Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a spout of a liquid container, and particularly to a spout suitable for highly viscous contents.

<Prior Art> Conventionally, in a liquid container or the like, a Gobel-top type paper container has been used for the purpose of reducing the manufacturing cost and weight of the container. And there are those provided with a synthetic resin spout to facilitate the pouring of liquid from these paper containers, for example, a flange portion attached to the opening of the container,
A cylindrical portion is formed on the flange portion, and a closed bottom plate that seals the cylindrical portion is continuously provided, and a thin portion for opening is formed on the closed bottom plate, and a pulling ring is formed on the upper surface of the sealed bottom plate in the thin portion. In some cases, the saw ring was pulled in series to break the thin portion to obtain a pouring hole having a desired shape.

<Problems to be solved by the present invention> In the above-mentioned pouring stopper, if the content liquid is alcohol, juice or the like having a relatively low viscosity, the liquid may be easily drained and the liquid may adhere to the outer periphery of the cylindrical portion. However, in the case of edible oil and the like, the liquid was poorly drained, and there was a problem that it was difficult to handle because it flowed out from the outer periphery of the cylindrical portion to the container body and adhered.

<Means for Solving the Problems> The present invention is to solve the above-mentioned problems, and is a pouring plug having a flange portion attached to an opening of an inclined wall of a container, and a cylindrical portion protruding from the flange portion. Are continuously provided, and a partially cutout pouring beak portion is provided inside the cylindrical portion,
A closed bottom plate is extended inside the lower end of the pouring beak part, a thin wall portion for opening is formed in the closed bottom plate, and a knob means is continuously provided on the upper surface of the closed bottom plate in the thin wall portion, and At least a part of the beak part and the cylindrical part are connected by a liquid return passage formed by an inclined surface facing the notch, and the angle of the inclined surface is larger than the angle of the inclined wall of the container. is there.

<Operation> The above-mentioned spout plug is attached to the opening of the inclined wall of the container by a flange portion, and is opened by the pulling ring in use. When the contents are poured out by inclining the container, even if the contents turn around from the beak part, the liquid return passage returns to the container from the opening.

<Embodiment> The present invention will be described in detail below with reference to an embodiment shown in the drawings.

FIG. 1 is a vertical cross-sectional explanatory view of the pouring spout (A) of the present invention.
The spout plug (A) is integrally molded with a synthetic resin such as polyethylene and has a flange portion (1) attached to the periphery of an opening of a container body (not shown). A cylindrical portion (2) is projected and extends upward from the inner edge of the. The cylindrical portion (2) is provided with a screw (3) serving as a means for fitting with a resealing cap (not shown) like the ordinary spout stopper on the outer surface. Further, the cylindrical portion is provided with a beak portion (5) which is a trumpet shape and partially provided with a notch (4) as shown in FIG. 2, and a sealed bottom plate (6) is extended inside thereof. The closed bottom plate (6) is also continuous with the cylindrical portion (2), and a liquid return continuous to the closed bottom plate (6) between the inside of the cylindrical portion (2) and the outside of the beak portion (5). A passage (7) is provided, and the liquid return passage (7) is an inclined surface (8) whose apex is on the opposite side of the notch (4) as shown in FIG. Further, in the closed bottom plate (6), a thin portion (9) having a closed loop shape of a desired shape is formed inside the beak portion (5), and the closed bottom plate (9) in the thin portion (9) is formed. On the upper surface of 6),
A picking means including a pulling ring (11) is provided so that the root (10) is on the opposite side of the notch (4).

Next, a state in which the pouring plug (A) is attached to the opening (12) of the main body (B) of the Goebel top type liquid container will be described with reference to FIG. In FIG. 2, the pull ring (11)
Is shown with the pouring hole (13) being pulled in a desired shape from the thin portion (9), and the angle (α) of the inclined surface (8) of the spout (A) of the present invention is The inclination wall (14) of the container body (B) is larger than the angle (β) formed with the horizontal line, and the inclination surface (8) has an angle with respect to the horizontal line even when attached to the inclination wall (14), At the time of pouring or at the end of pouring, the residual liquid dripping from the beak part (5) returns to the inside of the container from the pouring hole (13) by utilizing the inclined surface (8). The liquid does not stay in (A).

Here, when the diameter of the spout plug (A) has to be provided within a limited size range, the inclined surface (8)
In some cases, the angle cannot be made large, but as shown in FIG. 3, it is possible to make the other structures substantially the same and to position the closed bottom plate (6 ') below the flange portion (1).

<Effect> The present invention is configured as described above and has the same opening property as that of the conventional spouting spout, but since it is poured out from the trumpet-shaped beak part, the liquid can be drained easily, and any residual liquid dripping from the beak part should be provided. Since it enters the container through the return passage, there is no dripping when pouring next time, and the pouring and spout itself can be kept clean.
