Abstract
Abstract A composite package having three separably connected containers. The containers are initially formed integrally as receptacles in a base sheet of a self-supporting plastic material, each receptacle being open at its upper end and closed at the bottom. A cover sheet is bonded to the upper face of the base sheet to overlie the open ends of the receptacles. The cover sheet is formed with small product dispensing apertures which register with the open ends of the receptacles. A peelable top sheet is applied over the cover sheet to cover the dispensing openings. The three sheets are severed in a predetermined manner and along predetermined lines between the receptacles to facilitate separation of the containers from one another and to provide lift tabs facilitating peeling of the top sheet from the cover sheet when it is desired to dispense the product. The receptacles are filled with product through the open upper ends thereof before the cover sheet is applied thereto.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
206 words
A composite package having a plurality of separably connected containers comprising a self-supporting base sheet having a pair of spaced apart receptacles therein which are closed at the bottom and open at the top, each receptacle having a generally flat peripheral lip portion extending around its upper end, a cover sheet overlying said base sheet and bonded to said lip portions around the periphery of each receptacle, said cover sheet having a dispensing opening therein overlying the open upper end of one of said receptacles, said dispensing opening being substantially smaller in size than the open end of the receptacle which it overlies to permit controlled discharge of the contents of said one receptacle when the latter is inverted, a top sheet overlying that portion of the cover sheet which contains said discharge opening and also overlying the portion of the cover sheet extending between the two receptacles, said top sheet being bonded to the cover sheet so as to be readily peelable therefrom, said base, cover and top sheets being severed along registering lines extending between said receptacles, said registering lines terminating at opposite ends thereof slightly inwardly of edge portions of the package so as to retain the containers in a separably connected condition.
Claim 2
Dependent Claim
206 words
A composite package having a plurality of separably connected containers comprising a self-supporting base sheet having a pair of spaced apart receptacles therein which are closed at the bottom and open at the top, each receptacle having a generally flat peripheral lip portion extending around its upper end, a cover sheet overlying said base sheet and bonded to said lip portions around the periphery of each receptacle, said cover sheet having a dispensing opening therein overlying the open upper end of one of said receptacles, said dispensing opening being substantially smaller in size than the open end of the receptacle which it overlies to permit controlled discharge of the contents of said one receptacle when the latter is inverted, a top sheet overlying that portion of the cover sheet which contains said discharge opening and also overlying the portion of the cover sheet extending between the two receptacles, said top sheet being bonded to the cover sheet so as to be readily peelable therefrom, said base, cover and top sheets being severed along registering lines extending between said receptacles, said registering lines terminating at opposite ends thereof slightly inwardly of edge portions of the package so as to retain the containers in a separably connected condition.
Claim 3
Dependent Claim
84 words
A composite package as called for in claim 1 wherein one of said edge portions of the package is defined by a laterally inwardly extending recess in the free edge of the base sheet and cover sheet, said top sheet overlying said recess, said registering lines extending into said recess at one end whereby when the receptacles are separated the portions of the top sheet overlying the recess provide pull tabs for facilitating peeling the top sheet from the cover sheet on each receptacle.
Claim 4
Dependent Claim
62 words
A composite package as called for in claim 1 wherein said cover and base sheets are severed along registering lines which extend from a point adjacent but spaced from one end of the first-mentioned registering lines of severing to at least closely adjacent one of said edge portions, the portion of the top sheet overlying the second-mentioned lines of severing being imperforate.
Claim 5
Dependent Claim
26 words
A composite package as called for in claim 3 wherein the first-mentioned registering lines of severing are substantially longer than the second-mentioned registering lines of severing.
Claim 6
Dependent Claim
19 words
A composite package as called for in claim 1 wherein the top sheet overlies the cover sheet substantially completely.
Claim 7
Dependent Claim
39 words
A composite package as called for in claim 1 wherein the cover sheet has a dispensing opening therein which registers with the other receptacle and which is substantially smaller in size than the open end of said other receptacle.
Claim 8
Dependent Claim
44 words
A composite package as called for in claim 6 wherein the second-mentioned dispensing opening is located at a portion of said other receptacle which is adjacent said one receptacle, said top sheet overlying the second dispensing opening and only partially overlying said other receptacle.
