1. A packaging article for storing and dispensing flowable components, comprising:
a first chamber defined by a sealed connection between a first film and a second film, wherein the first chamber has a first cross-sectional area at the second film;
a second chamber defined by a sealed connection between the first film and the second film, wherein the second chamber is connected to the first chamber by a first rupturable seal;
a third chamber defined by a sealed connection between a third film and a fourth film, wherein the third chamber has a second cross-sectional area at the third film, and wherein at least about 75% of the first cross-sectional area overlaps the second cross-sectional area; and
a fourth chamber defined by a sealed connection between the third film and the fourth film, wherein the fourth chamber is connected to the third chamber by a second rupturable seal.
2. The packaging article of claim 1, wherein at least about 90% of the first cross-sectional area overlaps the second cross-sectional area.
3. The packaging article of claim 1, and further comprising:
a first passageway that connects the second chamber to an exterior portion of the packaging article, wherein the first passageway is defined by the sealed connection between the first film and the second film; and
a second passageway that connects the fourth chamber to an exterior portion of the packaging article, wherein the second passageway is defined by the sealed connection between the third film and the fourth film.
4. The packaging article of claim 3, wherein the first passageway is not parallel to the second passageway.
5. The packaging article of claim 1, wherein the first film and the fourth film are each made from a material selected from a group consisting of aluminum, polypropylene, polyethylene, polyethylene terephthalate, and combinations thereof.
6. The packaging article of claim 1, wherein the first chamber contains a first flowable component and the third chamber contains a second flowable component, and wherein an application of pressure to the first chamber and the third chamber dispenses the first flowable component and the second flowable component in a substantially simultaneous manner.
7. The packaging article of claim 6, wherein the first flowable component is dispensed into the second chamber and the second flowable component is dispensed into the fourth chamber.
8. The packaging article of claim 1, and further comprising a dispensing device, wherein the dispensing device comprises a member that is disposed between the first film and the fourth film.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A security element for a secured document, comprising:
a masking structure intended to decrease visibility of a surface of the element when the latter is present within the document or on a surface of the document, the masking structure comprising a mixture of at least two nanoscale fillers of one or more pulverulent compounds, the D50 average size of the at least two nanoscale fillers ranging from 1 nm to 1000 nm.
2. The element as claimed in claim 1, the element forming a security thread, a foil, a patch, a flake, or a fiber.
3. The element as claimed in claim 1, the element having two opposite major faces and the masking structure decreasing the visibility of at least one of said faces.
4. The element as claimed in claim 1, said at least two nanoscale fillers each having a D50 size ranging from 30 nm to 1000 nm.
5. The element as claimed claim 1, said at least two nanoscale fillers having different refractive indices.
6. The element as claimed in claim 1, one of said at least two nanoscale fillers comprising colloidal silica.
7. The element as claimed in claim 6, said colloidal silica being present in an amount by weight ranging from 20% to 80% relative to the weight of the masking structure.
8. The element as claimed in claim 1, one of said at least two nanoscale fillers comprising titanium dioxide.
9. The element as claimed in claim 8, said titanium dioxide being present in an amount by weight ranging from 1% to 40% relative to the sum of the weights of said at least two nanoscale fillers.
10. The element as claimed claim 1, the thickness (t) of the masking structure ranging from 2 microns to 30 microns.
11. The element as claimed in claim 1, the nanoscale fillers being dispersed in a binder within a layer of the masking structure.
12. The element as claimed in claim 1, comprising a security structure superposed at least partially, on the masking structure.
13. The element as claimed in claim 1, comprising a carrier made of a thermoplastic material.
14. The element as claimed in claim 12, the security structure being located on one side of the carrier and the masking structure on the other side.
15. The element as claimed in claim 12, the security structure and the masking structure being located on a same side of the carrier.
16. The element as claimed in claim 1, said masking structure further comprising a multilayer interferential pigment comprising a mineral base coated with at least one layer of a refractive index different from that of the base.
17. The element as claimed in claim 16, the amount by weight of multilayer interferential pigment relative to the weight of the masking structure ranging from 1% to 40%.
18. The element as claimed in claim 16, the size of the multilayer interferential pigment ranging from 2 microns to 150 microns.
19. The element as claimed in claim 1 further comprising a luminescent agent, mixed in a layer of the masking structure.
20. The element as claimed in claim 1, comprising a heat-sealing adhesive making contact with the masking structure.
21. The element as claimed in claim 20, the adhesive comprising a luminescent.
22. The element as claimed in claim 1, comprising a luminescent agent within a layer distinct from the masking structure.
23. A document incorporating the security element as claimed in claim 1.
