Description

The present invention relates to a technique for facilitating the handling of gold leaf such as transportation and pasting of gold leaf.

Decorative gold leaf used for decoration of lacquer ware and folding screens (hereinafter, simply referred to as "gold leaf") has a size of 10 cm to 20 cm square, but a thickness of 0.1 to 0.3 μm, which is very thin. As a single unit, it bends or wrinkles with a slight wind pressure, and requires skill in handling it. In order to facilitate the handling of the gold leaf, the gold leaf cut to a predetermined size is adsorbed on the resin sheet by using static electricity, and the gold leaf is handled together with the resin sheet.

That is, the gold leaf cut to a predetermined size is adsorbed on a resin sheet such as PE (polyethylene) or ОPP (Oriented Polyprolylen) by using static electricity, and the resin sheet is conveyed in a state where the gold leaf is adsorbed. The surface on the side where the gold leaf is adsorbed is attached to the decorative object, and then the resin sheet is peeled off to attach the gold leaf to the surface of the decorative object (Patent Document 1). ). Since the surface of the decorative object is coated with lacquer or other adhesive paint, if the gold leaf adsorbed on the resin sheet is attached to the surface of the decorative object and the resin sheet is peeled off, the gold leaf will be removed. It is affixed to the surface of the decorative object without causing wrinkles or creases.

It is widely practiced to attach finely cut or broken gold leaf to the surface of foods such as Japanese sweets for decoration. On the other hand, it has come to be carried out that a gold leaf having a certain size is attached and provided so as to cover the entire surface of the soft serve ice cream. That is, in the past, a small part of food was decorated with gold leaf, but recently, gold leaf is attached to a wide area of the food surface to provide the food.

Those who perform the work of attaching gold leaf to food are those who are unfamiliar with the handling of gold leaf, such as confectioners. Therefore, the work of attaching gold leaf to the surface of food is more difficult than the work of attaching gold leaf to the surface of lacquer ware, Buddhist altars, etc., and it cannot be attached well.

An object of the present application is to solve this problem, that is, to facilitate the work of attaching a gold leaf having a certain size to the surface of a decorative object having a free-shaped surface. In Patent Document 2, a technique for facilitating the handling of gold leaf such as transportation and pasting of gold leaf is proposed.

In Patent Document 2, a three-layer structure is provided in which an interposition sheet that prevents the gold leaf from being adsorbed to the resin sheet is provided between the resin sheet that adsorbs the gold leaf by electrostatic force and the gold leaf supported on the resin sheet. The gold leaf is adsorbed on the resin sheet with a part of the peripheral edge protruding from the peripheral edge of the intercalating sheet.

According to the means proposed in Patent Document 2, even a person who is unfamiliar with the handling of gold leaf can easily attach the gold leaf having a certain size to the surface of the decorative object having a free-shaped surface. It can be carried out.

However, when the decorative object is a food with a large amount of water, the moisture in the food infiltrates the interstitial sheet, and the moisture adsorbs the gold leaf to the interstitial sheet, making it difficult to peel off. When is a food containing a large amount of water, it has been found that the technique proposed in Patent Document 2 is incomplete.

The present invention has been made to solve the above-mentioned newly discovered problem, and even a person who is unfamiliar with the handling of gold leaf can apply a certain size to the surface of an ornament having a free-form surface. The work of attaching the provided gold leaf can be easily performed, and even if the object to be decorated is a food containing water, the work of attaching the gold leaf does not become difficult, and the desired decorative effect is achieved. The problem is to make it easy to attach gold leaf cut into a shape.

In the present invention, as the resin sheet 4 used when the gold leaf 3 is adsorbed on the charged resin sheet 4 and the gold leaf is transported and attached to the decorative object, at least the surface on the side where the gold leaf 3 is adsorbed is a water repellent agent. The above-mentioned problem is solved by using the resin sheet coated with.

That is, in the method for decorating a decorative object of the present invention, the gold leaf 3 is attached to a resin sheet and conveyed to the decorative object so that the gold leaf 3 is brought into contact with the surface of the decorative object, and then the resin sheet 4 is decorated. A method for decorating a decorative object to be separated from an object is characterized in that a resin sheet 4 having at least a water-repellent coat layer on the surface of the gold leaf 3 on the attachment side is used as the resin sheet.

The gold leaf supporting sheet 1 of the present invention is a sheet used in the above-mentioned decoration method, and is characterized in that at least the surface of the chargeable resin sheet 4 to which the gold leaf 3 is attached is a surface coated with water repellent. do. The resin sheet 4 has a size that covers the entire gold leaf 3, or has the same shape and dimensions as the gold leaf 3.

When the resin sheet 4 has the same shape and dimensions as the gold leaf 3, both ends 5a are placed on the opposite surface of the resin sheet 4 to the gold leaf attachment surface in order to improve workability when the gold leaf is attached to the decorative object. It is preferable to attach the handling tape 5 from which the 5b protrudes from the outer edge of the resin sheet 4.

The handling tape 5 is coated with an adhesive that can be easily peeled off on the portions other than the tips of the protrusions 5a and 5b, and the portion of the protrusions 5a and 5b near the outer edge of the gold leaf 3 is also attached to the interleaving paper 2. By doing so, it is possible to prevent the gold leaf 3 and the resin sheet 4 from shifting on the interleaving paper 2.

By handling the resin sheets 4 one by one, the gold leaf supporting sheet 1 having the above structure can handle the gold leaf 3 one by one without causing wrinkles or bending in the gold leaf 3. When the gold leaf 3 adsorbed on the resin sheet 4 is brought into contact with the surface of a decorative object such as soft serve ice cream or Japanese confectionery to separate the resin sheet 4, the gold leaf is separated from the resin sheet 4 and the soft serve ice cream or confectionery is soft and uneven. It can be moved to the surface of the object and attached to the surface of the object to be decorated without unnecessary wrinkles or creases.

Further, since the surface of the resin sheet 4 of the gold leaf supporting sheet 1 of the present invention is coated with water repellent on the side to which the gold leaf is attached, even if the decorative object is a soft serve ice cream or confectionery containing water, the resin is used due to the water content. The removal of the gold leaf from the sheet is not hindered, so even a confectioner who is not accustomed to the work of attaching the gold leaf can easily attach the gold leaf to the surface of a moist food or the like. become able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a first embodiment of the gold leaf supporting sheet of the present invention, and is an exploded perspective view showing an example of the simplest embodiment. In the figure, 1 is a gold leaf supporting sheet, 2 is a slip sheet, 3 is a gold leaf, and 4 is a resin sheet. In the figure, the gold leaf 3 and the resin sheet 4 are shown separately, but in reality, the two 3 and 4 are in close contact with each other.

The resin sheet 4 has a water-repellent coating on the surface attached to the gold leaf, that is, the lower surface in the figure. Specifically, it is a resin sheet with a water-repellent coat on the surface of polyethylene or polyethylene terephthalate, and optimally a water-repellent layer containing silica. For example, "Toyal Lotus" (registered trademark) manufactured by Toyo Aluminum K.K. A resin film coated with "Lotus Coat" (registered trademark) manufactured by Ito Optical Co., Ltd. can be used. The resin sheet 4 has a size that covers the entire gold leaf 3 or a size that is the same as that of the gold leaf 3.

Although the interleaving paper 2 is not a component of the gold leaf supporting sheet 1 of the present invention, it is attached in consideration of convenience such as transportation to the work site where the gold leaf 3 is attached to the decorative object, and has a certain degree of strength. It is preferably made of paper. The external dimensions of the interleaving paper 2 are large enough to cover the entire gold leaf 3 and the resin sheet 4.

The work of attaching the gold leaf 3 to the decorative object is performed by peeling the resin sheet 4 from the interleaving paper 2 and carrying it to a desired portion of the decorative object, and applying the gold leaf 3 to the surface of the decorative object. When the resin sheet 4 is peeled off from the interleaving paper 2, the gold leaf 3 is peeled off together with the resin sheet 4 due to the static electricity generated in the resin sheet 4, and is carried to a desired place of the decorative object while being attached to the resin sheet 4. Then, by bringing the gold leaf 3 into contact with the surface of the decorative object, the gold leaf 3 is separated from the resin sheet 4 and attached to the surface of the decorative object. Even if the decorative object is a food containing water, the surface of the resin sheet 4 on the gold leaf side has water repellency, so that the water does not hinder the peeling of the gold leaf 3 from the resin sheet 4.

As shown in FIG. 2, the gold leaf 3 and the resin sheet 4 can be cut out or punched into an appropriate shape for enhancing the decorativeness. When the cutout or punching shape is small, it is preferable to attach the handling tape 5 to the surface of the resin sheet 4 on the anti-gold leaf side. Both ends 5a and 5b of the tape 5 are projected from the outer edge of the resin sheet 4, and when the gold leaf is attached to the decorative object, the protruding portions 5a and 5b are pinched and carried to a desired location of the decorative object. The gold leaf 3 may be applied to the surface of the decorative object.

If a tape having a peelable adhesive layer is used as the tape 5 except for both tips, the tape 5 can be easily attached to the resin sheet 4, and both ends 5a and 5b protruding from the gold leaf 3 can be attached. The adhesive layer on the side close to the edge of the gold leaf 3 adheres to the interleaving paper 2, and it is possible to prevent the gold leaf supporting sheet 1 from shifting on the interleaving paper 2. Further, the interleaving paper 2 can be made into thick paper or the like, and one or a plurality of gold leaf supporting sheets 1 including the interleaving paper 2 can be enclosed in a bag and distributed.

When a large number of gold leaf-supported sheets 1 of the present invention are distributed in a batch, a package in which a large number of sheets are laminated can be obtained by sandwiching the interleaving paper 2. FIG. 3 is an exploded perspective view showing an example of such a package, in which the interleaving paper 2 is sandwiched between the gold leaf supporting sheets 1 for each sheet and stacked, and the interleaving paper 2 is attached to both end faces of the stacked sheets. Further, a protective plate 6 made of thick paper is attached to both sides of the laminated body, and the structure is bound in the vertical direction in the figure with a binding tape (not shown).

By distributing such a gold leaf distribution package as one unit, the gold leaf supporting sheet 1 according to the present invention can be distributed from a gold leaf manufacturer / distributor to a soft serve ice cream distributor or a Japanese confectionery manufacturer. Soft serve ice cream distributors and Japanese confectionery manufacturers untie the gold leaf distribution package and handle the gold leaf supporting sheets 1 one by one to decorate the surface of the necessary confectionery with gold leaf of the desired size. be able to.
