BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a liquid container according to an embodiment of the present invention; The spout structure shown in FIGS. 1 and 2 shows the first embodiment attached to a spout 21 of a liquid container 20 composed of a PET bottle. The spout structure includes a fitting portion 1 fitted into the spout portion 20 for mounting the lid portion 10, a cover portion 2 provided in the fitting portion 1, and a vent formed in the cover portion 2. 3 and cover part 2
And a partition piece 5 connected to the partition.

That is, the spout 21 of the container 20 has a cylindrical shape, and has an annular projection as one of the hooking means of the hooking means for attaching the fitting portion 1 at an intermediate position in the height direction on the outer peripheral surface. 2
2 are formed. Reference numeral 23 in the drawing denotes an annular protrusion provided at the base of the spout 21. The fitting portion 1 made of plastic is detachably attached to the spout 20. Here, the fitting portion 1 is formed with a vertical annular concave portion 6 that fits the spout portion 21 from the upper end and presses against the spout portion 21 as the other hooking component for attaching to the spout portion 21. In the present invention, the attachment of the spout 21 and the fitting portion 1 is not limited to the above-described embodiment. For example, as shown in FIG. Is formed, and the annular projection 23 is fitted outside,
Various known mounting structures can be used.

Further, in this embodiment, the fitting portion 1 is exemplified as being configured to be detachable from the spout portion 21 of the container. However, the fitting portion 1 may be fixed so that it cannot be removed after it is attached. Further, since the fitting portion 1 has a structure in which the lid portion 10 is detachably attached, for example, a male screw 11 is formed on the outer periphery of the fitting portion 1 as shown in FIG. A corresponding female screw 12 is formed on the inner peripheral surface, and the cover 10 is screwed.
Can be attached and detached. Alternatively, as shown in FIG. 3, one locking structure 11 is provided at the upper edge of the fitting portion 1 for engaging and recessing engagement, and the other locking structure 12 is provided at the lower edge of the lid 10 to be detachable. And the like can be appropriately selected and used.

Next, a cover 2 is attached to the fitting portion 1, and a part of the upper end opening surface of the spout 20 is covered. That is, the upper end opening surface of the spout 20 is circular,
The cover portion 2 covers a part of the cover portion in a substantially semicircular shape, and the opening portion that is not closed becomes a substantial spout 8. Here, the shape of the cover 2 is not particularly limited as long as it covers the opening surface with, for example, a fan shape or any other shape, and the openings not covered by the cover 2 are as shown in FIG. The opening portion of the spout portion 20 is narrowed to have a fan shape, a rhombus shape, a circular shape, an oval shape, or any other shape, thereby forming a substantial spout 8.

Next, a ventilation hole 3 made of a through hole is formed in the cover portion 2. It is preferable that the ventilation hole 3 is arranged on the cover 2 at a position farthest from a partition 5 described later. The ventilation hole 3 is for supplying air into the container in order to eliminate a liquid pressure difference in the container. The ventilation hole 3 may be provided with a ventilation protection piece 4 that covers the ventilation hole 3 to allow ventilation and prevent liquid from flowing out. As the ventilation protection piece 4, for example, when forming the ventilation hole 3, a part of the cover 2 is cut and raised to form the ventilation hole 3, and the cut and raised piece can be used.

Here, the cover 2 shown in FIGS.
In the illustrated example, the partition 5 extends perpendicularly to the linear side 2a serving as an edge thereof and extends toward the inside of the container, and the partition 5 that partitions the inside of the spout 20 in the axial direction is integrally connected. Extends over substantially the entire length of the spout 20 and partitions the spout 21 along its axis. The left and right ends of the partition piece 5 may be connected to the inner wall of the spout 20 or may be separated and inserted with a slight gap between the partition wall 5 and the inner wall.

With the above structure, when the liquid container 10 is tilted and the liquid is discharged, the liquid passing through the spout 20 hits the partition plate 5 to disturb the pulsation and the air from the vent hole 3. The liquid pressure difference is eliminated by the air (pressure) supplied into the container, and the liquid splash at the time of discharge can be suppressed. In addition, the liquid which is going to flow out of the ventilation hole 3 is a ventilation protection piece 4.
Is disturbed by Further, since the spout structure 1 is formed in the fitting portion 1 attached to the spout portion 20, the lid portion 10 can be attached to the fitting portion 1 to completely cover the spout portion 20.

Next, in the above-described embodiment, the case where the opening 8 provided in the cover portion 2 has a fixed size is illustrated, but the opening area may be adjusted so as to be reduced. For example, as shown in FIG. 6, a substantially fan-shaped adjustment piece 9 is pivotally supported P1 on the cover part 2, and a guide groove G for guiding the adjustment piece is provided on the inner peripheral surface of the fitting part 1 if necessary. The edge of the adjustment piece 9 is slidably fitted. Then, the adjustment piece 9 can be turned to a desired angle and adjusted in a direction to reduce the opening area of the cover 2. 9a is a grip for sliding the adjusting piece 9a.

When the adjusting piece 9 is not used, the cover 2 is
By turning so as to completely cover the opening, the liquid can be prevented from flowing out from the opening. In the above embodiment,
The adjustment piece 9 is superimposed on the cover 2 and the opening 8 is closed by pivotally displacing the adjustment piece 9. For example, the cover pieces 2 a and 2 b divided into two as shown in FIG. The pivot P1 may be pivoted, and one or both may be rotated in the turning direction so that the opening 8 can be widened or narrowed and adjusted.
At this time, the cover pieces 2a and 2b are set to have a shape having no portion overlapping with the ventilation hole 4 at the time of displacement so that the ventilation hole 4 is not blocked by the displacement.

Next, in the above-described embodiment, the case where the partition piece 5 is formed integrally with the cover portion 2 is shown, but the partition piece 5 may be configured so that a selected one can be attached.
For example, as shown in FIG.
On the other hand, a projection 5a having a hook-like cross section which can be engaged with the dovetail groove 2c is formed on the upper end of the partition piece 5 in advance. Then, by bending the hook-shaped protrusion 5a into the dovetail groove 2c while being bent by the elastic force of the material, the partition piece 5 can be attached to the cover 2. Thereby, it is possible to select a partition piece 5 having a length, a shape, or another structure according to the use, and attach an optimal one to the cover portion 5.

Further, the partition piece 5 may be fixed to the inner peripheral surface of the fitting portion 1 without being provided continuously with the cover portion 2. For example, the upper end of the partition 5 is disposed in contact with the back surface of the cover portion 2, and the upper portions of both side edges thereof are integrally fixed to the inner peripheral surface of the fitting portion, or from the dovetail groove and the hook portion as described above. Alternatively, a structure such as attachment using a hooking means or the like may be used. The partition piece 5 is not limited to a flat plate, and may have any cross-sectional shape as long as it can prevent liquid splashing, such as an arc-shaped cross section or a V-shaped cross section.

Next, if the cover part 2 is formed integrally with the fitting part 1 or is integrally formed by fixing, the cover part 2 is formed separately and together with the spout part 21 of the container.
It may be attached to. For example, as shown in FIG. 9, an annular step portion that expands downward is formed on the inner peripheral surface of the fitting portion 1 so that the cover portion 2 can be inserted from the inside. And at the time of attachment, the spout 2 of the container
The cover portion 2 can be attached by fitting the fitting portion 1 with the cover portion placed on the cover portion 1 and pressing the cover portion 2 between the fitting portion 1 and the upper end of the spout portion 21. In addition, it goes without saying that an annular concave groove may be formed on the inner peripheral surface of the fitting portion 1 and the cover portion 2 may be fitted. Also in this case, the cover portion 2 having the optimal opening or partition piece for the fitting portion 1 depending on the application.
Can be attached.

In the above embodiment, a PET bottle has been described as an example of a liquid container.
The structure and use are not particularly limited, and any container may be used as long as it has a spout and stores a liquid, and the type of the liquid is not limited. The opening (spout) formed between the inner peripheral surface of the fitting portion and the cover is sealed with an easy-open lid, and may be opened when used. In addition, if the upper opening of the fitting portion is sealed with a seal or the like when not in use, leakage of the liquid in the container can be prevented, and known configurations can be appropriately combined.

[0018]

According to the spout structure of the liquid container of the present invention, the partition piece and the ventilation hole can prevent the liquid to be discharged from splashing and can discharge the liquid smoothly. In addition, since the lid can be attached to the fitting portion, it can be attached to the spout of the liquid container in advance. Alternatively, in the case of a liquid container using a stopper, such as sake, after opening, a fitting portion can be attached to prevent liquid splashing as described above.
