Holder for inhaler article
A holder ( 150 ) for an inhaler article ( 110 ) includes a housing ( 151 ) defining an inhaler article cavity ( 154 ). A piercing element ( 160 ) is fixed to and extends into the inhaler article cavity. A sleeve ( 180 ) is disposed within the inhaler article cavity and is configured to retain an inhaler article. The sleeve is movable along the housing longitudinal axis. A spring element ( 200 ) is configured to bias the sleeve toward the open proximal end ( 156 ) of the housing.
1 . An inhaler system comprising:
an inhaler article comprising a body having an outer surface, the body extending along an inhaler article longitudinal axis from a mouthpiece end to a distal end, a body length, and a capsule disposed within the body; and
a holder for the inhaler article, the holder 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 along a housing length, the open proximal end configured to receive the distal end of the inhaler article into the inhaler article cavity;
a piercing element is configured to penetrate the capsule, wherein the piercing element fixed to and extending from the housing inner surface, into the inhaler article cavity along a piercing element longitudinal axis extending along a piercing element length, the piercing element being recessed from the open proximal end a recessed distance;
a sleeve disposed within the inhaler article cavity and configured to retain the inhaler article, the sleeve being movable along the housing longitudinal axis; and
a spring element configured to bias the sleeve toward the open proximal end of the housing;
wherein the piercing element pierces the capsule when the inhaler article is received in the inhaler article cavity.
2 . The inhaler system according to claim 1 , wherein the sleeve extends from a sleeve open proximal end to a sleeve distal end and a base surface located at the sleeve distal end, and wherein the piercing element extends into the sleeve through the base surface.
3 . The inhaler system according to claim 2 , wherein the distal end of the inhaler article contacts the base surface of the sleeve.
4 . The inhaler system according to claim 1 , wherein inhalation air enters the open proximal end and then enters the distal end of the inhaler article.
5 . The inhaler system according to claim 3 , wherein inhalation air enters the open proximal end and then enters the distal end of the inhaler article.
6 . The inhaler system according to claim 1 , wherein the sleeve retains the inhaler article via interference fit.
7 . The inhaler system according to claim 1 , wherein the spring element is disposed within the inhaler article cavity between the sleeve and the distal end of the housing and contacts the sleeve and the distal end of the housing.
8 . The inhaler system according to claim 1 , wherein the spring element is disposed about the piercing element.
9 . The inhaler system according to claim 1 , wherein the spring element is a conical spring.
10 . The inhaler system according to claim 1 , wherein the piercing element extends beyond the spring element when the sleeve compresses the spring element.
11 . The inhaler system according to claim 1 , wherein the sleeve comprises an elongated slot extending along a longitudinal length of the sleeve and the housing further comprises an alignment pin extending from the housing inner surface into the inhaler article cavity, the pin being configured to mate with the elongated slot.
12 . The inhaler system according to claim 1 , wherein the sleeve defines a first air inlet zone comprising at least one air aperture through the sleeve, the first air inlet zone proximate to a proximal end of the sleeve, the first air inlet zone configured to allow air to flow from an inside of the sleeve to an airflow channel formed between the sleeve and the housing inner surface, and the sleeve comprises a second air inlet zone comprising at least one air aperture through the sleeve, the second air inlet zone proximate to a distal end of the sleeve, the second air inlet zone configured to allow air to flow from the airflow channel to the inside of the sleeve.
13 . The inhaler system according to claim 1 , wherein the sleeve defines an inner cavity and a portion of the inner cavity has a reduced internal diameter relative to remaining portions of the inner cavity.
14 . The inhaler system according to claim 12 , wherein the sleeve defines an inner cavity having a reduced inner diameter between the first air inlet zone and the second air inlet zone, and the first air inlet zone has a greater inner diameter than the reduced inner diameter between the first air inlet zone and the second air inlet zone.
15 . The inhaler system according to claim 1 , wherein the holder further comprises a retaining ring element fixed to the open proximal end of the housing, wherein the retaining ring element retains the sleeve within the inhaler article cavity.
16 . The inhaler system according to claim 1 , wherein the holder further comprises a marking element separate from the piercing element extending into the inhaler article cavity from the housing inner surface, the marking element configured to mark the outer surface of the inhaler article when the inhaler article is received within the inhaler article cavity.
17 . The inhaler system according to claim 16 , wherein the marking element is configured to scratch or apply a color to the outer surface of the inhaler article when the inhaler article is received within the inhaler article cavity.
18 . The inhaler system according to claim 16 , wherein the marking element is configured to mark the outer surface of the inhaler article when the piercing element penetrates the capsule disposed within the inhaler article.
