Description

  The present invention relates to a pocket tissue product. More specifically, the present invention relates to a pocket tissue product that is excellent in design and ease of taking out the product, and excellent in storage during use.

  In general pocket tissue products, tissue paper is folded into a rectangle or a square and appropriately stacked, and then wrapped with a plastic film such as polyethylene, polypropylene, polyvinyl chloride, polyester, or polyvinyl alcohol.

FIG. 5 is a schematic view of a conventional pocket tissue product. In FIG. 5, the wrapping film 2 encloses the tissue paper 1 appropriately folded according to the size of the product, and in many cases, the end of the film 2 is thermally bonded, and the adhesive portion 3 is centered on the upper surface thereof. In other words, the perforation 4 is provided in parallel to the long side. The consumer will tear the perforation 4 and remove the tissue paper on the first use. (For example, refer to Patent Document 1.)
JP 9-313393 A

  When the perforation 4 is opened to take out tissue paper from the pocket tissue product as described above, there is a problem that the tissue paper is torn. In particular, in the case of tissue papers excellent in touch feeling such as so-called lotion tissue paper and moisturizing tissue paper, this tendency becomes remarkable.

  One of the factors that cause the tissue paper to break is that the paper strength of the tissue paper is too weak. The paper strength of the tissue paper is a problem in the direction of tearing the perforation 4, and if it is too weak, it may be increased. However, the paper strength of the tissue paper correlates with softness and touch feeling, which are important quality items. There is a need to maintain a certain paper strength for quality control, and it is not easy to change. Another method is to change the paper folding method so that the orientation of the paper is oriented at right angles to the perforation, but it is very difficult to design the manufacturing equipment and is actually effective. I can't say that.

  An object of the present invention is to solve the problem that tissue paper is easily broken when tearing a perforation to take out the tissue paper, which is a problem in so-called pocket tissue products.

  As a result of intensive studies in view of the above, the present inventors have found that this problem can be solved by devising the shape of the perforation, and have completed the present invention.

  That is, the pocket tissue product according to the present invention is obtained by folding tissue paper into rectangles or squares, wrapping them appropriately, packaging the film, providing a perforation on the upper surface, and tearing the perforation. In the pocket tissue product forming the outlet, the perforation has an angle of 10 to 80 degrees with respect to the long side, and the tissue paper outlet is formed by breaking the perforation, the perforation opening The width of the part is in the range of 1/3 to 4/5 with respect to the length of the diagonal line.

  In the present invention, preferably, the tissue paper to be included is lotion tissue paper.

  The pocket tissue product according to the present invention is of great practical value because it is less likely to break together the tissue tissue when tearing the perforation to first remove the tissue paper. In addition, the hygienic function that protects tissue paper from dust and dust by film wrapping and the storage stability when carrying can be maintained at the same level as before, and the degree of freedom of design can be increased by moving the perforation position. Can be spread.

  Hereinafter, the pocket tissue product of the present invention will be described in detail.

  FIG. 5 is an overall schematic view of a conventional pocket tissue product. First, the main points of the present invention will be described with reference to this drawing.

  In general, in the case of a conventional product, in FIG. 5, the packaging film 2 includes a tissue paper 1 that is appropriately folded according to the size of the product, and a perforation 4 is provided in the center of the upper surface in parallel with the long side. It has been. The folding direction of the tissue paper 1 is the folding machine, so that the long side is the paper machine flow direction and the short side is the paper machine width direction. When tearing, the tissue paper 1 receives a force in the width direction in which the paper strength is relatively weak. As a result, tissue paper that is excellent in touch feeling such as lotion tissue paper and has relatively weak paper quality is a major cause of paper breakage when the perforation 4 is torn.

  Accordingly, in the present invention, the paper breaks are reduced by providing the perforation 4 with an angle of 10 to 80 degrees with respect to the long side. In addition, although the method of changing the folding direction of tissue paper and making the long side into the width direction of a paper machine is also considered, it cannot be said realistic because it is necessary to change the existing mechanical equipment largely.

  Examples of the shape of the tissue paper outlet of the present invention are shown in FIGS. These are examples of the present invention, and the present invention is not limited to these.

  FIG. 2 is an example in which the perforation serving as the tissue paper outlet is provided on the diagonal line of the product. In this example, if the long side is 106 mm and the short side is 97 mm, the perforation is provided at an angle of about 42 degrees with respect to the long side, and the force applied in the width direction of the paper when tearing the perforation is This can be reduced to about 70% when the perforations are provided in parallel.

  If the perforation length is too short, the resistance when pulling out the internal tissue paper will increase and cause the tissue paper to tear.If it is too long, the packaging film will be torn or the tissue paper being used will be unintentionally popped out. Since it also causes, there is a preferable range, and the required length is preferably in the range of 1/3 to 4/5 of the diagonal line.

  2 and 3 are examples in which the perforation is shifted from the diagonal line. By shifting the perforation from the diagonal as in this example, the area of the continuous portion of the upper surface can be changed. As a result, for example, the design options of the character can be increased without being cut at the perforations.

  In the present invention, the packaging film to be used is not particularly different from conventionally used materials, and plastic films such as polyethylene, polypropylene, polyvinyl chloride, polyester, and polyvinyl alcohol can be used.

  Hereinafter, the present invention will be specifically described with reference to examples. However, the present invention is not limited to these examples. In Examples and Comparative Examples, the following tissue papers and packaging films were used and tested by the following test methods.

(1) Tissue paper As tissue paper, ^two lotion tissue papers with a basis weight of 15.0 g / m ² are stacked, and the longitudinal direction is the paper machine flow direction and the short side direction is the width direction, just like the actual machine. , The long dimension was 205 mm, the short dimension was 197 mm, and 20 sets were folded to have a long side of 106 mm and a short side of 97 mm as shown in FIG. At this time, the length of the diagonal line of the folded tissue paper is about 145 mm, and the angle formed between the paper flow direction (long side) and the diagonal line is about 42 degrees. Further, the paper flow direction is the direction of the arrow illustrated in FIG.

(2) Packaging film As a packaging film, a polyethylene film having a thickness of 40 μm was used. When a perforation is provided from the center of the short side of the film in parallel to the long side and packaged, and both ends of the short side are thermally bonded, the state shown in FIG. 5 is obtained.

<Test method>
(1) After 20 sets of tissue papers were wrapped on the above-mentioned packaging film, the perforation was broken, and the tearing conditions of the lower tissue papers were compared at that time. The test was conducted with 10 monitors, and the situation of multiple times was evaluated in five stages: ◎ (very good), ○, =, Δ, × (bad).

(2) Tissue paper was pulled out from the test sample in a state in which the perforation was broken, and the removal state at that time was evaluated in five stages: ◎ (very good), ○, =, Δ, × (bad).

(3) Have the test sample with the perforation broken in the same way as normal usage, and the storage status at that time is ◎ (very good), ○, =, △, × (bad) It was evaluated with.
