This topic is about finding a specific appliance that can help with the disposal of used ostomy pouches by sealing them in a way that contains odors. The person is looking for a product that uses a continuous plastic-bag roll to seal the pouches, similar to a system they remember but can't find. They are not interested in a vacuum sealer meant for food preservation but rather a canister system that effectively traps odors.

Here are some helpful insights and advice shared by others:

1. For a similar system used for cat litter:
- The "Litter Locker" is a product that uses a continuous plastic-bag roll to trap odors. It can be found on eBay and other online sites.

2. For baby diaper disposal systems:
- The "Diaper Genie" by Playtex is available in Canada and the US. It can be found in the baby-supply aisles of department stores and online.
- There are two models mentioned: Diaper Genie I, which is no longer available in retail stores but can be found inexpensively on eBay, and Diaper Genie II. Users have noted that these models seal odors well, are easy to use, and can be opened from both the top and bottom.

3. How these canister systems work:
- You insert the waste through the top of the canister. Inside, a continuous plastic sleeve captures the waste. When the sleeve is full, you tear off the section and tie it. This method does not require heat-sealing, and it effectively contains odors.

4. An alternative suggestion, though not what the original poster wanted, was a FoodSaver countertop heat-vacuum sealer. However, this was deemed unsuitable for waste disposal purposes.
