His Afr'ys Mum United States Patent 3,443,685 CONTAINER CARRIER AND PACKAGE Herbert Jourdan Wanderer, Elmhurst, Ill., assignor to Illinois Tool Works Inc., Chicago, Ill., a corporation of Delaware Filed May 26, 1967, Ser. No. 641,537 Int. Cl. B65d 85/ 62 US. Cl. 206-65 8 Claims ABSTRACT OF THE DISCLOSURE A carrier device for articles consisting of a flap of perforated material having apertures of a predetermined size, which apertures are associated with a plurality of resilient webs or straps associated with the flap and traversing the aperture opening so that upon association of an article into mounted position within the aperture the web portions grippingly engage the article and prevent its retraction back through the aperture through which the article was first passed.

Background of the invention Field of the inventi0n.-The present invention relates to the multipackaging of products, principally in metal and glass cans, the final packaged product being referred to as a rnultipack. Several carrierdevices of the type which grippingly engage the product in the vicinity of their tops are presently being marketed and are referred to in the market place as the Hi-Cone carrier and the Clean Top multipack. The instant invention seeks to improve the type of carrier which presents a. perforated flap, but depends upon the measurement of the substantially uninterrupted margin of apertures formed therein to grippingly engage the product. Provision in the instant invention is made to provide readily expandable gripping portions to engage the can which has gripping formed abutment surface of sufficient lateral extend to prevent the can with the associated gripping portion from returning back through the aperture in which the canned product is mounted. It is noteworthy to realize that the instant invention is readily adapted to equipment now in the field and the application of they carrier device can be accomplished with facility by users of products presently being successfully commercialized.

Description of the prior art.There are a number of prior art references which show various types of multipackaging devices related to this invention; however, none of them have provided an engaging. element to grippingly engage an article associatedwith the character using a small degree of force which when finally mounted on the product prevents inadvertent removal of the product relative to the carrier body with which the engagingelements coact. Typical examples of prior art devices which the instant invention constitutes an improvement over are: U.S. Patent 2,487,109, US. Patent 2,874,835, US. Patent 3,199,908, each of which shows forms of carrier devices for use with a multiplicity of container products.

Also to be noted is theart cited in the above identified patents. In addition, applicant notes two patents which contemplate the use of web elements for container or containers to space a product from the side wall thereof. These patents are US. Patent 1,479,244 which is utilized in the egg carton business, and British Patent 386,182 (1933) which relates to a powder box device.

Summary of the invention The instant invention has as its object to provide a new form of carrier device which is engineered to facilitate insertion of a can into one of the pockets or aper- 3,443,685 Patented May 13, 1969 tures of the carrier, and additionally, engineered to facilitate its removal.

It is a further object of the invention to provide such a carrier device which is, in itself inexpensive, simple, and economical to produce as well as to assemble with canned products without the necessity of excessive modifications of equipment now in the field.

It is a further object of this invention to provide a carrier device for retaining a plurality of canned products together as a unit, which device requires relatively small forces to accomplish assembly of the canned product, as well as for removing the canned product for ultimate use, but which requires extraordinary force for accidental separation.

Yet another object of the invention is to provide a carrier device for retaining various shapes and configurations of product as a unit wherein each device is capable of only restrained movement relative to an adjacent device mounted in the same carrier.

Furthermore, it is an object of this invention to provide a carrier device which by virtue of its physical characteristics aggressively grips and embraces in intimate contact the wall of the product mounted therein.

Still another object of this invention, is to provide a carrier device for products which can be made using a flap of cardboard, plastic or other materials which can be perforated to make product receiving apertures and in conjunction therewith using either an integral or an elastic deformable element to provide the embracing and engaging forces which will be alluded to in greater detail in the specifications of this application and be apparent from a study of the drawings.

Other and further objects and advantages of the present invention will be apparent from the following description when studied in connection with accompanying drawings.

FIG. 12 shows variations of the carrier shown in FIGS. 1 and 2 of the drawings which are within the scope of the invention which I have disclosed.

Description of the preferred embodiments Referring now in greater particularity to the drawings, FIG. 1 portrays a carrier, receptacle, or retainer, in accordance with the principles of this invention comprising a fiat sheet of plastic material hereinafter identified by the numeral 20. The sheet is provided with a plurality of spaced apertures 22, preferably an even number such as 2, 4, 6, or 8. The apertures 22 are provided with a peripheral measurement having a predetermined peripheral configuration and measurement of the canned product with which the device is to be assembled. The carrier device is made of plastic material which is relatively resilient, flexible, and elastic, and which will not readily tear. Polyethylene is a preferred example of a suitable material, but other functionally similar mate rials are satisfactory. The retainer or carrier 20 preferably is stamped from an elongated strip of material in a suitable punch press, leaving integral strap or web portions 24(a), 24(b), and 24(0) which traverse the aperture opening 22. There may also be formed during the stamping operation, a plurality of additional apertures 26 which serve as handle means for the users fingers in the carrier after being assembled with adequate protection to facilitate its carrying. In this regard other forms of handle means, some of which are elements to be assembled to the carrier, can be provided which perhaps are best seen in already existing articles such as US. Patent No. 3,016,136 and US. Patent No. 2,997,169.

As has been noted, and as will be seen with particular reference to FIGS. 2 and 3, the diameter or configuration of the aperture 22 closely approximate the diameter or measurement of the canned product 28 to be associated with the carrier. The carrier 20 remains substantially flat as it has been placed down over the tops of the cans 28, preferably by machinery, not shown herein, while the straps or engaging means 24(a), 24(b), and 24(0) are moved outwardly and into an upright position as at 30 to provide an upright collar in intimate and embracing contact with the side wall of the container, and additionally, is positioned in overlying relationship to the peripheral margin 32 of the carrier aperature 22. The thickness of the material from which the straps 24(a), (b), and (c) are provided must be of sufficient measurement so that when in engaged position with the side wall of the canned product 28, it will extend laterally outwardly a suflicient distance to overlie the margin 32 of the carrier aperture thereby to resist the web portions and associated can product being pulled through the aperture by reason of the weight of product which it supports. This ovelap function, together with nature of engagement of the web portions 24(a), (b), and (c), are key features of this invention. Thus the deflected strap portions 24(a), (b), and (c) in engagement with the can side wall resists withdrawal of the can inadvertently relative to the carrier. The length of the strap elements 24(a), (b), and (c) and their positionment relative to the margin of the aperture 22 determine the axial force to which the can can be subjected relative to the carrier body 20, while the thickness of the carrier material and its chemical formulation determine the qualities of the carrier. The aforementioned elements can all be modified to afford any particular rigidity or other characteristic that might be desirable from the standpoint of the manufacturer and user. When made in accordance with this invention it is practically impossible thru inadvertant acts to remove a can by axial forces impressed on the cans relative to the carrier 20, while at the time the forces necessary to accomplish assembly of the carrier to the cans need not be very great.

In view of the foregoing, it will be appreciated that the cans and retainer are not readily separated inadvertently. However, when it is desired to remove a can from the carrier very little force need be exerted as the can may be removed by tilting it relative to the carrier, the can body 28 by reason of its length providing a suflicient lever arm to thereby apply sufiicient force to the strap portion which will ultimately be tilted and drawn down so that at least a portion of it is positioned belowthe plane of the carrier and ultimately will be stretched and disturbed so that removal of the container from the carrier is accomplished. Likewise I have found that the can is readily removed by lifting the can upwardly in a direction away from the overlying web portion 2 4(a), (b), and (C), relative to the carrier body 20 permitting the bottom of the can to be drawn through the engaging web portions with a relatively small force. The manner in which the webs 24(a), (b), and (c)embrace the carrier is clearly visible in FIG. 3 of the drawings. When three webs are provided the webs engage the substantial portion of the entire periphery of the can-the only portion not being engaged being in the vicinity of the juncture of two web portions with a margin of the aperture of the carrier 20. It will be appreciated that this can be eliminated by providing a short interconnecting web portion shown by dashed lines in FIG. 1 at the bottom left hand aperture where the web is designated by the numeral 34. The same phenomena as explained above can be seen in FIG. 5 where in the absence of provision for web 34 a short area of nonengagement is designated by the numeral 36.

With particular reference to FIGS. 2, 4 and 6, a second embodiment of the invention may be viewed. In this particular version of the invention I have shown a carrier 20(a) preferably made of stiff material such as paperboard and the like with apertures 22(a) being provided of predetermined size and configuration for the object to be mounted therein. Instead of integral webs 24 I have provided the carrier with elements 24(d), 24(e), and 24(1) which, as shown, is an elastic member, such as a rubber band, suitably stabbed or secured to the carrier at three or more points in the vicinity of the margin 32(a) of the aperture. These elements must be of suitable size in cross section so that upon insertion of a can element 28(a) or the like as viewed in FIG. 4 and FIG. 6, the can is embraced by the elements 24(d), 24(e), and 24(9) with the cross sectional configuration of the element totally overlying the clearance area between the wall of the aperture of the carrier and the side wall configuration of the container with an additional portion thereof resting atop the carrier surface 20(a). Various means of securing these elastic elements to the carrier can be utilized in addition to staples, another means for attachment of the element includes providing tabs struck up from the cardboard body as is clearly shown in dashed line in FIG. 2 at the lower left hand corner of the carrier where elements 38 have been shown in dashed line. These tabs when slightly bent up out of the place of the carrier body 20(a) could be used to hook a rubber band over them to rapidly position them in mounted position in the near vicinity of the margins of the apertures on the carrier body 20(a).

In FIG. 7 I have shown still another embodiment of the invention which is similar in many respects to the carrier device 20 shown in FIG. 1. In this configuration only a pair of web portions are shown transversing the aperture opening, the web portions being identified by the numerals 24(g) and 24(h). These web portions would function in much the same fashion as the web portions 24(a), 24(b), and 24(0) in FIG. 1, giving embracing action for a substantial portion of periphery of the container with the accompanying interference fit as a result of the thickness of the material being so selected to be greater in thickness dimension than the clearance of space between the object to be mounted in the aperture 22(b) and the margin of same. Suitable handle means would be provided-I have shown these as punched apertures 26(b) having push down flaps 40(b) to provide a folded margin to eliminate sharp edges that would normally come in contact with the fingers of the user. Such a form of handle means is particularly useful where the product to be carried by the carrier is of substantial weight and the carrier body is made of relatively thin material.

In FIG. 8 a modified embodiment of the carrier shown in FIG. 2 is designated by the numeral 20(0). In this particular version a different configuration of resilient engaging element 24(1') is shown to illustrate the fact that various configurations of engaging elements may be employed. It is noteworthy that the greater number of segments or elements overlying the aperture that are afiixed in the vicinity of the margin of the carrier, the greater the extent of circumferential engagement of the wall surface object to be secured will be.

In FIGS. 9, 10 and 11, I have shown a third embodiment of the invention consisting of a carrier body 20(d) of similar con-figuration to carrier 22(a) in FIG. 2, but having instead of chordal segments of an engaging member presented, this embodiment presents a series of tablike elements 42 which can be placed strategically about the peripheral margin of the aperture 22(d), each comprising a body element 44 to be secured by adhesive or stapling to the body 20(d) of th carrier with an integral finger-like element 46 projecting into the aperture and presenting flexible engaging elements which can be distorted or flexed upwardly as the can product is inserted therein, after insertion of the fingers serving a similar purpose from a broad standpoint that resilient elements 22 (a) thru 22(i) perform in the previously described embodiments. It should be noted specifically that this particular form of the invention works most effectively with objects having a bead or other enlargement on its side wall so that it can underly the bead and perform a locking function. -I have noted that with light weight objects the periphery bead on the container or other object is unnecessary if these fingers are of sufiicient rigidity to grippingly impinge upon or engage the object. -It is possible to coat these fingers with material which will cause the finger-like engaging elements to adhere to the wall of the mounted element and resist axial movement of the product mounted therein if this is found desirable. It should be pointed out as has been mentioned in the description of other embodiments that the thickness of these portions are preferably of sufficient thickness to exceed the dimension of the void between the object mounted in the aperture 22(d) and the margin 32(d) of the aperture 22(d). This gives the desired interference which in turn assures the user that the tab is incapable of being doubled back upon itself and pulled down through the aperture. Handle means, either separate or integral, are contemplated to be used with this device. I have shown an integral handle means 26(d) stamped to provide a semicircular opening with the other half of the circle bi-sected into two quarter segments of a circle identified by the numeral 46(d) which upon insertion of a users fingers will be deformed downwardly to provide 180 of folded edge to give a smooth surface of at least double the thickness of the sheet material to increase the apparent thickness of the material exposed to the users fingers.

Lastly, in FIG. 12 I have shown still another embodiment of the carrier which is identified as 20(e) This form of the invention consists of a carrier body having a piece of film 50(e) superimposed on the top surface of the carrier body 20(e) with portions of the film overlying the aperture 22(e), said overlapping portion being desig nated as 52(e). It is consistent with my invention that these overlapping portions be of different configuration than the configuration of aperture 22(e), so that upon insertion of a can product into the aperture 22(e) the over-lapping portion 52(e) will be spread laterally outwardly and axially upwardly and upon passage of the can through the opening it will be trapped against removal by inadvertance or gravity in the same mechanical fashion as that contemplated by the other carrier heretofore described.

The carrier herein disclosed is simple to associate with containers such as metallic and glass cans, or other objects suitable for multipackaging, to facilitate their handling. The package thus formed provides a stable unit which enhances the sale of multipackaged products, facilitates the storage of such products, does not obscure the side wall of the container from the purchasing public, does not obscure the side wall of the container from the purchasing public, does not impair the ability to chill the product where such is advantageous, and afiords assurance to the user handling it that products carried thereby will not be dropped from the carrier inadvertently.
