Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is designed to remove liquid adhering to the edge of the spout after pouring out the liquid inside the open container. The present invention relates to an open container with a spout that allows smooth pouring without dripping and flowing along the outer surface of the container.

(B) Conventional technology After pouring a highly viscous liquid such as paint or oil or a chemical liquid from the spout of an open container such as a beaker or jug, the spout rim or spout Materials adhering to the rim of nearby open containers dripped and flowed along the outer surface of the container, contaminating the container itself and the container storage area.

Ideas for dealing with such leakage from the backside include Utility Model Publication No. 55-49536 and Utility Model Application Publication No. 58-58.
No. 67746 has arrived.

These are designed to handle back leakage by providing a drip tray or groove to catch anything that drips from the edge of the spout, and prevent the dripping from returning to the inside of the container through the drip tray or groove. It was hot.

(c) Problems to be solved by the invention Conventional general spouts are horizontal, with the edge of the spout being a horizontal line as shown in Figure 5. It was sloped at an angle of about 30 degrees.

The fact that the spout edge line is nearly horizontal is a disadvantage in causing back leakage.

Therefore, Utility Model Publication No. 55-49536 and Utility Model Application No. 1983
-No. 67746 has back leakage.

Then, the leakage from the back was caught by the droplets and grooves.

However, with highly viscous paints, there is a problem in that the back leakage is thick, so that it drips over the drip tray and grooves and onto the outer surface of the container, making it impossible to catch the back leakage.

Furthermore, a highly viscous material has the disadvantage that it is difficult to flow inside a groove or cylinder, making it difficult to return to the inside of the container.

In addition, when pouring, it is important to note that it should not flow out only from the tip of the spout or the rim of the spout.
No. 49536 and Utility Model Application Publication No. 1982-67746 had the drawback that the depth of the spout was shallow and the amount of outflow was not small, making it difficult to use them practically.

Therefore, if the inclination of the container itself is increased in order to increase the amount of outflow, the outflow will also occur from the rim of the open container, forming a waterfall-like surface and making it difficult to pour. There was a drawback.

Even in a typical open container with a spout, it was difficult to see any leakage from the spout alone.

Therefore, if the mouth of the container receiving the pouring was small, the width of the water flowing out in a planar shape like a waterfall would become wider, and it would not be able to fit into the small mouth and would spill over, making it difficult to pour. .

The problem that this invention aims to solve is that there is no leakage from the spout rim or the mouth edge of the open container, and the outflow state is not planar but rod-shaped, which allows smooth pouring into small-mouth containers. It is to do so.

(d) Means for solving the problem The mouth rim 2 of an open container with a spout, such as a beaker or a pitcher, is provided with a tongue-shaped spout 3 protruding from a part of the mouth rim 2 of the open container 1. A side wall is provided as a prevention wall 4, increasing in height at an upward angle from a predetermined location on the side of the mouth edge 2 to above the tip of the tongue-shaped spout 3.

It is effective to determine the position and angle of this prevention wall 4 by considering the condition created by the position and angle of the water surface relative to the cup that is created when a cup half-filled with water is tilted sideways. .

The prevention walls 4 are provided on the left and right sides of the tip of the tongue spout 3.

Then, the edge of the prevention wall 4 that stands above the tip of the tongue-shaped spout 3 is defined as a spout edge 5, and the left and right spout edges 5 meet as required with the tip of the tongue-shaped spout 3 as an intersection point. A V-shaped spout 6 consisting of an angle is formed.

The area of the spout 6 changes depending on the angle formed by the left and right spout edges 5, and can be increased by forming the straight line of the spout edge 5 into a curved line.

The surface of the spout 6 may be vertical, or may be inclined outward or inward.

The intersection point of the left and right spout edges 5 is preferably placed inside the tip of the tongue-shaped spout portion 3, and an appropriate interval as large as a water drop may be provided between the intersection points.

The corners of the prevention wall 4 may be rounded or the edges thereof may be curved to add aesthetic appeal.

(E) Function In the open container with a pouring spout according to this invention, when pouring out a container filled with paint, etc. up to the mouth edge 2 of the open container 1, the paint, etc. forms a tongue-like shape. At the same time as it flows out from the spout part 3, the paint and the like adhere to the left and right prevention walls 4, so that it does not flow out to the outside.

That is, even if the open container 1 is tilted greatly, paint etc. will not flow onto the mouth edge 2.

The state in which paint, etc. flows out from between the left and right spout edges 5, which are the edges of the prevention wall 4 that stands above the tip of the tongue-shaped spout 3, is poured out in a rod-shaped flow. Become.

The edge portions that come into contact with paint or the like during pouring are the tip of the tongue-shaped spout portion 3 and the left and right spout edges 5 of the prevention wall 4.

Therefore, when the open container 1 is placed upright after dispensing is stopped, the left and right spout edges 5 are the only edges on which the paint and the like flow.

These left and right spout rims 5 are in a standing state.
The dripping and flowing state of paint etc. adhering to the container flows along the spout edge 5 to the tip of the tongue-shaped spout 3, and flows into the container as the tongue-shaped spout 3 inclines inward. .

For this reason, it is effective that the angle formed by the left and right spout edges 5 is narrower than 90 degrees, and as the angle becomes wider than 90 degrees, outward flow from the spout edges 5 becomes more likely.

In addition, if the surface of the spout 6 is tilted and the paint adhering to the spout rim 5 flows at a 90-degree angle, it will flow straight downward along the spout rim 5 at a fast rate and flow into the container. 90 to the inside of the container.
If the angle is from about 45 degrees to about 45 degrees, there will be a considerable amount of dripping outward from the spout edge 5.

However, as the spout becomes more horizontal than about 45 degrees inward, it becomes similar to that of a conventional spout, and drips outward.

When the surface of the spout 6 is tilted outward, as the inclination becomes horizontal, paint etc. adhering to the spout edge 5 drips like drops to the outside of the container.

The flow of paint etc. adhering to the spout edge 5 according to the present invention can be explained in another way as follows.

When a thin rod is inserted into paint or the like and the rod is pulled out vertically from the paint or the like, the paint or the like flows straight downward in the form of a rod.

When this vertical rod is placed horizontally, the paint, etc., drips down like a waterfall or drips down, which is different from the conventional back leak. This is a phenomenon where the flow becomes planar, like a waterfall.

That is, in the open container with spout according to the present invention, leakage does not occur from the inside and the pouring state is rod-shaped.

(f) Examples Example 1 FIG. 1 is a side view showing Example 1, and FIG. 2 is a front view showing Example 1.

In the first embodiment, the side wall that gradually becomes higher at an upward angle from the lateral center point 7 of the mouth edge 2 of the open container 1 toward the tip of the tongue-shaped spout 3 is formed into a tongue-shaped spout. 3 is provided on the mouth edge 2 as a prevention wall 4.

The prevention wall 4 has a generally triangular shape that is angled at about 30 degrees from the lateral center point 7 of the mouth edge 2 when viewed from the side of the container.

The prevention walls 4 are provided in pairs from the tip of the tongue-shaped spout 3 to the mouth edge 2 on both the left and right sides.

As shown in FIG. 2, the spout 6 is formed at an appropriate angle such that left and right spout edges 5 are inclined left and right from the tip of the tongue-shaped spout 3.

It is effective if the angle formed by the left and right spout edges 5 is narrower than 90 degrees, and as the angle becomes wider than 90 degrees, the flow speed along the spout edges 5 slows down, causing sagging to the outside. There is a possibility.

Ideally, the surface of the spout 6 formed by the left and right spout edges 5 should be vertical, but it is also effective if it is slightly tilted inward.

However, it is not preferable to have the surface of the spout 6 tilted outward, since there is a possibility that substances adhering to the spout edge 5 may drip outward.

Example 2 FIG. 3 is a front view showing the second embodiment.

In the second embodiment, the intersection point of the left and right spout edges 5 is provided inside the tip of the tongue-shaped spout portion 3, and an appropriate interval of water drop size is provided between the intersection points.

The intersecting points provided with this interval make it easier for things adhering to the left and right spout edges 5 to flow together into the tongue-shaped spout portion 3 and then into the container.

The shape of the prevention wall 4 is generally triangular, but the corners may be rounded, or the edges of the prevention wall 4 may be curved to create an aesthetic sense. Naturally, it is conceivable to create a shape with the addition of .

Example 3 FIG. 4 is a front view showing the third embodiment.

In the third embodiment, the straight line of the spout edge 5 is formed into a curved line, so that the surface of the spout 6 is made large.

By enlarging the surface of this spout 6,
This makes it easier to use for powders and granules.

(g) Effects of the invention When using the open container with spout according to this invention, leakage from the mouth edge 2 of the open container 1 will not occur even if the open container 1 is tilted significantly.

Therefore, Utility Model No. 55-49536 and Utility Model Application No. 58-
There is no need to provide a structure such as a drip tray or groove to deal with back leakage as in No. 67746, and back leakage does not occur from low to high viscosity products.

The state of the material flowing out from the spout 6 during pouring is always in the form of a rod, whether it is a small amount or a large amount.

Therefore, it is possible to precisely pour the liquid onto the recipient's location, and it is possible to smoothly pour the liquid into a container with a small mouth.

Furthermore, it can be used not only for liquids but also for powders and granules.
