Description

本発明は、吸収性物品の包装体に関する。   The present invention relates to a package for absorbent articles.

生理用ナプキン、パンテイライナー、軽失禁パッド、ライナー等の吸収性物品は、衛生的に保管、使用するために、通常、包装シートにより１枚ずつ個別に包装されている。そして、使用者は、使用する際に、該包装シートから吸収性物品を取り出して、装着する。   Absorbent articles such as sanitary napkins, panty liners, light incontinence pads, and liners are usually individually packaged one by one with a packaging sheet for hygienic storage and use. And a user takes out an absorptive article from this packaging sheet, and uses it, when using it.

例えば、下着に装着する前記吸収性物品は、下着側のバックシートに粘着層が設けられ、さらに、その粘着層には粘着層を保護する剥離紙が設けられ、その剥離紙と包装シートとが剥離不能に接着された状態で、吸収性物品本体の長手方向と直角方向に３つ折り又は２つ折りされ、包装シートの両側端縁部を熱シールにて固着して、包装されている。 For example, in the absorbent article to be attached to underwear, an adhesive layer is provided on the back sheet on the underwear side, and further, a release paper for protecting the adhesive layer is provided on the adhesive layer, and the release paper and the packaging sheet are In a state where the absorbent article main body is bonded in a non-peelable state, the absorbent article main body is folded in three or two in the direction perpendicular to the longitudinal direction, and both side edges of the packaging sheet are fixed by heat sealing and packaged.

そして、使用者が、包装体の開封口に貼着された止着テープをつまんで、包装体を開封すると、吸収性物品に設けられた前記剥離紙は、包装シートと一体的にめくられて、前記粘着層が露出するので、該吸収性物品を下着に貼りつけて、使用することができる。
また、包装体の開封口には前記止着テープを設けず、開封口に指を入れるなどして開封し、前記と同様に吸収性物品を取り出して使用する場合もある。 Then, when the user pinches the fastening tape attached to the opening of the packaging body and opens the packaging body, the release paper provided on the absorbent article is integrated with the packaging sheet. Since the adhesive layer is exposed, the absorbent article can be attached to an undergarment and used.
In some cases, the opening of the package is not provided with the fastening tape, and is opened by inserting a finger into the opening, and the absorbent article is taken out and used in the same manner as described above.

吸収性物品の包装体の構造に関して、特許文献１には、個別包装の長手方向端部の開封部に止着テープを設け、包装シートを特定の材料とすることにより前記止着テープをはがして、開封を容易にする方法が開示されている。また、特許文献２には、包装シートの長手方向端部に凸部のつまみを設けて、個別包装の開封を容易にする発明が開示されている。 Regarding the structure of the package of absorbent articles, in Patent Document 1, a fastening tape is provided at the opening portion of the longitudinal end portion of the individual packaging, and the fastening tape is peeled off by using a packaging sheet as a specific material. A method for facilitating opening is disclosed. Patent Document 2 discloses an invention that makes it easy to open an individual package by providing a convex knob at the longitudinal end of the packaging sheet.

しかしながら、包装シートの端縁部に貼着された止着テープは、つまみにくく、吸収性物品本体を取り出すのが困難であるという問題があった。また、包装体の開封口に止着テープを設けない形式の場合、開封口がわかりにくい上、開封口の一端がつまみにくい問題があった。さらに、トイレ等の比較的暗い空間で吸収性物品の開封作業を行おうとすると、吸収性物品に対する視認性の低さが加わり、なおさらこの動作は困難であった。   However, the fastening tape adhered to the edge of the packaging sheet is difficult to pinch and has a problem that it is difficult to take out the absorbent article main body. Further, in the case of the type in which the fastening tape is not provided at the opening of the package, there is a problem that the opening is difficult to understand and one end of the opening is difficult to pinch. Furthermore, when attempting to open the absorbent article in a relatively dark space such as a toilet, the visibility of the absorbent article is added, and this operation is more difficult.

そこで、本発明は、吸収性物品の包装体の開封口をつまみ易く、開封し易い吸収性物品の包装体を提供することを目的とする。   Then, an object of this invention is to provide the package body of the absorbent article which is easy to pinch the opening of the package body of an absorbent article, and is easy to open.

本発明における吸収性物品の包装体１０の１形態について、図１ないし図４にて説明する。該吸収性物品の包装体１０は、吸収性物品１と、包装シート２を備える。吸収性物品１は、肌と接触する側から順に、液透過性のトップシート（図示せず）、液保持性の吸収体（図示せず）、液不透過性のバックシート（図示せず）が配置されている。バックシートには下着と接触する面に粘着層(図示せず)が設けられ、さらに、その粘着層には粘着層を保護する剥離紙(図示せず)が設けられ、その剥離紙と包装シート２とが剥離不能に接着された状態で、吸収性物品１の長手方向と直角方向に３つ折りされ、包装シート２の両側端縁部２１を熱シールにて固着して、包装されている。 One form of the package 10 of the absorbent article in this invention is demonstrated in FIG. The absorbent article packaging body 10 includes an absorbent article 1 and a packaging sheet 2. The absorbent article 1 has a liquid-permeable top sheet (not shown), a liquid-retaining absorbent body (not shown), and a liquid-impermeable back sheet (not shown) in order from the side in contact with the skin. Is arranged. The back sheet is provided with an adhesive layer (not shown) on the surface in contact with the underwear, and the adhesive layer is further provided with a release paper (not shown) for protecting the adhesive layer. The release paper and the packaging sheet 2 is bonded in a non-peelable manner and is folded in three in a direction perpendicular to the longitudinal direction of the absorbent article 1, and the both side edge portions 21 of the packaging sheet 2 are fixed by heat sealing and packaged.

開封口２４は、包装シート２の長手方向の端縁部と、もう一方の端縁部とが重なり合って形成されており、各端縁部は、吸収性物品１の長手方向の前側の端縁部である前端縁部２２と、後ろ側の端縁部である後端縁部２３と呼ぶ。高摩擦材層３は、開封口２４近辺の前端縁部２２に形成されている。また、高摩擦材層３の後ろ側方向近傍で、包装シートの重なり合っている部分には、長手方向と直角方向にライン上のホットメルト接着剤を塗布して包装体２が封止されている（図示せず）。使用者は、包装シート２と高摩擦材層３との摩擦力の差を触感で認識し、開封口２４の位置を容易に判断することができ、前端縁部２２と後端縁部２３の間に指を差し込んで、包装体２を開封する。高摩擦材層３は、図４(ａ)に示すように、開封口２４の先端部２５に形成することが好ましい。また、図４（ｂ）に示すように、開封口２４の先端部２５を覆うように、高摩擦材層３を形成してもよい。さらに、図４（ｃ）に示すように、高摩擦材層３は、吸収性物品の包装体１０を形成した際に、包装シート２の後端縁部２３に、前端縁部２２と重ならない位置に形成してもよい。この開封作業により、剥離紙は包装シート２と一体的にめくられ、結果、粘着層が露出するので、使用者は、吸収性物品１を下着に貼りつけて、使用することができる。 The opening 24 is formed by overlapping an end edge in the longitudinal direction of the packaging sheet 2 and the other edge, and each end edge is an end edge on the front side in the longitudinal direction of the absorbent article 1. These are referred to as a front edge 22 that is a part and a rear edge 23 that is a rear edge. The high friction material layer 3 is formed on the front edge portion 22 near the opening 24. Further, in the vicinity of the rear side direction of the high friction material layer 3, the package 2 is sealed by applying a hot melt adhesive on the line in a direction perpendicular to the longitudinal direction on the overlapping portion of the packaging sheet. (Not shown). The user can recognize the difference in frictional force between the packaging sheet 2 and the high friction material layer 3 by tactile sensation, and can easily determine the position of the opening 24. The package 2 is opened by inserting a finger between them. The high friction material layer 3 is preferably formed at the front end portion 25 of the opening 24 as shown in FIG. Moreover, as shown in FIG.4 (b), you may form the high friction material layer 3 so that the front-end | tip part 25 of the opening 24 may be covered. Furthermore, as shown in FIG.4 (c), when forming the package 10 of an absorbent article, the high friction material layer 3 does not overlap with the front-end edge part 22 at the rear-end edge part 23 of the packaging sheet 2. As shown in FIG. You may form in a position. By this opening operation, the release paper is turned together with the packaging sheet 2 and, as a result, the adhesive layer is exposed, so that the user can use the absorbent article 1 by attaching it to the underwear.

本発明の吸収性物品１としては、特に制限はないが、例えば、生理用ナプキン、パンテイライナー、軽失禁パッド、ライナー等をあげることができる。また、吸収性物品１を構成するトップシート、吸収体、バックシート、粘着層及び剥離紙に関して、構成成分及び位置等は、特に限定されず、適宜選択することができる。 Although there is no restriction | limiting in particular as the absorbent article 1 of this invention, For example, a sanitary napkin, a panty liner, a light incontinence pad, a liner etc. can be mention | raise | lifted. Moreover, regarding the top sheet, the absorbent body, the back sheet, the pressure-sensitive adhesive layer, and the release paper constituting the absorbent article 1, the constituent components, positions, and the like are not particularly limited and can be appropriately selected.

Materials and the like can be used. Moreover, the peeling process by a silicon | silicone etc. can also be performed inside the packaging sheet 2 which contact | connects the absorbent article 1. FIG. The basis weight of the wrapping sheet 2 is not particularly limited, in terms of strength and workability, preferably 15 to 30 g / m 2, further 20-25 g / m 2 is preferred.

本発明の高摩擦材層３は、包装シート２との摩擦力の差により、開封口を識別するものであり、包装シート２の表面に形成する。高摩擦材層３の形成方法としては、例えば、基材に高摩擦材を塗工した部材を、ホットメルト等の接着剤により包装シート２の表面に固着する、包装シート２に高摩擦材を直接塗工する、あるいは、開封口２４近傍の包装シート２にエンボス処理を行う等があげられる。 The high-friction material layer 3 of the present invention is for identifying the opening by the difference in frictional force with the packaging sheet 2 and is formed on the surface of the packaging sheet 2. As a method for forming the high friction material layer 3, for example, a member obtained by applying a high friction material to a base material is fixed to the surface of the packaging sheet 2 with an adhesive such as hot melt. For example, direct coating or embossing is performed on the packaging sheet 2 near the opening 24.

高摩擦材層３の基材としては、特に制限はなく、例えば、紙、ポリエチレン、ポリプロピレン、ポリエステル、ポリビニルアルコール等の樹脂フィルム、スパンボンド不織布、メルトブローン不織布及びスパンボンド／メルトブローン／スパンボンドを積層した複合不織布、あるいはこれらの複合材料等をあげることができる。高摩擦材層３の基材は、包装シート２と同じ材料を用いても、異なる材料であっても、特に制限なく用いることができる。 The base material of the high friction material layer 3 is not particularly limited. For example, paper, polyethylene, polypropylene, polyester, polyvinyl alcohol, or other resin films, spunbond nonwoven fabric, meltblown nonwoven fabric, and spunbond / meltblown / spunbond are laminated. A composite nonwoven fabric or a composite material thereof can be used. Even if it uses the same material as the packaging sheet 2, or a different material, the base material of the high friction material layer 3 can be used without a restriction | limiting in particular.

高摩擦材としては、例えば、熱可塑性樹脂、熱可塑性エラストマー、合成ゴム、天然ゴム等を含むものが使用できる。また、アルミナ、ゼオライト、バーミキュラライト等の無機微粒子、あるいは、熱可塑性樹脂、熱可塑性エラストマー等の合成樹脂、活性炭、もみ殻等の有機微粒子をバインダーに混合して使用することができる。 As the high friction material, for example, a material containing a thermoplastic resin, a thermoplastic elastomer, a synthetic rubber, a natural rubber or the like can be used. Further, inorganic fine particles such as alumina, zeolite and vermiculite, synthetic resins such as thermoplastic resins and thermoplastic elastomers, and organic fine particles such as activated carbon and rice husks can be mixed with a binder and used.

バインダーとしては、特に制限はないが、例えば、前記微粒子等を基材に固着できる合成樹脂をあげることができる。微粒子を包装シート２の基材に直接塗工するバインダーと、高摩擦材３の形成において、前記微粒子を基材に固着させるバインダーは、同じバインダーを用いても、異なるバインダーであっても、特に制限なく用いることができる。固着性 の点から、ポリアクリル酸エステル、酢酸ビニル−エチレン共重合体、酢酸ビニル−アクリル共重合体、ポリメチルメタクリレート、ポリスチレン、スチレンーアクリル系共重合体、ポリエステル樹脂、エポキシ樹脂、ブタジエン−スチレン共重合体等が好ましい。 Although there is no restriction | limiting in particular as a binder, For example, the synthetic resin which can adhere the said microparticles | fine-particles etc. to a base material can be mention | raise | lifted. The binder for directly applying the fine particles to the base material of the packaging sheet 2 and the binder for fixing the fine particles to the base material in the formation of the high friction material 3 may be the same binder or different binders. Can be used without limitation. From the standpoint of adhesiveness, polyacrylic acid ester, vinyl acetate-ethylene copolymer, vinyl acetate-acrylic copolymer, polymethyl methacrylate, polystyrene, styrene-acrylic copolymer, polyester resin, epoxy resin, butadiene-styrene A copolymer or the like is preferred.

塗工方法としては、特に制限はないが、例えば、ブレードコート、ロールコート、バーコート等の塗工方法をあげることができる。 The coating method is not particularly limited, and examples thereof include blade coating, roll coating, bar coating, and the like.

高摩擦材層３は、視認性を高めるために、高摩擦材層３の基材、あるいは、バインダーに対して、着色したものを用いることができる。着色方法は、基材やバインダーに、あらかじめ顔料、色素、染料等を含有させる等があげられる。また、バインダーに含む場合は、剥離しない程度の割合で含有することが好ましい。   As the high friction material layer 3, in order to improve visibility, a colored material can be used for the base material of the high friction material layer 3 or the binder. Examples of the coloring method include adding a pigment, a pigment, a dye, or the like to a base material or a binder in advance. Moreover, when it contains in a binder, it is preferable to contain in the ratio of the grade which does not peel.

また、包装シート２と包装シート２との間の静摩擦係数と、包装シート２と高摩擦材層３との間の静摩擦係数との差は、０．４以上であることが好ましい。静摩擦係数の差が０．４未満であると、使用者は、包装シート２の基材と高摩擦材層３の区別が付きにくくなってしまい、効率よく開封口２４を探すことが難しくなる。さらに、開封口２４の見つけやすさの向上の点から、好ましいのは０．５以上、最も好ましいのは０．６以上である。ここでの静摩擦係数とは、ＪＩＳ Ｐ ８１４７に記載された傾斜法に準拠して測定したものである。 Moreover, it is preferable that the difference of the static friction coefficient between the packaging sheet 2 and the packaging sheet 2 and the static friction coefficient between the packaging sheet 2 and the high friction material layer 3 is 0.4 or more. If the difference in the coefficient of static friction is less than 0.4, it becomes difficult for the user to distinguish between the base material of the packaging sheet 2 and the high friction material layer 3, and it becomes difficult to efficiently search for the opening 24. Furthermore, from the viewpoint of improving the ease of finding the opening 24, 0.5 or more is preferable, and 0.6 or more is most preferable. Here, the coefficient of static friction is measured in accordance with the gradient method described in JIS P 8147.

高摩擦材層３の長手方向及び幅方向の長さについて、特に制限はないが、長手方向の長さを１０ｍｍ以上とすることが好ましい。また、高摩擦材層３の幅方向の長さは、図１に示すように、包装シート２の幅と略同じとなるよう形成したり、図５に示すように、包装シート２の幅の一部分に形成したりすることができる。開封口２４の認識性の向上の点から、包装シート２の幅と略同じとなるよう形成することが好ましい。 Although there is no restriction | limiting in particular about the length of the longitudinal direction of the high friction material layer 3, and the width direction, It is preferable that the length of a longitudinal direction shall be 10 mm or more. Further, the length in the width direction of the high friction material layer 3 is formed so as to be substantially the same as the width of the packaging sheet 2 as shown in FIG. 1, or the width of the packaging sheet 2 as shown in FIG. Or can be formed in part. From the viewpoint of improving the recognizability of the opening 24, it is preferable to form it so as to be substantially the same as the width of the packaging sheet 2.

高摩擦材層３の厚さについて、特に制限はないが、０．１〜１．０ｍｍとすることが好ましい。０．１ｍｍ未満であると、包装体２から高摩擦材層３が剥離する恐れが生じる。１．０ｍｍより厚いと、剛性が高くなり、これも剥離しやすくなる。 Although there is no restriction | limiting in particular about the thickness of the high friction material layer 3, It is preferable to set it as 0.1-1.0 mm. If it is less than 0.1 mm, the high friction material layer 3 may be peeled off from the package 2. If it is thicker than 1.0 mm, the rigidity becomes high, and this also becomes easy to peel off.

以下の実施例により本発明をさらに具体的に説明する。なお、本発明はその要旨を超えない限り、以下の実施例の記載に限定されるものではない。 The following examples further illustrate the present invention. In addition, this invention is not limited to description of a following example, unless the summary is exceeded.

When the evaluation of (a) is 14 to 20 people, “◯”, when the evaluation of (a) is 8 to 13 people, “△”, and when the evaluation of (a) is 0 to 7 people, “X” Displayed.

［実施例２］、［比較例１］、［比較例２］
実施例２及び比較例１または２においては、表１に示す組成で、包装シート及び高摩擦材を調製し、実施例１と同様にして包装シートを製造した後、吸収性物品として軽失禁ライナーを包装し、静摩擦係数の測定及び官能評価を行った。その結果を表１に示す。 [Example 2], [Comparative Example 1], [Comparative Example 2]
In Example 2 and Comparative Example 1 or 2, after preparing a packaging sheet and a high friction material with the composition shown in Table 1 and producing the packaging sheet in the same manner as in Example 1, a light incontinence liner as an absorbent article Was packaged, and the coefficient of static friction was measured and sensory evaluation was performed. The results are shown in Table 1.

Figure 0006049188

高摩擦材層を形成していない比較例１の吸収性物品の包装体は、（Ａ）包装シートと前記包装シートとの間の静摩擦係数と、（Ｂ）包装シートと高摩擦材層との間の静摩擦係数の差がないため、開封口の位置を判断する材料が、開封口である前端縁部と後端縁部の隙間を手探りで探し当てることであるため、開封作業の難易度は高くなったと考えられる。また、（Ａ）包装シートどうしの静摩擦係数と、（Ｂ）包装シートと高摩擦材層の静摩擦係数の差が０．４未満の比較例２（０．１４）では、開封口の位置を判断するための感触の差が十分ではないことが分かった。それと比較して、（Ａ）と（Ｂ）の差が０．４以上の実施例１（０．４３）及び実施例２（０．７）では、開封口の先端部に設置した高摩擦材層と、包装シートとの感触の差が十分だったため、開封口を見つけやすく、包装体の開封が容易となったと考えられる。この結果から、包装シートと高摩擦材層との静摩擦係数差の閾値は、０．４であることが分かった。   The package of the absorbent article of Comparative Example 1 in which a high friction material layer is not formed includes (A) a coefficient of static friction between the packaging sheet and the packaging sheet, and (B) a packaging sheet and a high friction material layer. Since there is no difference in the coefficient of static friction between the two, the material used to determine the position of the opening is to find the gap between the front edge and the rear edge, which is the opening, by hand, so the difficulty of opening is high. It is thought that it became. Further, in Comparative Example 2 (0.14) in which the difference between the static friction coefficient between (A) the packaging sheets and (B) the static friction coefficient between the packaging sheet and the high friction material layer is less than 0.4, the position of the opening is determined. It was found that the difference in feel to do was not enough. In contrast, in Example 1 (0.43) and Example 2 (0.7) in which the difference between (A) and (B) is 0.4 or more, the high friction material installed at the tip of the opening Since the difference in touch between the layer and the packaging sheet was sufficient, it was considered that the opening was easy to find and the package was easily opened. From this result, it was found that the threshold value of the static friction coefficient difference between the packaging sheet and the high friction material layer was 0.4.
