Description

  The present invention relates to a tissue paper storage box.

  Thin paper such as tissue paper is stored in a box made of paper or the like (hereinafter, referred to as a thin paper storage box), and is taken out from an outlet provided in an upper surface portion of the thin paper storage box and used. The conventional thin paper storage box is formed of a rectangular parallelepiped cardboard, and is bulky if discarded as it is after use, so that it can be disassembled after use.

  For example, Patent Document 1 discloses a tissue paper storage box having a pair of upper and lower outer flaps bonded to the outer surfaces of a pair of inner flaps, and a pair of upper and lower outer flaps having a wife surface bonded so that the tips overlap. It has been disclosed. In this configuration, a perforation is provided in the lower outer flap of the pair of upper and lower outer flaps, and an opening is formed in the wife surface by breaking a part of the perforation (arc-shaped perforated line). When a finger is hung on this opening and the wife's face is pulled outward, the remaining perforations (separation perforation lines) are cut, and the bonding between the pair of inner flaps and the upper and outer flaps is released. Further, when the lower and outer flaps are pulled outward from the wife surface, the adhesion between the pair of inner and lower outer flaps is released, and the thin paper storage box can be disassembled.

Japanese Patent No. 4142238

  However, in the conventional disposable thin paper storage box, the perforation for forming the opening must be broken, so that the finger may be hurt. In addition, since there are many bonded portions between the flaps, a strong force is required to peel off these bonded portions during disassembly. Further, since the bonding of the upper and outer flaps and the bonding of the lower and outer flaps are separately released from the pair of inner flaps, the thin paper storage box cannot be dismantled by one operation. Therefore, in the conventional thin paper storage box, it is not easy to disassemble the thin paper storage box.

  An object of the present invention is to provide a tissue paper storage box that can be easily disassembled.

  According to a first aspect of the present invention, there is provided an upper surface side flap having an upper surface provided with an outlet, a bottom surface, a pair of side surfaces, and a pair of wedges, and extending from a side edge of the upper surface. And a bottom flap extending from a side edge of the bottom portion, and a pair of side flaps extending from both side edges of the pair of side portions, respectively, and the wedge portion is disposed on the top surface side. The top side flap, the bottom side flap, and the pair of side flaps are each bent such that the bottom side flap overlaps the inside of the flap and the pair of side flaps overlap the inside of the bottom side flap. And a top paper flap having a pair of joining portions joined to the bottom flap and the pair of side flaps.

  In the first aspect, since the top side flap has a pair of joining portions joined to the bottom side flap and the pair of side flaps, no break perforation is provided. Therefore, there is no need to break the perforation at the time of disassembly, and the burden on the finger can be reduced.

  Further, in the first aspect, since the top side flap is joined to the bottom side flap and the pair of side flaps only by the pair of joints, the number of joints between the flaps is small, and each of the flaps has a small force during disassembly. The flap can be released.

  Furthermore, in the first aspect, only the top side flap is joined to the bottom side flap and the pair of side flaps by the pair of joints, but the bottom side flap and the pair of side flaps are not joined. Good. Therefore, only by pulling out the upper side flap to the outside of the wife surface portion, the joining of the respective flaps is released, and the wife surface portion of the tissue paper storage box can be opened. Therefore, in the first mode, the thin paper storage box can be dismantled by one operation (hereinafter, sometimes referred to as one action).

  In a second aspect according to the present invention, the bottom side flap has a pair of first joined portions to which the pair of joining portions are joined, and the pair of side flaps is joined to the pair of joining portions. A tissue paper storage box having a pair of second joined portions, wherein at least one of the pair of first joined portions and the pair of second joined portions has a cut formed therein.

  In the second aspect, cuts are formed in the pair of first joined portions and / or the pair of second joined portions where the pair of joined portions are joined. In this specification, the cuts include both cuts (e.g., slits) penetrating in the thickness direction of the first and / or second joints and cuts (e.g., half cuts) that do not penetrate in the thickness direction. including.

  With such a configuration, the surface of the bottom flap or the pair of side flaps where the cuts are formed is likely to peel off when the top flap is pulled out of the wife surface. Therefore, in the second aspect, the pair of joints hardly remain on the bottom flap side or the pair of side flap sides during disassembly, and the tissue paper storage box can be disassembled reliably by one operation (one action). .

  A third aspect according to the present invention provides a tissue paper storage box, wherein the cut is a cut (half cut) that does not penetrate in the thickness direction. In the third aspect, the cuts formed in the pair of first bonded portions and / or the pair of second bonded portions do not penetrate in the thickness direction. The bottom flap and / or the pair of side flaps on which the is formed are not easily broken. Thereby, in the third aspect, it is possible to prevent a pair of joints from remaining on the bottom side flap side or the pair of side flap sides by breaking at the bottom side flap side or the pair of side flap sides during disassembly. it can. Therefore, in the third aspect, the thin paper storage box can be more reliably dismantled by one operation (one action).

  In a fourth aspect according to the present invention, the upper surface side flap has a convex portion protruding toward the inside of the wedge surface portion in a joint region of the upper surface side flap provided with the pair of joint portions. To provide a tissue paper storage box. In the fourth aspect, since the upper surface side flap has such a convex portion, the bonding area (bonding region) of the upper surface side flap can be increased. Thereby, at the time of disassembly, the joining portion is likely to remain on the top side flap side, and the joining portion is unlikely to remain on the bottom side flap and the joined portions on the pair of side flaps. Therefore, the thin paper storage box can be disassembled more reliably by one operation (one action).

  According to a fifth aspect of the present invention, there is provided a tissue paper storage box in which an arc-shaped notch is formed at a center of a lower end of the upper side flap. In the fifth aspect, by providing such a notch in the upper flap, a finger can be put on the notch of the upper flap during disassembly. Therefore, the work of pulling out the upper surface side flap to the outside of the wife surface portion is facilitated.

  In a sixth aspect according to the present invention, the bottom side flap includes a projecting portion projecting from an upper end portion of the bottom side flap toward the top surface side so as to face the cutout portion of the top side flap. A tissue paper storage box. In the sixth aspect, the protrusion facing the notch of the upper side flap is provided at the upper end of the bottom side flap, so that the inside of the tissue paper box exposed by the notch of the upper side flap can be shielded.

  In the sixth aspect, by providing such a protrusion, the position of the upper end of the bottom flap is maintained at both ends of the bottom flap near the pair of side flaps. Therefore, the joining position of the upper surface side flap and the bottom surface side flap can be maintained.

  A seventh aspect according to the present invention provides the tissue paper storage box, wherein the projecting portion has both side ends of the projecting portion overlapping the pair of side flaps. In the seventh aspect, the joining position of the upper surface side flap at the bottom surface side flap is determined by overlapping both side end portions of the protrusion protruding from the upper end portion of the bottom surface side flap toward the upper surface side with the pair of side surface side flaps. It can be on both ends of the protrusion. Therefore, positioning of the joining position on the bottom flap is easy.

  Further, in the seventh aspect, the projecting portion of the bottom side flap overlaps with the pair of side flaps, so that the top side flap is joined to the bottom side flap and the pair of side flaps, and both end portions of the projecting portion are formed. The portion is locked between the top side flap and the pair of side flaps. This increases the locking area of the bottom side flap between the top side flap and the pair of side flaps, thereby preventing a decrease in the bonding strength between the top side flap and the bottom side flap and / or the pair of side flaps. be able to.

  An eighth aspect according to the present invention provides a tissue paper storage box, wherein the upper surface side flap has a pair of reinforcing portions joined to the pair of side surface side flaps near the upper surface portion of the upper surface side flap. In the eighth aspect, a pair of reinforcing portions that are joined to the upper surface side flap and the pair of side surface side flaps are formed on the upper surface side flap separately from the pair of joined portions. For this reason, it is possible to prevent a decrease in the bonding force between the top side flap, the bottom side flap, and the pair of side flaps.

  Further, in the eighth aspect, since the pair of reinforcing portions is provided near the upper surface portion of the upper surface side flap, the distance from the side edge of the upper surface portion along the height direction of the tissue paper storage box to the pair of reinforcing portions. In contrast, the distance from the lower end of the upper side flap to the pair of reinforcing portions is longer. Therefore, when the upper side flap is pulled out of the wife surface part at the time of disassembly, after the joining of each flap at the pair of joints is released, the upper side flap and the pair of side flaps at the pair of reinforcing parts are further released. Can be performed with less force.

  According to one embodiment of the present invention, a tissue paper storage box that can be easily disassembled can be provided.

Thereby, the inside of the thin paper storage box 100 which may be exposed by the cutout portion 11b of the upper side flap 11 can be shielded. Therefore, the protrusion 21 b can prevent the notch 11 b of the upper side flap 11 from being exposed.

  Further, in the tissue paper storage box 100 of the first embodiment, by providing such a protruding portion 21b, the both ends 21c of the bottom flap 21 near the pair of side flaps 31 are located at the upper end 21a of the bottom flap 21. Position is maintained. That is, even if the protrusion 21b is provided on the upper end 21a of the bottom side flap 21, a step is generated between the both ends SE and the upper end 21a of the protrusion 21b, and the bottom side flap 21 Does not change the position of the upper end 21a. Therefore, the joining position (joined part 70) between the top side flap 11 and the bottom side flap 21 can be maintained (see FIG. 4).

  Further, in the tissue paper storage box 100 of the first embodiment, both end portions SE of the protruding portion 21 b protruding from the upper end portion 21 a of the bottom side flap 21 toward the upper surface portion 10 overlap with the pair of side flaps 31. . Thereby, the joining position of the upper surface side flap 11 on the lower surface side flap 21 can be set to both end portions SE of the protruding portion 21b. Therefore, the positioning of the joint position of the upper surface side flap 11 on the lower surface side flap 21 is easy.

  Further, in the tissue paper storage box 100 of the first embodiment, the protrusion 21b of the bottom side flap 21 overlaps with the pair of side flaps 31, so that the top side flap 11 is connected to the bottom side flap 21 and the pair of side flaps 31. In the joined state, both end portions SE of the protruding portion 21b are locked between the upper surface side flap 11 and the pair of side surface side flaps 31. As a result, the locking area of the bottom side flap 21 between the top side flap 11 and the pair of side flaps 31 increases, so that the top side flap 11 and the bottom side flap 21 and / or the pair of side flaps 31 It is possible to prevent a decrease in bonding force.

  FIG. 7 is an expanded view of a part (upper side flap) of the end face of the thin paper storage box according to the second embodiment. In the tissue paper storage box 100 of the second embodiment, as described above, the bottom side flap 21 has a pair of first joined portions 71 (70) to which a pair of joining portions 60 are joined, and a pair of side flaps. 31 has a pair of 2nd to-be-joined parts 72 (70) which a pair of joining part 60 joins. The cuts 80 are formed only in the pair of first joined portions 71 of the pair of first joined portions 71 and the pair of second joined portions 72.

  Here, the cut 80 may be a cut (for example, a slit) penetrating in the thickness direction (X direction) or a cut (half cut or the like) not penetrating in the thickness direction (X direction). In the tissue paper storage box 100 of the second embodiment, the cut 80 is formed by a half cut. That is, in the tissue paper storage box 100 of the second embodiment, the cut 80 does not penetrate in the thickness direction (X direction) of the pair of first joined portions 71 (70).

  The shape of the cut (half cut) is not particularly limited. For example, in the second embodiment, as shown in FIG. 7, a plurality of grid-like half cuts are formed. The depth of the cut (half cut) is not particularly limited, but is preferably 0.01 to 0.5 mm, more preferably 0.03 to 0.4 mm, in the thickness direction of the bottom side flap 21. Preferably it is 0.05 to 0.3 mm.

  In the tissue paper storage box 100 of the second embodiment, a cut 80 is formed in the pair of first joined portions 71 (70) of the bottom flap 21 to which the pair of joining portions 60 are joined. Thereby, when pulling out the upper surface side flap 11, the surfaces of the pair of first joined portions 71 in the bottom side flap 21 where the cuts 80 are formed are easily peeled off. Therefore, in the second embodiment, the pair of joints 60 are unlikely to remain on the entire joined portion 70 of the bottom side flap 21 and the pair of side flaps 31 during disassembly, and the tissue paper storage can be securely performed by one operation (one action). The box 100 can be dismantled.

  Further, in the tissue paper storage box 100 of the second embodiment, the cuts 80 formed in the pair of first joined portions 71 (70) do not penetrate in the thickness direction (X direction). Upon release, the bottom flap 21 in which the cut 80 is formed is not easily broken. Thus, in the second embodiment, it is possible to prevent the joint portion 60 from remaining on the bottom side flap 21 side due to the bottom side flap 21 side or the pair of side side side flaps 31 breaking during disassembly. Therefore, in the second embodiment, the thin paper storage box 100 can be disassembled more reliably by one operation (one action).

  FIG. 8 is an expanded view of a part (upper side flap) of the end face of the thin paper storage box according to the third embodiment. In the tissue paper storage box 100 of the third embodiment, a half cut notch 80 is formed in the pair of second joined portions 72 (70) of the pair of side flaps 31 to which the pair of joining portions 60 are joined.

  Thereby, in the tissue paper storage box 100 of the third embodiment, when the upper surface side flap 11 is pulled out at the pair of second joined portions 72 (70) of the pair of side surface side flaps 31 in which the cuts 80 are formed. Is easily peeled off. Therefore, in the third embodiment, a part of the joint portion 60 is less likely to remain on the side flap 31 side during disassembly, and as a result, the joint portion is formed on the entire joint 70 between the bottom side flap 21 and the pair of side flaps 31. 60 is hard to remain. Therefore, the thin paper storage box 100 can be reliably disassembled by one operation (one action).

  FIG. 9 is an expanded view of a part (upper side flap) of the end face portion of the thin paper storage box according to the fourth embodiment. In the tissue paper storage box 100 of the fourth embodiment, the cuts 80 formed in the pair of second joined portions 72 (70) in the pair of side flaps 31 are formed by a plurality of V-shaped half cuts. .

  Even when the cut 80 formed by such a V-shaped half cut is provided in the pair of second joined portions 72 in the side flap 31, the surface is easily peeled when the upper flap 11 is pulled out. Become. Therefore, regardless of the shape of the cut 80, the paired joints 60 are unlikely to remain on the entire jointed portion 70 of the bottom side flap 21 and the pair of side flaps 31 during disassembly, so that one operation (one action) is ensured. The thin paper storage box 100 can be dismantled.

  FIG. 10 is an expanded view of a part (upper side flap) of the end face portion of the tissue paper storage box according to the fifth embodiment. In the tissue paper storage box 100 of the fifth embodiment, cuts 80 are formed in the pair of first joined portions 71 (70) of the bottom side flap 21 and the pair of second joined portions 72 (70) of the pair of side flaps 31. Are formed.

  Thereby, in the tissue paper storage box 100 of the fifth embodiment, when the upper side flap 11 is pulled out, the pair of first joined portions 71 (70) and the pair of second joined portions 72 (70) each having the cut 80 are formed. In any of 70), the surface is easily peeled off. That is, the entire surface of the joined portion 70 of the bottom side flap 21 and the pair of side flaps 31 is easily peeled off. Therefore, in the fifth embodiment, at the time of disassembly, the joining portion 60 hardly remains in the entire joined portion 70 between the bottom flap 21 and the pair of side flaps 31. Therefore, the thin paper storage box 100 can be disassembled more reliably by one operation (one action).

  FIG. 11 is an expanded view of a part (upper side flap) of the end face portion of the tissue paper storage box according to the sixth embodiment. In the tissue paper storage box 100 of the sixth embodiment, the upper surface side flap 11 has the convex portion 90 that is convex toward the inside of the wife surface portion 40. Specifically, the convex portion 90 of the top side flap 11 has a shape that is convex with respect to the bottom side flap 21 and the pair of side flaps 31.

  The convex portion 90 is formed in a convex shape on the upper surface side flap 11 by pressing the upper surface side flap 11 by press working or the like. The height of the convex portion 90 is not particularly limited, but is preferably 0.05 to 1.0 mm in the thickness direction of the upper surface side flap 11 from the surface on which the convex portion 90 is formed on the upper surface side flap 11, and more preferably 0 mm. 0.07 to 0.7 mm, and more preferably 0.1 to 0.5 mm. Here, the height of the protrusion 90 is a distance from the surface of the upper surface side flap 11 where the protrusion 90 is formed to the top of the protrusion 90 along the thickness direction of the upper surface side flap 11.

  Further, in the tissue paper storage box 100 of the sixth embodiment, the convex portion 90 of the upper side flap 11 is formed in the joint area 11c of the upper side flap 11 where the pair of joints 60 are provided. That is, the top side flap 11 is joined to the bottom side flap 21 and the pair of side flaps 31 via the projection 90. Due to the presence of such a convex portion 90, the bonding area between the bonding region 11c of the upper surface side flap 11 and the bonded portions 70 on the bottom surface side flap 21 and the pair of side surface side flaps 31 increases.

  In the sixth embodiment, since the upper surface side flap 11 has such a convex portion 90, the joining area (joining region 11c) of the upper surface side flap 11 can be increased. Accordingly, when the tissue paper storage box 100 is disassembled, the joining portion 60 is likely to remain on the upper flap 11 side. That is, the joining portion 60 hardly remains in the joined portion 70 on the side of the bottom side flap 21 and the pair of side flaps 31. Therefore, the thin paper storage box 100 can be disassembled more reliably by one operation (one action).

  FIG. 12 is an expanded view of a part (upper side flap) of the end face portion of the tissue paper storage box according to the seventh embodiment. In the tissue paper storage box 100 of the seventh embodiment, the upper side flap 11 further has a pair of reinforcing portions 62. The pair of reinforcing portions 62 are formed near the upper surface portion 10 of the upper surface side flap 11, and are joined to the upper surface side flap 11 and the pair of side surface side flaps 31.

  The material of the reinforcing portion 62 is not particularly limited. For example, an adhesive of a material (epoxy resin or the like) applicable to the above-described joining portion 60 can be used. The method of forming the reinforcing portion 62 is not particularly limited. For example, the reinforcing portion 62 can be formed by a bonding method (hot melt or the like) applicable to the above-described bonding portion 60.

  In the tissue paper storage box 100 of the seventh embodiment, a pair of reinforcing portions 62 that join the upper surface side flap 11 and the pair of side surface side flaps 31 are formed on the upper surface side flap 11 separately from the pair of joining portions 60. I have. Therefore, the joining of the upper surface side flap 11 and the bottom surface side flap 21 and the pair of side surface flaps 31 by the pair of joining portions 60 can be reinforced. Thereby, it is possible to prevent a decrease in the bonding force between the upper surface side flap 11 and the bottom surface side flap 21 and the pair of side surface side flaps 31.

  Further, in the seventh embodiment, since the pair of reinforcing portions 62 are provided near the upper surface portion 10 of the upper surface side flap 11, the reinforcing portions 62 extend from the side edge 10 a of the upper surface portion 10 along the height direction of the tissue paper storage box 100. The distance from the lower end 11 a of the upper surface side flap 11 to the pair of reinforcing portions 62 is longer than the distance to the pair of reinforcing portions 62. Therefore, when the upper surface side flap 11 is pulled out at the time of disassembly, after the bonding of each flap at the pair of bonding portions 60 is released, the bonding of the upper surface side flap 11 and the pair of side surface flaps 31 at the pair of reinforcing portions 62 is further performed. Release can be performed with a small force.

  Hereinafter, the present invention will be specifically described with reference to examples. The measurement and evaluation of Examples and Comparative Examples were performed by the following tests.

The durability was evaluated as ○ (good) when the flap was not peeled off, and x (poor) when the flap was peeled off.

<Breaking strength>
The breaking strength of the thin paper storage box 100 (carton) was measured. Specifically, a push-pull gauge (manufactured by IMADA, trade name "Digital Force Gauge Z2-20N") is fixed to a vertical power measurement stand (model MX-500N, manufactured by IMADA). Attach it to the push-pull gauge so that the key-like tip of the standard key attachment (A-1, width 12 mm, small hook) faces the left side toward the measurement value display surface. A double clip (narrow width 13 mm, depth 7 mm) is attached to the center of the finger hook FP (notch 11b) of the upper side flap 11 of the carton to be measured. A stand with a height of 115 mm is placed on the measuring stand, and a carton with a double clip is placed thereon. Attach the key-shaped tip of the push-pull gauge to the outside of the carton of the two knobs of the double clip. Lower the push-pull gauge until the bottom of the carton is in horizontal contact with the measuring stand, and fix the position 5 mm inward from the flap with the double clip with your palm. Turn on the power of the push-pull gauge, press the "PEAK" button, and measure the highest breaking strength when pulled. Press the "ZERO" button on the push-pull gauge, check that the display is 0, and move the measuring stand up until the flap is opened. Then, the value displayed on the push-pull gauge is read. The measurement of the breaking strength was performed six times, and the average value was defined as the breaking strength (kgf). When the breaking strength was 2.1 kgf or less, the dismantling of the tissue paper storage box 100 was evaluated as easy, and when the breaking strength exceeded 2.1 kgf, the dismantling of the tissue paper storage box 100 was evaluated as difficult.

<Dismantling>
The disassembly of the thin paper storage box 100 (carton) was confirmed. Specifically, when the carton was dismantled, it was confirmed whether or not the carton was dismantled by one operation (one action). The disassembly was confirmed six times, and the percentage (%) of disassembly by one operation (one action) was quantified as follows. The disassembly was evaluated based on the following criteria. When the evaluation was 3 or more, the disassembly was good, and when the evaluation was less than 3, the disassembly was poor.
10%
2 Less than 30% (excluding 0%)
3 30% or more and less than 60% 4 60% or more and less than 80% 5 80% or more and less than 90% 6 90% or more
