PACKAGE Sept. 2, 1958 Filed June 9, 1955 "guancia INVENToR. oscAR H. HULTIN Y'S" v CMCLAZ- ATTORNEY United States` Patent PACKAGEl Oscar H. Hnltin, QuiucyMass., assignorto Pneumatic Scale Corporation, LimitedQuincy, Mass., a corporation ofMassachusetts Application .lune 9, 1955; SerialNm 5145282" 6` Claims. (Cl. 229-17) This invention relates to a package.

The invention has for anobjectto provide arnovel and improved package comprising ad carton having an inner lining and containing ilowablefsolid material andswhieli is` provided with a novel top closure having detachable portions which may be easily torn from the closure to form an outlet providing a pouring opening upon application of pressure tothe sides ofthe carton;

With this general object in view and such others` as may hereinafter appear, the invention consistsin the package hereinafter described and particularlyi defined; inthe claims at the endof this specification.`

In the drawings illustrating the preferred embodiment of the invention:

Fig. 1 is a perspective view of a lined carton for forming the present package showing the top closing flaps extended;

Fig. 2 is a perspective view of the present package in its completely closed and sealed condition;

Fig, 3 is a vertical cross sectional view of the package shown in Fig. 2; and

Fig. 4 is a perspective view of the present package with portions detached to form a pouring opening.

In general the present invention contemplates a novel and improved package comprising a lined carton wherein a portion of the lining top closure is folded with one of the carton closing flaps in a manner such that the carton closing flap and the adjacent portion of the lining closure may be detached and torn from the top closure to form an outlet providing a convenient pouring opening upon the application of pressure to the side walls of the carton.

Referring now to the drawings, the illustrated package comprises a carton having a body portion including side and

end Wall panels

12, 14 respectively provided with three top closing aps extended from and foldably connected to the body panels including

side ilaps

16, 18 and end flap 20, one of the end wall panels 14 being free of a closing flap, as shown. An inner lining or lining bag within the carton is fold-ed to provide an elongated top closure, indicated generally at 24, herein shown as being formed by folding two opposed side walls of the lining mouth portion inwardly into overlapping relation and adhesively securing the same, and simultaneously folding opposed end walls of the lining mouth portion outwardly, thus forming hollow, laterally extended

end tabs

26, 28, triangular in shape as illustrated.

ln practice the present package is preferably formed in an automatic package forming machine known in the trade as a double package maker wherein the lining blank is wrapped about a forming block to form a tube and the lining end closure is made by folding extended portions of the lining against the end of the block, as described, one of the tabs, 28, being folded in against the side of the block, the other tab, 26, remaining in its laterally extended condition, as shown. Thereafter, the carton blank is wrapped about the lining on the block, and the first folded Hap 20 may then be folded against ICC the end of the block. Thereafter, the side aps 16, 18'

may be folded in succession one on top of the other and adhesively secured together.

As herein shown, the last folded side flap 18 may be provided with a lateral extension 30 foldably connected thereto and which is adapted to be folded down against and adhesively secured to the flap-free panel 14, the tab 26 being foldeddown with the Hap 30 as shown in Fig. 2. The flap 30 is preferably secured to the panel 14 by relatively small bonding areas of adhesive, indicated at 32, to provide a frangible anchorage readily breakable to facilitate Subsequent detachment of the hap from the panel 14, and the fold line between the iiap 30 and the side flap 18 may and preferably will be weakened by providing spaced perforations or slits along the fold line, as indicated at 34, to facilitate subsequent tearing of the flap 30 from the carton when opening the same. In some instances the lining tab 26 may also be provided with a weakened line along its fold line to facilitate tearing of the same. It will be understood that the end closure, above described and herein referred to and used as the top closure in the completed package, is actually the rst formedf-end. closure, the lined package being subsequently removed from the forming block, lled upside down, and provided with the nal end closure comprising the bottom closure in the completed package.

yFrom the description thus farit will be seen that in use the tiap portion or extension 30 may be easily detached by breaking the seals at the bonding areas 32 and that thereafter the extension 30 together with the tab 26 may be torn olf the container along the fold lines thereof, thus forming an outlet comprising a slit opening along one edge of the top closure which provides a pouring opening 33 upon application of pressure to the sides of the package adjacent the ends of the slit, and through which the contents of the package may be poured, as shown in Fig. 4. Upon release of pressure against the sides of the carton, the resiliency of the carton forming material will cause it to spring back to its initial position, thus effecting reclosing of the pouring opening.

In order to facilitate bending or bowing out of the hap-free panel 14 upon application of side pressure, the panel may be provided with a longitudinal scored or weakened line 36 intermediate the sides of the carton, the lower end of the scored line terminating about half way down the length of the carton and branching out in diagonal scored lines 38, 40, as shown.

From the above description it will be seen that in the present structure of package the carton is provided with a novel top closure embodying the lining closure and the carton closing flaps wherein detachment of an exterior carton hap portion from the wall of the carton and tearing of the ap together with a portion of the lining closure forms a slit outlet along the edge of the package which may be opened to provide a pouring opening by pressure against the sides of the carton, the opening returning to its slit condition upon release of the pressure.

While the preferred embodiment of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:

1. As a new article of manufacture, a package comprising a carton having body panels provided with extensions forming the top closing aps, one panel being free of a top closing iiap, and a lining within the carton having its mouth portion folded to form an elongated closure provided with laterally extended end tabs, one of said carton closing flaps having a lateral extension adapted to be folded down and adhesively secured to said flap-free body panel in the completed package with one of said laterally extended lining tabs folded down and interleaved and en- Patented Sept. 2, 1958y tirely concealed between said panel and said folded down extension, said lining tab being free of adhesive whereby detachment of said extension from the flap-free body panel and tearing of the entire extension and the lining tab along the fold lines thereof forms an outlet providing a pouring opening upon application of pressure to the sides of the carton.

2. A new article of manufacture as delined in claim 1 wherein said folded down extension is weakened along its fold line to facilitate tearing thereof from the top closure.
