Description

[0001] The present invention relates to a cosmetic bag with a cooling function for the transport and storage of cosmetics, medicines and other heat-sensitive substances and serums.

[0002] In many cases, it is necessary to store certain care products, medicines and cosmetics in a cool, specific temperature range in order to ensure their long-term quality and usability.

[0003] This is especially true when traveling, for example to warmer destinations and accommodations without special cooling facilities.

[0004] For example, insulin needed by diabetics should be stored at refrigerator temperatures for extended periods, if possible, and not above 30°C for short periods to maintain its effectiveness. Similar requirements apply to vitamin C serums and eye care products.

[0005] Portable cooling containers carried by people, such as cosmetic boxes or cool bags, are intended to remedy this situation and ensure the necessary cooling of perishable products, at least for a short time.

[0006] Such cooling containers should be easy for people to transport and store, and should provide sufficient and long-lasting cooling for indoor use.

[0007] It should also be possible to transport different products according to their optimal storage temperature.

[0008] Some suggestions for cosmetic bags or cooling bags have been made in this direction, describing solutions to these cooling problems.

[0009] Proposals for containers with a cooling function that can be carried on board are known, particularly from the patent literature.

[0010] For example, the German utility model DE 29500497 U1 describes a small case, in particular a cosmetic bag, which has a lower part 11 and a lid part 12 hinged thereto.

[0011] The lower part 11 of the small case is designed to accommodate heat-sensitive products in one or more receiving spaces, while the lid part 12 houses a predominantly electrically operated cooling unit 33.

[0012] According to the invention, the cover part 12 there is held interchangeably with the cooling unit 33.

[0013] The cooling unit 33 should preferably be designed as a rechargeable battery and be accommodated in the same receiving space as the cooling unit 33.

[0014] The battery can be electrically connected for charging via a connection socket 36 or the cooling unit 33 can also be operated directly in a stationary manner via an external connection.

[0015] However, there is no provision for temperature control or display, nor is there sufficient thermal insulation of the container walls, which in certain situations can be expected to reduce the reliability of the cooling.

[0016] Therefore, it is an object of the present invention to propose a cosmetic bag or a similar cooling container which allows the solution of the aforementioned problems for the storage and transport of temperature-sensitive products from the health and cosmetics sector.

[0017] This problem is solved by the characterising features of the first claim in conjunction with the generic term.

[0018] Further advantageous embodiments of the invention are specified in the subclaims.

[0019] The cosmetic bag with cooling function according to the invention or a similar container is particularly suitable for the transport or short-term storage of heat-sensitive medicines or cosmetics, such as creams or oils, medications and serums, and has several different temperature zones inside, which are located in the lower and upper part of the cosmetic bag.

[0020] The temperature zones are preferably separated from each other by thermally insulating walls for different product groups and arranged one above the other.

[0021] To ensure reliable cooling of the temperature ranges and during use of the cosmetic bag, various cooling elements are provided.

[0022] The main cooling element is a Peltier cooling system, which is powered by a rechargeable battery It is powered by a USB cable and is housed in the lower part of the cosmetic bag. The battery can be charged externally via a USB port.

[0023] The entire Peltier cooling system features temperature sensors and an automatic control system to maintain the set temperature in each cooling compartment.

[0024] Thermally insulated walls, such as vacuum insulation through vacuum panels, ensure long-lasting temperature stability in the individual cooling compartments.

[0025] Additionally, cold-storing gel pads are provided as cooling agents, allowing for further or additional cold penetration into the cooling compartments. A digital temperature display and touchscreen temperature control are located in the top of the cosmetic bag to monitor and adjust the internal temperatures.

[0026] According to the invention, the top and bottom parts of the cosmetic bag are connected by a liquid-tight zipper, which also contributes to the temperature insulation of the cosmetic bag.

[0027] The individual temperature ranges in the cosmetic bag 1 according to the invention extend from approximately 3°C to 11°C, depending on the setting of the automatic cooling function.

[0028] The invention will now be explained by means of embodiments and a Fig. 1 will be explained in more detail.

[0029] The Fig. The opened cosmetic bag 1 shown in Figure 1 initially consists of an upper part 5, which is hinged to the lower part 15 by means of conventional hinges or connections.

[0030] The lower section 15 contains a large cooling compartment 11 and a Peltier cooling system 10 with a rechargeable battery built into the rear panel. The battery is connected externally for charging via a USB port (not shown).

[0031] The large cooling compartment 11 is also designed for intensive cooling due to the direct arrangement of the Peltier cooling system 10 and, depending on the setting, has the lowest temperature range of the cosmetic bag 1.

[0032] The Peltier cooling system 10 is a very effective and quiet thermoelectric cooler and operates without moving parts.

[0033] Peltier cooling systems are well known and are available in various versions on the market.

[0034] For better insulation of the cooling compartment 11, the four side wall surfaces are preferably designed as thermally insulated walls 2.

[0035] Likewise the base plate.

[0036] According to the invention, the insulated walls 2 can also be designed as vacuum-insulated walls or double walls 2 with additional insulating materials.

[0037] In a further embodiment, the thermally insulated walls 2 are formed with a layer of vacuum-insulated panels 2, which effectively protects against penetrating heat. Such layers are currently also used in high-performance cooler bags and thermos flasks.

[0038] Other options for thermal insulation include a heat-reflecting interior coating of the walls 2 or the use of good insulation materials, which are also used in thermos flasks or cool boxes.

[0039] A heat-reflecting layer can be formed, for example, by an aluminum foil.

[0040] By means of a thermal protection layer 13 (dotted lines in Fig. 1) the cooling compartment 11 is thermally insulated from the cooling compartments 8 above it.

[0041] The temperatures in the individual cooling compartments 8 above are usually higher than in the cooling compartment 11 with intensive cooling and form a cooling area with medium cooling.

[0042] According to the invention, the cooling compartments 8 are closed at the top by a transparent lid 9 and divided by thermally insulated partition walls.

[0043] The lid 9 allows the user to quickly view and check the contents of the cooling compartments.

[0044] The number and dimensions of the 8 cooling compartments are flexible and can be adapted to requirements. The 8 cooling compartments are primarily designed to store creams and oils at a mild temperature (medium temperature range).

[0045] According to the invention, one or more of the cooling compartments 8 are designed as a liquid-tight, sealed cooling compartment 12. Liquid products can be stored and transported here in a leak-proof manner.

[0046] An antibacterial inner coating can also be provided in the cooling compartments 8 and 11 to protect against contamination.

[0047] A further advantageous embodiment of the invention provides for the insertion and storage of additional cold gel pads 3. These gel pads 3 can provide additional cooling both in the cooling compartments 8 and, preferably, in the larger cooling compartment 11. Especially when opening the cosmetic bag 1, the gel pads 3 ensure temperature stability due to the cold they store.

[0048] According to the invention, the cosmetic bag 1 has in its upper part 5 ( Fig. 1) via an integrated high-resolution touch-screen display for monitoring and adjusting the temperature in the refrigerator compartment 11 and in all refrigerator compartments 8.

[0049] For this purpose, corresponding temperature sensors (not shown) are provided, which are connected to the automatic temperature control and display of the touch screen 4 and control the Peltier cooling system 10 according to the measured temperature values.

[0050] In a further advantageous embodiment of the invention, the mutually facing edges of the upper part 5 and lower part 15 are provided with a waterproof zipper 6 for closing the cosmetic bag 1.

[0051] The waterproof zipper 6 has laminated teeth, which ensures optimal protection against moisture penetration and air exchange with the environment.

[0052] Such zippers with laminated teeth provide excellent sealing against external penetration of water and air.

[0053] In the cosmetic bag 1 according to the invention, the sealing plays a crucial role in preserving cold and freshness inside and minimizing the exchange with the outside temperature.

[0054] The proposed laminated teeth made of robust material, such as plastic or aluminum, also with integrated seal, improves the temperature stability and the stability of the entire cosmetic bag 1.

[0055] Waterproof zippers as closure mechanisms are specifically designed to ensure a permanent seal of the interior, which is particularly important in this cooling application.

[0056] In a further advantageous embodiment of the invention, solar cells of a photovoltaic power supply are attached to the outer sides or on the upper part 5 of the cosmetic bag 1, which can additionally charge the battery.

[0057] In a further advantageous embodiment of the invention, a fabric compartment 7 with an upper rubber band for securing the closure is arranged in the interior of the upper part 5.

[0058] Just like in the fastening band 14 above for small parts ( Fig. 1), preferably with individual loops, packaged cosmetics or medicines can be stored here without special cooling.

[0059] This third temperature zone in the upper part 5 is located above the two lower temperature zones in the cooling compartments 8 and 11 with low temperatures and should only be cooled slightly.

[0060] In an advantageous embodiment, the cosmetic bag 1 according to the invention should have the following dimensions and properties. - Height of 15 cm, which is ideal for bottles with pipettes. - Width: 25 cm, with enough space for several products next to each other. - Depth: 18 cm, compact and easy to transport.

[0061] Form: - Rectangular shape with rounded corners for a modern and elegant appearance. - Stable base for secure standing, even on uneven surfaces.

[0062] The proposed cosmetic bag 1 has the particular advantage over other known cooling bags of this type that it has several different but self-contained temperature zones in which products can be stored and safely transported at different temperatures.

[0063] This allows for a versatile use of the cosmetic bag 1, which ensures the quality and usability of the stored products.

[0064] The Cooling Cosmetic Bag 1 is an elegant, compact solution for keeping cosmetic products fresh while traveling or in everyday life. It combines modern design, high-quality materials, and reliable cooling technology to safely store delicate products such as serums, creams, medications, or oils at a constant temperature, preferably between 4 and 10°C.
