【発明の属する技術分野】
【0002】
本願発明は、後処理テープおよび使い捨ておむつに関するものである。
【従来の技術】
【0003】
使用済みの使い捨ておむつ等を丸めて処理する際に用いられる後処理テープとしては、三重に折り畳まれてZ字状に構成されたものが従来からよく知られている(例えば、特許文献1参照)。
【0004】
上記構成の後処理テープTは、図4に示すように、被処理物(例えば、使い捨ておむつA)のバックシートに粘着剤Bを介して接着された固定部1と、該固定部1の一端において折り返された第1接続部1aに連結され且つ前記固定部1の表面に対して粘着剤Bを介して接着された第1展開部2と、該第1展開部2の一端において折り返された第1接続部2aに連結され且つ前記第1展開部2の表面の表面に対して粘着剤Bを介して接着された第2展開部3と、該第2展開部3の先端に設けられた摘まみ部4とからなっており、前記第1展開部2には、ウエスト側W方向に大きく延設された延設部2bが形成される一方、前記第2展開部3には、股側K方向に若干延設された延設部3aが形成されている。
【0005】
そして、この後処理テープTは、摘まみ部4を矢印Pの方向に持ち上げ、第2および第1展開部2,3を剥がして展開し、図5に示すように、丸めた使い捨ておむつAの股側Kに第2展開部3を接着させることにより、使い捨ておむつAを丸めた状態に保持し得るように作用することとなっている。このようにすると、使い捨ておむつAがかさばることなく容易に処理できるのである。

【発明が解決しようとする課題】
【0007】
ところが、上記構成の従来の後処理テープTの場合、第1および第2接続部1a,2aと固定部1および第1展開部2との間は、折り返されているため粘着剤の塗布が難しい部分であり、粘着剤が存在していない非接着部Cとなっている。このような構造の場合、摘まみ部4をもって第2および第1展開部2,3を剥がす時、第1接続部1aの固定部1側の面が、第1および第2展開部2,3に引っ張られて変形し、該変形に伴って固定部1が被処理物Aから浮いて剥がれてしまうおそれがある。特に、被処理物Aが柔らかな材質である不織布からなるバックシートであると、上記した固定部1の剥がれが頻繁に起こるおそれがある。このような固定部1の剥がれ現象は、後処理テープTによる処理を不能に陥らせるところから、改善が待たれている。
【0008】
本願発明は、上記の点に鑑みてなされたもので、展開時に被処理物から剥がれることのないようにすることを目的としている。
【課題を解決するための手段】
【0009】
本願発明では、上記課題を解決するための第1の手段として、被処理物に粘着剤を介して接着された固定部と、該固定部一端において折り返されて形成された第1接続部と、該第1接続部に連結され且つ前記固定部の表面に対して粘着剤を介して接着された第1展開部と、該第1展開部一端において折り返されて形成された第2接続部と、該第2接続部に連結され且つ前記第1展開部の表面に対して粘着剤を介して接着された第2展開部と、該第2展開部の先端に設けられた摘まみ部とからなり、前記第1展開部が前記摘まみ部側に延設された第1の延設部を有して構成される一方、前記第2展開部が前記摘まみ部と反対側に延設され且つ前記固定部に接着される第2の延設部を有して構成された後処理テープにおいて、前記第1接続部の前記固定部側の面と前記固定部の表面と、および前記第2接続部の前記第1展開部側の面と前記第1展開部の表面とを同一の粘着剤を介してそれぞれ接着して、前記後処理テープの各部の層間において、前記摘まみ部を除き非接着部を有さないように積層している。
【0010】
上記のように構成したことにより、第1展開部が摘まみ部側に延設された第1の延設部を有して構成される一方、第2展開部が摘まみ部と反対側に延設され且つ固定部に接着される第2の延設部を有して構成されていることに加えて、第1接続部の前記固定部側の面と前記固定部の表面と、および前記第2接続部の前記第1展開部側の面と前記第1展開部の表面とが同一の粘着剤を介して接着されて、後処理テープの各部の層間において、摘まみ部を除き非接着部を有さないように積層されることとなるので、摘まみ部を持ち上げて第2および第1展開部を剥がす時、第1接続部の固定部側の面が、第1および第2展開部に引っ張られて変形することがなくなる。従って、固定部と被処理物との接着部分が剥がれてしまうということがなくなるのである。つまり、後処理テープとしての機能を常時発揮できることとなるのである。
【0011】
本願発明では、上記課題を解決するための第2の手段として、液透過性のトップシートと、液不透過性のバックシートと、該バックシートと前記トップシートとの間に介在された吸収体とからなり、前記バックシートの適所に後処理テープを設けてなる使い捨ておむつにおいて、前記後処理テープを、前記バックシートに粘着剤を介して接着され且つウエスト側から股側に向かって延びる固定部と、該固定部ウエスト側一端において折り返されて形成された第1接続部と、該第1接続部に連結され且つ前記固定部の表面に対して粘着剤を介して接着された第1展開部と、該第1展開部股側一端において折り返されて形成された第2接続部と、該第2接続部に連結され且つ前記第1展開部の表面に対して粘着剤を介して接着された第2展開部と、該第2展開部の先端に設けられた摘まみ部とによって構成し、前記第1展開部がウエスト側に延設され且つ前記バックシートに接着される第1の延設部を有して構成される一方、前記第2展開部が股側に延設され且つ前記固定部に接着される第2の延設部を有して構成されるとともに、前記第1接続部の前記固定部側の面と前記固定部の表面と、および前記第2接続部の前記第1展開部側の面と前記第1展開部の表面とを同一の粘着剤を介して接着して、前記後処理テープの各部の層間において、前記摘まみ部を除き非接着部を有さないように積層している。
【0012】
上記のように構成したことにより、第1展開部がウエスト側に延設され且つ前記バックシートに接着される第1の延設部を有して構成される一方、第2展開部が股側に延設され且つ固定部に接着される第2の延設部を有して構成されていることに加えて、第1接続部の前記固定部側の面と前記固定部の表面と、および前記第2接続部の前記第1展開部側の面と前記第1展開部の表面とが同一の粘着剤を介して接着されて、後処理テープの各部の層間において、摘まみ部を除き非接着部を有さないように積層されることとなるので、摘まみ部を持ち上げて第2および第1展開部を剥がす時、第1接続部の固定部側の面が、第1および第2展開部に引っ張られて変形することがなくなる。従って、固定部と柔らかな材質(即ち、不織布)からなるバックシートとの接着部分が剥がれてしまうということがなくなるのである。つまり、後処理テープとしての機能を常時発揮できることとなるのである。
【発明の実施の形態】
【0013】
以下、添付の図面を参照して、本願発明の好適な実施の形態について説明する。
【0014】
この後処理テープTは、図1に示すように、使い捨ておむつAの後処理用として使用されるものである。
【0015】
前記使い捨ておむつAは、液透過性のトップシート11と、液不透過性のバックシート12と、該バックシート12と前記トップシート11との間に介在された吸収体13とを備えて構成されている。
【0016】
前記後処理テープTは、被処理物である使い捨ておむつAのバックシート12における適所(例えば、後見頃における左右方向中央部であってウエスト側Wに寄った位置)に取り付けられており、前記バックシート12に粘着剤Bを介して接着され且つウエストW側から股側Kに向かって延びる固定部1と、該固定部1のウエストW側一端において折り返されて形成された第1接続部1aと、該第1接続部1aに連結され且つ前記固定部1の表面に対して粘着剤Bを介して接着された第1展開部2と、該第1展開部2の股K側一端において折り返されて形成された第2接続部2aと、該第2接続部2aに連結され且つ前記第1展開部2の表面に対して粘着剤Bを介して接着された第2展開部3と、該第2展開部3の先端に設けられた摘まみ部4とによって構成されており、前記第1展開部2には、ウエスト側W方向(即ち、前記摘まみ部4側)に大きく延設され且つ前記バックシート12に接着される第1の延設部2bが形成される一方、前記第2展開部3には、股側K方向(即ち、前記摘まみ部4と反対側)に若干延設され且つ前記固定部1に接着される第2の延設部3aが形成されている。
【0017】
そして、前記第1接続部1aの前記固定部1側の面と前記固定部1の表面と、および第2接続部2aの前記第1展開部2側の面と前記第1展開部2の表面とは同一の粘着剤Bを介して接着されており、前記後処理テープの各部の層間において、前記摘まみ部4を除き非接着部を有さないように積層されている。
【0018】
この後処理テープTは、前述したように、摘まみ部4を矢印Pの方向に持ち上げ、第2および第1展開部2,3を剥がして展開し、丸めた使い捨ておむつAの股側Kに第2展開部3を接着させることにより、使い捨ておむつAを丸めた状態に保持し得るように作用することとなっている(図5参照)。このようにすると、使い捨ておむつAがかさばることなく容易に処理できるのである。
【0019】
本実施の形態においては、第1展開部2がウエスト側(即ち、摘まみ部4側)に延設され且つバックシート12に接着される第1の延設部2bを有して構成される一方、第2展開部3が股側(即ち、摘まみ部4と反対側)に延設され且つ固定部1に接着される第2の延設部3aを有して構成されていることに加えて、第1接続部1aの前記固定部1側の面と前記固定部1の表面と、および第2接続部2aの前記第1展開部2側の面と前記第1展開部2の表面とが同一の粘着剤Bを介して接着されて、前記後処理テープの各部の層間において、摘まみ部4を除き非接着部を有さないように積層されているので、摘まみ部4を持ち上げて第2および第1展開部3,2を剥がす時、第1接続部1aの固定部1側の面が、第1および第2展開部2,3に引っ張られて変形することがなくなる。従って、固定部1と柔らかな材質(即ち、不織布)からなるバックシート12との接着部分が剥がれてしまうということがなくなるのである。つまり、後処理テープとしての機能を常時発揮できることとなるのである。
【0020】
ちなみに、前記第1接続部1aに使用される粘着剤Bの糊厚および糊幅を変えた実施例1〜4および比較例1、2について、剥離強度および剥がれ枚数(100枚中)を測定したところ、表1に示す結果が得られた。なお、上記測定は、折り返し部分の両端をストログラフのチャックで固定し、そのときに出た剥離強度のピークを読むことにより行った。
【0021】
【表1】

Figure 0004244297
【0022】
上記結果によれば、糊厚は20μm以上、糊幅は6.0mm以上とするのが望ましいことが分かる。
【0023】
なお、この後処理テープは、使い捨ておむつ以外の吸収性物品にも適用可能である。

BACKGROUND OF THE INVENTION
[0002]
The present invention relates to a post-processing tape and a disposable diaper.
[Prior art]
[0003]
As a post-processing tape used when rounding and processing a used disposable diaper or the like, a tape that is folded in triplicate and configured in a Z shape has been well known (see, for example, Patent Document 1). .
[0004]
As shown in FIG. 4, the post-processing tape T having the above configuration includes a fixing portion 1 bonded to a back sheet of an object to be processed (for example, a disposable diaper A) via an adhesive B, and one end of the fixing portion 1. The first unfolded portion 2 connected to the first connecting portion 1a folded back and bonded to the surface of the fixed portion 1 via the adhesive B, and folded at one end of the first unfolded portion 2 A second unfolding portion 3 connected to the first connecting portion 2a and bonded to the surface of the surface of the first unfolding portion 2 via an adhesive B; and provided at the tip of the second unfolding portion 3 The first unfolded portion 2 is formed with an extended portion 2b that extends greatly in the waist side W direction, while the second unfolded portion 3 has a crotch side. An extending portion 3a that extends slightly in the K direction is formed.
[0005]
And this post-processing tape T lifts the knob | pick part 4 in the direction of arrow P, peels off the 2nd and 1st expansion | deployment parts 2 and 3, and expands, as shown in FIG.

JP2001-258938.
[Problems to be solved by the invention]
[0007]
However, in the case of the conventional post-processing tape T having the above-described configuration, it is difficult to apply the adhesive because the first and second connecting portions 1a and 2a and the fixing portion 1 and the first developing portion 2 are folded back. This is a non-adhesive part C which is a part and does not have an adhesive. In the case of such a structure, when the second and first development parts 2 and 3 are peeled off with the knob part 4, the surface of the first connection part 1a on the fixed part 1 side is the first and second development parts 2 and 3. There is a possibility that the fixing portion 1 is lifted from the workpiece A and peeled off along with the deformation. In particular, if the workpiece A is a back sheet made of a non-woven fabric that is a soft material, the fixing part 1 may be peeled off frequently. Such a peeling phenomenon of the fixing portion 1 is expected to be improved because it makes the processing by the post-processing tape T impossible.
