Abstract
A packaged dental article includes a dental appliance that is precoated with an adhesive. The adhesive is in contact with a flexible film having a low adhesion surface. The film is secured to a container at a location spaced from the appliance so that the film tends to peel away from the adhesive when the appliance is removed from the container in order to inhibit separation of the adhesive from the appliance. The container has a sidewall with a recess that engages a carrier to hold the container, and the carrier is flexible to permit the container to be inserted into or released from the carrier when desired.
Claims21
An article comprising:
- a container having a substrate and a well;
- a dental appliance received in said well of said container, said dental appliance having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section and a second section spaced from said first section, said first section including a low adhesion surface in contact with said adhesive;
- and
- means for securing said second section to said substrate while said first section is substantially free of direct connection to said substrate such that said first section is movable away from said substrate during release of said adhesive from said film.
3 more elements
An article comprising:
- a substrate;
- a dental appliance having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section and a second section spaced from said first section, said first section including a low adhesion surface in contact with said adhesive;
- and
- means for securing said second section to said substrate while said first section is substantially free of direct connection to said substrate such that said first section is movable away from said substrate during release of said adhesive from said film, wherein said film has a normally flat configuration and normally lies in face-to-face, flat contact with said substrate.
3 more elements
An article comprising:
- a substrate;
- a dental appliance having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section and a second section spaced from said first section, said first section including a low adhesion surface in contact with said adhesive;
- and
- means for securing said second section to said substrate while said first section is substantially free of direct connection to said substrate such that said first section is movable away from said substrate during release of said adhesive from said film, wherein said film comprises fluorinated ethylene propylene copolymer, and wherein said film is etched.
3 more elements
An article comprising:
- a substrate;
- a dental appliance having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section and a second section spaced from said first section, said first section including a low adhesion surface in contact with said adhesive;
- means for securing said second section to said substrate while said first section is substantially free of direct connection to said substrate such that said first section is movable away from said substrate during release of said adhesive from said film;
- and
- a container having a cover, and wherein said substrate presents a bottom of said container.
4 more elements
An article comprising:
- a substrate;
- a dental appliance having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section and a second section spaced from said first section, said first section including a low adhesion surface in contact with said adhesive;
- means for securing said second section to said substrate while said first section is substantially free of direct connection to said substrate such that said first section is movable away from said substrate during release of said adhesive from said film;
- and
- means for supporting said first section over said substrate in such a manner that full face-to-face contact of said first section with said substrate is avoided.
4 more elements
An article comprising:
- a substrate;
- a dental article having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section including a low adhesion surface in contact with said adhesive, said first section extending over a portion of said substrate;
- and
- means for supporting said first section over said portion of said substrate in such an orientation that full face-to-face contact of said first section with said portion of said substrate is avoided, wherein said means for supporting said first section comprises a pyramid, peak or bump on said substrate.
3 more elements
An article comprising:
- a substrate;
- a dental article having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section including a low adhesion surface in contact with said adhesive, said first section extending over a portion of said substrate;
- and
- means for supporting said first section over said portion of said substrate in such an orientation that full face-to-face contact of said first section with said portion of said substrate is avoided, wherein said substrate includes a ridge, and wherein said means comprises said ridge.
3 more elements
An article comprising:
- a substrate;
- a dental article having an exterior surface;
- an adhesive on said exterior surface;
- a flexible film having a first section including a low adhesion surface in contact with said adhesive, said first section extending over a portion of said substrate;
- and
- means for supporting said first section over said portion of said substrate in such an orientation that full face-to-face contact of said first section with said portion of said substrate is avoided, wherein said means for supporting said first section comprises a roughened, scuffed or scribed upper surface on said substrate.
