Lawn and tree fertilizing device installable on a sprinkler system

摘要

A lawn fertilizing device for installing in a water system. A chemical substrate that is to be applied to vegetation is disposed in an enclosed container. The enclosed container has a plurality of apertures disposed on the container walls to allow water to flow through the container and contact the chemical substrate. The container is placed on a base and covered by a housing. The housing is secured to the base via a screw cap threaded to a base wall.

1. A lawn fertilizing device (100) for installing in a water system, said lawn fertilizing device comprising:
a. a tubular housing (110) having a top surface (112) and a side wall (113) forming an inner chamber (111), wherein a lower end rim (115) is disposed on a lower end (114) of the housing (110); b. a screw cap (130) with a top opening (132) and a lower opening (134), wherein an inner thread (136) is disposed within the screw cap, wherein the tubular housing (110) slidably passes through the lower opening (134) and out of the top opening (132) such that the screw cap (130) stops at the lower end rim (115); c. a base (210) having a base platform (211), a threaded base wall (212), a base first side (213) and an opposing base second side (214), wherein the threaded base wall (212) is disposed on a base top side (216) of the base platform (211) to form a base inner cavity (215), wherein the threaded base wall (212) is configured to engage the inner thread (136) of the screw cap (130) such that the tubular housing (110) is removably and water-tightly attached to the base (210), wherein the base inner cavity (215) is fluidly connected to the inner chamber (111) of the tubular housing (110) when the tubular housing (110) is attached to the base (210),  wherein an inlet pipe (250) is disposed on the base first side (213) and an outlet pipe (260) is disposed on the base second side (214) opposite of the inlet pipe (250), wherein the inlet pipe (250) and outlet pipe (260) are disposed below the base top side (216), wherein the inlet pipe (250) is fluidly connected to the base inner cavity (215) via a first base inner channel (252) having a base outlet end (254) disposed on the base top side (216), wherein the outlet pipe (260) is fluidly connected to the base inner cavity (215) via a second base inner channel (262) having a base inlet end (265) disposed on the base top side (216); d. an enclosed container (300) having an inner space (320) formed by container walls (310) and a plurality of apertures (330) disposed through at least a portion of the container walls (310), wherein the container (300) is disposed on the base top side (216) in between the base outlet end (254) and the base inlet end (265), wherein the container (300) is disposed within the base inner cavity (215) and inner chamber (111) of the tubular housing (110) when the tubular housing (110) is attached to the base (210); and e. a chemical substrate (400) disposed within the inner space (320) of the container (300), wherein the plurality of apertures (330) allows water to enter the container (300) and contact the chemical substrate (400);  wherein the water enters the inlet pipe (250), flows through the first base inner channel (252) and upwards to exit through the base outlet end (254) and enter the base inner cavity (215), wherein the water enters the container (300) and mixes with the chemical substrate (400) to form a chemical mixture, wherein the chemical mixture subsequently enters the base inlet end (265), flows through the second base inner channel (262) and downwards to exit the base (210) from the outlet pipe (260).
