Generic Body Wash Bottles

[I'm using Dove, because it's widely available and pretty representative.]

Body wash bottles are generally pretty similar. They are meant to be stored upright, and you must tip them upside-down to dispense the soap, while giving the bottle a squeeze. The major problem with these bottles is that when the bottle starts becoming empty, the remaining soap collects at the bottom of the bottle, and the few seconds of tipping it upside-down during your shower are not sufficient to get it to flow down to the spout. And you also have to squeeze vigorously and shake it (just like the getting-ketchup-out-of-a-Heinz-bottle struggle).

Obviously, there are several ways to get around this. If your bottle's top is flat (as shown below in an older incarnation of Dove), you can simply store the near-empty bottle upside-down all the time (and let gravity do the work for you). If the bottle top is round (as shown in the current incarnation of Dove below), you're out of luck.

Better body wash bottle designs exist - including the pump-top (like for many hand soaps) and the bottom-dispensing types (shown below for Pantene conditioner).

Note that bottles are used for other things such as lotions, condiments, adhesives, etc. and many of these products share packaging and packaging shortcomings.
