To enable simplified construction for a squeeze to use container 10 of the kind having an indication of the pressure zones 20 where the container walls 13 are to be squeezed to expel a controlled volume 25 of the contents 24 through a restricted opening 17, the invention provides that the controlled volume is determined by both the size of the restricted opening and the rigidity of the container walls. In one preferred form, a tactile indication 22 (Fig. 1) of the pressure zones is provided in recesses 21 in positions of walls made of plastics, where rigidity of the walls is greater than their overall minimum, so that under normal hand pressure, the walls are deformed partially but not sufficiently for them to touch internally. <IMAGE> |
