Description

本発明は、前胴回り域、後胴回り域及び股下域を有する展開型吸収性物品、吸収性物品の包装体、及び吸収性物品の包装体の製造方法に関する。 TECHNICAL FIELD The present invention relates to an unfoldable absorbent article having a front waist region, a rear waist region and a crotch region, an absorbent article package, and a method for manufacturing an absorbent article package.

特許文献１には、前胴回り域、後胴回り域及び股下域を有する展開型吸収性物品が開示されている。特許文献１の展開型吸収性物品は、複数回折り畳まれた状態で袋状の包装シートに収容されている。具体的には、展開型吸収性物品が折り目によって折り畳まれてない展開状態から、吸収コアよりも幅方向の外側に位置し、かつ前後方向に沿った前後折り目を基点に折り畳まれ、次いで、前後折り目を基点に折り畳まれた状態で、吸収性物品の前後方向のほぼ中央に位置し、かつ幅方向に沿った幅折り目を基点に折り畳まれる。このように、前後折り目及び幅折り目を基点に折り畳まれた状態で、包装シートに収容されている（特許文献１の図１参照）。 Patent Literature 1 discloses an unfoldable absorbent article having a front waist region, a back waist region and a crotch region. The unfoldable absorbent article of Patent Literature 1 is accommodated in a bag-shaped packaging sheet in a state of being folded multiple times. Specifically, from the unfolded state in which the unfolded absorbent article is not folded at the creases, the unfolded absorbent article is folded around the front and back folds located outside the absorbent core in the width direction and along the front and back direction, and then folded back and forth. In a state where the absorbent article is folded around the crease, the absorbent article is folded around the width crease along the width direction, which is positioned substantially in the center in the front-rear direction of the absorbent article. In this way, it is stored in the packaging sheet in a state of being folded around the front and rear folds and the width fold (see FIG. 1 of Patent Document 1).

特開２００５－４７５２３号公報JP-A-2005-47523

このように構成された展開型吸収性物品には、使用前に折り畳まれた折り目による折り癖が付いている。幅折り目は、吸収コアの幅方向の全域に亘って肌面側同士が向き合うように折り畳む折り目である。そのため、当該幅折り目によって吸収コアの幅方向の全域に亘って、着用者の股間から離れるように変形し、横漏れが発生するおそれがあった。特に、前胴回り域、後胴回り域及び股下域を有する吸収性物品は、それ自体が身体を覆う部位を備えており、ナプキン等のように着用物品を介して身体に押し当てられるものではなく、吸収性物品自体の折り癖が着用状態の形状に影響しやすい。 The unfoldable absorbent article constructed in this way has creases due to the creases that have been folded before use. The width crease is a crease that is folded so that the skin surfaces face each other across the entire width direction of the absorbent core. Therefore, there is a risk that the width crease will cause the absorbent core to be deformed away from the crotch of the wearer over the entire area in the width direction, causing side leakage. In particular, an absorbent article having a front waist region, a back waist region, and a crotch region has a portion that covers the body itself, and is not pressed against the body through a worn article like a napkin. The crease of the absorbent article itself tends to affect the shape of the absorbent article when worn.

また、特許文献１の展開型吸収性物品において、折り畳まれた状態の前後方向の長さは、展開状態の約半分であり、折り畳まれた状態の幅方向の長さは、吸収コアの幅方向の長さ以上である。そのため、折り畳まれた状態における前後方向及び幅方向の長さが長く、持ち運び時にコンパクトに吸収性物品を収納し難かった。 In addition, in the unfoldable absorbent article of Patent Document 1, the length in the front-rear direction in the folded state is about half that in the unfolded state, and the length in the width direction in the folded state is the width direction of the absorbent core. is greater than or equal to the length of Therefore, the length in the front-rear direction and the width direction in the folded state is long, and it is difficult to store the absorbent article compactly when carrying.

よって、前胴回り域、後胴回り域及び股下域を有する吸収性物品において、使用前の折り癖に起因する横漏れの発生を抑制でき、使用前にコンパクトに収容できる展開型吸収性物品を提供することを目的とする。 Therefore, in an absorbent article having a front waist region, a rear waist region, and a crotch region, side leakage due to creases before use can be suppressed, and a spreadable absorbent article that can be compactly accommodated before use is provided. for the purpose.

一態様に係る展開型吸収性物品は、互いに直交する前後方向及び幅方向と、着用者の前胴回りを覆う前胴回り域と、前記着用者の後胴回りを覆う後胴回り域と、前記前胴回り域と前記後胴回り域との間に配置された股下域と、少なくとも前記股下域に配置された吸収コアと、を有する。前記吸収性物品は、前記幅方向に沿った幅折り目と、前記前後方向に沿った前後折り目と、を基点に折り畳まれている。前記前後折り目は、前記股下域の吸収コアを、前記吸収コアの肌面側同士が向き合うように折り畳むコア前後折り目を有する。 An expandable absorbent article according to one aspect includes a front-back direction and a width direction perpendicular to each other, a front waist region covering the front waist of a wearer, a back waist region covering the back waist of the wearer, and the front waist region. and the back waist region, and an absorbent core disposed at least in the crotch region. The absorbent article is folded on the basis of the width crease along the width direction and the front-rear crease along the front-rear direction. The front-rear fold has a core front-rear fold that folds the absorbent core in the crotch region so that the skin surfaces of the absorbent core face each other.

一態様に係る展開型吸収性物品の包装体は、前記吸収性物品と、前記吸収性物品を個別に包装する包装シートと、を有する。前記吸収性物品と前記包装シートにそれぞれ当接し、前記吸収性物品と前記包装シートを仮接合する仮接合部が設けられている。前記仮接合部の前記包装シートに対する接合強度は、前記仮接合部の前記吸収性物品に対する接合強度よりも高い。 A package for a spreadable absorbent article according to one aspect includes the absorbent article and a packaging sheet for individually wrapping the absorbent article. Temporary joining portions are provided that contact the absorbent article and the packaging sheet, respectively, and temporarily join the absorbent article and the packaging sheet. The bonding strength of the temporary bonding portion to the packaging sheet is higher than the bonding strength of the temporary bonding portion to the absorbent article.

一態様に係る展開型吸収性物品の製造方法は、互いに直交する前後方向及び幅方向と、着用者の前胴回りを覆う前胴回り域と、前記着用者の後胴回りを覆う後胴回り域と、前記前胴回り域と前記後胴回り域との間に配置された股下域と、少なくとも前記股下域に配置された吸収コアと、を有する展開型吸収性物品と、前記吸収性物品を個別に包装する包装シートと、を有する吸収性物品の包装体の製造方法である。前記股下域の吸収コアを、肌面側同士が向き合うように前後折り目を基点に折り畳む第１工程と、前記第１折り畳み工程によって折り畳まれた吸収性物品を、前記包装シート上に載置する第２工程と、前記第２工程の後に、前記コア前後折り目に沿って前記包装シートを折り畳む第３工程と、前記第３工程の後に、前記包装シート及び前記吸収性物品を、前記幅方向に沿って延びる幅折り目を基点に折り畳む第４工程と、を有する。 A method for manufacturing an expandable absorbent article according to one aspect comprises a front-rear direction and a width direction perpendicular to each other, a front waist region covering the front waist of a wearer, a back waist region covering the back waist of the wearer, and An unfoldable absorbent article having a crotch region arranged between a front waist region and a back waist region, and an absorbent core arranged at least in the crotch region; and a package for individually wrapping the absorbent article.

（１）実施形態の概要
本明細書及び添付図面の記載により、少なくとも以下の事項が明らかとなる。
一態様に係る展開型吸収性物品は、互いに直交する前後方向及び幅方向と、着用者の前胴回りを覆う前胴回り域と、前記着用者の後胴回りを覆う後胴回り域と、前記前胴回り域と前記後胴回り域との間に配置された股下域と、少なくとも前記股下域に配置された吸収コアと、を有する。前記吸収性物品は、前記幅方向に沿った幅折り目と、前記前後方向に沿った前後折り目と、を基点に折り畳まれている。前記前後折り目は、前記股下域の吸収コアを、前記吸収コアの肌面側同士が向き合うように折り畳むコア前後折り目を有する。吸収コアには、少なくともコア前後折り目による折り癖が形成される。コア前後折り目が、吸収性物品の肌面側同士が向き合うように折り畳む折り目であるため、コア前後折り目よりも幅方向外側の領域は、折り癖によって着用者側に立ち上がる。そのため、股下域の吸収コアの幅方向の側部が折り癖によって着用者側に立ち上がるように変形し、横漏れを抑制できる。また、コア前後折り目によって吸収コアを折り畳むため、折り畳んだ状態の吸収性物品の幅方向の長さを短くし易く、使用前にコンパクトに吸収性物品を収容できる。 (1) Overview of Embodiments At least the following matters will become clear from the description of this specification and the accompanying drawings.
An expandable absorbent article according to one aspect includes a front-back direction and a width direction perpendicular to each other, a front waist region covering the front waist of a wearer, a back waist region covering the back waist of the wearer, and the front waist region. and the back waist region, and an absorbent core disposed at least in the crotch region. The absorbent article is folded on the basis of the width crease along the width direction and the front-rear crease along the front-rear direction. The front-rear fold has a core front-rear fold that folds the absorbent core in the crotch region so that the skin surfaces of the absorbent core face each other. The absorbent core is formed with at least creases due to core front-rear folds. Since the core front-rear folds are folds for folding the absorbent article so that the skin sides of the absorbent article face each other, the region outside the core front-rear folds in the width direction rises toward the wearer due to the crease. Therefore, the widthwise side portions of the absorbent core in the crotch region are deformed so as to stand up toward the wearer due to the crease, thereby suppressing side leakage. In addition, since the absorbent core is folded along the core front-rear folds, the length of the absorbent article in the folded state in the width direction can be easily shortened, and the absorbent article can be stored compactly before use.

好ましい一態様によれば、前記コア前後折り目は、前記吸収コアの前記幅方向の中心を挟んで一対で設けられてよい。おむつ等の吸収性物品は、不定期で***される尿等の***物を保持するように構成されており、ナプキンのように断続的に***される経血を保持する構成と異なり、身体から密着させずに股下域を配置することが好ましい。一対のコア前後折り目間の領域に対してコア前後折り目よりも外側の領域が立ち上がり、幅方向に沿った断面においてカップ形状となる。そのため、体液を保持する空間をより大きく確保できる。コア前後折り目の近傍が折り癖によって身体から離れ、体液を保持する空間を確保できる。 According to a preferred aspect, the core front-rear fold line may be provided as a pair across the center of the absorbent core in the width direction. Absorbent articles such as diapers are configured to retain excrement such as urine that is excreted at irregular intervals. It is preferable to arrange the crotch region without making it close. A region outside the core front-rear fold rises with respect to a region between the pair of core front-rear folds, and has a cup shape in a cross section along the width direction. Therefore, a larger space for holding body fluid can be secured. The vicinity of the core front and rear folds is separated from the body due to the crease, and a space for holding body fluids can be secured.

好ましい一態様によれば、前記前後折り目は、展開状態において前記吸収コアよりも前記幅方向の外側に位置し、肌面側同士が向き合うように前記吸収性物品を折り畳む物品前後折り目を有し、前記コア前後折り目は、前記物品前後折り目を基点に折り畳まれた第１折り状態において、前記吸収コアを折り畳んでよい。本態様によれば、物品前後折り目及びコア前後折り目によって幅方向に吸収性物品を折り畳むことができ、使用前の吸収性物品の幅方向の長さをより短くできる。また、物品前後折り目による折り癖は、吸収性物品の肌面側同士が向き合う折り癖となる。幅方向において物品前後折り目を挟んだ両側を、身体側に立ち上げることができ、着用時のフィット性を高めることができる。 According to a preferred aspect, the front and rear folds are located outside the absorbent core in the width direction in the unfolded state, and have an article front and rear fold for folding the absorbent article so that the skin surfaces face each other, The core front-rear fold line may fold the absorbent core in a first folded state in which the article is folded around the article front-rear fold line. According to this aspect, the absorbent article can be folded in the width direction by the article front-rear fold line and the core front-rear fold line, and the length of the absorbent article in the width direction before use can be further shortened. In addition, the crease due to the front and rear folds of the article is a crease in which the skin sides of the absorbent article face each other. Both sides sandwiching the front and rear folds of the article in the width direction can be set up on the body side, and the fit when worn can be improved.

好ましい一態様によれば、前記幅折り目は、前記コア前後折り目を基点に折り畳まれた第２折り状態において、前記吸収性物品を折り畳んでよい。本態様によれば、幅折り目を基点に折り畳むことにより、吸収性物品の幅方向の長さを短くした状態で、更に吸収性物品の前後方向の長さを短くできる。使用前にコンパクトに吸収性物品を収容できる。また、コア前後折り目によって折り畳んだ後に幅折り目を基点に折り畳むため、コア前後折り目の折り癖がより強くつきやすく、また折られた状態を維持し易くなる。よって、折り癖によって横漏れを抑制する効果をより得やすい。 According to a preferred aspect, the width crease may fold the absorbent article in a second folded state in which the absorbent article is folded with the core front-rear crease as a base point. According to this aspect, the length of the absorbent article in the front-rear direction can be further shortened while the length of the absorbent article in the width direction is shortened by folding the absorbent article at the width crease. Absorbent articles can be stored compactly before use. In addition, since the core is folded along the front-rear crease and then folded with the width crease as the base point, the crease at the core's back-rear crease tends to be stronger and the folded state can be easily maintained. Therefore, it is easier to obtain the effect of suppressing side leakage due to the crease.

好ましい一態様によれば、前記幅折り目は、前記前後方向に間隔を空けて一対で設けられてよい。本態様によれば、吸収性物品の前後方向の長さをより短くでき、使用前にコンパクトに吸収性物品を収容できる。 According to a preferred aspect, the width folds may be provided as a pair spaced apart in the front-rear direction. According to this aspect, the length of the absorbent article in the front-rear direction can be shortened, and the absorbent article can be stored compactly before use.

一態様に係る展開型吸収性物品の包装体は、前記吸収性物品と、前記吸収性物品を個別に包装する包装シートと、を有する。前記吸収性物品と前記包装シートにそれぞれ当接し、前記吸収性物品と前記包装シートを仮接合する仮接合部が設けられている。前記仮接合部の前記包装シートに対する接合強度は、前記仮接合部の前記吸収性物品に対する接合強度よりも高い。仮接合部によって包装シートと吸収性物品の相対位置を固定でき、安定して折り畳むことができる。仮接合部は、包装シートに対する接合強度が高く、かつ吸収性物品に対する接合強度が低い。そのため、使用時に包装シートから吸収性物品を剥がした際に、包装シート側に仮接合部が残りやすい。使用時に吸収性物品に仮接合部が付着していないため、使用時に吸収性物品の非肌面側に仮接合部が配置されることに起因する違和感を抑制できる。 A package for a spreadable absorbent article according to one aspect includes the absorbent article and a packaging sheet for individually wrapping the absorbent article. Temporary joining portions are provided that contact the absorbent article and the packaging sheet, respectively, and temporarily join the absorbent article and the packaging sheet. The bonding strength of the temporary bonding portion to the packaging sheet is higher than the bonding strength of the temporary bonding portion to the absorbent article. The temporary joint portion can fix the relative position of the packaging sheet and the absorbent article, and the absorbent article can be stably folded. The temporary joint has high joint strength to the packaging sheet and low joint strength to the absorbent article. Therefore, when the absorbent article is peeled off from the packaging sheet at the time of use, the temporary joints tend to remain on the packaging sheet side. Since the temporary joints are not attached to the absorbent article during use, it is possible to suppress discomfort due to the provisional joints being arranged on the non-skin surface side of the absorbent article during use.

好ましい一態様によれば、前記仮接合部は、前記吸収コアと重なる領域に配置されてよい。吸収コアは、吸収性物品の中でも剛性が高い部材である。比較的剛性が高い吸収コアと重なる領域を、仮接合部によって包装シートに固定することにより、吸収性物品と包装シートの位置を安定させることができる。 According to a preferred aspect, the temporary joint may be arranged in a region overlapping the absorbent core. The absorbent core is a highly rigid member among absorbent articles. The position of the absorbent article and the packaging sheet can be stabilized by fixing the area overlapping the absorbent core, which has relatively high rigidity, to the packaging sheet by means of the temporary joint.

好ましい一態様によれば、前記吸収性物品は、前記吸収コアよりも肌側に位置する起立性の防漏ギャザーを有しており、前記防漏ギャザーは、前記吸収コアよりも肌面側に位置する表面シートに固定された固定部と、前記表面シートに対して起立可能な起立部と、を有し、前記幅折り目は、前記起立部の前後方向の中心を挟んで、前記前後方向に間隔を空けて一対で設けられており、前記仮接合部の少なくとも一部は、前記幅折り目よりも前記前後方向の外側にそれぞれ配置されてよい。吸収性物品において仮接合部と重なる領域は、使用時に展開した状態において包装シート側に引っ張られる力がかかる。防漏ギャザーの起立部の前後方向の中心よりも前後方向の外側に、仮接合部が配置されているため、仮接合部を介して包装シート側に引っ張られる。このとき、仮接合部が幅折り目よりも外側に配置されているため、幅折り目を基点として幅折り目よりも前後方向の外側の領域がより展開し易い。よって、幅折り目間に位置する起立部が立ち上がり易くなる。防漏ギャザーの起立性が向上することにより、横漏れをより抑制できる。 According to a preferred aspect, the absorbent article has upright leak-proof gathers positioned closer to the skin than the absorbent core, and the leak-proof gathers are positioned closer to the skin than the absorbent core. It has a fixing portion fixed to the positioned surface sheet and an upright portion that can stand up with respect to the topsheet, and the width crease extends in the front-rear direction across the center of the upright portion in the front-rear direction. A pair of temporary joints may be provided with a space therebetween, and at least a part of the temporary joint may be arranged outside the width crease in the front-rear direction. A region of the absorbent article that overlaps the temporary joint is subjected to a pulling force toward the packaging sheet in the unfolded state during use. Since the temporary joint portion is arranged outside in the front-rear direction from the center in the front-rear direction of the upright portion of the leak-proof gather, it is pulled toward the packaging sheet through the temporary joint portion. At this time, since the temporary joint portion is arranged outside the width crease, the region outside the width crease in the front-rear direction is more likely to expand with the width crease as a base point. Therefore, the standing portion located between the width creases can be easily raised. Side leakage can be further suppressed by improving the uprightness of the leakage-preventing gathers.

好ましい一態様によれば、前記吸収性物品は、前記吸収コアよりも肌側に位置する起立性の防漏ギャザーを有しており、前記防漏ギャザーは、前記吸収コアよりも肌面側に位置する表面シートに固定された固定部と、前記表面シートに対して起立可能な起立部と、を有し、前記仮接合部の少なくとも一部は、展開状態において、前記起立部よりも前記前後方向の外側に位置してよい。吸収性物品において仮接合部と重なる領域は、展開状態において包装シート側に引っ張られる力がかかる。防漏ギャザーの起立部よりも前後方向の外側の領域が、仮接合部を介して包装シート側に引っ張られることにより、起立部が立ち上がり易くなる。防漏ギャザーの起立性が向上することにより、横漏れをより抑制できる。 According to a preferred aspect, the absorbent article has upright leak-proof gathers positioned closer to the skin than the absorbent core, and the leak-proof gathers are positioned closer to the skin than the absorbent core. It has a fixing portion fixed to a positioned surface sheet, and an upright portion that can stand up with respect to the topsheet, and at least a part of the temporary joint portion is positioned in the unfolded state from the front and rear of the upright portion. may be located outside the direction. In the unfolded state, a pulling force is applied to the region of the absorbent article that overlaps the temporary joint portion toward the packaging sheet. A region outside the upright portion of the leak-proof gather in the front-rear direction is pulled toward the packaging sheet through the temporary joint, thereby making the upright portion easier to stand up. Side leakage can be further suppressed by improving the uprightness of the leakage-preventing gathers.

次いで、図３に基づいて、吸収性物品の包装体１の製造方法における折り畳み工程について説明する。なお、包装体の製造方法は、以下において説明する折り畳み工程を含んでいればよく、折り畳み工程以外の工程については、周知の工程を用いることができる。また、以下の折り畳み態様の説明においては、吸収性物品１０と包装シート１００の両方を折り畳む包装体の折り畳み態様を説明するが、変形例において、吸収性物品１０のみを折り畳んでもよい。吸収性物品１０及び包装シート１００の展開状態（図３（Ａ）に示す状態）において、吸収性物品１０を、第１前後折り目ＦＬ１を基点に折り畳む。図３（Ｂ）は、第１前後折り目ＦＬ１を基点に折り畳んだ第１折り状態を示している。次いで、第１折り状態において、吸収性物品１０を、第２前後折り目ＦＬ２を基点に折り畳む第１工程を有する。第１折り状態において、第２前後折り目ＦＬ２は、第１前後折り目ＦＬ１よりも幅方向Ｗの内側に位置する。なお、第１工程は、第１折り状態において第２前後折り目ＦＬ２を基点に吸収性物品１０を折り畳む工程であってもよいし、展開状態において第２前後折り目ＦＬ２を基点に吸収性物品１０を折り畳む工程であってもよい。第１工程によって折り畳まれた吸収性物品１０を、包装シート１００上に載置する第２工程を有する。図３（Ｃ）は、第２前後折り目ＦＬ２を基点に折り畳んだ第２折り状態であって、第２工程の後の状態を示している。第２工程の後に、包装シート１００を、第３前後折り目ＦＬ３に沿って包装シート１００を折り畳む第３工程を有する。第３工程は、吸収性物品１０の第２前後折り目ＦＬ２に沿った第３前後折り目ＦＬ３を基点に包装シート１００を折り畳む。第３前後折り目ＦＬ３の幅方向Ｗの位置は、第２前後折り目ＦＬ２と略一致している。換言すると、第３前後折り目ＦＬ３は、第２前後折り目ＦＬ２に沿って形成されてよい。図３（Ｄ）は、一対の第３前後折り目ＦＬ３のうち一方の第３前後折り目ＦＬ３を基点に折り畳まれた状態であり、図３（Ｅ）は、一対の第３前後折り目ＦＬ３の両方を基点に折り畳んだ第３折り状態を示している。第３工程は、折り畳んだ包装シート１００同士が重なるように折り畳み、包装接合部１０１を介して重なった包装シート１００同士を接合してもよい。包装接合部１０１を介して包装シート１００同士を接合することにより、折り畳んだ包装シートが展開せずに折り畳んだ状態を維持でき、吸収性物品１０をよりコンパクトに収容できる。 Next, the folding step in the manufacturing method of the absorbent article package 1 will be described with reference to FIG. In addition, the manufacturing method of a package should just include the folding process demonstrated below, and a well-known process can be used about processes other than a folding process. In addition, in the description of the folding mode below, the folding mode of the package in which both the absorbent article 10 and the packaging sheet 100 are folded will be described, but in a modified example, only the absorbent article 10 may be folded. In the unfolded state of the absorbent article 10 and the packaging sheet 100 (the state shown in FIG. 3A), the absorbent article 10 is folded around the first front-back fold line FL1. FIG. 3(B) shows the first folded state in which the first front-rear folding line FL1 is the base point. Next, in the first folded state, there is a first step of folding the absorbent article 10 around the second front-back fold line FL2. In the first folded state, the second front-rear fold line FL2 is located inside in the width direction W from the first front-rear fold line FL1. The first step may be a step of folding the absorbent article 10 in the first folded state with the second front-rear fold line FL2 as a base point, or folding the absorbent article 10 in the unfolded state with the second front-rear fold line FL2 as a base point. It may be a folding step. It has a second step of placing the absorbent article 10 folded in the first step on the packaging sheet 100 . FIG. 3(C) shows a second folding state in which the sheet is folded around the second front-rear folding line FL2, and shows a state after the second step. After the second step, there is a third step of folding the packaging sheet 100 along the third front-back fold line FL3 . In the third step, the packaging sheet 100 is folded around the third front-rear fold line FL3 along the second front-rear fold line FL2 of the absorbent article 10 . The position of the third front-rear fold line FL3 in the width direction W substantially coincides with the second front-rear fold line FL2. In other words, the third front-rear fold line FL3 may be formed along the second front-rear fold line FL2. FIG. 3(D) shows a state in which one of the pair of third front-rear folds FL3 is folded with one of the third front-rear folds FL3 as a base point, and FIG. The third folding state folded to the base point is shown. In the third step, the folded packaging sheets 100 may be folded to overlap each other, and the overlapped packaging sheets 100 may be joined via the packaging joint portion 101 . By bonding the packaging sheets 100 to each other via the packaging bonding portion 101, the folded packaging sheet can be maintained in a folded state without unfolding, and the absorbent article 10 can be accommodated more compactly.

次いで、第３工程の後に、包装シート１００及び吸収性物品１０を、幅方向Ｗに沿って延びる幅折り目ＦＷを基点に折り畳む第４工程を有する。第４工程は、第１幅折り目ＦＷ１を基点に、吸収性物品１０及び包装シート１００を折り畳む。図３（Ｆ）は、第１幅折り目ＦＷ１を基点に折り畳んだ第４折り状態を示している。第４工程は、第４折り状態において、第２幅折り目ＦＷ２を基点に、吸収性物品１０及び包装シート１００を折り畳む工程を有してよい。図３（Ｇ）は、第２幅折り目ＦＷ２を基点に折り畳んだ第５折り状態を示している。このようにして、吸収性物品１０を包装シート１００によって個別に包装し、包装体１をコンパクトに形成できる。また、使用時の吸収性物品１０には、前後折り目ＦＬと幅折り目ＦＷによる折り癖が形成される。 Then, after the third step, there is a fourth step of folding the packaging sheet 100 and the absorbent article 10 with the width crease FW extending along the width direction W as a base point. In the fourth step, the absorbent article 10 and the packaging sheet 100 are folded around the first width crease FW1. FIG. 3(F) shows a fourth folding state in which the first width crease FW1 is the base point. The fourth step may include folding the absorbent article 10 and the packaging sheet 100 in the fourth folded state with the second width crease FW2 as a base point. FIG. 3(G) shows the fifth folded state in which the second width crease FW2 is the base point. In this way, the absorbent articles 10 can be individually wrapped with the wrapping sheet 100, and the package 1 can be compactly formed. In addition, the absorbent article 10 in use has creases formed by the front and rear fold lines FL and the width fold lines FW.

複数の前後折り目のうち少なくとも一部の前後折り目ＦＬは、吸収コア３１に重なってよい。本実施の形態では、第２前後折り目ＦＬ２及び第３前後折り目ＦＬ３は、吸収コア３１に重なっており、第１前後折り目ＦＬ１は、吸収コア３１に重なっていない。前後折り目ＦＬによって吸収コア３１を折り畳むことにより、前後折り目ＦＬが吸収コア３１に重ならない構成と比較して、折り畳んだ状態の吸収性物品１０の幅方向Ｗの長さを短くしやすい。よって、製品の幅方向Ｗの長さが比較的長いおむつであっても、使用前にコンパクトに吸収性物品１０を収容できる。 At least some of the front and rear fold lines FL may overlap the absorbent core 31 . In the present embodiment, the second front-rear fold FL2 and the third front-rear fold FL3 overlap the absorbent core 31, and the first front-rear fold FL1 does not overlap the absorbent core 31. As shown in FIG. By folding the absorbent core 31 along the front and back fold lines FL, the length in the width direction W of the absorbent article 10 in the folded state can be easily shortened compared to a configuration in which the front and rear fold lines FL do not overlap the absorbent core 31 . Therefore, even if the diaper has a relatively long length in the width direction W of the product, the absorbent article 10 can be stored compactly before use.

第２前後折り目ＦＬ２は、股下域Ｓ３の吸収コア３１を、吸収コア３１の肌面側同士が向き合うように折り畳む。換言すると、第２前後折り目ＦＬ２は、吸収コア３１に重なっており、吸収コア３１を谷折りする折り目である。第２前後折り目ＦＬ２が、吸収性物品１０の肌面側同士が向き合うように折り畳む折り目であるため、第２前後折り目ＦＬ２よりも幅方向Ｗ外側の領域は、使用時に折り癖によって着用者側に立ち上がる。そのため、股下域Ｓ３の吸収コア３１の幅方向Ｗの側部が折り癖によって着用者側に立ち上がるように変形する。仮に幅折り目ＦＷの折り癖によって吸収コア３１が着用者の股間から離れるように変形した場合であっても、第２前後折り目ＦＬ２の折り癖によって着用者の股間の側方を覆うことができ、横漏れを抑制できる。なお、第１前後折り目ＦＬ１は、少なくとも股下域Ｓ３の吸収コア３１に重なっていてよく、本実施の形態のように吸収コア３１の前後方向Ｌの全域に亘って吸収コア３１に重なっていてもよい。 The second front-rear fold line FL2 folds the absorbent core 31 in the crotch region S3 so that the skin surface sides of the absorbent core 31 face each other. In other words, the second front-rear fold line FL2 is a fold line that overlaps the absorbent core 31 and folds the absorbent core 31 into a valley. Since the second front-rear fold line FL2 is a fold line for folding the absorbent article 10 so that the skin sides of the absorbent article 10 face each other, the region outside the second front-rear fold line FL2 in the width direction W may be bent toward the wearer due to the crease during use. stand up. Therefore, the sides of the absorbent core 31 in the width direction W of the crotch region S3 are deformed so as to stand up toward the wearer due to the crease. Even if the absorbent core 31 is deformed away from the wearer's crotch due to the crease of the width crease FW, the crease of the second front-back crease FL2 can cover the sides of the wearer's crotch. Side leakage can be suppressed. Note that the first front-rear fold line FL1 may overlap at least the absorbent core 31 in the crotch region S3, and may overlap the absorbent core 31 over the entire area in the front-rear direction L of the absorbent core 31 as in the present embodiment. good.

おむつ等の吸収性物品は、不定期で***される尿等の***物を保持するように構成されており、ナプキンのように断続的に***される経血を保持する構成と異なり、身体から密着させずに股下域を配置することが好ましい。第２前後折り目ＦＬ２は、吸収コア３１の幅方向Ｗの中心３１ＷＣに位置してよい。このような構成によれば、吸収コア３１の幅方向Ｗの中心３１ＷＣが着用者から離れ、第２前後折り目ＦＬ２を挟んだ両側が着用者側に立ち上がるように変形する。このとき、第２前後折り目ＦＬ２の近傍が身体から離れ、体液を保持する空間を確保できる。より好適には、吸収コア３１の幅方向Ｗの中心３１ＷＣを挟んで一対で設けられてよい。吸収コア３１の幅方向Ｗの中心３１ＷＣは、吸収性物品１０の幅方向Ｗの中心に一致してよい。このような構成によれば、一対の第２前後折り目ＦＬ２によって挟まれた領域に対して第２前後折り目ＦＬ２よりも外側の領域が立ち上がり、幅方向に沿った断面においてカップ形状となる。一対の第２前後折り目ＦＬ２によって挟まれた領域は、身体から密着せずに股下域に沿って配置され易く、カップ形状によって体液を保持する空間を確保できる。また、第２前後折り目ＦＬ２よりも外側の領域が立ち上がることで横漏れを抑制できる。 Absorbent articles such as diapers are configured to retain excrement such as urine that is excreted at irregular intervals. It is preferable to arrange the crotch region without making it close. The second front-rear fold line FL2 may be positioned at the center 31WC in the width direction W of the absorbent core 31 . According to such a configuration, the center 31WC in the width direction W of the absorbent core 31 is separated from the wearer, and both sides of the second front-back fold line FL2 are deformed so as to rise toward the wearer. At this time, the vicinity of the second front-rear fold line FL2 is separated from the body, and a space for retaining body fluid can be secured. More preferably, they may be provided as a pair across the center 31WC in the width direction W of the absorbent core 31 . The center 31WC in the width direction W of the absorbent core 31 may coincide with the center in the width direction W of the absorbent article 10 . According to such a configuration, the region outside the second front and rear fold line FL2 rises with respect to the region sandwiched between the pair of second front and rear fold lines FL2, and has a cup shape in cross section along the width direction. The area sandwiched by the pair of second front-rear fold lines FL2 can be easily arranged along the crotch area without coming into close contact with the body, and the cup shape can ensure a space for retaining bodily fluids. In addition, lateral leakage can be suppressed by raising the area outside the second front-back fold line FL2.

第１前後折り目ＦＬ１は、展開状態において吸収コアよりも幅方向の外側に位置し、吸収性物品の肌面側同士が向き合うように吸収性物品を折り畳む折り目であってよい。第２前後折り目ＦＬ２は、第１前後折り目ＦＬ１を基点に折り畳まれた第１折り状態において、吸収コア３１を折り畳んでよい。第１前後折り目ＦＬ１を基点に吸収性物品１０を折り畳んで、吸収性物品１０の幅方向の長さを短くした状態で、第２前後折り目ＦＬ２を基点に吸収性物品１０を折り畳んで、更に吸収性物品１０の幅方向の長さを短くできる。そのため、使用前の吸収性物品１０の幅方向Ｗの長さをより短くできる。また、第１前後折り目ＦＬ１による折り癖は、吸収性物品１０の肌面側同士が向き合う折り癖となる。幅方向Ｗにおいて第１前後折り目ＦＬ１を挟んだ両側を、身体側に立ち上げることができ、着用時のフィット性を高めることができる。 The first front-rear fold line FL1 may be a fold line that is located outside the absorbent core in the width direction in the unfolded state and folds the absorbent article so that the skin sides of the absorbent article face each other. The second front-rear fold line FL2 may fold the absorbent core 31 in the first folded state in which the absorbent core 31 is folded with the first front-rear fold line FL1 as the base point. The absorbent article 10 is folded around the first front-rear fold line FL1 to shorten the length of the absorbent article 10 in the width direction. The length in the width direction of the functional article 10 can be shortened. Therefore, the length in the width direction W of the absorbent article 10 before use can be made shorter. Further, the crease due to the first front-rear crease FL1 is such that the skin sides of the absorbent article 10 face each other. Both sides of the first front-rear fold line FL1 in the width direction W can be raised toward the wearer's body, thereby improving the fit when worn.

第１前後折り目ＦＬ１及び第２前後折り目ＦＬ２を基点に吸収性物品１０を折り畳んだ後に、第３前後折り目ＦＬ３を基点に包装シート１００を折り畳んでよい。このような構成によれば、一旦折り畳んだ吸収性物品１０を、再度折り畳むことができる。そのため、更にコンパクトに折り畳むことができる。特に、使い捨ておむつのように幅方向の長さが比較的長い吸収性物品において、好適に適用できる。 After folding the absorbent article 10 around the first front-back fold line FL1 and the second front-back fold line FL2, the packaging sheet 100 may be folded around the third front-back fold line FL3. According to such a configuration, the once folded absorbent article 10 can be folded again. Therefore, it can be folded more compactly. In particular, it can be suitably applied to absorbent articles having a relatively long length in the width direction, such as disposable diapers.

幅折り目ＦＷは、第２前後折り目ＦＬ２を基点に折り畳まれた第２折状態において、吸収性物品１０を折り畳んでよい。なお、第２折り状態は、上述のように、第１前後折り目ＦＬ１及び第２前後折り目ＦＬ２を基点に折り畳んだ状態であってもよいし、第１前後折り目ＦＬ１を有しない形態にあっては、第２前後折り目ＦＬ２のみを基点に折り畳んだ状態であってもよい。幅折り目を基点に折り畳むことにより、吸収性物品１０の幅方向Ｗの長さを短くした状態で、更に吸収性物品１０の前後方向Ｌの長さを短くできる。使用前にコンパクトに吸収性物品１０を収容できる。また、第２前後折り目ＦＬ２によって折り畳んだ後に幅折り目ＦＷを基点に折り畳むため、第２前後折り目ＦＬ２の折り癖がより強くつきやすく、また折られた状態を維持し易くなる。よって、折り癖によって横漏れを抑制する効果をより得やすい。 The width crease FW may fold the absorbent article 10 in the second folded state in which the absorbent article 10 is folded with the second front-rear crease FL2 as a base point. As described above, the second folded state may be a state in which the first front-rear fold line FL1 and the second front-rear fold line FL2 are used as base points, or a state in which the first front-rear fold line FL1 is not provided. , the state in which only the second front-back fold line FL2 is the base point. By folding the absorbent article 10 with the width crease as the base point, the length of the absorbent article 10 in the front-rear direction L can be further shortened while the length of the absorbent article 10 in the width direction W is shortened. The absorbent article 10 can be stored compactly before use. In addition, after being folded along the second front-rear fold line FL2, the product is folded with the width fold line FW as the base point, so that the second front-rear fold line FL2 tends to form a stronger crease, and the folded state can be easily maintained. Therefore, it is easier to obtain the effect of suppressing side leakage due to the crease.

幅折り目ＦＷは、前後方向Ｌに間隔を空けて一対で設けられてよい。換言すると、幅折り目ＦＷは、前後方向Ｌに離間した第１幅折り目ＦＷ１及び第２幅折り目ＦＷ２を有してよい。吸収性物品１０の前後方向Ｌの長さをより短くでき、使用前にコンパクトに吸収性物品１０を収容できる。 The width crease FW may be provided as a pair spaced apart in the front-rear direction L. In other words, the width fold FW may have a first width fold FW1 and a second width fold FW2 spaced apart in the front-rear direction L. The length of the absorbent article 10 in the front-rear direction L can be shortened, and the absorbent article 10 can be stored compactly before use.

図２に示すように、包装体１は、仮接合部５０を有してよい。仮接合部５０は、吸収性物品１０と包装シート１００にそれぞれ当接し、使用前の包装状態において吸収性物品１０と包装シートを仮接合する。仮接合部５０を設けることにより、包装シート１００によって吸収性物品１０が折り畳まれた状態を維持でき、使用前によりコンパクトに収容できる。また、仮接合部５０によって包装シート１００と吸収性物品１０の相対位置を固定でき、安定して折り畳むことができる。仮接合部５０の包装シート１００に対する接合強度は、仮接合部５０の吸収性物品１０に対する接合強度よりも高い。仮接合部５０は、包装シート１００に対する接合強度が高く、かつ吸収性物品に１０対する接合強度が低い。そのため、使用時に包装シート１００から吸収性物品１０を剥がした際に、包装シート１００側に仮接合部５０が残りやすい。使用時に吸収性物品１０に仮接合部５０が付着していないため、使用時に吸収性物品１０の非肌面側に仮接合部５０が配置されることに起因する違和感を抑制できる。 As shown in FIG. 2 , the package 1 may have temporary joints 50 . The temporary joining portion 50 abuts on the absorbent article 10 and the packaging sheet 100 respectively, and temporarily joins the absorbent article 10 and the packaging sheet in the packaged state before use. By providing the temporary joint portion 50, the folded state of the absorbent article 10 can be maintained by the packaging sheet 100, and the absorbent article 10 can be stored more compactly before use. In addition, the temporary joint portion 50 can fix the relative positions of the packaging sheet 100 and the absorbent article 10, so that the absorbent article 10 can be stably folded. The joint strength of the temporary joint portion 50 to the packaging sheet 100 is higher than the joint strength of the temporary joint portion 50 to the absorbent article 10 . The temporary joint portion 50 has a high joint strength to the packaging sheet 100 and a low joint strength to the absorbent article 10 . Therefore, when the absorbent article 10 is peeled off from the packaging sheet 100 during use, the temporary joint portion 50 tends to remain on the packaging sheet 100 side. Since the temporary joints 50 are not attached to the absorbent article 10 during use, it is possible to suppress discomfort due to the provisional joints 50 being arranged on the non-skin surface side of the absorbent article 10 during use.

仮接合部５０は、吸収性物品の非肌面と、包装シート１００の内面（吸収性物品側の面）と、を仮接合してよい。仮接合部５０は、少なくとも１個設けられていてよいが、好適には、前後方向Ｌに離間して複数設けられ、幅方向Ｗに離間して複数設けられてよい。仮接合部５０は、ホットメルト型接着剤等の接着剤であってもよいし、フック部材等のメカニカルファスナであってもよい。例えば、包装シートの内面に、フック部材を有するフックシートを接合し、フック部が吸収性物品の非肌側シート２５を構成する不織布に仮接合するように構成してよい。 The temporary joining portion 50 may temporarily join the non-skin surface of the absorbent article and the inner surface of the packaging sheet 100 (surface on the absorbent article side). At least one temporary joint portion 50 may be provided, but preferably, a plurality of temporary joint portions 50 may be provided spaced apart in the front-rear direction L, and a plurality of temporary joint portions 50 may be provided spaced apart in the width direction W. The temporary joint 50 may be an adhesive such as a hot-melt adhesive, or may be a mechanical fastener such as a hook member. For example, a hook sheet having a hook member may be joined to the inner surface of the packaging sheet, and the hook portion may be temporarily joined to the nonwoven fabric forming the non-skin side sheet 25 of the absorbent article.

仮接合部５０は、吸収コア３１と重なる領域に配置されてよい。吸収コア３１は、吸収性物品１０の中でも剛性が高い部材である。比較的剛性が高い吸収コア３１と重なる領域を、仮接合部５０によって包装シート１００に固定することにより、吸収性物品１０と包装シート１００の位置を安定させることができる。本実施の形態の仮接合部５０は、４個設けられており、吸収コア３１の幅方向Ｗの中心３１ＷＣに対する両側、かつ吸収コア３１の前後方向Ｌの中心３１ＬＣに対する両側に、それぞれ設けられている。 The temporary joint portion 50 may be arranged in a region overlapping the absorbent core 31 . The absorbent core 31 is a highly rigid member of the absorbent article 10 . By fixing the region overlapping with the absorbent core 31 having relatively high rigidity to the packaging sheet 100 by the temporary joint portion 50, the positions of the absorbent article 10 and the packaging sheet 100 can be stabilized. Four temporary joints 50 of the present embodiment are provided on both sides of the center 31WC in the width direction W of the absorbent core 31 and on both sides of the center 31LC in the front-rear direction L of the absorbent core 31. there is

幅折り目ＦＷは、防漏ギャザー６０の起立部６３の前後方向Ｌの中心を挟んで一対で配置されてよい。防漏ギャザー６０の起立部６３の前後方向Ｌの中心は、防漏弾性部材６１が収縮状態で配置された領域の前後方向Ｌの中心であってもよいし、後固定部６４Ａの前端縁と前固定部６４Ｃの後端縁との間隔の前後方向Ｌの中心であってもよい。仮接合部５０の少なくとも一部は、幅折り目ＦＷよりも前後方向Ｌの外側にそれぞれ配置されてよい。より詳細には、第１幅折り目ＦＷ１は、防漏ギャザー６０の起立部６３の前後方向Ｌの中心よりも後側に位置する。第１幅折り目ＦＷ１よりも後側に、４つの仮接合部５０のうち２つの仮接合部が配置されている。第２幅折り目ＦＷ２は、第１幅折り目ＦＷ１よりも前側に位置し、防漏ギャザー６０の起立部６３の前後方向Ｌの中心よりも前側に位置する。第２幅折り目ＦＷ２よりも前側に、４つの仮接合部５０のうち２つの仮接合部５０が配置されている。吸収性物品１０において仮接合部５０と重なる領域は、使用時に展開した状態において包装シート１００側に引っ張られる力がかかる。防漏ギャザー６０の起立部６３の前後方向Ｌの中心よりも前後方向Ｌの外側に、仮接合部５０が配置されているため、仮接合部５０を介して包装シート１００側に引っ張られる。このとき、仮接合部５０が幅折り目ＦＷよりも外側に配置されているため、幅折り目ＦＷを基点として幅折り目ＦＷよりも前後方向Ｌの外側の領域がより展開し易い。よって、幅折り目ＦＷ間に位置する起立部６３が立ち上がり易くなる。防漏ギャザー６０の起立性が向上することにより、横漏れをより抑制できる。 The width creases FW may be arranged as a pair across the center of the upright portion 63 of the leak-proof gather 60 in the front-rear direction L. The center in the front-rear direction L of the upright portion 63 of the leak-proof gather 60 may be the center in the front-rear direction L of the region where the leak-proof elastic member 61 is arranged in a contracted state, or may be aligned with the front edge of the rear fixing portion 64A. It may be the center in the front-rear direction L of the distance from the rear edge of the front fixing portion 64C. At least part of the temporary joint portion 50 may be arranged outside the width fold line FW in the front-rear direction L, respectively. More specifically, the first width crease FW1 is located on the rear side of the center of the upright portion 63 of the leak-proof gather 60 in the front-rear direction L. As shown in FIG. Two of the four temporary joints 50 are arranged behind the first width crease FW1. The second width crease FW2 is located forward of the first width crease FW1 and forward of the center of the upright portion 63 of the leak-proof gather 60 in the front-rear direction L. Two of the four temporary joints 50 are arranged on the front side of the second width crease FW2. A region of the absorbent article 10 that overlaps the temporary joint portion 50 is subjected to a pulling force toward the packaging sheet 100 when the absorbent article 10 is unfolded during use. Since the temporary joint portion 50 is arranged outside the center in the front-rear direction L of the standing portion 63 of the leak-proof gather 60 in the front-rear direction L, the temporary joint portion 50 is pulled toward the packaging sheet 100 side. At this time, since the temporary joint portion 50 is arranged outside the width fold line FW, the area outside the width fold line FW in the front-rear direction L is more likely to develop with the width fold line FW as a base point. Therefore, the standing portion 63 located between the width creases FW can be easily raised. Side leakage can be further suppressed by improving the uprightness of the leakage prevention gathers 60 .

仮接合部５０の少なくとも一部は、展開状態において、防漏ギャザー６０の起立部６３よりも前後方向Ｌの外側に位置してよい。仮接合部５０は、起立部６３全体に対する前後方向の外側に位置してもよいし、防漏弾性部材６１が収縮状態で配置された領域よりも前後方向Ｌの外側に位置してよい。この構成によれば、吸収性物品において仮接合部５０と重なる領域は、展開状態において包装シート１００側に引っ張られる力がかかる。防漏ギャザー６０の起立部６３よりも前後方向Ｌの外側の領域が、仮接合部５０を介して包装シート１００側に引っ張られることにより、起立部６３が立ち上がり易くなる。防漏ギャザー６０の起立性が向上することにより、横漏れをより抑制できる。 At least part of the temporary joint portion 50 may be positioned outside in the front-rear direction L of the upright portion 63 of the leak-proof gathers 60 in the unfolded state. The temporary joint portion 50 may be positioned outside the entire standing portion 63 in the front-rear direction, or may be positioned outside in the front-rear direction L from the area where the leak-proof elastic member 61 is arranged in the contracted state. According to this structure, the area|region which overlaps with the temporary joint part 50 in an absorbent article receives the force pulled to the packaging sheet 100 side in an unfolded state. A region of the leak-proof gathers 60 outside the upright portion 63 in the front-rear direction L is pulled toward the packaging sheet 100 via the temporary joint portion 50 , thereby making the upright portion 63 easier to rise. Side leakage can be further suppressed by improving the uprightness of the leakage prevention gathers 60 .
