  • Patent number: 11970384
    Abstract: A modular dispenser stand includes a height adjustable frame and a supporting frame. The height adjustable frame includes a plurality of telescopic legs each adapted for selectively adjusting its length, and a leg locker unit provided at each of the telescopic legs to selectively lock up said telescopic leg at a predetermined length, wherein the telescopic legs are spaced apart with each other to define a storage space therewithin. The supporting frame includes an upper support coupled at upper ends of the telescopic legs for supporting a water bottle on the upper support, and a base support detachably coupled at the telescopic legs below the upper support to define the storage space between the upper support and the base support. Accordingly, the telescopic legs are selectively reduced their lengths to drop down the upper support and are selectively increased their lengths to increase the storage space.

  • Patent number: 6921003
    Abstract: A water bottle cap includes a cap body including a sealing platform and a surrounding sealing wall extended from the sealing platform for sealedly enclosing around an opening of a water bottle, and a water dispensing arrangement including a guiding channel extended from the sealing platform of the cap body and defining a water passage, and a sealing member, which is integrally mounted at the guiding channel to sealedly close the water passage defining a breakable edge portion and a retaining edge portion. Therefore, when the water bottle is installed on the water dispenser, a spigot adapter of the water dispenser is plugged into the water passage to break the sealing member at the breakable edge portion thereof while the retaining edge portion of the sealing member is remained to attach to the guiding channel.
