Definitions
- woodpulp as the absorbent media
- One problem with utilizing fiufi'ed woodpulp as the absorbent media is that it must be encased in some material so that it will not lint or dust when handled. woodpulp is extremely light and is readily disrupted by any type of handling or air currents, etc.
- the fluffed woodpulp absorbent filler is encased in wet strength tissue or similar porous material. A layer of such tissue is placed on both the front and the back of the woodpulp and the layers secured together by embossing or adhesive means or similar techniques along their entire outer edges.
- Such encased woodpulp core makes an excellent absorbent media for most absorbent dressings or pads.
- a rectangular diaper when in use, has its widthwise ends encircling the babys waist and pinned together at each side.
- the encircling of the babys waist places stress on the diaper in the direction of its width. This stress causes no problems with the waterproof backing or absorbent facing; however, the wet strength tissue utilized to encase the woodpulp is extremely weak and this stress will tear the tissue along its edges. The tears allow the fine woodpulp to dust out and lint and get into the atmosphere and onto the babys skin.
- My new diaper has a waterproof backing sheet and an absorbent facing sheet.
- the sheets are substantially coextensive and are secured along their longitudinal edges.
- the absorbent media comprises woodpulp encased in absorbent porous tissue.
- My absorbent pulp core encased in tissue extends across only a portion of the width of the diaper and does not extend to either longitudinal edge of the waterproof backing sheet or the absorbent facing.
- the absorbent core is situated approximately in the middle of the width of the facing and backing sheets.
- FIG. I is a face view in perspective of the back of my new diaper
- FIG. 2 is a partially cut away plan view of the reverse side of the diaper as shown in FIG. 1;
- FIG. 3 is an enlarged schematic cross-sectional view taken along line 3-3 of FIG. 1.
- a diaper comprising a waterproof backing sheet 11 and an absorbent facing sheet 12.
- the two sheets are substantially coextensive and the waterproof backing sheet overlaps the longitudinal edges 13 of the facing sheet and is secured thereto by means of adhesive.
- Disposed between the facing and backing sheets is the absorbent core 14.
- the absorbent core comprises a layer of woodpulp fibers l5 completely encased in wet strength tissue 16.
- the upper and lower layers of tissue are secured together at all open edges to make a completely enclosed woodpulp core.
- the edges 17 of the tissue may be embossed to secure them together and encase the woodpulp.
- the core extends substantially the entire length of the diaper and is spaced substantially in the center of the facing and backing sheets.
- the center portion of the longitudinal edges fits between the legs of the baby and the upper and lower ends of the diaper encircle the waist of the baby and are pinned together at the waist.
- the ends of the diaper may be tightly pinned together and considerable tension placed on the waist encircling portions without disrupting or tearing the tissue which encases the woodpulp and hence, eliminate any problems of dusting or linting of woodpulp onto the baby's skin.
- the facing sheet may be any soft, moisture permeable material such as a nonwoven fabric either intermittently or overall bonded, a wet strength tissue paper, or similar material.
- the backing sheet may be any of the waterproof materials and is usually a thin film of polyethylene or polypropylene, or similar material.
- the longitudinal edges of the facing and backing sheets may be secured together either by overlapping the facing sheet on the backing sheet or the backing sheet on the facing sheet as desired or, in fact, making them absolutely coextensive and then securing them along their longitudinal edges by any means known in the art, i.e., sewing, adhesives, heat-sealing etc.
- the absorbent media is fluffed woodpulp and is encased in any of the various tissue papers preferably those which have wet strength.
- the tissue is sealed along all of its open edges to encase the woodpulp by gluing, embossing, etc.
- the absorbent media may be backed by a wet strength tissue which extends the full width of the diaper and adds to the absorptive capacity of the diaper.
- the absorbent media may be secured to the backing by adhesive or glue, or other means well known in the art.
- a substantially rectangular disposable diaper comprising a thin, waterproof backing sheet and a thin, moisture permeable facing sheet, said backing sheet and said facing sheet being substantially coextensive and being secured together along their longitudinal edges, and an absorbent core disposed between said facing and said backing sheets extending the entire length of said sheets but only across a portion of the width of said sheets, said absorbent core comprising a center layer of fluffed woodpulp fibers encased in outer layers of tissue said outer layers being secured together at all open edges, said waterproof backing sheet being a polyolefin film and said facing sheet being a nonwoven fabric and wherein said film overlies said nonwoven fabric along the longitudinal edges thereof and is secured thereto and wherein the center layer of woodpulp fibers is encased in wet strength tissue which is embossed along its open edges.
- a substantially rectangular disposable diaper comprising: a thin, waterproof polyolefin backing sheet; a thin, absorbent, moisture permeable nonwoven fabric facing sheet, said backing sheet overlapping the longitudinal edges of said facing sheet, with said backing sheet and said facing sheet having the same length and being substantially coextensive and being adhesively secured together along their overlapped longitudinal edges; and an absorbent core disposed between and in direct contact with said facing and said backing sheets extending the entire length of said sheets but only across a portion of the width of said sheets, said absorbent core comprising a center layer of fluffed woodpulp fibers completely encased in outer layers of wet strength tissue paper, said outer layers of wet strength tissue paper being secured together at all open edges to completely encase the layer of woodpulp fibers, said layers the waist of an infant do not contact the wet strength tissue paper to tear or rip the same and expose the layer of woodpulp fibers.
