Abstract

A housing blank and an activation member blank for a medicament delivery device are disclosed, with a kit including a housing blank and an activation member blank, and a medicament delivery device assembled from the kit. The housing blank includes a mid portion having a through-opening for receiving a proximal end portion of a medicament container assembly, and first and second legs foldable relative to the proximal end portion. The activation member blank includes a central portion and a first and second arm foldable relative to the proximal end portion.

First claim

1 .- 16 . (canceled)

17 . A housing blank for a medicament delivery device, comprising:
a mid portion having a through-opening configured to receive a proximal end portion of a medicament container assembly; a first leg defining a first housing side wall and extending from a first end of the mid portion; and a second leg defining a second housing side wall and extending from a second end, opposite the first end, of the mid portion; wherein the housing blank has a first fold line that separates the first leg from the mid portion, the first fold line enabling folding of the first leg relative to the mid portion; and the housing blank has a second fold line that separates the second leg from the mid portion, the second fold line enabling folding of the second leg relative to the mid portion.

18 . The housing blank of claim 17 , wherein the first fold line enables folding of the first leg toward the second leg, and the second fold line enables folding of the second leg toward the first leg.

19 . The housing blank of claim 17 , wherein the first fold line defines a first pivot axis about which the first leg is pivotable in a first direction, and the second fold line defines a second pivot axis about which the second leg is pivotable in a second direction opposite the first direction.

20 . The housing blank of claim 17 , wherein the first fold line and the second fold line are parallel.

21 . The housing blank of claim 17 , wherein the first leg has a first leg end wall portion having a first through-opening, the second leg has a second leg end wall portion having a second through-opening, and the first and second leg end wall portions are arranged at different respective distances from the mid portion such that the first and second leg end wall portions form a housing end wall when the first and second legs are folded toward each other and the first and second through-openings align.

22 . The housing blank of claim 21 , wherein the first leg end wall portion is arranged at a distal end portion of the first leg relative to the mid portion, and the second leg wall portion is arranged at a distal end portion of the second leg relative to the mid portion.

23 . The housing blank of claim 21 , wherein the first and second leg end wall portions are perpendicular relative to the first leg and second leg, respectively.

24 . The housing blank of claim 21 , wherein the first and second leg end wall portions each have cut-outs in their corners.

25 . The housing blank of claim 17 , wherein each of the first and second legs has guides arranged to interact with respective guide followers of an activation member.

26 . An activation member blank for a medicament delivery device having a housing blank as claimed in claim 17 , the activation member blank comprising:
a central portion having a plunger rod; a first arm defining a first activation member side wall and extending from a first end of the central portion; and a second arm defining a second activation member side wall and extending from a second end, opposite the first end, of the central portion; wherein the activation member blank has a first fold line that separates the first arm from the central portion, the first fold line enabling folding of the first arm relative to the central portion; and the activation member blank has a second fold line that separates the second arm from the central portion, the second fold line enabling folding of the second arm relative to the central portion.

27 . The activation member blank of claim 26 , wherein the first fold line enables folding of the first arm toward the second arm, and the second fold line enables folding of the second arm toward the first arm.

28 . The activation member blank of claim 26 , wherein the first fold line defines a first pivot axis about which the first arm is pivotable in a first direction, and the second fold line defines a second pivot axis about which the second arm is pivotable in a second direction opposite the first direction.

29 . The activation member blank of claim 26 , wherein the first arm has a first guide follower for interacting with a first guide of a housing and arranged at a distal end of the first arm relative to the central portion, and wherein the second arm has a second guide follower for interacting with a second guide of the housing and arranged at a distal end of the second arm relative to the central portion.

30 . The activation member blank of claim 29 , wherein the first and second arms each have respective first and second edges, the first edge of the first arm being aligned with the first edge of the second arm and the second edge of the first arm being aligned with the second edge of the second arm; the first guide follower is arranged at the first edge of the first arm; and the second guide follower is arranged at the second edge of the second arm.

31 . A medicament delivery device kit, comprising a housing blank as recited in claims 17 , and an activation member blank as recited in claim 26 .

32 . A medicament delivery device for receiving a medicament container, assembled from a housing blank as recited in claim 17 and an activation member blank as recited in claim 26 .
