(cl. zza-45) Y I Claim..

My invention relates to re-closing cartons andhas for an object to provide a carton having a top normally connected to the lateral walls of the carton and adapted to be severed therefrom to provide a discharge opening in the carton and a closure for closing the same.

An object of the invention resides in providing latching means for holding said closure in closing' the neck and shouldersat the.end of the cut-out nearest the edge of the lateral wall to which the closure is connected and in forming the eye in the portion of the cut-out farthest from said edge.

Another object of the invention resides in the specific form and construction of the tab and aperture with which the same cooperates.

the blank outwardly of the scores |5 and IS are sheared alongV lines 22 and 23, which lines lie in continuation of the scores |2, |3 and |4, and divide the marginal portions of the blank into end flaps 24, 25, 25 and 21 at the upper end of the carton, and similar fiaps'28, 29, 3| and 32 at the lower portion of the blank. In addition, the

corners of the blank are cut away between the scores |5 and and the scores and IB. as designated at 33, 'to leave a marginal portion 34 on the blank which forms a glue fiap by means of which the wall |'l may be connected to the wall 2| in the customary manner.

For the purpose of the invention the 24 and 25 are provided with transverse scores 31 and 38 which extend Ifrom the outer edges of the said fiaps up to the score |5. In addition,

' the carton is perforated along the portions of the score line |5, indicated by the reference numerals 35 and 35. 'These perforations ex-tend from Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the drawine:

Fig. 1 is a developed view of a blank from which a carton constructed in accordance with my invention is formed.

Fig. 2 is a perspective view of a closed carton constructed from the blank shown in Fig. 1.

Fig. 3 is an elevational sectional view taken on line :1-3 o: Fig. 2.

Fig. 4 is a perspective view of the carton with the scores 31 and 38 past the lines 22 and fall short of one another to 'leave a scored portion 38 between the flap 26 and the endwall -|9 which will be subsequently more fully described.

In the walLlS of the blank is formed a cutout 4| which terminates at the junctures between the perforations 35 and- 35 and the score 39. This cut-out is arranged to form a tab 42 severable from the end wall IB, and when severed leaves an aperture 43 in the said end wall, as clearly .shown in Fig. 4.

The carton is erec'ted'and fliled in the usual manner. In erection the iiaps 24, 25,' 26 an'd 21 I erected carton'is indicated by the reference charthe portion of the top forming the closure severed v from the lateral walls of the carton and Illustrating the closure in open position.

Fig. 5 is a view similar to Flg. 3 showing the closure in re-closed position.

'My improved carton is constructed from a blank shown in Fig. 1 which is indicated in its entirety isformed from paper board or any other suitable material from which cartons are usually constructed and is formed with four spaced parallel scores |2, |3 and |4, and with two iongitudinally extending scores |5 and IG. These scoresl divide the blank into two lateral side walls" |1 and IB, and two fateral end walls |9 and 2|.

acter 20 in the drawings. The two scores 31 and 38 in the flaps 24 and 25 are so arranged in the blank that said scores are disposed in overlying position so that, when the top of the carton is severed ,along the perforations 35 and 35 and the cut-out 4|, a closure is formed which is hinzedly connected to the remainder of the top 44 along said scores 31 and 38. When the closure 45 is severed from the carton, the upper edge 41 of the wall I! becomes free and similarly the outer edge 48 of the closure 45 becomes free.

The cut-out 4| is so constructed that the tab 42 is providedwith a neck 43 at the lccality of the issuance of the same from the free edge 43 of the closure 45, and so that shouiders 49 are formed The portions of 35 adJacent said`v neck which have surfaces 5| diverging outwardlyvfrom said neck. The cut-out 4| is alsof. constructed so that a constriction 42 is formed in the aperture 43 near the lower end thereof and an enlargement 53 is formed below said constriction, which construction results in an open eye accessible through the free edge 41 of the wall II. The constriction 82 also produces proiections III extending into the aperture 43. The width of the neck 48 is substantially equal to the width of the enlarged portion of aperture 4| or the eye 53.

In the use of the invention with cartons for food products. it is frequently customary to wrap the carton in a paper wrapper. One such wrapper is shown in Flg. 2 and is indicated by the reference numeral II. This wrapper may be removed prior to the opening of the carton for use, or the said wrapper left thereon and the carton opened .while the same is in place. In the opening of the carton pressure is placed upon the tab 42 which severs the same from the wall I! and forces the tab inwardly into the interior of the carton. If the wrapper 55 is in place the same is tom in severing the flap. This permits of grasping the top 44 v at the locality of the tab 42 and of raising the portion of top 44 formed by the closure 45 to sever the said closure from the lateral walls of the carton along the perforations 35 and 38. Upon such movement of the closure 45 the same swings about the scores 31 and 38 as hinges. In Flg. 4 the carton is shown as open sumciently to permit of pouring the contents out of the opening IC formed in the upper end of the carton by the removal of the portion of the top 44 constituting closure 45 to its open position. When the closure 45 is in open position the contents may be poured out of theopening 56. When it is desired to reclose the carton the tab 4| is held outwardly in co-planar relation with respect to the closure 45 and the closure' swung downwardly. The neck 46 of said tab is then directed into the aperture 43 and to the eye 53. During such movement the neck is forced past the projeotions 50 formed in the aperture 43 which causes the tab to be locked in place within 'the eye 53. As .will be noted in Fla'.. 5 the closure 45 when in reclosed position becomes arranged obliquely with respect to the surface of the top 44. Since the closure is normally of the length equal to the distance between scores 31 or 3| and edge 41 such disposition of the closure 45 produces a tension between the tab 42 and the wall I! which serves to draw the tab 42 into the neck S3. The Shoulders 48 are preferably arranged in diverging relation so that, as

assaoas the closure is drawn toward the wall ll. the said shoulders are urged against the wall." at the locality of the eye ll. This further prevents the tab from becoming accidentally disengaged and limits the movement of the closure away from the wall IO. After the closure has been reclosed the tab 42 may be folded down along the outer surface of wall IS as shown in Fis. 5.

The advantages of my invention are manifest. An extremely simple and practical construction is provided whereby cartons such as used for breakfast food and the like may be readily opened and whereby theA same may be readily reclosed. The entire structure may be formed from the ma-l terial from which the carton proper is constructed so that no additional material is necessary. The device is easy to operate and the intended use is apparent from a superficial examination of the carton.

Changes in the specific form of my invention. as herein disclosed, may be made within the scope of 'what is claimed without departing from the spirit of my invention.

Having descrlbed my invention, what I claim as new and desire to protect by Letters Patent is:

A carton having front, rear and two side walls, four sealing fiaps each integral with one of said walls along a fold line at its top edge, said flaps being folded inwardly and secured together to form a top wall of the carton, the front wall having a potential opening and closing tab formed therein by a readily fracturable line alon" three sides of the tab, the fourth side of the tab being a part of the integral fold line between said front wall and its top ilap, tear lines extending from the ends ofthe top edge of the tab along the fold line `ioining the front wall and its top fiap to the opposite edges thereof, tear lines extending from the ends of saidfirst tear lines along the fold lines joining the top edges of the two adjacent side walls to the top sealing fiaps,- said tear lines terminating at a score line extending across the carton and adapted to form a hinge, the line deflning the end of the tab being substantially parallel and equal to the line foldably connecting the tab to the top, the lines deflning the sldes' of the tab extending upwardly from the line deflning the end, and converging in'wardly then 'outwardly beyond the width of the tab end, and then inwardly to the ends of the said fold line connecting the tab to the top, thus forming a tab with a medial locking portion.
