Abstract
An absorbent panel for pet animals such as dogs and cats comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent core panel therebetween, the core panel having a relatively thin central region and a relatively thick side region.
Description
~ 2181954 AF~S~ hl~ PANEl~ FOR PET ANIM~S
Field of the Invention The present invention relates to an absorbent 5 panel for pet animals such as dogs or cats and more par-ticularly to a panel for absorbing and holding liquid excretion, for example, urine of pets bred indoors.
Back~round of the Invention Japanese Laid-Open Utility Model Application No.
Hei4-673 discloses an absorbent panel for pet animals comprising a liquid-absorbent sheet which comprises, in turn, two sheets of blotting paper with superabsorptive polymer powder disposed between the sheets, and a water-proof sheet bonded to a lower surface of the liquid-absorb-ent sheet.
However, most conventional urine absorbent sheets such as the sheet disclosed in the above-mentioned Japanese Laid-Open Utility Model Application, tend to absorb urine discharged onto a central region of the sheet and have no ef f ective means f or preventing sideways leakage of urine possibly discharged onto a peripheral region of the sheet.
Pet animals insufficiently trained to use such a sheet of ten urinate on the peripheral region of the sheet and consequently ,.,nt~m;n~te the room in which the panel ia placed . Thus the obj ective of the absorbent panel is not always achieved.
Summary Qf the Invention Accordingly, it is a principal object of the invention to avoid the sideward leakage of urine from the peripheral region of the absorbent panel.
According to the inverltion, there is provided an absorbent panel for pet animals compri~ing a liquid-per-meable topsheet, a liquid-impermeable ba~kqhf~et and a liquid-absorbent core panel disposed between the two sheets, wherein the core panel comprises a relatively thin central region and a relatively thick side edge region ~ 2~81954 which occupie8 more than half of a periphery of the core panel and has a width at least of 2 Omm .
According to a pref erred embodiment of the invention, the side edge region is at least 1. 5 times as 5 thick as the central region and cnntA;n.q at least 30g/m2 of superabsorptive polymer powder.
Brief Deacription o~ th~ Drawinaa Fig. 1 is a perspective view showing an absorbent 10 panel in accordance of the invention, with the top sheet partially broken away in the lower front corner;
Fig. 2 is a sectional view taken along line II-II
in Fig. 1; and, Fig. 3 is a perspective view showing an alterna-15 tive embodiment of the ;lhs~rh~n~ panel.
De~;led Desc~i~tion of the Preferred Embo~l;r-n~
Referring to Fig. 1, a rectangular absorbent panel 1 for indoor use in absorbing urine excreted by pet 20 cats or dogs comprises a liquid-permeable topsheet 2 made of a nonwoven fabric, a liquid-; ~ hle backsheet 3 made of a plastic film and a liquid-absorbent core panel 4 disposed between the two sheets 2, 3. The core panel 1 is defined by longitudinally opposite ends 5 and transversely 25 opposite side edges 6. The core panel 1 has a relatively thin central region 10 and relatively thick side edge region 11 completely surrounding the central region 10.
The top and backsheets 2, 3 extend outward beyond a periph-eral edge of the core panel 4 and have their opposite inner 30 surfaces watertightly heat-sealed to each other.
Referring to Fig. 2, the central region 10 of the core panel 4 has a thickness of 't~ while the side edge region 11 surrounding the central region 10 presents a trapezoidal cross-section having a width ~W~ of at least 35 20mm and a thickness 'T' at least equal to 't' x 1.5.
While the thickness ~ t ~ may be appropriately selected, it is preferred to select the thickness 't~ in a range of 1 to ... , . . . . . . _ _ .. . .. . _ _ _ _ _ _ . . .
lOmm, and the thickness ' T' is preferably selected in a range of 1.5 to 20mm. The central region 10 mainly com-prises fluff pulp fibers 13 and may comprise additional materials such as superabsorptive polymer powder 14 up to 15g/m2 or thermoplastic synthetic fibers 15 up to 209~ by weight. In the core panel 4, the superabsorptive polymer powder 14 is preferably distributed with an unevenly high density adjacent the backsheet 3 and, particularly in the side edge region 11, 50 or higher 96 by weight of the polymer powder 14 is preferably r~)nr~ntrated into a lower half of its thic-k-ness~ It is assured thereby that a quantity of urine having been quickly absorbed by the fluff pulp f ibers 13 moves into the superabsorptive polymer powder 14 without sideward leakage from the absorbent panel 1. The top and h~rk~ ts 2, 3 are respectively bonded at desired locations to the core panel 4 or bonded to each other on a predetermined line along which the core panel 4 has been partially cut away ~o as to ~;nt~;n the core panel 4 in a desired conf iguration . An embodiment of the core panel 4 including thermoplastic synthetic fiber~
advantageously promotes spreading of urine along the pulp fibers 13, allows the top and backsheets 2, 3 to be bonded to the core panel 4 by means of heat-sealing and allows the core panel 4 to be molded under the ef f ect of heating .
Referring to Fig. 3, in this rectangular panel 1, the side edge region 11 has said thickness ' T' merely along transversely opposite side edges 6 and longit~ ;n~lly opposite ends 5 have substantially the same thickness as that of the central region 10.
To implement the invention, not only a nonwoven fabric but also a perforated plastic film or the like may be used as material for the topsheet 2. Bonding of the respective members can be achieved by using an adhesive agent such as hot melt type adhesive or a heat-sealing technique so far as the heat-sealable material is con-cerned .
The absorbent panel of the invention i8 unique in that the panel 1 is thicker in the side edge region 11 than in the central region 10 and a substantially larger quan-tity of the superabsorptive polymer powder is distributed 5 in the side edge region 11. Such an arrangement effective-ly blocks a quantity of liquid excretion which otherwise might tend to leak sideways f rom the panel ' 8 periphery, enabling the superabsorptive polymer powder to absorb such liquid excretion and thereby prevent further 8ideways 10 , v t of the liquid. The absorbent panel of the inven-tion can be used for pet animals insufficiently trained to use this panel without contaminating the room in which this panel is placed, since undesirable sideward leakage of liquid excretion is reliably avoided even if liquid excre-15 tion is discharged onto the panel at a location adjacentthe side edge region thereof.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this 20 invention without departing from the spirit or scope thereoi. Accordingly, the scope of the invention is to be construed in accordance with the ~ubstance def ined by the following claims.
