1. Field of the Invention
The present invention relates to shipping containers, in particular shipping containers that are fabricated at least in part from paper, paperboard and/or corrugated paperboard material. The present invention also relates to such containers that are convertible from a shipping configuration, to dispensing or display configurations.
2. The Prior Art
In stores which deal with dry goods that are sold in their own individual containers, such as grocery stores, a traditional method for placing the goods on display would be for store personnel to open the shipping containers in which the goods have been shipped from the supplier, and individually place each item on the shelf, and arrange them neatly for presentation. Typically, such containers were often structures dedicated solely to a shipping function, and when opened, were either destroyed, or resulted in an open-topped container not well suited for merchandising functions.
However, this process of individual removal of goods from a shipping container, and placement on shelves, is relatively costly to the store in terms of personnel effort, time, wages, etc. Therefore, it has become desirable to reduce costs in converting goods packaged for shipping into a suitable format for display and shopping.
This has resulted in the development of a variety of containers which are configured to be convertible from a shipping configuration, to a display configuration, which permits the converted container to be placed directly upon a shelf, or floor display, without having to remove the individual product items from the container. Typically, this is accomplished by providing the container with removable portions of the container that create apertures through which customers may then help themselves to the products within the converted container.
Such convertible containers represent a challenge in that they must be readily convertible into a form presentable to customers, while at the same time maintaining certain shipping performance characteristics, suitable for the shipment of non-self-supporting or even fragile products. In order to reduce cost in opening and placement of the converted container, the container should be hand-convertible, without the use of a knife or other implement. At the same time, it is desirable to provide a converted display container that is relatively free of unsightly or inconvenient rough edges or debris.
However, such prior art convertible containers often are either lacking in the necessary shipping performance characteristics or, in order to provide such performance, even after conversion, have structural elements that remain in position and make access to the product less convenient than desired. Other container constructions may achieve one or both of the performance or convenience goals, but at the expense of an inefficient or simply excessive use of container material.
It is accordingly desirable to provide a shipping container that is convertible to a display configuration, that has improved shipping performance characteristics, together with enhanced ease of conversion, and improved “shopability” for the consumer.
These and other desirable characteristics of the present invention will become apparent in view of the present specification and drawings.
The present invention is directed to a shipping container convertible to a display container, having a top, a bottom, first and second sides and first and second ends. The shipping container comprises, in part, an outer cover member formed from a first blank, including a bottom panel for forming the bottom of the shipping container. First and second side panels emanate from first and second opposing sides of the bottom panel. First and second end panels emanate from first and second opposing ends of the bottom panel.
The first and second end panels further include a bottom portion and a top portion. At least one of the first and second end panels further includes a zone of weakness enabling separation of the bottom portion from the top portion of the at least one of the first and second end panels. At least one reinforcement panel emanates from a top edge region of at least one of the first and second end panels, and is disposed in juxtaposed overlying relation to an inside surface of said at least one of the first and second end panels, and is affixed to an upper portion thereof.
At least one minor flap emanates from a side edge of said at least one of the first and second end panels, the at least one minor flap including a bottom portion and a top portion and a zone of weakness enabling facilitated separation of the bottom portion from the top portion of the at least one minor flap. A top panel is affixed to a top portion of at least one of the first and second end panels.
In a preferred embodiment of the invention, both of the first and second end panels include a zone of weakness enabling separation of the bottom portion from the top portion of both of the first and second end panels.
In one embodiment of the invention, the top panel is fabricated from a second blank of material discrete and separate from the first blank. In an alternative embodiment of the invention, the top panel is monolithically formed with and emanates from one of the first and second end panels. In this alternative embodiment, the top panel is joined to said one of the first and second end panels along a line of weakness, which enables manual separation of the top panel from said one of the first and second end panels.
The shipping container further preferably comprises at least one minor flap emanating from a side edge of the at least one reinforcement panel, and disposed so as to be juxtaposed to and in overlying relation to an inside surface of the at least one minor flap emanating from a side edge of said at least one of the first and second end panels.
In an embodiment of the invention, both of the first and second end panels include a zone of weakness enabling separation of the top and bottom portions of both of the first and second end panels. In this embodiment of the invention, the shipping container further comprises two reinforcement panels, emanating from top edge regions of each of the first and second end panels, and disposed in juxtaposed overlying relation to inside surfaces of the respective first and second end panels and affixed to upper portions thereof.
In an embodiment of the invention, the shipping container further comprises an aperture disposed in said end panel, for facilitating removal of the top panel.
Preferably, the zone of weakness is at least one of the following: a score line; a pull strip; at least one transverse line of perforations.
In an embodiment of the invention, the top panel further comprises at least one side flap, releasably adhered to a top portion of said at least one minor flap emanating from a side edge of said at least one of the first and second end panels, for enabling separation of the at least one side flap from the at least one minor flap, for further enabling separation of the top portion of said at least one minor flap from the bottom portion of the at least one minor flap.

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will be described in detail, several specific embodiments, with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.
In accordance with the usual conventions regarding the illustration of blanks for paperboard or corrugated paperboard articles, and unless otherwise specified, broken or interrupted lines within the boundaries of a blank represent scores, perforations or other lines of weakness, and extended solid lines, on the interior of a blank represent cuts.
Container 100 is formed in the following manner: in one preferred method, one blank 10 is drawn from a stack of blanks. The inner end panels 30, 36 are folded, about double fold lines 63, 36, until they overlie and are juxtaposed against the inside surfaces of end panels 18, 20, respectively. Prior to this step, adhesive is applied to either inner end panels 30, 36, or to upper end panels 18a, 20a, so that when folded over, lower end panels 18b, 20b are not affixed to adjacent portions of panels 30, 36. Inner end panel side flaps 32, 34, 38 and 40 may be adhesively affixed to end panel upper side flaps 22a, 24a, 26a and 28a, but not to end panel lower side flaps 22b, 24b, 26b and 28b. Alternatively, inner end flaps 32, 34, 38, 40 can also be folded at an angle (e.g., panel 32 including a sub-panel 32a, as shown in
At this point in the process (if not performed earlier), the goods to be contained are positioned on blank 10, centered over bottom panel 12. End panels 18 and 20 (together with respective inner panels 30, 36) are folded up perpendicular to bottom panel 12, while end panel side flaps 22, 32; 26, 34; 24, 38; and 28, 40, are folded perpendicular to end panels 18, 30; 20, 26. Side panels 14, 16 are folded up perpendicular to bottom panel 12, and adhesively adhered to end panel lower side flaps 22b, 24b, 26b and 28b. Cap blank 70 is then positioned over the articulated and glued wrapper (with goods inside). End flaps 78, 80 are folded down and adhesively affixed to upper end panels 18a, 20a. Side flaps 74, 76 are preferably folded down and only spot adhered to end panel upper side flaps 22a, 24a, 26a, 28a, so that with a relatively minimal amount of effort, side flaps 74, 76 can be pulled up away from end panel upper side flaps 22a, 24a, 26a, 28a, with relatively little damage thereto.
Once the folding and gluing process has been completed, the result is a container 100, as shown in a perspective view in
Formation of container 201 is accomplished by withdrawing a blank 200 from a stack of blanks. The goods to be packaged may be, at this point, positioned over bottom panel 202, or shortly thereafter. Inner front panel 220 is folded over to the inside of front panel 208. Inner front panel 220 is adhered to upper front panel 208a, while inner front panel side flaps 222, 224 are not adhered to front side upper panels 210a and 212a. Front panels 208 and 220 are folded up perpendicular to bottom panel 202, and rear panel 214 is likewise folded up perpendicular to bottom panel 202. Panels 210, 222; 212, 224 are folded perpendicular to front panels 208, 220, while rear side panels 216, 218 are folded perpendicular to rear panel 214. Side panels 204, 206 are then folded up perpendicular to bottom panel 202, and adhered to front side lower panels 210b, 212b, and rear side panels 216, 218. Alternatively, as shown in
While the goods to be packaged preferably have been positioned on blank 200 long before this stage in the articulation process, at this point container 201 comprises an open-topped container, into which the goods may be lowered. Thereafter, the container is closed by folding top panel 226 over the upper opening, folding down top panel side flaps 228, 230 and lightly (“spot”) adhering then to front side upper panels 210a and 212a, and to rear side panels 216, 218. Glue flap 282 is folded down over upper front panel 208a and adhered thereto, resulting in container 201, as shown in
The process of opening container 201 begins, as shown in
The die cut wrapper blanks 300 are stacked in a hopper (step I) Individual blanks 300 are drawn from the stack (step II). One blank 300 is drawn from the hopper and formed into a U-shape (step III). As the formed blank 300 is advanced along the formation path, adhesive is applied to inner panels 330, 336 (step IV). The U-shaped blank 300 is further folded until the inner panels 330, 336 are adhered to the exterior panels, specifically panels 318a, 320a (step V). lower end panels 318b, 320b are not affixed to adjacent portions of panels 330, 336. Inner end panel side flaps 332, 334, 338 and 340 may be adhesively affixed to end panel upper side flaps 322a, 324a, 326a and 328a, but not to end panel lower side flaps 322b, 324b, 326b and 328b. The folded blank, now having double-thickness side panels, is (preferably) compressed, and moved into a tray-forming section of the formation machinery (step VI).
The blank 300 is now formed into a tray (step VII). During these steps in the process (if not performed earlier), the goods to be contained may positioned on blank 300, centered over bottom panel 312. End panels 318 and 320 (together with respective inner panels 330, 336) are folded up perpendicular to bottom panel 312, while end panel side flaps 322, 332; 326, 334; 324, 338; and 328, 340, are folded perpendicular to end panels 318, 330; 320, 326. Side panels 314, 316 are folded up perpendicular to bottom panel 312, and adhesively adhered to end panel lower side flaps 322b, 324b, 326b and 328b. Alternatively, once the tray has been fully formed, the goods may be inserted into the formed tray by a drop packing section, such as are known in the art (step VIII).
The tray base formed from blank 300, with product inside, is then advanced to a lidder section (step IX). A plurality of cap blanks 302 are stacked in a hopper (step X). Successive cap blanks 302 are positioned over the articulated and glued wrappers (step XI). As a tray portion (articulated blank 300 plus product) is raised, flaps 374, 376, 378 and 380 are folded down and adhesively affixed to panels 318a, 320a and panels 322a, 324a, 326a and 328a (step XII). The sealed containers are then conveyed to another location for placement on pallets for shipment (step XIII).
Once the folding and gluing process has been completed, the result is a container 301, as shown in a perspective view in
Container 401 may also include, if desired, an internal divider (shown in
The die cut wrapper blanks 400 are stacked in a hopper (step I). Individual blanks 400 are drawn successively from the stack (step II). One blank 400 is drawn from the hopper and formed into a V-shape (step III). As the formed blank 400 is advanced along the formation path, adhesive is applied to inner panel 430 (step IV). Blank 400 is further folded until the inner panel 430 is adhered to the exterior panel 418, specifically panel 418a (step V). Lower end panel 418b is not affixed to adjacent portions of panel 430. Inner end panel side flaps 432, 434 may be adhesively affixed to end panel upper side flaps 422a, 426a but not to end panel lower side flaps 422b, 426b. At this point in the process, the wrapper blank is formed into a square “U”-shape.
Preferably, the folded blank 400 is now loaded with product, e.g., bottles, by pushing the product onto and over bottom panel 412 (step VI). After insertion of the product (e.g., bottles), one of panels 482, 483 is folded perpendicular to center panel 480 so that divider 402 forms an “L”-shape (step VII), and divider 402 is then dropped down among the array of product (step VIII). The remaining one of panels 482, 483 is then folded perpendicular to center panel 480, so that divider 402 assumes a “C”-shape, and flaps 422, 426, 424, 428 are folded 90° inwardly (step IX). Top panel 436 is folded downwardly parallel to bottom panel 412 (step X). Adhesive is then applied to panels 414, 416 (or to the corresponding surfaces of panels 422, 424, 426, 428), which are then are folded up and adhered in place, and adhesive is then applied to panels 438, 440, (or to the corresponding surfaces of panels 422, 426, but not panels 424, 428), which are then are folded down and adhered in place (step XI). Glue flap 470 is then folded down and adhesively affixed to panel 418a (step XII).
Once the folding and gluing process has been completed, the result is a container 401, as shown in a perspective view in
