Description

具有衬里密封排气孔的封盖
本发明涉及在封盖外壳内的压塑密封衬里，更具体地说，涉及用于给压塑模腔排气，以防在衬里中形成气泡。
发明背景和概述
用于许多类型饮料、食品、果汁、药物及类似应用的塑料封盖包括塑料外壳，所述外壳有一唇边，该唇边在邻近封盖外壳底壁并与所述外壳底壁的内侧表面间隔开的位置处从封盖侧缘径向上向内延伸。密封衬里在封盖底壁的内侧表面上原位压塑，同时唇边与压塑工具协同工作以便形成模腔。美国专利4984703和6660349示出这种类型的封盖。提出在衬里压塑工具中提供排气通道，以便当模制衬里时排出模腔中空气。然而，衬里压塑工具中的通道可能变堵塞或阻塞，同时妨碍模腔的合适排气并导致在衬里中夹带气泡。这也不希望有地增加了生产废品率并因此增加了生产封盖的成本。本发明的一般目的是提供一种封盖，其中衬里压塑模腔穿过封盖外壳排气而不是穿过模制工具排气，因而增加了从模腔中排气，同时减少或消除了在衬里中夹带气泡，并降低了封盖废品率和生产成本。
按照本发明一个方面所述的封盖外壳包括底壁、唇边、和至少一个通道，上述底壁具有用于固定到容器成品上的侧缘，上述唇边在邻近底壁并与所述底壁间隔开的位置处从侧缘径向上向内延伸，而上述通道贯穿唇边。在本发明的优选实施例中，通道取沟槽的形式，所述沟槽在唇边的径向上内边缘处和轴向上间隔开的表面处开口。沟槽优选的是具有一径向上向内的端面表面，所述端面表面在轴向上远离底壁和从侧缘径向上向内形成角度。唇边优选的是有一在轴向上面向远离底壁的表面，同时至少邻近径向上内边缘的部分是平坦的且垂直于侧缘的轴线。沟槽优选的是在轴向上面向唇边表面的这个平坦部分处开口。
按照本发明的优选实施例另一方面所述的塑料封盖包括外壳上述外壳具有底壁和唇边，上述底壁带有侧缘用于固定到容器成品上，而上述唇边在邻近底壁并与所述底壁间隔开的位置处从侧缘径向上向内延伸。衬里是贴着底壁并在底壁和唇边之间原位压塑。唇边有多个在圆周上间隔开的通道，所述通道贯穿唇边，用于在压塑衬里期间排气。
附图简介
本发明与其另外一些目的、特点、优点和方面一起从下面说明、所附权利要求及附图将最好理解，其中：
图1是包括按照本发明一个优选实施例所述的容器和封盖的包装的透视图；
图2是图1的包装中封盖的局部剖视图；
图3是在图1和2的封盖中模制封盖外壳的局部剖视的正视图；
图4是基本上沿着图3中线段4-4所取的局部剖视图；和
图5是示出用于压塑图3-4封盖外壳中衬里的工具的局部示意图。
优选实施例详细说明
图1示出一种包装10包括容器12和塑料封盖14，上述容器12用玻璃或塑料制成，而上述塑料封盖14固定到容器12成品上。封盖14优选的是利用封盖14上的一个或多个内螺纹(或螺纹段)与容器12成品上的一个或多个外螺纹(或螺纹段)啮合固定到容器12上。
图2示出按照本发明一个优选实施例所述的塑料封盖14包括塑料盖或外壳16和塑料衬里18，所述塑料衬里18原位压塑在外壳16内。外壳16包括底壁20和周边侧缘22，所述周边侧缘22有一个或多个内螺纹(或螺纹段)23(图3)用于将封盖固定到容器12成品上(图1)。圆周上连续的环形唇边24邻近底壁20但与所述底壁20轴向上间隔开从侧缘22径向上向内整体延伸。唇边24有一内表面26，亦即面向底壁20相对的内表面，成锐角设置到底壁20上。具体地说，在优选实施例中，表面26包括第一锥形表面部分28和第二锥形表面部分30，上述第一锥形表面部分28邻近侧缘22与底壁20成第一锐角，而上述第二锥形表面部分30从表面部分28与底壁20成第二锐角延伸。边缘32形成第三表面34与底壁成第三锐角。唇边24有一表面38面向在轴向上远离底壁20。该表面38优选的是包括第一部分40和第二径向上外面部分42，上述第一部分40邻近唇边24的径向上内边缘，该唇边24的径向上内边缘平坦而垂直于封盖侧缘22的轴线(亦即在外壳模制工具的容隙内垂直)，而上述第二径向上外面部分42与封盖侧缘的轴线成一角度。在本发明用于38mm成品的一个示例性实施例中，表面部分28成45°角，表面部分30成10°角，表面部分34成72°角，和表面部分42成60°角，上述角度全都是与侧缘22的中心轴线所成的角度。
成角度间隔开的若干排气孔的圆周阵列贯穿唇边24。这些排气孔优选的是取狭槽或沟槽44的形式，上述狭槽或沟槽44在唇边24的径向上内边缘处，及在唇边24的上表面和下表面处开口。沟槽44有一与封盖侧缘的轴线成一定角度的径向上向内的端面表面46。表面46在所示实施例中是一种组合表面，它有第一部分48和第二部分50，上述第一部分48邻近侧缘22与侧缘轴线成第一角度，而上述第二部分50与侧缘轴线成第二更大角度延伸到唇边表面40。表面部分50的角度控制排气孔的深度和排气流速。表面部分48的角度用于工具设计目的，并可与表面部分50的角度相同。在本发明的示例性实施例中，表面部分48与封盖轴线15.5°角，而表面部分50与封盖轴线成27.5°角。表面40的上端优选的是在封盖侧缘22的内侧表面处，而表面50的下表面优选的是唇边表面部分40和42的接合处。(方向词语如“上”和“下”作为说明应用，并且不限于图2-4所示的封盖和外壳的直立取向。方向词语如“轴向”和“径向”作为说明应用，并且不限于封盖侧缘22的中心轴线。所有示例性尺寸和角度都是标称词)。在本发明的示例性实施例中，有12个等间距围绕唇边24的排气沟槽，每个沟槽宽约0.025英寸。排气狭槽44优选的是在注塑或压塑封盖外壳期间模制到唇边24中。作为可供选择的方案，排气沟槽44可以在模制后操作时在唇边24中刻槽或用别的方法形成。
密封衬里18贴着底壁20，并在底壁20和唇边24之间原位压塑。衬里18可以具有任何合适的构造，如在下述美国专利4984703，5306542，6371318，6399170和6660349其中任一个所公开的。图5是用于在外壳16内压塑衬里18的工具60的示意图。这种工具优选的是包括衬里尖头62，所述衬里尖头62滑动式安装在套筒组件64内。套筒组件64优选的是包括内套筒66和外套筒68，所述内套筒66和外套筒68与尖头62和封盖外壳16一起形成用于压塑衬里18的模腔70。排气沟槽72设置在套筒66、68之间。套筒68的下端面(按图5取向)接合唇边表面部分40和唇边24的径向上内边缘，以便闭合模腔70。唇边24中的排气沟槽44通向套筒68的下端面。在模制衬里18期间，将衬里材料的装料在退回模制工具60的情况下放在外壳16内。然后将模制工具移到外壳中，同时使套筒66，68进入图5所示的位置。然后将衬里尖头62进一步移入到外壳中，以便压缩衬里材料的装料，并使衬里材料向外流向模腔70的周围。被这个材料流置换出的空气可以穿过沟槽44并围绕套筒68径向上向外排气，以防在衬里内夹带空气形成气囊或气泡。
这样公开了封盖外壳、塑料封盖、及制造塑料外壳和封盖的方法，上述塑料外壳和封盖完全满足上述所有目的和目标。本发明与其优选实施例一起公开，并论述了许多修改和变动。对该技术的技术人员来说，根据上述说明很容易在心中浮现其它的修改和变动。例如，本发明的原理与冷的软饮料封盖一起示出，所述软饮料封盖在侧缘的边缘处的螺纹和夯实带中有排气槽；然而，本发明决不是限制这种类型的封盖。本发明打算包括所有这些修改和变动，因为它们属于所附权利要求的精神和很宽阔的范围内。
