Description

【０００１】
【発明の属する技術分野】
本発明はインキ、マヨネーズ、ケチャップ等の高粘性の液体を収納し、液体自吸式機械に装着するカートリッジ液体用容器に関するものである。
【０００２】
【従来の技術】
従来より、例えば、高粘性のインキを充填した状態で液体自吸式機械としての簡易印刷機や複写機に装着するカートリッジ液体用容器が知られ、図２に示すように、四角の箱形状を成し、高粘性インキを吸引排出する抽出口（６）を前記箱形状の底部に設けた厚肉容器（１００）と、その厚肉容器（１００）と略同形状をなして厚肉容器（１００）の内側に収納され、そのフランジ部（８ａ）を厚肉容器（１００）のフランジ部（８）と融着せしめた薄肉容器（２００）とからなるもので、その薄肉容器（２００）が、表裏を反転させることによって内容物であるインキを確実に吸引排出可能のように設計されているものである。
【０００３】
また、図２に示すように、上記のカートリッジ液体容器（１）を液体自吸式機械の吸引部（８０）のノズル（８０ａ）に厚肉容器（１００）の底部（１４）の口部（６ａ）を挿入して前記底部（１４）が垂直になるように装着していた。
【０００４】
【発明が解決しようとする課題】
しかし、上記の従来技術においては、内容物が高粘性のため、口部（６ａ）近傍の内容物とともに口部（６ａ）近傍の薄肉容器（２００）を吸引し、厚肉容器（１００）の口部（６ａ）を塞ぎ、吸引不可能となり易いという問題点があった。また、内容物の重量が重いため、上記口部（６ａ）より上部の内容物は吸引排出されやすいが、口部（６ａ）より下部の内容物は吸引され難く、残液となるというごとき問題点があった。
【０００５】
また、薄肉の袋状容器に、抽出口を融着することによって、同様の効果を求めるカートリッジ液体用容器はあったが、吸引時の安定性に欠け、袋状容器本体が抽出口の口部に被さったり、袋状容器本体が吸引途中で括れ、吸引不可能となるなどの問題点があった。
【０００６】
本発明は、かかる従来技術の問題点を解決するものであり、その課題とするところは、液体自吸式機械に装着する厚肉容器（１００）と薄肉容器（２００）からなるカートリッジ液体用容器において、高粘性液体内容物を確実に吸引排出し、残液とならないカートリッジ液体用容器を提供することにある。
【０００７】
【課題を解決するための手段】
本発明に於いて上記課題を達成するために、まず請求項１の発明では、液体自吸式機械に装着する、四角形状の底板と、該底板の周縁辺より上方に伸びる２枚の対向する側面板と、該側面板と隣合う正面板と後面板とで箱形状を成し、前記底板と正面板とで形成される陵角部を切り欠いた切り欠面を設け、該切り欠面の略中央部外側に内容物を吸引排出する抽出口を設けた厚肉容器と、該厚肉容器と略相似形状を成して該厚肉容器の内側に収納され、その上縁開口部のフランジ部を厚肉容器の上縁開口部のフランジ部と融着せしめた薄肉容器とでなるカートリッジ液体容器において、前記厚肉容器の切り欠き面の内側で前記抽出口の開口された口部周縁辺に沿って上方に起立し、切り欠かれた開口部を有する略半円筒状のリブが該切り欠かれた開口部が前記後面板側に向いているように設けられ、該略半円筒状のリブより１方の側面板側にある切り欠き面内面上から底板内面上にかけて複数の細長いリブが設けられていることを特徴とするカートリッジ液体用容器としたものである。
【０００８】
また、請求項２の発明では、液体が充填され薄肉容器が前記厚肉容器より外側に広がった際、前記厚肉容器の細長いリブが設けられた側に相当する薄肉容器の側面板の上縁開口部から厚肉容器の底板に対向する薄肉容器の面の周縁辺までの高さが対向する薄肉容器の側面板の高さより小さいことを特徴とする請求項１記載のカートリッジ液体用容器としたものである。
【０００９】
また、請求項３の発明では、前記液体自吸式機械への装着が前記複数の細長いリブが設けられた側にある厚肉容器の一方の側面板が下側となるように成されていることを特徴とする請求項１または２記載のカートリッジ液体用容器としたものである。
【００１０】
【発明の実施の形態】
以下本発明の実施の形態を、図面を用いて詳細に説明する。
【００１１】
図１は、本発明のカートリッジ液体用容器全体を説明するための斜視図である。また、図２は、本発明に係わる従来のカートリッジ液体用容器の形態と液体自吸式機械への装着状態を略断面で表した説明図である。図３は、横倒し（機械に装着されたときの）状態の本発明のカートリッジ液体用容器に内容物が充填される前および吸引注出後の状態を示す正面図であり、図４は、内容物が充填された状態を示す正面図である。また、図５は、本発明のカートリッジ液体用容器に内容物が充填される前および吸引注出後の状態を示す側面図であり、図６は、内容物が充填された状態を示す側面図である。さらに図７は、本発明のカートリッジ液体用容器のリブの一実施の形態を説明する斜視図である。
【００１２】
本発明のカートリッジ液体用容器は、液体自吸式機械に装着するもので、まず図１、図６及び図７に示すように、四角形状の底板（１０）と、該底板（１０）の周縁辺より上方に伸びる２枚の対向する側面板（４０）と、該側面板（４０）と隣合う正面板（２０）と、後面板（３０）とで箱形状を成し、前記底板（１０）と正面板（２０）とで形成される陵角部を切り欠いた切り欠面（２０ａ）を設け、該切り欠面（２０ａ）の略中央部外側に内容物を吸引排出する抽出口（６）を設けた厚肉容器（１００）と、該厚肉容器（１００）と略相似形状を成して該厚肉容器（１００）の内側に収納され、その上縁開口部（４）のフランジ部（８ａ）を厚肉容器（１００）の上縁開口部のフランジ部（８）と融着せしめた薄肉容器（２００）とでなるカートリッジ液体容器において、前記厚肉容器（１００）の切り欠き面（２０ａ）の内側で前記抽出口（６）の開口された口部（６ａ）周縁辺に沿って上方に起立し、切り欠かれた開口部（５０ａ）を有する略半円筒状のリブ（５０）が該切り欠かれた開口部（５０ａ）が前記後面板（３０）側に向いているように設けられ、該略半円筒状のリブ（５０）より１方の側面板（４０）側にある切り欠き面（２０Ａ）内面上から底板（１０）内面上にかけて３個の細長いリブ（５２）が設けられていることを特徴とするものである。
【００１３】
また、請求項２の発明では、図４に示すように、上記細長いリブ（５２）が設けられた側に相当する薄肉容器（２００）の側面板（４２ａ）の高さ、すなわち側面板（４２ａ）側の深さが、その側面板（４２ａ）と対向する薄肉容器（２００）の側面板（４２ｂ）の高さ（薄肉容器（２００）の深さ）より小さいことを特徴とするカートリッジ液体用容器（１）である。
【００１４】
また、請求項３の発明では、図４に示すように、上記発明のカートリッジ液体用容器（１）が横倒しの状態で、すなわち上記細長いリブ（５２）が設けられた側にある厚肉容器（１００）の一方の側面板（４０）が下側となるように液体自吸式機械（図示せず）に装着されていることを特徴とするものである。
【００１５】
以上本発明のカートリッジ液体用容器（１）は、図３に示すように、高粘性のインキ等内容物が充填される前は、薄肉容器（２００）が厚肉容器（１００）の内側に入り込んだ形態となっていて、内容物を充填すると、図４に示すように、薄肉容器（２００）が融着されているフランジ部（８、８ａ）より反り返って、厚肉容器（１００）より外側に広がった状態となる。そして、内容物が抽出口（６）より吸引排出されると、ふたたび図３に示すように、薄肉容器（２００）が厚肉容器（１００）の内側に収納された形となる。
【００１６】
そこで、本発明のカートリッジ液体用容器（１）を図４に示すように、横倒しの状態で、すなわち細長いリブ（５２）が抽出口（６）より下側になり、下側となる薄肉容器（２００）の下側となる側面板（４２ａ）側が、上側となる側面板（４２ｂ）側より深さが浅いようにすることによって、カートリッジ液体用容器（１）の下側では厚肉容器（１００）と薄肉容器（２００）がほぼ同じ深さのようになるので吸引注出において内容物が著しく残留することがなくなるものである。
【００１７】
また、図５に示すように、内容物の吸引注出によって、口部（６ａ）近傍の薄肉容器（２００）も吸引されるが、口部（６ａ）周囲で、正面板（２０）側に略半円筒状のリブ（５０）を設けてあるので、この半円筒状のリブ（５０）に薄肉容器（２００）が当たり、口部（６ａ）の閉鎖を防止し、図７に示す半円筒状のリブ（５０）のない口部（６ａ）の半円状周辺部（６ｂ）から内容物が吸引排出される。このとき、口部（６ａ）周囲に向かって主に口部（６ａ）より下部に略放射状に設けた複数の細長いリブ（５２）によって、前記の口部（６ａ）の半円状周辺部（６ｂ）を薄肉容器（２００）で閉鎖することを防止するもので、内容物の吸引注出を容易にし残留量を極小とすることができる。なお、図７に示すように、上記細長いリブ（５２）の他に、上記半円筒状のリブ（５０）のない口部（６ａ）の半円状周辺部（６ｂ）に比較的短いリブ（５４）を放射状に設けることによって薄肉容器（２００）の吸引防止をより促進するものである。
【００１８】
これに対して、例えば図８に示すように、厚肉容器の側面板（４０）と平行に口部（６ａ）と同位置（底板（１０）の略中央）に細長いリブ（５２）を設けた場合、薄肉容器（２００）の吸引途中で、この細長いリブ（５２）に接し、薄肉容器（２００）が動き難くなり、結果的に内容物の残留量が大きくなる問題が発生する。
【００１９】
本発明のカートリッジ液体用容器（１）は、透明樹脂で作製することができるものであり、したがって、特に内容物が高粘性のエマルジョン、例えば印刷用インキ、マヨネーズ等の場合内容物の外観を観察することが可能で、内容物の変質によるトラブルを予め防止することができる。
【００２０】
本発明の厚肉容器（１００）としては、ポリエチレンの単層またはポリエチレン／変性ポリエチレン／ポリアマイド／変性ポリエチレン／ポリエチレンやポリエチレン／変性ポリエチレン／エチレン−ビニルアセテート鹸化物／変性ポリエチレン／ポリエチレン等の多層射出成形で作製されるもので、その厚さは、１ｍｍ〜１．２ｍｍである。
【００２１】
また、薄肉容器（２００）としては、ポリエチレンの単層またはポリエチレン／変性ポリエチレン／ポリアマイド／変性ポリエチレン／ポリエチレンやポリエチレン／変性ポリエチレン／ポリアマイド／変性ポリエチレン／エチレン−ビニルアセテート鹸化物／変性ポリエチレン／ポリエチレン等からなる単層および多層フィルムの真空成形や圧空成形等でによるもので、その厚さは、０．０５ｍｍ〜０．２５ｍｍという薄い袋状の容器である。
【００２２】
また、上記のように薄肉容器（２００）は薄い肉厚のため、これを保護する目的から必要に応じて、ポリプロピレン、エチレン−プロピレン共重合体、紙等からなる保護カバーを付加することができる。
【００２３】
なお、本発明の請求項１の発明において、厚肉容器（１００）の底板（１０）と正面板（２０）で形成する稜角部を切り欠き、切り欠き面（２０ａ）を設けるものとしたが、切り欠き面（２０ａ）を設けず正面板（２０）の同位置に抽出口（６）を同様の形態で設けたものでもよい。
【００２４】
【発明の効果】
本発明は以上の構成であるから、下記に示す如き効果がある。即ち、
液体自吸式機械に装着する、四角形状の底板と、該底板の周縁辺より上方に伸びる２枚の対向する側面板と、該側面板と隣合う正面板と後面板とで箱形状を成し、前記底板と正面板とで形成される陵角部を切り欠いた切り欠面を設け、該切り欠面の略中央部外側に内容物を吸引排出する抽出口を設けた厚肉容器と、該厚肉容器と略相似形状を成して該厚肉容器の内側に収納され、その上縁開口部のフランジ部を厚肉容器の上縁開口部のフランジ部と融着せしめた薄肉容器とでなるカートリッジ液体容器としたので、このカートリッジ液体用容器を装着する自吸式機械の設計に自由度が上げられ、特にカートリッジ液体用容器の収納や吸引の場所が小さくとれ、自吸式機械の吸引部の設計簡易化に寄与する効果がある。
【００２５】
また、上記厚肉容器の切り欠き面の内側で前記抽出口の開口している口部周縁辺に沿って上方に起立し、切り欠かれた開口部を有する略半円筒状のリブが該切り欠かれた開口部が前記後面板側に向いているように設けられ、該略半円筒状のリブより１方の側面板側にある切り欠き面内面上から底板内面上にかけて複数の細長いリブが設けられていることによって、上記の口部の半円状周辺部（略半円筒状のリブの無い部分）を薄肉容器で閉鎖することを防止するもので、内容物の吸引注出を安定で容易にし残留量を極小とすることができる。特に、従来の袋状の薄肉容器のみでできている液体容器に比らべ、格段に安定して吸引が可能となった。
【００２６】
また、本発明のカートリッジ液体用容器を横倒しの状態で、すなわち細長いリブが抽出口より下側になり、下側となる薄肉容器の側面板側が浅い深さとなるように、事務印刷機等自吸式機械に装着することによって、内容物の吸引注出においてカートリッジ液体用容器の下側では厚肉容器と薄肉容器が略同じ深さのような形態となり、内容物の残留が極少となる効果がある。

Two opposing side plates (40) extending upward from the edge, a front plate (20) adjacent to the side plates (40), and a rear plate (30) form a box shape, and the bottom plate (10 ) And the front plate (20) are provided with a notch surface (20a) with a cut-out corner portion cut out, and an extraction port (suction discharge) for the contents to be sucked and discharged outside the substantially central portion of the notch surface (20a) 6) and a thick container (100) provided with the thick container (100) and being accommodated inside the thick container (100), and being accommodated inside the thick container (100 ). A thin-walled container (200) in which the flange (8a) is fused with the flange (8) of the upper edge opening of the thick-walled container (100). In the cartridge liquid container, the notch surface (20a) of the thick-walled container (100) stands upward along the peripheral edge of the opening (6a) where the extraction port (6) is opened. A substantially semi-cylindrical rib (50) having an opened opening (50a) is provided so that the notched opening (50a) faces the rear plate (30), and the substantially semi-cylindrical Three elongated ribs (52) are provided from the inner surface of the notch surface (20A) to the inner surface of the bottom plate (10) on the side plate (40) side of the side plate (50). It is what .
[0013]
Further, in the invention of claim 2, as shown in FIG. 4, the height of the side plate (42a) of the thin container (200) corresponding to the side on which the elongated rib (52) is provided, that is, the side plate (42a). cartridge) depth side, characterized in that the side plates (42a) and a side plate (42b) of the height (thinner container (200 opposing thin container (200)) depth) good Ri small again This is a liquid container (1).
[0014]
Further, in the invention of claim 3 , as shown in FIG. 4, the cartridge liquid container (1) of the present invention is in a state of being laid down, that is, on the side where the elongated rib (52) is provided ( 100) one side plate (40) is characterized in that you have been attached to a liquid self-priming machine (not shown) so that the lower side.
[0015]
As described above, in the cartridge liquid container (1) of the present invention, as shown in FIG. 3, before the contents such as highly viscous ink are filled, the thin container (200) enters the thick container (100). When the contents are filled, as shown in FIG. 4, the thin-walled container (200) is warped from the flange portion (8, 8a) to which the thin-walled container (200) is fused, and is outside the thick-walled container (100). It becomes a state spread to. When the contents are sucked and discharged from the extraction port (6), the thin container (200) is housed inside the thick container (100) as shown in FIG.
[0016]
Therefore, as shown in FIG. 4, the cartridge liquid container (1) according to the present invention is in a laid-down state, that is, a thin-walled container (elongated rib (52) is located below the extraction port (6) and is located below). 200) the lower side plate (42a) side is shallower than the upper side plate (42b) side, so that the thicker container (100) is placed below the cartridge liquid container (1). ) And the thin-walled container (200) have substantially the same depth, so that the content does not remain significantly in the suction and extraction.
[0017]
Further, as shown in FIG. 5, the thin container (200) in the vicinity of the mouth portion (6a) is also sucked by sucking and dispensing the contents, but on the front plate (20) side around the mouth portion (6a). Since the semi-cylindrical rib (50) is provided, the thin-walled container (200) hits the semi-cylindrical rib (50) to prevent the mouth (6a) from being closed, and the semi-cylindrical shown in FIG. The contents are sucked and discharged from the semicircular peripheral part (6b) of the mouth part (6a) having no ribs (50). At this time, the semicircular peripheral portion (6a) of the mouth portion (6a) is mainly formed by a plurality of elongated ribs (52) provided radially downward from the mouth portion (6a) toward the periphery of the mouth portion (6a). 6b) is prevented from being closed with a thin container (200), and the content can be easily sucked out and the residual amount can be minimized. As shown in FIG. 7, in addition to the elongated rib (52), a relatively short rib (on the semicircular peripheral portion (6b) of the mouth portion (6a) without the semicylindrical rib (50) ( 54) is provided in a radial fashion to further prevent the thin-walled container (200) from being sucked.
[0018]
On the other hand, as shown in FIG. 8, for example, an elongated rib (52) is provided at the same position as the mouth (6a) (approximately the center of the bottom plate (10)) in parallel with the side plate (40) of the thick-walled container. In such a case, the thin container (200) comes into contact with the elongated rib (52) during the suction of the thin container (200), and the thin container (200) becomes difficult to move, resulting in a problem that the remaining amount of the contents becomes large.
[0019]
The cartridge liquid container (1) of the present invention can be made of a transparent resin, and therefore the appearance of the content is observed particularly when the content is a highly viscous emulsion, such as printing ink or mayonnaise. It is possible to prevent problems caused by alteration of contents.
[0020]

The thickness is 1 mm to 1.2 mm.
[0021]
The thin-walled container (200) may be a single layer of polyethylene or polyethylene / modified polyethylene / polyamide / modified polyethylene / polyethylene or polyethylene / modified polyethylene / polyamide / modified polyethylene / saponified ethylene-vinyl acetate / modified polyethylene / polyethylene. The thickness is a thin bag-shaped container having a thickness of 0.05 mm to 0.25 mm.
[0022]
Moreover, since the thin container (200) is thin as described above, a protective cover made of polypropylene, ethylene-propylene copolymer, paper, or the like can be added as necessary for the purpose of protecting the container. .
[0023]
In the invention of claim 1 of the present invention, the ridge corner formed by the bottom plate (10) and the front plate (20) of the thick container (100) is cut out to provide a cut-out surface (20a). The extraction port (6) may be provided in the same form at the same position of the front plate (20) without providing the notch surface (20a).

Since this invention is the above structure, there exist the following effects. That is,
A box shape is formed by a rectangular bottom plate mounted on a liquid self-priming machine, two opposing side plates extending upward from the peripheral edge of the bottom plate, and a front plate and a rear plate adjacent to the side plate. A thick-walled container provided with a cut-out surface formed by cutting out the corner formed by the bottom plate and the front plate, and provided with an extraction port for sucking and discharging the contents outside the substantially central portion of the cut-out surface; A thin-walled container having a shape substantially similar to that of the thick-walled container, housed inside the thick-walled container, and a flange portion of the upper edge opening thereof being fused with a flange portion of the upper edge opening of the thick-walled container since the cartridge liquid container made of a freedom in the design of self-priming the machine is raised to mount the cartridge liquid container, taken in particular locations of the housing and the suction of the cartridge liquid container is small, self-priming machine This contributes to simplification of the design of the suction part.
[0025]
In addition, a substantially semi-cylindrical rib standing upward along the peripheral edge of the mouth opening of the extraction port on the inner side of the notch surface of the thick container, and having a notched opening portion. A plurality of elongated ribs are provided so that the notched opening is directed to the rear plate side, and from the inner surface of the notch surface to the inner surface of the bottom plate on one side plate side from the substantially semi-cylindrical rib. By being provided, the semicircular peripheral part of the mouth (substantially semi-cylindrical part without ribs) is prevented from being closed with a thin-walled container. This makes it easy to minimize the residual amount. In particular, as compared with a liquid container made of only a conventional bag-like thin-walled container, suction can be made much more stable.
[0026]
In addition, the cartridge liquid container of the present invention is laid down on its side, i.e., the elongate rib is below the extraction port, and the side plate side of the thin container, which is the lower side, has a shallow depth. By attaching to the machine, the thick and thin containers are in the form of approximately the same depth below the cartridge liquid container in the suction and dispensing of the contents, and the effect of minimizing the residual contents is there.
