Description
PARTITION ASSEMBLY WITH INTERLOCKS HAVING GLUED TABS
Background and Summary of the Invention:
This invention generally relates to partition assemblies, and particularly those made of paperboard material or the like having longitudinal and cross strips interlocked to provide a partition assembly having cells into which containers such as bottles, cans, or the like are inserted. More specifically, this invention relates to such a partition a~sembly where the longitudinal and cross strips are held en-gaged by interlocXing slots, and further where a gluedtab is utili~ed at each interlock of a cross strip with a longitudinal strip to securely lock the strips .

~63~33 together.
Partition assemblies having interlocking longitudinal and cross strips are well known in -the art. E~arnples are shown and described by U.S. patents 4,000,845 (issued ~anuary 4, 1977 to Zeller); 3,948,435 (issued April 6, 1976 to Palmer); 3,942,337 (issued March 9, 1976 to Engle); and 3,942,709 (issued March 9, 1976 to Gepfer). It is also known in the art -to use glued flaps, tongues or tabs in a partition assembly.
George U.S. patent no. 2,549,801, issued April 24, 195i, discloses a partition assembly where khe partition strips are zig-zag folded and joined to adjacent zig-zag folded strips by means of glued tongues. However, the tongues are not part of an interlock for joining cross strips.
Gepfer patent 3,942,709, owned by the same assignee as the presen-t invention, discloses an interlocking partition with glued end flaps to stabilize the partition, but does not disclose the use of glued tabs at the interlocks.
Martin U.S. patent no. 4,226,357, issued October 7, 1980, discloses a partition having glued tabs, but the partition is formed from a single blank. The tabs are not part of an interlock for interlocking cross strips.
Other examples of partition assemblies are shown by U.S.
patents 1,137,732 (issued May 4, 1915 to Alfred); 3,446,412 (issued May 27, 1969 to Stark); 3,640,445 (issued February 7, 1972 to Durham); and 4,219,146 (issued August 26, 1980 to Skaggs et al.).
The present invention specifically relates -to partition assemblies having interlocking ~, ~
''' longitudinal and cross strips, and in accordance with the inven~ion the interlocks have ylued tabs to securely interlock the strips. The interlock includes a first slot in a longitudinal strip and a second slot in a cross strip, one of these slots having a tab~
side surface of the tab is adhered to a side wall of the strip having the other slot. The tab is foldable generally along the line of intersection of the longitudinal and cross strip to accommodate unfolding of the partition assembly between collapsed and expanded positions.
To assemble the partition, the longitudinal and cross strips are each formed with their respective slots. In a preferred embodiment of the invention, the cross strips have the slots with tabs. The longi-tudinal strips that form each partition are fed along a conveyor on their side edges such that the strips are parallel and vertically oriented. The cross strips are formed from a continuous web. The slots having the tabs are die cut for each cross strip as the web moves past the die station. Preferably, then adhesive is applied to one side of the tabs, and the strip i9 severed Erom the web. With the longitudinal strips forming each partition in transverse alignment and with their slots opening to their upper edges, the severed cross strip is fed downwardly orthogonally to the longitudinal strips such that its slots engage :, ~i3~33 with aligned slots oE the parallel longitud:Lnal s-trips to interlock the cross strip with each longitudinal strip. '~'his is a con-tinuous proces.s such as thclt the cross stripc; are fed downwardly in succession to form each partition assembly after the longitudinal strips for a par-ti-tion assembly are positioned as previously explained.
After each par-tition assembly is formed, it is collapsed from its fully expanded confiyuration to a collapsed configllration in a direction such that the glued sides of the tabs engage the side wall of the longitudinal strip or strips to become adhered thereto. The collapsing operation may be done by hand, or with automated equipment. The collapsed par-ti-tion assemblies are collected into bundles for shipment to the customer.
When such partition assembly is unfolded or expanded for use by the customer, the cross strips again become orthogonal to the longitudinal strips, but the tabs remain glued to the longitudinal strips such that the tabs becomes folded generally along the line of intersection of the strips. To facilitate this folding of the tab, the base of the tab may include perforations, slots or other suitable means.
. _ . . ...
~.Z6~3~33 By means of the glued tab interlock, the present invention provides a partition assernbly with interlocking longitudinal and cross s-trips where the engagement betw0en the strips is very secure and pre-vents inadvertent separation of the strips during handling and the automated operations to which the assemblies are subjected, and yet provides a partition which is easy to assemble.

etailed Description of Preferred Embodiments:
With reference to the drawing, there is shown a partition assemb]y 10 of the present invention having cross partition strip~ 12 and Longiludinal partition strips 14 preferably of paperboard material. Figures 3 and 5 show the partition assembly in the fully open configuration. It is to be understood that partition assemblies of the type to which this invention relates are fox insertion in boxes and define generally rectangular cells 16 into which bottles, cans, and other articles are placed for shipment.
Each cross strip 12 has one or more slots 18 having a slot portion 20 with a flared opening 22 at a side edge 24 of the strip. From the ~lared opening 22 the slot portion 20 has a side edge 26 extending from the flared opening inwardly toward the opposite side edge 27 to a bottom edge 28, and an edge 30 extending from the bottom edge back toward the flared opening.
The edges 26 and 30 are parallel and are orthogonal to the side edge 24 of the strip. The gap between the edges 26 and 30 is ~lightly wider than the thickness of the longitudinal strip 14.
The slot 18 also includes a generally rec-tangular opening 32 into which extends a generally rectangular tab 34. As shown in the drawing, the tab 34 is spaced and free from the opening on three sides .
3~3 thereof, al]owing the tab to fold alony its base 36.The base of the tab is generally in alignment with the slot portion 20.
Each longitudinal strip 14 has one or more slots 40. Each of the slots 40 has a flared opening 42 at a side edge 44, an edge 45 extending inwardly therefrom toward an opposite side edge to a bottom edge 47, and an edge 48 extending from the bGttom edge back to the flared opening. The edyes 45 and 48 are parallel and generally orthogonal to the side edge 44 of the strip. The gap between the edges ~5 and 48 is slightly wider than the thickness of the cross strip 12.
A side surface 50 of the tab 34 has adhesive applied thereto. The cross and longitudinal strips are interlocked by engagement of the slots 18 with the slots 40 such that the bottom edge 28 of the slot portion 20 engages the bottom edge 47 of the slot 40.
The depths of the slot portions 20 and slots 40 may be selected such that when fully engaged, the side edges of the cross strips and the side edges of the longitudinal strips are in alignment. While the location of the tab 34 is shown to be at a generally centralized area of the strip 12, it could be located to be closer to, or even at, one of the side edges.
Figure 5 shows the partition assembly in the fully assembled configuration with the longitudinal and cross strips fully interlocke-1, and with the tabs 34 folded over with the sides o~ the -tabs having ~he adhesive adhered to side walls 52 of the longi~udin~l strips. To Eacilitate the fol~iny o~ the tabs 3~, each of the tabs has perforations 54, as shown in Figures 2 through 4, or slots 56, as shown in Figure 6, near its base. Preferably, the perforations 54 are generally in alignment with the edge 30 of the slot portion 20, or in the case of the slot 56, the 610t iS
in alignment with the slot portion 20.
To assemble the partition assembly shown in the drawing, the longitudinal strips are brought into parallel relation with their slots transversely aligned, and with each longitudinal strip resting on its side edge 46 such that the slots open upwardly.
The spacing between the parallel longitudinal strips is the same as the spacing between the slots 18 in the cross strips. Preferably, the cross strips are formed from a continuous paperboard web. The web is fed past a die station where the slots 18 are cu-t. Next, adhesive is applied to one side surface of the tabs 34. Then, each cross strip is severed from the web and driven downwardly into interlocking orthogonal engagement with the longitudinal strips such -that the notches 18 engage the notches 40~ This stage of the assembly is shown by Figure 3 where the partition is fully expanded with the cross strips orthogonal to the 3~3~
longitud.inal strips, and wi~h the tabs 34 sti11 extending into the openings 32.
Next the partition assembly is ~o:Lded or collapsed to ~he configuration shown :in Fiyure 4. The partition i8 co.llapsed in a direction such that when fully collapsed, the adhesive sides of the tabs engage the side walls 52 of the longitudinal strips ~or adherence thereto. The partition assembly is bundled, along with other partition assemblies, in the collapsed configuration for shipment to the customer.
Upon use of the partition by the customer, the partition is unfolded from its collapsed configuration shown in Figure 4 to a fully expanded configuration as shown in Figure 5. Upon unfolding the partition, the tabs 34 fold generally along the lines of intersection of the strips, such as along the perforations 54 or slots 56, to move out of the openings 32 and remain adhered to the side walls of the longitudinal strips.
The glued tabs provide a very secure interlock between the longitudinal and cross strips with ease of manufacture.
There are various changes and modi~ications which may be made to applicant's invention as would be apparent to those skilled in the art. However, any of these changes or modifications are included in the teaching of applicant's disclosure and he intends that his invention be limited only by the scope o~ the cla~ms ap~e~ded hereto -
