Abstract
A package of shirred food casing sticks Wherein the sticks are bundled together by a wrap disposed in tension transversely about the bundle and the opposite ends of the wrap are overlapped and releasably connected. The releasable connection attaches the outer surface of the underlying wrapper end to the inner surface of the overlying wrapper end and the overlying end having an outer margin which is free and loose from the connection to provide a means for grasping and pulling the overlying end free of the connector.
Claims22
A package of tubular shirred sticks of food casing comprising:
- a) a plurality of tubular shirred sticks of food casing all of substantially equal diameter arranged in a stack with the longitudinal axes of the sticks parallel to form sides of said stack and the stick ends coplanar to form ends of said stack, said sticks being arranged in rows piled one on another with the number of rows and sticks in each row being arranged to provide said stack with a preselected shape in transverse cross section;
- b) a retainer disposed in tension transversely around said stack and pressing radially inward against the periphery of said stack for bundling said sticks together and securing the shape of said stack, said retainer having an inner surface disposed against the stack periphery and an outer surface;
- c) said retainer having a first end and an opposite second end which extend generally parallel to the longitudinal axes of said sticks and which overlap along one side of said stack, said first end defining an underlayer against said stack and said second end defining an overlayer superimposed on said underlayer;
- d) connector means releasably uniting said underlayer to said overlayer, said connector means being in direct contact with the inner surface of said overlayer and with said underlayer for holding said retainer first and second ends together and maintaining said retainer in tension about said stack;
- and
- e) said overlayer having an outer margin portion extending along said second end substantially parallel with said connector means which is free of said connector means and loose from said underlayer, and said outer margin portion comprising means for grasping and pulling said overlayer for separating said connector means to open said package.

A package of tubular shirred sticks of food casing comprising:
- a) a plurality of tubular shirred sticks of food casing all of substantially equal diameter arranged in rows stacked one on another to form a desired shape in cross section;
- b) a bag composed of heat sealable plastic film having an inner surface disposed against said stack, an outer surface and a width greater than the length of said stack, said bag containing said shirred sticks, and said bag disposed in tension transversely round said stack for bundling said sticks together and securing said stack in said desired shape;
- c) said bag having first and second edges which define an open end of said bag, said edges overlapping along the length of said stock to provide respectively an underlayer and an overlayer which close said open end;
- d) a single sided adhesive tape arranged along said first edge and bonded to said overlayer and underlayer to hold them together and maintain said bag in tension about said stack;
- e) said adhesive tape being a single sided tape having a backing disposed against said stack and an adhesive surface adhered to said inner surface along said underlayer, a portion of said adhesive tape extending out from said first edge such that the adhesive thereof is in adhering contact with said inner surface along said overlayer;
- and
- f) said overlayer having an outer margin along said second edge which is free of said adhesive and loose from said underlayer, said loose outer margin comprising means for grasping and pulling said overlayer free of said adhesive for opening said package.

A method of forming a package of containing a plurality of tubular shirred sticks of food casing comprising the steps of:
- a) arranging a plurality of tubular shirred sticks of food casing, each substantially the same diameter, in a stack with the longitudinal axes of the sticks parallel to form sides of the stack and the stick ends coplanar to form ends of the stack, the sticks being in rows piled on one another with the number of rows and number of sticks in each row arranged to provide said stack with a preselected shape in transverse cross section;
- b) disposing a retainer in tension transversely around the sides of the stack to exert a radial inward pressure on the stack for bundling the sticks together, the retainer having an inner surface disposed against the stack periphery and an outer surface;
- c) overlapping opposite ends of the retainer, a first of the overlapped ends defining an underlayer against the stack and a second of the ends defining an overlayer superimposed on the underlayer;
- d) releasably connecting the inner surface of said overlayer to said underlayer for holding the opposite ends of the retainer together and maintaining the retainer in tension about the stack;
- and
- e) providing an outer margin portion of the overlayer extending along said second end which is free and loose from the underlayer, the outer margin portion comprising means for grasping and pulling the overlayer and separating it from the underlayer to open the package.
