Description

[발명의 명칭]
보다 덜 신장가능한 차단부를 갖는 신장가능한 흡수 제품
[발명의 분야]
본 발명은 기저귀, 생리대, 팬티 라이너, 및 실금자 패드와 같은 흡수 제품에 관한 것이다. 더욱 구체적으로는, 본 발명은 액체 흐름에 대해 차단부로 작용하는 보다 덜 신장가능한 입술모양 차단부가 제공된, 신장가능한 흡수 제품, 예를들어 생리대에 관한 것이다.
[발명의 배경]
생리대, 팬티 라이너 및 실금자 패드와 같은 흡수 제품은 내의의 가랑이 영역에 전형적으로 착용하는 장치이다. 이러한 장치는 인체로부터의 액체 및 다른 분비물을 흡수 및 보유하고, 신체 및 의복이 더럽혀지는 것을 방지하도록 고안되어 있다. 이러한 흡수 제품의 물질 및 구조에서 많은 개선이 있었지만, 이들의 성능, 특히 흡수 제품의 누수 성능을 개선시키는 것은 계속 큰 사업으로 생각된다.
예를들어, 일회용 흡수 제품에는 이러한 제품의 측면 누수 성능을 개선시키기 위해 탄성 부재가 이미 제공되어 왔다. 예를들어, 1975년 1월 14일자로 부엘(Buell)에게 허여된 미합중국 특허 제 3,860,003 호는 탄성 부재가 상면시이트와 배면시이트사이에서 제품의 측면 플랩에 위치하는 탄성 일회용 흡수 제품을 기술한다. 측면 플랩은 탄성 부재에 의해 주름져서, 패드를 위한 보트형 구조가 존재하고 측면 플랩이 제품의 가장자리를 따라 차단부를 형성한다.
포르만(Foreman)에게 허여된 "차단 포켓을 갖는 흡수제품 (Absorbent Article Having A Containment Pocket)" 이란 발명의 명칭의 미합중국 특허 제 4,738,677 호는 흡수 제품의 종방향 가장자리를 따라 존재하는 차단 커프스의 제 1 세트 및 흡수 제품의 말단 가장자리를 따라 존재하는 차단 커프스의 제 2 세트를 포함하는, 액체 흐름에 대한 또다른 유형의 차단부를 기술한다. 차단 커프스는 차단 포켓을 형성하기 위해 모서리 지점에서 겹친다. 차단 커프스의 제 1 세트에는 흡수 제품의 액체-수용 표면으로부터 차단 커프스의 세트 모두를 이격시키는 이격 수단, 예를들어 탄성 부재가 제공되어 있다. 전형적으로, 상기 언급한 유형의 대부분의 일회용 흡수 제품(즉, 생리대, 팬티 라이너, 및 실금자 패드)은 신장되지 않는 물질로 제조되어 있다. 즉, 물질(및 제품 그 자체)은 흡수 제품을 착용하였을때 일반적으로 받는 힘의 존재하에서 신장되지 않을 것이다. 그러나, 최근에는 (제품이 내의 안에 착용하는 유형을 갖는 경우) 향상된 편안함과 순응성을 주는 신장가능한 흡수 제품을 착용자의 신체 및 내의에 제공하고자 노력한다. PCT 특허원 공개공보 제 93/01785 호 및 그의 상응하는 미합중국 특허 제 07/915,133 호(둘다 1992년 7월 23일자로 출원되었고, 본원의 연속-일부 출원이다)는 신장가능한 흡수 제품을 기술한다. 그러나, 상기 흡수 제품의 특징을 향상시키기 위한 연구는 계속 되고 있다.
특히, 액체 흐름에 대한 차단부가 제공된 신장가능한 흡수 제품, 예를들어 생리대가 필요하다.
따라서, 본 발명의 목적은 액체 흐름에 대한 차단부가 제공된 신장가능한 흡수 제품, 예를들어 생리대를 제공하는 것이다.
본 발명의 또다른 목적은 생리대보다 덜 신장가능하며 생리대가 신장될때 비교적 평평한 배치에서 더욱 직립형의 배치로 바뀌는 차단부가 제공된 신장가능한 흡수 제품, 예를들어 생리대를 제공하는 것이다.
본 발명의 상기 및 다른 목적은 하기 설명을 참조로 하고 첨부된 도면을 고려할때 더욱 명백할 것이다.
[발명의 요약]
본 발명은 생리대와 같은 흡수 제품을 제공한다. 본 발명의 생리대는 적어도 몇가지의 신장가능한 구성요소를 갖는다. 생리대에는 액체 흐름에 대한 보다 덜 신장가능한 차단부가 제공되어 있다.
생리대는 제 1 말단 영역, 제 2 말단 영역, 제 1 말단 영역과 제 2 말단 영역사이에 위치한 중심 영역, 및 생리대의 주변을 형성하는 한쌍의 종방향 측면 가장자리 및 말단 가장자리를 갖는다. 바람직한 양태에서, 생리대는 제 1 및 제 2 말단 영역보다 좁은 중심 영역을 갖는다(예를들어, 생리대는 모래시계형 또는 개뼈형일 수도 있다). 생리대는 바람직하게는 신장가능한 액체 투과성 상면시이트; 상면시이트에 결합한 신장가능한 액체 불투과성 배면시이트; 상면시이트와 배면시이트사이에 위치한 신장가능한 흡수 코어; 및 액체 흐름에 대해 차단부로 작용하는 보다 덜 신장가능한 액체 불투과성 입술모양 차단부를 포함한다. 이러한 바람직한 양태에서, 입술모양 차단부는 생리대의 종방향 측면 가장자리를 따라 상면시이트 위에 놓인 필름의 좁은 스트립을 포함한다. 스트립 각각은 내부 가장자리, 외부 가장자리 및 한쌍의 말단을 갖는다. 외부 가장자리는 내부 가장자리보다 생리대의 종방향 중심선으로부터 더 멀리 위치하고 있다. 스트립의 외부 가장자리 및 말단은 생리대의 주변을 따라 상면시이트에 고정되어 있다. 스트립의 내부 가장자리는 말단사이에서 상면시이트에 고정되어 있지 않다.
생리대가 신장가능하지 않는 경우, 스트립은 상면시이트에 대해 평평하게 놓여 있다. 생리대가 신장되는 경우, 스트립의 부착되지 않은 부분은 평평한 배치에서 더욱 직립형 배치로 바뀐다. 스트립은 상면시이트를 가로질러 액체의 흐름에 대해 차단부로 작용하는 생리대의 종방향 가장자리를 따라 내부로 대면한 입술모양(또는 가스켓)을 형성한다. 스트립의 들어올려짐은 차단 스트립의 부착된 가장자리 및 비부착된 가장자리와 관련된 차별적 신장성이 원인이다. 이러한 효과는 생리대가, 생리대의 중심 영역이 가장자리 영역보다 좁은 모래시계형 또는 개뼈형을 갖는 경우, 특히 두드러진다. 특히 바람직한 양태에서, 유사한 스트립이 또한 생리대의 전체 둘레를 따라 차단부를 형성하기 위해 생리대의 말단 가장자리를 따라 고정될 수 있다.
[도면의 간단한 설명]
본 명세서는 특히 강조되고 본 발명을 형성하는 것으로 간주되는 본 발명의 주제를 명백히 청구하는 특허청구범위를 포함하지만, 본 발명은 첨부된 도면을 고려한 하기 설명으로부터 보다 잘 이해될 것이라고 생각된다.

[발명의 상세한 설명]
제 1 내지 제 3 도에는 본 발명의 일회용 흡수 제품의 바람직한 실시양태가 나타나 있다. 본 발명은 액체 흐름에 대해 덜 신장가능한 차단부가 제공된 신장가능한 일회용 흡수 제품, 예를 들면 기저귀, 생리대, 팬티 라이너, 및 실금자용 패드에 관한 것이다.
예시된 실시 양태에서, 흡수 제품은 생리대 (20)이다. 본 원에 사용한 바와 같이, "생리대"란 용어는 여성들이 신체로부터 배설되는 각종 분비물(예를 들면 혈액, 생리혈, 및 뇨)을 흡수하여 함유하고자 고려된, 여성의 외음부 영역에 인접하게 착용하는 제품을 지칭한다. 그러나 본 발명은 또한 팬티 라이너와 같은 기타 여성 위생용품 또는 생리용 패드, 또는 실금자용 패드와 같은 기타 흡수 제품에 적용할 수 있음을 알아야한다.
생리대 (20)은 2개의 표면, 즉, 액체 투과성 신체-대향 표면 또는 "신체 대향면" (20A) 및 액체 불투과성 가멘트 대향면 (20B)을 갖는다. 제 1 도에서 생리대 (20)의 신체 대향면 (20A)를 나타내었다. 신체 대향면 (20A)는 착용자의 신체에 인접하게 착용한다. 제 2 도에 나타낸 생리대 (20)의 가멘트 대향면 (20B)는 반대편에 위치하고 생리대 (20)을 착용할 경우, 착용자의 내의에 인접하게 위치한다.
생리대 (20)은 2개의 중심선, 즉, 종방향 중심선 L 및 횡 방향 중심선 T를 갖는다. 본원에서, "종방향"이란 생리대 (20)을 착용한, 서있는 착용자의 신체를 왼쪽과 오른쪽으로 양분하는 수직 평면과 전체적으로 일렬이 되는(예를들면, 평행한) 생리대 (20)의 평면중의 선, 축 또는 방향을 의미한다. "횡방향"이란 일반적으로 종방향과 직각이 되는 생리대 (20)의 평면내에 위치하는 선, 축 또는 방향을 의미한다.
제 1 도는 생리대 (20)에 2개의 이격된 종방향 가장자리(또는 "측면 가장자리") (22), 및 2개의 이격된 횡방향 또는 말단 가장자리(또는 "말단") (24)를 갖고, 이들이 함께 생리대 (20)의 둘레 (26)을 형성한다는 것을 보여준다. 생리대(또는 그의 주본체부)는 또한 2개의 말단 영역을 갖는데, 이들을 제 1 말단 영역 (28)과 제 2 말단 영역 (30)으로 표시하였다. 중심 영역 (32)는 말단 영역 (28)과 (30)사이에 배치된다. 이러한 말단 영역 (28)과 (30)은 중심 영역 (32)의 가장자리로부터 주본체부의 길이의 약 1/8 내지 약 1/3으로 바깥쪽으로 신장된다. 중심 영역 (32)와 2개의 말단 영역 (28)과 (30)에 대한 상세한 설명은 1987년 9월 1일자로 히긴스(Higgins)에게 허여된 미합중국 특허 제 4,690,680호중에 기술되어 있다.
생리대 (20)는 비교적 두껍거나 비교적 얇거나 또는 매우 얇은 것을 포함하여 임의의 두께를 가질 수 있다. 제 1 도 내지 제 3 도 중에 나타낸 생리대 (20)의 실시양태는 비교적 얇은, 바람직하게는 "초박형" 생리대를 예시하려는 것이다. 그러나, 이러한 도면에서 볼 경우, 도면에서 나타낸 물질의 다수의 층으로 인해 생리대 (20)이 실제보다 훨씬 두껍게 보인다는 것을 이해하여야 한다. 오스본(Osborn)에게 허여된 미합중국 특허 제 4,950,264 호 및 제 5,009,653 호중에 기술된 바와 같은 "초박형" 생리대 (20)은 바람직하게는 약 3 mm미만의 캘리퍼를 갖는다. 이러한 얇은 생리대 (20)은 또한, 착용자가 편안함을 느낄 수 있도록 바람직하게는 가요성을 가져야 한다.
제 2 도는 본 발명의 생리대 (20)의 개별적인 구성요소를 보여준다. 제 2 도중에 나타낸 생리대 (20)은 일반적으로 4개이상의 주 구성요소를 포함한다. 이는 액체 투과성 상면시이트 (38), 액체 불투과성 배면시이트 (40), 상면시이트 (38)과 배면시이트 (40)사이에 위치한 흡수코어 (42) 및 생리대의 측면 가장자리(22)를 따라 액체의 흐름을 차단하는 하나 이상의 차단부, 바람직하게는 한쌍의 차단부 (44)를 포함한다. 또한 제 1 내지 제 3 도에 나타낸 바람직한 실시양태는 신장력에 응하여 굴절되는(또한 바람직하게는 들어올려져서 개선된 신체 접촉성을 제공하는)중심 영역 (32)에 위치하는 덜 신장가능한 요소 (216)를 포함한다. 차단부가 부착된 생리대는 PCT 공개공보 제 WO 93/01785 호 및 제 93/01786 호)중에 기술된 것중 하나일 수 있고, 하나이상의 신장가능한 구성요소로 이루어지고 보다 바람직하게는 모든 신장가능한 구성요소(덜 신장가능한 요소는 제외)로 이루어져 있고 전체적으로 신장성을 갖는다.
생리대 (20)의 신장성을 제 6 도에 간단하게 나타내었다. 본 원에서, "신장성"이란 x-y 평면에서 하나이상의 방향으로 크기가 증가할 수 있는 제품을 의미한다. x-y 평면은 전체적으로 생리대 (20)의 면에 평행한 평면이다. 신장가능한 이란 용어는 신축성 있는 및 탄성적으로 신축성있는 제품을 포함한다(하기 정의됨). 제 6 도중에 나타낸 생리대 (20)은 바람직하게는 길이와 폭 모두가 신장가능하다. 그러나, 다른 실시양태에서, 생리대 (20)은 이러한 방향중 단지 하나의 방향으로만 신장될 수도 있다. 바람직하게는, 생리대 (20)는 적어도 종방향으로는 신장가능하다.
몇가지 바람직한 실시 양태에서, 생리대 (20)은 신장성외에 신축성을 갖는다. 본원에서, "신축성"이란 제품에 신장력을 적용시킬 경우 제품이 신장되고 또한 신장력에 대한 얼마간의 저항을 제공하는 제품의 특성을 의미한다. 더욱 바람직하게는, 생리대 (20)은 탄성적으로 신축될 수도 있다. 본원에서 "탄성적으로 신장가능한" 또는 "탄성적으로 신축가능한"이란 동일한 의미를 갖는다. 이러한 용어는 신장력을 제거할 경우, 생리대가 신장되지 않은 크기(또는 "원래의" 크기)로 복원되는 성질을 의미한다. 그러나, 생리대 (20)가 항상 신장되지 않은 크기로 복원될 필요는 없다. 제 6 도에 나타낸 바와 같이, 생리대 (20)은 신장되지 않은 크기 LS와 신장된(또는 신축된) 크기 WS사이의 이완된 크기(LR및 WR)로 복원될 수도 있다. 생리대를 탄성적으로 신장가능하도록 제조함으로써 생리대를 신장시키는 힘을 제거할 경우 생리대가 종방향으로 안쪽으로 구겨지는(즉, 종방향으로 뭉쳐지는) 바람직하지 못한 경향이 감소된다. 이는 착용자의 팬티가 수축될 경우 특히 그러하다.
생리대 (20)은 PCT 국제 특허출원 제 W093/01785 호 및 제 W0/01786 호에 기술된 정도로 신장되는 것이 바람직하다. 요약하면, 생리대는 팬티에 생리대를 착용할 때 드는 힘하에서 약 5 내지 50%, 바람직하게는 약 10 내지 약 40%, 더욱 바람직하게는 약 25 내지 약 40% 정도 신장될 수 있는 것이 바람직하다. 생리대는 약 50 ~ 100 g 내지 약 1000 ~ 1500 g 의 힘, 더욱 바람직하게는 약 250 내지 약 800 g의 힘하에서 이와 같이 신장될 수 있는 것이 바람직하다. 기타 바람직한 신장도는 표 1 에 제시되어 있다(제 7 도). 표에 특정된 모든 한계 및 범위는 특정된 한계 및 범위내에 있는 모든 좁은 한계, 범위 및 정도를 포함하는 것으로 인식하여야 한다. 본 발명의 생리대는 또한 생리대에 적용되는 힘의 양을 실질적으로 증가시키지 않고 특정 양을 넘어 신장되는 것을 방지하는 "강제벽(force wall)"이 제공될 수 있는 구조를 포함하여, 상기 문헌에 기술된 생리대의 기타 특징이 제공될 수 있다.
본 발명의 생리대 (20) 의 각 구성요소는 제 1 내지 3 도를 참조하여 좀더 상세히 기술될 것이다.
상면시이트 (38)은 제 1 액체 투과성 구성요소를 포함한다. 상면시이트 (38) 은 생리대 (20)의 사용시, 착용자의 피부에 근접하게 위치한다. 상면시이트 (38)은 바람직하게는 가능한한 유연하고, 부드러운 촉감을 부여하고, 착용자의 피부에 자극을 주지않는다. 또한, 상면시이트 (38)은 신체 분비물이 상면시이트를 신속하게 투과하고 흡수 구조물 (42)를 향해 유동하지만, 이러한 분비물이 상면시이트 (38)을 통해 착용자의 피부로 역류하지 않도록, 양호한 투과성과 감소된 재습윤성을 가져야 한다.
상면시이트 (38)은 신체-접촉면 (38A)와 의류-접촉면(또는 코어-접촉면)(38B)를 포함하는 2개의 측면(또는 면 또는 표면)를 갖는다. 상면시이트 (38)의 신체-접촉면 (38A)는 일반적으로 생리대 (20)의 신체-접촉면("신체 표면") (20A)의 적어도 일부를 형성한다. 상면시이트 (38)은 2개의 종방향 가장자리 (38C) 및 2개의 말단 가장자리 (38D)를 갖는다. (유사한 참조번호 시스템을 생리대의 다른 구성요소에 적용한다. 즉, 착용자의 신체에 대향하는 구성요소의 측면은 그 구성요소의 참조번호와 참조문자 "A"로 표시할 수 있다. 착용자의 내의에 대향하는 측면은 그 구성요소의 참조번호와 문자 "B"로 표시할 수 있다. 측면과 말단 가장자리는 그 구성요소의 참조번호와 각각 문자 "C" 및 "D" 로 표시할 수 있다).
적합한 상면시이트 (38)은 직물 및 부직물, 천공 성형된 열가소성 필름, 천공된 플라스틱 필름, 하이드로-형성된 필름, 다공성 포옴, 망상 포옴, 망상 열가소성 필름 및 열가소성 스크림(scrim)을 포함하지만 이들로 제한되지 않는 광범위한 물질로부터 제조될 수도 있다. 적합한 직물 및 부직물은 천연섬유(예를들면, 나무 또는 면섬유), 합성 또는 개질된 천연섬유(예를들면, 중합체성 섬유, 예를 들면 폴리에스테르, 폴리프로필렌 및 폴리에틸렌 또는 폴리비닐알콜, 전분계 수지, 폴리우레탄, 셀룰로즈 에스테르, 나일론, 및 레이온 섬유) 또는 천연섬유와 합성섬유의 배합물을 포함할 수 있다. 상면시이트 (38)이 부직물 웹을 포함할 경우, 이러한 웹은 방사결합되거나, 카딩되거나, 습식-층형성되거나, 용융취입되거나, 하이드로인탱글되거나 이들의 조합에 의해서 형성될 수도 있다.
천공된 필름은 일반적으로 이들이 적절하게 천공될 경우, 액체 투과성이기 때문에 상면시이트 (38)로서 바람직하고, 액체가 역류하여 착용자의 피부를 재습윤시키는 경향을 감소시킨다. 적합한 천공된 필름은 1975년 12월 30일자로 톰슨(Thompson)에게 허여된 미합중국 특허 제 3,929,135 호; 1982년 4월 13일자로 뮬란(Mullane)에게 허여된 미합중국 특허 제 4,324,426 호; 1982년 8월 3일자로 레이들(Radel)등에게 허여된 미합중국 특허 제 4,342,314 호; 1984년 7월 31일자로 아르(Ahr)등에게 허여된 미합중국 특허 제 4,463,045 호; 및 1991년 4월 9일자로 베어드(Baird)에게 허여된 미합중국 특허 제 5,006,394 호중에 기술되어 있다.
상면시이트 (38)을, 상면시이트 물질을 주름형성(Pleating), 파형형성(corrugating) 또는 링 롤링과 같은 기계적 공정에 적용시킴으로써 상면시이트가 신장될 때 개방될 수 있는 절첩부를 상면시이트내에 제공함으로써 신장가능하도록 제조할 수 있다. 이러한 공정은 상기 기술된 다수의 상면시이트 물질상에 수행할 수 있다. 본 발명의 하나의 바람직한 양태에서, 상면시이트 (38)은 미합중국 특허 제 4,463,045 호에 따라 제조하고 링 롤링시켜 종방향 신장성을 제공한다. 이러한 상면시이트는 1992년 8월 25일자로 존 제이. 커로(John J. Curro)등에 의해서 출원된, "Polymeric Web Having Deformed Sections Which Provide A Substantially Increased Elasticity To The Web"이란 제목의 미합중국 특허원 제 07/936,195 호중에 기술되어 있다.
링 롤링 또는 "예비 파형형성"을 위한 적합한 공정은 1978년 8월 15일자로 시슨(Sisson)에게 허여된 미합중국 특허 제 4,107,364 호; 1989년 5월 30일자로 사비(Sabee)에게 허여된 미합중국 특허 제 4,834,741 호; 1991년 2월 28일자로 제랄드 엠. 웨버(Gerald M. Weber)등에 의해서 출원되고 계류중인, 통상양도된 미합중국 특허원 제 07/662,536 호; 1991년 2월 28일자로 켄네쓰 비. 뷰엘(Kenneth B. Buell)등에 의해서 출원된 미합중국 특허원 제 07/662,537 호; 및 1991년 2월 28일자로 제랄드 엠. 웨버 등에 의해서 출원된 미합중국 특허원 제 07/662,543 호중에 기술되어 있다.
링 롤링된 상면시이트의 파형중에 위치하는 절첩선은 상면시이트가 종방향으로 신장가능하도록 횡방향으로 뻗어있다. 다른 실시양태에서, 절첩선은 종방향, 2가지 방향 및/또는 다른 방향으로 뻗을 수도 있다. 상면시이트 (38)은 절첩선에 수직 방향으로 신장가능하다.
바람직한 실시 양태에서, 상면시이트 (38)은 액체가 상면시이트 (38)을 통해서 더욱 신속하게 이동할 수 있도록 친수성을 갖는다. 이는 신체 분비물이 흡수 코어에 의해서 흡수되기 보다는 상면시이트로부터 유출될 가능성을 감소시킨다. 상면시이트는 계면활성제로 처리함으로써 친수성화 시킬 수 있다. 계면활성제를 적용시키기 위한 적합한 방법은 오스본에게 허여된 미합중국 특허 제 4,950,254 호 및 제 5,009,653 호중에 기술되어 있다.
또한 바람직한 실시 양태에서, 상면시이트 (38)의 내부면 (38B)는 그아래에 위치하는 흡수층과 접촉된 상태로 고정된다. 이러한 접촉 관계로 인하여, 상면시이트 (38)가 흡수 구성요소와 접촉하지 않을 경우 보다 액체가 상면시이트 (38)을 더욱 신속하게 투과한다. 상면시이트 (38)은 그아래의 층과 접착됨으로써 그아래의 층과 접촉된 상태로 유지된다. 그러나, 상면시이트 (38)의 표면을 그아래의 층의 표면과 반드시 접착시킬 필요는 없다. 접착제를 상면시이트와 그아래의 구성요소 사이에 적용시키거나, 그아래의 층의 섬유를 상면시이트와 함께 인탱글시키거나, 다수의 개별적인 융합접착에 의해서 상면시이트 (38)을 그아래의 흡수층에 융합시키거나, 또는 관련기술분야에 공지된 임의의 수단에 의해서 상면시이트 (38)을 그아래의 흡수 구성요소와 접촉된 상태로 유지시킬 수 있다.
흡수코어 (42)는 상면시이트 (38)과 배면시이트 (40)사이에 위치한다. 흡수코어 (42)는 생리혈 및 다른 신체 분비물을 흡수하기 위한 수단을 제공한다. 흡수코어 (42)는 흡수될 것으로 예측되는 유체의 총량보다 훨씬 큰 흡수용량을 가질 필요는 없다. 흡수코어 (42)는 일반적으로 압축가능하고, 유연하고, 착용자의 피부에 자극을 주지 않는다.
흡수코어 (42)는 이러한 목적을 위해 관현기술분야에 사용된 임의의 물질을 포함할 수 있다. 이러한 물질의 비제한적인 예는 일반적으로 에어펠트라고 불리는 분쇄된 나무 펄프와 같은 천연 물질, 크레이프된 셀룰로즈 웨딩(wadding), 하이드로겔-형성 중합체성 겔화제, (1993턴 6월 8일자로 영(Young)등에게 허여된 미합중국 특허 제 5,217,445 호중에 기술된 바와 같은) 개질된 가교결합된 셀룰로즈 섬유, 모세관 섬유(즉, 1993년 4꿜 6일자로 톰슨등에게 허여된 미합중국 특허 제 5,200,248 호중에 기술된 바와 같은 내부-섬유 모세관을 갖는 섬유), 흡수성 포옴, 흡수성 스폰지, 합성 스테이플 섬유, 중합체성 섬유, 피이트 모스(peat moss) 또는 이러한 물질에 상응하는 물질 또는 이러한 물질의 배합물을 포함한다.
상기 기술된 중합체성 겔화제는 또한 "흡수성 겔화물질" 또는 "초흡수성 물질"이라고도 불린다. 중합체성 겔화제는 물 또는 다른 신체 분비물과 같은 액체와 접촉시 이러한 액체를 흡수하여 하이드로겔을 형성하는 물질이다. 이러한 방법에서, 흡수코어 (42)중으로 배출된 액체는 중합체성 겔화제에 의해서 포획되고 함유됨으로써 본 발명의 제품에 개선된 흡수용량 및/또는 개선된 액체 보유 성능을 제공한다. 흡수 코어 (42)중에 사용되는 중합체성 겔화제는 일반적으로 실질적으로 수불용성이고, 약간 가교결합되고, 부분적으로 중화된 하이드로겔-형성 중합체 물질의 입자 (41)을 포함한다. 이러한 중합체성 겔화제는 펠렛, 플레이크 또는 섬유를 포함하는 다양한 형태를 가질 수 있다.
제 2 도중에 나타낸 하나의 바람직한 실시 양태에서, 흡수코어 (42)는 적층체이다. 이러한 적층체은 2개의 공기-층형성된 티슈, 즉, 제 1 및 제 2 티슈층(또는 "상부" 및 "하부" 티슈층) (43) 및 (47)사이에 위치한, 입자 (41) 형태의 초흡수성 중합체 물질의 층 (41)을 포함한다. 제 1 티슈층 (43) 및 제 2 티슈층 (47)은 초흡수성 중합체 물질을 함유하고, 흡수코어 (42)를 통해 흡수된 분비물의 측방향 흡상을 개선시키고, 흡수성을 제공한다. 이러한 티슈층 (43) 및 (47)은 2개의 분리된, 같은 (또는 다른) 티슈 시이트사이에서 초흡수성 물질 입자 (41)과 함께 절첩된 단일 티슈 웹을 포함할 수 있다.
미합중국 아이오와 무스카틴(Iowa, Muscatine) 소재의 그레인 프로세싱 코포레이션(Grain Processing Corporation)사로부터 상표명 "WATER-LOCK L-535"로서 구입할 수 있는 초흡수성 적층체이 적합한 적층체이다. 이러한 초흡수성 적층체은 1984년 8월 21일자로 페더슨(Pedersen)등에게 허여된 미합중국 특허 제 4,467,012 호; 1981년 4월 7일자로 린드세이(Lindsay)등에게 허여된 미합중국 특허 제 4,260,443호; 및 1986년 3월 25일자로 크레이머(Kramer)등에게 허여된 미합중국 특허 제 4,578,068 호중에 기술되어 있다. 적층된 흡수코어 (42)는 이를 절단하거나 슬리팅(slitting)시킴으로써 신장가능하도록 제조할 수 있다. 제 1 도는 흡수코어 (42)가 종방향으로 신장되도록 (바람직하게는 전체 영역에 걸쳐서) 슬리팅된 적층체임을 보여준다.
또다른 실시양태에서, 적층된 흡수코어 (42)는 20 내지 200% 의 신장성을 갖는(즉, 신장되지 않은 크기의 약 1.2 내지 3배로 신장될 수 있는) 티슈지로부터 제조함으로서 신장가능하도록 제조할 수 있다. 이러한 티슈시이트는 다수의 방법에 의해서 제조할 수 있다. 이러한 티슈지는 하나의 실시양태에서, 통상적으로 크레이프된 티슈이다. 예를들면, 이러한 티슈지는 양키(Yankee) 건조기로부터 크레이프된 직후 이러한 크레이프가 티슈로부터 제거되기전에 얻은 "바운티(BOUNTY)" 티슈일 수도 있다. 이러한 티슈를 제조하기 위한 방법은 1992년 3월 24일자로 스무코스키(Smurkoski)등에게 허여된 미합중국 특허 제 5,098,522 호중에 기술되어 있다.
생리대 (20)의 종방향 및 말단 가장자리 (22) 및 (24)는 신장될 경우, 바람직하게는 생리대로부터 액체 또는 액체-함유 초흡수성 물질이 흡상되거나 배출되는 것을 방지하기 위해서 밀봉된다. 또다르게는, 생리대 전체의 가장자리를 밀봉시키기보다 흡수코어 (42)의 가장자리 (42C)와 (42D)를 밀봉시킬 수도 있다. 흡수코어 (42)의 가장자리는, 예를들면, 티슈층에 의해서 감싸지거나 덮혀진다. 또다른 실시 양태에서, 티슈의 가장자리는 절첩되거나, 그렇지 않으면 흡수코어 (42)로부터 액체 또는 액체-함유 초흡수성 물질 입자가 흡상되거나 배출되는 것을 방지하기 위해서 조절될 수도 있다. 생리대의 둘레를 따라 형성된 모든 밀봉부는 잡아늘려도 파괴되지 않아야 한다(즉, 생리대의 사용시간동안 밀봉부가 유지되어야 한다).
배면시이트 (40)은 흡수코어 (42)중에 흡수되고 함유된 배설물이 팬티, 파자마 및 내의와 같은, 생리대와 접촉하는 제품을 습윤시키는 것을 방지한다. 이러한 배면시이트 (40)은 액체(예를들면, 생리혈 및/또는 뇨) 불투과성이다. 배면시이트 (40)은 바람직하게는 얇은 가요성의 액체 불투과성 물질이다.
배면시이트 (40)은 직물 또는 부직물, 폴리에틸렌 또는 폴리프로필렌의 열가소성 필름과 같은 중합체성 필름, 또는 필름-피복된 부직물과 같은 복합물을 포함할 수도 있다. 바람직하게는, 배면시이트 (40)은 약 0.012 mm(0.5 mil) 내지 약 0.051 mm(2.0 mil)의 두께를 갖는 폴리에틸렌 필름이다. 대표적인 폴리에틸렌 필름의 예는 미합중국 오하이오 신시네티 (Ohio, Cincinnati) 소재의 클로페이 코포레이견(Clopay Corporation)사로부터 상표명 P18-0401로 시판되거나, 미합중국 인디아나 테레 호트(Indiana, Terre Haute) 소재의 트레드가 필름 프로덕츠(Tredegar Film Products)사로부터 상표명 XP-39385로서 시판되는 것이다.
배면시이트 (40)은 바람직하게는 엠보싱되고/되거나 매트 처리되어 더욱 천과 유사한 외형을 갖는다. 또한, 배면시이트 (40)은 증기는 흡수코어 (42)로부터 배출시키지만(즉, 배면시이트 (40)은 통기성이다), 배설물은 통과시키지 않는다. 예를들면, 본원에 기술된 팬티 라이너와 같이, 물로 씻어내릴 수 있거나 생분해가능한 배면시이트를 사용할 수도 있다.
배면시이트 (40) 물질을 주름형성, 파형형성 또는 링 롤링시키는 것과 같은 기계적 조작시킴으로써 배면시이트에 신장성을 부여할 수 있다. 그러나, 바람직하게는, 이러한 배면시이트 (40)은 1984년 10월 9일자로 누크(Wnuk)에게 허여된 미합중국 특허 제 4,476,180 호중에 기술된 필름과 같은 탄성중합체성 필름으로부터 형성시켜 신장성을 부여할 수도 있다. 이러한 필름은 미합중국 일리노이 레이크 쭈리히(IL, Lake Zurich) 소재의 엑손 케미칼 캄파니(Exxon Chemical Company)로부터 상표명 엑손 필름 EXX-500(공식명칭 EXX-7)으로서 구입할 수 있다.
또다른 특히 바람직한 신장성 배면시이트 (40)은 미합중국 위스콘신 와우와토사(Wisconsin, Wauwatosa) 소재의 핀들리 어드히시브스 캄파니(Findley Adhesives Company)사에 의해 제조된 신장성 접착 필름 #198-338이다. 이러한 핀들리 접착성 필름은 200 내지 300%로 신장될 수 있는 액체 불투과성 필름이다. 이러한 핀들리 접착성 필름은 탄성적으로 신장될 수 있기 때문에 바람직하다. 배면시이트 (40)은 2개이상의 층을 포함하는 신장가능한 적층 구조물을 포함할 수도 있다. 예를들면, 배면시이트 (40)은 신장성 부직물 웹 또는 신장성 필름에 의해 양쪽 측면이 덮혀진 핀들리 어드히시브 필름의 층으로 형성된 적층체을 포함할 수 있다. 또다른 적합한 배면시이트 물질은 1991년 4월 16일자로 오스본에게 허여된 미합중국 특허 제 5,007,906호중에 기술된 부직물/필름 적층체이다.
생리대 (20)에는 또한 상면시이트 (38)과 흡수코어 (42)사이에 위치한 선택적이고 보다 덜 신장가능한 요소 (216)이 제공된다. 이러한 보다 덜 신장가능한 요소 (216)은 생리대 (20)의 거의 중심부 (32)중에 위치한다. 보다 덜 신장가능한 요소 (216)은 생리대의 나머지 부분이 신장되는데 대해 굴곡된다(바람직하게는 들어올려져서 신체접촉을 개선시킨다).
보다 덜 신장가능한 요소 (216)은 일반적으로 생리대 (20)의 주본체부 (21)의 적어도 몇가지 다른 부분보다 덜 신장가능한 임의의 유형의 구성요소일 수 있다. (생리대의 이러한 다른 부분이란 보다 덜 신장가능한 차단부가 아닌 생리대의 부분이다. 이러한 차단부는 바람직하게는 상기 보다 덜 신장가능한 요소에 대해 독립적으로 작용한다.) 이러한 보다 덜 신장가능한 요소 (216)은 비교적 신장불가능할 수도 있다. 다른 실시양태에서, 보다 덜 신장가능한 요소는 약간의 신장성을 가질 수도 있다.
보다 덜 신장가능한 요소 (216)은 신체-대향면 (216A), 가멘트-대향면 (216B), 한쌍의 종방향 가장자리 (216C) 및 한쌍의 말단 가장자리 (216D)를 갖는다. 보다 덜 신장가능한 요소 (216)의 구조는 바람직하게는 안쪽으로 작용하는 측방향 압축력이 보다 덜 신장가능한 요소의 종방향 가장자리 (216C)에 적용될 경우 발생하는 휨 또는 비틀려지기에 충분히 단단하다. 보다 덜 신장가능한 요소 (216)은 바람직하게는 사용시 생리대 (20)상에 적용되는 측방향 압축력에 대해 z-방향으로 들어올려지지 않고 안쪽으로 접혀지지 않아야 한다(즉, 스폰지와 같이 찌그러지지 않아야한다). 보다 덜 신장가능한 요소 (216)은 물질의 층형태, 또는 몇가지 다른 적합한 형태를 가질 수 있다. 보다 덜 신장가능한 요소 (216)은 바람직하게는 건조시와 (신체 분비물에 의한) 습윤시 모두 충분한 강성을 유지한다.
덜 신장가능한 요소 (216)를 임의의 적합한 물질로부터 제조할 수 있다. 상기 물질은 부드럽고, 유연하며, 흡수성이 있어야 하지만, 구부러지거나 비틀려지기에 충분히 단단해야 한다. 덜 신장가능한 요소 (216)를 본원에서 구체화한 많은 기본 형태의 흡수 코어 물질로부터 제조할 수 있다. 그러나, 이들 코어 물질을, 바람직하게는 신장성을 제공하기 위해 임의의 처리(링 롤링, 주름형성, 파형 형성 또는 슬리팅)를 해서는 안된다. 제 1 내지 3 도는 덜 신장가능한 요소 (216)가 갈라지지 않은 초흡수성 적층체을 포함하는 양태를 나타낸다. 또한, 바람직하게는, 덜 신장가능한 요소 (216)는 중앙의 종방향으로 배열된 절첩선을 만들도록 절첩시킴으로써 버클링(buckling)을 제공하도록 고안되어 있다.
덜 신장가능한 요소 (216)는 단순히 코어 (42)의 상부에 둘 수 있고, 생리대 (20)의 주변 구성요소에 대해 달라붙게 맞추므로써 적절하게 고정시킬 수 있다. 제 1 내지 3 도에 나타낸 양태에서, 덜 신장가능한 요소 (216)는 각각 그의 종방향 측면 가장자리에 단일점 (230)에 고정되어 있다.
생리대 (20)가 신장되는 경우,생리대의 중심 영역 (32)이 좁아진다. 이는 덜 신장가능한 요소 (216)가 굽어지거나 비틀려지게 하고, 생리대 (20)의 종방향 중심선 L을 따라서 융기 (218)(제 4 및 5 도에 도시됨)를 형성한다.
제 1 내지 5 도에 나타낸 차단부 (44)는 상면시이트 (38)를 덮는 물질의 좁은 스트립을 포함한다. 차단부 (44)는, 바람직하게는, 적어도 생리대의 종방향 측면 가장자리 (22)를 따라서 배치된다. 스트립 (44)은 각각 외부를 향한 측면 (44A), 내부를 향한 측면 (44B), 내부 가장자리 (44C') 및 외부 가장자리 (44C")를 포함하는 한쌍의 가장자리, 및 한쌍의 말단 (44D)를 갖고 있다. 외부 가장자리 (44C")는 내부 가장자리 (44C')보다 생리대의 종방향 및 횡방향 증심선의 교차점에서 보다 멀리 배치된다.
스트립의 외부 가장자리 (44C") 및 말단 (44D)을 생리대의 둘레 (26)을 따라 상면시이트 (38)에 고정시킴으로써, 차단부의 근위(proximal) 가장자리를 형성한다. 스트립의 내부 가장자리 (44C')를 스트립의 말단 (44D) 사이의 상면시이트에서 떼어내 차단부 자유 원위 (free distal) 가장자리를 형성한다. 제 1 도 및 2 도는 상면시이트 (38)에 차단부 (44)를 결합시키는 바람직한 방법을 나타낸다. 이 양태는 생리대의 가장자리 (22) 및 (24)와 동일한 평면 모형 구조를 갖는 외부 가장자리 (44C")를 가진 차단부 (44)를 갖고 있다. 외부 가장자리 (44C")는 이들 측면 가장자리와 직접 접촉해 있다. 내부 가장자리 (44C')는 흡수 코어를 약간 지나 안쪽으로 신장한다.
바람직하게는, 액체 불투과적인 차단부 밀봉부 (92)에 의해 차단부 (44)를 상면시이트 (38)에 결합한다. 차단부 밀봉부 (92)은 본원에서 기재된 임의의 적합한 형태의 접착수단일 수 있다. 바람직하게는, 차단부 밀봉부 (92)은 상면시이트 및 배면시이트 (하기에 기재된다)를 붙이는데 사용된 주변 접합선(seam) (90)와 거의 동일한 구조로 도포된 접착제 또는 열밀봉을 포함한다.
제 1 및 2 도에 나타낸 차단부 (44)는 단지 하나의 바람직한 구조를 갖는다. 차단부의 크기 및 형태 및 차단부를 생리대에 결합시키는 방법은 다양하게 변경시킬 수 있다. 예를들면, 차단부는 기저귀와 같은 다른 형태의 흡수 제품에서와 같이 다른 양태에서 크기가 훨씬 클수 있다. 차단부는 흡수 제품의 가장자리와 같은 구조일 필요도 없고, 흡수 제품의 가장자리와 많이 접촉될 필요도 없다. 예를들면, 차단부를 흡수 제품의 가장자리로부터 안쪽으로 이격된 근위 가장자리에서 결합될 수 있다. 또한, 덜 바람직하게는, 차단부는 차단부의 말단 사이의 특정 지점에서 생리대에 결합되는 원위 가장자리를 가질 수 있다. 다른 양태도 가능하다.
차단부 (44)는 임의의 적합한 액체 불투과성이거나 또는 액체 내성 물질을 포함할 수 있다. 차단부는 동일하게 적용된 힘으로 접착된 구성요소 (예를 들면 상면시이트 (38))보다 덜 신장가능하다. 차단부는 비교적 신장가능하지 않을 수 있다. 또다르게는, 차단부는 신장가능하지만 이들이 접착되어 있는 구성요소보다 덜 신장가능하다.
제 1 내지 3 도에 나타낸 바람직한 양태에서, 차단부는 신장가능한, 바람직하게는 탄성적으로 신장가능한 필름, 예를들면 1991년 4월 16일자로 누크 (Wnuk)에게 허여된 미합중국 특허 제 4,476,180 호에 따라서 제조된 필름을 포함한다. 상기와 같은 필름은 일리노이 레이크 쭈리히 소재의 엑손 케미칼 캄파니에서 입수된 탄성중합체성 필름 EXX-500 (EXX-7)이다. 특히 바람직한 양태에서, 차단부 (44)는 부드러운 몸체-대향 표면을 갖는 상기와 같은 필름 (144)의 스트립을 포함하여, 착용자에게 안락함을 증가시킨다. 제 2 도는 필름 (144)의 스트립이, 외부-대향 측면에 적층된 부드럽고, 바람직하게는 소수성이 큰 부직 물질 (146)층을 갖는 예를 보여준다.
특히 바람직한 양태에서, 유사한 스트립은 생리대의 말단 가장자리를 따라 고정되어 생리대의 전체 둘레를 따라 차단부를 형성할 수 있다. 측면 및 말단 가장자리에 따라 위치된 스트립은 서로 접착되어 전체 둘레에 연속 차단부를 제공할 수 있거나, 또는 접착되지 않을 수 있다.
차단부는 하기 방법으로 작동한다. 생리대가 연신되지 않는 경우, 스트립 (44)은 상면시이트 (38)에 대해 편평하게 놓인다. 생리대가 연신되는 경우, 스트립 (44)의 접착되지 않은 부분이 편평한 위치에서 보다 직립된 위치로 변화되고, 생리대의 종방향 가장자리를 따라 내부를 향한 입술모양 (또는 개스킷형)을 형성하여 상면시이트를 지나는 액체의 유동을 차단하는 차단부로서 작용한다. 스트립의 융기는 신장된 차단부 스트립의 접착된 가장자리와 접착되지 않은 가장자리의 양이 다르기 때문이다. 바람직하게는, 제 5 도에서와 같이, 생리대의 차단부 및 가장자리 모두는 롤링되어 입술모양을 형성하고 생리대 가장자리를 따라 "U"자형 차단부 구조를 제공한다.
생리대 (20)가 연장될 수 있도록 하는 임의의 적합한 방식으로 전술한 생리대의 구성요소(상면시이트, 배면시이트 및 흡수코어 등)을 함께 고정시킬 수 있다. 제 1 도에 도시된 바람직한 실시양태에서는, 상면시이트 (38) 및 배면시이트 (40)의 가장자리가 흡수코어 (42)의 가장자리를 지나 바깥쪽으로 연장되도록, 생리대 (20) 구성요소의 크기를 정한다. 코어 (42)의 가장자리를 지나 바깥쪽으로 연장되는 상면시이트 (38)의 가장자리 부분을 배면시이트 (40)의 상응하는 부분에 고정시킨다. 제 1 도에 도시된 바와 같이, 액체 불투과성 접합선 (90)를 따라 상면시이트 (38)를 배면시이트 (40)에 바람직하게 고정시킨다. 이러한 목적을 위해 당해 분야에서 통상적으로 이용하는 임의의 수단에 의해, 바람직하게는 배면시이트의 접착제에 상면시이트 (38)를 접착시킴으로써 접합선 (90)를 만들 수 있다.
이러한 구조에서는 인접한 구성요소의 표면이 서로 고정되지 않아도 생리대의 구성요소가 적절하게 고정됨을 발견하였다. 그러나, 전술한 바와 같이 때로는 구성요소중 일부를 표면에서 고정시키는 것이 바람직하다.
전술한 것은 구성의 용이성 면에서 바람직한 실시양태이다. (다양한 구성요소를 단위체로 만드는 다른 수단을 이용할 수 있다.) 예컨대, 본 발명은 또한 소위 "튜브" 제품을 포함한다. 이들 제품에서는, 흡수코어 및 배면시이트 둘레를 액체 투과성 커버 물질(예컨대 상면시이트 물질)로 완전히 감쌀 수 있으며, 이어 구성요소를 함께 고정시킬 수 있다. 다른 구조에서는, 상면시이트로 코어 둘레를 감싸고 감싸여진 코어를 배면시이트에 놓은 후 고정시킬 수 있다.
제 3 도는 생리대 (20)를 팬티의 가랑이에 고정시키기 위하여 감압성 접착제 (50) 같은 패스너를 생리대의 의복 표면 (20B)에 제공할 수 있음을 도시하고 있다. 다른 적합한 형태로 접착제를 도포할 수 있다. 접착 패스너 (50)는 신장성, 비신장성일 수 있거나, 또는 이를 패턴의 일부는 신장성이고 일부는 비신장성이도록 도포할 수도 있다.
접착제가 신장성인 경우에는, 표 1에 기재된 바와 같이 생리대와 거의 동일한 정도로 신장되는 것이 바람직하다. 적합한 신장성 접착제는 신장성 접착제 자체 및 신장성 접착제와 차단 필름의 조합체를 포함한다. 당해 분야에 공지되어 있는 임의의 신장성 접착제를 사용할 수 있다. 적합한 신장성 접착제/차단 필름 조합체는 신장성 차단 필름 재료상에 사용되는 비신장성 접착제; 핀들리(Findley) 접착제 198-338 같은 신축적으로 연신가능한 접착 필름; 또는 저 모듈러스 탄성 필름상의 분무 접착제(예컨대 3M 접착제 1442)를 포함하지만 이들로 한정되지는 않는다.
적합한 비신장성 접착제는 센츄리 어드헤시브(Century Adhesive)에서(상품번호 A3O5-4), 또는 오하이오 코빙톤 소재의 앵커 콘티넨탈, 인코포레이티드(Anchor Continental, Inc.), 3 시그마 디비젼(3 Sigma Division)에서 구입할 수 있는 0.6밀 패스(pass) 및 에이취 비. 풀러 캄파니(H. B. Fuller Co.)에서 제조한 풀러 H-2238ZP로서 기술된 접착제일 수 있다. 적합한 비신장성 접착 패스너는 미합중국 특허 제 4,917,697호에 더욱 상세하게 기재되어 있다.
접착 패스너 (50) 위에는 릴리이스 라이너(또는 커버 스트립) (52)가 덮여있는 것이 바람직하다. 시판되는 임의의 릴리이스 라이너를 사용할 수 있다. 한가지 바람직한 실시양태에서는, 낱개로 포장되는 생리대 및 사용 후 생리대를 폐기시킬 수 있는 용기를 동시에 제공하는 포장지로 릴리이스 라이너를 대신할 수 있으며, 이러한 포장지는 1985년 12월 3일자로 스완슨(Swanson) 등에게 허여된 미합중국 특허 제 4,556,146호에 기재되어 있다.
표현을 간결하게 하기 위하여 처음에는 패스너를 접착제라고 기재하였다. 그러나, 패스너의 형태는 접착제로 한정되지 않는다. 바람직한 패스너는 감압성 접착제, 기계적 패스너 및 접착제와 기계적 패스너의 조합체 같은 접착 고정 수단을 포함하지만 이들로 한정되지는 않는다. 또한 생리대에 임의적인 폴리에틸렌 말단 가드(140)를 제공할 수 있다.
하기 실시예는 본 발명의 실시에 대해 더욱 상세하게 설명한다. 그러나, 하기 실시예는 본 발명을 본원에 기재된 흡수제품으로만 제한하지는 않는다.
