Abstract

A cartridge for a non-burning type flavor inhaler including a flow path forming body having a shape extending along a predetermined direction to form an aerosol flow path, an outer frame having a shape extending along the predetermined direction to accommodate the flow path forming body, a reservoir that is configured to retain an aerosol source, is positioned on the periphery of the flow path forming body in a cross section orthogonal to the predetermined direction and is positioned in a gap between the flow path forming body and the outer frame and an end cap that closes the gap from the downstream side, wherein an outer edge of the end cap contacts an inner wall surface of the outer frame in the cross section orthogonal to the predetermined direction and wherein an inner edge of the end cap is positioned between the outer edge of the flow path forming body and the inner edge of the flow path forming body in the cross section orthogonal to the predetermined direction.

Claims (14)

1. A cartridge for a non-burning type flavor inhaler comprising:

a flow path forming body having a shape extending along a predetermined direction to form an aerosol flow path;

an outer frame having a shape extending along the predetermined direction to accommodate the flow path forming body;

a reservoir that is configured to retain an aerosol source, is positioned on the periphery of the flow path forming body in a cross section orthogonal to the predetermined direction and is positioned in a gap between the flow path forming body and the outer frame; and

an end cap that closes the gap from a downstream side,

wherein an outer edge of the end cap contacts an inner wall surface of the outer frame in the cross section orthogonal to the predetermined direction; and

wherein an inner edge of the end cap is positioned between the outer edge of the flow path forming body and the inner edge of the flow path forming body in the cross section orthogonal to the predetermined direction.

2. The cartridge for a non-burning type flavor inhaler according to claim 1 , wherein the end cap comprises a protruding portion that protrudes from the outer edge of the end cap.

3. The cartridge for a non-burning type flavor inhaler according to claim 1 , wherein the end cap comprises a protruding portion that protrudes from the outer edge of the end cap to the upstream.

4. The cartridge for a non-burning type flavor inhaler according to claim 1 , wherein the outer frame comprises a space capable of accommodating a part of another cartridge downstream of the end cap, and

wherein an aerosol flow adjustment chamber that adjusts the flow of the aerosol supplied from the flow path of the flow path forming body to the other cartridge is formed in a part of the space between the end cap and the other cartridge in a state in which the other cartridge is inserted in the outer frame.

5. The cartridge for a non-burning type flavor inhaler according to claim 4 , wherein the other cartridge includes a flavor source.

6. The cartridge for a non-burning type flavor inhaler according to claim 1 , wherein the outer frame comprises a space capable of accommodating a part of another cartridge downstream of the end cap.

7. The cartridge for a non-burning type flavor inhaler according to claim 6 , wherein the other cartridge includes a flavor source.
