Abstract
一种制备带条纹的牙膏的方法，其中看起来是没有条纹的第一种牙膏装在至少一部分侧壁是透明的容器中，在从容器中挤出时，就转变成带条纹的牙膏，这种方法包括，将第一种牙膏装在具有排出装置和在排出装置内具有形成条纹装置的容器中，依次将颜色与第一种牙膏不同的用以形成条纹的牙膏装入容器，形成条纹的牙膏，装在容器内与第一种牙膏分开的一个区域中，然后将第一种牙膏装入容器，当对牙膏施加压力时，使形成条纹的牙膏在装第二种牙膏的容器区域中施加到第一种牙膏上，并同时一起从容器中挤出，所以在挤出时，被挤出的牙膏看上去已经魔术般地转变成带条纹的牙膏。
Description
发明背景
1.
发明领域
本发明涉及带条纹的牙膏产品，更具体而言，涉及一种装在容器中的带条纹的牙膏或凝胶，该容器至少侧壁的一部分是透明的或半透明的，所以当消费者通过侧壁观察时，牙膏是没有条纹的，而在挤出牙膏时，牙膏的表面却是带条纹的，就好象是用魔术变成的，或好象是由具有不同颜色的第二种牙膏挤出的。
2.
现有技术
人们一直认为，在使许多产品被消费者认可方面，美化效果起着重要的作用。在许多情况下，人们在市场上一直利用装璜效果辩别具体的产品，识别具有具体特征的产品。在牙膏领域，在牙膏或凝胶中加入颜色明显不同的条纹是已知的。这种条纹能提供一种美化作用，使消费者感到愉快，并促进消费者，特别儿童使用这种牙膏。虽然这类产品已经得到消费者的认可，但却发现，将具有第一种颜色的牙膏封装在可压扁的容器中，在市场上是有希望的，该容器至少有一个透明的部分，透过它可以观察到装在容器中的牙膏产品，当从容器中挤出时，其中颜色不同的第二种牙膏形成的条纹效果将会魔术似地出现在所装牙膏的表面上。
发明概述
按照本发明，提供一种优美的令人愉快的有条纹的牙膏。在从容器中挤出第一种没有条纹的牙膏时，却出现了条纹，在加压下，第一种无条纹的牙膏和颜色与其不同的第二种牙膏接触，第二种牙膏与第一种牙膏在容器中分开保存，该容器侧壁的至少一部分是透明的，使用者透过透明的部分，可以观察到没有条纹的第一种牙膏，当在加压下开启时，第二种牙膏就作为表面条纹附着在第一种牙膏上，这二种牙膏同时从容器中挤出。正如使用者所看到的，挤出时，利用第二种牙膏魔术似地产生清晰的条纹效果，条纹的颜色与第一种牙膏不同。
对消费者而言，在本发明所用的容器施加压力之前，看起来就和装无条纹的牙膏容器一样。在对容器中的牙膏施加压力时，出乎预料地从容器中挤出一条带条纹的牙膏，就好象是用魔术变出来的，以一种非常吸引人的方式向消费者提供一条带条纹的牙膏。牙膏不可思议地从不带条纹转变成带条纹的，这是使产品特别具有吸引力的一种方法，从而促进消费者，特别是儿童使用这种产品。
对优选实施方案的说明
本文所用的术语“透明的”，系指具有可见的特性，其含义包括目视是透明的物体也还包括半透明的物体。
术语“不同颜色”，其含义包括与第一种颜色不同的颜色，在色调上比第一种颜色或明或暗或不同或形成反差。
本发明的透明容器所装的第一和第二种牙膏组合物，基本上是相同的组合物，但这二种牙膏包含不同的着色剂磨料，和不同的增稠剂含量。在本发明的范围内，第一种牙膏可不包含任何着色剂，可以是半透明的，或通常是透明的。制备该各个牙膏组分所用的着色剂，当按推荐量使用时，在药物学和生理学上是无毒的。这些着色剂包括颜料和染料。在本发明的实践中所用的颜料，包括无毒的、不溶于水的无机颜料如二氧化钛和绿色的三氧化二铬、蓝色的佛青和粉红色的氧化铁以及以提供FD&C染料的钙盐或铝盐利用氧化铝制备的不溶于水的染料色淀，例如FD&C绿1#色淀、FD&C蓝2#色淀、FD&C R&D 30#色淀、和FD&C黄15#色淀。颜料的粒度为5-1000μm，优选250-500μm。包含颜料的牙膏在本文中称作“膏剂”。
在本发明的实践中使用的染料，均匀地分布在整个牙膏中，它们是目前按适用于食品和摄入药物的食品药物及化妆品条例(FoodDrug & Cosmetic Act)，检验合格的符合要求的食品色素添加剂，其中包括染料如FD&C红3号(四碘荧光素钠盐)、食品红17(6-羟基-5-{(2-甲氧基-5-甲基-4-磺苯基)偶氮}-2-萘撑磺酸二钠盐)、食品黄13(喹啉邻苯二酮的一和二磺酸混合物的钠盐或2-(2-喹啉基)茚满二酮)、FD&C黄5号(4-对-磺苯基偶氮-1-对-磺苯基-5-羟基吡唑-3羧酸钠盐)、FD&C黄6号(对-磺苯基偶氮-β-萘酚-6-一磺酸钠盐)、FD&C绿3号(4-{[4-(N-乙基-对-磺苄氨基)-苯基]-(4-羟基-2-锍苯基)-甲撑}-[1-(N-乙基-N-对-磺苄基)-AE-3，5-环己二烯亚胺的二钠盐])、FD&C蓝1号(二苄基二乙基-二氨基三苯基甲醇三磺酸二钠盐硬石膏)、FD&C蓝2号(靛蓝的二磺酸钠盐)、以及它们按不同比例的混合物。在本发明中，在牙膏中效果最好的染料浓度为总组合物重量的约0.05％(重量)至约10％(重量)，优选约0.1％(重量)至约5％(重量)。包含染料着色剂的牙膏在本文中被称作“凝胶”。
在本发明的实践中，优选在透明容器中封装的第一种或主体牙膏中包括的着色剂是一种色淀染料或颜料，并优选在第二种形成条纹的牙膏中包括的着色剂，是食品着色的染料。
在按照本发明制备第一和第二种牙膏组分的过程中，使用一种可口用的载色体，其中包括具有润湿剂的水相，润湿剂优选甘油和山梨糖醇，或烷撑二醇如聚乙二醇或丙二醇，其中存在的水量一般为牙膏总重量的约5％(重量)至约25％(重量)，甘油、山梨糖醇和/或烷撑二醇成分一般为牙膏总重的约20％(重量)至约60％(重量)，更一般为约25％(重量)至约50％(重量)。

通过使用者对组分施加压力，可将本发明的二种牙膏组分，以所控制的量从容器中同时挤出，例如从被挤压的容器，可抽吸或可压扁的管中挤出。对本领域而言，适合这种挤出的容器是已知的，例如在美国专利4,687,663和4,487,663中所公开的，在此引入这些公开内容作为参考。
附图
●图1是本发明一个实施方案的正视图，其中示出具有透明侧壁的可压扁的管，用来以带条纹的形式同时挤出其中所装的双牙膏组分。
●图2是可压扁管的局部中央断面图，其中包含二种牙膏组分，并能以带条纹的形式同时挤出。
●图3是可压扁管的局部断面图，将其中的二部分牙膏一起挤出，形成一种吸引人的带条纹的产品。
参看附图1-3所示的本发明的实施方案，具有透明侧壁10a的可压扁的牙膏管10，装有带螺纹的头部顶端11，其上有多条螺纹12，用于固定管10头部顶端上的盖13，管10具有向顶端倾斜的斜面14，排出通道或排出口15。
管10是由塑料材料制成的，例如高密度的聚乙烯或聚丙烯，具有足够薄的侧壁，能被反复地弯曲，以施加压力挤出装在管中的牙膏组分。
位于向管10顶端倾斜的斜面14内是在头部顶端下面的一个区域，它从带螺纹的头部顶端11向后伸入管10，以界定第一区域16，第一区域16被向顶端倾斜的斜面14的不透明的套管18隐蔽而看不见。
被向顶端倾斜的斜面14包围的、并被管10不透明的套管18隐蔽看不见的第一区域16，装满具有第一种颜色的形成条纹的凝胶19。管10剩下的部分，装满具有差别颜色的膏剂20，在向管10的侧壁10a施加压力时，形成待成条纹的牙膏体，凝胶19和膏剂20在区域16沿表面22互相接触。
为了使在区域16内所装的形成条纹的凝胶19，能在膏剂20挤出的条状体上形成条纹，在位于头部顶端11排出通道15内的插入管25中，有至少一个，优选多个形成条纹的通道24，插入管25通到排出通道15和管10装膏剂20的第二区26之间。为了产生特定宽度的带色条纹，条纹出口24的宽度必须不宽于所产生的条纹。在膏剂20离开管口15时，条纹可能略微展开，展开的程度，取决于以下因素，例如膏剂的粘度、和挤出的压力。然而，为了使条纹具有良好的再现性和良好的清晰度，只略微展开是允许的。因此，条纹出口24的宽度，必须与产生的条纹23的宽度相同，或略小。
在操作过程中，将管10装满能以带条纹的牙膏条29的形状挤出的牙膏组分物，为此首先将能形成条纹的牙膏凝胶19装入管10中。将这种材料装入第一区域16，装入容器的量不超过插管24的入口27，并在位置22以上，位置22是管10内二种不同颜色的牙膏材料接触的位置。然后将膏剂材料装入管10，充满管的其余空间，使用者透过透明的侧壁10a能看见至少一部分膏剂，这种膏剂材料，形成被挤出的带条纹的牙膏条29的本体20。形成条纹的凝胶19与本体牙膏膏剂20的体积比例，一般为1∶6-1∶15，优选1∶9。
在向管10的侧壁10a施加压力，挤出带条纹的牙膏条29时，形成带条纹的牙膏29本体的膏剂20，是通过插入管25的入口27挤出的，经排出通道28引导至管10的排出口15。与此同时，对管侧壁10a施加的压力，也使膏剂材料20发生移动，膏剂20沿轴向向封装在管10区域16内的形成条纹的凝胶19的方向移动。由于这种压力，强制形成条纹的凝胶19通过形成条纹的出口24，到达正在通过插入管25的排出通道28的膏剂材料20的条上。以这种方法，使形成条纹的凝胶19成为膏剂条29的一部分，这二种牙膏以带条纹的牙膏条29的形式从管10的排出口15排出，在透过管10透明的侧壁10a观察无条纹的膏剂挤出时，带条纹的牙膏条29就魔术似地形成了。
根据优选的实施方案以所附的实例说明了本发明。在本说明书和所附的权利要求中提到的所有部分和百分数都是以重量表示的。

在凝胶和膏剂组合物的制备过程中，制备甘油、山梨糖醇、聚乙二醇600和水的载色体溶液，对其施加28-30磅的真空，向其中加入糖精、氟化钠和羟甲基纤维素的混合物。然后将染料或TiO2与载色体混合。在施加的28-30磅真空下使混合物脱气5分钟。然后，在初步脱气后，加入toxosil 103、Zeodent 165和月桂基硫酸酯钠盐。混合这些成分。混合约5分钟后，施加真空，认为牙膏制剂已经制成，将凝胶和膏剂组分封装在附图1-2中所示类型的管中，其体积比例为1∶9。在管10中只膏剂是可看见的，凝胶组合物被固定在管顶端的不透明套管14隐蔽起来，看不见。
在封装之后，挤压管中的牙膏产品，挤出与众不同的带条纹的条状产品，在白色牙膏产品的表面上，沿长度方向伸展着连续的兰色条纹，这些条纹看上去是自发产生的，就好象用魔术在正挤出的白色牙膏上变出来的。
