Filed: 2021-06-14
Abstract: To provide bite-safe artificial teats free of choking hazards.SOLUTION: A nipple 12 of a bite-safe artificial teat 10 is constructed of soft and elastic polymeric materials to replicate a nursing mother's nipple tissue. Added to a soft and elastic matrix phase is a braided fibrous mesh tube to prevent a small bitten-off portion of the nipple from becoming separated from the rest of the teat, thereby preventing a choking hazard. The braided fibrous mesh tube is arranged in a very specific configuration, so that it experiences neither tension nor compression as the teat is compressed or elongated in use and does not act to reinforce the soft and elastic matrix phase which would otherwise create a classic load-transfer composite destroying the soft and elastic properties of the matrix phase needed for the desired functioning of the artificial teat.SELECTED DRAWING: Figure 2
