BACKGROUND OF THE INVENTION Field of the Invention 0005 The present invention relates to carrying bags and in particular to soft-sided hot cold diaper bag having a carrying strap and three Zippered compartments, a first insulated warming compartment, a second insulated cooler compartment and a third storage compartment located between the cooler and warming compartments for items Such as diapers, clothing and toys; the bag is provided with heating packs and cooling packs to be wrapped about a container such as a baby bottle Description of Related Art Including Informa tion Disclosed Under 37 CFR 1.97 and ) A number of diaper bags are known. Most attempt to address the issue of carrying the numerous items that may assist those involved in the diaper changing process, such as food, clothing and toys. Few address the need to warm a baby bottle or maintain the coolness of a bottle One Step Ahead advertises a travel baby bottle warming device which uses a hydrated salt solution heating pad to wrap and warm the bottle. The pack may be reused and is recharged by boiling and cooling the heating pad U.S. Pat. No. 5,318,107, issued Jun. 7, 1994 to Bell, shows a carrying bag that has a frame of rigid pieces Secured together in three-dimensional shape, and panels are secured thereto forming a bottom side wall, end wall, and a pair of top closure panels, the latter being angled forming a gable roof type top. The panels are of limited flexibility enabling them to be bent about long radii. Abottle cooler and an electric warmer are provided, a large central space accommodating a large quantity of diapers forming great heat insulation between the bottle cooler and bottle warmer. The bottle warmer includes and electric cord normally held in a pocket and extendible to the exterior for plugging into a house socket or cigar heater socket in an automobile. The top panels have small sections that can be opened without opening the complete top panels enabling the bottles to be withdrawn and inserted vertically. A changing pad made up of hinged panels is secured to the interior, and is operable to a spread position for lying on a supporting surface, and foldable into a pack that is positionable flat against a side panel and normally held there U.S. Patent Application # , published Jun. 24, 2004 by Karlsson, claims a substantially tubular carrying case, wherein the tube is sectioned into multiple Substantially separated transverse compartments for carry ing personal items. In one embodiment, the carrying case looks like a golf bag. In another embodiment, the carrying case is a diaper bag. One or more portions of the main body may optionally comprise an insulating material so that the contents of one or more compartments can insulated from undesirable temperatures. In the case where a cool tempera ture is desired, a cooling pack may be added to the insulated compartments. When warm temperatures are desired, a hot pack may be added to the insulated compartments Three U.S. Pat. Nos. 6,705,108 issued Mar. 16, 2004, No. 6, issued Jan. 14, 2003, and No. 6,427, 475 issued to Aug. 6, 2002 all to Defelice, are for a nested cooler system for temporary storage of perishable food stuffs and more particularly to articles for convenient, temporary storage of human breast milk and infant formulas. The inner and outer coolers jointly or independently receive the per ishable foodstuffs and freezable gel packs for cooling the perishable foodstuffs. The gel packs can be frozen and thawed several times and temporarily keep containers of milk within an acceptable temperature range to prevent spoilage. The gel packs fit within pockets in the coolers to maintain proper positioning of the gel packs relative to the bottles U.S. Pat. No. 5,711,164, issued Jan. 27, 1998 to Slack, provides a portable cooler including a plastic bag or container with inflatable sidewalls into which are placed items for cooling, such as infant feeding bottles, food, soft drinks, etc. Prior to using these items, the sidewalls of the bag are inflated with CO. Sub.2 gas, which upon expansion, sufficiently cools the interior of the bag, and chills the food. The plastic bag may also contain a frozen gel package to provide temporary cooling prior to use, and augment cooling by the CO. Sub.2. In a similar manner, cooling may be provided using a relatively stiff container having hollow sidewalls and/or a bottom into which may be expanded CO. Sub.2 gas to provide cooling prior to use. A frozen gel package may be placed inside the container or in the top portion of the container to augment CO. Sub.2 gas cooling. The same technique of cooling may also be accomplished using the expansion of CO. Sub.2 gas into the sidewalls of a thermos container. Another embodiment of this invention comprises a diaper bag having a rigid or resilient foam plastic container portion providing diaper bag's baby bottle outer pockets which are used to contain baby bottles. An intake Valve leads into the dead air spaces adjacent the pockets, and enables CO. Sub.2 gas to be fed therethrough, expand and cool bottles held in the pockets. A top flap is secured to the container and is closed by VELCRO.T.M. strips; the flap closure will secure and insulate the bottles: a carrying strap is also provided U.S. Pat. No. 5,234,143, issued Aug. 10, 1993 to Mahvi, indicates a multipurpose traveling bag for carrying personal items and/or infant care supplies comprising a primary bag section and a removable auxiliary bag section.

DETAILED DESCRIPTION OF THE INVENTION In FIG. 1, a multifunction diaper storage bag 20 comprises a carrying bag 21 that has an outer casing housing three separate compartments 22, 23, 24 therein with a separate access opening for each compartment and a closure means for each opening, preferably a Zipper 26 across the entire length of each opening, and a means for carrying the bag, preferably a shoulder Strap 25 attached to two opposing ends of the carrying bag The first compartment 22 of the three compart ments is located on one side of the storage bag. It comprises a cooling compartment that has thermal insulation in at least an outer wall 11 of the cooling compartment and at least one cooling pack 27 or cold pack positioned in the cooling compartment 22. In FIGS. 2 and 3, the cooling pack 27 contains a quantity of pre-cooled liquid 14 So that the cooling pack cools items including baby food and drink containers, such as a baby bottle 30 or jar of baby food stored within the cooling compartment without the need for an external power source In a preferred embodiment, as shown in FIGS. 2, 3, and 4, the cooling pack 27 comprises at least one pair of cooling packs positioned with one on each side of an item to be cooled, such as a baby bottle 30 or jar of baby food inside the cooling compartment The second compartment 24 of the three compart ments is located on the opposite side of the storage bag 21 from the cooling compartment 22. The second compartment comprises a warming compartment with thermal insulation in at least an outer wall of the warming compartment similar to the cooling compartment and at least one heating pack 29 or 29A positioned in the warming compartment. In FIGS. 5 and 6, the heating packs contain a quantity of a Super saturated Solution 16 of Sodium acetate and a stainless steel disc 17 so that bending the stainless steel disc activates a chain reaction to crystallize the Sodium acetate solution to generate heat so that the heating pack heats items including

8 baby food and drink containers stored within the heating compartment without a need for an external power source In FIGS. 5, 6A and 8, the heating pack 29 com prises at least one elongated heating pack encircling an item to be heated, such as a baby bottle 30, and a means for securing the elongated heating pack around the item to be heated, preferably snaps 18 placed on end flaps 15 of the heating pack 29. In FIGS. 6B, 7, and 9, a pair of heating packs 29A are secured around an item such as a baby bottle 30 or baby food jars preferably by a strap 28 with mating hook and loop fastener tabs 19A and 19B at each end. 0054) In FIG. 1, in a preferred embodiment, the outer wall 11 of the cooling compartment 22 and the outer wall 11 of the warming compartment 24 each comprise an insulated foil lining for thermal insulation, and the inner walls 12 between the third compartment 23 and the first and second compartments 22 and 24 may each comprise an insulated foil lining for thermal insulation The third compartment 23 of the three compart ments is positioned between the first compartment 22 and the second compartment 24 and separated by an inner wall 12 between the third compartment and each of the other compartments. The third compartment comprises a storage compartment for storing an assortment of baby-related items including diapers 40 and baby clothing items 41, wipes 42, and a blanket 43. The third compartment and the stored assortment of baby-related items therein creates a thermal insulation barrier between the first compartment and the second compartment In use, bottles of milk or baby food jars can be kept cool for hours with the use of cooling packs. The cooling packs are placed along with a bottle of milk or baby food jar inside the insulated cooling compartment on one side of the bag. The insulated cooling compartment helps keep the cooling pack and the food and drink containers cold. The cooling packs contain a frozen liquid 14 which melts during usage and can be refrozen in a freezer and reused repeatedly Abottle of milk or baby food jar can be warmed up by securing the heating packs around the bottle or baby food jar with the snaps 18 on the end tabs 15 of the elongated heating pack 29 or the pair of shorter heating packs secured by a strap 28. The heating packs are activated by flexing the stainless steel disc 17. Flexing the disk causes a chain reaction that forces the liquid to begin to crystallize, which produces heat. The temperature of the Solidifying liquid quickly reaches 130 degrees Fahrenheit or 54 degrees Cen tigrade. Once activated, the heating packs that are wrapped around the bottle or jar of baby food will immediately begin to heat up. The user places the heating pack wrapped bottle inside the warming compartment for minutes. The pack will be very hot for the first 30 minutes and then will gradually cool down Once the heating pack has given off all of its heat it will remain in its crystallized state until it is recharged. To recharge the heating pack, the user places the crystallized pack in boiling water for 5 to 10 minutes, depending upon the size of the pack, until all of the crystals are melted. Once completely liquefied, the user removes the pack from the water and store it until it is needed. The pack should remain liquid as it cools. If crystals form as the pad cools, it has not been boiled long enough and should be placed in boiling water again until all the crystals have dissolved and the pack is completely clear. There is no limit as to the number of times a pack can be used. The heating pack can also be used for added body warmth on a cold day, or for therapeutic heat for an injury Between the cooling compartment and the heating compartment, the center storage compartment of the bag holds items such as diapers, wipes, clothes, and blankets, which act as insulation between the cooling compartment and the heating compartment It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and that various modifications may be made thereto without departing from the spirit of the invention as claimed.
