[0006] Patent Document 1: Japanese Patent No. 5396917. Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, when multiple tissue paper product packages are stacked in a store or other location, the packages may tilt or collapse if ventilation is not quick and sufficient. Since this is not adequately considered in Patent Document 1, the tissue paper product packages described in Patent Document 1 may not be able to be stored or displayed in a stable state when stacked.

[0009] The purpose of this invention is to provide a sanitary tissue packaging that can quickly and fully vent air when multiple sanitary tissue packaging units are stacked in a store or other location, so as to prevent the sanitary tissue packaging units from tilting or collapsing.

[0010] means for solving problems

[0011] The first aspect of the present invention relates to a sanitary tissue packaging body that contains multiple sanitary tissue products inside a film-supported packaging bag, characterized in that at least one opening is provided on the top, front, back and / or side of the film-supported packaging bag, which functions as a valve.

[0012] This structure allows for rapid and thorough venting when multiple tissue paper product packages are stacked in stores or other locations, preventing the tissue paper product packages from tilting or collapsing.

[0013] According to a second aspect of the first aspect of the present invention, the sanitary tissue packaging body is characterized in that the film gusseted packaging bag has a handle on the top side, and the opening is formed on the top surface of the film gusseted packaging bag on the front side and the back side, which are separated by the handle.

[0014] With this structure, even when the handle is folded to either the front or back side of the top surface during storage, air can be reliably vented through the opening on either the front or back side, which is divided by the handle.

[0015] According to a first, second, or third aspect of the present invention, the packaging body for sanitary tissue paper products is characterized in that the opening portion is formed to be openable or closed via a slit flap.

[0016] This structure allows for both preventing dust and other foreign matter from entering the packaging of sanitary tissue products and effectively venting air out of the packaging.

[0017] According to the second aspect of the present invention, or the fourth aspect relating to the third aspect, the packaging body for sanitary tissue products is characterized in that the opening portion is symmetrically formed on the top surface with the handle portion as the boundary.

[0018] With this structure, openings on the front and back sides, divided by the handle, can be easily formed in one process in the packaging of sanitary tissue paper products by means of punching rollers.

[0019] The packaging body for sanitary tissue paper products according to the first aspect or the fifth aspect of the present invention is characterized in that the opening portion is provided with a plurality of openings, the total area of ​​which is 28 mm². 2 above.

[0020] This structure allows for more efficient, rapid, and complete exhaust.

[0021] According to the first aspect or the sixth aspect of the present invention, the sanitary tissue packaging body is characterized in that the sanitary tissue is a film-packaged tissue, and the film packaging bag of the film-packaged tissue is provided with an opening that functions as a valve.

[0022] This structure allows for rapid and thorough air venting of the film-wrapped tissues, further preventing the tissue packaging from tilting or collapsing when multiple tissue packaging units are stacked.

[0034] The following is a reference. Figures 1 to 8 The present invention will be described in detail with reference to the embodiments thereof. However, the present invention is not limited to the embodiments described herein.

[0035] The present invention relates to a packaging body for toilet paper products that houses multiple toilet paper products and uses a corner-supported packaging method. The toilet paper products housed in the packaging body include toilet paper rolls, film-wrapped tissues, kitchen towel rolls, and hand towel rolls. In one embodiment of the present invention, two tissues are grouped together, and multiple groups of tissues are alternately folded and stacked to form a stack, which is then packaged in a pillow-like or candy-like manner using a film. This film-wrapped tissue is then described as a toilet paper product. In the figures, double-dotted lines represent the film-wrapped tissues housed in the toilet paper product packaging body.

[0036] It should be noted that in this specification and claims, "top surface" and "bottom surface" refer to the surface of the film-supported packaging bag or the film packaging bag itself, and are used as a reference. However, these terms are merely for convenience and are not intended to refer to absolute positions in the direction of gravity. The same applies to terms such as "upper" and "lower".

[0037] Furthermore, in this specification, claims, and drawings, the "height direction," "width direction," and "depth direction" are orthogonal.

[0038] Furthermore, in this specification, the term "rectangle" refers not only to a rectangle but also to a square, as well as a roughly rectangular or roughly square shape; and the term "cuboid" refers not only to a cube but also to a roughly cuboid or roughly cubic shape.

[0039] In this specification, claims, and drawings, the term "opening" refers to, for example, a portion consisting of a slit flap and a small hole protruding outward through the slit flap, that is, functioning as a valve. Specifically, for example, when the contents of the sanitary tissue packaging or the sanitary tissue product expand or are compressed due to external pressure, the slit flap opens (protrudes), allowing air present inside the sanitary tissue packaging or the sanitary tissue product to escape outward through the small hole. After this escaping, the slit flap returns to its original position and closes due to the restoring force held at its base, thus performing the valve-like action described above in the "opening."

[0040] In this specification, claims and drawings, the term "area of ​​opening" refers to the area of ​​the region enclosed by the outer contour of the opening. For example, in the case where the opening is composed of a slit flap and a small hole formed by protruding outward through the slit flap, it refers to the area enclosed by the slit flap's cut and the straight line connecting the two ends of the cut.

[0041] <First Implementation>

[0042] Figure 1 This is an overall perspective view of the sanitary tissue paper product packaging body 1 according to the first embodiment of the present invention. Figure 2 This is a front view of the sanitary tissue paper product packaging body 1 according to this embodiment.

[0043] In this embodiment, such as Figure 1 As shown, it is a sanitary tissue product packaging body 1 containing multiple sanitary tissue products (film-wrapped paper towels) 2 inside a film-supported packaging bag 1p. The film-supported packaging bag 1p has a top-side sealing part 11 on the top surface. On the top surface of the film-supported packaging bag 1p, on the front side and the back side, which are divided by the top-side sealing part 11, there is an opening part 121 that functions as a valve.

[0044] This structure allows for rapid and sufficient air venting when multiple tissue paper product packages 1 are stacked in a store or similar location, preventing the tissue paper product packages 1 from tilting or collapsing. It should be noted that in this embodiment, two pairs of openings 121 are provided on the top surface of the film-supported packaging bag 1p, on the front and back sides of the inclined surface 12. However, this invention is not limited to this; the openings 121 can be located anywhere on the top, front, back, and / or side of the film-supported packaging bag 1p. The number of openings 121 is not particularly limited as long as there is one or more (see also the second and third embodiments described later).

[0045] In this embodiment, such as Figures 1 to 3(b) As shown, the tissue paper product packaging body 1 consists of a top 1A and a body 1B. The top 1A has a top-side sealing portion 11 on its top surface for sealing the opening on the top surface side, and a pair of inclined surfaces 12 located on the front and back sides to clamp the top-side sealing portion 11. The body 1B stores five film-wrapped tissues 2 in a horizontal arrangement. In this invention, the film-wrapped tissues 2 are not limited to being laid flat with their bottom surfaces stacked on top, but can also be placed vertically with their sides facing the bottom surface of the film-braced packaging bag 1p.

[0046] An angular gusseted packaging refers to a packaging form in which multiple items are wrapped within a bag-like space between the top and bottom sides, created by heat welding or other adhesive methods, and the packaging has a width between the front and back sides. In this embodiment, the angular gusseted packaging has a width 14 formed between the top-side sealing portion 11 and the bottom-side sealing portion 13, and between the front and back sides. Multiple film-wrapped tissues 2, which are the items to be packaged, are wrapped within the bag-like space between the top-side sealing portion 11 and the bottom-side sealing portion 13. It should be noted that in the top-side sealing portion 11, four overlapping portions 11a, formed by four films overlapping, are formed at both ends in the width direction, and two overlapping portions 11b, formed by two films overlapping, are formed between the four overlapping portions 11a on both sides in the width direction. The overlapping films are heat-sealed together in a straight line along the width direction. In addition, the bottom side sealing portion 13 is the same as the top side sealing portion 11, with four overlapping portions 13a formed by four films overlapping at both ends in the width direction, and two overlapping portions 13b formed by two films overlapping between the four overlapping portions 13a on both sides in the width direction, and the overlapping films are heat-sealed together in a straight line along the width direction.

[0047] Such a gusseted packaging is manufactured as follows: For example, the side of a cylindrical film gusseted packaging bag, referred to as a gusseted tube, is folded inward and flattened to form the top side of the gusseted tube. The top side of the gusseted tube is heat-sealed by heat fusion to form a top side sealing part 11 for sealing the top side opening. Then, the bottom side opening of the film gusseted packaging bag precursor that has sealed the top side is opened, and film packaging tissues 2 (five in this embodiment are horizontally packed) as the packaged items are inserted from here. After that, the bottom side is also sealed by a suitable sealing means such as heat fusion to form a bottom side sealing part 13. At this time, if an opening 121 is formed on the film-supported packaging bag p1 before inserting the film-packaged tissue 2 (five in this embodiment are inserted horizontally) through the bottom side opening of the film-supported packaging bag precursor, then when inserting the film-packaged tissue 2 through the bottom side opening of the film-supported packaging bag precursor, air can be vented through the opening 121 while the film-packaged tissue 2 is smoothly inserted through the bottom side opening of the film-supported packaging bag precursor.

[0048] In this embodiment, the opening 121 on the sanitary tissue packaging 1 is formed so that it can be opened or closed by a slit flap. With this structure, it is possible to prevent foreign objects such as dust from entering the sanitary tissue packaging 1 while reliably venting air out of the sanitary tissue packaging 1.

[0049] It should be noted that, in this invention, any structure that contains multiple sanitary tissue products (film-wrapped tissues 2) inside a film-supported packaging bag 1p with a top-side sealing portion 11 on the top side is acceptable. The bottom-side sealing portion 13 is not limited to a structure in which overlapping films are heat-sealed in a straight line along the width direction, but can also be sealed by heat-sealing and folding the packaging.

[0050] Figures 3(a) and 3(b) are enlarged top views of the periphery of the opening portion formed on the inclined surface of the top side of the sanitary tissue paper product packaging body according to the present invention. Figure 3(a) shows the shape of the opening portion 121 according to the first embodiment, and Figure 3(b) shows the shape of the opening portion 121' according to a modified example of the first embodiment.

[0051] The opening 121 is composed of a slit flap 121d and a small hole formed by protruding outward through the slit flap 121d. The slit flap 121d is a cut in a straight line or curve that continuously connects two sides of three points that are not on the same straight line, and can be opened or closed. In this embodiment, as... Figures 1 to 3(a) As shown, the opening 121 is formed by cutting a circular slit in the inclined surface 12 of the film gusseted packaging bag 1p and retaining a portion therein. In detail, as shown in FIG3(a), the opening 121 is formed into a generally circular shape by two semi-circular holes, with a circular slit cut and retaining the connecting portion 121c at the top and bottom. By retaining a portion in this way, the wing-shaped slit flap 121d can open or close the opening 121 at the slit location, thereby allowing air to escape through the opening 121 and preventing foreign objects such as dust from entering the opening 121. The area of ​​a single opening 121 (the area of ​​a single opening 121 formed by two semi-circular holes) can be set, for example, to 7 mm. 2 ~50mm 2 Furthermore, in order to achieve the effects of the present invention, the total area of ​​the opening portion 121 (area of ​​a single opening portion × number of opening portions (4 in this embodiment)) can be set to 28 mm. 2 ~200mm 2 In particular, if the total area of ​​the opening 121 is less than 28 mm... 2 If so, the exhaust efficiency will decrease.

[0052] It should be noted that, in this invention, the shape of the cut in the opening 121 is not limited to a circle; it can be approximately circular, elliptical, oval, clamshell-shaped, or polygonal, where two identical arcs are connected at both ends. Furthermore, in this invention, the portion retaining the cut in the opening 121 can be in various positions or shapes, as long as the desired effect is achieved. Additionally, this invention is not limited to the opening 121 being able to open or close via the cut flap 121d; the opening 121 can be formed as a circular or polygonal opening that is always open.

[0053] In a variation of the first embodiment of the present invention, as shown in FIG3(b), the cut flap 121'd has a V-shape in the opening portion 121', and the connecting portion between the ends of the cut is the base end of the cut flap 121'd. At this time, for example, when venting air from the inside of the sanitary tissue packaging body 1, the cut flap 121'd protrudes outward from this base end. After venting, the restoring force acts at this base end, and the cut flap 121'd returns to its original position, the small hole closes, and it plays a role in preventing dust from entering.

[0054] The film-packaged tissue 2 involved in this embodiment is formed by stacking tissues together. This stacked packaging is also known as candy-style packaging or folded packaging.

[0055] Specific examples of the soft resin-based packaging film constituting the outer packaging of the film-packaged tissue 2 include polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, polyvinylidene chloride film, single-layer film of ethylene-vinyl alcohol copolymer, or laminated film comprising suitable layers of these films, and gas barrier films to which surface treatments such as aluminum vapor deposition have been applied. Furthermore, from an environmental protection perspective, biomass films selected from plant raw materials such as sugarcane, potato (starch), and corn are preferred. From a cost perspective, polypropylene film and polyethylene film are preferred.

[0056] Furthermore, the packaging film constituting the outer packaging of the film-packaged tissue 2 can be a pear-shaped film with excellent appearance and feel. Moreover, if used for packaging scented items such as scented tissues, ethylene-vinyl alcohol copolymer resin films or polyethylene terephthalate resin films with excellent fragrance retention can be used. Alternatively, multilayer resin films with polyethylene resin films or polypropylene resin films laminated on one or both sides of the ethylene-vinyl alcohol copolymer resin film or polyethylene terephthalate resin film can be used to improve heat-sealing properties.

[0057] The film of the film-supported packaging bag 1p is made of polypropylene film and polyethylene film, which is preferred from the perspectives of cost and ease of opening. Examples of polyethylene films include linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), and medium-density polyethylene (MDPE). Alternatively, single-layer films of polyethylene terephthalate, nylon, polyvinylidene chloride, ethylene-vinyl alcohol copolymer, or laminated films containing suitable layers of these films, or gas barrier films with surface treatments such as aluminum vapor deposition, can be used. Similar to the packaging film constituting the outer packaging of the film-packaged tissue 2, from an environmental protection perspective, biomass films selected from plant raw materials such as sugarcane, potato (starch), and corn are preferred.

[0058] Previously, as an example of a sanitary tissue packaging body that houses multiple sanitary tissue products within a gusseted packaging, Patent Document 1 describes the following: The handle portion provided on the top side has an air hole that connects the inside and outside of the gusseted packaging bag in a manner that makes the sealing line discontinuous. This air hole allows for ventilation to prevent the gusseted packaging bag from expanding during the packaging process of the sanitary tissue products or from accidentally breaking while the sanitary tissue products are packaged.

[0059] However, when multiple tissue paper product packages are stacked in a store or other location, the packages may tilt or collapse if ventilation is not quick and sufficient. Since this is not adequately considered in Patent Document 1, the tissue paper product packages described in Patent Document 1 may not be able to be stored or displayed in a stable state when stacked.

[0060] According to this embodiment, when multiple sanitary tissue paper product packaging units 1 are stacked in a store or other location, air can be vented quickly and sufficiently to prevent the sanitary tissue paper product packaging units 1 from tilting or collapsing.

[0061] In this embodiment, the film packaging bag of the film-packaged tissue 2, which is a sanitary tissue product housed in the packaging body, does not have an opening. However, in a variation of this embodiment, in order to prevent unnecessary expansion of the film packaging bag of the film-packaged tissue 2, an opening 121 can be provided on the film packaging bag of the film-packaged tissue 2.

[0062] Figure 4 This is an overall perspective view of the film-packaged tissue 2 housed in a sanitary tissue product packaging body, as described in a variation of this embodiment. Elements having the same function among the constituent elements of the sanitary tissue product 2 according to this embodiment are marked with the same symbols as in the first embodiment of the present invention, and their descriptions are omitted.

[0063] With the stack of tissues stored inside the film packaging bag 2p, the film-packaged tissues 2 are roughly rectangular in shape, such as... Figure 4 As shown, on the film packaging bag 2p, the perforation line 220 for forming the tissue dispenser is formed in a straight line on the top surface 22. Additionally, as... Figure 4 As shown, two pairs of openings 121 are formed at intervals on a pair of long side portions 23 of the film packaging bag 2p. This structure prevents unnecessary expansion of the packaging bag 2p of the film-packaged tissue 2. It should be noted that the number of openings 121 is not limited to this, and the openings 121 can be formed on any of the long side portions 23 and short side portions 24 of the film packaging bag 2p, which is generally rectangular. The film-packaged tissue 2 with this structure can be housed in the sanitary tissue packaging body 1 according to the first embodiment of the present invention described above, or in the sanitary tissue packaging body 1', 1'' according to the second or third embodiment described below. In addition, similar to the sanitary tissue packaging body 1 according to the first embodiment of the present invention described above, the openings 121 are preferably formed so that they can be opened or closed by a slit flap, thereby preventing foreign objects such as dust from entering the film-packaged tissue 2 while reliably venting air out of the film-packaged tissue 2.

[0064] <Second Implementation>

[0065] The second embodiment of the present invention differs from the first embodiment in that the width of the top-side sealing portion 11 formed on the top surface side of the film gusseted packaging bag 1p is widened, and a handle portion 11h is provided so that the packaging body of the sanitary tissue paper product can be grasped and transported.

[0066] Figure 5 This is an overall perspective view of the sanitary tissue paper product packaging body 1' according to the second embodiment of the present invention. Figure 6 This is a front view of the sanitary tissue paper product packaging body 1' according to this embodiment. Figure 7 This is a top view of the sanitary tissue paper product packaging body 1' according to this embodiment. For elements that have the same function among the various elements constituting the sanitary tissue paper product packaging body 1' according to this embodiment, the same symbols as in the first embodiment of the present invention are used and their descriptions are omitted.

[0067] In this embodiment, the top side sealing portion 11 also serves as a handle portion 11h. In the four overlapping portions 11a and two overlapping portions 11b of the top side sealing portion 11, the overlapping films cover the entire area and are partially heat-sealed together to form a heat-sealed portion 111. A handle hole 112 is formed in the two overlapping portions 11b of the top side sealing portion 11.

[0068] In this embodiment, such as Figure 7As shown, in the tissue paper product packaging body 1', the opening portions 121 are symmetrically arranged in two pairs on the top surface, with the handle portion 11h as the boundary. With this structure, the opening portions on the front and back sides, separated by the handle portion, can be easily formed in a single process in the tissue paper product packaging body 1' using a punching roller or similar device. In this invention, the number of opening portions 121 is not limited to this; furthermore, it is permissible to have the opening portions 121 on either the front or back side of the top surface.

[0069] In this embodiment, two carrying holes 112 are spaced apart along the width of the handle portion 11h. This structure disperses the force acting on the handle portion 11h during transport, effectively improving the overall strength of the handle portion 11h. In this invention, one carrying hole 112 can be provided on the handle portion 11h, or three or more carrying holes 112 can be spaced apart along the width of the handle portion 11h, or the handle portion 11h can be completely devoid of carrying holes 112.

[0070] In this embodiment, in the handle portion 11h, overlapping films are heat-sealed in a dot-matrix pattern across the entire area of ​​the handle portion 11h. This structure creates an uneven surface throughout the entire handle portion 11h, thereby preventing slippage and improving operability during handling. Figure 5 and Figure 6 As shown, in the handle portion 11h, multiple rectangular heat-sealed portions 111 are formed at predetermined intervals in the horizontal and vertical directions by heat-sealing overlapping films. It should be noted that, in this invention, it is also permissible to not form heat-sealed portions 111 in the handle portion 11h.

[0071] In this embodiment, the shape of the dots in the heat-sealing portion 111 is rectangular, but it is not limited to this in the present invention. For example, squares, rounded polygons containing curves, circles, ellipses, etc., can be used. In addition, in this embodiment, the dot pattern of the heat-sealing portion 111 is set as a grid pattern in which the rectangular heat-sealing portions 111 are arranged at predetermined intervals in the horizontal and vertical directions. However, it is not limited to this in the present invention. Various arrangement patterns such as rhomboid grids can be used.

[0072] Reference Figure 5 and Figure 6In the handle portion 11h of the film-supported packaging bag 1'p, the preferred necessary condition for forming a structure with a handle hole 112 in the overlapping portion 11b of the two films is that (1) the depth dimension L2 of the sanitary tissue packaging body 1' is ≤ the width dimension L1×0.6 of the sanitary tissue packaging body 1', and (2) the width dimension L3 of the handle portion 11h is ≤ the width dimension L1×1.1 of the sanitary tissue packaging body 1'. Wherein, the value 1.1 in (2) above is a value taking into account the compression of the sanitary tissue packaging body 1' in the width direction.

[0073] In addition, the structure is not limited to the handle portion 11h also serving as the top side sealing portion. For example, a top side sealing portion for heat-sealing and sealing the overlapping films in a straight line along the width direction can be separately provided between the handle portion 11h and the storage portion of the film-packaged tissue 2.

[0074] In the past, especially in the structure described in Patent Document 1, there were problems such as the air vents being blocked and unable to vent when the handle was folded to either the front or back side of the top surface during storage, making it impossible to store the item in a stable state.

[0075] According to this embodiment, in addition to achieving the same effect as the first embodiment, since it is the top surface of the film gusseted packaging bag 1'p, and openings 121 are formed on the front and back sides divided by the handle 11h, even when the handle 11h is folded to either the front or back side of the top surface, air can be reliably vented through the openings 121 on either the front or back side.

[0076] <Third Implementation Method>

[0077] The opening 121 is not limited to being formed on the top surface of the sanitary tissue packaging 1, but can be formed on the front, back, or side. That is, instead of the structure described in the first or second embodiment of the present invention where the opening 121 is formed on the top surface, a structure in which the opening 121 is formed on the front, back, or side can be adopted. In this case, similar to the sanitary tissue packaging 1 and sanitary tissue packaging 1' described in the first or second embodiment of the present invention, the opening 121 is preferably formed to be able to be opened or closed by a slit flap, thereby preventing foreign matter such as dust from entering the sanitary tissue packaging 1" while more effectively venting air out of the sanitary tissue packaging 1".

[0078] Figure 8This is an overall perspective view of the sanitary tissue paper product packaging body 1" according to the third embodiment of the present invention. Elements having the same function among the various elements constituting the sanitary tissue paper product packaging body 1" according to this embodiment are labeled with the same symbols as in the second embodiment of the present invention, and their descriptions are omitted. For example... Figure 8 As shown, on the film-supported packaging bag 1”p of the sanitary tissue paper product packaging body 1”, two pairs of openings 121 are formed on the upper part of the pair of front and back portions 15 of the sanitary tissue paper product packaging body 1”, and one pair is formed on the upper part of the pair of left and right side portions 16. Regarding the number and location of the openings 121, one can be formed on each of the pair of front and back portions 15, or they can be formed on any of the pair of front and back portions 15 and the pair of left and right side portions 16, and various styles can be adopted. With this structure, unnecessary expansion of the film-supported packaging bag 1”p of the sanitary tissue paper product packaging body 1” can be prevented. It should be noted that, in this invention, it is also permissible to add a structure with an opening 121 formed on the front, back, or side of the structure already having an opening 121 formed on the top surface, as described in the first or second embodiment of this invention. In these cases, similar to the sanitary tissue packaging 1 and sanitary tissue packaging 1' described in the first or second embodiment of this invention, the opening 121 is preferably formed to be able to be opened or closed by a slit flap, thereby preventing foreign matter such as dust from entering the sanitary tissue packaging 1" while allowing air to be vented out of the sanitary tissue packaging 1".

[0079] <Other>

[0080] This invention is not limited to the embodiments described above and the variations mentioned herein. Appropriate changes and modifications can be made without departing from the technical concept of this invention.

[0081] Furthermore, in the second and third embodiments described above, openings 121 are formed on the top surface of the film-supported packaging bag 1p, on the front and back sides separated by the handle portion 11h. The handle portion 11h may also be omitted. As described above, one or more openings are provided on the top surface and / or the front, back, and sides of the film-supported packaging bag 1p. In this case, when multiple sanitary tissue packaging bodies 1 are packed into a carton in a subsequent process after manufacturing the sanitary tissue packaging body 1, this packing operation allows for the simultaneous degassing of the sanitary tissue packaging bodies 1 and the stable, gapless packing of the multiple sanitary tissue packaging bodies 1 into the carton. In particular, by setting the carton to a smaller size to ensure stable stacking, and by compressing multiple sanitary tissue packaging bodies 1 while packing them into the carton, the sanitary tissue packaging bodies 1 can be degassed while being stably packed into the carton without gaps. Furthermore, in this case, if the opening is provided on two adjacent sides of the film-supported packaging bag 1p, for example, on the top and front surfaces of the film-supported packaging bag 1p, then when multiple tissue paper product packaging bodies 1 are compressed and loaded into a carton, regardless of the compression direction, the tissue paper product packaging bodies 1 can be vented while being stably loaded into the carton without gaps. In these cases, similar to the tissue paper product packaging body 1 according to one embodiment of the present invention described above, the opening is preferably formed so that it can be opened or closed by a slit flap, thereby preventing foreign matter such as dust from entering the tissue paper product packaging body 1 while venting air out of the tissue paper product packaging body 1.
