Abstract: The method of the present invention is directed to the storage and dispensing of a peroxide containing tooth whitening composition. During storage and subsequent use the composition in the storage chamber must be maintained segregated from the applicator surface. This is accomplished by delivering the peroxide containing tooth whitening composition from the storage chamber through a delivery channel having a length and a cross-sectional diameter sufficient to preclude the migration of moisture and the enzyme catalase from the application surface to the storage chamber. The composition is applied to teeth by means of bristles, a sponge surface or fibrillated surface. This applicator can be used with both aqueous and non-aqueous peroxide containing tooth whitening compositions.
Abstract translation: 本发明的方法涉及含过氧化物的牙齿增白组合物的储存和分配。 在储存和随后使用期间，储存室中的组合物必须保持与施用器表面分离。 这是通过将来自储存室的含过氧化物的牙齿增白组合物通过具有足以防止水分和酶过氧化氢酶从施用表面迁移到储存室的长度和横截面直径的输送通道来实现的。 组合物通过刷毛，海绵表面或原纤化表面施加到牙齿上。 该施用器可以与含水和非水过氧化物含有牙齿美白组合物一起使用。
