Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic cross-sectional view illustrating a multi-layer sheet structure of an incense patch according to an embodiment of the present invention.

Referring to Fig. 1, there is shown a fragrance patch 10 having a fragrance receiving portion 13 in which a fragrance is received between the upper and lower polymer sheets 10a, 10b. The two polymer sheets 10a and 10b are fusion bonded at the heat adhering portions 16 and 17 formed along the interface (or edge), thereby forming the fragrance accommodating portion 13. The two polymer sheets 10a and 10b are composed of a base sheet 10a and a release sheet 10b.

The base sheet 10a has a structure in which a two-ply polymer resin sheet, that is, an inner sheet 12 and an outer sheet 11 are laminated. The outer sheet 11 may be a thermoplastic material which is gas impermeable and has a relatively high melting point or may be a thermosetting material resistant to heat. For example, the outer sheet 11 may be a PET (polyethylene terephthalate) sheet having a melting point of 250 ° C to 290 ° C. The inner sheet 12 is made of a gas-permeable and thermoplastic material, and is preferably made of a material that can be easily fused by, for example, a high-frequency fusion splicer. For example, the inner sheet 12 may be a polyurethane sheet having a melting point of 75 ° C to 150 ° C.

A primer may be interposed between the inner sheet 12 and the outer sheet 11 forming the base sheet 10a to increase adhesiveness or bonding strength. However, it is also possible to use a laminated sheet between the PET sheet and the polyurethane sheet, without applying any adhesive or primer, while pressing so as to eliminate the air layer.

The release sheet 10b has a structure in which a two-ply polymer resin sheet, that is, an inner sheet 14 and an outer sheet 15 are laminated, similar to the base sheet 10a, (14) is joined so that it can be peeled off with a nail or fingertip of a person. The outer sheet 15 may be a thermoplastic material that is gas impermeable and has a relatively high melting point, or may be a thermosetting material that is heat resistant. For example, the outer sheet 15 may be a PET (polyethylene terephthalate) sheet having a melting point of 250 ° C to 290 ° C. The inner sheet 14 is made of a gas-permeable, thermoplastic material, and is preferably made of a material that can be easily fused by a high-frequency fusion splicer, for example. For example, the inner sheet 14 may be a polyurethane sheet having a melting point of 75 ° C to 150 ° C.

Between the inner sheet 14 and the outer sheet 15 constituting the peeling sheet 10b, a primer such as a releasing agent for enhancing the peelability may be interposed. However, it is also possible to use a laminated material between the PET sheet and the polyurethane sheet while pressing them together so as to eliminate the air layer without any mold release agent or primer.

The fragrance accommodating portion 13 in which the fragrance agent is accommodated is formed in a predetermined closed line (e.g., a circle, an ellipse, a quadrangle, or a rectangle) so as to form a predetermined space in the base sheet 10a and the inner sheets 12, 14 of the release sheet 10b. , A peanut, a character, or an irregular shape, etc.).

In the fragrance patch 10 having such a structure, the fragrance ingredient contained in the fragrance accommodation portion 13 and usually dissolved in a solvent such as alcohol may be released while being vaporized together with the alcohol component. The gaseous form and alcohol components pass through the gas permeable inner sheets 12 and 14, but the outer sheets 11 and 15 can not pass through. Therefore, the fragrance component in the fragrance accommodation portion 13 in the configuration shown in Fig. 1 can not be diverted to the outside. Therefore, the incense patch 10 can provide the advantage that it can be circulated or stored for a long time in the form shown. In order to diffuse outwardly from the fragrance accommodating portion 13, any one of the gas-impermeable outer sheets 11, 15 is peeled so that any one of the gas permeable inner sheets 12, 14 is exposed to the outside air There is a need. For this purpose, when using the purchased fragrance patch 10, the user can peel off the outer sheet 15 of the release sheet 10b by hand.

Fig. 2 is a flow chart schematically showing a method of manufacturing the fragrance patch of Fig. 1;

2 (a) shows a case where the base sheet 10a and the release sheet 10b are laminated or joined together, and the lines of the fragrance bag shape are thermally adhered by using the high-frequency fusion splicer 20. Then, the joint portion 16 schematically shown in Fig. 2 (b) is closed, and the fragrance bag 13a, which is partially open, can be formed. Then, a liquid aromatic agent can be injected into the fragrance bag 13a. Then, as shown in Fig. 2 (c), the portion of the fragrance bag 13a filled with the fragrance can be sealed by using the high-frequency fusion splicer 20 again. As a result, as shown in Fig. 2 (d), the fragrance patch 10 in a state of containing the fragrance in the fragrance storage portion 13 formed by joining the two sheets of the upper and lower sheets by the joining portions 16, 17, Can be prepared.

FIG. 3 is a schematic cross-sectional view for explaining a state in which one outer sheet is peeled off when the incense patch of FIG. 1 is actually used.

Referring to Fig. 3, an incense patch 30 in use is shown. The incense patch 30 in the use state shows a state in which the outer sheet 15 of the release sheet is peeled off from the incense patch 10 during storage and distribution in Fig. In this case, the liquid aromatic agent filled in the fragrance storage portion 13 tends to evaporate slowly as it passes through the gas permeable inner sheets 12, 14 and diverges to the outside as time elapses. In the illustrated example, since the gas-impermeable outer sheet 11 is joined to the inner sheet 12 on the lower side, the fragrance component can not permeate the outer sheet 11. On the other hand, since the upper gas permeable inner sheet 14 is exposed to the outside air as it is, the aromatic component passes through the upper inner sheet 14 and radiates to the outside air.

This incense patch 30, for example, when the inner sheets 12 and 14 are made of thermoplastic and gas permeable polyurethane, the polyurethane may melt in the alcohol component over time and become obtuse. However, since the outer sheet 11 such as PET sheet resistant to alcohol components has no shape change over time, the shape of the incense patch 30 is not so deformed, / RTI >
