Description

  The present invention relates to a gusset bag and a detergent product, and in particular, includes a pair of front and rear front portions and a pair of left and right side folds that can be folded inside the front portions, and opens an upper end outlet in a self-standing state. The present invention also relates to a gusset bag in which the contents can be taken out, and a detergent product in which a granular detergent is contained in the gusset bag.

  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.

  In addition, such a gusset bag prevents, for example, the stored items from the upper end opening from being inadvertently exposed and allows the stored items to be taken out again, for example, at the front portion near the opening. A folding line is provided so that the upper end portion is folded back, or a cover piece is connected to the upper end of one front part and a locking string is provided on the cover piece, and this locking string is opened on the other front part. A device has been devised in which the upper end opening is closed by being wound around a winding locking piece provided near the portion.

  Furthermore, in such a gusset bag, in order to more smoothly and reliably open and close the upper end opening after accommodating the contents, in the vicinity of the bag mouth of the bag made of craft paper coated with waterproof coating, Horizontally along one or both edges of the mouth of a bag body made of a metal member (aluminum) for closing (for example, see Patent Document 1) or a bag body made of paper, vinyl, etc. A device provided with a sealing metal fitting to which a wire or a ribbon-like metal core material is attached in the direction and further along the side edge is disclosed (for example, see Patent Document 2).

  On the other hand, the use of the gusset bag has been expanded by devising the sheet material constituting the gusset bag, the form of the gusset bag, and the like. And, for example, in the case of a gusset bag that is commercialized in a state where a powdery or granular detergent or the like is stored as a stored item, in order to make it easier to take out the stored item, particularly when the gusset bag is used in a self-supporting state. When the upper end outlet is opened, it is desirable to keep the upper end outlet largely open against the V-shaped folds of the side folds.

  However, according to the gusset bags of Patent Documents 1 and 2, the paper is used to form a rectangular upper end opening by expanding the folded portion of the side folded portion from the flat folded state, and then to accommodate the contents. Or since it is a simple bag made from plastic, when these are made into a product as a bag container that can be used by repeatedly taking out a stored item such as a detergent, various problems arise. That is, the gusset bag described in Patent Document 1 is a small paper bag made of kraft paper provided in an automobile to accommodate, for example, garbage and vomit, and the metal member (aluminum) piece for closing is simply a bag mouth. However, it does not make it easy to repeatedly take out the stored items while opening and closing the gusset bag. Further, the gusset bag described in Patent Document 2 is a bag made of paper, vinyl, etc., and the sealing metal fitting attached to the mouth portion of the bag body is closed after the product is put in and the mouth portion is closed. It is intended to close the mouth without attaching a sealing paper or the like by simply bending the mouthpiece, and does not make it easy to repeatedly take out the contained items while opening and closing the gusset bag.

  Furthermore, according to the garbage bags and waste disposal bags of Patent Documents 3 and 4, a thin metal strip or wire provided along the bag edge, or a wire such as a wire to which the four corners of the bag are fastened. The support post portion holds the opening shape of the bag while putting garbage or waste into the bag, but does not open the bag again after folding the wire or the like to seal the bag. Therefore, it is not easy to repeatedly take out the stored items while opening and closing the bag.

  Furthermore, in the case of a gusset bag that can be used by repeatedly taking out stored items such as detergents, especially when the gusset bag is used in a self-supporting state, the upper portion of the stored items decreases as the use amount decreases. When the portion in which the accommodated item is not accommodated is increased, the length from the take-out port to the accommodated item is increased, making it difficult to remove the accommodated item.

  The present invention is commercialized in a state in which the contents are enclosed, for example, in a gusset bag in which the sealing portion at the upper end is cut out to form a take-out port, and the contents can be repeatedly taken out and used in a self-standing state. It is possible to keep the opening shape of the upper end outlet when taking out the contents large, making it easy to take out the contents, and easily holding out the contents even when the contents are reduced An object of the present invention is to provide a gusset bag that can be produced and a detergent product in which a granular detergent is contained in the gusset bag.

  The present invention includes 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 allows the contents to be taken out while opening the upper end outlet in a self-standing state. A gusset bag, wherein the side-folded portion is provided with a plurality of plastically deformable lateral linear members arranged below the upper portion of the side-folded portion and extending so as to intersect with the folding center line at intervals. By providing an attached gusset bag, the above object is achieved.

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

  Here, the plastically deformable lateral 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 maintained, and when, for example, a side fold portion folded into a V shape is expanded In addition, it has a shape-retaining rigidity at the time of plastic deformation that can resist the restoring force of the sheet material of the side-folded portion into the V shape and can stably hold the expanded state of the side-folded portion. Further, the lateral linear member includes, for example, an elongated strip-like member having a certain width in addition to a linear member such as a wire. Further, the lateral linear members include those that are continuous as one linear member and those that are intermittently continuous.

  Furthermore, the transverse linear member intersects the folding center line perpendicularly if it is in a form that can stably hold the expanded state due to its shape retention rigidity when the folded side folded portion is expanded. However, it is not always necessary to extend, and in addition to the case where it extends so as to obliquely intersect the folding center line, for example, it extends in a V shape on both sides of the folding center line, The case of extending in a curved shape such as an arc is also included.

  According to the present invention, a gusset bag or a gusset bag that is commercialized in a state in which the contents are enclosed, for example, cuts off the sealing portion at the upper end to form a takeout port, and allows the contents to be repeatedly taken out and used. In detergent products containing powdery detergent, it is possible to keep the opening shape of the upper outlet opening when taking out the contents in a self-supporting state, making it easier to remove the contents and reducing the contents. Even in this case, the ease of taking out the stored items can be easily maintained.

  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 powdery detergent as a container, and as shown in FIGS. 2 (a) and 2 (b), the upper end is taken out. From the state in which the mouth 11 is sealed, the user cuts off the sealed portion along the cut line 20 to form the upper end outlet 11, and repeats the detergent 16 from the upper end outlet 11. In addition to making it possible to take out and use the detergent 16, each time the necessary amount of the detergent 16 is taken out, it is possible to block the take-out opening 13 in a smooth and stable state so that the stored detergent 16 can be effectively stored. To do. That is, the gusset bag 10 according to the present embodiment constitutes a detergent product that accommodates the powdery detergent 16 so that it can be repeatedly taken out.

  And the gusset bag 10 of this embodiment is provided with a pair of front and rear front portions 14 and a pair of left and right side fold portions 15 that can be folded in a V shape inside these front portions 14 and is in a self-standing state. A detergent bag container that allows the stored detergent 16 to be taken out while opening the upper end outlet 11, and is disposed on the side folding portion 15 downward from the upper portion thereof and intersects with the folding center line 25. Thus, the plastically deformable transverse linear member 26 is attached in a plurality of stages (three stages) at intervals.

  Further, according to the present embodiment, the cutting guide line 21 for cutting the bag in the middle of the height direction is provided in the space between the three-stage horizontal linear members 26.

  Furthermore, according to the present embodiment, the longitudinal linear members 18 that can be plastically deformed extend from the take-out port 13 to the trunk 12 along the upright sides 17 where the front portion 14 and the side folded portion 15 are connected. It is attached.

  According to this embodiment, the gusset bag 10 is formed into a rectangular shape by subjecting one or a plurality of sheet materials 22 cut into a predetermined shape designed in advance to various known folding and joining processes. Surrounding the periphery by a bottom portion 19 having a shape, a pair of front and rear front portions 14 and a pair of left and right side fold portions 15 erected from each side portion of the bottom portion 19, a main body portion of a bag container for containing a detergent is formed. The gusset bag container is formed as a gusset bag container including a trunk portion 12 and a continuous upper portion of the trunk portion 12 and a take-out port portion 13 that is folded back when the gusset bag 10 is closed. Further, the gusset bag 10 has a pair of left and right side folds 15 formed in a V-shape after a predetermined amount of a powdery detergent 16 as a container is introduced from the upper end outlet 11 (see FIG. 2B). The upper outlet port 11 is sealed and sealed, for example, while being folded inwardly, so that the introduced detergent 16 is sealed inside (see FIG. 2 (a)), and the detergent 16 is not accommodated. For example, the product is commercialized as a detergent product in a state where a certain outlet 13 is double-folded (see FIG. 1).

  Moreover, according to this embodiment, the multilayer material containing an aluminum foil layer is used as the sheet material 22 which comprises the gusset bag 10, Preferably, as shown in FIG. A multilayer sheet having a five-layer structure in which the 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, is a sealant layer can be used. 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 the folding operation when resealing (reseal), and it is difficult for wrinkles or the like to occur in the bag, and the appearance of the gusset bag 10. Can be held well.

  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. A hem seal 23 which is a folded seal portion is formed by folding back and bonding with a hem seal width of, for example, about 2 to 30 mm, and is joined and integrated into a hollow cylindrical shape having a rectangular cross section. Moreover, by this, when the opening 11 at the upper end of the gusset bag 10 is opened, it has a rectangular shape having the same size as the bottom portion 19. The pair of front and rear front portions 14 and the pair of left and right side folded portions 15 are connected to each other at four vertical edges 17 via hem seals 23, so that the shape retaining property of the gusset bag 10 and the outlet 11 can be maintained. It becomes possible to sufficiently exhibit the opening retainability.

  According to the present embodiment, the plastically deformable lateral linear member 26 attached to each side fold 15 is a straight member perpendicularly intersecting the fold center line 25 and is substantially the same as the side fold 15. Each is extended over the entire width and is provided at one upper end portion adjacent to the upper end outlet 11 which is the upper portion of the side folding portion 15 and has a distance of, for example, about 20 to 100 mm downward from the upper end portion. In this way, a total of three stages are attached.

  Further, according to the present embodiment, each of the lateral linear members 26 has the longitudinal linear members 18 provided at both ends thereof along the standing edges 17 where the front portion 14 and the side surface folding portion 15 are connected. A three-stage U-shape is formed together with these longitudinal linear members 18 continuously.

  Here, according to the present embodiment, the plastically deformable transverse linear member 26 and longitudinal linear member 18 have a thickness of, for example, 0.1 to 5.0 mm, preferably 0.3 to 1.0 mm. The metal wire is attached to the outer surface of the side sheet 15 so as to be covered with, for example, an adhesive tape. Further, according to the present embodiment, the longitudinal linear member 18 is provided intermittently and continuously in a state of being previously cut at a portion where the cutting guide lines 21 intersect.

  In addition, according to this embodiment, as the horizontal linear member 26 or the vertical linear member 18, for example, a metal wire having a thickness of 0.1 to 5.0 mm, preferably 0.3 to 1.0 mm. Those covered with a coating resin can be preferably used. Here, as the coating resin, for example, polyolefin resin, vinyl chloride, or the like can be used. By using the wire in which the wire is covered with the covering resin as the transverse linear member 26 or the longitudinal linear member 18, the thickness (diameter) of the wire is substantially increased, and these linear members 26, 18. The bending strength when the linear members 26 and 18 are bent can be increased, and the repeated bending durability can be effectively improved. Further, the coating resin preferably covers a metal wire with a wide flat shape, which makes it possible to improve the handling properties of the lateral linear member 26 and the longitudinal linear member 18.

  Moreover, according to this embodiment, the cutting guide line 21 provided in the space | interval part of the 3 steps | paragraph of horizontal direction linear member 26 is comprised, for example by the cutting tape, and the said cutting guide line 21 in the side surface folding part 15 is 2 A pair of front and rear front portions 14 and a pair of left and right side surfaces are arranged over the entire circumference of the gusset bag 10 so as to pass in parallel through the upper portion adjacent to the step and third row linear members 26. The gusset bag 10 can be cut in the middle of the bag height direction in two stages in succession to the folding portion 15.

  Here, the cutting tape constituting the cutting guide line 21 itself has a cutting function by, for example, peeling off the tape. As a cutting tape, for example, as disclosed in JP-A No. 2000-142726, the bag body is circulated from one end on the heat-welding side of the film constituting the bag body, and fixed to the other end. The opened tape can be used.

  According to the present embodiment, the cutting guide line 21 is a linear portion that guides the gusset bag so that a cut that crosses the gusset bag in the lateral direction can be easily formed, like the cutting tape described above. In addition to the one having a cutting function itself, a cutting portion by a cutting member such as a scissors may be simply guided or clearly indicated by a line segment or the like. Moreover, the cutting guide line 21 should just be provided in the at least one front part 14 of the gusset bag 10 in the case of what guides or shows clearly the cutting position by cutting members, such as a scissors, for example.

  Further, according to the present embodiment, as described above, the longitudinal linear member 18 is provided intermittently and continuously in a state of being previously cut at a portion where the cutting guide lines 21 intersect, Although the structure which can be cut | disconnected along the cutting guide line 21 is provided, as another method of enabling the longitudinal direction linear member 18 to be cut | disconnected along the cutting guide line 21, as a longitudinal direction linear member, a hook etc. It is also possible to use a material that can be cut by the cutting member, or a method of forming a portion where the cutting guide line of the longitudinal linear member intersects with a material that can be cut by the cutting member.

  And the gusset bag 10 of this embodiment is commercialized as a detergent product in the state which enclosed the powdery detergent 16 as mentioned above, and a user cuts off the sealing part of an upper end and opens the upper end extraction port 11 The detergent 16 is repeatedly taken out and used while repeatedly forming and closing the upper outlet port 11 by opening the upper outlet port 11 and turning back the outlet port part 13 (see FIG. 4). According to the bag 10, it is possible to keep the opening shape of the upper end outlet 11 when the detergent 16 is taken out in a self-supporting state so that the detergent 16 can be easily taken out, and even if the detergent 16 is reduced, the detergent The ease of taking out 16 can be easily maintained.

  In other words, according to the present embodiment, the side folding part 15 is disposed in a downward direction from the upper part close to the upper end outlet 11 and extends in a plastically deformable lateral line extending across the folding center line 25. Since the member 26 is attached in three steps at intervals, when the upper end outlet 11 is opened, the transverse linear member 26 is restored to a linear shape and supported so that it is folded inward. It is possible to easily hold the large opening shape of the upper end outlet 11 that is expanded in a rectangular shape in a state where the side folding portion 15 is extended, and thereby it is possible to improve the ease of taking out the stored detergent 16. become.

  Moreover, according to this embodiment, since the horizontal direction linear member 26 is provided in multiple steps (three steps) at intervals in the height direction of the gusset bag 10, the internal detergent 16 is reduced by use. As a result, the upper portion of the gusset bag 10 may be moved in two steps as required even if the length from the upper end outlet 11 to the detergent becomes longer due to the larger portion where the upper detergent 16 is not accommodated. By cutting sequentially through the cutting guide line 21 at the upper part adjacent to the eye or the third-stage horizontal linear member 26, the excess bag in which the detergent 16 is not accommodated is separated and the second stage Alternatively, the ease of taking out the detergent 16 can be continuously improved by the function of maintaining the large opening shape of the upper end outlet 11 by the horizontal linear member 26 in the third stage.

  Furthermore, according to the present embodiment, the longitudinal linear members 18 that can be plastically deformed are attached from the take-out port 13 to the trunk 12 along the upright side 17 where the front portion 14 and the side folded portion 15 are connected. Therefore, when the upper end outlet 11 is opened and opened into a rectangular shape, the longitudinal linear members 18 standing at the four standing edges 17 function as pillars at the four corners, and the gusset bag In the state in which 10 is self-supporting, it is possible to hold the state in which the upper end outlet 11 is widely opened more effectively. Further, the longitudinal linear member 18 can be easily bent and deformed by the force of a finger of the hand, and has a plastic deformation property to such an extent that the shape after the bending can be easily maintained. When the gusset bag 10 is closed by folding back, when the plastic deformation is such that it effectively resists the folding restoring force by the sheet material 22 of the take-out port 13 and can stably hold the folded state of the take-out port 13 Therefore, while the side folding portion 15 is folded inward, the upper ends of the pair of front surface portions 14 in the upper end outlet 11 are overlapped to close the upper end outlet 11, and the longitudinal linear member 18 is closed. At the same time, the sheet material 22 of the take-out port 13 is simply folded back along the turn-up portion 24, and as shown in FIG. It is possible to easily and reliably placed.

  The present invention can be variously modified without being limited to the above embodiments. For example, the sheet material constituting the gusset bag is not necessarily a multilayer sheet having the above-described configuration including an 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 such as polyester or polyethylene can be used. In addition, the container to be stored is not necessarily a powdery detergent, and is used as a bag container for storing various other containers such as liquid containers such as shampoo and rinse, and solid containers such as confectionery. You can also

  Further, it is not always necessary to provide the cutting guide lines at the interval portions of the plurality of lateral linear members, and the bag may be cut at an arbitrary position of the interval portions.

  Further, it is not always necessary to provide the longitudinal linear member along the vertical side where the front portion and the side folded portion are connected. For example, as shown in FIGS. 5A to 5C, the lateral linear member 26 is provided. Can be provided so as to intersect with the folding center line 25 at an angle to the extent that it does not impair the function of maintaining the opening state of the upper end outlet 11, and extends in a V shape on both sides of the folding center line.
