Description

一种设有两道密封环的吹塑瓶螺纹盖
技术领域
本发明属于包装技术领域，主要涉及一种吹塑饮料瓶，特别是设有两道密封环的、具有卫生功能的吹塑瓶螺纹盖。
背景技术
随着吹塑成型技术的成熟和吹塑机的大量使用，吹塑瓶已广泛应用于碳酸饮料、果汁饮料、矿泉水、纯净水、牛奶、豆浆、植物油以及其它液体的盛装。这种吹塑瓶的瓶口普遍采用螺纹盖封口，密封环均位于瓶口顶端，密封环以下的瓶颈外缘，则直接与大气相通。为了防止二次罐装，多在瓶盖下端配有一次性防伪拉环。在生产、运输、储存、使用的各个环节，瓶颈外缘始终与大气相通，无法保证其无菌、无尘的卫生环境，特别是作为饮料瓶直接饮用时，***不可避免地与瓶颈外缘接触，尤其是含糖液体在瓶颈外缘的残留，更容易孳生病菌，由此带来严重的卫生隐患。
如何改进瓶口与瓶盖的结构设计，使瓶颈外缘与外界空气隔绝，长期其保持洁净、无尘、无菌的卫生状态，正是本发明的目的所在。
发明内容
本发明的一种设有两道密封环的吹塑瓶螺纹盖，外观为圆柱体，呈帽状，中空结构，其中在顶端封闭。瓶盖内壁设凸起状螺纹，与之相对应，在瓶颈外缘也设有凸起状螺纹，瓶盖与瓶颈的螺纹相互咬合，实现瓶盖的开启与封合。在瓶盖内侧顶端，设一环状导引环，在封盖时引导瓶口与瓶盖更好地闭合。导引环外缘，是盖顶闭合面，与瓶口顶面紧密闭合构成第一道密封环。在瓶盖内壁的螺纹下方，设置内壁闭合面；与之相对应，在瓶颈外缘的螺纹下方，设置瓶颈闭合面，瓶盖内壁闭合面与瓶颈闭合面紧密闭合，构成第二道密封环。
本发明的一种设有两道密封环的吹塑瓶螺纹盖，其特点是：瓶盖内的盖顶闭合面与内壁闭合面之间的垂直距离，等于瓶口顶面与瓶颈闭合面之间的垂直距离，以保证两道密封环能同时紧密闭合。第一道密封环阻止瓶内液体溢出，第二道密封环阻止外界空气进入。当瓶盖闭合后，使瓶颈外缘处于无尘、无菌的卫生状态。当饮用者的***接触瓶颈时，能够得到相对安全的卫生环境。
本发明的一种设有两道密封环的吹塑瓶螺纹盖，还在瓶盖的下裙部设有撕拉带，撕拉带与瓶盖以点状连接，撕拉带内壁设凸起状的定位环。与之相对应，在瓶颈下部外缘设凸起状止回环。当吹塑瓶罐装液体后，设有撕拉带的、完整的螺纹盖套入瓶口并拧紧，即两道密封环闭合状态下，此时撕拉带内壁的定位环位于瓶颈外缘的止回环下面并且不可逆。首次开瓶时，瓶盖沿螺纹上提，撕拉带受止回环限制，使之与瓶盖主体分离，表明该瓶已经开启，有效地防止二次罐装，保证消费者身心健康。
本发明提供的一种设有两道密封环的吹塑瓶螺纹盖，使瓶体在罐装、储存、运输、销售的各个环节，都能保证瓶颈外缘始终处于相对无尘、无菌的卫生环境中，为方便消费者直接用***饮用提供了安全保证。
本发明结构新颖，工艺简单，应用广泛，不增加生产成本，专利成果易转化。

具体实施方式
图3是本发明提供的具体实施方式，设有两道密封环的吹塑瓶螺纹盖与瓶颈配合使用的示意图。
在本实施例中，吹塑瓶螺纹盖的外观为圆柱体，中空帽状结构，顶端封闭。瓶盖内壁设两道凸起状螺纹，即瓶盖内壁第一道螺纹[1]和瓶盖内壁第二道螺纹[2]；与之相对应，在瓶颈外缘也设有两道凸起状螺纹，即瓶颈外缘第一道螺纹[11]和瓶颈外缘第二道螺纹[12]，螺纹[1]与螺纹[11]咬合，螺纹[2]与螺纹[12]咬合，实现瓶盖的开启与封合。
在瓶盖内侧顶端，设一环状导引环[3]，在封盖时引导瓶口与瓶盖更好地闭合。导引环外缘，是盖顶闭合面[4]，与瓶口顶面[14]紧密闭合构成第一道密封环。在瓶盖内壁的螺纹下方，设置内壁闭合面[8]；与之相对应，在瓶颈外缘的螺纹下方，设置瓶颈闭合面[18]，瓶盖内壁闭合面[8]与瓶颈闭合面[18]紧密闭合，构成第二道密封环。瓶盖内的盖顶闭合面[4]与内壁闭合面[8]之间的垂直距离，等于瓶口顶面[14]与瓶颈闭合面[18]之间的垂直距离，以保证两道密封环能同时紧密闭合。第一道密封环阻止瓶内液体溢出，第二道密封环阻止外界空气进入。瓶盖闭合后，瓶颈外缘处于相对无尘、无菌的卫生状态，为饮用者直接以***接触瓶颈提供相对安全、卫生的环境。
本实施例还在瓶盖的下裙部设有撕拉带[5]，与瓶盖在[7]处以点状连接。撕拉带[5]内壁设凸起状的定位环[6]，与之相对应，在瓶颈下部外缘设凸起状止回环[16]。当吹塑瓶罐装液体后，设有撕拉带的瓶盖套入瓶口并拧紧，即两道密封环闭合状态下，此时撕拉带内壁的定位环[6]位于瓶颈外缘的止回环[16]下面，并且不可逆。首次开瓶时，瓶盖沿螺纹上提，撕拉带[5]受止回环[16]限制，使之与瓶盖主体分离，用以防止二次罐装。
本发明提供的一种设有两道密封环的吹塑瓶螺纹盖，在瓶体罐装、储存、运输、销售的各个环节，都能保证瓶颈外缘始终处于相对无尘、无菌的卫生环境中，为方便消费者直接用***饮用提供了安全、卫生保证。
