Description

本発明はウェットティッシュ等のウェットシートを複数枚積み重ねて収納包装したウェットシート包装体のシート取り出し口に取り付けることで、シート取り出し口の開閉を容易に行うことができるウェットシート包装体の蓋形成ユニット、およびこの蓋形成ユニットを取り付けたウェットシート包装体に関する。 The present invention provides a lid forming unit for a wet sheet packaging body that can be easily opened and closed by attaching to a sheet ejection opening of a wet sheet packaging body in which a plurality of wet sheets such as wet tissues are stacked and stored. And a wet sheet package to which the lid forming unit is attached.

従来よりウェットティッシュやウェットタイプの清掃シート等を収納したウェットシート包装体として、ウェットシートを複数枚積層した積層シートをプラスチックフィルム等により袋状に形成した収納部に収納包装したものが知られている。このようなウェットシート包装体として、シート取り出し口を再密着が可能なフィルム状蓋で密閉し、フィルム状蓋を開封してウェットシートを取り出した後、再びフィルム状蓋でシート取り出し口を密封することでウェットシートの乾燥を防ぐようにしたものが広く用いられていた。 2. Description of the Related Art Conventionally, as a wet sheet package that stores wet tissue, wet type cleaning sheets, and the like, a laminate sheet obtained by laminating a plurality of wet sheets is stored and packaged in a storage portion formed into a bag shape with a plastic film or the like. . As such a wet sheet packaging body, the sheet take-out port is sealed with a re-contactable film-like lid, the film-like lid is opened, the wet sheet is taken out, and then the sheet take-out port is sealed again with the film-like lid. In order to prevent the wet sheet from drying, it has been widely used.

再密着が可能なフィルム状蓋でシート取り出し口を密封しただけのウェットシート包装体は構造が簡単であり安価に提供される反面、フィルム状蓋の開封を両手で行う必要があるため、開封に手間がかかるとともに、フィルム状蓋の開閉を繰り返すと、フィルム状蓋の再接着力が低下するとともに、フィルム状蓋をシワのないように再貼着するのに手間がかかり、シート取り出し口周縁とフィルム状蓋との間に隙間ができ易く、収納されているウェットシートの乾燥防止効果は十分とは言い難かった。 A wet sheet package that simply seals the sheet outlet with a film-like lid that can be re-adhered has a simple structure and is provided at low cost, but it is necessary to open the film-like lid with both hands. Repeatedly opening and closing the film-like lid, it takes time and effort to re-attach the film-like lid without wrinkles, It was easy to form a gap between the film-shaped lid and the wet-drying effect of the wet sheet stored was not sufficient.

一方、フィルム状蓋を囲むように形成された開口部を有する枠体と、当該枠体に開閉自在に設けられ、枠体の表面側から開口部を閉塞する蓋部とを有する蓋体（特許文献１）や、フィルム状蓋を囲むように形成された開口部を有する枠体と、先・後のウェットシートを分離し、かつ後続のウェットシート先端部を保持し得るウェットシート取出口を有し、前記枠体の開口部を開閉できるように構成された中間蓋と、該中間蓋のウェットシート取出口を開閉できる上蓋とを備えた蓋体（特許文献２）を、袋状収納部の上面に取り付けた包装体も知られている。 On the other hand, a lid having a frame having an opening formed so as to surround the film-like lid, and a lid that is provided in the frame so as to be freely opened and closed and closes the opening from the surface side of the frame (patent) Document 1), a frame having an opening formed so as to surround the film-like lid, and a wet sheet outlet that separates the front and rear wet sheets and can hold the leading end of the subsequent wet sheet. And a lid (Patent Document 2) including an intermediate lid configured to open and close the opening of the frame and an upper lid capable of opening and closing a wet sheet outlet of the intermediate lid. A package attached to the top surface is also known.

しかしながら、特許文献１、特許文献２に記載されているような、開閉自在な蓋を有する従来の蓋体は、密閉度を高めるために蓋や枠体の形状、構造は比較的複雑であり、このため嵩張って、運搬時や工場等での保管時に多大なスペースを要したり、複数個を積み重ね保管することが容易ではないといった問題があった。また蓋の形状、構造が複雑になると蓋の重量が重くなり、容易に開蓋させるためにはバネ構造等の複雑な機構を必要とするためコスト高となるという問題があった。 However, the conventional lid body having a lid that can be opened and closed as described in Patent Document 1 and Patent Document 2 has a relatively complicated shape and structure of the lid and the frame body in order to increase the degree of sealing. For this reason, there is a problem that it is bulky and requires a large space during transportation or storage in a factory or the like, and it is not easy to stack and store a plurality. Further, when the shape and structure of the lid become complicated, the weight of the lid becomes heavy, and a complicated mechanism such as a spring structure is required to easily open the lid, resulting in a high cost.

また特許文献２記載の蓋体は、先・後のウェットシートを分離し、かつ後続のウェットシート先端部を保持し得るウェットシート取出口を有する中間蓋を有しているが、このような中間蓋では、先・後のウェットシートを分離する機能は不十分であり、特にウェットシート残量が少なくなった場合には、先・後のウェットシートが分離されずに重なって取り出されてしまうといった問題もあった。 Further, the lid described in Patent Document 2 has an intermediate lid having a wet sheet take-out port that can separate the front and rear wet sheets and can hold the leading end of the subsequent wet sheet. With the lid, the function of separating the front and rear wet sheets is insufficient, especially when the remaining wet sheet is low, the front and rear wet sheets are taken out without being separated. There was also a problem.

本発明は上記の点に鑑みなされたもので、従来の蓋体が有していた問題を解決したウェットシート包装体の蓋形成ユニットおよびウェットシート包装体を提供することを目的とする。 This invention is made | formed in view of said point, and it aims at providing the lid | cover formation unit and wet sheet packaging body of the wet sheet packaging body which solved the problem which the conventional lid body had.

以下、本発明の一態様を図面に基づき説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

図１、図２は本発明のウェットシート包装体の蓋形成ユニット１の一実施形態を示し、該蓋形成ユニット１は、図３に示すようにウェットシートを積み重ねた積層シート２を収納包装した収納部３の外面側に取り付けられるように構成されている。積層シート２は、複数枚のウェットシートを、各ウェットシート間が容易に切り離しできるように折り重ねる等により積層して形成されている。蓋形成ユニット１は、該蓋形成ユニット１を収納部３に取り付けるための取付部４と、該取付部４に連接して設けられた蓋部５を有し、該蓋部５はヒンジ部６を介して開閉自在に構成されている。取付部４には、収納部３のシート取り出し口を囲むように開口部７が設けられている。 1 and 2 show an embodiment of a lid forming unit 1 of a wet sheet packaging body according to the present invention, and the lid forming unit 1 accommodates and wraps a laminated sheet 2 in which wet sheets are stacked as shown in FIG. It is configured to be attached to the outer surface side of the storage unit 3. The laminated sheet 2 is formed by laminating a plurality of wet sheets by, for example, folding them so that the wet sheets can be easily separated. The lid forming unit 1 includes an attaching portion 4 for attaching the lid forming unit 1 to the storage portion 3 and a lid portion 5 provided so as to be connected to the attaching portion 4. The lid portion 5 is a hinge portion 6. It is configured to be openable and closable via. The attachment portion 4 is provided with an opening 7 so as to surround the sheet take-out port of the storage portion 3.

蓋形成ユニット１は、合成樹脂の熱プレス成形、インジェクション成形等により成形することができる。蓋部５と取付部４とは一体に成形したものでも、別体に成形したものでも良い。合成樹脂としては、ポリ塩化ビニル（ＰＶＣ）、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）、ポリスチレン（ＰＳ）、ＡＢＳ樹脂、アクリロニトリル／スチレン共重合体（ＡＳ）、アクリル樹脂、ＰＥＴ、ポリカーボネート（ＰＣ）等が挙げられるが、ポリエチレン、ポリプロピレンが好ましい。 The lid forming unit 1 can be molded by synthetic resin hot press molding, injection molding, or the like. The lid portion 5 and the attachment portion 4 may be integrally molded or may be molded separately. Synthetic resins include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin, acrylonitrile / styrene copolymer (AS), acrylic resin, PET, polycarbonate (PC), etc. However, polyethylene and polypropylene are preferable.

蓋部５は閉蓋時に取付部４に保持され得るように構成され、図１に示す例では、蓋部５に設けられた係合手段８ａと、閉蓋時に蓋部５の係合手段８ａと対応する箇所に設けられた係合手段８ｂとの係合、および蓋部５の周縁内側部に設けられた凸条（または凹条）９ａと、取付部４の周縁内側部に設けられた凹条（または凸条）９ｂとの嵌合とにより、閉蓋時に蓋部５が取付部４に保持されて閉蓋されるように構成されている。蓋部５を取付部４に保持する手段としては、上記した係合手段８ａ、８ｂの係合、凸条と凹条９ａ、９ｂとによる嵌合のいずれか一方でもよいが、両方を設けることで蓋部５の取付部４への保持性が高まるとともに、閉蓋時の密閉性も向上する。特に、蓋部５の周縁部に設けた凸条（または凹条）９ａと、取付部４の周縁部に設けた凹条（または凸条）９ｂとを嵌合させて保持させるようにすると、閉蓋時の密閉性も向上する。凸条（または凹条）９ａと、凹条（または凸条）９ｂとは、図示したように蓋部５、取付部４の周縁部に連続的に設ける場合に限らず、非連続的に設けても良いが、連続的に設けることにより蓋部５の保持性、閉蓋時の密閉性がより向上する。また、ヒンジ部６に近い位置では、ヒンジ部６から離れた位置に比べ、嵌合深さが深くなるよう凸条（または凹条）９ａと、凹条（または凸条）９ｂを構成すると、閉蓋時のヒンジ部付近における密閉性を高めることができる。また、凸条と凹条とは、非直線状部分が多くなるように形成すると、蓋部５の保持性、閉蓋時の密着性を更に高めることができる。凸条（または凹条）と凹条（または凸条）は、一つのみならず複数設けてもよい。また蓋部５や取付部４の周縁に、ホットメルト接着剤を連続的または間欠的に塗布したり、凹条の表面開口部に伸縮性を有するフィルムを展張し、フィルムを伸張させながら凸条が凹条に嵌合するようにする等により、蓋部５の密着性を高めることもできる。蓋部５を閉蓋した時の密着性を高めるための手段は、２つ以上の手段を併用することができる。凹凸条の嵌合や、ホットメルト接着剤により蓋部の密着性を高めると、ウェットシートの乾燥をより効果的に防止できる。 The lid 5 is configured to be held by the mounting portion 4 when the lid is closed. In the example shown in FIG. 1, the engaging means 8a provided on the lid 5 and the engaging means 8a of the lid 5 when the lid is closed. And the engagement means 8b provided at the corresponding location, and the projection (or recess) 9a provided on the inner periphery of the lid 5 and the inner periphery of the mounting portion 4. By fitting with the concave strip (or convex strip) 9b, the lid portion 5 is configured to be held and closed by the attachment portion 4 when the lid is closed. As means for holding the lid portion 5 on the attachment portion 4, either one of the engagement of the engagement means 8a and 8b and the fitting by the ridges and the recesses 9a and 9b may be used, but both are provided. As a result, the retention of the lid 5 on the mounting portion 4 is enhanced, and the airtightness when the lid is closed is improved. In particular, when the convex strip (or concave strip) 9a provided on the peripheral portion of the lid 5 and the concave strip (or convex strip) 9b provided on the peripheral portion of the mounting portion 4 are fitted and held, The airtightness when closing the lid is also improved. The ridges (or ridges) 9a and the ridges (or ridges) 9b are not limited to being provided continuously on the peripheral edge of the lid 5 and the mounting part 4 as shown in the figure, but are provided discontinuously. However, by providing continuously, the holding | maintenance property of the cover part 5 and the airtightness at the time of a lid closing improve more. Further, when the ridge (or ridge) 9a and the ridge (or ridge) 9b are configured so that the fitting depth is deeper at a position close to the hinge section 6 than at a position away from the hinge section 6, The sealing performance in the vicinity of the hinge portion when the lid is closed can be improved. Further, if the ridges and the ridges are formed so as to have more non-linear portions, the retention of the lid 5 and the adhesion at the time of closing can be further enhanced. The number of the ridges (or ridges) and the ridges (or ridges) may be one or more. Further, a hot melt adhesive is applied continuously or intermittently to the periphery of the lid 5 or the mounting portion 4, or a stretchable film is stretched on the surface opening of the concave stripe, and the convex stripe while stretching the film. It is also possible to improve the adhesion of the lid 5 by fitting it into the recess. Two or more means can be used in combination as means for improving the adhesion when the lid 5 is closed. If the adhesiveness of the lid is enhanced by the fitting of the ridges and the hot melt adhesive, the wet sheet can be more effectively prevented from drying.

閉蓋時に蓋部５を取付部４に保持させるための手段としては、上記した方法に限らず、特に図示しないが蓋部５（または取付部４）の周縁に取付部４方向（または蓋部５方向）に突出した、連続または非連続の突出縁を設け、該突出縁を取付部４（または蓋部５）の周縁に外嵌させることにより実現することもできる。 The means for holding the lid portion 5 on the attachment portion 4 when the lid is closed is not limited to the above-described method, and although not particularly shown, the attachment portion 4 direction (or the lid portion) is arranged on the periphery of the lid portion 5 (or attachment portion 4). It can also be realized by providing a continuous or non-continuous protruding edge protruding in five directions and fitting the protruding edge to the periphery of the mounting portion 4 (or the lid portion 5).

本実施形態の蓋形成ユニット１は、取付部４、蓋部５が平板状に形成され、閉蓋時に蓋部５の平面部分と、取付部４の平面部分とが面接触するように構成されている。閉蓋時に蓋部５と取付部４との間に、このような面接触部が形成されるように構成することで、閉蓋時の密閉性がより向上する。また蓋部を平板状とした蓋形成ユニットを取り付けたウェットシート包装体は、積み重ねた時に、積み重ねられた包装体に蓋部跡が形成されて外観低下をきたす虞が少ない。取付部４と蓋部５との面接触部分は、少なくとも一部が接触していればよいが、取付部４の外周面と蓋部５の外周面とが接触するか、取付部４の開口部７の周面が蓋部５と面接触するように形成することが好ましい。蓋部５と取付部４とは、取付部４の平面部面積の３０〜９０％が面接触することが好ましく、４０〜８０％が面接触するように構成することがより好ましい。なお、取付部４、蓋部５が平板状であるとは、ほぼ全体が平板状に形成されていればよく、係合手段や凹凸条等の多少の凹凸や、多少の湾曲があるものでも良い。 The lid forming unit 1 of the present embodiment is configured such that the mounting portion 4 and the lid portion 5 are formed in a flat plate shape, and the flat surface portion of the lid portion 5 and the flat surface portion of the mounting portion 4 are in surface contact when the lid is closed. ing. By configuring so that such a surface contact portion is formed between the lid portion 5 and the attachment portion 4 when the lid is closed, the airtightness when the lid is closed is further improved. In addition, when the wet sheet packaging body to which the lid forming unit having a flat lid portion is attached is stacked, the trace of the lid portion is formed on the stacked packaging body, and there is little possibility that the appearance deteriorates. The surface contact portion between the attachment portion 4 and the lid portion 5 may be at least partially in contact, but the outer peripheral surface of the attachment portion 4 and the outer peripheral surface of the lid portion 5 are in contact with each other or the opening of the attachment portion 4 is opened. It is preferable that the peripheral surface of the portion 7 is formed so as to be in surface contact with the lid portion 5. The lid portion 5 and the attachment portion 4 are preferably configured such that 30 to 90% of the plane area of the attachment portion 4 is in surface contact, and 40 to 80% is in surface contact. In addition, the attachment part 4 and the cover part 5 have a flat plate shape as long as the whole is formed in a flat plate shape, even if there are some unevenness such as engagement means and uneven stripes, and some curvature. good.

蓋形成ユニット１は、蓋部５を取付部４に保持させた状態で可撓性を有するが、蓋形成ユニット１の可撓性は、蓋形成ユニット１を合成樹脂で構成し、蓋部５や取付部４を平板状に形成する等、閉蓋時の嵩高さを小さくする、すなわち厚みを薄くすることにより実現でき、このように構成すると閉蓋時の積み重ね性も向上するため、複数個を積み重ねて運搬、保管することが容易となるとともに、運搬、保管スペースを小さくできる。このため蓋形成ユニット１をウェットシート包装体の製造工場で製造する際の作業性が向上するとともに、運搬、保管コストの低減化を図ることができる。また樹脂材料使用量を少なくすることが可能であり、環境への負荷を少なくすることができる。蓋部５を取付部４に保持させた状態での蓋形成ユニット１の嵩高さは、２〜６ｍｍが好ましいが、３〜６ｍｍがより好ましい。 The lid forming unit 1 has flexibility in a state where the lid portion 5 is held by the attachment portion 4. However, the flexibility of the lid forming unit 1 is that the lid forming unit 1 is made of synthetic resin, and the lid portion 5 The mounting portion 4 can be realized by reducing the bulkiness at the time of closing the lid, that is, by reducing the thickness, such as by forming a flat plate shape. It is easy to stack and transport and store and to reduce the transport and storage space. For this reason, while improving the workability | operativity at the time of manufacturing the lid | cover formation unit 1 in the manufacturing plant of a wet sheet packaging body, transportation and storage cost can be reduced. In addition, the amount of resin material used can be reduced, and the burden on the environment can be reduced. The bulkiness of the lid forming unit 1 in a state where the lid portion 5 is held by the attachment portion 4 is preferably 2 to 6 mm, and more preferably 3 to 6 mm.

蓋部５は、取付部４への保持が解除された際に、図２に示すように容易に開蓋する易開蓋性を有している。蓋部５の易開蓋性は、蓋部５を形成する樹脂の弾性や、ヒンジ部６にバネを取り付ける等により実現できるが、特にヒンジ部６の樹脂弾性により易開蓋性が付与されていることが好ましい。また蓋部５が取付部４側に向かって凸状に湾曲するように形成することによっても、蓋部５に易開蓋性を付与することができる。蓋部５が易開蓋性を有することにより、蓋部５の取付部４への保持を解除するだけで容易に開蓋が可能であり、片手で蓋を開蓋することも可能となる。 The lid portion 5 has an easy-opening property that easily opens as shown in FIG. 2 when the holding to the attachment portion 4 is released. The easy opening of the lid part 5 can be realized by the elasticity of the resin forming the lid part 5 or by attaching a spring to the hinge part 6. In particular, the easy opening ability is given by the resin elasticity of the hinge part 6. Preferably it is. Moreover, easy-opening property can be provided to the cover part 5 also by forming so that the cover part 5 may curve in the convex shape toward the attachment part 4 side. Since the lid portion 5 has an easy-opening property, the lid portion 5 can be easily opened simply by releasing the holding of the lid portion 5 to the attachment portion 4, and the lid can be opened with one hand.

ヒンジ部６は、蓋部５を取付部４との境界部で折り曲げて形成したり、Ｖ字状等の切れ込みを入れる等の方法で形成することができる。 The hinge portion 6 can be formed by bending the lid portion 5 at the boundary with the attachment portion 4 or by forming a V-shaped cut or the like.

蓋形成ユニット１は、ホットメルト等の接着剤による接着、超音波接着、熱接着等の方法で収納部３表面に取り付けることができる。 The lid forming unit 1 can be attached to the surface of the storage unit 3 by a method such as bonding with an adhesive such as hot melt, ultrasonic bonding, or thermal bonding.

図４、図５は蓋形成ユニット１の異なる実施形態を示している。この蓋形成ユニット１は、シート取り出し穴１０を有する抵抗付与部材１１が、取付部４から取付部４の開口部７に向かって突出形成されている。抵抗付与部材１１は、一端側を固定端１１ａとし、他端側を自由端１１ｂとして形成されている。抵抗付与部材１１は、自由端１１ｂ側が、図６に示すように、積層シート２を収納した収納部３のシート取り出し口１２から収納部３内に侵入してウェットシートに抵抗を付与するように付勢されている。抵抗付与部材１１は、蓋部５、取付部４と一体または別体に成形して設けることができる。抵抗付与部材１１は、該抵抗付与部材１１を構成する樹脂の弾性力や、抵抗付与部材１１を湾屈曲させることによりウェットシートに抵抗を付与する付勢力が備えられる。抵抗付与部材１１を別体に構成した場合には、蓋部５や取付部４と異なる材質で形成が容易となり、形状、構造の自由度も向上する。例えば抵抗付与部材１１の固定端１１ａ付近を、自由端がウェットシート方向に向くように屈曲させたり、凹湾曲させる等により湾屈曲させる。また、抵抗付与部材１１は、固定端１１ａ側を自由端１１ｂ側より肉厚に形成したり、固定端１１ａ側の周縁にリブや折り曲げ部を形成することで、固定端１１ａ側を自由端１１ｂ側より高強度に形成することができ、ウェットシートに抵抗を与える付勢力を高めることができる。さらに抵抗付与部材１１の固定端１１ａ付近から自由端側をウェットシート方向に屈曲させるか、屈曲可能に構成し、使用時に屈曲させた自由端側と固定端側とが一定角度で保持されるように係止手段等によって、抵抗付与部材１１の自由端側とを固定端側とを固定保持するようしてもよい。抵抗付与部材１１の自由端側と固定端側とが一定角度に保持されるように自由端側と固定端側を係止保持すると、抵抗付与部材１１からウェットシートへ与えられる抵抗力が使用中に低下するのを防止できる。なお、抵抗付与部材１１は、蓋部５よりも厚く構成することが好ましい。また、開口部７は、取付部４に囲まれた開口として形成されている場合に限らず、取付部４の外側と連通していても良い。 4 and 5 show different embodiments of the lid forming unit 1. In the lid forming unit 1, a resistance applying member 11 having a sheet take-out hole 10 is formed so as to protrude from the attachment portion 4 toward the opening portion 7 of the attachment portion 4. The resistance applying member 11 is formed such that one end side is a fixed end 11a and the other end side is a free end 11b. As shown in FIG. 6, the resistance applying member 11 enters the storage unit 3 from the sheet take-out port 12 of the storage unit 3 that stores the laminated sheet 2 and applies resistance to the wet sheet, as shown in FIG. 6. It is energized. The resistance imparting member 11 can be provided integrally or separately with the lid portion 5 and the attachment portion 4. The resistance imparting member 11 is provided with an elastic force of a resin constituting the resistance imparting member 11 and an urging force that imparts resistance to the wet sheet by bending the resistance imparting member 11. When the resistance applying member 11 is configured as a separate body, it can be easily formed of a material different from that of the lid portion 5 and the attachment portion 4, and the degree of freedom in shape and structure is improved. For example, the vicinity of the fixed end 11a of the resistance applying member 11 is bent so that the free end is directed toward the wet sheet, or is bent concavely. Further, the resistance applying member 11 is formed such that the fixed end 11a side is thicker than the free end 11b side, or a rib or a bent portion is formed on the periphery of the fixed end 11a side so that the fixed end 11a side is the free end 11b. It can be formed with higher strength than the side, and the urging force that gives resistance to the wet sheet can be increased. Further, the free end side of the resistance applying member 11 is bent in the wet sheet direction from the vicinity of the fixed end 11a or bendable so that the free end side and the fixed end side bent during use are held at a constant angle. Further, the free end side of the resistance applying member 11 and the fixed end side may be fixedly held by a locking means or the like. When the free end side and the fixed end side are locked and held so that the free end side and the fixed end side of the resistance applying member 11 are held at a fixed angle, the resistance force applied from the resistance applying member 11 to the wet sheet is in use. Can be prevented. The resistance applying member 11 is preferably configured to be thicker than the lid 5. Further, the opening 7 is not limited to being formed as an opening surrounded by the attachment portion 4, and may be communicated with the outside of the attachment portion 4.

ウェットシート包装体を初めて開封する際には、蓋部５を開蓋し、収納部３のシート取り出し口１２を開封すると、図６に示すようにシート取り出し口１２方向に付勢されている抵抗付与部材１１の自由端１１ｂ側がシート取り出し口１２から収納部３内に侵入し、収納部３内のウェットシートに抵抗が付与される。シート取り出し口１２は、一般にフィルム状蓋により封止されているか、シート取り出し口１２が容易に開口形成されるように収納部３にハーフカットが施されて易開封性を有するように構成されているため、抵抗付与部材１１の自由端１１ｂ側を持ち上げて、シート取り出し口１２を封止しているフィルム状蓋を剥離したり、ハーフカット部を除去することで、シート取り出し口１２を開口させることができる。 When the wet sheet package is opened for the first time, when the lid 5 is opened and the sheet takeout port 12 of the storage unit 3 is opened, the resistance biased toward the sheet takeout port 12 as shown in FIG. The free end 11 b side of the applying member 11 enters the storage unit 3 from the sheet take-out port 12, and resistance is applied to the wet sheet in the storage unit 3. The sheet take-out port 12 is generally sealed with a film-like lid, or is configured so that the storage unit 3 is half-cut so that the sheet take-out port 12 is easily opened and has an easy-open property. Therefore, the sheet take-out port 12 is opened by lifting the free end 11b side of the resistance applying member 11 and peeling off the film-like lid that seals the sheet take-out port 12 or by removing the half-cut portion. be able to.

ウェットシートを取り出す際に、最上部のウェットシート２ａの先端部を、抵抗付与部材１１のシート取り出し穴１０から引き出すと、抵抗付与部材１１によるウェットシートへの押圧力と、シート取り出し穴１０とウェットシートとの間の摩擦力とにより、ウェットシートに抵抗が与えられて、先のウェットシートが後続のウェットシートから切り離され、ウェットシートを一枚ずつ分離して取り出すことができる。抵抗付与部材１１のシート取り出し穴１０には、後続のウェットシートが保持されるため、再度ウェットシートを取り出すための作業が容易であるとともに、抵抗付与部材１１が弾性力を有すると、閉蓋した際に、シート取り出し穴１０に保持された後続のウェットシートを抵抗付与部材１１の弾性力により、収納部内に容易に収納して閉蓋することができる。 When the top end of the wet sheet 2a is pulled out from the sheet take-out hole 10 of the resistance imparting member 11 when the wet sheet is taken out, the pressing force to the wet sheet by the resistance imparting member 11, the sheet take-out hole 10 and the wet The frictional force between the sheets gives resistance to the wet sheet, the previous wet sheet is cut off from the subsequent wet sheet, and the wet sheets can be separated and taken out one by one. Since the subsequent wet sheet is held in the sheet take-out hole 10 of the resistance applying member 11, the operation for taking out the wet sheet again is easy, and the resistance applying member 11 is closed when the resistance applying member 11 has an elastic force. At this time, the subsequent wet sheet held in the sheet take-out hole 10 can be easily stored in the storage unit and closed by the elastic force of the resistance applying member 11.

収納部３のシート取り出し口１２を開口させるためのハーフカットが施されている場合等、使用前に抵抗付与部材１１の押圧力によりハーフカット部が開封されてしまわないように、抵抗付与部材１１は、蓋部５に脱離可能に保持されるように構成することが好ましい。例えば図４に示すように、抵抗付与部材１１と、蓋部５とに設けた係合手段８ａ，８ｂによる係止により、抵抗付与部材１１を脱離可能に蓋部５に保持し、開蓋により蓋部５による保持が解除されることで、抵抗付与部材１１の付勢力が発揮されるようにしても良い。また、抵抗付与部材１１と蓋部５とを、部分的にホットメルト接着剤等により剥離可能に接着することにより、抵抗付与部材１１を脱離可能に蓋部５に保持させるようにしても良い。また図示しないが、抵抗付与部材１１と取付部４との間を、容易に切除可能な支持部材で接合しておき、使用時に当該支持部材を切除することで、抵抗付与部材１１の付勢力が発揮されるようにしても良い。 When the half cut for opening the sheet take-out port 12 of the storage unit 3 is performed, the resistance applying member 11 is prevented from being opened by the pressing force of the resistance applying member 11 before use. Is preferably configured to be detachably held by the lid 5. For example, as shown in FIG. 4, the resistance applying member 11 is detachably held on the lid 5 by the engagement by the engagement means 8 a and 8 b provided on the resistance applying member 11 and the lid 5, and the lid is opened. Thus, the urging force of the resistance applying member 11 may be exhibited by releasing the holding by the lid 5. Alternatively, the resistance applying member 11 and the lid 5 may be partially detachably bonded with a hot melt adhesive or the like so that the resistance applying member 11 is detachably held on the lid 5. . Moreover, although not shown in figure, the urging | biasing force of the resistance provision member 11 is joined between the resistance provision member 11 and the attaching part 4 with the support member which can be easily excised, and the support member is excised at the time of use. You may make it show.

抵抗付与部材１１を蓋部５に脱離可能に保持させたり、支持部材等により取付部４に脱離可能に保持させる場合、使用前に抵抗付与部材１１がハーフカット部に接触してハーフカット部を破損することがないように、抵抗付与部材１１の下面が、取付部４の下面位置より上方に位置するように、抵抗付与部材１１を保持させることが好ましい。また抵抗付与部材１１を、蓋部５あるいは取付部４に脱離可能に保持させることにより、積み重ね性、低嵩高性が良好となり、運搬、保管時のスペースを小さくでき、運搬、保管コストの低減ができる。 When the resistance applying member 11 is detachably held on the lid 5 or is detachably held on the mounting portion 4 by a support member or the like, the resistance applying member 11 comes into contact with the half cut portion before use and is half cut. It is preferable to hold the resistance applying member 11 so that the lower surface of the resistance applying member 11 is located above the lower surface position of the mounting portion 4 so that the portion is not damaged. In addition, the resistance imparting member 11 is detachably held on the lid 5 or the attachment portion 4 so that stackability and low bulkiness are improved, space for transportation and storage can be reduced, and transportation and storage costs are reduced. Can do.

抵抗付与部材１１は、図７に示すようにウェットシートを引き出す際に、シートの引き出しに伴って上方に引き上げられ、復元力によりシートに抵抗を付与する可撓弾性を有していると、ウェットシートに対してより確実に抵抗を与えることができ、前後のウェットシートの分離性が向上する。抵抗付与部材１１は、積層シート２を収納した収納部３のシート取り出し口１２から収納部３内に侵入してウェットシートに抵抗を付与するように付勢されていると、ウェットシートに与える負荷を大きくできるが、必ずしもシート取り出し口１２方向への押圧力を有するように付勢されていなくても良い。抵抗付与部材１１が、シートの引き出しに伴って上方に引き上げられ、復元力によりシートに抵抗を付与する可撓弾性を有している場合、抵抗付与部材がシート取り出し口１２方向への押圧力を有するように付勢されていない場合でも、ウェットシートを引き出す際にウェットシートに強い抵抗力を付与できる。
なお、抵抗付与部材１１の「可撓弾性」とは、ウェットシートを引き出す際にウェットシートの引き出しに伴って撓んで引き上げられる可撓性と、引き上げられた抵抗付与部材が元の状態に復元しようとする弾性力とを併せ持つことを意味する。 When the resistance imparting member 11 has a flexible elasticity that pulls upward when the wet sheet is pulled out as illustrated in FIG. 7 and imparts resistance to the sheet by a restoring force. Resistance can be more reliably applied to the sheet, and the separation of the front and rear wet sheets is improved. When the resistance applying member 11 is energized so as to enter the storage unit 3 from the sheet take-out port 12 of the storage unit 3 storing the laminated sheet 2 and apply resistance to the wet sheet, a load applied to the wet sheet However, it is not always necessary to be biased so as to have a pressing force in the direction of the sheet take-out port 12. When the resistance applying member 11 is pulled up upward as the sheet is pulled out and has a flexible elasticity that applies resistance to the sheet by a restoring force, the resistance applying member exerts a pressing force in the direction of the sheet take-out port 12. Even when the wet sheet is not biased, a strong resistance can be applied to the wet sheet when the wet sheet is pulled out.
The “flexible elasticity” of the resistance applying member 11 means the flexibility to bend and lift when the wet sheet is pulled out, and the restored resistance applying member to be restored to the original state. It means having both the elastic force.

抵抗付与部材１１のシート取り出し穴１０は、図８、図９に示すように主穴１０ａと、該主穴１０ａと連通した複数の補助穴１０ｂとで構成しても良い。この形態のシート取り出し穴１０では、図１０に示すように、主穴１０ａと、補助穴１０ｂの両方からウェットシートに抵抗を付与でき、主穴１０ａと補助穴１０ｂとから、異なる強さの抵抗を付与することができる。シート取り出し穴１０は、図４、図８等に図示した形状に限らず、図１１に示すような各種の形状とすることができる。またシート取り出し穴１０は、抵抗付与部材１１内に収まるように形成されている場合に限らず、抵抗付与部材１１から開口部７側に連通する形状に形成することもできる。
上記例では、ウェットシートを抵抗付与部材１１のシート取り出し穴１０を経て取り出す場合を示したが、図１５に示すように開口部７周縁と、抵抗付与部材１１の周縁との間に、ウェットシート取り出し用の空隙を設け、該空隙からウェットシート２ａを引き出すこともできる。図１５に示す形態では、ウェットシートを開口部７周縁と、抵抗付与部材１１の周縁との間のウェットシート取り出し用の空隙から引き出すことも、シート取り出し穴１０から取り出すこともでき、引き出すウェットシートに異なる抵抗力を付与することもできる。
図１６は抵抗付与部材１１の異なる形態を示し、開口部７周縁と、抵抗付与部材１１の周縁との間の空隙からウェットシートを引き出す場合、図１６（ｃ）に示すよう抵抗付与部材１１は、シート取り出し穴を有していなくても良い。また図１６（ａ）に示すように、抵抗付与部材１１のシート取り出し穴１０と、開口部７との間に切り込み１５等の連通部を設けると、ウェットシートはシート取り出し穴１０、抵抗付与部材１１の周縁と開口部７の周縁との間の空隙の一方から任意に引き出すこともでき、また切り込み１５等の連通部を介してシート取り出し穴１０と、抵抗付与部材１１の周縁と開口部７の周縁との間の空隙とを利用して引き出すこともできる。図１６（ｂ）は抵抗付与部材１１の周縁に凹凸１６を形成した例を示す。この場合、抵抗付与部材１１周縁の凹凸１６と、開口部７周縁との間の空隙からウェットシートを引き出す場合と、シート取り出し穴１０からウェットシートを取り出す場合とで、大きさのより異なる負荷をウェットシートに与えることが可能となる。 The sheet take-out hole 10 of the resistance applying member 11 may be constituted by a main hole 10a and a plurality of auxiliary holes 10b communicating with the main hole 10a as shown in FIGS. In the sheet take-out hole 10 of this form, as shown in FIG. 10, resistance can be given to the wet sheet from both the main hole 10a and the auxiliary hole 10b, and resistances of different strengths can be obtained from the main hole 10a and the auxiliary hole 10b. Can be granted. The sheet take-out hole 10 is not limited to the shape illustrated in FIGS. 4 and 8 and may have various shapes as illustrated in FIG. Further, the sheet take-out hole 10 is not limited to be formed so as to be accommodated in the resistance applying member 11, but may be formed in a shape communicating from the resistance applying member 11 to the opening 7 side.
In the above example, the wet sheet is taken out through the sheet take-out hole 10 of the resistance applying member 11. However, as shown in FIG. 15, the wet sheet is provided between the periphery of the opening 7 and the peripheral edge of the resistance applying member 11. It is also possible to provide a take-out gap and draw out the wet sheet 2a from the gap. In the form shown in FIG. 15, the wet sheet can be drawn out from the gap for taking out the wet sheet between the periphery of the opening 7 and the periphery of the resistance imparting member 11 or can be taken out from the sheet take-out hole 10. It is also possible to give different resistances to.
FIG. 16 shows a different form of the resistance applying member 11, and when the wet sheet is pulled out from the gap between the periphery of the opening 7 and the periphery of the resistance applying member 11, the resistance applying member 11 is as shown in FIG. The sheet take-out hole may not be provided. Further, as shown in FIG. 16A, when a communicating portion such as a notch 15 is provided between the sheet take-out hole 10 of the resistance applying member 11 and the opening 7, the wet sheet becomes the sheet take-out hole 10 and the resistance applying member. 11 can be arbitrarily pulled out from one of the gaps between the peripheral edge of the opening 11 and the peripheral edge of the opening 7, and the sheet take-out hole 10, the peripheral edge of the resistance applying member 11, and the opening 7 through the communication portion such as the notch 15. It is also possible to pull out by utilizing the gap between the peripheral edges of the two. FIG. 16B shows an example in which the unevenness 16 is formed on the periphery of the resistance applying member 11. In this case, when the wet sheet is pulled out from the gap between the unevenness 16 on the periphery of the resistance applying member 11 and the periphery of the opening 7 and when the wet sheet is pulled out from the sheet take-out hole 10, different loads of different sizes are applied. It becomes possible to give to a wet sheet.

抵抗付与部材１１は、１つだけ設ける場合に限らず、複数設けることができる。図１２に示す態様では、２つの抵抗付与部材１３ａ、１３ｂを、取付部４の開口部７の相対向するそれぞれの短辺側に設けた場合を示している。抵抗付与部材１３ａ、１３ｂのそれぞれの自由端側には、自由端から開口部７に連通する形状のシート取り出し穴１０、１０が設けられている。この態様の抵抗付与部材１１は、最初のウェットシートを取り出す際に、抵抗付与部材１３ａ、１３ｂの自由端を押し下げたときに、抵抗付与部材が１つの場合よりも、抵抗付与部材１３ａ、１３ｂの自由端間に形成される、ウェットシートを取り出すための空間大きさが大きくなり、シートを指でつまんで容易に取り出すことができる。またシート取り出し穴１０に保持される後続のウェットシート先端部を収納するための空間が広くなるため、容易に後続のウェットシート先端部を収納することができ、ウェットシートの先端部を指で収納部内に押し込んで収納する場合のように、細菌によるウェットティッシュの汚染、カビの発生を防止できる。特にベビー用ウェットシートの場合に好ましい。複数の抵抗付与部材を設ける場合、各抵抗付与部材は、長さ、形状、厚み、材質、強度（弾性、硬度等）、動き方やシートへの抵抗付与性等が同一であっても、異なっていても良い。また各抵抗付与部材は、いずれかの抵抗付与部材の自由端が上下に動くことができるように構成されていればよく、複数設けられた抵抗付与部材の一部は、自由端の可動範囲が異なっていてもよいし、上下動できないように構成されていても良い。複数の抵抗付与部材は、上下、左右にずれた位置に設けられても良く、抵抗付与部材１３ａ、１３ｂの自由端が、抵抗付与部材の厚さ方向において接触して重なったり、離間して重なるような位置に設けられていても良い。２以上の抵抗付与部材を設けると、各抵抗付与部材からシートに与える抵抗を容易に高めることができる。複数の抵抗付与部材を設ける場合、図１２に示したように相対向する短辺側に設ける場合に限らず、相対向する長辺に設けたり、短辺と長辺に設けたり、相対向長辺と、相対向する短辺とにそれぞれ設けることもできる。また同一の辺に２以上の抵抗付与部材を設けることもできる。 The resistance applying member 11 is not limited to being provided alone, and a plurality of resistance applying members 11 may be provided. In the aspect shown in FIG. 12, a case is shown in which two resistance applying members 13 a and 13 b are provided on the opposite short sides of the opening 7 of the attachment portion 4. On the free end side of each of the resistance applying members 13a and 13b, sheet take-out holes 10 and 10 having a shape communicating from the free end to the opening 7 are provided. When the resistance applying member 11 of this aspect takes down the free end of the resistance applying members 13a and 13b when the first wet sheet is taken out, the resistance applying members 13a and 13b have a higher resistance than the case of one resistance applying member. The space size for taking out the wet sheet formed between the free ends is increased, and the sheet can be easily taken out by pinching with a finger. Further, since the space for storing the leading end of the subsequent wet sheet held in the sheet take-out hole 10 is widened, the leading end of the succeeding wet sheet can be easily stored, and the leading end of the wet sheet is stored with a finger. As in the case of being pushed in and housed, the wet tissue can be prevented from being contaminated by bacteria and the generation of mold. It is particularly preferable for baby wet sheets. When providing a plurality of resistance imparting members, each resistance imparting member is different even if the length, shape, thickness, material, strength (elasticity, hardness, etc.), movement method, and resistance imparting property to the sheet are the same. May be. Each resistance applying member only needs to be configured so that the free end of one of the resistance applying members can move up and down, and some of the plurality of resistance applying members have a movable range of the free end. They may be different or may be configured not to move up and down. The plurality of resistance imparting members may be provided at positions shifted vertically and horizontally, and the free ends of the resistance imparting members 13a and 13b are in contact with each other in the thickness direction of the resistance imparting member and overlap each other. It may be provided in such a position. When two or more resistance imparting members are provided, the resistance imparted to the sheet from each resistance imparting member can be easily increased. When providing a plurality of resistance-applying members, it is not limited to the case where they are provided on the opposite short sides as shown in FIG. 12, but is provided on the opposite long sides, the short sides and the long sides, or the opposite lengths. It can also be provided on each of the sides and the opposing short sides. Two or more resistance applying members can be provided on the same side.

複数の抵抗付与部材を設ける場合、それぞれの抵抗付与部材に設けられるシート取り出し穴は、同一形状であっても異なる形状であっても良い。また一方の抵抗付与部材には開口部７に連通する取り出し穴を設け、他の抵抗付与部材には開口部に連通していない取り出し穴を設けるように構成することもできる。図１３は、２つの抵抗付与部材を相対向して設けた態様における、シート取り出し穴１０の異なる形態を示し、図１３（ａ）から図１３（ｃ）は、各抵抗付与部材１３ａ、１３ｂに、同一形状のシート取り出し穴１０を設けた例を示し、図１３（ｄ）、図１３（ｅ）は、各抵抗付与部材１３ａ、１３ｂに、異なる形状のシート取り出し穴１０を設けた例を示す。抵抗付与部材１３ａ、１３ｂに設けられるシート取り出し穴は、取り出すウェットシートに抵抗を与えることができればよいが、図１３（ｃ）に示すように各抵抗付与部材１３ａ，１３ｂの自由端に幅狭の延設部１４ａ、１４ｂを設け、一方の延設部１４ａと、他方の延設部１４ｂとを交叉させてシート取り出し穴１０を形成するように構成すると、ウェットシートの引き出しに伴って、シート取り出し穴１０の開口面積が減少し、開口面積の減少につれて、取り出されるウェットシートに加えられる抵抗力も高くなるため、取り出そうとするウェットシートの切り離しがより確実に行える。また図１３（ａ）のように、シート取り出し穴１０を、開口の大きな穴と小さな穴とで構成すると、小さな穴によるシートの保持性が高まる。 When a plurality of resistance applying members are provided, the sheet take-out holes provided in each of the resistance applying members may have the same shape or different shapes. Further, one resistance applying member may be provided with an extraction hole communicating with the opening 7, and the other resistance applying member may be provided with an extraction hole not communicating with the opening. FIG. 13 shows different forms of the sheet take-out hole 10 in an embodiment in which two resistance applying members are provided facing each other, and FIGS. 13 (a) to 13 (c) show the resistance applying members 13a and 13b. FIG. 13 (d) and FIG. 13 (e) show examples in which differently shaped sheet take-out holes 10 are provided in the resistance applying members 13a and 13b, respectively. . The sheet take-out holes provided in the resistance applying members 13a and 13b only need to be able to give resistance to the wet sheet to be taken out. However, as shown in FIG. 13C, a narrow width is provided at the free ends of the respective resistance applying members 13a and 13b. When the extending portions 14a and 14b are provided and the one extending portion 14a and the other extending portion 14b are crossed to form the sheet take-out hole 10, the sheet is taken out as the wet sheet is pulled out. Since the opening area of the hole 10 decreases and the opening area decreases, the resistance applied to the wet sheet to be taken out also increases, so that the wet sheet to be taken out can be more reliably separated. Further, as shown in FIG. 13A, when the sheet take-out hole 10 is constituted by a hole having a large opening and a small hole, the retainability of the sheet by the small hole is enhanced.

抵抗付与部材１１は、積層シート２を収納包装した収納部３に設けられるシート取り出し口１２の大きさと略同じ大きさに形成する場合に限らず、図１４に示すように抵抗付与部材１１の、シート取り出し口１２側に突出する長さを短く構成することができる。収納部３内のウェットシートを取り出す際に、２枚目以降のウェットシートは、その先端部が抵抗付与部材１１に保持されるように構成されているが、図１４に示すように、シート取り出し口１２と、抵抗付与部材１１との間に、十分な面積の開口部分が形成されるように抵抗付与部材１１を構成すると、該開口部分から２枚目以降のウェットシートの先端部を収納部内に容易に収納することができ、ウェットシートの先端部を指で収納部内に押し込んで収納する場合のように、汚染されることがないため残りのウェットシートのカビ発生等を防止できる。 The resistance applying member 11 is not limited to the case where the resistance applying member 11 is formed to have substantially the same size as the size of the sheet take-out port 12 provided in the storage unit 3 in which the laminated sheet 2 is stored and packaged. The length protruding toward the sheet take-out port 12 can be shortened. When the wet sheet in the storage unit 3 is taken out, the second and subsequent wet sheets are configured such that the tip portions thereof are held by the resistance applying member 11, but as shown in FIG. When the resistance imparting member 11 is configured such that an opening portion having a sufficient area is formed between the mouth 12 and the resistance imparting member 11, the leading end portions of the second and subsequent wet sheets from the opening portion are placed in the storage portion. Therefore, unlike the case where the front end portion of the wet sheet is pushed into the storage portion with the finger and stored, it is not contaminated, so that it is possible to prevent the remaining wet sheet from becoming moldy.
