Abstract

A cover is provided for use in combination with a receptacle for coffee. The cover is utilizable in a receptacle having a circular, horizontal cross-section and rests on the top of the surface of the coffee in the receptacle. The cover comprises a circular disc having a radially extending slit which extends from the center of the disc to the periphery thereof to enable an overlapping of the portions of the disc on opposite sides of the slit but adjacent thereto. The disc has a larger diameter than the diameter of the bore of the bottle so that the periphery of the disc bears against the inner surface of the receptacle to protect the coffee from exposure to air.

Claims

1. In combination a receptacle having coffee in dry granular form therein, said receptacle having a circular-cross-section, and a cover for resting on the top surface of said coffee, said cover comprising a circular disc having a radially extending straight edge slit which extends from the center of said disc to the periphery thereof, said slit enabling an overlapping of the portions of said disc on opposite sides of said slit but adjacent thereto, said disc being of a larger diameter than the diameter of the bore of said recepticle, said disc being comprised of relatively flexible resilient material so that said disc (is conically shaped) assumes a conical shape whose apex points towards the coffee in said receptacle when said periphery of said disc bears against the inner surface of said receptacle to thereby protect said coffee from exposure to air, said flexibility of said disc and said straight edged slit together enabling the entry of a teaspoon in order to remove a level teaspoon of granulated coffee at a time from said receptacle without removing said cover.

2. The cover of claim 1 wherein said receptacle has a gradually varying cross-section along the height of the receptacle.
