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 and a method for producing the same, which is low in cost and excellent in wearability and wearing feeling.

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 excrement of infants, adults and the sick. The pants-type absorbent article has a waist opening and a pair of leg openings, and also has an absorbent body that absorbs excrement and an exterior body that is a support member thereof, and the absorbent body is worn from the front and back. It covers the crotch part of. Then, put both feet of the wearer in the leg opening and pull the body of the disposable diaper around the waist to wear it.

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 pants-type absorbent articles, products of various sizes are sold for both infants and adults according to the body shape of the wearer. For example, for infants in order from the smallest one according to the size. There are 6 types of SS, S, M, L, XL (BIG) and Super BIG larger than BIG, and for adults, SS, S, SM (intermediate size between S and M), M, M- It is classified into seven sizes, 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 for adults, there is a big difference in body shape around the waist, waist, and legs of the wearer between men and women, and in a uniform size configuration, it should be adapted to all body shapes. Was difficult. In addition, there is an increasing number of cases where a pants-type absorbent article for adults is used as an outer and a dedicated urine absorbing pad is also used. In this case, the size and thickness of the urine absorbing pad to be worn inside the outer and the wearer's Since the size of the outer pants-type absorbent article must be selected in consideration of the body shape, the size composition of the conventional uniform pants-type absorbent article is not suitable for these actual usage conditions. It is hard to say, and there is a demand for the supply of pants-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, the product dimensions are different for each size, so either manufacture with a dedicated machine suitable for each size, or one unit can be used for pants-type absorbent articles of multiple sizes. Must be manufactured. However, providing a dedicated machine for each size involves a large amount of capital investment, and conversely, when manufacturing multiple sizes with one manufacturing facility, the labor required for each size change is required. The time required for adjustment, material loss, etc. will be enormous, which will have a great impact on manufacturing costs. Therefore, a pants-type absorbent article that can cover a plurality of sizes with one size is being studied.

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 for which such studies have been made, Patent Document 1 describes the waist circumference and leg circumference by changing the distance between the joint positions corresponding to the left and right waists of the pants-type absorbent article. A method for manufacturing a pants-type absorbent article, which comprises producing a pants-type absorbent article having a different circumference, is disclosed. Further, Patent Document 2 describes that the outer surface of the pants-type absorbent article in the vicinity of the waist opening and the leg opening of both sides is detachable from other outer surfaces of the pants-type absorbent article, and has a waist opening size or. Disclosed are pants-type absorbent articles provided with fastening means that can adjust the leg opening size. Further, in Patent Document 3, of the waist circumference portion located between the waist opening and the upper end of the leg opening of the pants-type absorbent article, gusset portions defined as a part of the waist circumference direction are provided on both sides. Disclosed is a pants-type absorbent article in which both ends are provided and fixed portions are provided on one side and the other side of the gusset portion in the waist circumference direction, respectively.

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, even 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. There is a problem that the person may have to make adjustments and the wearability is not sufficient, and further, there may be a feeling of strangeness when wearing due to the provision of the fastening means and the gusset part. There was a problem that it was not enough. Therefore, an object of the present invention is to provide a pants-type absorbent article having excellent wearability and wearing feeling at low cost and a method for manufacturing the same.
