其中, 所述凸啮合件包括从所述凸啮合件所在的容器壳体 的顶部内表面向 外突出的主体 部分以及至少一对从所述主体 部分相对的两侧延伸且背 向彼此的 凸出部, 所述主体部分具有头部, 所述一对凸出部各具有面向所述头部 的第一 侧面和与所述第 一侧面相对的且远离所述头部 的第二侧面, 所述第二侧面相对 于正交方 向成锐角延伸, 其中所述正交方向是与所述凸啮合件的纵向轴线垂直 的方向; 以及 所述凹啮合件的形状及尺寸 与所述凸啮合件相匹配以实现 匹配啮合, 使所 述第一容器壳 体和所述第二容器壳体的顶部 彼此密封接合, 由此密封式封闭所 述容器本体 的顶部。 所述凸出部的第二侧面相对于 正交方向成锐角朝向或离开所 述主体部分的 头部一侧延伸 。 根据本发明的优选实施例, 所述第二侧面相对于正交方向成锐 角朝向所述主 体部分的头部一侧延伸。 较佳地,所述凸出部的第二侧面与所述 正交方向形成的锐角在 10。-30。, 优 选地选自以下角度 之一: 10。、15。、18。、20。和 22。。 此外, 所述凸出部的第一侧 面相对于所述正 交方向成锐角朝向离开所述主 体部分的头部一侧延伸, 以利于 所述凸啮合件插 入所述凹啮合件相啮合。 本发明的要点之一在于凸啮合 件的形状, 具体地, 凸啮合件包括主体部分 及从所述主体 部分两侧延伸的凸出部。 由于凸出部的第一侧面和第二侧面被构 造成与凸啮合件 纵向轴线的正交方向均为锐角, 凸出部的形状适合于模制成型 加工。 同时, 发明人在研究过程中发现, 本发明的凸啮合件及凸出部的锐角形 状能够仅通过按压使 密封机构闭合, 同时实现优异的密封效果, 容器中的液体 不会漏出到容 器外部; 并且密封机构容易开封, 再次密封。 根据本发明的袋式容器的优选 的实施方式, 所述袋式容器由包含硅胶或橡 胶的材料制 成。 硅胶 ( silicone) 是一种无毒性、耐高温、 低温并且易于模制加 工的聚合物材 料。 使用硅胶或橡胶制成的袋式容器适合于食品的储存 。 根据本发明的袋式容器是一体 化成型制造的。 优选地, 所述第一容器壳体 和所述第二容 器壳体的两侧边缘有一部分是一 体成型连接的, 所述一体成型连 接的部分是从 所述底边缘延伸至所述容器本 体的整体高度的 2/5至 9/10处;

其中, 所述凸啮合件包括从所述凸啮合件所在的容器壳体 的顶部内表面向 外突出的主体 部分, 所述主体部分具有至少一个波形区段, 在与所述凸啮合件 所在的容器壳 体平行的第一平面中, 所述波形区段沿所述主体部分 的长度方向 的横截面轮廓包 括至少一个峰部或谷部 ; 以及 所述凹啮合件的形状及尺寸 与所述凸啮合件相匹配以实现 匹配啮合, 使所 述第一容器壳 体和所述第二容器壳体的顶部 彼此密封接合, 由此密封式封闭所 述容器本体 的顶部。 在一优选实施例中, 所述主体部分在包含所述凸啮合件的纵 向轴线且垂直 于所述第一平 面的第二平面中具有大致三 角形轮廓, 所述轮廓可以具有直的侧 部。 在另一优选实施例中, 所述主体部分的外端处设置头部, 所述头部与所述 主体部分形成 T形构件, 在包含所述凸啮合件的纵向轴线且垂直于所述第一平 面的第二平面 中具有大致 T形轮廓。 所述头部的外侧面倒角, 并且内侧面相对 于所述凸啮合件 的纵向轴线成锐角延伸。 容器壳体的厚度即是袋式 容器的壁厚, 可以取决于容器的容积而恰当地选 择。 当容积较大时, 可以使容器壁具有较大的厚度, 使得容器不会由于内容物 的重量过大而破 裂。 根据本发明的袋式容器的优选 的实施方式, 所述袋式容器还包括位于顶部 的握持部, 以有利于容器的开启和闭合。 附图说明 图 1是根据本发明的第一实施例的袋式 容器的示意图, 所示袋式容器已模 制成型但其两 侧边缘接近敞开顶部的部分未进行接 合处理。 图 2是图 1所示的袋式容器的俯视图。 图 3是图 2沿线 I-I的截面图。 图 4示出图 1的 A部分的放大示意图, 示出待进行接合处理的区域。 图 5示出图 4的 B部分的放大示意图。 图 6A和 6B是图 1所示的袋式容器的密封机构 的截面示意图,分别示出凹 啮合件和凸啮合件 的截面形状。 图 7是图 6A和 6B所示的凹啮合件和凸啮合件准 备啮合的示意图。 图 8A和图 8B分别示出根据本发明的第二实施例的袋式容器 的两个容器壳 体上的波形 凸啮合件和波形凹啮合件的立体 示意图。 图 9A和图 9B分别示出图 8A的 C部分和图 8B的 D部分的放大示意图。 图 10是图 8A的波形凸啮合件的截面示意图 。 图 11是图 8A和图 8B所示的波形凸啮合件和波 形凹啮合件啮合后的截面 示意图。 图 12A是图 8A的波形凸啮合件的替代实施 例的立体示意图。 图 12B是图 12A所示的替代实施例的波形凸啮合件与其对应的波形 凹啮合 件啮合后的截面 示意图。 图 13是图 8A所示的另 一替代实施例的波形凸啮合件 与其对应的波形凹啮 合件啮合后 的截面示意图。 具体实施方式 虽然本发明以优选实施例作说明和 描述, 但是袋式容器可以许多不同的构 型、 尺寸、 和材料来制造。 以下将参考附图,描述本发明的具有密封机构的袋式 容器的示例性实施例。 应当理解, 在附图中各个部分的尺寸不按 比例描绘, 仅作示意说明, 不代表本 发明产品的真实尺 寸。 参看图 1至图 7, 图中示出了根据本发明的一个实施例构造的袋式容器。 如图 1所示, 袋式容器包括容器本体, 该容器本体包括相对配置的第一容器壳 体 1和第二容器壳体 2, 第一容器壳体 1和第二容器壳体 2的底边缘互相密封 连接形成所述袋 式容器的底部 3 , 并且第一容器壳体 1和第二容器壳体 2的相 应的两个侧边缘互相 密封连接形成所述袋式容器 的两侧 4, 5, 由此限定该袋式 容器的内部容 积及敞开的顶部 6。袋式容器还包括设置在顶部 6的握持部 7, 以 有利于容器 的开启和闭合。 图 1所示的袋式容器是一体化成型制 造的, 具有大致矩形的外部形状。 如 图 1和图 3所示, 第一容器壳体 1和第二容器壳体 2的两侧边缘从其底边缘开 始的一半 以上的高度是一体成型连接的 。优选地,根据袋式容器的大小和类型, 所述一体成 型连接的部分是从底边缘开始延伸 至容器本体的整体高度的 2/5至 9/10处, 优选为 1/2至 4/5处。 此处的 “容器本体的整体高度” 是指袋式容器 的容器本体 的高度, 即袋式容器的底部 3至顶部 6的高度。 图 1所示的袋式容器为已模制成型 , 但其两侧边缘接近敞开顶部的部分未 进行接合处理 。 如图所示, 第一容器壳体 1和第二容器壳体 2的相应的两个侧 边缘的上部 尚未接合。 这样做的好处是, 在袋式容器的模制过程中, 容器具有 较大的开口; 该设计有利于袋式容器的一体化成 型制造过程, 也便于成型后的 脱模处理。 在袋式容器成型并脱模后, 第一容器壳体 1和第二容器壳体 2的两 个侧边缘的未一体 成型连接的部分 (即图 4所示的阴影部分) 通过接合处理而 互相密封连接 。所述述接合处理可以使用粘合剂粘合, 或者使用热熔处理接合。 取决于袋式容 器的用途, 粘合剂应该符合相应的安全标准。 热熔接合的条件可 以取决于袋式 容器的材料恰当地选择。 图 4至图 7示出袋式容器的密封机构, 所述密封机构设置在容器本体的顶 部上。在本实施例中,密封机构包括位 于第一容器壳体 1上的凹啮合件 10和位 于第二容器壳 体 2上的凸啮合件 20。 如图 1所示, 凹啮合件 10和凸啮合件 20 分别沿着第一容 器壳体 1和第二容器壳体 2的顶部内表面的整个横向长度延伸。 在图 4所示的两个容器壳体 1 , 2的侧边缘的未一体成型连接的部分通过接合处 理而互相连接 后, 凸啮合件 20的末端部分已经插入凹啮合件 10, 使得容器的 顶部开口在整个 开口长度被密封机构完全覆盖 ,从而确保袋式容器的密封效果 o 凹啮合件 10和凸啮合件 20的截面形状在图 6A、6B和图 7中清楚示出。 凸啮合件 20包括从第二容器壳体 2的顶部内表面垂直地向外突出的主体部 分 21以及从所述主体部分 21相对的两侧延伸且背向彼此的两对凸出部 22, 23 , 24, 25 o 主体部分 21具有头部 211 , 所述凸出部 22, 23 , 24, 25各具有面向 所述头部 211一侧的第一侧面 221 , 231 , 241 , 251以及分别与所述第一侧面相 对且离开所述头 部 211一侧的第二侧面 222, 232, 242, 252。 凸啮合件 20的 纵向轴线 Y被定义为从第二容器壳体 2的顶部内表面至主体部分 21的头部 211 的方向, 与凸啮合件 20的纵向轴线 Y垂直的方向为正交方向。 凸出部 22, 23 , 24, 25的第二侧面 222, 232, 242, 252分别相对于正交轴线 Zl , Z2成锐角朝 向所述头部 211一侧方向延伸。 根据图 6A、6B和图 7所示的方向, 袋式容器的敞开顶部向上, 第一容器壳 体 1位于左侧,第二容器壳体 2位于右侧, 凸啮合件 20从第二容器壳体 2的顶 部内表面 向左垂直地凸出。 位于主体部分 21之上的凸出部 22, 24的第二侧面 222, 242向上朝向头部 211一侧的方向延伸, 第二侧面 222, 242的延伸方向 与正交轴线 Zl , Z2均形成锐角。根据本发明,所述锐角在 10。-30。的范围之内, 较佳地选 自以下角度之一: 10。、15。、18。、20。和 22。, 最优选是 20。。 位于主体部 分 21之下的凸出部 23 , 25的第二侧面 232, 252向下朝向头部 211一侧的方向 延伸, 第二侧面 232, 252的延伸方向与正交轴线 Zl , Z2同样形成锐角, 该锐 角在 10°-30°的范围之内, 较佳地选自以下角度之一: 10。、15。、18。、20。和 22。, 最优选是 20° o 可以理解的是, 第二侧面 222, 242也可以被构造成分别向上朝向离开主体 部分的头部 211一侧的方向延伸;第二侧面 232, 252可以被构造成分别向下朝 向离开主体部 分的头部 211一侧的方向延伸。 这样构造的凸啮合件能实现同样 的密封效果 。 凸出部 22, 23的第一侧面 221 , 231为凸啮合件 20与凹啮合件 10啮合时 最先接触凹 啮合件 10的表面, 有利地被构造成便于凸啮合件 20的插入操作。 在所示的本 实施例中, 第一侧面 221 , 231相对于正交轴线 Z1成锐角朝向离开 主体部分 的头部 211一侧与相应的第二侧面 222, 232会聚的方向分别向上或向 下延伸。 由第一侧面 221 , 231限定的头部 211形成锥形头部, 易于插入凹啮合 件 10。 凸出部 24, 25的第一侧面 241 , 251有利地相对于正交轴线 Z2成锐角 朝向离开主体 部分的头部 211一侧与相应的第二侧面 242, 252会聚的方向分别 向上或向下延 伸。由第一侧面 241 , 251限定的主体部分 21的中间部分呈锥形, 也有助于 凸啮合件 20在凹啮合件 10内的推进。 接近凸啮合件 20的头部 211的一对凸出部 22, 23与另一对凸出部 24, 25 可以相同也 可以不同, 只要能够便于凸啮合件 20插入凹啮合件 10和袋式容器 的模制成型 即可。 相应地,凹啮合件 10的形状与凸啮合件 20相匹配以容纳凸啮合件 20并与 之形成紧密密封 式啮合。 图 6A、6B和图 7清楚显示, 凹啮合件 10被构造成包 括分别容纳凸啮合 件 20的凸出部 22, 23 , 24, 25的缺口 12, 13 , 14, 15 , 这 些缺 口 12, 13 , 14, 15也与凹啮合件 10的纵向轴线的正交方向形成在 10°-30° 的范围之 内的锐角, 所形成的锐角与凸出部 22, 23 , 24, 25的第二侧面 222, 232, 242, 252分别相对应。 当凸啮合件 20及其凸出部 22, 23 , 24, 25完全 插入凹啮合件 10形成压紧啮合,使第一容器壳体 1和第二容器壳体 2的顶部互 相密封接合 , 由此实现袋式容器的密封。 凸啮合件 20及其凸出部 22, 23 , 24, 25的形状为本发明的要点之一。 由 于凸出部 22, 23 , 24, 25的第一侧面和第二侧面(尤其是第二侧面)与正交轴 线 Zl , Z2成锐角, 其中所述正交轴线 Zl , Z2与凸啮合件 20的纵向轴线 Y垂 直, 因此凸出部 22, 23 , 24, 25的形状适合于模制成型加工。 同时, 因为凸出 部 22, 23 , 24, 25 的两个侧面的成角度设计而使凸啮合件 20与凹啮合件 10 形成弯折 的匹配压紧啮合, 所述容器中的内容物不会漏出到容器外部 , 而容器 外部的空气 也不容易渗透进入容器内部 , 实现了优异的密封效果。 此外, 凸出 部 22, 23 , 24, 25的两个侧面的形状能够仅通过按压便轻易是密封机构密封闭 合。 现参看图 8A和图 8B, 图中示出根据本发明的第二实施例的袋式容器 的密 封机构。本实施例的密封机构舆上述第 一实施例的密封机构在结构上基 本相同, 主要的不 同之虔在於: 凸啮合件和凹啮合件的主体部分沿其长度方向遵循 曲折 的路径延伸 。 本实施例将波形图案融入到密封机构中, 波浪形状的凸啮合件和 凹啮合件 构造在啮合后保 持了对第一容器壳 体和第二容器壳体 更好的密封锁 定。 具体地, 本实施例的密封机构包括位于第一容器壳体 1上呈波浪形状的凹 啮合件 30和位于第二容器壳体 2上呈波浪形状的 凸啮合件 40。 波形凹啮合件 30和波 形凸啮合件 40分别沿着第一容器壳体 1和第二容器壳体 2的顶部内表 面的整个横 向长度遵循曲折的路径延伸 。 图 10是从图 11所示的 II-II截取的剖 视截面图, 由图中所见,波形凸啮合件 40在与第二容器壳体 2平行的平面中具 有波形横截面 轮廓。 该轮廓由一系列连续交替的峰部 41和谷部 42构成。 每个 峰部 41或谷部 42具有大致等腰三角形轮廓, 该大致三角形轮廓具有直的侧部 43和限定 了波形凸啮合件 40的主体部分的最大高度 的峰部 44。 该等腰三角形 的底和高可 以在 10-30 mm之间, 例如 20 mm。 替换地, 峰部 41和谷部 42可 以分别形成为弧 形峰部和弧形谷部。 相应地, 凹啮合件 30的形状与凸啮合件 40相匹配, 在其与第一容器壳体 1的平 面上的横截面由一系列连续 的峰部 31和谷部 32构成(见图 8B和图 9B)。 这些峰部 31和谷部 32限定了波形轮廓,以容纳波形凸啮合件 40并与之形成紧 密密封式啮合 , 如图 11所示。 根据本发明的第二实施例 的密封机构,凸啮合件 40不仅采用了上述第一实 施例的凸 出部形状, 即凸出部的两个侧面成角度设计, 而且其主体部分做成 “波 形”。 波形设计的优势在于, 凸啮合件的波形主体部分被压入凹啮合件的波形 主体部分 中, 减少了凹凸啮合件之间的移位, 导致二者的密封闭合更好, 并且 产生更高的保 持力。 如图 12A和 12B中所见, 与图 8A和 8B所示实施例类似, 凸啮合件 60在 与第二容器 壳体 2的平面上的横截面由一系列连续 的峰部 61和谷部 62构成。 相应地, 凹啮合件在与第一容器壳体的平面 上的横截面由一系列连续的峰 部和 谷部(未示出)构成。此处的凸啮合件 60与图 8A所示的凸啮合件 40不同之处在 于, 凸啮合件 60的主体部分在包含所述凸啮合件 的纵向轴线 Y且垂直于 第二 容器壳体 2的平面中具有大致三角形轮廓。 如图 12A所示, 所述轮廓具有直的 侧部。 图 12B示出了凸啮合件 60与相应的凹啮合件啮合的截面图。 由于采用 了波形设计, 与现有技术的直线形密封件相比, 波形图案在包含密封件的长度方 向的横向轴线的平面中具有峰部和谷部。如上所述, 这种波形构造对密封效果产生 许多益处。 在图 13 中, 可以从与图 12B相同的视图看到表示又一个实施例的密封机 构的剖视截面 图。此处的凸啮合件 80与图 12A和图 12B所示的凸啮合件 60基 本相同, 都是在与第二容器壳体 2的平面中的横截面由一系列连续的峰部和谷 部(未示出)构成, 但不同之处在于, 凸啮合件 80 的主体部分 81 的外端处设置 头部 82, 所述头部 82与所述主体部分 81形成 T形构件, 在包含所述凸啮合件 的纵向轴线且垂直 于第二容器壳体 2的平面中具有大致 T形轮廓。 为了便于头 部 82插入相应的凹啮合件 70, 所述头部的外侧面做成倒角。 此外, 头部 82的 内侧面相对于 凸啮合件的纵向轴线成锐角延伸, 藉此形成钩部, 与凹啮合件 70 的卡定凸部 71(参照图 12)钩挂, 从而使凸啮合件 80与凹啮合件 70卡合。 同样 地, 凸啮合件 80与凹啮合件 70由于采用了波形设计, 因此提高了二者啮合的 密封效果。 本发明的袋式容器优选地是 由柔性材料制成的柔性容器 。 柔性材料可以是 包含硅胶或 橡胶的材料, 硅胶 (silicone) 是一种无毒性、耐高温、 低温并且易 于模制加工 的聚合物材料。 使用硅胶制成的袋式柔性容器适合于食 品的储存。 特别优选地, 实施例的袋式容器由硅胶模制而 成。 此外, 袋式容器的壁厚可以取决于容器的容积而恰当地 选择。 当容积较大 时, 可以使容器壁具有较大的厚度, 使得容器不会由于内容物的重量过大 而破 裂。 以上通过描述示例性实施例 , 详细说明了本发明的具有密封机构的袋式容 器。 应当理解, 本发明的范围不限于上述实施例, 而是由随附的权利要求所限 定。 在不背离本发明的目标和精神的情况下 , 能够对实施例进行各种修改, 但 是其仍然属于 本发明的范围之内。
