Abstract
The baster has a bellows for use in providing suction to draw basting liquid into a tapered tube, and compression to eject the liquid out of the tube. The bellows has a compression spring to increase the suction. A valve at the lower tip of the tube provides resistance to the unwanted outflow of liquid from the tube to greatly reduce or eliminate dripping.
Preferably, the valve has the form of a removable valve body inserted into the tube end, a flexible membrane over the upper inlet of the valve body, with a plurality of slits which cross one another. Preferably, the valve body forms a curved outlet passageway which allows the baster to be held at an angle closer to horizontal when basting or ingesting basting liquid.

Description
BASTER AND METHOD
This patent application is a continuation-in-part of U.S. patent application Ser. No.
13/065,010, filed March 11, 2011.
This invention relates to food basters, and particularly to basters for basting turkeys or other large fowl, or roasts, or any other foods for which basting is desired.
Food basters presently available usually include an elongated tube with an enlarged resilient hollow globe or bulb at one end, and sometimes a valve inside the hollow tube. The baster is used by hand. The bulb is compressed to expel air or liquid out of the tube, and is released to draw liquid into the tube.
There are several problems with such prior baster devices. One is that the baster often drips when the tube is filled with basting liquid and the baster is moved from one place to another. Presently available basters, even those with valves, sometimes do not sufficiently protect against dripping of the basting fluid from the tube so that excess leakage occurs.
A second problem, one realized by the applicant, is that suction provided by the compression and release of the rubber bulb is limited due to the structure of the bulb and the capabilities of the human hand in manipulating the bulb.
Another problem is that some prior basters direct a stream of ejected basting liquid in a direction or in a pattern making basting more difficult.
Accordingly, it is an object to provide a basting device and method which either solve or ameliorate the foregoing problems.
In particular, it is an object of the invention to provide a baster with increased useful suction and ejection capacity to increase the basting liquid volume handling capabilities of the baster.
It is a further object to provide such a device which is relatively less prone to unwanted dripping of basting liquid from the device.
It is a further object to provide such a basting device which is relatively inexpensive to manufacture, is relatively easy to disassemble for cleaning, is made of dishwasher-proof materials, and is relatively compact in size.
In accordance with the present invention, the foregoing objects are met by the provision of a basting device in which a bellows replaces the usual rubber squeeze bulb to generate suction and ejection pressures to handle substantial quantities of basting liquid. The bellows is believed to be capable of creating substantially more suction than the usual squeeze-bulb of the same size.
In addition, a spring mounted inside the baster bellows further increases the suction/ejection liquid capacity of the baster.
A further aspect of the invention lies in the provision of a valve at the tapered narrow tip of the tube of the baster, with the valve providing resistance to the flow of liquid sufficient to eliminate or greatly reduce instances of unwanted dripping of liquid from the tube.
Preferably, the valve member is a flexible membrane with slits, and the membrane is easily accessible to ease the removal of clogging particles. The valve member is most preferably located at the innermost end of a removable tip structure at the narrow tip.
Preferably, the lower tip structure of the tube is angled to provide a re-directed outward stream of liquid to facilitate basting, and a downwardly-curved flow passage is formed in the tip structure to further facilitate and direct the flow of basting liquid towards the food item being basted.

GENERAL DESCRIPTION
The baster device 10 shown in Figures 1 and 2 of the drawings has an elongated tapered hollow tubular body portion 12, with a relatively large opening at the upper end 14 of the tube, and a relatively small opening at the narrow end 16 of the tube.
Connected to the tube 12 at its tipper end 14 is a bellows 18 with a short tubular extension 20 (Figure 2) with screw threads mating with screw threads 22 on the inside surface of the tube at its upper end 14. A flange 24 extends outwardly from the outside of the tube 12 at the upper end 14 to serve as a finger-gripping surface so that the user can apply pressure to compress the bellows by pushing on the rear surface 26 of the bellows with the thumb while gripping the flange 24 with other figures of the same hand.
Referring now to Figures 3 and 4, as well as Figure 2, the valve structure at the lower tip 16 of the tube 12 is formed conveniently on an insert 28 which is fitted into the opening in the end of the tube 12. The insert 28, as shown in Figures 3 and 4, has a reduced external diameter at 34 and a flange at 36 which mates with a similarly shaped receiving structure at the end of the tube body 12 so that the insert 28 can be snapped into and pulled out of the end of the tube 12 relatively easily so as to facilitate cleaning the tip structure to keep it sanitary.
The insert 28 has an internal cylindrical passage 38 which is of a significantly smaller diameter than the end of the tube 12 so as to provide a certain amount of restriction to the flow of liquid.
Covering the end of the passage 38 is a flexible membrane 30 secured to the angled end portion 40 of the insert 28. The membrane has a plurality of crossed slits 32 to serve as restricted inlet-outlet openings.
The surface 40 at the lower end of the insert 28 forms an acute angle with the longitudinal axis of the tube 12 to better facilitate drawing up liquid from the bottom of the pan where the baster is held at an angle to the pan. Also, the ejected stream of basting liquid is directed at an acute angle to the axis to facilitate basting.
Preferably, the amount of pressure differential across the membrane 30 required to open the slits 32 to allow liquid to pass through is great enough to prevent most or all dripping of liquid from the tube 12, even when the tube is oriented vertically with a full column of liquid above the membrane 30.
Preferably, the diameter of the tube portion 38 of the insert is dimensioned and the membrane 30 is designed so that the amount of pressure differential across the membrane necessary to open the slits is a small fraction of the total amount of pressure that can be provided by operation of the bellows. Therefore, excessive force need not be applied to the bellows merely to open the valve.
The bellows preferably is molded of TPR (thermoplastic rubber), or silicone rubber and has multiple folds which collapse upon one another to reduce the volume of the bellows to a very low fraction of the starting volume of the bellows. This provides an enhanced volume of fluid movement in the basting device. The resiliency of the material provides good suction pressure when the bellows is released.
The bellows can be made with very thin walls, if desired, by inserting a compression spring inside it to enhance its suction production capabilities, as shown in Figures 5-8.
Preferably, the outside dimensions of the bellows 18 are of the same order of magnitude as that of the flange 24 so as to keep the profile of the baster device relatively slender.
The tube 12 preferably is molded of dishwasher-proof high temperature co-polyester resin such as "Tritan" resin sold by Eastman Chemical Co. of Tennessee.
Advantageously, the insert 28 and the membrane 30 are formed as an integral unit made of high-temperature silicone rubber. In other words, the insert 28 shown in Figure 4 is formed in a single mold.
To wash out the inside of the bellows and the tube, one can remove the insert 28 fiom the lower tip and unscrew the bellows from the tube, and wash the separate elements.
A further improvement embodiment of the invention is shown in Figures 5 through 8 of the drawings.
The baster 50 shown in Figures 5 through 8 is very similar to the one shown in Figures 1 through 4.
Referring first to Figures 5 and 6, an elongated, tapered tube 52, made out of transparent plastic, is provided. A bellows 54 at one end of the tube is provided for the same purposes of bellows shown in Figures 1-4.
A valve body 53 is fitted into the narrow end of the tube 52, and has an exit passageway 58 and a membrane 76 with crossed slits forming a valve attached to the valve body.
Referring to Figure 6, which is a cross-section taken through lines 6-6 of Figure 5, the bellows 54 has a helical spring 56 mounted inside of it. Thus, Figure 6 shows the embodiment of the invention described in the parent application on page 6, but not shown in the drawings of the parent application. The helical spring is seated against a ledge 70 formed in the inside wall at the right- hand opening of the tube 52. The spring preferably is made of stainless steel, but can be made of spring-forming plastic.
The right-hand end of the helical spring 56 bears against an annular plate 58 (also see Figure 7) which is secured to the end wall 60 of the bellows 54.
The end wall 60 has an inwardly-extending circular projection 62. The projection 62 extends through the central hole 65 (Figure 7) of the plate 58 with a friction or interference fit so as to hold the plate 58 securely against the rear wall. Also, the plate 58 is secured to the rear wall 60 by means of adhesive.
The right-hand end of the spring 56, as shown in Figure 6, is secured to the plate 60 by means of projecting pins 64, which have broad heads, as shown in Figure 6, and thus hold the wire of the right-hand end of the spring securely against the plate 60.
Thus, the spring 56 is secured inside the bellows 54 at its rear wall 60, and abuts against the ledge 70. Preferably, the spring 56 is mounted with a moderate amount of compression when it is inserted into its mounting position so as to urge the bellows 54 into an open position.
The bellows 54 is secured to the outer wall at the right end of the tube 52 with a snap-fitting structure. This structure includes a circular ridge 68 extending outwardly from the tube end, and a matching groove 66 on the internal surface of the left portion of the bellows 54.
Because the bellows 54 is made of relatively flexible plastic material, the bellows can be snapped on and snapped off of the end of the baster tube 52, and the spring 56 will automatically seat against the ledge 70, where the parts are snapped back together after washing.
The valve body 53, as shown in Figures 5-8, has an inner ridge 74 which seats in a circular recess on the internal surface of the end of the tube 52 so that it snaps into position and can be removed relatively easily by merely pulling it away from the tube.
The valve body 53 differs from the one shown in Figures 1-4 in two respects.
First, the valve member 76 is at the inlet end of the body 53 instead of the outlet, and the passageway leading to the outlet opening 78 is curved downwardly so as to issue the stream of basting liquid downwardly towards the food item it is being used to baste, without having to lift the bellows end of the baster at an exceptionally high angle.
This arrangement allows the basting liquid to be dispensed while the baster forms a lower angle, with respect to horizontal, so as to facilitate dispensing the basting liquid in a stream properly aimed at the food item. This has the advantage of allowing basting to proceed despite obstacles such as oven racks or the like, and thus makes it easier to use the baster.
A further advantage is that when the baster is held at such a relatively low angle when the baster is moved towards or withdrawn away from the food item, the pressure on the valve 76 from any liquid in the baster is believed to be minimized so as to further minimize unwanted dripping.
The location of the membrane 76 forming the valve at the inlet to the valve body 53 has the advantage that it eliminates or minimizes any tendency that there might be for the liquid to spray out as it issues from the baster tip. That is, the curved passageway leading to the outlet 78 serves to concentrate the liquid into a desirable, relatively steady stream to prevent overspray and other deleterious effects which might otherwise occur.
In use, after a turkey or other fowl, or a large roast, etc. has baked for a certain length of time, juices commonly form in the pan in which the food item rests while being baked. After the baking process has progressed to a certain degree, the lower tip 53 of the basting device is inserted into the liquid when the bellows 18 is compressed, and then the bellows is released.
This will draw a substantial amount of liquid from the pan into the tube. Then the baster can be carried from one pan to another pan, to baste another food item, if desired, or it can be used to baste the food item in the same pan. In either case, unwanted dripping is either eliminated or greatly minimized.
As it can be seen from the foregoing, the basting device and method of the present invention meet the objectives set forth above. The bellows device is capable of moving substantially increased volumes of liquid, even while maintaining a relatively slim profile. The valve structure minimizes or eliminates unwanted dripping and is easily accessible to remove clogging food particles. The baster device is easy to disassemble and clean and reassemble for sanitary use.
The above description of the invention is intended to be illustrative and not limiting.
Various changes or modifications in the embodiments described may occur to those skilled in the art. These can be made without departing from the spirit or scope of the invention,

The baster device 10 shown in Figures 1 and 2 of the drawings has an elongated tapered hollow tubular body portion 12, with a relatively large opening at the upper end 14 of the tube, and a relatively small opening at the narrow end 16 of the tube.
Connected to the tube 12 at its tipper end 14 is a bellows 18 with a short tubular extension 20 (Figure 2) with screw threads mating with screw threads 22 on the inside surface of the tube at its upper end 14.

Referring now to Figures 3 and 4, as well as Figure 2, the valve structure at the lower tip 16 of the tube 12 is formed conveniently on an insert 28 which is fitted into the opening in the end of the tube 12.
