Description
この考案は、従来広く使用されている木製割箸の代りに開発したプラスチック製割箸に関する。 This invention relates to a plastic disposable chopstick developed in place of a widely used wooden disposable chopstick.
従来割箸は総て木製であって、我が国では年間300億膳〜350億膳使用するといわれ、前記の85%は外国からの輸入に依存している。 Conventional chopsticks are all made of wood and are said to be used between 30 billion to 35 billion liters per year in Japan, and 85% of the above depend on imports from abroad.
一方我が国の食文化として、一度使用した箸を二度使用しない習慣となっており、いわゆる使用時に割ることにより、一度だけ使用する点を担保するものである。 On the other hand, it is customary not to use chopsticks once used as a food culture in Japan, and it is guaranteed that the chopsticks are used only once by dividing them when used.
前記のように割箸は一度使用すると、二度と使用しないこと、再生利用の道がないので、年間300億膳以上廃棄され、資源の無駄使いになっていた。
現在使用されている割箸は総て木製であり、かつ85%は輸入である。従って木材資源の枯渇による輸出制限があれば、忽ち価格が高騰し、経営難を生じるおそれがあり、再使用については、衛生上の問題があって、未だ確実な解決策はない。 All chopsticks currently in use are wooden, and 85% are imported. Therefore, if there are export restrictions due to depletion of timber resources, there is a risk that the price will rise and management will be difficult. Reuse is a sanitary problem and there is still no reliable solution.
前記のように、割箸を合成樹脂製にしようとする提案もあるが、未だ普及するに到っていない。前記提案が普及するに到らない理由としては、低価格の木製割箸に対抗できないか、使用済箸の処理か、又は割難い形状から来ることも考えられる。 As described above, there is a proposal to make the disposable chopsticks made of a synthetic resin, but it has not yet spread. The reason why the proposal does not become widespread may be that it cannot compete with low-priced wooden disposable chopsticks, or is due to processing of used chopsticks, or a difficult shape.
前記価格については、輸入割箸の価格上昇と、合成樹脂成形技術上の工夫により多数高速成形することで解決できる。また使用済箸の処理については、再生できる樹脂又は生分解性樹脂を用いることにより、再生又は微生物処理などにより廃棄物を少なくすることにより解決できる。更に割り易くする為の工夫を加えることにより、前記従来の問題点を解決したのである。 The above-mentioned price can be solved by increasing the number of imported disposable chopsticks and by molding a large number of high-speed moldings based on synthetic resin molding technology. In addition, the treatment of used chopsticks can be solved by using a recyclable resin or a biodegradable resin to reduce waste by regeneration or microbial treatment. Furthermore, the conventional problems have been solved by adding a device for making it easier to split.
この考案は、多量生産方式を採用すると共に、引裂容易に合成樹脂を用い、かつ引裂容易な形状にすることにより、前記従来の問題点を解決したのである。 This device solves the above-mentioned conventional problems by adopting a mass production system, using a synthetic resin for easy tearing, and making it easy to tear.
即ちこの考案は、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記角形の隅部を薄皮で連結すると共に、中間部の四面には断面凹状の溝を設け、前記先端側の物品挟着域に、複数段の環状溝を設けたことを特徴とするプラスチック製割箸であり、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記角形の隅部を薄皮で連結すると共に、中間部の四面には断面凹状の溝を設け、前記先端側の物品挟着域は先端側を細くし、基端側を太くして、該部に、複数段の環状溝を設けたことを特徴とするプラスチック製割箸である。 That is, in this device, two plastic rivets with a distal end side having a circular shape and a base end side having a square shape are arranged in parallel, and the corner portions of the square shape are connected with a thin skin, and the four sides of the intermediate portion are connected to each other. A plastic disposable chopstick provided with a groove having a concave cross section, and provided with a plurality of annular grooves in the article sandwiching area on the distal end side. Two plastic cages thickened as a square cross section are juxtaposed, and the corners of the square are connected by a thin skin, and grooves having a concave cross section are provided on the four sides of the intermediate part, and the article sandwiching area on the tip side is on the tip side. A plastic disposable chopstick characterized in that it is thinned, the base end side is thickened, and a plurality of annular grooves are provided in the portion.
また他の考案は、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記角形の隅部を薄皮で連結すると共に、前記薄皮の下縁に切込みを入れ、前記プラスチック杆の中間部の四面には断面凹状の溝を設け、前記先端側の物品挟着域は先端側を細くし、基端側を太くして、該部に、複数段の環状溝を設けたことを特徴とするプラスチック製割箸であり、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記角形の隅部を薄皮で連結すると共に、中間部の四面には断面凹状の溝を設け、前記先端側の物品挟着域に、複数段の環状溝を設け、前記基端側の角形部と、先端側の円形部との間は、ほぼ同一断面の隅部円弧の方形であり、全長に亘り凹孤溝が設けられたことを特徴とするプラスチック製割箸であり、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記角形の隅部を薄皮で連結すると共に、前記薄皮の下縁に三角状切込みを入れ、前記プラスチック杆の中間部の四面には断面凹状の溝を設け、前記先端側の物品挟着域は先端側を細くし、基端側を太くして、該部に、複数段の環状溝を設け、前記基端側の角形部と、先端側の円形部との間は、ほぼ同一断面の隅部円弧の方形であり、全長に亘り凹孤溝が設けられたことを特徴とするプラスチック製割箸である。 In another aspect, the plastic side is thinned with a circular cross-section at the front end and a square cross-section at the base end side, and the corners of the square are connected with a thin skin, and the lower edge of the thin skin is connected. A cut is made in the four sides of the plastic cage, and a groove having a concave cross section is provided on the intermediate surface of the plastic bag. The article clamping area on the distal end side is narrowed on the distal end side and the proximal end side is thickened. A plastic disposable chopstick, characterized by providing a stepped annular groove, wherein two plastic baskets having a distal end side of a circular cross-section and a base end side of a square cross-section are arranged in parallel, Are connected with a thin skin, provided with a groove having a concave cross section on the four surfaces of the intermediate portion, and provided with a plurality of annular grooves in the article sandwiching region on the distal end side, Between the circular part, it is a square with a corner arc of almost the same cross section, and a concave groove that spans the entire length. This is a plastic disposable chopstick that is provided with two plastic baskets that are thin with a circular cross-section at the front end and a square cross-section at the base end, and the corners of the square are connected with a thin skin. In addition, a triangular incision is made in the lower edge of the thin skin, a groove having a concave cross section is provided on the four sides of the intermediate portion of the plastic bag, the article sandwiching area on the distal end side is narrowed on the distal end side, and the proximal end side The section is provided with a plurality of annular grooves, and between the base-side square portion and the tip-side circular portion is a square of a corner arc of substantially the same cross section, It is a plastic disposable chopstick characterized by having a recessed and isolated groove.
この考案は箸の基部の角形の隅部を薄皮で連結したので、比較的破断し易くなっている。ここに角形とは、三角、四角、五角、六角及び八角形その他の多角形をいう。また薄皮の下縁(箸の先端側に近い方)に切込みを入れたから、両箸の分離(従って薄皮の破断)がきわめて容易となった。 In this device, the square corners of the base of the chopsticks are connected with a thin skin, so that it is relatively easy to break. Here, the term “square” refers to a triangle, a square, a pentagon, a hexagon, an octagon, and other polygons. In addition, since a cut was made in the lower edge of the thin skin (closer to the tip of the chopsticks), separation of both chopsticks (thus breaking the thin skin) became extremely easy.
次に平面部へ凹状の溝を設けたので、比較的使用材料が少なくて、曲げに強い特性がある。また先端側を断面円形にしたので、二本の箸の向きがどのようであろうと、物を均等に挟むことができる。 Next, since the concave groove is provided in the flat portion, the material used is relatively small, and there is a characteristic that it is strong against bending. In addition, since the tip side has a circular cross section, objects can be sandwiched evenly regardless of the orientation of the two chopsticks.
前記凹状の溝は、強度を勘案して深くし、可及的に少ない材料で箸を製造することができる。 The concave groove is deepened in consideration of strength, and chopsticks can be manufactured with as little material as possible.
この考案に使用する合成樹脂は、ポリプロピレン、ポリエチレン、ポリカーボネイトの外、とうもろこし、さとうきび、じゃがいもから得た樹脂(生分解性樹脂)又はプラスチック同様に、成型が可能なEペレット(北越製紙グループ開発の上白古紙51%以上を含有させた新素材)、その他毒性がなく、強度のある合成樹脂は使用することができる。前記において、合成プラスチックは再生することができると共に、生分解性樹脂は燃焼値が低く(例えば200℃)ダイオキシンが発生しないし、原料に毒性がない。また放置(又は人工的に)すれば微生物に分解されるので、環境衛生上優れている。また、何れも水と油に耐性がある。 Synthetic resins used in this invention are polypropylene, polyethylene, polycarbonate, corn, sugarcane, potato-derived resin (biodegradable resin) or plastic, which can be molded E pellets (developed by the Hokuetsu Paper Group) New materials containing 51% or more of white paper) and other non-toxic and strong synthetic resins can be used. In the above, the synthetic plastic can be regenerated, the biodegradable resin has a low combustion value (for example, 200 ° C.), no dioxin is generated, and the raw material is not toxic. Further, if left untreated (or artificially), it is decomposed into microorganisms, which is excellent in terms of environmental hygiene. Both are resistant to water and oil.
この考案によれば、基端の角形の隅部を、薄皮で連結したので、先端側を開くことにより容易に前記薄皮を破断することができる。 According to this device, since the square corners of the base end are connected by the thin skin, the thin skin can be easily broken by opening the distal end side.
また薄皮の下縁へ切込みを入れたので、薄皮の原味に拘らず容易に破断できる効果がある。 Further, since the cut is made in the lower edge of the thin skin, there is an effect that it can be easily broken regardless of the original taste of the thin skin.
次に二面又は四面へ凹入溝を設けたので、比較的少ない材料で十分の強度を有する箸を得ることができる。 Next, since the recessed grooves are provided on two or four sides, a chopstick having sufficient strength can be obtained with a relatively small amount of material.
この考案は、先端側を断面円形にして細くし、基端側を断面角形として太くしたプラスチック杆を二本並列し、前記基端から1cm程の隅部を薄皮で連結すると共に、該薄皮の下縁に三角状の切込みを入れ、中間部の隅部は孤状に形成し、平面部には断面凹状の溝を設け、前記先端側の物品挟着域は、先端側を細くし、基端側を太くして該部に複数段の環状溝を設け、前記基端側の角形部と、先端側の円形部との間はほぼ同一断面形状としてこの考案のプラスチック製割箸を構成した。 In this device, two plastic rivets with a distal end side having a circular cross section and a base end side having a square cross section are juxtaposed, and a corner of about 1 cm from the base end is connected with a thin skin, and the thin skin is A triangular incision is made in the lower edge, the corner of the middle part is formed in an isolated shape, a groove having a concave cross section is provided in the flat part, and the article clamping area on the tip side is made narrower on the tip side. The plastic side chopsticks of the present invention were configured so that the end side was thickened and a plurality of annular grooves were provided in the part, and the square part on the base end side and the circular part on the tip end side had substantially the same cross-sectional shape.
この考案の実施例を図1、2に基づいて説明すると、プラスチック杆1、1の基端に1cm程の正方形部2、2を設け、先端部ほぼ4cm程に挟着部4、4を設け、挟着部4、4は基端側を太くし、先端側を細く、その間の側壁に環状溝3、3を設け、前記正方形部2、2と、前記挟着部4、4との中間部5、5は、隅部を円孤状9に形成し、平面部に断面凹孤状の溝6、6を設け、前記方形部2、2の隅部を、薄皮7で接続し、薄皮7の下縁に切込み8を設けて、この考案のプラスチック製割箸10を得た。
An embodiment of the present invention will be described with reference to FIGS. 1 and 2. A
前記実施例において、先端側の一部で点接着してある。これは、機械による自動包装に際し、二本のプラスチック杆が正しく並列しているようにした為である。またプラスチック杆の中間部は断面ほぼ方形であるが、三角形〜八角形その他の多角形の何れも採用することができる。また溝6の深さは更に深くしても、浅くしてもよく、何れもこの考案に属するものである。
In the above embodiment, point bonding is performed at a part of the tip side. This is due to the fact that two plastic baskets are correctly aligned in automatic packaging with a machine. The intermediate portion of the plastic basket has a substantially square cross section, but any of triangular to octagonal and other polygons can be adopted. Further, the depth of the
