本発明は、断熱容器に関し、特に、上端側に向かい若干拡径される円筒形状の側壁を有し、上端側に開口部、下端側に底部が形成されるカップ形状の断熱容器に関する。   The present invention relates to a heat insulating container, and more particularly to a cup-shaped heat insulating container having a cylindrical side wall that is slightly enlarged in diameter toward the upper end side, and having an opening on the upper end side and a bottom on the lower end side.

カップ麺などの容器入り食品に使用される断熱容器が広く知られている。このような断熱容器のうち、上端側に向かい若干拡径される円筒形状等の側壁を有し、上端側に開口部、下端側に底部が形成されるカップ容器も広く知られている。このようなカップ容器では、上端側の開口部から内部に広がる収容凹部に食品が収容され、上端側の開口部が蓋体で閉じられることにより密封状態が保持される。開口部の径方向外側の周囲には、カップ容器の強度を保持するためにリング形状に突出したフランジ部が設けられ、このフランジ部に蓋体がヒートシールされることにより、蓋体で収容凹部を密封し、収容凹部に収容されている食品を衛生的に保護している。   Insulated containers used for foods in containers such as cup noodles are widely known. Among such heat insulating containers, a cup container having a cylindrical side wall or the like that is slightly enlarged toward the upper end side and having an opening at the upper end side and a bottom at the lower end side is also widely known. In such a cup container, food is stored in a storage recess that extends inward from the opening on the upper end side, and the sealed state is maintained by closing the opening on the upper end side with a lid. In order to maintain the strength of the cup container, a flange portion protruding in a ring shape is provided around the outside of the opening in the radial direction. The food stored in the storage recess is hygienically protected.

特許第４９５８３２６号Patent No. 4958326

特許文献１には、このようなカップ容器において、プラスチック製のカップ容器を薄肉化した場合に、耐落下衝撃性が低下すること、及び、フランジ部にうねりが生じ、フランジ部のシール性が悪化するという課題が記載されている。特許文献１では、この課題を解決するための方法として、フランジ部の厚さを所定値より厚くし、フランジ部に１または複数の溝を設ける発明が記載されている。   In Patent Document 1, in such a cup container, when the plastic cup container is thinned, the drop impact resistance is lowered, and the flange part is swelled, and the sealing performance of the flange part is deteriorated. The problem of doing is described. In Patent Document 1, as a method for solving this problem, an invention in which the thickness of the flange portion is made thicker than a predetermined value and one or a plurality of grooves is provided in the flange portion is described.

しかしながら、特許文献１には、粉末スープ等をバラ充填する場合に、収容凹部の周囲の蓋体のシール面とフランジの上面との間の隙間に粉末スープ等が残る可能性があるという問題についての記載はない。   However, Patent Document 1 discloses a problem that powder soup or the like may remain in the gap between the sealing surface of the lid around the housing recess and the upper surface of the flange when filling the powder soup or the like in bulk. There is no description.

また、このようなカップ容器では、断熱性を必要とするため、断熱性を有するプラスチック等を使用し、射出成形により製造することが一般に行われているが、カップ容器の形状によっては、樹脂が押し切れずショートモールドになるおそれがある。   In addition, since such a cup container requires heat insulation, it is generally performed by injection molding using plastic or the like having heat insulation, but depending on the shape of the cup container, resin may be used. There is a risk of short molding without pressing.

また、カップラーメン、カップスープ、カップみそ汁、カップ雑炊等の高温の食品や、アイスクリームなど低温の食品を収容凹部に収容する場合には、カップ容器の側壁部に複数の縦方向の断熱リブを設け、使用者が手で持ったときに熱が伝わらないようにする構造も一般に知られている。しかしながら、断熱リブの形状によっては、カップ容器を覆うシュリンクフィルムが破れるおそれがある。   In addition, when storing hot foods such as cup ramen, cup soup, cup miso soup, and cups, and cold foods such as ice cream in the storage recess, a plurality of vertical heat insulation ribs are provided on the side wall of the cup container. A structure that is provided and prevents heat from being transferred when the user holds it by hand is also generally known. However, the shrink film covering the cup container may be broken depending on the shape of the heat insulating rib.

また、カップ容器の強度を上げるために、カップ容器の側壁の外周面に厚肉部を設けることも知られているが、従来の形状では、喫食時にカップ容器の撓む可能性があるという問題もある。   In addition, in order to increase the strength of the cup container, it is also known to provide a thick portion on the outer peripheral surface of the side wall of the cup container, but the conventional shape may cause the cup container to bend during eating. There is also.

従って、本発明の目的は、カップ麺などの容器入り食品に使用されるカップ形状を有する断熱容器において、上述の従来の問題を解決できる新規な断熱容器を提供することである。   Accordingly, an object of the present invention is to provide a novel heat insulating container capable of solving the above-described conventional problems in a heat insulating container having a cup shape used for foods in containers such as cup noodles.

上記課題を解決するために、本発明の断熱容器は、プラスチックで射出成形により形成され、上端側に向かい若干拡径される形状の側壁を有し、上端側に開口部、下端側に底部が形成されるカップ形状の断熱容器であって、上記カップ形状の上記側壁の外周面に、縦方向に延在し、所定の間隔を空けて配設される複数の断熱リブと、上記開口部の径方向外側の全周にリング形状に突出したフランジ部であって、当該フランジ部は、径方向外側に向かって延設された横延設部と、当該横延設部の先端から下方に向かって延設された下延設部とから構成されるフランジ部とを備え、上記横延設部の上部の上記開口部の端部に接する位置に、円環形状の突起部であるシール突起部が形成されることを特徴とする。   In order to solve the above problems, the heat insulating container of the present invention is made of plastic by injection molding, has a side wall that is slightly enlarged in diameter toward the upper end side, an opening on the upper end side, and a bottom on the lower end side. A cup-shaped heat insulating container to be formed, and a plurality of heat insulating ribs extending in the vertical direction on the outer peripheral surface of the cup-shaped side wall and arranged at a predetermined interval, and the opening A flange portion that protrudes in a ring shape around the entire outer periphery in the radial direction, the flange portion extending from the distal end of the laterally extending portion and the laterally extending portion that extends outwardly in the radial direction. A seal projection that is a ring-shaped projection at a position in contact with the end of the opening at the top of the lateral extension Is formed.

また、上記下延設部の先端の内周に、面取り部が形成されるものとしてもよい。   Further, a chamfered portion may be formed on the inner periphery of the tip of the lower extending portion.

また、上記複数の断熱リブは、上記カップ形状の上端側から、上記カップ形状の下端から所定の位置まで延設され、上記複数の断熱リブの下端側には、下端側に向かい高さが０になるまで次第に低くなるテーパ部が形成されるものとしてもよい。   The plurality of heat insulation ribs extend from the upper end side of the cup shape to a predetermined position from the lower end of the cup shape, and the lower end side of the plurality of heat insulation ribs has a height of 0 toward the lower end side. It is good also as what forms the taper part which becomes low gradually until it becomes.

また、上記カップ形状の上記側壁の外周面の中段部分には、上端側から下端側に向かい肉厚が次第に厚くなり、更に肉厚が次第に薄くなる形状を有する厚肉部が形成されるものとしてもよい。   In addition, a thick portion having a shape in which the thickness gradually increases from the upper end side toward the lower end side and further decreases in thickness is formed in the middle portion of the outer peripheral surface of the cup-shaped side wall. Also good.

本発明によれば、上述の従来の問題を解決できる、カップ麺などに使用されるカップ形状を有する新規な断熱容器を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the novel heat insulation container which has the cup shape used for cup noodles etc. which can solve the above-mentioned conventional problem can be provided.

以下、本発明の実施形態を、図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の断熱容器１００の縦断面図であり、図２は、本発明の断熱容器１００の底面図であり、図３は、本発明の断熱容器１００を重ねた状態を示す部分断面図である。   FIG. 1 is a longitudinal sectional view of a heat insulation container 100 of the present invention, FIG. 2 is a bottom view of the heat insulation container 100 of the present invention, and FIG. 3 is a portion showing a state in which the heat insulation containers 100 of the present invention are stacked. It is sectional drawing.

図１乃至図３において、本発明の断熱容器１００は、カップ麺などの容器入り食品に使用される容器であって、上端側に向かい若干拡径される円筒形状の側壁１０１を有し、上端側に開口部１０１ａ、下端側に底部１０２が形成されるカップ形状を有する。なお、ここでは、側壁１０１のカップ形状は、円筒形状としたがこれには限定されず、四角柱等の多角柱形状でもよく、また、開口部１０１ａが円形で、底部１０２が四角形等の多角形など、開口部１０１ａと底部１０２の形状が異なっていてもよい。   1 to 3, the heat insulating container 100 of the present invention is a container used for food containing containers such as cup noodles, and has a cylindrical side wall 101 that is slightly enlarged toward the upper end side. It has a cup shape in which an opening 101a is formed on the side and a bottom 102 is formed on the lower end side. Here, the cup shape of the side wall 101 is a cylindrical shape, but is not limited to this, and may be a polygonal column shape such as a quadrangular prism, and the opening 101a is circular and the bottom 102 is a square shape. The shapes of the opening 101a and the bottom 102 may be different, such as a square shape.

カップ形状の断熱容器１００は、上端側の開口部１０１ａから内部に広がる収容凹部１０３に食品が収容され、上端側の開口部１０１ａが図示を省略する蓋体で閉じられることにより密封状態が保持される。収容凹部１０３には、カップラーメン、カップスープ、カップみそ汁、カップ雑炊等の高温の食品や、アイスクリームなど低温の食品を収容する必要があるため、カップ形状の断熱容器１００は、断熱性を有するプラスチック等の材料を使用して射出成形により形成される。   In the cup-shaped heat insulating container 100, food is stored in a storage recess 103 that extends inward from the opening 101 a on the upper end side, and the sealed state is maintained by closing the opening 101 a on the upper end side with a lid (not shown). The Since it is necessary to accommodate hot food such as cup ramen, cup soup, cup miso soup, and cups and cold food such as ice cream in the housing recess 103, the cup-shaped heat insulating container 100 has heat insulation properties. It is formed by injection molding using a material such as plastic.

図１に示すように、断熱容器１００の開口部１０１ａの径方向外側の全周には、カップ容器の強度を保持するためにリング形状に突出したフランジ部１０４が設けられる。フランジ部１０４には、上述の蓋体がヒートシールされ、これにより蓋体で収容凹部１０３を密封し、収容凹部１０３に収容されている食品を衛生的に保護している。フランジ部１０４は、後述する図４（ｂ）に示すように、概略、径方向外側に向かって延設された横延設部１０４ａと、横延設部１０４ａの先端から下方に向かって延設された下延設部１０４ｂとから構成される。フランジ部１０４の詳細な形状については、図４（ａ）及び図４（ｂ）を使用して、以下で詳細に説明する。   As shown in FIG. 1, a flange portion 104 protruding in a ring shape is provided on the entire outer periphery in the radial direction of the opening 101 a of the heat insulating container 100 in order to maintain the strength of the cup container. The above-mentioned lid body is heat-sealed on the flange portion 104, whereby the housing recess 103 is sealed with the lid body, and the food stored in the housing recess 103 is hygienically protected. As shown in FIG. 4B, which will be described later, the flange portion 104 is roughly extended in a radially extending portion 104a extending outward in the radial direction, and extending downward from the front end of the horizontally extending portion 104a. And the lower extended portion 104b. The detailed shape of the flange portion 104 will be described in detail below with reference to FIGS. 4 (a) and 4 (b).

また、図３に示すように、断熱容器１００の側壁１０１の外周面には、縦方向に延在し、所定の間隔を空けて配設される複数の断熱リブ１０５が形成される。断熱リブ１０５は、高温や低温の食品を収容凹部１０３に収容した場合に、使用者が手で持ったときに熱が伝わらないようにするための構造である。断熱リブ１０５の形状については、図５（ａ）及び図５（ｂ）を使用して、以下で詳細に説明する。   As shown in FIG. 3, a plurality of heat insulating ribs 105 are formed on the outer peripheral surface of the side wall 101 of the heat insulating container 100 so as to extend in the vertical direction and be arranged with a predetermined interval. The heat insulation rib 105 is a structure for preventing heat from being transmitted when a user holds it by hand when food at a high temperature or low temperature is accommodated in the accommodation recess 103. The shape of the heat insulating rib 105 will be described in detail below with reference to FIGS. 5A and 5B.

また、図１に示すように、断熱容器１００の側壁１０１の外周面の中段部分には、上端側から下端側に向かい肉厚が次第に厚くなり、更に肉厚が次第に薄くなる形状を有する厚肉部１０６が形成される。厚肉部１０６は、使用者が喫食する場合に、カップ形状の断熱容器１００が撓むのを防止するために設けられる。厚肉部１０６の形状については、図６（ａ）及び図６（ｂ）を使用して、以下で詳細に説明する。   Further, as shown in FIG. 1, the middle portion of the outer peripheral surface of the side wall 101 of the heat insulating container 100 has a thick wall shape that gradually increases in thickness from the upper end side toward the lower end side and further decreases in thickness. A portion 106 is formed. The thick portion 106 is provided to prevent the cup-shaped heat insulating container 100 from being bent when the user eats. The shape of the thick portion 106 will be described in detail below with reference to FIGS. 6 (a) and 6 (b).

さらに、断熱容器１００は、図３に示すように、食品が収容されていない状態では、重ねた状態で搬送されるため、側壁１０１の内周面の底部１０２より若干、開口部１０１ａ側の位置に、段部１０７が形成される。段部１０７が形成されることにより、断熱容器１００が重ねられた場合に、上側のカップ形状の断熱容器１００´の下端面が下側のカップ形状の断熱容器１００の段部１０７に接触し、互いに平行を保った状態で安定して固定できる。   Further, as shown in FIG. 3, since the heat insulating container 100 is transported in a stacked state in a state where no food is contained, the position of the insulating container 100 is slightly closer to the opening 101 a side than the bottom 102 of the inner peripheral surface of the side wall 101. In addition, a stepped portion 107 is formed. By forming the stepped portion 107, when the heat insulating containers 100 are stacked, the lower end surface of the upper cup-shaped heat insulating container 100 ′ contacts the stepped portion 107 of the lower cup-shaped heat insulating container 100, It can be stably fixed in a state where they are parallel to each other.

図４（ａ）は、従来のフランジ部４０４の拡大断面図であり、図４（ｂ）は、本発明のフランジ部１０４の拡大断面図である。   4A is an enlarged cross-sectional view of a conventional flange portion 404, and FIG. 4B is an enlarged cross-sectional view of the flange portion 104 of the present invention.

図４（ａ）において、従来のフランジ部４０４は、本発明のフランジ部１０４と同様に、概略、径方向外側に向かって延設された横延設部４０４ａと、横延設部４０４ａの先端から下方に向かって延設された下延設部４０４ｂとから構成される。更にフランジ部４０４の横延設部４０４ａの上面には、容器の強度を保つために、２つの円環形状の突起部４０４ｃが形成されている。しかしながら、このような従来のフランジ部４０４では、突起部４０４ｃの位置が開口部４０１の端部から離れているため、粉末スープ等をバラ充填する場合に、開口部４０１の周囲の蓋体のシール面とフランジ部４０４の上面との間の隙間に粉末スープ等が残る可能性があるという問題があった。   In FIG. 4 (a), the conventional flange portion 404, like the flange portion 104 of the present invention, is roughly extended in the radially outward direction and the distal end of the laterally extended portion 404a. It is comprised from the downward extension part 404b extended toward the downward direction from. Further, two annular projections 404c are formed on the upper surface of the laterally extending portion 404a of the flange portion 404 in order to maintain the strength of the container. However, in such a conventional flange portion 404, since the position of the projection portion 404c is separated from the end portion of the opening portion 401, when the powder soup or the like is filled in a bulk, the lid seal around the opening portion 401 is sealed. There was a problem that powder soup and the like may remain in the gap between the surface and the upper surface of the flange portion 404.

これに対して、図４（ｂ）に示すように、本発明のフランジ部１０４では、横延設部１０４ａの上部の開口部１０１ａの端部に接する位置に、円環形状の突起部であるシール突起部１０４ｃが形成される。シール突起部１０４ｃは、開口部１０１ａの端部に接する位置に設けられるため、蓋体のシール面とフランジ部１０４の上面との間の隙間は生じず、粉末スープ等が残る可能性がなくなる。また、シール突起部１０４ｃを設けることにより、フランジ部１０４の強度が維持でき、蓋体とのヒートシールが安定して行える。   On the other hand, as shown in FIG. 4 (b), the flange portion 104 of the present invention is an annular projection at a position in contact with the end of the opening 101a at the top of the laterally extending portion 104a. A seal protrusion 104c is formed. Since the seal protrusion 104c is provided at a position in contact with the end of the opening 101a, there is no gap between the seal surface of the lid and the upper surface of the flange portion 104, and there is no possibility of powder soup remaining. Further, by providing the seal protrusion 104c, the strength of the flange portion 104 can be maintained, and heat sealing with the lid can be performed stably.

また、図４（ｂ）に示すように、本発明のフランジ部１０４には、さらに、下延設部１０４ｂの先端の内周に面取り部１０４ｄが設けられる。図４（ａ）に示す従来のフランジ部４０４の下延設部４０４ｂには、このような面取り部が設けられていなかったため、プラスチックで射出成形により成形した場合に、樹脂が押し切れずショートモールドになるおそれがあった。本発明のフランジ部１０４では、面取り部１０４ｄが設けられているため、このようなショートモールドを避けることができる。   Further, as shown in FIG. 4B, the flange portion 104 of the present invention is further provided with a chamfered portion 104d on the inner periphery of the tip of the lower extending portion 104b. Since the conventional extending portion 404b of the flange portion 404 shown in FIG. 4 (a) is not provided with such a chamfered portion, the resin is not completely pressed when it is molded by injection molding with plastic. There was a risk of becoming. In the flange portion 104 of the present invention, since the chamfered portion 104d is provided, such a short mold can be avoided.

図５（ａ）は、従来の断熱リブ５０５の下端部の拡大断面図であり、図５（ｂ）は、本発明の断熱リブ１０５の下端部の拡大断面図である。   FIG. 5A is an enlarged cross-sectional view of a lower end portion of a conventional heat insulation rib 505, and FIG. 5B is an enlarged cross-sectional view of a lower end portion of the heat insulation rib 105 of the present invention.

図５（ａ）に示すように、従来の断熱リブ５０５は、カップ容器の下端まで延びる形状に形成され、さらに、従来の断熱リブ５０５の下端部には、テーパ処理などが施されていない。このため、従来の断熱リブ５０５の形状では、カップ容器を覆うシュリンクフィルムが破れるおそれがあった。   As shown in FIG. 5A, the conventional heat insulation rib 505 is formed in a shape extending to the lower end of the cup container, and the lower end portion of the conventional heat insulation rib 505 is not subjected to taper processing or the like. For this reason, in the shape of the conventional heat insulation rib 505, there exists a possibility that the shrink film which covers a cup container may be torn.

これに対して、図５（ｂ）に示すように、本発明の断熱リブ１０５は、カップ形状の上端側から、カップ形状の下端から所定の位置まで延設される形状に形成され、断熱リブ１０５の下端側には、下端側に向かい高さが０になるまで次第に低くなるテーパ部１０５ａが形成される。断熱リブ１０５をこのような形状とすることにより、カップ形状の断熱容器１００を覆うシュリンクフィルムが破れる可能性を低くすることができる。   On the other hand, as shown in FIG. 5 (b), the heat insulation rib 105 of the present invention is formed in a shape extending from the upper end side of the cup shape to a predetermined position from the lower end of the cup shape. On the lower end side of 105, a tapered portion 105a that gradually decreases toward the lower end side until the height becomes zero is formed. By making the heat insulating rib 105 into such a shape, the possibility that the shrink film covering the cup-shaped heat insulating container 100 is torn can be reduced.

図６（ａ）は、従来の厚肉部６０６の拡大断面図であり、図６（ｂ）は、本発明の厚肉部１０６の拡大断面図である。   FIG. 6A is an enlarged cross-sectional view of a conventional thick portion 606, and FIG. 6B is an enlarged cross-sectional view of the thick portion 106 of the present invention.

図６（ａ）に示すように、従来の厚肉部６０６は、階段形状に形成され、カップ容器の強度を上げていた。しかしながら、このような形状では、カップ容器内に食品が収容され、使用者が喫食する場合には、カップ容器を手で持ったときに強度が更に必要となり、カップ容器が撓むおそれがあった。   As shown in FIG. 6A, the conventional thick portion 606 is formed in a stepped shape and increases the strength of the cup container. However, in such a shape, when food is stored in the cup container and the user eats, when the cup container is held by hand, further strength is required, and the cup container may be bent. .

これに対して、図６（ｂ）に示すように、本発明の断熱容器１００では、カップ形状の断熱容器１００の側壁１０１の外周面の中段部分に、上端側から下端側に向かい肉厚が次第に厚くなり、更に肉厚が次第に薄くなる形状を有する厚肉部１０６が形成される。厚肉部１０６をこのような形状とすることにより、従来の階段形状の厚肉部６０６と比較して、階段形状の頂点をストレートに繋ぐ形状となり、肉厚がさらに厚くなり、カップ形状の断熱容器１００の側壁１０１の強度を増加させることができ、喫食時のカップ容器の撓みを抑制できる。   On the other hand, as shown in FIG. 6 (b), in the heat insulating container 100 of the present invention, the thickness of the middle portion of the outer peripheral surface of the side wall 101 of the cup-shaped heat insulating container 100 increases from the upper end side to the lower end side. A thick portion 106 having a shape that gradually increases in thickness and gradually decreases in thickness is formed. By forming the thick portion 106 in such a shape, compared to the conventional staircase-shaped thick portion 606, the top of the staircase shape is connected straight, the wall thickness is further increased, and the cup-shaped heat insulation The strength of the side wall 101 of the container 100 can be increased, and bending of the cup container at the time of eating can be suppressed.

以上のように、本発明の断熱容器によれば、蓋体のシール面とフランジの上面との間の隙間に粉末スープ等が残る、樹脂が押し切れずショートモールドが発生する、断熱リブの形状によりカップ容器を覆うシュリンクフィルムが破れる可能性がある、及び、使用者の喫食時にカップ容器に撓みが発生するなどの従来の問題を解決できる、カップ麺などに使用されるカップ形状を有する新規な断熱容器を提供できる。   As described above, according to the heat insulating container of the present invention, the shape of the heat insulating rib, in which powder soup or the like remains in the gap between the sealing surface of the lid and the upper surface of the flange, the resin cannot be pressed and a short mold occurs. A novel film having a cup shape used for cup noodles and the like that can solve the conventional problems such as the shrinkage of the shrink film covering the cup container and the occurrence of bending of the cup container at the time of eating by the user. An insulated container can be provided.
