[0001] The present invention relates to a package. [Background technology]
[0002] Conventionally, there are known wet tissue packages that contain a plurality of wet tissues and pocket tissue packages that contain a plurality of tissues. Such wet tissue packages and pocket tissue packages are often carried and used when going out, etc.
[0003] However, when a user is out and about and has used wet tissues or tissue paper contained in a package, if there is no trash can or the like nearby, the user may have difficulty disposing of the used wet tissues or tissue paper. Thus, a package has been proposed that is provided with a used tissue paper storage section for storing used wet tissues (see, for example, Patent Document 1).
[0004] The package disclosed in Patent Document 1 comprises a package body in which multiple wet tissues are stored, and a used wet tissue storage section provided on the outer surface side of the package body. This package comprises a first sealed section formed by joining a pair of first side edges of a sheet member to each other, and a pair of second sealed sections formed by respectively joining a pair of side edges extending in a direction intersecting the pair of first side edges of the sheet member in a state in which the first sealed sections are formed. The used wet tissue storage section is composed of the first sealed section, a first sealed extension section formed by extending from the first sealed section in a direction intersecting the extension direction of the first side edges, and the sheet member that constitutes the package body.

[0012] Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings. The packaging body 1 of the embodiment shown in Figures 1 and 2 is formed from a sheet-like soft packaging material 10. The packaging body 1 is formed by joining a pair of side regions of a single rectangular sheet of soft packaging material 10 in a partially overlapping state to form the soft packaging material 10 into a cylindrical shape, and then joining end regions including two opening ends of the cylindrical soft packaging material 10.
[0013] The packaging body 1 has a substantially rectangular parallelepiped shape and has a first direction X and a second direction Y perpendicular to the first direction X. The first direction X coincides with the extending direction of a first sealed portion 21 described below, and also coincides with the longitudinal direction of the packaging body 1 in this embodiment. The second direction Y is perpendicular to the extending direction of the first sealed portion 21, and also coincides with the lateral direction of the packaging body 1 in this embodiment.
[0014] 1 and 2, the package 1 formed from the flexible packaging material 10 has a storage section 5 capable of storing an object 2. As shown in Fig. 2, the storage section 5 has a storage space 51 capable of storing the object 2. A stack 2S in which a plurality of objects 2 are stacked in an unfolded state or folded into a predetermined shape such as a rectangle is stored in the storage section 5. The storage object 2 may be, for example, a fiber sheet such as a nonwoven fabric impregnated with a liquid such as lotion, milky lotion, beauty essence, face wash, makeup remover, hair wash, disinfectant, detergent, activator water, alcohol-containing liquid, water, etc. Alternatively, a dry sheet such as tissue paper may be used as the storage object 2.
[0015] The storage section 5 has a first surface F1 and a second surface F2 which is the surface opposite to the first surface F1. The storage section 5 has a pair of third surfaces F3, F3 between the opposing first surface F1 and second surface F2. The pair of third surfaces F3, F3 face each other in the second direction Y. The storage section 5 has the first surface F1, the second surface F2, and the pair of third surfaces F3, F3 each formed of a soft packaging material 10.
[0016] The storage section 5 has a linear fold line (not shown) extending in the first direction X on the third surface F3, which is formed in the center of the height direction of the third surface F3, and the fold line is folded inward in the second direction Y to form a valley fold, so that the soft packaging material 10 forming the third surface F3 can be folded into a V shape. In this way, the storage section 5 has a gusset shape on the pair of third surfaces F3, F3.
[0017] As shown in Figs. 1 and 2, the storage section 5 has an opening 3 for taking out the storage object 2 and a cover sheet 4 for opening and closing the opening 3 on the first surface F1.
[0018] The opening 3 is a through hole penetrating the first surface portion F1 of the soft packaging material 10, and is located at the center of the first surface portion F1. The opening 3 communicates with the storage space 51 for the storage object 2 in the storage section 5. The storage object 2 is taken out to the outside through the opening 3. The shape of the opening 3 is not particularly limited, and may be, for example, a rectangular, square, circular, or elliptical shape. The opening 3 may be formed at least when the lid sheet 4 is lifted up. Therefore, the opening 3 may not be formed in the package 1 until the lid sheet 4 is lifted up for the first time, and when the lid sheet 4 is lifted up for the first time, a part of the first surface portion F1 is lifted up together with the lid sheet 4, so that the opening 3 is formed for the first time.
[0019] The lid sheet 4 covers the entire opening 3 on the outer surface of the first surface F1 and is peelably attached to the first surface F1. The lid sheet 4 may be a seal sheet having an adhesive layer made of an adhesive on the surface facing the first surface F1. The adhesive layer of the lid sheet 4 is preferably removable. In this case, the adhesive layer can be imparted with removable properties by forming the adhesive layer with an adhesive having removable properties. As such an adhesive, a general-purpose acrylic adhesive is preferable.
[0020] 2 and 4, the package 1 has a first sealed portion 21 formed along a first direction X by joining a pair of side regions of a rectangular soft packaging material 10 in a palm-to-palm shape. The storage section 5 also has a pair of second sealed portions 22, 22 at both ends in the first direction X. The second sealed portion 22 extends in a direction intersecting the first direction X, specifically in a direction perpendicular thereto. The first sealed portion 21 is located between the pair of second sealed portions 22, 22. In the manufacturing process of the package 1, the first sealed portion 21 is a joining portion that forms the rectangular soft packaging material 10 into a cylindrical shape, and joins side regions of the rectangular soft packaging material 10 together along the first direction X on the second surface portion F2 side. That is, the second surface portion F2 includes the first sealed portion 21. The first sealed portion 21 is located approximately in the center of the storage portion 5 in the second direction Y, but the position of the first sealed portion 21 is not limited thereto, and may be formed, for example, in a position offset outward from the center in the second direction Y. The first sealed portion 21 falls down to one side in the second direction Y and contacts the second surface portion F2. The second sealed portions 22, 22 are joining portions that close the openings located at both ends of the tubular soft packaging material 10, and together with the first sealed portion 21, form the storage portion 5 having a sealed storage space 51. That is, the second sealed portions 22, 22 are located on both sides of the tubular soft packaging material 10, and are formed in a pair of end regions that have openings. The first sealed portion and the second sealed portion 22 are formed by, for example, heat sealing.
[0021] As the soft packaging material 10 constituting the package 1, a liquid-impermeable sheet material can be used, and for example, a sheet material made of any one or more of aluminum sheets, thermoplastic resin films, thermoplastic resin films on which aluminum, silica, alumina, or the like is vapor-deposited, thermoplastic resin films serving as a sealant layer, and laminated films in which an aluminum layer is sandwiched between thermoplastic resin films can be used. The thermoplastic resin film may be a base film such as a polyethylene terephthalate (PET) film or a nylon film, or may have a laminated structure in which these films are laminated. From the viewpoint of suppressing the seepage or volatilization of the liquid contained in the object to be stored 2 (e.g., wet wipes), it is preferable that the soft packaging material 10 has a laminated structure in which an aluminum sheet, a PET film, or an aluminum layer is laminated. The thermoplastic resin layer in such a laminated structure may be a single layer, or may be a multilayer structure of two or more layers.
[0022] As shown in Figs. 1 and 2, the packaging body 1 includes a cover sheet 40. The cover sheet 40 is removably attached to the first surface F1 so as to cover at least a part of the first surface F1 before the packaging body 1 is used. For example, the cover sheet 40 is attached to the first surface F1 so as to cover at least the lid sheet 4. With this configuration, the lid sheet 4 is protected by the cover sheet 40 until immediately before use, so that the virginity of the lid sheet 4 is ensured until immediately before the user opens the lid sheet 4. As a result, an outer bag for protecting the packaging body, which has been used conventionally, is no longer necessary, and the amount of synthetic resin used can be reduced.
[0023] When using the object 2 contained in the package 1, the user peels the cover sheet 40 off the first surface portion F1, then opens the lid sheet 4 to expose the opening 3, and picks up the object 2 with his / her fingers through the opening 3 to remove it from the package 1.
[0024] As shown in FIG. 1, the cover sheet 40 is attached to the first surface F1 so that each side edge along the longitudinal direction of the cover sheet 40 coincides with each side edge along the longitudinal direction of the first surface F1. Also, the cover sheet 40 is attached to the first surface F1 so that each edge along the lateral direction of the cover sheet 40 coincides with the inner edge 22b (see FIG. 1) of each second seal portion 22. That is, the first surface F1 and the cover sheet 40 are both rectangular with the same dimensions. Therefore, the second surface F2, which is the surface opposite to the first surface F1, and the cover sheet 40 are also rectangular with approximately the same dimensions. In this way, as described later, the space S defined by the cover sheet 40 and the second surface F2 can be maximized, and a large amount of the storage object 2 after use can be stored in the space S. Such "approximately the same dimensions" includes cases in which the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the rectangular cover sheet 40 are the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the first surface F1 and the second surface F2, and cases in which they are shorter by within 10 mm. From the viewpoint of more reliably attaching the cover sheet 40 to the first surface F1, the length in the first direction X of the cover sheet 40 of this embodiment is preferably 3 mm or more, more preferably 5 mm or more shorter than the length in the first direction X of the first surface F1. From the same viewpoint as above, the length in the second direction Y of the cover sheet 40 of this embodiment is preferably 1 mm or more, more preferably 3 mm or more shorter than the length in the second direction Y of the first surface F1. By setting the cover sheet 40 to such dimensions, the cover sheet 40 can be more reliably attached to the first surface F1 even if the attachment position of the cover sheet 40 is shifted or the heat seal position is shifted during the manufacturing process of the package 1.
[0025] As shown in FIG. 3, the dimensions of the cover sheet 40 can be made approximately the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the object 2 to be stored, which is a rectangular item such as wet tissue or tissue paper. Such "approximately the same dimensions" includes cases in which the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the rectangular cover sheet 40 are the same as the vertical width (length in the first direction X) and horizontal width (length in the second direction Y) of the object to be contained 2, and cases in which they are shorter by within 10 mm. When wet tissues or tissue paper are stored in a folded state, the vertical and horizontal widths of the item (the object 2) refer to the dimensions when the item is folded. Setting the dimensions of the cover sheet 40 in this manner allows the user to feel a sense of unity between the cover sheet 40 and the object 2. Also, the cover sheet 40 has a smaller dimension than the second surface F2, and can be reattached to the planar area of the second surface F2 where the object 2 is located, making it easy to reattach the cover sheet 40 to the second surface F2.
[0026] 3, from the viewpoint of more reliably attaching the cover sheet 40 to the first surface F1, the length of the cover sheet 40 in the first direction X is preferably 1 mm or more shorter, and more preferably 3 mm or more shorter, than the length of the first direction X of the object to be contained 2. From the same viewpoint as above, the length of the cover sheet 40 in the second direction Y is preferably 1 mm or more shorter, and more preferably 3 mm or more shorter, than the length of the second direction Y of the object to be contained 2. By setting the cover sheet 40 to such dimensions, even if the attachment position of the cover sheet 40 is shifted during the manufacturing process of the package 1, the cover sheet 40 can be more reliably attached to the first surface F1. The packaging body 1 of the embodiment shown in FIG. 3 differs from the packaging body of the embodiment shown in FIG. 1 in that the third surface portion F3 does not have a gusset shape and has a flattened cylindrical shape.
[0027] 3, when the cover sheet 40 is a rectangle smaller than the dimensions of the first surface F1 and the second surface F2, the cover sheet 40 is preferably attached to the first surface F1 in the package 1 before use so as to be spaced inward in the first direction X from the inner edge 22b of the second sealed portion 22. In other words, it is preferable to provide a gap C1 between the cover sheet 40 and the inner edge 22b of the second sealed portion 22 in the first direction X (see FIG. 3). A plurality of packages 1 are housed and packed in a packing box such as a cardboard box. The packages 1 may be packed in the packing box with one second seal portion 22 facing downward and the other second seal portion 22 facing upward. In this packed state, the object 2 to be stored is shifted downward, so that the lower part of the package 1 near the second seal portion 22 is easily crushed. By providing the above-mentioned interval C1 against such crushing, the lower part of the cover sheet 40 can be prevented from wrapping around under the object 2 to prevent the cover sheet 40 from twisting or wrinkling. From the viewpoint of further preventing the cover sheet 40 from twisting or wrinkling in the packed state, the interval C1 (see FIG. 3) between the cover sheet 40 and the inner end edge 22b of the second seal portion 22 in the first direction X is preferably provided on one side of the second seal portion 22, and more preferably on the side of the second seal portion 22 that is arranged on the lower side in the packed state. The gap C1 may be provided on each side of the pair of second seal portions 22. From the same viewpoint as above, the distance C1 between the cover sheet 40 and the inner edge 22b of the second sealed portion 22 in the first direction X is preferably equal to or greater than half the thickness of the package 1 containing the object 2. The thickness of the package 1 is measured at the intersection of an imaginary line that bisects the overall length in the first direction X and an imaginary line that bisects the overall width in the second direction Y, i.e., at the center of the package 1.
[0028] As shown in FIG. 4(a) and FIG. 4(b), the cover sheet 40 has an adhesive-coated portion 42 formed by applying adhesive to the inner surface, which is the surface facing the first surface portion F1, so that a part of the adhesive is a non-adhesive-coated portion 43. In the inner surface of the cover sheet 40 of this embodiment, the adhesive-coated portion 42 is a portion where the adhesive is applied in a substantially annular shape, and the non-adhesive-coated portion 43 in the substantially annular portion is a missing portion where no adhesive is applied. For example, the adhesive-coated portion 42 has a rectangular ring shape or a circular ring shape (C-shape) with a missing part. On the inner surface of the cover sheet 40, the adhesive-coated portion 42 is formed in a peripheral area surrounding a portion that becomes the storage space S when the cover sheet 40 is attached to the second surface portion F2. The missing portion where no adhesive is applied in the peripheral area is the non-adhesive-coated portion 43. In other words, the adhesive is not applied to the portion surrounded by the adhesive-coated portion 42. The storage space S will be described later. Alternatively, after the adhesive is applied to the entire inner surface of the cover sheet 40 to form a coated surface, printing may be performed on the coated surface to form the adhesive-coated areas 42 and the adhesive-uncoated areas 43.
[0029] The adhesive-coated portion 42 of this embodiment is provided along the periphery of the cover sheet 40 (see FIG. 4). In detail, of the periphery of the four sides of the inner surface of the cover sheet 40, which is a rectangle, the periphery along two short sides is the first short-side adhesive-coated portion 421 and the second short-side adhesive-coated portion 422, and the periphery along one long side connecting these short sides is the long-side adhesive-coated portion 423. The periphery along the other long side is the adhesive-non-coated portion 43. Therefore, the adhesive-coated portion 42 is substantially U-shaped (substantially C-shaped) composed of the two short-side adhesive-coated portions 421, 422 and the long-side adhesive-coated portion 423 connecting these ends. In this way, of the periphery of the cover sheet 40 consisting of four sides, the periphery along three sides is the adhesive-coated portion 42, and the periphery along one side is the adhesive-non-coated portion 43. The cover sheet 40 has no adhesive applied to its outer surface, which is the surface not facing the first surface portion F1. From the viewpoint of adhesion, the width of the adhesive-coated portion 42 of the cover sheet 40 is preferably 3 mm or more, more preferably 5 mm or more, and more preferably 10 mm or more. From the viewpoint of peelability, the width of the adhesive-coated portion 42 is preferably 30 mm or less, more preferably 20 mm or less, and more preferably 15 mm or less. From the viewpoint of operability, it is preferable that the cover sheet 40 is attached to the first surface portion F1 so that the adhesive-coated portion 42 does not overlap with the lid sheet 4 before use of the package 1.
[0030] Each of the short-side adhesive-coated portions 421, 422 extends in the second direction Y (horizontal direction Y) with a constant width. Similarly, the long-side adhesive-coated portion 423 also extends in the first direction X (longitudinal direction X) with a constant width. The widths of the adhesive-coated portions 421, 422, 423 may be the same or different. When a non-adhesive-coated portion 43 is formed along the peripheral edge of one side of a rectangular cover sheet 40, the side 40a along which the non-adhesive-coated portion 43 is formed is also referred to as the non-coated side 40a. In the cover sheet 40 shown in Fig. 4, one of the long sides 40a of two opposing sides along the longitudinal direction is the non-coated side 40a.
[0031] 4(a), one edge of each of the short adhesive-coated portions 421, 422 on the two opposing sides, which is located on the side of the non-adhesive-coated portion 43, does not reach the long side 40a (non-coated side 40a) along the longitudinal direction of the cover sheet 40, but terminates before the long side 40a (non-coated side 40a) in the second direction Y. This has the advantage that when a user peels the cover sheet 40 from the first surface F1 of the package 1, the corners located on both sides of the non-coated side 40a can be easily grasped with the fingers, making it easier to peel the cover sheet 40.
[0032] 4(b), on the outer surface of the cover sheet 40 of this embodiment, i.e., the surface not facing the first surface portion F1, a peel start indicator 41 is provided in a position corresponding to at least one of the two ends of the non-adhesive-coated portion 43 extending in the first direction X, indicating the peel start position of the cover sheet 40. This allows the user of the package 1 to easily recognize the position to start peeling the cover sheet 40, and to perform the peeling operation accurately and easily. From the viewpoint of achieving such an effect, it is sufficient that the peel start indicator 41 is provided in a position corresponding to one of the four sides on the outer surface opposite the inner surface of the cover sheet 40 where the non-adhesive-coated portion 43 is formed. The peel start indicator 41 in this embodiment is an isosceles triangle, and the apex of the triangle is located at a corner of the cover sheet 40. The apex of this isosceles triangle peel start indicator 41 indicates the peel start position or peel direction of the cover sheet 40. Examples of the peel start indicator 41 include painting in a color different from the background color of the cover sheet 40, displaying letters, symbols, and / or figures, etc.
[0033] The cover sheet 40 may be transparent or opaque. In either case, the outer surface of the cover sheet 40 may be provided with a display related to the object 2 to be stored in the storage section 5. For example, a highly eye-catching design such as a product name, logo, image character, and / or catchy copy that recalls the object 2 may be provided on the outer surface of the cover sheet 40. Since the cover sheet 40 is made of a single flat sheet material, the sheet is less likely to bend or wrinkle compared to a case where a display is provided directly on the first surface F1 of the packaging body 1. Therefore, providing a display on the outer surface of the cover sheet 40 has the advantage that the packaging body 1 has a good appearance. However, this does not prevent a display from being provided on the first surface F1 of the packaging body 1. Therefore, for example, a display that is the same as or different from the display provided on the cover sheet 40 may be provided on the first surface F1 of the packaging body 1.
[0034] Whether the cover sheet 40 is transparent or opaque, instead of or in addition to applying various designs to the cover sheet 40, the space defined by the cover sheet 40 and the first surface portion F1 may contain flyers, samples, novelty goods, or the like bearing promotional messages to enhance the commercial value of the package 1.
[0035] With the cover sheet 40 attached to the first surface F1, it is preferable that the adhesive-coated portion 42 on the cover sheet 40 does not overlap with the lid sheet 4 (see Figs. 1 and 3). This effectively prevents the lid sheet 4 from unintentionally peeling off and the object 2 to be contained from being exposed through the opening 3 when the cover sheet 40 is peeled off from the first surface F1.
[0036] 5 to 7 show examples of how the packaging body 1 shown in FIG. 1 can be used. The cover sheet 40 is peeled off from the first surface F1 of the package 1 and attached to the second surface F2, so that a space S (see Figs. 6 and 7) is defined between the cover sheet 40 and the second surface F2. The cover sheet 40 is capable of storing an article in the space S through the non-adhesive coated portion 43. This will be described with reference to Figs. 5(a) to (c) and 6.
[0037] 5(a), the cover sheet 40 is peeled off from the first surface F1 of the package 1. At this time, the peeling operation can be easily performed by pinching the portion of the cover sheet 40 where the peeling start indicator 41 is present with two fingers and pulling up the cover sheet 40.
[0038] Next, as shown in Fig. 5(b), the package 1 is turned upside down so that the second surface F2 faces upward. In this state, the second surface F2 faces the inner surface of the cover sheet 40 (i.e., the surface on which the adhesive coating portion 42 is formed). Then, as shown in Fig. 5(c), the cover sheet 40 is attached to the second surface F2. When attaching the cover sheet 40, the attachment position of the cover sheet 40 is determined using a target mark 50 provided on the surface of the second surface F2 as a guide, as shown in Fig. 5(b). In other words, the target mark 50 is an indication that indicates the appropriate attachment position of the cover sheet 40 on the second surface F2.
[0039] 5(b), the target mark 50 is substantially L-shaped and is provided at a position that coincides with a pair of adjacent corners 47, 48 of the cover sheet 40 when the cover sheet 40 is attached in an appropriate position on the second surface portion F2. Specifically, the target marks 50 are provided in two places: at the corner 47 at the intersection of the first short-side adhesive-coated portion 421 and the long-side adhesive-coated portion 423 of the cover sheet 40, and at the corner 48 at the intersection of the second short-side adhesive-coated portion 422 and the long-side adhesive-coated portion 423.
[0040] Using the two target marks 50, 50 shown in Fig. 5(b) as guides, the cover sheet 40 is attached to the second surface portion F2 as shown in Fig. 5(c). When attachment is complete, the positions of the two long sides 40a, 40b of the cover sheet 40 approximately coincide with the positions of the two long sides F2a, F2b of the second surface portion F2 as shown in Fig. 5. Furthermore, as shown in Fig. 5(c), the positions of the two short sides 40c, 40c of the cover sheet 40 approximately coincide with the positions of the inner edges 22b, 22b of the second seal portion 22.
[0041] When the attachment operation of the cover sheet 40 to the second surface portion F2 is completed in this manner, a space S is defined by the cover sheet 40 and the second surface portion F2, as shown in Fig. 6. An article can be stored in this space S through the non-adhesive coated portion 43. In this way, according to the packaging body 1, the cover sheet 40 used for the purpose of ensuring the virginity of the lid sheet 4 is also used as a member for forming the storage space S for the item, so there is no need to prepare a separate member for forming the space S. From this point of view, the packaging body 1 makes it possible to reduce the amount of resin used. In addition, since the used storage object 2 can be stored in the storage space S, it is highly convenient (see FIG. 7). 7 shows a state in which a used storage object 2 is stored in the storage space S. The item stored in the storage space S is not limited to the used storage object 2, and may be other garbage or the like.
[0042] Various indications can be provided on the surface of the second surface F2. For example, a package insert showing the efficacy or ingredients of the contained object 2 can be provided. It is technically possible to display the package insert on the first surface F1, but in that case, the package insert would be covered by the cover sheet 40. Therefore, it is preferable to display the package insert on the second surface F2. The cover sheet 40 is attached to the second surface F2, but since this is when the package 1 is in use, it does not matter if the package insert is covered by the cover sheet 40 and cannot be seen. In fact, since package inserts are often indications with poor design, it is advantageous in terms of enhancing the design of the entire package 1 to have the package insert covered by the cover sheet 40, which is a member with a high design quality.
[0043] The adhesive strength of the adhesive-coated portion 42 of the cover sheet 40 is preferably such that it can be easily peeled off from the first surface portion F1 by pulling it lightly, and that it will not peel off in its natural state (when no external force is applied) after it is attached to the second surface portion F2. This can further improve the operability of the cover sheet 40. The adhesive strength of the adhesive-coated portion 42 can be measured as the peel strength of the cover sheet 40. From the standpoint of further improving operability, the peel strength of the cover sheet 40 is preferably within the following range. From the viewpoint of preventing unintentional peeling at a storefront or the like, the peel strength of the cover sheet 40 from the first surface portion F1 is preferably 1 N or more and 100 N or less, more preferably 2 N or more and 90 N or less. From the viewpoint of facilitating peeling during use, the peel strength of the cover sheet 40 from the first surface portion F1 is preferably 0.1 N or more and 50 N or less, more preferably 0.5 N or more and 30 N or less. From the viewpoint of making it easier to reattach the cover sheet 40 to the second surface portion F2, the peel strength of the cover sheet 40 from the second surface portion F2 is preferably 0.1 N to 70 N, more preferably 0.5 N to 50 N. From the viewpoint of improving the resistance to peeling when a used storage object 2 is stored in a state in which the cover sheet 40 is attached to the second surface portion F2, the peel strength of the cover sheet 40 from the second surface portion F2 is preferably 2 N to 200 N, more preferably 3 N to 150 N. The peel strength from the second surface portion F2 is the strength when the cover sheet 40 peeled from the first surface portion F1 is attached to the second surface portion F2 and then the cover sheet 40 is peeled from the second surface portion F2. The peel strength is measured by the following method.
[0044] [Method of measuring peel strength] A hole with a diameter of 6 mm is opened at any position in the adhesive non-coated portion 43 of the cover sheet 40 attached to the first surface F1 or the second surface F2. A hook-shaped jig is then hooked onto the hole, and a force gauge connected to the jig is used to measure the maximum strength when the cover sheet 40 is peeled off from the first surface F1 or the second surface F2, which is the peel strength. When the cover sheet 40 is attached to the first surface F1 from the beginning, the cover sheet 40 is attached to the second surface F2 and left to stand for one day in an environment at 20°C, and then the peel strength from the second surface F2 is measured by the above-mentioned method. When the cover sheet 40 is attached to the second surface F2 from the beginning, the cover sheet 40 is attached to the first surface F1 and left to stand for one day in an environment at 20°C, and then the peel strength from the first surface F1 is measured by the above-mentioned method. If the inner surface of the cover sheet 40 has an easily peelable joint 73, as described below, a piece of paper or the like is attached to the easily peelable joint 73 to neutralize the adhesive force of the easily peelable joint 73, and then the above measurement is performed.
[0045] The peel strength can be adjusted by either the type of adhesive or the area or dimensions of the adhesive-coated portion 42 . For example, the adhesive forming the adhesive-coated portion 42 is preferably an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber adhesive, or the like. To make it easier to keep the peel strength within the aforementioned range, the area of adhesive-coated portion 42 is preferably 3% to 50%, and more preferably 10% to 30%, of the area of cover sheet 40. The area of adhesive-coated portion 42 is the area of the portion of the inner surface of cover sheet 40 where adhesive is present, and does not include the area of adhesive-uncoated portion 43. The width of adhesive-coated portion 42 may be within the range described above. Furthermore, adhesive-coated portion 42 is preferably shaped like the letter C, or a trapezoid having a missing portion (non-adhesive-coated portion 43) on the upper side.
[0046] As shown in Fig. 6, the packaging body 1 is advantageously configured such that, when the cover sheet 40 is attached to the second surface F2, the attachment directionality of the cover sheet 40 is determined so that the non-adhesive-coated portion 43 is positioned in the opposite direction to the collapse direction i (the leftward direction on the paper in Fig. 6) of the first sealed portion 21. By attaching the cover sheet 40 to the second surface F2 in such a directionality, the operation of storing the used storage object 2 in the space S is less likely to be hindered by the first sealed portion 21, as shown in Fig. 7.
[0047] An example of a configuration applied to the package 1 to uniquely determine the attachment direction of the cover sheet 40 to be attached to the second surface F2 is to provide an indication (not shown) indicating the attachment direction on the second surface F2. That is, it is advantageous to provide an indication on the second surface F2 or the cover sheet 40 indicating that the cover sheet 40 is attached to the second surface F2 so that the non-adhesive coated portion 43 is positioned in the opposite direction to the collapse direction of the first seal portion 21. More specifically, when a used storage object 2 is stored in the space S, the storage object 2 is prevented from getting stuck on the first seal portion 21, which is advantageous in terms of operability during storage.
[0048] The packaging body 1 and its constituent members of the present invention are not limited to the embodiment shown in Figures 1 to 7. Another embodiment of the packaging body 1 and its constituent members of the present invention will be described below. In the following, the other embodiment will be described mainly with respect to the constituent parts different from the embodiment shown in Figures 1 to 7, and similar constituent parts will be given the same reference numerals and will not be described. For constituent parts that are not particularly described, the description of the embodiment shown in Figures 1 to 7 will be applied as appropriate.
[0049] In the cover sheet 40A of the present embodiment described above, the short-side adhesive-coated portions 421, 422 extending in the second direction Y in the adhesive-coated portion 42 do not reach the non-coated side 40a, but the present invention is not limited to such a configuration. The cover sheet 40A shown in Figs. 8(a) and (b) has adhesive-coated portions 421, 422 on two opposing sides, and among the edges of these adhesive-coated portions 421, 422, the edge located on the adhesive-non-coated portion 43 side reaches the edge (non-coated side 40a) of the cover sheet. In other words, the short-side adhesive-coated portions 421, 422 extend over the entire width of the cover sheet 40 in the second direction Y. This makes it possible to further suppress peeling of the cover sheet 40A at the second surface portion F2.
[0050] The cover sheet 40A of the present embodiment has on its inner surface a display 44 indicating information regarding how to use the cover sheet 40A. The display 44 on the inner surface of the cover sheet 40A will hereinafter also be referred to as the "inner surface display 44." The information regarding how to use the cover sheet 40A included in the inner surface display 44 is information regarding a method of forming a space S defined by the cover sheet 40A and the second surface F2 by attaching the cover sheet 40A to the second surface F2, and is information indicating the method using characters, figures, images, or the like. In addition to the above information, the inner surface display 44 may include information about the package or the object 2. This information may be a two-dimensional bar code, a URL, or the like. When displaying information such as the information on the usage method on the inner surface of the cover sheet 40A, the entire inner surface of the cover sheet 40A may be coated with adhesive to form a coated surface, and the display may then be printed on the coated surface to form the non-adhesive coated portion 43 and the substantially U-shaped (substantially C-shaped) adhesive coated portion 42. Alternatively, a resin film layer may be attached on the coated surface to form the non-adhesive coated portion 43 and the substantially U-shaped (substantially C-shaped) adhesive coated portion 42, and the display may then be printed on the surface of the film layer.
[0051] In addition, in the cover sheet 40A of this embodiment, the peel start indicator 41 is provided at a position corresponding to the non-coated side 40a where the non-adhesive coated portion 43 is formed among the four sides on the outer surface of the cover sheet 40, but the position of the peel start indicator 41 among the positions corresponding to the non-coated side 40a is different from the form shown in FIG. 4 (see FIG. 8(b)). More specifically, the peel start indicator 41 of this embodiment is not present at the corners on both sides of the non-coated side 40a, but is provided at a position adjacent to the adhesive coated portion 421, which is on the inside in the first direction X of one of the short adhesive coated portions 421 extending in the second direction Y. In this way, the peel start indicator 41 is positioned on the inside in the first direction X of the adhesive coated portion 421 extending in the second direction Y, so that the peel start indicator 41 can be more reliably guided to start peeling from the non-adhesive coated portion 43, and the peel operation of the cover sheet 40A can be more easily performed.
[0052] 9(a) to (d) show variations in the position of the peel start indicator 41. 9(a), the peel start indication 41 does not have to be adjacent in the first direction X to the adhesive-coated portions 421, 422 extending in the second direction Y. The peel start indication 41 shown in FIG. 9(a) is located at the center in the first direction X of the adhesive-uncoated portion 43 extending in the first direction X. The peel start indicator 41 shown in Figures 8 and 9(a) is provided in a position that does not overlap with the adhesive coated portion 42, but as shown in Figures 9(b) to (d), the peel start indicator 41 may overlap with the adhesive coated portion 42 partially or entirely. The peel start indication 41 shown in Figure 9 (b) has an isosceles triangle with its apex facing inward in the second direction Y and overlapping with the inner edge of the short-side adhesive coated portion 421 in the first direction X, and the outer half of the triangle facing in the first direction X overlaps with the short-side adhesive coated portion 421. The peel start mark 41 shown in FIG. 9(c) overlaps with the short-side adhesive-coated portion 421 with the apex of the isosceles triangle facing inward in the first direction X. The peel start indicator 41 shown in FIG. 9(d) overlaps with the short-side adhesive-coated portion 421 with one equal side and the apex of the isosceles triangle being located on the non-coated side 40a.
[0053] 10(a) and (b) has a closing means 70 that at least partially closes an opening formed between the non-adhesive-coated portion 43 and the first surface portion F1 of the cover sheet 40B. Such an opening is a gap between the cover sheet 40 and the first surface portion F1 in the non-adhesive-coated portion 43. Closing by the closing means 70 can ensure that the cover sheet 40B remains unpeeled or that the lid sheet 4 remains unopened. The closing means 70 in this embodiment is a tack seal 71 having a perforation 72. The perforation 72 and the uncoated edge 40a of the tack seal 71 overlap, and the tack seal 71 is attached across the uncoated edge 40a to the cover sheet 40 and the first surface F1. When the cover sheet 40B is peeled off from the first surface F1 of the package 1b, the tack seal 71 is torn along the perforation 72 (see FIG. 10(b)). Whether or not the cover sheet 40B has been peeled off (virginity) can be indicated by the presence or absence of this tear. The tack seal 71 may have a shape such as an ellipse that is long in the second direction Y. In this case, when the cover sheet 40B is attached to the second surface F2 to form a space S defined by the cover sheet 40B and the second surface F2, the tack seal 71 that is long in the second direction Y may be used to close an opening on the side of the adhesive non-coated portion 43, which serves as an entrance to the space S.
[0054] Variations of the closure means 70 are shown in Figures 11(a)-(d) and 12. 11(a) to (d) is an easily peelable joint 73, which joins the cover sheet 40B and the first surface F1 at the non-adhesive-coated portion 43. The easily peelable joint 73 is a portion where the cover sheet 40B and the first surface F1 are joined, and the area where the adhesive is present is smaller than the adhesive-coated portion 42, so that the joining at the easily peelable joint 73 can be easily released. The easily peelable joint 73 may be formed by printing on the portion where the adhesive is coated, to provide portions covered with the adhesive and portions not covered with the adhesive. 11(a) to (c) are rectangular in plan view, and are formed partially in the non-adhesive-coated portion 43. In this case, the package may have a single easily peelable joint 73 (see FIGS. 11(a) and (c)), or may have a plurality of easily peelable joints 73 (see FIGS. 11(a) and (c)). As shown in Figures 11(a) and (b), the easy peelable bonding portion 73 may be provided in a position in the non-adhesive-coated portion 43 that does not overlap with the peel start indicator 41. Alternatively, only the easy peelable bonding portion 73 may be provided in the non-adhesive-coated portion 43 (see Figures 11(c) and (d)). Alternatively, as shown in Figure 11(d), the easy peelable bonding portion 73 may extend continuously over the entire length of the non-adhesive-coated portion 43 in the first direction X.
[0055] The closing means 70 shown in FIG. 12 is a breakable joint 75 formed along the non-coated side 40a of the cover sheet 40B. The breakable joint 75 is a long piece portion of the cover sheet 40B that extends outward in the second direction Y beyond the non-adhesive-coated portion 43, is continuous with the cover sheet 40B via a perforation, and extends in the first direction X. The breakable joint 75 is also bonded to the first surface portion F1 over its entire area. The cover sheet 40B shown in FIG. 12 has the breakable joint 75 and a peeling extension portion 431 that extends outward in the first direction X beyond the short-side adhesive-coated portion 421. The breakable joint 75 is also formed in the peeling extension portion 431 and is continuous over the entire length of the cover sheet 40B in the first direction X, including the peeling extension portion 431. 12, the non-coated side 40a is formed by peeling the cover sheet 40B from the first surface portion F1 while tearing the cover sheet 40B along the perforation while gripping the peel-off extension 431. By this tearing, the cover sheet 40B is separated from the tear joint 75, while the tear joint 75 remains on the first surface portion F1.
[0056] In the embodiment shown in Figures 9 to 12, the opening formed between the non-adhesive coated portion 43 and the first surface portion F1 is at least partially closed by the closing means 70, but as shown in Figures 1 to 8, the packaging body does not need to be provided with the closing means 70.
[0057] In a manufacturing process described later, the cover sheet 40 is attached to the flexible packaging material 10 via the adhesive coating section 42, and then the flexible packaging material 10 is shaped into a cylinder to form the first sealed section 21. Before the first sealed section 21 is formed, the flexible packaging material 10 with the cover sheet 40 attached thereto is conveyed by a conveying roll. During this transport, air may get between the cover sheet 40 and the flexible packaging material 10 from the non-adhesive coated portion 43, causing wrinkles in the cover sheet 40. In particular, when the flexible packaging material 10 is introduced between a pair of transport rolls, the cover sheet 40 is prone to wrinkles due to the air getting in. From the viewpoint of suppressing the infiltration of air and further suppressing the occurrence of wrinkles, it is preferable that the cover sheet 40 has a structure shown in FIG. The cover sheet 40C shown in FIG. 13(a) has an adhesive-coated portion 42 that is substantially U-shaped, and an adhesive-free portion 43 is formed on the periphery along one of the short sides of the cover sheet 40C. The adhesive-coated portion 42 is formed by longitudinal adhesive-coated portions 423, 424 provided on the periphery along a pair of long sides of the cover sheet 40C, and a transverse adhesive-coated portion 422 provided on the periphery along the other short side. The adhesive-free portion 43 faces the transverse adhesive-coated portion 422 in the first direction X. When the conveying direction of the flexible packaging material 10 corresponds to the first direction X, the cover sheet 40C shown in FIG. 13(a) is less likely to let air in through the adhesive-free portion 43, and wrinkles can be further suppressed.
[0058] The cover sheet 40C shown in Fig. 13(b)-(c) has an approximately U-shaped adhesive-coated portion 42 provided on the periphery along the three sides of the cover sheet 40C, and an adhesive-free portion 43 provided on the periphery along one long side of the cover sheet 40C. The adhesive-coated portion 42 is formed by a long-side adhesive-coated portion 423 provided on the periphery along one long side of the cover sheet 40C, and short-side adhesive-coated portions 421, 422 provided on the periphery along a pair of short sides. The cover sheet 40C shown in Fig. 13(b)-(d) has a circular easy-peel joint portion 73 spaced apart from one long side of the cover sheet 40C, which makes it more difficult for air to enter through an opening formed between the adhesive-free portion 43 and the first surface portion F1.
[0059] 13(b) is located in the non-adhesive-coated portion 43. From the viewpoint of further suppressing air from entering through the non-adhesive-coated portion 43, it is preferable that the cover sheet 40C has the following configuration. The distance L1 (see FIG. 13(b)) between the easily peelable joint 73 and the uncoated edge 40a in the second direction Y is preferably 3% to 60%, and more preferably 8% to 30%, of the length LY (see FIG. 13(b)) in the second direction Y of the portion of the cover sheet 40C that forms the storage space S. The "portion of the cover sheet 40C that forms the storage space S" refers to the portion of the cover sheet 40C where no adhesive is applied, including the uncoated adhesive portion 43. The distance L1 (see FIG. 13(b)) is preferably 3 mm or more and 30 mm or less, and more preferably 10 mm or more and 20 mm or less. The shortest distance L2 (see FIG. 13(b)) between the easily peelable joint 73 and the adhesive-coated parts 421, 422 in the first direction X is preferably 5% or more and less than 50%, and more preferably 20% or more and less than 50%, of the length LX (see FIG. 13(b)) in the first direction X of the part of the cover sheet 40C that forms the storage space S. The shortest distance L2 is the shortest distance between each of the pair of adhesive-coated parts 421, 422 and the easily peelable joint 73 in the first direction X. The shortest distance L2 (see FIG. 13(b)) is preferably 5 mm or more and less than 50 mm, and more preferably 10 mm or more and less than 50 mm.
[0060] 13(c) has an easily peelable bonding portion 73a located in the non-adhesive-coated portion 43, and also has an easily peelable bonding portion 73b (hereinafter also referred to as an "inner bonding portion 73b") located inward in the second direction Y from the easily peelable bonding portion 73a. Such a cover sheet 40C has two inner bonding portions 73b, 73b located approximately in the center in the second direction Y and spaced apart in the first direction X. 13(d) has a plurality of easily peelable bonding portions 73a and an inner bonding portion 73b. The cover sheet 40C has one inner bonding portion 73b located approximately in the center in the second direction Y and spaced apart in the first direction X.
[0061] In order to suppress the occurrence of wrinkles in the cover sheet 40C due to transport while further improving operability when peeling the cover sheet 40C from the first surface portion F1, it is preferable that the easily peelable joint 73, including the inner joint 73b, has the following configuration. The area of each easily peelable joint 73 is preferably 0.01% to 10%, and more preferably 0.1% to 5%, of the area of the portion forming the storage space S of the cover sheet 40C. The area of each of the easy peelable joints 73 is preferably 5 mm 2 or more and 100 mm 2 or less, and more preferably 10 mm 2 or more and 30 mm 2 or less. The area of the easily peelable bonding portion 73 is preferably 1% to 50%, and more preferably 10% to 30%, of the area of the portion of the cover sheet 40C that forms the storage space S. As shown in Figures 13(c) and (d), when the cover sheet 40C has a plurality of easily peelable bonding portions 73, the above-mentioned "area of the easily peelable bonding portions 73" refers to the total area of the plurality of easily peelable bonding portions 73. The separation distance L3 in the second direction Y between the easily peelable joint 73a and the inner joint 73b (see Figure 13(c)) is preferably 5% or more and 50% or less, and more preferably 10% or more and 30% or less, of the length LY in the second direction Y of the portion of the cover sheet 40C that forms the storage space S (see Figure 13(c)). The distance L3 is preferably 5 mm or more and 50 mm or less, and more preferably 10 mm or more and 30 mm or less. In addition, from the viewpoint of further improving operability when peeling off the cover sheet 40C from the first surface portion F1, it is preferable that the easily peelable joint portion 73a and the inner joint portion 73b do not overlap in the first direction X (see Figures 13(c) and (d)).
[0062] When the cover sheet 40C has short-side adhesive-coated portions 421, 422 provided on the periphery along a pair of short sides, from the viewpoint of achieving both releasability from the first surface portion F1 and attachability to the second surface portion F2, it is preferable that one of the short-side adhesive-coated portions of the cover sheet 40C does not reach the non-coated side 40a (see FIG. 14). That is, one of the short-side adhesive-coated portions 422 terminates before the non-coated side 40a in the second direction Y, and the other short-side adhesive-coated portion 421 reaches the non-coated side 40a. In this case, a portion 425 between the short-side adhesive-coated portion 422 that does not reach the non-coated side 40a on the outer surface of the cover sheet 40C and the non-coated side 40a can be the peel start portion 425 of the cover sheet 40C. The cover sheet 40C of this embodiment may be provided with a peel start indicator 41 at a position corresponding to the peel start portion 425 on its outer surface (not shown in FIG. 14).
[0063] 15, the cover sheet 40D has an inner surface indicator 44a on the inner surface for aligning the attachment position of the cover sheet 40D with the target mark 50. The cover sheet 40D has a longitudinal adhesive-coated portion 423 connected to a pair of transverse adhesive-coated portions 421, 422, and an inner surface indicator 44a is located at each of two corners formed by the inner edge in the second direction Y of the longitudinal adhesive-coated portion 423 and the inner edge in the first direction X of the transverse adhesive-coated portions 421, 422. The cover sheet 40D is attached at the appropriate position on the second surface F2 by arranging the inner surface indicator 44 and the target mark 50 provided on the second surface F2 so as to overlap each other.
[0064] As shown in Figures 13 to 15, the cover sheets 40C and 40D may be rectangular with rounded corners, and as shown in Figures 8 to 12, the cover sheets 40A and 40B may be rectangular with right-angled corners.
[0065] 16 has an opening 3a for removing the object 2 on the second surface F2 including the first seal portion 21. The first surface F1 of this embodiment does not have an opening for removing the object 2. The opening 3a in this embodiment is a slit-shaped opening extending in the first direction X, and is provided with a chuck mechanism having interlocking protrusions and recesses. This chuck mechanism allows the opening 3a in this embodiment to be opened and closed freely. The opening 3a in this embodiment is formed outward in the second direction Y from the first seal portion 21, but the position of the opening 3a is not particularly limited.
[0066] The packaging body 1d of this embodiment includes a cover sheet 40 attached so as to cover at least a part of the surface opposite to the surface F2 in which the opening 3a is formed. More specifically, the packaging body 1d of this embodiment includes a cover sheet 40 attached to the first surface F1 opposite to the second surface F2 in which the opening 3a is formed (see FIG. 16). In the packaging body 1d of this embodiment, the cover sheet 40 is attached to the first surface portion F1 before use. The cover sheet 40 may be attached to the first surface portion F1 in a detachable manner, or may be attached to the first surface portion F1 in a non-detachable manner. In either case, in the packaging body 1d of this embodiment, a space S is formed between the cover sheet 40 and the first surface portion F1, and an article can be stored through the non-adhesive coated portion 43, as in the above-mentioned embodiment. That is, in the packaging body 1d of this embodiment, the cover sheet 40 is not reattached.
[0067] The packaging body in which the cover sheet 40 is attached to the surface opposite to the surface in which the opening for removing the storage object 2 is formed is not limited to the form shown in Fig. 16. For example, the surface in which the opening is formed is the first surface F1, and the surface to which the cover sheet 40 is attached is the second surface F2.
[0068] The package 1f shown in FIG. 17 is taller than the packages of the above-mentioned embodiments. That is, the height (length in the height direction) of the third surface F3 is taller than the packages of the above-mentioned embodiments. The package 1f shown in FIG. 17 is illustrated with the second surface F2 having the first seal portion 21 (not shown in FIG. 17) as the ground surface, and an opening 3 is formed in the first surface F1, and the opening 3 is closed by a lid sheet 4. The package 1f of this embodiment has a hexahedral shape, and the storage section 5 has, between the first surface F1 and the second surface F2, a pair of third surfaces F3, F3 facing the second direction Y, as well as a pair of fourth surfaces F4, F4 facing the first direction X. These third surface F3 and fourth surface F4 are side surfaces located between the first surface F1 and the second surface F2 of the package 1f. The fourth surface portion F4 is formed by folding end regions extending outward in the first direction X from each of the first surface F1 and the second surface F2 toward the inside side in the first direction X (the storage section 5 side). More specifically, in the soft packaging material 10, the first extending portion 24 extending outward in the first direction X from the first surface portion F1 and the second extending portion 25 extending outward in the first direction X from the second surface portion F2 are joined in a palm-to-palm shape by the second seal portion 22 at their outer ends in the first direction X, and the fourth surface portion F4 is formed by folding the first extending portion 24 and the second extending portion 25 toward the second surface portion F2. The first extending portion 24 is folded toward the second surface portion F2 along the second direction Y at an edge connected to the first surface portion F1. As a result, the outer surface of the fourth surface F4 is formed by the first extending portion 24. The second extending portion 25 is folded along the second direction Y at an edge connected to the second surface portion F2, and is further folded along the second direction Y at a portion 25a (hereinafter also referred to as the "outward folded portion 25a") that is outward in the first direction X from the folded portion. The second extending portion 25 has an end portion outward in the first direction X from the outward folded portion 25a folded toward the second surface portion F2, and the second extending portions 25 face each other. The opposing second extending portions 25 are joined to each other by an adhesive.
[0069] The package 1f shown in FIG. 17 has a cover sheet 40 on one of the third surfaces F3. In this way, the cover sheet 40 may be peelably attached so as to cover at least a part of one of the third surfaces F3. The cover sheet 40 of this embodiment is arranged on the third surface F3 so that the non-adhesive coated portion 43 faces the first surface F1. With this, with the second surface F2 as the ground surface, a storage space S is formed with an opening at the top (first surface F1 side) at the non-adhesive coated portion 43, so that the used storage object can be stored in the storage space S. Alternatively, the cover sheet 40 may be peeled off from the third surface F3 and then attached to either the second surface F2 or the fourth surface F4 for use. 17, the cover sheet 40 is removably attached to cover at least a portion of either the third surface portion F3, but instead, the cover sheet 40 may be removably attached to either the side surface of the third surface portion F3 or the fourth surface portion F4 so as to cover at least a portion of that surface. Also, multiple cover sheets 40 may be attached to one or more of the side surfaces F3, F4 of the storage portion 5. Furthermore, the packaging body 1f may include multiple cover sheets 40, with each cover sheet 40 attached to a different surface among the first surface F1, the second surface F2, the third surface F3, and the fourth surface F4. For example, the packaging body 1f may include a cover sheet 40 on the second surface F2, and another cover sheet 40 on any one of the third surfaces F3.
[0070] The packaging body in the above-described embodiment has the first sealed portion 21 formed by joining a pair of side regions of a sheet of soft packaging material 10 in a palm-to-palm shape, but is not limited to this form. For example, the first sealed portion 21 may be formed by overlapping the edges of a pair of side regions of a sheet of soft packaging material 10 while shifting them in the second direction Y, and then joining the overlapped portions. In this case, the first sealed portion 21 forms one side edge of the packaging body 1 along the first direction X, and is integrated with the second surface portion F2. The package may be one in which the edges of one sheet of soft packaging material 10 folded in half are sealed on three sides to form a first sealed portion 21 and a pair of second sealed portions 22. Alternatively, the package may be one in which two sheets of soft packaging material 10 are overlapped and their edges are sealed on all four sides to form a pair of first sealed portions 21 and a pair of second sealed portions 22. A package having the first sealed portion 21 and the second sealed portion 22 formed by sealing on three or four sides has three or four sides of the edge of the package sealed in a plan view. In this case, the first surface portion F1 and the second surface portion F2 each include the first sealed portion 21 and the second sealed portion 22, respectively.
[0071] Next, a preferred method for producing the package of the present invention will be described using a method for producing the package 1 shown in FIG. 1 as an example. The manufacturing method of this embodiment includes a cutting step of forming an opening 3 in a sheet of soft packaging material 10, a lid attachment step of attaching a lid sheet 4 to the soft packaging material 10 so as to cover the opening 3, an attachment step of attaching a cover sheet 40 to the soft packaging material 10 after the lid attachment step, a tubular body formation step of joining the side regions of the soft packaging material 10 together in a folded shape to form a tubular shape after the attachment step, and an end joining step of joining end regions, which are both ends of the tubular body made of the soft packaging material 10 on which the first sealed portion 21 has been formed, to form a pair of second sealed portions 22.
[0072] In the manufacturing method of this embodiment, a pasting step is performed on the flexible packaging material 10 after the cutting step and the lid pasting step, i.e., on the flexible packaging material 10 in which the opening 3 is formed and the lid sheet 4 covering it is pasted. In the pasting step, a cover sheet 40 is pasted to a location corresponding to the first surface portion F1 of the flexible packaging material 10. An adhesive-coated portion 42 and an adhesive-uncoated portion 43 are formed in the cover sheet 40 in advance, and the cover sheet 40 is pasted to the first surface portion F1 by adhesion of the adhesive-coated portion 42. In the cylindrical body forming step, the side regions of the soft packaging material 10 are joined together in a palm-to-palm manner with the contents 2 (laminate 2S) placed on the soft packaging material 10 after the pasting step, thereby forming the first sealed portion 21. In the cylindrical body forming step of this embodiment, the joining is performed by heat sealing processing. In the tubular body forming step, linear folds extending in the first direction X are formed in the tubular body at locations corresponding to the third surface portions F3, thereby making it possible to give the tubular body a gusset-like shape.
[0073] In the end joining step, the end regions of the cylindrical body are joined to close the openings of the end regions. In this embodiment, the end regions are joined by a heat sealing process. This forms a pair of second sealed portions 22 and also forms the storage portion 5 containing the object 2 to be stored. Through the above steps, the package 1 shown in FIG. 1 is manufactured.
[0074] As described above, the present invention is not limited to the above-described embodiment and can be modified as appropriate. In addition, the above-described embodiments may be combined. For example, in the above embodiment, the ends of the first and second short-side adhesive-coated portions 421, 422 provided on the cover sheet 40 are connected to the long-side adhesive-coated portion 423 to form a continuous, approximately C-shaped adhesive-coated portion 42. However, instead, as long as the items contained in the space S do not fall out, the short-side adhesive-coated portions 421, 422 and the long-side adhesive-coated portion 423 may not be connected to each other, and each of the adhesive-coated portions 421, 422, 423 may be individually independent. In addition, the non-adhesive coated portion 43 on the cover sheet 40 is provided on the peripheral edge portion of one side of the cover sheet 40 along the first direction X, but it may also be provided on the peripheral edge portion of one side of the cover sheet 40 along the second direction Y. Furthermore, the adhesive-coated portion 42 may be provided in a portion other than the peripheral portion of the cover sheet. For example, in a plan view of a rectangular cover sheet, the adhesive-coated portion 42 may be provided 10 mm or more inward from the peripheral edges of the four sides.
[0075] In the above embodiment, each of the adhesive-coated portions 421, 422, 423 is formed by continuously applying the adhesive, but instead, the adhesive may be intermittently applied to form each of the adhesive-coated portions 421, 422, 423 to the extent that the articles contained in the space S do not fall off. Examples of intermittent application include adhesive-coated portion 42 in which the adhesive is applied in a stripe, spiral, or dashed line shape.
[0076] In the above embodiment, the target marks 50 are provided in two places on the second surface portion F2, but the number of target marks is not limited to this, and may be, for example, one place, or three or more places. Also, the shape of the target mark 50 is not limited to that shown in FIG. 4(b). The pair of second sealed portions 22, 22 may have the same or different lengths (vertical widths) in the first direction X. In the latter case, a hanging hole for hanging and displaying the package 1 may be formed in the second sealed portion 22 having the longer vertical width.
[0077] In the above embodiment, one cover sheet 40 is attached to the first surface portion F1, but instead, two or more cover sheets, which may be the same or different, may be attached. Examples of such a configuration include those shown in Figures 18(a) to 18(d). Each of the packages 1e shown in Figures 18(a) to (d) includes two cover sheets 40. The non-adhesive coated portions 43 of these cover sheets 40 are formed on one of two sides along the first direction X of the attachment surface (not shown) of the storage section 5 to which the cover sheet 40 is attached. The attachment surface is the first surface portion F1 or the second surface portion F2. In the packaging body 1e shown in Fig. 18(a), two cover sheets 40 of the same shape and size are arranged in parallel along the first direction X. The outlines of the two parallel cover sheets 40 and the application surfaces are approximately the same in area and shape. In the packaging body 1e shown in Fig. 18(a), two spaces S are formed between the cover sheets 40 and the application surfaces. In a package 1e shown in FIGS. 18(b) to (d), two cover sheets 40 are arranged so as to overlap partially or entirely. In the packaging body 1e shown in Fig. 18(b), two cover sheets 40 of the same shape and size are arranged in a partially overlapping state in the first direction X. In the packaging body 1e shown in Fig. 18(b), a space S is defined by one cover sheet 40 and the attachment surface, and a space S is defined by one cover sheet 40, the other cover sheet 40 and the attachment surface. The packaging body 1e shown in Fig. 18(c) has two cover sheets 40 of the same shape and size arranged in a generally overlapping state. In the packaging body 1e shown in Fig. 18(c), a space S is formed between one cover sheet 40 and the attachment surface, and a space S is formed between the other cover sheet 40 and one cover sheet 40. These spaces S are formed in two layers in the thickness direction of the packaging body 1e. A packaging body 1e shown in Fig. 18(d) has two cover sheets 40 of different sizes, with the smaller cover sheet 40 overlapping the larger cover sheet 40. In the packaging body 1e shown in Fig. 18(d), a space S is formed between the larger cover sheet 40 and the attachment surface, and a space S is formed between the smaller cover sheet 40 and the larger cover sheet 40. These spaces S are formed in two layers in the thickness direction of the packaging body 1e. When two or more cover sheets are provided in this manner, the arrangement of the non-adhesive-coated portions 43 provided on each cover sheet may be different. For example, one cover sheet 40 may have a non-adhesive-coated portion 43 formed on the peripheral edge of one side that is aligned with the first direction X, and the other cover sheet 40 may have a non-adhesive-coated portion 43 formed on the peripheral edge of one side that is aligned with the second direction Y.
