Unitized package of card and fluid vessel
View Patent ↗Unitized packages for containing and dispensing a product material are described herein. 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 reclosable 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 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,
wherein the second laminate barrier layer is permanently bonded to a portion of the printed base card;
wherein the fluid-tight enclosure comprises a dispensing tip and the printed base card comprises a score line that intersects the dispensing tip, in which the score line defines a folding flap that when folded along the score line reclosably seals the dispensing tip.
2. The unitized package of claim 1 , wherein the printed base card comprises one or more locking tabs capable of receiving the folding flap.
3. The unitized package of claim 1 , wherein the thickness of the printed base card is about 0.008 inches or greater.
4. The unitized package of claim 1 , wherein the thickness of the printed base card is about 0.010 inches or greater.
5. The unitized package of claim 1 , wherein the biaxially oriented thermoplastic polymer comprises a polyethylene, a polypropylene, a polyester, a polyamide, a polyarylate, or a mixture thereof.
6. The unitized package of claim 1 , wherein the biaxially oriented thermoplastic polymer comprises a polyethylene terephthalate.
7. The unitized package of claim 1 , wherein one or both of the first and second laminate barrier layers comprise a layer of aluminum foil.
8. The unitized package of claim 7 , wherein the aluminum foil is less than about 0.001 inches in thickness.
9. The unitized package of claim 1 , wherein the product material is a liquid.
10. The unitized package of claim 1 , wherein the base card comprises an opening strip.
11. The unitized package of claim 10 , wherein the opening strip is defined by a line of perforation that intersects the dispensing tip.
12. The unitized package of claim 11 , wherein the distance between the line of perforation and the score line is about 0.25 inches or greater.
13. The unitized package of claim 1 , 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 1 , wherein the base card is less flexible than the first laminate barrier layer.
15. The unitized package of claim 1 , wherein the base card comprises a paper stock.
16. A reclosable 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 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,
wherein the second laminate barrier layer is permanently bonded to a portion of the printed base card;
wherein the fluid-tight enclosure comprises a dispensing tip and the printed base card comprises a score line that intersects the dispensing tip, in which the score line defines a folding flap that when folded along the score line reclosably seals the dispensing tip;
wherein the first laminate barrier layer has an inner surface and the second laminate barrier layer has an inner surface, and
wherein the dispensing tip is defined by a portion of the inner surface of the first laminate barrier layer and a portion of the inner surface of the second laminate layer; and
wherein the thickness of the printed base card is such that when the folding flap is folded along the score line to form a fold having a tension zone, the portions of the inner surfaces of the first and second laminate barrier layers that define the dispensing tip fall substantially outside the neutral point of the fold and in the tension zone.
17. The unitized package of claim 16 , wherein the modified dome shape of the first laminate barrier layer is resiliently sustainable when the fluid vessel is sealed.
