Description

  TECHNICAL FIELD The present invention relates to a water-proof sheet used for packaging, surface protection of various articles, a safety container for storing food, detergent, reagent, chemicals, etc., an aroma container using the same, and an aroma container storage device. .

Conventionally, polyvinyl chloride and polyethylene sheets have been used as sheets for packaging foods, detergents, reagents, chemicals, and the like. However, the sheets function only when the contents are transported, and the waste remains in the environment, which is a problem.
Therefore, the use of sheets that are reduced in volume as the used sheets themselves gradually collapse and that do not easily remain in the environment has begun to be studied. As such sheets, those made of water-soluble polymers such as starch, polyvinyl alcohol, and carboxymethyl cellulose are known.
However, these sheets have a problem of lacking water resistance.

Also, as containers for storing solids such as granular materials, liquids such as chemicals and perfumes, gels, etc., glass or ceramic ampoules, bottles, etc. that are excellent in water resistance and chemical stability and are stable against chemicals, etc. It is used.
As such an ampoule, for example, a breakable glass ampoule in which a chemical such as a chemiluminescent solution described in (Patent Document 1) and (Patent Document 2), a fragrance, or the like is enclosed is known.
Further, as a container formed so as to be capable of brittle fracture without exhibiting almost plastic deformation, “Patent Document 3” includes “sealed packaging container using a composite material composed of light or heavy calcium carbonate and an organic binder”. Are listed.
JP 2003-250630 A JP 2003-229001 A Japanese Patent Laid-Open No. 3-98851

However, the above conventional techniques have the following problems.
(1) In order to take out drugs and fragrances from the glass ampules described in (Patent Literature 1) and (Patent Literature 2), the glass ampules are broken by applying tensile stress by bending the glass ampules. Extremely sharp fragments were formed, and the skin and mucous membranes were sometimes damaged when touched.
(2) Therefore, the glass ampoule must be stored in an outer container made of polyethylene, polypropylene or the like so that the fragments do not directly touch the skin, and if the fragments break through the outer container, they are stored in the outer container. However, since the skin and the like are damaged, it is necessary to increase the mechanical strength by increasing the thickness of the outer container so that fragments do not penetrate the outer container, and there is a problem that the degree of freedom in designing the outer container is lacking. .
(3) In the glass ampoule in which the fragrance is enclosed (Patent Document 1), in order to prevent the glass fragments from jumping out from the divergence port formed in the outer container in order to volatilize the fragrance, felt or the like is provided inside the divergence port. However, it has a problem that it lacks productivity.
(4) Since glass ampules must be covered with an outer container in order to protect the skin and the like from debris, there is a problem that it is difficult to use the glass ampule itself for decoration like a perfume bottle. .
(5) The sealed packaging container described in (Patent Document 3) is a container for packaging solid materials such as toys. When a liquid such as a chemical or a perfume, a gel, or the like is contained, moisture is absorbed by calcium carbonate and is water resistant. Had the problem of lacking.

The present invention solves the above-mentioned conventional problems, is excellent in water resistance and solvent resistance, and the sheet itself after use is easy to disintegrate in the environment, and is difficult to remain in the environment and has few waste disposal problems. The object is to provide a water-resistant sheet with excellent maintainability.
In addition to being excellent in water resistance and solvent resistance, it can be broken relatively easily when bent or crushed with fingers, and the broken fracture surface is not sharp, and cracks are difficult to propagate, making it difficult for fragments to form. It aims at providing the safety container which is excellent in safety.
In addition to being excellent in water resistance and solvent resistance, it can be broken relatively easily when bent or crushed with fingers, and since the sealed fragrance liquid comes into contact with the outside air, it can release the fragrance to the surroundings and break it. Another object of the present invention is to provide a fragrance container that is excellent in safety because it is not sharp and has excellent safety, and the fragrance container itself can be used for decoration like a perfume bottle.
In addition, by screwing the lid member after the fragrance container is stored in the storage member, the fragrance portion destroys the fragrance container and the fragrance liquid comes into contact with the outside air. It is an object of the present invention to provide a fragrance container storage device that can release fragrance to the surroundings by volatilizing water or leaking fragrance liquid.

In order to solve the above conventional problems, the water-resistant sheet, the safety container, the fragrance container using the same, and the fragrance container storage tool of the present invention have the following configurations.
The water-resistant sheet according to claim 1 of the present invention comprises a base sheet formed of a hydrophilic polymer compound, and a silicon compound coating layer formed on one or both sides of the base sheet. have.
With this configuration, the following effects can be obtained.
(1) Since the silicon compound coating layer is formed on one side or both sides of the substrate sheet, the hardness can be increased and the rigidity can be increased, and the smoothness of the surface can be further increased and water resistance can be imparted.
(2) Since the silicon compound coating layer is excellent in adhesion to a base sheet formed of a hydrophilic polymer compound, a dense silicon compound coating layer can be formed and the water resistance is excellent.
(3) Since the coating thickness of the silicon compound coating layer can be increased, the mechanical strength can be increased, and mechanical properties such as rigidity can be freely set by the coating thickness, and the flexibility is excellent.

  Here, as the hydrophilic polymer compound, one having a functional group such as a carboxyl group, a sulfone group, a hydroxyl group, an amide group, an ether group in the main chain or side chain is used. This is because the adhesion with the silicon compound coating layer is good. Specifically, hydrophilic cellulose derivatives such as methyl cellulose, carboxymethyl cellulose, hydroxy cellulose; polyvinyl alcohol derivatives such as polyvinyl alcohol, vinyl acetate-vinyl alcohol copolymer, polyvinyl acetal, polyvinyl formal, polyvinyl benzal; gelatin, casein, Natural polymer compounds such as gum arabic and shellac; sugars such as starch; hydrophilic polyester derivatives such as partially sulfonated polyethylene terephthalate; hydrophilic such as poly-N-vinyl pyrrolidone, polyacrylamide, polyamide indazole and polyvinyl pyrazole 1 type or multiple types of polyvinyl acetate etc. which are soluble in alkaline aqueous solution etc. are used.

  A base material sheet can be shape | molded by the thickness of about 5-300 micrometers according to a use by various methods, such as a casting method, an extrusion method, and a gel film forming method.

As the silicon compound, silanol, alkoxysilane, hydrosilane, aminosilane, silanol, organosilicon compound such as siloxane generated by hydrolysis of aminosilane, or alkali silicate aqueous solution such as water glass is used. A transparent silicon compound coating layer can be formed by drying or hydrolysis after applying a liquid silicon compound to the substrate sheet by dipping or spraying, a gravure coating method, a roll coating method or the like. Even if there are pores on the surface of the base sheet, it penetrates into the pores by capillary action, so that the base sheet and the silicon compound coating layer can be brought into close contact with each other.
The thickness of the silicon compound coating layer is preferably 5 to 50 μm. As the silicon compound coating layer becomes thinner than 5 μm, it is difficult to increase the rigidity of the base sheet, and even if the water-resistant sheet is bent or twisted, it becomes difficult to break only by bending. There is a tendency that it is difficult to uniformly coat the surface and it becomes difficult to impart water resistance and oil resistance, etc., and as it becomes thicker than 50 μm, the drying rate tends to be slow and productivity tends to be lacking. Is also not preferred.

The water-resistant sheet of the present invention can be used as a sheet for packaging foods, detergents, reagents, chemicals and the like, and for protecting the surface of various articles. In addition, it can be processed into a tube or the like for packaging cosmetics, toothpastes, and the like.
When producing a water-resistant sheet that can be ingested with packaged foods, etc., hydrophilic polymer compounds include natural polymer compounds such as gelatin, casein and shellac, saccharides such as starch, and oral oral substances such as polyvinyl alcohol derivatives. Use ingestible.

Invention of Claim 2 of this invention is a water-resistant sheet | seat of Claim 1, Comprising: Aggregate particle | grains are 15-70 volume parts with respect to 100 volume parts of said base material sheets, Preferably it is 25-60 volume parts. It has the structure mix | blended with the said base material sheet in the ratio.
With this configuration, in addition to the operation obtained in the first aspect, the following operation can be obtained.
(1) Since the aggregate particles are blended in an amount of 15 to 70 parts by volume with respect to 100 parts by volume of the base sheet, the base sheet becomes brittle. Between the hydrophilic polymer compound or the aggregated particles and the hydrophilic polymer compound are easily cracked, and the fractured surface is not sharp because the surface of the aggregated particles or the hydrophilic polymer compound is exposed, In addition, since cracks are difficult to propagate, it is difficult to form debris and is excellent in safety.

Here, the aggregate particles are made of glass such as glass beads, made of metal oxide such as silica powder and alumina powder, made of synthetic resin such as acrylic resin and polyamide, iron, low carbon steel, silicon steel, permalloy, One or more magnetic materials such as Sendust, KS steel, MK steel, Fe—Co alloy, Cu—Ni—Fe alloy, Fe—Cr—Co alloy, etc., which are formed in a spherical, flake or hollow shape. Used. Moreover, what modified the surface of the aggregate particle | grains with the silanol group etc. can also be used. This is because the adhesive strength with the hydrophilic polymer compound can be increased.
Glass and synthetic resin aggregate particles can be transparent or translucent, and metal oxide aggregate particles can be white, so the base sheet can be transparent or translucent, and colored You can also enhance the decoration.
Aggregate particles formed of a magnetic material are brown or black and have poor decorative properties. However, a base material sheet that can be magnetized can be obtained, and applications can be expanded.
In the case of producing a water-resistant sheet that can be taken together with packaged foods or the like, as aggregate particles, those that can be taken orally such as silica powder, alumina powder, and other metal oxides are used.

  As an average particle diameter of aggregate particle | grains, 0.2-100 micrometers is used suitably. As the particle size becomes smaller than 0.2 μm, the aggregate particles tend to aggregate and become lumpy, and aggregate particles that are not bonded with the hydrophilic polymer compound tend to be generated and defects tend to occur. Since the surface irregularities are conspicuous, and the aggregate particles tend to drop off and defects tend to occur, neither is preferable.

  The base sheet can be produced by various methods such as a casting method and an extrusion method after kneading the hydrophilic polymer compound and the aggregate particles. In addition, after the surface of the aggregate particles is coated with a hydrophilic polymer compound, the aggregate particles coated with the hydrophilic polymer compound can be formed by press molding or the like.

  In addition, the tendency for a base material sheet to become hard is seen as the compounding quantity of the aggregate particle with respect to a base material sheet increases, and the base material sheet tends to become soft and flexible as the compounding quantity decreases. . Further, as the amount of the aggregate particles with respect to 100 parts by volume of the base material sheet exceeds 60 parts by volume, the bond between the aggregate particles becomes incomplete, and the mechanical strength of the base material sheet tends to decrease, 25 As the capacity decreases, the properties as a polymer compound become stronger, and even when the water-resistant sheet is bent or twisted with fingers, the amount of elastic deformation increases and it tends to be difficult to break. In particular, if the amount is less than 70 parts by volume or more than 15 parts by volume, these tendencies become remarkable, so that neither is preferable.

As the porous substrate sheet, a nonwoven fabric made of a hydrophilic polymer compound such as a hydrophilic cellulose derivative such as pulp or rayon, a polyvinyl alcohol derivative or a hydrophilic polyester derivative is used. As such a nonwoven fabric, those made by various production methods such as spunbond and meltblown are used.
The basis weight of the porous substrate sheet made of a nonwoven fabric is preferably 25 to 70 g / m ² . When the basis weight is smaller than 25 g / m ^2, the tensile strength and tear strength of the nonwoven fabric are small. For example, when used as an agricultural sheet or as a house lining curtain, it may be broken by the tension when it is repeatedly opened and closed by an automatic switch. There arises a problem that the heat retention effect is lowered. On the other hand, when the basis weight is larger than 70 g / m ² , the light transmittance is insufficient, and when used as an agricultural sheet, there is a problem that the growth of crops is inferior, and the weight increases and the handling property is not preferable.

I understood it.

(Comparative Example 1)
A paste was prepared by adding 65 parts by weight of ethanol to 50 parts by weight of polyvinyl alcohol (manufactured by Kuraray, trade name: RS polymer, LM10HD). This paste is applied to a stainless steel mold having an inner wall of 10 mm and a length of 50 mm and dried in a vacuum, and then the mold is removed and a bottomed cylinder having an outer diameter of 10 mm, a length of 50 mm and a thickness of 30 μm. A container of Comparative Example 1 was obtained.

(Evaluation of solvent resistance)
When 1 mL of aromatic liquid mixed with lavender oil and ethanol was injected into the containers of Experimental Examples 1 to 7 and Comparative Example 1 from the opening at one end, the container of Comparative Example 1 was dissolved in the aromatic liquid and kept in shape. I could not. In addition, the safety containers of Experimental Examples 1 to 7 were infused with aromatic liquid, sealed at one end with silicone rubber, and left in a room at 20 ° C. for one month or longer. The aromatic liquid was accommodated while being kept.
From the above, according to this experimental example, the safety container in which the silicon compound coating layer mainly composed of the organosilicon compound is formed on the inner surface of the base material container has a barrier function such as moisture and solvent on the base material container. It has been clarified that the water resistance, solvent resistance, and the like can be improved by imparting them.
In addition, it turned out that the safety container of Experimental example 5 is fragile, and mechanical strength is small compared with the safety container of another Experimental example. This is presumed to be because 73 parts by volume of aggregate particles are contained in 100 parts by volume of the base container, and the binding force between the aggregate particles by the hydrophilic polymer compound is small.

(Evaluation of brittle fracture)
Holding both ends of the safety container of Experimental Examples 1 to 7 in which the aromatic liquid was sealed and the container of Comparative Example 1 (which does not contain the aromatic liquid) with the left and right fingertips, and bending them, Experimental Examples 1 to 5 and 7 The side wall of the safety container was broken, and the aromatic liquid inside could be leaked from the broken side wall. It was found that the fracture surface was not sharp and almost no debris was generated. On the other hand, the container of Comparative Example 1 and the safety container of Experimental Example 6 were deformed even when bent, and could not be broken. Moreover, it turned out that the safety container of Experimental Example 7 is hard to break compared with the safety containers of Experimental Examples 1-5. It was guessed that the content of aggregate particles in the base material container was small.
Furthermore, when the broken safety containers of Experimental Examples 1 to 5 and 7 were immersed in the extracted aromatic liquid, the base container of the safety container could be dissolved and collapsed in the aromatic liquid.
From the above, according to the present experimental example, the hardness can be increased by forming the silicon compound coating layer on the base material container, and the blending amount of the aggregate particles with respect to 100 parts by volume of the base material sheet is 15 to 70. Since the safety container can be made brittle by making it into a capacity part, if the safety container is bent or twisted with fingers, the safety container can be broken brittlely, and the broken fracture surface is not sharp, It was also found that because cracks are difficult to propagate, it is difficult to form debris and has excellent safety.
In addition, if a silicon compound coating layer that does not easily react with the contained material is formed on the inner surface of the base material container and the base material container is formed of a hydrophilic polymer compound that is easily dissolved in the contained material, the contained material leaks out and is a safety container. It was clarified that the safety container can be collapsed when the hydrophilic polymer compound in the base material container is dissolved in the storage material.

  The present invention relates to a water-proof sheet used for packaging, surface protection of various articles, etc., a safety container for storing food, detergent, reagent, chemicals, etc., a fragrance container using the same, and a container for fragrance containers. In addition to being excellent in solvent resistance, the sheet itself after use is easy to disintegrate in the environment, and it is possible to provide a water-resistant sheet that is excellent in environmental conservation and hardly remains in the environment and has few waste disposal problems. Safety container with excellent safety and solvent resistance, and can be broken relatively easily when bent or crushed with fingers, and because the broken fracture surface is not sharp, and cracks are difficult to propagate, making it difficult for fragments to form. In addition to being excellent in water resistance and solvent resistance, it can be broken relatively easily when bent or crushed with fingers, and since the enclosed fragrance comes in contact with the outside air, it releases fragrance to the surroundings. In addition, since the broken fracture surface is not sharp, it is excellent in safety, and the aromatic container itself can be used for decoration like a perfume bottle etc. After the fragrance container is housed in the cap, the lid member is screwed, etc., so that the rupture part breaks the fragrance container and the fragrance liquid comes into contact with the outside air. It is possible to provide a fragrance container container that can release fragrance to the surroundings by leaking fragrance liquid.
