Description

Title of the invention: SANITATION DEVICE FOR TOILET BOWLS AND CORRESPONDING TABLET

[0001] The present invention relates to a device for cleaning and / or deodorizing toilet bowls, and a particularly effective cleaning and / or deodorizing tablet in the device, wherein said device has structural features such as to allow said tablet to be easily inserted therein. STATE OF THE ART

[0002] The toilet bowls to which the present invention can be applied are of different types, in particular toilets and urinals, and more preferably toilets.

[0003] As is known, there are various techniques for ensuring proper sanitation of toilet bowls. One of these involves the use of devices comprising a container that acts as a sort of cage inside which is placed a sanitation product (known in the industry as a "tablet") capable of gradually releasing one or more cleaning and / or deodorizing substances when it comes into contact with water. In particular, the device is attached to the sanitary fitting by means of a suitable hook, so that it is positioned at the point where the drainage water passes. Thus, when the water is drained, the latter is brought into contact with the tablet, which can then release the cleaning and / or deodorizing substances it contains.

[0004] In other words, a toilet bowl sanitation device comprises a container, a cleaning chemical and / or deodorizing tablet, and a hook for securing the device to a rim of a toilet bowl.

[0005] For the purposes of this document, the term "cleaner" refers to the ability to remove dirt and / or residue from a surface, as well as microorganisms such as bacteria and / or viruses that are removed along with the dirt itself. The term "deodorizer" refers to the ability to eliminate and / or correct unpleasant odors. The tablet may be in solid or semi-solid form (more particularly in gel form). It may have different geometric shapes, but is generally in the form of a rectangular parallelepiped.

[0006] As indicated, the container (which can have different geometric shapes, generally consistent with the shape of the tablet for reasons of optimizing the size of the device) has slots capable of allowing the passage of drainage water and the gradual release of the substances contained in the tablet. The said slots have a maximum width such that it prevents the tablet from coming out of the device.

[0007] In particular, in order to ensure good sanitation of the toilet bowl, it is important that:

[0008] • the tablet is well submerged by a flow of liquid and this depends, among other things, on the positioning of the device container relative to the toilet bowl;

[0009] • the liquid licks the surfaces of the tablet well;

[0010] • the liquid remains in contact with the surfaces of the tablet for a period of time sufficient.

[0011] Sanitation devices further generally include mechanisms / systems allowing the end user to replace the used tablet by inserting a new tablet without having to remove the device from the toilet bowl.

[0012] However, this operation is nevertheless very complicated, with repercussions on hygiene (since the user is in any case obliged to come into contact with the toilet bowl).

[0013] In addition, the wear of the tablet often results in a non-uniform pattern. Due to this non-uniform wear, the tablet takes on an irregular shape which is generally not appreciated by the end user (especially when the tablet has two or more different colors).

[0014] It should be noted that generally the flushing flow of a toilet bowl can be likened to a laminar flow of liquid flowing adjacent to an inner surface of a wall of the bowl. This flow of liquid outside the device should not be confused with the flow of liquid inside the device, even if the inner flow is derived from the outer flow, because the device is specially designed to intercept a portion of the liquid from an outer flow and circulate it within it. OBJECT OF THE INVENTION

[0015] The subject of the present invention is a device for toilet bowls comprising:

[0016] - a container comprising in turn:

[0017] o a front wall comprising a main opening for the insertion of a sanitizing tablet and a plurality of openings for the exit of liquid located in the lower portion of said front part;

[0018] o a rear wall comprising a plurality of openings for the inlet and outlet of liquid;

[0019] o an upper wall comprising a plurality of openings for the entry of liquid;

[0020] o a lower wall comprising a plurality of openings for the exit of liquid ;

[0021] o two side walls each comprising at least one opening for the inlet and / or outlet of liquid;

[0022] - a hook for fixing the device to a rim of a toilet bowl;

[0023] in which:

[0024] - said front wall, said rear wall, said top wall and said wall lower are shaped so as to define a housing chamber for receiving said tablet;

[0025] - said main opening is positioned such that its lower edge is positioned at a height at least equal to 40% of the total height of the front wall;

[0026] - said main opening has a height of between 25 and 60%, plus preferably between 35 and 55%, relative to the total height of said front wall and / or a width of between 50 and 99%, more preferably between 75 and 95%, relative to the total width of said front wall.

[0027] The overall objective of the present invention is to find a device which meets the above-mentioned requirements, in particular which meets them better than known solutions. DESCRIPTION OF DRAWINGS

[0035] As will be readily understood, there are various ways of practicing the present invention, which is defined in its main advantageous aspects in the appended claims and which is not limited by the detailed description below or by the appended drawings. DETAILED DESCRIPTION OF THE INVENTION

[0036] Figures 1 to 6 all refer to the same example embodiment of a device D for cleaning and / or deodorizing toilet bowls according to the present invention.

[0037] In these figures, the device D is shown in a position which essentially corresponds to the position which the device takes when it is fixed to a rim of a toilet bowl.

[0038] As indicated above, the device D comprises:

[0039] - a container 1 comprising in turn:

[0040] o a front wall 11 comprising a main opening 13 for the insertion of a sanitizing tablet 2 and a plurality of openings AA for the outlet of liquid located in the lower portion of said front part 11;

[0041] o a rear wall 12 comprising a plurality of openings AP for the inlet and outlet of liquid;

[0042] o an upper wall 15 comprising a plurality of openings AS for the entry of liquid;

[0043] o a lower wall 16 comprising a plurality of openings AI for the exit of liquid;

[0044] o two side walls 17a / 17b each comprising at least one opening AL for the inlet and / or outlet of liquid;

[0045] - a hook 3 for fixing the device D to a rim of a toilet bowl;

[0046] in which:

[0047] - said front wall 11, said rear wall 12, said upper wall 15 and said lower wall 16 are shaped so as to define a housing chamber CA for receiving said tablet 2;

[0048] - said main opening 13 is positioned such that its lower edge be positioned at a height at least equal to 40% of the total height of the front wall 11;

[0049] - said main opening 13 has a height HA of between 25 and 60%, more preferably between 35 and 55%, relative to the total height HTA of said front wall 11 and / or a width of between 50 and 99%, more preferably between 75 and 95%, relative to the total width LTA of said front wall.

[0050] In the present description and in the appended claims, the indications "frontal", "posterior", "lower", "upper", "front", "rear", "horizontal axis", "vertical axis" refer to the position that the device D takes when it is fixed to (a rim of) a toilet bowl.

[0051] It is important to consider that the rear wall is intended to rest on an interior surface of the toilet bowl and is therefore not visible to the user during normal use of the toilet bowl, while the front wall is adapted not to rest on an interior surface of the toilet bowl (i.e. to be distant therefrom, for example by 1.5 to 3 cm) and is therefore visible to the user during normal use of the toilet bowl.

[0052] In one embodiment, said device D comprises inside the housing chamber CA a tablet 2 of cleaning chemical and / or deodorizing product in order to fulfill its function.

[0053] Said tablet 2 can have any shape (regular or irregular), dimension and color. As regards the shape and dimensions of said tablet 2, they must obviously be consistent with the dimensions of the housing chamber CA and the main opening 13. Advantageously, the ratio between the surface area of the main opening 13 and the front surface area of the cleaner is between 60 and 90%, more preferably between 70 and 85%, even more preferably equal to 78%. This ratio allows easy insertion of the tablet 2 by the end user even when the device is anchored to the toilet bowl (which allows easy replacement of the used tablet) and, at the same time, ensures that the latter cannot come out of the housing chamber CA.

[0054] The device according to the present invention is therefore particularly advantageous because it allows the reuse of the container or cage which is refilled with new sanitation tablets. The device characterized by the refillable cage therefore makes it possible to market both a package comprising the cage with the tablet and exclusively tablet packages compatible with said cage, with obvious advantages in terms of biodurability and reduction of the use of plastic.

[0055] In a preferred embodiment, said tablet 2 has a parallelepiped shape. For example, said tablet 2 may have a parallelepiped shape with dimensions (LxHxD - length, height and depth) of 80-120 mm x 20-30 mm x 5-15 mm, more preferably 100 mm x 23.5 mm x 11 mm.

[0056] In a preferred embodiment, said tablet 2 has at least two colors. In another embodiment, said tablet 2 has a parallelepiped shape with at least two portions of different color (more preferably a blue portion and a green portion or, alternatively, a dark green portion and a light green portion). Said tablet 2 can be obtained, for example, by a process of coextrusion of two sections of the same dimension but of different color. Indeed, it has been observed that the presence of at least two portions of different colors is very appreciated by the end user.

[0057] As is known, the tablet 2 can only perform its cleaning and / or deodorizing function if the rear wall of the device D rests on an interior surface of a toilet bowl and if this interior surface is repeatedly subjected to a flow of liquid (thus allowing the tablet 2 to gradually dissolve in the as said liquid flows). Generally, said liquid is water or at least an aqueous solution.

[0058] The container 1 may have different shapes (regular or irregular) and dimensions. For example, the container 1 may have a shape substantially similar to a parallelepiped (optionally with the curved side walls 17a / 17b and with the upper wall 15 having a greater depth than the lower wall 16 and being provided with a curvature which makes this depth non-homogeneous along said wall), with dimensions (WxHxD - length, height and depth) of 110-150 mm x 25-50 mm x 10-30 mm, more preferably equal to 129 mm x 34 mm x 24 mm.

[0059] It should be noted that, in the case of curved walls, the dimensions indicated refer to the point of maximum extension. For example, the upper wall 15 and the lower wall 16 may have a length of 105-115 mm (more preferably 110 mm) while, due to the curvature of the side walls 17a / 17b, the total length of the container 1 is 125-135 mm (more preferably 129 mm). Even more preferably, the maximum length of the container 1 is positioned along the central portions of the side walls 17a / 17b.

[0060] As regards the depth of the container 1, the upper wall 15 may have a depth of 15-20 mm (more preferably 17 mm) at the level of the side walls 17a / 17b (i.e. in the peripheral portions of the upper wall 15) and a depth of 22-28 mm (more preferably 24 mm) at the point of maximum depth (which is advantageously positioned in the central portion).

[0061] Said openings AA, AP, AS, AI, AL, 13 may be located only at a peripheral area of the wall concerned, or only at a central area of said wall, or at both a peripheral area and a central area of said wall. It should be noted that the openings designed for the inlet of liquid are essentially positioned in the upper portions of the device, while the openings designed for the outlet of liquid (and of the substances released by the tablet) are essentially positioned in the lower portions. In any case, it is not excluded that, under certain operating conditions, there may be a flow of liquid leaving the openings designed for the inlet of liquid and / or a flow of liquid entering the openings designed for the outlet of liquid entering the pocket through one or more of them.

[0062] In particular, the liquid vortices that form inside the housing chamber CA promote homogeneous contact of the liquid with the outer surfaces of the tablet. In this way, uniform wear of the tablet 2 can be achieved in all types of toilet bowls. The device D according to the present invention thus makes it possible to maintain a regular shape of the tablet 2 for long periods. periods of time, a feature highly valued by end users (especially when the tablet features two or more different colors).

[0063] The position, shape and / or dimensions of the openings AA, AP, AS, AI, AL are extremely important to ensure that the tablet 2 does not come out when drainage water passes through.

[0064] The same applies to the main opening 13, which must however have a position, a shape and dimensions allowing easy insertion of the tablet 2 by the end user.

[0065] The shape of the different openings AA, AP, AS, AI, AL, 13 may be variable. In particular, the shape and dimensions of said openings AA, AP, AS, AI, AL, 13 may vary both between different walls and with respect to the same wall (as illustrated in Figures 1 to 6, where the openings are mainly of regular shape).

[0066] Advantageously, the front wall 11, which is the wall visible to the end user once the device is positioned in the toilet bowl, may comprise one or more openings of a particular shape, for example decorative elements, logos and / or letters. In particular, the letter-shaped openings may be positioned adjacent to each other so as to form words (see, for example, [Fig.l], in which there are 5 letter-shaped openings to form the word "WC NET").

[0067] Advantageously, the front wall 11 may have additional openings AA positioned in the extreme lower portion which allow, with the openings AI present in the lower wall 16, a total exit of the water accumulated inside the housing chamber CA, thus preventing the tablet 2 from floating up from the bottom of the chamber itself. This phenomenon can in fact cause the tablet 2 to exit the housing chamber CA through the main opening 13, especially when the tablet 2 has already been used in large quantities (thus having rather reduced dimensions which can facilitate the exit of the tablet through the main opening 13). For example, there may be 4 openings in the right portion and 4 openings in the left portion of the front wall 12. Said openings may be rectangular in shape with dimensions (WxH) of 5-10 mm x 1-2 mm, more preferably 8 x 1.6 mm.

[0068] As for the main opening 13, it may have a shape similar to a rectangle, with one or two side edges optionally curved with a certain outward curvature to maximize the surface area of the opening itself.

[0069] The curvatures present on the lateral edges may be symmetrical or asymmetrical with respect to each other. Preferably, the lateral extension maximum opening is positioned in the central or upper portion of the side edges.

[0070] Said main opening 13 is positioned such that its lower edge is positioned at a height equal to at least 40% of the total height of the front wall 11. For example, said lower edge is positioned at a height of between 40 and 80%, more preferably between 45 and 60% of the total height of the front wall 11.

[0071] In this way, the tablet 2 can be prevented from coming out during the flow of drainage water and, at the same time, easy insertion of the tablet 2 by the end user can be allowed.

[0072] The main opening 13 may have dimensions (WxH) of 100-120 mm x 15-20 mm, more precisely 108.3 x 17 mm.

[0073] The rear wall 12, which is not visible when the device is fixed to the toilet bowl, may comprise a high number of AP openings or in any case a series of AP openings with a high total surface area in order to maximize the inlet and / or outlet of liquid, thus facilitating the flow of liquid and, consequently, obtaining homogeneous wear of the tablet 2 regardless of the type of toilet bowl.

[0074] In one embodiment, these openings AP have a rectangular shape. In particular, said openings AP have a height HP of between 40 and 90%, more preferably between 45 and 75%, relative to the total height HTP of said rear wall 12 and / or a width BP of between 0.25 and 5%, more preferably between 1 and 3%, relative to the total width LTP of said rear wall 12.

[0075] In another embodiment, said openings AP are located both at a peripheral zone and at a central zone of said rear wall 12.

[0076] In one embodiment, a first series API of said openings AP has a first height HP1 of between 40 and 55% of the total height HTP of said rear wall 12 and a second series AP2 of said openings AP has a second height HP2 of between 55 and 75%.

[0077] More preferably, said first series API and said second series AP2 of said AP openings are positioned such that each opening of the first series API is positioned between two openings of the second series AP2 and vice versa (see, for example, [Fig.2], where the height of the adjacent openings varies alternately between two values).

[0078] In one embodiment, the AP openings located at the peripheral zone have a width of dimensions smaller than those of the AP openings located at the central zone of said rear wall 12, even more preferably of dimensions between 50 and 75% relative to the width of the AP openings located at the central zone of said rear wall 12. The AP openings positioned at the peripheral zone may have a width of dimensions between 0.25 and 1.5% relative to the total width LTP of said rear wall 12.

[0079] For example, as illustrated in [Fig.2], the rear wall 12 may have a total of thirteen rectangular-shaped openings AP with an alternating height of 20-24 mm and 15-18 mm (more precisely 22.45 and 16.45 mm). The width of said openings AP may be 1-3 mm (more precisely 1.95 mm) for the two openings positioned at the end of the wall 12 and 2-4 mm (more precisely 2.95 mm) for the remaining eleven openings AP. Indeed, this arrangement has proven particularly advantageous for facilitating the flow of water inside the housing chamber CA and the uniform wear of the tablet 2 regardless of the type of toilet bowl.

[0080] The upper wall 15, which is (at least partially) visible when the device is attached to the toilet bowl, may comprise a high number of AS openings or in any case a series of AS openings with a high total surface area in order to maximize the ingress of liquid, especially considering the reduced (essentially zero) risk of the tablet 2 exiting through these AS openings. In one embodiment, said plurality of AS openings of said upper wall 15 has a rectangular shape and is positioned at said plurality of AP openings of said rear wall 12. For example, as illustrated in [Fig.4], the upper wall 15 may have a total of eleven AS openings of rectangular shape. Said AS openings may be positioned in correspondence with the AP openings of the rear wall (possibly also having the same width).

[0081] In one embodiment, the upper wall 15 may have a certain curvature which makes the depth of the container 1 non-homogeneous (see for example [Fig.4]). Said curvature which obviously also extends along the rear wall 12, may be integral with the curvature of the surface of the toilet bowl. In this way, the volume of the housing chamber CA can be increased without, however, significantly increasing the size of the container 1 relative to the toilet bowl itself.

[0082] As indicated above, the upper wall 15 may have, for example, a depth of 15-20 mm (more preferably 17 mm) at the level of the side walls 17a / 17b and a depth of 22-28 mm (more preferably 24 mm) at the point of maximum depth (which is advantageously positioned in the central portion).

[0083] The lower wall 16, which will be difficult to see when the device is attached to the toilet bowl, may comprise a large number of openings AI or in any case a series of openings AI having a high total surface area in order to maximize the liquid outflow (this in order to also reduce the risk of the water remaining in the housing chamber CA lifting the tablet 2). For example, as illustrated in [Fig.6], the bottom wall 16 may have a total of eight rectangular-shaped openings, four of which are in the right portion and four in the left portion (preferably in an offset position relative to the openings AP present in the rear wall 12 in order to improve the flow inside the housing chamber CA).

[0084] In one embodiment, the upper wall 15 has a greater depth than the lower wall 16. See, for example, the side view of [Fig. 5], where the profile of the container 1 has essentially a rectangular trapezoid shape. Furthermore, as already seen, the upper wall 15 is provided with a curvature which makes the depth of the container 1 non-homogeneous along said wall.

[0085] One or both side walls 17a / 17b may have a certain curvature, for example to increase the volume of the housing chamber CA. The curvatures in the side walls 17a / 17b may be symmetrical or asymmetrical with respect to each other (preferably symmetrical).

[0086] As illustrated in [Fig.5], the two side walls 17a / 17b may each comprise three openings AL: a first opening for the liquid inlet is positioned in the upper portion of the wall; a second opening for the liquid inlet and / or outlet is positioned essentially halfway up the wall and a third opening for the liquid outlet is positioned in the lower portion of the wall. Said openings AL may be rectangular in shape. For example, said openings AL may have a height and / or a width (understood as depth when looking at the device from the front) of 1-5 mm.

[0087] As indicated above, the upper wall 15 and the lower wall 16 may, for example, have a length of 105-115 mm (more preferably 110 mm) while, due to the curvature of the side walls 17a / 17b, the total length of the container 1 is 125-135 mm (more preferably 129 mm). Even more preferably, the maximum length of the container 1 is positioned along the central portions of the side walls 17a / 17b.

[0088] Advantageously, inside the housing chamber CA there are elements such as projections and / or reliefs to ensure that no surface of the tablet 2 is completely in contact with the inner walls of the container 1. This is because said phenomenon results in a reduction of the cleaning and / or deodorizing power of the tablet itself, since the surface available for contact with water is reduced (with consequently a lower release of the substances from the tablet). This aspect becomes particularly relevant in the case of tablets containing cleaning substances which also have properties adhesive: in this case, in fact, one or more surfaces of the tablet could remain attached to the inner wall of the container 1, with a cleaning and / or deodorizing power (at least partially) compromised.

[0089] In one embodiment, said front wall 11 and said bottom wall 16 are hinged by means of one or more hinge elements CE, preferably two hinge elements CE, so as to make said housing chamber CA accessible. The end user can thus access the housing chamber CA more easily, for example to carry out cleaning operations of the device D more easily and more efficiently and / or to position the tablet 2 more easily when the device is not anchored to the toilet bowl. In another embodiment, said front wall 11 can be reversibly hooked to the top wall 15 by means of special hooking elements, so as to ensure the closure of the housing chamber CA.

[0090] The hook 3 may comprise a shaped slat, formed of three elongated sections 3A, 3B, 3C connected to each other by two elbows 3D, 3E and to the container by another elbow 3F.

[0091] In one embodiment, said other elbow 3F is located 10-25 mm from a point of maximum protrusion of said front wall 11.

[0092] Said first elongated section 3A of said shaped slat has a length of 60-80 mm and / or a second elongated section 3B of said shaped slat has a length of 40-60 mm and / or a third elongated section (3C) of said shaped slat has a length of 30-50 mm.

[0093] The shaped slat, in particular its components 3A, 3B, 3C, has an essentially constant width (e.g. 3-12 mm, in particular about 8 mm).

[0094] Preferably, said elbows 3D, 3E, 3F have a radius of between 2 and 15 mm.

[0095] As is known, the section of the slat determines (for the same material as that from which it is composed) the flexibility and elasticity of the latter, thus contributing to the fixing of the device to the toilet bowl.

[0096] Attaching the device to the toilet bowl (in particular to the rim of the bowl) is important for the device to perform its function properly. In particular, after attachment, the container of the device must be positioned such that it can be effectively submerged by the flow of liquid (thus ensuring that said flow of liquid also submerges the tablet).

[0097] Furthermore, it is desirable that the fixing be adequate regardless of the shape and dimensions of the toilet bowl (in particular the shape and dimensions of the rim of the bowl).

[0098] One of the aspects that most influences the support of the container 1 of the device on the inner surface of the toilet bowl is the distance between the starting point of the elbow 3F (at the junction with the section 3A) and the point of maximum protrusion of the rear wall 12 (distance that can be appreciated, for example, by looking at [Fig.5]). In fact, this distance determines the “leverage” effect of the part of the container 1 on the elbow 3F by the effect of an inner surface of a wall of the toilet bowl on which the device D is applied. This distance can, for example, be 25 to 40 mm.
