COFFEE TAMPER WITH STEP DESIGN

Abstract

A handheld coffee tamper having a circular tamper base, connected to a handle, wherein the cross section design of the circular tamper base has a stepped configuration where the base of the tamper and the first rise of the first step has a sharp edge having a radius of less than 0.2 mm, where the rise of the first step is between 0.5 to 4.0 mm and the run of the first step is between 0.05 to 2.0 mm and where the second step forms the side wall of the tamper, where the side wall is at least 5.0 mm in height, and where tamper base has a Rockwell hardness of at least 25.

Claims

1. A handheld coffee tamper having a circular tamper base, connected to a handle, characterised, in that the cross section design of the circular tamper base has a stepped configuration where the base of the tamper and the first rise of the first step has a sharp edge having a radius of less than 0.2 mm, where the rise of the first step is between 0.5 to 4.0 mm and the run of the first step is between 0.05 to 2.0 mm and where the second step forms the side wall of the tamper, where the side wall is at least 5.0 mm in height, and where tamper base has a Rockwell hardness of at least 25.

2. The coffee tamper of claim 1 where, the tamper base is made from a stainless steel.

3. The coffee tamper of claim 2, where the tamper base is made using 431 stainless steel and subjected to a hardening process to bring the Rockwell hardness of the stainless steel to at least 25.

4. The coffee tamper of claim 1, where the tamper base has a Rockwell hardness of at least 40.

5. The coffee tamper of claim 1, where the tamper base has a Rockwell hardness of at least 48.

6. The coffee tamper of claim 1, where the tamper base has a tolerance of no more than a 0.15 mm gap between the base and the coffee ground basket/filter.

7. The coffee tamper of claim 1, where the tamper base provides a tamped surface of no less than 99.6% relative to the surface area of the coffee grounds to be tamped in the coffee ground basket/filter.

8. The coffee tamper of claim 1, where the tamper base that comes into contact with the coffee grounds is Teflon coated.

9. The coffee tamper of claim 1, where the sharp edge has a radius of less than 0.1 mm.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0019] For a better understanding of the invention, further description will now be given, with reference to drawings in which:

[0020] FIG. 1 illustrates a cross sectional view of the tamper of the invention and FIG. 2 illustrates a perspective view of the tamper of the invention.

[0021] The figures show a tamper base having a sharp edge (5) with a step design having a first rise (3) and first run (2) and a side wall (1) and a means for attaching a handle (4). The tamper handle is not shown.
