Description

The present invention relates to a packaging bag with a handle suitable for containing various contents such as liquids, powders, solids, and mixtures thereof, and more specifically, the handle portion has excellent strength. The present invention relates to a packaging bag with a handle that can maintain a form suitable for insertion of a finger and is excellent in handleability during carrying.
In addition, the present invention is a packaging with a handle that can smoothly perform display work in a store of packaging bags as products containing contents, take-out of goods by a customer, cash registering work, pouring of contents, etc. The present invention relates to a packaging bag with a handle that is excellent in sales efficiency and convenience.

  Conventionally, flexible bags 50 and 60 as shown in FIGS. 16A and 16B have been proposed as packaging bags with handles (Patent Document 1).

  A flexible bag (soft self-supporting bag) 50 shown in FIG. 16A joins the upper and side edges of the front and back body sheet 51 by heat-sealing or the like, The peripheral edge of the bottom sheet is joined to the edge by heat fusion or the like.

The conventional flexible bag 50 includes a pour spout 53 at the center of the upper edge joint 52, and overhangs 54 at both ends of the upper edge joint 52.
And both the overhang | projection parts 54 are equipped with the round hole-shaped finger hook part 55, By pouring a finger on these finger hook parts 55, the content is poured out from the spout provided in the spout planned part 53 In doing so, the two overhanging portions 54 can be drawn together to open the spout to facilitate the pouring of the contents.

  However, the round hole-like finger hook portion 55 provided in the conventional flexible bag 50 is not intended to be inserted with a finger to carry the flexible bag 50 in the first place. It cannot be suitably used as a handle for carrying the flexible bag 50.

  Furthermore, when the handle is formed by a method of providing a hole or notch on the surface of the film as in the conventional flexible bag 50, there is a problem that the strength around the hole or notch may be reduced.

  Also, the flexible bag 60 shown in FIG. 16 (B) has two body sheets 61 that extend from the both ends of the upper edge joint portion 62 and constitute the overhang portion 63. Only the extended outer end portion of the non-joining portion 65 is a joining portion 64, and the other portion is a non-joining portion 65, so that the hollow portion sandwiched by the two body sheets 61 of the non-joining portion 65 is the band-shaped finger hook portion 66. It is.

  In this conventional flexible bag 60, the surface of the film is not provided with holes or cuts to form the finger hook portion 66. The reason for the provision of the finger hook portion 66 is that the flexible bag When the contents are poured out from the spout provided in the spout planned portion 67 by putting the finger on the finger rest portion 66 in the same manner as the 50 finger rest portion 55, the both overhang portions 63 are attracted to each other. This is to make it easier to pour the contents by opening.

  Therefore, also in this conventional flexible bag 60, like the conventional flexible bag 50, the finger hook portion 66 is configured with the intention of inserting a finger to carry the flexible bag 50. Instead, in the state in which the contents are put, the front and rear films constituting the finger rest 66 are in close contact with each other, and the finger cannot be smoothly inserted into the finger rest 66.

  For the reasons described above, even in the conventional flexible bag 60, the finger hook portion 66 cannot be suitably used as a handle for carrying the flexible bag 60 containing the contents.

  That is, in these conventional flexible bags 50 and 60, it is completely considered that the round hole-like finger hook portion 55 and the band-like finger hook portion 66 are used when carrying the flexible bags 50 and 60 filled with the contents. It wasn't. Moreover, it was not comprised so that a several finger could be smoothly inserted in the one round hole-like finger hook part 55 and the finger hook part 66. FIG.
