As further illustrated in FIG. 2, the threadable cap 30 includes at least one threaded member 30a. Generally, the threadable cap 30 has sufficient size and dimensions for threadable receipt by a standard agricultural tank (not shown) so that the cap 30 is releasably secured to the opening of the tank with the measuring device 20 positioned in a downward orientation, dispensing any measured fluids into the tank (not shown). By way of example, common fluid holding tanks includes those described in issued U.S. Pat. Nos. 1,316,949; 5,180,190; 5,285,923; 5,365,980; 5,534,318; 5,383,566; 6,189,723; 6,772,702; 7,083,065; 7,168,443; and 8,960,484 the disclosures of which are incorporated herein by reference as it relates to the fluid holding tanks in general suitable for use in connection with the present invention.

(14) One embodiment of the various tanks illustrated in the referenced U.S. patents above includes in a common agricultural spray tank operation where the tank is used for spraying fluids on crops and agriculture products and includes a substantial hollow body with a cylindrical threaded opening, commonly having a 5-inch diameter threaded opening for which the threadable cap 30 is adapted for receipt. The tank (not shown) generally has conventional construction and includes a central portion connecting to two opposing ends with supporting sidewall construction which is generally adapted for supporting and receiving a fluid for transport to a field or lawn for treating vegetation or livestock. As is generally known, the tank measuring device 20, threadable cap 30 and hose restrictor 40 may be fabricated from a chemically non-reactive material suitable for general use on vegetation and livestock.

(15) As further illustrated in FIG. 2, a plurality of raised measurement indicia 16 are located on an integrally formed stepped structure 18 also referred to herein as the stepped measurement structure. Generally, the raised measurement indicia 16 correspond to the sidewall measuring indicia 25 which are located on the cylindrical sidewall 24. However, the stepped structure 18 in FIG. 2 is depicted with both vertical spacing up the cylindrical sidewall and radially outward from the center thereof. This allows a user to readily determine the measurement of any contained tank additives both vertically and radially between the plural raised measurement indicia 16 while looking down into the measuring device 20. In addition, the stepped structure 18 connectably extends along the cylindrical sidewall 24, the measuring device 20 being suitable for containing fluids within the interior presented thereby. A generally arcuate passage 27 extends rearwardly from the stepped structure 18 and outwardly from the cylindrical sidewall 24.

(16) The sidewall measuring indicia 25 and raised measurement indicia 16 may each represent a volume, a ratio, a number, or some other volumetric reference which is used in measuring, diluting and/or adding the additive to the tank (not shown) for spraying upon the desired vegetation and/or livestock and may be redundant or supplemental to each other for use in measuring the additive. The system 10 is generally oriented in the operational configuration (exploded for clarity) in FIG. 8, the measuring device 20 generally oriented with the sidewall and raised measurement indicia 25, 16 being displayed upwardly from the threadable cap 30. The system 10 is generally oriented in the stored configuration (exploded for clarity) in FIG. 9 which while in an stored configuration the measuring device 20 is generally adapted for threaded receipt within a threaded tank opening associated with the tank (not shown). The threadable cap 30 may alternatively include additional circular contours extending circumferentially along the outer cap sidewall 31.

(17) The sidewall measuring indicia 25 may include a centrally positioned reference system with plural measuring indicia associated with an offset, narrowing cylindrical structure with various volumetric markings being located centrally along the sidewall 24 of the measuring device 20. The raised or beveled measurement indicia 16 may be spaced along the stepped structure 18 or alternatively along cylindrical or bossed surfaces (not shown) which extend upwardly along the interior of the measuring device 20 to indicate the volume of the additive being measured for distribution into the tank (not shown) for dispensing therein.

(18) A releasable connection between the measuring device and threadable cap is depicted in FIG. 2 with a hanger 29 including a male portion of a threaded fastener 39 extending upwardly from the threadable cap 30 for threaded receipt by a female portion referred to herein as a cap receiver 21 associated with the measuring device 20. The threaded fastener 39 and cap receiver 21 presenting a releasable mechanical connection jointly referred to as the hanger 29. Although FIG. 2 illustrates the hanger 29 with the male threaded fastener 39 engaged to the female threaded cap receiver 21, various alternative configurations may be utilized for releasably connecting the measuring device 20 to the threadable cap 30 for use in the operational and storage configurations further described herein.

(19) FIG. 2 depicts the arcuate passage 27 angularly oriented and extending upwardly from the threadable cap 30 behind the stepped structure 18. As further illustrated in FIGS. 6-7, the arcuate passage 27 is configured for securely receiving and guiding a typical garden hose 8 inserted through the threadable cap 30 towards the tank (not shown), while the system 10 is secured thereto.

(20) FIG. 3 illustrates the base 36 of the threadable cap 30 with the pivotable hose restrictor 40 positioned along a central channel 35 bisecting a generally raised region of the base 36 presenting a pair of mirrored Ds 36a each extending outwardly from the central channel 35. The hose restrictor 40 includes a hinge member such as a pivotable hinge pin 44 for pivoted operation of the hose restrictor 40 between the open and closed position. The hose restrictor 40 rotates within the central channel 35 about a pair of hinge receivers 38 which are illustrated as being positioned along the outwardly extending raised Ds 36a. The hinge receivers 38 are generally configured for receiving the hinge member 44 during pivoted rotation of the hose restrictor 40 as it moves from the closed position to the open position. In the embodiment of the threadable cap illustrated in FIG. 5, a pair of venting apertures 37 are illustrated along the central channel 35 with the hose restrictor 40 in the open position. The venting apertures 37 may allow for the flow of air through the threadable cap 30 while threadably secured to the tank (not shown) as it is filled by the hose 8.

(21) An alternative embodiment of the invention is shown with the hose restrictor 40 and the threadable cap 30, the hose restrictor 40 being mounted to the threadable cap 30 and being pivotable from a closed position to an open position for passage of the hose 8 through the cap base 36 for filling the tank (not shown) with fluid presented by the hose 8. The hose restrictor 40 includes a top surface 41 and a lower surface 42, the top surface 41 being substantially planar while the lower surface 42 includes a cap engagement ring 43 generally of sufficient size and dimension for being releasably secured to a retainer engagement ring 33 while the hose restrictor 40 is in the closed position. In the open position of the hose restrictor 40, the retainer engagement ring 33 has sufficient size and shape and is generally aligned with the arcuate passage 27 for receiving the hose 8 therethrough as desired.

(22) As depicted in FIG. 2, the hose restrictor 40 is in the closed position while the cap engagement ring 43 extends upwardly from the lower surface 42 and the retainer engagement ring 33 extends downwardly from the central channel 35 for engagement thereat. In the closed position the hose restrictor 40 is rotated forward and the cap engagement ring 43 is positioned for direct engagement with the retainer engagement ring 33. In this position, the top surface 41 is generally coplanar with the pair of raised double Ds 36a. In the open position, as illustrated in FIG. 7, the hose restrictor 40 is pivoted rearwardly with the retainer engagement ring 33 ready for receipt of the hose 8 therethrough. Other configurations may be utilized as desired for releasably connecting the hose restrictor 40 to the threadable cap 30.

(23) FIG. 4 illustrates the measuring device 20 with the stepped structure 18 extending radially from the centrally located cap receiver 21 to the cylindrical sidewall 24 with the arcuate passage 27 extending reawardly therefrom. The dispensing spout 28 also extends outwardly for easy dispensing of any contained additives into the tank (not shown) as desired.

(24) FIGS. 6 -7 illustrates the hose 8 in association with the system 10 with the hose 8 passed through the threadable cap 30 into the arcuate passage 27 and extending rearwardly from the measuring device 20 for fluidic communication with the tank (not shown) when the threadable cap 30 is threadably secured to the tank (not shown). In the depicted embodiment, the hose restrictor 40 is pivoted backwardly towards the open position with the cap engagement ring 43 extending upward and the arcuate passage 27 adapted for and in receipt of the hose 8 through the retainer engagement ring 33 into a hose aperture 33a. the hose aperture 33a is encircled by and presented by the retainer engagement ring 33 and preferably has sufficient size and dimensions for passage of a standard garden hose therethrough for receipt by the arcuate passage 27. Thread 30a extending along the interior of the threadable cap 30 is generally adapted for releasably securing the threadable cap 30 to the hose 8 during use and storage of the system 10.

(25) In the stored configuration, the measuring device 20 is generally secured to the threadable cap 30 by hanger 29 and the threadable cap 30 is threadably secured to the threaded opening of the tank (not shown). As the threadable cap 30 is removed from the threaded opening, the measuring device 30 is moved towards the operational configuration in an upright orientation and ready to receive the tank additive as desired. In both the operational and stored configurations, as illustrated in the embodiment of the hanger 29, the cup fastener 32 extends from the threadable cap 30 and is threadably secured to the centrally located cap receiver 21. Alternatively, the hanger 29 may utilize alternative securing means generally known. In the stored configuration, the measuring device 20 is stored in an upside down orientation with the threadable cap 30 being threadably secured to and at least partially covering the opening of the tank (not shown).

(26) FIGS. 8-9 illustrate an exploded view of the system 10 with the measuring device 20 separated from the threadable cap 30 and the hose restrictor 40. The arcuate passage 27 is further illustrated in FIG. 9 providing rearward access for the hose 8 as it extends through the hose testrictor 40 and the threadable cap 30 into the arcuate passage 27. As further illustrated in FIG. 9, the rear of the stepped structure 18 spans the cylindrical sidewall 24, presenting a hermetic sidewall for containing any contained additives. The illustrated embodiment of the stepped structure 18 guides the hose 8 outwardly and away from the measuring device 20 which may for example be towards the surrounding tank, for direct fluidic communication between the hose 8 and the tank (not shown) while the system 10 is threadable secured to the tank (not shown).

(27) As illustrated in FIG. 2, the measuring device 20 is generally mechanically secured to the threadable cap 30 with the hanger 29. The centrally disposed, hanger 29 generally includes the cap receiver 21 associated with the measuring device 20 and the cup fastener 32 associated with the threadable cap 30, although other fasteners may be utilized including, mechanical, chemical or magnetic to join the measuring device 20 to the threadable cap 30. Alternatively, the measuring device 20 may be integrally formed through known molding or forming processes in fabrication of the threadable cap 30.

(28) In the embodiment depicted in FIG. 9, the measuring device 20 includes an alignment member 23 depicted as a raised or beveled ring for guided receipt by a corresponding structure associated with the threadable cap 30. The alignment member 23 may include a guide 23a to help further align and secure the measuring device 20 with the threadable cap 30.

(29) The arcuate passage 27 is located behind the stepped structure 18 which is adapted for releasable receipt of the typical garden hose 8. The arcuate passage 27 is illustrated as having a generally semicircular channel presented by a pair of arcuate members 27a separated by the outwardly extending rear side of the vertical and horizontal structure 18 positioned within the arcuate passage 27. The arcuate members 27a may be arranged to provide frictional resistance and to limit undesired movement of the hose 8 within the arcuate passage 27, including rotational, lateral and longitudinal movement which may be presented by the hose 8 as fluid moves through the hose 8, when the hose 8 becomes pressurized or when fluid exits one end. In such a way, a recoil force may be presented by the hose 8, which if unclamped would allow the hose 8 to free itself therefore potentially spilling, splattering or spraying fluid or chemical additives. In addition, the arcuate members 27a, in association with the arcuate passage 27, secure the hose 8 as the transmitted fluid presents an upward force on the hose 8. An alternative hose receiver embodiment (not shown) may mechanically connect the hose 8 to an alternative hose receiver (not shown) which allows for fastening of the hose 8 during transmission of fluid into the tank (not shown).

(30) It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
