Package construction

Claim 2

A package construction comprising a tray having coplanar top surface portions and a plurality of containers carried within said tray; each of said containers comprising a side wall, an annular flange extending outwardly from said side wall, and a closure sealed against said annular flange and having at least a portion thereof extending outwardly of said flange; said tray having at least one elongate open-top chamber defined by a bottom wall adjoined by an upwardly extending tubular wall, a set of flange supports adjoining said tubular wall and supporting said flanges and containers thereon, and a set of closure supports, adjoining associated ones of said flange supports, said closure supports being disposed beneath said coplanar top surface portions, said closure supports receiving said outwardly extending portions of said closures therewithin beneath said coplanar top surface portions.

Claim 3

A package construction as set forth in claim 1 in which said bottom wall has a generally oblong configuration defined by elongate opposed side edges and opposed curved end edges, said tubular wall is defined by opposed side walls each adjoining an associated elongate side edge and opposed curved end walls each adjoining an associated curved end edge and interconnecting associated ends of said opposed side walls, and each of said curved end walls has an associated container disposed therewithin.

Claim 4

A package construction as set forth in claim 2 in which said opposed side walls have cooperating pairs of inwardly concave side wall portions with each cooperating pair having an associated container disposed therewithin.

Claim 5

A package construction as set forth in claim 3 in which each of said curved end walls and inwardly concave side wall portion is spaced from an associated container to provide a protective gap therebetween yet is sufficiently close to restrain the bottom portion of the associated container.

Claim 6

A package construction as set forth in claim 3 in which the side wall of each of said containers is substantially frustoconical and each of said curved end walls is approximately semifrustoconical.

Claim 7

A package construction as set forth in claim 3 in which said annular flange of each of said containers has a substantially toroidal bead defining the outer end portion thereof, said bead supporting its container on an associated flange support.

Claim 8

A package construction as set forth in claim 6 in which, said closure of each of said containers is a substantially sheet-like closure said portion of said closure extending outwardly from said flange includes an annular portion extending radially outwardly of said toroidal bead and a substantially triangular portion extending outwardly of said annular portion, and each closure support of said set of closure supports includes a ledge portion supporting an associated annular portion and a ledge portion of substantially triangular area supporting an associated triangular portion of said closure.

Claim 9

A package construction as set forth in claim 3 in which said tray is a single-piece tray made of a synthetic plastic material and has a substantially uniform thickness throughout all of its component portions.

Claim 10

A package construction as set forth in claim 3 and further comprising means confining said containers within said tray beneath said coplanar top surface portions.

Claim 11

A package construction as set forth in claim 9 in which said confining means comprises a sheet of transparent plastic film.

Claim 12

A package construction as set forth in claim 3 in which each of said trays has a plurality of lugs extending from its corners which enable a plurality of empty trays to be stacked in nested relation in a nonwedging manner.

Claim 13

A package construction as set forth in claim 11 in which each tray has integral means in the form of a cup-like structure adjacent one end thereof which assures that said plurality of empty trays may be stacked with the same orientation.

Claim 14

A package construction comprising a single-piece tray and a plurality of containers carried within said tray; each of said containers comprising, a side wall having a top edge portion, an annular flange extending outwardly from said top edge portion and terminating in a peripheral toroidal bead, and a closure sealed against said bead and having at least a portion thereof extending outwardly of said flange; said tray having a top wall and a plurality of open top chambers disposed beneath said top wall and each of said chambers being defined by a bottom wall adjoined by an outwardly extending tubular wall, said top wall comprising, a set of flange supports adjoining an associated tubular wall and supporting said flanges of associated containers thereon, a set of closure supports adjoining associated ones of said flange supports, a plurality of coplanar top surface portions adjoining said closure supports, said closure supports receiving said outwardly extending portions of said closures therewithin beneath said coplanar top surface portions, and a plurality of roughly V-shaped structures each having opposed end edges which adjoin and coincide smoothly with the closely adjacent sides of adjacent tubular walls of adjacent open top chambers.

Claim 15

A package construction comprising a single-piece tray and a plurality of containers carried within said tray; each of said containers comprising, a side wall having a top edge portion, an annular flange extending outwardly from said top edge portion and terminating in a peripheral toroidal bead, and a closure sealed against said bead and having at least a portion thereof extending outwardly of said flange; said tray having a top wall and a plurality of open top chambers disposed beneath said top wall and each of said chambers being defined by a bottom wall adjoined by an outwardly extending tubular wall, said top wall comprising, a set of flange supports adjoining an associated tubular wall and supporting said flanges of associated containers thereon, a set of closure supports adjoining associated ones of said flange supports, a plurality of coplanar top surface portions adjoining said closure supports, said closure supports receiving said outwardly extending portions of said closures therewithin beneath said coplanar top surface portions, and a plurality of roughly V-shaped structures each having opposed end edges which adjoin and coincide smoothly with the closely adjacent sides of adjacent tubular walls of adjacent open top chambers.

Claim 16

A package construction as set forth in claim 13 in which said top wall has a depending skirt extending about its entire periphery, said depending skirt cooperating with said V-shaped structures to assure said tray maintains rigidity about a central longitudinal axis therethrough upon urging the bottom portions of the tubular walls toward each other.

Claim 17

A package construction as set forth in claim 14 in which each of said containers is supported by its annular flange so that a bottom surface thereof is disposed in spaced relation above the bottom wall of its compartment.

Claim 18

A package construction as set forth in claim 13 in which said top wall is comprised of a plurality of spaced top portions including corner portions, side portions, and central portions, one of said central portions being disposed closely adjacent one end of said tray and having a cup-shaped structure extending from its top surface which assures a plurality of empty trays may be stacked with the same orientation.
