Abstract
The present invention relates to a film cutter assembly in which a blade housing slides bilaterally along a pair of rails. The blade housing houses a blade. An elongated rail base is coupled or integral with a pair of rails. The rails are formed of a material which provides an attractive or adhesion property to attract the film to the rail and maintain the film in flat position before and after cutting. A double-side adhesive tape can be applied to a surface of the elongated rail base which is adapted for attaching the elongated rail base to a carton of film.
Claims32
A film cutter apparatus for cutting plastic wrap comprising:
- an elongated rail base;
- two rails formed at a top surface of said elongated rail base and a channel formed within said rail base;
- a blade housing including a non-rotationally mounted blade, said blade housing bilaterally slidable along said two rails, a bottom edge of an upper portion of said blade housing protruding on either end from said blade and an end surface being slanted and inclined upwardly and from either end of said bottom edge, said upper portion having no wheels, said blade is angled from a bottom edge of said blade housing and a lower sliding member to cut in both directions, said lower sliding member slidably moving in said channel;
- a portion of said two rails being formed of a first material selected from polyvinyl chloride comprising at least 10% plasticizer, plastic, rubber, silicon elastimer and combinations thereof, said first material provides cling properties to said plastic wrap received over said two rails before, during and after cutting of said plastic wrap by sliding said blade housing within said channel.
