  • Patent number: 6170708
    Abstract: A dual-dispenser bottle having middle ornamental window is provided. The bottle is vertically divided into top, middle and bottom sections and both the top and the bottom sections are further horizontally divided into two chambers. The two top chambers are provided with a mouth each for two dispenser heads to connect thereonto. The middle section defines an inner space through which two spaced pipes separately in alignment with the mouths vertically extend. The two bottom chambers are separately communicable with the two top chambers via the two spaced pipes. Whereby the top and the bottom chambers at two sides of the bottle form two independent vertical spaces for the bottle to contain two different fluids at the same time. The inner space of the middle section may have, for example, a dual-liquid ornament provided therein to make the bottle an ornamental article very practical for use.

  • Patent number: 6135323
    Abstract: A bottle for containing fluid, such as milky lotion, includes a top and a bottom section separated from each other by a middle partition connected to and between them. The top section is integrally formed of two spaced pipes, upper ends of which form two mouths to receive two dispensers, and lower ends of which are tightly joined with two holes on the middle partition to communicate external space with two closed chambers formed in the bottom section. Such bottle can therefore be used to contain two different types of milky lotion at the same time to effectively reduce the number of and the space occupied by bottles in, for example, a toilet room. Moreover, a dual-liquid ornament can be contained in the top section of the bottle to give the same additional value as an ornament. The bottle may have a downward protruded bottom center about which the bottle can be easily turned or swung to cause dynamic changes in the dual-liquid ornament.
