The pump liquid injection pot of the first embodiment shown in FIGS. 1 to 3 has a medium bottle 5, which is a vacuum double bottle, housed as a liquid container in an outer case 4, and a dish-shaped pot in the upper part of the outer case 4. a pot body 1 on which a lower mouth member 6 is mounted and fixed; a lid body 2 containing a bellows-type air pump 9 as a pump device therein; and a bottle inner tube 14 extending downward in a frame portion 13. A liquid injection system having a water conduit unit 8 to which a laterally extending bottle outer tube 15 is attached, and a telescopic double pipe 20 for guiding the liquid discharged from the distal end outlet 8a of the water conduit unit 8 downward. It has an auxiliary tool 10.

The lid body 2 is pivotally attached to the upper rear side of the pot body 1 by a hinge 3.

A plug insertion hole 7 serving as a water supply port is formed approximately in the center of the lower mouth member 6.

A frame portion 13 of a water conduit unit 8 is removably fitted into this plug insertion hole 7.

A protrusion 11 that protrudes forward from the front surface 4a of the outer case 4 is formed in the front part of the lower mouth member 6, and the protrusion 11 is provided with a distal end outlet 8a of the water conduit unit 8 so as to face downward. A hole 12 is formed.

The bottle inner pipe 14 and the bottle outer pipe 15 of the water conduit unit 8 are connected to the frame part 1.
They are communicated with each other via water passages 16 within the 3.

Further, a ventilation passage 17 is formed in the frame portion 13 to penetrate in the vertical direction, and the air pump 9 and the inside of the medium bottle 5 are communicated through the ventilation passage 17 when the lid is closed.

When the water conduit unit 8 is installed, its distal end outlet (the distal end of the bottle outer tube 15) 8a faces downward through the hole 12 of the lower mouth protrusion 11.

Below the lower protrusion 11, there is a telescopic double tube 20 formed by telescopically connecting a straight inner pipe 21 and an outer pipe 22 each having an appropriate length, and an outer side of the telescopic double pipe 20. Liquid injection aid 10 consisting of a cover member 30 with a bottom for covering
is installed.

The cover member 30 is fixed to the front surface 4a of the outer case with screws.

The inner pipe 21 of the telescopic double tube 20 is attached facing forward of the lower needle with the opening of its upper end 21 a communicating with the hole 12 of the lower protrusion 11 .

The inner pipe 21 also includes a support piece 33 in which a flange 21C formed on the upper end 21a of the inner pipe 21 projects inwardly from the back surface of the front wall 31 of the cover member 30, and a lower surface of the lower protrusion 11. It is fixed by sandwiching it between the two.

The opening edge of the hole 12 of the lower protrusion 11 is folded back so as to protrude slightly downward, and the opening of the upper end 21a of the inner pipe is fitted onto the outside of the folded portion.

The outer pipe 22 of the telescopic double pipe 20 has an upper half 24 thicker than the outer diameter of the inner pipe 21 and a lower half 25 formed of a pipe with a step 26 having approximately the same diameter as the inner pipe 21. The outer pipe 22 is configured to be able to slide in the length direction (vertical direction) with respect to the inner pipe 21 at an upper half 24 portion of the outer pipe.

A front wall 3 of a cover member 30 is provided on the outer surface of the upper half portion 24 of the outer pipe.
A knob portion 27 that penetrates through 1 and projects outward is integrally formed.

The front wall 31 of the cover member 30 is inclined substantially forward of the lower needle with the inclination of the telescoping double pipe 20, and the front wall 31 has a structure for guiding the outer pipe knob 27 as shown in FIG. A guide groove 35 is formed.

This guide groove 35 has a vertical groove 36 having an appropriate length in the vertical direction.
There are two horizontal short horizontal grooves 37.3 at two locations, one slightly below the upper end 36a of the vertical groove 36 and the lower end of the vertical groove.
8 in series.

The knob portion 27 is guided by the vertical groove 36 and moves up and down, and can engage into the upper and lower lateral grooves 37 and 38, respectively.

The outer pipe 22 can slide vertically relative to the inner pipe 21 within the range in which the knob portion 27 can move up and down within the vertical groove 36 of the guide groove 35.
2 is designed such that when the knob portion 27 engages in the upper and lower lateral grooves 37 and 38, vertical sliding is prevented at that position.

Note that even when the outer pipe 22 is fully extended relative to the inner pipe 21 (Fig. 1), the upper half 24 of the outer pipe and the inner pipe 2
1 is such that they are polymerized by an appropriate length in the vertical direction.

The lower end 25 a of the lower half of the outer pipe 25 is a cover member 30
It is made to protrude downward from a hole 34 formed in the bottom wall 31 of.

On the inner surface of the upper half portion 24 of the outer pipe, there are a plurality of vertical protrusions 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 28, 4, etc.
... are formed at equal intervals in the circumferential direction.

This vertical protrusion 28 serves as a guide to prevent the outer pipe 22 from sliding laterally with respect to the inner pipe 21.

Further, a plate-shaped water stop valve 23 having a diameter slightly larger than the lower end opening 21 b of the inner pipe 21 is provided at a lower portion within the upper half portion 24 of the outer pipe (slightly above the stepped portion 26 ).

This water stop valve 23 is integrally fixed to the inner end surfaces of the vertical protrusions 28, 28, . . . .

Also, this water stop valve 23 is designed so that when the outer pipe 22 is contracted to the uppermost position relative to the inner pipe 21 (FIG. 2), the outer pipe knob 27 is in contact with the vertical groove 36 of the front wall 31 of the cover member. It is positioned so that when it comes into contact with the upper end portion 36a, it can come into contact with the lower end opening 21b of the inner pipe and close the lower end opening 21b.

A spring 29 is interposed between the step portion 26 of the outer pipe 22 and the bottom wall 31 of the cover member, and the spring 29 acts to bias the outer pipe 22 upward. When located in the vertical groove 36, the outer pipe 22 is pushed upward by the spring 29, and the water stop valve 23 automatically closes the lower end opening 21b of the inner pipe.

In addition, when injecting liquid, if the knob part 27 is engaged with the upper lateral groove 37 or the lower lateral groove 38, the water stop valve 23 is separated from the lower end opening 21b of the inner pipe, and the outer pipe 22 is connected to the inner pipe 21.
The liquid can be injected either in an upwardly contracted state or in a downwardly expanded or contracted state.

The air pump 9 housed within the lid 2 is pressed and driven by a pump operation plate 19 disposed on the top of the pump top plate.

In the pump injection type pot of the first embodiment, when the pump operation plate 10 is pressed, processing air from the air pump 9 is blown into the medium bottle 5 through the air passage 17 inside the stopper, and the pressurized air is used to fill the medium bottle. The liquid W in the bottle 5 can be poured out to the outside through the introduction pipe unit 8 and the telescopic double pipe 20.

In addition, when pouring the liquid W in the medium bottle 5 into the relatively short liquid receiving container A, as shown in FIGS. is inserted into the lower lateral groove 38 of the guide groove 35 and pulled out downward, and the liquid receiving liquid is placed on the floor directly below the lower end spout 25a (lower end opening of the outer pipe 22) of the telescopic double pipe 20. When pouring liquid into a relatively tall liquid receiving container A, place the knob 27 in the upper lateral groove 37 of the guide groove 35.
This may be done while the outer pipe 22 of the telescopic double pipe 20 is pushed upward.

If the height of the lower end spout 25a is adjusted by expanding and contracting the telescopic double tube 20 according to the height of the liquid receiving container A, it is possible to keep the liquid receiving container A on the floor. When pouring liquid, there is no splashing of the liquid and the floor surface is not wet.

When this pot is not in use, the outer pipe 22 of the telescopic double pipe 20 can be contracted to the uppermost position and the lower end opening 21b of the inner pipe 21 can be closed off with the water stop valve 23, as shown in FIG. In this case, even if the pot is accidentally overturned, when the liquid W in the medium bottle 5 flows out through the water conduit unit 8, water will not leak to the outside from the lower end spout 25a of the telescopic double pipe 20. Further, even if a child accidentally presses the pump operation plate 19, the liquid W will not be discharged from the lower end spout 25a of the telescopic double pipe 20.

In addition, since the outer pipe 22 is urged upward by the spring 29, when the outer pipe 22 is contracted to the uppermost position, the water stop valve 23 is in pressure contact with the rim of the lower end opening 21b of the inner pipe. Valve closing action is ensured.

In the pump liquid injection pot of the second embodiment shown in FIG. 4, a spring plate 40 extending upward is integrally formed at the front upper end of the outer pipe 22 of the telescopic double pipe 20, and the tip thereof serves as an engaging part. A protrusion 41 facing outward is formed, and the back side of the front wall 31 of the cover member has several recesses 42 and 42 that engage with the protrusion 41.
The outer pipe 22 can be expanded and contracted in stages by engaging the protrusion 41 with a suitable recess 42.

Note that when the protrusion 41 is engaged with the recess 42 at the top, the water stop valve 23 in the outer pipe 22 closes the lower end opening 21b of the inner pipe 21.

In addition, in FIG. 4, the reference numeral 43 indicates the lower end opening 21 of the inner pipe.
It is an annular gasket provided in b.

In the pump liquid injection pot of the third embodiment shown in FIGS. 5 and 6, the inner pipe 21 of the telescopic double pipe 20 has a female thread carved into the inner surface of the opening of the upper end 21a of the inner pipe. The screw tube 44 inserted from above the hole 12 of the lower protrusion 11 is screwed onto the female screw, and the rim of the hole 12 is sandwiched between the upper end 21a of the inner pipe and the screw tube 44. It is fixed to the lower surface of the lower mouth protrusion 11 in such a way that it can be found.

In addition, the lower end opening 21b of the inner pipe 21 is provided with a disc 46 with a narrow annular water inlet 45 formed inside the opening edge.
are integrally fixed.

The lower surface of this disc 46 is attached so as to be flush with the lower end of the inner pipe 21.

The outer pipe 22 has an inner diameter slightly larger than the outer diameter of the inner pipe 21, and the outer pipe 22 is frictionally engaged with a rubber O-ring 47 attached to the outer surface of the inner pipe 21, so that the outer pipe 22 can be moved to any expansion/contraction position. I'm trying to make it fixed.

Further, the lower end of the outer pipe 22 is connected to the lower end opening 21 of the inner pipe.
A narrow opening 48 having a slightly smaller diameter than the outer diameter of the disc 46 formed in b.
A stepped portion 49 is formed between the narrow portion 48 and the outer pipe body.

This stepped portion 49 closes the water stop valve 23 for closing the water passage port 45 at the lower end of the inner pipe 21 when the outer pipe 22 is contracted to the uppermost position.

Further, a locking protrusion 50 is formed on the outer surface of the upper end of the outer pipe 22 and protrudes forward, while the protrusion 50 is elastically held on the back surface of the front wall 31 of the cover member and rotates vertically. Two vertical guide walls 51 are formed for guiding.

A swivel 52 is formed at the lower part of the vibration waveguide wall 51 and projects inward to restrict the range of downward movement of the protrusion 50 of the outer pipe 22.

The upper part of the inner pipe 21 has a larger diameter than the lower part, and when the upper end of the outer pipe 22 comes into contact with the outer surface of the larger diameter part, the stepped part 49 (water stop valve 23) at the lower end of the outer pipe
becomes.

) closes the lower end opening 21b of the inner pipe.

In the pump liquid injection pot of the fourth embodiment shown in FIGS. 7 and 8, a protrusion 53 is formed on the outer surface of the middle part of the outer pipe 22, and a hole 34 in the bottom wall 32 of the cover member is provided with the outer pipe. A cylindrical body 55 formed with a spiral groove 54 that engages with the protrusion 53
By attaching the outer pipe 22 rotatably and engaging the protrusion 53 of the outer pipe 22 with the narrow groove 54 of the cylindrical body 55, the outer pipe 22
is supported by the cover member bottom wall 32.

In this case, the protrusion 53 of the outer pipe 22 that pinches and rotates the lower end (knob) 56 of the cylindrical body 55 is guided by the spiral narrow groove 54 and moves up and down, so that the outer pipe 22 is connected to the inner pipe 21. It is made to be able to expand and contract.

Further, a cover plate 58 is integrally formed on the lower end opening 21b of the inner pipe 21, and has two fan-shaped water passage ports 57 and 57 formed at opposite positions from the center thereof, each at an angle slightly smaller than 90°. On the other hand, in the lower part of the inside of the outer pipe 22, there are similar fan-shaped water holes 59, 59 at positions shifted by 90 degrees in the circumferential direction from the fan-shaped water holes 57, 57 on the inner pipe 21 side.
A valve plate 60 is integrally formed.

When the outer pipe 22 is contracted to the uppermost position, the valve plate 60 of the outer pipe 22 is connected to the fan-shaped water inlet 57 at the lower end of the inner pipe 21.
