Benefits of technology

The patent describes a flexible outer web that can be used in a dispenser for compacted flexible tubing. The flexible web is designed to compress the tubing when in a closed state, and to allow the tubing to be uncompacted and dispensed from the dispenser when in an open state. The flexible web acts as a guide when the dispenser is placed onto a hollow shaft of a waste disposal apparatus, and avoids damage to the tubing. The use of a flexible web in the dispenser saves packaging, makes it lighter, and more adaptable to different shapes of units in a waste disposal apparatus.

Problems solved by technology

However, the current dispensers that are commercially available will often have a rigid outer plastic casing, which adds to waste.
Compacting and packaging the currently available tubing can be a difficult and complex operation, which adds to the cost of production.

Embodiment Construction

[0037]Preferable and optional features of the aspects will now be described. Any preferable or optional feature may be combined with any aspect, and with any other preferable or optional feature.

[0038]First Aspect

[0039]The flexible tubing preferably comprises a flexible material, such as a material suitable for forming a bag for accepting waste. The flexible tubing is preferably formed from a tube of film, which may be a plastic film. The material of the tubing, which may be or comprise a plastic film, is preferably a film having a thickness of 0.5 mm or less, optionally 0.2 mm or less, optionally 0.1 mm or less, optionally 75 μm or less. The material of the tubing, which may be or comprise a plastic film, is preferably a film having a thickness of from 10 μm or more, optionally from 10 μm to 100 μm, optionally from 20 μm to 50 μm, optionally from 20 μm to 40 μm. The film of the tubing may comprise, consist essentially of, or consist of a polymer selected from, for example, polyethy...

Abstract

Herein is described a dispenser of flexible tubing, for fitting to a waste disposal apparatus. The dispenser may include a compacted flexible tubing in the form of a ring; the ring typically having an aperture extending therethrough. The dispenser may comprise a flexible outer web and / or the flexible tubing, in uncompacted form, may have first and second ends, wherein, in use, the flexible tubing can be dispensed from the dispenser, such that the first end can be passed through the aperture, and the dispenser is adapted to prevent the second end of the tubing passing through the aperture of the tubing.

Description

[0001]This application relates to a dispenser of flexible tubing, for fitting to a waste disposal apparatus, including, but not limited to, a toilet.BACKGROUND[0002]Some types of waste disposal apparatus include a flexible tubing that fits within the apparatus and can be dispensed as necessary. Such waste disposal apparatus includes ‘waterless’ toilets and nappy / diaper disposal units. A waterless toilet is one that does not require water to flush, and can be useful as portable toilets or in regions where water is scarce. In such toilets, the flexible tubing is folded and stored in a concertina fashion in an annular shape, the annular shape typically corresponding to an open aperture in the top of the toilet. The tubing can be sealed at one end, then can be fed downwards through the toilet housing via, for example rollers, that pinch the edge of the bag. Such a waterless toilet is described in US 2009 / 0255045.[0003]Recent developments include a toilet that allows for the separation o...
