Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
157 words
A disposable training brief comprising, in combination: outer impermeable layer means; first absorbent layer means, including a first relatively thin outer absorbent layer and a first relatively thin inner absorbent layer, substantially coextensive with the outer impermeable layer; second absorbent layer means including a relatively thick absorbent layer secured to the first absorbent layer means and disposed between the first outer absorbent layer and the first inner absorbent layer for providing a relatively highly absorbent layer; waist band means for securing the training brief to a user; leg band means through which the user's legs extend; perforation means extending from the leg band means to the waist band means through the outer impermeable layer means for tearing the outer impermeable layer means for removing the training brief in case of an accident by the user, and side zones on the outer impermeable layer means adjacent to the perforation means at which the first absorbent layer means terminates.
Claim 2
Dependent Claim
157 words
A disposable training brief comprising, in combination: outer impermeable layer means; first absorbent layer means, including a first relatively thin outer absorbent layer and a first relatively thin inner absorbent layer, substantially coextensive with the outer impermeable layer; second absorbent layer means including a relatively thick absorbent layer secured to the first absorbent layer means and disposed between the first outer absorbent layer and the first inner absorbent layer for providing a relatively highly absorbent layer; waist band means for securing the training brief to a user; leg band means through which the user's legs extend; perforation means extending from the leg band means to the waist band means through the outer impermeable layer means for tearing the outer impermeable layer means for removing the training brief in case of an accident by the user, and side zones on the outer impermeable layer means adjacent to the perforation means at which the first absorbent layer means terminates.
Claim 3
Dependent Claim
25 words
The article of claim 1 in which the second absorbent layer means is secured to the first absorbent layer means remote from the side zones.
Claim 4
Dependent Claim
