Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
An animated dental floss dispenser comprising: a hollow housing displaying an animated character through an opening therein; said character having a mouth opening, a mechanism for animating said character, said mechanism comprising a backplate mounted behind said animated character and having a pair of sliding plates mounted thereon for opening and closing said mouth opening, said plates having pins extending laterally therefrom, a cam disk mounted adjacent said plate for moving said pins and said slide plates in a predetermined direction, said cam disk comprising a prong for engaging a piece of floss passing thereover for rotation of said cam disk upon predetermined movement of said floss, and a spool of floss mounted adjacent said cam disk, said housing having a slot extending therethrough, whereby when a piece of the floss from said spool is fed over said prong and through said slot and is pulled toward one end of said slot, said cam disk causes movement of said slide plates relative to each other in one direction and when the piece of floss is pulled toward the other end of said slot, said cam disk causes relative movement of said slide plates in the other direction to open and close said mouth opening of said animated character.
Claim 2
Dependent Claim
208 words
An animated dental floss dispenser comprising: a hollow housing displaying an animated character through an opening therein; said character having a mouth opening, a mechanism for animating said character, said mechanism comprising a backplate mounted behind said animated character and having a pair of sliding plates mounted thereon for opening and closing said mouth opening, said plates having pins extending laterally therefrom, a cam disk mounted adjacent said plate for moving said pins and said slide plates in a predetermined direction, said cam disk comprising a prong for engaging a piece of floss passing thereover for rotation of said cam disk upon predetermined movement of said floss, and a spool of floss mounted adjacent said cam disk, said housing having a slot extending therethrough, whereby when a piece of the floss from said spool is fed over said prong and through said slot and is pulled toward one end of said slot, said cam disk causes movement of said slide plates relative to each other in one direction and when the piece of floss is pulled toward the other end of said slot, said cam disk causes relative movement of said slide plates in the other direction to open and close said mouth opening of said animated character.
Claim 3
Dependent Claim
23 words
The animated dental floss dispenser set forth in claim 1 wherein: said animated character is formed in the likeness of a toothie character.
Claim 4
Dependent Claim
22 words
The animated dental floss dispenser set forth in claim 2 wherein: said slide plates are formed as lips of the animated character.
Claim 5
Dependent Claim
92 words
The animated dental floss dispenser set forth in claim 1 in further combination with: a pendulum pivotally mounted adjacent said cam disk, means for rotatively mountiing a spool of dental floss adjacent said pendulum, a spool of dental floss mounted on said means, the dental floss when pulled from said spool causing said means to rotate said pendulum back and forth through an arcuate path, a pair of hands mounted in front of said mouth opening, and means connecting said hands to said pendulum for predetermined movement upon movement of said pendulum.

The animated dental floss dispenser set forth in claim 5 in further combination with: means for loosely mounting said pendulum on said cam disk so that when said ratchet gear sequentially engages said pin means on said pendulum a tick-tock sound is generated.
Claim 8
Dependent Claim
53 words
The animated dental floss dispenser set forth in claim 1 in further combination with: a pair of arcuate slots formed in said cam disk with one of said pins of said slide plates extending into each of said arcuate slots, whereby rotation of said cam disk causes predetermined movement of said slide plates.
