[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The packaging bag of the present invention will be described in detail below with reference to the drawings shown as an embodiment.

FIG. 1 is a plan view of the packaging bag of the present invention, in which two quadrangular synthetic resin films 1 are stacked and a pair of adjacent two sides 1a and 1b, that is, the upper side and the right side. A seal portion 2 is provided near the side, and another pair of adjacent two sides 1c and 1d, that is, a seal portion 3 having peel strength capable of being peeled off by the force of a human hand is provided near the lower side and the left side. In addition to the provision, the non-sealing portion 4 is provided at the adjacent two sides 1c and 1d, that is, the intersection end portion of the lower side and the left side.

The synthetic resin film 1 is made of, for example, a thermoplastic resin such as polyester, polyethylene, polyethylene terephthalate, or polypropylene, and is vapor-deposited with alumina if necessary to have a gas barrier property.

The pair of two adjacent sides 1a and 1b are the upper side and the right side of the synthetic resin film 1 in this embodiment, but may be the lower side and the left side of the synthetic resin film 1. Further, another pair of adjacent two sides 1c and 1d are the lower side and the left side of the synthetic resin film 1 in this embodiment, but may be the upper side and the right side of the synthetic resin film 1.

The seal portion 2 is, for example, heat-sealed. The seal portion 2 has a peel strength that can be peeled off by the force of a human hand, that is, a peel strength that cannot be peeled off by the force of a human hand even if it is subjected to so-called easy peeling. The so-called permanent processing may be performed.

The seal portion 3 is, for example, heat-sealed. The seal portion 2 is so-called easy peeling, which has a peeling strength that can be peeled off by the force of a human hand.

The non-sealing portion 4 has two adjacent sides 1c,
Although a part of the inner side of the crossing end of 1d is left without being heat-sealed, the crossing end of these two sides 1c and 1d may be projected to the outside so that the projecting part is not heat-sealed. . The non-sealing portion 4 is formed by inserting a fingertip of a hand and picking an end portion of the synthetic resin film 1 to easily tear the heat-sealed sealing portion 3.
The size is large enough to allow the fingers of the hand to be inserted.
Further, the non-seal portion 4 tears the seal portion 3 by bending one side of the synthetic resin film 1, cutting one side of the synthetic resin film 1 a little short, or providing a through hole in the synthetic resin film 1. It can be used as a time mark.

Further, the packaging bag of the present invention is provided on either one side of the two sides 1a, 1b, in this embodiment, on both sides or one side (both sides in this embodiment) near the seal portion 2 provided on the upper side. ), A notch 5 which is generally called a notch is provided. Although the notch 5 has a substantially V-shape, it may have a substantially U-shape or any other shape that allows the packaging bag to be easily torn.

Also, in the packaging bag of the present invention, it is preferable that the width of the seal portion 3 is narrower than the width of the seal portion 2. This is because if the peel strength of both the seal portion 2 and the seal portion 3 is such that they can be peeled off by the force of a human hand, the seal portion 3 can be peeled off more easily. In this embodiment, the width of the seal portion 2 is about 12 to 13% of the vertical length of the synthetic resin film 1 and about 11 to 12% of the horizontal length thereof, and the width of the seal portion 3 is about 9 to about the vertical length of the synthetic resin film 1. 10
%, And about 8 to 9% of the lateral length, but the present invention is not limited to these ratios. In this embodiment, the horizontal length of the synthetic resin film 1 is about 15% longer than the vertical length, but a quadrangle closer to a square makes it easier to hold when the packaging bag of the present invention is opened. preferable.

The packaging bag of the present invention configured as described above has the state shown in FIG. 1 to the state shown in FIG. 2, the state shown in FIG. 2 to the state shown in FIGS. It can be used in three states from the state shown to the state shown in FIGS.

That is, as shown in FIG. 2, from the notch 5 on both sides in the vicinity of the seal portion 2 provided on the side 1a of the synthetic resin film 1 toward the other notch 5, this packaging bag is formed. It can be used in the conventional state of tearing, opening the upper side and taking out with chopsticks.

Further, the end of the synthetic resin film 1 is pinched by inserting the fingertip of the hand into the non-sealing portion 4 of the packaging bag in the state shown in FIG. 2 and heat-sealed as shown in FIG. The seal portion 3 is torn, and as shown in FIG. 4, the three sides of the upper side, the side, and the lower side are opened and taken out with chopsticks or the like, which is used in a unique state of the packaging bag of the present invention. be able to.

The synthetic resin film 1 is prepared by inserting the fingertips of the hand into the non-sealing portion 4 of the packaging bag in the state shown in FIG.
The end portion of the bag is picked, the heat-sealed seal portion 3 is torn as shown in FIG. 5, and the two side portions of the side portion and the lower side portion are opened as shown in FIG. It can be used in a unique state of the packaging bag of the present invention, in which it is held in a cup shape and taken out with chopsticks or the like.

Therefore, in the packaging bag of the present invention, as shown in FIGS. 4 and 6, if the three side portions or the two side portions are opened, the opening portion becomes wider, and the two side portions are opened. Then, it becomes easier to hold the opened bag by hand.

[0024]

The packaging bag of the present invention is constructed as described above, and not only the upper side portion but also the adjacent two side portions can be opened, and further the three side portions can be opened if necessary. Therefore, even if foods such as kelp, boiled boiled beans, boiled beans, etc. are easily stored, the opening will be wide and chopsticks will be easy to insert into the bag, which will make the food easier to pick and open. The bag is easier to hold by hand,
These foods that are likely to vary can be easily taken out from the bag.
