Definitions

  • two portions should be considered to be overlapping when they, at least partially, lie one on top of the other when the component layer is laid flat.
  • the overlapping portions may be in complete contact with one another, in partial contact, or generally in a spaced apart relationship. No particular state in this respect is required nor is essential, neither when the article is laid flat nor when it is in use.
  • a third embodiment of the invention would encompass the simple placement of additional material on the cover layer to form a "sleeve-like" overlapping portion and act as a hindrance to fluid flow.
  • this material could be sealed to the cover layer in various configurations to form a "pocket-like” structure to entrap the fluid in addition to acting as a simple hindrance.
  • Figure 2 is a top plan view of the article (body- facing face) of Figure 1;
  • Figure 3 is a cross-sectional view of the article along the line 3—3 in Figure 2;
  • Figure 4 is a cross-sectional view of a second embodiment similar to that of Figure
  • a fluid transfer layer 46 adjacent to the cover layer 40 on its inner side and bonded to the cover layer 40 is a fluid transfer layer 46 that may form part of the absorbent system.
  • the transfer layer 46 provides the means of receiving body fluid from the cover layer 40 and holding it until the highly-dense absorbent layer 42 has an opportunity to absorb the fluid.
  • a barrier layer 44 comprising liquid-impervious film material so as to prevent liquid that is entrapped in the absorbent layer 42 from egressing the sanitary napkin and staining the wearer's undergarment.
  • the barrier layer 44 is made of polymeric film, such as polyethylene which is both inexpensive and readily available.
  • the polyethylene is capable of fully blocking the passage of liquid or gas that may emanate from the absorbent system.
  • breathable films may be used that allow passage of gases while blocking liquid.
  • the napkin may be provided with adhesives 48, such as hot-melt adhesives capable of establishing a temporary bond with the undergarment material.
  • adhesives 48 may be applied to the bottom (garment-facing face) of the barrier layer 44 in various patterns, including complete adhesive coverage, parallel longitudinal lines, a line of adhesive following the perimeter of the structure, transverse lines of adhesive or the like.
  • the sanitary napkin of this invention may be attached to a belt that encircles the waist of the wearer.

Abstract

L'invention concerne une couche de composant se prêtant à une utilisation dans un article hygiénique absorbant, la couche de composant comprend a) une première partie sensiblement plane et b) un second partie sensiblement plane recouvrant ladite première partie. Lesdites parties superposées forment un obstacle vertical à l'écoulement d'un fluide à travers la couche de composant.
