<p>The invention generally relates to unitized packages for containing and dispensing a product material. In particular, the unitized packages comprise a printed base card (20) and a fluid vessel (30) permanently bonded to the printed base card. The fluid vessel comprises a first laminate barrier layer (40) 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 (50). The first and second laminate barrier layers are sealed together to form a fluid-tight enclosure (60), wherein the product material (70) 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.</p> |
