Description

【０００１】
【発明の属する技術分野】
本発明は、チューブ容器に関する。
【０００２】
【従来の技術】
例えば、実開平３−３８７４７号には、胴部２の上端面を上板で閉塞すると共に、該上板前部に注出口を穿設し、かつ上板後面に開口させて上板後部に横穴を穿設したチューブ容器本体と、該チューブ容器本体の頂部に、頂壁周縁から垂設した栓棒を上記注出口に嵌合させ、更に周壁の後部下端から、三点ヒンジ機構を介して取付板を前方へ突出し、該取付板を上記横穴内へ嵌着させたキャップとからなるキャップ付きチューブ容器が開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上述した従来のチューブ容器では胴部を圧搾して、容器本体内の内容物を注出口から注出するため、上記圧搾が強すぎると内容物が余分に注出されて、無駄が生じるという問題があった。又内容物の漏出や変質を防止するために、キャップを用いて注出口を閉塞しているから、注出前後にキャップの開閉操作が必要となり、面倒であった。
【０００４】
本発明は、内容物が余分に注出されることがない、しかも注出前後にキャップの開閉操作を必要とせず、内容物の漏出や変質を防止できる操作の簡単なチューブ容器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、第１の手段としては、可撓性に富む薄肉の胴部３から肩部４を介して口頸部５を起立し、該口頸部上端から内向きフランジ６を介して第１嵌合壁７を起立すると共に、該第１嵌合壁の下部内面を、中央部に吸込み弁孔８を有する頂板９で閉塞し、かつ上記第１嵌合壁７前部に切欠き１０を穿設した容器本体２と、上記第１嵌合壁７内面へ、気密に、弾性ある第２嵌合壁１６を嵌着すると共に、上記切欠き内に位置する第２嵌合壁部分の左右両側部に、一対の割溝１７ａ，１７ｂを穿設して該割溝間の第２嵌合壁部分を吐出弁板１８とし、又第２嵌合壁上端から斜下内方へ、複数の弾性連結片１９…を突出して、これ等弾性連結片１９…の各先端に付設した吸込み弁板２０で上記吸込み弁孔８を閉塞する弾性弁部材１５と、上記第１嵌合壁７外面へ気密に、かつ抜出し不能に第３嵌合壁２６を嵌着し、該嵌合壁上端から、第２嵌合壁上面に載置させて内向きフランジ２７を突出すると共に、該内向きフランジ内周縁から弾性変形可能なドーム状壁２８を張設し、かつ上記切欠き１０前方の第３嵌合壁部分を開口して該開口周縁からノズル３１を前方へ突設するキャップ部材２５とからなり、上記吐出弁板１８後方の頂板部分上面からは、上記一対の割溝１７ａ，１７ａを閉塞し、かつ吐出弁板後面へ気密に係合させて凹字状壁１２を起立し、上記吸込み弁板２０と吸込み弁孔８とで吸込弁２２を、又上記吐出弁板１８と凹字状壁の凹部１１とで吐出弁２１を形成した。
【０００６】
また第２の手段としては、第１の手段を有すると共に、上記ノズル３１の前端面に、該ノズルの注出孔閉塞用のシール材３３を剥離可能に固着した。
【０００７】
【発明の実施の形態】
図１から図６は本発明のチューブ容器１を示す。該チューブ容器は容器本体と、弾性弁部材、及びキャップ部材とからなり、これら各部材を合成樹脂材で成形している。
【０００８】
容器本体２は図１が示すように、可撓性に富む薄肉の胴部３から肩部４を介して口頸部５を起立し、該口頸部上端から内向きフランジ６を介して第１嵌合壁７を起立すると共に、第１嵌合壁の下部内面を、中央部に吸込み弁孔８を有する頂板９で閉塞し、かつ上記第１嵌合壁７前部に切欠き１０を穿設している。該切欠き後方の頂板部分上面からは、後述する吐出弁板の後面へ気密に係合する凹字状壁１２を起立しており、該凹字状壁は図３が示すように、上部の左右方向中間部に上記切欠き１０より１回り小さな凹部１１を穿設している。
【０００９】
図４は弾性弁部材１５を示す。該弾性弁部材は第１嵌合壁７内面へ気密に嵌着する、弾性に富む第２嵌合壁１６の前部に、一対の割溝１７ａ，１７ｂを穿設し、該割溝間の第２嵌合壁部分を吐出弁板１８とし、又上記第２嵌合壁の上端から斜下内方へ、複数の弾性連結片１９…を突出して、これ等弾性連結片１９…の各先端に、これ等が共有する吸込み弁板２０を付設している。
【００１０】
上記一対の割溝１７ａ，１７ｂを切欠き１０内に位置させて、図５が示すように第２嵌合壁１６を第１嵌合壁７内面へ気密に嵌着すると、上記吐出弁板後面は凹字状壁１２前面に気密に係合して凹部１１を閉塞し、又一対の割溝１７ａ，１７ｂは凹字状壁１２で閉塞され、更に上記吸込み弁板２０は図１が示すように、吸込み弁孔８を閉塞する。したがって、上記弾性弁部材１５は上述したように容器本体２に組み込まれると、上記吐出弁板１８が凹字状壁の凹部１１とで吐出弁２１を、又上記吸込み弁板２０が吸込み弁孔８とで吸込弁２２を形成する。なお、図示例では吐出弁板１８の肉厚を、第２嵌合壁１６の肉厚より肉薄にし、小さな圧力の変化に応答して上記凹部１１を開放することができるようにしている。
【００１１】
キャップ部材２５は、上記第１嵌合壁７外面へ気密に、かつ抜出し不能に第３嵌合壁２６を嵌着し、該嵌合壁上端から、第２嵌合壁上面へ気密に載置させて内向きフランジ２７を突出すると共に、該内向きフランジ内周縁から弾性変形可能なドーム状壁２８を張設して、該ドーム状壁下方の閉塞空間を加圧室２９とし、又切欠き１０前方の第３嵌合壁部分に開口３０を穿設し、該開口周縁から、ノズル３１を前方へ突設している。該ノズルの前端には図２が示すように、該ノズルの注出孔３２を閉塞するシール材３３が剥離可能に溶着されている。なお、上記シール材３３は接着材を介して貼着してもよい。また上記ノズル３１は図示例のように斜上前方に突出させてもよい。この場合には容器本体の頂板９を斜前上方の傾斜面とするとよい。
【００１２】
以下、上記チューブ容器１の作用について説明する。まずシール材３３をノズル３１から剥離し、キャップ部材２５が下向くようにチューブ容器１を逆さまにする。該状態でドーム状壁２８を押圧変形すると、加圧室２９内が高圧化し、これにより、吐出弁２１が開弁して加圧室２９内の空気が放出され、高圧化が解消される。該高圧化の解消に伴い上記吐出弁２１は閉弁する。この後、ドーム状壁２８の押圧を開放すると、ドーム状壁２８が弾性復元し、加圧室２９内の負圧化により吸込弁２２が開弁して、容器本体２内の内容物が加圧室２９内に流入する。該流入は加圧室２９内の負圧化が解消されるまで行われて、上記吸込弁２２が閉弁する。
【００１３】
該状態でドーム状壁２８を再び押圧変形すると、上述したように吐出弁２１が開弁して、加圧室２９内の内容物は吐出弁２１，ノズル３１を通り、注出孔３２から注出され、ドーム状壁２８の押圧解除で、ドーム状壁２８が弾性復元して容器本体２内の内容物は加圧室２９内に流入する。よって以後の注出はドーム状壁２８を１回押圧変形するだけで可能となる。
【００１４】
【発明の効果】
請求項１記載のチューブ容器１は既述構成とするもので、容器本体の第１嵌合壁７外面へ気密に、弾性弁部材の弾性ある第２嵌合壁１６を嵌着させて、吐出弁２１及び吸込弁２２を形成するようにし、しかも該弾性弁部材を、上記第２嵌合壁１６の前部に、一対の割溝１７ａ，１７ｂを穿設して該割溝間の第２嵌合壁部分を吐出弁板１８とし、又第２嵌合壁上端から斜下内方へ、複数の弾性連結片１９…を突出して、これ等弾性連結片１９…の各先端に、これ等先端が共有する吸込み弁板２０を付設した、即ち吐出弁板１８と吸込み弁板２０とを一体化した簡単な構成にしたから、その弁機構を安価なものにでき、よって、その製造コストを低減することができる。
【００１５】
又上記チューブ容器１は上記吐出弁２１をドーム状壁２８の押圧変形により、又上記吸込弁２２をドーム状壁２８の弾性復元により、それぞれ開弁するようにし、加圧室２９内へ容器本体２内の内容物を一旦流入させ、しかる後、加圧室の内容物をノズル３１から注出するようにして、１回の注出量を加圧室の変形容積としたから、余分な内容物が注出するのを防止することができる。更に上記吐出弁板１８は弾性により凹字状壁の凹部１１を閉塞しているから、加圧室２９内の内容物は外気や埃から遮断されるようになり、よって従来のチューブ容器のように注出口をキャップ等を用いて閉塞しなくても、内容物の漏出や変質を防止することができる。
【００１６】
請求項２記載のチューブ容器１は、請求項１記載の効果を有すると共に、ノズル３１の前端面に、該ノズルの注出孔３２閉塞用のシール材３３を剥離可能に固着したから、輸送や保管時にドーム状壁２８が誤って押圧されても、ノズル３１から内容物が注出されるのを防止でき、更に上記シール材をバージンシールとして用いることで、シュリンクパック等の特殊包装をしなくても内溶液の未使用を表現することができる。

A plurality of elastic connecting pieces 19 project outward, and an elastic valve member that closes the suction valve hole 8 with a suction valve plate 20 attached to each end of the elastic connecting pieces 19. 5 and the third fitting wall 26 is airtightly and non-extractably fitted to the outer surface of the first fitting wall 7 and is placed on the upper surface of the second fitting wall from the upper end of the fitting wall to face inward. A flange 27 is projected, an elastically deformable dome-shaped wall 28 is extended from the inner peripheral edge of the inward flange, and a third fitting wall portion in front of the notch 10 is opened to open the nozzle 31 from the opening peripheral edge. And a cap member 25 projecting forward. The pair of split grooves 17a, 17a are closed from the upper surface of the top plate portion behind the discharge valve plate 18 and airtightly engaged with the rear surface of the discharge valve plate. The concave wall 12 is raised, and the suction valve plate 20 and the suction valve hole 8 form the suction valve 22, and the discharge valve plate 18 and the concave portion 11 of the concave wall form the discharge valve 21.
[0006]
The second means includes the first means, and a sealing material 33 for closing the injection hole of the nozzle is detachably fixed to the front end face of the nozzle 31.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
1 to 6 show a tube container 1 of the present invention. The tube container includes a container body, an elastic valve member, and a cap member, and these members are formed of a synthetic resin material.
[0008]
As shown in FIG. 1, the container body 2 stands up a mouth and neck 5 from a thin flexible body 3 via a shoulder 4, and from the upper end of the mouth and neck via an inward flange 6. While the first fitting wall 7 stands up, the lower inner surface of the first fitting wall is closed with a top plate 9 having a suction valve hole 8 in the center, and a notch 10 is formed in the front of the first fitting wall 7. Has been drilled. From the upper surface of the top plate portion behind the notch, an upright concave wall 12 is formed, which airtightly engages with a rear surface of a discharge valve plate to be described later. As shown in FIG. A recess 11 that is one size smaller than the notch 10 is formed in the middle part in the left-right direction.
[0009]
FIG. 4 shows the elastic valve member 15. The elastic valve member is provided with a pair of split grooves 17a and 17b at the front of the second elastic fitting wall 16 which is airtightly fitted to the inner surface of the first fitting wall 7. The second fitting wall portion is a discharge valve plate 18, and a plurality of elastic connecting pieces 19 project from the upper end of the second fitting wall inward and obliquely downward. In addition, a suction valve plate 20 shared by these components is additionally provided.
[0010]
When the pair of split grooves 17a and 17b are positioned in the notch 10 and the second fitting wall 16 is airtightly fitted to the inner surface of the first fitting wall 7 as shown in FIG. Is airtightly engaged with the front surface of the concave wall 12 to close the concave portion 11, the pair of split grooves 17a and 17b are closed by the concave wall 12, and the suction valve plate 20 is as shown in FIG. Then, the suction valve hole 8 is closed. Therefore, when the elastic valve member 15 is incorporated in the container body 2 as described above, the discharge valve plate 18 and the concave portion 11 of the concave wall form the discharge valve 21 and the suction valve plate 20 forms the suction valve hole. 8 together with the suction valve 22. In the illustrated example, the thickness of the discharge valve plate 18 is made thinner than the thickness of the second fitting wall 16 so that the concave portion 11 can be opened in response to a small change in pressure.
[0011]
The cap member 25 air-tightly fits the third fitting wall 26 to the outer surface of the first fitting wall 7 so as not to be pulled out, and mounts the air-tightly from the upper end of the fitting wall to the upper surface of the second fitting wall. Then, an inward flange 27 is projected, and a dome-shaped wall 28 that can be elastically deformed is extended from an inner peripheral edge of the inward flange, so that a closed space below the dome-shaped wall is formed as a pressure chamber 29, and a notch is formed. An opening 30 is formed in the third fitting wall portion 10 at the front, and a nozzle 31 protrudes forward from the periphery of the opening. As shown in FIG. 2, a sealing material 33 for closing the injection hole 32 of the nozzle is detachably welded to the front end of the nozzle. Note that the seal material 33 may be attached via an adhesive. Further, the nozzle 31 may be projected obliquely upward and forward as in the illustrated example. In this case, it is preferable that the top plate 9 of the container main body is an inclined front upper surface.
[0012]
Hereinafter, the operation of the tube container 1 will be described. First, the sealing material 33 is peeled off from the nozzle 31, and the tube container 1 is turned upside down so that the cap member 25 faces downward. When the dome-shaped wall 28 is pressed and deformed in this state, the pressure in the pressurizing chamber 29 is increased, whereby the discharge valve 21 is opened and the air in the pressurized chamber 29 is released, so that the increase in pressure is eliminated. With the elimination of the high pressure, the discharge valve 21 closes. Thereafter, when the pressing of the dome-shaped wall 28 is released, the dome-shaped wall 28 is elastically restored, the suction valve 22 is opened by the negative pressure in the pressurizing chamber 29, and the contents in the container body 2 are added. It flows into the pressure chamber 29. The inflow is performed until the negative pressure in the pressurizing chamber 29 is eliminated, and the suction valve 22 is closed.
[0013]
When the dome-shaped wall 28 is again pressed and deformed in this state, the discharge valve 21 is opened as described above, and the contents in the pressurizing chamber 29 pass through the discharge valve 21 and the nozzle 31 and are discharged from the discharge hole 32. When the dome-shaped wall 28 is released and the dome-shaped wall 28 is released, the dome-shaped wall 28 is elastically restored, and the contents in the container body 2 flow into the pressurizing chamber 29. Therefore, the subsequent pouring is possible only by pressing and deforming the dome-shaped wall 28 once.
[0014]
【The invention's effect】
The tube container 1 according to the first aspect has the above-described configuration, and the second fitting wall 16 having an elastic valve member is fitted airtightly to the outer surface of the first fitting wall 7 of the container body, and discharge is performed. A valve 21 and a suction valve 22 are formed, and the elastic valve member is provided with a pair of split grooves 17a and 17b at a front portion of the second fitting wall 16 to form a second groove between the split grooves. The fitting wall portion is formed as a discharge valve plate 18, and a plurality of elastic connecting pieces 19 project from the upper end of the second fitting wall inward and obliquely downward. Since the suction valve plate 20 shared by the distal end is provided, that is, the discharge valve plate 18 and the suction valve plate 20 are integrated into a simple structure, the valve mechanism can be inexpensive, and the manufacturing cost can be reduced. Can be reduced.
[0015]
The tube container 1 opens the discharge valve 21 by pressing deformation of the dome-shaped wall 28, and opens the suction valve 22 by elastic restoration of the dome-shaped wall 28. The contents in the pressurizing chamber were once flowed in, and thereafter, the contents in the pressurizing chamber were discharged from the nozzle 31 so that the amount of one discharge was set as the deformation volume of the pressurizing chamber. Objects can be prevented from being poured out. Further, since the discharge valve plate 18 closes the concave portion 11 of the concave wall by elasticity, the contents in the pressurizing chamber 29 are shielded from the outside air and dust, and therefore, like a conventional tube container. Even if the spout is not closed using a cap or the like, leakage and alteration of the contents can be prevented.
[0016]
The tube container 1 according to the second aspect has the effect according to the first aspect, and the sealing member 33 for closing the discharge hole 32 of the nozzle is fixed to the front end surface of the nozzle 31 in a peelable manner, so that the tube container 1 can be transported. Even if the dome-shaped wall 28 is erroneously pressed during storage, it is possible to prevent the contents from being poured out from the nozzle 31. Further, by using the sealing material as a virgin seal, it is possible to eliminate the need for special packaging such as a shrink pack. Can also express the unused of the internal solution.
