Japanese Utility Model Laid-Open No. 7-22951 discloses a bag-in-bottle container, in which a hair-styling solution is supplied via a spout or a comb attached to the spout. Although it can be delivered in all directions, the hair styling liquid is not formed in the field.
[0007]
However, according to the present invention, the hair dye delivery system is
(A) a first container for holding a first material comprising hydrogen peroxide;
(B) a second container for holding the second material, and fluidly communicating the second container with the first container and adding the second material to the first material; A flowable formulation can be formed;
(C) comprises user-actuated means for mechanically generating a pressure differential to allow all of the released fluid formulation to be released from the first container in any orientation;
The first container can include a tank and an orifice in fluid communication with the tank, the orifice initially serving as an inlet for the second material and thereafter functioning as an outlet for the flowable formulation; In fact, the second material is poured into the first material and added,
The tank has an inner collapsed layer that is distinguished from the outer deformable layer of the first container, and the inner collapsed layer can be sequentially peeled from the outer deformable layer by delamination,
The inner collapsible layer consists of a flexible bag,
The orifice passes through an insertion tool fitted in the neck of the first container,
The plug has an annular channel surrounding a tubular member provided with an orifice, the annular channel being in air communication with a buffer region between the inner collapsed layer and the outer deformable layer;
(D) To prevent the first material from escapingWith plug sealA removable cap for the first container is provided, the removable cap having a female thread that is airably threaded to a male thread on the neck of the first container and forms an air passage from the annular channel to the atmosphere. .
[0008]
It will be appreciated that the present invention allows the two-component hair dye liquor to be mixed in-situ and then delivered at any time and in any orientation during the hair dyeing process.
[0009]
Preferably, the first container is at least partially transparentOrElastic deformation possibleOrBothWithMade of plastic material.
[0013]
If the tubular member extends beyond the neck of the first container and into the tank of the first container, the portion of the tubular member within the tank can take the form of a support tube secured to the plug. The tube can open in cross-section to form a channel that is at least partially rigid through which the flowable formulation can pass while the flexible bag is deflated.
[0014]
The support tubeWhile mixing the first and second materials by shaking,To restrain the flexible bag,The free end of the support tube, which is long enough to be far from the plug, is close to the free end of the flexible bag, which is far from the neck of the first container, but should not come into contact. Butpreferable.
[0015]
The insert can be fitted into the neck of the first container, and the removable cap seals the orifice in the insert until the second container is in fluid communication with the first container. Can be closed.
[0016]
Preferably, the applicator is secured to the first container to facilitate release of the flowable formulation from the first containerCan,thisThe applicator is configured to allow air to flow to a position outside the inner collapsed layer of the first container.When, Outflow of flowable formulation from a position inside the first collapsed layer of the first containerWhenThe valve member of the integral structure which can control both of these is included.
[0017]
The outlet portion of the valve member has a quadrolobe valve, the inlet portion of the valve member has a flap valve, and the flap valve has an annular shape surrounding the four-lobe valve. Has a shape.
[0018]
If the applicator is a spout having a single elongated passage that delivers a flowable formulation, the four-lobe valve can be push-fit into the elongated passage of the spout, As such, it can be push-fit directly or indirectly (via an insert) to the first container.
[0019]
Preferably, there is also provided an applicator made of foam or sponge material having an elastically compressible porous structure for delivering a flowable formulation, which is detachable press-fit to the spout. It can take the form of a pad at or near one end of the carrier.
[0020]
To make it easier to target a specific area, the pad can extend along only a portion of the outer periphery of the carrier.
[0021]
Preferably, an applicator having a plurality of elongate parting members projecting from the support is provided, the flowable formulation is fed from the housing to the support, the housing can be placed over the spout, and It can be removably fixed to the first container.
[0022]
The housing has a guide tube that receives the free end of the spout when the housing is placed over the spout.
[0023]
The elongate parting members can be flexible filaments, as in the case of a brush-type structure, but it is preferred that each of the elongate parting members take the form of fairly rigid teeth to provide a comb-like structure. .
[0024]
The teeth can be arranged in at least one row to facilitate manufacture, especially when molded from plastic materials. When viewed from the end of at least one row, the teeth may have a generally triangular profile with different lateral dimensions, but this is not necessarily so. To facilitate subsequent dispersion, the flowable formulation may be delivered from the teeth and at least one outlet may be provided at the free end of each tooth.
[0025]
The elongated parting member and the support can be removably separable from the housing. This provides a plurality of supports from which the user can select one, and the elongate parting members of the different supports are of different types. For example, instead of a comb support having fairly rigid teeth, a brush support having flexible filaments can be used.
[0026]
The elongated parting member and the support can be formed as a unit that can be secured to the housing by a securing means including a catch. The catch is elastically deflectable and can be engaged with an opening extending through the housing, and the catch can be released at a position remote from the elongated parting member. Additional catches can be provided that function as pivots. The elastically deflectable catch should be releasable by finger pressure, but simply by rolling the housing over a hard surface to release the elastically deflectable catch and support It would also be possible to remove the body from the housing.
[0027]
From the standpoint of ease of assembly and strength, the housing is screwed to be removable with respect to the first container and snaps together when the housing is fully screwed to the first container at a predetermined alignment position. Matching lug means may be formed on both the housing and the first container.
[0028]
It will be appreciated that the flowable formulation is preferably for application to the user's hair or scalp and that the first and second materials are separate components of the hair dye. It will further be appreciated that a plurality of second containers may be provided, from which one can be selected, each of the second containers containing a different color of hair dye.
[0029]
Next, according to the present invention, referring to the attached drawings as an exampleFor hair dyeThe delivery system will be described in detail.
[0030]
The accompanying drawings illustrate hair dye kits embodying all aspects of the present invention, and the various inventive aspects sought to be protected in this patent application and several contemporaneous patent applications are flowable formulations. Used when dispensing agentsHair dye delivery systemAbout.
[0031]
Fluid formulationIs a hair dye.
[0032]
There will be many problems with the use of hair dyes.
[0033]
One problem is that the hair dye must be prepared from two or more blended materials just prior to use. This means that the ingredients must be stored separately so that the user can mix the ingredients when needed. In general, one compounding material is hydrogen peroxide and another compounding material is a dye. However, the user should not be at risk of soiling when adding dye to hydrogen peroxide.
[0034]
Another problem is that the hair dye must be able to be applied to the hair with an applicator at any angle. If the applicator is fed from a simple squeeze bottle, the applicator could be used immediately in either orientation when the squeeze bottle is full. However, as the contents of the squeeze bottle gradually decrease, the applicator cannot be used immediately in either orientation, and it is necessary to first prepare the supply in order to offset the effect of the hair dye sucking back. There will be. This makes it difficult to control the application of the hair dye especially to the hairline while avoiding skin dirt.
[0035]
This hair dye kit can prepare a hair dye just before use, and it is released by the pressure difference that is generated mechanically (not aerosol), and always keeps the hair dye in either direction. It can have an applicator supplied by a user-controlled delivery system that can be released immediately.
[0036]
Omni-directional delivery is preferably possible for all of the hair dye released, which can be more than 90%, or even 95% of the prepared hair dye.
[0037]
This hair dyeing kit further contains a hair dyeing agent.User adjustable amountBy sending it to a specific area through an applicator, you can achieve a uniform color distribution with minimal dirt.
[0038]
Even with careful operation, no applicator is equally suitable for applying hair dyes to the hair root, hairline and the hair with a single applicator. Accordingly, it is common to provide different types of applicators selected from line applicators, surface applicators and brush / comb applicators. The line applicator can be a spout with a single outlet, and the surface applicator can be made of a porous material with multiple outlets. The brush / comb applicator can have a plurality of outlets for delivering the hair dye, which is then dispersed by a plurality of elongated parting members. As expected, the elongated parting member would resemble brush bristles or comb teeth. All different types of applicators can be in fluid communication with the hair dye container.
[0039]
Specific advantages of this hair dyeing kit are as follows. that is,
(A) Only one selected out of three applicators of different types is exposed during use and soiled by hair dye remaining in or on other applicators during hair treatment Eliminates the risk of
(B) Of the three applicators of different types, the surface applicator is formed of a foamed or sponge material having a porous structure that is elastically compressible in order to improve the diffusion of the hair dye.
(C) In a brush / comb applicator of three different types of applicators, at least two of the outlets are each formed in a corresponding elongated parting member to improve the dispersion of the hair dye.
[0040]
Another advantage possible with this hair dyeing kit is that the integral valve simultaneously serves the dual function of controlling the inflow of air and the outflow of hair dye, and the support of the elongated parting member is separated from the hair dye. Fixed to the housing by at least one catch that is releasable in position, with the wire applicator attached to the container, and still placing the brush / comb applicator over the wire applicator while still directly It is possible to attach to.
[0041]
A hair dye delivery system incorporating a wire applicator will be described with reference to FIGS.Surface applicator with reference to FIGS. 7 and 8 and brush / comb applicator with reference to FIGS.Do.
[0042]
The bottle 10 can be provided with a hollow body 12 having an approximately elliptical cross section,This hollow body isThe lower end is closed and an open neck 14 is provided at the upper end. An external thread 16 may be attached to the neck. In addition, a pair of opposing lug means 18 can be formed in the neck 14, only one of which is shown in FIG. Each of the lug means 18 preferably has a gap 20 to which the inclined portion 22 approaches for the purpose described below.
[0043]
At least the body 12 is made of an elastically deformable plastic material so that the bottle 10 can quickly return to its original shape when released from the squeezed state. The plastic material can be low density polyethylene, linear low density polyethylene (LLDPE) or polypropylene, and may be transparent. If not transparent, the plastic material is preferably translucent and may or may not be colored.
[0044]
A flexible bag 24 is formed by sealing two identically stacked sheets 26 along most of the common outer periphery to form a side sealed pouch having an upper opening 28 and a lower V-shaped edge 30. can do. Bag 24 is hydrogen peroxideConsist ofIt must form a tank for the first material and therefore have good water resistance. Each sheet 26 can be made of a laminated metallized material and preferably comprises three layers of LLDPE sealant / adhesive / metallized PET (polyethyl terephthalate).
[0045]
By inserting the bag 24 into the bottle 10 from the neck 14, as shown in FIG. 4, the outer deformable layer (body 12) and the inner collapsed layer (sheet 26) separated from each other in the buffer region 32. ) Can be formed.
[0046]
As shown in FIG. 4, the support tube 34 can be inserted into the bag 24 through the opening 28. The tube 34 can have a plurality of holes 36 along its length and can form a channel that is at least partially rigid open in cross-section. The lower end 38 of the tube 34 may be open or closed. The lower end portion 38 of the tube 34 may be in contact with the bag 24, but the lower end portion 38 of the tube 34 is close to the V-shaped edge 30 of the bag 24 but may not be in contact therewith. The upper end of the tube 34 can be secured to the insertion tool 40 by any suitable method or means, and can simply be press fitted onto the insertion tool 40.
[0047]
The insertion tool 40 can be partially inserted into the bag 24 from the opening 28, and can also be partially inserted into the bottle 10 from the neck 14. Preferably, the insertion tool is permanently fixed to the sheet 26 around the opening 28 by heat or ultrasonic welding. Alternatively, the insertion tool 40 and the bag 24 can be integrated. The plug 40 is preferably immovably secured to the neck 14 by a simple push-fit or other suitable method or means, but can be removed by the user to provide a refillable system. It may be.
[0048]
As shown in FIGS. 2, 4 and 6, the insert 40 includes a tubular member 42 that forms an orifice and extends to the center of the side wall 44, and a transverse wall 46 and a pair of opposed lower portions 48. And can be made into an integral plastic molded product.
[0049]
As shown, an outward flange 50 is provided at the upper end of the side wall 44 to limit the insertion of the insertion tool 40 into the bottle 10, approximately at a midpoint between the flange 50 and the transverse wall 46. Inward ribs 52 are provided. As shown, a plurality of holes 54 extend through the transverse wall 46 to couple the buffer region 32 to an annular channel 56 formed between the tubular member 42 and the side wall 44 and thus surrounding the tubular member 42. ing. The opposed lower portion 48 is illustrated as being hollow and prevents sinking of the molded article, thereby facilitating liquid tight fixing of the insert 40 to the bag 24.
[0050]
The lower end portion of the tubular member 42 is provided with an inward recess to accommodate the upper end portion of the tube 34, and the upper end portion of the tubular member 42 can be chamfered inward.
[0051]
Generally, the bag 24 is made of hydrogen peroxideConsist ofThe first material is supplied to the user in a partially filled state. Therefore, it is necessary to prevent the first material from escaping through the tube 34 and the tubular member 42. To close the upper end of the tubular member 42,A removable cap 58 is provided as shown in FIG.The
[0052]
The cap 58 can also be an integral plastic molding and can have a plug seal 60 for hermetically closing the upper end of the tubular member 42. The fixing portion 62 of the cap 58 can be fitted into the neck 14 of the bottle 10 in an airtight manner. However, there is an advantage in forming the fixing portion 62 of the cap 58 in a non-airtight manner. For example, a female thread 64 may be provided that is threadably threaded to the male thread 16 on the neck 14 of the bottle 10 to form an air passage from the annular channel 56 to the atmosphere.
[0053]
One advantage is that if the hydrogen peroxide in the bag 24 becomes unstable and generates oxygen, the bag 24 expands and the air in the buffer region 32 passes through the hole 50 in the plug 40 before the screw 16. And can escape between 64.
[0054]
Another advantage is that if the buffer area 32 is subjected to an undesired pressure change, for example due to the movement of air, air can still escape or flow into the buffer area 32 by the above path.
[0055]
The hair dye kit as described above allows the user to prepare a hair dye or other fluid preparation just prior to use.
[0056]
In practice, at least the second material is added to the first material in the tank. If the tank is supplied empty or has been emptied on a previous use, it will of course be necessary to first add some first material to the tank. In any case, it is necessary to be able to mix the materials that are initially separated.
[0057]
As schematically shown in FIG. 4, the second material can be stored in a completely independent container 66. If the first material is hydrogen peroxide, the second material appears to be a dye. If the dye reacts with oxygen, the container 66 should have excellent oxygen barrier properties. Furthermore, if the dye is in the form of a gel, cream or paste, the container 66 would have to be plastically deformable so that, for example, the user can squeeze the dye. On the other hand, if the dye is liquid, it will be able to flow out of the container 66 by the action of gravity.
[0058]
If the container 66 is elastically deformable, the bag 24 is preferably inflated with air above the first material, and if the container 66 is not elastically deformable, the bag 24 is preferably deflated. .
[0059]
A user is provided with a plurality of containers 66, each container 66 may contain a different material, such as a hair dye of a different color, and by pouring the contents of one or more of the containers 66 into a tank. In particular, special fluid preparations such as hair dyes of a selected color can be formed.
[0060]
Each of the container 66 or containers 66 preferably includes a long nozzle 68 that can extend completely through the tubular member 42 and into the tube 34. As a result, even when the user uses both hands to squeeze out the container 66, the container 66 is difficult to separate from the bottle 10, so that a good connection can be obtained. In addition, since the contents of the container 66 are jetted directly into the contents of the bag 24 from a close distance, good mixing can be promoted. Of course, before inserting the long nozzle 68 into the tubular member 42, it is necessary to open the container 66, which opens, tears off or twists the nozzle tip 70 (shown in dotted lines in FIG. 4). Can be done by taking.
[0061]
When the second material is poured from the container 66 into the bag 24, the volume of air above the first material in the bag 24 gradually decreases, preventing such compressed air escape to prevent the bag 24 from expanding. Need to promote.
[0062]
When the nozzle 68 is loosely fitted to the tubular member 42, the compressed air will escape from the loosely fitted portion. Alternatively, one or more spills are formed along the length of nozzle 68 and one or more air escape grooves are formed in the dye container near the base of nozzle 68. Either or either of them would be possible. Depending on the nature and bulk of the second material in the container 66, an air pocket that expands as the air pocket in the bag 24 contracts by injecting compressed air upward and passing the second material through. Can be formed in the container 66.
[0063]
Even when the bag 24 is inflated, the air in the buffer region 32 will escape through the holes 54 in the transverse wall 46 of the plug 40 as described above.
[0064]
After enough second material has been added to the first material, the container 66 is removed from the bottle 10 and discarded or resealed for future use.
[0065]
Instead of adding the second material to the first material by pouring, it can be formed in the bag 24, placed inside it, and destroyed by squeezing the barrel 12 of the bottle 10, etc., or otherwise The second material can be contained in a container in which the second material can be added to the first material.
[0066]
When the second materials have been added to the first material, they are preferably mixed by shaking the bottle 10 at this stage. While shaking, the user could apply a gloved finger to the upper end of the tubular member 42 to prevent the contents of the bag 24 from escaping. However, it may be more convenient for the user to refit the cap 58 so that the plug seal 60 closes the upper end of the tubular member 42. In either case, the tube 34 acts to restrain the bag 24 while the bottle 10 is shaken, reversed, or both so that the contents of the bag 24 move more freely than the bag 24. This facilitates mixing. If about 10% of the volume of the bag 24 is left as an upper space, it is considered that optimum mixing by shaking occurs. If both the bag 24 and the body 12 of the bottle 10 are translucent, it can be visually inspected whether mixing is complete.
[0067]
To prepare for the release of the flowable formulation formed by the first and second materials, and more specifically the hair dye formed by hydrogen peroxide and the dye, the plug 40 is again exposed and shown in FIG. As shown in FIGS. 5 and 6, the spout portion 72 can be attached to the insertion tool 40.
[0068]
The spout 72 is also a one-piece plastic molding, here having a cylindrical portion 74 followed by a dome-shaped portion 76 followed by a tapered portion 78. An outward rib 80 is formed at the bottom end of the cylindrical portion 74. The upper end of the cylindrical portion 74 is formed adjacent to a shoulder 82 provided by a dome-shaped portion 76. One or more, e.g., three air inlets 84 extend through the dome-shaped portion 76 and can be circumferentially spaced around the dome-shaped portion 76. An elongated passage 86 is defined in the tapered portion 78, which gradually narrows along its length from a large lower end to a smaller upper end single outlet 88. An annular recess 90 is formed on the inner surface of the tapered portion 78 near the large lower end of the passage 86. An annular rib 92 is formed on the outer surface of the tapered portion 78 near the small upper end of the passage 86.
[0069]
A valve member 94, which can be made of silicone polymer and can be a unitary structure, can be attached to the spout 72.
[0070]
The valve member 94 preferably includes an inlet portion in the form of a flapper valve 96 that functions as a one-way check valve for controlling the inflow of air from the air inlet 84.
[0071]
The valve member 94 preferably further includes an outlet portion in the form of a central quadrobe valve 98 that functions as a one-way check valve for controlling the outflow of the hair dye from the passage 86. The four-lobe valve 98 is preferred because it allows the hair dye to flow more smoothly because it opens from the center rather than the sides. However, as a modification of the four-lobe valve 98, the outlet portion of the valve member 94 may be a flap valve, an umbrella valve, or a duckbill valve.
[0072]
The flap valve 96 and the four-lobe valve 98 include a transverse seal wall 100 and a frustoconical positioning wall 102 with an annular rib 104 provided on the outer surface of the wall 102.
[0073]
The valve member 94 is easily attached to the spout 72 by pushing the four-lobe valve 98 into the passage 86 until the annular rib 104 on the valve member 94 engages the annular recess 90 in the spout 72. It is done.
[0074]
Next, the cylindrical portion of the spout portion 72 until the rib 80 of the annular portion 74 of the spout portion 72 snaps over the rib 52 of the insert 40 or snaps with at least the feel thereof. By pushing 74 into the annular channel 56 of the insert 40, the spout 72 is easily attached to the insert 40, at which time the shoulder 82 of the spout 72 abuts the flange 40 of the insert 40. The sealing wall 100 of the valve member 94 is sealingly engaged with the upper end portion of the tubular member 42 of the insertion tool 40.
[0075]
In the modified structure, the spout portion 72 can be attached to the insertion tool 40 in a screwed manner instead of the above-described push-fit manner.
[0076]
After the spout 72 is attached to the plug 40, the bottle 10 can be shaken to mix or remix the flowable formulation.
[0077]
In order to send the hair dye from the bag 24 to the outlet 88 of the spout part 72 and to release the hair dye from the bag 24 to the root of the head hair, the user squeezes the body 12 of the bottle 10. As a result, the air in the buffer region 32 is compressed, but the compressed air passes through the fluid passage including the hole 54, the annular channel 56 and the air inlet 84 because the flap valve 96 serves to close the air inlet 84. I can't escape. Instead, the compressed air partially shrinks the bag 24 so that some hair dye is open so that some hair dye can release the tube 34, the tubular member 42, the frustoconical positioning wall 102, and the hair dye. Extruded through a fluid passage containing a shaped valve 98. When the user stops the squeezing of the body 12 of the bottle 10, the bottle 10 quickly returns to its original shape, and the buffer region 32 expands. By closing the four-lobe valve 98, the hair dye is prevented from being sucked back beyond the four-lobe valve 98, and the bag 24 remains partially in its compressed state. Instead, air is drawn into the buffer region 32 through a flap valve 96 that is open to allow air to enter through the air inlet 84.
[0078]
The user repeats the squeezing of the body 12 of the bottle 10 at a pressure and frequency deemed appropriate for the situation.
[0079]
The hole 36 of the tube 34 can prevent the hair dye from being captured when the bag 24 is gradually contracted and the sheets 26 of the bag 24 come into contact with each other, and the tube 34 itself is also contracted. It will be understood that the fluid formulation within can be released.
[0080]
When delivering the hair dye, the user will be able to see that the bag 24 is deflated through at least the translucent body 12. This will reassure users who are afraid of the hair dye flowing out suddenly.
[0081]
The tank for the first material may be a side-sealed sachet as described above, but the tank may take other forms, such as an inverting-half-bag bottle or a separation It is also possible to provide an inner shrinkable layer distinguished from the outer deformable layer by means of a delaminating bottle or by a compression blown bag integrally formed with the insert. In this case, it is preferable to peel from the neck sequentially.
[0082]
Further, as described above, the valve member is a monolithic structure but can have a dual function, but the valve member can also take other forms, for example, outflow of hair dye and air. A separate valve can be provided for the control of the inflow of air, which is a simple air hole, possibly provided in the bottle body and closed with the finger by the user.
[0083]
7 and 8, the surface applicator 106 is removably secured over the outlet 88 of the spout 72. More specifically, the surface applicator 106 can include a foamed, sponge material pad 108 having an elastically compressible porous structure. Such a structure not only has a plurality of outlets, but also allows the hair dye coming out of the outlets 88 to pass through the pad 108 and be spread evenly along the hairline by careful manipulation. . The pad 108 can be disposed at or near the upper end of the carrier 110, and the lower half of the carrier 110 forms a truncated cone in the direction from the small upper end to the large lower end. An annular recess 112 is provided on the inner surface of the lower half of the carrier 110 so that the carrier 110 can be releasably engaged with the annular rib 92 on the spout 72 when the carrier 110 is pressed onto the spout 72. The carrier 110 and the spout part 72 may have a mutual structure that can prevent relative rotation. To facilitate accurate application, the pad 108 can have a curved surface that extends along only a portion of the circumference of the upper half of the carrier 110. If the pad 108 is made of a plastic material and the carrier 110 is also made of a plastic material, the pad 108 can be fixed to the carrier 110 using an adhesive. Of course, if the original surface applicator 106 is not to be cleaned and reused, a different series of surface applicators 106 may be provided that are similar for disposable use and different for replacement.
[0084]
As shown in FIGS. 9-12, instead of the surface applicator 106, a brush / comb applicator 114 can be removably secured over the outlet 88 of the spout 72 to provide a brush / comb shape. Applicator 114 includes a housing 116 and a removable unit 118.
[0085]
The brush / comb applicator 114 can be threaded or snapped onto the neck 14.
[0086]
The housing 116 is also an integral plastic molded product. When viewed from the top, the opening 120, a tapered open chamber 122 provided with a series of slotted webs 124 on the main side walls on both sides, and the chamber 128 open to the chamber 122 are communicated. The guide tube 126 to be formed, the slot 130 at the upper end portion of the chamber 128, the female screw 132 near the lower end portion of the chamber 128, and a pair of opposing lug means 134 at the lower end portion of the chamber 128 are formed.
[0087]
The internal thread 132 is preferably removable from the mold without being twisted.
[0088]
The housing 116 can be removably screwed to the bottle 10 by engaging the internal thread 132 in the chamber 128 with the external thread 16 of the neck 14. As the housing 116 is screwed sequentially, the outlet 88 of the spout 72 enters the guide tube 126. Eventually, the lug means 134 cams along the ramp 22 of the lug means 18 and snaps into the gap 20 of the lug means 18. A click or at least a feel when snapped into place indicates that the housing 116 has been fully screwed to the bottle 10. In this final position, with the lug means 18 and 132 engaged with each other, the chamber 122 opens in the direction of the major axis of the barrel 12, recalling that the barrel 12 has a substantially oval cross section.
[0089]
The removable unit 118 is the last component of the hair dyeing kit, but can also be formed as a single piece from a plastic material such as polypropylene to which silicone or the like is added to reduce the coefficient of friction.
[0090]
By making the removable unit 118 at least partially translucent, the user can be informed that the flowable formulation is about to be delivered.
[0091]
The unit 118 includes a support 136 that is substantially flat and gradually tapers from a narrow upper end to a wide lower end. An elastically deflectable catch 138 extends from the narrow upper end, and an inverted barbed tip 138a extends therefrom. A rigid catch 140 extends from a wide lower end, and an inverted barbed tip 140a extends therefrom. A skirt 142 having an outer shape corresponding to the opening of the chamber 122 is formed around the support 136. A plurality of elongated parting members, such as fairly rigid teeth 144, project from support 136 in a direction opposite to elastically deflectable catch 138, rigid catch 140 and skirt 142. A plurality of outlets 146 for the flowable formulation can be provided through the support 136.
[0092]
As best shown in FIG. 9, the teeth 144 can be arranged in two rows. When viewed from the ends of the two rows, the teeth 144 can have a generally triangular profile with different lateral dimensions, but this is not necessarily so. The lateral dimensions of the teeth 144 can gradually increase from the narrow upper end of the support 136 to the wide lower end of the support 136. In addition, the different rows of teeth 144 are staggered and also have a generally triangular profile, but at this time they can be of substantially the same thickness when viewed from the two rows of sides.
[0093]
As best shown in FIG. 11, at least two, and perhaps all, of the outlets 146 further penetrate the respective teeth 144. However, it may be desirable for one or more of the outlets 146 not to penetrate the teeth 144. For example, at least one outlet 146 can be provided in the support 136 between adjacent teeth 144. At least two, and possibly all, of the outlets 146 passing through the teeth 144 can be exposed at the orifice 148 at the free end of the teeth 144.
[0094]
In fact, it is convenient to state that the orifice 148 is at the free end of the tooth 144, one avoids directly covering the scalp, and one does not require side pins. As a result of a preferred molding technique known as a passing face shut off technique that allows the orifice 148 to be formed by a simple two-part mold, the orifice 148 is slightly displaced from the free end of the tooth 144. It is in the position retracted.
[0095]
In order to assemble the unit 118 to the housing 116, it is only necessary to fit the inverted barbed tip 140 a of the rigid catch 140 into the slot 130 and rotate it. This allows the free edge of the skirt 142 to engage the slotted web 124 and allows the inverted barbed tip 138a of the catch 138 to bend and the catch 138 fit into the opening 120. The unit 118 is fully secured to the housing 116 when the inverted barbed tip 138a of the catch 138 emerges from the opening 120 and snaps into the material of the housing 116 around the opening 120.
[0096]
To remove unit 118 from housing 116, the reverse procedure is followed. The catch 138 can be released by being pushed away by finger pressure. Alternatively, the catch 138 can be released by rolling the housing 116 over a hard surface and the hard surface pushes the inverted barbed tip 138a of the catch 138 back into the opening 120. It will be appreciated that the release of the catch 138 occurs at a location remote from the orifice 148.
[0097]
One reason for removing the unit 118 from the housing 116 would be to facilitate cleaning of residual hair dye.
[0098]
Another reason for removing the unit 118 from the housing 116 would be to allow replacement with another unit 118 of a different type. For example, a fairly rigid tooth 144 having a comb-like structure, a brush-like structure having a plurality of elastically deflectable bristles, a sponge-like structure, and teeth and orifices having different dimensions and / or shapes It may be desirable to replace it with another comb structure having both or either. This will make it easier to completely disperse the delivery hair dye in different situations such as different hair lengths or different hair types.
[0099]
The size, position and shape of the orifice 148 are changed in individual units 118 depending on the flowability of the hair dye or the need for different hair dyeing results such as root coating, streaking or highlighting. It will be.
[0100]
In general, for all of this specification, the first container to contain the first material is interpreted as including a bottle when mated with any one of the different applicators, or a combination thereof. Can do.
[0101]
As another general matter, for all of this specification, a flowable formulation is one that can demonstrate pseudoplastic flowability, which means that when subjected to shearing, the flowable formulation Once the viscosity of the agent has decreased and the shearing action has ceased, the internal structure of the flowable formulation (which can react to the original viscosity) is rebuilt very quickly to reach the internal structure of the original viscosity. Increase.
[0102]
The flowable preparation is 0.01s^-1 10000s^-1 The above-described pseudoplastic fluidity can be exhibited within the range of the shear strain rate, and such a range is the most promising shear strain rate that can be used when the fluid preparation is a hair dye. It is a range.
[0103]
An example of a flowable formulation is 2000s^-1 When measured at a shear strain rate of 0.01 Pa. s or more (preferably 0.15 Pa.s or more), 10 s^-1 When measured at a shear strain rate of 5 Pa.s. It may have a viscosity of s or less (preferably 1.4 Pa.s or less).
