Description

[Technical field]

[0001] The present invention relates to an anti-mite bag that isolates articles used by humans from mites that affect the human body, thereby reducing their effect on the human body. [Background technology]

[0002] Recently, with the improvement of living environments and the progress of luxury housing, the inhabitation of many nuisance pests, mainly mites, has been recognized. Such nuisance pests are believed to cause skin diseases, asthma, etc., and therefore there is a strong demand for their control.

[0003] Conventional methods for controlling such nuisance pests include suction removal with a powerful vacuum cleaner, as well as a method in which an anti-mite sheet that combines a mite attractant sheet containing a mite attractant and an adhesive layer is placed under tatami mats, carpets, or bedding, which are suitable habitats for these nuisance pests, or near the carpet (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-202062 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the method of exterminating nuisance insects by disposing an anti-mite sheet that combines a mite attractant sheet and an adhesive layer as described above, the nuisance insects are first collected on the anti-mite sheet and then exterminated, and when used on bedding such as pillows, the nuisance insects will gather on the anti-mite sheet while a person is sleeping, which psychologically disturbs a good night's sleep. In addition, the anti-mite sheet that combines a mite attractant sheet and an adhesive layer captures the nuisance insects and is then discarded, but after the anti-mite sheet is discarded, it returns to its original state, which creates the problem that it is difficult to provide a long-term anti-mite effect.

[0006] In view of the above technical problems, the present invention aims to provide an anti-mite bag that can achieve a long-term anti-mite effect without collecting nuisance pests. [Means for solving the problem]

[0007] In view of the above-mentioned technical problems, the anti-mite bag of the present invention has a bag body provided with an opening and a closing part that allows the opening to be opened and closed, and is characterized in that the bag body is made of a main sheet material having anti-mite effect.

[0008] The anti-mite bag of the present invention has an anti-mite effect in the bag body, and since the bag body forms a closable bag, it can be arranged to encase target items in which nuisance pests can live, such as bedding, cushioning, cushions, parts of furniture, clothing, etc. This kills nuisance pests due to the anti-mite effect of the bag body, suppresses the movement of nuisance pests to the target items in which they can live, and at the same time prevents the spread of nuisance pests from the target items in which they can live.

[0009] The closure portion allows the inside and outside of the bag body to be opened and closed, and can be structured so that the end of the bag body on the opening side is made longer and the bag body itself is folded over to close the opening, or it can be structured so that it is closed by running a string or tape along the vicinity of the opening of the bag body and tightening the string like a drawstring on a drawstring bag, or it can be structured so as to have adhesive tape, snap buttons, zippers, hook-and-loop fasteners, etc.

[0010] The bag body may be a sheet material having an anti-mite effect, which is a carrier carrying an anti-mite agent, and examples of the carrier include inorganic (porous) carriers such as paper, woven or nonwoven fabric, wood pulp board, wood pulp grains, porous organic molded bodies such as porous cellulose particles (trade name: Viscopearl), kaolin, talc, calcium silicate particles (trade name: Fluorite), calcium carbonate particles, silica stone, silica sand, ceramics, etc., and films or solid or fibrous molded bodies made of polyethylene, polypropylene, polyester, ABS, ethylene / vinyl acetate copolymer (EVA), ethylene / methyl methacrylate copolymer (EMMA), styrene-based diblock polymer, styrene-based triblock polymer, thermoplastic resin elastomer (TPE, TPO), etc., and may have a structure consisting of a single substance or multiple layers of these. Furthermore, as the carrier, fibers made of acrylonitrile, vinylon, vinyl chloride, vinylidene chloride, polyurethane, and non-dyed nylon may be used instead of the above-mentioned polyol-based fibers. The anti-mite function imparting agent can be incorporated into the carrier by various methods such as dropping, coating, immersion, kneading, etc. In this specification, the term "anti-mite" is used in a broad sense and refers to many functions such as killing mites, repelling mites, preventing mites from invading, and inhibiting mites' behavior.

[0011] Examples of anti-mite agents supported on the main sheet material include inorganic compounds such as boric acid ceramics that release B2O3, and ceramics with copper, silver, platinum, or a mixture of these supported on the surface, using polyester fibers as the support. Composite ceramics can also be used, such as composite ceramics made by mixing magnesia and serpentine, or composite ceramics made by mixing magnesia, zinc oxide, silica, and titanium, or composite ceramics made by mixing magnesia, silica, and calcium oxide.

[0012] Naturally derived anti-mite agents can also be used, such as essential oils from cedar, cypress, red pine, bay cypress leaves, bay cedar, and bay pine, with Yakusugi, Shinobuhiba, and Ogonshinobuhiba being particularly effective, and essential oils from other trees such as Todomatsu and Yezo pine, eucalyptus, melaleuca, fig leaves, and horse chestnut can also be used as anti-mite agents. Furthermore, natural essential oils such as peppermint oil, lemon eucalyptus oil, and lavender oil, which contain anti-mite components that have a mite repellent effect, can also be used.

[0013] Examples of organic anti-mite agents include organic compounds such as amide compounds, thiocyanate compounds, carboxylate compounds, and bornyl alcohol compounds. Specific examples include cinnamyl acetate, menthyl acetate, citronellol, eugenol, perilla aldehyde, anisaldehyde, p-menthane-3,8-diol, methyl salicylate, benzyl salicylate, phenyl salicylate, hexyl salicylate, cyclohexyl salicylate, amyl benzoate, isoamyl benzoate, hexyl benzoate, cyclohexyl benzoate, cis-3-hexenyl benzoate, benzoic acid, benzoyl benzoic acid, ... Examples of the isomer include benzyl sebacate, diethyl sebacate, dipropyl sebacate, dibutyl sebacate, diisopropyl sebacate, diethyl adipate, dipropyl adipate, dibutyl adipate, dimethyl phthalate, diethyl phthalate, dipropyl phthalate, dibutyl phthalate, diamyl phthalate, dibutyl succinate, dibutyl maleate, farnesyl acetone, and hexyl cinnamaldehyde. When optical isomers or geometric isomers exist, all of the individual isomers and possible mixtures of isomers are included in the present invention.

[0014] Among these, benzyl salicylate, phenyl salicylate, diisopropyl sebacate, dibutyl phthalate, and from the viewpoint of safety, cinnamyl acetate, p-menthane-3,8-diol, benzyl salicylate, dibutyl sebacate, diisopropyl sebacate, and benzyl benzoate, which are derived from natural plant components, are preferred, and p-menthane-3,8-diol, benzyl salicylate, dibutyl sebacate, diisopropyl sebacate, and benzyl benzoate are particularly preferred. The effects of the present invention can be achieved by incorporating one or more of these in the drug carrier.

[0015] The bag body using the anti-mite agent can be a single layer of folded fabric, or a structure in which multiple layers of fabric or cloth are layered. The front and back sides of the bag body when folded can have different layer structures. For example, in the case of preparing an anti-mite bag body that also functions as a pillow cover for wrapping a pillow, the bag body located on the front side of the pillow can be used with a natural anti-mite agent or a ceramic anti-mite agent, assuming that it is close to the human body, and an organic anti-mite agent can be used on the back side of the pillow. In this case, the bag body can be colored according to the components of the anti-mite agent to distinguish them. For example, the structural part containing the natural anti-mite agent can be colored green, the structural part containing the ceramic anti-mite agent can be colored blue, and the structural part containing the organic anti-mite agent can be colored red. In addition, the bag body can be made reversible with a two-layer structure as a whole. For example, a ceramic anti-mite agent can be used on the inside and a natural anti-mite agent on the outside, and a user who feels that it is not preferable for the plant-derived anti-mite agent to be close to the human body can use the bag by inverting the inside and outside. In addition to the layer containing the anti-mite component, a fabric that is highly moisture permeable and can block the passage of nuisance pests can also be added, and the use of such a fabric can further enhance the anti-mite effect.

[0016] The anti-mite bag of the present invention can also be provided with an antibacterial and deodorizing effect. There are several methods for providing the antibacterial and deodorizing effect to the anti-mite bag, one of which is to mix an antibacterial and deodorizing agent such as a silver ion type with the anti-mite agent, and another method is to fix an antibacterial and deodorizing agent such as a silver ion type on the surface of the main sheet material with anti-mite effect by spraying or coating. It is also possible to give the anti-mite bag of the present invention a multi-layer structure and provide an antibacterial and deodorizing functional layer in a layer separate from the anti-mite functional layer.

[0017] The shape of the bag body according to the present invention is not particularly limited as long as it is a shape that allows the stored object to be stored in the bag, and may be a shape in which a sheet having four corners is folded in the center, two sides are sewn or glued together, and one side is made into an opening. The bag body may also be a bag body in which a cylindrical body is cut and the opening of the cut part is closed. The size of the bag body according to the present disclosure may also vary depending on the stored object.

[0018] Items to be stored in the anti-mite bag of the present invention include bedding such as mattresses, pillows, futons, and comforters, furniture or interior items such as cushions, sofas, cushions, long cushions, chair seats and backs, and handrails, and clothing items such as suit covers and kimono covers.Furthermore, they can function not only for humans, but also as a measure against unpleasant pests for non-human organisms such as animals and birds.

[0020] Hereinafter, an embodiment will be described with reference to the drawings. The anti-mite bag described first is a anti-mite bag that functions as a pillow cover, as shown in Figs. 1 to 3.

[0021] As shown in Figures 1 to 3, the pillow cover 10 of this embodiment has an opening 14 in the bag body 12 through which the pillow 20 to be stored can be inserted, and is larger than the size of the pillow 20 to be stored (single: 43 cm x 64 cm), for example, 45 x 78 cm. The opening 14 is formed at one end of the bag body 12, and when the pillow 20 is fully pushed inside the bag body 12, a part of the bag body 12 is left over near the opening 14 due to the large size of the bag body 12, and can be folded, and the folded part functions as a closing part 16. A hook-and-loop fastener, a fastener, an adhesive tape, etc. can also be arranged in the closing part 16.

[0022] The pillow cover 10 of this embodiment can be used as it is by placing it against the head as a pillow cover, or the pillow cover 10 of this embodiment can be used as an inner cover and an outer pillow cover 22 can be placed on the outside of it. Since the inner cover has an anti-dust mite effect, the user can enjoy a comfortable sleep.

[0023] The anti-mite effect is achieved by a ceramic anti-mite agent contained in the main sheet material 11 of the bag body 12. The ceramic anti-mite agent is an inorganic compound such as boric acid ceramics that release B2O3, or ceramics with copper, silver, platinum or a mixture of these supported on the surface, and is supported on, for example, polyethylene resin to kill and repel unpleasant insects, protecting the pillow 20 inside from unpleasant insects even with long-term use, and protecting the user's body from mites.

[0024] The ceramic-based anti-mite agent used in this embodiment is designed to have a long-lasting effect of about half a year, and the anti-mite effect of ceramics prevents the breeding of unpleasant pests. The inventors of this invention have confirmed this effect by conducting a test in accordance with JIS L-1920. The test was a test of anti-mite performance (growth inhibition test) for textile products according to the JIS standard, and Dermatophagoides pteronyssinus was used as the test mite. A comparison was made between pillow covers made of the anti-mite bag of this invention (Examples A and B) and a normal pillow cover without the anti-mite bag (Comparative Example) in terms of the number of remaining mites. Example A is colored, and Example B is colorless.

[0025] [Table 1]

[0026] As is clear from this table, in the pillow covers made of the anti-mite bags of Examples A and B, the number of mites was significantly reduced to 129 and 147 after 8 weeks compared to 3,375 in the comparative example, indicating that high proliferation inhibition rates of 96.2% and 95.6% were achieved.

[0027] The main sheet material of the anti-mite bag having such a mite reducing effect can be a single layer structure as shown in Fig. 4(a), but may also be a multi-layer structure as shown in Fig. 4(b) or (c). In the case of the single layer structure 40 shown in Fig. 4(a), a polyester synthetic resin or the like is used as a carrier 41, and inorganic compounds such as boric acid ceramics that release B2O3, or ceramics with copper, silver, platinum, or a mixture of these supported on the surface are supported on the carrier. Naturally derived anti-mite agents can be used instead of these ceramics, and similarly, naturally derived anti-mite agents may be supported on the carrier.

[0028] In the case of the multi-layer structure 42 shown in Fig. 4(b), different types of layers can be formed, and as an example, the outer layer 43 can be a layer containing a ceramic-based anti-mite agent, and the inner layer 44 can be a layer containing a naturally derived anti-mite agent. It is also possible to obtain a synergistic effect by using two or more types of anti-mite agents. In addition, the inner layer 44 can be impregnated with an organic anti-mite agent, and since the inner layer 44 is configured not to come into direct contact with the human body during use, it is easy to use even for users with sensitive skin.

[0029] In the case of the multi-layer structure 45 shown in Fig. 4(b), it has a three-layer structure of an outer layer 46, an intermediate layer 47, and an inner layer 48, and for example, either the intermediate layer 47 or the inner layer 48 is used as a base layer made of a material for maintaining the shape of the bag-like main body, and due to the presence of such a base layer, the outer layer 46 can be made to contain an anti-mite agent, while at the same time either the intermediate layer 47 or the inner layer 48 can be made to contain an anti-mite agent. It is desirable that the base layer has fine holes that do not allow unpleasant pests such as mites to pass through, and that the breathability of the anti-mite bag as a whole is guaranteed.

[0030] Such a single-layer or multi-layered anti-mite bag can also be provided with antibacterial and deodorizing effects. For example, when the anti-mite bag of the present invention is a multi-layered structure, it is possible to provide an antibacterial and deodorizing functional layer in a layer separate from the anti-mite functional layer. The inventors of the present invention conducted antibacterial tests of textile products according to JIS L1902 for the anti-mite bag provided with antibacterial and deodorizing effects, and obtained antibacterial activity values ​​of 5.3 and 6.0. Since the standard value is 2.0, it can be seen that high antibacterial performance is also obtained.

[0031] Furthermore, in order to impart antibacterial and deodorizing effects to such anti-mite bags, antibacterial and deodorizing agents such as silver ions can be added by mixing or spraying them. For example, a method is possible in which an antibacterial and deodorizing agent such as a silver ion is mixed into the anti-mite agent. Another method is to fix an antibacterial and deodorizing agent such as a silver ion type to the surface of the main sheet material that already has anti-mite effects by spraying or applying it.

[0032] As another embodiment of the anti-mite bag, an example in which different types of anti-mite agents are used on the front and back is shown in Fig. 5. The anti-mite bag 50 shown in Fig. 5 has an opening 51 through which a pillow or other stored item can be inserted, the front surface 52 has a two-layer structure of an outer layer 56 and an inner layer 58, and the back surface 54 has a single layer structure of the outer layer 56. For example, if the outer layer 56 of the anti-mite bag 50 is a layer containing a ceramic-based anti-mite agent and the inner layer 58 is a layer containing a naturally derived anti-mite agent, it is possible to place an anti-mite agent made of essential oils derived from cypress, which has a high sleep-inducing effect, only on the surface closest to the user, thereby providing a more excellent anti-mite effect.

[0033] Figures 6 to 8 each show an example of changing the object contained in the anti-mite bag. Figure 6 shows an example of furniture, an anti-mite bag 64 covering a cushion 62 of a sofa 60, Figure 7 shows an example of the anti-mite bag being used as a suit cover 70, and Figure 8 shows an example of the anti-mite bag being a cushion cover 80.

[0034] 6, a pair of cushions 62 arranged on the seat surface of a sofa 60 are typically shown stored in a cushion cover 64 according to the embodiment, and an anti-mite agent is carried on the main sheet material of the cushion cover 64. In this way, the main bag body of the anti-mite bag according to the present invention can store a cushioning material or a part of a piece of furniture, and can be applied to furniture other than sofas, such as chairs.

[0035] In the example shown in Fig. 7, the anti-mite bag is used as a suit cover 70, a hanger 72 is arranged inside, and a suit 74 is stored so as to be wrapped in the suit cover 70. The suit cover 70 is shaped like a suit jacket, but an opening 76 is provided vertically on one side, and a fastener 78 is also attached to allow the opening 76 to be opened and closed. The anti-mite bag of the present invention can be applied to such a suit cover 70, and can also be used as an athletic clothing cover, a Japanese clothing cover, a hat cover, a shoe cover, a handkerchief cover, a sock cover, an underwear cover, and the like, in addition to the suit cover 70.

[0036] In the example shown in Fig. 8, the anti-mite bag is a cushion cover 80, inside which a cushion 82 can be accommodated. The cushion can be changed in size to suit long cushions, etc. Also, while pillow covers have been described as bedding, it goes without saying that the anti-mite bag of the present invention can be applied to other bedding and interior items such as quilt covers, futon covers, blanket covers, towel blanket covers, mattress covers, mat covers, carpet covers, rug covers, slipper covers, and towel covers.

[0037] The anti-mite bag of the present invention does not collect unpleasant pests like disposable devices, but exerts a relatively long-term anti-mite effect as long as the effect of the anti-mite agent carried in the main body continues. Therefore, the stored items can be used cleanly and safely without being invaded by unpleasant pests such as mites. In addition, anti-mite agents derived from natural origin can also have a psychological effect on restful sleep, providing a comfortable feeling to the user, especially when used for bedding.
