[0001] This invention relates to a fluid applicator. The fluid applicator may be for applying
a polish to a surface.
[0002] One known fluid applicator is described in
US3384438 in which a applicator is provided in the form of a device with a handle wherein the
device has a collapsible reservoir tank with slits in a flexible wall such that external
pressure applied to the tank may cause the slits to open.
[0003] An existing method for applying polish to a floor is by using a mop. Devices are
also known by which a user carries a back pack filled with polish, which back pack
has a feed line to a mop to allow continuous supply of polish to the mop. This arrangement
is disadvantageous in that the back pack is difficult to carry and store in a domestic
setting. Also, refilling of the back pack is disadvantageously messy.
[0004] It is an object of the present invention to address the above mentioned disadvantages.
[0005] According to a first aspect of the present invention there is provided a fluid applicator
having the combined features of claim 1.
[0006] Preferably, the fluid store extends substantially across a width and/or length of
the head section. Preferably, the fluid extends over substantially the full horizontal
extent of the head section.
[0007] The head section may be triangular in plan view, preferably with rounded vertices.
[0008] The handle section is preferably joined to the head section at an upper face of the
head section, preferably substantially centrally on the upper face. The handle section
may be joined to the head section by a ball-and-socket joint, which is preferably
centrally located on the head section, preferably on an upper side thereof, a socket
of which preferably extends into the fluid store. The handle section may be joined
to the head section by a hinge, which may be formed by a flexible web.
[0009] The fluid dispensing section is preferably located in a lower face of the fluid store,
preferably substantially centrally in said lower face.
[0010] The fluid dispensing section preferably incorporates a fluid release valve biased
to a closed position, which is operable to be opened by a downward pressure on the
head section.
[0011] The fluid dispensing section is preferably operable to release fluid into an opening
in the fluid dispersal section. The opening preferably, in use, leads to a surface
on which the fluid applicator is to be used. Preferably, the opening is a substantially
central opening. The fluid dispersal section includes a pliable dispersing member,
which is preferably made of a foam material, or may be a sponge-type material. The
dispersing member may be made of an open-celled foam material, or a closed-cell foam
material, or a foam material comprising partly open cells and partly closed cells.
[0012] The dispersing member preferably surrounds the opening in the fluid dispersing section.
[0013] Preferably, the fluid store includes a filling neck, which may have a closure secured
thereto.
[0014] Preferably, the closure can either be not removable if applicator is intended to
be disposable, or removable and replaceable if applicator is intended to be refil.lable.
Preferably, the fluid applicator is a floor treatment fluid applicator, more preferably
a floor polish applicator. The fluid applicator may be a cleaning fluid applicator,
a disinfecting fluid applicator, and/or a sanitising fluid applicator.
[0015] A horizontal distance from a leading edge or vertex of the head section to a joint
with the handle section may be given by X. A vertical distance from a base of the
fluid dispersing section to an upper face of the fluid store may be given by Y. Preferably,
the ratio X:Y is greater than approximately 1.25, more preferably greater than approximately
1.35, more preferably greater than approximately 1.45.
[0016] The distance X may have a value depending on whether a stroke is a forward stroke
or a backward stroke. Thus a distance X to a front leading edge may be different to
a distance X to a rear leading edge, as in the example of a triangular head section.
[0017] The head section may include a cover section, operable to be placed over the dispersing
section. The cover section preferably includes locating tabs to assist location relative
to the dispersing member. The cover section may include a wall section adapted to
abut the opening in the dispersing section. The wall may be ring shaped. The wall
may define a cavity in the cover section, which cavity is preferably beneath the dispensing
section and may be operable to receive any drips or leaks of fluid from the fluid
dispensing section.
[0018] The head section may be triangular in shape, and may have curved, rather than angular,
vertices. The curved vertices may suitably reduce wear and tear in comparison to angular
vertices.
[0019] All of the features described herein may be combined with the above aspect.
[0020] For a better understanding of the invention, and to show how embodiments of the same
may be carried into effect, reference will now be made, by way of example, to the
accompanying diagrammatic drawings in which:

A floor polish applicator 10 comprises a body or head section 12 and a cover section
14.
The body section 12 has a triangular shape in plan view with a filling point 16 for
a reservoir 18 of the body section 12.

applicator.

and with shaped channels.

Figure 9 is a schematic cross-section viewed from above the hinge and connector component

Figure 10 is a schematic profile view viewed from above the hinge and connector component
in close-up.
[0021] A ball and socket pivot joint 20 is located centrally on an upper surface of the
body section 12. The pivot joint 20 incorporates an internally threaded sleeve 22,
in which is received a correspondingly threaded pole handle 34 (see Figure 4) of the
usual type supplied with mops etc.
[0022] The reservoir 18 communicates with a dispensing section 24 of the body section 12.
[0023] The dispensing section 24 incorporates a valve 26 through which polish or the like
held in the reservoir 18 is dispensed as described below. The valve 26 may be of a
known type which is biased by a spring to a closed position and in which application
of pressure to the valve 26 causes opening thereof.
[0024] An applicator sponge section 28 is located beneath the reservoir 18. The sponge section
28 surrounds the valve 26, with the valve 26 being in a central opening in the applicator
sponge section 28.
[0025] The applicator sponge section 28 incorporates channel sections 30a, b, c, (see Figure
3) which allow propagation of polish material from the valve 26 to edges of the applicator
sponge section 28. The channels extend from a central opening in the applicator sponge
section towards the vertices of the triangular body section 12.
[0026] Channel sections 30 a, b, c may have any profile suitable for propagation of polish
material. Figure 3 shows 3 channels of rectangular profile. In a further embodiment
it has been found that propagation of polish material is further enhanced if the channels
have a wider profile at the point nearest the central opening in the applicator sponge.
Such a profile has the added advantage of lessening the narrowing of the channels
caused by swelling of the foam distribution material on saturation with the polish
material. A particular example of this is shown in Figure 6, where the channels 30
a, b, c have a wider curved profile at the centre of the applicator device, tapering
(narrowing) to a rectangular profile at the apeces of the device.
[0027] The cover section 14 is arranged to fit over the applicator sponge section 28 and
to engage by a snap fit action with the body section 12. The cover section 14 engages
with the side walls of the reservoir 18. The cover section 14 also includes tab sections
or dividing walls 32 a/b which allow location of the cover section 14 relative to
the applicator sponge section 28 and also provide a seal from the atmosphere for the
applicator sponge section 28 to prevent drying and hardening of floor polish material
held in the applicator sponge section 28. A wall section 32a surrounds the central
opening in the applicator sponge section 28 which provides space for a valve 26. Peripheral
wall sections 32b are provided as tabs to provide means for locating the cover section
14 as mentioned above.
[0028] In a particular embodiment cover section 14 engages by snap-fit action with the body
section 12 by means of an inter-engaging mechanism located on the dividing walls 32
a/b of the cover section and inter-engages by a snap-fit with matching protrusions
on the applicator situated concentrically with the valve 26. An advantage of this
mechanism is that it retains the cover section 14 more efficiently whilst at the same
time protecting the valve opening 27 from being activated during transport or storage
of the applicator device.
[0029] The body section 12 measures approximately 220mm across each side of the triangular
shape. The reservoir 18 has a height of approximately 30mm and has a volume providing
space for approximately 500ml of polish material. The cover section has a height of
approximately 25mm. Thus, the height of the floor polish applicator 10, with the cover
removed is approximately 55mm.
[0030] Given that the floor polish applicator 10 has a generally triangular shape and given
that the pivot joint 20 is centrally located within the body section 12 of the distance
from the pivot joint 20 to the middle of one side of the body section is approximately
80mm i.e. for a forward stroke. The distance from the middle to one of the vertices,
i.e. for a backward stroke, is approximately 100mm.
[0031] The area presented by the applicator sponge section 28 to a surface to be cleaned
is approximately 250cm
2.
[0032] The floor polish applicator is provided to end users with the reservoir 18 filled
with a polish material. The filling point 16 is not removable but is permanently fixed
to the reservoir 18 after filling of the reservoir 18 during manufacture.
[0033] In use, the user would remove the cover section 14 from the floor polish applicator
10 to expose the applicator sponge section 28. A user would then place the applicator
sponge 28 on a surface to be polished by holding on to the handle section 34 as described
above. The user applies pressure to the handle and thus to the floor polish applicator
10 which pressure causes the valve 26 to contact the surface and push a valve seat
27 to an open position against a force of a spring element 29. The opening of the
valve 26 allows polish material held within the reservoir 18 to exit down on to the
surface on which the floor polish applicator 10 is located. The central opening within
the applicator sponge section 28 forms an enclosure in which the polish material is
received. The sponge section 28 typically compresses about 10mm when pressure is applied.
[0034] A user then moves the applicator 10 around the surface to be cleaned or polished.
This causes the floor polish material to be spread across the surface by the applicator
sponge section 28. The channels 30a, b, c allow the floor polish to propagate more
quickly and effectively through the sponge section 28 to achieve a good spread of
polish material. The spread of material across the sponge section 28 allows the greater
surface area of the sponge section 28 to be used to apply the polish material to the
surface.
[0035] When moving the applicator 10 across the surface it has been found that friction
can occur between the surface and the applicator 10, causing greater difficulty in
pushing the floor polish applicator 10 across the surface. It is a realisation of
the invention embodied in the floor polish applicators described herein that the friction
between the surface and the movement of the floor polish applicator creates a moment
about the leading edge or leading vertex of the applicator. When pushing the polish
applicator 10 forwards there will be a tendency of the applicator body section 12
to rotate about the leading edge or vertex. Figure 4 is a schematic diagram indicating
this tendency. In Figure 4 the leading edge of the applicator 10 is marked A. The
pivot joint 20 is marked at B. It is assumed that a handle 34 is pushed from right
to left as seen in Figure 4 there will be a tendency for the pivot joint at the point
marked B to rotate along the line marked C about point A. As mentioned above the moment
is about the point A, but results from force exerted along the handle 34.
[0036] It has been advantageously realised that by increasing the horizontal separation
between the points marked A and B in Figure 4 and/or decreasing the vertical separation
between the points marked A and B then the rolling or tipping effect discussed above
can be reduced. The effect of the horizontal separation and the vertical separation
of points A and B can be combined into the ratio of horizontal separation (X) to vertical
separation (Y) of the points A and B. A reduced rolling effect is observed as the
ratio X/Y increases. Thus, a ratio of 1 is thought to still provide a pronounced rolling/tipping
effect. However, a ratio of X over Y of 2 has advantageously reduced rolling. The
ratio in the embodiment shown in Figures 1 to 3 is approximately 2.75. Thus, a ratio
of X over Y greater than approximately 1.75 is thought to have a beneficial reduced
rolling effect.
[0037] When a vertex is forwardmost as the head section is moved along the surface the measurement
of X should be taken from the vertex to the joint. The rolling/tipping effect is also
observed on a backward stroke, in which case the measurement X would be taken as the
horizontal distance between points B and D on figure 4. In other respects the ratio
and tipping effect apply as described above.
[0038] The ball and joint socket.joint 20 may advantageously be recessed into the body section
12 to reduce the value of Y, where Y is measured from the point at which the handle
34 exerts pressure on the body section section 12 to the lower face of the sponge
section 28.
[0039] When a user has spread sufficient polish material over the surface then the cover
section 14 is replaced in order to maintain the quality of the sponge section 28,
which may otherwise dry out and harden. The hardening is typically caused by evaporation
of elements of the polish material, which evaporation is prevented or significantly
reduced by the cover section 14 having a snap fit closure with the body section 12.
[0040] Figure 5 shows a second embodiment of floor polish applicator. This embodiment has
many features in common with the first embodiment and like reference numerals have
been used for like parts.
[0041] The second embodiment differs mainly in the construction of the joint to the handle
34 and the construction of the valve 26.
[0042] The joint comprises a flattened ring-shaped base section 60 from which a cone 62
extends upwards. The cone 62 has a linear upper ridge 64 that provides a linear hinge
66 in the form of a web connected to an inverted cone 68 having a corresponding linear
ridge. The inverted cone 68 opens out to the internally threaded sleeve 22.
[0043] The hinge 66 allows flexure of the sleeve 22 and handle 34 relative to the body section
12. The relative flexure is allowed in a forwards and backwards direction, whereas
sideways flexure is deterred. This hinge 66 has the benefit of low manufacture and
production costs compared to the ball and socket joint 20 of the first embodiment.
Also, the joint has been found to be sufficiently durable to allow exhaustion of the
reservoir 18 before failing. The reservoir 18 is not intended to be refilled. Typically,
three normal-sized rooms could be treated with polish before the reservoir 18 is exhausted.
[0044] The base section 60, the sponge section 28 and the valve 26 are secured in position
with adhesive.
[0045] In the second embodiment the valve 26 has a cylindrical collar 70 that extends up
into the reservoir 18 and has at least one side opening 72. The valve seat 27 and
the spring element 29 are different to the first embodiment in that the valve seat
27 extends further downwards towards a floor to be cleaned, so that less pressure
is required on the sponge section 28 to cause actuation of the valve. The valve seat
27 is approximately 8mm long, but it will be appreciated that the length should be
matched to the thickness of the sponge section 28, so that compression thereof causes
activation of the valve seat 27.
[0046] The shape, size and material composition of the linear hinge 66 have been found to
influence the performance of the device in use, in particular with respect it its
tendency to tip and the level and ease of manoeuvrability. In a lateral direction
hinge 66 is formed at the junction of core 62 (which extends from the base section
60) and cone 68 which connects to handle 34. This is shown in detail in Figures 7
to 10. Whilst in this embodiment hinge 66 as shown is substantially linear, it may
also have a slight curvature.
[0047] The width 'a' of the hinge is preferably between 10 and 50mm, more preferably between
15 and 35 mm. In a preferred embodiment, the width is between 25 and 30 mm. In a further
embodiment, the width is between 15 and 20 mm.
[0048] The thickness 'b' of the hinge is preferably between 0.5 and 2.0 mm, more preferably
between 0.9 and 1.5 mm, especially between 1.0 and 1.4 mm. Typically this thickness
results from the thickness of the mould used to form the whole joint component 70.
It has been found that a further benefit is conferred if the component 70 is subjected
to one or more flexes immediately following forming and prior to the component fully
setting.
[0049] Component 70, and particularly hinge 66, are preferably formed from a resilient plastics
material, preferably a polyolefin, especially polypropylene. Differing grades and
types of polypropylene may be used for component 70. Three primary types of polypropylene
commonly used are
- Homopolymer (isotactic) which is made in a single reactor with propylene and catalyst.
- Random copolymer (homophasic copolymer) which is made in a single reactor with a small
amount of ethylene (<5%) added which disrupts the crystallinity of the polymer
- Impact copolymer (heterophasic copolymer) which is made in a two reactor system where
the homopolymer matrix is made in the first reactor and then transferred to the second
where ethylene and propylene are polymerized to create ethylene propylene rubber (EPR)
in the form of microscopic nodules dispersed in the homopolymer matrix phase.

[0050] The reservoir 18 in both embodiments is preferably made by a blow moulding procedure.
The reservoir 18 may be made of any suitable plastic material, such as polyethylene,
in particular high density polyethylene. The valve 26 is suitably made of any plastics
material, such as polyethylene. The handle and/or hinge may be made up of any suitable
plastics material, preferably polyethylene or polypropylene.
[0051] Floor polish formulations that may be used with the device include aqueous styrene
acrylic emulsion floor polishes, cleaning compositions, polishing compositions, liquid
coatings for gloss finishes all of which should be free-flowing liquids.
[0052] In view of the above tendency towards rolling the height of the reservoir 18 has
been minimised and its lateral extent maximised in order to provide a broad thin reservoir
that provides a beneficial X over Y ratio as defined above.
[0053] The invention has been described in relation to floor polish applicators. The invention
could equally apply to a cleaning fluid applicator, or a fluid applicator generally.
The fluid applicator could apply other protective coverings, such as a varnish or
paint.
