' v ARTHu/eJT WEISS ATTORNEYS 2,806,643 FOLDING PAPERBOARD CENTER HANDLE CARRIER Arthur J. Weiss, Bergenfield, N. 1., assignor to Continental Can Company, Inc., a corporation of New York Application May 25, 1954, Serial No. 432,090 3 Claims. (Cl. 22952) The invention relates to folding paperboard center handle carriers or cartons of the type in which the handle extends through the top, or cover, of the carrier.

Center handle paperboard carriers or cartons of the type described ordinarily are constructed from paperboard blanks in which the handle constitutes an integral part of the blank. One of the most serious drawbacks of such devices is that they are difiicult to set up for use due to the rather complex manipulations involved in folding the handles and bringing them into carrying position. in many such carriers it is necessary to fold the handle and then to feed it through a slot. Frequently it is necessary also to supplement this or other folding steps with special fastening operations such as stitching of flaps, etc. with metal staples and the like. Also there is the problem that, once the handle has been folded into form, the carrier cannot be knocked down flat for shipment to the packager, retailer or other initial user. And there is the still further problem of devising any simple mechanized operation for setting up such carriers, and as a consequence the user must do most of the job by hand, even to the steps of individually folding and setting up the handles.

It has been an object of my invention to devise a carrier or cart-on construction which alleviates the fore-v going problems, which is particularly well adapted to the production of center handle carriers that can be produced in flat folded form withhandles already formed and secured in carrying position, and which can easily be folded and glued with the use of conventional types of high speed folding and gluing machines. My carrier can be converted from its fiat folded form as received from the carton manufacturer to its erected form by the simple manipulation of squaring up the sides, and, in cases where end closures are desired, tucking the end flaps together. Other objects and advantages of my invention will appear as the description proceeds.

In accordance with my. invention a folding paperboard center handle carrier comprising a bottom panel, two opposed side wall panels and atop panel together forming a tubular body, has its top panel made in two sections extending respectively from the two opposed side wall panels with the two top panel sections overlapping near the center of the carrier, and a handle formed as an extension of one of the top panel sections includes a glue flap which lies below the top panel and is adhesively secured to the underside thereof, the overlapping portions of the top panel sections being adhesively secured together. The handle is hinged to one of the top panel sections along a line which is parallel to the overlap and inwardly from the edge of such top panel section. The glue flap lies partly below overlapping portions of the top panel sections. In my preferred construction the top panel section to which the handle is attached, has a recess extending along its edge, and the handle has its side strips extending from the base of such recess near its ends.

An important aspect of this construction is its adaptability to manufacture in flat folded form with the use of a conventional type of high speed folding and gluing maited States Patent Patented Sept. 17, 1957 chine by performing the following steps: folding the handle flat with its glue flap adjacent the inside of the adjoining top panel section, folding such panel section flat against its adjoining side wall panel while at the same time reversely folding the handle flat against the outside of its adjoining top panel section to bring the ends of the glue flap underneath the respective ends of the recess from which the handle extends, applying an adhesive to the inside of the edge of the other top panel section and then folding it, together with its adjoining side wall, fiat against the bottom panel to bring its glued edge into juxtaposition with the exposed area of the handle glue flap and with the edge portions of the first top panel section which are in line with the glue flap, and finally pressing the juxtaposed glue areas together.

in the drawings, wherein I have illustrated the best mode contemplated by me of carrying out my inventron:

Fig. 1 is a perspective view of a carrier, suitable for use as a hatbox and the like, embodying my invention in its preferred form.

Fig. 2 is a perspective view of the inside of the blank from which the carrier of Fig. 1 is formed. This view illustrates the first step in the production of the flat folded carton.

Fig. 3 is a view similar to Fig. 2 illustrating the second step in the production of the flat folded carton.

Fig. 4 is a similar view illustrating the final step in the production of the fiat folded carton.

Fig. 5 is an inside view of the blank.

Figs. 6, 7 and 8 are detail vertical cross-sectional views illustrating the first handle folding step.

Figs. 9, l0 and 11 are detail vertical cross-sectional views illustrating the second handle folding step as performed in conjunction with the first body folding step.

Figs. ll, 12 and 13 (Fig. 11 having been mentioned previously) are detail vertical cross-sectional views to illustrate the final body folding step.

Referring to Figs. 1 to 5 inclusive, my preferred carrier or carton construction is shown as comprising a bottom panel 14, two opposed

side wall panels

15 and 16, and a top panel denoted generally as-17. These several panels together form a tubular body. The top panel 17 comprises two

sections

18 and 19 extending respectively from the two opposed

side wall panels

15 and 16. Top panel section 19 has a recess 20 extending along the central portion of its edge, and a folding double handle 21 has its side strips 22 extending from the base of recess 29 near the respective ends thereof. The other top panel section 18 has recesses 23 in its edge to receive side strips 22 of the handle. Handle 21 includes a glue flap 24 which extends beyond the ends of the central recess 20 in a longitudinal direction. Thus the glue flap has end portions which overlap portions of the top panel sections (see Fig. 3) and a central exposed area available for gluing to the edge of the top panel section 18.

As we have seen, the panels and

panel sections

14, 15, 16, 18 and 19 together form a tubular body. If a closed end carrier or carton is desired, suitable end flaps may be provided for this purpose, such as the interlocking flaps 2529 inclusive. One conventional form of such interlocking flaps is shown in the drawings, but as the construction and operation of such end flaps are well known and form no part of the present invention, further detailed description appears to be unnecessary. However, it may be noted that these flaps are shown in their closed and interlocked relationship in Fig. 1. Other types of end closure flaps may be used according to the particular needs to be served.

The several panels and flaps which have been described are defined by score lines or other forms of fold lines as well known in the art to which this invention pertains,

such fold lines being indicated generally at 3033 for example.

Referring more particularly to Figs. 2 to 13 inclusive, I shall now describe the steps of forming and gluing the fiat folded carrier from the blank of Fig. 5. The first step, illustrated in Figs. 2, and 6 to 8 inclusive, comprises folding the handle 21 flat with its glue flap 24 against the inside of top panel section 19. Next the top panel section 19 is folded fiat against its adjoining side wall panel 16 while concurrently folding the handle flat against the outside of top panel section 19 to bring the ends of the glue flap 2.4 underneath the respective ends of recess 20 of top panel section 19. This combined operation will best be understood from a comparison of Figs. 9, and 11, having regard to the movements indicated by the arrows in these views. Top panel section 19 swings in a counterclockwise direction as here viewed, while the folded handle 21 remains horizontal, or nearly so. This is an operation which can be performed easily on conventional folding and gluing machines in which the paperboard blanks are fed through the machine in a direction parallel to the

fold lines

31, 32 and 33. The glue flap of the handle is turned through 180 relative to top panel section 19 while the ends of the flap remain on what is to be the underside of top panel section 19. Thus the ends of the flap are brought automatically into the desired final relationship without any special tucking operation. At some time before the next folding step, the adhesive, such as glue, is applied to the inside of the other top panel section 18, adjacent the edge of such section, as indicated by the stippling at 34 in Fig. 3. In the next folding step, top panel section 18 and its adjoining side wall panel are folded flat against the bottom panel 14 to bring its glued edge into juxtaposition with the exposed area of the handle glue flap 24 and with the edge portions of the top panel section 19, and the juxtaposed glue areas are then pressed together to complete the formationof the flat folded carrier or carton as shown in Figs. 4 and 13. This is the form in which the carrier or carton is shipped from the box manufacturer to the packer, retailer or other user. It will be observed that in this form the handle 21 is ready for use without any further manipulation.

In addition to the advantages of ease of manufacture of the flat folded device and the ease of setting it up for use, my construction has the further advantage that the glue flap of the main body of the carrier is in line with the handle so as to provide the reinforcement of a double thickness of glued paperboard stock where strengthening isof the greatest importance.

The terms and expressions which .I have employed are used in a descriptive and not a limiting sense, and I have no intention of excluding such equivalents of the invention described, or of portions thereof, as fall within the purview of the claims.
