Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a liquid pouring pump.

[0002]

[Prior art] [Problems to be solved by the device]

  Conventionally, the liquid in the container body is moved to the cylinder by vertically moving the push-down head. A liquid pouring pump configured so that it sucks up inside and pours out from the nozzle hole of the head is used. Is used. These are attached at the lower end by a mounting cap that fits into the mouth neck of the container. While hanging the cylinder inside the container, press down the head with the nozzle at the top. It is configured so as to be vertically movable above the mounting cap.

[0003]   When using this type of conventional pump, some force is required to push down the head, Especially when the container is large or the content liquid has a high viscosity, this tendency is remarkable. is there.

[0004]   The present invention has been made in view of the above points, and it is possible to press down the head with a small force. It proposes an easy-to-use liquid pouring pump.

[0005]

[Means for Solving the Problems]

  In order to solve the above problems, the liquid pouring pump according to the first aspect of the present invention is provided outside the neck of the container body. With the mounting cap 4 fitted around the circumference, the cylinder 5 at the lower end is suspended in the container body. In addition, the push-down head 7 with the nozzle 6 at the upper end is moved upward above the mounting cap 4. Attached to the container body by protruding vertically so that it can be moved vertically, A liquid pouring pump constructed so that the liquid in the container is poured out from the nozzle hole of the head. And the push-down member 3 for pushing down the push-down head 7 is detachably mounted. And push down the push-down member 3 from the rear end of the mounting cap 4 in a detachable manner. The combined flat C-shaped mounting portion 9 and the columnar support integrally extending upward from the mounting portion 9. The holding part 10 and the rear end are integrally connected to the upper end of the supporting part 10 via a thin hinge 11. And a push-down plate 12 whose front end is extended to the front upper side of the head 7.

[0006]   In the liquid pouring pump according to the second aspect of the present invention, the front portion of the push-down plate 12 is bent downward. And move the nozzle 6 up and down through the nozzle insertion hole 17 formed in the center of the bent portion. 2. The liquid pouring device according to claim 1, wherein the liquid pouring is made possible and the lower end of the bent portion is a finger-holding lever 18. Configured as a delivery pump.

[0007]

[Action]

  If the tip of the upper surface of the push-down plate 12 is pushed downward from the state shown in FIG. The distance between the thin hinge 11 and the pressing protrusion 13 that is the point of action is less than the distance between the thin hinge 11 and the force point. Since the distance between the push-up parts is longer, it is far more than when the head 5 is pushed down directly. The head 5 can be pushed down with a small force.

[0008]   In the embodiment shown in FIGS. 7 to 9, the finger rest lever 18 is moved from the state shown by the solid line in FIG. If it is pulled downward (position indicated by the chain double-dashed line), the head 7 is pushed down with a similar small force. Can be lowered.
