Description

  The present invention relates to a drug substance, and more particularly to a drug substance wound in a spiral shape.

  BACKGROUND ART Conventionally, incense sticks and the like for controlling a pest such as a mosquito by burning a drug-containing substance containing a drug have been used. In these ordinary incense sticks, the width of the drug-containing body is made substantially constant in order to make the amount of the drug volatilized during combustion constant. Further, in order to prolong the burning time, it is necessary to form the drug-containing substance for a long time. However, in the case of a linear shape, there is a limit to the prolongation of the drug-containing substance, and therefore, it is common to form the drug-containing substance by winding it into a spiral shape. .

  In such a spiral shaped drug-containing body, a complementary set of spiral shapes can be formed by punching and separating a flat drug-containing body into a spiral shape. When the complementary spiral-shaped drug-containing body is separated, a drug-containing body wound to a substantially constant width and a void wound to a substantially constant width are obtained (for example, see Patent Document 1).

  In the above-mentioned conventional drug-containing substance, it can be said that a substantially circular spiral shape is most efficient from the viewpoint of prolonging the burning time and saving space. However, because of the substantially circular shape, the degree of freedom in design is extremely low, and it has been difficult to pursue differentiation in design and appeal to customers with the drug-containing substance itself. On the other hand, there has also been proposed a drug-containing substance that attempts to express a design (for example, see Patent Document 2). However, in Patent Literature 2, a predetermined design is printed with ink or the like in a complementary spiral shape before separation, and it is difficult to sufficiently recognize a difference in a design when separated and used. Was.

  Also, instead of the substantially circular spiral shape as in Patent Documents 1 and 2, the wound shape and width of the drug-containing material can be changed, and the design itself can be expressed by the shape of the drug-containing material itself. is there. However, if the width of the drug-containing body is changed, the amount of the drug volatilized during combustion cannot be kept constant, and it is not suitable for applications such as mosquito coils. In addition, if the design expression is made in such a shape that the drug-containing substance branches, the reproducibility of the burning time and the burning path becomes poor, which is not suitable for actual use. In addition, it cannot be formed by punching out a set of complementary shapes, and there is a problem that the amount of drug-containing substance per area cannot be secured and the package becomes large.

  Furthermore, while keeping the width of the drug-containing substance substantially constant, it can be formed into a star shape, a heart shape, a character shape, or the like by including a large number of corners or curves to express various design shapes. However, it is assumed that the drug-containing substance is used for a long period of several months to several years. In particular, there is a possibility that the drug-containing substance is exposed to a humid space with the package opened and stored. In such poor storage conditions, the drug-containing body may expand and contract due to moisture absorption.

  In the case of the conventional substantially circular spiral shape, even if the drug-containing body expands and contracts due to moisture absorption, the expansion and contraction direction is the stretching direction of the drug-containing body, so that the spiral shape is maintained. However, when a design is expressed by including a large number of corners and curves, the expansion and contraction due to moisture absorption is not uniform, and the original design may be deformed. When such deformation occurs, not only the expression on the design surface cannot be maintained, but also the gaps shrink and the drug-containing bodies come into contact with each other, which may cause a problem such as multi-point ignition in which a plurality of places are burned simultaneously.

  The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a drug-containing substance that can suppress the occurrence of problems such as multipoint ignition while improving the degree of freedom of expression in design. With the goal.

  In order to solve the above problem, the drug-containing body of the present invention is a drug-containing body formed by winding a single path from the end holding portion near the center to the ignition point portion, and the vicinity of the center has a basic shape. It is a wound basic winding part, has a bent part whose curvature changes outside the basic winding part, and is provided with a design part deviating from the basic shape by the bent part.

  This makes it possible to suppress the shape change due to expansion and contraction due to moisture absorption, etc. by providing a design part outside the basic winding part with the vicinity of the center as the basic winding part, while improving the freedom of expression on the design, multipoint ignition etc. Can be suppressed from occurring.

  In one embodiment of the present invention, the basic winding portion has a spiral shape based on a substantially circular or substantially elliptical shape.

  Advantageous Effects of Invention According to the present invention, it is possible to provide a drug-containing substance that can suppress the occurrence of problems such as multipoint ignition while improving the degree of freedom of expression in design.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or equivalent components, members, and processes shown in the drawings are denoted by the same reference numerals, and the repeated description will be omitted as appropriate. FIG. 1 is a schematic plan view showing a state in which a pair of complementary drug-containing bodies in the present embodiment is separated, and FIG. 1 (a) shows one winding shape, and FIG. 1 (b). Indicates the other winding shape.

  As shown in FIGS. 1 (a) and 1 (b), the medicine-containing body of the present embodiment has a single piece from the end holding portion 11 which is the end near the center to the ignition point 12 which is the outermost end. The path is wound and has a substantially constant width. The basic winding portion 13 is wound in a substantially circular basic shape over a predetermined length from the vicinity of the center, and a bent portion 14 whose curvature changes is formed outside the basic winding portion 13. ing. Due to the formation of the bent portion 14, the path of the drug-containing body deviates from the basic shape and forms the design portion 15.

  The components of the drug-containing body are not particularly limited, and the components of the drug and the components of the molding material are mixed and dried. The components of the drug include various insecticidal and repellent components. For example, pyrethrum extract, natural pyrethrin, pralethrin, imiprothrin, phthalthrin, allethrin, transfluthrin, resmethrin, phenothrin, cyfenothrin, permethrin, cypermethrin, etofenprox, cyfluthrin, deltamethrin, bifenthrin, fenvalerate, fenpropathrin, empenthrin, empenthrin Pyrethroid compounds such as silafluofen, methfluthrin, and profluthrin; organic phosphorus compounds such as fenitrothion, diazinon, marathon, pyridafenthion, prothiophos, foxime, chlorpyrifos, dichlorvos; carbamate compounds such as carbaryl, propoxur, mesomil, and thiodicarb; Diazole compounds; phenyl such as fipronil Lupyrazole compounds; Sulfonamide compounds such as amidoflumet; Neonicotinoid compounds such as dinotefuran and imidacloprid; Insect growth controlling compounds such as methoprene, hydroprene and pyriproxyfen; Pyrrole compounds such as chlorfenapyr; Essential insecticides such as diet, di-n-butyl succinate, hydroxyanisole, ethyl-butylacetylaminopropionate, p-menthane-3,8-diol, citronella oil, eucalyptus oil, geranium oil, moon peach Repellents such as oil and mosquito repellents can be mentioned.

  Further, as a component of the molding material, for example, a combustion base material (combustion agent) and the like can be mentioned. Examples of the burning base material (supporting agent) include wood powder, tea leaf powder, coffee bean shell endothelial powder, corn core powder, suga, hemlock, oak, coconut, bamboo, coconut, tangerine, and other woody species. Fibers such as powder, cotton, kenaf, flax and the like can be mentioned.

  The end holding part 11 is an end located near the center of the medicine-containing body, and is the end that burns last when burned from the outside. Further, a cut for inserting a device for holding the drug-containing substance may be formed at the center, and may be formed wider than other regions to form a cut. Further, FIGS. 1A and 1B show an example in which the end holding portion 11 is formed in a substantially semicircular shape, but the shape is not particularly limited.

  The ignition point portion 12 is an end located at the outermost periphery of the drug-containing material, and is a terminal that ignites when the drug-containing material is burned. As shown in FIGS. 1 (a) and 1 (b), the ignition point portion 12 has an acute angle at the extreme end so as to be easily ignited, and is formed on an end face cut obliquely to the width direction.

  The basic winding portion 13 is a spiral-shaped region wound in the basic shape, and is formed continuously from the end holding portion 11 over a predetermined length. The predetermined length of the basic winding portion 13 is preferably at least 10% or more, more preferably 30% or more of the entire length from the end holding portion 11 to the ignition point portion 12. The design method of the basic shape will be described later with reference to FIG. Although the basic shape may be a substantially circular shape or a substantially elliptical shape, a substantially circular shape is most preferable in order to effectively suppress deformation due to expansion and contraction due to moisture absorption.

  The bending portion 14 is a portion that deviates from the basic shape due to a change in curvature, and is provided outside the basic winding portion 13. By providing a plurality of bent portions 14, the path of the medicine-containing body deviates from the basic shape of the basic winding portion 13 to form the design portion 15. In the example shown in FIGS. 1A and 1B, the bent portion 14 includes an outward deviation portion 14 a extending in an outer peripheral direction and an inward deviation portion 14 b extending in an inner peripheral direction, and imitates a cat's ear. It expresses a design. By providing the outward deviation portion 14a and the inward deviation portion 14b in each of the plurality of bent portions 14, the degree of freedom of expression in the design is improved.

  In the example shown in FIG. 1A, the ignition point portion 12 is located outside the bent portion 14, but the route of the medicine-containing substance located outside the design portion is relatively short, and the design portion 15 It is warped almost parallel or outward. In the example shown in FIG. 1B, the bent portion 14 and the design portion 15 formed by the bent portion 14 are located outside and outside the basic winding portion 13, and the ignition point portion 12 is Is located outside. Thereby, even if the medicine-containing body expands and contracts due to moisture absorption, it is possible to prevent the ignition point portion 12 from coming into contact with the design portion 15 due to deformation and causing multipoint ignition.

  Next, a design method of the basic shape will be described with reference to FIG. FIG. 2 is a schematic diagram illustrating a substantially circular winding shape as a basic shape. First, a concentric circle of 1, 2, 3,... Of the basic radius is drawn, and a spiral curve is drawn by connecting the 0-degree, 90-degree, 180-degree, and 270-degree positions in order. A curve shown by a solid line in the drawing becomes an outer line in the width direction of the spiral shape shown in FIG. 1A, and a spiral shape having a width of a basic radius can be formed. In addition, what is obtained by rotating the spiral shape shown in the figure by 180 degrees becomes a complementary spiral shape. FIG. 2 shows a case where the basic shape is a circle. However, when the basic shape is an ellipse, an ellipse is used instead of a concentric circle. It should be noted that the diagram shown in FIG. 2 schematically shows the concept of the basic shape, and does not strictly define a geometric shape, but may be any similar shape.

(Comparative example)
A plurality of drug-containing bodies constituting the design portion 15 were molded from the vicinity of the center, and stored in an opened state for several days to perform a combustion experiment. FIG. 3 is a photograph substituted for a drawing showing a combustion process of Comparative Example 1. FIG. 4 is a drawing substitute photograph showing a combustion process of Comparative Example 2. Comparative Example 1 shown in FIG. 3 and Comparative Example 2 shown in FIG. 4 have complementary shapes obtained by stamping out a flat drug-containing substance. As shown in FIGS. 3 and 4, Comparative Examples 1 and 2 simulate a heart shape A, a petal shape, and an animal shape A, in which a bent portion 14 is formed immediately before the end holding portion 11 near the center. And a shape in which the substantially circular or substantially elliptical basic winding portion 13 does not exist.

  3 and 4, the photographs shown in (a) show the state before ignition, and the photographs in (b) to (f) show the time-dependent changes after ignition. The part of the photograph where the drug substance is turned white is burnt ash. As shown in FIGS. 3 and 4, in Comparative Examples 1 and 2, the drug-containing substance expands and contracts due to moisture absorption before combustion, and some of the outermost paths contact the inner paths.

  3 (f) and 4 (f), those marked with a cross are defective products in which multipoint ignition has occurred. This is a faulty product that is in contact and may cause multipoint ignition or extinguishing. As shown in FIGS. 3 and 4, the deformation of the medicine-containing body due to moisture absorption differs depending on the storage state and the state of moisture absorption, and thus, in all of Comparative Examples 1 and 2, multipoint ignition and extinguishing do not occur. . However, since the design portion 15 is formed by forming the bent portion 14 from the vicinity of the center, it is found that there is also a case where the deformation amount due to moisture absorption is large and defects such as multipoint ignition and extinguishing may occur. Was.

(Example)
A basic wound portion 13 is formed in the vicinity of the center, and a plurality of drug-containing bodies comprising the bent portion 14 and the design portion 15 outside the basic wound portion 13 are formed into a plurality of patterns. Was done. FIG. 5 is a drawing-substitute photograph showing the combustion process of Example 1. FIG. 6 is a photograph as a drawing showing the combustion process of Example 2. Example 1 shown in FIG. 5 and Example 2 shown in FIG. 6 have complementary shapes obtained by stamping out a flat drug-containing substance. As shown in FIGS. 5 and 6, the first and second embodiments simulate an animal shape B, a heart shape B, and an animal shape C, and have a substantially circular shape with a predetermined length from the end holding portion 11 near the center. This is the shape in which the basic winding portion 13 which is the basic shape of the above is formed.

  5 and 6, the photographs shown in (a) show the state before ignition, and the photographs in (b) to (f) show the time-dependent changes after ignition. The part of the photograph where the drug substance is turned white is burnt ash. As shown in FIGS. 5 and 6, even in Examples 1 and 2, the drug-containing material was expanded and contracted due to moisture absorption before combustion, but the deformation amount was smaller than Comparative Examples 1 and 2, and the outermost route. Is not in contact with the inner path.

  As shown in FIGS. 5 (f) and 6 (f), in Examples 1 and 2, the path of the outer periphery is not in contact with the inner periphery due to the deformation of the drug-containing substance, and is bent to the basic winding portion 13. Even when the part 14 and the design part 15 burn, no multipoint ignition or extinguishing occurs. Thus, since the bent portion 14 is not provided in the vicinity of the center and the basic winding portion 13 is formed, the amount of deformation due to moisture absorption is reduced, and it is possible to suppress defects such as multipoint ignition and extinguishing.

  FIG. 7 is a drawing substitute photograph showing the state of multipoint ignition that occurred in Comparative Examples 1 and 2. As shown in FIGS. 7A to 7D, combustion continues along the path from the ignition point portion 12, but in a portion where the amount of deformation is large and comes into contact with the inner path, the outer path burns. The inner path is ignited. As shown in FIG. 7C, when the inner path is completely ignited, the combustion of the inner path proceeds in the direction of the end holding section 11 and the direction of the ignition point section 12 by multipoint ignition. When such multipoint ignition occurs, the time required to burn the length from the ignition point portion 12 to the end holding portion 11 cannot be secured, and the combustion continuation time is shortened. In addition, since the amount of combustion is large during the period of multipoint ignition, the amount of chemical vaporization increases.

  FIG. 7 shows an example of multipoint ignition. However, if the outer path and the inner path are in contact with each other, the temperature required for supplying and burning oxygen to the outer path is insufficient, and the combustion of the outer path is not performed. There is also a possibility that the extinction will end.

  Therefore, in the medicine-containing body of the present embodiment, by changing the vicinity of the center to the basic winding portion 13 and providing the design portion 15 outside the basic winding portion 13, the shape change due to expansion and contraction due to moisture absorption and the like can be suppressed, and the expression on the design While improving the degree of freedom, it is possible to suppress the occurrence of problems such as multipoint ignition and extinguishing.

  The present invention is not limited to the embodiments described above, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
