Definitions

  • FIG Z FIG. 4
  • This invention relates to a novel sanitary napkin which is capable of automatically adapting itself to conform to the body of the person using it.
  • Conventional sanitary napkins consist of a mass of absorbent material such, for example, as cotton fibers or cellulose pulp, in the form of a parallelopiped about cm thick.
  • This absorbent napkin has, because of its structure, definite dimensions which cannot be modified except by substantially compressing the materials forming the absorbent material.
  • the present invention is directed to the new article of manufacture which consists of a sanitary napkin made of absorbent material which is characterized by the fact that it comprises a plurality of balls of absorbent material which are movable with respect to each other, so that they may be displaced to change the shape of the article, said balls being preferably contained within a deformable bag which is itself made of an absorbent material.
  • the bag containing the absorbent balls is itself encircled by a layer of absorbent material, for example a layer of cotton fibers.
  • the absorbent mass formed in this manner may also be placed in a net in a conventional manner.
  • the balls may be made from all sorts of absorbent material. They may, for example, comprise wood fibers or viscose fibers, cellulose wadding or cotton wadding.
  • the balls have a substantially uniform diameter, so as to improve their mobility within the bag which contains them, and to permit the napkin to adapt itself to the body of the person using it.
  • the balls may have a diameter of the order of 3 to 4 mm.
  • balls when speaking of balls in the present description, it is not intended to refer exclusively to masses having a perfectly spherical surface, but only to masses of fibers having a rounded aspect.
  • the balls may thus be generally cylindrical.
  • These balls of absorbent material be adapted to change position easily with respect to each other so as to permit the napkin to automatically conform to the contours of the body.
  • all the absorbent material may be placed inside a bag made of a flexible material, which is itself absorbent, or which is permeable to the liquid which must be absorbed by the balls.
  • the balls may thus be placed inside a bag of woven or knitted fabric or a non-woven web.
  • the balls may be positioned inside a bag of fine mesh net material.
  • the nature of the material of which the bag containing the balls is made is not very important, except to the extent that this material must permit a change in the shape of the mass of balls and the passage of liquid which is to be absorbed by the balls.
  • FIG. I is a perspective view of a napkin according to the invention, showing one end cut off;
  • FIG. 2 is a longitudinal section through the sanitary napkin shown in FIG. 1;
  • FIGS. 3 and 4 are transverse cross-sections showing two different possible shapes for the napkins of FIGS. 1 and 2.
  • FIGS. 1 and 2 show in a schematic :manner a napkin one end of which has been cut off.
  • FIGS. 1 and 2 show a bag 1 containing balls 2 of absorbent material.
  • This bag is made for example of woven cotton cloth or of a non-woven web of cotton or some other suitable material. It may also be made in the form of a net having meshes sufficiently fine to prevent the balls 2 contained therein from falling out.
  • the balls may be made, for example, of wood fibers. They have, in a particular embodiment of the invention, diameters of from 3 to 6 mm.
  • the quantity of balls inside the bag 1 is such that theballs are not compressed inside the bag and have a certain mobility with respect to each other.
  • the bag 1 containing the balls 2 is surrounded by a sheet 3 of absorbent material, for example, a sheet of cotton fibers.
  • the absorbent sheet 3 has been shown with its ends 3a bent slightlyinward at the end In of the bag. This configuration is not essential, and it is possible to terminate the sheet 3 substantially in alignment with the end In of the bag which contains the balls.
  • a napkin made in this manner has a certain capacity for deformation due to the fact that its center consists of the balls 2 which may easily be displaced with respect to each other.
  • FIGS. 3 and 4 show the bag 1, the balls 2, and the absorbent sheet 3.
  • the napkins according to the invention have the characteristic of having a transverse section of an indeterminate shape, the width and thickness of which may be varied to adapt it automatically to the needs of the user.
  • the napkins according to the invention have excellent absorptive and comfort qualities regardless of the shape of the body of the user.
  • Sanitary napkin comprising a plurality of rounded balls of absorbent material enclosed in a textile bag, said balls having a diameter so small that they form several layers in all directions and are movable with respect to each other inside said bag so that the shape of the napkin may conform to the configuration of the body of the user.
  • Napkin as claimed in claim 2 in which the deformable bag is made of a net having meshes sufficiently small to prevent the passage of said balls therethrough.
  • Napkin as claimed in claim 1 in which the balls are made of a material selected from the group consisting of wood fibers, viscose fibers, cellulose wadding and cotton wadding.
