[0009]

[Action]

 The packaging bag for sandwiches and the like of the present invention is provided along the direction of tearing in the opening direction from the projecting piece 7 to the bag body 6 with the knob piece 11 and the center piece 17 of the notch 16 which are the starting points of tearing. Since the unsealing tape 12 provided serves as a guide and guides smoothly, the consumer can very easily and surely perform the unsealing operation of the packaging bag.

[0010]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 1 and a sectional view taken along line AA (FIG. 2) of the present invention, a packaging bag for sandwiches and the like has a pair of packaging films (for convenience, these two films have a substantially trapezoidal shape). Rum is referred to as front film 1 and back film 2), and both side edges 3 and 3 are heat-welded, and one end side (the long lower side of the trapezoid) is the opening 4 and the other end side (the short lower side of the trapezoid). The seal body 5 is composed of a bag body 6 and projecting pieces 7 and 8 integrally extending from the seal portion 5 to the front film 1 and the back film 2, respectively. is there.

A uniaxially oriented polypropylene (CPP) film, low density polyethylene (LDPE), high density polyethylene (HDPE) or the like is used as a film forming the bag body 6 and the protruding pieces 7 and 8. It has the function of preventing evaporation of water and preventing dust.

The seal portion 5 is formed so that the two films 2 and 3 can be brought into contact with and separated from each other by weakly heat-sealing one end of the front film 1 and the back film 2 on the tapered side, and The projecting pieces 7 and 8 are heat-welded and integrated at the peripheral edge portion 9 thereof, and can form a stable and stable gripping portion.

At a substantially central portion of the protruding piece 7 on the side of the front film 1, a tongue-like shape formed by punching a cut line 10 in a horseshoe shape, a substantially U shape, an M shape, or the like. A tab 11 is provided, which serves as a starting point for tearing when the tab 11 is opened from the protruding piece 7 toward the bag body 6.

An unsealing tape 12 having a constant width is attached in the unsealing direction of the inner surface center portion of the projecting piece 7 to the front film 1, and the unsealing tape 12 unseals the bag body 6. It can serve as a directional guide.

An explanation will be given of a case in which an object to be stored such as a sandwich is housed and sealed in the packaging bag configured as described above, and then the sealed bag is opened and the housed sandwich is taken out.

First, as shown in FIG. 3, the opening 4 of the bag body 6 is opened to store the sandwich 13 in the bag body 6, and the bag body 6 is fitted to the shape of the sandwich 13. Fold it (see dashed line in Figure 1).

Next, the extending portion 14 of the bag body 1 protruding from the sandwich 13 accommodated is folded inward (see the chain line in FIG. 3), and then the extending portion 14 is folded, The opening 4 on one end side of the bag body 1 accommodating the sandwich 13 can be sealed by sticking a sealing / unsealing tape (not shown) or the like (see FIG. 4).

Next, the case of opening the packaging bag will be described.

First, as shown in FIG. 5, both projecting pieces 7 and 8 integrally extended from the seal portion 5 are grasped by one hand (finger), and the cut line is formed by the other hand (finger). When the gripping piece 11 formed via 10 is gripped and pulled toward the opening direction of the bag body 6 (arrow E), the front film 1 forming the bag body 6 tears along the tearing direction of the film. It will be refused and opened.

At this time, the unsealing tape 12 serves as a guide, and smoothly ruptures in a band of a constant width until reaching the opening 4, and the tearing line comes close to one point, and the tearing process is in progress. The opening operation of the packaging bag can be carried out extremely easily and surely without being cut by.

Further, since both projecting pieces 7 and 8 have an appropriate waist, they can be held in a stable state, and the packaging bag body can be easily torn and opened.

The opening tape 12 is not limited to the tape having the length from the tip 15 of the projecting piece 7 to the tip of the bag body 6 on the side of the opening 4 as described above. For example, as shown in FIG. 6 to FIG. 8, a piece pasted from the front of the knob 11 (the side near the seal part 5) to the tip of the opening 4 side, or from the front of the knob 11 to the opening 4 side. Even if it is attached halfway, it is sufficient if it is long enough to be used as a guide.

Further, the unsealing tape 12 may be adhered to the surface film 1 on the entire surface thereof, or may be adhered to the surface film 1 only at both longitudinal edges of the tape.

Further, in the above-described embodiment, the tearing starting point for opening is the knob piece 11 formed through the notch line 10. However, as shown in FIGS. 8 and 9, the tip portion 15 of the protruding piece 7 is By notching the notches 16 and 16 at symmetrical positions, the center piece 17 between them plays the same role as the knob piece 11, and the packaging bag can be opened simply by pulling the center piece 17 in the opening direction. Becomes

As described above, the gripping piece 11 and the cutouts 16 and 16 formed by piercing the cut line 10 are provided not on the bag body 6 side but on the protruding pieces 7 and 8 side via the seal portion 5. Therefore, the object to be stored such as the sandwich 13 stored in the bag body 6 is not exposed from the picking piece 11 and the notches 16 and 16, and it can be a very hygienic packaging bag.

It should be noted that the thermal welding at the peripheral edge portion 9 between the projecting pieces 7 and 8 is not essential, and, for example, as shown in FIG. 6, even if only the tip portion 15 thereof is welded, The entire protruding pieces 7 and 8 may be welded except for the vicinity of the picking piece 11. Further, as shown in FIG. 7, only the seal portion 5 may be heat-welded and the protruding pieces 7 and 8 may not be welded at all. In short, the protruding pieces 7 and 8 may be welded together. It suffices if a stable grip portion can be obtained when opening.

In particular, as shown in FIGS. 8 and 9, if the cuts 16 and 16 are the starting points, it is preferable that the protruding pieces 7 and 8 are not welded to each other. The welding position of the projecting pieces 7 and 8 may be appropriately selected depending on the length of the tape 12 for use, the shape of the cleavage starting point, and the like.

Further, in the above-mentioned embodiment, the tip portions 15 of both the projecting pieces 7 and 8 are formed so as to be located on the same line, but the two projecting pieces 7 and 8 need not necessarily be located on the same line. Alternatively, the end of one protruding piece may be formed to be located above the end of the other protruding piece, and even in this case, there is no problem with the ease of holding the knob 11. Moreover, there is no obstacle to the integration of the two protruding pieces 7 and 8.

Further, the tape 12 for opening is not only attached to the inner surface of the surface film 1 as in the above-mentioned embodiment, but also to the tape 12 as shown in FIGS. 6 to 9. The opening tape 12 may be attached to the inner surface or the outer surface of the surface film 1 as long as it is a short piece or a material starting from the notches 16 and 16.

Further, the specific size such as the width of the unsealing tape 12 is not limited by any means, and the shape and material of the tape 12 and the kind of adhesive applied to the adhesive surface, The adhesive strength and the like are also not limited.

In the above embodiment, the sandwich 13 is applied as the item to be stored, but the type of the item to be stored is not limited to the sandwich 13, and for example, foods with extremely weak shape retention, cooked rice foods, etc. However, the type etc. are not limited by any means.

Further, in the above-mentioned embodiment, the bag body 6 is formed in a substantially trapezoidal shape so as to suit the form of the sandwich 13, but the shape of the bag body 6 is not limited to this. However, it can be arbitrarily changed according to the type of food or the like to be packaged, and the point is that it has a predetermined opening 4 and can fold the opening 4 to store an object to be stored inside. If formed, the material, shape, size, etc. of the packaging bag are not limited.
