Bottle warmer for disposable baby bottle
First Claim
1. A bottle warmer for warming a beverage stored in a disposable baby bottle assembly, the disposable baby bottle assembly including a hollow sleeve having a substantially cylindrical outer wall including a lower edge defining a lower opening, and a liner positioned inside the sleeve, the bottle warmer comprising:
- a housing including an opening for receiving the lower edge of the sleeve;
a heat transfer element mounted in the opening such that when the sleeve is inserted into the opening of the housing, the heat transfer element extends through the open bottom of the sleeve and contacts the liner, and a heat generator mounted in the housing and being coupled to the heat transfer element such that heat generated by the heat generator is transmitted to the heat transfer element.

Abstract
A bottle warmer for warming a beverage (e.g., baby formula or milk) stored in a disposable baby bottle assembly including a disposable liner supported in a hollow sleeve (holder). The bottle warmer includes a heat transfer element that enters a lower opening of the bottle sleeve and contacts the liner. In one embodiment, the heat transfer element includes a cylindrical wall that slides between the sleeve wall and the liner to facilitate faster heating. The bottle warmer also includes a portable (e.g., gas or electric) heat generating system that heats the heat transfer element, which in turn heats a beverage stored in the liner.
