    • A toothbrush with an integral toothpaste dispenser has a handle portion and a toothbrush portion. A commercially available toothpaste tube is opened at one end and contained within a central aperture of the handle of the integral toothbrush. Toothpaste from the toothbrush tube is discharged into a channel contained within the toothbrush portion and exits between the toothbrush bristles through a non-return valve positioned close to a bristle exit aperture. Toothpaste is squeezed by upward movement of a pedestal supporting the toothpaste tube when the user turns a knob on the bottom of the handle. The toothpaste tube is supported by a vertical support tube within the central aperture of the handle, producing an accordion-like, uniform, progressive toothpaste tube collapse. The non-return valve is only open during toothpaste delivery and thereby prevents toothpaste spills. The close proximity between the toothpaste exit aperture and the non-return valve enables the toothpaste to remain moist between brushings. Toothpaste residue between the non-return valve and the bristle exit aperture is readily rinsed away during cleaning to provide a hygienically clean toothbrush.
    • 具有整体牙膏分配器的牙刷具有手柄部分和牙刷部分。 市售的牙膏管在一端打开并且包含在整体牙刷的手柄的中心孔内。 来自牙刷管的牙膏被排放到包含在牙刷部分内的通道中,并通过靠近刷毛出口孔定位的止回阀在牙刷刷毛之间离开。 当用户转动手柄底部的旋钮时,牙膏被支撑牙膏管的基座的向上运动挤压。 牙膏管由手柄的中心孔内的垂直支撑管支撑,产生手风琴状均匀的渐进式牙膏管塌陷。 止回阀仅在牙膏输送期间打开,从而防止牙膏溢出。 牙膏出口孔和止回阀之间的紧密接近使得牙膏在刷子之间保持湿润。 在清洁期间,止回阀和刷毛出口孔之间的牙膏残留物容易被冲洗掉,以提供卫生洁净​​的牙刷。
