Dispenser for adhesive products

Claim 1

A dispenser for use with a roll of pressure-sensitive tape having a plurality of longitudinally spaced zones which appreciably increase the force required to strip the tape from the roll compared to the areas intermediate said zones, said zones being substantially equally spaced apart and of substantially equal predetermined longitudinal extent thereby defining a longitudinal repeat of predetermined length, said dispenser comprising; dispenser frame means, a lip on said frame means across which tape is drawn as tape is stripped from the roll, said lip extending continuously across said frame means; support means on said frame means arranged to rotatably support the roll of tape and maintain the same against said lip along a line of contact therebetween with tape being stripped from the roll along a line of departure substantially at said line of contact; severing means on said frame means operable along a line of severing extending across the tape; said line of contact of the roll with said lip being along a free edge of said lip, the lip having a convex curved surface curving away from said free edge and merging into a horizontal support surface defining the remainder of the path of travel of the tape between said lip and said severing means, the tape being drawn across said curved surface as it is stripped from the roll; said frame means comprising an elongated flat base, a pair of transverse spaced members comprising vertical walls extending upwardly from the rear portion of said base, said tape roll support means comprising a pair of inturned horizontal flanges along the upper portions of said vertical walls substantially at the level of said lip, an annular spindle rotatably supporting said tape roll, and means on said spindle slidably but non-rotatably mounting the spindle on said flanges, said last mentioned means comprising a pair of diametrically opposed slots on each side of said spindle and receiving said flanges, and said lip being disposed relative to said severing means such that the distance from the said severing means to said lip is positionable whereby a distance is maintained equal to a whole multiple of said predetermined length of said repeat less a distance smaller than said predetermined longitudinal extent of each zone.
