  • Patent number: 10549298
    Abstract: A pivot-to dispense soap pump includes an actuator that dispenses soap when actuated. The actuator is configured to move downward when actuated by user input. The downward movement may be in either one of a linear movement, maintaining the actuator is a horizontal orientation, or a pivoting movement about a pivot point. The pivot point is located on a distal end of the actuator, which is opposite the nozzle. The pivoting motion allows a user to depress the actuator proximate to the nozzle, thereby allowing the user to dispense soap into the same hand used to actuate the actuator. As a result, efficient, one-handed soap pumping and dispensing is enabled.

One or more air passageways between the air cylinder and a liquid-air mixing chamber are configured to impart rotation to an airstream passing from the air cylinder to the mixing chamber to increase turbulent mixing of the air and liquid in the mixing chamber. The liquid cylinder is axially aligned with the air cylinder to provide a low profile pump which does not require a dip tube or sleeve to communicate with the bottom of the liquid source when used in an inverted application wherein the foam pump is positioned below the source of liquid. A resilient valve member in the liquid outlet is biased to close on its own to prevent leaking in the event the air and liquid pistons do not fully return to the home position.

  • Patent number: 9731309
    Abstract: A foam dispensing cap includes a cap body having a ceiling wall and a cylindrical side wall, and a partition member. An ejection pipe is erected on the upper surface of the ceiling wall. An air chamber is in the space below the ceiling wall. A liquid entry opening is in the partition member. In the air chamber, an air passage for flowing air within the air chamber and a liquid flow path for flowing the content liquid, which has passed through the partition wall and entered the air chamber, communicate with each other. The air passage and the liquid flow path are formed to merge, and a region ranging from the point of merging to the ejection pipe defines an air-liquid mixture flow path. When the squeeze container is tilted and squeezed, the content liquid is ejected in a foamy state from the leading end of the ejection pipe.
