BACKGROUND OF THE INVENTION




Technical Field




This invention relates to a portable sprayer device. More particularly, it relates to a portable sprayer device having a frame member for supporting and protecting a chemical concentrate container.




A portable dispenser device which can provide accurate dilutions of chemical concentrates as well as spray them is available as the J-FILL Portable™ device from Johnson Wax Professional in Sturtevant, Wisconsin. While this device does perform with a high degree of efficiency, it does not afford a support or protection for the chemical concentrate container. Neither does it provide a hose attachment for spraying.




When employing portable dispenser devices, there is likelihood that the container for the chemical concentrate can inadvertently strike another object such as shelving or a doorway. This could damage the container causing it to leak. It should also be recognized that after prolonged usage, the operator may become fatigued and the operator may want to place the container on a supporting surface such as a floor, but inadvertently do so in a forceful manner. This also could damage the container.




It is also desirable that the portable dispenser device have a hose attachment so as to be more versatile in its spraying capability.




Thus, it can be seen that there is a need for an improved portable dispenser device which affords protection for the container as well as increased spraying capability.




The objects of the invention therefore are:




a. Providing an improved portable sprayer device.




b. Providing a portable sprayer device, which affords protection for the liquid concentrate container.




c. Providing a portable sprayer device, which affords a versatile spraying capability.




d. Providing a portable sprayer device of the foregoing type, which has an apparatus producing a vacuum function and also contains an air gap.




e. Providing a portable sprayer device of the foregoing type, which has a spillproof bottle feature.




SUMMARY OF THE INVENTION




The foregoing objects are accomplished and the shortcomings of the prior art are overcome by the portable sprayer device of this invention which includes a frame member having top, side and bottom portions. The bottom portion is defined by a floor member and a side protective portion, the floor member and side protective portion are constructed and arranged to receive a container on the inside of the side protective portion.




A fluid control valve has a fluid inlet connected to the top portion of the frame member and an eductor is connected to a side portion, the eductor and fluid control valve being in fluid communication. A fluid intake line is in fluid communication with the eductor and a container cap member. A hose member is in fluid communication with the eductor.




In one aspect, the side protective portion is provided by a continuous, uninterrupted wall and the floor member is provided by a strap.




In one embodiment, a fluid container is positioned in the bottom portion and inside the protective portion and the container is supported by the floor member.




In another embodiment the container has a spill proof plug.




In a preferred embodiment, the container has a spill proof plug and the cap member includes a plunger portion for activating the spill proof plug.




In another preferred embodiment, the eductor is back flow tolerant.

OPERATION




A better understanding of the portable sprayer devise


10


will be had by a description of its operation.




Cap member


40


is threadably placed on plug


75


, which causes plunger member


60


to depress valve member


84


as shown in FIG.


10


. This moves the passages


85


in tubular portion


86


out of sealing contact with valve sleeve


87


and provides a flow path of the cleaning concentrate from pick up tube


109


, though passages


85


of tubular portion


92


, orifices


65


and


68


to tubular connection


44


and ultimately to tube


42


, as seen in FIG.


1


. At the same time a venting of the container


16


is afforded by an opening (not shown) in the base


97


of the plug


75


and a flow path extending around the valve member


84


and between valve member


84


and valve retainer


93


.




A source of pressurized water such as from a hose is connected to hose connector


28


. A chemical concentrate such as a cleaner, a sanitizer, a degreaser, insecticide, or any other chemical concentrate contained in the container


16


. Valve portion


27


of valve member


26


is placed in the “ON” position, which allows water to flow through the eductor


24


to siphon the chemical concentrate from container


16


into the water and mix therewith. The mixed solution is then sprayed through hose


50


and nozzle


53


.




An important feature of the portable sprayer device


10


is the frame member


12


with the protective bottom portion


14


. As this is a portable device and will be carried about while spraying, it is exposed to various objects such as walls, furniture, machines, doorways, etc. The frame member


12


with the bottom portion


14


and the side portions


18


and


19


protect the container


16


from undesired contact and possible breakage. Further, the bottom portion


14


protects the bottom of the container


16


from sudden impact, should the sprayer device be inadvertently dropped or placed on a surface in a forceful manner.




It will thus be seen that there is now provided a portable sprayer device wherein the container of chemical concentrate is protected from damage. The sprayer device has been illustrated without a guard for the eductor


24


. If desired one can be provided and supported on the support flange


22


. Also, while the bottom portion


14


has been shown to have a particular height, this can be varied with as small of height as possible for reduced weight purposes yet of sufficient height to provide protection for the container


16


. The plug described above may also be of a different type which is the subject of commonly assigned U.S. Pat. No. 5,862,948 issued Jan. 26, 1999 which teachings are fully incorporated herein by reference. All such and other modifications within the spirit of the invention are meant to be within its scope as defined by the appended claims.
