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

In the case shown in FIG. 2, the retainer lid 11 is locked and the liquid spouting tube 10 is in the retracted state.

That is, the locking rod tip 18a of the operating member 15 engages with the horizontal portion 16a of the engagement groove 16 formed in the presser cover opening wall 17 to lock the presser cover 11 so that it cannot move up and down, while the operation The lower end portion 15b of the member engages with the claw piece 22 of the liquid spouting tube 10 to bring the liquid spouting tube 10 into a retracted state.

In this system, the presser cover 11 cannot be pressed, and there is no possibility of accidentally pouring out the liquid content while the liquid pouring tube 10 is in the retracted state.

When attempting to pour out the contents using this liquid container, when the operating member 15 is rotated in the direction of arrow B along the guide groove 21 using the knob 27, the locking rod tip 18a engages. It will engage with the vertical part 16b of the groove 16, and the presser cover 11 will be unlocked to be able to move up and down, and at the same time, the lower end part 15b of the operating member will be disengaged from the claw piece 22, and the liquid spouting pipe 10 will be released. is pushed out in the direction of arrow A by the biasing force of the spring 19, and is projected out of the outer circumferential surface of the main body 1 as indicated by reference numeral 10' in FIG.

Under this system, when the presser cover 11 is pressed, the air pump 6 is driven and pressurized air can be pumped into the liquid container 2, and the pressurized air pumps the liquid content into the liquid pumping tube 9.
And it can be poured out to the outside through the liquid pouring pipe 10.

After that, in order to retire the liquid spouting tube 10, push in the liquid spouting tube 10 with your finger and at the same time move the operating member 15 with the arrow B.
The lower end portion 15b of the operating member and the claw piece 22 may be engaged with each other by rotating in the opposite direction.

In this first embodiment, the locking rod 18 for locking the presser cover is integrally formed on the operating member 15, but the operating member 15
Of course, other locking means may be used for the top lid 11, while the locking means may be used exclusively as a stopper for the outer bottle tube 10.

In the second embodiment of the present invention shown in FIGS. 3 and 4, the operating member 15 is disposed inside the upper lid 4, and the rotation operation of the operating member 15 causes the presser lid 11 to rotate. It is now done by

That is, the upper end 15a of the operating member 15 is bent toward the presser cover 11, and by engaging the upper end 15a with a vertical groove 39 formed in the peripheral wall 17 of the presser cover 11, the operating member 15 and the presser are connected. The lid 11 is configured to rotate together.

The reference numeral 40 is a projection for preventing removal.

The structure other than the above is the same as that of the first embodiment, so the explanation thereof will be omitted.

In this case as well, as in the first embodiment, when the presser cover 11 is rotated in the direction of arrow B, the lower end portion 15b of the operating member and the claw piece 22
The liquid spouting tube 10 can be made to protrude by the biasing force of the spring 19.

In the third embodiment of the present invention shown in FIG.
A stopper 41 having a diameter is integrally formed.

By locking the pawl 42 in a force-fitted manner at an appropriate location on the inner surface of the upper lid 4, the operating member 15 is connected to the liquid spouting tube 1.
It is fixed to maintain a retired state of 0.

In this case, when the operating member 15 is pushed down slightly to release the locking by the claw 42, the liquid spouting tube 10 is moved by the spring 19 while the claw piece 22 and the lower end portion 15b of the operating member remain engaged. It is made to protrude by a biasing force.

In each of the above embodiments, the upper lid is opened and closed, but it goes without saying that the present invention can also be applied to a pump-type liquid container with a removable upper lid.

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

That is, according to the present invention, the liquid spouting pipe 10 that can move forward and backward and the operating member 15 that can be rotated or slid from the outside are disposed on the upper lid 4 side, and the lower ends of the liquid spouting pipe 10 and the operating member 15 are arranged. Since the retracted state of the liquid spouting tube 10 is maintained by engaging the portion 15b, there is no need to align the engaging portion when opening/closing or attaching/detaching the top cover 4, and the operating member 15 and the liquid This has the effect that the linking portion with the spouting pipe 10 can be simplified.

Further, since the recess 38 formed on the side surface of the main body 1 for allowing the liquid spouting tube 10 to enter and exit is closed by the tip opening 25 of the liquid spouting tube 10, a separate lid for closing the recess is provided. It is no longer necessary and the structure can be simplified.

Further, when the liquid spouting tube 10 is in the retracted state, the distal end spout 25 and the side surface of the main body 1 are made to be the same, so unnecessary protrusions are eliminated and compactness can be achieved.

Furthermore, the liquid spouting tube 10, which is biased in the protruding direction by the spring 19, is brought into a retracted state by engaging with the lower end portion 15b of the operating member, and by rotating or sliding the operating member 15, the above-mentioned engagement is made. Since the liquid spouting tube 10 is brought into the protruding state by releasing the joint, there is an effect that the liquid spouting tube 10 can be easily made to protrude simply by rotating or sliding the operating member 15.
