Description

  The present invention relates to a gusset bag and a detergent product, and in particular, a gusset bag including a gusset bag body including a pair of front and rear front portions and a pair of left and right side folding portions that can be folded inside the front portions, and the gusset bag. The present invention relates to a detergent product containing a powdery detergent.

  A gusset bag is a bag comprising a pair of front and rear front portions formed from one or a plurality of sheet materials, and a pair of left and right side folding portions that can be folded into a V shape inside these front portions. Then, from the state where the side folding portion is folded and flatly folded, the folding portion in the vicinity of the opening is opened to form a rectangular upper end opening so that various items can be accommodated inside the upper end opening. It has become.

Such a gusset bag has various contrivances for making it possible to more smoothly and reliably close the upper end opening after containing the contents. For example, the mouth of the bag body made of paper, vinyl, etc. A gusset bag is disclosed in which a sealing metal fitting with a metal core material in the form of a wire or a ribbon is attached laterally along one or both edges of the portion, and further along the side edge (for example, Patent Documents). 1). In addition, as a bag in which the closed bag mouth is reopened and the stored contents can be taken out, a flammable wire or band is fixed to the neck of the bag in an inverted V shape to form a fastening tool. An article bag is disclosed in which a bag mouth can be easily sealed with an accessory (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 49-12112 Japanese Utility Model Publication No. 53-16507

  However, according to the gusset bag and the article bag described in each of the above-mentioned patent documents, the reverse V-shape by a metal fitting or a metal fitting for closing the upper end opening of the bag smoothly and reliably. All mold clamping tools need to be assembled and installed in advance in a gusset bag or article bag, and the work process for attaching them becomes complicated, making it difficult to manufacture the bag and costly Will increase.

  In addition, the use of the gusset bag has been expanded by devising the sheet material constituting the gusset bag, the form of the gusset bag, etc., for example, as a bag container for containing a powdery or granular detergent, etc. It is commercialized in a state in which the contents are enclosed by sealing, and the user cuts off the sealing portion at the upper end to form the upper end opening, and the detergent etc. in a state where it is self-supported while opening and closing the formed upper end opening. For gusseted bags that can be repeatedly taken out and used, the contents are enclosed by simplifying the process for attaching a reseal member for resealing the top opening so that it can be opened and closed after the sealing portion has been cut off. There is a demand for efficient commercialization of the gusseted bag in the finished state.

  On the other hand, according to conventional gusset bags and article bags in which sealing fittings and fastening tools are integrated, it takes time to remove these fittings from the main body of the bag. It tends to be neglected to dispose of the main body part and sealing fittings and fastening tools.

  The present invention can easily attach a reseal member for closing the take-out opening so as to be openable and closable without requiring a complicated process, and can easily separate and discard the reseal member and the bag body. The purpose is to provide gusset bags.

  The present invention includes a gusset bag body including a pair of front and rear front portions and a pair of left and right side foldable portions that can be folded inside the front portions, and at least of four surfaces of the front portion or the side fold portions. By providing a gusset bag comprising a resealable insertion sheet to which a longitudinal linear member that is plastically deformable is a sheet member that is inserted and arranged in the gusset bag main body along one inner side surface, The above objective has been achieved.

  Moreover, this invention achieves the said objective by providing the detergent product formed by accommodating a granular detergent in the said gusset bag.

  In the above description, the plastically deformable longitudinal linear member is made of, for example, a metal wire, a plate, a narrow plate, a mesh, a ribbon, a shape memory alloy, a shape memory resin, or the like. It is a linear member that can be easily bent and deformed, and has plastic deformability to such an extent that the shape after bending can be easily held, and when the gusset bag is closed by folding the take-out opening, It has shape retention rigidity at the time of plastic deformation that resists the folding restoring force of the sheet material at the mouth and can stably hold the folded state of the take-out mouth. In addition to the linear member such as a wire, the linear member includes, for example, an elongated strip-shaped member having a certain width. Furthermore, a linear member includes what is intermittently continuous in addition to what is continuous as a single linear member.

  Moreover, when using metal linear members, such as a wire, as a linear member which can be plastically deformed, it is preferable to use these in the state covered with coating resin. By covering the linear member with a coating resin, the thickness of the linear member can be substantially increased to improve the bending strength and to increase the bending radius when bent by plastic deformation. Thus, it is possible to effectively improve the repeated bending durability for avoiding the breakage of the linear member. Further, even when these linear members are repeatedly bent and broken, it is possible to further improve safety by covering the cut surface with the coating resin.

  Further, the longitudinal linear member does not necessarily have to be linearly extended and disposed in the vertical longitudinal direction when the resealable insertion sheet is inserted and disposed in the gusset bag body. As long as it is continuously arranged in the vertical region extending from the take-out port part to the trunk part, it includes those arranged to be inclined and extended and arranged in a curved state. It is.

  According to the gusset bag of the present invention, it is possible to easily attach a reseal member for closing the take-out opening so as to be openable and closable without requiring a complicated process, and to easily separate and discard the reseal member and the bag body. Can be done.

  A gusset bag 10 according to a preferred embodiment of the present invention shown in FIG. 1 is used as a container for containing, for example, a powdered detergent as a container. As shown in FIGS. From the state in which the mouth 11 is sealed, the user cuts off this sealed portion along the cut line 25 to form the upper end outlet 11, and the detergent 30 is repeated from the upper end outlet 11. While taking out a necessary amount of the detergent 30 while taking it out, it is possible to open and close the take-out opening 13 in a smooth and stable state, and to effectively preserve the stored detergent 30 each time. It is possible to use. That is, the gusset bag 10 according to the present embodiment constitutes a detergent product containing a granular detergent.

  As shown in FIG. 3, the gusset bag 10 of this embodiment includes a pair of front and rear front portions 14 and a pair of left and right side folding portions 15 that can be folded in a V shape inside these front portions 14. And a longitudinal linear member 18 that is plastically deformable and is a sheet member that is inserted into the gusset bag main body 16 along one inner surface of the pair of front and rear front portions 14. It is constituted by the resealable insertion sheet 19.

  Further, according to the present embodiment, the longitudinal linear members 18 are attached along both side edges of the resealable insert sheet 19, and the resealable insert sheet 19 is the inner surface of one front portion 14. When the longitudinal linear members 18 on both side edges are inserted and arranged along the gusset bag main body 16 along the vertical side of the gusset bag main body 16, the vertical side linear members 18 are adjacent to the vertical side 17 where the front surface part 14 and the side surface folding part 15 are connected. 17 are arranged so as to be parallel to each other.

  According to the present embodiment, the gusset bag main body 16 constituting the gusset bag 10 is formed by applying various known folding processes and joining to one or a plurality of sheet materials 22 cut into a predetermined shape designed in advance. By carrying out the processing, the bottom 21 having a rectangular shape, a pair of front and rear front portions 14 and a pair of left and right side folds 15 erected from each side portion of the bottom 21, and a bag for containing detergent A gusset bag container comprising a body portion 12 constituting a main body portion of the container, and a takeout port portion 13 which is continuously disposed integrally with the upper portion of the body portion 12 and is folded back when the gusset bag 10 is closed. Formed as. The gusset bag main body 16 has a pair of left and right side folded portions 15 formed into a V-shape after a predetermined amount of a powdered detergent 30 as a container has been introduced from the upper end outlet 11 (see FIG. 2B). The upper outlet 11 is sealed and sealed, for example, while being folded inwardly, so that the introduced detergent 30 is sealed inside (see FIG. 2A), and the unaccommodated portion of the detergent 30 The take-out opening 13 is, for example, a product folded in a double-folded state (see FIG. 1).

  Further, according to the present embodiment, a multilayer sheet including an aluminum foil layer is used as the sheet material 22 that forms the gusset bag body 16, and preferably, as shown in FIG. A multilayer sheet having a five-layer structure in which one layer is polyester, the second layer is polyethylene, the third layer is aluminum foil, the fourth layer is polyethylene, and the fifth layer, which is the innermost layer, can be used. In addition, the thickness of the aluminum foil layer in the multilayer sheet is preferably 5 to 50 μm, and more preferably 5 to 20 μm. By using a multilayer sheet including an aluminum foil layer as the sheet material 22, it is possible to facilitate a folding operation when resealing (resealing), and it is difficult for wrinkles or the like to occur in the bag, and the gusset bag 10 It becomes possible to maintain a good appearance.

  Further, the pair of front and rear front portions 14 and the pair of left and right side side folding portions 15 are formed with the innermost sealant layer of the sheet material 22 at the vertical sides 17 at the four vertical sides 17 of the body portion 12 and the outlet port portion 13. For example, it is joined and integrated into a hollow cylindrical shape having a substantially rectangular cross section through a hem seal 23 which is a folded seal portion by folding and joining with a hem seal width of, for example, about 2 to 30 mm. Further, by this, the take-out port 11 at the upper end of the gusset bag main body 16 has a rectangular shape having substantially the same size as that of the bottom portion 21 when opened. The pair of front and rear front portions 14 and the pair of left and right side side folded portions 15 are joined to each other by hem seals 23 at the four standing edges 17 so that the shape retention of the gusset bag body 16 and the opening of the take-out port 11 can be achieved. It becomes possible to fully exhibit the retainability.

  As shown in FIG. 3, the resealable insertion sheet 19 that constitutes the gusset bag 10 of the present embodiment together with the gusset bag body 16 has a rectangular shape substantially the same as the shape of the front portion 14 of the gusset bag body 16. The sheet member 20 includes a pair of longitudinal linear members 18 attached along both side edges of the insertion sheet member 20.

  According to the present embodiment, the insertion sheet member 20 has a flexibility that can be easily bent in response to the curved deformation of the front portion 14 of the gusset bag body 16, and has a smooth continuous surface. For example, a transparent plastic sheet material is used as a material having a shape retaining rigidity that can be easily held, and is easily inserted and arranged along the inner surface of the front portion 14 of the gusset bag body 16. Furthermore, it has a rectangular shape slightly smaller than the rectangular shape of the inner surface. By forming the insertion sheet member 20 in substantially the same shape slightly smaller than the front part 14, the resealing insertion sheet 19 is attached along the inner surface of the front part 14 in a stable state with little deviation. It becomes possible to keep. The insertion sheet member 20 can also be formed using a metal sheet such as an aluminum foil, a paper sheet, or the like in addition to a plastic sheet material. Moreover, as these sheet materials, various materials made by using methods such as incorporation, molding, and knitting can be used.

  Further, according to the present embodiment, the longitudinal linear member 18 is made of a metal wire having a thickness of 0.1 to 5.0 mm, preferably 0.3 to 1.0 mm, for example, an adhesive tape or the like. Are attached along both side edges of the insertion sheet member 20. These longitudinal linear members 18 are at least a length extending from the take-out port portion 13 of the gusset bag body 16 to the trunk portion 12 when the resealable insertion sheet 19 is inserted and arranged in the gusset bag body 16, for example, It is attached to the upper half part of the insertion sheet member 20.

  Here, the take-out port portion 13 of the gusset bag main body 16 is, for example, the folded portion 24 when folded at an appropriate position in an area extending from the upper end portion to the lower half portion in order to close the gusset bag main body 16. The body portion 12 of the gusset bag main body 16 is a portion that is positioned below the folded portion 24 and that constitutes a main body portion that accommodates the detergent 30. That is, according to the first embodiment, the position of the folded portion 24 that is folded when the gusset bag main body 16 is closed moves up and down as the detergent 30 stored in the gusset bag main body 16 decreases. Since the position of the folded portion 24 is arbitrarily selected within a predetermined area without being specified in advance, the folded portion where the gusset bag main body 16 is actually folded when closed. An upper part sandwiching 24 is defined as an outlet 13 and a lower part is defined as a body 12. Therefore, “attached with a length extending from the take-out port 13 to the body 12” means that at least the portion of the gusset bag body 16 in the vertical direction of the gusset bag body 16 where the folded-back portion 24 is expected to be located at the time of closing. This means that the longitudinal linear member 18 is attached.

  Further, according to the first embodiment, as shown in FIG. 5A, it is preferable that the longitudinal linear member 18 made of a metal wire is covered with the coating resin 27. Here, as the coating resin, for example, polyolefin-based resin, vinyl chloride, polyester-based resin, polyamide-based resin, and the like can be used. For example, the periphery of the longitudinal linear member 18 with a thickness of 0.05 to 5.0 mm It is preferable to cover. Moreover, it is more preferable to set it as 0.05-3.0 mm from the external appearance of a bag. By covering the periphery of the longitudinal linear member 18 with the coating resin 27, the thickness (diameter) of the longitudinal linear member 18 is substantially increased, and the bending strength of the longitudinal linear member 18 is improved. Is possible. Further, as shown in FIGS. 6A and 6B, the inner peripheral bending radius R when the longitudinal linear member 18 is folded is set to the case where only the longitudinal linear member 18 is used (see (b), for example, R <1 mm) (see (a), for example, R ≧ 1.5 mm, preferably R ≧ 2.5 mm), thereby avoiding breakage of the longitudinal linear member 18 Therefore, it is possible to effectively improve the repeated bending durability. Further, even when the longitudinal linear member 18 is repeatedly bent and broken due to deterioration of the bent portion, it is possible to further improve the safety by covering the cut end with the coating resin 27.

  Here, by covering the periphery of the longitudinal linear member 18 with the coating resin 27, the workability of the longitudinal linear member 18 and the workability of attaching to the gusset bag 10 can be further improved. Further, by covering the periphery of the longitudinal linear member 18 with the covering resin 27 with a wide flat shape as shown in FIG. 5B, the handling property of the longitudinal linear member 18 is further improved and the bonding is performed. By increasing the area, for example, it is possible to effectively improve the bonding strength by heat sealing or the like.

  And according to this embodiment, when manufacturing the gusset bag 10 which accommodated the detergent 30, the gusset bag main body 16 and the insertion sheet 19 for resealing are formed as a separate member, for example, a gusset bag main body 16 Prior to the introduction of the detergent 30, the resealable insertion sheet 19 is inserted and arranged from the upper end outlet 11 along the one front portion 14 of the gusset bag main body 16. After that, the detergent 30 is put into the gusset bag main body 16 and the upper outlet port 11 is sealed and sealed, for example, and the product is commercialized as a detergent product with the outlet port 13 folded back, for example. (See FIG. 1).

  Moreover, when using the detergent 30 accommodated in the gusset bag 10, the user cuts off the sealing portion at the upper end along the cut line 25 to form the upper end outlet 11, and repeatedly takes out the detergent 30. However, according to the gusset bag 10 of the first embodiment, the detergent 30 is effectively stored while closing the take-out opening 13 so that it can be opened and closed easily and securely. Can be easily removed repeatedly.

  That is, according to the present embodiment, the resealable insertion sheet 19 as a reseal member is inserted and arranged in the gusset bag body 16, and the pair of longitudinal linear members 18 are removed from the take-out port 13 of the gusset bag body 16. Each is attached along the upright side 17 with a length straddling the body portion 12. These longitudinal linear members 18 can be easily bent and deformed by the force of the fingers of the hand, and have plastic deformability to such an extent that the shape after the bending can be easily held, and the take-out port portion 13 is formed. When the gusset bag 10 is folded and closed, it effectively resists the folding restoring force caused by the sheet material 22 of the take-out port 13 and can be stably held in the folded state of the take-out port 13 at the time of plastic deformation. Has shape retention rigidity. Therefore, as shown in FIG. 7, the upper side outlet 14 is overlapped with the upper ends of the pair of front surface portions 14 while the side folding portion 15 is folded inward, and the upper end outlet 11 is closed and the linear linear member 18 is taken out. It is possible to easily and reliably close the take-out port portion 13 of the gusset bag 10 by a simple operation of only folding the sheet material 22 of the mouth portion 13 downward along the folding portion 24.

  The gusset bag 10 can be closed by folding the take-out port 13 by one-time folding along the folding part 24 (see FIG. 7). By turning back more than once (see FIG. 1), the gusset bag 10 can be more reliably closed. Further, for example, by drawing a folding guide line in advance on the surface of the front portion 14, the take-out port 13 can be folded along the folding guide line, and further, the stored detergent 30 can be reduced. Accordingly, the take-out port portion 13 can be folded back while appropriately shifting the folding portion 24 downward.

  Furthermore, when the amount of the detergent 30 is reduced, the upper part of the bag 10 is cut off to a place where the detergent 30 can be easily taken out, and then the lower part of the resealable insertion sheet 19 is cut at an appropriate position to remove the detergent 30. The height of the bag can be appropriately modified so that it can be easily taken out.

  When the stored detergent 30 is used again, the upper end outlet 11 is opened while plastically deforming the folded longitudinal linear member 18 so as to restore the linear shape, and such a longitudinal direction is used. The detergent 30 is used while repeatedly opening the upper end outlet 11 and closing the outlet 13 with the linear member 18 as a core.

  Further, according to the present embodiment, the resealing insertion sheet 19 as a resealing member is formed as a separate member from the gusset bag body 16 and is attached by being inserted and disposed along the front portion 14 of the gusset bag body 16. Therefore, when the stored detergent 30 is lost and the gusset bag 10 is discarded, the resealable insertion sheet 19 can be separated from the gusset bag body 16 only by taking it out from the gusset bag body 16. The operation of removing the longitudinal linear member 18 from the resealable insertion sheet 19 can be easily performed, and the separation and disposal with the gusset bag main body 16 can be performed smoothly.

  Therefore, according to the gusset bag 10 of the present embodiment, the reseal member for closing the take-out port portion 13 so as to be openable / closable is complicated by simply inserting the resealing insertion sheet 19 into the gusset bag body 16. It is possible to easily attach without requiring an additional process, and to easily separate and discard the reseal member and the bag body.

  Note that the present invention is not limited to the above embodiment, and various modifications can be made. For example, the gusset bag of the present invention is not limited to a bag container that allows a stored item to be taken out while opening the upper end outlet in a self-standing state, and inserts a resealable insertion sheet into the gusset bag body. It can also be employed as a gusseted bag that simply accommodates the contents without being self-supporting. Further, the sheet material constituting the gusset bag is not necessarily the multilayer sheet having the above-described configuration including the aluminum foil layer, and may be a sheet material not including the aluminum foil layer or a single layer sheet material. For example, a sheet material made of polyolefin resin, vinyl chloride, polyester resin, polyamide resin, or the like can be used in a single layer or multiple layers. Furthermore, the contents stored in the gusset bag in a self-supported state do not necessarily need to be a powdery detergent, but include various other types such as liquid contents such as shampoo and rinse, solid contents such as confectionery, etc. It can also be used as a bag container for storing the contents.

  In addition, the resealable insertion sheet is not necessarily inserted and arranged in advance in the gusset bag main body, for example, manufactured and sold in combination with the gusset bag main body as a separate member. If necessary, the user can insert and place it inside the gusset bag body. Also, for example, remove the attached measuring spoon from the portion of the re-sealable insert sheet where the longitudinal linear members are not attached. It can also be attached as possible. Further, the resealable insertion sheet does not necessarily have the same size and shape as the front and side folded portions of the gusset bag main body, and is used as a bag container for containing, for example, a powdery detergent. In this case, it can be formed in a shape corresponding to the shape of the front portion or the side folded portion in the region above the portion in which the detergent is accommodated, so that it can be easily inserted and placed later. Furthermore, the longitudinal linear member can be attached with a tack seal or an adhesive, or welded and attached to the insertion sheet member of the resealable insertion sheet, and the longitudinal linear member is made of metal. It is not always necessary to be a wire.

  And according to the present invention, the resealable insertion sheet can be inserted and arranged not only along the inner surface of the front portion of the gusset bag body, but also along the inner surface of the side fold portion. It can also be inserted and arranged simultaneously along two or more inner side surfaces. Furthermore, it is not always necessary that a pair of the longitudinal linear members 18 be provided along both side edges of the resealable insertion sheet 19. For example, as shown in FIG. Only one can be provided in the central portion of the member 20, or three or more can be provided.

  Furthermore, for example, as shown in FIGS. 8B and 8C, the upper ends of the pair of longitudinal linear members 18 attached to both side edges of the resealable insertion sheet 19 are provided with a pair of longitudinal members. A plastically deformable lateral linear member 26 that forms a U-shape together with the directional linear member 18 can be attached to the resealable insertion sheet 19. By providing the pair of longitudinal linear members 18 together with the lateral linear members 26 so as to form a U-shape, the resealable insertion sheet 19 is particularly provided on the inner side surface of the side folding portion 15 of the gusset bag body 16. When the upper end take-out port 11 is opened, the upper end portion of the side folded portion 15 that has been folded inward is supported by restoring and supporting the linear member 26 in a straight line. In the extended state, the shape of the upper end outlet 11 that is expanded in a rectangular shape can be easily held, and thereby the ease of taking out the stored detergent 30 can be further improved.

  Here, the transverse linear member 26 that forms a U-shape together with the pair of longitudinal linear members 18 is provided continuously with the upper ends of the longitudinal linear members 18 (( b)), provided at an upper end portion including a region slightly shifted up and down between the upper ends of the pair of longitudinal linear members 18 and spaced from the upper ends of the pair of longitudinal linear members 18; For example, a U-shape may be formed by three linear portions spaced apart from each other (see (c)). Similarly to the longitudinal linear member 18, the lateral linear member 26 can be used by covering the periphery thereof with a coating resin 27.

  Furthermore, as shown in FIGS. 8D to 8G, for example, the vertical linear member 18 is provided over substantially the entire vertical length of the resealable insertion sheet 19 (see (d)), It can be provided intermittently without being continuous as a single linear member (see (e))), or can be provided obliquely (see (f))), or three or four or more can be arranged in parallel. (See (f)).
