Description

【０００１】
【発明の属する技術分野】
本発明は、燻煙殺虫剤、消臭剤、芳香剤などの薬剤を水との反応で蒸散させる蒸散器に関する。
【０００２】
【従来の技術】
この種の蒸散器として、耐熱性の内容器の中に燻煙殺虫剤と、生石灰よりなる発熱剤とを上下に収容し、この内容器を外容器の中に収容した加熱蒸散殺虫器がある。これの使用時には、外容器から内容器を取り出し、外容器の中に所定量の水を入れてから、内容器を外容器の中に入れ直す。すると、発熱剤が内容器の底に設けた通水孔から浸入する水と反応して発熱し、この熱で燻煙殺虫剤が蒸散して内容器の上面に設けた蒸散口から放出するものになっている。また、同様の形態で燻煙殺虫剤を芳香剤や消臭剤などに代えて、これらを蒸散させる場合にも、類似の問題があった。
【０００３】
【発明が解決しようとする課題】
しかし、使用時に外容器の中へ水を入れるに際し、一般に水道水を小さいカップに入れて外容器の中に該容器の内面に印された一定水量を示すマーク位置に達するまで流し込んでいる。こうした給水の仕方では小さいカップを用いる必要があるなど甚だ煩わしい手間を要する。また水を入れ過ぎたり、不足したりすることがあり、これが原因して燻煙殺虫剤が充分に蒸散しないことがある。
【０００４】
そこで本発明の目的は、使用者が外容器に水を入れる手間を省略できる蒸散器を提供することにある。
【０００５】
【課題を解決するための手段】
本発明の加熱蒸散殺虫器は、図１に示すごとく上面が開口する外容器１と、外容器１内にそれぞれ出し入れ可能に収容される内容器４および給水容器５とを備えている。内容器４は、底面に通水孔２６を、上面側に蒸散口２７をそれぞれ有する。内容器４の内部には、通水孔２６を介して流入する水と反応して蒸散する薬剤が収納されている。給水容器５は、図１に示すごとくこれの下面に給水口１５を有し、この給水口１５が破断容易なシール材１６で閉じられている。外容器１内の一部にこれの下面から筒壁１０を立設することにより、外容器１の内部が、図２に示すごとく給水容器５を上下動自在に収容する筒壁１０内の第２収容室１２と、内容器４を出し入れ自在に収容する筒壁１０外の第１収容室１１とに区画形成されている。筒壁１０には、これの開口上端縁から下向きに縦溝１３と、該縦溝１３よりも浅い受け溝１９とをそれぞれ異なる部位に設けてある。給水容器５の筒壁の外周一部には、下向きの受け面２２ａを有する突部２２が設けられている。外容器１における第２収容室１２の下面には、突起１７を設けてある。筒壁１０の受け溝１９の下端で給水容器５の突部２２の受け面２２ａを受け止めることにより、第２収容室１２に給水容器５をこれの上端部が筒壁１０の上方に露出する浮き上がり状態で支持することができる。一方、筒壁１０の縦溝１３に給水容器５の突部２２を嵌合することにより、図４に示すごとく第２収容室１２内において給水容器５をこれのシール材１６が突起１７で突き破られるように押し下げることができる。そのうえで、外容器１の内部に、シール材１６が破られて給水容器５から流出した水を内容器４の通水孔２６へ導くための水路１４が設けられている。
【０００６】
燻煙殺虫器として用いるときは、前記内容器４に、燻煙殺虫剤２を収納するとともに、内容器４の内底面と燻煙殺虫剤２との間に、水と反応して燻煙殺虫剤２を加熱蒸散させる発熱剤３が収納されたものとすることができる。
【０００７】
また、給水容器５には、これの筒壁の上端から下向きに延びる縦長リブ状の突部２２を複数箇所に形成してあり、各突部２２の下端の受け面２２ａが給水容器５の上下方向の中間に位置している。この突部２２に対応して筒壁１０には、縦溝１３と受け溝１９とが複数箇所に設けられている。受け溝１９は、筒壁１０の上端から上下中間高さ位置に到る垂直状の止め壁面２０と、これの下端から筒壁１０の上端縁に到る傾斜案内壁面２１とを有し、給水容器５を右または左に回すと、突部２２の受け面２２ａが傾斜案内壁面２１を滑り上がるようにしてある。
【０００８】
【作用】
輸送時、すなわちユーザーの手元に渡るまでの間は、第２収容室１２に給水容器５をこれの給水口１５が下向きの状態で収容し、図１および図３に示すごとく突部２２の受け面２２ａを受け溝１９の下端で受け止める。このとき、給水容器５の上端部は筒壁１０の上方に手づかみ可能に露出しており、給水口１５のシール材１６が突起１７上に離れて位置する浮き上がり姿勢に支持されている。
【０００９】
使用時には、外容器１内の第２収容室１２にある給水容器５の上端部を手でつかんで右または左（図示側では右）に回すと、突部２２の受け面２２ａが傾斜案内壁面２１の下端から該壁面２１に沿って滑り上がって行く。次に、図４に示すごとく突部２２を縦溝１３に位置合わせして給水容器５を第２収容室１２内に再び挿入し直し、給水容器５を手で押し込むと、シール材１６が突起１７で突き破られ、給水容器５内の水が給水口１５から外部に流れ出る。この流出水は外容器１内で水路１４を通って内容器４の通水孔２６へ導かれ、内容器４の薬剤が通水孔２６を介して流入の水と反応して蒸散する。具体的には、発熱剤３が流入水と反応し、燻煙殺虫剤２が発熱剤３で加熱されて蒸気となり蒸散口２７から発散する。
【００１０】
【発明の実施の形態】
（第１実施例）図１ないし図４は本発明に係る蒸散器の第１実施例として加熱蒸散殺虫器を示しており、外容器１の中に、燻煙殺虫剤２および発熱剤３を収容した内容器４と、給水容器５とがそれぞれ上方から出し入れ可能に収納されている。
【００１１】
外容器１は、図２および図３に示すごとく上面が開口するプラスチック製の有底筒状の容器本体６と、この容器本体６の開口上面を閉じるためにこれの上端口部７に着脱可能に装着されるプラスチック製の蓋９とからなる。蓋９は中央開口９ａを有する環状に形成してある。容器本体６内の一部、図では右側にこれの下面から円形の筒壁１０を一体に立設することにより、内容器４が上方から出し入れできる筒壁１０外の第１収容室１１と、給水容器５が上方から上下動自在に収納される筒壁１０内の第２収容室１２とが左右に区画形成されている。筒壁１０には、左右のほぼ対向位置に縦溝１３・１３を設けてあり、左側の縦溝１３の下端で第２収容室１２と第１収容室１１との内底面どうしを連通させる水路１４が形成されている。
【００１２】
給水容器５は、図５に示すごとく給水口１５を有する比較的細い有底の円筒形状にプラスチック成形されており、給水口１５は内部に所要量の水を収容した後にアルミ箔等の破断容易なシール材１６で塞がれる。この給水容器５は給水口１５を下にして外容器１の第２収容室１２にこれの上方から垂直姿勢で収容する。第２収容室１２の内底面には前記シール材１６を突き破ることのできる円錐形または角錐形等の尖鋭的な突起１７が上向きに一体突設されている。
【００１３】
筒壁１０の前後には受け溝１９・１９がそれぞれ前後対称形に切り欠き形成されている。すなわち各受け溝１９は、図１に示すごとく筒壁１０の上端から上下中間高さ位置に到る垂直状の止め壁面２０と、止め壁面２０の下端から筒壁１０の上端縁に到る傾斜案内壁面２１とを有する。前後の受け溝１９・１９は、止め壁面２０・２０どうしが前後の対向位置にあり、前側の受け溝１９は傾斜案内壁面２１の上端が左側の縦溝１３に近い筒壁１０の上端縁につながっており、後ろ側の受け溝１９は傾斜案内壁面２１の上端が右側の縦溝１３に近い筒壁１０の上端縁につながっている。
【００１４】
給水容器５の外周側面には、対向位置に線状の突部２２・２２を縦方向に沿って一体に突設してある。すなわち各突部２２は給水容器５の筒壁の外周面に上端から下向きに延びる縦長のリブ状に形成されており、各突部２２の下端の受け面２２ａが、該筒壁の上下中間高さ位置、具体的には上下中央部の下方寄りに位置している。いま、これら両突部２２・２２がほぼ前後に位置する状態で筒壁１０内の第２収容室１２に給水容器５を上方から挿入すると、図１および図３に示すごとく両突部２２・２２の下端の受け面２２ａが前後の各受け溝１９の傾斜案内壁面２１に受け止められて滑り降り、両突部２２が止め壁面２０にそれぞれ当たった状態で両突部２２の受け面２２ａが受け溝１９すなわち傾斜案内壁面２１の最下端（止め壁面２０の下端と交わる部位）に受け止められて下降限界が規制されている。これで給水容器５は、使用前の収納状態において上端部が筒壁１０上に露出して、底側のシール材１６が突起１７に当たることなく該突起１７より少し上方に間隔をおいて静止固定されている。
【００１５】
使用時には、蓋９を外し、給水容器５の上端部を手でつかんでこれを右方向に回転させながら両突部２２の受け面２２ａを各傾斜案内壁面２１に沿うように持ち上げて行き、受け面２２ａを筒壁１０の上端縁に沿わせて、両突部２２・２２を左右の各縦溝１３・１３にそれぞれ落とし込む。これで給水容器５を指先にて下方へ押し込むと、図４に示すごとくシール材１６が突起１７で突き破られ、給水容器５内の水が給水口１５から第２収容室１２の内底面上に流出落下する。第２収容室１２の内底面は水路１４に向かって下り傾斜状に形成されている。これにより給水容器５の給水口１５から出した水は、その傾斜内底面上を流れ下り、水路１４を経て第１収容室１１の内底に速やかに流れ込んで溜まる。
【００１６】
内容器４は、金属材など耐熱性材料からなる有底筒状の容器本体２５の底に通水孔２６を設け、その上面に蒸散口２７を設けてあり、内底に生石灰等の発熱剤３を収容するとともに、この発熱剤３の上にピレスロイド系殺虫剤とオキサジアゾール系殺虫剤の混合剤等からなる燻煙殺虫剤２を収容している。第１収容室１１の内底面には支持リブ２９を放射状に設け、内容器４はその支持リブ２９上に載るように第１収容室１１の中に上方から出し入れ自在に収容される。これで内容器４の底と第１収容室１１の内底面との間に、水路１４からの水が流れ込む。使用前には発熱剤３が空気中の湿気と反応することのないように、内容器４の全体が防湿性の高いアルミ箔などの袋（図示せず）の中に入っている。使用時には内容器４はその袋を破り取ってから使用する。
【００１７】
上記構成の蒸散器は、外容器１に内容器４と給水容器５とを収納して蓋９で閉じた状態で、全体が密封包装されている。この包装状態において、給水容器５は突部２２の受け面２２ａが受け溝１９に受け止められている。給水容器５の上方への遊動は蓋９で規制されており、前記受け面２２ａが筒壁１０の上端縁にまで乗り上がることはない。使用時には外側の包装を解いて外容器１から蓋９を取り外し、前記突部２２を縦溝１３に嵌合して給水容器５を下方へ押し込み、シール材１６を突起１７で突き破る。すると、給水容器５内の水は給水口１５から流出し、水路１４を通って第１収容室１１の内底に所定量だけ溜まり、内容器４の通水孔２６を有する底が浸水する。シール材１６を突き破った後は蓋９を外容器１に再び被せ付ける。内容器４内の発熱剤３は通水孔２６から入ってくる水と反応して発熱し、加熱された燻煙殺虫剤２は蒸気となって蒸散口２７、蓋９の中央開口９ａから外部へ発散する。
【００１８】
（第２実施例）図５ないし図７は本発明に係る蒸散器の第２実施例として加熱蒸散殺虫器を示しており、これでは前記受け溝１９が筒壁１０の上端縁から上下中間高さ位置にまでストレートの縦溝として形成されている点が第１実施例と異なるだけであり、他の構成は実質的に第１実施例と同一であるので説明を省略する。この第２実施例によれば、図５および図６の梱包輸送時には、筒壁１０内の第２収容室１２に給水容器５の下部が収納された状態で突部２２が受け溝１９に嵌合して突部２２の下端の受け面２２ａが受け溝１９の下端で受け止められている。この状態から使用時には、給水容器５を真っすぐ上方にいったん抜き外し、突部２２と受け溝１９との嵌合を解いたのち、給水容器５を回して突部２２を縦溝１３に嵌合することになる。
【００１９】
その他、第２収容室１２の内底面上に設けるべき突起１７は、外容器１と一体に形成される必要はなく、別体に形成して該内底面上に後付けしたものでもよく、要はシール材１６を突き破る機能を有するものであれば足りる。内容器４に入れるべき薬剤としては、例えば消臭剤または芳香剤とし、本発明の蒸散器を自動車の車内にセットして用いるようにしてもよい。突部２２の受け面２２ａは、筒壁１０内に給水容器５の下部がぐら付くことなく嵌合する高さ位置にあればよい。突部２２は給水容器５に１箇所だけ設けてあってもよいし、例えば外周の三等分点位置に設けてあってもよい。
【００２０】
【発明の効果】
本発明の蒸散器では、外容器１内に水と反応して所望の気体を蒸散する薬剤入りの内容器４が、これに水を供給する給水容器５と共に収納されている。従って、給水容器５に詰め込んである水を過不足なく薬剤に供給できる。その際に梱包輸送状態では、給水容器５に設けた突部２２の受け面２２ａが筒壁１０の受け溝１９に確りと受け止められているので、外部衝撃を受けても、筒壁１０内の第２収容室１２において給水容器５が下方に落ち込みシール材１６が破れて内部の水が流出することはない。この結果、使用時まで水と接してはならない内容器４を安全に輸送し保管しておくことができる。
【００２１】
そのうえで、使用時には、前記突部２２を受け溝１９から縦溝１３へ嵌合し直し、給水容器５を下方に押し込みさえすれば、シール材１６が突起１７で突き破られて内部の水が内容器４の第１収容室１１へと自動的に流れ込むようにしたので、使い勝手もよい。
【００２２】
複数の突部２２が給水容器５の筒壁の上端から下向きに延びる縦長リブ状に複数形成されていると、給水容器５が使い捨てに適うよう薄肉のプラスチック成型品としてあっても、該突部２２で給水容器５をよく補強し、給水容器５を手づかみしたとき内部の水がシール材１６を押し破って不用意に出ることを防ぎ、かつ給水容器５を手で右または左に回転操作するときにも、指先が突部２２に掛かって回転操作を容易に行えることにもなる。

It slides up along the wall surface 21 from the lower end of 21. Next, as shown in FIG. 4, the protrusion 22 is aligned with the longitudinal groove 13, the water supply container 5 is reinserted into the second storage chamber 12, and the water supply container 5 is pushed in by hand. The water in the water supply container 5 flows out from the water supply port 15 to the outside. This effluent water is guided to the water passage hole 26 of the inner container 4 through the water channel 14 in the outer container 1, and the chemical in the inner container 4 reacts with the inflowing water through the water passage hole 26 and evaporates. Specifically, the exothermic agent 3 reacts with the inflowing water, and the smoke insecticide 2 is heated by the exothermic agent 3 to become steam, and is emitted from the transpiration port 27.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
(First Embodiment) FIGS. 1 to 4 show a heat transpiration insecticidal device as a first embodiment of a transpiration device according to the present invention. A smoke insecticide 2 and an exothermic agent 3 are placed in an outer container 1. The accommodated inner container 4 and the water supply container 5 are accommodated so that they can be taken in and out from above.
[0011]
As shown in FIGS. 2 and 3, the outer container 1 is detachable from a plastic bottomed cylindrical container body 6 whose upper surface is open and an upper end opening 7 of the container body 6 to close the upper surface of the container body 6. And a plastic lid 9 to be mounted. The lid 9 is formed in an annular shape having a central opening 9a. A first storage chamber 11 outside the cylindrical wall 10 in which the inner container 4 can be taken in and out from above, by integrally standing a circular cylindrical wall 10 from a lower surface of the container body 6 on the right side in the figure in the figure, A second storage chamber 12 in the cylindrical wall 10 in which the water supply container 5 is stored so as to be movable up and down from above is partitioned and formed on the left and right. The cylindrical wall 10 is provided with vertical grooves 13 and 13 at substantially opposite positions on the left and right sides, and a water channel that allows the inner bottom surfaces of the second storage chamber 12 and the first storage chamber 11 to communicate with each other at the lower end of the left vertical groove 13. 14 is formed.
[0012]
The water supply container 5 is plastic-molded into a relatively thin bottomed cylindrical shape having a water supply port 15 as shown in FIG. 5, and the water supply port 15 easily breaks aluminum foil or the like after containing a required amount of water therein. The sealing material 16 is closed. This water supply container 5 is accommodated in the second storage chamber 12 of the outer container 1 in a vertical posture from above, with the water supply port 15 facing downward. On the inner bottom surface of the second storage chamber 12, a sharp protrusion 17 such as a cone shape or a pyramid shape capable of breaking through the sealing material 16 is integrally projected upward.
[0013]
Receiving grooves 19 and 19 are formed in the front and rear sides of the cylindrical wall 10 so as to be symmetrically cut out. That is, as shown in FIG. 1, each receiving groove 19 has a vertical stop wall surface 20 extending from the upper end of the cylindrical wall 10 to the vertical middle height position, and an inclination extending from the lower end of the stop wall surface 20 to the upper edge of the cylindrical wall 10. And a guide wall surface 21. The front and rear receiving grooves 19 and 19 have the stop wall surfaces 20 and 20 at the front and rear facing positions, and the front receiving groove 19 is at the upper edge of the cylindrical wall 10 with the upper end of the inclined guide wall surface 21 close to the left vertical groove 13. The rear receiving groove 19 is connected to the upper end edge of the cylindrical wall 10 whose upper end of the inclined guide wall surface 21 is close to the vertical groove 13 on the right side.
[0014]
On the outer peripheral side surface of the water supply container 5, linear protrusions 22, 22 are integrally projected along the vertical direction at opposing positions. That is, each protrusion 22 is formed in a longitudinally long rib shape extending downward from the upper end on the outer peripheral surface of the cylindrical wall of the water supply container 5, and the receiving surface 22 a at the lower end of each protrusion 22 has an upper and lower intermediate height of the cylindrical wall. It is located near the lower part of the vertical position, specifically the upper and lower central part. Now, when the water supply container 5 is inserted from above into the second storage chamber 12 in the cylindrical wall 10 in a state in which both the protrusions 22 and 22 are positioned substantially front and rear, both protrusions 22. The receiving surface 22a at the lower end of 22 is received by the inclined guide wall surface 21 of each of the front and rear receiving grooves 19 and slides down. 19, that is, the lower limit is regulated by being received at the lowermost end of the inclined guide wall surface 21 (the portion intersecting the lower end of the stop wall surface 20). As a result, the water supply container 5 is fixed stationary with a gap slightly above the protrusion 17 so that the upper end portion of the water supply container 5 is exposed on the cylindrical wall 10 before being used and the bottom sealing material 16 does not hit the protrusion 17. Has been.
[0015]
During use, the lid 9 is removed, the upper end portion of the water supply container 5 is grasped by hand, and the receiving surface 22a of both protrusions 22 is lifted along the respective inclined guide wall surfaces 21 while rotating it clockwise. The protrusions 22 and 22 are dropped into the left and right vertical grooves 13 and 13 with the surface 22a along the upper edge of the cylindrical wall 10 respectively. When the water supply container 5 is pushed downward with the fingertip, the sealing material 16 is pierced by the protrusion 17 as shown in FIG. 4, and the water in the water supply container 5 is on the inner bottom surface of the second storage chamber 12 from the water supply port 15. Fall into the spill. The inner bottom surface of the second storage chamber 12 is formed to be inclined downward toward the water channel 14.

【The invention's effect】
In the evaporator of the present invention, an inner container 4 containing a medicine that reacts with water to evaporate a desired gas is housed in an outer container 1 together with a water supply container 5 that supplies water thereto. Therefore, the water packed in the water supply container 5 can be supplied to the medicine without excess or deficiency. At that time, in the package transportation state, the receiving surface 22a of the protrusion 22 provided in the water supply container 5 is firmly received by the receiving groove 19 of the cylindrical wall 10, so that even if it receives an external impact, In the second storage chamber 12, the water supply container 5 does not fall down and the sealing material 16 is broken and the water inside does not flow out. As a result, the inner container 4 that should not come into contact with water until use can be safely transported and stored.
[0021]
In addition, at the time of use, as long as the projection 22 is re-fitted from the receiving groove 19 to the vertical groove 13 and the water supply container 5 is pushed downward, the sealing material 16 is pierced by the projection 17 and the water inside is filled. Since it automatically flows into the first storage chamber 11 of the container 4, it is easy to use.
[0022]
When a plurality of protrusions 22 are formed in the shape of vertically long ribs extending downward from the upper end of the cylindrical wall of the water supply container 5, the protrusions are formed even if the water supply container 5 is a thin plastic molded product so as to be disposable. The water supply container 5 is well reinforced at 22, and when the water supply container 5 is gripped, the internal water is prevented from inadvertently breaking through the sealing material 16, and the water supply container 5 is rotated to the right or left by hand.
