7 Claims. (Cl. 206-65) This invention relates to containers and more particularly to a container for the shipping and handling of containers having one or more recessed ends such as cans containing foodstuffs and the like.

This application is a continuation of patent application Serial Number 207,103, filed January 22, 1951, now abandoned.

An outstanding object of this invention is the provision of a device which will hold a small number of such cans as a unit for ease in handling.

A further object of the instant invention is to furnish an attractive holder for the retail sale of canned goods.

An additional object of the present invention is the provision of a sheet-material container for a small group of canned goods, which container can be folded flat while not in use and yet can be quickly expanded to operative position.

A further object of this invention is the provision of a container for cans and the like that is made up from a single blank of sheet material and which can be made an assembled on automatic machinery.

An additional object of the invention is the provision of containers which will hold several cans in grouped relationship firmly and compactly and which is particularly useful in retail sales of canned goods, such as beer, oil, soup, and scouring powder.

Another object of the invention is the provision of a container for flanged or recessed cans which makes use of the flange or recess of the can to hold it securely in place in the container.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto.

The character of the invention, however, may be best understood by reference to certain of its structural forms as illustrated by the accompanying drawings in which:

Figure 1 is a perspective view of the container of the instant invention.

Like reference characters denote like parts in the several figures of the drawings.

As conducive to a better understanding of the invention, a recital of the prior art devices and the problems in the art is appropriate. It is the practice in the retail sale of canned goods to either sell a large quantity in a cardboard box or to sell small quantities in a loose I fashion, placing the cans in a bag along with the customers other purchases. In the sale of canned beer, for instance, the customer may purchase a carton containing, say, a dozen cans; however, if he wishes to make a small purchase, say three, the cans are usually placed in a bag. The placing of cans in a paper bag is particularly objectionable if they have been refrigerated and water has condensed on the surface of the cans; the usual thin paper bag becomes wet, breaks, and the cans fall out. The possibility of using a cardboard carrier of the type used in the sale of bottled soft drinks suggests itself, but the cost of such a carrier is often prohibitive in the sale of canned goods where the allowable margin of cost of distribution is very low. The present invention is intended to solve the problem thus presented.

One species of the container of the instant invention is shown in assembled condition in Figure 1. However, the invention will be more easily understood by starting with a description of the blank from which the container is formed.

Referring to Figure 2, which best shows the blank, the reference character 10 is used generally to designate the container. The container 10 is made up from a single sheet of material of elongated rectangular shape. The sheet is divided into five sections by

fold lines

16', 17, 18 and 19 running parallel with the ends of the rectangle. The fold line 16 and the end 31 define a glue tab 11. The score line 16 and the score line 17' define a bottom panel 12. The score line 17 and the score line 18 define a first side panel 13. The score line 18 and the score line 19 define a top panel 14. The score line 19 and the end 32 define a second side panel 15. The bottom panel 12 and the top panel 14 are approximately as wide, from score line to score line, as the diameter of the can with which the container is to be used. The first side panel 13 and the second side panel 15 are approximately as wide, from score line to score line or from score line to end, as the can is high. The length of all the panels or, rather, the width of the blank is considerably less than three times the diameter of a can and a little larger than twice the can diameter. Formed on the bottom panel 12 are two

lock tabs

20 and 21 which are formed by the use of cuts and fold lines, as will be further explained; these tabs are attached adjacent the ends of the panel and extend inwardly to Ward each other. The top panel 14 is also provided with

similar lock tabs

22 and 23. Lock tab 20 is similar to the others and will be described in detial. The tab 20 is defined by two

side cuts

25 and 26 near the end of the bottom panel 12 and parallel to the score lines 16 and 17'. The inner ends of the

side cuts

25 and 26 are joined by an arcuate cut 24 whose center of curvature is adjacent to the end of the panel and whose radius of curvature is approximately that of a can. The other, outer ends of the side cuts are joined by a score line 28 which is parallel to the side of the blank. The area defined by the

side cuts

25 and 26, the arcuate cut 24, and the score line 28 is traversed by a score line 27 which is parallel to score line 28 and which divides the area so defined into a major, free portion 29 adjacent to the arcuate cut 24 and a connecting portion 30 adjacent to the score line 28. All the

lock tabs

20, 21, 22 and 23 are made in this manner.

The assembly of the container is best understood by reference to Figure 1 which shows the condition of the container with the lock tabs folded out of their respective panels. The collapsed enclosure is formed by the manufacturer of the container and has panel 12 as its bottom, panel 14 as its top, and

panels

13 and 15 as its sides. The glue tab 11 will lie against the inside of the second side panel 15 adjacent to the end 32 of the blank and is glued or otherwise fastened thereagainst. Until the collapsed container is received by the person who is to insert the cans, presumably the canner, the lock tabs remain in the planes of their respective panels. Before the cans are inserted, the container is expanded and the lock tabs are pushed out of their respective panels and bent about their score lines so that the portions which correspond to the major, free portion 29 of tab are in a position more or less parallelto the panels from which they are formed and those portions which correspond to the connecting portion of tab 20 are bent back toward the panel and lie thereagainst.

In use, the container is in the condition shown in Figure 1 before the cans are inserted, with the exception that the tabs remain in the plane of the hand. Now, the most cans are made up of an elongated cylindrical tube, the ends of which are closed by circular end pieces made of the same material as the tube; the joint between the tube and the end pieces forms a flange that extends axially end-wise for an appreciable distance and forms a recess at the end of each can. A number of cans, three in the case of the preferred embodiment, are placed in the container. The middle can extends between the top and

bottom panels

14 and 12 and is situated in the space between the sets of lock tabs. The outer two cans also extend between the top and bottom panels, but they are situated partly within the container and partly without. The

lock tabs

20 and 22 are extended into the opposite recesses of one of these cans, while

lock tabs

21 and 23 are extended into the end recesses of the other of these cans. The resilience of the material from which the container is formed causes the lock tabs to be resiliently biased inwardly of the container. This means that when a locking tab, say tab 20, is inserted into the end recess of a can, the major free portion 29 will be against the end of the can at the bottom of the recess and the edge formed by the arcuate cut 24 will press firmly against the inside of the flange of the can and will tend to bias the can into the container. The size of the connecting portion 30 must be chosen for optimum performance with a given type of can. It can be seen that any tendency for the end cans to leave the container will be checked by the lock tabs and, of course, the middle can or cans will be held firmly between the outer cans. The container of the invention may be placed on groups of cansat the place where the cans are filled and packed in cartons for shipment ultimately to the retailer; on the other hand, the containers may be shipped fiat to the retailer, if desired, and the retailer may place the cans in them in the manner now practiced with paper bags.

A modification of the container of the invention is shown in Figures 3, 4 and 5. Figures 3 and 4 show the container in assembled, expanded condition with cans held assembled therein. A description of the blank will aid in an understanding of the device and, for that purpose, reference is made to Figure 5. The reference character generally designates the container of the invention. The container 40 is made up from a single sheet of material of elongated rectangular shape. This sheet is divided into five sections by

fold lines

46, 47, 48 and 49 running transversely thereof. The fold line 46 and the end 60 define a glue tab 41. The score line 46 and the score line 47 define a bottom panel 42. The score line 47 and the score line 48 define a first side panel 43. The score line 48 and the score line 49 define a top panel 44. The score line 49 and the end 59 define a second side panel 45. The dimensions of the panels are related to the dimensions of the particular can in the same manner as has been described above for the species shown in Figure l. Formed on the bottom panel 42 are two lock tabs 5'0 and 51 which are formed by the use of cuts and fold lines, as will be further explained; these tabs are attached more or less centrally of the panel and extend generally parallel to the sides of the blank. The top panel 44 is also provided with

similar lock tabs

52 and 53. Lock tab 53 is similar to the others and will be described in detail. The tab 53 is defined by a semicircular cut 54 and a score line 55 which is situated at the base of the semi-circle. The score line 55 is situated on a line running from side to side of the blank medially of the panel and is further situated a short distance from a line running longitudinally of the blank medially of the panel. However, where tab 53 lies on one side of the line, running from side to side of the blank medially of the panel, the tab 52 lies on the other side and the other pair of

tabs

56 and 51 are also related in that manner. The area defined by the semi-circular cut 54 and the score line 55 is traversed by a score line 5-6 which divides the area so defined into a free portion 57 and a connecting portion 58. The score line 56 traverses the tab area in such a way as to make the connecting portion 58 of a generally wedge shape with the small end of the wedge at the portion of the tab area which is closest to the sides of the blank; in other words, the connecting portions of the

tabs

52 and 53 are both wedge-shaped and the larger ends of the wedges are adjacent to each other. The details of the relationship between the

tabs

50 and 51 are exactly the same as in the case of

tabs

52 and 53. The assembly of the blank by the manufacturer involves the gluing of the glue tab 41 to the panel 45 adjacent to the end 59; for that purpose, it is usual to bend the hand 42 about the score line 47 and the

panels

44 and 45 about the fold line 49. The container in this condition is fiat and may be easily shipped. The person who places the cans in the container expands the flat container described above into an open condition. After insertion the cans, he bends the tabs about their base score lines and again about their dividing score lines in such a manner that the connecting portion lies flat against the portion of its respective panel which is on the other side of the base score line from the said connecting portion and the free portion is parallel to and spaced from the panel. If a can tends to move outwardly of the container, the flange of the can butts against the downwardly-extending large end of the connecting member. The free portion of the tab, of course, serves to prevent the connecting portion from flipping back to its original position in the panel from which it was pressed. The condition of the container and cans is as shown in Figures 3 and 4. It is to be understood, also, that this type of tab could be used in a container constructed to hold three or more cans instead of two.

Another modification of the container of the invention is shown in Figures 6, 7 and 8. Figures 6 and 7 show the container in assembled, expanded condition with cans held assembled therein. A description of the blank will aid in an understanding of the device and, for that purpose, reference is made to Figure 8. The reference character designates the container of the invention. The container 70 is made up from a single sheet of material of elongated rectangular shape. This sheet is divided into five sections by

fold lines

76, 77, 78 and 79 running transversely thereof. The fold line 76 and the end 92 define a glue tab 71. The score line 76 and the score line 77 define a bottom panel 72. The score line 77 and the score line 78 define a first side panel 73. The score line 78 and the score line 79 define a top panel 74. The score line 79 and the end 93 define a second side panel 75. The dimensions of the panels are related to the dimensions of the particular can in the manner that has been described above for the other modifications. Formed on the bottom panel 72 are two

lock tabs

80 and 81 which are formed by the use of cuts and fold lines, as will be further explained; these tabs are attached more or less centrally of the panel and extend generally parallel to the sides of the blank. The top panel 74 is also provided with

similar lock tabs

82 and 83. Lock tab 83 is similar to the others and will be described in detail. The tab 83 is defined by an end cut 84, running transversely of the blank, a first side cut 87 running longitudinally of the blank, a score line 88 running transversely of the blank, and an irregular cut, the whole being of generally square configuration. The irregular cut is made up of an arcuate cut 85 and an arcuate cut 86 of similar radii of curvature. The centers of curvature of these two arcuate cuts are adjacent to the side of the blank. A fold line 91 runs across the tab, lies transversely of the blank, and passes through the point of intersection of the arcuate cuts 85 and 86. The fold line 91 divides the tab into a free portion 89 and a connecting portion 90. The score line 88 is situated on a line running from side to side of the blank medially of the panel and is further situated a short distance from a line running longitudinally of the blank medially of the panel. However, where tab 83 lies on one side of the first-mentioned medial line, the tab 82 lies on the other side; the other pair of

tabs

80 and 81 are so related. The assembly of the blank involves the gluing of the glue tab 71 to the panel 75 adjacent to the end 93; at that time the blank will be bent about the score line 77 and the score line 79 to produce a container which is flat for shipping. On placing the cans in the container, the flat container described above is expanded into open condition. After the cans are inserted, the tabs are bent inwardly of the container about their score lines which correspond to the score line 88 of tab 83 and, in the reverse direction, about the dividing score line corresponding to score line 91 of tab 83. The connecting portions then he in contact with their respective panels and the free portions lie parallel to and spaced from said panels. This means that the free portion of the tab lies against the end of the can and the connecting portion lies between the tree portion and its panel. The arcuate cuts 85 and 86 lie along the inside of the flange of the can and the tab locks the can against removal from the container. The condition of the container and cans at this point is best shown in Figures 6 and 7. Of course, this type of container can be modified slightly to hold three or more cans as well as the two shown.

Although the container is necessarily made of sheet material, this sheet material may be paperboard or the like or even sheet metal, such as aluminum. The particular material will be selected to fit the particular situation in which the container is to be used. The outer surface of the container is, of course, an excellent medium for display and advertising.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit thereof. It is not, however, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such forms as properly come within the scope of the appended claims.
