特許文献１の吐出キャップは、内容液を滴出させたいときと内容液を注出（流体を連続した流れとして取り出すことをいう。）したいときとの使い分けが困難であった。 The discharge cap in Patent Document 1 was difficult to distinguish between when it was desired to drip the liquid contents and when it was desired to pour out the liquid contents (meaning to take out a continuous flow of fluid).

本発明の第１の目的は、吐出筒から液体を滴出するモードと吐出筒から液体を注出させるモードとを使い分けることができる吐出キャップを提供することである。
本発明の第２の目的は、吐出筒から液体を滴出する操作と吐出筒から液体を注出させる操作とを簡単に切り替え可能な吐出キャップを提供することである。 A first object of the present invention is to provide a discharge cap that can be selectively used between a mode for dripping liquid from a discharge cylinder and a mode for pouring liquid from the discharge cylinder.
A second object of the present invention is to provide a discharge cap that can easily switch between an operation of dripping liquid from the discharge cylinder and an operation of pouring liquid from the discharge cylinder.

第１の手段は、液体収納用の容器体１００の口頸部１０２へ嵌着される装着筒６の上端に、挿通孔２４を有する頂壁２０を付設し、この頂壁から吐出筒２２を起立したキャップ本体４と、
前記頂壁２０に弾性支承手段４２を介して支承させた縦向きの加圧棒５０の先端側を、前記挿通孔２４に気密に挿入させ、前記弾性支承手段４２に押下げ用の押圧部４５を設けた操作部材４０と、
を具備しており、
前記押圧部４５への押込みにより加圧棒５０を下降させることが可能に設け、
かつ前記頂壁２０の上側には、加圧棒５０の長手方向の一部に設けた空気置換用孔５２を配置し、
この空気置換用孔５２が前記頂壁２０の下側へ露出する状態となるまで加圧棒５０を下降させることが可能に構成した。 The first means is a cap body 4 having a top wall 20 with an insertion hole 24 attached to the upper end of an attachment tube 6 that is fitted to a mouth and neck portion 102 of a liquid storage container 100, and a discharge tube 22 standing upright from the top wall;
an operating member 40 in which a tip end side of a vertical pressure rod 50 supported on the top wall 20 via an elastic support means 42 is airtightly inserted into the insertion hole 24, and a pressing portion 45 for pressing down is provided on the elastic support means 42;
It is equipped with
The pressure rod 50 can be lowered by being pushed into the pressing portion 45.
An air replacement hole 52 is provided on the upper side of the top wall 20 at a portion of the longitudinal direction of the pressure rod 50.
The pressure rod 50 is configured to be able to be lowered until the air replacement hole 52 is exposed below the top wall 20 .

本手段では、図１に示す如く、装着筒６の上端に付設した頂壁２０に挿通孔２４を穿設させたキャップ本体４と、前記頂壁２０に弾性支承手段４２を介して支承させた縦向きの加圧棒５０の先端側を前記挿通孔２４に気密に挿入させ、前記弾性支承手段４２に押下げ用の押圧部４５を設けた操作部材４０とを具備する。
また頂壁２０の上側には、前記加圧棒５０の長手方向の一部に設けた空気置換用孔５２を配置しており、空気置換用孔５２が前記頂壁２０の下側へ露出する状態となるまで加圧棒５０を下降させることが可能としている。
この構成では、まず図３（Ａ）に示すように、前記押圧部４５への押込み操作で、前記加圧棒５０を下降させることで、装着筒６と嵌着された容器体１００の内部を加圧され、収納液体を前記吐出筒２２から滴出させることができる。
また、図３（Ｂ）に示すように、前記空気置換用孔５２が前記頂壁２０の下側へ露出する状態となるまで加圧棒５０を下降させることにより、容器体１００を外部へ連通させ、容器体１００内の液体を吐出筒２２から注出させることが可能となる。
従って、吐出筒２２から液体を滴出するモードと、吐出筒２２から液体を注出するモードとを適宜使い分けることができる。 As shown in FIG. 1, this means comprises a cap body 4 having a top wall 20 attached to the upper end of a mounting tube 6 and an insertion hole 24 formed in the top wall 20, and an operating member 40 having a vertical pressure rod 50 supported on the top wall 20 via an elastic support means 42, the tip end of which is airtightly inserted into the insertion hole 24, and a pressing portion 45 for pressing down is provided on the elastic support means 42.
In addition, an air replacement hole 52 is provided on a portion of the longitudinal direction of the pressure rod 50 on the upper side of the top wall 20, and it is possible to lower the pressure rod 50 until the air replacement hole 52 is exposed on the underside of the top wall 20.
In this configuration, first, as shown in Figure 3 (A), by pushing the pressure rod 50 into the pressing portion 45, the inside of the container body 100 fitted into the mounting tube 6 is pressurized, and the stored liquid can be caused to drip out of the discharge tube 22.
Furthermore, as shown in FIG. 3(B), by lowering the pressure rod 50 until the air replacement hole 52 is exposed below the top wall 20, the container body 100 can be connected to the outside, and the liquid in the container body 100 can be poured out from the discharge tube 22.
Therefore, a mode in which liquid is dripped from the discharge tube 22 and a mode in which liquid is poured out from the discharge tube 22 can be appropriately used.

第２の手段は、第１の手段を有し、かつ前記空気置換用孔５２は前記加圧棒５０の上半部５０ａに形成されている。 The second means has the first means, and the air replacement hole 52 is formed in the upper half 50a of the pressure rod 50.

本手段では、図１に示すように、前記空気置換用孔５２は前記加圧棒５０の上半部５０ａに形成されている。
そして図３（Ａ）に示すように、押圧部４５と浅く押し込むときには、加圧棒５０の下半部５０ｂのみが前記頂壁２０の下方へ進入して、前記容器体１００の内部が加圧されるように設けた。これにより、吐出筒２２から液体が滴出される。
また図３（Ｂ）に示すように、押圧部４５を深く押し込むときには、加圧棒５０の上半部５０ａに設けた空気置換用孔５２が頂壁２０の下側に露出し、これにより、容器体１００の内部が空気置換用孔５２を介して外部に連通され、容器体１００内の液体が吐出筒２２を介して注出される。
この構造では、押圧部４５の押込みの程度により、注出操作と吐出操作とを容易に切り替えることができる。 In this embodiment, the air replacement hole 52 is formed in the upper half 50 a of the pressure rod 50 as shown in FIG.
3A, when the pressing portion 45 is pressed shallowly, only the lower half 50b of the pressure rod 50 enters below the top wall 20, so that the inside of the container body 100 is pressurized. This causes the liquid to drip out of the discharge tube 22.
Furthermore, as shown in FIG. 3(B), when the pressing portion 45 is pressed deeply, the air replacement hole 52 provided in the upper half 50a of the pressure rod 50 becomes exposed on the underside of the top wall 20, whereby the inside of the container body 100 is connected to the outside via the air replacement hole 52 and the liquid in the container body 100 is poured out via the discharge tube 22.
In this structure, the operation can be easily switched between a pouring operation and a dispensing operation depending on the degree to which the pressing portion 45 is pressed.

第３の手段は、第１の手段又は第２の手段を有し、かつ前記弾性支承手段４２を、前記頂壁２０の上面に下端部４３を組み付けた帽状弾性体に形成するとともに、この帽状弾性体の頂部４４の上面を前記押圧部４５とし、

The pressure rod 50 was suspended from the top 44 .

本手段では、図１に示す如く、前記弾性支承手段４２を、前記頂壁２０の上面に下端部４３を組み付けた帽状弾性体に形成している。
そして、この帽状弾性体の頂部４４の上面を前記押圧部４５とするとともに、頂部４４から前記加圧棒５０を垂設している。
この構造では、帽状弾性体が挿通孔２４を覆うので、挿通孔２４に埃などが付着する不都合を生じにくく、衛生的に使用できる。 In this means, as shown in FIG. 1, the elastic support means 42 is formed as a hat-shaped elastic body having a lower end portion 43 attached to the upper surface of the top wall 20.
The upper surface of the top portion 44 of this cap-shaped elastic body serves as the pressing portion 45, and the pressure rod 50 is suspended from the top portion 44.
In this structure, the cap-shaped elastic body covers the insertion hole 24, so that the inconvenience of dust or the like adhering to the insertion hole 24 is unlikely to occur, and the device can be used hygienically.

For ease of explanation, the right side of FIG. 1 will be referred to as the "rear", the left side of FIG. 1 as the "front", and the directions perpendicular to the paper surface as the "left and right".
The mounting cylinder 6 in the illustrated example is a double cylinder in which the upper ends of an outer cylinder portion 8 and an inner cylinder portion 10 are connected by an annular wall portion 12, but this structure can be modified as appropriate.
The mouth/neck portion 102 is sandwiched between the outer cylinder portion 8 and the inner cylinder portion 10. An engagement protrusion 9 for engaging with the mouth/neck portion 102 is provided on the lower inner surface of the outer cylinder portion 8.
An upper cover 30 is connected to the upper rear end of the mounting cylinder 6 via a hinge 28 .

本実施形態では、前記環状壁部１２の上面からは、上蓋３０側へ係合させるための蓋係合突部１４が立設されている。
図示例では、前記蓋係合突部１４は、背面側（後面側）に切り欠き部ｎを残して平面視Ｃ字形の円弧状に形成されている。そして、前記切り欠き部ｎ内には複数の背面側突起１６が立設されている。
これらの構造を省略して、蓋係合突部１４を環状に形成しても構わない。
また図示例では、吐出キャップを分別廃棄するのに適した、公知の縦方向引き裂きラインＬ１及び周方向引き裂きラインＬ２が形成されている。縦方向引き裂きラインＬ１は、図２に示す如く、外筒部８の外面に縦設された平面視略Ｖ字形の外周切込み部ｃの内端側の薄肉部として形成されている。また周方向引き裂きラインＬ２は、図２に示す開蓋状態から上蓋３０を側外方に引っ張ることにより、縦方向引き裂きラインＬ１と連続して周方向へ破断するように形成されている。図示例において、外筒部８の上端面から穿設したスリット溝１８の下面内端の薄肉部、及び、外筒部８と環状壁部１２との間の薄肉部は、周方向引き裂きラインＬ２の一部である。これら縦方向引き裂きライン及び周方向引き裂きラインの構造は省略しても構わない。
また前記外筒部８の上部には、前半側に、図２に示すように、ほぼ１８０°の円弧範囲で平面視円弧状に外周から凹設された段凹部１７が設けられている。この段凹部１７に対して、上蓋３０側から突設する後述の被覆壁３５が近接し（図１参照）、或いは当接するように設けられている。これらの構造は適宜変更することができる。 In this embodiment, a lid engaging projection 14 for engaging with an upper lid 30 is provided upright on the upper surface of the annular wall portion 12 .
In the illustrated example, the cover engagement protrusion 14 is formed in a C-shaped arc shape in a plan view with a notch n left on the back side (rear side). A plurality of rear side protrusions 16 are provided upright within the notch n.
These structures may be omitted and the lid engaging projection 14 may be formed in an annular shape.
In the illustrated example, known vertical tear lines L1 and circumferential tear lines L2 suitable for separating and disposing of the discharge cap are formed. The vertical tear lines L1 are formed as thin-walled portions on the inner end side of the outer peripheral cut portions c that are generally V-shaped in plan view and vertically provided on the outer surface of the outer tube portion 8, as shown in FIG. 2. The circumferential tear lines L2 are formed so as to be broken in the circumferential direction in continuation with the vertical tear lines L1 by pulling the upper cover 30 outward from the open state shown in FIG. 2. In the illustrated example, the thin-walled portions at the inner end of the lower surface of the slit groove 18 drilled from the upper end surface of the outer tube portion 8 and the thin-walled portion between the outer tube portion 8 and the annular wall portion 12 are part of the circumferential tear lines L2. The structures of these vertical tear lines and circumferential tear lines may be omitted.

A cover wall 35 (described below) protruding from the upper cover 30 is provided adjacent to or in contact with this stepped recess 17 (see FIG. 1). These structures can be modified as appropriate.

本発明において、前記頂壁２０の適所、図示例では頂壁２０の後半部分（吐出筒２２とヒンジ２８との間の部分）には、挿通孔２４及び嵌合溝２６が形成されている。
前記挿通孔２４は、後述の加圧棒５０を挿入するための透孔である。
前記嵌合溝２６は、後述の帽状弾性体４２の下端部４３を嵌着させるための上面開口の凹溝であり、図示例では、前記挿通孔２４を中心とする円形状に形成されている。 In the present invention, an insertion hole 24 and a fitting groove 26 are formed in an appropriate position on the top wall 20, in the illustrated example, in the rear half portion of the top wall 20 (the portion between the discharge tube 22 and the hinge 28).
The insertion hole 24 is a through hole for inserting a pressure rod 50, which will be described later.
The fitting groove 26 is a concave groove that opens onto the upper surface into which a lower end portion 43 of a cap-shaped elastic body 42 (described later) is fitted, and in the illustrated example, is formed in a circular shape with the insertion hole 24 as its center.

上蓋３０は、キャップ本体４にヒンジ２８を介して連結された側周壁（蓋周壁）３２と、この側周壁３２の上端に付設された天板３７とを有している。そして、この天板３７からは、前記吐出筒２２内へ嵌挿された密閉筒３８が垂設されている。
図示例では、前記側周壁３２の下端部内周に、前記蓋係合突部１４の外面と係合して閉蓋状態を維持する係合凹部３３が周設されている。
また前記側周壁３２の内面には、図１に示す如く、前記係合凹部３３の上方に位置させて、前記蓋係合突部１４の内面に係止する複数の係合凸片３４が付設されている。
また前記側周壁３２の前部からは摘み部３６が前方へ突設されている。
さらに前記側周壁３２の下面からは、前記段凹部１７に対応した円弧状の被覆壁３５が垂設されている。
好適な図示例では、前記天板３７から後述の通気孔４７に近接させて、閉塞棒３９を垂設している。この閉塞棒３９は、上蓋３０の閉蓋時に前記通気孔４７を閉塞するように設けられており、これにより、後述の加圧棒５０などに付着した内容液が後述の空気置換孔５２内から通気孔４７を経て漏れ出すことを防止する。 The upper lid 30 has a side wall (lid wall) 32 connected to the cap body 4 via a hinge 28, and a top plate 37 attached to the upper end of the side wall 32. A sealing tube 38 is suspended from the top plate 37 and inserted into the discharge tube 22.
In the illustrated example, an engagement recess 33 is provided around the inner periphery of the lower end of the side peripheral wall 32, which engages with the outer surface of the lid engagement protrusion 14 to maintain the lid in the closed state.
1, a plurality of engaging protrusions 34 are provided on the inner surface of the side peripheral wall 32, positioned above the engaging recesses 33, for engaging with the inner surface of the lid engaging projection 14. As shown in FIG.
A knob 36 protrudes forward from the front portion of the side peripheral wall 32 .
Furthermore, an arc-shaped covering wall 35 corresponding to the stepped recess 17 is vertically extended from the lower surface of the side peripheral wall 32 .
In the preferred illustrated example, a blocking rod 39 is suspended from the top plate 37 in the vicinity of a vent hole 47 described below. This blocking rod 39 is provided so as to block the vent hole 47 when the top cover 30 is closed, thereby preventing the liquid contents adhering to a pressure rod 50 described below, etc., from leaking out through the vent hole 47 from an air replacement hole 52 described below.

操作部材４０は、前記頂壁２０に取り付けられた弾性支承手段４２と、弾性支承手段４２を介して昇降可能に支承された加圧棒５０とを有する。
前記弾性支承手段４２は、本実施形態において、前記嵌合溝２６内に嵌着させた厚肉の下端部４３を有する帽状弾性体として形成されている。
図示例の帽状弾性体４２の頂部４４は、平坦に近い上向きの凸状曲壁部であり、この頂部４４の上面を押圧部４５としている。もっとも、帽状弾性体４２の形状は適宜変更することができ、例えば半球状のもの（弾性ドーム）であっても構わない。
前記帽状弾性体４２の構造では、挿通孔２４の上方を覆うことができるので、挿通孔２４付近に埃などが付着しないなどの利点がある。
もっとも、弾性支承手段４２は、加圧棒５０を昇降可能に支承できればどのような形状でも構わない。
前記弾性支承手段４２の頂部４４から前記加圧棒５０が一体的に垂設されている。
前記加圧棒５０は、前記挿通孔２４内へ気密に嵌入されており、前記押圧部４５の押下げにより、図３（Ａ）に示すように、挿通孔２４内を下降し、押下げ力を解放することで、上昇して原位置に復帰するように設けている。加圧棒５０の機能は、前記押下げ操作により容器体１００の内部を加圧し、吐出筒２２からの液体の滴出（滴下）を促すことである。
押圧部４５が押し下げられていない状態（図１の状態）では、加圧棒５０の下半部５０ｂが前記挿通孔２４内に嵌合されている。
また加圧棒５０の上半部５０ａには空気置換用孔５２が設けられている。この空気置換用孔５２は、図１の状態で前記頂壁２０の上側に配置されている。
空気置換用孔５２は、容器体内の液体と置換する外気の導入路であり、本実施形態において、図１に示す如く、加圧棒５０の表面に凹設された連通凹部５３と、この連通凹部５３の適所（図示例では上部）と連続させて、加圧棒５０の上半部５０ａの中心部に穿設させた縦向きの連通路５４とで形成している。この連通路５４の上端は前記頂部４４に開口させた通気孔４７と連続している。
図示例において、連通凹部５３は空気置換用孔５２の下流側開口部としての役割を有する。
こうすることにより、図３（Ｂ）に示す如く、空気置換用孔５２の下流側開口部５３が前記頂壁２０の下側に露出する状態となるまで加圧棒５０を下降させると、空気置換用孔５２を介して外気が容器体１００内へ入る。これにより、容器体１００内の液体を、吐出筒２２を介して注出することができる。
なお、図示例では、前記連通凹部５３は、前記頂壁２０の厚みｄより大きい上下幅ｗを有しており、この連通凹部５３が図３（Ｂ）に示す状態で前記頂壁２０の上下両側に亘って頂壁２０の上側と下側とを連通させている。
この場合、前記連通路５４を省略して、前記連通凹部５３と弾性支承手段４２の適所に設けた通気孔とで外気導入路を形成しても構わない。
なお、図示例では、帽状弾性体４２の頂部４４に、図２に示す如く、前記通気孔４７から放射状（図示例では十字状）に延びる複数の補助空気溝４８を設け、これら通気孔４７と補助空気溝４８とで通気口４６を形成している。
これにより、図３（Ｂ）に示す如く、押圧部４５を指で押した状態で前記連通路５４が塞がることを回避できる。 The operating member 40 has an elastic support means 42 attached to the top wall 20 and a pressure rod 50 supported via the elastic support means 42 so as to be movable up and down.
In this embodiment, the elastic support means 42 is formed as a hat-shaped elastic body having a thick lower end portion 43 fitted into the fitting groove 26 .
The top 44 of the hat-shaped elastic body 42 in the illustrated example is a nearly flat, upwardly convex curved wall portion, and the upper surface of this top 44 serves as a pressing portion 45. However, the shape of the hat-shaped elastic body 42 can be appropriately changed, and may be, for example, a hemispherical one (elastic dome).
The structure of the hat-shaped elastic body 42 has an advantage that the upper part of the insertion hole 24 can be covered, so that dust and the like do not adhere to the vicinity of the insertion hole 24 .
However, the elastic support means 42 may have any shape as long as it can support the pressure rod 50 so that it can be raised and lowered.
The pressure rod 50 is integrally attached downward from the top 44 of the elastic support means 42 .
The pressure rod 50 is airtightly fitted into the insertion hole 24, and is arranged so that when the pressing portion 45 is pressed down, it descends inside the insertion hole 24 as shown in Fig. 3(A) and when the pressing force is released, it rises and returns to its original position. The function of the pressure rod 50 is to pressurize the inside of the container body 100 by the pressing operation, and to promote the dripping (dripping) of liquid from the discharge tube 22.
When the pressing portion 45 is not pressed down (the state shown in FIG. 1), the lower half portion 50 b of the pressure rod 50 is fitted into the insertion hole 24 .
An air replacement hole 52 is provided in the upper half 50a of the pressure rod 50. This air replacement hole 52 is disposed on the upper side of the top wall 20 in the state shown in FIG.
1, the air replacement hole 52 is an introduction path for outside air to replace the liquid in the container body, and in this embodiment, as shown in Fig. 1, it is formed by a communication recess 53 recessed into the surface of the pressure rod 50 and a vertical communication passage 54 drilled in the center of the upper half 50a of the pressure rod 50, connecting with an appropriate position (the upper part in the illustrated example) of this communication recess 53. The upper end of this communication passage 54 is connected to the air vent 47 opening in the top 44.
In the illustrated example, the communication recess 53 serves as a downstream opening of the air replacement hole 52 .
3(B), when the pressure rod 50 is lowered until the downstream opening 53 of the air replacement hole 52 is exposed on the underside of the top wall 20, outside air enters the container body 100 through the air replacement hole 52. This allows the liquid in the container body 100 to be poured out through the discharge tube 22.
In the illustrated example, the communicating recess 53 has an upper-lower width w that is greater than the thickness d of the top wall 20, and this communicating recess 53 connects the upper and lower sides of the top wall 20 over both the upper and lower sides of the top wall 20 in the state shown in Figure 3 (B).
In this case, the communication passage 54 may be omitted, and an outside air introduction passage may be formed by the communication recess 53 and an air hole provided at an appropriate position of the elastic support means 42.
In the illustrated example, as shown in FIG. 2, a plurality of auxiliary air grooves 48 extending radially (in the illustrated example, cross-shaped) from the air vent 47 are provided in the top 44 of the hat-shaped elastic body 42, and these air vents 47 and the auxiliary air grooves 48 form the air vent 46.
This makes it possible to prevent the communication passage 54 from being blocked when the pressing portion 45 is pressed with a finger, as shown in FIG. 3B.

前記構成において、図１に想像線で示すように、本発明の吐出キャップ２と容器体１００の口頸部１０２に取り付けた後、上蓋３０を開蓋して、容器体１００を前方へ傾けた状態で、図３（Ａ）に示すように、前記空気置換用孔５２が頂壁２０の下側に露出しない範囲で、押圧部４５を浅く押し込むと、加圧棒５０が容器体１００側へ進入することにより、容器体１００内が加圧され、これにより、吐出筒２２から液体が滴下される。
また、図３（Ｂ）に示すように押圧部４５を深く押し込むと、前記空気置換用孔５２が頂壁２０の下方へ露出し、外気が空気置換用孔５２を介して容器体１００内へ流入する。これにより、吐出筒２２から液体が注出される。
故に液体を滴出するモード及び注出するモードを適切に使い分けることができる。そして、これらの使用モードの切り替えは、単に押圧部４５の押込み量を加減すればよいから、滴出操作と注出操作とを簡単に切り替えることができる。
なお、図１に示す閉蓋状態において、操作部材４０をヒンジ２８及び吐出筒２２の間にスペースに配置されているから、このスペースを有効利用して、前記操作部材４０を上蓋３０の内部にコンパクトに組み込むことができる。 In the above configuration, as shown by imaginary lines in FIG. 1 , after attaching the discharge cap 2 of the present invention to the mouth and neck portion 102 of the container body 100, the top lid 30 is opened and the container body 100 is tilted forward. Then, as shown in FIG. 3 (A), when the pressing portion 45 is pressed shallowly within a range where the air replacement hole 52 is not exposed on the underside of the top wall 20, the pressure rod 50 enters the container body 100, pressurizing the inside of the container body 100, and liquid is thereby dripped from the discharge tube 22.
3(B), when the pressing portion 45 is pressed deeply, the air replacement hole 52 is exposed below the top wall 20, and outside air flows into the container body 100 through the air replacement hole 52. This causes the liquid to be poured out of the discharge tube 22.
Therefore, the mode for dripping liquid and the mode for pouring liquid can be appropriately used. Moreover, the mode can be switched between these modes by simply adjusting the amount of pressing of the pressing portion 45, so that the dripping operation and the pouring operation can be easily switched.
In addition, in the closed state shown in Figure 1, the operating member 40 is disposed in the space between the hinge 28 and the discharge tube 22, so that this space can be effectively utilized to compactly incorporate the operating member 40 inside the top cover 30.

次に本発明の実施形態による効果を説明する。
全ての態様に共通する事柄として、キャップ本体４の頂壁２０に対して弾性支承手段４２を介して支承させた縦向きの加圧棒５０の先端側を、前記挿通孔２４に気密に挿入させ、前記弾性支承手段４２に押下げ用の押圧部４５を設け、前記押圧部４５への押込みにより、前記加圧棒５０を下降させることが可能に設け、前記頂壁２０の上側には、加圧棒５０の長手方向の一部に設けた空気置換用孔５２を配置し、この空気置換用孔５２が頂壁２０の下側へ露出する状態となるまで加圧棒５０を下降させることが可能に設けた態様では、液体が滴出されるモードと、液体が注出されるモードとを、適宜使い分けることができる。
また、前記空気置換用孔５２を前記加圧棒５０の上半部５０ａに形成した態様では、押圧部４５を浅く押し込むことで液体を滴出させ、また押圧部４５を深く押し込むことで液体を注出させることができるので、単に押圧部４５の押込みの程度を切り替えることで液体の滴出操作と注出操作とを簡単に切り替えることができる。
また、前記弾性支承手段４２を、前記頂壁２０の上面に下端部４３を組み付けた帽状弾性体に形成し、帽状弾性体の頂部４４から前記加圧棒５０を垂設した態様では、帽状弾性体が挿通孔２４を覆うので、挿通孔２４に埃などが付着する不都合を生じにくい。
また、有頂筒状の上蓋３０を前記装着筒６の上端側にヒンジ２８を介して連結させ、このヒンジ２８及び吐出筒２２の間に、前記挿通孔２４及び操作部材４０を配置させた態様では、前記上蓋３０の内側に前記操作部材４０をコンパクトに組み込むことができる。 Next, effects of the embodiment of the present invention will be described.
A common feature of all the aspects is that the tip side of a vertical pressure rod 50 supported against the top wall 20 of the cap body 4 via elastic support means 42 is airtightly inserted into the insertion hole 24, the elastic support means 42 is provided with a pressing portion 45 for pressing down, the pressure rod 50 can be lowered by pressing into the pressing portion 45, an air replacement hole 52 is provided on a part of the longitudinal direction of the pressure rod 50 on the upper side of the top wall 20, and the pressure rod 50 can be lowered until this air replacement hole 52 is exposed on the underside of the top wall 20, so that a mode in which liquid is dripped and a mode in which liquid is poured can be used appropriately.
Furthermore, in an embodiment in which the air replacement hole 52 is formed in the upper half 50a of the pressure rod 50, the liquid can be dripped by pressing the pressing portion 45 shallowly, and the liquid can be poured out by pressing the pressing portion 45 deeply. Therefore, by simply changing the degree to which the pressing portion 45 is pressed, it is possible to easily switch between the dripping operation and the pouring operation of the liquid.
Furthermore, in an embodiment in which the elastic support means 42 is formed as a hat-shaped elastic body having a lower end 43 attached to the upper surface of the top wall 20, and the pressure rod 50 is suspended from the top 44 of the hat-shaped elastic body, the hat-shaped elastic body covers the insertion hole 24, so that the inconvenience of dust and the like accumulating in the insertion hole 24 is less likely to occur.
In addition, in an embodiment in which a topped cylindrical top cover 30 is connected to the upper end of the mounting tube 6 via a hinge 28, and the insertion hole 24 and operating member 40 are arranged between this hinge 28 and the discharge tube 22, the operating member 40 can be compactly incorporated inside the top cover 30.
