- the number of the convex portions 4 provided at equal intervals is an even number
- the number of the groove portions 5 between the convex portions 4 can be even, so that the laminated tube 1 can be easily flattened using the convex portions 4 as a guide.
- This is convenient for forming the tube container 9 or the bag container 10 (see FIG. 10).
- the tube container 9 or the bag container 10 can be crushed by using the protrusion 4 as a guide, so that the contents are pushed out neatly from the tube container 9 or the like. The handling of the tube container 9 and the like is improved.
- the bag container 10 can be formed from the laminated tube 1.
- the laminated tube 1 is cut into a predetermined length, one end of the laminated tube 1 is crushed flat and closed, and after storing the contents, the other end is similarly crushed flat and closed, and sealed.
- a bag container 10 with both ends crushed flat in the same direction, or Fig. 11 As shown in (1), a bag container 10 can be formed in which one end and the other end are crushed flat so as to be orthogonal.
- FIG. 12 shows a sixth embodiment of the present invention, and is a longitudinal sectional view of the laminated tube 1.
- the laminated tube 1 has another layer 3 forming a convex portion 4 having a different thickness in the axial direction on a base layer 2 constituting a tube main body.
- the thickness of the projections 4 can be changed by appropriately changing the extrusion pressure of the other layer 3, and in the coating method, the degree of vacuum suction is changed. Thereby, the thickness of the convex portion 4 can be changed.
- the convex portion 4 becomes light and shade, and the gradation improves the decorativeness of the laminated tube 1.
- FIG. 13 shows a seventh embodiment of the present invention, which is a laminated tube 1 on which corrugated convex portions 4 are formed.
- FIG. 14 shows an eighth embodiment of the present invention, which is a laminated tube 1 in which a spiral convex portion 4 is formed.
- the spiral tube 4 can be formed, and not only the linear and wavy shapes, but also the decorativeness of the laminated tube 1 can be improved. The appearance can be improved.
- FIG. 15 shows a ninth embodiment of the present invention, which is a laminated tube 1 in which the projections 4 have different colors for each of the projections 4.
- the multi-layered tube 1 can be colored with multiple colors.
- a pattern such as a stripe shape or a wavy shape is formed, so that the decorative property of the laminated tube 1 can be improved and the design property can be improved.
- the laminated tube 1 in which two colors are alternately applied to each of the convex portions 4 is shown.
- the present invention is not limited to this example, and a plurality of colors may be repeatedly applied to each of the convex portions 4. All colors may be different for each part 4, or a plurality of colors may be randomly applied to each convex part 4. The invention's effect
- the present invention has the above-described configuration, the following effects can be obtained.
- the first aspect of the present invention since another layer is formed on the outer surface of the base material layer constituting the tube main body to form an axially continuous projection, irregularities are formed on the outer surface of the tube main body.
- the decorativeness of the tube and the appearance of the tube are improved, and the laminated tube can be identified only by touch.
- the convex portion is formed. It functions as a support member for the tube body, and can stably maintain the shape of the tube.
- the laminated tube can be easily crushed using the convex portion as a guide.
- the decorativeness of the laminated tube is further improved. Also, if a tube container or bag container is formed from the laminated tube • and the number of convex parts of the container, which is a molded product, is determined by simply touching the tube container, It is possible to identify the contents stored in the container, it is convenient for people with visual impairment, etc. This is convenient when using different tube containers and the like.
- the convex portion since the convex portion is provided axially symmetric, the laminated tube can be crushed flat along the axially symmetric convex portion, and the laminated tube has a predetermined length. It is easy to form a tube container or a bag container which is cut into pieces and closed at one end. In addition, when removing the stored items from the formed tube container or bag container, the convex portion serves as a guide to easily crush the tube container or the bag container. It is easy to extrude and the handling of tube containers or bag containers can be improved.
- the convex portions having different widths are formed on the base material layer constituting the tube main body, decorativeness and appearance can be improved. Characters and the like can be printed on the portion.
- the convex portions are provided at equal intervals on the base material layer constituting the tube main body, a stripe-like pattern is formed on the entire tube, and the decoration of the laminated tube is performed. Performance can be improved.
- the convex portion having the shading due to the change in thickness is formed on the base material layer constituting the tube main body, the convex portion forms a gradation, and the decorative property of the laminated tube is improved. Can be improved.
- the tube main body by forming the tube main body from an aluminum laminated material, another layer forming a convex portion is provided in the tube main body of the aluminum laminated material, and the convex portion is used as an aggregate.
- the aluminum laminate tube can be reinforced, and the a section is provided on the aluminum laminate material exhibiting metallic silver, so that decorativeness can be improved and a sense of quality can be obtained.
- the other layer forming the convex portion is laminated with a different color on the base material layer constituting the tube main body, not only the uneven shape, Since the convex portions can be clearly recognized also by the color, the decorativeness can be improved.
- a corrugated convex portion is formed on the base material layer constituting the tube main body, and in the invention according to claim 12, the spiral convex portion is formed. Since it is formed, not only a linear convex part but also a convex part of various shapes can be formed, and the decorative property and the visual fun of the laminated tube can be improved.
- the convex portions are made different colors for each of the convex portions, a plurality of colors form a colorful pattern such as a stripe shape and a wavy shape, so that decorativeness is improved. I do.
- a tube container or a bag container having a high design property can be formed by using the laminated tube in consideration of the decorative property.
