A liquid pumping tube and a liquid dispensing tube connected to each other are shown.

As the medium container 2, a so-called wide-bodied bottle having a large bottle diameter and a low bottle height is used in this embodiment. Therefore, the height of the main body case 1 is also reduced.

An opening 39 is formed in the shoulder member 5 at the peripheral edge on the side opposite to the hinge pin.

Further, the spout 12 of the liquid spouting pipe 11 is located at the upper part of the main body case 1 and is opened downward, so that it is positioned facing the opening 39 when the inner stopper is tightly fitted. It's getting old.

A vertically long notch hole 1 is provided at the upper end of the main body case 1 at a position corresponding to the spout 12 of the liquid spouting pipe 11.
3 is formed.

As shown in FIG. 3, a fitting step 13a is formed on the edge of the cutout hole 13. As shown in FIG.

A pipe cover 14 having a substantially L-shaped gutter groove 15 is fitted into the cutout hole 13 by fitting flanges 16 protruding from both sides and the lower surface of the pipe cover into the stepped portion 13a. There is.

At this time, most of the vertical portion of the pipe cover 14 is made to protrude into a space S formed above the shoulder of the inner container 2 in the main case 1.

This pipe cover 14 is constructed by integrally molding both side walls 30, 30 and a rear wall 40, and has an opening 41 opening the front side of the pouring auxiliary pipe 23 on its front surface. A lid 25, which will be described in detail later, is detachably attached to the opening 41.

Note that this pipe cover 14 is attached to the rear wall 40.
is fixed to a rib 17 installed in the middle part of the notch hole 13 with a screw 18, thereby preventing it from falling off to the outside.

In the upper end opening 19 of the gutter groove 15, the spout 12 of the liquid spouting pipe 11 is exposed, while the lower end opening 20 of the gutter groove 15 is located at a horizontal distance d from the side surface of the main body case 1. 1 The vertical distance h from the bottom surface is slightly larger than the radius and height of the liquid receiving container 21 such as a pot.
By doing so, the liquid injection work can be performed more reliably and easily.

On the bottom surface of the vertical groove portion 15a in the gutter groove 15,
A pair of upward L-shaped protrusions 22, 22 are integrally protruded at appropriate locations, and the protrusions 22, 22 have a holder 2 for holding an auxiliary pouring tube 23, which will be described later.
4 is fixed (see Figure 3).

As shown in FIG. 3, the holder 24 includes a plate-shaped mounting portion 24a and a pair of arm portions 24b, 24b having an arcuate inner surface integrally protruding from the mounting portion 24a.
The projections 22, 22
The mounting portion 24a is constructed and fixed to the arm portion 24b,
The auxiliary pouring tube 23 is held between the tubes 24b and 24b.

Further, on the outer edge of the upper end opening 19 of the gutter passage 15, a locking protrusion 26 is provided to protrude from the upper end of the lid body 25.
A hole 27 into which the lid body 2 is inserted is formed on the inner surface of the groove at the lower end opening 20 of the gutter groove 15.
5. A protrusion 29 that engages a claw piece 28 protruding from the lower end.
is formed.

The auxiliary pouring pipe 23 has a substantially L-shaped pipe main body 23.
a, and a wrapper-shaped seal tube 23b made of an elastic material such as rubber and connected onto the tube body 23a.

This pouring auxiliary pipe 23 is inserted into the pipe main body 2 while the seal pipe 23b is brought into contact with the periphery of the upper end opening 19 of the gutter 15.
3a is pressed into contact with the bottom surface of the horizontal groove portion 15b of the gutter groove 15, thereby being removably disposed within the gutter groove 15. At the same time, the tube body 23a is attached to the holder 24.
It is held by the arms 24b, 24b to prevent swinging in the front, back, left and right directions. In other words, the auxiliary pouring pipe 23 is connected to the pipe cover 14 with an appropriate gap.
It is protected from direct impacts from outside. The lower end opening 33 of the signal extraction auxiliary pipe 23 is made to protrude below the pipe cover 14 by a predetermined distance. With each configuration, it becomes possible to easily confirm the position of the lower end opening 33 which becomes the actual liquid outlet.

By configuring as described above, the pouring auxiliary pipe 2
In the upper end opening 32 of 3, the spout 12 of the liquid spouting pipe 11 is exposed through an annular gap, and the liquid spouting pipe 11 and the auxiliary spouting pipe 23 are exposed to the atmosphere at this position. It is supposed to be able to communicate with the In addition, the liquid pouring pipe 11
The communication position between the auxiliary pouring pipe 23 and the shoulder member 5 is
The liquid supply port 9 of the medium container 2 is located below the top surface of the container.
It is said to be located higher up. Therefore, it is possible to make the height of the liquid pouring pipe 11 as small as possible, and as a result, the height of the portion above the shoulder member 5 can be made small, which contributes to making the liquid container more compact. . In addition, liquid pouring pipe 1
The opening position of the spout 12 of No. 1 is the liquid supply port 9 of the medium container 2.
By placing it at a higher level, we are trying to prevent the siphon phenomenon. Note that the lower end opening 33 of the auxiliary pouring pipe 23 is located slightly lower than the lower end opening 20 of the gutter groove 15.

Furthermore, the lid body 25 is formed in a substantially L-shape so as to have the same shape as the front opening 41 of the gutter groove 15, and has an upward protrusion 26 at its upper end.
However, an inwardly facing claw piece 28 is formed at the lower end thereof, and a protrusion 31 is formed on the inner surface thereof and press-fits against the inner surface of the side walls 30, 30 of the gutter groove 15.
31 is formed.

Therefore, this lid body 25 has its protrusion 26 connected to a hole 2 formed at the outer edge of the upper end opening 19 of the gutter groove 15.
7, the protrusions 31, 31 are inserted into the gutter groove 15.
The front opening 41 of the gutter groove 15 is press-fitted to the inner surfaces of the side walls 30, 30, and the claw piece 28 is engaged with the protrusion 29 on the gutter groove 15 side.
The cover is designed to be removable.

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

When pressurized air is forced into the inner container 2 from the air pump 6 through the inner stopper 8 by pressing the presser lid 7, the pressurized air causes the content W to flow through the liquid pumping tube 10 and the liquid pouring tube 10. Passing through the pipe 11, the auxiliary pouring pipe 2
3 and is poured into a liquid receiving container 21 such as a pot. In this case, the lower end opening 33 of the pouring auxiliary pipe 23, which serves as the external injection port for the liquid content W, opens at a position close to the liquid receiving container 21 placed on the floor surface on which the liquid container is placed. , the liquid can be poured while the liquid receiving container 21 is placed on the floor.

Moreover, when the content liquid W decreases, the liquid pouring pipe 11
A so-called splash phenomenon occurs in which gas and liquid are mixed and ejected from the spout 12 at the tip. Because we are approaching
The splash phenomenon no longer occurs at the lower end opening 33 of the auxiliary pouring pipe 23, which serves as a substantial liquid injection port. Note that gas and liquid may be ejected in a mixed state from the spout 12 of the liquid spout pipe 11, but the liquid spout pipe 11 and the spout auxiliary pipe 23 are connected to the pipe cover 1.
4, the liquid is prevented from scattering to the outside.

Furthermore, since the communication position between the liquid spouting pipe 11 and the auxiliary spouting pipe 23 is set above the liquid supply port 9 of the medium container 2, the siphon phenomenon during liquid pouring is avoided.

(Effect of the invention) As described above, according to the present invention, the auxiliary pouring pipe 23
An opening 4 is formed on the front surface of the pipe cover 14 to cover the
1 and the lid 25 is provided in the opening 41, so when the lid 25 is removed, the auxiliary pouring pipe 23 cannot be assembled into the pipe cover 14 or taken out from the pipe cover 14. This has the practical effect of making it easier to assemble and improving ease of assembly and after-sales performance.

In addition, since a gap is interposed between the lid body 25 and the auxiliary spouting pipe 23, even if an impact force is applied to the pipe cover 14 from the front, the auxiliary spouting pipe 23 This also has the effect that direct impact force is prevented from being applied to the auxiliary pouring tube 23, and the protection of the auxiliary pouring tube 23 becomes more reliable.

Furthermore, the liquid spouting pipe 11 and the spouting auxiliary pipe 23 are made to communicate with the atmosphere at the connection portion thereof within the pipe cover 14 and to be separable from each other, thereby eliminating the splash phenomenon. Another advantage is that the auxiliary pouring tube 23 can be easily attached and detached.

Furthermore, the lower end opening 33 of the pouring auxiliary pipe 23
is made to protrude by a predetermined distance below the pipe cover 14, which also has the effect that the position of the lower end opening 33, which serves as the actual liquid outlet, can be easily confirmed.
