This is a container for a bar of soap, of the approximate size of a bar of soap. Inside there is a platform that is raised by springs towards the open face of the container. The large open face of the container is surrounded by a watertight rubber seal. Once a bar is inserted, the bar is pressed towards
the opening so that a single sudsy soap face is exposed. As the bar is depleted from use, the platform raises towards the opening until there is no more soap remaining. A message written upon the platform serves as a reminder to purchase more soap, as scouring oneself with the container alone is not satisfactory.

But the soap shrinks laterally as well as
thicknessly - surely, if most of the face of
soap is exposed initially, it will pop out
through the hole as it shrinks? |
|
| |
Also, I can't see how you'd actually use
this. If I'm washing my hands, the whole
bar needs to be exposed. If I'm washing
my body, it might work, but I'd rather use
the bar in its naked state. I don't see the
advantage of this. |
|
| |
The advantage is in what you just mentioned. It is to prevent waste. The purpose is to stop the bar from dissolving in the way you describe by only exposing a single side of the bar to water. Why would it shrink laterally otherwise? If you require the entire surface of the device to have cleansing properties perhaps it could be composed of pumice, cloth other abrasive surface. |

I think MB was confused by the "soap dish" reference, perhaps not fully realizing this idea was for the dish to hold the bar of soap from the moment you unwrap it until it is all used up. It's kind of a soap holder/applicator instead of just a dish. |
|
| |
Why not just stick the soap in a tube and use the end of the bar, like deodorant? Much easier to design and handle, especially if you give the sleeve some grippy-when-wet-and-soapy surface. (Another plus - no more dropping the soap, unless you really intend to, that is) |
|
| |
And please explain what's wrong with soap-on-a-rope? Doesn't it get worn down evenly? Isn't it always handy? And there's no need for a written "buy more soap" reminder. When all you have left is rope, you know you need more soap! |
|

I thought this was going to be a Möbius shaped soap dish. |
|
| |
It's going to be harder than you think to make this. Which is to say expensive--it may take quite some time to save enough soap to pay for the thing. Soap doesn't cost all that much, and doesn't wash off the bar and down the drain at any great rate, in my experience. |
|
| |
Using it sounds awkward, and probably involves getting a hair or two yanked out. My soaping style involves running the bar over my skin, which would be impossible with this idea. I think this device is aimed at people who use a washcloth and wipe it across the soap, maybe. They could, instead, just use a regular soap dish out of the stream of the shower spray. |
|

There are many alternatives to bar soap, already. I don't see anything good about this way to use bar soap. [ ] |

//I think MB was confused by the "soap
dish" reference, // No, I get the
reference. When the soap is installed,
you've basically got a soap-bar-shaped
plastic box, with one face being the
exposed soap. And this exposed face
will have a sort of a 'frame' around it,
this being the rim that holds the bar in.
Yes? |
|
| |
OK, so now think about how the soap
dissolves and erodes. If only the
exposed face erodes, then before long
that face is going to be recessed with
respect to the edges of the bar (which
are behind the rim), and then it's no
use. Or, if the whole bar tends to
erode, it will become narrower and
shorter as well as thinner, until it
escapes from the retaining rim. It's a
lose-lose situation. |
|
| |
In any event, I agree with Baconbrain -
it's not going to be convenient or
particularly economical. If you buy
properly-made soap which has been
dried properly (not the cheap
commercial stuff), it does not dissolve
so readily, and is not so wasteful. |
|
| |
Maybe one of these would be a good investment for the other 80%+ who must buy the cheap commercial soap on a regular basis? |
|
| |
//the other 80+% who must buy the cheap
commercial soap on a regular basis// This
is very depressing news. |
|
| |
To address the technical issues, I think the soap will absorb some water dissolving the edges, which will be forced outwards due to the upward pressure. Perfectly designed. |
|
| |
Have you ever come across a soap-saver in the form of a sort of soft, rounded plastic cage, about the size of a new soap bar, which holds the remnants of several old bars? I remember it working surprisingly well, and it has fewer moving parts than this idea. |
