CAN COMPANY, OF MILWAUKEE, wIscoNsIN, A CORPORATION OF WISCONSIN f CONTAINER Continuation of application Serial No.

This application is a continuation of applica tion Serial N o. 436,102, filed by myself and George O. F rostad on January 10, 1921.

My invention relates to containers, and

5 particularly to containers havinfv an opening at the top which may be closed by a snap closure disk. My ,invention has to do vparticularly with containers of the above character which are made of paper or other m fibrous material.

An object of my invention is the production of a container of the above character and from the material indicated, which-is plain and simple in appearance and in which u all edges 4of the material are concealed and the closure is eii'ected completely so that they contents may be safely kept within the container'. Another object of my invention `is the production of such an article which is 20 thoroughly reinforced at its upper end, andv wherein there is provided a seat for the' clo sure disk, the said reinforcement and seat preferably being unitary and constituting a unitary part of the body material from whichA g5 the container'is made.l i Other advantages o'f my invention will be apparent upon a reading of the following description taken in connection with the accompanying drawings forming apart here- 30 of, and in which: y

Figure 1 is a top plan view of the container with the closure disk in place;

Figure 2 is a longitudinal section through the center of the container;

' Figure 3 is an enlarged detail sectional view showing the arrangement of the upper portion of the container;

Figure 4 's an enlarged detail sectional view showing a modified arrangement of the upper portion'of the container; v

' Figure 5 isl an enlarged detail sectional view of a further modification of the upper por- 'tion of the container; g5 Figures 6, 7 and 8 are enlarged detail views l 436,102, led January' 10, 1921. 1923. Serial 11o-624,042.

This application mcd Inch l9,

of further modifications shown in ve'itical cross section. i

Referring to the drawings, the. bodyv 1 which isfoi' anysuitable material of the character indicated is bent inwardly fat 2 and downwardy at 3, and4 flanged outwardly,-

formi-ng a groove '4. It is then'flanged inwardlyproducing the flange 5. Itis then bent outwardly at 6 and upwardly at 7 'and then back upon itself at 8.. The

vertical portions

7 and 8 lill the space between the body 1 and the `downward portion 3. The vertical or-4 tion 8 in Figures 3 and 4 terminates justa ove' vthe groove 4, thus allowing for the outwardly tianged part' constituting the groovel 4. The portion abovedescribed are accurately formed as. shownin the drawings by the application thereto of` pressure by any suitable die or other forming apparatus, but the pressure thereon is not sluiiicient to cause any deformation of the material or to cause the same to flow, as has heretofore been considered advisable and necessary in the construction of articles of this general character. A

disk closure 9 may be snapped into the position shown in the drawings lfrom the top and is securely held in' position by reasonVO the flexible nature of the material and the construction claimedwThe lower side of the disk rests upon the horizontal portion 5. In

the embodiment lof the invention shown in 4 Figures 2 and 3 of the drawings, a small space is left between` the portions 5 and 6.

' v In the modification shown in Figures land 5, vthe space which is shown between the layers 5 and 6 of the flange in Figure 3 isomitted, vthe two layers in the construction ofv Figures 4 and 5 being in" Contact with each other. The parts in Figure 4 corresponding to arts as shown in Fi ure 3 are marked wit the same numeral wlth the letter a'axed.

In the modification shown in Figure', the

material is continued `downwardly at 10, below the groove, whereas in the other modications the material terminates above the groove. The parts shown in Figure corresponding to similar parts in Figure 3 are marked with the same numerals with the letter b attached. In Figures 4 and 5, certain of the bends or corners are square, whereas in Figure 3 they are round. The c`orners in each of these modifications may be round or square, as desired.

A further change in the construction as shown in Figure 5 is that the groove is pressed outwardly on all of the layers constituting the upperportion of the container. ous modifications, however, have many essential features in common, and it is evident that many other modifications of the details maybe made in the construction without departing from the principles of my invention.

In Figures 6, 7 and 8 are illustrated modifications in which the groove 4 is omitted, the closure disk being held frictionally by the lip of the container. In these figures, the reference numerals corresponding to those in the other figures are employed with, however, the letters c, l and e, respectively. In Figure 6, the material is bent upwardly at 7 and then terminates. In Figure 7 the material is bent upwardly at 7d, downwardly at 8d, the vertical portion 8d in this case extending down somewhat further than in the construction shown in Figure 2. In Figure 8 the material is bent outwardly at 6e, but is not extended up between the plies of the lip. In all these constructions the material isbent back from the edge of the seat, so that there is no exposed raw edge.

, By reason of the construction shown in the drawings and described herein, a container of the character described is produced which has the advantages of a plurality of thicknesses of material at the top or lip por.- tion, and also at the edge of the disk closure, thus providing for an outward flanging of the material at the groove 4, without deforming or weakening the material at the top, where it is desired that the container should have maximum strength and rigidity.

Furthermore, in my container the paper is doubled back upon itself so that there is no exposed edge of the material at the lip of the container. This construction affords adouble thickness folded over instead of a single thickness with an exposed edge. A further advantage of my construction is that when snapping the disk into place, the end 8 of the material will have a tendency to spring inward after the disk has passed over the portion 3, thus keeping the overhanging 11p intact. This overhanging lip will be kept intact or brought back into shape again by the inward pressure of the end 8 of thematerial, even though the overhanging lip is slightly changed during the placing in position of the disk. This is an advantage over'I Vthe construction wherein there is a free exposededge, in which construction there is- The varinothing to bring the overhanging lip back into proper condition.

A further advantage of my construction is that lighter material may be used with a given rigidity at the lip portion of the con-j tainer than would be possible in a construction wherein an edge of the material is exposed.

A further advantage of my construction is that with the reinforced seat 5 there is a flexibility which maintains a perfect seat at all times. During the passage of the disk over the overhanging lip 3, this flexibility lends itself admirably to the reformation of closure disks at the ends thereof, is preferably made of a unitary piece of Ymaterial. This is of great benefit in the manufacture of these articles which, of necessity, must be e inexpensive, but neverthelessV fulfill certain requirements in the trade that they shall be reasonably rugged and of substantial endurance. This device has a further advantage that both ends of the portion comprising the closure disk seat are rigidly fastened; therefore,`the flange 5, 6 upon which,I the disk rests, while rigid enough to form a complete closure, is nevertheless flexible enough to afford the advantages above set forth. The tightness of the closure is also increased by the formation of the groove 4, which, by reason of the fact that the fibres of the material are not deformed, has a certain amount of inherent flexibility, which it does not lose in the construction shown. The presence of such flexibility at that point adds to the tightness of the joint between the diskand the material at the groove.

The expression"face to face, used in certain of the claims in defining the relationship of the seat and the portion lying in substantial parallelism to it, is not to be taken to imply that the two portions referred to must necessarily be in contact, as there may be a separation of such portions, such, for example, as shown in Figures 2, 3 and 6.

I desire it to be understood that my invention is not limited to the exact details shown and described, as many changes may be made without departing from the spirit of my invention as set forth in the appended claims.

I claim:

l icient strength to form the 'outward fold so that the material is folded back upon itself to form a lip of double thickness, and then projectiner upwardly and being folded back upon itseli? to till the space between the outer and inner layers at the top, thus al'ording a plurality of thickness at the top, a plurality of thicknesses at the groove and a plurality of thicknesses in the lip whereby the container is strengthened and given rigidity.
