Filed Aug. 15, 1962, Ser. No. 217,153 4 Claims. (Cl. 137--268) This invention relates to dispensing receptacles, and more particularly to a dispensing package of fluid soluble material, such as fertilizer, certain insecticides, and other like chemicals.
An object of the invention is to provide a package of the above-mentioned character which may be cheaply manufactured for'distribution to the wholesale or retail customerin a completely sealed condition, so that no moisture or other foreign matter can enter the package prior to use of the same.
Another object of the invention is to provide a dispensing package for fluid soluble fertilizers, insecticides and the like, formed entirely of heat scalable tough flexible plastic material capable of withstanding city water main pressure during use.
' Still another object of the invention is to provide a dispensing package or receptacle of the above-mentioned character which may be utilized in conjunction with an ordinary garden hose and conventional feed or proportioning device to dispense the packaged material onto a lawn, and around shrubbery and the like.
Another object is. to provide a package of the mentioned character having built-in sealed fluid inlet and outlet tubes, which needonly to be severed by the user, exteriorly of the package, in order that such tubes may be connected to a standard type feed and proportioning device.
f Another object is to provide a dispensing package for fluid .soluble materials, which is reliable and efficient in operation, highly simplified and economical in design, and cheap enough to be expendable after a single usage thereof.
Other objects and advantages of the invention will become apparent during the course of the following de tailed description.
In the accompanying drawings, forming a part of this application and in which like numerals are employed to designate like parts throughout the same,
' FIGURE 1 is a perspective view illustrating one manner of using the dispensing pack-age according to the invention,
FIGURE 2 is a perspective view on an enlarged scale showing the sealed package prior to use,
' FIGURE 3 is a further enlarged central vertical section, partly in elevation, through the package while the same is in use, and
FIGURE 4 is a plan view of the package.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 10 designates generally a receptacle or package body portion formed of tough water-impermeable flexible sheet plastic material, such as polyethylene, polystyrene, or the like. Most conveniently, the receptacle body portion 10 may be formed from a pair of precut rectangular sheets of said plastic materials, arranged in superposed relation and heat sealed together around their entire marginal edges, as indicated at 11. Thus formed, the package or receptacle body portion constitutes a substantially completed closed flexible envelope of any preferred size, adapted to be filled to the desired extent with fluid or water soluble fertilizer, insecticide, or the like, preferably in small particle form. The package body portion thus formed from the mentioned materials will be capable of withstanding ordinary city or household water pressure without bursting or parting.
The dispensing package further comprises a relatively long fluid inlet tube 12'and arelatively short outlet tube 13 through which water havingthe material within the package dissolved therein is conveyed to a garden hose or the like. The tubes 12 and 13 may be formed of the same plastic material utilized for constructing the body portion .10, although the material of the tubes may be of a heavier gage, if desired, to render the tubessomcwhat stiffer. The long inlet tube 12.has its lower open end 14 positioned and terminating near and slightly above the bottom of the receptacle body portion, as best shown in FIGURE 3. The outlet tube 13, which is much shorter than the tube 12, has its lower end 15 terminating near and below the upper end of the package body portion. Both tubes 12 and 13 extend exteriorly of the package body portion, beyond the top end thereof for a distance of several inches or the like, and which distance may vary somewhat in practice. The two tubes 12 and 13 preferably extend equal distances beyond the top edge of the packagebody portion, exteriorly thereof, as shown. The top ends of both tubes 12 and 13 are completely sealed or' closed at 16 by heat sealing, or the like. The tubes 12 and 13 are received within small openings 17 in the top of the package body portion and heat sealed or otherwise suitably permanently anchored therein in a fluid tight manner. The openings 17 and tubes are spaced apart laterally approximately as shown, and this distance or spacing may be varied somewhat in practice, as found desirable. The tubes 12 and 13 are preferably parallel in their assembled relation to the receptacle body portion or envelope 10. Thus formed, the package containing the solid water soluble material 18 is completely sealed or closed, and no moisture or other foreign matter may enter the package prior to the use thereof. The tubes 12 and 13 form an integral and permanent part of the package and the entire package is flexible and of a shape rendering it readily stackable with other packages of the same type. The package is durable and] quite tough and will not rupture or leak even when subjected to rather rough usage.
In order to use the package for dispensing the fluid soluble material therein onto a lawn or the like, an ordinary garden hose 1? may be employed as depicted in FIGURE 1. A conventional feed and proportioning device 20 of rigid construction and having a venturi throat 21 may be coupled at 22 with a water faucet 23 or the like. The garden hose 19, as best shown in FIG- URE 3,. is coupled at 24 with the other end of the proportioning device 20. The device 20 has a pair of rigid tubular nipples 25-and 26, of relatively small diameter, formed integral therewith, and extending in spaced parallel relation from one side thereof. The nipple 25 com municates with a main interior chamber 27 of the proportioning device 20, while the nipple 26 communicates with the venturi throat 21 as shown in FIGURE 3.
To couple the dispensing package with the device 20, it is merely necessary to sever the plastic tubes 12 and 13 close to their sealed ends 16, which renders both tubes fully open at both ends, and the severed ends of the tubes arethen telescoped over the nipples 25 and 26, as shown in FIGURE 3, in snug fitting relation thereto and forming therewith fluid tight joints. When the parts are properly sized, it will be unnecessary to wrap or bind the tubes 12 and 13, and the same will remain engaged with the nipples 25 and 26 frictionally.
With the package thus assembled to the revice 20, FIG- URE 3, the water supply is turned on and the water will flow through the device 20 and into the garden hose 19. Some water will be diverted through the nipple 25 and through the long inlet tube 12 to the bottom of the package, as shown by the arrows in FIGURE 3. This water gradually fills the package body portion, dissolving and therein.
mixing with the soluble fertilizer, insecticide or the like 7 When the water level within the package rises sufficiently to cover the lower end of the tube 13, the suction created in the venuturi throat 21 will begin to draw or siphon the dissolved material from the package through the outlet tube 13 and nipple 26 and into the venturi throat 21, and from this throat into the garden hose 19 for dispensing onto a lawn, shrubbery or the like. This action will continue as long as the water continues to flow through the garden hose and proportioning device and all of the soluble material in the package will be dissolved in and mixed with the water therein and then siphoned through the tube 13, until the package is substantially empty. When substantially clear water is observed to be discharging from the hose nozzle, the operator may readily remove the package from the device or adapter 20 and replace it with a new package containing a fresh charge of soluble material. The spent package, due to its inexpensive construction, can be discarded after a single usage.
As should now be apparent, the invention provides a package which is highly convenient to market to the customer and equally convenient to use or dispense from, without the necessity for any tools save a pair of scissors or the like for serving the two tubes 12 and 13 close to their sealed ends. The package is leak-proof during use and will not contaminate the hands of the user with fertilizer or other chemicals which might be contained therein. The package is highly compact in construction and generally flat so that a large number of packages may be stacked or placed in a common storage bin in a retail store or the like. They are tough and durable, as previously stated, and will withstand rough usage without rupturing or opening. The entire package is flexible and the side walls thereof are capable of expanding considerably when the water under presure is introduced therebetween, so that a thorough mixing .and dilution of the contents may take place prior to the actual dispensing.
A small filter or strainer 15' is preferably contained near the lower end of outlet tube 13 to prevent the passage of any large particles of material into the outlet tube or device 20, thereby preventing possible clogging of the same.
It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, wthiout departing from the spirit of the invention or scope of the subjoined claims.
