Abstract

一种弹性的可用于微波中的容器(10)包括一个盆(12)和一个可有选择地打开的压合盖(14)。盖包括多个压合在从盆向外延伸的一对环形法兰(80、82)上的凸起件(84)，由此可以听到证实盖已装好的“卡搭”声。

Description

具有压合的可有选择地打开的盖的容器
技术领域
本发明关于用来储存和传送如食品类物品的容器，特别是关于一种容器，它包括一个盆、和一个压合的、可有选择地打开的盖。
先有技术的描述
容器、特别是用于在微波炉中再加热食品的容器应该是成本比较低，而且使用方便。另外，这种容器应该是多用途的，亦即它们能经受得住各种不同的环境，例如将容器从冰箱或冷冻器直接送入微波炉那样出现的环境。
关于这种用于微波中的容器，先有技术中的关键问题在于在盖和盆之间提供良好的密封，很少注意到盖和盆之间连接的机械整体性。另外，现有的市场上的用于微波中的容器在盖和盆密封啮合时不能听到响声。
本发明的公开
因此，本发明的目的在于提供一种容器，它包括一个盆和一个可有选择地打开的盖，该盖包括易于安装和打开的密封件。
本发明的另一个目的在于提供一种低成本的、由弹性材料制成的高生产率的容器。
本发明还有一个目的在于提供一种容器，它在盖装到盆上时提供响声，从而指示已产生了良好的密封。
本发明还有一个目的在于提供一个盖，该盖可阻止它从盆上非故意的打开。
本发明的又一个目的在于提供一个弹性的容器，它可用于如冰箱和微波炉的各种环境中。
按照本发明的教导，提供一种可用于微波中的容器，它包括一个盆和一个可有选择地打开的盖，每个均具有向外延伸的边。盆和盖边具有至少一个、最好为多个凸件和法兰，法兰在盖装在盆上和从盆上打开时以可产生“卡搭”声的方式相互滑动啮合，以证明容器已密封了。凸件与法兰的配合在密封状态时能抵抗盖从盆上非故意的打开。在一个实施例中，盆边包括至少一个基本为环形的向外延伸的法兰，盖边具有至少一个向内延伸的凸起件。在另一个实施例中，盆边包括至少一个向外延伸的凸起件，而盖边包括至少一个向内延伸的法兰。
可以用下列任何一种已知的热塑性树脂来很经济地热成形本发明的容器，这类树脂包括、但不仅限于下列树脂：聚酰胺、聚丙烯、聚丙烯酸酯、聚碳酸酯、聚酯、聚醚酰亚胺、聚醚酮、聚烯烃、聚亚苯基、聚氯乙烯、和各种苯乙烯和液晶高分子聚合物。
从下面参照附图的描述可更清楚本发明的特征、目的和优点。
附图概述
图1是按本发明的教导制成的容器的打开时的透视图，
图2是沿图1中2-2线的容器打开时的剖视图，
图3是该容器组装后的剖视图，
图4是按本发明的教导制成的容器的打开时的透视图，
图5是沿图4的5-5线的容器打开时的剖视图。
实施本发明的模式
现参见图1，它示出一个容器10，该容器包括按照本发明教导的一个盆12和可有选择地打开的盖14。从外观上看可以注意到，该容器通常是圆的，但该容器也可是如椭圆形、长方形或方形的各种其它构形的。
盆12通常包括底16和连续的侧壁18，该侧壁从底垂直延伸以限定盆腔88。整体连接到垂直延伸的侧壁上的是基本为L形的连续的边20，该边20包括从侧壁朝外延伸的第一腿部24和从第一腿部向下延伸的第二腿部26。连续的边的第二腿部26包括一对离开的、向外延伸的、基本为环形的法兰80和82。这里“基本为环形”指的是法兰80和82应围绕着第二腿部的主体延伸，然而法兰不必是连续的。
正如从图3可更清楚地看出的，侧壁18的上部22最好包括向内延伸的环形凸块28，它有助于盖和盆之间的牢固的啮合，这一点下面将详细描述。
盖14通常包括一个具有周边32的本体30，在安装时，边32叠合在盆边20的一部分上。边32通常具有倒U形的截面，它包括从本体伸出的第一腿部34，第二腿部36和位于它们之间的如图3所示的腹板38。从边32的第二腿部36向内延伸的是多个圆周的隔开的凸起件84。该凸起件84通常安置在第二腿部36的终端边缘86附近，它最好是圆的，从而可减小将盖从盆上打开时所要求的分离力。凸起件的数量至少有10个、最好有20个。如图所示，这些凸起件84最好沿边32等间隔地分布。
在将盖14连到盆上时，凸起件84压在环形法兰80和82的上方，由此使盖固定到盆上。当凸起件压在环形法兰上时，压合作用提供了特殊的“卡搭声”它提供一个声响指示，即盖、盆之间的内合密封已经完成。这里所谓的内合密封是在边32的第一腿部34前进到环形凸块28的上方，如图3所示，密封点啮合侧壁18的内表面。
在密封边32的安装点提供了抗弯曲的刚性突出构件40，它从第二腿部36向外延伸。图示的基本为三角形的突出构件40包括板部42和周边缘44。板部42具有多个隔开的向上的凸棱46，第一凸棱50沿构件的纵向中心线48设置，第二和第三凸棱52和54分别安置在第一凸棱的相对侧，它们与纵向中心线48成一角度延伸。每个凸棱均有相当陡的边缘，这就进一步增大了突出构件的结构刚度。
凸棱的位置位于使突出构件的刚度最大的特殊位置，此位置增强了来自突出构件的分离力向密封区的传递、亦即在需要时增大了盖从盆上的可释放性。例如，第一棱50包括相对于板的第一横向边缘，该边缘与纵向中心线呈3°～7°之间的角上延伸，还包括第二横向边缘，该边缘与纵向中心线约呈3°～7°之间的角度上延伸，因此，该第一凸棱通常为梯形的。
第二凸棱52包括与纵向中心线48约呈8°～12°之间的角上延伸的第一横向边缘和与纵向中心线约呈20°～40°之间的一个角上延伸的第二横向边缘。第三凸棱与上述第二凸棱是镜像关系，它在-8°～-12°的一个角上沿第一横向边缘延伸，并在与纵向中心线呈-20°～-40°的角上沿第二横向边缘延伸。因此，正如图示和参照优选角度方向描述的，第二和第三凸棱与纵向中心线呈角度地延伸，并基本为三角形。
应该看到，相对于纵向中心线的负角度(-°)用来清楚表明并强调第二和第三凸棱呈相互镜像关系。对此，一个本专业技术人员应很容易看到，例如-3°则相当于用标准角度表示的357°，-7°相当于353°。
按照一个优选实施例，每个向上立起的凸棱包括终止在边32附近的第一端70和终止在突出构件外边缘44附近的第二端72。向上立起的凸棱通常从第二端向第一端向上倾斜，平均倾斜角度在12°～18°之间，这样使凸棱在腹板和第二腿部36之间的连接点附近连接到边32上。突出构件周边缘最好包括向下卷边的法兰74，它在板42下方延伸，从而提供一个防止用户的大拇指或手指从突出件滑脱的障碍物。
为了从盆上取下盖，用户向上拉动突出构件40，以破坏内合密封。当盖拉到离开盆时，凸起件84拉到法兰80和82的上方，因此可听到盖子安装时听到的那样的“卡搭声”。
现参见图4，它示出容器10的替换的实施例，按照该实施例，一系列的凸起件84a安置在盆边20的第二腿部26上，基本为环形的法兰80a和82a从盖边32的第二腿部36向内延伸，因此，法兰80a和82a分别压合在凸起件84a上，这样在盖和盆安装和打开时就可听到清脆的“卡搭”声。在其它方面，该容器最好与图1～3所示的相同。
从前面的描述应该看出，盖和盆组件形成的容器对盖从盆上在不需要的时候打开时具有很大的机械阻力。然而，由环形法兰和凸起件提供的机械阻力基本不会增加需要打破内合密封、将盖从盆上打开时的分离力。另外，在将盖装到盆上时可清晰地听到的“卡搭”声，为用户清楚地指示零件之间的密封关系已完成。
如上所述，盖和盆可用热成形式的多种聚合材料的任何一种制成，有选择地包含增滑剂的聚丙烯均聚物被认为是可优选的。由于采用聚丙烯均聚物，盖和盆可热成形成厚度约在10～50密耳之间，还可具有必要的结构整体性。
显然，本发明公开的优选实施例可完成所述的目的，应该看到，可对本发明进行修改、变化和改变，这将不超出本发明的精神。
工业实用性：
这些容器可在低成本下制成，从而提供在使用后再重复使用的经济的储物容器。
