Description
本発明における実施例は中大型容量の密閉用容器に関する。 Embodiments of the present invention relate to a medium- and large-capacity airtight container.
密閉用容器は一般的に、例えば、ＬＣＤ工程に利用される感光材のような化学薬品を入れて包装するために使うことができる。このような化学薬品は高価であり、且つ人体に有害であるので、保管中又は、例えば、国内長距離運送や海外輸出等のような輸送では機密性を維持しなければならない。しかし、既存のこのような密閉用容器は、蓋の内側にパッドを付着させて、密封性を高めているが、プラスチック容器はその材質の関係で蓋とネック部の間の螺合による締結を非常に強くしても、一定時間、例えば、一日程度の時間が過ぎれば、蓋とネック部の間の締結強度が低下して、蓋のパッドの部分とネック部の端部との間で漏出が発生する可能性があり、延いては、環境問題と経済損失を引き起こす可能性がある。 Sealing containers can generally be used to contain and package chemicals such as photosensitive materials used in LCD processes, for example. Such chemicals are expensive and harmful to the human body, so confidentiality must be maintained during storage or transport such as domestic long distance transport or overseas exports. However, such existing sealing containers have a pad attached to the inside of the lid to improve the sealing performance. However, the plastic container is fastened by screwing between the lid and the neck portion due to its material. Even if it is very strong, after a certain period of time, for example, about a day, the fastening strength between the lid and the neck portion will decrease, and the gap between the lid pad portion and the neck end portion will decrease. Leakage can occur and, in turn, can cause environmental problems and economic losses.
また、ペットボトル等に使われている容器と比較して、化学薬品を入れる容器は、例えば容量が２０〜４０Ｌの中大型容量で、ネック部の内径は、例えば４〜５ｃｍ程度の大きさであるので、ネック部を完ぺきな円形に成形できていないという問題等がある。従って、一般的にＬＤＰＥ（Ｌｏｗ−ｄｅｎｓｉｔｙ ｐｏｌｙｅｔｈｙｌｅｎｅ）で製造するペットボトルに適用する密閉手段をそのまま中大型容量の密閉型容器の密閉に適用することには無理がある。 In addition, compared with containers used for PET bottles, containers for chemicals have a medium to large capacity of 20 to 40 L, for example, and the neck has an inner diameter of about 4 to 5 cm, for example. Therefore, there is a problem that the neck portion cannot be formed into a perfect circle. Therefore, it is impossible to apply the sealing means generally applied to PET bottles manufactured by LDPE (Low-Density Polyethylene) to the sealing of medium- and large-capacity sealed containers as they are.
本発明の実施例の目的は、蓋とネック部の間の密封性を向上させ、さらに、ネック部に締結する蓋の緩みを防止して、内容物の漏出を防止する中大型容量の密閉用容器を提供することである。 The purpose of the embodiment of the present invention is to improve the sealing performance between the lid and the neck portion, and further prevent loosening of the lid fastened to the neck portion and prevent leakage of the contents, for sealing Is to provide a container.

さらに、蓋（１０）は、スカート部（１１）の端部に形成される環型壁（１５）をさらに有することができる。この環型壁（１５）の内側面には、係止突起（１８）が一定の間隔を隔てて形成される。この係止突起（１８）は蓋（１０）がネック部（３１）に完全に締結した際、後述のネック部（３１）のラッチ歯（３３）に係止されることができ、蓋（１０）がネック部（３１）に締付された状態で固定する効果を得ることができる。従って、振動等の外力等によって蓋（１０）のネック部（３１）に対する締結が緩くなる現象を防止することができ、例えば、中大型密閉用容器（５０）の輸送で発生する可能性がある蓋（１０）による内容物の漏出を防止することができる。 Furthermore, the lid (10) can further have an annular wall (15) formed at the end of the skirt (11). Locking projections (18) are formed on the inner side surface of the annular wall (15) at regular intervals. When the lid (10) is completely fastened to the neck portion (31), the locking projection (18) can be locked to a latch tooth (33) of the neck portion (31) described later, and the lid (10) ) Can be secured in a state of being fastened to the neck portion (31). Accordingly, it is possible to prevent a phenomenon that the fastening of the lid (10) to the neck portion (31) is loosened due to an external force such as vibration, and may occur, for example, in transportation of the medium-sized and large-sized airtight container (50). Leakage of contents by the lid (10) can be prevented.
係止突起（１８）は、図２に示すように、一定の角度（α）、例えば約１０°の角度を隔てて配置されることができる。
また、係止突起（１８）は蓋（１０）の締付回転方向（図２では反時計方向）の前端に、一定の角度（β）、例えば３０°に傾斜された傾斜面（１８２）を形成し、蓋（１０）の締付回転方向の後端には係止面（１８１）が形成されることができる。該構成では、蓋（１０）がネック部（３１）に完全に締結された際、係止面（１８１）が後述のラッチ歯（３３）の係止面（１３５、図４を参照）に係止され、蓋（１０）の締結状態をそのまま維持することができる。
As shown in FIG. 2, the locking protrusions (18) can be arranged at a constant angle (α), for example, an angle of about 10 °.
Further, the locking projection (18) has an inclined surface (182) inclined at a certain angle (β), for example, 30 °, at the front end in the tightening rotation direction (counterclockwise in FIG. 2) of the lid (10). A locking surface (181) can be formed at the rear end of the lid (10) in the tightening rotation direction. In this configuration, when the lid (10) is completely fastened to the neck (31), the locking surface (181) is engaged with the locking surface (135, see FIG. 4) of the latch tooth (33) described later. It is stopped and the fastening state of the lid (10) can be maintained as it is.
図４は、本発明の１実施例における密閉用容器（５０）のボトル（３０）のネック部（３１）の部分平面図である。 FIG. 4 is a partial plan view of the neck portion (31) of the bottle (30) of the airtight container (50) in one embodiment of the present invention.
図３及び図４に示すように、ネック部（３１）の下端部には直接又は円弧形状のルート部（３６）を間に設けてラッチ歯（３３）が形成されることができる。ラッチ歯（３３）は、例えば、予め決定された角度（α）ほど、即ち、係止突起（１８）の離隔間隔ほど、離隔するように配置されることができる。且つ、ラッチ歯（３３）の形成範囲は、ボトル（３０）を、例えば、射出成形する際に容易に取り出すことができるように、ネック部（３１）に接する２本の平行接線の間のネック部（３１）の部分に形成することができる。 As shown in FIGS. 3 and 4, the lower end of the neck portion (31) can be provided with a latch tooth (33) by providing a root portion (36) directly or in an arc shape. The latch teeth (33) can be arranged to be separated by, for example, a predetermined angle (α), that is, by a separation interval of the locking projection (18). In addition, the formation range of the latch teeth (33) is such that the bottle (30) can be easily taken out when, for example, injection molding is performed, so that the neck between two parallel tangents contacting the neck portion (31). It can be formed in the part (31).
ラッチ歯（３３）は、蓋（１０）の締付回転方向（図４では時計回り方向）の前端には係止面（１３５）が形成され、蓋（１０）の締付回転方向の後端には、例えば、膨らんでいる傾斜曲面（１３４）が形成されることができる。該構成によれば、蓋（１０）を締付する際、対応する蓋（１０）の係止突起（１８）の傾斜面（１８２）がラッチ歯（３３）の傾斜曲面（１３４）を滑り超え、または相反して蓋（１０）の締付が緩くなる方向に回転させようとすると、蓋（１０）の係止突起（１８）の係止面（１８１）がラッチ歯（３３）の係止面（１３５）に係止されて、蓋（１０）の締付が緩くなる方向への回転を抑制することができる。 The latch tooth (33) has a locking surface (135) formed at the front end in the tightening rotation direction (clockwise direction in FIG. 4) of the lid (10), and the rear end in the tightening rotation direction of the lid (10). For example, a bulging inclined curved surface (134) can be formed. According to this configuration, when the lid (10) is tightened, the inclined surface (182) of the locking protrusion (18) of the corresponding lid (10) slips over the inclined curved surface (134) of the latch tooth (33). If, on the other hand, the lid (10) is rotated in a direction in which the tightening of the lid (10) is loosened, the locking surface (181) of the locking projection (18) of the lid (10) is locked to the latch teeth (33). The rotation in the direction in which the lid (10) is loosened can be suppressed by being locked to the surface (135).
図５は、本発明の１実施例における中大型密閉用容器（５０）の蓋（１０）とネック部（３１）が締結された状態で、ネック部（３１）の端部領域の部分拡大図である。 FIG. 5 is a partially enlarged view of the end region of the neck portion (31) in a state where the lid (10) and the neck portion (31) of the medium- and large-sized airtight container (50) in the embodiment of the present invention are fastened. It is.
図５に示すように、ネック部（３１）の端部の内側面には傾斜面（３４）が形成される。傾斜面（３４）はネック部（３１）の突出方向に対して外側に向けて一定の角度（γ）、例えば１０°〜３０°の角度を有することができる。さらに、蓋（１０）の環状突起部（１３）の溝（１６）に装着されるシールリング（１７）は、蓋（１０）がネック部（３１）に完全に締結されたとき、溝（１６）の外部に露出しているシールリング（１７）部分は、ネック部（３１）の傾斜面（３４）以外の内側面よりさらに外側に向けて突出することができ、傾斜面（３４）に押圧されて圧縮して密着する。該構成によれば、ネック部（３１）の端部には傾斜面（３４）を有するため、蓋（１０）はネック部（３１）に締結される際、ネック部（３１）によってシールリング（１７）に加えられるストレスが減少して、滑らかにネック部（３１）の内側に挿入されることができる。即ち、蓋（１０）をネック部（３１）に締結する際、蓋（１０）はネック部（３１）に沿ってボトル（３０）の内側に進入し、ネック部（３１）の傾斜面（３４）の直径がボトル（３０）の内側に進むほど減少するので、蓋（１０）の締付初期にはシールリング（１７）がネック部（３１）の傾斜面（３４）と線接触して滑らか、且つ大きい抵抗を有せずにネック部（３１）内に挿入して移動されることができ、ボトル（３０）の内側にさらに進むことで、傾斜面（３４）との線接触が面接触に転換されて、面接触領域が増加すると同時に、その接触圧力も更に増加し、シールリング（１７）の傾斜面（３４）に対する密封を最大にすることができる。また、中大型容器の場合、ネック部（３１）の直径が大きく、成形する際にネック部（３１）が完ぺきな円形に成形されなくても、ネック部（３１）の端部からボトル（３０）の内側に進むほどネック部（３１）の直径が減少するので、該ネック部（３１）の公差を克服できるようにシールリング（１７）のサイズを決定することができて、ネック部（３１）とシールリング（１７）の間の密封を更に確実に確保することができる。 As shown in FIG. 5, an inclined surface (34) is formed on the inner surface of the end of the neck portion (31). The inclined surface (34) may have a certain angle (γ) toward the outside with respect to the protruding direction of the neck portion (31), for example, an angle of 10 ° to 30 °. Further, the seal ring (17) mounted in the groove (16) of the annular protrusion (13) of the lid (10) is formed in the groove (16) when the lid (10) is completely fastened to the neck portion (31). The portion of the seal ring (17) exposed to the outside of the neck portion (31) can protrude further outward than the inner surface other than the inclined surface (34) of the neck portion (31), and is pressed against the inclined surface (34). Compressed and stuck. According to this configuration, since the end portion of the neck portion (31) has the inclined surface (34), when the lid (10) is fastened to the neck portion (31), the seal ring ( The stress applied to 17) is reduced, and it can be smoothly inserted into the neck portion (31). That is, when the lid (10) is fastened to the neck portion (31), the lid (10) enters the inside of the bottle (30) along the neck portion (31), and the inclined surface (34) of the neck portion (31). ) Decreases as the diameter of the bottle (30) increases, the seal ring (17) comes into line contact with the inclined surface (34) of the neck portion (31) at the initial stage of tightening the lid (10) and becomes smooth. In addition, it can be inserted and moved into the neck portion (31) without having a large resistance, and by proceeding further inside the bottle (30), the line contact with the inclined surface (34) is surface contact. At the same time as the surface contact area increases, the contact pressure also increases, and the seal against the inclined surface (34) of the seal ring (17) can be maximized. Further, in the case of a medium-sized container, the neck portion (31) has a large diameter, and even when the neck portion (31) is not formed into a perfect circle when forming, the bottle (30 ), The diameter of the neck portion (31) decreases, so the size of the seal ring (17) can be determined so that the tolerance of the neck portion (31) can be overcome, and the neck portion (31 ) And the seal ring (17) can be further ensured.
さらに、図５において、シールリング（１７）が挿入される溝（１６）の断面は環状突起部（１３）の延長方向と垂直になる方向に形成されるが、これに限定するものではなく、環状突起部（１３）の延長方向に対して傾斜されるように、例えば、傾斜面（３４）と垂直になるように形成されることもできる。 Furthermore, in FIG. 5, the cross section of the groove (16) into which the seal ring (17) is inserted is formed in a direction perpendicular to the extending direction of the annular protrusion (13), but this is not restrictive. For example, it may be formed so as to be perpendicular to the inclined surface (34) so as to be inclined with respect to the extending direction of the annular protrusion (13).
さらに、上述の説明において、溝（１６）は環状突起部（１３）の外側面に環状で形成されるが、これに限定するものではなく、溝（１６）を環状突起部（１３）において一定の間隔を隔てて複数個形成し、シールリング（１７）に突起（図示されていない）を設けて該溝（１６）に嵌めることで、シールリング（１７）を溝（１６）に設置することもできる Further, in the above description, the groove (16) is formed in an annular shape on the outer surface of the annular protrusion (13). However, the present invention is not limited to this, and the groove (16) is fixed in the annular protrusion (13). The seal ring (17) is installed in the groove (16) by providing a plurality of projections (not shown) on the seal ring (17) and fitting in the groove (16). Can also
さらに、図５において、シールリング（１７）の断面は円形であるが、例えば、溝（１６）の外部に突出する部分は図５と同じくし、溝（１６）の外部に突出していない部分を溝（１６）の断面形状に対応する断面形状にすることもできる。このような場合、シールリング（１７）の傾斜面（３４）に対する密着力をさらに少し高めることができる。 Furthermore, in FIG. 5, the cross section of the seal ring (17) is circular. For example, the portion protruding to the outside of the groove (16) is the same as FIG. 5, and the portion not protruding to the outside of the groove (16) is the same. A cross-sectional shape corresponding to the cross-sectional shape of the groove (16) can also be used. In such a case, the adhesion of the seal ring (17) to the inclined surface (34) can be further increased.
さらに、ネック部（３１）の端部の外側面には第２傾斜面（３４）が形成されることもできる。 Furthermore, a second inclined surface (34) may be formed on the outer surface of the end portion of the neck portion (31).
図７は、本発明の１実施例における中大型密閉用容器（５０）のネック部（３１）に締結される蓋（１０）を締付、又はその締付を解除するためのトルクレンチ（６０）の斜視図である。 FIG. 7 shows a torque wrench (60) for tightening or releasing the lid (10) fastened to the neck (31) of the medium- and large-sized hermetic container (50) in one embodiment of the present invention. FIG.
図７に示すように、トルクレンチ（６０）は蓋（１０）に外嵌するホルダー（６２）、及び該ホルダー（６２）に連結されているレバー（６１）を含む。ホルダー（６２）の内側面には蓋（１０）の外部突起（２１）を挿入することができる突起挿入溝（６３）が形成されており、作業員がレバー（６１）を回すことによって、ホルダー（６２）を回転させ、その回転力を蓋（１０）に伝達することができる。レバー（６１）の長さは蓋（１０）を締付又はその締付を解除することに必要なトルクを考慮して決定することができる。 As shown in FIG. 7, the torque wrench (60) includes a holder (62) fitted on the lid (10), and a lever (61) connected to the holder (62). A protrusion insertion groove (63) into which the external protrusion (21) of the lid (10) can be inserted is formed on the inner side surface of the holder (62), and when the operator turns the lever (61), the holder (62) can be rotated and the rotational force transmitted to the lid (10). The length of the lever (61) can be determined in consideration of the torque required to tighten or release the lid (10).
蓋（１０）が締付され状態で、係止突起（１８）の係止面（１８１）がラッチ歯（３３）の係止面（１３５）に係止されて、蓋（１０）の回転が抑制されているので、蓋（１０）の締付を解除するとき、蓋（１０）の係止突起（１８）及びラッチ歯（３３）の中の少なくとも任意の一つが破損される恐れがある。 With the lid (10) being tightened, the locking surface (181) of the locking projection (18) is locked to the locking surface (135) of the latch tooth (33), and the rotation of the lid (10) is performed. Since it is restrained, when releasing the tightening of the lid (10), at least any one of the locking projection (18) and the latch tooth (33) of the lid (10) may be damaged.
さらに、上述の説明において、シールリング（１７）は蓋（１０）の環状突起部（１３）に配置されるが、シールリング（１７）はネック部（３１）の傾斜面（３４）に形成された溝（図示されていない）に設置されることもできる。この場合、蓋（１０）の環状突起部（１３）の外側面には溝（１６）の代わりにネック部（３１）の傾斜面（３４）に対応する傾斜面、又は膨らんだ部分等を形成することもできる。 Further, in the above description, the seal ring (17) is disposed on the annular protrusion (13) of the lid (10), but the seal ring (17) is formed on the inclined surface (34) of the neck portion (31). It can also be installed in a groove (not shown). In this case, an inclined surface corresponding to the inclined surface (34) of the neck portion (31) or an inflated portion is formed on the outer surface of the annular protrusion (13) of the lid (10) instead of the groove (16). You can also
上述のように構成された本発明の１実施例における中大型密閉用容器（５０）は、ネック部（３１）の端部の内側面に傾斜面（３４）が形成され、蓋（１０）の環状突起部（１３）の外側面の溝（１６）に装着されるシールリング（１７）によって、蓋（１０）がネック部（３１）に締結される際、シールリング（１７）はネック部（３１）の内側面から少ないストレスを受け、滑らかにネック部（３１）の内側面に沿って挿入されることができる。蓋（１０）がネック部（３１）に完全に締結した際、溝（１６）の外側に向けて突出したシールリング（１７）の部分が傾斜面（３４）に面接触して圧着されるので、ネック部（３１）の内側面とシールリング（１７）の間を通る内容物の漏出を防止することができる。特に、化学薬品を入れる中大型容器の場合、ネック部（３１）の直径が大きくて完ぺきな円形に形成されることが困難であるが、このような場合でも、ネック部（３１）の内側の傾斜面（３４）にシールリング（１７）を滑らかにネック部（３１）の内側に挿入しながらも、傾斜面（３４）に強く圧着できるようにサイズを決定することができるので、ボトル（３０）内の内容物の漏出を確実に防止することができる。同時に、蓋（１０）がネック部（３１）に完全に締結した際、蓋（１０）の係止突起（１８）とネック部（３１）のラッチ歯（３３）の相互作用によって蓋（１０）の締付が緩くなることを防止し、シールリング（１７）とネック部（３１）の内側面の間の密封を蓋（１０）の開放時まで維持されることができる。従って、中大型密閉用容器（５０）を長期保管しても、又は、輸送中に発生する振動による漏出の発生も防止することができる。 The middle- and large-sized container (50) according to the embodiment of the present invention configured as described above has an inclined surface (34) formed on the inner surface of the end portion of the neck portion (31), and the lid (10). When the lid (10) is fastened to the neck portion (31) by the seal ring (17) attached to the groove (16) on the outer surface of the annular projection (13), the seal ring (17) 31) receives less stress from the inner surface of the neck portion 31 and can be smoothly inserted along the inner surface of the neck portion (31). When the lid (10) is completely fastened to the neck portion (31), the portion of the seal ring (17) protruding toward the outside of the groove (16) comes into surface contact with the inclined surface (34) and is crimped. The leakage of the contents passing between the inner surface of the neck portion (31) and the seal ring (17) can be prevented. In particular, in the case of a medium-sized container containing chemicals, it is difficult to form a perfect circle with a large diameter of the neck (31). Even in such a case, the inside of the neck (31) Since the seal ring (17) can be smoothly inserted into the inside of the neck portion (31) on the inclined surface (34), the size can be determined so that it can be strongly pressed against the inclined surface (34). ) Can be surely prevented from leaking out the contents. At the same time, when the lid (10) is completely fastened to the neck portion (31), the lid (10) is caused by the interaction between the locking projection (18) of the lid (10) and the latch teeth (33) of the neck portion (31). And the sealing between the seal ring (17) and the inner surface of the neck portion (31) can be maintained until the lid (10) is opened. Therefore, even if the medium-sized and large-sized airtight container (50) is stored for a long period of time, it is possible to prevent the occurrence of leakage due to vibration generated during transportation.
