This invention relates generally to the art of packaging and more particularly to an improved low cost but attractive packaging device and the methods of making the same.
In the packaging arts, a need is constantly present for new and useful packaging devices which lare attractive, useful and yet inexpensive to produce. In this art, such devices also obtain additional consumer appeal if the original packaging devices can ,provide other uses in and about the home or oice .after the original function of the package has been fullled.
It is, accordingly, a primary object of the present 1nvention to provide an attractive versatile low cost packaging device and methods of making the same.
It is a further object of the present invention to provide an improved package device which utilizes inexpensive materials for its production.
It is still another object of the present invention to provide an improved packaging device which comprises containing means having an integrally formed cover member in coaction therewith to provide a base, hinge and enclosure for the device.
Still another object of the present invention is the provision of a novel packaging device in which plastic materials are used in unique coaction with one :another to provide a durable lightweight construction.
A still further object of the present invention is to provide a novel packaging device which is adaptable to a myriad of secondary uses once its initial use has been fulfilled.
These :and still further objects, as shall hereinafter appear, are readily fulfilled by the present invention in a remarkable unexpected fashion as can be readily discerned from the following detailed description of the illustrative embodiment of the invention, especially when read in conjunction with the accompanying drawing in which:
FIG. 1 is an isometric showing of a packaging device embodying the present invention with the lcover member in an open position;
FIG. 2 is an isometric showing of a packaging `device embodying the present invention with the cover member in a closed position;
FIG. 3 is a plan view of a packaging device of FIG. 1;
FIG. 4 is a cross section taken along lines 4 4 of FIG. 3 and looking in the direction of the arrows; and
FIG. 5 is a plan view of the insert member used in this invention.
Referring to FIG. 1, the general reference is used to identify the packaging device of this invention which, as shown, comprises a container member 12 and, in novel coaction therewith as shall be hereinafter described, a cover member 14.
Container member 12 is preferably constructed to pr-ovide one or more containing areas 16 each open at its top, enclosed laterally by side walls 18, and enclosed at its bottom .by bottom wall 20. Where, as in FIG. 1, a plurality of containing areas 16a, 16b, 16e, 16d, are desired, the external side walls 18 may be of integral construction and the internal side walls 22 may be integrally molded therewith or formed as a cross-shaped insert, as desired. Externally, side walls are provided with an outwardly extending flange 24, the function of which will be described hereinafter.
Cover member 14 comprises a first sheet 26 and a second sheet 28 integrally bonded to said first sheet 26 and having an insert member 30 operatively interposed therebetween as shown in FIGS. 3 and 4.
In practice, sheet 26 is longer than sheet 28 as will, for descriptive purposes, be referred to as a full sheet while sheet 28, while of substantially identical width, will, because of its lesser length, be referred to as a partial sheet.
Insert member 30 is specially designed to comprise a rst end portion 32, a second end portion 34 and an intermediate portion 36. In dening insert member 30, end portions 32 and 34 will be of substantially identical dimensions while intermediate portion 36 is distinguishably smaller. End portions 32, 34 will be partially separated from intermediate portion by slots 38, 4t), respectively, cut therebetween to provide upper ligaments 42, 44 and lower ligaments V46, 43, respectively. The unique value of this arrangement will become apparent in the description that follows.
To construct `cover member 14, sheet 26 is laid flat and insert member 3) is laid thereupon. Member 30 is c-ut to conform to sheet 26 in general shape although slightly smalled in size, that is, sheet 26 will extend beyond member 30 about 1/16 of an inch on all edges to provide borders Sii. Next, sheet 28 is registered with one end 52 of sheet 26 and covers end portion 32 and intermediate portion 36 of member 30 while leaving end portion 34 uncovered.
With these members thus arranged, a heat seal is effected in a conventional manner to bond border Sti to the corresponding portion of sheet 28 and to bond sheets 26 and 28 to each other through slots 38 and 4t?. When so sealed, sheet 28 has a flap 54 adjacent slot 40 whose function will be explained.
Thus formed, cover member 14 presents `a lid portion 56, a hinge portion 58, and a base portion 60.
In preferred practice of this invention, sheets 26 and 28 will be formed of a suitable heat scalable plastic material such, for example, as vinyl acetate polymers, vinyl chloride polymers, vinyl chloride-acetate copolymers and the like while insert member 30 will be formed of cardboard, stiffened paper, or other suitable relatively inflexible material having sutlicient properties to withstand the repeated bending which ligaments 42, 44, 46, 48 will be subjected to in use.
Container member 12, which for illustrative purposes wl be considered as having four compartments, although it is understood that it can have any desired number, that is, one or more, is preferably formed of a suitable material such as lightweight but tough plastic polystyrene, cellulose, cellulose-acetate, certain of the acrylics, polyamides, and the like, which is readily formed on plasticforming equipment, such as presses, injection molding machines and the like, and can be heat sealed. Preferably, member 12 is made of so-called hollow construction, see FIG. 4, as this represents the most economical use of material. In another practice, member 12 may be created by forming a sheet of suitable plastic about an appropriate form to provide internal walls 22, bottom 20, and external side walls 18, each having an outwardly extending flange 24. In iinal assembly, the flanges 24 of container member 12 are arranged in registry with the border Sti on three sides of base portion 60 while ange 24 adjacent flap 54 is tucked thereunder. Then, suitable bonding is effected, such, for example, as heat sealing, or like conventional methods, whereupon cover member 14 and container member 12 are integrally joined to provide a unique packaging device. In joining container member 12 to cover member 14, R.F. induction heating is a particularly satisfactory method for it effects the desired fusion without adversely affecting any of the surrounding portions of the thermosetting compartment of the thermoplastic cover.
In a preferred practice of the invention, a precut full sheet of calendered vinyl plastic is laid out on Ka work surface and overlaid with an appropriately dimensioned, selectively slotted card-board insert to provide a small border of vinyl thereabout. Next, an appropriately dimensioned partial sheet of calendered vinyl plastic is placed on the cardboard in register with one end of the full sheet leaving a base portion of cardboard exposed. The container member, formed as indicated, is located on this base portion so that three outwardly reaching sidewall fianges coincide with the exposed portion of the border of the first sheet. The entire arrangement is then subjected to a sealing action peripherally of the full sheet and transversely of this sheet through the slots in the cardboard liner. These later welds coact to define hinges about which the containing members and the cover portions pivot to permit opening and closing of the packaging device through at least 180 or more.
Thus practiced, a unique attractive low cost packaging device is created which not only functions efficiently as a point-of-sale packaging device but which further possesses the desirable attribute of a myriad of secondary uses, both in the home and ofiice.
Further, from the foregoing, it becomes readily apparent that a new and improved packaging device has been herein described yand illustrated which fulfills all of the aforestated objectives in a remarkably unexpected manner.
it is, of course, understood that the embodiments and illustrations herein described are done so by way of illustration only and that such applications, modifications, alterations as may readily occur to the artisan confronted with this disclosure are intended within the spirit of this invention, especially as it is defined by the scope of the claims appended hereto.
