Abstract
An absorbent article that provides leakage protection and/or skin protection, as well as methods for using and preparing the absorbent article and novel compositions and composites for use in the absorbent article, is disclosed. The absorbent article comprises a permeable topsheet; a substantially impermeable backsheet; an absorbent core positioned between said permeable topsheet and said substantially impermeable backsheet; and a hydrophobic composition selectively disposed on the absorbent article to contain leakage. The hydrophobic composition is disposed at one or more leak protection zones.
Claims74
An absorbent article comprising:
- a permeable topsheet;
- a substantially impermeable backsheet;
- an absorbent core positioned between said permeable topsheet and said substantially impermeable backsheet;
- and
- a hydrophobic composition disposed between the skin-opposing surface of the substantially impermeable backsheet and the skin of a wearer of the absorbent article at a first leak protection zone and a second leak protection zone, said first leak protection zone being located on the topsheet adjacent to and inward of the front edge of the absorbent article and positioned centrally between the two inner leg gathers, and said second leak protection zone being located near the back edge of the absorbent article and positioned centrally between the two inner leg gathers.
2 more elements
An absorbent article comprising:
- a permeable topsheet
- a substantially impermeable backsheet;
- an absorbent core positioned between said permeable topsheet and said substantially impermeable backsheet;
- and
- a hydrophobic composition disposed between the skin-opposing surface of the substantially impermeable backsheet and the skin of a wearer of the absorbent article at a first leak protection zone and a second leak protection zone, said first leak protection zone being located on the topsheet adjacent to and inward of the front edge of the absorbent article and positioned centrally between the two inner leg gathers, and said second leak protection zone being located near the back edge of the absorbent article and positioned centrally between the two inner leg gathers;
- wherein said hydrophobic composition comprises a substance effective for skin protection, a substance effective for skin care, a substance effective for skin wellness, a substance effective for skin improvement, a substance perceived as having skin wellness benefits or combinations thereof.
3 more elements
An absorbent article comprising:
- a permeable topsheet;
- a substantially impermeable backsheet;
- an absorbent core disposed between the permeable topsheet and the substantial impermeable backsheet;
- and
- a tissue layer disposed between the absorbent core and the permeable topsheet;
- and
- a hydrophobic composition disposed on said tissue layer at a pair of leak protection zones extending longitudinally along the two opposing side edges of the tissue layer.
4 more elements
An absorbent garment comprising:
- a front and a rear waist portion cooperating to form a waist opening;
- a crotch region formed between said front waist portion and said rear waist portion;
- a pair of leg openings on opposed sides of the crotch region;
- a permeable topsheet, a substantially impermeable backsheet and an absorbent core positioned between said topsheet and said backsheet;
- a hydrophobic composition disposed between the skin-opposing surface of the substantially impermeable backsheet and the skin of a wearer of the absorbent article at a first leak protection zone and a second leak protection zone, said first leak protection zone being located on the topsheet adjacent to and inward of the front edge of the absorbent article and positioned centrally between the two inner leg gathers, and said second leak protection zone being located near the back edge of the absorbent article and positioned centrally between the two inner leg gathers.
2 more elements
A method for preparing an absorbent article comprising:
- disposing a hydrophobic composition on a topsheet adjacent to and inward of a front edge or back edge and positioned centrally and/or on a tissue layer longitudinally along the two opposing side edges of said tissue layer;
- and
- forming an absorbent article comprising the topsheet and/or tissue layer.
A method for preparing an absorbent article comprising:
- disposing a hydrophobic composition at predetermined areas on a tissue layer or permeable topsheet;
- forming said tissue layer or permeable topsheet into an absorbent core such that the predetermined areas correspond to a pair of leak protection zones extending longitudinally along the two opposing side edges of the tissue layer or to a pair of leak protection zones located on a topsheet adjacent to and inward of the front edge and/or back edge and positioned centrally.
A composition in an absorbent article for providing leak protection and improved skin wellness comprising:
- a hydrophobic substance selected from the group consisting of cocoa butter, petrolatum, dimethicone, a zinc oxide preparation, beeswax, lanolin, jojoba oil and combinations thereof;
- wherein said hydrophobic substance is effective in providing leak protection during use of the absorbent article when disposed at a pair of leak protection zones extending longitudinally along two opposing side edges of a tissue layer or at a pair of leak protection zones being located on a topsheet adjacent to and inward of a front edge and/or a back edge of the absorbent article and positioned centrally between two inner leg gathers.
