Abstract

A bottom fillable espresso cartridge base and apparatus and method for filling and plugging the bottom of the espresso cartridge base. The espresso cartridge base includes an open bottom and a press in bottom plug. The top of the espresso cartridge may be sealed by a foil lid or the like, or be open and an adhesive attachable lid may be included for attachment by a user. A first method utilizes a hand held multi-function tool including a cartridge holder with a holder lid to capture the espresso cartridge, and a bottom tamper and plug seating arm. A second method utilizes a stationary base residing on a flat surface, a cartridge holder to retain cartridges on the base, and individual tools to fill and tamp brewing material in the cartridge, and to attach the bottom plug to the cartridge.

First claim

I claim:

1. A method for constructing an espresso cartridge, the method comprising:
placing a frustoconical shaped brewing cartridge base onto a cartridge seat of a tool base, a closed cartridge base top against the cartridge seat, the cartridge base top having a larger diameter than an open cartridge base bottom opposite the cartridge base top;
attaching a cartridge lock to the tool base to retain the cartridge base against the tool base;
using a scoop end of a scoop/tamper/seating tool to scoop a portion of brewing material;
pouring the brewing material through a mouth of the cartridge lock and the open cartridge base bottom, into the cartridge base;
using a tamping end opposite to the scoop end of the
scoop/tamper/seating tool to tamp the untamped brewing material into the cartridge base;
positioning a bottom plug above the cartridge base bottom and aligned with the cartridge base bottom;
using a tamping end opposite to the scoop end of the
scoop/tamper/seating tool to seat the bottom plug into the open cartridge base bottom; and
removing the finished cartridge from the tool.

2. The method of claim 1 , further including after using the scoop end of the scoop/tamper/seating tool to scoop a portion of brewing material, leveling the brewing material to obtain a proper amount of brewing material for the espresso cartridge.

3. The method of claim 2 , wherein leveling the brewing material comprises sliding a level across the scoop.

4. The method of claim 3 , wherein sliding a level across the scoop comprises sliding a level retained to slide in a slot in the scoop/tam per/seating tool.

5. The method of claim 1 , wherein aligning the bottom plug with the cartridge base bottom comprises:
engaging a guide hole of the bottom plug with a guide hole pin on the tamping end of the scoop/tamper/seating tool; and
inserting the tamping end of the scoop/tamper/seating tool into an access mouth of the cartridge lock.

6. The method of claim 1 , further including prior steps of:
obtaining a fillable espresso cartridge, the espresso cartridge comprising:
a cartridge base comprising:
frustoconical shaped walls;
a cartridge base top selected from a sealed top or a sealable top; and
an open cartridge base bottom having a smaller diameter than the cartridge base top; and

the bottom plug configured to insert into the open cartridge base bottom, the bottom plug configured to release brewed beverage through the bottom plug during brewing; and

if unsealed, sealing the cartridge base top.

7. The method of claim 6 , wherein the cartridge base top is sealed by foil.

8. The method of claim 6 , further including foil and adhesive for attaching the foil to the cartridge base top to seal the cartridge base top.

9. The method of claim 6 , wherein the bottom plug includes ports allowing the brewed beverage to release from the cartridge during brewing.

10. The method of claim 6 , wherein the bottom plug includes weakened areas configured to burst during brewing allowing the brewed beverage to release from the cartridge during brewing.

11. The method of claim 6 , wherein the bottom plug includes an annular recess and the open cartridge base bottom includes an interior annular ridge, and pressing the bottom plug into the open cartridge base bottom comprises engaging the interior annular ridge into the annular recess.

12. The method of claim 6 , wherein the bottom plug includes a circumferential lip above the annular recess, and the circumferential lip includes gaps allowing the circumferential lip to collapse during insertion of the bottom plug into the open cartridge base bottom.

13. A method for constructing an espresso cartridge, the method comprising: obtaining a fillable espresso cartridge, the espresso cartridge comprising:
a cartridge base comprising:
frustoconical shaped walls;
a cartridge base top selected from a sealed top or a sealable top; and
an open cartridge base bottom having a smaller diameter than the cartridge base top; and

a bottom plug configured to insert into the open cartridge base bottom, the bottom plug configured to release brewed beverage through the bottom plug during brewing; and
if unsealed, sealing the cartridge base top, placing the frustoconical shaped brewing cartridge base onto a cartridge seat of a tool base, the sealed cartridge base top against the cartridge seat, the cartridge base top having a larger diameter than the open cartridge base bottom opposite the cartridge base top;
attaching a cartridge lock to the tool base to retain the cartridge base against the tool base;
using a scoop end of a scoop/tamper/seating tool to scoop a portion of brewing material;
leveling the brewing material to obtain a proper am aunt of brewing material for the espresso cartridge;
pouring the brewing material through a mouth of the cartridge lock and the open cartridge base bottom, into the cartridge base;
using a tamping end opposite to the scoop end of the scoop/tamper/seating tool to tamp the untamped brewing material into the cartridge base;
positioning a bottom plug above the cartridge base bottom and aligned with the cartridge base bottom;
using a tamping end opposite to the scoop end of the scoop/tamper/seating tool to seat the bottom plug into the open cartridge base bottom; and
removing the finished cartridge from the tool.

14. A method for constructing an espresso cartridge, the method comprising:
obtaining a fillable espresso cartridge, the espresso cartridge comprising:
a cartridge base comprising;
frustoconical shaped walls;
a cartridge base top sealed by foil; and
an open cartridge base bottom having a smaller diameter than the cartridge base top; and

a bottom plug configured to insert into the open cartridge base bottom, the bottom plug configured to release brewed beverage through the bottom plug during brewing; and

placing the frustoconical shaped brewing cartridge base onto a cartridge seat of a tool base, the sealed cartridge base top against the cartridge seat, the cartridge base top having a larger diameter than the open cartridge base bottom opposite the cartridge base top;
attaching a cartridge lock to the tool base to retain the cartridge base against the tool base;
using a scoop end of a scoop/tamper/seating tool to scoop a portion of brewing material;
using a sliding level engaged in a slot of the scoop/tamper/seating tool to level the brewing material to obtain a proper amount of brewing material for the espresso cartridge;
pouring the brewing material through a mouth of the cartridge lock and the open cartridge base bottom, into the cartridge base;
using a tamping end opposite to the scoop end of the scoop/tamper/seating tool to tamp the untamped brewing material into the cartridge base;
positioning a bottom plug above the open cartridge base bottom;
engaging a guide hole of the bottom plug with a guide hole pin on the tamping end of the scoop/tamper/seating tool;
inserting the tamping end of the scoop/tamper/seating tool into an access mouth of the cartridge lock;
seating the bottom plug into the open cartridge base bottom; and
removing the finished cartridge from the tool.
