Bottle

A bottle comprising:

• a body having an internal chamber and an opening, the opening being at a first end of the bottle;
• and
• a closure movable relative to the body between a closed position at which the closure prevents the chamber from being in fluid communication with an exterior of the bottle, and an open position at which the chamber is in fluid communication with the exterior of the bottle via the opening;
• wherein the first end of the bottle comprises first and second elements and a recessed portion extending from the first element to the second element;
• wherein each of the first and second elements is a line or a planar surface in a plane substantially perpendicular to a main axis extending between the first end of the bottle and an opposite second end of the bottle, the first and second elements being respective portions of the first end of the bottle that are furthest along the main axis from the second end of the bottle;
• wherein the recessed portion is recessed from the plane in a direction along the main axis towards the second end of the bottle, whereby the first and second elements are separated from each other in the plane by a gap, the first and second elements together occupying a first area in the plane;
• wherein the recessed portion projects, in a direction parallel to the main axis, a second area onto the plane;
• and
• wherein the first area is between 1% and 25% of the sum of the first and second areas.
