一种气压式挤出容器以及产品灌装和挤出方法 技术领域
本发明涉及一种气压式挤出容器以及产品灌装和挤出方法。 背景技术
现有技术中的产品包装袋或包装盒等包装容器， 大致可以分为两类； 一类是以包装袋为 代表的软性材质包装容器， 其虽然使用后期挤出程度较小 （即废弃时包装袋内残留的产品量 少），但其存在储存和运输时易破损并且使用时随着产品的减少变小而造成外观不雅； 另一类 是以包装盒为代理的硬质材料制成的包装容器， 其虽然避免了包装袋在储存、 运输和使用时 的不足， 但受限于其变形程度差的限制， 其在废弃时残留的产品余量却明显增大， 虽然现有 技术中通过将出口设置在底部以利用重力作用在一定程度上克服了这一缺陷， 但其仍存在残 余严重的问题。
产品的残留不单单是消费者损失金钱的问题， 在人们环境保护意识越来越高的今天， 其 更带来了后续环境处理的成本和工艺复杂程序的增加； 此处， 对于某些特定的产品来说， 以 上两种包装容器不能避光或者避免空气进入容器中也是一个很大的问题， 这可能会对产品的 性能和保质期产生不良影响。
如何开发出一种既可以大幅度减少废弃时的产品浪费、 提高使用效率、 降低后续废物处 理的成本和工艺复杂程度， 并且可以对储存的产品进入避光、 避免空气进入且运输和储存时 安全， 使用时美观的包装容器， 是本领域亟待解决的问题。 发明内容
本发明的目的在于提供一种能大幅度减少废弃时产品残留、 运输储存安全且使用时不影 响整体产品美观度的气压式挤出容器以及产品灌装和挤出方法。
为了达到上述目的， 本发明所采用的方案为：

加压装置用于增加间隙空间中的气体压力， 其可以通过向间隙空间中补充额外的气体而 增加压力， 或者压缩间隙空间体积而增加压力， 亦或可以两者兼而有之； 从而使容置部在气 压的作用下被挤压而将其内部盛装的产品挤出。 使用时， 使出口转动或打开至允许产品挤出 的打开状态， 启用加压装置或对其施加作用力， 间隙空间中的气压增加； 从而对可压缩性的 软质材料制成的容置部施加压力， 容置部被挤压， 其内盛装的物料或产品从出口被挤出； 待 挤出所需要量的产品后，停止加压装置或撤去施加于作用力上的力， 间隙空间中的压力停止， 出料停止。 当需要大量的产品时， 可以分次按上述操作分别挤出。
该容器通过将传统的包装容器改为双层结构， 内层采用可压缩性的软质材料制成的容置 部对产品进行直接盛装， 由于其物理特性可以实现产品的方便挤出和极低的残留量； 同时通 过外部的壳体避免单纯容置部而造成的易破损和使用时不美观； 并且挤出操作是通过对两者 间的间隙空间中的气压增加的方式来对容置部进行作用而挤出产品， 使用方便、 快捷。

所述产品挤出的步骤包括：
S21 产品挤出的步骤， 通过加压装置施加压力使容置部与壳体之间的间隙空间中的 气压增加， 间隙空间中的气体进一步将压力传导至容置部表面， 使容置部内的产品被挤压而 经出口被挤出；
S22 状态恢复的步骤， 加压装置停止施加压力后， 产品挤出停止， 容置部的单向出 口关闭以避免空气进入容置部， 加压装置回复到初始状态以备下次使用。
下次挤出或需要多次挤出时， 重复上述 S21和 S22步骤。
该方法通过将产品灌装到双层结构容器的内层中，并且内层采用可压缩性软质材料制成， 由于其物理特性可以实现产品的方便挤出和极低的残留量； 同时通过外部的壳体避免单纯容 置部而造成的易破损和使用时不美观； 并且挤出操作是通过对两者间的间隙空间中的气压增 加的方式来对容置部进行作用而挤出产品， 使用方便、 快捷。

具体实施方式
为了使本领域技术人员可以更好地理解本发明， 从而对本发明的保护范围作出更清楚的 限制， 下面结合附图对本发明的结构和方法进行详细描述。
如图 1、 2所示， 一种气压式挤出容器， 其由容置部 1、 壳体 2和加压装置组成， 容置部 1内部具有用于盛装产品的容置空间 11， 其盛装的产品可以是固体、 液体或膏状物； 所述容 置部 1至少具有一个用于产品挤出的出口 12， 根据产品或使用场景的特殊需要， 出口 12也 可以设置为多个出口或是多个细小孔组成的集群式开口； 显然， 容置部 1也可以还包括用于 将产品灌装到容置部 1中的灌装口或者现有技术中可以实现将产品灌装到其中的其他方式， 也包括现有技术中存在的为实现灌装目的的容置部结构。 所述容置部 1设置于壳体 2内部， 壳体 2上设有与容置部 1对应位置设有开口 21供容置部 1的物料出口 12穿出以使其内的产 品可以被挤出， 壳体 2在与容置部 1配合后开口 21处为密封结构； 容置部 1与壳体 2之间具 有一定的间隙空间 22， 该间隙空间 22可充满空气或其他气体； 所述容置部 1由可压缩性软 质材料制成， 例如， 硅胶、 橡胶或塑料； 所述加压装置用于增加间隙空间 22中的气体压力， 其可以通过向间隙空间中补充额外的气体而增加压力， 或者压縮间隙空间体积而增加压力， 亦或可以两者兼而有之；从而使容置部 2在气压的作用下被挤压而将其内部盛装的产品挤出。
产品组装时， 首先通过出口 12或按现有技术中的方法或结构将产品灌装到容置空间中， 再将容置部 1与壳体 2组装在配合在一起；使用时，使出口 12转至允许产品挤出的打开状态， 启动加压装置或对其施加作用力， 间隙空间 22中的气压增加； 从而对可压缩性软质材料制成 的容置部 1施加压力， 容置部 1被挤压， 其内盛装的物料或产品从出口 12被挤出； 待挤出所 需要量的产品后， 停止加压装置或撤去施加于作用力上的力， 间隙空间中的压力消除， 出料 停止。 当需要大量的产品时， 可以分次按上述操作分别挤出。
如图 6 10所示， 在某些实施例中， 所述加压装置为壳体， 所述壳体上设有单向气体阀， 并且其由具有弹性的适中可压缩性的硬性材料制成，例如硬性塑胶。壳体上共设有两个开口， 一个开口 21供容置部的出口配合并且配合后密封， 另一个开口处设有单向气体阀， 该单向气 体阀可以允许气体进入壳体内而不允许气体外泄； 组装完成后容置部是位于壳体内部的。 使 用时， 对壳体施加一个作用力， 壳体发生变形向内收缩， 同时由于其向外的气体通路都是闭 合的， 壳体与容置部间的间隙空间内的气体压力增大， 进而对容置部产生挤压力， 容置部内 的产品压力增大， 产品被从出口挤出； 待挤出所需量的产品时， 撤去外力， 产品停止挤出， 壳体在其自身弹力的作用下回复至原始状态， 此吋间隙空间内的气压为负压， 壳体上的单向 气体阀打开， 外界空气进入间隙空间中达到平衡状态， 至此单次挤出操作结束。 下次使用时 重复上述操作即可， 大量挤出时分次挤出时重复上述操作。
如图 1 5所示， 在另一些实施例中， 所述加压装置为可输出气体的气泵 3 , 气泵 3可通 过设置于壳体上的单向气体陶 23向壳体内的间隙空间 22中输送气体， 所述壳体采用非压缩 性刚性材料制成， 例如玻璃、 纤维玻璃。 壳体 2上共设有两个开口， 一个开口 21供容置部的 出口配合并且配合后密封， 另一个开口处设有单向气体阀 23， 该单向气体阀 23可以允许气 体进入壳体 2内而不允许气体外泄，气泵 3通过该单向气体阀 23向间隙空间 22中输送气体; 组装完成后容置部 1是位于壳体 2内部的。 使用时， 启动气泵 3或对其施加作用力， 气泵 3 将气体泵入间隙空间中， 由于壳体 2是采用非压缩性刚性材料制成的， 不可以变形， 故壳体 2内的间隙空间 22中的气压增大，进而使容置部 1中的产品被挤出；当挤出足够量的产品时， 气泵 3停止工作， 待间隙空间 22中的气压与外界气压平衡或接近平衡后， 产品挤出停止， 至 此， 单次挤出操作完成。
在某些较佳实施例中， 所述容置部 1的出口 12处设有单向阀 13， 所述单向阀 13使用允 许产品从容置部 1中挤出而不允许外界的气体进入容置部 1中。使用单向阔 13后可以避免在 挤出完成后装置回复至初始状态时可能会有空气进入容置部 1的问题， 从而可以避免产品与 空气接触质变或是有空气掺杂在后续产品中而影响挤出效果。
一种产品灌装和挤出方法， 该方法包括产品灌装和产品挤出的步骤；
所述产品包装的步骤包括：
S11产品灌装的步骤， 其包括将产品分装到容置部内的用于盛装产品的容置空间中， 所述容置部采用可压缩性软质材料制成， 容置部至少具有一个用于产品挤出的出口， 出口处 设有单向阔， 以允许产品从容置部中挤出而不允许外界的气体进入容置部中， 从而可以避免 外界空气进入容置空间中而使产品与空气接触质变或是有空气掺杂在后续产品中而影响挤出 效果；
S12 包装体组装的步骤， 将上述步骤灌装好的容置部置于壳体中， 壳体上设有与容 置部对应位置设有开口供容置部的出口穿出以使其内的产品可以被挤出， 壳体在与容置部配 合后开口处为密封结构； 容置部与壳体之间具有一定的间隙空间；
所述产品挤出的步骤包括：
S21 产品挤出的步骤， 通过加压装置施加压力使容置部与壳体之间的间隙空间中的 气压增加， 间隙空间中的气体进一步将压力传导至容置部表面， 使容置部内的产品被挤压而 经出口被挤出；
S22 状态恢复的步骤， 加压装置停止施加压力后， 产品挤出停止， 容置部的单向出 口关闭以避免空气进入容置部， 加压装置回复到初始状态以备下次使用。
下次挤出或需要多次挤出时， 重复上述 S21和 S22步骤。
如图 6 10所示，在某些优选实施例中，所述 S21步骤中施加压力是通过由具有适中弹性 的可压缩性的硬性材料制成的壳体完成的， 壳体上还设有允许气体进入壳体内而不允许气体 外泄的单向气体阀； 施加压力时挤压壳体， 壳体发生变形向内收缩， 使间隙空间中的气体压 力增大并对容置部产生挤压力； 撤去外力后， 容置部的单向出口关闭， 此时间隙空间内的气 压为负压， 壳体上的单向气体阀打开， 外界空气进入间隙空间中达到平衡状态而使外界气体 通过壳体上的单向气体阀进入间隙空间中， 壳体回复到初始状态， 至此单次挤出操作结束。 下次使用时重复上述操作即可， 大量挤出时分次挤出时重复上述操作。
如图 1-5所示， 在另一些优选实施例中， 所述 S21步骤中施加压力是通过可输出气体的 气泵完成的， 气泵可通过设置于壳体上的单向气体阀向壳体内的间隙空间中输送气体， 而壳 体采用非压缩性刚性材料制成， 例如玻璃、 纤维玻璃。 壳体上共设有两个开口， 一个开口供 容置部的出口配合并且配合后密封， 另一个开口处设有单向气体闽， 该单向气体阀可以允许 气体进入元壳体内而不允许气体外泄， 气泵通过该单向气体阀向间隙空间中输送气体。 启动 气泵或对其施加作用力， 气泵将气体泵入间隙空间中， 壳体内的间隙空间中的气压增大， 进 而使容置部中的产品被挤出； 当挤出足够量的产品时， 气泵停止工作， 待间隙空间中的气压 与外界气压平衡或接近平衡后， 产品挤出停止， 至此， 单次挤出操作完成。
该方法具体所使用的设备和设备的工作原理也可以参考上述的气压式挤出容器的相关描 述。
