Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a scented calendar.
More specifically, the strength and persistence of the fragrance can be easily adjusted, printing is easy, and not only can the printing ink print clear letters and designs without bleeding, but it can also be printed to match the calendar's design. To provide an incense calendar to which various fragrances can be imparted and the user can enjoy different fragrances for each month or day.

(B) Prior Art Traditionally existing scented calendars printed using scented paper sprinkled with or brushed with fragrances have a short duration of fragrance. In addition, the printing ink is smeared by the fragrance, making it impossible to print clearly, and in this respect, printing using expensive two-component curing ink or ultraviolet curing ink is not satisfactory. .

On the other hand, when using a scented plastic film made by directly impregnating plastic with fragrance,
Like the above-mentioned perfumed paper, it has very poor printability, and the bleeding of printing ink is even more pronounced.

A blended fragrance is a mixture of two or more of the above-mentioned natural fragrances and synthetic fragrances, for example, single-flower fragrances such as rose, diasmine, lilla, osmanthus, and carnation, or combinations of these. There are products that are prepared by adding various fragrances depending on the purpose.

(E) Effect The simplest structure of the present invention is a two-layer structure in which paper is laminated on one side of a fragrance-containing thermoplastic resin layer (hereinafter referred to as "fragrance-containing sheet"), or a two-layer structure in which paper is pasted on one side of a fragrance-containing thermoplastic resin layer (hereinafter referred to as "fragrance-containing sheet"), or both sides of a fragrance-containing sheet. This is a scented calendar consisting of a three-layered structure with paper pasted on it, and one scented laminate with a calendar printed on it.If necessary, the scent-impermeable sheet can be peeled off from the scented laminate. It is laminated on the paper surface or both outer surfaces, and at least the aroma-impermeable sheet on the printed surface is peeled off before use. By doing so, the fragrance will not be dissipated unnecessarily until the time of use, so not only will the fragrance continue even if the calendar is stored for a long time, but it will also fill the space with unnecessary fragrance. No more contamination.

Such aroma-impermeable sheets include metal foils such as aluminum foils, copolymers with high acrylonitrile content, saponified products of ethylene-vinyl acetate copolymers, polyvinylidene chloride resins, polyester resins such as polyethylene terephthalate, Examples include thermoplastic resins with gas barrier properties such as polyamide resins and polycarbonate resins, and cellophane.

Furthermore, in the present invention, by binding a plurality of sheets of scented laminates with different types of fragrances according to the calendar's design, etc., it is possible to enjoy a different fragrance for each leaf. At that time, in order to prevent different fragrances from mixing with each other, an aroma-impermeable sheet is placed between each fragrance laminate, or an aroma-impermeable sheet is laminated on the back side of each fragrance laminate. is essential.

(F) Embodiments The present invention will be explained in more detail below with reference to illustrated embodiments.

FIG. 1 is a perspective view showing an embodiment of the present invention. FIGS. 2a and 2b are partially enlarged sectional views of other embodiments, and FIGS. 3a and 3b are partially enlarged sectional views of a calendar in which a plurality of scented laminates are stitched together.

A fragranced calendar 1 shown in FIG. 1 is a single calendar made of a laminate of paper 2 and a fragrance-containing sheet 3. Such a calendar 1 can be used as a calendar with clear printing, and the user can enjoy the fragrance emitted from the layer of the fragrance-containing sheet 3.

The calendar of the present invention can also be formed by laminating papers 2 and 2' on both sides of a fragrance-containing sheet 3, as shown in FIG.
As shown in FIG. 2B, fragrance-impermeable sheets 4, 4' may be further laminated on both sides of the laminate shown in FIG. 2A. However, in this case, it is necessary to be able to peel off the aroma-impermeable sheet 4 or 4' attached to the printed side before use. By doing so, it is advantageous to prevent the fragrance from dissipating during storage before use.

Moreover, the calendar 1 shown in FIG. 3a is as shown in FIG. 2b.
A plurality of scented laminates are made by binding together a plurality of aroma-impermeable sheets 4 as shown in FIG. Furthermore, the calendar 1 shown in FIG. 3b is obtained by interposing an aroma-impermeable sheet 4 between each laminate as a slip sheet when binding a plurality of sheets of the laminate shown in FIG. 1. . Of course, a laminate as shown in FIG. 2a can also be used.

By configuring the calendar as described above, it is possible to enjoy various fragrances that match the design of each day or each month. Furthermore, in the embodiment shown in FIGS. 3a and 3b, a plurality of laminates containing the same fragrance are stitched together without using the fragrance-impermeable sheet 4, without changing the fragrance for each sheet. Of course, this is also possible.

The most preferable method for manufacturing the perfumed calendar of the present invention is to heat pellets obtained by impregnating soft resin A with a predetermined amount of the fragrance, or by heating pellets formed by mixing the fragrance into molten soft resin A. After kneading with plastic resin B and forming a sheet by an inflation method or the like, paper is laminated on one or both sides of the sheet by a common lamination method such as a dry lamination method or an extrusion lamination method. By doing so, excessive volatilization of the fragrance can be prevented, and a fragrance laminate containing a fragrance at a high concentration can be efficiently and inexpensively produced.

Further, the method for preparing the mixture of the soft resin A and the thermoplastic resin B, which are the most preferable fragrance-containing thermoplastic resins of the present invention, is not particularly limited, but for example, as described above, the soft resin A method in which A is impregnated with a fragrance and then melted and mixed with thermoplastic resin B in an ordinary kneader or extruder to form pellets, or a pre-melted soft resin A
A method of mixing a fragrance into pellets and dry-blending or melt-blending the obtained pellets with pellets of thermoplastic resin B, or a method of blending and film-forming in one step using an extruder. But that's fine.

In addition, the kneading machine used in the above method is
For example, Henschel mixer, Dalton mixer,
Examples include kneaders, Banbury mixers, hot rolls, and extruders.

The content of fragrance in this invention includes the type of fragrance,
It can be selected as appropriate depending on the type of calendar (daily or monthly), mode of use, type of soft resin A and thermoplastic resin B, etc.

For example, if flexible resin A is EVA,
The amount that can be impregnated with fragrance is roughly proportional to the vinyl acetate (VA) content of EVA. If the VA content is 30% by weight, almost 30% by weight of fragrance can also be impregnated. The strength of the fragrance increases as the amount of fragrance increases, but 0.01-1% by weight is present in the final product.
It is sufficient if the fragrance is contained in a certain amount, so for example, if fragrance-impregnated EVA is mixed with thermoplastic resin B from 10 to
When diluting to 100 times the volume, use soft resin A.
EVA may be impregnated with about 1 to 10% by weight of fragrance.

On the other hand, the persistence of the fragrance depends on the VA content and the mixing ratio of the fragrance-containing flexible resin A and the thermoplastic resin B such as polyethylene. For example, according to experiments by the present inventors, 10% by weight of the above fragrance
1 using low density polyethylene as thermoplastic resin B for impregnated EVA (VA: 15% by weight)
When diluted to 10 times the amount and further laminated with a non-fragranced thermoplastic resin sheet or paper, the fragrance lasts for about 0.5 to 1 year, and when diluted to 10 to 100 times the amount, the fragrance lasts for about 0.1 to 0.5 years. The fragrance lasted. The persistence of these fragrances also varies depending on the type of fragrance, the type and carboxyl group content of the flexible resin A, the type, thickness, and lamination mode of the thermoplastic resin B and paper, etc. It may be selected as appropriate depending on the purpose and use of the calendar.

In particular, in the present invention, soft resin A, e.g.
The fragrance effect can be adjusted appropriately depending on the amount of fragrance contained in EVA.
Since it is melted and mixed with
Moreover, the persistence of the fragrance can also be adjusted. In addition, it was found that the resin mixture has good film forming properties and moldability, and is easy to laminate. The reason for this is not clear, but the diffusion rate of the fragrance is transferred from the soft resin A part such as EVA, which has a slower desorption rate, to the faster thermoplastic resin B part, such as polyethylene, and the fragrance is transferred to the outer paper. It is thought that the fragrance is effectively volatilized into the atmosphere through the layer.

By the way, the biggest feature of the scented calendar of the present invention is that it is not only easy to print, but it also prevents the printing ink from melting and bleeding, unlike scented film or scented paper impregnated with a large amount of fragrance. There is no such thing. In addition, the scented calendar of the present invention has excellent writing properties, and notes can be written on it with a pen or ballpoint pen in the same way as on plain paper, and the ink written on it does not bleed.

The reason for this is that in the fragranced calendar of the present invention, most of the fragrance is thought to exist in the fragrance-containing thermoplastic resin layer, and the fragrance gradually desorbs from the surface of the resin layer and diffuses into the paper layer on the front side. and volatilizes. Therefore, the amount of fragrance present in the paper layer is very small, and therefore the fragrance component does not worsen the adhesion of printing ink or writing instrument ink, or dissolve or bleed them, resulting in clear print. It is believed that the condition can be maintained.

The great advantage of being able to print and write on it and not allowing letters or images to bleed is something that could not be achieved with conventional scented films or scented paper impregnated with a large amount of fragrance.

(g) Effects of the invention As mentioned above, the scented calendar of the invention has the advantage of being able to adjust functions such as fragrance strength and persistence, and has excellent properties such as printability, writability, and water resistance. In addition, by covering the product with a peelable, aroma-impermeable sheet, it is possible to maintain the fragrance for a long period of time without needlessly volatilizing the fragrance before use.

In addition, for daily or monthly calendars, it is not only possible to add different fragrances to match the design, but also to have a deodorizing effect or deodorizing effect depending on the place of use. Has many advantages.
