the well known limited rotation type often used with doors where rotation between the hinge sections is due to flats on the hinges abutting sections in this instance so as to permit only about a 90 degree relative rotation between the sections the preferred angle u2296 between the base plate 18 and rigid plate 34 is in the range of 90 to 180 degrees the plates remain coplanar when the angle u2296 reaches it maximum 180 degree limit 0018 fig4 discloses an alternate system for applying pressure against the rigid plates 44 of the dispenser 40 in this embodiment there is no liner or tube used the viscous fluid 42 is confined between the relative rigid dispenser 40 walls 43 and the rigid plates 44 the spring and pressure applicator are replaced by a pair of curved levers 46 47 on either side of the rigid plates 44 that are hinged 45 together essentially centrally on a rigid lower base plate 49 the lower end of the levers 46 47 are hinged to either end 41 48 of the rigid lower base plate 49 pressure against the upper ends of the curved levers 46 47 presses the central area of the curved levers against the rigid plates 44 to press viscous fluid from the confined space 42 0019 fig5 discloses another alternate system for applying pressure against the rigid plates 64 of the dispenser 60 the upper areas of the non elastic housing 63 are provided with resilient gripping areas 66 67 at the upper areas of the rigid plates 64 for pressing the rigid plates against the viscous fluid within the confined space 62 to discharge the.
