In FIG. 1, reference numeral 1 denotes a single sheet 3 cut into a predetermined shape as shown in FIG. 3 is a case main body of a fishing rod case 5 formed by bending in a cylindrical shape so that the left and right sheet end portions 3a and 3b abut each other, and the sheet 3 is a synthetic resin such as polyurethane, ethylene vinyl acetate, or a thermoplastic resin. An outer cloth 7 and an inner cloth 9 as thin decorative cloths made of synthetic resin such as nylon or polypropylene are attached to the front and back of the sheet 3. Yes.

  As shown in FIG. 2, the bottom portion of the case body 1 is inserted into a bottom cup 11 having a substantially U-shaped cross section formed of a synthetic resin having a rigidity higher than that of the case body 1. It is sewn with a thread so as to form a cylinder along. Then, as shown in FIG. 3, a portion between the sheet end portions 3 a and 3 b abutted together is a fishing rod inlet / outlet port 15 of the case body 1, and the fishing rod inlet / outlet port 15 is connected to the bottom cup 11 from the top of the case body 1. A slide fastener 17 that opens and closes is sewn between the sheet end portions 3a and 3b.

As shown in FIG. 1, a shoulder belt 19 and a handle 21 are attached to the back of the case body 1, and a side pocket 23 for small items is attached to one side surface of the case body 1.
As shown in FIGS. 2 and 3, the entire surface on the inner surface side of the foamed sheet 3 is provided with a melt-curing portion 25 that is a portion cured by being heated and melted by a heat source. The form is characterized in that the shape of the case main body 1 is maintained by this melt-cured portion 25 provided by melting and curing the inner surface side of the sheet 3 instead of the conventional hard sheet plate.

The fishing rod case 5 according to the present embodiment is configured as described above, and the fishing rod case 5 is manufactured as follows by the first embodiment of the manufacturing method according to claims 4 and 5.
First, as shown in FIG. 2, one sheet 3 of foam material is cut into a predetermined shape capable of forming the case body 1.
Then, as shown in FIG. 4, the cut sheet 3 is spread and placed on a flat table 27, and the nozzle 29 is arranged away from the sheet 3. Thereafter, as shown in the drawing, the nozzle 29 is moved in the left-right direction (in the direction of the left and right sheet end portions 3a, 3b), and hot air W (or flame) is blown from the nozzle 29 over the entire upper surface to move downward from above the sheet 3. The melted and hardened portion 25 is formed on the entire upper surface by being melted sequentially and cured by stopping the cooling or blowing of hot air W and leaving it to stand.

Thus, when the melt-cured portion 25 is provided by melting and curing the entire upper surface of the sheet 3 in this way, the composition on the melt-cured portion 25 side becomes dense and shrinks. The entire sheet 3 is curled and brazed from the left and right directions inward.

Thus, according to the fishing rod case 5 manufactured in this manner, the melt-hardened portion 25 attempts to maintain the shape of the case main body 1 so that the case main body 1 is not easily crushed, and the fishing rod case 5 collides with a corner of a rocky place. When the sheet is made to fall or collide with the ground, the foam sheet 3 absorbs the impact and prevents the fishing rod from being damaged.
Moreover, the case main body 1 (sheet | seat 3) will be in the state bent to the inner periphery (inner cloth 9 side) entirely by fixing the bottom part of the sheet | seat 3 to the cylinder shape along the peripheral part 13 of the bottom cup 11. FIG. In addition, since the sheet 3 is provided with the melt-curing portion 25, the case body 1 is brazed with the sheet 3 curled inward with the melt-curing portion 25 inside as shown in FIG. Therefore, the case body 1 is maintained in a shape bent to the inner circumference which is convenient for the case body 1 to be cylindrical.

  Therefore, even if the slide fastener 17 is lowered from the top of the case body 1 to the bottom cup 11 to open and close the fishing rod outlet 15 to open and close the fishing rod, the case body 1 expands due to the elasticity of the foam sheet 3 and the fishing rod is removed. The mouth 15 does not open greatly, and therefore, when the fishing rod outlet 15 is closed with the slide fastener 17 after the fishing rod is taken in and out, the slide fastener 17 can be easily operated.

However, instead of the conventional heavy hard sheet plate, the shape of the case main body 1 is maintained by the melt-curing portion 25. As a result, the conventional sheet plate is no longer needed and the fishing rod case 5 is lightened. Is planned.
And according to the manufacturing method of the fishing rod case 5 which concerns on this embodiment, the hot air W is blown from the nozzle 29 over the whole upper surface of the sheet | seat 3 as above-mentioned, and it is made to melt and harden | cure the shape of the case main body 1 The melt-cured portion 25 can be easily formed, and the sheet 3 is curled inward by forming the melt-cured portion 25, so that the bottom of the sheet 3 is attached to the peripheral portion 13 of the bottom cup 11. It becomes easy to do the work when it is fixed along the cylinder.

As described above, according to the fishing rod case 5 according to the present embodiment, the shape of the case main body 1 is maintained by the melt-curing portion 25 instead of the conventional hard sheet plate, so that the conventional sheet plate is not required and the fishing rod case is used. 5 was reduced in weight, and it was also difficult to be crushed and excellent in impact resistance.
In this way, since the conventional sheet plate is not required, the cost can be reduced.
Furthermore, according to the present embodiment, since the sheet 3 is curled inward by being provided with the melt-curing portion 25 on the entire inner surface side of the sheet 3, the slide fastener 17 is moved from the top of the case body 1 to the bottom cup. Even if it is lowered to 11 and the fishing rod outlet 15 is opened, the case main body 1 does not expand due to the elasticity of the foamed sheet 3 and the fishing rod outlet 15 is not greatly opened. In closing, the slide fastener 17 can be easily operated.

  Then, according to the method for manufacturing a fishing rod case described above, the work of winding a sheet of foam material around the outer periphery of the rigid sheet plate while holding the rigid sheet plate in the conventional manner becomes unnecessary. Since the seat 3 is rolled inward with the 25 facing inward, the subsequent manufacturing work of the fishing rod case 5 such as attachment to the bottom cup 11 is facilitated, and the fishing rod case is lightweight, hardly crushed and has excellent impact resistance. 5 was easily manufactured.

Further, since the nozzle 29 is separated from the sheet 3 when forming the melt-cured portion 25, the melted sheet 3 does not adhere to the nozzle 29 and has an advantage of excellent workability.
As a method for forming the melt-cured portion 25, instead of the method using the nozzle 29 described above, as shown in FIGS. 6 and 7, the concave portion 33 of the base 35 in which a concave portion 33 having a circular arc cross section is provided in the upper portion 31 in the longitudinal direction. 33, the sheet 3 is placed, the mold 37 formed in the same shape as the upper part 31 of the base 35 is heated to bring it close to the sheet 3, and while being separated from the sheet 3, the upper surface is melted and cured. Alternatively, as shown in FIG. 7, the sheet 3 is curled and brazed inward with the melt-cured portion 25 inside.

Therefore, this method also facilitates the subsequent manufacture of the fishing rod case such as attachment to the bottom cup 11 as in the manufacturing method described above, and the fishing rod case can be easily manufactured. Since the heated mold 37 is separated from the sheet 3 in forming, the melted sheet 3 does not adhere to the mold 37 and has an advantage of excellent workability.
FIGS. 8 to 12 show a fishing rod case according to the second embodiment of claims 1 to 3. In this embodiment, three belt-like melt-cured portions 39 are provided on the inner surface side of the sheet 3 as shown in FIG. By providing in the longitudinal direction of the sheet 3 (longitudinal direction of the case main body 41 to be formed), the sheet 3 is brazed so as to be bent inwardly in a cylindrical shape as shown in FIGS. The shape of the case main body 41 is maintained by the curing unit 39.

In the present embodiment, the three melt-cured portions 39 are provided on the inner surface side of the sheet 3, but the number of the melt-cured portions 39 is not limited to three.
Moreover, since the other structure of the fishing rod case 43 which concerns on this embodiment is the same as that of the fishing rod case 5 of FIG. 1, the same code | symbol is attached | subjected to the same thing and those description is abbreviate | omitted.
Thus, the fishing rod case 43 according to this embodiment is manufactured as follows by the third embodiment of the manufacturing method according to claims 4 and 5.

First, as shown in FIG. 8, one sheet 3 of foam material is cut into a predetermined shape capable of forming the case main body 41.
Then, as shown in FIG. 10, the cut sheet 3 is spread and placed on a flat table 27, and the three nozzles 29 that respectively form the three melt-cured portions 39 described above are arranged apart from the sheet 3.

Thereafter, while moving the three nozzles 29 in the longitudinal direction of the sheet 3, hot air W (or flame) is blown from the nozzle 29 onto the upper surface of the sheet 3 to melt the sheet 3, and the sheet 3 is cured to be belt-shaped. The melt-cured portion 39 is formed in the longitudinal direction of the sheet 3.
Thus, when the melt-cured portion 39 is provided by melting and curing the upper surface of the sheet 3 in this way, the composition of each melt-cured portion 39 becomes dense and shrinks as shown in FIGS. Therefore, these grooves 45 braze the sheet 3 so that it can be bent inward.

  Thereafter, the outer cloth 7 and the inner cloth 9 are attached to the front and back of the sheet 3, the slide fastener 17 is sewn between the sheet end portions 3a and 3b, and then the sheet 3 is attached to the outer cloth as shown in FIG. 7. Bend along with the inner cloth 9 in the direction of the arrow, and insert the bottom into the bottom cup 11, then sew on the peripheral wall 13 of the bottom cup 11 with a thread, the shoulder belt 19, the handle 21, and the side for small items A fishing rod case 43 is manufactured by attaching the pocket 23 and the like to the case body 41.

Thus, even with the fishing rod case 43 manufactured in this manner, the melt-hardened portion 39 maintains the shape of the case main body 41 so that the case main body 41 is not easily crushed, and the fishing rod case 43 collides with a corner of a rocky place. When it is dropped and collided with the ground, the foam sheet 3 absorbs the impact and prevents the fishing rod from being damaged.
Moreover, the case main body 41 (sheet | seat 3) will be in the state bent to the inner periphery (inner cloth 9 side) entirely by fixing the bottom part of the sheet | seat 3 to the cylinder shape along the peripheral part 13 of the bottom cup 11. FIG. In addition, since the melt-hardened portion 39 is provided in the sheet 3 and the groove 45 is provided, the groove 45 brazes the sheet 3 so that it can be bent inward as shown in FIG. The shape bent to a predetermined inner circumference that is convenient for the case main body 41 to be cylindrical is maintained.

  Therefore, even if the slide fastener 17 is lowered from the top of the case body 41 to the bottom cup 11 and the fishing rod outlet 15 is opened in order to insert and remove the fishing rod, the case body 41 expands due to the elasticity of the foamed sheet 3, and the fishing rod is removed. The mouth 15 is not greatly opened, and therefore, the slide fastener 17 can be easily operated when the fishing rod outlet 15 is closed with the slide fastener 17 after the fishing rod is taken in and out.

However, instead of the conventional heavy hard sheet plate, the shape and shape of the case main body 41 is maintained by the melt-curing portion 39, so that the conventional sheet plate is not required and the fishing rod case 43 can be reduced in weight.
And according to the manufacturing method of the fishing rod case 43 which concerns on this embodiment, the hot air W is sprayed and melted from the three nozzles 29 on the upper surface of the sheet | seat 3, and the shape of the case main body 41 is hold | maintained by hardening this. The three belt-shaped melt-cured portions 39 can be easily formed, and the sheet 3 is brazed so as to be bent inward by forming the melt-cured portions 39, so that the bottom of the sheet 3 is attached to the bottom cup 11. The operation is facilitated when the cylinder is fixed along the peripheral edge portion 13.

As described above, according to the fishing rod case 43 according to the present embodiment, the shape of the case main body 41 is maintained by the melt-curing portion 39 instead of the conventional hard sheet plate. 43 can be reduced in weight, and it is difficult to be crushed and has excellent impact resistance.
In addition, since the conventional hard sheet plate is not required, the cost can be reduced.

  Further, in the present embodiment, since the three melt-cured portions 39 are provided on the inner surface side of the sheet 3 so that the sheet 3 can be bent inwardly, the slide fastener 17 is attached to the top of the case body 1. When the fishing rod outlet 15 is opened from the bottom cup 11 to open the fishing rod outlet 15, the case main body 41 is not expanded by the elasticity of the foam sheet 3, and the fishing rod outlet 15 is not greatly opened. When closing, there is an advantage that the slide fastener 17 can be easily operated.

  Then, according to the method for manufacturing a fishing rod case described above, the work of winding a sheet of foam material around the outer periphery of the rigid sheet plate while holding the rigid sheet plate in the conventional manner becomes unnecessary. By providing the groove 39 and the groove 45, the seat 3 is brazed so as to be bent inward as shown in FIG. 11. Therefore, the subsequent manufacturing operation of the fishing rod case 43 such as attachment to the tom cup 11 becomes easy. The fishing rod case 5 that is lightweight, hardly crushed, and excellent in impact resistance can be easily manufactured.

Further, in the present embodiment, since the nozzle 29 is separated from the sheet 3 when forming the melt-cured portion 39, the melted sheet 3 does not adhere to the nozzle 29 and has an advantage of excellent workability.
In each of the above-described embodiments, the melt-curing portions 25 and 39 are provided on the inner surface side of the sheet 3.
