Description

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

(Prior Art) Conventionally, there have been pressed flower cards with dried pressed flowers pasted on them using an adhesive film or the like, which have been stored in transparent bags or the like to protect the pressed flower cards for viewing or preservation. In addition, as this type of pressed flower card, dried pressed flowers are interposed between a transparent synthetic resin film coated with a heat-sensitive adhesive on the back and a mount.
A method for producing pressed flower cards that integrates film, dried pressed flowers, and a mount by applying heat and pressure was developed in 1988.
-Disclosed in Publication 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 stored in a transparent bag, the adhesive film does not adhere to the periphery of the pressed flowers or in areas with severe unevenness. Because the bag is not in close contact with the card, these areas reflect external light diffusely, causing the outline to fade.Also, there are no long-term moisture-proof measures inside the bag, which makes it very difficult to use. Pressed flowers also had a problem in that their bright colors would discolor within a short period of time. Therefore, there has been 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. Furthermore, in the method for producing pressed flower cards disclosed in Japanese Utility Model Application Publication No. 61-2999, since the pressurization is carried out under atmospheric pressure, there are cases where the air between the film and the mount is not sufficiently removed. Furthermore, 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 and cause the backing paper to warp when it returns to room temperature after bonding with the heat-sensitive adhesive. Also, the heating time is long and the pressed flowers change color.
It is easily deteriorated and 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 attached 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 are vividly expressed,
Moreover, to provide an excellent method for producing pressed flower cards that does not discolor over a long period of time, thereby increasing the product value at once, is easy to manufacture, has high production efficiency, and does not cause warping of the mount. There is a particular thing. The gist of the invention is method A for producing pressed flower cards, which consists of the following steps A, B, and C: Dried 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 agent and stored for a long period of time.

(Function) In the present invention, first, the entire surface of the dried pressed flower is covered with an adhesive film to coat the surface of the card, and then the adhesive film is heated and pressurized from above in a vacuum container, so that the adhesive film becomes flexible and Because of the pressure applied, the air is completely expelled, even in the areas around the pressed flowers and in areas with severe unevenness where the card does not adhere well and forms an air layer, and the adhesive film adheres to the entire surface of the card. do. 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. Furthermore, 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, the adhesion force of the film, pressed flower, and mount is based on the adhesive force of the adhesive layer of the adhesive film, so heating is only necessary to soften the film to make it easier to adhere, and it can be applied in an extremely short time of about 0.3 seconds or less. It does not discolor or change the quality of the pressed flowers, has high production efficiency, does not cause warping of the mount, and can easily be 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 embodiment 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 6 containing a desiccant 5.
stored for long periods of time. 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 upper surface with an adhesive film 4 having 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 produced is heated and pressurized from above the adhesive film 4 inside a vacuum container. At this time, the air layer remaining around the periphery of the dried pressed flower 2 and in the areas with severe unevenness is also removed by the adhesive film 4.
is removed from the periphery 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 by the pressurizing force and the air pressure difference. Therefore, the entire surface of the adhesive film 4 is brought into close contact with the card body 3 without leaving any air (pressure step).

Further, the desiccant 5 is a strong material containing anhydrous magnesium sulfate as a main ingredient and is formed into a sheet shape.

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

According to this embodiment, the adhesive film 4 is the 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. Moreover, 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, and the commercial value can be increased.

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.
Even if there are design changes that do not depart from the gist of the present invention, they shall remain within the technical scope of the present invention.

(Effects of the Invention) As explained above, according to the present invention, pressed flowers can be temporarily fixed quickly by using an adhesive film, and there is less displacement and movement of pressed flowers due to pressure in the pressurizing process. Since the film 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 flower is clear and the pressed flower can be made 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.
