Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pouring lid for a container of liquid such as edible oil.

Lids for dispensing liquids, such as cooking oil, generally have a problem in which the cooking oil adheres to the outer wall of the spout during pouring, causing the outer wall of the container to sag, making the container and its surroundings unsightly and unsanitary. There was a big problem. To this end, various types of lids have been developed to prevent this oil dripping, but no lid that has a sufficient oil dripping prevention effect has yet been developed.

As a result of various studies in order to develop a spout lid that does not drip one liquid, for example, oil, the inventors of the present invention formed a double spout end having a recurved part and a plate-like protrusion, and between them formed a spout lid that did not drip oil. It was discovered that a lid with holes almost completely prevents oil dripping, and based on this discovery, the present invention was completed.

That is, the present invention has a container opening fixing tube and a spout tube, the spout end of the spout tube is curved outward, and the base V of this curved portion is used to prevent the liquid adhering to the spout end. A pouring lid for a liquid container, characterized in that a return hole is provided protrudingly, a plate-like projection is formed at the bottom of the return hole, and the tip of the plate-like projection is located inside the tip of the recurved portion. be.

Hereinafter, an explanation will be given with reference to the embodiments shown in the drawings.

The container opening fixing cylinder 1 is a part for fixing the pouring lid to the container opening, and any fixing means is not restricted. Examples of fixing methods include screwing,
Examples include fitting.

In each embodiment, a protrusion is formed on the bottle mouth, and a protrusion is formed on the inner wall of the cylinder for fixing the container mouth, and when these two protrusions fit and lock, the five-piece lid is attached to the bottle mouth. Although these protrusions are fixed, all of these protrusions are omitted in the drawings.

The spout tube 2 is a part for pouring out the liquid contents, and is usually raised from the top surface of the tube fixed to the opening of the container. This pouring tube is Example 1
In addition to the cylindrical shape shown above, various shapes can be taken, such as a cylindrical shape with a U-shaped cross section, an elliptical cylindrical shape, and a rectangular cylindrical shape. Further, the height thereof may be such that, for example, the plate-like protrusion is directly connected to the top surface of the fixing cylinder.

The spout end is curved outward to form a curved portion 3. This recurve part needs to have a certain length, and it is desirable that the width when viewed from directly above (e in Figure 1) is 3 or more. In addition, when the container is placed upright, the liquid contents adhering to the back surface 4 of this recurved portion are exposed to the inner surface of the container.
It is necessary that the slope be provided so that it returns to the top. The recurved portion may be provided all around the circumference as in the embodiment shown in FIG. 1, or may be provided partially around the circumference as in the embodiment shown in FIG.

The base of the reversible part is provided with a return hole 5 for returning the liquid contents that have landed at the spout end into the container.

This return hole may be provided over the entire circumference or may be provided only in a portion. In the embodiment shown in FIG. 1, intermittent V holes are provided over the entire circumference.

A plate-like protrusion 6 is formed in the lower part of the return hole.

The distance between this plate-like protrusion and the back surface 4 of the recurved part is such that droplets of the contents can adhere to both surfaces and form a so-called purinone between the two surfaces, and when the container is placed upright, the liquid It is preferable that the return hole is such that it can return to the container through the return hole, but it may be wider than that.

This spacing will vary depending on the physical properties of the liquid contents, particularly surface tension and viscosity. For example, in the case of edible oil, about 2 to 5 pits are appropriate. When the droplet bridge is broken at the tip of the plate-like protrusion, most of the droplets that formed the V-shaped bridge adhere to the back side of the recurved part, and no liquid adheres to the back side of the tip of the plate-like protrusion. It is necessary to position the
Therefore, the tip of the plate-like protrusion must be located more inward than the tip of the recurved portion. The plate-like protrusion does not have to be parallel to the recurved portion, and the distance between the two on the inner side may be wider or narrower than the distance at the tip.

Such a pouring cylinder part does not have to be formed integrally. The first part shows an example of forming the spouting lid of the present invention, which was created by newly attaching a spouting tube to a conventional spouting lid (FIG. 3).

When the pouring lid of the present invention is used, the contents are mainly poured out from the pouring lower during pouring, but some of the contents are poured out through the return hole 5 and along the back surface of the recurved portion. When dispensing is finished and the container is placed upright, the liquid adhering to the tip of the recurved portion will travel along the back surface of the recurved portion and return to the inside of the container through the return hole. Due to the design on the back of the reversible part, liquid that has adhered to the container will return into the container through the return hole without dripping onto the outer wall.

The pouring lid of the present invention may be used as a replacement lid, or may be used as a packaging container by being attached from the beginning.

The pouring lid of the present invention can be used not only for bottles but also for cans. Although the type of liquid content is not limited, it is particularly suitable as a pouring lid for liquid foods.

The dispensing lid of the present invention has almost no risk of the liquid adhering to the outer wall when dispensing, is stable and easy to manufacture, and is simple to operate.Therefore, the present invention is extremely significant. .
