Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag mainly for storing and carrying articles (particularly referred to as a handbag, hereinafter the same) or a bag mainly for storing and storing articles. (In particular, referred to as a storage bag, the same applies hereinafter).

[0002]

2. Description of the Related Art In recent years, in order to reduce the amount of garbage, it is becoming more and more common for consumers to bring a handbag with them to take home items bought at supermarkets and department stores. Conventional handbags are often made of a thin material so that they can be folded into small pieces when they are not needed. For example, nylon woven cloth is used on both sides, and the upper and lower edges can be opened by sewing the side and lower edges. However, the articles are stored in a bag with the upper edge opened, and the articles are usually carried by putting a hand into a handle hole provided in the vicinity of the upper edges on both sides.

Such a bag structure is often found in leisure bags, clothes carry bags, and the like. Furthermore,
Storage bags such as bag storage bags, futon storage bags, clothes storage bags, etc. for the purpose of storing and storing articles instead of transporting have almost the same structure. In the case of the latter storage bag, in order to protect the goods from dust etc. during storage, the woven fabric that constitutes the bag is sewn together at all edges to form a closed structure, and a fastener is sewn into the opening provided in this bag. It is used as a doorway for goods.

[0004]

The above-mentioned handbag or storage bag requires a lot of time and labor to sew a woven fabric or a thick non-woven fabric, and it is difficult to reduce the production cost. Moreover,
In the worst case, if the sewn part is unraveled, it may not be able to function as a bag. Further, in the case of the handbag only, since the upper edge is opened to serve as an entrance / exit of the article, there is a problem that the base cloth near the handle hole is often tampered with and is easily torn.

[0005] Therefore, while reducing the manufacturing cost as a storage bag or a handbag, an opening with a fastener is used as an entrance / exit of the article to ensure the tightness of the bag so as not to impair the ease of storing and taking out the article during use. We decided to study the structure of bags that can be made, especially those with fasteners.

[0006]

What was developed as a result of the investigation was a bag formed by welding a plurality of weldable non-woven fabrics around the periphery of the non-woven fabrics, and having a weldable tape at the opening of the bag. It is a non-woven bag with a fastener to which this weldable tape of a fastener is attached by welding. The welding method includes heat welding and ultrasonic welding.

In the bag of the present invention, a non-woven fabric having a weldability is used as a base fabric constituting each side of the bag, so that a plurality of non-woven fabrics can be easily formed by heat welding or ultrasonic welding instead of conventional sewing. Since the bag can be formed by connecting them, and the fastener that serves as the entrance and exit of the article is attached to the nonwoven fabric by welding, the bag can be manufactured easily and at low cost. The fastener prevents the dissipation of stored items and enhances the airtightness of the bag, and is particularly suitable for a storage bag intended for storage and storage.

For example, 6 corresponding to each of 6 rectangular parallelepipeds
A futon storage bag can be obtained by welding a plurality of non-woven fabrics to each other at their peripheral edges to form a box-shaped bag, and providing an opening on one surface having a large area and attaching a fastener. In addition, two non-woven fabrics cut according to the outer shape of the suit are welded on the peripheral edge of the hanger, leaving the neck around which the hook of the hanger protrudes, and an opening is provided on one surface downward from the neck and the fastener. When attached, it can be used as a clothes carry bag or a clothes storage bag.

When the handle hole is opened by communicating with the facing non-woven fabric of the bag, and the non-woven fabrics near the handle hole are welded to each other to form a reinforcing portion, the non-woven fabric near the handle hole is always doubled. It is possible to make a handbag that does not easily tear around the handle hole. The fastener is preferably provided along the reinforcing portion on the side opposite to the handle hole. For example, in the vicinity of the upper edge of the bag in which two rectangular non-woven fabrics are welded together at their peripheral edges, a handle hole communicating with both sides is opened, and a reinforcing portion parallel to the upper edge is provided directly below this handle hole. The fasteners are provided and the fasteners are attached to one side or both sides of the reinforcing portion facing away from the handle hole.

By laminating a plastic film (hereinafter simply referred to as a film) on the outer surface of the non-woven fabric (the outer surface of the bag) constituting the above bag, the bag is provided with waterproof property and the bag surface can be easily soiled. The dirt can be removed. Further, when a film is laminated on the inner surface of the nonwoven fabric (the inner surface of the bag), a wet product can be put in this bag. Laminate does not have to be provided on the entire surface of the nonwoven fabric forming the bag,
For example, a handbag may be laminated on only one side. The lamination of the film on the non-woven fabric is preferably performed at the raw material stage such as a roll in which the non-woven fabric is wound, because the production efficiency is improved, rather than the individual products being welded and completed.

When a pattern, mark or character is printed or drawn on the inner or outer surface of the laminate applied to the outer surface of the nonwoven fabric,
It is possible to make a simple storage bag or handbag with excellent design. It is usual that the film is made transparent to clearly show the pattern and the like, but the film itself may be colored. Since the pattern or the like printed or drawn on the inside of the laminate is protected from the outside by the laminate, there is no fear of fading or peeling due to abrasion.

As the non-woven fabric having the weldability, polyester non-woven fabric, polypropylene non-woven fabric, nylon non-woven fabric, polyethylene non-woven fabric or the like can be used alone or in combination. The fibers are mixed and woven, or the fibers are woven only by the fusible fibers having the same melting point as the non-woven fabric so as to have the fusible properties. The film to be laminated may be a polyester film, a polypropylene film, a nylon film, a polyethylene film, or the like.

As the basis weight of the non-woven fabric, those having a weight of 15 to 150 g / m ² can be used, but considering the reduction of manufacturing cost and the strength as a product, it is preferable that the weight is about 30 to 100 g / m ^2. . Further, as a method of welding, heat welding is easy, but since it is difficult for heat to pass through a thick non-woven fabric exceeding 50 g / m ² , it is preferable to use ultrasonic welding. In particular, ultrasonic welding is preferable for laminated nonwoven fabrics,
The portion thus welded enhances the strength of the bag.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a nonwoven fabric bag with a fastener and a handbag according to the present invention will be described with reference to the drawings. 1 is a perspective view of a handbag 1 according to the present invention, and FIG. 2 is FIG.
FIG. 3 is an AA cross-sectional view, and FIG. 3 is an exploded perspective view of the handbag 1. The bag 1 shown in FIGS. 1, 2 and 3 is formed by combining two large non-woven fabrics 3 each having a predetermined length from the lower edge as the bottom and a predetermined length from the upper edge to form the handle hole 2. After ultrasonically welding the side edges 4 and the edge 6 and the surface folded back from the upper edge with a predetermined length as the reinforcing portion 5, and only the edge 7 folded back with a predetermined length from the lower edge,
The handle hole 2 is opened at a predetermined position from the upper edge, and a handle reinforcing member 23 made of plastic is further attached to the handle hole 2. The opening provided in the non-woven fabric 3 on one side along the reinforcing portion 5 located immediately below the handle hole 2. 8 has a structure in which a fastener 10 having a weldable tape 9 is ultrasonically welded. The fastener 10 may be attached vertically along the side edge of the handbag 1 or may be arranged in an L shape from the horizontal direction to the vertical direction. The non-woven fabric 3 constituting both sides of the handbag 1 is laminated with a film 11 having a flower picture 12 printed on its inner surface in advance at the stage of the original fabric.

As can be seen from FIGS. 2 and 3, the non-woven fabric 3 constituting each of both sides of the handbag 1 of this example has its upper edge folded back to a predetermined length, and the portions where the handle holes 2 are opened are doubled. On the other hand, the entrance and exit of the article, which was the open end of the conventional upper edge of the handbag, was changed to a fastener 10 attached to the opening 8 on one side, and parallel to the upper edge of the handbag 1 just below the handle hole 2. Moreover, since the reinforcing portion 5 ultrasonically welded to both side edges is provided, and in particular, the handle reinforcing member 23 is attached to the handle hole 2 in this example, the strength in the vicinity of the handle hole 2 is higher than that of the conventional handbag. It has improved significantly. Moreover, since ultrasonic welding is used instead of sewing to create such a structure, the manufacturing is very simple and the cost is low.

Further, since the whole is made of the soft and thin non-woven fabric 3, the handbag 1 can be folded as shown in FIG. 4, and the thickness is thin even after the folding, so that the small bag or debug bag, In some cases, it can be stored in a pocket of clothes. Thus,
For example, the handbag 1 of this example can be used in such a form that it can be put in a handbag in a folded state and carried, taken out after shopping, unfolded, and the purchased article can be stored and brought back.

In order to maintain the strength of the whole handbag to store and carry or store the articles, the handbag is formed of a relatively thick non-woven fabric as the storage amount is increased, or a handle hole is used as in this example. It is necessary to improve the strength by, for example, doubling the non-woven fabric in the vicinity of 2, and ultrasonic welding is used for welding. However, when the storage amount may be small, a small handbag is made of a single thin non-woven fabric, and since heat welding can be used for welding, the bag can be manufactured at a lower cost. Further, such a thin handbag has the advantage that it can be folded more than four in FIG. 4 to make it smaller.

FIG. 5 is a perspective view of the futon storage bag 13 according to the present invention, and FIG. 6 is a fastener 14 for the entrance and exit of the futon.
FIG. 3 is a plan view of a non-woven fabric 15 which constitutes the futon storage bag 13 to which is attached. The futon storage bag 13 can be formed by laminating two non-woven fabrics 14 each having an external shape shown in FIG. Unlike the conventional futon storage bag by sewing, the futon storage bag 13 of the present invention by welding is easy to manufacture,
It can be made at a lower cost, and moreover, the joining of the nonwoven fabrics by welding has a higher degree of integrity than sewing, and by further laminating the surface of each nonwoven fabric 14 with the film 11, it is more resistant to tearing and waterproof, and The surface of the futon storage bag 13 does not easily get dirty.

As another example, as shown in FIG. 7, two non-woven fabrics 16 cut to fit the outer shape of a suit are
The fastener 18 is welded by ultrasonic welding a weldable tape to the opening provided on one surface downwardly from the neck circumference, leaving the neck circumference 17 from which the hook of the hanger protrudes. The attached clothes storage bag 19 can be mentioned. As shown in FIG. 8, the garment storage bag 19 is transformed into a form in which the bag portion 21 provided below is folded back and passed through the hook as the garment carry bag 22 as shown in FIG. It is portable. As described above, the present invention can be applied to various bags to be stored, transported or stored, and can further reduce manufacturing cost and improve convenience in use such as strength, strength, and the like, and provide a product superior to conventional products. It can be provided.

[0020]

The non-woven fabric bag with a fastener of the present invention, on the other hand, has been developed with a fastener having a tape capable of being welded, particularly ultrasonically welded. While making it easier to manufacture by lowering the unit price of the product, on the other hand, it has a portability that does not become bulky even if it is thinly folded, while not only using thick non-woven fabric but also welding with a double structure. By laminating and laminating, the strength, waterproofness, and performance improvement such as suppressing the adhesion of dirt are achieved, and it is more cost-effective than the conventional storage bag or handbag.
(Cost performance) is increasing.

In addition to the above-mentioned handbag, futon storage bag, garment storage bag or carry bag, these features can be applied to any bag with fasteners such as golf bags, shoe bags, ski ski storage bags and carpet storage bags. Applicability is the greatest effect of the present invention.
