  • Packaging and docking system for non-contact chemical dispensing
    Patent number: 11401084
    Abstract: A chemical dispensing system can include a docking stating that receives a reservoir containing chemical to be dispensed. The reservoir may have one or more retention tabs which are movable from a first position in which each tab extends radially across at least a portion of the bore to a second position in which each tab is offset relative to the bore. A user can engage the reservoir with the docking station, causing the one or more retention tabs on the reservoir to engage with one or more corresponding retention tab receiving regions. This can cause each retention tab to move from the first position to the second position, thereby dispensing chemical from the bore through a discharge aperture of the docking station. In this way, the contents of the reservoir may be dispensed without the user coming into physical content with the chemical in the reservoir.
