Protective case for an auto-injector
First Claim
1. A protective case for enclosing a compact auto-injector used for delivering a medicament dose, the protective case comprising:
- a lower portion comprising;
a double wall forming a void therebetween that forms a sealed lower vacuum chamber; and
a lower sidewall flange, wherein the lower vacuum chamber extends within at least a portion of the lower sidewall flange; and
a mating upper portion comprising;
a double wall forming a void therebetween that forms a sealed upper vacuum chamber; and
an upper sidewall flange, wherein the upper vacuum chamber extends within at least a portion of the upper sidewall flange;
such that when the lower portion and the upper portion are mated, the lower and upper sidewall flanges overlap to form a substantially sealed thermally isolated interior cavity for receiving the auto-injector.

Abstract
The application describes a protective case for an auto-injector. The medicament contained within these auto-injectors can be susceptible to degradation due to exposure to extreme temperatures and light. Thus, one embodiment of the protective case reduces the rate of heat transfer between the internal storage compartment of the case and the external atmosphere by including particularly configured vacuum chambers. Additionally, as auto-injectors become smaller, portability can be desirable. Thus, another embodiment of the protective case includes low-profile cases that allow the user to keep the auto-injector with them, e.g., by attaching the case to a common everyday item.

24. A method of thermally isolating a compact auto-injector containing a medicament dose from ambient environmental temperatures, the method comprising the steps of:
-
providing a protective case comprising; a lower portion comprising; a double wall forming a void therebetween that forms a sealed lower vacuum chamber; and a lower sidewall flange, wherein the lower vacuum chamber extends within at least a portion of the lower sidewall flange; and a mating upper portion comprising; a double wall forming a void therebetween that forms a sealed upper vacuum chamber; and an upper sidewall flange, wherein the upper vacuum chamber extends within at least a portion of the upper sidewall flange; placing the auto-injector into an interior cavity portion formed by at least one of the lower portion and the upper portion; and mating the lower and upper sidewall flanges in overlapping relation to form a substantially sealed thermally isolated interior cavity for the auto-injector. - View Dependent Claims (25, 26, 27, 28, 29, 30)
