Abstract
An elastic squeeze bottle which springs back to shape after collapse by squeezing, contains a viscous product and has a normally closed valve opened by the displaced product and which automatically closes again when the squeezing is terminated. So that air can enter the bottle to replace the displaced product, the valve has a permanently open package proportioned so that the air can be sucked into the bottle, but the passage being too small to permit the viscous product to gravitationally leak from the bottle through the passage.
