The patents of the dog diaper
are basic patents
because they comprise
structural features
not contained
in prior designs
which only propose pouches
placed under the tail
which produce friction
against the anus
and do not prevent
the leakage of waste
outside the pouch.
This pouch
on the other hand
provides an entrance
encircling
the root of the tail
and the anal region
of the dog
and a top portion
formed either
as a sleeve
or straps
which are effective
in holding the pouch
by overlying the tail
and in association with it
keep the pouch
away from the anus
and allow enough room
to comfortably
discharge the waste
and to avoid
leakage
or friction
beneath the tail.
