Detailed Description

[0024] FIGS. 1-4 show a dosing bottle arrangement generally at 10. The dosing bottle arrangement 10 has advantages, in that the user will not have to come in contact with the liquid product in the bottle. In addition, the dosage will be fast and precise. It is easy to handle, as the dosing volume can be preset and a reading of a measuring scale is unnecessary. It also provides for optimal dosage through a number of adjustable volume levels. The number of adjustable volume levels can vary. In the non-limiting example shown in this disclosure, there are at least four adjustable volume levels, but that is an example only. There can be 2, 3, 4, 5, 6, 7, 9, 10 or more adjustable volume levels.

[0025] The dosing bottle arrangement 10 include a container wall 14 surrounding an interior volume 16. The interior volume 16 will hold a liquid. The liquid can be any type of liquid in which a proper measured dose is needed while handling. For example, the liquid can be the types of chemicals that are used in aquariums for maintaining cleanliness or to ensure a good healthy aquarium environment.

[0026] The container wall 14 is preferably made from an elastically deformable material. An elastically deformable material will allow the container wall 14 to be squeezed by the user with the users hand in order to move liquid from the liquid volume 16 to a remaining portion of the bottle arrangement 10.

[0027] The elastic deformation then returns to the original shape, for use again.

[0028] The container 12 further includes a protruding neck 18. The neck 18 has an open mouth 20 in fluid communication with the interior volume 16. The neck 18 includes structure to allow for removable fastening of other portion of the bottle arrangement 10. In this embodiment, the neck 18 includes threads 22 along the outer surface 24 of the neck 18.

[0029] Still in reference to FIG. 5, the dosing bottle arrangement 10 further includes a dip tube, or riser 26. The riser 26 is an open tube which extends from the interior volume 16 of the container 12 and through the open mouth 20 of the neck 18. The riser 26 will convey liquid from the interior volume 16 through the interior of the riser 26 through the neck 18 and out through an open end 28 to other portions of the dosing bottle arrangement 10.

[0030] The dosing bottle arrangement 10 further includes a cap piece 30. The cap piece 30 has an outer surrounding wall 32. The outer surrounding wall 32 is removably attached to the neck 18. While many different possibilities exist, in the example shown, an inner surface 34 of the outer surrounding wall 32 includes threads 36, which mate with the threads 22 on the neck 18. This allows for easy and convenient removal of the cap piece 30 from the container 12.

[0031] The outer surrounding wall 32 further includes a plurality of axially extending tracks 38, in the form of indentations that extend along an outer surface 40 of the outer surrounding wall 32.

[0032] The cap piece 30 further includes a gusset arrangement 44 (FIG. 5). The gusset arrangement 44 radially extends from the outer surrounding wall 32 and within the open mouth 20 of the neck 18. As can be seen in FIG. 5, the cap piece 30 is folded over an end rim 19 of the neck 18, to join the outer surrounding wall 32 with the gusset arrangement 44. The gusset arrangement 44 forms an internal V-shape having an open recess at 46 within the mouth 20 of the neck 18. A most radially interior part of the V- section of the gusset arrangement 44 forms an interior cylinder 48 which circumscribes and surrounds the riser 26.

[0033] The cap piece 30 further includes a standpipe 50 extending from the gusset arrangement 44. In the example shown, the standpipe 50 extends from an interior aperture 52 of the interior cylinder 48. The standpipe 50 includes a tubular wall 54 connected to the riser 26. In particular, the tubular wall 54 is connected to the riser 26 at the open end 28 of the riser 26.

[0034] The tubular wall 54 of the standpipe 50 has a closed end 56 opposite of the end which connects to the riser 26. Along the body of the tubular wall 54 is one or more return openings 58. The return openings 58 allow for liquid which is conveyed from the interior volume 16 of the container 12, through the riser 26 to flow through the tubular wall 54 of the standpipe 50 and then flow through the return opening 58 to a remaining portion of the bottle arrangement 10. The return opening 58 has an associated predetermined liquid dosing amount associated with it.

[0035] It should be understood that there can be several return openings 58, each return opening being associated with a predetermined liquid dosing amount. In this example, there are four return openings 58. These include a first return opening 60, a second return opening 62, third return opening 64, and fourth return opening 66. Each of the return openings 60, 62, 64, 66 is both radially spaced and axially spaced from each of the other return openings 60, 62, 64, 66. The axial spacing between them allows for each return opening 60, 62, 64, 66 is correlated with a predetermined liquid dosing amount. The radial spacing between each of the return openings 60, 62, 64, 66 allows for a radial selection of which predetermined liquid dosing amount is desired.

[0036] The interior cylinder 48 of the cap piece 30 includes a plurality of circumferentially arranged detents 49, being radially aligned with the return openings 58. The detents 49 will receive projections from a closure member 70, as further described. [0037] The bottle arrangement 10 further includes closure member 70. The closure member 70 has a surrounding enclosure 72 rotatably attached to the cap piece 30 and defining an interior dosing volume 74 there within. At an upper portion of the closure member 70 is a dispenser opening 76. When the bottle arrangement 10 is an open position, the dispenser opening 76 is in open fluid communication with the interior dosing volume 74, to allow for liquid within the interior dosing volume 74 to flow through the dispenser opening 76. FIG. 1 shows the bottle arrangement 10 when in a closed position. In a closed position, the standpipe 50 is blocking or plugging the dispenser opening 76.

[0038] The closure member 70 is preferably made from a transparent material to allow for visual inspection of the interior dosing volume 74.

[0039] The closure member 70 includes visual markings 42 on the surrounding enclosure 72 of the closure member 70. The visual markings 42 can show a number, representing the number of fluid ounces or milliliters that will be dosed (allowed to flow into the interior dosing volume 74), when the bottle arrangement 10 is used.

[0040] The outer surrounding wall 32 of the cap piece 30 includes a visual indicator in the form of a geometric figure, such as a triangle, or an arrow 43, such that the closure member 70 can be rotated to match the visual marking 42 on the closure member with the arrow 43 to select the desired dosing amount.

[0041] The closure member 70 further includes a tube 78. The tube 78 is secured to the surrounding enclosure 72 within the interior dosing volume 74 via a connection piece 82. The connection piece 82 is received within the recess 46. The tube 78 is positioned to be in covering relation to the tubular wall 54 of the standpipe 50. The tube 78 includes an aperture 80 (FIG. 2). The aperture 80 can be aligned with one of the return openings 58 to allow for liquid to flow from the interior volume 16 of the container 12, through the riser 26, through one of the return openings 60, 62, 64, 66, and through the aperture 80 into the interior dosing volume 74.

[0042] The connection piece 82 includes projections 84, which are received by the detents 49. An axial position of the projections 84/detents 49 are correlated to the height level / axial position of the closure member 70 relative to the cap piece 30 so that the correction return opening 60, 62, 64, 66 is exposed, corresponding to the selected number of fluid ounces or milliliters to fill the dosing volume 74.

[0043] In general, the closure member 70 is axially movable relative to the cap piece 30 between a closed position (FIGS. 1 and 2) and an open position (FIGS. 3-5). The closed position being the position in which the tube 78 covers all of the return openings 60, 62, 64, 66 in the tubular wall 54. The open position is the position in which the aperture 80 in the tube 78 is in open communication with a selected one of the return openings 58, such that liquid in the interior volume 16 of the container 12 can flow through the riser 26 and through the selected return opening 58 and into the interior dosing volume 74.

[0044] The surrounding enclosure 72 is rotatable relative to the cap piece 30 to a selected desired liquid amount for the interior dosing volume 74. The relative rotational position of the surrounding enclosure 72 and the cap piece 30 places the tube aperture 80 in radial alignment with one of the return openings, 60, 62, 64, 66.

[0045] The above bottle arrangement 10 can be used in as part of a method of providing a measured dose of a liquid. The method includes selecting a desired liquid dosing amount by rotating the closure member 70 relative to cap piece 30 and radially align an aperture 80 in a tube 78 of the closure member 70 with a return opening 60-66 in tubular wall 54 of standpipe 50 of the cap piece 30.

[0046] The method further includes axially moving the closure member 70 relative to the cap piece 30 from a closed position to an open position to put the aperture 80 in open communication with the return opening 60-66.

[0047] The method can further include squeezing container 12 having riser 26 to move liquid in the interior volume 16 of the container 12 through the riser 26 and through the return opening 60-66 and into the interior dosing volume 74 of the closure member 70. [0048] The step of squeezing the container 12 includes squeezing the container wall 14 surrounding the interior volume 16 of the container 12; the container 12 has protruding neck 18; and the neck 18 having open mouth 20 in communication with the interior volume 16; the riser 26 extends from the interior volume 16 and through the open mouth 20 of the neck 18.

[0049] The step of selecting a desired liquid dosing amount includes using the cap piece 30; the cap piece 30 having outer surrounding wall 32 removably attached to the neck 18; gusset arrangement 44 radially extending from the outer surrounding wall 32 and within the open mouth 20 of the neck 18; and the standpipe 50 extending from the gusset arrangement 44; the standpipe 50 including the tubular wall 54 connected to the riser 26 at one end, an opposite closed end 56, and one or more return openings 60-66 in the tubular wall 54.

[0050] The step of selecting a desired liquid dosing amount includes rotating the closure member 70, the closure member having: a surrounding enclosure 72 rotatably attached to the cap piece 30 and defining an interior dosing volume 74 and a dispenser opening 76; the tube 78 being secured to the enclosure 72 within the interior dosing volume; wherein the closure member 70 is axially movable relative to the cap piece 30 between the closed position and the open position; the closed position including the tube 78 covering all of the return openings 60-66 in the tubular wall 54; and the open position including the aperture 80 in the tube 78 being in open communication with one or more of the return openings 60-66, such that a liquid in the interior volume 16 of the container 12 can flow through the riser 26 and through the return opening 60-66 and into the interior dosing volume 74.

[0051] The step of rotating the closure member 70 includes moving the surrounding enclosure 72 relative to the cap piece 30 and placing the tube aperture 80 in radial alignment with one of the return openings 60-66. [0052] The method includes the outer surrounding wall 32 of the closure member 70 includes visual markings 42 indicative of a predetermined liquid dosing amount associated with each of the return openings 60-66; and the step of selecting a desired liquid dosing amount includes rotating the closure member 70 relative to the cap piece 30 to align a marking 42 on the closure member 70 with the visual marking 43 on the cap piece 30.

[0053] The above represents example principles. Many embodiments can be made using these principles.
