Embodiments of the present invention will be specifically described below with reference to the drawings.
First, the first embodiment shown in FIGS. 1 to 7 will be described. Reference numeral 1 denotes a vertically long synthetic resin container body whose upper end is open, 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.

  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.

  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.

  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.

  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 this embodiment, a ring 14 made of synthetic resin or metal is put on the outside of the body 9 of the bag body 8 filled with the contents so that the bag body 8 filled with the contents is squeezed from the outside, and By tightening the portion 9, the liquid storage bag body 7 in a state where the bottom portions 10 at both ends are stretched is completed. The ring 14 is a one-piece ring, has a spring property, and has a property of restoring after spreading outward.

  As described above, the liquid storage bag body 7 in which the body portion 9 is squeezed by the ring 14 is set in the container main body 1 in a state where the bottom portions 10 at both ends are positioned up and down, and is placed in the upper end mouth portion 2a. The upper end of the container body 1 is closed by the lid body 2 to which the liquid take-out pump 5 is screwed. 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.

  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.

  Next, the second embodiment shown in FIGS. 8 and 9 will be described. In the first embodiment, both ends of the split ring 14 that squeezes the bag body 8 filled with the contents from the outside. However, in the second embodiment, both ends of the split ring 14 are joined to each other with the bag body 8 filled with the contents squeezed from the outside. As a coupling structure of both ends of the split ring 14, a hole 15 that opens in the thickness direction of the ring 14 is formed at one end of the ring 14 and the other end of the ring 14 is locked to the hole 15 from the inside. A locking claw 16 is formed, and the locking claw 16 is locked in the hole 15. Thus, if it is the structure which latches the both ends of the ring 14, the ring 14 does not need to be provided with the property to restore | restore, after spreading outside like 1st Embodiment. Conversely, the ring 14 of the second embodiment only needs to have a spring property that restores in a direction that spreads outward after the inner diameter is narrowed.

  Next, the third embodiment shown in FIGS. 10 and 11 will be described. In the second embodiment, both ends of the split ring 14 that squeezes the bag body 8 filled with the contents from the outside. As a coupling structure, a hole 15 that opens in the thickness direction of the ring 14 is formed at one end of the ring 14, and a locking claw 16 that locks the hole 15 from the inside at the other end of the ring 14, The locking claw 16 is locked to the hole 15, but in the third embodiment, a hole 17 that opens at one end of the ring 14 is formed and communicated with the hole 17. A hole 18 that opens on the outer surface of the ring 14 is formed in the vicinity of the hole 17, and a tapered locking claw 19 that is inclined so as to swell from the tip on the outer surface is formed on the other end of the ring 14. The locking claw 19 at the other end of the ring 14 is connected to the ring 14 The locking claw 19 is locked to the hole 18 by being inserted into the hole 17 opened at the end face of one end, and pushing the locking claw 19 so as to protrude from the hole 18 opening to the outer surface of the ring 14. . Thus, if it is the structure which latches the both ends of the ring 14, the ring 14 does not need to be provided with the property to restore | restore, after spreading outside like 1st Embodiment. On the contrary, the ring 14 of the third embodiment only needs to have a spring property that restores in the direction of spreading outward after the inner diameter is narrowed, similarly to the ring 14 of the second embodiment.

By the way, as in the first to third embodiments described above, the width of the ring 14 for tightening the trunk portion 9 so as to squeeze the bag body 8 from the outside may be appropriately determined according to the length of the trunk portion 9.
Further, instead of using the ring 14 as a fastening means, a string made of cloth or resin is used, the bag body filled with the contents is squeezed from the outside, and the bottom part of both ends is tightened by tightening the trunk part. It is also possible to provide a liquid storage bag that bulges outward.
