The hOIl which are to be read in conjunction therewith and in which zon al disposed panel 38 is located in vertically spaced like reference numerals are used to indicate like parts in relafiell t0 the frame 36 and rigidly Secured thereto by various views wherein: means of corner posts or braces 40.

It Wlll be noted from FIG. 4

FIG. 4 is a bottom plan enlarged view of the carrier shown in FIG. 3;

that the radius of the arcuate tabs 42 is somewhat less than the radius of the container beads so as not to con- .3 form to the curvature of the beads in order to provide a convergent lead-in guide channel 45 between the braces 40 and the convex surface portion of the tabs when the container is in its retained position.

As indicated in FIG. 7 the panel 33 is formed with an upstanding flange 46 whose upper horizontal edge surface 48 engages in supporting relation the underside 47 of the bead 16. The flange 46 is tapered outwardly at an angular relation of approximately 80 to the plane of the panel 38 so that it can be elastically pivoted to a substantially vertical position (FIG. 8) where it will provide suflicient clearance to allow downward movement of tab 42 to its location shown in FIG. 7. It will be noted that the sloped outer face of flange 46 does not bear against the container wall 22 in interlock position. The axial center of the panel 38 has formed therein an enlarged opening 49 providing a finger hole and the wall of the opening is preferably rolled over, as at 50, to avoid the forming of rough edges.

In order to allow entry of the head 16 into its retained position (FIG. 7) it can be seen that the vertical distance measured from the undersurface 43 to the upward facing edge 49 must be greater than the height of the bead 16 as measured from its lower most portion 47 to its upper extremity 54. There is no applicable vertical separation of the

surface

43 and 48 during container insertion can be seen from the particular construction of the

units

28, 30 wherein the frame 36 and panel 38 members are formed respectively with continuous tabs 42 and flanges 46 which act as stiffening ribs to prevent appreciable horizontal deflection of the members.

Assembly of the carrier onto the containers can thus only be completed by forcing the deformable flange 46 inwardly to a substantially vertical position (FIG. 8) by pivoting about its point of juncture with panel 38. The flange 46 is deformed to a location so that the central fiat portion 44 of tab 42 is free to move downwardly so as to be positioned below and inwardly of the head 16. As best seen in FIG. 4, the bead 16 is slid or directed into channel 45, with the outer portion of the bead 16 riding on the arcuate extremity of tab 42 until the pivoting of flange 46 allows downward movement of the tab.

To permit the carrier 12 to be readily positioned in interlocked relation with the containers, the faces 44 of rigid tabs 42 can be formed so as to slope toward the beads 16, as best shown in FIGS. 3 and 7. The diagonal edge configuration 52 results from the intersection of the vertical arcuate surface of the tab 42 with the face 44. Due to the fact that the carrier of the instant invention is relatively rigid, it has been determined that the carrier can be more easily rolled onto the container bead by first having the bead enter the channel 45 and be guided into its interlocked position by the curved portion of the tabs. The result is that the diagonal edge 52 permits a point contact at 54 during the initial bead engagement with the retaining tab so as to permit the upper edge 48 of flange 46 to move into contact with the underside of bead 16.

Once the tab face 44 is positioned in place behind the bead 16, the flange 46 is free to pivotally return to its static or unstressed position shown in FIG. 7 wherein the container is held against downward movement by the positioning of horizontal edge 48 beneath the bead 16. The function of the tabs is to act as a physical static barrier to prevent outward horizontal movement of the container. Contact between the posts 41) and the outer portion of bead 16 limits horizontal movement of the container in the direction of flange 46. Thus, by applicants novel arrangement the container is retained in a positive static interlocked manner without the use of resilient or elastic forces acting on the container.

Referring again to FIG. 7, it is seen from the relation of the carrier to the container that the container is held as distinguished from being gripped or resiliently retained. A space is maintained between the upper edge of the bead and the undersurface 43 of the planar frame 36 to allow relative movement between the containers and carrier. The retaining portions of the carrier are utilized to react against the container upon its movement, but by themselves, apply no resilient gripping action. Thus, the carrier of the instant invention provides a more secure package by allowing a certain amount of movement of the containers. When the package is dropped, or otherwise receives an impact, there will be less probability of the carrier failing to retain the containers as contrasted with clip carriers that employ resilient grips that could release if deflected.

FIG. 9 shows a perspective view of a modified carrier in position on a six-pack. This carrier member 60 differs from the carrier member shown in FIG. 1-8 in that extensions or wings are provided on each end of the carrier in the form of

units

62 and 63, which are one-half the

basic units

28 and 30 previously described. This embodiment combines the features of carrier 14 while providing additional support for the outermost containers so that each is retained at two portions of its head instead of just the inner containers as shown in FIG. 1.

The container carrier of the instant invention can be fabricated as an integral unit from a resilient sheet material by molding, by an injection mold process, or other standard fabrication means. It is preferably made from a plastic material, such as high-impact styrene, due to its low cost, but any suitable material, either metallic or non-metallic, is considered within the contemplation of the invention.

While it will be apparent that the preferred embodiment of the invention herein disclosed is well calculated to fulfill the objects above stated, it will be appreciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.

What I claim is:

1. A one-piece multiple container carrier for containers having an upwardly and laterally projecting bead at the upper end of the container, said carrier having for association with each container:

(a) an upper member extending across the top of the container,

(b) a rigid tab portion having an arcuate shaped surface integral with said upper member and depending therefrom to a location wherein said surface is symmetrically positioned in close proximity to the interior portion of the bead,

(c) said arcuate surface having a degree of curvature that is slightly greater than the degree of curvature of said bead wherein it provides a lead-in guide for the bead,

(d) a lower member connected in fixed spaced relation to said upper member for engaging the underside of the container bead.

2. In combination with four substantially identical cylindrical containers arranged in side-by-side substantially abutting and parallel relationship so as to provide a central space between the containers and each container having an upstanding and radically projecting peripheral bead around the top thereof, a unitary carrier for statically interlocking together the four containers, said carrier comprising:

(a) a pair of vertically spaced rigidly connected upper and lower horizontally disposed members,

(b) said upper member in the form of a generally square shaped open frame blank extending across the top of the four containers such that each corner of the frame is positioned respectively adjacent an area of substantial abutment of the containers,

(c) said frame having a generally square central opening the sides of which are located respectively over one container so as to define a chord of the container,

(d) four rigid tabs extending downwardly from said Fpper member and having inwardly facing planar aces,

(e) said tabs being positioned whereby said faces form respectively substantial downward continuations of the four sides of the square opening whereby the lateral extremities of each of said faces are in close proximity with the interior portion of the beading 5 of a container,

(f) said lower member in the form of a relatively square panel positioned in the space and having upstanding flanges integrally formed at the edges thereof, terminating in a generally upwardly facing edge for engagement with the underside of a container bead,

(g) all portions of said carrier other than said upstanding flanges being relatively rigid and said flanges to allow the beads to be moved into their static interlocked position with said carrier.

3. A carrier as recited in claim 2, in which:

(a) said rigid connections provide spaced stop means engageable with the exterior of each container head, said connections disposed to limit the movement of each container to a predetermined amount.
