本发明提供的超薄注塑多格独立密封食品容器，包括容器体和可盖合到容器 体或与之分离的盖体。食品容器包括设置在容器体中央部位的中间容纳部、围绕 中间容纳部设置的外围容纳部和多重密封结构。第一实施例和第二实施例， 中间 容纳部具有适于盛放汤类食物的结构，而第三实施例和第四实施例，中间容纳部 具有适于酱料调味品的结构。
首先参照图 1至图 10所示的第一实施例， 该食品容器包括：
容器体 1, 具有中间容纳部 11、 围绕该中间容纳部 11分布的多个外围容纳 部 12。 每个容纳部均具有底部 13、 环绕底部 13并向上延伸的侧壁 14、 内密封 壁 16。其中， 外围容纳部 12的侧壁 14顶端可形成大致平行于底部 13延伸的平 台部 15， 内密封壁 16环绕该平台部 15并向上延伸到容纳部开口边缘。 各容纳 部 12具有环绕其内密封壁 16设置的侧向突出的卡扣部 161。各容纳部的底部形 成有向上突起的堆叠嵌合部 131。 各容纳部开口的相对边之间由平缘 17相互连 接， 各外围容纳部开口的外侧边向外延伸形成唇边 18, 唇边外缘向下并向外延 伸形成倾斜的外密封壁 19。 在本实施例中， 容器体 1的中间容纳部 11呈碗状， 并且与外围容纳部 12具有相同的深度。
盖体 2， 具有可分别与容器体 1的中间容纳部 11和各外围容纳部 12的幵口 配合的中间盖合部 21和多个外围盖合部 22,各盖合部均具有一底部平台 23、以 及环绕该底部平台 23并向上延伸的内密封壁 24。各盖合部具有环绕其内密封壁 24设置的侧向突出的卡扣部 241。 各盖合部的底部平台 23形成有向上突起的堆 叠嵌合部 231。各盖合部的内密封壁 24顶端相对边之间由平缘 25相互连接， 各 外围盖合部 22的内密封壁 24外侧边向外延伸形成唇边 26，唇边 26外缘向下延 伸形成外密封壁 27, 外密封壁 27的内侧面具有凸起 28。
使用时， 容器体 1的中间容纳部 11可用于盛放一定量的汤类食物， 外围容 纳部 12可用于盛放米饭、 以及干的或汤汁较少的菜肴。 当盖体 2盖合到容器体 1即可形成一种可方便地同时存放和携带不同种类食品的密封食品容器。具体说 明如下： 盖体 2与容器体 1配合后， 容器体 1的外密封壁 19向外顶持盖体 2的 外密封壁 27内侧面，同时外密封壁 27的凸起 28锁扣外密封壁 19的下端部，形 成外层的密封部和抗压部。盖体 2的中间盖合部 21和外围盖合部 22配合别到容 器体 1的中间容纳部 11和外围容纳部 12的开口中， 容器体 1的内密封壁 16和 盖体 2的内密封壁 24通过对应的卡扣部 161、 241相互卡扣， 由此形成内层的密 封部和抗压部。 容器体 1的各容纳部之间的平缘 17与盖体 2的各盖合部之间的 平缘 25、 以及容器体 1的唇边 18与盖体 2的唇边 26在水平面上形成中间的密 封部和抗压防脱部。 进一步的， 当平缘 17和平缘 25之间、 唇边 18与唇边 26 之间形成有结合密封部时可进一步提高密封效果，该结合密封部可以是凸沿或网 状结构，具体可参照公告号为 CN2855930 (公告日 2007. 01. 10)的实用新型专利。 因此，当盖体 2扣合到容器体 1后可形成多重密封结构，不仅具有良好的静态密 封性能，而且具备良好的抗压变形、抗热变形的特性，可保证容器在各种使用状 态下均能有效防止食物汤汁特别是汤类食物的泄漏，同时可使各容纳部之间形成 密封隔离， 防止容器内的不同类食品汤汁互相渗透、 串味。
当盖体 2从容器体 1分离后， 容器体 1可作为餐盘使用。 由于中间容纳部 11设置在容器体 1中央部位、 而外围容纳部 12围绕中间容纳部 11设置， 因此 在开启盖体 1及食用过程中汤汁不容易溢出。 上述容器体 1、 盖体 2的结构还具有以下优点： 能够将多个容器体 1、 多个 盖体 2垂直堆叠放置， 以便于包装、搬运。 并且由于容器体 1、 盖体 2分别设置 有可相互配合的堆叠嵌合部 131、 231， 因此能够将多个食品容器垂直堆叠， 便 于携带。
图 11示出超薄注塑多格独立密封食品容器的第二实施例， 其结构与第一实 施例相似， 区别在于容器体 1的中间容纳部 11、 外围容纳部 12的形状， 外围容 纳部 12的数量， 以及盖体 2的中间盖合部 21、 外围盖合部 22的形状， 外围盖 合部 22的数量。

用于制造容器体 1、盖体 2的材料，可在目前公知的多种聚合物材料中选择。 优选的是可回收再利用并适于通过热注射模具成型的材料，例如聚丙烯树脂 PP。 材料中可根据需要添加各种添加剂，只要其符合容纳和包装食品的使用要求。这 些材料可以是透明的， 也可以是不透明的。用于制造容器体 1、 盖体 2的工艺和 设备也是公知。优选的，采用热注射模具成型， 以提供具有较髙的成型质量和表 面质量的薄壁制品。容器体 1、盖体 2的壁厚优选的是在 0. 5毫米至 0. 8毫米之 间， 然而根据需要， 采用更薄或更厚的壁厚也是可行的。
参照图 12至图 19所示的第三实施例， 容器体 1具有中间容纳部 31、 围绕 该中间容纳部 31分布的多个外围容纳部 32。盖体 2具有可分别与容器体 1的中 间容纳部 31和各外围容纳部 32的开口配合的中间盖合部 41和多个外围盖合部 42。 在该实施例中， 中间容纳部 31设计成口径较小和较浅的圆盘状， 以适于盛 放酱料调味品，避免使用空间的浪费和影响食用。其外围容纳部和多重密封结构 的结构和功能与第一、 二实施例相同， 不再赘述。
使用时， 容器体 1的中间容纳部 31可用于盛放一定量的酱料调味品， 以满 足食用时调味需要。 外围容纳部 32可用于盛放各类食物。 当盖体 2盖合到容器 体 1 即形成一种可方便地同时存放和携带不同种类食品和酱料调味品的密封食 品容器。同样的， 由于具有多重密封结构，可保证容器在各种使用状态下均能有 效防止食物汤汁和酱料调味品的泄漏，同时可使各容纳部之间形成密封隔离，防 止容器内的不同类食品汤汁互相渗透、 串味。 由于中间容纳部 31设置在容器体 2中央部位、而外围容纳部 32围绕中间容纳部 31设置， 因此在开启盖体 2及食 用过程中汤汁和酱料调味品不容易溢出。
图 20示出超薄注塑多格独立密封食品容器的第四实施例， 其结构与第三实 施例相似， 区别在于容器体 1的中间容纳部 31、 外围容纳部 32的形状， 外围容 纳部 32的数量， 以及盖体 2的中间盖合部 41、 外围盖合部 42的形状， 外围盖 合部 42的数量。
本发明提供的食品容器适用于但不限于作为包装、携带和存放不同种类外买 食品的容器， 作为微波加热或冷藏的食物容器和作为用餐的餐盘使用。
