  The handle structure includes a handle strap formed from at least three portions of the carton. The three parts include at least one large end flap and two small end flaps. Preferably, the small end flap of the assembled carton is located inside the large end flap, i.e. between the large end flap and the contents of the carton. A blank 1 having a panel arrangement for forming a carton with such a handle structure is shown in FIGS.

  The blank 1 with this preferred embodiment of the handle structure comprises a series of panels connected in a straight line to form the top, side and bottom walls of the carton 100 (FIG. 4), each The adhesive panel 2, the top wall panel 4, the first side wall panel 6, the bottom wall panel 8, and the second side wall panel 10 are connected to each other by folding lines 20, 22, 24, and 26.

  The plurality of end flaps are foldably connected to one or both of the respective end edges of the series of wall panels connected in a straight line. A plurality of end flaps along at least one edge of a series of wall panels connected in a straight line form various portions of the handle structure, as will be described below. If desired, the opposing edges of a series of wall panels connected in a straight line can be provided with a plurality of end flaps for closing that end of the carton. These end flaps can be provided with access means as required.

  The first large end flap 30 is foldably connected to the top wall panel 4 with respect to the fold line 28, and the second large end flap 32 is foldably connected to the bottom wall panel 8 with respect to the fold line 29. The The first large end flap 30 includes a first strap member 34 that is partially separated from the first large end flap 30 by three dividing lines 54, 60, 60. Separated and connected to the first large end flap 30 by tabs 50 and cuts 53 (FIGS. 2 and 2A). Similarly, the second large end flap 32 includes a second strap member 36 that is separated from the second large end flap 32 by three dividing lines 54, 60, 60. Partially separated and connected to the second large end flap 32 by a tab 50 and a cut portion 53. This connection of those panels is described in more detail below.

  The first strap member 34 and the second strap member 36 are provided on the first large end flap 30 and the second large end flap 32 farthest from the series of panels connected in a straight line of the blank 1. Arranged along each free edge. Each of the first strap member 34 and the second strap member 36 is substantially separated from each of the first large end flap 30 and the second large end flap 32 by two dividing lines 60, 60. The two dividing lines 60, 60 extend from respective opposing side edges of the first large end flap 30 and the second large end flap 32 toward the central region thereof. The dividing lines 60 are blocked by the cut portion 53 adjacent to the side edges of the first large end flap 30 and the second large end flap 32. These dividing lines 60 stop before they meet each other and terminate with a small “J” shaped cut 62. The components that extend away from the points on their “J” shaped cuts 62 are fold lines 58 connected to each other by further dividing lines 54. The respective contours of the first strap member 34 and the second strap member 36 are therefore partially defined by the dividing line 60, the fold line 58, and the dividing line 54.

  The tab 50 is foldably connected to the first strap member 34 and the second strap member 36 with respect to the fold line 58, and is connected to the first large end flap 30 or the second along the opposing fold line 52. A large end flap 32 is foldably connected. A fold line 52, which is foldably connected to the first large end flap 30 or the second large end flap 32, is inclined with respect to the fold line 58. With respect to them, they are foldably connected to the first strap member 34 or the second strap member 36. The end points on these two fold lines 52, 58 are connected by part of parting line 54 or part of parting line 60 to define the side edges of tab 50 accordingly.

  A dividing line 54 that defines a portion of the end edges of the first strap member 34 and the second strap member 36 also defines the end edge of the handle flap 56. One such handle flap 56 extends from each of the first strap member 34 and the second strap member 36, with each fold line 70 extending between terminations on the split line 54, and Each of the first strap member 34 and the second strap member 36 is foldably connected. The end of each handle flap 56 includes a fold line 55 that divides the handle flap into a central main portion that is foldably connected to foldable portions on both sides. These fold lines 55 are fed into the carton to match the user's hand and / or when they are folded inwardly, which may partially obstruct the passage of the handle flap 56. The handle flap 55 is deformed so as to be deformed around a plurality of articles.

  Each of the first strap member 34 and the second strap member 36 is substantially rectangular and includes the handle flap 56 described above. On both sides of the handle flap 56, the first strap member 34 and the second strap member 36 extend to the end edges of the corresponding first large end flap 30 or second large end flap 32. Each of the first strap member 34 and the second strap member 36 includes a substantially rectangular portion, and the substantially rectangular portion of the first large end flap 30 or the second large end flap 32. The width of the top wall 4 or the bottom wall 8 that extends substantially over the respective width and is preferably foldably connected to the first large end flap 30 and the second large end flap 32. It corresponds to almost the whole. This rectangular portion provides a grippable handle strap 102 (FIGS. 3A-6) of the handle structure when formed in the manner described below.

  The first small end flap 80 and the second small end flap 82 can be folded to the edges of the first side wall panel 6 and the second side wall panel 10 via fold lines 84 and 88, respectively. Connected to. Each of the first small end flap 80 and the second small end flap 82 is a tapered flap that corresponds to the corresponding first side wall panel 6 and second side wall panel 10. And two spaced apart parallel split lines 88, 89 that are narrowed away from and located on either side of the midpoint of the first small end flap 80 or the second small end flap 82. The dividing lines 88, 89 substantially connect each of the first small end flap 80 and the second small end flap 82 to three portions, ie, side portions 90 on either side of the central reinforcing portion 92. To divide. This minimal degree of connection between the central reinforcing portion 92 and the side portion 90 leaves the small cut portions 94 that connect the central reinforcing portion 92 to the corresponding side portion 90 on each side, as is. Maintained by a small break at the dividing lines 88, 89. The dividing lines 88, 89 extend shortly into the adjacent first side wall 6 or, in some cases, into the adjacent second side wall 10. From the respective end of the first dividing line 88 or the second dividing line 89 in the corresponding first side wall 6 and second side wall 10, the fold lines 91, 93 are connected to the first side wall 6 or the second side wall 6. It extends at a predetermined angle so as to terminate at the side edges 22, 24, 26, 27 closest to the side wall 10. The dividing lines 91, 93 direct the stress from the first large end flap 30 and the second large end flap 32 when the handle structure is in use as described below. Provided to.

  A plurality of adhesive regions G1-G6 are also shown in FIG. The bonding area G1 is a relatively large bonding area disposed on the second strap member 36 so as to allow the second strap member 36 to be fixed to the first strap member 34. Regions G2-G6 are relatively small bond areas provided for fixation between the small end flaps 80, 82 and the large end flaps 30, 32 or strap members 34, 36, respectively. Details of how this fixation is achieved are given in detail below.

  The folding operation for assembling the handle structure from the blank 1 shown in FIG. 1 is shown in two steps in each of FIGS. FIG. 2 shows the partial assembly of the carton, in which the first side wall panel 6 and the second side wall panel 10 in the carton are the first side wall panel 6 and the second side wall panel. 10 is folded with respect to each fold line 24, 26 so as to be in a perpendicular relationship to the bottom wall panel 8. Preferably, the top wall panel 4 is also folded perpendicular to the first side wall panel 6 with respect to the fold line 22 so that the adhesive panel 2 is relative to the top wall panel 4 with respect to the fold line 20. It can be folded and secured to the inner or outer part of the second side wall panel 10 thereby forming a tubular structure. The first small end flap 80 and the second small end flap 82 are folded so that the first small end flap 80 and the second small end flap 82 are flush with each other. Folded inside the carton (or tubular structure) 100 with respect to the lines 84, 86. As shown in FIG. 2, the first two adhesive regions G2, G3 of each of the first small end flap 80 and the second small end flap 82 are connected to the second strap member 36 and the first A small end flap 80 and a central reinforcing portion 92 of the second small end flap 82 are interposed. Adhesive is applied to the bonded areas G2 and G3 prior to folding of the second small end flap 32, thereby maintaining the fixation between the two when it is in contact. Similarly, the adhesive may be applied to the side portions 90 of the first small end flap 80 and the second small end flap 82 adjacent to the bottom wall panel 8 before folding the second large end flap 32. It is applied to the adhesive region G4 disposed above. The second large end flaps 32 then bring the second large end flaps 32 into contact with the portions of their first small end flaps 80 and second small end flaps 82 in the same plane. In this way, the folding line 29 is bent relative to the bottom wall panel 8. Thus, when the second large end flap 32 is folded with respect to the fold line 29, the second strap member 36 is the central reinforcement portion of the first small end flap 80 and the second small end flap 82. It is fixed to four adhesive regions G2 and G3 with respect to 92, and two adhesive regions G4 with respect to the side portion 90 of the first small end flap 80 and the second small end flap 82. It will be in a fixed state.

  The adhesive is applied to the first adhesive region G1 as described above to secure the first strap member 34 and the second strap member 36 together, and the adhesive is applied to the first small end flap 80. And applied to the fifth adhesive region G5 so as to secure the portion of the first strap member 34 to the respective central reinforcing portion 92 of the second small end flap 82. In addition, the adhesive is applied to the first large end flap 30 against the respective side portions 90 of the first small end flap 80 and the second small end flap 82 adjacent to the top wall panel 4. It applies to the 6th adhesion field G6 so that a portion may be fixed.

  If not already so folded, the top wall panel 4 is then folded to be perpendicular to the first side wall panel 6 so that the top wall panel 4 faces the bottom wall panel 8. The first large end flap 30 so that the first large end flap 30 is in contact with the portions of the first small end flap 80 and the second small end flap 82 in the same plane. The fold line 28 is bent. The portion of the first strap member 34 is thereby in contact with the portion of the second strap member 36 in the same plane. The first strap member 34 is maintained in a coplanar arrangement with the first large end flap 30 and is in contact with a portion of the second strap member 36. The adhesive applied to the adhesive regions G1, G5, and G6 secures the first strap member 34 and the second strap member 36 to each other and ties the first large end strap 30 portion to the first small end. Secure to the remaining side portions 90 of the part flap 80 and the second small end flap 82.

  Following their folding and bonding operations, the composite end wall of the carton is completed. The composite end wall is formed from a first large end flap 30 and a second large end flap 32 and a first small end flap 80 and a second small end flap 82. This composite end wall provides part of the handle structure including the handle strap 102 (see FIGS. 3 and 3A). The handle strap 102 includes a first strap member 34 and a second strap member 36, a first small end flap 80 and a central reinforcement portion 92 of the second strap member 82, and a dividing line 88, 89. Each of the first side wall panel 6 and the second side wall panel 10 (FIGS. 4 and 5). As best illustrated in FIG. 3, the central portion of the handle strap 102 has a two-layer thickness formed from a first strap member 34 and a second strap member 36, whereas The portions on opposite edges are each formed from a first strap member 34 and a second strap member 36, and respective central reinforcement portions of the first small end flap 80 and the second strap member 82, respectively. Having a three layer thickness.

  As can be seen in FIG. 3, the central portion of the handle strap 102 has a generally rectangular shape and includes handle flaps 56 on either side thereof. The handle flaps 56 can be folded relative to the edge of the central portion to form an opening 104 (as shown in FIGS. 4 and 5), and the user's finger can The strap 102 can be inserted into its opening 104 to allow it to be grasped.

  The tab 50 connecting the handle strap 102 (or the first strap member 34 and the second strap member 36) with the first large end flap 30 and the second large end flap 32, respectively, is a composite end wall. Of the first strap member 34, i.e., not formed in vertical alignment with any portion of the first small end flap 80 or the second small end flap 82. Alternatively, it is not formed by vertical alignment with any overlapping portion of the second strap member 36. A fold line 52 foldably connects the tab 50 to the first large end flap 30 and the second large end flap 32 and to the first strap member 34 and the second strap member 36. , 58 can be omitted. In this example, the stress generated by lifting the carton by the handle strap 102 causes the stress between the tabs 50 and their connected panels 30, 32, 34, 36 to overwhelm the original strength of the material. Will transform the connection.

  4 and 5 show the assembled carton 100 handle structure in which the handle flap 56 is folded inwardly of the carton 100 to provide two handle openings 104. The handle structure can always be used to grip the carton 100 and lift the carton 100 by the user, as shown in FIGS.

  In use, the operation of the handle structure is best shown in FIGS. The drawings illustrate the result of the bending of the tab 50 and the deformation of the portions of the first side wall 6 and the second side wall 10 in response to the action of a force on the central portion of the handle strap 102. As can be seen from those drawings, the force on the central portion lifts the three layers of the strap member outwardly away from the carton contents, and during the process the first large end flap 30 and The cut 53 that partially connects the second large end flap 32 to the first strap member 34 and the second strap member 36 is broken. Those three layers can be folded with respect to their side edges 84, 86 connecting the first small end flap 80 and the second small end flap 82 to the first side wall 6 and the second side wall 10. Connect to. When this force is applied, the portion 106 (FIGS. 4 and 5) of the first side wall 6 and the second side wall 10 between the dividing lines 88 and 89 is deformed in the inward direction. The stress placed on the material of the handle structure is therefore directed at the ends of the dividing lines 88, 89 and subsequently by the inclined fold lines 91, 93 by the first side wall 6 and the second side. Directed to the edges 22, 24, 26, 27 of the two side walls 10, respectively. This force is an integral part of the cut portion 94 that maintains the connection between the central reinforcement portion 92 and the side portion 90 at their respective sides of the first small end flap 80 and the second small end 82. Overwhelm, thereby freeing the central reinforcement portion 92 for independent foldable connections of the side portions 90 that substantially hold in the plane of the composite end wall

  The tab 50 is foldably connected to each of the first strap member 34 and the second strap member 36 and the central portion of the handle strap 102 is spaced apart from the plane of the composite end wall of the carton 100. Then, the first large end flap 30 and the second large end flap 32 are adjacent to each other so as to be foldable. The angle between the first fold line 52 and the second fold line 58 defining the opposite ends of the tab 50 is such that their original planar state in the plane of the end wall of the carton 100. While maintaining a physical connection thereto, the first large end flap 30 and the second large end flap 32 are promoted. In doing so, the carton maintains the aesthetic appeal of the end of the carton by preventing the bending of the first large end flap 30 and the second large end 32. Otherwise, it will detract from the aesthetic appeal and will lead to large openings that cannot be desired through the holes left by the extended handle structure. Through the large opening, an undesired appearance of multiple items in the container may occur.

  Thereby, the handle structure is provided by means provided with a multi-layered strap capable of gripping the material. The multi-layer handle strap 102 provides sufficient space beneath it for insertion of the user's fingers. The weight of the carton 100 is supported by the handle structure, and the stress placed thereon is advantageously directed to the side wall of the carton, while the tab 50 is connected to the handle structure and the first large end. The connection between the flap 30 and the second large end flap 32 is maintained, otherwise forming an end closure at that end of the carton 100. The reinforcing tabs act to provide a three-layered portion at both ends of the two-layer grippable strap 102, thereby assisting in the robustness of the handle structure. The tab 50 connecting the first strap member 34 and the second strap member 36 with the first large end flap 30 and the second large end flap 32 is a single layer. In the preferred embodiment described above, the four panels of the carton are used to form a handle strap and are secured together in specific areas to form the desired arrangement.

  The carton can be supplied with a plurality of articles, a plurality of generally cylindrical articles such as cans and bottles. The handle structure prevents multiple items from appearing accidentally through the corresponding ends of the carton. At the opposite ends of the carton, some end closure means can be employed to enclose multiple items, if desired. Furthermore, the access means can be provided in the carton, which access means can form one or more separable parts of one or more panels of the carton 100, for example, which are separable The removal of such parts occurs at the opening through which a plurality of articles can be removed.

  It is envisioned that the supply of a plurality of articles to the carton may take place before, or at any stage during, or after the folding operation. In the embodiment illustrated in FIG. 4, the carton 100 is supplied with a group of cans “C” arranged in a 2-by configuration to form a package. More specifically, the plurality of cans are arranged in two rows such that the cylindrical axes of the plurality of cans are substantially parallel to each other. The upper wall 4 of the carton 100 is disposed along the upper surface of the plurality of cans “C”. The bottom wall 8 is disposed along the bottom of the plurality of cans “C”, and the first side wall 6 is disposed along the rounded walls of the plurality of cans “C” in one of the two rows. The two side walls 10 are arranged along the other rounded wall of the two rows. The composite end wall is disposed along the rounded wall at each end of the two rows of cans. The handle strap extension 102 is positioned on the end can “C” so that the opposite ends of the handle strap 102 are positioned adjacent to the rounded wall of the adjacent end can “C”. It extends substantially perpendicular to the axis.

  A second preferred embodiment of the handle structure is shown in FIG. FIG. 7 shows a second blank 101 for forming a carton, and it is the handle structure according to this second preferred embodiment that is defined within the plurality of panels.

  The handle structures according to the first and second embodiments are substantially similar and only the differences will be described below.

  In the first strap member 134 and the second strap member 136 in the second embodiment, the handle flap 156 does not completely fill the opening through which the user's finger is inserted into the assembled carton. Therefore, the end edge of the handle flap 156 is partly defined in the opening by a parting line 171 in a partial manner, the parting line 171 being the first strap member 134 or the second strap. Crossing the end of a fold line 170 that foldably connects the handle flap 156 to each of the members 136 and then substantially with the end portion of the fold line 170 to define adjacent side edges of the tab 150. Continue to extend coaxially. The dividing line 171 terminates at a “J” -shaped cut at the first strap member 134 and the second strap member 136. The “J” -shaped cut of the dividing line 171 is formed in accordance with the stress placed on the first strap member and the second strap member by using the handle structure to lift the carton. The tearing of the first strap member and the second strap member is prevented.

  The dividing line 160 at the first large end flap 130 and the second large end flap 132 preferably does not terminate with a “J” shaped dividing line, but rather defines an adjacent edge of the tab 150. And ends with a straight dividing line that terminates at the distal corner.

  The second small end flap 182 is a composite panel formed from the first half 182A and the second half 182B, the first half 182A and the second half 182B being the first half 182A. In order to remove the requirement of the additional adhesive panel 2 of the embodiment, it can be fixed to each other. Further, each of the first small end flap 180 and the second small end flap 182 includes an additional dividing line 196, 197, which is the terminal “ Matches the “J” shaped cut. Thus, in this second embodiment, the first small end flap 180 and the second small end flap 182 can overlap portions of the first strap member 134 and the second strap member 136. . In the first strap member 134 and the second strap member 136, a “J” -shaped dividing line is formed, whereby the end portions of the dividing line 171 and the dividing lines 196, 197 are aligned with each other.

  As can be seen from FIG. 7, the dividing lines 188, 189 in the first small end flap 180 and the second small end flap 182 do not extend into the side walls of the carton. Fold lines 191 and 193 extend to the sidewalls from the intersection of the fold lines connecting the first small end flap 180 and the second small end flap 182 and their dividing lines. Therefore, during operation, the handle structure does not include a deformed portion of the sidewall.

  The folding operation required for assembling the carton having the handle structure according to the second embodiment is the same as the above-described folding operation.

  Various modifications may be made within the scope of the disclosure of the present application, for example, the size and shape of the panels and openings can be adjusted to accommodate multiple articles of different sizes or shapes, Can be understood. It is envisioned that two embodiments of the handle structure have been described above and that the components of each embodiment can be combined as needed. For example, the “J” -shaped cutting portion of the dividing line 171 can be adopted, and at the same time, the “J” -shaped dividing line 62 of the first embodiment can be maintained.

  In other embodiments of the present disclosure, it is envisioned that the number of blank material thicknesses used to form different portions of the handle structure can be varied. For example, it is envisioned that the central portion of the handle strap 102 can be provided by a single layer strap member that replaces the combined first strap member 24 and second strap member 26 described above. In such an alternative embodiment, a large series of panels are connected to each other in the manner described above in a foldable manner to one of the top wall 4 and the bottom wall 8 of the carton, so that the large end It would be possible to provide both a flap and an intermediate strap member. If desired, an adhesive flap that can be foldably connected to the other of the top wall 4 and the bottom wall 8 can be included, the opposing ends of the straight series of panels being Can be fixed to them. Similarly, the thickness of the three or more carton materials may include the center of the handle strap 102 by including one or more additional reinforcing panels that are vertically aligned with at least a portion of the central portion thereof. Can be employed to provide parts.

  The thickness of the three layers of the handle strap 102 where the thickness of the two layers of the central portion is fixed to the central reinforcing portion 92 is varied to provide a greater or lesser thickness of carton material. Can. This can be accomplished by providing an additional reinforcing panel that is disposed between the central portion and the central reinforcing portion 92.

  It is also envisioned that the handle structure can be provided on different walls of the carton, rather than the end walls described above. For example, the same arrangement of panels in the blank can be employed to form a composite top wall of a carton.

  The fold line 70 that foldably connects the handle flap 56 to the first strap member 34 and the second strap member 36 may alternatively comprise one or more parting line portions. In addition to the further weak connection between the handle flap 56 and each of the first strap member 34 and the second strap member 36, their dividing line is also adjacent to the end of each edge of the handle flap 56. So that the ends of the handle flaps 56 can be separated from each of the first strap member 34 and the second strap member 36. In this way, any fold line provided in the handle flap 56, such as the fold line 55 described above, matches the handle flap 56 better to the user's hand and / or the plurality of articles inside the carton. Would be able to deform at that end.

  The exemplary shapes of the handle flaps 56 and the indirect openings in the carton 100 when the handle flaps 56 are folded inwardly are suitable, for example, for different fingers of the inserted user's hand, It can be modified as needed to suit the desired application. Alternatively, the handle flap 56 can be omitted entirely and can be replaced, for example, with a single continuous dividing line that defines an opening.

  It is envisioned that while tabs 50 are described in the above embodiments, any shape of tabs can be used because they have opposing edges that are at a predetermined angle relative to each other. The different shapes can lead to different forces placed on the end edges of the first large end flap 30 and the second large end flap 32 when the central portion 102 is in the in-use position. I will.

  A J-shape that terminates a dividing line 60 that defines the adjacent edge portions of the first large end flap 30 and the second large end flap 32 and the first strap member 34 and the second strap member 36. The shaped cut is not an essential feature and may be completely removed and replaced with a different cut stroke path.

  Beyond the edges of the first small end flap 80 and the second small end flap 82, the first small end flap 80 and the second small end flap 82 are connected to the corresponding first side wall 6. Alternatively, the extension of the dividing lines 88, 89 that divide into the second side wall 10 may effectively include a greater or lesser number of side walls of the carton, as required. It can be omitted completely or may be changed in its length.

  As used herein, directions such as “top”, “bottom”, “front”, “back”, “side”, “inside”, “outside”, “upward”, and “downward” It will be appreciated that this criterion does not limit each panel to its orientation, but merely serves to distinguish those panels from each other. Any reference to a foldable connection is not necessarily to be construed as referring to only a single fold line; in fact, a foldably connected connection is not the technical disclosure of the present disclosure. It can be formed from one or more of the following short slits, foldable lines, or fold lines without departing from the scope.
