Claim:
A hose-end sprayer apparatus for attachment to a hose, said apparatus comprising: a sprayer which selectably admits throughput of a carrier stream from a hose; a container interface for interfacing with a container which contains product for mixing with a carrier stream; an adjuster which establishes a delivery condition of a carrier stream and product; said adjuster being actuable between: a first setting, wherein no carrier stream is admitted through said sprayer; a second setting, wherein solely a carrier stream is admitted through said sprayer; a third setting, wherein product is admitted into a carrier stream admitted through said sprayer; and a safety arrangement which acts to ensure a more hindered transition of said adjuster from said first setting towards said third setting than from said third setting towards said first setting; wherein said second setting is intermediate to said first and third settings; said safety arrangement comprises: a tab comprising a portion disposed at said sprayer; a first engagement portion, disposed on said adjuster, which is engageable with said tab as said adjuster transitions from said first setting to said second setting; a second engagement portion, disposed on said adjuster, which is engageable with said tab as said adjuster transitions from said second setting to said first setting; and a support tab, said support tab acting to arrest movement of said tab; said first engagement portion and said second engagement portion being comparatively shaped to ensure a more hindered transition of said adjuster from said first setting to said second setting than from said second setting to said first setting.
