Description

本発明は、合成樹脂製のラップフィルムまたはアルミホイルや台所用の紙シートなど、ロール状に巻かれた各種シートを詰め替え可能に収容し、前記各種シートを引き出して切断することのできる詰め替え用のラップフィルムケースに関する。   The present invention accommodates various sheets wound in a roll shape, such as a synthetic resin wrap film or aluminum foil or a kitchen paper sheet, so that the sheets can be refilled, and the various sheets can be pulled out and cut. It relates to a wrap film case.

従来、ラップカッターとして、押しボタンに当接して取り付けられた切断刃を防護カバーで覆った蓋体と板バネを内蔵したフィルム案内板係止部を有する本体を、丁番を介して接続し、粘着部を設けた曲面を有するフィルム案内板を中蓋として本体に収容されたフィルムロールの円周面の約４分の１を覆い、その前後にフィルム引き出し口と切断刃貫入孔を設けたものが開示される（特許文献１参照）。これは硬軟いずれのフィルムでも確実に切れる安定した性能と耐久性を備え、安全で使いやすく、コンパクトでデザイン性に優れたラップカッターを得、ひいては使い捨ての紙容器を廃した安価な詰め替え用ロールの供給を促し、資源の節約とゴミの減量と消費者の利益に寄与する、とされる。   Conventionally, as a wrap cutter, a lid body in which a cutting blade attached in contact with a push button is covered with a protective cover, and a main body having a film guide plate locking portion incorporating a leaf spring are connected via a hinge, Covering about one-fourth of the circumferential surface of the film roll housed in the main body with a curved film guide plate provided with an adhesive part as the inner lid, and provided with a film outlet and a cutting blade penetration hole before and after that Is disclosed (see Patent Document 1). This is a wrap cutter with stable performance and durability that can be cut reliably with either hard or soft film, safe and easy to use, compact and excellent in design, and as a result, an inexpensive refill roll that has been discarded disposable paper containers. It promotes supply and contributes to resource saving, garbage reduction and consumer benefits.

また従来、ラップフィルムの箱として、合成樹脂製の収納部、側蓋、嵌合壁、鋸刃部を備えた上蓋及びラップフィルム固定用円筒よりなる組立可能な構造であり、前記ラップフィルム固定用円筒にラップフィルム巻取り治具により巻取り径を拡大し紙管の無いラップフィルムの筒を差し込んだラップフィルム箱が開示される（特許文献２参照）。これは全体が合成樹脂製で、ラップフィルムを詰め替え繰返し使用できるので資源、費用の削減が可能であり、紙管の無いラップフィルムを使用することにより資源・費用の削減が可能であるのみならず、折り畳むことによって輸送・保管の費用削減が可能となる、とされる。   Conventionally, as a wrap film box, it can be assembled from a synthetic resin storage part, a side cover, a fitting wall, a top cover provided with a saw blade part, and a wrap film fixing cylinder. A wrap film box is disclosed in which a winding diameter is enlarged by a wrap film winding jig and a cylinder of a wrap film without a paper tube is inserted into a cylinder (see Patent Document 2). This is entirely made of synthetic resin and can be refilled and used repeatedly, so resources and costs can be reduced. Not only can resources and costs be reduced by using wrap films without paper tubes. The cost of transportation and storage can be reduced by folding.

しかしながら上記従来のラップフィルムケースは、切断のためにラップフィルムをある程度の長さまで引き出す必要があり、また引き出したラップフィルムの切断作業が容易とはいえず、切断不良によって不経済を生ずる可能性があった。特に片手がふさがった状態での使用に困難性を有していた。   However, the conventional wrap film case needs to pull out the wrap film to a certain length for cutting, and the cutting operation of the drawn wrap film is not easy, and may cause uneconomical due to poor cutting. there were. In particular, it was difficult to use when one hand was blocked.

そこで本発明は、切断のためのラップフィルムの引き出し量を抑え、また引き出したラップフィルムの切断作業が比較的容易であり、また場合によって不要に張り付きにくく、さらに切断不良を起こしにくいラップフィルムケースを提供することを課題とする。   Accordingly, the present invention provides a wrap film case that suppresses the amount of wrap film that is pulled out for cutting, is relatively easy to cut the wrap film that is pulled out, and does not stick unnecessarily in some cases, and that does not cause cutting defects. The issue is to provide.

上記課題を解決すべく本発明では下記（１）〜（５）の手段を講じている。
（１）本発明のラップフィルムケースは、
ロール状に巻回されたフィルムシートｆを収容する収容部を有し、上方に開口した本体下部１と、
本体下部１の前記開口を上覆するように配置され、前記フィルムシートｆの軸と並行軸のまま移動することで開閉可能に覆う本体上部２と、
本体上部２内の収容位置と、本体上部２の下縁からそれ自身の刃部が突出した突出位置との間を移動可能に収容支持された切断上刃２０と、
フィルムシートのロール両端に挿入されたままフィルムシートｆと共に収容部に収容される軸受け８と、を具備してなり、
本体上部２が回転移動して前記開口を閉じた第二閉口状態ｓ２において、切断上刃２０が前記収容位置から突出位置へ移動することで、収容部から引き出されたフィルムシートを切断するものであり、
前記収容部の開口下部に、弾性ゴムからなる上端面を有した受け座１１が形成され、収容部から引き出したフィルムシートが受け座１１に一時的に張り付いて固定されることを特徴とする。 In order to solve the above problems, the present invention employs the following means (1) to (5).
(1) The wrap film case of the present invention is
A main body lower part 1 having an accommodating part for accommodating a film sheet f wound in a roll shape, and opened upward;
A main body upper part 2 which is arranged so as to cover the opening of the lower part of the main body 1 and which can be opened and closed by moving in parallel with the axis of the film sheet f;
A cutting upper blade 20 that is housed and supported so as to be movable between a housing position in the main body upper portion 2 and a protruding position in which the blade portion of the main body 2 protrudes from the lower edge;
A bearing 8 accommodated in the accommodating portion together with the film sheet f while being inserted at both ends of the roll of the film sheet,
In the second closed state s2 in which the upper body 2 rotates and closes the opening, the cutting upper blade 20 moves from the storage position to the protruding position, thereby cutting the film sheet drawn from the storage portion. Yes,
A receiving seat 11 having an upper end surface made of elastic rubber is formed in the lower portion of the opening of the housing portion, and a film sheet pulled out from the housing portion is temporarily stuck and fixed to the receiving seat 11. .

（２）受け座１１は、切断上刃２０の刃先の入り込む隙間を設けて離間配置し、離間した各内面に外刃１０Ａと内刃１０Ｂを対向配置し、
外刃１０Ａと内刃１０Ｂが受け座１１によって外方から弾性支持されることで、
切断上刃２０が前記収容位置から突出位置へ移動することで、外刃１０Ａと内刃１０Ｂそれぞれと切断上刃２０のせん断力によって、受け座１１上に引き出したフィルムシートを切断することが好ましい。 (2) The receiving seat 11 is spaced apart by providing a gap into which the cutting edge of the cutting upper blade 20 enters, and the outer blade 10A and the inner blade 10B are disposed opposite to each separated inner surface,
The outer blade 10A and the inner blade 10B are elastically supported from the outside by the receiving seat 11,
It is preferable to cut the film sheet pulled out on the receiving seat 11 by the shearing force of the outer blade 10A, the inner blade 10B, and the cutting upper blade 20 by the cutting upper blade 20 moving from the housing position to the protruding position. .

（３）本体上部２の上部に、切断上刃２０と上部連接したスイッチ部２３が露出し、
切断上刃２０は、両端が本体上部２内に軸支された支持アーム２５の他端にて回動可能に支持され、また本体上部２内の側方から張設された側方弾性材によって弾性支持されてなり、スイッチ部２３を下方へ押すことで切断上刃２０が前記収容位置から突出位置へ正面視斜め下方に回動し、弾性反力によって突出位置から再び収容位置へ正面視斜め上方に自動収容されることが好ましい。 (3) On the upper part of the main body upper part 2, the switch part 23 connected to the upper cutting blade 20 and the upper part is exposed,
The cutting upper blade 20 is rotatably supported at the other end of a support arm 25 that is pivotally supported in the upper part 2 of the main body, and is formed by a side elastic member stretched from the side in the upper part 2 of the main body. It is elastically supported, and when the switch part 23 is pushed downward, the cutting upper blade 20 is rotated obliquely downward from the accommodation position to the projecting position in the front view, and obliquely seen from the projecting position to the accommodation position again by the elastic reaction force. It is preferable to automatically accommodate upward.

（４）前記軸受け８は、ロール状のフィルムシートの両端に挿入される挿入軸８３と、挿入軸８３の周囲の複数位置に張り付けられた固定板８１と、挿入軸８３の先端にて拡径したフランジ板８２とを具備し、フィルムシートが収容部内から引き出され、ロール状部が回転するのに伴って、この固定板８１がフィルムシートのロール内面に所定の回転抵抗を与え、フランジ板８２が収容部内面に所定の回転抵抗を与えることが好ましい。 (4) The bearing 8 has an insertion shaft 83 inserted at both ends of the roll-shaped film sheet, a fixing plate 81 attached to a plurality of positions around the insertion shaft 83, and a diameter expansion at the tip of the insertion shaft 83. The fixing plate 81 gives a predetermined rotational resistance to the inner surface of the roll of the film sheet as the film sheet is pulled out from the accommodating portion and the roll-shaped portion rotates, and the flange plate 82 is provided. It is preferable to provide a predetermined rotational resistance to the inner surface of the housing portion.

いずれの実施例においても、本発明のラップフィルムケースは、フィルムシートｆをロール軸回りに巻回したフィルムロールＦを収容する収容部を有して上方に開口した本体下部１と、
本体下部１の前記開口を覆い、本体下部１の開口前縁との間に、収容したフィルムロールＦからフィルムシートｆを引き出す引き出し口７を開閉可能に形成する本体上部２と、
本体上部２内に収容され、それ自身の刃部が収容された収容位置（Ｓ１）と、本体上部２の下縁からそれ自身の刃部が突出した突出位置（Ｓ２）との間を移動可能に支持された切断上刃２０と、
フィルムシートのロール両端に挿入され、フィルムシートｆと共に本体下部１の収容部に収容される軸受け８と、を具備してなる。 In any embodiment, the wrap film case of the present invention has a main body lower portion 1 having an accommodating portion for accommodating a film roll F obtained by winding a film sheet f around a roll axis, and opened upward,
A main body upper part 2 that covers the opening of the main body lower part 1 and that can be opened and closed between the opening front edge of the main body lower part 1 and draws out the film sheet f from the accommodated film roll F;
It can be moved between a housing position (S1) in which the blade is housed in the upper body 2 and a protruding position (S2) in which the blade is projected from the lower edge of the body upper 2 Cutting upper blade 20 supported by
And a bearing 8 that is inserted into both ends of the roll of the film sheet and accommodated in the accommodating portion of the lower body 1 together with the film sheet f.

本体上部２は本体下部１に対してロール軸と並行または同一軸をもって回転移動して、本体下部１の前曲板１４との間にフィルムシートｆの引き出し口７を有した開口状態（ｏ１、ｏ２）と、前曲板１４との間の引き出し口７が閉じられた閉口状態（ｓ１、ｓ２）とに状態変化する。   The main body upper part 2 rotates relative to the main body lower part 1 in parallel or with the same axis as the roll axis, and has an opening state (o1, The state changes to a closed state (s1, s2) in which the drawer port 7 between o2) and the front curved plate 14 is closed.

このうち開口状態は、本体上部２がロール軸よりも前方上部にある第一開口状態（ｏ１）と、ロール軸よりも後方上部第二開口状態（ｏ２）に分けられ、閉口状態は、本体上部２が本体下部１の下部前方に設けられた下刃収容部１３内に押し込まれずに口を閉じた第一閉口状態（ｓ１）と、下刃収容部１３内に押し込まれて第一閉口状態からさらにロール軸下方寄りに移動した第二閉口状態（ｓ２）に分けられる。   Of these, the open state is divided into a first open state (o1) in which the main body upper part 2 is located at the front upper part of the roll axis, and a rear upper second open state (o2) from the roll axis. From the first closed state (s1) in which the mouth 2 is closed without being pushed into the lower blade accommodating portion 13 provided in front of the lower portion of the main body lower portion 1, and from the first closed state by being pushed into the lower blade accommodating portion 13. Further, it is divided into a second closed state (s2) that has moved to the lower side of the roll axis.

そして本体上部２が回転移動して前記引き出し口７を閉じた閉口状態、さらにいえば前記第二閉口状態（ｓ２）において、切断上刃２０が前記収容位置（Ｓ１）から突出位置（Ｓ２）へ移動することで、収容部から引き出されたフィルムシートｆを切断する。以下、各構成につき詳述する。   Then, in the closed state in which the main body upper part 2 is rotated and the drawer port 7 is closed, more specifically, in the second closed state (s2), the cutting upper blade 20 moves from the accommodation position (S1) to the protruding position (S2). By moving, the film sheet f pulled out from the accommodating portion is cut. Hereinafter, each configuration will be described in detail.

（フィルムロールＦ）
フィルムロールＦは、長尺のフィルムシートｆが中空のロール軸回りに巻回されてなる。例えばＰＰ，ＰＥを主成分とする食品保存用の樹脂製ラップフィルムシートを使用することができるが、これに限定されず紙シート、アルミニウムシート、不織布シートを使用しても良い。実施例では幅３０ｃｍ、長さ１００ｍ、ロール外径５ｃｍ弱、ロール軸の内径２．７ｃｍのものを使用した。 (Film roll F)
The film roll F is formed by winding a long film sheet f around a hollow roll axis. For example, a resin wrap film sheet for preserving food containing PP and PE as main components can be used, but the present invention is not limited to this, and a paper sheet, an aluminum sheet, or a nonwoven fabric sheet may be used. In the examples, a material having a width of 30 cm, a length of 100 m, a roll outer diameter of less than 5 cm, and a roll shaft inner diameter of 2.7 cm was used.

（本体下部１）
本体下部１は、ロール状に巻回されたフィルムシートを収容しうる収容部を有する。 (Lower body 1)
The main body lower part 1 has an accommodating part which can accommodate the film sheet wound in roll shape.

本体下部１の開口からその下部は部分円柱板で構成されると共に、部分円柱板の先側から下方へ張り出した弾性材からなる張り出し片６を有する。   From the opening of the lower part 1 of the main body, the lower part is constituted by a partial cylindrical plate, and has a protruding piece 6 made of an elastic material protruding downward from the front side of the partial cylindrical plate.

本体下部１の前部には、部分円柱板面を有して引き出し口７の下縁を構成する前板１４が配される。前板１４は、本体下部１の両側板間であって本体下部１の前部に配置される。図１，２に示すように、フィルムロールＦのロール形状に沿う円柱側面を所定中心角で切断した部分円柱面を外面に有する。また本体下部の両側板の中央にはそれぞれ連結ピン５が外面から内面側へ貫通して取り付けられる。この連結ピン５は連結バネ４を連結しており、本体上部２の回転軸となる。   A front plate 14 having a partial cylindrical plate surface and constituting the lower edge of the drawer opening 7 is disposed in the front portion of the lower body portion 1. The front plate 14 is disposed between both side plates of the lower body portion 1 and at the front portion of the lower body portion 1. As shown in FIGS. 1 and 2, the outer surface has a partial cylindrical surface obtained by cutting a cylindrical side surface along the roll shape of the film roll F at a predetermined central angle. Further, connecting pins 5 are attached to the center of both side plates at the bottom of the main body so as to penetrate from the outer surface to the inner surface side. The connecting pin 5 connects the connecting spring 4 and serves as a rotation shaft of the upper part 2 of the main body.

前板１４の下方には前板１４よりも前方にせりあがって、それ自体の上面の前後方向略中央位置に切断下刃１０を収容した下刃収容部１３が設けられる。、切断下刃１０は、切断下口１００を上部に露出させて下刃収容部１３内に支持固定される。下刃収容部１３は、弾性体からなる上端面を有した受け座１１が上部に露出し、切断時に下降した本体上部２をこの受け座１１の上端面で受け止める。この受け座１１には、収容部から引き出したフィルムシートが一時的に張り付いて固定される。   Below the front plate 14, a lower blade accommodating portion 13 is provided that is positioned forward of the front plate 14 and accommodates the cutting lower blade 10 at a substantially central position in the front-rear direction of the upper surface of the front plate 14. The lower cutting blade 10 is supported and fixed in the lower blade accommodating portion 13 with the lower cutting opening 100 exposed at the top. In the lower blade accommodating portion 13, the receiving seat 11 having an upper end surface made of an elastic body is exposed at the upper portion, and the upper body 2 that is lowered during cutting is received by the upper end surface of the receiving seat 11. A film sheet pulled out from the accommodating portion is temporarily stuck to the receiving seat 11 and fixed.

前板１４の外面には、弾性材からなる張り出し片６が、前板１４の上部から下方へ張り出して設けられる。張り出し片６は片幅方向が上面湾曲した板ばね形状の弾性板からなり、上部が湾曲状の折り返し部で折り返され、当該折り返された一端の板面が前板１４の外面に貼り付け固定される。この貼り付け固定された一端から逆側の他端に向けて、前板１４から湾曲して浮き上がり、斜め下方に向かって前板１４から緩やかに離間するように張り出す。   A protruding piece 6 made of an elastic material is provided on the outer surface of the front plate 14 so as to protrude downward from the upper portion of the front plate 14. The overhanging piece 6 is made of a leaf spring-shaped elastic plate whose upper surface is curved in the width direction. The upper portion is folded back by a curved folded portion, and the folded plate surface of one end is attached and fixed to the outer surface of the front plate 14. The From the one end fixed and fixed to the other end on the opposite side, it curves and floats from the front plate 14 and projects obliquely downward so as to be gently separated from the front plate 14.

（本体上部２）
本体上部２は、収容ケース１の収容口を、前記フィルムロールのロール軸と並行軸回転することで開閉可能に覆う。本体上部２はまた、厚さ方向中央に切断上刃２０を収容する収容空間が形成され、その下縁は切断上刃２０の刃部が突出する突出口となっている。 (Upper part 2)
The main body upper portion 2 covers the accommodation port of the accommodation case 1 so as to be opened and closed by rotating in parallel with the roll axis of the film roll. The main body upper part 2 is also formed with an accommodation space for accommodating the upper cutting blade 20 at the center in the thickness direction, and its lower edge serves as a protruding opening from which the blade portion of the upper cutting blade 20 protrudes.

本体上部２の幅方向中央上部には切断刃２０のスイッチ部２３を露出させる上部窪み２Ｄが形成され、上部窪み２Ｄ内でスイッチ部２３が正面視斜め上下方向にストローク可能となっている。スイッチ部２３を本体上部２の下方へ押し下げることで、内部収容された切断上刃２０の刃部が支持軸を中心に正面視円弧状に斜め下方へ回動して突出口から突出する。   An upper dent 2D that exposes the switch portion 23 of the cutting blade 20 is formed in the upper central portion of the main body upper portion 2 in the width direction, and the switch portion 23 can be stroked in the up-down direction obliquely in front view in the upper dent 2D. By pushing down the switch portion 23 below the upper portion 2 of the main body, the blade portion of the cutting upper blade 20 housed therein rotates obliquely downward in a front view arc shape around the support shaft, and protrudes from the projection opening.

本体上部２の下縁は、断面両側が厚さ方向中央に向かう傾斜縁で先尖形状に形成された、表側及び裏側一対の押さえつけ部２９となっている。押さえつけ部２９の先部は切断上刃２０の突出口の断面両縁にて丸まって形成され、切断時に押さえつけ部２９先端が受け座１１の上面から内部方向へ突入し、中実弾性体の受け座１１を弾性圧縮することで、切断下口１００にあるフィルムシートｆを張り伸ばした状態とすることができる（図８ｅ）。   The lower edge of the upper part 2 of the main body 2 is a pair of front and back side pressing portions 29 that are formed in a pointed shape with inclined edges facing the center in the thickness direction on both sides of the cross section. The tip of the pressing portion 29 is formed rounded at both edges of the cross section of the protruding opening of the cutting upper blade 20, and the tip of the pressing portion 29 protrudes inward from the upper surface of the receiving seat 11 at the time of cutting. By elastically compressing the seat 11, the film sheet f in the cut lower opening 100 can be stretched (FIG. 8e).

また図２にて、切断上刃２０が突出した突出状態ｓ２で本体上部２を下ろして閉口状態としたときは、切断上刃２０の刃先は前方の受け座１１或いはガイド板１２に接触する状態となるように設定している。これにより、突出状態ｓ２にて本体上部２は上方へ持ち上がることがなく、第一開口状態Ｏ１とならないように構成されている。   In FIG. 2, when the upper body 2 is lowered to the closed state in the protruding state s <b> 2 in which the cutting upper blade 20 protrudes, the cutting edge of the cutting upper blade 20 is in contact with the front receiving seat 11 or the guide plate 12. It is set to become. Thereby, the main body upper part 2 is not lifted upward in the protruding state s2, and is configured not to be in the first opening state O1.

（切断上刃２０）
切断上刃２０は、本体上部内の上部近傍にて、上端支承された幅方向両側の２つの可動アーム２５によって、正面視側方から斜め下方まで円弧方向へ回転移動可能に連結支持される。またその中央上部には弾性支持アーム２６の下端が回動可能にピン支承され、このピン支承部を介して切断上刃２０自体が正面視一側方から弾性支持材２７によって側方支持される。 (Cutting upper blade 20)
The upper cutting blade 20 is connected and supported in the vicinity of the upper part in the upper part of the main body by two movable arms 25 on both sides in the width direction so as to be rotatable and movable in the arc direction from the front side to the obliquely lower side. Further, a lower end of the elastic support arm 26 is rotatably supported at the center upper portion thereof, and the upper cutting blade 20 itself is laterally supported by the elastic support member 27 from one side as viewed from the front via the pin support portion. .

弾性支持材２７は幅方向外側方の一端が本体上部２内に、他端が弾性支持アーム２６の上端に支持され、本体上部２の収容部内にて切断上刃２０を持ち上げた状態で弾性支持する。例えばゴム等の紐状弾性材のほか、図３のような引っ張りコイルばねを使用することができる。弾性支持アーム２６は、切断上刃２０の幅方向中央に設けた円弧孔２４内にて本体上部２に下端支承され、弾性支持アーム２６収容状態Ｓ１にて上端が弾性支持方向と逆方向側方へ僅かに傾斜した取り付け角度となっており、その傾斜角度が大きくなるように上端が回動可能となっている。   The elastic support member 27 has one end on the outer side in the width direction supported in the main body upper portion 2 and the other end supported on the upper end of the elastic support arm 26. The elastic support member 27 is elastically supported in a state where the cutting upper blade 20 is lifted in the housing portion of the main body upper portion 2. To do. For example, in addition to a string-like elastic material such as rubber, a tension coil spring as shown in FIG. 3 can be used. The elastic support arm 26 is supported by the upper end 2 of the main body 2 in an arc hole 24 provided at the center of the cutting upper blade 20 in the width direction, and the upper end of the elastic support arm 26 is in the opposite direction to the elastic support direction in the accommodation state S1. The mounting angle is slightly inclined to the top, and the upper end can be rotated so that the inclination angle increases.

切断上刃２０にはまた複数の円弧孔２４が正面視幅方向に等間隔に列設され、この中を誘導ピン２４Ｐで本体上部２内に支承することで、切断上刃２０の正面視円弧状の移動方向を誘導している。誘導ピン２４Ｐはこの円弧孔２４内を、前記可動アーム２５の可動軌跡とほぼ同軌跡（すなわち正面視側方から当該側方の斜め下方までの移動軌跡）となるように移動する。また誘導ピン２４Ｐは図２に示すように、外側及び内側の押さえつけ部２９同士の厚さ方向の間隔を保持し、切断上刃２０の突出口の大きさが容易に変わらないようにしている。   A plurality of arc holes 24 are also arranged in the cutting upper blade 20 at equal intervals in the front view width direction, and these are supported in the upper part 2 of the main body by the guide pins 24P. An arcuate direction of movement is guided. The guide pin 24P moves in the arc hole 24 so as to be substantially the same locus as the movable locus of the movable arm 25 (that is, the movement locus from the side in front view to the obliquely lower side of the side). Further, as shown in FIG. 2, the guide pin 24P maintains the distance in the thickness direction between the outer and inner pressing portions 29 so that the size of the protruding opening of the cutting upper blade 20 does not easily change.

切断上刃２０の幅方向中央上縁には、切断上刃２０の厚さ方向へ屈曲形成された指当てプレートからなるスイッチ部２３が突出形成される。スイッチ部２３の上縁は図７ｄに示す閉口状態ｓ１にて蓋部１６の上縁と同程度の高さに設定される。   A switch portion 23 made of a finger contact plate that is bent in the thickness direction of the upper cutting blade 20 is formed on the upper edge in the center in the width direction of the upper cutting blade 20. The upper edge of the switch part 23 is set to the same height as the upper edge of the lid part 16 in the closed state s1 shown in FIG. 7d.

スイッチ部２３を下方に押し下げると、図３破線に示すように、弾性支持材２７が弾性伸長し、可動アーム２５及び弾性支持アーム２６が斜め方向に回動することで、蓋部２の内部の収容位置から正面視円弧方向に沿って斜め下方へ弾性可動し、突出口から刃部が突出した突出状態となる。この上下方向のストローク距離は、円弧孔２４の上下端と誘導ピン２４Pの位置調整によって、７ｍｍ〜８ｍｍ以下、好ましくは６ｍｍ以下の短い距離に留めている。   When the switch portion 23 is pushed downward, the elastic support member 27 is elastically extended and the movable arm 25 and the elastic support arm 26 are rotated in an oblique direction, as shown by a broken line in FIG. It is elastically movable diagonally downward along the arc direction of the front view from the accommodation position, and the blade portion protrudes from the protrusion port. The vertical stroke distance is set to a short distance of 7 mm to 8 mm, preferably 6 mm or less, by adjusting the positions of the upper and lower ends of the arc hole 24 and the guide pin 24P.

（切断上刃２０の刃部）
切断上刃２０の刃部は、図４（ａ）に示すように切断上刃２０の下縁に、正面視上方への連続切り込み３０Ｄを形成し、各切り込み間の隣接境界に、鋭利な刃先を形成している。実施例１（図４ａ）では半円弧状の連続切り込み３０Ｄが幅方向に隣接形成され、連続切り込み３０Ｄの形成線が、刃部先端に向かって正面視傾きを二次曲線的に増加した湾曲線からなる。実施例２（図５）では側辺を傾斜直線とする倒立略コ字状の連続切り込み３０Ｄが幅方向に隣接形成され、連続窪み３０Ｄの形成線が、連続切り込み３０Ｄ間の刃先に向かって正面視傾きを鉛直方向に対して１５度以内の微傾斜のまま直線的に保持した湾曲線からなる。 (Blade part of cutting upper blade 20)
As shown in FIG. 4A, the cutting portion of the cutting upper blade 20 is formed with a continuous cutting 30D upward in the front view at the lower edge of the cutting upper blade 20, and a sharp cutting edge at an adjacent boundary between the cuttings. Is forming. In Example 1 (FIG. 4a), semicircular arc-shaped continuous cuts 30D are formed adjacent to each other in the width direction, and the formation line of the continuous cuts 30D is a curved line in which the inclination in front view increases in a quadratic curve toward the blade tip. Consists of. In Example 2 (FIG. 5), an inverted substantially U-shaped continuous cut 30D whose side is an inclined straight line is formed adjacently in the width direction, and the formation line of the continuous recess 30D faces the cutting edge between the continuous cuts 30D. It consists of a curved line in which the visual inclination is held linearly with a slight inclination within 15 degrees with respect to the vertical direction.

またこの連続切り込み３０Ｄの切り込み縁に沿って、下縁を刃先として傾斜する第一刃部３０が形成される。第一刃部３０はその上縁が連続切り込み３０Ｄの形状に添う形となっており、実施例１では倒立三日月状、実施例２では倒立コ字状の正面視形状からなる。第一刃部３０は連続切り込み３０Ｄの各切り込み幅の中央で最大高さ３０ＤＨとなる。フィルムシートｆとして柔軟性及び伸縮性を有する樹脂製のラップフィルムを使用する場合には、この最大高さ３０ＤＨは、切断上刃２０の上下移動距離の半分未満であることが好ましい。最大高さ３０ＤＨを最小限に抑えることで、切断時に必要とする切断上刃２０の上下移動量を少なくすることが可能となる。   Moreover, the 1st blade part 30 which inclines with a lower edge as a blade edge is formed along the cut edge of this continuous cut 30D. The upper edge of the first blade portion 30 has a shape that follows the shape of the continuous cut 30D. The first blade portion 30 has an inverted crescent shape in the first embodiment and an inverted U-shape in the second embodiment. The first blade portion 30 has a maximum height of 30DH at the center of each cut width of the continuous cut 30D. In the case where a plastic wrap film having flexibility and stretchability is used as the film sheet f, the maximum height 30DH is preferably less than half of the vertical movement distance of the cutting upper blade 20. By minimizing the maximum height 30DH, it is possible to reduce the amount of vertical movement of the cutting upper blade 20 required during cutting.

また連続切り込み３０Ｄの隣接境界の刃先には、第一刃部３０と同程度以上の傾斜角度で傾斜する第二刃部３１が形成される。なお、第二刃部３１は断面先端角度Ｑが第一刃部３０の断面先端角度Ｑとほぼ同一であり、第二刃部高さ３１Ｈは第一刃部高さ３０Ｈよりもわずかに小さい。   Moreover, the 2nd blade part 31 which inclines with the inclination angle more than the same as the 1st blade part 30 is formed in the blade edge of the adjacent boundary of continuous cut 30D. The second blade portion 31 has a cross-sectional tip angle Q that is substantially the same as the cross-sectional tip angle Q of the first blade portion 30, and the second blade portion height 31H is slightly smaller than the first blade portion height 30H.

例えば全幅３１２ｍｍ、上下方向移動量６ｍｍの切断上刃２０の場合、上下移動量の半分である深さ３ｍｍの半円形の切り込みを５０〜５５個連続形成し、鉛直方向に対して約１５〜３０度のいずれかの角度で両側傾斜した第二刃部３１の刃先を設け、第二刃部３１と同じ角度（約１５〜３０度のいずれかの角度）で両側傾斜した第一刃部３０を設けたものが好ましい。   For example, in the case of the cutting upper blade 20 having a total width of 312 mm and a vertical movement amount of 6 mm, 50 to 55 semicircular cuts having a depth of 3 mm, which is half of the vertical movement amount, are continuously formed, and about 15 to 30 in the vertical direction. The blade edge of the second blade part 31 inclined on both sides at any angle of degrees is provided, and the first blade part 30 inclined on both sides at the same angle as the second blade part 31 (any angle of about 15 to 30 degrees) is provided. Those provided are preferred.

さらに第一刃部３０の上部には正面視水平に延びる屈曲辺３４Ｌを境にして、その下方を下縁側の第一刃部３０方向に向かって傾斜させた第三刃部３４が形成される（図４ａ、図５）。   Further, a third blade portion 34 is formed on the upper portion of the first blade portion 30, with a bent side 34 </ b> L extending horizontally in front view as a boundary, and a lower portion thereof inclined toward the first blade portion 30 on the lower edge side. (FIGS. 4a and 5).

そして実施例１において、第三刃部３４は平面ではなく、正面視鉛直方向に伸びる断面先尖形状の大突条３２、小突条３３が幅方向に連続して形成される（図４ａ、図４ｄ）。特に図４ｄに示すように、断面先尖形状の大突条３２は複数の小突条３３の列毎に離間しながら配置される。実施例１（図４）では連続切り込み３０Ｄの各切り込み幅の中央位置と、各切り込み間の隣接境界にある刃先の位置とに離散して等間隔に配置される（図４ｄ）。大突条３２、小突条３３によってフィルムシートｆの刃部への不要な張り付きを防止することができる。また実施例２の第三刃部３４は、実施例１のような大突条３２、小突条３３の代わりに均等高さの突条が等間隔に列状形成される（図５）。   And in Example 1, the 3rd blade part 34 is not a plane, but the large ridge 32 and the small ridge 33 of the cross-section tip shape extended in a front view perpendicular direction are formed continuously in the width direction (FIG. 4a, FIG. 4d). In particular, as shown in FIG. 4 d, the large ridges 32 having a pointed cross section are arranged while being separated for each row of the plurality of small ridges 33. In Example 1 (FIG. 4), the center positions of the respective cut widths of the continuous cuts 30D and the positions of the cutting edges at the adjacent boundaries between the cuts are discretely arranged at equal intervals (FIG. 4d). The large protrusion 32 and the small protrusion 33 can prevent unnecessary sticking of the film sheet f to the blade portion. Further, in the third blade portion 34 of the second embodiment, instead of the large ridge 32 and the small ridge 33 as in the first embodiment, ridges of equal height are formed in rows at equal intervals (FIG. 5).

この第一刃部３０、第二刃部３１、第三刃部３３によって、少ない力、かつ少ないストローク量でフィルムシートｆを確実に切断することができる。特に実施例１の刃部は連続切り込み３０Ｄの形成線が刃部先端に向かって二次曲線状に可変したものからなり、形成線に沿ってフィルムシートｆの第一刃部３０による切り裂き縁の追従によって真っ直ぐに切断しやすい形状となっている。また実施例２の刃部は、連続切り込み３０Ｄの形成線が刃部先端に向かって傾きの小さい直線状のものからなり、フィルムシートｆの切断のきっかけとなる切断開始孔を作りやすい形状となっている。各刃部（３０〜３２）を構成する刃面は図４（ｂ）（ｃ）に示すように、厚さ方向に対称な両刃面となっているが、他の形態として上記刃面を厚さ方向片側のみに形成しても良い。   The first blade portion 30, the second blade portion 31, and the third blade portion 33 can reliably cut the film sheet f with a small force and a small stroke amount. In particular, the blade portion of Example 1 is formed by changing the formation line of the continuous cut 30D in a quadratic curve toward the tip of the blade portion, and the cutting edge of the first blade portion 30 of the film sheet f along the formation line. The shape is easy to cut straight by following. In addition, the blade portion of Example 2 is a linear shape in which the formation line of the continuous incision 30D is small in inclination toward the tip of the blade portion, and has a shape that makes it easy to create a cutting start hole that triggers the cutting of the film sheet f. ing. As shown in FIGS. 4B and 4C, the blade surfaces constituting the blade portions (30 to 32) are symmetric blade surfaces in the thickness direction. However, as another form, the blade surfaces are thick. It may be formed only on one side in the vertical direction.

（切断下刃１０、受け座１１）
切断下刃１０は外刃１０Ａと内刃１０Ｂとを両端に有して断面略コ字状に折り曲げ形成され、外刃１０Ａと内刃１０Ｂとの間に切断上刃２０が突出して入り込むための下切断口１００が形成される。切断下刃１０の外刃１０Ａと内刃１０Ｂは下方へ向かって下切断口１００の幅が広くなるように、断面ハの字状に形成され、各下縁同士が下面板で繋がれる。外刃１０Ａ、内刃１０Ｂそれぞれの外側面には、同一高さの上端面を有する中実体の弾性材からなる受け座１１を貼り付け固定してなる。 (Cutting lower blade 10, receiving seat 11)
The lower cutting blade 10 has an outer blade 10A and an inner blade 10B at both ends and is bent and formed into a substantially U-shaped cross section, and the upper cutting blade 20 protrudes and enters between the outer blade 10A and the inner blade 10B. A lower cut opening 100 is formed. The outer blade 10A and the inner blade 10B of the cutting lower blade 10 are formed in a cross-sectional C shape so that the width of the lower cutting port 100 becomes wider toward the lower side, and the lower edges are connected by a lower surface plate. A receiving seat 11 made of a solid elastic material having an upper end surface of the same height is attached and fixed to the outer surface of each of the outer blade 10A and the inner blade 10B.

下切断口１００は、切断上刃２０が僅かな隙間を有して入り込む距離で厚さ方向に離間し、上向きに対向配置された外刃１０Ａと内刃１０Ｂによって形成される。切断下刃１０の外刃１０Ａ、内刃１０Ｂの上端間距離である下切断口１００の入り口幅は、広すぎると切断上刃２０が突出したときに切れにくくなる一方、狭すぎて切断上刃２０と外刃１０Ａ、内刃１０Ｂのいずれかとが接触した場合にはさらに切れにくくなってしまう。また、切断下刃１０の変形によって入り口幅が狭まる動きをすれば切断上刃２０をつかむような形となり、連結ばねの弾性反力で切断上刃２０が持ち上がらなくなってしまう。このような状態を避けるため、切断下刃１０の上端に形成される下切断口１００の入り口幅は、受け座１１の弾性変形時にも変わることなく一定の幅を保ったまま、外刃１０Ａ、内刃１０Ｂがともに前後に可動し得るようになっている。   The lower cutting port 100 is formed by an outer blade 10A and an inner blade 10B that are spaced apart in the thickness direction by a distance that the upper cutting blade 20 enters with a slight gap and is opposed to face upward. If the entrance width of the lower cutting port 100 that is the distance between the upper ends of the outer blade 10A and the inner blade 10B of the cutting lower blade 10 is too wide, it becomes difficult to cut when the cutting upper blade 20 protrudes, while it is too narrow to cut the upper cutting blade. When 20 and any one of the outer blade 10A and the inner blade 10B come into contact with each other, it becomes more difficult to cut. Further, if the movement of the cutting lower blade 10 becomes narrower due to the deformation of the cutting lower blade 10, the cutting upper blade 20 is grasped, and the cutting upper blade 20 cannot be lifted by the elastic reaction force of the connecting spring. In order to avoid such a state, the entrance width of the lower cutting port 100 formed at the upper end of the lower cutting blade 10 is maintained at a constant width without changing even when the receiving seat 11 is elastically deformed. Both the inner blades 10B can move back and forth.

また受け座１１は押さえつけ部２９の沈み込みによって上面が断面円弧状に弾性変形する。これにより、受け座１１の上面に張り付いたフィルムシートｆを下切断口１００の内外両外方向に引っ張ると共に、内外両側面の押さえつけ部２９が互いに広がらずに下方移動するように導く。特にフィルムケースの長期使用によって切断下刃１０や切断上刃２０周りの形状のゆがみや可動軸５の遊びが生じた場合でも、受け座１１が歪みやズレを修正しての正しい方向へ誘導することができる。
また受け座１１は、切断下刃１０の刃先に指先等が接触してしまうのを防いで厚さ方向両側から切断下刃１０を支える役割を果たす。なお受け座１１の弾性変形によって、切断下刃１０の外刃１０Ａ、内刃１０Ｂの刃先間の距離（下切断口１００の幅）は変わらないが、外刃１０Ａ、内刃１０Ｂの刃先は共に前後に可動する。このとき本体上部２の押さえつけ部２９は切断上部１０と側面接触する。この側面接触によって、切断時の感触を使用者に返すことができる。 Further, the upper surface of the receiving seat 11 is elastically deformed into a circular arc shape by the depression of the pressing portion 29. As a result, the film sheet f attached to the upper surface of the receiving seat 11 is pulled in both the inside and outside directions of the lower cutting port 100, and the pressing portions 29 on both the inside and outside sides are guided so as to move downward without spreading. Even when the shape of the cutting lower blade 10 or the cutting upper blade 20 is distorted or the play of the movable shaft 5 occurs due to long-term use of the film case, the receiving seat 11 is guided in the correct direction after correcting the distortion and displacement. be able to.
Further, the receiving seat 11 plays a role of supporting the lower cutting blade 10 from both sides in the thickness direction by preventing a fingertip or the like from coming into contact with the cutting edge of the lower cutting blade 10. Although the distance between the cutting edges of the outer cutting edge 10A and the inner cutting edge 10B (the width of the lower cutting opening 100) of the lower cutting edge 10 does not change due to the elastic deformation of the receiving seat 11, the cutting edges of both the outer cutting edge 10A and the inner cutting edge 10B are the same. Move back and forth. At this time, the pressing portion 29 of the upper portion 2 of the main body comes into side contact with the cut upper portion 10. By this side contact, the feeling at the time of cutting can be returned to the user.

（軸受け８）
軸受け８は図６に示すように、フィルムロールＦの左右からロール軸内に挿入される一対の構成からなる。左右それぞれの軸受け８は具体的には、弾性体からなる棒状の挿入軸８３と、挿入軸８３の先側にて挿入軸８３よりも大径のものとして張出形成されたフランジ板８２と、挿入軸８３周囲の複数位置に貼り付け固定された固定板８１とから構成される。挿入軸８３は２〜５ｍｍ内径の異なるフィルムロールＦのロール軸内に挿入可能な円筒棒体であり、筒孔が中心軸棒８０に挿通して中心軸棒８０回りに所定の摩擦抵抗を持って摺動回転する。
フランジ板８２はこの中心軸棒８０の端部に垂直に固定されてフィルムロールＦよりも大径状に張り出す。固定板８１上部がフィルムロールＦのロール軸内面に摺動し、フランジ板８２が収容ケース１内で摺動する。このとき収容部内でのラップフィルムの回転に伴い、フランジ板８２と収容部、或いは固定板８１とフィルムシートｆの内筒面とが所定の摩擦抵抗をもって相対移動する。またフランジ板８２は、その周囲が収容ケース１の円柱状の収容部内に接しながら、所定の摩擦抵抗を持って本体下部１内で軸回転しうる。また軸受け８は、ロール内に挿入可能な軸本体の周囲の複数位置において、軸本体周面から上方に固定板８１が並行して張設される。軸受け８は、固定板８１とフィルムロールＦのロール軸内部との回転抵抗で回る状態が好ましいが、内径の小さいフィルムロールＦを使用する場合には、フランジ板８２と収容ケース１との回転抵抗を利用するようにしたものである。 (Bearing 8)
As shown in FIG. 6, the bearing 8 has a pair of structures inserted into the roll shaft from the left and right sides of the film roll F. Specifically, each of the left and right bearings 8 includes a rod-shaped insertion shaft 83 made of an elastic body, and a flange plate 82 that is formed on the front side of the insertion shaft 83 so as to have a larger diameter than the insertion shaft 83. The fixing plate 81 is fixed to a plurality of positions around the insertion shaft 83. The insertion shaft 83 is a cylindrical rod body that can be inserted into the roll shaft of a film roll F having a different inner diameter of 2 to 5 mm. The cylindrical hole is inserted through the central shaft rod 80 and has a predetermined friction resistance around the central shaft rod 80. To slide and rotate.
The flange plate 82 is fixed perpendicularly to the end of the central shaft rod 80 and protrudes in a larger diameter than the film roll F. The upper part of the fixed plate 81 slides on the inner surface of the roll shaft of the film roll F, and the flange plate 82 slides in the housing case 1. At this time, along with the rotation of the wrap film in the accommodating portion, the flange plate 82 and the accommodating portion, or the fixed plate 81 and the inner cylindrical surface of the film sheet f are relatively moved with a predetermined frictional resistance. Further, the flange plate 82 can rotate around the lower portion 1 of the main body 1 with a predetermined frictional resistance while the periphery thereof is in contact with the cylindrical storage portion of the storage case 1. The bearing 8 has a fixed plate 81 extending in parallel upward from the peripheral surface of the shaft body at a plurality of positions around the shaft body that can be inserted into the roll. The bearing 8 is preferably rotated by the rotational resistance between the fixed plate 81 and the inside of the roll shaft of the film roll F. However, when the film roll F having a small inner diameter is used, the rotational resistance between the flange plate 82 and the housing case 1 is used. Is to use.

（作動状態）
作動状態においては、支持軸から上方のスイッチ部側方へ弾性支持された切断上刃が支持軸を中心に円弧状に斜め下方へ回動することで突出状態となる。切断下刃２０の対向する下刃１０Ａ，１０Ｂの間に切断上刃２０が入ることで切断を行う。 (Operating state)
In the operating state, the cutting upper blade elastically supported from the support shaft to the side of the upper switch part turns into a projecting state by rotating obliquely downward in an arc shape around the support shaft. Cutting is performed by the cutting upper blade 20 entering between the lower blades 10 </ b> A and 10 </ b> B facing the cutting lower blade 20.

フィルムシートｆを引き出し口７から引き出したとき、本体下部１の引き出し口７下部の部分円柱板面を有する引き出し前板１４に沿って斜め下方へ張り出した弾性材からなる張り出し片６によって持ち上げられ、前曲板１４へのフィルムシートｆの貼りつきが防止される（図７ｂ、ｃ）。この引き出した状態から各作動状態によってフィルムシートｆを切断する。   When the film sheet f is pulled out from the drawer port 7, it is lifted by the projecting piece 6 made of an elastic material that projects obliquely downward along the front drawer plate 14 having a partial cylindrical plate surface at the lower part of the drawer port 7 of the lower body 1. The film sheet f is prevented from sticking to the front curved plate 14 (FIGS. 7b and 7c). The film sheet f is cut from the pulled-out state according to each operation state.

スイッチ部２３を押し下げることで、本体上部２が押し下げられ、図７ｄ、図８ｄに示す第一閉口状態（ｓ１）となる。この第一閉口状態（ｓ１）では、押さえつけ部２９の先端が受け座１１の表面に当接して、引き出したフィルムシートｆは押さえつけ部２９と受け座１１にはさまれて、受け座１１の上面に一時的に張り付いて固定される。またフィルムシートｆの一時的に固定された部分の前後は、受け座１１の厚さ方向前後にせり上がったガイド板１２の側面にも部分的に張り付いて係止される（図７ｄ、図８ｄ）。   By pushing down the switch part 23, the main body upper part 2 is pushed down, and it will be in the 1st closed state (s1) shown to FIG. 7d and FIG. 8d. In the first closed state (s 1), the tip of the pressing portion 29 comes into contact with the surface of the receiving seat 11, and the drawn film sheet f is sandwiched between the pressing portion 29 and the receiving seat 11 and the upper surface of the receiving seat 11. Affixed temporarily to. In addition, the front and rear of the temporarily fixed portion of the film sheet f are partially stuck to the side surface of the guide plate 12 raised in the thickness direction of the receiving seat 11 (FIG. 7d, FIG. 7). 8d).

この第一閉口状態（ｓ１）から更にスイッチ部２３を押し下げることで、押さえつけ部２９の先端が受け座１１内へ沈み込んだ第二閉口状態（ｓ２）となる（図７ｅ、図８ｅ）。第二閉口状態（ｓ２）では、切断下刃２０の両外側に貼り付けられた受け座１１の上面が押さえつけ部２９の先端形状に沿って湾曲状に弾性変形し、受け座１１の上面に貼り付けられたフィルムシートｆを、下切断口１００を境として厚さ方向両外方向へ引っ張った状態となる。また受け座１１の弾性変形によって切断下刃１０の外刃１０Ａと内刃１０Ｂとの距離は略一定のまま前後方向へ僅かに動く。これにより切断上刃２０は下切断口１００内の厚さ方向中央位置へ導かれる。   By further depressing the switch portion 23 from the first closed state (s1), the second closed state (s2) in which the tip of the pressing portion 29 sinks into the receiving seat 11 is obtained (FIGS. 7e and 8e). In the second closed state (s2), the upper surface of the receiving seat 11 attached to both outer sides of the cutting lower blade 20 is elastically deformed in a curved shape along the tip shape of the pressing portion 29, and is attached to the upper surface of the receiving seat 11. The attached film sheet f is pulled in the thickness direction both outwards from the lower cutting opening 100 as a boundary. The distance between the outer blade 10A and the inner blade 10B of the cutting lower blade 10 is slightly moved in the front-rear direction while being substantially constant due to the elastic deformation of the receiving seat 11. Thereby, the cutting upper blade 20 is guided to the center position in the thickness direction in the lower cutting port 100.

第二閉口状態（ｓ２）においてスイッチ部２３を更に押し下げることで、第二開口状態（ｓ２）のまま、切断上刃２０が下方へ弾性移動し、刃部が突出口から突出した突出状態（Ｓ２）となる（図７ｆ、図８ｆ）。押し下げた下端では、スイッチ部２３の下面が本体上部２の上部窪み２Ｄと接し、切断上刃２０に設けられた円弧孔２４内の誘導ピン２４Ｐが、円弧孔２４の上端に位置することで、使用者に手ごたえを感じさせる。   By further pressing down the switch portion 23 in the second closed state (s2), the cutting upper blade 20 is elastically moved downward in the second open state (s2), and the protruding state in which the blade portion protrudes from the protruding port (S2). (FIGS. 7f and 8f). At the lower end pushed down, the lower surface of the switch portion 23 is in contact with the upper recess 2D of the upper body 2 and the guide pin 24P in the arc hole 24 provided in the cutting upper blade 20 is positioned at the upper end of the arc hole 24. Make the user feel the response.
