Description

[0001]
[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a good-feel fabric bag using soft elastic fabric on the outside.
[0002]
[Prior art]
Conventional cloth bags need to be strong for the purpose of carrying luggage, and have been manufactured using rigid non-stretchable fabrics such as denim and nylon oxford.
[0003]
Therefore, there was a problem that the fabric was hard and the feel was not good. In order to solve this problem, there has been a demand for a cloth bag using a soft and elastic cloth such as a knit.However, when a cloth bag is made of such cloth, the cloth grows due to the weight of the luggage. There was a problem that it would quickly lose shape.
[0004]
[Problems to be solved by the invention]
In view of the foregoing, an object of the present invention is to solve the above-mentioned conventional problems and to provide a cloth bag which has a soft and comfortable feeling when touching the surface of a bag and which does not lose its shape even when luggage is inserted. And
[0005]
[Means for Solving the Problems]
Therefore, according to the first aspect of the present invention, an inner bag 2 made of a non-stretchable fabric is sewn to the inside of an outer bag 1 made of a stretchable fabric to form a sealed inner bag. A foam bag 3 was sealed between the bag 1 and the interior bag 2, and the cloth bag was further provided with hands 4, 4 formed continuously with the interior bag 2 above the interior bag 2.
[0006]
According to the second aspect of the present invention, an interior bag 2 made of a non-stretchable fabric is sewn to the inside of an exterior bag 1 made of a stretchable fabric to form a sealed inner bag. A foamed bead 3 is sealed between the inner bag 2 and the inner bag 2, and the cloth bags are further provided with the hands 4, 4 attached to the upper part of the inner bag 2.
[0007]
According to the third aspect of the present invention, an interior bag 2 made of a non-stretchable fabric is sewn to the inside of an exterior bag 1 made of a stretchable fabric to form a sealed inner shape. A foam bead 3 was sealed between the inner bag 2 and the inner bag 2, and a shoulder bag was attached to the upper portion of the inner bag 2 to form a cloth bag.
[0008]
In the cloth bag according to any one of claims 1 to 3, not only is the outer bag 1 made of a stretchable fabric, but also foam beads are enclosed inside, and the outer bag 1 is touched by the fluidity of the foam beads. When touched, it becomes soft like a stuffed animal or cushion.
[0009]
Further, in the cloth bag according to the first to third aspects, the weight of the luggage is supported by the inner bag 2 made of non-stretchable fabric, and the outer bag 1 hardly receives the weight of the luggage. Does not crumble.
[0010]
It is preferable to use a spherical bead 3 having a foaming rate of 25 to 60 times and a diameter of 0.5 to 1.0 mm.
[0011]
By doing so, the fluidity and feel of the foam bead 3 become good.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a cloth bag according to the present invention will be described with reference to FIGS. 1, 2, and 3. FIG.
[0013]
In this embodiment, a tote bag will be described, but the type of cloth bag is not limited to a tote bag, and any type of cloth bag can be used.
[0014]
FIG. 1 is a perspective view of a tote bag which is an embodiment of a cloth bag of the present invention, and FIG. 2 is a cross-sectional view cut from the center.
[0015]
In this tote bag, an inner bag 2 made of a non-stretch fabric is sewn to the inside of an outer bag 1 made of a stretchable fabric to form a sealed bag. A foam bead 3 is sealed between the inner bag 2 and a pair of hands 4 and 4 formed continuously with the inner bag 2 at the upper part of the inner bag 2. The grips 5 and 5 made of leather formed in a shape are attached. The outer bag 1 is formed to be somewhat larger than the inner bag 2 so that the weight of the luggage put in the cloth bag is supported by the inner bag 2 mainly made of non-stretchable fabric. Is designed so that the weight of the baggage is almost negligible.
[0016]
The pocket 6 formed on the side surface of the outer bag 1 is for storing a mobile phone.
[0017]
Hereinafter, each component will be described in detail.
[0018]
It is preferable to use a stretchy fabric having elasticity by a knitting method such as a knit or the like, but a stretch fabric such as spandex may be used as the stretchable fabric constituting the outer bag 1. The material of the thread to be used can be arbitrarily selected such as wool, cotton, polyester and the like.
[0019]
The non-stretchable fabric constituting the interior bag 2 is selected from strong fabrics conventionally used as bag fabrics, such as denim and nylon oxford.
[0020]
The foam bead 3 is formed by foaming a synthetic resin such as a polystyrene resin, a polyethylene resin, or a polypropylene resin into a spherical shape. The foam bead 3 has a moderate expansion ratio in the range of 25 to 60 times and has a suitable elasticity, and is suitable from the viewpoint of softness. When the expansion ratio exceeds 60 times, it is too soft and easily sags. The diameter of the foamed bead 3 is preferably 0.5 to 1.0 mm from the viewpoint of fluidity and feel. If the diameter is less than 0.5 mm, the foamed bead 3 is likely to be hardened and the fluidity deteriorates. When the thickness exceeds 1.0 mm, the shape of the internal foam bead 3 can be recognized by touching from the outside of the outer bag 1, and the feeling when touched becomes worse.
[0021]
In this embodiment, the example in which the handle 4 is formed continuously with the inner bag 2 is shown, but the handle 4 may be provided by sewing the inner bag 2 or the like.
[0022]
FIG. 3 is a sectional view showing a second embodiment of the present invention, in which a sheet 7 made of a thin plastic sheet, a thin cloth, or the like is placed inside the outer bag 1.
[0023]
In this way, even if the outer bag 1 is damaged during use and a hole is opened, the foam beads 3 are prevented from protruding to the outside by the sheet 7. Thus, a configuration for preventing leakage of the foam beads 3 can be added and implemented.
[0024]
The above is the description of the configuration of the cloth bag of the present invention. Next, the mode of use will be described.
[0025]
When the luggage is stored in the cloth bag and the bag 4 is lifted down, the weight of the luggage is supported by the inner bag 2 and the weight of the luggage is hardly applied to the outer bag 1. Therefore, the outer bag 1 does not stretch and the cloth bag does not lose its shape.
[0026]
Furthermore, the cloth bag of the present invention has a soft touch like a stuffed animal or a cushion due to the outer bag 1 and the foam beads 3, so that it can be comfortably placed on the knee. It has become.
[0027]
Since the cloth bag of the present invention contains the foam beads 3 between the outer bag 1 and the inner bag 2, it can be used for the following applications.
{Circle around (1)} The foam bead 3 can be used as a cloth bag for transporting electronic devices such as a notebook computer which protects external impacts by utilizing the cushioning properties of the foam beads.
{Circle around (2)} Since the foam beads 3 also have an effect as a heat insulating material, they can also be used as simple warm / cold bags (for example, shopping bags).
[0028]
The above is the description of the embodiment of the present invention, and the example of the tote bag provided with the fulcrum 4 has been described. In addition, although the example in which the handle 4 is formed integrally with the interior bag 2 is shown, it can be attached to the interior bag 2 as a separate body, and the shape of the handle 4 can be changed arbitrarily.
[0029]
Furthermore, a chuck may be attached to the opening of the cloth bag so that the opening of the interior bag 2 can be opened and closed.
[0030]
【The invention's effect】
In the cloth bag of the present invention, the outer bag 1 is constituted not only of a stretchable fabric but also has a foam bead enclosed therein, as described above. The touch feel is soft, like a stuffed animal or cushion, so it feels good when placed on your knees. Furthermore, the weight of the luggage is supported by the interior bag 2 made of non-stretchable fabric, and the outer bag 1 hardly receives the weight of the luggage.
