【発明の属する技術分野】
本発明は、飲食店や食品加工場の配水設備に設けられたゴミ受けカゴにセットして使用される水切り伸縮ネットに関する。
【０００２】
【従来の技術】
飲食店や食品加工場の配水設備、特にグリーストラップに設けられたゴミ受けカゴの清掃は大変な重労働である。この作業を軽減させる方法として、ゴミ受けカゴにセットして使用される伸縮ネットが提案されている（例えば、特開平９−１６５１０３号公報、特開２００１−１３０７０２号公報等）。
【０００３】
【発明が解決しようとする課題】
ところが、従来の伸縮ネットは目が詰まり易かったりまた反対にゴミを逃がしてしまうという問題点やゴミが溜まったネットをゴミ受けカゴから取り出すのに取り出し難いという欠点を有していた。
本発明は、ゴミ捕捉性と水切れ性との両者を満足し、且つゴミがゴミ受けカゴいっぱいに溜まった状態でもゴミ受けカゴから取り出しやすい水切り伸縮ネットを提供することを目的とする。
【０００４】
【課題を解決するための手段】
本発明は合成繊維マルチフィラメントからなるラッセル編みの目の形状が６角形の、グリーストラップのゴミ受カゴ用編目状袋体であって、上記６角形の１辺の長さが１．５〜２．１ｍｍである水切り伸縮ネットである。
以下、本発明について詳細に説明する。
先ず、本発明の水切り伸縮ネットはポリエステル、ポリアミド、ビニロン、ポリプロピレン等の合成繊維のマルチフィラメントからなり、ラッセル編み等の縦編み機でネット状の構造体を形成させる。このネットの底部を閉じて袋体として伸縮水切りネットを作成する。この方法で作成した伸縮ネットは、ネットの横方向には伸びるがネットの深さ方向には伸びない。この特徴は、各種サイズの異なるゴミ受けに使用出来る一方、ゴミがゴミ受けカゴいっぱいまで溜まった状態でもネットが深さ方向には伸びないのでゴミ受けカゴから取り出しやすい。
【０００５】
特にダブルラッセル編機で筒状または底部を封じた袋状の構造まで形成するのが生産性の面からは好ましい。
次に、本発明の水切り伸縮ネットは目の形状が６角形の編目状袋体である。６角形にすることによってネットの強度が強くなるとともに、伸縮性も最大になる。また、ゴミ捕捉性と水切れ性とのバランスが取り易い。
そして上記６角形の１辺の長さは１．５〜２．１ｍｍである。１．５ｍｍよりも小さいと油脂類や米糠等が目に詰まって水切り性に劣り、また２．１ｍｍよりも大きいとご飯粒や天カス等のゴミが捕捉できない。好ましくは、Ｌが１．７〜１．９ｍｍの場合である。
【０００６】
【発明の実施の形態】
本発明について、以下具体的に説明する。
先ず、各評価方法について説明する。
（１）目の大きさ（Ｌ：単位ｍｍ）
水切り伸縮ネットを、目の構造が６角形の形状を維持した状態で最大に引き伸ばした状態で拡大率１０倍の写真を３枚とり、各写真から１０個、計３０個の６角形の目の各辺の長さを測定して平均値Ｌを求めた。
【０００７】
（２）ゴミ捕捉性
・方法
容量２０リットル、有効容量１５リットル、長さ４２０ｍｍ、幅２００ｍｍ、深さ２４０ｍｍの透明アクリル製の容器に、長さ方向に３当分する位置２カ所に、底部から４０ｍｍ開けて仕切板を設け（３槽構造にした）、更に前記仕切板２枚の中間位置に底部に固定した高さ４５ｍｍの仕切板を設け、また、排水が流れ込んでくる槽には、長さ９０ｍｍ、幅１５０ｍｍ、深さ１２０ｍｍで直径５ｍｍの穴が開いているステンレス製板を貼り付けたゴミ受けカゴを取り付けた小型のグリーストラップを作成した。また米糠２００ｇ、天カス５００ｇ、ゴマ油１リットルを加えた水（モデル排水と呼ぶ）４０リットルを攪拌装置付きのタンクに入れたものを準備した。モデル排水は予め２５±２℃で１時間攪拌しておいた。評価する水切り伸縮ネットをゴミ受けカゴにセットし、上記タンクからモデル排水を２．５リットル／分の速度で１時間流して、水切り伸縮ネットのゴミ捕捉性を観察した。
（３）水切れ性
・方法
ゴミ捕捉性と同様な方法で評価した。
（４）引上げ性
・方法
ゴミ捕捉性の評価の要領で、モデル排水を１時間流した後、ゴミ受けカゴにセットしておいた水切り伸縮ネットを取り出した。
【実施例１】
東レ社製ポリエステルマルチフィラメント１１０Ｔ−１２−３００ＢＯブライト系をダブルラッセル編機で編んで、表１に示す水切り伸縮ネット３種（Ｒｕｎ．Ｎｏ．１〜３）を作成した。
【００１１】
【比較例１】
実施例１と同様に東レ社製ポリエステルマルチフィラメント１１０Ｔ−１２−３００ＢＯブライト系をダブルラッセル編機で編んで、表１に示す水切り伸縮ネット２種（Ｒｕｎ．Ｎｏ．４，５）を作成した。
以上、Ｒｕｎ．Ｎｏ．１〜５の水切り伸縮ネットの評価結果を表１にまとめて示す。
表１において、Ｒｕｎ．Ｎｏ．１〜３の本発明の水切り伸縮ネットは、ゴミ捕捉性、水切り性及び引上げ性全てにおいて優れていた。
ここで、Ｒｕｎ．Ｎｏ．１とＲｕｎ．Ｎｏ．４との比較において、ネットの６角形の編目の１辺の長さ（Ｌ）が１．５ｍｍ以上であることが、水切り性が実用レベル以上の性能を保持する上で重要なことが分かる。
また、Ｒｕｎ．Ｎｏ．３とＲｕｎ．Ｎｏ．５との比較において、Ｌが２．１ｍｍ以下であることが、ゴミ捕捉性が実用レベル以上の性能を保持する上で重要なことが分かる。
また、Ｒｕｎ．Ｎｏ．２の水切り伸縮ネットはゴミ捕捉性と水切り性とが共に優れており、ゴミ捕捉性と水切り性とが共に優れている範囲はＬが１．７〜１．９ｍｍであることが実験から分かった。

本発明の水切り伸縮ネットは、ゴミ捕捉性と水切れ性との両者を満足し、且つゴミがゴミ受けカゴいっぱいに溜まった状態でもゴミ受けカゴから取り出しやすい。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a draining telescopic net used by being set in a garbage receiving basket provided in a water distribution facility of a restaurant or a food processing plant.
[0002]
[Prior art]
Cleaning the water distribution facilities at restaurants and food processing plants, especially the garbage bins installed in grease traps, is a heavy labor. As a method for reducing this work, there have been proposed telescopic nets that are used by being set in a garbage receiving basket (for example, JP-A-9-165103, JP-A-2001-130702, etc.).
[0003]
[Problems to be solved by the invention]
However, conventional stretchable nets have the problem that they are easily clogged, and on the other hand, dust is allowed to escape, and that it is difficult to take out the net with accumulated dust from the garbage receiving basket.
SUMMARY OF THE INVENTION An object of the present invention is to provide a draining stretchable net that satisfies both the dust catching property and the water drainage property, and that can be easily taken out from the dust receiving basket even when the dust is accumulated in the garbage receiving basket.
[0004]
[Means for Solving the Problems]
The present invention is a stitch bag for a dust trap of a grease trap having a hexagonal shape of a Russell knitting made of synthetic fiber multifilament, wherein the length of one side of the hexagon is 1.5-2. It is a draining telescopic net that is 1 mm.
Hereinafter, the present invention will be described in detail.
First, the draining stretchable net of the present invention is composed of multifilaments of synthetic fibers such as polyester, polyamide, vinylon, polypropylene and the like, and a net-like structure is formed by a warp knitting machine such as Russell knitting. The bottom of this net is closed to create a stretchable draining net as a bag. An elastic net created by this method extends in the horizontal direction of the net but does not extend in the depth direction of the net. While this feature can be used for garbage receptacles of various sizes, the net does not extend in the depth direction even when the garbage has accumulated up to the garbage receptacle basket, so it can be easily taken out from the garbage receptacle basket.
[0005]
In particular, it is preferable from the viewpoint of productivity to form a cylindrical structure or a bag-shaped structure with the bottom sealed with a double raschel knitting machine.
Next, the draining stretchable net of the present invention is a knitted bag having a hexagonal eye shape. The hexagonal shape increases the strength of the net and maximizes the stretchability. Moreover, it is easy to balance the dust catching property and the water draining property.
The length of one side of the hexagon is 1.5 to 2.1 mm. If it is smaller than 1.5 mm, oils and fats, rice bran and the like are clogged and inferior in draining property, and if it is larger than 2.1 mm, dust such as rice grains and scum can not be captured. Preferably, L is 1.7 to 1.9 mm.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be specifically described below.
First, each evaluation method will be described.
(1) Eye size (L: unit mm)
Three draining stretchable nets with the eye structure stretched to the maximum while maintaining the hexagonal shape, and taking three photos with a magnification of 10 times, 10 from each photo, a total of 30 hexagonal eyes The average value L was determined by measuring the length of each side.
[0007]
(2) Garbage trapping method ・ Method capacity: 20 liters, effective capacity: 15 liters, length: 420 mm, width: 200 mm, depth: 240 mm Opened and provided with a partition plate (three tank structure), a partition plate with a height of 45 mm fixed to the bottom at the middle position between the two partition plates, and a tank into which drainage flows A small grease trap having a dust receiving basket attached with a stainless steel plate having a hole of 90 mm, a width of 150 mm, a depth of 120 mm and a diameter of 5 mm was prepared. Moreover, what put 40 liters of water (referred to as model waste water) with 200 g of rice bran, 500 g of heavenly sludge and 1 liter of sesame oil in a tank equipped with a stirrer was prepared. The model waste water was previously stirred at 25 ± 2 ° C. for 1 hour. The draining elastic net to be evaluated was set in a garbage receiving basket, and the model waste water was allowed to flow from the tank at a rate of 2.5 liters / minute for 1 hour, and the dust trapping property of the draining elastic net was observed.
(3) Water drainage / method Evaluation was made in the same manner as the dust catchability.
(4) Pulling-up property / method In the procedure for evaluation of dust catching property, after draining the model waste water for 1 hour, the draining stretcher net set in the dust receiving basket was taken out.
