The bag positioned one below the bag inside the valley formed by the first folded piece and the second folded piece of the bag laminated on the uppermost part of the laminated body. Inside the valley formed by the first and second folds of each of the bags, except for the bags stacked on the top and bottom of the laminate, The first folded piece of the bag located one level below the bag and the second folded piece of the bag located one level above the bag are arranged and laminated at the bottom of the laminate. The second folded piece of the bag positioned one above the bag can be arranged inside the valley formed by the first folded piece and the second folded piece of the bag.

In addition, in the bag product according to the second aspect of the present invention, the bag is placed in at least one of the vicinity of the upper surface of the laminate or the vicinity of the side surface including the third side closer to the symbol of the laminate. A first package may be provided which has a perforation forming a first outlet for taking out and which encloses the laminate in a state in which the symbol can be visually recognized from the outside.

According to the above configuration, for example, the symbol can instruct the user to use the bag with the symbol attached (the bag stacked at the top of the stack). According to this instruction, when the user first takes out the bag with the symbol from the new layered product contained in the package, the frictional force causes a portion of the bag immediately below to pop out from the take-out port. state. In other words, by taking out the bag with the symbol first, the second and subsequent bags can be taken out only by pulling the part protruding from the take-out opening. In addition, since the opening (first side) of the bag is included in the portion protruding from the take-out opening, the opening of the bag can be removed by rubbing the area around the opening of the bag with a finger before taking out the bag by pulling it from the laminate. can open the mouth of In this way, the bag product can be taken out one by one and the mouth of the bag can be opened, and these operations can be performed with one hand. Furthermore, the symbol can be used as a mark for picking out one laminate from a group of successively discharged laminates when laminates are continuously manufactured using an apparatus.

[Bag product 1]

A bag product 1 according to one embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG.

The bag product 1 shown in FIG. 2), and a case 13 (corresponding to an example of the "third package" in the scope of claims, see FIG. 1). Each member is described below.
[Laminate 11]

The laminate 11 is a member formed by laminating a plurality of bags 111 .
<Bag 111>

As shown in FIG. 4, the bag 111 is a rectangular member having a bag mouth 111a on one short side (hereinafter, the side on which the bag mouth The side opposite to the side is called "second side 111c", and the two sides adjacent to the first side and the second side are called "third side 111d").

Also, the bag 111 is made of a sheet member comprising three layers of a surface layer, a barrier layer and an adsorption layer. The barrier layer has a deodorizing function to prevent odors from leaking out from inside the bag 111 , and the adsorption layer has a deodorizing function to adsorb odor components in the bag 111 . As a result, the bag 111 can be suitably used for disposal of used diapers in childcare and nursing care. Note that the form of the bag 111 is not limited to the one described above, and the size, shape, function, and the like may be changed as appropriate.

As shown in FIG. 3, the laminate 11 is a bag 111 (hereinafter referred to as a first side 111b, a third side 111d and a The folded piece partitioned by the folding line 111e is called "first folding piece 111f", and the folding piece partitioned by the second side 111c, third side 111d and folding line 111e is called "second folding piece 111g". The odd-numbered layers and the even-numbered layers are stacked symmetrically. Inside the valley 111h formed by the first folded piece 111f and the second folded piece 111g of each bag 111, the first folded piece 111f of the bag 111 positioned one below the bag 111 and one of the bags 111 The second folded piece 111g of the upper bag 111 is arranged. Since the uppermost bag 111 does not have the bag 111 positioned one level above, only the first folded piece 111f of the bag 111 positioned one level below is arranged inside the valley portion 111h. Similarly, since the lowermost bag 111 does not have the bag 111 positioned one lower, only the second folded piece 111g of the bag 111 positioned one higher is arranged inside the valley portion 111h. As a result, an appropriate frictional force is generated between adjacent bags 111 .

Moreover, as shown in FIG. 2, the bag 111 stacked on the uppermost part of the stack 11 is attached to the upper surface of the stack 11 of the first folded piece 111f and in the vicinity of one third side 111d. It has a mark 111i (corresponding to an example of a "symbol" in the claims). As a result, for example, by writing an explanation on how to use the bag product 1 with the mark 111i as a mark on the outer bag 12, it is possible to instruct the user how to use the bag product.

With the above configuration, the user can instruct to use the stack 11 from the bag with the symbol (the bag stacked at the top of the stack). According to this instruction, the user first attaches the mark 111i to a new laminate 11 enclosed in a package such as an outer bag 12 (details will be described later) or a case 13 (details will be described later). When the bag 111 that has been placed is taken out, the frictional force causes a part of the bag 111 immediately below to protrude from the take-out port. In other words, by taking out the bag 111 with the mark 111i first, the second and subsequent bags 111 can be taken out only by pulling the part protruding from the take-out opening. In addition, since the portion protruding from the take-out port includes the mouth 111a (first side 111b) of the bag, rub the periphery of the mouth 111a of the bag with a finger before pulling out the bag 111 from the laminate 11. , the mouth 111a of the bag can be opened. In this manner, the stack 11 allows the bags to be taken out one by one and the mouth of the bag to be opened, and these operations can be performed with one hand.

In addition, the mode of the laminate 11 is not limited to the above-described one, and as long as the mode includes the mouth 111a (first side 111b) of the bag 111 that protrudes from the outlet of the bag 111, the method of folding the bag 111 (folding line , the angle of the folding line, etc.), the lamination method, etc., can be changed as appropriate. In addition, the "symbol" in the scope of claims is not limited to the arrow mark 111i, and may be a mark other than an arrow, or an explanation of how to use the bag product 1 (in this case, even if the explanation is not written on the outer bag 12). may be used.), or an illustration or the like that intuitively shows how to use it. In addition, the extent of the instruction to "instruct how to use the bag product" in the scope of claims is not particularly limited, and at least the instruction to use from the bag 111 laminated on the top of the laminate 11 may be given. Just do it.
[Outer bag 12]

The outer bag 12 is a transparent bag made of polyethylene, and as shown in FIG. A side surface including the third side 111d has a perforation 12b forming an outlet 12a (corresponding to an example of a "first outlet" and a "first outlet" in the claims).

That is, the user selects and cuts one of the two perforations 12b according to the form and necessity of a case (for example, a case 13 described later) that houses the laminate 11 and the outer bag 12. , forming the outlet 12a. Specifically, when it is used while being housed in a case 13, which will be described later, the side perforations 12b are cut off. In addition, when used by being housed in a general box tissue case, or when being used without being housed in a case, the perforation 12b on the upper surface side is cut off before use.

The form of the outer bag 12 is not limited to the one described above, and a bag made of polypropylene may be used. Further, for example, a symbol may be attached to the outer bag 12 to indicate how to use the bag product. In this case, the symbol of the bag 111 stacked on top of the stack 11 is unnecessary. Furthermore, it is not always necessary to provide the outer bag 12 and the case 13 (details will be described later).
[Case 13]

The case 13 is a member that houses the laminate 11 and the outer bag 12 enclosing the laminate 11, as shown in FIG. The case 13 has a substantially cylindrical shape, and has a lid portion 13a and an outlet 13b (corresponding to an example of a "third outlet" in the scope of claims) on the upper surface. In addition, the case 13 includes the laminated body 11. The bottom surface of the laminated body 11 corresponds to the side surface of the case 13, and the side surface including the third side 111d closer to the mark 111i of the laminated body 11 is the upper surface of the case 13. It can be rolled up into a cylindrical shape and stored. As a result, when the lid portion 13a is opened, the bag with the mark 111i is arranged substantially in the center of the outlet 13b. It can be taken out by simply pulling the part protruding from the take-out port. Moreover, the laminated body 11 can be stored compactly by the case 13 .

In addition, the form of the outer bag 12 is not limited to the one described above, and it may be in the shape of a rectangular tube. In addition, in the bag product 1, the outer bag 12 and the case 13 do not necessarily have to be provided. 11 and case 13 may be used. For example, (1) and (2) can be sold as refills.
[Manufacturing method of bag product]

A method for manufacturing the bag product 1 according to one embodiment of the present invention will be described below with reference to FIGS. 5 to 7. FIG.

As shown in the flowchart of FIG. 5, the bag product 1 includes a laminate manufacturing process ST101 for making a laminate 11, and a packaging process ST102 for packaging the laminate 11 manufactured in the laminate manufacturing process ST101 with an outer bag 12. , and a housing step ST103 in which the laminate 11 wrapped in the outer bag 12 manufactured in the packaging step ST101 is housed in the case 13 .
<Laminate manufacturing process ST101>

In the laminate manufacturing process ST101, the laminate 11 made up of 100 bags 111 is manufactured using the laminate manufacturing apparatus 2 shown in FIG. The laminated body manufacturing apparatus 2 includes a rewinding section 21, a thermal welding section 22, a printing section 23, and a folding section 24, and manufactures the laminated body 11 from the two original fabric rolls GR1 and GR2.

The raw fabric rolls GR1 and GR2 are formed by forming a sheet member, which is the material of the bag 111, into a long cylindrical shape, and folding the member by providing two folding lines (corresponding to the third side 111d) at positions facing each other on the curved surface of the member. Cylindrical sheet members ES1 and ES2 (having a shape like a two-ply rectangular sheet) are wound up into a roll. As shown in the flow chart of FIG. 7, welding step ST101-1, printing step ST101-2 and stacking step ST101-3 are performed while rewinding the two original rolls GR1 and GR2 onto the cylindrical sheet members ES1 and ES2. Through these processes, the raw fabric roll GR1 becomes the odd-numbered bag 111 (including the bag 111 having the arrow mark 111i) counted from the upper surface side of the laminate 11, and the raw fabric roll GR2 becomes the bag 111 having the arrow mark 111i. The even-numbered bags 111 are counted from the upper surface side.
<<Thermal welding process ST101-1>>

The welding step ST101-1 is a step of heat-welding the cylindrical sheet members ES1 and ES2 using the heat-welding portion 22 at regular intervals. The heat-welding part 22 heat-welds the cylindrical sheet members ES1 and ES2 between the two folding lines of the cylindrical sheet members ES1 and ES2 in a linear shape orthogonal to the extending direction of the cylindrical sheet members ES1 and ES2. , form the bottom of the bag (on the side of the second side 111c). That is, by increasing the heat-sealed interval in the welding step ST101-1, the interval between the first side 111b and the second side 111c of the bag 111 is increased, and the capacity of the bag 111 can be increased. Conversely, if the heat-sealed interval in the welding step ST101-1 is reduced, the interval between the first side 111b and the second side 111c of the bag 111 is reduced, and the capacity of the bag 111 can be reduced.
<<Printing process ST101-2>>

In the printing step ST101-2, the printing unit 23 is used to mark the cylindrical sheet member ES1 unwound from the original fabric roll GR1 attached to the upper side of the laminate manufacturing apparatus 2 with arrow marks 111i at regular intervals. This is the process of printing. The timing of printing by the printing unit 23 is controlled using information from the sensor of the rewinding unit 21, and printing is performed at a pace of once every 50 thermal weldings in the thermal welding step ST101-1.
<<Lamination step ST101-3>>

In the stacking step ST101-3, the folding unit 24 is used to cut the cylindrical sheet members ES1 and ES2 to form the bag 111, and the formed bag 111 is stacked while being folded to manufacture the stack 11. is.

As shown in FIG. 6, the folding section 24 includes cutting rollers 241a and 242a, folding rollers 241b and 242b, and pressing sections 241c and 242c. The cylindrical sheet members ES1 and ES2 are cut by the cutting blades of the cutting rollers 241a and 242a rotating in the directions indicated by the arrows to lengths corresponding to the length of the bag 111 (intervals heat-sealed in the welding step ST101-1). A bag 111 is obtained. Folding line 111e is formed in bag 111 by folding rollers 241b and 242b that rotate in the direction indicated by the arrow while contacting each other. After that, the bag 111 is peeled off from the folding rollers 241b and 242b by the pressing portions 241c and 242c, so that the bag 111 falls by its own weight and is folded along the folding line 111e. A laminate 11 is obtained.
<Packaging step ST102>

In the packaging step ST102, the laminate 11 manufactured in the laminate manufacturing step ST101 is packaged in the outer bag 12. As shown in FIG. In the laminated body manufacturing step ST101, as shown in FIG. 6, the laminated body 11 made up of 100 bags 111 is continuously manufactured. Take it out and pack it in the outer bag 12 .

The method of packaging in the outer bag 12 is not particularly limited, and may be a manual packaging method or an automated or semi-automated packaging method using a device. However, depending on the material of the bag 111, the frictional force is low and the bag is slippery, so there are cases where an automated or semi-automated packaging method using a device is not suitable. In this case, manual packaging methods are preferred. Moreover, the mode of the packaging step ST102 is not limited to the above-described one, and for example, the laminate 11 may be inspected. In this case, since several bags 111 are to be extracted from the laminate 11, it is preferable to manufacture the laminate 11 by increasing the number of bags 111 in advance in the laminate manufacturing step ST101.
<Storage step ST103>

In the housing step ST103, the laminate 11 packaged in the outer bag 12 manufactured in the packaging step ST102 is housed in the case 13 in the manner described in [Case 13].

The method of storing in the case 13 is not particularly limited, and may be a manual packaging method or an automated or semi-automated packaging method using a device.

As described above, according to the bag product 1 according to the present invention, the stacking method and the arrow mark 111i allow the bag to be taken out one by one and the mouth of the bag to be opened with one hand. In addition, the arrow mark 111i can be used as a mark for taking out one laminate 11 from a group of successively discharged laminates when the laminates 11 are continuously manufactured using an apparatus. .
