Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 According to the present invention, the thickness of the plastic film for wrapping the toilet paper roll can be reduced by reinforcing the handle portion, and no swelling occurs due to temperature and pressure, and it is difficult for dust and foreign matter to enter. The present invention relates to a plastic film-made toilet paper roll package containing a plurality of toilet paper rolls.

[0002]

[Prior art]

 In many cases, toilet paper rolls are sold and packaged in such a manner that four 2 × 2 toilet paper rolls are stacked in three layers and stored in a plastic film bag made of polyethylene or the like.

[0003] That is, in such a toilet paper roll sales and packaging form, the upper end of the toilet paper roll package in which the toilet paper roll is stored in a certain tension state is one of two opposite openings. A fold is formed in which the side is folded inside the other two sides, and is reinforced by a heat-sealed portion applied vertically and horizontally together with one reinforcing plastic film, and further surrounded by the four heat-sealed portions vertically and horizontally. A slit for forming a finger through hole was provided in the five-layered part including the reinforced plastic film in the enclosed section so that it could be suspended by hand and a handle was formed. .

[0004] The opening at the other end of the packaging bag having the handle portion formed as described above is widened, and four 2 x 2 toilet paper rolls are stacked in one stage, and a total of twelve toilet paper rolls are stored. The expanded opening was closed by heat sealing to create a toilet paper roll package.

However, recently, in order to increase the number of stored toilet paper rolls in one package and to reduce the unit cost of packaging per toilet paper roll, six 1 × 2 toilet paper rolls are provided. It is conceived that three sheets of paper can be stacked to store a total of 18 toilet paper rolls.

[0006] In this case, the upper end portion of the package body has a four-sided overlapped portion when one of the two sides is folded into the other two sides when the conventional 12 toilet paper rolls are stored. The center is divided into five layers including the reinforced plastic film, and the center is reinforced with the reinforced plastic film. Therefore, when 18 sheets of toilet paper roll are stored, the shorter two sides are used. When folded into the inside of the longer two sides, the four sides are overlapped on both sides, and the center is a three-layered part due to the presence of the reinforcing plastic film. Therefore, when the conventional 12 toilet paper rolls are stored, five finger holes are provided in the overlapping portion, but when the 18 toilet paper rolls are stored, the central three paper rolls are provided. Since the handle is weakened relative to the weight of the stored items by being provided in the overlapping portion, the handle may be easily damaged and may not be able to be carried and held.

[0007] Further, as a plastic film used for a package, when storing 12 toilet paper rolls, a thickness of 30 to 32 µm is used, but 18 toilet paper rolls are stored. In this case, it is necessary to use a material with a thickness of 35 μm or more. The most effective way to reduce the cost of the entire package is to reduce the thickness of the plastic film, so we want to make the film as thin as possible. Since the strength is lower, there is a need for a means to compensate for this.

Further, when a package sealed with a plastic film is transported to a place having a low atmospheric pressure at a high temperature or at a high altitude, the package sometimes blisters. For this reason, measures such as making a non-adhesive part in the heat-sealed part of the upper part of the package and perforating holes in the upper part of the package were taken. There was dust and foreign matter entering through the tunnel, and the problem remained.

[0009]

[Problems to be solved by the invention]

 The present invention solves the above-mentioned problems of the prior art, and has a cross section of a substantially square shape in which four 2 × 2 toilet paper rolls are arranged in one stage (in the case of storing 12 toilet paper rolls) or a 2 × 3 in one stage. When the cross section is a substantially rectangular shape in which six toilet paper rolls are arranged (in the case of storage of 18), it has a handle that has sufficient strength even if the film thickness is reduced, and depends on the temperature and pressure. An object of the present invention is to provide a toilet paper roll package that does not generate blisters.

[0010]

[Means for Solving the Problems]

 As a result of various studies to solve the above problems, the present inventors have found that the toilet paper roll has a substantially square cross section in which four 2 × 2 rolls are arranged or a substantially rectangular cross section in which six 2 × 3 rolls are arranged. The opening at the upper end of the approximately square cylindrical plastic film containing the toilet paper roll should be made with one of the two opposite sides inside the other two sides or the shorter two opposite sides longer. A reinforced plastic film is placed on each side of the fold that forms a rectangular shape formed by folding and folding into the inside of the upper part, and the upper heat seal part in the horizontal direction, the lower heat seal part parallel to this, and the upper and lower heat seal parts Two longitudinal heat seal portions in the vertical direction are provided between the frame portions, and the reinforced plastic film is integrally fixed together with the two-fold portion or the four-fold portion of the folded portion, and these four heat seal portions are fixed. One or two finger holes formed by slits are formed in the compartment surrounded by the handle portion, and the handle portion is formed. The present invention was completed by investigating that it is sufficient to provide multiple ventilation holes to prevent the occurrence of blisters caused by temperature and pressure formed by piercing a tapered cone at a position corresponding to .

It is preferable that the finger through hole is reinforced by providing a peripheral reinforcing heat seal portion having a predetermined width around the slit, and a portion where the slit is easily broken is provided at the upper center. In this case, a vertical reinforcing heat seal portion having a predetermined width from the portion to the upper heat seal portion may be provided in parallel with the vertical heat seal portion. In the case of the reinforced mode, the finger hole may be a single large finger hole through which all four fingers except the thumb can pass, and the toilet paper roll may be placed in one step. If two 2 × 3 pieces are arranged side by side, two vertical heat seals in the vertical direction that fix the reinforcing plastic film on each side together are used as reinforcement plates between the upper and lower heat seals. It is also to that investigated the strength to good preferable if provided in parallel at positions six plies, including Kkufirumu.

Reference numeral 3 denotes a handle formed by folding two opposite sides of the opening at the upper end of the package 1 into the other two sides, and reference numeral 4 denotes a folded portion thereof. In the case of a substantially square cross section in which four 2 × 2 pieces are arranged, as shown in FIG. 9, the whole becomes a four-layered section 6 and a substantially rectangular cross section in which six 2 × 3 toilet paper rolls 2 are arranged in one stage. In the case of (1), both ends (each about 1/3 of the whole) become a four-layered part 6 as shown in FIG. 17, and a central part (about one-third of the whole) becomes a two-layered part 7. Reference numeral 5 denotes a reinforcing plastic film which is disposed on both sides of the folded portion 4 one by one. As the reinforcing plastic film 5, a polyethylene film of the same quality as a polyethylene film which is a plastic film which usually constitutes the main body of the package 1 is used. The thickness thereof is larger than the thickness of the plastic film constituting the main body of the package 1.

The present invention is characterized in that two reinforcing plastic films 5 are used, one on each side, in the handle portion 3 at the upper end of the package 1, and the upper end of the cylindrical plastic film in which the folded portion 4 is formed. The reinforcing plastic films 5 and 5 are disposed one by one on both sides of the opening, and the upper heat-sealing portion 8 in the lateral direction for fixing the cylindrical plastic film and the reinforcing plastic films 5 and 5 in the folding portion 4 integrally. A lower heat seal portion 9 is provided in parallel with this, and the four-layer portion 6 or the two-layer portion 7 is located between the upper and lower heat-seal portions 8 and 9 at the position of the four-layer portion 6 or the two-layer portion 7. The two vertical heat seal portions 10 and 10 for fixing the heat sink and the reinforcing plastic films 5 and 5 integrally are provided in parallel with each other. A finger hole 11 formed by a slit is provided in a section surrounded by the rule portions 8, 9, 10, and 10 so that the finger through hole 11 can be easily formed by breaking. The finger through hole 11 is usually formed by a slit of an elliptical line leaving two opposing positions, and a portion of the two positions where a short slit is not formed is broken by a finger. 1, 2, 3, 5, 7, 11, 12, 13, and 15, the middle finger or the index finger has a size enough to pass through, and FIGS. As shown in FIGS. 14 and 16, there is a case where one large finger through hole 11 through which all four fingers except the thumb can pass is provided. In the latter case, it is preferable to provide the hole through the four-layered portion 6. In addition, as shown in FIGS. 7, 8, 15, and 16, a part of the slit which is reinforced by a peripheral reinforcing heat seal portion 11a having a predetermined width provided around the slit or a portion of the finger through hole 11 where the slit is easily broken is provided. 5, 6, 13 and 14, a vertical reinforcing heat seal portion 11b having a predetermined width from the easily broken portion to the upper heat seal portion 8 is provided as shown in FIGS. When provided in parallel with the tapered portions 10, 10, either the four-layered portion 6 or the two-layered portion 7 may be used.

In the present invention, a tapered cone 14 as shown in FIG. 20 is provided at a position corresponding to the inside of the paper tube 12 of the toilet paper roll 2 on the bottom surface of the plastic film constituting the main body of the package 1. It is characterized in that a plurality of ventilation holes 13 for preventing the occurrence of blisters caused by fluctuations in temperature and pressure formed by piercing as shown in FIGS. 18 and 19 are provided. The diameter of the ventilation hole 13 is preferably a minimum size allowing air to enter and exit, and is preferably in a range of 0.1 mm to 1.0 mm. This is because if the diameter is less than 0.1 mm, the speed of air inflow and outflow cannot keep up with the internal and external pressure control, preventing the package from bulging. This is because there is a risk of inhaling.

The reason why the vent hole 13 must be formed by piercing the tapered cone 14 is that, in the case of a hole formed by using a normal punch or the like, the periphery of the hole is formed. Although the shape of the cut outer edge of the hole becomes clear and dust and foreign matter cannot be prevented from entering, the shape of the ventilation hole 13 formed by piercing using a tapered cone 14 is shown in FIG. As shown in FIG. 19, the outer peripheral shape of the hole has a shape in which a plastic film constituting the main body of the packaging body 1 is pushed into the inside and a part thereof is cut off. This is because it stops the intrusion of foreign substances and foreign substances.

The position of the ventilation hole 13 is not preferable on the upper surface or the side surface of the package always exposed to the space, from the viewpoint of preventing intrusion of dust and foreign matter and not impairing the appearance, and as described above. The paper tube of the toilet paper roll 2 on the bottom surface of the plastic film that forms the body of the package 1 so that it functions as a valve every time air enters and exits, and maintains a shape that keeps dust and foreign matter from entering. It is necessary that the position be within 12.

Hereinafter, as an example showing the effect of the present invention, a case of a package accommodating 18 toilet paper rolls will be described together with a comparative example.

[0020]

【Example】

 A cylindrical polyethylene film having a thickness of 30 μm is used as a plastic film constituting the main body of the package, and two polyethylene films having a thickness of 70 μm and a width of 56 mm × a length of 210 mm are used as a reinforcing polyethylene film. The lower part forms a heat seal part with a width of 1 mm and a length of 295 mm (entire width) as a heat seal part, and a vertical heat seal part with a heat seal part of a width of 1 mm and a length of 46 mm, and is surrounded by a heat seal part of 46 mm wide and 180 mm long. The upper and lower two elliptical through-holes have a major axis in the horizontal direction of 25 mm, a minor axis in the vertical direction of 18 mm, and uncut parts of 1 mm and 8 mm above and below the elliptical part. A package was prepared in which a slit was provided at a position where the distance between the heat sealing portion was 12 mm and the distance between the finger holes was 24 mm.

As a comparative example, Comparative Example A: A cylindrical polyethylene film having a thickness of 35 μm was used as a plastic film constituting the main body of the package, and only one reinforcing polyethylene film was used on one side. Comparative Example B: A cylindrical polyethylene film having a thickness of 40 μm is used as a plastic film constituting the main body of the package, and only one reinforced polyethylene film is used on one side. Comparative Example C: A plastic film constituting the main body of the package has a thickness of 30 μm A package was produced in the same manner as in Example except that the cylindrical polyethylene film was used and only one reinforcing polyethylene film was used on one side.

Each of these packages contains 18 toilet paper rolls (approximately 2.8 kg), and each finger is inserted into a finger through hole of the handle and hung, and reciprocating up and down 50 times with a stroke of about 10 cm is repeated. The number of times until the handle portion was broken was measured. Table 1 shows the results.

[0023]

[Table 1]

From the results in Table 1, the thickness of the cylindrical polyethylene film, which is the plastic film constituting the main body of the package, is required to be 35 μm or more in the case of one reinforcing polyethylene film, and even if it is increased to 40 μm. There is no noticeable increase in the effect compared to 35 μm. However, it was found that when the reinforcing polyethylene film was made into two sheets as in the present invention, the improvement effect was remarkable. Even at 30 μm, the effect was sufficient, and a low-cost 30 μm thick polyethylene film could be used.

[0025]

[Effect of the invention]

 As described in detail above, the toilet paper roll package according to the present invention can improve the strength of the handle without greatly changing the conventional manufacturing method and materials, and as a result, the plastic constituting the main body of the package The cost can be reduced by reducing the thickness of the film. In addition, a plurality of ventilation holes to prevent blistering due to temperature and pressure are provided on the bottom of the package to prevent the intrusion of dust and foreign matter, and correspond to the inside of the paper tube of the toilet paper roll. Location, and its shape is maintained at all times, greatly contributing to the stability of the package when transporting at high temperatures or storing and transporting at high altitudes / low pressures, as well as hygiene. . Further, if the finger through hole is reinforced by a reinforcing heat seal portion having a predetermined width provided around the slit, the effect of improving the strength of the handle portion is greater, and thus two small finger through holes are provided. It is also possible to provide a single large finger hole through which all four fingers except the thumb can be passed, instead of using the bicycle handle. It is possible. The practical value of the present invention having such various effects is very large.
