US patent number 4,443,200

Continuing my poopy-patent of yesterday, we look at US patent number 4,443,200. This is a "toilette training device" described as:
"Disclosed is a toilet training device for toilet training of children, embodied as an animal, such as a bear, having a lower torso having anterior and posterior chambers with upper access ports for filling the anterior chamber with water and the posterior chamber with soft material. Upon sufficient pressure being applied to the anterior chamber, a lower valve opens to allow the water to pass therethrough representing urine; and upon sufficient pressure being applied to the posterior chamber, a lower valve opens to allow such soft material to pass therethrough representing stools."
So, in short, this is a stuffed animal that can poop and pee. "The squeezing pressure applied to such posterior chamber is similar to the pressure experienced in human defecation."
