Abstract: A magnetic adhesive tape holder includes an upper housing and a lower housing movably received in the upper housing. Two first resilient members are provided between the upper and lower housings to give the lower housing a tendency to move away from the upper housing. A clamping member is formed on the upper housing and extends into the second housing. The clamping member is in an open status when the upper housing is not pressed towards the lower housing, and in a closed status when the upper housing is pressed towards the lower housing. A first gear and a second gear are rotatably mounted on the second rear wall and engaged with each other. A cutting member is mounted on the second rear wall and beneath the first gear. A roll of magnetic adhesive tape provided in the holder can be automatically and easily cut off with a determined length.

Abstract: A portable dispenser for a roll of sheet material comprising an enclosure of rectangular shape having a rear wall, bottom wall, having a free forward edge and a cover having a rear edge hingedly mounted to the rear wall being movable between an open position and a closed position for an open position for insertion of a roll of dispensing sheet material and a closed position for dispensing sheet material including a front cutting edge and including a compressible support for supporting the roll of sheet material by compressing when the full roll is inserted and gradually expanding when the material is utilized thereby raising the roll upward and frontward toward the dispensing area of the box, including the cutting edge, said compressible support being fixed to the interior of the box, whereby frictional resistance of the sponge also diminishes reverse rolling of the roll and the resultant pulling back of the leading edge of the sheet material wherein the cutting edge is held close to the parting segment of th

Abstract: A novel tape dispenser especially useful in dispensing pressure-sensitive adhesive tape of the type having a plurality of longitudinally spaced zones which appreciably increase the force required to strip the tape from the roll compared to areas intermediate these zones. Features of the invention include: an adjustable blade on the dispenser frame, in one embodiment, which may set at desired distances from the roll to accommodate various dimensional characteristics of different tapes; a limiting structure for preventing the roll of tape from being pulled bodily out of the dispenser; and a unique arrangement for mounting and maintaining the tape such that the line of departure of tape from the roll is maintained in fixed position on the dispenser frame.In one embodiment the support means for the tape roll defines a path inclining downwardly toward a lip on the frame across which tape is drawn as it is stripped from the roll.
