Description

本発明は、たとえばパーマ用薬品、液体石鹸、シャンプー、インキ、塗料等の化学品、医薬品、飲料水等の液状体又はトナー、食品、洗剤等の粉体が充填される容器に用いられる連結システムに関する。   The present invention relates to a connecting system used for containers filled with powders such as chemicals such as permanent chemicals, liquid soaps, shampoos, inks and paints, liquids such as pharmaceuticals and drinking water, or powders such as toners, foods and detergents. About.

従来、液状体や粉体が充填される容器に用いられる再封止可能な連結システムとしては、例えば、図２４に示すような連結システムがある（例えば、特許文献１参照。）。即ち、連結システムとして雌部材２０１とプラグ２０２と雄部材２０３とを備えているものが提案されている。雌部材２０１は上下方向に貫通した横断面円形導通路２１１を有しかつ容器の開口内に固定される。プラグ２０２は雌部材２０１に連結され、かつ雌部材２０１の上端部に着脱自在に係合して導通路２１１の上端開口を閉鎖しうる。雄部材２０３はプラグ２０２に係合する頭部２３１および頭部２３１の下方に連なる横断面環状の棒状部２３２を有しかつ雌部材２０１の導通路内に下方から抜き差し自在に差し込まれる。雄部材２０３の棒状部２３２には、その下端から上端部に至る流体通路２３３の周囲の部分に、雄部材２０３が上端位置に達した際に雌部材２０１の上端よりも上方に位置しかつ流体通路２３３を外部に通じさせる貫通孔２３４が形成されている。雄部材２０３を雌部材２０１の導通路２１１内に挿入して上昇させることにより、その頭部２３１がプラグ２０２に係合するとともにプラグ２０２が雌部材２０１の上端部から外れ、かつ貫通孔２３４の少なくとも一部が雌部材２０１上端よりも上方に位置し、容器２００が開栓され、内容物の注出入ができる。雄部材２０３を下降させることにより、頭部２３１と係合しているプラグ２０２が下降させられるとともに雌部材２０１の上端部に係合させられ流体通路２３３の上端開口が閉鎖され、かつ雄部材２０３の頭部２３１がプラグから外れるようになされている。   Conventionally, as a re-sealable connection system used for a container filled with a liquid or powder, for example, there is a connection system as shown in FIG. 24 (see, for example, Patent Document 1). That is, a connection system including a female member 201, a plug 202, and a male member 203 has been proposed. The female member 201 has a circular cross-sectional passage 211 that penetrates in the vertical direction and is fixed in the opening of the container. The plug 202 is connected to the female member 201 and can detachably engage with the upper end portion of the female member 201 to close the upper end opening of the conduction path 211. The male member 203 has a head portion 231 that engages with the plug 202 and a bar-shaped portion 232 having an annular cross section that continues to the lower portion of the head portion 231, and is inserted into the conduction path of the female member 201 so as to be freely inserted and removed from below. The rod-like portion 232 of the male member 203 is positioned above the upper end of the female member 201 when the male member 203 reaches the upper end position in a portion around the fluid passage 233 extending from the lower end to the upper end portion, A through-hole 234 that allows the passage 233 to communicate with the outside is formed. By inserting the male member 203 into the conduction path 211 of the female member 201 and raising the male member 203, the head 231 engages with the plug 202, the plug 202 comes off the upper end of the female member 201, and the through hole 234 At least a part is located above the upper end of the female member 201, the container 200 is opened, and the contents can be poured out. By lowering the male member 203, the plug 202 engaged with the head portion 231 is lowered and engaged with the upper end portion of the female member 201, the upper end opening of the fluid passage 233 is closed, and the male member 203 is closed. The head portion 231 is detached from the plug.

この連結システムでは、プラグ２０２と雄部材２０３の係合は、プラグ２０２内周面と雄部材２０３の頭部２３１にて行う構造をとっており、そのため、係合部であるプラグ２０２内周面と雄部材２０３の頭部２３１の寸法精度が要求される。しかしながら、プラグ２０２内周面は射出成形法により製造される際、中子が導通路２１１下側に抜かれるため、金型がアンダーカットとなり、中子を無理抜きする必要がある。係合力にばらつきが生じさせないように高い寸法精度を得るには、金型と成形技術に高い精度が求められ、コストアップとなる問題がある。   In this connection system, the plug 202 and the male member 203 are engaged with each other at the inner peripheral surface of the plug 202 and the head portion 231 of the male member 203. Therefore, the inner peripheral surface of the plug 202 which is an engaging portion. Therefore, the dimensional accuracy of the head 231 of the male member 203 is required. However, when the inner peripheral surface of the plug 202 is manufactured by an injection molding method, since the core is pulled out below the conduction path 211, the mold is undercut and the core needs to be forcibly removed. In order to obtain high dimensional accuracy so as not to cause variations in the engagement force, high accuracy is required for the mold and the molding technique, which increases the cost.

The main fitting portion 22 is formed with an annular protrusion 23 that is hooked to the annular inner protrusion 12 of the opening inner surface 13 of the female member 1 over the entire circumference, and the annular concave groove toward the skirt portion 21. 24, and a bulging portion 25 for sealing a gap with the inner surface 13 of the opening is formed so as to fit in a liquid-tight manner. Further, a stop surface 26 that is in liquid-tight contact with the end surface of the opening 11 of the female member 1 is formed. On the other side of the main fitting portion 22 of the plug 2, an inclined portion 27 whose temporary outer diameter is reduced toward the tip is formed to guide the inner surface 13 of the opening of the female member to the annular groove 24. . An annular inward protrusion 31 having at least one notch 30 is formed in the vicinity of the inlet of the inner surface 29 of the plug 2. In addition, a recess 32 is formed in the bottom so as to come into contact with the top surface 46 of the head of the male member 3 when the male member 3 is pushed in.

雄部材３はその先端部４１の先に頭部４２を備えている。頭部４２には当接面４３、係合面４４を有した突起４５が縦方向に少なくとも一つ以上付設されている。突起４５の形状は、雄部材３の頭部４２をプラグ２の受容部２８に押込む際、突起４５がプラグ２の環状内方突出部３１に付設された切欠き３０を通り抜けることができるような形状であれば、特に限定はされない。同様の理由より突起４５を複数個付設する場合は、突起４５の位置は雌部材１の切欠き３０の位置に対応した位置に付設する必要があり、金型の構造上からは、縦軸から１８０度の間隔で２個づつ配置するのが比較的簡単で好ましい。しかしながら、突起４５と環状内方突出部３１の切欠き３０の数は特に限定されるものではない。先端部４１には先端から順に、頭部４２、環状凹溝４７、貫通孔４８を有する。先端部４１の隣りには、その内部に頭部付近から他方端に至る流体通路５０が設けられた棒状部４９が形成されている。流体通路５０は頭部側開口の貫通孔４８を介して外部と繋がっている。棒状部４９と先端部４１の間にはOリング５１を取り付けることができるように環状溝部５２が設けられている。このOリング５１は必ずしも必要ではないが、このOリング５１により雌部材１の流体通路５０と雄部材３の棒状部４９の外周面との間が完全にシールされる。   The male member 3 includes a head portion 42 at the tip of the tip portion 41. At least one protrusion 45 having a contact surface 43 and an engagement surface 44 is attached to the head 42 in the vertical direction. The shape of the protrusion 45 is such that when the head portion 42 of the male member 3 is pushed into the receiving portion 28 of the plug 2, the protrusion 45 can pass through the notch 30 attached to the annular inward protruding portion 31 of the plug 2. There is no particular limitation as long as it is a simple shape. When a plurality of protrusions 45 are provided for the same reason, the position of the protrusion 45 needs to be provided at a position corresponding to the position of the notch 30 of the female member 1. It is relatively simple and preferable to arrange two pieces at intervals of 180 degrees. However, the number of notches 30 in the protrusion 45 and the annular inward protruding portion 31 is not particularly limited. The tip 41 has a head 42, an annular groove 47, and a through hole 48 in order from the tip. Next to the tip portion 41, a rod-like portion 49 is formed, in which a fluid passage 50 is provided from the vicinity of the head to the other end. The fluid passage 50 is connected to the outside through a through hole 48 in the head side opening. An annular groove portion 52 is provided between the rod-like portion 49 and the tip portion 41 so that an O-ring 51 can be attached. The O-ring 51 is not always necessary, but the O-ring 51 completely seals between the fluid passage 50 of the female member 1 and the outer peripheral surface of the rod-shaped portion 49 of the male member 3.

この発明の一実施の形態で用いられる連結システムの動作について図を用いて説明する。図１３は雌部材１の導通路４に雄部材３を挿入する状態の図１の連結システムの断面図である。図１３の状態から雌部材１の流体通路４内に雄部材３を挿入して押し込む場合、雄部材３の突起４５の位置とプラグ２の内側面２９に付設された環状内方突出部３１の切欠き３０の位置を合わせることにより、図１４に示すように、頭部４２が環状内方突出部３１を通過して、頭部上面４６と凹所３２が接するとともに、プラグ２の内側面２９と突起４５の当接面４３が当接する。   The operation of the connection system used in the embodiment of the present invention will be described with reference to the drawings. FIG. 13 is a cross-sectional view of the connection system of FIG. 1 in a state where the male member 3 is inserted into the conduction path 4 of the female member 1. When the male member 3 is inserted and pushed into the fluid passage 4 of the female member 1 from the state of FIG. 13, the position of the projection 45 of the male member 3 and the annular inward projecting portion 31 attached to the inner side surface 29 of the plug 2. By aligning the position of the notch 30, as shown in FIG. 14, the head 42 passes through the annular inward protruding portion 31, the head upper surface 46 and the recess 32 are in contact with each other, and the inner surface 29 of the plug 2. And the contact surface 43 of the protrusion 45 abuts.

さらに、雄部材3を押し込むと、図１５に示すように、雄部材３がプラグ２を押す力が、プラグ２の主嵌合部２２と雌部材１の開口部内面１３との係合する力を上回り、プラグ２が雌部材１の開口部１１から外れる。このとき、プラグ２の内側面２９に雄部材３の突起４５の当接面４３が当接する形状であるので、プラグ２が傾くことなく押し上げられる。雄部材３によりプラグ２を押し上げ、貫通孔４８が開口部１１の小径部１０よりも上方に位置すると容器内へ雄部材３の流体通路５０と貫通孔４８を介して容器内の液体、粉体の出し入れが行なえるようになる。   Further, when the male member 3 is pushed in, as shown in FIG. 15, the force by which the male member 3 pushes the plug 2 is the force with which the main fitting portion 22 of the plug 2 and the opening inner surface 13 of the female member 1 are engaged. And the plug 2 is detached from the opening 11 of the female member 1. At this time, since the contact surface 43 of the protrusion 45 of the male member 3 is in contact with the inner surface 29 of the plug 2, the plug 2 is pushed up without tilting. When the plug 2 is pushed up by the male member 3 and the through hole 48 is positioned above the small diameter portion 10 of the opening 11, the liquid and powder in the container are introduced into the container through the fluid passage 50 and the through hole 48 of the male member 3. You can go in and out.

次に図１５の状態から、雄部材３を引き抜く場合、図１６に示すように雄部材３を軸を中心に回転させ、雄部材３の突起４５の位置と雌部材２の環状内方突出部３１の切欠き３０の位置をずらすことにより、突起４５の係合部４３が環状内方突出部３１に係合し、プラグ２とともに確実に引っ張ることができる。プラグ２の主嵌合部２２が開口部１１に嵌る際、プラグ２の傾斜部２７は先端ほど漸次縮径されているため、小さな抵抗で開口部１１に進入する。また、開口部１１に深く進入するほど、開口部内面１３と強く接して、大きな抵抗がかかるため、雄部材３を引っ張るのに要する力が大きくなる。図１７に示すように、雌部材１の環状内方突出部１２にプラグ２の環状凹溝２４とが係合することにより、プラグ２と雌部材１が嵌合される。さらにプラグ２の停止面２６と開口部１１が接して停止し、再封止される。この時、図１８に示すように、雄部材３を軸を中心に回転させ、突起４５の位置と環状内方突出部３１の切欠き３０の位置を合わせ、さらに雄部材３を引っ張ることにより、図１９に示すように、頭部４２の突起４５が環状内方突出部３１を通り抜け、プラグ２の受容部２８から頭部４２が引き抜ける。   Next, when the male member 3 is pulled out from the state of FIG. 15, the male member 3 is rotated around the axis as shown in FIG. 16, and the position of the protrusion 45 of the male member 3 and the annular inward protruding portion of the female member 2 are rotated. By shifting the position of the notch 30 of 31, the engaging portion 43 of the protrusion 45 can be engaged with the annular inward protruding portion 31 and can be reliably pulled together with the plug 2. When the main fitting portion 22 of the plug 2 is fitted into the opening 11, the inclined portion 27 of the plug 2 is gradually reduced in diameter toward the tip, and therefore enters the opening 11 with a small resistance. Further, as the depth of entry into the opening 11 increases, the force required to pull the male member 3 increases because the resistance increases due to strong contact with the inner surface 13 of the opening. As shown in FIG. 17, the plug 2 and the female member 1 are fitted to each other by engaging the annular concave groove 24 of the plug 2 with the annular inward protruding portion 12 of the female member 1. Further, the stop surface 26 of the plug 2 and the opening 11 are brought into contact with each other and stopped and resealed. At this time, as shown in FIG. 18, the male member 3 is rotated around the axis, the position of the protrusion 45 is aligned with the position of the notch 30 of the annular inward projecting portion 31, and the male member 3 is further pulled, As shown in FIG. 19, the protrusion 45 of the head 42 passes through the annular inward protruding portion 31, and the head 42 is pulled out from the receiving portion 28 of the plug 2.

図２０は本発明のさらに他の実施の形態に係る連結システムのプラグ２の底面図である。図２1は連結部材の雄部材の正面図であり、図２２は連結部材の雄部材の側面図であり、図２３は連結部材の雄部材の平面図である。一実施の形態との大きな違いは、プラグ２の内側面２９に切欠き３０を施した環状内方突出部３１の代わりに突起６１を付設し、雄部材３の頭部４２に突起４５を形成させる代わりに当接面７１と係合面７２を備えた頭部４２に切欠き７３を設けたところである。   FIG. 20 is a bottom view of the plug 2 of the connection system according to still another embodiment of the present invention. FIG. 21 is a front view of the male member of the connecting member, FIG. 22 is a side view of the male member of the connecting member, and FIG. 23 is a plan view of the male member of the connecting member. A major difference from the embodiment is that a protrusion 61 is provided instead of the annular inward protrusion 31 having a notch 30 on the inner surface 29 of the plug 2, and a protrusion 45 is formed on the head 42 of the male member 3. Instead, the notch 73 is provided in the head 42 having the contact surface 71 and the engagement surface 72.

雄部材３を雌部材１の導通路４に挿入し、押し込む場合、雄部材１の頭部４２の切欠き７３の位置をプラグ２の突起６１の位置に合わせることにより、突起６１が切欠き７３を通り抜け、環状凹溝４７に入り、突起６１と切欠き７３の位置を移動させずらすことにより、係合面７２と突起６１が引っ掛かる。これにより、プラグ２と雄部材３が係合し、プラグ２を雄部材３とともに確実に引っ張ることが可能である。 When the male member 3 is inserted and pushed into the conduction path 4 of the female member 1, the protrusion 61 is notched 73 by aligning the position of the notch 73 of the head 42 of the male member 1 with the position of the protrusion 61 of the plug 2. The engagement surface 72 and the protrusion 61 are hooked by moving through and moving into the annular groove 47 and shifting the positions of the protrusion 61 and the notch 73. Thereby, the plug 2 and the male member 3 are engaged, and the plug 2 can be reliably pulled together with the male member 3.
