The technical problem of this invention is to laminate the outer layer onto a main body of a tube, wherein a projecting portion or portions are formed, while maintaining certain uniformity. The object of this invention is to provide the laminated tube and molded tube products comprising the laminated tube, which shows the decorative effect, derived from the laminated outer layer, and enables the user to identify the tube only by touch. The outer layer is laminated onto the main body of the tube. By changing the number, width, or shape of the projecting portions, it is possible to give the decorative effect and identifiable features to the laminated tube. The laminated tube can be used to mold tube products, such as tubular containers and pouch containers.

1. A tube comprising: a cylinder-shaped substrate layer that makes up a main body of the tube; anda linear projecting portion that extends straight along an entire axial length of the tube in an axial direction, the linear projecting portion being positioned on an outer surface of the cylinder-shape
1. A tube comprising: a cylinder-shaped substrate layer that makes up a main body of the tube; anda linear projecting portion that extends straight along an entire axial length of the tube in an axial direction, the linear projecting portion being positioned on an outer surface of the cylinder-shaped substrate layer,wherein an outer layer is laminated on the cylinder-shaped substrate layer to form the tube;the linear projecting portion that extends straight along the entire axial length of the tube in an axial direction is raised on the outer layer to form a convex shape without concave portions on the outer layer;a thickness of the tube on either side of the linear projecting portion is equal, and less than a thickness of the tube at the position of the linear projecting portion such that the tube is bendable and as a result foldable at portions to either side of the linear projecting portion; andthe tube is cut to a given length, flattened and sealed at at least one end. 2. The tube according to claim 1, wherein the cylinder-shaped substrate layer is more flexible than the outer layer, which is harder than the cylinder-shaped substrate layer. 3. The tube according to claim 1, wherein a plurality of linear projecting portions are raised on the outer layer. 4. The tube according to claim 1, wherein a pair of linear projecting portions is raised axisymmetrically on the outer layer in a cross-sectional view. 5. The tube according to claim 3, wherein at least some of the plurality of linear projecting portions have different widths. 6. The tube according to claim 3, wherein an even number of the plurality of linear projecting portions are positioned at equal intervals around the main body. 7. The tube according to claim 1, wherein the outer layer gives a graded effect caused by a change in thickness of the outer layer. 8. The tube according to claim 1, wherein the cylinder-shaped substrate layer is made of an aluminum-laminated material. 9. The tube according to claim 1, wherein the main body of the tube and the linear projecting portion have different colors. 10. The tube according to claim 3, wherein the plurality of linear projecting portions are spirally disposed. 11. The tube according to claim 3, wherein the plurality of linear projecting portions have a wave form. 12. The tube according to claim 3, wherein each projecting portion has a different color. 13. The tube according to claim 1, wherein the tube is provided with a head portion at one end, the head portion including a shoulder and a neck. 14. The tube according to claim 1, wherein the linear projecting portion serves as a backbone of the main body of the tube and stably maintains a form of the tube. 15. The tube according to claim 1, wherein the outer layer and the linear projecting portion are made of the same material.
