Abstract

A dispensing capsule includes a cylindrical cap body surrounding a cylindrical ingredient chamber. The chamber is disposed inside and extends through the cap body and is sealed at the bottom by a lower sealing member. A flexible actuator is attached to the top of the cap body. A moveable plunger is disposed in the chamber and is attached underneath and extends downwardly from the flexible actuator. Upon application of pressure to the flexible actuator, the plunger displaces downward and at least partially breaks the lower sealing member.

Claims

1. A dispensing capsule, comprising:

a cylindrical cap body surrounding a cylindrical ingredient chamber, said chamber disposed inside and extending through said cap body and sealed by a lower sealing member;

a flexible actuator comprising a stepped flexible element integrally attached to said cap body;

a vertically moveable plunger disposed in said chamber and integrally attached to and extending downwardly from underneath said flexible actuator;

said plunger having a triangular cutaway along its entire length so as to form an incomplete cone having one or more window vents to facilitate flow of liquid into and out of said chamber;

wherein upon application of pressure to said flexible actuator, said plunger displaces downward and at least partially breaks said lower sealing member; and

wherein said cap body, flexible actuator, and plunger are integrally constructed as a single piece.
