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 to the upper end of the tube body 23a.

This pouring auxiliary pipe 23 is arranged so that the seal pipe 23b is brought into contact with the periphery of the upper end opening 19 of the gutter groove 15, while the pipe main body 2
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.

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.

Further, the front wall 25 of the pipe cover is formed into a substantially L-shape so as to have the same shape as the front opening 41 of the gutter groove 15, and an upward protrusion 26 is provided at the upper end of the front wall 25. An inwardly facing claw piece 28 is formed at the lower end, and protrusions 31, 31 are formed on the inner surface of the claw piece 28, and are press-fitted to the inner surfaces of the side walls 30, 30 of the gutter groove 15.

After the front wall 25 of this pipe cover engages its protrusion 26 into the hole 27 formed at the outer edge of the upper end opening 19 of the gutter groove 15, the protrusion 31,
31 into the inner surfaces of the side walls 30, 30 of the gutter groove 15, and by engaging the claw pieces 28 with the projections 29 on the side of the gutter groove 15, the front opening 41 of the gutter groove 15 is opened. 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
A splash phenomenon no longer occurs at the lower end opening 33 of the auxiliary pouring pipe 23, which serves as a substantial liquid inlet. In addition, since the spout 12 of the liquid spouting pipe 11 and the auxiliary spouting pipe 23 are communicated with each other with a gap, even if an infant or the like accidentally sucks water from the lower end opening 33 of the auxiliary spouting pipe 23, The content liquid W is not poured out because air flows in from the above-mentioned space.
Note that gas and liquid may be ejected in a mixed state from the spout 12 of the liquid spout pipe 11;
Since the and the auxiliary pouring pipe 23 are communicated in the pipe cover 14, splashing of liquid to the outside is prevented, and the rear wall 40 of the pipe cover 14 prevents liquid from splashing inward of the main case 1. is also prevented.

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
Since the pipe cover 14 to cover the pipe cover 14 has a front wall 25, both side walls 30, 30, and a rear wall 40 covering the front, both sides, and rear of the auxiliary extraction pipe 23, respectively, the pipe cover 14 is Improved rigidity,
The auxiliary spout pipe 23 can be reliably protected, and even when the liquid spout pipe 11 and the auxiliary spout pipe 23 are communicated within the pipe cover 14 by the rear wall 40 of the pipe cover, the content liquid W can be protected. This has the effect of reliably preventing water droplets ejected from the liquid spouting pipe 11 from scattering inward of the main body case 1 when the liquid is running low, and also prevents the spout 12 of the liquid spouting pipe 11 from Since the auxiliary spouting pipe 23 is connected to the atmosphere through a gap, even if a child or the like accidentally puts his/her mouth through the opening at the bottom of the auxiliary spouting pipe 23 and suctions, the boiling water in the middle container 2 will be removed. It is safe and will not be poured out. This has a practical effect.
