Description

本発明は、ティシュペーパーを収納する収納箱に関し、詳しくは、ティシュペーパーを積層した積層体を収納する収納箱に関する。 TECHNICAL FIELD The present invention relates to a storage box for storing tissue paper, and more particularly to a storage box for storing a laminated body in which tissue papers are stacked.

従来、積層されたティシュペーパーを収納しそれらを分離して使用に供するとともに、それらが使い尽くされたときには、ユーザが、替えの積層ティシュペーパーを再収納して使用に供する収納箱が提供されている。 Conventionally, a storage box is provided that stores stacked tissue papers and separates them for use, and when they are exhausted, a user can re-store replacement stacked tissue papers for use. There is.

特許文献１では、ティシュペーパーを収納箱に収納して収納箱の側面を閉める際、ティシュペーパーの積層体に収納箱の側面に備えられたフラップを差し込んでしまうのを防ぐために、収納箱の底面にフラップの挿入を案内するシートを設けることが記載されている。 In Patent Document 1, when the tissue paper is stored in the storage box and the side surface of the storage box is closed, in order to prevent the flap provided on the side surface of the storage box from being inserted into the stack of tissue paper, the bottom surface of the storage box is prevented. It is described that a sheet for guiding the insertion of the flap is provided in the.

特開２００５−５３５３４号公報JP, 2005-53534, A

ユーザがティシュペーパーの詰め替えをする収納箱の構成では、特許文献１のように底面にシートが設けられる場合、シートがティシュペーパーを収納箱に入れる際の抵抗となることがある。すなわち、収納箱の底面とシートの間に一部のティシュペーパーが入り込んでしまい、ユーザがティシュペーパーの積層体を収納箱へ収納し辛い場合がある。また、収納箱の内側の表面が粗い場合、これがティシュペーパーを収納箱に入れる際の抵抗となることもある。すなわち、積層体が収納箱の側面などに接触することで積層体と収納箱との間で強い摩擦力が発生することがあり、これによってユーザが入れにくいと感じることがある。 In the configuration of the storage box in which the user refills the tissue paper, when the sheet is provided on the bottom surface as in Patent Document 1, the sheet may become a resistance when the tissue paper is put into the storage box. That is, a part of the tissue paper may enter between the bottom surface of the storage box and the sheet, and it may be difficult for the user to store the stack of tissue papers in the storage box. Further, if the inner surface of the storage box is rough, this may become a resistance when the tissue paper is put into the storage box. That is, a strong frictional force may be generated between the stacked body and the storage box due to the stacked body coming into contact with the side surface of the storage box or the like, which may make it difficult for the user to enter.

よって、本発明の目的は、詰め替え用のティシュペーパーの積層体を収納箱に入れるときの抵抗が低減された収納箱を提供することにある。 Therefore, an object of the present invention is to provide a storage box with reduced resistance when the refilled tissue paper laminate is put into the storage box.

Portions 2b, 3b, 4b are formed. The present invention is not limited to this, and the coating portion may be formed on at least a part of the inner surface of the storage box 10.

図３は、本発明の第１実施形態の変形例に係る収納箱を示す図であって、図１の収納箱の展開シートを示す下面図である。展開シート１０ｂにおいて、本実施形態の収納箱１０の天面１、底面２、第１長側面３、第２長側面４の各内側には、各面の一方の短手方向側辺からもう一方の短手方向側辺に亘って、所定の幅、かつ、所定の間隔でコート剤を塗布することによって、それぞれ、塗布部１ｂ、１ｃ、２ｂ、３ｂ、４ｂが形成される。特に、天面１については、一対の塗布部１ｂは、天面１の短手方向側辺から後述する取出し口１１の短手方向側辺に亘って形成される。また、一対の塗布部１ｃは、天面１の短手方向側辺からもう一方の短手方向側辺に亘っており、取出し口１１の長手方向側辺に沿うように形成される。本発明は、塗布部として、各面の全面や所定の幅かつ所定の間隔に形成したが、これに限らず、後述する各短側面の内側や内フラップにも形成してもよい。また、塗布部は、デザイン性があるように形成してもよい。塗布方法については、公知のものを採用できる。 FIG. 3 is a view showing a storage box according to a modified example of the first embodiment of the present invention, and is a bottom view showing a developed sheet of the storage box in FIG. 1. In the unfolding sheet 10b, inside each of the top surface 1, the bottom surface 2, the first long side surface 3, and the second long side surface 4 of the storage box 10 of the present embodiment, one side from one lateral direction side of each surface to the other side. The coating portions 1b, 1c, 2b, 3b, and 4b are respectively formed by coating the coating agent with a predetermined width and a predetermined interval over the lateral side of the. In particular, with respect to the top surface 1, the pair of coating portions 1b are formed from the lateral sides of the top surface 1 to the lateral sides of the outlet 11 described later. The pair of coating portions 1c extends from the lateral side of the top surface 1 to the other lateral side thereof, and is formed along the longitudinal side of the ejection port 11. In the present invention, the application portion is formed on the entire surface of each surface or with a predetermined width and a predetermined interval, but the application portion is not limited to this, and may be formed on the inner side of each short side surface or the inner flap described later. Further, the application part may be formed so as to have a design. As a coating method, a known method can be adopted.

そして、天面１の短手方向側辺につながる第１短側面５と、第１短側面５と対向するように天面１の短手方向側辺につながる第２短側面５と、第１長側面３の短手方向側辺につながる内フラップ６と、第２長側面４の短手方向側辺につながる内フラップ７とによって、短手方向の各面を形成している。さらに、第１短側面５の短手方向側辺につながる天面１の短手方向側辺と対向する側辺からタブ１５が延出している。そして、第１長側面３、天面１、第２長側面４、底面２、糊しろ８のそれぞれの境界には、折り曲げるための折り曲げ線が形成されている。第１長側面３と天面１との境界には、第１折り曲げ線Ｌ１が形成されている。そして、天面１と第２長側面４との境界には、第２折り曲げ線Ｌ２が形成されている。また、第２長側面４と底面２との境界には、第３折り曲げ線Ｌ３が形成されている。さらに、底面２と糊しろ８との境界には、第４折り曲げ線Ｌ４が形成されている。したがって、各面を折り返し、貼り合せることで収納箱１０を形成している。 Then, a first short side surface 5 connected to the lateral side of the top surface 1, a second short side surface 5 connected to the lateral side of the top surface 1 so as to face the first short side surface 5, and a first The inner flap 6 connected to the lateral side of the long side surface 3 and the inner flap 7 connected to the lateral side of the second long side surface 4 form each surface in the lateral direction. Furthermore, the tab 15 extends from the side opposite to the lateral side of the top surface 1 connected to the lateral side of the first short side surface 5. A fold line for bending is formed at each boundary of the first long side surface 3, the top surface 1, the second long side surface 4, the bottom surface 2, and the adhesive margin 8. A first fold line L1 is formed at the boundary between the first long side surface 3 and the top surface 1. A second bending line L2 is formed at the boundary between the top surface 1 and the second long side surface 4. Further, a third bending line L3 is formed at the boundary between the second long side surface 4 and the bottom surface 2. Further, a fourth bending line L4 is formed at the boundary between the bottom surface 2 and the margin 8. Therefore, the storage box 10 is formed by folding back and pasting each surface.

また、収納箱１０の天面１の中央には、収納箱１０に収納されているティシュペーパーＰを取り出すための取出し口１１を形成するミシン目１１ａが設けられており、天面１の内側にプラスチック製のフィルム１２が貼付されている。フィルム１２によって、ホコリ等が収納箱１０に侵入しないように閉塞されている。さらに、フィルム１２には、取出し口１１の長手方向に沿ってスリット１２ａが形成されており、このスリット１２ａを介してティシュペーパーＰを取り出すことができる。 Further, at the center of the top surface 1 of the storage box 10, there is provided a perforation 11a forming an outlet 11 for taking out the tissue paper P stored in the storage box 10, and inside the top surface 1. A plastic film 12 is attached. The film 12 blocks the dust and the like from entering the storage box 10. Further, a slit 12a is formed in the film 12 along the longitudinal direction of the take-out port 11, and the tissue paper P can be taken out through the slit 12a.

さらに、本実施形態の収納箱１０は、内フラップ６及び７を内側に折り曲げ、内フラップ６及び７と底面２とからなる空間に、タブ１５を押し込むことで第１短側面５および第２短側面５を形成している。天面１と第１短側面５および第２短側面５と接続されているため、天面１から底面２の方向に対して強度を保つことができる。また、本実施形態の収納箱１０は、上述したように、タブ１５を押し込むことで第１短側面５及び第２短側面５を形成しているため、押し込んだタブ１５を引き抜き、第１短側面５および第２短側面５、内フラップ６及び７を外側に折り返すことで開口状態となり、新たな積層体２０を挿入することができる。 Further, in the storage box 10 of the present embodiment, the inner flaps 6 and 7 are bent inward, and the tabs 15 are pushed into the space formed by the inner flaps 6 and 7 and the bottom surface 2, whereby the first short side surface 5 and the second short side surface 5 are formed. The side surface 5 is formed. Since the top surface 1 is connected to the first short side surface 5 and the second short side surface 5, the strength can be maintained in the direction from the top surface 1 to the bottom surface 2. Further, as described above, the storage box 10 of the present embodiment forms the first short side surface 5 and the second short side surface 5 by pushing the tab 15, so that the pushed tab 15 is pulled out and the first short side surface 5 is pulled out. The side surface 5, the second short side surface 5, and the inner flaps 6 and 7 are folded back to be in an open state, and a new laminated body 20 can be inserted.

本実施形態の収納箱１０の素材となる原紙としては、例えば、古紙パルプ等の各種のパルプを原料とする公知の紙素材などである。そして、本実施形態の収納箱１０に用いる原紙の坪量は、２５０ｇ／ｍ2以上、４５０ｇ／ｍ2以下である。また、原紙の厚みは、３００μｍ以上、６００μｍ以下である。原紙の厚みが３００μｍ未満であると、耐久性が低下し、すぐに収納箱にした時に潰れやすくなってしまう。また、原紙の厚みが６００μｍを超えると収納箱との耐久性には優れるが、厚みが増加することで収納箱を形成する際に折りにくくなってしまう。 The base paper used as the material of the storage box 10 of the present embodiment is, for example, a known paper material made of various pulps such as waste paper pulp. The basis weight of the base paper used in the storage box 10 of this embodiment is 250 g/m 2 or more and 450 g/m 2 or less. The thickness of the base paper is 300 μm or more and 600 μm or less. When the thickness of the base paper is less than 300 μm, the durability is lowered, and the base paper is likely to be crushed when immediately put into a storage box. Further, if the thickness of the base paper exceeds 600 μm, the durability with the storage box is excellent, but the increased thickness makes it difficult to fold when forming the storage box.

本実施形態の収納箱１０の内面に塗布するコート剤、インクなどの塗料、などの塗材は、アクリル系またはスチレン系である。収納箱１０の内面にコート剤を塗布することで、収納箱１０の内面の製造時やユーザによる詰め替え用の積層体２０を収納箱１０に良好に収納することができる。例えば、アクリル系としては、アクリル酸やメタクリル酸樹脂等が挙げられる。なお、本実施形態では、コート剤はアクリル系またはスチレン系を用いているが、これらには限らない。 A coating material such as a coating agent or a coating material such as ink applied to the inner surface of the storage box 10 of the present embodiment is acrylic or styrene. By applying the coating agent to the inner surface of the storage box 10, it is possible to favorably store the stacked body 20 for manufacturing the inner surface of the storage box 10 or for refilling by the user. For example, acrylic acid may be acrylic acid or methacrylic acid resin. In the present embodiment, the coating agent is acrylic or styrene, but is not limited to these.

ここで、本実施形態の収納箱１０の内面の少なくとも一部は、ＪＡＰＡＮ ＴＡＰＰＩ紙パルプ試験方法Ｎｏ．５−１に規定した方法で測定したスムースター平滑度を、３０．０ｋＰａ以下にすることが有用である。スムースター平滑度を３０．０ｋＰａを越えると、収納箱１０の内面の平滑が粗くなる。スムースター平滑度の範囲として、好ましくは、上限が２５．０ｋＰａ以下であり、下限が１．０ｋＰａ以上である。更に好ましくは、下限については、８．０ｋＰａ以上である。 Here, at least a part of the inner surface of the storage box 10 of the present embodiment has a number of Japanese TAPPI paper pulp test method No. It is useful to set the smoother smoothness measured by the method specified in 5-1 to 30.0 kPa or less. When the smoother smoothness exceeds 30.0 kPa, the inner surface of the storage box 10 becomes rough. As the range of smoother smoothness, the upper limit is preferably 25.0 kPa or less and the lower limit is 1.0 kPa or more. More preferably, the lower limit is 8.0 kPa or more.

図４から図７を用いて、収納箱１０に積層体２０を収納することについて説明する。 The storage of the stacked body 20 in the storage box 10 will be described with reference to FIGS. 4 to 7.

先ず、天面１、第１長側面３、第２長側面４、底面２、糊しろ８をそれぞれ折り返し、糊しろ８と第１長側面３を接着剤などで貼り合わせ、四角柱状の筒状にし（図４参照）、ティシュペーパーＰを積層した積層体２０を収納する（図５参照）。そして、図６のように、積層体２０を収納箱１０に収納したら、第２短側面５側の内フラップ６及び７を内側に折り返す。第１短側面５側の内フラップ６および７も折り返し、第１短側面５のタブ１５および第２短側面５のタブ１５をそれぞれ折り返したら、内フラップ６及び７と底面２からなる空間にタブ１５を差し込み、内フラップ６及び７と第１短側面５及び第２短側面５がそれぞれ重なり合うことで閉止され、図１のような収納箱１０に積層体２０が収納される。 First, the top surface 1, the first long side surface 3, the second long side surface 4, the bottom surface 2, and the glue margin 8 are folded back, respectively, and the glue margin 8 and the first long side surface 3 are bonded together with an adhesive or the like to form a rectangular columnar shape. (See FIG. 4), the laminated body 20 in which the tissue paper P is laminated is stored (see FIG. 5). Then, as shown in FIG. 6, when the stacked body 20 is stored in the storage box 10, the inner flaps 6 and 7 on the second short side surface 5 side are folded back inward. The inner flaps 6 and 7 on the side of the first short side 5 are also folded back, and when the tabs 15 of the first short side 5 and the tabs 15 of the second short side 5 are folded back, respectively, a tab is formed in the space formed by the inner flaps 6 and 7 and the bottom surface 2. 15 is inserted, and the inner flaps 6 and 7 and the first short side surface 5 and the second short side surface 5 are overlapped and closed, and the stack 20 is stored in the storage box 10 as shown in FIG.

また、収納箱１０を製造する製造時において、収納箱１０に積層体２０を収納する工程の一例について、図８を用いて、説明する。 In addition, an example of a step of housing the stacked body 20 in the storage box 10 at the time of manufacturing the storage box 10 will be described with reference to FIG. 8.

収納箱１０に積層体２０を収納する工程は、切断された積層体２０を収納箱１０内に収納する工程である。この収納箱１０に積層体２０を収納する工程には、切断された積層体２０を一定間隔で搬送する積層体搬送ラインと、この積層体搬送ラインと同期して空の収納箱１０を一定間隔で搬送する収納箱搬送ラインとが平行に配されている。収納箱搬送ラインには、搬送コンベア２７が備えられており、収納箱搬送ラインに１つずつ送り込まれる収納箱１０は、あらかじめつぶされた折りたたみ状態にある。この状態から、収納箱１０の第１長側面３および第２長側面４を垂直に起立させ、積層体２０が収納される空間Ｒを形成する。この場合、収納箱１０の天面１および底面２と第１長側面３および第２長側面４の短手方向には、収納箱の短側面を封止するための第１短側面５および第２短側面５と内フラップ６、７が開いた状態となっている。積層体２０を収納箱１０の空間Ｒ内に差し入れる場合、収納箱１０の左右何れか一方側に位置する第１短側面５または第２短側面５を開いた状態で挿入する。図４に示す第１短側面５および第２短側面５の開閉状態は、収納箱搬送ラインに沿って配設された短側面開閉手段によって操作される。この短側面開閉手段は、公知の構成を持つものを採用する。積層体２０は、収納箱１０の左右の短側面のうち積層体搬送ラインと対向する側から押し棒３２によって収納箱１０の空間Ｒ内に押し込まれる。 The step of storing the stacked body 20 in the storage box 10 is a step of storing the cut stacked body 20 in the storage box 10.
