Description

本開示は、蓋体に関する。 This disclosure relates to a lid.

この種の蓋体として、蓋体の一部の開封バンド部を切除すると容器本体から取り外し可能となるものが知られている（例えば、特許文献１参照）。 A known lid of this type can be removed from the container body by cutting off an opening band portion of the lid (see, for example, Patent Document 1).

特開平９－１１００５８号公報（図１）JP-A-9-110058 (FIG. 1)

上述した蓋体は、蓋体同士を安定して段積みできないという問題があった。これに対し、安定して段積み可能な蓋体の開発が求められている。 The above-mentioned lids have the problem that they cannot be stably stacked on top of each other. In response to this, there is a demand for the development of lids that can be stably stacked.

上記目的を達成するためになされた請求項１の発明は、容器本体の上端部の外側に嵌合する嵌合壁を上下に分割した下側部分が開封バンド部となっていて、前記開封バンド部を切除すると容器本体から取り外し可能となる蓋体において、蓋体の上面に、設けられた上面嵌合部を備え、前記開封バンド部が切除される前の切除前状態の蓋体を上方に段積みした場合には、前記嵌合壁のうち前記開封バンド部の内側に下段側の蓋体の前記上面嵌合部が受容され、蓋体同士の横ずれが規制され、前記開封バンド部が切除された後の切除後状態の蓋体を上方に段積みした場合には、前記嵌合壁のうち前記開封バンド部が切除されてなる残留部の内側に下段側の蓋体の前記上面嵌合部が受容され、蓋体同士の横ずれが規制され、前記開封バンド部と、前記残留部とが同一面上に位置し、蓋体の上面は、前記嵌合壁の上端から内側に延びた外縁壁部と、前記外縁壁部より内側を下方に陥没させてなる内側陥没部と、を備え、前記上面嵌合部は、前記外縁壁部より上方に突出しかつ前記外縁壁部と前記内側陥没部の外縁部とに跨って配され、前記上面嵌合部の外側端部は、前記嵌合壁の外側面の延長線上よりも内側に位置し、蓋体同士を段積みすると、上段側の蓋体の前記嵌合壁は、前記切除前状態か前記切除後状態かに拘わらず、下段側の蓋体の前記上面のうち前記上面嵌合部よりも外側に当接する蓋体である。 The invention of claim 1 made to achieve the above object provides a lid body in which a fitting wall that fits onto the outside of the upper end of a container body is divided into upper and lower parts, the lower part being a tear-open band part, and which can be removed from the container body by cutting off the tear-open band part, the lid body being provided with an upper surface fitting part on the upper surface thereof, and when lid bodies in a pre-removal state before the tear-open band part is cut off are stacked one above the other, the upper surface fitting part of the lid body on the lower side is received on the inside of the tear-open band part of the fitting wall, thereby restricting lateral displacement between the lid bodies, and when lid bodies in a post-removal state after the tear-open band part is cut off are stacked one above the other, the lower side fitting part is received on the inside of the remaining part of the fitting wall where the tear-open band part has been cut off, The top surface fitting portion of the lid body is received, lateral shifting between the lid bodies is restricted, the opening band portion and the remaining portion are located on the same plane , the top surface of the lid body comprises an outer edge wall portion extending inward from the upper end of the fitting wall, and an inner recessed portion formed by recessing the inside of the outer edge wall portion downward, the top surface fitting portion protrudes upward from the outer edge wall portion and is arranged across the outer edge wall portion and the outer edge of the inner recessed portion, the outer end portion of the top surface fitting portion is located inside the extension line of the outer surface of the fitting wall, and when the lid bodies are stacked on top of each other, the fitting wall of the upper lid body is a lid body that abuts the top surface of the lower lid body outside the top surface fitting portion regardless of whether it is in the pre-removal state or the post-removal state .

請求項２の発明は、前記上面嵌合部は、蓋体の上面のうち外周縁部の複数個所から上方に突出しかつ、内外方向に延びた複数の平リブから構成されている請求項１に記載の蓋体である。 The invention of claim 2 is a lid body described in claim 1 , wherein the upper surface fitting portion is composed of a plurality of flat ribs protruding upward from multiple points on the outer peripheral edge of the upper surface of the lid body and extending inward and outward.

請求項３の発明は、前記切除後状態の蓋体を上方に段積みすると、下段側の蓋体の前記上面嵌合部の上端面に上段側の蓋体の前記内側陥没部の底面が当接する請求項１又は２に記載の蓋体である。 The invention of claim 3 is a lid body as described in claim 1 or 2, in which, when the lid bodies in the post -removal state are stacked one on top of the other , the bottom surface of the inner recessed portion of the upper lid body abuts against the upper end surface of the upper surface fitting portion of the lower lid body.

請求項１の蓋体によれば、開封バンド部が切除される前の切除前状態か切除された後の切除後状態かに拘わらず、蓋体同士を段積みしたときに上下の蓋体同士が嵌合するので、蓋体同士の段積みを安定させることができる。 According to the lid of claim 1, regardless of whether the opening band portion is in a pre-removal state before being cut or in a post-removal state after being cut, the upper and lower lids fit together when stacked on top of each other, so the stacking of the lids can be stabilized.

また、切除後状態の蓋体同士を積み重ねたときの高さが、切除前状態の蓋体同士を積み重ねたときの高さよりも小さくなるので、蓋体同士を積み重ねたときの嵩を減らすことができる。また、上面嵌合部の外側端部が、嵌合壁の外側面の延長線上よりも内側に位置し、上段側の蓋体の嵌合壁が、下段側の蓋体の上面のうち前記上面嵌合部よりも外側に当接するので、段積みされた複数の蓋体群全体の外側面の凹凸を抑えることができる。 In addition, since the height of the lids in the post-removal state when stacked together is smaller than the height of the lids in the pre-removal state when stacked together, the bulk of the lids can be reduced. Also, since the outer end of the upper surface fitting portion is located inside the extension line of the outer surface of the fitting wall, and the fitting wall of the upper lid body abuts on the upper surface of the lower lid body outside the upper surface fitting portion, it is possible to suppress unevenness on the outer surface of the entire group of stacked lid bodies.

上面嵌合部は、蓋体の上面に外縁に沿って延びた環状突部であってもよいし、請求項２のように、蓋体の上面のうち外周縁部の複数個所に配された平リブであってもよい。 The upper surface fitting portion may be an annular protrusion extending along the outer edge of the upper surface of the lid, or as in claim 2 , it may be flat ribs arranged at multiple locations on the outer circumferential edge of the upper surface of the lid.

請求項３の蓋体によれば、上段側の蓋体の内側陥没部の底面が下段側の蓋体の上面嵌合部の上端面に当接して支持されるので、段積みが安定する。 According to the lid body of claim 3 , the bottom surface of the inner recess of the upper lid body abuts against and is supported by the upper end surface of the upper surface fitting portion of the lower lid body, so that the stacking is stable.

図１には、容器本体１１と、容器本体１１の上面開口１１Ｋ（図２参照）を密閉する蓋体２０と、からなる容器１０が示されている。容器本体１１及び蓋体２０は、何れも例えば樹脂の射出品である。 Figure 1 shows a container 10 consisting of a container body 11 and a lid body 20 that seals the top opening 11K (see Figure 2) of the container body 11. Both the container body 11 and the lid body 20 are, for example, injected resin.

容器本体１１は、平面視正方形状の底壁１２（図２参照）と、下方へ向かうにつれて僅かに狭まる側壁１３と、を有している。図２に示すように、底壁１２と側壁１３とは丸みを帯びて連絡している。また、底壁１２の下面には、外周縁寄り位置から下方へ突出した環状の突条１２Ｂが形成されている。 The container body 11 has a bottom wall 12 (see FIG. 2) that is square in plan view, and a side wall 13 that narrows slightly downward. As shown in FIG. 2, the bottom wall 12 and the side wall 13 are connected by a rounded edge. In addition, the lower surface of the bottom wall 12 is formed with an annular protrusion 12B that protrudes downward from a position near the outer periphery.

同図に示すように、容器本体１１の側壁１３の上端は、その下方部よりも僅かに肉厚になった肉厚部１４となっている。肉厚部１４は側壁１３の外方に突出していて、その下面１４Ａは水平に延びている。また、容器本体１１の側壁１３の外側面の上端部には、肉厚部１４の下方に、上下に並んで配された第１～第３の突条１５～１７が、側壁１３の全周に亘って突出形成されている。第１の突条１５と第２の突条１６との先端の断面は半円状になっているのに対し、第３の突条１７の先端の断面は、下面が水平になった扇形になっている。また、第２の突条１６は第１の突条１５よりも僅かに外方に突出していて、第３の突条１７は第２の突条１６よりも僅かに外方に突出している。 As shown in the figure, the upper end of the side wall 13 of the container body 11 is a thick portion 14 that is slightly thicker than the lower portion. The thick portion 14 protrudes outward from the side wall 13, and its lower surface 14A extends horizontally. In addition, at the upper end of the outer surface of the side wall 13 of the container body 11, first to third protrusions 15 to 17 are arranged vertically below the thick portion 14 and protrude around the entire circumference of the side wall 13. The cross sections of the tips of the first protrusion 15 and the second protrusion 16 are semicircular, while the cross section of the tip of the third protrusion 17 is fan-shaped with a horizontal lower surface. In addition, the second protrusion 16 protrudes outward slightly more than the first protrusion 15, and the third protrusion 17 protrudes outward slightly more than the second protrusion 16.

容器本体１１の側壁１３における上端部のうち第３の突条１７の下方には、外面から水平に突出したのち下方へ折り返した折り返しリブ１８が形成されている。折り返しリブ１８は、第３の突条１７よりも板厚１枚分程外方に突出している。また、折り返しリブ１８の上下方向に延びた折り返し壁１８Ａは、下方へいくにつれ僅かに外方へ広がるように傾斜している。図１に示すように、容器本体１１の折り返しリブ１８のうち対角線上の２角には、取っ手１９を取り付けるための突起１８Ｂが形成されている。また、側壁１３のコーナー部の外面には、折り返しリブ１８との間を連絡しかつ折り返しリブ１８よりも下方へ延びる補強リブ１３Ｌが設けられている。 Below the third protrusion 17 at the upper end of the side wall 13 of the container body 11, a folded rib 18 is formed, which protrudes horizontally from the outer surface and then folds downward. The folded rib 18 protrudes outward from the third protrusion 17 by about one plate thickness. In addition, the folded wall 18A extending in the vertical direction of the folded rib 18 is inclined so as to widen slightly outward as it goes downward. As shown in FIG. 1, protrusions 18B for attaching handles 19 are formed at two diagonal corners of the folded rib 18 of the container body 11. In addition, a reinforcing rib 13L is provided on the outer surface of the corner portion of the side wall 13, which connects with the folded rib 18 and extends downward beyond the folded rib 18.

図１に示すように、蓋体２０は、容器本体１１と同様、平面形状が正方形状になっていて、天井壁３０の外縁から容器本体１１と嵌合するための嵌合壁２１（特許請求の範囲中の「第２嵌合部」に相当する）が下方へ延びている。天井壁３０における外縁寄り位置より内側は下方へ陥没した内側陥没部３１となっていて、内側陥没部３１の側壁３１Ａと、嵌合壁２１との間に容器本体１１における側壁１３の上端部が嵌まり、蓋体２０が容器本体１１に嵌合する（図２参照）。また、天井壁３０には、その外周縁部の複数位置に、内側陥没部３１と、その外側の外縁壁部３２とに跨って形成された平リブ３３が設けられていて、容器１０同士を段積みすると、下段の容器１０における内側陥没部３１のうち平リブ３３群の内側に、上段の容器１０が嵌合する（図３及び図４参照）。なお、これら平リブ３３群から、特許請求の範囲中の「第１嵌合部」が構成されている。 1, the lid 20 has a square planar shape like the container body 11, and a fitting wall 21 (corresponding to the "second fitting portion" in the claims) for fitting with the container body 11 extends downward from the outer edge of the ceiling wall 30. The inner side of the outer edge of the ceiling wall 30 is an inner recess 31 that is recessed downward, and the upper end of the side wall 13 of the container body 11 fits between the side wall 31A of the inner recess 31 and the fitting wall 21, so that the lid 20 fits with the container body 11 (see FIG. 2). In addition, the ceiling wall 30 has flat ribs 33 formed across the inner recess 31 and the outer peripheral wall 32 at multiple positions on its outer periphery, so that when the containers 10 are stacked on top of each other, the upper container 10 fits inside the group of flat ribs 33 in the inner recess 31 of the lower container 10 (see FIGS. 3 and 4). These flat ribs 33 form the "first fitting portion" in the claims.

図２に示すように、嵌合壁２１は、容器本体１１の折り返しリブ１８の上面まで延びている。また、嵌合壁２１は、下方へいくにつれ僅かに外方へ広がるように傾斜していて、その傾きは、容器本体１１の折り返しリブ１８の折り返し壁１８Ａの傾きと略同一である。これにより、蓋体２０が容器本体１１に嵌合した状態では、嵌合壁２１と容器本体１１の折り返しリブ１８との外側面が連続しかつ略面一となる。 As shown in FIG. 2, the fitting wall 21 extends up to the upper surface of the folded rib 18 of the container body 11. The fitting wall 21 is also inclined so that it widens slightly outward as it extends downward, and the inclination is approximately the same as the inclination of the folded wall 18A of the folded rib 18 of the container body 11. As a result, when the lid 20 is fitted to the container body 11, the outer surfaces of the fitting wall 21 and the folded rib 18 of the container body 11 are continuous and approximately flush with each other.

図２及び図５に示すように、嵌合壁２１の内面の上端部には、内側に突出した突条２２が形成されている。突条２２は、平面形状の正方形の各辺のうち両端部を除いた部分に水平に延びて設けられていて、容器本体１１の肉厚部１４の下面１４Ａと凹凸係合する。また、図２に示すように、嵌合壁２１と内側陥没部３１の側壁３１Ａとの間のうち上端部には、容器本体１１との密閉性を高めるパッキン４０が取り付けられている。 As shown in Figures 2 and 5, a protrusion 22 that protrudes inward is formed at the upper end of the inner surface of the engagement wall 21. The protrusion 22 extends horizontally on each side of the square planar shape except for both ends, and engages with the underside 14A of the thick part 14 of the container body 11 in a concave-convex manner. Also, as shown in Figure 2, a gasket 40 that improves the airtightness with the container body 11 is attached to the upper end between the engagement wall 21 and the side wall 31A of the inner recess 31.

図２及び図６に示すように、嵌合壁２１の外面における上下方向の中央部には、内面寄り位置まで延びたＶ溝２３が形成され、Ｖ溝２３の底部が薄肉部２４になっている。図６～図８に示すように、Ｖ溝２３のうち蓋体２０の平面形状である正方形の一辺の中央部に配された部分は、内外方向に貫通した第１切り込み２３Ｋになっていて、第１切り込み２３Ｋの左端（図７中の左端）の左隣（図７中の左隣）には、嵌合壁２１におけるＶ溝２３より下方部分の上部を切り欠いてなる第１切り欠き２６Ａが形成されている。また、嵌合壁２１には、第１切り欠き２６Ａの下端から図中における右方へ延びた溝２５と、溝２５の右隣に配され、嵌合壁２１のうち溝２５より下方部分を切り欠いてなる第２切り欠き２６Ｂと、が形成されている。溝２５のうち第１切り欠き２６Ａに隣接する部分は、内外方向に貫通した第２切り込み２５Ｋとなっていて、嵌合壁２１のうち第１切り込み２３Ｋと第２切り込み２５Ｋとに挟まれた部分はつまみ片２８となっている。 2 and 6, a V-groove 23 is formed in the vertical center of the outer surface of the fitting wall 21, extending to a position close to the inner surface, and the bottom of the V-groove 23 is a thin-walled portion 24. As shown in Figs. 6 to 8, the portion of the V-groove 23 arranged in the center of one side of the square planar shape of the lid body 20 is a first notch 23K penetrating in the inward and outward directions, and a first notch 26A is formed to the left (to the left in Fig. 7) of the left end (to the left in Fig. 7) of the first notch 23K by cutting out the upper part of the part below the V-groove 23 in the fitting wall 21. In addition, the fitting wall 21 is formed with a groove 25 extending to the right in the figure from the bottom end of the first notch 26A, and a second notch 26B arranged to the right of the groove 25 and formed by cutting out the part of the fitting wall 21 below the groove 25. The portion of the groove 25 adjacent to the first notch 26A is a second notch 25K that penetrates in the inward and outward direction, and the portion of the fitting wall 21 that is sandwiched between the first notch 23K and the second notch 25K is a knob piece 28.

そして、つまみ片２８を持ち、右方へ引っ張ると、溝２５の底部が破断したのち、薄肉部２４が破断して、嵌合壁２１のうち薄肉部２４より下側の開封バンド部２１Ｘが上側の嵌合壁本体２１Ｙ（特許請求の範囲中の「残留部」に相当する）に対して引き裂かれて切除される（図９及び図１０参照）。以降、適宜、開封バンド部２１Ｘが切除される前の蓋体２０の状態を切除前状態といい、開封バンド部２１Ｘが切除された後の蓋体２０の状態を切除後状態という。 When the gripping piece 28 is grasped and pulled to the right, the bottom of the groove 25 breaks, the thin-walled portion 24 breaks, and the opening band portion 21X below the thin-walled portion 24 of the fitting wall 21 is torn away from the upper fitting wall main body 21Y (corresponding to the "remaining portion" in the claims) and cut off (see Figures 9 and 10). Hereinafter, the state of the lid body 20 before the opening band portion 21X is cut off will be referred to as the "pre-cut state," and the state of the lid body 20 after the opening band portion 21X is cut off will be referred to as the "post-cut state."

図２に示すように、開封バンド部２１Ｘの板厚は嵌合壁本体２１Ｙの板厚よりも小さくなっていて、嵌合壁本体２１Ｙの内面の下端部は薄肉部２４の内面へ傾斜して連絡している。また、開封バンド部２１Ｘの下端には、内側に突出した係合突条２７が設けられている。係合突条２７では、最も内側に位置する頂部２７Ａが係合突条２７の幅のうち上端寄り位置に配されていて、係合突条２７の上側側面が、容器本体１１の第３の突条１７の下面に対向する。これにより、切除前状態の蓋体２０が容器本体１１に嵌合した状態では、蓋体２０の係合突条２７と容器本体１１の第３の突条１７とが係合する。この係合突条２７と第３の突条１７との対向幅は、突条２２と肉厚部１４の下面１４Ａとの対向幅よりも大きくなっている。 2, the thickness of the opening band portion 21X is smaller than that of the fitting wall body 21Y, and the lower end of the inner surface of the fitting wall body 21Y is inclined to connect to the inner surface of the thin-walled portion 24. In addition, an engagement ridge 27 protruding inward is provided at the lower end of the opening band portion 21X. The innermost apex 27A of the engagement ridge 27 is located near the upper end of the width of the engagement ridge 27, and the upper side surface of the engagement ridge 27 faces the lower surface of the third ridge 17 of the container body 11. As a result, when the lid body 20 in the pre-removal state is fitted to the container body 11, the engagement ridge 27 of the lid body 20 and the third ridge 17 of the container body 11 engage with each other. The opposing width of the engagement ridge 27 and the third ridge 17 is larger than the opposing width of the ridge 22 and the lower surface 14A of the thick-walled portion 14.

ここで、上述したように、蓋体２０の天井壁３０には、その外周縁部の複数位置に、平リブ３３が設けられている。図２に示すように、平リブ３３は、天井壁３０の外縁壁部３２よりも上方に位置し、水平に延びる上端面３３Ａと、上端面３３Ａの内側端部から内側陥没部３１の底部３１Ｂとの間を連絡する内側端面３３Ｂと、上端面３３Ａの外側端部と外縁壁部３２の上面との間を連絡する外側端面３３Ｃとを有している。つまり、平リブ３３は、天井壁３０の外縁壁部３２、内側陥没部３１の側壁３１Ａ及び内側陥没部３１の底部３１Ｂにわたり連続して設けられている。ここで、外縁壁部３２のうち嵌合壁２１との連絡部分の上面は、下方へ湾曲した曲面３２Ａとなっていて、平リブ３３の外側端面３３Ｃは、この曲面３２Ａの内側端部に連絡している。また、外側端面３３Ｃは、下方へ向かうにつれ外方に進むように傾斜していて、鉛直方向に対する角度が嵌合壁２１よりも大きくなっている。これにより、平リブ３３の外側端面３３Ｃは、嵌合壁２１の外側面の延長線上よりも内側に位置している。 As described above, the ceiling wall 30 of the lid 20 has flat ribs 33 at multiple positions on its outer periphery. As shown in FIG. 2, the flat rib 33 is located above the outer edge wall 32 of the ceiling wall 30 and has a horizontally extending upper end surface 33A, an inner end surface 33B connecting the inner end of the upper end surface 33A to the bottom 31B of the inner recess 31, and an outer end surface 33C connecting the outer end of the upper end surface 33A to the upper surface of the outer edge wall 32. In other words, the flat rib 33 is provided continuously over the outer edge wall 32 of the ceiling wall 30, the side wall 31A of the inner recess 31, and the bottom 31B of the inner recess 31. Here, the upper surface of the outer edge wall 32 that connects with the fitting wall 21 is a curved surface 32A that curves downward, and the outer end surface 33C of the flat rib 33 connects to the inner end of this curved surface 32A. Additionally, the outer end surface 33C is inclined downward and outward, with an angle greater than that of the fitting wall 21 relative to the vertical direction. As a result, the outer end surface 33C of the flat rib 33 is located inside the extension of the outer surface of the fitting wall 21.

そして、図１１に示すように、上に切除前状態の蓋体２０が重ねられたときには、上側の蓋体２０の嵌合壁２１の開封バンド部２１Ｘが下側の蓋体２０の外縁壁部３２の上面（曲面３２Ａ）に当接し、かつ、下側の蓋体２０の平リブ３３群の外側に上側の蓋体２０の開封バンド部２１Ｘが嵌合する。一方、図１２～１４に示すように、上に切除後状態の蓋体２０が重ねられたときには、上側の蓋体２０の嵌合壁２１の嵌合壁本体２１Ｙが下側の蓋体２０の外縁壁部３２の上面（曲面３２Ａ）に当接しかつ、下側の蓋体２０の平リブ３３群の外側に上側の蓋体２０の嵌合壁本体２１Ｙが嵌合する。また、上に切除後状態の蓋体２０が重ねられたときには、下側の蓋体２０の平リブ３３上端面３３Ａに上側の蓋体２０の内側陥没部３１の下面（底部３１Ｂの下面）が当接する。 As shown in Fig. 11, when the lid body 20 in the pre-removal state is placed on top, the opening band portion 21X of the fitting wall 21 of the upper lid body 20 abuts against the upper surface (curved surface 32A) of the outer edge wall portion 32 of the lower lid body 20, and the opening band portion 21X of the upper lid body 20 fits on the outside of the group of flat ribs 33 of the lower lid body 20. On the other hand, as shown in Figs. 12 to 14, when the lid body 20 in the post-removal state is placed on top, the fitting wall main body 21Y of the fitting wall 21 of the upper lid body 20 abuts against the upper surface (curved surface 32A) of the outer edge wall portion 32 of the lower lid body 20, and the fitting wall main body 21Y of the upper lid body 20 fits on the outside of the group of flat ribs 33 of the lower lid body 20. In addition, when the lid body 20 in the post-removal state is placed on top, the lower surface of the inner recess 31 (the lower surface of the bottom 31B) of the upper lid body 20 abuts against the upper end surface 33A of the flat rib 33 of the lower lid body 20.

本実施形態の容器１０の構成に関する説明は以上である。次に、この容器１０の作用効果について説明する。この容器１０は、例えば、染料や調味料等の液体や食品を収容して運搬、販売するために使用される。そのためには、収容物が収容された容器本体１１の上端部を蓋体２０の嵌合壁２１と内側陥没部３１の側壁３１Ａとで挟むようにして蓋体２０を押し込む。すると、蓋体２０の突条２２が容器本体１１の肉厚部１４に係合すると共に、蓋体２０の係合突条２７が容器本体１１の第３の突条１７に係合し、蓋体２０が容器本体１１に嵌合固定（所謂、嵌め殺し）される（図１及び図２参照）。このとき、蓋体２０の嵌合壁２１の下端部が容器本体１１の折り返しリブ１８の上面に当接し、その外面が略面一になるので、開封バンド部２１Ｘの裏側に意図せず何かが引っ掛かり、蓋体２０が外れてしまうことが防がれる。 This concludes the description of the configuration of the container 10 of this embodiment. Next, the effects of the container 10 will be described. The container 10 is used to store, transport, and sell liquids and foods such as dyes and seasonings. To do so, the lid 20 is pressed into the container body 11, in which the contents are stored, so that the upper end of the container body 11 is sandwiched between the mating wall 21 of the lid 20 and the side wall 31A of the inner recess 31. Then, the protrusion 22 of the lid 20 engages with the thick portion 14 of the container body 11, and the mating protrusion 27 of the lid 20 engages with the third protrusion 17 of the container body 11, and the lid 20 is fixed to the container body 11 (so-called fixed fit) (see Figures 1 and 2). At this time, the lower end of the fitting wall 21 of the lid 20 abuts against the upper surface of the folded rib 18 of the container body 11, and the outer surfaces become approximately flush, preventing something from accidentally getting caught on the back side of the opening band portion 21X and causing the lid 20 to come off.

容器１０を開封するときは、つまみ片２８を引っ張り、開封バンド部２１Ｘを引き裂き切除することで、係合突条２７と第３の突条１７との係合が解除され、蓋体２０を外すことができる。また、蓋体２０の突条２２と容器本体１１の肉厚部１４とが係合するので、開封バンド部２１Ｘが切除された後、つまり、容器１０の開封後でも、蓋体２０が容器本体１１に弱めに係止され、振動などにより蓋体２０が外れることが防止される。なお、突条２２と肉厚部１４の下面１４Ａとの対向幅は、係合突条２７と第３の突条１７との対向幅よりも小さくなっているので、係止機能を有しながらも、取り外しを容易にすることができる。 When opening the container 10, the gripping piece 28 is pulled and the opening band portion 21X is torn off, which disengages the engaging ridge 27 from the third ridge 17, allowing the lid 20 to be removed. In addition, the ridge 22 of the lid 20 engages with the thick portion 14 of the container body 11, so that even after the opening band portion 21X is cut off, that is, after the container 10 is opened, the lid 20 is weakly locked to the container body 11, preventing the lid 20 from coming off due to vibration or the like. The opposing width between the ridge 22 and the underside 14A of the thick portion 14 is smaller than the opposing width between the engaging ridge 27 and the third ridge 17, so that the lid can be easily removed while still retaining its locking function.

ところで、従来のこの種の容器では、蓋体同士が嵌合するようにはなっておらず、蓋体同士を段積みできない、もしくは、段積みしても不安定になっていた。この容器では、取り付け前の蓋体を保管しておく時に蓋体がばらけてしまったり、蓋体を容器本体に取り付ける作業の時に、蓋体をバラバラに置かれている中から取り出す必要があり、手間取ることがあった。 However, in conventional containers of this type, the lids are not designed to fit together, making it impossible to stack them on top of each other, or even if they were stacked, they were unstable. With this type of container, the lids tend to come apart when stored before being attached, and when attaching the lids to the container body, it is necessary to remove the lids from among the scattered lids, which can be time-consuming.

これに対して、本実施形態の容器１０によれば、切除前状態の蓋体２０同士を積み重ねると（図１１参照）、上側の蓋体２０の開封バンド部２１Ｘが下側の蓋体２０の平リブ３３群の外側に嵌合するので、上側の蓋体２０が横ズレすることが防がれる。これにより、蓋体２０同士を安定して段積みしておくことができるので、切除前状態の蓋体２０の保管が嵩張らずに行える。また、蓋体２０を容器本体１１に取り付ける作業において、蓋体２０を一つずつ手にとることがスムーズになり、作業効率が高められる。 In contrast, with the container 10 of this embodiment, when the lid bodies 20 in the pre-removal state are stacked on top of each other (see FIG. 11), the opening band portion 21X of the upper lid body 20 fits onto the outside of the group of flat ribs 33 of the lower lid body 20, preventing the upper lid body 20 from shifting sideways. This allows the lid bodies 20 to be stably stacked on top of each other, so that the lid bodies 20 in the pre-removal state can be stored without taking up too much space. Also, when attaching the lid bodies 20 to the container body 11, it becomes easier to pick up the lid bodies 20 one by one, improving work efficiency.

また、開封バンド部２１Ｘを切除して容器１０を開封した後にも、例えば容器１０をタッパーとして再利用するためだったり、廃棄のために、切除後状態の蓋体２０同士をまとめて保管しておくことが考えられるが、この場合であっても、切除後状態の蓋体２０同士を積み重ねると（図１２参照）、上側の蓋体２０の嵌合壁本体２１Ｙが下側の蓋体２０の平リブ３３群の外側に嵌合するので、切除後状態の蓋体２０同士を安定して段積みしておくことができ、保管が容易になる。しかも、切除前状態の蓋体２０では、嵌合壁２１の開封バンド部２１Ｘが外縁壁部３２の上面に当接するのに対し、切除後状態の蓋体２０では、嵌合壁本体２１Ｙが外縁壁部３２の上面に当接するので、開封バンド部２１Ｘを切除した後に、蓋体２０同士を段積みしたときの嵩を減らすこともできる。 In addition, even after the opening band portion 21X is cut off and the container 10 is opened, it is possible to store the lid bodies 20 in the cut-off state together, for example, to reuse the container 10 as a Tupperware or to dispose of it. Even in this case, when the lid bodies 20 in the cut-off state are stacked together (see FIG. 12), the fitting wall body 21Y of the upper lid body 20 fits on the outside of the flat ribs 33 of the lower lid body 20, so that the lid bodies 20 in the cut-off state can be stably stacked and stored easily. Moreover, in the lid body 20 before the cut-off state, the opening band portion 21X of the fitting wall 21 abuts on the upper surface of the outer edge wall portion 32, whereas in the lid body 20 in the cut-off state, the fitting wall body 21Y abuts on the upper surface of the outer edge wall portion 32, so that the bulk of the lid bodies 20 when stacked together after the opening band portion 21X is cut off can be reduced.

なお、容器１０を開封する際に、人によっては、開封バンド部２１Ｘを切除せずに、開封バンド部２１Ｘの下端部を無理矢理外方へ広げて蓋体２０を外すことも考えられる。これに対し、本実施形態によれば、図１５及び図１６に示すように、切除前状態のものと切除後状態のものとが混ざっていても、互いに段積みできるので、蓋体２０の保管の作業効率をより向上することができる。 When opening the container 10, some people may forcibly spread the lower end of the opening band portion 21X outward to remove the lid body 20 without cutting off the opening band portion 21X. In contrast, according to this embodiment, as shown in Figures 15 and 16, even if there is a mixture of pre-removal and post-removal states, the lid bodies 20 can be stacked on top of each other, which further improves the work efficiency of storing the lid bodies 20.

また、本実施形態では、蓋体２０同士を段積みするときに上側の蓋体２０と嵌合する箇所（平リブ３３群）が、容器１０同士を段積みするときに上側の容器１０と嵌合する箇所と兼用されているので、別個に設けるよりもデザインがシンプルになる。さらに、両者を兼用するために、平リブ３３が外縁壁部３２と内側陥没部３１とに跨って形成されるので平リブ３３の強度が高くなる。さらに、上方に切除後状態の蓋体２０が重ねられたときは、上段側の蓋体２０の内側陥没部３１の下面（底部３１Ｂの下面）が下段側の蓋体２０の平リブ３３の上端面３３Ａに当接して支持されるので、段積みが安定する。 In addition, in this embodiment, the portion (group of flat ribs 33) that engages with the upper lid 20 when the lids 20 are stacked also serves as the portion that engages with the upper container 10 when the containers 10 are stacked, resulting in a simpler design than if the portion was provided separately. Furthermore, in order to serve both purposes, the flat ribs 33 are formed across the outer edge wall portion 32 and the inner recessed portion 31, increasing the strength of the flat ribs 33. Furthermore, when the lid 20 in the post-removal state is stacked on top, the lower surface (lower surface of the bottom portion 31B) of the inner recessed portion 31 of the upper lid 20 is supported by abutting against the upper end surface 33A of the flat rib 33 of the lower lid 20, resulting in a stable stack.

さらに、切除前状態と切除後状態との両方において、上段側の蓋体２０が下段側の蓋体２０の平リブ３３群の外側に嵌合するので、例えば、作業者が、上段側の蓋体２０を斜めにして、その下側に配された一辺の嵌合壁２１を下段側の蓋体２０の平リブ３３の外側端面３３Ｃにあてて回動させることで蓋体２０を段積みする場合、切除前状態と切除後状態との両方で、同じように作業できるため、切除前状態か切除後状態かによって平リブ３３群の外側に嵌合するか内側に嵌合するか異なる場合と比べて、作業が容易となる。 Furthermore, in both the pre-resection state and the post-resection state, the upper lid body 20 fits onto the outside of the group of flat ribs 33 of the lower lid body 20. For example, when an operator tilts the upper lid body 20 and rotates it so that the fitting wall 21 on one side of the upper lid body 20 is placed against the outer end surface 33C of the flat rib 33 of the lower lid body 20, the same work can be done in both the pre-resection state and the post-resection state, making the work easier than when the lid body 20 fits onto the outside or inside of the group of flat ribs 33 depending on whether it is in the pre-resection state or the post-resection state.

しかも、平リブ３３の外側端面３３Ｃは、嵌合壁２１の外側面の延長線上よりも内側に位置していて、上側の蓋体２０の嵌合壁２１（開封バンド部２１Ｘ又は嵌合壁本体２１Ｙ）が、下側の蓋体２０の外縁壁部３２の上面（曲面３２Ａ）に当接するので、段積みされた複数の蓋体２０群全体の外側面の凹凸を抑えることができる。これにより、蓋体２０群の外側面に何かが引っ掛かり、段積みが崩れることが抑制される。 In addition, the outer end surface 33C of the flat rib 33 is located inside the extension line of the outer surface of the mating wall 21, and the mating wall 21 (opening band portion 21X or mating wall main body 21Y) of the upper lid body 20 abuts against the upper surface (curved surface 32A) of the outer edge wall portion 32 of the lower lid body 20, so unevenness of the outer surface of the entire group of multiple stacked lid bodies 20 can be reduced. This prevents the outer surface of the group of lid bodies 20 from getting caught on anything and causing the stack to collapse.
