BUTTON PACKAGE Filed Feb. 9, 1966 II JVENTOR. CHARLES SCHNER JIII I40 BY ATTORNEYS United States Patent York Filed Feb. 9, 1966, Ser. No. 526,143 8 Claims. (Cl. 206-78) The present invention relates to the packaging of buttons and the like and, more particularly, to a new and improved display package in which a plurality of buttons having shanks, hooks, eyes, or like projections may be completely enclosed in an attractive manner.

It is an object of the present invention to provide an inexpensive, two-walled package for buttons which completely encloses the same and which may be expeditiously and simply opened by tearing through the packaging material itself.

A further object of the invention is to provide a button package which has a substantially long shelf life and which may be employed with disklike buttons of varying sizes and configurations.

Another object of the invention is to provide a heatsealable button package of the type described which maintains the top and bottom walls in intimate overall physical contact without being sealed in overall faceto-face contact.

These and other objects of the invention have been realized in a new and improved package having a planar, transparent front wall against which a plurality of buttons are held by an opaque or translucent, molded rear wall, having a plurality of stepped cylindrical cavities.

For a more complete understanding of the invention and its attendant advantages, reference should be made to the following detailed description taken in conjunction with the accompanying drawing, in which:

FIG. 1 is an exploded, perspective view of the components of the package of the invention;

FIG. 2 is a perspective view of an assembled button package embodying the principles of the invention; and

FIG. 3 is a fragmentary, cross-sectional view taken along line 33 of FIG. 2 showing details of construction of the package of the invention.

As shown in FIG. 1, the new and improved package is made from two elements, a front sheet made from a planar, transparent, heat-scalable and readily tearable material, and an opposing, pre-molded tray 11 made from a non-transparent, heat-scalable and readily tearable material. A group of buttons 12, each of which has a front face 13 and a rear face 14 from which an appurtenance 14a extends, is disposed and retained between the front and

rear elements

10, 11 in a manner to be more fully described. As will be understood, the new package may be used with equal facility with buttons having holes therein in lieu of appurtenances such as hooks, shanks, eyes, and the like.

Specifically, the rear element 11 is generally rectangular and is formed with a plurality of stepped cavities 15 equal in number to the quantity of buttons (six in the illustrated embodiment) to be included in a single package. Each of the cavities has a button supporting shoulder 16 which is defined by a step between the outer walls 17 thereof which define a large button-receiving recess 18 and a smaller appurtenance-receiving recess 19. In the illustrated preferred embodiment the

recesses

18, 19 are generally annular, although being slightly tapered in their cross section to facilitate their formation by conventional molding processes, but recesses of other shapes may be employed for odd-shaped buttons and the like, as should be understood.

3,3 l8,445 Patented May 9, 1967 In a typical package, the rearmost recess 19 of a cavity 15 will be approximately inch in diameter and will have a depth of approximately inch. The larger recess 18 may have any diameter greater than that of the buttons being packaged and usually has a depth of approximately 1 inch. As an important aspect of the invention, the rear elements will be able to accommodate a large number of different button sizes ranging between diameters slightly in excess of the small recess and diameters slightly less than the large recess. Moreover, a variety of sizes and types of buttons may be packaged in a single tray, as should be understood.

In accordance with the principles of the invention, cavities are formed in the rear element 11 in regions spaced inwardly (approximately inch) from the side and bottom edges and spaced further inwardly from the top edge to provide circumferential frame-forming margins 20. In a typical arrangement such as illustrated in FIG. 1, the topmost row of cavities 15 is spaced approximately 7 inch from the top edge to provide a wide enough margin to define an opaque or translucent contrasting field 22 for any advertising or identifying legend 23 that may be carried by the transparent and planar front sheet 10. Furthermore, and for purposes of enhanced display, the rear element is of a predetermined hue which contrasts with the hue of the buttons being packaged. Thus, when lightly colored or white buttons are to be packaged, a contrastingly hued rear element (blue, for example) is employed. Conversely, if colored buttons are to be packaged, a white tray may be used to advantage.

In the preferred embodiment the tray 11 is pre-molded from sheets or webs of expandable polystyrene foam having a thickness of 40 mils and a sufliciently low density, e.g., 7 pounds per cubic foot, to provide a relatively rigid, relatively non-stretchable button support which may be torn (although not punctured) with ease. As will be understood, the elements 11 may be mass produced on large sheets or webs, which may subsequently be cut down to a predetermined finished size, for example, 3 X 5 /2 inches as in the illustrated package.

In accordance with the invention, the front sheet 10 is transparent and of a similiar shape and size to that of the tray 11. In addition to being transparent, the front sheet must be relatively free of moisture, in order not to 'deleteriously effect the material from which the buttons are manufactured, and it must be relatively punctureproof in order to withstand rough handling by consumers when the packages are marketed in rummaging bins rather than on display racks. The front sheet 19 also must be heat scalable to and compatible with the tray 11. Furthermore and similarly to the rear element 11, the front sheet must be capable of being easily torn in the subsequent opening of the package by the consumer. It has been found that a most suitable material for use as the front element 10 of the new package is a sheet of extruded, bi-axially oriented polystyrene having a thickness of 5 mils.

Formation of the new package is quite simple and may be carried out With conventional apparatus and with minimum expense. Specifically, the buttons 12 are placed into the cavities 15 with their'rear faces 14 resting on the shoulders 16 and with their hooks 14a projecting into the recesses 19. Thereafter, the sheet 10, which advantageously carries an appropriate identifying legend 23 at its upper edge, is aligned with the tray 11 in a manner in which the field portions 22 of the tray underlie the legend 23, as shown clearly in FIG. 1. With the components of the package thus aligned, they are heat sealed together at temperatures of 400-450 F. and pressures of 70l00 p.s.i., along predetermined spaced peripheral and central 7 Furthermore, the package may bands 24 and 25 of /s-inch width. As shown in FIG. 2, the heat seal pattern provides unsealed, tear-opening zones 26 and secures the front sheet 10 to the rear sheet 11 in a manner which precludes escape of the buttons from the cavities in which they are placed. Moreover, the heat 7 tions, which may be readily opened by simply tearing the opposed package walls, advantageously starting the tear at one of the tear-opening zones 26. In addition the package of the invention has an especially long shelf life, the materials of the package themselves resisting deterioration, clouding, embrittlement, and the like, as well as protecting the buttons from environmenal attack.

Thus, it should be appreciated that the finished package of the invention provides a complete and high degree of protection for the buttons contained therein, as well as providing an attractive and durable display therefor. be produced simply and economically with available, conventional packaging machinery.
