is always urged upward by a bellows extension spring 23, and its upward movement is restricted by a hook 22a. Reference numeral 24 is a gasket that seals the suction port 20 when the suction valve 22 is closed.

The discharge port 21 can communicate with the air passage 7 of the inner stopper 6 when the lid is closed.

The air pump 19 has a guide cylinder 25 that is vertically disposed from the center of the upper surface 2a of the lid 2 (above the center line g of the main body).
It is manually pressed and driven by a crown-shaped pressing member 26 that is located inside and slides up and down.

Between the pressing member 26 and the water stop valve 15,
An interlocking mechanism 27 is provided to transmit the vertical movement of the pressing member 26 to the water stop valve 15.

The interlocking mechanism 27 has a flange 28a that is located directly above the seal packing 17 on the top of the water stop valve 15 on the center line g of the main body, passes through the suction valve 22 and the air pump bottom plate 19b, and is formed at the upper end of the suction valve 2.
2. A pressing rod 28 that is disposed to be locked on the upper surface of the suction valve 22, a spring 29 that urges the pressing rod 28 downward, and a cylindrical body 30 that is fixed to the upper part of the suction valve 22 to support the upper end of the spring 29. It is composed of: The spring 29 is made slightly weaker than the spring 23 for pump extension. Note that the lower end of the pressing rod 28 is normally positioned slightly above the upper surface of the seal packing 17, and the diameter of the lower end of the pressing rod 28 is larger than that of the seal packing 17.
It is determined to be able to close the air supply port 18 of.

Further, a pair of engagement protrusions 31 are integrally provided on the upper side peripheral surface of the pressing member 26 at symmetrical positions.

Further, on the inner circumferential surface of the guide tube 25, guide grooves 32, 3 are provided in which the engaging protrusions 31, 31 are to be engaged.
2 is formed.

The guide groove 32 has two vertical grooves 32a and 32b whose lower ends are open, as shown in FIGS. 2 and 3.
The upper locking portions 33 and 34 are located above the vertical grooves 32a and 32b and are located below the vertical grooves 32a and 32b.

The upper and lower locking portions 33 and 34 engage with the engagement protrusions 31 and 31 of the pressing member 26, and act to restrict upward movement of the pressing member 26.

When the engagement protrusion 31 engages with the upper locking part 33, the pressing member 26 moves upward to the position where the water stop valve 15 closes, while when the engagement protrusion 31 engages with the lower locking part 34, The pressing member 26 is configured to move upward only to a position where the water stop valve 15 is held in an open state.

By rotating the pressing member 26 in the direction of arrow A or B, the engaging protrusion 31 is selectively engaged with the upper or lower locking portion 33 or 34.

Note that the side surface of the vertical groove 32b on the vertical groove 32a side is slightly inclined.

Next, the operation of the illustrated siphon type liquid container will be explained.

When the engaging protrusion 31 of the pressing member 26 is engaged with one of the vertical grooves 32a of the guide groove 32 (as shown by the solid line in FIG. 3), the pressing member 26 is moved upwardly by the upper locking portion 33. When the pressure member 26 is at the top dead center, the water stop valve 15 is in an open state.
Therefore, the pouring operation is an air pressure feeding type (so-called air pot type) in which the pressing member 26 is repeatedly pressed.

On the other hand, when rotating the pressing member 26 in the direction of arrow B (see FIG. 2) to engage the engaging protrusion 31 with the other longitudinal groove 32b of the guide groove 32 (as shown by the dotted line in FIG. 3), the pressing member 26 is The upward movement of the member 26 is restricted by the lower locking portion 34, and when the pressing member 26 is at the top dead center, the water stop valve 15 is maintained in an open state. Therefore, even if the pressing force on the pressing member 26 is released, continuous dispensing is possible due to the siphon effect. Thereafter, when the pressing member 26 is rotated in the direction of arrow A (see FIG. 2), the engaging protrusion 31 moves toward the vertical groove 32a side and is engaged with the upper locking part 33, so that the water stop valve 15 is closed and dispensing is stopped.

Next, the effects of the siphon-type liquid container of the present invention will be described.

According to the present invention, in the siphon-type liquid container, the water stop valve 15 is disposed in the liquid passage 8 of the inner stopper 6 so as to be closed when moving upward and open when moving downward, and the air pump 19 is connected to the water stop valve 15. The pressing member 26 for pressing and driving can be interlocked with the interlocking mechanism 27, and the engaging protrusion 31 formed on the pressing member 26 is attached to the lid body 2 when the water stop valve 15 is in the closed position. An upper locking portion 33 that is locked to restrict upward movement of the pressing member 26 and the engaging protrusion 31 hold the pressing member 2 in the open holding position of the water stop valve 15.
The lower locking part 3 is locked so as to restrict the upward movement of 6.
4, the engagement protrusion 31 of the pressing member 26
By selectively locking with the upper locking part 33 or the lower locking part 34, continuous dispensing by siphon effect and pneumatic feeding type (so-called air pot type) dispensing operation can be appropriately selected. This has the practical effect of improving usability.
