Beverage formation apparatus and method using sonic energy
View Patent ↗Apparatus and method for forming beverages using a beverage cartridge and sonic energy. A cartridge may include a sonic receiver, such as a feature that extends into an interior space of the cartridge and is arranged to receive a sonic emitter that introduces sonic energy into the interior space. The sonic receiver may be excited by sonic energy, which causes the sonic receiver to itself introduce sonic energy into the cartridge.
1. A method of forming a beverage, comprising:
providing a beverage cartridge arranged for use in a beverage forming machine to make a beverage, the cartridge including a container having a closed interior space and a beverage medium located in the interior space;
introducing liquid into the closed interior space of the cartridge;
using a sonic emitter adjacent to the cartridge to provide sonic energy to an exterior of the cartridge, the sonic emitter being adjacent to the cartridge only when the cartridge is held in the beverage forming machine;
transmitting the sonic energy into the closed interior space of the cartridge while liquid introduced into the closed interior space is present in the cartridge; and
forming a beverage by simultaneous interaction of the liquid and sonic energy with the beverage medium; wherein
the cartridge includes a sonic receiver attached to the container and arranged to transmit sonic energy from the sonic emitter located outside of the closed interior space into the interior space for interaction with the beverage medium; and
the sonic receiver includes a depression in a sidewall of the container.
2. The method of claim 1 , wherein the sonic receiver includes an acoustically compliant portion of the cartridge that is excited by sonic energy.
3. The method of claim 1 , wherein the step of introducing liquid includes:
piercing the container; and
injecting liquid into the closed interior space.
4. The method of claim 1 , wherein the step of forming a beverage includes:
causing materials to pass through a filter in the cartridge that would not pass through the filter in the absence of the sonic energy.
5. The method of claim 1 , wherein the step of forming a beverage includes:
forming a beverage that has a higher level of dissolved and/or suspended materials than would be present in the absence of the sonic energy.
6. The method of claim 1 , wherein the sonic emitter includes an ultrasonic probe.
7. The method of claim 1 , wherein the beverage is a coffee beverage and the step of forming the beverage includes:
forming a coffee beverage with a turbidity and/or a level of total dissolved solids that is higher than would be present in the absence of the sonic energy.
8. The method of claim 1 , wherein the step of transmitting includes:
exciting an acoustically compliant portion of the cartridge with the sonic energy.
9. The method of claim 1 , wherein the step of transmitting includes:
causing flow of beverage medium and liquid in the interior space by exposing the interior space to the sonic energy.
10. The method of claim 1 , wherein using a sonic emitter adjacent to the cartridge to provide sonic energy to an exterior the cartridge comprises contacting the sonic emitter with the beverage cartridge.
11. The method of claim 1 , wherein the beverage forming machine includes the sonic emitter, and the sonic emitter is located at a cartridge receiver and is positioned to be adjacent the cartridge when the cartridge is in the cartridge receiver.
