DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
<Example of first bag>
The example of the 1st bag body 10 suitable for FIGS. 1-3 was shown. The bag body 10 is made of kraft paper as a double bag. The structure is somewhat complicated, and at the processing stage of bag making, the unit sheets are overlapped in one direction to form a double-end open overlapping sheet as a whole. Edges in the overlapping direction of the sheet 11 are indicated by 11a and 11b. Appropriate positions of the overlapping portions are joined, in particular, by gluing. The vicinity of the edges 11a and 11b in the overlapping direction and the vicinity of the opening edges at both ends are joined by gluing.
[0019]
Although the opening state of both ends of the stacked sheet is shown in FIG. 3 (A), it is noted that in FIG. 3 as a whole, it is shown as a single sheet in order to avoid complication of the drawing. I want.
As shown in FIG. 3 (A), slit lines 12 and 12 are formed from the open ends on both sides of the both sides as shown in FIG. 3A, and toward the base of the slit line 12. The diagonal first mountain fold line 13A is formed from the base points P0, P0 of the side edges. These first mountain fold lines 13A and 13A are connected to each other by a second mountain fold line 13B. In addition, first valley fold lines 14A and 14A connected to the first mountain fold lines 13A and 13A at points P and P are formed in parallel with the slit lines 12 and 12 on the outside thereof. On the other hand, the second valley fold line 14B is formed only on one side. Note that each of these fold lines is formed at the stage of bag making.
[0020]
As shown in FIG. 3B, the second valley fold line 14B, the first mountain fold line 13A, A surface surrounded by 13A and the second first mountain fold line 13B is folded to the one surface side. Further, the surface surrounded by the slit lines 12 and 12 and the first mountain fold lines 13A and 13A is folded on the one surface side as the first bottom surface flap F1. At this time, the second bottom surface flap F2 having a hat-like shape is formed by diving around the first valley fold lines 14A and 14A, and is positioned on the first bottom surface flap F1.
[0021]
As shown in FIG. 3C, continuously, first, or simultaneously, straddling the opposing first bottom surface flaps F1, F2 and under the opposing second bottom surface flaps F2, F2. The first bottom sheet 15A is joined by gluing.
Thereafter, as shown in FIG. 3D, a second bottom sheet 15B having approximately the same shape as the first bottom sheet 15A is brought in, and the first bottom sheet 15A, the first bottom flaps F1, F2, And it is joined to the second bottom surface flaps F2, F2 by gluing.
Thus, the bag 10 shown in FIGS. 1 and 2 is produced.
[0022]
<First packaging form>
As shown in FIGS. 1 and 2, the bag body 10 that has been made is a bottomed bag body that is open on one side, and has a flat shape in an unwrapped state. At the stage of loading, at least the bottom portion has a substantially rectangular shape.
These unwrapped bag bodies 10, 10... Are stacked in a substantially horizontal state in or near the packaging facility, as shown in FIG.
The packaging equipment is equipped with vacuum cups 20, 20, and the bags 10 are taken out one by one from the stacked bag bodies 10, 10... And placed on a loading line (for example, a loading conveyor shown in FIG. 5) 30. Installed.
[0023]
Next, the inside of the bag body 10 is opened by, for example, the vacuum cups 20, 20 or the grippers 21, 21, and air is blown from the openings to open the bag body 10 as a whole. At this time, the base points P0, P0 are buried in a part of the plane as the bag is opened, and instead, the points P, P connecting the first mountain fold lines 13A, 13A and the first valley fold lines 14A, 14A, At P..., Each corner point on the bottom surface becomes a substantially rectangular bag 100 as shown in FIG.
At this time, since the rigidity of the bottom surface is reinforced by the first bottom sheet 15A and the second bottom sheet 15B, the bag body 100 having a substantially rectangular shape is likely to be formed. Conversely, the first bottom sheet 15A and the second bottom sheet 15B are at least the same or smaller than the quadrangle surrounded by four points P, P, P, and P. In this case, it is desirable that the side of the sheet is not separated by 3 cm or more from the side of the quadrangle.
[0024]
Thereafter, as shown in FIG. 6, a plurality of integrated packages 50 in which primary packaging is performed are loaded in the bag body 100 in a substantially horizontal direction, and a plurality of packages 50, 50 are arranged at least at the bottom. Then, the opening is sealed.
Here, the package 50 is a primary package in which a standard product is accumulated. As an example of this, an example of a toilet roll 51 is given as an example of a regular product (a product having a fixed shape, and thus not a powder or the like). The toilet rolls 51, 51... Are grouped in a stacked state in a step and a side, and in the illustrated form, four are arranged in a stacked state in a three-stage stack, and are formed in a substantially rectangular parallelepiped shape by a packaging film such as a polyethylene film. It is an integrated product that is packaged in a primary package and can be taken home after purchase. This integrated product has a substantially rectangular parallelepiped shape, which is a package 50.
[0025]
When the package 50 is loaded into the bag body 100, it can be pushed in by the pusher 60 facing the opening. In this case, it is desirable to push in the plurality of arranged packages 50.
When loading is completed, as shown in FIG. 7, the openings are sequentially folded and folded by a folding device, and the lid sheet 16 is glued with kraft paper to seal the openings.
[0026]
Thus, the disposal of the bag body after the product is taken out at the store becomes simple. In addition, the cost can be reduced as compared with the case where a cardboard case is used. In addition, a packaging structure having sufficient strength to withstand physical distribution can be obtained. Further, as in the case of the cardboard case, the predetermined shape can be maintained, and it can be used for physical distribution without being out of shape.
[0027]
<Other packaging forms>
When the package 50 is loaded into the bag body 100, as shown in FIG. 8, the package 50 can be loaded into the bag body 100 in a stacked state. When the opening is sealed, as shown in FIG. 8, the opening can be sealed by fixing the folded / folded portion with the adhesive tape 17.
[0028]
In the present invention, as a regular product, in addition to a toilet roll, household roll paper such as a kitchen roll is desirable, but an integrated product in which tissue paper storage boxes are integrated can also be used. Furthermore, other appropriate articles are also objects of the fixed form. As a means for integrating the shaped objects, in addition to the film packaging of the above example, the packaging may be integrated by box packaging, bands or tapes.
On the other hand, in the present invention, the primary package of a standard product is used as a package, and the standard product itself is also included as a package.
[0029]
As a packaging bag to be used, a single kraft paper bag, a triple or more kraft paper bag, a bag of other pulp types, and a plastic sheet are also possible. However, a plastic sheet having an excessively high flexibility is difficult to maintain in a rectangular parallelepiped shape, so that a paper sheet is optimal.
[0030]
As a bag body, as shown in FIG. 9, it is set as the gusset bag body 55, and can take the structure where a bottom part makes a substantially square shape at the time of packaging. Other structures can be selected as appropriate.
In the present invention, the “rectangular shape in which the bottom portion has a substantially quadrangular shape” does not mean an exact quadrangular shape, but allows a slight collapse of the quadrangular shape.
[0031]
【The invention's effect】
As described above, according to the present invention, the disposal of the package after the product is taken out at the store is simplified. By using a bag as the packaging body, the cost can be reduced as compared with the case where a cardboard case is used. Further, as in the case of the cardboard case, the packaging is performed while maintaining the predetermined shape, and the product can be used for physical distribution in a state in which the predetermined shape is maintained without being deformed.
