JPS6020576Y2 - Packaging box for storing pleated plastic bags - Google Patents

Description

[Detailed description of the invention] This invention is made of polyethylene film, etc., and has pleats on both sides of the bag, which are suitable for storing foods, etc., and stacks a large number of them in an orderly manner. , and - it relates to a packaging box that can be easily taken out one by one.

Generally, pleated plastic film bags are
Both sides of the cylindrical film are folded inward to form pleats, and the bag is handled in a flat state, so in this handling state, the film becomes four-fold on both sides in the longitudinal direction.
The film is only doubled in the center of the bag, so when many pleated bags like this are stacked, the center is only half the height and thickness of both sides, resulting in dents. If the bags are stored in a normal packaging box and transported, they will shift toward these dents, disrupting the neatly stacked condition, and the bags may become bent or wrinkled, making it difficult to take them out one by one. There were drawbacks such as:

The packaging box of the present invention is designed to prevent such pleated bags from shifting during transportation in an orderly stacked state.

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 shows the packaging box of the present invention developed and shown in which the front wall 1, the right wall 2, the rear wall 3, and the left wall 4, each forming a rectangular shape, are connected by folding lines 5°6.7. Furthermore, a connecting piece 9 is provided at the left end of the left side wall 4 via a fold line 8.

Each of the side walls 1, 2. 3.4, bottom pieces 11, 12, 13, and 14 are extended through the straight fold line 10 on the lower side of each side wall 1.3.4. 2.3. A lid piece 16. 17. 18. 19 will be extended.

Furthermore, a folding piece 21 is provided extending from the tip of the pair of opposing lid pieces 17 and 19 via a folding line 20, and the folding line 20
Cuts 22 are provided at the left and right end positions.

Further, the other pair of lid pieces 16 and 1B are each provided with a deep cut groove 23 in the center, and the lower end straddles the deep part of the cut groove 23 and further straddles the fold line 15, and the lower end is connected to the front and rear side walls 1 and 1B. A locking piece 25 is formed by providing a notch 24 in the shape of a mouth.

A folding line 26 is provided at the lower end of the locking piece 25.

Furthermore, the lid piece 1 is placed across the fold line 15 in the center of the right side wall 2.
An n-shaped perforation line 27 is provided in the length reaching the lower side of the opening 28 to form an entrance part 28.

In this Ibunguchi part 28, there is a fold line 2 at the center height position of the right side wall 2.
9 will be provided.

Next, to explain how to assemble this packaging box, first, the front, rear, left and right side walls 1. 2. 3. 4 as a fold line 5. 6. At 7, the connecting piece 9 is bent in the same direction at right angles as shown in FIG.

Next, each of the bottom pieces 11, 12, 13, and 14 is bent inward at right angles along the fold line 10 to form a closed bottom wall as shown in FIG. A large number of attached plastic film bags are stored in a stack.

Next, the locking piece 25 separated at the notch 24 is made to stand up, and the remaining lid pieces 16 and 18 are bent inward at right angles along the fold line 10, and then the lid pieces 17 and 19 are bent inward at the fold line 10. Further, the bent piece 21 is bent downward along the fold line 20, and the two opposing pieces are pushed into the cut grooves 23 of the lid pieces 16 and 18 so as to overlap.

Then, attach the locking piece 25 standing up as described above to the fold line 1.
5 and 26, press from the tip of the locking piece 25 along the lower surface of the lid pieces 17, 19 to engage the notches 23 and 22 with each other, as shown in FIGS. 3 and 4. The overlapped bent pieces 21, 21 are fixed in a vertical position, and the closing of each lid piece 16, 17, 18, 19 is also fixed as shown in FIG.

The pleated plastic film bags stacked and stored in the packaging box configured as described above are restrained by lightly pressing the upper space in the center by the folding piece 21, so that the stored bags are always stable. It will not cause any misalignment.

In order to take out the bag housed in this packaging box, the opening part 28 can be easily opened by pulling the part above the fold line 29 between the fold lines 15 and pulling it, as shown in FIG. The stacked bags can be taken out one by one starting from the top.

When the number of stored bags is running low, the sewing machine rule 27 is separated from the fold line 29 to the fold line 10 as shown in Fig. 8, and the entire Ibun opening section 28 is opened. You can easily take it out.

As described above, the packaging box of the present invention prevents the plastic film bags stacked inside the box from shifting by pressing the plastic film bags stacked inside the center concave area from above with a folded piece. Therefore, it is advantageous to avoid clutter, bending, or wrinkles during transportation.

Additionally, it has the advantage that it can be easily taken out one by one from the Ibun mouth, making it extremely valuable in practical use.
