Beart, Michael Kovac, Barry L. Clark and Jack R. Halvorsen ABSTRACT: This invention relates generally to a multipackaging device or carrier for containers and more particularly to devices for accommodating containers having a circumferential bead adjacent one extremity thereof, as for example the conventional bead on a can. The embodiment of the invention disclosed herein includes a paperboard sheet which is apertured to provide a plurality of pockets for receiving the extremity of beaded containers. The circumferential marginal area adjacent each aperture is adapted to be deflected out of the plane of the paperboard sheet upon telescopic association of a beaded container therewith so as to position the edge of said marginal area for engagement with the underside of the container bead. A flexible plastic film is adhered to the upper side of the paperboard sheet in superimposed relation with respect to the circumferential marginal areas. The portion of the film which superimposes the marginal areas serves to maintain the edge of the deflected margin in underlying relation with respect to the bead of a telescopically associated container.
CONTAINER-PACKAGING DEVICE A sheet of yieldable, resilient, and elastic material has heretofore been employed to accommodate a plurality of containers. Such devices are shown in applicants earlier US. Pat. No. 2,874,835 which issued on Feb. 24, 1959. It is an object of the present invention to provide an improved, multipackaging device for beaded containers having functional characteristics somewhat similar to the container carrier and package disclosed in the above-mentioned patent;
It is a further object of the present invention to provide a multipackaging or container carrier of the type referred to above which is readily disposable, and to this end it is proposed to produce a device which is readily combustible.
The present invention also contemplates a multipackaging device of the type referred to above which is very economical to produce and to this end it is contemplated to fabricate the device with a sheet of readily disposable paperboard and a v relatively thin disposable plastic film.
It is also an object of the present invention'to provide a combined paperboard and plastic film device which will not only grip the underside of the bead of a container but will also provide a protective coating for the entire upper surface of a plurality of containers.
The foregoing and other objects and advantages will be more apparent from the accompanying drawing wherein:
FIG. 1 is a perspective view of a multipackaging device of the type contemplated by the present invention disclosed in operative association with the upper extremities of a plurality of beaded containers or cans;
FIG. 2 is an end elevational view as seen from the left of FIG. 1; a FIG. 3 is a fragmentary plan view of one extremity of the assembly shown in FIG. 1, a portion of the film being broken away to illustrate the slits in the marginal area of the paperboard sheet;
FIG. 4 is a perspective view showing the paperboard sheet and thin film in vertically spaced or separated relation;
FIG. 5 is a fragmentary vertical sectional view taken substantially along the line 5-5 of FIG. 3, just prior to the telescopic association of the container with the combined paperboard and plastic film;
FIG. 6 discloses the position of the combined paperboard and film after the telescopic association of the container therewith has been completed; 7
FIG. 7 is an enlarged fragmentary view of the left-hand portion of the device as shown in FIG. 6; and
FIG. 8 is a fragmentary perspective view disclosing a modified undulated circumferential margin which may be axi- I ally deflected upon telescopic assembly therewith of a beaded container.
Referring now to the drawing more in detail wherein like numerals disclose similar parts throughout the various figures, it will be seen that one embodiment of a multipackaging device contemplated by the present invention is in the form of a can carrier designated generally by the numeral 10. This carrier device 10 consists of a pasteboard sheet or section 12 and a companion, relatively thin plastic film 14 adhered to the upper surface of the sheet 12. The paperboard sheet 12 is provided with a plurality of apertures 16, each aperture being defined by a circumferential marginal area comprising a plurality of radially disposed, axially deflectable fingers l8, separated by slits formed in the paperboard stock.
After the apertures 16' and the fingers 18 have been formed in the paperboard sheet 12, the relatively thin, flexible plastic film 14 is applied to the upper surface of the sheet 12 as by a suitable adhesive 20 indicated in FIGS. 4 and 7. These combined sheets 12 and 14 comprise the multipackaging or container device indicated generally by the numeral 10.
The internal diameter defined by the free extremities or edges of the fingers 18 must be less than the external diameter of the beaded portion of the container to be accommodated by each of the apertures 16. The containers disclosed in the drawing consist of cans 22 provided with conventional, circumferential beads 24 at each extremity thereof. As each container or can 22 is telescopically associated with its respective aperture 16, the fingers 18 are deflected axially as shown in FIGS. 6 and 7. In this deflected position, the free extremities or edges of the fingers l8 engage the underside of the bead 24, The film 14 is sufficiently flexible and elastic so that it may be shifted from the flat position shown in FIG. 5 to the stretched position shown in FIG. 7. In this position the film 14 serves to prevent radially outward deflection of the fingers from the position shown in FIGS. 6 and 7, thereby providing flexible container-engaging band while also maintaining the interlocked relationship of the free edges of the fingers with the underside of the head 24. It will also be noted that the upper surface of the can 22 is completely covered by the film 14. Thus in addition to maintaining the proper abutting relation of the free edges of the fingers 18 with the underside of the bead 24, the film 14 also provides a protective covering for the entire upper surface of the container or can 22.
In FIG. 8 the circumferential margin which defines the container-accommodating aperture is undulated as distinguished from the use of the fingers 18 previously described. By thus undulating the margin, sufiicient flexibility is imparted to the paperboard to assure proper upward flexing thereof when a container or can is telescopically associated therewith. In FIG. 8 this undulated margin is indicated by the numeral 18a.
From the foregoing, it will be apparent that the novel arrangement of the flexible, elastic plastic film in association with the upper surface of the paperboard presents distinct advantages over container-packaging or carrier devices heretofore available. The paperboard and thin plastic film are readily combustible and hence may be readily disposed of after the containers have been removed therefrom. The portion of the film immediately superimposing the fingers 18 or the undulated marginal area 18a serves to maintain the locking engagement of the marginal edge with the underside of the container bead. It should also be understood that the present invention contemplates a packaging device or carrier in which the film as well as the paperboard stock is apertured. In such instances, the film will not serve as a protective coating for the end surface of the container but will function to maintain the locking effectiveness of the marginal edge. In some instances, it may only be necessary to apply the film to a limited circumferential area in the vicinity of the prongs 18 or the undulated area 18a. Also, the invention contemplates adhering the film to the paperboard by means other than adhesives, as for example by stapling. The packaging device or carrier of the present invention may be produced very economically. By providing a pair of finger-accommodating apertures 26, the ease withwhich the device may be manually transported is greatly facilitated.
The term paperboard as set forth in the specification and claims is employed generically to define any type of cardboard, fiberboard and the like. The term bead is employed generically to define any circumferential shoulder means in the vicinity of the upper extremity of a container to be accommodated by the pockets.
The invention is claimed as follows:
, l. A multipackaging device for accommodating beaded containers, as for example cans having beaded extremities, including a paperboard sheet having pockets for receiving one extremity of a beaded container, each of said pockets comprising an aperture defined by the edge of the paperboard sheet and having a diameter which is less than the diameter of the beaded portion of the container to be accommodated, the circumferential marginal area of the sheet adjacent said aperture adapted to be deflected out of the plane of the sheet upon telescopic association therewith of a beaded container so as to position said edge for engagement with the underside of the container bead, and a flexible plastic film adhered to the upper side of said paperboard sheet in superimposed relation with respect to said circumferential marginal area, said flexible plastic film when adhered to the circumferential marginal area of the paperboard sheet cooperating to provide a flexible container-engaging band enabling the edge of the deflected marginal area to resiliently grip and engage the container below the beaded portion thereof.
