[Figure 6] FIG. 4 is a front view of a packaging bag according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to Figures 1 to 5. However, the present invention is not limited to this embodiment.

[0018] The sanitary tissue paper product package according to the present invention contains a plurality of sanitary tissue paper products and gusset-packages them, and the sanitary tissue paper products contained in the sanitary tissue paper product package according to the present invention include toilet rolls, film-wrapped sanitary tissue paper (e.g., film-wrapped tissue paper, film-wrapped kitchen towels), kitchen towel rolls, hand towel rolls, etc. In the following, in one embodiment of the present invention, 12 toilet rolls (2 x 2 x 3) will be described as the sanitary tissue paper product.

[0019] In this specification and claims, the terms "top surface" and "bottom surface" refer to the surfaces of the film gusset packaging bag itself. However, these terms are used merely for convenience and do not, of course, define absolute positions in the direction of gravity. The same applies to terms such as "top" and "bottom."

[0020] Furthermore, in the present specification and drawings, the "height direction," "width direction," and "depth direction" are all orthogonal to each other.

[0021] Furthermore, in the description and claims of this specification, the term "rectangle" not only includes rectangular shapes but also square shapes, and also includes approximate rectangular shapes and approximate square shapes.

[0022] First Embodiment Fig. 1 is an overall perspective view of a sanitary thin paper product package 1 in which a sanitary thin paper product 2 is stored in a packaging bag according to a first embodiment of the present invention, and Fig. 2 is a front view of a packaging bag 1p according to this embodiment. The dashed lines in Fig. 2 represent the folds of the film gusset of the packaging bag 1p, and the heat-sealed portion 20 and the reinforcing heat-sealed portion 30 join two sheets of film on the inside of the pair of folds (two-ply portion 11b) and four sheets of film on the outside (four-ply portion 11a).

[0023] As shown in Figures 1 and 2, the packaging bag 1p of this embodiment is a film gusset packaging bag that has a handle portion 11 on the top side, is configured to be able to store multiple sanitary thin paper products (toilet rolls) 2 inside, and has a finger hole 112 in at least two overlapping parts of the film of the handle portion 11, and the overlapping films in the handle portion 11 are joined by a heat seal portion 20 consisting of seal lines 21, 22 (22a, 22b) (or an elliptical seal line 24 described below (see Figure 4(b)))) that surround at least the finger hole 112, and a reinforcing heat seal portion 30 is provided between the upper side of the frame of the area surrounded by the seal lines 21, 22 (22a, 22b) (or the elliptical seal line 24 described below (see Figure 4(b)))) and the upper side of the edge of the finger hole.

[0024] This configuration makes it possible to prevent the film of the packaging from tearing when the user places his or her fingers through the finger holes 112 and carries the packaging.

[0025] In the present invention, the frame of the area surrounded by the seal line may be rectangular, and in this case, the reinforcing heat seal portion 30 may be provided between a pair of upper left and right corners of the frame of the surrounded area and a pair of upper left and right corners of the edge of the finger hole 112.

[0026] Specifically, in this embodiment, the seal lines surrounding the finger hole 112 are composed of at least two vertical seal lines 21 extending in the vertical direction (height direction of the packaging body 1) and at least two horizontal seal lines 22 (22a, 22b) extending in the left-right direction of the handle portion 11 (width direction of the packaging body 1), as shown in Figure 2, and the reinforced heat seal portion 30 forms a right-angled triangle with right-angled corners close to each other between a pair of upper left and right corners of the frame of the area surrounded by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22b and 22d and a pair of upper left and right corners of the edge of the finger hole 112.

[0027] In this embodiment, 12 toilet rolls 2 (2 x 2 x 3), which are the packaged items, are contained in the bag-shaped space between the handle portion 11, which also serves as the top sealing portion, and the bottom sealing portion 13.

[0028] The total weight of the packaged items may be 0.2 kg or more, 0.5 kg or more, 1.0 kg or more, or 2.0 kg or more. There is no particular upper limit to the total weight of the packaged items, but the upper limit may be, for example, about 5.5 kg. Even when about 5.5 kg of packaged items are stored, the above-mentioned configuration makes it possible to prevent the film of the package from tearing.

[0029] The handle 11 has four-ply sections 11a at both widthwise ends, where four films are overlapped, and two-ply sections 11b, where two films are overlapped, are formed between the four-ply sections 11a on both widthwise sides. A finger hole 112 is formed in this two-ply section 11b, and the overlapped films are heat-sealed together. The finger hole 112 can be formed by a slit.

[0030] As with the handle portion 11, the bottom side sealing portion 13 has a four-layer section formed at both widthwise ends by stacking four films, and a two-layer section formed between the four-layer sections on both widthwise sides by stacking two films, and the stacked films are heat-sealed together in a straight line along the widthwise direction.

[0031] Gusset packaging is a form of packaging in which multiple packaged items are enclosed in a bag-like space between the adhesive parts (top sealing part 11 and bottom sealing part 13) on the top and bottom sides, which are bonded by heat fusion or the like, and which has a gusset between the front and back.In this embodiment, too, a gusset 14 is formed between the handle part 11, which also serves as the top sealing part, and the bottom sealing part 13, between the front and back.

[0032] Such gusset packaging is produced, for example, by folding the sides of a cylindrical film gusset packaging bag, also known as a gusset tube, into the inside of the bag to flatten it, and then heat-sealing the top portion of the gusset tube to form heat-sealed portion 20, thereby forming handle portion 11 that also serves as a top-side sealing portion that seals the top-side opening, and then expanding the bottom-side opening of the film gusset packaging bag precursor with the top side sealed, and inserting the toilet rolls 2 (12 rolls packed horizontally in this embodiment) that are to be packaged, and then sealing the bottom side using an appropriate sealing means such as heat-sealing to form bottom-side sealing portion 13.

[0033] In the present invention, it is sufficient that a plurality of sanitary thin paper products are stored in a film gusset packaging bag 1p having a handle 11 on the top side, and the bottom sealing portion 13 is not limited to a configuration in which overlapping films are heat-sealed linearly along the width direction, but may be sealed by overlapping heat-seal packaging. Also, the handle 11 is not limited to a configuration that doubles as the top sealing portion, but for example, a top sealing portion may be separately provided between the handle 11 and the storage portion for the film-wrapped tissue paper 2, in which overlapping films are heat-sealed linearly along the width direction to seal.

[0034] In this embodiment, the bag further includes a reinforcing film 40 that is superimposed on the handle portion 11, and the reinforcing film 40 is joined to the handle portion 11 by a heat seal portion 20. In the four-ply section 11a, five films including the reinforcing film 40 are heat-sealed together, and in the two-ply section 11b, three films including the reinforcing film 40 are heat-sealed together. This further prevents the film of the package from tearing.

[0035] The thickness of the reinforcing film 40 is preferably 60 to 110 μm, from the viewpoint of further preventing the film of the packaging body from tearing.

[0036] In this embodiment, two horizontal seal lines 22 (22c, 22d) are provided above the finger hole 112 in the area surrounded by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22a and 22b in the handle portion 11. In the present invention, seal lines can also be added outside the area surrounded by the seal lines. For example, a pair of additional vertical seal lines may be provided outside the pair of vertical seal lines 21, aligned with the pair of vertical seal lines 21.

[0037] The width of the horizontal seal line 22 and the vertical seal line 21 may be 1 to 3 mm, and is preferably 2 mm or less from the viewpoint of facilitating sealing processing.

[0038] In this embodiment, seal interruption portions 23 that function as air vent holes are provided on the left and right sides of the horizontal seal lines 22a and 22b.

[0039] In this embodiment, a slit capable of forming the finger hole 112 is provided in the handle portion 11 at one location in the center of the area surrounded by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22b and 22d.

[0040] FIG. 3 is a schematic diagram illustrating a slit group 50 formed in the handle portion 11 of the packaging bag according to this embodiment. As shown in FIG. 3, the slits capable of forming the finger holes 112 are configured as the slit group 50. The slit group 50 basically includes two outer slits 51a (first slits) located on the outer sides in the left-right direction and two inner slits 51b (second slits) located between the two outer slits 51a. In the example shown in FIG. 3, the outer slits 51a include an arc-shaped portion extending in the vertical direction. The arc-shaped portion of the outer slit 51a bulges outward in the left-right direction. The outer slit 51a also has a linear portion extending parallel to the left-right direction from the upper end of the arc-shaped portion toward the inside in the left-right direction. In other words, the upper end (upper end) of the outer slit 51a extends further toward the inside in the left-right direction than the lower end (lower end) of the outer slit 51a. As described above, the outer slit 51a is composed of an arc-shaped portion extending vertically and a linear portion extending inward in the left-right direction from the upper end of this arc-shaped portion. On the other hand, the inner slit 51b is a slit that extends linearly parallel to the left-right direction. The inner slit 51b is located close to the upper end of the outer slit 51a. A gap is provided between the outer slit 51a and the inner slit 51b, and this gap functions as the temporary fastening portion 52. The temporary fastening portion 52 is a portion that is intended to be broken when forming the finger hole 112 in the handle portion 11, and breaking this temporary fastening portion 52 connects the outer slit 51a and the inner slit 51b. Note that the inner slit 51b is not provided at the lower end of the outer slit 51a. Therefore, even if the temporary fastening portion 52 is broken, the film member is not separated from the handle portion 11 but remains intact.

[0041] In the embodiment shown in FIG. 3, a substantially V-shaped slit 51c is formed at the inner end of the two linear inner slits 51b in the left-right direction. This substantially V-shaped slit 51c may be connected to the inner slit 51b or may be located approximately 1 to 5 mm away from the inner slit 51b. The apex of the V-shaped substantially V-shaped slit 51c faces downward in the up-down direction. In the example shown in FIG. 3, the two linear slits forming the substantially V-shaped slit 51c are spaced apart at the portion corresponding to the V. However, the two linear slits forming the substantially V-shaped slit 51c may be connected. The substantially V-shaped slit 51c is located in the center of the handle portion 11 in the left-right direction. Therefore, when gripping the handle portion 11, the middle finger or index finger of a user's hand can easily be inserted into the substantially V-shaped slit 51c. In this way, by providing a substantially V-shaped slit 51c in the approximate center of the handle portion 11, it becomes easier to insert a finger into the slit group 50. Furthermore, when a fingertip is inserted into the slit group 50, the substantially V-shaped slit 51c first opens, and then one or more temporary fastening portions 52 existing around it break. As a result, the finger hole 112 can be easily formed even with one hand.

[0042] Furthermore, as shown in FIG. 3, a linear dividing slit 51d extending vertically is formed at a position spaced downward from the apex of the substantially V-shaped slit 51c. This dividing slit 51d can also be replaced with a perforation. Thus, when the temporary fastening portion 52 between the substantially V-shaped slit 51c and the dividing slit 51d is torn, the dividing slit 51d functions to divide the film portion between the two outer slits 51a into two halves, left and right. By providing the dividing slit 51d approximately directly below the substantially V-shaped slit 51c, the finger hole 112 can be formed more easily.

[0043] 2 and 3, the substantially V-shaped slit 51c and the dividing slit 51d are located in the center of the handle portion 11 in the left-right direction. Specifically, the substantially V-shaped slit 51c and the dividing slit 51d are formed between the left and right gussets 14 of the packaging bag 1p, in a region where the number of laminated layers of film is reduced. By forming the substantially V-shaped slit 51c and the dividing slit 51d in the region where the number of laminated layers of film is reduced in the center of the handle portion 11, it becomes easier to insert a finger into the substantially V-shaped slit 51c. As a result, inserting a finger into the substantially V-shaped slit 51c makes it easier to break the temporary fastening portions 52 located around the slit, and thus makes it easier to form the finger hole 112.

[0044] In the present invention, the finger holes 112 and the slits that can form them are not limited to the shapes described above (see the modified examples described later and FIG. 4(a) and the like). Two or more circular holes may be provided on the handle portion 11, spaced apart in the width direction.

[0045] In this embodiment, the reinforced heat-sealed portion 30 forms a right-angled triangle with two adjacent right-angled corners at a pair of upper left and right corners of the frame of the area surrounded by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22b and 22d. By arranging the reinforced heat-sealed portion 30 so that its right-angled corners are adjacent to each other at the corners where the weight of the product is likely to be applied, tearing of the film of the package can be further suppressed.

[0046] In the present invention, the right angles of the right triangle may contact a pair of upper left and right corners of the frame of the enclosed area (see FIG. 4(a) described later). This further prevents the film of the packaging body from tearing. Regarding the size of the right triangle of the reinforcing heat seal portion 30, one of the two sides of the right triangle having a length of about 10 mm, but this is not limited to this in the present invention. Also, in the present invention, the reinforcing heat seal portion may be in the form of a diagonal seal, as shown in FIG. 5(c) described later.

[0047] The shortest distance between the reinforcing heat-sealed portion 30 and the finger hole 112 (the shortest distance connecting the end of the reinforcing heat-sealed portion 30 and the edge of the finger hole 112) may be 1 to 20 mm. From the viewpoint of facilitating the sealing process, the shortest distance is preferably 2 mm or more.

[0048] The film for the film gusset packaging bag 1p can be any known heat-melting film. Examples include polyethylene films such as HDPE (high-density polyethylene), LDPE (low-density polyethylene), and LLDPE (linear low-density polyethylene), polystyrene, and polypropylene films, as well as laminated films of these. From an environmental perspective, biomass films derived from plant materials such as sugarcane, potato (starch), and corn can also be used. Even when using such biomass films, tearing of the film in the packaging can be prevented.

[0049] Similar known films can also be used as the reinforcing film 40. From the viewpoints of cost and ease of opening, the film and reinforcing film of the film gusset packaging bag 1p are preferably polyethylene films such as LDPE (low density polyethylene) film and LLDPE (linear low density polyethylene) film, among the above-mentioned films.

[0050] The thickness of the film of the gusset packaging bag 1p is preferably 75 μm or less from the viewpoint of packaging processing (spreading the film with a bucket and folding it with air), and is preferably 15 μm or more from the viewpoint of further preventing the film of the packaging body from tearing.

[0051] In this embodiment, the reinforcing heat-sealed portion 30 is provided between a pair of upper left and right corners of the frame of the area surrounded by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22b and 22d and a pair of upper left and right corners of the edge of the finger hole. In the present invention, the reinforcing heat-sealed portion 30 may be provided between the upper center of the frame of the surrounded area and the upper center of the edge of the finger hole.

[0052] 4A and 4B are diagrams illustrating the patterns of the heat-sealed portion 20, the reinforcing heat-sealed portion 30, and the finger hole 112 provided in a packaging bag 1p according to a modification of this embodiment, with FIG. 4A showing a first modification and FIG. 4B showing a second modification. FIG. 5A is a diagram illustrating the pattern of the shape of the reinforcing heat-sealed portion 30 provided in a packaging bag 1p according to a modification of this embodiment, with FIG. 5A showing an arc-shaped portion, FIG. 5B showing a portion with a recess on the hypotenuse of a right triangle, and FIG. 5C showing a diagonal line-shaped portion. Of the elements constituting the packaging bag according to the modification of this embodiment, those having similar functions are designated by the same reference numerals as in the first embodiment, and their description will be omitted.

[0053] The reinforced heat-sealed portion 30 may be formed in a shape that matches the vertical seal line 21 and / or the horizontal seal line 22 (22a to 22d).

[0054] For example, as shown in Figure 4(a), the reinforced heat-sealed portion 30' has a right-angled triangle shape with right angles touching the upper left and right corners of the area surrounded by a pair of vertical seal lines 21 and a pair of horizontal seal lines 22b and 22d. In other words, the reinforced heat-sealed portion 30' is integrated with the vertical seal line 21 and the horizontal seal lines 22b and 22d.

[0055] In a modification of this embodiment, the finger hole 112' may be provided by a slit that can form a rounded rectangle, as shown in FIG. 4(a).

[0056] Furthermore, in a modification of this embodiment, as shown in FIG. 4(b), an elliptical seal line 24 may be provided instead of the pair of vertical seal lines 21 and horizontal seal lines 22a, 22b, 22c, and 22d, a finger hole 112 may be provided near the center of the area surrounded by the seal line 24, and a reinforcing heat-sealed portion 30'' may be provided between the finger hole 112 and the elliptical seal line 24. In this configuration, the reinforcing heat-sealed portion 30'' is provided between the upper center of the frame of the area surrounded by the elliptical seal line 24 and the upper center of the edge of the finger hole 112. In this embodiment, the shape of the reinforcing heat-sealed portion 30'' is elliptical, but is not limited to this, and various shapes such as rectangular and circular may be adopted in the present invention.

[0057] In a modified example of this embodiment, it is also acceptable to remove the horizontal seal lines 22c and 22d between the horizontal seal lines 22a and 22b in the first embodiment, provide a finger hole 112 in the center of the expanded area, and then provide a pair of right-angled triangular reinforced heat seal portions that are larger than those in the first embodiment at the upper left and right corners of the expanded area.

[0058] In a modification of this embodiment, instead of the right-angled triangular reinforced heat-sealed portion 30 of the first embodiment, an arc-shaped reinforced heat-sealed portion 30a as shown in FIG. 5(a) may be provided, or a reinforced heat-sealed portion 30b having a recessed hypotenuse as shown in FIG. 5(b), or a diagonally-shaped reinforced heat-sealed portion 30c as shown in FIG. 5(c). In FIG. 4(a), the reinforced heat-sealed portion 30' is a right triangle with right angles touching the upper left and right corners of the area enclosed by the pair of vertical seal lines 21 and the pair of horizontal seal lines 22b and 22d. In FIG. 5(c), the reinforced heat-sealed portion 30c is in the form of a diagonally-sealed portion, leaving an unsealed portion within the right triangle. In FIG. 5(c), the spacing D between the unsealed portions is, for example, approximately 5 mm.

[0059] As described above, the shape of the reinforced heat-sealed portion according to the present invention is not limited to a right triangle or the shapes described in the above-mentioned modified examples, and various shapes can be adopted as long as the effects of the present invention are achieved. For example, the size of the reinforced heat-sealed portion can be determined based on the weight of the sanitary tissue paper products to be stored (e.g., the weight of 12 toilet rolls).

[0060] In a modification of this embodiment, finger hole 112 may be provided in the four-ply portion of the film of handle portion 11. In the example shown in Fig. 2, a pair of circular or elliptical holes may be provided in the pair of four-ply portions 11a instead of one finger hole 112. In the present invention, it is also acceptable to provide two holes in the two-ply portion 11b.

[0061] According to this embodiment, it is possible to prevent the film of the packaging body 1 from tearing when the user carries the packaging body 1 with his or her fingers hooked through the finger holes 112. That is, when the user puts his or her fingers through the finger holes 112 of the handle 11 to carry the product, the stiffness of the film portion that is pulled by the weight of the product is ensured by the reinforcing heat-sealed portion 30, making this portion less likely to tear. This effect can also be achieved because the reinforcing heat-sealed portion 30 is positioned at a position that overlaps the tearing direction of the film of the handle portion of the packaging bag.

[0062] In other words, by providing a point seal or a sealed portion in a portion where the weight of the product is likely to be applied, the strength of the handle portion 11 of the packaging film gusset bag for sanitary thin paper products can be improved. In other words, by sealing and crimping the portion, the film in the position where the load is applied is integrated, improving the strength of the handle portion 11.

[0063] Furthermore, according to this embodiment, the strength of the packaging bag 1p of the packaging body 1 can be improved, which makes it possible to accommodate the increased weight of roll products and also makes it possible to make the film body thinner, which in turn contributes to decarbonization in terms of environmental considerations.

[0064] Second Embodiment The second embodiment of the present invention differs from the first embodiment in that the ranges of the four-layer portion 11a and the two-layer portion 11b are different.

[0065] 6 is a front view of a packaging bag according to a second embodiment of the present invention. Of the components constituting the packaging bag 1'p according to this embodiment, those having similar functions are given the same reference numerals as in the first embodiment, and descriptions thereof will be omitted.

[0066] The packaging bag 1'p of this embodiment can store 18 toilet rolls (2 x 3 x 3), and the area of ​​the two-ply section 11'b is wider than in the first embodiment, and the area of ​​the four-ply section 11'a is narrower than in the first embodiment.

[0067] In the handle portion 11' of the packaging bag 1'p of this embodiment, the reinforcing heat seal portion 30 is also provided between a pair of upper left and right corners of the frame of the area surrounded by a pair of vertical seal lines 21 and a pair of horizontal seal lines 22b and 22d, and a pair of upper left and right corners of the edge of the finger hole 112.

[0068] According to this embodiment, similarly to the first embodiment, it is possible to prevent the film of the packaging body from tearing when the user places his / her fingers through the finger holes 112 and carries the packaging body 1'p.

[0069] The present invention is not limited to the above-described embodiments or the modifications described throughout, and appropriate changes and modifications can be made without departing from the technical concept of the present invention.

[0070] For example, the first embodiment describes a case where 12 toilet rolls (2 x 2 x 3) are stored, and the second embodiment describes a case where 18 toilet rolls (2 x 3 x 3) are stored.
