What changed

This document is a publication of a patent application (US20260083916A1) filed with the USPTO on December 1, 2025. The application describes an assembly for a drug delivery device, specifically focusing on a cap mechanism that utilizes a rotatable member and an internal track to convert rotational user input into axial movement for releasing the cap from a housing. The abstract details how different regions of the track guide this movement, allowing for controlled displacement.

As this is a patent application, it does not impose immediate regulatory requirements or compliance deadlines on entities. However, it represents a new development in drug delivery device technology. Companies involved in the manufacturing or development of drug delivery devices, particularly those utilizing novel cap or release mechanisms, should be aware of this filing for potential intellectual property considerations and competitive landscape analysis.

ASSEMBLY FOR A DRUG DELIVERY DEVICE AND DRUG DELIVERY DEVICE

Application US20260083916A1 Kind: A1 Mar 26, 2026

Inventors

Uwe Dasbach, Thomas Mark Kemp, Timothy Denyer

Abstract

An assembly for a drug delivery device is provided, the assembly comprising: a housing for receiving a reservoir, and a cap releasable with respect to the housing, wherein the assembly has a capped state and an uncapped state, wherein the cap comprises a member to be gripped by a user for releasing the cap from the housing, wherein the member is rotatable to release the cap from the housing, wherein the assembly comprises an interface to convert rotational movement of the member into axial movement of the member, the interface comprising a track configured to guide movement of the member, wherein the track has a first region and a second region, wherein, when the first region guides the movement, the member is displaced from the housing by a first distance, and when the second region guides the movement, the member is displaced from the housing by a second distance.
