Description

本発明は、テーブルや机などの上に置いて薬、栄養剤、栄養補助剤、菓子などの中身が入った小袋を素早く安全に切断する安全カッター及び、冷蔵庫などに取り付けて食品が入ったビニール袋、カウチパックや牛乳などが入っていた紙パックを素早く安全に切断する安全カッターに関するものである。 The present invention is a safety cutter that can be placed on a table or desk to quickly and safely cut a pouch containing medicines, nutritional supplements, dietary supplements, confectionery, etc., and a vinyl that can be attached to a refrigerator or the like to contain food. It is related to a safety cutter that quickly and safely cuts paper packs containing bags, couch packs, milk, etc.

近年、健康に対する関心が高まっており、薬や栄養剤、栄養補助剤を毎日摂取する人が増えている中で、これらの袋は細長くギザギザがある縦方向には手でカット出来るが、中身がこぼれるので横方向にカットするためハサミを使ったり、横方向にスリットが入っていても、指の力が弱かったり、目が悪くスリットが見えなかったり、暗くてスリットが見えなかったりした時なども、ハサミを使っていた。又近年、野菜や調理済み品をビニール袋やカウチパックに入れた食品が、調理技術や冷凍技術の向上で温めるだけでおいしく食べられるし素早く調理できるので、家庭だけでなく飲食店、介護施設、病院などでも多く利用されており、これらビニール袋やカウチパックの中にはスリットが入っていて手で破れるようになっているが、スリットがないビニール袋や手が濡れて滑って破れない場合は、はさみでカットすることがしばしばであった。 In recent years, there has been increasing interest in health, and as more and more people take medicines, nutritional supplements, and nutritional supplements every day, these bags can be cut by hand in the elongated, jagged vertical direction, but the contents are You can use scissors to cut laterally because it spills, or even if there are slits in the lateral direction, your fingers may be weak, you may not be able to see the slits due to poor eyesight, or you may not be able to see the slits because it is dark. , I was using scissors. Also, in recent years, foods in which vegetables and cooked foods are put in plastic bags or couch packs can be eaten deliciously just by warming them with improvements in cooking technology and freezing technology, and can be cooked quickly. It is often used in hospitals, etc., and these plastic bags and couch packs have slits that can be torn by hand, but if the plastic bag without slits or your hands get wet and cannot be torn, , Often cut with scissors.

しかしながら、このところ 病院、介護施設、事務所などでは新型コロナウイルスの感染の影響で、ハサミなどの道具の使いまわしも感染の可能性があり、いちいちアルコール除菌することも求められている。この対策として、切断のための道具を持たず、テーブルや机などの上に置いて、又は冷蔵庫などに取り付けて、ベース部と立設部の間にローラーとサポートフレームと切断刃を取り付け、ローラーとカッター刃の間で袋をカットする安全カッターが提案されている。これにより直接袋を持ってカット出来、ハサミなどの道具の使い回しがないので、コロナウイルス感染のリスクも減り、手やビニール袋が濡れていたり、室内が薄暗くスリットが見えにくかったりした時でも、色々な物が入った袋を素早く容易にカットでき、カッター刃さえ交換すれば半永久的に使用でき便利ではあるが、刃の交換にペンチなどの工具が必要で、切断刃の刃先のカバーもその都度、外したりつけたりする必要あり手間がかかり、又大きくて使用しない時は邪魔で、構成部品も多く構造も複雑でコスト高になり、販売を拡大するまでには至らなかった。 However, recently, due to the influence of the new coronavirus infection in hospitals, long-term care facilities, offices, etc., there is a possibility that reusing tools such as scissors may cause infection, and alcohol sterilization is also required one by one. As a countermeasure, do not have a tool for cutting, place it on a table or desk, or attach it to a refrigerator etc., attach a roller, support frame and cutting blade between the base part and the standing part, and roll A safety cutter that cuts the bag between the cutter blade and the cutter blade has been proposed. This allows you to hold the bag directly and cut it without reusing tools such as scissors, reducing the risk of coronavirus infection, even when your hands or plastic bag are wet or the room is dim and the slits are difficult to see. It is convenient to cut a bag containing various things quickly and easily, and it can be used semi-permanently if only the cutter blade is replaced. It takes time and effort to remove and attach it, and it is a hindrance when it is not used because it is large, and the structure is complicated with many components and the cost is high, so it was not possible to expand sales.

この改良品として切断刃だけを取り付けた、最もシンプルで小型の安全カッターも提案されているが、切断刃などの交換ができない使いきりの物だったので、商品としては物足りない物であった。 As this improved product, the simplest and smallest safety cutter with only a cutting blade attached has been proposed, but it was a single-use product with a non-replaceable cutting blade, so it was unsatisfactory as a product.

解決しようとする課題は、テーブルや机などの上に置いて、薬や栄養剤や栄養補助剤が入った袋を素早くカット出来る又は、冷蔵庫などに取り付けて食品が入ったビニール袋やカウチパックなどを素早くカット出来るだけでなく、切れなくなった刃をペンチなどの工具を使わず、折って又は、取り外して交換できるようにした安全カッターを、いかにしてコンパクトでシンプル且つ扱い易いものにするかである。 The problem to be solved is that you can quickly cut the bag containing medicines, nutritional supplements and nutritional supplements by placing it on a table or desk, or attach it to a refrigerator etc. and attach it to a plastic bag or pliers pack containing food. How to make a safety cutter that not only can cut quickly, but also allows the blade that cannot be cut to be folded or removed and replaced without using tools such as pliers, to be compact, simple and easy to handle. be.

本発明は、テーブルや机などの上に置ける平面又は、冷蔵庫の側面などに取り付ける平面のベース部に、この平面に対して垂直で重なった面を持つ立設部の内側に、切断刃を長手方向にスムーズにスライドさせベースから取り出せるようにした筒状で上下方向からやや傾斜したガイド部を設け、このガイド部の片方の面に、切断刃の折れ溝のピッチに合わせた複数の取り付け穴を設け、もう一方の面にガイド孔を設け、刃先を上向きにした切断刃をねじと破断溝を持ったナットで取り付けている。立設部には、ガイド部を上から下に横断し指が入らない程の隙間のスリット部を設け、このスリット部に薬や栄養剤などが入った袋や食品が入ったビニール袋やカウチパックなどを通し切断するようにしている。又、ガイド部の先端には、根本が切断刃の板がぎりぎり通る程の幅と、先端に指が切断刃に触れない程の出代を持った末広がり状のテーパー部を設け、切断刃を1ピッチ進めれば、テーパー部の根本に切断刃折れ溝が来て、切断刃が簡単に折れるようにし、テーパー部の先で、指が切断刃に触れないようにしてそのままでも安全に使用できるようにしており、これらが最も主要な特徴となる。 In the present invention, the cutting blade is elongated inside a vertical portion having a plane that can be placed on a table, a desk, or the like, or a flat base that is attached to the side surface of a refrigerator, and has a surface that overlaps the plane perpendicularly. A cylindrical guide part that slides smoothly in the direction and can be taken out from the base is provided, and on one side of this guide part, multiple mounting holes that match the pitch of the bending groove of the cutting blade are provided. A guide hole is provided on the other surface, and a cutting blade with the cutting edge facing upward is attached with a screw and a nut having a breaking groove. The upright part is provided with a slit part that crosses the guide part from top to bottom and has a gap that does not allow fingers to enter, and this slit part is a bag containing medicine or nutritional supplements, a plastic bag containing food, or a couch. I try to cut it through a pack. Further, the tip of the guide portion is provided with a divergent tapered portion having a width at which the base of the cutting blade barely passes through and a margin at the tip so that the finger does not touch the cutting blade. If you advance one pitch, the cutting blade break groove will come to the root of the tapered part so that the cutting blade can be easily broken, and you can use it safely as it is without touching the cutting blade with your finger at the tip of the tapered part. These are the most important features.

テーブルや机の上に置いて薬や栄養剤の袋を素早く安全にカットする、及び冷蔵庫などに取り付けてビニール袋やカウチパックなどを素早く安全にカットし、切れなくなった切断刃は、ねじを緩め、ナットを外し、1ピッチ進めれば、テーパー部の根本から切断刃が1ピッチ分だけ出て、外したナットの破断溝で容易に折ることが出来、テーパーの先で指が触れないので、そのままの位置で安全に使用でき、破断溝を持つナットも切断刃と共に立設部のガイド部にねじで固定されるし、ねじの先もナットで隠れるので安全で、コンパクトでシンプル且つ扱いやすい安全カッターをわずかな部品点数にすることが出来た。 Place it on a table or desk to quickly and safely cut medicine and nutritional supplement bags, and attach it to a refrigerator to quickly and safely cut plastic bags and couch packs. If you remove the nut and advance by 1 pitch, the cutting blade will come out by 1 pitch from the root of the taper part, you can easily break it at the breaking groove of the removed nut, and your finger will not touch it at the tip of the taper. It can be used safely in the same position, the nut with a breaking groove is fixed to the guide part of the standing part with a screw together with the cutting blade, and the tip of the screw is also hidden by the nut, so it is safe, compact, simple and easy to handle. We were able to reduce the number of parts to the cutter.

テーブルや机などの上に置いて、薬や栄養剤、栄養補助剤などが入った袋を素早く安全にカットし、又は冷蔵庫などに取り付けて中身が入ったビニール袋やカウチパック、牛乳などが入っていた紙パックなど素早く安全にカットし、切れなくなった切断刃を折って又は外して交換できるようになり、安全でコンパクトで扱いやすい安全カッターを最小の部品点数にすることが出来たので、いろいろな分野の多くの人が使用しやすくなった。 Place it on a table or desk to quickly and safely cut a bag containing medicines, nutritional supplements, nutritional supplements, etc., or attach it to a refrigerator to hold a plastic bag, couch pack, milk, etc. It is now possible to quickly and safely cut paper packs, etc., and to fold or remove the cutting blades that cannot be cut and replace them. It has become easier to use for many people in various fields.

ベース部と立設部にローラーとサポートフレームと切断刃を取り付け、ローラーと切断刃の間でビニール袋をカットする従来の安全カッターに対し、本発明は図1、図2、図7に示すよう、テーブルや机など上に置けるような平面を持つベース部1と、この面に垂直で重なった立設部2の二重の面の間に、切断刃10を長手方向にスライドさせ、立設部2から取り出せるようにした筒状で上下方向から片側にやや傾斜したガイド部5を設けている。立設部2には、上下方向でガイド部5を横断し、指が入らない程度の隙間のスリット部7を設けており、このスリット部7に色々なビニール袋などを通して切断するようにしている。 As shown in FIGS. 1, 2, and 7, the present invention is different from the conventional safety cutter in which a roller, a support frame, and a cutting blade are attached to a base portion and an upright portion to cut a plastic bag between the roller and the cutting blade. , The cutting blade 10 is slid in the longitudinal direction between the base portion 1 having a flat surface that can be placed on a table or a desk and the double surface of the standing portion 2 that is perpendicular to this surface and stands upright. A tubular guide portion 5 that can be taken out from the portion 2 and slightly inclined from the vertical direction to one side is provided. The upright portion 2 is provided with a slit portion 7 having a gap that does not allow a finger to enter across the guide portion 5 in the vertical direction, and various plastic bags or the like are passed through the slit portion 7 for cutting. ..

ガイド部5の片方の面には図8に示すように、切断刃10の切断刃折れ溝12のピッチに合わせ、図5に示すように複数の取り付け穴3を設け、反対側の面にはガイド孔4を設けており、刃先を上向きにした切断刃10の保持穴11をガイド部5の取り付け穴3に、破断溝14を持つナット13と共にねじ15で取り付けている。 As shown in FIG. 8, a plurality of mounting holes 3 are provided on one surface of the guide portion 5 in accordance with the pitch of the cutting blade bending groove 12 of the cutting blade 10 as shown in FIG. 5, and a plurality of mounting holes 3 are provided on the opposite surface. A guide hole 4 is provided, and a holding hole 11 of the cutting blade 10 with the cutting edge facing upward is attached to the mounting hole 3 of the guide portion 5 with a screw 15 together with a nut 13 having a breaking groove 14.

立設部2のガイド部5の先端には、図6のように根本に切断刃10がぎりぎり通る程度の隙間で、先に指が切断刃10に触れない程度の出代で末広がり状のテーパー部6を設け、切断刃10の破断時に、この根本に切断刃折れ溝12が来るようにし、切断刃10が折れやすくなるようにしている。 As shown in FIG. 6, there is a gap at the tip of the guide portion 5 of the upright portion 2 so that the cutting blade 10 can barely pass through the root, and the taper is widened to the extent that the finger does not touch the cutting blade 10 first. A portion 6 is provided so that when the cutting blade 10 is broken, the cutting blade bending groove 12 comes to the root thereof so that the cutting blade 10 can be easily broken.

ナット13は、図3のような略字状の断面の鋼板からなり、図5に示すような切断刃が入る程の隙の破断溝14が設けられている。 The nut 13 is made of a steel plate having a substantially C -shaped cross section as shown in FIG. 3, and is provided with a breaking groove 14 having a gap enough to accommodate a cutting blade as shown in FIG.

又ベース部1の底の面側には、本体をテーブルや机に置いたときの衝撃や衝撃音を防ぐためクッション用として滑り止めマット17を設けている。 A non-slip mat 17 is provided on the bottom surface side of the base portion 1 as a cushion to prevent impact and impact noise when the main body is placed on a table or desk.

図1に示すように、薬や栄養剤が入った袋21をカットする場合は、立設部2のスリット部7に、栄養剤が入った袋21の端と少し内側を両手の指で摘まんで通せば、容易にカットでき、切断刃10が切れなくなった時は、ねじ15を外し、ガイド孔4から切断刃10の保持穴11をねじ15の先端で誘導させて取り付け穴3を1ピッチずらしてねじ15を差し込めば、テーパー部6から切断刃10が1ピッチ分出てきて、切断刃10の刃先を図9のようにナット13の破断溝14に差し込み破断することが出来る。又その状態のままでナット13を取り付け穴3にセットすれば、ねじ15でガイド部5に取り付けることが出来、切断刃10を破断した後そのまま使用しても、テーパー部6の先端で指がカバーされ切断刃10に指が触れないので安全に使用できる。又、ねじ15の先端はナット13で覆われているので安全に使用できる。 As shown in FIG. 1, when cutting a bag 21 containing a medicine or a nutritional supplement, the end and a little inside of the bag 21 containing the nutritional supplement are pinched by the fingers of both hands in the slit portion 7 of the upright portion 2. If the cutting blade 10 cannot be cut, remove the screw 15 and guide the holding hole 11 of the cutting blade 10 from the guide hole 4 with the tip of the screw 15 to guide the mounting hole 3 by 1 pitch. If the screw 15 is inserted with a shift, the cutting blade 10 comes out from the tapered portion 6 by one pitch, and the cutting edge of the cutting blade 10 can be inserted into the breaking groove 14 of the nut 13 to break as shown in FIG. If the nut 13 is set in the mounting hole 3 in that state, it can be mounted on the guide portion 5 with the screw 15, and even if the cutting blade 10 is broken and then used as it is, the finger will be at the tip of the tapered portion 6. Since it is covered and the cutting blade 10 is not touched by a finger, it can be used safely. Further, since the tip of the screw 15 is covered with the nut 13, it can be used safely.

この安全カッターのベース部1と立設部2を一体にし、薄鋼板で図10のようなベースの展開形状にし、連結部8を中心にして図2,3のように折り曲げ、スポット溶接9等で補強するようにすれば1部品に出来、更に部品点数も少なくなる。 The base portion 1 and the erecting portion 2 of this safety cutter are integrated, a thin steel plate is used to form a developed shape of the base as shown in FIG. 10, and the connecting portion 8 is bent as shown in FIGS. If it is reinforced with, it can be made into one part, and the number of parts is also reduced.

本発明は図11、図12,図13に示すように、ベース部1から立設部2に含む構造は実施例1と全く同じであるが、図15の断面に示すように、立設部2を持つこのベース部1の裏面側に、固定材としての磁石16を圧入、接着等で取り付け、これらに滑り止めマット17を取り付けている。 The present invention 11, 12, as shown in FIG. 13, but the structure including the base unit 1 to the standing portion 2 is exactly the same as in Example 1, C in FIG. 15 - as shown in C cross section, A magnet 16 as a fixing material is attached to the back surface side of the base portion 1 having the upright portion 2 by press fitting, adhesion, or the like, and a non-slip mat 17 is attached to these.

これにより磁力でこの安全カッターを冷蔵庫などに取り付けることが出来、又滑り止めマット17で容易にずれないので、縦にして冷蔵庫などに取り付け、牛乳が入っていた紙パックやキッチンペーパーの芯などをカットすることが出来、図16で示すように横にして冷蔵庫などに取り付け、食品が入った幅の広いビニール袋19やカウチパック、だし汁が入ったビニール袋などを、中身がこぼれないようスムーズにカットすることができる。又切れなくなった切断刃10は実施例1と同様スムーズに交換でき、ベース部1と立設部2を一体にして薄鋼板で図17のような展開図にすれば、実施例1と同様、最小の部品点数の安全カッターとなる。又ベース部1に磁石16と滑り止めマット17の代わりに、粘着マット、吸盤、ねじ、カシメ、接着剤などを取り付けて、冷蔵庫などに取り付け使用することも可能である。 As a result, this safety cutter can be attached to a refrigerator or the like by magnetic force, and since it does not easily shift with the non-slip mat 17, it can be attached vertically to a refrigerator or the like, and a paper pack containing milk or a core of kitchen paper can be attached. It can be cut, and as shown in Fig. 16, it can be laid down and attached to a refrigerator, etc., and a wide plastic bag 19 containing food, a couch pack, a plastic bag containing soup stock, etc. can be smoothly placed so that the contents do not spill. Can be cut. Further, the cutting blade 10 that cannot be cut can be replaced smoothly as in the first embodiment, and if the base portion 1 and the standing portion 2 are integrated into a thin steel plate to form a developed view as shown in FIG. 17, the same as in the first embodiment. It is a safety cutter with the minimum number of parts. Further, instead of the magnet 16 and the non-slip mat 17, the adhesive mat, suction cup, screw, caulking, adhesive or the like can be attached to the base portion 1 and attached to a refrigerator or the like for use.

小さくて、極めてシンプルで扱いやすい安全カッターなので、テーブルや机や色々な物の上に置く実施例1のタイプで、薬や栄養剤などが入った袋、ビニール紐、釣り糸、などを素早くカット出来、冷蔵庫などに取り付ける実施例2のタイプでは、中身が入った食品のビニール袋やカウチパック以外、色々な液体が入った袋などもこぼさずにカット出来、はさみやカッターなど道具の使い回しがないので、新型コロナウイルスの感染予防にもなり、家庭以外、病院、介護施設、飲食店、移動店舗などで様々な使い道が考えられる。 Since it is a small, extremely simple and easy-to-use safety cutter, it can quickly cut bags containing medicines and nutrients, vinyl strings, fishing threads, etc. with the type of Example 1 placed on a table, desk or various objects. In the type of Example 2 to be attached to a refrigerator, etc., it is possible to cut without spilling bags containing various liquids other than plastic bags and couch packs of food containing the contents, and there is no need to reuse tools such as scissors and cutters. , It also prevents the infection of the new coronavirus, and can be used in various ways other than at home, in hospitals, nursing homes, restaurants, mobile stores, etc.
