JPS607319Y2 - Cardboard box without partitions - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a cardboard box that does not require partitions.

Conventionally, a cardboard box for storing a plurality of bottles (hereinafter simply referred to as a cardboard box) has a lattice-like partition, and each bottle is stored in each partitioned space.

Although such partitions prevent bottles from being damaged during transport, they are time-consuming to assemble and insert, and they complicate equipment, especially when automating box assembly, bottle insertion, and other tasks. It was a time-consuming process.

The present invention provides a cardboard box that can safely store bottles without the need for such labor-intensive partitions, and is characterized by having an adhesive layer partially or entirely provided on the inner bottom to prevent the bottles from slipping. This is a cardboard box that does not require partitions.

The adhesive layer referred to in this invention is a layer that exhibits some adhesion to the surfaces of bottle materials such as glass, ceramics, metal, and plastic, but is easily peeled off and does not stain those surfaces. Any material that adheres well is fine.

Examples of such adhesives include melt adhesives, cured or dried adhesives, and various adhesives.

Specific examples of these include hot melt adhesives mainly composed of ethylene-vinyl acetate copolymers, synthetic resin solution-type or emulsion-type adhesives, starch glue, synthetic resin adhesives, double-sided adhesive tapes, etc. .

The adhesive layer may be partially applied in any desired shape including dots, lines, and grids.

Further, the thickness is not particularly limited, but it is sufficient if it is 2 rran or less.

Due to this adhesive layer, the bottom of the bottles inside the cardboard box is temporarily adhered to the inner bottom, and it will not move even if there is a slight tilt or vibration.Furthermore, when packaging the cardboard box, the top plate Since the bottles are strongly pressed against the bottom surface, they hardly move even if the packaging cardboard box is overturned.

Therefore, it can be safely transported even without a partition.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing how the cardboard box according to the present invention is used, and FIGS. 2 to 5 are perspective views showing only the inner bottom surface of the cardboard box provided with an adhesive layer. Fig. 2 shows the entire surface, Fig. 3 shows the state in which it is applied in a linear form, Fig. 4 shows it in a grid form, and Fig. 5 shows it in a dotted form.

In the figure, 1 is the cardboard box body, 2 is the inner bottom surface, and 3
is the adhesive layer, and 4 is the bottle.

Next, we will describe the experimental method used to demonstrate the effectiveness of the present invention.

Thickness 5TIr! An adhesive layer as shown in FIGS. 2 to 5 was provided on a 425×318 mm cardboard bottom plate.

On top of that is a 760rr LL capacity glass bottle (height 220rr)
When a bottle full of water was placed in a container (IIn) and one end of the bottom plate was lifted, the angle at which the bottle began to slide was measured.

As shown in the table below, the results are approximately 3 times higher than the untreated one.
I started sliding at more than double the angle.

In other words, it is clear that the bottle will not easily slip even without the top plate of the cardboard box.

Experiment 1 Hot melt adhesive Nilatite HB-195W (manufactured by Nitta Gelatin KK) was applied to 0.2 m + n using a gun type coating machine.
The table below shows the angle at which the bottle starts to slide when it is applied thickly and then cooled.

However, in cases other than those shown in Figure 2, the width is approximately 2.5 mm and the pitch is approximately 15.
7rIM.

Full angle 30 degrees grid 36 degrees linear A*1 37 degrees linear B*235 degrees dotted 45 degrees untreated 11 degrees *1 is applied in the direction parallel to the sliding direction *2 is applied in the direction perpendicular to the sliding direction Coating Experiment 2 A test was conducted in the same manner as in Experiment 1, except that a commercially available emulsion-type vinyl acetate adhesive was coated and dried repeatedly to form an adhesive layer with a thickness of about 0.2TrrIn.

The results are shown in the table below.

Full angle 34 degrees lattice 34 degrees linear A 31 degrees linear 8 31 degrees dotted 35 degrees untreated By providing an adhesive layer on the inner bottom of the cardboard box as shown in 11 degrees or more, bottles become less slippery and cardboard Due to the synergistic effect with the pressure exerted by the box top plate, the bottle does not shift during transportation even without partitions, and can be handled safely without damage.

Therefore, it has the effect of being able to be handled in the same way as conventional products with internal partitions.
