PACKAGE Filed Aug. 8, 1961.
2 SheetsSheet 2 INVENTOR Char/es H. 721/,0/0
ATTORNEY face of the narrow end wall 4 of the blank is overlapped by the glue flap 5. Prior to sealing of glue flap 5 to end wall 4, the longitudinal raw edge of the glue flap 5 is sealed in a suitable manner, such as by applying a sealing material such as wax, poly vinylidene chloride, or other suitable sealing materials; or the raw edge may be sealed simply by folding it over such that the edge is not exposed to the interior of the package. Thus, wickage through the porous raw edge of what is known as the manufacturers joint is prevented.
To insure against grease wickage at the joint formed by the two end raw edges of the glue flap 5, and closed flap 12, the end raw edges of the glue flap 5 are cut at right-angles to the longitudinal raw edge thereof. Thus, when a flap 12 is in closed position, its cooperating rectangular sealing sheet positively engages and entirely covers the two end raw edges of the glue flap 5, thereby preventing grease wiokage through said edges.
After the carton has been appropriately filled, the rear wall flap 12 is folded downwardly into position. In so doing, the projecting edge strips 20a, 20b and 20c of the rectangular sheet of thin and flexible material 20 are forced upwardly by contact with the adjacent portions of the inner surfaces of the carton and, of course, with the fiber tufts 18a which are formed at the tear corners due to the foreshortening, as at 18, of the cuts which separate the various flaps and tabs. The fourth and inner projecting edge strip 20d will fold upon itself and, along with the remainder of the rectangular sealing sheet 20, underlie the flap 12. The teachings of the present invention also contemplate the adhering of the two corners of the inner projecting edge strip 20d to the adjacent corners of the foreshortened tabs 14.
In the sealing of the end closure of the package, the foreshortened tabs 14 of the end walls 2 and 4 are folded downwardly onto the upper (and outer) surface of the rear wall flap 12, thus forcing the projecting edge strips Ztia and 200 to fold downwardly onto the latter. With the foreshortened tabs 14 in downwardly folded position, their adhesive strips and 26 (now extending crosswise of the carton) become effective to hold in position the rear wall flap 12 and the rectangular sheet of thin and flexible material which it carries.
Then, the front wall flap 16 is folded downwardly onto the previously folded elements, thus providing total edge contact with the right-angular corners of the glue flap 5 and again scaling up the raw edge of a lap joint. In such position, its inner and outer adhesive strips 25 and 26, respectively, come into coextensive contact with the immediately underlying portions of the package. It will also be observed that the undercutting or profiling of the outer side edges 14a of the foreshortened end wall tabs 14 enables the intermediate adhesive strip 27 to make direct contact throughout its length with the mid-section of the rear wall flap 12, except for the portions of the folded edge strips 20a and 20b which overlie the said flap.
Pressure is applied in conventional manner to complete the seal.
It will be understood that, as in the case of my copending patent application Serial No. 851,183, the gluing pattern disclosed herein is illustrative only.
When the various flaps and tabs are folded in the sequence described, the overlapping edges 20a, 29b and 200 of the sheet 2&) become firmly adhered to those portions of the carton with which they come in contact. Like- Wise, the ends or corners of the inner overlapping edge or strip 20d.
It is preferable that both ends of the package of the present invention embody the elements described herein and claimed hereinafter. However, it is contemplated that, under certain conditions, one of the ends of the package maybe closed by other effective means.
While I have shown and described certain specific embodiments of the present invention, it will be readily understood by those skilled in the art that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of the invention as defined in the appended claims.
I claim:
