Definitions
- the present invention relates to the field of refrigeration devices, and more specifically relates to a portable refrigeration device for care products.
- Some care products for example cosmetics or pharmaceuticals, need to be applied cold to be effective.
- the SAMSUNG® company has thus proposed a refrigerator specifically dedicated to cosmetic products, of small dimensions and intended to be installed for example in a bathroom.
- a refrigerator specifically dedicated to cosmetic products, of small dimensions and intended to be installed for example in a bathroom.
- Such an apparatus is described in US-A-
- thermoelectric element coupled to a heat exchanger in a double bottom of the storage chamber.
- An electronic unit controls the thermoelectric element based on information provided by a temperature detector and according to parameters entered by the user.
- Ice-Source® a description of which can be found on the website www.ice-source.com.
- This product is contained in a self-cooling packaging to quickly and rapidly cool the cosmetic product just before its application.
- the packaging marketed to date is for single use and cools all of its contents once. It thus does not allow to cool small quantities of samples, nor to cool doses of different products.
- a self-cooling package for cosmetics contains a refrigeration tube connected to a cosmetic tank and opening through an outlet port of the product. This tube is surrounded by a cooling channel connected to a pressurized gas tank. Cooling is provided by expansion of gas along the channel surrounding the expulsion tube of the cosmetic product.
- This packaging makes it possible to instantly cool a small amount of product just before use, but the gases used - CFCs - are banned by European and American standards for ecological reasons. The use of other gases, such as CO 2 or butane, are no more acceptable for safety reasons, the CO 2 requiring a very high pressurization and butane being highly flammable.
- the package described in US-A-2005/0005628 does not allow to cool samples of different products.
- the invention proposes to use a portable device comprising a thermoelectric element and means for thermally contacting a dose of care product with the thermoelectric element.
- thermoelectric element of the device of the invention does not cool a volume, as is the case of the refrigerator described in document US-A-2003/0084670, but directly cools the product.
- the device of the invention therefore does not seek to keep cold a cosmetic product in its packaging, but allows to apply a quenching effect directly to a dose of product before use.
- the means for thermally contacting the dose of care product with the thermoelectric element comprise a product receiving plate on which the product is spread and which is adapted to be cooled by the thermoelectric element. ; or means for pressing a package containing the dose of product against the thermoelectric element.
- the invention also proposes a combination of a device according to the invention and a package containing a dose of care product to be cooled.
- a package containing a dose of care product to be cooled may comprise a product pouch or a tube intended to be pressed against a thermoelectric element of the device, for example by pressing means of the device.
- the device thus makes it possible to separately and successively cool doses of different products, each dose of product being able to be supplied in a package intended to be pressed against a thermoelectric element of the device.
- the invention also relates to a flexible package comprising two flexible heat-sealed sheets delimiting a pouch containing a dose of care product to be cooled by a device according to the invention and a neck extending in the extension of the pouch.
- Said flexible packaging further comprises at least one polarizer consisting of a hole through the heat-sealed flexible sheets and located on one side of the neck.
- the invention also relates to a package in the form of a metal tube containing a dose of care product to be cooled by a device according to the invention, the tube having a first end closed by a plug and a second end closed by a piston.
- the invention also relates to a method of cooling a dose of care product, comprising the steps of: placing the dose of product in thermal contact with a thermoelectric element of a cooling device according to the invention; - activate the thermoelectric element; collect the cooled product and apply it to an area to be treated. - AT -

- Figure 10 is a cross-sectional view of a portion of the refrigeration device according to a fourth embodiment of the invention
- FIG. 1 A first embodiment of the device according to the invention is described with reference to Figures 1 to 3.
- the device is illustrated with the general appearance of a box with a housing 10 and a lid 11 raised.
- the housing 10 has a limited size, of the order of 250 * 200 * 100 mm 3 .
- the upper wall of the housing 10 comprises a plate 2 for receiving a care product to be cooled.
- a marking 3 located substantially in the center of the plate 2 makes it possible to locate the most cooled zone of the plate 2 during operation of the device. A dose of product to be cooled will therefore be spread on the plate 2, at the marked area 3.
- Figure 1 also shows a control button 8, for example on the front wall of the housing. This control button 8 may be a simple on / off switch or a regulation button.
- the cover 11 When the device is not used, the cover 11 can be folded down to protect the product receiving plate 2, limit the size of the device and facilitate its transport. When the device is used, the lid 11 is raised to allow access to the plate 2 to spread the care product to be cooled.
- the inner face of the lid 11 may comprise a mirror, in particular when the product to be cooled is a cosmetic product.
- a display element 12 of the temperature of the marked area 3 of the product receiving plate 2 can be integrated into the device, for example in the cover 11 for good visibility.
- the temperature display element 12 may be of the bar graph type comprising a series of light-emitting diodes that turn on or off as the temperature of the plate 2 is lowered.
- An electrical connection connects the diodes to an electronic control circuit placed in the device and described later; this connection can pass through the hinges of the cover 11.
- Figure 2 shows the cooling device according to this first embodiment in lateral section with the lid 11 raised.
- Figure 2 thus shows the contents of the housing 10 of the device according to the first embodiment of the invention.
- a thermoelectric element 1 is placed under the plate 2, substantially at the level of the marking 3 identified in FIG. 1.
- the plate 2 thus constitutes a means of placing in thermal contact a dose of product to be cooled with the thermoelectric element 1.
- thermoelectric element 1 is connected to an electronic control circuit 8a and a power supply 7 which may be of the rechargeable battery type, such as for example a laptop battery.
- a power supply 7 of about 4OW under 9V to 4A is appropriate.
- the device according to the invention is portable because of limited dimensions and it also has a certain autonomy because it can be powered from the mains or its battery 7.
- the thermoelectric element 1 may be a Peltier cell having a cold face and a hot face when it is crossed by an electric current, the temperature difference being a function of the intensity of the current flowing through the cell.
- the cold side of the Peltier cell is in contact with the plate 2 intended to receive the product to be cooled and the hot face of the cell is placed on a heat evacuation assembly which may be a radiator 5 associated with a fan 6 or a thermal storage well, for example a water tank.
- Figure 3 will describe in more detail the cooling element 1 and the heat dissipating assembly 5, 6 according to one possible embodiment.
- FIG. 2 also shows the control button 8 intended to trigger the cooling of the plate 2.
- This button 8 can be a simple switch controlling an electronic circuit 8a which controls the intensity of the current flowing through the thermoelectric element 1 thanks to the indications of a temperature measurement sensor 9, of the thermistor type, for example.
- This electronic circuit 8a also makes it possible to control the temperature display element 12 described with reference to FIG. 1, thanks to the indications of the temperature sensor 9.
- the electronic circuit 8a can also include a delay which automatically stops the cooling at after a few minutes.
- Figure 2 also shows an intermediate plate 4 located between the cold face of the Peltier cell 1 and the plate 2 for receiving the product.
- the product receiving plate 2 is preferably made of stainless steel, for reasons of ease of cleaning and limiting the thermal leakage. Indeed, it is sought to cool strongly and quickly a given area of the plate 2 to ensure a quenching effect care product spread on the plate; we therefore want to avoid any heat loss over the entire surface of the plate. For this purpose, it is chosen to make the plate 2 stainless steel very thin, for example 0.5 mm. Stainless steel having a low thermal conductivity, the cold transmitted from the Peltier 1 cell to the plate 2 spreads little in the plate.
- an adapter plate 4 by example aluminum 6 mm thick, placed between the cold face of the Peltier 1 cell and the stainless steel plate 2 for receiving the product.
- This adapter plate 4 provides a certain thermal inertia and can integrate the temperature measurement sensor 9 connected to the electronic circuit 8a.
- the coldest zone of the plate 2, marked by the marking 3, corresponds to the zone above the adapter plate 4.
- the housing 10 may be plastic, wood or any other thermally insulating material.
- the housing 10 may have an upper wall for supporting the product receiving plate 2 which then constitutes only an outer casing wall of the housing. Indeed, when the plate 2 is stainless steel, as described above, it is very thin and little deform when a user spreads or collects the product. The upper wall of the housing will then be partially pierced to a dimension slightly greater than that of the adapter plate 4, to allow direct thermal contact with the product receiving plate 2.
- Figure 3 illustrates an embodiment of the invention. heat removal assembly with the thermoelectric element 1 and the adapter plate 4. The assembly illustrated in FIG. 3 is intended to be placed in the housing of the device illustrated in FIGS. 1 and 2.
- the Peltier cell 1 is placed between the adapter plate 4 and a radiator 5.
- the cold face of the Peltier cell 1 is in contact with the adapter plate 4, but could also be free and contact directly the product receiving plate 2 when assembled in the device housing.
- the hot face of the Peltier cell 1 is in contact with the radiator 5.
- the radiator 5 is made of a thermally conductive material, for example aluminum or copper.
- the radiator 5 has a plate forming a contact surface with the hot face of the Peltier cell 1 and fins connected to this contact surface to evacuate the heat transmitted by the Peltier cell.
- a fan 6 may further ventilate said fins to improve the dissipation capacity of the radiator 5.
- the fan 6 can be started as soon as the device is put into operation, for example to be controlled by the on / off button 8 of the device described with reference to Figures 1 and 2.
- the fan 6 may also be controlled by the electronic circuit 8a. It can be started only beyond a certain threshold of temperature to limit noise, for example by the electronic circuit 8a receiving a measurement of a temperature sensor of the hot face of the Peltier cell 1.
- the fan 6 is selected low power, of the order of lWatt; this power is sufficient to evacuate the heat produced by the Peltier cell (a few Watt of average thermal power) while limiting the noise generated.
- the device according to the first embodiment of the invention can be used for the application of a care product as follows.
- a care product for example a cosmetic cream, needs to be applied cold after quenching effect on an area to be treated.
- a dose of this product is spread on the receiving plate 2 of the device, preferably uniformly and in a thin layer at the marking 3.
- the control button 8 is then activated to start the device; an electric current passes through the thermoelectric element 1 and causes rapid and significant cooling of the zone 3 of the plate 2 and thus the spread care product.
- the device can also be switched on before spreading the product on the receiving plate 2 of the device, the product then being spread over an already cold surface. In this case, activation of the Peltier 1 cell is maintained for a few minutes to ensure the quenching effect of the spread product * .
- the device according to the invention makes it possible to cool the plate 2 for receiving the product at a temperature below 8 ° C. in less than 5 minutes. More specifically, the marked area 3 corresponding to the location of the Peltier cell 1 under the plate 2 can be cooled to a temperature below 5 ° C in less than 2 minutes. When the spread care product has thus been rapidly cooled, the user can collect it and apply it on the area to be treated, for example a portion of skin - face, hands, bust or other.
- FIGS. 4 to 6 A second embodiment of the device according to the invention is described with reference to FIGS. 4 to 6.
- the elements identical to those described with reference to FIGS. 1 to 3 bear the same reference numbers.
- Figure 4 shows a perspective view of the device according to the second embodiment with the lid 11 raised.
- the lid 11 may comprise a mirror and a temperature display element 12 as previously described.
- the housing 10 has a plate 2 'forming its outer upper wall; this plate 2 'has a recess intended to receive a pressing element 20.
- the product to be cooled is no longer spread on the plate 2' but is placed in a single-dose flexible package 21 which is pressed against the thermoelectric element by a pressing element 20.
- the package 21 will be described in detail with reference to Figure 9; and the pressing member will be described in greater detail with reference to FIGS. 5 and 6.
- the cover 11 may be folded over the plate 2 'and the pressing member 20 to limit the size of the device and facilitate its transport.
- the plate 2 ' may be made of the same material as the housing 10, wood or plastic, be stainless steel as described above.
- the pressing element 20 may be located above the plate 2 'which then has no recess.
- the housing 10 does not have a lid or has a lid with a recess receiving the pressing element 20 protruding from the plate 2 '.
- FIG. 4 shows positioning studs 41 of the flexible packaging 21. These studs 41 are intended to cooperate with polarizers provided in the packaging as will be described with reference to FIG. 9.
- pressing element 20 is in the retracted position; the pads 41 are disengaged and the pressing element 20 can pivot on its rear axis.
- Figure 5 shows the housing 10 of the device according to this second embodiment in lateral section with the lid 11 raised.
- FIG. 5 thus shows the thermoelectric element 1 placed between an adapter plate 4 and a heat evacuation assembly 5, 6.
- the heat evacuation assembly can be that described with reference to FIG.
- the thermoelectric element 1 is also connected to an electronic control circuit 8a and to a power supply 7.
- FIG. 5 also shows the pressing member 20 having a hinged movable plate.
- the pressing element 20 is raised to place the flexible packaging unit of the product 21 to be cooled in the device, then folded to press the package against the adapter plate 4.
- the pressing means 20 of the flexible package 21 and constitute means for contacting a thermal dose of product to be cooled with the thermoelectric element 1.
- FIG. 6 illustrates a detail referenced A in FIG. 5.
- the pressing element 20 is mounted on an axis 25 in order to pivot to give access to a zone cooled by the thermoelectric element. 1.
- the package 21 is placed on the plate 2 'of the housing 10 facing the adapter plate 4 which provides a certain thermal inertia and can integrate a temperature measurement sensor 9 connected to the electronic circuit 8a.
- the package 21 could also be directly pressed against the cold face of the thermoelectric element 1.
- FIG. 6 also shows a switch 8 'intended to trigger the cooling of the product contained in the packaging 21.
- This switch 8' can be actuated by the pressing element 20 when it is folded down to press the flexible packaging 21 against the adapter plate 4.
- the switch 8 ' can control the electronic circuit 8a.
- the positioning studs 41 of the flexible packaging 21 may serve as a switch for triggering the cooling of the product when the pressing element 20 is folded down to press the flexible packaging 21.
- the pressing member 20 comprises a movable plate 22 pressing consisting at least in part of a dense material to ensure the pressing effect by its own weight. This movable plate 22 is articulated on the axis 25 in an L-shaped housing.
- the movable plate 22 can thus have a retracted pivot position on the axis (FIG. 4) or an advanced horizontal pressure position (FIGS. 6).
- An insulating layer 23 may be provided on the inner face of the pressing element to limit the thermal leakage of the refrigerated product to the pressing plate 22.
- the insulating layer 23 is therefore located under the hinged movable plate 22 to be positioned between said plate 22 and the flexible package 21 pressed.
- the positioning studs 41 of the packaging 21 are no longer visible because the mobile plate 22 of the pressing element 20 has bores accommodating said pads when the movable plate is folded in the advanced position to ensure uniform pressure on the flexible packaging 21 by its own weight.
- thermoelectric element 20 could be integrated on the inner face of the pressing element 20.
- the flexible packaging 21 would then be sandwiched between two thermoelectric elements.
- the pressing element 20 would then comprise the movable plate 22, the insulating layer 23 and the second thermoelectric element.
- FIG. 6 also shows a temperature sensor 13 placed on the insulating layer 23 of the pressing element, the measuring surface of the sensor 13 being in contact with the packaging 21 of the product to be refrigerated.
- a thin conductive plate 24 can be added to the insulating layer 23. This plate 24, 0.5 mm aluminum for example, allows to integrate the temperature of the product over a wider area than the surface of the sensor without adding excessive heat capacity.
- the temperature sensor 13 is then placed between the insulating layer 23 and the conductive plate 24.
- the conductive plate 24 can be thickened to about 3 or
- thermoelectric element 4 mm and serves as adapter plate between the second thermoelectric element and the flexible packaging to be cooled.
- the temperature sensor 13 is then placed on the conductive plate 24 of adaptation.
- the temperature measurement of the sensor 13 may be indicated on the display element 12 of the lid 11. This measurement will make sure that the product in the package 21 is refrigerated well before its application.
- the temperature measurement of the sensor 9 can be used by the electronic control circuit
- thermoelectric element 8a to regulate the operation of the thermoelectric element to prevent the product from being frozen in the package 21.
- FIG. 9 illustrates a single-dose flexible package 21 for use with the device of Figures 4 to 6.
- the single-dose package 21 consists of two substantially rectangular flexible sheets heat-sealed at the periphery to delimit a pouch 26 with a neck 27.
- the pouch 26 of the package 21 is filled with a dose of care product that needs to be activated. by a quenching effect, for example a cosmetic product or a dermatological treatment product.
- the volume of the pouch 26 can be between 2ml and 8ml for example.
- the neck 27 extends in the extension of the pocket, in the length of the package 21; it is relatively long to exceed the means of pressing the device as will be described later. Indeed, it will seek to tear or cut the neck 27 to expel the product out of the pouch 26 while the pouch is still held in the pressing means of the cooling device according to the invention. It is therefore necessary that the neck 27 is accessible without the edges of the housing 10 hindering its opening.
- the package 21 has at least one polarizer 40.
- the package 21 has two polarizers 40 consisting of two holes drilled in the heat-sealed sheets on either side of the neck 27. These keying holes 40 are intended to be plugged onto the pads 41 provided on the housing 10 of the cooling device.
