Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an embossed paper towel used for eating and drinking, and particularly to improving the emboss arrangement for the purpose of imparting bulk to the embossed paper towel.

PRIOR ART Paper towels are generally known in which multiple sheets of paper are laminated with a thermally adhesive film interposed therebetween, and the entire surface is embossed to increase the bulk and improve the wiping effect.

These are usually impregnated with a sterilizing solution, etc., and then flat-folded in a zigzag or double-folded manner. For example, the flat-folded embossed paper towels are packaged in a roll form or in the same folded form as they are in the flat-folded form, and sold on the market. It is served to.

There are various types of flat-folded embossed paper towels with different emboss shapes and sizes, but they all have the same emboss arrangement, and as shown in Figure 1 A, B, and C, there are many types of flat-folded embossed paper towels. The embossing is arranged in a lattice with a right-slanted array 2 and a left-slanted array 3, and the row spacing W ₁ of the right-slanted array 2 and the row spacing W ₂ of the left-slanted array 3 are made equal intervals, and
The array is arranged so that the tilt angle θ ₁ of the right tilt array 2 and the tilt angle θ ₂ of the left tilt array 3 are equal angles.

Problems to be Solved by the Invention Paper towels are desired to be bulky for their intended use as products, and embossed shaping is also based on this requirement.

However, if the embossments are arranged in a lattice at equal intervals (W ₁ = W ₂ ) and at equal angles (θ ₁ =θ ₂ ) using the right-slant array 2 and the left-slant array 3 as described above, the pattern shown in FIG. 1B As shown in the figure, when this is folded, the embossed peaks 1a of one folded piece and the embossed valleys 1b of the other folded piece overlap, and as a result, it is difficult to obtain a bulky folded state. This causes a problem in that the original effect of embossing is diminished.

As described above, a flat-folded embossed paper towel in which the embossed peaks 1a and troughs 1b overlap on the folded surface has poor elasticity and volume, resulting in a decrease in commercial value.

Means for Solving the Problems As a means for solving the above problems, the present invention provides a paper towel embossed with the lattice arrangement, in which the column spacing of a number of embossments in a right-slanted arrangement and the row spacing of a left-slanted arrangement are different. In addition, by making a difference between the inclination angle of the right-slanted arrangement and the inclination angle of the left-slanted arrangement, interference between peaks is inevitable in a wide overlapping area during flat folding, regardless of the folding position. It is structured so that it can be obtained.

Effects According to the present invention, by making the row spacing and inclination angle of the embossing in a lattice arrangement different between the right-slanted arrangement and the left-slanted arrangement, it is possible to determine at which position the embossing is folded. However, it is possible to always form a state in which the ridges interfere with each other on almost the entire surface of the folding surface.

Therefore, the paper towel can be folded into a sufficiently bulky state regardless of the position of the folding line, and the paper towel can have a rich sense of volume and elasticity, and can increase its commercial value.
Furthermore, the embossing effect can be effectively utilized in a flat folded state without reducing the effect. When this is wound into a spiral roll, the bulkiness is further enhanced and the winding diameter can be increased.

Embodiments Hereinafter, embodiments of the present invention will be described based on Examples A, B, and C of FIG.

As described above, a plurality of sheets of paper are laminated with a heat-adhesive film interposed therebetween, and the entire surface is embossed to have peaks 1a and valleys 1b to form an embossed paper towel.

The embossed paper towel is formed by arranging a large number of embossments in a lattice with a right-slanted arrangement 2 and a left-slanted arrangement 3, as shown in FIG. 2A. In the figure, the intersection of the left inclined array 3 and the right inclined array 2 corresponds to the embossed peaks 1a, and the portion surrounded by the peaks corresponds to the valleys 1b.

In the lattice array, the column spacing of the right-slanted array 2
W ₁ and the column interval W ₂ of the left-tilt array 3 are set so that W ₁ >W ₂ . At the same time, the tilt angle θ ₁ of the right tilt array 2 and the tilt angle θ ₂ of the left tilt array 3 are set so that θ ₂ >θ ₁ .

As described above, the row spacing W ₁ ,
By adopting a configuration that provides a difference in both W ₂ and inclination angles θ 1 _{and θ 2 ,} the emboss arrangement is in a non-parallel state with a deviation angle Z with respect to the fold line 4, as shown in FIG. 2A. The result is an array. Therefore, when this is folded along the fold line 4, a flat folded form is inevitably formed in which the embossed peaks 1a and 1a on the folded surface overlap and interfere, as shown in FIG. 2B, resulting in bulkiness and can do.

The above phenomenon is the same in any flat folding form such as zigzag folding or double folding using the folding line 4, and a similar interference state between peaks is always formed regardless of the position of the folding line.

Therefore, if the paper towel is flat-folded along an arbitrary fold line, an interference state between the embossed peaks is inevitably formed, and an embossed paper towel that is bulky and highly elastic, which is required for the intended use of the product, can be provided.

The spacing between both rows above is the narrow row spacing W ₂ of one of the inclined arrays.
It is preferable to set the other wide row spacing W ₁ to be within the range of "W ₂ ±W ₂ /10" so as to have a difference.

Further, it is preferable that the difference between the two inclination angles is set to be around 5 degrees to around 10 degrees. As a specific example, one inclination angle is around 35 degrees, and the other inclination angle is 40 degrees.

Effects of the Invention As explained above, according to the present invention, by making the row spacing and inclination angle of the embossments arranged in a lattice pattern different between the right-slanted arrangement and the left-slanted arrangement, when the embossments are folded, No matter where the folding line is folded, it is possible to always form a flat folded state in which the ridges interfere with each other on substantially the entire folding surface.

The above-mentioned interference state between peaks during flat folding is obtained as a natural result of the above-mentioned embossed arrangement form, so by flat-folding the embossed paper towel along an arbitrary fold line, it is possible to create a bulky paper towel that always has the above-mentioned interference form. It is possible to form a flat-folded embossed paper towel that has a feeling of elasticity and volume, and to provide a rolled-type embossed paper towel or a folded-type embossed paper towel that has the same effect.

According to the present invention, the embossing effect of the embossing is not diminished in the flat folded state, its effectiveness is increased, the paper towel can be folded into a sufficiently bulky state, and the suitability of the product can be enriched.

Note that the present invention includes embossed paper towels in various forms that involve flat folding, and the product form after flat folding is arbitrary.
