Description

本考案は、熱可塑性樹脂シートからなり、食品などを包装する食品容器に関する。   The present invention relates to a food container made of a thermoplastic resin sheet and packaging foods and the like.

食品容器は、運搬や陳列するために積み重ねられることがある。このため、容器が押し潰され変形しないようにリブを設けたり、形状を凝らしたりして剛性をもたせている。
例えば、側壁に多数のリブを設けた容器(下記特許文献1参照)や、天面部と側壁部の境界部に糸尻状凸部を設けた容器(下記特許文献2参照)などが開発されている。
Food containers may be stacked for transportation and display. For this reason, ribs are provided to prevent the container from being crushed and deformed, and the shape is made to give rigidity.
For example, a container having a large number of ribs on the side wall (see Patent Document 1 below), a container having a thread-bottom protrusion on the boundary between the top surface and the side wall part (see Patent Document 2 below), and the like have been developed. Yes.

従来の食品容器は、上記特許文献1の図4にも示すように、蓋部の側壁面と上面又は容器本体部の側壁面と底面の接合部は、滑らかに円弧状に形成されていた。
本考案者は、鋭意研究した結果、接合部を円弧状に形成すると容器の剛性が弱まることを見出して本考案を成し得た。
In the conventional food container, as shown in FIG. 4 of Patent Document 1, the joint between the side wall surface and the upper surface of the lid portion or the side wall surface and the bottom surface of the container main body portion is smoothly formed in an arc shape.
As a result of diligent research, the inventor has found that the rigidity of the container is weakened when the joint portion is formed in an arc shape, and has achieved the present invention.

そこで、本考案の目的は、従来と略同じ形状でも剛性に優れ、シート厚を薄くすることができる食品容器を提供することにある。   Accordingly, an object of the present invention is to provide a food container that is excellent in rigidity even in substantially the same shape as the conventional one and that can reduce the sheet thickness.

本考案の食品容器は、熱可塑性樹脂シートからなり、蓋部の側壁面と上面との接合部及び/又は容器本体部の側壁面と底面との接合部を角張らせて形成した角部としたことを特徴とする。   The food container of the present invention is made of a thermoplastic resin sheet, and has a corner portion formed by angling the joint portion between the side wall surface and the top surface of the lid portion and / or the joint portion between the side wall surface and the bottom surface of the container body portion. It is characterized by that.

このような構成とすることにより、角部で荷重を支えることができ、蓋部及び/又は容器本体部の剛性が強まり、変形しにくい食品容器になり、そのため、従来の容器と比較してシート厚を薄くすることができる。   By adopting such a configuration, it is possible to support the load at the corners, and the lid and / or the container main body has increased rigidity, resulting in a food container that is not easily deformed. The thickness can be reduced.

上記食品容器は、前記角部の角度を90°〜120°とすることが好ましい。   In the food container, the angle of the corner is preferably 90 ° to 120 °.

研究した結果、角度をこの範囲内にすることにより、特に剛性の優れた食品容器になる。   As a result of research, by setting the angle within this range, a food container having particularly excellent rigidity is obtained.

以下、本考案の第一実施形態の食品容器を説明する。

As shown in FIG. 1, a food container 1 according to an embodiment of the present invention is formed in a substantially rectangular shape in plan view, and includes a lid portion 2 and a container main body portion 3.
The food container 1 is made of, for example, a thermoplastic resin sheet such as a polystyrene resin sheet, a polyethylene resin sheet, a polypropylene resin sheet, or a polyethylene terephthalate resin sheet, such as vacuum molding, pressure molding, vacuum pressure molding, hot plate molding, or the like. It can be manufactured by thermoforming.

蓋部2は、側壁面2aと上面2bとを有し、側壁面2aと上面2bとの接合部4は、図2に示すように、それぞれの面を交差させ角張らせた角部5として形成し、つまり、円弧状にせずに形成してある。
角部5の角度(図2のX)は、90°〜120°にするのがよく、この範囲であると剛性が特に優れたものとなる。
角部5は、熱成形する際、型を角張らせておくことなどにより形成することができる。
また、側壁面2aと上面2bの周縁には縦方向のリブ2cが複数形成してあり、このようにリブ2cを設けるとより剛性が増したものとなる。
The lid portion 2 has a side wall surface 2a and an upper surface 2b, and the joint portion 4 between the side wall surface 2a and the upper surface 2b is formed as a corner portion 5 that intersects and squares each surface as shown in FIG. It is formed, that is, not formed in an arc shape.
The angle of the corner 5 (X in FIG. 2) is preferably 90 ° to 120 °, and the rigidity is particularly excellent within this range.
The corner 5 can be formed by, for example, keeping the mold square when thermoforming.
Further, a plurality of longitudinal ribs 2c are formed on the peripheral edges of the side wall surface 2a and the upper surface 2b. When the ribs 2c are provided in this way, the rigidity is further increased.

容器本体部3は、内部を区画して複数の収納部6を設けてあり、各収納部6は、側壁面3aと底面3bを有し、側壁面3aと底面3bとの接合部7は、図2に示すように、それぞれの面を交差させ角張らせた角部8として形成し、つまり、円弧状にせずに形成してある。
角部8の角度(図2のY)は、90°〜120°にするのがよく、この範囲であると剛性が特に優れたものとなる。
角部8は、上記角部5と同様に、熱成形する際、型を角張らせておくことなどにより形成することができる。
また、側壁面3aと底面3bの周縁には縦方向のリブ3cが複数形成してあり、このようにリブ3cを設けるとより剛性が増したものとなる。
The container body 3 is partitioned into a plurality of storage portions 6, each storage portion 6 has a side wall surface 3 a and a bottom surface 3 b, and a joint portion 7 between the side wall surface 3 a and the bottom surface 3 b is As shown in FIG. 2, each surface is formed as a corner portion 8 that intersects and is angled, that is, is formed without an arc shape.
The angle of the corner portion 8 (Y in FIG. 2) is preferably 90 ° to 120 °, and the rigidity is particularly excellent within this range.
The corner 8 can be formed by, for example, keeping the mold square during thermoforming, as with the corner 5 described above.
Further, a plurality of longitudinal ribs 3c are formed on the peripheral edges of the side wall surface 3a and the bottom surface 3b. If the ribs 3c are provided in this way, the rigidity is further increased.

食品容器1は、蓋部2の側壁面2aと上面2bとの接合部4を、円弧状にせず角部5として形成し、また、容器本体部3の側壁面3aと底面3bとの接合部7を、円弧状にせず角部8として形成したため、剛性に優れたものである。そのため、従来と比較してシート厚の薄い食品容器1とすることができる。
上記実施形態では、複数の収納部6を形成してあるが、これに限定するものではなく、少なくとも一つの収納部を有する食品容器としてあればよい。
In the food container 1, the joint portion 4 between the side wall surface 2 a and the upper surface 2 b of the lid portion 2 is formed as a corner portion 5 instead of an arc shape, and the joint portion between the side wall surface 3 a and the bottom surface 3 b of the container main body portion 3. 7 is formed as a corner portion 8 without being arcuate, and thus has excellent rigidity. Therefore, it can be set as the food container 1 with a thin sheet | seat thickness compared with the past.
In the said embodiment, although the several accommodating part 6 is formed, it is not limited to this, What is necessary is just to be a food container which has at least 1 accommodating part.

上記実施形態において、図3に示すように、リブを設けない食品容器1aとすることもできる。
このようにしても、剛性があり、従来と比較してシート厚の薄い食品容器とすることができる。
