Abstract

一种剃须装置,它包括:至少一个刀片和一个剃 须复合物,所述复合物有一个与刀片的刃口邻近接触 使用者皮肤的表面。所述复合物包括:不溶于水的基 体材料、有效数量的助剃材料以及有效数量的非水溶 性香精油材料,在剃须期间,被水溶出的助剃材料从 复合物释放出来,与此同时,所述不溶于水的香精油 材料也从中释放出来,从而在每平方厘米皮肤表面上 敷加至少1毫微克左右的香精油。

Description

本发明涉及剃须装置,尤其是湿法剃须的剃须装置。
在湿法剃须的剃须装置中,诸如剃刀在皮肤上的摩擦拖动、割断毛发所需的力量以及对先前皮肤的损伤引起疼痛等可能因素均能导致一定程度的不适感。在皮肤上施加助剃剂,能使伴随着湿法剃须装置的不适感以及其它问题得到缓解。所述助剃剂可在剃须之前、剃须期间或者剃须之后敷复。但是预先或事后使用助剃剂存在许多问题。预先敷复的助剃剂会蒸发消失或者由于剃刀的反复剃刮而带离敷复部位,而事后敷复的助剃剂在剃须期间又起不到予期作用,不论是预先敷复还是事后敷复助剃剂,都给剃须过程增加了额外步骤。
已经有多种建议,将诸如润滑剂、胡须软化剂、剃刀清洁剂、药剂、美容剂或它们的混合物放在剃须刀中作为剃须助剃剂,其方法可为:用摩擦力将剃须助剃剂紧固在剃须刀的凹槽中,把剃须助剃剂直接做在剃须刀的一个或多个成形的聚合物构件之中,把剃须助剃复合物粘贴在剃须刀上,还可以在剃须助剃剂及剃须刀之间采用机械连接。有人曾将一种水溶性剃须助剃剂聚乙烯氧化物与一种非水溶性材料聚苯乙烯聚合物混合,从而形成一种非水溶性聚合物和水溶性助剃剂的复合物。这种复合物已经被安置在单刀片或多刀片的剃须刀和剃须夹头结构上,并与一个或多个剃须刃相邻。所述水溶性助剃剂遇水就从该复合物中溶出到皮肤上。
本发明的一个目的是:提供一种剃须装置,它包括至少一把刀片以及一个助剃复合物。所述复合物有一个面与使用者靠近刀片刃口的皮肤接触。该剃须装置可以是夹头可拆卸形式,因而能联接在剃须刀柄上或者从刀柄上拆下;该剃须装置也可以是与刀柄做成一体的,当一把或多把刀片用钝之后,整个剃须刀就被废弃。一个或多个刀片刃口与皮肤接触的外表面,构出剃须的外形。所述皮肤接触表面具有一个助剃复合物,该复合物是一种非水溶性基体混合物,它包括有效数量的助剃材料以及有效数量的非水溶性香精油材料,在剃须期间,被水溶出的助剃剂从复合物中溶出,与此同时,所述非水溶性的香精油材料也释放出来,从而在每平方厘米皮肤表面上敷复至少1毫微克左右香精油。
助剃复合物最好由适于挤出成形的材料制成,并包括:占重量20-40%的基体材料,占重量40-75%的可用水溶出的助剃材料,以及占重量2-20%的香精油材料。所述助剃复合物还可包括一种释放增强剂,该增强剂可从聚乙烯乙二醇、甲氧基聚乙烯乙二醇、甲基纤维素和羰基聚甲烯一类物料中选用。
适用的非水溶性基体材料可包括:例如,聚乙烯、聚丙烯、聚苯乙烯和聚乙酰,适用的助剃材料可包括:聚乙烯氧化物、聚乙烯吡咯烷酮、(polyvinyl pyrrolidone)聚丙烯酰
Figure 911093834_IMG2
、羟基丙基纤维素、聚乙烯咪唑啉,聚羟乙酸异丁稀酸酯(polyhydroxyethylmethacrylate)、硅氧烷共聚物、蔗糖硬脂酸酯、维生素E、羟泛酸以及芦荟,适用的香精油材料包括薄荷醇、丁子香酚(丁香油)、桉树脑(桉树油和白千层油)、黄樟脑(黄樟油)以及水杨酸甲酯(白珠树油)。
在一些特殊的实施例中,助剃复合物是一种适于挤出成形的聚合材料的复合物,所述复合物包含水溶和非水溶性材料,成比例的水溶性和非水溶性材料的性质应满足如下条件:无论是制成初期,或是在有效数量的水溶性物质已经被释放掉之后,此复合物均具有足够的机械强度。
本发明的另一个目的是:提供制造一种成形的助剃复合物的方法,所述复合物用于湿法剃须的剃须装置,它包括:非水溶性聚合材料的基体,有效数量的可用水溶出的助剃材料,以及有效数量的非水溶性香精油材料;所述方法包括以下步骤:形成一种由所述非水溶性聚合材料和可用水溶出的助剃材料制成的掺和料;在温度低于100℃状态加入所述非水溶性香精油微粒以便使所述掺和料成为一种混合物,在加入香精油不到一分钟时间内挤出该复合物从而做出所述成形的助剃复合物。
下面结构附图,介绍几个特殊实施例,以便对本发明的其他特点和优越性有更清楚的了解;其中:
图1是一个本发明剃须刀装置的透视图。
图2是沿图12-2线剖切的断面图。
图3是另一个本发明剃须刀装置的断面图。
图1和2所示的剃须装置10包括刀架构件12和防护结构16,所述构件12由耐冲击聚苯乙烯模压成,并具有做成一体的配合槽14以便与剃刀柄相连,而所述防护结构16形成一个朝前横向伸出的皮肤接触面18。在刀架12的上表面上安置着钢质的主刀片20和尾随刀片24,它们分别具有锋利的刃口22和26,还安置着一个铝质的隔离构件28,以便使刀片20和24处于隔开状态。罩壳构件30也由耐冲击聚苯乙烯模压成,它包括主体部分32和一个前缘38,所述主体部分32确定了皮肤接触面34,该接合面在两个前伸端壁36之间横向延伸,而所述前缘38安置在刀片刃口26的后部,做成整体的固定部分40从横向的主体部分32向下伸出,穿过刀片20和24、隔离构件28以及刀架12的孔洞,将罩壳30、刀片20和24以及隔离构件28固定在刀架12上。在皮肤接触面34上粘贴着助剃复合物42。
图3所示的剃须装置50的类型在雅各布松(Jacobson)的美国专利4,586,255中可以见到,它包括具有前部54和后部56的主体52。在主体52中弹性紧固着防护构件58、主刀片60和尾随刀片62,一个助剃复合物做成长插入构件64的形状,靠摩擦力固定在后部56的开口66中。
下面举几个实例进行介绍,它们并不对本发明起限制作用。

实例2:
一种混合物,其重量百分比组成为:耐冲击聚乙烯约32%,一种水溶性聚合物(特别是一种混合料,它包括占重量60%的分子量为5,000,000的聚氧凝结剂聚乙烯氧化物;以及占重量40%的分子量为300,000的聚氧WSRN-750聚乙烯氧化物)52%,水溶性聚乙烯乙二醇9%(分子量为4,500),以及薄荷醇6%。该混合物还含有少量染料和抗老化添加物。这种混合物通过一种压出机挤出。薄荷醇以微粒状(颗粒尺寸约4,100微米)加入混合物,并与其它构成物料混合。水冷供料区域(送至圆筒)的温度约为17℃,中间圆筒的温度约为120℃和160℃,而模具温度约为160℃。圆筒压力约为2,700磅/吋2,而模具压力约为1,900磅/吋2。被挤出的条状物件的横截面形状如图3所示。然后从被挤出条状构件上切下构件64,固定在剃须部件50的开口66中。所得到的挤出构件64是坚固的,还具备一种有吸引力的外观,做成的夹头50具有良好的综合剃须性能。
实例3:
一种混合物,其重量百分比组成为:而冲击聚乙烯约31%,一种水溶性聚乙烯氧化物50%,一种水溶性聚乙烯乙二醇9%(分子量为4,500),以及薄荷醇10%。该混合物通过一种压出机挤出。薄荷醇以微粒状加入混合料,与其它构成物料混合,并且挤压成形时在挤压系统中的停留时间不到1分钟。供料区域(送至圆筒)的温度约为120℃,圆筒温度约为160℃,而模具温度约为160℃。被挤出的条状构件的横截面形状如图3所示。然后从被挤出条状构件上切下构件64,固定在剃须部件50的开口66中。所得到的挤出构件64坚固而且具备一种有吸引力的外观,做成的夹头50具有良好的综合剃须性能。
实例4:
一种混合物,其重量百分比组成为:耐冲击聚乙烯约27%,水溶性聚乙烯氧化物45%,水溶性聚乙烯乙二醇8%(分子量为4,500)以及薄荷醇20%。该混合物通过一种压出机挤出,薄荷醇以微粒状加入混入料之中,与其它构成物料混合,并且挤出成形时在挤压系统中的停留时间不到1分钟。供料区域(送至圆筒)的温度约为80℃,圆筒温度约为160℃,而模具温度约为180℃。被挤出的条状构件的横截面形状如图3所示。然后从被挤出条状构件上切下构件64,固定在剃须部件50的开口66中。所得到的挤出构件坚固而且具备一种有吸引力的外观,做成的夹头50具有良好的综合剃须性能。
不溶于水的薄荷醇与聚乙烯氧化物润滑剂一起从夹头插入构件64中释放出来,以便减少剃须中产生的疼痛程度、增加舒适感并全面地改善剃须质量。从插入构件64中所得到的薄荷醇数量约为3%,一部分薄荷醇与聚苯乙烯结合,在聚乙烯氧化物和其它可用水提取的材料完全从插入构件64中溶出之后,插入构件中薄荷醇最初量的大约20%与聚乙烯残留物一起保留下来。
此装置为每平方厘米皮肤提供大约15毫微克薄荷醇,所提供的薄荷醇中大约三分之二是独立存在的。在剃须期间,含有大约3%薄荷醇的插入构件64能为脸部释放大约5微克薄荷醇(用气相层析/质谱测定法、皮肤表面的酒精提取分析法进行测定)。在冲洗之后,所述释放出的薄荷醇中的大约三分之二,即3.3微克保留在皮肤上。
