Description

Technology Field

[0001] The present invention relates to a flying insect repellent product comprising a silicone rubber serving as a base material and a molded body containing a flying insect repellent component, and a flying insect repellent method using the same. Background Technology

[0002] Conventionally, as a product for repelling flying insects such as mosquitoes, robber flies, midges, and flies, a product for repelling flying insects has been proposed in which a liquid composition containing a flying insect repellent component, such as an essential oil, is incorporated into a silicone rubber molded body (see, for example, Patent Documents 1 and 2). These flying insect repellent products utilize the properties of silicone rubber, which has excellent adsorption and gas permeability and is also physically stable, and are processed into rings, wristbands, etc., and are used by being attached to the wrist of the human body. Prior art literature

[0003] International Publication No. 2013 / 187463 and Japanese Patent Publication No. 2018-095697 The problem to be solved

[0004] In emergency insect repellent products such as those described in Patent Documents 1 and 2, in order to increase the repellent effect, it is necessary to increase the amount of emergency insect repellent components contained in the silicone rubber molded body. To achieve this, it was necessary to increase the mass of the silicone rubber molded body, that is, to make the silicone rubber molded body thicker (increase the cross-sectional area). However, as the silicone rubber molded body becomes thicker, elasticity decreases, and there is a risk that the fitability may decrease, such as when attaching it to the wrist, for example, it becomes difficult to pass through a fist.

[0005] Meanwhile, if the silicone rubber molded body is made thinner to prioritize ease of installation, as described above, the amount of emergency pest repellent component contained in the silicone rubber molded body is reduced, and there is a risk that the repellent effect will be lowered.

[0006] As such, in an emergency insect repellent product made by incorporating an emergency insect repellent component into a silicone rubber molded body, the repellent effect and the attachability are in a trade-off relationship, and it is difficult to increase these two conflicting effects simultaneously.

[0007] The present invention is made in consideration of the above circumstances and aims to provide an emergency pest repellent product capable of simultaneously enhancing mutually contradictory effects, namely repellent effect and attachability, and an emergency pest repellent method using the same. means of solving the problem

[0008] In order to solve the above problem, the inventors have conducted diligent research and have found the following. Specifically, in an emergency insect repellent product, a silicone rubber molded body is molded into a belt-like body or a ring body for attachment to the wrist or the like. For silicone rubber molded bodies having the same composition and characteristics, if the type of emergency insect repellent component contained therein is the same, the amount of emergency insect repellent component that can be contained in the silicone rubber molded body (the amount that can be contained therein) depends on the mass of the silicone rubber molded body. Therefore, to increase the repellent effect, the mass of the silicone rubber molded body can be increased. In addition, since the above-mentioned content is determined by the composition and characteristics of the silicone rubber molded body and the type of emergency insect repellent component, in any combination of the composition and characteristics of the silicone rubber molded body and the type of emergency insect repellent component, if the mass of the silicone rubber molded body is increased, it becomes possible to include as much of the emergency insect repellent component as possible in the silicone rubber molded body according to the content of each combination.

[0009] Here, for example, as in the above-mentioned Patent Document 1, when a silicone rubber molded body is formed with a uniform line diameter (thickness) along the entire longitudinal axis of a strip or annular body, in order to increase the mass of the silicone rubber molded body, it is necessary to make the silicone rubber molded body uniformly thick, and as a result, there is a risk that elasticity will decrease and fitability will decrease. Conversely, if the silicone rubber is made uniformly thin, elasticity will increase and fitability will improve, but there is a risk that the mass of the silicone rubber molded body will decrease and the repellent effect will decrease. On the other hand, for example, if only a part along the longitudinal axis is formed to be locally thick, it is necessary to realize an increase in the mass of the entire silicone rubber molded body by increasing the mass of that part, so it is necessary to make it extremely thicker than other parts or to expand the area occupied by the thick part along the longitudinal axis, and as a result, there is a risk that the elasticity of the entire silicone rubber molded body will decrease.

[0010] In this regard, the inventors have discovered that by adopting the following configuration, it is possible to enhance both of the opposing effects of repellency and fitability, and have completed the present invention.

[0011] That is, the characteristic configuration of the emergency pest repellent product related to the present invention for solving the above problem is,

[0012] An emergency insect repellent product comprising a silicone rubber base and a molded body containing an emergency insect repellent component,

[0013] The above-mentioned molded body is a strip-shaped or annular body having a plurality of first elements (E1) and a plurality of second elements (E2) (the first elements (E1) and the second elements (E2) have different configurations),

[0014] The first element (E1) and the second element (E2) are alternately arranged along the longitudinal axis of the strip shape or the annular shape.

[0015] In a silicone rubber molded body, if a first element (E1) and a second element (E2) having different configurations, for example, different thicknesses and different inclinations (different shapes) with respect to the longitudinal axis are alternately arranged along the longitudinal axis, each adjacent first element (E1) and second element (E2) has a different configuration and can perform different functions according to each configuration.

[0016] According to the emergency insect repellent product of the present configuration, if the adjacent first element (E1) and second element (E2) are taken as one unit, the unit performs two different functions corresponding to each element. By arranging the unit continuously along the longitudinal axis, the first element (E1) and second element (E2) can be arranged alternately, and the emergency insect repellent product as a whole performs two functions. Furthermore, one of the first element (E1) and second element (E2) can be primarily configured to function as a volatilization part that volatilizes the emergency insect repellent component maintained in the gaps of the molecular structure of the silicone rubber in the silicone rubber molded body, and the other can be primarily configured to function as an elongation part that extends the size of the silicone rubber molded body along the longitudinal axis. Accordingly, by having the first element (E1) and the second element (E2) alternately arranged along the longitudinal axis, it becomes possible to simultaneously enhance the opposite effects of repulsion and fit.

[0017] In the emergency pest repellent product of the present invention,

[0018] It is preferable that the cross-sectional area S1 in the direction perpendicular to the longitudinal axis of the first element (E1) is configured to be larger than the cross-sectional area S2 in the direction perpendicular to the longitudinal axis of the second element (E2).

[0019] According to the emergency pest repellent product of the present configuration, by setting the cross-sectional area S1 of the first element (E1) to be larger than the cross-sectional area S2 of the second element (E2), the relatively thick first element (E1) can be made to function as the aforementioned vaporizing part and the relatively thin second element (E2) can be made to function as the aforementioned elongating part simply by changing the shape. Therefore, it becomes possible to simultaneously enhance the mutually opposite effects of repellent effect and attachability with a simpler configuration.

[0020] In the emergency pest repellent product of the present invention,

[0021] When viewed from the side, it is preferable that at least one of the first element (E1) and the second element (E2) is configured to intersect obliquely with respect to the longitudinal axis.

[0022] According to the emergency insect repellent product of the present configuration, by configuring at least one of the first element (E1) and the second element (E2) to intersect obliquely with respect to the longitudinal axis, the boundary between the first element (E1) and the second element (E2) is also configured to intersect obliquely. As a result, when the product is pulled along the longitudinal axis when mounted on a wrist or the like, stress concentration at the boundary can be relieved, thereby suppressing the breakage of the emergency insect repellent product. In addition, when the emergency insect repellent product is mounted on a wrist or the like, normally, the product is pulled obliquely along the wrist or the like, and at this time, the emergency insect repellent product becomes easier to roll around the longitudinal axis, making it easier to mount.

[0023] In the emergency pest repellent product of the present invention,

[0024] It is preferable that when the above-mentioned molded body is mounted on a person's wrist or arm, the drag stress measured when the molded body is grasped and pulled forward while moving sideways is 7.5 N / 5 mm or less per unit width (5 mm).

[0025] According to the emergency insect repellent product of the present configuration, by setting the drag stress to the above range, the emergency insect repellent product becomes easy to move (slip, roll, etc.) on the surface to which it is mounted with relatively little force, thus making it easy to mount.

[0026] In the emergency pest repellent product of the present invention,

[0027] The first element (E1) above primarily functions as a volatilizing part that volatilizes the emergency pest repellent component maintained in the gaps of the molecular structure of the silicone rubber, and

[0028] It is preferable that the second element (E2) above primarily functions as an elongation part that increases the size of the molded body in the longitudinal direction.

[0029] According to the emergency pest repellent product of the present configuration, by dividing the functions between the first element (E1) and the second element (E2) in this way, it becomes possible to more effectively simultaneously enhance the opposing effects of repellency and attachment.

[0030] A characteristic configuration of an emergency pest repellent method related to the present invention for solving the above problem is,

[0031] As an emergency pest repellent method using the above-mentioned emergency pest repellent product,

[0032] The above-mentioned emergency insect repellent product is attached to the human body to vaporize the emergency insect repellent component around the human body, thereby repelling emergency insects.

[0033] As described above, since the emergency insect repellent product simultaneously enhances the mutually contradictory effects of repellency and ease of attachment, it is unlikely that there will be reasons hindering attachment, such as difficulty in attachment or failure to obtain a repellency effect. Furthermore, after attachment, it can exhibit a higher repellency effect than conventional products. Therefore, according to the emergency insect repellent method of the present configuration, the repellency effect can be enhanced compared to the case where conventional emergency insect repellent products are used, due to the high ease of attachment and repellency of the emergency insect repellent product.

[0035] Hereinafter, the emergency pest repellent product and the emergency pest repellent method of the present invention will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

[0036] [Emergency Pest Repellent]

[0037] FIG. 1 is a schematic perspective view showing an emergency pest repellent product according to one embodiment of the present invention. FIG. 2 is a schematic perspective view showing a cut-out and enlarged portion (3 units) of the emergency pest repellent product of FIG. 1. The emergency pest repellent product (100) of the present embodiment is composed of a molded body (10) based on silicone rubber. The silicone rubber contains an emergency pest repellent component. In addition to the emergency pest repellent component, the molded body (10) may contain other components as described below.

[0038] (Silicone rubber)

[0039] The silicone rubber used as the substrate for the molded body (10) (emergency insect repellent product (100)) has excellent gas permeability, is also stable in terms of physical properties, and has excellent adsorption and emission of emergency insect repellent components. This is thought to be because the molecular structure of the emergency insect repellent component consists of a main chain composed of carbon, and the molecules of the emergency insect repellent component are easily able to enter the gaps in the molecular structure of the silicone rubber, which is cross-linked in three dimensions.

[0040] In order to utilize the properties of silicone rubber, it is desirable to set the hardness (Shore A hardness, HA) of the silicone rubber molded body to 20 to 50 degrees, and more desirable to set it to 30 to 40 degrees. The hardness of the silicone rubber molded body can be adjusted by increasing or decreasing the amount of crosslinking agent (vulcanizing agent or additive) blended with the silicone rubber raw material, or by changing the curing temperature (crosslinking temperature). If the hardness of the silicone rubber molded body does not meet the above range, there is a risk that the elasticity will be weak and the recovery (rebound) of the silicone rubber molded body will be reduced. On the other hand, if the hardness of the silicone rubber molded body exceeds the above range, there is a risk that the durability will be reduced. In this regard, by setting the hardness of the silicone rubber molded body to the above range, it is possible to have appropriate elongation and sufficient durability. Furthermore, the hardness of the silicone rubber molded body is measured by a method or apparatus in accordance with the Japanese Industrial Standard (JIS K6253). In this embodiment, the hardness of the silicone rubber molded body is measured as Shore A hardness (HA) using a durometer (Type A) suitable for the above standard.

[0041] Silicone rubber can be used regardless of whether it is a room temperature curing type, a heat curing type, a condensation type, or an addition type. Typically, a vulcanizing agent, a reaction aid, and additives are mixed into a raw material, such as a silicone compound or a liquid silicone polymer, and then vulcanized (crosslinked) by heating and pressurizing, and then molded. Specifically, for example, after adding a vulcanizing agent to a silicone compound, the mixture is poured into two molds divided into two parts to form a shape as shown in Fig. 1, for example, and then combined by joining them together and then releasing the molds to obtain a silicone molded body as an integral molded body. Furthermore, by adjusting the crosslinking density of the silicone rubber or adjusting the amount of silicone oil or filler used as an additive, the amount of volatilization of the insect repellent component added later can be controlled.

[0042] The silicone rubber used in this embodiment may contain other types of rubber. For example, if fluororubber is included in addition to silicone rubber, improved durability is expected.

[0043] The silicone rubber molded body is configured as an annular body having a retractable ring portion into which a human wrist, etc. is inserted or mounted, or as a strip-shaped body that becomes an annular body by connecting both ends. When the silicone rubber molded body and the molded body (10) containing an emergency insect repellent component maintained in the silicone rubber molded body are mounted on the wrist, etc., the emergency insect repellent component gradually volatilizes from the surface of the molded body (10). For example, in the case of an emergency insect repellent product (100) in which the volatilization state lasts for 5 to 15 hours, in order to maintain such volatilization performance, it is preferable that the average volatilization amount of the emergency insect repellent component is 0.05 to 1.0 mg / ㎠·h per total surface area of ​​the molded body (10). By setting the average volatilization amount of the emergency insect repellent component to the above range, the bleed of the emergency insect repellent component within the molded body (10) proceeds stably and smoothly for 5 to 15 hours, preferably 8 to 12 hours, while suppressing stickiness. If the average volatilization amount of the emergency insect repellent component is less than 0.05 mg / ㎠·h, the emergency insect repellent effect is insufficient, and if the average volatilization amount of the emergency insect repellent component exceeds 1.0 mg / ㎠·h, there is a concern that the duration of the repellent effect will be shortened, and furthermore, the possibility of causing stickiness on the surface due to an excessive amount of retention in the molded body of the emergency insect repellent component or the emergency insect repellent composition containing it cannot be avoided. In addition, in this embodiment, the average volatilization amount is defined as calculating the average value over a time period in which a volatilization amount of 0.02 mg / ㎠·h or more is observed. Also, since the shape of the silicone rubber molded body is identical to the shape of the emergency insect repellent product (100) (molded body (10)), it will be described later with the shape of the emergency insect repellent product (100).

Furthermore, as long as it does not impair the effect of the present embodiment, it may appropriately include functional components, solvents, surfactants, solubilizing agents, dispersants, stabilizers, pH adjusters, coloring agents, etc., as needed. In these cases, the emergency insect repellent component is prepared as an emergency insect repellent composition together with other components and is maintained in a silicone rubber molded body. Additionally, it is possible to stabilize the emergency insect repellent composition or control the volatility of the emergency insect repellent component by, for example, microencapsulating or cyclodextrinizing the emergency insect repellent composition.

[0063] Absorption-promoting ingredients

[0064] The absorption-promoting component is a component that promotes the absorption of an emergency insect repellent component into a silicone rubber molded article. As the absorption-promoting component, d-limonene and / or 1,8-cineole are preferred. The content of the absorption-promoting component in the emergency insect repellent composition is preferably 2.0 to 65 mass%, and more preferably 10 to 45 mass%.

[0065] <Ingredients for sustained repellent effect>

[0066] The repellent effect sustaining component is a component that sustains the repellent effect upon volatilization of the emergency pest repellent component. As a repellent effect sustaining component, it is preferable to further contain glycol and / or glycol ether having a vapor pressure of 0.2 to 20 Pa at 20°C. Specific examples of glycol and / or glycol ether (vapor pressure at 20°C also specified) include propylene glycol (10.7 Pa), dipropylene glycol (1.3 Pa), tripropylene glycol (0.67 Pa), diethylene glycol (3 Pa), triethylene glycol (1 Pa), 1,3-butylene glycol (8 Pa), hexylene glycol (6.7 Pa), benzyl glycol (2.7 Pa), diethylene glycol monobutyl ether (3 Pa), dipropylene glycol monobutyl ether (6 Pa), and tripropylene glycol monomethyl ether (1.7 Pa), among which dipropylene glycol is preferred.

[0073] <Content of emergency insect repellent ingredient or emergency insect repellent composition in emergency insect repellent products>

[0074] The content (maintenance amount) of the emergency insect repellent component or emergency insect repellent composition in the emergency insect repellent product (100) can be appropriately set according to the intended use and duration of use of the emergency insect repellent product (100), and the type or specifications of the molded body (10). For example, in the case of an emergency insect repellent product (100) used for 8 to 12 hours per use, it is suitable to maintain the emergency insect repellent component in the range of 20 to 500 mg per molded body (10). In the case of an emergency insect repellent product (100) used for 15 to 30 days, it is preferable to incorporate about 100 to 2000 mg of the emergency insect repellent component per molded body (10).

[0075] <Retention of emergency pest repellent components in silicone rubber molded bodies>

[0076] An emergency insect repellent product (100) is obtained as a molded body (10) by adding an emergency insect repellent component or an emergency insect repellent composition containing an emergency insect repellent component to a silicone rubber molded body and performing a predetermined treatment to infuse it into the silicone rubber molded body (e.g., retaining or impregnating). As a method for infusing the emergency insect repellent component or the emergency insect repellent composition into the silicone rubber molded body, conventionally known methods may be appropriately employed. For example, if the surface area of ​​the silicone rubber molded body is large, the emergency insect repellent component or the emergency insect repellent composition is infused by a liquid dispensing method or a coating method. If the surface area of ​​the silicone rubber molded body is small, a plurality of silicone rubber molded bodies are placed in a sealed container, and the emergency insect repellent component or the emergency insect repellent composition is added to it along with a solvent as needed, sprayed or dripped, and infiltrated into the silicone rubber molded body. In addition, it is also possible to obtain an emergency insect repellent product (100) which is a molded body (10) containing an emergency insect repellent component or an emergency insect repellent composition by means of a method such as immersing a silicone rubber molded body in a liquid of an emergency insect repellent component or an emergency insect repellent composition for a suitable period of time, or mixing a silicone rubber molded body containing an emergency insect repellent component or an emergency insect repellent composition at a high concentration with an untreated silicone rubber molded body in a sealed container and leaving it for a suitable period of time to average the concentration of the emergency insect repellent component or the emergency insect repellent composition throughout the silicone rubber molded body.

[0077] (Shape and specifications of emergency pest repellent products)

[0078] The shape and specifications of the emergency insect repellent product (100) are described. The shape of the emergency insect repellent product (100) is identical to the shape of the silicone rubber molded body described above. Therefore, the shape of the emergency insect repellent product (100) described below corresponds to the description of the shape of the silicone rubber molded body.

[0079] As shown in FIGS. 1 and 2, the emergency pest repellent product (100) (molded body (10)) of the present embodiment is a strip-shaped or annular body having a plurality of first elements (E1) and a plurality of second elements (E2). The first elements (E1) and the second elements (E2) have different configurations from each other. The first elements (E1) and the second elements (E2) are alternately arranged along the longitudinal axis (R) of the strip-shaped or annular body (annular body in FIG. 1). In the embodiment shown in FIGS. 1 and 2, the first elements (E1) and the second elements (E2) have different shapes, and specifically, the first element (E1) is formed thicker than the second element (E2). Additionally, the first element (E1) is formed obliquely in the direction of one longitudinal axis (R) (clockwise direction in FIG. 1) in each of the upward and downward directions from one side to the other side, and is formed as a convex portion so as to be connected (joined) on the other side. The concave portion between the two consecutive first elements (E1) is formed as a second element (E2).

[0080] In a silicone rubber molded body, if a first element (E1) and a second element (E2) having different configurations, for example, different thicknesses and different inclinations (different shapes) with respect to the longitudinal axis (R), are alternately arranged along the longitudinal axis (R), then each adjacent first element (E1) and second element (E2) have different configurations and can perform different functions according to each configuration. According to the emergency pest repellent product (100), if the adjacent first element (E1) and second element (E2) are taken as one unit, the unit performs two different functions corresponding to each element. By arranging the unit continuously along the longitudinal axis (R), the first element (E1) and second element (E2) can be alternately arranged, and the emergency pest repellent product (100) as a whole performs two functions. In addition, one of these first element (E1) and second element (E2) (here, the first element (E1)) can be primarily functioned as a volatilization part that volatilizes the parasitic insect repellent component maintained in the gaps of the molecular structure of the silicone rubber in the silicone rubber molded body, and the other part (here, the second element (E2)) can be primarily functioned as an elongation part that extends the size along the longitudinal axis (R) of the silicone rubber molded body. Accordingly, by arranging the first element (E1) and the second element (E2) alternately along the longitudinal axis (R), it becomes possible to simultaneously enhance mutually opposing effects such as repellency and fitability. In addition, as shown in FIGS. 1 and 2, in this embodiment, the first element (E1) and the second element (E2) are alternately and regularly arranged along the longitudinal axis (R). In this case, since the evaporation and elongation parts can be arranged more evenly than the whole, it is possible to further enhance the avoidance effect and mounting ability.

[0081] In the emergency insect repellent product (100), it is preferable that the first element (E1) primarily functions as a volatilizing part that volatilizes the emergency insect repellent component maintained in the gaps of the silicone rubber molecular structure, and the second element (E2) primarily functions as an elongating part that extends the lengthwise size of the molded body (10). By dividing the functions between the first element (E1) and the second element (E2) in this way, it becomes possible to more effectively enhance the opposite effects of repellent effect and fitability simultaneously. However, the first element (E1) may also function as an elongating part that extends the lengthwise size of the molded body (10), and the second element (E2) may also function as an eolatilizing part that volatilizes the emergency insect repellent component maintained in the gaps of the silicone rubber molecular structure.

[0082] In the emergency pest repellent product (100), as shown in FIGS. 1 and 2, it is preferable that the cross-sectional area S1 in the direction perpendicular to the longitudinal axis (R) of the first element (E1) be larger than the cross-sectional area S2 in the direction perpendicular to the longitudinal axis (R) of the second element (E2). By setting the cross-sectional area S1 of the first element (E1) to be larger than the cross-sectional area S2 of the second element (E2), the relatively thick first element (E1) can be made to function as the aforementioned vaporizing part and the relatively thin second element (E2) can be made to function as the aforementioned elongating part simply by changing the shape. Therefore, it becomes possible to simultaneously enhance the opposite effects of repellent effect and attachability with a simpler configuration.

[0083] In the emergency insect repellent product (100), when viewed from the side (in the direction of the white arrow in FIG. 1, i.e., as seen in FIG. 2), it is preferable that at least one of the first element (E1) and the second element (E2) be configured to intersect obliquely with respect to the longitudinal axis (R). By configuring at least one of the first element (E1) and the second element (E2) to intersect obliquely with respect to the longitudinal axis (R), the boundary between the first element (E1) and the second element (E2) is also configured to intersect obliquely. As a result, when the product is pulled along the longitudinal axis (R) while mounted on a wrist or the like, stress concentration at the boundary can be relieved, and the breakage of the emergency insect repellent product (100) can be suppressed. In addition, when attaching the emergency insect repellent product (100) to the wrist, etc., the emergency insect repellent product (100) is pulled diagonally along the wrist, etc., so that the emergency insect repellent product (100) can roll around the longitudinal axis (R), making it easier to attach.

[0084] In the case of the emergency insect repellent product (100), when the molded body (10) is attached to a person's wrist or arm, it is preferable that the drag stress measured when the molded body (10) is grasped and pulled forward while moving sideways is 7.5 N / 5 mm or less per unit width (5 mm), more preferable that it is 6 N / 5 mm or less, and even more preferable that it is 4 N / 5 mm or less. By setting the drag stress to the above range, the emergency insect repellent product (100) becomes easier to move (slip, roll, etc.) on the surface to which it is attached with relatively little force, thus making it easier to attach. Furthermore, the method for measuring the drag stress will be explained in the embodiments described later. "Forward" means the direction approaching the wearer, and may be a direction facing the wearer upward, a direction facing the wearer downward, or a direction facing the wearer horizontally.

[0085] The cross-sectional shape of the emergency pest repellent product (100) is not particularly limited and can be appropriately set. For example, the cross-sectional shape of the emergency pest repellent product (100) can be represented as the shape of the outer edge of a projection view projected along the longitudinal axis (R) by cutting the molded body (10) perpendicularly to the longitudinal axis (R). Examples of the shape of the outer edge of the projection view include polygonal shapes such as circular shapes, elliptical shapes, and square shapes, or shapes with rounded angles of these polygonal shapes. Among these, a roughly circular shape including circular shapes and elliptical shapes is preferred.

[0086] The thickness (thickness) t of the emergency insect repellent product (100) is preferably 1.5 to 8 mm, and more preferably 2 to 5 mm. By setting the thickness t to the above range, it becomes easy to attach to the wrist, etc. Thickness t refers to the maximum thickness.

[0087] The width (width) w of the emergency insect repellent product (100) is preferably 1.5 to 8 mm, and more preferably 2 to 5 mm. By setting the width w to the above range, it becomes easy to attach to the wrist, etc. Width w refers to the maximum width.

[0088] The ratio of thickness t to width w (t / w) is preferably 0.3 to 3, more preferably 0.4 to 2, and even more preferably 0.8 to 1.2. By setting the ratio (t / w) to the above range, when mounted on the wrist, etc., the emergency insect repellent product (100) becomes easy to roll on the surface of the wrist, etc., making it easy to mount.

[0089] The mass of the emergency insect repellent product (100) is preferably 1 to 10g, more preferably 2 to 10g, and even more preferably 3 to 6g. If the mass of the emergency insect repellent product (100) does not meet the above range, there is a concern that it may not be possible to maintain a sufficient amount of the emergency insect repellent component. On the other hand, if the mass of the emergency insect repellent product (100) exceeds the above range, there is a concern that it may be difficult to install. In this regard, by setting the mass of the emergency insect repellent product (100) to the above range, the amount of the emergency insect repellent component maintained can be sufficiently large, and it also becomes easy to install.

[0090] It is also desirable to set the mass of the emergency insect repellent product (100) in consideration of its relationship with the width w, and in this case, for example, it can be set as the mass per unit width (5 mm) of the emergency insect repellent product (100). The mass per unit width (5 mm) of the emergency insect repellent product (100) is preferably 2.5 g / 5 mm or more, more preferably 3.0 g / 5 mm or more, while 5.5 g / 5 mm or less is preferable, 4.5 g / 5 mm or less is more preferable, and 3.5 g / 5 mm or less is even more preferable. By setting the mass per unit width (5 mm) of the emergency insect repellent product (100) to the above range, the amount of the emergency insect repellent component retained per unit width (5 mm) can be sufficiently large. In addition, this allows the width w of the emergency insect repellent product (100) to be made relatively small, making it easy to mount.

[0091] The inner circumference (total length of the inner circumference) L of the emergency insect repellent product (100) is preferably 150 to 320 mm, and more preferably 180 to 240 mm. If the inner circumference does not meet the above range, there is a risk that it cannot be attached to the wrist, etc., and there is also a risk that it may excessively compress the wrist, etc. On the other hand, if the inner circumference exceeds the above range, it becomes easy to slip off the wrist, etc. after attachment. In this regard, by setting the inner circumference to the above range, attachment is improved and it becomes difficult to slip off after attachment.

[0092] The diameter of the virtual maximum inscribed circle contacting the emergency insect repellent product (100) from the inside is preferably 50 to 80 mm, and more preferably 60 to 70 mm. If the virtual maximum inscribed circle does not meet the above range, there is a risk that it cannot be attached to the wrist, etc., and there is also a risk that it may excessively compress the wrist, etc. On the other hand, if the virtual maximum inscribed circle exceeds the above range, it becomes easy to slip off the wrist, etc. after attachment. In this regard, by setting the virtual maximum inscribed circle to the above range, attachment is improved and it becomes difficult to slip off after attachment.

[0093] The elongation rate S when the emergency insect repellent product (100) is pulled with 30 N is preferably 2.5 to 5.0, and more preferably 3.0 to 4.0. If the elongation rate S does not meet the above range, there is a concern that it cannot be attached to the wrist, etc. On the other hand, if the elongation rate S exceeds the above range, it becomes easy to slip off the wrist, etc. after attachment. The elongation rate S is obtained by using a tensile testing machine to measure the length G0 of the emergency insect repellent product (100) before applying a load and the length G1 (i.e., maximum length) when the emergency insect repellent product (100) is pulled with 30 N in the direction where it is easiest to lengthen the most, and by calculating the ratio of length G1 to length G0 according to the following formula (1).

[0094] Elongation rate S = G1 / G0 … (1)

[0095] The degree to which the emergency insect repellent product (100) is elongated can be set so that it is less likely to be caught by a fist when attached to the wrist, etc. In this regard, it is also desirable to set it by considering the relationship with the inner circumference L (mm) of the emergency insect repellent product (100). For example, if the inner circumference L of the emergency insect repellent product (100) is relatively large, the elongation rate S of the emergency insect repellent product (100) can be set relatively small, whereas if the inner circumference L of the emergency insect repellent product (100) is relatively small, it is necessary to set the elongation rate S of the emergency insect repellent product (100) relatively large. Considering this perspective, by setting the product P of the inner circumference L and the elongation rate S of the emergency insect repellent product (100) to a predetermined range, it becomes possible to set the degree to which the emergency insect repellent product (100) is elongated more appropriately. The product P of the inner circumference L and the elongation rate S is preferably 400 to 1000, more preferably 500 to 900, and even more preferably 600 to 800. By setting the product P to the above range, it becomes easier to mount.

[0096] As described above, the molded body (10) itself can be an emergency insect repellent product (100). Examples of the emergency insect repellent product (100) include bracelets, wristbands, anklets, etc. Additionally, as shown in FIG. 1, a flat portion may be formed in a part of the molded body (10) in which neither the first element (E1) nor the second element (E2) is disposed.

[0097] The emergency pest repellent product (100) obtained in this way is used by attaching 1 to 5 pieces as needed to specific parts such as wrists or ankles in indoor spaces such as entrances, kitchens, bathrooms, living rooms, and bedrooms, or in warehouses and vehicles, or in yards and outdoors. This provides an excellent emergency pest repellent effect over a specified period against emergency pests such as red house mosquitoes, house mosquitoes, and Aedes albopictus, as well as robber flies, midges, flies, small flies (fruit flies, flea flies, etc.), moth flies, and clothes moths. Furthermore, if the emergency pest repellent product (100) does not contain insecticidal components, it can be used without resistance even by people who do not prefer using insecticides, so its practicality is extremely high.

[0098] [Emergency Pest Repellent Methods]

[0099] The emergency pest repellent method of the present embodiment is an emergency pest repellent method using the emergency pest repellent product (100) of the present embodiment described above, and is a method of repelling emergency pests by volatilizing an emergency pest repellent component around the human body by attaching the emergency pest repellent product (100) to the human body.

[0100] As described above, the emergency insect repellent product (100) of the present embodiment has both the repellent effect and the attachability effect enhanced, so it is difficult to attach and there is no reason to hinder attachment such as not obtaining a repellent effect. Therefore, according to the emergency insect repellent method of the present embodiment, the repellent effect can be enhanced compared to the case where a conventional emergency insect repellent product is attached to the human body.

[0101] [Other embodiments]

[0102] In FIG. 1 described above, the molded body (10) of the emergency pest repellent product (100) is shown molded into an annular shape, but in addition, the molded body may be formed into a strip shape. If the molded body is in a strip shape, it can be made into an annular shape by joining the two ends together.

[0103] For other examples, as an emergency pest repellent product, a sun as shown in FIG. 4 may be adopted. FIG. 4 is a schematic plan view showing an emergency pest repellent product (110) of another embodiment of the present invention. In the emergency pest repellent product (110) shown in FIG. 4, the first element (E1) is obliquely arranged in a virtual plane including a longitudinal axis (not shown) as if it intersects the longitudinal axis, and the second element (E2) is obliquely arranged toward the side opposite to the first element (E1), and the entire structure is formed with a tip shape (jawed shape, or in other words, a tip shape that is pointed toward the outer and inner sides). When the emergency pest repellent product (110) is mounted on a wrist, etc., it is installed in a state where it is positioned vertically from the wrist, etc. In the emergency insect repellent product (110), the first element (E1) and the second element (E2) have a uniform thickness and a smooth shape without jagged edges, and are designed to have a longer overall length (larger mass) compared to conventional emergency insect repellent products. As a result, the emergency insect repellent product (110) can contain a larger amount of emergency insect repellent components compared to conventional emergency insect repellent products, thereby increasing the repellent effect. Additionally, when the emergency insect repellent product (110) is pulled while being attached to the wrist or the like, the boundary (curved part) between the first element (E1) and the second element (E2) can be deformed to open, thus increasing elasticity compared to conventional emergency insect repellent products. In this way, in the emergency insect repellent product (110), the first element (E1) and the second element (E2) cooperate to function as a vaporizing part and an elongating part. Other configurations can be set in the same way as the embodiment shown in FIG. 1 described above. In the emergency pest repellent product (110) shown in FIG. 4, the opposite effects of repellent effect and attachability are simultaneously enhanced.

[0104] For other examples, as an emergency pest repellent product, a sun as shown in FIG. 5 may be adopted. FIG. 5 is a schematic plan view showing an emergency pest repellent product (120) of another embodiment of the present invention. In the emergency pest repellent product (120) shown in FIG. 5, the first element (E1) is a part that protrudes outward in a spiral shape around a longitudinal axis (not shown) and functions as a volatilizing part. When viewed from a direction perpendicular to the longitudinal axis, the first element (E1) is formed in multiple places with gaps along the longitudinal axis and is formed continuously as a whole. As a result, compared to conventional emergency pest repellent products, it can contain a large amount of emergency pest repellent components, and the repellent effect is enhanced. The second element (E2) is a concave part between adjacent first elements (E1) and functions as an elongation part. When viewed from a direction perpendicular to the longitudinal axis, the second element (E2) is formed in multiple units with a gap along the longitudinal axis and is formed continuously as a whole. As a result, elasticity is increased compared to conventional emergency insect repellent products. In addition, as with the aforementioned FIG. 1, when viewed from the side, at least one of the first element (E1) and the second element (E2) is configured to intersect obliquely with respect to the longitudinal axis. Meanwhile, the cross-sectional area S1 perpendicular to the longitudinal axis of the first element (E1) is configured to be the same as the cross-sectional area S2 perpendicular to the longitudinal axis of the second element (E2). Other configurations may be the same as the embodiment shown in FIG. 1. In the emergency insect repellent product (120) shown in FIG. 5, both opposing effects, such as repellency and ease of attachment, are enhanced.

[0105] For example, as an emergency pest repellent product, in the case of the sun as shown in FIG. 5, instead of forming the first element (E1) in a spiral shape, it may be formed in an elliptical shape that intersects obliquely with respect to the longitudinal axis (not shown), and this may serve as the functional part. That is, in FIG. 5, the parts hidden on the back side of the first element (E1) are connected to the parts shown on the surface side, and adjacent first elements (E1) may not be continuous, but may be formed with a concave part in between. The second element (E2) is the concave part between adjacent first elements (E1) and functions as an extension part. In this case, the cross-sectional area S1 perpendicular to the longitudinal axis of the first element (E1) is configured to be larger than the cross-sectional area S2 perpendicular to the longitudinal axis of the second element (E2). Other configurations may be the same as the embodiment shown in FIG. 1 above. Even in these emergency pest repellent products, both the repellent effect and the attachability, which are mutually contradictory, are being enhanced.

[0106] For other examples, as an emergency pest repellent product, a sun as shown in FIG. 6 may be adopted. FIG. 6 is a schematic plan view showing an emergency pest repellent product (130) of another embodiment of the present invention. In the emergency pest repellent product (130) shown in FIG. 6 (a), the first element (E1) is a part that protrudes outward in the diameter direction perpendicular to the longitudinal axis (not shown) (i.e., the outer circumference is a part that protrudes outward), and functions as a vaporizing part. When viewed from a direction perpendicular to the longitudinal axis and also perpendicular to the diameter direction, the first element (E1) is formed in multiple places with a gap in the longitudinal axis and is formed continuously as a whole. As a result, compared to conventional emergency pest repellent products, it can contain a large amount of emergency pest repellent components, and the repellent effect is enhanced. The second element (E2) is a concave part between adjacent first elements (E1) and functions as an elongation part. The second element (E2) is formed in multiple units with gaps along the longitudinal axis when viewed from a direction perpendicular to the longitudinal axis and also perpendicular to the diameter direction, and is formed continuously as a whole. As a result, elasticity is increased compared to conventional emergency insect repellent products. The emergency insect repellent product (130) is formed as a whole with an uneven shape (a gear shape with a flat tip) in which the outer side (far from the wrist, etc.) partially protrudes outward. The cross-sectional area S1 perpendicular to the longitudinal axis of the first element (E1) is configured to be larger than the cross-sectional area S2 perpendicular to the longitudinal axis of the second element (E2). In addition, the inner side of the first element (E1) and the second element (E2) is formed flat over the entire circumference. Other configurations may be the same as the embodiment shown in FIG. 1 described above.This emergency pest repellent product (130) is formed in a shape such as a cut-out outer side of an annular molded body (200) having a uniform cross-section perpendicular to the longitudinal axis (i.e., uniform thickness and width), as shown by the dashed line in FIG. 6 (b) (or as shown in FIG. 7). As shown in FIG. 6 (b), the emergency pest repellent product (130) is obtained by virtually dividing the molded body (200) into multiple parts along the longitudinal axis (at equal intervals in FIG. 6 (b)), skipping one virtual part at a time, and forming a shape such as a cut-out from the outer side toward the inner side so that the thickness decreases. This emergency pest repellent product (130) can be formed, for example, by cutting the dashed part from a circular molded body as shown in FIG. 6 (b). Alternatively, it can be formed using a mold cut out into the shape of a molded body as shown in FIG. 6 (a), for example. In the emergency pest repellent product (130) shown in FIG. 6 (a), both of the opposite effects of repellent effect and attachability are enhanced.

[0107] <Example>

[0108] The present invention will be explained in more detail below through examples and comparative examples, but the present invention is not limited to the examples.

[0109] (Example 1)

[0110] After adding a vulcanizing agent, etc. to a silicone compound, the mixture was poured into two molds divided into two parts to form the shape shown in Fig. 1, and then the two parts were combined and released to obtain a silicone molded body. An emergency insect repellent composition (60 mass% as an emergency insect repellent component) was obtained by combining 12 mass% of benzyl acetate, 4 mass% of p-tert-butylcyclohexyl acetate, 7 mass% of allyl heptanoate, 14 mass% of dihydromyrcenol, 8 mass% of geraniol, 15 mass% of other emergency insect repellent components, 24 mass% of d-limonene as an absorption promoter, and 16 mass% of dipropylene glycol as a repellent effect sustaining component. By impregnating a silicone molded body with an emergency insect repellent composition at a rate of 100 mg (60 mg as the emergency insect repellent component) per molded body (3.3 g), an emergency insect repellent product of Example 1 was obtained, which is a string ring type integral molded body having the shape shown in FIG. 1 and the characteristics shown in Table 1. For the emergency insect repellent product of Example 1, hardness (HA), elongation S, and drag stress were measured, and attachment ability and drug impregnation ability were evaluated according to the method. The results are shown in Table 1.

[0111] <Longitude>

[0112] Shore A hardness (HA) was measured using a durometer (Type A) in accordance with the Japanese Industrial Standard (JIS K6253).

[0113] Growth Rate S>

[0114] A tensile testing machine was used to measure the length G0 of the emergency insect repellent product (silicone rubber molded body) before applying a load, and the length G1 (i.e., maximum length) when the emergency insect repellent product (silicone rubber molded body) is pulled with 30N in the direction where it is easiest to lengthen, and the ratio of length G1 to length G0 was calculated according to the following formula (1) to obtain the elongation rate S.

[0115] Elongation rate S = G1 / G0 … (1)

[0116] <Drag Stress>

[0117] FIG. 3 is a schematic diagram showing a method for measuring drag stress of an emergency pest repellent product of an example and a comparative example, FIG. 3 (a) is a diagram showing the state before moving the molded body (10) (i.e., the emergency pest repellent product (100)) to the side (upward in FIG. 3), and FIG. 3 (b) is a diagram showing the state after moving the molded body (10) to the side (upward in FIG. 3). As shown in FIG. 3(a), a drag stress was obtained by installing a mock arm (50) (diameter approximately 6.5 cm) wrapped with artificial skin (Bio Skin Plate P001-001, manufactured by Burax Co., Ltd.) on a base, with the artificial skin (Bio Skin Plate P001-001, manufactured by Burax Co., Ltd.) wrapped around a cylinder with a diameter of 5.3 cm, passing an emergency insect repellent product (100) through the mock arm (50), and attaching the catch portion (61) of the push-pull section (60) of the push-pull tester to the emergency insect repellent product (100) so that the product (100) is parallel to the base and does not slip off. Then, as shown in FIG. 3(b), the catch portion (61) was pulled sideways (upward in FIG. 3) (white arrow in FIG. 3(b)), and the stress obtained when pulled up 12 cm was obtained as the drag stress. By converting the obtained drag stress into stress per unit width (5 mm), the drag stress (N / 5 mm) per unit width (5 mm) was obtained.

[0118] <Fitting Capability>

[0119] The emergency insect repellent product of Example 1 was attached to the wrists of seven panelists, and each panelist scored the fitability at that time as one of 0, 1, 2, or 3 points according to the evaluation criteria below. After calculating the average of the scores from the seven evaluators, the product was evaluated according to the following judgment criteria.

[0120] (metewand)

[0121] 0 points: Almost no snagging during installation, and it was very comfortable to mount (Excellent).

[0122] 1 point: It got stuck halfway, but could be easily mounted with a little force (good).

[0123] 2 points: It got stuck halfway, but could be mounted by applying moderate force (allowed).

[0124] 3 points: If it got stuck midway, it could not be mounted without applying strong force (defective).

[0125] (Judgment Criteria)

[0126] A: 0.3 points or less

[0127] B: Over 0.3 points and under 0.8 points

[0128] C: Over 0.8 points and up to 1.5 points

[0129] D: Over 1.5 points and 2.0 points or less

[0130] E: Exceeds 2.0 points

[0131] Drug impregnation property

[0132] For an emergency insect repellent product (silicone rubber molded body), the greater the mass per unit width (5 mm) calculated from its mass and width, the smaller the contact area with the arm, etc., when the product is attached, the greater the amount of the emergency insect repellent component it can contain. This reduces friction between the product and the arm, etc., thereby improving attachment, and furthermore, it can enhance the repellent effect while reducing exposure of the agent to the skin. Therefore, the mass per unit width (5 mm) of the emergency insect repellent product (silicone rubber molded body) was evaluated according to the following judgment criteria.

[0133] (metewand)

[0134] A. The mass per unit width (5 mm) of the molded body is 3.0 g / 5 mm or more (excellent).

[0135] The mass per unit width (5 mm) of the molded body B is 2.5 g / 5 mm or more and less than 3.0 g / 5 mm (good).

[0136] The mass per unit width (5 mm) of the C molded body is 2.0 g / 5 mm or more and less than 2.5 g / 5 mm (normal).

[0137] The mass per unit width (5 mm) of the D molded body is less than 2.0 g / 5 mm (defective).

[0138] (Example 2)

[0139] Similar to Example 1, a vulcanizing agent was added to a silicone compound, and then poured into two molds divided into two parts to form the shape shown in Fig. 4. The two parts were joined together and then released to obtain a silicone molded body. By impregnating this silicone molded body (4.0 g) with 125 mg (75 mg as an emergency insect repellent component) of the same emergency insect repellent composition as in Example 1, a string ring-shaped emergency insect repellent product of Example 2 was obtained, having the gear shape shown in Fig. 4 and the characteristics shown in Table 1. For the emergency insect repellent product of Example 2, hardness (HA), elongation S, and drag stress were measured in the same manner as in Example 1, and attachment properties and drug impregnation properties were also evaluated. The results are shown in Table 1.

[0140] (Reference Examples 1–12)

[0141] Reference Examples 1 to 12 were prepared by impregnating a silicone rubber molded body having the shape and characteristics shown in Tables 2 to 4 with an emergency insect repellent composition similar to that of Example 1, such that the amount of the emergency insect repellent composition impregnated was 100 mg per 3.3 g of the molded body, similar to Example 1. For these emergency insect repellent products of Reference Examples 1 to 12, in the same manner as in Example 1, hardness (HA) was measured and attachment and drug impregnation properties were evaluated in Reference Examples 1 and 2, and hardness (HA), elongation S, and drag stress were measured and attachment and drug impregnation properties were evaluated in Reference Examples 3 to 12. The results are shown in Tables 2 to 4. In addition, Reference Examples 1 to 12 are formed to have the characteristics of Tables 2 to 4 in the shape of the molded body (300) as shown in FIG. 7. The molded body (300) of FIG. 7 has a rectangular cross-section perpendicular to the longitudinal axis (not shown), and is also formed so that the cross-sectional area is constant over the entire periphery, that is, the thickness and width are constant over the entire periphery.

[0144] [Table 2]

[0145]

[0146] [Table 3]

[0147]

[0148] [Table 4]

[0149]

[0150] The emergency insect repellent products of Examples 1 and 2, in which a plurality of first elements (E1) and a plurality of second elements (E2) are alternately arranged along the longitudinal axis, were rated "A" for both attachment and drug impregnation, and it was shown that both attachment and drug impregnation were excellent. Furthermore, in Example 1, the results of evaluating the elongation S, drag stress, and attachment of the silicone rubber molded body before impregnating it with the emergency insect repellent composition were equivalent to the evaluation results of the elongation S, drag stress, and attachment of the emergency insect repellent product of Example 1 after impregnation shown in Table 1.

[0151] In this regard, the emergency pest repellent products of Reference Examples 1 to 12, in which the first element (E1) and a plurality of second elements (E2) are not arranged, were shown to have at least one of the attachment ability and the drug impregnation ability rated "C" or lower ("C" rating or "D" rating, and "E" rating for attachment ability), and at least one of the attachment ability and the drug impregnation ability was not excellent.

[0152] (Example 3)

[0153] Similar to Example 1, a vulcanizing agent was added to the silicone compound, and then poured into two molds divided into two parts to form the shape of FIG. 6(a). The two parts were joined together and then released to obtain a silicone molded body. By impregnating this silicone molded body (1.6g) with 50mg (30mg as an emergency insect repellent component) of the same emergency insect repellent composition as in Example 1, a string ring-shaped emergency insect repellent product of Example 3 was obtained, having the uneven shape (a gear shape with a flat tip) shown in FIG. 6(a) and the characteristics shown in Table 5. For the emergency insect repellent product of Example 3, hardness (HA), elongation S, and drag stress were measured in the same manner as in Example 1, and attachment properties and drug impregnation properties were also evaluated. The results are shown in Table 5.

[0154] (References 13, 14)

[0155] Reference Examples 13 and 14 were prepared by impregnating a silicone rubber molded body having the shape shown in Fig. 7 and the characteristics shown in Table 5 with an emergency insect repellent composition identical to that of Example 1, such that the impregnation amount of the emergency insect repellent composition was 100 mg per 3.3 g of the molded body, identical to that of Example 1. Reference Example 14 had the same width as Reference Example 13 but a larger thickness. For these emergency insect repellent products of Reference Examples 13 and 14, hardness (HA), elongation S, and drag stress were measured in the same manner as in Example 1, and attachment properties and drug impregnation properties were also evaluated. The results are shown in Table 5.

[0156] [Table 5]

[0157]

[0158] The emergency insect repellent product of Example 3, in which a plurality of first elements (E1) and a plurality of second elements (E2) are alternately arranged along the longitudinal axis, was rated "B" for adhesion and "A" for drug impregnation, and it was shown that both adhesion and drug impregnation were excellent. Furthermore, in Example 3, the results of evaluating the elongation S, drag stress, and adhesion of the silicone rubber molded body before impregnating it with the emergency insect repellent composition were equivalent to the evaluation results of the elongation S, drag stress, and adhesion of the emergency insect repellent product of Example 3 after impregnation shown in Table 5.

[0159] In this regard, Reference Example 13, in which the first element (E1) and a plurality of second elements (E2) are not arranged (i.e., a molded body having the same cross-sectional shape over the entire circumference), was shown to have a “B” rating for adhesion and an “A” rating for drug impregnation, which is equivalent to Example 3, but has a smaller elongation rate S and a larger drag stress than Example 3. In addition, Reference Example 14, which is similar to Example 13 in that the first element (E1) and a plurality of second elements (E2) are not arranged but has a larger thickness than Reference Example 13, was shown to have an “A” rating for drug impregnation but a “D” rating for adhesion, which is inferior to Example 3. In addition, Reference Example 14 was shown to have a larger thickness than Example 3 and a larger ratio of thickness to width, but has a smaller elongation rate S and a larger drag stress than Example 3.
