It is a side view of the package body concerning a second embodiment. It is a figure for demonstrating the handle part which concerns on the comparative example 1. FIG. It is a figure for demonstrating the handle part which concerns on the comparative example 2. FIG.

  Next, a 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 30 in which eight paper rolls are packaged. Although the package 30 is not limited to a paper roll, the package 1 according to the present invention is generally a film roll such as a paper roll, particularly a kitchen paper roll or a toilet roll, and after taking out one It is particularly suitable for packages which need to be stored and which, as mentioned in the Background section, are frequently required to be carried and removed in the lodging industry and the like.

  A package 1 according to the present embodiment includes a gazette packaging main body 10 having an upper fusion bonding portion 41 and a lower fusion bonding portion 42 and a package 30 located therein, and a handle connected to the gusset packaging main body 10 And a unit 20. In the figure, a connecting portion between the gusset packaging main body portion and the handle portion is indicated by reference numeral 25.

  The lower part opening of the gusset packaging bag in which the upper part is fused to form the upper fusion part 41 in a state where the side parts 2E and 2E of the cylindrical packaging film are folded inside the bag and made flat After the package 30 is inserted, the lower part is fused to form the lower fusion part 42 for sealing the opening.

  Moreover, the package 1 which concerns on this embodiment is the state which packaged goods 30 such as a paper roll group, and the side part 2E, 2E in which the gusset package main-body part 10 was folded in in the flat state is opened. It has a gusset part 11, 11 to be formed, and each surface 12, 13, 14, 15 connected to this gusset part. Of the surfaces connected to the gusset 11, the surface connected to the upper fusion bonding portion 41 is the top surface 12, and the surface connected to the lower fusion bonding portion 42 is used as the bottom surface 15. The second surface connected to the top surface 12 and the bottom surface 15 and the respective gore portions 11 and 11 is a front surface 13 and a back surface 14. However, the front surface 13 and the back surface 14 are relative ones, and it is not limited which surface is the front surface.

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

  When packaging a roll paper suitable as the package 30, the roll paper in the gusset packaging main body 10 is such that four roll papers 30 are in contact with each other by two adjacent paper rolls at the barrel surface and the end face is a face It is desirable to arrange in such a manner that one end face is arranged so that each end face is arranged toward the upper and lower faces, and furthermore, the four paper roll groups arranged in this way are arranged in a plural stacked manner. . In the illustrated example, an embodiment in which two paper rolls and eight paper rolls are included is shown.

The packaging film constituting the gusset packaging main body 10 desirably has a thickness of 10 to 70 μm. The melting point is preferably 150 ° C. or less. Specifically, a polypropylene resin film and a polyethylene resin film are preferable in terms of cost and openability. The lower melting point of the packaging film is preferable for the formation of the upper and lower fused parts and the handle part described later because heat fusion processing can be performed at a low temperature, but if the melting point is excessively low, it is caused by friction or the like. A practical lower limit is 80 ° C., as it is more likely to be scratched or punctured. Examples of the polyethylene resin film include linear low density polyethylene films (LLDPE), low density polyethylene films (LDPE), and medium density polyethylene films (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 and cost. Suitable. Moreover, when packaging the thing with odor, such as a toilet roll with a smell, as the to-be-packaged thing 30, you may use an ethylene vinyl alcohol copolymer resin film and a polyethylene terephthalate resin film. Furthermore, it is a double-layered resin film in which a film made of a polyethylene resin or a film made of a polypropylene resin is laminated on one surface or both surfaces of an ethylene vinyl alcohol copolymer resin film and a polyethylene terephthalate resin film to enhance heat fusion. May be

  On the other hand, the handle portion 20 is constituted by a pair of flexible sheet members 21 and 22 connected to the top surface 12 of the gusset packaging main body portion 10. In the sheet members 21 and 22 constituting the handle portion 20, the lower portions 21A and 22A are positioned on both sides of the upper heat sealing portion 41 of the gusset package main body portion 10 and are separated from the upper sealing portion 41. The upper fusion bonded portion 41 is connected along the extending direction L1. Therefore, it is possible to hold the sheet members 21 and 22 and carry the package body 1 together with the gusset package body 10, and function as a handle. Further, in particular, the upper portions 21 B and 22 B of the sheet members 21 and 22 constituting the handle portion 20 are weakly adhered so as to be peelable above the upper heat sealing portion 41. Therefore, the package 1 can easily hold the upper portions of the sheet members 21 and 22 at the same time, and the package 1 can be easily carried by holding the sheet members 21 and 22 simultaneously. In addition, it is desirable to form in each of the sheet members 21 and 22 a finger hook 24 for putting a finger or a hand or a cut or perforation for forming the finger hook. The illustrated example is one in which the finger holes 24 are formed. If the finger hooking hole 24 is formed, it will be easier to carry by putting a finger or hand on it. Further, in this case, it is desirable that the finger hole 24 be formed in the weakly bonded portion 23 which is a portion including the portion where the weakly bonding is performed or the vicinity thereof. When the finger bonding holes 23 are formed in the weak bonding portion 23, it is easy to pass a finger or the like at the same time to each sheet material instead of individually, and it becomes suitable for carrying.

  The weakly bonded portion 23 is formed by adhesion with an adhesive such as a hot melt adhesive or an adhesive such as an acrylic adhesive, or fusion by ultrasonic fusion or heat fusion. The weakly adhesive portion 23 may be a releasable adhesion mode by, for example, reducing the number of adhesion portions, such as forming the adhesion portions as point adhesion or scattering point adhesion, or an adhesive agent or adhesive having weak adhesion. It is good also as adhesion mode which weakens the exfoliation strength of an adhesion part by using an agent, making it carry out weak fusion, etc. The weak adhesion part 23 should just be adhere | attached in the aspect which can peel each sheet material easily. Further, when the weakly bonded portion 23 is re-adhesive 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 make it possible to re-adhere and re-peel, the weakly-adhered portion 23 may be formed by a known releasable adhesive or the like.

  Since the upper portions 21B and 22B of the sheet members 21 and 22 have peelable weak adhesion as described above, the packaging body 1 can easily separate and separate the upper portions. In the package 1, the weak bonding portion 23 is above the upper fusion bonding portion 41 in the gusset packaging main body 10, and the lower portions 21A and 22A of the respective sheet materials 21 and 22 are the upper heat in the gusset packaging main body 10 The sheet members 21 constituting the handle portion 20 are connected along the extending direction L1 of the upper fusion bonding portion 41 at positions sandwiching the fusion bonding portion 41 and separated from the upper fusion bonding portion 41. 22 and the upper portions 21B and 22B of the sheet members 21 and 22 on the top surface 12 of the gusset package main body 10, particularly the top surface 12, when the upper portions 21B and 22B of the upper and lower portions 21B and 22B are separated. The portion L2 between the connecting portion 25 and the package body 10 is exposed between the sheet members 21 and 22. Therefore, when an opening is formed in the gusset packaging main body portion 10 by scissors or the like in the L2 between the connecting portions 25 between the lower portions 21A and 22A of the respective sheet materials 21 and 22 and the gusset packaging main body portion 10 in this top surface 12, each sheet While maintaining the shapes of the members 21 and 22, it is possible to take out the internal package 30 from the portion concerned. Therefore, even after taking out one or several packages from the opening, the upper portions 21B and 22B of the sheet materials 21 and 22 can be functioned as handles by overlapping and gripping them again. The to-be-packaged thing 30 which remains in the packaging main-body part 10 can be easily carried to another place. In particular, in the case where the finger holes 24 are formed in each of the sheet members 21 and 22, after the sheet members 21 and 22 are superimposed, the fingers or hands are passed through the finger holes 24 of both sheet members 21 and 22. Thus, it can be handled in the same manner as the handle portion 20 before being separated at the weakly bonded portion 23, which is more convenient.

  In the packaging body 1, in order to produce an effect suitably by forming an opening in L2 between the connection part 25 of lower part 21A, 22A of each sheet material 21,22 in the top surface 12, and the gazette package main body part 10 Preferably, the opening opening forming portion 26 is provided by perforation or the like in a portion L2 between the lower portions 21A and 22A of the sheet members 21 and 22 and the connection portion 25 between the gusset package main body portion 10 on the top surface 12. This makes it easy to form a suitable opening. The lengths and ratios of perforation cut portions and tie portions 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 one in which the perforation 26 is formed along the upper heat sealing portion 41 as illustrated. It is possible to form the opening by cutting off the upper heat seal part 41. In this case, a wide opening having the same size as the opening of the cylindrical packaging film is formed. That is, this is preferable because the sheet members 21 and 22 have an open upper bag body structure which becomes the handle portion 20 due to the structure of the gusset packaging main body portion 10. Further, when the handle portion 20 is held, the pulling direction of the sheet members 21 and 22 is perpendicular to the extending direction of the perforation 26 similar to the above-described L1. There is also an advantage that the eye 26 is unintentionally hard to tear. In particular, if the perforations are formed to be 80% or more, preferably 90% or more, more preferably 100% of the length of the upper heat sealing portion 41, the entire upper heat sealing portion 41 is the gusset packaging main body It can be easily detached from 10 and opened.

  The distance L1 between the lower portions 21A and 22A of the sheet members 21 and 22 and the connection portion between the gusset package main body portion 10 is the lower portions 21A and 22A of the sheet members 21 and 22 on the top surface 12 and the gusset package main portion 10 This is appropriately determined in consideration of the formation of an opening in L2 between the connecting portion 25 of and. In addition, when there is an excessive deviation in the connection portion 25 from the upper fusion bonding portion 41 of each sheet material 21, 22, the upper portions 21 B, 22 B of each sheet material 21, 22 are grasped or a finger passes through the finger hole 24 In this case, since the gusset packaging main body 10 is inclined, it is desirable that the distance between the connecting portion 25 of each of the sheet members 21 and 22 and the upper fusion bonding portion 41 be equal.

  The sheet members 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, a paper, a nonwoven fabric sheet, and a resin film are mentioned. Preferably, it is a resin film like the gusset packaging main body 10. A specific material is the same as the packaging film in the above-mentioned gusset packaging main part, however, the thickness and the kind thereof do not necessarily have to be the same as the gusset packaging main part. It is desirable to have a thickness that can ensure the strength required for the handle portion 20.

  The connection between the handle portion 20 and the gusset package main body portion 10 may be adhesion with an adhesive or a pressure-sensitive adhesive, or fusion such as heat fusion or ultrasonic fusion. Preferably, it is heat fusion that can be easily connected and can exhibit sufficient strength. That is, in the package 1, the sheet members 21 and 22 constituting the gusset package 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 particularly desirable.

  The package 1 of the present embodiment can be manufactured as follows. First, the packaging film formed in a tubular shape in advance is brought into a flat state in which both side portions are pushed into the inside of the cylinder, and two sheet materials 21 and 22 of resin film are disposed at positions to be top surfaces, While sealing one end of the cylindrical packaging film as the upper heat sealing portion 41 by heat sealing treatment, forming a perforation 26 along the sealing portion, and further heat sealing the sheet members 21 and 22 The packaging film is connected to form a three-way closed gusset packaging bag with the handle 20 attached and one closed. Furthermore, it is preferable that the upper portions of the sheet members 21 and 22 be weakly bonded to each other by this heat fusion treatment. As described above, since the respective sheet members do not move freely when the weakly bonded portion 23 is formed at the time of manufacturing the package 1, there is a possibility that the sheet members may be caught by the conveyance machine at the time of conveyance by a conveyor or the like in the subsequent stage. Reduced. Next, in a state where the packages 30 such as paper rolls are lined up, the package is inserted into the gusset packaging bag, and then the other opening is heat-sealed and sealed as the lower heat-sealed portion 42. As described above, the package 1 can be easily made in the same procedure as the conventional general gusset packaging, which is sealing the upper portion by heat fusion, inserting the package, and sealing the lower opening by heat fusion. It can be manufactured. The heat fusion treatment can be performed at 180 to 230 ° C. in accordance with a general method. Further, the sheet material and the gusset package main body may be connected to each other by attaching the sheet material by an adhesive or heat fusion after creating the gusset package main body including the package.

  Here, the length in the extending direction L1 of the upper fusion bonding portion 41 of each of the sheet members 21 and 22 can be equal to or shorter than the length of the upper heat fusion bonding portion 41. The illustrated example is shortened. For example, in the case of conventional gusset packaging of paper rolls such as a toilet roll or a kitchen paper roll, the excess margin portion above the heat-sealed portion in the upper portion is used as a handle portion. Since the widths of the sheet members 21 and 22 can be made shorter than 41, there is an advantage that when the sheet members 21 and 22 are films, the raw material cost for 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. In the second embodiment, the structure of the handle portion 20 is different from that of the first embodiment, and the other configuration is the same as that of the first embodiment.

  The handle portion 20 of the second embodiment is configured of a pair of sheet members 21 and 22 as in the first embodiment. However, unlike the first embodiment, each of the sheet members 21 and 22 has the lower portions 21A and 22A sandwiching the upper heat sealing portion 41, and at a position away from the upper sealing portion 41, The upper sides 21B and 22B of the sheet members 21 and 22 are not bonded to each other although they are connected to the surface portion 12 along the extending direction of the upper fusion bonding portion 41. The upper portions 21B and 22B of the sheet materials 21 and 22 of the second embodiment are folded back with the side closer to the upper heat fusion bonding 41 as a folding edge, and the overlapping surfaces are weak so as to be peelable. It is a weakly bonded portion 23 bonded.

  In the packaging body 10 of the second embodiment, the upper side of the sheet material becomes free and functions as a handle by peeling off the weak adhesion part 23 of the overlapping surface. It is desirable to form the finger holes 24 in the upper portions 21B and 22B as in the first embodiment. In addition, it is desirable that the weakly bonded portion 23 be re-adhesive and releasable.

  The package according to the second embodiment has an advantage that the handle 20 does not flutter as compared with the first embodiment because the respective sheet members 21 and 22 are integrated with the top surface 12. Moreover, since the sheet members 21 and 22 are exposed from the beginning, there is an advantage that it is easy to open.

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

  The package 1 according to each of the above embodiments can form the opening in the top surface 12 without breaking or damaging the sheet members 21 and 22 constituting the handle portion 20, so that the handle function can be exhibited even after the opening. It is easy to carry without spilling the package after opening. Further, in particular, when the perforation 26 is formed along the upper fusion bonding portion 41, since the bag structure has a large outlet which the entire upper portion is opened, the package 30 can be easily taken out, and after opening. In the above, it is easy to carry without spilling the inclusions.

  Next, with respect to the package 1 according to the present invention and the conventional example and the comparative example, the ease of opening, the ease of taking out the package, the ease of carrying before opening, the ease of carrying after opening, the opening It evaluated about the later appearance. The package was a toilet roll, and contained eight in the arrangement shown in FIGS. A packaging film made of polyethylene resin was used except for the package. In addition, in the case of the package 1 which makes a toilet roll a package object, a general consumer emphasizes the ease of carrying before opening, but in the accommodation industry etc. which distribute a toilet roll to each room, it is opened. Ease of handling, ease of taking out the package, ease of carrying after opening, and appearance after opening are emphasized, and in particular, ease of carrying after opening is emphasized.

  The conventional example is a conventional general toilet roll package in which a finger hole is formed in the surplus space above the fusion-bonded portion at the top of the gusset packaging bag. An example is a package concerning the present invention of the structure shown in FIG.4 and FIG.5. In Comparative Example 1, as shown in FIG. 6, heat sealing portions (dotted line portions indicated by reference numeral 123) are formed in a scattered manner over the entire upper edge portion of the packaging bag and sealed. The blind hole 124 is formed. The fusion bonded portion is structured to be opened as shown by pulling so as to peel off by hand or the like. Comparative Example 2 is an example in which, as shown in FIG. 7, the top surface portion 112 of the gusset package main body 110 is provided with finger holes 124 formed by slits directly on both sides of the upper fusion bonding portion 141. The results are as shown in Table 1 below, and the examples according to the present invention were evaluated as having no problems in all items, while the conventional examples and the comparative examples have problems x, some problems There was an item that was rated a certain △.

  If it is the package 1 of the structure which concerns on this invention, it is easy to open a packaging bag, it is easy to take out a to-be-packaged thing, and it is evaluated as a package which is easy to carry without spilling inclusions after opening.
