Safety features in and for hose-end sprayer bottles. In a first safety arrangement, there is ensured a more hindered transition of a spool (e.g., product/carrier spool) or adjuster from a first setting to a second setting than from the second setting to the first setting, wherein in the first setting no carrier stream is admitted through the sprayer and in the second setting solely a carrier stream is admitted through the sprayer. In a second safety arrangement, there is arrested displacement of a container interface (e.g., bottle swivel) from a second (essentially advanced) position towards a first (essentially initial) position upon the container interface displacing from the first position to the second position.
