Description

本発明は、ポンプ動作により容器本体の内容物を噴出させるにあたり発生する負圧を解消すべく、当該容器本体の胴部内側に、かかる負圧により内容物を押し上げつつ上昇する中皿を備えたポンプ付き容器に関するものである。   In order to eliminate the negative pressure generated when the contents of the container main body are ejected by the pump operation, the present invention is provided with an inner dish that rises while pushing up the contents by the negative pressure inside the trunk of the container main body. It relates to a container with a pump.

こうした従来のポンプ付き容器には、容器本体の胴部を不透明することにより内容物の残量が確認できない問題を解消すべく、中皿の背面に球形の固体を取り外し可能に設け、この固体を中皿が上死点に達したタイミングで容器本体の底部に落下させることにより、聴覚的に残量確認できるものが提案されている(例えば、特許文献1参照。)。

以下、図面を参照して、本発明の好適な形態を詳細に説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

図1は、本発明の第一の形態であるポンプ付き容器100の未使用状態を一部断面で示す側面図であり、図2は、同形態の内容物吐出完了直前の状態を一部断面で示す側面図である。また、図3は、同形態の使用済み状態を一部断面で示す側面図である。更に、図4(a)〜(c)はそれぞれ、後述の中皿140、それを構成するスライド部材141及び落下部材142を示す斜視図である。   FIG. 1 is a side view showing, in partial cross section, an unused state of a pump-equipped container 100 according to the first embodiment of the present invention, and FIG. 2 is a partial cross section showing a state immediately before completion of content discharge in the same form. It is a side view shown by. Moreover, FIG. 3 is a side view which shows the used state of the same form in a partial cross section. Further, FIGS. 4A to 4C are perspective views showing a middle plate 140, which will be described later, and a slide member 141 and a drop member 142 constituting the middle plate 140, respectively.

図面において、符号110は、内容物を充填する筒状の口部111aと当該口部111aの外側に同心配置される外装部111bとを有し当該口部111a及び外装部111bが肩部112を介して筒状の胴部113に繋がる容器本体である。容器本体110は、不透明な遮光性の色彩を有する合成樹脂からなり、口部111a、外装部111b、肩部112及び胴部113とを一体に構成する。   In the drawing, reference numeral 110 denotes a cylindrical mouth portion 111a for filling the contents and an exterior portion 111b concentrically arranged outside the mouth portion 111a, and the mouth portion 111a and the exterior portion 111b have shoulder portions 112. The container body is connected to the cylindrical body 113 via the tube body. The container body 110 is made of a synthetic resin having an opaque light-shielding color, and integrally includes a mouth portion 111a, an exterior portion 111b, a shoulder portion 112, and a trunk portion 113.

また、胴部113の口部111aと対向する下端には、外気導入孔hを有する透明又は半透明の底蓋部114が別体に取り付けられている。   In addition, a transparent or translucent bottom cover 114 having an outside air introduction hole h is attached to the lower end of the body 113 facing the mouth 111a.

符号120は、口部111aに装着され当該口部111aの内側から垂下するポンプである。また、符号130は、ポンプ120に繋がりその押下げ及び復帰の繰り返しにより当該ポンプ120を動作させて内容物を噴出するノズルヘッドである。   Reference numeral 120 denotes a pump that is attached to the mouth portion 111a and hangs down from the inside of the mouth portion 111a. Reference numeral 130 denotes a nozzle head that is connected to the pump 120 and operates the pump 120 by repeatedly pressing down and returning to eject the contents.

詳細には、ポンプ120は、口部111aに装着され当該口部111aの内側を垂下するシリンダ121を有する。シリンダ121は、口部111aの内外を着脱可能に挟持する装着筒部121aを有し、この装着筒部121aの外側には、口部111aと外装部111bとの相互間に形成された環状溝に嵌合し、その外側部分が外装部111bに沿って起立してキャップ150を取り付けるための筒状のキャップ装着部121cが一体に形成されている。   Specifically, the pump 120 includes a cylinder 121 that is attached to the mouth portion 111a and hangs down inside the mouth portion 111a. The cylinder 121 has a mounting cylinder part 121a that detachably holds the inside and outside of the mouth part 111a, and an annular groove formed between the mouth part 111a and the exterior part 111b on the outside of the mounting cylinder part 121a. A cylindrical cap mounting portion 121c is integrally formed with the outer portion standing along the exterior portion 111b to attach the cap 150.

他方、装着筒部121aの内側には、シリンダ下端部121bを介して口部111aの内側を起立するシリンダ本体121dが一体に形成されている。シリンダ本体121dの外側には、装着筒部121aとの相互間に形成された環状溝に配置され、ノズルヘッド130と共にシリンダ本体121dの上端を封止する筒状のシール部材122が設けられている。このシール部材122は、更にリターンスプリングSrを介してノズルヘッド130を弾支する。   On the other hand, on the inner side of the mounting cylinder part 121a, a cylinder body 121d is integrally formed so as to stand up on the inner side of the mouth part 111a via a cylinder lower end part 121b. A cylindrical seal member 122 that seals the upper end of the cylinder main body 121d together with the nozzle head 130 is provided on the outside of the cylinder main body 121d, which is disposed in an annular groove formed between the cylinder main body 121d and the mounting cylinder 121a. . The seal member 122 elastically supports the nozzle head 130 via a return spring Sr.

また、シリンダ下端部121bには、容器本体110とシリンダ本体121dとを通じさせる吸引口120aが形成されており、更に、吸引口120aの外側には、吸引筒121eが一体に設けられている。これにより、吸引筒121eは、吸引筒121eの全周に亘る、胴部113内側との相互間に、上側を肩部112で閉じられ下側が充填空間Rの一部として開放された下向きの環状凹空間cを形成する。   Further, a suction port 120a through which the container main body 110 and the cylinder main body 121d are passed is formed at the cylinder lower end 121b, and a suction cylinder 121e is integrally provided outside the suction port 120a. As a result, the suction cylinder 121e has a downwardly-circular annular shape with the upper side closed by the shoulder 112 and the lower side opened as a part of the filling space R between the inside of the body 113 and the entire circumference of the suction cylinder 121e. A concave space c is formed.

なお、吸引筒121eは、本形態の如く、シリンダ下端部121bに設ける必要は必ずしもなく、ポンプ120の下部としての構成であれば、シリンダ下端部121bを下側に延長することにより構成してもよい。   Note that the suction cylinder 121e is not necessarily provided at the cylinder lower end 121b as in this embodiment, and may be configured by extending the cylinder lower end 121b downward as long as it is configured as a lower part of the pump 120. Good.

また、吸引筒121eには、図1のX−X断面図に示すように、その軸線方向に沿って互いに向かい合う2つのスリットSが形成されている。このスリットSは、環状凹空間cを吸引口120aに通じさせるための通路として機能すればよいため、吸引筒121eには少なくとも1つ設ければよい。
Further, as shown in the XX sectional view of FIG. 1, the suction cylinder 121e is formed with two slits S facing each other along the axial direction thereof. Since the slit S only needs to function as a passage for allowing the annular concave space c to communicate with the suction port 120a, at least one slit S need only be provided in the suction cylinder 121e.

ノズルヘッド130は、その裏面から一体に垂下し、その内側に吐出口130bに通じる内部通路を形成する案内筒部131を有する。この案内筒部131は、シール部材122の内側にシリンダ本体121d内の気密状態を保ちつつ摺動可能に嵌合し、その内側には、ピストン123が摺動可能に保持されている。更に、案内筒部131は、その内側に、ピストン123の抜け止めの機能を有し、ピストン123と共に、後述する充填空間Rの内容物を加圧するポンププランジャ124が嵌合保持されている。   The nozzle head 130 has a guide tube portion 131 that hangs down integrally from the back surface thereof and forms an internal passage leading to the discharge port 130b inside. The guide cylinder 131 is slidably fitted inside the seal member 122 while maintaining the airtight state in the cylinder main body 121d, and the piston 123 is slidably held on the inside thereof. Further, the guide cylinder portion 131 has a function of preventing the piston 123 from being detached, and a pump plunger 124 that pressurizes the contents of a filling space R described later is fitted and held together with the piston 123.

符号140は、胴部113内側に摺動可能に配置され容器本体110の実質上の底部となる中皿である。中皿140は、図4に示すように、胴部113の内側に摺動可能に配置されるスライド部材141と、このスライド部材141の下側から脱落可能に嵌合する落下部材142とからなり、未使用状態では図1に示すように、底蓋部114よりも上側に位置し、容器本体110の内側に、この容器本体110との相互間に内容物の充填空間Rを形成する。   Reference numeral 140 denotes an intermediate dish that is slidably disposed inside the body 113 and serves as a substantial bottom of the container body 110. As shown in FIG. 4, the intermediate dish 140 includes a slide member 141 that is slidably arranged inside the body portion 113 and a drop member 142 that is detachably fitted from the lower side of the slide member 141. In the unused state, as shown in FIG. 1, a filling space R for contents is formed between the container body 110 and the container body 110 inside the container body 110, as shown in FIG.

詳細には、スライド部材141は、胴部113の内側に摺動可能に保持される外筒部141aと、この外筒部141aの内側に配置されその内側にシリンダ下端部121bの吸引筒121eを摺動自在に挿入可能な内筒部141bと、この内筒部141b及び外筒部141aを一体に繋いで、図2,3に示すように、容器本体110内の環状凹空間cに進入可能な環状の天壁部141cとを一体に有する。   Specifically, the slide member 141 includes an outer cylinder part 141a that is slidably held inside the body part 113, and a suction cylinder 121e of the cylinder lower end part 121b disposed inside the outer cylinder part 141a. The inner cylinder part 141b that can be slidably inserted, and the inner cylinder part 141b and the outer cylinder part 141a are integrally connected so that they can enter the annular concave space c in the container body 110 as shown in FIGS. And an annular top wall 141c.

落下部材142は、スライド部材141の下側からその内筒部141bの内側に摺動可能に嵌合する突起部142aを有する。この突起部142aはその上端eが閉じられた筒形状をなし、シリンダ下端部121bの吸引筒121eの下端が当接するための段部dが形成されている。これにより、突起部142aは、スライド部材141の内筒部141bに嵌合することで、天壁部141cと共に充填空間Rに発生した負圧に対しての受圧部を形成すると共に、当該負圧によって生じたスライド部材141との上昇に伴いその段部dが吸引筒121eの下端に接触して環状凹空間cを天壁部121cで閉じることで形成される、天壁部121cと環状凹空間cとからなる残量空間を形成する。   The dropping member 142 has a protruding portion 142a that is slidably fitted from the lower side of the sliding member 141 to the inner side of the inner cylindrical portion 141b. The protrusion 142a has a cylindrical shape with its upper end e closed, and is formed with a step portion d for contacting the lower end of the suction cylinder 121e of the cylinder lower end 121b. As a result, the protrusion 142a is fitted into the inner cylindrical portion 141b of the slide member 141, thereby forming a pressure receiving portion for the negative pressure generated in the filling space R together with the top wall portion 141c. The top wall 121c and the annular concave space are formed by the step d coming into contact with the lower end of the suction cylinder 121e and closing the annular concave space c with the ceiling wall 121c as the slide member 141 is raised by A remaining space consisting of c is formed.

また、落下部材142は、環状の底部142bを有し、この底部142bは突起部142aの下端に上げ底部fbを介して一体に繋がる。更に、落下部材142は、底部142bの外縁に一体に繋がり当該底部142bから起立する表示部142cを有する。表示部142cの外表面には、内容物が無くなったことを警告する表示I(例えば、図3においては「無くなったよ」)が設けられている。   Further, the dropping member 142 has an annular bottom portion 142b, and this bottom portion 142b is integrally connected to the lower end of the protruding portion 142a via the raised bottom portion fb. Further, the dropping member 142 has a display portion 142c that is integrally connected to the outer edge of the bottom portion 142b and stands up from the bottom portion 142b. On the outer surface of the display unit 142c, a display I (for example, “I'm gone” in FIG. 3) is provided to warn that the contents are gone.

なお、表示Iとは、文字、図形、記号、色彩、模様又はこれらの結合等の視覚的に訴えるものをいう。また、表示を設ける方法としては、前記突起に直接、印刷やラベリング等により表示を施す方法が挙げられるが、前記突起に印刷等で装飾を施した別部材を取り付けることも含む。   In addition, the display I means what appeals visually, such as a character, a figure, a symbol, a color, a pattern, or these combination. In addition, as a method of providing the display, a method of directly displaying the projection by printing, labeling, or the like can be given. However, it includes attaching another member decorated to the projection by printing or the like.

次に、本形態の作用を説明する。   Next, the operation of this embodiment will be described.

先ず使用者がノズルヘッド130を押下げると、充填空間R内の空気は吸引筒121eから吸引口120aを経てシリンダ本体121d内に入ってピストン123及びポンププランジャ124により加圧され、ノズルヘッド130の押下げによってその内圧が一定圧を超えると、ピストン123が案内筒部131の内側をスライドしてポンププランジャ124の側壁に形成した貫通孔124aを開放する。これにより、未使用時に充填空間R内にある空気が、貫通孔124aから案内筒部131内側の通路rを通ってノズルヘッドの吐出口130bから吐出される。   First, when the user depresses the nozzle head 130, the air in the filling space R enters the cylinder body 121d from the suction cylinder 121e through the suction port 120a and is pressurized by the piston 123 and the pump plunger 124. When the internal pressure exceeds a certain pressure by being pushed down, the piston 123 slides inside the guide tube 131 to open the through hole 124a formed in the side wall of the pump plunger 124. Thereby, the air in the filling space R when not in use is discharged from the discharge port 130b of the nozzle head through the passage r inside the guide tube 131 from the through hole 124a.

次に、使用者がノズルヘッド130から指を離すと、リターンスプリングSrの付勢力によって当該ノズルヘッド130が上昇し、ピストン123が案内筒部131の内側をスライドしてポンププランジャ124の貫通孔124aを閉じる。これにより、ノズルヘッド130が更に上昇すると、シリンダ121の内部及び充填空間Rに負圧が発生し、充填空間Rの内容物がシリンダ121の内部に導入される。   Next, when the user releases his / her finger from the nozzle head 130, the nozzle head 130 is lifted by the biasing force of the return spring Sr, and the piston 123 slides inside the guide tube portion 131 to pass through the through hole 124a of the pump plunger 124. Close. As a result, when the nozzle head 130 is further raised, a negative pressure is generated in the cylinder 121 and the filling space R, and the contents of the filling space R are introduced into the cylinder 121.

以後、ノズルヘッド130の押下げ及び復帰の繰り返せば、ポンプ120のポンプ動作により吐出口130bから内容物を噴出させることができ、これと同時に、中皿140は、スライド部材141の下端に落下部材142が嵌合した状態のまま、内容物の噴出に伴って充填空間R内に生じる負圧により内容物を押し上げつつ胴部113の内側を軸線Oに沿って上昇する。これにより、中皿140は、内容物の噴出に伴って生じる負圧を充填空間Rの容量を減少させることで解消する。   Thereafter, if pressing and returning of the nozzle head 130 are repeated, the contents can be ejected from the discharge port 130b by the pumping operation of the pump 120. At the same time, the inner plate 140 is dropped at the lower end of the slide member 141. While the 142 is fitted, the inside of the body 113 rises along the axis O while pushing up the contents by the negative pressure generated in the filling space R as the contents are ejected. As a result, the inner tray 140 eliminates the negative pressure that accompanies the ejection of the contents by reducing the capacity of the filling space R.

そして、内容物が無くなり、落下部材142の突起部142aに設けた段部dが充填空間R内の負圧によって生じたスライド部材141との上昇に伴い吸引筒121eに接触して落下部材142が胴部113内側を上昇できなくなると、図2に示すように、吸引筒121e(図2ではスリットsとして表示。)と、天壁部121cと環状凹空間cとからなる残量空間に発生する負圧より当該残量空間にスライド部材141のみを進入させる。   Then, the contents disappear, and the stepped portion d provided on the projecting portion 142a of the dropping member 142 comes into contact with the suction cylinder 121e as the slide member 141 is raised by the negative pressure in the filling space R, and the dropping member 142 If the inside of the body 113 cannot be raised, as shown in FIG. 2, the suction cylinder 121e (shown as a slit s in FIG. 2), a remaining space consisting of the top wall 121c and the annular concave space c is generated. Only the slide member 141 is caused to enter the remaining space from the negative pressure.

そして更にスライド部材141が進入すると、スライド部材141の内筒部141bとの嵌合により宙吊りになっていた落下部材142は、図2の二点鎖線に示すように、スライド部材141から抜け落ちて、図3に示すように、透明又は半透明の底蓋部114に接触する。これにより、落下部材142の表示部142cに設けた表示Iが底蓋部114を透して視認されるため、内容物が完全に無くなったことを視覚的に明らかにする。   When the slide member 141 further enters, the dropping member 142 that is suspended by fitting with the inner cylindrical portion 141b of the slide member 141 falls off the slide member 141 as shown by a two-dot chain line in FIG. As shown in FIG. 3, it contacts the transparent or translucent bottom lid 114. Thereby, since the display I provided on the display part 142c of the dropping member 142 is visually recognized through the bottom cover part 114, it is visually clarified that the contents are completely lost.

即ち、本形態によれば、容器本体110内に生じる負圧によって内容物を押し上げつつ上昇する中皿140を、胴部113内側を摺動可能なスライド部材141と、このスライド部材141の下端に落下可能に嵌合する落下部材142とで構成し、この落下部材142を、当該落下部材142と、ポンプ120の下部となる吸引筒121eとの接触により、胴部113下端に設けた透明又は半透明の底蓋部114に落下させて透視可能にしたから、内容物の残量を視覚的に確認することができる。   That is, according to the present embodiment, the inner plate 140 that rises while pushing up the contents by the negative pressure generated in the container main body 110 is attached to the slide member 141 that can slide inside the body 113 and the lower end of the slide member 141. The drop member 142 is fitted so as to be able to drop, and the drop member 142 is a transparent or semi-finished member provided at the lower end of the body 113 by contact between the drop member 142 and the suction cylinder 121e which is the lower part of the pump 120. Since the liquid is dropped on the transparent bottom lid 114 and can be seen through, the remaining amount of the contents can be visually confirmed.

従って、本形態によれば、容器本体110全体を不透明とした場合にも、内容物の残量を視覚的に確認することができる。しかも、本形態によれば、容器本体110の内容物は、図3に示すように、スライド部材141の天壁部141bが肩部112の下面に接触する位置(スライド部材141の上死点)まで残さず吐出させることができる。   Therefore, according to the present embodiment, the remaining amount of contents can be visually confirmed even when the entire container body 110 is opaque. Moreover, according to the present embodiment, the contents of the container main body 110 are, as shown in FIG. 3, the position where the top wall portion 141b of the slide member 141 contacts the lower surface of the shoulder portion 112 (the top dead center of the slide member 141). It is possible to discharge without leaving.

なお、落下部材142は、突起部142aのみとし、又は、突起部142a の下端に様々なものを繋げることができるが、本形態のように、突起部142aに繋がる底部142bと、この底部142bの外縁から起立する表示部142cとを有することが好ましい。この場合、表示部142cの外表面に、表示Iを設けることにより、使用者への警告を更に確実なものにできる。   The dropping member 142 can be the protrusion 142a only, or various things can be connected to the lower end of the protrusion 142a.As in this embodiment, the bottom 142b connected to the protrusion 142a and the bottom 142b It is preferable that the display unit 142c rises from the outer edge. In this case, by providing the display I on the outer surface of the display unit 142c, a warning to the user can be further ensured.

また、表示部142cは、図1に示すように、スライド部材141の外筒部141aの内側に摺動可能に嵌合する筒形状としてなるが、この場合、落下部材142はスライド部材141に対して比較的強固に嵌合するため、内容物が残存している状態での誤った落下部材142の落下を回避することができる。   Further, as shown in FIG. 1, the display portion 142c has a cylindrical shape that is slidably fitted inside the outer tube portion 141a of the slide member 141. Therefore, it is possible to avoid the dropping member 142 from being erroneously dropped while the contents remain.

更に、本形態は、図3に示すように、スライド部材141の内筒部141bの内側と、落下部材142の突起部142aの外側とにそれぞれ、互いに着脱可能に係合する凹凸形状からなる係合部U1,U2を設けている。この場合、内容物が残存している状態での誤った落下部材142の落下を更に確実に回避することができる。   Further, as shown in FIG. 3, this embodiment has a concave and convex shape that is detachably engaged with the inner side of the inner cylinder part 141 b of the slide member 141 and the outer side of the protrusion part 142 a of the dropping member 142. Joint portions U1 and U2 are provided. In this case, it is possible to more reliably avoid erroneous dropping of the dropping member 142 in the state where the contents remain.

図5は、本発明の第二の形態であるポンプ付き容器200の未使用状態を一部断面で示す側面図であり、図6は、同形態の内容物吐出完了直前の状態を一部断面で示す側面図である。また、図7は、同形態において、内容物が残り少なくなったことを落下部材で表示している状態を一部断面で示す側面図である。更に、図8(a)〜(c)はそれぞれ、後述の中皿240、それを構成するスライド部材241及び落下部材242を示す斜視図である。なお、以下の説明において、図1等に示す第一の形態と同一の構成は、同一符号をもって、その説明を省略する。   FIG. 5 is a side view showing the unused state of the pump-equipped container 200 according to the second embodiment of the present invention in a partial cross section, and FIG. 6 is a partial cross section showing the state immediately before completion of the content discharge in the same form. It is a side view shown by. Moreover, FIG. 7 is a side view which shows the state which is displaying with the dropping member that the content remained few in the same form in a partial cross section. Further, FIGS. 8A to 8C are perspective views showing a middle plate 240 described later, a slide member 241 and a drop member 242 constituting the same, respectively. In the following description, the same components as those in the first embodiment shown in FIG.

本形態も、中皿240は、胴部113の内側に摺動可能に配置されるスライド部材241と、このスライド部材241の下側から脱落可能に嵌合する落下部材242とからなり、未使用状態では図5に示すように、底蓋部114よりも上側に位置し、容器本体110の内側に、この容器本体110との相互間に内容物の充填空間Rを形成する。   Also in this embodiment, the inner plate 240 is composed of a slide member 241 that is slidably arranged inside the body portion 113 and a drop member 242 that is detachably fitted from the lower side of the slide member 241 and is not used. In this state, as shown in FIG. 5, a filling space R for contents is formed between the container body 110 and the container body 110 inside the container body 110.

詳細には、スライド部材241は、胴部113の内側に摺動可能に保持される外筒部241aと、この外筒部241aを一体に繋いで容器本体110に発生した負圧に対する受圧部を形成する天壁部241bとを一体に有する。これにより、スライド部材241は、充填空間Rに発生した負圧に対しての受圧部を形成する。   Specifically, the slide member 241 includes an outer cylinder part 241a that is slidably held inside the body part 113, and a pressure receiving part for negative pressure generated in the container body 110 by integrally connecting the outer cylinder part 241a. A ceiling wall portion 241b to be formed is integrally provided. As a result, the slide member 241 forms a pressure receiving portion for the negative pressure generated in the filling space R.

天壁部241bは、その中心付近に吸引筒121eを挿入可能な封止突起部分Pを有し、また、封止突起部分Pの外側に、吸引筒121eの下端との接触によって変形する環状の薄肉部分tを有する。また、スライド部材241は、天壁部241bの裏面に、薄肉部分tよりも外側から垂下して当該薄肉部分tを起点に拡張可能な内筒部241cを一体に有し、更に、天壁部241bは、内筒部241cと外筒部241aとの相互間に、後述の図7に示すように、内筒部241cの拡張によって肩部112と接触可能なストッパ部分Stを有する。   The top wall portion 241b has a sealing projection portion P into which the suction cylinder 121e can be inserted in the vicinity of the center thereof, and an annular shape deformed by contact with the lower end of the suction cylinder 121e outside the sealing projection portion P. It has a thin portion t. Further, the slide member 241 integrally has an inner cylindrical portion 241c that extends from the outer side of the thin portion t and can be expanded from the thin portion t on the back surface of the top wall portion 241b. As shown in FIG. 7 described later, the 241b has a stopper portion St that can come into contact with the shoulder portion 112 by extending the inner cylinder portion 241c, between the inner cylinder portion 241c and the outer cylinder portion 241a.

落下部材242は、スライド部材241の下側からその内筒部241cの内側に摺動可能に嵌合する突起部242aを有する。この突起部242aの上端部分eは、充填空間R内の負圧によって生じたスライド部材241との上昇に伴い吸引筒121eと共に薄肉部分tを挟持する筒形状をなす。これにより、充填空間Rに発生した負圧によって生じたスライド部材141との上昇に伴いその上端部分eが吸引筒121eと共に薄肉部分tを挟持すれば、天壁部121cと環状凹空間cとからなる残量空間での負圧の発生に伴い当該薄肉部分tを起点とした内筒部241cの外側への拡張が実現される。   The dropping member 242 has a protrusion 242a that is slidably fitted from the lower side of the slide member 241 to the inside of the inner cylindrical portion 241c. The upper end portion e of the protruding portion 242a has a cylindrical shape that sandwiches the thin portion t together with the suction tube 121e as the slide member 241 is raised by the negative pressure in the filling space R. Thereby, if the upper end portion e sandwiches the thin portion t together with the suction cylinder 121e as the slide member 141 is raised by the negative pressure generated in the filling space R, the top wall portion 121c and the annular concave space c are separated from each other. As the negative pressure is generated in the remaining space, the expansion of the inner cylindrical portion 241c from the thin-walled portion t to the outside is realized.

また、落下部材242も、環状の底部242bを有し、この底部242bは突起部242aの下端に上げ底部fbを介して一体に繋がる。更に、落下部材242は、底部242bの外縁に一体に繋がり当該底部242bから起立する表示部242cを有する。表示部242cの外表面には、内容物が残り少なくなったことを警告する表示Iが設けられている。   The dropping member 242 also has an annular bottom portion 242b, and this bottom portion 242b is integrally connected to the lower end of the protruding portion 242a via the raised bottom portion fb. Further, the dropping member 242 has a display portion 242c that is integrally connected to the outer edge of the bottom portion 242b and stands up from the bottom portion 242b. A display I is provided on the outer surface of the display unit 242c to warn that the content is low.

次に、本形態の作用を説明する。   Next, the operation of this embodiment will be described.

ノズルヘッド130の押下げ及び復帰の繰り返しにより内容物を吐出させるに当たっての操作は第一の同様である。   The operation for discharging the contents by repeatedly pressing and returning the nozzle head 130 is the same as the first.

そして、内容物が無くなり、スライド部材241の天壁部241bが充填空間R内の負圧によって生じたスライド部材141との上昇に伴いシリンダ122の吸引筒121eに当接して胴部113内側を上昇できなくなると、図6に示すように、吸引筒121e(図6ではスリットsとして表示。)と、天壁部121cと環状凹空間cとからなる残量空間での負圧の発生に伴い、天壁部241bの薄肉部分tが持ち上げられるように変形して当該薄肉部分tを起点とした内筒部241cの外側に向かう末広がり状の拡張が実現される。   Then, the contents disappear, and the top wall 241b of the slide member 241 is brought into contact with the suction cylinder 121e of the cylinder 122 as it rises with the slide member 141 caused by the negative pressure in the filling space R, and rises inside the barrel 113. When it becomes impossible, as shown in FIG. 6, with the generation of negative pressure in the remaining space consisting of the suction cylinder 121e (shown as slit s in FIG. 6), the top wall 121c and the annular concave space c, The thin wall portion t of the top wall portion 241b is deformed so as to be lifted, and the divergent expansion toward the outside of the inner cylinder portion 241c starting from the thin wall portion t is realized.

そして更に薄肉部分tを起点とした拡張が進むと、スライド部材241の内筒部241cとの嵌合により宙吊りになっていた落下部材242は、図2の二点鎖線に示すように、スライド部材241から抜け落ちて、図6,7の実線に示すように、透明又は半透明の底蓋部114に接触する。これにより、落下部材242の表示部242cに設けた表示Iが底蓋部114を透して視認されるため、内容物が残り少なくなったことを視覚的に明らかにする。   Further, when the expansion starts from the thin-walled portion t, the dropping member 242 suspended by the fitting with the inner cylindrical portion 241c of the sliding member 241 is moved into the sliding member as shown by a two-dot chain line in FIG. As shown by the solid lines in FIGS. 6 and 7, it comes off from 241 and contacts the transparent or translucent bottom cover 114. Thereby, since the display I provided on the display unit 242c of the dropping member 242 is visually recognized through the bottom cover unit 114, it is visually clarified that the content is reduced.

即ち、本形態によれば、容器本体110内に生じる負圧によって内容物を押し上げつつ上昇する中皿240を、胴部113内側を摺動可能なスライド部材241と、このスライド部材241の下側に落下可能に嵌合する落下部材242とで構成し、この落下部材242を、スライド部材241と、ポンプ120の下部である吸引筒121eとの接触により、胴部110下端に設けた透明又は半透明の底蓋部114に落下させて透視可能にしたから、内容物の残量を視覚的に確認することができる。   That is, according to the present embodiment, the intermediate plate 240 that rises while pushing up the contents by the negative pressure generated in the container body 110, the slide member 241 that can slide inside the body 113, and the lower side of the slide member 241 The drop member 242 is fitted with a drop member 242 so that the drop member 242 can be dropped. Since the liquid is dropped on the transparent bottom lid 114 and can be seen through, the remaining amount of the contents can be visually confirmed.

従って、本形態によっても、容器本体110全体を不透明とした場合にも、内容物の残量を視覚的に確認することができる。しかも、本形態においても、容器本体110の内容物は、図7に示すように、スライド部材241の天壁部241bに設けたストッパStが肩部112の下面に接触する位置(スライド部材241の上死点)まで残さず吐出させることができる。   Therefore, also in this embodiment, the remaining amount of contents can be visually confirmed even when the entire container body 110 is opaque. In addition, also in this embodiment, as shown in FIG. 7, the content of the container main body 110 is a position where the stopper St provided on the top wall portion 241b of the slide member 241 contacts the lower surface of the shoulder portion 112 (the slide member 241 It can be discharged without leaving the top dead center.

なお、落下部材242も、突起部242aのみとし、又は、突起部242a の下端に様々なものを繋げることができるが、本形態のように、突起部242aに繋がる底部242bと、この底部242bの外縁から起立する表示部242cとを有すれば、表示部242cの外表面に、表示Iを設けることにより、使用者への警告を更に確実なものにできる。   The dropping member 242 can be only the protruding portion 242a, or various members can be connected to the lower end of the protruding portion 242a, but as in this embodiment, the bottom portion 242b connected to the protruding portion 242a and the bottom portion 242b If the display unit 242c stands up from the outer edge, the display I is provided on the outer surface of the display unit 242c, so that the warning to the user can be further ensured.

また、表示部142c,242cも、スライド部材241の外筒部241aの内側に摺動可能に嵌合する筒形状としてなるものとすれば、第一の形態と同様、内容物が残存している状態での誤った落下部材242の落下を回避することができる。   Further, if the display portions 142c and 242c also have a cylindrical shape that is slidably fitted inside the outer cylinder portion 241a of the slide member 241, the contents remain as in the first embodiment. In this state, it is possible to avoid the fall of the dropping member 242 by mistake.

更に、本形態は、スライド部材241の内筒部241cの内側と、落下部材242の突起部242aの外側とにそれぞれ、互いに着脱可能に係合する凹凸形状からなる係合部U1,U2を設ければ、第一の形態と同様、内容物が残存している状態での誤った落下部材142,242の落下を更に確実に回避することができる。   Further, in this embodiment, engaging portions U1 and U2 having concave and convex shapes that are detachably engaged with each other are provided on the inner side of the inner cylindrical portion 241c of the slide member 241 and the outer side of the protruding portion 242a of the dropping member 242, respectively. As in the first embodiment, it is possible to more reliably avoid erroneous dropping of the dropping members 142 and 242 in the state where the contents remain.

上述したところは、本発明の一形態を説明するものであるが、特許請求の範囲において、種々の変更を加えることができる。例えば、容器本体110は、遮光性の色彩を有する合成樹脂に限らず、遮光性の色彩を有するシュリンクラベルで覆われている場合には、その材質は問わない。また、本発明に係るポンプも、上述した形態のポンプに限らず、既存のものを使用してもよい。また、上述した形態の各構成はそれぞれ、目的及び用途に応じて適宜組み合わせることができる。   While the above is to describe one embodiment of the present invention, various modifications can be made within the scope of the claims. For example, the material of the container body 110 is not limited to a synthetic resin having a light-shielding color, and any material may be used when it is covered with a shrink label having a light-shielding color.
