Abstract
A flexible container, and a process and apparatus for making the container having first and second sidewalls, side seams, a bottom edge, a top and an opening adjacent the top including the first and second sidewalls made from the same film web stock material, said web stock having at least a first visual pattern impressed thereon such that upon forming said first and second sidewalls from said web stock, said first and second sidewalls are adjacent to each other and at least a second visual pattern on the container different from the first visual pattern is perceived by an observer of the container.
Claims15
A container comprising a single clear film web sheet having a fold therein, said folded sheet having a bottom at said fold, a first sidewall and second sidewall, side seams and an open top defining a container, wherein the sheet has a first visual pattern scored or impressed into said film sheet such that the same said first visual pattern is on the first sidewall and the second sidewall, said first sidewall and second sidewall being adjacent to each other, thereby bringing the first visual pattern on the first sidewall in juxtaposition with the first visual pattern on the second sidewall in a non-mirror image configuration, whereby the container has a distinct second visual pattern different from the first visual pattern visible through each of the sidewalls of the containers.
A container comprising first and second sidewalls side seams, a bottom edge, a top, an opening adjacent the top and opposing interlocking profiles attached to said first and second sidewalls adjacent the top opening said first and second sidewalls formed from a single film web sheet folded onto itself,
- the first sidewall with a first visual pattern scored or impressed into said sidewall and the second sidewall with a visual pattern substantially identical to the first scored or impressed pattern such that when the two sidewalls are brought into substantial contact with each other or adjacent each other a different second visual pattern is created.
A reclosable plastic container formed from a single film web sheet comprising
- a front sidewall and a back sidewall with side seams, a bottom and a top with interlocking fasteners,
- said front and back sidewalls containing scored or impressed markings forming at least a first initial visual pattern such that when the front and back sidewalls are adjacent each other and such that when an intervening substantially nontransparent material is placed between the sidewalls and the front and back sidewalls are separated by the intervening substantially nontransparent material the existing first pattern on the sidewalls is visually formed, and such that when an intervening substantially nontransparent material is not placed between the sidewalls and the front and back sidewalls are not separated by the intervening substantially nontransparent material at least a second visual pattern different from the first visual pattern is visually formed, thereby providing an indication of when the container is loaded or unloaded.
