Description

The field of technology to which the invention relates

The present invention relates to the field of hair styling appliances and preferably to the field of hair styling appliances that vaporize liquid towards the hair strands, such as, for example, steam hair styling appliances.

More specifically, the invention relates to the field of hair styling appliances, comprising an evaporator device configured to disperse the evaporated liquid in the direction of the hair strand, a main body, a container configured to remove, accommodate the liquid to be evaporated in it and fix it on the main body so that to be connected to the evaporator device for supplying the liquid to be evaporated therein.

The invention also relates to the field of the art of containers for hair styling devices and, in particular, to containers made with the possibility of placing in them the liquid to be evaporated and fixed on the main body of the hair styling device, said container being capable of being connected to the evaporation device of the device for hair styling, configured to evaporate the liquid and disperse it in the direction of the hair strand.

State of the art

Numerous hair styling devices are known which vaporize liquid towards the hair. In fact, evaporating the liquid onto the strand of hair during styling is known to increase styling efficiency and improve results.

In order to carry out this vaporization, the known hair styling devices comprise a container for containing the liquid to be vaporized. This container is usually removable from the main body of the hair styler in order to facilitate its filling operation. Thus, the user must often, usually at least once before each styling operation, remove the container from the main body of the appliance, fill it with liquid (for example, water), and then connect the container to the main body of the hair styling appliance to supply liquid to be evaporated.

These hair styling devices generally satisfy their users, in particular with regard to the resulting styling. On the other hand, they nevertheless have certain drawbacks or risks when handling them, and in particular during the operations of connecting or disconnecting the container from the main body of the device.

Indeed, if the container is not properly connected to the main body of the appliance, there is a risk of liquid escaping during the laying operation. These risks are particularly increased by the fact that the stacking devices in question are intended to be grasped by the user and to carry out the numerous movements associated with the stacking operations. In addition, the container may accidentally detach from the hair styler. These leaks or disconnections can cause inconvenience to the user, ranging from, for example, simply getting the clothes wet to the risk of electric shock, the hair styling devices in question are usually electrical devices.

To limit this type of risk, various principles have been proposed for attaching the container to the main body of the hair styler.

The first known solution consists, as seen, for example, on many commercial devices or as shown in WO 2017008413, in attaching the container to the main body of the hair styler by sliding: the container must then slide inside the main body so that it can be attached and disconnect. In this case, the retention of the container is partially ensured by friction in the direction of sliding. However, this solution turns out to be particularly restrictive for the user, who, when he wants to attach or detach the container of his hair styler, must firmly grasp the main body of the hair styler with one hand and firmly grasp the container with the other hand, then provide a significant relative displacement between their elements. so as to connect or disconnect them. Thus, this operation requires the user to use both hands, as well as a significant displacement both in amplitude and in strength (to overcome the force of friction). In addition, as connection or separation operations are performed, parts that rub against each other will wear, play will occur, and the reliability of the connection will decrease over time, which may cause accidental separation over time.

Another well-known solution consists in equipping the main body of the device with an element, the elastic deformation of which ensures the connection and disconnection of the container. Thus, the resiliency of this element, usually the tab, allows both the container to be held in an attached position and the tab to be resiliently deformed by forcibly manipulating the container upon connection or disconnection. This solution proves to be particularly unreliable in terms of capacity maintenance and presents a risk of accidental disconnection. In addition, this solution is not very reliable over time, because as the connection and disconnection operations are performed, the tongue wears out and the connection will have play, which increases the risk of accidental disconnection. In addition, there is a high risk of fatigue failure of the tongue due to the deformation force, and therefore the container can no longer be held by the main body. Thus, the reliability and durability of this solution seems to be limited.

Therefore, there is a need to improve existing devices, in particular, at the level of connection of the container with the main body of the device.

Disclosure of the essence of the invention

The aim of the present invention is to overcome the aforementioned disadvantages.

The technical problem to be solved by the invention is to provide a container for a hair styler that is particularly reliable and durable.

The technical problem to be solved by the invention is to provide a hair styler which is particularly easy to handle, in particular during connection and disconnection of the container with the main body of the hair styler.

The technical problem to which the invention is directed is to provide a hair styler that is particularly intuitive to handle and ergonomic, in particular during connection and disconnection of the container from the main body of the hair styler.

The technical problem to be solved by the invention is to provide a hair styler which is particularly compact and lightweight.

These technical problems can be solved by a container designed to contain the liquid to be evaporated therein and attached to the main body of the hair styler, said container being able to be connected to the evaporator device of the hair styler, configured to evaporate the liquid and disperse it. in the direction of the hair strand, characterized in that the container contains a movable fastening device containing at least one fastening means, made so as to correspond to at least one mating fastening means, which is part of the main body, for attaching the container to the main body, and said movable fastening device is movable between the first position, which secures the container to the main body, and the second position, which allows the user to connect or disconnect the container from the main body.

These technical problems can also be solved by a hair styler comprising an evaporator capable of evaporating liquid and dispersing it in the direction of the hair strand, a main body, a receptacle configured to take off, accommodate the liquid to be evaporated therein and attach to the main body. housing so as to be connected to an evaporator for supplying the liquid to be evaporated therein, characterized in that the container corresponds to the foregoing description.

Thus, the invention relates to two separate products, in this case a container for a hair styler and a hair styler, having a relationship with each other, since the first is intended to be connected to the second.

Preferably, the liquid is water. However, the invention is not limited to this particular liquid, and the liquid may, for example, be an oil, a cosmetic product, or any other liquid product that can be applied to the hair to treat it or enhance the styling operation. Optionally, the liquid may be a mixture of water and another product, such as a cosmetic product.

The expression "evaporation" can be understood here in the broadest sense. Thus, it means any type of liquid release, regardless of its nature, form or condition. Thus, for example, a liquid can be evaporated by being dispersed into a plurality of small droplets, preferably microscopic in size, such as from a spray bottle.

Preferably, the expression "evaporation" can also be understood in its strict physical sense, that is, as an operation causing the transformation of a liquid into vapor. In other words, the expression "evaporation" can mean a change of state: a liquid changes from a liquid state to a gaseous state. For example, in the preferred case where the liquid is water, this transformation of state, ie this evaporation, occurs when the liquid reaches a temperature of 100° C. at normal atmospheric pressure.

By "receptacle" is meant any type of container which can contain a liquid, preferably water, in a sealed manner. Preferably, the capacity of the container is from 5 ml to 500 ml, and preferably from 15 to 100 ml. Preferably, the container is made of plastic. Preferably, the container comprises a top casing and a bottom casing joined together in a permanent manner (eg, by gluing or welding).

The container is removable, which means that it can be connected or disconnected (or attached or detached) as desired to the main body of the hair styler without damaging the container or the main body.

In particular, the container may occupy an attached position. In this position, the container is attached to the main body of the hair styler: in this case, the container is integral with the main body, preferably sealed to the main body. Such an attached position allows the liquid contained in the container to be supplied to the styling tool, so that the evaporation device vaporizes the liquid and then disperses it towards the hair strand.

The container can also take a detached position. In this position, it is not integral with the main body. Preferably, the container is independent of the main body and can be freely and easily manipulated by the user, for example, to fill the container, clean it, etc.

A movable fastening device is preferably understood to mean any movable device or means, ie movable in several positions, allowing inter alia to attach (ie to fix) a container to or on the main body of the hair styler. To this end, the movable fastening device according to the present invention comprises at least one fastening means configured to match at least one mating fastening means, which is part of the main body, for attaching the container to the main body. Thus, two mating fastening means are realized between them: on the one hand, a fastening means on a movable fastening device, preferably a pin-type fastening means, and, on the other hand, a mating fastening means on the main body of the hair styler, preferably a female mating fastening means. type. Said at least one fastening means of the movable fastening device and at least one mating fastening means of the main body will interact with each other to provide fastening, i.e. fixation, between the container and the main body. Preferably, the movable fastener includes two fasteners configured to match two mating fasteners that are part of the main body to allow the container to be attached to the main body at two different points, which enhances the mechanical resistance to attachment.

The fastening device according to the invention is movable between a first position allowing the container to be attached to the main body and a second position allowing the user to connect or disconnect the container from the main body. In other words, the first position of the movable fastening device corresponds to the attachment position of the container as described above. The second position of the movable fastening device corresponds to the position of detachment of the container, as described above. Thus, thanks to the movable attachment device according to the present invention, the user can easily and quickly control the movement of the container from its attachment position to its release position, or vice versa. In addition, a movable holding device is built into the container, which allows the user to operate it with the same hand as the hand holding the container. The movable fastening device allows the container to be moved from the attachment position to the detachment position in accordance with the requirements of the user. Thus, the user can attach or detach the container with one hand. In particular, only the conscious action of the user on the movable attachment device (he must cause it to move between two positions) allows the container to move from the attachment position to the detachment position, which prevents the container from accidentally detaching from the main body of the hair styler. This greatly increases the comfort and safety of using the hair styling tool.

A hair styling appliance is understood to mean any type of appliance that enables the user to perform a hair styling operation on hair (or possibly fur, for example in the case of animals). For example, a hair styler can be a straightener to straighten hair, a curling iron (or "curler" as the English term is) to create curls or waves, or an all-in-one device that allows for several different styles.

According to one embodiment, the hair styler comprises a first shaft hinged to a second shaft so as to form a clip movable between an open position and a closed position. The open position allows the user to insert a strand of hair into the appliance, while the closed position allows the user to apply pressure to and preferably heat the hair, shaping it, generally smoothing it. Thus, the device is a hair straightener, a device well known in itself, which will not be described in detail here. In particular, this type of device comprises at least one heating surface for treatment, and preferably two, located at the end of the rod (or each rod) and made with the possibility of contact with the hair to transfer heat to them.

The main body preferably denotes a portion of the hair styler capable of receiving a container therein. According to one embodiment, the main body contains the vaporizer and preferably the first and second rods. However, an embodiment may be envisaged in which the hair styler comprises a main body containing a removable container and an additional body containing, in particular, a vaporizer and preferably first and second rods. In this case, the main body and the additional body will be connected together by a cord configured to transfer the liquid contained in the container of the main body to the additional body.

Preferably, the main body includes a recess shaped to match at least a portion of the container shape and configured to receive at least a portion of the container therein when said container is in an attached position, said recess containing said at least one reciprocal fastener. Thus, the container is at least partially located inside the main body of the hair styler, which allows, on the one hand, to limit the overall size of the hair styler, and on the other hand, to ensure that the container is properly held in its attachment position.

According to a preferred embodiment, the movable attachment device comprises at least one button configured to be directly activated by the user to move the movable attachment device from a first position to a second position or vice versa. This makes the use of the movable attachment device and hence the hair styler particularly simple and intuitive. Preferably, the button is a push button that is operable to be activated by a finger of the user's hand. Preferably, the movable fastening device comprises two buttons which allow the distribution of force and hence improve the ergonomics of the container and the hair styler. Preferably, the two buttons are coaxial and oriented in opposite directions, allowing the user to activate them with a squeezing motion between two fingers, such as thumb and forefinger. Indeed, this is a natural and intuitive movement for people who seek to control an object.

According to a preferred embodiment, the movable fastening device is movable relative to the container. In other words, actuation of the movable fastening device will cause it to move relative to the container, which will remain fixed. This mode of movement of the movable fastening device allows you to combine simplicity, reliability and ergonomics. Indeed, this embodiment enables the user to place the container in the palm of the hand while simultaneously bringing the movable fastening device into translation with one or more fingers of that hand.

Preferably, the container extends in the longitudinal direction along the first axis, and said movable fastener is movable relative to the container along a second axis perpendicular to said first axis. The possibility of translational movement perpendicular to the longitudinal axis of the container makes it possible to obtain a particularly ergonomic container, since a minimum of effort is required to hold the container in the hand. Indeed, the longitudinal axis of the container is located on the palm of the hand, providing excellent support for the container, and the translational movement of the movable fastening device, perpendicular to the longitudinal axis, is thus quite well oriented relative to the movement of the thumb and/or index finger of the hand holding the container.

According to this preferred embodiment, the movable fastener comprises a translation guide, the container comprising a reciprocal translation guide, said translation guide and said responsive translation guide cooperating with each other so as to guide the movable fastener in translation inside the container. Thus, the translational movement of the movable fastening device is limited to one translational movement which is guided by the container itself. This ensures easy movement, good ergonomics and intuitiveness for the user, who can thus avoid mishandling.

However, according to this preferred embodiment, the movable fastening device preferably comprises a first locking device in a first position, wherein the container comprises a first mating locking device in a first position, said first locking device in a first position and said first mating locking device in a first position interact with each other so as to prevent movement of the movable fastening device beyond the specified first position. Thus, the translational movement of the movable fastening device is limited by the container itself in order to prevent it from going beyond the first position. This ensures easy movement, good ergonomics and intuitiveness for the user, who can thus avoid mishandling. In addition, the movable fastening device preferably comprises a second locking device in a first position, and the container contains a second reciprocal locking device in the first position, and said second locking device in the first position and said second reciprocal locking device in the first position interact with each other so that provide the ability to prevent movement of the movable fastening device beyond the specified first position. Thus, the translational movement of the movable fastening device is doubly limited by the container itself. This provides good mechanical strength with two locking points and in particular eliminates any risk of accidental detachment of the movable fastening device from the container.

However, according to this preferred embodiment, the movable fastening device preferably comprises a locking device in a second position, the container having a mating locking device in a second position, said locking device in the second position and said mating locking device in the second position cooperating with each other so to prevent movement of the movable fastening device beyond said second position. Thus, the translational movement of the movable fastening device is limited by the container itself in order to prevent it from going beyond the second position. This ensures easy movement, good ergonomics and intuitiveness for the user, who can thus avoid mishandling.

Finally, when the above two preferred designs are combined within this preferred embodiment, the movement of the movable fastening device is completely limited to translational movement between the first and second positions. This ensures easy movement, good ergonomics and intuitiveness for the user, who can thus avoid mishandling.

According to one embodiment, the first position of the movable fastening device is the rest position. In other words, the movable fastening device, naturally or by default, is stably held in its first position, that is, in a position that allows the container to be attached to the main body of the hair styler. This greatly increases the safety of using the device, because without any action on the part of the user, the container remains securely attached to the main body of the hair styler. To this end, the movable fastening device preferably includes an elastic return device, said elastic return device being preferably a helical spring, which ensures reliability, strength and low cost of the structure. However, any other suitable means for bringing the first position to the rest position can of course be provided, such as, for example, a ferromagnetic device. In the preferred case where the movable attachment device comprises two buttons, the resilient return device is positioned between the two buttons so as to repel and separate the latter. The result is a simple, inexpensive, reliable and mechanically very efficient design. Preferably, the movable fastening device comprises a socket adapted to accommodate a resilient return device. Thus, this socket provides, on the one hand, limiting the size of the movable fastening device due to the integration of the elastic return device, and on the other hand, provides guidance and support of the specified elastic return device during movements, which increases overall reliability. When the movable fastening device is in the second position, the two buttons are preferably in contact, which allows the formation of another locking device in the second position, in order to properly perceive the forces applied by the user to the buttons. This enhances the mechanical strength of the movable fastening device and the reliability of the container.

According to one embodiment, the container comprises an additional fastening device configured to interact with a complementary additional fastener that is part of the main body when the container is in the attachment position. Thus, two further additional fastening means can be implemented to improve the attachment of the container to the main body of the hair styler: on the one hand, an additional fastening device fixed, i.e. fixed and non-deformable, preferably a pin-type fastening device on the container, and, on the other side, a mating additional fastening means on the main body of the hair styler, preferably a mating fastening means of a socket type. Said fixed additional fastening device and the mating additional fastening means will then interact with each other to ensure attachment, i.e. fixation, between the container and the main body. Preferably, said fixed additional fastening device and mating additional fastening means are located parallel to the longitudinal axis of the container, wherein said at least one fastener and mating fastening means are located perpendicular to the longitudinal axis of the container. This allows the attachment points to be well distributed between the container and the main body and hence improves the mechanical resistance of the attachment.

According to one embodiment, the container comprises at least one guide device configured to cooperate with at least one mating guide device of the main body when the container is in the attachment position. In other words, two reciprocal guides are provided to improve the fastening of the container on the main body of the hair styler, as well as to facilitate the operations of connecting and disconnecting the container by guiding the movement of said container: on the one hand, a guide device, preferably of a socket type, on the container, and on the other hand, a reciprocal guide device, preferably of a pin type, on the main body, and preferably included in the recess.

Implementation of the invention

An embodiment of the invention illustrated by the various drawings is an embodiment in which the hair styling appliance that is the subject of the invention is a steam hair straightener. Thus, container 2, which is also an object of the invention, is a container for a steam hair straightener. However, without departing from the scope of the invention, other embodiments could be envisaged, such as, for example, a steam curling iron (or a curling device, as the general expression is).

As shown in FIG. 1, the hair styler comprises a first shaft 11 connected to a second shaft 12 via a hinge 13 to form a clip movable between an open position and a closed position. The first and second rods 11, 12 form the gripping means for the user's hand. To do this, they preferably form, at least over part of their length, a handle that forms a grip zone. The hair styler in the closed position is shown in FIG. 1. Further, essentially at the end of said first and second rods 11, 12 is a hinge 13. The configuration and operation of this type of device is well known per se, so they will not be described in more detail. It is known, for example, that each of said first and second rods 11, 12 comprises a heat treatment surface configured to contact hair. These processing surfaces are located at the end of each of said first and second rods 11, 12, opposite the hinge 13. The hinge 13 is usually an axis around which said first and second rods are mounted.

As shown in FIG. 1 and 2, the hair styler comprises a main body 1 capable of receiving a container 2, as will be described in detail below. In other words, the container 2 is configured to be connected to the main body 1. According to the embodiment shown, the main body 1 comprises said first and second rods 11, 12. a body separated from the main body 1, in which the container 2 is placed. Then the additional body may contain the said first and second levers 11, 12 and the said hinge 13. Then the main body 1 and the additional body will be connected to each other by means of a cord for transferring fluid from containers 2 of the main part 1 of the body to the additional body, or rather, for example, to the first rod 11.

As shown in FIG. 2, the main body 1 preferably includes a recess 111, i.e. a space formed inside the main body 1, the shape of which is responsive to at least part of the shape of the container 2. In other words, the recess 111 forms a concave recess for at least a part of the container 2. Thus thus, the recess 111 is configured to accommodate at least a portion of the container 2 when said container is in the attached position, as will be described in detail below.

Preferably, the main body 1, or more specifically the recess 111, comprises at least one reciprocal guide 114, and preferably two reciprocal guides 114, as shown in FIG. 2. Then said at least one response device 114 may be in the form of a semicircular pin.

The hair styler comprises a container 2 configured to contain an evaporable liquid, for example, preferably water. The container 2 is removable, i.e. the container 2 is detachable and removable from the hair styler as shown in FIG. 2, which shows the main body 1 of the hair styler after the container 2 has been removed. Thus, the container 2 is capable of being connected to the main body 1 of the hair styler.

The container 2 can be in an attachment position as shown in FIG. 1, in which it is integrated into the main body 1 of the hair styler precisely because it is located at least partially inside the recess 111. This makes it possible to create a particularly compact hair styler with a container built into the first shaft 11. Attachment position container 2 corresponds to the working position of the hair styling device.

The container 2 can also be in a detachable position, as shown in FIG. 2-8, in which it is separate and independent from the main body 1 of the hair styler. When the container 2 is in the detachable position, the user can fill it, in particular after removing the filler cap 26 shown in FIG. 5 and 6. More specifically, as shown in FIG. 4, the filler cap 26 includes a filler cap 261 configured to close the filler opening of the container 2 and an air outlet cap 262 configured to seal the air outlet of the container when it is filled. Indeed, in order to facilitate the filling operation, more precisely, to ensure that the container 2 is maintained at atmospheric pressure during its filling, the container 2 contains two openings: one of a larger diameter, allowing liquid to flow through it, and the other of a smaller diameter, providing ventilation, even if the filler hole is completely blocked by liquid, a funnel or any other filling pipette.

As shown in FIG. 3, the container is longitudinally elongated along the first axis X-X', i.e. the container 2 has an overall elongated shape such as a substantially rectangular shape with rounded corners. Indeed, such an elongated shape is particularly suitable for allowing the container 2 to be inserted into the main body 1 and in particular into the first stem 11, as shown in FIG. 1 while maximizing the capacity of the container 2. Preferably, the first rod 11 extends parallel to the first axis X-X'. Preferably, the first rod 11 extends along the first axis X-X'. Then, in this preferred case, as shown, the container 2 can extend more than half the length of the first rod 11, which allows the capacity of the container 2 to be maximized.

The container 2 also preferably includes a connection device 25 shown in FIG. 5 configured to match the mating connector 15 shown in FIG. 2 and located in the main body 1, and more specifically in the recess 111. In these drawings, the connector 25 is a male connector, in this case the section of the tube protruding from the container 2, while the mating connector 15 is a female connector, in this case, a hole. When the container 2 assumes its attachment position, said connection devices 25 and the mating connection device 15 cooperate in a hermetic manner so as to allow the liquid contained in the container 2 to enter the main body 1 of the device, and more specifically, the evaporator device, as will be described in detail. below. The connection device 25 is preferably located at the longitudinal end of the container 2, as shown in FIG. 5 and extends in the longitudinal direction parallel to the first axis X-X'.

As shown in FIG. 4, the container 2 preferably includes an inlet tube 251 sealed to the connection device 25. The inlet tube 251 freely passes inside the container 2 and contains at its free end an inlet end 252, the mass of which is greater than the mass of the inlet tube 251. This provides the effect of gravity to the inlet tube 251 where the liquid itself moves under the action of gravity during the movement of the hair styler. This ensures good absorption of the liquid inside the container 2, regardless of its filling level and position in space. The inlet tube 251 is free inside the container 2, i.e. it is flexible and can move inside the container 2. In combination with the ballasted inlet end 252, this solves the problem of some existing containers that do not completely suck the liquid: in other words, they cannot be emptied, the suction becomes impossible, for example, when the amount of water was halved. This would lead to insufficient autonomy of a device containing such a capacity.

The container 2 also preferably includes a ventilation device 27 shown in FIG. 4-6 and configured, on the one hand, to prevent leakage of liquid from the container 2, and on the other hand, to maintain atmospheric pressure in the container 2. This ventilation device 27 solves the following technical problem. When liquid is sucked in through the inlet tube 251, the amount of liquid inside the container 2 is reduced. However, the container 2 is sealed, so that the amount of liquid sucked in cannot be replaced by air. This leads to the creation of a vacuum inside the container 2 when the liquid is sucked. After some time, the vacuum is so great that the suction of the liquid becomes impossible. In this case, it becomes impossible to suck up all the liquid contained in the container 2, which limits the autonomy of the hair styler containing the container.

The ventilation device 27 counteracts this phenomenon by allowing air to enter the inside of the container 2 as the amount of liquid inside the container 2 decreases, preventing the liquid from escaping the container 2.

As shown in FIG. 4, the ventilation device 27 includes an umbrella or mushroom valve. This shape, due to the weight of the liquid pressing on the cap or head of the valve, ensures that the valve is held in a retracted state and, therefore, the leakage of liquid from the container 2 is prevented. On the other hand, when the pressure inside the container 2 drops, the external atmospheric pressure pushes the valve base, despite by the weight of the liquid, which allows air to enter the inside of the container 2. When the pressure inside the container 2 is balanced with the external pressure (atmospheric), the valve returns to its original position due to the weight of the liquid, as explained above.

As shown in FIG. 3 and 4, the container 2 comprises an upper casing 21 and a lower casing 22 which are sealed together and preferably permanently, that is, they are not detachable, for example by gluing or welding. Such an assembly solves the problem of mounting the container 2 by greatly facilitating or even simply enabling the installation of various components inside the container, and in particular the installation of the inlet tube 251 described above.

As will be apparent, each of the devices described above, and in particular the inlet tube 251 and the ventilation device 27, provide a solution to a particular technical problem and may therefore constitute inventions in their own right.

As shown in FIG. 5 and in more detail in FIG. 7, the container 2 preferably includes a guide frame 23, which itself preferably contains various rods, allowing such various guidance and attachment functions to be provided, as will be described in detail below. The guide frame 23 is preferably located at the longitudinal end of the container 2, preferably opposite the connecting device 25.

The hair styler includes an evaporative device configured to vaporize liquid and disperse it in the direction of the hair strand. The evaporator device may, for example, comprise an evaporator chamber in which, under the influence of heat, the liquid in the container 2 is converted into vapor. The steam is then dispersed in the direction of the hair strand, for example through the distribution holes. Such a device is well known per se and therefore will not be described in detail. Another evaporator device may be, for example, a fine atomization system that will convert the liquid into fine droplets, like an atomizer, without changing the state of the liquid.

Thus, the container 2 is configured to be connected to the evaporator device of the hair styler, configured to vaporize the liquid and disperse it in the direction of the hair strand. Then the container 2 will supply the liquid to be evaporated to the specified evaporation device. Preferably, the connection is airtight and is made in particular by means of a connecting device 25 and a mating connection device 15. The hair styler, and more preferably the main body 1, may also contain a flow device such as, for example, a pump, and preferably a peristaltic pump which sucks up the liquid placed in the container, thanks to the inlet tube 251 for pumping the liquid to the evaporator device.

According to the invention, the container 2 comprises a movable fastening device 3, as shown in FIG. 1, 3, 4, 6 and 8. In other words, the movable fastening device 3 is located on the container 2, i.e. the movable fastening device 3 is made integral with the container 2. This provides better ergonomics for the user of the container 2 and, therefore, the instrument for hair styling, because it allows you to simultaneously manipulate the container 2 and the movable fastening device 3 with one hand.

As shown in FIG. 10, the movable fastening device 3 comprises at least one fastening means 333. More specifically, the movable fastening device 3 preferably includes a lug 33 which in turn includes at its end a hook forming a rib that protrudes from the lug 33 and is formed with the possibility of attaching to the counterpart; said rib then forms a fastener 333. In other words, the fastener 333 is a pin fastener whose shape is substantially rectangular. Preferably, as shown, the movable fastening device 3 comprises two fastening means 333 which increase the attachment points between the container 2 and the main body 1 and hence increase the mechanical strength of the attachment. The two fasteners 333 are preferably symmetrical about a median plane P perpendicular to the container's first axis X-X', as shown in FIG. 10.

Said at least one fixing means 333 makes it possible to connect the container 2 to the main body 1, that is to say, hold the container 2 in the attachment position. Preferably, the fastening means 333 is rigid, that is, cannot be deformed. This feature ensures mechanical strength between the container 2 and the main body 1 and thus eliminates any risk of accidental release. In addition, unlike presently known container attachment methods that operate on the basis of elastic deformation of such an attachment device, the rigidity of the attachment means 333 according to the invention provides the mechanical strength of the attachment over time, i.e. even after repeated use. Indeed, the risk of failure of the fastener 333 due to fatigue is eliminated. Thus, the reliability and durability of the fastener 333 and hence the container 2 and thus the hair styler are improved.

As shown in FIG. 2, the main body 1, and in particular the recess 111, comprises at least one mating fastening means 11. Said fastening means is responsive to the fastening means 333, that is, it cooperates with the latter so as to allow the container 2 to be attached. As shown in fig. 2, the mating fastener 112 is preferably a female fastener, for example, containing a substantially rectangular cavity. A pin fastening means 333 will then be placed in this mating fastening means 112 to provide fastening. Preferably, the substantially rectangular shapes of said fastening means 333 and mating fastening means 112 provide a distribution of mechanical strength along a certain length, which improves the mechanical resistance, in particular to tear, of fastening the container 2 to the main body 1. Thus, said at least one fastening means 333 is configured to match said at least one mating fastener 112, which is part of the main body 1, so as to secure the container 2 to the main body 1. Preferably, said recess 111 includes said at least one mating fastener 112, as shown in FIG. 2, preferably at an angle. Preferably, the main body includes two mating fasteners 112 located on a second axis Y-Y' perpendicular to the first axis X-X'.

The movable attachment device 3 is movable between a first position allowing the container 2 to be attached to the main body 1 and a second position allowing the user to connect or disconnect the container 2 from the main body 1. In other words, to move the container 2 from the attachment position to the detachment position, the user must move the movable fastening device 3.

More specifically, in order to bring or hold the container 2 in its attachment position, it is necessary to install or hold the movable attachment device 3 in its first position. Thus, the first position of the movable fastening device 3 corresponds to the attachment position of the container 2 and therefore to the operating position of the hair styler. In order to securely attach the container 2 and limit user intervention, it is preferable that the first position of the movable fastening device 3 be the rest position. In other words, without any action on the part of the user, the movable attachment device 3 is naturally in its first position, i.e., in a position for attaching the container 2 to the main body 1 of the hair styler.

Conversely, to bring the container 2 into the release position, it is necessary to move the movable fastening device 3 to the second position, which will cause the container 2 to be released, as will be described in detail below.

In the various drawings, the movable fastening device 3 is shown in detail in the second position.

Preferably, as shown in the various drawings, the movable attachment device 3 comprises at least one button 31, and preferably two buttons 31. By a button is meant any part intended to be operated directly by the user, preferably by the hand and more particularly at least one finger. user. Preferably, button 31 is a push button that is operable with one finger of the user. Said at least one button 31 is connected, preferably rigidly, to the fastening means 333, so that when the user presses said at least one button 31, this causes the fastening means 333 to move, more specifically, removes the fastening means 333 from the mating fastening means 112 (that is, said fastening means 333 and mating fastening means 112 no longer interact with each other) and therefore move the movable fastening device 3 from its first position to its second position, or vice versa. In other words, the movable fastening device 3 can then move between said first and second positions.

Preferably, the movable fastening device 3 is translated relative to the container 2, i.e. the movable fastening device 3 is moved in accordance with the translational movement, and preferably only translational movement, relative to the container 2, which then forms a fixed frame of reference.

Preferably, as shown in FIG. 8, said movable fastener 3 can be translated relative to container 2 along a second axis Y-Y' perpendicular to said first axis X-X'. In other words, the translational movement of the movable fastening device 3 then takes place perpendicular to the longitudinal direction of the container 2. In the preferred case, when the movable fastening device 3 comprises two buttons 31, this means that the two buttons 31 are movable along the second axis Y-Y' . This configuration represents a noticeable improvement in ergonomics, since the user can then manipulate the container 2 and its fastening system, namely the movable fastening device 3, with one hand. More specifically, the user may place the container 2 on the palm of the hand with the first axis X-X' substantially perpendicular to the user's hand. The movable fastening device 3 and in particular the buttons 31 are in this case in an ideal position to be operated directly by the thumb and forefinger of the hand of the user holding the container.

As shown in FIG. 9 and 10, the movable fastening device 3 has a symmetry plane P perpendicular to the second axis Y-Y'. In other words, the plane P may include the first axis X-X'. Thus, the movable fastening device 3 is perfectly symmetrical with respect to the plane P. The movable fastening device comprises two subassemblies located on both sides of the plane P and symmetrical with respect to the plane P. Thus, in the following description, only one of the subassemblies will be described, while the other subassembly has mirror symmetry with the first.

The lug 33 of the movable fastening device 3 is integral with said button 31. Preferably, the lug 33 is material-continuous with the button 31, i.e. it is made of the same material and can be made at the same time as the button, for example by machining or molding . However, the tab 33 can also be connected to the button 31, for example by welding. The tab 33 is preferably in the shape of an inverted T. The vertical bar of the T is integrated with the button 31, while the horizontal bar of the T contains a fastener 333.

Preferably, the movable fastening device 3 comprises a translation guide 331, preferably formed by the vertical crossbar of the T-shaped portion of the tab 33. In this case, the container 2 comprises a reciprocal translation guide 231 shown in FIG. 7, preferably formed by a rod of the guide frame 23. Said translation guide 331 and the reciprocal translation guide 231 then cooperate with each other so as to guide the movable fastening device 3 in translation within the container 2, and more precisely within the guide frame 23.

Preferably, as shown in FIG. 8, the translational guidance is carried out by a sliding joint, preferably formed by a vertical bar T, moving within the U-shaped space formed by the guide frame 23, as shown in FIG. 7 and 8 and a horizontal bar T which rests on U, the length of the horizontal bar T being longer than the hole U. Preferably, the U formed inside the guide frame 23 is open to the outside, and the second axis YY' is the axis of symmetry for U- shaped space of the guide frame 23. In addition, the button 31 is also designed to press U of the guide frame 23. Thus, the specific shape of the movable fastening device 3 and, in particular, its base 33, in combination with the reciprocal shape of the guide frame 23, provides the formation a sliding joint for guiding the movable fastening device 3 in translation within the guide frame 23 of the hair styler container 2 . Without departing from the scope of the invention, a similar direction of translation can be provided, which can be achieved using a dovetail device. Preferably, the sliding joint has a Y-Y' axis.

Preferably, the movable fastening device 3 includes a first locking device 341 in a first position, as shown in FIG. 9 or 10. More specifically, in plan view, the button 31 is shaped like a T, with the horizontal bar of the T being the portion that the user will actuate with their finger, as shown in FIG. 9. The button 31 preferably includes a first protrusion 34 that protrudes from the vertical bar of the T formed by the button 31 in a direction similar to that of the tab 33. Preferably, the protrusion 34 and tab 33 extend in parallel directions, and preferably in the same direction. Preferably, the first protrusion 34 comprises a substantially flat surface perpendicular to the vertical bar of the T formed by the button 31, said surface defining said first locking device 341 in the first position. Thus, said first locking device 341 in the first position is preferably parallel to the plane P.

Preferably, the button 31 includes reliefs to improve the quality of contact between the button 31 and the user's finger. These reliefs also allow the user to visually indicate where to place a finger to release container 2.

Preferably, the container 2 includes a first mating lock 232 in a first position, as shown in FIG. 7. More specifically, said first mating locking device 232 is included in a first position in a guide frame 23 which forms a substantially rectangular window at this location. Then said first reciprocal locking device 232 in the first position is formed by a rod parallel to the first axis X-X'. Preferably, said rod has a rectangular or square cross section to provide substantially flat side surfaces, and in particular a side surface substantially parallel to the first locking device 341 in the first position.

Then said first locking device 341 in the first position and the first reciprocal locking device 232 in the first position 232 cooperate with each other so as to prevent movement of the movable fastening device 3 beyond the said first position, in other words, to ensure that the first position of the movable fastening device 3 stops. As shown in FIG. 7-10, the interaction in question is preferably a plane-on-plane interaction. This allows for a good contact that distributes loads well and therefore guarantees a secure, strong and durable stop in the first position. This ensures that the translational movement of the movable fastening device 3 is limited so that said movable fastening device cannot go beyond its first position. A good quality of the abutment is all the more important since, as explained above, the first position can correspond to the resting position, i.e. the position that the movable fastening device 3 very often occupies.

Preferably, the movable fastening device 3 comprises a second locking device 351 in a first position, shown in particular in FIG. 9 and 10. More specifically, the button 31 preferably includes a second protrusion 35 which projects from the vertical bar T formed by the button 31 in the opposite direction but parallel to the direction of the tab 33. Preferably, the first protrusion 34 and the second protrusion 35 extend parallel but in opposite directions. directions. In other words, said first and second projections 34, 35 extend on either side of the vertical bar of the T formed by the button 31, as shown in FIG. 9. Preferably, the second protrusion 35 is parallel to the plane P.

Preferably, the container 2 includes a second mating lock 233 in the first position shown in FIG. 7. Said second mating lock can then be formed by a recess wall formed directly in the upper shell 21 of the container 2. Preferably, the second mating lock 233 extends in the first position in the longitudinal direction parallel to the first axis X-X'.

Then, said second locking device 351 at the first position and the second reciprocal locking device 233 at the first position cooperate with each other so as to prevent movement of the movable fastening device 3 beyond the said first position, in other words, a method of forming the abutment of the first position of the movable fastening device 3 is obtained. Here, too, the interaction is preferably a plane-on-plane interaction, which therefore has the same advantages as those mentioned above. The fact that the movable fastening device comprises two locking devices 341, 351 in the first position, each of which interacts with two mating locking devices 232, 233 in the first position of the container 2, provides the formation of two stops of the first position of the movable fastening device 3. This allows good to distribute the contact pressure between the two stops and, consequently, increases the strength, reliability and durability of the movable fastening device 3. In addition, each of these stops ensures that the button 31 is held as a whole with the container and prevents accidental removal of the movable fastening device 3 from the container 2.

Preferably, the movable fastening device 3 includes a locking device 332 in the second position shown in FIG. 10 and preferably formed by tab 33. More specifically, said locking device 322 in the second position is formed by the surface of the tab 33 which is substantially parallel to the first locking device 341 in the first position and preferably parallel to the plane P. Thus, said locking device 332 in the second position and the first locking device 341 in the first position is formed by two parallel stops, which limit the translational movement of the movable fastening device 3.

Preferably, the container 2 includes a reciprocal locking device 234 in the second position shown in FIG. 7. Then the reciprocal locking device 234 in the second position is preferably parallel to the first reciprocal locking device 232 in the first position, for example, due to the fact that it is located on the opposite side of the same rod of the guide frame 23.

Said locking device 332 in the second position and the reciprocal locking device 234 in the second position then cooperate with each other so as to prevent the movable fastening device 3 from moving beyond the said second position to form the second position abutment, in particular when the user presses the button or buttons 31 .

Preferably, as mentioned above, the plane P forms a plane of symmetry for the movable fastening device. Thus, the movable fastening device comprises two buttons 31, two tabs 33, two first tabs 34, two second tabs, two translation guides 331, two locking devices 332 in the second position, two fastening means 333, two first locking devices 341 in the first position, two second locking devices 351 in the first position, each of which is located symmetrically on both sides of the plane P, as shown in FIG. 9 and 10.

Preferably, the movable attachment device 3 comprises a resilient return device 32 as shown in FIG. 9 configured to hold the movable fastening device 3 in its first position. The resilient return device 32 is preferably a coil spring capable of holding the buttons 31 in the extended position. However, without departing from the scope of the invention, other reversible devices may be provided which would allow the buttons 31 to be held in the extended position, ie the movable fastening device 3 to be held in the first position. For example, an electromagnetic device may be provided, wherein the container 2 contains a magnet and each of the buttons 31 is made of magnetic material (or vice versa). Preferably, as shown in FIG. 9, the resilient return device 32 is located between the two buttons 31, which allows a simple design and the use of the resilient return device 32, in this case a helical spring, to transfer all its force to the buttons 31 and only the buttons 31. The movable fastening device 3 preferably includes a socket 312 , configured to accommodate a resilient return device 32 as shown in FIG. 9. This allows the resilient return device 32 to be held in place and guided as it deforms. The socket 312 is preferably formed by a recess which starts from one end of the button 31, in this case from the free end of the vertical bar of the T formed by the button 31, and partially extends inside the button 31, preferably along the second axis Y-Y'. Thus, when the movable fastener 3 is in the second position, the two buttons 31 are in contact, the dimensions of the movable fastener are zero, since it is found to be fully integrated into the socket 312, i.e. inside the buttons 31. This makes it possible to limit the size of the movable fastener device 3. As shown in FIG. 9, the resilient return device extends longitudinally along the second axis Y-Y'.

As shown in FIG. 9, the second axis Y-Y' preferably forms an axis of symmetry for the movable fastening device 3.

As shown in FIG. 8, the first axis X-X' forms the axis of symmetry for the guide frame 23, the plane P preferably forms the plane of symmetry for the guide frame.

The container 2 preferably contains an additional fixed fastening device 221, i.e. fixed and non-deformable, as shown in FIG. 5 and 6, and preferably comprising a tongue of substantially rectangular shape, forming a protrusion of the container in a direction parallel to the first axis X-X'. Preferably, the additional fastening device 221 is located at the longitudinal end of the container 2 and preferably opposite the movable fastening device 3, which is itself located at the other longitudinal end of the container 2. This allows the various points of attachment of the container 2 to the main body 1 to be moved as far as possible, which improves stability and mechanical strength. attaching the container 2 relative to the main body 1. In addition, in the preferred case shown, when the movable fastening device 3 includes two fasteners 333, this provides the container 2 with three points of attachment to the main body 1, which corresponds to an isostatic assembly. In addition, the attachment points can be arranged in a triangular pattern due to the location of the two attachment means 333 on the second axis Y-Y' and the location of the additional attachment device 221 on an axis parallel to the first axis X-X' or possibly on the first axis X-X'. The location of the points of attachment of the container 2 on the main body 1 in the form of a triangle increases the stability and mechanical strength of the fastening between the container 2 and the main body 1, and, consequently, the reliability of the fastening between the two elements.

The main body 1 then contains an additional mating fastener 113 shown in FIG. 2. The additional mating fastening means 113 comprises, for example, a substantially rectangular recess formed inside the main body 1 from a recess 111 in a direction parallel to the first axis X-X'.

Then said additional fastening device 221 and additional mating fastening means 113 are arranged to cooperate with each other when the container 2 is in the attachment position, wherein the additional fastening device 221 is preferably a pin fastening device, and the additional mating fastening means 113 is preferably reciprocal socket fastening device. In the illustrated embodiment, at least one additional mating fastener 113 is used to interact with at least one additional fastener 221, but an increase in the number of these elements can be provided to increase the mechanical strength of the fastening.

As shown in FIG. 5 and 6, the container 2 includes at least one guide device 24 configured to cooperate with at least one mating guide device 114 of the main body 1 when the container is in the attachment position. This makes it possible to provide at least one guide means between the fastening means 333 and the additional fastening device 221, which greatly facilitates the operation of attaching the container 2 to the main body by providing an intermediate guide to the user. In addition, guides 24 and reciprocal guide 114 provide an increase in the mechanical resistance of the attachment when the container 2 is in the attachment position, blocking any translational movement of the container 2 along the first axis X-X'. This makes it possible to unload the fastening means 333 and the additional fastening device 221, which in this case only have to provide an anti-tearing connection along a third axis perpendicular to the first axis X-X'. This increases the strength and durability of the container. The longer the length of the container 2, the larger this intermediate guide point. Preferably, the guiding device 24 is a female guiding device, such as, for example, a hole or, as shown, a side recess in the form of a half hole. The mating guide 114 is a mating pin guide that may be in the form of a half (longitudinally) round pin as shown in FIG. 2. The container 2 preferably contains two guide devices 24 and the main body 1 contains two reciprocal guide devices 114.
