Abstract
A dispenser for dispensing a material from a cored roll having a housing having a plurality of walls forming an interior volume and an opening, at least one pair of coaxially aligned, opposed plungers mounted on opposite walls within the dispenser, and a cutting mechanism. The cutting mechanism includes a blade, a cover for alternately exposing and concealing the blade, and a slidable panel for actuating the cover.
Claims15
A dispenser adapted for dispensing a material from a cored roll comprising:
- a housing having a plurality of walls forming an interior volume and an opening;
- at least one pair of opposed plungers mounted on opposite walls within the interior volume in substantially coaxially aligned, spaced apart relation, at least one plunger comprising an actuating surface disposed substantially toward the opening and a roll bearing surface disposed substantially radially opposite the plunger actuating surface;
- and
- a cutting mechanism comprising;
- a blade;
- a panel having a first end and a second end, the first end is pivotably mounted within the interior volume of the housing to at least one of said plurality of walls and is slidably movable from a first to a second position with respect to the at least one wall, the panel being disposed between the opening and the pair of opposed plungers, the panel further being slidable in at least one direction at the first end;
- and
- a cover for alternately exposing and concealing the blade, the cover having a panel contact end that is actuated by the first end of the panel slidably engaging the panel contact end of the cover, thereby causing the blade to be exposed;
- wherein the at least one plunger is adapted to retract inwardly and away from its opposing paired plunger such that application of a biasing force through the dispenser opening to the plunger actuating surface causes the roll bearing surface to be shielded, and removal of the biasing force causes the plunger to protrude toward its opposing paired plunger thereby exposing the roll bearing surface.

A dispenser for dispensing a material from a cored roll comprising:
- a housing having a plurality of walls forming an interior volume with an opening therein;
- at least one pair of opposed plungers mounted on opposite walls within the interior volume in coaxially aligned, spaced apart relation;
- and
- a cutting mechanism comprising (i) a blade, (ii) a panel having a pivotable end and a sheet contact end, the panel being pivotably attached to at least one of said plurality of walls within the interior volume of the housing at the pivotable end and further being disposed between the opening and the pair of opposed plungers, the panel further being slidable in at least one direction at the pivotable end, and (iii) a cover for alternately exposing and concealing the blade, the cover having a panel contact end;
- wherein application of a force applied to the sheet contact end in a direction substantially coplanar to a plane through the pivotable end and the sheet contact end causes the pivotable end of the panel to slidably engage the panel contact
- end of the cover and thereby actuate the cover so that the blade is exposed.
3 more elements
A cutting mechanism comprising:
- blade;
- a rigid member having a first end, the rigid member being pivotably attached at the first end and being slidable in at least one direction at the first end;
- and
- a cover for alternately exposing and concealing the blade, the cover being actuated by slidably biasing the first end of the rigid member into the cover causing the cover to retract and expose the blade;
- wherein the rigid member further comprises a second end distal to the first end and at least one cutout for engaging at least one cover stop, the cover stop having at least a first and a second actuated position wherein the first position occurs by application of a force substantially coplanar to a plane through both the first and second ends of the rigid member urging the rigid member toward the cover causing the cover stop to engage the cutout move the cover, and expose the blade.
2 more elements
A dispenser for dispensing a material comprising:
- a housing having a plurality of walls forming an interior volume and an opening;
- a blade mounted proximal to the opening;
- a rigid member movably mounted to at least one wall within the interior volume of the housing at a pivotable end, the rigid member having a sheet contact end distal to the pivotable end, the pivotable end being slidably movable from a first to a second position with respect to the housing and further being at least partially pivotable about the pivotable end;
- a cover for alternately exposing and concealing the blade, the cover having a rigid member contact end;
- wherein applying a substantially coplanar farce upon the sheet contact end of the rigid member causes the pivotable end of the rigid member to slidably engage the rigid member contact end of the cover and actuate the cover so that the blade is exposed.
2 more elements
A dispenser comprising:
- a housing having at least one pair of opposed plungers therein;
- and
- a cutting mechanism comprising (i) a blade, (ii) a panel having a pivotable end and a sheet contact end, the panel being pivotably attached to at least one wall within an interior of the housing at the pivotable end and further being disposed between the opening and the pair of opposed plungers, the panel further being slidable in at least one direction at the pivotable end, and (iii) a cover for alternately exposing and concealing the blade, the cover having a panel contact end.
