7 Claims.

This invention relates to containers and more particularly to a novel packing and shipping case` formed from paperboard or like material and particularly adapted for the handling and shipping of bottled goods or other commodity units and to a blank for forming such case.

In accordance with one illustrative embodiment of. the invention, the case or container is formed from one or more blanks of paperboard or other suitable material suitably formed and assembled. The container is constructed from a blank or blanks cut, scored and folded up to form a bottom wall, side walls, end Walls and cover members hinged to the top edges of the side Walls. Portions oi the cover members Jare folded over and secured to provide inherently rigid, upstanding anges extending along at least certain of the free edges of the cover members to assist in longitudinally reinforcing the container. The anges are adapted to engage with each other and/or with other portions of the container to retain the cover members in closed position. A suitable divider or partitioning means is provided for insertion within the container to define a plurality of cells and a portion or portions of the d1- vider extends substantially to the top of the container for interengagement of the ianges to the cover members to assist in securing them in closed position.

The invention provides a container which can be easily and economically formed from one or Vmore relatively simple blanks of paperboard or other sheet material, which can be readily and economically set up and assembled to form a container, which can be easily packed, and which provides a sturdy and convenient storing, handling and shipping case for bottles, bottled goods or other consumer units. l

In the following description and in the claims, 45 various details will be identiiied by specific names for convenience, but they are intended to be as generic in their application as the art will permit. Like reference characters denote like parts in .the several gures of the drawings.

In the drawings accompanying and forming part of this specification, certain specific' disclosure of the invention is made for purposes of explanation, but it will be understood that the details may be modied in various respects with- 55 out departure from the broad aspect of the in vention.

In accordance with the present invention, the

container may be constructed from paperboard, box board, corrugated board or other sheet material of sufficient rigidity to retain the shape of the container and to provide the necessary mechanical strength, and of sufficient flexibility to permit the required bending and folding. Where the container is to be used for certain goods or is otherwise subject to wetting, the material may be suitably coated or impregnated to render it moisture-proof, as will be understood by those skilled in the art. Also, the sheet material may be suitably decorated' or inscribed as may be desired.

Referring now particularly to Figs. 5, 6 and 7, the container preferably is formed from a plurality of suitably cut and scored blanks of sheet material, such as paperboard. One blank A (see Fig, 5) preferably is generally more or less rectangular in shape and is provided with fold lines 5, 6, such as scores or other lines of increased flexibility, and fold lines I5 to' define a bottom panel 1, side panels 8 and cover panels 9 hingediy and flexibly connected. The bottom panel 1 and side panels 8 preferably are generally rectangular in shape. The cover panels 9 preferably are of slightly less length, throughout a major portion of their width than the side panels 8, and have inclined edge portions, as at I8, adjacent the score lines 5 to provide corner portions II.

Bottom end flaps 46, bendable about portions of the fold lines I5, extend from the opposite end edges of the bottom panel 1 and side end flaps I1 also bendable about portions of the fold lines I5 extend from the opposite'end edges ofv the side panels 8. The end edges |8 of the bottom end flaps and the inner end edges I9 of the side end flaps are so shaped that the width'of the flaps is reduced, at least at the outer end, for a purpose which will hereinafter appear.

Spaced parallel fold lines 28, 2| and 22 define successively, an innerflange panel 23 connected to a side edge of the cover panel 9, an outer flange panel 24 connected to a side edge of the inner flange panel 23 and an attaching flap 25 connected to the side edge of the outer flange panel 24. The panels 23 and 24 and flap 25 are foldable respectively about the score lines 20, 2| and 22 whereby they can be folded to form rigid flanges, as will hereinafter be more fully described.

A finger hole 28 is provided in either or both of the cover panels 9 to facilitate opening of the container as will hereinafter appear. y

A plurality of end wall blanks B are provided, one of which is illustrated in Fig. 6, The blank B, which may be formed of material similar to the blank A, is provided with a fold line 3|, to define an end panel 30 and a reinforcing flap 32. A hand hole 33 is provided in the end panel 30 at a suitable distance below the fold line 3|.

Referring now to Fig. 7, a reinforcing strip C is constituted by a blank of paperboard material having transverse fold lines 36 defining a central panel 35 and corner flaps 31. l

The blanks are set upand assembled to form the container as follows, although not necessarily in the order ofoperations set forth:

The blank A is folded about the lines 5 and 6, whereby the side panels 8 stand up from the bottom panel 1 to provide side walls. 'I'he 'bottom end flaps I6 andside end flaps I1 are bent up along the lines I5 and extend inwardly from the bottom and side walls respectively. The end wall blanks Bare applied to the inturned flaps and secured thereto by suitable means, as for example, staples 38, as illustrated in Fig. 1 to constitute end Walls and secure the side walls 8 in upright position.

The reduced width of the side wall end flaps permits them to be secured flat against the bottom end flap thereby to provide a neat appearance.

The inner flange panel 23 is folded about the scoreline to a position approximately perpendicular to the corresponding cover panel 9. The outer flange panel is folded about the score 2| to a. position in which it makes an acute angle with the inner flange panel and the attaching flap is folded in the opposite direction into a position lying along the inner face of the corresponding cover panel 9. The attached flap is secured to the cover panel 9 by suitable means, such as staples 38, whereby to retain the flange panels in set-up position, as illustrated particularly in Fig. 3. The flange .panels and the portion of the cover panel 3a extending between the adjacent side edges of the flange panels constitute a triangular construction defining an upstanding flange of inherent rigidity. The ange thus formed stands out from thecover panel without additional reinforcing or stiffening.

The fold lines in the several blanks are formed by spaced parallel score lines 6I) and lIiI which provide an enlarged s core having beads 62, 63 with a flat or somewhat rounded portion therebetween. When the blank A is folded to form the cover flanges in the manner above described, the scoring at the fold 20 provides a substantial bead or ridge 84. Likewise, when the blank is folded along the fold line 2|, an enlarged bead 65 is provided which constitutes a nose having substantial, projecting sides.

'I'he reinforcing strips C are disposed against the inner faces of theY end walls respectively adjacent the top edges. the 'corner flanges 31 being bent aboutthe score lines 36 and lying against the inner faces of the side walls adjacent the corners of the container, and the respective reinforcing anges 32 are folded down inside the container and against the reinforcing strips. Securing means, such as staples 38, secure the reinforcing flaps and. reinforcing strips to each other and to the adjacent portion of the end wall to provide a rigid reinforcing structure at the top of each end wall. The corner flanges 31 are secured to the adjacent side walls to provide corner reinforcing and to assist in securing the side walls to the end walls.

The hand holes 33 preferably are suitably positioned in the end panels 38 so that the lower edges of the reinforcing .strips and reinforcing flaps extend approximately along the top edges of the hand holes whereby the end walls are reinforced immediately above the hand holes and there is no possibility of injury to the end walls at this point. In addition, this reinforcing provides a wider grip for the hands of the person handling the container.

A divider or partitioning means is inserted within the containerand preferably comprises a. plurality of longitudinal partition members D and transverse' partition members E. The partition members D and E are suitably provided with slots, such Aas the slots 42, 43 whereby they can be interengaged to form a cell structure, asY will be understood by those skilled in the art.

. panels t are of such width that the flanges abut' ddl titi

the container.

nicmar @ne or more transverse partition members F are provided which extend from the bottom of the container substantially to the top edges of the side walls. Generally, it is desirable that the partition members D and E extend only partially throughout the height of the container in order to permit ready access to the contents. flowever, where all of the partition members extend substantially throughout the height of the container, it is necessary that all of the transverse partition members be constructed similarly to the high partition members F.

n blanlr suitable for constituting a high partition member F is shown in Fig. 8 and includes 'a member formed from sheet material, such as paperboard, having a suitable number of suitably V shaped slots tb extending inwardly from its low-u er edge for interengagement with the longitudinal partition ymembers D. A notch dt extends inwardly from the upper edge substantially at the center of the blank.

Referring now to Fig. 4, it will be seen that when the cover members t are moved to closed position, the cover danges or portions thereof enter the notch iit. The inclined face il provided by the outer flange panels engage at least a portion of the edges of the notches lit, as indicated at dit, depending upon the relative shapes of the notches and the nanges. Owing to the mutual abutment between the flanges, and to the friction between the flanges and the edges of the notches tt. the cover panels t are held in closed position.

n somewhat diderent construction of high partition is illustrated in Figs. 9, 10 and il, which construction is especially well adapted for se.

curely locking the cover members against undesired opening.

Referring to Fig. li, a. high partition is constructed from a blank G generally similar to the blank F except as to the shape of the notch bil. 'The notch bil is provided with inclined side edges ti so shaped and positioned that when the cover members t are closed, the edges i abut and fit closely against the inclined faces di respectively substantially throughout the length of the latter.

llhe lower portion of the notch is formed with' inturned portions bi dening projections 0r noses ti against which the enlarged beads tb are adapted to engage whereby to loci: the nangea against removal from the notch bt. The cover when in closed position at least at the noses tb and the beads tit, and ths the danges are urged against the edges ti of the notch bt and a substantial locinng edect is obtained.

il. further locking of the cover panels in 'closed position may be obtained by constructing the cover panels of such width that their combined length is slightly greater than "the width of the container, thus providing a condition of unstable equilibrium when the` cover panels are moved into a position perpendicular of the side walls oi In this construction the high partitions G are of such height or are inclined slightly so that the cover members t may be moved into the container slightly'past the position of unstable equilibrium. Thus a condition somewhat similar to a toggle action is obtained. When the 'cover panels are moved through this position of unstable equilibrium and into the container there is a force tending to move them further into the container and opposing opening movement.

lit willvbe understood that the dimensloning of the cover members whereby to provide a condition of unstable equilibrium, as above described, may be employedeither with the form of high partition illustrated in Fig. 8,v as well as that shown in Fig. il.

rlhe cover members are supported in closed position and` prevented against substantial entrance into the container by abutment with the top edges of the high partition or partitions, thus the cover members lie substantially flush with or only slightly below lthe top edges of 'the side and end walls. lit will be noted that the coverpanels are of reduced width substantially throughout their major portion whereby they can enter between the end walls.l However, the corner portions il extend over the ends of the cover walls slightly and thusserve to close the corners of the containers and provide a neat and finished ap pearance.

' When the *cover members are closed the cover naps abut the central portions ofthe end walls and provide reinforcement against inward collapse of the end walls. The reinforcing flap and reinforcing strip provide reinforcement against collapse in a direction transversely of the cover flanges and thus an iii-shaped reinforcing framelilre structure is provided. The multi-ply construction provided by the end walls, bottom end flaps, side end flaps and the reinforcingat the upper end of the end walls provides a reinforced end wall construction.

The inter-engagement between the cover flaps and the high partition or partitions when the cover members are closed prevents bulging of the side walls intermediate their ends. The connection between the corner aps of the reinforcing strips and the side walls provides additional corner reinforcing and provides additional attachment between the end walls and the side walls. The doubly-scored fold lines provide corner beads which stillen and reinforce the edges of the container, and of the cover4 flanges.

The foregoing reinforcing features provide a container or case of extremely great rigidity and strength, which case is capable of withstanding unusually rough and destructive service and is capable of satisfactorily protecting the contents against damage.

Vihile certain novel features of the invention have been disclosed and are pointed out in the annexed claims, it will be understood that various' omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention.
