Unitized package of card and fluid vessel
View Patent ↗The invention generally relates to unitized packages for containing and dispensing a product material. In particular, the unitized packages comprise a printed base card and a fluid vessel permanently bonded to the printed base card. The fluid vessel comprises a first laminate barrier layer comprising at least one layer of a biaxially oriented thermoplastic polymer, a portion of which is formed into a modified dome shape, and a planar second laminate barrier layer. The first and second laminate barrier layers are sealed together to form a fluid-tight enclosure, wherein the product material substantially fills the enclosure and the modified dome shape is resiliently sustainable. A method of manufacturing the unitized packages as described above is also provided. In particular, the method includes forming a portion of the first laminate barrier layer comprising the biaxially oriented polymer into the modified dome shape using a force such as pressurized gas.
1. A unitized package comprising:
(a) a printed base card; and
(b) a fluid vessel comprising (i) a first laminate barrier layer comprising at least one layer of biaxially oriented thermoplastic polymer, (ii) a product material, and (iii) a second laminate barrier layer,
wherein a portion of the first laminate barrier layer is planar and a portion of the first laminate barrier layer has been pre-formed into a modified monolithic dome shape by biaxial elongation of the first laminate barrier layer, wherein the modified monolithic dome shape has a defined volume, and the product material substantially fills the defined volume, in which the modified monolithic dome shape is pre-formed before the product material substantially fills the defined volume, wherein the second laminate barrier layer is planar, wherein the first and second laminate barrier layers are sealed together at their perimeters to form a fluid-tight enclosure for containing the product material, and
wherein the second laminate barrier layer is permanently bonded to a portion of the printed base card.
2. The unitized package of claim 1 , wherein the modified dome shape of the first laminate barrier layer is resiliently sustainable when the fluid vessel is sealed.
3. The unitized package of claim 1 , wherein the biaxially oriented thermoplastic polymer comprises one or more of a polyethylene, a polypropylene, a polyester, a polyamide, a polyacrylate, or a mixture thereof.
4. The unitized package of claim 3 , wherein the biaxially oriented thermoplastic polymer comprises a polyethylene terephthalate.
5. The unitized package of claim 1 , wherein one or both of the first and second laminate barrier layers comprise a layer of aluminum foil.
6. The unitized package of claim 5 , wherein the aluminum foil is less than about 0.001 inches in thickness.
7. The unitized package of claim 1 , wherein the product material is a liquid.
8. The unitized package of claim 1 , wherein the fluid vessel comprises a dispensing tip.
9. The unitized package of claim 8 , wherein the base card comprises an opening strip.
10. The unitized package of claim 9 , wherein the opening strip is defined by a first line of perforation that intersects the dispensing tip.
11. The unitized package of claim 10 , wherein the base card comprises a second line of perforation intersecting the dispensing tip, in which the second line of perforation defines a folding flap.
12. The unitized package of claim 11 , wherein the base card comprises one or more locking tabs under which the folding flap may be inserted.
13. The unitized package of claim 9 , wherein the fluid vessel further comprises a planar extension tab formed by the first and second laminate barrier layers, wherein the planar extension tab encloses the dispensing tip and overlays the opening strip.
14. The unitized package of claim 8 , wherein the dispensing tip is reclosable.
15. The unitized package of claim 1 , wherein the base card is less flexible than the first laminate barrier layer.
16. The unitized package of claim 1 , wherein the base card comprises a paper stock.
