Claims16
A cutting apparatus for easily opening plastic packaging comprising:
- a first support member,
- said first support member being elongate and having proximal, distal, and middle portions,
- said first support member being substantially rigid,
- said first support member having an aperture in said middle portion;
- a second support member,
- said second support member being elongate and having proximal, distal, and middle portions,
- said second support member being substantially rigid;
- means for pivotably connecting said proximal portion of said second support member to said proximal portion of said first support member;
- a second shaft,
- said second shaft being rigid, and elongate,
- said second shaft having a longitudinal axis through the center thereof,
- said second shaft having a proximal and a distal end, and a middle portion;
- means for rotatably securing said middle portion of said second shaft within said aperture in said middle portion of said first support member;
- a first cutting wheel,
- said first cutting wheel being disk shaped, rigid, and having a center portion,
- said first cutting wheel having a transverse axis through said center portion;
- a second cutting wheel,
- said second cutting wheel being disk shaped, rigid, and having a center portion,
- said second cutting wheel having a transverse axis through said center portion;
- a third cutting wheel,
- said third cutting wheel being disk shaped, rigid, and having a center portion,
- said third cutting wheel having a transverse axis through said center portion;
- a handle, said handle being securedly attached to said distal end of said second shaft;
- said first cutting wheel having a center portion being coaxially aligned with said longitudinal axis of said second shaft, and being securedly attached to said proximal end of said second shaft;
- means for said second and third cutting wheels being in rotatable connection with said middle portion of said second support member;
- whereby said first cutting wheel may engage said second cutting wheel and said third cutting wheel on opposite sides of the flange of a plastic container;
- further whereby a plastic flange may be lacerated by rotating said first cutting wheel.
