Description

本発明は、媒体が可剥性を有し、揮散性物質を徐々に放出するための揮散性物質放出器に関し、特に媒体の可剥性による経時的な美観の変化を伴い、装飾性に優れた揮散性物質放出器に関するものである。   The present invention relates to a volatile substance discharger for releasing a volatile substance gradually, with a medium having peelability, and in particular, with a change in aesthetics over time due to the peelability of the medium, and having excellent decorativeness. It relates to a volatilizer release device.

芳香剤、消臭剤、抗菌剤等の揮散性物質を含む液体または流動性ゲル状の保持媒体を容器内に収容し、容器を部分的に開口させて、液体または流動性ゲル状物に含まれる揮散性物質を徐々に放出するようにした揮散性物質放出器がトイレット用等に使用されている。   A liquid or fluid gel-like holding medium containing volatile substances such as fragrances, deodorants, antibacterial agents, etc. is contained in the container, and the container is partially opened to be contained in the liquid or fluid gel material. Volatile substance dischargers that gradually release volatile substances are used for toilets and the like.

図６は特許文献１に示された従来の揮散性物質放出器を示し、（ａ）は使用前、（ｂ）は使用中の状態を示す断面図である。
図６において、揮散性物質放出器１は、揮散性物質を含む液体または流動性ゲル状の保持媒体２を収容する容器３と、容器３の開口部１１を密封するシール部材１２と、容器３の開口部１１を下にした状態で支持する通気部材１３と、容器３の開口部１１から流出する保持媒体２を受けて貯留し、揮散性物質を大気中に揮散させて放出する貯留揮散部１４とを備えている。 6A and 6B show a conventional volatile substance emitter shown in Patent Document 1, wherein FIG. 6A is a cross-sectional view showing a state before use, and FIG.
In FIG. 6, a volatile substance discharger 1 includes a container 3 that contains a liquid or fluid gel-like holding medium 2 containing a volatile substance, a seal member 12 that seals the opening 11 of the container 3, and a container 3. The storage member volatilizing part 13 which receives and stores the ventilation member 13 supported in a state where the opening part 11 is down, and the holding medium 2 flowing out from the opening part 11 of the container 3 and volatilizes and releases the volatile substance into the atmosphere. 14.

シール部材１２は、外部から引き剥がし可能な引張り部１２ａを有する。通気部材１３は貯留揮散部１４から上に伸びるように一体化し、その上端部は容器３の受部１５と係合して容器３を支持している。貯留揮散部１４は、保持媒体を貯留する貯留部１６の上方に、揮散性物質を揮散させる通気孔１７を有する。容器３は首部３ａに開口部１１が形成されており、その開口部１１は貯留揮散部１４の貯留部１６の上縁より下に開口している。シール部材１２の引張り部１２ａは通気孔１７を通して外部に伸びている。   The seal member 12 has a pulling portion 12a that can be peeled off from the outside. The ventilation member 13 is integrated so as to extend upward from the storage volatilization part 14, and the upper end part thereof is engaged with the receiving part 15 of the container 3 to support the container 3. The storage volatilization part 14 has the ventilation hole 17 which volatilizes a volatile substance above the storage part 16 which stores a holding | maintenance medium. An opening 11 is formed in the neck 3 a of the container 3, and the opening 11 opens below the upper edge of the storage part 16 of the storage volatilization part 14. The tension portion 12 a of the seal member 12 extends to the outside through the vent hole 17.

上記の揮散性物質放出器１は、使用前の状態では、揮散性物質を含む液体または流動性ゲル状の保持媒体２を収容する容器３が、開口部１１をシール部材１２で密封されている。容器３は使用前の状態では、開口部１１を上向きにしていてもよいが、開口部１１を下にした状態で通気部材に支持され、この状態でシール部材１２は通気孔１７を通して外部に伸び、外部から引き剥がし可能とされている。   In the volatile substance discharger 1, in a state before use, a container 3 containing a liquid containing a volatile substance or a fluid gel-like holding medium 2 is sealed with an opening 11 by a seal member 12. . In a state before use, the container 3 may have the opening 11 facing upward, but is supported by the ventilation member with the opening 11 facing downward, and in this state, the seal member 12 extends to the outside through the ventilation hole 17. It can be peeled off from the outside.

上記の揮散性物質放出器を使用する場合は、容器３の開口部１１を下にして通気部材１３に支持した状態でシール部材１２を引き剥がすことにより、容器３の開口部１１から流出する保持媒体２を貯留揮散部１４に受けて貯留し、揮散性物質を貯留揮散部１４の通気孔１７から大気中に揮散させて放出し、芳香の付与、消臭等を行う。容器３の開口部１１が貯留揮散部１４の貯留部１６の上縁より下に開口していると、容器３内の保持媒体２の流出は停止し、貯留揮散部１４に貯留される保持媒体２の液面は一定に維持される。   When using the above volatile substance discharger, the seal member 12 is peeled off in a state of being supported by the ventilation member 13 with the opening 11 of the container 3 facing down, thereby holding out the opening 11 of the container 3. The medium 2 is received and stored in the storage and volatilization unit 14, and the volatile material is volatilized and released from the vent 17 of the storage and volatilization unit 14 into the atmosphere to give aroma and deodorize. When the opening 11 of the container 3 opens below the upper edge of the storage part 16 of the storage volatilization part 14, the outflow of the holding medium 2 in the container 3 stops and the storage medium stored in the storage volatilization part 14 The liquid level of 2 is kept constant.

しかしながら、このような従来の揮散性物質放出器１においては、揮散性物質を含む保持媒体２は液体または流動性ゲル状であるため、放出器１が転倒した場合には、貯留部揮散部１４に貯留される保持媒体２は通気孔１７から流出するおそれがある。また容器３および貯留部１６内には、保持媒体２が充填されているだけであるため、容器３および貯留揮散部１４を透明にしても、装飾性は必ずしも高いとはいえない。
特開２００４−２９０２１６号 However, in such a conventional volatile substance discharger 1, since the holding medium 2 containing the volatile substance is liquid or fluid gel, when the discharger 1 falls down, the storage part volatile part 14 The retaining medium 2 stored in the air may flow out of the vent hole 17. Moreover, since the container 3 and the storage part 16 are only filled with the holding medium 2, even if the container 3 and the storage volatilization part 14 are made transparent, the decorativeness is not necessarily high.

本発明において、揮散性物質を保持する保持媒体を充填する容器は、最大径部より小径の開口部を有する透明な容器であり、硬質透明プラスチック、ガラス等の形状保持性を有する透明材料から、開口部を有する容器状に形成される。透明材料は、外部から透視できる程度の透明性を有し、無色または着色透明のいずれでもよい。容器は開口部側またはその反対側を底部として、自立できる構造のものが好ましい。容器の内壁は、直角または鋭角状のコーナー部を持たないもの好ましく、特に連続する曲面、または曲面と平面とが連続する面からなるものが好ましい。内壁に直角または鋭角状のコーナー部が形成されると、保持媒体が剥離しにくくなるが、直角より大きい鈍角状のコーナー部であれば、剥離は容易になる。   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.

容器は、開口部の反対側の内壁から最大径部に向かって次第に大径になり、最大径部から開口部に向かって次第に小径になるように構成されているのが好ましく、これにより媒体の剥離が容易になるとともに、開口部側を底部として自立させて使用する際の、保持媒体の保持性を高めることができる。容器の正面から見た正面形状（垂直断面形状）、ならびに開口部側から見た平面形状（水平断面形状）は、それぞれ直角または鋭角部を持たない連続する線状のものが好ましく、特に円形、楕円形、長円形、卵形、またはこれらに類似した滑らかな形状が好ましい。   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.

本発明において、保持媒体に保持される揮散性物質は、保持媒体から揮散により大気中に放出される物質であり、揮散性の芳香剤、香料、消臭剤、防虫成分、薬剤成分などが挙げられる。これらの揮発成分は、水溶性でも油溶性でもよいが、保持媒体であるゼラチン水性ゲル中に均一に溶解ないし分散して透明なゲル成形体を形成し、容易にゲルの表面に浸透して揮散するものが好ましい。   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.

このような揮散性物質を保持する凹状保持媒体および／または独立保持媒体は、それぞれ可剥性透明ゼラチン水性ゲル成形体からなるが、特に凹状保持媒体は、揮散性物質の放出に伴って媒体が収縮するとき容器から剥離する可剥性および形状保持性を有する透明ゼラチン水性ゲル成形体から形成する。保持媒体としての可剥性透明ゼラチン水性ゲル成形体は、形状保持性および可剥性を有する架橋した透明架橋ゼラチン水性ゲル成形体が好ましく、特にゼラチン、架橋剤および揮発成分を含む水性ゾルの反応物であって、ゼリー強度１５以上の透明ゼラチン水性ゲル成形体が好ましい。このようなゼラチン水性ゲル成形体は、水分が分離せず、形状保持性に優れ、大表面形状に形成しても、形状を保持することが可能である。 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.

このような揮散性物質を保持する可剥性透明ゼラチン水性ゲル成形体からなる凹状保持媒体は、揮散性物質の放出に伴って媒体が収縮するとき容器から剥離するもので、透明な容器に開口部側から隙間なく充填されて、容器の内壁に密着した構造を有するが、開口部側には隙間が生じていてもよい。このように充填された凹状保持媒体には、容器の開口部側から容器の反対側の内壁に至らない深さで、凹部形成用の成形型により凹部が形成され、これにより大表面形状に形成され、大気との接触面積が大きくなる。凹部は、容器の開口部と同一または小径の開口部を有するものが好ましい。凹部の開口部は、周辺部のゼラチン水性ゲルが、揮散性物質の放出に伴い開口部の中央側に収縮して容器から剥離できる程度の大きさであればよく、容器および凹部の形状、寸法等によって異なるが、一般的には１０ｍｍ以上の径を有する。 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.

凹部および容器の開口部の形状は、ゼラチン水性ゲルが、揮散性物質の放出に伴い開口部の中央側に収縮しやすい形状とするのが好ましく、凹部の水平断面および開口部の形状は、円形、楕円形、長円形、卵形、またはこれらに類似した滑らかな形状が好ましいが、角形その他の形状でもよい。容器の開口部における容器の内壁から凹部の開口部に至る凹状保持媒体の上面の厚みは、容器および凹部の形状、寸法等によって異なるが、一般的には５０ｍｍ以下とするのが好ましい。   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.

このような凹状保持媒体の凹部は、内部に充填物を充填してもよく、また何も充填しないで、空の状態としてもよい。充填物としては、制限はなく、花、人形、動物等のマスコットなど、任意のものがある。充填物として、凹状保持媒体と同種の、または異種の可剥性透明ゼラチン水性ゲル成形体からなる独立保持媒体を充填することができ、この場合、揮散性物質を保持する可剥性透明ゼラチン水性ゲル成形体からなる独立保持媒体を充填すると、揮散性物質の保持量が多くなり、その放出量も多くなるので好ましい。凹状保持媒体および独立保持媒体を、それぞれ可剥性透明ゼラチン水性ゲル成形体で形成すると、それぞれが分離した状態で収縮し、独立保持媒体の収縮物が凹状保持媒体の収縮物内に収容される。   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. .

上記の凹状保持媒体は、ゼラチン、架橋剤および揮発成分を含む水性ゾルを透明な容器に入れ、水性ゾル中に凹部形成用の成形型を開口部側から挿入した状態で反応させることにより、透明な容器に開口部側から隙間なく充填されて、容器の内壁に密着した構造を有し、開口部側に凹部が形成されたゼリー強度１５以上の形状保持性を有する可剥性透明架橋ゼラチン水性ゲル成形体が形成される。反応終了後、成形型を開口部側から抜き取ることにより、凹状保持媒体が形成される。独立保持媒体は、別途凹状の成形型を用いて、同様にして形成される。凹状保持媒体の凹部に独立保持媒体または他の充填物を充填し、あるいは充填することなく、容器の開口部をシール部材で密封することにより、揮散性物質放出器が得られる。通気部材を備える場合は、通気孔を有し、容器の開口部を下にした状態で支持する通気部材、または容器の開口部を上にした状態で容器の開口部を覆う通気部材を、容器の開口部に取り付けた状態で製品としてもよく、また取り付けない状態で製品としてもよい。   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.

本発明で用いる可剥性ゼラチン水性ゲルは、分子量１００，０００以上、５００，０００未満の高分子量ゼラチン１．５〜５重量％、好ましくは２〜４重量％、分子量３，０００以上、１０，０００未満の低分子量ゼラチン０．０５〜０．５重量％、好ましくは０．１〜０．４重量％、架橋剤０．１〜１重量％、好ましくは０．４〜０．８重量％、および揮発成分０．５〜１０重量％、好ましくは１〜８重量％を含む水性ゾルの反応物からなるゼラチン水性ゲルが好ましい。上記の水性ゾルは、分子量１０，０００以上、１００，０００未満の中分子量ゼラチン０．１〜５重量％、好ましくは０．２〜４重量％を含むものが好ましい。   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.

ゼラチンはニカワとして接着剤に用いられることから分かるように、接着性に優れるため、複雑な形状に成形すると、成形型の離型、および保持媒体の収縮に伴う剥離が困難であるが、さらに分子量３，０００以上、１０，０００未満の低分子量ゼラチンを含むゼラチン混合物を用いると、離型性、可剥性がよくなる。このため複雑な形状の凹部形成用の成形型を用いる場合でも、ゲル成形体を傷つけることなく容易に型抜きを行うことができ、複雑な形状の凹部を形成することができるとともに、保持媒体の収縮に伴う剥離が可能となる。このゲル成形体を、容器の開口部を下にした状態で使用する場合でも、ゲル成形体の自重だけではゲル成形体が開口部から流出することはなく、容器内に保持することができ、特に開口部が容器の最大径部より小径とされているのが好ましく、これにより開口部側を底部として自立させて使用したときに、保持媒体の保持性を高めることができる。   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.

ゼラチンの分子量は、変性の条件、例えば変性に用いる薬剤および助剤の種類、濃度、温度、時間等により変わるので、変性の条件を選ぶことにより、目的とする分子量のゼラチンを得ることができる。ゼラチンの平均分子量は、パギイ法第９版（２００２）により分子量分布を測定して求めることができる。また形状保持性の指標となるゲルの強度は、ＪＩＳ Ｋ ６５０３のゼリー強度として測定することができる。   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.

架橋剤としては、ゼラチンの官能基と反応して架橋できるものであればよいが、エチレン性不飽和化合物−無水マレイン酸共重合体、その開環重合体またはその塩が好ましい。エチレン性不飽和化合物としては、エチレン、プロピレン、ブテン−１，ブテン−２、イソブチレン等のオレフィン類、その他のエチレン性不飽和基を有する化合物が挙げられる。開環重合体はエチレン性不飽和化合物−無水マレイン酸共重合体に加水して開環した重合体、その塩は開環重合体のアンモニウム塩、ナトリウム塩等の塩である。塩は上記酸共重合体または開環重合体と水酸化アンモニウム、または水酸化ナトリウム塩等を反応させて形成することができる。   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.

エチレン性不飽和化合物−無水マレイン酸共重合体はこれらのエチレン性不飽和化合物と無水マレイン酸との共重合体であり、エチレン性不飽和化合物と無水マレイン酸とのモル比は１０：１〜１：１０、好ましくは５：１〜１：５、平均分子量は、通常２，０００〜５，０００，０００であり、好ましくは３，０００〜３，０００，０００である。このようなエチレン性不飽和化合物−無水マレイン酸共重合体としては市販品が用いられる。その開環重合体、アンモニウム塩、ナトリウム塩等の塩における開環または塩に変換する割合は任意であるが、無水環の全部を変換するのが好ましい。   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.

上記の可剥性ゼラチン水性ゲルは、これらのゼラチン、架橋剤および揮発成分を含む水性ゾルの反応物であって、ゼラチンと架橋剤とは揮発成分、水性溶媒、および必要により加えられる他の成分を抱き込むように反応して架橋し、水性ゲルを形成した反応物からなる可剥性透明架橋ゼラチン水性ゲル成形体である。このような可剥性ゼラチン水性ゲルは、上記水性ゾルを２０〜７０℃、好ましくは室温〜６０℃で反応させることにより、製造することができる。こうして形成される可剥性ゼラチン水性ゲルは、揮発成分、水性溶媒、および必要により加えられる他の成分を抱き込んだ状態でゼラチンが架橋した水性ゲルであり、ゲル形成剤の濃度が低い場合でも、形状保持性に優れる成形体を形成することができる。   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.

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.

本発明の揮散性物質放出器は、使用前の状態では、揮散性物質を含む可剥性ゲル状の保持媒体を収容する容器が、開口部をシール部材で密封されている。容器は使用前の状態では、開口部を上にした状態でも、開口部を下にした状態でもよい。通気部材を備える場合は、通気部材は容器の開口部に取り付けた状態でも、取り付けない状態でもよく、任意の状態で製品とすることができる。揮散性物質放出器を使用する場合は、容器の開口部を上にした状態で使用する方が、凹状保持媒体の収縮物がバスケット状で剥離するため、また充填物を凹部に充填した場合は、充填物が凹部に充填された状態で、凹状保持媒体の収縮物が剥離するため、意外性、装飾性が高いが、容器の開口部を下にした状態で使用することもできるようにしてもよい。容器の開口部を下にした状態で使用する場合には、充填物が落下しないように、シール部材の位置、またはその付近に、スクリーン等の充填物保持部材を設ける。 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.

上記の揮散性物質放出器を使用する場合は、容器からシール部材を引き剥がし、容器の開口部を上にした状態、または容器の開口部を下にした状態で使用する。通気部材を備える場合は、容器からシール部材を引き剥がし、容器の開口部を上にして通気部材で容器の開口部を覆った状態、または容器の開口部を下にして通気部材に支持した状態で使用する。   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.

このとき容器内の保持媒体は、容器の開口部および通気部材の通気孔を通して大気と接触することになり、保持媒体に含まれる香料、防虫成分等の揮発成分はゲルの表面から大気中に揮散し、芳香剤、防虫剤などとしての機能を発揮する。凹状保持媒体には、容器の開口部側から容器内壁に至らない深さで凹部が形成されて大表面形状となっているため、大気との接触面積が大きくなり、揮散性物質を効率よく揮散させて大気中に放出させ、芳香の付与、消臭等の機能を長く維持することができる。また独立保持媒体を充填する場合は、独立保持媒体は独立状態で形成されているため、大気との接触面積をさらに大きくして、揮散性物質の揮散効率をさらに高くすることができる。   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.

また容器および保持媒体のゼラチン水性ゲルは透明であるため、揮散性物質放出器に当たる光線は、容器およびゲルを透過、屈折、放出に伴う反射するため、優れた美観が得られる。そして揮散性物質の放出に伴う保持媒体の形状変化、剥離状態が容器を通して観察される。すなわち揮散性物質の放出に伴って、凹状保持媒体は相似的に収縮し、その収縮物が少しずつ剥離し、最終的に完全にバスケット状で剥離する。最大径部より小径の開口部を有する容器を用いることにより、収縮物が開口部の中央側に収縮するため、収縮物の剥離が容易になる。容器の内壁が、直角または鋭角状のコーナー部を持たないもの、特に連続する曲面、または曲面と平面とが連続する面からなるもの、例えば容器の垂直断面形状および水平断面形状がそれぞれ直角または鋭角部を持たない連続する線状のもの、特に円形、楕円形、長円形、卵形、またはこれらに類似した滑らかな形状のもの、ならびに凹部の開口部が１０ｍｍ以上の径を有する場合なども、収縮物の剥離が容易になる。   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.

凹状保持媒体の凹部に充填物を充填した場合は、充填物が凹部に充填された状態で、凹状保持媒体の収縮物が剥離する。充填物が独立保持媒体である場合は、独立保持媒体も収縮し、収縮物が凹部に充填された状態で、凹状保持媒体の収縮物が剥離する。このような保持媒体の形状変化、剥離状態は、容器を通して外部から観察され、意外性、装飾性が高い揮散性物質放出器が得られる。容器の開口部を下にした状態で使用する場合には、シール部材の位置、またはその付近に、スクリーン等の充填物保持部材を設け、充填物を充填物保持部材で支持することができる。   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.

上記の保持媒体は形状保持性を有するため、ゲル成形体の自重だけではゲル成形体が容器の開口部から流出することはなく、容器内に保持して揮散性物質を放出することができる。また開口部が容器の最大径部より小径の容器に充填されているため、開口部側を底部として自立させて使用するばあいでも、保持媒体の保持性は高い。また保持媒体は形状保持性が高いので、長期にわたって成形体の形状を保持することができ、揮発成分が揮散して体積が減少しても、形状が崩れることなく、ほぼ元の形状を保持したまま、相似形に体積が減少して剥離し、美観を損なうことがない。   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.

本発明の揮散性物質放出器によれば、最大径部より小径の開口部を有する透明な容器に、揮散性物質を保持し、揮散性物質の放出に伴って媒体が収縮するとき容器から剥離する可剥性および形状保持性を有する透明ゼラチン水性ゲル成形体からなる凹状保持媒体を充填し、開口部側から容器の反対側の内壁に至らない深さの開口部が１０ｍｍ以上の径を有し、かつ揮散性物質の放出に伴って媒体が中央側に収縮する形状を有する凹部を凹部形成用の成形型により保持媒体に形成し、シール部材を剥がして、揮散性物質を揮散させるようにしたため、容器内に充填された揮散性物質を含む保持媒体自体の流出を防止した状態で、保持媒体に含まれる芳香剤、消臭剤等の揮散性物質を効率よく揮散させて大気中に放出させ、芳香の付与、消臭等の機能を長く維持することができ、しかも揮散性物質の放出に伴って媒体が収縮するとき容器から剥離させて、容器を通して視認される内部の状態を変化させることができ、これにより経時的に美観が変化し、意外性、装飾性に優れた揮散性物質放出器を得ることができる。 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.

凹状保持媒体に形成された凹部に、揮散性物質を保持する可剥性透明ゼラチン水性ゲル成形体からなる独立保持媒体を充填する場合は、独立保持媒体も収縮し、収縮物が凹部に充填された状態で、凹状保持媒体の収縮物が剥離するので、意外性、装飾性をさらに高めることができる。   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.

以下、本発明の実施の形態を図面により説明する。図１は実施形態による揮散性物質放出器の使用前の状態を示し、（ａ）はシール部材および通気部材を一部取り去った平面図、（ｂ）はそのＡ−Ａ面で切断した端面図、図２（ａ）、（ｂ）はそれぞれ揮散性物質放出器の使用中の状態を示す図１（ｂ）のＡ−Ａ面で切断した端面図である。   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.

図１および図２において、揮散性物質放出器１は、凹状保持媒体２が透明な容器３に内に充填され、容器３の開口部１１側から容器３の反対側の内壁９に至らない深さで凹部４が保持媒体２に形成されており、容器３の開口部１１はシール部材１２で密封され、通気部材１３が容器３の開口部１１に取り付けられている。凹状保持媒体２は、揮散性物質を保持する形状保持性を有する可剥性透明架橋ゼラチン水性ゲル成形体からなり、容器３に開口部１１側のから隙間なく充填されて、容器３の内壁に密着した構造を有するが、開口部１１側の外表面５とシール部材１２との間に若干の隙間６が生じている。   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.

容器３は、硬質透明プラスチックにより、球形に近い丸みを帯びたポット状に形成され、開口部１１が容器３の最大径部７より小径とされ、開口部１１の外周部には通気部材１３との係合部８が形成されている。凹部４は、先端が球面となった円筒状の凹部からなり、容器３の開口部１１より小径の開口部４ａを有するが、開口部１１と同径であってもよい。シール部材１２は、開口部１１に剥離可能に固着されている。通気部材１３は、周壁に通気孔１７を有し、容器３の開口部１１を覆うように、取り外し可能に取り付けられている。   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.

上記の揮散性物質放出器１は、以下のようにして製造される。まず開口部１１を上にした容器３に、ゼラチン、架橋剤および揮発成分を含む水性ゾルを入れ、凹部４に対応した凸形状の凹部４形成用の成形型（図示省略）を開口部１１側から水性ゾル中に挿入した状態で反応させることにより、容器３に開口部１１側から隙間なく充填されて容器３の内壁に密着した構造を有し、開口部１１側に凹部４が形成されたゼリー強度１５以上の形状保持性透明ゼラチン水性ゲル成形体からなる凹状保持媒体２を形成する。   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.

反応終了後、成形型を開口部１１側から抜き取ると、保持媒体２の外表面５から容器３の内壁に至らない凹部４が露出する。この状態で容器３の開口部１１をシール部材１２で密封し、通気部材１３と組み合わせることにより、揮散性物質放出器１が製造される。揮散性物質放出器１は、開口部１１を上にした状態で、製品として運搬、保管するが、逆でもよい。通気部材１３は、容器３の開口部１１に取り付けた状態で製品としてもよく、また取り付けない状態で製品としてもよい。   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.

上記の揮散性物質放出器１は、図１、２に示すように開口部１１を上にして通気部材１３で覆った状態で使用する。すなわち図１の状態から、容器３のシール部材１２を引き剥がし、容器３の開口部１１を上にして通気部材１３で覆った状態で使用する。図２（ａ）、（ｂ）は、その順序で時間が経過した使用中の状態を示す。   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.

揮散性物質放出器１の使用状態では、容器３内の凹状保持媒体２は、容器３の開口部１１および通気部材１３の通気孔１７を通して大気と接触することになり、保持媒体２に含まれる香料、防虫成分等の揮発成分は、凹状保持媒体２の外表面５および凹部４の表面から大気中に揮散し、芳香剤、防虫剤などとしての機能を発揮する。凹状保持媒体２は、凹部４の形成により大表面形状となっているため、大気との接触面積が大きくなり、揮散性物質を効率よく揮散させて大気中に放出させ、芳香の付与、消臭等の機能を長く維持することができる。   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.

また容器３および凹状保持媒体２のゼラチン水性ゲルは透明であるため、揮散性物質放出器１に当たる光線は、容器３および凹状保持媒体２のゲルを透過、屈折、放出に伴う反射するため、優れた美観が得られる。そして揮散性物質の放出に伴う凹状保持媒体２の形状変化、剥離状態が容器３を通して観察される。すなわち揮散性物質の放出に伴って、凹状保持媒体２は凹部４および外表面５側から収縮を始める。この場合、凹状保持媒体２のゼラチン水性ゲルは可剥性であるため、凹状保持媒体２は容器３から容易に剥離できる状態にあり、凹状保持媒体２が収縮を始めると、図２（ａ）に示すように、凹状保持媒体２は容器３の開口部１１から少しずつ剥離していく。   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.

さらに揮散性物質の放出が続くと、凹状保持媒体２が相似的に収縮し、図２（ｂ）に示すように、凹状保持媒体２の収縮物が容器３から完全に剥離し、最終的にバスケット状で分離する。容器３は最大径部７より小径の開口部１１を有するため、収縮物が開口部１１では中央側に収縮し、収縮物の剥離が容易になる。容器３の内壁は、直角または鋭角状のコーナー部を持たず、球形に近い連続する曲面からなり、凹部４の開口部４ａが１０ｍｍ以上の径を有することにより、収縮物の剥離は容易である。   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. .

上記の凹状保持媒体２は、形状保持性を有する可剥性透明ゼラチン水性ゲル成形体からなるため、凹状保持媒体２の自重だけで容器３の開口部１１から流出することはなく、容器３内に保持される。特に開口部１１が容器３の最大径部７より小径の容器３に充填することにより、開口部１１側を底部として自立させて使用する際の保持媒体２の保持性はさらに高くなる。また保持媒体２は形状保持性が高いので、長期にわたって成形体の形状を保持することができ、揮発成分が揮散して体積が減少しても、形状が崩れることなく、ほぼ元の形状を保持したまま、相似形に体積が減少し、美観を損なうことがない。   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.

図３は他の実施形態による揮散性物質放出器の使用前の状態を示し、（ａ）はシール部材および通気部材を一部取り去った平面図、（ｂ）はそのＢ−Ｂ面で切断した端面図、図４（ａ）、（ｂ）はそれぞれ揮散性物質放出器の使用中の状態を示す図３（ｂ）のＢ−Ｂ面で切断した端面図である。   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. End views, FIGS. 4 (a) and 4 (b), are end views taken along the plane B-B in FIG. 3 (b), showing a state in use of the volatile substance discharger.

図３および図４において、揮散性物質放出器１は、図１および図２のものとほぼ同様に構成されているが、凹状保持媒体２の凹部４内に、可剥性透明ゼラチン水性ゲル成形体で別途形成した球状の独立保持媒体１０を充填している点で相違している。独立保持媒体１０は可剥性透明ゼラチン水性ゲル成形体からなるため、複数個が相互に接着せず、また凹状保持媒体２とも接着することなく、充填状態を保ち、使用される。この実施形態では、充填物として、可剥性透明ゼラチン水性ゲル成形体からなる独立保持媒体１０を充填しているが、可剥性透明ゼラチン水性ゲル成形体以外の充填物であってもよく、また可剥性透明ゼラチン水性ゲル成形体の場合でも、他の形状、構造のものでもよい。   3 and 4, the volatile substance discharger 1 is configured in substantially the same manner as that of FIGS. 1 and 2, but a peelable transparent gelatin aqueous gel is formed in the recess 4 of the concave holding medium 2. The difference is that a spherical independent holding medium 10 separately formed by a body is filled. Since the independent holding medium 10 is made of a peelable transparent gelatin aqueous gel molded product, a plurality of independent holding media 10 are not adhered to each other and are not adhered to the concave holding medium 2, and are used in a filled state. In this embodiment, the filler is filled with the independent holding medium 10 made of a peelable transparent gelatin aqueous gel molded body, but may be a filler other than the peelable transparent gelatin aqueous gel molded body, Further, even in the case of a peelable transparent gelatin aqueous gel molded body, it may have other shapes and structures.

揮散性物質放出器１の使用状態は、図４（ａ）、（ｂ）に示すように、図１および図２のものとほぼ同様であるが、凹状保持媒体２の凹部４内に、可剥性透明ゼラチン水性ゲル成形体で別途形成した球状の独立保持媒体１０を充填しているため、大気との接触面積がさらに大きくなり、揮散性物質の揮散効率がさらに高くなる。そして揮散性物質の放出に伴って、充填物としての独立保持媒体１０が凹部４に充填された状態で、凹状保持媒体２の収縮物が剥離する。このとき充填物が独立保持媒体１０であるため、独立保持媒体１０も同様に相似的に収縮し、収縮物が凹部４に充填された状態で、凹状保持媒体２の収縮物が剥離する。このような凹状保持媒体２および独立保持媒体１０の形状変化、剥離状態などは、容器３を通して外部から観察され、意外性、装飾性がさらに高い揮散性物質放出器１が得られる。   As shown in FIGS. 4 (a) and 4 (b), the use state of the volatile substance discharger 1 is substantially the same as that in FIGS. Since the spherical independent holding medium 10 separately formed with the peelable transparent gelatin aqueous gel molded body is filled, the contact area with the atmosphere is further increased, and the volatilization efficiency of the volatile material is further increased. And with discharge | emission of a volatile substance, the shrinkage | contraction material of the concave holding medium 2 peels in the state by which the independent holding medium 10 as a filling was filled in the recessed part 4. FIG. At this time, since the filling material is the independent holding medium 10, the independent holding medium 10 similarly shrinks in a similar manner, and the shrinkage of the concave holding medium 2 is peeled in a state where the shrinkage is filled in the recess 4. Such a shape change, a peeled state, and the like of the concave holding medium 2 and the independent holding medium 10 are observed from the outside through the container 3, and the volatile substance discharger 1 having higher unexpectedness and decorativeness can be obtained.

上記の揮散性物質放出器１は、容器３内に充填された揮散性物質を含む凹状保持媒体２自体の流出を防止でき、保持媒体２に含まれる芳香剤、消臭剤等の揮散性物質を効率よく揮散させて大気中に放出させ、芳香の付与、消臭等の機能を長く維持することができ、しかも凹状保持媒体２および独立保持媒体１０が同じように相似的に収縮し、独立保持媒体１０の収縮物が凹部４に充填された状態で、凹状保持媒体２の収縮物が剥離し、意外性、装飾性に優れた揮散性物質放出器である。   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.
