  In the present invention, the container filled with the holding medium for holding the volatile substance is a transparent container having an opening having a smaller diameter than the maximum diameter part, and from a transparent material having shape-retaining properties such as hard transparent plastic and glass, It is formed in a container shape having an opening. The transparent material has transparency that can be seen through from the outside, and may be colorless or colored and transparent. The container preferably has a structure that can stand by itself with the opening side or the opposite side as the bottom. The inner wall of the container preferably does not have a right-angled or acute-angled corner portion, and is particularly preferably a continuous curved surface or a surface consisting of a curved surface and a flat surface. If the right-angled or acute-angled corner portion is formed on the inner wall, the holding medium is difficult to peel off. However, if the corner portion has an obtuse-angled shape that is larger than the right-angle, peeling becomes easy.

  The container is preferably configured to gradually increase in diameter from the inner wall on the opposite side of the opening toward the maximum diameter, and gradually decrease in diameter from the maximum diameter toward the opening. While peeling becomes easy, the holding | maintenance property of a holding | maintenance medium at the time of using it by making an opening part side stand as a bottom part can be improved. The front shape (vertical cross-sectional shape) viewed from the front of the container and the planar shape (horizontal cross-sectional shape) viewed from the opening side are preferably continuous linear shapes having no right angle or acute angle portions, particularly circular, Oval, oval, oval, or similar smooth shapes are preferred.

  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 gelatin aqueous gel, which is a holding medium, to form a transparent gel molded body, which easily penetrates and volatilizes the surface of the gel. Those that do are preferred.

The concave holding medium and / or the independent holding medium for holding such a volatile substance are each made of a peelable transparent gelatin aqueous gel molded body. In particular, the concave holding medium is a medium that is released along with the release of the volatile substance. It is formed from a transparent gelatin aqueous gel molded body having a peelable and shape-retaining property that peels from the container when shrinking . The peelable transparent gelatin aqueous gel molded body as a holding medium is preferably a cross-linked transparent crosslinked gelatin aqueous gel molded body having shape retaining property and peelability, particularly reaction of an aqueous sol containing gelatin, a crosslinking agent and a volatile component. A transparent gelatin aqueous gel molded article having a jelly strength of 15 or more is preferred. Such an aqueous gelatin gel product does not separate moisture, is excellent in shape retention, and can retain its shape even when formed into a large surface shape.

A concave holding medium made of a peelable transparent gelatin aqueous gel molded body holding such a volatile substance is peeled off from the container when the medium shrinks as the volatile substance is released, and is opened in a transparent container. Although it has a structure in which it is filled without a gap from the part side and is in close contact with the inner wall of the container, a gap may be formed on the opening side. The recessed holding medium filled in this way has a recess formed by a forming mold for forming a recess at a depth that does not reach the inner wall on the opposite side of the container from the opening side of the container, thereby forming a large surface shape. This increases the contact area with the atmosphere. The recess preferably has an opening having the same or a small diameter as the opening of the container. The opening of the recess may be of a size that allows the gelatin aqueous gel in the periphery to shrink toward the center of the opening and release from the container with the release of the volatile substance, and the shape and dimensions of the container and the recess. varies depending on the like, typically that having a diameter of more than 10 mm.

  The shape of the recess and 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. The horizontal cross section of the recess and the shape of the opening are circular. Oval, oval, oval, or similar smooth shapes are preferred, but other shapes such as squares may be used. The thickness of the upper surface of the concave holding medium from the inner wall of the container to the opening of the recess in the opening of the container varies depending on the shape and dimensions of the container and the recess, but is generally preferably 50 mm or less.

  Such a concave portion of the concave holding medium may be filled with a filling material, or may be empty without being filled with anything. There is no restriction | limiting as a filler, There exist arbitrary things, such as a mascot, such as a flower, a doll, and an animal. As a filling, it is possible to fill an independent holding medium composed of a peelable transparent gelatin aqueous gel molded body of the same type or different from the concave holding medium, in this case, a peelable transparent gelatin aqueous solution holding a volatile substance. Filling an independent holding medium made of a gel-molded body is preferable because the holding amount of the volatile substance is increased and the released amount is also increased. When each of the concave holding medium and the independent holding medium is formed of a peelable transparent gelatin aqueous gel molded product, each shrinks in a separated state, and the shrinkage of the independent holding medium is accommodated in the shrinkage of the concave holding medium. .

  The above concave holding medium is transparent by placing an aqueous sol containing gelatin, a cross-linking agent and a volatile component in a transparent container and reacting in a state where a mold for forming a concave is inserted into the aqueous sol from the opening side. An exfoliating transparent cross-linked gelatin aqueous solution having a structure that has a structure in which a container is filled with no gap from the opening side and is in close contact with the inner wall of the container, and a recess is formed on the opening side and has a jelly strength of 15 or more A gel compact is formed. After completion of the reaction, the concave holding medium is formed by removing the mold from the opening side. The independent holding medium is formed in the same manner using a separate concave mold. A volatile substance discharger can be obtained by filling the concave portion of the concave holding medium with an independent holding medium or other filling material or by sealing the opening of the container with a sealing member without filling. In the case of including a ventilation member, a ventilation member that has a ventilation hole and supports the container with the opening of the container facing down, or a ventilation member that covers the opening of the container with the opening of the container facing up, It is good also as a product in the state attached to the opening part, and it is good also as a product in the state which is not 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 molding die for forming a concave portion having a complicated shape is used, it is possible to easily perform die cutting without damaging the gel molded body, and a concave portion having a complicated shape can be formed. Peeling accompanying shrinkage is possible. 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. In particular, it is preferable that the opening has a smaller diameter than the maximum diameter portion of the container, and this makes it possible to improve the holding ability of the holding medium when the opening side is used as a bottom portion.

  Since the molecular weight of gelatin varies depending on denaturation conditions, for example, the type and concentration of drugs and auxiliaries used for denaturation, temperature, time, and the like, gelatin having the desired molecular weight can be obtained by selecting denaturation conditions. The average molecular weight of gelatin can be determined by measuring the molecular weight distribution according to the Pagii method ninth edition (2002). The strength of the gel that serves as an index of shape retention can be measured as jelly strength according to JIS K 6503.

  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 ethylenically unsaturated compound-maleic anhydride copolymer is a copolymer of these ethylenically unsaturated compounds and maleic anhydride, and the molar ratio of the ethylenically unsaturated compound and maleic anhydride is 10: 1 to 1. 1:10, preferably 5: 1 to 1: 5, and the average molecular weight is usually 2,000 to 5,000,000, preferably 3,000 to 3,000,000. A commercially available product is used as such an ethylenically unsaturated compound-maleic anhydride copolymer. The ratio of ring-opening polymer, ammonium salt, sodium salt, or the like for ring-opening or conversion to a salt is arbitrary, but it is preferable to convert all of the anhydrous rings.

  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 of the present invention produced in this way has high gel strength even when the gelatin concentration is low, and can be used at room temperature or high temperature even when molded into a complicated shape having a large surface area such as a molded article having a cavity. High shape retention that can hold the shape for a long time in an unused or used state, moisture is not separated, volatile components are highly volatile, and transparent and highly decorative Aqueous gelatin gel is obtained. 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 a volatilizing substance discharger, it is better to use with the container opening facing upward, because the shrinkage of the concave holding medium peels off in a basket shape, and when the filling is filled in the recess. In the state where the filling material is filled in the concave portion, the shrinkage of the concave holding medium is peeled off, so that it is surprising and decorative, but it can be used with the opening of the container down. Also good. When using the opening of the container while the lower, as filler does not fall, the position of the seal member, or near, Ru provided packing holding member such as a screen.

  When using said volatile substance discharger, it peels off a sealing member from a container, and uses it in the state which opened the container opening part, or the state which opened the container opening part. When the ventilation member is provided, the sealing member is peeled off from the container and the container opening is covered with the ventilation member with the container opening facing up, or the container is supported by the ventilation member with the container opening facing down Used in.

  At this time, the holding medium in the container comes into contact with the atmosphere through the opening of the container and the vent of the ventilation member, and volatile components such as fragrances and insect repellents contained in the holding medium are volatilized from the surface of the gel into the atmosphere. And functions as a fragrance, insect repellent, etc. Since the concave holding medium has a large surface shape with a recess formed at a depth that does not reach the inner wall of the container from the opening side of the container, the contact area with the atmosphere increases, and volatile substances are efficiently volatilized. It is made to discharge | release to air | atmosphere, and functions, such as provision of fragrance and deodorizing, can be maintained for a long time. In addition, when the independent holding medium is filled, since the independent holding medium is formed in an independent state, it is possible to further increase the volatilization efficiency of the volatile substance by further increasing the contact area with the atmosphere.

  Further, since the gelatin aqueous gel of the container and the holding medium is 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 and peeling state of a holding | maintenance medium accompanying discharge | release of a volatile substance are observed through a container. That is, with the release of the volatile material, the concave holding medium contracts in a similar manner, and the contracted material is peeled off little by little, and finally peeled off completely in a basket shape. By using a container having an opening having a diameter smaller than the maximum diameter portion, the contracted material contracts toward the center of the opening, so that the contracted material can be easily peeled off. The inner wall of the container does not have a right-angled or acute-angled corner, particularly a continuous curved surface, or a surface consisting of a curved surface and a flat surface, for example, the vertical cross-sectional shape and horizontal cross-sectional shape of the container are perpendicular or acute, respectively. Even when a continuous linear shape having no part, particularly a circular shape, an elliptical shape, an oval shape, an oval shape, or a smooth shape similar to these, and when the opening of the concave portion has a diameter of 10 mm or more, The shrinkage can be easily peeled off.

  When the concave portion of the concave holding medium is filled with the filler, the shrinkage of the concave holding medium is peeled off in a state where the filler is filled in the concave portion. When the filler is an independent holding medium, the independent holding medium also contracts, and the contracted substance of the concave holding medium is peeled in a state where the contracted substance is filled in the recess. Such a shape change and peeling state of the holding medium are observed from the outside through the container, and a volatile substance discharger with high unexpectedness and decorativeness is obtained. When the container is used with the opening portion down, a filler holding member such as a screen can be provided at or near the position of the seal member, and the filler can be supported by the filler holding member.

  Since the above-mentioned holding medium has shape-retaining properties, the gel molded body does not flow out of the opening of the container only by its own weight, and can be held in the container to release the volatile substance. Further, since the opening is filled in a container having a diameter smaller than the maximum diameter part of the container, the holding medium retainability is high even when the opening side is used as a bottom part. In addition, since the shape of the holding medium is high, the shape of the molded body can be maintained 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 decreases to a similar shape and peels off, and the aesthetic appearance is not impaired.

According to the volatile substance discharger of the present invention, the volatile substance is held in a transparent container having an opening having a diameter smaller than the maximum diameter part, and peeled off from the container when the medium contracts as the volatile substance is released. It is filled with a concave holding medium made of a transparent gelatin aqueous gel molded body having peelability and shape retention, and an opening having a depth not reaching the inner wall on the opposite side of the container from the opening has a diameter of 10 mm or more. In addition, a recess having a shape in which the medium contracts toward the center side with the release of the volatile substance is formed on the holding medium by a mold for forming the recess, and the sealing member is peeled off to volatilize the volatile substance. Therefore, volatile substances such as fragrances and deodorants contained in the holding medium are efficiently volatilized and released into the atmosphere while preventing the holding medium itself containing the volatile substance filled in the container from flowing out. Fragrance, deodorization, etc. Can be maintained for a long time, and when the medium contracts as the volatile substance is released, it can be peeled off from the container to change the internal state visible through the container. Changes, and it is possible to obtain a volatile substance emitter excellent in unexpectedness and decorativeness.

  When filling the concave formed in the concave holding medium with an independent holding medium made of a peelable transparent gelatin aqueous gel molded body that holds the volatile substance, the independent holding medium also shrinks and the shrinkage is filled into the concave. In this state, the shrinkage of the concave holding medium is peeled off, so that unexpectedness and decorativeness can be further enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a state before use of the volatile substance discharger according to the embodiment, (a) is a plan view in which a seal member and a ventilation member are partially removed, and (b) is an end view cut along the AA plane. 2 (a) and 2 (b) are end views taken along the plane AA of FIG. 1 (b) showing a state in use of the volatile substance discharger.

  In FIG. 1 and FIG. 2, the volatile substance discharger 1 has a depth in which the concave holding medium 2 is filled in a transparent container 3 and does not reach the inner wall 9 on the opposite side of the container 3 from the opening 11 side of the container 3. The recess 4 is formed in the holding medium 2, the opening 11 of the container 3 is sealed with a sealing member 12, and the ventilation member 13 is attached to the opening 11 of the container 3. The concave 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, filled in the container 3 without any gap from the opening 11 side, and is formed on the inner wall of the container 3. Although it has an intimate structure, there is a slight gap 6 between the outer surface 5 on the opening 11 side and the seal member 12.

  The container 3 is formed of a hard transparent plastic into a rounded pot shape, and the opening 11 has a smaller diameter than the maximum diameter part 7 of the container 3. The engaging portion 8 is formed. The concave portion 4 is formed of a cylindrical concave portion having a spherical tip, and has an opening 4 a having a smaller diameter than the opening 11 of the container 3, but may have the same diameter as the opening 11. 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 crosslinking agent and a volatile component is placed in the container 3 with the opening 11 on the top, and a mold (not shown) for forming the convex recess 4 corresponding to the recess 4 is provided on the opening 11 side. The reaction was carried out in the state of being inserted into the aqueous sol, so that the container 3 was filled without any gap from the opening 11 side and closely adhered to the inner wall of the container 3, and the recess 4 was formed on the opening 11 side. A concave holding medium 2 made of a shape-retaining transparent gelatin aqueous gel molded article having a jelly strength of 15 or more is formed.

  When the forming die is extracted from the opening 11 side after the reaction is completed, the concave portion 4 that does not reach the inner wall of the container 3 from the outer surface 5 of the holding medium 2 is exposed. 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, the seal member 12 of the container 3 is peeled off from the state of FIG. 1 and the container 3 is used with the opening 11 facing upward and covered with the ventilation member 13. FIGS. 2A and 2B show a state in use in which time has passed in that order.

  In the use state of the volatile substance discharger 1, the concave 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 is included in the holding medium 2. Volatile components such as fragrances and insect repellents are volatilized into the atmosphere from the outer surface 5 of the concave holding medium 2 and the surfaces of the concave portions 4, and function as a fragrance, insect repellent and the like. Since the concave holding medium 2 has a large surface shape due to the formation of the concave portion 4, the contact area with the atmosphere increases, and the volatile substance is efficiently volatilized and released into the atmosphere to impart aroma and deodorize. Etc. can be maintained for a long time.

  In addition, since the gelatin aqueous gel of the container 3 and the concave holding medium 2 is transparent, the light that strikes the volatile substance emitter 1 is reflected through the gel of the container 3 and the concave holding medium 2 through transmission, refraction, and emission. A beautiful aesthetic is obtained. Then, the shape change and the peeled state of the concave holding medium 2 accompanying the release of the volatile substance are observed through the container 3. That is, with the release of the volatile substance, the concave holding medium 2 starts to contract from the concave portion 4 and the outer surface 5 side. In this case, since the gelatin aqueous gel of the concave holding medium 2 is peelable, the concave holding medium 2 is in a state where it can be easily peeled from the container 3, and when the concave holding medium 2 starts to shrink, FIG. As shown in FIG. 2, the concave holding medium 2 is gradually peeled off from the opening 11 of the container 3.

  If the release of the volatile substance further continues, the concave holding medium 2 contracts in a similar manner, and the shrinkage of the concave holding medium 2 is completely peeled from the container 3 as shown in FIG. Separate in basket form. Since the container 3 has the opening 11 having a diameter smaller than that of the maximum diameter portion 7, the contracted material contracts toward the center in the opening 11, and the contracted material can be easily peeled off. The inner wall of the container 3 does not have a right-angled or acute-angled corner portion, and is formed of a continuous curved surface close to a sphere, and the opening 4a of the concave portion 4 has a diameter of 10 mm or more, so that the shrinkage can be easily peeled off. .

  Since the concave holding medium 2 is made of a peelable transparent gelatin aqueous gel molded body having a shape-retaining property, the concave holding medium 2 does not flow out of the opening 11 of the container 3 only by its own weight. Retained. In particular, when the opening 11 is filled in the container 3 having a diameter smaller than the maximum diameter portion 7 of the container 3, the holding property of the holding medium 2 when the opening 11 is used with the opening 11 as a bottom is further enhanced. 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.

  FIG. 3 shows a state before use of a volatile substance discharger according to another embodiment, (a) is a plan view in which a seal member and a ventilation member are partially removed, and (b) is cut along its BB plane.

  The volatile substance discharger 1 can prevent the concave holding medium 2 itself containing the volatile substance filled in the container 3 from flowing out, and volatile substances such as fragrances and deodorants contained in the holding medium 2. Can be efficiently volatilized and released into the atmosphere, and functions such as imparting fragrance and deodorization can be maintained for a long time. Moreover, the concave holding medium 2 and the independent holding medium 10 are similarly contracted and independently. In the state where the shrinkage of the holding medium 10 is filled in the concave portion 4, the shrinkage of the concave holding medium 2 is peeled off, and this is a volatile substance emitter excellent in unexpectedness and decoration.

5 (a) and 5 (b) are end views cut along a plane corresponding to AA in FIG. 1 (a), showing a state before use of the volatile substance discharger according to another embodiment.
The volatile substance emitter 1 shown in FIG. 5A is configured in substantially the same manner as that shown in FIGS. 1 and 2, but the concave portion 4 of the concave holding medium 2 has a conical shape having a spherical tip. Is different. The shape of the recess 4 is not limited to these, and may be other shapes. Although the use state of the volatile substance discharger 1 is not illustrated, it is substantially the same as that of FIG. 1 and FIG.

  The volatile substance discharger 1 of FIG. 5B is configured to be used in the inverted state, that is, with the opening 11 of the container 3 down. Although this volatile substance discharger 1 is configured in substantially the same manner as that of FIG. 5A, the opening 11 of the seal member 12 is provided with a filler holding member 18 such as a screen, and the concave holding medium 2 is provided. It is designed to support the shrinkage and filling material. The ventilation member 13 has a ventilation hole 17 formed on the side wall. The ability to fill the recess 4 of the concave holding medium 2 with the independent holding medium 10 and other fillers is the same as in the case of the volatile substance discharger 1 of other embodiments.

  The volatile substance emitter 1 shown in FIG. 5B is used with the seal member 12 peeled off in the state shown in FIG. Shrinkage and peeling of the concave holding medium 2 and the independent holding medium 10 are performed in the same manner as in the case of the volatile substance emitter 1 of other embodiments. Shrinkage and other fillings of the concave holding medium 2 and the independent holding medium 10 are supported by a filling holding member 18 such as a screen, and are prevented from falling downward.
