A unit set or assembly of several superimposed parts form a mailer without a stub, folded and detachable glue flaps on the top part underlying and being secured to the bottom part. A three-part mailer construction is formed wherein the intermediate part is secured to the bottom part as the adhesive on one of the flaps extends through holes provided in the bottom part. Removal of the top part therefore leaves the intermediate and bottom parts intact, or removal of the intermediate part leaves the top and bottom parts interconnected, or removal of the top and intermediate parts separates each of the parts from one another. A minimum four-part mailer construction is also provided of superimposed parts with the first part having the folded and detachable glue flaps underlying and secured to the fourth part. The third and fourth parts are provided with axially aligned holes respectively of different sizes, the smaller sized fourth part holes defining masks relative to the larger sized third part holes so that portions of the glue on the one of the flaps extend through such aligned holes. Such glue portions are thereby confined to the smaller sizes of the third part holes so as to be spaced inwardly of the margins of the larger holes. The first part may therefore be removed from the mailer while leaving the remaining parts intact, or separation of the second and fourth parts breaks the glue portions and frees the third part from the mailer while leaving the first and fourth parts interconnected, or removal of the first part together with separation of the second and third parts separates all the parts from one another. The parts of both the three- and four-part constructions may be single plies, or one of the intermediate parts thereof may be a return envelope.
A multi-part mailer construction, comprising, superimposed first, second, third and fourth parts, said third part having at least one first hole therein of a predetermined first size along one of its margins, a quantity of detachable adhesive extending between said second and fourth parts and through said hole of said third part for securing said second and fourth parts together, said adhesive extending through said first hole having a cross-sectional size which is less than said predetermined size of said first hole so as to be spaced inwardly of the marginal edge of said first hole for retaining said third part in place, said first part having glue flaps on opposing sides thereof underlying said fourth part and being secured thereto whereby said first, second and fourth parts are connected together with said third part being immobilized to form a mailer construction having open sides at other than said opposing sides, one of said flaps having said adhesive thereon, said flaps being removably secured to said first part along opposed lines of weakening, and said parts each being devoid of any tear lines which may form a stub, whereby removal of said first part leaves said second, third and fourth parts intact, or separation of said second and fourth parts effects a break of said adhesive and frees said third part from the remaining of said parts while leaving said first and fourth parts interconnected, or removal of said first part together with separation of said second and fourth parts separates each of said parts from one another.
A multi-part mailer construction, comprising, superimposed top, intermediate and bottom parts and a cover ply disposed over said top part, glue flaps detachably connected to opposite sides of said cover ply along opposed lines of weakening, said flaps underlying said bottom part and being adhesively secured thereto whereby said ply, said top and bottom parts are connected together with said intermediate part being immobilized to form a mailer construction having open sides at other than said opposite sides, first and second axially aligned holes of different sizes respectively provided in said bottom and intermediate parts, the size of said first hole being less than the size of said second hole, a portion of the glue on one of said flaps being detachable glue and extending through said aligned holes, the size difference between said holes defining a portion of said bottom part which masks said second hole so as to confine the cross-sectional size of said glue portion to the smaller size of said first hole, and said parts each being devoid of any tear line which may form a stub, whereby said cover ply may be removed from the mailer while leaving said parts intact, or separation of said top ply and said bottom part breaks said glue portion and frees said intermediate part from the mailer while leaving said cover ply and bottom part interconnected, or removal of said cover ply together with separation of said top and bottom parts separates said ply and said parts from one another.
A multi-part mailer construction, comprising superimposed top, intermediate and bottom parts, said top part having folded glue flaps detachably connected to opposite sides thereof along opposed lines of weakening, said bottom part having at least one hole therein along one of its margins, said flaps underlying said bottom part and being secured thereto whereby all said parts are connected together into a mailer construction having open sides at other than said opposite sides, the glue on one of said flaps being detachable glue and extending through said hole to thereby connect only said intermediate and bottom parts together, and said parts each being devoid of any tear lines which may form a stub, whereby removal of said top part leaves said intermediate and bottom parts intact, or removal of said intermediate part leaves said top and bottom parts interconnected, or removal of said top and intermediate parts separates each of said parts from one another.
