Description

BACKGROUND OF THE INVENTION

The present invention relates to apparatus and methods for cleaning small objects and in particular to apparatus and methods for cleaning baby pacifiers and baby bottle nipples.

Parents and care givers commonly use pacifiers to comfort and quiet infants and provide nourishment from baby bottles through nipples attached to the baby bottles. Unfortunately, infants often play with their pacifiers and either rub the pacifier against soiled and unsanitary surfaces or drop the pacifier on the floor. Similarly, baby bottles are subject to contact with soiled and unsanitary surfaces or an infant may handle the nipple with dirty hands or the bottle may be dropped onto the floor. Parents and care givers are also often required to care for an infant away from home and often do not have a convenient way to clean soiled pacifiers and nipples.

U.S. Pat. No. 6,343,612 for “Portable Pacifier Cleaner and Container,” discloses a two compartment apparatus having a dry first compartment for storing a pacifier and a second compartment containing a liquid for cleaning the pacifier should it become soiled. Unfortunately, the apparatus of the '612 patent requires reuse of a dirty liquid which may contaminate the pacifier.

U.S. Pat. No. 5,402,810 for “Pacifier Storage and Washing Apparatus and Method,” discloses apparatus with liquid in the bottom portion and a shelf with openings to allow the liquid to enter a top portion holding a pacifier. Motion of the apparatus allows the liquid to enter the top portion to clean the pacifier. Unfortunately, the apparatus of the '810 patent also reuses dirty and/or contaminated liquid and may thereby contaminate the pacifier.

BRIEF SUMMARY OF THE INVENTION

The present invention addresses the above and other needs by providing a hand held self contained cleaning apparatus which includes a reservoir containing a single use cleaning and/or disinfecting liquid, a pump, and a nozzle for directing a spray of the cleaning and/or disinfecting liquid against a soiled nipple of a pacifier or baby bottle cap. The apparatus includes a platform for supporting the pacifier or bottle cap, a mouth for inserting the nipple into an area just above the nozzle, and a separator for preventing dirty liquid from returning to the reservoir. The spray is directed against a soiled nipple to loosen and remove soil from the nipple. After cleaning the pacifier or bottle cap, the dirty cleaning liquid is released so new clean liquid may be used for the next cleaning. The apparatus may be carried with other related items and used to clean the pacifier or bottle cap at any location and in particular away from home.

In accordance with one aspect of the invention, there is provided a self contained hand held nipple cleaning apparatus. The cleaning apparatus includes a housing, an upper portion of the housing for containing the nipple, and a nozzle connected to a pump residing inside the housing for providing a spray of cleaning liquid into the upper portion of the housing and towards the nipple. A horizontal landing above the upper portion supports a nipple flange and a mouth in the horizontal landing allows the nipple to extend downward through the horizontal landing into the upper portion of the housing. A short wall surrounds the horizontal landing and has a shape of an outline of the nipple flange. A reservoir in a base of the housing holds the cleaning liquid and a pump plunger extending from the pump horizontally through the housing allows operation of the pump. A suction tube is connected to an inlet of the pump and has a suction end in the reservoir for providing cleaning liquid to the pump.

In accordance with another aspect of the invention, there is provided a method for cleaning a pacifier. The method includes filling a reservoir portion of a pacifier cleaning apparatus with a cleaning liquid, positioning a pacifier into the cleaning apparatus with a pacifier nipple inserted through a mouth into an upper portion of the apparatus, pumping the cleaning liquid from the reservoir portion into the upper portion to clean the nipple, removing the cleaned pacifier from the cleaning apparatus, and disposing of the used cleaning liquid to allow subsequent use of fresh cleaning liquid.

DETAILED DESCRIPTION OF THE INVENTION

The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

A first hand held self contained spray apparatus 10a according to the present invention is shown cleaning a nipple 36 of a pacifier 30 in FIG. 1A. The hand held self contained spray apparatus 10a includes a housing 15 containing a cleaning liquid 28 and a pump 12. The pump 12 receives the cleaning liquid 28 held in a reservoir portion 15b in a base of the housing 15 through a pickup 18 and suction tube 16 connected to a pump inlet 12a and provides a spray 26 of the cleaning liquid 28 through a nozzle 20 connected to a pump outlet 12b by a pressure tube 22 into an upper portion 15a of the housing 15. The nipple 36 of the pacifier 30 extends downward through a mouth 44 in a horizontal landing 46 of a platform 11 into the upper portion 15a and a nipple flange 34 of the nipple rests on the horizontal landing 46 (also see FIGS. 2-5). The nipple 36 is thereby positioned in the spray 26. A single nozzle 20 is preferably solely attached to a single pressure tube 22 and preferably provides a spray 26 pattern across the nipple 36.

A plunger 14 for operating the pump 12 is attached to the pump 12 and extends horizontally through the side of the housing 15 and includes a vertical finger surface 14a for pressing to operate the pump 12. A removable cap 24 seals the base of the housing 15 and may be opened to add the cleaning liquid 28. The cap 24 may be screw-on or snap-on. The cleaning liquid 28 may be water or a disinfectant which is safely consumable by an infant, such as mouth wash or diluted mouth wash.

A second hand held self contained spray apparatus 10b including a chamber 32 according to the present invention is shown containing the pacifier 30 in FIG. 1B. The apparatus 10b is similar to the apparatus 10a, with an exception that the platform 11 is replaced by the chamber 32. The chamber 32 has a chamber cap 33 which may be screw-on or snap-on.

A pacifier 30 suitable for cleaning using the apparatus 10a or 10b is shown in FIG. 2 and a baby bottle cap 40 suitable for cleaning using the apparatus 10a or 10b is shown in FIG. 3. Both the pacifier 30 and the baby bottle cap 40 include the nipple 36 and a nipple flange 34. The pacifier 30 further includes a pacifier ring 38, and the baby bottle cap 40 further includes a screw-on cap portion 42.

Importantly, both the apparatus 10a and 10b include a solid separator 13 between the reservoir portion 15b and the upper portion 15a preventing used liquid 28 from returning to the reservoir portion 15b after becoming dirty or contaminated. As a result, the failure of known apparatus to prevent contamination by dirty liquid 28 is avoided.

While both apparatus 10a and 10b are shown with the spray nozzle 20, an embodiment of the present invention without a spray nozzle may be used as long as means are provided to pump the liquid 28 into the upper portion 15a for single use cleaning. For example, pumping may be provided by a squeezable reservoir portion, a feed tube extending to the bottom of the squeezable reservoir portion, and a one way valve between the reservoir portion and the upper portion to obtain a single use of the cleaning liquid 28. In another example, the apparatus may include the pump 12 used simply to pump cleaning liquid 28 into the upper portion 15a.

A top view of a platform 11 according to the present invention for holding a pacifier 30 during cleaning is shown in FIG. 4 and a cross-sectional view of the platform 11 taken along line 5-5 of FIG. 4 is shown in FIG. 5. The platform 11 includes the horizontal landing 46 for supporting the pacifier 30, and a short wall 48 surrounding the horizontal landing 46. The wall 48 has an inside face 48a creating an outline slightly greater than the outline of the nipple flange 34 of the pacifier 30. The nipple flange of the baby bottle cap 40 is generally round, and the inside face 48a of a platform wall 48 intended for use with the baby bottle cap 40 would generally also be round. The platform 11 further includes the mouth 44 which may be rectangular or round and is provided to allow the nipple 36 to pass through the horizontal landing 46 into upper portion 15a of the apparatus 10a and 10b (see FIG. 1A and FIG. 1B). Tabs 45 extend inwardly from the wall 48 and provide positive retention of the nipple flange 34 in the platform 11.

While the platform 11 is shown having an oval outline suitable for a pacifier, a platform may also be round to accept the baby bottle cap 40. The platform and wall 48 may further be sized for a particular pacifier nipple flange 34 size and/or shape, and the tabs 45 may be sized and positioned on the wall 48 for a particular pacifier nipple flange 34 size and/or shape.

A side view of the chamber 32 according to the present invention for containing the pacifier 30 or the baby bottle cap 40 is shown in FIG. 6 and a cross-sectional view of the chamber 32 taken along line 7-7 of FIG. 6 is shown in FIG. 7. The chamber 32 includes a container wall 50 and a container cap 33. The container cap 33 may be screw-on or snap-on. The chamber 32 is generally cylindrical in shape. The chamber 32 may include tabs 45 to hold the pacifier 30 in position for cleaning.

The apparatuses 10a and 10b are preferably made from plastic.

A method according to the present invention for cleaning a pacifier is described in FIG. 8. The method includes filling a reservoir portion of a pacifier cleaning apparatus with a cleaning liquid at step 100, positioning a pacifier into the cleaning apparatus with a pacifier nipple inserted through a mouth into an upper portion of the apparatus at step 102, pumping the cleaning liquid from the reservoir portion into the upper portion to clean the nipple, wherein the upper portion is separated from the reservoir to prevent used cleaning liquid from draining back into the reservoir, at step 104, removing the cleaned pacifier from the cleaning apparatus at step 106, and disposing of the used cleaning liquid to allow subsequent use of fresh cleaning liquid at step 108. Positioning a pacifier into the cleaning apparatus may comprise snapping the pacifier under tabs on a wall around a horizontal landing to retain the pacifier in the apparatus.

While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
