This application claims priority to U.S. Non-Provisional patent application Ser. No. 10/860,203 filed on Jun. 3, 2004 and U.S. Non-Provisional patent application Ser. No. 11/076,143 filed on Mar. 9, 2003, which are incorporated herein by reference.
The present invention relates to the field of drinking bottles and, more particularly, to a vented, no-spill drinking bottle and bottle cap that solve the problems of spillage and vacuum formation when drinking from the bottle. The invention also relates to a refillable bottle and pouch system using a vented, no-spill drinking bottle.
Having a vacuum form in a drinking bottle, as occurs with presently available sports bottles, makes drinking from the bottle somewhat difficult. This problem is exacerbated in rigid bottles, such as glass bottles. Spillage is also a problem with many conventional drinking vessels.
Existing products configured prevent spillage and vacuum formation, such as the “sippy cup” familiar to moms and dads, use a two-port removable diaphragm to balance pressure within the container and prevent spillage through the diaphragm. This approach is somewhat complex to manufacture, and also presents problems with cleaning and often losing the removable diaphragm. In addition, this technology is not well suited for use with a standard sports bottle. As a result, a need exists for a no-spill, vented drinking bottle suitable for use as a sports bottle. There is a further need for a device for retrofitting a standard drinking bottle as a no-spill, vented drinking bottle. In addition, drinking bottles with regulated and adjustable flow rates are not presently unavailable.
The present invention solves the problems described through a vented bottles and bottle caps that typically includes two one-way valves. The first one-way valve vents the bottle while fluid exits the bottle, and the second one-way valve prevents spillage. A first embodiment of the vented bottle cap is configured for use with a conventional sports bottle, a second embodiment is configured for use with a conventional soft drink or water bottle, and a third embodiment includes a drinking bottle with a vent near the bottom of the bottle. The vented bottle cap may also be used in conjunction with a pouch system that allows a user to fill a pouch with fluid while the pouch is securely supported within the bottle. In this manner, a user can carry pouches, such as foil or plastic pouches, with desired ingredients, such as a water purifying chemical, a flavor ingredient, electrolytes, medicines and so forth. A pump may be used to deliver water from a water supply into the pouch while the pouch is supported within the bottle.
More generally described, the invention may be implemented as a drinking bottle or a bottle cap for a drinking bottle. The bottle cap includes a cap body that is configured for attachment to the bottle portion of the drinking bottle. The bottle cap also includes a drinking conduit through the cap body, and a first one-way vent located in the cap body for allowing air to enter the drinking bottle while fluid exits the bottle. The bottle cap may also include a second one-way valve located in the drinking conduit to prevent spillage of the fluid through the drinking conduit. For example, the bottle cap may be configured as a pull-up type bottle cap or as a flip-top bottle cap.
The invention may also be practiced as a drinking bottle including a bottle portion, a lid configured for attachment to the bottle portion, and a drinking conduit through the lid. The drinking bottle also includes a first one-way valve located in the lid or bottle portion for allowing air to enter the drinking bottle while fluid exits the drinking conduit under the force of gravity at a desired fluid flow rate. In addition, the first one-way valve may be adjustable to produce the desired fluid flow rate. The drinking bottle may also include a second one-way valve located in the drinking conduit to prevent spillage of fluid inside the drinking bottle through the drinking conduit. In a particular embodiment, the lid is configured as a funnel.
The invention may also be practiced as a drinking bottle and pouch system. The system includes a drinking bottle and a bottle cap that includes a drinking conduit. The bottle cap may be attached to the bottle portion of the drinking bottle and includes a straw that is configured to be placed in communication with the drinking conduit and extending from the underside of the bottle cap. The system also includes a pouch that has a pouch enclosure; one or more elongated wings, and a straw receptacle. The pouch is configured to be supported within the drinking bottle with the wings supported between the bottle portion of the drinking bottle and the bottle cap with the straw extending through the straw receptacle into the pouch.
In addition, the bottle cap typically includes a bottle attachment member that is removably attachable to the drinking bottle and a drinking member that is removably attachable to the bottle attachment member. The bottle attachment member is configured, when the drinking member is removed from the bottle attachment member, to receive a supply tube for delivering a fluid into the pouch while the pouch is supported within the drinking bottle. And the drinking member is configured to be attached to the bottle attachment member after the pouch has been filled with fluid. The bottle cap also typically includes a first one-way valve located in the cap body for allowing air to enter the drinking bottle while fluid exits the bottle, and a second one-way valve located in the drinking conduit to prevent spillage of the fluid through the drinking conduit. The system may also include a pump for delivering a fluid from a fluid supply into the pouch by way of the supply tube.
The specific techniques and structures for implementing particular embodiments of the vented bottle cap and associated pouch system, and thereby accomplishing the advantages described above, will become apparent from the following detailed description of the embodiments and the appended drawings and claims.
Turning now to the figures, in which like numerals refer to like elements throughout the several figures,
To implement the vented feature of the drinking bottle 10, the bottle attachment member 18 includes a first one-way valve 20 that allows air to enter the drinking bottle as fluid exits the bottle. This prevents a vacuum from forming inside the bottle while a user drinks from the bottle. In addition, to implement the no-spill feature of the drinking bottle, the drinking member 16 may also include a second one-way valve 22 in the drinking conduit to prevent spillage of fluid through the drinking conduit.
The pouch 60 may be a foil, plastic or any other suitable type of pouch. In addition, any suitable type of mechanism may be used to support the pouch with in the drinking bottle. The pouch may carry any type of desired ingredient 62, such a water purifying chemical, a flavor ingredient, electrolytes, medicines and so forth. In a preferred embodiment, for example, the pouch 60 includes a pouch body 64, two wings 66 a and 66 b that extend from the pouch body, and a rigid support for a straw opening 70. The bottle attachment member 53 includes a short straw 57 that is in communication with the drinking conduit, and which extends downward. The pouch is inserted into the bottle portion 58 with the wings extending out the top of the bottle portion and held taught while the bottle attachment member 53 is screwed or snapped onto the bottle portion 58. This holds the pouch 60 firmly in place with the straw 74 extending through the pouch straw opening 70.
The bottle attachment member 53 also includes a supply tube receptacle 56 which allows the user to connect a supply tube 54 a to the bottle attachment member for filling the pouch 60 with a fluid, typically water. As shown in
To prevent spillage, the vented drinking vessel may also include a check valve 126 associated with the curved straw 118 and/or a one-way valve 128 associated with the vent tube 120.
Alternatively or additionally, the vessel 110 may include a one-way valve 128, such as a silicon or other suitable type of duck-bill valve, in communication with the interior of the vessel.
If the one-way valve 128 is located in the vent opening 114, the vent tube 120 may be replaced by a solid handle including a port adjacent to and in communication with the vent opening 114. Further, for the embodiment with a one-way valve 128 in the vent opening 114, the vent opening and one-way valve need not be associated with the handle, and could be located anywhere in communication with the interior of the container 112. For example, the vent opening 114 and one-way valve 128 could be located in the bottom of the container 112, side of the container, or in the funnel shaped cap 116.
It should also be appreciated that selecting an inlet valve 128 with a desired flow rate or providing an adjustable inlet valve will regulate the air flow rate through the valve and thus control the rate of fluid flow through the bottle under the force of gravity. This will allow the vent system to be customized for various applications. In particular, the inlet valve may be selected or set to regulate the fluid flow rate through the bottle at a level that cannot be harmful to a person drinking from the bottle. The inlet valve may also be adjustable with settings appropriate for children and adults. An engineer skilled in the art of bottle design will be readily able to select the proper type of valve and air flow rate for a desired application.
In addition, the vented and no-spill drinking bottle may be implemented as a bottle cap that can be used with existing conventional sports bottles and other bottles. In addition, the drinking bottle and associated pouch system provides many advantages for joggers, bikers, hikers, campers, hunters and everyday drinkers of fluids. The pouch system also provides an innovative way for drink suppliers to offer products through pouches containing dry ingredients, or a small amount of concentrated liquid ingredients, without incurring the cost of shipping the fluid. Hikers, campers and hunters will certainly appreciate not having to pack the bulk of the fluid for their drinks. It should also be appreciated that the vented drinking bottle and pouch system provides a convenient way to administer medicine to a sick child or an injured individual, sugar to a diabetic “gone low.” The vented drinking bottle can also be used to expel a stream of fluid by squeezing the bottle, for example to irrigate and sterilize a wound, clean a contact lens, provide a drink to a dog, and so forth. Many other uses of the bottle and pouch system will become apparent as the technology is used in the community.
With respect to the one-way valves used in the bottle caps for the sports bottles described above, it has been found that a silicon duck-bill valve with a flange and indentation for holding the valve in place works well in these applications. For the soda bottle cap embodiment, flat slitted diaphragm valves are presently considered to be the best alternative. However, other types of suitable one-way valves may be used. It should also be appreciated that locating the one-way valve for the air vent in the bottle portion of the container is functionally equivalent to locating it within the bottle cap. Other variations of the basic designs shown in the preferred embodiments will become apparent to those skilled in the art of bottle design.
In view of the foregoing, it will be appreciated that present invention provides significant improvements in drinking bottles and, more particularly, in a vented, no-spill cap for a sports bottle and an associated pouch system. It should be understood that the foregoing relates only to the exemplary embodiments of the present invention, and that numerous changes may be made to these examples without departing from the spirit and scope of the invention as defined by the following claims.
