## Abstract

An aerosol-generating system may comprise a releasably connectable capsule and vaporizing unit. The capsule may comprise a reservoir for containing an aerosol-generating substrate, an opening in fluidic communication with the reservoir, and a valve configured to control a flow of the aerosol-generating substrate from the reservoir through the opening. The valve may comprise one or more resilient closing members biased towards a closed position. The vaporizing unit may comprise a transfer element and a heating element disposed in a housing. The heating element is configured to heat the aerosol-generating substrate in the transfer element. The vaporizing unit may also comprise an elongate element configured to engage with the valve to deflect the one or more resilient closing members from the closed position to an open position so as place the transfer element in fluidic connection with the reservoir when the capsule is connected to the vaporizing unit.

## Claims

### Claim 1

A capsule of an aerosol-generating system, comprising:
a first housing defining a reservoir and an opening in fluidic communication with the reservoir, the reservoir configured to contain an aerosol-generating substrate; and
a valve engaged with the opening in the first housing, the valve configured to control a flow of the aerosol-generating substrate from the reservoir through the opening, the valve including one or more resilient closing members biased towards a closed position, the one or more resilient closing members configured to be deflected from the closed position to an open position.

### Claim 2 (depends on 1)

The capsule according to claim 1, wherein the valve includes a first resilient closing member and a second resilient closing member, and the first and second resilient closing members are configured to contact each other when in the closed position.

### Claim 3 (depends on 2)

The capsule according to claim 2, wherein the first resilient member includes a first flat portion and the second resilient member includes a second flat portion, and the first and second flat portions are configured to contact each other when in the closed position.

### Claim 4 (depends on 3)

The capsule according to claim 3, wherein the valve is in a form of a duckbill valve.

### Claim 5 (depends on 1)

The capsule according to claim 1, wherein the first housing defines a port as the opening, and the valve is seated in the port.

### Claim 6 (depends on 5)

The capsule according to claim 5, further comprising:
a sealing element disposed across a distal side of the port.

### Claim 7 (depends on 1)

The capsule according to claim 1, wherein the reservoir is configured to be filled entirely with a free-flowing liquid as the aerosol-generating substrate.

### Claim 8 (depends on 7)

The capsule according to claim 7, further comprising:
the free-flowing liquid disposed in the reservoir.

### Claim 9

A vaporizing unit of an aerosol-generating system, comprising:
a housing including a proximal side, an opposing distal side, and an elongate element extending from the proximal side;
a transfer element including a first portion and a second portion, the first portion disposed in the housing, the transfer element configured to transport an aerosol-generating substrate into the housing; and
a heating element disposed in the housing and configured to heat the transfer element to vaporize the aerosol-generating substrate.

### Claim 10 (depends on 9)

The vaporizing unit according to claim 9, wherein the second portion of the transfer element extends beyond the proximal side of the housing and is configured to extend into a valve of a capsule so as to connect the vaporizing unit and the capsule.

### Claim 11 (depends on 10)

The vaporizing unit according to claim 10, wherein the elongate element of the housing includes a sheath disposed about the second portion of the transfer element.

### Claim 12 (depends on 1)

An aerosol-generating system comprising:
the capsule according to claim 1; and
a vaporizing unit configured to be releasably connected to the capsule, the vaporizing unit including a second housing, a transfer element, and a heating element, the second housing including a proximal side, an opposing distal side, and an elongate element extending from the proximal side, the transfer element including a first portion and a second portion, the first portion disposed in the second housing, the transfer element configured to transport an aerosol-generating substrate into the second housing, the heating element disposed in the second housing and configured to heat the transfer element to vaporize the aerosol-generating substrate, the elongate element of the second housing of the vaporizing unit configured to be received in the valve of the capsule to deflect the one or more resilient closing members from the closed position to the open position such that the transfer element is placed in fluidic communication with the reservoir when the capsule is connected to the vaporizing unit.

### Claim 13 (depends on 12)

The system according to claim 12, wherein the first housing defines a port as the opening, the valve being seated in the port, the capsule further comprising a sealing element disposed across a distal side of the port, the elongate element of the vaporizing unit configured to pierce the sealing element when the capsule is connected to the vaporizing unit.

### Claim 14 (depends on 12)

The system according to claim 12, further comprising:
a cover configured to be disposed over the capsule and the vaporizing unit.
