Description

  The present invention relates to a kitchen paper roll package in which a plurality of kitchen paper rolls are gusset-wrapped with a packaging film.

  About 4 to 6 kitchen paper rolls obtained by winding a strip of kitchen paper in a roll shape are marketed in a state where a plurality of kitchen paper rolls are collectively enclosed in a gusset packaging bag. In particular, there are many cases where four kitchen paper rolls are gusset-wrapped together with their body surfaces attached together.

  In such a kitchen paper roll package, when using the kitchen paper roll, the user breaks the gusset packaging bag and takes out the individual kitchen paper roll contained therein.

  By the way, the kitchen paper roll is formed by winding a certain length of kitchen paper into a cylindrical shape, so that it takes a certain period of time to fully use one. Therefore, in the kitchen paper roll packaged body marketed in a plural number, some kitchen paper rolls must be stored even after breaking and opening the gusset packaging bag for a long time.

  On the other hand, kitchen paper rolls are often used in situations where food materials are handled, such as a kitchen in the home, and therefore are required to be hygienic.

  However, in the conventional kitchen paper roll package, the user opens the remaining kitchen paper roll that is not used, such as an excessively large opening opening, such as the user tearing the gusset packaging bag open. When stored in the gusset packaging bag after the opening, there is a possibility that dust, dust, insects and the like may invade from the opening, and there is anxiety in terms of hygiene during the storage period.

  In addition, some conventional kitchen paper roll packages have improved perforation by forming perforation lines and cuts for opening, but it is possible to form an opening that allows easy removal of the kitchen paper roll. There was no one that could be opened and that could be easily closed without gaps after the opening was formed.

A lower melting point is preferable because it can be fused at a low temperature. However, if the melting point is excessively low, the packaging bag may be scratched or punctured due to friction or the like. 80 ° C. Examples of the polyethylene resin film include linear low density polyethylene film (LLDPE), low density polyethylene film (LDPE), and 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 and cost. Suitable.

  The kitchen paper roll package 1 according to this embodiment in which the kitchen paper roll group 30... Is included in the gusset packaging bag 2 is, for example, a packaging film formed in a cylindrical shape in advance, with both side portions thereof. In the state of being pushed into the cylinder, the one opening is sealed by heat fusion processing or the like, and the handle portion 20 is formed to form a precursor of a three-sided closed gusset packaging bag, and then packaged It can manufacture by inserting in the precursor in the state which arranged the kitchen paper roll 20 which is a thing, and sealing the other opening part by heat-sealing after that. The heat fusion treatment can be performed at 180 to 230 ° C. according to a general method. An opening perforation line 50 according to the present embodiment, which will be described later, can be formed simultaneously with the formation of the handle portion 20 or after the formation of the handle portion 20 and before the kitchen paper rolls 30 are inserted.

  On the other hand, the grip portion 20 according to the gusset packaging bag 2 according to the present embodiment has a linear heat fusion portion in the width direction in the vicinity of the upper end, in addition to the fusion portion 41 that is a boundary with the bag body portion 10. 42 is formed, and a pair of finger cut hole cut portions 21 and 21 are formed between the upper and lower heat fusion processing portions 41 and 42. Thus, by forming the heat-sealing parts 41 and 42 in the upper and lower sides and forming the finger hooking holes 21 and 21 between them, the packaging films laminated in the handle part 20 are not misaligned, and the handle part 20 is easily handled. Has been improved.

  Further, in the kitchen paper roll package 1 according to the present embodiment, a reinforcing film sheet 25 is laminated and fused to reinforce the handle portion 20, particularly in the vicinity of the notch portions 21 and 21 for the finger hooking holes. . By providing the reinforcing film sheet 25 on the handle portion 20 in this manner, the thickness of the handle portion 20 is increased, and the fingers when the fingers are held in the finger-holding holes formed by the notch portions 21 and 21 for the finger-holding holes are held. The burden on is reduced. In the form shown in the figure, vertical heat-sealing parts 43, 43 surrounding the notch parts 21, 21 for finger hooking holes are formed together with the upper and lower heat-sealing parts 41, 42, and the kitchen paper roll packaging according to this embodiment is formed. The body 1 is integrally laminated and fused with the reinforcing film sheet 25 to the handle portion 20 by the heat fusion portions 41, 42, and 43. However, the fusion mode of the reinforcing film sheet 25 is not limited to this mode. The reinforcing film sheet 25 is preferably a polyethylene film having a melting point of 110 to 120 ° C. and 50 to 70 μm. When this polyethylene film is used, it is possible to easily perform fusion-bonding by heat-sealing, and it is possible to improve the unsealing property even when a perforation line for opening is provided.

  On the other hand, in the kitchen paper roll package 1 of the present embodiment, as is understood from FIG. 1, the gusset packaging bag 2 is characteristically one side edge in the width direction in a state where the side portions 2A and 2B are folded. An opening perforation line 50 extending obliquely downward from 2a toward the other side edge 2b is provided. The unsealing perforation line 50 is provided so as to penetrate from the surface that becomes the front surface 13 to the one side portion 2A that is folded and the surface that becomes the back surface 14. Therefore, in the state where the kitchen paper rolls 30 are packaged, as shown in FIGS. 3 to 5, there is a single opening perforation line 50 that extends from one gusset portion 11 </ b> A to the front surface 13 and the back surface 14. It has been formed.

  In the illustrated embodiment, the surface of the opening perforation line 50 that faces the other side 2B is a surface that forms the front surface 13 and the back surface 14 so that the opening perforation line 50 does not penetrate the other side 2B. In this embodiment, the opening perforation line 50 may be formed so as to penetrate the other side portion 2B. In this case, a perforation line that is not continuous with the front surface 13 and the back surface 14 is formed in the other gusset portion 11B. However, there is no problem even if such a perforation line is arranged.

  On the other hand, the opening perforation line 50 according to the present embodiment is such that the base end 50S on the one side edge 2a side of the opening perforation line 50 in the state where the side portions 2A and 2B of the gusset packaging bag 2 are folded is kitchen paper. In a state in which the roll group 30 is packaged, it is located between the part located on the upper end surface of the kitchen paper roll group 30 and the lower edge 20B of the handle portion 20. That is, the portion formed in one gusset portion 11A of the opening perforation line 50 is between the portion X located on the upper end face of the kitchen paper roll group 30 and the grip portion lower edge 20B, and the gusset portion 11A. The portions 50b and 50c formed on the front surface 13 and the back surface 14 are continuously formed from both ends of the portion 50a formed on the front surface, and the portions 50b and 50c formed on the front surface 13 and the back surface 14 are formed from the gusset portion 11A. It is arranged linearly so as to incline downward toward the other gusset portion 11B on the opposite side.

  In the kitchen paper roll package 1 according to the present embodiment, the opening perforation line 50b that is continuous with the front surface 13 and the back surface 14 of the handle portion 20 is arranged according to the disposition form of the opening perforation line 50. By pulling upward the portion close to the gusset portion 11A, it is possible to easily remove the enclosed kitchen paper roll starting from a position P between the gusset portion 11A and the front surface 13 and the back surface 14 of the opening perforation line 50. An opening for extraction can be formed.

  Further, the opening perforation line 50 according to the present embodiment packages the base end 50S of the one side edge 2a in the width direction when the side portions 2A and 2B are folded and the kitchen paper roll group 30. The length L1 between the kitchen paper rolls 30 included in the kitchen paper rolls 30 included in the kitchen paper rolls 30 is set to a length that exceeds the radius 30R of the kitchen paper rolls 30 included. When the opening perforation line 50 is formed in this way, the opening perforation line 50 is cleaved to form an opening, and after removing a part of the contained kitchen paper roll 30, for example, one, it is shown in FIG. As described above, the lower portion 11x divided by the tearing of the opening perforation line 50, that is, a part of the portion where the handle portion 20 is not a trap is covered with the end face of the remaining kitchen paper roll 30 in the paper tube. Can be pushed into. And the part 11y by the side of the handle part 20 divided | segmented with it can be made to cover the kitchen paper roll which coat | covered the end surface like a cover. If it does in this way, opening will be sealed and it will prevent that dust, dust, an insect, etc. enter into the bag after opening.

  As described above, in the kitchen paper roll package 1 according to this embodiment, an opening through which the contained kitchen paper roll 30 can be taken out can be easily formed, and the opening can be easily and reliably closed.

  Here, as for the perforation line for opening which concerns on this embodiment, each length L2 of the width direction of the gusset packaging bag 2 of the parts 50b and 50c formed in the front surface 13 and the back surface 14 is the diameter 30D of the kitchen paper roll 30. It is desirable that the length exceeds. With this length, when the opening perforation line is cleaved due to the structure of the gusset packaging bag 2, an opening slightly larger than the end faces of two adjacent kitchen paper rolls is formed, and the internal kitchen paper roll 30 Can be taken out very easily.

  Furthermore, the more preferable form in the opening perforation line 50 according to the present embodiment is that the end 50E of the opening perforation line 50 is between the center in the width direction of the gusset packaging bag 2 and the other side edge 2b as shown in the figure. The length L3 between the other side edge 2b and the terminal end 50S is longer than the length of the radius 30R of the kitchen roll paper 30. If the kitchen paper roll group 30 is packaged, the other gusset 11B of the portions 50b and 50c on the front surface 13 and the back surface 14 of the opening perforation line 50 and the other gusset portion 11B and the front surface 13 or a length between the boundary with the back surface 14 is a length equal to or longer than the radius 30R of the kitchen roll paper 30. If it does in this way, while opening of the wide mouth which is easy to take out the kitchen paper roll 30 will be formed, it can be closed without gap when the opening is closed as described above. In other words, when the length L3 between the terminal end 50E of the opening perforation line 50 and the other side edge 2b is less than the length of the radius 30R of the kitchen roll paper 30, when the opening is closed, the gap Is likely to occur. In addition, about the height direction position of this termination | terminus 50E, as shown in FIGS. 1-5, it may exist in the position above the site | part X located in the upper side end surface of the kitchen paper roll group 30 ..., as shown in FIG. May be in the lower position.

  On the other hand, in the kitchen paper roll package 1 according to the present embodiment, as shown in FIG. 1, the opening perforation line 50 extends downward at an angle α of more than 45 ° and less than 90 ° with respect to the vertical direction. It is desirable. When the opening perforation line 50 is provided in this way, when the handle portion 20 is held, the handle portion 20 is easily pulled and opened, and when the handle portion 20 is carried, the unintended breakage is difficult.

  In addition, the length of the cut portion and the tie portion of the opening perforation line 50 and the ratio thereof in the present embodiment are desirably in the range of (cut portion: tie portion) = 1 mm: 1 mm to 6 mm: 6 mm. Within this range, the opening perforation line 50 can be easily cleaved and unintentional cleaving can be prevented.

  In the kitchen paper roll package 1 according to the above-described embodiment, by opening the perforation line 50 for opening, it is possible to easily form an opening through which the contained kitchen paper roll 30 can be easily taken out, and the kitchen. After taking out the paper roll, the lower part 11x divided by the tearing of the opening perforation line 50 can be pushed into the paper tube while covering the upper end surface of the remaining kitchen paper roll, and the upper part 11y thus cut off. Can be sealed easily and without a gap.
