Abstract

PURPOSE:To attain the desired slow released and decrease in volume of an aromatic substance caused by time-dependent volatilization by wrapping a powdery aromatic or a liquid aromatic supported on an organic or inorganic carrier with a heat sealing viscose processed paper. CONSTITUTION:A viscose processed paper is prepared in the following manner: a sheet of combination paper, at least one surface thereof, is coated with a viscose solution with a roller coater or is soaked in the viscose solution, and is then processed in a solidification bath and further in a cellulose regeneration bath. The heat sealing viscose sheet prepared is made of cellulose film with pores, is 12-70g/m<2> in basis weight and 0.02-0.2mm in thickness and has an adequate air-permeability according to characteristics of an aromatic substance used and a desired duration time. A powdery aromatic may be used as it is, but a liquid aromatic is supported on an organic or inorganic carrier, and is then wrapped with the viscose paper. The aromatic constructed above has a desired slow released rate of the substance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a fragrance, and more particularly to a fragrance that imparts sustained release properties to a fragrance.

[Prior art and problems to be solved by the invention] A fragrance device used inside a building or a vehicle is a container in which a spongy body impregnated with a fragrance liquid is stored, and a lid with a spindle that can be inserted into and removed from the container. Some of the well-known types include those that are sealed and pulled up and evaporated, spray-type products that spray a perfume mixture, and synthetic resin sheets impregnated with perfume.

Recently, fragrances have come to be used in a wide variety of fields, and the forms in which they are used have also become more diverse. As an example, many fragrances are packaged in bags, and typical materials for such bags are paper and perforated synthetic resin sheets.

For example, an air freshener made by wrapping a fragrance in a water-repellent porous sheet made of polyolefin resin such as polyethylene or polypropylene (Japanese Unexamined Patent Publication No. 139346/1982).
The inner bag is formed by laminating paper on the outer surface of a polyolefin resin thin film with a wall thickness of 50 to 100 microns, which is impermeable to liquids and permeable to gases. A fragrance material made by sealing a perfume liquid inside a bag, and sealing this inner bag in an outer bag formed by laminating a thin synthetic resin film on the inner or outer surface of light metal foil (publication of Utility Model Publication No. 59-33406) , a packaging material in which one part is made of a breathable material such as Japanese paper or non-woven fabric coated with or affixed with a ventilation regulator such as polyethylene, and the other part is made of a see-through non-breathable material such as cellophane. Insect repellent and deodorant made by enveloping volatile chemicals (Utility Model Publication No. 52-16068)
No. 0 Publication) etc. are known. Further, Japanese Patent Publication No. 59-27783 discloses the use of petal-shaped calcium silicate and/or petal-shaped silica as a material to be volatilized while controlling the evaporation rate. However, in these methods, the moment the lid is opened, an excessively irritating fragrance is temporarily or partially evaporated, so that the fragrance itself quickly disappears.

Moreover, the containers are bulky and expensive, making it economically unsuitable to use several types of air fresheners in several rooms at the same time. It cannot be used satisfactorily from the viewpoint of radioactivity.

[Means for solving problems]

As a result of repeated research in order to eliminate the above-mentioned drawbacks and obtain an economical and easy-to-handle fragrance, the present inventors discovered that the conventional drawbacks could be improved by using viscose processed paper with heat-sealing properties. This discovery led to the completion of the present invention.

That is, the present invention provides a fragrance comprising a powdered fragrance or a liquid fragrance supported on an organic or inorganic carrier and packaged with viscose processed paper having heat sealability.

The viscose processed paper having heat-sealability used in the present invention is disclosed in Japanese Patent Application Laid-open No. 59-1798 and Japanese Patent Laid-Open No. 59-17
As disclosed in No. 99, a mixed paper made of hydrophilic fibers and thermoplastic fibers that are hydrophobic and have heat-sealability, a layer made of hydrophilic fibers, and a layer that is made of hydrophilic fibers and thermoplastic fibers that are hydrophobic and heat-sealable. A regenerated cellulose layer is formed on a laminated paper of layers made of thermoplastic fibers having sealing properties to the extent that the heat sealing properties of the thermoplastic fibers are not impaired. That is, at least one surface of the mixed paper and laminated paper is coated with a viscose liquid using a roll coater or the like, or is impregnated with the viscose solution, treated in a coagulation bath, and then treated in a cellulose regeneration bath. It will be done.

The heat-sealable viscose paper used in the present invention is an air permeability control type paper that has a cellulose film with fine holes, and has a basis weight of 12 to 70 g/
Preferably 18-60g/weight, thickness 0.02-0.
2 rtmO is preferable, and one with an appropriate air permeability may be selected depending on the nature of the fragrance and the desired duration.

In the present invention, when packaging fragrances with heat-sealable viscose processed paper, powdered fragrances may be used as is, but liquid fragrances may be supported on an organic or inorganic carrier. Further, powdered fragrances may also be used by being supported on an organic or inorganic carrier in an appropriate solvent. Examples of organic or inorganic carriers for carrying fragrances include polymer particles such as polyethylene, polypropylene, polyvinyl chloride, polyvinylidene chloride, polyamide, ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, activated carbon, and zeolite. Examples include silica gel, calcium silicate, white carbon, etc. In order to support the fragrance on the carrier, it is sufficient to mix the fragrance with the carrier at a ratio of 99.9 to 20:0.1 to 80, and sufficiently stir the mixture at a temperature of room temperature to 100°C.

Packaging of fragrances with viscose-treated paper having heat-sealing properties can be carried out by the following method. First, each pair of heat-sealable viscose processed paper is mechanically cut into appropriate sizes, and then an opening is left on the - side edge and three side edges are heat-sealed to form a bag. After a predetermined amount of a powdered flavor or a carrier carrying a flavor is continuously injected into this bag using an enclosing machine, the opening is heat-sealed to seal it. The fragrance thus obtained can impart the desired sustained release properties to the fragrance.

Incidentally, the fragrance can be stored for a long period of time by sealing it in an impermeable outer bag made of cellophane paper, vinylidene chloride thin film, etc. and keeping it at a low temperature.

Table 1, Table 2, for the floral fragrance KM-1120, there is an almost proportional relationship between the air permeability and the number of days it lasts, so you can predict the number of days it will last by determining the air permeability, or determine the desired number of days it will last. It is possible to choose a viscose-treated paper that has heat-sealing properties with good air permeability.
