Definitions

  • Sanitary napkin comprises flexible absorbent mass sur- [56] References C'ted rounding core of compressed hydrophilic fibers.
  • This invention relates to a new sanitary napkin which has the property of retaining a very large quantity of absorbed liquid.
  • sanitary napkin which comprises a mass of absorbent material such, for example, as cotton fibers or cellulose pulp, which is substantially parallelopipedic in shape.
  • absorbent masses hold a large quantity of liquid slight recompression of the mass results in the liquid being squeezed out and this is a great disadvantage to the user of the napkin.
  • absorbent mass is compressed, its retentive properties are improved, but in this case, the material becomes too hard to be correctly positioned by the user and adapted to her individual anatomy.
  • sanitary napkin which is, on the one hand, sufficiently flexible to permit its adaptation to the anatomical differences between users without irritating the mucous membrances with which they come in contact and, on the other hand, has particularly valuable retentive properties.
  • a sanitary napkin essentially characterized by the fact that it comprises, in the first place, a flexible absorbent mass consisting of fibers or pulp and having preferably a substantially parallelopipedic shape, and, in the second place, a core consisting of compressed hydrophilic fibers, said core being surrounded on all sides by said absorbent mass and being preferably positioned in the center of said mass.
  • the absorbent mass consists of a layer of hydrophobic cotton, partially surrounding a mass of hydrophilic cotton, with the mass exposed in the area at which the liquid to be absorbed reaches the napkin.
  • the core of compressed hydrophilic fibers consists of fibers obtained from a ground wood pulp which is subsequently compressed, for example by means of a press or calender. The fibers forming the core are recompressed at a pressure between 900 and 1,200 bars.
  • the absorbent mass is formed into a layer which is folded around the compressed core.
  • the absorbent mass surrounding the compressed core is positioned inside a net of cotton fibers or polyamide threads.
  • the advantages are particularly substantial when there is heterogeneity between the fibers of the flexible absorbent mass and the compressed fibers of the core. It has been found that, if the sanitary napkin is supplied with a liquid to be absorbed at one point on the hydrophilic flexible absorbent mass, the core in alignment therewith sucks the liquid from the interior of the flexible absorbent fibrous mass, which liquid distributes itself inside the core, so long as core is not completely saturated. It has thus been found that the retentive properties of the entire core are utilized until it has become completely saturated before the retentive properties of the flexible absorbent mass which surrounds the core are fully utilized.
  • the hardness of the core formed by the compressed fibers presents no problem to the user because of the fact that this core is surrounded by a flexible absorbent mass so that it is never in contact with the mucous membranes of the user and causes no irritation.
  • FIG. 1 is a perspective view showing a sanitary napkin according to the invention.
  • FIG. 2 is a transverse cross-sectional view taken along the line ,IIll of FIG. 1.
  • reference numeral 1 indicates the net which encircles a, sanitary napkin of a substantially parallelopipedic shape.
  • the napkin is about 7 cm wide and 20 cm long.
  • Net 1 is made of cotton thread and weighs about 1.7 g.
  • the napkin comprises an outer layer of hydrophobic cotton 2 encircling a mass of hydrophilic cotton 3 in the center of which a compressed core 4 is located.
  • the hydrophobic cotton 2 surrounds the entire napkin except for the zone 5, which must be in contact with the mucous membranes of the user, said zone consisting of the hydrophilic cotton 3.
  • the hydrophobic cotton and the hydrophilic cotton constitute, considered together, a napkin which is folded about the core 4, with the two edges of the napkin coming into contact in the zone 5 of the sanitary napkin.
  • the layer 2 of hydrophobic cotton is a rose-colored carded layer, which, after conventional cottontreatment is rendered impermeable by spraying a product sold commercially as Aquaphobol thereon.
  • the weight of the layer 2 is 2 g.
  • the mass of hydrophilic cotton 3 forms a layer which is partly carded material and partly just unwadded.
  • the material is boiled in a bath containing, for each liter of aqueous solution, 25 grams of soda 5 grams of sodium carbonate, 5 grams of trisodium phosphate, 1 cm of a product sold under the trade mark CELANOL A.T.D., and 1.5 cm of a product sold commercially as CELON B. It is bleached with an aqueous solution containing,
  • the layer 3 of hydrophilic cotton weighs 6 g.
  • the material for the layer 4 is obtained by grinding a wood pulp, predominantly pine, with traces of fir.
  • the fibers have an average length of 1.33 mm and are about 86.3 alpha-cellulose by weight. After grinding, the fibers of this wood pulp are compressed by means of a press at 1,200 bars.
  • the weight of the core 4 is 4.30 g and its dimensions are about mm X 30 mm X 5 It has been found that the sanitary napkin which has just been described has surprising retentive properties because the liquid absorbed in the zone 5 by the hydro philic cotton 3 is sucked up by the core 4 and retained in this core until complete saturation of the core. It has also been found that, even if the liquid is supplied to a single area on the core, the liquid absorbed diffuses along the length of the core, so that local saturation does not lead to the release of the liquid into the inner layers of the hydrophilic cotton 3.
  • the sanitary napkin according to the invention has substantial absorbing properties because the absorption due to the presence of the core 4 is added to that due to the flexible absorbent mass constituted by the cotton.
  • the cotton layer 3 is interposed between the core 4 and the mucous membranes of the user prevents the sanitary napkin from causing any chafing other than that normally caused by such napkins.
  • Sanitary napkin for external use comprising an outer flexible absorbent mass and a core (4) consisting of compressed hydrophilic fibers, said core being positioned substantially in a central zone of said absorbent mass characterized by the fact that the absorbent mass consists of an internal mass (3) of hydrophilic cotton and an external layer (2) of hydrophobic cotton partially enclosing the internal mass, the outer layer surrounding the internal mass being interrupted in the zone in which menstrual liquid will reach the napkin in normal use.
  • Napkin as claimed in claim 1 in which the internal mass (3) of hydrophilic cotton is formed from a single folded layer having abutting edges (5) so that the core (4) is completely covered by this internal mass.
  • Sanitary napkin as claimed in claim 1 in the shape of a thin parllelopiped.
  • Napkin as claimed in claim 1 in which the fibers of the core are compressed at a pressure between 900 and 1,200 bars.
  • Napkin as claimed in claim 1 in which the absorbent mass is formed into a layer which is folded to cover the compressed core.
  • Napkin as claimed in claim 1 in which the absorbent mass surrounding the compressed core is located inside a mesh made of cotton or polyamide thread.
