A method for producing a volatile substance discharger, wherein the opening of a container is sealed with a sealing member.

  In the present invention, the container filled with the holding medium for holding the volatile substance is a container having an inner wall with a large surface area, and is a material having shape-retaining properties such as glass in addition to hard plastic such as polyolefin, polyacrylate, and polycarbonate. To a container having a multi-surface inner wall. The material of the container is not limited as long as it can be held by filling the holding medium inside the container, but is preferably not welded to the holding medium so that the holding medium becomes peelable. Plastics such as non-polar polyolefins such as polyethylene and polypropylene are preferable because they have a low adhesiveness, and thus widen the region where the holding medium exhibits peelability. The container can be highly decorative if it is transparent or translucent, but may be opaque.

  Although the container has a multi-surface area inner wall, in order to make the inner wall a multi-surface area structure, a multi-surface area structure can be formed by forming a plurality of chambers in the container. It is also possible to form a part to have a multi-surface area structure. In the case of forming a plurality of chambers, it is preferable that a plurality of subdivided chambers (partitioned recesses) extend in different directions from one or a plurality of connecting recesses to form a multi-surface area structure. The connecting recesses and subdividing chambers are each composed of a continuous groove, so that the manufacture is easy and the gel can be aggregated during use. However, the connecting recesses and the subdividing chambers can be composed of recesses such as circles, polygons, and irregular shapes. it can. The direction in which the plurality of subdivision chambers extend from the connecting concave portion may be different directions, but generally, the radial direction is preferable, and in the case of two directions, the direction of 180 degrees is preferable.

  The chamber in which the inner wall of the container has a multi-surface area structure preferably does not have a right-angled or acute-angled corner, and the corner is formed by a curved surface. For this reason, the concave portion constituting the chamber is preferably composed of a continuous curved surface or a surface in which the curved surface and a flat surface are continuous as an overall shape. If a corner portion having a right angle or an acute angle is formed on the inner wall, the holding medium is difficult to be peeled off. However, if the corner portion has an obtuse angle shape larger than the right angle, the peeling may be easily performed. Moreover, the convex part for forming several recessed part, ie, the convex part formed between several recessed parts, may be right-angled or acute-angle shape.

  The container preferably has a structure that can stand by itself with the opening side or the opposite side as the bottom. When the container has a multi-surface area structure by a plurality of chambers (recesses), the same depth is obtained by making the depths of at least three, preferably four or more chambers (recesses) among the plurality of chambers the same. It can be set as the structure which the bottom part of a recessed part of can support a volatile substance discharge device and can become independent. The inner wall on the opposite side of the opening becomes a recess, and by supporting it at the bottom, the volatile substance can be released with the opening facing up, but the container is supported with the container opening facing down. By providing the ventilation member, the volatile substance can be released with the opening of the container facing down.

  The overall planar shape seen from the opening side of the container can be a quadrilateral or other square shape, but can also be a circle, ellipse, oval, oval, or any other shape. As described above, the planar shape or the vertical cross-sectional shape of the concave portion having a multi-surface area structure preferably has no right-angle or acute-angle corner portion. In the case of a structure in which a plurality of subdivision chambers extend in different directions from the connection recess, either the connection recess or the divided chamber may be deeper, but when the gel is injected into the connection recess, the plurality of subdivision chambers from the connection recess It is preferable to have a structure in which gels are separated and flown into.

  In the present invention, the volatile substance held in the holding medium is a substance released from the holding medium into the atmosphere by volatilization, and examples include a volatile fragrance, a fragrance, a deodorant, an insect repellent component, and a drug component. It is done. These volatile components may be water-soluble or oil-soluble, but uniformly dissolve or disperse in the gel as the holding medium to form a transparent gel molded body, which easily penetrates and volatilizes the surface of the gel Is preferred.

  The holding medium for holding such a volatile substance is made of a gel molded body, but is preferably made of a peelable gel molded body so that the holding medium becomes peelable. That the holding medium is peelable means that the holding medium can be peeled from the container when the container is filled with the holding medium. Here, being peelable means that there is a relative relationship between the holding medium and the container, and the adhesiveness or peelability of the holding medium and the container appears in combination. For this reason, when the adhesiveness of the container is low, it may become peelable even if the adhesiveness of the holding medium is high. Those having low properties are preferred.

  The holding medium is made of a gel molded body, and a gel that dissolves and holds a volatile substance is used. As the gel component forming such a gel, known gels such as gelatin, carrageenan, agar, starch, CMC, oil gel, water-absorbing polymer, polyfunctional acid and polyol polycondensation gel are used. An aqueous gel that is dissolved and retained in water is preferred. Any of the above gels can be made peelable without special treatment when filled in a low adhesion container such as polyolefin, but a gel with high adhesion like gelatin, By performing the treatment for reducing the adhesiveness such as cross-linking, the container having high adhesiveness can be made peelable.

  Since the holding medium is used in a state where it is filled in a container, as long as the upper surface of the holding medium is used in a horizontal state, shape retention of the holding medium is not required, but it is used with the upper surface of the holding medium inclined. In this case, it is preferable that the holding medium has shape holding property. As the holding medium having shape-retaining properties, a crosslinked gelatin aqueous gel molded body is preferable. In particular, a transparent gelatin aqueous gel molded body having a jelly strength of 15 or more, which is a reaction product of an aqueous sol containing gelatin, a crosslinking agent and a volatile component. preferable. Such a crosslinked gelatin aqueous gel molded article is transparent and peelable, does not separate moisture, has excellent shape retention, and can retain its shape even when formed into a large surface shape. .

  A volatile material having such a structure that a gel holding such a volatile substance is filled into the container from the opening side, a peelable holding medium made of a gel molded body is formed, and the inner surface of the container has a large surface area. Although a substance discharger is formed, a gap may be formed on the opening side. The shape of the opening of the container is preferably a shape in which the gelatin aqueous gel easily contracts to the center side of the opening with the release of the volatile substance, and the opening surface can be a horizontal surface, From a surface such as accommodation, an inclined surface or other shapes may be used. When a space part is formed on the upper part of the holding medium filled in the container, the space part may be filled with a filling material, or may be empty without being filled with anything.

  The above holding medium is prepared by injecting a sol containing a gel material and a volatile component into a container from an opening, filling the gel so as to be in contact with the inner wall of the large surface area, and gelling, thereby forming a gel molded body holding a volatile substance. To form a holding medium. When a plurality of chambers are formed by a plurality of recesses formed on the inner wall of the container and have a multi-surface area structure, the respective chambers (recesses) are filled, but the subdivision chambers are different from the connection recesses. In the case of a structure that extends to, by injecting a sol containing a gel material and a volatile component into the connecting recess, the injected sol is divided into a plurality of subdividing chambers and filled into the entire chamber (recess), and the gel To form a holding medium. For this reason, in a structure in which a large number of subdivision chambers branch from one connecting recess, it is possible to fill a number of subdivision chambers and gel by simply injecting sol into one connecting recess. A holding medium can be formed efficiently.

  When forming a cross-linked gelatin aqueous gel molding, an aqueous sol containing gelatin, a cross-linking agent and a volatile component is injected into the container from the opening side and reacted to fill the container and adhere to the inner wall of a large surface area. A peelable cross-linked gelatin aqueous gel molded product having the above structure is formed. After filling with the aqueous sol or after completion of the reaction, the volatile substance discharger is obtained by sealing the opening of the container with a sealing member. When the ventilation member is provided, the ventilation member having a ventilation hole and covering the opening of the container may be a product in a state of being attached to the opening of the container, or may be a product without being attached.

  The peelable gelatin aqueous gel used in the present invention has a high molecular weight gelatin having a molecular weight of 100,000 or more and less than 500,000, preferably 2 to 4% by weight, preferably 2 to 4% by weight, and a molecular weight of 3,000 or more. Low molecular weight gelatin less than 000 0.05 to 0.5 wt%, preferably 0.1 to 0.4 wt%, crosslinker 0.1 to 1 wt%, preferably 0.4 to 0.8 wt%, Preferred is an aqueous gelatin gel comprising an aqueous sol reaction product containing 0.5 to 10% by weight, and preferably 1 to 8% by weight of a volatile component. The aqueous sol preferably contains 0.1 to 5% by weight, preferably 0.2 to 4% by weight, of a medium molecular weight gelatin having a molecular weight of 10,000 or more and less than 100,000.

  As can be seen from the fact that gelatin is used as an adhesive in glue, it has excellent adhesion, so when it is molded into a complicated shape, it is difficult to release the mold and to release it due to shrinkage of the holding medium. When a gelatin mixture containing a low molecular weight gelatin of 3,000 or more and less than 10,000 is used, the releasability and peelability are improved. For this reason, even when a container having a complicated shape is used, it is possible to separate the holding medium due to shrinkage. Even when this gel molded body is used with the opening of the container down, the gel molded body does not flow out of the opening only by its own weight, and can be held in the container. Thereby, when it is used with the opening side as the bottom, it is possible to improve the holding property of the holding medium.

  Any crosslinking agent may be used as long as it can react with a functional group of gelatin to crosslink, but an ethylenically unsaturated compound-maleic anhydride copolymer, a ring-opening polymer thereof or a salt thereof is preferable. Examples of the ethylenically unsaturated compound include olefins such as ethylene, propylene, butene-1, butene-2, and isobutylene, and other compounds having an ethylenically unsaturated group. The ring-opening polymer is a polymer opened by adding water to an ethylenically unsaturated compound-maleic anhydride copolymer, and the salt thereof is a salt such as an ammonium salt or a sodium salt of the ring-opening polymer. The salt can be formed by reacting the above acid copolymer or ring-opening polymer with ammonium hydroxide or sodium hydroxide salt.

  The above strippable gelatin aqueous gel is a reaction product of an aqueous sol containing these gelatin, a cross-linking agent and a volatile component. The gelatin and the cross-linking agent are volatile components, an aqueous solvent, and other components added as necessary. It is a peelable transparent cross-linked gelatin aqueous gel molded article made of a reaction product that cross-links by reacting so as to embrace and form an aqueous gel. Such a peelable gelatin aqueous gel can be produced by reacting the aqueous sol at 20 to 70 ° C., preferably at room temperature to 60 ° C. The peelable gelatin aqueous gel formed in this way is an aqueous gel in which gelatin is crosslinked in a state of embracing a volatile component, an aqueous solvent, and other components added as necessary, even when the concentration of the gel forming agent is low. In addition, it is possible to form a molded body having excellent shape retention.

  A preferred method for producing the peelable gelatin aqueous gel of the present invention is 1.5 to 5% by weight of high molecular weight gelatin, preferably 2 to 4% by weight, 0.1 to 5% by weight of medium molecular weight gelatin, preferably 0.2%. -4 wt%, low molecular weight gelatin 0.05-0.5 wt%, preferably 0.1-0.4 wt%, cross-linking agent 0.1-1 wt%, preferably 0.4-0.8 wt% %, And 0.5 to 10% by weight of volatile components, preferably 1 to 8% by weight, and other components 0 to 20% by weight, preferably 0.5 to 10% by weight, if necessary Can be produced as a peelable gelatin aqueous gel molded body by reacting with.

  The peelable gelatin aqueous gel produced in this way has high gel strength even when the gelatin concentration is low, and high shape-retaining properties that can maintain the shape over a long period of time at room temperature or high temperature in an unused or used state. A shape-retaining gelatin aqueous gel is obtained that is free from moisture separation, has high volatility of volatile components, is transparent, and has high decorative properties. The jelly strength of the gelatin aqueous gel is 15 or more, preferably 20 or more.

  In the volatile substance discharger according to the present invention, in a state before use, a container containing a peelable gel-like holding medium containing a volatile substance is sealed with a seal member. In a state before use, the container may be in a state in which the opening is up or in a state in which the opening is down. When the ventilation member is provided, the ventilation member may be attached to the opening of the container or may not be attached, and can be a product in any state.

  When using the above volatile substance release device, usually the seal member is peeled off from the container and the container opening is used with the container opening up, but in some cases the container opening is down or It can be used in an inclined state. When equipped with a ventilation member, peel off the sealing member from the container, cover the container opening with the ventilation member with the container opening up, or incline, or vent the container with the container opening down. It can be used in a state supported by the member.

  In use, the holding medium in the container comes into contact with the atmosphere through the opening of the container and the ventilation hole of the ventilation member, and volatile components such as fragrances and insect repellent components contained in the holding medium enter the atmosphere from the surface of the gel. Volatilizes and functions as a fragrance or insect repellent. Immediately after the start of use, the volatile substance is released only from the opening side surface of the holding medium filled in the container, but when the volatilization progresses and the gel contracts, the gel peels off from the inner wall of the container due to its peelability. Volatilization occurs from the peeled portion, and the surface area for volatilization increases. Peeling occurs gradually from a portion close to the surface of the gel, and the surface area gradually increases.

  At this time, the separation surface of the holding medium that has been in contact with the inner surface of the container having a large surface area has a large surface area, so that the contact area with the atmosphere increases, and the volatilization efficiency of the volatile material increases. By adjusting the surface area of the inner surface of the multi-surface area, that is, the shape of the inner wall of the container, the surface area where the gel is volatilized can be adjusted. Therefore, even when the volatilization area is narrow and the volatilization rate is low, the volatilization rate can be increased by increasing the surface area of the inner wall of the container. The amount of volatilization from the holding medium is often in the initial stage of use where the concentration of the volatile substance is high, and decreases as the usage time elapses, but the amount of volatile substance that decreases is increased by increasing the surface area due to peeling. be able to.

  When a multi-surface area structure is formed by a plurality of chambers (recesses) formed on the inner wall, the amount of the volatile substance can be adjusted by adjusting the shape, number, etc. of the chambers (recesses). In this case, by having a multi-surface area structure with a plurality of subdivision chambers extending in different directions from the connection recess, the gel can be concentrated in the connection recess when the holding medium contracts due to volatilization of the volatile material. The end point of the volatile substance emitter, that is, the replacement time is easily determined, and the aesthetic appearance is not impaired.

  As described above, in the present invention, by simply filling a peelable holding medium into a container having an inner wall having a large surface area, the release surface of the multiple surfaces is exposed by peeling due to shrinkage during use, and The volatilization rate can be increased, and the surface area where the gel is volatilized can be adjusted without using complicated molds for gel molding as shown in Fig. 3, and performing complicated operations or using special gels or containers. Easy to manufacture and control.

  By making the gelatin aqueous gel of the container and the holding medium transparent, the light hitting the volatile substance emitter is reflected through the container and the gel through transmission, refraction, and emission, so that an excellent aesthetic appearance is obtained. And the shape change of a holding medium accompanying discharge | release of a volatile substance, and a peeling state are observed through a container, and a volatile substance discharger with high unexpectedness and decoration is obtained.

  The volatile substance emitting device of the present invention is installed in a room, kitchen, closet, toilet, bathroom, automobile, refrigerator, and other places, and is used as a fragrance, deodorant, antibacterial agent, insect repellent, repellent, and other. It can be used as a volatile substance discharger for gradually releasing volatile substances.

  According to the present invention, a container having a multi-surface inner wall is filled with a peelable holding medium made of a gel molded body holding a volatile substance, and the opening of the container is sealed with a sealing member. Therefore, when releasing volatile substances such as fragrances and deodorants from the holding medium filled with volatile substances filled in the container, the surface area is easily increased with a simple structure and efficiently evaporated. Volatile substance discharger that can be released inside, can easily adjust the surface area to adjust the volatilization rate, and can use a medium with low shape retention, and its efficient production A method can be provided.

Equivalent sectional drawing, (d) is an EE equivalent sectional drawing which shows the state in use, and the same code | symbol as FIG. 3 shows the same or equivalent part.

  1 and 2, a volatile substance discharger 1 includes a peelable holding medium 2 made of a gel molded body holding a volatile substance in a chamber 14 of a transparent container 3 having an inner wall with a large surface area. Filled, the opening 11 of the container 3 is sealed with a sealing member 12, and a ventilation member 13 having a ventilation hole 17 is attached to the opening 11 of the container 3. The container 3 has a multi-surface area structure by a plurality of chambers (recesses) 14 formed in the inner wall 9. The chamber 14 has a multi-surface area structure by a plurality of subdivided chambers 16 extending in different directions from the connecting recess 15.

  In the chamber 14, in FIG. 1, the groove-shaped connecting recess 15 extends in the width direction at the center portion, and a plurality of groove-shaped subdivision chambers 16 extend in a direction of 180 degrees from a plurality of positions in the width direction, The whole constitutes a single chamber 14. The bottom of each subdividing chamber 16 extends in an inclined manner, and is configured to support the container at the lowest part. In FIG. 2, a plurality of short groove-shaped connecting recesses 15 are provided in the width direction in the central portion, and two groove-shaped subdividing chambers 16 extend from each connection recess 15 in the direction of 180 degrees, respectively. The chamber 14 is configured. The bottom surface of each subdividing chamber 16 extends at substantially the same height, and is configured to support the container at the lowest portion. The corners of the chamber 14, the connecting recess 15, and the subdividing chamber 16 are formed with curved surfaces.

  The holding medium 2 is made of a peelable transparent cross-linked gelatin aqueous gel molded body having a shape-holding property for holding a volatile substance, and has a gap from the opening 11 side to the chamber 14, the connecting recess 15, and the subdividing chamber 16 of the container 3. However, the gap 6 is slightly formed between the outer surface 5 on the opening 11 side and the seal member 12. The seal member 12 is fixed to the opening 11 so as to be peelable. The ventilation member 13 has a ventilation hole 17 in the peripheral wall and is detachably attached so as to cover the opening 11 of the container 3.

  Said volatile substance discharger 1 is manufactured as follows. First, an aqueous sol containing gelatin, a cross-linking agent and a volatile component is injected into the connecting recess 15 from the nozzle into the container 3 with the opening 11 on top, and further divided into a plurality of subdividing chambers 16 to each subdividing chamber 16. By reacting in the filled state, the container 3 has a structure in which the container 3 is filled without a gap from the opening 11 side and is in close contact with the inner wall of the container 3, and is formed of a shape-retaining transparent gelatin aqueous gel molded body having a jelly strength of 15 or more The holding medium 2 is formed. By adopting a structure in which the plurality of subdividing chambers 16 extend in different directions from the connecting recess 15 as described above, the holding medium 2 can be easily formed by one injection, and the manufacturing can be performed efficiently. .

  In this state, the opening 11 of the container 3 is sealed with the sealing member 12 and combined with the ventilation member 13, whereby the volatile substance emitter 1 is manufactured. The volatile substance discharger 1 is transported and stored as a product with the opening 11 facing upward, but may be reversed. The ventilation member 13 may be a product attached to the opening 11 of the container 3 or may be a product not attached.

  The volatile substance discharger 1 is used in a state where the opening 11 is covered with a ventilation member 13 as shown in FIGS. That is, it can be used in a state where the sealing member 12 of the container 3 is peeled off from the state of FIGS. 1 and 2 and is covered with the ventilation member 13 with the opening 11 of the container 3 facing upward. However, it may be used without the ventilation member 13.

  In the use state of the volatile substance discharger 1, the holding medium 2 in the container 3 comes into contact with the atmosphere through the opening 11 of the container 3 and the vent hole 17 of the ventilation member 13, and the fragrance contained in the holding medium 2 Volatile components such as insect repellents are volatilized into the atmosphere from the outer surface 5 of the holding medium 2 and function as fragrances, insect repellents and the like. Immediately after the start of use, the volatile substance is released only from the outer surface 5 on the opening 11 side of the holding medium 2 filled in the container 3, but when the volatilization progresses and the gel contracts, the holding medium 2 becomes peelable. Therefore, as shown in FIG. 1 and FIG. 2 (e), it peels from the inner wall 9 of the container 3, volatilization occurs from the peeled part, and the volatilized surface area increases. Peeling occurs gradually from a portion close to the surface of the gel, and the surface area gradually increases.

  At this time, since the separation surface of the holding medium 2 that has been in contact with the inner wall 9 having a large surface area of the container 3 has a large surface area, the contact area with the atmosphere increases, and the volatilization efficiency of the volatile material increases. By adjusting the surface area of the inner wall 9 having a large surface area, that is, the shape of the inner wall 9 of the container 3, the surface area on which the gel is volatilized can be adjusted. Therefore, even when the volatilization area is narrow and the volatilization rate is low, the volatilization rate can be increased by increasing the surface area of the inner wall 9 of the container 3. The amount volatilized from the holding medium 2 is often in the initial stage of use where the concentration of the volatile substance is high, and decreases as the usage time elapses. However, the amount of volatile substance that decreases is increased by increasing the surface area due to peeling. can do.

  In FIG. 1 and FIG. 2, since it has a multi-surface area structure by the several chamber 14 formed in the inner wall 9, the quantity of a volatile substance can be adjusted by adjusting the shape, number, etc. of the chamber 14. FIG. Here, as shown in FIGS. 1 and 2 (e), the holding medium 2 contracts due to the volatilization of the volatile substance by forming a multi-surface area structure by the plurality of subdividing chambers 16 extending in different directions from the connection recess 15. At this time, the gel can be concentrated in the connecting recess 15, which makes it easy to determine the end point of the volatile substance discharger 1, that is, the replacement time, and does not impair the beauty.

  By making the gelatin aqueous gel of the container 3 and the holding medium 2 transparent, the light rays that hit the volatile substance emitter 1 are transmitted through the gel of the container 3 and the holding medium 2, refracted, and reflected as it is emitted. Excellent aesthetics can be obtained. And the shape change of the holding | maintenance medium 2 accompanying discharge | release of a volatile substance, and a peeling state are observed through the container 3, and the volatile substance discharger 1 with high unexpectedness and decoration is obtained.

  Since the holding medium 2 is made of a peelable transparent gelatin aqueous gel molded body having shape retaining properties, the gel molded body can be used even when the container 3 is tilted or used with the opening 11 down. The gel molded body does not flow out of the opening only by its own weight but is held in the container 3. In addition, since the shape of the holding medium 2 is high, the shape of the molded body can be held over a long period of time, and even if the volatile components are volatilized and the volume is reduced, the shape is not destroyed and the original shape is maintained. As it is, the volume is reduced to a similar shape, and the appearance is not impaired.

  Examples will be described below. A container having a single chamber made of a rectangular parallelepiped having a length of 46 mm, a width of 104 mm, and a depth of 12 mm is used as the container of Comparative Example 1, and the container of Example 1 is subdivided on both sides of the connecting recess 15 of the chamber 14 in FIG. Seven chambers are formed, and three subdivided chambers 16 are formed on both sides of the connecting recess 15 of the chamber 14 in FIG. The container of the same volume as that of Comparative Example 1 is used, and as the container of Example 3, the connecting recess 15 of the chamber 14 does not exist in FIG. 2, and two independent subdividing chambers 16 are formed on one side. The following tests were conducted using a container having the same volume as 1.

  In the chambers of the transparent containers 3 of Examples 1 to 3 and Comparative Example 1, 2 parts by weight of high molecular weight gelatin having a molecular weight of 100,000 or more and less than 500,000 as a gelatin mixture, and a molecular weight of 3,000 or more and less than 10,000, respectively. 0.13 part by weight of low molecular weight gelatin and 0.37 part by weight of medium molecular weight gelatin having a molecular weight of 10,000 or more and less than 100,000, and a sodium hydroxide salt obtained by ring-opening an isobutene-maleic anhydride copolymer as a crosslinking agent (Average molecular weight 3,000 to 3,000,000) 0.74 parts by weight, fragrance 3 parts by weight, surfactant 6.50 parts by weight, water 87.26 parts by weight By carrying out the reaction and gelation, a holding medium 2 composed of 50 g of a peelable transparent gelatin aqueous gel molded body holding the volatile substance is formed, and the volatile substance is released. The vessel 1 was produced.

  The sealing member 12 of the volatile substance releaser 1 is peeled off, and the fragrance contained in the holding medium 2 filled in the container 3 is volatilized and released into the atmosphere. Table 1 shows the results of measuring the daily weight loss (g) in the process of shrinking and peeling of the shrinkage of the holding medium 2. In Table 1, the underline indicates the end point.

  According to the results of Table 1, Example 1 with more fragmentation ends in 9 days, Example 2 with the next largest number ends with 16 days, and Example 3 with the next largest number ends with 19 days, and comparison without fragmentation Example 1 ended at 23 days. From the above results, it can be seen that the volatilization rate can be increased by subdividing the chamber and making the inner wall a multi-surface area structure, and the volatilization rate can be adjusted by adjusting the surface area.

  Volatile substance release for gradual release of volatile substances such as fragrances, deodorants, antibacterial agents, insect repellents, repellents, etc. installed in rooms, kitchens, closets, bathrooms, cars, refrigerators, etc. Used as a vessel.
