Description

TITLE: CUTTING BRICK FOLDING CARTON AND BLANK
DESCRIPTION
The present invention relates generally to folding paperboard cartons, and more particularly to an improved carton blank for use in assembling a carton having improved accessibility, recloseability and appearance.
Folding cartons are well known in the packaging art. These cartons are constructed from flat blanks which are pre-cut and pre-scored on paperboard sheets. Carton blanks have four main panels which are adapted to form the top, rear, bottom and front of an assembled carton. Each panel has a pair of and flaps which are hingedly connected by score lines formed in the paperboard.
The blanks are folded once and secured with known adhesives to form carton sleeves which are used for packaging retail products, typically consumable goods. During the filling operation, packaging machinery is used to form and seal fully assembled cartons according to a prescribed folding sequence and adhesive pattern.
U.S. Patent No. 5,288,012 describes a state-of- the-art carton blank used to assemble a rectangular, top opening carton. First and second ends of the carton are closed by folding the bottom panel and flaps first; front panel end flaps second; top panel end flaps third and rear panel end flaps fourth and last.
Prior to folding in the fourth down flap, single lines of adhesive are deposited on the bottom panel end flaps. All four end flaps are secured by single glue lines to form a smooth, continuous wall at first and second ends of the carton.
Carton blanks are typically produced on large paperboard sheets in a multiple configuration. Individual blanks are internally "nested" on three sides to minimize the amount of excess or wasted paperboard. During the blanking operation, score lines are provided to facilitate the flap-folding sequence. Perforations are also cut in the paperboard to form art-recognized tear-away and breakaway features like those described in U.S. Patent No. 4,712,689. Perforations and score lines are formed by die-cutting and die-stamping the carton blanks in a single, downward direction. Accordingly, it is a general object of the present invention to provide improvements in a carton for packaging materials.
It is another object of the present invention to provide a carton blank which has improved accessibility through use of perforations cut in the paperboard to form multiple tear-away features formed by a simple blanking operation.
Another object of the invention is to provide a carton blank which has improved recloseability through use of perforations cut in the paperboard to form multiple tear-away strips and pockets, formed by a simple blanking operation.
It is yet another object of the present invention to provide a carton blank for forming a carton having a low profile. According to one aspect of the present invention, a blank for forming a carton is provided. The blank includes front, bottom, rear and top panels which are hingedly connected by score lines and adapted to form a corresponding sleeve which is readily converted into an open-ended carton, closed at one end, filled with a selected product and closed at the other end in a manner well-known in the art.
Each main panel has first and second flaps which are hingedly connected at bottom and top ends. Score lines are disposed between the main panels and their respective end flaps. Optional lips or membranes are hingedly connected to the top edge of the front panel and flaps of the carton blank. Releasable tear strips are formed in the top panel and flaps by perforations in the paperboard stock.
The blank also includes a cover panel portion hingedly connected to the top panel and adapted to overlap the front panel. In one embodiment, a releasable tear strip may also be formed on the cover panel portion by perforations in the paperboard stock. The cover panel preferably has at least at one end an end tab which in forming a carton is interposable between top and bottom end flaps of the blank. The tabs are preferably adhered to the interior surface of the top end flap. As an important aspect of the present invention, score lines and perforations are formed by die-cutting or die-stamping the carton blanks in a single, downward, uniform direction.
Reference is now made to the following detailed description of the preferred embodiments in connection with the accompanying drawings. Additional disclosure is provided by U.S. Patent Nos. 5,288,012, 5,351,881 and 5,409,160, which are all incorporated by reference in this specification. Figure 1 is a perspective view of a flat carton formed in accordance with one embodiment of the present invention and shows the low profile, aesthetically pleasing appearance in the form of a "cutting brick";
Figure 2 is a perspective view of a flat carton formed in accordance with another embodiment of the present invention; Figure 3 is a plan view of a flat carton blank formed in accordance with one embodiment of the present invention;
Figure 4 is a plan view of a flat carton blank formed in accordance with the embodiment shown in Figure 2;
Figures 5A and 5B are fragmentary, perspective views of one end of the carton during the folding sequence; Figure 6 is a plan view of a flat carton blank formed in accordance with another embodiment of the invention; and
Figures 7A and 7B are fragmentary, perspective views of one end of the carton being formed from the blank of Figure 6 during the folding sequence.
Referring to the embodiment of the invention illustrated in Figure 1, a flat carton generally designated A is shown with top panel 5, cover panel 4 and front panel 8. One end of carton A is shown generally in the drawings with top panel 5 continuous with end flap 5A on which is shown tear-away strip 5C. Strip 5C is defined by upper and lower die-cuts or perforations 13 and 14. Also shown on end flap 5A is lip portion 19. Similarly, Figure 2 depicts a flat carton generally designated B shown with top panel 5 continuous with end flap 5A on which is formed tear-away strip 5C defined by upper and lower perforations 13 and 14. Additionally, cover panel 4 is depicted as having tear- away strip 4A defined by upper and lower perforations 113 and 114.
Referring to Figure 3, a carton blank is shown designated A and comprises cover panel 4, top panel 5, rear panel 6, bottom panel 7 and front panel 8 hingedly connected in the order named. More specifically, cover panel 4 and top panel 5 are hingedly connected by score line 9; top panel 5 and rear panel 6 are hingedly connected by score line 10; rear panel 6 and bottom panel 7 are hingedly connected by line 11 and bottom panel 7 and front panel 8 are hingedly connected by score line 12. Each score line is formed in the downward direction with reference to the upper surface of blank A. Along with other aspects of the present invention, score lines 9-12 permit simple manipulation of blank A to form an assembled carton for universal packaging of pre-selected products.
As shown generally in the drawings, top panel 5 includes first and second end flaps 5A and 5B on which are formed tear-away strips 5C and 5D, respectively. Strip 5C is defined by upper and lower die-cuts or perforations 13 and 14, while strip 5D is defined by perforations 131 and 141. Lip portions 19 and 19A are also shown on end flaps 5A and 5B. Bottom panel 7 includes first and second end flaps 7A and 7B on which are cut pockets 119 and 119A, respectively.
In the assembled carton, lip portions 19 and 19A on top panel end flaps 5A and 5B can engage pockets 119 and 119A on bottom panel and flaps 7A and 7B, respectively. This feature allow recloseability of either or both end flaps 5A and 5B after either strips 5C and/or 5D have been removed. Pockets 119 and 119A on bottom panel end flaps 7A and 7B are cut in the same blanking operation as with the formation of score lines 9-12, and along with die-cuts 13, 131, 14 and 141, are all formed in a downward direction with reference to the upper surface of blank A. Main panels 4-8 have first and second end flaps hingedly connected by adjacent fold lines. Specifically, first and second bottom panel end flaps 7A and 7B are hingedly connected to bottom panel 7 by intermediate fold lines 15A and 15B, respectively. In like terms, first and second front panel end flaps 8A and 8B are hingedly connected to front panel 8 by intermediate fold lines 16A and 16B; first and second top panel end flaps 5A and 5B are hingedly connected to top panel 5 by intermediate fold lines 17A and 17B; and first and second rear panel end flaps 6A and 6B are hingedly connected to rear panel 6 by intermediate fold lines 18A and 18B.
Figure 4 depicts a carton blank generally designated B and is shown having cover panel 4 on which is formed tear-away strip 4A defined by upper and lower perforations or die-cuts 113 and 114. Cover panel 4 is hingedly connected to top panel 5 via score line 9. Die-cuts 113 and 114, and score line 9 are cut/scored in the same blanking operation in a downward direction with reference to the upper surface of blank B. As shown in greater detail by Figures 5A and 5B, carton blank A is partially assembled by arranging rear panel end flap 6B, front panel end flap 5B, bottom panel end flap 7B and top panel end flap 5B according to the following flap folding sequence. Rear panel end flap 6B is first folded along score line 18B; front panel end flap 8B is next folded along score line 16B (as shown in Figure 5B) and bottom panel end flap 7B is then folded along score line 15B to contact rear panel end flap 6B and front panel end flap 8B. Tear-away strip 5D is next releasably secured to bottom panel end flap 7B by adhesives along end flap 5B.
Additional features of the present invention will now be described. Using blank B, a carton is assembled by first forming an intermediate carton sleeve. Cover panel 4 of blank A is folded along score line 9 to overlie a portion of front panel 8. Glue is then applied to the interior side of cover panel 4 or the exterior side of front panel 8 with care being taken to avoid the interior side of tear strip 4A. Cover panel 4 is applied to front panel 8 to form a carton sleeve. A carton is formed from this partially assembled sleeve. First, the sleeve is squared-up to form an open-ended carton. To accomplish this, the rear panel end flap 6A is first folded along score line 18A; front panel end flap 8A is next folded along score line 16A and bottom panel end flap 7A is then folded along score line 15A to engage rear panel end flap 6A and front panel end flap 8A. Glue is then applied to the interior side of top panel end flap 5A or the exterior side of bottom panel and flap 7A with care being taken to avoid the interior side of tear strip 5C. Top panel end flap 5A is applied to bottom panel end flap 7A forming the open-ended carton.
During a typical filling operation, preselected solid or semi-solid products such as candy, ice-cream, snack chips, novelty items and the like are delivered to the receptacle formed by the open-ended carton. After appropriate filling, the carton is finally assembled by folding rear panel end flap 6B first along score line 18B; front panel end flap 8B is next folded along score line 16B and bottom panel end flap 7B is then folded along score line 15B to contact rear panel end flap 6B and front panel end flap 8B. Tear-away strip 5D is next releasably secured to bottom panel and flap 7B by adhesives along end flap 5B.
Finally, Figures 6 and 7A and B of the accompanying drawings show another blank/carton embodiment of the invention, which is in most respects the same as that shown in Figures 3 to 5. Like parts have been given the same reference numeral for ease of reference and will not be described again in detail. The main difference between the aforementioned embodiments is that the blank of Figure 6 has two tabs
20 one at each end of the cover panel 4. Score lines 22 between the tabs and the cover panel enable the tabs to be folded relative to the cover panel. The tabs 20 extend from the level with score line 9 between the cover panel 4 and top panel 5 to a minor extent relative to the height of the cover panel.
In assembling a carton from the blank of Figure 6, there is an additional folding step compared to the previous embodiment. As previously, the carton is formed in to a sleeve and the flaps at one end folded up and adhered except that after flap 7A has been folded up along score line 15A to engage rear panel end flap 6A and front panel end flap 8A, the tab 20 iε folded in. Glue is then applied to the interior side of top panel end flap 5A or the exterior side of bottom panel end flap 7A including the outer surface of tab 20 but not beneath tab 20 with care being taken to avoid the interior of tear strip 5C. Top panel end 5A is applied to bottom panel end flap 7A and tab 20 forming the open- ended carton so that tab 20 is only adhered to the inside surface of top panel end flap 5A, so as not to interfere with opening of the carton.
Once the carton has been filled, the other end of the carton is treated in the same way. The provision of the tabs 20 helps recloseability of the carton lid and, in the case of cartons containing ice-cream, reduces likelihood of ice crystals being built up on the ice cream due to contact with the air whilst in a freezer after being opened.
