Referring to the drawings in more detail, Fig. 1 shows the completed assembly of the parts that forms the carrier 4 as made ready for use to engage with a plurality of designated like containers 5 pre-arranged in two opposing rows and each container being registered in a relative position to be automatically inserted into the carrier, and when inserted each container being firmly secured therein by making contact with a combination of rigid and flexible retaining parts of the carrier 4. The parts comprising the carrier may be fabricated of any suitable sheet ma terial, however, the parts are preferably fabricated of aluminum sheet, for example 3s and/ or 52s alloy of suitable gauge thickness, or such other alloy that will providefiexing spring temper characteristic with quality hardness that will retain the fabricated shape of the parts formed thereof and thereby withstand rough handling of the carrier without damaging its utility requirements. To this end, the fabricated parts are economically fastened together in assembly relationship by use of any suitable resinous adhesive, such as isocyanate 0r epoxy resinous compound, and thereby avoid the necessity to otherwise employ localized intense heat upon wall portions of the assembly such as would be required if the parts thereof were brazed or welded together as by conventional practice which would anneal and soften the spring temper hardness required of the flex-acting parts and also set up warp forming stresses in the structure that would defeat the intended efliciency and useful purpose of the carrier. The type of sealed containers intended for use of the carrier are those having projecting top rims such as conventional cans. The container retaining means employed and upon which the design of the carrier is based provides a rigid flat right angular wall portion and the top wall portion thereof supports the shoulder edge portion of the container rim and the side wall portion bisects the body wall of the container transversely of its shoulder edge. This support means is further augmented by additional and novel spring active retaining means that holds each of the containers firmly against the rigid flat right angular wall portion of the carrier. The vertical wall portions and spring retaining means being opposed so that the containers are supported in any desired number of opposite and multiple pairs, each pair being secured in alternate holding relation with respect to the parts arranged for retaining them in the carrier.
The individual parts fabricated for the assembly of the carrier 4 illustrated in Fig. 1 consists of a first part 6 illustrated in Fig. 2 and showing an elongated flat surface channel shape body which constitutes the central body part of the carrier. This part may be formed of 2s or 3s aluminum sheet of suitable thickness and bent channel shape to provide a fiat top wall portion 7 and two opposed right angular flat side walls 8 that are parallel. The longitudinal corner edges 9 of the top and side walls being substantially sharp edged. The length of the part 6 is less than the overall length of a row of spaced containers intended for the carrier. Each side wall 8 is provided with a pair of opposed and longitudinally spaced offset wall portions constituting two transversely opposed pairs of louvers that are partially sheared from the walls 8 and being bent outwardly to provide a bottom wall portion 10 at right angles from the wall 8 and then upwardly to form the wall portion 11 facing parallel with the particular dependent side wall 8. The longitudinal sheared edge 12 of each louver is spaced downwardly of the sharp corner edges 9 in order to leave a substantial margin of the side wall 8 cross above the edge 12. These louvers are formed to provide retaining bottom base slots for the support of the second parts of the assembly illustrated in Figs. 3, 6 and 7. The opposed ends 13 of the part 6 are flat and square. The U-shape openings in the ends provide means for the support of third parts of the assembly illustrated in Figs. 4 and 5. A pair of longitudinally opposed holes 14 of desired shape and size are provided through the top wall 7, each hole being substantially central between each pair of the transversely opposed louvers. Three border surface portions of the side walls 8 adjacent each louver is provided with an application of suitable resinous adhesive designated by stippled dots 15 including other application upon the end surfaces 13 and on inner surface portions of the side walls 8 adjacent the ends thereof. This application is made just prior to the assembly of the parts thereupon. Alternatively, an application of the resinous material may be applied upon the surface portions of the parts to be assembled together. Prior to the assembly of fitted parts the side walls 8 of the part 6 are relatively flexible.
The second fabricated part 16 is illustrated in Figs. 3 and 6. This part for purposes of illustration is used in a total of four duplicates when assembling the carrier. The part is preferably made of 52s aluminum alloy sheet of desired thickness, or of any other alloy that will have similar spring flexing characteristics desired when shaped and heat treated to have the quality temper hardness required to maintain its originally arcuate shaped contour after being flexed by use of the carrier. The part 16 consists of a strip of said sheet bent to provide a flat vertical end wall portion 17 and two opposed arcuate shaped leg portions 18 transverse thereof. The integral bent corner of each leg being at right angles to the end wall 17 so that the inner surface of the corner portion of the wall 19 will project outwardly at ninety degrees therefrom and be in spaced relation to the outer extended arcuate portion of the leg 18. Each pair of opposed legs 18 constitutes two integral arcuate shaped concave spring active prongs convexly opposed to each other and having inwardly opposed flared ends. The outer ends of the prongs 18 terminate outwardly of the indicated center point taken of the radius b as shown in Fig. 3. The radius bend a of each prong is substantially equal to the radius b which denotes the body radius of a container intended for the carrier. Upon the assembly of the carrier the base end wall portion 17 of each pair of the prongs 18 is arranged to flatly engage upon marginal portions of the side walls 8 of the part 6. The radius a of each prong is therefore taken from an eccentric center that is offset inwardly and upwardly of the center point taken for the radius b in order to initially position the arcuate shaped portion of each prong in proper register to exert firm clamping power when opposed by the engaging body portion of containers. The potential clamping power of each pair of prongs is augmented by the novel arrangement provided for the fulcrum pivot of each single prong leg that is projected outwardly and transverse of its base end wall 17. The depth of each prong wall portion 18 is greater than the end wall portion 17 as illustrated in Fig. 6, the cross section being taken along line 66 of Fig. 3, so that the bottom end of the wall 17 is adapted to engage upon the bottom wall portion 10 formed in the louvers of part 6 when being assembed together as shown in Fig. 7 illustrating the assembly of a duplicate part 16. The top edge surfaces 20 of the part 16 are uniformly flat and coplanar in relationship so that these surfaces 20 will be coplanar in relationship with the surface of the top wall 7 of the part 6 when assembled. The inner opposed surfaces 19 of the part 16 as shown in Figs. 3 and 6 are adapted to flatly engage in abutment upon the opposed end edge surface portions of the offset louver wall 11 of the part 6 when assembled therewith as shown in Fig. 7 illustrating the part 6 taken in cross section along line 7-7 of Fig. 2, and a duplicate part 16 taken in cross section along line 66 of Fig. 3.
The third part 22 to be used in duplicate to constitute one pair is illustrated in Figs. 4 and 5 and consists of a bent strip of sheet comparable to the material used in making the part 16 hereinbefore described and shown in Fig. 3. In part 22 (Fig. 4) there is formed a bent loop portion 23 having two opposed flat wall portions 24 that may be spaced apart so that the outer surfaces of the looped walls will be coincident with the inner opposed surface portions of the walls 8 of the part 6 adjacent the ends 13 thereof. Lower corner ends of the opposing walls 24 are each bent outwardly at right angles thereof to provide a pair of flatly opposed wall portions 25 that blend with a pair of longitudinally opposed projected arcuate bent prongs 26, each prong having an arcuate curvature of projected length coincident with the prong of the part 16 as hereinbefore described with respect to the radii a and b respectively. The top edge surfaces 27 of the flat wall portions 25 and the prongs 26 are coplanar in relationship as shown in Fig. 5. The top of the looped wall portions 24 is spaced downwardly of the top edges 27. The vertical depth of the prong walls 26 is greater than the depth of the wall portions 24 because a bottom central portion 28 of the flat wall portions 25 is spaced upwardly of the bottom longitudinal edges of the opposing prongs 26. The purpose being to expose a lower slot portion of the part 6 at each end portion thereof when the carrieris assembled that may be utilized to fit upon a slide bar to center the carrier for loading purposes if desired.
A modification of the part 22 is illustrated in Figs. 4a and 5a whereby the part 30 may be made in two halves if desired and be suitably fastened together upon the matching surfaces of the wall portions 31 to be substantially identical in the shape of the part 22. A further modification is shown of an offset raised portion 32 that may be formed to the arcuate prong leg 29 to provide a sectional rim portion upon the top edge 33 of the part 30 or the part 22. This rim section may either be formed integral as shown or be separately attached upon the part 30 in any suitable manner to provide a facility in the assembled carrier to arrest longitudinal movement of empty or loaded carriers when being stacked upon each other similar to the manner shown in Figs. 9 and 13 respectively.
The fourth part 34 is shown in Fig. 8 and consists of a U-shape bent wire rod of round or square cross section to constitute a retractable handle bar 35 for assembly into the carrier. The opposed projections 36 of the handle bar are openly spaced to be coincident with the spaced holes 14 provided in the part 6. These projections 36 are inserted into the holes 14 and the ends thereof are then bent at substantially right angles to be about parallel with the top wall portion 7 of the part 6 and thereby prevent any possible disengagement of the handle from the carrier. The part 34 when retracted will dispose the handle bar portion 35 upon the flat wall 7 of the part 6 as shown in Figs. 1 and 9, and to be utilized for novel purpose hereinafter to be described.
Further assembly of the carrier as shown completed in Fig. 1 consists of placing each of four duplicate parts 16 into each louver provided in the side walls 8 of the part 6 so that the outer surface portions of the end wall 17 will flatly engage upon the resinous adhesive coated surface portions of the side walls 8. The top surface of edges 20 of the parts 16 are disposed in coplanar relation with the surface of the top wall portion 7 of the part 6 as shown in Fig. 7. This coplanar relationship is accomplished'by the bottom edge surface of the central vertical wall portion 17 being engaged upon the horizontal face of the offsetting flat wall portion 10 of each louver. The outer opposed surface portions of the end wall 17 are entended downwardly coincident with the depth of the side walls 8. The wall portion 11 of each louver is spaced outwardly of the side wall 8 so that the inserted central end wall portion 17 of the part 16 will wedge against the pre-applied resinous adhesive 15 disposed upon the exterior surface portions of the side walls 8. Each assembled part 16 is firmly locked against longitudinal movement by its engagement with the opposed ends of the offset louver wall portions 10 and 11 that inwardly engage with the opposed right angular bent wall portions 19 adjacent the opposed pair-of the projecting spring active prongs 18of each part.
'The next and final step taken in the assembly of parts consists of inserting the looped wall portions 23-24 of each of two parts 22 into each open end 13 of the part 6 thereby making the side walls 8 thereof rigid. Each looped end of the part 22 is wedged into the open ends 13 and upon the pre-applied adhesive 15 and without spreading the side walls 8 out of parallel. The coated face of the ends 13 are flatly engaged with the right angular bent wall portions 25 of the part 22 so that the flat top surface of the edges 27 thereof at each end of the part 6 are disposed in coplanar relation with the top surface of the wall 7 thereof. Hence, all of the assembled parts 16 and 22 have their respective top surface edges disposed in uniform coplanar surface relationship with the top of the wall 7 that is disposed longitudinally central of the spring active parts. The assembled carrier is then subjected to a uniform oven heat to cure the resinous adhesive which firmly unites the parts together without drawing the temper out of the spring active prongs of the assembled parts nor cause the structure of the carrier to warp or distort in any manner that may other wise unduly set up unequal stresses in the structure. Hence, by making use of the resinous type of adhesive such unequal stresses in the metal parts can not take place, stresses are neutral when curing the resinous material to combine the parts together.
Upon completion of the portable carrier 4 as shown in Fig. 1 when made of aluminum, it may be anodized in various selective colors desired. For example the color can be gold, silver, jade including any other color that will be in harmony with the color decoration on the containers intended for assembly into the carrier. By being anodized the selected color will be etched into the surfaces of the carrier and will not deteriorate,-scufi nor will the aluminum corrode under any reasonable conditions to which the carrier may become subjected, thus making the portable carrier distinctly attractive for display of the particular group of containers retaine therein.
The portable carrier 4 as assembled is provided with a longitudinal central rigid part 6 having a flat top wall surface and two opposed vertical side wall surfaces. These wall surfaces converge at relatively sharp right angle corners 9 extending parallel with each other and across the base forming ends of the three opposite pair of pocket forming spring active prongs arranged at substantially right angles with respect to the side walls. 8 having these sharp corner edges 9. Each pocket is formed of the prongs being positioned from left to right as shown in Fig. 1 and described as follows: a first pair of oppositely disposed pockets 0 are formed of the left side prongs 26 of the part 22 having its concavity portions facing the concavities of the left side prongs 18 of the parts 16. The second pair of oppositely disposed pockets d are formed of the right side prongs 18 integral with the left opposing prong portions that is the right side of the pockets 0 and the left side prong 18 of the oppositely disposed parts 16, the concavities being disposed in facing relationship. The third pair of the oppositely disposed pockets e are formed of the right side prongs 18 of the second pair of parts 16 and the prongs 26 of the right end part 22, the concavities being disposed in facing relationship. Hence, each of the left and right arcuate shaped prongs that forms each container holding pocket in the carrier is freely independent of each other with respect to its flexible clamping action when engaging with containers. Therefore, each prong member when being resisted by the container will be independently free to flexibly oscillate from a fixed corner end thereof that is firmly united upon the particular wall portion of the rigid part member 6 of the carrier and being reinforced by the abutted ends of the louver walls 11 and the end faces 13 of the body part 6. Each arcuate shaped prong 18 and 26 is projected so that its arcuate portion is disposed less than ninety degrees in the radius of a complete circle. Therefore the power of each spring active prong when resistedby the engaging container will yield outwardly of its normal position but with enhanced spring resistance that will exert afirm grip upon the body of the container when inserted into the hereinbefore described pockets cde of the carrier.
The carriers 4 may be stacked in bundle form as illustrated in Fig. 9 showing two carriers together and portions thereofshown in cross section taken along line 9-9 of Fig. 1. The top and bottom edges of each carrier are uniformly flat and level, therefore any desired number of carrier units may be stacked upon each other and be strapped together in any suitable manner to be handled for storage and transportation purposes. The handle bar 35 of each unit is in retracted position and fits into a slot 28 (Fig. 9) that remains in the bottom of the rigid part 6. The handle bar portion 35 therefore serves to substantially lock each alternate carrier against any movement side-wise and is arranged to permit the top and bottom flat edges of each alternate carrier to flatly meet together, each upon the other. This alignment facility of stacked carriers serves to protect the arcuate prong members thereof from being damaged during handling for storage and transportation.
To load the carrier with like containers, the carrier 4 shown in Fig. 1 may be placed in an elevated registered position and centrally between two oppositely disposed rows of like containers 5 (Fig. 1) and positioned upon their bottom ends. The containers are spaced to be in central transverse alignment with each opposing pair of receiving pockets cde of the positioned carrier. For an example, each row of containers 5 while being conveyed upon a belt may be plowed or pushed inwardly to ward each other as shown by the arrows in Fig. l. The spring active prongs 18 and 26 when opposed will yield outwardly by the thrust imposed by each container upon being inserted until the full diameter of the body thereof passes inwardly of the outwardly flared terminal ends of the prongs, after which they close inwardly and strongly clamp upon the body of each container. The rigid and flat vertical wall portions 8 that forms the transverse base ends of each clamping pocket arrests the inward movement of each inserted container. The spring clamping action of the prongs 18 and 26 directs the container bodies into firm contact upon the corresponding portions of the rigid walls 8 so that a small portion of the top rim edge of the containers are flatly and squarely seated upon the corresponding surfaces of the top wall 7. Such engagement of the containers is further augmented for support by the top surface edges and 27 of the clamping prongs 18 and 26 that support portions of the top rim shoulder edges of the containers in accordance with the illustrations given in Figs. 10, 11 and 12 of the drawings and showing the compact loaded carrier.
As above described, the contact of each container body and rim portion thereof upon a coincident portion of the rigid member 6 of the carrier constitutes a hook-like firm supporting means that is provided for augmenting the support of the inserted containers and co-acting with the support provided by the flexible prong members of the carrier that secures each of the containers in vertical position, aligned so by the rigid support given by the part 6, thereby providing means for the top and bottom ends of the retained group of the containers to be in flat coplanar level position. These co-acting efiects in supporting the containers takes considerable strain off of the spring tempered members 16 and 22 of the carrier. Hence, it is not necessary to rely upon these members by themselves to keep each container in positive vertical position in the carrier. This also applies when manually lifting the loaded carrier by the handle means provided in the carrier whereby the weight of the packed containers vertically suspended therein is suitably balanced and distributed principally upon the rigid member 6 of the carrier which primarily keeps the containers in vertical position, this position being stabilized by the weight carrying top edges of the prong projecting members of the parts 16 and 22.
The loaded carriers may be efiiciently stacked together as illustrated in Fig. 13 showing the top and bottom ends of the containers engaged flatly upon each other without any interference of any part of the carrier. The handle bar 35 in retracted position co-ordinates the alignment of containers stacked and prevents any side-wise sliding of each stacked carrier unit as shown in Fig. 13. If desired, the parts 22 of the carrier 4 may be embodied with the rim section 32 shown in Figs. 4a and 5a that is intended to arrest longitudinal movement of the stacked carriers. This feature is useful for handling them in retail stores, warehouses and trucks where loaded carriers may be stacked high to conserve floor space. Stacked loaded carriers if desired may be strapped together in any suitable manner for transportation purposes from packers to the retail stores and thereby afford economy by eliminating the use of shipping case cartons. The retractable handle of the carrier may be utilized to clamp printed circular trade information upon the top of the carrier for commercial purposes pertaining to the product contained in the carrier.
The containers in the portable carrier are substantially fully exposed to advertise itself without resorting to printed brand identifying cartons for enclosing them as conventionally practiced. The use of the carrier can save large tonnage of paper-board used annually to make cartons for packing cans of beer, the cartons being discarded as waste material after its one time use. In contrast, the carrier of this invention may be utilized for the same useful purpose many times. When the carriers are made of aluminum and finally can not serve further useful purpose the aluminum material will yield a substantial price for scrap to melt in furnaces to make new carriers thus conserving the natural resources of the basic material.
The construction of the carrier affords a novel feature to make it easy to remove the containers from the carrier by making use of the leverage that is afforded by the container rim portion that is hooked over the sharp corner edges 9 of the rigid walls 8 of the carrier. For example, by pulling on a lower part of a supported container outwardly and upwardly in line with the prongs the container will fulcrum upon the corner edge 9 of the rigid walls 7 and 8 thereby being effective to easily release the container from the retaining pocket of prongs. The principle of the construction of the carrier is exceptionally flexible in its adaptability to provide group supporting means for four, six, eight, ten or twelve containers arranged in the manner shown in Fig. 1 by merely changing the length of the part 6 of the carrier and decrease or increase the number of the louvers thereof coincident with the simple duplication of the parts 16, the parts 22 remaining in the complement of one pair. The parts of the carrier may be modified in shape to accommodate the support of other types of like containers such as jars or bottles if desired.
While no substantial modification of the invention is illustrated or described, it should be understood by those skilled in the art that various changes may be made in the structure of the portable carrier without departing from the spirit of the invention. Reference will therefore be had to the appended claims for a definition of the limits of the invention.
