During the assembling and packaging of the article B, the green sheet 10 is made so that each heel opening A3 can respectively accommodate the bottom of a corresponding article B, so that the article B is held in the carton 90. Bending the first heel tongues 54 helps to hold the articles B. The way to achieve this is to first bend the first and second base plates 12, 28 outwards, so that the first heel tongues 54 extend inward, and then bend the first and second base plates around a group of objects. When the first and second side panels 16 and 24 are used, the first heel tongues 54 will be located below a corresponding article B. Subsequently, the first and second bottom plate pieces 12, 28 are bent around the bottom of the article group. When doing so, the first heel tongue pieces 54 are joined to the corresponding article B, and follow itself. The folding line 55 is used to hinge to the corresponding one of the first and second bottom plates 12 and 28 and then bend.

The first heel tongue 54 facilitates the heel or bottom of an article B to be easily fixed or locked in position.

The second tongue pieces 50a, 50b and the pair of opposite heel tongue pieces 52a/56a, 52b/56b are deformed or bent outwards around the contained article B. The second tongues 50a, 50b and the opposite heel tongues 52a/56a, 52b/56b can protect the heel or lower portion of the article B accommodated in the heel opening. In addition, the second tongues 50a, 50b and the opposing heel tongues 52a/56a, 52b/56b can reduce the stress on the substrate or divert the force it bears, so that when the carton 90 is used, it can be reduced. Possibility of tearing to spread.

The blank 10 may include at least one deformed or bent structure FS. The green sheet 10 shown includes several bending structures FS, and can optionally include four bending structures FS. Each bending structure FS forms a deformed corner area of the carton 90, and can optionally form a lower or bottom corner area. The bending structure FS includes a configuration composed of several folding lines, and is suitable for eliminating or reducing the sharpness and/or rigidity of a corner or edge of the carton 90. This can be helpful when transporting or carrying the carton 90 in a carrying bag, especially but not limited to carrying bags made of plastic, paper or similar sheets. The bending structure FS can prevent or reduce the possibility that the carton 90 may perforate, tear, or otherwise puncture or damage the material forming the carrying bag. It should be understood that if the carrying bag has any puncture holes, its load capacity may be reduced; once it is reduced, the tear may spread. This may cause the carrying bag to fail, causing the carton 90 or other items placed in the bag to accidentally fall out, thereby causing the possibility of damage.

The structure of each bending structure FS is substantially the same, so only the bending structure FS provided on the second side plate 24 and the bending structure FS shown in FIG. 2 will be described below.

The bending structure FS includes pressure release tongues 60, 66, 68 formed from the second side plate 24 and the fourth corner plate 26. The bending structure FS includes a first pressure releasing tongue 68 and a second pressure releasing tongue 66 formed from the second side plate 24. A third pressure release tongue 60 is formed from the fourth corner plate 26.

In the embodiment where the corner plate 26 is omitted, at least a part of the third pressure release tongue 60 can be formed by the second side plate 24 and another part by the second bottom plate 28, or the whole It is formed by the second side plate piece 24.

One part of the first pressure release tongue 68 is defined by a first fold line 69 provided on the second side panel 24, and the other part is defined by a first fold line 69 provided on the second side panel 24. Two fold lines 67 define.

One part of the second pressure release tongue 66 is defined by the second fold line 67, and the other part is defined by the fold line 29 that hinges the second side panel 24 to the fourth corner panel 26 The end 29a is defined.

A part of the third pressure release tongue 60 is defined by the end 29a of the fold line 29 that hinges the second side plate 24 to the fourth corner plate 26, and the other part is defined by a first Three fold lines 49 are defined.

The third fold line 49 extends from a second or lower end of the first pressure relief cut 62a. The third fold line 49 may extend to one of the first or outer ends of the end 31 a of the fold line 31 where the fourth corner panel 26 is hinged to the second bottom panel 28.

The first fold line 69 is set to diverge from the second fold line 67. Moreover, the first and second folding lines 69 and 67 diverge toward the longitudinal or free side edge of the green sheet 10. In addition, the end of the first and second fold lines 69, 67 that are close to each other is the first end, and the end that is far away from each other is the second end.

The first, second, and third folding lines 69, 67, 49 each extend inward from a free end edge E1 of the green sheet 10.

The pressure release tongues 60, 66, 68 are arranged between a longitudinal or free end edge E1 of the blank 10 and an adjacent heel structure N3.

The bending structure FS enables a part of the second side plate 24 (and the second corner plate 26 if provided) to bend or deform around the end of an endmost adjacent article B , Causing the free edge of the part to be closer to the outermost article B. This reduces the rigidity of the outside or end area of the part, so that it is easy to deform. In this way, during the loading or carrying of a carrying bag, the possibility of puncturing the wall of the carrying bag or causing other damages by the lower corner of the carton 90 loaded therein is reduced. Therefore, the practice of "double bagging" can also be reduced, that is, a first carrying bag is put into a second carrying bag, in order to produce a stronger two-layer carrying bag.

The top plate 20 may include an optional handle structure H. The handle structure H further includes a finger tab 70. The finger protection piece 70 is hinged to the top plate piece 20 by a folding line 71, and a part of it is bounded by a cutting line or cutting line 73. The cutting line 73 may include extension portions 73 a and 73 b extending from the finger protection sheet 70 and substantially extending outward from the folding line 71. Each of the extension portions 73a, 73b can have a "J" or "C"-shaped cut as the end point. In addition, the extension portions 73a, 73b can be provided with a pressure relief device, so as to control or guide the load force when the handle H is used. This can alleviate the tearing and spreading of the top plate 20 when the handle is used.

Optionally, the top plate 20 may include a first notch or notch R1 pressed from a first free end edge. Optionally, the top plate 20 may include a second notch or notch R2 pressed from a second free end edge. The second free end edge is opposite to the first free end edge. In addition, the first and second recesses R1 and R2 can be arranged to be aligned with the gap or gap between a pair of adjacent items B. One or two of the notches R1 and R2 can be used to grab the carton 90. A user simultaneously clamps the notches R1, R2, or clamps one of the first and second notches R1, R2, together with the tongue 70 being bent out of the plane of the top plate 20, A handle hole is created to hold the carton.

Each end of the green sheet 10 is provided with an end holding structure, which is used to prevent the contents of the carton 90 from falling out of the carton 90 when the green sheet 10 is assembled into the carton 90.

Each of the end holding structures includes an anchor portion 30a, 30b, 40a, 40b hinged to the adjacent side panel 16, 24 along a folding line 33a, 33b, 47a, 47b. Each end holding structure further includes a web portion 32a, 32b, 38a, 38b hinged to the anchor portion 30a, 30b, 40a, 40b along a folding line 35a, 35b, 45a, 45b. Each of the web portions 32a, 32b, 38a, and 38b is hinged to the top plate piece 20 by a gusset piece 34a, 34b, 36a, 36b. In addition, each of the web portions 32a, 32b, 38a, 38b is hinged to a corresponding gusset piece 34a, 34b, 36a, 36b by a hinge portion in the form of a folding line 37a, 37b, 43a, 43b . The gusset pieces 34a, 34b, 36a, 36b are hinged to the top plate 20 by a hinge part in the form of a folding line 39a, 39b, 41a, 41b.

An optional aperture A2 can be partly from the top plate 20, partly from the first or second side plates 16, 24 or the second and third corner plates 18, 22, and partly from The end holding structure is press-formed. The aperture A2 defines the folding lines 17, 19, 33a, 35a, 37a, 39a; 17, 19, 33b, 35b, 37b, 39b; 25, 27, 41a, 43a, 45a, 47a; 25, 27, One end point of each of 41b, 43b, 45b, and 47b is set at one vertex of the folding lines.

The end holding structures can be bent during the assembling of the carton 90. To form a top joint structure from each end holding structure, first bend the anchor portions 30a, 30b, 40a, 40b by about 180 degrees to form a facing surface with the inner surface of the adjacent side plate pieces 16, 24 relationship. Then, one of the packaged articles B is used to abut the adjacent side plate pieces 16, 24, so that the anchor portions 30a, 30b, 40a, and 40b are kept in the bending position. Thus, the bending of the anchoring portions 30a, 30b, 40a, 40b will cause the web portions 32a, 32b, 38a, 38b to bend outwards around the folding lines 35a, 35b, 45a, 45b, respectively, so that the web The plate portions 32a, 32b, 38a, and 38b extend outward from the fold lines 35a, 35b, 45a, and 45b along the side wall of a packaged article B, and urge them to bend around the packaged article B, thus Extend from the fold lines 35a, 35b, 45a, 45b toward the top panel 20 which is hinged to it by one of the gusset panels 34a, 34b, 36a, 36b, respectively. The top joint structure thus completed is the one shown in FIG. 3, which shows that each of the structures is tightly joined to the top of an outermost article B.

Turning to the manufacture of the carton 90 shown in Figure 3, the carton 90 can be formed by a series of sequential bending operations on a linear machine, so that the manufacture of the carton 90 can be completed without turning or overturning. . The bending process is not limited to those described later, and can be modified according to specific manufacturing requirements.

First gather a group of items B; in the embodiment shown in Figure 3, four items are arranged in a 2 x 2 array. Then, the top plate 20 of the green sheet 10 is placed on the group of articles B to become a top wall 20 of the carton 90.

With respect to the top panel 20, the second and third corner panels 18, 22 are bent around the fold lines 19, 25 to the upper part or near the shoulder of the adjacent article B.

With respect to the top plate 20, the first and second side plates 16, 24 are respectively bent around the folding lines 17, 27 to the sides of the group of articles B opposite to each other, so that the The first and second side wall panels 16, 24 of the carton 90 are formed nearby.

With respect to the top plate piece 20, while bending the first and second side plate pieces 16, 24 to form the aforementioned top joining structures, the anchoring portions 30a, 30b, 40a, and 40b can be bent to The corresponding one of the first and second side plates 16 and 24 forms a veneer relationship.

Alternatively, the carton 90 can be assembled into a tubular form first, and then the top joint structure can be formed. The anchoring portions 30a, 30b, 40a, 40b can be tucked between the corresponding one of the first and second side plates 16, 24 to which they are hinged and an adjacent article B.

With respect to the corresponding one of the first and second side panels 16, 24, the first and fourth corner panels 14, 26 are respectively bent around the folding lines 15, 29 to the heel of the adjacent article B Near the part or lower part.

Before bending the first and fourth corner plate pieces 14, 26 from the corresponding one of the first and second side plate pieces 16, 24, the first heel tongue can be firstly rotated around the fold line 55 The piece 54 is bent out of the plane of the first and fourth corner plate pieces 14, 26.

In some embodiments, the way to achieve this is to bend the first and second floor panels 12, 28 outwards, so that the first heel tongues 54 extend inwardly below the group of items, so that Join one of the items B, and then bend the first and second bottom plates 12, 28 in the opposite direction to below the bottom of the group of items.

Then, bend the second bottom plate 28 around the fold line 31 to abut the bottom of the group of items B. Next, bend the first bottom plate 12 around the fold line 13 to form at least a partial overlap relationship with the second bottom plate 28; in this way, the first heel tongues can be Each piece in 54 is made to engage with a bottom of a corresponding article B.

The first and second base plates 12 and 28 are fixed together. Then, one of the male tongue pieces M is displaced inward from the plane of the first bottom plate piece 12. In this way, each of the female tongue pieces F will be prompted to move inwardly, thereby creating a corresponding opening in the second bottom plate piece 28. When the male tongue pieces M are accommodated in a corresponding one of the openings, the first and second bottom plate pieces 12 and 28 are locked together. Thus, a tubular structure surrounding the group of items B is formed.

The one shown in Figure 3 is the set of cartons 90. Figures 4 and 5 are enlarged views of one of the folding structures FS and the butt structures N3 in the erect carton 90.

The second heel tongues 50a, 50b, the third heel tongues 52a/56a, and the fourth heel tongues 52b/56b are bent outward to the outside of the article B, and the second heel tongue The pieces 50a, 50b, the third heel tongues 52a/56a, and the fourth heel tongues 52b/56b are used to protect the lower part of the article B, especially but not limited to the article B being exposed from the article receiving hole Part of.

The cut line 173 may include extension portions 173 a and 173 b extending from the corresponding finger guard 170 and substantially extending from the folding line 171. Each of the extension portions 173a, 173b can be a "J" or "C"-shaped cut as the end point. In addition, the extension portions 173a, 173b can be provided with a pressure relief device, so as to control or guide the load force when the handle H is used. This can alleviate the tearing and spreading of the top plate 120 when the handle is used.

The blank 110 may include at least one deformed or bent structure FS. The green sheet 110 shown includes several bending structures FS, and can optionally include four bending structures FS. Each bending structure FS forms a deformed corner area of the carton 190, and can optionally form a lower or bottom corner area. The bending structure FS includes a configuration composed of several folding lines, and is suitable for eliminating or reducing the sharpness and/or rigidity of a corner or edge of the carton 190. This can be helpful when transporting or carrying the carton 190 in a carrying bag, especially but not limited to carrying bags made of plastic, paper or similar sheets. The bending structure FS can prevent or reduce the possibility that the carton 190 will perforate, tear, or otherwise puncture or damage the material forming the carrying bag. It should be understood that if the carrying bag has any puncture holes, its load capacity may be reduced; once it is reduced, the tear may spread. This may cause the carrying bag to fail, causing the carton 190 or other items placed in the bag to accidentally fall out, thereby causing the possibility of damage.

The structure of each bending structure FS is substantially the same, so only the bending structure FS provided on the second side plate 124 and the bending structure FS shown in FIG. 7 will be described below.

The bending structure FS includes pressure release tongues 160 and 166 formed from the second side plate 124 and the fourth corner plate 126.

The pressure release tongue pieces 160 and 166 are arranged between a longitudinal or free end edge E1 of the blank piece 110 and an adjacent heel joint structure N4.

The bending structure FS enables a part of the second side plate 124 (and the second corner plate 126 if provided) to bend or deform around an outermost end adjacent to the article B, causing the Part of the free edge is closer to the outermost article B. This reduces the rigidity of the outside or end area of the part, and thus it is easy to deform. In this way, during the loading or carrying of a carrying bag, the possibility of puncturing the wall of the carrying bag or causing other damages by the lower corner of the carton 190 loaded therein is reduced. Therefore, the "double bagging" approach can also be reduced, that is, a first carrying bag is put into a second carrying bag, in order to produce a stronger two-layer carrying bag.

The blank 110 includes at least one article joining structure N1, N2, N3, N4, N5, N6 for joining with a heel, end or lower part of an article B. The green sheet 110 shown in FIG. 8 includes six butt structures N1, N2, N3, N4, N5, and N6 each for joining a corresponding article B. The green sheet 110 includes four outer heel structures N1, N3, N4, N6 and two centered heel structures N2, N5.
