Description:
This invention relates to a bottle and more particularly, to an improved water bottle for use by racers, particularly bicycle racers and marathoners. 
     BACKGROUND OF THE INVENTION 
     In many sports activities, such as long distance bicycle racing, marathon running and the like, the participant is easily prone to exhaustion and other physical ailments due to rapid dehydration. As a consequence, racers have taken to carrying water bottles on their bikes or on their person from which to imbibe as the need occurs. The term water bottle encompasses not only water, but juices, nutrient mixtures and other liquids which racers and the like consume. 
     Such bottles are generally provide with caps that are easily openable, and with straws or syphon devices through which the user may obtain the liquid. The use of such rather complex arrangements is to maintain integrity of the bottle, thereby avoiding contamination of the contents and premature spillage. 
     While bottles of this type generally accomplish their intended purpose in a satisfactory manner, there still exists a need for further improved bottles of this type which are even more secure particularly during race conditions or carried with dry goods, papers, clothing, food, etc. 
     The foregoing, as well as other objects, will be readily apparent from the following disclosure. 
     BRIEF STATEMENT OF THE INVENTION 
     In accordance with the invention, there is provided a bottle which comprises a generally elongated, cylindrical body member having a countersunk end wall closing one end defining a trough around the internal periphery thereof. A cover assembly closes the body member at the end opposite the end wall. The cover assembly includes top and bottom circular members, a pair of semi-circular segment plates slidingly disposed between the top and bottom member in spaced relationship with respect to each other. The semi-circular peripheral edges of the segment plates are supported and rotatable in a groove extending around the internal wall of the body and are urged apart by spring means located between the segment plates. A syphon tube forming an integral part of the body member extends internally downward into the trough of the body. A uni-directional air valve allowing entry of atmospheric air into the body, but preventing spillage of liquid outwardly is also provided in the bottom member of the cover. Mounted above the bottom cover member and extending through the upper cover member is a rotatable disk provided with a sucking tube and a mist screen outlet. The disk is rotatable between a closed position in which the syphon tube with a vent opening is blocked and an open positione presenting either the sucking tube or mist outlet in line with the syphon tube. 
     Thus, drinking from the bottle or misting oneself with water may be easily made by simply rotating the disk to align the sucking tube or misting outlet with the syphon tube. On the other hand, the bottle is closed by rotating the disk so that the sucking tube and misting outlet are out of alignment with the syphon tube. The bottle may be drained and/or filled by removing the cover assembly, simply by squeezing the segment plates toward each other to disengage them from the groove and lift the entire cover assembly out of the cylindrical body. 
     Full details of the present invention are set forth in the following description and are illustrated in detail in the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to FIG. 1, the bottle according to the present invention, comprises a generally elongated cylindrical body 10 closed at one end 12 and open at its opposite end 14. The closed end 12 is formed with a countersunk wall sloping downwardly around its peripheral edge to form a trough 16. 
     The inner surface 18 of the bottle is molded (see FIGS. 4, 2, 5 and 7) to provide a peripheral groove 20 just below the open end 14 and an annular flange-like shelf or ledge 22 just below the groove 20. An elongated boss 24 (FIG. 6) extends integrally with the inner surface 18 from the shelf 22 to a point within the trough 16 of the closed end wall. The boss 24 is formed with an interior bore forming a syphoning tube 26 from one end of the bottle to the other. 
     The bottle is provided with a removable closure assembly generally shown by numeral 28. The closure assembly 28 comprises a circular bottom disk 30 having an outside diameter equal to the inside diameter of the bottle 10 at its open end 14 so that it can rest on the shelf 22 and fit snugly within the bottle. Radially inward from the edge of the bottom disk is a through hole 32 provided with a lip 33 arranged so that the hole 32 can be accurately aligned with the syphoning tube 26. Located inwardly of and radially in line with the hole 32, is a uni-directional, ball-type valve 34 adapted to allow air into the bottle but prevent liquid from escaping. 
     Slidably resting on the upper surface of the bottom disk 30 are a pair of congruent semi-circular segment plates 36, the outer peripheral edges of which are pointed to provide an arrow shaped edge 38 which fits into the annular groove 20 provided in the inner wall of the bottle. The segment plates 36 are urged apart by a compression spring 40 set in facing a diameter slot 42 formed in each segment plate. To hold the compression spring in place, the segment plates 36 may be provided with a centrally extending tongue 44 passing through the slots 42 into the center of the spring 40. Other means for forming the spring biasing means or for holding the spring 40 may also be devised. To prevent the segment plates 36 from buckling, a pair of T-shaped brackets 46 are provided. The stems of the T-shaped brackets are integral with top surface of the bottom disk 30 so that the lateral arms pass into small slots 36a found in the segments 36 to guide the segments as they slide. In this manner, the segment plates 36 may be moved toward each other (arrows A) releasing the peripheral arrow shaped edges 38 from their seat in the groove 20. To facilitate squeezing the segment plates 36, each is provided with an upstanding finger tab 48. 
     The closure assembly 28 is completed by providing a top circular disk 50 integral with a spherical shaped dome 52. The top disk 50 is provided with a pair of spaced slots 54 which fit over the T-shaped brackets 48, and a pair of oppositely located semi-circular cut-outs 56 arranged to fit about the finger grips 48. Lastly, a vertical cylindrical section 58 is integrally formed to pass through the dome 52 and the top disk 50 in direct alignment with the syphoning tube 26 and the valve 34. Thus, the top disk and dome can be accurately placed in this alignment since the slots 54 and the cut-outs 56 establish a fixed relationship between the closure assembly and the bottom disk 30. In addition, the top disk 50 rests on the compression spring 40, which urge the finger grips apart and therefore, acts to keep the spring 40 in place. 
     To retard and maintain the movable plates 36 between the top and bottom disks (30 and 50, respectively), when the top is removed from the body of the bottle, each of the disks are provided with a peripheral head or lip 30a and 50a on the opposing and contacting surfaces with the plates 30 respectively. The heads are held in opposition so that a narrow annular space between the lips 30a and 50a are formed allowing the arrow shaped edges 38 to protrude only so far as to be able to seat within the groove 20, but not so far as to slide out from between the top and bottom disks. It is also possible to position the finger grip 48 at a distance inwardly of the peripheral edge of the top disk 50 so that the top disk would hold the plates from sliding outwardly. 
     Set within the vertical cylindrical section 58 is a carousel 60 rotatable in either direction (see Arrow B). The carousel has a flat base 62 and a vertical upward peripheral wall 64 sealed with respect to the disk 30 against fluid flow. The flat base 62 is adapted to lie on the bottom disk 30 of the closure assembly to normally occlude syphon outlet 32 and the valve 34. The flat base 62 is provided with two holes in one of which is wedged in fixed arrangement, a sucking tube 66, and in the other is fit a small pore screen 68 designed to turn a stream of water into a mist. The two holes in base 62 are arranged so that when either one of the sucking tube or screen is located in axial alignment with syphoning outlet 32, the other is in axial alignment with the valve 34. Otherwise, both the syphoning tube and the valve are occluded and no liquid can be withdrawn or squeezed out of the bottle nor air allowed in. Preferably, the syphon hole 32 and valve 34 and the sucking tube 66 and screen 68 in the carousel are aligned respectively along a diameter of the bottle so that rotation between an inoperative and operative position is easily made. In addition, the external surface of the bottle can be provided with indicia visual and/or tactile to indicate the correct operative position of the carousel. The sucking tube 66 preferably is long enough to extend above the surface of the dome 52 so that the user can easily apply his mouth to it. The entire cover assembly is easily removed by squeezing the finger grips together releasing the segment 36 from engagement with the groove 38 carrying with it, the bottom disk 30 and the top disk 50 with the dome 52. Refilling and cleaning of the bottle is thus quite easy. 
     The various, movable and slidable parts are provided with suitable liquid seals such as O-rings, washers and the like to make the bottle extremely safe during use. 
     The bottle and the parts thereof, are preferably made of strong, lightweight plastic, such as polyethylene, polyurethane, polyamide or polyester plastic which is readily available and inexpensive. On the other hand, it may also be made of metal such as lightweight steel, aluminum or tin. In this connection, the body may be made of metal and the cover of plastic, or the body of plastic and the cover of metal or any combination of plastic and metal. 
     The bottle may also be made in any of a wide variety of sizes and the interior surface of this bottle may be coated with a suitable coating material such as that known in the art to avoid any ill effects to the contents. The bottle may be employed to hold any suitable liquids such as coffee, tea, milk, water, juice, soda and the like. 
     Numerous modifications of the bottle of this invention may be made without departing from the spirit and scope of the invention. It is to be understood, therefore, that this invention is not to be limited to the embodiments described above, except as defined in the appended claims.
