Abstract

A unit dose package for applying a material with an applicator having a separate material and applicator portion. In one embodiment, a plurality of material wells is used to mix different materials to be dispensed with an applicator. In an embodiment the plurality of material wells are concentric. In another embodiment a portion of the cover is removable. In another embodiment, a material well is squeezed to dispense the material onto an applicator.

Claims

1. A single dose disposable dispenser for dispensing a material to be applied with an applicator comprising:

a tray having a material well and an applicator well;

an applicator placed in the applicator well;

a wall formed in the material well dividing the material well into a plurality of chambers, said wall being deformable permitting selective combining of the plurality of chambers; and

a cover covering the material well and said applicator well,

whereby different materials are capable of being separated until desired to be mixed together and applied with said applicator.

2. A single dose disposable dispenser as in claim 1 wherein:

the plurality of chambers are concentric.

3. A single dose disposable dispenser as in claim 1 wherein:

one of said plurality of material wells contains a base; and

another one of said plurality of material wells contains a catalyst.

4. A single dose disposable dispenser as in claim 1 further comprising:

an opening between said tray and said cover through which the handle of said applicator extends outwardly of the applicator well with the handle of said applicator extending beyond an edge of said tray and said cover, and inwardly extending end portions that extend towards one another to define a space less than a diameter of the handle of said applicator, whereby any unintentional lateral separation of said applicator and said tray is resisted.

5. A single dose disposable dispenser as in claim 1 further comprising:

frangible portions formed in said cover defining a strip extending over the material well.

6. A single dose disposable dispenser as in claim 1 further comprising:

a releasable portion between the material well and an edge of said tray, whereby the material is capable of being forced there through upon squeezing the material well,

whereby the material is capable of being applied directly to an applicator portion of said applicator.

7. A single dose disposable dispenser for dispensing a dental material to be applied in a dental procedure with an applicator comprising:

a tray having a material well and an applicator well formed therein;

an applicator placed in the applicator well;

a wall formed in the material well dividing the material well into a first chamber and a second concentric chamber,

a first material placed within the first chamber;

a second material placed within the second concentric chamber, said first material reacting with said second material when combined;

said wall being deformable permitting selective combining of the first and second materials; and

a cover covering the material well and said applicator well,

whereby first and second materials are capable of being separated until desired to be mixed together, reacted, and applied with said applicator.

8. A single dose disposable dispenser for dispensing a material to be applied with an applicator comprising:

a material to be applied;

an applicator having an applicating end portion and a handle;

a tray having a material well adapted to receive and containing said material to be applied and an applicator well adapted to receive and hold the applicating end portion of said applicator; and

a cover attached to said tray covering the material well and said material and the applicator well and the applicating end portion of said applicator,

the applicator well having an opening between said tray and said cover through which the handle of said applicator extends outwardly of the applicator well with the handle of said applicator extending beyond an edge of said tray and said cover, and inwardly extending end portions that extend towards one another to define a space less than a diameter of the handle of said applicator, whereby any unintentional lateral separation of said applicator and said tray is resisted.

9. A single dose disposable dispenser for dispensing a material to be applied with an applicator comprising:

a tray having a material well and an applicator well;

a material placed in said material well;

an applicator placed in said applicator well; and

a cover covering said material well and said applicator well, said cover having a releasable portion between the material well and an edge of said tray, whereby said material is capable of being forced there through upon squeezing the material well,

whereby the material is capable of being applied directly to an applicator portion of said applicator.

10. A single dose disposable dispenser for dispensing a material to be applied with an applicator as in claim 9 wherein:

the releasable portion comprises a weakened portion formed between said cover and said tray.
