  • Patent number: 6058827
    Abstract: A tea flushing device comprises a cup body, a filtering net, a buckling disk, and a water stopper. The bottom of the cup body is installed with a long hole for being buckled and penetrated by a buckling disk so that the cup body and the buckling disk may move upwards and downwards with respective to one another. Other than protruding from the through hole installed on the buckling disk, in a plurality of foot plates, a water stopper is installed at the through hole of the bottom of the cup body. The water stopper may be a metal rolling ball with a elastic rubber water stop pad or be formed a water stopping block and guide rod. Therefore, as the tea flushing device is flatly placed on a plane, by the supporting of the foot plate, the buckling disk will drop down naturally so that the water stopper will seal the through hole. Thus, the operation of flushing tea within the cup can be performed. If desired, the tea flushing device is only necessary to be placed at a proper container.

  • Patent number: 6055900
    Abstract: The present invention provides a novel splash guard which is positioned in a brewing funnel in close proximity to the handle of the funnel. The splash guard is a curved structure which extends over a portion of the mouth of the brewing funnel. The splash guard extends over a portion of the mouth of the brewing funnel, but not to such an extent as to interfere with the spraying of water into the brewing funnel, or the placing of filter supports, filters or brewing substance into the brewing funnel. The splash guard functions to deflect a slurry of water, brewing substance and brewed beverage in the funnel which is displaced toward the handle, and to direct the slurry back into the funnel instead of splashing out of the brewing funnel.

  • Patent number: 5298267
    Abstract: A conformable, self-aligning, high extraction efficiency coffee filter pack capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk coffee and a paper filter under identical brewing conditions, but which exhibits substantially consistent pot-to-pot brew strength for any given automatic drip coffee maker. The preferred filter pack is formed from two layers of flexible material which are secured to one another about their outermost periphery with a predetermined quantity of roast and ground coffee housed within a brew chamber formed between the two layers. The brew chamber exhibits a maximum volume between about 25 percent and about 300 percent greater than the volume of the dry roast and ground coffee contained therein. The discharge flow rate from the brew chamber is slower than the inlet flow rate into the brew chamber to permit a buildup of water and flooding of the brew chamber.
