    • Disclosed are devices for dispensing air treatment chemicals. There is a substrate bearing a first volatile air treatment chemical that is capable of being dispensed from the substrate when the substrate is heated, and an indicator unit holding a volatile indicator chemical separate from the first volatile air treatment chemical such that the volatile indicator chemical is capable of being dispensed from the unit when the unit is heated. The extent of dispensing of the first volatile air treatment chemical can be indicated by a visible cue whose appearance results from the dispensing of the volatile indicator chemical. In one form the unit also holds a second air treatment chemical. In another the indicator unit is a replaceable cartridge positionable more remote from the heater than the substrate.

    • A candle assembly includes a melting plate having a capillary pedestal, a wick holder that fits over the capillary pedestal, a wick that is carried by the wick holder, and a fuel element that fits over the wick and wick holder and rests on the melting plate. The fuel element includes a duct therethrough for receiving the wick holder. The fuel element is adapted to prevent improper insertion of the wick holder into the duct. The duct is adapted to facilitate successful initial ignition and sustained burn of the wick by having a width that is selected to ensure that melted fuel material engages the wick when dripping down the duct. A capillary well disposed between the wick holder and the capillary pedestal may be adapted to promote a successful relight after an initial burn of the candle assembly. A candle holder, such as including the melting plate supported by a base, may be adapted to promote laminar air flow thereacross during a burn in a substantially calm atmospheric environment.
    • 蜡烛组件包括具有毛细管基座的熔化板,配合在毛细管基座上的芯保持器,由芯保持器承载的灯芯和装在灯芯和灯芯支架上并靠在熔化板上的燃料元件 。 燃料元件包括用于接纳油绳支架的通道。 燃料元件适于防止芯座不正确地插入管道中。 管道适于促进成功的初始点火并且通过具有选择的宽度来持续燃烧油绳,以确保当向下滴下管道时熔化的燃料与油绳接合。 在芯保持器和毛细管基座之间布置的毛细管孔可以适于在蜡烛组件的初始燃烧之后促进成功的重新点亮。 诸如包括由基座支撑的熔化板的烛台可以适于在基本平静的大气环境中的燃烧期间促进其间的层流气流。

    • An improvement in a sealed pouch made of molecularly-orientable polymeric film that is sealed along peripheral edge margins is disclosed. The pouch defines a sealed cavity for containment of a fluid. The pouch also defines a sealed fluid-discharge spout that is in fluid communication with the fluid cavity. The pouch further defines a seam disposed between the fluid cavity and the spout. The improvement comprises at least three essential features. One such feature is that a portion of the polymeric film which defines a fluid-discharge end of the spout is molecularly-oriented in a preselected direction. Another such feature is that a portion of the seam defines a slit disposed transverse to the preselected direction. Still another feature is that a portion of the sealed pouch peripheral edge margin in the vicinity of the fluid-discharge end of the spout defines a tear-initiating notch oriented in the preselected direction.
    • 公开了一种由沿着边缘边缘密封的可分子取向的聚合物膜制成的密封袋的改进。 该袋限定用于容纳流体的密封腔。 袋还限定了与流体腔流体连通的密封流体排放喷口。 袋进一步限定了布置在流体腔和喷嘴之间的接缝。 改进包括至少三个基本特征。 一个这样的特征是限定出口的流体排放端的聚合物膜的一部分在预选的方向上被分子取向。 另一个这样的特征是接缝的一部分限定了横向于预选方向设置的狭缝。 另一个特征是在喷嘴的流体排出端附近的一部分密封的袋周缘边缘限定了沿预选方向定向的撕裂起始缺口。
