Description

本発明は、蓋体を容器本体に嵌合する際に、嵌合部への収容物の侵入を防ぐことができる包装用容器に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container capable of preventing contents from entering a fitting portion when fitting a lid body to a container body.

薄肉樹脂シート製容器が普及しており、例えば、小売店においては弁当や総菜などの食料品を包装するのに用いられている。
このような容器は、蓋体を容器本体に嵌め合わせ、容器本体の開口部を覆い、ほこりなどが収容物に付着するのを防ぐともに内部の収容物が漏出しないように密封できるものが多い。
Thin-walled resin sheet containers are widespread, and are used, for example, in retail stores to package food products such as lunch boxes and side dishes.
Many of such containers can be sealed by fitting the lid to the container body to cover the opening of the container body to prevent dust from adhering to the contents and also to prevent leakage of the contents inside.

薄肉樹脂シート製容器における蓋体と容器本体との嵌合構造としては様々な構造があるが、外嵌合構造、内嵌合構造、内外嵌合構造などが一般的に知られている。このなかでも、内嵌合構造又は内外嵌合構造は、嵌合部が密着して嵌合力があるため、蓋体が外れにくく密閉性に優れており、比較的長時間に渡り陳列する総菜などの容器に多く採用されている。 There are various structures for fitting the lid body and the container body in a container made of a thin resin sheet, and generally known structures include an outer fitting structure, an inner fitting structure, and an inner/outer fitting structure. Among these, the inner fitting structure or the inner and outer fitting structure has a fitting force due to close contact of the fitting portion, so that the lid is difficult to come off and has excellent sealing performance. are widely used in containers.

内嵌合構造又は内外嵌合構造の容器は、嵌合する際に、はみ出した収容物を嵌合部に挟み込んでしまったまま嵌合してしまうことがある。そのようなときには嵌合部が密着するため収容物を押し潰してしまい、陳列した際や開封した際に、それが目に付き、印象がよくなく、食欲を減衰させてしまうことがあった。 When a container having an inner fitting structure or an inner/outer fitting structure is fitted, it may be fitted with the protruding contents sandwiched between the fitting portions. In such a case, since the fitting portion is in close contact with the contents, the contents are crushed, and when the contents are displayed or opened, the contents are conspicuous, giving an unfavorable impression and reducing appetite.

そのような課題に対して、例えば、下記特許文献1に示されるように、『側壁の上部に嵌合突条を周設した容器本体と、前記嵌合突条に嵌合される嵌合凹条を周設した蓋体とからなる内外嵌合型の包装用容器であって、前記容器本体の底面から前記嵌合突条に至る前記側壁に、前記蓋体側の当接平面が当接することになる当該容器本体側の当接平面の一部を残しながら、前記蓋体側の当接平面の当接を回避する傾斜面を形成したことを特徴とする内外嵌合型の包装用容器』が開発され、密閉性を確保しながら、収納物の噛み込みをも防止することが行われている。 In order to solve such a problem, for example, as shown in Patent Document 1 below, "a container body in which a fitting ridge is provided around the upper part of the side wall and a fitting recess to be fitted to the fitting ridge" is proposed. An inner-outer fitting type packaging container comprising a lid having a ridge around it, wherein a contact plane on the side of the lid abuts against the side wall extending from the bottom surface of the container body to the fitting ridge. An inner-outer fitting type packaging container characterized by forming an inclined surface that avoids contact with the contact plane on the lid side while leaving a part of the contact plane on the container body side. It has been developed to ensure airtightness while also preventing the contents from getting caught.

特開2007-176507号公報JP 2007-176507 A

上記特許文献1の容器は、収容物の噛み込みを防止できるようにしてあるが、小売店などで販売する総菜などは、大量に迅速に生産しなければならない。そのため、総菜などを容器に収容する工程において、嵌合部への侵入は一定の割合では生じてしまうものであった。特に、内嵌合構造や内外嵌合構造の容器は、蓋体の外縁付近に嵌合部が立ち上がるように設けてあるため、この付近にある収容物が見えにくく、嵌合部への収容物の侵入が発生しやすいものであった。 Although the container of Patent Document 1 is designed to prevent contents from being caught in the container, delicatessen sold at retail stores and the like must be produced quickly in large quantities. Therefore, in the process of storing delicatessen in the container, the penetration into the fitting portion occurs at a certain rate. In particular, containers with an inner fitting structure or an inner and outer fitting structure are provided so that the fitting part rises near the outer edge of the lid, so that it is difficult to see the contents in the vicinity, and the contents in the fitting part are difficult to see. Intrusion of

そこで、本発明の目的は、密閉性を確保しながら、嵌合部への収容物の侵入の発生を防ぐことができるようにした包装用容器を提供することにある。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a packaging container capable of preventing the contents from entering the fitting portion while ensuring airtightness.

本発明の一形態の包装用容器は、容器本体と、それに嵌合させて開口部を被覆する透明な蓋体とを備えた包装用容器であって、該容器本体には、外縁付近に、上向きに突出する嵌合部を本体全周に設け、該嵌合部に対して容器本体内側の位置に、水平面状の上縁面部を備え、該蓋体には、側壁面部の下端部から外向きに水平状に張り出す鍔部を設け、該鍔部の外縁付近に、上向きに突出して該嵌合部と嵌合する被嵌合部を備え、該被嵌合部に対して蓋体内側に位置し、該容器本体に該蓋体を嵌合させた際に、該上縁面部の容器本体内側の縁部の上方付近に配される、上向きに膨出する凸条部を蓋体全周に又は蓋体周方向に間隔を開けて設けたことを特徴とする。 A packaging container according to one aspect of the present invention is a packaging container comprising a container body and a transparent lid body fitted to the container body to cover an opening, wherein the container body includes, near the outer edge, A fitting portion protruding upward is provided on the entire periphery of the main body, and a horizontal upper edge surface portion is provided at a position inside the container body with respect to the fitting portion. Provided with a flange extending horizontally in a direction, provided with a fitted portion projecting upward near the outer edge of the flange to be fitted with the fitted portion, and extending to the inside of the lid with respect to the fitted portion , and when the lid is fitted to the container body, the upwardly bulging ridge portion disposed near the upper edge of the inner edge of the container body of the upper edge surface portion is attached to the entire lid. It is characterized in that they are provided at intervals around the circumference or in the circumferential direction of the lid.

上記形態の包装用容器は、蓋体を容器本体に嵌合する際に、収容物が容器本体内を揺れ動いたとしても周壁面部沿いに移動し、上縁面部の縁部から上方に舞い上がって凸条部内へ収容物が入り込み、凸条部により堰き止められるため、嵌合部及び被嵌合部へ収容物が侵入することを防ぎ、噛み込みが発生しにくくなる。凸条部を蓋体全周に設ければ、凸条部に収まった収容物が周方向へと分散でき、より嵌合部への侵入の発生を防ぐことができる。このような観点から、流動性のある収容物、例えば、ポテトサラダ、汁物などに対して効果を発揮することができる。 In the packaging container of the above configuration, when the lid body is fitted to the container body, even if the contents sway within the container body, they move along the peripheral wall surface and rise upward from the edge of the upper edge surface. Since the stored object enters the protruding portion and is dammed by the protruding portion, the stored object is prevented from entering the fitting portion and the fitted portion, and is less likely to be caught. By providing the protruding portion around the entire periphery of the lid, the stored items contained in the protruding portion can be dispersed in the circumferential direction, and the occurrence of intrusion into the fitting portion can be further prevented. From this point of view, it is effective for fluid storage items such as potato salad and soup.

さらには、蓋体が透明であるため、蓋体を嵌合する際に収容物の配置を確認しやすく、また、凸条部を蓋体の全周に渡って設け、凸条部が容器本体の上縁面部の縁部上方に位置するため、凸条部から外側にはみ出した収容物があることを認識しやすく、収容物の噛み込みを防ぐことができる。凸条部を上向きに膨出させ、それを容器本体の上縁面部の縁部上方に配したため、凸条部により隙間ができ、蓋体の鍔部と上縁面部との間における挟持力が弱まり、収容物が挟まれにくくなる。 Furthermore, since the lid is transparent, it is easy to check the arrangement of the contents when fitting the lid. Since it is positioned above the edge of the upper edge surface of the housing, it is easy to recognize that there is a contained object protruding outside the ridge, and it is possible to prevent the contained object from being caught. Since the ridge portion is bulged upward and arranged above the edge of the upper edge surface portion of the container body, a gap is formed by the ridge portion, and the clamping force between the collar portion and the upper edge surface portion of the lid body is reduced. It weakens, making it difficult for the contents to get caught.

上記形態の包装用容器は、前記容器本体に前記蓋体を嵌合させた際に、前記鍔部と前記上縁面部とが接しないようすることが好ましい。
このようにすることにより、鍔部と上縁面部との間に隙間ができ、この間に収容物が挟み込まれにくくなる。
In the packaging container having the above configuration, it is preferable that the flange portion and the upper edge surface portion do not come into contact with each other when the lid body is fitted to the container body.
By doing so, a gap is formed between the flange portion and the upper edge surface portion, making it difficult for the stored items to be caught in the gap.

上記形態の包装用容器は、前記被嵌合部の高さを前記凸条部の高さよりも高くするのが好ましい。
このようにすることにより、容器を小売店などで陳列した際には、凸条部が被嵌合部に遮られて視認されにくくなり、容器の外観印象を良好にすることができる。
In the packaging container having the above configuration, it is preferable that the height of the fitted portion is higher than the height of the ridge portion.
By doing so, when the container is displayed at a retail store or the like, the convex portion is blocked by the fitted portion and becomes difficult to be visually recognized, and the external impression of the container can be improved.

上記形態の包装用容器は、前記凸条部を断面三角形状とするのが好ましく、この場合、前記蓋体の前記側壁面部を傾斜面状とし、その傾斜角度を前記凸条部の傾斜角度とは相違させるのが好ましい。
このようにすることにより、購買者が容器の内部を確認するために側壁面部を覗くと、凸条部の傾斜角度が異なるため反射などにより凸条部付近の内部が視認されにくくなり、この付近の内部を隠すことができ、購買者が収容物に注視するようにすることができる。
In the packaging container having the above configuration, it is preferable that the ridge portion has a triangular cross-section. are preferably different.
By doing so, when a purchaser looks into the side wall surface to check the inside of the container, it is difficult to see the inside near the ridges due to reflection due to the different inclination angles of the ridges. can be hidden, allowing the purchaser to keep an eye on the contents.

底面部21は、図1又は図3に示すように、収容物を載せることができる平面視長方形水平面状の載置面21bを備え、その周囲に、一定幅で凹ませ、平面視ロの字状を呈する脚部21aを形成してある。脚部21aは、載置面21bに食料品などを載せた場合には、それから滲出する水分などを貯める貯留部も兼ねることができる。また、脚部21aの一部(載置面21b長辺側の中間付近)は、***させた台状部21cとしてあり、その上面には並行状に配した複数の突条部を備える。 As shown in FIG. 1 or FIG. 3, the bottom part 21 has a mounting surface 21b which is rectangular in plan view and horizontal on which a content can be placed. A shaped leg portion 21a is formed. When a food product or the like is placed on the mounting surface 21b, the leg portion 21a can also serve as a storage portion for storing moisture or the like exuded from the food product. A portion of the leg portion 21a (near the middle of the long side of the mounting surface 21b) is formed as a raised pedestal portion 21c, and the upper surface thereof is provided with a plurality of ridges arranged in parallel.

載置面21bには、突部21dを配してあり、突部21dは平面視において凸レンズ形状を呈するように形成してある。

It is designed to have a rectangular shape.
A flange portion 23 is provided on the upper edge portion of the peripheral wall portion 22 and protrudes in a horizontal plane to the outside of the container body.

周壁面部22に、又は周壁面部22から脚部21aの底面にかけて、高さ方向に延びるリブ部22aが複数並行状に設けてあり、容器本体2を補強するようにしてある。リブ部22aは、容器本体内側に向かい三角形状に突出するように形成してあるが、リブ部22aの形状はこれに限定されるものではない。 A plurality of rib portions 22a extending in the height direction are provided in parallel on the peripheral wall portion 22 or from the peripheral wall portion 22 to the bottom surface of the leg portion 21a to reinforce the container body 2. As shown in FIG. The rib portion 22a is formed to protrude in a triangular shape toward the inside of the container body, but the shape of the rib portion 22a is not limited to this.

嵌合部24は、図5に示すように、鍔部23の外縁付近を上向きに突出させて下方が開口する断面コの字状としてある。嵌合部24の上側をテーパ状、下側を逆テーパ状とし、後述する被嵌合部34を嵌合できるようにしてある。本実施形態では、嵌合部24及び被嵌合部34を容器本体内側及び外側が係止する内外嵌合構造としてあるが、内側のみが係止する内嵌合構造としてもよい。 As shown in FIG. 5, the fitting portion 24 has a U-shaped cross-section that protrudes upward near the outer edge of the collar portion 23 and is open at the bottom. The upper side of the fitting portion 24 is tapered, and the lower side thereof is tapered inversely so that a fitted portion 34, which will be described later, can be fitted. In the present embodiment, the fitting part 24 and the fitted part 34 have an inside-outside fitting structure in which the inside and outside of the container body are locked, but an inside-fitting structure in which only the inside is locked may be used.

鍔部23には、嵌合部24よりも容器本体内側に、水平面状の上縁面部25を設けてある。また、図3に示すように、容器本体2の四隅部付近の鍔部23を容器本体外側に延ばした平面視三角形状の摘み部26を設けてある。 The brim portion 23 is provided with a horizontal upper edge surface portion 25 inside the container body with respect to the fitting portion 24 . Further, as shown in FIG. 3, the flanges 23 near the four corners of the container body 2 are provided with knobs 26 that are triangular in plan view and extend outward from the container body.

蓋体3は、図1、図2又は図4に示すように、薄型の台形台状に形成してあり、天面部31と、天面部31の周縁から下方に向かう側壁面部32と、側壁面部32の下縁部から蓋体外側に張り出す鍔部33と、鍔部33の外縁付近に設けた、嵌合部24に嵌合する被嵌合部34と、を備える。 As shown in FIG. 1, FIG. 2, or FIG. 4, the lid 3 is formed in a thin trapezoidal trapezoidal shape, and includes a top surface portion 31, a side wall portion 32 extending downward from the peripheral edge of the top surface portion 31, and a side wall portion. A flange portion 33 that protrudes from the lower edge portion of 32 to the outside of the lid body, and a fitted portion 34 that is provided near the outer edge of the flange portion 33 and is fitted to the fitting portion 24 .

天面部31は、平面視丸隅長方形状の水平面状にしてある。
側壁面部32は、天面部31の周縁から下方に向かい垂下乃至傾斜する面としてあり、本実施形態では、図5に示すように、上側と下側とで角度の変わる傾斜面としてあり、上側が急斜面、下側が緩斜面になる傾斜角度に形成してある。
側壁面部32には、蓋体3の四隅付近に、隅部に対して両側に、蓋体内側に向けて凹陥させた凹陥部32aが形成してある。
The top surface portion 31 is formed in a horizontal plane shape of a rectangular shape with rounded corners in a plan view.
The side wall surface portion 32 is a surface that hangs or slopes downward from the peripheral edge of the top surface portion 31. In this embodiment, as shown in FIG. It is formed at an angle of inclination with a steep slope and a gentle slope on the lower side.
The side wall surface portion 32 is formed with recessed portions 32a recessed toward the inside of the lid body near the four corners of the lid body 3 on both sides of the corners.

鍔部33は、蓋体外側に水平面状に張り出すように形成してある。
被嵌合部34は、図5に示すように、鍔部33の外縁付近を上向きに突出させて下方が開口する断面コの字状として形成してあり、上側をテーパ状、下側を逆テーパ状として嵌合部24に内外嵌合できるようにしてある。
The flange portion 33 is formed so as to protrude in a horizontal plane from the outside of the lid.
As shown in FIG. 5, the fitted portion 34 is formed so that the vicinity of the outer edge of the collar portion 33 protrudes upward and has a U-shaped cross-section with an open bottom. It is tapered so that it can be fitted inside and outside the fitting portion 24 .

鍔部33には、被嵌合部34に対して蓋体内側に、上向きに膨らむ凸条部35が蓋体全周に渡り設けてある。本実施形態では凸条部35を蓋体全周に設けてあるが、これに限定されるものではなく、蓋体周方向に間隔を開けて設けてもよい。この場合、蓋体全周の半分以上の長さを占めるように設けるのが好ましい。
凸条部35は、図5に示すように、蓋体3を容器本体2に嵌合させた際に、上縁面部25の容器本体内側の縁部25aの上方付近に配置されるようにしてある。これにより、蓋体3を容器本体2に嵌合する際に、収容物が容器本体2内を揺れ動いたとしても周壁面部22沿いに移動し、上縁面部25の容器本体内側の縁部25aから上方に舞い上がり、凸条部35内へ収容物が入り込むことになる。凸条部35により収容物が止められ、嵌合部24及び被嵌合部34部分への収容物の侵入を防ぐことができるため、噛み込みが発生しにくくなる。
凸条部35を蓋体全周に設ければ、凸条部35に収まった収容物が周方向へ分散でき、より一層に嵌合部への侵入の発生を防ぐことができる。
The flange portion 33 is provided with a protruding portion 35 that bulges upward on the inner side of the lid with respect to the fitted portion 34 over the entire circumference of the lid. In the present embodiment, the ridges 35 are provided on the entire circumference of the lid, but are not limited to this, and may be provided at intervals in the circumferential direction of the lid. In this case, it is preferable to provide it so as to occupy more than half the length of the entire circumference of the lid.
As shown in FIG. 5, when the lid 3 is fitted to the container body 2, the ridges 35 are arranged above the edge 25a of the upper edge surface 25 inside the container body. be. As a result, when the lid 3 is fitted to the container body 2, even if the contents sway within the container body 2, they move along the peripheral wall surface 22, and the edge 25a of the upper edge surface 25 on the inside of the container body moves. , soaring upward, and the stored object enters into the protruding streak portion 35.例文帳に追加The protruding portion 35 stops the stored object and prevents the stored object from entering the fitting portion 24 and the fitted portion 34, so that it is less likely to be caught.
By providing the protrusions 35 around the entire circumference of the lid, the stored items contained in the protrusions 35 can be distributed in the circumferential direction, and the occurrence of intrusion into the fitting portion can be further prevented.

蓋体3を嵌合する前に、凸条部25を基準として容器本体2の周壁面部22から外側にはみ出した収容物があることを認識しやすく、収容物の嵌合部への侵入を予防し、噛み込みを防ぐことができる。また、凸条部35により、この付近に隙間ができ、鍔部35と上縁面部25とによる挟持力が弱まり、収容物が挟まれにくくなる。 Before fitting the lid body 3, it is easy to recognize that there is a contained object protruding outside from the peripheral wall surface part 22 of the container body 2 with reference to the protruded line part 25, and the intrusion of the contained object into the fitting part is easily recognized. prevent and prevent bites. Moreover, the protrusion 35 creates a gap in the vicinity thereof, weakening the gripping force between the flange 35 and the upper edge surface 25, making it difficult for the stored items to be pinched.

凸条部35は、より詳細には、図5に示すように、上縁面部25の容器本体内側の縁部25aの位置(破線A、但しリブ部22bを設けた場合は破線B)よりも凸条部35の蓋体内側縁部(破線C)が蓋体内側に位置するようにするのが好ましい。 More specifically, as shown in FIG. 5, the ridge portion 35 is located at the position of the edge portion 25a inside the container body of the upper edge surface portion 25 (broken line A, but broken line B when the rib portion 22b is provided). It is preferable that the lid inner edge portion (broken line C) of the ridge portion 35 is positioned inside the lid.

凸条部35は、被嵌合部34の高さを凸条部35の高さよりも高くするのが好ましい。これにより、容器外側から視認した際に凸条部35が被嵌合部34により隠れ、容器1を陳列した際に凸条部35が視認されにくく、容器の美観を損なうことがない。 It is preferable that the protruding portion 35 has a height of the fitted portion 34 higher than the height of the protruding portion 35 . As a result, when viewed from the outside of the container, the projecting portion 35 is hidden by the fitted portion 34, and when the container 1 is displayed, the projecting portion 35 is hardly visible, and the container does not spoil its appearance.

凸条部35は、形状を特に限定するものではなく、断面三角形状、半円状、角状などにすることができる。特に、断面三角形状に形成するのが好ましく、図6に示すように、側壁面部32の傾斜角度(θa)と凸条部35の傾斜角度(θb)とを相違させるのがよい。特に、凸条部35の傾斜角度(θb)を側壁面部32の傾斜角度(θa)よりも緩やかにするのが好ましい。これにより、購買者が容器1の内部を確認するために側壁面部32を覗くと、凸条部35の傾斜角度(θb)が異なるため反射などにより凸条部35付近の内部が視認されにくく、購買者が収容物を注視するようにすることができる。 The shape of the protruding portion 35 is not particularly limited, and may be triangular, semicircular, angular, or the like in cross section. In particular, it is preferable to form the cross section in a triangular shape, and as shown in FIG. In particular, it is preferable to make the inclination angle (θb) of the ridge portion 35 gentler than the inclination angle (θa) of the side wall surface portion 32 . As a result, when a purchaser looks into the side wall surface portion 32 to check the inside of the container 1, the difference in the inclination angle (θb) of the ridge portion 35 makes it difficult for the purchaser to visually recognize the interior near the ridge portion 35 due to reflection or the like. The purchaser can be made to watch the contents.

蓋体3を容器本体2に嵌合させた際に、図5に示すように、鍔部33と上縁面部25とが全周に渡り接しない、つまりこれらの間に若干幅の空間Sができるようにするのが好ましい。これにより、鍔部33と上縁面部25との間に隙間ができるため、この間に収容物が挟み込まれにくくなる。 When the lid body 3 is fitted to the container body 2, as shown in FIG. 5, the flange portion 33 and the upper edge surface portion 25 are not in contact with each other over the entire circumference. It is preferable to be able to do so. As a result, a gap is formed between the flange portion 33 and the upper edge surface portion 25, so that the stored object is less likely to be caught in the gap.

以下、容器本体2及び蓋体3の製造方法の一例を説明する。
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、容器本体2は、薄肉の非発泡樹脂シート、薄肉の発泡樹脂シートのいずれでもよいが、非発泡樹脂シートが好ましく、蓋体3は、非発泡樹脂シートが好ましい。
An example of a method for manufacturing the container body 2 and the lid 3 will be described below.
The container body 2 and the lid body 3 are not particularly limited, but can be manufactured by thermoforming a synthetic resin sheet. The synthetic resin sheet may be either a thin non-foamed resin sheet or a thin foamed resin sheet for the container body 2 , but preferably a non-foamed resin sheet, and a non-foamed resin sheet for the lid 3 .

非発泡樹脂シートの場合には、具体的には、厚みが0.1mm~2.0mmの範囲内、特に0.2mm~1.2mmの範囲内のシートを用いるのが好ましい。
発泡樹脂シートの場合には、厚みが0.5mm~4.0mmの範囲内、特に0.7mm~2.2mm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1.05倍~20.0倍、特に1.5倍~15.0倍にするのが好ましい。
In the case of a non-foamed resin sheet, specifically, it is preferable to use a sheet having a thickness within the range of 0.1 mm to 2.0 mm, particularly within the range of 0.2 mm to 1.2 mm.
In the case of a foamed resin sheet, it is preferable to use a sheet having a thickness within the range of 0.5 mm to 4.0 mm, particularly within the range of 0.7 mm to 2.2 mm. In the case of a foamed resin sheet, the expansion ratio is preferably 1.05 to 20.0 times, particularly 1.5 to 15.0 times.

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 resin sheets such as polystyrene resin sheets, polyethylene terephthalate resin sheets, and modified polyethylene terephthalate resin sheets with heat resistance. A thermoplastic resin sheet such as a base resin sheet can be used. Materials that can withstand heating in a microwave oven, such as heat-resistant polystyrene resin sheets, polypropylene resin sheets, and modified polyethylene terephthalate resin sheets with heat resistance, may also 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。
As the foamed resin sheet, for example, a foamed polyolefin resin sheet, a foamed polystyrene resin sheet, and a foamed polyester resin sheet such as foamed polyethylene terephthalate can be used.
A laminated sheet obtained by laminating a synthetic resin sheet can also be used, and examples of the laminated sheet include a laminated sheet obtained by thermally laminating a resin film to a non-foamed resin sheet or a foamed resin sheet, a laminated sheet obtained by a coextrusion method, and a laminated sheet obtained by an extrusion lamination method. Laminated sheets and the like can be mentioned.

非発泡樹脂シート、発泡樹脂シート及び積層シートとして、バイオマスプラスチックを用いてもよい。
バイオマスプラスチックとは、原料として再生可能な有機資源由来の物質を含み,化学的又は生物学的に合成することにより得られる高分子材料をいう。バイオマスプラスチックは、石油由来の樹脂と比して、大気中への二酸化炭素の排出量を抑えることができ、環境への負荷を低減できる。
バイオマスプラスチックとしては、例えば、ポリ乳酸樹脂、バイオマスポリエチレン、バイオマスポリエチレンテレフタレートなどが挙げられる。
A biomass plastic may be used as the non-foamed resin sheet, the foamed resin sheet, and the laminated sheet.
Biomass plastics refer to polymer materials obtained by chemically or biologically synthesizing substances derived from renewable organic resources as raw materials. Compared to petroleum-derived resins, biomass plastics can reduce the amount of carbon dioxide emitted into the atmosphere and reduce the burden on the environment.
Examples of biomass plastics include polylactic acid resin, biomass polyethylene, and biomass polyethylene terephthalate.

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。 Thermoforming includes vacuum forming, pressure forming, vacuum pressure forming, hot plate forming, and the like.

容器本体2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。蓋体3は透明であるのが好ましい。また、容器本体2及び蓋体3の表面に、透明乃至半透明の場合は視認性を妨げない程度に、文字、絵柄などの印刷や刻印を施してもよい。例えば、凸条部35、凸条部35付近の鍔部33に印刷を施せば、凸条部35付近から内部が視認されにくくすることができ、陳列時の美感を損なわない。
さらには、補強のためのリブを適宜位置に設けることや滑り止めのためのシボ加工を施してもよい。
容器本体2及び蓋体3の適宜位置に、立方体乃至直方体状などに膨出させたスタック用突起を設けることもできる。
The container body 2 may be colored such as black or white, but is preferably transparent or translucent so that the inside can be visually recognized. The lid 3 is preferably transparent. If the surfaces of the container body 2 and the lid 3 are transparent or translucent, they may be printed with characters, patterns, etc., or stamped to the extent that visibility is not hindered. For example, if the ridges 35 and the flange 33 near the ridges 35 are printed, the inside can be made difficult to see from the vicinity of the ridges 35, and the aesthetic appearance at the time of display is not spoiled.
Furthermore, ribs for reinforcement may be provided at appropriate positions, or texturing may be performed for slip resistance.
A cubic or rectangular parallelepiped stacking protrusion may be provided at an appropriate position on the container body 2 and the lid 3 .

以下、包装用容器1の使用方法の一例を説明する。
包装用容器1は、容器本体2の載置面21bに食料品などの収容物を載せ、蓋体3を容器本体2に被せて上方から押圧し、嵌合部24に被嵌合部34を嵌合させて使用することができる。この際に、蓋体3の凸条部35を基準として、ここからはみ出した収容物がないか確認することができ、なければそのまま蓋体3を押し込むことにより収容物の嵌合部への侵入を防ぎ、噛み込ませずに嵌合させることができる。凸条部35よりもはみ出した収容物があれば、収容物を容器内部に移動させてから嵌合させ、噛み込ませないようにさせることができる。
An example of how to use the packaging container 1 will be described below.
In the packaging container 1, an object such as food is placed on the mounting surface 21b of the container body 2, the lid body 3 is placed on the container body 2 and pressed from above, and the fitted portion 34 is fitted to the fitting portion 24. Can be used by mating. At this time, it is possible to confirm whether or not there is an object protruding from the protrusion 35 of the lid 3 as a reference. can be fitted without biting. If there is a stored item protruding from the protruding line portion 35, the stored item can be moved into the container and then fitted to prevent it from being bitten.

包装用容器1を開蓋するには、例えば、右手の親指と人差し指で容器本体2の摘み部26を摘み、左手の親指と人差し指で蓋体の摘み部36を摘み、本体2側を下方に引きつつ、蓋体3側を上方に引くことにより被嵌合部34を嵌合部24から外すことができる。 To open the lid of the packaging container 1, for example, the thumb and forefinger of the right hand grip the knob 26 of the container body 2, the thumb and index finger of the left hand grip the gripping portion 36 of the lid, and the main body 2 side is turned downward. The fitted portion 34 can be removed from the fitting portion 24 by pulling the lid 3 side upward while pulling.

包装用容器1は、容器本体2に蓋体3を嵌合させた際に、鍔部33と上縁面部25とが接しないようにし、この間に空間Sの隙間ができるようにすれば、収容物が噛み込まれにくくなる。 When the lid 3 is fitted to the container body 2, the packaging container 1 can be accommodated by preventing the brim 33 and the upper edge surface 25 from coming into contact with each other and creating a space S between them. Makes it harder for things to get stuck.

また、被嵌合部34の高さを凸条部35の高さよりも高くすれば、容器1を店頭などに陳列した際に凸条部35が被嵌合部34に隠れて視認されにくくなり、容器1の外観印象がよくなる。 Further, if the height of the fitted portion 34 is higher than the height of the protruded portion 35, the protruded portion 35 is hidden by the fitted portion 34 and becomes less visible when the container 1 is displayed in a store or the like. , the appearance impression of the container 1 is improved.

さらには、凸条部35を断面三角形状とし、側壁面部32の傾斜角度と相違させることにより、購買者が容器の内部を確認するために側壁面部を覗くと、凸条部の傾斜角度が異なるため反射などにより凸条部内部が認識しにくくなり、この付近にある収容物が視認されにくく、購買者が収容物を注視するようになる。 Furthermore, by forming the protruding portion 35 into a triangular cross section and making it different from the inclination angle of the side wall surface portion 32, the inclination angle of the protruding portion is different when the purchaser looks into the side wall surface portion to check the inside of the container. Therefore, it becomes difficult to recognize the inside of the protruding portion due to reflection or the like, and it is difficult to visually recognize the contained items in the vicinity thereof, so that the purchaser will pay attention to the contained items.
