2. Description of the Related Art Dried pressed flowers can be displayed as they are,
Affixed on paper, film, etc., sandwiched between thin paper and cardboard, or between films, further attached to cloth,
Alternatively, it is used by being attached to a harder plate. When the dried pressed flower is used by attaching it to various substrates, if the substrate is paper, cloth, soft film, etc., the substrate is soft, so no matter how well attached, the substrate is rubbed, If it is bent, dried pressed flowers will also
It will be rubbed and bent in the same way. Therefore,
When the base material is soft, the use of the base material prevents the dry pressed flower from being damaged by devising the pressed flower so as not to be rubbed as much as possible.

On the other hand, when the base material is a hard plate-like material, it is simply pasted or at least one glass plate is used while sandwiching dried pressed flowers. In this case, the dried pressed flower is simply sandwiched or simply glued, so that the position of the dried pressed flower is shifted,
It was difficult to put a large number of flowers, even if they could put a small amount of flowers, because they would lose their shape.

Further, it is known from JP-A-63-239091 or the like to fix dried pressed flowers to a substrate using a hot melt film.

[0005] However, in any of these methods, the flowers handled are limited to those that are relatively flat and thin, or those that do not feel uncomfortable when crushed flat. Especially when using a hot melt film, there is a limit to the wrapping of the flower-melted film, and the enclosed material is thick, irregular, severe, relatively thick, and hard. In the case, the hot melt film and the flower do not completely adhere to each other, and the hot melt film wraps the whole while keeping the space, so if it is a pressed flower, it will change color or thigh color after enclosing it However, it was difficult to maintain the elegance of the flowers for a long time.

[0006]

Izu above 7及至above 9, wherein a made of the second step of
A method for manufacturing thick sealed decorative items. The purpose is achieved by.

The details will be described below with reference to the drawings. 1 to 4 are front sectional views showing different embodiments of the thick sealed decorative article according to the present invention. FIG. 5 is an explanatory view of the method for producing a thick sealed decorative article of the present invention. In FIG. 1, 1 is an airtight transparent material, 2 is an airtight material, 3 is an enclosed thick material, and 4 is a molten and solidified plastic powder. Here, the thick material 3 means a material having a thickness, a material having irregularities on the surface, a material having a depth as a whole, a material having a hard surface, and the like. For example, in the case of a dried pressed flower, it means a thing having a depth such as a lily of the valley, a thing having an uneven surface such as a flower of Ji, or a hard thing such as a twig of a tree. Furthermore, like the flower core of a dandelion, there are irregularities on the surface,
Naturally, those having a relatively large thickness are also included. In addition, the irregularities range from large irregularities to small irregularities such as irregularities due to small hair growth on flower stems.

The airtight transparent material 1 needs to be transparent as a whole. The airtight transparent material 1 does not enter the thick side where air or moisture is sealed from above,
It is provided for seeing through the enclosed thick material. The hermetic transparent material 1 can be composed entirely of a hot melt film. In addition, as shown in FIGS. 2 to 4, the hot melt film 5 and the transparent additive 6 can be used in an overlapping manner. As the transparent additive 6, for example, a transparent film, such as a polyester film, which is hardly damaged, a transparent plastic plate, a transparent glass plate, or the like can be considered. And used repeatedly these, may be airtight transparent material as a whole. Further, when the airtight transparent material is a synthetic resin material, the outside thereof may be coated with a transparent resin. Transparent resin coating has the effect of giving the protection of the synthetic resin-made air-tightness of transparency material, the gloss on the ornaments.

The airtight material 2 can have various various configurations. However, in any case, airtightness is required, that is, airtightness for preventing the intrusion of air or moisture from below toward the enclosed thick material side.
The simplest construction of the hermetic material is to construct the hermetic material only with a hot melt film. Next, the hot melt film is used by being superimposed on the airtight additive 8 as shown in FIG. 2 or FIG. In this case, the material and condition of the airtight additive to be superimposed on the hot melt film can be selected widely. For example, even if it is soft,
Hard, thick, thin, transparent,
It can be opaque.

Still another configuration is that, as shown in FIG. 3, an airtight material is a plate-like material selected from metal, ceramics, glass, wood, plastic, rubber, resin-coated paper, etc., for example, a ceramic plate 9. , To configure. In this case, a plate made of these materials has the airtightness required in the present invention as such. Yet another configuration of the hermetic material allows the hermetic material to be selected from flexible sheets, such as cloth, leather, paper, and plastic sheets.
Of these sheets, other than the plastic sheet, the other sheets generally have poor or little airtightness. Therefore, it is conceivable to apply resin processing to these flexible sheet materials to give them airtightness before use. In this case, use may be made of only the processed flexible sheet. A hot melt film or a plastic film may be attached to a soft airtight flexible sheet. FIG. 4 shows a case where the leather 10 is used by being superposed on the hot melt film 7. In addition, the hermetic material may be formed by laminating a plurality of types of materials. In this case, if a plastic film is included as one of the laminating materials, it can be used satisfactorily even if other materials are inferior in airtightness.

The solidified plastic powder 4 is a material in which a low-melting-point plastic powder or granule is once melted in a state of being placed around a thick material, and then solidified as it is. When the plastic powder is placed around a thick material, it is a powder or a granule. Therefore, on the outside of the thick material, it is positioned so as to fill the outer voids, and on the surface of the thick material, irregularities are formed. It can be located in a recessed part of the part. When melting is performed in this state, of course, the fluidity is exhibited, as well as the portion that was previously positioned, and easily penetrates into the gap existing between the hermetic transparent material and the hermetic material, and the gap is made of plastic. The melt of the granular material is buried. Thereafter, when the melt solidifies, the space between the hermetic transparent material and the hermetic material is completely solidified, including the periphery of the thick material, that is, the concave portion of the thick material and the portion immediately near the thick material. It will be buried in. Therefore, there is no bubble-like encapsulation of air or moisture.
Also, the outside of the airtight transparent material becomes flat, or
It becomes the expected smooth bump, and regardless of the inclusion of thick material, it forms extreme irregularities, and irregularities similar to flower irregularities that tend to occur when sealing dry pressed flowers occur outside the airtight transparent material Things can be avoided.

The placement of the plastic granules around the thick material does not require nervous and fine placement. That is, if it is roughly arranged, after it is in a molten state, the molten material flows and enters to find a void. The application of heat and pressure assists in the intrusion into the voids, and furthermore, completely melts up and down the thick material. Care must be taken in selecting the material of the plastic powder. That is, when a hot-melt film is used as the airtight transparent material, it is easy to use the same material as the material of the hot-melt film, and there is no problem. This is because if the material is inadvertently selected, the whole may lose transparency due to a combination with the properties of the airtight transparent material. In addition, it is preferable to mix and use an antioxidant and / or an ultraviolet absorber in the airtight transparent material and / or the plastic powder.

The thick sealed decorative article of the present invention thus obtained is
This makes it possible to enclose a thick material that has conventionally been difficult to manufacture. Conventionally, it has been considered to enclose dried pressed flowers and the like by disposing a hot-melt film on one side or both sides, but in any case, the encapsulated thing must be thin. That is, for example, when the dried pressed flower is thick,
Even if the hot melt film on one or both sides melts,
It was difficult to completely seal the dried pressed flowers with a molten film. Especially when there is something hard like a branch of a tree, the molten film cannot access a portion near the branch, and a gap has been created there. Similarly, in the case where there is unevenness, the molten film could not cope finely, causing voids. In order to cope with these problems, the thickness of the hot melt film to be used has been increased, but it was difficult to achieve the desired effect.

The inventor of the present invention pays attention to the fact that the use of plastic granules has much higher fluidity when molten than in the case where the original form is a film. It has reached. Regardless of whether the enclosing material is thick, uneven, deep, or hard, the enclosing material has no bubbles or moisture bubbles inside. The fill is completely sealed with finely-melted solidified material. This is very difficult with conventional techniques and cannot be perfect. In addition, the upper side of the hermetic transparent material on the surface of the decorative article of the present invention is a smooth or smooth bump. This means
It dramatically improves the value as a decorative product, and can greatly enhance its elegance compared to a product having a surface with unevenness by a conventional method.

Referring to FIG. 5, the manufacturing method of the present invention will be described. In the manufacturing method of the present invention, there are a case where all the steps are performed in one continuous step, and a case where it is more preferable to perform the steps separately in the first step and the second step. Although not shown, the first step in the case of dividing the steps is to heat-adhere a hot melt film on a substrate to previously form an airtight material. The substrate 13 is formed by selecting one or a plurality of appropriate materials such as metal, pottery, glass, wood, plastic, rubber, and paper. A hot melt film 14 is overlaid on the substrate 13, and the hot melt film 14 and the substrate 13 are integrated by applying heat and pressure, and the hot melt film is adhered to the substrate. Thus, an airtight material is formed. The first step is performed separately from the encapsulation in advance in order to shorten the heating time applied to the encapsulation. This is because generally heating the substrate takes time. Performing the first step under a reduced-pressure atmosphere is effective for strengthening the adhesion between the hot melt film and the substrate.

The entire process in which the steps are not divided and the second step in which the steps are divided are very similar and almost the same. The main thing done here is encapsulation. In the case where the process is not divided, the airtight material is constituted simultaneously with the encapsulation, if necessary. In the second step in which the steps are not divided and in the case where the steps are divided, it is essential that the atmosphere be kept in a reduced pressure state before pressurizing and heating. It is preferable that the reduced pressure is set to a high vacuum state as much as possible.
This creates a state close to a vacuum between the hot melt film, sheet, thick material, etc., and fine impurities, moisture,
The purpose is to completely remove the air and prevent them from being enclosed. Similarly, moisture, air, and contaminants are removed from the surface of a thick material such as a dried pressed flower.

The second step in the case where the steps are not divided and in the case where the steps are divided is started by placing an object constituting an airtight material, for example, a substrate and / or a hot melt film on the base plate 11. When the process is divided, the process is started by placing the airtight material already obtained in the first process. The work after forming the airtight material on the base plate or after mounting the airtight material obtained in the first step is the same regardless of whether the steps are divided or not. Then, a thick material 3 to be enclosed, for example, a dried pressed flower, is placed thereon. A plastic powder 19 is added around the thick material 3. The method of addition is not so strict. For example, the powder may be sprinkled over a thick material. The amount of addition is determined by the shape and size of the thick material. However, if the amount is small, there is a risk of causing a problem.

Next, the thick material 3 and the plastic powder 19
The hot melt film 15 is placed on the top. FIG. 5 shows a case in which a hot melt film 15 and a transparent film 16 with release paper are integrated. The order is hot melt film, film, release paper, release paper on top. The rubber sheet 17 and the foam sheet 18 are stacked on the release paper. The hot plate 12 is located on the foam sheet 18. The preparation is completed by being stacked in this manner.

In this state, the vacuum pump is operated to start reducing the entire atmosphere under reduced pressure, and the degree of reduced pressure is increased.
The decompression is sufficiently applied to remove the dirt and impurities from the surface and between the films, sheets, and thick materials.
Is pressed downward, and heating is performed while pressing the foam sheet 18 and below in the direction of the base plate 11. The operation is completed if the heating is performed for a predetermined time. Therefore, the work is completed by pulling the hot plate 12 upward, removing the foam sheet 18 and the rubber sheet 17, and taking out the completed decorative article from the hermetic transparent material to the hermetic material in a sealed state.

The reason why the foamed sheet 18 is used is that the unevenness due to the presence of the thick material 3 is gently received at the time of pressurizing and heating by the hot plate 12, and local breakage of the hot melt film 15 and the transparent film 16 with release paper is prevented. is there. The reason why the rubber sheet 17 is used is to secure a degree of vacuum between the substrate 13 and the transparent film 16 with release paper, thereby improving the operation efficiency of the vacuum pump. That is, the suction port of the vacuum pump is not shown in FIG. The use of the release film 16 with a release paper prevents the product from being taken out together when the rubber sheet 17 is removed, and the transparent film 16 with the release paper and the hot-melt film 15 make up the airtight transparent material at once. In addition, it is to complete it at the same time as the whole creation.

In the method of the present invention, the time required for heating is at most several minutes. That is, the plastic powder 19
This is because only the hot melt films 14 and 15 need to be melted. In the second step in which the steps are divided, the substrate 13 and the hot melt film 14 have the lingering heat of the first step. Accordingly, when the thick material 3 is covered, the plastic powder 19 is covered, the hot melt film 15 is covered, or the rubber sheet 17 or the like is covered and then heated under pressure, the temperature rises very quickly. The hot melt films 14, 15 or the plastic particles 19 can be melted in a very short time. Therefore, when the thick material 3 is, for example, a dried pressed flower,
The exposure time to high temperature can be minimized. Therefore, compared to the case where the processes are not divided, it takes less time to compare only the enclosing process.

[0023] In the present invention, the second step in the case of division, or after the step when no division, there is a row Ukoto a resin coating on the outermost layer. The resin coating protects the film and the hot melt film that make up the airtight transparent material from mechanical damage by carefully covering the outside, and gives the outermost layer a gloss and mat to improve the appearance. It is carried out as necessary for the purpose of beautification, to make the inclusions, for example, dried pressed flowers more attractive, and sometimes to prevent the intrusion of light, especially ultraviolet rays, into the inside and to delay the discoloration of the dried pressed flowers.
For this reason, the resin in the form of a film is placed on top, and with a part applied to the side of the substrate, while applying light pressure to the whole, the resin is heated and melted to seal the whole,
Alternatively, it is performed by applying or spraying a molten resin on the outermost layer to unite the whole. As the coating resin, an appropriate material can be used as long as the above-mentioned purpose is achieved. It is preferable that an antioxidant or an ultraviolet absorber is mixed in the coating resin.

In the thick sealed decorative article obtained by using the manufacturing method of the present invention thus configured, the encapsulation is formed by melting and fixing the plastic particles between the two hot melt films. Even if it is hard, it is completely sealed by close contact, air and moisture are completely eliminated, and the hot melt film is completely adhered to the substrate and the film, and the whole is sealed integrally Thus, the enclosure is completely protected from external scratches, air and moisture ingress and other adverse effects. Thus, the inclusions, such as dried pressed flowers, can retain their elegance for a long time. If an antioxidant and / or an ultraviolet absorber is mixed into a film, a plastic powder, or a coating resin that constitutes the airtight transparent material, the deterioration of dry pressed flowers due to light, for example, is longer. Can resist.

When the process is performed for two minutes in the production, the influence of the heat on the inclusions, for example, the dried pressed flowers in this part of the process is minimized, and the beauty life of the flower can be prolonged. Things. Also, performing the first step of heating and attaching a hot melt film on a substrate to form an airtight material separately from the other steps shortens the heating time of the second step mainly involving enclosing a thick material. Therefore, the overall processing time can be shortened, the heating can be effectively performed, and the influence of the heating on the enclosure can be minimized. In addition, when the process is not divided, the necessary materials are simply stacked one after the other, and only by pressing and heating all at once, the airtight transparent material, the airtight material, and the encapsulation of thick materials are all processed in one process. Therefore, the process is simple regardless of the variety of products.

[0026]

As described above, according to the present invention, since a thick material is completely sealed around its periphery, for example, even when a dry pressed flower is used as a thick material, a complete sealing which could not be performed conventionally can be performed. As a result, it is possible to obtain a decorative article whose elegance can be maintained for a long period of time as in the case of a flat dry pressed flower. Therefore, it is possible to provide a manufacturing method with a high success rate, since it is possible to minimize the adverse effect of the method, to enable complete sealing, and to complete the process. As described above, the present invention has excellent practical effects and excellent effects.
