【従来の技術】Z状や二つ折りなどに折った不織布(ティッシュ)を複数枚積み重ねて容器内に収容し、使用時に容器から一枚ずつ取り出すようにした容器入りティッシュが従来から広く知られている。 BACKGROUND ART Z-shaped or clamshell like folded nonwoven (the tissue) is accommodated on a plurality stacked container, containers tissue which they were taken out one by one from the container during use is widely known from the prior art there. 容器入りティシュには、水性組成物で湿潤したいわゆるウエットタイプおよび湿潤されていないドライタイプの両方がある。 The containers tissue, there is both a dry type which is not wetted so-called wet-type and wet with an aqueous composition. 容器に収容したティッシュでは、一枚のティッシュを容器から取り出すと、それに続く次のティッシュまで一緒に取り出されてしまうという、いわゆる“ズル”が発生することがある。 The tissue was stored in the container, when taking out a piece of tissue from the container, that subsequent would retrieved together until the next tissue, so-called "nozzle" may occur. 特に、ウエットタイプのティシュは、ティシュが湿潤していてティッシュ間の分離性に劣るために、 In particular, tissue wet type, in order to poor tissue is not wetted separability between tissue,
前記した“ズル”が発生し易い。 Easy said was "cheating" is generated.

【0003】上記した“ズル”の発生を防止して、ティッシュを一枚ずつ容器から確実に取り出せるようにするために、水性組成物で湿潤したウエットティッシュ(不織布)の端部にエンボス加工を施すことが提案されている(特表2000−509315)。 [0003] by preventing the occurrence of the above "nozzle", the tissue in order to ensure that extractable from the container one by one, embossed on the end of the wet tissues (nonwoven) which is wetted with an aqueous composition it has been proposed (JP-T 2000-509315). しかしながら、この従来技術による場合は、エンボス加工により生じた凸部が角のあるエッジ状になっているため、一枚のウエットティッシュを容器から取り出す際に、それに続く次のウエットティッシュが引っ掛かって一緒に容器から取り出されてしまい易く、ウエットティッシュを一枚ずつ確実に容器から取り出すという目的の解決には十分に寄与していない。 However, according to this prior art, since the protrusions caused by embossing is in edged with corners, when taking out a piece of wet tissue from the container, followed caught the next wet tissue together the likely cause is removed from the container, not sufficiently contribute to solving the purpose of that taken from reliable container wet tissues one by one. しかも、このウエットティッシュでは、エンボス加工によって、押圧された部分の厚さが極端に薄くなっていることがあり、その場合には該ウエットティッシュを用いて汚物などを拭き取る際に、汚物がその薄い部分を通過してしまい、手などを汚すなどのトラブルが発生することがある。 Moreover, in this wet tissue, by embossing, may the thickness of the pressed portion is made extremely thin, when wiping the like waste with the wet tissue in the case, dirt that thin will pass through the part, problems such as dirty hands may occur.

【0004】また、容器からのティッシュを一枚ずつ確実に取り出し得るようにするために、容器の取り出し口を山型にしたりH型にすることが提案されている。 Further, in order that the tissue from the container may reliably taken out one by one, it has been proposed to H-type or the outlet of the container mound. しかしながら、この場合には、終わり部分のティッシュ、例えば90枚入りの場合は最後の2〜20枚程度のティッシュの取り出し時に、次のティッシュまで一緒に取り出されてしまうという上記した“ズル”が発生し易い。 However, in this case, the end portion of the tissue, upon retrieval of the last 2 to 20 sheets about tissue if for example the 90 pieces, was the "cheat" that would be taken out together until the next tissue generation easy to.
