Description

[Technical field]

[0001] The present invention relates to a packaging bag for containing an item. [Background technology]

[0002] Conventionally, packaging bags for containing articles have been known that are made by forming a sheet material such as a plastic film into a bag shape. For example, a packaging bag is known that includes a back-attached portion formed by overlapping a pair of side ends extending in one direction of the sheet material to form a cylindrical shape, and sealing the pair of side ends, and a pair of closed ends formed by closing both ends of a cylindrical region of the sheet material, and a storage portion for storing an article is formed between the pair of closed ends.

[0003] Incidentally, such packaging bags may be displayed in stores while being hung from a rod-shaped member. For this reason, the packaging bag is formed with a hanging through-portion that is formed so as to penetrate one of a pair of closed ends and through which a rod-shaped member is inserted (see Patent Document 1). The packaging bag is configured to be able to be hung from a rod-shaped member by inserting the rod-shaped member through the hanging through-portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 08-334869 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the method of displaying packaging bags by hanging them as described above, when multiple packaging bags are hung from a single rod-shaped member, the packaging bags overlap each other, making it difficult to view any packaging bags other than the one located closest to the front.

[0006] Therefore, an object of the present invention is to provide a packaging bag that can make multiple packaging bags containing items easily visible when the multiple packaging bags are displayed in a storefront or the like. [Means for solving the problem]

[0007] The packaging bag of the present invention is formed using a sheet material and has a storage section for storing an item, and a first extending section and a second extending section extending in different directions from the storage section, wherein the first extending section has a through portion that penetrates the first extending section, and the second extending section has an insertion portion that can be inserted into the through portion of the first extending section, and is configured so that the through portion and the insertion portion engage in the pulling-out direction when the insertion portion provided on the second extending section of one packaging bag is inserted into the through portion provided on the first extending section of the other packaging bag and then pulled out.

[0008] According to this configuration, the insertion portion of the second extending portion of one packaging bag is inserted into the penetration portion of the first extending portion of the other packaging bag, and the penetration portion and the insertion portion are configured to engage with each other in a direction in which the insertion portion is pulled out from the penetration portion of the first extending portion of the other packaging bag. This allows multiple packaging bags to be connected in the planar direction for display, making it easier to view the multiple packaging bags.

[0009] It is preferable that the insertion portion has two convex portions formed at opposing positions in a cross direction that intersects the withdrawal direction so as to be convex in the cross direction, and that the length between the tips of the two convex portions in the cross direction is longer than the length of the penetrating portion in the cross direction.

[0010] According to this configuration, the insertion portion includes two convex portions formed at opposing positions in a cross direction intersecting the pull-out direction so as to be convex in the cross direction. The length between the tips of the two convex portions in the cross direction is longer than the length of the penetrating portion in the cross direction. This makes it easier for the two convex portions to be hooked onto the inner edge of the penetrating portion in the direction in which the insertion portion is pulled out from the state in which the insertion portion is inserted into the penetrating portion. This makes it possible to maintain a good connection state between the packaging bags.

[0011] The through portion is composed of a cut line formed by cutting the first extension portion linearly, and the cut line is formed in a C-shape that opens toward the pulling-out direction, and it is preferable that the length between the tips of the two convex portions in the intersecting direction is configured to be longer than the distance between both ends of the cut line in the intersecting direction.

[0012] According to this configuration, the through-hole is composed of a cut line formed by cutting the first extending portion linearly. The cut line is formed in a C-shape that opens toward the pull-out direction. The length between the tips of the two convex portions in the cross direction is configured to be longer than the distance between both ends of the cut line in the cross direction. This makes it easier for the two convex portions to be hooked onto the inner edge of the through-hole near both ends of the cut line in the direction in which the insertion portion is pulled out from the state in which the insertion portion is inserted into the through-hole. This makes it possible to better maintain the connection state between the packaging bags. Effect of the Invention

[0013] As described above, according to the present invention, when a plurality of packaging bags containing articles are displayed in a storefront or the like, the plurality of packaging bags can be easily viewed. [Brief description of the drawings]

[Diagram 5] FIG. 11 is a front view showing an outline of a packaging bag according to still another embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A packaging bag 1 according to one embodiment of the present invention will be described below with reference to Fig. 1. In the following drawings, the same or corresponding parts are given the same reference characters and their description will not be repeated.

[0016] The packaging bag 1 is formed using a sheet material as shown in Fig. 1. The sheet material may be, for example, one made of a single sheet, may be formed by connecting a plurality of sheets (for example, ends of a plurality of sheets), may be made of a laminated sheet in which a plurality of sheets are stacked, or may be configured to include other members (for example, a piece of film, etc.).

[0017] The sheet material may be, for example, paper or resin. The resin sheet may be, for example, a film having tear directionality (for example, a uniaxially stretched film or a biaxially stretched film).

[0018] The sheet material is configured so that the opposing regions can be connected when folded back so that one side faces inward. Such a sheet material may have one side formed of a so-called easy-peel film, or may have a part coating applied to the connecting portion on one side of the sheet material. More specifically, the sheet material may include an OPP film, an easy-peel film, and a barrier layer (a layer of MXD, EVOH, VM, or the like) disposed between them.

[0019] The packaging bag 1 also includes a storage section 2 for storing an article, and a first extending section 3 and a second extending section 4 extending in different directions from the storage section 2. In this embodiment, the first extending section 3 and the second extending section 4 are formed at opposing positions in one direction (specifically, at opposing positions across the storage section 2) and are formed to extend from the storage section 2 in the opposite direction to the opposing direction (in other words, in the direction away from the storage section 2 in the one direction). The packaging bag 1 also includes a folded end 5 formed by folding the sheet material in two, and a connecting section 6 formed by connecting the opposing surfaces of the sheet material to each other at the end position other than the folded end 5 (specifically, by heat sealing, etc.). In this embodiment, the opposing surfaces of the sheet material are connected to each other over the entire area of ​​the first extending section 3 and the second extending section 4. In other words, the entire first extending section 3 and the second extending section 4 constitute a part of the connecting section 6.

[0020] The first extending portion 3 is formed in a band shape extending in the other direction intersecting the one direction. The first extending portion 3 includes a through portion 3a formed to penetrate itself. That is, the through portion 3a is formed to penetrate the connecting portion 6. In this embodiment, a plurality of through portions 3a (specifically, two) are formed at intervals in the other direction.

[0021] Further, the through portion 3a is composed of a cut line 3b formed by cutting the first extending portion 3 (connecting portion 6) linearly. In this embodiment, the cut line 3b is formed in a C-shape that opens toward the end side of the packaging bag 1 in the one direction (i.e., in the direction away from the storage portion 2). Specifically, the cut line 3b includes a first cut portion 3b1 extending in the other direction, and two second cut portions 3b2 extending from both ends of the first cut portion 3b1 toward the end side of the packaging bag 1 (i.e., in the direction away from the storage portion 2). In this embodiment, the first cut portion 3b1 is formed in a straight line, and each second cut portion 3b2 is formed curved so as to bulge from the first cut portion 3b1 in the other direction.

[0022] Furthermore, the distance between both ends 3b3, 3b3 of the cut line 3b (the distance in the other direction) may be narrower than the distance between both ends of the first cut portion 3b1 (the distance in the other direction), or may be substantially the same as the distance between both ends of the first cut portion 3b1 (the distance in the other direction). In other words, the both ends 3b3, 3b3 of the cut line 3b may be configured to overlap a portion closer to the center than the both ends of the first cut portion 3b1 in the one direction, or may be configured to overlap both ends of the first cut portion 3b1 in the one direction.

[0023] In this embodiment, the first extending portion 3 includes a hanging through portion 3c between the two through portions 3a, 3a, through which another member is inserted to hang the packaging bag 1 from the other member. The hanging through portion 3c is formed by cutting the first extending portion 3 into a C-shape that opens to the storage portion 2 side.

[0024] The second extending portion 4 is formed in a band shape extending in the other direction. The second extending portion 4 also includes an inserting portion 4a that can be inserted into the through portion 3a of the first extending portion 3. The inserting portion 4a is formed such that a part of the second extending portion 4 (in this embodiment, the connecting portion 6) extends further in the extending direction of the second extending portion 4. In this embodiment, a plurality of (two) inserting portions 4a are formed at intervals in the other direction. The inserting portion 4a is also formed at a position corresponding to the through portion 3a in the one direction.

[0025] The insertion portion 4a includes two convex portions 4b, 4b formed at opposing positions in the other direction so as to be convex in the other direction. The insertion portion 4a is also formed so as to taper from the two convex portions 4b, 4b toward the tip in the extension direction. The length between the two convex portions 4b, 4b of the insertion portion 4a (the length in the other direction) may be configured to be longer than the length of the through portion 3a in the other direction, or may be configured to be longer than the distance between both ends 3b3, 3b3 of the cut line in the other direction.

[0026] The packaging bag 1 configured as described above can be connected together. Specifically, the insertion portion 4a of the second extending portion 4 of one packaging bag 1 is inserted into the through portion 3a of the first extending portion 3 of another packaging bag 1 (inserted along the one direction in this embodiment). This allows the through portion 3a and the insertion portion 4a to engage with each other in the pulling direction (in this embodiment, the direction along the one direction) when the insertion portion 4a is pulled out of the through portion 3a. More specifically, the two convex portions 4b, 4b of the insertion portion 4a are formed to be convex in the intersecting direction (in this embodiment, the other direction) at opposing positions in the intersecting direction (in this embodiment, the one direction) that intersects with the pulling direction (in this embodiment, the one direction). Therefore, the two convex portions 4b, 4b of the insertion portion 4a are positioned outside the C-shaped cut line 3b when the insertion portion 4a is inserted into the through portion 3a. As a result, in the pulling-out direction (in this embodiment, the direction along the one direction), the inner edge of the penetrating portion 3a (in this embodiment, near both ends 3b3, 3b3 of the cut line 3b) engages with the two convex portions 4b, 4b of the insertion portion 4a. Then, as described above, the penetrating portion 3a engages with the insertion portion 4a, thereby forming a state in which one packaging bag 1 and another packaging bag 1 are connected to each other.

[0027] When releasing the connection between the first packaging bag 1 and the second packaging bag 1, the second packaging bag 1 is swung in the other direction (a direction intersecting the pull-out direction) around the insertion portion 4a. As a result, one of the two convex portions 4b of the insertion portion 4a moves to the inside of the C-shaped cut line 3b, and the engagement between the penetrating portion 3a and the insertion portion 4a is released, allowing the first packaging bag 1 to be separated from the second packaging bag 1.

[0028] As described above, according to the packaging bag of the present invention, when a plurality of packaging bags containing articles are displayed in a storefront or the like, the plurality of packaging bags can be easily visually identified.

[0029] That is, the through-hole 3a and the insertion portion 4a are configured to engage with each other in a direction in which the insertion portion 4a of the second extending portion 4 of one packaging bag 1 is pulled out from a state in which the insertion portion 4a is inserted into the through-hole 3a of the first extending portion 3 of another packaging bag 1. This allows a plurality of packaging bags 1 to be connected in the planar direction for display, making the plurality of packaging bags 1 easy to view.

[0030] The insertion portion 4a also includes two convex portions 4b formed at opposing positions in a cross direction intersecting the pulling-out direction so as to be convex in the cross direction. The length between the tips of the two convex portions 4b in the cross direction is configured to be longer than the length of the through portion 3a in the cross direction. This makes it easier for the two convex portions 4b to be hooked onto the inner edge of the through portion 3a in the direction in which the insertion portion 4a is pulled out from the state in which the insertion portion 4a is inserted into the through portion 3a. This makes it possible to maintain a good connection state between the packaging bags 1.

[0031] The through portion 3a is composed of a cut line 3b formed by cutting the first extending portion 3 linearly. The cut line 3b is formed in a C-shape that opens toward the pulling-out direction. The length between the tips of the two convex portions 4b in the crossing direction is configured to be longer than the distance between both ends of the cut line 3b in the crossing direction. This makes it easier for the two convex portions 4b to be hooked onto the inner edge of the through portion 3a near both ends of the cut line 3b in the direction in which the insertion portion 4a is pulled out from the state in which the insertion portion 4a is inserted into the through portion 3a. This makes it possible to better maintain the connection state between the packaging bags 1.

[0032] The packaging bag according to the present invention is not limited to the above-mentioned embodiment, and various modifications are possible without departing from the scope of the present invention. In addition, the configurations, methods, etc. of the above-mentioned embodiments may be arbitrarily adopted and combined (the configurations, methods, etc. of one embodiment may be applied to the configurations, methods, etc. of other embodiments), and further, the configurations, methods, etc. of the following various modified examples may be arbitrarily selected and adopted in the configurations, methods, etc. of the above-mentioned embodiments.

[0033] For example, in the above embodiment, the entire first extension portion 3 and the second extension portion 4 constitute a part of the connecting portion 6, but this is not limited thereto. For example, at least one of the first extension portion 3 and the second extension portion 4 may have a portion where the facing surfaces of the sheet materials are not connected to each other. Specifically, as shown in FIG. 2, the first extension portion 3 and the second extension portion 4 may be configured to have a non-connecting portion 7 where the facing surfaces of the sheet materials are not connected to each other. Then, a through portion 3a may be formed in the non-connecting portion 7 of the first extension portion 3, and an insertion portion 4a may be formed in the non-connecting portion 7 of the second extension portion 4. Note that in the non-connecting portion 7, parts of the sheet materials may or may not overlap each other.

[0034] In addition, in the above embodiment, the first extension portion 3 and the second extension portion 4 are formed in opposing positions in the one direction, but this is not limited to this, and for example, as shown in Figure 3, the first extension portion 3 may be configured to extend in the one direction and the second extension portion 4 may be configured to extend in the other direction.

[0035] In addition, in the above embodiment, the packaging bag 1 is configured to have one folded end 5, but is not limited to this, and may be configured to have two folded ends 5, 5 formed at opposing positions in the other direction, for example, as shown in Fig. 4. In such a case, the packaging bag 1 may be configured to have a back-attached portion 8 (a portion where the ends of the sheet material are connected in a region extending in the one direction) extending in the one direction at a position between the two folded ends 5, 5.

[0036] In addition, in the above embodiment, the cut line 3b is formed in a C-shape that opens toward the end side of the packaging bag 1 (the side away from the storage section 2), but this is not limited to this, and for example, it may be formed in a C-shape that opens toward the storage section 2 side, or it may be formed in a straight line extending in the other direction.

[0037] In the above embodiment, the packaging bag 1 is configured to have at least one folded end 5, but is not limited thereto, and may be configured to have no folded end 5, for example, as shown in Fig. 5. In such a packaging bag 1, two sheets of overlapping sheet material are configured such that their outer peripheral ends are connected (sealed) to each other along the entire circumference. In other words, in such a packaging bag 1, a connecting portion 6 is formed along the entire circumference of the outer peripheral ends.

[0038] Furthermore, in the packaging bag 1 according to each of the above embodiments, when an opening for removing the stored article is formed between the regions extending in the other direction at opposing positions on the inner surface of the storage section 2 (for example, when the opening is formed by cutting the storage section 2 in the other direction), the packaging bag 1 may be configured to include a closing member (not shown) for closing the opening. For example, a closing member (so-called zipper member) that closes the opening by fitting into the recesses can be provided in the opposing regions on the inner surface of the storage section 2 that form the opening.
