Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to packages for containing a large number of individual container units such as cans or bottles. Combination packages for holding large numbers of individual containers have been used in the past to confine and render transportable in a commercially satisfactory manner the individual containers. Prior package units have suffered from a number of commercial drawbacks. Many previously used container units have been extremely moisture sensitive when formed from paperboard material. Moisture sensitivity increases the likelihood of product identifying label detachment or in extreme cases disintegration of the package during use or transit. In either case, the package is substantially diminished in its commercial usability. Previously, arrays of metal cans, for example carbonated beverage cans or beer cans, have been transported in paperboard boxes which are not only subject to the above mentioned moisture consideration but also mechanically deformation problems. When a number of paperboard boxes containing filled cans are stacked one upon the other, as they are during shipping and store display, the uppermost peripheral rim of the cans on the bottom of the stack of paperboard boxes is forced into contact with the paperboard of the top and bottom panels of the box. After prolonged exposure to the sharp rimmed portions of the can, the paperboard, especially when moist, is subject to unacceptable groove formation which adversely affects the package. A number of approaches have been used previously to store and transport large numbers of individual articles.

2. Description of the Art

In the past, many approaches have been used for the storing and transportation of large numbers of individual articles. For example, U.S. Pat. No. 1,909,898 discloses an egg carrier adapted to have eggs arranged in the usual fillers, the carrier having handles on it by means of which the carrier together with the entire contents can be inserted in or moved from an egg crate in a single operation. The handles are so positioned as to protrude through openings formed in the crate and serve as a means to handle the crate and also as an aid in maintaining the crates in their proper stacked relationship during shipping and handling.

The package further includes means for securing the extension portion to the adjacent wall and including a pair of spaced parallel tear lines. The tear lines extend inwardly of the wall from opposed ends of the securing flap to permit a portion of the wall to be ripped open with a jerking motion. Accordingly, the package during use comprises a completely enclosed package with a tear away type handle.

U.S. Pat. No. 2,788,933 discloses a beverage case including a rectangular paperboard container having side walls, end walls and closure flaps at top and bottom portions thereof, which are folded down and secured into a closed position by an adhesive strip, staple or like means. Hand holes are located in the end walls at diagonally opposed corner portions of the beverage case with the hand holes being oblong in shape.

U.S. Pat. No. 2,848,154 discloses a conventional cardboard carton with an integral handle assembly wherein the handle assembly comprises a bifold cardboard structure with one end affixed to an edge portion of the carton and a second distal portion including an oblong handle grip.

U.S. Pat. No. 3,119,544 discloses a composite package for use with a bag-in-box resealable, flexible packaging structure including the inner flexible bag and an outer stiff cardboard package. The cardboard package includes a foldable portion which provides access to the enclosed flexible bag.

U.S. Pat. No. 3,164,316 discloses a carton of conventional, total enclosure rectangular shape including a tear away handle on one edge thereof for gripping the carton. Further included is a tear strip which is disposed about three minor sides of the carton which when engaged allows opening of the carton in a clam shell like fashion.

The carrying container includes side flaps which are to be locatable in an open position to facilitate refrigeration and visibility of the beverages contained therein. The side flaps are also movable to a lockable, closed position to maintain the beverage containers in a cold condition for a substantial period of time. A handle means is provided to facilitate carrying of the container. A latching means is further provided between the openable top of the carrying container and the bottom of the carrying container to maintain an enclosure of a carrying container when desired.

U.S. Pat. No. 4,318,474 discloses a carton for carrying filled cans and later empty cans including a top, bottom, two sides and two end panels. One of the end panels is comprised of a three-ply laminated hand hold portion with the hand hold portion being flanked by a pair of hand holes in the end wall. The carton top includes a pair of top wall portions overlapping adjacent the center of carton and formed into a two-ply handle for carrying the carton filled with empty cans. The handle includes a pair of tabs one at each side of the handle holdable thereunder, under stress, over a row of cans disposed thereof for holding the cans in friction engagement and against lateral displacement.

SUMMARY OF THE INVENTION

The present invention relates to a package for holding a plurality of individual containers, such as cans or bottles in regular geometric arrays in container assemblies. The package according to the present invention includes a rigid tray member having a generally flat center portion and an upstanding peripherally located rim portion which extends around the entire periphery of the center portion. A plurality of discrete container assemblies are fitted within the rigid tray. Each of the container assemblies includes a plurality of individual containers in a regular geometric array. The individual containers are interconnected by a unitary thermoplastic carrier means to restrain the individual containers in the regular geometric array, for example a six-pack. A unitary, single sheet cover shroud having a center portion and at least a pair of depending, opposed unitary, single sheet side portions is connected to the tray rim to overlay the discrete container assemblies. The cover panel is spaced apart from the generally flat center portion of the tray by a distance approximately equal to the highest dimension of the discrete container assembly, to provide a snug fit for the container assemblies within the tray and cover shroud assembly. The side portions of the cover panel are connected to the upstanding perimeter rim portion of the tray. Handling means is provided for gripping and carrying the package.

The package according to the present invention is particularly advantageous in that it substantially reduces problems due to using composite packages in high moisture areas, also, problems related to stacking of a large number of packages, one on top of the other, for shipping and storage. Further, due to the minimal number of parts and minimal forming operation steps, the package of the present invention is relatively inexpensive to produce. Additionally, the package of the present invention provides easy access means to the enclosed container assemblies by means of a severable tear-tab on the cover shroud. Also, after opening the package, a portion of the cover shroud acts as a empty container restraining means to render the package returnable where statutes provide for return of all soft drink and beer containers after use. Further, the present package does not rely on an interference fit type tuck in tab for structural integrity. Such tabs cause severe continuous operation problems in high speed packaging production lines.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Referring to the drawings illustrating the advantages of the present package, there is illustrated in the figures a package for holding a plurality of individual containers arranged in regular geometric arrays in discrete container assemblies. Referring specifically to FIGS. 1-4, there is illustrated a package 20 including a tray 22. The tray 22 contains and partially encases a plurality of cans 24. The cans 24 are grouped into discrete container assemblies which are held in the tray 22. The discrete container assemblies 30 and 32 include a plurality of cans 24 within each of the carrier means 26 and 28. The container assemblies 30 and 32 fit within the tray 22 and are held therein partially by an upstanding tray rim 33. A single sheet unitary cover shroud 34 overlies the container assemblies 30 and 32 and is secured to opposed edges of the tray rim 33. Typically a hot melt adhesive or metal staples are suitable to secure the cover shroud 34 to the tray rim 33. The single sheet cover shroud 34 includes a flap type handle portion 36 and a severable portion 38. The severable portion 38 provides for convenient access to the container assemblies 30 and 32 upon use of the package 20.

Referring specifically to FIG. 3, there is shown a top plan view of the single sheet cover shroud 34 of the present invention. The cover shroud 34 is typically fabricated from double strength, high wet strength, paperboard packaging material. The paperboard material is printed with product advertising information and subsequently overcoated for additional scuff and abrasion protection. Any suitable paperboard varnish coating is acceptable for use with the present invention. The material in the preferred embodiment is approximately twenty-six mil thick. Such a thickness provides acceptable strength and stiffness characteristics without unnecessary cost. However, any suitable material may be used for the cover shroud 34, for example, thin sheet polyolefin materials, such as, polyethylene or polypropylene plastic. The cover shroud 34 is usually fabricated with a single stamping die which cuts the cover shroud 34 from a continuous length of paperboard feed stock. The cover shroud 34 is generally rectangularly, as shown in the preferred embodiment illustrated in FIGS. 1-4. In the preferred embodiment of the invention the cans 24 are groups within each container assembly 30 and 32, into a pair of three can linear arrays as shown, to form a so-called six pack. Any alternative geometric array is suitable.

The cover shroud 34 illustrated in FIG. 3 includes the severable portion 38 discussed above which provides convenient access to the container assemblies 30 and 32. The severable portion 38 is integral with the cover shroud 34 and includes a center tear strip 40 bounded on each side by the perforated score lines 42 and 44. Immediately adjacent score line 42 is a primary flap portion 46. The primary flap portion 46 blends into a fold line 48. The fold line 48 is adjacent to a handle aperture portion 50. The handle aperture portion 50 merges with a fold line 52. Adjacent to fold line 52 is a first side portion 54 which includes a handle aperture portion 56. Adjacent the score line 42 is a secondary flap portion 58 which terminates at the fold line 60. The fold line 60 connects with a second side portion 62. The portions 50 and 56, when secured togther by suitable means, cooperate to form the outstanding flap which comprises the handle portion 36.

FIG. 4 illustrates a top plan view of one of the thermoplastic carrier means 26 illustrated in FIGS. 1 and 2. The carrier 26 is typically a unitary, die cut, thermoplastic material structure. The carrier 26 is typically fabricated from low density polyethylene plastic due to their low cost and high mechanical strength and excellent elastic recovery characteristics. The carrier 26 in the preferred embodiment includes a plurality of peripherally located can top restraining portions 64 and a centrally located hand grip portion 66. The carrier 26 is disposed above a plurality of cans 24 with a regular geometric array matching the geometric array of the can top retaining portion 64. Subsequently, the carrier 26, which is cold, is stretched open by mechanical fingers and is lowered onto the geometric array of cans 24. The fingers are retracted and by the elastic recovery of the material, a frictional engagement with the cans 24 is achieved to result in the container assembly 30.

One of the advantages provided by the present invention is the reduction of package degradation by substantial indentation into the package by the chimes or rims of the cans 24. The tray 22 in the preferred embodiment of the invention is made from a high strength corrugated paper product which can effectively absorb any indentations by the rims of the cans 24 during shipping and storage. Accordingly, when packages 20 are stacked one on top the other for shipping and storage, the lower rims of the cans 24 are forced into the corrugated matrix on the inside of the tray 22 such that the tray absorbs the circular indentation formed by the rims. In the case of an immediate subjacent package 20, the top surface of the cover shroud 34 is in contact with the upper rim of the cans 24. However, due to the rigidity of the corrugated tray material for the tray 22 immediately above and in contact with the top of the cover shroud 34 of the lower package 20, only minimal indentations by can rims are possible. Accordingly, the bottom of the package is protected from substantial indentations by can chimes by the use of the tray 22 of a thicker material, having more rigidity and indentation absorbing capabilities than the material used for the cover shroud. Such a fabrication expedient lowers the overall cost of the package substantially without reducing the structurally integrity or aesthetic character of the package. The indentation created by the can rims on the corrugated tray are on the inside and thus invisible from the exterior of the package.

FIGS. 5a-c illustrate a schematic view of the use of the package 20 of the present invention. At FIG. 5a is illustrated the package 20 of the present invention showing the severable portion 38 being removed from the center of the cover shroud 34. After the severable portion 38 is removed and discarded, the package 20 is opened providing access to the container assemblies 30 and 32. The container assemblies 30 and 32 can be removed individually for refrigeration and use. The primary flap portion 46 and secondary flap portion 58 are folded inwardly of the tray 22 and placed adjacent to the first side portion 54 and second side portion 62, respectively. The inward folding of the primary flap portion of 46 and secondary flap portion 58 provides a spring biasing effect so that the cans 24, when emptied of contents, may be returned to the tray 22 for storage and subsequent return to the place of purchase. This is particularly advantageous in areas where it is legally required to sell only returnable containers for environmental reasons. The spring biasing of the primary and secondary flap portions 46 and 58, respectively, provides a mechanism of holding the empty cans 24 in the tray 22, with the assistance of the first and second side portions, 54 and 62 respectively, for ease of return of the empty cans 24.

FIG. 6 illustrates a perspective view of an embodiment of the invention illustrated in FIGS. 1-5 wherein a promotional advertising card 68 is affixed to the internal surface of the upstanding rim portion 33 of the tray 22. The card is inserted between the innerwall of the upstanding tray rim 33 and the cans 24 and either held by friction, an adhesive or metal staples. FIG. 6 illustrates the handle portion 36 in the folded down position to avoid obstruction on the conveyor line during assembly of the package. An adhesive can be used to hold the handle portion 36 down until consumer use is required.

An alternative embodiment of the invention of FIGS. 1-5 is illustrated in the perspective view at FIG. 7. A product identifying label 70 is disposed on one major surface of the flap type handle portion 36. In the embodiment of the invention shown in FIG. 7, the product label is a unit product code, computer scannable product identifying label. Such unit product code labels are read by computer scanning devices to militate against the individual price stamping of each article of commerce. Such unit product code can be directly printed on the handle portion 36 or separately prepared and affixed to the handle portion 36 with suitable adhesive.

FIG. 8 is a perspective view of an alternative embodiment of the package according to the present invention wherein a pair of packages 20 are secured together by a primary closure means 72 having disposed thereupon a product identifying label 74, and a secondary closure means 76 bearing a secondary product identifying label 78. Only one product identifying label, either label 74 or 78 need be used. However, both may be used if desired. The primary closure means 72 is typically a unitary die cut paper portion which is looped through the adjacent handle portions 36 and secured together at its end to form a unitary primary closure means 72. Thereafter, the product identifying label 74, typically a unit price code identifying label, is affixed to the primary closure means 72. Similarly, the second closure means 76 is a unitary die cut paper portion with a product identifying label 78 affixed thereto. The closure means 76 is adhesed or stapled to the abutting end portion of the packages 20.
