Description

【発明の詳細な説明】 放出体用のピストンアセンブリを備えた散布器（技術分野） 本発明は散布器に係り、特に弁を手動することによってスプレーするようにピス トンが駆動され得る手持ちスプレー散布器に関する。[Detailed description of the invention] Spreader with piston assembly for the emitter (technical field) The present invention relates to a sprayer, and more particularly, to a sprayer for spraying by manually operating a valve. This invention relates to a hand-held spray applicator that can be driven by a ton.

（背景技術） 周知の手持ちスプレー散布器においてはピストンが放出体の丁位に位置するよう に容器内に収容される。この容２３の端部の弁に向かってピストンが駆動される と放出体が弁を介して流動される。(Background technology) In known hand-held spray applicators, the piston is positioned exactly on the ejector. contained in a container. A piston is driven toward the valve at the end of this container 23. and the emitter are flowed through the valve.

この種の散布器によれば駆動推進体として加圧ガスを使用する霧化スプレー散布 器の改良器が構成されており、加圧ガスは放出体に混入される。加圧ガスは通常 炭化水素を含んで使用され、大気汚染を防ぐべく顕著に寄与するよう次第に作用 が増大する。例えば大気中に放出される炭化水素はスモッグを形成する窒素酸化 物および太陽光線と反応し得る。According to this type of sprayer, atomized spray spraying using pressurized gas as the driving propellant A vessel improver is constructed in which pressurized gas is mixed into the emitter. Pressurized gas is usually Contains hydrocarbons and gradually acts to make a significant contribution to preventing air pollution. increases. For example, hydrocarbons released into the atmosphere are oxidized to nitrogen, which forms smog. Can react with objects and sunlight.

これにより機械的な推進力が発生して無ガスのスプレー散布器が提供される。例 えばポンプ式散布器は使用者がスプレーを行う都度、ポンプのステムが機械的に 変位されるように構成される。当該散布器はエネルギが残留せず、スプレー長を 長手にするよりも、間欠的にスプレーを噴出する形態をとるように放出体が放出 される。This generates mechanical propulsion and provides a gas-free spray applicator. example For example, with a pump-type sprayer, the pump stem mechanically closes each time the user sprays. configured to be displaced; The sprayer has no residual energy and reduces spray length. The emitter emits a spray intermittently rather than in a long way. be done.

他の散布器としては、米国特許第３．８１５．７８７号、同第３．１９５゜１６ ８号、同第２．７２８．０９７号および同第２．７３８．９０５号に開示のもの が挙げられ、機械的動作により散布する構成が提供される。Other spray devices include U.S. Pat. No. 3.815.787 and U.S. Pat. No. 8, as disclosed in No. 2.728.097 and No. 2.738.905. , which provides an arrangement for dispersing by mechanical action.

米国特許第３．８１５．７８７号に開示される散布器においてはピストンが円筒 状の容器の内面に形成された螺旋溝内に設置される。前記容器が散布器の頂部に 設置された放出部に対し相対回転された場合、ピストンは容器内で上方に位置す る放出体を放出するように上動せしめられる。しかしながら螺旋溝は容器内の放 出体に対し露呈しているから、放出体としての液体をバッグ内に収容して用いる 必要があり、バッグ内に収容しない場合放出体は放出前に螺旋溝に沿って漏出す ることになる。バッグが必要になると製造コストが増加し、且つバッグはピスト ンと螺旋溝あるいはピストンの放出方向に延びるタブを受容する垂直のガイドス ロットのいずれかの−との間で挟圧されて空になる危険が生じる。In the sprayer disclosed in U.S. Pat. No. 3,815,787, the piston is cylindrical. It is installed in a spiral groove formed on the inner surface of a shaped container. The container is placed on top of the sprayer. When rotated relative to the installed discharge part, the piston will be located upwards in the container. is moved upward to emit an emitter. However, the spiral groove Since the liquid is exposed to the discharge body, it is used by storing the liquid as the discharge body in a bag. If necessary and not housed in a bag, the emitter will leak out along the spiral groove before being released. That will happen. If a bag is required, manufacturing costs will increase, and the bag will be a vertical guide shaft that receives a helical groove or tab extending in the direction of ejection of the piston; There is a risk that the lot will be squeezed between the lot and the lot and become empty.

米国特許第３．１９５．１８８号に開示される散布器には軸方向に延びるネジ付 ロッドが具備され、このネジ付ロッドが容器内で軸方向に延び且つネジ付フォロ アーに装着される。ピストンはネジ付フォロアーの上位に配設され、容器内面と の間に密封構成がとられている。ネジ付ロッドは容器の底部に設置されたノブ手 段により回転される。ネジ付７オロアーとピストンとの間に配設されたスプリン グによりエネルギが蓄積されるべくネジ付フォロアーからピストンに動作が伝達 される。The spreader disclosed in U.S. Pat. No. 3,195,188 has an axially extending thread. A rod is provided, the threaded rod extending axially within the container and having a threaded follower. It is attached to the ar. The piston is placed above the threaded follower and is connected to the inner surface of the container. A sealed configuration is provided between the two. The threaded rod has a knob hand installed at the bottom of the container. Rotated by stages. Spring installed between threaded 7 lower and piston Motion is transmitted from the threaded follower to the piston so that energy is stored by be done.

ネジ付漏出ロッドが回転するとネジ付７オロアー並びにピストンによって放出体 が放出されるように作動される。一方ネジ付フォロアーの回転を阻止するため、 ネジ付フォロアーと容器の壁とはその断面において互いに相補的な非弧状形に形 成される。このようにネジ付フォロアーと容器の壁とを非弧状形にすることによ り、容器の内部容積が減少し、且つ容器内に収容される放出体の量も減少するこ とになる。また別の作動ロッド並びに回転ノブが必要になり、コストが増大し且 つ装置を構成するアセンブリも複雑になる。これと共にスプリングによりエネル ギの蓄積が顕著に行われるが、所望に応じてピストンの作動領域を横切るエネル ギの伝達が均一に行われず、スプレーパターンが最適状態に至らない。When the threaded leakage rod rotates, the ejector is released by the threaded 7-orer and the piston. is activated so that it is released. On the other hand, in order to prevent the rotation of the threaded follower, The threaded follower and the wall of the container have complementary non-arc shapes in their cross sections. will be accomplished. In this way, by making the threaded follower and the wall of the container into a non-arc shape, As a result, the internal volume of the container is reduced, and the amount of emitter contained within the container is also reduced. It becomes. Additionally, a separate actuation rod and rotary knob are required, increasing cost and The assembly that makes up the device also becomes complex. Along with this, energy is supplied by the spring. Although the accumulation of energy is significant, the energy across the working area of the piston is reduced as desired. Spray pattern is not optimal due to uneven energy transfer.

米国特許第１．７６２．９４３号に歯磨きペーストのような粘性材料用の散布器 が開示される。この散布器にはシリンダ内に配設されたピストンシェルが具備さ れる。外部シェルが共回転し且つ共に長手方向に移動するようにピストンシェル に結合される。放出用の弁に向かって内側並びに外側のシェルを移動するようシ リンダの底部を切除する必要がある。このように作動させることには不都合があ り、且つ部材の配列上切除個所を出す要がある。U.S. Pat. No. 1,762,943 discloses a dispensing device for viscous materials such as toothpaste. will be disclosed. This spreader is equipped with a piston shell located inside a cylinder. It will be done. the piston shells such that the outer shells co-rotate and move longitudinally together; is combined with Simulate the movement of the inner and outer shells towards the discharge valve. It is necessary to cut out the bottom of the cylinder. There are disadvantages to operating this way. In addition, due to the arrangement of the members, it is necessary to find the cut points.

米国特許第２．７２８．０９７号並びに同第２．７３８．９０５号にはネジ付ロ ッドを必須とする散布器が示されているが、散布ピストンを通過して散布体が漏 出してしまう必要がある。U.S. Patent Nos. 2.728.097 and 2.738.905 include threaded rods. A spreader is shown that requires a spreader head, but the spreader body leaks past the spreader piston. I need to get it out.

従って相対的にローコストで組立が容易であり、且つ非大気汚染形の散布体とし て構成されることが望ましく、放出体をバッグ内に蓄積する構成を必要とせず、 仮にバッグを使用する場合破砕されるバッグの使用による損失を最小限にする。Therefore, it is relatively low cost, easy to assemble, and can be used as a non-air polluting dispersant. It is desirable that the emitter be configured as To minimize losses caused by the use of bags that would be crushed if used.

しかして高度に均一化されたスプレーパターンを与えて連続的に放出するように 駆動する蓄積可能に構成された散布器を好適に提供する。This allows for continuous delivery giving a highly uniform spray pattern. A driveable, accumulably configured spreader is advantageously provided.
