The character designs arranged on the front side and the back side of the packaging bag are images, barcodes, and characters necessary for management, such as an image, a bar code, and an ingredient display, which are easy for the purchaser to see compared to other competing products. Therefore, the appearance may not match the purchaser's living room or belongings.

The packaging bag may also contain supplements, regular medicines, and the like. Supplements, household medicines, etc. may be taken when going out. Even if you do not want others to know the names of the supplements or medicines you are taking, there is a risk that others will know from the above-described patterns, characters, etc. on the packaging bag.

In such a case, the purchaser may take out the content contained in the packaging bag and transfer it to a separately prepared container for use, but the transfer is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a packaging bag whose outer packaging can be changed according to the conditions of use and the atmosphere of the arrangement position.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of using a packaging bag whose exterior can be easily changed.

In order to achieve the above object, the packaging bag of the present invention comprises a front sheet and a back sheet which are superimposed and heat-bonded at the peripheries thereof, wherein the front sheet and the back sheet are formed with a base layer and an inner side of the base layer. and a heat-adhesive resin layer disposed on. At least one of the front sheet and the back sheet has a release layer that separably holds a first laminate containing the base material layer and a second laminate containing the thermoadhesive resin layer. The first laminate includes a first printed layer on which a first pattern is formed, and the second laminate includes a second printed layer on which a second pattern is formed. When the first laminate is separated from the second laminate, the first printed layer remains on the first laminate and the second printed layer remains on the second laminate.

According to this configuration, in the packaging bag, the first design can be visually recognized from the outside when the first laminate is present, and the second design can be visually recognized from the outside when the first laminate is removed. That is, depending on whether or not the first laminate is removed, the design of the outer layer of the packaging bag can be the first design or the second design. The user can select the exterior of the packaging bag from the first design and the second design by removing or leaving the first laminate as necessary. For example, the packaging bag can have an exterior with a conspicuous first pattern containing information for distinguishing the product from other products when it is sold. In addition, when used after purchase, the exterior can be a calm second design that blends in with the surrounding atmosphere.

As a result, the exterior of the packaging bag can have different designs depending on the location where it is used (arranged). The packaging bag can change the exterior according to the atmosphere of the place, and can improve convenience for the user.

The above configuration may further include an intermediate layer laminated between the release layer and the thermoadhesive resin layer, and the intermediate layer may be formed with a cutting line dividing the intermediate layer into upper and lower parts. . By configuring in this way, shear stress is generated along the cutting line in the layer bonded to the intermediate layer by twisting the intermediate layer so as to separate the upper and lower portions from the cutting line back and forth. The layer adhered to the intermediate layer is cut along the cutting line. Moreover, the release layer that is not adhered to the intermediate layer is separated from the intermediate layer by this shear stress. Thereby, the release layer can be easily separated from the intermediate layer.

In the above configuration, when the first laminate is removed from the second laminate, the release layer may remain on either the first laminate or the second laminate.

In the above configuration, when the first laminate is removed from the second laminate, part of the release layer may remain on the first laminate and the rest may remain on the second laminate. .

In the above configuration, the first design may hide at least part of the second design.

In the above configuration, at least a part of the first design may include a visible portion that allows the inside to be visually recognized, and the first design and the second design may be overlapped to form a third design. By configuring in this way, it is possible to select information to be displayed externally depending on the time and place of use. Thereby, it is possible to improve convenience for the user.

The said structure WHEREIN: A said 1st pattern may be equipped with a transparent window part as said visible part.

In the above configuration, it may be recloseable after opening.

In order to achieve the above object, the method of using the packaging bag of the present invention may be such that the first laminate is removed from the second laminate and the second design is visible.

In the above configuration, part or all of the first laminate may be removed from the second laminate when unsealed. By doing so, it is possible to save the trouble of removing the first laminate from the second laminate. In addition, it can be determined whether the package has been opened or not by the pattern that can be visually recognized from the outside.

According to the packaging bag of the present invention, the outer packaging can be changed according to the conditions of use and the atmosphere of the arrangement position.

According to the method of using the packaging bag of the present invention, it is easy to change the outer packaging.

That is, in the packaging bag 1 shown in FIG. 1, the front surface portion 5 is on the front side of the paper surface, and the back surface portion 6 located behind the front surface portion 5 is on the back side of the paper surface. Further, in the packaging bag 1 shown in FIG. 1, the heat-bonded portion 31 is indicated by hatching.

<About packaging bag 1>
As shown in FIG. 1, a packaging bag 1 is formed by a so-called standing pouch, and has a bag body 2 and a zipper member 3. As shown in FIG. The chuck member 3 is made of resin and adhered to the upper inner surface of the bag body 2 .

The bag body 2 has a front portion 5 , a back portion 6 and a bottom portion 8 . A thermoadhesive resin layer 16 (see FIG. 2) of the front sheet 100 constituting the front part 5 and a thermoadhesive resin layer 24 disposed on the inner surface of the back sheet 200 constituting the back part 6 are formed on the periphery of the bag body 2 . (see FIG. 3) is disposed.

The front part 5 and the back part 6 face each other and are bonded to each other by the heat bonding part 31 at the upper part of the side end and the upper end part. The bottom part 8 is sandwiched between the lower part of the front part 5 and the lower part of the back part 6 by folding the back sheet 200 in two, and is attached to the lower and lower side ends of the front part 5 and the back part 6 by the thermal bonding part 31 . Thermally bonded. The upper end of the bag main body 2 is open, and is thermally bonded by the thermal bonding portion 31 after the contents S are accommodated.

Below the chuck member 3 of the bag main body 2, a containing portion 4 for containing the contents S is formed. By opening and closing the chuck member 3, the upper surface of the accommodating portion 4 is opened and closed. In addition, although the content S can include, for example, foods, seasonings, supplements, medicines, insecticides, etc., the content S is not limited to these.

In the packaging bag 1, a zipper member 3 is arranged below the opening at the upper end. The chuck member 3 has a conventionally well-known structure, and is opened by pulling the upper end portions of the front portion 5 and the rear portion 6 back and forth. In addition, the chuck member 3 is closed by stacking the front portion 5 side and the rear portion 6 side of the chuck member 3 back and forth and pressing from the outside. Therefore, even after the packaging bag 1 is opened once, the contents S can be accommodated inside the accommodating portion 4 . That is, the packaging bag 1 is provided with the chuck member 3, so that it can be closed after being opened, that is, recloseable.

Curved notch portions 32 are formed on the heat-bonded portions 31 on both side edges of the bag body 2 above the chuck member 3 .

An opening is formed in the packaging bag 1 by extending the crack. In addition, the part above the notch part 32 is torn so as to be pulled forward. The tearing method may be indicated on the front part 5 or the back part 6 of the packaging bag 1 .

<About the front sheet 100 and the back sheet 200>
Next, details of the front sheet 100 and the back sheet 200 will be described. As shown in FIG. 2, the front sheet 100 constituting the front part 5 comprises a base material layer 11, a first printed layer 12, a release layer 13, an intermediate layer 14, and a second printed layer in this order from the outside to the inside of the bag body 2. Layer 15 and thermoadhesive resin layer 16 are laminated. A first printed layer 12 is formed inside the base material layer 11 and adhered to the release layer 13 via an adhesive layer 17 . Furthermore, a second printed layer 15 is formed inside the intermediate layer 14 and adhered to the thermoadhesive resin layer 16 via an adhesive layer 18 .

The substrate layer 11 is formed of, for example, a biaxially oriented polyethylene terephthalate (PET) film having a thickness of about 9-25 μm. As the substrate layer 11, for example, a thermoplastic resin such as a uniaxially or biaxially stretched polypropylene (OPP) film or an oriented nylon (ONY) film can be used.

A first printed layer 12 for printing a pattern or the like is formed at a predetermined position on the inner surface of the base material layer 11 . The first printed layer 12 is formed to have a thickness of about 1 to 5 μm with ink placed at predetermined positions on the inner surface of the base material layer 11 . The base material layer 11 is transparent, and the first printed layer 12 is visible from the outside. Therefore, a pattern that can be recognized from the outside of the base material layer 11 is formed on the first printed layer 12 . The pattern or the like printed on the first printed layer 12 may be, but is not limited to, an indication of the components of the contained object S, the name of the product, an image, or the like. The first printed layer 12 may be provided on the upper surface (outside) of the substrate layer 11, but by arranging the first printed layer 12 between the substrate layer 11 and the release layer 13, the printing can be suppressed from rubbing or disappearing. The release layer 13 is formed by printing, for example.

The intermediate layer 14 is made of, for example, polyethylene terephthalate (PET), oriented nylon (ONY), or the like. Inside the intermediate layer 14, a second printed layer 15 having a thickness of about 1 to 5 μm is formed with ink. The second printed layer 15 has a pattern that can be recognized from the outside of the packaging bag 1 . The second printed layer 15 may be formed outside the intermediate layer 14 . At this time, the second printed layer 15 is arranged on the outer surface of the packaging bag 1 . In this case, the second printed layer 15 may come off due to rubbing or the like. On the other hand, the user can deform (scrape off) a second pattern Pt2 to be formed on the second printed layer 15 according to his/her preference. The user's convenience can be enhanced because the changeable range is widened.

A metal foil layer (not shown) made of metal foil may be provided below the second printed layer 15 . Examples of the metal foil layer include, but are not limited to, those formed of aluminum foil. A metal foil layer is less permeable to oxygen, water vapor, etc. than many resin layers. Oxidation of the stored material can thereby be suppressed. In addition, the metal foil layer has a lower UV transmittance than many resin layers. As a result, it is possible to suppress the deterioration of the contents due to ultraviolet rays. In other words, by providing the metal foil layer, it becomes possible to store the contained object S for a long period of time.

The thermoadhesive resin layer 16 is made of, for example, a non-stretched polypropylene (CPP) film having a thickness of about 25-150 μm. Also, the heat-adhesive resin layer 16 may be formed of linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), or a blend resin thereof (easy peel).

The adhesive layer 17 and the adhesive layer 18 are made of, for example, a urethane-based adhesive. The substrate layer 11 and the release layer 13 are adhered via the adhesive layer 17 . Also, the intermediate layer 14 and the thermoadhesive resin layer 16 are adhered via the adhesive layer 18 . Bonding by the adhesive layer 17 and the adhesive layer 18 is performed by a dry lamination method. However, it is not limited to this. For example, the adhesive layer 17 and the adhesive layer 18 are formed of a polyethylene film or the like, and extruded using an extrusion coater (not shown) or the like to form the substrate layer 11, the release layer 13, the intermediate layer 14, and the thermoadhesive resin layer. 16 may be glued.

The adhesive layer 17 may be formed by a dry lamination method on the substrate layer 11 after forming the first printed layer 12 . Alternatively, the first printed layer 12 may be formed after the adhesive layer 17 is formed on the base material layer 11 . Similarly, the adhesive layer 18 may be formed by dry lamination on the intermediate layer 14 after forming the second printed layer 15 . Alternatively, the second printed layer 15 may be formed after forming the adhesive layer 18 on the intermediate layer 14 .

In the front sheet 100 , a laminate including the base material layer 11 , the first printed layer 12 and the release layer is referred to as a first laminate 101 . A laminate of the intermediate layer 14 , the second printed layer 15 and the thermoadhesive resin layer 16 is referred to as a second laminate 102 .

In front sheet 100 , release layer 13 is adhered to base layer 11 and separated from intermediate layer 14 . However, it is not limited to this, and the release layer 13 is provided with a layer adhered to the base material layer 11 and a layer adhered to the intermediate layer 14, and these layers are fixed by the method described above. may Alternatively, the release layer 13 may be arranged between the intermediate layer 14 and the thermoadhesive resin layer 16 so that the intermediate layer 14 can be separated from the base material layer 11 .

A cut portion 7 of the front portion 5 is a half-cut line. Here, the half-cut line refers to a recess formed in a part of the laminated front sheet 100 or a cutting line that penetrates through the front sheet 100, and has a shape that does not penetrate all the layers of the front sheet 100. Point. In this embodiment, the cut portion 7 of the front portion 5 is a cut line 70 formed in the intermediate layer 14 .

As shown in FIG. 3, the back sheet 200 constituting the back portion 6 is formed by laminating a base material layer 21, a printed layer 22, an intermediate layer 23, and a thermoadhesive resin layer 24 in order from the outside to the inside of the bag body 2. formed by

The base layer 21 is made of, for example, a biaxially oriented polyethylene terephthalate (PET) film having a thickness of about 9-25 μm. As the base material layer 21, for example, a thermoplastic resin such as a uniaxially or biaxially stretched polypropylene (OPP) film or an oriented nylon (ONY) film can be used.

The printed layer 22 is formed to a thickness of about 1 to 5 μm with ink placed at predetermined positions on the inner surface of the base material layer 21 . The printed layer 22 is visually recognized from the outside. Therefore, a pattern that can be recognized from the outside is formed on the printed layer 22 . The pattern printed on the printed layer 22 may include the display of the components of the contents S, the details of the manufacturer, the date of manufacture, the bar code of the product, and the like. Note that the printed layer 22 may be provided on the outer surface of the base material layer 21 .

The intermediate layer 23 is made of, for example, polyethylene terephthalate (PET), oriented nylon (ONY), or the like. A metal foil layer (not shown) made of metal foil may be used instead of the intermediate layer 23 . Examples of the metal foil include, but are not limited to, those made of aluminum. A metal foil layer is less permeable to oxygen, water vapor, etc. than many resin layers. Oxidation of the stored material can thereby be suppressed. In addition, the metal foil layer has a lower UV transmittance than many resin layers. As a result, it is possible to suppress the deterioration of the contents due to ultraviolet rays. In other words, by providing the metal foil layer, it becomes possible to store the contained object S for a long period of time.

The thermoadhesive resin layer 24 is made of, for example, a non-stretched polypropylene (CPP) film having a thickness of about 25-150 μm. Alternatively, the heat-adhesive resin layer 24 may be formed of a linear low-density polyethylene (LLDPE) film or a low-density polyethylene (LDPE) film. Moreover, a polyethylene film may be used.

The adhesive layers 25 and 26 are made of, for example, a urethane-based adhesive. The base layer 21 and the intermediate layer 23 are adhered via the adhesive layer 25 by a dry lamination method. Similarly, the intermediate layer 23 and the thermoadhesive resin layer 24 are adhered via the adhesive layer 26 by dry lamination. It should be noted that the base layer 21, the intermediate layer 23, and the thermoadhesive resin layer 24 are formed on the adhesive layer 25 and the adhesive layer 26 by, for example, an extrusion method using an extrusion coater (not shown) or the like. It can be glued.

The adhesive layer 25 may be formed by a dry lamination method on the base material layer 21 after forming the printed layer 22 . Alternatively, the printed layer 22 may be formed after the adhesive layer 25 is formed on the base material layer 21 .

A cut portion 7 of the back portion 6 is also a half-cut line. In this embodiment, the cut portion 7 of the back portion 6 is a cut line 70 formed in the intermediate layer 23 .

The packaging bag 1 of this embodiment can be reclosed by the chuck member 3 . However, it is not limited to this. At least one of the front sheet 100 and the back sheet 200 is provided with a dead hold property by using aluminum or the like, for example. Then, the deadhold property may be used to make the opening recloseable. Note that the deadhold property is a property that allows the seat to maintain a deformed state such as a closed state or an open state due to the rigidity of the sheet. In addition to these, it is possible to adopt a wide range of configurations that can be reclosed after opening.

<How to use the packaging bag 1>
Next, how to use the packaging bag according to the present invention will be described with reference to the drawings. FIG. 4 is a front view of the packaging bag 1 according to the invention. FIG. 5 is a front view showing a state in the middle of removing the first laminate 101 of the packaging bag 1 according to the present invention. FIG. 6 is a front view showing a state in which the first laminate 101 is removed from the packaging bag 1 according to the present invention. 6 shows a state in which the upper portion is removed from the notch portion 32. As shown in FIG. That is, the packaging bag 1 shown in FIG. 6 is opened.

As described above, the front sheet 100 of the front portion 5 of the packaging bag 1 can be separated into the first laminate 101 and the second laminate 102 by the release layer 13 . A first printed layer 12 is formed on the lower side of the base material layer 11 of the first laminate 101 . The base material layer 11 is transparent. Therefore, the user using the packaging bag 1 can visually recognize the first pattern Pt1 formed on the first printed layer 12 from above the base material layer 11 . Also, the first pattern Pt1 formed on the first printed layer 12 includes an image formed over the entire portion that can be seen from the front side. Therefore, when viewed from the front side, the rear side of the first pattern Pt1 formed on the first printed layer 12 cannot be seen. That is, in the packaging bag 1, when the first laminate 101 is attached, the second pattern Pt2 formed on the second printed layer 15 is hidden behind the first pattern Pt1 and cannot be seen.

As described above, the second laminate 102 is thermally bonded to the rear surface portion 6 . Therefore, the first laminate 101 can be removed from the second laminate 102 , that is, the packaging bag 1 by peeling the peel layer 13 .

In the packaging bag 1 of the present embodiment, the intermediate layer 14 of the front sheet 100 and the intermediate layer 23 of the back sheet 200 are formed with cut portions 7 consisting of cutting lines 70 . The user grips the top and bottom of the notch part 32 with fingers, moves the upper side to the front side and the lower side to the back side, and twists it to open the packaging bag 1.例文帳に追加Next, opening of the packaging bag 1 will be described.

First, the cutting of the backsheet 200 will be described. A cutting line 70 is formed in the intermediate layer 23 of the back sheet 200 . The base layer 21 and the thermoadhesive resin layer 24 are adhered to the intermediate layer 23 via the adhesive layer 25 and the adhesive layer 26, respectively (see FIG. 3). Therefore, by twisting the packaging bag 1 as described above, shear stress acts on the base material layer 21 and the thermoadhesive resin layer 24 along the cutting line 70 . Thereby, the base material layer 21 and the thermoadhesive resin layer 24 are cut along the cutting line 70 .

Next, cutting of the front sheet 100 will be described. In front sheet 100 , cutting line 70 is formed in intermediate layer 14 included in second laminate 102 of release layer 13 . The intermediate layer 14 is adhered to the thermoadhesive resin layer 16 via the adhesive layer 18 (see FIG. 2). Therefore, when the intermediate layer 14 is twisted as described above, the portions above and below the cutting line 70 of the intermediate layer 14 are displaced back and forth along the cutting line 70 relative to each other. Then, the displacement is transmitted to the thermoadhesive resin layer 16 , and shear stress acts along the cutting line 70 . As a result, the thermal adhesive resin layer 16 is cracked along the cutting line 70 .

On the other hand, the peeling layer 13 of the first laminate 101 is fixed to the intermediate layer 14 so as to be peelable. Therefore, when the packaging bag 1 is twisted as described above, displacement of the intermediate layer 14 is less likely to be transmitted to the release layer 13 . Therefore, when the packaging bag 1 is twisted as described above, shear stress is less likely to act on the release layer 13 and the base material layer 11 adhered to the release layer 13 via the adhesive layer 17 . Also, while the intermediate layer 14 is displaced, the release layer 13 is less likely to be displaced. Due to this displacement difference between the intermediate layer 14 and the release layer 13 , a stress acts between the release layer 13 and the intermediate layer 14 in the direction of mutual separation, and the separation of the release layer 13 is started.

As described above, the second laminate 102 of the back sheet 200 and the front sheet 100 is cut along the cutting line 70 when the packaging bag 1 is twisted as described above. Meanwhile, the release layer 13 is peeled off from the intermediate layer 14, and the first laminate 101 is peeled off from the second laminate 102 (see FIG. 5). Since the tip of the notch portion 32 is loose (curved), stress in the peeling direction tends to concentrate between the peeling layer 13 and the intermediate layer 14 . This also facilitates the separation of the release layer 13 and the intermediate layer 14, thereby removing the first laminate 101 from the second laminate.

As described above, in the packaging bag 1 of the present embodiment, the first laminate 101 of the front sheet 100 can be separated from the second laminate 102 by pinching and tearing the top and bottom of the notch portion 32. . Therefore, peeling of the first laminate 101 is easy. Further, whether or not the packaging bag 1 has been opened can be confirmed by checking whether or not the first laminate 101 has been removed. Therefore, it is possible to confirm whether or not the packaging bag 1 is unopened by simply looking at the packaging bag 1 from a remote position.

By removing the first laminate 101 from the packaging bag 1, the base layer 11 and the first printed layer 12 are removed. As shown in FIG. 6, by removing the first laminate 101, the user can visually recognize the second printed layer 15 from the front side. That is, the user can visually recognize the second pattern Pt2 formed on the second printed layer 15 from the front portion 5 side.

Thus, when the first laminate 101 of the front part 5 is present, the user can visually recognize the first pattern Pt1 formed on the first printed layer 12 from the front side. Further, by peeling and removing the first laminate 101, the user can visually recognize the second pattern Pt2 formed on the second printed layer 15 from the front side.

<Regarding the first pattern Pt1 and the second pattern Pt2>
Here, the first pattern Pt1 and the second pattern Pt2 will be explained. For example, the contents S contained in the packaging bag 1 are supplements claiming weight loss effects, so-called diet supplements. The diet supplements, which are the contents S, are displayed side by side on the sales shelf of the store in a state of being housed in the packaging bag 1.例文帳に追加At this time, the packaging bag 1 is displayed on the sales shelf so that the front part 5 side faces up. That is, the packaging bag 1 displayed on the sales shelf is visually recognized by the purchaser (user) from the front side. The first laminate 101 of the front sheet 100 is not removed from the packaging bag 1 before opening. Therefore, when the packaging bag 1 is displayed on the sales shelf, the purchaser visually recognizes the first pattern Pt1 formed on the first printed layer 12 of the packaging bag 1 .

Usually, on sales shelves, products of different brands may be displayed side by side for each type of product. In addition, depending on the store, there are cases where the products are collectively displayed on the sales shelf for each brand. When the products are collectively displayed for each type, the packaging bag 1 with conspicuous color, design, product name, brand name, and product features is likely to be purchased. In addition, even when the product is displayed for each brand, the front part 5 of the packaging bag 1 includes the name of the product and the name of the product so that the purchaser can quickly recognize the product to be purchased. Features are formed to stand out. In addition, colors and designs are sometimes selected to match the brand image.

That is, as shown in FIG. 4, the first pattern Pt1 formed on the first printed layer 12 includes a base Wp, a product name Pn, a brand name Bn, a first characteristic display Ch1, and a second characteristic display Ch2. and In the drawing, each item of the pattern is surrounded by a two-dot chain line, but the two-dot chain line is not displayed in the actual pattern.

The background Wp is the background of the first pattern Pt1. The color of the undercoat Wp that is easy to stand out is more noticeable to the purchaser. Therefore, in the first pattern Pt1, the background Wp can be, for example, yellow. Also, depending on the brand, an image color may be set, and in that case, the color of the brand image may be selected. Furthermore, in the case of the product itself or a series of products, image colors may be set depending on the series, and even in such cases, the colors of those images may be selected.

The product name Pn is the name of the content. For example, the product name Pn is placed above the first pattern Pt1 in order to make it easier to see even when the packaging bags 1 are stacked. Also, there are purchasers who decide to purchase a product by looking at the product name Pn. Therefore, the product name Pn may have an eye-catching font, color, and size so that the purchaser can easily see it. In FIG. 4, the wording "XYZ supplement" is the product name Pn.

The brand name Bn is the brand name or brand logo of the manufacturer who manufactured the contained item S, which is the product, or the distributor who sells the product. The brand name Bn is arranged close to the product name Pn. The brand name Bn may include the product series name in addition to the brand name. Some purchasers decide to purchase based on the brand name Bn. Therefore, the brand name Bn, like the product name Pn, may have a conspicuous font, color, and size. In FIG. 4, the wording "XYZ Farmer" is the brand name Bn.

The first characteristic display Ch1 describes, in characters, the effect and efficacy of ingestion among the characteristics of the contained item S, which is a product. In FIG. 4, a phrase such as "suppresses absorption of sugar and fat and helps burn fat in the body" is the first characteristic display Ch1. In addition to these, ingredients contained in the container S that are commonly seen on a daily basis, such as "DHA", "EPA", "collagen", "capsaicin", etc., may be described. The second characteristic display Ch2 displays an image that reminds the purchaser of dieting, for example, an image of cooking.

As shown in FIG. 6, the second pattern Pt2 is an image of a wide-mouthed bottle Bn1 having an opening at the top and a lid Cp1 that closes the opening of the wide-mouthed bottle Bn1. By removing the first laminate 101 from the packaging bag 1, the second pattern Pt2 formed on the second printed layer 15 can be visually recognized from the front side. The intermediate layer 14 and the thermoadhesive resin layer 16 are transparent. As a result, the user can visually recognize from the front side that the contents S are stored inside the transparent wide-mouthed bottle Bn1.

The second pattern Pt2 is not limited to the jar Bn1 and the lid Cp1. For example, it may be a pattern of another container. In addition, it is not limited to the container, and a wide range of patterns that can be arranged in a well-balanced manner can be adopted with respect to the user's belongings and the design of the living room. For example, as the second pattern Pt2, a pattern with a simple configuration can be mentioned. A design with a simple configuration is easy to adapt to the surrounding environment and is easy to use as the packaging bag 1 for containing the contents S. Conversely, the first pattern Pt1 may be flashier than the first pattern Pt1, in other words, a more conspicuous pattern. Even in this case, by not displaying the product name Pn, the brand name Bn, the first characteristic display Ch1, the second characteristic display Ch2, and the like, it is difficult for others to know the contents S.

The first pattern Pt1 is a pattern that gives priority to being conspicuous in the shop. Therefore, by looking at the first pattern Pt1, even a person other than the user can understand what kind of product (here, diet supplement) the contained item S is.

Such diet supplements may be taken on the go, but there are also cases where the user does not want others to know that they are taking them. When the packaging bag 1 in which the first pattern Pt1 is formed on the front part 5 is taken out of the bag or the like on the go, it becomes easy for other people to know the type of supplement (diet supplement) taken. Therefore, the user uses the packaging bag 1 in which the first laminate 101 is peeled off so that the second pattern Pt2 can be visually recognized. As shown in FIG. 6, the second pattern Pt2 does not include notations that specify the contained object S, such as the product name Pn, the brand name Bn, the first characteristic display Ch1 and the second characteristic display Ch2. . As a result, for example, even if the packaging bag 1 is seen by others, it is difficult for them to know the contents S.

In addition, some users organize the appearance of belongings to be put in a bag for going out in the same system. In such a case, the packaging bag 1 in which the first pattern Pt1 with the product name Pn or the like is conspicuous is formed on the front portion 5 may be difficult to match visually with other belongings. As shown in FIG. 6, by making the second pattern Pt2 a simple pattern, it is visually easy to fit in with the user's living room and belongings. That is, even if there is resistance to the packaging bag 1 in which the conspicuous first pattern Pt1 is displayed on the front portion 5, the packaging bag 1 in which the simple second pattern Pt2 is displayed on the front portion 5 can be used. , can reduce the resistance of the user. Therefore, the user does not have to replace the container of the stored article S in order to visually balance it with the living room and other belongings, which saves time and effort.

By using such a packaging bag 1, it is possible to sell the product with a conspicuous pattern displayed on the front. Then, when the user uses it, it is possible to use it with the design as it is, and it is also possible to use it with a simple design that is visually familiar with the surroundings. It is not necessary to transfer the stored object S to another container in order to make it visually familiar with the surroundings, and it is possible to enhance the convenience for the user.

In addition, in this embodiment, a supplement is mentioned as the content S, but it is not limited to this. In addition to these, food products such as sprinkles, dressings, seasonings, dried foods such as dried noodles, and the like can be mentioned. Even in the case of such food, the appearance of the packaging bag 1 after opening is the second pattern Pt2, so that the packaging bag 1 can be arranged in a visually well-balanced manner with the interior of the living room, for example, the kitchen, and the furnishings. be able to. Further, as the stored items S, tools such as screws and nuts, and items other than foodstuffs such as toys can be mentioned. That is, as the storage object S, an object having a size that can be stored in the storage unit 4 can be adopted.

In addition, in the packaging bag 1 of the present embodiment, the intermediate layer 14 and the thermoadhesive resin layer 16 are made of transparent resin, so that the contents S can be visually recognized from the front side. However, it is not limited to this. For example, the intermediate layer 14 is formed of an opaque resin, the entire surface is painted with the second pattern Pt2 formed on the second printed layer 15, or an opaque layer such as a metal foil layer is placed between the intermediate layer 14 and the thermoadhesive resin layer 16. , etc., so that the stored object S cannot be visually recognized.

<Modification>
The release layer 13 may be made of polyethylene or the like. At this time, it is formed outside the intermediate layer 14 by an extrusion method using an extrusion coater (not shown) or the like. The intermediate layer 14 made of polyethylene terephthalate, stretched nylon, or the like and the release layer 13 made of polyethylene or the like are not adhered to each other because there is no anchor coat layer between them, but are only fixed. That is, the release layer 13 can be separated from the intermediate layer 14 by applying a force to the release layer 13 in a direction away from the intermediate layer 14 . Even with this configuration, the first laminate 101 and the second laminate 102 can be easily separated as in the above configuration.

<Second embodiment>
Another example of the packaging bag according to the present invention will be described with reference to the drawings. FIG. 7 is a front view of another example of the packaging bag 1b according to the present invention. FIG. 8 is a front view showing a state in which the first laminate 101b of another example of the packaging bag 1b according to the present invention is peeled off. In the packaging bag 1b according to the present embodiment, the first laminate 101b is different from the first laminate 101, and the first pattern Pt1b, the second pattern Pt2b and the third pattern Pt3b are the same as the first pattern Pt1 and the second pattern Pt2. It is the same as the packaging bag 1 except that it is different from . Therefore, portions of the packaging bag 1b that are substantially the same as those of the packaging bag 1 are denoted by the same reference numerals, and detailed description of the same portions is omitted.

Let the content accommodated in the packaging bag 1b of this embodiment be an insecticide, for example. A third pattern Pt3b can be visually recognized on the front side of the packaging bag 1b containing an insecticide. The third pattern Pt3b is a pattern combining the first patterns Pt1b and Pt2b.

Details of the third pattern Pt3b will be described. The third pattern Pt3b is configured by overlapping the first pattern Pt1b on the front surface of the second pattern Pt2b. The first pattern Pt1b includes a base Wp, a brand name Bn, a second characteristic display Ch2, a first window Wd1, and a second window Wd2. The base Wp, the brand name Bn and the second characterizing Ch2 are the same as the base Wp, the brand name Bn and the second characterizing Ch2 of the first pattern Pt1.

The first window portion Wd1 and the second window portion Wd2 of the first pattern Pt1b have a configuration in which a portion of the base Wp is made transparent. In the first pattern Pt1b, the first window portion Wd1 and the second window portion Wd2 are windows through which the rear side can be visually recognized from the front side. That is, the first window portion Wd1 and the second window portion Wd2 are examples of visible portions.

As shown in FIG. 8, the second pattern Pt2b is an image of a jar Bn1 whose lid member is a jar Bn1 and a lid Cp1 that closes the opening of the jar Bn1. The second pattern Pt2b includes a product name Pnb and a first characteristic display Ch1b. The product name Pnb and the first characteristic display Ch1b are equivalent to the product name Pn and the first characteristic display Ch1 of the first pattern Pt1 of the packaging bag 1 of the first embodiment, but are provided in the second pattern Pt2b. different in that Before the first laminate 101b is removed, the product name Pnb overlaps the first window Wd1 and the first characteristic display Ch1b overlaps the second window Wd2.

Before the first stacked body 101b is removed, the first pattern Pt1b overlaps in front of the second pattern Pt2b. As a result, in the front part 5 of the packaging bag 1b, the product name Pnb of the second pattern Pt2b can be visually recognized through the first window Wd1 of the first pattern Pt1b, and the second window Wd2 of the first pattern Pt1b can be viewed through the second window Wd2 of the first pattern Pt1b. The first characteristic display Ch1b of the pattern Pt2b becomes visible. That is, the third pattern Pt3b includes a base Wp, a brand name Bn, a product name Pnb, a first characteristic display Ch1b, and a second characteristic display Ch2. In other words, on the front surface portion 5 of the packaging bag 1b, the third pattern Pt3b is formed by overlapping the first pattern Pt1b and the second pattern Pt2b.

By forming in this way, even after the first laminated body 101b of the front part 5 is peeled off, the display of the product name Pnb and the first characteristic display Ch1b remains on the second pattern Pt2b.

There is a demand from users that they do not want to place such pests in places where they can see them, even if they are photographs. Further, the base Wp and the brand name Bn are intended to be easily noticed by the purchaser (user) at the time of purchase, and are often unnecessary when the product is left in the living room after purchase.

On the other hand, when the packaging bag 1b is left in the living room, the user has to check the contents if the contents of the packaging bag 1b are unknown. In the case of storing items that may adversely affect the user's body, such as insecticides, it may be difficult to confirm the stored items. For this reason, when storing items that may adversely affect the user's body, such as insecticides, it is preferable that the contents can be clearly seen even when viewed from the front.

Therefore, in the packaging bag 1b, the product name Pnb indicating what the contents are and the first characteristic display Ch1b including the cautionary note are arranged in the second pattern Pt2b. Further, even before the first laminate 101b is peeled off, a third pattern Pt3b is formed on the front surface portion 5 through the first window Wd1 so that the product name Pnb and the first characteristic indication Ch1b can be visually recognized through the second window Wd2. do.
