FIGURE 19 is a perspective view of another container of this invention. I

Referring to the drawings in detail, a container 16 constructed according to this invention is shown in FIGURE 1. The container 16 is made from a generally coplanar sheet or blank 18 shown in FIGURES 5 and 6. The sheet or blank 18 is formed in a predetermined irregular configuration as illustrated. The sheet or blank 18 is made of any suitable material, preferably, cardboard or paperboard or plastic or the like.

The sheet or blank 18 has a rectangular side panel 20 and a rectangular side panel 22. Intermediate the rectangular side panels 20 and 22 is a side panel 24 which has edges 25 which converge. Thus, the side panel 24 may be referred to as trapezoidal in shape. A side panel 26 has converging edges 27 and is also trapezoidal in shape. The rectangular side panel 22 is intermediate the trapezoidal side panels 24 and 26. Thus, one side edge 27 of the rectangular side panel 22 coincides with a side edge 27 of the trapezoidal side panel 26, and the other side edge 25 of the rectangular side panel 22 coincides with a side edge 25 of the trapezoidal side panel 24. The trapezoidal side panel 26 has an upper edge 21 and a lower edge 23, which are substantially parallel one with respect to the other. The trapezoidal side panel 24 has an upper edge 28 and a lower edge 29 which are substantially parallel one with the other. The trapezoidal side panels 24 and 26 are shown as having the same dimensions, but are inverted one with respect to the other.

The rectangular side panel 20 has lower and upper edges 33 which are equal in length and parallel one with the other. The rectangular side panel 22 has lower and upper edges 35 which are equal in length and parallel one with the other.

The rectangular side panel 20 has a flap 30 at one end thereof and a flap 32 at the other end thereof. The rectangular side panel 22 has a fiap 34 at one end thereof and a flap 36 at the other end thereof.

The trapezoidal side panel 24 has a flap 38 at one end thereof and a flap 40 at the other end thereof. A fold line 42 is shown bisecting the trapezoidal panel 24 and the flaps 38 and 40. The trapezoidal side panel 26 has a flap 44 at one end thereof and a flap 46 at the other end thereof. A fold line 48 is shown bisecting the trapezoidal side panel 26 and the flaps 44 and 46.

A flap 50 joins the flap 30, and a flap 52 is joined to the flap 50 and to the flap 38. A flap 54 is joined to the flap 38 and to a flap 56. The flap 56 is also joined to the flap 36. A flap 58 is disposed intermediate the flap 36 and the flap 46. A flap 60 is also joined to the flap 46.

An attachment strip 62 is joined to the flap 60. An attachment strip 64 extends from one end of the attachment strip 62. The attachment strip 64 is disposed along shown in the edge of the trapezoidal side panel 26. An attachment strip 66 extends from the other end of the attachment strip 64 and is joined to a flap 68 which is also joined to the flap 44.

A flap 70 is disposed intermediate the flap 44 and the flap 34 and is joined thereto. A flap 72 is disposedintermediate the flap 34 and the flap 40 and is. joined thereto. A flap 74 is disposed intermediate the flap 40 and the flap 32 and is joined thereto.

Preferably, suitable fold lines are formed in the blank 18 by scoring or the like along the edges of the side panels and between adjacent flaps and strips.

Any suitable adhesive material may be employed to secure portions of the blank 18 one to the other to form a container 16. Preferably, pressure-sensitive or temperature-sensitive adhesive material is applied to the strips 62, 64, and 66 and to flaps 60, 58, 68, 7G, 72, and '74 of the surface of the blank 18 as illustrated in FIGURE 5. Such adhesive material is also applied to the surface of the flaps 58, 60, 72, 74, 70, and 68 of the blank 18 as shown in FIGURE 6. Adhesive material is also applied, as shown in FIGURE 6, to a strip 80 at the edge of the flap 30 and to a strip 81 at the edge of the flap 50 and to a strip 82 at the edge of the flap 52 and to a strip 83 at the edge of the flap 54 and to a strip 85 at the edge of the flap 34. It is to be understood, of course, that adhesive material other than pressure-sensitive or temperaturesensitive adhesive material or other attachment means may be employed in regard to a container of this invention.

If desired, the blank 18 may be folded upon the fold lines 42 and 48. The surfaces of the strips 62, 64, and 66 to which adhesive material has been applied, as shown in FIGURE 5, are then placed into engagement with the right hand edge of the flaps 30 and 32 and the panel 20 for attachment thereto. Thus, the strips 62, 66, and 64 are secured to the edge of the flaps 30 and 32 and the panel 20, respectively. The blank 18 then appears substantially as shown in FIGURE 7. If pressure-sensitive adhesive material is employed, protective sheet material (not shown) is used to cover the other portions of the blank 18 to which the pressure-sensitive material has been applied to prevent adhesion with any other surface or element. In the form shown in FIGURE 7 the blank 18 can be easily stored for future use. Also, in the form shown in FIGURE 7, the blank 18 can be readily packed for shipping.

It is to be understood that the blank 18 does not need to be first formed into the shape shown in FIGURE 7 in order to form a container. If the step shown in FIG- URE 7 is eliminated, the fold lines 42 and 48 do not appear in the blank 18 as it is shown in FIGURES and 6.

The next step in forming the blank 18 into a container 16 is that of opening the blank 18 to substantially the form thereof shown in FIGURE 8. Any protective sheet material employed to cover the adhesive material is removed therefrom.

As shown in FIGURE 9, the bottom of the container 16 is formed by folding the flaps 68 and 70 to cover the flap 44 as the flaps 68 and 70 are adhesively attached to the flap 44 by applying pressure thereto. The opposite surface of the flap 70 is adhesively attached to the flap 34 as the flap 34 is folded over the flap 70. The flaps 72 and 74 are folded into engagement with the flap 40 for adhesive attachment of one surface of each of the flaps 72 and 74 to the flap 40. The opposite surface of the flap 72 is attached to the flap 34. The flap 74 has the opposite surface thereof attached to the flap 32. Then, the strip 85 of the flap 34 is moved into position to cover a part of the flap 32 as the strip 85 is adhesively attached thereto.

As shown in FIGURE 10, the top part of the container 16 is formed by folding the flaps 58 and 60 into engagement with the flap 46 so that one surface of each of the flaps 58 and 60 is attached to the flap 46. The opposite surface of the flap 58 is attached to the flap 36 as the flap 36 folds over the fiap 58. The opposite surface of the flap 60 is attached to the flap 30 as the flap 30 folds over the flap 60. Then, the flaps 52 and 54 are folded to cover the flap 38. The adhesive strip 82 upon the flap 52 shown in FIGURE 6 is attached to the fiap 50, and the adhesive strip 83 upon the flap 54 shown in FIGURE 6 is attached to the flap 56. Following this, the strip of the fiap 30 and the strip 81 of the flap 50 are moved into position to cover a part of the flap 36 and to cover a part of the flap 56, as illustrated in FIGURE 10, as the strips 80 and 81 are adhesively attached thereto.

Thus, the container of FIGURE 1 is formed. It is to be noted that as the container 16 is formed, the upper edges 21, 35, 28, and 330i the side panels 26, 22, 24, and 20, respectively, become substantially coplanar and the bottom edges 23, 35, 29, and 33 of the side panels 26, 22, 24, and 20, respectively, become substantially coplanar. Thus, the bottom and top surfaces of the container 16 formed by the various flaps are substantially fiat and parallel. Thus, the container 16 has a substantially flat cover at the top thereof and a substantially flat base at the bottom thereof.

Either the bottom part of the container 16 or the top part thereof may be formed first. The container 16 may be filled through either the top or the bottom thereof when that part of the container 16 is disposed upwardly.

The container 16 is adapted to contain a liquid or a powder material, or a granular material, or the like.

As illustrated in FIGURE 3, the flaps 52, 54, 38, 50, and 56 are adapted to form a pouring spout. The pouring spout is formed as follows: The flaps 52 and 54 are lifted away from the flap 38, thus separating the strip 81 from adhesive attachment with the flap 56. Then, the flaps 52 and 54 are separated from adhesive attachment with the flaps 50 and 56, respectively. Then, the flap 38 is pulled forwardly and formation of the pouring spout is completed. In order to permit such formation of the spout after assembly of the container 16, adhesive attachment of the flaps 52 and 54 to the flap 38 is to a rather limited degree.

It is to be noted that in the formation of the container 16 shown in FIGURE 1, the panels 20, 24, 22, and 26 shown in FIGURES 5 and 6 form the side walls of the container 16. The surfaces of the side panels 20, 24, 22, and 26 shown in FIGURE 5 become the exterior surfaces thereof. As shown and discussed, the panels 20 and 22 are rectangular in shape. Thus, the upper edge 35 of the panel 22 is equal in length to the bottom edge 35 thereof and the upper edge 33 of the side panel 20 is equal in length to the bottom edge 33 thereof. The panels 24 and 26 have side edges 25 and 27, respectively, which converge. The side edges 25 of the panel 24 converge to ward the upper part of the container 16 and the side edges 27 of the panel 26 converge toward the bottom part of the container 16. Thus, the upper edge 21 of the side panel 26 is longer in length than the bottom edge 23 thereof and the uper edge 28 of the panel 24 is shorter in length than the lower edge 29 thereof.

Also, as stated above, the bottom and top surfaces of the container 16 are substantially flat and parallel. Therefore, when the blank 18 is formed into the container 16, there is relative lateral angular movement between the upper edge 35 of the side panel 22 and the bottom edge 35 thereof, so that the upper edge 35 and the bottom edge 35 of the panel 22 become disposed in different planes. Also, in like manner, the upper edge 33 of the side panel 20 and the bottom edge 33 thereof become disposed in different planes. Thus, the rectangular panels 20 and 22 each assume a curved shape. FIGURES 1, 3, 4 and 8 show the rectangular side panels 20 and 22 curved inwardly. FIGURES l2 and 13 show the rec tangular side panels 20 and 22 curved outwardly. Because of the outward curvature of the side panels 20 and 22, rather than an inward curvature thereof, the volumetric capacity of the container 16 of FIGURE 12 may be some what greater than the volumetric capacity of the container 16 of FIGURE 1.

Such curvature of the panels or side walls 20 and 22 provides strength to the container 16 Which would not otherwise be possible. The container 16 is capable of resisting appreciable internal or external pressures or forces without distortion or collapse thereof.

Due to the fact that the upper and lower surfaces of the container 16 are substantially fiat and parallel, and due to the fact that a container 16 is capable of resisting appreciable external forces, a plurality of containers 16 can be stacked one upon another, as illustrated in FIG- URE 2. Even though a plurality of containers 16 are filled with material, the containers 16 can be stacked in a plurality of layers.

Furthermore, the concave side panels 20 and 22 of the container 16 of FIGURE 1 provide recesses which facilitate manual grasping of a container 16 during pouring therefrom, as illustrated in FIGURE 3, or for any handling of the container 16. When the container 16 is disposed at an angle for pouring therefrom, as illustrated in FIG- URE 3, the center of gravity of the container 16-, including the contents thereof, shifts to a lesser degree toward the pouring spout than occurs in pouring from a conventional type of container which is substantially a parallelepiped. This is due to the fact that most of the material Within the container 16 rests upon the trapezoidal side panel 24 of the container 16 which is lowermost during pouring therefrom as illustrated in FIGURE 3. The trapezoidal side panel 24 has a smaller portion adjacent the pouring spout than the portion thereof spaced from the pouring spout. Therefore, while material is being poured from the container 16, the material moves into a part of the container 16 adjacent the pouring spout which is smaller in volume than a part of the container 16 which is farther from the pouring spout. Thus, the center of gravity of the container 16 and the material therein does not shift greatly toward the pouring spout during pouring of the material. Therefore, the container 16 is readily handled and controlled during pouring therefrom.

It is to be understood that a container of this invention can be produced in any one of various shapes and configurations. The shape of the container of this invention depends upon the relative dimensions of the opposed side panels, such as the panels 20 and 22, and the relative dimensionsof the opposed side panels, such as the panels 2.4 and 26, in which the edges converge or diverge. The shape of a container of this invention also depends upon the shape of the side edges of the side panels of the container.

FIGURE 14 shows a blank 106 for construction of another container of this invention. The blank 106 has opposed side panels 108 and 109, which are similar in shape. The side panel 108 has side edges 110 which generally converge upwardly so that an upper edge 112 of the side panel 108 is shorter in length than a bottom edge 114 thereof. The side panel 109 has side edges 110 which generally converge downwardly so that an uper edge 114 of the side panel 109 is longer in length than a bottom edge 112 thereof.

The blank 106 also has opposed side panels 118 and 119. Each of the side panels 118 and 119 has curved side edges. The side panel 119 has a side edge 110 which coincides with a side edge 110 of the side panel 109. The side panel 119 also has a side edge 110 which coincides with a side edge 110 of the side panel 108. The side panel 118 has a side edge 110 which coincides with one of the side edges 110 of the side panel 108. The side panel 118 also has a side edge 120. Each of the side panels 118 and 119 has an upper edge 122 which is equal in length to a bottom edge 124 thereof.

The blank 106 is shown as having suitable upper flaps a FIGURES 5 and 6. A strip 129 extends along the side panel 109 for attachment to the side panel 118.

The blank 106 of FIGURE 14 may be formed into a container shown in FIGURE 15. The opposed side panels 118 and 119 of the container 130 curve inwardly while the opposed side panels 108 and 109 curve outwardly, as shown in FIGURE 15. However, one or both of the opposed side panels 118 and 119 may curve outwardly, rather than inwardly.

FIGURES 16 and 17 show a container which is formed from a blank 142 shown in FIGURE 18. The blank 142 has opposed side panels 144, each of which has opposed side edges 146 which curve one toward the other. The blank 142 also has opposed side panels 147, each of which has the mutual side edges 146 of the side panels 144. However, the opposed side edges 146 of the panels 147 curve one away from the other. Each of the side panels 144 has an upper edge 148 which is equal in length to a bottom edge 148. One of the side panels 147 has an upper edge 150- which is shorter in length than its bottom edge 152. The other side panel 147 has an upper edge 152 which is longer in length than its bottom edge 150. The opposed side edges 146 of one of the panels 147 converge upwardly and the opposed side edges of the other side panel 147 converge downwardly.

Suitable flaps are integrally arranged at the top and bottom of the side panels'144 and 147. FIGURE 19 shows a container of this invention. The container 190 has two opposed rectangular side panels 192 and two opposed side panels 194 which have converging edges 196. The converging edges 196 converge to a point 198. The side panels 192 are shown curved inwardly, but may curve outwardly.

The container 190 has a topcover 200- and a base 202. A pouring spout or aperture 204 is shown in the cover 200 for use if desired.

It is to be understood that a container of this invention is capable of withstanding relatively high external and/or internal pressures and forces without distortion or collapse. Furthermore, a container of this invention which has side portions which curve inwardly may be easily and readily manually grasped for handling thereof.

Although the preferred embodiment of the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
