signor to Unipak Cartons Ltd., Vancouver, British Columbia, Canada Application June 7, 1954, Serial No. 434,915

1 Claim. (Cl. 2ML-185) My invention relates to improvements in cartons.

The particular object of the invention is to provide a carton fitted with a concealed handle by which the carton and its contents can be carried.

Other objects are to provide that the handle can become accessible by the simple means of slitting a portion of the binding strip which is used to seal the carton after it has been lled with the bottles, jars or other articles, and also to provide a carton which can be returned with the handle undamaged and concealed for reuse in packing new articles and then resealed by another adhesive binding strip.

A still further object is to provide a handle component which also serves as a dividing wall in the formation of the ller cells within the structure.

Other objects will devolop as the specification proceeds.

Referring to the accompanying drawings:

Figure 1 is a perspective view of the finished invention showing the handle withdrawn to carton carrying position.

Figure 2 is a plan view of the carton blank.

Figure 3 is a perspective view of a filler member.

Figure 4 is an elevational view of the handle member.

Figure 5 is a plan view of the assembled parts prior to the folding of the blank.

Figure 6 is a plan view of the completely finished carton in the knock down state ready for sale and shipment to the user.

Figure 7 is a perspective View, part broken away, of the carton opened out ready for filling with merchandise.

Figure 8 is an enlarged sectional view showing the disposition of carton and filler members as the handle member is being interleaved with said filler members.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral 1 indicates a carton blank which is creased to provide

side walls

2 and 3,

end walls

4 and 5, top end closures 7,

top side closures

8 and 9, bottom end closures 10 and bottom side closures 11. Each of the top side closures are cut back to form recesses 14 and at the base of one of these recesses a finger gap 15 is provided. The free end of the site wall 3 is provided with an elongated tab 17 which is adapted to be united with the free end of the end wall 5 by a pressure setting resin glue which is preferably used throughout the manufacturing of the carton to knock down form. Glue is applied to the area 18 of the slide wall 3 and a similarly positioned area of side wall 2.

The filler structure 20, see Figure 7, is formed of filler members 21, see Figure 3, and a handle member 22. The filler members 21 are strips of material which are creased as at 24 to dene end folds 25 which are adapted to be bent only when the carton is opened into box form as in Figure 7. Each filler member is provided with a Vshaped notch or mouth 27 having at its base a parallel sided gap or throat 28. The end folds of the filler strips are coated with glue, so that when they are laid down upon one of the areas 18 and the parts pressed together a proper bond will be formed. The handle mem- 2,727,653 Patented Dec. 20, 1955 ber 22 consists of a hand grip 29 and a wall portion, which portion is provided with a plurality of vertical slots 31, each having an offset side edge 32 which projects beyond the normal plane of the handle member. The slots 31 are considerably longer than the vertical dimension of the filler members 21.

In making up the carton, a number of filler members are laid in overlapping arrangement upon the glued area 18 of the side wall 2, with their free ends extended to the right of Figure 5 and being creased as before described with their free ends slightly elevated above their intermediate parts as shown in Figure 8. A handle member is laid down upon said filler members with the offset edges 32 of the slots 31 of the wall portion extending diagonally, s0 that as said handle portion is moved to the left of Figures 5 and 8, each free end portion of the filler members 21 will pass through one of said slots. When in the position above described the upper end of the grip 29 will be slightly above the upper limit of the side wall 2, but may be aligned therewith by moving the handle members so that the upper edges of the vertical slots 31 will enter their respective notches 27 and be lodged in the gaps 28. To complete the knockdown carton it is now only necessary to fold the side wall 3 over onto the filler members and the end wall 5 over onto the glued tab 17 and press them together to bind all the glued parts to their counterparts.

The purchaser opens up the knock down carton to rectangular form and closes its bottom portions and the carton is then filled and sealed with a glued tape 35.

When the purchaser of a filled carton wishes to use the grip 29, he slits the tape 35 and inserts a linger through the finger gap 15 and lifts said handle until the lower edges of the slots 31 engage the under edges of the filler members.

What I claim as my invention is:

A carton having sides and a bottom wall, a filler structure within the carton, said ller structure having a plurality of iiller members connected at opposite ends to opposing side walls, and a slidably extensible handle member adapted to be normally wholly enclosed in the carton, said member being supported by the filler members and serving to define article receiving spaces on both sides of the handle member and between the liller members, said filler members having medial slots on their upper edges, and said handle member having a plurality of vertical slots closed at their lower and upper ends, said filler members extending through the vertical slots and said medial slots being adapted to locate the handle member lengthwise of the ller members when said handle member is in normal position, the lower marginal edges of the vertical slots being adapted to bear upwardly onto the lower edges of the filler members to support the carton when being carried by the handle members.
