These components are prepared by mixing the wax at 0.5 to 2 times the amount of the rosin, etc., therewith. Further, the content ratio of the cold volatile compound in the aromatic compound is preferably set at 10 to 30 wt.%.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup for producing a fragrance at a predetermined temperature.

[0002]

2. Description of the Related Art In general, instant coffee and coffee and tea sold in vending machines have little inherent aroma in this kind of beverage.

[0003] In addition, generally used paper cups have a slight odor, such as an adhesive or ink, and when the paper cup is used as a beverage container, the user may feel discomfort.

On the other hand, a cup in which a fragrance such as coffee scent or tea scent is encapsulated in a microcapsule which can be destroyed at 60 to 70 ° C. and applied to the outer surface thereof is disclosed in Japanese Utility Model Publication No. 60-115.
-38937.

When hot water of 70 ° C. or more is poured into the above-mentioned cup, the microcapsules are broken and a predetermined scent is generated.

[0006]

However, in this method, microcapsules having an average particle size of several μm to several tens μm are applied to the outer peripheral surface of a paper cup, and a strong scent is generated when hot water is poured. To do so, it is necessary to coat the entire circumference of the paper cup. And in such a form,
When boiling water is poured, the fragrance exudes from the broken microcapsules, so that the fragrance adheres to the hands and the user feels discomfort. Further, when the microcapsules are applied only to a part of the outer peripheral surface of the cup so as not to touch the hand, a strong scent is not generated even when hot water is poured. For this reason, it is difficult to secure a large amount of fragrance, a predetermined scent cannot be generated, and it is not practical.

Accordingly, an object of the present invention is to provide a fragrance cup which can hold a large amount of fragrance and can maintain the generation of fragrance without soiling hands.

[0008]

In order to solve the above-mentioned problems, the present invention comprises a room temperature volatile compound and a resin kneaded product which can be uniformly mixed with the compound, wherein the melting point of at least one component of the resin kneaded product is as follows. Of a fragrance composition having a temperature of 50 to 85 ° C. is attached to the lower surface of the bottom of the cup.

Since the package of the predetermined fragrance composition is provided on the lower surface of the bottom of the cup, a large amount of the normal-temperature volatile compound can be held in the cup, and sufficient fragrance can be emitted. In addition, since the package is provided on the lower surface of the bottom of the cup, there is no fear that the fragrance directly touches the hand.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

The fragrance cup 1 according to the present invention is shown in FIG.
(A) As shown in (b), a package 3 of the fragrance composition 2 composed of a room temperature volatile compound and a resin kneaded product is placed in a cup 4
Is adhered to the lower surface of the bottom of the.

The above-mentioned normal-temperature volatile compound is a compound which can be volatilized at normal temperature, that is, about 20 to 40 ° C., and which emits an aroma by volatilization of this compound. An example of this is a fragrance. In addition, this compound is, for example, wax or rosin or a derivative thereof (hereinafter, referred to as
It is called "rosin etc." ). At this time, in order to uniformly generate a fragrance, it is preferable that the compound can be uniformly mixed with the kneaded material.

[0013] Specific examples of the above-mentioned normal-temperature volatile compounds include:
Herbs typified by lavender and jasmine, and flavored fragrances typified by apple.

The above-mentioned resin kneaded material is a tacky composition that can be uniformly mixed with the above-mentioned volatile compound at normal temperature. The constituent components of the resin kneaded product include a predetermined wax, rosin, and the like.

The above-mentioned wax refers to a wax containing a hydrocarbon as a main component or an ester of a fatty acid and a higher alcohol and having a melting point of 50 to 85 ° C.
The reason why the wax having this melting point is used is that the wax is easily melted at the temperature of ordinary hot water used when brewing coffee or tea.

Examples of the above wax include stearic acid, rice wax and the like.

The above-mentioned rosin and the like refer to those obtained by removing terpin oil from raw pine tar, or those obtained by esterifying the same.
This rosin or the like has the ability to suppress the volatilization of the room-temperature volatile compound. Therefore, when kneaded with the wax, when the wax is in a solid state, that is, at room temperature, the volatile compound is hardly volatilized due to the volatilization suppressing ability of rosin and the like. Further, when the wax is melted, the ability to suppress volatilization of rosin and the like is reduced. At this time, the above-mentioned room-temperature volatile compound becomes easy to volatilize, and aroma is generated. Further, by mixing wax and rosin and the like, the above-mentioned volatile compound at a normal temperature is volatilized gradually. Therefore, under the molten state of the wax, generation of fragrance can be maintained.

Examples of the rosin include gum rosin, wood rosin, ester gum and the like.

The mixing ratio of the wax and the rosin is not particularly limited, but it is preferable to mix the wax in an amount of 0.5 to 2 times the rosin or the like. If it is less than 0.5 times, the volatilization suppressing ability of rosin and the like becomes high, and even at a predetermined temperature, it may be difficult to volatilize the above-mentioned room temperature volatile compound. On the other hand, when it exceeds twice, the ability to suppress volatilization of rosin and the like is reduced, and the above-mentioned normal-temperature volatile compound may be volatilized at room temperature.

[0020] The content ratio of the room-temperature volatile compound in the aroma composition is preferably 10 to 30% by weight. If the content is less than 10% by weight, the proportion of rosin and the like becomes relatively high.
The volatilization of the above-mentioned room-temperature volatile compounds is more strongly suppressed, and even when the wax is heated to melt the wax, almost no fragrance is released. On the other hand, when the content exceeds 30% by weight, the above-mentioned normal-temperature volatile compound can exert a plasticizing effect on rosin and the like, so that the volatilization-suppressing ability of rosin and the like is reduced, and the above-mentioned normal-temperature volatile compound is volatilized even at room temperature. Cases arise.

Known additives may be added to the fragrance composition 2 in addition to the above-mentioned resin kneaded product and room-temperature volatile compounds, as long as the effects of the present invention are not affected.

The fragrance composition 2 can be formed by any method. For example, there are a method of inserting the fragrance composition 2 into a mold having a predetermined shape, a method of dropping the fragrance composition 2 to obtain a droplet or a sphere, and the like.

The package 3 is a package in which the fragrance composition 2 is packed in a bag, and the granules of the fragrance composition 2 may be packed in the bag. May be filled into the bag in a molten state.

The bag constituting the packet 3 is not particularly limited as long as it is permeable to the gas of the above-mentioned volatile compound at normal temperature. Examples of the material of such a bag include paper, polyethylene, polypropylene, polystyrene, and a perforated aluminum film that can be opened. When the fragrance composition is filled in a molten state, it preferably has liquid impermeability in addition to gas permeability.

The package 3 is attached to the lower surface of the bottom of the cup 4. As a method of this sticking, an arbitrary method such as bonding with an adhesive can be used.

Since the package 3 is attached to the lower surface of the bottom of the cup 4, the cup 4 preferably has a space between the bottom of the cup 4 and the desk when the cup 4 is placed on a desk or the like. . The material of the cup 4 is not particularly limited, and examples thereof include paper and polypropylene.

The fragrance cup 1 according to the present invention can be manufactured as follows.

First, the above resin is melt-kneaded. Then
The room temperature volatile compound is added to the melt-kneaded product, and the mixture is uniformly mixed to obtain the fragrance composition 2. The fragrance composition 2 is poured into the bag in a molten state, or the fragrance composition 2 is pelletized or granulated and filled in the bag, or the fragrance composition 2 in the molten state is converted into porous particles. Impregnated,
The package 3 is obtained by filling the cooled bag in the bag. By affixing the package 3 to the lower surface of the bottom of the cup 4, the fragrance cup 1 is obtained.

Examples 1 to 6 The wax and rosin shown in Table 1 were melt-kneaded at the ratios shown in Table 1 at a temperature of 120 ° C. Next, the room temperature volatile compounds shown in Table 1 were added in the amounts shown in Table 1 and mixed uniformly. The obtained composition was formed into a sphere and cooled to obtain a granulated fragrance composition. So that the amount of the normal-temperature volatile compound becomes 0.2 g,
The obtained granular material 2 was stored in a paper bag to prepare a package 3, and was adhered to the lower surface of the bottom of the paper cup 4 as shown in FIGS. 1 (a) and 1 (b). 90 ° C. hot water was poured into the paper cup 4, and the state of aroma was examined. In Table 1, "mixing ratio" indicates the weight ratio of wax / rosin / room temperature volatile compound.

Comparative Example 1 Granules of the aroma composition obtained in Example 1 were pulverized so as to have an average particle size of 10 μm. This pulverized material was applied to the lower half so that the entire outer peripheral surface of the paper cup 4 was not sticky. 9 in this paper cup 4
Hot water at 0 ° C. was poured to check the state of aroma.

(Comparative Example 2) Granules of the aroma composition were obtained in the same manner as in Example 1 except that a water-soluble peach was used as the room-temperature volatile compound, to prepare a package. The package was adhered to the lower surface of the bottom of the paper cup, and hot water at 90 ° C. was poured to check the state of aroma.

[0033]

[Table 1]

As a result, in Examples 1 to 5, lavender fragrance was smelled for a long time after the hot water was supplied. In Example 6, the fragrance of apple was smelled for a long time.

On the other hand, in Comparative Example 1, the total amount of the fragrance composition applied to the outer peripheral surface of the paper cup was only 50 mg, although the mixing ratio was the same as in Example 1, so that even if hot water was supplied, Almost no lavender fragrance could be felt, and the appearance was extremely unsightly.

When peach which was incompatible with the resin mixture of Comparative Example 2 was used, a strong fragrance was emitted at room temperature.

[0037]

According to the present invention, at normal temperature, the volatilization of volatile compounds at normal temperature is suppressed, and no fragrance is generated. Then, when hot water is poured, the suppression of volatilization is eased, and fragrance is generated.

Further, since the space on the bottom lower surface of the cup is used, a large amount of the normal-temperature volatile compound can be held.

Further, when hot water is poured into the fragrance cup, fragrance is generated, and when drinking a beverage with the fragrance cup, the fragrance can be enjoyed.

Further, since the package is adhered to the lower surface of the bottom of the cup, the package is not visible from the outside and has good appearance.
