Abstract

An interfold tissue product comprises a tissue stack formed by stacking multiple tissue sheets, wherein each of the tissue sheets is folded in half at least twice, two opposite edges of each tissue sheet created after the first folding are not aligned and form staggered opposite edges, and according to a stacking order of the tissues, the staggered opposite edges (1', 1") of one tissue (1) in each pair of two adjacent tissues and the staggered opposite edges (2', 2") of the other tissue (2) in each pair of adjacent tissues are respectively located at two opposite sides of the tissue stack. Although the thickness of the staggered portions at the opposite edges of each tissue sheet is thinner than that of the remaining portions thereof, such difference in thickness does not accumulate when the tissue sheets are stacked, and the entire tissue stack still has a a uniform thickness, so as to ensure the tissue stack will not tilt to one side, and to guarantee a neat arrangement of the tissues, such that placement of the tissue stack is stable.

Description

Folded paper towel product

Technical field

The present invention relates to paper towel products, in particular to a folded paper towel product which is composed of a plurality of folded paper towels stacked into a stack of paper towels.

Background technique

Folded paper towel products are made up of a stack of paper towels. Each paper towel is folded twice and then interspersed with adjacent upper and lower paper towels. A commercially available folded tissue product, each of which is folded at least twice in half, and the two opposite edges of each first folded of the tissue are not aligned to form staggered opposite sides, and all staggered opposite sides of the tissue are located in the Stack paper towels on the same side. Because the thickness of each folded paper towel is thinner at the opposite side than the other parts, after stacking multiple paper towels, the thickness of the whole stack of paper towels will be significantly uneven, and the thickness at the side where the paper towels are staggered will be obvious. It is smaller than the thickness of the other side opposite to this side, which will cause the stack of paper towels to skew and affect the uniformity of the arrangement of the paper towels, and even make it difficult to place the stack of paper towels smoothly.

technical problem

The purpose of the present invention is to provide a folded paper towel product to overcome the defect that the whole stack of paper towels is skewed due to uneven thickness.

Technical solutions

The present invention is realized as follows: A folded paper towel product includes a stack of paper towels stacked with multiple paper towels. Each paper towel is folded at least twice, and the two opposite edges of each paper towel are folded for the first time. The staggered opposite edges, in the order of stacking of paper towels, in each two adjacent tissues in sequence, the staggered opposite edge of one of the tissues and the staggered opposite edge of the other tissue are respectively located in the stack of tissues Opposite sides.

As a best embodiment, in the first half-fold of each paper towel, the ratio of the width of the narrow portion on one side of the half-fold line to the width of the wide portion on the other side of the half-line is 1/2 to 3 / 4.

Beneficial effect

The advantage of the present invention is that, since the offset opposite sides of each two adjacent paper towels are respectively located on both sides of the stack of tissues, although the thickness of the offset portion of each paper towel is thinner than that of other portions of the paper towel, This thickness difference does not accumulate due to the stacking of paper towels. The thickness of the whole stack of paper towels is still uniform, and the whole stack of paper towels will not skew, ensuring the uniformity of the arrangement of the paper towels, and enabling the whole stack of paper towels to be placed stably.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 is a schematic diagram of stacking paper towels;

Figure 3 is a schematic diagram of the optimal folding ratio of a single paper towel.

Embodiments of the invention

In order to facilitate understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The drawings show a preferred embodiment of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a thorough and comprehensive understanding of the disclosure of the present invention.

The folded paper towel product according to the present invention comprises a stack of paper towels stacked from a plurality of paper towels. Each paper towel passes through two half-folds as shown in Figure 1. The first half-fold uses the dotted line A-A as the double-fold line, and the second half-fold uses the dotted line B-B as the double-fold line. The first half-fold is an asymmetric half-fold. The two opposite edges 1 ', 1' 'are not aligned, forming staggered opposite edges. As a possible implementation manner, each paper towel can also pass through the third, fourth, and other half-folds, and the half-fold line of the next half-fold is perpendicular to the half-fold line of the previous half-fold. Except for the first fold, which is an asymmetric fold, all other folds are symmetric folds.

FIG. 2 shows three paper towels as an example, showing a stacking structure of a stack of paper towels folded from the folded paper towels shown in FIG. 1. As shown in FIG. 2, the offset opposite edges 1 ′, 1 ′ ′ of the paper towel 1 are located on the left side of the stack of paper towels, the offset opposite edges 2 ′, 2 ′ ′ of the paper towel 2 are located on the right side of the stack of paper towels, and the paper towel 3 The staggered opposite edges 3 ', 3' 'are located on the left side of the stack of paper towels, and so on. According to the stacking order of the paper towels, in each of two adjacent paper towels in sequence, the staggered opposite edges of one of the paper towels are The offset opposite sides of another paper towel are located on opposite sides of the stack of paper towels, respectively. In this way, although the thickness of each paper towel at the opposite side is thinner than the other parts of the paper towel, this thickness difference will not be accumulated due to the stacking of the paper towels. The thickness of the whole stack of paper towels is still uniform, and the whole stack of paper towels will not The skewness ensures the neatness of the arrangement of the paper towels, so that the whole stack of paper towels can be placed stably.

In the embodiment shown in FIG. 2, two paper towels adjacent to each other in sequence are inserted into each other. As a possible implementation manner, two adjacent paper towels in sequence may not be interposed, and the paper towel located above is simply placed on the lower paper towel.

As a best embodiment, as shown in FIG. 3, in the first half-fold of each paper towel, the width of the narrow portion on one side of the half-fold line AA is W1, and the width of the wide portion on the other side of the half-fold line AA is The ratio of W2, W1 and W2 W1 / W2 is preferably 1/2 ~ 3/4.

The above-mentioned embodiments only express several implementation manners of the present invention, and their descriptions are more specific and detailed, but they cannot be understood as limiting the scope of the invention patent. For those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. The protection scope of the invention patent shall be subject to the appended claims.
