Claims
- 1. An encased product comprising:
- an elongated flexible casing being cylindrically shaped substantially along it length and having opposite end closures, said casing forming an enclosed product cavity;
- a product material filling said cavity and maintaining said casing in said cylindrical shape;
- said cylindrical casing being formed from an elongated strip of flexible material having opposite side edges, said strip being formed into a plurality of helical revolutions with said side edges of said strip within each one of said helical revolutions frictionally engaging and overlapping the said side edges within those of said helical revolutions adjacent said one revolution;
- said side edges being sufficiently overlapped to create enough frictional cohesiveness to maintain said strip of flexible material in a self-contained flexible casing to contain said product material.
- 2. An encased product comprising:
- an elongated flexible casing being cylindrically shaped substantially along its length and having opposite end closure, said casing forming an enclosed product cavity;
- a product material filling said cavity and maintaining said casing in said cylindrical shape;
- said cylindrical casing being formed from an elongated layer of flexible material formed into a plurality of revolutions with each one of said revolutions frictionally engaging and overlapping the adjacent revolutions;
- said side edges being sufficiently overlapped to create enough frictional cohesiveness to maintain said strip of flexible material in a self-contained flexible casing to contain said product material.
- 3. An encased product comprising:
- an elongated flexible casing being cylindrically shaped substantially along its length and forming a product cavity;
- a product material filling said cavity and maintaining said casing in said cylindrical shape;
- said cylindrical casing being formed from an elongated strip of flexible material having opposite side edges in overlapping condition to create an elongated seam;
- said overlapped side edges being sufficiently overlapped to create enough frictional cohesiveness to maintain said strip of flexible material in a self-contained flexible casing to contain said product material.
- 4. An encased product according to claim 3 wherein said casing is formed from only a single strip of said flexible material.
- 5. An encased product according to claim 3 wherein said strip is free from the application of heat, adhesives, and substances capable of chemically interacting with said casing strip during formation of said casing whereby said overlapped edges of said strip are adhered to one another only by the inherent frictional cohesiveness of said casing strip.
