Abstract

This invention relates to a regular coffee set which is simple to use and portable. It comprises a dripper body of approximately conical shape having an opening on its bottom, a cylindrical case having an opening corresponding to the above opening and a coffee cup to be fitted for a lowermost periphery of the cylindrical case. There is formed a heat insulating space between the dripper body and the cylindrical case. The dripper body is provided at its nearly whole side with a plurality of grooves and the lowermost periphery of the cylindrical case is provided with a corrugated portion so as to be well-fitted for an uppermost periphery of the coffee cup. By inserting the dripper body into the cylindrical case, a dripping container is formed and placed upon the coffee cup.

Claims

1. A regular coffee set, comprising:

a coffee cup having an open top, said open top having an inside diameter and an outside diameter;

a dripping container including an outer case and a dripping body spaced from said outer case to define a heat insulation area therebetween;

said outer case being generally cylindrical and having an open top and a first opening centrally disposed in its bottom;

said dripping body being fittable inside said outer case and having a generally conical cross sectional shape, an open top and a second opening centrally disposed in its bottom, said second opening being aligned with said first opening;

a plurality of grooves on said dripping body effective for expediting filtering a coffee through a filter placed within said dripping body;

an outside diameter of a bottom of said outer case being supportably fittable into said inside diameter of said open top of said coffee cup;

means on said outside diameter of said bottom of said outer case effective to impart resiliency to said outer diameter for easy fitting into said inside diameter of said open top of said coffee cup;

an inside of a top of said dripping container having a diameter for fitting top to top over said outside diameter of said coffee cup to function as a cap and to form a volume therein for containing supplies.
