ポンプの押下げヘッドとして、上方付勢状態で押し下げ可能に突出したステムの上端に嵌着するとともに、側方へ突出したノズル筒内とステム内とを結ぶ流路を備え、押下げヘッドを上下動させることで、装着した容器体内の液を吸い上げて吐出する如く構成したものが知られている。また、これ等ポンプの押下げヘッドでノズル筒内の液の乾燥防止を図ったものが提案されている。（例えば、特許文献１参照）   As the pump's push-down head, it is fitted to the upper end of the stem that can be pushed down in the upward biased state, and has a flow path that connects the inside of the nozzle cylinder and the stem that protrudes to the side. It is known that the liquid in the mounted container is sucked up and discharged by being moved. In addition, there has been proposed a pump head for preventing the liquid in the nozzle cylinder from being dried. (For example, see Patent Document 1)

上記押下げヘッドはノズル筒の先端開口を、ノズル筒の先端面に回動して開閉可能に閉塞する開閉蓋を備えている。これにより、不使用時に蓋を閉じておけばノズル筒内に液の詰まりが発生することを防止でき、その結果、液の飛び散りや吐出不良等の不都合を防止できるという特有の効果を発揮する。
特開２００５−１５３９８４号公報 The push-down head includes an opening / closing lid that closes the opening at the tip of the nozzle cylinder so as to be able to open and close by rotating to the tip surface of the nozzle cylinder. Accordingly, if the lid is closed when not in use, it is possible to prevent clogging of the liquid in the nozzle cylinder, and as a result, a unique effect of preventing inconveniences such as liquid splattering and ejection failure is exhibited.
JP 2005-153984 A

本発明は上記した如きノズル筒内の液の固化による詰まりを防止でき、しかも、特別の操作を行わなくても常時はノズル筒内の乾燥防止，液の固化防止を行え、また、そのままの状態で液の吐出を行え、更に、吐出後はまた元の乾燥防止状態に切り替わり、取り扱いが極めて容易である利点も兼ね備えたポンプの押下げヘッドを提案する。更に、構造は簡単で容易に製造が可能な利点を兼ね備えたポンプの押下げヘッドを提案する。   The present invention can prevent clogging due to the solidification of the liquid in the nozzle cylinder as described above, and can always prevent the drying in the nozzle cylinder and prevent the liquid from solidifying without any special operation. In addition, the present invention proposes a pump press-down head that can discharge the liquid and then switches to the original dry-prevented state after the discharge and has the advantage of being extremely easy to handle. Furthermore, a pump pressing head having the advantage of simple structure and easy manufacturing is proposed.

第１の手段として、以下の通り構成した。即ち、上方付勢状態で押し下げ可能に突出したステム３の上端に嵌着するとともに、側方へ突出したノズル筒A3内とステム３内とを結ぶ流路ｐを備えてなるポンプの押下げヘッドであって、ノズル筒A3を柔軟で弾力性に富む材質で形成するとともに、ノズル筒A3内先端部に玉状のシール材A4を嵌合させてその内外を遮断し、シール材A4のノズル筒A3からの抜け出しを防止する抜け出し防止機構を設け、該抜け出し防止機構を、ノズル筒A 3 内面に掛け渡してシール材A 4 の外側面を係止する外部ストッパー31と、ノズル筒A 3 内面より周方向間隔をあけて複数突設し且つシール材A 4 の内側周縁部に係合する内部ストッパー32とで構成し、吐出時の液圧でノズル筒A3を拡開させてシール材A4とノズル筒A3内面との隙間ｄを介して液を吐出することを特徴とするポンプの押下げヘッド。 The first means is configured as follows. That is, the pump is pushed down by being fitted to the upper end of the stem 3 projecting so as to be able to be pushed down in the upward biased state, and having a flow path p connecting the inside of the nozzle cylinder A 3 projecting sideways and the inside of the stem 3. The nozzle cylinder A 3 is made of a flexible and elastic material, and a ball-shaped sealing material A 4 is fitted to the inner end of the nozzle cylinder A 3 to block the inside and the outside. An external stopper 31 is provided that prevents the A 4 from coming out of the nozzle cylinder A 3 , and that extends over the inner surface of the nozzle cylinder A 3 to lock the outer surface of the sealing material A 4 . The nozzle cylinder A 3 is composed of multiple internal stoppers 32 that protrude from the inner surface of the nozzle cylinder A 3 at intervals in the circumferential direction and engage with the inner peripheral edge of the sealing material A 4. The nozzle cylinder A 3 is expanded by the hydraulic pressure during discharge. The liquid is discharged through a gap d between the sealing material A 4 and the inner surface of the nozzle cylinder A 3. And pump pressing head.

本発明ではノズル筒A3内先端部に塊状のシール材A4を嵌合させてその内外を遮断しているので、不使用時はノズル筒A3内外を確実に遮断してノズル筒A3内の液の固化の防止を図ることができ、その結果、ノズル筒A3内の目詰まり、液の吐出不良等の不都合を確実に防止することができる。また、液の吐出に当たっては、押下げヘッドを上下動させるという通常操作により行えるため、その取り扱い操作も容易である。また、その構造も極めて簡単であるため容易に製造できる利点も兼ね備える。 Since the present invention shuts off the inside and outside of the sealing member A 4 of the lump is fitted within the distal end nozzle tube A 3, when not in use the nozzle tube A 3 is reliably cut off the nozzle tube A 3 out it is possible to prevent solidification of the liquid of the inner, so that the clogging in the nozzle tube a 3, it is possible to reliably prevent the disadvantage of ejection failure or the like of the liquid. Further, since the liquid can be discharged by a normal operation of moving the pressing head up and down, the handling operation is also easy. Moreover, since the structure is also very simple, it has the advantage that it can be manufactured easily.

シール材A4が玉状である場合には、シール材A4の内側面周縁部が外方へ弯曲しているためノズル筒A3を広げる方向に液圧がかかり易く、また、内外遮断時のノズル筒A3とシール材A4との接触面積が小さいため、円滑なノズル筒A3の拡開を行える利点がある。 When the sealing material A 4 is ball-shaped, the inner peripheral edge of the sealing material A 4 is bent outward, so that it is easy to apply hydraulic pressure in the direction of expanding the nozzle tube A 3 and when the inner and outer are cut off. Since the contact area between the nozzle cylinder A 3 and the sealing material A 4 is small, there is an advantage that the nozzle cylinder A 3 can be smoothly expanded.

上記抜け出し防止機構を、ノズル筒A3内面に掛け渡してシール材A4の外側面を係止する外部ストッパー31と、ノズル筒A3内面より周方向間隔をあけて複数突設し且つシール材A4の内側周縁部に係合する内部ストッパー32とで構成した場合には、液圧でシール材A4がノズル筒A3先端から抜け出してしまうという不都合を確実に防止でき、また、内部ストッパー32の間隙からシール材A4とノズル筒A3との隙間ｄへの液の供給が可能で円滑な液の吐出が可能となる。 The escape preventing mechanism, an external stopper 31 for locking the outer surface of the seal member A 4 spanned the nozzle tube A 3 inner surface, a plurality projecting to and sealing material at an circumferential spacing from the nozzle tube A 3 inner surface when configured in the internal stopper 32 which engages the inner perimeter of a 4 can reliably prevent the disadvantage that the sealing material a 4 hydraulically will come out of the nozzle cylinder a 3 tip, the internal stopper The liquid can be supplied from the gap 32 to the gap d between the sealing material A 4 and the nozzle cylinder A 3, and the liquid can be smoothly discharged.

As the elastomer, a thermoplastic type or a crosslinked type such as a natural rubber or a synthetic rubber vulcanizate can be used. Further, a cylindrical shape having an open front and rear ends, and an inner periphery fixedly fitted to the fitting portion 30 to the distal end connecting tube portion 23 the outer periphery of the connecting member A 2 of the base end portion of the large diameter. Further, the internal tip fitted to the sealing member A 4 beaded, with an external stopper 31 abuts the outer surface of the sealing material A 4, and an internal stopper 32 abuts on the inner periphery of the sealing member A 4 Provided. The outer stopper 31 has a belt-like shape in which the inner surface of the nozzle cylinder A 3 is vertically cut and spanned, and the inner stopper 32 has a ridge shape in which a plurality of protrusions are provided on the inner surface of the nozzle cylinder A 3 at equal intervals in the circumferential direction. The external stopper 31 and the internal stopper 32 constitute a slip-out preventing means for preventing the seal material A 4 from slipping out of the nozzle cylinder A 3 in and out.

尚、外部ストッパー31として、本例の如く一本の帯状に掛け渡したものに限らず、例えば、中心から放射状に掛け渡した形態のものであっても良く、或いはノズル筒A3内面を横断して掛け渡すものであっても良く、その数も一本でも複数本であっても良い。また、内部ストッパー32は，周方向複数突設した突部形態のものであっても良く。また、環状の突部形態のものであっても良い。また、前者の場合必ず等間隔に設ける必要もない。図７乃至９は図１の例に於ける外部ストッパー31の他の例を示すもので、図７は中心から三方向放射状に帯状部を延設した外部ストッパー31であり、図８は中心の円形部から三方向放射状に帯状部を延設した外部ストッパー31であり、図９は中心の円形部から四方向放射状に帯状部を延設した外部ストッパー31である。 Note that cross the external stopper 31 is not limited to that spanned the single band-shaped as in the present embodiment, for example, may be one of the transfer form over radially from the center, or a nozzle tube A 3 inner surface And the number may be one or more. Further, the internal stopper 32 may be a protrusion having a plurality of protrusions in the circumferential direction. Moreover, the thing of a cyclic | annular protrusion form may be sufficient. In the former case, it is not always necessary to provide them at regular intervals. FIGS. 7 to 9 show other examples of the external stopper 31 in the example of FIG. 1. FIG. 7 shows the external stopper 31 with strips extending in three directions radially from the center, and FIG. FIG. 9 shows an external stopper 31 in which strips extend radially from a circular portion in three directions, and FIG. 9 shows an external stopper 31 in which strips extend radially in four directions from a central circular portion.

シール材A4は合成樹脂或いは金属等により形成された玉状をなし、周縁部をノズル筒A3内周に密接させて、その上流及び下流を液密に遮断している。 The sealing material A 4 is formed in a ball shape made of synthetic resin, metal, or the like, the peripheral edge portion is brought into close contact with the inner periphery of the nozzle cylinder A 3 , and the upstream and downstream sides thereof are liquid-tightly blocked.

この様に構成される押下げヘッドＡは、ステム３内から縦筒10内を通り、横筒14内から先端連結筒部23内を介してノズル筒A3内に至る流路ｐを備えている。そして、常時は図２及び図３に拡大図で示す如く、シール材A4の周縁部がノズル筒A3内周面に密接してその内外を遮断している。この際、シール材A4外側面には外部ストッパー31が当接係止しており、また、シール材A4内側周縁部には内部ストッパー32が当接係止した状態にある。 Pressing heads A configured in this manner, through the vertical cylinder 10 from the inside of the stem 3, provided with a flow path p reaching the nozzle cylinder A 3 from the horizontal cylinder inside 14 through the distal end connecting tube portion 23 Yes. And, normally, as shown in enlarged view in Figures 2 and 3, the peripheral portion of the sealing member A 4 is cut off the inner and outer closely the third inner peripheral surface nozzle tube A. At this time, the sealing material A 4 outer surface outside the stopper 31 is sealed abutting engagement, also, the sealing material A 4 inner perimeter in a state where the internal stopper 32 is sealed abutment engagement.

図１の状態は押下げヘッドＡを押下げて螺着した状態であり、この状態から螺脱して押下げヘッドＡを上昇させて液の吐出が可能な状態とした後、押下げヘッドＡを押し下げると、図４に示す如く、ステム３内から流路ｐを介してノズル筒A3内に導入される液の液圧でシール材A4が押圧されるとともに、外部ストッパー31は外方へ弯曲変形される。この際、図５に示す如く、ノズル筒A3が膨張拡開し、シール材A4とノズル筒A3との隙間ｄから液が吐出される。 The state shown in FIG. 1 is a state where the press-down head A is pressed down and screwed. The screw is released from this state and the press-down head A is raised so that liquid can be discharged. When pushed down, as shown in FIG. 4, the sealing material A 4 is pressed by the liquid pressure introduced into the nozzle cylinder A 3 from the stem 3 through the flow path p, and the external stopper 31 is moved outward. The fold is transformed. At this time, as shown in FIG. 5, the nozzle cylinder A 3 expands and expands, and the liquid is discharged from the gap d between the sealing material A 4 and the nozzle cylinder A 3 .

次いで押下げヘッドＡの押圧を解除して、上方付勢力により押下げヘッドＡが上昇する際にはノズル筒A3及び外部ストッパー31の弾性復元力により元の状態に戻り、シール材A4によりその内外を遮断される。 Next, when the pressing head A is released by the upward biasing force when the pressing head A is released, it returns to its original state by the elastic restoring force of the nozzle cylinder A 3 and the external stopper 31, and the sealing material A 4 The inside and outside are shut off.

図６は他の例を示すもので、ノズル筒A3の本体部A1への固定手段を代えた例を示す。本例に於いて、横筒14を大径横筒13より若干短く構成し、また、ノズル筒A3の基端外周から外向きフランジ33を突設している。更に、連結部材A2は筒状をなし、一端縁部に内向きフランジ24を突設している。そして、ノズル筒A3の基端面を横筒14の先端面に当接し、横筒14と大径横筒13内に嵌合させた連結部材A2の内向きフランジ24をノズル筒A3の外向きフランジ33の外面に係合させてノズル筒A3のより確実な抜け出し防止を図っている。 FIG. 6 shows another example, and shows an example in which the means for fixing the nozzle tube A 3 to the main body A 1 is changed. In the present embodiment, the horizontal tube 14 is slightly shorter configuration than the atmospheric径横tube 13, also projecting outward flange 33 from the base end outer periphery of the nozzle tube A 3. Furthermore, the connecting member A 2 is a tubular shape, and projecting the inward flange 24 at one edge. Then, the base end surface of the nozzle cylinder A 3 is brought into contact with the distal end surface of the horizontal cylinder 14, and the inward flange 24 of the connecting member A 2 fitted into the horizontal cylinder 14 and the large-diameter horizontal cylinder 13 is connected to the nozzle cylinder A 3 thereby achieving more reliable escape prevention of the nozzle tube a 3 is engaged with the outer surface of the outward flange 33.

図10乃至図12は更に他の例を示し、少なくともシール材A4の嵌合部分から先方のノズル筒A3内面を先端に行くに従って窄む形状に形成するとともに、シール材A4の外周面をその窄み形状と同形状に形成し、ノズル筒A3内面より周方向間隔をあけて複数突設し且つシール材A4の内側周縁部に係合する内部ストッパー32を設けて抜け出し防止手段を構成した例を示す。 10 to 12 illustrates yet another example, as to form a mating portion of at least the sealing member A 4 in Subomu shape toward the tip end of the nozzle tube A 3 the inner surface of the other party, the outer peripheral surface of the sealing member A 4 the Subomi formed in the same shape, the nozzle tube a 3 inner surface than at an circumferential intervals plurality projected and sealing material a 4 in the inner perimeter prevention means exit provided inside stopper 32 which engages the The example which comprised is shown.

本例では、ノズル筒A3の先端部分を、上面が先端に行くに従って傾斜下降する四角筒状に形成している。また、この四角筒状部分の上辺を他の左右側辺、底辺と比較して薄肉な薄肉部34に形成して弾性変形が起こり易い様に構成している。この四角筒状部分に、周面がその内面にフィットする四角柱状のシール材A4を嵌合している。更に、図11に示す如く、シール材A4の外側面に当接する外部ストッパー31を、筒孔を横断して掛け渡し、また、シール材A4の内側周縁部に係合する突条形態の内部ストッパー32を、図12に示す如く、筒孔両側面及び下面にそれぞれ突設している。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。 In this example, the tip portion of the nozzle tube A 3, are formed in a square tubular shape inclined downward in accordance with the upper surface goes on the tip. Further, the upper side of the rectangular cylindrical portion is formed in a thin portion 34 that is thinner than the other left and right sides and the bottom side so that elastic deformation is likely to occur. A square pillar-shaped sealing material A 4 whose peripheral surface fits on the inner surface is fitted into this square cylindrical portion. Further, as shown in FIG. 11, an external stopper 31 that contacts the outer surface of the sealing material A 4 is extended across the cylindrical hole, and the protruding strip shape that engages with the inner peripheral edge of the sealing material A 4 is used. As shown in FIG. 12, internal stoppers 32 project from both side surfaces and the bottom surface of the cylindrical hole. The other configuration is the same as that of the example of FIG.

図10の状態の押下げヘッドＡを螺脱して上昇させた後、押下げヘッドＡを押し下げると、ステム３内から流路ｐを介してノズル筒A3内に導入される液の液圧でシール材A4が押圧されるとともに、外部ストッパー31は外方へ変形される。この際、ノズル筒A3の上辺が膨張拡開し、シール材A4上面とノズル筒A3との隙間ｄから液が吐出される。次いで押下げヘッドＡの押圧を解除して、上方付勢力により押下げヘッドＡが上昇する際にはノズル筒A3及び外部ストッパー31の弾性復元力により元の状態に戻り、シール材A4によりその内外を遮断される。 When the push-down head A in the state shown in FIG. 10 is screwed and raised and then pushed down, the pressure of the liquid introduced from the stem 3 into the nozzle cylinder A 3 through the flow path p is reduced. with the sealing member A 4 is pressed, the external stopper 31 is deformed outwardly. At this time, the upper side of the nozzle cylinder A 3 expands and expands, and the liquid is discharged from the gap d between the upper surface of the sealing material A 4 and the nozzle cylinder A 3 . Next, when the pressing head A is released by the upward biasing force when the pressing head A is released, it returns to its original state by the elastic restoring force of the nozzle cylinder A 3 and the external stopper 31, and the sealing material A 4 The inside and outside are shut off.

尚、少なくともシール材A4の嵌合部分から先方のノズル筒A3内面を先端に行くに従って窄む形状に形成するとともに、シール材A4の外周面をその窄み形状と同形状に形成するという構成としては、ノズル筒A3を横円錐台形状や横角錐台形状に形成することも可能であり、それに伴ってシール材A4も、その外面形状が同様のものを採用する。 Incidentally, as to form a mating portion of at least the sealing member A 4 in Subomu shape toward the tip end of the nozzle tube A 3 the inner surface of the other party, to form an outer peripheral surface of the sealing material A 4 in the Subomi the same shape In this configuration, the nozzle cylinder A 3 can be formed in a horizontal truncated cone shape or a horizontal truncated pyramid shape, and the sealing material A 4 having the same outer surface shape is adopted accordingly.
