Abstract
Abstract In a squeeze bottle including a container having an upstanding neck portion and a spray unit in the neck portion through which product is dispensed from the container, the improvement comprising bellowed portions in the walls of the container and a compressible shroud surrounding the container walls. The shroud is formed of two sections, which are joined by a mating groove and bead arrangement on their edges and which substantially overlap each other when a squeezing pressure is applied to the shroud and a predetermined resistance of the groove and bead arrangement is overcome, so that the shroud sections compress the bellowed container walls and product is dispensed.
