Abstract
In the production of packages made of relatively rigid packaging material, e.g. cardboard, it is not possible to directly fold the blank around the pack contents, if the pack contents are composed of articles which may not be mechanically strained, as for example, soft packs. A folding sleeve (47) which can be moved together with the pack contents makes it possible to fold a cardboard blank (28) around the pack contents. The folding sleeve (47) surrounding the pack contents absorbs the mechanical strain occurring in the folding process. Before completing the package, the folding sleeve (47) is pulled out of the region of the pack contents.
Claims10
A package shipping and point of sale display system comprising:
- a plurality of rectilinear packages (11) of uniform size;
- and
- a self-supporting rectilinear packing carton formed from a single carton blank for securely containing during shipment and for display the plurality of rectilinear packages (11) arranged in transversely extending parallel files that abut along a vertical parting plane, said carton comprising:
- a bottom wall (14) and a pair of upright opposing side walls (15,16) joined to the bottom wall along transverse fold lines, which walls contact and support the plurality of rectilinear packages, the edges of said bottom and side walls defining a top opening and opposing end openings, each of the longitudinal edges of said bottom and side walls being joined along a fold line to a lateral strip (20, 21, 22) that projects into the end openings, said lateral and transverse strips enclosing a minor portion of the end and top openings, the lateral side wall strips being securely joined in overlapping relation to the adjacent lateral bottom wall strips, the transverse edge of the upper ends of each of the side walls being joined along a fold line to a transverse strip (23, 24) that projects into the top opening to contact the tops of the plurality of abutting packages, the ends of the transverse strips being joined along fold lines to corner tabs (26, 27), said corner tabs being securely joined in overlapping relation to the confronting ends of the adjacent lateral side strips (21, 22), to thereby form the self-supporting carton and secure the rectilinear packages in said carton, and
- a U-shaped paper cover (13) extending over the top and end openings and adhesively bonded to the outer surface of the lateral and transverse strips by spot gluing.
A method of forming a package shipping and point of sale display system that includes a self-supporting packing carton containing a plurality of rectilinear packages (11) arranged in two files that abut along a vertical parting plane, said method comprising the steps of:
- (a) providing a one-piece carton blank comprised of a longitudinal web of packaging material, said web being divided by transverse and longitudinal fold lines to define a central bottom wall panel (14) positioned between a pair of side wall panels (15, 16), the dimensions of the bottom panel (14) corresponding to those of the arranged packages and the height of the side wall panels corresponding to the height of the arranged packages, the opposing longitudinal edges of each of the bottom and side wall panels being joined to a lateral strip (20, 21, 22) along a fold line, the ends of the transverse strips being joined along fold lines to corner tabs (26, 27), where the width of the lateral bottom strip is substantially less than the height of the side wall panel, and the combined width of the transverse strips (23, 24) and the combined width of the side wall lateral strips (21, 22) is each substantially less than the distance between the side wall panels (15, 16);
- b) placing the plurality of rectilinear packages (11) arranged in two parallel transverse files on the bottom panel (14) of the carton blank (12);
- c) folding the side wall panels (15, 16) vertically to a position contacting the packages (11);
- d) folding the bottom and side wall lateral strips (20, 21, 22) and the transverse strips (23, 24) along said fold lines into overlapping contact with each other and with the packages;
- e) joining the respective ends of the side wall lateral strips (21, 22) to the ends of the adjacent bottom lateral strips (20) and joining the corner tabs (26, 27) of the transverse strips (23, 24) to the ends of the adjacent side wall lateral strips to thereby form the self-supporting carton and secure said plurality of packages in the carton,
- f) folding a paper cover (13) into a U-shaped configuration and securing the cover to the lateral and transverse strips by spot gluing with an adhesive to cover the area of the openings between the lateral and transverse strips of the formed packing carton.
