Abstract: A bottle and carrier assembly adapted to facilitate the recycling of polyester resin bottles is disclosed. The assembly comprises a reusable bottle carrier having a side wall and a bottom surface, and a recyclable polyester resin bottle. The bottle has an upper neck portion, an elongate body portion, and a rounded bottom portion which prevents the bottle from standing upright when placed on a level surface. The bottle is removably disposed within the bottle carrier in an upright configuration, with the side walls of the bottle carrier overlying a major part of the bottle elongate body portion. The side walls of the bottle carrier and the elongate body portion of the bottle have interengaging portions for maintaining the upright configuration of the bottle. The rounded bottom portion of the bottle serves to discourage the removal, by a consumer, of the recyclyable bottle from the reusuable bottle carrier.
