Limited, Quincy,

Mass., a corporation of Massachusetts Application March 16, 1946, Serial No. 654,903 1 Claim. (Cl. 20.6-45.34)

This invention relates to a package and method of making the same.

One object of the invention is to provide a novel package constructed to display and preferably to visibly display the packaged commodity, which may be economically produced and whose construction is sufficiently rigid to withstand handling during commercial shipment and use.

A further object of the invention is to provide a novel, eflicient and economical method of producing the present novel package.

With these general objects in view, and such others as may hereinafter appear, the invention consists in the package and method of making the same, and in the various structures, arrangements and combinations'of parts hereinafter described and particularly defined in the claim at the end of this specification.

In the drawings, Figs. 1 to 4 illustrate in perspective successive steps which are preferably employed in the formation of the lined carton in a condition ready to be filled with the commodity to be packaged; Fig. 5 is a perspective illustrating the filled carton just prior to the formation of the top closure therefor; Figs. 6, 7 and 8 are details in perspective illustrating the positions occupied by the flaps and top closure during successive steps in the formation of the package; and Fig. 9 is a perspective illustrating the completed package.

In general, the present invention contemplates a novel construction of package comprising a bag rectangular in section for containing the commodity to be packaged. The bag may and preferably will be formed of any of the usual or preferred bag forming materials such as parchment paper, but preferably the bag is constructed of cellophane or other relatively strong transparent paper. The top of the bag is closed after the bag has been filled, by an elongated closure, preferably of the pull-put type, which is I folded down onto the upper surface of the bag,

providing triangular end tabs which are subsequently folded inwardly. In order to protect the bag to enable it to be satisfactorily handled during shipment without breakage, a sleeve of relatively stiffer, stronger and heavier sheet material, such for example as carton board forming material, is wrapped about the bottom, two sides and the top of the bag so as to leave the two side panels of the bag unprotected and through which the packaged commodity is visible for display purposes. The sleeve may and preferably will .be formed by an elongated strip 2 of the stifler board forming material, and as it is wrapped about the bottom and two sides of the bag, the ends of the strip are folded 111-,

wardly upon the top of the upper surface of the bag, preferably into overlapping relation and with one of the triangular end flaps of the top closure interleaved between the contacting surfaces of the overlapped portions of the strip. The overlapping ends of the strip are adhesively secured to one another providing a completed package which may be economically manufactured and handled during shipment and use exactly as an ordinary lined package. In addition, the construction of the package lends itself to convenient opening and the retention of the top closure of the bagv in such condition that it may be subsequently closed to preserve the contents of the package.

Referring now to the drawing, the successive steps -by which the present package may be produced in a condition ready to be filled are illustrated in Figs. 1 to 5. The bag is preferably f rmed y bein wrapped about a forming block In in the manner illustrated in Fig. 1, the side seam I! being overlapped upon the opposed panel and adhesively secured thereto. The bottom of the bag may and preferably will be closed by any usual or preferred type of closure, preferably by an elongated pull-out type of closure I6 with the triangular end tabs l'l, I8 folded toward one another and uponthe bottom of the bag, as illustrated in Fig. 3. The bag in this condition and while supported upon the mandrel ID, has preferably secured to it the bottom and

side forming panels

20, 22, of the strip of carton board forming material or other relatively strong sheet material, as by being spot glued, as at 33, to the bottom and opposite sides, and in the preferred method the strip is arranged to cover the side scam I 2 of the bag. Thereafter the bag with the strip may be removed from the forming block, producing the structure illustrated in Fig. 4. In this condition the opened bag with its attached strip may be filled with the commodity to be packaged, being capable of being handled in any of the standard filling machines now upon the market and which are adapted to handle rectangular cartons.

After the filling operation has been completed, provision is made for closing the top of the bag,

and for this purpose the

portions

24, 26 of thetwo sides of the strip projecting above the score line defining the top of the body of the package may be folded outwardly and the top of the bag .closed by an elongated pulled out closure 2| formed in any of the standard top closing machines now used for producing this type of a closure. The upstanding tab 29 of the closure is folded upon itself and then down upon the top of the bag, providing

triangular end tabs

30, 32 which project onto the outwardly projecting

portions

24, 26 of the strip in the position shown in Fig. 7. Preferably one projecting portion 24, of the strip is folded inwardly, folding the triangular end tab 30 of the bag over upon the top of the bag and then the second projecting portion 25 of the strip and the second end tab 32 are folded over upon the previously folded down portion 24 of the strip thus interleaving the triangular end tab between the overlapping portions of the strip and anchoring the bag to the protecting sleeve thus formed. The portions 2t, 26 of the strip, as shown in Figs. 6 and 7, are provided with adhesive II for securing the overlapped portions of the

members

24, 26 together.

From the description thus far it will be observed that the present package is attractive in appearance, and utilizes a minimum amount of the heavier carton forming board. The protecting sleeve imparts rigidity and strength to the package enabling it to successfully withstand shipment and handling. The fact that the two opposed wide side panels of the bag are uncovered by the sleeve and therefore exposed adds to the utility of the package for display purposes, as in those instances where the bag is constructed of transparent material such as cellophane the packaged commodity is clearly visible through such transparent side panels of the package.

While the illustrated package comprises the preferred embodiment of the invention, it will be understood that other forms of top closures for the bag may be utilized and that the protective sleeve may take other forms, within the scope of the following claim.

Having thus described the invention, what is claimed is:

As a new article of manufacture, a package 4 comprising a bag containing a commodity, said bag being formed to provide a closed rectangular bottom and four rectangular side walls and having its top folded to provide a top closure, said closure comprising outwardly extending flaps, and an outer sleeve of an elongated strip of a relatively heavy stiff material of substantially uniform width substantially equal to the width of certain side walls of said bag, said sleeve being of a size snugly embracing the bottom, top and two opposite of said certain side walls of the bag whereby the free edge portions of said sleeve lie substantially in the same planes as the exposed walls of said bag, said sleeve having end portions extending across the top of said bag in overlapping relationship and having one of said closure flaps interleaved between the said overlapping end portions, said overlapping end portions being adhesively secured to each other.
