第４の手段として、以下の通り構成した。即ち、前記第１の手段に於いて、ロック機構を、蛇腹10の収縮を防止する係止位置から蛇腹10の収縮が可能な係止解除位置までの可逆的な移動が可能にカバー筒Ｃに嵌合させたストッパーＤを設けて構成した。 The fourth means is configured as follows. That is, in the first means, the cover mechanism C can be reversibly moved from the locking position for preventing the bellows 10 to contract to the unlocking position for allowing the bellows 10 to contract. The stopper D fitted was provided and constituted.

That is, in the fourth means, the stopper D is slidably fitted in a horizontally extending slide groove 43 formed in the cover cylinder C, and the inner lower surface is an upward step portion of the bellows 10 part outward. After the slide groove 43 is slid from the locked state in contact with and locked to the portion 20, the first locking groove 21 formed in the upward stepped portion 20 and the second locking groove 44 provided continuously with the slide groove 43 are provided. It is possible to reversibly move to the unlocked state fitted and lowered.

第６の手段として、以下の通り構成した。即ち、前記第１の手段乃至第５の手段のいずれかの手段に於いて、吐出弁30を、容器体Ａ内上部に張設した柔軟で弾力性に富む材質で形成された遮蔽壁Ｂに設けたスリットとして構成した。 The sixth means is configured as follows. That is, in any one of the first to fifth means, the discharge valve 30 is formed on the shielding wall B formed of a flexible and elastic material stretched on the upper part in the container body A. It was configured as a provided slit.

第７の手段として、以下の通り構成した。即ち、前記第１の手段乃至第６の手段のいずれかの手段に於いて、容器体Ａが周壁３と別体に形成された底部材A₁を備えている。 The seventh means is configured as follows. That is, in any one of the first to sixth means, the container body A includes a bottom member A ₁ formed separately from the peripheral wall 3.

本発明の塗布容器１は、ロック機構を解除して容器体Ａ底部を押し込むという簡単な操作により液の吐出を行え、吐出した液は頂部表面で引き延ばすことができて使い勝手が良い。また、容器体Ａ底部を押し込むことで収容液の吐出を行えるため、手の感触で吐出量，吐出速度等をコントロールできる利点がある。また、不使用時はロック機構の存在で蛇腹10が収縮する虞れがなく、不用意な液の漏出等を確実に防止できるものである。更に、構造も簡単で安価に製造できる利点も兼ね備えている。 The application container 1 of the present invention can discharge the liquid by a simple operation of releasing the lock mechanism and pushing the bottom of the container body A, and the discharged liquid can be stretched on the top surface, which is convenient. Further, since the contained liquid can be discharged by pushing the bottom of the container body A, there is an advantage that the discharge amount, the discharge speed and the like can be controlled with the touch of the hand. Further, when not in use, there is no possibility of the bellows 10 contracting due to the presence of the lock mechanism, and inadvertent liquid leakage can be reliably prevented. Furthermore, the structure is simple and has the advantage that it can be manufactured at low cost.

また、容器体Ａの蛇腹10形成位置の環状窓11に、カバー筒Ｃの嵌合孔42を介して着脱可能に嵌合させたストッパーを設けてロック機構を構成した場合には、ロック解除及びロック付与が簡単に行える。 When the lock mechanism is configured by providing a stopper that is detachably fitted to the annular window 11 of the container body A at the position where the bellows 10 is formed through the fitting hole 42 of the cover cylinder C, Lock can be easily assigned.

嵌合孔42を介して環状窓11に嵌合させた嵌合部50と、嵌合部50の両側よりそれぞれ延設して容器体Ａ外面に嵌合させた腕板部51と、嵌合部50の上面或いは下面の外側縁部より突設してカバー筒Ｃ外面に当接係止させた係止板部52とでストッパーＤを構成した場合には、各腕板部51を両側から掴んで簡単に取り外すことができる。また、装着に当たって係止板部52の存在で嵌合部50が必要以上に嵌合孔42内に侵入するのを防止できる。 A fitting portion 50 fitted to the annular window 11 through the fitting hole 42, an arm plate portion 51 extending from both sides of the fitting portion 50 and fitted to the outer surface of the container body A, and fitting When the stopper D is constituted by the locking plate portion 52 that protrudes from the outer edge of the upper surface or the lower surface of the portion 50 and is brought into contact with and locked to the outer surface of the cover cylinder C, each arm plate portion 51 is connected from both sides. It can be easily grasped and removed. In addition, it is possible to prevent the fitting portion 50 from entering the fitting hole 42 more than necessary due to the presence of the locking plate portion 52 during mounting.

ロック機構を、蛇腹10の収縮を防止する係止位置から蛇腹10の収縮が可能な係止解除位置までの可逆的な移動が可能にカバー筒Ｃに嵌合させたストッパーＤを設けて構成した場合には、ストッパーＤが常時カバー筒Ｃに嵌合されているため、紛失する等の不都合がない。 The locking mechanism is configured by providing a stopper D fitted to the cover cylinder C so as to be able to reversibly move from a locking position that prevents the bellows 10 to contract to an unlocking position that allows the bellows 10 to contract. In this case, since the stopper D is always fitted to the cover cylinder C, there is no inconvenience such as loss.

カバー筒Ｃに穿設した水平方向に延びるスライド溝43にスライド可能に嵌合させ、且つ、内側下面を蛇腹10部分外方の上向き段部20に当接係止させたロック状態から、スライド溝43をスライドさせた後、上向き段部20に穿設した第１係止溝21及びスライド溝43に連設した第２係止溝44に嵌合下降させたロック開放状態への可逆的な移動が可能にストッパーＤを構成した場合には、同様にストッパーの紛失の虞れがなく、また、係止位置から係止解除位置までのルートが単純で円滑な移動が可能となる。 From the locked state in which the slide tube 43 is slidably fitted in the slide groove 43 extending in the horizontal direction formed in the cover tube C, and the inner lower surface is in contact with and locked to the upward stepped portion 20 outside the bellows 10 part, the slide groove After sliding 43, the first locking groove 21 drilled in the upward stepped portion 20 and the second locking groove 44 connected to the sliding groove 43 are reversibly moved to the unlocked state. In the case where the stopper D is configured so as to be able to perform the same, there is no risk of the stopper being lost, and the route from the locking position to the locking release position is simple and smooth.

容器体Ａ内上部に張設した柔軟で弾力性に富む材質で形成された遮蔽壁Ｂに設けたスリットとして吐出弁30を構成した場合には、遮蔽壁Ｂにより収容室Ｒを画成することができる便利があり、また、その構造も簡単で製造が容易となる利点もある。更に、液の吐出時に遮蔽壁Ｂは先端側へ膨出する如く弾性変形してスリットを開くため、吐出量、吐出速度のコントロールがより行い易くなる。 When the discharge valve 30 is configured as a slit provided in the shielding wall B formed of a flexible and elastic material stretched on the upper part of the container body A, the accommodation chamber R is defined by the shielding wall B. There is also an advantage that the structure is simple and the manufacture is easy. Further, since the shielding wall B is elastically deformed so as to bulge toward the distal end side when the liquid is discharged and the slit is opened, it becomes easier to control the discharge amount and the discharge speed.

容器体Ａが周壁３と別体に形成された底部材A₁を備えている場合には、底部からの液の充填が可能となる。 When the container body A includes the bottom member A ₁ formed separately from the peripheral wall 3, the liquid can be filled from the bottom.

以下、本発明の実施例の形態を図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１乃至図３は本発明の塗布容器１の一例を示すもので、塗布容器１は比較的流動性の大きい粘性液体を収容液の好ましい対象としている。塗布容器１は、容器体Ａと、遮蔽壁Ｂと、カバー筒Ｃと、ストッパーＤと、キャップＥとを備えている。 1 to 3 show an example of an application container 1 according to the present invention, and the application container 1 uses a viscous liquid having a relatively large fluidity as a preferable target of the containing liquid. The application container 1 includes a container body A, a shielding wall B, a cover cylinder C, a stopper D, and a cap E.

容器体Ａは、底壁２周縁より周壁３を立設し、周壁３の外周面は上部に於いて第１段部４及び第２段部５により二段階に縮径されており、また、内周面は上部に於いて下向き段部６を介して上端部を縮径している。第１段部４及び第２段部５間の周壁３外面にはカバー筒Ｃを固定するための突条７を周設している。更に、周壁３の上端縁より球面状に上方へ突出する頂壁８を延設し、頂壁８の中央部に吐出孔９を穿設している。 The container body A has a peripheral wall 3 upright from the periphery of the bottom wall 2, and the outer peripheral surface of the peripheral wall 3 is reduced in diameter in two steps by the first step portion 4 and the second step portion 5 at the top, The inner peripheral surface is reduced in diameter at the upper end portion via a downward stepped portion 6 at the upper portion. On the outer surface of the peripheral wall 3 between the first step portion 4 and the second step portion 5, a ridge 7 for fixing the cover tube C is provided. Further, a top wall 8 projecting upward in a spherical shape from the upper end edge of the peripheral wall 3 is extended, and a discharge hole 9 is formed in the center of the top wall 8.

また、周壁３上部の一部を蛇腹10に形成している。蛇腹10の形成部分は、周壁３を貫通する環状窓11の内周縁上下に蛇腹10の上端縁及び下端縁をそれぞれ一体に連結している。環状窓11は、その外縁部上下より外方へ突設した上部突条12及び下部突条13により奥行きを広げている。各上部突条12及び下部突条13はカバー筒Ｃと容器体Ａとの間に隙間を設ける役割も果たしている。尚、本例では容器体Ａを、底部材A₁と、中間部材A₂と、上部材A₃との３部材で構成しており、底部材A₁を中間部材A₂に嵌着する前に液を底部から充填できる如く構成しており、底部材A₁と、中間部材A₂と、上部材A₃とはそれぞれ合成樹脂により形成されている。本発明の容器体Ａは本例の如く全体を合成樹脂で構成しても、或いは、蛇腹10及びその取付部分を柔軟な材質等で構成することも可能である。その場合インサート成形を採用して容器体を形成すると良い。 A part of the upper part of the peripheral wall 3 is formed in the bellows 10. The formation part of the bellows 10 integrally connects the upper end edge and the lower end edge of the bellows 10 respectively above and below the inner peripheral edge of the annular window 11 penetrating the peripheral wall 3. The annular window 11 is expanded in depth by an upper ridge 12 and a lower ridge 13 protruding outward from the upper and lower edges of the outer edge. Each upper ridge 12 and lower ridge 13 also serve to provide a gap between the cover tube C and the container body A. Incidentally, the container body A in the present example, the bottom member A _1, the intermediate member A _2, constitutes three members of the upper member A _3, prior to fitting the bottom member A ₁ to the intermediate member A ₂ liquid has been composed as can be filled from the bottom to a bottom member a _1, the intermediate member a _2, are each formed by a synthetic resin and the upper member a _3. The container body A of the present invention can be entirely made of a synthetic resin as in this example, or the bellows 10 and its mounting portion can be made of a flexible material or the like. In that case, it is preferable to form the container body by adopting insert molding.

遮蔽壁Ｂは柔軟で弾力性に富み、シリコーンゴムにより形成されている。また、下向き段部６下面に周縁部上面を当接する位置に周縁部を嵌着固定して張設され、その下方に液体を収容する収容室Ｒを画成している。周縁部の固定方法は接着，溶着等の適宜固着手段を採用しても、或いは突条等を遮蔽壁Ｂ下面に係止させる等の手段を採用しても良い。遮蔽壁Ｂにはスリットを穿設してこの部分を吐出弁30として構成している。スリットは、放射状に複数穿設されている。尚、スリットの形状は放射状に限定されるものではなく、遮蔽壁Ｂが上方へ弾性変形することにより開孔する形態であれば種々採用できる。また、遮蔽壁Ｂの材質もシリコーンゴムに限らず、他のエラストマーを採用することができる。 The shielding wall B is flexible and rich in elasticity, and is made of silicone rubber. Further, the peripheral portion is fitted and fixed at a position where the upper surface of the peripheral portion abuts the lower surface of the downward stepped portion 6, and a storage chamber R for storing liquid is defined below the peripheral portion. As a method for fixing the peripheral portion, an appropriate fixing means such as adhesion or welding may be employed, or a means such as locking the ridge to the lower surface of the shielding wall B may be employed. A slit is formed in the shielding wall B, and this portion is configured as a discharge valve 30. A plurality of slits are formed radially. The shape of the slit is not limited to a radial shape, and various forms can be adopted as long as the shielding wall B is opened by elastic deformation. The material of the shielding wall B is not limited to silicone rubber, and other elastomers can be used.

カバー筒Ｃは合成樹脂により形成され、円筒状の周壁部40上端縁より内方へフランジ部41を延設して構成している。第１段部４上においてフランジ部41の先端を第１段部４と突条７とに挟持させて嵌着固定しており、周壁部40を、上部突条12及び下部突条13の突出幅だけ、容器体周壁３と僅かな隙間をあけて垂下させている。周壁部40の下端部は容器体の底部を押し込むために容器体底面より上方位置まで垂下している。その位置は蛇腹10の長さ等を考慮して適宜選択すれば良い。カバー筒Ｃには、ストッパーＤを嵌合させるための嵌合孔42を穿設している。嵌合孔42は、環状窓11と同じレベルに同じ縦幅で形成され、その横幅はストッパーＤの後述する嵌合部の横幅と同程度の横幅で、嵌合部が着脱自在に嵌合できる如く構成している。 The cover cylinder C is made of synthetic resin, and is configured by extending a flange portion 41 inward from the upper end edge of the cylindrical peripheral wall portion 40. On the first step portion 4, the front end of the flange portion 41 is sandwiched and fixed between the first step portion 4 and the protrusion 7, and the peripheral wall portion 40 is protruded from the upper protrusion 12 and the lower protrusion 13. Only the width is suspended from the container body peripheral wall 3 with a slight gap. The lower end portion of the peripheral wall portion 40 hangs down to a position above the bottom surface of the container body in order to push the bottom portion of the container body. The position may be appropriately selected in consideration of the length of the bellows 10 and the like. The cover tube C is provided with a fitting hole 42 for fitting the stopper D. The fitting hole 42 is formed at the same level as the annular window 11 with the same vertical width, and the horizontal width is the same as the horizontal width of the fitting portion described later of the stopper D, so that the fitting portion can be detachably fitted. It is configured as follows.

ストッパーＤは合成樹脂製で、蛇腹10の収縮の防止及び開放を司るロック機構の一役を担うものであり、嵌合孔42を介して環状窓11外縁部に嵌合する肉厚な円弧板状の嵌合部50を備え、嵌合部50の両側の外側縁部からそれぞれ嵌合部50と同じ縦幅で、カバー筒Ｃ外周に嵌合する薄肉円弧板状の腕板部51を延設している。また、嵌合部50の上面外側縁部より上方へ嵌合部50の嵌合孔42及び環状窓11内への余分な侵入を防止する係止板部52を立設している。 The stopper D is made of a synthetic resin and plays a role of a locking mechanism for preventing and releasing the bellows 10 from contracting, and is a thick circular arc plate that is fitted to the outer edge portion of the annular window 11 through the fitting hole 42. And a thin arc plate-like arm plate portion 51 that extends from the outer edge portions on both sides of the fitting portion 50 and has the same vertical width as the fitting portion 50 and is fitted to the outer periphery of the cover cylinder C. is doing. In addition, a locking plate portion 52 that prevents an excessive intrusion into the fitting hole 42 of the fitting portion 50 and the annular window 11 is provided above the outer edge of the upper surface of the fitting portion 50.

キャップＥも合成樹脂により形成され、第２段部５上方の容器体周壁３外周に嵌合させた装着筒部60の上端縁より球面状に上方へ突出する頂板61を延設し、頂板61裏面より垂設した棒栓62を吐出孔９に液密に嵌合して着脱自在に装着している。 The cap E is also formed of a synthetic resin, and a top plate 61 that extends upward in a spherical shape from the upper end edge of the mounting cylinder portion 60 fitted on the outer periphery of the container body peripheral wall 3 above the second step portion 5 extends. A rod plug 62 suspended from the back surface is fitted in the discharge hole 9 in a liquid-tight manner and is detachably mounted.

上記の如く構成した塗布容器１を使用する場合に付いて説明する。図１に示す状態から例えばキャップＥを取り外し、次いでストッパーＤを側方に抜く如く取り外す。この際各腕板部51外面を、例えばそれぞれ親指と人差指で挟んで側方に引けば容易に取り外すことが出来る。次いで図３に示す如く、容器を傾けて容器体Ａ底部を押し込むと蛇腹10が収縮して収容室Ｒ内が加圧され、それに伴って遮蔽壁Ｂが先端側へ膨らむ如く弾性変形するとともにスリットが開き、即ち吐出弁30が開いて、収容室Ｒ内の液は吐出孔９から外部へ吐出される。容器体底部の押圧を解除すれば蛇腹10の弾性復元力で容器体Ａは元の状態に戻り、遮蔽壁Ｂも元の状態に戻り吐出弁30が閉じる。塗布した液は頂板61の上面により引き延ばすことができる。 The case where the coating container 1 configured as described above is used will be described. For example, the cap E is removed from the state shown in FIG. 1, and then the stopper D is removed so as to be pulled out sideways. At this time, the outer surface of each arm plate portion 51 can be easily removed by, for example, sandwiching it between the thumb and the index finger and pulling it sideways. Next, as shown in FIG. 3, when the container is tilted and the bottom of the container body A is pushed in, the bellows 10 contracts and the inside of the storage chamber R is pressurized, so that the shielding wall B is elastically deformed so that it swells toward the tip side and slits. Is opened, that is, the discharge valve 30 is opened, and the liquid in the storage chamber R is discharged from the discharge hole 9 to the outside. When the pressure at the bottom of the container body is released, the container body A returns to the original state by the elastic restoring force of the bellows 10, and the shielding wall B also returns to the original state, and the discharge valve 30 is closed. The applied liquid can be stretched by the upper surface of the top plate 61.

図４はストッパーＤを容器体Ａの下部に設けた例を示す。容器体Ａは、周壁３上部に第１突条14を、周壁下部に第１突条14と同突出幅で且つ相互に所定幅の間隔をあけて第２突条15及び第３突条16を突周設し、第１突条14の上面を第１段部４とし、第２突条と第３突条との間を環状窓11として構成している。また、容器体Ａを、底部材A₁と、中間及び上部材A₄との２部材で構成しており、この場合も底部材A₁を中間及び上部材A₄に嵌着する前に液を底部から充填できる如く構成している。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。 FIG. 4 shows an example in which the stopper D is provided in the lower part of the container body A. The container body A has a first protrusion 14 on the upper part of the peripheral wall 3 and a second protrusion 15 and a third protrusion 16 on the lower part of the peripheral wall having the same protrusion width as the first protrusion 14 and a predetermined width therebetween. The upper surface of the first protrusion 14 is the first step portion 4, and the space between the second protrusion and the third protrusion is the annular window 11. Further, the container body A is composed of two members, a bottom member A ₁ and an intermediate and upper member A ₄ , and in this case also before the bottom member A ₁ is fitted to the intermediate and upper member A ₄ , Is configured to be filled from the bottom. The other configuration is the same as that of the example of FIG.

図５及び図６は図１の例に於いて、ストッパーの形態が異なる例である。容器体Ａは、周壁３の上部に設けた環状窓11の下面に連続する上向き段部20外縁所定位置に上端を開放した第１係止溝21を縦設している。また、カバー筒Ｃは、上部所定位置に横長なスライド溝43を穿設し、スライド溝43の一端より下方へ第２係止溝44を縦設している。第２係止溝44は第１係止溝21の外方に位置している。 5 and 6 are examples in which the form of the stopper is different from the example of FIG. The container body A is vertically provided with a first locking groove 21 having an upper end opened at a predetermined position on the outer edge of the upward stepped portion 20 continuous with the lower surface of the annular window 11 provided on the upper portion of the peripheral wall 3. Further, the cover cylinder C has a horizontally long slide groove 43 at a predetermined upper position, and a second locking groove 44 is vertically formed below one end of the slide groove 43. The second locking groove 44 is located outside the first locking groove 21.

ストッパーＤは、水平なスライド溝43の外側に位置する外板53と内側に位置する内板54を、スライド溝43を横方向へスライドする連結板55で連結し、内板54の内面には上向き段部20上面に下面を当接係止する係合突起56を突設している。ストッパーＤは、図６(a) に示す如く、係合突起56を上向き段部20上に当接係止させて蛇腹10が収縮しないロック状態を維持し、また、スライド溝43に沿って回動させた後、図６(b) に示す如く、係合突起56を第１係止溝21に、連結板55を第２係止溝44にそれぞれ嵌合させて下方へ押し下げるとロック状態が解除されて蛇腹10の収縮が可能となる。従って、第１係止溝21及び第２係止溝44は蛇腹が収縮するに充分な深さを必要とする。その他の構成は図１の例と同様であるため、同符号を付して説明を省略する。また、液の吐出作用は図１の例と同様であり、使用後には再びストッパーＤを元の位置に戻しておけば適宜載置位置に塗布容器１を載置しておいても蛇腹10の収縮は起こらずに吐出弁30が開くこともない。尚、本例ではストッパーＤを一箇所設けた例を示したが、この種のストッパーは対向位置に二箇所設けても良い。その場合にはロック時に於ける蛇腹10の収縮をより安定的に防止できる。 The stopper D connects the outer plate 53 positioned outside the horizontal slide groove 43 and the inner plate 54 positioned inside by a connecting plate 55 that slides the slide groove 43 in the lateral direction. An engaging protrusion 56 is provided on the upper surface of the upward step portion 20 so as to abut and lock the lower surface. As shown in FIG. 6A, the stopper D maintains the locked state in which the bellows 10 is not contracted by abutting and locking the engaging protrusion 56 on the upward stepped portion 20, and the stopper D rotates along the slide groove 43. After the movement, as shown in FIG. 6 (b), when the engaging projection 56 is fitted in the first locking groove 21 and the connecting plate 55 is fitted in the second locking groove 44 and pushed downward, the locked state is obtained. When released, the bellows 10 can be contracted. Therefore, the first locking groove 21 and the second locking groove 44 need to have a depth sufficient for the bellows to contract. The other configuration is the same as that of the example of FIG. Also, the liquid discharging action is the same as in the example of FIG. 1, and after use, if the stopper D is returned to its original position again, the bellows 10 will remain even if the applicator container 1 is properly placed at the placement position. The discharge valve 30 does not open without contracting. In addition, although the example which provided the stopper D in this example was shown, you may provide this kind of stopper in two places at an opposing position. In that case, contraction of the bellows 10 at the time of locking can be prevented more stably.
