In general, primary packaging refers to the form in which products intended for sale are directly packaged. Secondary packaging refers to the form in which the products in the form of primary packaging are further packaged in boxes or bags according to the determined quantity. Goods are delivered to consumers in the form of primary or secondary packaging. In addition, tertiary packaging refers to the form in which products in the form of secondary packaging are placed in packaging boxes or the like for purposes such as bulk handling, warehousing, and transportation according to the determined quantity. In addition, a product that is in the form of primary packaging may be in the form of tertiary packaging instead of being in the form of secondary packaging.

For example, after winding the cylindrical side surface of a small cylindrical roll (corresponding to a "product") around a packaging film, the side surface of the packaging film is heat-sealed, and furthermore, it is positioned on the upper surface side and the lower surface side of the cylinder. There is a technique for primary packaging of small rolls by closing and heat-sealing packaging films (for example, see FIGS. 25 to 29 of Patent Document 1).

For bag makers, the product to be sold is the bag as the packaging material (see, for example, Patent Document 2). If the product is the intended product, the bag should be called a "product" to distinguish it from products that are not packaging materials (ordinary products, hereinafter also referred to as non-packaging material products). There is Moreover, the package which wraps a bag body may be called an outer bag.

Before a bag with fittings containing a non-packaging material product is displayed at a retail store, first, (1) bag-making process: the bag-making maker manufactures the bag body and stores it in the outer bag, (2) ) Transportation process 1: Deliver the bag body to the manufacturer of the non-packaging material product, (3) Bag supply process: Remove the bag body from the outer bag, (4) Filling process: Fill the bag body with the non-packaging material product, (5) Transportation process 2: The usual route is to transport the non-packaging material product filled in the bag to a retail store and then to general consumers.

The conventional bag-making process was performed in the following procedure. That is, bags with fittings, which are products produced by a bag-making machine, are once stocked in a container such as a tray, and are manually bundled into a fixed number of bags. The product bags with fittings, which are bundled by a certain number of sheets, are fixed by a binding means such as a rubber band, and then put into an outer bag with fittings, after which the fittings of the outer bag are attached. Closed. Furthermore, a plurality of outer bags with fittings are packed into a box. The box is shipped after being covered with a waterproof film to prevent dust and dirt from adhering and to prevent water from entering. All of these steps required manual labor.

In addition, the conventional bag feeding process was performed in the following procedure. That is, in order for a manufacturer of a non-packaging material product to fill a bag with a fitting with a non-packaging material product, the waterproof film is peeled off, the outer bag is removed from the box, the fitting of the outer bag is removed, and the bag is bundled. The bag with the fittings is taken out, the bundling means such as a rubber band is removed, and the bags with the fittings are returned to individual states. All of these steps also required manual labor.

Furthermore, the conventional filling process was performed in the following procedure. That is, individual bags with fittings are supplied to the bag body supply section of the filling machine. This process also required manual labor. The bags with fittings that are taken out one by one from the bag supply section of the filling machine are opened and filled with non-packaging material products. This process is performed by a filling machine.

(Outer bag containing product: first example)
Next, a product-filled outer bag 100 (first example) according to the present embodiment will be described with reference to FIGS. 1 to 3, 4 and 5. FIG. The product-filled outer bag 100 according to the present embodiment is a plurality of bags that are continuously or intermittently stacked in a row so that the bag bodies (p1, p2, p3, . . . , pn) that are products are partially overlapped. A product-filled outer bag 100 in which a body 3 is wrapped in a cylindrical outer bag 1 for outer packaging and integrated while maintaining the stacking state of the bag bodies, and the cylindrical outer bag 1 is self-adhesive. The base material 5 is a resin film having 71 at least.

Outer packaging refers to the form of packaging multiple units of products (not only products but also products that are individually packaged in primary packaging) for the purpose of sale (secondary packaging and tertiary packaging). includes both.) Moreover, the outer bag means that the outer packaging is particularly a bag body. Therefore, in the embodiments, the cylindrical outer bag refers to a bag having a cylindrical shape and used for outer packaging.

The resin film having self-adhesiveness as the base material 5 may be in a form in which the film itself has self-adhesiveness, or in a form in which an adhesive layer containing a resin having self-adhesiveness is provided on the surface of the film. good. Here, the term "self-adhesiveness" refers to the property that when films of the same material are laminated together, the films adhere to each other to such an extent that they cannot be separated from each other unless a certain amount of force is applied. As the self-adhesive resin film, for example, a film called a stretch film or a wrap film may be used. When the resin film having self-adhesiveness is in a form in which the film itself has self-adhesiveness, the material of the resin used for the film is not particularly limited, but examples include polyvinylidene chloride (PVDC), polyvinyl chloride (PVC ), polypropylene (PP), polyethylene (PE), ethylene vinyl acetate copolymer (EVA), polyethylene terephthalate (PET) or elastomer. When the self-adhesive resin film is in the form of providing an adhesive layer containing a self-adhesive resin on the surface of the film, the self-adhesive resin used for the adhesive layer is, for example, natural rubber or an elastomer. be. Further, the resin constituting the film or adhesive layer may be combined with a tackifier. Examples of tackifiers include, but are not limited to, terpene-based resins, rosin ester-based resins, and fatty acid-based or fragrance-based petroleum-based resins.

The thickness of the substrate 5 made of a single layer film is preferably about 0.2 mm to 1.5 mm, and the thickness of the substrate 5 made of a multilayer film is preferably about 0.4 to 2.0 mm. Further, the cylindrical outer bag 1 has a cylindrical shape that continuously extends with the same inner diameter along the length direction X of the cylinder when the inside of the cylinder is expanded. The inner diameter (diameter) is, for example, 1.5 to 65 cm, but is not limited to this range. Also, the upper and lower ends of the tubular shape may be open or may be closed by peelable sealing, gluing or heat welding, or binding.

As shown in FIGS. 1 and 2, the opening 6 is provided in the base material 5 along the length direction X of the tube. In this embodiment, the tubular outer bag 1 has at least one opening 6 . When the number of openings 6 is one, the substrate becomes one belt-like film by widening the openings. The tubular outer bag 1 shown in FIGS. 1 to 3 has one opening 6 . When the number of openings 6 is two, the base material becomes two belt-like films by widening the openings. Here, it is preferable to provide openings so that the widths of the two strip-shaped films have the same width. In addition, it is preferable that the opening 6 is formed over both ends of the cylindrical shape.

The cylindrical outer bag 1 is preferably rolled, skein-wound, or zigzag-folded with a flat cross section. A state in which the cross section is flat refers to a state in which cylindrical inner wall surfaces face each other and are in contact with each other. Being rolled includes bobbin winding, core winding and coreless winding. In the roll-wound and skein-wound forms, the cylindrical outer bag 1 has a flat cross section and the space inside the cylinder is degassed, so that the cylindrical outer bag 1 has a belt-like shape. It is preferable to wind so that the outer wall surfaces are in contact with each other. The volume of the rolled cylindrical outer bag can be reduced. In addition, even in the form of zigzag folding, that is, in the form of being folded in a zigzag shape, the cylindrical outer bag 1 has a flat cross section, so that the space inside the cylinder is deaerated, so that it is shaped like a belt. In such a shape, it is preferable that the flat outer wall surfaces are folded so that they are in contact with each other. The volume of the zigzag-folded cylindrical outer bag can be reduced.

In the product-filled outer bag 100 (first example) according to the present embodiment, the product-filled outer bag 100 includes a bag body (p1, p2, p3, p4, . It is preferable that the outer bag 1 is integrated while maintaining the stacking state of the bags.

In the product-filled outer bag 100 according to the present embodiment, a plurality of bags, which are products, are housed inside the cylinder of the cylindrical outer bag 1 for outer packaging. As shown in FIGS. 4 and 5, a bag body p1 as a product is a plastic resin bag body having an opening 8 and a housing portion 7, and a chuck 9 is provided along the edge of the opening 8. ing. The chuck 9 has a fitting structure and can be opened and closed. The chuck 9 has a female member having a strip-shaped female base and a female portion extending parallel to the opening 8, and a male member having a strip-shaped male base and male portion extending parallel to the opening 8. It is preferable to have a chuck structure that closes when the male part is engaged with the part. The male base part and the female base part are adhered to the inner wall surface of the base material of the bag. Alternatively, the chuck 9 may have a chuck structure in which the male part and the female part are integrally formed with the base material of the bag, and the male part is engaged with the female part to close the chuck. In this embodiment, the chuck 9 is not limited to these structures, and may have, for example, a structure in which the female portions are engaged with each other. The bags p2, p3, p4, . . . , pn, which are products, have the same structure as the bag p1. Since the bags (p1, p2, p3, p4, . . . , pn), which are products, have a flat structure, as shown in FIG. The state of the bag body 3 is possible. Here, in the cylindrical outer bag 1, the plurality of bag bodies 3 may be arranged continuously along the length direction X of the cylinder, or may be intermittently arranged, i.e. It may be an array having For the intermittent arrangement, for example, after a predetermined number of bags are stacked in a line so that they partially overlap, a gap is provided, and then the same number of bags are stacked in a line so that they partially overlap, An arrangement in which a gap is provided again and this is repeated is preferred. It becomes easy to confirm the number of bags. In this embodiment, the plurality of bag bodies 3 stacked in a row so as to partially overlap are integrated by forming the product-filled outer bag 100, so simply "the plurality of bag bodies 3 ” or “bag body 3”.

As shown in FIG. 2, the product-filled outer bag 100 encloses a plurality of bag bodies 3 in a cylindrical outer bag 1 . By overlapping the side ends extending in the length direction of the strip-shaped base material 5 (in FIG. 2, the opening, that is, the overlapped side end is indicated by reference numeral 6), the resin that is the base material 5 The films are self-adhered to form an overlapping portion 71 . The overlapping portion 71 is preferably folded at least once as shown in FIG. Further, by folding the sheet twice or more, the strength of temporary fixing can be increased. In the overlapping portion 71, the base materials are not sealed, adhered, or heat-sealed to each other. In the present embodiment, the peelable seal means bonding by a weakly adhesive or weakly adhesive peelable seal including an easy peel seal, and bonding means bonding by an adhesive agent including, for example, glue or tape. , and thermal welding is bonding by heat sealing, ultrasonic waves, high frequency, spot sealing, impulse sealer, or laser. Here, the width of the cylindrical outer bag 1 when containing the plurality of bags 3 is preferably slightly larger than the width of the plurality of bags 3, for example, 1 to 10 mm larger. It is preferable that the cylindrical outer bag 1 have a holding force to the extent that the arrangement of the plurality of bag bodies 3 is not disturbed when the overlapping portion 71 is formed. Since the bag bodies 3 can be more integrated while maintaining the stacking state, and excess air does not enter the inside of the cylinder, an increase in volume can be suppressed. By forming the overlapping portion 71, the cylindrical outer bag 1 is integrated while including the bag body 3. As shown in FIG.

The product-filled outer bag 100 not only enables a plurality of bags 3 to be handled as a bulk when carrying or storing, or both, but also allows the arrangement of the bags sequentially manufactured from the bag making machine. Since it can be fixed, it is possible to substantially reproduce in-line even if the bag-making machine and the filling machine are placed at different locations.

As shown in FIG. 2 , the tubular outer bag 1 with fittings has one overlapping portion 71 , and the overlapping portion 71 is preferably positioned on the stacking surface of the bags 3 . The bag body 3 can be easily wrapped with the outer bag in the form of joining palms together. Therefore, it is easy to manufacture with an apparatus having a simple structure. Moreover, when opening the overlapped portion 71, it can be performed in the form of a double door opening. More preferably, the overlapping portion 71 is positioned in the central portion of the stacking surface of the bags 3, as shown in FIG. The operation of forming or opening the overlapped portion 71 can be performed more stably, and the roll winding, skein winding, or zigzag folding can be performed more stably.

When the partition is formed by self-adhesion, it is preferable to form the partition by bringing the inner wall surfaces of the facing base materials into close contact with each other while pressing a roll against a portion corresponding to the non-arranged portion. An exemplary method is also described with reference to FIG. 16 where the partition is formed by a peelable seal, adhesive or heat weld. The partition 41 is preferably formed by heat-sealing the facing inner wall surfaces of the substrates 5 while pressing the heat sealer 43 against the portion corresponding to the non-arranged portion 40 . The heat sealer 43 thermally welds the facing base materials 5 to each other, but the temperature is set within a temperature range that does not cut them by fusion. The heat sealer 43 is brought into contact with the base material at the timing when the non-arranged portion 40 of the bag is reached by the flow in the longitudinal direction of the tubular shape, thereby forming a partition (thermally welded portion in FIG. 16) 41 . Alternatively, the partition may be formed by bonding the inner wall surfaces of the substrates facing each other. Further, it is more preferable that the non-arrangement portions are arranged on both sides of the partition.

Perforations for separation may be further provided where the partition is provided. A predetermined number of bags, which are products, are accommodated in the cylindrical outer bag, and by cutting off the perforations, subdivision management is facilitated.
