Abstract

A package comprising tubular food sheath fibers encased in a plastic film, the film comprising the fibers, the package which is provided with a release strip secured to the outer surface of the film; the attenuated areas are provided in the film as along the parallel edges of the release strip so that pulling the release strip away from the packing causes the film between the attenuated areas to be removed with the strip thereby removing the packing and exposing the fibr

Description

PLASTIC CARRIER EASY TO OPEN Background of the Invention This invention relates to packages for food covering fibers. Food cover fibers without shirred tubular film food covers "Shirred" means radially folded means to be compressed along the longitudinal axis of the tubular film Such shirred food covers are packaging for storage and shipping for food processors. example meat packers who produce cylindrical stuffed products Numerous types of pouches have been used for shirred food cover in the prior art Such packages have included rigid cartons as well as web and film wrappers Film wrappers have had certain disadvantages, for example Examples are lightweight and usually provide a moisture barrier to prevent dehydration of wetted fiber products. A difficulty with film wrapping for food coated filaments has been that a film that is strong enough to provide a packing insurance It is generally difficult to remove from the packaged product. This problem has been addressed by providing adhesive strips or opening areas that can be easily removed to provide access to the contents of the package. Unfortunately such adhesive strips have caused another problem in which after removal they tend to adhere to undesirable areas creating disorganization and a generally messy environment. It is therefore an object of the invention to provide an easily openable film package for food covering fibers that overcomes the disadvantages of prior art film packages.

Brief Description of the Drawings Figure 1 shows a package of food covering fibers to be packaged in accordance with the present invention. Figure 2 shows a closed package embodiment of the present invention. Figure 3 shows a heat sealed embodiment of the invention. the invention The invention comprises a package consisting of tubular food sheath fibers encased in a plastic film, the film comprising said fibers, the package which is provided with a release strip secured on the outer surface of the film, the attenuated areas being provided in the film along parallel edges of the release strip so that pulling the strip away from the package causes the film between the attenuated areas to be removed with the strip thereby opening the package and exposing the fibers Detailed description of the invention The shirred tubular film to be packaged in accordance with the present invention may be of any suitable material for example, cellulose film or collagen and may or may not be reinforced for example with fiber dispersed randomly or in the form of a braided or non-woven fabric The tubular film can be used to pack any suitable food product, for example, sausages such as "hot dogs", smoked sausages, salami, fresh sausage cold cuts etc, whole foods such as hams or turkey breast or other product such as cheeses. The fibers may be any natural or synthetic plastic film, for example, cellophane-type film, polyethylene, polyvinyl chloride, etc. The plastic film can have shrink wrap characteristics, for example, the fibers can be placed in a tubular plastic film and the film shrunk on the fibers to provide a secure containment. The film can also have extension characteristics so that it can spread on the fibers and then relax to secure the fibers In accordance with a preferred embodiment of the invention, the film wrap extends over the ends of the fibers and is secured, for example clamped, glue-bonded, heat-sealed or tied over the ends to provide a liquid-tight package. The ends of the gasket are preferably heat sealed so that the sealed portion is in a plane that is essentially parallel to a plane. defined by an edge of the sealed portion of the release strip When the release strip and the heat seal have a relative orientation, it has unexpectedly been found that the fibers are more easily released from the package after removal of the strip It is understood, however, that the rapid opening feature of the invention can be used whether or not the package is sealed on the ends of the fibers. The release strip is generally secured to the plastic film by heat or adhesive. activated by catalyst and an attenuated area, for example a thin film area or perforation s, such as punctures or slits are provided along both edges of the release strip. The release strip can be of material equal to or different from that of the film. For ease in securing the release strip, at least one end thereof is not attached to the film in a desirable manner The release strip can be essentially in any orientation on the film for example radial or longitudinal or diagonally oriented However, the strip is usually oriented parallel to longitudinal axes of the packed fibers and the entire length of the fibers is usually extended. The invention can be better understood by reference to the preferred embodiment illustrated in the drawings. Figure 1 shows a package 10 of gathered fibers 12 to be incorporated within a package 14 as they are comprised by the film. plastic 18 as shown in Figure 2 Such fibers have longitudinal axes 16 and ends 17 The release strip is secured on the outer surface 22 of the film 18 The attenuated areas 24 in the form of perforations are provided in the film 18 along parallel edges 26 of the release strip 20 The release strip 20 it is not secured to the film at one end to provide a pull tab 28 to easily hold and detach the release strip. Preferably the strip extends at least the entire length of the longitudinal axes 16. In a preferred embodiment, as shown in Fig. 3, the film 18 extends beyond the ends 17 of the fibers and is heat sealed . In this embodiment, the extreme heat seals 30 are provided being in a plane 32 which is essentially parallel to an edge 26 of the release strip 20 essentially parallel means within a deviation of 10 ° from the parallel and includes the mode where the plane contains an edge Surprisingly and unexpectedly, the perforations 24 when they are of a sufficiently small size, for example a cut of 0.127 cm / 0.635 cm of junction, does not allow the passage of important moisture from the fibers of the packaging towards the external environment
