Definitions

  • the present invention relates to sanitary napkins and the like, and has for its principal object the provision of such an article, which, while employing finely divided Wood pulp in a more or less unstratified condition, nevertheless has the properties of rigidity and cohesiveness to' a satisfactory degree.
  • the use of carded, finely divided wood pulp has long been pro osed for the present purlU pose, but of itself 1t has little cohesiveness or ody and thus requires special treatment to enable the article made therefrom to possess the above mentioned qualities.
  • One proposed way has been to form very thin felted 1;, sheets of the material in much the same way as paper is formed, and lthen forming the article from a large number of superirnposed sheets of such material. While the desirable quality of coherence is imparted to the article by this procedure', the expense involved is considerable.
  • invention aims to overcome this difliculty by employing-a core of the unstratitied material and an external layer of stronger material, also absorptive, referably of stratified wood pulp, whereby the advantages of the stratified article are substantially achieved while at the same time the cost involved is but little more than the unstratified material.
  • an external layer of stronger material also absorptive, referably of stratified wood pulp, whereby the advantages of the stratified article are substantially achieved while at the same time the cost involved is but little more than the unstratified material.
  • one or more layers of thin, unsized paper from other sources may also be em loyed for the purpose.
  • this external layer or jacket is open at the ends 40 and thus exposes the lling material, whereby disintegration of the pad is facilitated when the latter -is disposed of in a toilet, for example.
  • the jacket also eiectively prevents sifting therethrough of the wood pulp oomprising the core.
  • Figure l is a view of the unwrapped article placed uponits gauze wrapper
  • Figure 2 is 'a larger view of the unwrapped article with portions broken away;
  • Figure 3 is a View of the finished wrapped article
  • Figure 4 is a view in transverse section of the article
  • Figure 5 is a detail showinor the nature of the body portion and of the faqbric layer next to samoe.
  • 10 denotes the core of the digested wood fibre which has-been carded and formed into a felt or mat, by machinery which is well known in the art.
  • a wrapper 11 ofv stronger.material preferably, as above stated, formed of a plurality of superimposed sheets of wood fibre, Wrapper 1 1 being preferably disposed longitudinally ofthe core 10 and leaving the ends of said core open.
  • these sheets are formed as in the manufacture of unsized paper, and several thicknesses of them are placed together forming in effect a multi-ply fabric.
  • a sanitary napkin or the like composed of a core of soft, substantially finely divided, loosely coherent, digested wood pulp,
  • an enclosin jacket formed of ⁇ readily disintegrable' s eeted, digested wood Pulp, said jacket extending longitudinally o the core 5 and of the same length and leaving the ends 1 of the core exposed, and being foldedonce around the core so as to provide a, single f overlap of one longitudinal edge of the jaclet materlal beyond the other for a substantial lo portion of the wilth of one face only of the v na kin, and a gau e wrapper exterior to said jac et. f
