Abstract:
A method for manufacture of a sealed, disposable container and associated puncturing device for use with a baby bottle, said baby bottle having a threaded nipple ring and nippple disposed in said nipple ring and a threaded baby bottle housing for threadedly receiving said nipple ring, said method comprising the steps of:providing a sterilized cup portion having a generally cylindrical closed side wall, a closed bottom formed across said cylindrical closed side wall, and an open top, and also having an outwardly protruding flange formed circumferentially about the open top dimensioned and configured for association with the top of said baby bottle housing; depositing within said sterilized cup portion a quantity of breastmilk; applying a puncturable first ply across said flange of the cup portion such that a hermetically sealed chamber containing said breastmilk is formed with said closed side wall and closed bottom; affixing a relatively unpuncturable second ply onto said puncturable first ply, said second ply having a circular puncturing portal formed therein for access to said first ply, and said second ply otherwise providing protective coverage for said first ply from accidental or unintentional breaking of the first ply: and associating a puncturing device with said cup and plies, said puncturing device comprising a round conduit with a top end and a bottom end, said bottom end of the conduit having a point for puncturing said first ply exposed through said puncturing portal, said puncturing device further comprising a circular disk disposed about said top end which is dimensioned and configured sufficiently to allow said puncturing device to be received by a friction fit into said baby bottle nipple ring, said cup portion being dimensioned and configured to received in and on said baby bottle housing, and said puncturing device being dimensioned and configured such that when said puncturing device is frictionally received in said baby bottle nipple ring and said sealed disposable container is associated with said bottle housing and said nipple ring is screwed down on said threads of said bottle housing, said pointed bottom end of said conduit engages and punctures said inner seal upon assembly of the baby bottle, the length of the conduit exceeding the diameter of the puncturing portal so that when said nipple ring is fully threaded onto said bottle housing, a circular flap of the first ply, formed by pressing the conduit through the puncturing portal, is prevented from being drawn back into the conduit by liquid flow, and wherein the length of the conduit is shorter than the depth of the threads on said baby bottle nipple ring such that the first ply is not punctured by the pointed end of the conduit until thread engagement between said nipple ring and said baby bottle has started.
