Description

本発明は詰替用液体袋を用いた液体取出装置及び液体取出方法に関し、詳しくは可撓性の液体袋に充填された液体を吸引・注出するエアレスタイプの液体の取出装置及び取出方法に関する。 The present invention relates to a liquid take-out apparatus and a liquid take-out method using a refilling liquid bag, and more particularly to an airless type liquid take-out apparatus and a take-out method for sucking and dispensing liquid filled in a flexible liquid bag. .

可撓性を有する液体袋に充填された液体をポンプ手段により吸引・注出するに従って前記液体袋内の負圧化に伴って収縮（縮小）していく構成のエアレスタイプの液体取出装置では、使用開始の時点（図９（Ａ）参照）では液体の吸引・注出を問題なく行うことができるが、液体残量が少なくなってくると吸引管の吸引口に液体袋の内壁部が徐々に吸い寄せられ（図９の（Ｂ）参照）、吸引口と液体とを連絡する通液路が絶たれてしまい（図９の（Ｃ）参照）、液体袋内の液体の全量の吸引・注出ができなくなることが多々ある。 In the airless type liquid take-out device configured to contract (shrink) with the negative pressure in the liquid bag as the liquid filled in the liquid bag having flexibility is sucked and dispensed by the pump means, At the time of start of use (see FIG. 9A), the liquid can be sucked and dispensed without any problem. However, when the remaining amount of liquid decreases, the inner wall of the liquid bag is gradually formed in the suction port of the suction pipe. (See FIG. 9B), the liquid passage connecting the suction port and the liquid is cut off (see FIG. 9C), and the entire amount of liquid in the liquid bag is sucked and poured. There are many cases where it is impossible to get out.

かかる問題を解決するため、吸引管の長さを液体袋の底部付近まで伸ばす構成とすることにより液体袋の底部における液体の残留を防ぐことが行われているが、この場合、液体袋の底部の液体の吸引・注出は問題なく行えるようになるが、吸引管の根元部である液体袋の上部に液体が残留してしまうという問題が生じ易い。 In order to solve such a problem, it has been attempted to prevent the liquid from remaining at the bottom of the liquid bag by extending the length of the suction tube to the vicinity of the bottom of the liquid bag. Although the liquid can be sucked and dispensed without any problem, there is a problem that the liquid remains on the upper part of the liquid bag that is the root of the suction pipe.

そこで本発明者は、吸引管の上端近傍の側壁部分と下端近傍の側壁部分の各々に吸引孔を設ける構成によって、先ず上方の吸引孔から液体袋上部における吸引・注出を始め、この上方での吸引・注出により液体袋の上部が収縮して上方の吸引孔を閉塞した後は、下方の吸引孔から液体袋下部における吸引・注出を始めることにより、液体袋内の液体の吸引・注出が限界に達した際の液体残留を限りなく少なく抑制する技術を先に提案している（特許文献１参照）。 In view of this, the present inventor started suction / pourage on the upper part of the liquid bag from the upper suction hole by providing a suction hole in each of the side wall part near the upper end and the side wall part near the lower end of the suction pipe. After the upper part of the liquid bag contracts due to the suction / pumping of the liquid and the upper suction hole is closed, the suction / pumping of the liquid in the liquid bag is started by starting suction / pumping at the lower part of the liquid bag from the lower suction hole. The technique which suppresses the liquid residue at the time of pouring to the limit as much as possible is proposed previously (refer patent document 1).

本発明者は、当該技術について更に研究を続けたところ、より簡素な構成による液体の吸引・注出においても液体袋内の液体の吸引・注出が限界に達した際の液体残留を限りなく少ない量に抑制することができることを見出した。 As a result of further research on the technology, the present inventor has found that the liquid remaining in the liquid bag when the suction / pumping of the liquid in the liquid bag reaches the limit even in the suction / pumping of the liquid with a simpler configuration is not limited. It has been found that it can be suppressed to a small amount.

そこで本発明の目的は、より簡素な構成により、吸引・注出力が高く、しかも充填液体の略全量を使い切ることができる詰替用液体袋を用いた液体取出装置及び液体取出方法を提供することにある。 Accordingly, an object of the present invention is to provide a liquid take-out apparatus and a liquid take-out method using a refilling liquid bag that has a simpler configuration, has a high suction / pour-out power, and can use up almost the entire amount of the filled liquid.

請求項１又は６に示す発明によれば、より簡素な構成により、吸引・注出力が高く、しかも充填液体の略全量を使い切ることができる詰替用液体袋を用いた液体取出装置又は液体取出方法を提供することができる。 According to the first or sixth aspect of the present invention, the liquid take-out apparatus or the liquid take-out using the refilling liquid bag that has a simpler configuration and has a high suction / pour-out power and can use up almost the entire amount of the filled liquid. A method can be provided.

特に、液体が未充填の時に扁平である両側ヒートシール構成の詰替用液体袋の場合、液体の残量が少なくなるにしたがって液体袋が未充填時の形状である扁平状に戻ろうとする特性を有することによって液体残量の減少に応じて段々と内壁部同士がくっ付いていき通液路が閉塞されてしまうが、本構成によれば、液体残量の減少に応じて詰替用液体袋が扁平状に戻るのが抑制され水平方向断面形状（略正三角形・略正方形を含む略正多角形乃至は略円形のいずれかの形状）を維持しようとしたまま略全周方向から潰れるように細くなっていき、この潰れていく過程において通水路が幾筋も発生する状態となり易いので、通液路が閉塞されることなく充填されている液体の略全量の吸引・抽出が可能となる。 In particular, in the case of a refillable liquid bag with a double-sided heat seal configuration that is flat when the liquid is not filled, the characteristic is that the liquid bag tends to return to the flat shape that is in the unfilled form as the remaining amount of liquid decreases. As the liquid remaining amount decreases, the inner walls gradually adhere to each other and the liquid passage is blocked, but according to this configuration, the refilling liquid corresponds to the liquid remaining amount decreasing. The bag is prevented from returning to a flat shape, and the bag is crushed from substantially the entire circumference while maintaining the horizontal cross-sectional shape (a shape of either a substantially regular polygon or a substantially circular shape including a substantially regular triangle or a substantially square shape). In the process of being crushed, the water passage tends to be in a state where a number of streaks are generated, so that almost all of the filled liquid can be sucked and extracted without being blocked. .

また、吸引管が詰替用液体袋の中央より上方に配設される長さであるため、吸引・抽出に際しては、該吸引管の根元部である詰替用液体袋の上部に液体が残留することがなく、吸引・抽出が可能となる。
更に、液体取出装置の製造に際しては、吸引管の金型の小型化及び使用原材料の少量化等により吸引管の製造コストを下げることができる。
In addition, since the suction pipe is long enough to be disposed above the center of the refill liquid bag, the liquid remains on the top of the refill liquid bag, which is the base of the suction pipe, during suction and extraction. This makes it possible to perform suction and extraction.
Furthermore, when manufacturing the liquid take-out device, the manufacturing cost of the suction tube can be reduced by downsizing the mold of the suction tube and reducing the amount of raw materials used.

尚、詰替用液体袋の底部付近まで吸引管を伸ばす構成のものでは、詰替用液体袋の長さに応じた長さの吸引管を製造用意しなければならないが、本発明に用いる吸引管によれば、詰替用液体袋の略中央部より上方に配設される長さであればよいので、様々な長さの液体袋に対応することができる。
尚また、吸引管が詰替用液体袋の略中央部より下方にまで進出する長さとなって本発明の範囲外とはなるが、より長さの短い小容量タイプの詰替用液体袋に用いる吸引管としても利用することができるので、様々な容量の液体取出装置を製造する場合の総合的な製造コストを下げることが可能となる。
尚また更に、詰替用液体袋の対向する両側の２辺の封止部以外については押圧しなくてもよいので、液体取出装置のデザインを特別な制限無く自由に且つ多様に構成することができる。 In the case of a structure in which the suction tube is extended to the vicinity of the bottom of the refill liquid bag, a suction tube having a length corresponding to the length of the refill liquid bag must be manufactured and prepared. According to the pipe, any length may be used as long as it is disposed above the substantially central portion of the refilling liquid bag, so that it can correspond to liquid bags of various lengths.
In addition, the length of the suction tube that extends from the substantially central portion of the refill liquid bag to the lower side is outside the scope of the present invention. Since it can also be used as a suction tube to be used, it is possible to reduce the overall manufacturing cost when manufacturing liquid take-out devices of various capacities.
Still further, since it is not necessary to press the portions other than the sealing portions on the opposite sides of the refilling liquid bag, the design of the liquid take-out apparatus can be freely and variously configured without any particular limitation. it can.

請求項２又は７に示す発明によれば、押圧する必要のない詰替用液体袋の上部３分の２については、該詰替用液体袋や液体取出装置のデザインを特別な制限無く自由に且つ多様に構成することができる。 According to the second or seventh aspect of the invention, the upper two-thirds of the refilling liquid bag that does not need to be pressed can be freely designed without any particular restrictions on the design of the refilling liquid bag and the liquid take-out device. In addition, various configurations can be made.

請求項３に示す発明によれば、詰替用液体袋の未充填時の形状がより扁平状である、上部の１辺についてもヒートシールによる封止部を有する場合であっても、通液路が閉塞されることなく充填されている液体の略全量の吸引・抽出が可能となる。 According to the invention shown in claim 3, even when the refilling liquid bag has a flatter shape when it is not filled, and the upper side also has a sealing portion by heat sealing, the liquid passage It is possible to suck and extract substantially the entire amount of liquid filled without blocking the passage.

請求項４に示す発明によれば、詰替用液体袋内の液体が減少するに従って下部に残留し易くなるマチ付き底部を有する場合であっても、通液路が閉塞されることなく充填されている液体の略全量の吸引・抽出が可能となる。 According to the fourth aspect of the present invention, the liquid passage is filled without being clogged even when it has a gusseted bottom portion that tends to remain in the lower portion as the liquid in the refill liquid bag decreases. It is possible to aspirate and extract almost the entire amount of liquid.

請求項５に示す発明によれば、詰替用液体袋を、載置台に載置又はケース体に収納することにより２辺の封止部に対する押圧を維持することができるので、液体の略全量の吸引・注出が完了するまで通液路が閉鎖されることがない。 According to the fifth aspect of the present invention, since the refilling liquid bag can be maintained on the mounting table or stored in the case body, the pressure against the sealing portions on the two sides can be maintained, so that the substantially total amount of liquid can be maintained. The liquid passage is not closed until the suction and dispensing of the liquid is completed.

前記吸引管４は、その先端部４１及び全体が前記詰替用液体袋２の略中央部より上方に配設されており、
前記詰替用液体袋２は、少なくとも対向する両側の２辺にヒートシールによる封止部２１・２２が設けられた合成樹脂製の袋体であり、
且つ液体５の吸引・注出に際して、該詰替用液体袋２の水平方向断面形状が略正三角形・略正方形を含む略正多角形乃至略円形のいずれかの形状（本実施例では、図４に示す略円形）に近似するように、該詰替用液体袋２の対向する２辺の封止部２１・２２に対して外側方向から押圧し、この押圧を維持した状態で前記ポンプ体３の動作を行う構成である。 First, as shown in FIG. 1, a liquid take-out device 1 according to the present invention includes a refill liquid bag 2 containing a liquid, and a liquid suction / pumping means mounted on the top of the refill liquid bag 2. A pump body 3, and a suction pipe 4 that is attached to the suction portion of the pump body 3 in a communicating state and is inserted and disposed inside the refill liquid bag 2.
As the liquid 5 in the refill liquid bag 2 is aspirated and dispensed by the operation of the pump body 3, as shown in FIGS. 1A to 1D, the negative in the refill liquid bag 2 is reduced. It has an airless type structure that shrinks (shrinks) with pressure,
The suction tube 4 has a distal end portion 41 and the whole disposed above a substantially central portion of the refill liquid bag 2,
The refill liquid bag 2 is a synthetic resin bag body provided with sealing parts 21 and 22 by heat sealing on at least two sides on opposite sides,
In addition, when the liquid 5 is sucked and dispensed, the horizontal cross-sectional shape of the refill liquid bag 2 is any one of a substantially regular polygon and a substantially circular shape including a substantially regular triangle and a substantially square (in the present embodiment, FIG. The pump body is pressed against the sealing portions 21 and 22 on the two opposite sides of the refill liquid bag 2 so as to approximate to the substantially circular shape shown in FIG. 3 is performed.

２辺の封止部２１・２２に対する外側方向からの押圧は、図３（Ａ）に符号Ｙ（Ｙ１〜Ｙ４）として示す。
この２辺の封止部２１・２２に対する押圧の領域としては、詰替用液体袋２の少なくとも下部３分の１の位置（図３（Ａ）の仮想線Ｘ２の位置）までに対して行われる押圧（同図の矢符Ｙ４及びＹ３）であれば好ましく、詰替用液体袋２の略中央部の位置（同図の仮想線Ｘ１の位置）までに対して行われる押圧（同図の矢符Ｙ４・Ｙ３・Ｙ２）であればより好ましい。
尚、この押圧は、吸引管４の先端部４１の位置での押圧である矢符Ｙ１での押圧を上限とし、これより上方での押圧は行っても行わなくてもよい。 The pressing from the outside direction with respect to the sealing parts 21 and 22 on the two sides is shown as a symbol Y (Y1 to Y4) in FIG.

Any horizontal cross-sectional shape (a substantially regular polygon including a substantially regular triangle or a substantially square or a substantially circular shape) that is prevented from returning to a flat shape (see FIG. 2B), which is a shape when it is not filled. As shown in FIGS. 1 (C) and 1 (D), as shown in FIGS. 1 (C) and 1 (D), a state where a number of water passages are generated in the process of being crushed. (See (D) of FIG. 1). Therefore, it is possible to suck and extract substantially the entire amount of the filled liquid 5 without blocking the liquid passage.

また、吸引管４が詰替用液体袋２の中央より上方に配設される長さであるため、吸引・抽出に際しては、図１（Ｂ）〜（Ｄ）に示すように該吸引管４の根元部である詰替用液体袋２の上部に液体５が残留することがなく、吸引・抽出が可能となる。 Further, since the suction tube 4 is long enough to be disposed above the center of the refill liquid bag 2, the suction tube 4 is used for suction and extraction as shown in FIGS. 1 (B) to (D). The liquid 5 does not remain in the upper part of the refill liquid bag 2 that is the root of the liquid, and suction and extraction are possible.
