DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the duvet of the present invention, FIGS.
(A) A partition cloth 1 having a structure as shown in (b) is used. As the partition cloth 1, it is preferable to use the band-shaped cloth 2 as one component and use a nonwoven fabric or the like so as to facilitate flat folding as described later. This band-like cloth 2
As shown in FIGS. 4, 5 and 6 (a) and 6 (b), a plurality of holes 3 formed at predetermined intervals in the length direction, and ear portions 4 formed by bending both side edges along the length direction. And a rectangular partition wall portion 5 formed so as to be able to be bent along a substantially middle portion between the two ear portions 4. The above-mentioned hole 3 can have various other shapes such as an elliptical shape and a circular shape.

As shown in FIG. 7A, for example, as shown in FIG. 7 (a), the partition cloth 1 has a plurality of strip-shaped cloths 2 having a length corresponding to the size of the front side ground and the back side ground. [Indicated by a dashed line] is used. The arrangement pattern of the band-shaped cloth 2 is not limited to the pattern shown in FIG. 7A, and a plurality of band-shaped cloths 2 may be arranged in parallel as shown in FIG. 7B or FIG. Arrays are also possible.

As shown in FIG. 1, the duvet 10 of the present invention has the above-described partition cloth 1 interposed between the front side ground 11 and the back side ground 12, and the ears 4 formed on both side edges of the band-shaped cloth 2. Then, the inner surfaces of the front side ground 11 and the back side ground 12 and the ear portions 4 of the crossing portions of the belt-like cloth 2 are joined by thermocompression bonding. In addition, the periphery of the front side ground 11 and the back side ground 12 are sealed to form a bag 13, whereby a large number of compartments 14 are formed between the front side ground 11 and the back side ground 12 by the partition cloth 1. . The compartments 14 communicate with each other via the holes 3 in the band-shaped cloth 2 of the partition cloth 1. All the compartments 14 communicating through the holes 3 of the partition cloth 1 are filled with feathers (not shown).

When fabricating the duvet 10 of the present invention, as shown in FIG. 8, the partition cloth 1 having the above-mentioned strip cloth 2 interposed therebetween is interposed between the front side ground 11 and the back side ground 12, Front side ground 11 and back side ground 12 using a thermocompression bonding machine
From the outside, the ears 4 bent at the inner surfaces of the front side ground 11 and the back side ground 12 and both side edges of the strip cloth 2 of the partition cloth 1, and the ear parts 4 of the strip cloth 2 intersecting with each other of the partition cloth 1 are heated. Join by crimping. At this time, since the partition 5 located between the ears 4 of the partition cloth 1 is formed so as to be able to be bent along substantially the middle thereof, the partition 5 is flattened by pressing from the outside of the front side ground 11 and the back side ground 12. Therefore, thermocompression bonding between the front side ground 11 and the back side ground 12 and the ears 4 of the partition wall cloth 1 can be easily performed.

The bonding by thermocompression bonding may be performed, for example, in the following manner. A thermosetting or heat-softening adhesive is used, and the above-mentioned adhesive (not shown) is previously applied (coated) or impregnated to the ears 4 of the partition wall cloth 1.
The ears 4 of the partition wall cloth 1 are brought into contact with the front side ground 11 and the back side ground 12 and are bonded by the above-mentioned thermocompression bonding with an adhesive. Incidentally, as the adhesive, a hot-melt type tape-shaped adhesive can be used.

In this manner, the front side ground 11 and the back side ground 12
Is joined to the ears 4 of the partition cloth 1 and the peripheral edges of the front side ground 11 and the back side ground 12 are sealed to form the bag 13. Thereby, inside the bag body 13, the front side ground 11
Partitioning cloth 1 between the backing material 12 and the
Is formed (see FIG. 9). However, each of the compartments 14 is in a state where the strip cloths 2 of the partition wall cloth 1 communicate with each other at the portions where they cross each other.

Therefore, when forming the bag body 13 by sealing the peripheral edges of the front side ground 11 and the back side ground 12, an unsealed portion (not shown) is formed on a part of the peripheral edge of the front side ground 11 and the back side ground 12. Is formed, and feathers are injected from the unsealed portion by an appropriate means. By the injection of the feathers, all the compartments 14 communicating with each other through the holes 3 formed at the portions of the partition cloth 1 that intersect each other are filled with the feathers inside the bag 13. Thereafter, the unsealed portion is sealed by an appropriate means, whereby the production of the duvet 10 is completed.

[0015]

According to the present invention, a plurality of holes formed at predetermined intervals in the length direction, an ear formed by bending both side edges along the length, and a gap between the two ears are formed. Using a partition cloth, which is arranged by crossing a plurality of band-shaped cloths each including a partition part formed so as to be able to bend substantially along the middle at a portion where a hole is formed, and using the partition cloth with a front side ground and a back side ground By interposing them between them and joining them together by thermocompression bonding to form a large number of compartments, there is no need to sew the front side ground and the back side ground, only the thermocompression bonding from the outside of the front side ground and the back side ground . Since a large number of compartments, each of which is filled with feathers, can be easily and quickly formed by simple means, the number of steps and manufacturing costs can be reduced, and an inexpensive duvet can be provided.

Further, in the partition cloth, since the partition located between the front side and the back side is formed to be bendable, the partition is bent and flattened at the time of thermocompression bonding. In addition, thermocompression bonding between the back side material and the ears of the partition wall cloth can be easily and reliably performed. In addition, since the partition wall cloth is formed with holes communicating with all the adjacent compartments, the filling of the feathers into each compartment can be performed easily and promptly. In this way, manufacturing operations such as thermocompression bonding between the front and back sides and the partition wall cloth and filling of the inside with feathers can be performed easily and quickly, and are of great practical value.

Furthermore, since the seams (perforations) do not appear on the outer surface of the futon, a good appearance can be obtained, and there is no needle hole on the outer surface of the front side and the back side. Even if it is provided, insects such as mites do not enter the futon, which is preferable in health and hygiene. Also, on the outer surface of the futon, the tip of the feather does not protrude from the needle hole, so that the futon feels good and does not cause physiological discomfort, so that it can be used comfortably for a long period of time.
