APPARATUS FOR DISCHARGING FLUID TO THE LAST DROP

The owner has no objection to the facsimile reproduction by anyone of the patent disclosure, as it appears in the Patent and Trademark Office files or records, but otherwise reserves all copyright rights whatsoever.
FIELD OF INVENTION
[0002] This invention is related to an apparatus for discharging fluid which includes a fluid discharge assembly coupled with a container. The discharge assembly includes a tube and die container includes a cavity wherein one end of the tube is secured inside the cavity. As the fluid discharge assembly is rotated around an axial axis of the container, the one end of the tube remains inside the cavity thereby ensuring mat the fluid is discharged completely regardless of the orientation of the apparatus.
BACKGROUND
[0003] Traditional spray bottles, such as those used for cleaning purposes, generally include a spray head having an actuator and a nozzle through which the fluid is discharged. The spray head comprises a tube which acts as a conduit between the fluid inside the bottle and the spray head. When the user actuates the actuator, the fluid is sprayed as a jet through the nozzle and on the desired surface of object.
[0004] A drawback to the traditional spray bottles is that when the fluid level is low and the bottle is tilted during actuation, the entrance end of the tube is no longer in contact with the fluid and therefore the fluid cannot be discharged. As such, the fluid inside the bottle is wasted. [0005] One existing improvement to the traditional spray bottles is lengthening the tube with respect to the length of the bottle so as to ensure the entrance end of the tube remains in contact with the surface of the base of the container. However, the tube rotates with the spray head in a rigid body motion and, as such, only certain angles of tilts are available through which the fluid can be discharged completely.
[0006] Another existing improvement to the traditional spray bottles is to lengthen the tube to such a degree so that the entrance end of the tube remains generally in one location as the spray head is rotated through a 360 degrees turn. Although this improvement purports to allow the fluid to be discharged completely at any angle of tilt, it is susceptible to malfunction. This is because the mechanism relies on the friction forces between the entrance end of the tube and the base. The entrance end of the tube can be displaced from its location if either during manufacturing the length of the tube is made shorter than intended or the viscosity of the fluid is high enough so as to overcome the frictional forces.
[0007] The present invention overcomes these deficiencies by introducing a cavity (or alternatively, an edge, notch, pocket, or reservoir) inside the container where the fluid is stored and placing the entrance end of the tube securely inside the cavity. Specifically, an apparatus for discharging fluid is disclosed comprising a fluid discharge assembly and a container. The fluid discharge assembly comprises a fluid discharge head, a cap, and a tube. The container comprises a hollow body, a base, a mouth, and a cavity inside the container. The entrance end of the tube is placed inside the cavity and the cavity ensures that the entrance end of the tube remains inside the cavity as the spray head is rotated through a 360 degrees turn. As such, the apparatus for discharging fluid of the present invention guaranties that every last drop of the fluid inside the container can be discharged regardless of the orientation of the apparatus. SUMMARY
[0008] In one aspect, an apparatus for discharging fluid is disclosed wherein the apparatus comprises a container for storing fluid, said container comprising a base, a hollow body which is disposed around a perimeter of the base and substantially perpendicular to the base, a mouth which includes an externally threaded section, and a cavity inside the container, a fluid discharge assembly, comprising, a fluid discharge head which includes an actuator and a nozzle, wherein by actuating the actuator the fluid is discharged through the nozzle, a cap which includes an internally threaded section operative to engage the externally threaded section of the mouth of die container so as to fasten the fluid discharge head to the container, wherein die fluid discharge head is rotatably coupled with die cap so as to allow die fluid discharge head to freely rotate around an axial axis of the container without unfastening the fluid discharge head from the container, a tube operative to direct the fluid from inside the container to the fluid discharge head, said tube having a first end and a second end, wherein the first end of the tube is coupled with die fluid discharge head, wherein the second end of the tube is secured inside the cavity so as to allow the fluid discharge head to freely rotate around the axial axis of the container while the second end of the tube remains inside the cavity.
[0009] Preferably, the cavity is located at an intersection between a wall of the body of the container and the base.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
[0039] FIG, 1 depicts a diagram of a perspective view of a preferred embodiment of an apparatus for discharging fluid 100 comprising a container 102 and a fluid discharge assembly 112. The apparatus for discharging fluid 100 is configured so as to allow the user to literally discharge the fluid inside to the last drop.
[0040] The container 102 is used for storing fluid and it comprises a base 104 and a hollow body 106 which is disposed around the perimeter of the base 104 and substantially perpendicular to the base 104. The container 112 further comprises a mouth 108 which includes an externally threaded section (not seen) and a cavity 110 which resides inside the container 102. The container 102 can be made from any one of the plastic material, metallic material, and ceramic material, or a combination thereof.
[0041] The fluid discharge assembly 1 12 comprises a fluid discharge head 114 which in turn includes an actuator 116 and a nozzle 118. As is known to artisans of ordinary skill, as the actuator 116 is pressed inwardly (actuated) the fluid is discharge through the nozzle 118. The fluid discharge assembly 112 further comprises a tube 122 which directs the fluid from inside the container 102 to the fluid discharge head 114. The tube 122 has a first end (not seen) which is coupled with the fluid discharge head 114 and a second end 124 which is secured inside the cavity 110. As the discharge head 114 is rotated through 360 degrees around an axial axis of the container 102, the second end 124 remains inside the cavity 110. As discussed in more detail below, this ensures that the fluid inside the container 102 is guided towards the cavity 110 regardless of the orientation of the apparatus for discharging fluid 100. [0042] The fluid discharge assembly 112 further comprises a cap 120 which includes an internally threaded section (not seen) which operates to engage the externally threaded section of the mourn 108 of the container 102 so as to fasten the fluid discharge head 114 to the container 102. The cap 120 and the fluid discharge head 114 are rotatably coupled together, such as in a journal or plane bearing, so as to allow the fluid discharge head 114 to freely rotate around the axial axis of the container 102 without unfastening the fluid discharge head 114 from the container 102.
[0043] The apparatus for discharging fluid 100 incorporates the cavity 110 so as to allow the user to discharge every last drop of the fluid inside the container 102. In mis preferred embodiment, the base 104 is generally rectangular, the hollow body 106 is generally a cuboid, and the mouth 108 is generally cylindrical in shape. The cavity 110 is located at an intersection between a wall of the body 106 of the container 102 and the base 104. More specifically, the cavity 110 is located in midpoint of an edge of the base 104 and the wall of the body 106. In an alternative embodiment, the cavity 110 is located at a corner of the container 102, hence, an intersection between a first wall of the body 106 of the container 102, a second wall of the body 106 of the container 102, and the base 104. As is shown in this FIG. 1 and further in FIG. 2, a bottom surface of the cavity 110 protrudes below a bottom surface of the base 104.
[0044] FIG. 2 depicts a cross sectional view of an apparatus for discharging fluid 200 such as the one shown in FIG. 1. This cross sectional view provides a clearer illustration of the components of the apparatus for discharging fluid 200. Specifically, the fluid discharge apparatus 200 includes a container 202 having a base 204, a hollow body 206, a mouth 208 which includes an externally threaded section, and a cavity 210. The base 204 has a generally convex surface inside the body 206 and associated concave surface outside of the body 206. In an alternative embodiment, the base 204 has a generally sloped surface inside the body 206 of the container 202 whose slope is downward toward the cavity 210.
[0045] The apparatus 200 further includes a fluid discharge assembly 212. The fluid discharge assembly 212 includes a fluid discharge head 214 which comprises an actuator 216 and a nozzle 218. The fluid discharge assembly 212 further includes a tube 222 which has a first end 226 and a second end 224. The tube 222 directs fluid 228 from inside the container 202 to die fluid discharge head 214. The fluid 228 can be any one of a liquid disinfectant, a liquid soap, and a liquid fragrance. The first end 226 of the tube 222 is coupled with the fluid discharge head 214 and the second end 224 is secured inside the cavity 210 as the fluid discharge head 214 freely rotates around an axial axis, such as the vertical axis of the apparatus 200, of the container 202 while the second end 224 of the tube 222 remains inside the cavity 210.
[0046] This cross sectional view clearly shows a cap 220 which is included in the fluid discharge assembly 212. The cap 220 is threaded internally and operates to engage the externally threaded section of the mouth 208 of the container 202 so as to fasten the fluid discharge head 214 to the container 202. The cap 220 is rotated and its internal thread engages the external thread of the mouth 208 which in turn fastens the fluid discharge head 214 to the container 202. However, the fluid discharge head 214 is free to rotate 360 degrees about the vertical axis while the cap 220 remains stationary and thus maintaining the fastening force between the fluid discharge assembly 212 and the container 202. In a preferred
embodiment the length of the tube 222 is greater than the length of the container 202 so that when the fluid discharge head 214 is fastened to the container 202 by rotating the cap 220, a difference between the length of the tube 222 and the length of the container 202 is such that the difference generates a compressive force between the tube 222 and the base 204 so as to further ensure that the second end 224 of the tube 222 remains inside the cavity 210.
[0047] FIG. 3A depicts a cutaway cross sectional view of a lower section 300 of an apparatus for discharging fluid such as the one shown in FIG. 2. In this preferred embodiment a cavity 306 is inside the container and an external surface of the cavity 306 protrudes from an external surface of a wall of the body 304. A second end 310 of a tube 308 is secured inside the cavity 306 which ensures that fluid 312 inside the container is discharged completely regardless of the orientation of the apparatus. [0048] FIG. 3B shows a side view of the lower section 300 of the apparatus for discharging fluid shown in FIG. 3 A. In this figure it is further illustrated that the location of the cavity 306 inside the container is at an intersection between a wall of the body 304 of the container and the base 302 and at midpoint along an edge of the base 302. The shape of the cavity 306 is generally rectangular. This figure further illustrates how the second end 310 remains inside the cavity 306 while the tube 308 may generally move about inside the cavity 306 as the fluid discharge head (not shown) is rotated about the vertical axis.
[0049] FIG. 4A shows a side view of a preferred embodiment of an apparatus for discharging fluid 400 and its components according to the present invention. It shows a downwardly orientation of the apparatus 400 with respect to the level of fluid 428 inside a container 402 of the apparatus 400 and how a fluid discharge head 414 of a fluid discharge assembly 412 of the apparatus 400 may rotate 180 degrees about an axial axis 432 of the container 402 to an upwardly orientation (dashed lines) while a second end 424 of a tube 422 of the fluid discharge assembly 412 remains inside a cavity 410 of the container 402.
[0050] In this illustrative embodiment, the user utilizes the apparatus 400 to spray the fluid 428 at an object in a downwardly orientation. The second end 424 of the tube 422 is inside the cavity 410 and the fluid 428 can be discharged completely and to the last drop at this orientation. The convex surface of the base 404 is further instrumental to direct the fluid 428 toward the cavity 410 where the second end 424 of the tube 422 resides for efficient discharge of the fluid 428 to the last drop.
[0051] Should the user utilize the apparatus 400 to spray at an object that is orientated upwardly, all the user is required to do is to rotate the fluid discharge head 414 around the axial axis 432 and the cavity 410 ensures that second end 424 of the rube 422 remains inside the cavity 410 thereby allowing the user to discharge every last drop of the fluid 428 out of the apparatus 400.
[0052] FIG. 4B shows the side view the apparatus for discharging fluid 400 shown in FIG.4A in the downwardly orientation at some later time when the fluid 428 inside the container 402 has been all but completely discharged out of the apparatus 400 showing the last few drops of the fluid 428 inside the cavity 410. As can be seen in this figure, the base 404 has an upper surface that is convex and a bottom surface that is concave. In an alternative embodiment, the base 404 has a generally sloped surface inside the body 406 of the container 402 whose slope is downward toward the cavity 410. As can be seen in this figure, an external surface of the cavity 410 protrudes from an external surface of a wall of the body 406 of the container 402. This configuration allows the user to see precisely where the cavity 410 is located inside the container 402.

The fluid discharge assembly also comprises a tube 508 (partially shown) which includes a first end 510. The first end 510 is coupled with the fluid discharge head 502 so as to rotate with the fluid discharge head 502 in a ridged body motion. In an alternative embodiment, die first end 510 is coupled with the fluid discharge head 502, such as in a journal or plane bearing, so as to allow the fluid discharge head 502 to freely rotate around an axial axis of the container without rotating the tube 508. A cap 516 of the fluid discharge assembly includes an internally threaded section which engages an externally threaded section of a mouth 512 of the container thereby fastening the fluid discharge head 502 to the container while allowing the fluid discharge head 502 to freely rotate around die axial axis of the container without unfastening the fluid discharge head 502 from the container.
[0054] FIG. 6 depicts an exploded view of an apparatus for discharging fluid 600, such as the one shown in FIG. 5, illustrating die axial positions of two annular rings 620 and 624 and the cylindrical tubular component 622.

The apparatus 600 further comprises a container 612 (partially shown) which includes a hollow body 614 (for instance, thin walled) and a mouth 616 which has an externally threaded section which is used to engage the internally threaded section of the cap 610.
[0055] The first annular ring 620 has a first lower surface and a first upper surface where the first lower surface is in contact with the mouth 616 of the container 612. The cylindrical tubular component 622 has a circular shoulder section. As shown in this figure, the cylindrical tubular component 622 can be inserted into the first annular ring 620 where a lower surface of the circular shoulder section of the cylindrical tubular component 622 contacts the first upper surface of the first annular ring 620. The second annular ring 624 has a second lower surface and a second upper surface where the second lower surface is in contact with an upper surface of the circular section of the cylindrical tubular component 622 and the second upper surface of the second annular ring 624 contacts the fluid discharge head 608. The first annular ring 620 and second annular ring 624 are gaskets which operate to seal by filling the space between the contacting surface between the annular rings 620 and 624 on the one hand, and the mouth 616, the cylindrical tubular component 622, and the fluid discharge head 60S, so as to prevent leakage of fluid between these components while under compression developed by tightening the cap 610. Such Gaskets can be made from rubber, silicone, or cork materials.
