About half sized openings. When the perforated fold lines 44a and 48a overlap at least partially over the same space, the long apertures of the fold line 44a are oriented in one direction along the fold lines from the long apertures of the fold line 48a. It is biased. This maximizes the matching of the openings, thereby minimizing the matching of thick paper that is crimped or folded in the area of the connection between the top wall 18 and the end upper closure panel 34a. In this manner, three layers of materials 34a / 18, 38a / 42a, 40a / 46a can be folded to produce an edge of approximately 90 ° when the carton 30 is fully assembled. The carrying handle between the two gripping positions (ie, gripping openings 58a, 56a, 54a and finger gripping opening 74a) is thereby reinforced. The connection between the top panel 18 and the end top closure panel 34a is also reinforced while not obstructed by the overlapping three layers of material according to the other case without the fold lines 44a, 48a comprising the opening. Is strengthened. In order to be able to fold several layers of material, the used perforated fold lines having an off-set opening arrangement form a different aspect, different from the application to the carton carrying handle described herein. It may be applied to material folding.

Finally, the adhesive flap 12 is bonded to the inner surface of the first side panel 20 by an adhesive or other fastening means so that a flat tubular structure is produced. This is illustrated in FIG. 5, where both carrying handle structures are shown.

Once the tubular sleeve is fully filled, the ends are closed by assembling the composite end walls. The composite end walls fold each end upper closure panel 34a, 34b downward with respect to fold lines 70a, 70b; Each end bottom side closure panel 30a, 30b is folded upward with respect to fold lines 66a, 66b; And it is formed by fixing each end bottom side closure panel 30a, 30b to the outer surface of each end upper closure panel 34a, 34b. In carrying out this, a four-ply reinforcement carrying handle structure is formed in each compound end wall, and the outer gripping openings 60a, 60b are formed with the inner gripping openings 54a / 56a / 58a, 54b, 56b, 58b. Overlaps. The order of the folding process may be different in other embodiments. In other embodiments, the end bottom closure panels 30a, 30b may not include openings as such, and may have an edge similar in shape to one side of the gripping openings 54a, 56a, 58a. will be. The finished carton 30 is illustrated in perspective view in FIG. 6 and in cross section along the X-X line in FIG. 7.

A typical way of using the carrying handle structure is that a user pushes the three to four fingers into the gripping openings 60a / 58a / 56a / 54a by pushing the handle flap into the carton 30 and its edge. 8 is shown. The user's fingers / hands are cushioned by the handle flap 62a. The user also inserts the thumb into the finger gripping opening 74a by pressing the finger flap 78a into the carton 30 (see FIG. 9). By providing two gripping positions in adjacent walls, respectively corresponding to the composite end wall and the top wall, the carton 30 is gripped more easily than in the prior art handle arrangement in which only one gripping position is provided. By reinforcing the edges of the carton 30 between the two gripping positions, a strong arrangement that does not crush or break during normal use is formed, providing a sturdy and easy to use four-ply handle arrangement.

In other embodiments, the gripping location provided on the top wall 18 is sized to receive more of the user's hand than a single finger. In a further embodiment, the gripping location provided on the composite end wall is sized to accommodate a smaller portion of the user's hand than three or four fingers. In a further embodiment, the top panel 18 is reinforced in the region of the finger grip opening 74a. In some embodiments, this reinforcement is provided by fixed panels 42a and 46a. The use of the finger grip opening 74a is optional.

When folded, they are arranged to overlap with the first gripping openings 350a and 350b. Therefore, the direction of the second gripping opening is determined at a similar acute angle α with respect to the fold lines 358a and 358b. The geometry of the second gripping opening is illustrated in FIG. 11, in which the angle α between the fold line 358a and the fold line 334a is shown. Similar angles α between the upper edges 360a and 360b and the fold lines 358a and 358b are also shown. (For convenience of explanation, the imaginary line 370 is drawn as an extension of the upper edges 360a and 360b of the second gripping openings 352a and 352b. The imaginary line 370 is a second gripping opening portion ( In order to clearly express the angle α between 352a and fold line 358a, it is added to blank 310 but does not itself form part of the blank.)

The assembly of the carrying handle of the third embodiment of the present invention will now be described with reference to only the left side of the blank 310 in detail, while a similar carrying handle is understood to be provided on the right side of the blank 310. Preferably, the blank 310 is provided to the processing plant in a partially assembled form in which the carrying handle structure is at least partially formed and the first side panel 312 is secured to the bottom panel 318 by an adhesive flap 320. Will be provided. The resulting flat shaped tubular sleeve 390 is shown in FIG. 15.

Assembly steps of the partially assembled carton sleeve 390 are illustrated in FIGS. 13 and 14. Preferably, these steps are performed in a straight line packaging machine to alleviate the need for the blank 310 to be rotated during assembly. As shown in FIG. 13, adhesives G1, G2, G3, G4, G5, G6, G7 are applied to the end upper closure panel 324b. Preferably, the adhesive and / or other adhesive and / or fixing means are applied in a linear arrangement, substantially perpendicular to the fold line 334b and substantially parallel to the direction of travel X of the blank 310. In another embodiment of the present invention, suitable fastening means other than the adhesive is used to ensure that the firm fastening of the end upper closure panel 324b affects the reinforcing panel 354b. Non-limiting examples of such suitable fasteners include mechanical fixings such as staples, pressure or thermally active adhesives and sticky tapes.

In other embodiments, the adhesive or adhesive material may take a variety of configurations, such as, for example, only adhesive strips G1, G5 and G3 are provided in one expected embodiment.

However, while folding the reinforcement panel 354b against the fold line 358b, to mitigate or remove any spilling or dripping of adhesive on the packaging machine and / or carton blank 310, It is advantageous to apply to the end upper closure panel.

In the described embodiment, the left 'b' side of the blank 310 (as shown in FIG. 11) provides a leading edge of the carton blank 310 as it moves through the carton forming machine. As the blank 310 is symmetrical, it will be appreciated that the right 'a' side of the blank 310 may instead provide a front edge.

By transferring the blank 310 in the 'X' direction through the processing line, a single gluing apparatus of the machine is first applied to the front end upper closure panel 324b and subsequently to the rear end upper closure panel. 324a may be used to apply the adhesives G1, G2, G3, G4, G5, G6 as described above. In this way, the adhesive applicator and folding apparatus, which are required to perform the adhesive application and folding operations necessary for assembling a partially formed tubular carton sleeve 390 (see FIG. 15), are simplified.

A further step in the assembly of the partially formed tubular carton sleeve 390 in flat form is illustrated in FIG. 14. The bottom panel 318 is folded about the fold line 346 and overlaps in surface contact with the second side panel 316 and a portion of the top panel 314. An additional adhesive application operation is carried out and an adhesive bead or adhesive strip G7 is applied to the outer surface of the adhesive flap 320. In other embodiments, other adhesives or fastening means may be used. Additionally or alternatively, the adhesive strip G7 may be an interrupted strip. The first side panel 312 is then folded about the fold line 342 such that the first side panel 312 is folded in surface contact with the portion of the top panel 314 and the adhesive flap 320. The panel 318 and the first side panel 312 may be fixed to each other, a tubular structure with an open end may be formed, and the once formed carton sleeve 390 is left open.

The partially assembled flat shaped carton sleeve 390 will be supplied to the processing plant in a flat form. At the processing plant, continuous flat shaped carton sleeves 390 will be supplied to the packaging line. There, the partially formed flat shaped carton sleeves 390 are opened in a tubular structure and are filled with articles at one or both ends. In this embodiment, the articles are bottles B as shown in FIG. 16. In alternative embodiments, articles of various types, shapes, and sizes are used, such as, for example, other primary packaging containers, such as cans (in embodiments where the shape of article B does not gradually narrow, the first And instead of the second side panels 312 and 316 becoming narrower, their edges will be shaped to conform to the shape of other types of articles to be housed inside the carton 330). In order to restrain the articles B inside the carton 33, each end of the carton 330 is tightly closed. In this embodiment, the end top closure panel 324a, the end side closure panels 322a and 326a and the end bottom closure panel 328a are folded and secured in a general manner (as shown in FIG. 17). In another embodiment, the end top closure panel 324a, the end side closure panels 322a and 326a, and the end bottom closure panel 328a indicate that the articles B are held securely inside the carton 330. Although closed enough to ensure, it may be sized and shaped to only partially close the ends of the carton 330.

The finished carton structure 330 is shown in FIG. 18. At this time, the two-ply reinforcement carrying handle structure (350a / 352a, 350b / 352b) can be utilized by the user to carry the filled carton 330.

For example, various changes may be made within the spirit of the present invention, such that the size and shape of the panels may be adjusted to accommodate articles of different size and / or shape and / or number and / or arrangement. You will realize that In another embodiment of the present invention, it is contemplated that the size and / or shape of the gripping opening may be adjusted to accommodate a smaller or larger portion of the user's hand. In further embodiments, it is envisaged that the gripping openings may be initially covered by a dust flap, which is movable to expose the gripping openings or gripping openings to protect the article inside the carton. In other embodiments, it is also contemplated that two handle reinforcement panels may be provided, hinged to adjacent end upper closure panels, respectively, along inclined fold lines 358a, 358b. It is also contemplated that various components of the illustrated embodiment may be used with components of other embodiments. For example, the carrying handle of FIGS. 11-18 additionally includes, in another embodiment, the finger grip openings of the first two embodiments. As used herein, "top", "bottom", "front", "rear", "end", "side", "inner", "outer", It will be appreciated that directional references such as "upper" and "lower" do not limit individual panels in that direction, but merely serve to distinguish these panels from each other.

Any reference to a hinged connection or crease must not be construed as referring to a single crease; Indeed, the hinge connection or fold line may be one or more of the following short slit, frangible lines or interrupted fold lines without departing from the spirit of the invention. It is expected that it can be formed.
