(Cl. 22B- 4.5)

6 Claims.

This invention relates to improvements in containers which are of the general character of flat bottomed paper drinking cups and may be manufactured on known paper drinking cup machines, the invention being highly desirable for use in connection with the serving or carrying of hot liquids, or a cold substance such as ice cream or the equivalent, or other substances, and capable of carrying such substances for a considerable length of time without any material weakening of the container, although the invention will have other uses and purposes as will be apparent to one skilled in the art.

This application is a continuation-in-part of my copending application entitled Containers and method of making same, filed March 9, 1940, Serial No. 323,055.

More particularly, the invention relates to a container having a multi-thickness wall to strengthen the container so as to enable the carrying of hot or cold substances for a comparatively long time without material weakening of the container and Without objectionable change in the temperature of the substance carried.

I am aware that in the past many and various types of multi-Walled paper containers have been provided, some of which were made from a single blank of suiiicient length to provide several wraps in the finished container, and others from a plurality of blanks glued or otherwise adhesively secured together. However, none of these containers of which I am aware were capable of being manufactured on known machines for forming single-walled flat-bottomed containers of the character of paper drinking cups having the shape of va truncated cones. A single blank of suilcient lengthto be wound twice around in the form of a container body results in too great a wastage of paper stock in the cutting of the blank, and it is too difficult to handle such a blank in cup-forming machines of the ordinary type, owing to the undue length of the blank and the high degree of accuracy with which it must be fed to the machine in order to provide a cup with the edges of both laps in proper register. Further, in most cases of multi-thickness containers as heretofore known, the resultant container was not of a nicely balanced construction, in that a heavy seam ywould be provided in one place on the container, and nothing opposite that seam in order to provide stability and balance throughout the container. Such was especially true in the case where a single long blank was wound twice or more around to form the container body.

With the foregoing in mind, it is an important object of the present invention to provide a container in the nature of a truncated conical paper drinking cup, having a multi-thickness wall and which may be readily manufactured upon known automatic cup-forming machines, which have been designed either for forming a similarly shaped container with but a single thickness wall, or which might be produced by such machines after a very slight adjustment.

Another object of the invention is the provision of a multi-walled container made from a composite blank consisting of a plurality of initially separate blanks, which blanks are secured together in a manner to be handled as though they were a single blank, in the forming of the container body.

A further object of the invention is the provision of a multi-walled container of the character of a truncated conical paper drinking cup, which is made from a plurality of initially separate body blanks joined into a single composite blank, of such shape as to result in a considerable saving of material in the cutting of the blanks.

Still a further feature of the invention is the provision of a container having a multi-thickness wall in the body portion thereof, arranged so as to provide seams evenly spaced around the circumference of the wall to give more strength to the container and to provide a better balancing of this strength throughout the container as a whole, to thus provide a greatly improved container.

'I'he invention also contemplates the provision of a multi-thickness container of the general nature of a truncated conical paper drinking cup, having a bail associated therewith in such a manner that the bail will not come in contact with the contents of the container, and the container being so formed as to provide additional wall thicknesses at spaced intervals so that no additional structure need be provided on the container for the accommodation of the bail.

Another feature of the invention is the provision of a paper container having a multi-thickness wall and made from a composite blank of initially separate pieces of stock, wherein the several wall thicknesses may be of different materials, different colors, and certain of which may be printed or not, as may be desired, with the composite blank so formed being treated as a single blank in the formation of the container body.

It is also a feature of this invention to provide cated conical paper driking cup from a composite blank made up of as many initially separate pieces as there are thicknesses between seams in the resultant container wall, each one of such separate pieces being smaller than a single blank for making a single thickness container body of substantially the same size, and in many instances certain of the pieces going to make up the composite blank being considerably smaller than such individual blanks for a single thickness container wall.

Still another object of this invention resides in the provision of a multi-thickness container of the character of a paper drinking cup in the general shape of a truncated cone wherein a portion of the body isturned around a ilange on a bottom member, and the construction is so arranged as not only to provide a very marked saving of material in the provision of the composite blank going to make up the container body, but also to provide a container wherein the weight of a full container resting upon a surface will not be entirely carried by that portion of the body which is turned in around the bottom member; and, if so desired, the construction may be carried out so that the weight of the full container is carried by means entirely to one side of the bottom fold-over portion.

As shown on the drawings:

With reference to Figures l to 6, inclusive,

it will be seen` that the rst form of body blank and container made in accordance with this invention includes a body blank seen more clearly in Figure 1, which is made is made up of a pair of initially separate pieces I and 2 secured together in the overlapping portions thereof by adhesive 3 or equivalent means which substantially covers the entire inside face of the piece I. In this instance, the two blanks are overlapped for substantially half the length of each blank, so that the resultant composite blank is approximately 11/2 times as long as either of the pieces i and 2. In the resultant container body, the stock piece I will be disposed on the outside, and the stock pieceA 2 on the inside.

The initial pieces I and 2 are of substantially similar shape and each comprises an arcuate piece having a curved edge at one end to form a portion of the mouth of the nished receptacle, a curved edge at the other end for association with the bottom member to be later described, and a pair of converging straight side edges. 'I'he blanks I and 2 are arranged so that the curved mouth-dening edges coincide in the overlapped'regions to provide a complete edge 4 which extends twice around the mouth edge of the resultant container. The outer blank piece I is Wider than the inner piece 2 and elxtends below the inner blank, as indicated at 5, to provide a margin for association with the bottom member of the nished container. The inner piece 2 is also provided with a stripe of adhesive 6 at its inner lower margin for association with the outer side of the ange on the bottom member, and also'with an adhesive stripe 'I adjacent its inner end margin to provide a side seam with the outer end margin. The outer end margin of the inner piece 2 preferably has an outstanding central portion 8 deined by oblique end cuts S11-8a, leaving the portion 8 free and devoid of adhesive 6, to be gripped by forming means.

4It will be seen that with the blanks overlapped to substantially half the length of each blank. the composite blank will form a double-walled container when wound one and one-half times around, and thus provide a triple ply seam at two opposite points in the container body.

It will be appreciated, of course, that a considerable saving in material results in the cutting of the two initially separ .ite blank pieces I and 2 from a sheet or ribbon of stock, over the cutting of a single long blank which is wound twice around to provide a double thickness container body. In cutting a blank suiciently long to be wound twice around, there is considerable wastage between the adjacent arcuate edges of successive blanks, and the triangular waste portions resulting from the cutting of the converging side edges are rather considerable in size. In cutting the pieces I and 2 for the composite blank, the waste space between adjacent arcuate edges of adjacent blanks is relatively small, and the triangular shaped waste piece resulting from the cutting of a converging edge is frequently less than half the corresponding triangular waste piece resulting from the cutting of a blank sufliciently long to be wound twice around. It will be noted that the resultant saving of material varies to some extent, depending upon the size and shape of the resultant container. For instance, the saving resulting from a comparatively high and slender container will be different from the saving resulting from a squat container.

although in any instance the saving should not be less than 10 percent, and frequently exceeds 20 percent, so that on the average it might fairly be said that a 15 per cent having results from the practice of the principles of the present invention in the manufacture of the blanks and cups embodied herein. This represents a very substantial and considerable saving in this type of manufactured product.

The container of which the body portion may be made from the blank seen in Figure 1 is illustrated in Figures 2 to 6 inclusive. The container includes a. bottom member 9 having a depending annular dangle I0. The projecting marginal portion 5 of the blank piece I is turned inwardly and upwardly around the flange I0, as seen clearly in Figure 4, to unite the bottom member 9 to the body portion of the container made up from the composite blank. When the composite body blank is wound into container shape, a pair of triple ply seams I I and I2 are provided on opposite sides of the container. In other words, these seams are spaced equidstantly around the circumference of the container so as to provide greater strength and better balance and stability to the container as a whole. When the body portion is wound about the bottom member, the adhesive stripe Ii unites with the flange I0 on the bottom member, and the adhesive stripes l and 8 establish seams II and l2.. At the mouth end, the container is preferably provided with a downwardly turned or rolled rim bead I3, which not only provides a smooth drinking or pouring rim but adds to the general strength and stability of the container. A suitable distance below the rim bead I3, the container is internally grooved to provide an outwardly extending hollow bead I4, and the groove thus formed in the provision of this bead functions as a seat for a suitable disk cap or closure I5 (Figure 6) which may be used, if desired, to protect the contents of the container.

Preferably between the annular bead Il and the rim bead I3, the container wall may be provided with a pair of apertures to accommodate the ends I6 and I1 of a bail I8, these apertures preferably being located in the triple-ply side seams II and I2 so as to provide a reinforced anchorage for the bail. In applying the bail to the container, which may be done after the container has been filled, it is only necessary to spring the ends I6 and I1 into position, where they will remain, due to the inherent tendency of the bail to contract. It will be noted that still further support for the bail is given by the rolled rim bead I3, and it should also be noted that the inner ends I6 and I1 of the bail extend inwardly in position'over the cap I5, so as to prevent accidental dislodgement of the cap. When it is desired to remove the contents of thc container, it is a simple expedient to remove the bail wire by withdrawing the ends I6 and Il thereof from the container body, whereupon thc cap may be readily removed.

With this arrangement it will be appreciated that the cups or containers may be made and assembled in stacked relationship, and so delivered to the retail dealer or user. The bails may be provided in a separate package. Thus, much less space is occupied than would be the case if the cups were delivered to the user with the bails already attached. Consequently, it is a simple procedure for the user to remove a cup or container from a handy dispenser, ll the container with the desired content, insert the cap I5 and, if a bail is desired, attach it to the container. If no bail is desired, then no bail is wasted.

A novel method for making the blank seen in Figure 1 and the container above described, as well as the other blanks and containers to be later described herein, is more fully set forth and claimed in my aforesaid copending application.

In Figure 'l I have illustrated another form of composite. blank, which results in a still greater saving of material over the composite body blank seen in Figure 1. In this instance the composite blank is made up of two initially separate pieces I9 and 2li secured together in echelon arrangement by the adhesive 2| or the equivalent, which preferably covers the entire inner face of the piece I9. The added saving in material results fromthe fact that the pieces I9 and 20 are of substantially the same size. whereas, in the blank seen in Figure l, the outer piece 1 was of greater width than the inner piece 2.

The echelon arrangement of the initially separate pieces I 9 and 20 of the blank of Figure 'l leaves a margin 22 of the outer blank I9 projecting beyond the inner blank at one side edge, and a margin 23 of the inner blank projecting beyond the outer blank at the opposite side edge of the composite structure. Likewise, a margin 24 of the inner blank projects above the outer blank. and a margin 25 of the outer blank projects helow the inner blank. A suitable stripe of adhesive 26 may be provided on the inner blank adjacentthe lower edge thereof for engagement with a bottom member, and a stripe of adhesive 21 may be provided on the inner end margin for establishing a side seam connection with the margin 23 which, in the main, is free and devoid of adhesive so that it may be gripped by forming means.

In forming the composite blank of Figure 7 into the body portion of a cup or container, only one revolution of the composite blank is necessary. The body blank is wound around a bottom member 28 having an annular dependingilange 29 which, in the resultant cup as seen in Figure 8, is engaged by the protruding margin 25 of the outer blank piece. After the winding of the composite blank, the protruding margin24 of the inner blank piece is turned outwardly and downwardly over the upper edge of the outer blank piece, to provide a curled rim bead 30, and spaced inwardly from this rim bead an outwardly 'projecting hollow bead 3| may be provided to establish an internal cover-receiving groove.

In Figure 10 I have shown a sectional view of a container which may be made from the composite blank of Figure 7. It will be noted that in winding the composite blank, the two side edges of each blank piece may be brought into abutment so as to provide a smooth ush butt-seam 32, whereby no portion of the body part of the container is thicker than any other portion. Thus, a balanced construction is provided, and with this construction a. bail may be used in the manner above described, although the bail will not have as many thicknesses of stock for its anchorage as is the case in the structure shown in Figure 6.

It will be further noted that iny reference to Figure 8 I have shown the blank piec l5 and 20 as of different thicknesses, to indicate not only that they may be of different thickness, but of a different quality of stock. Obviously, either blank may be of a different color than the other, printing may be provided on one of them, and such variations in construction as may be desired for a particular usage may thus be supplied. This is, of course, true with any of the composite blanks discussed in this Specification.

It might also be desirable to have an outside bottom member matching in color or other decoration with the outside of the container body, and with this in mind I have illustrated, in Figure 1l, the use of such a second bottom member. It will be seen that the bottom member 28 is disposed in its usual position and the bottom member 33 is nested within the bottom member 28. The margin 25 of the outer blank piece is then engaged around the depending flanges on both bottom members.

v It should also be noted that it is not essential that the composite blank of Figure 7 be formed into a, butt-seamed container body as seen in Figure 10. If so desired, a lap seam of the character seen in Figure may be used. In that event, the container will be thicker at the seam than anywhere else in its body portion.

In Figures 12, 13 and v14, I have illustrated another form of composite blank and cup or container made therefrom. This composite blank is formed so as to provide a double thickness fold-up over the ange of the bottom member in the completed cup. In this instance also, I have shown how a blank of the general character of the blank of Figure 'l may be used to provide a lap seam in the completed vessel, rather than the butt-seam previously described. 4 e

In this instance, an outer blank space 34 and an inner blank piece 35 are secured together in echelon arrangement by means of adhesive 36 or the equivalent which substantially covers the en-` tire inner face of the piece 34, in a manner to provide a projecting margin 31 of the outer blank on one side, and a projecting margin 38 of the inner blank on the other side, with a projecting margin 39 of the inner blank at the top of the composite blank. 'I'he inner blank is somewhat wider than the outer blank, so that at the lower edge of the composite blank the two blank pieces lare coincidental. For a lap joint three stripes of adhesive are preferably utilized, namely, adhesive 36 on the projecting rmargin 31, stripe 40 on the inner end margin oi piece 35, and a curvate stripe 42 on the inner bottom margin of the piece 35 vof sufilcient width for engagement with both sides of a bottom flange member. I'he margin 38 is left free for gripping by forming mechanism.

When the composite body blank is rolled onceI around a bottom member 43 having a depending flange, the lower marginal portion of both blank pieces 34 and 35 are turned around the ange of the bottom member, as indicated at 45 in Fig. 14. If so desired, two bottom members may be used, as shown in Fig. 11. The winding of the composite body blank also results in a quadruple thickness lap seam 46, as seen in Fig. 13, but. as before explained, a butt seam of the character seen in Fig. 10 may be utilized with the yblank of Fig. 12, if so desired. For the same capacity cup, a butt seam provides an added saving long as is necessary to provide a lap seam or the character of the seam 46 and still maintain the saine capacity. The body pieces 34 and 35 may be of different quality stock, different colors. diierent thicknesses, and one may contain printing or not, as above described.

In Figures 15 to-19, inclusive, I have illustrated another form of blank and container embodying the principles of this invention, wherein the container body is given still an added thickness of material, resulting in a triple-ply wall with quadruple ply seams, andthe design is such as to transfer some oi' the weight of the filled container away from the bottom fold-up around the ilange of the bottom member or members.

In this instance, a composite blank is made up of three initially separate' pieces 41. 48 and 49. the two outer pieces being overlapped on opposide sides of the center piece 48 and secured thereto by adhesive or the equivalent. With reference to Figure 16 it will be seen that the inside blank piece 49 is slightly wider than the outside and middle pieces 41 and 48, so as to provide a projecting margin 58 which will be at the lower end of the finished vessel. At the upper side, all of the blank pieces are in alignment so as to provide a relatively continuous mouth defining edge.

In forming a container, the composite blank is rolled around a bottom member or bottom members, two members 5| and 52 in nested relationship being illustrated in Figure 18. The composite blank is rolled with the wider piece 49 on the inside and is turned a fraction of a turn over two revolutions in order to provide the cup body. Three seams of quadruple thickness, 53, 54 and 55 will thus be provided, spaced equidistantly around the circumference of the cup or, in this instance, substantially apart, center to center. The triple thickness wall, plus the quadruple thickness seams spaced equidistantly, provides an exceptionally strong and stable cup. As seen in Figure 18, the protruding margin 5I of the inner blank piece 49 is folded over around the depending flanges of the bottom. members 5I and 52 in order to unite the body and bottom of the cup. The other body blank portions 41 and 48 terminate flush with the fold-over of the margin 50 as indicated at 56 in Figure 18, so

that the lower edges of these outer blank pieces rest upon the same surface with the bend of the would be acting if the body of the container was also only of a single thickness.

The triple thickness cup may also be provided at its mouth and with a rolled rim bead 51 and with an outwardly projecting hollow bead 58 spaced somewhat inwardly from the rim bead in order to provide an internal groove for a cover member if the same should be desired. It is clear that a bail might be used with the cup shown in Figures 17 and 18 by simply providing a. pair of apertures between the rim bead and the bead 58 to accommodate the bail ends as above described in connection with the showing in Figure 6. Obviously, also, the pieces 41, 48 and 49 going to make up the entire composite blank may be of dierent thicknesses, different qualities, different colors, and certain of them may be provided with printing, if desired. only one bottom member is desired, as shown in Figures 4 and 8, only one, of course, need be used.

In Figures 20 to 22, inclusive, I have shown still another form of composite blank and the cup made therefrom, embodying principles of this invention. The composite blank seen in Figure 20 results in a greater saving of material than any of the other composite blanks discussed hereinabove.

Figure 20 is a plan view of the inner face of a composite blank including an outer blank piece 59 and an inner blank piece 60, joined together in overlapping relationship for substantially half their length and held by a suitable adhesive 8l or the equivalent. In this instance the adhesive 6I is carried over substantially the entire inner surface of the outer blank piece 80, so that when the composite blank is rolled the outer piece is cemented to the inner piece all the Way around. The inner piece 59 is wider than the outer piece 80 so as to leave a relativelywide margin 52 of the inner piece projecting above the outer piece, and also to leave a margin 63 of the inner piece projecting below the outer piece. A stripe of adhesive B4 is preferably provided adjacent the inner side margin of the inner piece 59 forengagement with the opposite and outer side margin of the same piece to provide a seam.66 seen in Fig. 22 when the composite blank is rolled into a cup body. Likewise, a curvate stripe of adhesive 65 is provided for engagement with a bottom member 61 having a depending ange 88, seen in Fig. 21. The outer side or end margin of -the inner piece 59 is left free for gripping engagement by forming means.

When the blank is rolled about the bottom member 61 into container shape, the ange p'ortion 63 projecting from the lower portion of the inner blank 59 is folded inwardly about the flange E8 of the bottom member in the manner previously described. However, the outer blank is of suflicient width to extend slightly below the bend of this bottom fold-over seam, as indicated at 59 in Figure 2l. This portion 69 is free from the adhesive 6|, as shown in Figure 20, the adhesive 5I covering the entire face of the outer blank 80 except for this norrow margin 58. Thus, with reference to Figure 21, it can be seen that the entire weight of the filled vessel will be carried by the outer blank piece 60 alone, the lower edge of which is the only portion of the cup contacting the surface upon which it may rest.

In the completed vessel, a rolled rim bead 10 may be provided, and spaced therebelow a hollow outwardly `projecting bead 1I may be formed to provide an internal cover groove. Both the bead 10 and the groove bead 1l are formed in only the projecting marginal portion 62 of the inner blank piece 59. Obviously, the container seen in Figures 21 and 22 may be made on known cup-forming automatically operating machines, because in the fold-over at the bottom seal of the container the mechanisms are only working upon a single thickness of material, and the same is true with respect to the provision of the groove bead 1| and the rim bead 10. In this particular form of the invention there is provided a double walled receptacle highly desirable for use in connection with the packaging of hot or cold sub- 25 stances, a vessel having considerable strength and stability,` and yet one wherein a great saving of stock is provided in the manufacture of the container, and one in which the weight of the vessel is transferred from the bottom fold-up seam, so

as not to place any added strain upon this seam, a feature especially desirable upon occasions where the cup is left filled with a hot liquid for a considerable length of time.

. It is obvious, 0f course, that the container of Figs. 21 and 22 may be made with either one or two bottom pieces, as desired, and ,the blank pieces 59 and 'E0 may be of different quality, color, thickness, etc.

From the foregoing, it is apparent that I have provided an invention embodying a novel container having a multiply wall, which is exceedingly simple in construction, yet entirely rigid,

extremely durable, and perfectly balanced. Moreover, the construction of the vessels embodied in this invention is contingent upon a very marked saving of material. It will also be appreciated that the invention readily adapts itself for optional use with a bail, which not only may be readily attached to the container but, when attached, does not come in contact with the contents of the container, and actually aids in maintaining the cover in position over the contents. Further, the invention embodies certain features of construction whereby the weight of' a filled vessel is partially or wholly transferred from the fold-up-seam at the bottom of the vessel.-

It will, of course, lbe understood that various details of construction may be varied through a wide range without departing from the principles of this invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

I claim as my invention:

1. A flat-bottom paper cup including a bottom member, and a multi-ply body part formed from initially separate pieces secured together, a marginal portion of one of said pieces being folded around the flange on said bottom member to provide a bottom closure seal. and another of said pieces extending below the fold of said bottom closure seal in position for the cup to rest solely on the edge of this last said piece.

2.
