By this method, the adhesiveness of the film is improved and the deterioration of the pressed flowers due to air is eliminated and irregular reflection is prevented to make the contour of the pressed flowers clear and the pressed flowers can be brought to an almost natural state and the hue discoloration of pressed flows can be prevented over a long period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for producing pressed flower cards for viewing that do not change color over a long period of time.

(Prior Art) Conventionally, in order to appreciate or preserve a pressed flower card that has been attached to a card with an adhesive film or the like, there have been cases where the pressed flower card is stored in a transparent bag or the like to protect the pressed flower card. In addition, this type of pressed flower card is made by interposing dried pressed flowers between a transparent synthetic resin film coated with heat-sensitive adhesive on the back and a mount, and applying heat and pressure to create a film, dried pressed flowers, etc.
A method for producing pressed flower cards that integrates the mount was developed in 1988.
It is disclosed in Japanese Patent No. 2999.

(Problem to be Solved by the Invention) However, in this conventional pressed flower card in which dried pressed flowers are simply pasted with an adhesive film and then stored in a transparent bag, the adhesive film cannot be applied to the periphery of the pressed flowers or in areas with severe unevenness. Because the paper is not in close contact with the card, the tubes reflect outside light diffusely, making the outline blurry.Also, there are no long-term moisture-proof measures inside the bag, which makes pressed flowers difficult to use. However, there was a problem in that the bright colors discolored within a short period of time. Therefore, there is a problem that if the cards are stored for a long period of time or are used for viewing purposes or as a commemorative item, the sense of luxury and freshness will be diminished, making it impossible to increase the product value. Matami Kaisho 61-2999
In the method for producing a pressed flower card disclosed in the publication, since the pressurization is performed under atmospheric pressure, there are cases where the air between the film and the mount is not sufficiently removed. In addition, in order to melt the heat-sensitive adhesive, it is necessary to heat the film at a temperature of about 90°C to 110'C for a long time, which causes the film to stretch significantly, causing warpage in the paper mount that returns to room temperature after bonding with the heat-sensitive adhesive. let Moreover, the heating time is long, the pressed flowers are likely to discolor and change in quality, and the production efficiency is low. Furthermore, when using the cited heat-sensitive adhesive, there was a problem that it did not have adhesive strength at room temperature, and the pressed flowers had to be temporarily fixed to the mount/film using another adhesive, resulting in poor workability.

(Means for Solving the Problems) The present invention has been made to solve the problems of the conventional art, and its purpose is to provide pressed flowers for pressed flower cards to be kept as ornaments or as commemorative objects. The beautiful colors of the paper are clearly expressed, and the color does not change over a long period of time. Therefore, the product value can be increased at once. Also, it is easy to manufacture, has high production efficiency, and does not cause warping of the mount. The purpose is to provide a method for producing pressed flower cards. The gist of the invention is a pressed flower card manufacturing method A which consists of the following steps A-B-C: dry pressed flowers are coated on the surface of the card in the desired position and arrangement with an adhesive film having an adhesive layer on the lower surface, and then dried. Temporary fixing process B in which pressed flowers are temporarily attached to the card surface: Pressure process C in which the pressed flower card, which has been covered with a film and temporarily fixed pressed flowers in the temporary fixing process, is heated and pressurized in a vacuum container to adhere the film and remove air. : The pressed flower card, which has been sealed with film and air removed through the pressurization process, is sealed in a moisture-proof transparent envelope with a desiccant and stored for a long period of time.

(Function) In the present invention, firstly, the entire surface of dried pressed flowers is covered with an adhesive film to coat the surface of the card, and then the adhesive film is coated with heat and pressure in a vacuum container, so that the adhesive film becomes flexible and Because of the pressure applied, the air is completely expelled and the adhesive film adheres to the entire surface of the card without any gaps, even in areas where it does not adhere well and forms an air layer, such as on the riverside of pressed flowers or on extremely uneven areas. . Therefore, since there is no diffuse reflection of outside light on the pressed flower parts, even the gaps between the pressed flowers are beautifully expressed. Moreover, since this card is enclosed in a moisture-proof transparent envelope along with a desiccant, the beautiful colors of the pressed flowers are clearly expressed, and the color does not change over a long period of time. In addition, in the present invention, since the adhesive force of the adhesive layer of the adhesive film is used as the adhesive force of the film, pressed flower, and mount, heating is only required to soften the film to make it easier to adhere, and the heating time is extremely short, about 0.3 seconds or less. This method does not discolor or deteriorate the pressed flowers over time, has high production efficiency, does not cause warping of the mount, and can be easily temporarily fixed using the adhesive strength of the adhesive film, making it an easy manufacturing method. ing.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

The pressed flower card (1) of this example consists of a dried pressed flower (2), an air-permeable card body (3), an adhesive film (4) with an adhesive layer on the bottom surface, and a transparent envelope containing a desiccant (5). (
6) for long-term preservation. When necessary, the transparent envelope (6) is torn and the pressed flower card (1) is taken out and used.

The dried pressed flowers (2) are dried in a container in which various flowers are pressurized in advance and are finished in a sheet shape. This dried pressed flower (2) is placed at an appropriate position on a thick card body (3), covered from the top with an adhesive film (4) with a matte surface, and then attached to the card body (3). At this point, the adhesive film (4) is only lightly pressed against the card body (3) to temporarily fix the dried pressed flower (2) so that it does not move (temporary fixing step). The pressed flower card (1) thus completed is heated and pressurized from above the adhesive film (4) inside a vacuum container. At this time, the air layer remaining in the periphery of the dried pressed flower (2) or in the highly uneven areas is also removed from the periphery of the adhesive film (4) by the differential pressure. Further, a small amount of residual air is also permeated through the card body (3) to the back surface thereof and discharged due to the pressurizing force and the air pressure difference. Therefore, the adhesive film (

pressurization process).

Further, the desiccant (5) is a strong material containing anhydrous magnesium sulfate as a main ingredient, and is formed in the form of a sheet.

Furthermore, the material of the transparent envelope (6) is preferably one that is resistant to scratches and scratches and is as thick as possible; for example, a thick polyester film is used. Then, the pressed flower card (1) and a desiccant (5) are arranged on the back side thereof are inserted into a transparent envelope (6), and the envelope opening is tightly sealed.

According to this embodiment, the adhesive film (4) is a dried pressed flower (2).
are bonded without creating an air gap along the edges.

For this reason, the shape and color of dried pressed flowers (2) are beautifully expressed down to their delicate details. Furthermore, since this pressed flower card is enclosed in a moisture-proof transparent envelope together with a desiccant, the beautiful colors of the pressed flowers will not change color over a long period of time, thereby increasing the commercial value.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to these embodiments, and even if there are design changes within the scope of the invention, the technical scope of the present invention will still remain within the scope of the present invention. shall be.

(Effects of the Invention) As explained above, according to the present invention, by using an adhesive film, pressed flowers can be temporarily fixed quickly, and displacement and movement of pressed flowers due to pressure in the pressing process can be reduced, and in addition, vacuum Since the process is heated and pressurized in a container, the film has good adhesion, and there is no deterioration due to air, and there is no diffused reflection, so the outline of the pressed flowers is clear and the pressed flowers can be pressed in a state close to natural. Furthermore, air can be removed easily and quickly, high pressing force and high heating temperature are not required, and pressed flowers are less likely to be deformed or altered in quality. Moreover, since the pressed flowers are stored together with a desiccant in a moisture-proof transparent envelope, the pressed flowers can maintain their color for a long period of time without changing color.
