Tape dispenser

A centrally tabbed adhesive tape strip pad and centrally tabbed adhesive tape flag pad in which the centrally positioned pull tab portion of the leader strip facilitates initiation of dispensing without the use of prethreaded leader bands and facilitates insertion of a new pad into typical refillable dispensers.

Method of making adhesive tape strip and tape flag pads with center tabbed leader strip

Adhesive tape strip and tape flag pads with center tabbed leader strip

A dispenser package including a stack of flexible sheets adhered together by layers of pressure sensitive adhesive with first and second ends of successive sheets in the stack adjacent; and an enclosure in which the stack of sheets is positioned having top wall portions with spaced opposed surfaces that define a wide slot. The first end portion of the uppermost sheet on the stack projects through the slot and rests against the adjacent first abutment surface. As that uppermost sheet is pulled through the slot, successive portions of it will peel away from the first underlying sheet in the stack until it contacts the second abutment surface, whereupon the first end portion of the first underlying sheet separates from the second underlying sheet, the first end portion of the first underlying sheet folds and moves through the slot with the second end portion of the uppermost sheet to leave, after the uppermost sheet is fully peeled from the first portion of the first underlying sheet, the first end portion of the first underlying sheet in a position projecting through the slot and resting against the second abutment surface in a position where it too may be grasped for manual removal in a similar manner.

Adhesive sheet pad with center tabbed leader strip

A combination of a tape dispenser including a molded polymeric frame and a cutting blade on a blade support portion of the frame, and a hanger sheet (e.g., of card stock and printed with trademark and use information) having a first end portion engaged with the frame of the dispenser, and a second portion projecting from the dispenser and having an opening adapted to receive a peg in a sales display area so that the tape dispenser can be hung from the peg by the hanger sheet. The blade support portion of the dispenser comprises a plurality of spaced projections from an inner surface of a dispenser wall that have generally coplanar distal end surfaces on which the blade is mounted. The first end portion of the hanger sheet has openings receiving the projections with the first end portion of the sheet around the projections, between the cutting blade and the inner surface of the wall supporting the projections. The hanger sheet can be separated from the dispenser by tearing it along lines of weakness intersecting those openings.

Hanger sheet and tape dispenser combination

Dispenser package

A tape dispenser having a polymeric frame with a cutter support portion having a cutting edge along one end, opposite side wall portions attached along opposite side edges of the cutter support portion, opposed hub portions projecting toward each other from the side wall portions that are adapted to project into opposite ends of an opening through a tape core to rotatably support the roll of tape, and locating tab portions projecting toward each other from the side wall portions. The locating tab portions have arcuate retaining surfaces adjacent and spaced from the support portion, and have opposed cam surfaces extending from the side wall portions to the inner ends of the locating tab portions that consistently cause tape being pulled from the roll of tape on the side of the tab portions opposite the retaining surfaces to be guided around the locating tab portions when the tape is cut, whereupon the newly cut end portion of the tape will releasably adhere to the retaining surfaces to retain that end portion in a position projecting from the roll at which it can easily be manually engaged to afford withdrawing another length of tape from the roll.

Adhesive dispenser

A stack of pre-cut sheets and a dispenser for those sheets are disclosed. The sheets include different adhesion levels to afford individual dispensing of the sheets.

Sheet stack

A refillable tape dispenser comprising a housing including a side wall, and a hub having a longitudinal axis defining an axial direction. The hub has inner and outer surfaces, and a first end fixed to the side wall. The hub comprises first and second opposed flexible portions having distal ends remote from the side wall which flexible portions project axially from the side wall. The dispenser also includes a retaining lug at the distal end of each of the flexible portions. The retaining lugs have remote ends spaced axially from the flexible portions. Ribs are present at the distal end of each of the flexible portions. The ribs project radially outward of the flexible portions and have axially extending arcuate bearing surfaces. The dispenser of the present invention is particularly suitable for coupling to a backcard having chevron-shaped openings.

Refillable tape dispenser with hub

A definite length transfer adhesive dispenser is described. The dispenser provides a convenient, hand held device that repeatedly provides a definite length of adhesive. The dispenser may be used to provide a spot of adhesive in a scrapbook or photo album. An adhesive for use with the dispenser is also described.
