- The invention relates to brewed beverages and in particular to beverage brewing cartridges, methods of making beverage brewing cartridges, and tools for making beverage brewing cartridges.
- Beverage brewing cartridges typically contain ground brewing material, through which water is flowed to brew a beverage. For example, espresso beverages are made by forcing high-pressure water through tightly packed, finely ground coffee. The ground coffee is contained in a holder commonly called a “portafilter”, or into a pre-packaged espresso cartridge. High-pressure water is forced through the ground coffee and beverage is extracted in small, concentrated amounts. Many espresso drinkers prefer the simplicity of using the espresso cartridges, but are limited in the selection of ground coffee to varieties available in the pre-packaged espresso cartridges, and the cost of brewing beverages from disposable, individual cartridge is great, both economically and in terms of impact on the environment.
- According to an aspect of the invention, a beverage brewing cartridge includes a cartridge base, and a cartridge plug. The cartridge base includes a sidewall, a fillable end having an opening, and a closed end. The cartridge plug is configured to close off the opening of the fillable end of the cartridge base. The cartridge base sidewall can be, for example, frustoconical in shape. The closed end of the cartridge base can be sealed, for example, with foil. The cartridge plug can include ports configured to allow fluid to flow from the cartridge. For example, the ports can include weakened areas configured to burst under pressure, thereby allowing fluid to flow from the cartridge. The cartridge plug or the opening of the fillable end of the cartridge base can include an annular recess, and the other can include a corresponding annular ridge, configured for mutual mating contact. The beverage brewing cartridge can also include a circumferential lip above the annular recess. The circumferential lip can include gaps configured to allow the circumferential lip to collapse during insertion of the cartridge plug into the opening of the fillable end of the cartridge base.
- According to another aspect of the invention, a method of constructing a brewing cartridge includes placing the cartridge base of the beverage brewing cartridge on a cartridge seat of a cartridge tool with the closed end of the cartridge base against the cartridge seat. The cartridge base is retained against the cartridge tool using a cartridge lock. A portion of brewing material is scooped and poured into the cartridge base through a mouth of the cartridge lock and the opening of the fillable end of the cartridge base. The brewing material is then tamped into the cartridge base. The cartridge plug is positioned above and aligned with the opening of the fillable end of the cartridge base. The cartridge plug is then seated into the opening of the fillable end of the cartridge base to close the opening of the fillable end of the cartridge base, thereby completing construction of the brewing cartridge. The method can also include releasing the cartridge lock from the cartridge base, and removing the brewing cartridge from the cartridge tool.
- Scooping the portion of brewing material and tamping the brewing material into the cartridge base can include using a combination scooping/tamping tool. The method can also include leveling the portion of brewing material using a leveling arm of the combination scooping/tamping tool, prior to pouring the scooped brewing material.
- Positioning the cartridge plug above and aligned with the opening of the fillable end of the cartridge base can include engaging a first guide element on the cartridge plug with a second guide element on an end of the combination scooping/tamping tool, and inserting the end of the combination scooping/tamping tool into an access mouth of the cartridge lock.
- The method can also include, prior to placing the cartridge base on the cartridge seat of the cartridge tool, obtaining the cartridge base, and sealing an end of the cartridge base to form the closed end of the brewing cartridge base. For example, sealing the end of the cartridge base can include applying foil to the end of the brewing cartridge base. Seating the cartridge plug into the opening of the tillable end of the cartridge base can include engaging a ridge into a recess.
- According to another aspect of the invention, a beverage brewing cartridge construction kit, configured to construct a brewing cartridge, includes the cartridge tool and the cartridge lock. The cartridge tool can include a cartridge seat. The beverage brewing cartridge construction kit can also include a combination scooping/tamping tool. The combination scooping/tamping tool can include a levelling arm and/or a cartridge plug guide element.

To provide a measured portion of brewing material, the method can also include leveling the portion of brewing material using a leveling arm of the combination scooping/tamping tool, prior to pouring the scooped brewing material. This leveling arm can take any shape.
- Positioning the cartridge plug above and aligned with the opening of the fillable end of the cartridge base can include engaging a first guide element on the cartridge plug with a second guide element on an end of the combination scooping/tamping tool, and inserting the end of the combination scooping/tamping tool into an access mouth of the cartridge lock. These guide elements can take the form of any mating structures, such as a corresponding indentation or hole and pin.
- The method can also include, prior to placing the cartridge base on the cartridge seat of the cartridge tool, obtaining the cartridge base, and sealing an end of the cartridge base to form the closed end of the brewing cartridge base. For example, sealing the end of the cartridge base can include applying foil to the end of the brewing cartridge base. Alternatively, a cover can be coupled to the cartridge base to close the end. Seating the cartridge plug into the opening of the fillable end of the cartridge base can include engaging a ridge into a recess. Alternatively, these elements can be screwed together, friction fit, or coupled in any other suitable manner.
- According to another aspect of the invention, a beverage brewing cartridge construction kit, configured to construct a brewing cartridge, includes the cartridge tool and the cartridge lock. The cartridge tool can include a cartridge seat. The beverage brewing cartridge construction kit can also include a combination scooping/tamping tool. The combination scooping/tamping tool can include a scoop and a tamper, as well as a levelling arm and/or a cartridge plug guide element.
- The invention has been described by way of example and in terms of preferred embodiments. However, the present invention as contemplated by the inventor is not strictly limited to the particularly disclosed embodiments. To the contrary, various modifications, as well as similar arrangements, are included within the spirit and scope of the present invention.
