The base-material leading end part is folded toward the fastener material side and covers part of the surface of the fastener material, and also joined to the surface of the fastener material. The fastener material is not fastened to its mating fastener material and is used as a tab used to peel the fastener material.

Description

本発明は、止着テープおよびこの止着テープを備える使い捨ておむつに関する。   The present invention relates to a fastening tape and a disposable diaper provided with the fastening tape.

従来から図7に示すように、平形の使い捨ておむつ51の後身頃51aと前身頃51bとを固定するために用いられる止着テープ61であって、後身頃51aの側辺部に取り付けられるシート状のテープ基材62を有し、このテープ基材62の一面上に面ファスナの一方を構成する止着材63を接合した構造の止着テープ61が知られている(特許文献1参照)。   Conventionally, as shown in FIG. 7, it is a fastening tape 61 used for fixing the back body 51a and the front body 51b of a flat disposable diaper 51, and is a sheet-like attached to the side part of the back body 51a. There is known a fastening tape 61 having a structure in which a fastening material 63 that constitutes one of the surface fasteners is joined to one surface of the tape base material 62 (see Patent Document 1).

上記面ファスナの一方を構成する止着材63は、所定の幅寸法wを有し、その全幅に亙って、前身頃51bの外面に接合された面ファスナの他方を構成する止着材71に対し止着される。 The fastening material 63 constituting one of the surface fasteners has a predetermined width dimension w 0 , and the fastening material constituting the other of the surface fasteners joined to the outer surface of the front body 51b over the entire width. It is fixed to 71.

また、テープ基材62には、止着材63よりもテープ先端側へ突出する基材先端部62aが設けられ、この基材先端部62aが、一対の止着材63,71よりなる面ファスナを剥離する(引き剥がす)ときの摘まみ片64として利用される。   Further, the tape base material 62 is provided with a base material front end portion 62 a that protrudes further toward the tape front end side than the fastening material 63, and this base material front end portion 62 a is a surface fastener made of a pair of fastening materials 63, 71. It is used as a knob 64 when peeling (peeling).

しかしながら、この従来技術においては上記したように、面ファスナを剥離するときに利用される摘まみ片64がテープ基材62の基材先端部62aのみによって構成されているため、以下のような不都合がある。   However, in this prior art, as described above, since the knob 64 used when peeling the hook and loop fastener is constituted only by the base end portion 62a of the tape base 62, the following inconvenience is caused. There is.

すなわち、テープ基材62は一般に不織布などの薄く柔らかい素材シートによって形成されている。したがって摘まみ片64も薄く柔らかいため、摘まみ片64はこれを摘まみにくく引っ張りにくい。   That is, the tape base material 62 is generally formed of a thin and soft material sheet such as a nonwoven fabric. Accordingly, since the knob 64 is thin and soft, the knob 64 is difficult to pick and pull.

また、面ファスナを剥離する際に摘まみ片64を摘まんで引っ張るとき、止着材63は直接摘ままれることがなく引っ張られることがない。したがってテープ基材62と止着材63との接合強度が小さく止着材63,71同士の止着強度が大きい場合、止着材63,71同士は止着したままで、テープ基材62が止着材63から剥がれてしまうことがある。   Further, when the knob 64 is picked and pulled when the surface fastener is peeled off, the fastening member 63 is not directly picked and is not pulled. Therefore, when the bonding strength between the tape base material 62 and the fastening material 63 is small and the fastening strength between the fastening materials 63 and 71 is large, the fastening materials 63 and 71 are still fastened and the tape base material 62 is fixed. It may peel off from the fastening material 63.

In the fastening tape in which the fastening material is bonded onto one surface of the tape base material, the tape base material integrally has a base material tip portion protruding toward the tape tip side from the fastening material, and the base The material front end portion is folded back to the fastening material side to cover a part of the surface of the fastening material and bonded onto the surface of the fastening material, and the fastening material is covered by the base material front end portion. It is characterized in that it is not fastened to the other party's fastening material in the broken area, but is a picking piece when the fastening material is peeled off.

また、本発明の請求項2による止着テープは、上記した請求項1記載の止着テープにおいて、前記基材先端部は、前記止着材の幅寸法の1/2以下の領域にて前記止着材の表面を覆っていることを特徴とする。   Moreover, the fastening tape according to claim 2 of the present invention is the fastening tape according to claim 1, wherein the tip of the base material is in the region of ½ or less of the width dimension of the fastening material. It is characterized by covering the surface of the fastening material.

また、本発明の請求項3による止着テープは、上記した請求項1または2記載の止着テープにおいて、前記基材先端部は、その一面上に設定した止着機能により前記止着材の表面上に接合され、または接着、圧着、融着もしくは溶着による固定手段により前記止着材の表面上に接合されていることを特徴とする。   The fastening tape according to claim 3 of the present invention is the fastening tape according to claim 1 or 2, wherein the tip of the base material is formed of the fastening material by a fastening function set on one surface thereof. It is bonded on the surface, or is bonded on the surface of the fixing material by a fixing means by adhesion, pressure bonding, fusion or welding.

また、本発明の請求項4による止着テープは、上記した請求項1ないし3のいずれか1項に記載の止着テープにおいて、前記摘まみ片は、前記テープ基材、止着材の基材部、止着材の止着片部および基材先端部の積層構造よりなることを特徴とする。   The fastening tape according to claim 4 of the present invention is the fastening tape according to any one of claims 1 to 3, wherein the knob is a base of the tape base material and the fastening material. It consists of the laminated structure of a material part, the fastening piece part of a fastening material, and a base-material tip part.

更にまた、本発明の請求項5による使い捨ておむつは、上記した請求項1ないし4のいずれか1項に記載の止着テープを当該おむつの左右で対称に備えることを特徴とする。   Furthermore, the disposable diaper according to claim 5 of the present invention is characterized in that the fastening tape according to any one of claims 1 to 4 is provided symmetrically on the right and left of the diaper.

上記構成を備える本発明の止着テープにおいては、テープ基材の一面上に止着材が接合されるとともにテープ基材に止着材よりもテープ先端側へ突出する基材先端部が一体に設けられていると云う前提のもとで、テープ基材の基材先端部が止着材側へ折り返されて止着材の表面の一部を覆うとともに止着材の表面上に接合され、止着材が基材先端部によって覆われた領域において止着機能を停止して相手方の止着材に止着されず止着材剥離時の摘まみ片とされているために、テープ基材、止着材および基材先端部が重ねられた積層構造よりなる摘まみ片が形成されている。したがってこの積層構造よりなる摘まみ片は、従来の1層構造よりなる摘まみ片と比較して厚く剛性を備えているため、これを手指で摘まむ際に摘まみやすく引っ張りやすい。また、止着材も摘まみ片の一部として止着材を剥離するときに摘ままれ引っ張られるため、テープ基材のみが引き剥がされて止着材が残されると云う事態が発生することがない。   In the fastening tape of the present invention having the above-described configuration, the fastening material is bonded onto one surface of the tape base material, and the base material tip portion protruding to the tape tip side from the fastening material is integrally formed with the tape base material. Under the premise that it is provided, the base end portion of the tape base material is folded back to the fastening material side to cover a part of the surface of the fastening material and bonded onto the surface of the fastening material, The tape base material because the fastening function stops in the area covered with the tip of the base material and is not fastened to the other fastening material, but is used as a gripping piece when the fastening material is peeled off. A knob having a laminated structure in which the fastening material and the tip of the base material are stacked is formed. Therefore, since the knob piece made of this laminated structure is thicker and more rigid than the knob piece made of the conventional one-layer structure, it is easy to pick and pull when picking it with fingers. Further, since the fastening material is also picked and pulled when the fastening material is peeled off as a part of the knob, a situation may occur in which only the tape base material is peeled off and the fastening material is left. Absent.

基材先端部は、止着材の幅寸法の1/2以下の領域にて止着材の表面を覆うのが好適であり、基材先端部による被覆領域がこれ以上拡大すると、止着材本来の機能である止着機能に支障を来たすおそれがある。   It is preferable that the tip of the base material covers the surface of the fastening material in a region of 1/2 or less of the width dimension of the fastening material. There is a risk that the fixing function, which is the original function, may be hindered.

また、基材先端部は、その一面上に止着機能が設定されている場合にこの止着機能を利用して止着材の表面上に接合されるが、さらに強力な接合を求める場合には、接着、圧着、融着(熱融着を含む)もしくは溶着(超音波による溶着を含む)による固定手段により止着材の表面上に接合される構造としても良い。   In addition, when the fastening function is set on one surface of the base material, the base material is joined on the surface of the fastening material by using this fastening function. May be bonded to the surface of the fastening material by a fixing means such as adhesion, pressure bonding, fusion (including thermal fusion) or welding (including ultrasonic welding).

尚、上記説明では、摘まみ片は、テープ基材、止着材および基材先端部が重ねられた積層構造よりなるとしたが、止着材が面ファスナである場合、面ファスナの多くはシート状の基材部とこの基材部の平面上に設けられた止着片部とを有しているので、これらを別々に数えるとすると、摘まみ片は構成要素ごとにテープ基材、止着材の基材部、止着材の止着片部および基材先端部よりなる4層の積層構造とされる。   In the above description, the knob piece has a laminated structure in which the tape base material, the fastening material, and the tip of the base material are stacked. However, when the fastening material is a surface fastener, most of the surface fasteners are sheets. Since the base plate portion and the fastening piece portion provided on the flat surface of the base portion are counted separately, the knob piece is divided into a tape base material and a base plate for each component. A four-layered structure including a base material portion of the adhesive material, a fastening piece portion of the fastening material and a tip portion of the base material is formed.

本発明の止着テープは、使い捨ておむつに利用される。使い捨ておむつでは、これを使用する者の左右の脇腹部にて前身頃と後身頃とを固定するため、止着テープはおむつの左右で対称に備えられる。   The fastening tape of the present invention is used for disposable diapers. In the disposable diaper, the fastening tape is provided symmetrically on the left and right sides of the diaper in order to fix the front body and the back body at the left and right flank portions of the person using the disposable diaper.

本発明は、以下の効果を奏する。   The present invention has the following effects.

すなわち本発明においては以上説明したように、テープ基材、止着材および基材先端部が積層された積層構造よりなる摘まみ片が形成され、この積層構造よりなる摘まみ片は厚く剛性を備えているため、摘まみやすく引っ張りやすい。また、止着材も摘まみ片の一部とされて止着材の剥離時に摘ままれ引っ張られるため、テープ基材のみが引き剥がされて止着材が残されると云う事態が発生せず、両者が分離することがない。したがって本発明所期の目的どおり、止着材を剥離するときに利用する摘まみ片について、摘まみやすく引っ張りやすく、しかも摘まみ片を摘まんで引っ張ったときにテープ基材が止着材から剥がれてしまうことがない構造の止着テープを提供することができる。   That is, in the present invention, as described above, a knob having a laminated structure in which the tape base material, the fastening material, and the tip of the substrate are laminated is formed, and the knob having the laminated structure is thick and rigid. Because it has, it is easy to pick and pull. In addition, since the fastening material is also a part of the picking piece and is pulled and pulled when the fastening material is peeled off, only the tape base material is peeled off and the fastening material remains, Both are not separated. Therefore, according to the intended purpose of the present invention, the knob base used when peeling the fastening material is easy to pick and pull, and when the pick piece is picked and pulled, the tape substrate is peeled off from the fastening material. It is possible to provide a fastening tape having a structure that does not occur.

また、基材先端部による被覆領域を止着材の幅寸法の1/2以下の領域に設定することにより、止着材本来の機能である止着機能を十分に確保することでき、接着、圧着、融着もしくは溶着による固定手段により基材先端部を止着材の表面上に接合することにより、両者を強固に接合することができる。また、止着材が基材部および止着片部を有する場合には、構成要素ごとに4層に及ぶ積層構造よりなる摘まみ片を設定することができる。   In addition, by setting the area covered by the tip of the base material to an area of 1/2 or less of the width dimension of the fastening material, the fastening function that is the original function of the fastening material can be sufficiently secured, By joining the tip of the base material onto the surface of the fastening material by means of fixing by crimping, fusing or welding, both can be firmly joined. Moreover, when a fastening material has a base material part and a fastening piece part, the knob | pick piece which consists of a laminated structure which extends to four layers for every component can be set.

接合の手段として、基材先端部22bの一面上に止着機能(面ファスナの雌側機能)が設定されている場合にはこの止着機能によって接合することも可能であるが、その有無にかかわらず一層強固な接合とするには、接着剤による接着、下圧による圧着、加熱による融着もしくは超音波による溶着等の手段とするのが適しており、これらの手段によれば、折り返され接合された基材先端部22bが止着材23から剥がれるのを略完全に防止することができる。   As a means for joining, when a fastening function (a female side function of the hook-and-loop fastener) is set on one surface of the base end portion 22b, it is possible to join by this fastening function. Regardless of this, in order to achieve a stronger bond, it is suitable to use means such as adhesive bonding, pressure bonding with lower pressure, welding by heating, or welding by ultrasonic waves. It is possible to substantially completely prevent the bonded base end portion 22b from being peeled off from the fastening material 23.

一方、止着材23は、基材先端部22bによって覆われた領域において止着機能(面ファスナ機能)を停止して相手方の止着材17に止着されないことにより、止着材17,23同士を剥離するときに用いられる摘まみ片25とされている。摘まみ片25は、構成要素ごとにテープ基材22、止着材23の基材部23a、止着材23の止着片部23bおよび基材先端部22bよりなる4層の積層構造とされている(上記したようにテープ基材22およびその一部である基材先端部22bはこれら自体が不織布等による積層構造とされることがあるが、ここではこれらの単層・積層構造にかかわらず、これらを1つの構成要素として数えている)。   On the other hand, the fastening material 23 stops the fastening function (surface fastener function) in the region covered by the base end portion 22b and is not fastened to the other fastening material 17, whereby the fastening materials 17, 23 are used. It is set as the knob 25 used when peeling each other. The knob 25 has a laminated structure of four layers including a tape base material 22, a base material portion 23a of the fastening material 23, a fastening piece portion 23b of the fastening material 23, and a base material tip portion 22b for each component. (As described above, the tape base material 22 and the base material tip portion 22b which is a part of the tape base material 22 itself may have a laminated structure of non-woven fabric or the like. These are counted as one component).

また、基材先端部22bが止着材23の表面の一部を覆う領域の幅寸法wは、止着材23の幅寸法wの1/2以下とされている。したがって止着材23はその全幅のうち、1/2以下の領域で摘まみ片25とされ、残りの部分で止着機能(面ファスナ機能)を発揮する。摘まみ片25を摘まみやすいものとするためには、基材先端部22bが止着材23の表面の一部を覆う領域の幅寸法wはこれを実寸で3mm以上とするのが好ましい。 In addition, the width dimension w 2 of the region where the base end portion 22 b covers a part of the surface of the fastening material 23 is set to ½ or less of the width dimension w 3 of the fastening material 23. Therefore, the fastening material 23 is made into a pinching piece 25 in an area of ½ or less of the entire width, and the fastening function (surface fastener function) is exhibited in the remaining part. In order to be easily seen knob to knob piece 25 is preferably the width w 2 of the regions covering a portion of the surface of the base member distal end portion 22b is fastening member 23 to which the actual size in 3mm or more.

上記構成を備える止着テープ21および使い捨ておむつ1によると、以下の作用効果が発揮される。   According to the fastening tape 21 and the disposable diaper 1 having the above configuration, the following operational effects are exhibited.

すなわち上記構成の止着テープ21においては、テープ基材22の一面上に止着材23が接合されるとともにテープ基材22に止着材23よりもテープ先端側へ突出する基材先端部22bが一体に設けられていると云う前提のもと、テープ基材22の基材先端部22bが止着材23側へ折り返されることにより止着材23の表面の一部を覆うとともに止着材23の表面上に接合され、止着材23が基材先端部22bによって覆われた領域において止着機能を停止して相手方の止着材17に止着されないことにより止着材剥離時の摘まみ片25とされているため、テープ基材22、止着材23および基材先端部22bが重ねられた積層構造よりなる摘まみ片25が形成されている。したがってこの積層構造よりなる摘まみ片25は、従来の1層構造よりなる摘まみ片と比較して厚く剛性を備えているため、これを手指で摘まむ際に摘まみやすく引っ張りやすい。また、止着材23も摘まみ片25の一部として止着材23を剥離するときに摘ままれ引っ張られるため、テープ基材22のみが引き剥がされて止着材23が残されると云う事態が発生することがない。したがって本発明所期の目的どおり、止着材23を剥離するときに利用する摘まみ片25について、摘まみやすく引っ張りやすく、しかも摘まみ片25を摘まんで引っ張ったときにテープ基材22が止着材23から剥がれてしまうことがない構造の止着テープ21を提供することができる。   That is, in the fastening tape 21 having the above-described configuration, the fastening material 23 is joined to one surface of the tape base material 22 and the base material tip portion 22b that protrudes to the tape base material side from the fastening material 23 to the tape base material 22. And the base material tip 22b of the tape base material 22 is folded back to the fastening material 23 side to cover a part of the surface of the fastening material 23 and the fastening material. In the region where the fastening material 23 is bonded to the surface of the base material 23 and is covered with the base end portion 22b, the fastening function is stopped and the fastening material 17 is not fastened to the other fastening material 17 so that the fastening material is removed. Since it is set as the mache piece 25, a knob piece 25 having a laminated structure in which the tape base material 22, the fixing material 23, and the base material tip 22 b are stacked is formed. Therefore, the pick piece 25 made of this laminated structure is thicker and more rigid than the pick piece made of the conventional one-layer structure, so that it is easy to pick and pull when picking it with fingers. Further, since the fastening material 23 is also picked and pulled when the fastening material 23 is peeled off as a part of the tab 25, only the tape base material 22 is peeled off and the fastening material 23 remains. Will not occur. Therefore, as the intended purpose of the present invention, the picking piece 25 used when peeling the fastening material 23 is easy to pick and pull, and when the picking piece 25 is picked and pulled, the tape base material 22 is stopped. The fastening tape 21 having a structure that does not peel off from the dressing 23 can be provided.

また、基材先端部22bによる被覆領域の幅寸法wが止着材23の幅寸法wの1/2以下とされているために、止着材23本来の機能である止着機能を十分に確保することでき、接着、圧着、融着もしくは溶着による固定手段により基材先端部22bが止着材23の表面上に接合されているために、両者22b,23を強固に接合することができる。また、面ファスナの一方の要素を構成する止着材23が基材部23aおよび止着片部23bを有しているために、構成要素ごとに4層に及ぶ積層構造よりなる摘まみ片25が設定され、よって摘まみ片25を比較的厚く硬いものとすることができる。 Further, in order to width w 2 of the coating area by the base member distal end portion 22b is a half or less of the width w 3 of the fastening member 23, the fastening function is fastening material 23 original function Since the base material tip 22b is bonded onto the surface of the fixing material 23 by a fixing means by adhesion, pressure bonding, fusion or welding, the two materials 22b and 23 can be firmly bonded. Can do. Further, since the fastening material 23 constituting one element of the hook-and-loop fastener has the base portion 23a and the fastening piece portion 23b, the knob 25 having a laminated structure of four layers for each component. Accordingly, the knob 25 can be made relatively thick and hard.

また図6に示すように、止着テープ21がその止着材23をもって相手方の止着材17に止着されると、止着材17,23同士の間に基材先端部22bが挟み込まれた状態となるため、この基材先端部23bの厚み分、摘まみ片25は相手方の止着材17の表面に対して持ち上げられた状態となり、角度θをもつこともある。したがって摘まみ片25が持ち上げられた状態で止着され、摘まみ片25の先端が斜め上方へ向いた状態で止着されることもあるため、摘まみ片25はこれを一層摘まみやすい(相手方の止着材17と基材先端部22bとの間に隙間cが形成されるため、この隙間cに手指の先を差し込みやすい)。   As shown in FIG. 6, when the fastening tape 21 is fastened to the other fastening material 17 with the fastening material 23, the base material tip 22 b is sandwiched between the fastening materials 17 and 23. Therefore, the knob 25 is lifted with respect to the surface of the mating fastening member 17 by the thickness of the base end portion 23b, and may have an angle θ. Therefore, since the knob 25 is fixed in a lifted state and may be fixed in a state where the tip of the knob 25 is directed obliquely upward, the knob 25 is more easily picked up (the other party) Since a gap c is formed between the fixing material 17 and the base end portion 22b, it is easy to insert the tip of a finger into the gap c).

更にまた、上記構成の止着テープ21においては、平面台形の突片22aの先端に基材先端部22bが設定されているため、図4に示したようにこの基材先端部22bはこれも平面台形とされ、このように平面台形とされる基材先端部22bが折り返されて止着材23に接合されると、基材先端部22bの両側に位置して平面三角形を呈する止着材23の露出部23cが残され、この露出部23cでは止着材23の止着機能が停止されずに維持されることになる。したがってこの平面三角形の露出部23cは相手方の止着材17に止着可能とされるため、この露出部23cを仮止め部として利用することができる(摘まみ片25は基材先端部22bが折り返された部分で相手方の止着材17に止着されないが、その両側に位置する平面三角形の露出部23cではこの部分に限って相手方の止着材17に止着可能とされる。したがって摘まみ片の全体としては一部に限って相手方の止着材17に止着されるため、摘まみ片25が意図せず折り曲がったり捲り返ったりするのを予防することができる)。   Furthermore, in the fastening tape 21 configured as described above, since the base material tip 22b is set at the tip of the flat trapezoidal protrusion piece 22a, the base material tip 22b is also formed as shown in FIG. When the base material tip portion 22b thus formed into a flat trapezoid is folded back and joined to the fastening material 23, the fastening material is located on both sides of the base material tip portion 22b and presents a planar triangle. 23, the exposed portion 23c is left, and in this exposed portion 23c, the fastening function of the fastening material 23 is maintained without being stopped. Therefore, since the exposed portion 23c of the plane triangle can be fixed to the other fixing material 17, the exposed portion 23c can be used as a temporary fixing portion (the knob piece 25 has the tip end portion 22b of the base material). The folded portion is not fixed to the counterpart fixing material 17, but the flat triangular exposed portions 23c located on both sides thereof can be fixed to the counterpart fixing material 17 only in this portion. Since only a part of the entire piece is fixed to the other material 17, it is possible to prevent the knob 25 from being bent or turned unintentionally).

尚、上記実施例において、テープ基材22の外面(図5(A)(B)における下面)に面ファスナの雌機能を設定する(ループ加工する)と、使い捨ておむつ1において左右一対備えられる止着テープ21,21同士を重ね貼りすることが可能とされる。したがってウエストが細い人でも装着感良く当該使い捨ておむつ1を使用することができる。   In addition, in the said Example, when the female function of a surface fastener is set to the outer surface (the lower surface in FIG. 5 (A) (B)) of the tape base material 22 (loop processing), the disposable diaper 1 will be provided with a pair of left and right. The adhesive tapes 21 and 21 can be laminated and pasted together. Therefore, even a person with a thin waist can use the disposable diaper 1 with good wearing feeling.

また上記実施例では、止着材23による止着機能を面ファスナによる止着機能としたが、止着材23による止着機能はこのほか、粘着剤や粘着テープによる止着機能等であっても良い。   Moreover, in the said Example, although the fastening function by the fastening material 23 was made into the fastening function by a hook-and-loop fastener, the fastening function by the fastening material 23 is a fastening function by an adhesive or an adhesive tape etc. in addition to this. Also good.
