Definitions
- This invention concerns an isothermal bag keeping the temperature of food and beverages inside even.
- thermoses thermoses
- portable coolers thermos flasks
- Thermoses are usually cumbersome and carrying them causes inconvenience once the drink is finished.
- Portable coolers which are made cold by artificial ice
- Thermos flasks are light but cumbersome, too.
- thermos flasks are only used when users carry both drinks and foodstuffs, thus accepting all the inconvenience related to their weight and dimensions.
- 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. Indeed, users need to open and close the bag every time they want to drink, the which is uncomfortable and increases heat exchange between the inside and the outside.
- 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.
- the bag is closed by a string and is therefore vulnerable to dust, sand and other unhygienic conditions implying higher manufacturing costs.
- 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.
- 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. 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.
- the bag may have just one hole on the closed shorter side.
- 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.
- 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.
- 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 contact 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.
- - 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;
- FIG. 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
- FIG. 6 shows a frontal view of the bag manufactured according to a third embodiment.
- 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, 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
- 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.
- the flap 2 is folded until it completely covers the upper part of the bottle 4.
- 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.
- 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 1 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.
- the open shorter side 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.
- the bag 1 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.
