  • the inventors have recognized drawbacks related to the use of typical juicers such as centrifugal juicers, masticating juicers, and conventional press juicers. More specifically, these types of juicers are exposed to food matter and extracted liquids during use. Due to the use of complex mechanisms within these juicers, crushed and/or pulped food matter left after juice extraction may become entrapped in the machinery of these juicers, making cleanup difficult. If not completely cleaned, undetected food matter left behind within a juicer may become a food safety hazard. Furthermore, typical juicers may require difficult and/or time consuming preparation of food matter in addition to oftentimes being complex to operate.
  • a juicing system capable of providing a variety of juices and/or juice blends without the need to prepare individual ingredients as well as dealing with the complex operation and cleaning associated with a typical juicing system.
  • a juicing system in which food matter contained within individual juicer cartridges that are positioned within and pressed by a corresponding juicer may afford simple operation and cleanup.
  • such a juicing system may press one or more juicer cartridges containing single or multiple ingredients to create one or more servings of a custom juice blend while minimizing and/or eliminating contact between the juicer and the associated food matter and/or extracted juice.
  • juice and/or food matter come into contact with a portion of a juicer are also contemplated.
  • a juicer includes a pressing chamber sized and shaped to receive one or more juicer cartridges containing food matter.
  • the pressing chamber may include one or more displaceable pressing surfaces that are associated with the pressing chamber and which may be driven by a suitable drive mechanism during actuation, as will be described in more detail below. Displacement of the one or more pressing surfaces relative to the pressing chamber may compress the one or more juicer cartridges in the pressing chamber in order to apply pressure to the food matter contained therein and extract juice from the food matter.
  • a pressing chamber may include a juicer outlet that is configured to receive an outlet of a juicer cartridge positioned within a pressing chamber of the juicer.
  • the juicer outlet may be constructed and arranged such that the outlet of the juicer cartridge extends beyond an exterior edge of the juicer outlet from the pressing chamber to an exterior of the juicer.

  • such a configuration may reduce the pressure associated with a stream of juice exiting the juicer cartridge through the outlet during initial opening of the juicer cartridge to be reduced in discrete stages during opening of the juicer cartridge which, may therefore further help to reduce splashing, foaming, or other undesirable effects associated with conventional burs table seal designs in which the pressure release is more violent and/or unpredictable.
  • the pressure within the cartridge may be reduced by some amount due to the relatively incompressible nature of liquids, and since the secondary seal is weaker than the primary seal, the secondary seal may open without requiring additional pressure and/or compression be applied to the juicer cartridge.

  • Suitable materials to form a burstable seal in a juicer cartridge include, but are not limited to, thermally activated adhesives. Such adhesives form an adhesive bond only in areas that are appropriately treated with heat and pressure after the adhesive is applied. In this manner, thermally activated adhesives may allow for simple control of the seal geometry during manufacturing of juicer cartridges. For example, a heated stamp, which may be shaped in accordance with a desired geometry of the burstable seal, may press together layers of liquid impermeable material that have been coated with a thermally activated adhesive to form the seal. Further, a thermally activated adhesive may be beneficial as it may allow for careful control of the bond strength via control of the temperature of the stamp, or press, used to activate the adhesive. Accordingly, in some embodiments the bonding temperature used to bond a thermally activated adhesive to form a burstable seal may be carefully controlled to provide a consistent seal strength.

In other embodiments, the parameters of the burstable seal may be tuned to the specific type of food matter contained within the juicer cartridge, or any other factors relating to the extraction and/or dispensing of juice, as the disclosure is not limited in this regard.
