  However, as shown in Patent Document 1, even if the tip of the suction pipe of the dispenser is curved, there is a problem that the liquid remaining in the bottom of the container can not be sucked up to the end depending on the bending direction or the like. In addition, there is also a problem that the work of refilling the refilling pouch container with the empty bottle is time-consuming.

  An object of the present invention is to provide a pump which can solve the above-mentioned problems and can be directly attached to a commercially available refilling pouch container until the liquid in the pouch container runs out.

  A pump according to the present invention for achieving the above object is a pouch container having a container main body formed of a flexible synthetic resin sheet, and a spout projecting upward from the top surface of the container main body. A pump that can be attached, comprising: a cap portion that can be screwed to the spout portion; a discharge portion slidably disposed vertically with respect to the cap portion; and a valve that can extend and contract continuously with the lower end of the discharge portion It is characterized by being comprised from a body part and a suction pipe which follows the lower end of the valve body part.

  According to the pump of the present invention, by directly attaching to a commercially available pouch container for refilling and using it, the operation of refilling the liquid to the bottle does not occur. In addition, it is not necessary for the tip of the suction pipe to reach the bottom of the container body, and it is possible to use an appropriately sized pouch container until there is no liquid in the container body.

It is a perspective view of the pouch container which attached the pump. It is sectional drawing of the side of a pouch container. It is sectional drawing of the pouch container at the time of pressing down a press piece part.

The present invention will be described in detail based on the illustrated embodiments.
FIG. 1 is a perspective view of a pouch container attached with a pump, FIG. 2 is a cross-sectional view of the side of the pouch container, and FIG. 3 is a cross-sectional view of the pouch container when the pressing piece is pressed.

  The pump 1 is made of a synthetic resin, and includes a cap portion 2 which can be screwed to the spout portion of the pouch container B, a discharge portion 3 slidably disposed vertically with respect to the cap portion 2, and It comprises a valve body 4 which is continuous with the lower end and which can be expanded and contracted, and a suction pipe 5 which is continuous with the lower end of the valve body 4.

  The cylindrical cap portion 2 is provided in the vicinity of a first inner screw portion 2a provided on the inner wall on the lower end side, an outer screw portion 2b provided on the outer wall on the upper end side, and the outer screw portion 2b. And a through hole 2c.

  The discharge part 3 comprises a tubular discharge pipe 3a inserted into the through hole 2c, and a pressing piece 3b obtained by bending the discharge pipe 3a in an L shape, and the pressure piece 3b has a discharge port at the tip in the horizontal direction 3c is provided. A cylindrical portion 3d is vertically provided below the pressing piece 3b, and a second inner screw portion 3e is provided on the inner wall of the cylindrical portion 3d. The second internally threaded portion 3 e and the externally threaded portion 2 b of the cap portion 2 can be screwed together.

  In the valve body 4, a cylindrical first valve portion 4 a for flowing the fluid from the lower side to the upper side to the upper end side and preventing backflow of the fluid from the upper side to the lower side, and a lower side to the upper side And a ball-shaped second valve portion 4b for flowing the fluid against it and preventing the backflow of the fluid from the upper side to the lower side.

  An upper cover 4c is disposed between the first valve 4a and the second valve 4b, and an elastic member 4d, which is a spring, is disposed below the upper lid 4c. As long as the first valve portion 4a and the second valve portion 4b have a structure that prevents the backflow of fluid, an appropriate valve structure can be adopted.

  The suction pipe 5 is a straight pipe, and when the pump 1 is attached to the pouch container B, the suction pipe 5 has a length reaching near the bottom of the pouch container B. In addition, in order to enable attachment to a commercially available pouch container for refilling, the diameter of the suction pipe 5 and the valve body portion 4 is a narrow shape of about 1 cm.

  The pouch container B, to which the pump 1 can be attached, protrudes upward from the container body B1 formed of a flexible synthetic resin sheet, and the top surface B2 of the container body B1, and the external thread B3 is formed on the outer surface. It is comprised from the equipped spout part B4. As shown in FIG. 1, the pouch container B can be maintained in the upright state by the bottom of the container body B1.

  The container body B1 is filled with a liquid such as shampoo or body soap, and is marketed as a refill pouch container in a state where a cap member (not shown) is screwed to the external thread B3.

  When using the pump 1, the cap member of the container body B1 is removed, and the suction pipe 5 is inserted into the spout B4. Then, the first internally threaded portion 2a of the cap portion 2 is screwed to the externally threaded portion B3 of the spout portion B4, and the pump 1 and the pouch container B are integrated.

  At the same time, the screwed state between the externally threaded portion 2b of the cap portion 2 before use of the pump 1 and the second internally threaded portion 3e of the discharge portion 3 is released. This screwing state is for space saving, and by releasing the screwing state, the discharge part 3 is moved upward by the elastic force of the compressed elastic member 4d.

  And the state of FIG. 3, FIG. 2 will be repeated by pressing and releasing press of the press piece part 3b. The upper lid portion 4c and the first valve portion rise when the pressure piece 3b returns upward due to the elastic force of the compressed elastic member 4d by releasing the pressure after the first depression of the pressure piece 3b with the hand. At the same time as the flow path is closed by the engagement with 4a, the ball body, which is the second valve portion 4b, floats, whereby the liquid is sucked up into the valve body portion 4 through the second valve portion 4b.

  Subsequently, when the pressing piece portion 3b is pressed against the elastic force of the elastic member 4d, the ball body as the second valve portion 4b closes the flow path by its own weight and pressure, and at the same time, it is possible to vertically impulsively move the first The pressure in the valve body 4 raises the pressure in the valve body 4 and the liquid in the valve body 4 is pushed out into the discharge pipe 3a through the space between the first valve 4a and the upper lid 4c. Then, by repeatedly pressing and releasing the pressing piece 3b, the liquid pushed out to the discharge pipe 3a is discharged from the discharge port 3c without flowing back into the valve body 4.

  The container body B1 formed of a flexible synthetic resin sheet will be entirely deflated with repeated discharge of the liquid. Since air does not flow into the container body B1 by the first valve portion 4a and the second valve portion 4b, the tip of the suction pipe 5 is always in contact with the liquid, and the container body B1 is It can be used until the liquid runs out.

  However, since it becomes difficult to stand the pouch container B as the liquid in the container body B1 decreases, it is preferable to use the pouch container B in a dedicated storage case.

  As described above, by directly attaching the pump 1 of the present invention to a commercially available refilling pouch container and using it, the operation of refilling the liquid with the bottle does not occur. Further, it is not necessary for the tip of the suction pipe 5 to reach the bottom of the container body B1, and if the shape of the spout B4 can be screwed to the cap 2, the pouch container B of an appropriate size It can be used until the liquid in the container body B1 is exhausted.
