Abstract

A piercing device ( 150 ) contains a recessed piercing element ( 160 ) and is configured to receive a distal end ( 118 ) of an inhaler article ( 110 ). The piercing element pierces or punctures a single hole into a capsule contained within the inhaler article when the inhaler article is seated into an inhaler article cavity ( 157 ) of the piercing device. The piercing device includes a marking element ( 170 ) extending into the inhaler article cavity from the housing inner surface ( 152 ). The marking element is configured to mark an outer surface of an inhaler device when the inhaler device is received within the inhaler article cavity. The marking element extends orthogonally to the piercing element longitudinal axis.

First claim

The invention claimed is:

1. A piercing device comprising:
a housing, having a housing outer surface and a housing inner surface, the housing inner surface defining an inhaler article cavity, the housing extending along a housing longitudinal axis from a distal end to an open proximal end a housing length, the housing open proximal end is configured to receive the distal end of an inhaler article into the inhaler article cavity;
a piercing element fixed to and extending from the housing inner surface, into the inhaler article cavity along a piercing element longitudinal axis a piercing element length, the piercing element being recessed from the open proximal end a recessed distance; and
a marking element extending into the inhaler article cavity from the housing inner surface, the marking element extends orthogonally to the piercing element longitudinal axis, the marking element configured to mark the surface of an inhaler article when the inhaler article is received within the inhaler article cavity.

2. The piercing device according to claim 1 , wherein the marking element has a sharp end configured to scratch the outer surface of an inhaler article when the inhaler article is received within the inhaler article cavity.

3. The piercing device according to claim 1 , wherein the marking element is configured to apply a color to the outer surface of an inhaler article when the inhaler article is received within the inhaler article cavity.

4. The piercing device according to claim 1 , wherein the marking element is configured to mark the outer surface of an inhaler article when the piercing element penetrates a capsule disposed within the inhaler article.

5. The piercing device according to claim 1 , wherein the piercing element is recessed from the open proximal end a recessed distance of at least about 25% of the housing length.

6. The piercing device according to claim 1 , wherein the piercing element is formed from a metal.

7. The piercing device according to claim 1 , wherein the piercing element longitudinal axis is substantially coaxial with the housing longitudinal axis, and an inhaler longitudinal axis, when the inhaler article is received within the piercing device.

8. The piercing device according to claim 1 , wherein the piercing element length is about 25% to about 60% of the housing length.

9. The piercing device according to claim 1 , wherein the inhaler article cavity has a closed distal end and the piercing element extends through the closed distal end.

10. The piercing device according to claim 9 , further comprising a piercing element cavity defined at the distal end of the housing and the closed distal end defines a base of the piercing element cavity and the piercing element cavity receives the piercing element.

11. The piercing device according to claim 10 , further comprising a retaining element configured to retain the piercing element within the piercing element cavity.

12. The piercing device according to claim 11 , wherein the retaining element forms a portion of the distal end of the housing and the retaining element is removably coupled to the housing.

13. An inhaler system comprising:
an inhaler article comprising a body having an outer surface, the body extending along an inhaler longitudinal axis from a mouthpiece end to a distal end, a body length; and
the piercing device according to claim 1 , wherein the piercing device marking element marks the outer surface of the inhaler article when the inhaler article is received in the inhaler article cavity.

14. The inhaler system according to claim 13 , further comprising a capsule disposed within the inhaler article, the marking element is configured to mark the outer surface of the inhaler article when the piercing element penetrates the capsule.
