Definitions
- This invention generally relates to hair care products. More particularly, the invention relates to hair dyes. Specifically, the invention relates to a hair dye dispenser that comprises two chambers that are permanently secured to each other via a valve assembly and which permit liquids stored separately in the two chambers to be mixed prior to dispensing by simply rotating one of the chambers relative to the other.
- Hair coloring systems There are a variety of hair coloring systems on the market and the product selected depends on how permanent the color change is to be.
- Hair products may be semi-permanent, demi-permanent or permanent in nature.
- Semi-permanent products contain no ammonia and coat the hair with a color. The color tends to wash out of the hair over six to twelve shampoos.
- Demi-permanent products also contain no ammonia but do contain some peroxide. Consequently, they produce more dramatic color changes than the semi-permanent products and also tend to last longer than semi-permanent products.
- the demi-permanent dyes typically last between twenty and twenty-five shampoos.
- permanent products are used to permanently change the color of the hair or may be applied to only some strands of hair to create highlights.
- Permanent products permanently change the color of that portion of the hair shaft that is contacted by the product. As such, they cannot be washed out of the hair, the color change has to be “grown out” of the hair.
- People who have used permanent products on their hair are typically concerned about their roots —, i.e., any new hair that grows after the application of the hair product will be the natural color of the person's hair. That natural hair color differs from the color of the dyed hair and the overall effect may be aesthetically displeasing.
- activities such as swimming in chlorinated pools can strip, fade and change the color of the hair. Consequently, the hair has to be dyed again every four to six weeks.
- All permanent hair dyes are created by mixing together a solution of a colorant dye that includes ammonia with a developer solution of hydrogen peroxide. Touch-up systems therefore tend to come with a bottle of ammonia-containing colorant and a separate bottle of hydrogen peroxide solution. A small open tray is provided for the mixing of these two chemical solutions. These systems are prone to user spillage and both the dye solution and the peroxide can permanently stain and damage furniture and clothing. Additionally, spilling even a small amount of either liquid will alter the end color of the dye and will therefore affect the outcome. Furthermore, the actual act of applying the dye to the hair by an untrained individual can be a messy and inexact process.
- each device at least one, and sometimes both, of the chambers must be detached from the container, opened and then reconnected in some manner to the other chamber for mixing prior to dispensing of the mixture. While this makes for neat packaging of the liquids and easier mixing of the same, it does not do away with the problems created by the potential for spillage of some of the liquid when the chambers are opened and reconnected.
- the device of the present invention comprises a two-container dispenser that is adapted to retain and separate two hair dye components until they are to be mixed immediately prior to application of the dye.
- the dispenser includes a mechanism for allowing transfer of the contents of one container into the other without having to detach either container from the dispenser.
- the dispenser further allows for mixing of the contents of the two containers and for dispensing the mixed dye from the container by simply rotating one of the containers relative to the other.
- the dispenser comprises two containers that are substantially permanently connected together via a valve assembly.
- the dispenser further includes an applicator that is secured to one of the containers and includes a dispensing hole through which the mixture is dispensed.
- the applicator further includes a plurality of bristles onto which the dispensed dye is fed.
- a cap is provided to close the dispensing hole and to cover and protect the bristles until the device is in use.
- the valve assembly is movable between a closed position and an open position by rotating one of the containers through an angle that is sufficient to open the valve assembly.
- the second container is rotated through 90 degrees in a counter-clockwise direction.
- the valve assembly is in an open position, the two components can be transferred from one container to the other.
- the dispenser can be shaken to ensure proper mixing of the components without fear of spillage or leakage from the dispenser.
- the connections between the first and second containers and the valve assembly are such that all three remain secured together when the valve assembly is moved from a closed position to an open position.

- Dispenser 10 comprises a first container 12 , a second container 14 , an applicator 16 , and a cap 18 .
- a valve assembly 20 is provided to permanently connect first and second containers 12 , 14 together.
- the first container 12 is adapted to retain a first component (not shown) of the hair dye therein.
- the second container 14 is adapted to retain a second component (not shown) of the hair dye therein.
- the first and second containers 12 , 14 , the applicator 16 and valve assembly 20 are permanently fixed together during the stages of separate storage of the first and second components of the hair dye, mixing of the first and second components; and dispensing of the mixed first and second components. At no time are any of the first and second containers 12 , 14 , the applicator 16 and valve assembly 20 detached from each other to perform any of these steps.
- First container 12 comprises a generally cylindrical body 22 that has a bottom wall 22 a , a cylindrical side wall 22 b extending outwardly away from bottom wall 22 a , and an upper end 22 c remote from bottom wall 22 a .
- Upper end 22 c is circumferentially narrower than side wall 22 b .
- Body 22 defines an interior chamber 24 that is adapted to hold the first component (not shown) of the hair dye. Typically, that first component is in liquid form. So, for example, interior chamber 24 may retain a hydrogen peroxide solution therein.
- the exterior surface of upper end 22 c is provided with first threads 26 and includes an opening 28 that provides access to interior chamber 24 .
- First threads 26 preferably are oriented in such a manner that they are counterclockwise.
- Second container 14 also comprises a generally cylindrical body 28 .
- Body 28 has a side wall 28 a that surrounds an interior chamber 30 .
- Body 28 also has an upper end 28 b and a lower end 28 c , both of which are circumferentially narrower than side wall 28 a .
- lower end 28 c is substantially the same size as upper end 22 c of first container 12 .
- Upper end 28 b of second container 14 is smaller than upper end 22 c of first container 12 and lower end 28 c of second container 14 .
- the external surface of upper end 28 b is provided with second threads 32 and has a first opening 34 therein that provides access to interior chamber 30 .
- the external surface of lower end 28 c is provided with third threads 35 .
- Second threads 35 terminate in a slightly enlarged latch 37 .
- latch 37 The purpose of latch 37 will be described later in this specification.
- Lower end 28 c includes a second opening 36 into interior chamber 30 .
- Interior chamber 30 is adapted to hold the second component (not shown) of the hair dye.
- second component is typically a liquid, such as a liquid colorant dye, but could also be a solid material.
- valve assembly 20 is disposed between and permanently connected to both of the first and second containers 12 , 14 .
- Valve assembly 20 comprises a substantially rigid valve body 38 , a flexible and resiliently compressible gasket 40 , and a rigid valve seat 42 .
- Valve body 38 and valve seat 42 preferably are manufactured from a substantially rigid plastic material.
- valve body 38 is generally tubular in shape and has an external diameter that is substantially the same as the external diameters of side walls 22 b , 28 a so that dispenser 10 appears to be a substantially continuous container.
- Valve body 38 has a central bore 44 that is sized to receive the upper end 22 c of first container 12 and the lower end 28 c of second container 14 therein.
- Valve body 38 is provided with an interior wall 39 that extends across bore 44 and substantially at a right angle to the longitudinal axis “X” ( FIG. 5 ) of dispenser 10 .
- Interior wall 39 includes an annular lip 41 that extends outwardly away therefrom and is sized to be tightly received within opening 28 when valve assembly 20 is engaged with first container 12 .
- Interior wall 39 is perforated by a D-shaped aperture 43 ( FIG. 2 a ).
- the interior surface of valve body 38 is provided with fourth and fifth threads 46 , 48 ( FIG. 4 ) that are spaced apart from each other.
- Fourth threads 46 are positioned to engage third threads 35 on lower end 28 c of second container 28 .
- Fifth threads 48 are positioned to engage first threads 26 on upper end 22 c of first container.
- Interior wall 39 is disposed intermediate fourth and fifth threads 46 , 48 .
- the interior surface of valve body 38 further includes a rotation stop mechanism 50 disposed outwardly of fourth threads 46 . Stop mechanism 50 is shown in greater detail in FIG. 7 .
- Mechanism 50 comprises two spaced-apart detents 80 , 82 which are separated from each other by a groove 84 .
- Detent 80 is shaped so as to present an inner wall 80 a that is oriented at right angles to the direction of counterclockwise rotation of valve body 38 around longitudinal axis “X”.
- Inner wall 82 a of detent 82 is slanted at an angle other than ninety degrees.
- Gasket 40 is manufactured from a flexible, deformable material and includes a D-shaped aperture 40 a therein.
- An adhesive layer (not shown) is applied to upper surface 40 of gasket 40 so that it may be secured to valve seat 42 .
- Valve seat 42 has a bottom wall 45 that is sized to be received within bore 44 of valve body 38 .
- a peripheral wall 47 extends upwardly away from bottom wall 45 a small spaced distance inwardly from the outer edge thereof. Consequently, a small lip 45 a extends annularly outwardly away from peripheral wall 47 .
- Peripheral wall 47 is positioned to extend through the second opening 36 in the lower end 28 c when valve assembly 20 is engaged with second container 14 . When peripheral wall 47 is so received, it tightly abuts the interior surface of the lower end 28 c as shown in FIG. 4 .
- Bottom wall 45 includes a D-shaped aperture 49 that is configured to be substantially identical to the D-shaped apertures 40 a and 43 in gasket 40 and valve body 38 , respectively.
- applicator 16 comprises a body that has an exterior wall 54 and an interior wall 56 that extend downwardly away from an interior surface of exterior wall 54 .
- Interior wall 56 is substantially cylindrical in shape and has an opening 57 of a diameter sized to receive upper end 28 b of second container 14 therein.
- the interior surface of interior wall 56 is provided with sixth threads 58 that are positioned to engage second threads 32 on upper end 28 b of second container 14 .
- Sixth threads 58 are oriented in a counterclockwise direction.
- Exterior wall 54 of applicator 16 has a narrower upper end 54 a and a wider, lower end 54 b .
- the diameter of lower end 54 b is substantially the same as the external diameter of side walls 22 b , 28 a of first and second containers 12 , 14 .
- the external surface of the lower end 54 b of exterior wall 54 is provided with seventh threads 64 .
- a plurality of plastic bristles 60 are secured to and extend outwardly away from upper end 54 a .
- a small dispensing hole 62 ( FIG. 6 ) is provided in upper end 54 a in the midst of bristles 60 .
- Cap 18 is designed to detachably be received over applicator 16 .
- Cap 18 comprises a body that defines a hollow interior chamber 70 .
- a tapered pin 72 extends downwardly from the interior surface of the top end 18 a of cap 18 .
- pin 72 When cap 18 is attached to dispenser 10 , pin 72 preferably is disposed substantially along the longitudinal axis “X”. Pin 72 is positioned to be received through hole 62 in upper end 54 a of applicator 16 and is sized to plug the same when so received.
- the interior surface of cap 18 is also provided with eighth threads 74 that are positioned to engage seventh threads 64 on applicator 16 .
- Valve body 38 is positioned over upper end 22 c of first container 12 so that fifth threads 48 on valve body 38 threadably engage first threads 26 on first container 12 .
- First container 12 is at least partially filled with the first liquid component (not shown) of the hair dye, such as a hydrogen peroxide solution.
- Gasket 40 is adhesively secured to the bottom wall 45 of valve seat 42 in such a manner that D-shaped apertures 40 a and 49 are aligned with each other. Valve seat 42 and gasket 40 thereby act as a single unit. Valve seat 42 and gasket 40 are then engaged with lower end 28 c of second container 14 .
- valve seat 42 is inserted into second opening 36 in lower end 28 c and because the circumference of peripheral wall 47 closely approximates the diameter of second opening 36 , valve seat 42 and gasket 40 become frictionally engaged with second container 14 . Consequently, when second container 14 is rotated, valve seat 42 and gasket 40 travel with it.
- Second container 14 is secured to valve body 38 by threadably engaging third threads 35 with fourth threads 46 .
- Third and fourth threads 35 , 46 are oriented in such a manner that when they are engaged, the first and fifth threads 26 , 48 do not disengage, but instead become further tightened.
- Second container 14 is rotated to the point that gasket 40 occludes the D-shaped aperture in valve body 38 ( FIG. 4 .), i.e., to the point that the valve assembly 20 is in the closed position.
- the interior chamber 24 of first container 12 is sealed by gasket 40 and is also simultaneously separated from the interior chamber 30 of second container 14 .
- Second container 14 is then at least partially filled, through first opening 34 , with a second dye component such as a liquid colorant dye (not shown).
- the applicator 16 is then placed over upper end 28 b of second container 14 so that upper end 28 b is received into opening 57 ( FIG. 6 ) in interior wall 56 .
- Second threads 32 on upper end 28 b are threadably engaged with sixth threads 58 on interior wall 56 .
- Cap 18 is positioned over applicator 16 so that pin 72 is received through hole 62 .
- Seventh threads 64 on applicator 16 are threadably engaged with eighth threads 74 on cap 18 .
- Pin 72 effectively seals second container 14 and prevents any the second component of the hair dye from leaking out of said second container 14 .
- a product label (not shown) preferably is then applied around the exterior surface of at least a portion of the connected first container 12 , valve assembly 20 , second container 14 , and at least a portion of cap 18 .
- the label preferably is provided with perforations and directions that indicate to the consumer where and how to rotate the relative component parts of dispenser 10 . More specifically, the label will indicate firstly how to rotate the second container 14 so as to open the valve assembly 20 and thereby permit mixing of the first and second liquid components that have been previously separated. The label will secondly indicate how to rotate cap 18 so as to remove it from over applicator 16 and to thereby open hole 62 for dispensing of mixed hair dye therethrough. Because the label rips when the components are rotated relative to each other, it therefore also provides a tamper-evident indicator for the consumer.
- the dispenser 10 is used in the following manner.
- the valve assembly 20 When purchased by the consumer, the valve assembly 20 is in the closed position shown in FIGS. 4 & 5 .
- cap 18 is engaged with applicator 16 , the pin 72 is tightly seated in hole 62 and the contents of second container 14 are retained therein.
- dispenser 10 When the consumer wishes to dye their hair, they grasp dispenser 10 and rotate the second chamber 14 through 180 degrees in a counterclockwise direction relative to valve assembly 20 and first container 12 . This is indicated by the arrow “Y” in FIG. 1 . This counterclockwise rotation through 180 degrees brings the D-shaped apertures 49 , 40 a in valve seat 42 and gasket 40 , into alignment with D-shaped aperture 43 in valve body 38 .
- FIGS. 2 & 7 show that dispenser 10 is provided with the stop mechanism 50 that ensures that there is no over-rotation of the second container 14 .
- Stop mechanism 50 also provides an indicator to the consumer that there is exact alignment of the D-shaped apertures 43 , 49 and 40 a and the valve assembly 20 is in the fully open position and first and second interior cavities 24 , 30 are in fluid communication with each other. Stop mechanism 50 functions as follows. As mentioned previously, the terminal end of the third threads 35 on the lower end 28 c of second container 28 is slightly enlarged to form a latch 37 . As second container 14 is rotated, latch 37 slides over detent 82 and into groove 84 . First and second containers 12 , 14 are blow-molded and are flexible in nature. Consequently, latch 37 is able to slide over detent 82 and into groove 84 when the second container is moved in a counter-clockwise direction.
- valve assembly 20 is therefore retained in fully open position unless a force is applied to rotate second container 14 in a clockwise direction. It should be noted that the fifth threads 48 on valve body 38 that engage first threads 26 on first container 12 are oriented so that the counter-clockwise rotation of second container 14 tightens the connection between valve body 38 and first container 12 .
- dispenser 50 grows slightly in overall length when second container 14 is rotated in a counter-clockwise direction.
- the resiliency of gasket 40 allows it to expand slightly to occupy the space between valve seat 42 and valve body 38 so that no liquids leak from dispenser 10 .
- Dispenser 10 is now in a condition where the contents of interior chambers 24 , 30 of first and second containers 12 , 14 can flow in either direction through the aligned apertures 49 , 43 and 40 a .
- the consumer then shakes dispenser 10 vigorously to mix the first and second hair dye components.
- Directions printed on the label will instruct the consumer how long to shake dispenser 10 to ensure proper mixing of the first and second components.
- the consumer grasps dispenser 10 in such a manner as to rotate cap 18 in a counter-clockwise direction. This rotation causes eighth threads 74 to disengage from seventh threads 64 , releasing the cap 18 from applicator 16 .
- pin 72 is withdrawn from hole 62 .
- the dispenser 10 may then be inverted and mixed hair dye flows out of hole 62 and onto bristles 60 . The dye may thereby be transferred onto strands of the consumer's hair as the bristles 60 are engaged therewith.
- the cap 18 may be threadably engaged with applicator 16 to seal off second container 14 and prevent any further dispensing of mixed dye therefrom.
- first and second threads 26 , 32 are oriented in a counter-clockwise direction and that rotating second container 14 and cap 18 in a counter-clockwise direction simply tightens the engagement of first container 12 with valve body 38 and applicator 16 with second container 14 . It will, however, be understood that first and second threads 26 , 32 could instead be oriented in a clockwise direction and second container 14 and cap 18 could be rotated in a clockwise relative to valve body 20 and applicator 16 respectively without departing from the spirit of the present invention, although this arrangement of components would not be conventional.
- stop mechanism 50 is provided on valve body 38 and latch 37 is provided on second container 14 ; the stop mechanism could, alternatively, be provided on the second container 14 and the latch provided on the valve body 38 without departing from the spirit of the present invention.
- Dispenser 110 comprises a first container 112 , a second container 114 , and an applicator 116 .
- a valve assembly 120 is provided to permanently connect first and second containers 112 , 114 together.
- the first container 112 is designed to retain a first component 119 ( FIG. 22 ) of the hair dye therein and the second container 114 retains a second component 121 of the hair dye therein.
- the first and second containers 112 , 114 , the applicator 116 and valve assembly 120 of dispenser 110 are permanently fixed together during the stages of separate storage of the first and second components 119 , 121 , mixing of the first and second components 119 , 121 ; and dispensing of the mixed first and second components 123 ( FIG. 23 ).
- the applicator 116 and valve assembly 120 detached from each other to perform any of these steps.
- First container 112 comprises a generally cylindrical body 122 with a bottom wall 122 a , a cylindrical side wall 122 b , and an upper end 122 c .
- Upper end 122 c is circumferentially narrower than side wall 122 b .
- Body 122 defines an interior chamber 124 that holds the first component 119 , which typically is in liquid form.
- Upper end 122 c is externally threaded with first threads 126 and includes an opening 128 that provides access to interior chamber 124 .
- First threads 126 preferably are oriented in a counterclockwise direction.
- Second container 114 comprises a generally cylindrical body 128 with a side wall 128 a that surrounds and defines an interior chamber 130 .
- Body 128 also has an upper end 128 b and a lower end 128 c , both of which are circumferentially narrower than side wall 128 a .
- Lower end 128 c is substantially the same size as upper end 122 c of first container 112 .
- Upper end 128 b of second container 114 is smaller than both of upper end 122 c of first container 112 and lower end 128 c of second container 114 .
- Upper end 128 b has exterior second threads 132 and has a first opening 134 therein providing access to interior chamber 30 .
- Lower end 128 c is externally threaded with third threads 135 .
- Third threads 135 terminate in a slightly enlarged latch 137 as in the first embodiment of dispenser 10 .
- Lower end 128 c includes a second opening 136 into interior chamber 130 .
- Interior chamber 130 holds second component 121 of the hair dye.
- second component 121 is typically a liquid, but could also be a solid material.
- valve assembly 120 is disposed between and permanently connected to each of the first and second containers 112 , 114 .
- Valve assembly 120 comprises a substantially rigid valve body 138 , a flexible and resiliently compressible gasket 140 , a rigid valve seat 142 and a member 179 .
- valve body 138 is generally tubular in shape and having an exterior wall 138 b of a diameter that is substantially the same as the external diameters of side walls 122 b , 128 a so that dispenser 110 appears to be a substantially continuous container.
- Wall 138 b defines a central bore 144 that is sized to receive the upper end 122 c of first container 112 and the lower end 128 c of second container 114 therein.
- An interior wall 139 extends across bore 144 and substantially at right angles to exterior wall 138 b and the longitudinal axis “X” ( FIG. 10 ) of dispenser 110 .

- Gasket 140 includes a reinforced central hole 159 that is shaped and sized to receive post 155 therethrough. Hole 159 is generally circular in cross-section and is designed to engage post 155 in a region where it is circular in cross-sectional shape.
- Gasket 140 further defines a pair of opposed apertures 151 that are complementary sized and shaped to align with apertures 143 in body 138 .
- a pair of opposed, slightly raised regions 161 extend upwardly from the upper surface 140 a of gasket 140 and a pair of opposed detents 163 ( FIGS.
- Detents 163 are positioned and configured to be complementary to recesses 153 in wall 139 of first container 112 .
- the engagement of detents 161 in recesses 153 seats gasket 140 in body 138 , locking the two components together so that they are able to rotate in unison.
- Detents 161 also aid in preventing gasket 140 from rotating around post 155 and relative to wall 139 .
- Valve assembly 120 further includes a valve seat 142 that secures gasket 140 against wall 139 and is rotatable between a first and second position to open and close valve assembly 120 .
- Valve seat 142 is a generally cylindrical component that has an annular outer wall 142 a that is complementary shaped and sized to be received in the bore 144 of body 138 proximate the upper end 138 a thereof.
- Valve seat 142 further includes an interior wall 142 b spaced a distance inwardly of outer wall 142 a and concentric therewith. Outer and inner walls 142 a , 142 b are separated from each other by a gap 165 ( FIG. 15 ) and the interior surface of the outer wall 142 a thereof is threaded with threads 146 .

- Valve seat 142 further includes an interior wall 145 disposed at right angles to outer and inner walls 142 a , 142 b .
- Wall 145 defines a pair of opposed apertures 167 and a central hole 169 therein.
- Hole 169 is positioned and configured to receive post 155 from body 138 therethrough.
- Hole 169 is generally cylindrical in cross-sectional shape and engages a complementary region of post 155 .
- Apertures 167 are substantially identically shaped to raised regions 161 and apertures 151 on gasket 140 .
- a butterfly-shaped member 179 is provided to assist in providing stability to valve assembly 120 and to lock valve seat 142 against gasket 140 .
- Member 179 is manufactured from a relative hard plastic and defines a central hole 173 that receives the uppermost portion of post 155 therethrough. Central hole 173 includes two flat sides ( FIG. 12 ) and is therefore complementary shaped to interlockingly engage complementary shaped uppermost portion of post 155 ( FIG. 13 ). Consequently, member 179 cannot be rotated about post 155 and member 179 and body 138 are stationary with respect to each other. Member 179 remain in a fixed orientation relative to body 138 .
- Member 179 includes a pair of wings 175 that are complementary shaped to the apertures 151 , 167 and raised regions 161 in valve assembly 120 .
- valve seat When valve seat is in the second position and therefore is in a closed condition, such as is illustrated in FIGS. 12-16 , apertures 167 are aligned with and blocked by wings 175 and raised regions 161 from gasket 140 extend upwardly through apertures 167 to contact wings 175 . A liquid tight seal is therefore maintained.
- valve seat 142 is in the first position and in an open condition such as is illustrated in FIGS. 17-21 , solid portions 171 of valve seat 142 are aligned with wings 175 .
- Apertures 167 , 151 and 143 are aligned and form a passageway through valve assembly 120 .
- applicator 116 comprises a body that has an exterior wall 154 and a pair of spaced apart annular interior walls 156 a , 156 b that extend downwardly away from an interior surface of exterior wall 154 .
- Interior wall 156 a is substantially cylindrical in shape and has an opening 157 of a diameter sized to receive upper end 128 b of second container 114 therein.
- the interior surface of interior wall 156 is provided with sixth threads 158 that are positioned to engage second threads 132 on upper end 128 b of second container 114 .
- Sixth threads 158 are oriented in a counterclockwise direction.
- Exterior wall 154 of applicator 116 has a narrower, shaped upper end 154 a ( FIG. 11 ) and a wider lower end 154 b .
- the diameter of the lower end 154 b is substantially the same as the external diameter of side wall 128 a of second container 114 .
- a plurality of plastic bristles 160 are secured to and extend outwardly away from upper end 154 a of applicator 116 .
- a small dispensing hole 162 ( FIG. 12 ) is provided in upper end 154 a in the midst of bristles 160 .
- a removable tapered pin 172 is removably received through hole 162 to close the same and prevent the contents of dispenser 10 to be accidentally dispensed through hole 162 .
- Dispenser 110 is designed so as to not require a cap to cover applicator 116 , as is the case with dispenser 10 , but it will be understood that such a cap could be provided.
- first container, second container, applicator and upper and lower ends of valve assembly in dispenser 110 preferably have the same orientations as those on the same components in dispenser 10 .
- Valve assembly 120 is pre-assembled by placing gasket 140 on wall 139 in body 138 so that post 155 is received through hole 159 , and apertures 151 in gasket 140 align with apertures 143 in body 138 .
- Valve seat 142 is placed into upper end of valve body 138 so that post 155 is received through hole 169 and gasket 140 is secured between walls 139 and 145 .
- Valve 179 is then slid onto post 155 .
- holes 159 and 169 are both circular in shape, while hole 173 in valve 179 has two flattened sides. Consequently, valve seat 142 can be rotated on post 155 , but member 179 cannot be rotated and is retained in exactly the same position at all times.
- valve seat 142 is installed on post 155 in such a closed position with regions 171 on wall 145 of valve seat 120 blocking aligned apertures 143 , 151 .
- First container 112 is at least partially filled with the first component 119 of the hair dye e.g., a hydrogen peroxide solution.
- Valve assembly 120 is screwed onto first container by threadably engaging fifth threads 148 and first threads 126 . Because valve assembly 20 is in a closed positioned, the first dye component 119 is sealed into first container 112 .
- Second container 114 is threadably engaged with valve assembly 120 by engaging third threads 135 with fourth threads 146 .
- Third and fourth threads 135 , 146 are oriented, in the same manner as in dispenser 10 , such that when they are engaged, the first and fifth threads 126 , 148 do not disengage, but instead become further tightened.
- Second dye component 121 such a colorant, is then introduced into chamber 130 of second container 114 . Because valve assembly 120 is in the closed position, second dye component 121 is retained in chamber 130 and does not flow into chamber 124 of first container 112 .
- Applicator 116 is then engaged with second container 114 by threadably engaging threads 132 with threads 158 .
- Pin 172 is inserted into hole 162 so that second dye component 121 cannot escape from chamber 130 .
- lower end 128 c of second container 114 is threadably engaged with valve seat 42 and not with body 138 of valve assembly 120 . Consequently, if second container 114 is rotated relative to first container 112 , the position of valve seat 142 relative to body 138 is changed.
- Member 179 is not connected to second container 114 but is, instead, fixed in position relative to body 138 . Body 138 , in turn, is fixedly secured to first container 112 .
- dispenser 110 may also have a tamper-evident label applied around valve-assembly 120 so that the consumer knows whether the contents of dispenser 110 have been previously mixed.
- valve seat 142 rotates in unison with second container 114 while member 179 and body 138 remain in place.
- Valve seat 142 is rotatable about post 155 between a first position and a second position that are approximately 900 apart from each other.
- apertures 167 are aligned with raised regions 161 and solid portions of wall 145 are aligned with apertures 151 and 143 . Raised regions 161 may partially extend into apertures 167 , thereby tightly sealing the same against liquid penetration.
- valve assembly 120 when valve assembly 120 is in this first position, the solid portions 171 of wall 145 block apertures 151 and there is therefore no access from second container 114 to apertures 143 in body 138 . Valve assembly 120 is therefore in a closed condition when in the first position.
- valve assembly 120 When valve assembly 120 is rotated through 90° and into the second position ( FIGS. 17-21 ), apertures 167 in wall 145 are aligned with apertures 151 in gasket 140 and, therefore, with apertures 143 in body 138 . Therefore, when valve seat 142 is in this second position, valve assembly 120 is in an open condition and the aligned apertures from a passageway through valve assembly 120 and the cavities in first and second containers 112 , 114 are in communication.
- FIG. 22 shows dispenser 110 with valve assembly 120 in a closed condition and the dye component 119 in first container 112 separated from dye component 121 in second container 114 .
- valve assembly 120 in rotated into the open condition ( FIG. 23 )
- dye component 121 from second container 114 flows into first container 112 and the consumer can shake dispenser 110 for the time indicated by directions on the label, to mix first and second dye components 119 , 121 together.
- First and second components form a mixture 123 that is retained in first container 112 .
- the consumer will remove the cap if provided.
- Pin 172 is withdrawn from hole 162 and the dispenser 110 is inverted to cause the mixture 123 to flow from first container 112 , through the passageway in valve assembly 120 , through second container 114 and out of applicator 116 through hole 162 .
- the consumer moves the bristles 160 through their hair to apply the dye mixture 123 thereto.
- pin 172 can be reintroduced into hole 162 to seal any remnants of mixture 123 within dispenser 110 .
- dispenser 110 may include a mechanism for stopping the rotation of the second container 114 relative to the valve assembly 120 .
- the stopping mechanism may comprise a stop on one of the valve assembly, more specifically valve seat 142 , and second container 114 ; and a latch on the other of the valve seat and second container.
- the stop and latch may be of the same type as disclosed in relation to dispenser 10 or be of any other suitable design.

Abstract
A two-container dispenser for storing, mixing and dispensing hair dye for touch up applications. The dispenser retains and separates two hair dye components until they are to be mixed immediately prior to application of the dye. The two containers are permanently secured together via a valve assembly. When the valve assembly is in a closed position, the interior chambers and therefore the contents of the containers remain separated. When the valve assembly is opened by rotating one of the containers through 90 degrees, the two interior chambers are placed into fluid communication with each other and the contents can flow between the containers to form a hair dye mixture. The connections between the first and second containers and the valve assembly are such that all three remain secured together when the valve assembly is moved between the closed and open positions.
Description
- This is a Continuation-in-Part of U.S. application Ser. No. 11/638,171, filed Dec. 13, 2006, the entire disclosure of which is incorporated herein by reference.
- 1. Technical Field
- This invention generally relates to hair care products. More particularly, the invention relates to hair dyes. Specifically, the invention relates to a hair dye dispenser that comprises two chambers that are permanently secured to each other via a valve assembly and which permit liquids stored separately in the two chambers to be mixed prior to dispensing by simply rotating one of the chambers relative to the other.
- 2. Background Information
- It has become commonplace for people to apply dye to their hair to completely change the color of the hair or to apply highlights thereto in order to improve their overall appearance. This alteration in the color may be done in a salon by trained professionals or by the individual in the comfort of their own home.
- There are a variety of hair coloring systems on the market and the product selected depends on how permanent the color change is to be. Hair products may be semi-permanent, demi-permanent or permanent in nature. Semi-permanent products contain no ammonia and coat the hair with a color. The color tends to wash out of the hair over six to twelve shampoos. Demi-permanent products also contain no ammonia but do contain some peroxide. Consequently, they produce more dramatic color changes than the semi-permanent products and also tend to last longer than semi-permanent products. The demi-permanent dyes typically last between twenty and twenty-five shampoos. Finally, permanent products are used to permanently change the color of the hair or may be applied to only some strands of hair to create highlights. Permanent products permanently change the color of that portion of the hair shaft that is contacted by the product. As such, they cannot be washed out of the hair, the color change has to be “grown out” of the hair. People who have used permanent products on their hair are typically concerned about their roots —, i.e., any new hair that grows after the application of the hair product will be the natural color of the person's hair. That natural hair color differs from the color of the dyed hair and the overall effect may be aesthetically displeasing. Furthermore, activities such as swimming in chlorinated pools can strip, fade and change the color of the hair. Consequently, the hair has to be dyed again every four to six weeks. However, in the interim, it may be desirable to touch up the hair color and reduce the difference between the roots and the dyed hair or to rejuvenate the color. This may be accomplished through the use of a touch-up coloring system.
- All permanent hair dyes are created by mixing together a solution of a colorant dye that includes ammonia with a developer solution of hydrogen peroxide. Touch-up systems therefore tend to come with a bottle of ammonia-containing colorant and a separate bottle of hydrogen peroxide solution. A small open tray is provided for the mixing of these two chemical solutions. These systems are prone to user spillage and both the dye solution and the peroxide can permanently stain and damage furniture and clothing. Additionally, spilling even a small amount of either liquid will alter the end color of the dye and will therefore affect the outcome. Furthermore, the actual act of applying the dye to the hair by an untrained individual can be a messy and inexact process.
- Several devices have been proposed in the prior art to address these issues. These include the devices disclosed in U.S. Pat. No. 4,823,946 issued to Stoeffler et al; U.S. Pat. No. 5,277,303 issued to Goyet et al; U.S. Pat. No. 5,647,481 issued to Hundertmark et al and U.S. Pat. No. 7,000,618 issued to Dovergne et al. All of these patents disclose containers that have two separated chambers that store liquids separately and allow them to be mixed immediately prior to application of the same. However, in each device at least one, and sometimes both, of the chambers must be detached from the container, opened and then reconnected in some manner to the other chamber for mixing prior to dispensing of the mixture. While this makes for neat packaging of the liquids and easier mixing of the same, it does not do away with the problems created by the potential for spillage of some of the liquid when the chambers are opened and reconnected.
- There is therefore a need in the art for an improved touch up dispenser for hair dye.
- The device of the present invention comprises a two-container dispenser that is adapted to retain and separate two hair dye components until they are to be mixed immediately prior to application of the dye. The dispenser includes a mechanism for allowing transfer of the contents of one container into the other without having to detach either container from the dispenser. The dispenser further allows for mixing of the contents of the two containers and for dispensing the mixed dye from the container by simply rotating one of the containers relative to the other. The dispenser comprises two containers that are substantially permanently connected together via a valve assembly. The dispenser further includes an applicator that is secured to one of the containers and includes a dispensing hole through which the mixture is dispensed. The applicator further includes a plurality of bristles onto which the dispensed dye is fed. A cap is provided to close the dispensing hole and to cover and protect the bristles until the device is in use. The valve assembly is movable between a closed position and an open position by rotating one of the containers through an angle that is sufficient to open the valve assembly. In the preferred embodiment of the invention, the second container is rotated through 90 degrees in a counter-clockwise direction. When the valve assembly is in an open position, the two components can be transferred from one container to the other. The dispenser can be shaken to ensure proper mixing of the components without fear of spillage or leakage from the dispenser. The connections between the first and second containers and the valve assembly are such that all three remain secured together when the valve assembly is moved from a closed position to an open position. Furthermore, the rotation of the containers relative to each other and to the valve assembly tears a perforated tamper evident label that is secured about the dispenser. This serves as an indicator to the consumer that the dispenser has been previously handled and that any mixed dye contained therein may have become ineffective.
- The preferred embodiments of the invention, illustrative of the best mode in which applicant has contemplated applying the principles, are set forth in the following description and are shown in the drawings and are particularly and distinctly pointed out and set forth in the appended claims.

Avalve assembly 20 is provided to permanently connect first andsecond containers first container 12 is adapted to retain a first component (not shown) of the hair dye therein. Thesecond container 14 is adapted to retain a second component (not shown) of the hair dye therein. The first andsecond containers applicator 16 andvalve assembly 20 are permanently fixed together during the stages of separate storage of the first and second components of the hair dye, mixing of the first and second components; and dispensing of the mixed first and second components. At no time are any of the first andsecond containers applicator 16 andvalve assembly 20 detached from each other to perform any of these steps. -
First container 12 comprises a generallycylindrical body 22 that has abottom wall 22 a, acylindrical side wall 22 b extending outwardly away frombottom wall 22 a, and anupper end 22 c remote frombottom wall 22 a.Upper end 22 c is circumferentially narrower thanside wall 22 b.Body 22 defines aninterior chamber 24 that is adapted to hold the first component (not shown) of the hair dye. Typically, that first component is in liquid form. So, for example,interior chamber 24 may retain a hydrogen peroxide solution therein. The exterior surface ofupper end 22 c is provided withfirst threads 26 and includes anopening 28 that provides access tointerior chamber 24.First threads 26 preferably are oriented in such a manner that they are counterclockwise. -

In the preferred embodiment of the invention,lower end 28 c is substantially the same size asupper end 22 c offirst container 12.Upper end 28 b ofsecond container 14 is smaller thanupper end 22 c offirst container 12 andlower end 28 c ofsecond container 14. The external surface ofupper end 28 b is provided withsecond threads 32 and has afirst opening 34 therein that provides access tointerior chamber 30. The external surface oflower end 28 c is provided withthird threads 35.Third threads 35 terminate in a slightlyenlarged latch 37. The purpose oflatch 37 will be described later in this specification.Lower end 28 c includes asecond opening 36 intointerior chamber 30.Interior chamber 30 is adapted to hold the second component (not shown) of the hair dye. Again, second component is typically a liquid, such as a liquid colorant dye, but could also be a solid material. - In accordance with a specific feature of the present invention,
valve assembly 20 is disposed between and permanently connected to both of the first andsecond containers Valve assembly 20 comprises a substantiallyrigid valve body 38, a flexible and resilientlycompressible gasket 40, and arigid valve seat 42.Valve body 38 andvalve seat 42 preferably are manufactured from a substantially rigid plastic material. - In accordance with a further specific feature of the present invention,
valve body 38 is generally tubular in shape and has an external diameter that is substantially the same as the external diameters ofside walls dispenser 10 appears to be a substantially continuous container.Valve body 38 has acentral bore 44 that is sized to receive theupper end 22 c offirst container 12 and thelower end 28 c ofsecond container 14 therein.Valve body 38 is provided with aninterior wall 39 that extends acrossbore 44 and substantially at a right angle to the longitudinal axis “X” (FIG. 5 ) ofdispenser 10.Interior wall 39 includes anannular lip 41 that extends outwardly away therefrom and is sized to be tightly received withinopening 28 whenvalve assembly 20 is engaged withfirst container 12.Interior wall 39 is perforated by a D-shaped aperture 43 (FIG. 2 a). The interior surface ofvalve body 38 is provided with fourth andfifth threads 46, 48 (FIG. 4 ) that are spaced apart from each other.Fourth threads 46 are positioned to engagethird threads 35 onlower end 28 c ofsecond container 28.Fifth threads 48 are positioned to engagefirst threads 26 onupper end 22 c of first container.Interior wall 39 is disposed intermediate fourth andfifth threads valve body 38 further includes arotation stop mechanism 50 disposed outwardly offourth threads 46.Stop mechanism 50 is shown in greater detail inFIG. 7 .Mechanism 50 comprises two spaced-apartdetents groove 84.Detent 80 is shaped so as to present aninner wall 80 a that is oriented at right angles to the direction of counterclockwise rotation ofvalve body 38 around longitudinal axis “X”.Inner wall 82 a ofdetent 82 is slanted at an angle other than ninety degrees. -
Gasket 40 is manufactured from a flexible, deformable material and includes a D-shapedaperture 40 a therein. An adhesive layer (not shown) is applied toupper surface 40 ofgasket 40 so that it may be secured tovalve seat 42. -
Valve seat 42 has abottom wall 45 that is sized to be received withinbore 44 ofvalve body 38. Aperipheral wall 47 extends upwardly away frombottom wall 45 a small spaced distance inwardly from the outer edge thereof. Consequently, asmall lip 45a extends annularly outwardly away fromperipheral wall 47.Peripheral wall 47 is positioned to extend through thesecond opening 36 in thelower end 28 c whenvalve assembly 20 is engaged withsecond container 14. Whenperipheral wall 47 is so received, it tightly abuts the interior surface of thelower end 28 c as shown inFIG. 4 .Bottom wall 45 includes a D-shapedaperture 49 that is configured to be substantially identical to the D-shapedapertures gasket 40 andvalve body 38, respectively. - Referring to
FIGS. 4-6 ,applicator 16 comprises a body that has anexterior wall 54 and aninterior wall 56 that extend downwardly away from an interior surface ofexterior wall 54.Interior wall 56 is substantially cylindrical in shape and has anopening 57 of a diameter sized to receiveupper end 28 b ofsecond container 14 therein. The interior surface ofinterior wall 56 is provided withsixth threads 58 that are positioned to engagesecond threads 32 onupper end 28 b ofsecond container 14.Sixth threads 58 are oriented in a counterclockwise direction. -
Exterior wall 54 ofapplicator 16 has a narrowerupper end 54 a and a wider,lower end 54 b. The diameter oflower end 54 b is substantially the same as the external diameter ofside walls second containers lower end 54 b ofexterior wall 54 is provided withseventh threads 64. A plurality of plastic bristles 60 are secured to and extend outwardly away fromupper end 54 a. A small dispensing hole 62 (FIG. 6 ) is provided inupper end 54 a in the midst ofbristles 60. -
Cap 18 is designed to detachably be received overapplicator 16.Cap 18 comprises a body that defines a hollowinterior chamber 70. A taperedpin 72 extends downwardly from the interior surface of thetop end 18 a ofcap 18. Whencap 18 is attached todispenser 10,pin 72 preferably is disposed substantially along the longitudinal axis “X”.Pin 72 is positioned to be received throughhole 62 inupper end 54 a ofapplicator 16 and is sized to plug the same when so received. The interior surface ofcap 18 is also provided witheighth threads 74 that are positioned to engageseventh threads 64 onapplicator 16. -
Dispenser 10 is assembled in the following manner.Valve body 38 is positioned overupper end 22 c offirst container 12 so thatfifth threads 48 onvalve body 38 threadably engagefirst threads 26 onfirst container 12.First container 12 is at least partially filled with the first liquid component (not shown) of the hair dye, such as a hydrogen peroxide solution.Gasket 40 is adhesively secured to thebottom wall 45 ofvalve seat 42 in such a manner that D-shapedapertures Valve seat 42 andgasket 40 thereby act as a single unit.Valve seat 42 andgasket 40 are then engaged withlower end 28 c ofsecond container 14.Peripheral wall 47 ofvalve seat 42 is inserted intosecond opening 36 inlower end 28 c and because the circumference ofperipheral wall 47 closely approximates the diameter ofsecond opening 36,valve seat 42 andgasket 40 become frictionally engaged withsecond container 14. Consequently, whensecond container 14 is rotated,valve seat 42 andgasket 40 travel with it. -
Lower end 28 c ofsecond container 14, with engagedvalve seat 42 andgasket 40, is then inserted intocentral bore 44 ofvalve body 38.Second container 14 is secured tovalve body 38 by threadably engagingthird threads 35 withfourth threads 46. Third andfourth threads fifth threads Second container 14 is rotated to the point that gasket 40 occludes the D-shaped aperture in valve body 38 (FIG. 4 .), i.e., to the point that thevalve assembly 20 is in the closed position. At this point, theinterior chamber 24 offirst container 12 is sealed bygasket 40 and is also simultaneously separated from theinterior chamber 30 ofsecond container 14.Second container 14 is then at least partially filled, throughfirst opening 34, with a second dye component such as a liquid colorant dye (not shown). - The
applicator 16 is then placed overupper end 28b ofsecond container 14 so thatupper end 28 b is received into opening 57 (FIG. 6 ) ininterior wall 56.Second threads 32 onupper end 28 b are threadably engaged withsixth threads 58 oninterior wall 56.Cap 18 is positioned overapplicator 16 so thatpin 72 is received throughhole 62.Seventh threads 64 onapplicator 16 are threadably engaged witheighth threads 74 oncap 18.Pin 72 effectively sealssecond container 14 and prevents any the second component of the hair dye from leaking out of saidsecond container 14. - A product label (not shown) preferably is then applied around the exterior surface of at least a portion of the connected
first container 12,valve assembly 20,second container 14, and at least a portion ofcap 18. The label preferably is provided with perforations and directions that indicate to the consumer where and how to rotate the relative component parts ofdispenser 10. More specifically, the label will indicate firstly how to rotate thesecond container 14 so as to open thevalve assembly 20 and thereby permit mixing of the first and second liquid components that have been previously separated. The label will secondly indicate how to rotatecap 18 so as to remove it from overapplicator 16 and to therebyopen hole 62 for dispensing of mixed hair dye therethrough. Because the label rips when the components are rotated relative to each other, it therefore also provides a tamper-evident indicator for the consumer. - The
dispenser 10 is used in the following manner. When purchased by the consumer, thevalve assembly 20 is in the closed position shown inFIGS. 4 & 5 . This means thatapertures valve seat 42 andgasket 40 are out of alignment withaperture 43 invalve body 38. Consequently,gasket 40 separatesinterior chambers cap 18 is engaged withapplicator 16, thepin 72 is tightly seated inhole 62 and the contents ofsecond container 14 are retained therein. - When the consumer wishes to dye their hair, they grasp
dispenser 10 and rotate thesecond chamber 14 through 180 degrees in a counterclockwise direction relative tovalve assembly 20 andfirst container 12. This is indicated by the arrow “Y” inFIG. 1 . This counterclockwise rotation through 180 degrees brings the D-shapedapertures valve seat 42 andgasket 40, into alignment with D-shapedaperture 43 invalve body 38.FIGS. 2 & 7 show that dispenser 10 is provided with thestop mechanism 50 that ensures that there is no over-rotation of thesecond container 14.Stop mechanism 50 also provides an indicator to the consumer that there is exact alignment of the D-shapedapertures valve assembly 20 is in the fully open position and first and secondinterior cavities Stop mechanism 50 functions as follows. As mentioned previously, the terminal end of thethird threads 35 on thelower end 28 c ofsecond container 28 is slightly enlarged to form alatch 37. Assecond container 14 is rotated, latch 37 slides overdetent 82 and intogroove 84. First andsecond containers detent 82 and intogroove 84 when the second container is moved in a counter-clockwise direction. Once ingroove 84,latch 37 abuts right angledinner wall 80 a ofdetent 80 and no further rotation of thesecond container 14 in a counter-clockwise direction is possible.Inner wall 82 a ofdetent 82 is slanted at an angle other than ninety degrees but still provides sufficient resistance to latch 37 to maintain it withingroove 84.Valve assembly 20 is therefore retained in fully open position unless a force is applied to rotatesecond container 14 in a clockwise direction. It should be noted that thefifth threads 48 onvalve body 38 that engagefirst threads 26 onfirst container 12 are oriented so that the counter-clockwise rotation ofsecond container 14 tightens the connection betweenvalve body 38 andfirst container 12. It will be understood that because of the arrangement and functioning of the various elements ofdispenser 50, thatdispenser 50 grows slightly in overall length whensecond container 14 is rotated in a counter-clockwise direction. The resiliency ofgasket 40 allows it to expand slightly to occupy the space betweenvalve seat 42 andvalve body 38 so that no liquids leak fromdispenser 10. -
Dispenser 10 is now in a condition where the contents ofinterior chambers second containers apertures dispenser 10 vigorously to mix the first and second hair dye components. Directions printed on the label will instruct the consumer how long to shakedispenser 10 to ensure proper mixing of the first and second components. Oncedispenser 10 has been shaken for the required amount of time, the consumer graspsdispenser 10 in such a manner as to rotatecap 18 in a counter-clockwise direction. This rotation causeseighth threads 74 to disengage fromseventh threads 64, releasing thecap 18 fromapplicator 16. Ascap 18 is removed fromapplicator 16,pin 72 is withdrawn fromhole 62. Thedispenser 10 may then be inverted and mixed hair dye flows out ofhole 62 and ontobristles 60. The dye may thereby be transferred onto strands of the consumer's hair as thebristles 60 are engaged therewith. - The
cap 18 may be threadably engaged withapplicator 16 to seal offsecond container 14 and prevent any further dispensing of mixed dye therefrom. - It has been disclosed, in this specification, that first and
second threads second container 14 andcap 18 in a counter-clockwise direction simply tightens the engagement offirst container 12 withvalve body 38 andapplicator 16 withsecond container 14. It will, however, be understood that first andsecond threads second container 14 andcap 18 could be rotated in a clockwise relative tovalve body 20 andapplicator 16 respectively without departing from the spirit of the present invention, although this arrangement of components would not be conventional. - It will also be understood that while
stop mechanism 50 is provided onvalve body 38 andlatch 37 is provided onsecond container 14; the stop mechanism could, alternatively, be provided on thesecond container 14 and the latch provided on thevalve body 38 without departing from the spirit of the present invention. - Referring to
FIGS. 8-23 , there is shown a second embodiment of a hair dye dispenser in accordance with the present invention and generally indicated at 110.Dispenser 110 comprises afirst container 112, asecond container 114, and anapplicator 116. Avalve assembly 120 is provided to permanently connect first andsecond containers first container 112 is designed to retain a first component 119 (FIG. 22 ) of the hair dye therein and thesecond container 114 retains asecond component 121 of the hair dye therein. As withdispenser 10, the first andsecond containers applicator 116 andvalve assembly 120 ofdispenser 110 are permanently fixed together during the stages of separate storage of the first andsecond components second components FIG. 23 ). At no time are any of the first andsecond containers applicator 116 andvalve assembly 120 detached from each other to perform any of these steps. -
First container 112 comprises a generallycylindrical body 122 with abottom wall 122 a, acylindrical side wall 122 b, and anupper end 122 c.Upper end 122 c is circumferentially narrower thanside wall 122 b.Body 122 defines aninterior chamber 124 that holds thefirst component 119, which typically is in liquid form.Upper end 122 c is externally threaded withfirst threads 126 and includes anopening 128 that provides access tointerior chamber 124.First threads 126 preferably are oriented in a counterclockwise direction. -
Second container 114 comprises a generallycylindrical body 128 with aside wall 128 a that surrounds and defines aninterior chamber 130.Body 128 also has anupper end 128 b and alower end 128 c, both of which are circumferentially narrower thanside wall 128 a.Lower end 128 c is substantially the same size asupper end 122 c offirst container 112.Upper end 128 b ofsecond container 114 is smaller than both ofupper end 122 c offirst container 112 andlower end 128 c ofsecond container 114.Upper end 128 b has exteriorsecond threads 132 and has afirst opening 134 therein providing access tointerior chamber 30.Lower end 128 c is externally threaded withthird threads 135.Third threads 135 terminate in a slightlyenlarged latch 137 as in the first embodiment ofdispenser 10.Lower end 128 c includes asecond opening 136 intointerior chamber 130.Interior chamber 130 holdssecond component 121 of the hair dye. Again,second component 121 is typically a liquid, but could also be a solid material. - Referring to
FIGS. 11-16 , and in accordance with a specific feature of the present invention,valve assembly 120 is disposed between and permanently connected to each of the first andsecond containers Valve assembly 120 comprises a substantiallyrigid valve body 138, a flexible and resilientlycompressible gasket 140, arigid valve seat 142 and amember 179. - In accordance with a further specific feature of the present invention,
valve body 138 is generally tubular in shape and having anexterior wall 138 b of a diameter that is substantially the same as the external diameters ofside walls dispenser 110 appears to be a substantially continuous container.Wall 138 b defines acentral bore 144 that is sized to receive theupper end 122 c offirst container 112 and thelower end 128 c ofsecond container 114 therein. Aninterior wall 139 extends acrossbore 144 and substantially at right angles toexterior wall 138 b and the longitudinal axis “X” (FIG. 10 ) ofdispenser 110. Anannular leg 139 a (FIG. 15 ) extends downwardly fromwall 139 and substantially parallel toexterior wall 138 b and defines agap 190 betweenleg 139 a andwall 138 b.Gap 190 is sized to receive theupper end 122 c offirst container 112 therein. The interior surface ofwall 138 bproximate gap 190 is threaded withthreads 148 configured to engagethreads 126 onfirst container 112. -
Wall 139 further defines a pair ofopposed apertures 143 and a pair ofopposed recesses 153 therein.Apertures 143 are generally triangular in shape. A longitudinally alignedpost 155 extends upwardly and outwardly from the center ofinterior wall 139.Post 155 is fixed in position and is not rotatable relative towall 139.Post 155 terminates inwardly ofuppermost end 138 a ofbody 138. The portion ofpost 155 closest to wall 139 is substantially circular in cross-section, while the uppermost end thereof has twoflat sides 155 a (FIG. 13 ), the purpose of which will be described hereinafter. As shown inFIG. 11 , the interior surface ofbody 138 extending upwardly fromwall 139 to proximate theupper end 138 a is substantially smooth and free of threads. -
Gasket 140 preferably is manufactured from a substantially planar, flexible, silicon-based material.Gasket 140 is generally circular in shape and is sized to be complementary received within thebore 144 ofbody 138.Gasket 140 includes a reinforcedcentral hole 159 that is shaped and sized to receivepost 155 therethrough.Hole 159 is generally circular in cross-section and is designed to engagepost 155 in a region where it is circular in cross-sectional shape.Gasket 140 further defines a pair ofopposed apertures 151 that are complementary sized and shaped to align withapertures 143 inbody 138. A pair of opposed, slightly raisedregions 161 extend upwardly from theupper surface 140 a ofgasket 140 and a pair of opposed detents 163 (FIGS. 9 a & 17) extend downwardly from thelower surface 140 b thereof.Detents 163 are positioned and configured to be complementary torecesses 153 inwall 139 offirst container 112. The engagement ofdetents 161 inrecesses 153 seats gasket 140 inbody 138, locking the two components together so that they are able to rotate in unison.Detents 161 also aid in preventinggasket 140 from rotating aroundpost 155 and relative towall 139. -
Valve assembly 120 further includes avalve seat 142 that securesgasket 140 againstwall 139 and is rotatable between a first and second position to open andclose valve assembly 120.Valve seat 142 is a generally cylindrical component that has an annularouter wall 142 a that is complementary shaped and sized to be received in thebore 144 ofbody 138 proximate theupper end 138 a thereof.Valve seat 142 further includes aninterior wall 142 b spaced a distance inwardly ofouter wall 142 a and concentric therewith. Outer andinner walls FIG. 15 ) and the interior surface of theouter wall 142a thereof is threaded withthreads 146.Lower end 128 c ofsecond container 114 is receivable ingap 165 andthreads 135 onend 128 c are designed to threadably engagethreads 146 onvalve seat 142. -
Valve seat 142 further includes aninterior wall 145 disposed at right angles to outer andinner walls Wall 145 defines a pair ofopposed apertures 167 and acentral hole 169 therein.Hole 169 is positioned and configured to receivepost 155 frombody 138 therethrough.Hole 169 is generally cylindrical in cross-sectional shape and engages a complementary region ofpost 155.Apertures 167 are substantially identically shaped to raisedregions 161 andapertures 151 ongasket 140. - In accordance with yet another feature of the invention, a butterfly-shaped
member 179 is provided to assist in providing stability tovalve assembly 120 and to lockvalve seat 142 againstgasket 140.Member 179 is manufactured from a relative hard plastic and defines acentral hole 173 that receives the uppermost portion ofpost 155 therethrough.Central hole 173 includes two flat sides (FIG. 12 ) and is therefore complementary shaped to interlockingly engage complementary shaped uppermost portion of post 155 (FIG. 13 ). Consequently,member 179 cannot be rotated aboutpost 155 andmember 179 andbody 138 are stationary with respect to each other.Member 179 remain in a fixed orientation relative tobody 138.Member 179 includes a pair ofwings 175 that are complementary shaped to theapertures regions 161 invalve assembly 120. When valve seat is in the second position and therefore is in a closed condition, such as is illustrated inFIGS. 12-16 ,apertures 167 are aligned with and blocked bywings 175 and raisedregions 161 fromgasket 140 extend upwardly throughapertures 167 to contactwings 175. A liquid tight seal is therefore maintained. Whenvalve seat 142 is in the first position and in an open condition such as is illustrated inFIGS. 17-21 ,solid portions 171 ofvalve seat 142 are aligned withwings 175.Apertures valve assembly 120. - Referring to
FIG. 11 ,applicator 116 comprises a body that has anexterior wall 154 and a pair of spaced apart annularinterior walls exterior wall 154.Interior wall 156 a is substantially cylindrical in shape and has anopening 157 of a diameter sized to receiveupper end 128 b ofsecond container 114 therein. The interior surface ofinterior wall 156 is provided withsixth threads 158 that are positioned to engagesecond threads 132 onupper end 128 b ofsecond container 114.Sixth threads 158 are oriented in a counterclockwise direction. -
Exterior wall 154 ofapplicator 116 has a narrower, shapedupper end 154 a (FIG. 11 ) and a widerlower end 154 b. The diameter of thelower end 154 b is substantially the same as the external diameter ofside wall 128 a ofsecond container 114. A plurality of plastic bristles 160 are secured to and extend outwardly away fromupper end 154 a ofapplicator 116. A small dispensing hole 162 (FIG. 12 ) is provided inupper end 154 a in the midst ofbristles 160. A removable taperedpin 172 is removably received throughhole 162 to close the same and prevent the contents ofdispenser 10 to be accidentally dispensed throughhole 162.Dispenser 110 is designed so as to not require a cap to coverapplicator 116, as is the case withdispenser 10, but it will be understood that such a cap could be provided. - It will be understood that the threads on first container, second container, applicator and upper and lower ends of valve assembly in
dispenser 110 preferably have the same orientations as those on the same components indispenser 10. -
Dispenser 110 is assembled in the following manner.Valve assembly 120 is pre-assembled by placinggasket 140 onwall 139 inbody 138 so thatpost 155 is received throughhole 159, andapertures 151 ingasket 140 align withapertures 143 inbody 138.Valve seat 142 is placed into upper end ofvalve body 138 so thatpost 155 is received throughhole 169 andgasket 140 is secured betweenwalls Valve 179 is then slid ontopost 155. It should be noted thatholes hole 173 invalve 179 has two flattened sides. Consequently,valve seat 142 can be rotated onpost 155, butmember 179 cannot be rotated and is retained in exactly the same position at all times. During the assembly phase,valve seat 142 is installed onpost 155 in such a closed position withregions 171 onwall 145 ofvalve seat 120 blocking alignedapertures -
First container 112 is at least partially filled with thefirst component 119 of the hair dye e.g., a hydrogen peroxide solution.Valve assembly 120 is screwed onto first container by threadably engagingfifth threads 148 andfirst threads 126. Becausevalve assembly 20 is in a closed positioned, thefirst dye component 119 is sealed intofirst container 112. -
Second container 114 is threadably engaged withvalve assembly 120 by engagingthird threads 135 withfourth threads 146. Third andfourth threads dispenser 10, such that when they are engaged, the first andfifth threads Second dye component 121, such a colorant, is then introduced intochamber 130 ofsecond container 114. Becausevalve assembly 120 is in the closed position,second dye component 121 is retained inchamber 130 and does not flow intochamber 124 offirst container 112.Applicator 116 is then engaged withsecond container 114 by threadably engagingthreads 132 withthreads 158.Pin 172 is inserted intohole 162 so thatsecond dye component 121 cannot escape fromchamber 130. - It should be noted that
lower end 128 c ofsecond container 114 is threadably engaged withvalve seat 42 and not withbody 138 ofvalve assembly 120. Consequently, ifsecond container 114 is rotated relative tofirst container 112, the position ofvalve seat 142 relative tobody 138 is changed.Member 179, on the other hand, is not connected tosecond container 114 but is, instead, fixed in position relative tobody 138.Body 138, in turn, is fixedly secured tofirst container 112. - While not shown in these figures, it will be understood that
dispenser 110 may also have a tamper-evident label applied around valve-assembly 120 so that the consumer knows whether the contents ofdispenser 110 have been previously mixed. - When the dispenser is to be used, the consumer will rotate
second container 114 about the longitudinal axis “X” thereof through an arc of 90° in a counterclockwise direction.Valve seat 142 rotates in unison withsecond container 114 whilemember 179 andbody 138 remain in place.Valve seat 142 is rotatable aboutpost 155 between a first position and a second position that are approximately 900 apart from each other. Whenvalve seat 142 is in the first position (FIGS. 12-16 ),apertures 167 are aligned with raisedregions 161 and solid portions ofwall 145 are aligned withapertures regions 161 may partially extend intoapertures 167, thereby tightly sealing the same against liquid penetration. Furthermore, whenvalve assembly 120 is in this first position, thesolid portions 171 ofwall 145block apertures 151 and there is therefore no access fromsecond container 114 toapertures 143 inbody 138.Valve assembly 120 is therefore in a closed condition when in the first position. Whenvalve assembly 120 is rotated through 90° and into the second position (FIGS. 17-21 ),apertures 167 inwall 145 are aligned withapertures 151 ingasket 140 and, therefore, withapertures 143 inbody 138. Therefore, whenvalve seat 142 is in this second position,valve assembly 120 is in an open condition and the aligned apertures from a passageway throughvalve assembly 120 and the cavities in first andsecond containers -
FIG. 22 showsdispenser 110 withvalve assembly 120 in a closed condition and thedye component 119 infirst container 112 separated fromdye component 121 insecond container 114. Whenvalve assembly 120 in rotated into the open condition (FIG. 23 ),dye component 121 fromsecond container 114 flows intofirst container 112 and the consumer can shakedispenser 110 for the time indicated by directions on the label, to mix first andsecond dye components mixture 123 that is retained infirst container 112. The consumer will remove the cap if provided.Pin 172 is withdrawn fromhole 162 and thedispenser 110 is inverted to cause themixture 123 to flow fromfirst container 112, through the passageway invalve assembly 120, throughsecond container 114 and out ofapplicator 116 throughhole 162. The consumer moves thebristles 160 through their hair to apply thedye mixture 123 thereto. When the touch-up is completed, pin 172 can be reintroduced intohole 162 to seal any remnants ofmixture 123 withindispenser 110. - It will be understood that like
dispenser 10,dispenser 110 may include a mechanism for stopping the rotation of thesecond container 114 relative to thevalve assembly 120. The stopping mechanism may comprise a stop on one of the valve assembly, more specificallyvalve seat 142, andsecond container 114; and a latch on the other of the valve seat and second container. The stop and latch may be of the same type as disclosed in relation todispenser 10 or be of any other suitable design. - In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
- Moreover, the description and illustration of the invention are an example and the invention is not limited to the exact details shown or described.
