-1- Isothermal bag for bottles and foodstuffs.

Technical field This invention concerns an isothermal bag keeping the temperature of food and beverages inside even.

Background Art People often feel like having cool food or drinks water, tea, wine, soft drinks etc) within their reach especially when the weather is hot and no fridge is available, such as when they are on the beach, on a tennis court or during long journeys.

Today there are several systems to keep food and drinks cool without using a fridge, as widely known. These systems include thermoses, portable coolers and thermos flasks, which may however have some minor or major drawbacks for users. Thermoses are usually cumbersome and carrying them causes inconvenience once the drink is finished. Portable coolers (which are made cold by artificial ice) are cumbersome and heavy to carry. Thermos flasks are light but cumbersome, too. Therefore portable coolers and thermos flasks are only used when users carry both drinks and foodstuffs, thus accepting all the inconvenience related to their weight and dimensions.

But people often wish to have just one cool drink or some food kept in a small box or bowl yoghurt, ice-cream, a sandwich etc.) within their reach, in which case they do not carry anyone of the above-mentioned cooling systems because of their inconveniences. Therefore, food and drinks become warm and unappetising after a short period of time, especially if they are under the sun.

Several solution have been developed to solve this problem. For example the US Patent N. 4,211,091 describes a flexible insulated lunch bag adapted for transportation and storage of food but not specific for bottles. The fastening of the bag is obtained by tape fastener. Nevertheless to close perfectly the bag the bottle must to be totally inside the bag itself. Indeed, users need to open and close the bag every time they want to drink, the which is uncomfortable I AMENDED SHEET 21-05-2002' Pinted:05-1 1-2002 DESPAMD 01 983780-1T0100539

1Aand increases heat exchange between the inside and the outside. The claimed bag besides requires a flexible carrying strap which allows to carry the bag both full and empty. This strap is fastened on the bag by a detachable bond which is vulnerable by the dust and by the sand, and it emplies higher production costs and manufacturing problems.

The US Patent N. 4,669,632 describes a bag as well provided with two gas impermeable films but without the specific opening studied for the bottles.

Another solution consists in using specific bags for bottles, such as those described in U.S. Patents N. Des 403,926 and N. 5,890,809. However, these containers do not cover the bottle completely and reduce heat insulation. U.S.

Patents N. Des 409,450 and N. 5,804,265 make reference to some other bags for bottles, which actually do cover bottles completely, but have no hole to drink directly from them. In this case as well, as described for the US Patent N. 4,211,091, users need to open and close the bag every time they want to drink with the consequent inflow of warm air and what it means.

U.S. Patent N. Des 392,025 gives a rather effective solution because the bag covers the bottle up to its neck, thus enabling users to open the stopper without opening the bag too. Unfortunately though, the bag is closed by a string and is therefore vulnerable to dust, sand and other unhygienic conditions implying higher manufacturing costs. It happens the same for the NL Patent N. 1001720 which describes a bag with a string totally surrounding its open side with the above menthioned inconveniences.

Another known patent is the European Patent N. 0710608 which describes an insulated carrying container formed of multiwall flexible plastic heat sealed.

The two-ply carrying portion have a pair of attachment flaps, each of which has a central aperture and which is separated from the handle portion by a cut. The attachment flaps are sequentially folded over the mounth of the bottle. But the two attachment flaps have such shape and size which do not let the complete covering of the bottle. On the contrary, two hollows on the longer sides of the bag let the warm air inflow producing two air spaces which AMENDED SHEET 21 -05-2002

-2warms the sides of the botlle up for it s all lenght. Furthermore, the constant presence of the carring handle is an obstacle while drinking.

Summary of the invention This invention aims at providing users with a new a new isothermal bag, which can keep food or drink temperature even and does not have the same inconvenience as the above-mentioned cooling systems.

These goals are achieved by this flexible, isothermal and pocket-size bag. It is made by folding a rectangular foil in two which is then fixed by two sides joined by welding or any other method. The final product is a bag with just one opening on the shorter side. The opening is delimited by two flaps each of which has a hole that is approximately the same size as a bottle neck. The holes are located near the edges of the open shorter side. The edges of each hole may be elasticised or reinforced by welding or rings made up of different materials. The two holes are approximately coaxial.

The bag is approximately the same size as a bottle, so that the bag can perfectly wrap it up.

The foil is made up of three different layers of soft and flexible synthetic materials which are specifically used for foodstuffs. The external layer is reflective, the intermediate one has thermal-insulation characteristics and the internal one is waterproof and/or reflective. The foil may also be made up of four layers, in which case the external layer is reflective, the two intermediate ones have thermal-insulation characteristics, whereas the internal one is waterproof and/or reflective. It is also possible to use a foil with one single layer featuring thermal-insulation, waterproof and reflective characteristics.

The isothermal bag may have round corners and its bottom may be folded.

AMENDED SHEET 12105-2002 WO 02/34644 PCT/IT01/00539 -3- An elastic band, a string or a ribbon may be fixed outside the bag, which may be rolled up or folded up before or after being used so as to become compact and pocket-size. The elastic band, the string or the ribbon keep the bag rolled or folded and prevent it from spreading out again.

An alternative solution is given by another hole on the closed shorter side, which is approximately the same size as a bottle neck, too. As an alternative, the bag may have just one hole on the closed shorter side. In this case, the edges of the shorter side can be provided with a closing device such as a minigrip or a handle.

The bag can also be made by joining two rectangular foils, which are fixed together along three sides, that is the two longer sides and the shorter one.

This isothermal bag has many of the advantages offered by other cooling systems but does not have their drawbacks. Indeed, it is handy and very light, it may be used again, it is hard to break, easy to carry and user-friendly.

It is a pocket-size bag and can therefore be put away very easily and with very little encumbrance.

Its weight is extremely low as the materials used are very light. However, although the materials are very light they are extremely resistant, so resistant that the bag can be used several times. On the other hand, the bag is very cheap and users can throw it away after using it just one single time.

The holes on the bag may also be used as a handle so that users can easily carry the bottle by holding it with one finger.

Unlike usual thermal bags, this one wraps up bottles completely thus increasing heat insulation. Its holes enable users to drink straight from the bottle without opening and closing the bag every time they want to drink, thus reducing heat exchange between the inside and the outside. Its closing device is easy, functional and hygienic at the same time.

One of the main advantages of this bag lies in its hygienic characteristics.

Indeed, it is made up of waterproof materials which are specifically used for food and drinks. Condensation (which is produced when cold bottles get in WO 02/34644 PCT/IT01/00539 -4contact with warm air) is pretty much reduced by this invention, so that the bag can avoid unhygienic mixing between condensation and the materials (such as sand, seaweed, red earth, dust etc.) located on the surface where the bottle is placed. This way, users can avoid dirtying their hands or the container where the isothermal bag is placed, such as handbags, belt bags, rucksacks etc. Moreover, the bag can easily be washed as it is made up of waterproof materials.

Brief Description of Drawings Further characteristics and advantages of the invention will be clarified in the description of some particular kind of embodiments of the above mentioned bag, which are preferable but not compulsory and are given for explanatory purposes only in the enclosed drawings, in which: figure 1 shows a frontal view of the bag manufactured according to a first embodiment; figure 2 shows a frontal view of the bag when the first flap wraps up the neck and the upper part of the bottle; figure 3 shows a frontal view of the bag when both flaps wrap up the neck and the upper part of the bottle; figure 4 shows a perspective view of the bag when it is rolled up; figure 5 shows a frontal view of the bag manufactured according to a second embodiment; figure 6 shows a frontal view of the bag manufactured according to a third embodiment.

Best Mode for Carrying Out the Invention The isothermal bag 1 manufactured according to a first embodiment is made by folding a rectangular foil in two along the shorter side, which is then joined by welding the two longer sides. The final product is a bag with just one opening on the second shorter side. The opening is delimited by two flaps 2, 3. Each flap 2, 3 has a hole 2.1, 3.1 whose size is approximately the same size as a bottle neck 4. The holes 2.1, 3.1 are located near the edges 2.2, WO 02/34644 PCT/IT01/00539 3.2 of the open shorter side.

The dimensions of the bag 1 are approximately the same as those of the bottle 4.

The rectangular foil is made up of three different layers of soft and flexible synthetic materials which are specifically used for foodstuffs, such as PET.

The external layer is reflective, the intermediate one has thermal-insulation characteristics and the internal one is waterproof and/or reflective.

If the temperature of a bottle of cold water 4 is to be kept even as long as possible, even under the sun, the bottle is inserted into the isothermal bag 1.

Thanks to its size, the bag 1 is like a case perfectly and completely wrapping up the bottle 4.

The hole 2.1 of the first flap 2 has to coincide with the end of the bottle neck 4. The bottle neck is put inside the hole 2.1. Then the flap 2 is folded until it completely covers the upper part of the bottle 4. Now, the hole 3.1 of the second flap 3 has to coincide with the end of the bottle neck 4.The bottle neck is put inside the second hole 3.1, too. Then the second flap 3 is folded until it completely covers the first flap 2. Consequently, the upper part of the bottle 4 is completely covered by the bag 1 and it still is possible to drink from it without opening the flaps 2, 3 again as the bottle neck comes out of the two holes 2.1, 3.1.

The two flaps 2, 3 cannot be lifted as the edges of the two holes 2.1, 3.1 are stuck on the bottle neck 4.

The isothermal bag I manufactured according to a second embodiment also has a closed shorter side with a hole 5, which is approximately the same size as the bottle neck 4. In that case, the bottle 4 is to be inserted into the bag 1 and its neck is to pass through the hole 5. The two holes 2.1, 3.1 serve as handles to carry the bag 1 and the bottle 4 inside it.

The isothermal bag 1 manufactured according to a third embodiment does not have any holes 2.1, 3.1 on its open shorter side, whereas the closed shorter side has the above-mentioned hole 5. In that case, the open shorter WO 02/34644 PCT/IT01/00539 -6side is provided with a closing device such as a minigrip 6 and a handle 7 to carry the bag 1 and the bottle 4 inside it.

The bag 1 is made up of very light materials so that users do not feel its weight while carrying the bottle 4. However, the characteristics of its materials allow to keep the temperature of the liquid inside the bottle 4 even in extremely hygienic conditions.

Once the bag 1 has been used, it can be rolled up so that it becomes compact and pocket-size. The string 8 prevents the bag 1 from spreading out again.
