Definitions

  • the present invention relates to a film-packaged tissue in which a pop-up type bundle obtained by folding and stacking a plurality of sheets of tissue paper is packaged by a film.
  • a tissue product in which a pop-up type bundle of sheets of tissue paper is stored in a storage container includes a so-called box tissue in which a paper box is used for a storage container, and a film-packaged tissue in which a resin packaging film is used for a packaging container.
  • This film-packaged tissue has advantages that the storage container that becomes waste after use can be compact, and that portability and unit selling price can be reduced.
  • a single straight line of take-out port forming perforations is formed at the center of a top surface of a packaging film serving as a storage container in the short direction along the maximum width of the longitudinal direction or a part of the width in the longitudinal direction, and the film-packaged tissue is used while a slit-shaped take-out port is formed by tearing of the perforations at the time of use (Patent Literature 1) .
  • the film-packaged tissue at such a linear slit-shaped take-out port may be lifted together with the packaging film when the tissue paper is pulled out, and cannot be pulled out smoothly in some cases because the packaging film is lighter than a paper box.
  • Such a lifting phenomenon is likely to occur when the length of the slit is shorter than the length of the top surface in the longitudinal direction.
  • a main object of the present invention is to provide a film-packaged tissue in which tissue paper does not easily fall into a packaging container even if the height of an internal bundle is lowered, the packaging container is not easily lifted when a sheet of the tissue paper is pulled out from a take-out port, and a part of a sheet of the tissue paper next exposed from the take-out port is likely to stand up after a sheet of the tissue paper is pulled out from the take-out port.
  • a first means is
  • a second means is
  • a third means is the film-packaged tissue according to the first or second means, in which two to five slits or perforations are formed on one edge.
  • the present invention provides a film-packaged tissue in which tissue paper does not easily fall into a packaging container even if the height of an internal bundle is lowered, the packaging container is not easily lifted when a sheet of the tissue paper is pulled out from a take-out port, and a part of a sheet of the tissue paper next exposed from the take-out port is likely to stand up after a sheet of the tissue paper is pulled out from the take-out port.
  • a tissue paper bundle 3 formed by folding and stacking a plurality of sets of tissue paper 2 is packaged by a flexible resin packaging film 4.
  • the tissue paper bundle 3 included in the film-packaged tissue 1 according to the present invention is obtained by folding a sheet of the tissue paper 2 in half, and folding and stacking a plurality of sheets of the tissue paper 2 such that folded pieces 2B of other sheets of the tissue paper 2 located above and below the folded sheet are located in an inner side 2A of the folded sheet.
  • the tissue paper bundle 3 is a pop-up type tissue paper bundle in which when one folded piece of an uppermost sheet is lifted upward, a folded piece of another sheet adjacent to the lifted sheet immediately below is dragged upward and lifted.
  • This tissue paper bundle 3 can be manufactured by a known multi-stand type or rotary type interfolder. Note that each of sheets of the tissue paper 2 constituting the bundle 3 of the tissue paper 2 has a ply structure in which two to three thin sheets each having a crepe are stacked and assembled. This tissue paper 2 is a dry type, not a so-called wet type impregnated with a chemical solution.
  • the tissue paper bundle 3 has a substantially rectangular parallelepiped shape having a pair of longitudinal side surfaces 3B in which folded edges 2C of sheets of the tissue paper 2 are lined up, a pair of short side surfaces 3A in which the folded edges 2C are not lined up, and a pair of flat surfaces (upper and lower surfaces) 3C connected to the short side surfaces 3A and the longitudinal side surfaces 3B.
  • a packaging form of the film-packaged tissue 1 according to the present invention is selected from known packaging types. Examples thereof include three-sided closed packaging, four-sided closed packaging, gusset packaging, pillow packaging, and caramel packaging. Gusset packaging and pillow packaging are suitable, and the illustrated pillow packaging with gusset is particularly suitable. In particular, an effect of the present invention is remarkable when pillow packaging with gusset is used in which a heat-sealing portion 30 obtained by heat-sealing an overlapped portion of the packaging film is located at a position facing the short side surface 3A where the folded edges 2C of the tissue paper 2 are not lined up in the tissue paper bundle 3.
  • the film-packaged tissue 1 according to the present invention has ring-shaped take-out port forming perforations 5 formed in a bundle longitudinal direction 3y on a top surface 10 facing an uppermost sheet of the tissue paper 2 of the bundle 3 of the packaging film 4. By tearing of the take-out port forming perforations 5, a take-out port 6 is formed on the top surface of the film-packaged tissue 1.
  • the tissue paper bundle 3 is a pop-up type, when an uppermost sheet of the tissue paper 2 of the bundle 3 is pulled out from thus formed take-out port 6, a part of a next sheet of the tissue paper located immediately below the pulled-out sheet is exposed from take-out port 6.
  • the take-out port forming perforations 5 have a ring shape formed by die cutting, and in particular, is elongated in the longitudinal direction 3y of the bundle 3 which is an extending direction of the folded edge 2C of the tissue paper 2 at the center of the bundle 3 in a short direction 3x, and has a length L2 shorter than a longitudinal length L1 of the bundle 3. Therefore, an area surrounded by the take-out port forming perforations 5 is removed by tearing of the take-out port forming perforations 5 to form the take-out port 6 having the same shape as the area surrounded by the take-out port forming perforations 5. Note that other perforations may be formed within the area surrounded by the ring-shaped take-out port forming perforations such that the area can be easily removed.
  • the size of the area surrounded by the take-out port forming perforations 5 is not necessarily limited, but is generally 5 to 25 mm in the short direction 3x of the bundle 3 and 100 to 150 mm in the longitudinal direction 3y of the bundle 3.
  • a cut-tie ratio of the take-out port forming perforations is not particularly limited. The cut-tie ratio can be appropriately set to a range in which the film can be easily cut off considering the material and thickness of the film.
  • the film-packaged tissue 1 according to the present invention has slits 50, 50... that are continuous with or close to edges 5E and 5E of the take-out port forming perforations 5 in the longitudinal direction, extend parallel to or in a direction away from a center line C extending in a short direction at the center of the take-out port forming perforations 5 in the longitudinal direction, and do not reach edges of the top surface 10.
  • a perforation in which a slit is formed by tearing may be formed instead of the slit.
  • the slit if the slit is continuous with the edge 5E of the take-out port forming perforations in the longitudinal direction, preferably, an end of the slit is continuous with a tie part and is not continuous with a cut part in the cut part and the tie part of the perforations. In this way, a risk that the slit is formed only by removing the area surrounded by the take-out port forming perforations 5 is reduced. Further, a risk that when the area surrounded by the take-out port forming perforations 5 is removed, the slit may be unintentionally torn, is reduced.
  • such small edge pieces 6B and 6B are formed. Therefore, when the tissue paper 2 is pulled out from the take-out port 6, a slit 6A between the small edge pieces 6B and 6B widens to reduce pull-out resistance, the tissue paper 2 can be pulled out smoothly, and the tissue paper 2 is less likely to be lifted together with the packaging film 4 at the time of pull-out. At the same time, an edge 2E of a sheet of the tissue paper 2 that is next pulled out from the take-out port 6 and exposed is inserted into the slit 6A and held, or, for example, the small edge pieces 6B and 6B act on the sheet of the tissue paper 2 like check valves. As a result, in particular, as illustrated in Fig.
  • the length of the slit or the like 50 is 2 to 20 mm, preferably 3 to 10 mm, and particularly preferably 3 to 6 mm.
  • the length is less than 2 mm, support by the small edge piece 6B and opening of the slit 6A may be insufficient, and reduction of the pull-out resistance of the tissue paper and support of the tissue paper 2 may be performed insufficiently.
  • the length exceeds 20 mm, a risk that the tissue paper 2 may be insufficiently supported increases.
  • the number of the slits or the like 50 is 2 to 5 for one edge 5E.
  • Three to six small edge pieces 6B are formed, and a space between the slits 6A can be widened according to a complicated shape change of the tissue paper when the tissue paper 2 is pulled out from the take-out port 6. Therefore, the tissue paper 2 can be pulled out more smoothly.
  • the number of the slits or the like 50 exceeds 5, a risk that the packaging film 4 may be unintentionally torn increases.
  • the slits are symmetrical with respect to the center in the short direction, or are evenly spaced and radial. An edge of the tissue paper 2 is easily supported evenly, and standing performance of the tissue paper is enhanced.
  • the specific shape of the take-out port forming perforations 5 is not necessarily limited, but examples thereof include an elliptical shape, an elongated rectangle, and an elongated rectangle with a rounded corner.
  • the edges 5E and 5E of the take-out port forming perforations 5 in the longitudinal direction preferably each have a curved shape that bulges toward the center in the short direction, such as a semicircle.

  • edges 5E and 5E in the longitudinal direction each have a curved shape that bulges toward the center in the short direction
  • the side edge portions 2E and 2E of the sheet of the tissue paper 2 to be pulled out in the bundle longitudinal direction are easily moved so as to be rolled up along the bulging shape.
  • a part of the sheet of the tissue paper 2 exposed from the take-out port 6 is likely to form a substantially tubular portion on both side portions 2E and 2E in the longitudinal direction as illustrated in Fig. 6 , is likely to become a self-supporting form having this substantially tubular portion as a pillar structure, the standing part is easily grasped, and a falling prevention property is enhanced.
  • a range of the length L2 of the take-out port forming perforations 5 according to the present invention in the longitudinal direction is 80% to 90%, and more preferably 84% to 88% of the longitudinal length L1 of the bundle 3.
  • a range of the length L2 of the take-out port forming perforations 5 according to the present invention in the longitudinal direction is 80% to 90%, and more preferably 84% to 88% of the longitudinal length L1 of the bundle 3.
  • Examples of a specific flexible resin film material constituting the packaging film 4 according to the present invention include: a single-layer film of a polyethylene film, a polypropylene film, a polyester film, a polyethylene terephthalate film, a nylon film, a vinylidene chloride film, or an ethylene vinyl alcohol copolymer; a laminate film obtained by appropriately stacking these films; and a gas barrier film obtained by subjecting any of these films to a surface treatment such as aluminum vapor deposition.
  • a polypropylene film and a polyethylene film are preferable from a viewpoint of cost. It is desirable that the film material has a thickness of 20 to 60 ⁇ m.

  • the number of plies and the number of sets of the tissue paper 2 constituting the tissue paper bundle 3 is 100 to 220 sets with 2 plies (two sheets stacked) as one set. It is desirable that the tissue paper bundle 3 has a shape of 30 to 50 mm in height, 155 to 215 mm in length in the longitudinal direction, and 100 to 130 mm in length in the short direction.
  • the tissue paper bundle 3 is manufactured by a rotary type interfolder.
  • the short direction of the bundle coincides with MD (Machine Direction) of the tissue paper. That is, when a part of a sheet of the tissue paper exposed from the take-out port stands up, MD with high paper strength becomes an up-down direction.
