Benefits of technology

[0007] It is another object of the present invention to provide such a cassette in which the flexible tube has barrier properties that substantially reduce malodor from discarded diapers.
[0009] It is a further object of the present invention to provide such a flexible tube material that is inexpensive and easy to manufacture.

Problems solved by technology

However, the odor reduction capability of a tubing formed of Formosa resin is limited by its permeability.
Less permeable materials have not been employed in the art because they are ill-suited for the conversion process in which film from a roll is inserted into a cassette.
Less permeable materials are brittle and the insertion process creates splits or openings in the film.
Also, the rigidity of less permeable materials renders them ill-suited to the twisting required for operation of a cassette.
Additionally, an increased amount of tubing can be fitted into each cassette, thereby prolonging use.

Embodiment Construction

[0023] An organic permeation study was undertaken to provide barrier characteristics of various films for human fecal matter. This data was developed by performing an isostatic transmission rate study.

[0024] The organic compounds shown in Table 1 were combined in equal amounts by volume. The multi-component mixture and the films were placed in a remote cell as illustrated in FIG. 1. The top sides of the films were continuously swept with a nitrogen carrier gas in order to prevent any decrease in concentration gradient across the film.

3TABLE 1 Table 1 shows the organic permeants used for the permeation study. COMPOUND CLASS 1-Pentanethiol C5 mercaptan Valeric acid C5 organic acid p-cresol Substituted phenol Indole Aromatic heterocycle

[0025] The carrier gas stream was periodically monitored to determine whether equilibrium had been reached. Once equilibrium was achieved, the results were recorded. A MOCON ARMATRAN II equipped with a capillary column and a flame ionization detector (FI...

Abstract

A film is provided for use in a cassette. Preferably, the cassette is used in a waste disposal system. The film is a high density polyethylene film resin having both a low melt index and a high density, thereby providing improved odor control capabilities and enhanced tear strength and assembly strength.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a flexible tubing for use in a cassette dispenser for a diaper or similar waste disposal device. More particularly, the present invention relates to barrier films used for flexible tubing in such cassettes.[0003] 2. Description of the Prior Art[0004] Diaper disposal devices have become popular for the convenient and sanitary disposal of diapers and related waste. A conventional diaper disposal device has a pail that serves as a storage chamber accessed via a closable lid and, a cassette positioned in the pail and having a tubular core with a length of flexible tube stored in the core. The diaper disposal system operates by depositing a soiled diaper into the pail, rotating the core, and twisting the flexible tube to create a seal above the diaper. A second diaper may be disposed of by opening the lid, inserting the second diaper, and pushing the previous sealed diaper further into the storage chamber. A new seal...
