PATENT OFFICE WRAPPED CARTONS AND CONTAINERS Samuel Bergstein,

Qincinnati, Ohio Application April 1a, 1933, Serial No. 666,100;

' 6 Claims. (01.229-87) My invention relates to containers having an outer wrapper secured to the outer surface of the container. There are two types of wrapped containers which are called generally tight-wrapped 3 packages and loose-wrapped packages. The

tight wrapped packages have the wrappers adhesively secured to the container so as to make a sift-proof, air tight package. The loosewrapped packages merely have the outer wrapper folded around the carton, with overlapping ends of the wrapper secured together, but with the wrapper itself not necessarily secured to the walls of the carton. v i

In the art it has been customary in making tight-wrapped packages to apply adhesive to the inner surface of an outer wrapper, and to then wrap and fold the outer wrapper around the container to be tight wrapped. There are two types of wrapping machines for accomplishing this pur- 20 pose. The first type of machine is where the wrapper is fed into position to be wrapped and folded. around the package lengthwise .of the wrapper, and the second is where the wrapper is fed widthwise of the wrapper.

It is the object of my invention to provide a method for applying a thin surface coating to the inner surface of an outer wrapper, when the packages are tight-wrapped, and to further apply thicker' coatings in stripes or beads which, when the wrapper is wrapped and folded around the container, will fill in particularly the crevices between theclosure flaps at'their exposedside' edges and .corners, and which may also be arranged on the wrapper .to fill in any space or crevice atthe corners of the package, whether the machines arebf the longitudinal or the lateral feed type. Another object of my invention is the provision of a novel, hermetically sealed,

tight-wrapped package, in which thicker bands or I contact with the walls of the container. The' pressure is usually applied by means of rollers, or brushes, and any indentations or spacing between the outer wrapper and the container is like ly to develop a weakness in the seal of the package where the "spacing of recesses occur.

lines at the corners, and an outer wrapper will not necessarily secure itself in these indentations, so that in providing filling in beads at the various positions where indentations occur, I form a much tighter, uniform bond throughout between the container and the wrapper. The tighter bond prevents looseness at the corners, which frequently causes the comers to pierce the wrappers.

- In most containers where the side flaps at each end overlap. when the flaps are sealedthere is an unevenness and crevices are formed which it is my purpose to fill in.

In loose wrapped cartons it "ismy object to provide an'additional stripe of adhesive to fill in the crevices at the corners and exposed edges of the closure flaps.

In my application, Ser. No. 664,949, filed'April 7, 1933, I have disclosed a method of filling in the crevices between the plies of the side sealing flaps at the ends of containers by applying an excess of adhesive in a head by means of a timed glue wheel. Mypresent invention has the same objects, only I accomplish them in a different manner.

The above objects and other-objects to which reference will be made in the ensuing description, I accomplish by carrying out the various steps illustrated in the drawings.

Referring to the drawings:

Figure 1 is a plan view of an outer wrapper which has been fed lengthwise of the wrapper and to which longitudinally extending bands of thicker stripes of adhesive-have been applied.

Fig. 2 is a plan view ofan outer wrapper with a container positioned thereon in the usual position, in which the wrapperis folded about the container.

Fig. 3 is a perspective view of the container with the wrapper folded in a rectangular formation about it.

Fig. 4 is a perspective view showing the wrapper with the end portions folded inflush against the top wall of the container. I

Fig. 5 is a perspective view of the container after theside portions of the outer wrapper are folded down into overlapping position and. sealed in place. i

Fig. 6 is a fragmentary viewof the type of carton shownin Fig. 3, with a portion of the extension 4 of the wrapper torn away and folded back.

Fig. 7 is a plan view of a blank which has passed through the adhesive applying rolls widthwise of the sheet, and has had bands or stripes of e I thicker coatings of adhesive placed thereon in Cartons often have angularly indented fold suitable position to fill in the crevices between the .wrapperand the container. Fig. 8 is a plan view of the wrapper with th carton placed thereon laterally of the sheet.

Fig. 9 is a partial section on the line 99 of Fig. 11.

wrapper applied to the canton in the position Fig.1!) is a perspective view of the wrapper shown in Fig. 8 folded into a rectangular formaangular side portions of the wrapper folded down.

In Figs. 1 to 6, a method of applyin the thick stripes of adhesive to the label or wr pper in a machine which feeds the label lengthwise is: in"- dicated. As the wrapper i passes through or into contact with the glue-applying mechanism, a thin coating is deposited over its entire surface, and. by means of indent tions in the glue-applying roll, thick stripes of 'hesi've are positioned length,- wise of thewrapper, as indicated by the areas marked 2. I r

In folding the tight wrapper about the carton, the carton 3 is applied to the wrapper, or the indicated in Fig. 2. The side walls of the wrap-- Fig. 10 with these beads of adhesive in their.

comers.. I j e The first fold, in order'tohave the thick bands of adhesive fill in the crevices 6a,.between the closure iiaps of the carton, will'be as indicated in Fig. 11, inwhich'po'sition the ,ba'n'd of adhesive whichextends along the inner, corners -'of the Y outer wrapper are forced down alongth e end edges ofthe folded-in flaps of the carton, filling" =the 'crevipes In, as indicated in Fig. 9. l0

- Referring to Fig. 11', the second side flapjhavinz \the bands of adhesive extending from the corners of the top flap .of, the carton up to the uppermost edge of the wrapper is then folded in-and the carton assumes the appearance shown in Fig.12, and the band 2a seen in Fig.,.11 will be pressed down and will adhere to the first infolded portion of the wrapper. The triangular ears 1a. formed 'by the above folding are then folded down and assume the position indicated in Fig. 13. 4

The adhesive bands 2a will be pressed downto'flll in the crevices to between the closureilaps. of the carton. A

The method of operation indicated in Figs. 7 to 13 is not as practical asjthe method shown per are hen folded about the carton, with exin Fi s. 1 to t, and itis illustrated merely to incarton is usually on its side, and not on its end,

as illustrated in Fig. 3.

against the top surface of the carton, and in Fig. 5 the extensions at the sides of the carton. are

folded down' and sealed.

Referring to Fig. 6, it will be observed that a portion of the extension 4 is torn back and folded out parallel with the side of the container, andthis indicates how the thick bands 2 of adhesive extend along and mun the crevices which I have illustrated at 6 in Fig. 6. This method prevents any space being formed between the wrapper and the walls of the container, and prevents leakage both by forming a firmer adhesion between the wrapper and container, and by filling in the crevices'which expose the corners of the container so that they are likely to pierce pe forations or holes vin the outer wrapper.

In Figs. '7 and;8 I have shown a wrapper la having bands 2a of thicker adhesive, which may be applied either by passing the wrapper widthwise through adhesive applying rolls having annularly recessed portions which piclfup a thicker coating of adhesive and sodeposit it in bands extending across the; wrapper, or by having a timed glue wheel, having indentations extending lengthwise across the roll which are filled with 'a thicker coating of adhesive, and so deposit the adhesive in the bands or stripes 211 as indicated. In Fig. 8 acarton 3a is indicated in the position in which the wrapperia might be folded around and secured as a 'tight wrapper to the carton, with the lengthwise direction of the carton parallel with the width of the outer wrapper.v I During the passage of the wrapper through the glue applying mechanism, a thin coating of adhesive is deposited over the entire surface of Fig. 4 the end extensions are folded down 1 dicate various modifications of the invention, in

which thick bands of adhesive are applied to the. 'inner surfaces of outer wrappers to improve thestructural strength of a tight-wrapped carton I and to increase its air-proofness and hermetic .sealing qualities. I 4

In making loose wrapped packagesWreferringto Figs. 1-4) in addition to the adhesive stripes 2-2, a band of adhesive isapplied along one edge of the wrapper. This can be done by of a groove in the glue wheel, which may be timed to apply the adhesive to one edge of the wrapper asindicated at 8- 8. In this case the glue wheel is so set that substantially no glue adheres to the entire surface of the wrapper. Another way is to have the stripes applied; by pads extending from the 'glue wheel. Referring to Fig. 3, the wrapper will'have the overlapping ends I secured together by'the bandB-l of adhesive,- During the sealing, adhesive is applied jfolded extensions 4 as indicated at Ill-ll, and" as in the tight-wrapped packages, the bands 2-2 of'adhesive, will fill in the crevices i between the closure flaps of the carton. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: I 1. A metho d of wrappingcartons having crevices -left upon closing, which consists in apply- 55; ing relatively thick beads of adhesive directly to an outer wrapper across the inner surface of said outer wrapper, coincidentally with the application thereto of a thinner film of adhesivetoJ seal the wrapper aboutthe carton, and then applying the wrapper tothe carton so that the beads overlie the portions of the. carton where the crevices are formed. J 2. A tight-wrapped container ham closure flaps leaving crevices and having an outer wrapper secured tothe walls of the container by relatively thin layers of adhesive, and with thicker portions of adhesive in such quantity as to fill f the crevices, directly between thewrapper and the closure flaps of the container. 3. The method of wrapping a paper board carton having'interlapping sealed together flaps at at least one end, having crevices along the edges of the. flaps and at the corners of Junction of the flaps with side walls of the carton, said meth- 0d consisting in taking a relatively thin wrapper of size and shape whereby it is suitable to enclose the carton when wrapped therearound with certain areas extending along said flap edges and across said corners, applying directly to said wrapper, within said areas of said wrapper, beads of adhesive sealing medium restricted substantially to said areas and in such quantities in said areas as will, when the wrapper is wrapped around the carton as aforesaid, fill in said crevices, to seal the crevices and support said areas of the thin wrapper thereat, and then wrapping said wrapper around said carton as aforesaid, and suitably securing said wrapper in its wrapped condition.

4. A method of wrapping a paper board carton having interlapping sealed together flaps at at least one end, having crevices along the edges of the flaps and at the corners of junction of the flaps with side walls of the carton, said method consisting in taking a relatively thin wrapper of size and shape whereby it is suitable to enclose the carton when wrapped therearound with certain restricted areas extending along said flap edges and across said corners, applying a relatively thin coating of adhesive to major areas of said wrapper other than said restricted areas, applying directly to said wrapper, within said restricted areas of said wrapper, beads of adhesive sealing medium thicker than said coating and confined substantially to said restricted areas, said beads being so much thicker than said coating that, when the wrapper is wrapped around the carton as aforesaid, the sealing medium in said beads will fill in said crevices, to seal the crevices and support said restricted areas of the 5. A container comprising a paper board cartonhavlng folded interlapping sealed together flaps at at least one end, along which and at the corners of which crevices are left incident to the folding, a relatively thin wrapper secured around said carton, and sealing medium directly on restricted areas of said wrapper between said areas and edges of the flaps and corners of junction of the flaps with side walls of the carton, said sealing medium being in such quantities as to extend into said crevices along said edges and at said corners, sealing said crevices and supporting said areas of the thin wrapper thereat.

6. A container comprising a paper board carton having folded interlapping sealed-together flaps at at least one end, along which and at the corners of which crevices are left incident to the folding, a relatively thin wrapper wrapped around said carton and having at least major portions of its area secured to corresponding major portions of the areas of the carton by a relatively thin layer of adhesive, and relatively thick portions of sealing medium directly on said wrapper between said wrapper and the edges of the flaps and corners of junction of flaps with side walls of the carton, said sealing medium being in such quantities as to extend into said crevices along said comers, sealing said crevices and supporting said areas of the thin wrapper thereat.
