成しているので、その強度に限界があった。このように
強度に限界があるので、重量のかさむホースなどの連続

き取るときなどは、紙筒ａが変形してしまうことがあっ
た。The paper cylinder a of the conventional paper reel described above is limited in its strength because the paper cylinder a is formed by only one single-faced corrugated board sheet. Since the strength is limited as described above, the paper tube a may be deformed when winding a heavy continuous body such as a hose or when winding a long continuous body having a large total weight. .
【０００８】また、連続体を巻き取る過程で、それが引

の時には一つひとつの連続体の重量が大きくなっている
ので、下の方のリールが変形することなどもあった。Further, when the continuous body is caught in the process of winding, a very large force acts on the paper tube a, but if the paper tube a is not strong enough, it will be deformed. There were things. Furthermore, in many cases, a plurality of paper reels wound with a continuous body are stacked and transported, but at that time, since the weight of each continuous body is large, the lower reel may be deformed. .

まうという問題があった。In any case, when the paper tube a is deformed, various problems occur. For example, if the paper tube a is deformed while the continuous body is wound, the wound continuous body may collapse. Further, if the paper tube a is deformed in the winding process, the continuous body cannot be properly wound. On the other hand, when the paper cylinder a is deformed as described above, another problem that the paper cylinder a is easily separated from the flanges 1 and 2 occurs. For example, when the paper tube a is deformed, the external force may be concentrated on the deformed portion, and the concentrated external force acts as a strong peeling force on the portion bonded to the flange. Thus, when a peeling force locally acts on the adhesion between the flanges 1 and 2 and the paper tube a, the flanges 1 and 2 cause the paper tube a to move.
Is easy to peel off. If the flanges 1 and 2 were peeled off from the paper tube a, there was a problem that the wound continuous body would come off from the reel.

外筒１１が形成される。FIG. 2 shows the outer strip 13 made of a single-faced corrugated cardboard sheet forming the outer cylinder 11. A fitting convex portion 14 is formed on one end side of the outer band 13 and a fitting concave portion 15 is formed on the other end side thereof. The fitting convex portion 14 and the fitting concave portion 15 are formed when they are fitted to each other. The shape is exactly the same. By fitting the above-mentioned fitting convex portion 14 and concave portion 15 to each other, the outer band-shaped body 13 continues in a tubular shape, but by bonding the fitting portion with the adhesive paper 16,
The outer cylinder 11 is formed.

同様である。As described above, since the convex portion 14 and the concave portion 15 are shaped so as to be exactly coincident with each other, when they are fitted together, no step is formed in the fitted portion. Moreover, the adhesive paper 16 is attached to the fitting portion.
Since it suffices to attach only, the outer cylinder 11 as a whole has almost no step. Further, as in the illustrated embodiment, if the tip end side of the convex portion 14 is in an enlarged shape and the opening portion of the concave portion 15 is in a reduced shape, when they are fitted together,
It becomes difficult to pull out in the pulling direction. It should be noted that, as in the conventional example, the insertion protrusions 4a to 4d and 5a to 5d are formed at equal intervals on both sides of the outer band 13 in the longitudinal direction.

実施態様では、このような複雑な作業が必要ない。In addition, the fitting convex portion 14 and the fitting concave portion 15 are fitted to each other, and the adhesive paper 16 is simply stuck.
Since the outer cylinder 11 can be formed, the outer cylinder 11 can be easily formed. For example, in the conventional case, the flat paper and the corrugated paper at one end of the strip are peeled off,
Since the other end portion is sandwiched between the stripped flat paper and the corrugated paper and the flat papers are adhered to each other, the adhering work is complicated. However, this embodiment does not require such complicated work.

て筒状に丸める。The outer tube 11 is formed by the outer band 13 as described above. The inner band 12 formed by rolling a band-shaped single-faced corrugated cardboard sheet into a tube is inside the outer tube 11 thus formed. Insert. The length of the inner strip 12 in the longitudinal direction is the outer strip 13 forming the outer cylinder 11.
It is designed to be slightly shorter than the length of. The width H2 of the inner strip 12 is the width H of the outer cylinder 11.
It is almost equal to 1. Here, the width H of the outer cylinder 11
As shown in FIG. 3, 1 means the distance from the root of the insertion protrusions 4a to 4d to the root of the insertion protrusions 5a to 5d. When the inner strip 12 is inserted into the outer cylinder 11, the corrugated paper of the inner strip 12 is rolled inward and the flat paper is turned outward.

管理を厳密にする必要がない。Then, as shown in FIG. 3, the rolled inner strip 12 is inserted into the outer cylinder 11. When the inner strip 12 is thus inserted inside the outer tube 11, the inner strip 12 expands so as to increase its diameter by its own restoring force. At this time, the inner strip 12 expands with the flat paper side along the inner side of the outer cylinder 11. In this way, by simply rolling the inner strip 12 and inserting it inside the outer tube 11, the inner strip 12 comes into close contact with the inner side of the outer tube 11, so that In order to bring the inner strips 12 into contact with each other, it is not necessary to strictly control the dimensions of the inner strips 12.

If the positions of the flat paper and the corrugated paper of the inner band 12 are reversed so that the corrugated paper faces outward, the corrugated paper comes into contact with the inner side of the outer cylinder 11. When the corrugated paper of the inner strip 12 contacts the inner side of the outer cylinder 11, the inner strip 12 is placed between the corrugated paper of the outer cylinder 11.
The inner corrugated paper 12 is not spread well due to the corrugated paper. However, as described above, by bringing the flat paper of the inner strip 12 into contact with the inner side of the outer cylinder 11,
The inner strip 12 can be expanded smoothly.

Since the width H1 of 1 is substantially the same, the outer cylinder 11
As shown in FIG. 1, the inner strip 12 that extends along the inside of the inner strip 12 has the edge of the inner strip 12 and the edge of the outer cylinder 11 aligned with each other. When the edges of the inner strip 12 and the outer cylinder 11 are aligned with each other, the flanges 1 and 2 are fixed to the both ends to complete the paper reel. At that time, as shown in FIG. The outer cylinder 11 is dipped in the paste 18 of the paste container 17 with the inside attached. At this time, all of the insertion protrusions 4a to 4d and 5a to 5d of the outer cylinder 11 are immersed in the glue 18, but the other edge portions are made to touch the glue 18. When the edge portion of the outer cylinder 11 is soaked to the extent that it touches the glue 18, the edge of the inner strip 12 that matches this edge also touches the glue 18.

取ることができる。According to the above embodiment, the cylindrical portion 10
Is formed by the outer cylinder 11 and the inner strip 12 provided inside the outer cylinder 11, the strength of the tubular portion 10 is stronger than that of the conventional one by the amount of the inner strip. Moreover, since the inner strip 12 comes into close contact with the inside of the outer cylinder 11, the cylindrical portion 10
The strength of can be maintained. Therefore, even if a strong external force acts on the cylindrical portion 10, it does not deform. Since the tubular portion 10 is not deformed, the continuous body wound around the tubular portion 10 does not collapse. Moreover, since the tubular portion 10 is not deformed, the continuous body can be successfully wound up.

ようになる。Further, in the above embodiment, the inner strip 1 is formed.
The length 2 is shorter than the length of the band-shaped body forming the outer cylinder. However, if the length is made several times longer than the length of the band-shaped body, the strength can be maintained. . For example, the length of the inner strip is made many times longer than that of the strip, and the strip is rolled into a spiral shape and inserted into the outer cylinder. In this way, when the long inner strip is rolled into a spiral shape and inserted into the outer cylinder, the inner strip expands in multiple circles. As the number of inner strips increases in this way, the strength of the tubular portion increases accordingly. Moreover, as the number of windings of the inner strip 12 increases, the restoring force on the outer side increases. Therefore, the outer surface of the inner strip comes into closer contact with the inner side of the outer cylinder.

業が容易になる。In this embodiment, a single-faced cardboard sheet is used as the cardboard sheet for forming the outer cylinder or the inner strip, but a double-faced cardboard sheet may be used. By using the double-sided corrugated sheet,
It is possible to make a stronger paper reel. However, when the corrugated board sheet is rolled into a tubular shape, the one-sided corrugated board sheet is easier to roll, and the work for making the tubular shape is easier.

れにくくなる。According to the first aspect of the present invention, the cylindrical portion includes the outer cylinder,
Since the inner band-shaped body is provided inside the outer cylinder, the inner band-shaped body is brought into contact with the inner side of the outer cylinder, and the edges of the outer cylinder and the inner band-shaped body are bonded to the flange. , The strength of the tube becomes stronger. Therefore,
Even if a strong external force acts on this cylindrical portion, it will not be deformed.
Further, since the tubular portion does not deform, the tubular portion does not easily come off from the flange. Moreover, since both the outer cylinder and the inner strip are adhered to the flange, the adhesive force between the flange and the cylinder is increased, and the cylinder is more unlikely to come off from the flange.

く抑えることができる。According to the third aspect of the present invention, the outer cylinder is formed by the belt-shaped corrugated cardboard sheet, and the inner belt-shaped body made of the face corrugated cardboard sheet and having the substantially same width as the outer cylinder is inserted inside the outer cylinder. Since the edges of the outer cylinder and the inner strip are aligned and the edges of the outer sleeve and the inner strip are attached to the glue, the flange of the outer sleeve and the edge of the inner strip are bonded to each other. The strength of the part can be increased. Therefore, even if a strong external force acts on this cylindrical portion, it does not deform. Further, since the tubular portion does not deform, the tubular portion does not easily come off from the flange. Moreover, since both the outer cylinder and the inner strip are adhered to the flange, the adhesive force between the flange and the cylinder is increased, and the cylinder is more unlikely to come off from the flange. Furthermore, the inner strip can be brought into contact with the inner side of the outer cylinder only by inserting the inner strip into the outer cylinder. Further, without strict dimensional control of the inner strip, the outer cylinder and the inner strip come into contact with each other, so that the cost can be kept low.
