【０００８】
【発明の実施の形態】
以下、本発明の実施例の形態を図面を参照して説明する。
【０００９】
本発明のチューブ容器１は、チューブ容器本体２と、キャップ本体３と、補助蓋４とから構成している。
【００１０】
チューブ容器本体２は合成樹脂製で、弾性圧搾可能な胴部５上端から肩部６を介して口頚部７を起立して構成している。本実施例では、図３に示す如く、口頚部７外周にキャップ本体３の係止手段の一部としての横Ｌ字状をなす凹溝８を凹設している。
【００１１】
キャップ本体３及び補助蓋４は合成樹脂により一体に形成されたもので、キャップ本体３は、口頚部７外面へ、口頚部上端開口面を密閉するノズル９付きの第１頂壁10外周から垂設した、第１周壁11を嵌着させてチューブ容器本体２に固定している。図示例では、第１周壁11は内周壁11a と外周壁11b との二重筒状に形成しており、その内周壁11a 内面下部に突設した係合突起12を、凹溝８に上方から押し込んだ後回動して嵌合させ、抜け出しの防止を図りつつチューブ容器本体２に固定している。また、第１頂壁10下面から垂設したシール筒22を、口頚部７内面に密嵌してこの部分の液密性を図っている。
【００１２】
キャップ本体３の容器体への嵌合係止手段としては、上記したツイストロック式のものに限らず、例えば、図４に示す如き螺合や、図５に示す如き突条相互の乗り越え係合による係止方法を採用することができる。
【００１３】
また、キャップ本体３は、第１頂壁の外周部分を、第１頂壁とは異質の合成樹脂材で形成してリング状の破断帯13となし、また、破断帯13一部からつまみ片14を起立し、更に、つまみ片の一方側面側の破断帯部分に、該破断帯切り離し用肉薄線15を形成している。また、ノズル９は、リング状破断帯13が囲む第１頂壁10部分から起立させている。尚、図１の実施例では、破断帯13の外周縁、即ち、第１頂壁10外周部内縁と、異質の合成樹脂材で形成した第１頂壁部分との接合線ａを、口頚部７内方位置に設けているが、図８に示す如く、口頚部７外方でも良く、或いは図示しないが、口頚部上に位置させても良い。
【００１４】
補助蓋４は、ノズル９上端開口面を閉塞する第２頂壁16外周から第１頂壁10の外周部上部へ載置させた第２周壁17を垂下し、該第２周壁17の下端部と第１周壁11の後部とを肉薄ヒンジ18で連結している。また、第２頂壁16裏面中央からはノズル９外周に嵌脱が可能に嵌合させた嵌合筒19を垂設し、また、その内方にはノズル９内周に密嵌する短いシール筒20を突設している。
【００１５】
上記の如きキャップ本体３及び補助蓋４は、例えば、インサート成形等により異材質の破断帯13及びつまみ片14部分と一体に成形することができる。
【００１６】
上記の如く構成したチューブ容器１を使用する場合は、補助蓋４を開いてチューブ容器本体２の胴部５を圧搾し、ノズル９から液を押し出して使用する。そして、収納液の量が極めて少なくなり、口頚部７乃至肩部６部分にしか殆ど液が存在しない状態で、胴部５の圧搾により殆どノズル９から液の押し出しができなくなった際に、つまみ片14をつかんで引き上げれば、破断帯13は肉薄線15の部分から破断し、その内方の第１頂壁部分を分離して大きな開口があくため、残った液を指等で容易に取り出すことができる。
【００１７】
図６は本発明の他の実施例を示すもので、本実施例では、図１の実施例に於けるキャップ本体３の一部の構成を変えたものである。本実施例では、キャップ本体３の口頚部７内面が囲む第１頂壁10部分にノズル９を付設するとともに、該頂壁部分を第１頂壁外周部とは異質の合成樹脂材で形成し、また、異質の合成樹脂材で形成した第１頂壁部分の外周一部からつまみ片14を起立し、これら異材質の合成樹脂材で形成された破断部Ａを設けている。その他の構成は図１の実施例と同様である。また、図６の実施例では、破断部Ａの外周縁、即ち、接合線ａを口頚部７内方位置に設けているが、図９が示す如く、口頚部７上に位置させても良く、或いは図示しないが口頚部７外方に位置させても良い。
【００１８】
図７は本発明の更に他の実施例を示すもので、本実施例では、口頚部７の上部内面との間に小間隙をおいて、口頚部７の下部内面から内筒21を起立し、該内筒上端面の内周縁よりも外方に、第１頂壁10外周部内縁と、異質の合成樹脂材で形成した第１頂壁部分との接合線ａを位置させている。この内筒21外表面はできるだけ滑らかな形状とすると良い。この様に構成することにより、破断帯13を破断した切断位置を指から保護してカット面で指等を切らない様構成している。その他の構成は図１の実施例と同様である。尚、この内筒の構成は図６の実施例にも適用することができる。
【００１９】
【発明の効果】
以上説明した如く本発明のチューブ容器は、既述構成としたことにより、チューブ容器体内に残って取り出し難くなった液を極めて簡単な方法で、殆ど残らず取り出すことができるため経済的であり、その構造も極めてシンプルで特別の設備を必要とせず、容易に製造できる利点も兼ね備えている。
【００２０】
また、口頚部の上部内面との間に小間隙をおいて、口頚部の下部内面から内筒を起立し、内筒上端面の内周縁よりも外方に、第１頂壁外周部内縁と、異質の合成樹脂材で形成した第１頂壁部分との接合線を位置させてなるものにあっては、破断帯や破断部等の切断除去により露出するカット面が、内筒の存在で手等に極力触れない様になり、手の指を切る等の不都合を防止できるものである。

[0010]
The tube container main body 2 is made of a synthetic resin, and is configured to stand up from the upper end of the body portion 5 that can be elastically squeezed through the shoulder portion 6 to the mouth and neck portion 7. In this embodiment, as shown in FIG. 3, a concave groove 8 having a lateral L-shape as a part of the locking means of the cap body 3 is provided in the outer periphery of the neck portion 7.
[0011]
The cap body 3 and the auxiliary lid 4 are integrally formed of a synthetic resin, and the cap body 3 is suspended from the outer periphery of the first top wall 10 with the nozzle 9 that seals the upper end opening surface of the mouth neck portion to the outer surface of the mouth neck portion 7. The provided first peripheral wall 11 is fitted and fixed to the tube container main body 2. In the illustrated example, the first peripheral wall 11 is formed in a double cylinder shape of an inner peripheral wall 11a and an outer peripheral wall 11b, and an engaging projection 12 projecting from the lower inner surface of the inner peripheral wall 11a is formed in the concave groove 8 from above. After being pushed in, it is turned and fitted to be fixed to the tube container main body 2 while preventing it from coming out. Further, a seal cylinder 22 suspended from the lower surface of the first top wall 10 is tightly fitted to the inner surface of the mouth-and-neck portion 7 to achieve liquid-tightness at this portion.
[0012]
The means for fitting and locking the cap main body 3 to the container body is not limited to the above-described twist lock type. For example, the screw engagement as shown in FIG. 4 or the overhang engagement between the protrusions as shown in FIG. The locking method by can be adopted.
[0013]
The cap body 3 is formed of a synthetic resin material different from that of the first top wall at the outer peripheral portion of the first top wall to form a ring-shaped fracture band 13. 14 is further erected, and further, the breaking band separating thin line 15 is formed in the breaking band portion on one side of the knob piece. Further, the nozzle 9 is erected from the first top wall 10 portion surrounded by the ring-shaped fracture band 13. In the embodiment of FIG. 1, the joint line a between the outer peripheral edge of the fracture band 13, that is, the outer periphery of the first top wall 10 and the first top wall portion formed of a different synthetic resin material, 7 is provided at the inner position, but as shown in FIG. 8, it may be located outside the mouth-and-neck portion 7, or may be located on the mouth-and-neck portion, although not shown.
[0014]
The auxiliary lid 4 hangs down from the outer periphery of the second top wall 16 that closes the upper end opening surface of the nozzle 9 to the upper part of the outer periphery of the first top wall 10, and the lower end of the second peripheral wall 17.

[0015]
The cap body 3 and the auxiliary lid 4 as described above can be formed integrally with the broken band 13 and the knob piece 14 of different materials by, for example, insert molding.
[0016]
When the tube container 1 configured as described above is used, the auxiliary lid 4 is opened to squeeze the body part 5 of the tube container body 2 and the liquid is pushed out from the nozzle 9 for use. When the amount of stored liquid is extremely small and almost no liquid is present only in the mouth-neck portion 7 to the shoulder portion 6, it becomes impossible to push out the liquid from the nozzle 9 by pressing the trunk portion 5. If the piece 14 is grasped and pulled up, the breaking band 13 breaks from the thin wire 15 portion, and the inner top first wall portion is separated to open a large opening so that the remaining liquid can be easily removed with a finger or the like. It can be taken out.
[0017]
FIG. 6 shows another embodiment of the present invention. In this embodiment, the configuration of a part of the cap body 3 in the embodiment of FIG. 1 is changed. In this embodiment, the nozzle 9 is attached to the first top wall 10 portion surrounded by the inner surface of the mouth neck portion 7 of the cap body 3, and the top wall portion is formed of a synthetic resin material different from the outer periphery of the first top wall. Further, a knob piece 14 is erected from a part of the outer periphery of the first top wall portion formed of a different synthetic resin material, and a fracture portion A formed of these different synthetic resin materials is provided. Other configurations are the same as those of the embodiment of FIG. Further, in the embodiment of FIG. 6, the outer peripheral edge of the rupture portion A, that is, the joining line a is provided at the inner position of the mouth-and-neck portion 7, but may be located on the mouth-and-neck portion 7 as shown in FIG. Alternatively, although not shown, it may be positioned outside the mouth-and-neck portion 7.
