Abstract
Abstract In a method of packaging, a generally rectangular cross-section tubular carton is used, formed of stiff packaging material, having at least one open end provided with a flap connected to each edge thereof. The flaps are folded inward and overlapping flaps are bonded to underlapping flaps to form a closed end. In the invention, a flap on one end edge, adjacent a point where the item or items packaged offer no resistance to inward movement of the flaps, is folded inwardly after the folding inwardly of the flaps on the side edges adjacent said end edge and is bonded to the exterior thereof. The method is useful for packaging long-necked beer bottles or other items offering resistance to inward movement of the flaps at a point opposite the said one end edge.
Description
~2~317~
This inve~tion relat~s to carton blanks, to metho~s of packaging using them, and to the folded and assemble~ cartons thus produced, and more particularly though not excl~sively to tubular cartons of rectangular cross-section having an opening at one or both ends which in use is closed by overlapping flaps connected on the edges of the opening and bonded to the exterior of the flaps which they overlap. The invention is more particularly al-though not exclusively concerned with cartons used for packaging items which offer resistance to inward movement oE the flaps ln adjacent one zone of the opening but which offer substantially no resistance to such movement adjacent an opposite zone.
In the brewery industry, it is known to use tubular cartons of elongated rectangular cross-section into which beer bottles are loaded by being introduced through one or both ends of the carton. These cartons have been employed for packaging rela-tively short approximately cylindrical bottles, in a packaging procedure consisting of folding inwardly the flaps which for the sake of convenience of description may be termed "end flaps"
connected to the shorter sides of the cross-section to an inwardly folded portion to abut against shoulder and base portions of the bottles, applying glue to the exterior faces of the end flaps, and then folding inwardly the flaps which for the sake of convenience of description may be called "side flaps"
connected to the longer sides of the cross-section to press against the glue-bearing faces of the end flaps. A strong bond resulted between the side and end flaps because of the resistance to inward movement of the flaps offered by the bottles.
Attempts have been made to employ these cartons for packaging bottles which are taller and have a long tapering neck. In order to accommodate these bottles, cartons were used having end panels (i.e. the panels of shorter width) of approximately the same length as the earlier cartons, but having side panels which were somewhat heightened. When this carton was closed in the conventional procedure described above, one flap, adjacent the narrow neck of the bottle, was unsupported and flexed inwardly on application of pressure, resulting in a failure to form a secure `` `:
~ Z~
glued bond to the side Elaps which were folded onto it, because the unsupported end flap is not long enough to abut in supported relation against the shoulder or base portion of the bottle.
Attempts were made to solve this problem by using a carton with end flaps elongated sufficiently to engage against the shoulder or base portions of the long-necked bottles~ Although the carton solved the above-noted problem because the thusly-supported end flap did not flex inwardly, a substantial portion of the card-board or other packaging material was wasted because the usual procedure for forming the carton blank consists of severing the blanks from continuous lengths of packaging material. The end and side flaps are formed adjacent one side of the transverse severing line. Hence formation of longer end flaps resulted in longer side flaps, the side flaps thus comprising excess or redundant end portions which might be but were not necessarily cut off. In any event, the longer side flaps resulted in excessive wastage of the packaging material. This was very costly.
The present invention provides a method of packaging comprising providing a generally rectangular cross-section tubular car.on of stiff packaging material having at least one open end provided with a flap connected to each edge thereof, and containing an item or items offering resistance to inward movement of the flaps adjacent one zone of the open end and substantially no resistance to such inward movement adjacent an opposite zone, and wherein said flaps are folded inward and overlapping flaps are bonded to underlapping flaps to form a closed end, with the flap on the end edge adjacent the opposite zone being folded inwardly after the folding inwardly of the flaps on the side edges adjacent said end edge and being bonded to the exterior thereof. ~ith this method, the portions of the side flaps adjacent said one zone are supported by engagement with the portion or portions of the item or items that offer resistance to inward movement, and through their own stiffness support and offer resistance to inward movement of the end flap adjacent the said opposite zone, when ~, 37~
this is folded inwardly after the side flaps. This results in a good bond between the end flaps and the side flaps.
This method also allows the use o~ a carton blank with all flaps of the same length, and reduces the costs as compared with the known carton blank with elongated end flaps.
The present invention also provides a filled and assembled generally rectangular cross-section tubular carton of stiff packaging material containing an item or items offering adjacent at least one zone of one end of the carton resistance to endwise inward movement and substantially no resistance to such inward movement adjacent an opposite zone. The end is closed by flaps connected to the edges thereof and folded inward with overlapping flaps bonded to underlapping flaps, and having the flap on the edge adjacent the opposite zone overlapping and bonded to the exterior of the flaps on the side edges adjacent said edge.
A preferred embodiment of the present invention will now be described with reference to the drawings and detailed description which follow. These are directed not only to the aforesaid method of packaging and assembled carton which are the subject of the present application, but also to a printed carton biank adapted for use in the method.
The carton blank is the subject of a divisional application. In the drawings: ........................

Figure 1 is a partially fragmentary perspective view of a filled generally rectangular cross-section tubular carton;
Figure 2 is a fragmentary perspective view of the carton after closure of the side flaps and one end flap;
Figure 3 is a perspective view of the carton after closure of all flaps; and Figure 4 is a cross-sectional view taken on the line 4-4 in Fig.

Referring to the drawings, a printed carton blank 1 comprises four serially connected rectangular panels 2,3,4,5 of the same length. Connected to panel 5 is an edge flap 5a, bonded to panel 2 so tha~ the blank forms, when erected, a tubular elongated rectangular cross-section carton. Preferably, the edge flap 5a is bonded to flap 2 with glue. An end flap 9,10,11,12 is connected to each end of each panel 4,5 forming a shorter side of said cross-section and a side flap 19,20,21,22 is connected to each end of each panel 2,3 forming a longer side of said cross-section. One end flap 10,11 at each end bears printed matter 32 arranged so that the printed matter 32 appears continuous with the printed matter 33 borne on adjacent portions of the carton when the end flap 10,11 is folded on the outer side of the adjacent side flaps 19,20,21 and 22. For example, one side flap may bear a representation of a lower portion of a beer bottle which is completed by a representation of the upper portion of the neck of the bottle borne on the adjacent end flap.
In use, the blank is preferably employed for packaging an item or items 41 offering resistance to inward movement of the end flaps 9 and 12 adjacent one zone of each open end and substantially no resistance to such inward movement of the end flaps 10 and 11 adjacent an opposite zoneO Examples of such item or items 41 are long-necked beer bottles which have a wide diameter base and a long tapering neck. The length of the neck is sufficiently great that the end flaps 10,11 do nok contact the shoul~er of the bottles when folded inwardly.
In the packaging method, the bottles 41 are introduced into the executed carton blank as shown in Figure 1, though one or both ends, using conventional bottle handling machinery. ~efore closing the ends of the carton, a separator, for example a longitudinally eY.tending panel 13 shown in broken lines in Figure 1, may be introduced bet~een the bottles. In closing the ends, preferably the lower end flaps 9 and 12 are folded inwardly first. This arrangement produces a tray-like configuration, formed by the lower end flaps 9 and 12, the bottom panel 4 and the opposite side panels 2 and 3, which is considered to strengthen the finished packageO Glue is applied on the outer side of the flaps 9 and 12, and the side flaps 19,20,21 and 22 are folded and pressed inwardly to bond their lower portions to the outer sides of the end flaps 9 and 12. Preferably, the end and side flaps are each of the same length, approximately one-half of the width of the opening between the panels 2 and 3 to which the side flaps are attached. Thus, when folded inwardly, the side flaps 19 to 22 substantially close the end openings of the carton. The small space between the adjacent edges of the inwardly folded side flaps 20 and 21 is shown exaggerated in figures 2 and 3. Glue is applied on the upper portions of the side flaps 19,20,21 and 22, and the upper end flaps 10 and 11 are folded inward and bonded to the underlapping side flaps 19,20,21 and 22 as seen in Figure 3.
As best seen in Figure 4, the side flaps 20,21, through the underlying flap 9, engage against the base portion of the bottles 41 that offer resistance to inward movement of the flaps 9, 20 and 21. Thus, when pressure is applied to the upper end flap 10 to bond this to the side flaps 20 and 21 the latter, through their own stiffness, react with the flap 10 so that a good bond is achieved. Typically, the carton blank is made of corrugated cardboard, or like stiff packaging material.
~7~
The resulting filled and closed carton has at each en~ one end flap folded on the outer ~ace oE each side flap and one end flap folded underneath each side ~lap. In the preferred form, the carton blank bears printed matter on each lower end flap 9 and 12 arranged so that the printed matter appears continuous with printed matter borne on the remainder of the carton where the flap 9 or 12 is folded under the side flaps. For example, a central upper portion of the ~lap 9 may bear a printed representation of a pile of ice cubes which will appear continuous with representations of a pile of cubes continuing along the lower portions of the side flaps 20 and 21.
In the preferred form, the side and end flaps are generally rectangular with rounded corners. The lower end flaps 9 and 12 may be generally trapezoidal with the side edges thereof tapering slightly inwardly away from the line of attachment of the flap to the lower panel 4 The lower edges of each side flap may incline slightly inwardly away from its line of attachment to the side panels of the carton. The inclining edges of lower end flap and the side flaps then cooperate together in a camming action to assist in erecting the carton to its rectangular cross section tubular configuration from a flat-folded configuration.
Although in the above detailed description both ends of the carton are closed in the same manner, it will be appreciated that if allowed or required by the nature of the contents to be packaged therein, one end of the carton may be closed by the method described above in detail and the other end closed in a conventional manner.
It will be appreciated that, if the manufacturer of the carton blank is not the user thereof, the carton blank ma~ be supplied to the user with the panels 2 and 5 connected together along their longitudinal edgesr or disconnected, in which case a first step in the packaging method may be to bond the edge flap 5a to the panel 2.
~2~7~Sl Instead of employing glue to bond the portions of the blank and carton together other means of pressing and bondiny together may be employed, for example heat sealing methods in the event that the blank and carton are formed from or coated with heat-fusible material.

One end flap 10,11 at each end bears printed matter 32 arranged so that the printed matter 32 appears continuous with the printed matter 33 borne on adjacent portions of the carton when the end flap 10,11 is folded on the outer side of the adjacent side flaps 19,20,21 and 22.
