Problems solved by technology

However, the nonwoven bag made of nonwoven fabric is manufactured by sewing nonwoven fabric sheets together with a sewing machine, etc., so it takes labor and time to manufacture, and there is a problem that the manufacturing cost increases.
Therefore, since the sewn non-woven bag becomes more expensive than the paper bag, there is a problem that it is difficult to purchase easily when using it for a temporary use.

Embodiment 1

[0082] The non-woven bag 1 with a handle of embodiment 1 is equipped with a bag body 2 and a handle 3 made of polyester yarn or polypropylene yarn (refer to figure 1 ), the bag bottom 4 can be folded (refer to figure 2 ).

[0083] Fold a 76cm×112cm rectangular non-woven fabric sheet in half so that the short sides overlap each other, fold the sheet including its crease 7 inwardly (valley fold) 7.5cm, and seal it by pulse heat (basic condition: heater (a pair of cylinders: each cylinder has a diameter of 0.9mm), heating (sealing) time of 4 seconds, voltage of 220V, and instantaneous current of 45A) The side edges 8 of the bag are bonded together.

[0084] The bag body 2 has a length of 76 cm and a height of 45 cm. The bottom of the bag 4 is approximately elliptical with a minor axis of 15 cm and a major axis of 30 cm. The edge of the opening is bent inward by 3.5 cm, and the distance from the edge of the opening is 0.5 cm and 3.0 cm. Ultrasonic sealing is performed on the tw...

Embodiment 2

[0088] The non-woven fabric bag 21 with a handle made of non-woven fabric of embodiment 2 is equipped with a bag body 22 and a handle 23 made of polyester yarn or polypropylene yarn (refer to image 3 ), the sides can be folded (see Figure 4 ).

[0089] A rectangular non-woven fabric sheet of 76 cm x 112 cm is folded in half so that the short sides overlap each other, and the sheet including the crease 27 is folded inward by 7 cm and cut off, and then sealed by pulse heat (basic conditions: heater ( A pair of cylinders: the diameter of each cylinder is 0.9mm), the heating (sealing) time is 4 seconds, the voltage is 220V, and the instantaneous current is 45A) to join the side edges 28 of the bag.

[0090] The front and back of the bag body 22 have a width of 22 cm, a left and right side width of 14 cm, and a height of 45 cm. The bag bottom 24 is roughly rectangular in shape. Ultrasonic sealing (basic conditions: voltage 220V, current 1A, speed 4m / min) of the 2 parts in a knu...

Abstract

A nonwoven fabric bag includes: a bag body; and a pair of handles. A fabric sheet is folded in two. A bottom of the bag is formed by a sheet portion including the fold line. Side edges of the opposing folded halves of the sheet are bonded together on right and left sides to form a bag. A sheet portion along a peripheral edge of an opening of the bag is folded inward and bonded to form a double-layer portion, thereby forming the bag body. Two strips are attached to the double-layer portion, thereby forming the pair of handles. The side edges are bonded by impulse heat sealing. The peripheral edge of the opening and a vicinity thereof, and a part connecting to the fold line are sewn. The double-layer portion is bonded by discontinuous ultrasonic sealing. Attachment portions between the double-layer portion and the handles are sewn.

Description

technical field [0001] The invention relates to a non-woven fabric bag with a handle. Specifically, it relates to a nonwoven fabric bag with a handle, which can be manufactured with reduced manufacturing labor and cost, and is less likely to be damaged even when a bulky or heavy item is put in it. Background technique [0002] In the past, paper bags or cloth bags with handles were used when carrying items with one's hand. In particular, women often walk with small bags such as handbags, so when carrying items to the destination or when returning with items that have increased at the destination, etc., they often use a belt bag. Paper bag or cloth bag in hand. [0003] Paper bags with handles are lighter and thinner when folded so they are easy to carry, but in turn are weaker and have a defined shape, so they are not suitable for carrying heavier and / or bulky items. In contrast, cloth bags with handles are stronger and can change in shape to match the shape of the item, ...
