Abstract
Abstract The disclosure relates to a process of packaging an edible product having an exposed bone by applying hot melt material to the exposed bone, encasing the product in a package, and closing the package which preferably is a bag which is heat shrunk and due to the heat shrinking operation or by the application of heat in the absence of heat shrinking the hot melt material is adhered to the bag with a bond strength greater than that between the hot melt material and the bone such that upon the removal of the bag the hot melt is removed from the bone to permit subsequent processing of the product.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A process of packaging an edible product having an exposed bone comprising the steps of applying liquid hot melt material to coat substantially only the exposed bone, encasing the thus coated product in a flexible package, said liquid hot melt material having a penetration value and being applied in an amount and to a location on the bone sufficient to provide cushioning protection for the flexible package from the bone, thereby preventing rupture of the flexible package, and thereafter adhering the hot melt material to the flexible package with a bond strength greater than that between the hot melt material and the bone whereby upon the removal of the edible product from the flexible package the hot melt material peels from the bone and remains adhered to the flexible package.
Claim 2
Dependent Claim
130 words
A process of packaging an edible product having an exposed bone comprising the steps of applying liquid hot melt material to coat substantially only the exposed bone, encasing the thus coated product in a flexible package, said liquid hot melt material having a penetration value and being applied in an amount and to a location on the bone sufficient to provide cushioning protection for the flexible package from the bone, thereby preventing rupture of the flexible package, and thereafter adhering the hot melt material to the flexible package with a bond strength greater than that between the hot melt material and the bone whereby upon the removal of the edible product from the flexible package the hot melt material peels from the bone and remains adhered to the flexible package.
Claim 3
Dependent Claim
24 words
The packaging process as defined in claim 1 including the step of heat shrinking the flexible package after the product has been encased therein.
Claim 4
Dependent Claim
39 words
The packaging process as defined in claim 2 wherein the flexible package is a bag of heat shrinkable material, evacuating the bag after encasing the product therein, thereafter hermetically closing the bag, and thereafter performing the heat shrinking step.
Claim 5
Dependent Claim
29 words
The packaging process as defined in claim 2 wherein the heat generated during the performance of the heat shrinking step adheres the hot melt material to the flexible package.
Claim 6
Dependent Claim
39 words
The packaging process as defined in claim 4 wherein the flexible package is a bag of heat shrinkable material, evacuating the bag after encasing the product therein, thereafter hermetically closing the bag, and thereafter performing the heat shrinking step.
