Description

  The present invention relates to a case for storing paints and crayons, and relates to a case for suppressing the smell of paints and crayons in the case.

Conventionally, as a method for suppressing the odor of a substance, as disclosed in Patent Document 1, a part of the surface of a sheet contains a porous body carrying a metal ion and is used for deodorization and / or removal. Bacteria sheets are known.
JP 2007-82974 A

  However, when the deodorizing and / or disinfecting sheet of Patent Document 1 is placed in a case such as a paint or crayon, the odor of the paint or crayon can be suppressed, but it is necessary to increase the number of parts separately. In addition, there is a method of attaching a porous body carrying metal ions in the case, but it is necessary to add a fixing material separately in order to fix the porous body to the case. Then, the pores of the porous body are blocked with the fixing material, and the deodorizing action is impaired. Therefore, in order to strengthen the deodorizing action, if the amount of the porous body is increased, the color tone becomes opaque. Therefore, it is necessary to provide a place for attaching the porous body when it is attached in the case. At this time, the inner surface of the case of the paint and crayon is used to indicate precautions such as usage, and as a result, a sufficient amount can be attached to adsorb the odor of the paint and crayon. There wasn't.

  That is, the gist of the present invention is a paint or crayon case in which at least cyclodextrin is adhered to the inner surface of the case.

  The cyclodextrin molecule can be complexed by incorporating a hydrophobic odor molecule smaller than the inner diameter of the cyclodextrin or a part of the hydrophobic odor molecule into the lipophilic portion of the cyclic structure. Then, the hydrophobic odor component molecule generated from the substance stored in the case or a part of the hydrophobic odor component molecule is incorporated and combined to suppress the odor component generated from the substance stored in the case. it can. Therefore, the smell of paint and crayons can be suppressed. Cyclodextrin has a film-forming action and can be fixed on the inner surface of the case. Further, since it is transparent, it can give an effect of suppressing the smell of paint and crayon over the entire surface of the case.

Cyclodextrins are cyclic oligosaccharides.
In the present invention, one or more of α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin can be used, and they may have a substituent. The cyclodextrin having a substituent can be used without any particular limitation. For example, hydroxyl alkylated cyclodextrin, alkylated cyclodextrin, glucoxylated cyclodextrin, aminated cyclodextrin, carboxymethylated cyclodextrin, at least part of the glucose residue is hydroxyethyl, 2-hydroxypropyl, 2,3- Cyclodextrin polymers polymerized with a crosslinking agent such as cyclodextrin, epichlorohydrin or polyvalent glycidyl ether having hydrophilic functional groups such as dihydroxypropyl, 2-hydroxybutyl, 2-hydroxyisobutyl, diethylaminoethyl, trimethylammoniumpropyl, Use one or more of branched cyclodextrins having branched side chains such as glucose and malnose, highly branched cyclic dextrins, etc. It can be.

  Examples of the shape of the case for the paint and crayon include those known in the art. Specifically, a case in which an inner box containing the paint and crayon is covered with an outer box serving as a lid. A case in which a removable inner box is inserted into a sleeve type outer box. Examples include a case where a paint, a crayon housing and a lid are connected by a hinge. Any material can be used.

As a method of attaching cyclodextrin to the inner surface of the case for paints and crayons, add a solvent to cyclodextrin to create a cyclodextrin solution, spray the cyclodextrin solution toward the inner surface of the case, or apply it with a brush, etc. The method of making it dry is mentioned. Solvents for preparing cyclodextrin solutions include hydrocarbons such as pinene, seylene and santalen, alcohols such as methanol, ethanol and isopropyl alcohol, aliphatic alcohols such as propylene glycol and dipropylene glycol, terpineol and isoborneo Terpene alcohols such as santaterben alcohols such as santalol, cedrol and lambuterol, aromatic alcohols such as phenylethyl alcohol and cinnamon alcohol, phenols such as paracresol and thymol, phenyls such as benzylbenzoate and isoeugenol Ethers, aliphatic aldehydes having a C8-C13 hydrocarbon chain such as a gourmet, terpene aldehydes such as citral and citronella, benzaldehyde , Aromatic aldehydes such as phenylpropyl aldehyde, cyclic ketones such as cis jasmon and menthone, lactones such as nanolactone, esters such as benzyl acetate and geranyl acetate, nitrated compounds such as indole and methylanthraanilate, Examples thereof include distilled water. These solvents are used alone or in combination.
The inner surface of the case is an outer case and an inner case which are parts of the case, or an inside of the case surrounded by the housing portion and the lid.

  In addition, a fragrance | flavor can also be used. When using a fragrance, the fragrance may be added to the cyclodextrin solution and sprayed on the inner surface of the case or applied with a brush or the like.

A paint is a so-called liquid drawing material, water as a solvent, pigment as a coloring component, natural resin, synthetic resin, grain, glue, and other resins as a fixing agent, and stabilizer, desiccant, etc. as other auxiliary components. It is a blended product and put in a case made of tin or polyethylene.
Crayon is a so-called solid drawing material, pigment as coloring component, petroleum wax such as paraffin wax, microcrystalline wax and / or plant or animal wax such as carnauba wax, tree wax, beeswax as molding material. In addition, it is a combination of extender pigments and oil components such as petroleum jelly, spindle oil, and mineral oil as auxiliary components. After forming into a columnar shape, it is wrapped in paper and stored in a case.

An example will be described based on the drawings.
FIG. 1 is a perspective view of a case in which a paper inner box 2 is covered with a paper outer box 1 serving as a lid. The inner box 2 is a box for storing paints and crayons. In order to align the paint and crayons, the inner box 2 can be provided with a partition or a tray inside the inner box 2. The outer box 1 is a box that covers the inner box 2 and serves as a lid. The dimensions are such that there is no backlash when the inner box 2 is covered with the outer box 1 and can be removed freely. As an example of the position where cyclodextrin is attached, the inside 3 of the ceiling portion of the outer box 1 is shown by dots. The amount of cyclodextrin deposited is about 0.01 to 0.3 gram for the entire case. When using a fragrance | flavor, it shall be 0.1%-50% with respect to the adhesion amount of cyclodextrin.

  FIG. 3 is a perspective view of a case in which a paper inner box 2 that can be inserted and removed is inserted into a paper sleeve-type outer box 4. FIG. 4 is a component diagram in which the sleeve-type outer box 4 of FIG. 3 is developed. The sleeve type outer box 4 is a cylindrical part for inserting the inner box 2 into a lid. The sizes of the inner box 2 and the sleeve type outer box 4 are not loose and are in contact with each other so that they can be removed freely. As an example, the position where cyclodextrin is attached is shown in FIG. The amount of cyclodextrin deposited is about 0.01 to 0.3 gram for the entire case. When using a fragrance | flavor, it shall be 0.1%-50% with respect to the adhesion amount of cyclodextrin.

  FIG. 5 shows a case in which a polypropylene paint, a crayon housing 6 and a polypropylene lid 7 are connected by a polypropylene hinge 8. The lid 7, the paint, and the crayon housing 6 are not opened during storage by a method such as providing a fitting portion or fixing with a hook. The inside 9 of the ceiling part of the lid 6 is indicated by dots by taking the position where the cyclodextrin is attached as an example. The amount of cyclodextrin deposited is about 0.01 to 0.3 gram for the entire case. When using a fragrance | flavor, it shall be 0.1%-50% with respect to the adhesion amount of cyclodextrin 3. FIG.
