Description

この発明は、天ぷらを揚げる等の業務用として或いは家庭用として食用油を配達するとともに、その廃油を都合良く回収できるようにした食用油の配達兼廃油の回収ケースに関する。   The present invention relates to a edible oil delivery and waste oil recovery case that delivers edible oil for business use such as frying tempura or for household use, and the waste oil can be conveniently recovered.

食用油業者は、それを購入する食品の加工業者や飲食店等の顧客に対して、従来、一般的に一斗缶等の金属製の容器で配達していた。この場合であると、顧客には空いた同じ容器に廃油を詰めて貰い、それで廃油を引き取っていたが、廃油で汚れた金属製容器の処分が困難であった。そこで、最近では、金属製の容器の代わりに焼却等により廃棄処分しやすい段ボールケースを使用し、ポリ袋に小分けしピロー包装された食用油をそれで配達し、顧客では帰り荷としての廃油を別途用意されたポリ袋に入れて同じ段ボールケースに詰めていた。   In the past, edible oil traders have generally delivered them to customers such as food processors and restaurants that purchase them in metal containers such as cans. In this case, the customer filled the waste container with waste oil and picked up the waste oil, but it was difficult to dispose of the metal container dirty with the waste oil. Therefore, recently, instead of metal containers, we used cardboard cases that are easy to dispose of by incineration, etc., and delivered edible oil that was divided into plastic bags and packaged in pillows, and customers separately supplied waste oil as return goods. It was packed in the same cardboard case in a prepared plastic bag.

しかし、上記のように段ボールケースを使用すると、廃油を引き取った後の段ボールケースの始末が容易であるが、帰り荷では単独の別途ポリ袋を使用するために廃油の詰め込みが容易ではなかった。しかも、使い終わった廃油は、作業手順の要領から天ぷらを揚げた直後にポリ袋に投入されることがあり、そのとき廃油が180°C程度にも達していると、特に袋のシール部が高熱で破損しやすく、この危険を避けて温度が下がるまで放置した後に詰め込むとすると、天ぷらを揚げる手順の段取りが悪くなる等の問題があった。   However, when the corrugated cardboard case is used as described above, it is easy to clean the corrugated cardboard case after collecting the waste oil, but it is not easy to pack the waste oil because a separate plastic bag is used for return cargo. In addition, waste oil that has been used may be put into a plastic bag immediately after frying the tempura from the procedure of the work procedure. At that time, if the waste oil reaches about 180 ° C, the seal part of the bag is If it is stuffed after being left to stand until the temperature drops to avoid this danger, there is a problem that the procedure for frying the tempura is poor.

この発明は、上記のような実情に鑑みて、焼却処分し得る段ボールケースを使用しピロー包装で配達するものではあるが、帰り荷として別途袋を容易する必要がなく、しかも付属の袋に廃油を都合良く詰めることができ、それが180°C程度の高温であってもそれに耐えることのできる食用油の配達兼廃油の回収ケースを提供することを課題とした。   In view of the above circumstances, the present invention uses a corrugated cardboard case that can be incinerated and is delivered in pillow packaging. However, it is not necessary to make a separate bag as a return package, and waste oil is contained in an attached bag. It is an object of the present invention to provide an edible oil delivery and waste oil recovery case that can be conveniently packed and can withstand high temperatures of about 180 ° C.

上記の課題を解決するために、この発明は、食用油を小分けしたピロー包装油を輸送する食用油の配達兼廃油の回収ケースにおいて、上部に廃油を注入注出するキャップ付きスパウトが設けられるケース本体としての段ボール製の外箱と、そのスパウトから帰り荷の廃油が詰め込まれる樹脂製の内袋とからなり、内袋は、樹脂フィルムのチューブの両端をシールしてなる密閉された平袋であって、一端部近くの平型の上面に前記スパウトが突出して接続され、外箱の底にピロー包装油を受け得るよう中敷き状に敷きつめるとともに両端部を前後両面壁に沿って立ち上げて内装され、外箱の上部に開けた口孔にスパウトが嵌着され、スパウトからの廃油の注入時に内袋両端のシール部が外箱の上端部に常時保持されるように外箱の前後両面壁に内袋を接着し、該シール部の立上げを保持したままシール部よりも下方の外箱内に充満して内袋に廃油が充填されるように構成したことを特徴とする食用油の配達兼廃油の回収ケースを提供する。   In order to solve the above-mentioned problems, the present invention provides a edible oil delivery / waste oil recovery case for transporting pillow packaging oil into which edible oil is subdivided, wherein a spout with a cap for injecting and pouring the waste oil is provided at the top. It consists of a cardboard outer box as the main body and a resin inner bag filled with waste oil returned from the spout. The inner bag is a sealed flat bag made by sealing both ends of the resin film tube. The spout protrudes and is connected to the upper surface of a flat mold near one end, and is placed in an insole to receive pillow wrapping oil on the bottom of the outer box, and both ends are raised along the front and rear walls. The front and back sides of the outer box are fitted so that the spouts are fitted in the mouth holes opened in the upper part of the outer box and the seals at both ends of the inner bag are always held at the upper end of the outer box when injecting waste oil from the spout. On the wall A edible oil delivery function characterized in that the bag is bonded and filled in the outer box below the seal part while the rising of the seal part is maintained, and the inner bag is filled with waste oil. Provide waste oil recovery cases.

食用油の配達兼廃油の回収ケースを上記のように構成したから、これを配達に使用するときには、ピロー包装油を外箱の内袋敷きの上に重ね蓋を閉じて包装し、帰り荷に使用するときには、蓋を閉じた状態でスパウトから廃油を注入する。この時、廃油を外箱の上部に達する手前で止めて注入すると、内袋の両端のシール部が立ち上がり、シール部が外箱の上部に位置しているため、廃油が高いシール部に達することはない。したがって、これが使用の原則であるが、仮に満タン近くに誤って充填したとしても、廃油はシール部に破損を招くような高圧にはならない。なお、本願においてはスパウトがフラップに接続されている側を前側壁とする。   The edible oil delivery / waste oil recovery case is configured as described above. When using this for delivery, pillow packaging oil is wrapped on the inner bag of the outer box with the lid closed, and returned to the home. When using, inject waste oil from the spout with the lid closed. At this time, if the waste oil is stopped before reaching the top of the outer box and injected, the seals at both ends of the inner bag rise and the seals are located at the top of the outer box, so that the waste oil reaches the high seal part. There is no. Therefore, although this is a principle of use, even if it is accidentally filled near the full tank, the waste oil does not become a high pressure that causes damage to the seal portion. In the present application, the side where the spout is connected to the flap is defined as the front side wall.

以上説明したように、この発明の食用油の配達兼廃油の回収ケースによれば、焼却処分し得る段ボールケースを使用しピロー包装で配達するものであるが、内袋の付属でピロー包装油の安全な輸送形態が得られることはもちろん、帰り荷としての廃油をその付属の内袋に注入して都合良く詰めることができ、それが180°C程度の高温で注入されたとしても、それが高所のシール部に達しないことから、高温によりシール部が破損を被ることはなく、極めて安全に廃油の充填および輸送をなすことができるという優れた効果がある。その他、次のような効果を併有する。   As described above, according to the edible oil delivery and waste oil recovery case of the present invention, it is delivered in pillow packaging using a corrugated cardboard case that can be incinerated. Of course, a safe transportation form can be obtained, and the waste oil as a return can be poured into the attached inner bag and packed conveniently. Even if it is injected at a high temperature of about 180 ° C, Since the seal portion does not reach the high place, the seal portion is not damaged by high temperature, and there is an excellent effect that the waste oil can be filled and transported extremely safely. In addition, it has the following effects.

(1)従来の食用油の輸送と共に、そのまま段ボール外箱が廃油容器としても使用できる内袋との一体構造であり、内袋が一体化されているため、高温の廃油を入れるとき、外箱と袋が外れて起きる火傷などの怪我を防止でき、また、袋を段ボール箱にセットするための手間が省ける。
(2)段ボール外箱の幅面に中折り線を設けることで(請求項2)、また、内フラップのコーナー部を切り取ることでスパウトから廃油を入れるときの障害になることもなく好都合である。
(3)スパウトの成形樹脂と同じ樹脂において内袋の基底鍔を挟んで接着することで、内袋とスパウトとの接着強度が得られ、また、平袋形の単純形状にすることで(請求項3)、シール部を耐熱性ナイロン等の融着で耐熱に実現し、液漏れ等の安全性を高めた。
(4) 内袋を余裕のある幅にしたので(請求項4)、適正な容量を入れることが可能となった。
(1) Along with the conventional transportation of edible oil, the cardboard outer box is an integral structure with the inner bag that can also be used as a waste oil container, and the inner bag is integrated. Injuries such as burns that occur when the bag comes off can be prevented, and the trouble of setting the bag in the cardboard box can be saved.
(2) It is convenient to provide a middle fold line on the width surface of the corrugated cardboard outer box (Claim 2), and to cut out the corner portion of the inner flap without causing an obstacle when putting waste oil from the spout.
(3) Adhesion strength between the inner bag and the spout can be obtained by bonding the inner bag with the base bag in the same resin as the spout molding resin. Item 3), the seal part is made heat-resistant by fusing heat-resistant nylon, etc., and safety such as liquid leakage is improved.
(4) Since the inner bag has a sufficient width (Claim 4), it is possible to insert an appropriate capacity.

この発明における食用油の配達兼廃油の回収ケースPは、段ボール製の外箱1とそれに常時内装される付属の内袋3とからなり、内袋3は、行きはピロー包装油5のクッションとなり、帰りはスパウト6から注入される廃油7の入れ物となるものであるであるが、廃油の高熱によっても破損しない巧みな構造にと開発した。   The edible oil delivery / waste oil recovery case P in the present invention comprises a corrugated outer box 1 and an attached inner bag 3 that is always installed therein, and the inner bag 3 serves as a cushion for the pillow packaging oil 5. The return is a container for the waste oil 7 injected from the spout 6, but has been developed into a clever structure that will not be damaged by the high heat of the waste oil.

外箱1は、焼却処分できる紙段ボール又は樹脂段ボール製であって、段ボール構造は、特に限定するものではなく、一層段ボールのほか、二層段ボール等が主であるが、特に二層段ボールが強度的に望ましい。箱型については、原則的にはA式で、また、それに類した構造が殊にピロー包装油5の出し入れ(図3参照)の都合から望ましい。   The outer box 1 is made of paper corrugated cardboard or resin corrugated cardboard that can be disposed of by incineration, and the corrugated cardboard structure is not particularly limited. In addition to single-layer corrugated cardboard, two-layer corrugated cardboard is mainly used. Is desirable. As for the box type, in principle, the formula A is used, and a similar structure is desirable particularly for the convenience of taking in and out the pillow packaging oil 5 (see FIG. 3).

内袋3は、樹脂のチューブフィルムの両端にシール部33,34を形成した密閉形の平袋が原型であって、その一端部の上面に注出注入口としての樹脂製のスパウト6を取り付ける接続孔13が開けられる。両シール部33,34は、この接続孔13のスパウト6と共に高く立ち上げられ上端部に配置されることから、要所が高熱の廃油にも触れることなく安全に耐えることになる。   The inner bag 3 is a prototype of a sealed flat bag in which seal portions 33 and 34 are formed at both ends of a resin tube film, and a resin spout 6 as a pouring inlet is attached to the upper surface of the one end portion. The connection hole 13 is opened. Since both the seal portions 33 and 34 are raised up together with the spout 6 of the connection hole 13 and are arranged at the upper end portion, the important portions can endure safely without touching high-temperature waste oil.

内袋3の平袋幅Wについては、廃油7の圧力で膨出したときに外箱1の下半部に隅々まで納まり良くするために、左右に外箱1の内幅、つまり両面壁21,21の幅よりも左右に余りα,αが生じるようにやゝ幅広く形成する。しかし、外箱1の中に上までだぶつくようではシール部33,34がそれに没するので、常識的な内周となるように幅Wの大きさにも制約した。つまり、廃油7を入れたときに、上部に空き15(図5)が生じるように膨出したときの内周が設定される。   As for the flat bag width W of the inner bag 3, the inner width of the outer box 1 on the left and right sides, that is, double-sided walls, in order to make it fit all the way into the lower half of the outer box 1 when bulging with the pressure of the waste oil 7 It is formed slightly wider so that more α and α are generated on the left and right than the width of 21 and 21, respectively. However, since the seal portions 33 and 34 are immersed in the outer box 1 so as to bump up to the top, the size of the width W is also constrained to be a common sense inner periphery. That is, when the waste oil 7 is added, the inner circumference when the bulge is generated so that a vacant space 15 (FIG. 5) is generated in the upper portion is set.

内袋3は、基本的には一重であるが、強度的安全性を確保するために、内外チューブフィルム35と36からなる二重構造とすることができる(請求項3参照)。さらなる対策として強度的安全性を確保するためは、それぞれのチューブフィルム35,36について、樹脂材質の異なるラミネート構造とする。また、このようにすることにより、高熱に対する強度を確保するほかに、スパウト6の成形樹脂の材質に合わせてそれに接着しやすくできる(請求項3)。この点でも安全性に万全を期しうる。   The inner bag 3 is basically single, but can have a double structure composed of inner and outer tube films 35 and 36 in order to ensure strength and safety (see claim 3). In order to ensure the strength and safety as a further measure, the tube films 35 and 36 have a laminate structure made of different resin materials. Moreover, by doing in this way, besides ensuring the intensity | strength with respect to high heat, it can be made easy to adhere | attach to it according to the material of the molding resin of the spout 6 (Claim 3). In this respect, safety can be ensured.

内袋3の樹脂フィルムの材質については、ナイロン、ナイロンとポリエチレンとのラミネートフィルム、ポリエチレンテレフタレート(PET)、アルミ箔を入れたラミネートフィルム、その複合フィルムや機能性フィルム等が好適に使用できるが、特に限定するものではない。実験では、特に、ナイロンとポリエチレンまたはナイロンとポリプロピレンのラミネートフィルムが好ましかった。また、ナイロンは高熱に耐えやすく殊に6ナイロンが安価でより好ましい。   As for the material of the resin film of the inner bag 3, nylon, a laminate film of nylon and polyethylene, polyethylene terephthalate (PET), a laminate film containing aluminum foil, a composite film or a functional film thereof can be suitably used. There is no particular limitation. In the experiment, a laminate film of nylon and polyethylene or nylon and polypropylene was particularly preferred. Nylon is easy to withstand high heat, and 6 nylon is particularly preferable because it is inexpensive.

スパウト6は、注入注出の筒口6aを外箱1に固定しキャップ20で密栓できる構造であれば特に限定するものではないが、次の実施例および請求項3で示すようにしてスパウト6との接続について高熱に対応するものとすることができる。   The spout 6 is not particularly limited as long as it has a structure in which the injection / pouring barrel 6a can be fixed to the outer box 1 and sealed with the cap 20, but as shown in the following examples and claims 3, It is possible to cope with high heat in connection.

図面は、一実施例を示したものであるが、特に内袋3のフィルム構造については、微細な図示は不可能であるため概略して示す箇所もある。つまり、このケースPは、A式段ボール箱の外箱1に二重構造の内袋3が内装されるが(図6,図7)、二重構造を図1,図3,図4,図5では単に一重で示すこととし、詳細には図7で説明的に拡大してラミネート構造を図示した。但し、この発明では一重の一般構造の樹脂袋を除外するものではない。   Although the drawings show one embodiment, there is a portion schematically shown because the film structure of the inner bag 3 is not particularly finely illustrated. That is, in this case P, the inner bag 3 having a double structure is housed in the outer box 1 of the A-type cardboard box (FIGS. 6 and 7). In FIG. 5, only a single layer is shown, and in detail, the laminate structure is illustrated in an enlarged manner in FIG. However, this invention does not exclude a single-layered resin bag having a general structure.

外箱1は、A式として胴部について、左右両側壁19,19と前後両面壁21,21とが交互に配列され、両側壁19,19の上下両端に内フラップ23,23が、両面壁21,21の上下両端に外フラップ25,25がそれぞれ連設され、一端の糊代27により組まれる。そのうち前側の外フラップ25にスパウト6を嵌着する口孔29が設けられる。外フラップ25にはこの部分にスパウト6とともに内袋3のフィルムが下方から集合するように張りつく。そこで、外フラップ25を閉じたときに、その妨げにならないように左右内フラップ23,23には切欠31,31が設けられる。なお、外箱1の包装状態の組立てでは粘着テープが要所に張られるが、この図示は省略する。また、外箱1の胴部壁はいずれも側壁であるが、説明の都合上、左右両側壁19,19と前後両面壁21,21という表示で区分けした。   As for the outer case 1, the left and right side walls 19 and 19 and the front and rear side walls 21 and 21 are alternately arranged with respect to the body as the A type, and the inner flaps 23 and 23 are provided on the upper and lower ends of the side walls 19 and 19, respectively. Outer flaps 25 and 25 are connected to upper and lower ends of 21 and 21, respectively, and assembled by a glue margin 27 at one end. A mouth hole 29 for fitting the spout 6 is provided in the outer flap 25 on the front side. The film of the inner bag 3 is stuck to the outer flap 25 together with the spout 6 from this position. Therefore, the left and right inner flaps 23 and 23 are provided with notches 31 and 31 so as not to obstruct the outer flap 25 when the outer flap 25 is closed. In addition, in the assembly of the outer box 1 in the packaged state, an adhesive tape is stretched at a key point, but this illustration is omitted. Moreover, although the trunk | drum wall of the outer case 1 is a side wall, for convenience of explanation, the left and right side walls 19 and 19 and the front and rear side walls 21 and 21 are separated.

内袋3は、基本的にはチューブフィルムの両端に熱溶着でシール部33,34を設けて偏平な平袋の密閉形式であるが、この実施例では耐熱性を高度に確保するために、内外チューブフィルム35,36からなる二重とするとともに、その両チューブフィルム35,36を材質の異なる2樹脂からなるラミネート構造とした。そして、接続孔13の口縁部における内外チューブフィルム35,36のラミネートフィルムでスパウト6の基底鍔37を挟ませそれに溶着した。具体的には次の通り図7について説明する。   The inner bag 3 is basically a flat flat bag hermetically sealed by heat sealing at both ends of the tube film, but in this embodiment, in order to ensure a high degree of heat resistance, The tube film 35 and 36 are made of a double layer made of inner and outer tube films 35 and 36, and both the tube films 35 and 36 have a laminate structure made of two resins of different materials. Then, the base rod 37 of the spout 6 was sandwiched between the laminated films of the inner and outer tube films 35 and 36 at the rim of the connection hole 13 and welded thereto. Specifically, FIG. 7 will be described as follows.

内袋3を構成する内外チューブフィルム35,36のうち、内チューブフィルム35は、廃油が直接触れるために内側材35aを耐熱性に優れた性質を有するナイロン樹脂となし、外側材35bをポリエチレン樹脂として構成される。他方外チューブフィルム36は、逆に外側材36aがナイロン樹脂に、内側材36bがポリエチレン樹脂となっている。つまり、内外両チューブフィルム35,36の間では、ポリエチレン樹脂が離反可能に接合している。   Of the inner and outer tube films 35 and 36 constituting the inner bag 3, the inner tube film 35 is made of a nylon resin having an excellent heat resistance property because the waste oil is directly touched, and the outer member 35 b is a polyethylene resin. Configured as On the other hand, the outer tube film 36 has an outer material 36a made of nylon resin and an inner material 36b made of polyethylene resin. That is, the polyethylene resin is detachably joined between the inner and outer tube films 35 and 36.

内袋3のシール部33と34は、端のシール部33a,34aとその内側のシール部33b,34bとの二段の配列に形成され(図6)、廃油の漏れを二段に防止する対策が講じられる。また、内袋3の平袋幅Wについては、前後両面壁21,21の両側に余りα,αができ幅Wの中央部に幅広い間隔で2条の折り目40,40が形成され、外箱1の折り畳み(中折り線43,43による)に順応して変形しやすくしてある。   The seal portions 33 and 34 of the inner bag 3 are formed in a two-stage arrangement of end seal portions 33a and 34a and inner seal portions 33b and 34b (FIG. 6) to prevent waste oil leakage in two steps. Measures are taken. Further, with respect to the flat bag width W of the inner bag 3, there are excess α and α on both sides of the front and rear side walls 21 and 21, and two folds 40 and 40 are formed at a wide interval at the center of the width W. It is easy to deform in conformity with 1 fold (by the middle fold lines 43, 43).

スパウト6は、ポリエチレン樹脂で成形され、短筒の筒口6aを主体とするものであるが、この実施例では、口皿39の中央に筒口6aを設け、口皿39の底部の延長に基底鍔37が突設される。また、口皿39の上端に短い縁鍔42が突設され、この縁鍔42を外箱1の口孔29に内側から通して嵌着される。通しやすく口孔29の周囲には放射状に多数の切溝が形成される(図1参照)。なお、キャップ20は筒口6aの上端に密嵌される構造となっている。   The spout 6 is formed of a polyethylene resin and mainly includes a short tube opening 6a. In this embodiment, the spout 6 is provided with a tube opening 6a at the center of the mouth plate 39, and the base portion is extended to the bottom of the mouth plate 39. 37 is projected. Further, a short edge collar 42 projects from the upper end of the mouth plate 39, and the edge collar 42 is fitted into the mouth hole 29 of the outer box 1 from the inside. A large number of kerfs are formed radially around the hole 29 for easy passage (see FIG. 1). The cap 20 is structured to be tightly fitted to the upper end of the tube opening 6a.

スパウト6の取付けについては、内袋3の上面に口皿39が通る接続孔13を開けるが、この場合、スパウト6のポリエチレン樹脂に対して内外チューブフィルム35,36のポリエチレン(35b,36b)が同樹脂材において一体化するので、強固な結合関係が生まれ、しかも、耐熱性に優れたナイロン(35a,36a)が被覆しているので、二重袋構造とも相まって耐熱・耐衝撃強度を保有する高度な安全性、信頼性を確保できる結果となった。   For the attachment of the spout 6, the connection hole 13 through which the mouth plate 39 passes is opened on the upper surface of the inner bag 3. In this case, the polyethylene (35b, 36b) of the inner and outer tube films 35, 36 is made to the polyethylene resin of the spout 6. Since it is integrated in the same resin material, a strong bonding relationship is born, and because it is coated with nylon (35a, 36a) with excellent heat resistance, it has heat resistance and impact strength strength combined with the double bag structure. As a result, it was possible to ensure a high level of safety and reliability.

図1は、外箱1と内袋3とを組み合わせる要領を示したもので、内袋3を平袋として図示の如くU字形に折り曲げながら外箱1に納め、両面壁21,21に接着する。このとき、余りα,αの部分は両側壁19,19に沿って折り曲げておくので、内袋3がピロー包装油5を囲むクッションとなる(図3)。なお、一方の端部3aは立ち上げに接着しても良いし(図4参照)、ピロー包装油5の上に折り重なるようにしても良い。左右両側壁19,19には幅中央に沿って上下内フラップ23,23にわたる中折り線43,43が設けてあるが、上記のような内袋3との組合せにおいて、両面壁21,21を合致させる合わせ折りの折り畳みの仕方が可能である。   FIG. 1 shows how to combine the outer box 1 and the inner bag 3. The inner bag 3 is folded into a U-shape as shown in the figure as a flat bag, and is put in the outer box 1 and bonded to the double-side walls 21 and 21. . At this time, since the remainders α and α are bent along the side walls 19, 19, the inner bag 3 becomes a cushion surrounding the pillow packaging oil 5 (FIG. 3). One end 3 a may be bonded to the start-up (see FIG. 4), or may be folded over the pillow packaging oil 5. The left and right side walls 19, 19 are provided with center fold lines 43, 43 extending along the center of the width across the upper and lower inner flaps 23, 23. It is possible to fold the mated folds to match.

図2は、ピロー包装油5の包装状態(図4)または廃油7の包装状態(図5)の外観を示したもので、内フラップ23,23の上に外フラップ25,25を重ねて蓋が閉じられるが、スパウト6が内フラップ23,23の切欠31,31の中に落ち込んでいる。   FIG. 2 shows the appearance of the packaging state of the pillow packaging oil 5 (FIG. 4) or the packaging state of the waste oil 7 (FIG. 5). The outer flaps 25, 25 are overlapped on the inner flaps 23, 23, and the lid Is closed, but the spout 6 falls into the notches 31 and 31 of the inner flaps 23 and 23.

図5は、廃油7の包装状態を示したものであるが、両面壁21,21の間の中央部では、廃油7を中途の高さ程度に入れることによって上に空き15が生じている。こうすることで、廃油7の液面との関係でシール部33,34の立ち上げを保持してある。なお、廃油7の波動の増幅を押さえるには内袋3の膨出内径を外箱1の内周より半減程度とする。これが廃油7の位置の安定性確保の観点から望ましい(図8,請求項4参照)。   FIG. 5 shows the packaging state of the waste oil 7. In the central portion between the double-side walls 21, 21, an empty space 15 is created by putting the waste oil 7 at a midway height. In this way, the start-up of the seal portions 33 and 34 is maintained in relation to the liquid level of the waste oil 7. In order to suppress the amplification of the wave motion of the waste oil 7, the bulging inner diameter of the inner bag 3 is set to about half of the inner circumference of the outer box 1. This is desirable from the viewpoint of securing the stability of the position of the waste oil 7 (see FIG. 8, claim 4).
