Dec. 26, 1961 l.. TARMINA FOLDABLE CONTAINER 5 Sheets-Sheet 3 Filed July 21, 1958 Filed July 21, 1958, Ser. No. 749,939 1 Claim. (Cl. 229-16) The present invention relates to card-board containers and more particularly, to improved containers providing a rugged construction adapted to contain heavy contents such, for example, as wrapped metal coins.

It is a primary object of lthe present invention to provide an improved container of the above mentioned type including a sheet of die-cut material folded and held in assembled relation without the need of staples or other separate retaining means.

yIt is also an object ofthe present invention to provide an improved cardboard container of the above mentioned type, the end walls of which include there superimposed layers of cardboard providing a very strong end wal-l construction.

Other and more detailed objects of the present invention will be apparent to those skilled in the art from a considera-tion of the following specification, the appended claim and accompanying drawings wherein:

FIGURE 1 is a perspective view of a container constructed in accordance with the present invention;

FIGURE 2 is a perspective View of the container illustrated in FIGURE 1 Showing the cover in the open posi-V tion;

FIGURE 3 is an enlarged broken sectional View of the structure illustrated in FIGURE l, taken along line 3--3 thereof; v t

FIGURE 4 is a transverse sectional View ofthe structure illustrated in FIGURE 3, taken along line 4 4 thereof;

FIGURE 5 is a plan view of a sheet of cardboard after being die-cut and scored ready for folding to form the container illustrated in FIGURE 1;

FIGURE 6 is a perspective view similar to FIGURE 2 showing a container constructed according to a modified form of the present invention;

FIGURE 7 is a plan View of a sheet of cardboard after being die-cut and scored ready for fold-ing to form the container illustrated in FIGURE 6;

FIGURE 8 is a broken enlarged sectional view of the structure illustrated in FIGURE 6, taken along line 8 8 thereof; and l FIGURE 9 is a perspective view similar to FIGURES 2 to 6 showing a container constructed according to a further modified form of the present invention.

Referring to the drawings, and particularly to the container illustrated in FIGURES 1 through 5 thereof, the sheet 10 illustrated in FIGURE 5 may be formed of solid or corrugated paperboard and has been die-cut and scored preparatory to forming it to provide the container I2 illustrated in FIGURES 1 through 4, inclusive. The sheet 1t) illustrated in FIGURE 5 includes a bottom 14, a front wall 16, separated therefrom by a score line 18 and a rear wall 20 separated therefrom by a score line 22. The sheet 10 also includes a top 24 at the opposite side of the rear wall 20 from the bot-tom 14 and separated from the rear wall 20 by-a score line 26. The top 24 has extensions 28 at oppositev ends thereof separated therefrom by score lines 30 which provide end ilaps adapted to extend into the interior of the container as hereinafter described. At its fourth side the top 24 has an extension V32 separated therefrom by a score line 34 and constituting a front Hap also adapted to extend into the interior of the container.

Patented Dec. 26, 1961 YThe rear wall Ztlhas extensions generally indicated at 36 at opposite ends thereof, separated therefrom by score lines 38. These extensions 36 include outer end wall portions 40 which have extending laterally therefrom, at opposite sides'thereof, bottom flaps 42 separated therefrom by score lines 44 and inner end wall portions 46 separated therefrom by double score lines 4S. Each of the bot-tom aps42 has an aperture 50 adjacent to the score line 44. Each inner end wall portion y46 has a projection 52 disposed generally centrally of the side opposite the score lines 4S. The front wall 16 has extensions 54 at the opposite ends thereof'separated therefrom by score lines S6 and constituting intermediate end wall portions which are provided along the side facing the extensions 36 with projections 53. At the side opposite the score line 1S, the front wall 16 has a cut-out portion 60 to facilitate opening of the cover as hereinafter described.

` To form the container illustrated in FIGURES 1 to 4, inclusive, the sheet 10 is folded along the score lines i 38 to fold the extensions 36 upwardly. The extensions 36 are then folded along the score line 44 to fold the lbottom flaps 42 inwardly toa position in which `they substantially overlie the score line 22. The sheet 10 is then folded along the score line 22 to fold the rear wall Ztl` upwardly relative to the botto-m 14. It will be noted that the bottom flaps 42 now overlie the upper surface of the bottom 14. The intermediate end wall portions 54 are then folded upwardly about the score lines 56 relative to the front wall 16 and the front wall 16 is then folded upwardly about the score line 18 to move the intermediate end wall portions 54 into the position best illustrated in FIGURE 3, in which it will be seen that they overlie the inner surface of the outer end wall portions 40. During this movement the projections 5S on the intermediate end wall portions 54 move into the apertures 50 in the bottom flaps 42. The inner end wall portions 46 are then folded inwardly and downwardly about the double score lines 48 until the inner end wall portions 40 assume the position illustrated in FIGURES 2 and 3, in which the inner end Wall portions 40 overlie the inner surface of the intermediate end wall portions 54 and the projections 52 are forced into the apertures 50 to securely lock the container portions in this folded position. The end aps 28 and the front flap 32 of the top 24 are then folded forwardly and inwardly about the score lines fait and 34, respectively, to the positions generally illustrated in FIGURE 2.

The top 24 is then folded forwardly and downwardly about the score line 26 while the end aps 28 and theV The container 62 illustrated in FIGURES 6, 7 and 8,V

and the container 64 illustrated in FIGURE 9, illustrate that the proportions of the various parts of the sheet 10 may be varied to provide containers of different shapes and proportions. Since the corresponding parts of these containers 62 and 64 differ only in their proportions, they have been numbered with the same numbers ernployed in connection With the container illustrated in FIGURES 1 to 5, inclusive. toms are numbered 14, the front walls 16, the rear walls 20, the tops 24, the top flaps 28 and 32, the outer end wall portions 40, the intermediate end wall portions 54, the inner end wall portions 46, the apertures Si), the

It will be noted that in each of the containers 12, 62

Thus, the container botand 64, the end walls consist of three superimposed layers lincluding the outer end wall portions 40, the intermediate end wall portions 54 and the inner end Wall por-tions 46. This insures a very strong and durable construction. 1t will be noted that the bottom aps 42 may completely cover the bottom 14 asin the container 12, or may only partially cover the bottom 14 as in the deeper containers 62 and 64. v

While only certain specific embodiments of the invention have been illustrated and described in detail herein, it will be readily appreciated by those skilled in the art that numerous modications and changes may be made without departing from the spirit of the invention.
