On the other hand, the packaging reinforcing arrangement 20 comprises two reinforcing walls 21 which are integrally extended from two side edges of the bottom wall 12 to the two side walls 16 respectively and are supported within the receiving cavity 17 at a position that a front reinforcing edge 211 and a rear reinforcing edge 212 of each of the reinforcing walls 21 are biasing against inner surfaces of the front and rear walls 14, 15 of the container body 10 for effectively resisting an external impact force exerted from the front and rear walls 14, 15 of the container body 10 to the bottles 70, such that the two reinforcing walls 21 substantially enhance a structural strength of a bottom portion of the container body 10 and prevent collapse of the carrying container.

According to the preferred embodiment of the present invention, the carrying container is made of die cut sheet material which is preferably embodied as a thin and flat sheet material having a semi-rigid material strength. For example, the die cut sheet material can be a fiberboard, a thin plastic sheet or a thin metal sheet, which can be punched, perforated, scored, trimmed and folded easily.

The front wall 14 has a plurality of front display openings 141 spacedly formed thereon for communicating an exterior of the container body 10 with the receiving cavity 17, wherein the front wall 14 forms as a flat and rectangular front panel folded from the sheet material. On the other hand, the rear wall 15 has a plurality of rear display openings 151 spacedly formed thereon for communicating an exterior of the container body 10 with the receiving cavity 17. Similar to the front wall 14, the rear wall 15 is embodied as a flat and rectangular rear panel folded from the same sheet material as mentioned above. Moreover, each of the front display openings 141 is aligned with the corresponding rear display opening 151 such that a user is able to observe the bottles 70 from either the front display openings 141 or the rear display openings 151.

In order to enhance the displaying function of the rear openings 151, each of the rear display openings 151 is shaped and sized to correspond with the bottles stored by the corresponding rear display opening 151. Each of the rear displaying openings 151 is formed by cutting the rear panel along the peripheral edges thereof to form a corresponding number of rear partitioning flaps 152 integrally and foldably extended from a rear hinge portion 153 of the corresponding peripheral edge which is not being cut. In other words, the rear wall 15 further comprises a plurality of rear partitioning flaps 152 integrally and foldably extended from rear hinge portions 153 of the peripheral edges of the rear openings 151 respectively, wherein each of the rear partitioning flaps 152 is adapted to fold inwardly into the receiving compartment 17 to divide the receiving compartment 17 into a corresponding number of storage partitions between each two rear partitioning flaps 152.

Similarly, each of the front displaying openings 141 is formed by cutting the front panel along the peripheral edges thereof to form a corresponding number of front partitioning flaps 142 integrally and foldably extended from a front hinge portion 143 of the corresponding peripheral edge which is not being cut. In other words, the front wall 14 further comprises a plurality of front partitioning flaps 142 integrally and foldably extended from front hinge portions 143 of the peripheral edges of the front openings 141 respectively, wherein each of the front partitioning flaps 142 is adapted to inwardly fold into the receiving compartment 17 to overlap with the rear partitioning flaps 152 for strengthening portioning between each two storage partitions and to enhance protection for each storage partition from external impact. In other words, the front and rear partitioning flaps 142, 152 constitute a double wall structure for dividing the storage partitions by overlapping the front and rear partitioning flaps 142, 152.

Thus, the front panel and the rear panel are preferably flat, rectangular or irregular shaped. There are preferably used as panels to shield and enclose the product in between. They preferably have a few hinged cut out (for forming the front and the rear hinge portion 143, 153) to be pushed into the body of the carrying container and function as the partitions for cushion or a few cut out pieces from the panels to place inside of the carrying container function as the individual partition for cushion.

The bottom wall 12 comprises a bottom panel which is preferably a flat part of the carrying container. It is preferably used to support the product weight. The bottom panel is preferably surrounded by the front wall 14, rear wall 15, and the two side walls 16.

According to the preferred embodiment of the present invention, each of the sidewalls 16 comprises a first and a second side panel 161, 162 integrally and foldably extended from the front wall 14 and the rear wall 15 respectively, wherein the first side panel 161 is arranged to detachably engage with the second side panel 162 for forming a rigid double wall structure for each of the sidewalls 16. More specifically, each of the first side panels 161 comprises a locking flap 1611 foldably provided at an outer side edge portion thereof, whereas each of the second side panels 162 further has a through locking slot 1621 formed thereon to align with the corresponding locking flap 1611 which is then adapted to detachably engage with that locking slot 1621 for detachably engaging the first side panel 161 with the second side panel 162.

Referring to FIG. 4 of the drawings, it is important to mention that each of the second side panels 162 further has two holding silts 1622 extended from two ends of the locking slots 1621, whereas for each of the first side panels 161, the locking flap 1611 has a main locking portion 1612 and a contracted portion 1613, having a width smaller than a width of the main locking portion 1612, integrally extended from the front wall 14 to define two L-shaped locking shoulders 1614 between the main locking portion 1612 and the contracted portion 1613 at two sides thereof respectively, wherein the L-shaped locking shoulders 1614 is arranged to fittedly and detachably engage with the two holding slits 1622 respectively when the locking flap 1611 is detachably engaged with the corresponding locking slot 1621.

In other words, one of the first side panels 161 can be embodied as a front right side panel which engages with the second side panel 162 embodied as a rear right side panel by engaging the front right side locking flap 1611 lock into the rear right locking slot 1621 and blocking by the rear right holding slits 1622. Similarly, one of the first side panels 161 can be embodied as a front left side panel that engages with another second side panel 162 embodied as a rear left side panel by letting the front left side locking flap 1611 lock into the corresponding rear left locking slot 1621 and blocking by the corresponding rear left holding slits 1622.

Furthermore, the first and the second side panels 161, 162 further have a first and a second interlocking slot 1615, 1623 formed on the first and the second side panels 161, 162 respectively to define first and second interlocking edges 1616, 1624 as side edges of the first and the second interlocking slots 1615, 1623 respectively, wherein when the first and the second side panels 161, 162 are engaged with each other, the first and the second interlocking slot 1615, 1623 are interlocked with each other to further enhance a secure engagement between the first and the second side panels 161, 162.

It is worth mentioning that each of the first side panel 161 and the second side panel 162 has a slanted bottom edge 1617, 1625 such that when the first side panel 161 is detachable engaged with the second side panel 162, the slanted bottom edges 1617, 1625 are arranged to overlap with an outer surface of the corresponding reinforcing wall 21. Each of the side walls 16 further comprises a first and a second triangular panels 163, 164, wherein the first triangular panel is integrally extended between the slanted bottom edge 1617 of the first side panel 161 to the front reinforcing edge 211 of the corresponding reinforcing wall 21, and that the second triangular panels 164 is integrally extended between the slanted bottom edge 1625 of the second side panel 162 to the rear reinforcing edge 212 of the corresponding reinforcing wall 21 at the corresponding side wall 16.

Thus, in order words, the first triangular panel 163 is embodied as a front right triangle piece which is a thin piece of the sheet material for integrally connecting the first side panel 161 with the reinforcing wall 21. Similarly, the second triangular panel 164 is embodied as a rear right triangle piece for integrally connecting between the second side panel 162 and the reinforcing wall 21.

Referring to FIGS. 1 to 5 of the drawings, the carrying container further comprises a handling arrangement 30 extended from the top wall 13 of the container body 10 to facilitate easy carrying of the carrying container. More specifically, the top wall 13 of the container body 10 comprises a first and a second top panel 131, 132 integrally extended from a top edge of the front and the rear wall 14, 15 respectively, wherein the handling arrangement 30 comprises a first and a second holding flaps 31, 32 integrally extended from the top edges of the first and the second top panels 131, 132 respectively for normally enclosing the receiving cavity 17 from the top side of the container body 10, and allowing a user of the present invention to grip on the holding flaps 31, 32 so as to carry the carrying container in a convenient manner.

The handling arrangement 30 further has a plurality of handling slots 33 formed on the first and the second holding flaps 31, 32 respectively for allowing a user to grip thereon through the handling slots 33. Referring to FIG. 5 of the drawings, each of the handling slots 33 is aligned with each other and is elongated in shape for fitting a width of the user's hand. In order to optimize the carrying comfort of the present invention, the handling arrangement 30 further comprises two holder pads 34 integrally extended from top edges of the handling slots 33 of the first and second holding flaps 31, 32, wherein the holder pads 34 are arranged to extend through the handling slots 33 to partially overlap with an outer surface of the second handing flap 32 so as to embed the top edges of both of the handling slots 33, in such a manner that when a user is carrying the carrying container by the first and the second holding flaps 31, 32, the user's hand is adapted to grip on the holding flaps 31, 32 that the holding flaps 31, 32 are cushioned by the holder pads 34. Therefore, the user's comfort is maximized when he or she is holding the carrying container with the help of the handling arrangement 30. In other words, the holder pads 34 are integrally extended from the top edges of the handling slots 33 of the first and second holding flaps 31 to foldably overlap with the second holding flap 32 with the two holder pads 34 and the first holding flap 31 so as to form a quad-wall structure to ensure the receiving cavity 17 being enclosed when the carrying container is being carried. It is worth to mention that the first and the second holding flaps 31, 32 and the holder pads 34 overlappingly form the handle portion of the carrying container to increase the thickness and the strength thereof and to gain the holding surfaces stronger. Therefore, the handle structure is easier for the user to handle and reduces the uncomfortable cutting feeling on the fingers. It is worth to mention that the two holder pads 34 are integrally extended from the top edges of the handling slots 33 of the first and second holding flaps 31, 32 such that when the holder pads 34 are folded to overlap with the second holding flap 32 through the handling slot 33 thereof, the handle of the container body 10 forms a quad-wall structure that is stronger to avoid breakage and thicker to save the cutting feeling.

Referring to FIG. 1 to FIG. 3 of the drawings, the packaging reinforcing arrangement 20 further comprises a weight support assembly 22 extended from the top wall 13 of the container body 10 to facilitate even distribution of loading along the container body 10 via the bottom wall 12, the top wall 13, the front wall 14, the rear wall 15, and the two side walls 16 so as to allow effective withstanding of loading by the container body 10. The weight support assembly 22 comprises a first and a second hanging flaps 221, 222 integrally and foldably extended from top edges of the side walls 16 respectively, and a plurality of hanging ears 223, 224 integrally and outwardly extended from two sides of each of the holding flaps 31, 32 to define a corresponding number of V-shaped notches 225 on each of the holding flaps 31, 32.

According to the preferred embodiment of the present invention, each of the first and the second hanging flaps 221, 222 comprises two flap panels 2211, 2221 integrally and upwardly extended from top edges of each of the first and the second side panels 161, 162 of the corresponding side wall 16 to substantially align with each other and engage with the first and the second hanging ears 223, 224. More specifically, each of the flap panels 2211, 2221 has an elongated weight loading slot 2212, 2222 formed thereon, wherein the flap panels 2211, 2221 are folded in such manner that top peripheral edges of the weight loading slots 2212, 2222 are arranged to engage with the corresponding supporting notches 225 so as to withstand the loading from the products carried within the receiving cavity 17.

The hanging ears 223, 224 are preferably an irregular shaped, rounded flat piece extended and enlarged outwardly though the supporting notches 225 of the hanging flaps 221, 222. Its is preferable that the two right top hanging flaps 221 are hanging together on the two right side hanging ears 223 and two left top hanging flaps 222 are hanging together on the two left side hanging ears 224.

The loading (i.e. the weight from the objects—the bottles 70) is preferably carried evenly by tucking a pair of right side hanging ears 223 into the pair of right side supporting notch 225 on the right side hanging flap 221 and by tucking a pair of left side hanging ear 224 into the pair of left supporting notch 225 on the left side hanging flap 222. The durability of the hanging ears 223, 224 is preferably strengthened by extending the ear size outwardly and spaced away form the corresponding supporting notch 225 to avoid the stress concentration caused by the heavy load on the holding flaps 31, 32.

It is worth mentioning that a distance between each of the supporting notches 225 and the corresponding hanging ear 223 (224) could be optimally maximized so as to maximize the loading to which the carrying container is capable of withstanding without causing unwanted breakage of the hanging ears 223, 224. The purpose of the extension of the hanging ears 223, 224 outwardly is to space away the supporting notch 225 from the handling slot 33 to avoid breakage and tearing of the first and second holding flaps 31, 32. Usually, it causes by stress concentration on the supporting notch 225 and extended to the handling slot 33. In the mean time, the handling slot 33 can be widened to accept larger hand. Moreover, since the supporting notches 225 are interlocked with the weight loading slots 2212, 2222, the heavier the loading, the tighter the interlocking between the supporting notches 225 and the weight loading slots 2212, 2222. Preferably, a distance between the two pairs of the supporting notches 225 is the same as a distance between the two side walls 16 of the container body 10, i.e. the width of the container body 10.

It is worth to mention that since the bottom wall 12 is arranged to support the weight of the bottles 70 as the downward loading force, the front and rear walls 14, 15 are adapted to evenly distribute the downward loading force by integrally extending the front and rear walls 14, 15 from the bottom wall 12. In addition, once the first and second side panels 161, 162 are locked with each other, the first and second side panels 161, 162 not only evenly distributes the downward loading force from the bottom wall 12 to rigidly support the bottles 70 but also forms a rigid double wall structure for each of the sidewalls 16 of the container body 10 to retain the container body 10 in rigid box-shape structure. Furthermore, when the container body 10 is carried by the user via the handling arrangement 30, the upward carrying force can be evenly distributed through the container body 10. It is because when the user lifts up the container body 10, the upward carrying force is applied at the first and second holding flaps 31, 32 to the front and rear walls 14, 15 through the first and second top panels 131, 132 respectively. The upward carrying force is also evenly distributed to the sidewalls 16 through the weight support assembly 22. Therefore, having the above mentioned interlocking one-piece structure, the container body 10 is adapted to support the bottles 70 without distorting the loading structure of the carrying container. In other words, the present invention provides a 3-dimensional reinforcement to evenly distribute the weight of the bottles 70 through X, Y, and Z axes of the container body 10 through the bottom wall 12, the front and rear walls 14, 15, the sidewalls 16, and the top wall 13.

In operation, use a multiple cavity steel rule die board, to die cut a sheet material with a steel rule die with indentation lines, perforation lines, flanges, cutting lines, and punched holes according to the design of this carrying container.

The cut off from the panels for the four-bottle container body 10C are removed to form the partition by engaging the partitions together and place them between the bottles. In the four-bottle container body 10C, however, each bottle is positioned within the receiving cavity as one of a 2×2 array so that the present invention can easily be adjusted to be utilized in a wide variety of circumstances. As shown in FIG. 10, the six-bottle container body 10D (2×3) is especially used to carry 6 bottles of champagne with the weight up to 10 lb and above, in which each bottle of champagne is approximately 3.75 lb. It is worth to mention that for the six-bottle container body 10D, 3 pieces of partitions are cut out from the front panel and the rear panel to form the cavity partition. According to the 72 hours of the hanging performance test at 68° F. and 72 RH (relative humidity), all the prototype testing sample (10, 10A, 10B, 10C, 10D) pass the testing without any failure which proves the present invention is a functional design. In addition, the present invention not only provides the function and strength of the structural principles of the carrying container but also demonstrates how to maximize the usage of the material by minimizing the material waste and eliminate the unnecessary gluing operation.
