Description

  The present invention relates to a continuous package of absorbent articles.

Conventionally, absorbent articles such as sanitary napkins and panty liners (orimono sheets) are folded together with packaging materials, individually packaged, and marketed.
As an example of this packaging form, for example, in the ASEAN countries, a plurality of continuous packaging bodies in which absorbent articles (sanitary napkins) are individually packaged by an exterior sheet are formed as continuous packaging bodies that can be separated for each packaging body. Yes (see Patent Document 1 or 2). A seal processing portion and a cut line portion are arranged at a connection portion between the package bodies, and individual package bodies are cut off at the cut line portion. Each separated package is opened at an opening separation line portion on its outer surface, and an absorbent article (a sanitary napkin) is taken out. At that time, the tearing-off line part is torn to the left and right.

  Moreover, as for the continuous package body described in patent document 2, each package body is being fixed to the inner surface of the exterior sheet | seat by at least one part of an absorbent article. Specifically, each packaging body has the absorbent article and the exterior sheet along the direction orthogonal to the continuous direction in which the packaging body is continuous, with the back surface of the absorbent article and the inner surface of the exterior sheet facing each other. Are formed by being folded together. In the overlapping region where both ends of the exterior sheet are folded, a seal processing portion for dividing the napkin into one is processed by processing such as heat seal fusion. The sealing portion is perforated, and a cut line portion is formed with perforations for separating the package one by one.

In the continuous package described in any of Patent Document 1 and Patent Document 2, although a cut line portion between adjacent packages is described, details of the separation strength are not described. In the drawing described in Patent Document 1, it can only be seen that it is composed of broken lines having a constant interval and width.
In the continuous package described in Patent Document 2, although the cut line portion is formed by perforations, details are not disclosed.
Such a continuous package is sold by being hung from a high position in a store. Therefore, the operation which cuts off the desired number of package bodies is needed at the time of sale. When separating the continuous package into the desired number of packages, if the separation guide is uniformly formed in the width direction, the separation strength required for separation of the exterior material is too strong, that is, the force strong against separation. If this is necessary, it may cause tearing of the outer packaging material or tearing of the unsealing guideline for unpacking the individual packaging, and there is room for improvement. On the other hand, when the separation strength is set low considering the ease of separation, when the product is hung at the storefront or when the purchaser applies force to separate the desired number of packages, It becomes easy to cut the package of the part from the unintentional separation guide part.
In particular, since the continuous package disclosed in Patent Document 2 has a so-called three-fold structure, the number of exterior materials that are overlapped differs depending on the region, and the separation guiding portion is formed uniformly in the width direction. In some cases, it was more difficult to control the separation strength.

  [Technical Field] The present invention relates to providing a continuous package of an absorbent article that is difficult to be inadvertently separated when sold by being hung at a store, and that can be easily separated at a desired location at the time of sale.

  The present invention is a continuous package of absorbent articles in which a vertically long absorbent article is packaged with an exterior material and is continuously arranged in the first direction, and between the adjacent individual packages. The separation region disposed on the folded exterior material includes a separation guide portion along a second direction intersecting the first direction, and the separation guide portion has a separation strength on the center side in the second direction. Provided is a continuous package of absorbent articles that are the same or weaker than the separation strength on the outer edge side.

  According to the continuous packaging body of the absorbent article of the present invention, at the time of over-the-counter sales, separation of the packaging body at an unintended location is suppressed, and each packaging body can be easily separated and sold / purchased. be able to.

A preferred embodiment (first embodiment) of a continuous package of absorbent articles according to the present invention will be described below with reference to FIGS. 1 to 3.
In this specification, in a state where the garment is worn, the surface in contact with the wearer is referred to as a wearer contact surface or a skin contact surface, which is a relatively opposite surface, that is, a side in contact with the worn garment. The surface is called a clothing contact surface or a non-skin contact surface. Further, the surface closer to the wearer is referred to as the wearer contact surface side or the skin contact surface side, and the surface closer to the clothing is referred to as the clothing contact surface side or the non-skin contact surface side.

As shown in FIG. 1, the continuous package 30 has a plurality of the packages 20 continuously in the first direction. The number of the wrapping bodies 20 is not limited to the three wrapping bodies shown in the illustrated example, and may be larger. Moreover, a 1st direction means the direction where the package 20 continues continuously. That is, it is a continuous package 30 in which the individual packages 20 are continuously arranged. The second direction intersecting with the first direction, that is, the second direction is the width direction of the continuous package 30. In the width direction, a side sealing portion 27 serving as a separation region for separating the individual packaging bodies 20 is disposed. The individual packaging bodies 20 can be freely separated by a separation guide portion 28 disposed in the side sealing portion (separation region) 27.
The separation guiding portion 28 includes a portion where the separation strength on the center side in the second direction is the same or weaker than the separation strength on the outer edge side. In the present embodiment, the separation guiding portion 28 has the same or weaker separation strength at the center side in the second direction than the outer edge side, and is preferably weaker. In this embodiment, the outer edge side is an area including the side edges in the width direction of the continuous package, and includes an outer area in the second direction including an area corresponding to the start of separation when performing a separation operation at the time of over-the-counter sales. is there. Further, the center side refers to a portion on the inner side in the second direction from the outer edge side, and in the present embodiment, the center side includes a region where the number of overlapping of the exterior material 11 is larger than that of the outer edge side, and is usually separated from the outer edge side. There is a tendency for strength to increase. Details of the separation guiding unit 28 will be described later.
The separation strength is measured as follows. The exterior material 11 is cut out with a width of 20 mm so that the packaging body 20 is strip-shaped in the first direction in which the package bodies 20 are continuously connected, and the separation guide portion 28 is located across the center. Next, in an environment of 20 ° C. and 65% RH, using a Tensilon tensile tester (for example, product name “RTA-100” manufactured by Orientec Co., Ltd.) at a peeling rate of 300 mm / min, 180 ° direction Pull on. At that time, the average of the maximum value of 5 points is taken, and further, the average of 3 samples is taken, and this is separated and used as the separation strength of the guiding portion.
Each package 20 is provided with an opening guide portion 25 in the first direction.

  First, the individual packaging bodies 20 of the continuous packaging body 30 and the absorbent article 10 packaged in the packaging body 20 will be described below.

  As shown in FIG. 2, the vertically long absorbent article 10 wrapped in the package 20 of the present embodiment is, for example, a sanitary napkin (hereinafter referred to as a napkin). Hereinafter, the napkin package will be described in detail. Therefore, the vertically long absorbent article 10 will be described as a napkin 10. Further, the longitudinal direction of the napkin 10 is the longitudinal direction. Hereinafter, the vertical direction refers to the vertical direction of the napkin 10 or a direction parallel to this direction.

  As shown in FIG. 3, the napkin 10 includes a liquid-permeable top sheet 1 disposed on the skin contact surface side, a liquid-impermeable back sheet 2 disposed on the non-skin contact surface side, and a surface. A vertically long main body 4 having an absorbent body 3 having a liquid retaining property interposed between the sheet 1 and the back sheet 2, and wings 5 extending outwardly on both sides of the main body 4 are provided. .

  Further, as shown in FIG. 2, a slip stopper 13 for fixing the napkin 10 to the clothing is disposed on the clothing contact surface of the back sheet. A release sheet 14 detachable from the misalignment stopper 13 is disposed so as to cover the misalignment stopper 13. Further, a release sheet fixing portion 15 for fixing the release sheet 14 is disposed on the inner surface of the exterior material 11, and the exterior material 11 is fixed to the release sheet 14. Therefore, the fixing portion 12 includes a slippage preventing portion 13 that fixes the clothing contact surface 10sw of the napkin 10 to the clothing, and a release sheet fixing portion 15 that fixes the release sheet 14 to the inner side surface of the exterior material 11.

The package 20 of the absorbent article is formed by folding the exterior material 11 together with the napkin 10 as the absorbent article in the vertical direction and sealing the exterior material 11. Thus, the napkin 10 is individually packaged, and the clothing contact surface 10sw of the napkin 10 is fixed to the inner side surface of the exterior material 11 by the fixing portion 12. The term “fixed” as used herein refers to a state in which the clothing contact surface of the napkin 10 and the inner surface of the exterior material 11 do not move relative to each other in the packaged state. It may be indirectly fixed via the member. As an example in which both are indirectly fixed, a case where the both are fixed via a release sheet 14 can be cited. In this case, as a fixing means between the members, a release sheet fixing means 15 which is a fixing means between the release sheet 14 and the exterior material 11, and a clothing contact surface 10 sw of the release sheet 14 and the napkin 10. There is a misalignment stop 13 which is a fixing means. When both are overlapped in plan view, the overlapping portion of both is the fixing portion 12, and when both are not overlapping, the fixing portion 12 is the release sheet fixing portion 15. On the other hand, when there is no release sheet 14 and the garment contact surface 10sw of the napkin 10 is directly fixed by the shift stopper, the shift stopper 13 is the fixing portion 12. The napkin 10 and the release sheet 14 are in a fixed state that can be peeled off. The release sheet 14 and the exterior material 11 are fixed in a stronger fixed state than the napkin 10 and the release sheet 14, for example, preferably in a fixed state that is difficult to peel off. The package 20 is folded at least twice in the longitudinal direction of the napkin 10 with the wearer contact surface 10 sm side of the napkin 10 facing inside. In the example of illustration, it is folded twice by folding at two places, the 1st folding part L1 and the 2nd folding part L2.
In the present specification, “peeling” means that it can be easily picked up with a finger and “adhesion” described later means that it cannot be easily picked up with a finger.

When the exterior material 11 is folded together with the release sheet 14 and the napkin 10, the exterior material 11 has a size that includes them. Further, in the folded state, the one end portion 11a side of the exterior material 11 in the vertical direction is arranged to extend outward from the one end portion 10a of the napkin to form an exterior material extension region.
The exterior material 11 is made of a material in which the first direction (longitudinal direction) is more easily torn than the second direction (lateral direction). For this reason, when opening in order to take out the napkin 10 from the package 20, it is easy to open along the 1st direction. Further, the tear strength of the exterior material 11 is higher in the tear strength in the first direction of the exterior material 11 and the local separation strength of the separation guide portion 28 in the separation region.
Thus, even if it is a case where the 1st direction of the exterior material 11 consists of a material which is easy to tear than the 2nd direction, when cut | disconnecting each packaging body 20, the exterior packaging material 11 of the other adjacent packaging body 20 is torn. There will be no disconnection. Moreover, even if the opening guide part 25 along the first direction on the center side is arranged, the opening guide part 25 is not cleaved, and the separating operation can be performed.

  As the material of the exterior material 11, those conventionally used for packaging absorbent articles such as napkins can be used without particular limitation. Resin films such as polypropylene, polyester, polyethylene, polyvinyl alcohol, and the like can be used, and can be appropriately selected and used. In the case of non-woven fabrics, composite non-woven fabrics of spunbonded non-woven fabric (S) and melt-blown non-woven fabric (M) (SM, SMS, SMMS, etc.) in terms of sheet strength, liquid resistance (resistance to hot melt oozing) and sealing properties ) Is preferred. From the viewpoint of performing clear printing directly on the packaging material 11, a film material or a laminate structure of the film is also preferably used. In particular, the opening strength of the opening guide portion 25 can be appropriately reduced by using an oriented material whose tearing strength in the continuous direction of the continuous package 30 (see FIG. 1) is lower than that in the width direction, and easy to open. Can increase the sex.

  The packaging body 20 is provided with a sealing portion 26 along the first direction on the center side, and side sealing portions 27 along the second direction are arranged at both end portions in the first direction. The body 20 is sealed. The side sealing portion 27 has a region where two exterior members 11 are overlapped on the outer edge side in the second direction, and a region where three exterior members 11 are overlapped on the center side in the second direction. Sealing of the overlapped exterior material 11 is performed by means such as adhesion using a coating film of a hot melt adhesive, bonding by heat fusion of the exterior materials 11 or embossing, and the like.

The package 20 of the present embodiment has a so-called three-fold structure, and the first exposed region 21 where the region including the one end portion 11a of the exterior material becomes the outer surface of the package 20, the first folded portion L1, and the first fold portion L1. A central region 23 between the second fold portion L2 and a region 22 including the other end portion 11b of the exterior material, which is a portion located immediately inside the first exposed region 21 and extending from the second fold portion L2. Yes. And the area | region 22 containing the other end part of exterior material overlaps with the 1st exposure area | region 21 by planar view, forms the overlap area 24, and is provided with the inner side overlap area | region 24a located in the inner side of a 1st exposure area | region regarding the thickness direction. Yes.
The exterior material 11 in the area of the first exposed area 21 in the overlapping area 24 is provided with an opening guide portion 25 that allows the package 20 to be opened. More specifically, the opening guide portion 25 is formed in an exterior material extension region in which the one end portion 11 a side of the exterior material 11 extends outward from the one end portion 10 a of the napkin 10. And the fixing | fixed part 12 provided in the inner side overlap area | region 24a which exists just inside the 1st exposed area | region 21, and the opening guide | induction part 25 are arrange | positioned so that it may overlap in planar view. In the packaging body 20 having the three-fold structure according to the present embodiment, the packaging body 20 overlaps with the fixing portion 12 disposed in the region 22 including the other end of the packaging body 20 in a plan view.
Furthermore, the end portion of the first exposed region 21 and the region 22 including the other end portion are sealed by the sealing portion 26 and further sealed by the side sealing portion 27 described above, whereby the packaging body 20 is configured. ing. The package sealing portion 26 is arranged on the outer side in the longitudinal direction than the opening guide portion 25.

  The opening guide portion 25 is arranged on the outer side in the vertical direction from one end portion of the napkin 10 in the first exposed region 21 in a state where the napkin 10 is folded. The opening guide portion 25 includes a perforation lined in a line, an assembly of perforations lined in a predetermined width, and a cut line that does not cut in the thickness direction of the exterior material 11 arranged in a line. An assembly of cuts that do not lead to cutting in the thickness direction of the exterior material 11 that is linearly arranged with a predetermined width, a groove in which the tensile strength of the exterior material 11 is weakened linearly, and a tensile strength of the exterior material 11 that is dotted A group of holes weakened in a straight line with a predetermined width. The outer packaging material 11 is broken from the opening guidance portion 25 by pressing or pulling the outer packaging material 11 on both sides of the opening guidance portion 25 with a finger or the like, and the package 20 is opened. Any configuration may be used as long as dust or the like does not enter the interior and the cleanliness of the interior can be maintained.

  The misalignment stopper 13 is disposed on the non-skin contact surface side of the napkin 10 and is used when the napkin 10 is attached to the shorts. As the hot melt adhesive, rubber-based, olefin-based, ethylene vinyl acetate (EVA) -based, or the like can be used. The misalignment stopper 13 may be a so-called solid coating that is continuously applied, such as a planar shape, but in consideration of the adhesive remaining on the shorts in the coated area and the ease of taking out from the exterior material 11 It is preferable that the coating is intermittently applied. Examples of the intermittent application form include a spiral shape, a stripe shape extending in the width direction or the longitudinal direction, an Ω-shape, a dot shape, and the like. The misalignment stopper 13 is positioned substantially in the center in the front-rear and left-right direction of the main body on the non-skin contact surface side of the napkin 10, has a width of 35 mm to 70 mm, and a length of 65% or more with respect to the length of the napkin 10. A range of 95% or less is preferred. Further, the misalignment stopper 13 includes all the adhesive portions of the misalignment stopper 13 from the viewpoint of preventing the misalignment and misalignment of the napkin 10 in use, and has a width and length that is substantially the same as or slightly smaller than the napkin 10 in plan view. Good.

  The misalignment stopper 13 may exist from the center in the vertical direction of the napkin 10 to the vicinity of the tip of the napkin 10 beyond the first fold L1 and the second fold L2. The release sheet 14 covering the misalignment stopper 13 has a size that can cover the misalignment stopper 13, and is used by being bonded to the exterior material 11 by the release sheet fixing section 15.

  The release sheet fixing portion 15 uses a hot melt adhesive to bond and fix the release sheet 14 and the exterior material 11. The release sheet fixing portion 15 is made of, for example, a hot melt adhesive coating film. As this hot melt adhesive, rubber-based, olefin-based, EVA-based and the like can be used.

A release sheet 14 is disposed to protect the misalignment stopper 13 on the product body side. The release sheet 14 can be made of the same material as that of a general napkin release sheet. Specifically, the coating amount of glassine paper, polyethylene film, silicone treatment agent is, for example, 0.1 to 5 g / release-treated fine paper of m ^2, composites thereof, and the like. This peeling treatment can be performed using a known method. Furthermore, the release sheet 14 may be of any size as long as the outer shape covers the misalignment stopper 13, and the shape is not limited.

The sealing part 26 is made of, for example, a hot melt adhesive coating film. As this hot melt adhesive, rubber-based, olefin-based, EVA-based and the like can be used. In addition, adhesion by heat melting may be used.
The sealing portion 26 is preferably colored, and more preferably a colored hot melt. By coloring, the exterior material edge part of a 1st exposure area | region can be specified, and there exists an effect that it is easy to appeal to a user that the sealing degree as a product is ensured. There are systems in which ink or pigment is added as the colored hot melt, but a hot melt component that has a large absorption spectrum characteristically in the original visible absorption region may be selected. For example, it is conceivable to use a yellowish hot melt by means such as lowering the hydrogenation rate of a styrene-butadiene-styrene block copolymer which is one main component of the hot melt.

  The shape in the case of using a hot melt material for the sealing portion 26 may be any shape, and is often a straight line (coater coating) having a certain width, but spiral coating, summit coating, Ω coating, etc. It may be a pattern composed of curves. A pattern composed of curves is preferable in that it can be efficiently bonded with a small amount.

  In the continuous package 30 of the present embodiment, the separation guide portion 28 has the same or weaker separation strength on the center side in the second direction than the separation strength on the outer edge side. Even if many layers are stacked or there is a sealing material, the package 20 that is separated from the outer edge portion and separated along the guide portion 28 is smoothly separated without applying a large force on the center side. Therefore, even if the individual unpacking guide line 25 along the first direction is arranged on the center side, the unwrapping guide line 25 is cut off without tearing, and the individual packaging bodies 20 and 20 are separated along the guide line. It becomes easy to separate. In addition, the separation strength on the center side is designed to be weak enough to easily separate the packages, and the separation force on the outer edge side can be increased to such an extent that it cannot be broken during store display. In this way, in the separation region (side sealing portion 27) between the packaging bodies 20, by separating the strength difference due to the difference in the overlap of the exterior material 11 and setting the separation strength of the guide portion 28 as described above, smoothness is achieved. Can be realized. Thereby, when the individual packaging bodies 20 are cut off, the outer packaging material 11 of the other adjacent packaging bodies 20 is not torn. This effect is particularly effective when the exterior material is made of a material that is easier to tear in the first direction than in the second direction.

Further, a sealing agent (not shown) may be disposed in the first direction including the separation region (side sealing portion 27) in the central region in the second direction of the exterior material 11.
In these cases, when the individual packaging bodies 20 are cut off by the same action as described above, the outer packaging material 11 of the other adjacent packaging bodies 20 is not torn, and the opening guide line along the first direction of the center portion Even if 25 is arranged, it is possible to easily realize the separation operation along the separation guide portion 28 without tearing the opening guide line 25.

  Next, the separation guiding unit 28 will be described below. As described above, the separation guiding portion 28 has the same or stronger separation strength on the outer edge side in the second direction than the separation strength on the center side.

  As shown in FIG. 4, the separation guide portions 28 are arranged in the second direction, which is the width direction of the continuous package 30 (see FIG. 1), and the breaking portions 28 c and the engaging portions 28 b are alternately arranged. . The outermost edge on both sides in the second direction is provided with a breaking portion 28c, and the length L1 of the engaging portion 28b1 arranged next is between the breaking lines 28c and 28c in the separation guide portion 28 on the center side. It is larger than the length L2 of the engaging portion 28b2, and the separation strength is stronger than the center side. As a result, the continuous packaging body 30 is shaken at the time of over-the-counter sales, and a force is applied to the separation guide wire 28, so that it is easy to suppress separation of the packaging body at an unintended location. From the standpoint of easily exerting this effect with certainty, the length L1 is preferably 1.5 times or more, more preferably 3 times or more, and even more preferably 5 times or more with respect to the length L2. The length L1 is preferably 10 times or less, more preferably 8 times or less, and still more preferably from the viewpoint of facilitating separation of the center side breaking portion 28c from the outer edge side breaking portion 28c. Is preferably 6 times or less. In the present embodiment, the length of the engagement portion 28b2 on the center side is equal in the second direction. In the present embodiment, the length L1 of the engaging portion 28b1 is set to be longer than the length L2 of the engaging portion 28b2 at the central portion only at the outermost edge portion, but this is not a limitation, and at several locations on the outer edge side, An engagement portion 28b1 longer than the engagement portion 28b2 on the center side may be provided to increase the separation strength.

  In addition, it is preferable that the rupture portions 28c are arranged at both ends of the separation guide portion 28 in the second direction because the separation operation is easily performed. The length of the fracture portion 28c is, for example, preferably 0.5 mm or more, more preferably 1 mm or more, and further preferably 2 mm or more. And from a viewpoint that the external appearance at the time of store sales is not impaired, Preferably it is 10 mm or less, More preferably, it is 5 mm or less, More preferably, it is 3 mm or less.

  In addition, the engaging portions 28b1 may be disposed at both ends of the separation guide portion 28 in the second direction. In this case, the length of the engaging portion 28b1 is larger than the length of the engaging portions 28b at the portions other than both ends. When it is short, it is preferable from the viewpoint of stably breaking a desired place when starting the separation operation. For example, it is preferably 3 mm or less, more preferably 1 mm or less, and still more preferably 0.5 mm or less.

  On the other hand, the length of the engaging portion 28b2 is shorter on the center side than the engaging portion 28b1 on the outer edge side, and the breaking portion 28c is denser than the outer edge side, so that the detachment operation is easy. Therefore, it is easy to cut off smoothly even at the central portion where the outer packaging materials 11 overlap and the number of the outer packaging materials 11 is larger than that of the outer edge. The ratio of the length of the fracture portion 28c to the length of the engagement portion 28b2 on the center side is preferably 1/5 or more and 5 or less, and particularly preferably 1/2 or more and 2 or less.

The configuration of another separation guide portion 28 will be described below.
As shown in FIG. 5, the separation guide portion 28 is arranged in the second direction, which is the width direction of the continuous package 30 (see FIG. 1), and the breaking portions 28 c and the engaging portions 28 b are alternately arranged. . The outermost edge portions on both sides in the second direction are provided with the breaking portions 28c, and the length S1 of the breaking portion 28c1 disposed next with the engaging portion 28b interposed therebetween is the breaking portion 28c2 of the separation guide portion 28 on the center side. Is shorter than the length S2, preferably 1/2 or less, more preferably 1/4 or less. It is assumed that the length of the engaging portion 28b is equal in the second direction.
Since the number of the engaging portions 28b per unit length in the outer edge side region is larger than the number per unit length of the engaging portions in the central side region, the separation strength is stronger on the outer edge side than on the central side.

Further, the configuration of another separation guide unit 28 will be described below.
As shown in FIG. 6, the separation guide portion 28 is arranged in the second direction, which is the width direction of the continuous package 30, and the breaking portions 28 c and the engaging portions 28 b are alternately arranged. A separation region where the separation guide portion 28 is disposed is a side seal portion 27.
A separation guide portion 28 is disposed on the side seal portion 27 that seals the exterior material 11 of the package 20 along the second direction, and the separation guide portion 28 is not overlapped with a part of the side seal portion 27 in the outer edge side region. A region 29 is provided. That is, the region 29 is a region that is disposed in the side seal portion 27 on the outer edge side and does not have the side seal portion 27.
Further, the shape of the side seal portion 27 may be a rectangle shown in FIG. 6B or a shape in which both ends shown in FIG. It may be a semi-ellipse as shown in d) or a circle or the like. That is, various shapes can be employed.
In the above configuration, in the outer edge side region, a part of the side seal portion 27 has a region 29 that does not overlap with the separation guide portion 28. When a strong force is applied in the first direction, which is the continuous direction of the continuous package 30, in the non-overlapping region 29, each sheet of the exterior material 11 is not bonded, so each sheet is independently It will receive stress. Therefore, it is possible to temporarily prevent the stress from concentrating on the fracture portion 28c at a stretch, and as a result, the outer edge side has a higher separation strength than the central side. This effect is expected to be higher by using a stretchable material for the exterior material 11.

The separation guide portion 28 preferably has the following shape.
For example, as shown in FIG. 7A, the rupture portions 28c and the engagement portions 28b are alternately arranged, and the rupture portions 28cs having a shorter length than the center side are arranged on the outer edge side. The length of the fracture portion 28cs is preferably 1 mm or more, more preferably 4 mm or more, and even more preferably 6 mm or more from the viewpoint of easy separation.
