A mailer package is formed from a single sheet of foldable stock material and includes a pair of major planar parallel panels adjoining one another and joined together along a first fold of the material. A pair of panel tabs extending from opposing edges of one panel of the pair and are secured to opposing edge portions of the remaining panel of the pair. A closure flap extends from a fourth edge of the one panel and overlaps the remaining side of the package when closed, extending between the pair of panel tabs. The closure flap abuts the panel tab when the closure flap is closed with only pull tabs at the lateral sides of the closure flap extending above the panel tabs and the remainder of the closure flap. The closure flap extends more than halfway from the closure flap fold to the opposing first fold such that the pair of panel tabs and closure flap cover more than half of a major side of the closed mailer package.

CARDBOARD MAILER PACKAGES
This application is a continuation of application Ser. No. 08/068,464, filed May 27, 1993, now abandoned.
FIELD OF THE INVENTION
The present invention relates to packaging and, in particular, to cardboard type mailer packaging.
BACKGROUND OF THE INVENTION
Certain items such as photographs, drawings and floppy disks, which may be extremely valuable, are ordinarily sent through the mails and through private courier services despite the fact that bending or wrinkling of such items through inadequate package protection may ruin or at least greatly decrease the value of such items.
A number of different cardboard mailer designs have been used or proposed. While most provide some increased stiffness over conventional paper and plastic type envelopes, they still provide only a marginal or slight improvement against bending and folding over the protection provided by stiff paper envelopes.
Some items which are customarily mailed require still greater protection. For example, floppy disks with exposed data storage surfaces need protection from contact with abrasive surfaces within the mailer. Both paper and cardboard have surfaces which are sufficiently abrasive to pose a potential threat to the surface of any floppy disks coming into contact with such surfaces.
The only mailers currently known for protecting floppy disks from abrasion are formed of folded cardboard in a conventional fashion and provided with a separate, loose, folded foam plastic liner. The foam liners are made separately from the cardboard mailers and inserted into the mailers by the manufacturer. The number of different items being fabricated and the number of steps needed for assembly increase the cost of such mailers greatly over the cost of corresponding mailers without the foam liners, even when taking the material costs of the foam into consideration. Also, the foam material utilized is as thick or thicker than the cardboard, greatly increasing the bulk of the packaging. At the same time, the foam material provides no additional rigidity or structural strength. Typically, the foam liner material is treated with an anti-static agent to further protect the floppy disk.
SUMMARY OF THE INVENTION
The present invention is a mailer package formed from a single sheet of foldable stock material comprising: a pair of major, planar, parallel panels overlying one another and joined together along a first fold in the material, the first fold defining at least part of a first of four edges of the mailer package; a pair of panel tabs extending from opposing edges of one panel of the pair of panels, the pair of panel tabs overlapping and being secured to opposing edge portions of a remaining panel of the pair of panels; second and third folds connecting the pair of panel tabs with the opposing edges of the one panel, the second and third folds defining at least parts of second and third edges of the mailer package; and a closure flap extending from a fourth edge of the one panel, the closure flap including at least a pair of lines of perforations therethrough, the lines of perforations extending generally parallel to one another and to a fourth
fold joining the closure flap and a fourth edge of the one panel, the closure flap between the lines of perforations protruding laterally from a remainder of the flap to define at least one pull tab, and a remainder of the closure flap being sized and shaped to fit between the pair of panel tabs when the sheet of material is folded along the fourth fold and on to the remaining panel with only each pull tab defined between the lines of perforations overlapping either of the pair of panel tabs.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF PREFERRED
FIG. 1 depicts a preferred mailer package blank indicated generally at 10. The blank 10 is preferably formed by a single sheet of foldable material of uniform thickness and composition. Various parts of the blank are defined by fold lines or lines of perforations. A pair of major, planar, parallel, rectangular panels 12 and 20 form a major portion of the blank 10. A first fold line 13 defines a first edge of each of the pair of panels 12 and 20 and simultaneously connects those panels 12 and 20 together at their first edges. A pair of panel tabs, 22 and 24 respectively, extend from opposing second and third edges of one panel 20. Fold lines 21 and 23, respectively, between the one panel 20 and each of the respective tabs 22 and 24, define the second and third edges, respectively, of the one panel 20. Second and third fold lines 21 and 23 extend generally parallel to one another and generally perpendicular to the first fold line 13 and from that first fold line 13 generally to a fourth fold line 25. The fourth fold line 25, which defines a fourth edge of the one panel, is generally parallel to the first fold line 13 and perpendicular to the second and third fold lines 21 and 23 and extends between the ends of those lines 21 and 23 which are most remote from the first fold line 12. A closure flap indicated generally at 30 extends from and is coupled with the fourth edge of the one panel 20 along fold line 25.
Preferably, the closure flap 30 is provided with a pair of lines of perforations 31 and 32, which extend through the flap 30 and are at least generally parallel to one another and to the fourth fold line 25. Preferably, the closure flap 30 between the lines of perforations 31 and 32 protrudes
