The body of the bag body is covered with a shrink body made of a shrink film in a cylindrical shape, and heat is applied from the outside to shrink the shrink body and tighten the body so that the bottoms of both ends are stretched. Therefore, the piercing tube can be easily pierced.

以下、本発明の実施の形態を、図面を用いて具体的に説明する。
先ず、図１〜図６に示す第１の実施の形態について説明すると、１は上端が開口する縦長の合成樹脂製の容器本体で、この容器本体１の上端開口部は容器本体１と同様の合成樹脂製からなり容器本体１の胴部１ａに被さる蓋体２によって閉じられ、容器を構成している。なお、蓋体２の下端内面には容器本体１の下端外面に形成されている雄ねじ部３に螺合する雌ねじ部４が形成されており、雌ねじ部４を雄ねじ部３に螺合させることにより容器本体１の上端が蓋体２で閉じられることになる。蓋体２の上端口部２ａには液体取り出し部となる液体取り出しポンプ５が螺合することにより装着される。液体取り出しポンプ５には前記容器本体１内に下向きに突出する突き刺しチューブ６を備え、この突き刺しチューブ６は容器本体１内にセットされる液体収納袋体７（詳細は後述する）の上端に突き刺さり、液体取り出しポンプ５の動作により液体収納袋体７内部の液体が液体取り出しポンプ５のノズル５ａより取り出されるようにした液体取り出し装置が構成される。 Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the first embodiment shown in FIG. 1 to FIG. 6 will be described. Reference numeral 1 denotes a vertically long synthetic resin container body whose upper end opens, and the upper end opening of the container body 1 is the same as that of the container body 1. It is made of a synthetic resin and is closed by a lid body 2 that covers the body portion 1a of the container body 1 to constitute a container. In addition, the internal thread part 4 screwed with the external thread part 3 currently formed in the lower end outer surface of the container main body 1 is formed in the lower end inner surface of the cover body 2, By screwing the internal thread part 4 to the external thread part 3, The upper end of the container body 1 is closed by the lid 2. A liquid take-out pump 5 serving as a liquid take-out portion is attached to the upper end opening 2a of the lid body 2 by screwing. The liquid take-out pump 5 includes a piercing tube 6 that protrudes downward into the container body 1, and this piercing tube 6 pierces the upper end of a liquid storage bag body 7 (details will be described later) set in the container body 1. The liquid take-out apparatus is configured such that the liquid inside the liquid storage bag body 7 is taken out from the nozzle 5 a of the liquid take-out pump 5 by the operation of the liquid take-out pump 5.

ところで、前記液体収納袋体７の袋本体８は合成樹脂フィルムを材料に用いて筒状となるように作られ、その胴部９の長さ方向両端である上下両端に、スタンドパックの形態の袋に備わる下端の底部の形をした底部１０を備え、またその長さ方向に沿う一側部の中央部に内容物の充填口１１を備えている。なお、内容物充填前は袋本体８が扁平状態であるがために前記底部１０も折り畳まれて膨らんだ状態とはなっていない。図中、１２は袋本体８のヒートシール部である。   By the way, the bag body 8 of the liquid storage bag body 7 is made to be cylindrical using a synthetic resin film as a material, and in the form of a stand pack at both upper and lower ends, which are both ends in the longitudinal direction of the trunk portion 9. A bottom 10 in the shape of the bottom of the bottom of the bag is provided, and a content filling port 11 is provided at the center of one side along the length direction. In addition, since the bag main body 8 is in a flat state before filling the contents, the bottom portion 10 is not folded and swollen. In the figure, 12 is a heat seal portion of the bag body 8.

上記の袋本体８の内部に内容物である洗剤やシャンプー、リンスなどの液体を充填するときは袋本体８の長さ方向が水平方向に向き、充填口１１が上に向くように袋本体８を位置決めし、かかる状態で充填口１１より内容物を充填するのである。内容物充填後は充填口１１の入口部をヒートシールにより閉じるのである。１３はそのヒートシール部である。   When filling the bag body 8 with a liquid such as detergent, shampoo, or rinse, which is the contents, the bag body 8 is oriented so that the length direction of the bag body 8 is horizontal and the filling port 11 is upward. In this state, the contents are filled from the filling port 11. After filling the contents, the inlet of the filling port 11 is closed by heat sealing. Reference numeral 13 denotes the heat seal portion.

袋本体８を長さ方向が水平方向に向くようにして内容物を充填するとき、始めは袋本体８は扁平状態であり、充填口１１より内容物を充填することにより袋本体８は徐々に膨らむことになるが、充填中において袋本体８は扁平状態に戻ろうと作用し、袋本体８の胴部９が完全な円筒状に近い形になるまで内容物を充填することは困難であり、胴部９や底部１０が弛んだ状態となる。   When the bag body 8 is filled with the contents so that the length direction is in the horizontal direction, the bag body 8 is initially flat and the bag body 8 is gradually filled by filling the contents from the filling port 11. It will swell, but during filling, the bag body 8 acts to return to a flat state, and it is difficult to fill the contents until the body portion 9 of the bag body 8 becomes a nearly cylindrical shape, The trunk | drum 9 and the bottom part 10 will be in the state which slackened.

つまり、内容物が充填された袋本体８を立てた状態で容器内にセットしたとき、袋本体８の胴部９や底部１０に張りがなく、前記液体取り出しポンプ５の突き刺しチューブ６で袋本体８の上端に位置する底部１０に突き刺すときに突き刺しチューブ６で底部１０が押されて沈むため、突き刺しチューブ６が底部１０に突き刺しにくいという問題がある。そこで、本実施の形態では内容物が充填された袋本体８の外側に袋本体８の外周の長さに合う内周を備えるようにシュリンクフィルムで筒状に作られた収縮体１４を用い、この収縮体１４を袋本体８の胴部９に被せ、外部から熱をかけて収縮体１４を収縮させて胴部９を締め付けることにより両端の底部１０が張った状態の液体収納袋体７が完成する。なお、この第１の実施の形態では袋本体８の胴部９の上下両端近傍部を除く範囲で収縮体１４が被せられている。   That is, when the bag body 8 filled with the contents is set in the container in an upright state, there is no tension on the body portion 9 and the bottom portion 10 of the bag body 8, and the bag body is inserted by the piercing tube 6 of the liquid take-out pump 5. When the bottom portion 10 located at the upper end of 8 is stabbed, the bottom portion 10 is pushed and sinks with the piercing tube 6, so that the piercing tube 6 is difficult to pierce the bottom portion 10. Therefore, in the present embodiment, the shrink body 14 made of a shrink film is used so as to have an inner circumference that matches the outer circumference of the bag body 8 on the outer side of the bag body 8 filled with the contents. The shrinkable body 14 is placed on the body portion 9 of the bag body 8, and the liquid storage bag body 7 in a state where the bottom portions 10 at both ends are stretched by contracting the shrinkage body 14 by applying heat from the outside and tightening the body portion 9. Complete. In the first embodiment, the contraction body 14 is covered in a range excluding the vicinity of the upper and lower ends of the body portion 9 of the bag body 8.

この液体収納袋体７は前記両端の底部１０が上下に位置するように立てた状態で容器本体１内にセットされ、上端口部２ａに液体取り出しポンプ５が螺合して装着された蓋体２によって容器本体１の上端を閉じる。そのとき、液体取り出しポンプ５から下向きに突出する突き刺しチューブ６を液体収納袋体７の袋本体８の上端に位置する底部１０に上から突き刺す。そのとき、前記上端に位置する底部１０は張った状態となっているので突き刺しチューブ６の突き刺しが容易に行なえることになる。   The liquid storage bag body 7 is set in the container body 1 in a state where the bottom portions 10 at both ends are positioned up and down, and a lid body in which a liquid take-out pump 5 is screwed and attached to the upper end opening portion 2a. 2 closes the upper end of the container body 1. At that time, the stab tube 6 protruding downward from the liquid take-out pump 5 is stabbed from above into the bottom 10 located at the upper end of the bag body 8 of the liquid storage bag body 7. At that time, since the bottom 10 located at the upper end is in a stretched state, the piercing tube 6 can be easily pierced.

ところで、前記収縮体１４の材料であるシュリンクフィルムとしては例えばポリスチレン、ポリエチレンテレフタレート、ポリオレフィン、ポリ塩化ビニルなどの熱により収縮するフィルムが使用される。このシュリンクフィルムからなる収縮体１４は機械から筒状に押し出されたフィルムを必要長さにカットして収縮体１４として使用するようにしても良く、あるいは平たいフィルムを筒状に曲げ、フィルムの両端を接着剤で接合したものやフィルムの両端をヒートシールで接合したものを収縮体１４として使用するようにしても良い。   By the way, as the shrink film which is a material of the contraction body 14, for example, a film that contracts by heat, such as polystyrene, polyethylene terephthalate, polyolefin, polyvinyl chloride, or the like is used. The shrink body 14 made of the shrink film may be used as the shrink body 14 by cutting a film extruded from a machine into a cylindrical shape, or by bending a flat film into a cylindrical shape, May be used as the contraction body 14 by bonding with a bonding agent or by bonding both ends of the film with heat sealing.

なお、液体収納袋体７には胴部９の長さ方向両端である上下両端にスタンドパックの形態の下端の底部の形を呈する底部１０を備えており、少なくとも上端に位置する底部１０は突き刺しチューブ６を突き刺しやすい材料を使用することが必要であるが、上下両端の底部１０共に突き刺しチューブ６を突き刺しやすい材料を使用することも可能で、これにより、液体収納袋体７を上下何れに向けても突き刺しチューブ６の突き刺しが可能となり、その結果液体収納袋体７の長さ方向の何れの一端が上端に位置するように容器内に液体収納袋体７をセットすることができて容器内へのセット時の方向性が無くなる。   The liquid storage bag body 7 is provided with a bottom portion 10 having a bottom shape in the form of a stand pack at both upper and lower ends, which are both ends in the length direction of the body portion 9, and at least the bottom portion 10 positioned at the upper end is pierced. It is necessary to use a material that can easily pierce the tube 6, but it is also possible to use a material that can easily pierce the tube 6 at both the bottom portions 10 at both the upper and lower ends. However, the piercing tube 6 can be pierced, and as a result, the liquid storage bag body 7 can be set in the container so that one end in the length direction of the liquid storage bag body 7 is positioned at the upper end. Directionality when set to is lost.

次に、図７および図８に示す第２の実施の形態について説明すると、前記第１の実施の形態では袋本体８の胴部９の上下両端近傍部を除く範囲で収縮体１４が被せられているが、第２の実施の形態では袋本体８の胴部９の上下方向全長に亘って収縮体１４が被せられている。他の構成は第１の実施の形態と同様である。   Next, the second embodiment shown in FIGS. 7 and 8 will be described. In the first embodiment, the contraction body 14 is covered in a range excluding the vicinity of the upper and lower ends of the body portion 9 of the bag body 8. However, in the second embodiment, the contraction body 14 is covered over the entire length of the body portion 9 of the bag body 8 in the vertical direction. Other configurations are the same as those of the first embodiment.
