Description of the Invention
(21) With reference to the figures, the hygienic protector, particularly for the collection and separation of human solid excrement, generally designated by the reference numeral 1, is configured to be at least partially inserted into the opening 2 of a toilet bowl 3, or of another device for the collection of human solid excrement, and comprises a central portion 4 and a peripheral portion 5. The central portion 4 defines a container body 6 for the collection and retaining of human solid excrement, and is configured to be accommodated inside the opening 2 of the toilet bowl 3. The peripheral portion 5 is configured to protrude externally with respect to the rim of the opening 2 of the toilet bowl 3. The central portion 4 and the peripheral portion 5 are provided in a water-soluble and biodegradable material. The container body 6 comprises an opening 7 that is shaped like the opening 2 of the toilet bowl 3.
(22) According to the invention, the hygienic protector 1 comprises at least one anti-odor membrane 10, 11 that extends over the central portion 4, so as to close the opening 7 of the container body 6. According to the invention, the anti-odor membrane 10, 11 is provided in a material that is water-soluble, biodegradable and heat-sensitive, which is adapted to puncture upon contact with the solid excrement expelled by the user 8, substantially at the area of contact between the anti-odor membrane 10, 11 and the solid excrement.
(23) Advantageously, the central portion 4, which defines the container body 6, is configured to collect and retain the solid excrement for an interval of time that is sufficiently long to enable the user 8 to dispose of the hygienic protector 1, containing the solid excrement, in the septic tank.
(24) The membrane 10, 11 advantageously has an anti-odor function, in that it prevents, or at least limits, the egress, from the container body 6, of the unpleasant odors that are generated by the excrement.
(25) The hygienic protector 1 is advantageously made of a water-soluble and biodegradable material; however, at least the anti-odor membrane 10, 11, and possibly also the peripheral portion 5, are made of a material that, in addition to being water-soluble and biodegradable, is also heat-sensitive.
(26) The term water-soluble is used here to mean a material that is soluble in water; the term biodegradable is used here to mean a material that undergoes biological decomposition; and the term heat-sensitive is used here to mean a material that is affected by the action of heat.
(27) In other words, the hygienic protector 1 has a programmed solubility in water, in which the central portion 4 that defines the container body 6 dissolves completely in water in an appreciably longer time than the time required for the complete dissolving in water of the anti-odor membrane 10, 11 and possibly also than the time required for the complete dissolving in water of the peripheral portion 5.
(28) Advantageously, the hygienic protector 1 is made of an ecologically compatible material, i.e. non-polluting.
(29) Advantageously, furthermore, the hygienic protector 1 is made of a biodegradable material originating from one or more of the following products: discarded tomato skins, seaweed, sugars, potatoes and polyvinyl alcohol.
(30) Advantageously, moreover, the anti-odor membrane 10, 11 can be made of a material that is completely soluble in water at a water temperature of at least more than 10 C.
(31) Just as advantageously, the central portion 4, which defines the container body 6, can be made of a material that is completely soluble in water at a water temperature of at least more than 40 C.
(32) The peripheral portion 5 of the container body 1 can be made of a material that is completely soluble in water at a water temperature of at least more than 10 C. or, alternatively, of a material that is completely soluble in water at a water temperature of at least more than 40 C.
(33) The different temperature of complete water-solubility in water is linked both to the speed with which the material is capable of dissolving in water, and to the heat sensitivity of the material proper. In other words, a material that is completely soluble in water at a water temperature of at least more than 10 C. is adapted to puncture, almost instantly, upon contact with humid feces having a temperature of approximately 37 C., while a material that is completely soluble in water at a water temperature of at least more than 40 C. is adapted to withstand contact with humid feces having a temperature of approximately 37 C.
(34) The material that is completely soluble in water at a water temperature of at least more than 40 C. also tends to dissolve in cooler waters, but with significantly longer time intervals.
(35) Advantageously, both the central portion 4 and the anti-odor membrane 10, 11 are made of a material that is configured to puncture upon contact with the urine released by the user 8.
(36) In particular, a jet of urine at 37 C. is capable of locally dissolving, practically instantly, a material that is completely soluble in water at a water temperature of at least more than 10 C., and, sufficiently quickly, also a material that is completely soluble in water at a water temperature of at least more than 40 C.
(37) In this manner, the urine expelled by the user 8 creates one or more holes that pass through the hygienic protector 1, and in particular the anti-odor membrane 10, 11 and the central portion 4 that defines the container body 6, thus creating the conditions for evacuating the air that may accumulate inside the hygienic protector 1, and in this manner preventing the floating thereof when it is flushed by the flow of water activated by the user 8 for the disposal of the hygienic protector 1 and the excrement.
(38) The anti-odor membrane 10, 11 can be made of a material that has a thickness comprised between 10 and 30 micrometers. Preferably the anti-odor membrane 10, 11 has a thickness of 16 micrometers.
(39) The central portion 4 can be made of a material that has a thickness comprised between 20 and 70 micrometers, and preferably a thickness comprised between 30 and 50 micrometers.
(40) The heat-sensitivity and water-solubility properties of the material used to make the anti-odor membrane 10, 11, or the central portion 4 that defines the container body 6 of the feces, or indeed the peripheral portion 5, also vary as a function of the thickness of the material proper, where a greater thickness confers lower heat-sensitivity and lower water-solubility.
(41) For example, the thickness of the material used to make the central portion 4 is such as to prevent the puncturing thereof upon contact with feces, while still enabling the dissolving thereof in water in relatively long intervals of time, while the thickness of the material used to make the anti-odor membrane 10, 11 is such as to make possible an almost immediate puncturing thereof upon contact with the feces, as well as the dissolving in water in relatively short intervals of time.
(42) Advantageously, the central portion 4 is made of a material that is configured to dissolve completely in water in a time interval comprised between 3 and 15 minutes, at a water temperature of at least more than 10 C.
(43) Advantageously, the membrane 10,11 is made of a material that is configured to dissolve completely in water in a time interval comprised between 5 and 120 seconds, at a water temperature of at least more than 10 C.
(44) In particular, the central portion 4 is configured to arrive at a complete dissolving only after the hygienic protector 1 has reached the septic tank, which occurs in a time interval of the order of minutes (for example between 3 and 15 minutes), while the anti-odor membrane 10, 11 must be able to puncture immediately on contact with the feces, and therefore its dissolving times in water will also be much shorter, in the order of seconds (for example between 5 and 120 seconds).
(45) The type of basic material used to make the anti-odor membrane 10, 11, the central portion 4 and the peripheral portion 5 can advantageously be the same, if however the choice, conveniently combined, of different thicknesses and different degrees of solubility makes it possible to provide materials that have different properties of water-solubility and heat-sensitivity.
(46) Advantageously, the central portion 4 that defines the container body 6 is made of a heat-shrink material, so that the surface of the central portion 4 upon contact with solid excrement having a temperature of approximately 37 C. contracts and wraps at least partially around that solid excrement. In this manner, the solid excrement that reaches the bottom 60 of the container body 6 will be at least partially wrapped by the material of which the central portion 4 of the hygienic protector 1 is made, thus reducing the surface of the excrement that remains in free contact with the surrounding air and thus further limiting the emanation of the miasmas generated by the excrement, in addition to what is already achieved by the anti-odor membrane 10, 11.
(47) As shown in
(48) Advantageously, the peripheral portion 5 completely covers the entire upper surface of the toilet seat 17, where present.
(49) In this manner, the user 8 is completely isolated from any accidental contact with any part of the toilet bowl 3 or parts thereof.
(50) Advantageously, the peripheral portion 5 also comprises portions 54 which protrude laterally, which, in the configuration for use, protrude laterally with respect to the toilet bowl 3. In the configuration for use, thanks to the protruding portions 50, 52 and 54, the static and balanced positioning of the hygienic protector 1 on the toilet bowl 3 is ensured. In particular, the protruding portions 50, 52 and 54 which fall from the edges of the toilet seat 17 balance the weight of the central portion 4, thus preventing the hygienic protector 1 from falling inside the toilet bowl 3. Obviously, when the user 8 sits on the toilet bowl 3, the hygienic protector 1 is kept in position by the weight of the user 8.
(51) Furthermore, the size of the hygienic protector 1, and the extent of the protrusion of the protruding portions 50, 52 and 54 of the peripheral portion 5 with respect to a toilet bowl 3, are such as to ensure that in any angular position in which the hygienic protector 1 is applied with respect to the toilet bowl 3, the sitting surface is always completely covered, and the intimate parts of the user are always safeguarded.
(52) Furthermore, as shown in
(53) Advantageously, furthermore, the bottom 60 of the container body 6 has, in cross-section, at least one V-shaped profile and preferably a W-shaped profile, designated with the reference numerals 61 and 62. The W-shaped profile is configured to convey and collect the solid excrement at a specific point, i.e. at one of the apices of such profile 61 or 62, in order to favor the at least partial wrapping of the solid excrement by the walls of the container body 6, thus reducing the surface of the excrement that remains in free contact with the surrounding air.
(54) As illustrated by way of example in
(55) As illustrated by way of example in
(56) The hole 12 can also have a diameter of approximately 4 cm. Such hole 12 is sufficiently wide to allow the solid excrement to pass rapidly into the container body 6, and at the same time is sufficiently narrow to prevent the unpleasant odors generated by the solid excrement that is present in the container body 6 from spreading to the surrounding environment.
(57) Advantageously, the container body 6 can also comprise an anti-odor substance.
(58) According to the first embodiment, schematically illustrated in
(59) Such hygienic protector 1, according to the first embodiment, is particularly adapted to be applied to toilet bowls of the type of sitting flush toilets.
(60) The method for providing the hygienic protector 1 illustrated in
(61) In this manner, the peripheral portion 5, which isolates the user 8 from contact with the toilet bowl 3, and the membrane 10, with the anti-odor function, are made of a material that is designed to dissolve rapidly, once in water, while the central portion 4, which has to collect and wrap the feces, is designed to dissolve completely only after the hygienic protector 1 has reached the septic tank, thus withholding the miasmas generated by the feces until these reach the septic tank.
(62) In particular,
(63) According to a first variation of the first embodiment, which is schematically illustrated in
(64) In this case, the edges of the anti-odor membrane 10 are bonded to the edges of the opening 7 of the container body 6.
(65) The method for providing the hygienic protector 1 illustrated in
(66)
(67) The two anti-odor membranes 10 and 11 are configured to convey the expanding gas originating from the solid excrement into two different volumes 13 and 14, further decreasing the spread of the unpleasant odor generated by the excrement to the external environment.
(68)
(69) In particular, the hygienic protector 1 according to the second embodiment is configured to abundantly cover at least the lower part of the lid 15 of the toilet bowl 3.
(70)
(71)
(72) In all the embodiments, the hygienic protector 1 can be provided 90% in a material that is rapidly water-soluble and the remaining 10% in a material that is slowly water-soluble. This is a direct consequence of the fact that the sole portion of the hygienic protector 1 that is made of a slowly water-soluble material is only the central portion 4 which defines the container body 6 of the feces.
(73) As illustrated in
(74) The operation of the hygienic protector, according to the invention, is clear and evident from the foregoing description.
(75) The hygienic protector 1 can be supplied to the user 8, folded repeatedly on itself, inside the envelope 101 of the travel kit 100.
(76) The user 8 takes out the hygienic protector 1, unfolds it, and applies it to the toilet bowl 3, with the container body 6 inside the toilet bowl 3. The user 8 can apply the hygienic protector in any angular position with respect to the toilet bowl 3, in that the extension of the peripheral portion 5 is such as to cover the toilet seat 17 in any case.
(77) When the user 8 urinates, the jet of urine is such as to create holes in the material of the hygienic protector 1, which will favor the correct expulsion of air that may be trapped in the container body 6 at the moment of disposal into the septic tank, by way of the flow of water.
(78) The feces that are expelled by the user 8 determine the puncturing of the anti-odor membrane 10 and are collected on the bottom 60 of the container body 6, in particular at one of the two V-shaped profiles 61 or 62.
(79) At this point, the heat of the feces is such as to determine a contraction of the heat-shrink material from which the container body 6 is made, to the point that the feces are at least partially wrapped by the walls of such container body 6. The feces are thus isolated both from the external environment and from contact with the internal surfaces of the toilet bowl 3, since they are contained in the container body 6.
(80) When the user 8 has finished using the toilet, he/she allows the hygienic protector 1 to fall into the water present in the toilet bowl 3.
(81) As soon as the hygienic protector 1 is immersed in water the dissolving process begins, which will be very fast for the anti-odor membrane 10 and the peripheral portion 5 of the hygienic protector 1 if made of a rapidly water-soluble material, and will be slower for the central portion 4 that defines the container body 6, which preferably has to remain sufficiently intact for an interval of time that is such as to allow the container body 6 to reach the septic tank. Inside the septic tank, within a few minutes, the central portion 4 that defines the container body 6 will dissolve completely as well. As soon as the hygienic protector 1 comes into contact with the water present in the toilet bowl 3, all of the components thereof that are made of a rapidly water-soluble material, which can constitute up to 90% of the total material from which the hygienic protector 1 is made, will dissolve almost immediately. In this manner, the flow of water activated by the user 8 has to dispose of only the part of central portion 4 that has not yet dissolved in water, although it has already been at least partially reduced in volume and it has already begun to soften, passing from a solid consistency to a viscous consistency.
(82) In addition to this, since the container body 6 not only has a function to separate the feces, but also a function to collect them, in that it routes them and conveys them to the apex of the V-shaped profile 61, 62, the expulsion of the feces into the septic tank is favored, in that the feces, collected and retained by the container body 6, once in the water, do not tend to spread out. In this manner a reduced flow of water is sufficient in order to flush the feces into the septic tank, through the drain hole of the toilet bowl 3.
(83) In practice it has been found that the hygienic protector, particularly for the collection and separation of human solid excrement, according to the present invention, achieves the intended aim and objects in that it makes it possible to safeguard the intimate parts of users and also the hygiene and cleanliness of toilet bowls.
(84) Another advantage of the hygienic protector, according to the invention, consists in that it is able to completely isolate the user from accidental contact with the toilet bowl and from any bothersome splashes of dirty water.
(85) Another advantage of the hygienic protector, according to the invention, consists in that it retains the unpleasant odors that are generated by the solid excrement upon contact with air, and thus it keeps the surrounding environment healthy without having to resort to wasteful electrical ventilation apparatuses.
(86) Another advantage of the hygienic protector, according to the invention, consists in that it is easily adaptable to the various different types of toilet bowl and bedpans, as well as to all types of users, independently of their size.
(87) Another advantage of the hygienic protector, according to the invention, consists in that it reduces the volume of water required, in respect of current toilet bowls, for the disposal of the feces, since they are concentrated in a well-defined region of the container body, and are held there until they reach the septic tank.
(88) Another advantage of the hygienic protector, according to the invention, consists in that it avoids the use of chemical products, generally aggressive towards the environment, which are necessary for cleaning the surfaces of toilet bowls or of bedpans for urine and feces.
(89) The hygienic protector thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
(90) Moreover, all the details may be substituted by other, technically equivalent elements.
(91) In practice the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements.
(92) Where the technical features mentioned in any claim are followed by reference numerals and/or signs, those reference numerals and/or signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference numerals and/or signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference numerals and/or signs.
