Description: Container Cover and Dispensing Device This invention relates to a container cover and dispen ¬ sing device. More specifically, the invention relates to a bottle co- ver and dispensing device for use on a container for liquid under pressure such as a cola or other carbonated soft drink, In general, carbonated beverages are available in small glass or plastic bottles or in metal cans for immediate consumption, or in a variety of large glass or plastic bott- les. Larger bottles are intended to store some of the beve¬ rage after the bottle has been opened and some of the con¬ tents removed. Often the beverage remains in a previously- opened bottle for days at a time, and the carbonation of¬ ten dissipates leaving the drink "flat". Moreover, the me- re act of pouring a soft drink from a bottle /particularly by children/ can be awkward and messy. Accordingly, a need exists for a cover and dispensing device which facilitates dispensing of carbonated or other beverages under pressure, and which reduces the loss of pressure on already opened containers, i.e. containers from which some of the contents have been dispensed. An object of the present invention is to meet the above defined need by providing a relatively simple and inexpen¬ sive container cover and dispensing device, which makes it easy to dispense a liquid under pressure, without mo¬ ving the bottle containing the liquid. A second object of the invention is to provide a device which, once placed on the container remains in position and reduces the likelihood of loss of pressure until all of the liquid has been dispensed. Another object of the invention is to provide a device 5 which makes it difficult to dispense the liquid in a con¬ tainer unintentionally which is important in households with young children. Accordingly, the invention relates to a cover and dispen¬ sing device for use on a container of liquid under pressure o comprising cap means for mounting on the open top end of the container, said cap means including cylindrical side wall and circular top wall for mounting in sealing engage¬ ment on the open top end of the container; preferably sleeve means extending downwardly from said top wall, said 5 sleeve means having an open bottom end for receiving fluid from the container, an open top end for discharging fluid from the container and valve seat in said open top end; and valve means preferably in said sleeve means; said valve means including tubular- body fixed in said sleeve means; o head on said body normally sealing against said valve seat; plunger extending upwardly from said head through top wall; . and resilient cage defining a section of the valve body be¬ neath said head, whereby, when said plunger is pressed downwardly, the cage is deformed to move said head away 5 from valve seat permitting the discharge of fluid through cage and from the container, or the said valve means inclu¬ ding a resilient plate shape normally sealing against the valve seat and when the plunger is pressed downwardly, said plate shape is deformed moving away from the valve seat.

Wherever possible the same reference numerals have been used to identify the same or similar elements in the various figures of the drawings. In many cases, elements have been omitted from figures of the drawings to simplify illustration of the invention. In the following detailed description, the only container described for use with the device of the present invention is a plastic soft drink bottle. However, it will be appreciated that the device can be used on other containers for pressurized liquid. With reference to Figs. 1 to 5, the basic elements of a cover device in accordance with the present invention include a cap 1 for mounting in sealing engagement on the open top end of a bottle 3, a tube 4 extending between the bottom of the bottle 3 and the cap 1, and a valve body 5 (Figs. 4 to 6) mounted in the cap 1. p The cap 1 is defined by a circular, slightly concave top wall 7, and a cylindrical side wall 8 integral with the top wall 7 and extending downwardly therefrom. The cap 1 is retained on the bottle 3 by a thin, upwardly and inwardly inclined, annular skirt or flange 10 on the bottom end of the side wall 8. The flange 10 engages a shoulder 11 on the top end of the bottle 2. A seal between the cap 1 and the bottle 2 is achieved by means of an annular wall 13 parallel to and substantially shorter than the side wall 8. As best shown in Fig. 4, when the cap 1 is placed on a bottle 2 the top end of the bottle extends into an inverted V-shaped recess 14 between the wall 8 and the sleeve 13. Thus, a seal is achieved between the top end of the bottle 2 and the cap 1. A sleeve 15 (Fig. 4 and 5) extends downwardly around a central opening 16 in the top wall 7 of the cap 1. The sleeve 15 defines a valve casing for the valve body 5. As best shown in Fig. 6, the valve body 5 includes a tubular, cylindrical bottom section 18 which is retained in the sleeve 15 by friction. An annular flange 20 on the bottom end of the section 18 limits upward movement of the valve body 5 in the sleeve 15. The top end of the tube 4 extends into the bottom section 18 of the valve body 5 and abuts an annular, inwardly extending flange or shoulder 21 at the upper end of such bottom section. Three narrow, resilient arms 22 extend upwardly and inwardly from the upper end of the bottom section 18 and support a disc 23 of smaller diameter than the bottom section 18. The disc 23 normally rests against a shoulder 24 around the opening 16 (Figs. 4 and 5) in the top wall 7 of the cap which defines a valve seat. The valve body is formed of a material such as a rubber, which is sufficiently resilient and flexible that the arms 22 are relatively easy to bend and the disc 23 seals tightly against the shoulder 24. The disc 23 is moved away from the valve seat by a plunger 26 extending upwardly from the center of the disc 23 through the opening 16. The plunger 26 is smaller in diameter than the opening 16 so that fluid can escape through the opening when the valve is open. Fluid escaping through the opening 16 is discharged from the device via a downwardly inclined dispensing nozzle generally indicated at 28 integral with the cap 1. The nozzle 28 (Figs. 7, 15 and 18) includes a elongated, generally rectangular cross section body 30 defined by a top wall 31, a bottom wall 32 and side walls 33. The side walls 33 are generally V-shaped in cross section to facilitate flexing of the nozzle in the manner of an accordion. Small, generally U- shaped ridges 35 extend upwardly from the top wall 31 near the semicircular inner end thereof. The ridges 35 define finger grips for the user, i.e. prevent sliding of a fingertip from the top wall 31 when the device is being used. The valve is opened during a dispensing operation by pressing down on the top wall 31 against the plunger 26 to flex the arms 22 and thus move the disc 23 away from the. valve seat (shoulder 24). The liquid in the bottle 3 is propelled therefrom by its own pressure, i.e. by the carbonation pressure. In the first embodiment of the invention, the nozzle 28 is closed by a cover 36 when the device is not in use. The cover 36 not only closes the nozzle 28, but prevents an unauthorized or accidental dispensing operation, for example by a child. As best shown in Figs. 8 to 13, the cover 36 includes an elongated, rectangular body 38 with an open bottom end which is defined by a rectangular top wall 39, side walls 40 and an outer end wall 41. The end wall 41 is wider than the side walls 40 for closing the outer, discharge end 43 of the nozzle 28. A plurality of small ribs 44 extend transversely of the top and side walls of the cover 36 facilitating fingertip gripping and moving of the cover. The cover 36 is slidably mounted on the nozzle body 30 by means of a pair of slides defined by elongated arms 46 connected at one end to the interior surface 47 of the cover end wall 41. The arms 46 extend from the end wall 41 to a location beyond the other, open end 48 of the cover, so that, when the cover 36 is in the closed position (shown in solid lines in Fig. 4), the inner, free ends of the arms 46 bear against the upper, inner end of the top wall 31 of the nozzle 28. Thus, the arms 46 prevent downward movement of the top wall 31 and consequently of the plunger 26 and opening of the valve. The cover 36 is maintained on the nozzle 28 by a stop defined by a small transversely extending projection 52 (Figs. 4, 5, 7, 15 to 18) on the outer top end of the nozzle 28. In the closed position (Fig. 4) of the cover 36, the projection 52 rests in a small, straight groove 53 extending transversely of the inner surface 54 (Figs. 5 and 11 to 13) of the top wall 39 of the cover near the outer end wall 41. The projection 52 and the recess 53 act as a lock for releaεably latching the cover 36 in the closed position. By applying downward and outward pressure to ribs 44, the cover 36 is caused to move outwardly. When the cover 36 moves outwardly, the> projection 52 enters an elongated rectangular recess 56 in the inner surface 54 of the cover 36 for free sliding movement of the cover. The upper, inner end 57 of the recess 56 acts as a stop for limiting movement of the cover 36 to the open position (see Fig. 4 in phantom outline and Fig. 5 in solid lines). Square recesses 58 (Figs. 10 and 11) are provided at the sides of the top end of the surface 54 so that the cover 36 can pass over the ends of the ridges 35 when moving to the - lo - closed position. A second embodiment of the invention (Figs. 14 to 16) includes the same elements as described above in connection with Figs. 1 to 13, and a pair of arcuate walls 60 extending upwardly from opposite sides of the top wall 7 of the cap 1. The walls 60 define barriers which limit ready access to the nozzle 28 to locations immediately in front of and immediately behind the nozzle. This arrangement further reduces the likelihood of accidental or unauthorized opening of the valve, and as shown in Figs. 14 to 16, can be used without the cover 36. As shown in Fig. 14, the dispensing device can be used with a short tube or straw 61 on an accordion-type bottle 62, which incudes pleats 63 in the side wall 64 thereof, whereby the bottle collapses as the contents are discharged therefrom. With reference to Figs. 17 and 18, a third embodiment of the invention, which is similar to the first two embodiments, includes a thin, annular skirt 66 extending downwardly from the bottom end of the sidewall 8 of the cap, for sealing engagement with a neck of a bottle (not shown). The. skirt 66, which includes a plurality of V-shaped grooves 67 therein, replaces the flange 10 used in the first two embodiment of the invention. A cover and dispensing device in accordance with the present invention can also be used for downward dispensing of the contents of a bottle i which case the tube 4 can be omitted. As shown in Fig. 19, the bottle 3 can be mounted in an inverted position on an L-shaped stand 70 of the type including a bracket 71 for holding the bottle £ . The nozzle 73 of the cover and dispensing device is inclined downwardly (rather than upwardly) when the bottle and the device are in the inverted position. When a drinking glass 74 or other container for receiving some of the contents of the bottle 3 is pressed against an arcuate arm 76 of a resilient lever 77, the other arm 79 of the lever 77 rotates downwardly against one end 80 of a second lever 82. The lever 82 is pivotally mounted on a horizontal arm 83 of the stand 70 for rotation around a horizontal axis 84, whereby an outer free end 85 thereof presses upwardly against the top wall of the cap 1 to open the valve, initiating a dispensing operation. As long as pressure is applied to the bottom end of the lever 77, liquid will be dispensed from the bottle (of course, until the bottle is empty) . When the lever 77 is released by removal of the glass 74, the levers 77 and 82 return to the rest position, and the valve again closes, terminating the dispensing operation. With reference to Figs. 20 to 28, a fifth embodiment of the cover device of the present invention includes a cap 1 for-mounting on the top end of a bottle, a tube 4 (Figs. 20 and 21), a valve body 88, a plunger assembly 89 separate from the valve body 88, and a cover 90 slidable on the nozzle 28 of the cap 1 for closing the nozzle. Like the cap of Figs. 1 to 5, the cap 1 is defined by a circular top wall 92, and a cylindrical side wall 93 integral with the top wall 92 and extending downwardly therefrom. Threads 95 are provided on the interior of the side wall 93 for mounting the cover device on a plastic soft drink bottle. A seal between the cap 1 and the bottle is achieved by an annular wall 13 parallel to and substantially shorter than the side wall 93. As with the above described first embodiment of the invention, when the cap 1 is placed on a bottle, the top end of the bottle extends into an inverted V-shaped recess 14 between the wall 93 and the sleeve 13. A sleeve 97 extends downwardly around a central opening 98 in the top wall 92 of the cap 1. The sleeve 97 defines a valve casing for a valve body 88. As best shown in Figs. 20 and 22 to 25, the valve body 88 includes a tubular, cylindrical lower section 100, which is retained in the sleeve 97 by friction. A shoulder 101 in the sleeve 97 and an annular flange 102 extending outwardly from the middle of the lower section 100 limit movement of the valve body into the sleeve 97. The end 103 of the lower section 100 beneath the flange 102 has a thinner wall than the top end above the flange 102, so that the bottom end of the valve body can be rolled upwardly and inwardly for receiving the top end of the tube 4. Lugs 104 extend outwardly from the bottom end of the lower section, so that when the bottom end 103 is rolled up into the center of the lower section 100, the lugs 104 define stops for limiting movement of the tube into the valve body. Four narrow, resilient arms 106 extend upwardly and inwardly from the top end of the lower section 100 of the valve body 88 and support a generally button-shaped head 107. A small pointed projection 109 is provided on the bottom center of the head 107 for directing liquid outwardly from the top of the straw 4 through the gap between the arms 106. The head 107 is centered and guided by four longitudinally extending ribs 110 in the top end of the sleeve 97. A tube 112 extends downwardly from the center of a raised portion 113 of the top wall 92 of the cap through the opening 98 for slidably receiving the plunger 115 of the plunger assembly 89. The bottom ends of the tube 112 and of the plunger 115 are seated in a central recess 116 in the head 107 of the valve body 88. As shown in Fig. 21, the plunger 115 is longer than the sleeve 112 so that the top end of the plunger extends upwardly beyond the top end of the raised central portion 113 of the top wall 92. The plunger assembly 89 includes the plunger 115, a generally circular top plate 118 and a skirt 119 extending downwardly from all but one side of the top plate 118. One side 121 of the top plate 118 is inclined downwardly and extends outwardly over the top wall 31 of the nozzle 28. The inclined side 121 of the top wall 118 is parallel to and spaced apart from the top wall 31 of the nozzle 28, so that the plunger 115 can be moved downwardly to open the valve when pressure is exerted on the top wall 118. When the device is in use, the cover 90 (Fig. 21) is in an extended position so that liquid can be dispensed through the valve and the nozzle 28. Upon completion of a dispensing operation, the carbonation in the beverage returns the plunger assembly to the elevated, rest position. The cover 90 is slid upwardly on the nozzle 28, whereby the top wall 123 of the cover slides between that side 121 of the top wall 118 and the top wall 31 of the nozzle 28 to prevent downwardly movement of the plunger assembly 89. While the nozzle 28 shown in Fig.28 includes vertical partitions 125, it will be appreciate that such parti- tions can be omitted. The cover 9o is slidably mounted on the nozzle 28 in essentially the same manner as in the other embodiments of the invention. As shown in Fig.21. arras 46 are provided on the cover 3o for sliding in the nozzle 28. Movement of the cover 9o is controlled by a projection 52 and the recesses 53 and 56. A...rib"-126 extends transversely of the top of the cover 9o facili¬ tating fingertip movement of the cover. With reference to Figs.29 to 37, a sixth embodiment of the cover device of the present invention includes a cap 1 for mounting on the top end 2 of a bottle 3, a valve body 13o,/Fig.33 and 34/ a plunger 26 with a top plate 118 separate from the valve body 13o, where the top plate 118 is turnable to prevent the pressing of the plun¬ ger 26. The nozzle 28 leads into an annular groove 98 surrounding the central opening 16, similarly to the fifth embodiment/Fig.31/. The inner surface of the top wall 7 defines a valve seat 24 around the said groove 8 and sleeve 112 extends downwardly as the continuation of the opening 16, which sleeve 112 comprises the bottom end of the plunger 26. The valve body 13o has a central recess 116 containing the end of the sleeve 112 and the plunger 26. Around the central recess 116 a valve sur¬ face 131 seals against the annular groove 98 and the said valve seat 24, and an circular recess 133 sur¬ rounds them having an opening 135 in it to the opposi¬ te side of valve body 13o into downwardly extending sleeve 136 to retain the tube 4. The collar 132 of the valve body 13o covers the whole inner surface of the top wall 7 inside of the cylindrical side wall 8. On the top wall 31 of the nozzle 28 is projected an upwardly frame 144 to control the horizontal turning of the top plate 118 by a tongue 155 extending into said frame 144 and in the middle two stop means 142 and oppo¬ site with the frame 144 a deep-recess 141 with two half- recess 143 left and right side of it. On the bottom si¬ de of the top plate 118 are two lugs 154 and opposite with the tongue 155 an inwardly bulge 156. In the middle- position of the top plate 118 the lugs 154 are unhibited and the bulge 156 seats in the deep-recess 141, conse¬ quently the top plate 118 may press down for functioning the valve body 13o. Turning on the top plate 118 to left or right about angular 3o°, the lugs 154 are rested on the stop means 142 and the bulge 156 in one of the half- recess 143 hindering by them the pressing of the top pla¬ te 118 to prevent unauthorised operations. An further preferred embodiment is shown on the Fig.3o of the device of our invention provided with an press- arm l6o over the nozzle 28. The press-arm l6o replaces the top plate 118, is conjoined with a hook 165 to a loop 127 can find on the opposite side of the cap 1 to the nozzle 28. The said press-arm l6o is elongated to the discharge end 43 of the nozzle 28 and its outer clo¬ sing wall 162 closes the nozzle 28 to prevent liquiddrop Pressing down the press-arm 160 they operate the plunger 26 and open the valve for liquid-flow, simultaneously the closing wall 162 moves down and the opening l6l comes before the discharge end 43. The lower edge 166 of the closing wall extending below the nozzle 28 is keeping the press-arm I60 in the closed position. A preferred embodiment of the device of our invention in the inner side of the side wall 8 the inner thread is replaced with circular shoulder 17o with upwardly edge /Fig.37/, effected an without special tools non-relea- sable binding with the annular flange 11 of the outer side of the top end 2 of the bottle 3, accordingly to health hygenic inquires to prevent the unauthorised refilling of the container 3.
