in a sealed bag of gas barrier material containing desiccant and oxygen absorbent.

This plant is removed from the pouch just prior to making a label containing the press-dried plant. The plant is placed on the surface of the first adherent film attached to the surface of a temporary carrier such as a release sheet or a third transparent or translucent sheet.

The plant is covered with a transparent or translucent second self-adhesive film. Pressure is applied to prevent air from remaining between the first and second films, and the second film is bonded to the first film, and the first and second films are cut to make grooves near the plant. In addition, the present invention relates to articles produced by the method, such as postcards, bookmarks, mails, folders or labels comprising compression-dried plants.

The method for producing a press-dried plant article according to the present invention comprises assembling the article by i) drying the collected plants, ii) storing the dried plants, and iii) removing the plants from the storage and adhering the surfaces to sheets, cards, and the like. It consists of steps.

These steps will be described next.

[Drying step]

Plants such as flowers are placed on a flexible drying sheet (eg paper, fabric, etc.) and inserted with a desiccant, preferably a strong desiccant, and covered with a cushioning sheet of flexible drying sheet, cardboard or woven urethane mattress. Form a dry unit. Many dry units are stacked to form a thin laminate and then pressurized from the outside in a room or chamber.

When the thin laminated piece is pressed from the outside, the drying sheet into which the desiccant is inserted is deformed and adheres to the surface of the plant so that the desiccant is close to the plant, thereby improving the drying efficiency and shortening the drying time.

The drying process may be performed by using a desiccant alone or by a heating source using an electric heater or the like together with the desiccant. In the latter case, one or more heating sources may be disposed between the top, bottom, and / or pieces of the laminate. When the heating sources are operated simultaneously, drying takes place quickly and the drying time is reduced to 1 / 3-2 / 3 of the time spent using only desiccant.

Powerful desiccants inserted into the drying sheet include anhydrous magnesium sulfate, anhydrous calcium chloride and lithium chloride. The drying step of the conventional method using silica gel takes 7-10 days, but the drying step of the present invention is 3-4 days when only the drying agent is used without heating, and when the drying agent is used while heating by a heating source. It can be shortened to 1-2 days.

The crimping means used in the drying step is usually a cylinder, a compactor or a simple pressure by weight. No great pressure is needed. The drying step can be carried out in a dry atmosphere such as a room or a chamber having a relative humidity of about 40% or less.

[Save phase]

The dried plant obtained by the drying step is stored in a gas barrier bag impregnated with a desiccant and an oxygen absorbent. As the desiccant, anhydrous magnesium sulfate, lithium chloride, anhydrous calcium chloride and the like can be used. As an oxygen absorber, iron powder is generally used.

The desiccant maintains or improves the dry state of the dried plant and the oxygen absorbent prevents the discoloration of the dried plant due to the air in the bag. According to the storage step of the present invention, the clarity of the natural color of the plant can be maintained for 3-4 years when the dry plant is stored in the dark. Thus, the next assembly step can be performed any number of times depending on the desired time and number of products.

[Assembling step]

Compression-dried plants are removed from the gas barrier bag only when the article is made. Carefully pick up the dry plant with tweezers and place it on the surface of the material, such as sheets, cards, or general household items. The bottom is covered with a transparent or translucent film coated with an adhesive, such as a pressure sensitive adhesive, and the film is brought into close contact with the surface of the plant and the subject under pressure or heating pressure such that no air remains between the surface of the subject and the plant or film. As a method of bringing the film into close contact, a method of adhering a transparent or translucent film coated with an adhesive such as a pressure sensitive adhesive thereon under pressure, under intense heating, welds the surface of a resin film, a card, a sheet or the like, and at the same time its gas permeability For example, to remove the gas and convey the gas barrier properties.

Since the air is removed and the film adheres tightly, there is no refraction or reflection by the air layer, so that the shape, pattern and color of the plant appear clearly in three dimensions without interference by the film.

Moreover, due to the absence of air, dry plants are not oxidized, do not absorb moisture, and do not discolor for long periods of time. In order to improve the adhesion of the transparent or translucent film and to completely remove the air layer, the adhesion step of the transparent or translucent film must be performed in the vacuum chamber.

As another method of adhering a transparent or translucent film, there is also a method of covering the surface of a target material with a transparent or translucent plastic resin or dropping the resin drop by drop to cover and fix the plant with a resin. This method also reduces plant bleaching.

If the pressed-dried plant article is enclosed in a moisture-proof, transparent packaging material with desiccant in the final assembly stage prior to sale, discoloration during sales distribution can be much reduced if the seal is not broken before use of the article.

Moreover, if the desiccant and oxygen absorbent are impregnated with the vent-drying plant together with the vent, the discoloration can be further reduced.

If a combination of a film and paper bonded to each other with a pressure sensitive adhesive, or two films, is used as the target material, a label containing a press-drying plant sandwiched between the two films may be obtained from the above paper or the film below. It can be used by releasing. In this case, a small label can be used by releasing only a portion of this article if the adjacent grooves around the plant were cut through the two upper films.

EXAMPLE

Next, the present invention will be described in more detail. It is by no means limited to the following examples.

Under pressure, and further round the center around the plant, making the grooves 28 tapered with a pressure blade from the transparent self-adhesive film 18 to the self-adhesive 27, ie just above the discharge paper 26.

In use, the self-adhesive paper 27 and the transparent-adhering film 18 are removed from the discharge paper 26 along the grooves 28 and placed on the underside of a desired portion such as a notebook 56, an adhesive portion of an envelope, or a general household article. Bond with a coated pressure sensitive adhesive.

Each press-dried plant article described above is stored in a gas barrier bag 29 containing a desiccant.

Example 2

The embodiment illustrated in FIGS. 13-15 comprises a press-dried plant on a carba sheet prepared by a method of thermally bonding an opaque film 30 to bond it to a cover 15 and a plant 4. It is a local mail folder 31.

The mail folder 31 is placed in an envelope and stored in the transparent gas barrier bag 32. The desiccant 33 is inserted between the cards 15 on the rear side of the postal folder 31 to make several small vents 34 on the surface thereof. In the case of the postal folder shown in FIG. 6 and FIG. 7, the desiccant was stored in a gas barrier bag including another small bag containing the desiccant without placing the desiccant between the folders.

The drying and storage steps of this example were as in Example 1.

In the manufacture of the product, the gas barrier bag 12 is teared off as shown in FIG. 12 and the dried plant is taken out. It is arranged in a desired shape on the front cover of the mail folder 31 having the vent 34 and containing the desiccant 33. Acetate (20-40 μm) respiratory clear membrane film 30 was applied thereon, and in addition, the thermal pressure plate 35 (25-125 ° C.) of the presser 35a was coated with a transparent acetate film 30, a card (15). ) And pressed over the dry plant 4 to remove the air transversely and through the film, effectively bonding without leaving air therebetween. 14 and 15 illustrate the article produced. In addition, the transparent film 30 is fused to the surface of the card 15 and the plant 4 to remove gas permeability and to impart gas barrier properties. Transparent acetate can also be used as the cover film. In this case, the heating temperature is about 25 ° C. Moreover, the film may be transparent or translucent and may or may not coat a pressure sensitive adhesive on the underside.

Example 3

As shown in FIG. 16, this embodiment is an embodiment of the invention as specified in claims 18-20. Ten sheets of low paper are bundled and immersed in saturated aqueous calcium chloride solution and dried at 100 ° C. to form a drying sheet 3 having a thickness of about 5 mm. The plants are arranged on the drying sheet 3 and covered with a urethane mattress 5 having a thickness of 2 mm. Overlaid about 20 units and pressurized with a load of about 40 kg without heating in the dehumidification chamber.

The plants were dried for about 3-4 days, which was about half of the time spent with conventional methods using silica gel. This dried plant 4 had a bright color close to that of the natural plant in comparison with the silica method. The dry plant 4 was taken out, arranged on the earth 11, covered with a transparent film and placed into a transparent bag 12 having low permeability to moisture and oxygen. A breathable bag 13 containing anhydrous magnesium sulfate, anhydrous calcium chloride or a mixture thereof was also placed under the sheet 11 in the transparent bag 12. By putting the dry plants into the atmosphere having the low humidity and low oxygen concentration described above, decolorization of the plants due to air oxidation through water or auto-reduction has been significantly prevented. This storage preserved the natural color and shape for 2-3 years. In the manufacture of the product, the pouch 12 is opened and the dried plant 4 is taken out of it and placed on the surface 41 of the upholstery, card or the like. The unsaturated diethylacetal resin 42 was then gently dropped from the feeder 42a onto the dry plant to fix the dry plant on a protective coated surface about 0.5-1 mm thick. Since the resin coating treatment described above actually blocks air completely from the dried plant, decolorization due to moisture absorption and oxidation is reduced.

Example 4

The press-dried plant article shown in FIGS. 17 and 18 is an embodiment of the invention as defined in claim 27 and corresponds to the improved article of Example 1 as shown in FIGS. 11 and 12. In this embodiment, the first film 50 having a white lively background and transparent portion 54 around the dry plant is adhered to the second film 51 with a weak pressure-sensitive adhesive 52 and the dried plant 4 ) Was placed on it, and then further covered with a third transparent film 53 having a pressure sensitive adhesive on the underside thereof. As in Example 1, air was removed while contacting the third film with a pressure-sensitive adhesive while compressing it with a rubber roll. Well, the second and third transparent films 51 and 53 were cut along the outside of the transparent portion 54 with a pressure blade to make the grooves 55.

The labels of this embodiment were used as in the labels shown in FIGS. 11 and 12 by peeling off the second and third transparent films 51 and 53 and sandwiching dry plants from the first transparent film 50.

In the present embodiment, both sides of the outside of the dried plant are transparent, so the plants in the label, can be seen from both sides. In addition, the labels can be glued to ordinary household items, fabrics, documents and the like and merged with them so as not to be noticed, thereby improving their aesthetics.

As described above, the press-dried plants can be prepared according to the present invention in a state of similar color and shape to that of nature and stored for a long period of time without discoloration. In addition, because dry plants can be stored for a long time, the articles can be made at any time, thus making press-dried plant articles irrespective of time of flowering or collection. Moreover, the commercial and aesthetic value has been significantly improved since the ratio of plants to products obtained therefrom can be increased.

Although the present invention has been described with reference to specific embodiments, it is contemplated that various changes and modifications will fall within the spirit, scope and concept of the present invention for those skilled in the art.
