A collapsible bottle is particularly useful as a beverage bottle such as a water bottle or soda bottle which can be collapsed after its contents are emptied in order to reduce its volume whereby the collapsed bottle takes up less space in trash receptacles, recycling bins and so forth. Grooves are formed in the bottle to facilitate its collapse and visual indicators on the bottle suggest to the user the need to collapse the bottle. These visual indicators may include arrows, fingertip indentations, outwardly projecting ridges or other structures. In one embodiment, annular groove walls define annular grooves in which interruption members are disposed to interrupt the continuity of the grooves. Break spaces may be provided which interrupt the continuity of the groove walls to facilitate collapse of the bottle.
