PACKAGE Filed Aug. 5, 1943 mwm f A foy-117 Pf?. JO/e// Patented Oct. 31, 1944 y UNITED STATES PATENT ori-fica Pacman Jaim P. a. scheu, Barnesville, application August s, im, sensi Nu. msec 'somma 'I'his invention relates to an imrovedf'pacb' age. .l

V In my application Serial No. 380,571, iiled February 26, 1941, which has matured into Patent No. 2,361,876, I have described an improved type of package which is-preferably collapsible and which includes an outer carton andan'inner flexible liner which may or may not -be'attached to the carton. A portion of the liner extends between lips formed by ilaps lon the carton, and by puncturing thisy portion of the liner, a spout is formed through which the'contents of the package may be dischargedV by applying pressure, which collapses the package.' The inner liner is preferably formed from al single oblong sheet of mapping material, preferably rubber hydrochloride film or` vother moistureprooi,

Y liquid-tight material, which is folded in half and,

sealed along each edge adjacent the fold t form an envelope. This envelope may be squared up to form the liner for the carton, and then alter iilling the package, the top of the envelope may age, and by cutting the point @me oms suitabi opening is formed forvthe discharge ofthe contents of the package. The package is designed particularly for the sale of such materials as mayonnaise, mustard, peanut butter, etc., which are consumed a little at a time and should be protected fromA the air and evaporation during the intervals between use.

In the present improved form'of the inven- I tion, the front and back'wall of the carton are collapsed toward one another, and the sidewalls are scored so that they collapse inwardly. The liner extends between theflap on the back wall and that portion of the ap on the front wall whichA forms an extensionl beyond the length of flap required to cover the top of th carton. The preferred form of package isconstructed to be `self-sealing byproviding means fortemporarily fastening the ap on the back wall to the ilap of the front wall 'which covers the top of the carton.

'I'he invention will be further described in connection with theaccompanying drawing, in which Fig. 1 is a plan view of the blank oi' chip board or other suitablefilber material from which the carton is formed, Fig. 2 shows'the carton with vthe opening closed, and Fig. 3 is a view similar to m. 2 but with the flap on the back wan of the carton extended.

. The 'carton comprises the front 2 an jthe side walls! and 4. B sho 4 in forming the carton. The manner oi' scoring the blank is clearly shown in Fig. 1, the sdouble lines indicating scorings on the inner surface o! the blank and the dotted double lines indicatinmscoringsl on the outer surfaceof the blank.

It will be I and the back There is a lip noted from Fig. 1 that the top and in Fig. 1, which is glued t0 the side Wall bottom edges of the side walls are not parallel v but that each forms a wide V. This causes the package to appear somewhat collapsed when ilrst formed and before the sides have been pushed in. A package which is thus formed may'be collapsed more readily than one in which the top and bottom edges of the side walls are perfectly parallel.

The iiaps on vthe top and bottom of the side walls are not square cornered but together taper away from the walls so that the package may be more easily collapsed. In the preferred form there are two separate -fiaps at the top and bottom oi' each side wall, as, shown in Fig. 1.

The naps 6 and 1 on the bottom of the front and back wall may be oi! any usual design. Il the flap on the back wall is to be folded over the ilap on the front wall, the front ap preferably covers no, more thanhalf of the bottom of the package, and th'e ilapon the back may ad- `vantageously cover the whole of the bottoni, but, in this case, it is preferably scored down the middle so that the package may be easily eolf 40 lapsed. This arrangement is illustrated in the drawing.

The ilap, at the top of the front wall is composed of three, portions, III, II, and I2. The por.-

tions I0 and Il each cover one-half oi the top lof the carton, and these are divided by the scored line i3. n'I'he portion I5 of the -flap forms an extension which extendslbeyond the top of the carton and cooperates with the iiap on the back oi' the carton, and together witha portion 50, I6 of the liner which extends between them,'they form a spout for the discharge of the contents of the package.

A 'I'he flap at the top of the back vof the carton is composed of four portions, I1, I8, I9, and 20.

The portions "I 1- and I8 are divided by a scored vthe'i'ront and back walls.

line 22, which permits the portions I8-20 to be folded away from the portion I1, and the portions I2 and I1 form a spout between which the portion I6 of the liner extends. The portions I2 and Il of the front and back flaps may be glued together.

After a portion of the contents of the package has been removed and it is desired to close the carton, the nap I1-20 is folded down over the top of the carton,\and this folds the extension I2 back on the portion II of the front flap. The portion I9-20 is now slipped into the opening 25 in the front flap. The side edges of this opening are tapered toward the back of the carton, and the side edges of the portion I9 of the flap are tapered toward theback of the carton so that the portion I9 may be easily slipped into the opening 25; because of the tapered edges of the opening and the portion I9, the back iiap is held firmly in the opening v25. This forms a sharp bend along the top edge of the back wall of the carton which presses the walls of the portion" of the liner together Aandl excludes theV air from the package. f

'I'he closure thus formed may easily be broken by applying pressure along the line 22 of the back flap. When the catch portion of the back flap is fitted into the opening 25 of the front flap, the wide edge formed at the fold 26 does not coincide exactly with the fold I3 across the top of the front ap. This is shown in Fig. 2. This causes the fold 22 to bend outwardly somewhat, and the l gradually collapse the carton, and between back flap is raised somewhat from the topof the carton at this bend. By,applying pressurel directly at Athe bend to flatten the fold 22, the back flap is flattened and thus lengthened sumciently to force the front edge 26 of the catch into the wide front portion of the opening 25, and this quickly releases the catch. l

The carton may be assembled in any usual way. The liner may be illled before it is inserted in the carton; or, as is preferable, it lwill be filled whilev within the open carton, and the four bottom flaps will be folded in by first folding in the flaps on the side walls and then the flaps 6 on the front wall and then the flap 'I on the back wall, there being adhesive on the portion of the flap I which overlaps the flap 6. After the package is filled, the top of the carton will be closed by heat-sealing the carton; and in the preferredform of the invention, the seal is made as above-described, and two triangular ears are formed at-each en'd of the top oi the liner. These ears extend beyond The ear extending beyond the front/wall is folded in in the usual manner, either above or-below the flaps on the periods oi use the carton is closed by folding the back flap over and catching the portion I9 in the opening 25.

The carton is so constructed that asit is collapsed, the front and back walls remain parallel to one another, and the package will stand upright at all times until it has been emptied. The side walls are scored so that they collapse inwardly as pressure is applied, and the aps on the top and bottom of the side walls are so designed as not to hinder the collapsing of the carton or the insertion of the catch I9-2Il through the opening 25. v

What I claim is:

1. In a package formed of a bag linerr and an outer carton closed at the top by a flap on the front of the carton which extends beyond the top of the carton when folded over and forms with the flap on the back of the carton an opening at the top edge of the back of the carton through which a portion of the liner protrudes, the improvement which comprises side walls, the top and bottom of which are notched by'wide V-s which extend from the corners tothe center thereof, the two side walls and the top and bottom of the package being scored so that the package may readily be-collapsed with the front and back of the package being maintained in substantially parallel planes throughout the collapsing thereof and with indiyidual flaps at the top and bottom of each half of each side Wall. the edges of said flaps adjacent the front and back of the carton being tapered away from the side wall so thatthe package may be collapsed to a, considerable extent before the edges ofthe flaps on the side walls contact the front and back of the package. y

2. In a package formed of a bag liner and an outer carton closed at the top by a flap on the front of the carton which extends beyond the top which a portion of the liner protrudes, the improvement which comprises an opening in the flap on the front of the carton into which a portion of the ap on the back of the carton is side walls. The front wail is then folded over,

and the portions III and II are glued to the flaps on the side walls. The extension I2 on the front ilap is inA this way brought flat against the por-.

tion I'I of the back flap with the triangular ear protruding between them. Preferably, theedges of the extension I2 and the flap I1 will be glued together. The .back flap will then be folded down and the portion4 I caught in the opening 2 5. If preferred, the back flap may be folded fiat against the outer surface of the top flap'. and the portion 20 glued on to the exposed surface of the portion I0 of the front flap.

When the package is to be used, it is opened as shown in Fig. 3, and the point of the inner liner I 8 is snipped ofi', or the liner is punctured in any suitable manner to allow the contents 'to escape. Then, as thel contents are desired, pressure is applied to the front' and back wallsito adapted to fit so as to close the package and fold the front and back flaps sharply at the edge along the top of the back of the carton.

3. In a package formed of a bag liner and an outer carton closed at the top by a flap on the front of the carton whichextends beyond the top of the carton when folded over and forms with the flap on the back of the carton an opening at the top edge of theback of the carton through which a portion of the liner protrudes, the -improvement which comprises side walls which are notched by straight lines extending from the corners to the middle thereof.
