Abstract
Abstract This invention relates generally to means and methods for packaging containers, and more particularly to means and methods for packaging a plurality of containers having a circumferential shoulder or bead at the upper end thereof, as for example capped jars and conventional beaded cans. The embodiments of the invention disclosed in the present application include paperboard sheet material having container-accommodating apertures, the upper surfaces of such sheet material being treated as by spraying to condition said surface for subsequent attachment thereof to a flexible, elastic, plastic film or membrane. By subjecting the adjacently positioned film and previously treated paperboard to heat, these parts become firmly adhered to each other. The marginal edges defining each of the apertures in the paperboard underlie the shoulder of a bead or jar cap of a complementary container. The elastic film encapsulates the upper extremity of the container and thus the film serves both as a protective coating for the end surface of the container as well as means for maintaining the marginal edge of the paperboard or fiberboard in underlying contact with respect to the shoulder of an associated container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A packaging device for containers having a circumferential shoulder in the vicinity of the upper extremity thereof including paperboard sheet means in the form of elongate strips having adjacent margins and having pairs of opposed apertures formed along said margins, which apertures, when the margins of the strips are brought into adjacent relationship provide a plurality of container accommodating apertures having a diameter less than the diameter of the outer diameter of the upper extremity of a container to be accommodated thereby, and a plastic sheet adjacently superimposing the top surface and sidewalls of the upper extremity of the container and adhered to the upper surface of the paperboard so as to maintain the circumferential marginal area of the paperboard which defines said apertures in underlying relation with respect to the circumferential shoulder of the container.
Claim 2
Dependent Claim
136 words
A packaging device for containers having a circumferential shoulder in the vicinity of the upper extremity thereof including paperboard sheet means in the form of elongate strips having adjacent margins and having pairs of opposed apertures formed along said margins, which apertures, when the margins of the strips are brought into adjacent relationship provide a plurality of container accommodating apertures having a diameter less than the diameter of the outer diameter of the upper extremity of a container to be accommodated thereby, and a plastic sheet adjacently superimposing the top surface and sidewalls of the upper extremity of the container and adhered to the upper surface of the paperboard so as to maintain the circumferential marginal area of the paperboard which defines said apertures in underlying relation with respect to the circumferential shoulder of the container.
Claim 3
Dependent Claim
46 words
A packaging device as set forth in claim 1 wherein the facing edges of the paperboard strips are adapted for abutment with each other when the circumferential marginal area defining the apertures are in underlying relation with respect to the circumferential shoulder of an associated container.
Claim 4
Dependent Claim
36 words
A packaging device as set forth in claim 1 wherein the facing portions of the strip are adapted to overlap when the circumferential marginal area of the paperboard underlies the circumferential shoulder of an associated container.
Claim 5
Dependent Claim
45 words
A packaging device as set forth in claim 1 wherein the facing margins of the paperboard strips are adapted to be secured together when the circumferential marginal areas defining the apertures are in underlying relation with respect to the circumferential shoulder of an associated container.
Claim 6
Dependent Claim
38 words
A packaging device for containers as set forth in claim 1 wherein means in the form of scored areas are provided between the container accommodating apertures to facilitate separation of one packaged container from an adjoining packaged container.
Claim 7
Dependent Claim
28 words
A packaging device for containers as set forth in claim 1 wherein the paperboard strips are provided with lateral flanges to lend lateral strength to the paperboard stock.
Claim 8
Dependent Claim
28 words
A packaging device for accommodating containers as set forth in claim 1 wherein the paperboard strips are provided with flanges extending downwardly with respect to an associated container.
Claim 9
Dependent Claim
26 words
A packaging device for containers as set forth in claim 1 wherein flanges extending upwardly from the paperboard strips are provided to lend lateral strength thereto.
Claim 10
Dependent Claim
52 words
A packaging device for containers as set forth in claim 1 wherein the film sheet extends beneath the paperboArd strips and the opposite margins thereof extend over the sidewalls and upper surface of the container, said opposite margins of the plastic film being sealed adjacent the upper surface of an associated container.
Claim 11
Dependent Claim
28 words
A packaging device for containers as set forth in claim 1 wherein the paperboard sheet includes sections for extending along the side and bottom of an associated container.
Claim 12
Dependent Claim
30 words
A packaging device for containers as set forth in claim 1 wherein the paperboard material includes side sections through which a portion of the periphery of associated containers may project.
