Description

本発明は、低コストで、装着性及び着用感に優れる、パンツタイプ吸収性物品及びその製造方法に関する。 The present invention relates to a pants-type absorbent article that is low in cost and excellent in wearability and wearing feeling, and a method for manufacturing the same.

従来、幼児、成人及び病人の排泄物を吸収するため、パンツ型の紙おむつ（パンツタイプ吸収性物品）が使用されている。パンツタイプ吸収性物品は、ウエスト開口部と一対のレッグ開口部とを形成するとともに、排泄物を吸収する吸収性本体とその支持部材である外装体を有し、吸収性本体が前後から着用者の股間部を覆っている。そして、レッグ開口部に着用者の両足を入れ、紙おむつ本体を胴回りへ引っ張り上げて着用する。 Conventionally, pants-type disposable diapers (pants-type absorbent articles) have been used to absorb the excrement of infants, adults, and sick people. The pants-type absorbent article has a waist opening and a pair of leg openings, and has an absorbent main body that absorbs excrement and an exterior body that is a supporting member thereof, and the absorbent main body is worn by the wearer from the front and rear. Covering the crotch. And a wearer's both legs are put in a leg opening part, and a paper diaper main body is pulled up to a trunk periphery and it wears.

このようなパンツタイプ吸収性物品においては、幼児用及び成人用ともに、着用者の体型に応じて、様々なサイズの商品が販売されており、例えば、サイズに応じて小さいものから順に、幼児用としては、ＳＳ、Ｓ、Ｍ、Ｌ、ＸＬ（ＢＩＧ）、ＢＩＧより大きいスーパーＢＩＧの６種類、成人用としては、ＳＳ、Ｓ、Ｓ−Ｍ（ＳとＭの中間サイズ）、Ｍ、Ｍ−Ｌ（ＭとＬの中間サイズ）、Ｌ、ＬＬの７種類、のサイズに分類される。 In such a pants-type absorbent article, products of various sizes are sold for both infants and adults, depending on the wearer's body shape, for example, for infants in order from the smallest according to size. As SS, S, M, L, XL (BIG), 6 types of Super BIG larger than BIG, for adults, SS, S, SM (intermediate size of S and M), M, M- The size is classified into L (intermediate size between M and L), L, and LL.

ここで、特に、成人用の場合には、着用者のウエスト回り、胴回り、レッグ回りの体型は、男性と女性に大きな差があり、画一的なサイズ構成では、全ての体型に適合させることが困難であった。また、成人用のパンツタイプ吸収性物品をアウターとして、専用の尿取りパッドを併用する場合も増えてきており、この場合、アウターの中に装着する尿取りパッドのサイズや厚さ及び着用者の体型を考慮して、アウターであるパンツタイプ吸収性物品のサイズを選択しなければならないため、従来の画一的なパンツタイプ吸収性物品のサイズ構成では、これらの使用実態に適しているとは言い難く、更に多様なサイズのパンツタイプ吸収性物品の供給が求められている。 Here, especially in the case of adults, the wearer's waist, waist, and leg body shapes differ greatly between men and women, and in a uniform size configuration, all body shapes should be adapted. It was difficult. In addition, an increasing number of adult pants-type absorbent articles are used as outerwear, and a dedicated urine-absorbing pad is also used. In this case, the size and thickness of the urine-taking pad to be worn in the outerwear and the wearer's Considering the body shape, the size of the pants-type absorbent article that is the outer must be selected, so the conventional uniform pants-type absorbent article size configuration is suitable for these actual usage It is difficult to say, and there is a demand for the supply of pant-type absorbent articles of various sizes.

一方で、種々のサイズの製品を製造するためには、各サイズごとに製品寸法が異なるため、各サイズごとに適した専用機により製造するか、１台で複数のサイズのパンツタイプ吸収性物品を製造することが行わなわければならない。しかし、サイズごとの専用機を設けることは、多大な設備投資が伴うものであり、逆に、１台の製造設備で複数のサイズを製造する場合には、各サイズチェンジのための作業労力、調整にかかる時間、資材ロス等が膨大となり、製造コストに多大な影響をもたらすことになる。よって、一つのサイズで、複数のサイズをカバーできるパンツタイプ吸収性物品の検討がなされている。 On the other hand, in order to manufacture products of various sizes, since the product dimensions are different for each size, it is manufactured by a dedicated machine suitable for each size, or a pants type absorbent article of a plurality of sizes in one unit Manufacturing must be done. However, providing a dedicated machine for each size involves a large amount of capital investment. Conversely, when manufacturing multiple sizes with one manufacturing facility, the work effort for each size change, Adjustment time, material loss, and the like become enormous, resulting in a significant impact on manufacturing costs. Therefore, examination of the underpants type absorbent article which can cover several size by one size is made | formed.

このような検討がなされてきたパンツタイプ吸収性物品として、特許文献１には、パンツタイプ吸収性物品の左右両腰に対応した各接合位置の間隔を変更することによって、胴回り周長及びレッグ回り周長の異なるパンツタイプ吸収性物品を製造することを特徴とするパンツタイプ吸収性物品の製造方法が開示されている。また、特許文献２には、パンツタイプ吸収性物品の両側部のウエスト開口部近傍およびレッグ開口部近傍の外表面に、パンツタイプ吸収性物品の他の外表面と着脱自在で、ウエスト開口サイズ又はレッグ開口サイズを調節可能な締結手段を設けたパンツタイプ吸収性物品が開示されている。さらに、特許文献３には、パンツタイプ吸収性物品のウエスト開口部とレッグ開口部の上端との間に位置する胴回り部のうち、両側部に、胴回り方向の一部の範囲として定まるマチ部がそれぞれ設けられるとともに、両端部がマチ部の胴回り方向一方側及び他方側にそれぞれ固定された固定部が設けられたパンツタイプ吸収性物品が開示されている。 As a pants-type absorbent article that has been studied as described above, Patent Document 1 discloses that the circumference of the waistline and the leg circumference are changed by changing the interval between the joint positions corresponding to the left and right hips of the pants-type absorbent article. A method for producing a pants-type absorbent article, characterized by producing pants-type absorbent articles having different perimeters, is disclosed. Further, in Patent Document 2, the outer surface in the vicinity of the waist opening and the leg opening in both sides of the pant-type absorbent article is detachable from the other outer surface of the pant-type absorbent article, and the waist opening size or A pants-type absorbent article provided with fastening means capable of adjusting the leg opening size is disclosed. Furthermore, in Patent Document 3, there is a gusset portion defined as a partial range in the waistline direction on both sides of the waistline portion located between the waist opening of the pant-type absorbent article and the upper end of the leg opening. There is disclosed a pant-type absorbent article that is provided respectively, and that is provided with a fixing portion in which both end portions are respectively fixed to one side and the other side of the gusset portion in the waistline direction.

しかしながら、特許文献１から３に記載のパンツタイプ吸収性物品においても、サイズを調整する際には締結手段やマチ部の調整が必要であり、幼児用においては保護者が、成人用においては介護者が、調整を行わなければならない場合があり、装着性が十分ではないという問題があり、さらに、締結手段やマチ部を設けたことによる着用時の違和感が発生することがあり、着用感についても十分ではないという問題があった。そこで、本発明は、低コストで、装着性及び着用感に優れるパンツタイプ吸収性物品及びその製造方法を提供することを目的とする。 However, in the pants-type absorbent articles described in Patent Documents 1 to 3, it is necessary to adjust the fastening means and the gusset portion when adjusting the size, and a guardian for infants and a caregiver for adults. There are cases where the person has to make adjustments, and there is a problem that the wearability is not sufficient, and further discomfort during wearing due to the provision of fastening means and gussets may occur, There was also a problem that it was not enough. Therefore, an object of the present invention is to provide a pant-type absorbent article that is low in cost and excellent in wearability and wearing feeling and a method for producing the same.
