## Abstract

An apparatus for providing a thermal treatment to a product, such as food, is described. One embodiment of the apparatus includes lime and water contained separately within a sealed reaction vessel. The reaction vessel includes a flexible wall portion that is adjacent to a perforator that can puncture a membrane separating the lime and water. In one embodiment, the perforator is separate from and fee-floating within the water. In another embodiment, the reaction vessel is substantially surrounded by the product. The reaction vessel is hermetically sealed against underpressure or overpressure, permitting use with pressurized food. The reaction vessel can be incorporated into a variety of containers and the reaction vessel and container can be sterilized for packaging food.

## Claims

### Claim 1

A reaction vessel to facilitate the mixing and reaction of a first component and a second component, where said reaction vessel is in thermal contact with a product, where the product substantially surrounds said reaction vessel, and where said reaction vessel comprises:
a first compartment to contain the first component;
a second compartment to contain the second component, where said second compartment includes a flexible wall portion and a cylindrical wall having an axis of rotation;
a membrane perpendicular to said axis and positioned between said first compartment and said second compartment, where said membrane, when intact, prevents fluid communication between said first compartment and said second compartment, and where said membrane, when pierced, allows fluid communication between said first compartment and said second compartment; and
an actuator not affixed to said first compartment, said second compartment, or said membrane, where said actuator includes a base adjacent to said flexible wall portion, piercing elements that extend from said base in a direction towards said membrane, and a guide member that extends from said base in a direction towards said membrane forming an outer curved surface adjacent to said cylindrical wall and with the same curvature as said cylindrical wall,
where when said flexible wall portion is flexed, said flexible wall portion contacts said base and forces each of said piercing elements to move in a direction perpendicular to said membrane.

### Claim 2 (depends on 1)

The reaction vessel of claim 1, where said reaction vessel is configured to contain the first component, the second component, and any products of reaction of the first component and the second component.

### Claim 3 (depends on 1)

The reaction vessel of claim 1, where said base include holes, such that fluid may flow through said base.

### Claim 4 (depends on 1)

The reaction vessel of claim 1, where said outer curved surface has a length that is greater than one half of the length of said piercing members.

### Claim 5 (depends on 1)

The reaction vessel of claim 1, where said membrane has a shape perpendicular to said axis that is a circle having a center and an outer edge, and where said piercing members pierce said membrane at one or more locations between the center and the outer edge.

### Claim 6 (depends on 1)

The reaction vessel of claim 1, where said actuator is within said second compartment.
