Be it known that I, RICHARD SUNDERMAN, a citizen of the United States, and resident of New York, N. Y., havejkinvented new and useful) 'Improvements in Cartons or Containers, which invention iSv-fully set fort-h in the following specification.

rlhis invention relates to containers yor cartons and more particularly to cartons having tucked-in closure flaps and the seall closure flap, the same sealing means being eretofore, cartons or containers for cereals and other food products have generally been provided with side and end'top closure iiaps folded one over the other and sealed in the usual manner. (lartonslof this type have generally required the use of a paper in of the same.

bag or liner for containing the cereal on other lfood material and protecting the same after the package has been opened. Lined' cartons of this type are'expensive, and one of the objects of th'e` present invention is to provide a carton or container which is more economical to produce in that it embodies less carton material, which`ma be effectively and readily sealed at the actory and which, after the seal has been broken by the consumer, may be effectively and readily closed by the latter to protect the contents between periods of use without 'the use d of a liner and by the provision of tucked-in closure Haps.

In addition, .the sealing aap or closure is so constructed and arran ed as to be utilized as a pulling tab. This is of particular l importance in the packaging of shoes and the like where it is the customary practicel to store opened packages on shelves in stacks Yor tiers, and where removal of the same is often diiiicult and time-consuming.v Such packages generally comprise rigid box-like structures having separate lids or closures and, due to constant handling, the lids and even the boxes become broken or otherwise rendered unfit for use, necessitating replace- 'ment involving inconvenience and additional expense. Inaddition to losses thus incurred, such containers are costly and,

occupy valuable storage A prior to fillin space which cou d utilized for other purposes..

In this aspect, a further object of the in-` vention is to provide a container which is of simple construction and inex ensive to manufacture, whlch may be rea ily assem# -Abled,vfill ed, and closed byA machinery and methodsv now 'in use Efor similar pur oses,

Jingfa tucked-in closure flap andav portion scalable thereover to prevent accidentalor unauthorized removalof the tucked-inA later/utilizable as a pullin tab for readily removing the contamer om ashelf or other storage S ace. Preferably, t e invention comprises-a collapsible tubular container of general rectangular form and constructed from a vsingle blank of material providing side walls, ilaps forming continuations of said side walls and adapted to be folded one over the other to thereby constitute end walls for the con'- tainer, one of the flaps providing a hinged tucked-in closure, and oneof the continuations providing one or more flaps adapted to be sealed over said tucked-in closure iap after assembly of theblank and providing a pulling tab or tabs after the container has been opened.

The invention is capable of receiving aV Fig. 1 is a longitudinal sectional view of one embodiment of the invention, the Same being taken on line 1-1 of Fig. 4; Fig. 42 is-a plan of the blank from which the Acontainer shown in Fig. 1 is made;

Fig. 3 is a perspective view of several containers embodying the present invention 'and arrangedin stacks or tiers on a shelfr or other support;

Fig. 4 is a transverse sectional view of the container taken on the line 4-4 of Fig. 1; and

Figs15,6,7,8,9 and 1o are fragmentary i I perspective views of other containers embodyingthev present invention.

Referring to the drawings and more particularly to Figs. 1 and 2, the container comprises a collapsible tubular body of rectangular cross section having longitudinal side walls 1, 2, 3, 4 and end walls which are adapted to close opposite ends of the tubular body and which include end iaps 5 and 6, respectively, one or both of which may serting a knife or other suitable instrument under the edge of the flap 7, whereby the tucked-in closure may be removedy and access had to the contents of the packages. After the package has been unsealed the fla-p 7 may be utilized as a pulling tab whereby,

the package may be readily removed from a. shelf or other place of storage. the tuckedin closure flap 5 protecting and preventing loss of the contents of the package. 'Containers embodying the present invention as albove described Yare designed principally. for packagingmaterials such as cereal, coffee, and other food products, but they may also be utilized for packaging articles such as shoes, and the like, and, referring to Fig. 3, packages containing such articles may be opened on receipt of the same from the manufacturer and stored in stacks or tiers on a shelf 8 or other suitablesupport, the unsealed flaps 7 providing pulling tabs whereby individualpackages may be readily removed from stacks or tiers of other packages. p

The container illustrated in Figs. 1 to 4 inclusive is preferably formed. from afolded blank. of paper or other suitable material, and, referring to Fig. 2, the longitudinal walls 1, 2, 3, 4 of the container constitute subdivisions of the blanks as indicated by dotted lines in the ligure, the subdivision constituting the wall 4 being continued to form on the outer longitudinal edge thereof a sealing flap 9- adapted to provide an abutment fo-r the side wall 1 when the blank is folded and sealed to'form the main tubular body portion of the container. v

Thel subdivisions of the blank are each continued at one end to provide respectively end flaps 10, 5, 11, and the projecting sealing and pulling flap 7, and said subdivisions are each continued at the opposite end to provide respectively end flaps 12, 6, 13 and 14, said end flaps constituting end walls for the container when the blank is folded, as

shown in Figs. 1 and 4. The flaps 10, 11 and the fla-p 5 provide respectively inner` and outer plies for' one of the end walls and the -flaps 12, 13, and the flap 6, provide inner and outer plies respectively for the opposite" end wall, the flap 14 providing an intermediate ply fora. purpose hereinafter described. The various sub-divisions of the blank are bent to form the tubular body, as will presently appear, and the flaps have iinperforate connections with said body so that weakening of the same when folded is avoided.

The end fla. 5 is of greater length than the others an terminates in a portion providing a bendable tongue '15 which, after assembly of the blank and filling of the con.-

tainer, is inserted ortucked within the containerbetween adjacent'edges of the end fla- ps 10, 11 and the wall' 4, the end flap 5 and tongue 15 providing a hinged tucked-v in closure whereby materials or articles may be inserted within the container. The flap 7 adjacent the tucked-in portion 15 of the the construction of which requires the occupation of valuable storage. space which could be utilized for other purposes. When it is desired to package materials such as cereals, coffee or other food products, or articles such as shoes and the like, the containers maybe closed at one end by placing the same on formers adapted to feed the containers past well known flap folding and glue applying' mechanisris, and to this end the above described container is provided with the intermediate. ply or flap 14 which is folded over the flaps 12 and 13 and over which the flap 6 is folded and sealed in the usual manner.

The container ist-hen filled, either by maquantities of containers may be assembled E' and filled, the machines only requiring a single attendanta 1 Referring to Figs. 5 tol() incluslve, which illustrate other embodiments of the present invention, 7', ..7 7 indicate res ectlvely for the display of advertising or other mats ter.

It will appear obvious that packages not requiring sealing may embody certain characteristics of the resent invention, particularly the vflap 7 W ich may be utilized alone as a pulling tab whereby indivldual contain ers maybe readily removed from a place of storage suchy as a` shelf or other suitable or in stacks or tiers on the support. v

From the foregoingy disclosure it w111 .be

apparent that the invention provides an eicient and inexpensive container which does Vnot require the use of any special mal chinery or methods in -the manufacture thereof, and it will appear obvious that changes in the construction and arrangement of parts, such as elimination of the sealed end wall and the substitution therefor of a hinged closure, may be made without departing from the invention, such changes being intended to fall within the scope yof the invention defined 1n the appended claims.
