## Abstract

The method includes defining a cavity within a housing of a vapor-generating article, the vapor-generating article having a first end, a second end and a middle section, first inserting at least one portion of a retention medium within the housing between the first end and the middle section, and second inserting a first frangible capsule to be near or at least partially within the retention medium, the first frangible capsule including a first volatile substrate.

## Claims

### Claim 1

A method, comprising:
defining a cavity within a housing of a vapor-generating article, the vapor-generating article having a first end, a second end and a middle section;
first inserting at least one portion of a retention medium within the housing between the first end and the middle section; and
second inserting a first frangible capsule to be near or at least partially within the retention medium, the first frangible capsule including a first volatile substrate.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
first configuring the vapor-generating article to allow air to be drawn through the cavity from the first end to the second end if a negative pressure is applied to the second end.

### Claim 3 (depends on 2)

The method of claim 2, further comprising:
second configuring the vapor-generating article to be connected to an electrically-operated vapor-generating device.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
third inserting a second frangible capsule to be near or at least partially within the retention medium, the second frangible capsule including a second volatile substrate.

### Claim 5 (depends on 4)

The method of claim 4, wherein the second inserting inserts the first frangible capsule such that the first volatile substrate includes a first constituent of a pre-vapor formulation and the third inserting inserts the second frangible capsule such that the second volatile substrate includes a second constituent of the pre-vapor formulation.

### Claim 6 (depends on 4)

The method of claim 4, wherein the second inserting inserts the first frangible capsule such that the first volatile substrate includes a first constituent of a pre-vapor formulation and the third inserting inserts the second frangible capsule such that the second volatile substrate includes a second constituent of the pre-vapor formulation,
the pre-vapor formulation including between 10 weight percent and 25 weight percent water, an aerosol former, and at least one flavorant.

### Claim 7 (depends on 1)

The method of claim 1, wherein the second inserting inserts the first frangible capsule such that the first volatile substrate is releasably contained within the first frangible capsule, the retention medium being configured to retain the first volatile substrate once the first volatile substrate is released from the first frangible capsule.

### Claim 8 (depends on 4)

The method of claim 4, wherein the second inserting and the third inserting inserts that first frangible capsule and the second frangible capsule such that the first volatile substrate and the second volatile substrate are releasably contained within the first frangible capsule and the second frangible capsule, respectively,
the retention medium being configured to retain the first volatile substrate and the second volatile substrate once the first volatile substrate and the second volatile substrate are released from the first frangible capsule and the second frangible capsule, respectively.

### Claim 9 (depends on 4)

The method of claim 4, further comprising:
wrapping a plurality of elements using a wrapper, the housing including the wrapper, the retention medium being in a first element of the plurality of elements, the first element at least partially forming the first end.

### Claim 10 (depends on 9)

The method of claim 9, wherein the wrapping includes wrapping a second element of the plurality of elements using the wrapper, the second element including a cooler, the second element being downstream of the first element.

### Claim 13 (depends on 4)

The method of claim 4, wherein the first inserting inserts the retention medium so that a tube defined by the retention medium is in communication with the cavity.

### Claim 14 (depends on 13)

The method of claim 13, wherein the second inserting and the third inserting inserts the first frangible capsule and the second frangible capsule to be within the tube.

### Claim 15 (depends on 14)

### Claim 16 (depends on 1)

The method of claim 1, wherein the first inserting inserts the at least one portion of the retention medium so that an absorbent polymeric material is included in the retention medium within the housing.

### Claim 17 (depends on 1)

The method of claim 1, wherein the second inserting inserts the first frangible capsule such that
the first frangible capsule is configured to rupture by an application of an external force.

### Claim 18 (depends on 4)

The method of claim 4, wherein the second inserting and the third inserting inserts the first frangible capsule and the second frangible capsule such that the first frangible capsule and the second frangible capsule are each configured to rupture by an application of an external force.

### Claim 19 (depends on 1)

The method of claim 1, further comprising:
connecting a porous plug to the second end.

### Claim 20 (depends on 1)

The method of claim 1, further comprising:
providing the housing, the housing including a wrapper made at least in part by a non-porous material.

### Claim 21 (depends on 1)

The method of claim 1, further comprising:
connecting the vapor-generating article to an electrically-operated vapor-generating device, the electrically-operated vapor-generating device including a heating element that is configured to heat the first volatile substrate to form a vapor when the first volatile substrate is in the retention medium.
