Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a bag for futon fabric and a method for filling the bag with filler, and more specifically, to interposing an interlining between the front and back side fabrics. A bag for futon fabric in which a plurality of compartments are formed between the side fabric and the inner fabric by alternately attaching predetermined positions of the core fabric to the front and back side fabrics, and the futon fabric used to manufacture the futon. The present invention relates to a filling method for filling a ground bag with filler such as feathers.

(Prior art and problems to be solved by the invention) The applicant has proposed the following as prior art to the present invention:
Patent Application No. 59-277848 (Japanese Patent Application No. 154618-1983)
has made an invention related to.

That is, as shown in FIG. 11A, this invention interposes a core material 2c between the front and back side materials 1c and 1d, and alternately inserts the core material 2c at predetermined intervals on both side materials 1c and 1d, respectively. A large number of compartments 5 are fixed to the
c, ..., and interpose a plurality of partition pieces 3c, ... in advance between the side fabrics 1c, 1d and the core material 2c in the direction intersecting the compartment 5c, as shown in FIG. 3d is fixed to the batting material to form a bag for futon fabric, and then filler such as feathers 4c is placed in the compartment 5c of the bag for futon fabric using a pipe-shaped filling tool as shown in Fig. 7C. 13c, and then the partition piece 3
By fixing the other end 3e of c to both sides 1c and 1d by heat fusing or the like, subdivided chambers 12c are formed as shown in Fig. 7D, thereby producing a futon divided vertically and horizontally. It is something that

However, in the above invention, the other end 3e of the partition piece 3 must be heated and fused to both sides 1c and 1d after being filled with the filler, that is, in a state where the filler is filled. The welding work is troublesome and the workability is unstable, and there is a risk that a filler may be interposed between the side fabrics 1c, 1d to be welded and the other end 3e of the partition piece 3c, resulting in poor welding condition. There was a problem that there was.

That is, the other end 3e of the partition piece 3c is connected to the side area 1c,
Although it is originally preferable to form subdivided chambers in the futon fabric bag before filling with the filler by fixing the filler to the filler 1d in advance, in this case, the filling device 13c cannot be inserted into each subdivided chamber. Previously, the other end 3e of the partition piece 3c was left in a free state, and it was necessary to carry out work such as heating and fusing the partition piece and the side fabric after filling the filling material.

On the other hand, a filling method and a bag for futon fabric in which the filler can be inserted into each subdivided chamber by inserting a filling tool after forming the bag for futon fabric are disclosed in, for example, Japanese Patent Application Laid-Open No. 58-218919. There is an invention published in the No.

That is, as shown in FIG. 10, in this invention, a T-shaped gusset piece 20 is formed in the partitioning portion of each sub-chamber, an opening 21 is formed in the gusset piece 20, and the opening 21 is The filling tool is inserted into each sub-divided chamber 22 through the opening.

However, such bags for futon fabrics have had the following problems.

(a) In other words, since the opening 21 of the gusset piece 20 as described above is formed in the same line as the section of the sub-divided chamber 22 formed by the gusset piece 20, the When handling futons, that is, when folding them, hanging them to dry, etc., if the futon is tilted, the filling will become uneven as shown in Figure 10 (c) in any one sub-divided room. There is a possibility that the filling may move from one sub-divided chamber 22 to the adjacent sub-divided chamber 22 through the opening 21, and as a result, the amount of the filled material may vary in each sub-divided chamber 22. There was a problem in that the filling material was uneven throughout the futon.

Particularly, when air pressure is generated in the subdivided room due to compression caused by folding a futon, etc., this movement of the filling becomes more likely.

However, in this futon bag, the construction is such that no gaps are formed at the four corners of the sub-divided chamber 22, so the above air pressure is likely to be generated, and once the air pressure is generated, the air pressure is Since the action is concentrated on the openings of the gusset pieces, there is an extremely high probability that the filling will move.

(b) Furthermore, since the openings 21 of the gusset pieces 20 are formed in the same line as the partitions of the sub-divided chambers 22, the filler can be inserted from the openings at both ends of the futon to open the openings of the gusset pieces 20. 21, the filling tool may not be reliably guided and may shift from side to side.
It is not easy to search for the opening 21 in itself, and as a result, filling the adjacent sub-chambers with filler is extremely complicated, resulting in a significant drop in work efficiency.

(c) Furthermore, does the bag for futon fabric like the one above have gussets at each boundary of each subdivision room? Since the sewing work is performed by disposing the sewing machine, there is a problem that the sewing work becomes extremely complicated.

The present invention has been made to solve all of the above-mentioned problems, and it eliminates the need for work such as heating and fusing the partition pieces and the side fabric after filling with the filling material, and furthermore, The purpose of this is to prevent the filling material from moving unintentionally and to facilitate the insertion of the filling tool into each sub-chamber.

(Means for Solving the Problems) The present invention has been made as a bag for futon fabric and a method for filling the bag with a filler in order to solve the above problems in order to achieve the above object. ,
The features of the bag for futon fabric are the front and back side fabrics 1a,
A core material 2 is interposed between 1b and the side material 1
A, 1b and the core material 2 are interposed with a plurality of partition pieces 3, . The pieces 3 are attached alternately to the front and back sides 1a, 1b, respectively, to form a large number of compartments 5, which can be filled with filler such as feathers, between the sides 1a, 1b and the interlining 2. By attaching both ends 3a and 3b of the partition piece 3 in the direction intersecting with the partition piece 5 to the core material 2 and the side materials 1a and 1b, respectively, the partition chamber 5 is divided and a large number of sub-divided chambers 12 are formed vertically and horizontally. , and a normal passage 14, into which a filling tool 13 for filling the filling material can be inserted, is formed along the longitudinal direction of the compartment 5 by an elongated sheet material, and the passage 14 is used for filling the filling material. The passageway 14 is connected to the sub-chamber 12 through the opening 16, and the entrance portion 17 of the passage 14 is located near the opening 8 of the compartment 5 to the extent that the filling tool 13 can be easily inserted. and the filling port 16 is formed at a position spaced a predetermined distance from the partition piece 3 to the extent that movement of the filling between adjacent sub-chambers 12, 12 cannot occur through the filling port 16. It's about being done.

The method for filling the bag with the filling material is characterized in that after the bag is formed as described above, the filling tool is inserted into the passage of each compartment, and the tip of the filling tool is inserted into the filling port. The filling material is discharged into the sub-divided chambers and sequentially filled into each sub-divided chamber.

(Function) In other words, since a passage communicating with the sub-divided chambers through the filling port is provided in the longitudinal direction of each compartment, both ends of the compartment pieces are fixed to the core material and side material before filling with the filling material. Even though the futon bag is divided vertically and horizontally, the filling tool is inserted into the passage as described above, and the tip of the filling tool is exposed from the filling opening into the subdivided chamber, or the filling tool is inserted into the compartment. By allowing the tip of the filling tool to emerge into the sub-divided chambers from the openings at both ends, it becomes possible to fill all the sub-divided chambers with the filling material.

Furthermore, since the futon fabric bag is divided vertically and horizontally, the movement of the filling within the compartment is prevented, and the filling is not biased in either the vertical or horizontal directions.

In particular, the passage is formed of an elongated sheet material, and the filling port 16 is formed to such an extent that movement of the filling between adjacent sub-chambers 12, 12 cannot occur through the filling port 16. is formed at a position spaced apart from the partition piece 3 by a predetermined distance, so that the elongated sheet material is pressed against the filling material and the filling port 16 is closed. No movement of the filling into the chamber 12 occurs.

Further, since the entrance portion 17 of the passage 14 is formed so as to be located near the opening 8 of the compartment 5 to the extent that the filling tool 13 can be easily inserted, the filling tool 13 from the entrance portion 17 is formed close to the opening 8 of the compartment 5. Insertion of the filling tool 13 is very easy, and after insertion, the filling tool 13 is guided by the passage 14 formed of the elongated sheet material, so it is easy to insert the filling tool 13 into the passage 14 and divide it into each subdivision. Insertion into the chamber 12 is very easy.

(Example) Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows a bag for futon fabric as an example, in which A is a plan view, B is an enlarged sectional view of the main part taken along line A-A, and C is an enlarged sectional view taken along line B-B of A, with the middle omitted; D shows an enlarged cross-sectional view of the main part taken along the line CC of A, E shows an enlarged cross-sectional view taken along the D-D line of A, and F shows a schematic plan view of the piece of cloth.

In FIG. 1, 1a and 1b are the front and back side fabrics made of polyamide synthetic fibers, and 2 are the side fabrics 1a and 1.
A core material made of non-woven fabric interposed between b is formed into a net shape with countless small holes (not shown), and one end 2b of the interlining is interposed between the two ends of the front and back side materials 1a and 1b. They are heat fused together and shown in Figure 1A,
As shown in (b), plural locations in the longitudinal direction of the core material 2 are alternately heat-sealed to the front and back side materials 1a, 1b via double-sided heat-sealing tape 6, and the inner material 2 is heat-sealed to the inner materials 1a, 1b and the inner materials 1a, 1b alternately. A total of 5 compartments 5 between the interlining 2,...
is formed. Reference numerals 14, . . . indicate passages for insertion of filling provided along the longitudinal direction of the compartments 5, . . . Both side edges 15a, 1 of the cloth piece 15 made of the same nonwoven fabric as the interlining 2,...
5b to the core material 2 by ultrasonic welding. Reference numerals 3 and 3 denote compartment pieces made of a nonwoven fabric of the same material as the core material 2, whose one ends 3a and 3b are heat-sealed to the core material 2 as shown in FIG. The cloth pieces 15, . It is heat-sealed via heat-sealing tapes 6, 6, and moreover, as shown in FIG.
It is heated and fused between the and the middle interlining 2. This partition piece 3 is attached to the side area 1 as shown by the dotted line in Figure 1A.
A total of four pairs are provided at equal intervals in the lateral direction of a and 1b.

16 are provided at equal intervals on the cloth piece 14 and the centering material 2 on the back side of the cloth piece 14 as shown in FIG. The filling opening formed by the notch is shown in FIG.

Reference numeral 8 indicates an opening formed at one end side of each compartment 5.

Next, a filling method for filling filler such as feathers into the futon fabric bag 9 having such a structure will be described.

First, as shown in FIG. 2, the pipe-shaped filling tool 13 is inserted into the passage 14 from the opening 8 at one end of the compartment 5 and the entrance 17 of the passage 14 until it reaches the innermost part, and then Then, as shown in FIG. 3A, the bent tip 13a of the filling tool 13 is brought out from the filling port 16 on the tip side of the passage 14 into the innermost subdivided chamber 12, and the feathers 4 are removed from the filling tool 13. Divided room 12
After that, the filling tool 13 is removed from the sub-divided chamber 12, and as shown in FIG. Then, the filling tool 13 is brought out and the feathers 4 are blown and filled in the same manner.

In this case, the entrance portion 17 of the passage 14 is
Since it is formed near the opening 8 of the compartment 5, the insertion of the filling tool 13 from the entrance 17 becomes very easy.

Next, in this way, the upper and lower sub-divided chambers 12 at the innermost part
After filling the inside with feathers 4, the filling tool 13 is placed in the sub-divided chamber 12 on the side of the opening 8, and the filling tool 13 is made to come out into each sub-divided chamber 12 from each filling port 16, and the feathers 4 are sequentially filled into each sub-divided chamber 12. Blow in and fill.

In addition, the sub-division chamber 1 closest to the opening 8 of the division chamber 5
The inside of the compartment 2 is filled with feathers 4 directly from the opening 8 of the compartment 5 with the filling tool 13 removed from the passage 14.

Furthermore, all sub-division rooms 12 within each compartment 5
After filling the inside with the feathers 4, the filling tool 13 is similarly inserted into the other compartments 5, and the feathers 4 are filled into the respective sub-divided chambers 12. After all the sub-compartments 12 are filled with down feathers 4, the edges 2a of the openings 8 at both ends are heat-sealed to produce a duvet as shown in FIG. That's what happens.

In this way, in the above embodiment, the filling tool 13 is inserted into the passage 14, and the tip end 13 of the filling tool 13 is inserted into the passage 14.
a into each sub-divided chamber 12 from the filling port 16 or the opening 8 of the compartment chamber 5, and in this state, the inside of the futon fabric bag 9 is preliminarily filled by blowing the feathers 4 with air or the like. Even though it is divided into small sections, it is possible to fill all the sub-divided chambers 12 with feathers 4.

When handling the futon manufactured as described above, for example when folding the futon, even if the futon is in a tilted state as shown in FIG. Since it is formed apart from one end 3a, the feathers 4 press down on the cloth piece 15 as shown in the figure, and as a result, the filling port 16 is closed.

Therefore, the feathers 4 do not enter the passage 14 and do not move toward the adjacent sub-divided chamber 12.

In addition to being formed in the lateral direction of the piece of cloth 15 as in the above embodiment, the filling port 16 formed by a notch may be formed diagonally, for example, as shown in FIG.

Further, in the above embodiment, the filling port 16 is formed by cutting out the cloth piece 15 at equal intervals, but the filling port 16 does not necessarily have to be formed by such notches. A plurality of cloth pieces 15 may be overlapped as shown in FIG.

Furthermore, the passage 14 is not limited to one formed continuously as in the above embodiment, but may be formed, for example, from both ends of the futon fabric bag 9 to an adjacent room and divided in the center, as shown in FIG. It may be of such form.

In the embodiment shown in FIG. 9, as shown in FIG.
is formed, and is also vertically divided into four to form a total of 20 sub-divided chambers 12, . . . .
In this embodiment, among the four vertical rows of sub-divided chambers 12,..., the inner two rows of sub-divided chambers 1
2 is filled with feathers 4 from the filling port 16 of the cloth piece 15, and the outer two rows of subdivided chambers 12 are filled with feathers from the opening 8 of the futon fabric bag 9. The openings 8, 8 on both sides are sealed.

Also in this embodiment, as shown in FIG. 9D, even when the futon is in a tilted state during handling, the cloth piece 15 is pressed by the feathers, and the filling port 16 is therefore blocked. Small division room 1
The feathers 4 in the filling port 16 do not inadvertently move toward the adjacent sub-divided chamber 12.

Furthermore, in this embodiment, the filling port 16 is formed at one end of the passage 14 formed by the cloth piece 15, and the sub-divided chambers 12 are formed in four vertical rows.
The sub-divided chambers in the second and third rows can be filled with feathers 4 through the filling port 16, and the sub-divided chambers in the first and fourth rows can be filled with feathers 4 through the openings 8 and 8 on both sides of the compartment 5. Therefore, the filling port 16 is formed at the tip 13a of the filling tool 13, such as the filling port 16 formed by a notch as in the embodiment shown in FIG. This eliminates the need to search for feathers, which has the advantage of making the feather filling work easier overall.

Further, the means for fixing the cloth piece 15 is not limited to the ultrasonic welding of the embodiment, but may also be heat fusing, sewing, or the like.

Furthermore, the side areas 1a of both ends 3a and 3b of the partition piece 3,
1b or the interlining 2 is not limited to heat fusion as in this embodiment, but may also be adhesive, high-frequency welding, etc., or the interlining 2 may be fixed to the interlining 2 by sewing other than fixing. It may be attached to.

Further, the means for fixing the inner fabric 2 and the side fabrics 1a, 1b is not limited to the case where a heat-fusible tape is used as in the embodiment. Both may be fixed by heating thereafter.

Furthermore, in this embodiment, a large number of partition pieces 3,... are all provided in one direction, but each partition piece 3,... may be provided in different directions, for example as shown in FIG. is never a question.

Further, in this embodiment, a large number of partition pieces 3, .

Further, the material of the sheet material forming the passage 14 is not limited to the cloth like the cloth piece 15 of the embodiment, but may be made of synthetic resin, for example, and the material thereof is not limited.

Furthermore, the material of the side fabrics 1a and 1b is not limited to the polyamide-based synthetic resin of the above embodiment, but may be other synthetic fibers, natural fibers, or a mixture of synthetic fibers and natural fibers. Well, the material is never in question.

However, when synthetic fibers whose edges are fused and solidified by heating are used as the material for the side fabrics 1a and 1b, the edges of these fabrics 1a and 1b do not fray, so frayed threads are coated with feathers. There is an advantage that 4 does not become entangled.

In addition, in this embodiment, nonwoven fabric is used as the material for the interlining 2, the partition pieces 3, and the cloth pieces 15, so
Although these fabrics also have the advantage of not getting entangled with the feathers 4, the materials of the interlining 2, the partition pieces 3, and the cloth pieces 15 are by no means limited to the embodiments described above.

Furthermore, in this embodiment, since the interlining 2, the partition pieces 3, and the cloth pieces 15 are formed into a net shape with a large number of small holes, the air permeability necessary for the feathers 4 is maintained, and the interior of the sub-divided chambers 12 is There is an advantage that the compressed air pumped into the feathers escapes through the small holes, making it easier to fill the feathers 4, but forming the feathers 4 in a net shape is by no means a condition.

Incidentally, the filling material inside the futon is not limited to the feathers of the above embodiments, but may also be made of, for example, cotton or the like.
The type of filling does not matter.

Furthermore, the inner material 2 and the side material 1 of the other end 3b of the partition piece 3
The heating and fusing to a and 1b does not necessarily need to be performed over the entire width in the longitudinal direction or the lateral direction as in the embodiment, and may be performed, for example, in a dotted manner.

Further, the shape of the filling device 13 is not limited to the shape in which the distal end portion 13a is curved as in the embodiment, but may simply be a pipe shape, and the shape is by no means the same.

(Effects of the Invention) As described above, the present invention attaches both ends of the compartment pieces to the side fabric and the center fabric in advance when forming a bag for futon fabric to form subdivided chambers within the compartment, and also fills the bag. Although the futon fabric bag is divided vertically and horizontally, it is possible to By inserting a filling tool into the passage and allowing the tip of the filling tool to emerge from the filling port into each sub-divided chamber, all the sub-divided chambers can be sequentially filled with filler such as feathers. This has resulted in a particularly remarkable effect of making it possible.

Furthermore, since the entrance of the passage is formed near the opening of the compartment, the filling tool can be easily inserted from the entrance, and
Since the passage is formed of a long and narrow sheet material, the filling tool is reliably guided along the passage, and the filling operation as a whole becomes significantly easier than in the past. There is an effect.

Furthermore, because the futon bag is divided vertically and horizontally, the filling material only moves within the range of the subdivided chambers, which prevents the filling material from being unevenly distributed within the bag as in the past. This has the effect that the filling can be maintained in a uniform state within the futon even after long-term use.

In particular, the filling port is formed at a position spaced apart from the compartment by a predetermined distance so that the filling port does not move between adjacent sub-chambers through the filling port, so that the filling port does not move between adjacent sub-chambers. The elongated sheet material is completely pressed down and the filling port is closed,
As a result, there is no movement of the filling between adjacent sub-compartments as in the past, and there is a remarkable effect in that the entire futon bag can be prevented from being filled unevenly. .
