[0001] The present invention refers to an improved hygienic device for sanitary fixtures.
[0002] The use of hygienic devices for sanitary fixtures, such as for example a WC, to be
hung in the sanitary fixture through a suitable hook which is engaged on the perimeter
edge of the same is known. The known hygienic devices can be divided into the so-called
"solid toilet bowl cleaners", comprising a detergent and/or deodorant means for toilet
in the solid state or in form of gel, and the so-called "liquid toilet bowl cleaners",
comprising a detergent and/or deodorant means for toilet in the liquid state dispensed
through a bottle.
[0003] In particular, the first type of known hygienic devices for toilets usually comprises
a perforated dispenser, referred to as "cage", provided with a hook for engaging with
the edge of the toilet bowl and containing the detergent and/or deodorant means therein
in form of a solid block, usually referred to as "soap bar". Generally the detergent
and/or deodorant means in the solid state is manufactured through an extrusion process.
Every time the toilet water is flushed, the water that directly impacts the cage dispenser
element it dissolves and washes out a small amount of the detergent and/or deodorant
product from the solid block contained in the cage.
[0004] A drawback of such cage devices lies in the high environmental impact of the same.
Actually, upon terminating their use, when the detergent and/or perfuming means are
consumed, the entire dispenser element, comprising the hook and the cage, is discarded
without the possibility of reutilisation. In addition, the cage devices, when applied
in the toilet, are cumbersome and with an aesthetic appeal that can be deemed as unappealing.
[0005] Even other toilet hygienic devices were developed having the solid detergent and/or
perfuming means hung on the perimeter edge using a structure less cumbersome than
the cage. For example, document
WO 2007/107750 A1 illustrates a solid detergent means substantially having the entire outer surface
exposed to the flushed water. The plate-shaped end of the hook for hanging to the
perimeter edge of the toilet is directly submerged in the solid detergent means. According
to the the teaching of document
WO 2007/107750 A1, the plate is inserted into a groove made in the solid detergent block which is enclosed
around it through a compression step.
[0006] Even document
EP 1891197 A1 describes a process for the production of a solid detergent block adapted to be hung
on the edge of a toilet. A part of the hook for hanging to the perimeter edge of the
toilet is inserted into the solid block and such solid block is subjected to compression
for encapsulating the part of the hook.
[0007] Another example of a toilet hygienic device comprising a solid detergent and/or perfuming
means is illustrated in document
WO 2011/141720 A1, which teaches the fitting of a solid detergent block on a plate arranged either
at the front or at the rear with respect to the wall of the WC. Even in this type
of devices the dimension of the structure is smaller than the devices of the cage
type, but it still has an external structure for supporting the solid block. In addition,
such support structure remains visible during use, especially if it is of the front
type, and it negatively affects the circulation of the flushed water around the solid
block and, thus, the uniformity of its consumption.
[0008] The main drawback of such devices obtained by inserting part of the hook into the
solid block, as well as exerting a determined compression to close the solid block
around the hook, lies in the non-perfect sealing of the coupling between the hook
and the solid block during the consumption of the solid block. In particular, the
contact area between the hook and the solid block is subjected to the delamination
phenomenon upon the repeated succession of flushed water over time and the progressive
consumption of the solid block. This phenomenon could cause the detachment of the
solid block from the hook and thus an early loss of the solid block before reaching
considerable consumption.
[0009] Lastly, other toilet hygienic devices in which the solid detergent and/or deodorant
means is enclosed by a sleeve-shaped container, which does not have any side wall
or side means for holding the solid block were developed. Such support container is
illustrated, for example, in document
US 2214798. The sleeve-shaped container is provided with a single hole through which the means
for hooking to the edge of the toilet are introduced and through which the flushed
water flows and is subsequently discharged through the two side ends of the sleeve
after just being touched by the upper portion of the detergent and/or deodorant means.
[0010] Though without side holding means, this type of sleeve-shaped container seems to
confer greater stability to the solid block with respect to the devices which provide
for one or more hooks inserted into the solid block. On the other hand, the main drawback
of this type of container seems to lie in the fact that the exposed surface of the
solid block, that is the surface on which the washing action of the toilet flush water
occurs, is rather limited.
[0011] Thus, an object of the present invention is to provide an improved hygienic device
for sanitary fixtures that is capable of overcoming the aforementioned drawbacks of
the prior art in an extremely simple, inexpensive and particularly functional manner.
[0012] In detail, an object of the present invention is to provide an improved hygienic
device for sanitary fixtures that is capable of exposing a considerable surface portion
of the solid detergent block to the washing action of the flushed water of the hygienic
device.
[0013] Another object of the present invention is to provide an improved hygienic device
for sanitary fixtures that is capable of efficiently holding the solid detergent block
when it is new and has not been used as well as when the relative overall volume reduces
progressively due to the washing action of the flushed water.
[0014] A further object of the present invention is to provide an improved hygienic device
for sanitary fixtures that is capable of minimising the amount of material required
for its manufacturing and, thus, the relative costs and the environmental impact due
to disposal.
[0015] These objects according to the present invention are obtained by creating an improved
hygienic device for sanitary fixtures as outlined in claim 1.
[0016] Further characteristics of the invention are highlighted by the dependent claims
which are an integral part of the present description.

[0018] With reference to the figures, some preferred embodiments of the improved hygienic
device for sanitary fixtures according to the present invention are shown in their
entirety with reference number 10. The device 10 is of the type comprising a detergent
and/or deodorant means 12 consisting of a block of solid material or in form of gel.
The detergent and/or deodorant means 12 can be manufactured using any known technology.
For example, if it is in solid form, such detergent and/or deodorant means 12 could
be manufactured through an extrusion or co-extrusion process.
[0019] In turn, the detergent and/or deodorant block 12 is made in the form of a body having
a cylindrical geometry provided with a pair of opposite bases 14 and 16 and a lateral
surface 18. The expression body having a cylindrical geometry is used to indicate
the location of the straight line generatrices, parallel to a predefined direction
and passing through the single points of a determined directrix curve, limited by
the two opposite bases 14 and 16, substantially parallel to the directrix. The directrix,
which is always a closed line, can be for example a circle, an ellipse, a polygon,
or it may generally be of any shape, as shown in the embodiments of the attached figures.
[0020] The device 10 comprises means 20 for hooking to a perimeter edge of a generic sanitary
fixture, such as for example a toilet. The hooking means 20 are preferably made up
of a first engaging portion 22 for engaging with the edge of the toilet, for example
shaped to form a flexible hook and which may vary in size and shape, and a second
portion 24 integral with a supporting element 26 capable of holding the detergent
and/or deodorant block 12 and at least partially enclosing the sole lateral surface
18 of such detergent and/or deodorant block 12, leaving the respective opposite bases
14 and 16 completely exposed.
[0021] Actually, according to the invention, the supporting element 26 consists conveniently
of a sleeve having as cross-sectional shape that of a generic flat geometric figure.
On the surface of the sleeve-shaped supporting element 26 a plurality of holes, openings,
slots and/or grooves 36 is advantageously obtained configured so that the detergent
and/or deodorant block 12 has a surface portion left uncovered, that is not enclosed
by the supporting element 26, equal to at least 50% of the overall surface of such
detergent and/or deodorant block 12, intended as the sum of the lateral surface 18
and the surfaces of the two opposite bases 14 and 16.
[0022] Preferably, the supporting element 26 is shaped so that the uncovered surface of
the detergent and/or deodorant block 12 is comprised between 51% and 60% of the overall
surface of such detergent and/or deodorant block 12. Such a configuration of the sleeve-shaped
supporting element 26 allows to obtain an efficient washing action of the flushed
toilet water on the surface of the detergent and/or deodorant block 12.
[0023] The sleeve-shaped supporting element 26 is thus provided with at least one base wall
28 (figures 5, 15 and 25), whereon the detergent and/or deodorant block 12 rests,
at least one upper wall 30 (figures 6, 16 and 26), to which the second portion 24
of the hooking means 20 is made integral, and at least one front wall 32 (figures
2, 12 and 22) and/or rear wall 34 (figures 3, 13 and 23), which connects such base
wall 28 to such upper wall 30.
[0024] According to the first three embodiments of the device 10, shown in detail in figures
1-30, the base wall 28 of the sleeve-shaped supporting element 26 has an extension
in length which is greater, or at least equal, to the overall length of the detergent
and/or deodorant block 12, intended as the distance between its opposite bases 14
and 16. This characteristic of the sleeve-shaped supporting element 26 not only allows
to efficiently support the detergent and/or deodorant block 12, even following consumption
and softening thereof due to use, but also to best manage the steps of manufacturing
and packaging the assembly constituted by such detergent and/or deodorant block 12
and the relative sleeve-shaped supporting element 26.
[0025] Still according to the first three embodiments of the device 10, the upper wall 30
of the sleeve-shaped supporting element 26 has an extension in length which is lower
than the extension in length of the base wall 28. Typically, the length of the upper
wall 30 can be comprised between about 1/2 and about 1/4 of the length of the base
wall 28. Hence, the front 32 and/or rear 34 walls are tapered from the bottom towards
the top.
[0026] The sleeve-shaped supporting element 26 can preferably be opened and for such purpose
it can consist of at least two distinct half-shells 26A and 26B, hinged to each other
and provided with means for mutual hooking, such as for example one or more teeth
40 provided on one of the two half-shells 26B which are introduced into one or more
corresponding holes 42 provided on the other half-shell 26A (figures 17-20). Thus,
the supporting element 26 is capable of passing from a closed configuration (figures
1, 11 and 21), in which the detergent and/or deodorant block 12 is held by such supporting
element 26, to an open configuration (figures 8, 18 and 28), in which the detergent
and/or deodorant block 12 can be extracted from such supporting element 26 or inserted
thereinto.
[0027] The sleeve-shaped supporting element 26 can also be provided therein with one or
more ribs 38 capable of blocking the axial sliding of the detergent and/or deodorant
block 12 with respect to the direction of development of such sleeve-shaped supporting
element 26. Alternatively or additionally to the ribs 38, the sleeve-shaped supporting
element 26 could be provided therein with one or more flexible arms (not shown), also
capable of blocking the axial sliding of the detergent and/or deodorant block 12 with
respect to the direction of development of such sleeve-shaped supporting element 26
even following a reduction of volume of the detergent and/or deodorant block 12 due
to use, because of the washing action of the flushed toilet water.
[0028] Preferably, as shown in figures 1-30, the supporting element 26 is made in the form
of a single sleeve, that is provided with respective single base 28, upper 30, front
32 and rear 34 walls. Thus, such single sleeve has a substantially closed cross-section
profile, except for the plurality of holes, openings, slots and/or grooves 36 it is
provided with.
[0029] Figure 31 shows an embodiment of the device 10 in which the supporting element 26
is made in the form of a single sleeve and in which the base 28, upper 30, front 32
and rear 34 walls of such sleeve have a substantially equal length.
[0030] Figure 32 shows another embodiment of the device 10 in which the supporting element
26 is made in the form of two sleeves separated and aligned along the same axis, joined
to each other by means of the second portion 24 of the hooking means 20.
[0031] Figure 33 shows a further embodiment of the device 10 in which the supporting element
26 is made in the form of a single sleeve with an open cross-section profile and it
is substantially C-shaped.
[0032] According to the latter three embodiments of the device 10, the overall length of
the sleeve-shaped supporting element 26 could be even lower than the overall length
of the detergent and/or deodorant block 12, still intended as the distance between
its opposite bases 14 and 16.
[0033] Still according to the latter three embodiments of the device 10, as well as the
embodiments of figures 1 and 11, the base 28 and upper 30 walls of the sleeve-shaped
supporting element 26, just like the relative front 32 and rear 34 walls, are parallel
two by two, so that such supporting element 26 substantially has the same geometric
shape of the detergent and/or deodorant block 12. The difference between the embodiment
of figure 1 and that of figure 11 solely lies in the fact that in the device 10 of
figure 1 the base 28 and upper 30 walls of the sleeve-shaped supporting element 26
have a width L smaller than the height H of the relative front 32 and rear 34 walls
(figure 4), while in the device 10 of figure 11 the base walls 28 and upper 30 of
the sleeve-shaped supporting element 26 have a greater width L than the height H of
the relative front 32 and rear 34 walls (figure 14).
[0034] Instead, according to the embodiment of the device 10 shown in figure 21, only the
base 28 and upper 30 walls of the sleeve-shaped supporting element 26 are parallel
to each other, while the relative front 32 and rear 34 walls are oriented so as to
maintain the detergent and/or deodorant block 12, which is substantially parallelepiped-shaped,
in an inclined position with respect to a vertical plane once the device 10 is applied
to the perimeter edge of the toilet.
[0035] It has thus been observed that the improved hygienic device for sanitary fixtures
according to the present invention attains the objects outlined above, thus allowing
to attain a considerable exposure of the surface of the detergent and/or deodorant
means to the washing action of the flushed toilet water, as well as considerable saving
in terms of plastic used for manufacturing the supporting element, but still efficiently
holding such detergent and/or deodorant means within the relative supporting element.
[0036] The improved hygienic device for sanitary fixtures of the present invention thus
conceived can be subjected to many modifications and variants, all falling within
the same inventive concept; furthermore, all details can be replaced with technically
equivalent elements. In practice, the materials used, as well as the shapes and dimensions,
may vary according to the technical requirements.
