Definitions

  • This invention relates to tablets for use in disposing of an article, the tablet including a first water-soluble substance capable of promoting disposal of an article when the article and tablet are immersed in water.
  • a tablet of the above-specified kind characterised in that the first substance is provided as an inner portion, that the tablet has an outer portion surrounding the inner portion of a second water-soluble substance different from the first substance, and that the second substance includes a water-softening agent and is substantially non-irritating to the skin such that the tablet can be handled safely by holding the outer portion prior to immersion.
  • the first substance preferably includes an alkali and the second substance is preferably a mixture of a surfactant and a water-softening agent.
  • the water-softening agent may be selected from a group comprising: ion-exchange resins, polycarboxylates, zeolites, sodium carboxylates, potassium carboxylates, phosphates, phosphites, phosphonates, sulphonates and sulphates.
  • the tablet may include an effervescent agent.
  • a method of disposing of an article including the steps of: providing a tablet including an inner portion of a first water-soluble substance capable of promoting disposal of the article when the article and tablet are immersed in water, and an outer portion surrounding the inner portion of a second water-soluble substance different from the first substance, the second substance being substantially non-irritating to the skin such that the tablet can be handled safely by holding the outer portion prior to immersion; placing the tablet in a wc pan such that the outer portion dissolves and allows the first substance to dissolve; placing the article in the wc pan so that it is broken down by the first substance; and flushing the wc.
  • the article may be an ostomy bag.
  • the first substance preferably includes an alkali.
  • the tablet 1 comprises two portions: and inner portion 10 and an outer layer or portion 11.
  • the inner portion 10 is of a water-soluble alkali, which may be either organic or inorganic in nature.
  • the outer portion 11 is of a substance that will not cause skin irritation and it completely surrounds the inner portion 10 so that the tablet can be handled safely, even by people with sensitive skin. More particularly, the outer portion 11 comprises a mixture of a surfactant and a water-softening agent.
  • the surfactant may be an ionic surfactant containing sodium dioctyl sulphosuccinate (eg Aerosol OT75 - Aerosol is a Registered Trade Mark of Cyanamid).
  • the water-softening agent may be, for example, selected from one or more of the following: ion-exchange resins; polycarboxylates; zeolites; sodium or potassium carboxylates; phosphates; phosphites; phosphonates; sulphonates and sulphates. With some water-softening agents, a surfactant may not be needed.
  • the water-softening agent may be mixed with another substance as a part of an organic or inorganic matrix or polymer. Prior to use, the tablet is protected in an outer foil or sachet 12.
  • the tablet 1 is shown used with an alkali-disposable ostomy bag 20, such as described in GB2195919, GB2201372, GB2257056 or GB2324761.
  • the construction of the bag 20 is not important to an understanding of the present invention, the bag being made of a conventional material that is resistant to water at neutral pH but that is broken up on contact with an alkali sufficiently to enable the bag and contents to be flushed away freely.
  • the tablet 1 is first removed from its wrapping 12 and is dropped in the pan 13 of a wc 14. Because the user only contacts the outer portion 11 of the tablet 1 he can handle the tablet safely.
  • the outer portion 11 of the tablet 1 containing the water-softening agent dissolves first in the water in the pan 13. When the underlying inner alkali 10 is exposed, this also starts to dissolve. The water will already have been largely softened by the outer layer 11 before the alkali 10 is dissolved, thereby increasing the effectiveness of the solution for degrading the bag 20.
  • the speed at which the tablet 1 dissolves may be further increased by adding an effervescent agent to either the inner, outer or both portions of the tablet.
  • the user drops the bag 20 into the water in the pan 13, in which the pH has now been raised to about 10.
  • the bag 20 is broken down by the alkali and, after a few minutes, can be flushed away without risk of blockage.
  • the arrangement of the tablet and article of the present invention therefore, makes the disposal of alkali-disposable articles easier for the user since the user does not have to take special precautions to avoid contacting the alkali.
  • the incorporation of a water-softening agent in the outer portion allows the solution to reach its optimum state quickly and, therefore, reduces the total time taken for disposal. This is an important advantage for users in that it reduces embarrassment.
  • the tablet could take various different forms and include various different substances.
  • the inner portion need not be of an alkali but could be of any other substance capable of promoting disposal of an article, for example, it could be an acid and used to dispose of acid-disposable articles.
  • the tablet could be used to dispose of various articles, such as sanitary wear, diapers or the like and is not confined to use with stoma bags.
