Description

[Detailed description of the invention] [Field of industrial application] The present invention is a so-called composite container, which is formed from a wall plate with a synthetic resin film coated on the inner surface of thin aluminum plates or paper. This invention relates to a spout in a liquid container.

[Conventional technology]

A liquid container whose container is formed from a thin aluminum plate or a wall plate made of paper or a laminated sheet of paper and aluminum foil with a synthetic resin film coated on at least the inner surface is inexpensive and easy to dispose of. They are widely used as containers for milk, juice, etc. because they are easy to mold, lightweight, and convenient to handle.

[Problems to be solved by the invention] As described above, the simple container, which is generally called a composite container, has many excellent functions and effects, but when opening it, it is necessary to separate it from the container. Because the opening shape of the spout is not uniform, it is not possible to obtain a stable pouring operation, and it is impossible to keep the container sealed after opening.
There were drawbacks and dissatisfaction, such as that the liquid content had to be consumed within a very short period of time.

The inability to seal the container once it is opened is a serious disadvantage, especially when the contents need to remain in the opened container for a period of time such that the liquid becomes like oil or mustard oil rather than juice or milk. Therefore, this type of container cannot be used as a storage container for show oil or other oils, and the scope of use of the composite container, which has the many excellent functions and effects described above, has been greatly narrowed.

The present invention was devised to solve the problems, shortcomings, and inconveniences of the conventional examples described above, and aims to make it possible to easily and effectively open the container and to seal it after opening. be.

[Means for solving problems]

Hereinafter, the present invention will be described with reference to drawings showing embodiments of the present invention.

In the present invention, a container 1 is formed of a wall plate 2 constructed by coating a synthetic resin film 4 on the inner surface of a main plate 3 which is a thin aluminum plate, paper, or a laminate of paper and aluminum foil. This relates to the spout formed in the top plate part 5 of the spout, in which a plate 9 is integrally attached to the lower end of the spout tube 7 in the shape of a brim,
Further, the resected piece 11 with a knob 12 implanted at the lower end of the inner circumferential surface of the pouring tube 7 is connected via a thin connecting piece 13 that is easy to break, and furthermore, a large number of pointed pieces are arranged to surround the resected piece 11. A spout body 6 made of soft synthetic resin is provided with a broken protrusion 10 hanging from the lower end of the spout tube 7 at a height not exceeding the lower surface of the cut piece 11,
A part of the main plate 3 in the top plate part 5 is cut out and the lower surface of the cut piece 11 is fixed to the exposed resin film 4, and then the dispensing tube is fixed to the top plate part 5 by a plate 9. A cap 15 for sealing the spout body 7 is detachably attached to the spout body 6.

The spout tube 7 forms a spout tube for the opened container 1, so it has a shape that allows stable dispensing of the liquid content and a shape that allows for good liquid drainage. It is desirable that this is set.

For mounting, the plate 9 is a part that tightly fixes the spout body 6 to a predetermined location of the top plate part 5 by appropriate means. In addition, in order to hold the pouring tube 7 in a stable posture, it is preferable that the width of the pouring tube 7 is relatively wide and the joint area to the top plate portion 5 is large.

A connecting piece 13 that integrally connects the cutting piece 11 to the lower end of the inner circumferential surface of the spouting cylinder 7 in a manner that substantially closes the spouting cylinder 7 can be easily cut and removed when removing the cutting piece 11. The structure is such that the piece 11 can be easily removed, and the spout tube 7
It may be several strips connecting the cut piece 11 and the cut piece 11,
It may be a thin piece that is integrally shaped over the entire outer circumference of the cut piece 11.

The knob 12 implanted in the resected piece 11 is desirably shaped so that when unsealing the container 1, the user can easily apply a lifting force to the resected piece 11 by picking the knob 12 with the fingertips. They are shaped like a ring on the tip that can be easily caught by a finger, or a rod with a large part on the tip.

In this way, the shape of the knob 12 may be such that it can be easily pinched with the fingertips, but the connecting piece 13 can be easily severed by the pulling force acting through the knob 12. As shown, this knob 12 is connected to the connecting piece 1.
It is advantageous to implant the circumferential edge of the resection piece 11 close to 3.

The cap 15 is detachably attached to the spout body 6.
Before the container 1 is opened, the spout body 6 prevents dirt from entering the spout tube 7, and after the container 1 is opened, the spout body 6 forms a spout.
helps to seal it.

The spout body 6 is fixed to the container 1 by the top plate portion 5 of the container 1.
The resin film 4 is exposed by cutting only a portion of the main plate 3 at a desired location (preferably the peripheral edge as much as possible) to a size that includes the entire broken protrusion 10.
With the lower surface of the resection piece 11 glued and fixed to the plate 9,
This allows it to be firmly fixed to the top plate portion 5.

[Effect]

Since the present invention has the above-mentioned configuration, the resection piece 1
Before the container 1 is cut out, the entire inner surface of the container 1 is completely covered with the resin film 4, so that complete sealing is ensured.

In order to unseal the container 1 from this state, the knob 12 is picked up with the fingertips and pulled up, and the connecting piece 13 is cut by this pulling force, and the cutting piece 11 is removed from the spout body 6.

That is, by applying a pulling force to the knob 12, the connecting piece 1
3 and pull up the cut piece 11, this cut piece 1
The resin film 4 fixed to the lower surface of the container 1 is also pulled up together.

The resin film 4 is pulled up together with the cut piece 11 and slightly elongated, but it immediately hits the pointed breakage piece 10 and is broken by the breakage piece 10. Only the portion surrounded by the cutout piece 11 is cut off together with the cutout piece 11, and the container 1 is opened by breaking the part of the resin film 4 that is integrated with the cutout piece 11.

After opening the container body 1 described above, the liquid content may be poured out of the container 1 through the spout tube 7 by tilting the container 1.

Further, after opening, the container 1 can be sealed by assembling the cap 15 to the spout body 6, so that the liquid content can be kept sealed for a relatively long period of time without any trouble.

As is clear from the usage mode of the present invention, the large number of breaking protrusions 10 can be arranged so that the resin film 4 can be immediately broken when the resin film 4 is pulled up together with the cut pieces 11. Therefore, it is desirable that the breaking protrusion 10 is suspended at a height that allows the tip to be positioned as close to the bottom surface of the cut piece 11 as possible without exceeding the lower surface of the cut piece 11.

〔Example〕

In the case of the illustrated embodiment, the spout tube 7 is designed to stabilize the dispensing operation of the liquid contained therein, to ensure good drainage of the liquid, and to more reliably achieve sealing with the cap 15.
It is shaped into a trumpet-like shape that widens toward the top.

In addition, an enlarged portion 8 is provided at the lower end of the outer circumferential surface of the spouting tube 7, and has an outer diameter larger than the outer diameter of the upper end of the spouting tube 7, and the cap 15 can be assembled to the spout body 6 only partially. is provided.

Various means are possible for fixing the spout body 6 to the top plate part 5, but in the case of the embodiment shown in FIG. The cutting piece 11 and the mounting plate 9 are fixed to the cut and exposed resin film 4, and the assembly is formed into a flat ring plate shape with a size that extends over the upper surface of the plate 9 and the outer surface of the main plate 3. 14 is used to connect the plate 9 and the main plate 3.

In the case of the embodiment shown in FIG. 3, as is clear from the above-mentioned configuration, the plate 9 is fixed directly to the resin film 4, the plate 9 has approximately the same thickness as the main plate 3, and the mounting The main point is that the plate 14 is a separate body from the spout body 6, and any suitable plate can be used.

As a means for the second assembly, as shown in FIG. To install the plate 9 between the main plate 3 and the resin film 4, the plate 9 is inserted and fixed, and the cut piece 1 is attached to the exposed resin film 4.
1 is fixed.

In the case of the embodiment shown in FIG. 5, the plate 9 is mounted between the main plate 3 and the resin film 4, so it is thought that the strength of the spout 6 can be achieved in the strongest manner by assembling the spout 6 to the top plate part 5. However, it seems that installation requires relatively troublesome work to position the plate 9 between the main plate 3 and the resin film 4.

A third means shown in FIG. 6 is to cut out a desired portion of the main plate 3 of the top plate portion 5 to a size that includes all the breakage protrusions 10,
Mounting is carried out by fixing the plate 9 to the upper surface of the main plate 3 while the cutout piece 11 is fixed to the exposed resin film 4.

In the case of the embodiment shown in FIG.
The adhesion strength to the top plate portion 5 is thought to be weaker than in other examples.

As described above, various means can be used to assemble the spout body 6 to the container 1, but the embodiment shown in FIGS. For installation, the plate 9 is directly fixed to the resin film 4, so even if the resin film 4 is removed, the end face of the main plate 3 will not be exposed to the liquid pouring passage, and this will prevent direct contact with the main plate 3. The embodiments shown in FIGS. 3 and 5 are suitable for storing liquid contents that should not come into contact with the container.

On the other hand, in the embodiment shown in FIG. 6, the end surface of the main plate 3 is exposed to the liquid pouring passage formed by cutting out the resin film 4. Not suitable for storage.

[Effect of idea]

As is clear from the above description, the present invention is capable of forming a substantially constant opening at all times, and the content liquid is poured out from this opening through the pouring tube 7, so that it is stable and good. A pouring action can be obtained, and before the container 1 is opened, the resin film 4 that is torn at the time of opening is integrated with another resin film 4, so the container 1 can be kept tightly sealed. , and a spout body 6
The structure is simple and it is extremely easy to assemble to the container 1, so it is easy to implement, and furthermore, even after the container is opened by cutting out the cut piece, the spout formed by the spout body can be opened and closed by the cap. Therefore, it has many beneficial effects such as being able to be stored and maintained for a long period of time after opening.
