Description

  TECHNICAL FIELD The present invention relates to a tissue paper package in which a laminated body of tissue paper is stored in a film pack.

  Conventionally, a so-called pocket tissue product in which a laminated body of tissue paper is housed in a film pack is known as a tissue product that emphasizes portability (see Patent Document 1). The conventional pocket tissue product has excellent portability, but the number of tissue paper sets stored in one pack is as small as about 10, so that the product is frequently replaced. In recent years, due to an increase in the number of hay fever patients, there is a demand for tissue products that have a larger number of tissue paper sets than pocket tissue products, and are compact and excellent in portability, and are contained in a film pack of approximately the same size as a carton product. It is rising. The film pack tissue has advantages such as high transport efficiency due to its light weight and high compactness, and a small storage space after purchasing the product.

  However, unlike a carton product, a film pack product does not have an upper space, so that it is difficult to take out the tissue when it is first used, and the tissue paper is torn. This tendency is particularly noticeable when the number of tissue groups is large and the capacity is large. Even with a tissue paper package packaged in a conventional film pack, tissue paper having high tissue strength and low paper thickness does not have a problem of tearing the tissue paper. Further, in the case of a soft lotion (also referred to as a moisturizing agent) tissue paper, since the friction with the take-out port of the film is small, the tissue paper is not caught and the take-out property is not a problem.

However, in the case of non-lotion tissue paper, which is soft and has a high paper thickness, unlike the carton product, in addition to being tightly packaged without an upper space, the outlet and the tissue paper Since the friction is high, it is difficult to take out the tissue when it is first used, and the tissue paper is torn.
The present invention has been made in view of the above circumstances, is a tissue paper package that does not contain a moisturizing agent, is soft, and has a high paper thickness stored in a film pack.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same elements are denoted by the same reference symbols throughout the description of the embodiments.

[Tissue paper package]
As shown in FIG. 1, in a tissue paper package 100 of the present invention, a two-ply non-lotion tissue paper 21 (hereinafter sometimes simply referred to as tissue paper) is stored in a film pack 10 in a pop-up type. It will be. Then, as shown in FIG. 2, the non-lotion tissue paper 21 is folded and laminated in a desired number of sets to form the laminated body 20. A perforation portion 11 is formed on the upper surface of the film pack 10, and the perforation portion 11 is cleaved to form a slit-shaped take-out port for taking out the tissue paper 21.
The components of the tissue paper package 100 will be described below.

(Pack density)
The non-lotion tissue paper 21 of the tissue paper package 100 of the present invention has a pack density of 0.11 g / cm ³ or more and 0.22 g / cm ³ or less. Pack density is preferably 0.13 g / cm ³ or more 0.20 g / cm ³ or less, 0.15 g / cm ³ or more 0.18 g / cm ³ or less is more preferable. When the pack density is 0.11 g / cm ³ or more, the compactness is improved, and when the pack density is 0.22 g / cm ³ or less, the non-lotion tissue paper is not torn or feels difficult to take out. Can be taken out.
Here, the "pack density" is a value obtained by the following formula.
Pack density (g / cm ³ ) = mass of non-lotion tissue paper in film pack / volume of film pack

(Average value of take-out resistance)
When the non-lotion tissue paper 21 is taken out from the slit of the film pack 10, the average value of the take-out resistances of the third to fifteenth non-lotion tissue papers is 60 gf or more and 340 gf or less.
When the average value of the take-out resistance is 60 gf or more, the pack density is high and the compactness is excellent. Further, since the average value of the take-out resistance is 340 gf or less, the non-lotion tissue paper 21 does not get caught at the take-out port and is easy to take out.

The method for measuring the take-out resistance is as follows.
From the film pack 10 containing the non-lotion tissue paper 21, gently pull and remove the first two sets of non-lotion tissue paper 21. Next, the third set is set in a Tensilon tensile tester, and while fixing the lower surface, the tissue paper is pulled up at a pulling speed of 1000 mm / min, and the maximum resistance value required until it is pulled out from the film pack is measured. The same measurement is performed for 4 to 15 sets, and the average value of each is taken as the resistance. Take the average value of 5 packs and use as the resistance.

(Tensile strength in ejection direction)
The tensile strength of the non-lotion tissue paper 21 in the take-out direction is 250 gf / 25 mm or more and 460 gf / 25 mm or less. When the tensile strength is 250 gf / 25 mm or more, it can be taken out without breaking during taking out. Further, since the tensile strength is 460 gf / 25 mm or less, softness can be felt. The tensile strength of the non-lotion tissue paper 21 in the take-out direction is preferably 270 gf / 25 mm or more and 410 gf / 25 mm or less, and more preferably 290 gf / 25 mm or more and 350 gf / 25 mm or less.
The tensile strength in the take-out direction is a value measured based on JIS P8113. The tensile strength is measured at a tensile speed of 300 mm / min.

<Non-lotion tissue paper>
The non-lotion tissue paper 21 stored in the present embodiment is composed of a 2-ply sheet, and the base paper is calendered. The non-lotion tissue paper 21 in the present invention means tissue paper which is not coated with a moisturizer, a chemical solution or the like.

As shown in FIG. 2, the folded non-lotion tissue paper 21 constitutes a laminated body 20 by laminating a desired number of sets, and is housed in the film pack 10. The first set of non-lotion tissue papers 21 of the laminated body 20 is half-folded (portion indicated by reference numeral 22) for easy removal.
Here, in the present invention, "half-folding" means, as indicated by reference numeral 22 in FIG. 2, from a state where the tissue paper is folded so that the sheet length becomes about half so that it can be taken out by a pop-up type, This means folding in half.
By folding in half, even if the upper space is small in a tissue paper package having a large capacity, it is possible to easily take out only the first set without accidentally taking out several sets at the top at once. it can. Also, since it is folded in half, the tissue is less likely to tear when taken out.
In FIG. 2, only the first set is half-folded, but the second set may also be half-folded.

The number of sets of the non-lotion tissue paper 21 is more preferably 170 sets or more and 280 sets or less, and further preferably 190 sets or more and 250 sets or less. By adjusting the number of non-lotion tissue papers 21 within the above range, it is possible to reduce the frequency of replacement of the tissue paper package 100 even though it is a compact type. If the number of sets is too large, the height of the film pack becomes high when the paper thickness is constant, and dropback easily occurs when the non-lotion tissue paper in the film pack becomes small.

Further, in the non-lotion tissue paper 21 of the present embodiment, the basis weight per ply is preferably 12 g / m ² or more and 22 g / m ² or less, and 13 g / m ² or more and 20 g / m ² or less. Is more preferable and 14 g / m ² or more and 18 g / m ² or less is further preferable. When the basis weight per ply of the non-lotion tissue paper 21 is 12 g / m ² or more, a volume feeling can be felt, and since the strength is sufficient, tearing at the time of taking out is unlikely to occur. Further, since the basis weight per ply of the non-lotion tissue paper 21 is 22 g / m ² or less, the softness can be felt.

(Paper thickness)
The non-lotion tissue paper 21 has a paper thickness of 0.6 mm / 10 ply or more and 1.3 mm / 10 ply or less. Since the non-lotion tissue paper 21 has a thickness of 0.6 mm / 10 ply or more, the user feels a sense of volume when using a soft tissue paper that is compact and has a large number of sets as in the present application. You can Further, if it exceeds 1.3 mm / 10 plies, dropback occurs when the height of the film pack becomes high and the amount of non-lotion tissue paper in the film pack becomes small when the number of sets is fixed. It will be easier. The paper thickness of the non-lotion tissue paper 21 is more preferably 0.7 mm / 10 ply or more and 1.1 mm / 10 ply or less, and further preferably 0.8 mm / 10 ply or more and 1.0 mm / 10 ply or less. preferable.
The above-mentioned paper thickness indicates the paper thickness when five unfolded 2-ply sheets are stacked.

(GMT)

It is 140 gf / 25 mm or more and 280 gf / 25 mm or less. The GMT is preferably 150 gf / 25 mm or more and 240 gf / 25 mm or less, and more preferably 160 gf / 25 mm or more and 190 gf / 25 mm or less.
When GMT is 140 gf / 25 mm or more, tearing at the time of taking out can be prevented, and when it is 280 gf / 25 mm or less, the user can feel the softness.

(TS7)
The non-lotion tissue paper 21 has a maximum peak intensity TS7 of 6500 Hz, which is automatically acquired by software on a tissue softness measuring device TSA (manufactured by emtec; Tissue Softness Analyzer), having a peak intensity TS7 of 8 dBV ² rms or more and 14 dBV. preferably ² is rms or less, more preferably 9dBV at ² rms or more 13DBV ² rms or less, and more preferably not more than -10 dBV ² rms or more 12DBV ² rms.

When the height CH of the film pack 10 is within the above range, the tissue paper 21 is unlikely to drop back.
By adjusting the length CL of the long side, the length CW of the short side, and the height CH of the film pack 10 within the above ranges, it is possible to realize a large capacity and a compact size and reduce the frequency of replacement. ..

  Each dimension of the film pack 10 in this specification can be measured by the following methods. After placing the facial tissue product 100 on a horizontal surface, a JIS 30 cm ruler (for example, straight scale silver manufactured by Shinwa Measurement Co., Ltd., material stainless steel, 63 g) is placed on the longitudinal direction of the perforated portion 11 of the film pack 10. , The height from the horizontal plane to the ruler at both ends in the horizontal direction of the film pack 10 is measured so as to be parallel to the horizontal direction, and the average value of the two measured values is the height of the film pack 10 ( CH). Next, as the dimension (CL) of the side formed in the lateral direction of the film pack 10, the lateral dimension of the portion where the ruler and the top surface 10a are in contact is adopted. Further, the dimension (CW) of the side formed in the vertical direction of the film pack 10 is arranged at the center of the top surface 10a in the horizontal direction so that the above ruler is perpendicular to the longitudinal direction of the perforated portion 11. The vertical dimension of the portion where the ruler and the top surface 10a are in contact is adopted.

If the thickness of the film is less than 40 μm, the film will be torn during use, and the body in the packaging form will not be formed, and the removability will be poor. On the other hand, when it exceeds 120 μm, the film becomes hard and the film and tissue paper rub against each other at the time of taking out and the tissue paper is broken.

(Perforations and slits)
The film pack 10 has, on the upper surface 10a, a substantially linear perforation portion 11 capable of forming a slit for passing and taking out the non-lotion tissue paper 21 on the upper surface 10a. The perforations 11 are formed substantially parallel to the long side of the upper surface 10a and substantially at the center in the short side direction. The user can form the slit by opening the perforated portion 11, and the non-lotion tissue paper 21 can be taken out through the slit.

(Perforation length)
As shown in FIG. 1, the perforation portion 11 is formed by alternately arranging the cut portions 12 and the non-cut portions 13. It should be noted that both ends of the perforation portion 11 are formed by the notches 12. The longitudinal length PL of the perforated portion 11 is equal to the length of the slit formed by opening the perforated portion 11 in the longitudinal direction. The longitudinal length PL of the perforation portion 11 is preferably 75 mm or more and 150 mm or less, more preferably 85 mm or more and 140 mm or less, and more preferably 95 mm or more in order to improve the take-out property of the non-lotion tissue paper 21. It is more preferably 130 mm or less.

  The length of each cut 12 in the longitudinal direction is 1.5 mm or more and 6.0 mm or less, and the length of each non-cut portion 13 in the longitudinal direction is 0.5 mm or more and 2.0 mm or less.

It is more preferable that the length of each cut 12 in the longitudinal direction is 2.5 mm or more and 4.0 mm or less, and the length of each non-cut portion 13 in the longitudinal direction is 0.8 mm or more 1 More preferably, it is not more than 0.3 mm. Note that the above length is a weighted average value of each notched portion 12 and each non-notched portion 13 of the perforated portion 11.

(Perforation length for tissue paper sheet width)
The length PL of the perforated portion 11 with respect to the sheet width L ₂₁ (see FIG. 1) of the non-lotion tissue paper 21 is preferably 0.4 or more and 0.8 or less, and 0.45 or more and 0.75 or less. It is more preferable that it is 0.50 or more and 0.70 or less.
When the length PL of the perforation portion 11 with respect to the sheet width L ₂₁ of the non-lotion tissue paper 21 is 0.40 or more, the non-lotion tissue paper 21 is easily taken out, and when it is 0.80 or less, the dropback Is less likely to occur.

(Perforation bond rate)
The perforation bond rate of the film is preferably 8% or more and 45% or less, more preferably 12% or more and 35% or less, and further preferably 14% or more and 25% or less. By making the above adjustments, it is possible to secure the required perforation strength during transportation and to maintain a good unsealing property of the film pack 10.
The bond rate of perforations is represented by the following formula.
Non-cutting part ÷ (cutting part + non-cutting part)
(Ratio of the dimension in the longitudinal direction of one non-cutting portion 13 to the total dimension in the longitudinal direction of the set of notching portion and non-cutting portion.)

(Static friction coefficient)
In the present invention, the static friction coefficient measured in the direction in which the back surface of the film constituting the film pack 10 and the non-lotion tissue paper 21 rub against each other when the perforated portion 11 is opened is preferably 0.20 or more and 0.35 or less. , 0.22 or more and 0.33 or less, more preferably 0.24 or more and 0.30 or less.
As will be described later, the folded non-lotion tissue paper 21 has a side formed along the MD direction of the non-lotion tissue paper 21 in the folded state in the longitudinal direction of the perforated portion 11 of the film pack 10. Since they are stacked and stored so as to be substantially parallel to each other, the directions in which the perforations 11 rub against each other when opened are the longitudinal direction of the back surface forming the film pack 10 and the CD direction of the non-lotion tissue paper 21, and the dynamic friction described below is performed. The same is true for the coefficient.

Here, when the perforated portion 11 provided on the tissue paper package 100 is opened, for example, the longitudinal direction of the perforated portion 11 is used as a center line, and the left and right sides of the center line are gripped with respective hands. In the opening direction (the direction substantially orthogonal to the longitudinal direction of the perforation part 11), for example, the left thumb is applied to the left side and the right thumb is applied to the right direction to open the perforation part 11 and slit it. To form. At this time, when the laminated body 20 of the non-lotion tissue paper 21 having a smooth surface as described above is stored in the film pack 10 made of a film having a soft feel and a low elasticity, when pulling in each direction with the thumb while gripping. Since the back surface of the film forming the film pack 10 and the non-lotion tissue paper 21 are slippery, the gripping force is weakened, and the perforated portion 11 tends to be difficult to open.
By adjusting the static friction coefficient measured between the back surface of the film constituting the film pack 10 and the non-lotion tissue paper 21 in the direction in which the perforations 11 rub against each other at the time of opening, the perforations 11 of the perforations 11 are adjusted. The force at the time of opening can be easily transmitted, and it can be made easy to open. Further, if the above-mentioned static friction coefficient is too large, the take-out property tends to deteriorate, but by setting it in the above range, the take-out property of the non-lotion tissue paper 21 is not impaired.

(Dynamic friction coefficient)
The dynamic friction coefficient measured in the direction in which the back surface of the film constituting the film pack 10 and the non-lotion tissue paper 21 rub against each other when the perforated portion 11 is opened is preferably 0.17 or more and 0.27 or less, and 0 It is more preferably 0.18 or more and 0.26 or less, and further preferably 0.20 or more and 0.25 or less. When the dynamic friction coefficient between the back surface of the film pack 10 and the non-lotion tissue paper 21 is within the above range, the non-lotion tissue paper 21 is less likely to be torn when the perforation portion 11 is opened. Further, if the above-mentioned dynamic friction coefficient is too large, the take-out property tends to deteriorate, but by setting it in the above range, the take-out property of the non-lotion tissue paper 21 is not impaired.

  In addition, the static friction coefficient and the dynamic friction coefficient can be measured in accordance with ISO 15359 using "Automatic friction tester NSF-100" manufactured by Nomura Corporation. In ISO 15359, the static friction coefficient and the dynamic friction coefficient are measured three times using the same sample, the static friction coefficient is the first and third values, and the dynamic friction coefficient is the third value. In the present invention, the static friction coefficient and the dynamic friction coefficient are the values of the first time. The tissue paper 21 is provided for measurement in the unfolded state.

  Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments and examples. It will be apparent to those skilled in the art that various modifications and improvements can be added to the above-described embodiment. It is also apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  Hereinafter, the present invention will be described in detail with reference to examples. The present invention is not limited to the examples shown below.
