Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag for packaging thin plate-shaped articles such as gold seals and various sheets.

[0002]

[Prior art]

 For example, a thin plate-like article such as a gold seal is displayed in a store and sold in a state of being housed in a transparent plastic film packaging bag. As a method of displaying such a packaging bag containing an article, there are a case where the packaging bag containing the article is laid flat as it is and a case where the packaging bag containing the article is hung from a hanging rod (display hanger).

Among known packaging bags of this type, there are those which can be adopted by selecting the above two display methods as shown in, for example, FIGS. 8 and 9 (utility model No. 1). 3006 372). The known packaging bag shown in FIGS. 8 and 9 has an upper end on one surface of the bag body 1 which is folded back onto the bag opening 2 so as to integrally connect a lid 3 for covering the bag opening 2. A hanging piece 5 defined by a substantially U-shaped slit 4 is formed on the lid 3. The slit 4 is formed in a continuous state. A hanging hole 6 is formed in the center of the hanging piece 5. An adhesive 12 is applied to a position near the upper end of the lid portion 3, and the adhesive applied portion is covered with a release sheet 11.

In this known packaging bag, the thin plate-like article 10 is housed in the bag body 1, the release sheet 11 is peeled off, and the lid portion 3 is folded along the fold line BB as shown by an arrow A (FIG. 8). The article 10 can be enclosed and packaged by folding back to the bag opening portion 2 side and adhering the application portion of the adhesive 12 to the outer surface of the bag body 1. Further, when the lid 3 is folded back to cover the bag opening 2, when the packaging bag containing the articles is displayed in a flat state, the hanging piece 5 is also folded back together with the lid 3, while the hanging rod 20 When hanging and displaying, the lid 3 is folded back with the hanging piece 5 left. When the lid portion 3 is folded back with the hanging piece 5 left (that is, the hanging piece 5 is projected upward), as shown in FIG. The packaging bag containing the article can be displayed through the hanging rod 20.

[0005]

[Problems to be solved by the device]

 By the way, in the known packaging bag shown in FIG. 8 and FIG. 9, the above two display methods can be selected and adopted. However, when the hanging piece 5 is left and the lid portion 3 is folded back. Has a hole 15 in the portion of the lid portion 3 where the hanging piece 5 is cut out (range of length L in FIG. 8), and the hole 15 portion in the bag opening portion 2 is not covered. Therefore, when the hanging piece 5 is hung by the hanging rod 20 and displayed as shown in FIG. 9, there is a disadvantage that dust enters the bag body 1 through the hole 15 portion.

Further, since the upper portion and both side portions of the hanging piece 5 are completely separated from the lid portion 3 by the continuous slits 4, the hanging piece 5 may be attached to the lid portion 3 by a flap. When the lid 3 and the hanging piece 5 are folded back together, the hanging piece 5 part may inadvertently float up. As described above, when the hanging piece 5 floats up, there is a problem that the appearance of the hanging piece 5 part is deteriorated.

In view of the above-mentioned problems of the known packaging bag, the present invention selects and employs a method of flatly placing the article-containing packaging bag as it is and a method of hanging the hanging bag from a hanging rod when displaying the packaging bag. In the packaging bag to be obtained, whichever display method is adopted, the bag opening portion of the bag body can be surely covered, and the hanging piece portion can be prevented from flickering. Is intended to provide.

[0008]

[Means for Solving the Problems]

 The packaging bag of the present invention has the following structure as means for solving the above-mentioned problems.

That is, as shown in FIGS. 1 to 7, the packaging bag of the present invention is formed by folding back the bag opening 2 on the upper end of one surface of the bag body 1 having the bag opening 2 on the upper side. The lid 3 that covers the bag opening 3 is continuous. On a part of the lid portion 3, a hanging piece 5 defined by a slit 4 having a substantially inverted U shape is formed. Further, a hanging hole 6 is formed in the substantially hanging portion 5 (inside the slit section). Further, an inner lid 7 that can cover at least a portion of the bag opening 2 corresponding to the hanging piece 5 when the lid 3 is folded back to cover the bag opening 2 is provided at a position near the bag opening 2 in the lid 3. It is installed.

The packaging bag of the present invention is preferably formed entirely of a transparent plastic film. When this packaging bag is used, for example, as a gold enclosure, the size of the bag body 1 is made slightly larger than the outer shape of the gold seal to be packaged. The lid portion 3 extends upward (outward) from the bag opening portion 2 by a predetermined length. Further, it is preferable that the adhesive 12 is applied to a position near the upper end of the lid portion 3 and the release sheet 11 is attached to the adhesive applied portion. The hanging piece 5 defined / formed on the lid portion 3 can be formed in an appropriate size. Further, both left and right base end portions of the slit 4 partitioning the hanging piece 5 may be brought close to the vicinity of the folding line of the lid portion 3 (near the bag opening portion 2). The inner lid 7 can be adhered to an appropriate place on the surface of the lid portion 3 on the bag opening 2 side, but the inner lid 7 is not adhered to the hanging piece 7.

Further, in the present invention, a small width continuous portion 4a for connecting the lid portion 3 and the hanging piece 5 to each other in a very small range (for example, a width of about 1 mm) is provided in the slit 4 portion which defines the hanging piece 5. Can be set up. In this case, the narrow width continuous portion 4a is made continuous so that the hanging piece 5 can be easily torn into pieces simply by pushing the hanging piece 5 into the lid portion 3. Further, the narrow width continuous portion 4a may be provided only at one location on the upper end portion (the middle portion of the entire length of the slit) of the hanging piece 5, or may be provided at two to three locations with a predetermined interval.

Further, in the present invention, the inner lid 7 can be folded back upward at the position closest to the bag opening 2. That is, when the lid 3 is extended upward (opened state shown in FIGS. 1, 2, and 6), the lower end of the inner lid 7 is positioned slightly above the upper edge of the bag opening 2. When the lid portion 3 is folded back toward the bag opening portion 2 side (closed lid state shown in FIGS. 4, 5, and 7), the lid portion 3 and the inner lid 7 cover the bag opening portion 2. Has become.

Further, in the present invention, as shown in FIGS. 1 to 5, the inner lid 7 is formed to have the same width as the left and right width of the lid portion 3, and the left and right end portions 7a of the inner lid 7 are 7a can be attached to the lid 3 as shown in FIG. The left and right end portions 7a, 7a of the inner lid 7 are welded to the lid portion 3 by heating and welding the left and right end portions 7a, 7a to each other by using a process of thermally cutting both side edges of the bag during bag formation. It is better to let them do it.

Further, in the present invention, as shown in FIGS. 6 to 7, the inner lid 7 has a lateral length slightly larger than a lateral width of the hanging piece 5 at a position corresponding to the hanging piece 5. May be formed. In this case, a part of the inner lid 7 (a portion 7b in FIGS. 6 to 7) is adhered to the lid portion 3.

2, FIG. 3, FIG. 5, and FIG. 9, the thickness of the bag material (including the release sheet and the inner lid) is shown thick for convenience, but the bag material is actually It is a very thin film.

[0016]

[Action]

 In the packaging bag of the present invention, in order to store the thin plate-shaped article (for example, a gold seal) 10 in the bag body 1, the thin plate-shaped article 10 is placed in the bag opening 2 while the lid 3 is extended upward. However, in the case where the inner lid 7 is folded upward at the position closest to the bag opening 2 as shown in FIG. 2, the lower end of the inner lid 7 is located above the upper end of the bag opening 2. The inner lid 7 does not hinder the accommodation of the thin plate-shaped article 10 in the bag body 1.

In the packaging bag of the present invention, the thin plate-like article 10 is housed in the bag body 1, and the bag opening 2 is covered with the lid 3, which is used. The inner lid 7 is also covered on the bag opening 2 when folded back.

By the way, when the packaging bag containing the articles is displayed in a flat state, if the hanging piece 5 is connected to the lid portion 3 by the narrow width continuous portion 4a, the narrow width continuous portion 4a should not be cut. Then, the lid portion 3 and the hanging piece 5 are folded back to bond the lid portion 3 to the outer surface of the bag body 1. In the case where the hanging piece 5 and the lid portion 3 are connected by the narrow width continuous portion 4a like this, since the hanging piece 5 is integrated with the lid portion 3, the hanging piece 5 as well as the lid portion 3 is formed. The bag body 1 is joined (fitted) to the outer surface of the bag body 1, so that the hanging piece 5 does not fly (lift) from the lid portion 3.

On the other hand, when the packaging bag containing the articles is hung on the hanging rod 20 and is displayed, for example, as shown in FIGS. It is folded back to the side and the lid part 3 is adhered to the outer surface of the bag body 1. In this case, in the case where the hanging piece 5 is connected to the lid portion 3 by the small width continuous portion 4a, after the small width continuous portion 4a is torn, the hanging piece 5 is left and the lid portion 3 is removed. Turn back. When only the lid portion 3 is folded back in this manner, the hanging piece 5 projects above the bag body 1, and the hanging hole 6 of the hanging piece 5 is hooked on the hanging rod 20 so that the article The packaging bag can be displayed in a suspended state. By the way, when the lid 3 is folded back with the hanging piece 5 left, a hole 15 is formed at a position corresponding to the hanging piece 5 on the lid 3 as shown in FIGS. 4 and 5 or 7. The inner lid 7 is located below the hole 15. Therefore, the portion corresponding to the hole 15 in the bag opening 2 is closed by the inner lid 7, and dust does not enter the bag opening 2 through the hole 15.

[0020]

[Effect of device]

 As described above, in the packaging bag of the present invention, since the inner lid 7 is provided separately from the lid portion 3, the hanging piece 5 is defined and formed in the lid portion, and the hanging piece 5 is left and the lid portion 3 is left. Even when only the hook is folded back (a hole 15 is formed in a portion of the lid 3 corresponding to the hanging piece 5), the bag opening 2 of the portion corresponding to the hanging piece 5 is covered with the inner lid 7. Like Therefore, there is an effect that dust does not enter the bag opening 2 through the hole 15 of the portion corresponding to the hanging piece 5 in the lid 3, and a packaging bag having a high commercial value can be provided.

Further, in the case where the lid portion 3 and the hanging piece 5 are connected by the small width continuous portion 4a, the hanging piece 5 is integrated with the lid portion 3, and therefore the hanging piece 5 is folded back together with the lid portion 3. In this case, the lid 3 and the hanging piece 5 are both joined (fitted) to the outer surface of the bag body 1, and the hanging piece 5 is visibly attached (floating) to the lid 3 and looks good. This has the effect of eliminating the problem of poor performance.

Further, in the case where the inner lid 7 is folded back upward at the position closest to the bag opening portion 2, when the thin plate-like article 10 is stored in the bag body 1 from the bag opening portion 2, the inner lid 7 interferes. Therefore, even if the inner lid 7 is provided, the work of accommodating the thin plate-shaped article 10 can be easily performed.

Further, in the case where the inner lid 7 has the same width as the left and right width of the lid portion 3 and each of the left and right end portions 7 a, 7 a of the inner lid 7 is adhered to the lid portion 3, the inner lid 7 is attached to the bag. The inner lid 7 can be attached easily by heat bonding during the molding process. That is, both sides of the bag body 1 are adhered to each other by heat cutting of the packaging bag, but the left and right ends 7a, 7a of the inner lid 7 are also adhered to the lid portion 3 at the same time as the steps of cutting and adhering both sides of the bag body. The effect is that it can be done.

Further, when the inner lid 7 is formed to have a lateral length slightly larger than the lateral width of the hanging piece 5, there is an effect that the material of the inner lid 7 can be reduced.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIGS. 1 to 5 show a first embodiment, and FIGS. 6 and 7 show a packaging bag according to a second embodiment. ing. The packaging bag of each of these embodiments is for accommodating a thin plate-like article 10 such as a gold seal, and is therefore entirely formed of a transparent plastic film. The bag body 1 is formed to have a size that is slightly larger than the outer shape of a thin plate-shaped article (for example, a gold seal) 10 accommodated inside the bag body 1. For example, in the case of a packaging bag for gold sealing, the size of the bag body 1 is, for example, 12 cm in width and 19 cm in length.

The packaging bag of the first embodiment shown in FIGS. 1 to 5 has a bag body 2 having a bag opening 2 on the upper side. The lid 3 covering 3 is continuous. The lid 3 extends upward from the bag opening 2 by a predetermined length (for example, about 4 cm). At a position near the upper end of the lid portion 3, an adhesive 12 is applied by a predetermined width (for example, a width of about 1 cm), and a peeling sheet 11 is attached to the adhesive applied portion.

On a part of the lid portion 3, a hanging piece 5 defined by a slit 4 having a substantially inverted U shape is formed. The left and right base ends of the slit 4 that defines the hanging piece 5 are close to the vicinity of the folding line of the lid 3 (near the bag opening 2). In addition, the slit 4 portion is provided with a small width continuous portion 4a which connects the lid portion 3 and the hanging piece 5 to each other only at a small range at one of the left and right intermediate positions. The small-width continuous portion 4a is formed within a range (for example, a width of 1 mm attitude) in which the hanging piece 5 can be easily torn into pieces by simply pushing the hanging piece 5 into the lid portion 3. The narrow width continuous portion 4a may be provided at only one place as shown in the illustrated example, but may be provided at two or three places with a predetermined interval in other embodiments.

A hanging hole 6 is formed in a substantially central portion of the hanging piece 5. The hanging hole 6 is for inserting a hanging bar (display hanger) 20 for display as shown in FIG. 5, and has a hole diameter of, for example, about 8 mm.

Further, an inner lid 7 that can cover the bag opening 2 when the lid 3 is folded back to cover the bag opening 2 is attached to the lid 3 at a position closest to the bag opening 2. In the first embodiment, the inner lid 7 has the same width as the left-right width of the lid portion 3 and is folded upward at the position closest to the bag opening portion 2. As shown in FIG. 3, the inner lid 7 has the left and right end portions 7a, 7a (two of which are folded back) are adhered to the lid portion 3, respectively. The left and right end portions 7a, 7a of the inner lid 7 are adhered to each other by heating and welding at the same time when heat cutting during bag formation. The inner lid 7 is not adhered to the hanging piece 7.

Further, as shown in FIGS. 1 and 2, when the lid 3 is extended above the bag body 1 (opened state), the lower end (folded portion) of the inner lid 7 is the bag. It is located slightly above the upper edge of the opening 2, and when the lid 3 is folded back toward the bag opening 2 side (closed state) as shown in FIGS. The part 3 and the inner lid 7 cover the bag opening 2.

The packaging bag of the first embodiment is used as follows. First, in order to store a thin plate-like article (for example, a gold seal) 10 in the bag body 1, as shown in FIGS. 1 and 2, the thin plate-like article 10 is opened with the lid portion 3 extended upward. Insert from the bag opening 2. At that time, the inner lid 7 is folded back upward at the position closest to the bag opening 2 (the inner lid 7 is located above the upper end of the bag opening 2), and the left and right end portions of the inner lid 7 are also folded. Since 7a, 7a are respectively adhered to the inner lid 3, the upwardly folded portions of the inner lid 7 do not inadvertently close the opening 2. Therefore, the inner lid 7 does not get in the way when the thin plate-shaped article 10 is stored. In this packaging bag, the thin plate-like article 10 is housed in the bag body 1 and the bag opening 2 is covered with the lid 3, which is used by folding the lid 3 onto the bag opening 2. The inner lid 7 is also covered on the bag opening 2 when it is opened.

By the way, when the packaging bag containing the articles is displayed in a flat state, the hanging portion 5 is connected to the lid portion 3 at the narrow width continuous portion 4 a, and the lid portion 3 and the hanging portion 5 are connected. And the lid 3 is adhered to the outer surface of the bag body 1 (the release sheet 11 is peeled off and the adhesive 12 applied portion is adhered to the outer surface of the bag body). In the case where the hanging piece 5 and the lid portion 3 are connected by the small-width continuous portion 4a as described above, since the hanging piece 5 is integrated with the lid portion 3, both the lid portion 3 and the hanging piece 5 are integrated. By joining (fitting) to the outer surface of the bag body 1, the hanging piece 5 does not fly (lift) with respect to the lid portion 3.

On the other hand, when the packaging bag containing the articles is hung on the hanging rod 20 to be displayed, as shown in FIGS. 4 and 5, only the lid 3 is left on the bag opening 2 side while the hanging piece 5 is left. It is folded back and the lid 3 is adhered to the outer surface of the bag body 1. In this case, the lid portion 3 is folded back after the small width continuous portion 4a is torn. When only the lid 3 is folded back in this way, the hanging piece 5 projects above the bag body 1, and the hanging hole 6 of the hanging piece 5 is hooked on the hanging rod 20 to form this article-containing package. The bag can be displayed in a suspended state. By the way, when the lid portion 3 is folded back with the hanging piece 5 left, as shown in FIGS. 4 and 5, a hole 15 is formed at a position corresponding to the hanging piece 5 in the lid portion 3, An inner lid 7 is located below the hole 15. Therefore, the portion of the bag opening 2 corresponding to the hole 15 is closed by the inner lid 7, and it is possible to reliably prevent dust from entering the bag opening 2 through the hole 15.

In the packaging bag of the second embodiment shown in FIGS. 6 to 7, the inner lid 7 has a left and right length that is slightly larger than the left and right width of the hanging piece 5 at the position corresponding to the hanging piece 5. Is formed. In this case as well, the inner lid 7 is attached in a state of being folded back upward at the position immediately adjacent to the bag opening 2. Further, in this second embodiment, a part of the inner lid 7 (reference numeral 7b portion) is adhered to the lid portion 3. The other construction of the second embodiment is similar to that of the first embodiment. Also in the packaging bag of the second embodiment, as shown in FIG. 7, when the lid 3 is folded back with the hanging piece 5 left, it is formed in the portion of the lid 3 to which the hanging piece 5 corresponds. The hole 15 to be opened can be closed by the inner lid 7.
