Description

HAIR DYE DISTRIBUTOR FIELD AND BACKGROUND OF THE INVENTION The present invention relates to devices for dyeing hair in general and in particular, with a portable hair dye distributor, which employs a removable cartridge to contain and distribute the dye. It is known how to provide a comb or brush-like device for the manual application of hair dye. Examples of such devices are described in U.S. Patent Nos. 3,457,928 to Kurshenoff, 4,592,376 to Sig ond et al. and 5,297,882 from Kornides. Each of these devices includes an expectorable reservoir containing hair dye. The pressure applied manually to the reservoir aims to force the dye along a duct towards a brush-like dispenser where it is released onto the hair. The squeezing action devices of this type suffer numerous disadvantages. First, the pressure, which can be applied comfortably by the hand, is generally not sufficient to force the hair dyes, which are typically very viscous, along the duct and outward through the openings of distribution. Even if the dye could be distributed in this way, the distribution speed is typically irregular, varying with the instantaneous amount of applied pressure. In addition, a high level of coordination and experience is required to apply and extend the dye while being squeezed tightly on the container. Finally, the reservoir and conduit have a relatively large "dead space, from which the dye can not be ejected by squeezing, which leads to a large amount of dye being wasted, and makes the device difficult to clean. US Pat. No. 5,333,627 to Mehringer, Meheringer provides a syringe-like device in which a piston is advanced by a finger-operated lever, the piston forcing the dye towards an ejection base, which is formed with a number of distribution channels A removable dispensing head with a brush or sponge extension is mounted on the ejection base to align with the distribution channels The Mehringer device offers a partial solution to some the problems mentioned above, providing a more controllable distribution and less waste than the acc squeezable ion described above. However, the device is still difficult to use, since it requires the operation of the lever and the extension movement through the hair simultaneously by the fingers. The difficult operation is further aggravated by the long structure of the syringe body, which should be prevented from sticking out of the head by the use of the device, in addition to the single straight row of distribution channels that requires careful alignment of the device perpendicular to the direction of extension. Additionally, the integrated ejection channels based on the Mehringer device are difficult to clean and therefore prone to clogging with the dye left in previous uses in the device. Therefore, there is a need for a compact and easy-to-use hair dye dispenser that employs a replaceable cartridge that contains and distributes the dye, thus minimizing waste and minimizing cleaning.

DESCRIPTION OF THE PREFERRED MODALITIES The present invention is a hair dye distributor. The principles and operation of a hair dye distributor according to the present invention may be better understood with reference to the drawings and the accompanying description. Referring now to the drawings, Figures 1 and 2 show a hair dye distributor, generally designated 10, constructed and operating according to the teachings of the present invention, for dispensing a fluid hair dye. Generally speaking, the hair dye distributor 10 includes a dispensing container 12 for containing and distributing the dye for p lo. The distribution container 12 has a base 14 hermetically joined to or integrally formed with at least one side wall 16, to define an internal volume 18 of the distribution container 12. The base 14 is formed with an upper surface 20, which is substantially flat and with a lower surface 22, which is formed with a plurality of projecting teeth 24. A number of distribution openings 26 are formed through the base 14 at positions distributed through the base. A piston 28 is configured to fit perfectly in sliding contact with the inner surface of the wall 16 to slide tightly against the base 14.

The dispenser 10 also includes a housing 30 formed with a receptacle 32 configured to removably receive the dispensing container 12. The housing 30 contains a drive mechanism 34 configured to move the piston 28 toward the base 14, thereby distributing the hair dye through the dispensing openings 26. It will be readily apparent that the use of a replaceable dispensing container 12 received by the housing 30, overcomes many problems associated with the known devices, described above. Since the dispensing container 12 is preferably a disposable article for one-time use, the dispensing openings 26 will generally not be obstructed, and will not need to be cleaned after use. At the same time, since the internal volume 18 is immediately adjacent to the distribution openings, the waste of hair dye is minimized. Typically, the piston 28 is also a discarded article although an embodiment of the piston 28 attached to the drive mechanism 34 is also possible. Also, as will be clear from the following description, the preferred embodiments of the distributor 10 are implemented with a device Portable, lightweight, which can be easily fastened and operated by the user without excessively tiring the user's hand, preferably, without requiring the coupling by cables or tubes to any external equipment. The device is preferably driven by a lightweight electric motor included within the housing 30, avoiding excessive weight and large dimensions that fatigue the user's hand. The device provides total control over the amount of dye applied without requiring difficult pumping actions or the like. Before going into the features of the present invention in more detail, it should be appreciated that the present invention is useful in a wide range of applications, in which a fluid is applied to the hair for coloring, dyeing, bleaching or any other treatment. By way of example, the present invention will be described in the context of the application of a hair dye. However, the reference to "dye" should not constitute a limitation of the structure claimed in any way. It should be noted that the term "fluid" is used herein in the description and the claims to refer to any flowing composition or mixture so that it can be distributed through the distribution openings 26 an applied pressure was lowered. Examples of fluids according to this definition include, but are not limited to, liquids, suspensions, gels, creams and pastes or a wide range of thicknesses. Turning now to the characteristics of the distributor 10 in more detail, a particular characteristic of most preferred implementations of the distributor 10, is that the drive mechanism 34 includes a conversion mechanism 36 for converting a unidirectional rotational input to a linear oscillating displacement. . This linear displacement is used to drive the piston 28 to distribute the hair dye. The unidirectional rotational input is preferably provided by an electric motor 38, typically reduced by a gear mechanism 40, although manually operated implementations also fall within the scope of the present invention. The motor 38 is typically powered by one or more batteries 42, which may be of the disposable or rechargeable type. Additionally or alternatively, a connection (not shown) may be provided for the use of an external power supply. The gear mechanism 40 preferably provides a reduction ratio of at least about 100: 1, and preferably at least about 1000: 1. Most preferred implementations provide a ratio in excess of about 10,000: 1 / and typically of about 105: 1. The higher ratio ensures that an electric motor, compact for general purposes, can be used to provide sufficient pressure to more evenly distribute very thick dye compositions. The exact ratio is chosen so as to provide a cycle of about 4-6 minutes for a given engine speed 38. The gear mechanism 40 can be implemented as an independent mechanism connected to a freestanding engine 38. Alternatively, part or all of the gear mechanism 40 can be combined in a single unit with the motor, supplanted where necessary by a supplementary gear mechanism. In any case, the gear ratio referred to herein is the total relationship between the rotation speed of the motor itself in the final stage of the rotational movement before the conversion to linear motion. It will be apparent that many different mechanisms could be used for the conversion mechanism 36. In a more preferred embodiment, the conversion mechanism 36 is configured to generate an asymmetric linear displacement velocity so that, for a given rotation speed of the rotational input , the movement in a first direction is at least an order of magnitude slower than the movement in an opposite direction. This provides a slow, high-pressure driving stroke to distribute the hair dye followed by a faster return stroke to prepare the distributor for a subsequent operation. It should be noted that this feature can also be used to advantage the alternative implementations of the present invention by employing a fixed, reusable distribution container. A particular preferred implementation of the conversion mechanism 36 will now be described with particular reference to Figures 3 and 4A-4D. In this case, the conversion mechanism 36 includes a toothed ratchet collar 44 and a tracer collar 46, mounted coaxially to rotate in mutual relation. The relation of the tracer collar 46 in relation to the ratchet toothed collar 44 generates the asymmetric oscillating linear movement in an axial direction. The principle of this mechanism will be understood more clearly with reference to Figures 4A-4D. The toothed ratchet collar 44 has numerous ratchet teeth 48 that extend axially. Preferably, three teeth 48 are used, which provides mechanical stability to the mechanism at all stages of its movement, as will be clear. In this context, the phrase "ratchet tooth" is used to refer to an asymmetric projection / which is formed between two substantially straight edges or, more accurately in the case of a collar, helical. The tips of the teeth are preferably rounded to facilitate uniform progress of the tracer collar between the edges of the teeth The tracer collar 46 is formed with features configured to follow the serrated contour of the pawl of the ratchet toothed collar 44. Optionally, they could relatively small bearings, rollers or contact portions are used, however, in a preferred embodiment shown here, the tracer collar 46 has ratchet teeth 50 formed to complement those of the pawl ratchet collar 44. In the case shown here, the collar toothed ratchet 44 rotates while remaining fixed against axial movement, while tracer collar 46 remains fixed against rotation, but can be moved axially Figure 4A shows a state in which the toothed collar of ratchet 44 and tracer collar 46 they mate to assume a completely retracted position, which ue corresponds to the initial and final position of each operation cycle. When the toothed collar of ratchet 44 begins to rotate, the less gradually sloping face of each tooth of pawl 48 slides on the corresponding surface of a tooth of pawl 50, thereby forcing tracer collar 46 axially downward as shown in FIG. Figure 4B. When the movement continues, the mechanism approaches the end of its linear movement as shown in Figure 4C, where the teeth 48 and 50 come into contact near their extremities. It is in this state that the preferred attachment with three teeth for each ring provides significant stability advantages. n consequence, when the rotation of the ratchet collar 44 of the ratchet proceeds, the contact is transferred to the gradual return surface of the teeth 48 and 50, providing a relatively rapid axial return stroke of the tracer collar 46, as shown in Figure 4D, until the mechanism returns to the state of Figure 4A with the toothed collar of ratchet 44 rotated through 120 °. It should be noted that the gradual return surfaces of the teeth 48 and 50 can be approximated vertically, ie, parallel to the axis of rotation, to provide the instantaneous return to the initial position actuated by a spring. However, an angle of one or a few degrees avoids a hammering click of the return tracer collar. In the practical implementation of the mechanism shown in Figure 3, the axial alignment of the ratchet toothed collar 44 and the tracer collar 46 are maintained by the engagement of concentric cylindrical sleeves. Specifically, the toothed collar of ratchet 44 is here integrally formed as part of a drive disc 52, which has an internal cylindrical sleeve 54 and an outer sleeve 56. They are in contact, respectively, and an internal cylinder 58 and a sleeve The cylindrical outer 60 is formed integrally with the tracer collar 46. An axially shaped pin 62, and in this case hexagonal cross section, is rigidly joined to, or integrally formed with the housing 30. The pin 62 engages a corresponding axial opening the internal cylinder 58 to immobilize the tracer collar unit against rotation, while leaving it free to move axially. The mechanism is unified by a pair of retracting pistons 64, between which a spring element 66 is retracted. The spring element 66 further assists the return movement of the tracer collar unit. The conversion drive mechanism 36 is typically achieved, either directly, or through an additional step downward gear 68, of the gear mechanism 40 by means of a gear wheel 70 which engages a toothed track 72 around the rotor disc. drive 52. The drive mechanism 34 also preferably includes features to automatically interrupt the operation of the distributor at the end of each cycle of use. For this purpose, a sensor 71 is deployed to provide an end-of-cycle output indicative that the conversion mechanism 36 reached a predefined point in its oscillating linear displacement cycle. In the example illustrated here, the sensor 71 is implemented as a microswitch configured to generate a momentary reset signal when it comes into contact with one of the three drive projections 73, formed on the drive disk 52. This drive mechanism is preferably configured so that this reset signal causes on / off of switch 75 to return to its "off" position, thereby interrupting the operation of motor 38.

Referring now briefly back to Figures 1 and 2, it should be noted that the described implementations of the dispenser 10 allow the use of a particularly ergonomic and practical form of housing 30. Specifically, the housing 30 is preferably formed with a handle 74 configured to be held in the hand of a user. Advantageously, an internal volume of the handle is preferably used to accommodate most or all of the drive mechanism 34. The centralization of the weight of the drive mechanism within the handle serves to optimize the balance and comfort of the dispenser. Another particular advantage of certain preferred implementations of the dispenser is that the receptacle 32 is configured to define an inserted position of the dispensing container 12 as shown, in which the base 14 is substantially parallel to the direction of elongation of the grip 74. This allows the dispenser to be held in a manner similar to a conventional hair brush during use, thus making use of the dispenser 10 convenient for self-application by a non-professional user. Additional features that contribute to the convenience and efficiency of the dispenser 10 are related to the design of the dispensing container 12. First, the dimensions of the dispensing container 12 are preferably chosen so that the dye can be distributed over a relatively large area. large simultaneously, while minimizing the dimension to the top, so that the distributor 10 can be kept as compact as possible. For this purpose, a larger dimension of the designed "length" of the base is preferably at least about twice the "length" defined as the dimension of the side wall 16 measured perpendicular to the length. In a preferred embodiment, in which the base 14 is round, the side wall 16 is, correspondingly, a substantially simple cylindrical wall, the "length" corresponding to the internal diameter of the wall 16. Other characteristics of the distribution container 12 which further contribute to facilitating the use and efficiency of the dispenser 10 relate to the placement and configuration of the dispensing openings 26. Preferably, at least one, and typically all distribution openings 26 are implemented as distribution channels as Length of the projected teeth 24. This ensures effective release of the hair dye down to the root portion of the hair, where it is typically most needed. A further particularly preferred feature is that the distribution openings 26 are distributed substantially around the periphery of the base 14, and more preferably, substantially evenly spaced around a substantially circular line. With at least 6, and preferably between about 8 and about 20, distribution openings, the distribution of the almost uniform dye is made over the perfectly swept area by the distributor 10, independently of the direction in which the distributor moves. As a result, the user need not be in the particular angle at which the dispenser remains in relation to the brushing direction in the dye. In parentheses, it should be noted that the distribution container 12 does not need to assume a symmetrical cylindrical shape. Examples of other possible shapes of the base 14 include, but are not limited to, elliptical, square, rectangular and other regular or irregular polygonal shapes. In addition, although the side walls 16 are typically perpendicular to the base 14, this is not a necessary condition. Similarly, for different applications and types of hair, the design, separation and number of distribution openings can vary considerably,. By way of example, an alternative aperture design employs a single elongated slot along the major part of the base 14 to distribute the dye. Turning now to Figures 5A-5G and 6A-6D, it should be noted that the fluids to be distributed by the dispenser of the present invention are often mixtures of two or more components, which must be stored separately and combined immediately before its use. The disposable dispensing container 12 of the present invention can be easily filled with a ready-to-use composition prepared externally by conventional techniques. However, in a preferred embodiment of the present invention, the dispensing container 12 is used in conjunction with a storage container suitably configured to provide convenient separate storage and mixing of the components immediately before use. Turning first to Figures 5A-5G, these show a storage container 80 configured to store at least one component 82 of the hair dye in an airtight manner. The storage container 80 is configured to removably attach, typically by complementary screw adjustment threads, to the dispensing container 12 in a shape that allows the release of at least one component toward the distribution container 12. The release is achieved preferably providing a frangible barrier 84 to facilitate the release of at least one storage component or container 80 in the distribution vessel 12. The frankable barrier can be implemented as a layer of pre-marked thin sheet metal with expiration or tear lines. The material for the barrier is chosen according to the properties of the material to be stored, and in some cases the use of a silver coating or the like is required. Optionally, a second component of the composition can be stored for use within the distribution container 12, itself. In this case, the upper opening of the dispensing container 12 is sealed by the presence of the storage container 80, while the dispensing openings 26 are preferably sealed externally by means of a removable adhesive tape 86 or the like.

Alternatively, in a preferred implementation, the storage container 80 has a connecting port 88, normally sealed by a screw cap 90 or the like (Figure 5A), which is configured to receive a storage bottle 92 (Figure 5B) to mix the components of the hair dye. This provides a particularly convenient and clean option in which two or more components can be mixed together into the storage container 80 before the ready-to-use composition is released into the distribution container 12. For certain dye compositions , mixing by stirring is not completely effective, so that a stirring motion by direct contact is still preferred or required. To meet this requirement, certain preferred implementations of the present invention further have a mixing element 94 associated with the storage container 80. The mixing element 94 has a handle portion 96, which is preferably peelable, extending from the outside of the storage container 80 and an operative portion 98, shown here as a propellant type element, which extends within the storage container. Manual movement of the handle portion 96, when attached, causes mixing of the contents of the storage container 80. In a preferred option, the mixing element 94 is mounted to allow axial movement between the positions shown in Figures 5C. and 5D. This provides a push-action releasing mechanism for breaking the barrier 84 to release the composition towards the distribution container 12. Once the mixed composition has been drained into the distribution container 12, the storage container 80 is disconnected from the container. distribution container 12 and piston 28, is placed in its position (Figure 5E). The receptacle 32 of the housing 30 is then opened, typically around a hinge 100 as shown (Figure 5F), to receive the dispensing container 12. The housing 30 can then be closed and the sealing tape 86 removed to leave the dispenser 10. ready to be used. Turning now briefly to Figures 6A-6D, they show an alternative implementation of two compartments of the storage container 102. In this case, in addition to an external frangible barrier 103, two components of the hair dye are stored separately in the compartments 104 and 106, separated by a second franchable barrier 108. Preferably, an outer wall 110 of the storage container 102 is designed to be flexible. This structure is such that, when both compartments 104 and 106 are substantially full of the hair dye components, the pressure applied to the flexible outer wall 110 causes the frangible barrier 108, and typically also the barrier 103 to break (Figure 6B ). The components are then mixed by shaking (Figure 6C) and allowed to drain down to the distribution vessel (Figure 6B). The remaining steps of the distributor assembly 10 are analogous to those described with reference to Figures 5E-5G above. Finally, briefly returning to Figures 7-9, it should be appreciated that the conversion mechanism 36 described above is a preferred example selected from a large number of possible embodiments of a conversion mechanism, according to the present invention. Three additional non-limiting examples of possible conversion mechanisms are illustrated in Figures 7-9. Figure 7 shows a first alternative conversion mechanism 120 which employs a straight front drive rod link 122 between a rotating wheel 124 and a lever arm 126 acting on the piston 28. To ensure linear movement, a linear bearing 128. Figure 8 shows a second alternative conversion mechanism 130 in which the rotational input is converted to linear displacement through an adjustment bolt mechanism. Specifically, an endless gear 132 drives an internally threaded annular gear 134, which is engaged on a bolt 136. In this case, the drive mechanism is driven in reverse at the end of each use to return it to its initial position. Finally, Figure 9 shows a third alternative conversion mechanism 140, in which a single rotating lever 142 directly drives a set of bolts into a linear bearing 144. To avoid the need to run the reverse drive mechanism, provides a manual clutch arrangement 146. The clutch arrangement 146 is configured to allow decoupling of the lever 142 from the gear mechanism, so that the lever returns under the action of a spring (not shown) to its initial position. The engagement arrangement is preferably configured to allow re-engagement at 90 ° intervals, which correspond to the angle between the end and start positions of the lever 142. It should be appreciated that the foregoing descriptions are meant to serve only as examples, and that many are possible. other embodiments within the spirit and scope of the present invention. It is noted that in relation to this date, the best method known by the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following:
