Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 254 words
A baby's reusable napkin for receiving a replaceable diaper, comprising: a moisture impervious outer layer and a relatively moisture absorbent inner layer having an exposed textured surface for receiving and retaining the replaceable diaper, said layers being substantially the same size and shape and secured to one another, said layers have opposing sides inwardly concavely curved along their entire length in a modified hyperbolic-like form to provide a narrow central portion straddled by the baby when the napkin is worn, the transverse axes of the hyperbolic-like curves of said sides converging toward the front of said napkin and intersecting at an angle of less than 180°, said curved sides to configuring said napkin that it is non-symmetrical about a crosswise line intersecting said sides in said narrow central portion to provide a greater area to the region of the napkin that, in use, will be adjacent the buttocks and back of the baby than to the region that will be in front, said layers having both ends arcuately inwardly curved to a lesser extent than said sides, said end of said napkin that, in use, will be adjacent the waist at the back of the baby containing an elastic construction centrally located on said end for providing a fullness to the napkin in the region that, in use, will be adjacent the buttocks of the baby, said curved ends and sides forming corner portions sufficiently extended as to permit them to be tied together about the baby for securing the napkin to the baby.
Claim 2
Dependent Claim 254 words
A baby's reusable napkin for receiving a replaceable diaper, comprising: a moisture impervious outer layer and a relatively moisture absorbent inner layer having an exposed textured surface for receiving and retaining the replaceable diaper, said layers being substantially the same size and shape and secured to one another, said layers have opposing sides inwardly concavely curved along their entire length in a modified hyperbolic-like form to provide a narrow central portion straddled by the baby when the napkin is worn, the transverse axes of the hyperbolic-like curves of said sides converging toward the front of said napkin and intersecting at an angle of less than 180°, said curved sides to configuring said napkin that it is non-symmetrical about a crosswise line intersecting said sides in said narrow central portion to provide a greater area to the region of the napkin that, in use, will be adjacent the buttocks and back of the baby than to the region that will be in front, said layers having both ends arcuately inwardly curved to a lesser extent than said sides, said end of said napkin that, in use, will be adjacent the waist at the back of the baby containing an elastic construction centrally located on said end for providing a fullness to the napkin in the region that, in use, will be adjacent the buttocks of the baby, said curved ends and sides forming corner portions sufficiently extended as to permit them to be tied together about the baby for securing the napkin to the baby.
Claim 3
Dependent Claim 27 words
A napkin as claimed in claim 1 wherein the transverse axes of the hyperbolic-like curves of said sides intersect at an angle of between 150° and 120°.
Claim 4
Dependent Claim 24 words
A napkin as claimed in claim 2 wherein the transverse axes of the hyperbolic-like curves of said sides intersect at an angle of 140°.
Claim 5
Dependent Claim 23 words
A napkin as claimed in claim 1 wherein the relatively moisture impervious outer layer is made of sheet or woven synthetic plastics material.
Claim 6
Dependent Claim 26 words
A napkin as claimed in claims 1 or 4 wheren the relatively moisture absorbent inner layer is made of a woven, knitted, or non-woven fibrous material.
Claim 7
Dependent Claim 23 words
A napkin as claimed in claim 1 wherein the inner and outer layers are bonded to one another over their entire abutting surfaces.
