Definitions
- the present invention relates to an absorbent pad used for absorbing excrement such as urine and menstrual blood.
- an absorption pad for the purpose of urine absorption on the inner surface in consideration of replacement frequency (for example, see Patent Document 1 or 2).
- attaching the absorption pad to the inner surface of the underwear for lower body is also performed.
- an absorbent pad an absorbent body is interposed between the liquid-impervious sheet and the liquid-permeable top sheet, and the liquid-impervious sheet and the liquid-permeable top sheet are more than the ventral end of the absorbent body. It has a structure in which the front end flap part and the rear end flap part, which are extended to the back side from the ventral side and the back side, respectively, are formed, and the absorbent body does not exist by these extended parts.
- the absorbent pad having such a structure an adhesive, hook tape of a hook-and-loop fastener (mechanical fastener), etc. are attached to the back side in order to prevent displacement at the time of wearing, and through these fastening means It is common to attach to the inner surface of a diaper or lower body underwear.
- the fastening means using the hook tape has an advantage that the fastening ability does not decrease even if the fastening and peeling are repeated frequently.
- a main problem of the present invention is to provide an absorbent pad that can be easily peeled off from a diaper or lower body underwear without damaging the diaper or lower body underwear at the time of replacement, while having sufficient slip prevention performance. .

Then, as shown in FIG. 16B, first, the adhesion surface between the temporary fixing portion 33 and the back surface side of the extending portion 31a is separated. Subsequently, as illustrated in FIG. 16C, the extension portion 31 a of the fastening panel 31 is shaped so as to be lifted from the folded portion 31 c side with respect to the liquid-permeable top sheet 2, and the extension portion 31 a. Is substantially scraped off from the folded portion 31c side. That is, since the force is applied to the fastening surface of the hook tape 32 in the vertical direction without applying a force in the shearing direction, the fastening surface can be separated with a weak force.
- the fastening surface of the diaper or lower body underwear is not damaged, and it is not necessary to weaken the adhesive force of the hook tape 32.
- the hook tape 32 is not displaced from the fastening surface by the movement or peeled off.
- the extension part 31a is adhere
- the fastening panel 31 can also be formed with a short length in the width direction as shown in FIG.
- the hook tape 32 is peeled off from the back side to the ventral side on the fastening surface of the hook tape 32 and the liquid-permeable top sheet 2. Therefore, since the number of hook-shaped projections separated from the liquid-permeable top sheet 2 at a time is reduced, it is easy to peel off.
- fastening panels 31 may be provided at a plurality of locations. As shown in FIG. 18, by providing each in the vicinity of both ends on the back side, the total length in the width direction of the hook tape 32 can be shortened, and it becomes easy to peel off as in the embodiment of FIG. Peeling from the back side ends can be suitably prevented. Further, by providing the fastening panel 31 near the center of the absorbent pad 200, it is possible to prevent the shift near the center of the absorbent pad 200.
- the hook-like protrusion F is placed on the base sheet 32 s of the hook tape 32 so that the tip of the hook-like protrusion F of the hook tape 32 faces forward.
- it can be formed to be inclined at an angle of ⁇ 1 .
- the absorbent pad 200 according to the present invention is in the product state, even if the fastening panel 31 is folded back at the folded portion 31c and the back surface side of the extended portion 31a is bonded to the temporary fastening portion 33.
- the wearing panel 31 is unfolded, and when used, the user turns the fastening panel 31 back at the folded portion 31c and attaches the back side of the extended portion 31a to the temporary fastening portion 33, and then stops the diaper or lower body underwear. You may wear it.
- the protective sheet of the temporary fixing portion 33 is not necessary, so the number of parts is small. Therefore, manufacturing cost can be reduced.
- the present invention is applicable to sanitary napkins as well as those used in combination with disposable diapers as long as they are absorbent pads.

Abstract
Description
このような吸収パッドは、不透液性シートと透液性トップシートとの間に吸収体が介在されるとともに、不透液性シートおよび透液性トップシートが吸収体の腹側端よりも腹側及び背側よりも背側にそれぞれ延出され、これら延出部分により吸収体の存在しない前エンドフラップ部及び後エンドフラップ部がそれぞれ形成された構造を有しており、股間から腹側に延在する腹側部分と、股間から背側に延在する背側部分とを有している。
また、このような構造を有する吸収パッドにおいては、装着時のズレ防止のため、裏面側に粘着剤や面ファスナー(メカニカルファスナー)のフックテープ等が取り付けられており、これらの止着手段を介しておむつ又は下半身用肌着の内面に止着することが一般的となっている。その中でも、フックテープを用いた止着手段は、止着及び剥離を度々繰り返しても止着能力が低下しないという利点を有している。
吸収パッドの交換方法は様々であるが、着用者自身又は介助者が使用済の吸収パッドを新しいものに交換する場合、おむつ又は下半身用肌着をある程度までズリ下ろし、おむつ又は下半身用肌着から吸収パッドを剥がすといった方法が一般的である。
また、このような交換作業の煩雑さゆえ、おむつ又は下半身用肌着を殆ど下ろすことなく、吸収パッドの腹側を摘んで引っ張り出すことによって使用済の吸収パッドを除去することも行われている。しかし、従来の吸収パッドにおいてこのような交換方法を採用した場合、吸収パッドを引っ張り出す際に、フックテープとおむつ又は下半身用肌着との止着面に作用する力は殆どが剪断力となるため、フックテープの性質上非常に剥がれにくく、剥がすのに強い力が必要であった。また、剥がれたとしても、おむつ又は下半身用肌着に対して強い力がかかるためフックテープの突起によっておむつ又は下半身用肌着の繊維が傷んでしまうという問題があった。かといって、剥がす際に必要な力を弱く抑えるためにフックテープの接着力を弱くするのは、ズレ止め性能が低下してしまうため好ましい解決策とはいえない。
そこで、本発明の主たる課題は、十分なズレ止め性能を有しながらも、交換時には、おむつ又は下半身用肌着を傷つけることなく、おむつ又は下半身用肌着から容易に剥がれる吸収パッドを提供することにある。
<請求項1記載の発明>
股間から腹側に延在する腹側部分と、股間から背側に延在する背側部分とを有する吸収パッドにおいて、
前記吸収パッドの裏面に固定された基端部と、この基端部の後縁から延出する部分であって且つ前記吸収パッドの裏面に固定されていない延出部と、この延出部内における前記吸収パッドに対する固定面と同じ側の面に固定されるとともに、この固定面の反対面にフック状突起を多数有するフックテープと、を有する止着パネルを備えており、
この止着パネルの延出部が、前記基端部との境界から前記フックテープの一部までの範囲内で前側に折り返され、この折り返し部分の外面に前記フックテープのフック状突起を有する面が露出するように構成されている、
ことを特徴とする吸収パッド。
本発明の吸収パッドを装着する際には、止着パネルを折り返した状態で、折り返し部分の外面に露出するフックテープのフック状突起をおむつ又は下半身用肌着の内面に止着する。このような装着状態から、交換に際して、吸収パッドの前端部を持って腹側から引っ張り出すようにすると、止着パネルの折り返し部分がフックテープによる止着部分を含めて、基端部側の部分から順に捲り取られるようにして剥がされる。この際、フックテープの止着面には剪断方向に力が作用せず、剪断方向と交差する方向に力が作用するため、より弱い力で円滑にフックテープを止着面から剥離することができる。よって、交換の際におむつ又は下半身用肌着をさほどズリ下ろすことなく容易に吸収パッドを剥離することができるようになる。また、止着面に強い剪断力を作用させずに済むため、おむつ又は下半身用肌着の止着面を傷つけることがない。さらに、フックテープの接着力を弱くする必要がないためズレ止め性能を低下させることもない。
前記折り返された状態で、前記折り返し部分がその対向面に取り外し可能なように仮止めされている、請求項1記載の吸収パッド。
止着パネルにおける折り返し部分が対向面に固定されていないと、使用に際して、吸収パッドとおむつ等との止着は可能であるが、止着パネルの折り返し部分に対して吸収パッドがずれるおそれがある。よって、本項記載のように、折り返し部分をその対向面に取り外し可能なように仮止めし、使用時の吸収パッドのずれを防止するのが好ましい。吸収パッドの交換の際には、止着パネルの折り返し部分が捲れるのに伴って仮止めが外れるため、前述した本発明の作用効果が損なわれることもない。
前記止着パネルが前記背側部分に設けられている、請求項1または請求項2記載の吸収パッド。
本項記載のように、本発明に係る止着パネルは、特に手が届きにくい背側に設けるのが好適である。
前記止着パネルの折り返し部分を後側に展開した状態で、前記フックテープのフック状突起を有する面全体が、吸収パッドの裏面と対向し、身体側に露出しないように構成されている、請求項1~請求項3のいずれか1項に記載の吸収パッド。
本項記載のように構成されていると、吸収パッドを交換する際に、止着パネルの折り返し部分が捲れることにより、止着パネル全体が展開しても、フックテープの全体が身体側に露出しないため、硬い素材であるフックテープによって装着者の肌を傷つけてしまうといった事態を防止することができる。
前記フック状突起は前記延出部の先端側に傾斜している、請求項1~請求項4のいずれか1項に記載の吸収パッド。
止着パネルが背側部分に設けられている形態において、フックテープのフック状突起がこのように傾斜していると、吸収パッドの背側部分が股間側にずれ落ちようとするとフック状突起が止着面に深く突き刺さるようになるため、このようなずれ落ち(特に背側部分が排泄物の吸収により重くなるとこのようなずれが発生し易い)が発生し難くなる。しかも、本発明では、吸収パッドの交換時において、吸収パッドの前端部を持って腹側から引っ張り出すようにすると、止着パネルの折り返し部分が基端部側の部分から順に捲り取られるようにして剥がされるため、本項記載のように傾斜したフック状突起を採用しても、剥離の容易性が損なわれない。
図1~図6は、本発明に係るテープ式使い捨ておむつの一例100を示しており、この使い捨ておむつ100は、外面に外装シート12が積層された不透液性バックシート1の内面と、透液性トップシート2との間に、吸収体3が介在されているものである。
図7~15は、本発明に係る吸収パッド例200を示している。この吸収パッド200は、紙おむつ100の内面に敷いて使用されることを想定したものであり、股間部C2と、その前後両側に延在する腹側(前側)部分F2及び背側(後側)部分B2とを有するものである。各部の寸法は適宜定めることができ、例えば、物品全長(前後方向長さ)L1は350~700mm程度、全幅W1は130~400mm程度(ただし、おむつの吸収面の幅より狭い)とすることができ、この場合における股間部C2の前後方向長さは10~150mm程度、腹側部分F2の前後方向長さは50~350mm程度、及び背側部分B2の前後方向長さは50~350mm程度とすることができる。
次に、本発明における他の実施形態について添付図面を参照しつつ詳説する。
止着パネル31は、図17のように幅方向長さを短く形成することもできる。このように形成すると、吸収パッド200のおむつ100からの分離時に、フックテープ32と透液性トップシート2との止着面において、フックテープ32が背側から腹側にかけて捲り剥がすような剥がし方となるため、透液性トップシート2から一度に分離するフック状突起の数が少なくなるため剥がし易くなる。
