The details of the structure and function of the invention are not to be construed as limiting the scope of the invention, but are to be construed as the basis of the scope of the patent application, and to teach the skilled person to use the representative basis of the invention.

The first embodiment of the blank 1 for forming a carton 100 (shown in detail in Fig. 8) is shown in Fig. 1. The blank 1 comprises a plurality of sheets which are formed to form a reinforcing beam structure constructed in accordance with the first embodiment of the present invention. The advantage of such a beam structure is that it is easy to assemble, as long as a single folding operation can be completed, and it includes a reinforcing position that can be folded into the beam structure by a simple second folding operation to prevent its collapse.

The blank 1 comprises an outer bottom plate 2, a first side plate 4, a top plate 6, a second side plate 8, and an inner bottom plate 10 hinged by a folding line 44, 42, 40, 38, 36, respectively, in a linear series. And a second beam side panel 24. The panels are configured to allow the blank 1 to wrap around a group of articles A such that the inner and outer panels 10, 2 are at least partially overlapped to provide a tubular structure surrounding the articles A while the beam structure (described in detail later) separates some of the selected items A.

The inner bottom panel 10 includes sheets that are formed to form two beam structures 29 (one of which is shown in detail in FIG. 8 in an assembled state), each of the sheets including being disposed within the inner bottom panel 10 and along the fold line 30. A hinged first beam side panel 20. Next, the first beam side panel 20 is hinged along its own opposite edge by another fold line 32 to the beam top panel 22 disposed within the second beam side panel 24. The fold line 32 is preferably formed by a curved cut line defining a flange extending outwardly from the first beam side panel 20 with the end of the flange offset from the proximal edge of the first beam side panel 20, Thus, a plurality of weakened joints are provided between the first beam side panel 20 and the beam top panel 22 that are hinged to each other. The beam top panel 22 is then hinged to the second beam side panel 22 by fold lines 34 along its own opposing edges.

The distances at which the fold lines 34, 36, respectively for articulating the beam top panel 22 and the inner bottom panel 10 to the second beam side panel 22, are substantially offset from each other are substantially equal to the length of the first beam side panel 20. Such a configuration allows the first and second beam side plates 20, 24 which are perpendicular to the inner bottom plate 10 to be bent at right angles in the case of simultaneous bending (as shown in FIG. 8), and preferably in a square shape. The beam structure 29 is completed.

The fold line 30 that hinges the first beam side panel 20 to the inner bottom panel 10 is interrupted by a cutting line 31 that extends partially into the first beam side panel 20 to form a catch 26. Therefore, when the first side panel 20 is assembled into a use state, the latch 26 is inserted into an opening in the inner bottom panel 10 which is vacated by the first beam side panel 20 (as shown in FIG. 7). The dice 26 has a substantially uniform width with a corner rounded to serve as a guide for the abutment edge during the folding process described later.

The second configuration for each of the panels for forming the beam structure 29 on the inner bottom panel 10 is the same as the one described above, and the second beam side panel 24 is shared by the two beam structures along the inner bottom panel 10 and the straight line. The full width extension of the longitudinal axis of the series of plates.

The outer bottom plate 2 includes a plurality of plates for forming a reinforcing arrangement 50 for reinforcing the corresponding two beam structures 29, each of the reinforcing arrangements 50 including a piece disposed in the outer bottom plate 2 and hinged to the outer portion by a folding line 66. The main cymbal 51 of the bottom plate. The opposite sides of the main flap 51 adjacent to the fold line 66 are hinged to the side of the first and second side tabs 52, 54 by the first and second fold lines 60, 61, respectively. The folding line 66 that hinges the main flap 51 to the outer bottom panel 2 is designed to be substantially perpendicular to the end of the outer bottom panel 2 so that the main flap 51 and the beam structure 29 are folded into the carton 100 in a manner to be described later. The beam side panels 20, 24 remain vertical.

Each of the first side tabs 52 extends from the main jaw 51 toward the first side panel 4 and has a uniform width from the head to the tail. However, the terminal end of the first side tab 52 that is adjacent to the fold line 66 is deflected inwardly so that each of the first side tabs 52 is on the outer bottom plate 2 by an outer edge defined by the cutting line 63. Intersects with a terminal of the fold line 66. The other end of each of the first side tabs 52 is slightly offset from the corresponding end of the main flap 51 such that the length of the first side tab 52 is slightly shorter than the main flap 51.

The other side of the main flap 51 is provided with a second side tab 54 extending away from the first side panel 4. The widths of the second side tabs 54 are uniform from head to tail. In addition, the two ends of the second side tab 54 are offset from the corresponding abutment ends of the main flap 51 such that their length is shorter than the first side tab 52 and relative to the folding of the main flap 51 to the outer bottom panel 2 Line 66 also deviated.

In order to facilitate the alignment between the reinforcing arrangement 50 and the beam structure 29, the fastening portions 90/91, 96/99 are preferably provided in the vicinity of the inner bottom plate 10 and the outer bottom plate 2. The locking arrangement 90/91, 96/99 preferably includes a punch-lock structure, that is, an aperture 91, 99 formed in the inner bottom plate 10 and an engaging tongue 90 formed on the outer bottom plate, 96 is composed. In the illustrated embodiment, two apertures 91, 99 and two corresponding engagement tabs 90, 96 are provided. When the bottom and outer bottom plates 10, 2 are overlapped in the manner described later, the engaging tongues 90, 96 can be poked from the outer bottom plate 2, and then bent through the holes 91, 99, thereby making the bottom and The outer bottom plates 10, 2 are joined together.

In particular, the first engagement tab 90 is defined by the cut line 94 and is hinged to the outer bottom panel 2 along the fold line 95. The first engagement tabs 90 are provided with a plurality of detents along opposite sides of the opposite side of the fold line 95. When the first engaging tabs 90 pass through the corresponding apertures 91 of the inner bottom panel 10, the latches are warped and occupy a position substantially against the inner surface of the inner bottom panel 10 upon insertion. The first engagement tab 90 is thus prevented from being detached from the aperture 91. The first aperture 91 is created when the first aperture tab defined by the cutting line 92 on the inner bottom panel 10 is bent out of the inner bottom panel 10 in response to the inward bending force experienced by the first engagement tab 90.

The second engagement tab 96 is defined by the cut line 97 and hinged to the outer bottom panel 2 along the fold line 98. The second engagement tab 96 is provided with a catch. The forceps are formed on one side thereof and warp when the second engagement tab 96 is inserted into the corresponding second aperture 99. Upon insertion, the forceps abut against portions of the inner surface of the inner bottom panel 10 to prevent the second engagement tabs 96 from coming out of the second apertures 99. The second aperture 96 is created when the second aperture tab defined by the cutting line 89 on the inner bottom panel 10 is bent out of the inner bottom panel 10 in response to the inward bending force experienced by the second engagement tab 96. In order to increase the fixing force between the inner and outer bottom plates 10, 2, the second engaging tongue 96 may be provided with more than one set of tweezers.

The top panel 6 includes, for each article A that is to be disposed adjacent to the corresponding side panels 4, 8, each includes a dice 71 extending from one side thereof for use with the article, for example, on each side as shown Two dice 71. The dice 71 extend from the edge of the top plate 6 into the corresponding side plates 4, 8 on the blank 1, and are poked from the side plates 4, 8 by a carton assembly process which will be described later. The dice 71 are defined by a cutting line 70 that interrupts the folding lines 42, 40 that respectively hinge the top panel 6 to the first and second side panels 4, 8. The short portions 75 of the cutting lines 70 continue over the fold lines 42, 40 and extend a short distance within the range of the top plate 6. A cutting line 74 extending from the top plate 6 and extending into the corresponding first and second side plates 4, 8 extends from two points on each of the cutting lines 70. An upper flexible tab 72 is defined between the cutting lines 74.

The first and second side panels 4, 8 each include a cutting line 78, 80 that can be used for each of the detents 71 to form a tab 76 at the edges of the side panels 4, 8 adjacent the inner or outer bottom panels 2, 10, respectively. . The cutting lines 78, 80, 81 include a linear portion 80 that is coaxial with and interrupts the fold lines 44, 38, while the fold lines 44, 38 hinge the first and second side panels 4, 8 to the inner and outer bottom plates 2, respectively. , 10. The short terminal cutting line 81 and the mid-point cutting line 78 each extend perpendicularly to the linear portion 80 toward the top plate 6, and a lower flexible tongue 76 is formed therebetween (on both sides of the mid-point cutting line 78). .

A preferred method of assembling the carton 100 will now be described (the ones shown in Figures 2 through 8 are various stages of assembly).

The blank 1 is first placed on top of a group of articles A such that the top plate 6 is placed over the top surface of the articles A. Next, the first and second side panels 4, 8 are bent downward around the sides of the set of articles A. The upper portion of the article A is provided with a flange, and a portion of the flanges is located below the dice 71 of the top plate 6 and passes through a portion where the dice 71 are poked out from the first and second side plates 4, 8. Orifice. When the first and second side panels 4, 8 are urged against the outer surface of the adjacent article A, the upper flexible tongue 72 can be deformed as necessary to fit the circular outer surface of the upper portion of the adjacent article A.

Thereafter, as shown in FIG. 2, when the first and second beam side plates 20, 24 of the carton 100 are bent inwardly at positions perpendicular to the inner bottom plate 10 to form the respective beam structures 29, the inner bottom plate 10 is assembled. That is, it is bent to contact a part of the lower side of the group of articles. When the beam structure 29 is placed between the adjacent items A of the set, it is assembled to a degree sufficient to be located between the items A. Next, according to the method shown in FIG. 3, the outer bottom plate 2 is bent into contact with a portion of the bottom side of the group of articles A and a portion of the inner bottom plate 10, thereby producing a tubular structure as shown in FIG. . When the first and second side panels 4, 8 are urged against the outer surface of the adjacent article A, the lower flexible tongues 76 of the first and second side panels 4, 8 may be deformed as necessary to withstand the interior thereof The circular outer surface of the adjacent article A is matched.

The beam structure 29 is formed from an end region of the inner bottom plate 10. Once assembled, this end region of the inner bottom panel 10 will be entirely located between the selected items A. The outer surfaces of the articles help to further enhance the fastness of the beam structure 29 by resisting the beam structure 29 against collapse.

The locking arrangement 90/91, 96/99 secures the inner and outer bottom plates 10, 2 in close proximity to the article, thereby forming a combined bottom plate of the carton. The locking arrangement 90/91, 96/99 not only has the function of interlocking the inner and outer bottom plates 10, 2, but also ensures that the position of the reinforcing arrangement 50 is stable in terms of the assembled beam structure 29, thereby contributing to The reinforcing arrangement 50 remains engaged with the beam structure 29. In use, the engagement of the reinforcing arrangement 50 with the beam structure 29 prevents the inner and outer bottom plates 2, 10 from rotating about the locking arrangement 90/91, 96/99, so in this respect, the reinforcing arrangement 50 pairs are locked. Configurations 90/91, 96/99 are also helpful.

The foregoing folding operation sequence will cause the reinforcing arrangement 50 to be longitudinally aligned below the assembled beam structure 29 such that the main jaws 51 of each reinforcing arrangement 50 can be hinged about the fold line 66 that is hinged to the outer bottom panel 2 from the corresponding The beam structure 29 is bent inwardly (shown in detail in Figures 5-7) through the apertures in the inner bottom panel 10 that are vacated and formed by the assembly of the first beam side panels 20. Each of the main flaps 51 can be used to reinforce the side edges of the second side tabs 54 to which the reinforcing members 50 are hinged, substantially in alignment with the fold lines 30 that hinge a beam side panel 20 to the inner bottom panel 10. Therefore, the inward bending of each main flap 51 is countered by the abutment of the second side flap 54 with the inner bottom panel 10, and the mating of the latch 26 with portions of the main flap 51.

In order to articulate the main jaw 51 into the beam structure 29, the main jaw 51 must undergo some warping, which can be produced if the material of the reinforcing arrangement 50 is flexible. When the main flap 51 is hinged into the beam structure 29, the rounded corner of the latch 26 can be used as a wedge to gradually increase the warpage of the main flap 51, so that the warp of the main flap 51 is Help. When the main flap 51 is pushed into the beam structure 29, thereby causing the second side tab 54 to be bent outwardly from the plane of the main flap 51, the second side tab 54 is hinged to the fold line 61 of the main flap 51. That is, flexion. When the main flap 51 is bent into the inside of the carton 100, the outer surface of the second side flap 54 will slide over the leading edge of the latch 26 until the second side tab 54 passes the catch 26 as a whole. The offset between the fold line 66 and the proximal end of the second side tab 54 allows for some degree of clearance above the resulting upper surface of the latch 54 so that the second side tab 54 can be passed around the main flap The side of the 51 is bent. Similarly, the offset between the other end of the second side tab 54 and the proximal edge of the main flap 51 helps the second side flap 54 to be bent about the fold line 61 relative to the main flap 51. At this point, the natural biasing of the material used to form the reinforcing arrangement 50 causes the second side tab 54 to bend back toward the plane of the primary jaw 51 until it abuts the first beam side panel 20. This abutting or frictional contact of the second side tab 54 with the first beam side panel 20 prevents the beam structure 29 from collapsing or prevents the beam panels 20, 22, 24 from bending back into the plane of the inner bottom panel 10. The free upper edge of the main flap 51 should also be brought into contact with the lower surface of the beam top panel 22, which also prevents the beam structure 29 from collapsing. At this time, as shown in detail in Fig. 7 (from the bottom up) and Fig. 8 (from the top down), the second side tab 54 is against the upper surface of the latch 26, and this docking prevents the main tab. 51 is bent out of the beam structure 29.

While the second side tongue 54 is bent, the first side tongue 52 is also urged against the lowermost surface of the article A on which the portion is placed. At that time, the fold line along which the first side tab 52 is hinged to the main flap 51 will flex in response, causing the first side tab 52 to be bent out of the plane of the main flap 51, and the first side The outer surface of the tongue 52 slides over the outer surface of the lower portion of the article A. Before the main cymbal sheet 51 is bent into the inside of the carton 100, because the yaw portion of the end of the first side tongue 52 defines the degree of bending of the first side tongue 52, the side tongue 52 and the main cymbal are not required. The sheet 51 remains substantially vertical, so this process is helpful.

Therefore, when the main cymbals 51 are bent to be perpendicular to the inner bottom plate 10, the second side tongues 54 of the main cymbals 51 are in surface contact with the first beam side plates 20 of the corresponding beam structures 29. Or butt, and the lower edge of the second side flap 54 is against the upper surface of the latch 26. These abutments of the reinforcing arrangement 50 on the corresponding beam structure 29 prevent the primary jaw 51 from bending back into the plane of the outer floor 2, thereby maintaining a vertical relationship with the outer floor 2. The upper edge of the main flap 51 is preferably placed against the lower surface of the beam top panel 22, thereby preventing the main flap 51 from being bent back to the plane of the outer bottom panel 2. The docking of the opposing side edges (i.e., the first side tabs 52) of the main flap 52 with the lower portion of the adjacent article A (see Figure 8) facilitates this. Since the first beam side panel 20 is hinged to the second beam side panel 24 via the beam top panel 22, such abutting also prevents the beam top panel 22 and the second beam side panel 24 from bending back into the plane of the inner bottom panel 10, thereby also making the beam structure 29 remains in an assembled state.

If the package of the article has been completely assembled and assembled, the main flap 51 of each reinforcing arrangement 50 forms a bracket between the item on one side and the side of the beam structure 20 on the other side.

Because the first and second beam structures 29 are formed using a common second beam side panel 24, each enhancement enhances the reinforcement of the other. As a result, the second beam side panel 24 and the inner bottom panel 10 are retained even if the reinforcement of the first of the two beam structures 29 fails due to reasons such as damage to the corresponding reinforcement configuration 50 or bending out of the beam structure 29. The vertical relationship still helps to keep the second beam structure in an assembled state.

It should be understood that the advantage of the carton 100 constructed in accordance with this embodiment is that it is easy to manufacture as long as the two folding operations of the beam structure 29 and the insertion reinforcement configuration 50 are combined. Even after the inner and outer bottom plates 10, 2 are in a lapped relationship, the work of folding the reinforcing arrangement 50 into the beam structure can still be achieved. This eliminates the potential drawbacks that may occur in manufacturing when the outer bottom plate 2 is folded into contact with the inner bottom plate 10 while the reinforcing arrangement needs to be properly bent and directly inserted into the beam structure.

Figure 9 shows the final configuration of the completed carton with four items A. For clarity, the items of the carton 100 shown in Figure 9 are indicated by dashed lines to show the relative position of the items to the beam structure 29.

The blank 1 is contemplated to include any number of beam structures 29 and corresponding reinforcing arrangements 50. The blank shown is suitable for storing 2 x 2 arrays of articles and thus acts to separate items in each column from another item in the same column. However, the present invention also contemplates that there may be more beam structures 29 and associated reinforcing configurations 50 to accommodate the desired group size and layout, including separating a list of items from adjacent items in another column. Or separate the item from the adjacent carton wall.

The blank 1 shown is suitable for forming a wrapped carton 100. However, the beam structure of the present invention is contemplated to be applicable to other types of cartons, including, in particular, end-loaded cartons and trays. Depending on the nature of the carton, the carton assembly process will vary. For example, a tray type carton may be more suitable for pre-forming the assembled beam structure prior to loading the item.

It will be appreciated that the present invention can be practiced without departing from the scope thereof, for example, the size and shape of the sheets can be adjusted to accommodate articles of different sizes or shapes.

Different object array configurations or other facts may also differ for the desired beam structure profile. Although in the first embodiment described, the first and second beam side panels 20, 24 and the beam top panel 22 each have substantially equal lengths to produce a beam structure having a square cross section, the side edges of the beam structure are contemplated. For example, it can be longer or shorter than the beam top. As a result, the beam top panel is contemplated such that if the width of the beam structure is matched to the resulting length of the beam roof panel, a section of the beam roof panel can be provided on the inner bottom panel 10 and the second beam side panel 24.

Additionally, the second beam side panels 24 are contemplated as not being shared by two (or all) beam structures 29, each beam structure 29 having its own independent second beam side panel 24.

Each of the directional terms described herein, such as "top", "bottom", "front", "back", "end", "side", "inside", "outside", "upper" and "lower", etc. It is not intended to limit the relevant sheets to this orientation, but only to distinguish the sheets. The reference to the articulator is not to be construed as necessarily limiting the folding line; in fact, the hinge may be constructed of one or more of the following types: short cracks, frangible lines, or fold lines, without departing from the scope of the invention.

The disclosure of the present invention is a preferred embodiment. Any change or modification of the present invention originating from the technical idea of the present invention and being easily inferred by those skilled in the art will not deviate from the scope of patent rights of the present invention.
