DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail by way of examples.
As shown in FIGS. 1, 2, and 3, the container of the present invention comprises a blister box type box body comprising one frame member 10 and a pair of side surface closing members 20 and 20.
[0021]
In the frame member 10, a pair of side plates 12 and 12 and a cover plate 13 and 13 that face each other via a bottom plate 11 and a bottom plate are connected to each other via a folding line.
And the side surface orthogonal to a side plate is open | released, leaving the adhesive pieces 111 and 121 provided in a row by the bottom plate 11 and a pair of side plates 12 and 12, respectively.
[0022]
The bottom plate 11 and the adhesive piece 111 are connected to each other via a folding line, and both ends of the adhesive piece 111 are cut out by the height of the adhesive piece 12.
The side plate 12 and the adhesive piece 121 are connected continuously via a cutting line a. In addition to the single zipper line shown in FIG. 2, there are various cutting lines such as a perforation line, a half-cut line, and a cut tape, but the cutting line is not particularly limited to one type.
[0023]
When the adhesive piece 121 is assembled to the container, a knob portion 122 is provided on the upper portion thereof, and an annular peeling portion is formed by a half-cut line or the like within 5 cm, preferably 3 to 5 cm from the upper end of the knob portion. 123 is provided. This is a device that makes it easy to pinch the adhesive strip 121, and provides a trigger for pinching by providing a peeling portion on the top of the adhesive strip. The reason why it is within 5 cm from the upper end is to pinch the adhesive strip with a finger. This is a length necessary to prevent the adhesive strength of the container from being lowered (see FIG. 4).
[0024]
The cover plate 13 is provided with an outlet 131 for exposing a spout (not shown) provided in an inner bag (not shown) by a half-cut line or the like. The outlet may be provided on either side of the pair of lid plates.
The heights of the pair of lid plates 13 and 13 may not be the same as shown in FIGS.
[0025]
The side closing member 20 has a width dimension corresponding to an internal dimension between the pair of side plates 12, 12, and the lid piece 201 is connected to the upper end of the side closing member 20 via a folding line. It is installed.
Corner reinforcing ear pieces 21, 21 extending in the direction of a pair of side plates are connected to the vertical side edge of the side closing member 20 via a folding line.
[0026]
Each corner reinforcing ear piece 21 is divided into an adhesive piece 211, a reinforcing wall piece 212, and a reinforcing adhesive piece 213 in the direction of the side plate via a folding line.
The bending line between the pieces can be a weak line such as a lead ruled line, a perforated line, a half-cut line, or the like having a cut line at a predetermined interval. By making the line weaker, the work of crushing the corner reinforcing piece at the time of disassembling the container described later becomes easy.
[0027]
When the corner reinforcing ear piece 21 is bent into a triangular prism shape along the folding line and assembled into a container, the adhesive piece 211 plays a role of adhering to the side plate 12, and the reinforcing adhesive piece 213 is valley-folded to form the back side of the corner reinforcing ear piece.

Next, the pair of side surface closing members 20, 20 are folded along a folding line (only the reinforcing adhesive piece 213 is valley-folded), and the side surface closing member 20 is folded into two surfaces whose side surfaces orthogonal to the side plate 12 are open. Are attached from the inside, and the front side of the side surface closing member 20 and the back side of the adhesive pieces 111, 121, 121 are bonded to each other with, for example, a hot melt adhesive, and assembled into a box.
Finally, the back side of the side closing member 20 and the front side of the reinforcing adhesive piece 213 are bonded with, for example, a hot melt adhesive, and the corner reinforcing ear pieces 21 are assembled into a triangular prism shape, whereby the container of the present invention can be manufactured.
A series of these assembly operations can be easily performed using a Bliss box box machine.
[0031]
If an inner bag with a spout (not shown) filled with a content liquid such as sake is stored in a container and the lid plates 13 and 13 and the lid pieces 201 and 201 are closed, the inner bag is filled.
In use, once the lid plates 13 and 13 are opened and the outlet (not shown) of the inner bag is exposed and fixed to the outlet 131, the outlet 131 does not come off even if the container is tilted with the container closed. The content liquid can be easily poured out.
[0032]
The method for disassembling the container is as follows (see FIG. 5).
That is, first, the cover plates 13 and 13 are opened, and the inner bag (not shown) is taken out.
Next, when the upper portions of the pair of side plates 12 and 12 are placed and pulled outward, the side plate 12 is peeled off from the adhesive piece 211 of the side closing member, and the side plate 12 and the side closing member 20 are brought down by breaking from the cutting line a. The container will be flat.
[0033]
Alternatively, when the peeling part 123 provided on the knob part 122 of the adhesive piece 121 is held and peeled outward, the adhesive piece 121 is peeled off from the side closing member 20 and separated from the side plate 12 via the cutting line a. The container will be flat.
[0034]
When the triangular columnar corner reinforcing ear piece 21 of the side surface closing member 20 is crushed by the ruled line b and peeled off from the adhesive piece 111, the side surface closing member 20 becomes a flat state.
The pair of side surface closing members 20 and 20 are peeled off from the adhesive pieces 111 and 111, and the frame member 10 is also in a flat state.
[0035]
In this way, the container becomes the original flat frame member 10 and the pair of side surface closing members 20 and 20, and can be easily disposed of.
