Description

[Detailed description of the invention] The present invention is a pack-in box in which an inner container made of a flexible material such as a synthetic resin film is housed in a container made of corrugated paperboard. This invention relates to improvements in outlet support devices.

Conventionally, devices equipped with a device for projecting and fitting the spout of the inner container onto a desired location on the outer surface of the outer container to support the spout have been known as seen in Japanese Utility Model Publication No. 44-20871. It is being

When this kind of support device is used for a container made of corrugated paperboard, it is usually provided in a flap portion for sealing.

In this case, as shown in Figure 5, the folding line of the opening piece a, which is made up of a breakable weakened line that opens to allow the spout of the inner container to protrude from the outer surface of the outer container, is inside the corrugated board that forms the flap C. It is difficult to bend the core liner when it is provided in a direction perpendicular to the corrugation d of the core liner.If you try to forcefully bend it to open it, the force of the opening piece a causes the core liner to bend along the corrugation d of the core liner. There is a risk of breakage.

When such breakage occurs, the force with which the front edge of the opening piece a locks the spout projecting from the outer surface of the outer container becomes weak, making it difficult to use.

On the other hand, in the case shown in FIG. 6, where the folding line of the opening piece a is provided parallel to the waveform d of the central liner of the flap C (such a support device is known from Japanese Utility Model Application No. 146117/1983).

), it is easy to bend the opening piece a, but since the circular broken part e that fits the spout comes close to the bending line, it is difficult to close the opening piece a to lock the spout. There was a drawback.

The present invention eliminates the drawbacks that occur when these conventional support devices for the spout of an inner container are provided in a container made of corrugated paperboard, and is equipped with a support device that can reliably support the spout. A packaging container is provided, in which an inner container 2 made of a flexible material such as a synthetic resin film is provided with a spout 3, and an outer container 1 made of corrugated paperboard that houses the inner container 2 is provided with the spout 3. 3
A support device 4 for projecting and supporting the outside of the outer container 1
In the support device 4, the support device 4 includes a circular cut weakening line 5 provided at an arbitrary location on the outer surface of the outer container 1, into which the neck of the spout 3 fits, and the cut. On the left and right sides of the weakened line 5, there is a pair of weakened lines 8, 9 which are connected to each other so as to be perpendicular to the waveform 7 of the core liner 6 of the corrugated paperboard constituting the outer container 1. A weakened cut line 10, a weakened cut line 8, a weakened cut line 10, a weakened cut line 9, a weakened cut line 10, which are arranged perpendicularly to each other and are connected to the circular weakened cut line 5. and a folding line 11.12 connecting the ends thereof at an angle of approximately 45°.

1 to 4 show an example of the implementation of the present invention. To explain in more detail, the outer container 1 made of the corrugated paperboard has a rectangular parallelepiped shape, and the upper and lower sides of each side wall are connected to each other. Therefore, the inner flaps 1a, 1a and the outer flap l
b, lb are provided, and a spout support device 4 is provided on one side of the upper outer flap 1b.

Since the support device 4 is provided on the upper outer flap 1b, when folding and sealing the upper inner flaps 1a, 1a,
Notches 1c, 1 are provided on the lower surface of the support device 4.
c was established.

The inner container 2 is made of a synthetic resin film and has a cylindrical spout 3 with a removable stopper.

As shown in the second figure, the support device 4 includes a circular weakened cut line 5 having a diameter suitable for fitting the neck of the spout 3, weakened cut lines 8 and 9 extending from side to side, and It consists of a cut weakening line 10 extending perpendicularly to each of the lines 8 and 9.

The weakened cut line 8 and the weakened cut line 10, and the weakened cut line 9 and the weakened cut line 10 are each extended in a mutually inwardly curved shape, and have an angle of approximately 45° between their ends. They were connected by folding lines 11 and 12 composed of angular ruled lines.

Therefore, when in use, as shown in the third figure, the circular incision weakening line 5 is pressed to break and removed.

Next, the weakened cut line 8.9 and the weakened cut line 10 are respectively broken and opened outward along the folding lines 11° and 12.

The spout 3 of the inner container 2 is pulled out of the outer container 1 from the opening opened by this, and the neck of the spout 3 is fitted into a portion formed by cutting out a semicircular shape and fixed.

Further, as shown in the fourth diagram, a weak cut line 8 and a weak cut line 10 are formed.
Then, the front edge of the opening piece formed by the weakened cut line 9 and the weakened cut line 10 is inserted under the neck of the spout 3 and locked to complete support of the spout 3.

In the embodiment described above, the folding lines 11 and 12 are composed of ruled lines, but the object of the present invention is not hindered even if the folded lines 11 and 12 are not provided.

That is, since the folding lines 11, 12 are provided at approximately 45 degrees with respect to the corrugation 7 of the core liner 6 of the corrugated paperboard, it can be easily folded back.

In this case, each of the weakened cut line 8 and the weakened cut line 10 and the weakened cut line 9 and the weakened cut line 10 are extended in a mutually inwardly curved shape to further facilitate folding.

As described above in detail, according to the present invention, the folding line of the opening piece portion formed by breaking the cut weakening lines 8, 9, and 10 constituting the support device 4 is the center liner 6 of the corrugated paperboard. Since it is provided at an angle of approximately 45° with respect to the waveform 7, it can be easily folded back to open the opening, and by folding back the opening piece portion, a relatively large opening area is provided, and therefore, it can be used for interior decoration. Even when the position of the spout 3 does not match the position of the opening, it can be easily taken out, and furthermore, the front edge of the opening piece portion faces the neck of the spout 3 that is fitted and supported on one side. Because of this position, it can be easily inserted and locked under the neck of the spout 3.
