FIELD OF THE INVENTION
[0001] The object of the invention relates to a container to collect, mix, dissolve and
or disperse a product as well as a dispensing of its flowable content with a device
to prevent clogging of an opening of a dispensing device on the container.
BACKGROUND OF THE INVENTION
[0002] It is known that when a powder is dissolved or dispersed into a liquid clumps can
form. Undissolved powder particles and/or clumps of poorly dispersed powder particles
within the liquid can clog a dispensing device, if the opening is relatively narrow.
As controlled dispensing from an opening is desired for some applications, openings
with a small cross-section are used to prevent uncontrollable dispensing.
[0003] The problem of clump formation during a mixing process can occur not just when dissolving
and / or dispersing a powdery material into a liquid. It can also occur when dissolving
and / or dispersing granular material into a liquid, when mixing two liquids together,
or when mixing a pasty mass into a liquid. Inhomogeneities can occur with an inhomogeneous
flowable mass that is mixed with another flowable mass; these inhomogeneities can
also clog up a narrow opening, just like undissolved or poorly dispersed solid particles,
due to their high viscosity.
[0004] The problem of clump formation is especially prevalent for hair compositions which
are created by mixing a liquid together with a powder and/or granular and/or pasty
material, for example hair bleaching compositions. Such compositions typically comprise
a bleach activator in the form of a powder, granules or a pasty substance which is
mixed together with a hydrogen peroxide containing formulation. The bleach activator
will contain at least one persulfate salt, together with at least one solid buffering
agent, examples of which include but are not limited to sodium silicate or sodium
metasilicate. These primary particles typically have sizes in the order of a hundred
microns. Immediately after mixing, only a small proportion of the bleach activator
will have dissolved, whilst the majority will be dispersed within the hydrogen peroxide
formulation. The undissolved persulfate and solid buffering agents can readily agglomerate
together to form into clumps which can block the opening. The combination of large
particles, which are not readily dissolved, and the need for controlled dispensing
via use of an opening with a small cross section to prevent uncontrollable dispensing,
makes clogging of the opening a significant possibility for such hair compositions.
In addition, there is a second problem that can arise for hair bleaching compositions.
The pH of the mixed product which contains hydrogen peroxide is typically at least
8, more preferably at least 9 and even more preferably between 10 and 11. Whilst not
wishing to be bound by theory, it's believed that this elevated pH accelerates the
decomposition of hydrogen peroxide. A consequence of such an accelerated hydrogen
peroxide decomposition is that the mixed highlighting composition can evolve a significant
amount of gas over a relatively short period of time. The combination of clumps which
can clog up the narrow opening, combined with a rapid evolution of gas by the product
can lead to an increase in pressure within the container. The clog will be removed
when the pressure within the container exceeds a critical value, causing the clump
to be ejected from the narrow opening. This makes the container hazardous to handle
such hair compositions.
[0005] Publications
DE 76 39 177 and
DE 299 17054 U1 disclose a sieve-like and spring-ball-type device to hold back particles in a bottle
equipped with a pacifier for infant formula. Infant formula is created by dissolving
a fine small particle size dissolvable milk powder in warm water.
WO 98/16438 discloses a fine mesh to retain undissolved detergent composition premixed with water
prior to application onto fabrics.
[0006] These publications disclose containers for collecting a product with a dispensing
device connected to the reservoir, wherein said dispensing device has an opening to
dispense a flowable agent, particularly a powdery or granular product to be dissolved
into a liquid, with a connection between the dispensing device and the container as
well as a device to hold back excessively large particles or the undissolved product
so that the opening of the dispensing device cannot clog up, wherein the device is
fixed into position using a mount between the reservoir and the dispensing device,
and wherein the device has a multiplicity of passages, which enable the passage of
enough small particles and/or at least some of the dissolved product up to the opening.
[0007] The known containers have the disadvantage that they have passages the diameter of
which is either significantly greater or alternatively significantly smaller than
the opening to be protected, These approaches do not securely protect the opening
from clogging when used with a hair composition created by mixing together a liquid
with a powder / granular / pasty material, such as a hair bleaching composition. The
dispersed agglomerates of particles will either pass through the large passages of
the device and clog the opening, or the dispersed particles will clog the narrow passages
preventing the dispensing of product from the opening, or retain the particles on
the device, thereby altering the nature of the mixed composition dispensed from that
which is desired.
[0008] Thus, the object of the present invention is to protect the opening on containers
of the type described from clogging, in a secure manner, whilst enabling it to continue
to dispense the composition.
SUMMARY OF THE INVENTION
[0009] The object is achieved according to the characterizing portion of Claim 1. Accordingly,
the diameter or the minimum width of the passages is less than or equal to the diameter
or the minimum width of the opening.
DETAILED DESCRIPTION OF THE INVENTION
[0010] The container provided has the advantage that it offers secure protection for the
opening against clogging when used with hair compositions which are created by mixing
a liquid together with a powder / granular / pasty material, such as hair bleaching
compositions, while still enabling it to have controlled dispensing. Particles and
clumps that would be capable of blocking the opening because of their size are held
back from reaching the opening by the device, yet well mixed particles that are dispersed
within the liquid can pass through and be dispensed. If a particle or clump has a
diameter that is greater than the minimum width of a passage, it is held back at that
location. Because the device has a multiplicity of passages, it is extremely unlikely
that all of these passages could be blocked. The passages are large enough to enable
well dispersed particles to pass through and be dispensed through the opening. This
makes the container suitable to handle chemical solutions, such as those found in
hair bleaching compositions. A passage has a diameter or minimum width of between
about 0.5 mm and 5.0 mm, preferably between about 1.0 mm and 4.0 mm, more preferably
between about 1.2 mm and 3.5 mm, and even more preferably between about 2.0 and 3.0mm.
In a preferred embodiment, the device comprises a multiplicity of passages; typically
from about 3 to 150, more preferably from about 5 to 100, even more preferably from
about 10 to 75 and most preferably from about 10 to 40. Preferably, said device comprises
at least 80%, preferably at least 90%, more preferably at least 95% and most preferably
at least 99% of said multiplicity of passages having a diameter or minimum width of
from about 0.5mum to 5.0mm, preferably about 1.0mm to 4.0mm, more preferably about
1.2mm to 3.5mm. In a particularly preferred embodiment said device comprises from
10 to 40 passages wherein 99% have a diameter or minimum width of from about 1.2mm
to 3.5mm. The passages may be of an identical or non identical shape and size. Preferably,
the passages have a substantially regular shape and more preferably are substantially
circular and or oblong/slot shaped. In a particularly, preferred embodiment the device
comprises two types of passages circular and slot shaped. The passages may also be
distributed in a random manner or in a pattern. Preferably the slot shaped passages,
if present, are distributed around the perimeter edge of the device. In another embodiment
the slot shaped passages are distributed around the perimeter edge of the device and
the circular passages are distributed within the centre area of the device formed
by the slot shaped passages. The device may also comprise a part which is passage
free, this part is preferably located in substantially the centre of the device. The
device itself may also have any shape, but is preferably substantially flat or has
an upright or inverted arch shape. The depth of the device is preferably constant
and is preferably from about 0.1mm to 10mm, more preferably from about 0.5mm to 5.0mm,
most preferably from about 0.5 to 2mm. Advantageous embodiments of the proposed container
are described in Claims 2 through 10.
[0011] A spout (Claim 2), which can be attached or screwed onto the container, is suitable
as the dispensing device; this spout can be used to apply a cosmetic agent for hair
to a precise location. In particular, a colorant can be applied to the hairline. Alternatively,
a hair composition can be precisely loaded into an applicator, which is then subsequently
used to apply the composition to the hair, or selection of hair strands.
[0012] The device functions effectively and provides the maximum possible room in the container
for the product to be dissolved / dispersed, along with the liquid in which the product
is to be dissolved / dispersed, for the purpose of agitating the liquid to support
the dissolving / dispersion processes if, similarly to Claim 3, the device is mounted
at a connection point between the container and the mounting ring of the dispensing
device.
[0013] If, according to Claim 4, there is a circumferential edge of the device clamped in
between the mounting ring on the dispensing device and the upper end of a container
neck, the device can be easily inserted into the container by placing it on the front
of the container and then fixing it into position through placement of the dispensing
device.
[0014] The container reservoir is suitable, in an advantageous manner, for collecting a
product to color or bleach hair. In doing so, the product can be provided in the container
in the form of a powder, a granular material, or a pasty mass to be dissolved / dispersed
therein in a liquid, especially a hydrogen peroxide solution.
[0015] A particular advantage is achieved if, according to Claim 5, a centre part of the
device, which is preferably circular , is free of any passage. The closed center part
then protects the opening from the powder, granular material or cream to be dissolved
/ dispersed in a liquid during the shaking of the container to facilitate mixing.
Whilst not wishing to be bound by theory, it is believed having a closed centre part
can prevent the powder / granular / pasty material from becoming lodged within the
opening during the shaking process. With a round container neck, a rotationally symmetrical
dispensing device, or a round device to hold back particles, a closed center part
on the device enables the protection of the opening in a secure manner.
[0016] To increase the passage surface and thus achieve less outflow resistance after the
components have been mixed, it is advantageous, in a known manner, it a recess is
provided in the device (Claim 6). For space considerations, it is helpful to extend
this recess up to the reservoir, as is known from the prior art. To keep the recess
from extending too far into the reservoir, it is advantageous if, according to Claim
7, the recess forms a platform that is connected to the edge of the device via a circumferential
flank and an annular connection area. Based on the results obtained in experiments,
it is helpful, depending on the case, if round passages with a certain diameter as
well as slot-shaped passages with a certain length and width are recessed in the device
(Claim 8). If only slot-shaped passages are provided in the flank (Claim 9), smaller
particles that move somewhat parallel with respect to the flank can better pass through
the passages.

to the invention,
[0019] A reservoir 2 is used to collect a product 3 in a container 1 (Fig. 1, Fig. 2). A
dispensing device 4 connected to the reservoir 2 has an opening 5 to dispense a flowable
agent, particularly a powdery or granular product 3 to be dissolved / dispersed in
a liquid 8. A connection 6 between the dispensing device 4 and the container 1 is
designed as a plug connection with a snap-on cam 15. The dispensing device 4 is a
spout 14 that can be attached to the container 1.
[0020] A plate-type device 7 inserted into the dispensing device 4 is used to hold back
excessively large particles and / or clumps so that they cannot reach the opening
5 of the dispensing device 4 and cause the opening 5 to become clogged yet enables
well dispersed particles to pass through (Figs. 3 through 6). The device 7 is fixed
into position using a mount 9 between the reservoir 2 and the dispensing device 4
and has a multiplicity of passages 10, which enable the passage of clump free mixed
product 3 up to the opening 5. The multiplicity of passages are from about 3 to about
150 passages, more preferably from about 5 to about 100 passages and even more preferably
from about 10 to about 75 passages. The device 7 can be mounted to the dispensing
device 4 in the area of a connection 6 between the container 1 and a mounting ring
16. In the exemplary embodiment from Figs. 3 and 4, the device 7 is attached to the
mounting ring 16 at an edge-side connection area 23. In the exemplary embodiment from
Figs. 5 and 6, the device 7 is placed on a container neck 18 designed specifically
for this purpose before the dispensing device 4 is screwed onto the container 1 using
a threaded connection 25. Once the dispensing device 4 is screwed into place, the
circumferential connection area 23 of the device 7 is clamped between the mounting
ring 16 and the upper end 17 of the container neck 18.
[0021] With the exemplary embodiment from Fig. 7, the edge-side connection area 23 of a
round device 7 is clamped in the area of a mount 9 of the dispensing device 4. Common
among all of the exemplary embodiments is that the diameter 11 or the minimum width
12 of the passages 10 is less than or equal to the diameter 13 or the minimum width
of the opening 5 (Figs. 8 through 19) in order to securely protect the opening 5 of
the dispensing device 4 designed as a spout 14 from excessively large particles and
/ or clumps of a product 3 to be dissolved / dispersed in a liquid 8, yet enable the
well dispersed particles to pass through the opening (Fig. 7). With the exemplary
embodiment from Fig. 7, the reservoir 2 contains a peroxide solution as the liquid
8, in which a granular-type product 3, which is part of a persulfate bleaching composition,
is added to be dispersed into the liquid 2. Shortly after the product 3 is added,
a portion of the product 3 is better dispersed than the rest of the product 3. The
areas which are poorly dispersed and which form clumps, which could clog the opening
5, cannot pass through the passages 10. These clumps cannot therefore clog up the
opening 5. If a clump of the powder remains poorly dispersed after the mixing of a
powdery product and if the solution is supposed to be dispensed through the opening
5, the liquid 8 along with well dispersed product 3 could pass through the device
7 and the opening 5 and only the large particles together with these clumps would
be held back at the device 7 in order, thereby preventing the clogging of the opening
5.
[0022] If the center part 19 of the device 7 is designed without a passage 10 (Figs. 8 through
11 and 14 through 19), a particle located in the center of the reservoir 2 is less
likely to become lodged in the opening 5 during shaking. Whilst not wishing to be
bound by theory, it believed that the act of shaking can lead to the powder particulates
becoming compacted within the inside of the spout 14, forming a block which can then
prevent dispensing through the opening. The device 7 designed without a passage 10
in the centre part 19, reduces the chance of the powder particulates becoming compacted
within the inside of the spout 14. A recess 20 in the device 7 enlarges the surface
area of the device 7 and enables a larger number of passages 10 to be present on the
device 7 and hence a better dispensing of the liquid 8 from the spout 14.
[0023] Contrary to a flat design of the device 7 (Figs. 3, 5, 7,12, and 13), a device 7
may be designed as an arch and form a platform (21) that is connected to the edge
of the device 7 via a circumferential flank 22 and an annular connection area 23 (Figs.
8 to 11 and 16 through 19) or it can form a dome in the center (Figs. 14 and 15).
Such arch or dome designs may be oriented such that they extend upwards towards the
opening 5 or more preferably down towards the reservoir 2. Round passages 10 with
a certain diameter 11 as well as slot-shaped passages 10 with a certain length 24
and width 12 can be recessed in the device 7. With some of the exemplary embodiments
(Figs. 9, 10, 11, and 16 through 19), only slot-shaped passages 10 are provided in
one flank 22 to achieve lower flow resistance of the device 7 for improved dispensing
of the liquid 8. In general, a slot-shaped passage 10 is advantageous in that it only
allows small particles to pass through and still offers a large passage area for the
liquid 8 to be dispensed.
[0024] According to a further aspect of the present invention, for the purpose of sale and/or
use, a kit (26) for creating hair bundle effects may be assembled in a package, preferably
a box (31) as shown in Fig. 20. In one embodiment as shown in Fig. 20, the kit (26)
comprises the container (1) as disclosed herein and at least one product (3). Preferably

composition is selected from the group consisting of highlighting compositions, dyeing
compositions, perming compositions, styling compositions and combinations thereof.
Even more preferably, the hair treatment composition is selected from the group consisting
of highlighting compositions, dyeing compositions and combinations thereof, yet even
more preferably the hair treatment composition is a highlighting composition. The
highlighting composition is prepared by mixing a first component and a second component.
The first component is preferably comprised within the container (1) whereas the second
component is separately packed. The second component is then added to the first component
to form a hair treatment composition. The first component preferably comprises from
about 3% to about 12% of hydrogen peroxide by weight of the first component. The second
component is preferably in the form of a powder, granules or paste and comprises from
about 10% to about 60% of persulfate salt selected from the group consisting of sodium
persulfate, potassium persulfate, ammonium persulfate and mixtures thereof by weight
of the second component. The kit (26) optionally comprises a third component comprising
from about 3% to about 25% of an alkalizing agent in an aqueous vehicle, by weight
of the third component.
[0025] In another embodiment of the present invention, the hair treatment composition is
prepared by mixing a first component comprising from about 1.5% to about 12% of hydrogen
peroxide by weight of the first component and a second component comprising from about
0.01% to about 6% of a dye selected from the group consisting of direct dyes, oxidative
dye precursors, oxidative dye couplers and mixtures thereof, by weight of the second
component.
[0026] The hair treatment compositions may further comprise components known, conventionally
used, or otherwise effective for use in hair treatment compositions particularly oxidative
bleaching and dye compositions which include but are not limited to: developer dye
compounds; coupler dye compounds; direct dyes; oxidizing agents; reducing agents;
thickeners; chelants; pH modifiers and buffering agents; alkalising agents, carbonate

or non-volatile, modified or non-modified), film-forming agents, cellulose polymers
and their derivatives, ceramides, preserving agents, gel network, colour indicators
and opacifiers. Some adjuvants which are suitable are listed in the International
Cosmetics Ingredient Dictionary and Handbook, (8th ed.; The Cosmetics, Toiletry, and
Fragrance Association). Particularly, vol. 2, sections 3 (Chemical Classes) and 4
(Functions) and are useful in identifying specific adjuvants to achieve a particular
purpose or multipurpose. A representative but not exhaustive list of polymers and
thickening agents can be found in "
The Encyclopaedia of Polymers and Thickeners for Cosmetics" compiled and edited by
Robert Y. Lochhead, PhD and William R. Fron, Department of Polymer Science, University
of Southern Mississippi.
[0027] The kit (26) may further comprise an applicator (27) for applying the hair treatment
composition to the hair. The applicator (27) is selected from the group consisting
of comb applicators, brush applicators, wand-like applicators, two-parts movably joined
applicators and combinations thereof. Preferably the applicator is a two-part movably
joined applicator as shown in Fig. 20.
[0028] The kit (26) may also comprise one or more marking tools (28; 29) for marking and
separating a hair bundle from the remaining hair. Many types of marking tools (28;
29) can be used, including clips, such as those conventionally used for hair care.
Preferably the marking tools (28; 29) are substantially flat as shown in Fig. 20.
[0029] In another embodiment, the kit (26) further comprises an implement (30), wherein
the implement (30) comprises a plurality of marking tools (28; 29) for marking and
separating a hair bundle from the remaining hair. Preferably, each marking tool of
