By fitting into the groove 31g of 1a, the displacement of the side wall is prevented. When the loading of the irregular-shaped container 40 is completed, the posture of the container holder 30 is free, and the container holder 30 is normally kept upright.

To pour out the liquid contained in the irregular-shaped container 40, first remove the cap 55, insert a finger into the vertically long hole 31k of the holder body 31, hold it, and turn it sideways to remove the spout body 51. I will lower it. When the holder main body 31 is sufficiently inclined, the liquid pushes the ball 52 against the pressing force of the conical spring 53 by weight, moves to the position shown by the two-dot chain line in FIG. 6, and flows out around the ball 52. The irregular-shaped container 40 shrinks by the volume of the liquid that has flowed out, so that air does not alternately flow in during pouring. Since the spout body 51 is inclined 45 ° from the beginning, the rotation of the holder body 31 required for pouring is small, and the pouring operation is easily performed.

When it is desired to increase the outflow speed, or when the outflow speed is reduced due to a low remaining amount of liquid,
A finger is inserted through the vertically long hole 31k of the left main body 31a and the push plate 32 is pressed. The push plate 32 pushes the body of the irregular-shaped container 40, whose upper and lower ends are fastened by a flange 40d and a hook 31m, from the side, and squeezes inward to pour out the liquid strongly. When the extraction is stopped while the liquid remains in the irregular-shaped container 40, the holder main body 31 is returned to the vertical posture as soon as possible. The liquid in the irregular-shaped container 40 accumulates in the lower part and widens the cross-sectional area of the lower part. However, the air is not sucked because the conical spring 53 presses the ball 52 to contact the valve seat to close the liquid passage 53. Next, the cap 55 is screwed onto the spouting tube 51c and sealed.

Next, a second embodiment of the present invention will be described. In the first embodiment, the spout 40a of the irregular-shaped container 40 shown in FIG. 2 is disposed on the upper inclined surface (shoulder). In the present embodiment, the two-dot chain line shown in FIG. It is formed at the position, that is, at the top. On the other hand, in the above embodiment, the square hole 31h of the container holder 30 is formed on the inclined surface (shoulder), but in the present embodiment, as shown by the two-dot chain line in FIG. A square hole 31h is formed in the top of the container holder 30 corresponding to the outlet 40a. At this time, the square hole 31 is formed in the overlapping portion of the left and right main bodies 31a, 31b. Even with such a configuration, the same effect as in the first embodiment can be obtained.

[0020]

According to the holder for an irregular-shaped container having a spout according to the present invention, when the holder is tilted and the liquid of the contents is poured out and returned to the vertical position again, the holder remains in the irregular-shaped container. Even if liquid remains, the check valve closes the liquid passage by the spring,
Since outside air is not sucked into the irregular-shaped container, contamination and oxidation by microorganisms and oxygen contained in the air are prevented, and deterioration of the quality of the contents can be prevented. In addition, it is possible to stably stand an indefinitely shaped irregular container, and when pouring the liquid in the container, since the spout is provided at an inclined or sunk portion, the pouring operation is easy. .
The holder can be divided through a thin hinge part like a clam, and the spout with a check valve is a cap type, so that both can be easily detached, disassembled and cleaned.
