The invention relates to a small, pocket-sized, multi-functional and reusable double-wall isothermal small bag for easier transportation and storage of temperature-sensitive, light-sensitive drugs such as ophthalmic and other drugs, as well as other small objects.

To this day, large-sized bags are already known and used for the isothermal transport especially of perishable, solid food products and other products such as pharmacological, cosmetic, microbiological and which consist only of polymer membrane walls and insulators having different closing/opening systems. Such voluminous bags, precisely because of their large dimensions, but also because of the lack of cooling/heating elements on the walls necessary to maintain the appropriate temperature state of their contents, are totally unsuitable for use in the transport, storage and use of objects small-sized pharmacological products or a small number of objects such as single-dose vials, vials, ampoules, ophthalmic wipes and other small objects that must be kept during their use at a certain temperature, usually below 25° C, so that this content to remain active and sterile until it is exhausted.

As is well known in the treatment of eye diseases, it is necessary to frequently administer eye drops either from the same medicine or alternately with other medicines. So, in everyday practice, most of the times it is observed the non-compliance with the prescribed therapy both by adults and especially by young people, because apart from other difficulties, there was no i

there is no easy-to-use bag on the market for carrying and storing the above-mentioned drugs. Thus, the lack of a suitable bag contributes decisively to not carrying out the prescribed therapy correctly, which has the effect of prolonging its duration and increasing its cost.

The advantages of this invention are:

a) The small double-wall isothermal bag, due to its small dimensions, is very easy to transport and facilitates the access and use of small pharmacological objects carried in it, which are extremely necessary in oculistic treatment or in other types of therapy. This advantage among others makes it possible to carry out the prescribed therapy correctly or to use the contact lenses correctly in places outside the home, such as at work, in places of entertainment, restaurants, in sports activities, in means of transport, etc.

b) The small double-wall isothermal bag, maintaining the preset maintenance temperature, keeps the active pharmaceutical substances unaltered and sterile throughout their use, and in this way the prescribed treatment is applied correctly, effectively and economically

c) The small double-wall isothermal bag, maintaining the preset maintenance temperature, keeps the active pharmaceutical substances unaltered and sterile throughout their use and allows the full use of the contents of single-dose vials, ampoules and other small objects, again contributing to reducing the cost of treatment .

d) in the small isothermal bag with a double wall, the contents of the objects stored in it are kept sterile, even after the first opening, for example, of the single-dose bottle, preventing the loss of its protective cover and in this way any contamination is avoided, which would increase the duration and cost of treatment.

, »

e) two removable bags with cold/warm thermal gel are placed in the small isothermal double-walled bag, with the help of which cryotherapy or thermotherapy can be performed outside the home on different parts of the human body, e.g. cold compresses in the periocular area with cryogenic action for decongestion due to various causes such as lack of sleep or the presence of allergies, etc. or warm compresses for the treatment of blepharitis, stye (pitcher), chalazion and other pathologies. The removable bags with cold/warm thermal gel have a characteristic ellipsoidal shape so that they fit correctly in the periocular area, but also on other parts of the body, especially in children, for local treatments e.g. bruises, contusions in the small joints of the upper and lower limbs, but also in other areas.

f) The small double-wall isothermal bag is used both outside and inside the house. in the first case to cope with high ambient temperatures, and in the second case to protect light-sensitive pharmacological substances such as glaucoma drugs, corticosteroids and other drugs.

g) The small isothermal bag with a double wall as a unitary whole has two isothermal walls, each of which presents independent cooling systems, both of which contribute to ensuring the most suitable temperature for a longer period of time, with the aim of maintaining the most correct pharmacological substances and other small objects.

h) The small isothermal bag with double wall will be made of resistant and low-cost materials, so that it has a long durability and a low commercial value to be accessible to as many users as possible.

DISCLOSURE OF THE INVENTION

Starting from the mentioned bags, which are already on the market and are used in the isothermal transport of medicines and other products, but which do not satisfy the needs we have spoken about because they do not present the advantageous characteristics of the present invention in accordance with which it is proposed to make a small, multi-functional, multi-layered and reusable double-wall isothermal bag of small size, pocket type, for carrying and keeping safe especially single-dose ophthalmic vials, vials, ampoules, ophthalmic wipes and other small medical items, which need to be maintained throughout their use at a certain temperature, so that their content remains active and sterile until it is used up, avoiding its contamination. This is also achieved by correctly positioning the protective cover without the risk of it being lost or detached during transport.

The small double-wall isothermal bag according to the invention consists of two bags independent of each other, an internal bag with a permanently cold thermal gel bag embedded in it and an external bag which surrounds it, and together they contribute by their independent cooling elements to maintaining the cooling capacity of the entire bag for as long as possible. The dimensions of the internal bag with the built-in permanent cold thermal gel bag are slightly smaller than the dimensions of the external bag, so the small double-wall isothermal bag as a whole occupies the minimum possible space. The wall of the internal bag is multi-layered, consisting of a permanent cold thermal gel bag embedded and subdivided into compartments, which is surrounded in the form of a "sandwich" on the inside by a layer of absorbent material and a waterproof membrane, and on the outside by a layer made of absorbent material and a heat-insulating and waterproof membrane. Each wall of the external bag is single-layered and made of heat-insulating and waterproof material, with mesh pockets on the inner surfaces, in which the removable bags with cold/warm thermal gel are placed. When the owner of the bag carries it in his pocket or holds it in his hand, the external bag has the role of reducing the transmission of the user's body heat to the internal bag with the cold thermal gel bag, where the pharmacological objects are placed for transport and therefore on the one hand the capacity the cooling effect is maintained as much as possible for as long as possible, and on the other hand it avoids that the user has unpleasant sensations following the direct contact of the body with the cold surface of the internal bag.

In order to better understand this invention, the separate parts of the bag are shown below, which when assembled together give the final appearance of the small insulated double wall bag.

The above illustrated drawings of the small insulated double wall bag are not limiting in terms of dimensions, methods of manufacture, materials, shape or other factors and are used only to understand the invention. in this way, the possibility of making other variants of the present invention is offered.

Figure 1 shows the multi-functional, multi-start and reusable double-wall isothermal small bag which consists of the outer bag (10) and the inner bag with the cold thermal gel bag (20) drawn in broken lines. The outer bag (10) surrounds the inner bag with the cold thermal gel bag (20) which is slightly smaller than the outer bag (10), carries on the inner surface the removable cold/warm thermal gel bag (16'J placed in the pocket mesh (15') which is also represented by broken lines and shows the side seams (18,18').The above mentioned bags are independent of each other and can be used either together in one set or independently of each other.

Figure 2 shows the outer bag (10) in the open position, where the front is numbered (11) and the rear is numbered (12). The external bag (10) consists of a single layer of flexible, resistant, heat-insulating and impermeable material, preferably textile. This bag when opened is equipped with a closing/opening system consisting of two strips (13,13') for interconnecting the assembly component parts, preferably of the Velcro type, through which the strip (13) is fixed to the rear wall ( 12) by means of the double seam (17), and the other strip (13'), which is not visible in the drawing, is fixed to the front wall (11) by means of the double seam (17'). The strips (13, 13') of the closing/opening system come into contact with each other, and by applying an external pressure, the tight interconnection of their component assembly parts is achieved, creating a hermetically sealed storage space (19). in this space is inserted the internal bag with the bag with cold thermal gel (20), which is not visible in this Figure 2 and which borders the internal surface of the external bag (10) where the removable bags with cold/warm thermal gel are found ( 16,16'). One removable cold/warm thermal gel pouch (16) is located in the mesh pocket (15) located on the inner surface of the back wall (12) of the outer bag (10), and the other removable cold/warm thermal gel pouch (16') is found in the mesh pocket (15') which is on the inner surface of the front wall (11) of the same bag and appears in this Figure 2 with broken lines. The Cold/Warm Thermal Gel Detachable Bag (16') although identical to the Cold/Warm Thermal Gel Detachable Bag (16), however they are not identified by the same numbering for clearer understanding of the drawing. For easier opening of the bag, the specially designed opening protrusions (14,14') are pulled in opposite directions and thus the closing/opening system is activated. These opening protrusions (14, 14') are either manufactured from later added materials or are continuous parts of the outer bag walls (10). The front wall (11) of the external bag (10) is sewn to the rear wall (12) of the same bag on both sides by the side seams (18, 18') which also appear in Figure 1.

Figure 3 shows the rectangular sheet of material needed to make the outer bag (10) in plan view and further to make the bag, it is folded along the folding line (21), and by folding it forms the front wall (11) and the back wall ( 12) of the outer bag (10), walls sewn through the side seams (18, 18'), which are not visible in Figure 3, thus creating a U-shaped bag. On the narrow sides of the material sheet for making the outer bag (10) the opening protrusions (14, 14') are provided for this purpose to facilitate the activation of the closing/opening system, which consists of the two strips (13,13') of the steep interconnection of the assembly component parts, preferably of be Velcro type. The empty bag, without the removable cold/warm thermal gel pouches (16.16'') which are not visible in this drawing, takes a square shape, with a small thickness thus presenting the advantage of occupying a very limited space for custody. Mesh pockets (15, 15') are attached to each inner side of the outer bag walls (10). The above arrangement maximizes the cooling efficiency of the detachable cold/warm thermal gel pouches (16.16') to the overall cooling capacity of the small double wall isothermal bag.

Figure 4 shows the ellipsoidal shaped removable cold/warm thermal gel pouch (16) containing the non-toxic biodegradable cooling/warming gel (23) sandwiched between two durable plastic membranes as a cooling/warming medium. These membranes are hot-glued together by means of a peripheral strip (22) of small width. The ellipsoidal shape of the detachable cold/warm thermal gel bag (16) on the one hand helps to maintain the temperature in the small double-wall isothermal bag, and on the other hand, it can be applied to the affected areas of the human body for various local treatments, but only after being placed in a protective cover (161), which is not shown in the drawing.

Figure 5 shows the C-C section shown in Figure 4 of the detachable cold/warm thermal gel bag (16) and showing the space for positioning the biodegradable, non-toxic cooling/warming gel (23) and the peripheral band (22).

Figure 6 shows the protective cover (161) of the detachable cold/warm thermal gel bag (16) into which it is inserted after being removed from the bag to be applied in various local treatments to the affected areas of the human body.

Figure 7 shows from the front the internal bag with the cold thermal gel bag (20) which can be removed from the external bag (10), which is not visible in the present drawing and can be continuously cooled so that it is ready for use at any time . The internal bag with cold thermal gel bag (20) is the main thermal cooling element of the invention, which contains the main storage space (19') for carrying small pharmacological objects or other products, which space is not illustrated in this drawing. For the transport of the above-mentioned objects, the internal bag with the cold thermal gel bag (20) can be used either alone or together with the external bag (10) so that a longer period of time is obtained to maintain the required temperature. Due to the fact that the front wall (11') of the internal bag with the cold thermal gel bag (20) is multi-layered, in this Figure 7 we only see the outer heat-insulating and impermeable membrane (24) with a metallic appearance surrounding it. This membrane, apart from its insulating properties, also offers the possibility of writing on its outer surface instructions for the use of small stored pharmacological objects or other important information to be known. The front wall (11') of the inner bag with the cold thermal gel bag (20) along the axis (2T) is continuous without interruption of the fabric with the back wall (12'), which is not seen in Figure 7 and both walls present the lateral adhesive strips (30, 30'), and on their open side they are provided with two auxiliary opening strips (33, 33') hot-glued and based on the elements: (28), not visible in the present drawing and (28') of the closing/opening system, preferably double ziplock type. These elements (28, 28') of the closing/opening system have a linear poeminence and a recess in the form of a groove, which it penetrates when in the position to be closed and in the form of which their joint is created. The use of a double ziplock closure/opening system is required for a tight closure of the bag. Only on one side of the extreme area of one of the auxiliary opening strips (33, 33') is a notch (29) provided to facilitate the opening of the preferably double ziplock closing/opening system. This makes it easy and quick to position pharmaceutical items and other small items in the central area of the internal bag with the cold thermal gel bag (20), which is actually the main storage space (19') for these items, but which is not see in this illustration.

Figure 8 shows the perspective sketch of the layers from which the sheet of material is made to make the inner bag with the cold thermal gel bag (20). The walls of the internal bag with the cold thermal gel bag (20) are multi-layered and made of 5 different materials, which from the outside to the inside are:

1. the thermally insulating and waterproof outer membrane (24) coated on the outside with a reflective metallic material to reflect external thermal radiation when the inner bag with the cold thermal gel bag (20) is used alone

2. absorbent layer (25) for absorbing moisture that can form during periods of freezing and thawing (liquefaction-evaporation) inside the walls of the internal bag with the cold thermal gel bag (20) io

3. the compartmentalized cold thermal gel bag (26) which is permanently embedded in the sheet of material making the walls of the internal cold thermal gel bag (20)

4. absorbent layer (25) for absorbing moisture that can form during periods of freezing and thawing (liquefaction-evaporation) inside the walls of the internal bag with the cold thermal gel bag (20)

5. the biodegradable, non-toxic waterproof membrane (27) surrounding the small pharmacological items and the other items carried in the double-wall isothermal small bag. The waterproof membrane (27) is transparent to easily observe any gel losses on the walls of the inner bag with cold thermal gel bag (20) caused by incorrect use or perforation of the compartmentalized cold thermal gel bag (26) and therefore this inner bag with cold thermal gel bag (20) must be replaced immediately.

The compartmentalized cold thermal gel bag (26) consists of the biodegradable, non-toxic cooling gel (23') or water or other environmentally friendly cooling agent and is encased by two strong plastic membranes, joined together by heat-sealing around the perimeter , presenting horizontal and vertical adhesive strips (31) so as to create alveolar compartments or any other shape, which contributes to the uniform distribution of the cooling agent along the walls of the internal bag with the cold thermal gel bag (20) and thus it does not they accumulate at their base due to gravity, and so the entire internal bag with the cold thermal gel bag (20) on its assembly shows sufficient flexibility even when frozen. The compartmentalized cold thermal gel bag (26) is the cooling device of the internal cold thermal gel bag (20) and as it is embedded and tightly sealed between the constructive layers of its walls, it provides the cooling energy to the main storage space ( 19'), which is not seen in this illustration, but without any unwanted leaks due to humidity or water from the cooling and defrosting phases, so that this space always remains dry. The compartmentalized cold thermal gel bag (26) has, as previously mentioned, horizontal and vertical adhesive strips (31) so that the small double-wall isothermal bag as a unitary whole must be flexible and therefore easy to use, especially when this cooling element is frozen. in addition, the compartmentalization contributes decisively both to the uniform distribution of the cooling capacity on the entire wall of the internal bag with the cold thermal gel bag (20) and to a better and uniform cooling of all the objects that are in the space main storage (19'). All of the above-mentioned layers of the inner bag with the cold thermal gel bag (20) are heat-glued together by the perimeter adhesive tape (32) to form a single, preferably rectangular, square, multi-layered sheet of material. or similar, which bends around the axis (21'). This forms the front wall (1Γ) and the back wall (12') of the inner bag with the cold thermal gel bag (20) which shows the side adhesive strips (30, 30') but does not appear in this illustration and at the free side of to them are attached the two hot-glued auxiliary opening strips (33, 33'), which are based on the elements (28, 28') of the closing/opening system, preferably double ziplock, and where the auxiliary opening strip (33') presents the notch (29) to facilitate the activation of the closing/opening system.

Figure 9 shows the vertical section A-A and the horizontal section B-B shown in Figure 1 of the small double-wall isothermal bag that better illustrates the geometrical characteristics of the two isothermal bags, the outer bag (10) and the inner bag with the cold thermal gel bag (20). which have two independent cooling systems, the detachable cold/warm thermal gel bags (16,16') and the compartmentalized cold thermal gel bag (26) for better cooling and maintaining the required pre-set temperature of small pharmacological items and other objects intended for storage and transport. The openings of the outer bag (10) and the inner bag with cold thermal gel bag (20) are each provided with separate easy-to-use pairs of closing/opening systems, not shown in the present illustration, for easy insertion / removing items in/out of the main storage space (19') of the internal bag with cold thermal gel bag (20) as well as inserting/removing the entire internal bag with cold thermal gel bag (20) and removable gel pouches thermal cold/hot (16.16') in/from the storage space (19) of the external bag (10).
