Abstract
A sealed tampon package and continuous process for making the package. Heat seals, preferably hermetic longitudinal and cross seals, are preferably peelable. The tampon is sealed under sufficient negative pressure to snugly retain the tampon in place without crushing or misshaping the tampon, yet without bursting the package under normal external pressures realized during storage. The tampon package will remain sealed during normal wear and tear, yet is easily opened when desired by peeling the seals.
Claims15
A hermetically sealed, moisture-proof tampon package which resists inadvertent opening and maintains the package integrity, thereby preventing damage and contamination to the tampon, comprising:
- a length of thermoplastic material entirely enclosing the tampon, the thermoplastic material formed into a flexible wrapper;
- the wrapper having two opposed hermetic longitudinal seals formed along its length and two opposed hermetic cross-seals, the seals being formed by applying pressure at sealing zones located at opposed edges on the package and heating the sealing zones to a temperature and for a time sufficient to form longitudinal and cross seals that are hermetic around the entire periphery of the package;
- wherein a hermetically sealed individually wrapped tampon is produced which is under negative pressure sufficient to retain the tampon snugly within the package without crushing or misshaping the tampon;
- and
- wherein at least one of the cross-seals and the longitudinal seals are manually peelable.
A sealed, moisture-proof tampon package which resists inadvertent opening and maintains the package integrity, thereby preventing damage and contamination to the tampon, comprising:
- a length of thermoplastic material entirely enclosing the tampon, the thermoplastic material formed into a flexible wrapper;
- the wrapper having two opposed longitudinal heat seals formed along its length and two opposed cross-seals comprising heat seals, the heat seals being formed by applying pressure at sealing zones located at opposed edges on the package and heating the sealing zones to a temperature and for a time sufficient to form longitudinal and cross heat seals around the entire periphery of the package;
- wherein a heat sealed individually wrapped tampon is produced which is under negative pressure sufficient to retain the tampon snugly within the package and to cause the package to substantially conform to the shape of the tampon without crushing or misshaping the tampon;
- and
- wherein at least one of the cross-seals and the longitudinal seals is manually peelable.
