## Background
CLAIM OF PRIORITY 
This application is a continuation in part of U.S. Ser. No. 10/628,097 filed Jul. 28, 2003, now abandoned, and U.S. Ser. No. 10/750,447, filed Dec. 30, 2003, now U.S. Pat. No. 7,226,230.


FIELD OF THE INVENTION 
The present invention relates to flowable material spreaders for use on hand manipulatable dispensers, and more particularly to spreaders at the nozzle ends of such dispensers.
BACKGROUND OF THE INVENTION 
Spreadable foods are common table items and are enjoyed by many all over the world. There are numerous types of foods that can be spread. Typical spreadable foods include peanut butter, frosting, butter, mayonnaise, jelly, ice cream toppings, salad dressing and cream cheese and other edible spreads for use on bread, crackers, and the like. Often, a butter knife, spatula, or other similar device is used to spread the food onto the bread, cracker, or other item. However, these utensils can become lost on or at outdoor celebrations and picnics, or other events, or need to repeatedly dip a spreader knife into a jar. Additionally, material accumulates on the knife and jar edges, as well as crumbs of other materials can accumulate in the jar.
A number of patents have issued related to food dispensers and the like. U.S. Pat. No. 5,377,874 discloses a liquid dispenser for dispensing fluid condiment materials, such as ketchup, mustard and mayonnaise as well as other liquids such as medicated salves, lotions and ointments. The dispenser includes a tubular body with a spherical plunger element connected to a spreader paddle member disposed within a tubular body. Upon external manipulation of the tubular body, the spherical plunger and spreader paddle arrangement is urged toward a dispenser nozzle for release of condiment filling contained therein. The sanitary spreader paddle simultaneously protrudes from within the tubular body as condiment filling is being evacuated. As a result, the user may evacuate the entire volume of condiment filling within the dispenser as well as spread the deposited condiment filling on a food article to be eaten. In a medical application of the invention, the dispenser includes an integral applicator swab which is connected to the spreader paddle and resides within the plunger. The spreader paddle is separated from the plunger to expose the cleansing swab for use on the body.
U.S. Pat. No. 5,330,075 is directed to a food condiment dispenser for dispensing fluid condiment materials, such as ketchup, mustard and mayonnaise. The dispenser includes a tubular body with a spherical plunger element connected to a spreader paddle member disposed within a tubular body. Upon external manipulation of the tubular body, the spherical plunger and spreader paddle arrangement is urged toward a dispenser nozzle for release of condiment filling contained therein. The sanitary spreader paddle simultaneously protrudes from within the tubular body as condiment filling is being evacuated. As a result, the user may evacuate the entire volume of condiment filling within the dispenser as well as spread the deposited condiment filling on a food article to be eaten.
U.S. Pat. No. 4,957,226 is directed to an automatic food dispensing method, apparatus and utensil primarily for use in fast food restaurants, bakeries, and the like. The method and apparatus comprise a pumping system from a supply through a pump in a controlled amount with a reverse action of the pump after the appropriate amount has been dispensed in order to avoid it dripping. Other drip proof arrangements, such as valving are also utilized optionally. The utensil comprises a handle attached to a container and spreading utensil such as a spoon, ladle, or the like, wherein predetermined portions of a food or substance used in a food may be dispensed either continually or as predetermined quantities. The device consists of a spoon or other appropriately shaped utensil attached to a hollow handle which terminates in a non-interfering connection with the interior of the utensil at one end and terminates at the other end in a connection to a food supply source.
U.S. Pat. No. 6,153,238 is directed to a packaged cheese product comprising a hermetically sealed container, preferably a pouch, made out of flexible material; a decorator tip or adaptor therefore inside the container, a cheese product inside the container and a cap for closing the decorator tip when the pouch is partially emptied. The cheese product can be extruded after cuffing the corner off of the pouch and seating the decorator tip in the resulting opening. Cheese in decorative shapes can then be easily applied as a garnish on food items and the pouch can then be re-closed by capping the decorator tip. The cap preferably has a bulb member that fits inside the decorator tip and a skirt member that fits around the outside petals of the preferred decorator tip.
U.S. Pat. No. 4,844,917 is directed to a cake frosting technique and assembly including a disposable frosting bag for home or commercial use to render the frosting or decorating of cakes or other pastries more convenient and expeditious by the complete elimination of the need for expensive and messy heretofore-used large commercial squeeze bags, or manually whipped and spread frosting, or expensive aerosols. The invention contemplates the ready coloring or tinting of the frosting to any desired hue within a wide range with any particular color and further contemplates the imparting of any desired flavoring to the frosting by the separate and conveniently associated provision of the aforesaid disposable bag containing a neutral or white frosting along with a plurality of separate color tint tubes and a plurality of separate flavor taste tubes, whose contents are to be admixed respectively with the base frosting material to achieve a desired blend for the ultimate decorative and taste effects contemplated.
U.S. Patent Publication No. 2002/0000441 discloses an aperture forming structure, which when attached to or integrally formed in dispenser packages for flowable substances allows reclosure and single or multiple uses. The aperture forming structure includes a breakaway tip member of thermoformable plastic. The break away tip includes a hollow protrusion from a surface. The intersection of the hollow protrusion and the surface is a fault line. Rupturing of the fault line creates an aperture from which the contents of the dispenser package may exit. A cap may be integrally formed with the aperture forming structure and detached for protecting the hollow protrusion or for closing the aperture created when the fault line is ruptured. The aperture forming structure can be made by heating a relatively stiff substantially flat thermoformable sheet of and then stretching the sheet to create a first and a second hollow protrusion in a tiered configuration. A rupture line is placed at the intersection of the first and the second protrusions. The sheet may be attached to a pouch or containment member formed from a flexible sheet which contains any flowable substance.
While there have been a number of prior systems directed to food spreaders, none have adequately addressed the need for ease of use and convenience. There is a need for a system to easily, quickly and accurately spread material such as edible substances, being dispensed from containers such as squeeze tubes or bottles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to the drawings, wherein like reference numerals refer to the same components across the several views and in particular to FIGS. 1 and 2, there is shown a spreader 10. The spreader 10 contains dispensable, flowable food material such as peanut butter, jelly or other such edibles. When the container is squeezed, the material flows through a nozzle 11 which tapers toward an outlet 12 which is elongated laterally, to provide a dispensed layer 13 of material of thickness 14 substantially less than its width 15. A flexible spreader 17 in the form of a flap or blade, or spatula, is provided at the nozzle exit, to face the layer 13 exiting from the nozzle, whereby the user can manipulate the spreader, and its undersurface, via container manipulation, to further spread or shape the dispensed layer 13. The flap or blade may be stiff or sufficiently flexible to shape the layer 13. Note its lateral length 19 is substantially greater than its width. The tip of the nozzle or blade should be flexible
The nozzle 11 may be stiff or may be flexible as in FIG. 4 to assist flexing of the spreader during container manipulation to cause the spreader to shape the layer 13 deposited on a surface 21 or spread it only after it is dispensed. The latter may be a food surface such as on bread, or other substances. FIG. 3 shows the nozzle outlet 22, which has lateral width 22a substantially greater than its thickness 22b. The nozzle may be a cap on the container, or may be integral with the container. A snap-on or threaded fitting 24 connects the nozzle to the container, in FIG. 4. FIG. 4 also shows the nozzle outlet 22 having a linear edge profile along the lateral width dimension 22a (see FIG. 3) of the periphery when the outlet 22 is viewed from the side of the nozzle 11, the linear edge profile defined at a constant distance from the fitting 24 along the lateral width dimension 22a along a central axis of the nozzle 11. FIG. 4 also shows that the forwardly-projecting side wall is configured to funnel dispensed material from the fitting 24 to the nozzle outlet 22 along a sloped path. FIG. 4 also shows a nozzle 11 wherein the distance from the nozzle outlet 22 to the fitting 24 exceeds a thickness of the fitting 24. As shown in FIG. 4a, the extruded product can have a wavy texture.
FIGS. 5 and 6 show a nozzle 32, tapering toward a narrowed exit 33 with a spreader flap or blade 34 overhanging that exit. FIG. 6 shows a cap 190 that receives the nozzle with snap-ring retention at 188 in a cap recess 188a of nozzle end 32a. Cap inner wall 189 forms a recess to receive the nozzle. A plug 192 on the cap plugs outlet 33. FIG. 7 shows the exit 33 as laterally, elongated with narrowed width or height. The nozzle entrance is seen at 87, in FIG. 8. FIG. 9 shows dispenser threads 36 to which the nozzle may threadably or otherwise attach. FIG. 10 shows in frontal view the annular end of the thread 36. See end opening 10a. 
FIG. 11 shows a flexible nozzle 40 that tapers toward an outlet 41, such as an elongated slit. The nozzle tip 40a serves as a spreader and preferably is positioned so that it can be seen when in use. The nozzle has a fitting 43 that threadably attaches to dispenser threads 44, as seen in FIG. 12. Nozzle may alternatively be positioned via a snap and release mechanism.
FIG. 13 shows a spreader flap 46 that has a laterally elongated serrated edge 47 to engage the dispensed layer 48 being dispensed. As a result, the layer 48 has an attractive striated appearance. The nozzle can be waved laterally back and forth to produce wavy elongated striations on the dispensed layer surface. FIG. 14 shows similar serrations 50 on the end of a nozzle 40b. A flap 51 can be attached to the nozzle to overlie the serrations, or part of same.
In FIG. 15, the flap or blade 60 is carried for adjustable movement, as by a carrier or adjuster 61 on the nozzle. A finger engagable protrusion 61a on the carrier is manipulated to move or slide the blade and carrier toward or away from the nozzle exit 41a, thereby to adjust the exposure of the blade to the dispensed material, to provide additional flexibility of use of the blade. Grooving 63 in the nozzle in the form of a threaded cap 63a, guides the adjuster. FIG. 16 shows the blade in extended forward position. The dispensing nozzle cavity appears at 64. FIG. 18 is a top plan view of the FIG. 16 adjuster. stature 17 shows the adjuster at the bottom side of the nozzle 93, having an exit 93a and pusher. The option of depositing the layer 113 without interference with the spreader flap or blade, is preserved.
In FIG. 19, the spreader 110 as supported is angled, relative to the nozzle or its bore, so that the spreader flap terminal 110b is sufficiently offset from the nozzle outlet 112a by a sufficient distance, that the terminal tip 110b does not engage the top 113a of the deposited layer 113, as during depositing of the layer. Terminal 110b may consist of an elastomer such as rubber. Outlet 112a may be laterally elongated as in FIG. 7.
In FIG. 19a the nozzle is now further tilted, as at angle α, so that the spreader blade terminal tip 110b engages the surface of the layer 113, for spreading purposes. Terminal 110b is shown as arcuately flexed near the tip, to smoothly engage and spreadably deform surface 113a, as the nozzle is moved to the right, relative to 113. Note that the spreader body at 110c upwardly of terminal 110b is thickened so as not to flex, and so as to positively position the terminal 110b as it accurately wipes along surface 113a. Terminal 110b may or may not be flexible, but is preferably arcuately flexible to smooth and spread surface 113a, as the nozzle and supply container are manipulated.
Body 110c tapers toward the tip or terminal. This construction, as shown, lends itself to ease of cleaning of interior surfaces 128, 129, and 130, as well as cleaning of the terminal. Note the greater than 90° angularities of adjacent surfaces 128 and 129, and 129 and 130, avoiding small gaps. The spreader terminal at 110b may have elongated lateral length, of dimension substantially greater than the nozzle discharge opening dimension, as described above in other FIGS., for engaging the widened surface area of 113, achieved during spreading.
FIG. 20 shows a curved flap or blade to conform to curvature of an edible, such as a corn cob. See laterally elongated nozzle outlet 22 having narrowed width 22b. A downwardly concave spreader flap or blade 17a is shown as above the outlet 22, and of lateral elongation greater than outlet 22 lateral elongation, indicated at 22a. 
FIG. 21a shows an alternate embodiment of the present invention that combines a knife and a spreader 200. The spreader 200 includes a container 201, that can hold a spreadable food F, such as peanut butter, butter, cheese, and the like. In a preferred embodiment of the present invention, the container 201 is flexible so as to allow a user to squeeze the spreadable food F. A knife nozzle 210 is attached to an open end of the container 201, and has an opening 220 to allow the spreadable food F to be transferred from the container 201 to an item such as bread, crackers, and the like. The knife nozzle 210 can then be used to spread the spreadable food F as desired.
FIG. 21b illustrates another embodiment of the present invention that combines a spatula and a spreader 200′. The spreader 200′ includes a container 201′, very similar to the container 201 above, that can hold a spreadable food F, such as peanut butter, butter, cheese, and the like. In a preferred embodiment of the present invention, the container 201′ is flexible so as to allow a user to squeeze the spreadable food F. A spatula nozzle 210′, which may be flexible, is attached to an open end of the container 201′, and has an opening 220′ to allow the spreadable food F to be transferred from the container 201′ to an item such as bread, crackers, and the like. The knife nozzle 210′ can then be used to spread the spreadable food F as desired.
Referring now to FIGS. 22a and 22b, another embodiment of a spreader 300 is illustrated. The spreader 300 includes a container 301, having a base 302 and a lid 303, that can hold a spreadable food F, such as peanut butter, butter, cheese, and the like. A detachable handle 310 is mounted on the container 301 at an attachment point 312 for transport and storage, to allow the spreader 300 to have less of a profile and take up less room. A dispenser nozzle 320 is mounted on the exterior of the container 301 to allow for the spreadable food in the container to be pushed out and onto a receiving food, such as bread, crackers and the like. When the spreader 300 is to be used, the detachable handle 310 is detached from the attachment point 312 and is mounted at mounting point 311, where it comes into engagement with a plunger 315, located in the lid 303. Additionally, the dispenser nozzle 320 may be rotated up or down, or flipped up in order to facilitate dispensing or storage as the case may be. When the handle 310 is depressed in the direction of arrow ‘P’, then the handle 310 exerts downward pressure on the spreadable food in the container 301, and forces the spreadable food out of the dispenser nozzle 320, and onto the receiving food. The interior of the dispenser is beveled 313 to facilitate the removal of all material. While this embodiment has be described in the context of longitudinally thrust plunger, it is to be appreciated that other equivalent structures could fulfill this function. For example the plunger could be thrust downward by means of a screw activated compression mechanism.
Illustrated in FIG. 23 is another embodiment of a spreader 400. The spreader 400 includes a container 401 and a nozzle 420. The container includes a threaded end 426 and is capable of receiving a bag 410, which in turn holds a spreadable food such as peanut butter, butter, cheese, frosting, and the like. The bag 410 may be omitted altogether. The bag 410 is flexible in a preferred embodiment of the present invention and can be folded over the threaded end 415 of the container 401. The nozzle 420 includes an opening 425 and a threaded end 426 which threadedly engages the threaded end 426 of the container 401 to secure the nozzle 420 to the container 401. Additionally, the bag 410 is then secured into place as the overlap portion is secured between the threaded end 426 of the nozzle 420 and the threaded end 426 of the container 401.
Referring now to FIGS. 24 and 25, another embodiment of a spreader 500 is shown. The spreader 500 includes a container 501, and a wide nozzle 520. Disposed within the container 501 is a bag 540 that can hold a spreadable food F, such as peanut butter, butter, cheese, frosting, and the like. The wide nozzle 520 is mounted at an open end 526 of the container 501, and includes an opening 525. Mounted on the container 501, at the opposite end 527 is a handle 510. The handle 510 includes a plunger 515, such that when the handle 510 is depressed in the direction of arrow ‘Q’, the plunger 515 forces the spreadable food contained within the bag 540 out through the opening 525 of the wide nozzle 520 and onto a receiving food, such as bread, crackers, cake, and the like. Additionally, a cap 530, having a cavity 531 substantially in the shape of the wide nozzle 520, can be mounted on the container 501 at the wide nozzle 520 in order to allow the spreader 500 to be stored standing upright.
FIG. 26 illustrates yet another embodiment of a nozzle in accordance with the present invention. In this embodiment, a rubber or flexible nozzle 600 is affixed to a threaded member 610 and extended coaxially thereto. The rubber/plastic nozzle 600 can function as a spreader.
FIG. 27 is still a further embodiment of nozzles in accordance with the present invention. FIG. 27 illustrates a nozzle 700 which either may be stiff or comprise a member expandable in accordion style when pressure is applied.
FIGS. 28a and 28b are still yet a further embodiment of a spreader in accordance with the present invention. In this embodiment, the spreader is a cylindrical casing 800 with an adjustable spine 802, connected to an adjustment mechanism 804 and nozzle 807 permit the flow of condiments such as spread dressing. It is to appreciated that the adjustment mechanism 804 may comprise a drive crew or other similar device to longitudinally move the nozzle 807. The nozzle 807 may have holes to permit the flow of material there through. When the adjustment mechanism, is 804 pulled upward the nozzle 807 pulls upward and permits the flow of material. When pressure is applied the nozzle extends stiffly outward. This embodiment is similar in its operation to a garden nozzle. In a modified embodiment shown in FIG. 28b, the mechanism can have two positions, “on” and “off” 806, 808.
FIGS. 29 and 29a illustrate yet another nozzle spreader embodiment. In this embodiment, the nozzle spreader comprises a flat, wide nozzle 900 having a plurality of shaped holes 902. The nozzle can have a flip cap 904, for example, and may have a cap or closure which has protrusions 906 to cover the holes. This embodiment is ideal for salad dressings or the like. As shown in FIG. 29a, the bottle can have a threaded attachment 908 and adjuster 910 to adjust the flow of material.
FIG. 30 is a related embodiment to that of FIG. 29. In this embodiment, the nozzle comprises a flat, wide nozzle 1000 that inserts on a wide flange top 1002. The nozzle has a plurality of holes 1004 which may be beveled outward. The number, shape and position of the holes can be varied. This embodiment is ideal, for example, for ice cream toppings and salad dressings and other viscous food products. In a preferred embodiment, this bottle is a unitary structure including the novel flange top.
Finally, FIGS. 31 and 31a illustrate yet another nozzle embodiment. In this embodiment, the nozzle/spreader comprises a wide but narrow slit flange 1100 which is affixed to the bottle or tube 1101. The corners of the nozzle can be straight or cornered. This embodiment may include an internal support or stilt 1102 to prevent the nozzle from collapsing.
In view of the foregoing disclosure, some advantages of the present invention can be seen. For example, a novel spreader has been disclosed. The novel spreader easily, quickly and accurately spreads material such as edible substances, being dispensed from containers such as squeeze tubes or bottles.
Referring to FIGS. 32a to 32c, alternative embodiments of the spreader dispenser of this present invention for viscous materials, salad dressings, mustard, ketchup, taco sauce, ice cream toppings, syrups and other semi-liquid and squeezable products. As seen in FIGS. 32a and 32b, the invention includes a bottle of food product 1202 containing a dome-shaped spreader/applicator 1210. The dome-shaped spreader/applicator 1210 has an outer lip 1212 which snaps onto the container neck to hold it secure. The dome-shaped spreader 1210 has a plurality of apertures or orifices 1220 which are position angle outward so that the dispensed product spreads out evenly when applied. The dome application thus functions to spread out the food product in a wide array and with uniformity. The orifices 1220 of the dome 1210 can be straight (in line) (FIG. 32c) or may be dispensed over the body of the dome 1225. In one embodiment the dome-shaped spreader 1210 may have internal threads 1230, which enables the lid to securely attach to the top of the bottle by screwing it on, snapping it on, or alternatively by affixing it by any other mechanism or instrumentality.
Referring to FIGS. 33a and 33b, the orifice's dome-shaped spreader 1220 may have slits 1229 or a plurality of cross-slits 1231 instead of fully open apertures or orifices. It is to be appreciated that the holes where the product emerges, can have a plurality of diameters or shapes and any geometric configuration.
Referring to FIGS. 34a and 34b, an embodiment is illustrated in which the dome-shaped spreader/applicator 1210 is placed within the inside lip of the bottle 1240. The spreader/applicator is held in place by a number of mechanisms, including threads or snaps. The dome in this embodiment fits proximate to the bottle top and has an annular serrated ridge 1354 which fits on the inside of the bottle. The dome can also be screwed into the bottle or secured using a variety of mechanical attachment systems.
FIGS. 35a-35e illustrate caps 1300 which fit over the dome-shaped spreader. The present invention displays a number of cap embodiments. As shown in FIG. 35a, a first cap embodiment comprises a dome-shaped nozzle cap which is attached by a living hinge 1318. It can also be separate from the bottle. As shown in FIG. 35e, the cap can comprise a male closure with matching prongs 1323 which cover over the orifices. This prevents clogging of the holes by dried product.
FIGS. 36a to 36c illustrate an embodiment of the dome-shaped nozzle applicator 1360 which corresponds to the wide flange embodiment of FIG. 30. Here the oval-shaped applicator 1360 is dome-shaped and a corresponding cap is dome-shaped and is designed to fit on the bottle. The dome can fit inside or outside of the bottle as shown in FIGURES. Alternatively, the dome-shaped applicator 1360 can have slits, crosses or other aperture shapes 1362 as shown in FIG. 36c. 
FIGS. 37(a)-(f) illustrates yet a further embodiment of the present invention. In this embodiment the dome-shaped applicator has a rotating dial cover 1372 which permits the apertures or orifices 1220 to be selectively opened and closed. By rotating the dial in one direction the orifices are open and product can flow. When rotated in the other direction the orifices 1220 are closed. The orifices can have any shape, size or configuration.
FIG. 38 illustrates a dome having a plurality of orifices having different shapes, sizes and orientation. The different sized orifices 1220 allow the passage of different sized chunks or pieces (e.g. “Thousand Island” salad dressing).
FIG. 39 illustrates yet another embodiment of the invention in which the applicator has the shape of a flattened, four sided pyramid 1380 instead of a curved shape. Each side 1382 has a plurality of orifices 1384. It is to be noted that the pyramid embodiment can have more than four sides (e.g. 6,8, 10, etc.). The invention also suggests additional embodiments besides pyramid shapes.
FIG. 40 is an embodiment which corresponds with the nozzle embodiment of FIG. 28. In this embodiment, the dome-shaped applicator is affixed to the end of the cylindrical nozzle casing and permits product to flow through the orifices 1220.
Referring to FIGS. 41a to 41c, alternative orifice configurations are shown. The orifices can be indented 1390 into the bottle. They can also face or protrude outward 1394. They can be contiguous with the dome 1396. The strength and pliability of the plastic, impacts the types of food to be used and the amount of pressure that needs to be applied.
Referring now to FIGS. 42a and 42b, a still further embodiment is shown and described. This embodiment comprises an applicator with a plurality of nipple openings 1400. The embodiment comprises a plurality of flexible nipple inserts 1410. The flexible nipple inserts 1410 are indented inwardly 1420 into the bottle and they are forced outwardly 1425 when the product is squeezed out.
FIGS. 43a to 43e shows a number of dome-shaped embodiments which illustrate the use of nipples. The nipples are shown as having a cross or X-shaped orifices 1500 as well as slits 1510. The nipple embodiment can be utilized with any of the embodiments shown in FIGS. 1 to 31.
FIG. 44 illustrates an embodiment of the present invention in which the orifices are angled 1520. This embodiment permits product to be dispensed in a wide variety of directions.
Finally, FIGS. 45a and 45b illustrate another embodiment in which the applicator 1600 has two sets of orifices. A four-holed dial 1610 can then be rotationally affixed over the applicator 1620. When the dial is turned in a first direction, the large orifices 1630 align with the dial. When turned in a second direction, the small orifices 1635 align. A third position closes the orifices. This embodiment facilitates two levels of product application flow.
While the preferred embodiment of the present invention has been described and illustrated, modifications may be made by one of ordinary skill in the art without departing from the scope and spirit of the invention as defined in the appended claims. For example, in a preferred embodiment of the present invention, the bags 410 and 540 may be polybags, however, the bags may be of any type known to one of ordinary skill in art. Additionally, the method of securing the nozzles to the containers has been described and illustrated as being via a threaded engagement. However, a skilled artisan may employ any appropriate means to attach the nozzles to the containers, such as, but not limited to, a snap connection or molded piece.
In addition, while the invention has been principally described in the context of food, it is to be appreciated that the applicator and spreader of the present invention may be applicable to non-food products. Nonexclusive examples include caulks, pastes, glues and building materials and automotive products such as waxes, greases, etc.
