referring more particularly to the drawing by characters of reference , fig1 - 3 disclose an animated dental floss dispenser 10 having a housing 11 defining a cavity 12 into which the mechanism for moving the hands 13 and mouth 14 of the animated character 15 are mounted . the purpose of the dispenser is to encourage the removal of dental floss thereby hopefully encouraging its use in a teeth flossing operation . to encourage the removal of dental floss from the dispenser the animated character is provided with a mouth that opens and closes and a pair of hands which move to simulate a flossing operation . the mechanism for opening and closing the mouth 14 of the animated character 15 as well as moving its hands 13 upon the removal of dental floss 16 from a roll or spool 17 thereof comprises a face plate 18 with mouth opening 14 mounted in an opening 19 in housing 11 . a pair of slides 20 and 21 each configured to form a lip display are slidably mounted for reciprocal movement in slots 22 and 23 of a backplate 24 . the backplate 24 is provided with teeth display 25 as shown in fig1 . the backplate 24 together with face plate 18 are fixedly secured to housing 11 by any suitable means such as , for example , screws 26 shown in fig2 and 3 . as shown in fig3 the backplate 24 is provided with a rod 27 extending axially therefrom rearwardly of the mechanism for rotatably supporting thereon a cam disk 28 having a floss engaging prongs 29 extending rearward of the mechanism and laterally thereof . a pair of arcuate slots 30 are formed in cam disk 28 , as shown in fig3 a and 4b , for receiving therein pins 20a and 21a of slides 20 and 21 for movement thereof upon rotation of the cam disk . juxtapositioned to the cam disk 28 is mounted a pendulum 31 which is pivotally rotatable about a pin 32 extending through it , a plate 33 mounted on backplate 24 rotatably supporting the hands 13 in front of the animated character 15 . a spacer 35 mounted on the bearing 36 of cam disk 28 keep the pendulum in proper spaced relationship thereto . juxtapositioned to the pendulum is mounted a star , escapement or ratchet disk 38 secured to rod 27 and comprising a floss holding spindle 39 on which is mounted the spool of floss 17 . as noted from fig2 and 3 the pendulum 31 is provided with a pair of spaced pins 40 and 41 which extend laterally thereof for engaging between the teeth of the star gear 38 . as shown in fig3 and 8 , the housing 11 is provided with a slot 42 extending therethrough in one side thereof extending from the top of the housing 43 toward its bottom 44 through which the floss 16 is withdrawn in a predetermined manner . when the floss is withdrawn a sufficient length and drawn to the bottom of the slot 42 , the piece or length of floss withdrawn may be cut off of the roll of floss by the well known cutting edge or blade means 45 mounted near the bottom 44 of the housing . in operation of the dispenser the user pulls the end of the floss 16 which is fed from spool 17 through prong 29 of cam disk 28 upward through the slot 42 near the top 43 of housing 11 . this action causes the prong 29 of cam disk 28 to rotate the cam disk to the position shown in fig4 a . the movement of cam disk 28 to the position shown in fig4 a causes the pins 20a and 21a of slides 20 and 21 to move slides 20 and 21 away from each other in slots 22 and 23 in backplate 24 exposing the teeth 25 of the animated character 15 and giving the impression of the lips opening . the movement of the floss 16 off of spool 17 which is tightly mounted on the floss holding spindle 39 causes rotation of the star disk or escapement means 38 against the rocker pins 40 and 41 on the pnedulum 31 which swings back and forth creating the &# 34 ; tick - tock &# 34 ; sound of a clock when its pins 40 and 41 are engaged and also causes the hands 13 to swing from side - to - side giving the effect that the animated character is flossing its teeth . by pulling the floss downwardly in slot 42 toward the base 44 of housing 12 to cut the piece of withdrawn floss off of the spool 17 with cutting blade 45 rotates the cam disk the other direction to the position shown in fig4 b . this action causes the slides 20 and 21 to move toward each other closing the lips of the mouth as shown in fig6 b and moves the hands 13 to the position shown in fig7 b . it will be apparent to those skilled in the art that changes and other modifications may be made to the apparatus shown and described herein without departing from the spirit of the invention or from the scope of the appended claims .
an animated dental floss dispenser capable of visually simulating the flossingg of a person &# 39 ; s teeth and the simultaneous dispensing of dental floss .
