INVENTOR HUGH T. CAMERON Ew mzw United States Patent 3,258,152 CARTON WITH SLIDABLE, CON CEALED HANDLE Hugh T. Cameron, St. Bruno, Quebec, Canada, assignor to Bathurst Power & Paper Company Limited, Montreal, Quebec, Canada Filed June 19, 1964, Ser. No. 376,418 3 Claims. (Cl. 220-105) This invention relates to a partitioned container made from paperboard, including boxboard and other similar containerboards.

Vast quantities of containers made from paperboards are used annually for shipping bottled and canned beverages and the like. The constructions employed are legion but it is usually a prime object of a manufacturer to achieve a strong container with a minimum amount of paperboards that can be efficiently used in modern packaging methods. The present invention is thought to be novel and is remarkable in the extent to which it achieves these sought after objects.

Generally speaking, a container according to the present invention is, with the exception of the handle, formed from a single blank of paperboard. It has a longitudinally extending divider that is hinged to one of two bottom panels. The handle is carried by the divider and is slidable with respect thereto to appear and disappear through an opening in the top wall. The invention will be clearly understood after reference to the following detailed specification read in conjunction with the drawings.

In the drawings,

FIGURE 1 is a view showing the blank from which the body of the container according to this invention is made, and the blank of a handle therefor.

FIGURE 2 is a perspective illustration of a container according to this invention open at one end.

FIGURE 3 is a view along the line 33 of FIGURE 2, and

FIGURE 4 is an illustration showing the manner in which the handle is carried by the divider.

In the drawings, the numeral generally indicates a blank of corrugated paperboard according to this invention from which a container is formed. It has score lines and openings that permit it to be assembled into the end-opening, handle type carton illustrated in FIG- URE 2. In the specification, similar numerals will be used to designate the panels in the blank and in the assembled container.

The blank 10 comprises atop wall panel 12, a firstside wall panel 14, a secondside wall panel 16, a firstbottom wall panel 18, a secondbottom wall panel 20, adivider member 22, abottom securing member 24, ahandle retaining flap 26, two divider retainingflaps 28 and 30 and endwall closure flaps 32, 34, 36, 38, 40*, 42, 44, 46, 48 and 50.

Thenumeral 52 generally refers to a handle member that is carried by the divider member as will be referred to later in more detail.

To assemble the blank and handle member, shown in FIGURE 1, into the container illustrated in FIGURES 2 and 3, one first mounts thehandle member 52 with respect to thedivider member 22. This is done folding themarginal edge portion 26 of thedivider member 22 about itself along the scoredfold line 27. A longitudinally extendingslot 29 is formed in thedivider member 22 to freely admit thegripping portion 54 of thehandle 52. Thehandle 52 hasshoulders 56 at the base of thegripping portion 54 thereof which are adapted to engage with thefirst divider member 22 at thefold line 27 to limit the extension of thehandle portion 54 through theslot 29. The end portions of the marginaledge flap portion 26 of the divider member are adhesively secured in the folded over relationship that is illustrated in FIGURE 4- to retain the handle.

It will be apparent from an examination of FIGURE 4 that the handle generally indicated by thenumeral 52 can be slid from the position illustrated in FIGURE 4 wherein the gripping portion thereof is juxtaposed to thedivider member 22 to the dotted line position illustrated in FIGURE 4 wherein thegripping portion 54 is extended beyond thefirst divider member 22, the extension being limited by theshoulders 56.

Thehandle 52 is also made of corrugated paperboard and it will be noted that the grippingportion 54 is formed with an appropriate opening through which the fingers can be inserted for convenient handling. The opening also has atab 58 that can be bent over to retain the gripping portion in an extended position on the exterior of the carton.

It will be noted that the depth indicated by the dimension 60 of thehandle 52 is slightly smaller than the depth of thedivider member 22. Thedivider member 22 extends for substantially the full depth of the carton and in use is glued along its bottom marginal edge to thebottom securing member 24. The handle slides between the divider panel and the bottom securing panel and its lower travel is determined by the glue line. The handle must have a depth, however, such that one can always easily grip the handle when it is in a retracted posi tion by inserting ones fingers through the top opening 62.

Once thehandle section 52 has been assembled with respect to the blank 10, the carton can be formed. To do this, thetop wall 12,side wall panel 16,bottom wall panel 20 and securingmember 24 are folded so that their cross section is rectangular and secured in this position by means of thetabs 28 and 30 on the longitudinally extending edges of themember 24.Tabs 28 and 30 on thebottom securing member 44 are adhesively secured to the underside of thetop wall 12.

Theside wall 14,bottom wall panel 18,divider panel 22 andtop wall 12, are also folded to assume a rectangular disposition with respect to each other in cross section as illustrated in FIGURE 3. It will be noted that the upper edge of thedivider panel 22 is slightly below the upper edge of thebottom securing panel 24.

In this position, the upper edge of thedivider panel 22 underlies the longitudinally extendingslot 62 in thetop wall 12 of the carton.Slot 62 has a length slightly larger than the length of thehandle portion 54 of thehandle 52 and has an enlarged portion in the centre through which one can insert ones fingers to grip the upper portion of thehandle 58 and pull it through theslot 62 to assume an operative position as illustrated in FIGURES 2 and 3. In this position, theshoulders 56 are engaging in the fold line of the folded overmarginal portion 26 of thedivider panel 22. Thetab 58 can be bent laterally to prevent unwanted disappearance of the handle into the slot again.

As indicated above thedivider panel 22 and thebottom securing panel 24 are adhesively secured together along their lower marginal edge portions to maintain the securing panel rigid with respect to thedivider panel 22 and hence with respect to thebottom panel 18. Securingpanel 24 is formed with an extension above the adhesively secured portion which hastabs 28 and 30 thereon for locating the component parts in their relative proper positions.

The unit is capable of considerable variation especially in this particular area. Locatingtabs 28 and 30, for example, could be formed on upward extensions of the extreme end portions Olf the divider panel in which case it would not be necessary to carry thesecuring panel 24 substantially beyond its area of adhesive attachment withdivider panel 22 near its bottom.

The end walls are formed by folding over first theflaps 36 and 32 and 40 and then flaps 34 and 38 for one end wall. The container is adapted to be filled through an end wall and, in use, is filled before the end wall flaps at the other end are closed. The end flaps are maintained in a closed position by application of an adhesive to the overlapping parts thereof.

The container, when assembled and filled, has remarkable strength. It is economical from the point of view of materials used and operations in its manufacture and it is simple to assembled.

Once filled and sealed, the contents are removed by breaking an opening delineated .by the weakenedperforated line 63. A thumb hole is formed at the perforated line as at 64 to start the opening. The adhesive securement at thetabs 28 and 30, very useful in the assembly of the carton, is broken as the opening is made. The opening has been indicated in the top wall but openings could be made in side walls for the same purpose.

It is not intended that the invention should be limited to the foregoing specific embodiment illustrated.
