Bottle and free flow filter bottle

Abstract

A bottle is provided that incorporates a free flow filter that can passively filter water by the action of gravity when a user drinks from the bottle. The bottle uses an umbrella valve to discharge air from the filter into the body of the bottle such that the bottle provides a continuous flow of filtered water when water is poured out of the bottle. In an embodiment, the umbrella valve moves from a closed position to an open position when at least a threshold pressure is applied to the diaphragm of the valve. When the umbrella valve is in the open position, air may be expelled from the filter and into the body of the bottle.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to currently pending U.S. provisional patent application serial number 63 / 195,944, filed on June 2, 2021, entitled “FREE FLOWFILTER WATER BOTTLE,” the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The utility model generally relates to a water bottle filter, and more particularly to a water bottle filter that filters water when a user pours water from the bottle. Background Art

[0004] It is challenging for consumers to filter water "on the go". Therefore, some consumers purchase bottled water or resort to drinking unfiltered tap water. Bottled water purchased from a store is expensive and wasteful for the environment, and the bottle is used only once and then thrown away. On the other hand, unfiltered tap water may contain chemicals and particles that give the water an unpleasant taste or may be harmful.

[0005] To allow consumers to obtain filtered water on the go, manufacturers have developed reusable water bottles that incorporate water filters. Typically, these bottles are provided as squeeze bottles, or alternatively as bottles with straws. Both types of bottles present problems for the user.

[0006] Squeeze bottles require the user to squeeze the outer surface of the bottle to force the water through the filter and out of the bottle. Unfortunately, people with limited hand strength are unable to squeeze the bottle hard enough to drive the water through the filter and out of the bottle. Furthermore, it is very difficult, if not impossible, to maintain a continuous flow of water from the bottle.

[0007] Straw bottles require the use of a straw to draw water through the filter and out of the bottle. Straws are inconvenient because they must be cleaned regularly and can be misplaced when removed from the bottle. In addition, people with limited lung capacity may not be able to draw water through the filter and up the straw, preventing them from fully using the bottle. Utility Model Content

[0008] The present invention overcomes many of the disadvantages and limitations of the above-described prior art devices. The present invention described includes several embodiments of a free-flow filter water bottle (hereinafter referred to as a "bottle"). The bottle includes a free-flow filter (hereinafter referred to as a "filter") that can passively filter water when a user drinks or pours water from the bottle. More specifically, gravity is sufficient to cause water to flow through the filter and out of the bottle.

[0009] According to some aspects of the present invention, a bottle is provided, characterized in that the bottle includes: a filter element that can be selectively engaged with the bottle; a filter housing, in which the filter element is retained in the filter housing; and an umbrella valve that can be engaged with the filter element, the umbrella valve including a diaphragm having a flexible body and a convex shape, wherein the diaphragm maintains the convex shape until a force exceeding a threshold is applied to the diaphragm and the diaphragm is positioned inside the filter housing, wherein, when liquid is poured from an opening in the bottle and a force exceeding the threshold is applied to the umbrella valve, the umbrella valve expels air from the filter element into the interior of the bottle.

[0010] According to some aspects of the present invention, a bottle is provided, characterized in that the bottle includes: a cap, which can be selectively engaged with the body of the bottle; a filter element, which can be selectively connected to the cap; a filter housing, in which the filter element is retained in the filter housing; and an umbrella valve, which is connected to the filter element, the umbrella valve includes a diaphragm, the diaphragm has a flexible body and a convex shape, wherein the diaphragm maintains the convex shape until a force exceeding a threshold is applied to the diaphragm and the diaphragm is positioned inside the filter housing, and wherein, when a pressure below a force below the threshold is applied to the diaphragm of the umbrella valve, the umbrella valve is configured to prevent air from being discharged from the filter element into the bottle.

[0011] According to other aspects of the present invention, a free-flow filter bottle is provided, characterized in that the bottle includes: a body having an interior; a filter element positioned and located in the interior of the bottle; a filter housing, wherein the filter element is retained in the filter housing; and a valve, the valve including a diaphragm having a flexible body and a convex shape, wherein the diaphragm maintains the convex shape until a force exceeding a threshold is applied to the diaphragm, the valve being configured to prevent air from flowing from the filter element into the interior of the bottle when the valve is in a closed position and the diaphragm is positioned in the interior of the filter housing.

[0012] The filter may include a filter element retained within a filter housing. As water passes through the filter element, the filter element may capture chemicals and particulates present in the water. The filter element may be composed of carbon fibers (or other materials known in the art) that help remove chlorine, particulates, and other substances from the water. Water may flow into the filter element by passing through an aperture located on the filter housing that extends through the filter housing.

[0013] The filtered water can be poured from the bottle simply by the user tilting the bottle to drink from the bottle. The umbrella valve can facilitate the smooth flow of water from the bottle. The umbrella valve can be attached to a cap inside the filter housing and can vent air from the filter and into the bottle when the user drinks from the bottle.

[0014] Initially, when the opening of the bottle is tilted downward, gravity can draw water out of the bottle. As the water leaves the bottle, air can flow into the bottle and into the filter, where the air can be captured by the umbrella valve within the filter. As the air continues to flow into the bottle, the force exerted by the air on the umbrella valve can increase until the force exceeds a threshold value. When the force exceeds the threshold value, the umbrella valve preferably opens. Once the umbrella valve opens, the air in the filter can be discharged into the interior of the bottle, equalizing the air pressure inside and outside the bottle. This discharge process (and the corresponding air pressure equalization) can allow water to flow out of the bottle in a continuous stream. When the water leaves the bottle and the air is discharged into the interior of the bottle, the water can pass through the orifice of the filter housing, through the filter, and leave the bottle.

[0015] From time to time, as the user continues to pour water from the bottle, the force applied by the air to the umbrella valve can drop below a threshold. When the force drops below the threshold, the umbrella valve can close. Once the force of the air from inside the filter exceeds the threshold again, the umbrella valve can reopen. As the umbrella valve opens and closes, water can continuously flow through the filter and out of the bottle.

[0016] The above process can continue until the user stops pouring water from the bottle or the bottle is emptied. After water stops pouring from the bottle, air may no longer enter the filter, and the umbrella valve can be closed, so that air is no longer discharged into the interior of the bottle.

[0017] These and other aspects and advantages of the present invention will become apparent to those skilled in the art after considering the following detailed description in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Although the present disclosure is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will be described in detail herein. However, it should be understood that the drawings and detailed description presented herein are not intended to limit the present disclosure to the specific embodiments disclosed, but on the contrary, are intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims. DETAILED DESCRIPTION

[0026] The present invention will now be described with reference to the accompanying drawings, in which like reference numerals refer to like components throughout. For the purpose of clearly illustrating the features of the present invention, the proportional relationship of the elements does not have to be maintained in the accompanying drawings.

[0027] Figure 1 A bottle 5 and a filter 10 are shown, which filter 10 can be used to passively filter water when a user drinks from the bottle 5. When the filter 10 is used, it can be fixed within the bottle 5 as described below.

[0028] The bottle 5 consists of a body 15 and a cap 20 that can be releasably attached to the body 15. The body 15 can be arranged in the form of a hollow cylinder with thin side walls so that the bottle 5 can contain fluids (including but not limited to water). The body 15 can be made of a resilient waterproof material (such as plastic). The body 15 can also have a top portion 25, and the cap 20 is attached to the top portion 25. In alternative embodiments, the bottle 5 can adopt an almost unlimited number of known and reasonably foreseeable alternative shapes and configurations.

[0029] The cap 20 can be provided in the form of a cylinder, although other shapes are also foreseeable. When the cap 20 is attached to the top portion 25, the cap 20 can help prevent liquid from spilling from the bottle 5 when the bottle 5 is used or otherwise tipped over. The diameter of the cap 20 can be substantially the same as or slightly larger than the top portion 25, so that the cap 20 can be attached to the top portion 25 by tightening the cap 20 to the top portion 25 due to a friction fit or by other methods that will be understood by those skilled in the art. Similarly, the cap 20 can be removed from the top portion 25 by a twisting motion or a pulling motion. When the cap 20 is removed from the bottle 5, the user can fill the bottle 5 with water as needed.

[0030] The filter 10 may be provided in the form of a cylinder. The diameter of the filter 10 is smaller than the diameter of the body 15 so that the filter 10 may be accommodated within the bottle 5. When inserted into the bottle 5, the filter 10 may use known or reasonably foreseeable methods and materials to remove chemicals and particulates (e.g., chlorine and dissolved solids) from water passing through the filter 10. Once the filter 10 has reached the end of its useful life, the user may remove the filter 10 from the bottle 5 and replace it with another filter.

[0031] Go to Figure 2 , the filter 10 may include a filter element 30 having a body 35. The body 35 is shown as being in the shape of a cylinder, but other shapes are also foreseeable. The filter element 30 may have a channel 40 extending through the length of the body 35. When the user drinks from the bottle 5, water may permeate through the body 35 of the filter element 30 and into the channel 40. The body 35 is preferably constructed of a material (such as carbon fiber) that can filter chlorine, particles, and other substances from the water as it travels through the body 35.

[0032] The filter housing 45 may surround the filter cartridge 30 to help protect the filter cartridge 30. The filter housing 45 may be provided in the shape of a hollow cylinder having a diameter slightly larger than the diameter of the filter cartridge 30. The filter housing 45 may have a plurality of apertures 50 extending through its surface so that the water 5 in the bottle flows freely into and out of the filter housing 45, and thus freely into and out of the filter cartridge 30.

[0033] A filter adapter 55 may also be provided, which is generally in the form of a cylinder. The filter adapter 55 may be used to selectively attach the filter 10 to a cover, such as the cover 20 (not shown). The bottom portion 60 of the filter adapter 55 may be narrower than the middle portion 65. The bottom portion 60 may be attached to the filter element 30, and the middle portion 65 may be attached to the filter housing 45. The middle portion 65 may be attached to the filter housing 45 by gluing, threading, or other attachment means known to those skilled in the art. The top portion 70 of the filter element 30 may be attached to the cover 20 in a variety of ways, including but not limited to threaded engagement or friction fit.

[0034] The O-ring 75 can be provided in the shape of a thin ring and can be attached to the top portion 70 of the filter adapter 55. The O-ring 75 can be made of silicone or another flexible waterproof material. When the filter adapter 55 is attached to the cap 20, the O-ring 75 can help form a waterproof seal between the filter adapter 55 and the cap 20. When the user drinks from the bottle 5, the seal can help prevent filtered water from leaking into the body 15 of the bottle 5 and / or unfiltered water from leaking into the cap 20.

[0035] A cap 80 may be provided for attachment to the filter cartridge 30 in the form of a circular body 85 having thin sidewalls. Two concentric circular wall members (a first wall member 90 and a second wall member 95) may protrude upward from the circular body 85. The diameter of the first wall member 90 may be substantially the same as or just larger than the diameter of the filter cartridge 30. The diameter of the second wall member 95 may be substantially the same as or just smaller than the diameter of the channel 40. Thus, a bottom portion 97 of the filter cartridge 30 may be received by the cap 80 and retained between the wall members 90, 95. The filter cartridge 30 is attached to the cap 80 via friction fit, gluing, or by other methods known or foreseeable in the art.

[0036] The valve provided herein as an umbrella valve 100 is preferably engageable with the cap 80. The umbrella valve 100 may be constructed of a flexible, waterproof material such as silicone. The umbrella valve 100 may allow air to escape from the filter 10 while the user is drinking from the bottle 5. More particularly, the umbrella valve 100 may allow water to flow freely through the filter 10 and out of the bottle 5 while the user is drinking from the bottle 5.

[0037] exist Figure 3 , the umbrella valve 100 is shown received within the cap 80 in a closed position, which may occur when the bottle 5 is not in use. The umbrella valve 100 preferably includes a septum 105 (see Figure 4) and a stem 110 extending upwardly from the diaphragm 105. The stem 110 may be a thin, tapered, conical shape that is attached to or integrally formed with the diaphragm 105. When the umbrella valve 100 and the cap 80 are coupled to each other, the stem 110 of the umbrella valve 100 may be received in the cap 80. When the umbrella valve 100 is received by the cap 80, the diaphragm 105 may abut a bottom surface 115 of the cap 80. When the umbrella valve 100 is in the closed position, the diaphragm 105 may form a seal with the bottom surface 115 such that air is blocked from flowing through the cap 80. More specifically, the umbrella valve 100 may be adapted to prevent air from being exhausted through the cap 80. The umbrella valve 100 may remain in the closed position until a force applied to the diaphragm 105 exceeds a threshold value, as described below.

[0038] The diaphragm 105 may have a flexible, thin body and a convex shape (wherein the stem 110 protrudes upward from an inwardly curved portion of the diaphragm 105). The diaphragm 105 may retain this convex shape unless a force exceeding a threshold value is exerted on the diaphragm 105, as described below.

[0039] A knob 120 may be provided on the stem 110 of the umbrella valve 100. The knob 120 may be a protrusion having a larger diameter than other portions of the stem 110. When the umbrella valve 100 is received in the cap 80, the knob 120 may help prevent the umbrella valve 100 from being displaced out of the cap 80 due to air being exhausted through the cap 80 when the bottle 5 is in use.

[0040] like Figure 5 As shown, the cap 80 can have a first orifice 125 and a plurality of second orifices 130 extending through its surface. The orifice 125 can be circular and disposed at or near the center of the cap 80. When the umbrella valve 100 is coupled to the cap 80, the orifice 125 can receive the stem 110 of the umbrella valve 100. The orifice 130 can be disposed radially distally relative to the orifice 125. When the user drinks from the bottle 5, the orifice 130 can allow air to be exhausted through the cap 80 and, therefore, exhausted from the filter 10 (not shown).

[0041] Go to Figure 6 , the filter 10 is attached to the cap 20 of the bottle 5 via the filter adapter 55. The filter adapter 55 may have threads 135 that allow the filter adapter 55 to be coupled to corresponding threads (not shown) on the cap 20. When an upward force is applied to the filter adapter 55, the filter adapter 55 may be received into the cap 20 by rotating the filter adapter 55 in a first direction. Then, when a downward force is applied to the filter adapter 55, the filter adapter 55 may be removed from the cap 20 by rotating the filter adapter 55 in a second direction. In alternative embodiments, the filter adapter 55 may be attached to the cap 20 by a friction fit or by other means that will be understood by those skilled in the art.

[0042] The filter adapter 55 may also include flanges 145 that may receive a top section 150 of the filter cartridge 30 and further help secure the filter cartridge 30 within the filter adapter 55 via a friction fit. Additionally, the filter adapter 55 may have a bore 155 extending through a center portion thereof that may align with the channel 40 of the filter cartridge 30 so that water may flow from the channel 40 and out of the cap 20 when the user drinks from the bottle 5.

[0043] When the user wishes to pour or drink water from the bottle 5, the user can open the cap 20 using a known mechanism and tilt the bottle 5 toward their mouth. As water pours from the bottle 5 due to gravity, the air pressure within the bottle 5 decreases as the air within the interior 160 of the bottle 5 expands to occupy the space vacated by the water leaving the bottle 5. The pressure difference between the interior 160 and the surrounding atmosphere allows air from the atmosphere to enter the bottle 5 via the cap 20. More specifically, the air entering the bottle 5 travels from the opening in the cap 20, passes through the bore 155, and enters the channel 40. Finally, the air flows through the channel 40 and flows to the cap 80.

[0044] Initially, when air first enters the bottle 5 during the above process, the umbrella valve 100 can be in a closed position. Therefore, air trapped within the filter 10 during use can exert a force on the diaphragm 105. As the user continues to pour water out of the bottle 5, more air can enter the bottle 5, and the force exerted by the air on the diaphragm 105 can increase. Eventually, the force exerted by the air to the diaphragm 105 can exceed a threshold value, and the umbrella valve 100 can move to an open position. When the umbrella valve 100 is in the open position, the diaphragm 105 can be lifted away from the bottom surface 115 of the cap 80, and air can flow through the space formed between the diaphragm 105 and the cap 80. In fact, when the umbrella valve 100 is open, air can flow around the diaphragm 105 and flow into the interior 160 of the bottle 5.

[0045] From time to time, when the user pours water from the bottle 5, the force applied by the air to the umbrella valve 100 may drop below a threshold, and the umbrella valve 100 may return to the closed position. Once the force applied by the air within the filter 10 exceeds the threshold, the umbrella valve 100 may reopen, which in turn may allow air to exit the filter 10 and into the interior 160 of the bottle 5. This process may repeat itself during use.

[0046] As air is exhausted into the interior 160 of the bottle 5, and as the user continues to pour water out of the bottle 5, water can flow into the filter 10. First, the water can flow from the interior 160 through the filter housing 45 via the orifice 50 and through the filter cartridge 30. As the water travels through the filter cartridge 30, it is preferably at least partially cleaned of chemicals and particles. After passing through the filter cartridge 30, the water travels into the channel 40 and reaches the filter adapter 55. Finally, the water flows out of the bottle 5 via the bore 155 and the opening in the cap 20.

[0047] The venting of air facilitated by the umbrella valve 100 can allow the bottle 5 to provide a continuous flow of water as the user pours water from the bottle 5. Then, once the user has finished pouring water from the bottle 5, the force exerted by the air on the diaphragm 105 can drop below a threshold and the umbrella valve 100 can return to the closed position.

[0048] In one embodiment, when the air pressure within the filter 10 reaches or exceeds five kilopascals (kPa), the force applied by the air to the diaphragm 105 may exceed a threshold value and the umbrella valve 100 may open. In other embodiments, the umbrella valve 100 may open when the air pressure within the filter 10 is at or near 5 kPa. In other embodiments, the umbrella valve 100 may open when the air pressure within the filter 10 is within a defined range of values.

[0049] The threshold of force at which the umbrella valve 100 can be opened can be adjusted by changing the characteristics of the umbrella valve 100. For example, the flexural modulus of the diaphragm 105 can be changed by constructing the diaphragm 105 with a harder material or a softer material. A softer material can have a lower flexural modulus than a harder material, which in turn can lower the threshold. Alternatively, the threshold can be adjusted by changing the diameter of the diaphragm 105. As the diameter of the diaphragm 105 increases, the threshold can decrease. In some embodiments, the diameter of the diaphragm 105 can be no greater than the diameter of the cap 80.

[0050] Go to Figure 7 , the latch member 165 is attached to the outside surface 170 of the cover 20. The user can open the cover 20 by rotating the latch member 165 away from the surface 170. The latch member 165 can be attached to the cover 20 by screws 175 or other rotatable attachment mechanisms that will be understood by those skilled in the art.

[0051] The cover 20 may also have a handle 180. The handle 180 may be attached to the surface 170 of the cover 20 by screws 175 or other rotatable attachment mechanisms understood by those skilled in the art. The handle 180 may be U-shaped to allow a user to easily carry the bottle 5 from one place to another. As understood by those skilled in the art, the handle 180 may also be provided in the form of a ring or other similar shapes.

[0052] As will be apparent from the foregoing description, certain aspects of the present invention are not limited by the specific details of the examples shown herein, and it is therefore expected that other modifications, applications, variations, or their equivalents will occur to those skilled in the art. However, after considering the specification and the accompanying drawings, many such changes, modifications, variations, and other uses and applications of this construction will become apparent to those skilled in the art. In addition, unless otherwise indicated above, it should be noted that all figures in the accompanying drawings are not drawn to scale. All such changes, modifications, variations, and other uses in applications that do not depart from the spirit and scope of the present invention are considered to be covered by the present invention, which is limited only by the appended claims.
