Abstract

<P>PROBLEM TO BE SOLVED: To provide a container having its lid surely fitted with a container body even if the outer diameter of the body varies. <P>SOLUTION: A lidded container consists of the container body 1 press-formed of a paper sheet and the lid 2 made of plastic to be put over the container body 1, and is equipped with flanges 3 and 4 along the outer peripheries of the container body 1 and the lid 2 wherein the flange 3 of the container body 1 is held by the flange 4 of the lid 2, a protrusion 5 formed on the inner periphery of the flange 4 of the lid 2 is engaged with the flange 3 of the body 1, and the container body 1 and the lid 2 are fitted with each other. A small-diameter part 6 and a large-diameter part 7 are formed on the flange 4 of the lid 2, and difference in sizes between the parts 6 and 7 shrinks the difference from the outer diameter of the flange 3 of the container body 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明は、段ボール等の紙シートをプレス成形した容器本体と、プラスチック製の蓋とから成る容器に関するものである。   The present invention relates to a container comprising a container main body obtained by press-molding a paper sheet such as cardboard and a plastic lid.

例えば、食品等を収納する容器として、図６に示すように、段ボール等の紙シートをプレス成形した容器本体５１と、この容器に被せるプラスチック製の蓋５２とから成り、容器本体５１及び蓋５２の外周にフランジ５３，５４を設け、蓋５２のフランジ５４の内周に突条５５を形成し、蓋５２のフランジ５４で容器本体５１のフランジ５３を抱き込み、突条５５を容器本体５１のフランジ５３に係合させて、容器本体５１と蓋５２とを嵌合させるものが考えられている。   For example, as shown in FIG. 6, a container for storing food or the like includes a container main body 51 formed by press-molding a paper sheet such as cardboard and a plastic lid 52 that covers the container. Flanges 53 and 54 are provided on the outer periphery of the lid 52, and a protrusion 55 is formed on the inner periphery of the flange 54 of the lid 52. The flange 53 of the container body 51 is held by the flange 54 of the lid 52, and the protrusion 55 is attached to the container body 51. It is considered that the container body 51 and the lid 52 are engaged with each other by engaging with the flange 53.

ところで、上記容器本体５１は、成形した後、時間が経過すると、プレスによる紙シートの折曲角度が浅くなり、フランジ５３の外径が大きくなる傾向がある。   By the way, when time elapses after the container body 51 is molded, the folding angle of the paper sheet by the press tends to become shallow, and the outer diameter of the flange 53 tends to increase.

また、成形時の紙シートの含水率や金型の表面温度の違いなどにより、フランジ５３の外径には、微妙な個体差が生じる。   Further, due to differences in the moisture content of the paper sheet during molding and the surface temperature of the mold, there are subtle individual differences in the outer diameter of the flange 53.

このため、蓋５２のフランジ５４を、フランジ５３の外径が小さい容器本体５１に対応するように製作すると、フランジ５３の外径が大きい容器本体５１には、蓋５２が嵌まらなくなる恐れがある。   For this reason, if the flange 54 of the lid 52 is manufactured so as to correspond to the container main body 51 having a small outer diameter of the flange 53, the lid 52 may not fit into the container main body 51 having a large outer diameter of the flange 53. is there.

また、蓋５２のフランジ５４を、フランジ５３の外径が大きい容器本体５１に対応するように製作すると、フランジ５３の外径が小さい容器本体５１には、蓋５２が緩くなって係合しなくなる恐れがある。   Further, if the flange 54 of the lid 52 is manufactured so as to correspond to the container main body 51 having the large outer diameter of the flange 53, the lid 52 becomes loose and does not engage with the container main body 51 having the small outer diameter of the flange 53. There is a fear.

そこで、この発明は、容器本体の外径が異なっても、蓋が容器本体に確実に嵌合する蓋付き容器を提供しようとするものである。   Therefore, the present invention is intended to provide a container with a lid that allows the lid to be securely fitted to the container body even if the outer diameter of the container body is different.

上記課題を解決するため、この発明は、紙シートをプレス成形した容器本体と、この容器本体に被せるプラスチック製の蓋とから成り、蓋のフランジの内周に形成した突条を容器本体のフランジに係合させて、容器本体と蓋とを嵌合させる蓋付き容器において、前記蓋のフランジに小径部と大径部とを形成したのである。   In order to solve the above problems, the present invention comprises a container body formed by press-molding a paper sheet, and a plastic lid that covers the container body, and a protrusion formed on the inner periphery of the flange of the lid is provided with the flange of the container body. In the container with a lid for engaging the container body and the lid, a small diameter portion and a large diameter portion are formed on the flange of the lid.

このように、蓋のフランジに小径部と大径部とを形成すると、容器本体のフランジの外径が小さい場合には、小径部の突条が容器本体のフランジに係合して、容器本体と蓋とが確実に嵌合し、容器本体のフランジの外径が大きい場合には、小径部を押し広げることにより、蓋を容器本体に嵌めることができる。   Thus, when the small diameter part and the large diameter part are formed on the flange of the lid, when the outer diameter of the flange of the container body is small, the protrusion of the small diameter part engages with the flange of the container body, and the container body When the outer diameter of the flange of the container body is large, the lid can be fitted to the container body by expanding the small diameter portion.

まず、この発明の第１実施形態を図１乃至図４に基づいて説明する。   First, a first embodiment of the present invention will be described with reference to FIGS.

図１に示すように、この容器は、段ボールをプレス成形した容器本体１と、この容器に被せるプラスチック製の蓋２とから構成される円盤状のものである。容器本体１及び蓋２の外周には、フランジ３，４が設けられ、蓋２のフランジ４の内周面には、突条５が周方向に断続的に形成されている。   As shown in FIG. 1, this container is a disk-shaped thing comprised from the container main body 1 which press-molded the corrugated cardboard, and the plastic lid | cover 2 which covers this container. Flanges 3 and 4 are provided on the outer circumferences of the container body 1 and the lid 2, and protrusions 5 are intermittently formed in the circumferential direction on the inner circumferential surface of the flange 4 of the lid 2.

また、図１及び図２に示すように、蓋２のフランジ４には、内径が小さい小径部６と、内径が大きい大径部７とが周方向に交互に形成されている。なお、蓋２の周方向における小径部６及び大径部７の配置は、特に限定されるものではない。   As shown in FIGS. 1 and 2, the flange 4 of the lid 2 is alternately formed with small diameter portions 6 having a small inner diameter and large diameter portions 7 having a large inner diameter in the circumferential direction. In addition, arrangement | positioning of the small diameter part 6 and the large diameter part 7 in the circumferential direction of the lid | cover 2 is not specifically limited.

上記のような蓋付き容器では、図３及び図４に実線で示すように、容器本体１のフランジ３の外径が小さい場合に、容器本体１に蓋２を被せると、小径部６の突条５が容器本体１のフランジ３に係合するので、容器本体１と蓋２とが確実に嵌合する。   In the case of a container with a lid as described above, when the outer diameter of the flange 3 of the container body 1 is small as shown in FIG. 3 and FIG. Since the strip 5 engages with the flange 3 of the container body 1, the container body 1 and the lid 2 are securely fitted.

一方、図３及び図４に鎖線で示すように、容器本体１のフランジ３の外径が大きい場合には、蓋２のフランジ４の小径部６を、大径部７と同程度まで押し広げることにより、蓋２を容器本体１に嵌めることができる。   On the other hand, when the outer diameter of the flange 3 of the container body 1 is large, as shown by a chain line in FIGS. 3 and 4, the small diameter portion 6 of the flange 4 of the lid 2 is pushed to the same extent as the large diameter portion 7. Thus, the lid 2 can be fitted to the container body 1.

次に、この発明の第２実施形態を図５に基づいて説明する。なお、ここでは、上記第１実施形態と共通する部分についての説明は省略する。   Next, a second embodiment of the present invention will be described with reference to FIG. In addition, description about the part common to the said 1st Embodiment is abbreviate | omitted here.

この容器は、電子レンジで調理できる蓋付きグラタン皿として使用されるものであり、容器本体１及び蓋２は、一方向に長く、八角形状にやや角張った形状とされ、その長手方向両端部には、把手部８，９がそれぞれ設けられている。   This container is used as a baking dish with a lid that can be cooked in a microwave oven, and the container body 1 and the lid 2 are long in one direction and are slightly squared in an octagonal shape, at both ends in the longitudinal direction. Are provided with handle portions 8 and 9, respectively.

蓋２のフランジ４には、コーナー部に小径部６が形成され、これに隣接する長辺側に大径部７が形成されている。そして、小径部６及び大径部７の内面に、それぞれ突条５が形成されている。   In the flange 4 of the lid 2, a small diameter portion 6 is formed at the corner portion, and a large diameter portion 7 is formed on the long side adjacent to the corner portion. And the protrusion 5 is formed in the inner surface of the small diameter part 6 and the large diameter part 7, respectively.

このような容器においても、容器本体１のフランジ３の外径が小さい場合には、蓋２の小径部６の突条５が容器本体１に係合して、容器本体１と蓋２とが確実に嵌合し、容器本体１のフランジ３の外径が大きい場合には、小径部６を大径部７と同程度まで押し広げることにより、蓋２を容器本体１に嵌めることができる。   Even in such a container, when the outer diameter of the flange 3 of the container body 1 is small, the protrusion 5 of the small-diameter portion 6 of the lid 2 is engaged with the container body 1 so that the container body 1 and the lid 2 are connected. When the outer diameter of the flange 3 of the container main body 1 is large enough to be securely fitted, the lid 2 can be fitted to the container main body 1 by pushing the small diameter portion 6 to the same extent as the large diameter portion 7.
