FIELD OF APPLICATION
[0001] The present invention relates to a dispenser for dispensing soap powder.
Description of the prior art
[0002] The use of soap dispensers for hygiene in most of the public and non-public toilets
is well known in the prior art. These dispensers are configured to allow the dispensing
of soap in the liquid state through the presence of a pump dispensing mechanism. These
liquid soap dispensers may be of the disposable or refillable type, and may be fixed
to the wall or on a special stand. For example, wall-mounted dispensers are very common
in public places and have a base fixed to the wall, a dispensing mechanism with a
push-button or lever that can be operated to dispense the liquid soap, and a covering
body.
[0003] Less common are solid soap dispensers, inside which the entire block of soap is placed
in a special housing. Once the mechanism is activated, the block of soap comes into
contact with a soap grating element, forming flakes that are released onto the user's
hand.
Dispensers are known from documents
US 2240030 A,
US 1341174 A and
DE 29607668 U1, comprising a dispensing mechanism comprising a collecting area configured to collect
solid-state soap powder and then dispense it onto the hands of a user as a result
of a button being pressed by the user.
Problem of the prior art
[0004] Most popular soap dispensers have a dispensing mechanism designed to dispense liquid
soap. This type of soap has several limitations and disadvantages with regard to environmental
friendliness.
[0005] Because of the way they are distributed and sold, liquid soaps require the consumption
of a large amount of plastic material, which entails a higher cost for packaging the
product. In addition, the excessive use of plastic also leads to a not inconsiderable
contribution to air pollution, as a significant amount of CO
2 is required for the disposal of single-use plastic waste, the material of which the
most common disposable dispensers or refills for refillable dispensers, such as those
that can be fixed to the wall, are made.
[0006] In addition, soaps in the liquid state can be found to contain additives and preservatives
to maintain the product, which can be harmful to humans and the environment.
[0007] Still further, the storage, transport and packaging of liquid soaps require more
space, which could be reduced with other types of soap, and in particular solid soap.
[0008] Finally, in the dispensers of the above-mentioned documents, the amount of soap powder
that can be accumulated is fixed because, when the button is not pressed, the soap
itself by the effect of gravity is deposited on the collecting area. Therefore, when
the button is pressed, a predefined amount of soap powder must be dispensed, which
is sometimes excessive.
SUMMARY OF THE INVENTION
[0009] The purpose of the present invention is to present a dispenser for dispensing solid
soap, and in particular soap powder, that overcomes the drawbacks of the prior art.
In particular, it is an object of the present invention to provide a dispenser capable
of regulating the amount of soap that can be dispensed by a user.
[0010] The purpose of the present invention is to present a dispenser for dispensing solid,
soap powder as an alternative to those presented in the prior art.
Advantages of the invention
[0011] Thanks to an embodiment, it is possible to obtain a dispenser for dispensing soap
powder.
[0012] This type of soap can reduce environmental impact due to the absence or greatly reduced
consumption of single-use plastic, as soap powder packaging can be made from recycled
or biodegradable material. The soap powder can be placed in the reusable, refillable
dispenser.
[0013] Thanks to an embodiment, soap powder allows more advantageous transport and storage
as the space required for the same soap content is less than for liquid soap.
[0014] Thanks to an embodiment, soap powder, being in the solid state, comprises all-natural
or environmentally friendly ingredients, without the addition of preservatives or
other environmentally harmful chemicals, or at least with a reduced use of such potentially
harmful components.
[0015] Advantageously, thanks to the present invention, it is possible to avoid wastage
of soap powder for each individual user, thus limiting the costs of refilling the
dispenser.

DETAILED DESCRIPTION
[0017] The object of the present invention is a dispenser 1, illustrated in Figure 1, for
dispensing solid soap powder.
[0018] With reference to the accompanying figures, this dispenser 1 comprises several elements,
including a container 2 for holding soap powder, comprising a mouth 3 for dispensing
soap powder. Preferably, the container 2 is provided with an opening cap 21 to allow
the refilling of soap powder. Still preferably, the cap 21 is fitted with a gripping
tab 22 to facilitate the opening thereof.
[0019] A further element of the dispenser 1 is a dose mechanism M coupled to the mouth 3
of the container 2. The dose mechanism M comprises a platform 4 placed below the container
2, provided with a lower channel 41 for dispensing soap powder. In addition, the dose
mechanism M comprises at least one movable element 5 with respect to the platform
4 having a soap powder collecting portion 51.
[0020] The at least one movable element 5 is configured to shift with respect to the platform
4 from a position, defined as the loading position, in which the collecting portion
51 is in correspondence with the overlying mouth 3 of the container 2 for collecting
a dose of the soap powder exiting the container 2 when the dispenser 1 is in use,
to a further position, defined as the unloading position, in which the collecting
portion 51 is in correspondence with the lower channel 41 of the platform 4 for dispensing
the dose of soap powder.
[0021] Preferably, the platform 4 has an upper channel 42 connected to the mouth 3 of container
2 to receive the soap powder. It should be noted that the upper channel 42 allows
for the coupling of the dose mechanism M with the mouth 3 of the container 2. Still
preferably, the upper channel 42 has a truncated cone-shaped connecting portion to
the mouth 3, reinforced by special stiffening ribs 43. In the preferred embodiment
shown in the accompanying figures, the platform 4 has two interlocking shells, specifically
an upper shell in which the upper channel 42 is provided and a lower shell in which
the lower channel 41 is provided. The at least one movable element 5 is enclosed between
the two shells and is shiftable within the platform 4.
[0022] This dispenser 1, in particular, dispenses soap powder, instead of liquid soap as
in the prior art. The choice of soap powder has several advantages, one of which is
that it reduces the environmental impact typical of liquid soap. It should be noted
here that dispensing systems known for liquid soap are not suitable for dispensing
soap powder.
[0023] Preferably, the container 2 has a funnel or truncated cone shape to convey the soap
powder towards the mouth 3, which can be seen in Figure 2. The container 2, in addition
to the mouth 3, comprises an upper end, from which the soap powder for refilling the
dispenser 1 is inserted by means of the relevant cap 21. At the end of this operation,
for example, the cap 21 of the container 2 can be closed to preserve the integrity
of the soap powder, especially protecting it from contact with water. This can be
seen, for example, in Figures 5a and 5b.
[0024] In the preferred embodiment of the invention, the collecting portion comprises a
hole passing through the at least one movable element 5. The hole is positioned centrally
to the at least one movable element 5 and is configured for the collection of the
soap powder dose exiting the mouth 3, when the collecting portion is in the loading
position, and for the dispensing of the soap powder dose, when the collecting portion
is in the unloading position.
[0025] The loading position, not shown in the accompanying figures, is defined as the configuration
in which the hole passing through the at least one movable element 5 is at least partially
or completely aligned with the overlying mouth 3 of the container 2, thereby allowing
the collection of soap powder, which passes from the container 2 to the at least one
movable element 5 due to the effect of gravity.
[0026] The unloading position, on the other hand, is defined as the configuration in which
the hole passing through the at least one movable element 5 is completely superimposed
and aligned with the underlying lower channel 41 of the platform 4, on which the at
least one movable element 5 rests (as shown in Figure 4), thus allowing the soap powder
to be dispensed as it passes from the platform 4 to the user's hand, again due the
effect of gravity.
[0027] Still preferably, the aforementioned hole has a substantially rectangular shape,
more preferably with rounded corners, a shape that replicates the same shape as the
mouth of the lower channel 41 of platform 4, as is also shown in Figure 4.
[0028] In accordance with the present invention, the at least one movable element 5 comprises
a slider 52, substantially rectangular in shape, in which the collecting portion 51
is provided, and in particular central to the hole described above. It should be noted
that the dose of soap powder collected in the recess defined laterally to the hole
and on the bottom of the wall of the platform 4 when the slider 52 is in the loading
position, after being dragged by the slider 52 along the bottom of the platform 4
is subsequently discharged by gravity when the slider 52 moves to the unloading position
in which the hole is superimposed and aligned with the lower channel 41 of the platform
4.
[0029] In accordance with the present invention, the dose mechanism M comprises at least
one elastic element. This at least one elastic element is active on the slider 52
and is configured to be preloaded in the loading position. The above-mentioned at
least one elastic element is also configured to allow the return of the slider 52
from the loading position to the unloading position.
[0030] The at least one elastic element, in the preferred embodiment of the invention, comprises
at least one coiled spring 7, preferably a compression spring, configured to be shortened
in the loading position. Alternatively, expansion springs 7 can be used, and thus
with an opposite operating principle, i.e. they are preloaded with elongation in the
loading position. This element is most clearly visible in Figures 3a and 4. Still
preferably, two springs 7 located on opposite sides of the slider 52 are provided
(not shown in the accompanying figures). Preferably, each spring 7 arranged laterally,
is constrained at one end to the platform 4 and at the opposite end to a projecting
portion 53 of the slider 52, like a flap. This allows the at least one spring 7 not
to disengage from the slider 52 or the platform, thus preventing the elastic return
necessary to move the slider 52 from the loading position to the unloading position.
[0031] To ensure the correct trajectory of movement of the at least one spring 7, in the
preferred form of the invention, the platform 4 has at least one guide G, preferably
arranged laterally to the slider 52. Still preferably, the platform 4 comprises a
central seat 44 within which the slider 52 slides.
[0032] The aforementioned at least one guide G comprises at least one opening 45, which
allows at least in part the housing and sliding of the extension 53 of the slider
52 to determine the end stop of the loading and unloading positions of the slider
52. This mechanism is most clearly observable in Figure 4.
[0033] According to the present invention, the dose mechanism M comprises a button 6, integral
with the slider 52. The button 6 is configured to be pressable by the user to shift
the slider 52 from the unloading position to the loading position when the user wishes
to receive a dose of soap powder.
[0034] In the preferred embodiment of the invention, the button 6 is shaped like a parallelepiped
with preferably rounded corners, or shaped like a cylinder or elliptical cylinder.
[0035] With reference to the accompanying figures, it should be noted that in use, initially
in the unloading position, the collecting portion 51 is in a rest configuration in
correspondence with the lower channel 41. When the button 6 is operated, the loading
portion 51 is positioned below the upper channel 42 in the loading position, so as
to be loaded with soap powder, and under the return thrust provided by the springs
7 the collecting portion 51 returns to the unloading position in correspondence with
the lower channel 41, to release the soap powder.
[0036] Also in the preferred embodiment of the invention, the at least one elastic element,
the slider 52 and the button 6, are positioned in space in such a way that they are
arranged horizontally in series to each other (arrangement most clearly visible in
Figure 3a). Accordingly, when the user presses the button 6, the slider 52 moves horizontally,
reaching the loading position, i.e. when the hole of the slider 52 is at least partly
or completely centred on the overlying mouth 3 of the container 2. It should be noted
here that the degree of alignment and superposition of the hole of the slider 52 (or
more generally of the collecting portion 51) to the mouth 3, determines the quantity
or dose of soap powder that will be dispensed when the button 6 is released. Therefore,
the duration of pressing the button 6 affects the amount of soap powder that will
be collected and dispensed, as the principle governing the passage of soap powder
from the container 2 to the slider 52 is similar to that of an hourglass. In other
words, in the loading position the amount of soap powder deposited from container
2 to the platform 4 depends on the time for which the button 6 is pressed. In addition,
the greater the pressure, the greater the amount of soap powder in a single dose.
In fact, the linear displacement imposed by the same button 6 on the slider 52, by
means of the gradual pressure of the button 6 to the stroke end, determines an increasing
alignment between the collecting portion 51 (specifically, the hole) and the mouth
3, and therefore an increasing amount of soap powder collected in the hole of the
slider 52 per unit of time. The hole of the slider 52 is only fully aligned with the
overlying mouth 3 of the container 2 when the button 6 is fully pressed. Also in the
same position, due to the shift of the slider 52, the at least one elastic element
is preloaded. Said at least one elastic element is configured to allow the return
of the slider 52 from the loading position to the unloading position, i.e. when the
hole of the slider 5 is superimposed on the lower channel 41 of the platform 4. This
shift is made possible by the elastic return of the at least one elastic element,
following the release of the button 6 by the user.
[0037] The hole of the slider 52 is only fully superimposed with the lower channel 41 of
the platform 4 when the button 6 is fully released, at which time soap powder is dispensed
from the lower channel 41 of the platform 4 to the user's hand, due to the effect
of gravity.
[0038] Preferably, the dispenser 1 comprises a support structure 8 to support the dose mechanism
M.
[0039] Additionally, in order to facilitate the user in pressing the button 6, the dispenser
1 comprises a fixed grip element 10 arranged near the button 6, preferably fixed to
the support structure 8. Still preferably, the lower channel 41 of the platform 4
is located in an intermediate position between the button 6 and the grip element 10.
The use of this grip element 10, such as a handle in the preferred embodiment of the
invention, allows the user's fingers to grip it to facilitate pressing the button
6 with the palm of the hand. In this way, when the button 6 is released, the dose
of soap powder passes from the lower channel 41 of platform 4 directly into the palm
of the user's hand.
[0040] In the preferred embodiment of the invention, the dispenser 1 comprises a wall-fixable
base 9 comprising a vertical section, arranged to be fixed to the wall, connected
to or made as a single piece with the horizontally arranged support structure 8, below
which the grip element 10 extends. The base 9 can be fixed to a wall in a conventional
manner, e.g. by means of wall plugs or double-sided adhesive tape.
[0041] To protect the dose mechanism M for soap powder described above, the dispenser 1
comprises a body 11, which can be separated from the base 9 and optionally movable
with respect to the base 9 by means of a hinge mechanism (not shown in the accompanying
figures). Removing or opening the body 2 provides access to the dose mechanism M for
cleaning, maintenance and repair, as well as access to the container 2 for refilling
the soap powder. This body 11, preferably in the form of a hollow parallelepiped,
comprises at the front a perforated central portion through which the button 6 passes
when the body 11 is closed in relation to the base 9, as shown in Figure 1. Advantageously,
the button 6 is visible and accessible externally through the body 11 of the dispenser
1. It should be noted that the container 2 fits onto the upper channel 42 and is not
easily removable. Therefore, it is preferable to use a compressed air jet for internal
cleaning.
