Abstract
An alkali-disposable ostomy bag 20 is disposed of in a wc 14 using a tablet 1 having
inner and outer portions. The inner portion 10 is of an alkai and this is covered by the outer
portion 11, which is a non-irritating mixture of a water-softening agent and a surfactant. The
tablet 1 can be handled safely by the user because the alkali 10 is covered by the outer portion
11.
Description
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.
It can be an advantage to be able to dispose of articles by flushing in a wc, particularly
where the articles are soiled, such as ostomy bags, sanitary items, diapers or the like. The
articles can be made of water-disintegratable material but this makes them vulnerable to
damage during use if they come into contact with water. It has been proposed instead to make
such articles from a material that is resistant to water but will break up on contact with an
alkali. Thus, the article would remain intact during use and could be exposed to water without
damage. When it is necessary to dispose of the article, an alkali is added to water in the wc
pan so that the article will be broken up sufficiently to be flushed away freely. The alkali
could be in the form of a liquid, powder or tablet. Examples of alkali-disposable ostomy bags
are described in GB2195919, GB2201372, GB2257056 and GB2324761.
Although such an arrangement for disposal can function satisfactorily, there is a
problem in ensuring that the user avoids contact with the alkali, since this could cause skin
irritation. Where the user needs to carry the alkali with him, this can be a particular problem.
Although the alkali can be in a dry form protected in a sachet or the like before use, there is
still a risk of contact with the alkali when it is removed from the wrapping. There can also be
a problem using alkali in hard water areas because the presence of calcium and magnesium
salts in the water renders the alkali less effective when attacking the article.
It is an object of the present invention to provide alternative disposal means.
According to one aspect of the present invention there is provided 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.
According to another aspect of the present invention there is provided 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.
A tablet for use in disposing of alkali-disposable ostomy bags will now be described,
by way of example, with reference to the accompanying drawing, in which:
- Figure 1
- is a perspective view of the tablet; and
- Figure 2
- illustrates the tablet in use.
With reference first to Figure 1 there is shown a tablet 1 of rectangular shape,
although it could be formed of any shape. 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.
With reference now also to Figure 2, 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. In use, 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. When the tablet 1 has dissolved, 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.
