Description

The present invention relates to a handle structure for a packaging bag, a packaging bag provided with the handle, and a method for manufacturing the handle structure.
More specifically, in the handle structure attached so as to form a handle at the opening edge of the side wall of the bag body, when the handle structure is held, the display unit printed on the handle structure is provided. This is related to the ink that does not peel off. Further, the present invention relates to a bag body in which the vicinity of the portion where the handle structure is attached is not easily torn.

  For example, as a simple container used as a shopping bag or the like, a packaging bag 9 with a handle made of a synthetic resin has been widely used (see, for example, FIG. 6). As such a packaging bag 9 with a handle, a handle component 91 that forms a handle is formed of a synthetic resin belt-like body, and both sides thereof are inserted into the bag body 90 to open the side walls 900, 900. Some are welded to the edge. Usually, an advertisement is provided on the side wall of the packaging bag 9 by printing. In recent years, advertisements on the packaging bag 9 are provided not only on the opposite side wall portions but also on the handle structure 91.

However, the packaging bag 9 described above has the following problems.
First, since the handle component 91 is held when the packaging bag 9 is carried, there is a problem that the ink constituting the advertisement is gradually peeled off by palm sweat or oil, and the appearance becomes unsightly. . In addition, the hand becomes dirty due to the ink peeling off.

  Further, in the case where the handle component 91 is welded and attached to the inside of the bag body 90, by holding the handle component 91, only this portion is inward of the welded portion 92 of the bag body 90. Since the bag body 90 is pulled in an oblique direction, the bag body 90 may be torn from the vicinity of the weld location 92 and torn (see FIG. 7). In particular, the above problem appears more prominently when an article is packed in a packaging bag in which gusset portions 901 and 901 are provided between the side wall portions 900 and 900 so that there is no gap.

An object of the present invention is to provide a handle structure that is attached to form a handle at the opening edge of the side wall of the bag body, and is provided by printing on the handle structure when the handle structure is held.

The packaging bag H includes a bag body 1 and handle components 2 and 2. Both the bag body 1 and the handle components 2 and 2 shown in the present embodiment are made of synthetic resin.

  The bag body 1 has a shape including side wall portions 10 and 10 facing each other, gusset portions 11 and 11 provided therebetween, and a bottom portion 12 at the bottom. The bag body 1 shown in the present embodiment is described by taking as an example one manufactured by a so-called bottom seal method in which the bottom is welded (sealed). However, this is not a limitation, and the packaging bag may be a bag manufactured by a so-called side seal method formed by welding the side portions.

  The handle structure 2 is provided on each of the side wall portions 10 and 10 facing each other. Each handle component 2 is formed in a band shape having a required length, and is attached by welding both ends to the opening edge of the side wall 10.

  The handle structure 2 will be described in detail. The handle structure 2 includes a sheet-like belt-like body 20 having a required length as a whole and an opaque belt-like body 21 formed in substantially the same shape as the belt-like body 20. The belt-like body 20 and the belt-like body 21 are constituent means constituting the handle construction body 2.

  Among these, on the back surface (inner surface) of the transparent belt-like body 20, a display unit 22 that is visible from the outside through the belt-like body 20 is provided. The display unit 22 is formed by printing and providing ink on the strip 20. Usually, an advertisement is displayed on the display unit 22. However, what is displayed on the display unit 22 is not limited to an advertisement, and for example, a sign (including a trademark) or a mark can be provided. Moreover, although the display part 22 is normally comprised by a character, a symbol, a figure (illustration) etc., this is not specifically limited, either. Furthermore, colors can be given to the display unit 22. Characters “Morofuji Inc.” are drawn on the display unit 22 shown in the present embodiment. In addition, since the whole strip | belt-shaped body 20 shown by this Embodiment is transparent, the see-through | perspective part in this case covers the whole.

  The belt-like body 20 and the belt-like body 21 are overlapped over the entire length so that the printed display portion 22 is provided inside. Further, the band-shaped body 20 and the band-shaped body 21 are formed of a square-point welded portion 23 (seal portion) on both edge sides extending in the length direction, except for both end portions welded to the opening edge of the side wall portion 10. ) Are provided at a predetermined interval and integrated.

  The handle component body 2 is provided with the end portions of the belt-like body 20 and the belt-like body 21 on the outer side and the inner side of the side wall portion 10 of the bag body 1, and the belt-like body 20, the belt-like body 21 and the bag with the side wall portion 10 interposed therebetween. It is welded and attached so that the main body 1 is integrated. The code | symbol 3 has shown the welding part which attaches the strip | belt-shaped body 20 and the strip | belt-shaped body 21, and the bag main body 1 so that it may be united. In the present embodiment, the transparent belt-like body 20 is provided outside the bag body 1. However, this is not a limitation, and the belt-like body 21 can be disposed outside the bag body 1.

(Work)
With reference to FIG. 1 thru | or FIG. 3, the effect | action of the packaging bag H shown in this Embodiment is demonstrated.
The handle structure 2 is formed by superimposing the band-shaped body 20 and the band-shaped body 21 so that the printed display section 22 is provided inside, so that the display section 22 cannot be directly touched. Therefore, even when the handle structure 2 is held, the ink of the display unit 22 does not peel off and the appearance is not unsightly. Further, since the ink does not peel off, the hand held by the handle components 2 and 2 is not soiled.

  Further, the handle structure 2 is provided with the end portions of the band-like body 20 and the band-like body 21 on the outer side and the inner side of the side wall part 10 of the bag body 1, and the band-like body 20 and the band-like body 21 with the side wall part 10 sandwiched therebetween. And the bag body 1 are welded so as to be integrated with each other. When the handle structure 2 is held, the attachment position of the handle structure 2 is the inner side from both the inner surface and the outer surface of the bag body 1. It is pulled in the diagonal direction. In this case, the vicinity of the attachment location of the handle structure 2 and the bag body 1 is hardly broken.

  In addition, the handle structure 2 shown in the present embodiment is configured so that the end portions of the band-shaped body 20 and the band-shaped body 21 are provided on the outer side and the inner side of the side wall portion 10 of the bag body 1 and the side wall portion 10 is sandwiched therebetween. Although it attached to the main body 1, the attachment structure of the handle structure 2 is not limited to this. For example, as shown in FIG. 4, the handle structure 2 can be attached by providing both of the end portions of the band-like body 20 and the band-like body 21 inside the side wall portion, or as shown in FIG. 5. It is also possible to attach both of the end portions of the belt-like body 21 to the outside of the side walls.

  In the present embodiment, the handle structure 2 is shown in which the display unit 22 is provided on the back surface of the transparent belt-shaped body 20, but this is not limited, and the handle structure 2 is viewed from the outside through the see-through unit. If possible, the display unit 22 can be provided on the belt-like body 21, or can be provided on both the belt-like body 20 and the belt-like body 21. In particular, in the case where the display unit is provided on both the band-shaped body 20 and the band-shaped body 21, many types of handle structures can be easily formed by combining different patterns of the display unit.

  In the present embodiment, the handle structure 2 is formed of a synthetic resin, but the material forming the handle structure is not particularly limited. For example, the handle structure 2 is formed of paper or a composite of synthetic resin and paper. Can be used. In addition, the handle structure can be formed by overlapping strips of different materials.

  In the present embodiment, the handle structure 2 has been formed by superimposing the band-shaped body 20 and the band-shaped body 21, but this is not a limitation. For example, the handle structure includes more band-shaped bodies. Can also be formed by superimposing (three or more layers). In this case, if it can be visually recognized from the outside, the display portion can be provided on a belt-like body provided therebetween.

  In the present embodiment, the band-shaped body 20 forming the handle structure 2 is a transparent body that is transparent as a whole, but this is not a limitation, and the transparent section that allows the display section to be visually recognized from the outside. For example, it suffices to be provided only at least in a portion where the display portion is provided. Moreover, you may provide the strip | belt-shaped body to overlap only in the part in which a display part is provided instead of the whole handle structure.

  In the present embodiment, the entire belt-like body 20 is transparent, but this is not a limitation, and the see-through portion can be made semitransparent as long as the display portion can be visually recognized from the outside.

In the present embodiment, the handle structure 2 is shown as being formed by providing square-point welded portions (seal portions) on both edge sides extending in the length direction, but this is not a limitation. For example, the welded portion can be round or triangular. Furthermore, the welded portion can be formed in a line shape instead of a dot shape. When it is linear, it can also be provided over the entire length in the length direction.
In addition, as the handle structure, for example, a structure in which strips are overlapped by adhesion, adhesion, pressure bonding, sewing, fixing by a stapler, or the like can be used.

  In the present embodiment, the handle structure 2 has been formed by superposing separate band-shaped bodies. However, the handle structure is not limited to this, for example, a wide band-shaped having a required length. It is also possible to use a belt that has a body and is folded in the width direction so that a folding line is formed in the length direction.

Although the packaging bag shown in the embodiment has been provided with the gusset portions 11 and 11 and the bottom portion 12, this is not limited, and the packaging bag does not have a gusset portion and does not have a bottom bottom portion. The thing of the form which is not equipped with both of these can also be used.
The bag body may be of a type formed by folding the opening edge side inward or outward. In the case of such a bag body, the overlapped portion may be welded or may not be welded.

  In the embodiment, the welded portion 3 has an elliptical shape. However, the shape of the welded portion is not particularly limited, and may be a polygonal shape such as a circular shape or a square shape. . Further, the welding can be performed only on the outer edge portion of the welding portion 3.

  The terms and expressions used in this specification are merely explanatory and are not limiting at all, and exclude terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to do. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
