DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hermetically sealed dry pressed flower which is used mainly for decoration by bonding dried pressed flowers to a flexible and air-permeable base material such as fiber cloth, paper sheet and card. It concerns the manufacturing method.

[0002]

2. Description of the Related Art Dried pressed flowers can be displayed as they are,
It is used by attaching it on paper, film, etc., sandwiching it between thin paper and cardboard, or between films, and attaching it to cloth. 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 are similarly rubbed and bent. 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 in a position where it is not 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,
The dried pressed flowers will not be rubbed, even if they lose their shape.

[0004] Further, it is also known from JP-A-63-239091 or the like to fix a dried pressed flower to a substrate using a hot-melt film. However, as long as a hot-melt film is used, a heating step is not required. I can't avoid it. Therefore, it is not always a preferred treatment method for flowers.

[0005]

Is a flexible substrate, 2 is an air barrier film, 3 is a dried pressed flower, 4 is a hot melt film, 5 is a cover film,
6 is a coating resin.

[0008] The flexible substrate 1 is formed of a flexible material such as paper or a cloth made of various fibers. Substrates made of these materials are flexible as such,
Not only is it difficult to maintain the form, but it also allows air or moisture to pass through, or sometimes retains air or moisture by itself. In using the dried pressed flower, it is the most unfavorable environment that a mechanical force such as rubbing from the outside or contact with water is applied. The use of flexible substrates is not a favorable condition in this regard, but can be avoided with the need to use them with textiles and paper cards to make blouses and the like more beautiful or to make the cards more gorgeous. There is no matter.

The air barrier film 2 is easy to adhere to the flexible substrate 1 and can be widely selected as long as it is airtight. Therefore, any material may be used as long as it is stable, such as polypropylene, ethylene vinyl acetate, polyamide, polyester, and the like, and a low melting point film called a so-called hot melt film may be used. The thickness can also be selected relatively freely according to conditions such as the state of the soft base and the size of the dried pressed flower. When the hot melt film 4 is used on the dried pressed flower in the second step, the hot melt film 4 needs to be transparent. In addition, it is preferable that a property of absorbing ultraviolet light is provided. For this reason, it is preferable that the ultraviolet absorber is mixed in the film or applied to the film.

[0010] The material and thickness of the hot melt film 4
It can be selected from a wide range as long as it has the above properties. However, in the case of the hot melt film 4, depending on the type of the flower, it is necessary that the hot melt film 4 be thick enough to wrap the flower together with the air barrier film when melted.
Furthermore, melting relatively quickly is favorable for flowers. If a hot-melt film is used as the air-blocking film, when the surface of the hot-melt film, which is an air-blocking film, is in a molten state, it has the property that it melts quickly and the top and bottom are integrated. You should choose within the range of what you have.

The method for producing the dried pressed flower 3 is not particularly limited. Generally, fresh flowers are sandwiched between papers in a box containing a desiccant such as silica gel, and stacked with a breathable cushioning material. After bleeding the air in the box, after 2 to 7 days, The production is performed by taking out. In this case, the obtained dried pressed flower has a reduced water content, but if the drying is insufficient, it is easy to discolor even if sealed, and if the drying proceeds too much, it becomes difficult to handle, but the discoloration of the product In order to avoid this, it is preferable that the water content is small. Therefore, it is necessary to sufficiently dry the dried pressed flowers before putting them into the process, and it is preferable to put the dried pressed flowers into the process immediately after taking them out for about one day.

When a cover film is used, the cover film 5 is located outside the hot melt film 4 and is used for protecting the hot melt film and sometimes giving a pattern. The cover film 5 needs to be transparent. Further, the shape must be maintained at a temperature at which the hot melt film melts. As long as it has such properties, the range of selection is wide and various resins can be selected.

[0013] When using a coating resin, the coating resin 6,
It is provided so as to wrap everything from the top of the hot melt film 4, the top of the cover film 5, or further from the top of the dried pressed flowers 3, to the top surface of the flexible substrate 1 or, if necessary, to the side surfaces. Can be To make up the coating resin,
The resin already in the film state is placed on the outermost part, and while a part of the resin is in contact with the upper surface of the flexible base material or the side surface if necessary, heat and melt while applying light pressure to the whole Then, it is practical to seal the whole with resin.
Alternatively, a pressure may be applied once from the outermost surface to smooth the entire surface, and then the molten resin may be applied or sprayed to hermetically seal the entirety. For this reason, the coating resin is selected from those under conditions such as convenience of handling and a preferable state after application or spraying. For example, it is appropriately selected from systems such as polyamide, polypropylene, and polyester. It is preferable that the coating resin contains an ultraviolet absorber.

First, the first step is performed in manufacturing. The main purpose of the first step is to prevent air or the like from passing through the flexible base material. If the base material contains water, a barrier film should be formed so that it does not affect the dried pressed flowers. In the first step, an air barrier film is tightly adhered to a flexible substrate.
It is performed by a constant. Necessary it is to flexible substrate is to have a partially air barrier properties upon completion of this step, further, during which drying pressed flower does not relate to anything like the first step, it is isolated It is that you are. The air barrier film using a hot-melt film.
Place the hot-melt film 2 is air-blocking film on the soft軟基material 1, the whole atmosphere in a reduced pressure state.
Here, the depressurized state is preferably a depressurized state as high as possible. When the gauge of the vacuum pump indicates that the atmospheric pressure is 760,
Must be at least 200 or less. By heating the hot melt film while applying pressure in this state,
Lend dissolve the hot-melt film is bonded to the flexible substrate surface. Then, pressurization and heating are stopped, and the atmosphere is released. As a result, the surface of the hot melt film instantaneously drops in temperature and becomes solid. Since the heat capacity of the flexible substrate is not so large, the temperature starts to decrease.

Next, a second step is started. In the second step, the dried pressed flower is fixed to the air-blocking portion of the flexible substrate made in the first step. Using an adhesive, the dried pressed flower to contact wear on the air barrier film
You may do it. With dry pressed flowers, they are preferable to have use of the hot-melt film. Alternatively, instead of the hot melt, it may be used, usually of the cover film, also,
Even if you use a cover film with hot melt film
Good.

The case where the hot melt film is used as the air barrier film integrally with the flexible base material in the first step and the case where the hot melt film is used again in the second step will be described. On the air barrier film integrated with the flexible substrate in the first step, the dried pressed flower and the hot melt film which have been sufficiently dried are laminated. In this state, the atmosphere is reduced again. Therefore, when heating is performed while applying pressure from above the hot melt film 4, the hot melt film is melted up and down to be united, and the dried pressed flowers are completely sealed. If necessary, the cover film 5 can be stacked on the hot melt film 4 and the whole can be integrated by the hot melt film at once. Alternatively, the hot melt film 4 and the cover film 5 may be integrated in advance and used.

In the second step, as long as the hot melt film is used, the atmosphere is kept in a reduced pressure state before pressurizing and heating as in the first step. This reduced-pressure atmosphere is extremely effective, so that hot melt film and
A state close to a vacuum is created between the flexible base material and the hot melt film, and fine contaminants, moisture, and air are completely removed. Similarly, moisture, air, and contaminants are removed from the surface of the dried pressed flower. Therefore, it melts the hot melt film, flexible group
Materials or hot melt films contact each other,
Or, furthermore, when the hot melt film and the cover film are in contact with each other, and when the hot melt film is in contact with the dried pressed flower, the respective contact points are in direct direct contact without any interference. Will be.

As a result, the finished product is tightly integrated as a whole, and there is almost no probability that air or moisture exists therein. Therefore, there are no bubbles in the product, no melting of the petals, and no partial discoloration. It is important to have the process in two stages.
Since the heat capacity of a flexible substrate is generally not so large, it does not take much time to raise the temperature by heating. However, it is desirable to avoid the heating process for dried pressed flowers if possible.

In the present invention, by bonding the flexible base material and the air-blocking film in the first step by performing the steps in two steps, the bonding is performed completely in a state irrelevant to the dried pressed flowers.
Therefore, even if heating is performed in the first step or an adhesive or a solvent harmful to flowers is used, the dried pressed flowers are not affected at all. In the second step, even if a heating step is included, the adhesion between the flexible base material and the air barrier film has already been completed. Therefore, the heating required is only heating for melting the films for bonding the films to each other, so that the time and the amount of heat are not so small. Therefore, the time during which the dried pressed flowers are exposed to a high temperature can be minimized. This is most favorable for dried pressed flowers.

In the present invention, a third step of coating the outermost layer with a resin may be performed after the second step. The resin coating carefully covers the outside to protect the cover film and hot melt film from mechanical damage, and gives the outermost layer a gloss and matte, making the appearance more beautiful and enhancing dry pressed flowers more It is performed as necessary for the purpose of, for example, preventing light, particularly ultraviolet rays from entering the inside, and delaying the discoloration of the dried pressed flowers. For this reason, the resin in the form of a film is placed on top, and while a part is applied to the side surface of the flexible base material , while applying light pressure to the whole,
This is performed by heating and melting the resin to seal the whole integrally, or by applying or spraying the molten resin to the outermost layer to integrate 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 the coating resin contains an ultraviolet absorber.

The dried pressed flower sealed product obtained by using the manufacturing method of the present invention thus constituted has a structure in which the flexible pressed substrate allows air or moisture to pass through since the dried pressed flower is attached to the air barrier film. Even if included, it can be avoided from its effects. Furthermore, when the dried pressed flower is sealed using a hot melt film or a cover film, the whole is sealed as a whole, so that the dried pressed flower is completely protected from external scratching and other adverse effects. Moreover, since air and moisture do not enter from outside, the dried pressed flower can maintain its elegance for a long time. If an ultraviolet absorbing agent is mixed in the cover film or the coating resin, it is possible to resist the deterioration of the dried pressed flower due to light for a longer time.

[0022] per the manufacture, the Drying pressed flower is influenced by heat is minimized, it is capable to prolong flower beauty life. Flexible substrates are not resistant to the passage of air or water. It is also unstable in morphology.
However, the presence of the air-barrier film does not allow the dried pressed flowers to resist the passage of air or water, and thus contributes to maintaining the elegance of the dried pressed flowers. Therefore, the dried pressed flower integrally fixed is protected in terms of morphology, is stable, and is in a preferable state of being extremely safe chemically. The upper side of the dried pressed flowers can be protected with a hot melt film or, furthermore, with a cover film. In addition, the upper part can be sealed and fixed integrally with the base material with a coating resin, so that the base is extremely strong. It is integrated with the material and it is easy to secure that state. Therefore, the dried pressed flower is not damaged or displaced even after long-term use.

[0023]

According to the present invention, as described above,
Der which can be maintained elegance of dry pressed flowers obtaining a dried pressed flower sealed products available is, with respect to the dry pressed flower, the heat of the adverse effects minimized, allowing a perfect seal,
Since the process can be completed by a simple procedure, the present invention provides a method for producing a dried pressed flower sealed product having a high success rate. As described above, the present invention is highly practical and can provide excellent effects.
