Description

Technical Field

[0001] The present invention relates to the field of steaming devices using a base comprising a separate liquid container, and more precisely to a system for closing such a container. Background Art

[0002] Numerous portable steam-generating devices are known in the prior art, connected to a base comprising a liquid container, typically water. This configuration, in which the device comprises a portable unit and a base for securing during use, improves the practicality of the steam device while allowing the portable unit to be lighter and smaller in size, with the liquid stored in the base comprising the container. This also allows for the storage of larger amounts of liquid and increases the device's evaporation capacity.

[0003] The portable steam device may be any type of household appliance comprising a base with a liquid container, such as an ironing type device or a mist sprayer for the face.

[0004] Another type of portable steam device is a steam-based hairdressing device, such as that described in EP2449912. In this device, a base comprises a fluid container, and a portable unit, separate from the base and connected to the container via a cable, comprises a vaporizing mechanism for vaporizing the fluid contained in the container and a dispensing mechanism for dispensing the generated steam onto the hair. The base includes a lid having a fixed portion and a pivoting portion for filling the container with the fluid. The lid may be completely removable to allow replacement of a demineralization mechanism, such as a cartridge. However, there is no mechanism to prevent the lid from opening, and during use, particularly when the container is full, when transporting the container, or when the base is suddenly moved, the container may overflow or liquid may splash.

[0005] Another device within the scope of hairdressing equipment is described in document FR3052029. Here, the base comprises a support and a removable container, which is configured to occupy a detached position, in which the container is separated from the support, and an operating position, in which the container is fluidly engaged with the support. The removability of the container facilitates filling the container with liquid. Furthermore, the container includes a closure element, comprising a lid, which pivots relative to a liquid filling opening between a fluid filling position, in which the lid provides access to the filling opening, and a closed position, in which the lid seals the filling opening. However, the lack of any element to lock the closed position allows for splashing of liquid onto the exterior of the container when the base or filled container is being handled. Furthermore, during use, and particularly if the container is very full and the user pulls hard on the cable during use, spillage of water may occur if the base is not positioned on a level working surface. This spillage may be caused, in particular, by movement of the base relative to the support.

[0006] Therefore, there is a risk that the fluid contained in the container may overflow, which may cause various inconveniences for the user and may even lead to the risk of malfunction of the device. Summary of the Invention

[0007] The object of the present invention is to overcome the aforementioned problems and in particular to improve the sealing of the closing area of the water container in order to limit the splashing of water when transporting the household appliance with the water container mounted thereon, separated from its base.

[0008] These objects are achieved by a fluid container for being detachably mounted on a base of an apparatus for generating steam, the container comprising an opening for filling the container with a fluid and a lid mounted at the opening in a pivotable manner between a closed position in which the opening is closed and an open position allowing the filling of the container, characterized in that the fluid container further comprises a peripheral rib and a groove, the peripheral rib protruding towards the outside of the container and formed over the entire periphery of the opening, the groove being formed by a hollowed-out portion between the peripheral rib and the outer wall of the container, and the lid comprising an inner wall in which a peripheral groove is formed, the peripheral groove being intended to rest on the peripheral rib at the opening when the lid is in the closed position, the lid further comprising at least one guide mechanism protruding relative to the inner wall of the lid, the guide mechanism being arranged at least partially along the peripheral groove so as to abut against the peripheral rib in the closed position.

[0009] The fluid container may include the following features, taken alone or in combination:

[0010] The guide mechanism is formed to engage the side wall of the peripheral rib by friction to maintain the lid in the closed position;

[0011] The guide mechanism includes a tab configured to contact a sidewall of the peripheral rib;

[0012] The guide mechanism includes at least one lug configured to contact a corresponding cavity in a side wall of the peripheral rib;

[0013] the lid having a shape extending between a rear region and a front region, the rear region including a connecting element for mounting the lid on the container along a pivot connection, and the front region including a locking element for cooperating with a complementary locking portion of the peripheral rib to retain the lid in a closed position;

[0014] The locking element is configured to cooperate with the complementary locking portion by snapping or friction;

[0015] The cover further includes two side guide flaps extending between the front region and the rear region;

[0016] The container further includes an additional rib arranged at the opening so as to protrude from at least a portion of the peripheral rib toward the lid, the peripheral rib having a constant height, and the additional rib having a variable height along the arc shape;

[0017] The additional rib is arranged at the rear region;

[0018] The peripheral rib includes two straight portions connected by two curved portions;

[0019] The two straight portions of the peripheral rib are arranged at the front region and the rear region respectively;

[0020] the two curved portions of the peripheral rib are not provided with elements forming an obstacle between the peripheral rib and the peripheral groove of the lid in the closed position;

[0021] In the closed position, the cover is configured to cooperate with the opening to maintain ventilation.

[0022] According to another aspect, there is provided a hair cutting device comprising a base equipped with a detachable container such as described above, a portable unit detachable from the base, and a cable fluidly connecting the base and the portable unit.

[0023] The hair cutting device may include the following features, taken alone or in combination:

[0024] The portable unit includes two arms movable relative to each other between an approach configuration for treating hair and a separated configuration for inserting hair to be treated;

[0025] The two movable arms are connected by a hinge so as to be pivotable between the close configuration and the separated configuration like a clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 2 A perspective view showing a fluid container according to an embodiment of the present invention;

[0029] Figure 3 Shown for closing according to Figure 2 A perspective view of the inner wall of a lid of a fluid container according to an embodiment.

[0030] Only elements necessary for understanding the present invention are shown. To facilitate reading of the drawings, similar elements are given the same reference numerals throughout the drawings. DETAILED DESCRIPTION

[0031] Figure 1 1 is a perspective view of a base 1 of a household appliance for generating steam, the base 1 being connected to a portable unit (not shown) separate from the base 1 via a cable 7, the cable 7 fluidically connecting the base 1 and the portable unit, and even electrically connecting the base 1 and the portable unit. The base 1 can also be connected to a power supply such as a power socket via an electrical cable 8.

[0032] The base comprises a support portion 2 and a fluid container 3, preferably arranged to be removably mounted on the support portion 2. The support portion 2 comprises a substantially flat abutment wall that allows the base 1 to be placed on a work surface, so that the base 1 rests on the work surface. Preferably, the abutment wall comprises a plurality of fixing suction cups that allow the support portion to be removably fixed to the work surface. These suction cups are thus used to contact the work surface to ensure that the base 1 is fixed to the work surface.

[0033] Figure 2 A perspective view of the base is shown at the location of the container 3. The container 3 is arranged to occupy a working position in which it cooperates fluidically with the support 2. If the container 3 is removable, it can be separated from the support 2 to occupy a detached position in which it is separated from the support 2, thus facilitating filling and transport of the container 3.

[0034] The container 3 comprises an opening allowing filling of said container 3 with a fluid.

[0035] The fluid is any type of fluid suitable for use with a steam-generating household appliance. Typically, it can be a liquid, such as water or water to which a maintenance agent for maintaining the household appliance has been added, such as a product to prevent scale formation. In a usage mode in which the portable unit is a device for styling hair, typically a hair straightener, the fluid can be liquid water or a mixture of water and a hair care product.

[0036] like Figure 1 As shown, the opening 4 is typically arranged on the upper portion of the container 3 , near the end of the base 1 , opposite the end of the base 1 having the cable 7 and the power supply 8 .

[0037] Figure 3 A cover 5 is shown for pivotal mounting at the opening 4. The cover 5 can be pivoted between a closed position, in which the opening 4 is closed, and an open position, which allows the container 3 to be filled.

[0038] In order to realize a pivot connection, referred to as a hinge, between the lid 5 and the container 3 , the lid 5 comprises, for example, two female hinge members 6 , 6 ′ intended to cooperate with two male hinge members 13 , 13 ′ formed on the container 3 .

[0039] In the working position, container 3 is configured for fluidic engagement with support 2. Specifically, container 3 is in fluidic communication with support 2 of base 1 via an outlet opening. The outlet opening may include a sealing element around its perimeter. Thus, when container 3 is in the working position, the fluidic connection with support 2 is sealed. The sealing element may comprise, for example, a gasket or a flexible wall made of silicone.

[0040] A pump, such as a peristaltic pump, may be provided in the support portion and configured to clamp the flexible tube housed in the cable 7 so as to pump or pressurize the liquid between the fluid container 3 and the portable unit. Therefore, in order for the pump to function properly, preferably, the container 3 does not form an airtight seal when the lid 5 is in the closed position.

[0041] When the container 3 is filled with a liquid, such as water, and when the base 1 is subject to sudden movement, several structural elements are provided on the lid 5 and the container 3 to maintain the lid 5 in a closed position and to limit splashing of liquid when the container 3 or the base 1 is being transported. The container, in particular, includes a peripheral rib 9 at the opening that projects toward the exterior of the container 3 and is formed along the entire periphery of the opening 4. A peripheral groove 10 is formed in the inner wall of the lid 5 and is intended to rest on the peripheral rib 9 when the lid 5 is in the closed position. Preferably, the groove 10 is also formed along the entire periphery of the opening 4, thereby limiting the risk of spillage, particularly at the front. Thus, the peripheral rib 9, which forms a raised portion, combined with the peripheral groove 10, which forms a recessed portion, collectively forms a barrier that prevents the passage of liquid contained in the container, thereby improving the container's sealing properties.

[0042] The lid 5 also includes at least one guide mechanism 11 projecting relative to the inner wall of the lid. The guide mechanism 11 is arranged at least partially along the peripheral groove 10 so that when the lid 5 is in the closed position, it abuts against the peripheral rib 9 and maintains the closed position when the base 1 is carried, primarily when the container 3 is filled with liquid. Specifically, the guide mechanism 11 can abut against the inner sidewall of the peripheral rib. The guide mechanism 11 can thus prevent the container lid from accidentally opening by friction. Furthermore, the guide mechanism 11 allows the lid 5 to be guided relative to the container 3 when closing it, thereby ensuring good positioning of the lid 5 relative to the opening 4 and an optimal seal.

[0043] Carrying refers to the user moving the container 3. Typically, when using a household appliance, the fluid is gradually consumed. In an embodiment, when the container 3 is empty, the user can remove the container 3 from the support 2 in order to fill the container with fluid. The container 3 is thus in a detached position. After filling the container 3, the user needs to move the container 3 before positioning the container 3 on the support 2 of the base 1 and in the working position. During the movement, the liquid in the container 3 may slosh, and if the container 3 is full, the liquid may overflow or splash to the outside. The arrangement of the guide mechanism 11 and the groove 10 of the lid 5 in the rib 9 of the container 3 allows these problems to be avoided.

[0044] According to a possible and preferred embodiment, the peripheral groove 10 of the cover 5 has substantially the same dimensions over the entire periphery of the opening. Preferably, the groove 10 extends over a width between 1 and 2 mm, typically 1.8 mm, and has a depth of approximately 1 mm.

[0045] The container 3 further comprises a groove 12 formed by a hollowing out between the peripheral rib 9 and the wall of the container 3, preferably the outer wall of the container 3. The groove 12 can be of a size that allows the liquid to be recovered in the event of a possible overflow of the container 3, so as to avoid splashing or splattering of the liquid. The rib 9 and the groove 12 as a whole define a barrier in front of the edge of the container 3. The hollowing out is preferably configured to form a storage area in order to collect liquid that may overflow from the container 3 and prevent the liquid from flowing onto the work surface.

[0046] A portion of the groove 12 may extend, in particular, at the hinge female members 13, 13' for respectively assembling with the hinge female members 6, 6' of the lid 5 to form a pivot connection, a portion of the groove 12 may extend, in particular, on the rear region to receive liquid when liquid splashes when the lid 5 is in the open position, and a portion of the groove 12 may extend, in particular, at the front region, to allow slight overflow when the base falls over without liquid splashing to the outside of the container 3.

[0047] In an embodiment, the lid's guiding mechanism 11 is configured to cooperate with the sidewalls of the peripheral rib 9 by friction and, advantageously, by elastic deformation, to maintain the lid 5 in the closed position. Typically, the lid's guiding mechanism 11 defines a shape similar to that defined by the sidewalls of the container's rib 9, but has slightly larger dimensions, such that a slight deformation of the lid's guiding mechanism 11 is necessary to achieve the closed position. The guiding mechanism 11 is thus arranged to exert pressure on a portion of the inner sidewall of the peripheral rib 9, thereby maintaining the lid 5 in the closed position on the container 3 by friction, even when a moment is exerted by the liquid contained in the container 3 and tends to open the container. This can thereby prevent splashing of liquid when, for example, the base 1 is being handled.

[0048] The guide means 11 comprise, for example, a tab, i.e. a substantially flat and elongated projection, the wall of which is configured to come into contact with a portion of the side wall of the peripheral rib 9 while preferably deforming elastically when the lid 5 is closed so as to exert pressure on a portion of the side wall of the rib 9, thereby allowing the closed position to be maintained by friction.

[0049] Alternatively or additionally, the guide means 11 comprises pins or lugs protruding towards the side walls of the ribs 9 in order to increase the friction between the lid 5 and the container 3 in order to maintain the closed position of the lid 5. Typically, corresponding cavities are formed in the side walls of the peripheral ribs 9 so that the pins or lugs can be configured to come into contact with corresponding cavities in the side walls of the peripheral ribs 9.

[0050] exist Figure 1 In the embodiment of the present invention, the base 1 has a generally longitudinal shape along the longitudinal and oval directions, and may be generally circular. In the working position, the upper portion of the support 2 and the container 3 are configured to be assembled with each other so that their outer surfaces form a smooth, continuous outer surface of the base 1. A generally longitudinal shape refers to a generally elongated shape, i.e., one dimension being larger than the other. Such a generally longitudinal shape may be, for example, a generally rectangular shape, a generally triangular shape, or a generally rectangular shape. Figure 1 The roughly oval shape shown.

[0051] In an embodiment, the cover 5 has a generally longitudinal shape along the longitudinal direction of the base 1 or alternatively along a direction perpendicular to the longitudinal direction of the base 1. Such a generally longitudinal shape may be, for example, Figure 3 The roughly triangular shape shown.

[0052] The cover 5 extends between a first region, the rear region, and a second region, the front region, of the container 3. The front region is an area arranged near a first end of the base 1, which is opposite to the second end of the base 1, and defines the rear region. Figure 1 In the example of FIG, the rear area refers to an area arranged in the central portion of the base 1 and closer to the end portion of the base 1 including the cable 7.

[0053] Preferably, the rear area comprises a connection element allowing the lid 5 to be mounted on the container 3 along a pivot connection. The connection element is typically two rods or cylinders fixed to the container 3 in the vicinity of the opening 4, forming male hinge members 13, 13' intended to be inserted into two substantially cylindrical hollow parts of the lid 5 forming female hinge members 6, 6', respectively.

[0054] Preferably, the cover comprises, at the front area, a locking element 14 intended to cooperate with a complementary locking portion 15 of the peripheral rib 9 in order to keep the cover 5 in the locked position.

[0055] For example, the locking element 14 cooperates by snapping or friction with the complementary locking portion 15. Typically, elastic deformation of the locking element 14 of the lid 5 is therefore necessary in order to move from the open position to the closed and locked position.

[0056] In another example, locking element 14 may comprise a cylindrical hollow portion with at least one pin formed therein, projecting toward the interior of the cylinder. The complementary locking portion 15 of peripheral rib 9 thus has a generally cylindrical outer surface slightly smaller than the cylinder defined by the inner surface of the lid's locking element 14. The complementary locking portion 15 of peripheral rib 9 includes a blind cavity configured to receive the pin protruding from the cylindrical hollow portion of lid 5. When lid 5 is closed, the user can apply pressure to the lid, causing the pin protruding from the lid to elastically deform and insert into the corresponding blind cavity of peripheral rib 9. Thus, when insufficient force is applied to lid 5 to force it open, the closed position is maintained. Typically, the elasticity of the material, the size, and the number of the pins are calibrated so that the force required to open the lid is greater than the force that could be exerted on the inner surface of lid 5 by liquid splashing, thereby preventing unintended opening of the lid 5. The pins also limit potential lateral travel.

[0057] In another embodiment, the locking element 14 is configured to be in contact with a complementary locking portion 15 so as to exert friction that prevents the flap from opening.

[0058] This locking system allows the lid 5 to remain in the closed position even in the event that the container should tip over. Spillage of the liquid contained in the container 3 is thus limited.

[0059] Preferably, the container 3 comprises a hollowed-out portion 16 at the front region configured to facilitate opening of the lid 5 by a user.

[0060] Preferably, and Figure 3 In the embodiment shown, the cover 5 comprises two side guide fins 17, 17' formed to extend between a first front region and a second rear region. Each guide fin 17, 17' is formed, for example, as a generally elongated protrusion along one side of the cover 5, the side wall of the guide fin being configured to contact a portion opposite to the side wall of the rib 9.

[0061] Preferably, each guide tab 17 , 17 ′ is elastically deformed when the lid 5 is closed so as to exert pressure on a portion of the side wall of the rib 9 , allowing the closed position to be maintained by friction.

[0062] Typically, the fins 17, 17' are slightly inclined toward the outside. The fins 17, 17' are arranged approximately symmetrically along the longitudinal direction relative to the axis of symmetry of the base 1. Each fin 17, 17' preferably extends over a length of between 10 mm and 30 mm, typically 18 mm, between the front and rear regions. The fins 17, 17' preferably have a width of approximately 1 mm.

[0063] The width of the flaps 17, 17' should not be too large so as to be elastically deformable and not too resistant to friction when the lid 5 is closed. The flaps 17, 17' project relative to the inner wall of the lid 5 by a height between 1 and 3 mm, typically 1.8 mm, preferably greater than the depth of the peripheral groove 10.

[0064] The two flaps 17, 17' also serve to form a barrier for the liquid in the event of spillage. The flaps 17, 17' can also improve the stability of the lid 5 in the closed position, especially if the locking system is worn. Finally, the flaps 17, 17' contribute to good guidance of the lid 5 when closing, while ensuring good positioning of the lid 5 relative to the opening 4, even in the event of significant wear on the hinges.

[0065] The container 3 and the lid 5 can be made of two separate parts by molding, for example by thermoplastic injection, so that the groove 10 and the rib 9 are part of the structure of the lid 5 and the container 3, respectively. Typically, the container 3 and the lid 5 can be made of a polymer material suitable for the use, such as ABS. This allows the container 3 and the lid 5 to be formed into a single unit that has good resistance to impacts and is light and relatively rigid.

[0066] According to an embodiment, the container 3 further comprises an additional rib arranged at the opening 4 so as to protrude from at least a portion of the peripheral rib 9 toward the lid 5. Typically, the additional rib is arranged at the opening 4 and protrudes from the inner wall of the container 3 toward the lid 5. The additional rib may be in the vicinity of the peripheral rib 9, typically extending along a portion of the peripheral rib 9.

[0067] According to an embodiment, the peripheral ribs 9 have a constant height, while the possible additional ribs have a variable height along the arc. Preferably, the additional ribs are located in the rear region. The additional ribs thus prevent liquid from spilling out of the rear while ensuring good rotation of the lid 5 with the container 3 at the connection elements, in particular the pivot connection.

[0068] Preferably, the additional rib extends over the entire rear area, over a length of approximately 32 mm.The additional rib has a thickness between 0.5 mm and 1 mm, typically 0.55 mm, in order to ensure sufficient flexibility.

[0069] The presence of the additional ribs and side flaps 17 , 17 ′ allows preventing the liquid from escaping from the device even in the event of a severe tilt of the container 3 (for example during transport) or in the event of sloshing of the liquid in the container 3 (for example when the container is inserted on the base 1 ).

[0070] Advantageously, the peripheral rib 9 may comprise two straight portions connected by two curved portions. Preferably, the straight portions are thus arranged in the front and rear regions, respectively, ie extend substantially perpendicularly to the longitudinal direction in the front and rear regions, respectively.

[0071] In an embodiment, the corner areas of the peripheral rib 9 are not provided with elements forming obstacles in the closed position between the peripheral rib 9 and the peripheral groove 10 of the lid. This allows ensuring good opening of the lid 5, typically good rotation around the pivot connection.

[0072] Preferably, regardless of the embodiment, the lid 5 cooperates with the opening 4 so as to maintain air permeability in the closed position, so that the container 3 is kept at atmospheric pressure. This ensures that the suction and pressure mechanisms for the liquid between the container and the portable unit function properly. In practice, therefore, preferably no seal exists between the lid 5 and the opening 4 of the container 3, or at least no seal exists at all between the lid 5 and the opening 4 of the container 3.

[0073] The base 1 described above can be used, for example, in a hairdressing device. Such a hairdressing device therefore preferably comprises the base 1 described above, a portable unit separate from the base 1 and a cable 7 fluidly connecting the base to the portable unit.

[0074] Preferably, the portable unit includes a vaporization mechanism that converts a liquid (typically water, beauty product, styling agent, etc.) contained in a container of the base into steam, and applies the generated steam to the hair to improve hair styling. The use of a base 1 such as the one described above improves the vaporization capacity of the hairdressing device, since there is no loss of liquid from the container, and ensures that the portable unit is relatively lightweight and convenient for treating hair. The base may also include a mechanism for adjusting the amount of fluid.

[0075] Such a hairdressing device may typically be a hair straightener or a hair curler for arbitrary shaping of hair, wherein the portable unit comprises two arms movable relative to each other between a close configuration for treating hair, during which steam is sprayed onto the hair to be treated, and a separate configuration for inserting the hair to be treated between the two arms.

[0076] In an embodiment, the two movable arms are arms that are articulated and pivoted at a hinge so that the two arms form a clamp. Each arm may include a treatment surface, the two treatment surfaces provided by each arm of the hair cutting device facing each other so that a hair strand can be clamped between the two treatment surfaces in the close configuration.
