一种具有活动铰链的自干燥容器,其包括由树脂粘结的吸着剂制成的容器主体和至少一个附接部件,以及具有与所述容器主体接合以闭合所述主体的封闭部分的容器封闭件和与所述容器主体上的附接部件相配的用于将所述封闭件固定至所述主体的附接部件,以及将所述封闭件部分连接至所述附接部件的活动铰链。
Description
技术领域
本发明大体涉及用于食物、药物和其他物品的容器,且更具体地涉及这样的容器,其防止湿气的进入,减少包装中的湿气含量,并且具有用活动铰链附接至容器的封闭件。
背景技术
活动铰链最常见的是树脂基铰链,它们通常相对薄且是柔性的,其将容器的两个刚性或半刚性部分连接在一起,从而允许它们沿铰链的线弯曲。便利地,活动铰链在喷射模塑操作中被制造,所述操作同时产生了所述铰链和连接至所述铰链相应侧的两个包装部件。活动铰链便于减少使用它们的物件的价格且具有相对长的寿命。
在制药和食品包装容器,以及其他容器中,人们总是希望将封闭元件附接至闭合的包装以使得其不被移位且便于容易地打开和关闭闭合所述包装。活动铰链提供了方便的方式去实现这些且用于各种这样的包装。
在用于因包装中存在额外湿气含量而变质的食品和药物以及其他物品的包装中,人们希望提供一种由提供干燥功能的材料制成的包装,即,一种包括能使得材料本身来吸收水蒸汽并减少包装中的湿气成分的材料。所述材料大体是已知的,并且所描述的包装类型已经在过去提供过。
迄今为止,吸湿塑料材料的成分与使用这些材料以提供活动铰链并不相符。为了吸收有用量的湿气,用于形成容器的塑料和其他树脂必须包含高百分比的添加剂,诸如干燥材料。在量上足以提供适当的干燥功能的干燥材料的存在改变了所述塑性材料的特征。所述材料的柔性变差且倾向于张紧和挠曲疲劳且当重复受力时最终破损,所述重复受力是制造所述活动铰链的材料所必须的。
所以,具有活动铰链的干燥包装不能由一种单一的材料制成并且仍然提供适当的活动铰链和适当的干燥功能。
本发明的目的在于提供具有活动铰链的干燥容器,其解决迄今为止已知的容器的缺陷。
发明内容
简要地说,具有活动铰链的自干燥容器包括由树脂粘结吸着剂制成的容器主体,以及至少一个附接部件,以及容器封闭件,所述容器封闭件具有与容器主体接合以闭合所述主体的封闭部分和与所述容器主体上的附接部件相配的用于将所述封闭件固定至所述主体的附接部件,以及将所述封闭部分连接至所述附接部件的活动铰链。
根据本发明的另一方面,所述容器的主体和所述容器封闭件的特征在于具有第一和第二不同的弯曲模,所述封闭件的弯曲模大于所述容器的弯曲模。
根据本发明的另一方面,所述容器主体包括高密度聚乙烯。
根据本发明的另一方面,所述容器主体包括聚丙烯。
根据本发明的另一方面,所述容器主体包括按重量计在约5%至约50%之间,优选约30%的干燥剂,所述干燥剂选自由胶或筛、粘土、氧化钙或碳组成的组。
根据本发明的另一方面,所述容器主体和容器颜色不同。
根据本发明的另一方面,所述树脂粘结吸着剂包括树脂粘结干燥剂。

附图说明
本发明的新颖的方面特别地在所附权利要求中阐述。结合附图参考本发明优选实施例的下面详细描述将更容易理解本发明以及其进一步目的和优势:
图1和图2是从不同角度观看的根据本发明的容器的立体图;
图3是分开示出容器主体和容器封闭件的立体图;
图4和图5是示出了容器封闭件被组装至容器主体的立体图;
图6是示出了容器主体和容器封闭件的立体图,所述容器封闭件具有对应的孔和突出部以使容器封闭件固定在容器主体上;
图7A和图7B是根据本发明的另一个实施例通过两口(shot)喷射模塑的容器的侧视图。
具体实施方式
现在参照图1,以立体图示意出了根据本发明的容器。总体由10表示的所述容器包括容器主体12和容器封闭件14,所述容器封闭件具有盖和组装在主体上的附接部件18。活动铰链16连接在盖24和附接部件18之间。所述活动铰链16优选地具有附接至封闭盖24和附接部件18的较厚部分28、30和在所述较厚部分之间的较薄铰链部分。
优选地,所述封闭件14、所述活动铰链16和所述附接部件18由树脂材料制造,树脂材料诸如聚乙烯、聚丙烯或者具有适于制作活动铰链的特征的其他聚合物。所述容器主体12优选地由诸如高密度聚乙烯或聚丙烯的聚合物,或者具有低的水蒸气透过率的其他聚合物材料来制造。干燥剂诸如硅胶、筛、粘土、氧化钙或碳在聚合物中的含量在约5%和50%之间,优选地约30%。代替或者除了所述干燥剂,可包括去氧剂诸如铁基去氧剂。当在特殊应用中有用时也可以包括有香味的树脂或胶。
图3分别示出了所述容器主体12和所述封闭件14。所述主体12大体是圆柱形的。根据本发明的一个实施例,所述主体12从在基部20的较小直径到在开口端22的略大直径呈锥形。所述主体的开口端可以具有稍微向外延伸的唇部26。所述封闭件14具有盖24,所述盖优选地咬合住所述主体12的开口端22,也许接合所述唇部26,以及具有环形式的环状附接部件18,所述环具有内表面19,所述内表面19优选地呈锥形以匹配所述主体12的锥度。所述盖24和所述附接构件18被活动铰链16连接,所述活动铰链具有两个厚部分28、30,所述厚部分被较薄的活动铰链部分连接,所述较薄的活动铰链部分具有约为0.2-0.3mm的较小厚度。所述较厚部分28、30分别被连接至所述盖24和所述附接部件18。所述活动铰链16的准确形式并不局限本发明所述,可以使用任何已知的活动铰链构造。所述尺寸仅是示例性的且取决于材料和其他因素是可变的。
优选地,所述封闭件14由纯聚合物形成,即,没有干燥或吸氧添加剂的聚合物。优选地是当所述附接部件18滑进靠近所述开口端22的最终位置时,所述附接部件18合适地装配在所述容器主体12上。所述封闭件14可以由聚乙烯或聚丙烯或其他聚合材料制成。
图4和图5示出了所述容器封闭件14是如何放置在所述容器主体12上的。如图4所示,所述封闭件14滑过所述主体12的封闭端20上方,以及如图5所示,所述封闭件14向上朝着其固定配合的较大开口端22滑动。优选地,所述容器主体12是锥形的且所述附接部件18的内表面具有相配的锥度。
图6示出了本发明的另一个实施例,其中所述容器主体30包括多个突出部32,每个突出部优选地但不一定具有锥形的或三角形截面,且与所述容器主体30的上开口端44相邻设置的周向环状环34间隔一小段距离。所述对应的容器封闭件40包括与所述容器主体的所述开口上端44接合的封闭件盖部分42以及具有环状带46形式的附接部件,所述环状带46具有多个形成在其内的孔48,所述孔48的间隔和尺寸设置成与所述容器主体30上的类似多个突出部32接合。在示意的实施例中,所述孔48大致具有矩形的截面。可以理解的是突出部可以比孔的数量少。活动铰链50将所述容器密封盖部分42与所述附接部件或边46连接。所述容器主体30和容器封闭件40由图1至图5中所提到的对应元件的材料制成。
虽然本发明可以如上所述的根据本发明的另一个实施例形成为两部分,但是所述容器通过使用两口模塑工艺模塑为单个工件。参照图7A和图7B,所述容器10的底部部分12通过利用塑料材料填充模具的一部分而形成,所述塑性材料的类型已经描述过,其包括干燥剂且不将该部分硫化或从模具移除,所述容器的上部部分18和盖14使用已经讨论过的不具备干燥剂添加剂的类型的塑料材料被喷射进模塑腔。用于所述两个喷射部件的所述塑料材料可以选择成使得它们是相配的,也就是说,它们可以产生单个的基本上连续的材料主体,其在下部部分具有添加剂,但是在上部部分和盖不具有添加剂。可选地,所述盖14也可以仅仅在铰链部分16具有干燥剂添加剂但在三口模塑过程中不具有添加剂。
虽然本发明已经关于目前其优选的一些实施例被描述,但本领域技术人员可以获知这些实施例的不同的变型和变化,且期望的是权利要求的本发明包括了这种变型和变化。例如,主体可以有不同的形状和尺寸,诸如圆形、椭圆形、正方形等等。虽然已经描述了突出部和孔的具体布置,但其他咬合布置,诸如在环状构件上的凹槽而不是孔,也是可使用的。
此外,容器主体上的附接部件和容器封闭件上的附接部件是可以通过焊接、胶合或类似的方式连接在一起的部件。虽然示出的本发明具有在容器主体上的突出部和在环状环上的孔,但是该布置可以颠倒使得在容器主体上具有孔而在环状环上具有突出部。
所述材料可以选择成使得它们能够通过热或超声波被相互焊接。所述容器主体和顶部也可以由不同的材料共同挤压而成。
所述盖自身可以包括明显改动部件和/或咬合或锁定类型的封闭件。
所述容器主体、顶部、或者两者都可以被涂色以区分在所述容器主体中干燥剂和/或吸氧剂和/或其他吸收剂的类型和能力。
申请人已经发现干燥剂或吸氧剂在容器主体中的存在可以改进主体的特征,也就是弯曲和收缩特征。
虽然聚丙烯是湿气的有效屏障,但它并不优选来制造所述容器主体因为它具有高的弯曲和收缩特征。当相同的材料根据本发明被提供有干燥材料时,其弯曲和收缩特征会被显著改进。
如已经讨论的,所述容器主体可以具有水蒸汽吸收材料,吸氧材料,气味吸收材料,有气味的材料,或这些材料的两种或多种的组合。
根据本发明制造的容器在药物领域是有用的,用来包装诊断测试条带,如助听器包装,以及用于快餐和/或糖果应用,以及任何其他需要从包装中去除湿气的食物应用。
