【考案の属する技術分野】[Technical field to which the device belongs]

本考案は、発泡ポリスチレンシートから成形される容器本体と蓋体とからなる 食品包装用等のワンウエイ包装用容器に関する。 The present invention relates to a one-way packaging container, such as a food packaging, which comprises a container body and a lid formed from a foamed polystyrene sheet.

【0002】[0002]

【従来の技術】[Prior art]

従来、ほぼ方形の発泡ポリスチレンシート製食品包装用容器においては、容器 本体に対してその外周より大きい外周部を持つ蓋体をかぶせるか、または容器本 体のフランジ部内周に、本体より外周の小さい蓋体を落とし込み式に嵌める形式 で容器本体と蓋体とを係止させていた。この形式で蓋体を係止させる場合には、 容器本体の最外周部をほぼ垂直に上げるか、または蓋体の最外周部をほぼ垂直に 下げてやや長くした形状に成形し、蓋体または容器本体の長くした最外周部を嵌 め込んで圧接することにより係止するのが一般的であった。 Conventionally, in a substantially rectangular expanded polystyrene sheet food packaging container, the container body is covered with a lid having an outer peripheral portion larger than the outer periphery, or the outer peripheral portion of the container main body is smaller than the outer periphery of the main body. The container body and the lid were locked in a manner that the lid was fitted in a drop-in manner. When locking the lid in this way, raise the outermost periphery of the container body almost vertically or lower the outermost periphery of the lid almost vertically to form a slightly longer shape. It was common to lock the container body by fitting it into the elongated outermost part and pressing it.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

ところが、上記従来の発泡ポリスチレンシート製の容器においては、コーナー 部を除いて容器の縁がほぼ直線状であるため容器本体と蓋体の圧接による摩擦力 が小さく、容器本体に蓋体を一定の強度で係止するためには、容器のコーナー部 付近の丸くなった部分で両者を圧接してそこの摩擦力によっていた。従って容器 の本体と蓋体の係止が不十分で、内容食品を収納した後に容器の蓋の部分をつか んで持ち上げた場合に、容器本体が脱落して内容食品がこぼれてしまうことがあ った。 However, in the conventional foam polystyrene sheet container described above, since the edges of the container are almost linear except for the corners, the friction force due to the pressure contact between the container body and the lid is small, and the lid is fixed on the container body. In order to lock with strength, the two were pressed against each other at the rounded part near the corner of the container and the frictional force there was applied. Therefore, if the container body and lid are not sufficiently locked, the container body may fall out and the food contents may be spilled when the container lid is grasped and lifted after storing the food contents. It was

【0004】 本考案は上記のような事情に鑑みて提案されたもので、容器本体に食品がほぼ いっぱいに収納された場合、その蓋の部分だけをつかんで持ち上げても容器本体 が脱落することがなく、しかも人が手で両者を簡単・確実に着脱することができ る発泡ポリスチレンシート製蓋付包装用容器を提供することを目的とする。The present invention has been proposed in view of the above-mentioned circumstances, and when food is almost filled in the container body, the container body may fall off even if only the lid portion is grasped and lifted. It is an object of the present invention to provide an expanded polystyrene sheet-made packaging container with a lid, which can be easily and surely put on and taken off by a person by hand without any problem.

【課題を解決するための手段】[Means for Solving the Problems]

すなわち本考案は、発泡ポリスチレンシートから熱成形された、コーナー部に 丸みを有するほぼ方形の容器本体と、その容器本体を覆う蓋体とからなる包装容 器において、容器本体および蓋体のいずれか一方の4隅のコーナー部の内側に、 他方の蓋体または容器本体の周縁部を嵌め合わせるための凹部を有することを特 徴とする蓋付包装用容器である。 That is, the present invention relates to a packaging container including a substantially rectangular container body having a rounded corner at a corner, which is thermoformed from an expanded polystyrene sheet, and a lid body that covers the container body. A packaging container with a lid, characterized in that it has concave portions for fitting the other peripheral portion of the lid body or the main body of the container inside the corner portions of the four corners.

【0006】[0006]

【考案の実施の形態】[Embodiment of device]

この蓋付包装用容器の容器本体または蓋体の4隅のコーナー部に形成される嵌 め合わせるための凹部は、1カ所の長さが容器の蓋体または容器本体の周縁部全 周長さの1%以上13%以下、望ましくは4%以上9%以下である。1カ所の凹 部の長さが容器の蓋体または容器本体の周縁部長さの1%未満では、蓋体と容器 本体とを嵌め合わせて蓋を閉じたとき、両者を係止する力が小さ過ぎるため十分 な脱落防止効果を得ることができず、また、周縁部の長さの13%を越えると両 者を係止する力が必要以上に大きくなって、両者を簡単に着脱することが難しく なり、かつ電子レンジ等で加熱した場合に内部から発生する水蒸気の圧力を逃が しにくくなったりするので好ましくない。 The fitting recesses formed at the four corners of the container body or lid of this packaging container with a lid have a length of one place that is the entire circumference of the peripheral edge of the container lid or container body. 1% or more and 13% or less, preferably 4% or more and 9% or less. When the length of one concave portion is less than 1% of the length of the peripheral portion of the container lid or the container body, when the lid and the container body are fitted together and the lid is closed, the force that locks both is small. Therefore, it is not possible to obtain a sufficient fall-off prevention effect. Also, if it exceeds 13% of the length of the peripheral edge, the force that locks both parties becomes unnecessarily large and they can be easily attached and detached. It is not preferable because it becomes difficult and it becomes difficult to release the pressure of water vapor generated from the inside when heated in a microwave oven or the like.

【0007】 嵌め合わせ用の凹部の深さは、0.2mm乃至2.0mmの範囲が好ましい。 深さが0.2mm未満では十分な嵌め合わせ効果が得られず、また2.0mmを 越えると嵌め合わせの効果が大き過ぎて蓋が開きにくくなると共に、成形時に凹 部の形成が困難になるため好ましくない。The depth of the recess for fitting is preferably in the range of 0.2 mm to 2.0 mm. If the depth is less than 0.2 mm, a sufficient fitting effect cannot be obtained, and if it exceeds 2.0 mm, the fitting effect is too great and the lid becomes difficult to open, and it becomes difficult to form a recess during molding. Therefore, it is not preferable.

【0008】 本考案による蓋付包装用容器は、発泡ポリスチレンのシートを加熱軟化させて 、雄型および雌型を用いて例えば真空成形法等で製作することができる。The lidded packaging container according to the present invention can be manufactured by heating and softening a foam polystyrene sheet and using a male mold and a female mold, for example, by a vacuum molding method or the like.

【0009】 上記の構成により、本考案による蓋付包装用容器は、容器本体に内容食品を入 れ、蓋体をかぶせて4隅を手で少し押圧すれば、嵌め合わせ用凹部に相手側の4 隅の周縁部が係合して、容器本体と蓋体とが安定に係止され、蓋の部分だけをつ かんで持ち上げた場合でも、容器本体の中に入れた内容食品の重量による脱落を 効果的に防止することができる。また蓋体を取り外す場合には、例えば容器本体 を片手で持ち、蓋体の上記4隅の係合部の1乃至2か所を別の手で上方に軽く引 っ張れば、容易に係合が解除されて、蓋体を容器本体から取り外すことができる 。容器が落とし蓋方式の場合は、容器本体の相対するコーナー部を少し押圧して 容器本体を変形させ、他方の手で蓋体の凸部を持って引っ張れば簡単に係合が解 除され取り外すことができる。With the above-mentioned structure, the packaging container with a lid according to the present invention is configured such that the container body is filled with the content food, the lid body is covered, and the four corners are slightly pressed by hand, so that the mating concave portion of the mating side is formed. The peripheral edges of the four corners are engaged so that the container body and lid are stably locked, and even if only the lid is lifted, it falls off due to the weight of the food contained in the container body. Can be effectively prevented. When removing the lid, for example, hold the container body with one hand and pull one or two of the four corner engaging portions of the lid lightly with another hand to engage the lid easily. Is released, the lid can be removed from the container body. If the container is a drop lid type, slightly press the opposite corners of the container body to deform the container body, and with the other hand hold the convex portion of the lid body and pull it, the engagement is easily released and removed. be able to.

【実施例】【Example】

以下、本考案による蓋付包装用容器を、図に示す実施例に基づいて具体的に説 明する。図1は本考案による蓋付包装用容器の一実施例を示す斜視図、図2はそ の平面図、図3および図4はそれぞれ図2におけるA−A線およびB−B線に沿 う拡大断面図である。 Hereinafter, the packaging container with a lid according to the present invention will be specifically described based on the embodiment shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a packaging container with a lid according to the present invention, FIG. 2 is a plan view thereof, and FIGS. 3 and 4 are taken along lines AA and BB in FIG. 2, respectively. It is an expanded sectional view.

【0011】 図1乃至図4において、1は容器本体、2は蓋体であり、発泡ポリスチレンシ ート(株式会社JSP製・LF210NAMI)を用いて真空成形機(中央化学 株式会社製・1個取り真空成形機)によりそれぞれ別体として成形されている。 その容器本体1は平面ほぼ方形の、上面開口部が底面よりやや広い箱状で、4 隅のコーナー部3は丸みを有し、上縁部は全周にわたり外側に僅かに屈曲させて 屈曲部4が形成されている。In FIGS. 1 to 4, 1 is a container main body, 2 is a lid, and a vacuum molding machine (manufactured by Chuo Kagaku Co., Ltd., 1 piece) using a foamed polystyrene sheet (manufactured by JSP, LF210NAMI) Vacuum forming machine). The container body 1 has a substantially square shape in a plan view, a box-like opening whose upper surface is slightly wider than the bottom surface, four corners 3 are rounded, and an upper edge is slightly bent outward along the entire circumference. 4 are formed.

【0012】 蓋体2は、容器本体1の上面開口部の全面を覆う大きさ形状に形成され、4隅 を除く周縁部5は図3に拡大断面を示した通り、容器本体1の上縁の屈曲部4に 蓋体2の段部6を介して多少内側に締まり気味に接するようになっている。 蓋体2の4隅のコーナー部7には、図4の拡大断面図に示したように、嵌め合 わせのための凹部8が形成され、ここに容器本体1の上縁屈曲部4が嵌め込まれ て容器本体1と蓋体2が係止される構造である。本実施例においては、蓋体2の 縁の外周長さ560mmに対して、凹部8の長さL(図2)が30mm(5.4 %)、深さは1.2mmとした。 段部6の上方はさらに一段高くなり、中央部が平たく少し窪んだ形(図1)で 蓋体2全体が形成される。The lid body 2 is formed in a size shape that covers the entire upper surface opening of the container body 1, and the peripheral edge portion 5 except for the four corners is as shown in the enlarged cross section of FIG. The bent portion 4 is slightly inwardly contacted via the stepped portion 6 of the lid body 2 so as to come into contact with the bent portion 4. As shown in the enlarged sectional view of FIG. 4, concave portions 8 for fitting are formed in the four corner portions 7 of the lid body 2, and the upper edge bent portions 4 of the container body 1 are fitted therein. Thus, the container body 1 and the lid 2 are locked. In this embodiment, the length L (FIG. 2) of the recess 8 was 30 mm (5.4%) and the depth was 1.2 mm with respect to the outer peripheral length of 560 mm of the lid 2. The upper part of the stepped portion 6 is further raised by one step, and the entire lid body 2 is formed in a shape in which the central portion is flat and slightly depressed (FIG. 1).

【0013】 この構成による蓋付包装用容器の本体に300gの米飯を詰めて、蓋体を嵌め 合わせて閉じた後、容器の蓋の部分だけをつかんで持ち上げるテストを50個の サンプルについて行った結果、容器本体が蓋体から脱落したものは0であった。The body of the packaging container with a lid having this configuration was filled with 300 g of cooked rice, the lids were fitted together and closed, and then the test of lifting only the lid portion of the container was performed on 50 samples. As a result, it was 0 that the container body had fallen off from the lid.

【0014】 これらのサンプルについて片方の手で容器本体を持ち、他の手で蓋の4隅のう ち相隣なる2か所を持ち上げて容器を開くテストを試みたが、従来の容器に比べ ると多少力を要する程度であって、特に開きにくいことはなかった。For these samples, an attempt was made to open the container by holding the container body with one hand and lifting two adjacent four corners of the lid with the other hand. Then, it required a little force, and it was not particularly difficult to open.

【0015】 比較例として、4隅のコーナー部に嵌め合わせのための凹部を設けない従来の 同材質の容器について同様のテストを試みた結果、50個中3個のものが脱落し た。As a comparative example, as a result of attempting a similar test with a conventional container of the same material having no recesses for fitting at the four corners, 3 out of 50 dropped out.
