Abstract
本发明涉及一种密封塑料瓶,包括瓶体,瓶体顶端设置有瓶盖,其底端设置有瓶底,瓶身顶端处为塞体,瓶身圆周为若干褶皱单元组成的褶皱结构,褶皱单元间的间距相等,且上褶皱可套设在下褶皱内,瓶身采用半透明的塑料材料制成,所述瓶盖上设有排气孔和固定件,固定件与瓶盖之间设置有可绕固定件水平旋转且能遮盖排气孔的挡板。采用上述结构后,瓶盖上设置有排气孔和可旋转的挡板,在瓶身上的上褶皱套在下褶皱的过程中就可将瓶体内的空气通过瓶盖上的排气孔排出瓶体外部,再将挡板挡住排气孔将瓶体内部与外部隔离开,保证瓶体内无空气存留,瓶体内物质可以存放更长的时间。
Description
技术领域
本发明涉及一种塑料制品,尤其是涉及一种密封塑料瓶。
背景技术
现有塑料瓶的密封是一次性的,通过顶部设置的瓶盖密封,一旦瓶盖开启后,瓶中剩余物质就与空气接触,再次将瓶盖盖上也有空气存留在饮料瓶中与瓶中物质长时间接触,导致物质的保存时间较短,很容易变质。
发明内容
为了克服上述缺陷,本发明提供了一种密封塑料瓶。
本发明解决其技术问题所采用的技术方案是:一种密封塑料瓶,包括瓶体,瓶体顶端设置有瓶盖,其底端设置有瓶底,瓶身顶端处为塞体,所述瓶身圆周为若干褶皱单元组成的褶皱结构,所述褶皱单元间的间距相等,且上褶皱可套设在下褶皱内,所述瓶身采用半透明的塑料材料制成,所述瓶盖上设有排气孔和固定件,所述固定件与瓶盖之间设置有可绕固定件水平旋转且能遮盖排气孔的挡板。
本发明的有益效果是:采用上述结构后,瓶盖上设置有排气孔和可旋转的挡板,在瓶身上的上褶皱套在下褶皱的过程中就可将瓶体内的空气通过瓶盖上的排气孔排出瓶体外部,再将挡板挡住排气孔将瓶体内部与外部隔离开,保证瓶体内无空气存留,瓶体内物质可以存放更长的时间。
附图说明
图1是本发明结构示意图。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
如图1所示一种密封塑料瓶,包括瓶体1,瓶体1顶端设置有瓶盖2,其底端设置有瓶底3,瓶身1顶端处为塞体4,瓶身1圆周为若干褶皱单元组成的褶皱结构5,褶皱单元间的间距相等,且上褶皱可套设在下褶皱内,瓶身1采用半透明的塑料材料制成,瓶盖2上设有排气孔6和固定件7,固定件7与瓶盖2之间设置有可绕固定件水平旋转且能遮盖排气孔的挡板8。
瓶盖上设置有排气孔和可旋转的挡板,在瓶身上的上褶皱套在下褶皱的过程中就可将瓶体内的空气通过瓶盖上的排气孔排出瓶体外部,再将挡板挡住排气孔将瓶体内部与外部隔离开,保证瓶体内无空气存留,瓶体内物质可以存放更长的时间。
需要强调的是:以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
