Definitions

• the present invention relates generally to an enclosed paperboard carton capable of enclosing cylindrical containers which has a unique opening and dispensing feature that allows the containers, for example cans, to be removed or dispensed while preserving the overall structural integrity of the carton.
• This dispenser can be used on a carton containing cans or other types of cylindrical containers arranged in three rows. This dispenser prevents the containers in the first two rows from rolling out when opened, but provides for the easy removal of all containers in the carton, including the containers in the bottom row.
• the size of the dispenser opening of this invention has been greatly reduced to preserve the structural integrity of the carton during handling and also after the dispenser has been opened.
• the dispensing feature may also provide a safety net for the first container that is dispensed when the carton is opened.
• This carton is generally rectangular and has a bottom, a top, two sides, a closed end and an exiting end.
• the carton is foldably constructed from a blank having panels and flaps.
• the exiting end, or ends, of the carton permits containers to be taken from the carton via the dispenser.
• This carton has a dispenser that is formed from a dispenser flap that is attached to tire carton by a bottom tear line in the exiting end that is generally parallel to the bottom that extends only partially across the exiting end of the carton, with side tear lines extending from the bottom tear line to form an end retainer in the exiting end of the carton adjacent each side panel.
• Each side tear line turns into the adjacent side panel and extends diagonally through the side panel and extends into the top panel where the tear lines meet to form a top tear line.
• the bottom tear line is based at least a sufficient distance from the bottom panel to restrain the containers in the bottom row from rolling out while the end retainers extend into the exiting end of the carton at least a sufficient distance from each side panel and from the bottom panel to prevent the containers in the middle row from rolling out when the dispenser is opened.
• the distance from the top tear line to the fold line between the top panel and top end panel is significantly less than the diameter of a container to be contained in the carton.
• this distance is between 70 and 85% of the diameter of a container to be contained in the carton.
• the distance can be as short as one half the diameter of a can plus approximately three millimeters.
• the bottom tear line is preferably located at a distance from the bottom panel that is between one-third and two-thirds of the diameter of a container in the bottom row.
• the ends of this carton are preferable closed by a bottom end flap, two side end flaps and a top end flap that are glued together.
• This carton is ideally suited for carrying twelve cans in three rows with four cans in each row, but can be designed to carry more cans or cylindrical containers.
• this carton is constructed with a bottom end flap having a height somewhat less than the diameter of the can in the bottom row with a bottom tear line, being located immediately adjacent to the end of the bottom end flap for ease of tearing off or folding the dispenser flap.
• a dispenser opening flap is attached by a fold line in the top panel to the dispenser flap to aid in commencing the opening of the dispenser flap.
• This carton may have a carrying handle in the top panel.
• the end retainers are preferably constructed so that they only extend along a portion on each end of the can in the second row to prevent it from rolling out of the carton, but to permit its easy removal from the carton.
• the bottom tear line in the exiting end of the carton is placed close enough to the bottom to permit the easy removal of cans in the bottom row.
• each side tear line that extends from the bottom tear line in the exiting end of the carton can be curved near its top towards the adjacent side panel so that only a small portion of the end retainers prevent the can in the second row from rolling out of the carton.
• the end retainers only need extend upwardly a short distance above the can in the bottom row to prevent the can in the second row from automatically rolling out.
• the end retainers need not extend upwardly more than one eighth or one fourth of the diameter of the can in the second row. Utilizing this feature permits the easy removal of cans from the carton, but prevents them from automatically falling out.
• the bottom line in the end of the carton as a fold line rather than a tear line, a basket is formed when the dispenser flap is opened to catch the first container that automatically falls out of the carton.
• this carton is constructed with a bottom end flap having a height somewhat less than the diameter of the can in the bottom row with a bottom fold line or tear line, depending on which is used, being located immediately adjacent to the end of the bottom end flap for ease of tearing off or folding the dispenser flap.
• This carton can be constructed by gluing, taping, stapling and the like, or by locking.

Placing the bottom tear line 168 at the minimum distance BH from the bottom permits easy access to remove cans from the bottom row of the carton , as illustrated by CI in FIG. 7, by reaching in through the dispenser 184 and removing the cans. The middle row of cans, as illustrated by C2 in FIG.
• end retainers 164 and 166 which are formed by not extending bottom tear line 168 all the way across the dispensing end 180 of the carton.
• Tear line 162 extends upwardly from each end of bottom tear line 168 and forms end retainers 164 and 166.
• These end retainers 164 and 166 extend into the dispensing end 180 of the carton at least a sufficient distance W from side panels 114 and 122 and at least at a sufficient height EH from the bottom of the carton to prevent the cans (C2) in the middle row from rolling out of the open dispenser while the bottom of the carton is in a horizontal plane.
• the width W of end retainers 164 and 166 as shown in FIG s.
• bottom tear line 168 can be spaced from the bottom of the carton at a distance BH greater than the minimum height necessary to restrain cans CI in the bottom row from automatically rolling out of the open dispenser 184.
• end retainers 164 and 166 can have a greater width W and height EH than the minimum required to prevent cans C2 in the second row from rolling out of the open dispenser 184.
• tear line 162 turns at an angle in its location adjacent a side panel 114 or 122 in its upper portion in the dispensing end 180 of the carton towards the adjacent side panel 114 and 122 so that only a small portion of end retainers 164 and 166 prevent the can C2 from rolling out of the carton as illustrated in FIG. 7.
• the end retainers 164 and 166 only need to extend upwardly a short distance above the can CI in the bottom row as illustrated in FIG. 7 to prevent the can C2 in the second row from rolling out.
• end retainers 164 and 166 need not extend upwardly from the bottom panel more than one-eighth or one-fourth of the diameter of the can C2 in the second row.
• the height BH be approximately the same or slightly more than the distance from fold line 132 to end 184 (FIG. 5) of bottom end flap 130 and to end 186 of bottom end flap
• T in a carton carrying these twelve ounce cans could be as short as 36 millimeters. It is preferred that this distance be between 70 and 85% of the diameter of a container. In the case of the twelve ounce can, a distance of 53 millimeters is preferred.
• T can be as short as one half the diameter of a container, such as a can, plus approximately three millimeters applies to other can sizes within the standard range of sizes of beverage cans packaged in cartons. This fonnula has been tested and determined to be applicable to cans of smaller and greater diameters. Greatly reducing the distance
• T improves the ability to fold the various flaps on the dispensing end 180 of the carton. This is important because these flaps are folded and glued at high speed in a packaging machine. Greatly reducing the distance T obviously results in the carton having a smaller dispenser flap 170. Reducing the size of the dispenser flap 170 reduces the likelihood of the tear lines 162 and 168 being torn during shipping and handling by a consumer.
• the dispenser 184 is open on a carton where the distance T has been greatly reduced, the void of the dispenser 184 in the carton is greatly reduced, which means that more structure of the carton remains which enhances the structural integrity of the carton after the dispenser flap 170 has been removed.
• the distance T between the dispensing end 180 of the carton is measured from fold line 132 to where tear line 162 intersects fold line 120.
• the distance T on side panel 122 between the intersection of tear line 162 and fold line 124 and the dispenser end 180 is the same as it is in side panel 114 as described.
• This dispenser flap 170 is easy to open because top tear line 174, which is an extension of tear line 162A, provides easy access for a person's fingers to be inserted. It has been found that providing cuts in score line 178 and nicks in fold line 176 makes it easy to use a dispenser opening flap 172 to open the dispenser flap 170. The actual pulling open of the dispenser flap 170 along fold line 176 enables the dispenser flap 170 to be easily pulled opened even though distance T is short.
• FIG. 8 illustrates another embodiment of this invention.
• FIG. 8 is a plan view of a blank which is identical to the blank shown in FIG. 5 except for having a different dispenser opening flap. This blank 210 can be formed in a carton in the same manner as the blank illustrated in FIG.
• the blank 210 illustrated in FIG. 8 has a different type of dispenser opening flap 211 than the dispenser opening flap 172 illustrated in FIG. 5.
• the tear line 212 shown in FIG. 4 is similar to tear line 162 illustrated in FIG. 5 except in the top panel 118.
• the dispenser opening flap 170 illustrated in FIG. 8 has a tear line 212. This tear line 212 meets nicked cut line 216 in dispenser opening flap
• This dispenser opening flap 211 has a curved score line 214 that extends across top panel 118 and meets tear line 212 at the side of top panel 118 near side panel 114, and on the other side of the top panel 118 near side panel 122.
• Cushioning flap 219 is formed between curved score line 214 and nicked cut line 216.
• Triangular score line 218 may be formed in top panel 118 as an extension to tear line
• Triangular score line 218 preferably meets curved score line 214 where the latter meets tear line 212 near side panel 114 and also near side panel 122.
• a small longitudinal cut line 220 may be formed to facilitate the entry of a person's fingers into dispenser opening flap
• the distance T' from fold line 132 to nicked cut line 216 at fold line 120 in top panel 118 can be as short as one half the diameter of a can plus approximately three millimeters. Preferably this distance is between 70 and 85% of a diameter of a container to be contained in the carton.
• T' can be basically the same distance as T in FIGs. 5-7. This short distance T' is made possible by the features of the carton described above in connection with FIGs. 5-7.
• the construction of the dispenser opening flap 211 facilitates reducing the distance T'.
• This dispenser opening flap 211 is engaged by a person inserting his or her fingers between triangular score line 218 and nicked cut line 216 with the fingers folding cushioning flap 219 and engaging curved score line 214 which is pulled forward opening the dispenser flap 170.
• bottom tear line 168 can be constructed as a fold line which will allow dispenser flap 170 to be utilized as a basket or safety net for catching cans dispensed from the carton.
• the dispenser of this embodiment of the invention provides an easy opening feature in that it has a dispenser opening flap where a person's fingers can be inserted to open the dispenser flap.
• dispenser embodiments of this invention can be used with cartons containing two rows of cans with a plurality of cans in each row. Cartons with three or more rows of cans can also utilize the dispensers of this invention. While the invention has been disclosed in its preferred forms, it will be apparent to those skilled in the art that many modifications, additions, and deletions can be made therein without departing from the spirit and scope of the invention and its equivalents as set forth in the following claims.
