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 comprising: a handle; and a circular tamper base connected to the handle, a cross section of the circular tamper base having a first step and a second step, wherein the first step comprises a first rise extending from a bottom of the circular tamper base and a horizontally first run formed on a top portion of the first rise and the second step comprises a second rise extending from the first run to form a sidewall of the circular tamper base, wherein the first rise of the first step having a sharp edge having a radius of less than 0.2 mm, a height of the first rise of the first step is between 0.5 to 4.0 mm and a length of the run of the first step is between 0.05 to 2.0 mm, and wherein the sidewall of the second step is at least 5.0 mm in height, and the circular tamper base has a Rockwell hardness of at least 25.

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

3. The coffee tamper of claim 2, wherein the tamper base is 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, wherein the tamper base has a Rockwell hardness of at least 40.

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

6. The coffee tamper of claim 1, wherein a surface of the circular tamper base that comes into contact with coffee grounds is Teflon coated.

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