METHOD AND APRARATUS FOR PACKAGING CANS AND BOTTLES IN CARRIER CARTONS Filed Nov. 30, 1951 3 Sheets-Sheet 3 I United States Patent METHOD AND APPARATUS FOR PACKAGING CANS AND BOTTLES INCARRIER CARTONS Arthur J. Murray, Minneapolis, Minn. Application November 30, 1951, Serial No. 259,156

12 Claims. (Cl. 53-7) This invention relates to the art of packaging articles such as cans and bottles and particularly to the packaging of such articles economically at bottling plants and canneries into compact carrier cartons arranged in two contiguous, short rows.

It is an object of my present invention to provide a highly efficient method and novel apparatus for quickly and economically packaging two rows of symmetrical articles in such manner as to form a protective carrier carton from the packaging material.

At the present time, bottling companies, breweries and certain canneries are supplying carrier cartons often m collapsed form to be set up and compactly filled with usually two short rows of cans or bottles for convenience to the purchaser. In some instances, the cantons in collapsed form are made available to the franchised bottlers who pay for the same, assemble the cartons and after assembly, fill the same with the bottles or pthei; articles.

In some instances, the canneries, breweries or bottlers make and assemble their own carrier packages, but in all cases known to applicant, the carrier carton is first formed and assembled and thereafter, the articles are disposed therein in two contiguous rows. The production of such carrier cartons and the labor required to assemble the cartons and thereafter fill the same, has been very expensive to the manufacturer or distributor, particularly when it is realized that the actual goods sold in such carrier packages command no higher price than that of the goods when sold without packaging. Most carrier cartons now utilized, while constructed for the most part of cardboard or analogous, relatively cheap material, require gluing of parts and flaps or fastening of interconnected parts by staples or other fasteners, thereby adding to the labor and expense of production.

In my co-pending application Serial Number 259,155, filed November 30, 1951, and entitled "Carrier for Canned or Bottled Goods, I disclose in several forms, an improved carrier. carton constructed. at low cost from a single, elongated sheet or strip of material having straight, elongated edges and scored and recessed in parts along transverse lines only, to encompass, reinforce, and divide two short, contiguous rows of articles and to also integrally provide a reinforced handle which when used, tightens the encompassing portions of the carton.

The instant invention is particularly concerned with the provision of a simple method and apparatus for simultaneously wrapping the two series of articles while forming the carrier carton for the same. Such a method makes available at the bottling plant or cannery, continuous packaging of the bottles or cans after they emerge from the dispensing and filling machines and are labeled without requiring separate labor to assemble and secure the parts of a carrier and to thereafter arrange the articles in such carriers.

More specifically, it is an object of my present invention to provide a method of packaging articles of the class described which consists in first transversely bending and positioning the central portion of an elongated, prefhaving the articles.

thereafter folding the remainder of the carton blank or strip to encompass the outer, bottom and inner surfaces of the articles and to divide the two rows, thereby reinforcing the structure, with provision of reinforced carrier handle at the extremities .of the integral strip, which handle is projected through the central portion of the strip and when the package is inverted to righted position, projects from the top and center of the package formed.

In carrying out of my improved and novel method I prefer to employ simple but highly eflicient apparatus which is particularly adapted for high capacity commercial use to assist in the bending and channel-forming steps of the treatment of the strip or carton blank and to further hold the blank in the channeled form and to facilitate the tipping and guiding of sets of the articles into proper positioning within the channels for subsequent encompassing of the articles by the outer end portions of the continuous strip. One of the essential parts of my apparatus is a jig or form or preferably a plurality of interconnected jigs having a cross sectional shape in the form of a W, thereby providing a pair of contiguous V-shaped, blank-supporting and article-receiving channels. With such a series of jigs or forms, the other parts of my apparatus are cooperatively related thereto to bring into juxtaposition at proper times in the cycle of operation, two sets or rows of upstanding articles with the rows immediately parallel to the longitudinal outer edges of the forms whereby through manually operated or auto matically actuated mechanism, a predetermined number of articles from each row may be tipped inwardly and guided to fall and slide into the two contiguous V-shaped channels and whereafter, by manual or automatic operation, the ends of the carton blank may be folded inwardly about the tipped articles to encompass the same and to. complete'the carrier package.

important-additional objecttherefore, is the provision of simple and eflicient apparatus which is particularly well adapted among other media for carrying out my new packaging method.

The foregoing and other objects and advantages of I my invention and improvements will be more apparent continuous,

erably pre-scored packaging strip to produce a pair of from the following description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and in which:

Fig. 11 is a perspective view of my fimshed modified carton in upright position.

Referring now particularly to the drawings, the packaging stn'p or blank which is used in my method and in conjunction with my apparatus for packaging articles for carrier purposes, is shown generally at 10 n Fig. 7. The strip or blank 10 has elongated parallel sides 11 and 12 which are continuous and parallel, having no side fiaps nor integrally formed members extending outwardly therefrom. The ends of the strip or blank terminate in tabs or diminished end portions 13 which are adapted to be used as handles of the finished carton containing the articles as shown in Fig. 6. The strip or blank 10, since it forms the subject matter for a co-pending application, will not be described in complete detail but it should be pointed out that there is a central fold line 14 which has means such as an opening or elongated slot 15 at the central part thereof for the purpose of passing the diminished end portions 13 theretlirough to form the carton as illustrated in Fig. 6. Oppositely disposed fold lines 16 define the juncture between the top portion 17 of the carton illustrated in Fig. 6 and the side portions 18 which are adapted to extend downwardly and engage the outer periphery of articles 25 placed in two short, contiguous rows therein. In a similar manner. fold lines 19 connect the side portions 18 with bottom portions 20 and fold lines 21 form the juncture for the bottom portions 20 and the separator or inner side portions 22 which in turn terminate in the diminished end portions 13 as previously described. Associated with some of the fold lines such as at 19 are openings 23 formed from slits or cut lines in the blank 10 which are adapted to receive, and the marginal edges thereof to engage, certain protruding portions of articles at the outer surface thereof as at 24 in Fig. 6 whereby such articles as capped cans 25 may thereby be positioned and retained against accidental lateral displacement from the open ends of carton 10.

The apparatus which I have devised for placing articles into the previously described strip or blank 10 comprises mechanism for advancing a large number of articles such as cans or bottles in filled and labeled condition to a point adjacent the prepared strip or blank 10 and tipping in predetermined and corresponding small numbers of the articles into proper position for completing the packaging operation to form an encased package for carrier purposes as illustrated in Fig. 6.

In order to maintain and support the single strip or blank 10 in the proper article receiving position I may employ a jig, or preferably a plurality of jigs or forms as shown in Fig. l. The jig or form 30 may take various dimensions and arrangement of parts but has, as an essential element thereof, an apex 31 shown in cross section in Fig. 2. Since it is an important function of my apparatus that the diminished end or tab portions 13 of the carrier strip or blank be allowed to pass through the slot 15 while the strip or blank still remains in contact with the apex element 3l I provide therein a corresponding slot or opening 32 which allows the tab portions to pass freely therethrough. In order to condense the relatively wide blank I0 I prefer to fold the end portion of the strip in a depending manner as shown in Fig. 2. To facilitate the support of the blank 10 in this position I may provide my form or jig 30 with walls 33 which form, with the central apex 3 1 and the downwardly disposed sides 34, a pair of contiguous V- shaped article-receiving channels when the strip It? is bent and placed as shown in Fig. 2. Where my strip is equipped with openings 26 as shown in Fig. 7 for receiving cans 25 which have upstanding neck and cap portions 27 I also provide the jig 30 with openings 35 to correspond and align therewith. It is understood that I may provide 10 slidably advanced therealongbut prefer to arrange in my apparatus a plurality of jigs 30 which are adapted to have blanks or strips 10 placed consecutively in each of them. When so arranged the jig 30 may be equipped with sides 36 as shown in Figs. 1 and 2 for the purpose of rigidly maintaining the strip 10 against misalignment or lateral movement with respect to the surface of the jig. For the purpose of bringing the jig 30, together with a blank 10 disposed therein, into juxtaposition with the articles to be packaged I may mount a plurality of the jigs 30 in spaced orderly relation for relative movement with the articles so that at the proper instant two short rows of said articles may be substantially simultaneously tipped into their proper respective positions into the jig 30 supporting the prepared blank 10. It will be obvious from the drawings that the weight of the cans in their tipped position will assist in bending and maintaining said blank in properly formed position within the jig. In order to advance the jigs to their proper position I may use such means as chain elements 37 which may be guided over a fixed structure or track elements and driven by such means as sprocket wheels mounted on a driving shaft journaled across the line of movement of the chains 37. The latter structure and mechanism is well known in mechanical science and is not shown herein.

Traveling in close parallel relation at each side of the jigs 30 mounted on their chains or belts 37 are additional traveling or advancing means such as belts 38 for carrying articles 25 in close upstanding relation. The belt 38 and the chains 37 may advance intermittently and at different rates of speed, the only requisite being a simultaneous positioning of a predetermined short row of symmetrical articles at both sides of a properly positioned jig 30 bearing a packaging strip 10. Such arrangement is shown in Fig. l with a jig and strip 10 in proper position for the said rows to be tipped thereinto by a tipping mechanism attached to a fixed framework 40. The tipping mechanism may take various shapes and forms and can even be eliminated where simplified machinery is utilized in conjunction with manual operation. In such case the operator would merely tip the required number of articles by hand into the jig and strip. Where it is desired to tip the articles mechanically, swinging arms 41 may be pivoted to a supporting structure 42 for simultaneous inward swinging to the dotted line position shown in Fig. 4 and back to the full line position therein. The arms 41 may be actuated by a toggle arrangement operating pivotally about a point 43 which may comprise a shaft fixed to and driving the cross arm 44. Pivotally interconnecting the ends of cross arms 44 with the tipping arms 41 are rods 45. The contacting portion of the tipping mechanism may be disposed across pairs of arms 41 at their lower ends as at 46. When thus actuated the contacting rods 46 will simultaneously tip the articles 25 inwardly to engage guiding means 47 which may comprise a strap or rod having bent portions at the corresponding position for each article to be guided and positioned thereover as they are being tilted inwardly. The guide rod 47 may be fastened to aportion of the fixed structure supporting the packaging equipment as at 48. Details of the guiding arrangement are shown in Fig. 3. It is understood, of course, that guiding mechanism could be associated with the contacting members 46 or could be otherwise disposed to move forwardly in contacting relation with the articles as they are being tipped into the jig 30.and then could subsequently be removed in order not to interfere with the progressive and successive packaging operation. I prefer, however, to use the rod 47 as shown since there is no moving mechanism associated with the guiding elements and the positions of the bent cradling portions are such as to cooperate with the articles 25 as they are being tipped over, thereby causing them to fall into the proper predetermined position with respect to the blank and its cooperating portions. For the purpose of holding the depending ends of the blank 10 out of the way of moving machinery portions I may employ retaining bars 50 as shown in Figs. 1 and 4. The retaining bars may have flared ends 51 adapted to press inwardly and retain the blank ends in depending relation and likewise retain the bent portions within the jig or form 30 as it is advancing along the machine.

Operation continuous slots and walls in a stationary jig with the strip position a strip or blank 10 over the form or jig 30 as position shown in shown in Fig. 1 as it is entering the guide bars 50 at the flared ends 51. As the jig advances by forward movement of the chains 37 in the direction of the arrow from the first position to the second position the depending .ends of the packaging strip are frictionally retained in the Fig. 2. As each jig 30 together with its packaging strip 10 advances, preferably in an intermittent manner, to the third position shown in Fig. 1 it is then in article-receiving position for tipping of two short predetermined rows of articles thereinto. The moving elements such as belts 38 likewise may advance intermittently in such a manner as to simultaneously advance the required number of articles to form a new short row for each jig and carrier strip positioned atthe tipping mechanism as shown in Fig. 1. At this point the tipping mechanism is actuated to the dotted line position in Fig. 4 and the articles are caused to rock over the guide rod 47 and fall into the required position as shown in dotted lines in Figs. 1 and 4. As the jig again advances together with its blank 10 and the articles 25 therein to the fourth position shown in Fig. l the depending ends of the blank are no longer retained by fixed guiding elements 50 and are clear of the advancing elements 38 which may be terminated or have their directional movements reversed as by passing over a pulley (not shown) positioned immediately beyond the tipping mechanism. The articles in the jig are then in the fourth position shown in Fig. 1 and the prescored end portions of the blank 10 then are bent around the articles 25 to closely encompass them and the diminished tabs or end portions 13 can then be introduced through slot 15 in the packaging strip 10 and through the cooperating slot 32 at the apex 31 of the jig 30. It is understood, of course, that the encompassing step in my packaging operation may be accomplished by suitable automatic or semi-automatic equipment or may be accomplished by manual operation. Details of the insertion of the diminished portion 13 through the slotted opening 15 in the packaging strip 10 is shown in detail in Fig. 5. Following this step the package is in completely assembled form and when inverted takes the form shown in Fig. 6 with the break at the central fold line 14 again being straightened to form a plane top surface with the diminished tabs 13 extending as handles for the'carton carrier.

An important feature of my packaging method and apparatus is the simplified operation required to construct the finished carrier carton together with the articles contained therein. Since all the fold lines in my packaging strip are parallel to the continuous elongated straight edges thereof, there being no laterally extending flat or integral portions thereof, allmovements and motions actively contacting the articles or the packaging strip are lateral to the said fold lines. Thus the articles may be simultaneously tipped into the jig and againstthe folded packaging strip 10 in a single simultaneous movement lateral to the direction of advancement of each jig unit and likewise the encompassing and folding operation may be a single movement lateral to the same intermittent line of travel to cause the articles to be completely packaged with handle element formed therein and the articles secured against lateral displacement, all without a sequence of various movements in different directions such as for folding flaps, gluing margins, and so forth.

Where it is desired to economize on material used in forming the carton the modified blank or strip 60 shown in Fig. 8 may be employed. This blank has no diminished end portions and utilizes a gluing operation in order to seal the encompassed sides of the carton in its finished condition. The modification is extremely simple in structure and is similar to the formof blank 10 in its intermediate portions including the top section and side sections. Likewise the bottom fold lines 61 and 62 are designed to cooperate with the bottom surface edges of the canned or bottled goods retained therein and have the openings formed from slits or cut lines 63 and 64 to cooperate with protruding portions thereof in the same manner as in the alternate embodiment. The fold line 65, however, need not have openings since the end section 66 of the strip 60 is designed to be a partition common to both short rows of articles. The bottom portion 67 at the opposite end of the strip or blank 60 has no additional fold line at all since it is glued in a flat manner tothe cooperating bottom portion 68 lying between fold lines 65 and 61.

ratus in the same manner as disclosed in my preferred embodiment. In this case, however, I prefer to arrange my contiguous V-shaped channel portions shown in Fig. 9 so as to be pivotally mounted across end portions 71 by means of hinge elements 72 it being understood that the pivot 73 of the hinge 72 may extend at either side into the fixed sides 71. Stops such as pins 74 cooperate with the contiguous V-shaped elements 75 so as to limit the downward movement thereof and to assist in supporting the weight upon the hinges.

When using the modified form of strip or blank in my modified jig or form 69 the blank 60 is placed therein in the same manner as previously described. Articles may be placed in the jig containing the strip or blank 60 by manual or automatic means and then the contiguous V-shaped portions of the jig 69 may be swung upwardly about pivot 73 on hinges 72 so that the apex at the hinged portions is eliminated and the transverse center line 76 which, in the form shown in Fig. 9 need haveno slot associated therewith, will again be bent back to its original fiat or plane form so as to constitute the top of the carton. Before attaining this position the bottom 68 of the blank 60 is first bent over the row of articles 70 disposed at the left side as shown in Fig. 10 with the partition 66 bent downwardly to closely encompass the articles and then the end section 67 is bent over to contact a portion of the area 68. An .adhesive coating 77 may be placed upon the end portion 67 or the portion 68 so as to adhesively secure the contacting surfaces as shown in Fig.'10. A roller element 78 may then compress the adhesive joint so as to finish the packaging operation. Where the modified device is used in conjunction with automatic equipment the roller 78 may bepositioned in such a manner that the folded carton will pass over and in contact with it during its forward travel. When the jig 69 is returned to its original open position and the packaged carton is removed therefrom in'finished condition it has the appearance shown in Fig. 11. It should be noted that even though there are no handle portions to cooperate with the remainder of the carton there nevertheless will tend to be a similar augmented gripping or binding action if the rectangular configuration of the entire carton becomes slighly distorted. The protruding surface portions v79 which already cooperate with the openings produced at slit or cut lines 63 and 64 in the carton will thus be further forced into binding cooperation therewith to prevent accidental lateral displacement.

It may thus be seen that l have .provided a new method and apparatus therefor which may utilize a single, economical sheet of foldable material and may quickly and efiiciently package a large number of canned or bottled articles in a manner such that the packaging operation may be economically accomplished directly at the bottling plant or cannery. Since the number of mechanical moving parts and the number of sequences of operation have been minimized the cost and maintenance problems of such operation and apparatus as herein described will be surprisingly low.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of my invention. What I claim is:

short rows of symmetrical articles, which consists in prescoring an elongated continuous strip of bendable material such as cardboard along parallel fold lines spaced equidistant from a transverse center line to provide endengaging packaging'portions and, simultaneously therewith, outer side-engaging portions, preforming in said continuous strip two series of openable curved slits corresponding in number to the number of articles to be packaged, said slit portions being disposed in juxtaposition to at least one fold line at each side of said center line to engage protruding portions of the articles for the purpose of preventing lateral displacement in the package, depositing two spaced upstanding rows of the articles into end engagement with a portion of the strip between the transverse centra! line of said strip and said parallel fold lines and in so doing, retaining the stock of each side of said strip outwardly of said parallel fold lines in an angulated relation to said end-engaging packaging portions, flexing said strip transversely and centrally to form a central upwardly disposed bend in said strip with the respective rows of articles separated at their upper ends, bending and wrapping the outer extremities of the two ends of said strip inwardly with one end of said strip angularly bent again inwardly and downwardly between the upper ends of said two rows of articles and the other end overlying an area adjacent the first end, pressing the two rows of articles toward one another to close said separation and fastening said other end of the strip to an area adjacent the first end overlying the upper ends of said articles.

12. A method of packaging, for carrier purposes, two short rows of symmetrical articles, which consists in scoring an elongated continuous strip of bendable material such as cardboard along transversely disposed parallel fold lines to provide end-engaging packaging portions and, simultaneously therewith, outer side-engaging portions, preforming in said continuous strip two series of generally curved slits corresponding in position to at least a portion of the articles to be packaged, said slits being disposed adjacent said fold lines to define edges for engaging protrading portions of the articles to prevent lateral displacement thereof in the package, depositing two spaced upstanding rows of the articles into end engagement, each, with a portion of the strip between its transverse center line and one of the adjacent parallel fold lines, then subsequently bending and wrapping the outer ends of said strip first upwardly along said fold lines while utilizing the weight of the deposited rows of articles to bend and retain said outer side engaging portions in angular relation to the central portions of said strip and then wrapping the outer extremities of the ends of said strip inwardly and securing the same together to complete the package.
