- The present invention relates generally to the field of packaging for a food product comprising a film substantially surrounding the food product that is intended to be easily openable and/or closable. One embodiment of the invention includes flaps that are reclosable with adhesive. Another embodiment includes tear strips formed, for example, by perforations that partially penetrate the packaging material. Another embodiment includes a device such as a blade or flexible member (e.g., ribbon, string, wire, etc.) configured to cut (tear, rip, etc.) through all or a portion of the packaging. Another embodiment includes closure (or reclosure) devices (e.g., clips, adhesives, ties, etc.). Any of these components may facilitate the opening of a packaging in a longitudinal fashion (e.g., in a direction generally parallel to a longitudinal axis of or along a length of a package or food product), a lateral fashion (e.g., perpendicular to a longitudinal axis, radially about a longitudinal axis, and/or radially in a plane that is perpendicular to a longitudinal axis of a package or food product), a combination of longitudinal fashion and lateral fashion (e.g., in a spiral or helix direction along exterior surface), or an any other direction, fashion, or manner.
- As used in this description, “food product” or “prepared foods” includes whole, ground, blended, and/or emulsified meat and non-meat products (e.g., soy-based protein) in a an extruded or otherwise formed roll, commonly referred to as a “chub” that is packaged in an outer skin, film, or wrapper. The application is directed to ripping, cutting, puncturing, or otherwise opening the film to expose the food product so that it may be used by a consumer. According to other exemplary embodiments the film may be used to house another food product such as cookie dough. One or more package opening facilitators (e.g., perforations, cutting devices, tear ribbons, weakened portions of material, notches, cuts, scores, etc.), may be used according to the various embodiments described herein, the features of which may be used alone or in any combination.
