FIELD OF INVENTION

[001] The present disclosure generally relates to underwater drinking apparatus and more particularly to a container for a potable liquid, for safe use underwater.

BACKGROUND

[002] We all know the importance of water for human beings. A human being requires that an adequate amount of water to be maintained in the body. The loss of water from the body or an inadequate supply of water leads to dehydration, which in turn is critical for health. The human body needs water, no matter in what habitation the human resides or travels either on land or under the surface, for example, working in a mine, or diving underwater, and the like.

[003] Over the past few years, the sport of diving has become popular. Diving is a sport performed by an individual, by descending below the water’ s surface or, exploring under water, which results exposing of the individual to a high ambient pressure prevailing underwater. Diving may be performed by several classes of individuals (for example, recreational divers, technical divers, professional divers, public safety divers, military divers, and the like) for the purpose of interacting with the environment, and may dive up to a certain depth under the water. Due to diving, the environment prevailing underwater exposes the divers to a wide range of challenges, for example, breathing problem, drinking of water, transferring an attached article on back to another diver, and the like.

[004] Of the above mentioned challenges, drinking water underwater is a major challenge faced by divers, owing to the fact of high ambient pressure prevailing underwater. As we all know, human beings are not physiologically and anatomically well adapted to diving.

[005] Several underwater drinking apparatuses or containers are available, and are being used by the divers for drinking water. However, the existing drinking apparatus have one or more limitations that impose a restriction on the divers to drink water while diving. With the existing apparatuses, divers are unable to share the drinking bottle with another diver, as the bottle is fixed to a regulator which is fixed to a side or back of the diver.

[006] Further, some of the other existing drinking apparatuses include an open bladder. The open bladder is subject to ambient pressure that squeezes the flow end of the apparatus and thus restricts the flow of the liquid in it. Also, the existing apparatuses are made up with soft and flexible materials which can be damaged easily. In addition, due to the absence of an inner straw or tube in the existing drinking apparatuses, divers need to tilt the bottle upside down or the bottle needs to be squeezed manually, to push the liquid to a regulator to get a proper flow of the liquid.

[007] Further, some of the existing drinking apparatuses are difficult to clean or maintain.

For instance, it is difficult to maintain cleanliness, detecting any inner damage to the apparatus, and the like. Furthermore, some of the existing underwater drinking apparatuses allow the liquid to flow inward as well as outward from the bottle, while the diver is drinking the liquid.

[0025] In addition to the illustrative aspects, exemplary embodiments, and features described above, further aspects, exemplary embodiments of the present disclosure will become apparent by reference to the drawings and the following detailed description.

[0026] In one embodiment of the present disclosure, a container for a potable liquid for safe use underwater is provided. The container as disclosed allows a diver to drink a liquid underwater. The container includes a first chamber for storing air at a predetermined depth- pressure-air-volume-density and a second chamber for storing the potable liquid. The second chamber is positioned inside the first chamber through a detachable screw cap. The second chamber is fitted to one face of the detachable screw cap through an adapter. The detachable screw cap of the first chamber also includes an inlet valve, an air pressure gauge and a safety valve. Further, the container includes a tube, the tube having a first end and a second end. The first end of the tube is disposed inside the second chamber and the second end is disposed outside the first chamber. The first end of the tube is fitted with a one-way valve for preventing backflow of the liquid and the second end of the tube is fitted with a bite valve for controlling a flow of the liquid through the tube. In addition, the container includes a non-return valve for allowing the air at the predetermined pressure to flow from the first chamber into the second chamber.

[0027] FIG. 1 illustrates a container 100 for safe use underwater, according to an embodiment of the present disclosure. The container 100 includes a first chamber 102, a detachable deadweight 112 clamped to an end of the first chamber 102, a detachable screw cap 104, an inlet valve 106, an air pressure gauge 108, a safety valve 110, a carabiner slot 124, a second chamber 114, an adapter 126, a needle valve 122, a control knob 122-A of the needle valve 122, a tube 116, a check valve 118, an adjustable pinch valve 120, a tube ball valve 128 and a bite valve 130.

[0028] The container 100 for enabling a diver to drink a liquid, underwater is disclosed. In one embodiment, the container 100 includes the first chamber 102 and the second chamber 114. The second chamber 114 is positioned inside the first chamber 102 through the detachable screw cap 104. Also, a first end 115 of the tube 116 is disposed inside the second chamber 114 and a second end 117 of the tube 116 is disposed outside the first chamber 102.

[0029] The inlet valve 106, the air pressure gauge 108 and the safety valve 110 are disposed on the first chamber 102 through the detachable screw cap 104. The inlet valve 106 is configured for filling air in the first chamber 102 at a predetermined pressure. The air is filled in the first chamber 102 through a compressor or a hand air pump. The inlet valve 106 of the detachable screw cap 104 is at least one of a non-return valve or a one way valve. The non- return valve enables locking of air inside the first chamber 102 in form of a compressed air. The air in the first chamber 102 may be at a pressure of 2,000 to 10,000 mbar. In addition, the air pressure gauge 108 is configured for measuring the air pressure present inside the first chamber 102. In one example, while filling the air in the first chamber 102, in case the air pressure crosses a pre-determined threshold level, the safety valve 110 is configured for automatically releasing the air pressure using a spring action, for avoiding bursting of the container 100. [0030] Furthermore, the first chamber 102 is formed using at least one of several marine grade materials. The use of the marine grade material prohibits damage of the container 100 underwater. The outer surface of the first chamber 102 is coated with a luminous phosphorescent paint. The luminous phosphorescent paint facilitates visibility and thermal protection of the container 100, underwater. [0031] In addition, the end of the first chamber 102 is clamped to the detachable deadweight

112. The detachable deadweight 112 may include a plurality of spherical shaped balls, made of lead. Lead is used because of its high density. The detachable deadweight 112, when detached from the first chamber 102 provides buoyancy to the container 100 and if released, raises to the surface of the water and acts as a marker buoy. [0032] The needle valve 122 is assembled such that a control knob 122-A of the needle valve 122 is disposed on a second face of the detachable screw cap 104. In addition, the needle valve 122 is assembled such that an inlet nozzle 122-B of the needle valve 122 is positioned inside the first chamber 102 and an outlet nozzle 122-C of the needle valve 122 is positioned inside the second chamber 114. [0033] Now, referring to the second chamber 114 of the container 100, the second chamber

114 is configured for storing the potable liquid. The second chamber 114 is positioned inside the first chamber 102 through the detachable screw cap 104. The second chamber 114 is fitted to one face of the detachable screw cap 104 through the adapter 126. In other words, the second chamber 114 is positioned inside the first chamber 102 through the detachable screw cap 104.

[0034] As described above, the second chamber 114 includes the tube 116, the tube 116 being used by the diver for drinking the liquid. Further, the tube 116 has the first end 115 and the second end 117. The first end 115 of the tube 116 is disposed inside the second chamber 114 and the second end 117 of the tube 116 is disposed outside the first chamber 102. The first end 115 of the tube 116 is fitted with the check valve (one-way valve) 118 for preventing backflow of the liquid and the second end 117 of the tube 116 is fitted with the bite valve 130 for controlling the flow of the liquid through the tube 116. Also, the second chamber 114 includes the outlet nozzle 122-C of the needle valve 122, as described above.

[0035] The needle valve 122 allows flow of air from the first chamber 102 (for example, through the inlet nozzle 122-B) into the second chamber 114 (for example, through the outlet nozzle 122-C) in a single direction to increase the pressure in the second chamber 114 to enable the liquid to flow through the tube 116, when used underwater where the ambient pressure is higher as compared to the pressure above the water. The needle valve 122 is positioned such that the control knob 122-A of the needle valve 122 is disposed on the second face of the detachable screw cap 104 as shown in FIG. 1. The needle valve 122 is positioned such that the inlet nozzle 122-B is positioned inside the first chamber 102 and the outlet nozzle 122-C is positioned inside the second chamber 114. Further, the needle valve 122 is assembled such that the inlet nozzle 122-B is positioned inside the first chamber 102 is configured for allowing flow of air from the first chamber 102 into the second chamber 114. Further, the outlet nozzle 122-C of the needle valve 122 is disposed inside the second chamber 114 and is configured for allowing the flow of the liquid under pressure to enable the liquid to flow through the tube 116. [0036] In another embodiment of the present disclosure, an umbrella valve is used for allowing the flow of air from the first chamber 102 into the second chamber 114 in a single direction to enable the liquid to flow through the tube 116, as described above.

[0037] Further, in continuation with the description of the embodiment of the present disclosure, a plurality of flow control valves are arranged along the length of the tube 116, configured for controlling the flow of liquid. The plurality of flow control valves, for example, include the check valve (one-way valve) 118, the adjustable pinch valve 120, the tube ball valve 128 and the bite valve 130.

[0038] In the same embodiment, the check valve (one-way valve) 118 provided at the first end 115 of the tube 116 prevent the backflow of the liquid. In addition, the adjustable pinch valve 120 is fitted along the length of the tube 116 for pre-adjustment of a depth-pressure-air- volume-density for enabling the diver to pre-set the flow of the liquid. As soon as the control knob 122- A of the needle valve 122 is opened, the air flows from the first chamber 102 into the second chamber 114. As a consequence, the pressure inside the second chamber 114 increases, thus creating a pressure on the liquid in the second chamber 114. To control the pressure on the flow of liquid, out of the tube 116, the adjustable pinch valve 120 is designed such that the pressure required for the liquid to flow can be decreased thus, maintaining a proper flow of the liquid through the tube 116 in a controlled manner.

[0039] In another embodiment of the present disclosure, an umbrella valve (not shown in FIG. 1) can also be used instead of the needle valve 122. The umbrella valve is configured for providing a flow of air from the first chamber 102 into the second chamber 114. As a consequence of the flow of air from the first chamber 102 into the second chamber 114, a pressure is created, for enabling the liquid to flow out, through the tube 116. To control the pressure, on the flow of liquid, through the tube 116, the adjustable pinch valve 120 is used, such that the pressure on the flow of liquid can be decreased thus, maintaining the liquid to flow through the tube 116 in a controlled manner. The use of valves as described herein and the mechanisms explained enables the diver for easy drinking of liquid underwater.

[0040] Further, in the same embodiment, the second end 117 of the tube 116 is disposed outside the first chamber 102, is fitted with the bite valve 130. The bite valve 130 is configured for controlling the flow of the liquid through the tube 116. The bite valve 130, when pulled up, allows the liquid to flow through the tube 116. The bite valve 130, when pushed-down, stops the flow of the liquid through the tube 116.

[0041] Further, in another embodiment of the present disclosure, the second end 117 of the tube 116 disposed outside the first chamber 102, includes the tube ball valve 128. The tube ball valve 128 in turn is connected with the bite valve 130 for allowing the liquid to flow through the tube 116 and is regulated by a knob (not shown). The knob is configured to control the flow of liquid through the tube 116. [0042] In yet another embodiment of the present disclosure, the portion of the tube 116 disposed outside the first chamber 102 may be of different lengths. For example, the container 100 may have one or more different lengths of the tubes 116. The length of the tube 116 may depend on the type of the diving performed by the diver. For example, the length of the tube 116 with selected for various diving sports such as helmet diving, scuba diving, underwater walking, and the like. For various diving sports, the divers need tubes 116 of varying lengths for drinking the liquid, underwater. The lengths of the tubes 116 for the above mentioned type of diving can be customized as per the requirement of the users.

[0043] Further, the second chamber 114 may be formed using at least one of a material comprising a plastic or a marine grade material or combinations thereof. The use of plastic or the marine grade material prevents damage of the container 100 underwater. It may also be possible to equip the second chamber 114 with a scale for reading the liquid level. The carabiner slot 124 is provided for holding the container 100.

[0044] FIG. 2 illustrate a plurality of O-rings, coupled to the mouth opening of the first chamber 202 ( as referred as 102 in FIG. 1) of the container 100, respectively, according to an example embodiment of the present disclosure.

Now, referring to the FIG. 2, the detachable screw cap 204 (as referred as 204 in FIG. 1) and the first chamber 202 are provided with matching threads as shown, such that the screw cap 204 can be fitted securely to the first chamber 202. Further, one or more O rings 234 may be used along with the threads 232, in a known way, to make the chamber airtight to reduce leakage. The mouth opening of the first chamber 202 is wide, thus enabling easy maintenance of the first chamber 202. Also, the wide mouth opening provides easy access for cleaning and in inspecting the plurality of parts of the container (100, referring to FIG.l). By regular inspection and maintenance of the parts of the container 100 assists in the safe use of the container 100 for the divers. In addition, the regular inspection and maintenance of parts of the container 100 also increases the life of the container 100. As the container 100 is meant for use used by both professional divers and non-professional divers, the wide mouth opening of the first chamber 202 enables easy maintenance by the non-professional diver as well.

[0045] FIG. 3 illustrates an exploded view of an inlet valve 306 disposed outside of the detachable screw cap, according to an example embodiment of the present disclosure. As already discussed, the inlet valve 306, is a non-return valve or a one-way valve. The non-return valve or the one-way valve permits the flow of air in the first chamber (102, as shown in FIG. 1) in a single direction only. Further, the inlet valve 306 (106, as shown in FIG.l) stores air inside the first chamber 102 at a predefined pressure. The pressure of the compressed air in the first chamber 102 is in a range of an approximately 2000 mbar 10,000 mbar, for example. [0046] FIG. 4A and FIG. 4B show exemplary illustrations of a bite valve 430 (130 of FIG.

1) and a tube ball valve 428 (128 of FIG. 1) provided at a second end (117 of FIG. 1) of a tube (115 of FIG. 1) of the container (100 of FIG. 1), according to an exemplary embodiment of the present disclosure.

[0047] As already mentioned, the second end 117 of the tube 116is disposed outside the first chamber (102, as shown in FIG. 1). In one embodiment, the bite valve 430 acts a mouthpiece which offers the diver to drink the liquid from the container 100 without the use of hands. In addition, the bite valve 430 is also configured for automatic sealing of the container 100 after each sip and thus eliminating the escape of the liquid. The bite valve 430, when pulled- up, allows the liquid to flow in a single direction. The bite valve 430, when pushed-down, stops the flow of the liquid.

[0048] In another embodiment, the tube ball valve 428 may also be used instead of the bite valve 430 that acts as a flow lock on the second end 117 of the tube 116. The tube ball valve 428 may be used for pressure above 2,000 mbar.

[0049] FIG. 5A, FIG. 5B, FIG. 5C, and FIG. 5D show exemplary illustrations of an umbrella valve 536 (136 of FIG. 1), a needle valve 522 (122 of FIG. 1), an adjustable pinch valve 520 (120 of FIG. 1), and a one way valve 518 (118 of FIG. 1), according to an embodiment of the present disclosure.

[0050] As described above, the umbrella valve 536 is used for allowing the flow of air from the first chamber (102, as shown in FIG. 1) into the second chamber (114, as shown in FIG. 1) in a single direction through the tube (116, as shown in FIG. 1). Similarly, the needle valve

522 also allows flow of air from the first chamber 102 into the second chamber 114 in a single direction. The needle valve 522 is disposed such that the inlet nozzle (122-B, as shown in FIG. 1) is positioned inside the first chamber (102, as shown in FIG. 1) and the outlet nozzle (122- C, as shown in FIG. 1) is positioned inside the second chamber 114Further, the needle valve 522 is disposed such that the inlet nozzle (122-B, as shown in FIG. 1) is positioned inside the first chamber 102) and is configured for allowing flow of air from the first chamber 102into the second chamber 114Further, the second chamber 114 provided with the outlet nozzle (122- C, as shown in FIG. 1) of the needle valve 522 is configured for allowing the flow of the liquid in a single direction to enable the liquid to flow through the tube (116, as shown in FIG. 1). Also, the container (100, referring to FIG. 1) is provided with an adjustable pinch valve 520, fitted at a position along the length of the tube 116for pre-adjustment of a depth-pressure-air- volume-density for enabling the diver to preset the flow of the liquid, the liquid to flow through the tube 116when used underwater. The one-way valve 518 described herein, is provided at the first end 115 of the tube 116and prevents the backflow of the liquid, thus allowing the liquid to flow in a single direction only. [0051] The paragraph below illustrates an exemplary method for enabling a diver to drink liquid underwater, from the container (100, referring to FIG. 1). Consider an example where a diver is interested in diving. While diving, the diver may need to drink from the container 100. With the present embodiment of the disclosure, the diver has to pull-up the bite valve 130. The bite valve 130 when pulled up allows a liquid to flow through the tube 116). It may be noted that, the bite valve 130 is provided at a second end 117of the tube 116.

[0052] In addition, a control knob (122-A, as shown in FIG. 1) of the needle valve (122, as shown in FIG. 1) is opened for allowing a flow of air from the first chamber (102, as shown in FIG. 1) into the second chamber (114, as shown in FIG. 1). Further, the flow of air from the first chamber 102 into the second chamber 114 enables the liquid to flow in a single direction through the tube 116. It may be noted that the needle valve 122 is assembled such that the control knob 122-A of the needle valve 122 is disposed outside of the detachable screw cap (104, as shown in FIG. 1). The needle valve 122 is assembled such that the inlet nozzle (122-

B, as shown in FIG. 1) is positioned inside the first chamber 102 and the outlet nozzle (122-

C, as shown in FIG. 1) is positioned inside the second chamber 114 (for example, the outlet nozzle 122-C is attached to the top portion of the second chamber 114). Further, the needle valve 122 is assembled such that the inlet nozzle 122-B is positioned inside the first chamber 102 and is configured for allowing flow of air from the first chamber 102 into the second chamber 114. Further, the second chamber 114 is provided with the outlet nozzle (122-C, as shown in FIG. 1) of the needle valve, configured for flowing of the liquid in a single direction to enable the liquid to flow through the tube (116, as shown in FIG. 1).

[0053] For stopping the liquid flowing through the tube 116, the diver has to push the bite valve 130 down. Also, the diver has to close the control knob 122-A of the needle valve 122 for stopping the flowing of air from the first chamber 102 into the second chamber 114. The needle valve 122 is closed by turning the control knob 122-A of the needle valve 122 to OFF position. On turning the control knob 122-A of the needle valve 122 to OFF position, the flow of air from the first chamber 102 into the second chamber 114 is stopped. [0054] It is to be noted that, the implementation of the present disclosure is not only limited to professional divers as disclosed herein, but can be used by the non-professional diver, underwater helmet walker, also wherever needed.

[0055] Also, it is to be noted that, the practice of the present disclosure is not limited only to underwater applications as described herein, but can also be used above the surface of water, for drinking a liquid. The container (100, referring to FIG. 1) for a potable liquid can also be used for drinking the potable liquid, while travelling in a bus, driving a car, by a physically challenged person, by a fireman while extinguishing the fire break out, and the like. The use of the container for the potable liquid, above the surface of water, is explained in detail in below paragraphs. [0056] In yet another embodiment of the present disclosure, a container 100 for a potable liquid is disclosed. The container 100 allows a user to drink liquid, above the surface of water without tilting the container, without much effort and without spilling the liquid. Or, in another words, the user does not need to tilt the container for drinking the liquid and can drink with less suction. The container includes a first chamber (102, as shown in FIG. 1) for storing air at a predetermined pressure and a second chamber (114, as shown in FIG. 1) for storing the potable liquid. The second chamber 114 is positioned inside the first chamber 102. In addition, the container includes a tube (116, as shown in FIG. 1) having a first end (115, as shown in FIG. 1) disposed inside the second chamber 114 and a second end (117, as shown in FIG. 1) disposed outside the first chamber 102. The first end 115of the tube is fitted with a one-way valve for preventing backflow of the liquid and the second end 117 of the tube 116 is fitted with the bite-valve (130, as shown in FIG. 1) for controlling a flow of liquid through the tube. Further, the container 100 includes a non-retum valve for allowing flow of air from the first chamber 102 into the second chamber 114.

[0057] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.

[0058] The figures and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, orders of processes described herein may be changed and are not limited to the manner described herein. Further, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts necessarily need to be performed. Also, those acts that are not dependent on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples. Numerous variations, whether explicitly given in the specification or not, such as differences in structure, dimension, and use of material, are possible. The scope of embodiments is at least as broad as given by the following claims.
