DETAILED DESCRIPTION
(13) Referring now to the drawings and in particular to
(14) Bulb pump portion 20 at its rear end 22 includes a one-way valve 24. One-way or check valve 24 allows air into bulb pump portion 20 when bulb pump portion 20 is expanding after being squeezed. A negative pressure caused by the expansion opens a flap (not illustrated) of one-way valve 24, allowing air into the bulb pump portion 20 as it expands. The flap of one-way valve 24 closes once bulb pump portion 20 is done filling with air. When the user squeezes the bulb pump portion, the pressure seals the flap closed tightly, forcing air out of diffuser 40.
(15) In an embodiment, bulb pump portion 20 of air deliverer 12 at its rear end 22 is molded to define a hole that accepts one-way valve 24, e.g., press-fittingly or adhesively. The hole may be expanded so that an inner molding tool may be pulled from bulb pump portion 20 and stem portion 30 of air deliverer 12 without tearing either bulb pump portion 20 or stem portion 30.
(16) Bulb pump portion 20 of air deliverer 12 at its front end 26 transitions to neck 32 of stem portion 30, which in an embodiment is a smooth radius transition. Stem 30 may be a hollow cylinder having an at least substantially constant diameter from its proximal end 32 to its distal end 34 as illustrated in
(17) Diffuser 40 may be removeably press-fitted into, press-fitted onto, threaded onto, threaded into, compression fitted to, adhered to, and/or formed integrally with or permanently attached to distal end 34 of stem portion 30 of air deliverer 12. In the illustrated embodiment of
(18) Diffuser 40 in one embodiment is made of a sintered, porous or perforated material. Diffuser 40 may be layered to have or formed to have small diffusing holes, openings or apertures. Diffuser 40 may alternatively be of a polymer material, wood, cork, rubber, metal or combinations thereof. Diffuser 40 may be plastic and be formed with, e.g., injection molded with stem portion of 30 of air deliverer 12. Diffuser 40 may be an air stone. The air stone may be one used to deliver air into water, typically used for fish tanks. Diffuser 40 causes the air delivered through stem portion 30 to diffuser 40 to be separated into small bubbles, such as microbubbles, when delivered to the wine. The small bubbles help the air to mix with and diffuse into the wine as opposed to simply migrating to the top of the glass, without mixing.
(19) In one embodiment, diffuser 40 is a stainless steel (e.g., type 304 or 316 stainless steel) porous cup or porous capped tube segment. The pore size may, for example, be less than one-hundred microns, such as ten microns, five microns, two microns, one micron or less than one micron, such as a half-micron or fraction of a micron. Smaller pore sizes make smaller air bubbles, which helps the air to diffuse into the wine. Diffuser 40 is in one embodiment generally impermeable to liquids. That is, diffuser 40 is generally hydrophobic and will not allow wine or liquids to enter. Air will thus be present in diffuser 40, stem portion 30 and bulb pump portion 20 when the bulb pump portion is actuated.
(20) Diffuser 40 as illustrated in
(21) Bulb pump portion 20 of air deliverer 12 in the illustrated embodiment has a bulb shape. The bulb shape may be rounder, like a tennis ball or flatter, like an American football or rugby ball. In the embodiment illustrated in

(28) Base pump portion 120 at its rear end 122 again includes a one-way valve 24. One-way or check valve 24 allows air into base portion 120 when base portion 120 is expanding after being squeezed. A negative pressure caused by the expansion opens a flap (not illustrated) of one-way valve 24, allowing air into the base portion 120 as it expands. The flap of one-way valve 24 closes once base portion 120 is done filling with air. When the user squeezes the base pump portion 120, the pressure seals the flap closed tightly, forcing air out of diffuser 40.
(29) In an embodiment, base portion 120 of bottle-shaped air deliverer 112 at its rear end 122 is molded to define a hole that accepts one-way valve 24, e.g., press-fittingly or adhesively. The hole may be expanded so that an inner molding tool may be pulled from base portion 120 and neck portion 130 of air deliverer 112 without tearing either base portion 120 or stem portion 130. Rear end 122 of base portion 120 may be relatively flat so that aerator 10c may be set on and supported by rear end 122 of base portion 120, allowing neck portion 130 and diffuser 40 to extend upwardly without further support structure, like the placement and support of a wine bottle.
(30) Base pump portion 120 of air deliverer 112 at its front end 126 transitions to neck portion 130, which in an embodiment is a smooth radius transition. Neck portion 130 may be a hollow cylinder having an at least substantially constant diameter (narrower than diameter of base portion 120) from its proximal end 132 to its distal end 134. Neck portion 130 may alternatively be tapered, e.g., narrowed from its proximal end 132 to its distal end 134 as illustrated in
(31) Diffuser 40 may be removeably press-fitted into, press-fitted onto, threaded onto, threaded into, compression fitted to, adhered to, and/or formed integrally with or permanently attached to distal end 134 of neck portion 130 of air deliverer 112. In the illustrated embodiment of
(32) Diffuser 10c may include an integral internal step at the distal end of the stem or neck portion to catch diffuser 40 as it is inserted into the stem or neck portion. The internal step may be the same as or like internal step 36 of
(33) It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
