Description

[Detailed explanation of the invention] A. Purpose of the invention Industrial application field The present invention relates to simple disposable containers, such as paper packs for milk, juice, etc.

Prior art and its problems In recent years, paper cartons have been widely used as commercial containers for milk, soft drinks, and the like.

However, it is inconvenient that a considerable amount of force and effort is required to open this paper pack container, and small children and the elderly are often unable to open it properly.

In addition, all conventional simple containers such as paper packs have their spouts at the top, and in order to pour out the contents (hereinafter referred to as pouring), the angle of inclination must be changed depending on the amount of contents. First, since the inside of this paper pack cannot be seen, it is particularly difficult to adjust the degree of inclination, and if there is a large amount of liquid in it, it is necessary to lift the top to pour it into the top. It was difficult to get it out.

This invention was developed with the aim of solving these problems.It is easy to open, even children and the elderly can open it, and it is extremely convenient because the contents can be poured out at a constant angle of inclination. The present invention is intended to provide a lower dispensing container that is easy to use.

B. Structure of the invention The structure of the invention is to provide a pouring hole and an air hole having an appropriate interval with respect to the pouring hole in the lower part of a simple container such as a paper pack, and to connect the pouring hole and the air hole. A cover body is attached to cover the pouring hole, and the cover body is formed in such a way that when the upper attachment part is peeled off, the air hole is opened and the contents flowing out from the spout hole are received. The gist is a lower pouring container with a characteristic feature.

Means to Solve the Problem Two large and small holes were provided at an appropriate interval in the lower part of a container such as a paper carton, and the larger one was used as a pouring hole and the smaller one was used as an air hole.

Then, a cover body is pasted to cover the pouring hole and the air hole, and when the liquid flows out, only the upper pasted part of this cover body is peeled off to create a valley between the container body and the cover body. If the shaped part is used as a liquid receptacle and the liquid that flows out is caught in this receptacle, this liquid will accumulate in the receptacle and when the liquid level exceeds the spout hole and air hole, the liquid will no longer flow out. will stop.

However, if the container is tilted so that the spout hole is at the bottom, the air hole will be above the liquid level and the same volume of air as the amount of liquid that comes out of the spout will be supplied into the container from this air hole. They discovered that extremely smooth dispensing was achieved, and that if the container body was held upright without any tendency, the liquid would stop flowing out.

The present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the container of the present invention.

As shown in this figure, in the present invention, there is a container 1 in the form of a paper pack, for example, and two large and small holes are made in the bottom of the container, indicated by dotted lines, and the larger hole is the pouring hole 2, and the smaller hole is the pouring hole 2. This is the air hole 3. Incidentally, it is preferable that these two large and small holes are provided with a certain wide interval as shown in the figure. In addition, although there is no need to specifically limit the size of the pouring hole 2, the diameter is 6 to 6.
Approximately 10mm is suitable, and the size of air hole 3 is 2 to 4 in diameter.
A value of about mm is preferable.

Then, a cover body 4 covering these pouring holes 2 and air holes 3 is pasted.

In this embodiment, the cover body 4 has a triangular bent portion 5 at the end closer to the pouring hole 2.

It is preferable to attach the cover body 4 to the container 1 by making a seam 6 on the left and right sides and at the bottom, bending the edges, and firmly adhering the cover body 4 to the container 1 so that only the upper edge can be easily peeled off. I'll leave it there.

In the case of this figure, a continuous glue 6 is glued to the left of the folded part 5, and the left end of the cover body 4 inside this folded part 5 is simply bent without being glued to the left of the folded part 5. It is continuous. (3rd
(See figure) Further, preferable results can be obtained if the upper edge of the bent portion 5 is also adhered to the container 1 in a state where it can be easily peeled off.

Figure 2 is the cover body of Figure 1 (including the bent part)
FIG. 3 is a cross-sectional explanatory view of FIG. 2 viewed from above.

To open the container 1 as shown in these figures, the upper edge of the cover body 4 and the upper edge of the bent portion 5 are inserted into the container 1.
When the cover body 4 and the folded part 5 are peeled off from the cover body and the folded part 5 is opened from the front to the left, the cover body 4 and the folded part 5 are integrated to form a socket u.

In other words, the contents coming out of the pouring hole 2 are once received by this receptacle U and then poured out over the upper edge thereof.

On the other hand, this opening allows air to be easily supplied toward the air hole 3.

That is, by peeling off the upper part of the cover body 4, a gap is created between the cover body 4 and the container 1, from which air can easily flow toward the air hole 3.

Function The present invention has the above-mentioned configuration, and the contents are stored in the container 1 from the upper part in advance, and the upper part is sealed. When it is peeled off and the spout hole 2 and air hole 3 are opened as shown in Fig. 2, the contents flow out from these holes, but the liquid accumulates in the socket U and the liquid level is between the spout hole 2 and the air hole. Once it passes through the hole 3, the contents stop flowing out.

However, when the container 1 is tilted, the contents can be poured out from the pouring hole 2 very smoothly.

FIG. 4 is a perspective explanatory view for explaining the pouring principle of the present invention.

If the container 1 is tilted so that the spout hole 2 is at the bottom as shown in this figure, the air hole 3 will naturally be at the top, above the liquid level in the socket U and at the same time at the same time at the depth of the liquid level in the container. is considerably shallower than pouring hole 2.

As a result, the balance is disrupted and the contents s begin to flow out from the spout hole 2, and the suction force of this outflow forces air a to be sent into the container 1 from the air hole 3, which continuously displaces the contents. Promote the outflow of s,
Pour is achieved in an almost constant state during the tilt.

In this way, if the inclination of the container 1 is maintained at a constant angle, the contents s will be poured out from the spout hole 2 in a constant state, and air intake from the air hole 3 will also continue in a constant state.

In other words, the inclination angle of the container 1 can remain constant until the contents s come out, and there is no need to make any adjustments.

If this slope is eliminated and the spout hole 2 and the air hole 3 are returned to almost the same horizontal position, the pouring will stop, and even if the contents s remain, they will not come out from the spout hole 2. There isn't.

It goes without saying that care must be taken as the internal pressure may change due to changes in temperature or the pressure of the paper pack, etc., resulting in leakage.

In addition, in the container of the present invention, it is up to the user to choose whether or not to pour from the pouring hole 2, and there is nothing that prevents pouring by opening the upper sealing part with the cover body 4 attached. isn't it.

C. Effects of the invention The effects of the invention are listed below.

(a) Peeling off the upper part of the cover body is much easier than opening conventional paper packs, and even children and the elderly can easily open it.

(b) The spout is located at a low position, making it easy to pour.
Even if the container is full, there is no need to lift the container, and it can be easily poured while left in place.

(c) Since the liquid can be poured in a steady state by tilting at a constant angle, there is no need to adjust the tilt angle, and smooth pouring can be achieved even when the liquid level is not visible.

(d) If you remove the slope and place it on a flat surface, the pouring will stop.
Even if the contents remain, there is little risk of leakage.

As mentioned above, the present invention has very excellent effects, and can be used to store milk, juice, and other liquids in paper bags.
It can be used very effectively as a simple disposable container.
