The tube portion comprises a continuous coating that is a permeation barrier to the semi-solid composition, which is disposed between the first and second plies and the second and third plies. The container also includes a restrictor portion sized and dimensioned to couple with the open end of the tube portion and an end closure member sized and dimensioned to mate with the restrictor portion. The tube portion, restrictor portion, and end closure are made of one or more biodegradable materials. ## Claims ### Claim 1 A biodegradable container for a semi-solid composition, comprising: a tube portion comprising a first paper that defines first, second, and third plies forming an open end and a closed end, and a lumen containing the semi-solid composition, wherein the tube portion further comprises a continuous coating that is disposed between the first and second plies, and between the second and third plies, and wherein the coating is a permeation barrier to the semi-solid composition; a restrictor portion sized and dimensioned to couple with the open end of the tube portion; an end closure member sized and dimensioned to mate with the restrictor portion; and wherein each of the tube portion, restrictor portion, and end closure member is biodegradable and are made of one or more biodegradable materials. ### Claim 2 (depends on 1) The container of claim 1, wherein the tube portion has a wall thickness of no more than 0.5 mm. ### Claim 3 (depends on 1) The container of claim 1, wherein at least one of the tube portion, restrictor portion, and the end closure member comprise at least one of a fibrous material, molded cellulose fiber, vulcanized latex, and vegetable polymer. ### Claim 4 (depends on 1) The container of claim 1, wherein the closed end of the tube portion has a transverse seal. ### Claim 5 (depends on 4) The container of claim 4, wherein the transverse seal is formed by at least one of crimping and folding. ### Claim 6 (depends on 1) The container of claim 1, wherein at least one of the tube portion and restrictor portion has a biodegradable liner that includes a permeation barrier to the semi-solid composition. ### Claim 7 (depends on 1) The container of claim 1, wherein the tube portion is impregnated with vulcanized latex. ### Claim 8 (depends on 1) The container of claim 1, wherein at least one of the restrictor portion and end closure member have a second coating. ### Claim 9 (depends on 8) The container of claim 8, wherein the second coating comprises an adhesive. ### Claim 10 (depends on 8) The container of claim 8, wherein the second coating comprises a metal layer. ### Claim 11 (depends on 8) The container of claim 8, wherein the second coating is biodegradable. ### Claim 12 (depends on 8) The container of claim 8, further comprising a third coating disposed on an outside surface of the tube portion. ### Claim 13 (depends on 8) The container of claim 8, wherein the second coating is impregnated within the tube portion. ### Claim 14 (depends on 1) The container of claim 1, wherein the end closure member comprises at least one of a cork stopper, a latex rubber stopper, and a molded vegetable polymer screw cap. ### Claim 15 (depends on 11) The container of claim 11, wherein the end closure member further comprises a flip top end closure member that is coupled to the restrictor portion by a flexible attachment. ### Claim 16 (depends on 1) The container of claim 1, wherein the restrictor portion comprises a first, second, and third ply of a second paper. ### Claim 17 (depends on 16) The container of claim 16, wherein the coating is biodegradable. ### Claim 18 (depends on 1) The container of claim 1, wherein the restrictor portion is molded from a pulp slurry. ### Claim 19 (depends on 1) The container of claim 1, wherein the coating is an adhesive that affixes the first ply to the second ply, and the second ply to the third ply. ### Claim 20 A biodegradable container for a semi-solid composition, comprising: a tube portion comprising a first paper that defines first, second, and third plies forming an open end and a closed end, and a lumen containing the semi-solid composition, wherein the tube portion further comprises a continuous, biodegradable coating that is disposed between the first and second plies, and between the second and third plies, and wherein the coating functions as a permeation barrier to the semi-solid composition; a restrictor portion sized and dimensioned to couple with the open end of the tube portion; an end closure member sized and dimensioned to mate with the restrictor portion; and wherein the tube portion, restrictor portion, and end closure member are made solely of one or more biodegradable materials.
