Description

  The present invention relates to a packaging body in which a plurality of tissue cartons stacked in the height direction are integrally packaged with a resin film, and a method for manufacturing the same. More specifically, the present invention relates to a package having a transport handle formed integrally with the package by a part of the resin film on the upper surface of the package, and a method for manufacturing the package.

  In general, disposable sanitary paper containing cartons such as tissue paper is marketed in a state where a plurality of cartons are stacked and integrally packaged with a resin film.

  As such a package in which a plurality of packages to be packaged (disposable sanitary paper with cartons) are integrally packaged, a package having a handle for transportation is known for the convenience of carrying by the purchaser. . Such a package has the advantage that even a disposable paper product that is relatively bulky and heavy can be easily transported because the handle can be carried by hand.

  For example, the package 100 shown in FIG. 9 is an example in which five cartons of tissue paper (tissue cartons) are used as packages, and five tissue cartons 2 are stacked in the height direction. Then, it is packaged integrally with the resin film 4 and is provided with a band-like handle 10 across the upper surface 6 (see, for example, Patent Documents 1 to 4).

  By the way, in the above-described packaging body in which the belt-like film is welded to the packaging body main body, the grip film is peeled off from the resin film covering the packaging body due to poor welding, and the role as a grip. There was a problem that some products did not fulfill the requirements.

  In addition, the belt-like film is welded to both sides facing the long side direction (tissue width direction of the tissue carton: longitudinal direction) across the top surface of the packaging body, so it lacks stability during carrying and has a short side. In some cases, the carton may be damaged due to the shaking in the direction (depth direction of the tissue carton). In other words, there are concerns about the occurrence of defective products, such as when the hand hits the carton, the perforation formed in the tissue outlet is broken, or when the carton hits the surrounding object, the carton is scratched or dented. It was. Furthermore, when carrying, there was a problem that the corner of the carton as a box hits the hands and feet, causing pain and discomfort.

  Moreover, in the package as described above, a handle film must be prepared and welded separately from the resin film for carton packaging, which is wasteful from the viewpoint of the manufacturing process and cost. Furthermore, in order to confirm the presence or absence of the film for the handle in the package, it is necessary to recognize the color with a camera by coloring the film or printing an opaque mark, and confirming the quality of the welded part. Therefore, it is necessary to measure the irregular reflection of the light at the welded part. That is, there is a problem that not only the printing cost is increased, but also the aesthetic appearance of the whole package is impaired, which affects the consumer's willingness to purchase.

  Therefore, a tissue carton package that does not require welding of a belt-like film as a handle and has excellent stability during carrying is desired.

  The present invention has been made to solve the above-described problems of the prior art, and prevents the occurrence of defective products due to poor welding of the grip film and reduces the damage to the tissue cartons that occur during transportation. It is intended to provide a package having excellent time stability and a method for producing the same.

  As a result of intensive investigations to solve the problems of the prior art as described above, the present inventor has obtained a handle that has been conventionally formed by welding another belt-like resin film to the package body. The present invention has been completed by conceiving that the above-mentioned problems can be solved by forming a part of the resin film constituting the film integrally with the package body. That is, the present invention is as follows.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and changes, modifications, and improvements can be added without departing from the scope of the invention.

[1] Package of the present invention:
FIG. 1 is a perspective view showing Embodiment 1 of the package of the present invention. The package 1 is integrally packaged with a resin film 4 in a state where five tissue cartons 2 are stacked in the height direction, and has a handle 8 for transportation on its upper surface 6. And the handle 8 is formed integrally with the package body 3 using a part of the resin film 4 constituting the package 1, and the long side direction of the package 1 is formed at the center of the upper surface 6 of the package 1. It is formed substantially in parallel.

  The lower surface 7 of the package 1 of the present invention is sealed by caramel packaging, and the upper surface 6 is sealed by the same method, and at the same time, the handle 8 is formed integrally with the package body 3. Specifically, as shown in FIG. 8, among the resin films 4 extending to the upper surface side of the tissue carton, the short side extending portion 40 extending to the short side faces the upper surface 6 of the tissue carton 2. The long side extending portion 42 that extends to the long side has a length in the long side direction on the short side folding portion 44. It is folded so that it becomes short toward the edge part 50, and it is set as the long side side folding part 46, and the two long side side folding parts 46 which oppose are affixed on the short side side folding part 44 Further, the front end portions 48 of the two opposing long side folding portions 46 are bonded to each other to form the flap portion 12 that becomes the handle 8 for transportation.

  Caramel wrapping refers to a sealing form in which an extra length portion of a film is taken so as to protrude outward from the end face of a main body, and the extra length portion is folded in order and sealed, like a cigarette packaging bag. When the packaged body is a box-shaped body such as tissue carton 2, the characteristics are most utilized. In other words, when the packaged body is a flexible article, the packaged body may be damaged by the pressure applied to the packaged body during welding. If it is a box-shaped body which has intensity | strength more than predetermined, there is no fear of the damage at the time of packaging, and a to-be-packaged body can be exactly covered with the resin film 4 along the shape.

  Moreover, in the package 1 of this invention, the contact surface of the short side folding part 44 of the resin film 4 and the upper surface 6 of the tissue carton 2 is from one long side of the tissue carton 2 to the other long side. It is preferable that it is formed in a rectangular shape that covers (see step 3 in FIG. 8). This is for obtaining a more durable and stable package 1 by ensuring the area of the overlapping part of the short side folding part 44 and the long side folding part 46 as wide as possible. The short side folding part 44 and the long side folding part 46 are firmly overlapped and adhered to the tissue carton 2 which is the packaged body, and welded so that a strong and stable packaging body 1 is obtained. Although this is effective, this is a packaging method that is possible because the packaged body is a box-shaped body having a predetermined strength or more. For example, in a handle-integrated package often found in the field of sanitary products such as toilet paper and disposable diapers, the package is a flexible article. It is difficult to wrap. Accordingly, there is a problem that the upper surface sealing portion provided with the handle is lifted from the package body during transportation, and a load is applied to the upper surface end portion of the package body. The present invention can provide a package 1 that covers the entire body firmly and is excellent in stability during transportation without applying a load only to the local area of the package.

  In the present invention, the handle 8 is not limited in shape or structure as long as the package body 3 can be carried. At least the flap part 12 is provided with an opening part 14 into which a finger can be inserted or an opening part to be the opening part 14 and a holding part 16 processed so as to be grasped in the palm. A member having sufficient strength to withstand transportation is included in the handle 8 referred to in this specification. Note that the planned opening portion does not function as the opening portion 14 as it is, but a member that can form the opening portion 14 by applying some operation such as breaking the perforation, that is, the opening portion 14. The precursor of Moreover, although it is a formation position of the handle 8, it is desirable that it is formed in the center part of the upper surface 6 of the package 1 substantially parallel to the long side direction of the package 1 from a viewpoint of the stability at the time of conveyance.

  The opening 14 can be formed by performing a series of processes such as perforation, punching, or making a cut 15 in a desired shape on the flap portion 12, and the shape is convenient for grasping. It only has to satisfy. For example, the packaging body 1 shown in FIGS. 1 to 3 is an example provided with a handle 8 provided with an opening 14 punched into a bowl shape, but in addition to the handle 8 shown in FIGS. 4 to 7. Similarly, the opening 14 can take various shapes.

  The planned opening portion is a series of processes such as making a relatively long cut in the flap portion 12 and connecting the gaps with short linear discontinuities or dot discontinuities, or perforating into a desired shape. As long as the shape of the handle 8 satisfies the convenience of grasping, it can be formed by breaking intermittent discontinuities and perforations. For example, the handle 8 shown in FIGS. 4 to 7 is an example in which the opening 14 is provided, but by performing the processing as described above, it is possible to form a planned opening having the same shape as the opening 14. Is possible.

  In addition, the shape of the holding portion 16 is not particularly limited as long as it can be grasped comfortably as the handle 8. However, the handle 8 has a substantially trapezoidal shape in terms of ease of manufacturing and ease of grasping. The flap portion 12 is preferably cut and formed as necessary.

  As described above, the handle 8 of the packaging body 1 of the present invention has a comfortable grip feeling compared to the conventional band-shaped handle 10 that is excellent in stability during transportation and easy to bite into the palm when grasped. .

  There is no restriction | limiting in particular about the material of the resin film 4 which comprises the package 1 of this invention, Usually, resin, such as polyethylene and a polypropylene used for a packaging bag, can be used. Among these, polyethylene is preferable in terms of stretchability and strength. The thickness of the film varies depending on the type and weight of the package body, but when the tissue carton 2 is a package body, the film thickness is preferably 20 μm to 35 μm. Since the thickness of the conventional handle film is approximately 40 μm, it is preferable to use the resin film 4 having a thickness of 20 μm or more because sufficient strength can be obtained when the handle 8 is formed by bonding.

  In addition, you may provide the cut part 22 and the tape 32 for cutting | disconnection for opening the package 1 and taking out the tissue carton 2 which is a package body in the package of this invention. By providing such a cut portion 22 and a separating tape 32, the tissue cartons 2 as the contents can be taken out relatively easily and without requiring force. For example, the package 1 shown in FIG. 2 is provided with two vertical perforations 20 and 21 on one side of the wide side of the package 1 (the wide side facing the short side direction of the package), and the cut portion 22. Further, in the example in which the knob 23 is formed at the upper end of the cut portion 22, the packaging body 1 of the present invention has a handle-integrated type, for example, all four side surfaces of the packaging bag 1 as shown in FIG. In an example in which a plurality of separating tapes 32 are provided over the circumference and a knob 33 is formed at the tip of each of the separating tapes 32, the characteristics can be exhibited, which is preferable.

  In the conventional package, in order to reliably weld the band-shaped handle 10 to the package body 3, as shown in FIG. A length corresponding to the height was secured in the vertical direction. However, as shown in FIG. 10, when the separation tape 32 is provided over the entire circumference of the four side surfaces of the package, the sticking portion 18 may become an obstacle, and the length of the sticking portion 18 in the vertical direction is shortened. I had to be addicted. That is, the area of the affixing portion 18 was reduced, which led to problems such as poor welding and the ease with which the strip-shaped handle 10 was detached. In the package 1 of the present invention, as shown in FIG. 3, since the handle 8 is formed on the upper surface 6 of the package body 3, the function as the handle 8 is provided even if the separation tape 32 is provided at a desired position. Is sufficiently maintained and preferred. The formation position and the number of the separation tapes 32 are not particularly limited, and a plurality of separation tapes 32 may be formed at positions where the tissue cartons 2 can be easily taken out.

[2] Method for producing the package of the present invention:
The package 1 of the present invention can be produced according to a conventionally known method for producing a package. For example, in the packaging body 1 shown in FIGS. 1 to 3, a plurality of stacked tissue cartons 2 are wound around with a resin film 4, and the edges of the resin film 4 that overlap each other are bonded to each other to form a body bonding portion It is an example of a package that is formed and the lower surface 7 of the package body 3 is sealed with caramel packaging.

  FIG. 8 is a process diagram showing the manufacturing process of the handle 8 of the package 1 of the present invention. As described above, the upper surface 6 of the package (step 1) in a state where the lower surface 7 of the package body 3 is sealed by caramel packaging is sealed while forming the handle 8. First, of the resin film 4 extending to the upper surface side of the tissue carton 2, the short side extending portion 40 extending to the short side is folded toward the upper surface 6 of the tissue carton 2, and the short side folding portion 44 (steps 2 and 3). Next, the long side extending portion 42 extending to the long side is folded on the short side folding portion 44 so that the length in the long side direction becomes shorter toward the edge portion 50. , The long side folding portion 46 (steps 4 and 5). Then, the two opposing long side folds 46 are pasted from above the short side folds 44 so as to be in close contact with the tissue carton 2, and then the tips 48 of the long side folds 46 are pasted together. Then, the flap portion 12 that becomes the handle 8 for transportation is formed (step 6).

  At this time, the contact surface between the short side folding part 44 of the resin film 4 and the upper surface 6 of the tissue carton 2 is formed in a rectangular shape covering from one long side of the tissue carton 2 to the other long side. Is preferred.

  In addition, for the adhesion of the resin film in the production of the package 1 of the present invention, for example, conventionally known methods such as heat sealing, ultrasonic welding, and adhesion using an adhesive can be used. Since it can do, it is preferable to weld by a heat seal. As the welding conditions in the heat seal, it is 180 ° C. to 220 ° C. for about 3 seconds for forming the body bonding portion, 180 ° C. to about 180 ° C. for sealing the upper surface 6 and the lower surface 7 and forming the handle 8 on the upper surface 6. Heating at 210 ° C. for 1 second is preferred. That is, the attachment of the long side folding part 46 to the short side folding part 44 and the sticking of the end parts 48 of the long side folding part 46 are performed by heating at 180 ° C. to 210 ° C. for 1 second. Are preferred.

  The package of the present invention is suitably used as a package having a bulky box-like product that is difficult to carry, such as sanitary paper with cartons such as tissue paper. The package of the present invention is a package that realizes cost reduction during production and convenience during transportation, and has a great industrial utility value.
