Abstract
The present disclosure provides improved tape dispensers that include a case featuring a pair of opposing main plates each coupled to two circumferential wall plates. The main plates, and corresponding circumferential wall plates, are rotatable relative to one another to expose a support structure for a tape roll. A cutting blade may be provided on one of the circumferential wall plates and may include a substantially arc shaped support surface.
Claims2
A tape dispenser comprising a case operable to house a tape roll, the case including:
- a first main plate,
- a second main plate spaced from the first main plate and rotatably connected to the first main plate via a single rotation axis about which the first main plate and second main plate move in parallel orientation to one another, the second main plate having a surface,
- a circumferential wall between the first main plate and the second main plate, wherein the circumferential wall is divided along its circumferential direction into a first circumferential wall portion and second circumferential wall portion, wherein the first circumferential wall portion is integral with the first main plate, and the second circumferential wall portion is integral with the second main plate,
- a supporting rod extending from the first main plate in the direction of the second main plate, wherein the supporting rod is adapted to support a freely rotating tape roll between the first main plate and the second main plate and the location of the supporting rod on the first main plate is offset from where the first main plate is rotatably connected to the second main plate, the supporting rod extending from the first main plate and including a free end, wherein the free end contacts and engages the surface of the second main plate, and wherein the second main plate includes a protrusion connectable with the free end to limit the movement of the first main plate relative to the second main plate,
- a cutting blade disposed on the second circumferential wall portion, and
- a substantially arc shaped supporting surface disposed on the second circumferential wall portion proximate the cutting blade, wherein the inner surface of the second circumferential wall portion comprises one or more protrusions, a sand blasted surface, an embossed surface, or a release agent.
