Description

密封饮料的饮料容器及其孔塞 技术领域 本发明涉及密封饮料的饮料容器, 尤其涉及备有两个以上 (含两个) 孔洞的密封饮料的饮料容器及其孔塞。 背景技术 目前,密封在饮料容器中的饮料制品 /液态食物制品,无论是需要冰柜 雪藏保鲜类, 或者是允许室温和灯光下存放的抗菌保鲜类, 或者是铝罐, 铁罐, 玻璃瓶装, 塑胶瓶密封保存类, 当需要倾倒出饮料饮用时, 有以下 几种方式 /方法:
A. 目前很多的饮料容器都使用了一种多层复合纸, 该纸是用纸, 铝 箔, 和多层塑料薄膜夹层而成。铝箔可以遮挡光线, 防止氧化; 纸则具有 一定的强硬度; 多层塑料薄膜进行粘合, 印刷和最内层的饮食级别的保护 膜, 经过夹层制成的包装材料, 下文简称为"复合纸", 或者"抗菌纸"。 在 加工抗菌纸的过程中, 先在定位为位于将要制成的纸盒顶部纸层上,冲出 一个略大于吸管直径的圆孔,冲好后再与其它材料复合夹层成为包装复合 纸。 因此, 消费者只需用吸管通破复合包装材料的铝箔和塑料薄膜, 就可 破坏密封, 插入饮料吸管。 由于铝箔遮挡光线和阻挡氧气, 只要包装盒和 被包装的饮料进行了杀菌处理,密封包装的饮料可以无需雪藏和常温下保 鲜 6个月以上。 用这种材料制作的立方体包装盒, 最典型的是 UHT或者 HTST杀菌处理的包装饮料。但是,如果要将纸盒中的饮料倒入杯中饮用, 就要用剪刀斜着剪去包装的一角, 打开一个倾倒的开口。 但是一旦剪开, 纸盒就不可能再密封了, 因此这种方式只适合于吸管饮用, 或者就是一次 全部倒出饮用, 显然适合于较小的包装盒。 此外, 找到剪刀并不容易和相 当麻烦。 B.在饮料容器上装有圆形瓶口和瓶盖, 旋转拧开瓶盖后, 或者需要 再撕开瓶口上粘贴的密封膜后。可以多次地倾倒出容器中的饮料。这种方 式, 对鲜奶、 豆桨、 果汁类饮料的较大容量的包装, 常见的有: 纸盒顶部 加装了旋拧式塑料盖口的饮料包装。这类包装,反复多次地开盖和倒出十 分容易。但是,这种包装,由于附加的塑料瓶口材料和包装盒的材料不同, 例如纸盒加塑料瓶口瓶盖,密闭性和长期密闭可靠性很难, 因此, 比较适 合于冰柜保鲜的包装方式。例如, 巴氏牛奶。但是, 如果做成室温和灯光 下存放的抗菌保鲜类包装, 增加瓶口瓶盖, 会令包装成本相对的增高。
C.在使用抗菌纸的立方包装中, 当制作大容量的饮料盒时, 一个包 装盒可以倒出多杯饮料, 或者个人分成多次饮用时, 用上文 "A"的方法, 剪开包装倾倒, 就不方便重,新密封而无法让容器内未倒出饮料能够保洁。 为此, 有一种发明, 是在抗茵纸的立方容器的顶面的一角, 有一个 "倾倒 口装置"。 食用盒中的饮料时, 首先把倾倒口装置上的"塑料外盖"掀开, 而后:有的设计是把密封倾倒口的保鲜膜撕掉,有的设计则是把一块塑料 块压下压破其下面的无菌纸的预留孔位, 打开一个饮料倾倒口。 总之,饮 料倾倒口打开后, 就可以在装置的"杯嘴"帮助 (导向) 下, 倾倒出容器中 的饮料。暂时不倒时, 该装置的塑料外盖可以扣回, 盖上容器的开口。 此 装置的最大问题在于保洁方面:
( 1 ) 用手指撕开密封倾倒口的保鲜膜 (且不谈此保鲜纸的密封可靠 性), 或者在另一种设计中用手指压下塑料块压破其下面的无菌纸的预留 孔位, 一旦手指 (例如餐厅服务生的) 不干净, 带菌, 都令此设计在清洁 卫生上留下缺点。
(2) 另一个更大的不卫生的隐患, 是在这种包装的运输和储存过程 中, 一旦让污水 (动物、 噙鸟或者昆虫的体液、 分泌液)、 污尘、 不安全 的物质 (包括犯罪行为), 流入或者落入上述"倾倒口装置"上, 残存在该 装置和无茵保险层的间隙和该装置的复杂造型的边边角角中,在使用此开 口装置倾倒容器中的饮料时, 会冲带出污物。显然不安全, 不卫生, 会损 害甚至危害喝饮料者的健康。 D.在使用无菌纸的包装中, 还有一种顶部有一个可以用手撕开的标 签密封的盒式包装, 撕开一个"桃形"的开口, 可以对嘴喝, 或者用吸管插 入。为了饮料的卫生,该铝膜密封标签并非是用胶水, 用自干胶粘贴来密 封的, 而是在上述抗菌纸的抗菌原理下, 直接复合(夹层粘合)在包装最 内层的 "可包装食品类"塑胶薄膜上的, 一旦撕下, 就不可再"粘"回去, 再 恢复复盖。 因此, 此设计被用于小包装的饮料上。
E. X于铝罐包装的饮料, 通常使用了拉环幵盖的装置。 由于罐顶和 罐体必须分开制作, 而后在饮料灌入后, 封压密封。 因此, 灌顶圆盘和圆 柱罐体之间有一个环形的压装加工沟槽和环形的接缝; 同时,还有灌顶圆 盘上的拉环幵罐装置与灌顶平面间的空隙。这些灌顶的沟槽、接缝和空隙, 都是藏污纳垢的地方, 当消费者, 用拉环打开饮料洞后, 对嘴喝饮料时, 实在是非常不卫生的, 即使到入杯中,饮料流经顶面的压装沟槽和环形的 接缝, 同样是十分不卫生的, 是一种适合吸管,而不适合于直接对嘴或则 倾倒出来饮用。
F. 上述 "E"所述的带有拉环开口装置的铝质圆盘, 还被压装到塑料圆 柱体的广口瓶上,成为另一类的饮料包装容器。 由于其拉环开口设计和上 述" D"所述的带有拉环开口装置的铝罐一样,其不卫生的问题 I缺点同样 不可避免。
上述" E"所述的带有拉环开口装置的铝质圆盘, 还被设计成使用薄铁 制成, 并且压装薄铁冲拉出的容器上 (例如, 食物罐头), 成为另一类的 饮料包装容器。 由于其拉环开口设计和上述" D"所述的带有拉环开口装置 的一样, 只是材质改变, 其不卫生的问题 /缺点同样不可避免。
解决上述的目前饮料包装所存的问题,设计出一种更加卫生和方便多 次倾倒饮料的新的饮料包装方式, 是非常必要的。 发明内容 本发明是为克服上述问题和缺点而研发的,其目的在于提出一种更加 卫生, 更加安全, 又十分方便的密封饮料的饮料容器及其孔塞。 为此本发明提出的技术方案是:在全部使用抗菌包装纸制作的饮料容 器上面, 或者部分使用抗菌包装纸制作的饮料容器的抗菌包装纸上面,预 制了两个以上(含两个) 由消费者通开(打开) 的密封孔洞。所谓"预制", 既是在加工抗菌纸的过程中,先在位于将要制成的包装顶部的纸层上,按 设计的数目 (两个以上, 含两个)、 形状、 尺寸和位置, 冲出孔洞 (当孔 洞较小时, 孔洞的闭合曲线包围的部分冲掉), 或者冲出断口 (当孔洞较 大时, 孔洞的闭合曲线包围部分冲出裂缝, 纸被切破, 但是有牵连, 未完 全冲掉, 或者只有少部分被冲掉)) 而后再与其它材料 (铝箔, 塑胶薄膜) 复合夹层制成为复合包装用纸,又称抗菌纸。从而, 制备的孔洞处的强度 会很低, 只有铝箔和塑料膜在密封孔洞, 很容易被下文设计的孔塞通破, 而且捅出所需要的形状和尺寸。 本发明中,预制的两个以上(含两个) 的密封孔洞的形状可以是圆形 或者非圆形, 尺寸可以大小相同或者不同。然而, 按照密封孔洞的用途不 同而分为 3类:
(1)通气孔:用于让倾倒饮料时容器内饮料与大气相通的一个孔洞。
(2)饮料倒出孔:用于倾斜容器倒出饮料的饮料孔洞。
(3) "备用的饮料倒出孔"下文简称"备用孔": 第三类,或者更多的密 封孔洞, 都是为了增加饮料倒出速度而设的。 消费者可以打开"备用孔", 也可以不用。 显然, 打开的 "备用孔"越多, 则倾倒饮科的速度就越快。 本发明中, 上述的饮料倒出孔和通气孔尽量, 尽可能地分开和远离。 而"备用的饮料倒出孔"则要尽可能的接近饮料倒出孔。 本发明中,在饮料灌装和密封后,在上述饮料容器上面的抗茵复合包 装纸上预制的两个以上的密封的孔洞的上面, 贴上一件或者多件"保洁标 签", 该标签有以下特征:
(1) 尺寸大于密封孔洞。
(2) 周边有自干胶的塑料薄膜, 或者是周边有粘胶的铝泊塑料复合 薄膜, 或者是无胶的塑料贴膜或者是透明塑料胶纸。 (3) 上述标签可以印上图、 字, 甚至兼做质量检查或者封装标签。 这些标签的主要用途,是保护预制的孔洞极其四周的清洁干净, 以及 保证在生产后的运输和库存中,容器在塞孔部位及洞口周围的清洁和不被 污染。但消费者需要打开密封孔时,要首先部分或者全部掀起这些保洁标 签, 暴露密封孔, 而后才能使用孔塞开孔。
这些标签的另一个用途,是在上述通气孔或者饮料倒出孔等,在孔洞 打开后, 一旦不倾倒饮料时, 也可以用"保洁标签"覆盖, 只要此后保持垂 直地放置,就可以通过覆盖孔洞,令容器内未饮尽的饮料保持清洁。但是, 由于此标签并不遮光和阻挡氧气入侵等, 容器内的饮料不可长久室温保 鲜。
本发明提出的另一技术方案是:饮料容器可以附带一种称为 "孔塞 "的 装置,该孔塞用以打开上述密封饮料的饮料容器上预制的孔洞。另该孔塞 与该饮料容器的两个开孔的尺寸紧密配合, 孔塞可以反复使用。
该孔塞本身带有斜口或刃口, 是打开密封容器的密封孔洞的专用工 具,可以打开使用抗菌复合包装纸制作的饮料容器上面, 或者部分使用抗 菌复合包装纸制作的密封饮料容器上面所预制的所有的密封口。我们可以 使用极其简单, 方便的方式就可打开上述饮料包装所预制的饮料倒出孔, 通气孔, 和"备用的饮料倒出孔"。 该孔塞也可以用来堵塞上述密封饮料 的饮料容器。
上述的孔塞,可以是带有通孔的孔塞,而且孔塞可以插入密封饮料的 饮料容器的倾倒饮料的孔洞中,且紧密配合;在倾倒容器内的饮料时, 孔 塞的管嘴可以帮助饮料倒出时的导向。也可以是带有螺紋的孔塞,可以是 或者圆锥形螺纹, 或者带有斜面的拧紧牙扣,把孔塞越旋越紧地旋入在饮 料容器的倾倒饮料的孔洞中。 或者选择带有中心通孔的孔塞例如管形孔 塞, 而且可以把孔塞旋紧在饮料容器的倾倒饮料的孔洞中, 且紧密配合; 在倾倒容器内的饮料时, 孔塞的中心通孔的管嘴可以帮助饮料倒出的导 向。
上述孔塞可以是一件,其两端可以分别塞紧饮料容器顶部打开的两个 密封孔洞。上述孔塞也可以是两件以上(含两件) 的组合, 其所含的部分 可以分别塞紧饮料容器顶部打开的两个密封孔洞。
本发明中,所附带的孔塞,无论是一件式的,还是两件以上组合式的, 都最少有一件可以插入和通开上述饮料包装所预制的饮料倒出孔,而且该 饮料包装的所附带的孔塞, 可以插入孔洞中 (孔塞设计成插入式时), 或 者可以拧入孔洞中 (孔塞设计成旋入式时), 均与被打开的密封孔紧密配 合和固定。如果孔塞中心有倒出饮料的通孔, 则该插入, 或者依设计不同 而拧入的孔塞, 可以成为类似"壶嘴"一样帮助容器中饮料的倒出导向。
上述饮料包装容器打开倾倒饮料后,为了保洁,一旦不再倾倒饮料时, 可以用孔塞堵塞封闭已经打开的孔洞, 或者将孔塞的中心孔道重新盖上。 本发明中, 备有倾倒饮料开孔的饮料容器及其开孔的孔塞的设计操作简 便, 而且更加卫生, 更加安全。
下面结合附图, 对发明的具体实施作进一步的详细说明。 对于所属技 术领域的技术人员而言,从对本发明的详细说明中, 本发明的上述和其他 目的、 特征和优点将显而易见。 附图说明 图 1A— 图 1F是圆形和圆形连通孔洞的饮料倒出孔的设计示意图。 图 2A - 图 2D是设置有两个孔洞的密封饮料的饮料容器及其孔塞的 第一实施例示意图。

本发明中,饮料容器的饮料倒出孔的圆形和圆形连通孔洞的一较佳实 施方式如下:
圆型的饮料倒出孔强度好, 开孔模具简单, 孔塞可以任意方向插入, 而且可配合螺旋孔塞的旋入。为此首先讨论圆形的饮料倒出孔的设计,包 括了"备用孔 "的设计。
图 1A— 图 1F是圆形和圆形连通孔洞的饮料倒出孔的设计示意图。 其中的 1代表饮料倒出孔, 11, 12代表"备用的饮料倒出孔"。 孔洞的直 径画成相同的 D1 , 是为了方便用同一个孔塞, 就可以打开所有的饮料倒 出孔。 具体的说:

图 1A— 图 1F显示的为配合圆柱形孔塞使用的几种饮料倒出孔的密 封孔洞的设计, 该设计简单易行, 容易实现。
本发明中所配合饮料容器使用的两件一组的孔塞较佳实施方式如下: 图 2A― 图 2D是设置有两个孔洞的密封饮料的饮料容器及其孔塞的 第一较佳实施例示意图。 其中所配用的两件孔塞组合均为圆柱管塞。
具体描述为图 2A是保洁袋 9中的两件对接的圆柱管塞 21和 22; 图 2B是两件孔塞对接并插入 (盖住) 饮料倒出孔 1和通气孔 3 ; 图 2C是 分开对接的两件孔塞, 即可以倾倒容器 5中的饮料 6; 图 2D是只插入圆 柱管塞 21,倾到时空气 8进入通气孔 3,饮料从饮料倒出孔 1,经过圆柱 管塞 21的管洞口 7倾倒出。 上述的孔塞由饮料倾倒的圆柱管塞 21和透气用的圆柱管塞 22组成。 两件圆柱管塞可以插接组装成一件 "C"型附件, 而后封装在保洁的小塑 胶袋 9, 出厂时, 图 2A将会作为附件粘附在饮料容器的外壁上。 消费者饮用饮料时, 取出上述图 2A的" C"型附件, 用其的尖端对应 地插入饮料容器包装 5顶上准备好的密封孔 1和 3中。倾倒饮料时, 圆柱 管塞的使用如图 2C所示, 圆柱管塞 21和 22分成两件, 分别插在饮料容 器的两个孔 1和 3中, 而后倾倒容器, 饮料会从圆柱管塞 21的 7孔洞中 倒出, 同时, 空气 8从圆柱管塞的孔中进入。 当暂时不饮食容器中的饮料 时, 两件圆柱管塞对接 (22插入 21 中)在一起后, 两端分别垂直插入饮料 容器的两个密封孔 1和 3中。这样, 圆柱管塞就重新完全地密闭了饮料容 器的开口。
有必要一提的是,该两件圆柱管塞,每一件都可用目前的饮料吸管相 同原理的生产设备生产, 当然, 直径要加大很多。
在倾倒饮料时, 透气用的圆柱管塞 22可以不用插入图 2C的孔 3中, 也可以完成饮料的倾倒(见图 2D所示)。在倾倒饮料时,透气用的圆柱管 塞 22可以反过来将长的一段插入饮料容器中, 这样反过来插入透气用的 圆柱管塞 22的好处是显见的: 可以令透气用的圆柱管塞露在容器外的部 分相对短一些, 从而便于掌握倾斜倒出饮料。
图 3A、 图 3B和图 3C是设置有两个孔洞的密封饮料的饮料容器及其 孔塞的第二较佳实施例示意图。其中所配用的两件组合: 旋入式带"壶嘴" 的孔塞和圆柱管塞。
其中图 3A是由旋紧在饮料倒出孔 1的旋入式带"壶嘴"的孔塞 31 ,和 塞入通气孔 3的圆柱管塞,两件一组的孔塞封在附件塑胶保洁袋 9中。 311 是旋入式带"壶嘴"的孔塞打开饮料倒出孔的双刃"刀口", 312是螺紋, 313 是把旋入式带 "壶嘴 "的孔塞在饮料倒出孔扭紧的"蝴蝶翼"。 图 3B是两件 孔塞对接并插入 (盖住) 饮料倒出孔 1和通气孔 3 ; 而图 3C是分开对 接的两件孔塞, 即可以倾倒容器 5中的饮料 6 ; 空气 8从孔进入, 饮料从 管洞口 7倾倒而出。 该较佳实施例的特点是带"茶壶嘴 "式的饮料倒出嘴的孔塞,是一件铸 塑的构件, 而且, 是通过罗口旋入饮料倒出孔 1, 旋入的部分有打开预留 密封洞的双刃刀口 311, 而罗旋口的螺纹 312很短, 塑胶孔塞只需旋转约 45至 180度就可以旋紧,实际上是"扣紧"。为帮助旋入式带"壶嘴"的孔塞 31 , 在此孔塞上设计了"蝴蝶翼" 313, 帮助锁紧旋入式带"壶嘴"的孔塞。 蝴蝶翼 313的方向和弯曲的塞嘴在一个平面上以便尽量减少包装后的两件 式组合孔塞包在保洁塑胶袋 9中后, 厚度尽可能的少些 (图 3A中的 P-P 透视方向的厚度)。
旋入式带"壶嘴"的孔塞中心的通孔,是倒出饮料的 "茶壶嘴",当图 3C 的饮料容器向左倾斜时, 空气 8从孔进入, 同时饮料从图 3C的管洞口 7 中倒出。 与图 2A— 图 2D的原理一样, 倾倒饮料时, 图 2A - 图 2D的 透气用的圆柱管塞 22,可以不插。也可以反过来将长的一端插入饮料容器 的通气孔 3中。 当暂时停止倾倒饮料时,可以把带饮料倒出嘴的孔塞向内旋转,而后, 将圆柱管塞 22 的一端插入饮料倒出嘴的"壶嘴"中, 而另一段插入饮料容 器的通气孔 3中 (见图 3B) , 这样, 就把饮料容器重新密封起来达到保洁 的目的。 图 4A、 图 4B和图 4C是设置有两个孔洞的密封饮料的饮料容器及其 孔塞的第三较佳实施例示意图。其中所配用的两件组合:带撮箕倒出嘴 411 的塑胶孔塞 41和圆柱管塞 22
其中图 4A是由旋紧在饮料倒出孔 1的带撮箕式饮料倒出嘴 411的塑 胶孔塞 41, 和塞入通气孔 3的圆柱管塞 22, 分别封在同一个塑胶保洁袋 9中。 图 4B是带撮箕倒出嘴的塑胶孔塞 41旋入饮料倒出孔 1, U形的圆 柱管塞 22的一头插入(盖住)带撮箕倒出嘴的塑胶孔塞 41的通孔和通气 孔 3。 如图 4C所示, 倾倒饮料时, 饮料从 7倒出, 空气 8从通气孔 3进 入。 该较佳实施例的特点是饮料倒出孔塞,是一件铸塑的带撮箕倒出嘴的 塑胶孔塞 41 ,此带撮箕倒出嘴的塑胶孔塞嘴,是通过罗口旋入饮料倾倒孔 的 1, 旋入的部分有打开预留密封洞的刃口, 而旋入的螺紋很短, 带撮箕 倒出嘴的塑胶孔塞嘴只需旋转约 45至 180度就可以旋紧, 实际上是"扣 紧"。 此两件一组的另一件, 是一件 "U"的圆柱管塞 22, 该圆柱管塞 22的 外径与带撮箕倒出嘴的塑胶孔塞嘴的内孔紧密配合。 此两件一组的孔塞, 一起包在塑胶保洁袋 9中。 带撮箕倒出嘴的塑胶孔塞嘴的通孔, 是饮料的倒出口, 当图 4C的饮 料容器向左倾斜时, 空气 8从图 4C的通气孔 3进入, 同时饮料从图 4C 的管洞口 7中倒出。 与上述第一第二较佳实施例的原理一样,倾倒饮料时, 圆柱管塞 22, 可以不插, 如图 4C所示。
当暂时停止倾倒饮料时,可以把 "U"形的圆柱管塞 22的左端插入带撮 箕倒出嘴的塑胶孔塞嘴中, 同时, 又可以把圆柱管塞 22的右端插入通气 孔 3中, 如图 4B所示。 这样, 圆柱管塞 22 同时塞上饮料倒出孔和通气 孔, 保护了容器中饮料 6的清洁。 本发明中所配用的一件式的双孔塞的实施方式如下:
5A、 图 5B和图 5C是设置有两个孔洞的密封饮料的饮料容器及其 孔塞的第四较佳实施例示意图。该较佳实施例显示了一件式的弯管式双孔 塞。
其中图 5A是保洁袋 9中的一件式的弯管式双孔塞 51, 该双孔塞 51 是最简单的两端折弯管式双孔塞。图 5B是弯管式双孔塞 51插入饮料倒出 孔 1和通气孔 3。 图 5C是取掉弯管式双孔塞 51后, 从饮料倒出孔 1倾 倒出容器 5中的饮料 6。 倒出了饮料 62, 同时空气 8进入通气孔 3。
图 6A― 图 6D是设置有两个孔洞的密封饮料的饮料容器及其孔塞的 第五较佳实施例示意图。 该较佳实施例显示了一件式的铸塑式双孔塞。
其中图 6A是包在塑胶保洁袋 9中一件式的铸塑式双孔塞。 其中 661 是打开饮料倒出孔的铸塑式双孔塞 "刀口"。图 6B的 111和 112是贴在密 封容器 5的饮料倒出孔 1和通气孔 3上面的保洁标签。图 6C中铸塑式双 孔塞 61插入饮料倒出孔 1和通气孔 3中。 注意, 此时在图 6B中所显示 的保洁标签 111和 112已经在开口前撕掉。 图 6D, 取去双孔塞, 可以从 饮料倒出孔 1倾倒出容器 5中的倒出了饮料 6,同时空气 8进入通气孔 3。
图 5, 图 6, 都是一件式的塑胶双孔塞的设计。 其特点是一件式的双 孔塞的两端可以同时密封饮料倒出孔和通气孔。
图 5A中显示了一件式的弯管式双孔塞的设计。
图 6A中显示了一件式的铸塑式双孔塞的设计。 比较上述两种双孔孔塞, 各有优缺点:
a. 图 5A中的弯管式双孔塞 51,用饮料吸管生产设备就可以生产,而 且作为附件, 体积小, 重量轻。而且, 对倾倒饮料孔所需的面积较少的小 容积包装来说, 此类管形双孔塞的设计比较合理和实用。 当然, 弯管式双 孔塞 51也可以做成其饮料倒出孔塞的一端较粗,这在技术上也并不困难。
b. 图 6A中的铸塑式双孔塞 61,用塑料注射机和模具生产,特点是造 形设计可以多种多样,特别是可以改变两个密封孔洞的大小和形状:倒出 饮料的饮料孔可以比通气孔大很多,这对于饮料是黏度较大的液态食物产 品来说是很重要的。 此外, 倒出饮料的饮料孔, 可以是非圆形的, 见后文 和图 7显示了几种双孔的形状设计。 c 当倒出饮料的饮料孔是多个孔洞时, 例如 2个 (图 1B) , 3个 (图 1C 和 ID)或者更多个时, 图 6A中的铸塑式双孔塞 61, 其左端的孔塞可以设计 成同时插入并堵塞全部饮料倒出孔的多头式孔塞。为便于开孔,所有的密 封孔都相同尺寸, 即全部都可以用孔塞 61右端的孔塞通开。 单一件式双孔塞的缺点是这种孔塞通常是插入式的:插入容器的双孔 中, 而不是旋转拧入容器的双孔中。但是, Xt复合夹层纸包装而言, 可以 将"倒饮料孔"的一端, 设计成旋转拧入, 而后利用纸包装的软变形特点, 把双孔塞的另一端插入通气孔中。 当然,这样做的问题是, 倒饮料的孔必 须是圆孔, 才能旋转拧入。显然, 不可以是椭圆形, 三角形, 非圆形的其 它异形孔。
本发明中, 釆用不同形状双孔的较佳实施方式。 图 7A— 图 7F显示 了不同形状的饮料倒出孔和通气孔的设计示意图。
为配合双孔塞的的实施, 图 7A— 图 7F以顶部是矩形为例, 给出了 几种密封饮料容器的饮料倒出孔和通气孔的不同形状。当顶部为圆形, 或 者正方形, 或者"屋顶形", 或者其它形状时, 设计类似。 图 7A - 图 7F 是矩形的纸盒容器顶部的 6种不同开孔的俯视图。视图的左上角是饮料倒 出孔, 右边是通气孔。
除了图 7A为双圆形孔外, 其余的设计中的倾倒饮料的饮料倒出孔均 为非圆形的开口。 图 7A— 图 7F中的所有的饮料倒出孔, 都比通气孔大 很多, 这样令饮料倒出容易很多, 特别是对于黏度较大的液态食物产品。 图 7A— 图 7F中的所有设计,两个孔尽可能的远离。最远的设计在图 7F 中。其中图 7B, 7D, 7F的长形的, 扁的饮料倒出孔, 都可以令作为附件 的铸塑的双孔塞的厚度比较薄一些,从而让孔塞附件更适合于贴在包装盒 的侧壁上。 当然, 将孔塞设计成扁形, 或者把无法改扁的部分设计成可以 装卸的零件, 都是令孔塞附件较扁平的方法。 虽然"透气孔 "也可以有各种孔形, 但是图中的透气孔都设计成圆形, 这是因为加工圆形的模具制造成本低, 模具的使用寿命也较长。 本发明中,备有倾倒饮料开孔的饮料容器及其开孔的孔塞的设计搡作 简便, 而且更加卫生, 更加安全。
当然, 本发明还可有其他实施例, 在不背离本发明精神及其实质的情 况下,所属技术领域的技术人员当可根据本发明作出各种相应的更改和变 形, 但这些相应的更改和变形都应属于本发明的权利要求的保护范围。
