Description

  The present invention relates to a kitchen towel, and more particularly to a kitchen towel stored in a storage box.

  Conventionally, a roll-type kitchen towel is known (for example, patent document 1). Among them, thick products have a good feeling (strength, water absorption, volume). However, the roll type is inconvenient when collecting (cutting out) a sheet such as when the hand is wet. Therefore, when the box type is stored in a storage box such as tissue paper, there is a problem that the sheet is thick and difficult to bend. Further, there are problems that it becomes difficult to take out the sheets, the sheets are overlapped, and the sheets are stretched.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

  As an example of this embodiment, storage of a kitchen towel will be described. FIG. 1 is a perspective view showing an appearance of a storage box according to the present invention. The kitchen towel package 1 includes a kitchen towel laminate (not shown) in which kitchen towels 3 are laminated, and a substantially rectangular parallelepiped storage having a take-out port 21 in the longitudinal direction of the substantially central portion of the surface of the kitchen towel package 1. It is composed of a box 20. When 1 is used, a finger is inserted into the storage box 20 from the take-out port 21, and the kitchen towel 3 at the top is picked and pulled out. In the case of folding with a rotary cylinder type inter-holder, the kitchen towel removal direction corresponds to the longitudinal direction (MD direction) of the kitchen towel having high tensile strength.

  About the nonwoven fabric which is a base material of a kitchen towel, the thing containing a polypropylene and a pulp fiber is suitable, for example.

  Furthermore, a heat-resistant stabilizer, a lubricant, etc. can be mix | blended with a kitchen towel in the range which does not impair the objective of this invention as needed. Examples of the heat resistant stabilizer include phenol-based stabilizers such as BHT (2,6-di-t-butyl-4-methylphenol).

The basis weight of the kitchen towel is measured by a method according to JIS P8124, preferably 50 g / m ² or more and 130 g / m ² or less, more preferably 60 g / m ² or more and 110 g / m ² or less, and 70 g / m ² or more and 90 g. / M ² or less is more preferable. When it is less than 50 g / m ² , the feeling of use (strength, water absorption, volume feeling) is poor, and conversely, when it exceeds 130 g / m ² , it becomes difficult to bend.

  The paper thickness of the kitchen towel was measured using a thickness gauge (a dial thickness gauge “PEACOCK” manufactured by Ozaki Seisakusho). The measurement conditions were a measurement load of 250 gf, a probe diameter of 30 mm, a sample was placed between the probe and the measurement table, and the gauge when the probe was lowered at a speed of 1 mm or less per second was read. One measurement was performed by stacking 10 samples, and the measurement was repeated 10 times and the measurement results were averaged. The paper thickness is preferably 3.0 mm / 10 or more and 9.0 mm / 10 or less, more preferably 3.7 mm / 10 or more and 7.5 mm / 10 or less, and more preferably 4.5 mm / 10 or more and 6.2 mm / 10 or less is more preferable. When it is less than 3.0 mm / 10 sheets, the feeling of use is poor, and conversely, when it exceeds 9.0 mm / 10 sheets, the ease of folding is lowered.

  The kitchen towels are alternately stacked, folded and stacked by a rotary cylinder type inter-holder, and stored in a storage box having an extraction port on the upper surface. The folding method is not particularly limited, such as a so-called pop-up type or single hold type, in which a part of the next piece is exposed outside the opening when one piece is taken out from the opening during use, but it is taken out with one hand. Easy pop-up format is preferred.

  Although the base material of a storage box is not specifically limited, A paper box, a resin film, a plastic box, and a hand towel dispenser can be mentioned. Further, the size, such as the height, width, and length of the packaging material is not particularly limited. A sticking jig, for example, a magnet, a double-sided tape, or an adhesive, may be attached to a part of the storage box to make it a wall-hanging type.

  The paper box can be formed using, for example, flat paper such as wood pulp, waste paper, corrugated paper, and coated cardboard, and coated cardboard is preferred from the viewpoint of strength.

The basis weight of the flat sheet is measured in accordance with JIS P8124, 250g / ^m is preferably ² or more 550 g / ^{m 2} or less, 300 g / ^m, more preferably ² or more 500 g / ^{m 2} or less, 350 g / ^{m 2} or more 450 g / m ² or less is more preferable. When the basis weight is less than 250 g / m ² , the strength becomes insufficient. On the other hand, when the basis weight exceeds 550 g / m ² , workability decreases when the flat paper is bent and formed into a three-dimensional shape.

  Examples of the resin film at the outlet 21 include a polyethylene film, a polypropylene film, a polyethylene terephthalate film, a polyvinyl alcohol film, a polystyrene film, and an ethylene-vinyl alcohol copolymer film. Of these, a linear low density polyethylene film is preferred because of its high transparency and excellent tearing ability at the perforation. The thickness of the resin film is preferably 40 μm or more and 120 μm or less, more preferably 50 μm or more and 110 μm or less, and further preferably 60 μm or more and 100 μm or less. It is preferable. If it is less than 40 μm, the shape maintaining power of the folded and laminated kitchen towel is low, and the strength of itself is insufficient. On the other hand, when it exceeds 120 μm, the rigidity and the sealability are deteriorated because the rigidity is too high. The thickness of the film was measured using a thickness gauge (a dial thickness gauge “PEACOCK G” manufactured by Ozaki Mfg. Co., Ltd.). The measurement conditions were a measuring force of 1.8 N or less and a measuring element diameter of 10 mm. A sample was set in between, and the gauge when the probe was lowered at a speed of 1 mm or less per second was read. In addition, the measurement was carried out at 10 places and averaged. The ratio of the length (mm) of the cut line of the film at the outlet 21 to the length (mm) of the sheet width is preferably 0.40 to 0.80, more preferably 0.50 to 0.70, 0.55-0.65 is more preferable. If it is less than 0.40, the score line with respect to the sheet width is short, and it may be difficult to take out the sheet. On the other hand, if it exceeds 0.80, the sheet may drop back.

  Here, as an example of the inter holder, a kitchen towel laminate using a rotary cylinder type inter holder and a manufacturing method thereof will be described.

  FIGS. 2A and 2B are explanatory views of the folding machine 100 including a rotary cylinder type inter-holder. The folding machine 100 includes an original roll R and L, a felt roll 31 for knurling and embossing the original web 5 fed from the original roll R and L, a feed roll 32 for passing the sheet 7, And a folding unit 60 that stacks the sheets 7 while being folded.

  The folding unit 60 includes a pair of folding rolls 61 arranged opposite to each other, a knife receiver 62 for cutting the sheet 7 at regular intervals in the traveling direction above the folding roll 61, and a pair of left and right folding bars. 61e and a laminate take-out device 91 for taking out the kitchen towel laminate 9 that is folded and laminated while falling below the folding roll 61.

  FIG. 2B is a diagram showing a state in which the folding roll 61 is rotated 120 degrees in the direction of the arrow from the state shown in FIG.

  As shown in FIGS. 2A and 2B, the folding roll 61 has a vacuum zone 61a at a position equally divided into three in the circumferential direction so that the sheet 7 can be sucked and held. Further, a groove 61c is formed at a position equally divided into three along the circumferential direction of the folding roll 61. A claw-like jaw 61b for gripping a folded portion of the sheet 7 is disposed in the groove 61c, and a position facing the jaw 61b. A knife 61d is disposed on the surface. The jaw 61b rotates in the circumferential direction within the groove 61c, and when the jaw 61b comes into contact with the side wall of the groove 61c, the folded portions of the product sheets 7a and 7b are sandwiched between the jaw 61b. Further, a pair of left and right folding bars 61e for peeling the laminated body folded by the jaws 61b from each folding roll 61 is disposed below each folding roll 61.

  The sheet 7 introduced into the folding unit 60 is cut at regular intervals in the sheet traveling direction by contact between the knife 61d and the knife receiver 62, and is then sucked and held between the left and right folding rolls 61 while being held in the vacuum zone 61a. Move to. For example, when the product sheet 7b held by the jaw 61b of the left folding roll 61 faces the knife 61d of the right folding roll 61, the end of the product sheet 7a held by the right folding roll 61; The folded part of the product sheet 7b is held at the same time. Further, when each folding roll 61 rotates and reaches the folding bar 61e, the folding bar 61e is moved up and down to enter the groove 61c to release the jaw 61b, and the product sheet 7a, 7b is pushed down and folded. The kitchen towel laminate 9 thus formed is sequentially formed. When the number of folded kitchen towel laminates 9 reaches a predetermined number, the laminate take-out device 91 takes them out.

  3A to 3E are enlarged views of the folding unit 60. FIG. The method for folding the kitchen towel laminate 9 using the rotary cylinder type inter-holder will be further described. First, the folded portion of the product sheet 7a is gripped by the claw-shaped jaw 61b on the left folding roll 61, and the product sheet 7b sucked and held in the vacuum zone 61a is held on the right folding roll 61. (FIG. 3A). The left folding bar 61e (not shown) opens the jaw 61b, and the product sheet 7a pushes the folded portion of the product sheet 7a downward while winding the product sheet 7b, so that the fold 71 enters (FIG. 3 (b)). . The right folding bar 61e (not shown) opens the jaw 61b, and the product sheet 7b pushes the folded portion of the product sheet 7b downward while winding the product sheet 7c, so that the fold 71 enters (FIG. 3 (c)). . Similarly, the product sheet 7c is folded 71 while winding the product sheet 7d (FIG. 3 (d)), and the product sheet 7d is folded 71 while winding the product sheet 7e (FIG. 3 (e)). By repeating this, the kitchen towel laminate 9 is formed.

  When folding with a rotary cylinder type inter-holder, the folding direction is a direction perpendicular to the fiber direction (MD direction) 51 of the original web 5, so that a hard sheet is difficult to fold, and a sheet for obtaining good folding performance. Is required to have a suitable softness.

  In addition, the kitchen towel laminated body 9 manufactured by the folding unit 60 is cut into the product length of the kitchen towel by the knife 61d and the knife receiver 62 with respect to the traveling direction of the raw rolls R and L, and then the final set. The kitchen towel laminate 9 is cut into the product width of the kitchen towel (in the direction perpendicular to the folding line) with a cutter (not shown) and then packed in a storage box. .

  As a result of folding as described above, the kitchen towel 3 is stored in the storage box 20 in the manner shown in FIG. Here, the kitchen towel 3 is easily connected to each other by the connecting portions 3a from the normal use state. In FIG. 4, the edge part of the kitchen towel laminated body 9 folded is the connection part 3a. The kitchen towel 3 is embossed, and each sheet is folded so that the surface on which the convex portion is formed and the surface on which the concave portion is formed abut. When folded so that the convex portion and the convex portion or the concave portion and the concave portion are in contact with each other, each sheet becomes slippery, and after one sheet is taken out, the end of the succeeding sheet is taken out of the storage box 20 There is a case where the sheet does not jump out from the mouth 21, or the sheet becomes difficult to be taken out due to slipping or the take-out property is inferior. The embossing shape is preferably a polygonal shape such as a hexagonal shape as shown in FIG. By manipulating this shape and the depth of the emboss, the dynamic friction coefficient can be changed.

FIG. 5 shows a state in which the preceding sheet and the succeeding sheet are connected by three connecting portions 3a. The ratio R (%) of the total length of the connecting portion 3a to the width of the sheet uses the length A (mm) of one connecting portion 3a, the number B (number) of connecting portions, and the width C (mm) of the sheet. It can be obtained by the following formula.
R = {(A × B) / C} × 100 (1)
The ratio R of the total length of the connecting portion 3a to the width of the sheet is preferably 0.0 to 3.5%, more preferably 0.04 to 3.5%, still more preferably 0.1 to 2.0%, Most preferably, an evaluation of take-out property is obtained at 0.2 to 1.4%. If it exceeds 3.5%, it may be difficult to cut the sheet while it is connected, and the take-out property is lowered. Moreover, 0.0-2.2 mm is preferable, as for the length A of the connection part 3a, 0.3-1.6 mm is more preferable, and 0.5-1.2 mm is more preferable. If the length A of the connecting portion 3a exceeds 2.2 mm, it may be difficult to cut while the sheets are connected. The length A of the connecting portion 3a is an average value of the lengths of the connecting portions. Furthermore, the number B of the connecting portions 3a is preferably 0 to 8, more preferably 1 to 8, still more preferably 1 to 4, and most preferably 1 to 2. If the length of the connecting portion 3a is in the above range and the number of connecting portions exceeds 8, the sheet may be difficult to cut while being connected, and the take-out property is deteriorated. Here, when the ratio R is 0.0%, the length A of the joint portion 3a is 0.0 mm, and the number of joint portions is 0, a plurality of sheets are separately provided without providing the joint portions. The separated state is shown.

  FIG. 6A is an enlarged view of the embossing of FIG. 5, and FIG. 6B is a view showing a cross section taken along line AA of FIG. 6A. As described above, the upper surface of the embossed convex portion is formed to be relatively flat, which contributes to improvement in ease of bending, usability, and take-out property.

  Next, the characteristics of the kitchen towel 3 obtained as described above will be described.

First, the specific volume is preferably 4.5 to 10.0 cm ³ / g, more preferably 5.0 to 8.5 cm ³ / g, and even more preferably 5.5 to 7.5 cm ³ / g. Evaluation of ease of use, feeling of use, and takeout is obtained. When it is less than 4.5 cm ³ / g, the ease of bending and the feeling of use are lowered, and when it is more than 10.0 cm ³ / g, the feeling of use and the take-out property are lowered.

  Next, with respect to the dynamic friction coefficient when measured under the following conditions, the first surface on which the convex portion is formed and the second surface on which the concave portion are formed are brought into contact with each other by embossing. Is from 0.62 to 1.14, more preferably from 0.70 to 1.06, and even more preferably from 0.78 to 0.98. If it is less than 0.62, the sheet is slippery and the take-out property is lowered. Conversely, if it exceeds 1.14, the sheet is difficult to slip and the take-out property is lowered. The dynamic friction coefficient was measured using “Automatic Friction Tester NSF-100” manufactured by Nomura Corporation in accordance with ISO 15359. As the value of the dynamic friction coefficient, the measurement was performed three times in one measurement (one sample) and the third value was adopted, and the sample was measured ten times in the MD direction to obtain an average value. Here, the principle of the measurement of the dynamic friction coefficient according to ISO 15359 will be briefly described with reference to FIG. First, when one sample of the kitchen towel 3 is attached to the upper surface of the table 201 of the automatic friction test apparatus 200 and the other sample is attached to the lower surface of the thread 202, and the table 201 is moved, When the frictional force on the contact surface reaches the limit, the sample slips. During the movement of the table 201, the load cell 203 continues to measure the change in pressure from the sled 202 and derives the dynamic friction coefficient based on this data. In addition, when a sample is attached to a table, it will include the crease | fold of a sheet | seat, but even if it measures in the state containing a crease | fold, it does not interfere with a measured value.

  Next, regarding the take-out resistance when taking out the sixth to 25th sheets of the kitchen towel from the take-out opening of the storage box, it is preferably 200 to 650 gf, more preferably 250 to 550 gf, still more preferably 300 to 500 gf. In this case, an evaluation of the take-out property is obtained. If it is less than 200 gf, the sheet may drop back and the take-out property may deteriorate. On the other hand, if it exceeds 650 gf, the resistance increases for taking out the sheet, and the take-out property is lowered. To measure the take-out resistance, fix the center tip of the kitchen towel to the tip of the force gauge gauge and place the kitchen towel vertically from the storage box with the bottom face fixed at a constant speed over a period of 0.4 to 0.6 seconds. The maximum resistance value was measured. A total of 20 kitchen towels were taken from the 6th sheet to the 25th sheet, and the measured values in the force gauge were averaged to determine the removal resistance.

  The dry tensile strength of the kitchen towel is measured with the number of product plies based on the tensile test method of JIS P8113. The dry tensile strength DMDT (Dry Machine Direction Tensile Strength) in the machine direction is preferably 12 N / 25 mm to 35 N / 25 mm, more preferably 15 N / 25 mm to 30 N / 25 mm, and even more preferably 18 N / 25 mm to 25 N / 25 mm. . Moreover, the dry tensile strength in the transverse direction is preferably 5.0 N / 25 mm or more and 15.0 N / 25 mm or less, more preferably 6.5 N / 25 mm or more and 13.0 N / 25 mm or less, as DCDT (Dry Cross Direction Tensile Strength). 8.0 N / 25mm or more and 10.5N / 25mm or less are still more preferable. When dry tensile strength is less than the said range, intensity | strength becomes weak and it becomes easy to tear, and a usability | use_condition may be inferior. On the other hand, when it exceeds the above range, the strength may be increased and it may be difficult to bend.

  Next, regarding the elongation, the length of the sheet stretched until it breaks at the time of the above-described dry tensile strength measurement is shown as a ratio of the length of the sheet before the measurement. In the MD direction, the evaluation of take-out property is obtained preferably at 15 to 45%, more preferably at 20 to 35%. If it is less than 15%, the sheet is difficult to stretch when the sheet is taken out and the take-out property is inferior. On the other hand, if it exceeds 45%, the sheet is excessively stretched when the sheet is taken out. If the CD direction is used, the sheet may be broken when taken out from the storage box. Further, in the case of a material containing polypropylene and pulp fibers as in the present technology, since the elongation in the CD direction is larger than the MD direction, if the take-out direction is the CD direction, the sheet may be stretched too much and the take-out property may be inferior.

  Hereinafter, the present invention will be described more specifically with reference to examples and comparative examples.

Using a nonwoven fabric blended with polypropylene and pulp fibers as a base material for kitchen towels, a kitchen towel having a basis weight of 40.8 g / m ² and a paper thickness of 2.69 mm / 10 sheets was prepared, and each item was measured. The number of connecting portions was one. In Comparative Example 1, the basis weight and paper thickness were set to be smaller than those in Example 1, and the ease of folding was excellent and the take-out property was good. These results are shown in Table 3.

(Comparative Example 2)
Using a nonwoven fabric blended with polypropylene and pulp fibers as a base material for kitchen towels, kitchen towels having a basis weight of 145 g / m ² and a paper thickness of 9.75 mm / 10 sheets were prepared, and each item was measured. The number of connecting portions was one. In Comparative Example 2, the basis weight and the paper thickness were set larger than those in Example 5, and although it was excellent in feeling of use and good in the take-out property, it was remarkably lowered in ease of folding. These results are shown in Table 3.

(Comparative Examples 3-4)
For Comparative Examples 3 and 4, kitchen towels were produced by changing the specific volume based on the same materials as Comparative Examples 2 and 1, respectively, and each item was measured. Note that the number of connecting portions is one. Comparative Example 3 is an example in which embossing is weakened and the specific volume is set smaller than Comparative Example 2, and Example 4 is an example in which embossing is strengthened and the specific volume is set larger than Comparative Example 1. In Comparative Example 3, the feeling in use was lowered, and the ease of bending and the removability were significantly lowered. Although the comparative example 4 was excellent in the ease of bending, it fell in the usability | use_condition and remarkably fell in the extractability. These results are shown in Table 3.

(Comparative Examples 5-6)
About Comparative Examples 5-6, based on the thing substantially equivalent to the comparative example 1, the length and number were changed about the connection part, the kitchen towel was produced, and each item was measured. Comparative Example 5 is an example in which the length of one connecting portion is 0.8 mm, the same number is 11 pieces, and the ratio of the total length of the connecting portions is 4.2%, and Comparative Example 6 is the length of one connecting portion is 3.0 mm. This is an example in which the number is 4 and the ratio of the total length of the connecting portion to the sheet width is 5.7%. About Comparative example 5, although it was excellent in the ease of bending, it took out in the take-out property and it fell remarkably in usability. About Comparative Example 6, although it was excellent in ease of bending, the feeling in use and the removability were remarkably lowered. These results are shown in Table 3.
