A film package comprising a temporary binding portion is disclosed. In this film package, the temporary binding portion is formed by perforations.

JP, 2016-188092, A

  However, in the film package disclosed in Patent Document 1, there is a problem that the upper surface of the packaging bag does not tear along the perforations and the takeout port is broken (see FIG. 7, symbol B). In addition, it is possible to make the takeout opening easy to tear along the perforation by decreasing the perforation pitch, etc., but there is a possibility that the perforation may be broken during the production or transportation of the package, resulting in product failure. .

  An object of the present invention is to provide a tissue paper package in which the take-out portion is not easily damaged at the time of opening.

  In order to solve the above problems, according to a first aspect of the present invention, there is provided a packaging bag formed of a flexible first film for containing a thin paper, and the above-mentioned thin paper formed on the upper surface of the packaging bag. A thin paper paper package having a takeout portion for taking out, which is formed of a flexible second film and formed on a sheet laminated on the top surface of the packing bag, the top surface of the packing bag and the sheet, The sheet and the upper surface of the packaging bag have a cutout penetrating in the thickness direction, and the cutout is broken to form the extraction part on the upper surface of the packaging bag and the sheet. Provide a paper paper package.

  In the first aspect, the sheet formed of the flexible second film is laminated on the upper surface of the packaging bag formed of the flexible first film, and the upper surface of the packaging bag and the sheet in the thickness direction A penetrating incision is formed. Therefore, the periphery of the takeout portion formed by breaking the cut portion has a two-layer structure in which the first film and the second film are laminated.

  In the first aspect, by forming the periphery of the extraction portion with such a two-layer structure, the strength around the extraction portion can be increased. Thereby, when the cut portion is broken, it is possible to prevent the periphery of the take-out portion from being cut or torn. Therefore, in the first aspect, it is possible to suppress breakage of the takeout portion at the time of opening.

  In the first aspect, as described above, the strength of the periphery of the take-out portion is increased to prevent the periphery of the take-out portion from being cut or torn even when taking out thin paper from the take-out portion. it can. Therefore, in the first aspect, breakage of the take-out portion can be prevented even at the time of use after opening (see FIG. 6).

  Furthermore, in the first aspect, as described above, since it is difficult for the takeout portion to be broken when the thin paper package is opened, it is necessary to make the cut portion easy to break in advance by reducing the pitch of the cut portion. Absent. Therefore, as described above, the strength around the take-out portion can be increased, so that product defects due to breakage of the cut portion caused by breakage of the cut portion during manufacture of the thin paper package or during transportation before opening can be prevented. it can.

  The second aspect provides a thin paper package in which the first film and the second film are made of different materials.

In the third aspect, the sheet is laminated on the upper surface of the packaging bag so that the orientation direction of the first film and the orientation direction of the second film intersect. In such a configuration, when the cut portion is broken, a force of attraction between the two films can intersect in the planar direction of the laminated surface of the upper surface of the packaging bag and the sheet.

  Thereby, in the third aspect, when the cut portion is broken, a force of attraction between the two films can be reliably obtained in the surface direction of the laminated surface of the upper surface of the packaging bag and the sheet. Then, the packaging bag and the sheet are more likely to be broken alternately. As a result, the force for breaking the incised portion can be more easily transmitted along the incised portion, so that it is possible to reliably prevent the periphery of the takeout portion from being broken or torn. Therefore, in the third aspect, it is possible to further suppress breakage of the takeout portion at the time of opening.

  In a fourth aspect, the orientation direction of the first film is a direction along the longitudinal direction of the cut portion, and the orientation direction of the second film is a direction orthogonal to the orientation direction of the first film , Provide a paper package. In the fourth aspect, the sheet is laminated on the packaging bag such that the orientation directions of the first film and the second film are orthogonal to each other.

  With such a configuration, in the fourth aspect, when breaking the cut portion, the force to break in the direction orthogonal to the direction along the cut portion (outward direction of the take-out portion) Thus, a force is generated that pulls one of the films in the direction in which the other film follows the incision. Therefore, in the vicinity of the cut portion, the packaging bag and the sheet are easily broken alternately. As a result, the force for breaking the incised portion can be reliably transmitted along the incised portion, so that it is possible to reliably prevent the periphery of the takeout portion from being broken or torn. Therefore, in the fourth aspect, it is possible to further suppress breakage of the takeout portion at the time of opening.

  According to a fifth aspect, there is provided a paper product comprising the paper packaged in a paper package according to any of the first to fourth aspects. In the fifth aspect, since the thin paper product is configured using the tissue paper package of any of the first to fourth aspects, the same function and effect as those of the first to fourth aspects A tissue paper product can be provided.

  A sixth aspect is a method for producing a thin paper product comprising the take-out portion for taking out the thin paper, and the take-out portion containing the thin paper in a thin paper package formed by breaking the cut portion, A first step of laminating a flexible second film on a flexible first film, the first film and the second film, and the first film and the second film in the thickness direction A second step of forming the incised portion penetrating to the second, a third step of storing the thin paper in a packaging bag in which the first film is folded, and a fourth step of sealing the packaging bag containing the thin paper The present invention provides a method of producing a thin paper product having:

In addition, the shape of the packaging bag 10 is not limited to the shape of this embodiment, It has another three-dimensional shape according to the shape of the laminated body of the thin paper T and the thin paper T accommodated later mentioned Good. For example, the length in the X direction of a bundle (web) TW of thin paper sheets T to be stored may be equal to the length in the Y direction or may be shorter than the length in the Y direction.

  The packaging bag 10 is formed of a flexible film F1. The packaging bag 10 is manufactured by pillow packaging in which the film F1 is bag-shaped by side sealing, and the bag-like film is further folded in a gusset shape and sealed by a heat seal H (see FIGS. 1 and 2). ). In addition, this embodiment is not limited to this pillow packaging, It may be manufactured by the caramel packaging etc. in which a gusset is formed. In addition, the packaging bag 10 is an example of the packaging bag in this invention. The film F1 is an example of the first film in the present invention.

  The film F1 used for the packaging bag 10 is polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), A general purpose resin film generally used as a thin paper package such as polyamide (PA) can be used. As polyethylene, high density polyethylene, low density polyethylene or the like can be used.

  In addition, as a material of the film F1, polyethylene, polypropylene, polyethylene terephthalate and the like are preferable from the viewpoint of being flexible and excellent in handleability, high in sealing property when heat sealed, and inexpensive. In addition, polyethylene and polypropylene are more preferable in terms of being odorless, excellent in water resistance and chemical resistance, and capable of mass production at low cost. The film F1 may be a laminate film in which a plurality of films are laminated, or may be a film made of a mixture of two or more of the above resins.

  The thickness of the film F1 is optional. In addition, the thickness of the film F1 is preferably in the range of 20 to 70 μm, and in the range of 25 to 60 μm from the viewpoints of giving sufficient strength to the packaging bag 10, securing flexibility and lightness, and suppressing costs. Is more preferred.

  In the packaging bag 10, thin paper T is accommodated. The stack of thin paper sheets T is configured such that thin paper sheets are pulled out in a pop-up manner. For example, the thin paper sheets T are each folded in half so that the folding direction is alternated, and the edge of the folded back surface enters each of the folded inner surfaces of the adjacent thin paper sheets T, that is, alternately It is stacked in the inserted state. Then, when one set or a set of stacked sheets is taken out, the subsequent sheets will be partially ejected to the outside. The tissue sheet may be folded in three or four as long as it can be pulled out in a pop-up manner.

The tissue T to be stored may be a hygienic tissue such as tissue paper, toilet paper, kitchen paper, paper hand towel, paper cloth towel, wiper and the like. The basis weight of one ply of thin paper is preferably in the range of 10 to ²⁰ g / m ² , and the thickness of two plies of thin paper is preferably in the range of 130 to 200 μm.

  Here, the basis weight means a value measured based on JIS P 8124 (1998). The paper thickness is adjusted sufficiently under the conditions of JIS P 8111 (1998), and then using a dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Works) under the same conditions. Mean the measured value.

  The specific procedure for measuring this paper thickness is as follows. First, make sure that there is no dust or dirt between the plunger and the measuring table, place the plunger on the measuring table, move the memory of the dial thickness gauge and adjust the zero point. The plunger is then raised to place the sample on the test bench, the plunger is slowly lowered and the current gauge is read. In this case, just put the plunger. The terminals of the plunger are made of metal and a circular plane with a diameter of 10 mm is perpendicular to the paper plane. In addition, the load at the time of the measurement of this paper thickness is about 70 gf. The paper thickness is an average value obtained by measuring 10 times.

Such stacks of tissue paper can be produced, for example, by means of a rotary or multistand interfolder.

  The outlet 20 is formed on the upper surface 11 of the packaging bag 10 and constitutes a portion for extracting the thin paper T stored in the packaging bag 10. Specifically, as shown in FIGS. 1 and 2, the takeout port 20 is formed by breaking a perforation 40 described later disposed in the central portion 12 of the upper surface 11 of the packaging bag 10. In the present embodiment, the outlet 20 has an elongated oval shape extending in the longitudinal direction of the paper package 100. In addition, the shape of the extraction port 20 is not limited to such an elliptical shape, and may be a rectangle, a circle, a linear shape, or the like. The outlet 20 is an example of the outlet in the present invention.

  The paper package 100 further comprises a sheet 30. The sheet 30 is laminated on the upper surface 11 of the packaging bag 10 as shown in FIGS. 1 and 2. Specifically, the sheet 30 covers the outlet 20 formed on the upper surface 11 of the packaging bag 10 and is adhered to the upper surface 11 of the packaging bag 10 or a portion 13 of the upper surface 11 of the packaging bag 10 is exposed. It is stuck.

  When the sheet 30 is adhered to the upper surface 11 of the packaging bag 10, an adhesive may be used, and when the sheet 30 is adhered to the upper surface 11 of the packaging bag 10, an adhesive may be used. In addition, when laminating | stacking the sheet | seat 30 on the upper surface 11 of the packaging bag 10, it is preferable to use an adhesive by the point by which the effect of this invention is acquired reliably.

  The sheet 30 is formed of a flexible film F2. The film F2 used for the sheet 30 may be either the same material as the film F1 used for the packaging bag 10 or a different material. The sheet 30 is an example of a sheet in the present invention. The film F2 is an example of the second film in the present invention.

  As the film F2 used for the sheet 30, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), polyamide A general-purpose resin film generally used as a thin paper package such as (PA) can be used. As polyethylene, high density polyethylene, low density polyethylene or the like can be used.

  The material of the film F2 is also preferably polyethylene, polypropylene, polyethylene terephthalate or the like because it is flexible and excellent in handleability, high in sealability when heat sealed, and inexpensive. In addition, polyethylene and polypropylene are more preferable in terms of being odorless, excellent in water resistance and chemical resistance, and capable of mass production at low cost. Moreover, the film F2 may be a laminate film in which a plurality of films are laminated, or may be a film made of a mixture of two or more of the above resins.

  The thickness of the film F2 is also optional. In addition, the thickness of the film F2 is preferably in the range of 20 to 70 μm, and in the range of 25 to 60 μm from the viewpoints of giving sufficient strength to the packaging bag 10, securing flexibility and lightness, and suppressing costs. Is more preferred.

  The paper package 100 further has perforations 40. The perforations 40 are formed on the top surface 11 and the sheet 30 of the packaging bag 10 as shown in FIGS. 1 and 2. The perforations 40 are formed by a plurality of slits S penetrating the sheet 30 and the upper surface 11 of the packaging bag 10 in the thickness direction (the Z direction in FIG. 1). Although the pitch of the perforations 40 is arbitrary, it is preferable to be a pitch that can maintain the strength such that the perforations 40 do not break during the manufacture, transport or the like of the thin paper package 100. The perforations 40 are an example of the incisions in the present invention.

  In the thin paper package 100, the take-off port 20 is formed in the upper surface 11 and the sheet 30 of the packaging bag 10 by breaking the perforation 40. Breaking the perforations 40 means that the upper surface portion of the packaging bag 10 located between the plurality of slits S constituting the perforations 40 is broken and the slits S are connected. Therefore, for example, by arranging the perforations 40 in an elliptical shape and breaking it, the elliptical extraction port 20 as in the present embodiment is formed. Also, by arranging the perforations 40 in a straight line and breaking it, a straight line outlet can be formed.

  In the present embodiment, the sheet 30 formed of the flexible film F2 is stacked on the upper surface 11 of the packaging bag 10 formed of the flexible film F1 as described above, and the upper surface 11 of the packaging bag 10 A perforation 40 is formed to penetrate the sheet 30 in the thickness direction. Thereby, in the present embodiment, as shown in FIG. 2, the periphery 21 of the outlet 20 formed by breaking the perforation 40 has a two-layer structure in which the film F1 and the film F2 are laminated.

  In this embodiment, the strength of the periphery 21 of the outlet 20 can be increased by configuring the periphery 21 of the outlet 20 with such a two-layer structure. Thereby, when the perforation 40 is broken, it is possible to prevent the circumference 21 of the extraction port 20 from being cut or torn. Therefore, the present embodiment can suppress breakage of the outlet 20 at the time of opening the thin paper package 100 (see FIGS. 6 and 7).

  Further, in the present embodiment, by increasing the strength of the periphery 21 of the outlet 20, it is possible to prevent the periphery 21 of the outlet 20 from being cut or torn even when extracting the thin paper T from the outlet 20. Can. Therefore, in the first aspect, it is possible to prevent the removal opening 20 from being damaged even when the thin paper paper package 100 is used after opening (see FIGS. 6 and 7).

  Furthermore, in the present embodiment, since it becomes difficult for the takeout port 20 to be broken when the thin paper paper package 100 is opened, it is not necessary to make perforations easy to break in advance by reducing the pitch of the perforations 40 or the like. Therefore, as described above, the strength of the periphery 21 of the takeout port 20 can be increased, and the product defect of the paper package 100 due to breakage of the perforation 40 at the time of manufacture of the paper package 100 or transportation before opening. It can prevent.

  In the thin paper paper package 100 of the present embodiment (first embodiment), it is preferable to use different materials for the film F1 and the film F2 from the viewpoint of obtaining the effect of the present invention with certainty. For example, when polyethylene (PE) is used as the film F1, polypropylene (PP) is used as the film F2, and when polypropylene (PP) is used as the film F1, polyethylene (PE) is used as the film F2.

  Thus, by changing the material of the film F1 which is the first film and the material of the film F2 which is the second film, the periphery 21 of the outlet 20 formed by breaking the perforation 40 is made of the material Is a two-layer structure in which two different films are laminated (see FIGS. 2 and 3). In addition, physical properties such as breaking strength and breaking elongation differ between two films different in material as described above, for example, polyethylene (PE) and polypropylene (PP).

  As a result, as shown in FIG. 3 (C1 portion in FIG. 1), when breaking the perforation 40, the two films are drawn in the surface direction of the laminated surface LS of the upper surface 11 of the packaging bag 10 and the sheet 30. A force is generated, and in the vicinity of the perforation 40, the packaging bag 10 and the sheet 30 are likely to be broken alternately. As a result, the force to break the perforation 40 is easily transmitted along the perforation 40 in the direction of the arrow BD in FIG. 3, so that the periphery 21 of the outlet 20 is reliably prevented from being cut or torn. Can. Therefore, in the present embodiment, it is possible to further suppress breakage of the takeout port 20 at the time of opening the thin paper sheet package 100.

  FIG. 4 is a view showing a paper package according to an embodiment (second embodiment) of the present invention, and FIG. 5 is a cross-section of the C2 portion of FIG. 4 in the X direction to explain the function and effect of the paper package It is a figure to do. In addition, in FIG. 5, in order to make an understanding easy, hatching of the cross section is abbreviate | omitted and orientation was shown typically.

  In the thin paper paper package 100 of the present embodiment (second embodiment), the upper surface 11 of the packaging bag 10 such that the orientation direction (fiber direction) OD1 of the film F1 and the orientation direction (fiber direction) OD2 of the film F2 intersect. The sheet 30 is laminated. In such a configuration, when breaking the perforations 40, it is possible to make the attracting force between the film F1 and the film F2 cross in the surface direction of the laminated surface LS of the upper surface 11 of the packaging bag 10 and the sheet 30. .

  In particular, in the present embodiment, as shown in FIG. 5 (C2 portion in FIG. 4), the orientation direction OD1 of the film F1 is a direction along the longitudinal direction of the perforation 40 (X direction in FIG. 4) Of the film F1 is perpendicular to the alignment direction OD1 of the film F1. That is, the sheet 30 is laminated on the upper surface 11 of the packaging bag 10 such that the orientation direction OD1 of the film F1 and the orientation direction OD2 of the film F2 are orthogonal to each other.

  Thereby, in the present embodiment, when the perforations 40 are broken, a force of attraction between the film F1 and the film F2 is reliably obtained in the surface direction of the laminated surface LS of the upper surface 11 of the packaging bag 10 and the sheet 30. Be Therefore, in the vicinity of the perforation 40, the force for breaking the perforation 40 is transmitted in the direction of the arrow BD shown in FIG. 5, and the packaging bag 10 and the sheet 30 are more easily broken alternately. As a result, the force to break the perforations 40 can be more easily transmitted along the perforations 40, so that it is possible to reliably prevent the circumference 21 of the outlet 20 from being cut or torn. Therefore, in the present embodiment, it is possible to further suppress breakage of the takeout port 20 at the time of opening the thin paper sheet package 100.

  Further, in the present embodiment, as shown in FIG. 4, the sheet 30 is laminated on the upper surface 11 of the packaging bag 10 so that the orientation direction OD1 of the film F1 and the orientation direction OD2 of the film F2 are orthogonal to each other. When the perforation 40 is broken, the other film F2 is perforated against the force to break one film F1 in the direction perpendicular to the direction along the perforation 40 (outward direction of the outlet 20). A force is generated to pull one of the films F1 in the direction along 40.

  Thereby, in the vicinity of the perforation 40, the force for breaking the perforation 40 is reliably transmitted in the direction of the arrow BD shown in FIG. 5, and the packaging bag 10 and the sheet 30 are easily broken alternately. Therefore, the force to break the perforations 40 can be easily transmitted along the perforations 40, so that it is possible to reliably prevent the circumference 21 of the outlet 20 from being cut or torn. Therefore, in the present embodiment, it is possible to further suppress breakage of the takeout port 20 at the time of opening the thin paper sheet package 100.

<Paper product>

The perforations 40 are formed by forming. In the present embodiment, the perforations 40 are formed by the die cutter 70, but the perforations 40 may be formed by using a perforation blade instead of the die cutters. The perforation forming step ST2 is an example of a second step in the method for producing a thin paper product according to the present invention.

  In the web accommodation step ST3, the thin paper T is accommodated in the packaging bag 10 in which the film F1 is folded. Specifically, as shown in FIG. 9, a laminate obtained by folding the web TW of the thin paper T while folding the laminate of the film F1 and the film F2 in which the perforations 40 are formed by the die cutter 70 with the folder 80 House in space 10). In addition, web accommodation process ST3 is an example of the 3rd process in the manufacturing method of the thin paper product which concerns on this invention.

  In the sealing step ST4, the packaging bag 10 (laminate of the film F1 and the film F2) containing the thin paper T is sealed. Specifically, as shown in FIG. 9, the longitudinal ends of the packaging bag 10 (laminated film F1 and film F2) in which the web TW of thin paper T is accommodated in the folder 80 are heat sealed by the sealer 90. While cutting the seal part. Thereby, a thin paper product in which the thin paper T is accommodated in the thin paper package 100 is obtained. The sealing step ST4 is an example of a fourth step in the method of manufacturing a thin paper product according to the present invention.

  The obtained thin paper product is provided with the extraction port 20 for taking out the thin paper T, and becomes a thin paper product in which the thin paper T is accommodated in the thin paper package 100 formed by breaking the perforation 40. Therefore, the effect of the above-mentioned thin paper paper package 100 is obtained as it is (refer FIG. 6, FIG. 7).

  That is, since the thin paper product manufactured by the method for manufacturing the thin paper product according to the present embodiment is configured using the thin paper packaging body 100, the periphery of the outlet formed by breaking the perforation is It can be set as the 2 layer structure on which the film F1 which is 1 film, and the film F2 which is 2nd film were laminated | stacked. Thereby, according to the thin paper product according to the embodiment of the present invention, it is possible to suppress the damage of the takeout opening at the time of opening, suppress the damage of the takeout opening at the time of use after opening, and product failure of the thin paper package. An effect such as preventing can be obtained.

  In addition, in the manufacturing method of the thin paper product of this embodiment, the film from which a material differs with the film F1 and the film F2 is used. Thus, by making the material of the film F1 different from the material of the film F2, in the obtained thin paper product, the same function and effect as the thin paper product using the thin paper package 100 of the first embodiment described above can be obtained.

  That is, in the thin paper product obtained by the method for manufacturing the thin paper product according to the present embodiment, when the perforation 40 is broken, the two films between the two films in the surface direction of the laminated surface LS of the upper surface 11 of the packaging bag 10 and the sheet 30 At the perforations 40, the packaging bag 10 and the sheet 30 are likely to be broken alternately. As a result, the force to break the perforations 40 can be easily transmitted along the perforations 40, so that it is possible to reliably prevent the circumference 21 of the extraction port 20 from being cut or torn. Therefore, in the thin paper product obtained by the method for manufacturing a thin paper product according to the present embodiment, it is possible to further suppress the breakage of the takeout port 20 when the thin paper package 100 is opened (see FIG. 3).

  Further, in the film laminating step ST1 in the method for producing a thin paper product according to this embodiment, the orientation direction OD1 of the film F1 is a direction along the longitudinal direction of the perforation 40 (see X direction in FIG. 4) and the orientation direction of the film F2. The film F2 is laminated on the film F1 such that the OD2 is orthogonal to the orientation direction OD2 of the film F1. As described above, since the film F2 is laminated on the film F1 so that the orientation directions of the film F1 and the film F2 are orthogonal to each other, the obtained thin paper product uses the thin paper package 100 of the second embodiment described above. The same effects as those of the paper products produced can be obtained.

  That is, when the perforations 40 are broken, a force of attraction between the film F1 and the film F2 can be reliably obtained in the surface direction of the laminated surface LS of the upper surface 11 of the packaging bag 10 and the sheet 30. Therefore, in the vicinity of the perforation 40, the force for breaking the perforation 40 is transmitted in the direction of the arrow BD shown in FIG. 5, and the packaging bag 10 and the sheet 30 are more easily broken alternately. As a result, the force to break the perforations 40 can be more easily transmitted along the perforations 40, so that it is possible to reliably prevent the circumference 21 of the outlet 20 from being cut or torn. Therefore, in the thin paper product obtained by the method for manufacturing a thin paper product according to the present embodiment, it is possible to further suppress breakage of the takeout port 20 when the thin paper package 100 is opened.

  Hereinafter, the present embodiment will be specifically described using examples. The measurement and evaluation of each example and comparative example were performed as follows.

[Openability]
The openability of the delivery port 20 was verified for the thin paper paper package 100 in which the delivery port 20 was formed on the upper surface 11 of the packaging bag 10 containing the thin paper T. In the verification of the openability, the shape of the outlet 20 of the thin paper paper package 100 is an elliptical shape, and the dimension of the outlet 20 is a length of 190 mm in the longitudinal direction (see X direction in FIG. 1) and a direction orthogonal to the longitudinal direction. A perforation 40 was formed along the outlet 20 so as to have a width of 30 mm (see the Y direction in FIG. 1). The verification of openability uses a digital force gauge (Model: Z2-20N manufactured by Imada Co., Ltd.) to clip the end of the takeout port 20 of the thin paper paper package 100 in the longitudinal direction (see X direction in FIG. 1). Hold the thin paper paper package 100 on a flat table with your hand or adhesive tape etc., and slowly in the direction parallel to the longitudinal direction of the thin paper paper package 100 (see X direction in Fig. 1). The peak of the opening resistance value (gf) was measured when pulled out (about 30 mm of perforations were broken in about 1 second). The size of the thin paper paper package 100 was set to a width of 225 mm, a depth of 105 mm, and a height of 47 mm by using “Eliale Cut Tissue 160 (320 sheets) manufactured by Daio Paper Co., Ltd.”. The opening resistance value was taken as the average value of the results of measuring the opening resistance value three times for the thin paper paper package 100. In the evaluation of the opening property, when the opening resistance value was 450 gf or more, the strength of the outlet 20 was evaluated as high (good).
