CLIFFORD H. KEITH GLEIM 8 CANDOR m V. ATTORNEYS United States Patent Ofiice Ohio Filed Sept. 30, 1959, Ser. No. 843,498 10 Claims. (Cl. 229-37) This invention relates to improved containers and to improved blanks for making such containers. More specifically, this invention relates to heavy-duty containers being formed from paperboard or the like having reinforced bottoms, tops, and/or side walls thereof. This invention also relates specifically to improved blanks for forming such heavy-duty containers and the like.

This application is a continuation-in-part of my copending application entitled Container Structure for Packaging Nails, Serial No. 768,691, filed October 21, 1958, now abandoned.

It is well known in the container art that ordinary paperboard containers can not be readily utilized for heavy-duty purposes as the conventional structures lack sufficient strength and reinforcement means to support the relatively heavy loads of high density goods, nonrigid goods, and the like. Accordingly, when conventional paperboard containers are utilized for shipping and/ or storing high density goods and the like, the heavy loads of the goods that are imposed against the various Walls of'the'containers tend to rupture the same thereby resulting in subsequent loss and/or damage to the goods. Many unsuccessful attempts have been made by various manufacturers in the past to provide a heavy-duty "container that is relatively inexpensive to manufacture, relatively easy to assemble, and which is provided with suflicient reinforcing means to support the relatively heavy loads of high density goods and the like.

Accordingly, it is an object of the present invention to provide an improved heavy-duty container.

it .It is another object of the present invention to provide an improved container blank for forming such a container. Another object of the present invention is to provide an improved closure means for containers and the like. "Other objects, uses and advantages of the present invention will become apparent from a reading of the following specification taken in conjunction with the accompanying drawings forming a part hereof and wherein:

While various container structures of this invention are hereinafter described as being particularly adapted for packaging nails, it is to be understood that these container structures are also readily applicable for packaging other types of high density goods, non-rigid goods, and the like and may also be utilized for any other desired purpose. Further, because of the double side walls of these containers, the same have increased up and down strength and, therefore, these containers can be stacked with greater security and alignment. In particular, these containers are readily adaptable for palletizing and unitizing.

Reference is now made to the accompanying drawings wherein like reference numerals are utilized throughout the various figures thereof to designate like parts where appropriate, and particular reference is made to FIG- URES l-ll illustrating one embodiment of this invention.

A container structure of this invention is shown in collapsed form in FIGURE 1 and in erect form in FIG- URE 4, the container structure being indicated generally by the reference numeral 10. An improved blank of this invention is illustrated in FIGURE 7 and may be utilized for forming the container structure 10 in a manner hereinafter described.

As shown in FIGURE 7, the illustrated container structure It) of the present invention is formed from a substantially rectangular blank that is cut and scored to define a first series of four foldably connected side wall means or panels 12, 14, 16 and 13, and a corresponding second series of foldably connected and substantially coextensive liner panel means or liner panels 20, 22, 24 and 26, that are aligned in spaced relation with respect to the first panel series.

Between the respective adjacent edges of corresponding intermediate panels 16 and 24 and in each panel series, a connection panel 23 has opposed edges thereof foldably connected. This connecting panel 28 is foldably connected coextensively at the respective adjacent edges of the panels 16 and 24, and the extent of the connecting panel 28 between these foldably connected edges corresponds substantially to the Width of the respective panels 14 and 18, and 22 and 26, to each side of the panels at which it is foldably connected.

On each of the panels 2%, 22 and 26 of the second series, flap panels 30, 32 and 34 are foldably connected at the inner edges thereof, and these fiap panels 30, 32 and 34 are substantially coextensive in relation to the previously mentioned connecting panel 28. In addition, one terminal panel 2% of the second series has a side edge flap 36 foldably connected thereto. A similar side edge flap 38 is foldably connected to the terminal panel 12 of the first series, and the panels in this series have closure fi-aps 40, 42, 44 and 46 foldably connected at the outer edges thereof to complete the elements of the blank structure.

The collapsible nature of the container structure it of the present invention is provided for in the blank by medial scoring at 48 in the connecting panel 28 between the foldably connected edges thereof; and by further medial scoring at St}, 52, "54 and 56 in the respective first series panels 14 and 18, and second series panels 22 and 26, at each side of the panels to which the connecting panel 28 is foldably connected, as well as by aligned medial scoring at 58, 6Q, 62 and 64 in the respectively related closure flaps 42 and 46, and fiap panels 32 and 34.

In addition, the blank is further preferably formed with a tear tab 66 slit at the free edge of the side edge flap 38 on the terminal panel 1 2 of the first series in spaced relation from the outer edges of the panels of this first series, and in alignment with spaced scores 63 (see FIG- URES 1, 4 and 11) extending continuously across all of the first series panels 12, 14, 16 and 18 at the faces thereof opposite those shown in FIGURE 7, While a high strength reinforcing tape 70, such as a fiber glass tape, is applied across the inner faces of these panels in alignment with the tear tab 66 and tear strip 63, so as to provide for convenient opening of the container structure 10 to obtain access readily to a package load secured therein.

In forming the container structure 10 according to the present invention from the blank shown in FIGURE 7, the first step consists in folding flap panels 30, 32 and 34 downwardly in doubled relation with respect to the panels 2t), 22 and 26 of the second series on which they are foldably connected so as to arrange the blank elements in the form illustrated in FIGURE 8.

Nent the second series panels 20, 22, 24 and 26 are folded to the assembled relation shown in FIGURE 9 by doubling the panels 22 and 26 of this series at the medial scores 54 and 56, therein, the aligned medial scores 62 and 64 providing at the same time for similar doubling of the flap panels 32 and 34 inwardly thereof.

The thus assembled second series panels 20, 22, 24 and 26 are then placed in adjacent relation with respect to the panels of the first series by folding upwardly about the medial score 43 in the connecting panel 28, as illustrated in FIGURE 10-, so that the panel 20 of the second series is disposed in face-to-face relation with respect to panel 16 of the first series, and so that panels 14 and 18 of the first series may be doubled about the medial scores 50 and 52 therein to complete the folding of the blank elements, in the form shown in FIGURE 11, for securing at the side edge fiap 38, as by stapling at 72, to provide the container structure 19 of the present invention in collapsed form as seen in FIGURE 1.

To set up this collapsed carton structure 10 to the erect form shown in FIGURE 4, it is only necessary to push inwardly on the medially scored panels '14 and 18 of the first series so as to square up the container structure 10, and then told downwardly the flap panel 30 to a position overlying the connecting panel 28 in order to hold the container structure 10 in this squared position, whereupon the other medially scored flap panels 32 and 34 may be additionally folded downwardly to overlie the connecting panel 28 as well.

In this erect form, the panels 12, 14, 16 and 18 of the first series form the outer side walls of the container structure 10, with the closure flaps 40, 42, 44 and 46 thereon extending upwardly to form an open top for filling that may subsequently be closed in the usual manner. The outer bottom wall of the container structure 10 is formed by the connecting panel 28, with the additional flap members 30, 32 and 34 serving to complete a bottom in the container structure of four thicknesses. The remaining panels 20, 22, 24 and 26 of the second series form liner elements within the container structure 10 so that a double thickness of paperboard is provided at all of the side walls.

Upon filling of the container structure 10, a top pad may be placed therein, if desired, and the closing of the top end completed by simply folding and securing the top closure flaps 40, 42, 44 and 46 in the usual overlapping relation. The flap member 30 is provided on the liner panel 20 of the second series and may alternatively be separated and used as a top pad in the container structure 10, while still leaving a bottom of three thicknesses therein. Also, the medial scoring of the liner element panel 26 and the flap panel 34 thereon may be eliminated to increase the bracing action of these elements when the container structure 10 is erected. Either of these changes may be made in the container structure 10 without otherwise substantially changing the manner in which it is folded from the initial blank form to assembled collapsed form, or the manner in which it is set up to erect form.

The container structure 10 while being adapted for many uses, is particularly adapted for packaging nails as prior known paperboard nail container structures require tedious and time-consuming set-up operations in assembling the container structures from blanks as Well as involving a considerable packaging material inventory and a substantial allotment of space for the container assembly operations. The strength requirements for packaging nails also make it necessary to provide reinforcing liner elements in the container structure, and it has been found in the past particularly difficult to hold these liner elements properly in place during nail packaging operations
