Hose end sprayer with multi-size bottle connectors and bottle adapter
A hose end sprayer has a sprayer lid and a container. The sprayer lid has a cap with a pair of bottle connectors formed of single-ended, fixed diameter, threaded sleeves of different radii mounted on the underside of the sprayer lid's cap. The connectors and a threaded adapter allow the sprayer lid to be connected with containers having mouths of different sizes, including containers in which liquid chemicals are sold. A liquid conduit extends across the cap between a hose inlet on one end and a spray nozzle on the other end, with a siphon tube intersecting the conduit within the periphery of the smaller of the bottle connectors, with mixture of pressurized carrier water entering the liquid conduit at the hose inlet with liquid chemical siphoned from the container through the siphon tube. The chemical/water admixture is expelled from the spray nozzle.
1. A hose end sprayer with multi-size bottle connectors comprising:
a lid including:
a cap having a top and two annular bottle connectors with different diameters positioned on an underside of the top;
a liquid conduit extending across the top, the conduit having an inlet at one end that is attachable to a hose and an outlet nozzle at an opposite end for discharging liquid; and
a siphon tube having an upper end connected to and in fluid communication with an interior of the conduit at a point inside of the periphery of the smaller bottle connector, the siphon tube extending downwardly from the upper end to a lower end positioned below the upper end, the siphon tube being formed such that liquid in communication with the lower end of the siphon tube is urged upwardly from the lower end through the upper end into the liquid conduit as a result of liquid flowing through the liquid conduit causing the admixture of liquid in the inlet conduit with liquid drawn through the siphon tube, with the admixed liquids being discharged from the outlet nozzle;
at least one adapter threaded at a first end to be attachable to one of the annular bottle connectors and threaded at a second end, opposed to the first end, having a diameter that is different from both of the two annular bottle connectors; and
at least one liquid container adapted to hold a liquid chemical, the liquid container having an open mouth of a size and shape that mates with and is releasably attachable to one of the annular bottle connectors or the adapter, such that when the container is attached to the lid, or when the container is attached to the adapter and the adapter is attached to the lid, and the container is filled with a sufficient quantity of liquid chemical that the liquid chemical is in communication with the lower end of the siphon tube, the liquid chemical is siphoned into liquid that is transmitted through the sprayer from the hose inlet to the nozzle, thereby causing admixed liquids to be discharged from the nozzle.
2. The hose end sprayer according to claim 1 , wherein the cap further comprises a mixing valve controlled by a movable dial incorporated in the cap that regulates the proportions of liquid chemical from the container and liquid from the hose that are discharged from the sprayer.
3. The hose end sprayer according to claim 1 , wherein the cap has a single top and the connectors are formed together unitarily with the top from synthetic resin.
4. A sprayer kit, the kit comprising:
a hose end sprayer lid with dual-size bottle connectors, wherein the sprayer lid comprises:
a cap having a top and two annular bottle connectors with different diameters positioned on an underside of the top; and
a liquid conduit extending across the top, the conduit having an inlet at one end that is attachable to a hose and an outlet nozzle at an opposite end for discharging liquid;
at least one adapter, wherein each adapter is threaded at a first end to be attachable to one of the annular bottle connectors and threaded at a second end, opposed to the first end, having a diameter that is different from both of the two annular bottle connectors;
two or more siphon tubes of differing lengths, wherein each of the siphon tubes has an upper end connectable to be in fluid communication with an interior of the conduit at a point inside of the periphery of the smaller bottle connector, each siphon tube extending downwardly from the upper end to a lower end positioned below the upper end, each siphon tube being formed such that liquid in communication with the lower end of the siphon tube is urged upwardly from the lower end through the upper end into the liquid conduit when connected to be in fluid communication with the conduit as a result of liquid flowing through the inlet into the liquid conduit; and
one or more liquid containers adapted to hold a liquid chemical, each liquid container having an open mouth of a size and shape that mates with and is releasably attachable to one of the annular bottle connectors or the adapter, such that when the container is attached to the lid or when the container is attached to the adapter and the adapter is attached to the lid, and when one of the siphon tubes is connected to be in fluid communication with the conduit, and the container is filled with a sufficient quantity of liquid chemical that the liquid chemical is in communication with the lower end of the siphon tube, the liquid chemical is siphoned into liquid flowing through the sprayer from the inlet of the conduit to the nozzle, causing admixed liquids to be discharged from the nozzle.
5. The sprayer kit of claim 4 , wherein at least one of the liquid containers comprises a retail packaging container in which a chemical is customarily distributed, and wherein one of the siphon tubes has a first length such that a lower end of that siphon tube is positioned so as to be in fluid communication with the interior of the retail packaging container at a point adjacent the bottom thereof when the retail packaging container is attached directly to one of the bottle connectors.
6. The sprayer kit of claim 4 , wherein at least one of the liquid containers comprises a retail packaging container in which a chemical is customarily distributed, and wherein one of the siphon tubes has a first length such that a lower end of that siphon tube is positioned so as to be in fluid communication with the interior of the retail packaging container at a point adjacent the bottom thereof when the retail packaging container is attached to one of the bottle connectors using the adapter.
7. The sprayer kit of claim 4 , wherein at least one of the liquid containers comprises a liquid chemical bottle of a type that is customarily used to package and sell the liquid chemical, and none of the bottle connectors is designed to fit on a mouth on the liquid chemical bottle, such that the lid is attachable, using the adapter, to the liquid chemical bottle without transfer of the liquid chemical to another container for use with the hose end sprayer.
