It is a perspective view which shows the pocket tissue with a fragrance in this embodiment. It is sectional drawing in the pocket tissue II-II line with a fragrance of FIG. It is sectional drawing of the film with a fragrance in this embodiment. It is a figure which shows the process of the cutting | disconnection and insertion of a scented film in this embodiment. The packaging and fusing process in this embodiment are shown, (a) is a plan view, and (b) is a cross-sectional view taken along the line bb of FIG. 5 (a).

Embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.
In the following description, the thickness direction of the pocket tissue 1 is the vertical direction, the short side of the top surface of the pocket tissue 1 is the horizontal direction (short direction), and the direction perpendicular to both the vertical direction and the horizontal direction is the front-back direction. (Longitudinal direction).

<Structure>
For example, as shown in FIG. 1, the pocket tissue 1 of this embodiment is formed in a substantially rectangular parallelepiped shape that is long in the front-rear direction, and a plurality of tissue papers 2 are laminated as shown in FIG. The tissue paper bundle 20, the packaging film 3 for individually packaging the tissue paper 2, and the scented film 4 disposed between the bottom surface of the tissue paper bundle 20 and the packaging film 3 are configured.

  More specifically, the pocket tissue 1 is obtained by packaging a tissue paper bundle 20 in which about 10 to 20 sets of tissue paper 2 folded according to a known folding method are stacked with a resin packaging film 3. There is a flat cushion-like three-dimensional outline composed of a substantially rectangular upper surface 1a and lower surface 1b, and a long side edge 1c and a short side edge 1d connecting them. In general, the length of the short side edge 1d × the length of the long side edge 1c × thickness is 75 ± 10 mm × 125 ± 10 mm × 15 ± 5 mm. The packaging form of the tissue paper bundle 20 by the packaging film 3 may be in accordance with the packaging form of the known pocket tissue 1, and is not particularly limited. In the illustrated example, after the tissue paper bundle 20 is forehead-wrapped with the wrapping film 3, the opening portions at both ends are sealed by a fusion process such as heat sealing (the fusion part is indicated by reference numeral 15). ).

  On the other hand, the pocket tissue 1 of the present embodiment, as with known products, is formed as an outlet forming portion in the direction along the long side edge 1c at the substantially center of the portion facing the upper surface 2a of the tissue paper bundle 20 of the packaging film 3. The perforation line 5 is formed. The internal tissue paper 2 can be taken out from a slit-like outlet formed by tearing the perforation line 5.

  In the illustrated form, according to a known aspect, when the packaging film 3 is framed, the portion where the film edges do not overlap each other is configured to face the upper surface 2a of the tissue paper bundle 20, but in this form It is not limited.

  In the pocket tissue 1, a scented film 4 is interposed between the packaging film 3 and the bottom surface of the tissue paper bundle 20, and a fragrance is mixed in the scented film 4. When the fragrance of the scented film 4 is volatilized, it is released into the space wrapped with the packaging film 3 and the scent is imparted to the tissue paper bundle 20.

The tissue paper 2 has a ply structure in which two to three thin papers are laminated.
The raw pulp of the thin paper is a mixture of NBKP and LBKP, and may be appropriately combined with waste paper pulp. However, in terms of texture and the like, it is preferably composed only of NBKP and LBKP. In this case, the blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

The rice tsubo per thin paper constituting each ply of the tissue paper 2 according to the present invention is preferably 9 to 25 g / m ² , more preferably 10 to 15 g / m ² . If the rice tsubo is less than 9 g / m ² , it is preferable from the viewpoint of improving softness, but it is difficult to ensure adequate strength that can withstand use. On the other hand, if the rice tsubo exceeds 25 g / m ² , the entire paper becomes hard and a feeling of stickiness is generated, resulting in poor touch. In addition, the US tsubo is based on the US tsubo measurement method of JIS P 8124 (1998).

  The paper thickness of the tissue paper 2 according to the present invention is preferably 100 to 160 μm, more preferably 120 to 140 μm in the ply state. If the paper thickness is less than 100 μm, it is preferable from the viewpoint of improving softness, but it is difficult to ensure the strength as the tissue paper 2 properly. On the other hand, if it exceeds 160 μm, the texture of the tissue paper 2 is deteriorated, and a feeling of tingling is generated during use.

  The paper thickness of tissue paper 2 was measured by thoroughly adjusting the specimen under the conditions of JIS P 8111 (1998), and then dial thickness gauge (thickness measuring instrument) “PEACOCKG type” (Ozaki) under the same conditions. (Made by Seisakusho). Specifically, confirm that there is no dust, dust, etc. between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to adjust the zero point, and then Raise the plunger, place the sample on the test bench, slowly lower the plunger and read the gauge at that time. At this time, only the plunger is placed. The terminal of the plunger is made of metal and a circular plane having a diameter of 10 mm is perpendicular to the plane of the paper. The load at the time of measuring the thickness is about 70 gf at 120 μm. The thickness is an average value obtained by performing measurement 10 times.

  The packaging film 3 is not particularly limited in the present invention, and a known film can be used. As a specific example, it is formed of a film made of a thermoplastic resin such as a polyethylene film or a polypropylene film having a thickness of 20 to 100 μm. The thickness is measured in the same manner as the thickness of the tissue paper 2 described above. However, this is done with one film.

  As shown in FIG. 3, the scented film 4 includes a fragrance-permeable film layer 41 and a fragrance-impermeable film layer 42, and an intermediate layer 43 made of an adhesive or a pressure-sensitive adhesive that is interposed between them and adheres both films. In particular, a fragrance is contained in the intermediate layer 43, and the fragrance is volatilized through the fragrance permeable film layer 41. Therefore, in the packaging film 3, the fragrance volatilized from the scented film 4 is diffused, and the fragrance is transferred to the tissue paper bundle 20, whereby the tissue paper 2 is given fragrance. For this reason, compared with what apply | coats a fragrance | flavor directly to the tissue paper 2, a fragrance will be felt for a long time.

  Here, the scented film 4 according to the present invention has a fragrance-permeable film layer 41 on one side and a fragrance-impermeable film layer 42 on the other side. It is because the fragrance | flavor contained in the intermediate | middle layer 43 comes to be volatilized outside effectively rather than doing. Moreover, while volatilizing such an effective fragrance | flavor to the exterior is promoted, especially the fragrance | flavor permeable film layer 41 side faces the tissue paper bundle 20, and the fragrance | flavor impermeable film layer 42 side faces the packaging film 3. This is because the aroma is easily transferred to the tissue paper 2 by arranging in this manner. In particular, as described above, the packaging film 3 is generally a polypropylene film or a polyethylene film, and these films have relatively high gas permeability. By arranging the fragrant film 4 so that the fragrance-impermeable film layer 42 faces the packaging film 3, the fragrance does not easily leak out of the packaging film 3.

  Specific thicknesses of the fragrance-permeable film layer 41 and the fragrance-impermeable film layer 42 are 10 to 60 μm. Within this range, the fragrance-permeable film layer 41 can transmit the fragrance, while the fragrance-impermeable film layer 42 does not transmit the fragrance by the aluminum vapor deposition treatment or the transparent vapor deposition treatment. can do.

As for the specific gas barrier properties of the perfume permeable film layer 41, the oxygen permeability is preferably 700 cc / m ² · 24 h · atm or more. With this oxygen permeability, the perfume is permeated. If it is the above-mentioned polypropylene film layer and a polyethylene film layer, it can be set as this oxygen permeability. In addition, if the carbon dioxide gas permeability is 4000 cc / m ² · 24 h · atm or more, the types of perfume that can be permeated can be increased, and variations in aroma can be increased. Oxygen permeability and carbon dioxide gas permeability are measured according to the JIS K 7129-2 (2006) plastic film and sheet gas permeability test measurement method.

The specific gas barrier property of the perfume impermeable film layer 42 is preferably such that the oxygen permeability is less than 200 cc / m ² · 24 h · atm. With this oxygen permeability, permeation of the fragrance can be effectively suppressed. In addition, the carbon dioxide gas permeability is preferably less than 900 cc / m ² · 24 h · atm.

  The difference in thermal shrinkage between the fragrance-permeable film layer 41 and the fragrance-impermeable film layer 42 is preferably 0.2 or less. In this way, the curl size is kept to 10 mm or less.

Examples of the adhesive and pressure-sensitive adhesive for forming the intermediate layer 43 include polyester-based adhesives, latex-based pressure-sensitive adhesives, hot-melt adhesives, and acrylic pressure-sensitive adhesives. Polyester adhesives and acrylic pressure-sensitive adhesives are preferable. The thickness of the intermediate layer 43 is desirably 5 to 80 μm, and more desirably 15 to 35 μm. If it is the exemplified adhesive and pressure-sensitive adhesive, and further within the thickness range, each film layer can be securely bonded, and a perfume can be sufficiently contained. The blending ratio of the fragrance in the intermediate layer 43 can be appropriately designed depending on the concentration and type of the fragrance, but is preferably 0.5 to 15 g / m ² , more preferably 0.5 to 6 g / m ² . If it is this range, it can be set as the intensity | strength of moderate fragrance.

  The fragrance | flavor contained in the intermediate | middle layer 43 can be selected suitably. Specific examples include Ryuzen Incense, Benzo Incense, Sea Aroma Incense, Spirit Cat Incense, Ding Oil, Galvanam, Jasmine Absolute, Labanam, Mate Tea, Merilot, Mimosa, Musk Tonkin, Myrrh, Oak Moss or Moss de Chine, Milk Incense, Bikushi Incense, Oris, Bachuri , Rosemary oil, sandalwood oil, vetiver oil, natural fragrance such as violet leaf absolute, higher alcohol, aldehyde, benzaldehyde, benzoic acid, cinnamic acid, cinnamic aldehyde, cinnamic alcohol, coumarin, ester, indole, ketone, salicylic acid And various synthetic fragrances such as terpenoids and vanillin or a mixture of two or more of these. Commercial products can also be used.

<Scented pocket tissue manufacturing device and manufacturing method>
As shown in FIG.4 and FIG.5, the pocket tissue manufacturing apparatus 100 with a fragrance cut | disconnects the film 40 with the fragrance wound by roll shape to predetermined length with the cutter roll 8, and on the vacuum roll 6, The curl of the scented film 4 is moved while being pressed, inserted into the bottom surface of the tissue paper bundle 20 conveyed by the belt conveyors 9a and 9b, and the tissue paper bundle 20 and the scented film 4 containing the fragrance are individually separated by the packaging film 3. It is an apparatus for packaging and producing a pocket tissue 1.

  Specifically, as shown in FIGS. 4 and 5, the scented pocket tissue manufacturing apparatus 100 is composed of a vacuum roll 6 that transports the scented film 40 with the roll-like scented film 40 adsorbed thereon, and a vacuum roll 6. A roll 7 having a scented film 40 nip and a roll 7 having a scented film 40 positioned downstream of the transport roll 7 and adsorbed to the vacuum roll 6. Cutter roll 8 that cuts 40 in the width direction by a predetermined length, belt conveyors 9a and 9b that convey the tissue paper bundle 20, tissue paper bundle 20 that has moved the belt conveyor 9b, and the cut fragrant film 4 The packaging film 3 in the vicinity of the front and rear ends of the tissue paper bundle 20. A fusing unit 18, and a.

The vacuum roll 6 has a double structure of an inner fixed roll 61 and an outer movable roll 62. The movable roll 62 rotates and the fixed roll 61 does not rotate. The fixed roll 61 can suck air inside or discharge air outside using a pump (not shown) depending on the location in the circumferential direction. That is, air is sucked in the vicinity of the cutter roll 8 (portion indicated by “−” in FIG. 4), and air is discharged in the vicinity of the belt conveyor 9b (portion indicated by “+” in FIG. 4).
Moreover, the center of the vacuum roll 6 and the center of the film 40 with a roll-like fragrance overlap with the up-down direction. Thereby, even if the winding length of the film 40 with a roll-like fragrance changes, the change of the tension | tensile_strength concerning the film 40 with a roll-like fragrance can be decreased.

  Further, between the vacuum roll 6 and the belt conveyor 9b, a guide 10 for guiding the scented film 4 to be reliably transferred from the vacuum roll 6 to the belt conveyor 9b, and the guide 10 guides the film. A pressing roll 11 is disposed that sandwiches and conveys the scented film 4 with the belt conveyor 9b.

  And the scented film 4 cut | disconnected by the cutter roll 8 from the roll-like scented film 40 is conveyed in the state closely_contact | adhered to the vacuum roll 6, and vacuum is cancelled | released in the position approaching the belt conveyor 9b, and air discharge | releases. As a result, it leaves the vacuum roll 6 and passes through the guide 10. The scented film 4 that has passed through the guide 10 is transferred to the belt conveyor 9b while being sandwiched between the pressing roll 11 and the belt conveyor 9b. At the same time, the tissue paper bundle 20 is transferred from the belt conveyor 9a to the belt conveyor 9b. Inserted into the bottom.

  As shown in FIGS. 5 (a) and 5 (b), the wrapping portion 17 is formed into a rectangular tube shape through the rectangular tube guide 17a so that the perforated line 16 formed in advance is directed upward. The tissue paper bundle 20 and the scented film 4 that have moved on the belt conveyor 9b are wrapped.

  The fusing part 18 has a thermocompression bonding part (not shown) that seals the packaging film 3 by thermocompression bonding and a cut part (not shown) that cuts the thermocompression bonded part along the width direction. When the tissue paper bundle 20 and the scented film 4 pass through the fusing position in a state of being wrapped in the packaging film 3 through 17a, the opening is sealed by fusing the packaging film 3. The sealed portion is cut in the width direction at the center in the longitudinal direction. As a result, one pocket tissue 1 is completed, and at the same time, the front opening of the next pocket tissue 1 is sealed. By repeating these steps, the pocket tissue 1 can be manufactured one after another.

Next, the curl amount and the operation loss rate were compared between the method for manufacturing the pocket tissue 1 of the present invention (Example) and the method for manufacturing the conventional pocket tissue 1 (Comparative Example).
In the embodiment, as described above, the scented film 4 cut by the cutter roll 8 from the roll-like scented film 40 is conveyed in a state of being in close contact with the vacuum roll 6 and is vacuumed at a position approaching the belt conveyor 9b. It is released and air is released, so that it leaves the vacuum roll 6 and passes through the guide 10. The scented film 4 that has passed through the guide 10 is transferred to the belt conveyor 9b while being sandwiched between the pressing roll 11 and the belt conveyor 9b, and at the same time, the tissue paper bundle 20 is transferred from the belt conveyor 9a to the belt conveyor 9b. Inserted into the bottom.
In the comparative example, the cut scented film is inserted into the bottom surface of the tissue paper bundle 20 one by one using an insertion machine. More specifically, when the tissue paper bundle 20 conveyed from the upstream is transferred to the belt conveyor, the scented film cut in advance is inserted between the tissue paper bundle 20 and the belt conveyor.
As the scented film, a two-layer film of a CPP film as a fragrance-permeable film layer and a PET film as a fragrance-impermeable film layer was used.
The characteristics of the scented film are as shown in Table 1.

ここで、熱収縮率の測定は次の（１）〜（７）のように行なう。（１）まず、フィルムシートを２０×１００ｍｍの四角形に裁断して試料とする。（２）試料は、長辺がＭＤ方向（縦方向）に沿うものと、長辺がＣＤ方向（横方向）に沿うものとを、それぞれ５本ずつ用意する。（３）各試料の幅方向（短辺に沿う方向）中央に長辺と平行な目視可能な直線を長辺方向の全長に渡って、適宜の筆記具により付する。（４）各試料を２３℃、５０％ＲＨにて２時間以上十分に調湿した後、前記直線の長さを測定して試料の寸法Ａとする。（５）各試料を、フィルムシートの素材に応じた適宜の温度及び時間に設定した恒温恒湿槽に保管する。湿度は５０％ＲＨとする。（６）設定時間後の試料の直線の長さを測定して試料の寸法Ｂとする。（７）熱収縮率（％）＝（（（寸法Ｂ）−（寸法Ａ））/（寸法Ａ））×１００の式に当てはめて熱収縮率を算出した。

Here, the measurement of the thermal contraction rate is performed as in the following (1) to (7). (1) First, a film sheet is cut into a square of 20 × 100 mm to obtain a sample. (2) Prepare five samples each having a long side along the MD direction (longitudinal direction) and one with a long side along the CD direction (horizontal direction). (3) A visible straight line parallel to the long side is attached to the center in the width direction (direction along the short side) of each sample over the entire length in the long side direction with an appropriate writing instrument. (4) Each sample is sufficiently conditioned at 23 ° C. and 50% RH for 2 hours or more, and then the length of the straight line is measured to obtain the dimension A of the sample. (5) Each sample is stored in a constant temperature and humidity chamber set to an appropriate temperature and time according to the material of the film sheet. The humidity is 50% RH. (6) The length of the straight line of the sample after the set time is measured and set as the dimension B of the sample. (7) Thermal contraction rate (%) = ((Dimension B) − (Dimension A)) / (Dimension A)) × 100 was applied to calculate the thermal contraction rate.

Further, the curl amount of the scented film was measured.
The curl amount is measured by adjusting the size of the scented film in the MD direction (vertical direction) 80 mm × CD direction (transverse direction) 100 mm, and adjusting the humidity at 23 ° C. and 50% RH for 2 hours. Under the same environment, the fragrance-impermeable film is placed on the horizontal table with the fragrance-impermeable film on top and the fragrance-permeable film on the bottom. At that time, the distance (average of 4 points) between the corner of the film curled into a U shape or an inverted U shape on the horizontal table and the horizontal table was measured. As a result, the curl amount of 10 samples in the scented film was 8 to 20 mm, and the average was 12 mm.

(Evaluation)
In the above-described examples and comparative examples, 1000 pocket tissues were manufactured, and the operation loss rate (%) was evaluated.
The operation loss rate is the number of defective products / pocket tissue manufactured products (1000 pieces) × 100 (%) due to poor insertion of the scented film.
And the operation loss rate of an Example is 0.095-0.1 when the operation loss rate of a comparative example is set to 1, and the operation loss rate was improved to about 1/10 of the comparative example.
In particular, even when the curl amount was 20 mm, the operation was stable without any influence.

  As described above, according to the manufacturing method of the pocket tissue 1, the roll-like scented film 40 is cut by the cutter roll 8, and the cut scented film 4 moves while being adsorbed on the vacuum roll 6. When the tissue paper bundle 20 of the tissue paper 2 that has moved on the belt conveyor 9a reaches the belt conveyor 9b, the vacuum is released and air is released, and the tissue paper bundle 20 is inserted into the bottom surface of the tissue paper bundle 20 to be inserted. 20 and the scented film 4 are individually packaged to produce the pocket tissue 1. Since the scented film 4 is inserted into the bottom surface of the tissue paper bundle 20 immediately after cutting the roll-like scented film 40, curling of the scented film 4 can be prevented and the problem of poor insertion can be solved. it can.

  Since the scented film 4 moves while being vacuumed on the vacuum roll 6, it is possible to prevent curling due to room temperature and the like, and also prevent falling from the belt conveyor 9b. Therefore, it has the advantage of a scented film that moderately controls the strength of the scent and has excellent scent sustainability, and can stably insert the scented film into the bottom of the tissue paper bundle. it can.

In particular, the scented film 4 has a layer structure of the fragrance-permeable film layer 41 and the fragrance-impermeable film layer 42, so that it is more easily curled. it can.
In addition, since the cut scented films are inserted one by one using an insertion machine, the film needs to be firm. For this reason, although the thickness of the scented film was set to about 100 μm, if it is inserted under the tissue paper bundle by the present method, it can be made thin if the scent can be maintained (perfume permeation). Film layer 41: preferably 20-80 μm, more preferably 20-50 μm, and perfume impermeable film layer 42: preferably 10-60 μm, more preferably 10-30 μm.

  In addition, the scented film 4 is adsorbed on the vacuum roll 6 until it reaches the belt conveyor 9b, and when the scented film 4 is transferred to the belt conveyor 9b, air is released to separate the scented film 4 from the vacuum roll 6. The film 4 can be reliably conveyed from the vacuum roll 6 to the belt conveyor 9b.

  Furthermore, the scented film 4 is passed through the guide 10 between the vacuum roll 6 and the belt conveyor 9b, and the scented film that has passed through the guide 10 is conveyed by being sandwiched between the belt conveyor 9b and the pressing roll 11. The scented film 4 can be reliably inserted into the bottom surface of the tissue paper bundle 20 placed on the belt conveyor 9b.

  According to this embodiment, since the insertion failure of the scented film 4 can be prevented, the size of the scented film 4 to be cut is not particularly limited as long as it is smaller than the width of the rectangular tube guide 17a.

  The length of the scented film 4 in the longitudinal direction may be the same as the length of the tissue paper bundle 20, or may be longer or shorter. In the case of being long, the packaging film 3 and the scented film 4 may be melted simultaneously after individual packaging with the packaging film 3. However, the length is within the range of a known pocket tissue.

  Moreover, since the scented film 4 has high manufacturing cost, you may make it small size. By changing the size, the sustainability and strength of the scent can be adjusted. By reducing the speed of the vacuum roll 6 according to the size of the scented film 4, the scented film 4 can be reliably disposed on the bottom surface of the tissue paper bundle 20. The speed of the belt conveyors 9a and 9b is preferably 7 to 20 m / min. When the speed of the belt conveyors 9a and 9b is 10 m / min, the speed of the vacuum roll 6 is preferably 4 to 9 m / min.
