Description of the new type: [Technical field to which the new type belongs] This creation is about the composition of a kind of inner and outer double-layer paper tube. A kind of first combination on the top surface of the bottom of the paper tube-a metal plate. The inner wall of the bottom edge of a cylindrical inner layer body is directly inserted into the edge; the edges are closed, so the wire has a double-layer hollow paper tube. Side wall knot [Previous technology] According to the characteristics of the material of the paper tube, it is quite suitable for storage and storage. Generally speaking, the paper tube is formed by a cylindrical body and a round transport special bottom combined by a metal joint. As shown in the first figure of the flat plate, it is formed by the bottom edge of the wall of the cylinder 1G and the coupling member 2q: the structure is 21 as an insert combination, and then from the side of the coupling member 20 together with: Groove out: the bent concave portion 22 which is obviously concave, so that the tube body 10 and the coupling member are firmly connected together; then, the bottom 30 of the paper tube is opened from the inside of the first channel to the bent concave portion. In the end, it will be combined with the tube body 10 5 M264233 [New content] The main purpose of this creation is to provide an inner and outer double-layer paper tube, which can be used to accommodate different items to expand its applicability . Another purpose of this creation is to provide an inner and outer double-layer paper tube. After the assembly is completed, the inner tube body can form a reel shaft, which can be used to store linear items. The outer tube body is formed. The wall of the linear article is covered, so it is particularly suitable for this storage purpose. The structure of this creation is that the paper tube includes: an outer tube body; a coupling piece that is combined with the outer tube body; a bottom portion that is placed inside the bottom edge of the outer tube body; The wall of the body is deformed in a recessed manner, and the common clamping = the bottom forms the stable combination of the outer cylinder with the joint and the bottom; the improvement focuses on the combination of a metal disk on the top surface of the bottom Body has an upwardly protruding side wall; an inner layer cylinder body, the inner wall of the bottom edge of the wall body is directly inserted and combined with the side wall, so the inner layer body defines a built-in space, and the inner and outer cylinder bodies An external space is defined to form an inner and outer double-layer paper tube. In the above-mentioned structure, the side wall of the metal disc body protruding upward is further formed with convex-shaped reinforcing ribs to strengthen the binding effect with the inner cylinder. In the above structure, wherein the top edge of the side wall of the metal disc body protruding upward forms a push-in edge that is slightly inclined inward, so as to facilitate the sleeve insertion of the inner cylinder body to be completed smoothly. [Embodiment] Regarding the technical means and effects used in this creation to achieve the above-mentioned purpose, the following preferred and feasible embodiments are described in detail with reference to the drawings, so that they can be fully understood. Please refer to the second figure, this creative embodiment is an inner and outer double-layer paper tube. 6 M264233 is structured to include the outer tube body 40 with the same structure as the previous conventional example, the joint 50 and the bottom 60; The coupling member 50 uses its cylinder groove 51 for the bottom edge of the outer cylinder body 40 to be inserted and combined. The side of the coupling member 50 together with the outer cylinder body 40 forms a bending recess 52 ′, and then the bottom 60 The lower opening is pushed into the inside of the outer barrel 40 and positioned against the bending recess 52; then the barrel groove 51 of the joint 50 is bent inward together with the walls of the inner and outer barrel 40 Until it reaches the bottom surface of the bottom 60; the outer cylinder 40, the joint 50 and the bottom 60 are firmly combined. The structure different from the conventional example is that a metal plate 70 is combined on the top surface of the bottom of the embodiment. Please refer to the third and fourth figures for cooperation. The circular flat part 7 can be affixed to the top surface of the bottom ⑼: the lock it is then locked by the locking member 72 (for example, can be Ding or screws), the metal plate body and the side wall 73 The top edge of the side wall is shown with a side wall protruding upward), the side of the side wall 73 is slightly inclined, and the pushing edge 731 (as shown in the third figure can strengthen the strength of the side wall 73 itself). For those who have bump-like reinforcement to help 732, the metal plate body 70 can be heavy Λ ^ As mentioned earlier, the bottom 6G is on the top surface of the bottom 6G, so when the body 70 is of course, it will also enter: ^ 1! When inside the layer cylinder 40, the inner layer cylinder 80 of the metal plate is inserted into the inside of the layer cylinder 40, and then, the pushing and edge of the top edge of the side wall 7 of the inner layer cylinder can be held. At 731, the inner cylinder 80 f presses the pushing edge 731 into place, and then pushes it from the upper side. In relative terms, the inner wall of the bottom edge gradually snaps down along the side wall 73, because The side wall The m wall 73 gradually enters the bottom edge of the inner cylinder 80, and has a reinforcing rib 732, so that the combination of the two can be more solid. M264233 cannot be disengaged. At this time, the second figure is formed. The structure of the inner and outer double-layer paper tube shown from the original design of the inner and outer double-layer paper tube can provide more applicable uses. The chain 7 can be shown in the fifth figure, inside and outside the inner space defined by the inner and outer double layers; Store different items or materials' In the future, you only need to pull out the inner tube body, and the two materials can be quickly mixed and operated for the convenience. Also as in the first series, the inner tube body 80 can be used as a The aid of the red seven a rolls has the same coaxial function for winding linear items, and the outer cylinder 40 is a wall covering these linear items. It depends on the user's needs. From the above explanation, it can be known that 'this creation has been provided-a kind of structural composition' can be used to define the inner and outer double-layer paper tube inside the paper tube. The applicability of rose is more extensive than that of single-layer paper tube, and it can be used ^ For use, of. Also 'this creation is on the top of the bottom 60 and more Lock two: Hu Zhizhao's work has the effect of strengthening the strength of the bottom 60. ~ Metal plate 70. In summary, this creative shot has reached the expected time in the past or in the open literature, when it has fully met the axis Powerful, and unreliable, 'converting to a new patent in the law, please be grateful for it, and it is worth it = and practical i M264233 [Schematic description] The first figure is a side view of a conventional example The figure is a schematic side sectional view of this creative embodiment.
