Further downward movement of panel row 37 (now defining a hexagon in plan view) causes the interleaving of the closure panels, as shown in FIGURE 12 to progress toward the closure panel arrangement of FIGURE 2, and further initiates the telescoping of outside carton portions 37 and 35 over the liner portion 27 to bring the parts of the carton first into the nearly closed condition of FIG- URE 3 and finally into the fully closed condition of FIG- URE 1.
- Blank 70 generally designates the die cut rectangular blank.

Divided and this application Oct. 9, 1963, Ser. No. 314,951 Claims. (Cl. 22941) This application is a division of application Serial No. 81,865, filed January 10, 1961, which now has issued as Patent No. 3,107,042 on October 15, 1963.
The present invention relates to a collapsible carton and more particularly to a collapsible carton formed from a single blank of corrugated cardboard or equivalent material die cut and creased to define five rows of horizontally aligned edge-joined panels, the middle set of which are joined at their free edges to define a circumferentially continuous carton liner, the upper and lower rows being folded to the outside and then likewise joined at their free edges to define continuous outer carton portions telescopically engageable over the top and bottom ends of the carton liner, and the intermediate rows being notched and creased so as to automatically interleave to form the top and bottom closures as the carton parts are telescoped together.
Specifically, there is provided a single die cut blank of corrugated cardboard or similar relatively stiff but bendable material. The blank has a central row of edge-joined panels, the free edges of the end panels of which are joined to each other as by the use of a strip of adhesive tape to define a circumferentially continuous carton inner wall or liner. The blank also has a top and bottom row of panels folded to the outer side of the carton and similarly joined at their free edges to define continuous bands telescopically slidable over the upper and lower ends of the liner portion. Between the said upper and central and again between the central and lower rows of panels, which define the double thickness walls of the carton, there is a row of closure forming panels each of which is centrally and horizontally creased so as to be foldable upon itself and is cut away along the edge of one or both halves thereof to define a notch into which the folded edge of an adjacent panel may extend as said closure forming panels fold inwardly and interleavingly to auto matically form multiply top and bottom closures of the carton as the wall portions thereof are telescoped together, or to open the same on a reverse movement of the parts.
It is accordingly an object of the invention to provide a single blank carton having telescopically mating inner and outer walls and top and bottom closures automatically closed or opened by the relative telescopic movements of the carton walls.
It is another object to provide a carton of this type which can be collapsed into a flat package for shipping or storage either before or after use as a carton.
It is another object to provide a device of the character described in which all of the blank material initially en compassed within its margins is utilized to provide multiple walls for the carton sides and closure.
It is a further object of the invention to provide a collapsible carton which is simple in construction, inexpensive to manufacture and yet effective and efiicient in use.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
FIGURE 1 is a side elevational view of a closed carton embodying the invention;
FIGURE 2 is a plan view of the carton of FIGURE 1;

FIGURE 15 is a fragmentary plan view of a blank for a modifiefid form of the carton;
FIGURE 16 is a plan view of the partially closed carton formed by the blank of FIGURE 15;
FIGURE 17 is a fragmentary elevational view of the showing of FIGURE 16, in section and taken on line 17-17 of FIGURE 16; and,
FIGURE 18 is a plan view similar to FIGURE 16 but showing the carton fully closed.
With reference now to FIGURES 1 through 14 of the drawings, numeral 20 generally designates the die cut rectangular blank. Blank 20 may be cut from any suit able sheet material such as corrugated cardboard. A central transverse extending row of rectangular panels 21 through 26 defines the inner or liner portion of the two ply carton, said liner being generally designated by numeral 27. The panels 21 through 26 are defined by the hinge score lines at 287 A second row of panels 29 through 34 is collectively designated by numeral 35. The panels of row 35 are similarly hingedly connected and defined by score lines 36. The row of panels 35 constitutes the lower portion of the telescopic outer members of the completed carton.
The upper portion of the outside carton walls is formed by a row 37 consisting of panels 38 through 43 similarly joined by score lines 44.
As best seen in FIGURE 7, each of the panels 21 through 26 is joined at its lower edge along fold lines 45 to the upper end of one of the identical panels 46 which form the bottom closure of the carton in a manner hereinafter fully described.
The panels 46 are likewise connected at their lower ends to the upper edges of panels 29 through 34 at scored hinge lines at 47.
Each panel 46 has impressed therein a double score line 48 horizontally and medially disposed in the right half of each panel 46. Each panel 46 is separated from adjacent panel 46 by a die cut slit 49. Each panel 46 is further provided with a slit 5G and with a pair of score lines 51, which together define flaps 52, the purpose of which will hereinafter be more fully described.
FIGURES 8 and 9 illustrate the next step of folding flaps 52 and 57 against the inside surfaces of folding closure panels 46 and 53, respectively, in which positions they are firmly retained by application of adhesive to the engaging surfaces thereof.
FIGURES 9 and 10 show the next step of folding the outside panel rows 37 and 35, respectively, down over the upper portion of panels 53 and upwardly over the bottom portion of closure panels 46.
The final assembly step is indicated in FIGURE 5 in which the free ends of rows 37, 27 and 35, respectively, are joined together by strips of adhesive tape 61, 62 and 63-. The strips of adhesive tape 61, 62 and 63 hingedly connect the adjacent edges of the panel rows aforesaid.
To erect the box, the same is positioned as shown in FIGURE 4, standing on the row of panels 35 as a base. Downward pressure on the upper edge of panel row 37 initiates the inward bowing of the rows of closure panels 53 and 46 as shown in FIGURES 3, 12, 13 and 14. Further downward movement of panel row 37 (now defining a hexagon in plan view) causes the interleaving of the closure panels, as shown in FIGURE 12 to progress toward the closure panel arrangement of FIGURE 2, and further initiates the telescoping of outside carton portions 37 and 35 over the liner portion 27 to bring the parts of the carton first into the nearly closed condition of FIG- URE 3 and finally into the fully closed condition of FIG- URE 1.
Because of the greater vertical dimension of panel row 35 as compared to panel row 37, the frictional inter-engagement between panel row 35 and liner 27 will be greater than between liner 27 and panel row 37. Thus, an upwardly exerted pull on portion 37 will tend to cause an opening of the upper closure formed by panels 53 before liner 27 will begin to slide from the lower outside carton portion 35. Only when it is desired to re-collapse the carton back to its condition of FIGURE 5 for storage, will liner 27 be withdrawn from the lower carton portion 35.
In the species of FIGURES 15 through 18, numeral 70 generally designates the die cut rectangular blank. Blank 70 has the same basic construction and arrangement of parts described in the species of FIGURES 1 through 14, and, therefore, only the portions thereof containing the structural differences have been illustrated in FIGURES 15 through 18.
The row of edge-joined panels 71-76 form the upper outer carton Wall portions and correspond to telescopic part 37 of the first-described species. The row of edgejoined panels 77-82 (corresponding to panels 21-26) constitute the inner wall or liner of this carton.
Blank 70 differs from blank 20 essentially in the configurations of closure forming panels 83-88, which interleave to form the upper closure. (The lower closure, not shown, is of similar construction.) However, panels 83- 88 are only laterally disconnected from their adjacent panels for half of their lengths by the cut out areas designated 89. These areas receive the edges of panels 83-88 when they fold about their scored midlines 90. The upper portions of the panels 83-88 are laterally joined by integral webs 91 and 92 defined by scored fold lines 93, 94 and 95, which render the webs sufiiciently flexible to insure proper interleaving of the closure forming panels 83- 88. Webs 91 and 92 perform the important function of providing a seal between the adjacent upper edges of closure panels 83-88 to prevent leakage into or from the carton between the overlapped panel portions. The free edges of panel rows 77-82 and 83-88 are joined (as by adhesive tape 96) to form circumferentially continuous paneled bands, as in the first-described species.
As panels 77-82 telescope down over panels 83-88 (FIGURE-S 16 and 17), webs 91 and 92 first fold toward each other about fold lines 94 to permit initiation of the interleaving of panels 83-88, and then as the process continues they unfold into their initial coplanar relationships (as shown in phantom in FIGURE 18).
While the foregoing presents preferred embodiments and methods of the present invention, it is obvious that other modifications and/ or equivalents may be employed without departing from the scope of the invention, which is defined in the appended claims.
What is claimed is:
1. A plurality of edge-joined panels defining a circumferentially continuous inner wall of a carton, a like number of edge-joined panels defining the lower portion of the outer wall of said carton, a mating set of edge-joined panels defining the upper portion of the outer wall of said carton, and sets of vertically elongated closure forming panels joining the top and bottom edges of said inner Wall panels respectively to the top and bottom edges of the panels defining the upper and the lower outer wall portions, each of said closure forming panels having a horizontal medial fold crease formed therein and being provided with at least one vertically elongated wedge-shaped cut-out area in and along one side thereof with the apex of said area lying at a corner of said panel and the base of said area being closely adjacent the medial fold crease, said closure forming panels having wedge-shaped creasedefined webs connecting lateral edges of adjacent panels beyond the base of said cut-out areas and having fold creases extending longitudinally and from the apices thereof to enhance the flexibility thereof, said webs sealing the margins of the fiat spaces between interleaved panels against leakage, whereby said latter panels will fold inwardly with each receiving the medially folded edge of an adjacent panel within the pocket defined by the base of said area to provide a sequential interleaving of said sets of closure forming panels to define top and bottom closures for said carton as said upper and lower outer wall portions are telescoped axially over the upper and lower ends of said carton inner Wall.
