[0038] In embodiments, the extensions 109 and the corner flange portions 653, 655, 657, 659 can be moved into an overlapping relationship. For example, as shown in
[0039] In embodiments, the flange features and/or other features of the blanks 3, 403, 603 and the cartons formed therefrom can help increase the rigidity of the flange and can help prevent the flange from lifting upwardly (e.g., during packing of the container and/or within the supply chain). This can assist in keeping the flange flat during sealing processes (e.g., attaching a liner and/or attaching a lid material to the flange).
[0040] Any of the features of the various embodiments of the disclosure can be combined with, replaced by, or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure.
[0041] All dimensional information presented herein is intended to be illustrative of certain aspects, features, etc., of various embodiments of the disclosure, and is not intended to limit the scope of the disclosure. The dimensions of the blanks, containers, forming tools, features, or any other dimension, can be more or less than what is shown and described in this disclosure without departing from the scope of this disclosure and can be within the listed ranges of dimensions for each feature or outside the listed ranges of dimensions for each feature without departing from the scope of this disclosure.
[0042] The blanks according to the present invention can be, for example, formed from coated paperboard and similar materials. For example, the interior and/or exterior sides of the blanks can be coated with a clay coating. The clay coating may then be printed over with product, advertising, price coding, and other information or images. The blanks may then be coated with a varnish to protect any information printed on the blanks. The blanks may also be coated with, for example, a moisture barrier layer, on either or both sides of the blanks.
[0043] In general, the blanks may be constructed from paperboard having a caliper so that it is heavier and more rigid than ordinary paper. The blank can also be constructed of other materials, such as cardboard, or any other material having properties suitable for enabling the carton to function at least generally as described above. The blanks can be coated with, for example, a clay coating. The clay coating may then be printed over with product, advertising, and other information or images.
