Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pouring spout which is inserted and mounted in a bottle mouth.

“Prior Art” Several pouring openings for smooth pouring of a liquid in a bottle have been conventionally proposed. As a typical example, it is formed of a solid body with a V-shape, one half is the mounting side, the other half is the pouring side, and the outside air intake hole is formed on the inner surface on the side opposite to the spout There is something I did.

"Problems to be solved by the device" Since this kind of pouring mouth is used by inserting it into the bottle mouth liquid-tightly, there is the inconvenience that it cannot be used for bottles with different caliber,
For this reason, it is necessary to prepare the ones corresponding to various bottle diameters, which is uneconomical.

The present invention is to obtain a convenient pouring spout that can be cut by a part of a cylinder wall to be expanded and reduced in diameter so that it can be used for bottles having different diameters.

[Means for Solving the Problem] The pouring spout of the present invention has a tapered cut end and an elastically deformable short cylindrical body 2 having a tip projecting side as a spout 1 and an anti-pouring port side cylinder wall. Is recessed inward in a trough shape and extends downward to the base end side, and is cut at one bent edge 4 of the recessed portion 3 or a cylindrical wall portion in the vicinity thereof.

[Operation] As shown in Fig. 1 and Fig. 2 a and b, the above-mentioned pouring port is in the expanded state in which the cutting portion a is greatly opened in the normal state, and from this expanding state until the cutting portion a is closed. The diameter can be reduced. In this case, most of the bottles used daily can be accommodated if the bottle with the largest diameter is used in the expanded state and the bottle with the smallest bottle diameter is used in the contracted state. .

FIG. 3a is a diagram when the diameter is reduced and used for the bottle 5 having a small diameter, and FIG. 3b is a diagram when used for the bottle 5 having a large diameter in the normally expanded state. At the time of this insertion mounting, the concave portion 3 forms the outside air suction hole 6. In FIG. 3b, the opening of the cutting portion is located on the side opposite to the spout 1, and there is no problem in pouring.

[Embodiment] An embodiment will be described below with reference to the drawings. The pouring spout according to the present invention has a shape in which a part of a cylinder wall is cut to be able to be expanded and reduced in diameter, and the diameter of the bottle 5 is different. It has a feature in that it can be used for.

For this reason, as shown in FIGS. 1 and 2a and 2b, the anti-pouring tube wall of the elastically deformable short tubular body 2 with the tip as a tapered cut and the tip protruding side as the spout 1 is formed. It is recessed inward in the shape of a gutter and extends downward to the base end side.
The shape is such that the collar 7 that is cut at one of the bent edges 4 on one side and is provided on the outer surface near the base end of the short tubular body 2 from which the recessed portion 3 is omitted is provided with a collar 7 that serves as a stopper when inserted into a bottle mouth and attached. It is made of resin material.

In this case, as shown in the drawing, the cutting portion (a) is formed in a diameter-expanded state in which it is wide open in the normal state, and the diameter can be reduced from this diameter-expanded state until the cutting portion (a) is closed.

With the above-mentioned configuration, the recessed portion 3 forms the outside air suction hole 6 when inserted into the mouth portion of the bottle 5 as shown in FIGS. 3A and 3B, and also the bottle 5 having a different diameter by expanding and contracting deformation. Available for

The cutting portion (i) may be on the opposite side of the spout 1 and at a position where it does not hinder the liquid pouring out. Therefore, the cutting portion (i) is not limited to the one bent edge 4 of the recessed portion 3 described above, but a cylinder in the vicinity thereof. It may be a wall. In addition, the cap of bottle 5 is not shown in the figure,
If a tall cap that completely covers the pouring spout inserted into the bottle mouth as shown by the double-dotted line 8 is used as this cap, the pouring spout can be saved without treating it separately from the bottle 5.
It is advantageous in handling.

[Advantage of the Invention] As described above, the spout of the present invention has a tapered cut end and an elastically deformable short tubular body 2 with the tip projecting side as the spout 1 The wall is recessed inward like a gutter and extends downward to the base end side, and is cut by one of the bent edges 4 of the recessed portion 3 or the cylindrical wall portion in the vicinity thereof to allow expansion and contraction deformation. Therefore, it is convenient to use for bottles 5 with different diameters, and it is economical because it can accommodate various bottles with one piece, and since it is an extremely simple shape,
It can be provided at low cost.
