Description

本発明は、物流時や店頭販売時に複数個積み重ね可能な包装用容器の蓋体に関するものである。   The present invention relates to a lid of a packaging container that can be stacked in plural at the time of physical distribution or over-the-counter sales.

従来から、スーパーマーケット・コンビニエンスストア・デパート等の小売店では、所定の食品を包装用容器に収納して店頭販売していた。このとき、包装用容器には、消費者が容器本体に収納される食品を蓋体越しに見えやすくしたり、容器本体及び／又は蓋体が物流時や販売時の衝撃や圧迫により破損しにくくしたり、全体的に陳列時の配置スペースを節約したりする工夫が施されていた。すなわち、商品価値の向上を図るためには、食品のみならず包装用容器の改善が求められていた。   Conventionally, retail stores such as supermarkets, convenience stores, department stores, etc., store predetermined foods in packaging containers and sell them over the counter. At this time, the packaging container makes it easier for consumers to see the food stored in the container body through the lid, or the container body and / or the lid is less likely to be damaged due to shock or pressure during distribution or sales. And an overall idea of saving the arrangement space at the time of display. That is, in order to improve the commercial value, there has been a demand for improvement of packaging containers as well as food.

例えば、包装用容器を上下に複数個積み重ね可能にする場合、荷崩れ防止のため下側の蓋体の天面部分に上側の容器本体の脚部分が納まる構造が採用されてきた。詳細には、天面部分の四つ角部分が突出された凸部分より内寄りに上側の容器本体の脚部分が納まる構造や、天面部分の四つ角部分が陥没された凹部分に上側の容器本体の脚部分が納まる構造である。しかしながら、前者では下側の蓋体の天面部分に上側の容器本体の全重量が加わるため、天面部分がつぶれてしまう恐れがあった。また、前者では天面部分の四つ角部分が突出しており、後者では天面部分の四つ角部分が陥没しているため、消費者が容器本体に収納される食品を天面部分越しに見え難くなる恐れがあった。   For example, when a plurality of packaging containers can be stacked one above the other, a structure has been adopted in which the leg portion of the upper container body is accommodated in the top surface portion of the lower lid in order to prevent collapse of the load. Specifically, a structure in which the leg portion of the upper container body fits inwardly from the convex portion from which the four corner portions of the top surface portion are projected, or a concave portion in which the four corner portions of the top surface portion are recessed, It is a structure that fits the leg. However, in the former, since the total weight of the upper container body is added to the top surface portion of the lower lid, the top surface portion may be crushed. Also, in the former, the four corners of the top surface portion protrude, and in the latter, the four corner portions of the top surface portion are depressed, so that consumers may not easily see the food stored in the container body over the top surface portion. was there.

そこで、蓋体の天面部分を支持する側壁部分で構成される四つのコーナー部分を跨って膨出し、かつ天面部分より高さの低い脚支持部分に上側の容器本体の脚部分が納まる構造が提案されている（例えば、特許文献１参照。）。すなわち、上側の容器本体の脚部分が下側の蓋体の天面部分を囲って脚支持部に納まるため、天面部分に容器本体の重量が加わらずつぶれる心配がなくなると共に、蓋体の天面部分の四つ角部分に凸部分又は凹部分がないため、消費者が容器本体に収納される食品を天面部分越しに見えやすくなるものである。   Therefore, a structure in which the leg portion of the upper container body is accommodated in a leg support portion that swells over four corner portions constituted by side wall portions that support the top surface portion of the lid and is lower than the top surface portion. Has been proposed (see, for example, Patent Document 1). That is, since the leg portion of the upper container body surrounds the top surface portion of the lower lid body and fits in the leg support portion, the weight of the container body is not added to the top surface portion and there is no fear of crushing, and the top surface of the lid body is eliminated. Since there are no convex portions or concave portions in the four corner portions of the surface portion, the consumer can easily see the food stored in the container body over the top surface portion.

特許第５８７６１０１号公報Japanese Patent No. 5876101

しかしながら、上述した特許文献１の包装用容器の蓋体では、蓋体の側壁部分越しに容器本体内部が見え難い恐れがある。すなわち、蓋体の脚支持部分が側壁部分のコーナー部分を跨っているため、側壁部分の側面の両端から天面部分と脚支持部分との段差を含む脚支持部分の一部が突出しており、包装用容器の正面視又は側面視にて容器本体内部を視認する消費者にとっての障害となり得る。   However, in the lid of the packaging container of Patent Document 1 described above, the inside of the container body may be difficult to see through the side wall portion of the lid. That is, since the leg support part of the lid straddles the corner part of the side wall part, a part of the leg support part including the step between the top surface part and the leg support part protrudes from both ends of the side surface of the side wall part, This may be an obstacle for consumers who visually recognize the inside of the container main body in a front view or a side view of the packaging container.

近年では、容器本体の形状に応じた食品の盛り付けや店頭販売に応じた商品の陳列も様々であり、蓋体の天面部分越しのみならず、側壁部分越しから容器本体の内部を視認する場合もある。例えば、容器本体内部の中央部分のみならず端部分に至って食品が盛り付けられる場合や端部分から中央部分に向かって食品が並べられる場合、蓋体の天面部分越しからでは容器内部の端部分に盛られた食品が見え難いため、側壁部分の側面の少なくとも一端側には、容器本体の脚支持部分を形成する凸部分又は凹部分のない構造にすべきである。   In recent years, food display according to the shape of the container body and display of products according to over-the-counter sales are also various, and when the inside of the container body is viewed not only through the top surface part of the lid but also through the side wall part There is also. For example, when food is served not only at the center part inside the container body but also at the end part, or when foods are arranged from the end part toward the center part, from the top surface part of the lid body, the end part inside the container Since the accumulated food is difficult to see, at least one end of the side surface of the side wall portion should have a structure that does not have a convex portion or a concave portion that forms the leg support portion of the container body.

さらに、蓋体の上に積み重なる容器本体にとって、水平方向への位置ずれや蓋体方向（下方向）への沈み込みが生じなければ、蓋体の脚支持部分がコーナー部分を跨っている必要性は低い。すなわち、蓋体の脚支持部分が、上側の包装用容器の加重により破損等せず載置状態を維持できれば、蓋体の側壁部分の側面のみに脚支持部分が設けられてもよく、屈曲部分など成形上の問題が生じやすい部分を含むべきでない。   Furthermore, for the container body stacked on the lid, the leg support part of the lid needs to straddle the corner if there is no horizontal displacement and no sinking in the lid direction (downward) Is low. That is, the leg support portion may be provided only on the side surface of the side wall portion of the lid, and the bent portion may be provided as long as the leg support portion of the lid can be maintained without being damaged by the weight of the upper packaging container. It should not contain parts that are prone to molding problems.

そこで、本発明の目的は、容器本体内部を正面方向及び／又は側面方向から視認可能かつ上から容器本体の積み重ね可能な構造を有する包装用容器の蓋体を提供することにある。   Therefore, an object of the present invention is to provide a lid for a packaging container having a structure in which the inside of the container body can be viewed from the front direction and / or the side direction and the container body can be stacked from above.

上記課題を解決するために、本発明による包装用容器の蓋体は、略矩形状の天面部と、上記天面部の周縁から下方に拡開して連接される側壁部とを少なくとも有し、上記側壁部は、複数の側面部と、隣接する側面部同士で構成される角部とを有し、上記隣接する側面部の少なくとも一方は、上記天面部より低い位置から下端に渡って外方に張り出される張出部を有し、上記張出部は、上記角部より上記側面部の中央寄りに設けられていることを特徴としてもよい。   In order to solve the above problems, the lid of the packaging container according to the present invention has at least a substantially rectangular top surface portion, and at least a side wall portion that is expanded and connected downward from the periphery of the top surface portion, The side wall portion has a plurality of side surface portions and a corner portion constituted by adjacent side surface portions, and at least one of the adjacent side surface portions is outward from a position lower than the top surface portion to the lower end. It is good also as the above-mentioned overhang | projection part being provided near the center of the said side part from the said corner | angular part.

また、上記天面部が、略長方形状で、上記側壁部が、一対の長尺側面部及び一対の短尺側面部を有し、上記張出部が、上記長尺側面部の各々又は上記短尺側面部の各々の両端部分に設けられていてもよい。   Further, the top surface portion is substantially rectangular, the side wall portion has a pair of long side surface portions and a pair of short side surface portions, and the overhanging portion is each of the long side surface portions or the short side surfaces. It may be provided at both end portions of each part.

また、上記天面部が、略正方形状で、上記張出部が、対向する上記側面部の各々の点対称部分に設けられていてもよい。   Moreover, the said top surface part is substantially square shape, and the said overhang | projection part may be provided in each point symmetrical part of the said side part which opposes.

また、上記張出部が、上部より下部の幅が広くかつ張出量が少ない形状であってもよい。   Further, the protruding portion may have a shape in which the lower portion is wider than the upper portion and the protruding amount is small.

また、本発明による包装用容器は、上記蓋体が装着される容器本体をさらに備え、上記容器本体は、底部の裏面の四隅近傍から突出される略Ｌ字状の脚部を少なくとも有し、上記蓋体は、上記天面部の角部分に上記容器本体と同形状の容器本体の脚部を嵌め、かつ上記張出部に上記脚部を当接させて上記容器本体を積載可能とすることを特徴としてもよい。   The packaging container according to the present invention further includes a container main body to which the lid is mounted, and the container main body has at least substantially L-shaped legs protruding from the vicinity of the four corners of the back surface of the bottom. The lid body can be loaded with the container main body by fitting the leg portion of the container main body having the same shape as the container main body to the corner portion of the top surface portion and bringing the leg portion into contact with the overhanging portion. May be a feature.

本発明による包装用容器の蓋体は、隣接する側面部の少なくとも一方、かつ角部より中央寄りに張出部を有することにより、平面視で天面部に対して四方に張出部が配されるため、容器本体の脚部分を張出部に当接させて蓋体の上に積み重ねることができるのみならず、側面部越しから容器本体内部を視認しやすくすることができる。すなわち、張出部は側壁部の角部を跨っていないため、側面部から容器本体内部の視認を妨げる障害物を少なくしつつ、別の容器本体を安定して積み重ねられる効果が期待できる。   The lid of the packaging container according to the present invention has an overhanging portion in four directions with respect to the top surface portion in a plan view by having an overhanging portion at least one of the adjacent side surface portions and closer to the center than the corner portion. Therefore, not only can the leg portion of the container main body be brought into contact with the overhanging portion and stacked on the lid body, but also the inside of the container main body can be easily seen from the side portion. That is, since the overhanging portion does not straddle the corner portion of the side wall portion, an effect of stably stacking another container body can be expected while reducing obstacles that hinder the visual recognition of the inside of the container body from the side surface portion.

また、略長方形状の天面部に連接される側壁部が有する長尺側面部の各々及び短尺側面部の各々の両端部分に張出部が設けられていることにより、隣接する他方の側面部越しから容器本体内部を視認しやすくすることができる。すなわち、長尺側面部（又は短尺側面部）に張出部が配されれば、短尺側面部（又は長尺側面部）には容器本体内部の視認を妨げる障害物が存在しないため、長手方向（又は短手方向）に沿って並べられた食品を見えやすくする効果が期待できる。   In addition, each of the long side surface portions of the side wall portion connected to the substantially rectangular top surface portion and the both side portions of the short side surface portions are provided with overhang portions so that the other side surface portion is overlaid. Therefore, the inside of the container body can be easily seen. That is, if the overhanging portion is arranged on the long side surface portion (or short side surface portion), the short side surface portion (or long side surface portion) has no obstacle that obstructs the visual recognition of the inside of the container body. The effect which makes the food arranged along (or short direction) easy to see can be expected.

また、略正方形状の天面部に連接される側壁部が有する対向する側面部の各々の点対称部分に張出部が設けられることにより、いずれの側面部越しから容器本体内部を視認しやすくすることができると共に、蓋体の向きに限定せず容器本体に装着することができる。すなわち、張出部以外に各側面部には容器本体内部の視認を妨げる障害物が存在しないため、四方から食品を見えやすくする効果が期待できる。   In addition, by providing an overhanging portion at each point-symmetrical portion of the opposing side surface portions of the side wall portion connected to the substantially square top surface portion, it is easy to visually recognize the inside of the container body from any side surface portion. And can be attached to the container body without being limited to the direction of the lid. That is, since there is no obstacle that obstructs the visual recognition of the inside of the container main body on each side surface other than the overhanging portion, it is possible to expect the effect of making food easily visible from all sides.

また、張出部が、上部より下部の幅が広くかつ張出量が少ない形状であることにより、簡易な構造で所望の剛性を有する上側の容器本体を指示する土台を形成することができる。すなわち、張出部のうち、側面部から突出した上端部分に上側の容器本体の脚部分が当接し、容器本体からの加重を側壁部より急勾配の正面部分かつ幅広な下部が支持するため、張出部の上端部分が狭くても容器本体を安定して積み重ねられる効果が期待できる。   In addition, since the overhanging portion has a shape in which the width of the lower portion is wider than the upper portion and the amount of overhanging is small, it is possible to form a base that indicates the upper container body having a desired rigidity with a simple structure. That is, the leg portion of the upper container body abuts on the upper end portion protruding from the side surface portion of the overhanging portion, and the load from the container body is supported by the front portion and the wide lower portion that are steeper than the side wall portion, Even if the upper end portion of the overhanging portion is narrow, an effect of stably stacking the container body can be expected.

また、本発明による包装用容器は、上述した蓋体が装着される容器本体の底部裏面の四隅近傍から突出される略Ｌ字状の脚部が、別の蓋体の天面部角部分に嵌り、かつ張出部に当接することにより、水平方向への位置ずれを予防することができるため、安定して積み重ねられる効果が期待できる。   Further, in the packaging container according to the present invention, the substantially L-shaped leg portions protruding from the vicinity of the four corners of the bottom back surface of the container main body to which the above-described lid body is mounted fits into the corner portion of the top surface portion of another lid body. And since it can prevent the position shift to a horizontal direction by contact | abutting to an overhang | projection part, the effect accumulated stably can be anticipated.

It is good.

次に、図１〜図５を参照しつつ、蓋体１の一例の詳細な構造を説明する。   Next, a detailed structure of an example of the lid 1 will be described with reference to FIGS.

蓋体１は、平面視で略長方形状かつ平坦状の天面部１１と、この天面部の周縁から下方に拡開して連接される平坦状の蓋体側壁部１２と、この蓋体側壁部の下端の周縁から外方に延出している蓋体フランジ部１３とを有していてもよい。
なお、天面部１１は、各辺が直線状又は外側に緩やかに湾曲した形状でもよく、平面視で略正方形状、略円形状、又は略楕円形状でもよく、限定はない。蓋体側壁部１２は、各々の壁面部分が外側に緩やかに膨出していてもよい。蓋体フランジ部１３には、容器本体２と外嵌合する嵌合部分が設けられてもよい。 The lid body 1 has a substantially rectangular and flat top surface portion 11 in a plan view, a flat lid side wall portion 12 that is expanded and connected downward from the periphery of the top surface portion, and the lid side wall portion. And a lid flange portion 13 that extends outward from the peripheral edge of the lower end.
The top surface portion 11 may have a shape in which each side is linear or gently curved outward, and may have a substantially square shape, a substantially circular shape, or a substantially oval shape in plan view, and is not limited. As for the lid body side wall part 12, each wall surface part may bulge gently outside. The lid flange portion 13 may be provided with a fitting portion that is externally fitted to the container body 2.

蓋体側壁部１２は、本包装用容器の通常の向きにおいて、長手方向に配される一対の長尺側面部１２１と、短手方向に配される一対の短尺側面部１２２と、隣接するこの長尺側面部と短尺側面部とで構成される四つの角部１２３とを有していてもよい。長尺側面部１２１は、天面部１１より低い位置から下端に渡って外方に張り出される張出部１２１ａをそれぞれ相対する位置に有していてもよい。この構造によれば、短尺側面部１２２に張出部１２１ａがないため、消費者が容器本体２の手前側からこの短尺側面部越しに内部を視認しやすくなってもよい。
なお、長尺側面部１２１及び短尺側面部１２２の形状及び寸法、並びにこの長尺側面部とこの短尺側面部との長さの比率に限定はない。角部１２３の角度は、略直角でもよく、所定の面取り半径にて屈曲していてもよい。 The lid side wall portion 12 is adjacent to a pair of long side surface portions 121 arranged in the longitudinal direction and a pair of short side surface portions 122 arranged in the short direction in the normal direction of the packaging container. You may have four corner | angular parts 123 comprised by a long side part and a short side part. The long side surface portion 121 may have overhang portions 121a that protrude outward from a position lower than the top surface portion 11 to the lower end, respectively. According to this structure, since the short side portion 122 does not have the overhang portion 121a, the consumer may easily see the inside from the near side of the container body 2 through the short side portion.
In addition, there is no limitation in the shape and dimension of the long side part 121 and the short side part 122, and the ratio of the length of this long side part and this short side part. The angle of the corner 123 may be substantially a right angle or may be bent at a predetermined chamfer radius.

張出部１２１ａは、角部１２３より長尺側面部１２１の中央寄りかつ両端に設けられていてもよい。換言すると、張出部１２１ａは、角部１２３の頂上部分から屈曲している部分までの範囲内に差し掛かっておらず、かつこの角部と長尺側面部１２１との境界からこの長尺側面部の中央寄りかつ両端に設けられていてもよい。この構造によれば、張出部１２１ａは角部１２３以外の長尺側面部１２１に設けられるため、成形しやすい上、所望の剛性を得ることができる。
張出部１２１ａの形状は、上端より下端が幅広で、かつ上端側より下端側の膨出量が少ない形状でもよい。換言すると、張出部１２１ａは、長尺側面部１２１の正面視方向から見て略台形状で、この長尺側面部の側面視方向（短尺側面部１２２の正面視方向）から見て、この長尺側面部より張出部分の傾斜が急な形状でもよい。この構造によれば、蓋体１の上に積み重ねた別の容器本体の脚部が張出部１２１ａの上端部分に載りやすく、上側の包装用容器の沈み込みを防止してもよい。
なお、張出部１２１ａの形状に限定はなく、長尺側面部１２１の正面視方向から見て略長方形状でも上端部分が平坦状の円弧形状でもよい。張出部１２１ａの数は、長尺側面部１２１の両端のみならず、これらの中間部分に単数又は複数設けられてもよい。張出部１２１ａの張出部分の傾斜は、長尺側面部１２１より緩やか又は同等でもよい。天面部１１が略正方形状の場合、張出部１２１ａが風車状（同寸法の側面部１２１及び１２２の同じ側の端部）に配されてもよい。 The overhanging portion 121a may be provided closer to the center of the long side surface portion 121 than the corner portion 123 and at both ends. In other words, the overhanging portion 121a does not reach the range from the top portion of the corner portion 123 to the bent portion, and the long side surface portion from the boundary between the corner portion and the long side surface portion 121. It may be provided near the center and at both ends. According to this structure, since the overhanging portion 121a is provided on the long side surface portion 121 other than the corner portion 123, it can be easily molded and desired rigidity can be obtained.
The shape of the overhanging portion 121a may be a shape in which the lower end is wider than the upper end and the bulging amount on the lower end side is smaller than the upper end side. In other words, the overhanging portion 121a is substantially trapezoidal when viewed from the front view direction of the long side surface portion 121, and is viewed from the side view direction of the long side surface portion (front view direction of the short side surface portion 122). The protruding portion may have a steeper shape than the long side surface portion. According to this structure, the leg portion of another container body stacked on the lid body 1 may easily be placed on the upper end portion of the overhang portion 121a, and the upper packaging container may be prevented from sinking.
The shape of the overhanging portion 121a is not limited, and may be a substantially rectangular shape or a circular arc shape having a flat upper end portion when viewed from the front side of the long side surface portion 121. The number of the overhanging portions 121a may be provided not only at both ends of the long side surface portion 121 but also at an intermediate portion thereof. The slope of the overhang portion of the overhang portion 121a may be more gradual or equivalent than that of the long side surface portion 121. When the top surface portion 11 has a substantially square shape, the overhang portion 121a may be arranged in a windmill shape (end portions on the same side of the side surface portions 121 and 122 having the same dimensions).

次に、図６〜図１０を参照しつつ、容器本体２の一例の詳細な構造を説明する。   Next, a detailed structure of an example of the container body 2 will be described with reference to FIGS.

容器本体２は、食品が載置される平面視で略長方形状の載置部２１と、この底部の周縁を囲っている本体側壁部２２と、この載置部とこの本体側壁部との間に一体的に形成される脚部２３と、この本側壁部の上端から外方に延出している本体フランジ部２４とを有していてもよい。
なお、載置部２１は、平面視で略正方形状、略円形状、又は略楕円形状でもよく、限定はない。載置部２１と本体側壁部２２との間隔は、所定の幅の脚部２３が設けられる程度でよく、限定はない。本体側壁部２２は、下から上に向かって拡開している形状でもよい。本体フランジ部２４には、蓋体１と外嵌合方式で嵌合する嵌合部分が設けてあってもよい。 The container body 2 includes a placing portion 21 having a substantially rectangular shape in plan view on which food is placed, a body side wall portion 22 surrounding the periphery of the bottom portion, and a space between the placing portion and the body side wall portion. May be provided with a leg portion 23 formed integrally with the main body flange portion 24 and a main body flange portion 24 extending outward from the upper end of the side wall portion.
In addition, the mounting part 21 may have a substantially square shape, a substantially circular shape, or a substantially oval shape in plan view, and is not limited. The space between the mounting portion 21 and the main body side wall portion 22 is not limited as long as the leg portion 23 having a predetermined width is provided. The main body side wall 22 may have a shape expanding from the bottom to the top. The main body flange portion 24 may be provided with a fitting portion that is fitted to the lid body 1 by an external fitting method.

載置部２１は、本包装用容器の通常の向きにて手前側から奥側に向かって斜め上方に緩やかに湾曲して膨出している略長方形状の載置面部２１１と、この載置面部の周縁から下方に拡開して設けられている載置面支持部２１２とを有していてもよい。この構造によれば、載置面部２１１が載置面支持部２１２により所定の高さ及び角度で支持されることで、消費者に対して食品を見せやすくしてもよい。
なお、載置面部２１１は、平面視で略長方形状、略円形状、又は略楕円形状でもよく、手前側から奥側に向かって平坦な斜面状でもよい。載置面部２１１の表面には、載置される食品の位置ずれ（滑り）を予防したり載置場所や載置量の目印にしたりする棒状のリブ（符番しない）が設けられていてもよい。 The mounting portion 21 includes a substantially rectangular mounting surface portion 211 that is gently curved and bulged obliquely upward from the near side toward the back side in the normal direction of the packaging container, and the mounting surface portion. There may be provided a mounting surface support portion 212 that is provided so as to expand downward from the periphery thereof. According to this structure, the placing surface portion 211 may be supported by the placing surface support portion 212 at a predetermined height and angle so that the food can be easily shown to the consumer.
In addition, the mounting surface portion 211 may have a substantially rectangular shape, a substantially circular shape, or a substantially oval shape in plan view, or may have a flat slope shape from the near side to the far side. Even if the surface of the mounting surface portion 211 is provided with a rod-shaped rib (not numbered) that prevents the displacement (slipping) of the food to be mounted or serves as a mark for the mounting location or the loading amount. Good.

脚部２３は、載置面支持部２１２と、この載置面支持部の下端から上方に拡開して設けられる本体側壁部２２とで形成されていてもよい。脚部２３の位置は、少なくとも容器本体２の四隅に配され、さらに四隅に配された脚部の各々の間に別の脚部が配されてもよい。脚部２３の形状は、容器本体２の四隅の角部分に一致する略Ｌ字状や、この容器本体の長手方向又は短手方向に平行な略直線状でもよい。脚部２３の端面形状は、本体フランジ部２４に直交する方向の切断面において略Ｖ字状でもよい。この構造によれば、脚部２３の内周の形状及び寸法と一致する蓋体１の上に、別の容器本体を安定的に積み重ねてもよい。
脚部２３の各々の間には、容器本体２の剛性を高める補強部２３１が設けられてもよい。補強部２３１は、載置面部２１１より低く、かつ載置面支持部２１２の所定の高さから外方に延出して本体側壁部２２と連接されてもよい。補強部２３１の端面形状は、本体フランジ部２４と平行な切断面において下向きに凹んだ矩形状や円弧状でもよい。この構造によれば、容器本体２に加わるねじれ等の外力に対し、補強部２３１が載置面部２１１や本体側壁部２２の破損を防止してもよい。
なお、脚部２３の形状及び寸法に限定はなく、例えば、この脚部を形成する略Ｌ字状の一方が他方より長くても双方同等の長さでもよい。補強部２３１の形状及び寸法に限定はない。 The leg portion 23 may be formed of a placement surface support portion 212 and a main body side wall portion 22 that is provided so as to expand upward from the lower end of the placement surface support portion. The positions of the leg portions 23 may be arranged at least at the four corners of the container main body 2, and another leg portion may be arranged between each of the leg portions arranged at the four corners. The shape of the leg portion 23 may be a substantially L shape that coincides with the corners of the four corners of the container body 2 or a substantially straight line that is parallel to the longitudinal direction or the short direction of the container body. The end face shape of the leg portion 23 may be substantially V-shaped on the cut surface in the direction orthogonal to the main body flange portion 24. According to this structure, another container body may be stably stacked on the lid body 1 that matches the shape and size of the inner periphery of the leg portion 23.
A reinforcing portion 231 that increases the rigidity of the container body 2 may be provided between the leg portions 23. The reinforcing portion 231 may be lower than the placement surface portion 211 and extend outward from a predetermined height of the placement surface support portion 212 to be connected to the main body side wall portion 22. The end surface shape of the reinforcing portion 231 may be a rectangular shape or an arc shape that is recessed downward on a cut surface parallel to the main body flange portion 24. According to this structure, the reinforcing portion 231 may prevent the mounting surface portion 211 and the main body side wall portion 22 from being damaged by an external force such as a twist applied to the container main body 2.
The shape and dimensions of the leg portion 23 are not limited. For example, one of the substantially L-shapes forming the leg portion may be longer than the other, or the length may be the same. There is no limitation on the shape and size of the reinforcing portion 231.

次に、図１１を参照しつつ、２つの本包装用容器が上下に積み重なった状態における蓋体及び容器本体の関係について説明する。   Next, the relationship between the lid body and the container body in a state where two main packaging containers are stacked one above the other will be described with reference to FIG.

下側となる蓋体１の天面部１１の外周縁に上側となる容器本体２の底部２１の四隅に配される脚部２３の内周縁が着脱自在に嵌ってもよく、この脚部の底部分がこの蓋体の蓋体側壁部１２を構成する一対の長尺側面部１２１に設けられる張出部１２１ａの各々の上端部分に当接してもよい。すなわち、容器本体２は蓋体１の張出部１２１ａに載置され、この蓋体の天面部１１とこの容器本体の底部２１との間に所定の隙間が生じるため、この天面部はこの容器本体からの加重を受けずに形状変形しない状態でもよい。   The inner peripheral edge of the leg part 23 arranged at the four corners of the bottom part 21 of the container body 2 on the upper side may be detachably fitted to the outer peripheral edge of the top surface part 11 of the lid body 1 on the lower side. The portion may abut on the upper end portion of each of the protruding portions 121a provided on the pair of long side surface portions 121 constituting the lid side wall portion 12 of the lid body. That is, the container body 2 is placed on the overhanging portion 121a of the lid body 1, and a predetermined gap is generated between the top surface portion 11 of the lid body and the bottom portion 21 of the container body. It may be in a state where the shape is not deformed without receiving a weight from the main body.

さらに、脚部２３は略Ｌ字状であり、この脚部の内側の角部分と蓋体１の蓋体側壁部１２で構成される各々の角部１２３とが略一致して引っ掛かるため、この容器本体が水平方向に位置ずれし難い状態でもよい。このとき、容器本体２の脚部２３のうち、蓋体２の張出部１２１ａの上端部分に当接していない部分が宙に浮いていても（この部分が所定の部位で支持されていなくても）、この張出部の各々は一対の長尺側面部１２１の両端かつ蓋体側壁部１２で構成される各々の角部１２３より中央寄りに位置するため、容器本体２は安定した載置状態を維持してもよい。   Further, the leg portion 23 is substantially L-shaped, and the corner portion on the inner side of the leg portion and each corner portion 123 formed by the lid body side wall portion 12 of the lid body 1 are substantially coincident with each other. The container main body may be in a state where it is difficult to be displaced in the horizontal direction. At this time, even if the portion of the leg portion 23 of the container body 2 that is not in contact with the upper end portion of the overhanging portion 121a of the lid body 2 is suspended in the air (this portion is not supported by a predetermined portion). In addition, since each of the overhanging portions is positioned closer to the center than each corner portion 123 formed by both ends of the pair of long side surface portions 121 and the lid side wall portions 12, the container body 2 can be stably placed. The state may be maintained.

このような蓋体１の構造は、複数の包装用容器の積み重ねを実現させるのみならず、容器本体２が積み重なっていない状態にて消費者の購買意欲の向上への寄与が期待できる。すなわち、蓋体１の天面部１１には容器本体２の脚部２３が載置するための凹凸部分がないばかりでなく、蓋体側壁部１２の短尺側面部１２２には長尺側面部１２１の張出部１２１ａなどこの脚部を支持する凸部分がないため、この天面部越し及び／又はこの短尺側面部越しから容器本体２の内部を消費者が視認しやすく購買欲求を高める効果が期待できる。   Such a structure of the lid body 1 not only realizes the stacking of a plurality of packaging containers, but can be expected to contribute to the improvement of consumers' willingness to purchase in a state where the container body 2 is not stacked. That is, the top surface portion 11 of the lid body 1 does not have an uneven portion for placing the leg portion 23 of the container body 2, and the short side surface portion 122 of the lid body side wall portion 12 has the long side surface portion 121. Since there is no convex portion that supports the leg portion such as the overhanging portion 121a, the consumer can easily see the inside of the container main body 2 through the top surface portion and / or the short side surface portion, and the effect of increasing purchase desire can be expected. .

このように、本実施形態における包装用容器の蓋体１は、隣接する側面部１２１及び１２２の少なくとも一方、かつ角部１２３より中央寄りに張出部１２１ａを有することにより、平面視で天面部１１に対して四方にこの張出部が配されるため、容器本体２の脚部２３をこの張出部に当接させてこの蓋体の上に積み重ねることができるのみならず、この側面部越しからこの容器本体内部を視認しやすくすることができる。すなわち、張出部１２１ａは側壁部１２の角部１２３を跨っていないため、側面部１２１及び１２２から容器本体２内部の視認を妨げる障害物を少なくしつつ、別の容器本体を安定して積み重ねられる効果が期待できる。   As described above, the lid 1 of the packaging container according to the present embodiment has the protruding portion 121a closer to the center than at least one of the adjacent side surface portions 121 and 122 and the corner portion 123, so that the top surface portion is seen in plan view. 11, the overhanging portion is arranged in four directions, so that the leg portion 23 of the container body 2 can be brought into contact with the overhanging portion and stacked on the lid body. The inside of the container main body can be easily seen from above. That is, since the overhanging portion 121a does not straddle the corner portion 123 of the side wall portion 12, another container body can be stably stacked while reducing the obstacles that hinder the visual recognition of the inside of the container body 2 from the side surfaces 121 and 122. Can be expected.

また、略長方形状の天面部１１に連接される側壁部１２が有する長尺側面部１２１の各々及び短尺側面部１２２の各々の両端部分に張出部１２１ａが設けられていることにより、隣接する他方の側面部越しから容器本体２内部を視認しやすくすることができる。すなわち、長尺側面部１２１（又は短尺側面部１２２）に張出部１２１ａが配されれば、短尺側面部１２２（又は長尺側面部１２１）には容器本体２内部の視認を妨げる障害物が存在しないため、長手方向（又は短手方向）に沿って並べられた食品を見えやすくする効果が期待できる。   Moreover, it has adjoining by providing the overhang | projection part 121a in each both ends of each of the long side part 121 which the side wall part 12 connected to the substantially rectangular top surface part 11 has, and each short side part 122. The inside of the container main body 2 can be easily seen from the other side surface portion. That is, if the overhanging part 121a is arranged on the long side surface part 121 (or the short side surface part 122), the short side surface part 122 (or the long side surface part 121) has an obstacle that prevents the inside of the container body 2 from being visually recognized. Since it does not exist, the effect which makes the food arranged along the longitudinal direction (or short direction) easy to see can be expected.

また、略正方形状の天面部１１に連接される側壁部１２が有する対向する側面部１２１及び１２２の各々の点対称部分に張出部１２１ａが設けられることにより、いずれの側面部越しから容器本体２内部を視認しやすくすることができると共に、蓋体１の向きに限定せずこの容器本体に装着することができる。すなわち、張出部１２１ａ以外に各側面部には容器本体２内部の視認を妨げる障害物が存在しないため、四方から食品を見えやすくする効果が期待できる。   In addition, the overhanging portion 121a is provided at each point-symmetrical portion of the opposing side surface portions 121 and 122 that the side wall portion 12 connected to the substantially square top surface portion 11 has, thereby allowing the container body to extend from any side surface portion. 2 It is possible to make the inside easily visible, and it is possible to attach to the container body without being limited to the direction of the lid 1. That is, since there is no obstacle that obstructs the visual recognition of the inside of the container body 2 on each side surface other than the overhanging portion 121a, it is possible to expect the effect of making the food visible from four directions.

また、張出部１２１ａが、上部より下部の幅が広くかつ張出量が少ない形状であることにより、簡易な構造で所望の剛性を有する上側の容器本体２を指示する土台を形成することができる。すなわち、張出部１２１ａのうち、側面部１２１及び／又は１２２から突出した上端部分に上側の容器本体２の脚部２３が当接し、この容器本体からの加重をこの側壁部より急勾配の正面部分かつ幅広な下部が支持するため、この張出部の上端部分が狭くても容器本体を安定して積み重ねられる効果が期待できる。   In addition, since the overhang portion 121a has a shape in which the width of the lower portion is wider than the upper portion and the amount of overhang is small, it is possible to form a base that indicates the upper container body 2 having a desired rigidity with a simple structure. it can. That is, the leg portion 23 of the upper container body 2 abuts the upper end portion protruding from the side surface portions 121 and / or 122 of the overhanging portion 121a, and the load from the container body is steeper than the side wall portion. Since the part and the wide lower part support, even if the upper end part of this overhang | projection part is narrow, the effect that a container main body can be piled up stably can be expected.

本実施形態における包装用容器は、蓋体１が装着される容器本体２の載置部２１の四隅近傍から突出される略Ｌ字状の脚部２３が、別の蓋体の天面部１１角部分に嵌り、かつ張出部１２１ａに当接することにより、水平方向への位置ずれを予防することができるため、安定して積み重ねられる効果が期待できる。   In the packaging container according to the present embodiment, the substantially L-shaped leg portions 23 protruding from the vicinity of the four corners of the placement portion 21 of the container body 2 to which the lid body 1 is mounted are the top surface portion 11 corners of another lid body. Since the position shift in the horizontal direction can be prevented by fitting into the portion and contacting the overhanging portion 121a, an effect of being stably stacked can be expected.

なお、本実施形態による蓋体１や容器本体２は、例えば真空成形、圧空成形、真空圧空成形、両面真空成形、熱板成形等のシート成形で、合成樹脂シートを熱成形することにより形成されてもよい。合成樹脂シートとしては、例えば、ポリエチレンテレフタレート等のポリエステル系樹脂、ポリスチレン等のスチレン系樹脂、ポリプロピレン等のオレフィン系樹脂で、単層や多層のシートを使用してもよい。樹脂としては、例えば、発泡樹脂を使用すれば、軽量かつ断熱性があり好ましい。さらに、シートの表面または裏面を合成樹脂フィルムで覆ってもよく、表面を覆った場合は印刷を施してもよい。合成樹脂シートの厚みは特に制限はないが、０．１５〜０．５ｍｍであればよく、好ましくは０．１８〜０．４５ｍｍ、より好ましくは０．２〜０．３５ｍｍである。   The lid 1 and the container body 2 according to the present embodiment are formed by thermoforming a synthetic resin sheet by sheet molding such as vacuum molding, pressure molding, vacuum pressure molding, double-side vacuum molding, hot plate molding, and the like. May be. As the synthetic resin sheet, for example, a polyester resin such as polyethylene terephthalate, a styrene resin such as polystyrene, or an olefin resin such as polypropylene may be used. As the resin, for example, if a foamed resin is used, it is preferable because it is lightweight and has heat insulating properties. Furthermore, the front surface or the back surface of the sheet may be covered with a synthetic resin film, and when the surface is covered, printing may be performed. The thickness of the synthetic resin sheet is not particularly limited, but may be 0.15 to 0.5 mm, preferably 0.18 to 0.45 mm, and more preferably 0.2 to 0.35 mm.
