Abstract

There is described a device, e.g. a toilet training device, comprising a thermochromic composition sandwiched between a transparent first layer and a second layer wherein the second layer is provided with an adhesive layer on its outer surface.There is also described a method of toilet training using such a device.

Description

Toilet Training Device
The present invention relates to a novel toilet training device and to methods associated therewith.
Young boys are usually toilet trained by first teaching them to urinate sitting down and then the progress to urinating standing up. It is well known that many young boys experience difficulty in learning the correct discipline and frequently miss the lavatory and thereby urinate on the floor surrounding the lavatory. Advice to parents often includes playing "sink the battleship" by floating a flushable target, such as a few pieces of an O-shaped breakfast cereal (e.g. Cheerios®) on the surface of the water in the toilet bowl. This gives the boy a target to aim at.
However, it is clearly desirable to provide a more permanent "target" in the toilet bowl.
The normal temperature of urine is approximately that of body temperature at 370C ± 0.50C and the effect of the difference between this temperature and the ambient temperature has already been utilised in some products. Thus, for example, US Patent No. 5,389,093 describes a reusable wetness indicating cloth diaper which uses a thermally sensitive indicator to indicate that the diaper has become soiled. The diaper uses a thermochromic ink to indicate a temperature change in the diaper when it comes into contact with warm urine. More recently, US Patent No. 5,809,590 describes a waterproof urinal mat which contains a humorous or informational message printed or coated over with a thermochromic ink composition that is opaque at ambient temperature and changes to transparent at its activation temperature. Whilst the invention described therein is suitable as a urinal device capable of a display of information, it does not address the desire of providing an incentivised target for toilet training young boys and is also disadvantageous in that it utilises thermochromic composition that become transparent rather than simply change colour.
We have now invented a simplified semi-permanent badge may be provided in a toilet basin which is capable of a colour change when it makes contact with warm liquid and change back to its original colour when the badge cools down or comes into contact with a cooler liquid.
Thus, according to a first aspect of the invention, we provide a device, e.g. a badge, comprising a thermochromic composition sandwiched between a transparent first layer and a second layer wherein the second layer is provided with an adhesive layer on its outer surface.
In the device of the invention the first and second layers may each comprise a plastics material, which may be the same or different. Preferentially, the second layer is a substantially opaque layer.
Where possible, materials are selected such that these are not affected by the pH of urine (which may range from 4.5 to 8). Preferably, the thermochromic composition is such that the composition changes from one colour to another colour upon temperature change (as opposed to changing from colourless to coloured). Furthermore, it is preferred that the thermochromic material is an inherently reversible thermochrome. The use of a reversible thermochromic material is advantageous in that, inter alia, there is no necessity to include a desensitising material.
In a preferred aspect of the invention, the thermochromic material comprises one or more thermochromic transition metal salts. Such salts may comprise copper or mercury salts. Mercury salts are preferred. Such mercury salts may be mercurous or mercuric salts. A preferred mercuric salt is mercury (II) oxide. Conventionally known mercurous salts may be used, however preferred salt are the mercurous halides, such as mercury (I) bromide or mercury (I) iodide.
Especially preferred, thermochromic materials may be selected from one or more of mercury (I) iodide (which changes from light yellow to red upon heating and returns to light yellow upon cooling), mercury (I) bromide (which changes from white to yellow upon heating and returns to white upon cooling), mercury (II) oxide (which changes from yellow to black upon heating and returns to yellow upon cooling) and copper (II) sulphate pentahydrate (which changes from blue to colourless upon heating and return to blue upon cooling).
The adhesive layer should preferentially comprise one or more adhesives suitable for use in a wet environment. Furthermore, it is preferred that the adhesive should be substantially resistant to urine. A preferred group of adhesives are the polyisobutene based adhesives which are considered to be very effective, even on lightly soiled surfaces, because of their high oil absorption capacity and their good ability to bind fillers. Any conventionally known polyisobutene adhesives may be used, but a preferred adhesive is the Oppanol® adhesive, or a mixture of Oppanol® adhesives, available from BASF.
Polyisobutenes are available as low molecular weight, medium molecular weight and high molecular weight. In a preferred aspect of the invention, the polyisobutene is a high molecular weight polyisobutenes, for example such as is used in adhesive plasters, e.g. having a molecular weight of 1,000,000-1,500,000 (viscosity average molecular weight).
The device of the invention may also advantageously include a luminescent material. The luminescent material may be a phosphorescent material. Examples of such a luminescent material which may be included in the device of the present invention may be, for example, zinc sulphide, e.g. as fine crystals of. Copper may optionally be added as an activator. Such a composition may be depicted as ZnS: Cu. Other optional phosphorescent pigments may be selected from one or more of CaS :Bi, CaStS:Bi and ZnCdS:Cu. The preferred phosphorescent pigment of the present invention is one or more ZnS based pigments are available from United Mineral & Chemical Corp., Lyndhurst, NJ, USA. Such pigments may provide a varied daylight body colour, e.g. natural (green emitting) [6SSU], yellow [GSS 205/1], orange-yellow [GSS 207/1], orange [GSS 305/1], rose [GSS 507/1], green [GSS 905/1], blue [GSS 8B/1], natural (yellow emitting) [GSR]5 orange (orange emitting) [GSR 115/2], white (blue emitting) [BAS] and blue (blue emitting) [BAS 5025/1].
The functional (thermochromic/luminescent) components of the present invention may be laminated between two plastics sheets. Any conventionally known clear plastics material may be utilised. Furthermore, the adhesives coated plastics sheets may comprise the same or different plastics to the non-adhesives visible (in use) sheet. A preferred plastics sheet may be high density polyethylene/ or high density polypropylene. Alternatively, the components of the present invention may be microencapsulated.
When the components are encapsulated, the preferred microencapsulation technology comprises the use of an amino resin. Although urea and thiourea resins may be used, a preferred microencapsulation resin is a melamine resin and especially a melamine formaldehyde (MF) resin.
Depending upon the nature of the use of the device of the invention, the plastics laminate may be formed in a variety of shapes. Thus, for use as a toilet training device, the laminate may be, for example, in the shape or design of a cartoon or fun character. Alternatively, the device may be adapted for use as an entertainment article for use, e.g. in men's urinals, in which case, a great variety of designs may be utilised.
According to a yet further aspect of the invention, we provide a method of toilet training which comprises the use of a device as hereinbefore described. As previously mentioned, the method of the invention is especially suited for young boys. We further provide the use of a thermochromic material in the manufacture of a device as hereinbefore described.
The invention will now be described by way of example only and with reference to the accompanying drawings in which Figure 1 is a schematic representation of the badge of the invention in use.
Example 1 A calculated amount of melamine and formaldehyde was introduced into a 250 ml flask. The reaction mixture was heated to 60 0C until the solution became transparent. The basic recipe for the preparation of MF prepolymer is given in Table 1.
