2. Description of the Related Art
Personal beverage bottles are becoming ever more popular and have moved beyond the common beverage bottle packed with a school lunch or in a lunch box. Gyms are filled with members exercising, and many members bring their own beverage bottles for hydration. Hikers, bikers, walkers, commuters, tourists and many others carry beverage bottles as they go on their way. An increasingly common feature of the beverage bottles is a drink nozzle or spout that offers the ability to drink from the bottle without complete removal of the lid from the bottle. Another feature of some drink bottles is a cover for the drink spout or nozzle to keep the spout or nozzle clean between drinking.
The present invention provides a beverage bottle with a removable lid wherein the lid has an inner lid with a drink spout and an outer lid or cover that is hinged to selectively cover the drink spout. The outer lid may be locked to the inner lid when in the closed positioned. A push button on the inner lid can be operated to release the locked outer lid, permitting the outer lid to open so as to permit drinking from the drink spout. The push button is mounted on a pivot structure and connected on one side to one end of a lid slide. The other end of the lid slide extends to a portion on the inner lid opposite to the hinge and contains an extension that engages with a notch in the upper lid to hold the upper lid closed. On pressing on one side of the push button towards the radial center of the bottle, the other side of the push button moves away from the radial center of the bottle and pulls the lid slide with it. The extension located on the other end of the lid slide moves out of engagement of the outer lid, thereby opening the outer lid.
In one embodiment, a biasing element causes the lid to be moved into the fully open position. The biasing element may be made of a flexible, resilient material that, when deformed, moves back into its original position.
In another embodiment of the invention, the lid slide is biased by a biasing element so that the extension that holds the outer lid in the closed position protrudes into its engagement position except when pressure is placed on the push button.

Referring first to
The removable lid 14 is secured to the mouth of the bottle 12 by a threaded connection in the illustrated embodiment. Threads are formed about the mouth of the bottle 12 and cooperating threads are formed within the lid 14 so that the lid 14 may be threadably attached to and detached from the bottle 12. The bottle 12 may be a narrow-mouth bottle or a wide-mouth bottle; a wide-mouth bottle is shown. Other fastening means to attach the lid 14 to the bottle 12 may be provided instead, such as a snap-on lid that fits onto a rim on the bottle, a bayonet attachment, or other lid attachment structure.
The removable lid 14 has an inner lid 20, a push button 22, an outer lid 24 and a hinge 26 that connects the inner lid 20 to the outer lid 24. A handle 28 may be attached to inner lid 20 and/or outer lid 24 to provide a convenient method of carrying the bottle 10 or attaching the bottle 10 to a backpack, gym bag or the like. Outer lid 24 may be either in the closed position or open position. In the closed position, as shown in
The removable lid 14 is shown in the open position in
Drink spout 30 is mounted through pedestal 34. Pedestal 34 provides structural support for drink spout 30 and helps to keep drink spout 30 oriented in a direction away from hinge 26 and open outer lid 24 to make drinking from the drink spout 30 easier for the user. Pedestal 34 may contain vent hole 36 that provides a passageway to the interior of body bottle 12. When a user drinks through drink spout 30, the liquid in body bottle 12 is drawn through the internal straw and out from drinking tube 32. The removal of liquid from the bottle may cause a negative air pressure within the bottle, especially for rigid bottle configurations. By providing vent hole 36, the negative pressure within body bottle 12 is prevented by the inflow of air into the bottle through the vent, thereby making drinking from the bottle easier. The vent hole 36 in the pedestal 34 is closed by a vent pin 37 that extends from the interior of the outer lid 24. Closing of the vent hole 36 when the lid is closed helps prevent leaking of the liquid from the drink bottle, for example when the bottle is stored on its side such as when placed into a school locker or gym bag. When the outer lid 24 is opened, the vent pin 37 moves clear of the vent hole 36, permitting the flow of air into the interior of the bottle 10 when a user drinks from the spout 30. If the present lid is to be used on a flexible squeeze bottle in which the user squeezes the bottle to force the beverage from the drink spout, the vent hole and the vent closing pin may not be necessary.
The spout 30 is formed of a pliable material, such as silicon rubber that flexes and bends readily. When the outer lid 24 is moved to the closed position, a bending flange 38 extending from the inner surface of the outer lid presses on the spout 30 and bends it down from the upwardly angled position shown in
Outer lid 24 is kept in the closed position over inner lid 20 by the engagement of catch extension 42 that protrudes from an opening at a front of inner lid 20 with catch notch 44 located on circumferential lower edge 46 of outer lid 24. Catch extension 42 is moved out of engagement with catch notch 44 by actuating push button 20. After catch extension 42 is disengaged from catch notch 44, in one embodiment, outer lid 24 is biased into the fully open position at least in part by lid biasing element. The details of the lid biasing mechanism and lid release mechanism are described in more detail below.
As shown in
Middle cover 50 is sized with a diameter such that when middle cover 50 is inserted into upper cover 48 during manufacturing, the peripheral upper edge of middle cover 50 contacts the internal lower edge of ridge 54 to form a compartment between upper cover 48 and middle cover 50 that has catch extension opening 56 on one side and a push button opening (not shown in this view) directly opposite. Lower cover 52 has the same diameter configuration as middle cover 50. Pedestal 34 extends upward from the top of lower cover 52, and drinking tube 32 extends from pedestal 34.
On assembly, drinking tube 32 and pedestal 34 are inserted through spout opening extension 60 and upper cover 48, middle cover 50 and lower cover 52 are then connected together to form inner lid 20. The covers may be attached together in any known manner. Seals may be used to prevent liquids from passing between the covers that form inner lid 20. In an alternate embodiment, inner lid 20 may be formed from two covers. In such an alternate embodiment, the structures of middle cover 50 and lower cover 52 may be combined into one structure.
In one embodiment, when outer lid 24 is released from inner lid cover 20 by the actuation of push button 22 thereby causing disengagement of catch extension 42 from catch notch 44, outer lid 24 moves toward an open position in part by the biasing force of spout 30 acting on bending flange 38 as will be discussed below. Outer lid 24 is also moved toward a fully open position and may be automatically held in the fully open position by a lid biasing mechanism. Lid biasing element 47, shown in
In addition to the force exerted by lid biasing element 47, the drink spout 56 is in the crimped position as a result of being pressed by the bending flange 38 and against the counter ridge 72 when the cover is in the closed position. The resilient nature of the drink spout 56 and the material of which it is formed biases the outer lid 24 toward the open position as a result of the bending flange 38 pressing on the spout material. As a result, the spout provides a primary force for initial opening the outer lid 24 upon actuation of the release button 22. Further opening force to the fully open position is provided by the biasing element 47. The biasing element 47 may provide a primary force for moving outer lid 24 to the fully open position or the lid may be moved toward the fully open position by the user and retained there by the biasing element 47. The force of the biasing element 47 on the outer lid 24 is easily overcome by the user to move the outer lid 24 to the closed position.
The lid release mechanism is comprised of push button 22, lid slide 86 and slide biasing element 94. In one embodiment, push button 22 has a pivotal connection 76 that holds it within push button frame 74 by pin 78. Pivotal connection 76 sections push button 22 into upper end 80 and lower end 82 thereby allowing a rocking movement around the pivotal connection. Slide engagement extension 84 extends from upper end 80 of push button 22 and engages with button engagement extension 88 of lid slide 86. Lid slide 86 is located within the interior space between upper cover 48 and middle inner cover 50. The opposite end of lid slide 86 contains catch extension 42 that protrudes from catch extension opening 56. As shown in
On pushing lower end 82 of push button 22 towards the radial center of removable lid 14, upper end 80 moves radially outward. This motion pulls lid slide 86 in the direction towards a side of the lid with the push button 22 and causes catch extension 42 to be retracted into catch extension opening 56. Retracting catch extension 42 causes it to disengage from catch notch 44 of outer lid 24 thereby releasing outer lid 24 from the closed and latched position so that it may move into the open position. The retracted position of lid slide 86 with outer lid 24 in the open position is shown in
On releasing push button 22, slide biasing element 94 retracts from its stretched condition to cause lid slide 86 to move away from the side of the lid with the push button 22 and back into its original position. Thus, catch extension 42 can be moved out of engagement with catch notch 44, but is biased back into its original position through slide biasing element 94. In another embodiment, slide biasing element 94 may be connected between push button 22 and inner lid 20 within push frame 74. In such an embodiment, the biasing may be either through, for example, the expansion or compression of a spring or other resilient material.
To keep lid slide 86 in its proper position, middle inner cover 50 may contain frame 62 that provides a guide for the lower sides of lid slide 86. Lid slide 86 may also contain spout opening 90 to provide clearance for spout opening extension 60 and allow passage of drink spout 30 from the interior of the bottle through inner lid cover 20. While the illustrated embodiment shows a notch in the outer lid and an extension on the end of the lid slide, alternative embodiments may be used such reversing the locations of the notch and extension or use of other mechanical or magnetic locking mechanisms.
The outer lid 24, and inner lid 20 are of polypropylene in one embodiment, but may be made of any number of plastics such as PET, HDPE, LDPE or other polyesters. The release button 22 may be of polypropylene or another material. As noted above, the drink spout 56 and spring 96 are of silicone rubber. Other materials are of course possible and are encompassed within the scope of the present invention.
Thus, there has been shown and described a drink bottle having a removable lid that has a drinking spout and a lockable cover or outer lid over the drinking spout. Although other modifications and changes may be suggested by those skilled in the art, it is the intention of the inventor to embody within the patent warranted hereon all changes and modifications as reasonably and properly come within the scope of his contribution to the art.
