Abstract
Medicament delivery device components that compensate for manufacturing tolerances are presented, where the medicament delivery device component can have a base portion extending in an axial direction relative to an axis, a compensation member having a first portion attached to the base portion and a second portion attached to the first portion and spaced apart from the base portion in the axial direction. The second portion can have a disc extending around the axis in the circumferential direction and a protrusion extending from the disc in the axial direction, wherein the protrusion is spaced apart from the first portion in the circumferential direction. At least part of the disc is configured to flex relative to the base portion when acted on by a force in the axial direction.
Claims18
A medicament delivery device component that compensates for manufacturing tolerances, the medicament delivery device component comprising:
- a base portion extending in an axial direction along the longitudinal axis of the medicament delivery device component;
- and
- a compensation member comprising, a first portion attached to the base portion;
- and
- a second portion attached to the first portion and spaced apart from the base portion in the axial direction, wherein the second portion comprises a disc extending around the longitudinal axis in a circumferential direction and a protrusion extending from the disc in the axial direction, where the protrusion is spaced apart from the first portion in the circumferential direction, and wherein the protrusion is V-shaped having a first straight portion and a second straight portion that converge at a vertex of the V-shaped protrusion, and wherein the first straight portion and the second straight portion diverge from one another radially away from the longitudinal axis, such that the vertex is radially closer to the longitudinal axis than the remainder of the V-shaped protrusion;
- and
- wherein at least part of the disc is configured to flex relative to the base portion when acted on by a force in the axial direction.
A medicament delivery device component for compensating for manufacturing tolerance, the medicament delivery device component comprising:
- a compensation member and a second compensation member attached to the compensation member, the medicament delivery device component extending in an axial direction along the longitudinal axis of the medicament delivery device component,
- the compensation member comprising a first portion and a second portion, the second compensation member comprising a first portion and a second portion,
- wherein the first portion of the compensation member and the first portion of the second compensation member are attached to each other,
- wherein the second portion of the compensation member is attached to the first portion of the compensation member and is spaced apart from the second compensation member in the axial direction when the medicament delivery device component is in an unbiased state, and wherein the second portion of the compensation member is configured to flex relative to the second compensation member when acted on by a force in the axial direction,
- wherein the second portion of the second compensation member is attached to the first portion of the second compensation member and is spaced apart from the compensation member in the axial direction when the medicament delivery device component is in an unbiased state, and wherein the second portion of the second compensation member is configured to flex relative to the compensation member when acted on by a force in the axial direction, and
- wherein the medicament delivery device component comprises a protrusion extending from the second portion of the compensation member and a protrusion extending from the second portion of the second compensation member, and wherein each of the protrusion extending from the second portion of the compensation member and the protrusion extending from the second portion of the second compensation member is V-shaped and having a first straight portion and a second straight portion that converge at a vertex of the V-shaped protrusion, and wherein the first straight portion and the second straight portion diverge from one another radially away from the longitudinal axis, such that the vertex is radially closer to the longitudinal axis than the remainder of the V-shaped protrusion.
A medicament delivery device component that compensates for manufacturing tolerances, the medicament delivery device component comprising:
- a base portion extending in an axial direction along the longitudinal axis of the medicament delivery device component, where the base portion is tubular;
- a compensation member comprising, a first portion attached to the base portion and a second portion attached to the first portion and spaced apart from the base portion in the axial direction, wherein the second portion comprises a disc extending around the longitudinal axis in a circumferential direction in a plane perpendicular to the longitudinal axis in a first unbiased state, wherein the disc comprises two protrusion that extend from a surface in the axial direction, where the protrusions are spaced apart from the first portion and from each other in the circumferential direction, and wherein each of the protrusions is V-shaped having a first straight portion and a second straight portion that converge at a vertex of the V-shaped protrusion, and wherein the first straight portion and the second straight portion diverge from one another radially away from the longitudinal axis, such that the vertex is radially closer to the longitudinal axis than the remainder of the V-shaped protrusion;
- and
- wherein the disc moves from the unbiased state to a flexed state relative to the base portion when acted on by a force in the axial direction.
