Abstract
A toilet training article in the form of a toilet training pad containing an effervescent agent is disclosed. The toilet training pad, which may be an insertable pad or integrated directly into an undergarment, contains an effervescent agent which releases gas upon being contacted by urine. The effervescent agent may be in the form of a compound containing a substantially inert gas, or may be a combination of compounds that, upon being contacted by urine, produce a gas.
Claims56
A process for manufacturing an article, the article in the form of a pad comprising a pliable substrate and an effervescent agent encapsulated in a shell material, the shell material being capable of releasing the effervescent agent when wetted with urine, the substrate having a body side face and an outside face, the body side face facing the skin of the wearer when the article is worn, the effervescent agent comprising a matrix structure comprising a sugar compound and having cells distributed therein which contain a gas under pressure, the process comprising:
- mixing the effervescent agent with an adhesive;
- and
- applying the mixture onto the substrate and allowing the mixture to dry.
A process for manufacturing an article, the article in the form of a pad comprising a pliable substrate and an effervescent agent encapsulated in a shell material, the shell material being capable of releasing the effervescent agent when wetted with urine, the pliable substrate including a gas-permeable fibrous matrix, the effervescent agent comprising a matrix structure comprising a sugar compound and having cells distributed therein which contain a gas under pressure, the process comprising:
- depositing the effervescent agent onto the gas-permeable fibrous matrix;
- and
- passing a gas through the gas-permeable fibrous matrix to force the effervescent agent to become entrapped in the fibrous matrix.
