Description

[Detailed description of the invention] This invention relates to a synthetic resin film bag that can be carried by hand and has gussets folded in on both sides. This relates to bags used for hanging and transporting.

Conventionally, in this type of bag, a U-shaped opening is formed at the top of the bag, the sides of this opening are placed over the gussets on both sides, and finger holes are formed near the gusset flesh.

However, in this conventional bag, the rim is rectangular in plan when the bag is being held down, and products may spill or fly out from the rim when the bag is carried.

To prevent this, the edges of the bag are secured with staples and adhesive tape, but when the bag is tipped over, the product tends to spill out from the sides of the bag.

The purpose of this invention is to improve the drawbacks of the above-mentioned carrying bags and to provide a synthetic resin bag that prevents products from spilling from the rim.

In this device, the gussets are folded in on both sides, and the lower end is welded across the entire width to form the bottom of the bag.On the raised edge side, a U-shaped notch with both ends located at this upper edge is provided toward the bottom of the bag. A cut is made from the upper end of the gusset welded in the width direction of the bag toward the bottom of the bag at a position parallel to the sides of the U-shaped opening and avoiding the troughs of the gusset. It is provided through the gusset part, and the length of this cut is U.
This synthetic resin bag is characterized in that the side lengths of the U-shaped opening are the same, and strings are formed on both sides of the U-shaped opening.

Next, typical embodiments of this invention will be explained based on the drawings.

First Embodiment (See FIG. 1) In the figure, reference numeral 10 denotes a synthetic resin bag with gussets 11 folded in on both sides.

On the flaming edge 13 side, a U-shaped notch is provided with both ends located on the upper edge 13 toward the bottom 12 of the bag 10,
A U-shaped opening 14 is formed.

Both sides 15 and 16 of this U-shaped opening 14 are located closer to the center of the bag than the gusset trough 11a, that is, at positions that do not overlap the gusset trough 11a.

The upper edge of the bag is welded in the width direction of the bag from the upper end of the sides 15, 16 of the U-shaped opening 14 to the side of the bag.

This gusset 11 is cut from the upper end of the welded gusset 11 toward the bottom 12 of the bag at a position where the cut line 17 is parallel to the sides 15 and 16 of the U-shaped opening 14 and avoids the valley 11a of the gusset 11. This cut line 1
The length of 7 is the same as the length of the sides 15 and 16 of the U-shaped opening 14, and strings 18 are formed on both sides of the U-shaped opening 14, and the strings 18 A handheld portion 19 is formed on the outside.

This string 18 consists of three strings 18a, 18b and 18C, which are welded and integrated at the upper end 18d.

Of the above three strings, 18a and 18C are formed from the front and back films of the bag 10, and the center string 18b is a part of the gusset folded film that is folded in half, and is made from two films connected at the gusset trough 11a. I warn you.

Reference numeral 20 denotes a tear prevention hole provided at the lower end of the cut line 17.

Second embodiment (see FIG. 2) Both sides 1 of the U-shaped opening 14 in the first embodiment
5. The position of 16 is changed, a part of the gazette valley part 11a is notched, and it is located on the gazette mountain part side.

The rest is the same as the first embodiment. In this embodiment, the strings 18 formed on both sides of the U-shaped opening are each made up of four strings 18a, 18"i, 18h2t, 18c, and the middle strings 18b, 18b2 are made of gusseted film. are separated from each other.

Third embodiment (see Figure 3) Discontinuous cut 17 in place of the score line 17 in the first embodiment
Apply a.

The other configurations are the same as the first embodiment.

Fourth embodiment (see FIG. 4) U-shaped opening 14a and the discontinuous cut 1 of the second embodiment
7a, and the other configurations are the same as the first embodiment.

The operation of the present invention having the above configuration will be explained next.

To put the product into this bag, press the folded side gazette 11.
The bag is extended and the product is placed into the bag from the rectangular opening.

Next, the strings 18 located on both sides of the U-shaped opening are brought down to a horizontal position, and the upper end welded portions 18d of each set 18 are bound or stapled together when viewed from above.

At this time, the strings 18a and 18c extending from the front and back films of the bag extend obliquely from the tip of the cut line 17 or the discontinuous cut 17a, that is, the base of the carrying portion 19, to the center of the bag's mouth edge, and are further folded into the gusset of the bag. A string made of a thin film extends from the side of the bag to the center of the mouth edge, and is attached to the mouth edge 18 in a spider web pattern.
(18a? 18bt 18c) is strung out.

After the string 18 is stretched around the rim in this way, the bag containing the products is carried in the hand by passing the finger through the hole in the inner part of the gazette 11 in the carrying part 19.

Among the embodiments, in an embodiment in which both sides 15, 16 of the U-shaped opening 14 do not overlap the gusset valley 11a,
A total of six strings are strung around the rim of the bag, which is spread out into a rectangular plane.
It will be folded in two.

Further, in an embodiment in which both sides 15 and 16 of the U-shaped opening 14 are located by cutting out a part of the gusset valley, eight strings are wound around the opening edge, and the middle string 18bi
t 18b2 is separated from each other.

The effects of the present invention, which is constructed and operated as described above, are as follows.

In the present invention, a cut having the same length as the side length of the U-shaped opening 14 runs parallel to the side edge of the U-shaped opening from the top end of the gusset part 11 welded in the bag width direction toward the bottom. This gazette 11 is located at a position avoiding the valley 11a of the gazette 11.
The cord 18 is formed on both sides of the U-shaped opening 14 by this cut.
The bag consists of three or four strings consisting of part of the front and back film of the bag and part of the gusseted film, and each set is welded together at the upper end.

As a result, by tying the left and right strings 18 together, 6 or 8 strings are threaded around the edge of the bag in a spider web shape.
Even if the bag falls on its side, the spider-web-like strings can reliably prevent the products contained inside the bag from flying out from the bag's rim.

Next, due to the presence of the cut 17, when the edge 19 is fitted around the mouth edge of the bag 13, finger holes are formed near the flesh of the gusset near the upper end, and fingers are inserted into the left and right finger holes. By threading it through, the synthetic resin bag of this invention can be carried by hand.

The center string, which is cut from a part of the gusseted film, has its base connected to the side of the unfolded side gusset bag, and while applying a force to draw this side inward, the left and right strings 18 adjust the spinning speed. Therefore, it is possible to more reliably prevent the product from flying out from the edge of the bag.

Furthermore, since the above-mentioned cuts are cut in the direction from the upper end of the gusset welded in the width direction of the bag toward the bottom of the bag, the three strings 18 forming the strings 18 formed on both sides of the U-shaped opening 14 are cut. Alternatively, the four strings are welded together at the upper end, making it easy to tie the left and right strings together, staple them, etc.

The effects of the embodiment are as follows.

If the above-mentioned cut is a discontinuous cut 17a, when putting the product into the bag, the string 18 is connected to the handle part 19 and the discontinuous cut 17.
Since the string 18 is still connected to the handle part 19, it is possible to smoothly put the product into the bag without the string 18 getting in the way. The left and right strings 18 can be tied together, stapled, or adhesive tape can be used to prevent small items from flying out from the edge of the bag.

When the above-mentioned cut is the cut line 17, the string can be threaded around the edge of the bag like a spider's web without separating the carrying part 19 from the string 18.

Both sides of the U-shaped opening 14 are the side gusset valleys 11.
In some embodiments, the central string 18b, which is made of a part of the film folded into the gusset, extends from the two films communicating at the gusset trough, and the bag When stringing the string around the mouth rim, the base of this center string 18b will be spread out and connected to the side of the side gusset bag, and when tying the left and right strings 18 together, Attach this center string 1 to the side of the bag.
You can pull it with 8b.

In an embodiment in which both sides 15, 16 of the U-shaped opening 14 cut out a part of the side gusset valley 11a, the edge 18 has four strings 18a, 18bi, 1
8b2 and 18c, more strings can be threaded around the rim of the bag in a spider web shape than when the central string 18b is made of two films.

By providing the round hole 20 at the tip of the cut, it is possible to prevent the cut from being torn from the tip toward the bottom of the bag when tying the left and right strings 18.
