CONTAINER BODY AND METHOD OF PRODUCING THE SAME Nov. 2, 1965 Filed DGO. 7, 1962 fm/ y@ dlrel.

United States Patent 3,215,328 CONTAINER BODY AND METHOD F PRODUCING THE SAME Arthur John White, Woodbury, N.Y., assignor to American Can Company, New York, N.Y., a corporation of New Jersey Filed Dec. 7, 1962, Ser. No. 242,976 2 Claims. (Cl. 229-45) This invention relates to a container body and to the method of producing the same and has particular reference to a spirally wound fibre container body having a narrow band or strip interposed between the overlapped edges of the regular spirally wound label on the container body to provide a supplemental label which is particularly adapted for displaying information relating to temporary promotional compaigns.

In an effort to further promote the sale of merchandise packaged in containers, many companies run promotional campaigns from time to time, granting price discounts or making other special offers designed to induce the purchaser to buy the merchandise. In many instances, these companies desire to include information relating to these special offers directly on the package. Normally, this requires a change to the regular container label, thus necessitating a complete new set of printing plates to make the altered label.

As alternatives, the regular label is used, and the promotional information is either printed directly on one of the end members of the container, or is contained in a separate label which is afiixed to one of the container end members. Such procedures add considerably to the cost of the container, and are not effective when the container is displayed in such manner that its body label is presented to the consumer.

The present invention overcomes these problems by providing a spirally wound container body construction wherein the regular spirally wound label is used, and wherein a separate narrow supplemental label band made of a suitable label material such as paper, cellophane,

` foil label stock or the like and containing the temporary advertising material is secured to the container body in such a manner so that it is interposed between the helically overlapped edges of the regular label and extends outwardly beyond the lapped marginal edge portions of the regular label, thus providing an eye-catching advertising device.

This supplemental label is secured to the body during Vthe regular spiral winding operation and its addition requires no substantial changes in the regular body making procedures other than the minimum of equipment necessary to guide the supplemental label to the winding man- Hence, the supplemental labels may be added or discontinued at will, and at minimum expense. In addition, they are securely attached to the body so that they cannot be detached by storekeepers to whom the packages are sold at a reduced price for resalel at a reduced price, and who might desire to delete the temporary advertising and sell the packages at the regular price as regular merchandise.

An object of the invention therefore isV the provision of a container body having a regular spirally wound label which covers substantially the entire exterior surface of the container body and having a narrow supplemental label which extends helically around the body and is secured thereto to prevent surreptitious detachment.

Another object is the provision of a supplemental label which may be added to a container body to augment the regular body label at a minimum of expense.

A further object is the provision of a supplement label which contains an easily detachable premium coupon.

"ice

A still further object is the provision of a method of manufacturing a spirally wound container body incorporating a supplemental label which satisfies some or all of the previous objects of the invention.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

FIGURE 1 is a perspective view of a container having a spirally wound fibre container body provided with a supplemental label which extends outwardly from between the lapped edges of the regular body label;

FIG. 2 is an enlarged sectional view through the body of the container, taken substantially along the line 2 2 of FIGURE 1; and

FIG. 3 is a schematic view illustrating the instant method of making the fibre container body shown in FIG. 1.

As a preferred and exemplary embodiment of the instant invention, FIG. 1 of the drawings discloses a cornpletely sealed container 11 formed with a multi-ply lspirally wound body 12 having an outer spirally wound layer or ply 13 which comprises a regular or standard label which completely covers the exterior surface of the main body 12. The opposite ends of the body 12 are closed and sealed by top and bottom metal end members 14, 15 which are secured thereto in liquid-tight end seams 16 which may be single, crimped seams or interfolded double seams. i

The body portion 12 of the container also includes inner and an outer helically wound main body plies 17, 18 which are glued together and are composed of relatively tough fibre body stock such as kraft, chipboard or the like to provide adequate strength to the container. The edges of the main body plies 17, 18 preferably are disposed inbutt joints 21, 22, respectively, which are arranged in offset relation, one from the other, as best shown in FIG. 2.

The body 12 of the container is protected by the outer label layer 13 which completely covers the underlying main body ply 18 to make the container moisture and water resistant, thus preventing deterioration of the body 12 in the event the container is exposed to water or dampness during storage. For this purpose the label ply 13 may comprise a thin layer of aluminum foil 23 which is prelaminated to a supporting kraft paper backing 24. The longitudinal, helically disposed edges of the label ply 13 preferably are overlapped in what may be designated as a lap joint 25 to more completely protect the underlying main body plies 17, 18 against the penetration of external water and moisture.

The interior surface of the inner main body ply 17 of the container body 12 may if desired be lined with a spirally wound liquid proof liner ply (not shown) or sprayed, coated, covered or treated in any other suitable manner to render it liquid, moisture and grease proof. Since the treatment or covering of this surface forms no part of the instant invention, no further explanation is believed necessary.

The label ply 13 preferably is -of the conventional type which is preprinted with an individual decorative label pattern.

When a company wishes to offer a temporary price discount @or other special inducement to purchase its products, it frequently ydesires to provide additional information somewhere Ion the container 12 informing the purchasing public of its offer.

In order to make it possible to provide such infonmation without necessitating the use of a complete new set of printing plates, as would be necessary if the regular label pattern were to be changed to add information about wound thereon.

the special offer, a supplemental label 26 in the form of a relatively narrow web or strip is provided.

The supplemental label 26 may be formed of any suitable material, such as paper, cellophane -or other plastic, paper-backed foil, plain foil, or the like. If desired, a clear cellophane or similar plastic material may be utilized so that the main portion of the regular label will not 'be obscured by the supplemental label 26 except for the printed ymatter appearing thereon. Usually, however, it is desirable to have t-he supplemental label 26 contrast sharplywith the regular label 13.

The supplemental label 26 is applied to the container lbody i12 in such manner that a longitudinally extending marginal -edge -portion 27 of the supplemental label 26 is interposed between the lapped helical edges of the regular label .13 at the lap joint (see FIG. 2).

The supplemental label 26 is glued to the underside of t-he overlapped edge portion of the main label ply 13, preferably by an adhesive 28 which is applied to the underside of the main label ply 13 during the formation of the container, body, as will hereinafter be described.

This -glue bond serves to hold t-he supplemental label 26 securely in place so that it cannot be wholly detached yfrom the `container except by the obvious destruction of the overlapped edge of the main label ply 13. In addition, the inward pressure exerted by the overlying edge portion of the main label ply |13 tends to hold the supplemental label 26 in place, as does the fact that the supplemental label 26 extends helically around t-he body 1'1 for its -full height, from its top to its bottom edge, so that its ends are incorporated in the end seams 16 and anchored in 'place thereby.

The balance, or remaining longitudinally extending portion 29 of the supplemental label 26 projects outwardly from the lap joint 2S and contains the printed indicia or supplemental label legend, generally indicated by the numeral 30, which is exposed to view.

If it -is desired to incorporate a premium coupon 31 in the exposed portion '29, this is easily done by outlining the coupon 31 with a substantially U-shaped line of weakening such as a score -line or line of perforations 32, both ends of which terminate at the exposed longitudinal edge of the supplemental label 26. Because the exposed porftion 29 is not normally glued down, the coupon 31 may be readily detached from the supplemental label 26 by ytearing the latter along the line of weakening 32.

The supplemental label 26 preferably is applied to the container body 1.1 at the time the regular label 13 is Normally, these operations take place substantially simultaneously Wit-h and as an integral part of the body forming operation.

The preferred method of forming the container body f1|1 is disclosed in FIG. 3 of the drawings. lIn this method, the container body .1,2 is yformed on a stationary mandrel 33 which is anchored securely at one end in a rigid block '34. The other end -of the mandrel 33 is free to permit discharge `of the AWound tube from which the individual container'lbodies 12 are cut.

In making a body 12 constructed as shown in FIG. 2, the inner main body ply 17 is rst wound onto the mandrel 33 at a .point adjacent the block 34. This inner .imain 'body ply 17 preferably is wound with its leading edge abutted against its trailing edge to formnthe butt joint 21 (FIG. 2). A continuous overall film yof a su-itable adhesive preferably is applied to the outer sur- -face of the ply 17 in any suitable manner, as by -a glue applying roll 36, as this ply 1'7 is fed toward the mandrel 33 4 relation of the butt joints 21, 22 of the respective inner and 4outer main body plies 17, 18, the ply y18 preferably is wound on the ply 17 so that the longitudinal edges of the ply 18 are out of alignment with the corresponding edges of the ply 17.

The winding of the inner and outer plies 17, 18, as just described, forms them into a continuous tube 36 lwhich advances toward and passes beneath an endless winding belt 37. This belt 37 operates around a driving drum 38, disposed and driven in any suitable manner at yone side of the mandrel 33, and ,an idler drum 3-9 located in spaced relation from the driving drum 38 at the opposite side of the mandrel 33. A portion .of the belt 37 intermediate the drums 38, 39 is looped around the mandrel 33 Yin tight driving engagement with the tube 36 to advance it helically along the mandrel 33 in order to pull the inner and outer main body plies 17, 18 which comprise the tube 36 from their respective supply rolls (not shown).

After the tube 36 passes through the loop of the winding belt 37 in its advancement along the mandrel 33, it moves into position for receiving the main or regular label ply .13. This regular label ply 13 preferably is slightly wider in its transverse dimension than that of the body plies .17, 18 to provide the overlap which creates the Ilap joint 25 (FIG. 2). The label ply 13, with the paper layer 124 prelaminated to the foil 23, is fed in- Wardly from one side of the mandrel 33 onto the body tube 36 (FIG. 3).

The whole of t-he inner surface of the paper layer 24 of the label ply y13 is provided with an overall coating of the adhesive 28 as it passes over an adhesive applying roller 40. Hence, as the main llabel ply 13 is helically wound onto the tube 36 it is adhesively secured to the 'outer main body ply 18.

The label ply 13 preferably is printed with complete unitary label designs which are printed at an angle to its longitudinal edges and separated from each other at `fthe lines 41. These label designs are so laid out that when the label is Wound onto the tabs, each label design constitutes a regular or standard label pattern. As a result, after winding, the tube 36 is completely covered by the label ply y13 which contains a succession of labels which provide a decorative and protective outer covering thereon.

During the winding operation just described, thel supplemental label 26 is fed onto the mandrel 33 in such manner that its edge portion 27 is caught between and covered by the successive convolutions of the label ply 13. For this purpose, the band 27, having all the special promotional matter arranged and preprinted on its edge portion 29 which is not covered by the regular label 13, is fed at the same winding angle as are the other container plys 13, 17, 18, with its printed portion 29 positioned rearwardly of the trailing edge of the label ply 13 (FIG. 3). As a result, the portion 27 of the supplemental label 26 is caught between and overlapped by the trailing edge portion of the regular label ply 13, while the portion 29 is not, but instead extends outwardly from the lap joint 25` If it is desired to provide the coupon 31, the line of weakening 32 is provided in the supplemental label 26 prior to the time it is fed onto the mandrel 33. This preferably is done as an incident to the printing of the indicia 30.

The winding operations just described result in the formation of a nished tube designated by the numeral 42. As the finished tube 42 gradually moves toward and off the free end of the mandrel 31 it is cut along the spaced lines 41 to divide it into individual container bodies 12. Thereafter, a bottom end 15 is secured onto the bottom end of each container body 12, the container filled with a product, and top end 14' seamed onto the other end of the body 12 to create the finished package.

It will be realized that various modifications of the instant container body construction may be made withoiit departing from the scope of the instant invention. For example, the portion 27 of the supplemental label 26 may be extended inwardly beyond the edge of the underlapped portion of the main label ply 13 so that itcomes into contact with the outer surface of the outer main body 1S to thus more securely attach the supplementary label 26 to the body. If this is done, it may be desirable to coat the inner surface of the covered portion 27 of the supplemental label 26 with an adhesive so that it is glued down, and thus prevent inadvertent peeling of the supplemental label 26 and main label ply 13 in the area of the lap joint 25. In addition, if it is desired to increase the width of the exposed portion 29 of the supplemental label 26, it may be desirable to provide a narrow stripe of Iadhesive on its underside, adjacent its outer edge, to tack it down against the body.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description and it will be apparent that various changes may be made in the form, construction, yand arrangement of the parts and that changes may be made in the steps of the method described and their order of accomplishment without departing from the spirit and scope of the invention or sacricing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
