## Abstract

A two-compartment container in which the first compartment has an upper layer and a lower layer and contains a first component that is to be added to the second compartment. There are at least two lacquer layers on the lower layer of the first compartment outside of the first compartment, between the second component and the first compartment. Above the first compartment is a dome that is bowed upward and is flexible. Depressing the dome by pushing downward on it causes the lower layer of the first compartment to be ruptured without cutting or rupturing the upper layer, releasing the first component into the second compartment.

## Claims

### Claim 1

A two-compartment container, for addition of a first component to a second component, comprising:
(a) a first compartment containing a first component, said first compartment having an upper layer and a lower layer, said lower layer of the first compartment being made of a rupturable material;
(b) a second compartment containing the second component, said second compartment having a cap containing a flexible dome; and
(c) at least two lacquer layers coating the lower layer between the second component in the second compartment and the lower layer;
wherein depression of said flexible dome causes the lower layer and the at least two lacquer layers to be ruptured but not the upper layer, releasing the first component into the second compartment without opening either compartment outside the container.

### Claim 2 (depends on 1)

The container according to claim 1, wherein the upper layer is thicker than the lower layer.

### Claim 3 (depends on 1)

The container according to claim 1, wherein there are 2-5 lacquer layers.
