. It) Ciaims. (Cl. 229-416) This invention relates to carriers and more particularly to an improved collapsible bottle carrier for handling a plurality of bottles or multiple units of bottle cartons. The bottle carrier embodied by the present invention is particularly adapted for handling, displaying and marketing multiple cartons of bottles or the like, and possesses characteristics particularly satisfying as regards strength, ease of storage, cost and attractiveness in a carrier intended to perform such functions.

The bottle carrier is characterized in that it comprises a lightweight, collapsible assembly including only a one piece folded paperboard body and wire rim means. The one piece folded paperboard body includes transverse parallel end and divider panels, and a bottom section joining the end and divider panels along carrier collapsing fold lines. The wire rim means is pivotally attached to each end and divider panel, and spans the panels in a paralell relationship with respect to the bottom section of the folded paperboard body, thereby maintaining the panels in fixed parallel relationship with respect to one aonther whether the carrier is erect or collapsed. A carrier handle formed integral with either end or divider panels serves also as a positive and direct carrier erecting means whereby force applied to the carrier handle to rotate the panel including the handle is transmitted directly to the rim means and in turn to all the other panels to which the rim is attached to cause similar rotation thereof.

Hitherto bottle carriers of the present collapsible type have been constructed and assembled from separate panel, bottom, end and handle sections, as for example in Glenny, US. Patent No. 2,551,262. Erection of this type of carrier is not possible by merely rotating the handle of the carrier and the present combination of structural elements provides this handle erecting func tion based upon the novel structural elements.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

FIGURES l1 and 12 are perspective views of modified forms of the carriers of FIGURES 6 and 7; and

FIGURE 13 is a perspective view of the carrier of FIGURE 11 with a grid to provide cells.

In FIGURE 1 the material of the blank sheet 11 is shown in folded condition to form body Iii and in such configuration comprises transverse, parallel end panels as, transverse divider panel 28 parallel to and disposed between the end panels 26, and bottom section 30, the bottom section in this instance comprising blank panel sections 32, also shown in FIGURE 3. The fold lines 15 at the intersection of end panels 26 and panels 32 comprising bottom section 3%, and the divider panel fold lines 13 at the intersection of divider panel 28 and panel bottom section 3b comprise carrier collapsing fold lines for enabling the erected carrier as shown in FIGURE 1 to be collapsed to the position shown in FIGURE 4 by allowing the end and

divider panels

26 and 28 to be rotated relative to the bottom section 30 about said fold lines 15 and 12-3 respectively, in a manner to be more fully described below. It will be noted that the end and

divider panels

26, 28 of body 10 comprise double layers of blank body material since they are formed by folding blank panel sections 26, 28' of sheet 11 back upon themselves along fold lines It and 19, respectively. The panel sections 26 and 28' forming the end and divider panels as and 28 are secured together by suitable means such as mechanical fasteners 34, by adhesive bonding (not shown), or some other suitable means. In bonding the panel sections or layers as comprising end panels 26 along fold lines 14, which, as can be seen from FIGURES 1 and 2, form the free upper edge portions of end panels 26, apertures 36 are formed which extend transversely along the upper edges of panels 26. In securing the panel section 26 together by mechanical fasteners or other means, care must be taken that the apertures 36 are not closed by bonding the panel sections 26' complete.y together up to fold line 14. In securing together the panel sections or layers 28' comprising the divider panel 23, an aperture 38 is termed transversely of said divider panel by leaving an area of each panel section 28' unsecured to the other. The aperture 38, as will be apparent from FIGURE 2, lies in the same horizontal plane a apertures 36 in end panels 26 of the folded blank Iii.

The divider panel 28 in the embodiment of FIGURES 1, 2, 3 and 4 includes a free upper area 40 which extends above the plane of the apertures 36, 33, and a handle aperture 41 extending through both blank layers of the divider panel 28 is formed in this area by the juxtaposition of apertures 22 provided on either side of fold line 19 of blank sheet 11, as seen in FIGURE 3. The

apertures

36 and 38 in

panels

26 and 28 comprise rim receiving apertures which receive certain portions of rim 12 in the manner to be described below.

As seen best in FIGURES l and 2, the carrier embodied by the present invention includes a wire rim means 12 which is adapted to reinforce the carrier structure, and maintain the end panels 26 and divider panel 28 in parallel relationship at all times, whether the carrier is erect or collapsed. This is accomplished by pivotally attaching the wire rim means 12, which in this embodiment is a continuous length of longitudinally rigid wire or rod, to the end and

divider panels

26 and 28 in such a mannerthat the wire rim-to-panel' joint at each end and divider.

' 3 I 7 panel permits relative rotation between the rim andpanel about a transverse axis parallel to the bottom panel 30, while non-rotational relative movement between each of the panels and rim is restrained. That is, the manner of attachment of the rim 12 with the folded end and

divider panels

26 and 28 oftthe body issuch that each

panel

26, 28 may be rotated with respect to the bottom panel 30 .from its erect position asv shown in FIGURE 1 to its collapsed position as shown in FIGURE 4 about its collapsing fold line, the collapsing fold line for panelsp26 being fold lines 15, the collapsing fold line for divider maintaining the carrier in erect position, and transporting of the carrier all may be readily accomplished by means of the handle provided in the foldedend or divider panels of thetcarrier. V J

' Accordingly, in the embodiment of FIGURES 1, 2 and 4, positive erection, collapsing and transportation of the carrier shown allmay be accomplished by grasping dipanel 28 comprising fold lines 18, without mechanical interference with such rotation being caused by the'rim member 12. a At the same time, the rim 12, being attached a to the erected

end anddivider panels

26, 28 at points lying in the same horizontal plane parallel to butspaced r from the bottompanel 30 as seen clearly inFIGURE 2, maintains the end and divider panels in parallel relationship throughout their rotational displacement about their collapsing

fold lines

15 and 18, respectively.

Considering in detail the structural relationship between the assembled rim 12 and body 10 of the carrier embodied by FIGURES l, 2 and4, such structure being essentially typical of all embodiments of the present invention illustrated by way of example, the rim 12 as seen in FIGURE 1 includes transverse portions 45 which extend transversely through the apertures 36 in end panels 26, and a transvider panel 28 through aperture 41 in body 10 formed by apertures 22 in blank sheet 11 as shown in FIGURE 3,

and exerting necessary rotational forces, upon the panel'28; V i a In FIGURE 6 there is shown anothertcarrier embodiment of the present invention. In this instance the onepiece carrier body-10 is formed from a blank sheet '11 cut and sc-oredasshown in FIGURES. It will be readily apparent that in all essentials theblank sheet of FIGURE 5 is'substantially the same as the blank of FIGURE 3 used in forming the carnier of the FIGURE 1 embodiment except that the blank 11'.is cut and scored ,to allow its -being folded so as to form end panelsf26 with free upper areas. 40' having handle apertures 41' therein in the same manner as, the divider panel 28 of the FIGUREl carrier embodiment.

' themechanical fasteners 34 securing the body material verse portion 46 which extends through" aperture 38'provided in divider panel 28." Sincethe apertures 36 and 38 are disposed'in the samehorizontal plane when the carrier is in erect position as seen in FIGURE 2, the rim 12 forms a rigid interconnection between the folded end and

divider panels

26, 28 in a plane horizontalto but spaced 7 from the bottom panel 30. As stated above, the aper tures 36 each are formed specifically in this instance to freely rece'ive the rim portions 45, and, when so assembled, compr'ise pivotal rim-to-panel joints which allow pivotal motion between panels 26uand 28. At thesarne time, non-pivotal motion between the panels and rim in the plane of each of the panels is restrained by reason of interference between the

rim portions

45, 46 and the body material layers 26, 28' comprising thepanels 26 and 28, the fastening means 34 joining the body material layers 26f,28' and, in the-case of the end panels 26,-the folded over body material at fold lines 14. In referring to nonrotational motion betweeneach of thepanels andv rim in theplane of each panel, it is, of course, to be understood that this refers to relative motion of the rim along the line of separation of the blanklayers 26', 28' in a vertical direction as the carrier is viewed in FIGURE 2. Relative motion of the rim 12 in a transverse sense relative to the panels'26 and 28 is always prevented by reason of the configuration of the rim 12 as'is'clearly apparent from FIGURE 1, for example. a v

, An important f eature of the carrier of the present jn vention lies in the provision of a folded end or divider panel having a free portion'or area extending above or beyond the rim-to-panel joint, that portion of the panel including an integral handle means; For example, as

seen in FIGURE 1, the jdivider panel 28, includes a free upper area 40 which extendsabove the joint between the rim 12 a'nd panel 28, the area 40 "having a handle aper1 'ture 41 extending t herethrou'gh The advantage of such a feature lies in the fact that the carrier of the invention may be readily raspedat the handle whilein the collapsed position, as seen in FIGURE 4, for. example, and erected layers 26' comprising the endpanels 26 restrain non-rotational relative motion between the end panels and rim means'12 in the plane of panels 26, while in the caseof the divider panel 28, non-rotational relative motion between the divider panel 28 and rim 12. in'the plane of panel 28 is restrained on one side by the body material folded, over upon itself along foldflline 19, and on'the other side :by the mechanical fasteners securing together 'the body material'layers 28" comprising panel 28.
