Some of these patents are designed to work only with wide mouth containers. Others of these devices employ complicated pumping devices that would be expensive to manufacture and prone to damage or leakage. For example, the Patnaude U.S. Pat. No. 3,602,387 employs a bellows with an internal spring. The spring would be an expensive part to install inside of a bellows. Further, the bellows provides a number of sharp corners and seams that would be prone to fatigue, cracking and eventually leakage.
The Hankins U.S. Pat. No. 4,482,072 discloses a complicated pump arrangement that would be expensive to manufacture. It would occupy a huge amount of space if remained in position upon the bottle after installation. The Marcus, '033 patent discloses a complicated pumping arrangement that would occupy an excessive amount of space if it were left attached to the bottle.
The Schneider U.S. Pat. No. 4,763,803 requires a separate pump and separate stopper arrangement that would require one or the other to be located every time the device is to be used. A similar device that employs separate pump and stopper is sold under the mark “Vacuvin”.
It is known that oxygen has a deleting effect on the quality of wine over a period of time. The chemistry of wine is very complex and the constituents can be in the hundreds. Many appear as trace elements and can be directly oxidized from prolonged exposure to oxygen.
Oxygen can also affect the visual appearance of wine, creating a clouding of the wine from oxidized coloring matter within the wine. In addition to the negative deteriorative effects of oxygen on both the flavor and the coloring of the wine, oxygen changes some flavor components into acetic acid.
BRIEF SUMMARY OF THE INVENTION
The present invention solves prior art problems and shortcomings by providing a simple and convenient air/oxygen removal system for bottled wines that employs a squeeze type bulb and a plug fitted to the open mouth of a wine bottle and that can remain with the wine bottle once air and oxygen have been evacuated.
The improved pump arrangement of the present invention expels any air from within the wine bottle that could contribute to the source of flavor or essence deterioration of wine that remains within the bottle after it has been opened. The present invention provides an improved wine bottle closure apparatus that evacuates air from a wine bottle that has a neck with a bottle opening that communicates with a bottle interior.
The present invention employs an improved wine bottle closure device with a specially configured hollow bulb structure that has a bulb interior fitted to a specially configured plug.
In one embodiment, the bulb is a ball or sphere.
In one embodiment, the plug fits the top of a wine bottle with a snap fit.
In one embodiment, the bulb extends below the plug, shortening the overall height of bulb, plug and bottle. With the present invention, it is not necessary to separate the vacuum pump and plug or stopper. It can then remain with the wine bottle until the contents are consumed at a later date.
The bulb structure includes a closure plug or stopper at its lower end portion that is sized and shaped to form snap fit and a seal with a wine bottle opening. A bottle closure plug attaches to the bulb. The plug has an open ended air flow channel that communicates with the bulb interior so that air can travel from the interior of the wine bottle to the interior of the bulb during pumping. The channel provides openings at end portions of the channel.
A first check valve is mounted to the plug. The first check valve enables air flow in an upward direction from the plug air passage to the plug interior and disallowing substantial air flow in a downward direction from the bulb interior.
A second check valve is mounted to the bulb structure. Either of the check valves can be of a type that can be opened to vent the bulb interior when not pumping. Alternatively, a relief valve can be optionally mounted on the bulb wall for releasing any vacuum.
A bulb flow outlet is carried by the upper smaller diameter section and enables air to flow from the bulb interior through the second check valve to the atmosphere.
The bulb structure is preferably a resilient structure having a memory that urges the bulb wall to return to an expanded position. When the bulb is squeezed, air is thus evacuated from the bulb interior via the bulb flow outlet. The bulb has a collapsed position that subjects the bulb interior to a vacuum or sub-atmospheric pressure as the wall attempts to return to the expanded position.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1-5 show the preferred embodiment of the apparatus of the present invention, designated generally by the numeral 10. Wine bottle pump apparatus 10 is shown in use with a wine bottle 11. The wine bottle 11 has a neck 12, tapered section 13 and a larger diameter lower section 14. The bottle 11 provides an interior 15 that is filled with wine 16 to be consumed.
Bottle 11 has an upper end portion 17. Cylindrically shaped collar 18 is positioned at upper end portion 17. An annular shoulder 19 extends between cylindrically shaped collar or annular rib 18 and neck 12 as shown in FIGS. 2-5. Outlet opening 20 is provided in the bottle 11 next to upper end portion 17.
In FIG. 3, arrow 21 schematically illustrates an assembly of bulb 22 and its plug or closure 40 to neck 12. The connection of plug or closure 40 to neck 12 at collar or rib 18 can include a snap fit or interlocking fit to cylindrically shaped collar 18 as annular shoulder registers under collar or rib 18 (see FIG. 5).
Bulb 22 provides a bulb interior 23. Bulb 22 provides a bulb wall 24 that is preferably spherically shaped as shown in FIGS. 1-5. Plug or closure 40 includes a cylindrically shaped outer wall 25, a cylindrically shaped inner wall 26, and a disk or donut shaped connecting web 27. Bulb 22 wall 24 can be attached to or be integrally formed with web 27. A pair of check valves 28, 34 are provided for pumping air/oxygen from bulb interior 23 and bottle interior 15.
Valve 28 pulls air from bottle 11 interior 15 when a user releases his or her finger 36 and thumb 37 from bulb 22 after squeezing the bulb 22. In FIG. 4, when the bulb 22 is squeezed as illustrated by arrows 38, air evacuates bulb 22 interior 23 as illustrated by arrows 35 in FIG. 4. The evacuating air indicated by arrows 35 passes through check valve 34 which is mounted in wall 24 of bulb 22.
When the user releases his or her finger 36 and thumb as illustrated in FIG. 5, the bulb 22 can have a memory so that it expands to its original spherical shape, illustrated by arrows 59 in FIG. 5. This action creates a vacuum within bulb 22 interior 23. Air contained within bottle 11 interior 15 travels through check valve 28 as illustrated by arrows 29 in FIG. 5.
An annular shoulder 30 is provided at the lower end portion of cylindrically shaped outer wall 25 as shown in FIG. 3. When applying bulb 22 and its closure or plug 40 to bottle 11, cylindrically shaped outer wall 25 deforms slightly so that cylindrically shaped collar 18 can fit into and occupy annular socket 39. Socket 39 is in between cylindrically shaped outer wall 25 and cylindrically shaped inner wall 26. As cylindrically shaped collar 18 enters annular socket 39, upper end 17 of bottle 11 engages connecting web 27 which acts as a stop to limit further movement of bottle 11 into socket 39. Simultaneously, annular shoulder 30 snaps or interlocks into position next to annular shoulder 19 as shown in FIGS. 3-5.
The bulb 22 and plug/closure 40 can be of a resilient material such as rubber, polyurethane, polypropylene, or other plastic or polymeric material or the like. In the position of FIGS. 4 and 5, the annular shoulder 30 is a retainer that holds the plug or closure 40 in position by engaging annular shoulder 19 of bottle 11. Each of the check valves 28, 34 can provide a valving member or disc 31 that opens and closes. Each of the check valves 28, 34 can include a valve body 33 having an opening or openings 32 therethrough. A closed position of check valve 28 is seen in FIG. 4. An open position of check valve 28 is seen in FIG. 5.
FIGS. 6-10 show an alternate embodiment of the apparatus of the present invention, designated generally by the numeral 41. Wine bottle pump apparatus 41 can be affixed to bottle neck 12 and cylindrically shaped collar 18 in the same fashion as the embodiment of FIGS. 1-5. Plug or closure 46 fits bottle 11 neck 12 as shown by arrow 42 in FIG. 8, wherein collar or rib 18 occupies socket 60. The embodiment of FIGS. 6-10 provides a bulb 43 that extends along the neck 12 as shown in FIGS. 6-10. This construction enables a user's hand 56 to extend around both bottle neck 12 and bulb 43 when pumping as shown in FIGS. 9 and 10. A user would thus grab the combination of bottle neck 12 and bulb 43 when air is to be pumped from bottle 11 interior 15. A beginning position is shown in FIG. 10. In FIG. 9, a user's hand 56 is shown gripping the combination of neck 12 and bulb 43, and the hand 56 compressing bulb 43.
Bulb 43 provides an interior 44 and a bulb wall 45. A plug or closure 46 is of similar construction to the preferred embodiment of FIGS. 1-5. The plug or closure 46 provides a cylindrically shaped outer wall 47 and a cylindrically shaped inner wall 48. Connecting web 49 spans between the upper end portions of the cylindrically shaped outer wall 47 and the cylindrically shaped inner wall 48 as shown in FIGS. 7-10.
As with the preferred embodiment, the periphery 50 of connecting web 49 can be integrally connected to bulb 43. A pair of check valves 51, 53 are provided. The check valves 51, 53 can be of the same construction and operation as the check valve 28. Arrow 52 in FIG. 10 illustrates an evacuation of air from bottle 12 interior 15 when a user releases pressure on bulb 43 as illustrated by the arrow 57 in FIG. 10. In FIG. 9, arrows 54 illustrate the discharge of air from bulb 43 interior 44 when a user compresses the bulb 43 as illustrated by arrow 58 in FIG. 9.
