Description

本発明は、長尺状の収容物、特にブーケ状巻き寿司を見栄えよく配列できる包装用容器に関する。 TECHNICAL FIELD The present invention relates to a packaging container that can arrange elongated objects, particularly bouquet-shaped sushi rolls, in an attractive manner.

スーパーマーケット、コンビニエンスストアなどの小売店では、お惣菜、お寿司、フルーツ、野菜などの食料品がトレー状の容器に包装され、並べられているのがよく見かけられる。
従来では、容器は矩形箱状であり、収容物を単に収容するためのものであったが、最近では、消費者の購買意欲を惹起するため工夫が凝らされた容器が開発されている。
At retail stores such as supermarkets and convenience stores, it is common to see food items such as side dishes, sushi, fruits, and vegetables packaged in tray-like containers and displayed.
Conventionally, containers have been shaped like rectangular boxes and have been used to simply store items, but in recent years, containers have been developed that are designed to stimulate consumers' desire to purchase.

例えば、下記特許文献1には、底板と、この底板の長手方向に立設された一対の第1の側壁および短手方向に立設された一対の第2の側壁とが合成樹脂により一体成形されて上部に略長方形状の開口部が形成された果物収納容器において、第1の側壁に、開口部から底板に向けて漸次、第1の側壁間の中央側に傾斜するとともに、容器内部において凹曲面状をなす果物保持壁を形成したことを特徴とする果物収納容器が開示されている。この容器は、ぶどう等の果物を収納した場合に、搬送時の振動等に起因する果粒の果梗からの脱粒を抑え、見栄えがよくなるようにしたものである。 For example, in Patent Document 1 listed below, a bottom plate, a pair of first side walls erected in the longitudinal direction of the bottom plate, and a pair of second side walls erected in the lateral direction of the bottom plate are integrally molded from synthetic resin. In a fruit storage container in which a substantially rectangular opening is formed at the top of the container, the first side wall is gradually inclined from the opening toward the bottom plate toward the center between the first side walls, and inside the container. A fruit storage container is disclosed in which a fruit holding wall is formed in a concave shape. When this container stores fruits such as grapes, it suppresses the shedding of fruit from the stem due to vibrations during transportation, and improves the appearance.

また、下記特許文献2には、合成樹脂シートを熱成形した容器本体と蓋体とからなる食品包装用容器であって、容器本体が、底部と該底部の周囲に立設形成された外周部とからなり、底部には、平面部の上面側に膨出形成される食品を盛り付けるための第一突出部及び盛り付けた食品のズレを抑制する第二突出部とが形成され、第一突出部には、平面部から上昇傾斜する食品載置面が形成され、第二突出部が第一突出部と適度の間隔を開けた位置に形成されていることを特徴とする食品包装用容器が開示されている。この容器は、食品を収容した際に、食品を立てて盛り付けることにより、食品が沈み込んだ様に見えるのを防止して見栄えをよくすることができるものである。 Further, Patent Document 2 below discloses a food packaging container consisting of a container body and a lid made of a thermoformed synthetic resin sheet, in which the container body has a bottom and an outer circumference formed upright around the bottom. The bottom part is formed with a first protrusion part for plating the food which is bulged on the upper surface side of the plane part, and a second protrusion part for suppressing the displacement of the plated food, and the first protrusion part discloses a food packaging container characterized in that a food placement surface is formed that slopes upward from a flat surface, and a second protrusion is formed at a position with an appropriate distance from the first protrusion. has been done. When this container stores food, it can be arranged in an upright position to prevent the food from looking like it has sunk in, thereby improving its appearance.

手巻き寿司などの長尺状の食料品を容器に収容するには、単に横置きにして容器内に配列することなどが行われている。しかし、このような配列にすると包まれた具材が視認しにくくなり購買意欲を刺激する陳列とはいえなかった。
最近では、手巻き寿司をブーケ(逆円錐形)状に巻くこともあり、このようにすると、手持ちがしやすく、また、お花のブーケの如く見栄えのよいものである。
しかし、このようなブーケ状の巻き寿司を容器に収容すると、うまく容器内に収まらず隙間ができてしまい、まばらな感じを与え、購買意欲を減退させてしまうおそれがあった。また、ブーケ状の巻き寿司は、横置きにしてしまうとせっかくの見栄えが活かされず、購買意欲を刺激できないおそれもあった。
In order to store long food items such as hand-rolled sushi in a container, they are simply placed horizontally and arranged in the container. However, with this arrangement, the wrapped ingredients were difficult to see, and the display could not stimulate the desire to purchase.
Recently, hand-rolled sushi is sometimes rolled into a bouquet (inverted cone shape), which makes it easier to hold in the hand and also looks nice, like a bouquet of flowers.
However, when such bouquet-shaped sushi rolls are placed in a container, they do not fit neatly into the container, leaving gaps, giving the sushi a sparse feel, which may reduce the desire to purchase the sushi. In addition, if the bouquet-shaped sushi rolls were placed horizontally, the beauty of the sushi rolls would not be utilized, and there was a risk that the sushi rolls would not be able to stimulate the desire to purchase.

そこで、本発明の目的は、長尺状の収容物、特にブーケ状の巻き寿司を見栄えよく収容することができる包装用容器を提供することにある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging container that can accommodate long items, particularly bouquet-shaped sushi rolls, with good appearance.

本発明の包装用容器の一形態は、長尺状収容物用の包装用容器であって、容器本体に、底面部と、該底面部の周縁部から立ち上がる周壁部と、該周壁部の上端部で囲まれた開口部とを備え、該底面部の中央付近に、環状に***させ、その内側に前記長尺状収容物の下端が納まる環状突条部を備え、前記周壁部容器内側又は容器外側に向かい膨らませて凸形状又は凹形状に成形した、前記長尺状収容物が引っ掛かる周壁膨出部を備えたことを特徴とする。 One embodiment of the packaging container of the present invention is a packaging container for a long object, which includes a container body including a bottom portion, a peripheral wall portion rising from a peripheral edge of the bottom portion, and an upper end of the peripheral wall portion. An annular protrusion is provided near the center of the bottom surface, and an annular protrusion is provided inside of which the lower end of the elongated object is accommodated, and the peripheral wall is provided with an annular protrusion surrounded by an inner side of the container. Alternatively, the container may include a peripheral wall bulge portion that is inflated toward the outside of the container to have a convex or concave shape, and on which the elongated stored object is caught.

上記形態の包装用容器は、例えば、長尺状収容物の一端側(下端側)を納まり凹部に納めつつ、長尺状収容物を開口部付近に立てかけるようにして配列することにより、縦置きにして配列可能であり、複数の長尺状収容物を花束の如く収容できる。そのため、購買者の目に留まりやすくなり、購買意欲を刺激することができる。 The packaging container of the above form can be placed vertically by, for example, placing one end (lower end side) of the long stored items in the recess and arranging the long stored items so as to lean them up near the opening. It is possible to arrange a plurality of elongated objects like a bouquet of flowers. Therefore, it can easily catch the attention of buyers and stimulate their desire to purchase.

上記形態の包装用容器において、周壁部の上端部付近に、上方に向かい容器外側に拡開する段状の段差部を備えることが好ましい。段差部を備えることにより、容器を大きく見せつつ、収容した長尺状収容物が容器の中央付近に集まってボリューム感があるように演出することができる。 In the packaging container of the above embodiment, it is preferable that the peripheral wall portion has a stepped portion near the upper end that extends upward and outward from the container. By providing the stepped portion, it is possible to make the container look larger and to create a sense of volume as the elongated stored items gather near the center of the container.

上記形態の包装用容器において、周壁部に、周方向に所定間隔で容器内側又は容器外側に向かい膨らませた周壁膨出部を備えることが好ましい。周壁膨出部を備えることにより、これを目印として収容物を配列しやすくなり、また、立てかけた収容物が引っ掛かり倒れることを防止できる。 In the packaging container of the above embodiment, it is preferable that the peripheral wall portion include peripheral wall bulges that are inflated toward the inside of the container or the outside of the container at predetermined intervals in the circumferential direction. By providing the peripheral wall bulge, it becomes easier to arrange the stored items using this as a mark, and it is possible to prevent the stored items that are propped up from getting caught and falling down.

上記形態の包装用容器において、容器本体に嵌合可能な蓋体を備え、周壁部の上端部に、容器外側に張り出す本体フランジ部を備え、蓋体に、本体フランジ部よりも幅狭で、容器本体に嵌合させた状態で、本体フランジ部の容器外側寄りに載る蓋体フランジ部を備えることが好ましい。蓋体フランジ部を本体フランジ部よりも外側にずれた位置に配することにより、蓋体を容器本体に被せる際に、収容物自体や収容物の包装などの噛み込みを防止することができる。 The packaging container of the above configuration includes a lid that can be fitted to the container main body, a main body flange portion extending to the outside of the container at the upper end of the peripheral wall portion, and a lid body having a width narrower than the main body flange portion. It is preferable to include a lid flange portion that rests on the outer side of the container on the main body flange portion when fitted to the container main body. By arranging the lid flange at a position shifted outward from the main body flange, it is possible to prevent the contents themselves or the packaging of the contents from getting caught when the lid is placed over the container body.

蓋体を備えた場合には、蓋体をドーム状にすることが好ましい。ドーム状にすることにより四方からの視認性を確保し、立体感のある包装にすることができる。 When a lid is provided, it is preferable that the lid be dome-shaped. The dome shape ensures visibility from all sides and allows packaging to have a three-dimensional feel.

上記形態の包装用容器は、筆記具などの文房具、花束、野菜スティックなどの長尺状収容物を収容することができ、特にブーケ状巻き寿司やコーン付きアイスクリームなどの逆円錐形状収容物を収容するのに適したものである。 The above-mentioned packaging container can accommodate elongated items such as stationery such as writing instruments, bouquets of flowers, and vegetable sticks, and in particular can accommodate inverted cone-shaped items such as bouquet-shaped sushi rolls and ice cream with cones. suitable for doing so.

以下、本発明の包装用容器の一実施形態を、図面に基づいて説明する。 Hereinafter, one embodiment of the packaging container of the present invention will be described based on the drawings.

本発明の一実施形態の包装用容器1は、図1に示すように、容器本体2と蓋体3とを備える。
本実施形態では蓋体3を備えるが、容器本体2のみで蓋体3を備えない包装用容器1としてもよい。
包装用容器1は、例えば、総菜、サラダ、お寿司などの食料品などを収容物として収容することができ、エビ天ぷら、スティックサラダ、巻き寿司などの長尺状の収容物を収容するのが好ましく、特に、ブーケ状の巻き寿司、コーン付きアイスクリームなど下端部が先細りとなった逆三角錐形状の収容物を収容するのが好ましい。食料品以外にも、筆記具などの文房具、花束などを収容してもよい。
A packaging container 1 according to an embodiment of the present invention includes a container body 2 and a lid 3, as shown in FIG.
In this embodiment, the lid 3 is provided, but the packaging container 1 may be provided with only the container body 2 and without the lid 3.
The packaging container 1 can store, for example, foodstuffs such as prepared dishes, salads, and sushi. Preferably, it is particularly preferable to accommodate an inverted triangular pyramid-shaped container with a tapered lower end, such as a bouquet of sushi rolls or ice cream with a cone. In addition to food items, stationery such as writing instruments, bouquets of flowers, etc. may also be stored.

容器本体2及び蓋体3は、特に限定するものではないが、合成樹脂シートを熱成形して製造することができる。合成樹脂シートは、非発砲樹脂シート、発泡樹脂シートのいずれでもよい。
非発砲樹脂シートの場合には、厚みが0.1mm~3mmの範囲内、特に0.3mm~2mmの範囲内のシートを用いるのが好ましく、発砲樹脂シートの場合には、厚みが0.5mm~4mmの範囲内、特に1mm~3mmの範囲内のシートを用いるのが好ましい。また、発泡樹脂シートの場合には、発泡倍率を1.01倍~20倍、特に1.05倍~10倍にするのが好ましい。
容器本体2を発泡樹脂シート、蓋体3を非発泡樹脂シートから形成するなど両者が相違してもよい。
Although the container body 2 and the lid 3 are not particularly limited, they can be manufactured by thermoforming a synthetic resin sheet. The synthetic resin sheet may be either a non-foamed resin sheet or a foamed resin sheet.
In the case of a non-foamed resin sheet, it is preferable to use a sheet with a thickness in the range of 0.1 mm to 3 mm, particularly in the range of 0.3 mm to 2 mm, and in the case of a foamed resin sheet, the thickness is 0.5 mm. It is preferable to use a sheet with a thickness in the range of 1 to 4 mm, particularly 1 to 3 mm. In the case of a foamed resin sheet, the expansion ratio is preferably 1.01 times to 20 times, particularly 1.05 times to 10 times.
The container body 2 may be formed from a foamed resin sheet, and the lid 3 may be formed from a non-foamed resin sheet.

非発泡樹脂シートとしては、例えば、ポリエチレン系樹脂シート・ポリプロピレン系樹脂シートなどのポリオレフィン系樹脂シート、ポリスチレン系樹脂シート、ポリエチレンテレフタレート系樹脂シート・耐熱性を付与した変性ポリエチレンテレフタレート系樹脂シートなどのポリエステル系樹脂シートなどの熱可塑性樹脂シートを用いることができる。また、電子レンジの加熱に耐え得るもの、例えば、耐熱性ポリスチレン系樹脂シート、ポリプロピレン系樹脂シート、耐熱性を付与した変性ポリエチレンテレフタレート系樹脂シートを用いてもよい。 Examples of non-foamed resin sheets include polyolefin resin sheets such as polyethylene resin sheets and polypropylene resin sheets, polyester sheets such as polystyrene resin sheets, polyethylene terephthalate resin sheets, and heat-resistant modified polyethylene terephthalate resin sheets. A thermoplastic resin sheet such as a thermoplastic resin sheet can be used. Further, materials that can withstand heating in a microwave oven, such as a heat-resistant polystyrene resin sheet, a polypropylene resin sheet, or a modified polyethylene terephthalate resin sheet imparted with heat resistance, may be used.

発泡樹脂シートとしては、例えば、発泡ポリオレフィン系樹脂シート、発泡ポリスチレン系樹脂シート、発泡ポリエチレンテレフタレートなどの発泡ポリエステル系樹脂シートを用いることができる。
合成樹脂シートを積層した積層シートを用いることもでき、積層シートとしては、例えば、非発泡樹脂シート又は発泡樹脂シートに樹脂フィルムを熱ラミネートした積層シート、共押出法による積層シート、押出ラミネート法による積層シートなどを挙げることができる。なかでも、発泡樹脂シートの片面又は両面に樹脂フィルムをラミネートした積層シートを用いるのが好ましく、この際の樹脂フィルムの厚みは5μm~200μm、特に10μm~100μmが好ましい。
As the foamed resin sheet, for example, a foamed polyester resin sheet such as a foamed polyolefin resin sheet, a foamed polystyrene resin sheet, and a foamed polyethylene terephthalate resin sheet can be used.
A laminated sheet made by laminating synthetic resin sheets can also be used, and examples of the laminated sheet include a laminated sheet made by thermally laminating a resin film on a non-foamed resin sheet or a foamed resin sheet, a laminated sheet made by a coextrusion method, and a laminated sheet made by an extrusion lamination method. Examples include laminated sheets. Among these, it is preferable to use a laminated sheet in which a resin film is laminated on one or both sides of a foamed resin sheet, and the thickness of the resin film in this case is preferably 5 μm to 200 μm, particularly preferably 10 μm to 100 μm.

熱成形としては、真空成形、圧空成形、真空圧空成形、熱板成形などを挙げることができる。
容器本体2及び蓋体3は、黒色や白色などの有色でもよいが、内部が視認できるように透明乃至半透明であることが好ましいが、蓋体3を透明、容器本体2を白色にするなど両者が相違してもよい。容器本体2及び蓋体3が透明であれば、立体的盛り付けた収容物全体が視認され、購買意欲を高めることができる。また、容器本体2及び蓋体3の表面に、文字、絵柄などの印刷を施してもよい。
Examples of thermoforming include vacuum forming, pressure forming, vacuum pressure forming, hot plate forming, and the like.
The container body 2 and the lid 3 may be colored such as black or white, but are preferably transparent or semi-transparent so that the inside can be visually recognized. Both may be different. If the container main body 2 and the lid 3 are transparent, the entire three-dimensionally arranged contents can be visually recognized, thereby increasing the desire to purchase. Further, the surfaces of the container body 2 and the lid 3 may be printed with characters, pictures, etc.

容器本体2は、図1,図2又は図4に示すように、逆円錐台状としてあり、底面部21の周縁部から周壁部22を立ち上げて形成し、周壁部22の上端部に囲まれた部分を、収容物を容器本体2内に収容する開口部23としてある。
本実施形態では、容器本体2を逆円錐台状としてあるが、これに限定されるものではなく、直方体状、逆四角錐台状、逆多角錐台状、逆楕円錐台状などの形状にしてもよい。
容器本体2を逆円錐台状とした場合には、図4に示すように、底面部21の外径(B)と開口部23の開口径(D)との比(D/B)が約1.3~3.8の範囲内、特に約1.5~3の範囲内にするのが好ましい。1.3未満であると収容物を盛り付けた際に単調な見栄えとなるおそれがあり、3.8を超えると容器本体2が安定せず転倒するおそれがある。
As shown in FIG. 1, FIG. 2, or FIG. 4, the container body 2 has an inverted truncated cone shape, and is formed by raising a peripheral wall 22 from the peripheral edge of a bottom surface 21, and is surrounded by the upper end of the peripheral wall 22. The closed portion serves as an opening 23 for accommodating the contents into the container body 2.
In this embodiment, the container main body 2 is shaped like an inverted truncated cone, but it is not limited to this, and may have a shape such as a rectangular parallelepiped, an inverted square truncated pyramid, an inverted polygonal truncated pyramid, or an inverted elliptical truncated cone. You can.
When the container body 2 is shaped like an inverted truncated cone, the ratio (D/B) of the outer diameter (B) of the bottom portion 21 and the opening diameter (D) of the opening 23 is approximately It is preferably within the range of 1.3 to 3.8, particularly approximately 1.5 to 3. If it is less than 1.3, there is a risk that the appearance will be monotonous when the contents are arranged, and if it exceeds 3.8, there is a risk that the container body 2 will not be stable and will fall.

底面部21は、図2に示すように、平面視円形平面状に形成してあり、中央付近に環状に膨らませた環状突条部24が設けてある。環状突条部24は、平面視において、円形環状に形成してあり、環状突条部24に囲われた内部を収容物の一端部が納まる納まり凹部24aとしてある。環状突条部24は、図4又は図5に示すように、断面視台形状としてあり、特に限定するものではないが、高さを5mm~20mmの範囲内、特に8mm~15mmの範囲内にするのが好ましい。納まり凹部24aの底面の面積は、特に限定するものではないが、1cm~9cmの範囲内、特に2cm~6cmの範囲内が好ましい。
底面部21と納まり凹部24aの底面の高さは、本実施形態では同じにしてあるが相違してもよく、例えば、図4に示すように、底面部21からの環状突条部24の高さをHb、納まり凹部24aの底面からの環状突条部24の高さをHcとした場合、Hc/Hbが0.1~1.0の範囲内となるようにするのが好ましい。0.1未満であると収容物が立て掛けずらくなり、1.0を超えると容器本体2が安定しなくなる。
また、本実施形態では環状突条部24を円形環状にしてあるが、矩形環状、六角形・八角形などの多角形環状、楕円形環状などにしてもよく、環状形状としてあればよい。
As shown in FIG. 2, the bottom portion 21 is formed into a circular planar shape when viewed from above, and is provided with an annular protruding portion 24 near the center. The annular protruding portion 24 is formed into a circular ring shape in a plan view, and the interior surrounded by the annular protruding portion 24 is a recessed portion 24a in which one end of the stored object is accommodated. As shown in FIG. 4 or FIG. 5, the annular protruding portion 24 has a trapezoidal cross-sectional shape, and has a height within a range of 5 mm to 20 mm, particularly within a range of 8 mm to 15 mm, although it is not particularly limited. It is preferable to do so. The area of the bottom surface of the fitting recess 24a is not particularly limited, but is preferably within the range of 1 cm 2 to 9 cm 2 , particularly within the range of 2 cm 2 to 6 cm 2 .
Although the heights of the bottom surface of the bottom surface part 21 and the bottom surface of the fitting recess 24a are the same in this embodiment, they may be different. For example, as shown in FIG. Assuming that the height is Hb and the height of the annular protrusion 24 from the bottom of the fitting recess 24a is Hc, it is preferable that Hc/Hb be within the range of 0.1 to 1.0. If it is less than 0.1, it becomes difficult to stand up the stored items, and if it exceeds 1.0, the container body 2 becomes unstable.
Further, in this embodiment, the annular protruding portion 24 is formed into a circular ring shape, but it may be formed into a rectangular ring shape, a polygonal ring shape such as a hexagonal or octagonal shape, an elliptical ring shape, or any other ring shape.

周壁部22は、図4又は図5に示すように、底面部21の周縁部から上方に拡開するように所定高さに形成してある。
容器本体2を逆円錐台状とした場合には、図4に示すように、周壁部22の高さ(H)と開口部23の開口径(D)との比(H/D)が、約0.6~1の範囲内にするのが好ましい。0.6未満であると収容物を盛り付けた際に単調な見栄えとなるおそれがあり、1を超えると容器本体2の成型しにくくなるおそれがある。
周壁部22の上端部付近には、図4又は図5に示すように、上方に向かい容器外側に拡がる段状の段差部25が設けてある。段差部25を設けることにより、容器1を大きく見せつつ、収容物が中央付近に寄り集まってボリュームがあるように演出することができる。本実施形態では、段差部25を下側の第一段差部25aと上側の第二段差部25bを備えた二段構造としてあるが、段差部25は少なくとも一段としてあればよく、三段、四段構造などの複数段構造にしてもよい。
As shown in FIG. 4 or 5, the peripheral wall portion 22 is formed at a predetermined height so as to expand upward from the peripheral edge of the bottom surface portion 21.
When the container body 2 is shaped like an inverted truncated cone, the ratio (H/D) of the height (H) of the peripheral wall 22 and the opening diameter (D) of the opening 23 is Preferably, it is within the range of about 0.6-1. If it is less than 0.6, it may result in a monotonous appearance when the contents are arranged, and if it exceeds 1, it may be difficult to mold the container body 2.
As shown in FIG. 4 or 5, near the upper end of the peripheral wall portion 22, a stepped portion 25 is provided that extends upward and toward the outside of the container. By providing the stepped portion 25, the container 1 can be made to look larger, and the contents can be gathered near the center to create the illusion of volume. In this embodiment, the step portion 25 has a two-step structure including a first step portion 25a on the lower side and a second step portion 25b on the upper side, but the step portion 25 may have at least one step, three steps, four steps, etc. A multi-stage structure such as a stage structure may be used.

周壁部22には、図5に示すように、容器本体2の高さ中間付近を容器内側に突き出すように膨出させた周壁膨出部26が形成してある。周壁膨出部26は、周方向に所定の間隔で複数配列してある。より具体的には、周壁膨出部26は、底面部21付近から高さ方向に沿い徐々に容器内側に膨らませ、図1に示すように、側面視において周壁部22の高さ中間付近を底辺とした逆二等辺三角形状を呈するように凹ませて形成してある。周壁膨出部26を設けることにより、これを目印として収容物を周方向に所定間隔で配列しやすくなる。また、立てかけた収容物が引っ掛かり転倒することを防止することができる。このような観点から、各周壁膨出部26の配列は、容器本体2の平面視において、点対象となる位置に配置することが好ましい。このようにすることにより、収容物の盛り付けが均等になり見栄えがよく、購買意欲を向上させることができる。周壁膨出部26は容器外側に膨らませて形成してもよいが、収容物の転倒防止の観点から容器内側に膨らませるのが好ましい。
周壁膨出部26は、これら形状に限定されるものではなく、容器内側又は外側に膨出させた適宜形状を採用することができる。
As shown in FIG. 5, the peripheral wall portion 22 is formed with a peripheral wall bulging portion 26 that bulges near the middle of the height of the container body 2 so as to protrude inside the container. A plurality of peripheral wall bulges 26 are arranged at predetermined intervals in the circumferential direction. More specifically, the peripheral wall bulging portion 26 gradually bulges inward from the vicinity of the bottom surface portion 21 along the height direction, and as shown in FIG. It is recessed to form an inverted isosceles triangular shape. By providing the peripheral wall bulging portion 26, it becomes easier to arrange the stored items at predetermined intervals in the circumferential direction using this as a mark. Moreover, it is possible to prevent the stored items that are propped up from getting caught and falling over. From this point of view, it is preferable that the peripheral wall bulges 26 are arranged in point-symmetrical positions when the container body 2 is viewed from above. By doing so, the contents are arranged evenly, giving a good appearance and increasing the desire to purchase. Although the peripheral wall bulging portion 26 may be formed by expanding outward from the container, it is preferably formed by expanding toward the inside of the container from the viewpoint of preventing the contents from falling over.

The packaging container 1 can be used by accommodating an object and fitting the lid 3 thereto. As an example, as shown in FIG. 7, a case will be described in which a bouquet-shaped sushi roll 4 is stored as a long stored object.
The lower end of the sushi roll 4 is placed in the recess 24a while the side surface on the upper end side is placed near the opening 23, and the sushi roll 4 is placed in the container body 2. At this time, it is preferable to arrange the sushi rolls 4 between the peripheral wall bulges 26. Next, other rolled sushi rolls 4 are placed in the container main body 2 and arranged in a similar manner between adjacent peripheral wall bulges 26 with their lower ends stored in the recesses 24a. In this way, by arranging a plurality of sushi rolls 4 in the circumferential direction within the container body 2, the sushi rolls 4 can be arranged like a bouquet of flowers to improve the appearance.

容器本体2に蓋3を被せるには、蓋3を容器本体2の上方から押込み、図6に示すように、嵌合凹部28aに嵌合凸部33aを嵌め合わせて嵌合させればよい。
この際、蓋体フランジ部32を、本体フランジ部27よりも幅狭に形成し、本体フランジ部27の容器外側寄りに載るようにしておけば、嵌合の際に巻き寿司4自体や巻き寿司4の包装などの噛み込みを防止することができる。
In order to cover the container body 2 with the lid 3, the lid 3 is pushed in from above the container body 2, and as shown in FIG. 6, the fitting protrusion 33a is fitted into the fitting recess 28a.
At this time, if the lid flange part 32 is formed narrower than the main body flange part 27 and placed on the outer side of the container of the main body flange part 27, the sushi roll 4 itself and the sushi roll can be It is possible to prevent packaging etc. from getting caught in item 4.
