Description

本発明は、特に学童等が使用する鋏に関する。   The present invention particularly relates to a bag used by school children and the like.

鋏本体の刃に被せる鞘状のキャップが付帯した鋏が周知である。この種の鋏では、刃の峰に凹部または凸部を形成する一方、キャップの側壁の内周にこれに対応する凸部または凹部を形成して、両者の凹凸係合を通じてキャップの抜け止めとすることが通例となっている（例えば、下記特許文献を参照）。   A cocoon with a sheath-like cap that covers the blade of the cocoon body is well known. In this type of scissors, a concave portion or a convex portion is formed on the peak of the blade, while a corresponding convex portion or concave portion is formed on the inner periphery of the side wall of the cap, and the cap is prevented from coming off through the engagement of the concave and convex portions. It has become customary (see, for example, the following patent document).

学童等が使用する鋏では、各個に持ち主の名前等を記載しておくことが多い。名前等を記載する、または名前等を記載したラベルを貼付するのに最も適している部位が、キャップの上下面である。しかし、従前の鋏では、キャップを刃に被せたり刃から抜き取ったりする際、キャップの上下面を手指で摘み挟持する必要がある。従って、名前等の記載部位に手指が頻繁に触れてしまい、中長期の使用の結果として名前等の記載が消失、またはラベルが破損する蓋然性が高かった。   Often used for school children, etc., the name of the owner is written on each piece. The most suitable parts for writing a name or the like or affixing a label with a name or the like are the upper and lower surfaces of the cap. However, in the conventional scissors, when the cap is put on the blade or removed from the blade, it is necessary to pinch the upper and lower surfaces of the cap with fingers. Therefore, fingers are frequently touched on a description site such as a name, and there is a high probability that the description of the name or the like is lost or the label is damaged as a result of medium- to long-term use.

実開昭６２−０２３６７９号公報Japanese Utility Model Publication No. 62-023679

以上の問題に初めて着目してなされた本発明は、キャップの両側を挟持して刃を抜き差しすることのできる、使い勝手のよい鋏を提供しようとするものである。   The present invention, which has been made by paying attention to the above problems for the first time, is intended to provide an easy-to-use bag that can be inserted and removed by inserting both sides of the cap.

本発明に係る鋏は、支軸（要）回りに相対回動する刃及び柄の一対を具備する鋏本体と、鋏本体の刃に被せる鞘状のキャップとの組であって、前記鋏本体の刃の刃表（重なり合う一対の刃における、互いに向き合わない外表側）面と、刃の刃表面に対面する前記キャップの周壁面との間に、刃がキャップから抜出することを抑制するための凹凸係合構造を設けており、その凹凸係合構造が、前記支軸よりも刃先（刃における、柄から離れてゆく側の先端、即ち鋏本体の先端）側に所在しており、前記キャップは、離間して対向しそれぞれが前記一対の刃の各刃表面に対面する上壁及び下壁と、上壁及び下壁の側部同士を連接する側壁とを備えており、前記側壁に、前記刃が抜き差しされる開口端から延伸するスリットを切り欠いていることを特徴とする。 The scissors according to the present invention are a set of a scissors main body having a pair of blades and handles that rotate relatively around a support shaft (required), and a sheath-like cap that covers the blades of the scissors main body. In order to prevent the blade from being pulled out of the cap between the surface of the blade (the outer surface side of the pair of overlapping blades that do not face each other) and the peripheral wall of the cap facing the blade surface of the blade The concave-convex engagement structure is provided on the blade edge (the tip of the blade away from the handle, that is, the tip of the heel body) from the support shaft, The cap includes an upper wall and a lower wall that face each other and face each of the blade surfaces of the pair of blades, and a side wall that connects side portions of the upper wall and the lower wall. , that by cutting a slit extending from the open end of the blade is inserted and removed And butterflies.

このようなものであれば、使用者がキャップの上下面ではなく側面を挟持して刃を抜き差しすることができるので、キャップの上下面に記載した名前等が消失したり、キャップの上下面に貼付したラベルが破損したりする不都合が回避される。加えて、支軸とは別個に凹凸係合構造を設けている、つまりはキャップを係留する目的で支軸を利用しないことから、キャップの全長を短縮でき、材料コストの面で有利となる。また。キャップの形状デザインの自由度も増す。   If this is the case, the user can insert and remove the blade while holding the side of the cap instead of the upper and lower surfaces of the cap. The inconvenience that the attached label is damaged is avoided. In addition, since the concave-convex engagement structure is provided separately from the support shaft, that is, the support shaft is not used for the purpose of mooring the cap, the overall length of the cap can be shortened, which is advantageous in terms of material cost. Also. The degree of freedom in designing the shape of the cap is also increased.

加えて、キャップの開口端近傍部位において、上壁と下壁とが互いに離反するように弾性変形して拡開することが可能となる。これにより、鋏本体の使用時に刃からキャップを抜き取りやすくなる。 In addition , in the vicinity of the opening end of the cap, the upper wall and the lower wall can be elastically deformed and expanded so as to be separated from each other. This makes it easier to remove the cap from the blade when using the heel body.

前記側壁に、使用者が手指を掛けることのできる凸形状または凹形状の挟持部を形成してあれば、キャップを操作する使用者に側壁を摘んで挟持するように促すことができる。   If the side wall is provided with a convex or concave pinching portion that allows the user to hang a finger, the user who operates the cap can be urged to pick and hold the side wall.

前記刃に刃表面の方向に突没する段部を設け、前記段部を刃側係合部として利用し、前記キャップの周壁面に設けたキャップ側係合部をこの刃側係合部に係合させるものとすれば、刃裏（重なり合う一対の刃における、互いに向き合う内裏側）に裏すきとなる凹陥を成形する目的、または刃自体の剛性を高める目的で形成した段部をキャップの係留に好適に利用でき、刃の形状を徒に複雑化させずに済む。   The blade is provided with a stepped portion that projects in the direction of the blade surface, the stepped portion is used as the blade side engaging portion, and the cap side engaging portion provided on the peripheral wall surface of the cap is used as the blade side engaging portion. If it is to be engaged, a cap formed on the back of the blade (inner back of the pair of overlapping blades facing each other) for the purpose of forming a concave recess or to increase the rigidity of the blade itself Therefore, the shape of the blade does not need to be complicated.

前記刃にプレス加工を施すことによって前記段部を形成するならば、製造コストの低廉化に資する。   If the step is formed by pressing the blade, it contributes to a reduction in manufacturing cost.

前記段部により、前記刃の刃裏が他方の刃の刃裏から離間していれば、粘着剤が付着している紙片等を切断したときにその粘着剤が刃裏の裏すきに収容されるようになり、刃線部に粘着剤が付着して刃の回動を妨げることがなくなる。   If the blade back of the blade is separated from the blade back of the other blade by the stepped portion, the adhesive is accommodated in the back of the blade when cutting the piece of paper to which the adhesive is attached. This prevents the adhesive from adhering to the blade line portion and preventing the blade from rotating.

前記刃側係合部と前記キャップ側係合部とのうち一方の幅寸が他方の幅寸よりも大きく拡張しているならば、刃側係合部とキャップ側係合部との間に多少の寸法誤差を生じていたとしてもキャップを刃に確実に係留することが可能となる。   If one width dimension of the blade side engaging part and the cap side engaging part is larger than the other width dimension, it is between the blade side engaging part and the cap side engaging part. Even if some dimensional error occurs, the cap can be securely anchored to the blade.

前記一対の刃の双方に前記刃側係合部を設けていれば、キャップを上下裏返しにしたとしても支障なくこれを刃に係留できるようになる。   If the blade side engaging portion is provided on both of the pair of blades, even if the cap is turned upside down, it can be anchored to the blade without any trouble.

本発明によれば、キャップの両側を挟持して刃を抜き差しすることのできる、使い勝手のよい鋏を実現できる。   According to the present invention, it is possible to realize an easy-to-use bag that can insert and remove the blade while holding both sides of the cap.

本発明の一実施形態を、図面を参照して説明する。図１ないし図３に示す本実施形態の鋏は、支軸３回りに相対回動する刃１１、２１及び柄１２、２２の一対１、２を具備する鋏本体Ｈと、鋏本体Ｈの刃１１、１２に被せる鞘状のキャップＣとの組である。   An embodiment of the present invention will be described with reference to the drawings. The scissors according to this embodiment shown in FIGS. 1 to 3 include a scissors body H having a pair 1 and 2 of blades 11, 21 and handles 12, 22 that rotate relatively around the support shaft 3, and a blade of the scissors body H 11 and 12 and a sheath-like cap C.

鋏本体Ｈは、動刃１１に柄１２を取り付けた第一の鋏身１と、静刃２１に柄２２を取り付けた第二の鋏身２とを、支軸３を介して相対回動可能に連結してなる。   The main body H can be rotated relative to the first slimming body 1 with the handle 12 attached to the moving blade 11 and the second slimming body 2 with the handle 22 attached to the stationary blade 21 via the support shaft 3. It is connected to.

動刃１１、静刃２１とも、例えばステンレス鋼板等の金属板を素材とし、全体を一体的にプレス成形することにより作製する。図４に示すように、動刃１１及び静刃２１はそれぞれ、相手方の刃２１、１１（の刃裏面）と摺動する平坦な刃裏面を有する刃線部１１１、２１１と、刃線部１１１、２１１に隣接した段部１１２、２１２とを備える。段部１１２、２１２は、刃線部１１１、２１１との間に段差をなして刃表面方向（換言すれば、刃１１、２１の厚み方向）に立ち上がり、刃１１、２１の峰１１３、２１３まで連続している。段部１１２、２１２の刃元（刃１１、２１における、柄１２、２１に近い側の基部）側の縁端は、柄１２、２２付近に達している。動刃１１及び静刃２１は、その段部１１２、２１２を含めて互いに略相似した形状をなす。   Both the moving blade 11 and the stationary blade 21 are produced by using a metal plate such as a stainless steel plate as a raw material and integrally pressing the whole. As shown in FIG. 4, the moving blade 11 and the stationary blade 21 are blade line portions 111 and 211 having a flat blade back surface that slides against the other blades 21 and 11 (the blade back surface), and the blade line portion 111, respectively. , 211 are adjacent to the step portions 112 and 212. The step portions 112 and 212 are stepped between the blade line portions 111 and 211 and rise in the blade surface direction (in other words, the thickness direction of the blades 11 and 21) to the peaks 113 and 213 of the blades 11 and 21. It is continuous. Edges of the stepped portions 112 and 212 on the blade base (base portions of the blades 11 and 21 on the side close to the handles 12 and 21) reach the vicinity of the handles 12 and 22. The moving blade 11 and the stationary blade 21 have substantially similar shapes including the step portions 112 and 212.

段部１１２、２１２は、刃裏面側から見れば、刃裏面に対して平行な底面を有する凹陥となっており、相手方の刃２１、１１の刃裏面から離間している。この段部１１２、２１２は、粘着テープやクラフトテープ等の、裏面に粘着剤等を塗布したテープ類またはシート類を切断したときに、その粘着剤等が刃１１、１２に粘着して鋏身１、２の動きを悪くする支障を避ける役割を担う。即ち、一旦刃線部１１１、２１１の刃裏面に付着した粘着剤等は、相手方の刃２１、１１の刃線部２１１、１１１によりこそぎ落とされ、段部１１２、２１２内に押し出される。加えて、段部１１２、２１２は、刃１１、２１の剛性を補強する。   When viewed from the blade back surface side, the step portions 112 and 212 are recessed with a bottom surface parallel to the blade back surface, and are separated from the blade back surfaces of the counterpart blades 21 and 11. The stepped portions 112 and 212 are slimmed when the tape or sheet, such as an adhesive tape or craft tape, with adhesive or the like applied to the back surface is cut and the adhesive or the like adheres to the blades 11 and 12. It plays the role of avoiding the obstacles that make the movements 1 and 2 worse. That is, the adhesive once adhered to the blade back surfaces of the blade line portions 111 and 211 is scraped off by the blade line portions 211 and 111 of the counterpart blades 21 and 11 and pushed out into the step portions 112 and 212. In addition, the step portions 112 and 212 reinforce the rigidity of the blades 11 and 21.

動刃１１及び静刃２１に取り付けた柄１２、２２は、硬質の芯材４と、芯材４よりも軟らかい軟質材５とを器材とする。なお、図１ないし図３において、軟質材５を網点にて表す。芯材４は、例えばポリエチレン、ポリスチレン、ポリプロピレンやＡＢＳ樹脂、アクリル酸系樹脂等の熱可塑性樹脂材である。軟質材５は、例えばラバー素材等の弾性のある合成樹脂材である。柄１２、２２は、これら芯材４及び軟質材５を一体的に成形（特に、二色成形）することにより作製する。   The handles 12 and 22 attached to the moving blade 11 and the stationary blade 21 include a hard core material 4 and a soft material 5 softer than the core material 4 as equipment. 1 to 3, the soft material 5 is represented by a halftone dot. The core material 4 is a thermoplastic resin material such as polyethylene, polystyrene, polypropylene, ABS resin, and acrylic resin. The soft material 5 is an elastic synthetic resin material such as a rubber material. The handles 12 and 22 are produced by integrally molding the core material 4 and the soft material 5 (particularly, two-color molding).

動刃１１に取り付ける柄１２は、使用者の親指が挿入される指掛１２１を備える。また、静刃２１に取り付ける柄２２は、使用者の中指、薬指または小指が挿入される指掛２２１を備える。柄１２、２２の本体、即ち刃に取り付く先端部及び指掛環１２１、２２１の外周は、芯材４により形成する。但し、柄２２における、使用者の人差し指が触れ得る部位を除く。加えて、指掛環１２１、２２１の内周における、相手方の柄２２、１２の指掛環２２１、１２１に臨む内側方の部位も芯材４により形成し、芯材４が表出して使用者の指に触れるようにする。   The handle 12 attached to the moving blade 11 includes a finger hook 121 into which a user's thumb is inserted. The handle 22 attached to the stationary blade 21 includes a finger hook 221 into which the user's middle finger, ring finger, or little finger is inserted. The main body of the handles 12 and 22, that is, the tip part attached to the blade and the outer periphery of the finger ring 121 and 221 are formed by the core material 4. However, the portion of the handle 22 that can be touched by the user's index finger is excluded. In addition, on the inner periphery of the finger ring 121, the inner part of the other handle 22, 12 that faces the finger ring 221, 121 of the other party is also formed by the core material 4, and the core material 4 is exposed to the user. Touch your finger.

他方、指掛環１２１、２２１の内周におけるその他の部位、並びに柄２２における使用者の人差し指が触れ得る部位は、軟質材５により形成しており、軟質材５が平面視略Ｃ字型をなしている。この軟質材５は、使用者の手指が接触する接触面部５１、接触面部５１に隣接し周囲よりも薄肉となる有底凹穴部５２、並びに有底凹穴部５２に連なる貫通孔部５３を有している。   On the other hand, the other part of the inner periphery of the finger ring 121, 221 and the part of the handle 22 that can be touched by the user's index finger are formed by the soft material 5, and the soft material 5 is substantially C-shaped in plan view. There is no. The soft material 5 includes a contact surface portion 51 with which a user's finger contacts, a bottomed recessed hole portion 52 adjacent to the contact surface portion 51 and thinner than the surroundings, and a through-hole portion 53 connected to the bottomed recessed hole portion 52. Have.

接触面部５１は、指掛環１２１、２２１の内周における、柄１２、２２の基端と支軸３とを結ぶ直線方向に対向した部位に位置する。有底凹穴部５２及び貫通孔部５３は、各接触面部５１の外周側に隣接している。有底凹穴部５２及び貫通孔部５３は、指掛環１２１、２２１の内周に略沿って拡張している。即ち、有底凹穴部５２及び貫通孔部５３はそれぞれ、略部分円弧状または略部分楕円弧状に形成される。   The contact surface portion 51 is located at a portion facing the linear direction connecting the base ends of the handles 12 and 22 and the support shaft 3 in the inner circumference of the finger ring 121 or 221. The bottomed recessed hole portion 52 and the through hole portion 53 are adjacent to the outer peripheral side of each contact surface portion 51. The bottomed recessed hole 52 and the through hole 53 extend substantially along the inner circumference of the finger ring 121, 221. That is, the bottomed recessed hole portion 52 and the through hole portion 53 are each formed in a substantially partial arc shape or a substantially partial elliptic arc shape.

有底凹穴部５２は、軟質材５の肉厚を周囲よりも薄肉とする有底穴または有底溝である。図５に示すように、本実施形態では、鋏身１、２の表側、裏側からそれぞれ肉盗んで有底凹穴部５２を形成しており、厚み方向の略中間に底５２１がある。   The bottomed recessed hole portion 52 is a bottomed hole or a bottomed groove that makes the thickness of the soft material 5 thinner than the surroundings. As shown in FIG. 5, in the present embodiment, the bottomed recessed hole portion 52 is formed by stealing the meat from the front side and the back side of the slimmings 1 and 2, and the bottom 521 is provided substantially in the middle in the thickness direction.

貫通孔部５３は、ちょうど有底凹穴部５２の底５２１を貫いたような孔または溝である。本実施形態では、貫通孔部５３の拡張方向の両側に有底凹穴部５２が連接している。有底凹穴部５２及び貫通孔部５３は、総体として平面視略三日月型をなす。   The through-hole portion 53 is a hole or a groove that penetrates the bottom 521 of the bottomed recessed hole portion 52. In the present embodiment, the bottomed recessed hole portions 52 are connected to both sides of the through hole portion 53 in the extending direction. The bottomed recessed hole portion 52 and the through-hole portion 53 form a substantially crescent shape in plan view as a whole.

これら有底凹穴部５２及び貫通孔部５３は、接触面部５１の変位ないし変形を促し、接触面部５１に適度な軟らかさを付与する。使用者の手指によって接触面部５１が外周側に圧迫されるとき、有底凹穴部５２の底５２１が圧縮し、及び／または、貫通孔部５３が圧縮して、接触面部５１を外周側へ退避させることができる。また、使用者の手指は、指掛環１２１、２２１に対して斜めに差し入れられることが多い。その際には、接触面部５１が有底凹穴部５２の底５２１を支点として斜めに傾くことができる。いわば、指掛環１２１、２２１が傾斜して（または、捻れ）、使用者の手指の抜き差しを容易にする。   The bottomed recessed hole portion 52 and the through-hole portion 53 promote displacement or deformation of the contact surface portion 51 and impart appropriate softness to the contact surface portion 51. When the contact surface portion 51 is pressed to the outer peripheral side by the user's finger, the bottom 521 of the bottomed recessed hole portion 52 is compressed and / or the through-hole portion 53 is compressed, and the contact surface portion 51 is moved to the outer peripheral side. Can be evacuated. Also, the user's fingers are often inserted obliquely with respect to the finger ring 121, 221. In that case, the contact surface portion 51 can be inclined obliquely with the bottom 521 of the bottomed recessed hole portion 52 as a fulcrum. In other words, the finger ring 121, 221 is inclined (or twisted) to facilitate insertion and removal of the user's fingers.

支軸３は、ねじ、かしめ等を主体とし、柄１２、２２の先端部を刃１１、２１もろとも貫通する。支軸３の軸端部は、その周辺部位よりも突出していない。   The support shaft 3 is mainly composed of screws, caulking, and the like, and penetrates the tips of the handles 12 and 22 together with the blades 11 and 21. The shaft end portion of the support shaft 3 does not protrude beyond its peripheral portion.

キャップＣは、鋏本体Ｈの非使用時に刃１１、２１に被せておく部材であって、鞘状の周壁、即ち、離間して対向する上壁６及び下壁７と、上壁６及び下壁７の側部同士を連接する側壁８、９とを備えている。キャップＣの先端部には、内外を連通する貫通孔０を穿ってある。   The cap C is a member that covers the blades 11 and 21 when the heel body H is not used, and is a sheath-like peripheral wall, that is, the upper wall 6 and the lower wall 7 that face each other at a distance, and the upper wall 6 and the lower wall. Side walls 8 and 9 connecting the side portions of the wall 7 are provided. A through hole 0 that communicates the inside and the outside is formed at the tip of the cap C.

キャップＣを刃１１、２１に被せたとき、上壁６及び下壁７は、それぞれが刃１１、２１の各刃表面に対面する。左右の側壁８、９は、それぞれが刃１１、２１の峰に対面する。このキャップＣは、例えばポリエチレン、ポリスチレン、ポリプロピレンやＡＢＳ樹脂、アクリル酸系樹脂等の硬質樹脂成形品である。   When the cap C is put on the blades 11 and 21, the upper wall 6 and the lower wall 7 face the blade surfaces of the blades 11 and 21, respectively. The left and right side walls 8 and 9 face the peaks of the blades 11 and 21, respectively. The cap C is, for example, a hard resin molded product such as polyethylene, polystyrene, polypropylene, ABS resin, or acrylic resin.

キャップＣの上壁６の表面には、鋏の持ち主の名前等を記載する、または名前等を記載したラベルを貼付するのに適した記載部６２が存在する。記載部６２は、上壁６の表面よりも若干だけ凹んでいる。   On the surface of the upper wall 6 of the cap C, there is a description section 62 suitable for describing the name of the owner of the bag or for attaching a label describing the name or the like. The description portion 62 is slightly recessed from the surface of the upper wall 6.

キャップＣの側壁８、９には、刃１１、２１が抜き差しされる開口端から先方に向かって伸びるスリット８１、９１を切り欠いている。また、側壁８、９の中間部に、使用者が手指を掛けることのできる挟持部８２、９２を形成してある。挟持部８２、９２は、側方に突出した凸形状をなす。   The side walls 8 and 9 of the cap C are notched with slits 81 and 91 extending from the open end where the blades 11 and 21 are inserted and removed. In addition, sandwiching portions 82 and 92 on which the user can hang fingers are formed in the intermediate portions of the side walls 8 and 9. The sandwiching portions 82 and 92 have a convex shape protruding sideways.

しかして、本実施形態では、刃１１、２１の刃表面と、刃１１、２１の刃表面に対面するキャップＣの上下壁６、７の内面との間に、凹凸係合構造を設けている。   Thus, in the present embodiment, an uneven engagement structure is provided between the blade surfaces of the blades 11 and 21 and the inner surfaces of the upper and lower walls 6 and 7 of the cap C facing the blade surfaces of the blades 11 and 21. .

凹凸係合構造は、刃側係合部１１２、２１２と、刃側係合部１１２、２１２に係合するキャップ側係合部６１、７１とを要素とする。刃側係合部は、段部１１２、２１２、特にその刃元側の縁端である。これに対し、キャップ側係合部は、図６及び図７に示すように、上壁６及び下壁７における開口端近傍部位の内面から、互いに相寄る方向に突出した突起６１、７１である。刃側係合部１１２、２１２の幅寸（刃１１、２１の刃先と刃元とを結ぶ直線に対して交差する方向の寸法）は、キャップ側係合部６１、７１の幅寸よりも大きく拡張している。   The concavo-convex engagement structure includes the blade side engaging portions 112 and 212 and the cap side engaging portions 61 and 71 engaged with the blade side engaging portions 112 and 212 as elements. The blade side engaging portion is the edge of the stepped portions 112 and 212, particularly the blade base side. On the other hand, as shown in FIGS. 6 and 7, the cap-side engaging portions are protrusions 61 and 71 that protrude from the inner surfaces of the upper wall 6 and the lower wall 7 in the vicinity of the open ends in a direction close to each other. . The width dimension of the blade side engaging portions 112 and 212 (the dimension in the direction intersecting the straight line connecting the blade tips of the blades 11 and 21 and the blade base) is larger than the width dimension of the cap side engaging portions 61 and 71.

図７に示しているように、鋏本体Ｈの刃１１、２１にキャップＣを被せ、その開口端を柄１２、２２の終端に当接ないし極近接させたとき、刃側係合部１１２、２１２とキャップ側係合部６１、７１とが係合し、キャップＣを刃１１、２１に係留する。   As shown in FIG. 7, when the caps 11 are put on the blades 11 and 21 of the scissors body H and the opening ends thereof are brought into contact with or in close proximity to the terminal ends of the handles 12 and 22, the blade side engaging portions 112, 212 and the cap side engaging portions 61 and 71 are engaged, and the cap C is anchored to the blades 11 and 21.

本実施形態によれば、支軸３回りに相対回動する刃１１、２１及び柄１２、２２の一対を具備する鋏本体Ｈと、鋏本体Ｈの刃１１、２１に被せる鞘状のキャップＣとの組であって、前記鋏本体Ｈの刃１１、２１の刃表面と、刃１１、２１の刃表面に対面する前記キャップＣの周壁面６、７との間に、刃１１、２１がキャップＣから抜出することを抑制するための凹凸係合構造を設けており、その凹凸係合構造が、前記支軸３よりも刃先側に所在しているため、使用者がキャップＣの側面を挟持して刃１１、２１を抜き差しすることができ、キャップＣの上下面に記載した名前等が消失したり、キャップＣの上下面に貼付したラベルが破損したりする不都合が回避される。加えて、支軸３とは別個に凹凸係合構造を設けている、つまりはキャップＣを係留する目的で支軸３を利用しないことから、キャップＣの全長を短縮でき、材料コストの面で有利となる。また。キャップＣの形状デザインの自由度も増す。   According to the present embodiment, the heel body H having a pair of blades 11, 21 and handles 12, 22 that rotate relative to the support shaft 3, and a sheath-like cap C that covers the blades 11, 21 of the heel body H The blades 11, 21 are between the blade surfaces of the blades 11, 21 of the main body H and the peripheral wall surfaces 6, 7 of the cap C facing the blade surfaces of the blades 11, 21. A concave / convex engagement structure is provided for preventing the cap C from being pulled out, and the concave / convex engagement structure is located closer to the blade edge than the support shaft 3. The blades 11 and 21 can be inserted / removed by holding the blade, and the inconvenience that the names and the like written on the upper and lower surfaces of the cap C are lost or the labels attached to the upper and lower surfaces of the cap C are broken can be avoided. In addition, since the uneven engagement structure is provided separately from the support shaft 3, that is, the support shaft 3 is not used for the purpose of mooring the cap C, the total length of the cap C can be shortened, and in terms of material cost It will be advantageous. Also. The degree of freedom in the shape design of the cap C is also increased.

前記キャップＣが、離間して対向しそれぞれが前記一対の刃１１、２１の各刃表面に対面する上壁６及び下壁７と、上壁６及び下壁７の側部同士を連接する側壁８、９とを備えており、前記側壁８、９に、前記刃１１、２１が抜き差しされる開口端から延伸するスリット８１、９１を切り欠いているため、キャップＣの開口端近傍部位において、上壁６と下壁７とが互いに離反するように弾性変形して拡開することが可能となる。これにより、鋏本体Ｈの使用時に刃１１、２１からキャップＣを抜き取りやすくなる。   The cap C is spaced apart and faces the upper wall 6 and the lower wall 7 facing the respective blade surfaces of the pair of blades 11 and 21, and the side walls connecting the side portions of the upper wall 6 and the lower wall 7 to each other. 8 and 9, and the side walls 8 and 9 are notched with slits 81 and 91 extending from the opening end where the blades 11 and 21 are inserted and removed, in the vicinity of the opening end of the cap C, The upper wall 6 and the lower wall 7 can be elastically deformed and expanded so as to be separated from each other. This makes it easier to remove the cap C from the blades 11 and 21 when using the bag main body H.

前記側壁８、９に、使用者が手指を掛けることのできる挟持部８２、９２を形成してあるため、キャップＣを操作する使用者に側壁８、９を摘んで挟持するように促すことができる。   Since the holding portions 82 and 92 on which the user can place fingers are formed on the side walls 8 and 9, the user who operates the cap C is urged to pick and hold the side walls 8 and 9. it can.

前記刃１１、２１に刃表面の方向に突没する段部１１２、２１２を設け、前記段部１１２、２１２を刃側係合部として利用し、前記キャップＣの周壁面に設けたキャップ側係合部６１、７１をこの刃側係合部１１２、２１２に係合させるものとしているため、刃裏に裏すきとなる凹陥を成形する目的及び／または刃１１、２１自体の剛性を高める目的で形成した段部１１２、２１２をキャップＣの係留に好適に利用でき、刃１１、２１の形状を徒に複雑化させずに済む。   The blades 11 and 21 are provided with step portions 112 and 212 projecting in the direction of the blade surface, and the step portions 112 and 212 are used as blade side engaging portions, and the cap side engagement provided on the peripheral wall surface of the cap C. Since the joint portions 61 and 71 are engaged with the blade side engaging portions 112 and 212, for the purpose of forming a recess that serves as a backing on the blade back and / or for the purpose of increasing the rigidity of the blades 11 and 21 themselves. The formed step portions 112 and 212 can be suitably used for mooring the cap C, and the shapes of the blades 11 and 21 do not need to be complicated.

前記刃１１、２１にプレス加工を施すことによって前記段部１１２、２１２を形成しているため、製造コストの低廉化に資する。   Since the stepped portions 112 and 212 are formed by pressing the blades 11 and 21, the manufacturing cost is reduced.

前記段部１１２、２１２により、前記刃１１、２１の刃裏が他方の刃２１、１１の刃裏から離間しているため、粘着剤が付着している紙片等を切断したときにその粘着剤が刃裏の裏すきに収容されるようになり、刃線部１１１、２１１に粘着剤が付着して刃１１、２１の回動を妨げることがなくなる。   Since the blades of the blades 11 and 21 are separated from the blades of the other blades 21 and 11 by the stepped portions 112 and 212, the pressure-sensitive adhesive when the piece of paper to which the adhesive is attached is cut. Is housed in the back of the blade, and the adhesive does not adhere to the blade line portions 111 and 211, thereby preventing the blades 11 and 21 from rotating.

前記刃側係合部１１２、２１２の幅寸が前記キャップ側係合部６１、７１の幅寸よりも大きく拡張しているため、刃側係合部１１２、２１２とキャップ側係合部との間に多少の寸法誤差を生じていたとしてもキャップＣを刃１１、２１に確実に係留することが可能となる。   Since the width dimension of the blade side engaging parts 112 and 212 is larger than the width dimension of the cap side engaging parts 61 and 71, the blade side engaging parts 112 and 212 and the cap side engaging part Even if some dimensional error occurs in the meantime, the cap C can be securely anchored to the blades 11 and 21.

前記一対の刃１１、２１の双方に前記刃側係合部１１２、２１２を設けているため、キャップＣを上下裏返しにしたとしても支障なくこれを刃１１、２１に係留できる。   Since the blade side engaging portions 112 and 212 are provided on both the pair of blades 11 and 21, even if the cap C is turned upside down, it can be moored to the blades 11 and 21 without any problem.
