Abstract
A package opener having a rotating cutting wheel and adapted to cut and open packages having dye cut edges/flanges, or more specifically clamshell packages. An opposing groove is positioned to receive the blade of the cutting wheel. The package opener includes an edge receiving portion that is configured to receive the flange of the package and allow the opener to be moved along the same. The moving action results in an engagement of the package between the cutting wheel and the opposing groove, and the cutting of the same without any exertion or discomfort to the user.
Claims20
A package opener comprising:
- a cutting wheel having a blade;
- a friction wheel;
- and
- a package receiving portion for receiving a flange of the package;
- wherein when the flange of the package is disposed in said receiving portion, the package opener is moved along the flange to cut open the same.
A package opener comprising:
- a cutting wheel having a blade;
- a friction wheel;
- and
- trigger means attached to one of said two wheels for selectively retracting said wheel from an operable cutting position and extending said wheel into the operable cutting position;
- wherein when said trigger is in a retracted position, said wheels are separated to enable the insertion of the package edge into said slot and between said wheels, and wherein when said trigger is activated to the extending position, said wheels engage and the cutting wheel blade engages the surface of the package flange to cut the same.
A package opener comprising:
- a cutting wheel having a blade and gearing;
- a friction wheel having a slot having at least one edge and gearing meshed with said cutting wheel gearing, said slot adapted to receive said blade along said at least one edge;
- a motor connected to at least one of said wheels;
- and
- actuator means for selectively activating said motor thereby causing both of said wheels to rotate via said gearing.
A package opener comprising:
- a cutting wheel having a blade;
- a rack having a groove for receiving said blade;
- and
- a package receiving portion for receiving a flange of the package;
- wherein when the flange of the package is disposed in said receiving portion, the package opener is moved along the edge to cut open the same.
A package opener comprising:
- a cutting wheel having a blade;
- a rack having a groove for receiving said blade;
- a package receiving portion for receiving a flange of the package;
- trigger means connected to said cutting wheel and adapted to selectively raise and lower said cutting wheel;
- wherein said trigger means enables said blade to disengage from said rack and allow insertion of the package flange in between said cutting wheel and said rack.
