It is a figure for demonstrating the handle part which concerns on Comparative Example 2.

Next, the first embodiment of the package of the present invention will be described in detail with reference to FIGS.

The package 1 according to the present embodiment is a package of eight paper rolls as the object to be packaged 30. The object to be packaged 30 is not limited to a paper roll, but the package 1 according to the present invention is generally a paper roll, particularly a film package such as a kitchen paper roll or a toilet roll, and after one is taken out. It is particularly suitable for packages that need to be stored and, as mentioned in the background technology section, that need to be frequently carried and taken out in the accommodation industry and the like.

The package 1 according to the present embodiment has a gusset packaging body 10 having an upper fusion section 41 and a lower fusion section 42 and an object to be packaged 30 located inside, and a handle connected to the gusset packaging body 10. It has a part 20 and. In the figure, the connecting portion between the gusset packaging main body portion and the handle portion is indicated by reference numeral 25.

The gusset packaging main body 10 is a lower opening of the gusset packaging bag in which the side portions 2E and 2E of the tubular packaging film are folded inside the bag to be flattened and the upper portion is fused to form the upper fusion portion 41. It can be manufactured by opening the opening, inserting the object to be packaged 30, and then fusing the lower part to form the lower fusing portion 42 that seals the opening.

Further, in the packaging body 1 according to the present embodiment, in a state where the object to be packaged 30 such as a paper roll group is packaged, the side portions 2E and 2E folded in the gusset packaging main body 10 in the flat state are opened. It has gusset portions 11 and 11 to be formed, and surfaces 12, 13, 14 and 15 connected to the gusset portions. Of the surfaces connected to the gusset portion 11, the surface connected to the upper fused portion 41 is the top surface 12, and the surface connected to the lower fused portion 42 is used as the bottom surface 15. The second surfaces that are connected to the top surface 12 and the bottom surface 15 and the gusset portions 11 and 11 are the front surface 13 and the back surface 14. However, the front surface 13 and the back surface 14 are relative to each other, and which surface is the front surface is not limited.

The upper fusion section 41 and the lower fusion section 42 are formed by known fusion techniques such as heat fusion and ultrasonic fusion. Preferably, it is by heat fusion.

When wrapping roll paper suitable as the object to be packaged 30, the roll paper is placed in the gusset packaging main body 10 so that the four roll papers 30 are in contact with each other and two adjacent paper rolls are in contact with each other on the body surface and the end faces are face to face. It is desirable that the paper rolls are arranged so as to be one and one end face is arranged toward the upper and lower surfaces, or a group of four paper rolls arranged in this way are stacked one above the other. .. In the illustrated example, a mode in which eight paper rolls are included in two stages is shown.

The packaging film constituting the gusset packaging main body 10 preferably has a thickness of 10 to 70 μm. The melting point is preferably 150 ° C. or lower. Specifically, a polypropylene resin film and a polyethylene resin film are desirable in terms of cost and openability. It should be noted that a packaging film having a lower melting point is preferable in forming an upper fusion zone, a lower fusion zone, and a handle portion, which will be described later, because heat fusion treatment can be performed at a low temperature. The practical lower limit is 80 ° C., as it increases the risk of scratches and holes. Examples of the polyethylene resin film include a linear low density polyethylene film (LLDPE), a low density polyethylene film (LDPE), and a medium density polyethylene film (MDPE). Among them, in the present invention, ^{a linear low density polyethylene film layer (LLDPE) having a density of 0.910 to 0.940 g / cm 3} and a melting point of 110 to 120 ° C. is particularly preferable in terms of heat fusion property and cost. Suitable. Further, when packaging an odorous material such as a scented toilet roll as the object to be packaged 30, an ethylene vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film may be used. Further, it is a multi-layered resin film in which a polyethylene resin film or a polypropylene resin film is laminated on one or both sides of an ethylene vinyl alcohol copolymer resin film or a polyethylene terephthalate resin film to improve heat-sealing properties. You may.

On the other hand, the handle portion 20 is composed of a pair of flexible sheet materials 21 and 22 connected to the top surface 12 of the gusset packaging main body portion 10. The sheet materials 21 and 22 constituting the handle portion 20 are located at positions where the lower portions 21A and 22A sandwich the upper heat fusion portion 41 in the gusset packaging main body portion 10 and are separated from the upper fusion portion 41. The upper fused portion 41 is connected along the extending direction L1. Therefore, it is possible to carry the packaging body 1 together with the gusset packaging main body 10 by grasping the sheet materials 21 and 22, and it functions as a handle. Further, in particular, the sheet materials 21 and 22 constituting the handle portion 20 are weakly adhered to each other so that their upper portions 21B and 22B can be peeled off above the upper heat-sealing portion 41. Therefore, the packaging body 1 can easily grasp the upper portions of the sheet materials 21 and 22 at the same time, and the packaging body 1 can be easily carried by grasping the sheet materials 21 and 22 at the same time. It is desirable that each of the sheet materials 21 and 22 is formed with a finger hook hole 24 for putting a finger or a hand, or a cut or a perforation for forming a finger hook hole. In the illustrated example, the finger hook hole 24 is formed. If the finger hook hole 24 is formed, it will be easier to carry with a finger or a hand. Further, in this case, it is desirable that the finger hook hole 24 is formed in the weakly bonded portion 23, which is a portion including the weakly bonded portion or a portion further thereof. When the weakly bonded portion 23 is formed with a finger hook hole, it becomes easy to pass a finger or the like through each sheet material at the same time rather than individually, which makes it more suitable for carrying.

The weakly bonded portion 23 is formed by bonding with an adhesive such as a hot melt adhesive or a pressure-sensitive adhesive such as an acrylic pressure-sensitive adhesive, fusion by ultrasonic fusion, heat fusion, or the like. The weakly bonded portion 23 may be a peelable bonding mode by reducing the number of bonded portions, for example, by forming the bonded portions into point-bonded parts or forming the bonded parts so as to scatter the point-bonded parts, or an adhesive having a weak adhesive force or adhesiveness. The bonding mode may be such that the peeling strength of the bonded portion is weakened by using an agent or weakly fusing. The weakly bonded portion 23 may be bonded in such a manner that the sheet materials can be easily peeled off from each other. Further, if the weakly bonded portion 23 can be re-bonded and re-peelable, the upper portion of each sheet material can be separated and then re-bonded to form a handle portion. In order to enable re-adhesion and re-peelability, the weakly-adhesive portion 23 may be formed with a known re-peelable adhesive or the like.

As described above, the upper parts 21B and 22B of the sheet materials 21 and 22 of the package 1 are detachably weakly adhered to each other, so that the upper parts can be easily separated and separated from each other. In the package 1, the weakly bonded portion 23 is above the upper fused portion 41 in the gusset packaging main body 10, and the lower portions 21A and 22A of the sheet materials 21 and 22 are the upper heat in the gusset packaging main body 10. Since the upper fused portion 41 is connected along the extending direction L1 of the upper fused portion 41 at a position sandwiching the fused portion 41 and at a position separated from the upper fused portion 41, each sheet material 21 constituting the handle portion 20 is formed. When the upper parts 21B and 22B of 22 are separated by the weak adhesive portion 23 and separated from each other, the lower parts 21A and 22A of the sheet materials 21 and 22 and the gusset on the top surface 12 of the gusset packaging main body 10, particularly the top surface 12. L2 between the connecting portions 25 with the packaging main body 10 is exposed between the sheet materials 21 and 22. Therefore, when an opening is formed in the gusset packaging main body 10 by scissors or the like in L2 between the lower portions 21A and 22A of the sheet materials 21 and 22 on the top surface 12 and the connecting portion 25 between the gusset packaging main body 10 and each sheet. While maintaining the shape of the materials 21 and 22, the packaged object 30 inside can be taken out from the portion. Therefore, even after one or several packages to be packaged are taken out from the opening, the upper parts 21B and 22B of the sheet materials 21 and 22 can be overlapped and grasped again to function as a handle. The object to be packaged 30 remaining on the packaging body 10 can be easily carried to another place. In particular, when the finger hook holes 24 are formed in each of the sheet materials 21 and 22, after the sheet materials 21 and 22 are overlapped, a finger or a hand is passed through the finger hook holes 24 of both sheet materials 21 and 22. As a result, the weakly bonded portion 23 can be handled in the same manner as the handle portion 20 before being separated, and is more convenient.

In the package 1, the opening is preferably formed in L2 between the lower portions 21A and 22A of the sheet materials 21 and 22 on the top surface 12 and the connecting portion 25 between the gusset packaging main body 10 and the gusset packaging body 10. It is desirable that an opening opening forming portion 26 is provided at L2 between the lower portions 21A and 22A of the sheet materials 21 and 22 on the top surface 12 and the connecting portion 25 between the gusset packaging main body portion 10 by perforations or the like. In this way, it becomes easy to form a suitable opening. The lengths and ratios of the perforated cut portion and the tie portion are appropriately designed according to the material of the packaging film and the like. A more preferable example of the opening opening forming portion is that the perforation 26 is formed along the upper heat-sealing portion 41 as shown in the illustrated example. The opening can be formed by cutting off the upper heat-sealing portion 41. In this case, a wide opening that is the same size as the opening of the tubular packaging film is formed. That is, in this case, the structure of the gusset packaging main body 10 is preferable because the sheet material 21 and 22 have a bag structure with an open top as the handle 20. Further, when the handle portion 20 is held, the pulling direction of the sheet materials 21 and 22 is perpendicular to the extending direction similar to the above L1 of the perforation 26, so that the sewing machine is carried when unopened. There is also an advantage that the eyes 26 are hard to tear unintentionally. In particular, if the perforations are formed over 80% or more, preferably 90% or more, more preferably 100% of the length of the 26 upper heat-sealing portion 41, the entire upper heat-sealing portion 41 can be formed as the gusset packaging main body portion. It can be easily separated from 10 and opened.

The distance of L1 between the lower parts 21A and 22A of the sheet materials 21 and 22 and the connecting portion of the gusset packaging main body 10 is the distance between the lower parts 21A and 22A of the sheet materials 21 and 22 and the gusset packaging main body 10 on the top surface 12. It is appropriately determined in consideration of the fact that an opening is formed in L2 between the connecting portions 25 with and. Further, if the connecting portion 25 from the upper fused portion 41 of each sheet material 21 and 22 is excessively displaced, the upper parts 21B and 22B of each sheet material 21 and 22 are grasped or a finger is passed through the finger hook hole 24. At that time, since the gusset packaging main body portion 10 is tilted, it is desirable that the distance between the connecting portion 25 of each sheet material 21 and 22 and the upper fusion portion 41 be equal.

The sheet materials 21 and 22 may be any flexible sheet that can be connected to the top surface 12 of the gusset packaging main body 10 and has the strength required for carrying. For example, paper, non-woven fabric sheet, resin film can be mentioned. Preferably, it is a resin film like the gusset packaging main body 10. The specific material is the same as the packaging film in the gusset packaging main body, but the thickness and type do not necessarily have to be the same as those in the gusset packaging main body. It is desirable that the thickness is such that the strength required for the handle portion 20 can be secured.

The connection between the handle portion 20 and the gusset packaging main body portion 10 includes adhesion by an adhesive or an adhesive, heat fusion, ultrasonic fusion, or the like. Preferably, it is heat fusion that can be easily connected and can exhibit sufficient strength. That is, in the packaging body 1, the sheet materials 21 and 22 constituting the gusset packaging main body 10 and the handle 20 are made of the above film suitable for heat fusion, and both are connected by heat fusion. Is especially desirable.

The package 1 of the present embodiment can be manufactured as follows. First, the wrapping film formed in the shape of a cylinder in advance is made into a flat state by pushing both side portions into the inside of the cylinder, and the sheet materials 21 and 22 of the two resin films are arranged at positions to be the top surfaces, respectively. One opening of the tubular packaging film is sealed as an upper heat-sealing portion 41 by heat-sealing treatment, perforations 26 are formed along the sealing portion, and sheet materials 21 and 22 are heat-sealed. To form a three-way closed gusset packaging bag to which the handle 20 is attached and one is closed. Further, it is preferable that the upper portions of the sheet materials 21 and 22 are weakly adhered to each other by this heat fusion treatment. If the weakly bonded portion 23 is formed during the production of the package 1 in this way, each sheet material does not move freely, so that the sheet material may be caught in the transfer machine during transportation by a conveyor or the like in the subsequent stage. It will be reduced. Next, in a state where the objects to be packaged such as paper rolls 30 are arranged side by side, they are inserted into the gusset packaging bag, and then the other opening is heat-sealed and sealed as the lower heat-sealed portion 42. In this way, the package 1 can be easily manufactured by the procedure of sealing the upper part by heat fusion, inserting the object to be packaged, and sealing the lower opening by heat fusion, which is almost the same as the conventional general manufacturing of the gusset package. Can be manufactured. The heat fusion treatment can be performed at 180 to 230 ° C. according to a general method. Further, in the connection between the sheet material and the gusset packaging main body, the sheet material may be retrofitted by an adhesive or heat fusion after the gusset packaging main body containing the object to be packaged is created.

Here, the length of the extending direction L1 of the upper fused portion 41 of each of the sheet materials 21 and 22 can be the same as or shorter than the length of the upper heat fused portion 41. The illustrated example is shortened. For example, in the case of conventional gusset packaging of paper rolls such as toilet rolls and kitchen paper rolls, the surplus margin portion above the upper heat-sealing portion is used as the handle portion, but the main package 1 is the upper heat-sealing portion. Since the width of the sheet materials 21 and 22 can be shortened as compared with 41, when the sheet materials 21 and 22 are used as a film, there is an advantage that the raw material cost related to the film can be reduced.

Next, a second embodiment of the package of the present invention will be described with reference to FIGS. 4 and 5. The second embodiment has a different structure of the handle portion 20 from the first embodiment, and other configurations are the same as those of the first embodiment.

The handle portion 20 of the second embodiment is composed of a pair of sheet material 21 and a sheet material 22 as in the first embodiment. However, unlike the first embodiment, in each of the sheet materials 21 and 22, the lower parts 21A and 22A are located so as to sandwich the upper heat-sealed portion 41 and are separated from the upper fused portion 41. Although the upper fused portion 41 is connected to the surface portion 12 along the extending direction, the upper side 21Bs and 22Bs of the sheet materials 21 and 22 are not adhered to each other. In each of the sheet materials 21 and 22 of the second embodiment, the upper portions 21B and 22B are folded back with the side close to the upper heat-sealing 41 as a folded edge, respectively, and the overlapping surfaces thereof are weak so that they can be peeled off. It is a weakly bonded portion 23 that is bonded.

By peeling off the weakly bonded portion 23 of the overlapping surface of the package 10 of the second embodiment, the upper side of the sheet material becomes free and functions as a handle. It is desirable that the finger holes 24 are formed in the upper portions 21B and 22B as in the first embodiment. Further, it is desirable that the weakly bonded portion 23 can be re-bonded and re-peeled.

The package of the second embodiment has an advantage that the handle portion 20 does not flutter as compared with the first embodiment because the sheet materials 21 and 22 are integrated with the top surface portion 12. Further, since the space between the sheet materials 21 and 22 is exposed from the beginning, there is an advantage that the package is easy to open.

The package 10 of the second embodiment can also be manufactured in the same manner as the first embodiment.

Since the package 1 of each of the above embodiments can form an opening opening on the top surface 12 without breaking or damaging the sheet materials 21 and 22 constituting the handle portion 20, the handle function can be exhibited even after opening. It is easy to carry without spilling the packaged item after opening. Further, in particular, when the perforation 26 is formed along the upper fused portion 41, the bag structure has a large outlet that opens the entire upper portion, so that the packaged object 30 can be easily taken out and after opening. It will be easy to carry without spilling the inclusions.

Next, with respect to the package 1 and the conventional example and the comparative example according to the present invention, the ease of opening, the ease of taking out the packaged object, the ease of carrying before opening, the ease of carrying after opening, and the opening of the package I evaluated the appearance later. The packaged material was a toilet roll, and eight pieces were housed in the arrangement shown in FIGS. 1 and 4. A polyethylene resin packaging film was used except for the object to be packaged. In the case of the package 1 in which the toilet roll is the object to be packaged, general consumers place importance on portability before opening, but in the accommodation industry where the toilet roll is distributed to each room, the package is opened. Ease of removal, ease of taking out the packaged item, ease of carrying after opening, and appearance after opening are emphasized, and in particular, ease of carrying after opening is emphasized.

A conventional example is a conventional general toilet roll package in which a finger hole is formed in a surplus allowance above the fused portion at the upper part of the gusset packaging bag. An example is a package according to the present invention having the structures shown in FIGS. 4 and 5. In Comparative Example 1, as shown in FIG. 6, heat-sealed portions (dotted line portions indicated by reference numeral 123) are scatteredly formed and sealed over the entire upper edge portion of the packaging bag, and the heat-sealed portions are fingered. The hook hole 124 is formed. The fused portion has a structure that can be opened as shown by pulling it so as to be peeled off by hand or the like. As shown in FIG. 7, Comparative Example 2 is an example in which the top surface portion 112 of the gusset packaging main body 110 is provided with finger hook holes 124 formed by slits directly on both sides of the upper fused portion 141. The results are shown in Table 1 below, and the examples according to the present invention were evaluated as having no problem in all items, whereas the conventional example and the comparative example had a problem ×, and there were some problems. Some items were evaluated as △.

The package 1 having the structure according to the present invention is evaluated as a package that is easy to open the packaging bag, easy to take out the packaged object, and is easy to carry without spilling the package after opening.
