Abstract

A beverage carton (10) has a center panel (20), a left panel (12) foldably connected to the center panel along a left fold line (32), a right panel (14) foldably connected to the center panel along a right fold line (34), and a strap handle (24) formed from the center, left and right panels. The strap handle extends transversely, instead of longitudinally, across the center panel between the left and right panels to absorb lifting forces in the side panels rather than end panels (13/16, 15/18) of the carton.

Description

  The present invention relates generally to product cartons, and more particularly to cartons having strap handles.

  Product cartons such as cartons used to contain bottles and cans for beverages and dietary supplements often have grip holes and strap handles to make the cartons easy to carry Is done.

When a carton and its contents are lifted using a strap handle, the weight of the package may cause the handle and some panel area for mounting the handle (generally depending on the orientation of the top wall panel), or , Will concentrate on other parts of the carton. Stress is generated by the concentration of weight, and this stress can cause deformation and destruction of the handle and various carton panels (particularly the top wall panel). Problems such as deformation, fracture and other tears can sometimes be solved by using multiple layers of materials as carton materials and / or by using thicker materials, but such Means increase the cost of the carton. It is not easily tearable, does not require the reinforcement of carton panels or the use of thick materials, nor reduces the structural strength of the carton while maintaining the quality of the carton material used. It will be appreciated that such a strap handle is desirable. To the best of the knowledge of the present applicant, there is no prior art document relevant to the present application. The present invention is directed to overcoming one or more of the problems set forth above.

One aspect of the present invention is a carton for a beverage container comprising: a central panel; a left panel foldably connected to the central panel along a folding line; A right side panel foldably connected to the central panel; and a strap handle provided by an integral part of the central panel, wherein the strap handle is at one or each end of the strap handle. Via a plurality of web panels located in the vicinity of the section, and via a cutting line extending from each web panel of the central panel into the adjacent side wall panel, bendably connected to the central panel, In such a configuration, the web panel can be bent upward from the surface formed by the central panel, and at the same time, the cutting line of the adjacent side wall panel and the central panel can be cut. The portion located between the straps can be displaced inward with respect to the carton, and by this displacement and the upward bending of the web panel, the strap handle itself is lifted above the plane formed by the central panel. Thereby providing a carton characterized in that the load is transferred into the side wall panel and distributed across the side wall panel.
In one aspect of this aspect of the invention, of the plurality of cutting lines extending from the central panel into the adjacent side wall panel, the cutting lines adjacent to each other are separated from each other in the adjacent side wall panel. They can be connected by folding lines extending across.
Preferably, the connecting folding line is arranged in the vicinity of the folding line connecting the center panel and one of the left panel and the right panel.
In another aspect of this aspect of the invention, the connecting folding line is directed from the end of the cutting line toward the vicinity of the folding line connecting the center panel and one of the left and right panels. Can be extended inward.
In a further feature of this aspect of the invention, the connecting fold line may have a portion that matches the fold line connecting the center panel and one of the left and right panels.
In yet another aspect of this aspect of the invention, the strap handle is disposed at each handle strap end adjacent to a pair of gripping holes that cooperate to form at least a portion of the handle strap. The pair of web panels thus made can be connected to the central panel so that they can be bent.

Another aspect of the present invention provides a blank formed from a single sheet material for forming the carton described above.
In other embodiments, strap handles are formed on the top and side wall panels and extend laterally across the top wall panel between the side wall panels. The handle is integrally formed with the side wall panels and is connected to the top wall panel using a plurality of web panels. By extending the web panel, the handle is separated from the top wall panel and can be easily gripped. Due to the size and placement of the handle and because the score line is located at the connection between the handle and the side wall panels, the load is directly from the handle to the side wall panels. Disperse and distribute throughout the sidewall panel.

In other embodiments , the strap handle is formed in the sidewall panel, the top wall panel, and the bottom wall panel and extends laterally across the sidewall panel between the top wall panel and the bottom wall panel. . The handle lifts the carton with the side wall panel facing up. The load is transmitted from the handle to the top and bottom wall panels connected to the handle.

The strap handle is also effective in cartons for bottles with long necks. In such a case, the handles are formed on the side wall panel and the top wall panel. The carton lifts each bottle horizontally, not each bottle vertically.

Several embodiments of the present invention are illustrated below with reference to the accompanying drawings.

  Note that throughout this specification and throughout the claims, designations such as “top wall” panel and “side wall” panel are for convenience of explanation and illustration. The use of these terms is not intended to add limitations on these panels.

As shown in FIGS. 1 and 2, the carton (10) includes a side wall panel (12, 14), an end wall panel (13, 15, 16, 18), a top wall panel (20), and a bottom wall panel. (22). The carton (10) is provided with a strap handle (24) that is transverse to the longitudinal direction. The lateral handle (24) can be used with the fingers extending between the end wall panels (13/16, 15/18) instead of extending the fingers between the side walls (12, 14). It is oriented so that it can grip the lateral handle. As shown, the carton (10) contains twelve beverage containers (A), and in this example forms a twelve pack. In this embodiment, cans and other articles packaged in a carton are placed with their respective longitudinal axes parallel to the lateral orientation made by the handle. When lifted by the lateral strap handle (24), the lifting force by the handle (24) is such that the top wall panel (20) and end wall panels (13/16, 15/18) or toward the side wall panels (12, 14) rather than toward the carton corner. Therefore, this lifting force is distributed over a wide area, and can be adapted to the load without increasing the thickness of the material forming the carton, thereby preventing the occurrence of tearing. By providing a plurality of intentional cutting lines and folding lines, the handle (24) can be lifted enough to allow the user to insert the hand, and the handle (24) can be gripped by the hand. Can carry a carton.

FIG. 2 shows a blank (26) that can form a carton (10). The blank (26) is preferably made of a single material and is divided into an end wall panel and a central panel by providing folding lines (28, 30). Top panels (20) is provided with a central top wall panel portion (20), and the end wall portion. Similarly, side wall panels (12, 14) includes a center panel portion, and the end wall portion (13,15,16,18), the. The top wall panel (20) is foldably connected to the side wall panel (12) along the folding line (32) and is also connected to the side wall panel (14) along the folding line (34). It is connected so that it can be bent. The side wall panel (14) is foldably connected to the bottom wall panel (22a) along the folding line (36). The bottom wall panel (22b) is foldably connected to the side wall panel (12) along the folding line (38).

In the blank (26), cuts are formed in the side wall panels and the related end wall panels, and break lines (cut lines with interruption points) (40, 42) are formed. Break lines (40, 42) allow material to be removed from these panels and form an outlet for the can. The bottom wall panel (22) has a plurality of score lines, thereby forming small triangular panels (44, 46). These triangular panels (44, 46) change the shape of the corner portion by bending, and avoid the corner portion from becoming a right angle. This bending causes the corner portion of the panel (14) to be rounded. The bottom wall panel (22) can also have score lines to form removable panels (48, 50).

  Panel (14) has rounded (rounded) corners, resulting in an octagonal shape. In each corner portion of the panel (14), a notch is formed in the blank. However, the end wall portion of the panel (14) is connected to the panel (20, 22) along a folding line and is connected to the end wall panel (16, 18) of the panel (14) by a score line (32). It connects with the adjacent end wall part of a panel (20, 22) by via the web connected with respect to. Thereby, at the time of the assembly of a carton, each end wall panel can be bent skillfully. The octagonal panel is aesthetically pleasing compared to the square cornered panel, and can therefore be used as a display panel (display panel). Octagonal corners also provide some flexibility for storage spaces that are not always square.

The lateral handle strap (24) has a main strap portion formed between two notches in the top wall panel (20). The handle flaps (52, 54) are connected to the handle (24) along the score line, and in the assembled state of the carton, the strap thickness is increased to increase the comfort of the grip holes. be able to. The entire handle assembly extends across the top wall panel (20) and onto the side wall panels (12, 14). Thereby, the handle assembly extends across the folding lines (32, 34). The handle assembly terminates in the sidewall panel (12) along the fold line (56). The folding line (56) has a central region and both ends that are angled toward the panel (12). For this reason, the folding line (56) has a concave shape, that is, an inverted “C” shape. Both ends of the inverted “C” shape terminate at or near the cutting line (58, 60) positioned above and below. The cutting line (58) extends downward and obliquely toward the folding line (32), and then extends horizontally on the panel (20). Similarly, the cutting line (60) extends upward and obliquely across the panel (12) toward the folding line (32) and then extends horizontally on the panel (20). is doing. The ends of the cutting lines (58, 60) are preferably J-shaped to prevent tearing and so that lifting forces can be guided into the bulk of the panels (20, 22). These J-shaped backs face each other. Therefore, these J-shaped curved portions extend in directions away from each other in the panel (12). Any shape other than the J shape can be used as long as it is curved away from the stress region to prevent tearing and disperse the pulling force into the bulk of the panel. Preferably, the cutting line (58, 60) is not a complete cutting line, but is jagged so that it can be easily separated after the carton is three-dimensionalized.

  The web panel (62) exists between the upper grip hole notch in the panel (20) and the horizontal portion of the cutting line (58) in the panel (20). The web panel (62) is defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the folding line, the main handle portion (24) can be lifted above the plane formed by the panel (20). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle (24), the second web panel (64) is foldably connected so that it can operate in cooperation with the web panel (62). The web panel (64) extends along the horizontal portion of the cutting line (60) in the panel (20).

  The panels (14, 20) work in cooperation to form a mirror image of the handle with respect to the vertical folding lines and cutting lines for stress guidance. Thus, the vertical folding curve (66) is a mirror image of the vertical folding curve (56) and functions to guide the lifting force into the bulk of the panel (14), thereby lifting the carton. Prevent tearing of the panel at times. The vertical folding line (66) has its upper end terminating at or near the cutting line (68) and its lower end at or near the lower cutting line (70). Terminated at The distance of the folding line (56, 66) from the associated corner edge (32, 34) is optimally such that an article (A) such as a can with a shoulder (B) is introduced into the carton. When the carton is lifted, the carton portion located on the shoulder when the carton is lifted can be adapted to the inclination of the shoulder. Because of this feature, cans and other articles with shoulders do not interfere with the stress guiding feature by folding lines (56, 66). The cutting line (68) is a mirror image of the cutting line (58), while the cutting line (70) is a mirror image of the cutting line (60). The upper web panel (72) associated with the cut line (68) is a mirror image of the web panel (62), while the web panel (74) associated with the cut line (70) is the web panel (64) of the web panel (64). It is a mirror image. When the blank (26) is three-dimensionalized into a carton, the lifting force generated by the handle (24) is distributed along the panel (12, 14) and distributed across the bottom wall panel (22). To do.

  The top wall panel (20) further has a triangular panel (76, 78) similar to the triangular panel (44, 46), and these triangular panels (76, 78) have similar functions. Yes. In addition, these triangular panels provide some relief from can distortion during shipping and damage to the carton. These triangular panels allow the carton to bulge slightly without compromising structural robustness. Also, by fixing the handle in the lateral direction, the lifting force is guided into the bulk of the material and can be guided directly to the carton's cutting line, folding line, corner part and fragile part. Absent. This lifting force is guided so that it can be accompanied by the bulk made by the material, based on dispersing the lifting force, without relying on special structural features to provide the required strength.

The blank (126) is similar to the blank (26) described above, and is similar to the blank (226) described later. The blank (26) results in a 12-pack carton where the article (can) (A) is placed parallel to the handle strap (24). On the other hand, the blank (126) is placed in a package formed from the blank (126) with articles such as cans, for example, with the top or bottom of each article abutting against the central top wall panel (120). A 6-pack carton is produced. The blank (126) is preferably divided into an end wall panel and a center panel by folding lines (128, 130). The top wall panel (120) is divided into a central top wall panel portion (120) and end wall portions (116, 118) by folding lines (128, 130). The side wall panels (112, 114) are divided into a central panel portion and an end wall panel portion. The top wall panel (120) is foldably connected to the side wall panel (112) along the fold line (132) and is connected to the side wall panel (114) along the fold line (134). It is connected so that it can be bent. The bottom wall panel (122a) is foldably connected to the side wall panel (112) along the folding line (138) and is connected to the bottom wall panel flap (122b) along the folding line (136). It is connected so that it can be bent.

  The side wall panel (122) has a plurality of score lines, thereby forming small triangular panels (144, 146). These triangular panels (144, 146) change the shape of the corner portion by bending, and avoid the corner portion from becoming a right angle. Similarly, the side wall panel (112) has a plurality of score lines, thereby forming small triangular panels (176, 178).

  Panel (120) has rounded (rounded) corners, resulting in an octagonal shape. In each corner portion of the panel (120), a notch is formed in the blank. However, the end wall portion of the panel (120) is connected to the panel (112, 114) along the folding line and connected to the end wall panel (116, 118) of the panel (120) by a score line. It is connected with the adjacent end wall part of a panel (120,122) through the made | formed web.

  The lateral handle strap (124) has a main strap portion formed between two notches in the top wall panel (120). The handle flaps (152, 154) are foldably connected to the handle (124) along the score line, and in the assembled state of the carton, the thickness of the strap is increased, Comfort can be increased. The entire handle assembly extends across the top wall panel (120) and onto the side wall panels (112, 114). Thereby, the handle assembly extends across the folding lines (132, 134). The handle assembly terminates in the sidewall panel (112) along the fold line (156). The folding line (156) has a central region and both ends at an angle toward the panel (112). For this reason, the folding line (156) has a concave shape, that is, an inverted “C” shape. Both ends of the inverted “C” shape terminate at or near the cutting lines (158, 160) located above and below. The cutting line (158) extends downward and obliquely toward the folding line (132), and then extends horizontally on the panel (120). Similarly, the cutting line (160) extends upward and obliquely across the panel (112) toward the folding line (132), and then extends horizontally on the panel (120). is doing. The ends of the cutting lines (158, 160) are preferably J-shaped to prevent tearing and to guide the lifting force into the bulk of the material forming the panel (112). The J-shaped back surfaces face each other. Therefore, these J-shaped curved portions extend in directions away from each other in the panel (112).

  The web panel (162) exists between the upper grip hole notch in the panel (120) and the horizontal portion of the cutting line (158) in the panel (120). The web panel (162) is defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the folding line, the main handle portion (124) can be lifted above the plane formed by the panel (120). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle (124), a second web panel (164) is foldably connected so that it can operate in cooperation with the web panel (162). The web panel (164) extends along the horizontal portion of the cutting line (160) in the panel (120).

  The panels (114, 120) act in cooperation to form a mirror image of the handle with respect to the vertical folding lines and cutting lines for stress guidance. Thus, the vertical folding line (166) is a mirror image of the vertical folding line (156) and functions to guide the lifting force into the bulk of the panel (114), thereby lifting the carton. Prevent tearing of the panel at times. The vertical folding line (166) has its upper end terminating at or near the cutting line (168) and its lower end at or near the lower cutting line (170). Terminated at The cutting line (168) is a mirror image of the cutting line (158), while the cutting line (170) is a mirror image of the cutting line (160). The upper web panel (172) associated with the cut line (168) is a mirror image of the web panel (162), while the web panel (174) associated with the cut line (170) is the web panel (164). It is a mirror image. When the blank (126) is three-dimensionalized into a carton, the lifting force generated by the handle (124) is not distributed along the end wall panels (116, 118), but the panels (112, 114). And distributed across the bottom wall panel (122).

  By fixing the handle laterally, the lifting force is guided into the bulk of the material and not directly against the carton's cutting line, folding line, corner or fragile part. This lifting force is guided so that it can be accompanied by the bulk made by the material, based on dispersing the lifting force, without relying on special structural features to provide the required strength.

  In FIG. 4, a lateral handle assembly is shown. The handle strap (224) is formed in a three-dimensional carton in a panel that is oriented as a side wall panel (214) of the carton, rather than the top wall panel of the carton (210). As described above, names such as “side wall” panel, “top wall” panel, and other panels are for convenience and are not intended to unnecessarily limit the scope of the present invention. The orientation of the carton (210) shown in FIG. 4 is based on the position of the outlet as shown in the blank of FIG. FIG. 5 shows a blank (226) that can form a carton (210). The blank (226) is preferably formed from a single piece of material and is divided into an end wall panel and a central panel by folding lines (228, 230). The top wall panel (220) is divided into a central top wall panel portion (220) and end wall portions (216, 218). The side wall panels (212, 214) are divided into a central panel portion and an end wall panel portion. The top wall panel (220) is foldably connected to the side wall panel (212) along the folding line (232) and to the side wall panel (214) along the folding line (234). It is connected so that it can be bent. The side wall panel (214) is foldably connected to the bottom wall panel (222a) along the folding line (236), while the bottom wall panel (222b) is along the folding line (238). The side wall panel (212) is foldably connected.

  The lateral handle strap (224) has a main strap portion formed between two notches in the side wall panel (214). The handle flaps (252, 254) are foldably connected to the handle (224) along the score line, and in the assembled state of the carton, the thickness of the strap is increased, Comfort can be increased. The entire handle assembly extends across the side wall panel (214) and onto the top wall panel (220) and the bottom wall panel (222). Thereby, the handle assembly extends across the folding line (234, 236). The handle assembly terminates along the fold line (256) in the panel (220). The fold line (256) terminates at or near the upper and lower cut lines (258, 260). The cutting line (258) crosses the panel (222) horizontally toward the folding line (234) and then extends horizontally on the panel (214). The cutting line (259) extends horizontally toward the main handle starting from the region where the cutting line (258) ends. However, the cutting line (259) is located closer to the handle than the cutting line (258). Thereby, discontinuity is formed between the cutting lines (258, 259). Similarly, the cutting line (260) crosses the panel (222) horizontally toward the folding line (234) and then extends horizontally on the panel (214). The cutting line (261) extends horizontally toward the main handle starting from the region where the cutting line (260) terminates. However, the cutting line (261) is located closer to the handle than the cutting line (260). Thereby, discontinuity is formed between the cutting lines (260, 261). The ends of the cutting lines (258, 260) are preferably J-shaped to prevent tearing and so that lifting forces can be guided into the bulk of the material forming the panels (220, 222). The J-shaped back surfaces face each other. Therefore, these J-shaped curved portions extend in directions away from each other.

  The web panel (262) exists between the cutting lines (258, 259), and the associated web panel (263) has a cutting line (259) and an upper grip hole notch in the panel (214). , Exist between. The web panels (262, 263) are defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the folding line, the main handle portion (224) can be lifted above the plane formed by the panel (214). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle (224), the web panels (264, 265) are foldably connected so that they can operate in cooperation with the web panels (262, 263). . The web panel (264) exists between the cutting lines (260, 261), and the associated web panel (265) has a cutting line (261) and a lower grip hole notch in the panel (214). And exist between.

  The panels (214, 220) work together to form a mirror image of the handle with respect to the vertical folding lines and cutting lines for stress guidance. Thus, the vertical folding curve (266) is a mirror image of the vertical folding curve (256) and functions to guide the lifting force into the bulk of the panel (222), thereby lifting the carton. Prevent tearing of the panel at times. The vertical folding line (266) has its upper end terminating at or near the cutting line (268) and its lower end at or near the lower cutting line (270). Terminated at As in the case of the folding lines (56, 66) in FIGS. 1 and 2 described above, the separation distance of the folding lines (256, 266) from the related corner edges (234, 236) is optimally, When a plurality of articles (A), such as a can with part (B), are introduced into a carton, the carton portion located on the shoulder when the carton is lifted can accommodate the shoulder inclination. It is supposed to be. Because of this feature, cans and other articles with shoulders do not interfere with the stress guiding feature due to the folding lines (256,266). The cutting line (268) is a mirror image of the cutting line (258), and the cutting line (269) is a mirror image of the cutting line (259). On the other hand, the cutting line (270) is a mirror image of the cutting line (260), and the cutting line (271) is a mirror image of the cutting line (261). The upper web panel (272) associated with the cutting line (268) is a mirror image of the web panel (262), and the web panel (273) is a mirror image of the web panel (263). On the other hand, the web panel (274) associated with the cutting line (270) is a mirror image of the web panel (264), and the web panel (275) is a mirror image of the web panel (265). When the blank (226) is three-dimensionalized into a carton, the lifting force generated by the handle (224) is distributed along the panels (220, 222).

  FIG. 6 shows another blank (326) for forming a carton with a lateral strap handle that can accommodate 12 bottles. The lateral strap handle is similar to the handle in the blank shown in FIGS. 2 and 5 except that the vertical folding line is straight. The transverse strap handle (324) has a main strap portion formed between two notches in the top wall panel (320). The handle flaps (352, 354) are foldably connected to the handle (324) along the cut line. The entire handle assembly extends across the top wall panel (320) and onto the side wall panels (312, 314). Thereby, the handle assembly extends across the folding line (332, 334). The handle assembly terminates along the folding line (356) at the sidewall panel (312) and terminates along the folding line (366) at the sidewall panel (314). The folding line (356) terminates at or near the upper and lower cutting lines (358, 360). The separation distance of the folding line (356, 366) from the associated corner edge is optimally, for example, a bottle with a shoulder (in the case of a bottle, the position of the shoulder is more than the can shoulder). When an article such as (low) is introduced into a carton, it is assumed that the carton portion located on the shoulder when the carton is lifted can accommodate the shoulder inclination. Because of this feature, bottles and other articles with shoulders do not interfere with the stress guiding feature due to the folding lines (356, 366). The cutting line (358) extends obliquely downward for a short distance toward the folding line (332) and then extends horizontally on the panel (320). Similarly, the cutting line (360) extends obliquely downward for a short distance toward the folding line (332) and then extends horizontally on the panel (320). The ends of the cutting lines (358, 360) are preferably J-shaped, and the J-shaped back surfaces face each other. Therefore, these J-shaped curved portions extend in directions away from each other in the panel (312).

  The web panel (362) exists between the upper grip hole notch and the horizontal portion of the cutting line (358) in the panel (320). The web panel (362) is defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the fold curve, the handle (324) can be lifted above the plane formed by the top wall panel (320). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle, the second web panel (364) is foldably connected so that it can operate in cooperation with the web panel (362). The web panel (364) exists along the horizontal portion of the cutting line (360) in the panel (320).

  The panels (314, 320) work in cooperation to form a mirror image of the handle with respect to the vertical folding lines and cutting lines for stress guidance. Therefore, the vertical folding line (366) is a mirror image of the vertical folding line (356). The vertical folding line (366) has its upper end terminating at or near the cutting line (368) and its lower end at or near the lower cutting line (370). Terminated at The cutting line (368) is a mirror image of the cutting line (358) with respect to the lateral axis of the handle and a mirror image of the cutting line (370) with respect to the longitudinal axis of the handle. On the other hand, the cutting line (370) is a mirror image of the cutting line (360). The upper web panel (372) associated with the cut line (368) is a mirror image of the web panel (362), and the web panel (374) associated with the cut line (370) is a mirror image of the web panel (364). It is. When the blank (326) is three-dimensionalized into a carton, the lifting force generated by the handle (324) is distributed along the panels (312, 314) and distributed along the bottom wall panel (322). .

  FIG. 7 also shows the lateral handle in a 12-pack bottle carton. The lateral strap handle is formed on the side wall so that a plurality of bottles can be accommodated side by side rather than standing upright. The handle is not symmetrical like the handle in the blank of FIG. 2, the left side is similar to the left side of the handle of FIG. 2, and the right side is configured differently. The right side does not have a vertical folding line, but has a handle strap connected directly to the panel. The side wall panel has a vertical folding line that branches the side wall panel. For this reason, in the assembled state of the carton, a part of the side wall panel is completely in the vertical direction, and the other part of the side wall panel is inclined inward to follow the outer shape of the bottle. There is no vertical folding line along the center of the handle. Therefore, when a blank is assembled into a carton, a space for inserting a hand is automatically formed. Alternatively, if the longitudinal portion of the handle follows the outer shape of the panel, a space for inserting a hand is formed along the vertical folding line on the left side of the blank.

  FIG. 7 shows a blank (426) that can form a carton. The blank (426) is preferably formed from a single piece of material and is divided into an end wall panel and a central panel by horizontal folding lines (428, 430). The top wall panel (420) is divided into a central top wall panel portion (420) and end wall portions (416, 418) by folding lines (428, 430). The side wall panels (412a, 412b, 414a, 414b) are divided into a central panel portion and an end wall panel portion. The top wall panel (420) is foldably connected to the side wall panel (412a) along the folding line (432). The side wall panel (412a) is foldably connected to the panel (412b) along the folding line (433), and the panel (412b) is connected to the bottom wall panel (422) along the folding line (438). It is connected so that it can be bent. The side wall panel (414b) is foldably connected to the bottom wall panel (422) and the side wall panel (414a) along the folding lines (436, 438). The top wall flap (439) is foldably connected to the side wall panel (414a) along the folding line (441).

  The blank is notched at each corner where the end wall flap (418) of the bottom wall panel (422) encounters the side wall panels (412a, 412b). The end wall portion of the panel (422) is connected to the connecting end wall portion of the panel (412b, 414b) through a strap connected to the related panel along the folding line. Thereby, at the time of the assembly of a carton, each end wall panel can be bent skillfully.

  At the time of three-dimensionalization, the side wall panel is first bent and the end wall panel is bent last. Thereby, a connection strap can be bent skillfully between end wall panels. A plurality of score lines (442) are formed in the side wall panel (414), thereby forming a break open access panel. The carton is three-dimensionalized with the bottom wall panel (422) as the bottom wall, and a plurality of bottles stand upright on the bottom wall panel (422). The side wall panels (412b, 414b) shall be substantially perpendicular to the bottom wall panel. Sidewall panels (412a, 414a) are folded inward at their respective tops to conform to the outer shape of the long necked bottle (411) with a narrower neck than the shoulder. The top wall flap (439) is folded over the top wall panel (420) and glued in place. A notch is present in the top wall panel (420) to receive the top wall flap (439), thereby preserving the material without reducing structural strength. The panels (420, 439) can have a plurality of notches (440) and a plurality of cuttable panels (441), and can receive the top of the bottle with the panels penetrating therethrough.

  The lateral handle strap (424) has a main strap portion formed between two notches in the side wall panels (412a, 412b). The handle flaps (452, 454) are foldably connected to the handle (424) along the score line to increase the thickness of the strap and increase the comfort of the grip holes. . The entire handle assembly extends from panel (412b) across panel (412a) and onto top wall panel (420). Thereby, the handle assembly extends across the folding line (432, 434). However, the folding line (433) does not intersect the handle, and can be gripped while the handle is extended. The handle assembly terminates at the sidewall panel (412) along the fold line (456). The folding line (456) has a central region and opposite ends that are angled toward the panel (420). For this reason, the folding line (456) has a concave shape, that is, an inverted “C” shape. Both ends of the inverted “C” shape terminate at or near the cutting lines (458, 460) positioned above and below. The distance from the associated corner edge (432) to the fold line (456, 266) optimally lifts the carton when multiple articles are introduced into the carton, for example, a bottle with a heel. It is assumed that the carton portion located on the heel at this point can be adapted to the heel inclination. Because of this feature, cans and other articles with heels do not interfere with the stress guiding feature of the fold line (456). The cutting line (458) extends downward and obliquely toward the folding line (432), and then extends horizontally on the panel (412a). Similarly, the cutting line (460) crosses the panel upward and diagonally toward the folding line (432) and then extends horizontally on the panel (412a). The ends of the cutting lines (458, 460) are preferably J-shaped to prevent tearing and to guide the lifting force into the bulk of the material forming the panel (420). The J-shaped back surfaces face each other. Therefore, these J-shaped curved portions extend in directions away from each other in the panel (420).

  The web panel (462) exists between the upper grip hole notch in the panel (412) and the horizontal portion of the cutting line (458) in the panel (412). The web panel (462) is defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the folding line, the main handle portion (424) can be lifted above the plane formed by the panel (412). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle (424), a second web panel (464) is foldably connected so that it can operate in cooperation with the web panel (462). Web panel (464) extends along a horizontal portion of cut line (460) in panel (412). When the blank (426) is three-dimensionalized into a carton, the lifting force generated by the handle (424) is distributed along the panels (412b, 420). During transport, the carton can be lifted on the side so that each bottle is oriented horizontally rather than vertically.

  FIG. 8 shows a blank (526) that can form a carton for packing six items, such as 1 liter bottles. On the one hand, the top wall panel (520) is foldably connected to the side wall panel (512) along the folding line (532), and on the other side, along the folding line (534), the side wall panel ( 514) is foldably connected. The side wall panel (514) is foldably connected to the bottom wall panel (522a) along the folding line (536). The bottom wall panel (522b) is foldably connected to the side wall panel (512) along the folding line (538).

  The lateral handle strap (524) has a main strap portion formed between two notches in the top wall panel (520). The entire handle assembly extends across the top wall panel (520) and onto the side wall panels (512, 514). Thereby, the handle assembly extends across the folding line (532, 534). The cut line (558) extends slightly downward toward the fold line (532) in the horizontal direction and then extends to the panel (520). Similarly, the cutting line (560) traverses the panel (512) slightly upwards toward the fold line (534) in the horizontal direction and then extends to the panel (520). The ends of the cutting lines (558, 560) are preferably J-shaped to prevent tearing and to guide the lifting force into the bulk of the material forming the panel (512). The J-shaped back surfaces face each other. Therefore, these J-shaped curved portions extend in directions away from each other in the panel (512).

  The web panel (562) exists between the upper grip hole notch in the panel (520) and a portion of the cut line (558) in the panel (520). The web panel (562) is defined by a plurality of vertical folding lines and a plurality of horizontal cutting lines. When folded along the folding line, the main handle portion (524) can be lifted above the plane formed by the panel (520). Thereby, a space for inserting a hand is formed, and the carton can be lifted. Similarly, along the underside of the handle (524), a second web panel (564) is foldably connected so that it can operate in cooperation with the web panel (562). Web panel (564) extends along a portion of cut line (560) in panel (520). The cutting line (568) is a mirror image of the cutting line (558) and the cutting line (570) is a mirror image of the cutting line (560) with respect to the lateral axis of the handle. The upper web panel (572) associated with the cut line (568) is a mirror image of the web panel (562), and the web panel (574) associated with the cut line (570) is a mirror image of the web panel (564). It is. When the blank (526) is three-dimensionalized into a carton, the lifting force generated by the handle (524) is distributed along the panels (512, 514) and along the bottom wall panels (522a, 522b). scatter.

  FIG. 8 shows a blank for forming a wrapping type carton without an end wall panel. The top wall (520) has a plurality of openings (576) for receiving bottle necks. Each opening (576) is preferably circular, with a cleavable portion attached adjacent to allow the opening to expand for a larger neck. As shown, six openings are provided. Side wall (512) has a row of break lines (578) that form pull tabs for access to the contents of the carton. The bottom wall panels (522a, 522b) have a notch forming panel (580) for engaging with the bottom of the bottle in a three-dimensional state to prevent positional deviation of the bottle. The bottom wall panel further has a locking tab.

  As illustrated in the various embodiments described above, the strap portion of the carton handle (24, 124, 224, 324, 424, 524) is longer than the longitudinal orientation relative to the panel. The case where it is oriented transversely to the thickness and width can be made wider. Wide handles are stronger than narrow ones and can be formed from a thinner material compared to narrow handles. Similarly, the handle end that forms the T-shaped connection to the carton can be wider than when the handle is disposed longitudinally. The plurality of sidewalls through which stress is guided in each embodiment typically provides the largest continuous surface area that allows stress distribution. Typically, the sidewall panels do not have joints that are bonded to other panels. Alternatively, if a joint is present, the stressed sidewall provides sufficient surface area to function to substantially distribute the stress.

  It will be appreciated that a carton with a lateral strap handle and a blank for forming such a carton are provided. By placing the strap handle laterally instead of longitudinally, the lifting force and package weight are distributed over a larger area of the side panel. The carton includes a center panel, a left panel that is foldably connected to the center panel along the left fold curve, and a right panel that is foldably connected to the center panel along the right fold curve. A strap handle formed from a center panel, a left panel, and a right panel. The handle extends across the central panel between the left and right panels. A web panel attached to the handle and the central panel connects the handle and the central panel. These web panels, typically in an even set of 4 or 8 web panels, are used and are arranged symmetrically with respect to the longitudinal and transverse axes of the handle. The web panels are foldably connected to the handle and the center panel, and are extended from the center panel, thereby positioning the handle at a higher position than the center panel. The handle is bent along the left and right folding lines. In some embodiments, the left portion of the handle has a concave curvature that opens toward the left panel, and the right portion of the handle has a concave curvature that opens toward the right panel. In other embodiments, the left portion of the handle has a concave curvature that opens toward the left panel, and the right portion of the handle is integral with the right panel. In either embodiment, the left and right portions of the handle distribute the load evenly to the left and right panels, respectively. The left-center-right panel combination may be a side wall-top wall-side wall panel combination or a top wall-side wall-bottom wall panel combination.

  The blank for the product carton has a central panel with a left turn along the left edge and a right turn along the right edge. The left panel is foldably connected to the center panel along the left fold curve, and the right panel is foldably connected to the center panel along the right fold curve. The strap handle is formed from a central panel, a left panel, and a right panel, and extends across the central panel between the left panel and the right panel. In a preferred embodiment, at least four web panels are foldably attached to the handle and the central panel and connect the handle and the central panel. These web panels are arranged symmetrically with respect to the longitudinal and transverse axes of the handle. The handle is bent along the left and right folding lines. In some embodiments, the left portion of the handle has a concave curvature that opens toward the left panel, and the right portion of the handle has a concave curvature that opens toward the right panel. In other embodiments, the left portion of the handle has a concave curvature that opens toward the left panel, and the right portion of the handle is integral with the right panel.
