Description

本発明は、内容物を一回で使い切る際に使用して好適な注出器に関するものであり、内容物の誤った注出あるいは不正な注出を確実に防止しようとするものである。   The present invention relates to a dispenser that is suitable for use when the contents are used up at once, and is intended to reliably prevent erroneous or unauthorized dispensing of the contents.

比較的粘度が高く流動性のないものを内容物とする化粧品等において使用される一回で使い切るカートリッジタイプの容器が数多く存在しており、通常は、シリンジ本体内に組み込まれたプランジャーに押し込み力を付加して該プランジャーをシリンジ本体内でスライドさせ、内容物をノズルから押し出すタイプの注出器が使用されている。   There are many cartridge-type containers that can be used up in one-time use, such as in cosmetics that contain relatively high viscosity and non-flowable contents, and are usually pushed into the plunger built into the syringe body. A type of dispenser is used in which force is applied to slide the plunger within the syringe body to push the contents out of the nozzle.

ところで、この種の注出器にあっては、プランジャーに不用意な力が加わり誤って内容物が注出されてしまったり、該プランジャーが意図的に押し込まれて内容物が注出されてしまう懸念があることから、その解決が試みられているところ、従来の注出器においては部品点数が増加するとともに構造の複雑化が避けられず効率的な製造が困難となるだけでなくサイズの大型化も避けられない状況にあった（例えば特許文献１参照）。   By the way, in this type of dispenser, an inadvertent force is applied to the plunger and the contents are accidentally dispensed, or the plunger is intentionally pushed and the contents are dispensed. In the conventional dispenser, the number of parts increases and the complexity of the structure is unavoidable and it is difficult to manufacture efficiently. It was inevitable to increase the size (see Patent Document 1, for example).

実公平６−３９８２７号公報No. 6-39827

本発明の課題は、内容物が誤って注出されたり、不正に注出されることのない構造の簡素化された注出器を提案するところにある。   An object of the present invention is to propose a simplified dispenser having a structure in which contents are not accidentally or illegally dispensed.

本発明は、内容物の充填空間を形成する筒体と、この充填空間内にてスライド可能に配置されたピストンと、前記筒体の先端部に配され、ピストンのスライドにて充填空間内の内容物を押圧して排出する注出口とを備えた注出器であって、
前記筒体の充填空間内に、前記筒体の末端部に保持され、前記充填空間内にて回動可能なスクリューロッドと、前記スクリューロッドにスライド可能に係合するとともに該スクリューロッドの回動に同期して前記ピストンを前記注出口へ向けて押圧するスリーブを設け、
前記筒体は、該筒体とは別体に設けられ、該筒体の末端部への差し込みによる前記スクリューロッドとの連係により前記スクリューロッドを回動させる回転体を有する、ことを特徴とする注出器である。 The present invention provides a cylindrical body that forms a filling space for contents, a piston that is slidably disposed in the filling space, and a tip of the cylindrical body. A dispenser comprising a spout for pressing and discharging the contents,
A screw rod held at the end of the cylinder in the filling space of the cylinder and rotatable in the filling space, and slidably engaged with the screw rod and rotating the screw rod A sleeve that presses the piston toward the spout in synchronization with,
The cylindrical body is provided separately from the cylindrical body, and includes a rotating body that rotates the screw rod by being linked with the screw rod by being inserted into a distal end portion of the cylindrical body. It is a dispenser.

上記の筒体としては、その末端部に、前記回転体の差し込みにおいて該回転体の外表面と該筒体の外表面が一致するような、面一（つらいち）の外表面を形成する段差面を設けるのが望ましい。   As the above-mentioned cylindrical body, a step that forms a flush outer surface at the end of the cylindrical body so that the outer surface of the rotating body coincides with the outer surface of the cylindrical body when the rotating body is inserted It is desirable to provide a surface.

回転体を筒体の末端部に差し込んで回動させることにより初めてピストンを動かすようにしたため、誤って内容物が注出されたり、不正に内容物が注出されるようなことはない。   Since the piston is moved for the first time by inserting the rotating body into the end of the cylinder and turning it, the contents are not accidentally poured out or the contents are not poured out illegally.

筒体の末端部に回転体を差し込んだのちにおいて該回転体の外表面と面一となる段差面を設けておくことにより注出器そのもの外観がすっきりとするため美観あるいは見栄えが損なわれることがない。回動体は、筒体の末端部において差し込んで使用するものであるためサイズの大型化（長大化）や構造の複雑化を招くこともない。   After inserting the rotating body into the end of the cylindrical body, by providing a stepped surface that is flush with the outer surface of the rotating body, the appearance of the dispenser itself is clean, so the appearance or appearance may be impaired. Absent. Since the rotating body is inserted and used at the end of the cylindrical body, there is no increase in size (lengthening) or complicated structure.
