i PRODUCTION or PACKAGES.

Application filed August 22, 19718. Serial No. 250,924.

1o NZZ whom 'it may concern.' A

lie it known that l, firmaron' nn Recon-inns, a citizen of the United States, residing at Staten Island, in the county of Richmond and State of New York, have invented new and useful Improvements in the Production of Packages, of which the following is a specification. v

This invention relates to the production of packages, pertaining-more particularly to the production of a. wrapping kstructure and packages employing such structure.

lilhile the invention is not limited as to its use or application, it is particularly adapted to the packaging of tobacco productsand' especially to the'packa-ging of cigarettes` being capable of meeting the problems which result from the inherent characteristics of a commodity of this type.

For instance, while other forms of tobacco products, such for instance, as plug tobacco, are more or less solid and thus in` herently provide a. shape about which the wrapping can be applied, the inherent shape is not found in connection with a quantity of cigarettes. Each cigarette itself is more or less frail in character, and is therefore somewhat diflicult to package, but vwherev a plurality of cigarettes are employed in the formation of the package, the difficulty increases due to the presence of a'plurality of the frail cigarettes. Gbviously, this charac teristic of the frail condition of the individual cigarette not only is present in the packaging operation-through the difficulty of providing a proper shape to the embryo packet-but also is present. in the package itself, in that there is always a. possibility of application of pressure to the sides of the package, where pressure mayV have the effect of breaking the wrapper-paper or leafor loosening the contents of the cigarette, and render the cigarette less salable or usable.

vWhile the present invention does not pertain particularly tothe manner in which the plurality of cigarettes are maintained in shape during the packaging operation-this forming the subject-matter of a companion application relating to apparatus for producing the package-it d es pertain to the sec-ond of thcse features, in that the package is of a forni in which the inherent characteristics of the cigarettes are maintained and at the same time the package is of such forni Specification of Letters Patent.

as to reduce the liability of breakage or damage to the cigarettes of the package by pressure, as when the package is being carried in the pocket by the user.

This problem is met in the present invention bythe use of a comparatively stiff member or element whi'ch'is introduced into and forms a portion of the package wrapping, this member or element serving to stiften the wrapping in such manne-r as to resist the action of pressure on the contents and thus reduce the liability of damage.

Various ways may be provided for pro-V ducing this result, the drawingsv of the application indicating two diHerent ways, these two forms having many similar characteristics, although the resultant package differs in certain respects in the two formations.

One of the features common in the two forms shown is the fact that .while this stiffening medium is'employed, it is introduced in such way as to practically be out of contact with the cigarettes themselves, forming part of the wrapping rather than serving as a lining elementl for an inclosing wrapper. Consequently the usual foil and paper inclosure may be utilized as the direct cover for the cigarettes, this forming the lining of the wrapping.

Another common feature is that while the wrapping is formed of separate elements or members, they are practically united into a composite whole by the use of adhesive on but one of the elements, the wrapping elements being folded and applied in such manner as to make it possible to provide this more or less unitary structure by the use of adhesive carried by but one of the wrapping elements; Y

One of the features of difference in the two forms shown is provided by the manner in which closing of the package is provided, one form having the folded closing end provided by the foil and paper element of the wrapping, while the other form has this folded closed end provided by the louter vrapping element which may be in the form of a label, it being understood that' the Government revenue stamp overlies the closed end in each form. l

Another feature which may be employedbeing shown in connection with one of the forms-is the utilization of the stiffening element to provide for a restricted opening at the closed end, thus tending to reduce lialOO bility of loss of contents when the package is opened. L

The general object-s of the invention are the production of packages of these general types which can be provided in a simple and eiiicient manner and at comparatively low cost, the production being in such form as to permit of ready formation by automatic macliinery, thus providing for 'large capacity operations.

VTo these and other ends, the nature of which will be readily understood as the inT vention is hereinafter disclosed, said iiiveii` tion consists in the improved package constructions and combinations, together with the methods of producing the same, as hereinafter more fully described, illustra-ted in the accompanying drawings, and more particularly pointed out in the appended claims.

Fig. 15 is a similar view showing the completed package wherein the wrapping elements are those shown in- Figs, 2 and 1p1,

cated iii Fig. 9.

, In each of the two forms shown, the wrapping consists of three elements, the inner element F or F which may be of a single sheet but which, where the wrapping is. to produce a cigarette package, isl preferably ofthe usual foil and paper material; the stiening element R or R formed of suitable material, suoli for instance as card or pasteboard, and the outer element L or L which is preferably of 'thin paper material and which generally carries the label data. The inner and outer elements are preferably of flexible material, although the invention is not limited in this respect. In addition, the package carries the revenue stamp S.

The commodity being packaged is shown asV that ofa plurality of cigarettes C, this forni of commodity being, of course, illustrative. The wrapping elements are shown as in the form of blanks.

As heretofore pointed out, many of the stage operations in the production of theV composite wrapping are the same in both forms shown, and in the drawings l have utilized both forms in illustrating such stage operations, but it may be understood that, generally, the elements F, R and L pertain to one form vct package, while elements F, R and L pertain to the other form, although it will be understood, of course, that this arrangement is not absolute, since, for instance, stifening blank R may be employed with wrapping blanks F and L.

The inner elements F and F, as shown, differ from each other simply in the length of the blank, this being the essential diffen ence between the two blanks where the ele V'ment congurations are of they type shown in the drawings; the outer elements L and.

L"difer :trom eachother in the same inanner, it being understood that both the inner and outer wrapping elements may have other distinguishing characteristics, as by in other respects. Each has a secticn r hav- Y ing a width substantially equal to the width of the package and a length not greater than the length of the package-preferably slightly less-said section carrying wings r of substantially the saine length as section r and having a width approximately equal tion 9', the blank R', however, preferably has section r3 substantially equal in `length to the length of the package, this section carrying an end Wing r" of less YWidth than scction r3, this end Wing being foldable relatively to an end of the package.

rlhe Wrapping is of the type .generally known as a cup formation, the Width of blanks F, F, L and L being such as to provide the material for the production of the cups.

lllhile the inner and stiifening elements may be assembled separatelyas by folding the inner element into a partial cup shape and then presenting the' stiffening element and folding it in position thereon-l prefer to provide the folding of these two elements into assembly formation concurrently, this being permitted by bringing the blanks of the two elements into Contact as in Figs. l and 2` blanks R or R being properly positioned with respect to blanks F or F', the latter being properly positioned relative to the plurality of cigarettes-Which maybe termed a packetso as to locate the end of the packet in contact With that portion of the blanks design to provide the bottom of the cup formation. The tivo contacting blanks are then folded on to the opposite sides of the packet, as in Fig. 3, thus laying the foil and paper element on to opposite faces of the packet With the stiffening ele.

ment overlying the foil and paper element, Wings r2 lying Wholly on one side of the packet, Wing ravhen present, lying on the opposite side of the packet.v The portions of the foil and paper element located at the sides of the bottom-indicated at 20-are then tucked in, asin Fig. 4l, thereby providing side flaps 2l and 22, flaps 2l being formed from the inner element alone While flaps 22 are formed from, this element and the Wings r.

Flaps 22 are then folded on to the sides of the packet, as in Fig. 5, after which flaps 2l are folded on to the outer sides of flaps 22, as in Fig. 6, thus completing the assembly andproviding an embryo Wrapping or cup formation.

its will be seen, this folding places Wings in overlying relation to the foil and paper' portion of iaps 22 and in underlying'relation to flaps 2l, these .wings extending between these tivo portions of the foil and paper cup, the stiffening element thus having an 'overlying and underlying relationto the inner Wrapping element.

rFliese operations described ar the. same with both forms shown, but the resulting formations differ. For instance, when blanks F and R are employed, the ends of blank R do not extend beyond the end of` the packet-they are preferably Vvspaced therefrom a small distance-While the ends of blank F project distance sufficient to provide for folding thereof into a complete closure for the open end of the cup, thus causing the portion of the wrapping which projects beyond theends of the packet to be formed entirely from the inner or foil and paper element. @n the contrary, when blanks F and R are employed, the projecting portions of the inner lelement F are of less length than element F, and end Wing r4 projects beyond the end of this inner eiement, as shown in Figs. et and 6.

rflie more or less tube-like end of either form thus produced, is then folded by tucking in inner element portions 2 3, thus producing end flaps 24 and 25 of one form and 24;l and 25n of the other form, flaps 24 and 25 having a length to provide overlapping of these flaps when folded,r as in Fig. 8, While flaps 2d and 25L are of shorter length and preferably do 'not overlap, flap 25fincluding the projecting Wing rt. and 25M-the latter With wingrt-are then folded onto the end of the packet, this being followed by the folding of flaps2 and 24a, thus placing flap 24rin overlying relation to flap 25 and flap 25?' in underlying relation to flap 2f and Wing rf.'

As will be understood, this folding Will produce an embryo package. In case blanks F and R are employed, this package will have the end entirely closed by the folded end formation of the inner element as in Fig. S. Vlhen, however, blanks F and Hf are employed, the folding does not providethe overlapping relations produced in the first form, the arrangement more closely approaching the formation shown in Fig. 9. f Y

As will be seen by comparing Figs. 8 and 9, the embryo package of each form has the exposed faces of its body portion of similar formation, the bottom, front and rear faces being provided by element R or R', While the sidek faces are provided by portions'of element F or F in addition to the small portion -of Wings 1 exposed on these side faces. Y l'n other Wortes, the exposed faces of the body portion of the assembly Will be provided from both the stiifening and the inner Wrapping elements, these elements, carrying no adhesive faces, being in unsccured relationonelto the other. rlhis provision of exposed faces from both elements is of particular advantage in connection with the completion of the package as presently pointed ont.

ln addition, the Wrapping of each faceof the body portion includes a ply lof the stiffeningelement R or R', thus producing a more lor less stable form or Vshape to the body of the package. There is, however, a difference between the formations at the open end of the cup,as pointed'out.

The package is completed by the application of the cuter Wrapping or label elei'nent Flaps 25 L or L and the application of the revenue stamp. As shown in Figs. 10 and 11, blanks L and L differ from each other in length, element L having` a length approximately equal to the combined length of the bottoni, front and rear faces of the embryo packagcfas seen in Fig. IQ-while element L has a sufficiently greater length to provide the tube-like end formation indicated in Fig. 13, this end formation being folded as heretofore pointed out in connection with element F to produce the closed `end of the package, as indicated in Fig. 15, this end overlying the end formation shown in Fig. 9.

Since the end closure of the form employing blank F is provided by that blank- Pig. S-it will be understood that no supplemental end closure need be provided, so that the productshown in Fig. 14has the exterior of its body portion provided by folded element L with the end closure produced by element F. This differs from the arrangement of the Vother form wherein the exterior of the body portion as well as the end closure is provided by element L.

Blanks L and L" are provided with an adhesively-coated face-either solid, in zones, or otherwise stenciled, as may be preferred. The blanks are folded into the cup shaped formations similar to those heretofore explained and as indicated in Figs. 10 to l5. In applying the element to the. assembly or embryo package, it will be readily seen that the adhesive face is brought into direct contact with the exposed faces of both underlying elementsthe side facesof the inner wrapper element F or .F and the remaininoa faces orovided b stieninc ele-` H i b ment It or It--the result being that while elements F and R orF or It are unsecured to one anotherwith element R or It c`a pable of being readily withdrawn from the folded element F or F by endwise movementnthis application of element L or L serves to not only secure the element L or L in position but alsoto fixedly position'the two other elements relatively to each other. In other words, the application of the adhesively coated element L or L serves to secure the three elements of the wrapping in fixedly positioned relation to eachv other, forming a composite wrapping embodying an inner wrapping element (shown as of foil and paper), an outer wrapping or label element, and a stiffening element interposed between said inner and outer elements, the composite wrapping being substantially the equivalent of a unitary wrapping element having the positive advantage of being produced from different forms of material and in a manner by which the elements can be readily folded mechanically.

The folded end of the package is then closed by the application of stamp S which preferably extends on to the opposite faces of the package as indicated in Figs. l: and 15. Y Y

As heretofore indicated, the package shown in Fig. 14 has the open end of the cup wrapping closed by the end closure formed from the inner wrapping element produced by the overlapping folded end flaps of that element; the overlapping folds, however, not being secured together, the practically sealed condition is provided by the application of the stamp which maintains the iaps closed. IIence, it is neces sary only to break the stamp in order that the folded end may be opened up, this being the usual practice in the cup type of wrapping.

In the .product of Fig. 15, however, this usual practice isv changed.V Here, the closure is provided by the folding of element L and the flaps are tacked together by the adhesive, in addition to which the entire flap is similarly tacked to the exposed portion of wing r4 and the Hap of element F which overlaps this wing, so that not only are the elements of the body portion of the package secured together but the closure formation is of a more or less composite arrangement with the elements thereof adhesively connected.y As a result, removal ofthe stamp will not permit the closure to be opened; in

practice, therefore, a different procedure is.

had in openingthe package. In this form, the user opens up but a portion of the closure end, this result being had by tearing the iiap material of element L atone side of the stampe-a portion which' ,does not overlie wing 9ct-exposing the underlying flap material of element F which may be opened out or torn off, the edge of wing r4 forming a guide during the tearing operation. When this is done, the major portion of the closure remains intact, leaving an opening of sufficient extent to permit removal of the cigarettes as may be desired, thus tending to produce a delivery opening in the closure instead of entirely opening the closure. This 'restricting of the delivery opening is preferred in some instances, and where so desired, the particular formation of the package is of advantage in the production of the opening as will be understood.v In addition, however, there is a` positive advantage presented in the arrangement in that each of the faces of the package is reinforced by the stiffening element, the elosureface not being reinforced in this manner in the form'shown in Fig. 14. y

As will be understood, the cup type of folding to produce the wrapping is preferred owing to the readiness with which it can be produced, but it is to be understood that this form ismore orless illustrative, the invention not being limited thereto excepting as may be specifically indicated in the claims,

since the broad idea of providing a composite wrapping employing two normally unsecured elements which are relatively xedly positioned by the adhesive application of a third element may be utilized with other forms of folding, and it is my desire to reserve the right to such use in so far as the scope of the claims, when broadly construed, will permit.

While l have herein shown and described several ways in which my invention may be carried out, it will be understood that changes and modifications therein may be found desirable or necessary in meeting the exigencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifications therein as may be -found desirable or essential, in so far as the same may fall within the spirit and scope of the invention, as expressed in the accompanying claims, when broadly construed.
