Description

Packaging structure

Technical Field

The present invention relates to a packaging structure.

Background

At present, the packaging method for fragile articles such as electronic components is carried in a carton box having a plurality of partitions therein, and the packaging structure is referred to as a honeycomb partition. Specifically, the honeycomb partition board uses a plurality of partition boards to separate different packaging spaces, so as to individually place a plurality of articles in the packaging spaces, thereby avoiding the articles from being damaged due to mutual collision during transportation.

Fig. 1 is a schematic view of a conventional packaging structure, that is, a conventional honeycomb partition, referring to fig. 1. The known packaging structure 9 comprises a box 91, a plurality of transverse partitions 92 and at least two longitudinal partitions 93. Before the object is transported, the packaging structure 9 is assembled. Generally, the transverse partition 92 and the longitudinal partition 93 have a plurality of engaging grooves, so that the transverse partition 92 and the longitudinal partition 93 can be assembled by engaging with each other. Next, the assembled transverse partition 92 and longitudinal partition 93 are placed in the box 91, as shown in fig. 1. Finally, a plurality of articles (e.g., electronic components) to be transported are placed in the packaging space partitioned by the transverse partition 92, so as to achieve the effect of avoiding the articles from colliding with each other.

The longitudinal partition 93 is used to fix the interval width of the transverse partition 92. However, the transverse partition plates 92 and the longitudinal partition plates 93 are assembled only by engaging with each other, and the structures thereof are scattered and weak. Therefore, the combined transverse partition 92 and longitudinal partition 93 may fall off before being placed in the box 91. In addition, when the combined transverse partition plate 92 and the combined longitudinal partition plate 93 are stacked, the clamping groove is more easily torn due to pulling, and the improvement is necessary.

In order to make the technical content of the present invention more comprehensible, preferred embodiments are described below.

Fig. 2 is a schematic view of a packaging structure according to an embodiment of the present invention, fig. 3 is an exploded schematic view of the packaging structure shown in fig. 2, and fig. 4 is a schematic plan view of a body and a side plate of the packaging structure shown in fig. 3, please refer to fig. 2, fig. 3, and fig. 4. The packaging structure 1 of the present embodiment includes two main bodies 10 and four side clamping plates (two upper clamping plates 20 and two lower clamping plates 20 a). The packaging structure 1 of the present embodiment is a paper packaging structure, and the main body 10, the upper clamp plate 20 and the lower clamp plate 20a, which are respectively cut into a plate shape, are plate bodies, as shown in fig. 4. After the two bodies 10 are connected with each other, they can be folded to form a three-dimensional box, as shown in fig. 2 and 3.

The main body 10 includes a main board 11, two cover boards 12 and a side board 13. The motherboard 11 has an upper side 111, a lower side 112, and a first side 113 and a second side 114 connecting the upper side 111 and the lower side 112. In this embodiment, the main board 11 may have a rectangular structure, and the upper side 111 and the lower side 112 are long side edges, and the first side 113 and the second side 114 are short side edges. The cover 12 is connected to the upper side 111 and the lower side 112 of the main board 11, respectively, and the cover 12 is folded back toward the main board 11 to form the bottom and the top of the package structure 1. One side of the side plate 13 is connected to a first side 113 of the main plate 11, and the other side of the side plate 13 is connected to a second side 114 of the main plate 11 of another main body 10. Preferably, the side plate 13 includes a bonding portion 131 at an end of the side plate 13 away from the main plate 11, and the bonding portion 131 can be connected to the second side 114 of the main plate 11 of another main body 10. In other embodiments, the bonding portion 131 may also be disposed on the main board 11 and connected to the side board 13 of another main body 10.

The side plate 13 of the present embodiment includes a plurality of spacing units 132(132a) and is arranged in parallel outwardly from the first side 113, and the spacing units 132(132a) are connected to each other. The spacing unit 132 includes a spacing portion 133 and a clamping portion 134. The partition 133 is connected to the main board 11 or to the adjacent partition unit 132. Taking the spacing unit 132 as an example, the spacing part 133 is connected to the main board 11; taking the spacing unit 132a as an example, the spacing portion 133 is connected to the adjacent spacing unit 132. In addition, the clamping portion 134 is disposed adjacent to the spacing portion 133 to form a structure in which the spacing portions 133 and the clamping portions 134 of the plurality of spacing units 132 are disposed alternately.

The side panel 13 of the present embodiment further includes a first folding line 135, a second folding line 136 and a third folding line 137, which may be pressing lines, and are distributed in parallel on the side panel 13 to form the spacing unit 132 by folding. The first folding line 135 is located at the connection between the partition 133 and the main panel 11 or the adjacent partition unit 132. Also taking the spacing unit 132 as an example, the first folding line 135 is located at the connection position of the spacing part 133 and the main board 11 (i.e. the first side 113); taking the spacing unit 132a as an example, the first folding line 135 is located between the spacing portion 133 and the adjacent spacing unit 132. In addition, the second folding line 136 is located between the spacing portion 133 and the clamping portion 134, and the third folding line 137 is located at a central position of the clamping portion 134. In general, each of the spacing units 132 has a first fold line 135, a second fold line 136 and a third fold line 137 which are parallel to each other and are sequentially arranged outward from the main panel 11.

With the above structure, the side panel 13 can be folded into the partition unit 132 having a plurality of three-dimensional structures, as shown in fig. 5. Fig. 5 is a schematic view of the two bodies shown in fig. 4 bonded together with the side panels folded. The spacer 133 may be folded to be perpendicular to the main panel 11 at the first fold line 135. The clamping portion 134 is folded to be perpendicular to the spacing portion 133 by a second fold line 136 and is parallel to the main plate 11. The clamping portions 134 are folded back by a third fold line 137, so that the adjacent spacing units 132a can be folded again in the same manner, thereby forming a structure in which the clamping portions 134 of the plurality of spacing units 132(132a) are parallel to each other inside the body 10. When packaging articles, a plurality of articles can be placed in the space between the clamping portions 134. In other words, the structure of the clamping portions 134 parallel to each other inside the body 10 can be used as a partition (such as the known transverse partition 92) of the packaging structure 1.

Specifically, the spacing unit 132 is first folded to be perpendicular to the main plate 11 by the first folding line 135, and the clamping portion 134 is then folded to be parallel to the main plate 11 by the second folding line 136. Then, the clamping portion 134 is folded back by the third fold line 137 to form a first engaging unit 134a and a second engaging unit 134b, wherein the first engaging unit 134a is connected to the spacing portion 133 of the corresponding spacing unit 132, and the second engaging unit 134b is connected to the spacing portion 133 of the adjacent spacing unit 132 a. In other words, the clamping portion 134 includes a first engaging unit 134a and a second engaging unit 134b, and the spacing portion 133, the first engaging unit 134a and the second engaging unit 134b are partially connected in sequence. The first engaging unit 134a and the second engaging unit 134b form the holding portion 134 in an inward folding manner, one end of the first engaging unit 134a is at least partially connected to the spacing portion 133 of the corresponding spacing unit 132, and the side of the second engaging unit 134b opposite to the side connected to the first engaging unit 134a is at least partially connected to the spacing portion 133 of the adjacent spacing unit 132 a.

In addition, the adjacent spacing units 132a and the spacing parts 133 thereof can be folded to be perpendicular to the second engaging unit 134b (or the main plate 11) by the first folding lines 135, and the folding process is repeated to form a plurality of clamping parts 134 which are parallel to each other. In the embodiment, the first engaging unit 134a and the second engaging unit 134b form an included angle in an inward folding manner and present a V shape, and the folded first engaging unit 134a and the folded second engaging unit 134b respectively form an angle with the spacing portion 133, which may be between 95 degrees and 105 degrees. By the aforementioned folding, the spacer 133 is disposed in a direction perpendicular to the main board 11, and the clip 134 is disposed in a direction parallel to the main board 11.

After the object is placed in the space between the clamping portions 134, the cover 12 of the body 10 is folded back, so as to close the packaging structure 1. The packaging structure 1 of the present embodiment further has side clamping plates (a plurality of upper clamping plates 20 and a plurality of lower clamping plates 20a), which can achieve better sealing effect.

Fig. 6A and 6B are schematic views of the side clamping plate shown in fig. 2 disposed on the body, please refer to fig. 3, 4, 6A and 6B. It should be noted that fig. 6A exemplifies the upper side plate 20 for the sake of simplicity. The upper clamp plate 20 and the lower clamp plate 20a are respectively disposed on the upper side and the lower side of the side plate 13 of one of the bodies 10. The packaging structure 1 of the present embodiment has two main bodies 10, two upper clamping plates 20 and two lower clamping plates 20a, so the upper clamping plates 20 and the lower clamping plates 20a are respectively disposed on the upper side or the lower side of the side plate 13 of one of the main bodies 10. In the present embodiment, the upper clamping plate 20 includes an upper connecting portion 21 and an upper cover portion 22. One end of the upper connecting portion 21 has a plurality of upper engaging grooves 211, and the upper cover plate 22 is connected to the other end of the upper connecting portion 21. In addition, the upper card slots 211 are respectively inserted into the clamping portions 134. Preferably, the width of the upper card slot 211 is greater than or equal to 2 times the thickness of the clamping portion 134, that is, the width of the upper card slot 211 is greater than or equal to the sum of the thicknesses of the first engaging unit 134a and the second engaging unit 134b, so that the upper card slot 211 can be inserted into the clamping portion 134 (including the first engaging unit 134a and the second engaging unit 134 b).

Similarly, the lower clamp plate 20a includes a lower connecting portion 21a and a lower cover plate portion 22 a. One end of the lower connecting portion 21a has a plurality of lower engaging grooves 211a, and the lower cover plate portion 22a is connected to the other end of the lower connecting portion 21 a. In addition, lower card slots 211a are respectively inserted into clamping portions 134. Preferably, the width of the lower card slot 211a is greater than or equal to 2 times the thickness of the clamping portion 134, so that the lower card slot 211a can be inserted into the clamping portion 134 (including the first engaging unit 134a and the second engaging unit 134 b).

In this embodiment, only the side plate 13 needs to be folded to form a plurality of parallel clamping portions 134, and then the upper clamping groove 211 of the upper clamping plate 20 is directly inserted into the upper side of the clamping portion 134, and the lower clamping groove 211a of the lower clamping plate 20a is inserted into the upper side of the clamping portion 134, so as to form the complete packaging structure 1 having the (long-side) cover plate 12 and the (short-side) cover plate 22, thereby increasing the sealing effect of the packaging structure 1. Compared to the conventional package structure 9 with the transverse partition 92 and the longitudinal partition 93, the package structure 1 of the present embodiment can simplify the assembly process. In addition, when the packaging structure 1 is stored, the body 10, the upper clamp 20 and the lower clamp 20a can be stacked flatly, so that the upper clamping groove 211, the lower clamping groove 211a, and the subsequent first clamping groove 138 and second clamping groove 139 cannot be damaged due to stacking.

Preferably, the spacing unit 132 of the present embodiment has two first engaging slots 138 respectively located at two sides of the clamping portion 134 and located at the upper side of the side plate 13. Specifically, the first engaging groove 138 is located above the connection between the first engaging unit 134a and the spacer 133 and above the connection between the second engaging unit 134b and the spacer 133. The first engaging groove 138 extends upward from the connection between the first engaging unit 134a and the spacer 133 or extends upward from the connection between the second engaging unit 134b and the spacer 133. In addition, the spacing units 132 also have two second engaging slots 139 respectively, which are also located at two sides of the clamping portion 134, but located at the lower side of the side plate 13. Specifically, the second engaging groove 139 is located below the connection between the first engaging unit 134a and the spacer 133, and below the connection between the second engaging unit 134b and the spacer 133. In addition, the second engaging groove 139 extends downward from the connection between the first engaging unit 134a and the spacer 133 or extends downward from the connection between the second engaging unit 134b and the spacer 133.

When the clamping portion 134 is folded back by the third folding line 137, a gap (a first engaging groove 138 and a second engaging groove 139) for engaging is formed between the spacing portion 133 and the clamping portion 134. Then, the upper clamping groove 211 of the upper clamping plate 20 is aligned with the first clamping groove 138, and is inserted through the first clamping groove 138 to the joint between the first clamping unit 134a and the spacing part 133 and the joint between the second clamping unit 134b and the spacing part 133, so as to insert the upper clamping plate 20 on the upper side of the body 10. Similarly, the lower clamp 20a is inserted into the lower clamp groove 211a and passes through the second clamp groove 139 to the joint between the first engaging unit 134a and the spacer 133 and the joint between the second engaging unit 134b and the spacer 133, so that the lower clamp 20a is inserted into the lower side of the body 10. The bottom edge (closed end) of the upper engaging groove 211 contacts the bottom edge (closed end) of the first engaging groove 138, and the bottom edge (closed end) of the lower engaging groove 211a contacts the bottom edge (closed end) of the second engaging groove 139.

As shown in fig. 3, preferably, the sum of the height H1 of the upper card slot 211 and the height H2 of the first card slot 138 is substantially equal to the height H of the upper connecting portion 21. Similarly, the sum of the height H1 of the lower card slot 211a and the height H3 of one of the second card slots 139 is substantially equal to the height H of the lower connecting portion 21 a. Preferably, heights H1, H2, and H3 of upper card slot 211, lower card slot 211a, first card slot 138 and second card slot 139 are substantially the same, and a ratio of height H1 of upper card slot 211 (or lower card slot 211a) to height H of connecting portion 21 is 1/2.

Therefore, when the upper clamp 20 and the lower clamp 20a are disposed on the clamping portion 134 and the bottom edge of the upper clamping groove 211 contacts with the bottom edge of the first clamping groove 138 or the bottom edge of the lower clamping groove 211a contacts with the bottom edge of the second clamping groove 139, the upper connecting portion 21 and the lower connecting portion 21a can contact with each other, as shown in fig. 6B. With the above structure, the thickness of the body 10 can be maintained at the positions where the upper clamp 20 and the lower clamp 20a are disposed, and the engagement between the upper engaging groove 211 and the first engaging groove 138 and the engagement between the lower engaging groove 211a and the second engaging groove 139 can be more stable.

In addition, when the upper clamp plate 20 and the lower clamp plate 20a are disposed on the clamping portion 134, the upper connecting portion 21 and the lower connecting portion 21a are located in the main body 10, and the upper cover plate 22 and the lower cover plate 22a can be folded together with the cover plate 12 of the main body 10 to form the bottom or the top of the packaging structure 1, so as to close the packaging structure 1.

In summary, the body of the packaging structure of the present invention includes a main plate, two cover plates and a side plate, wherein the side plate is composed of a plurality of spacing units. Each of the spacing units includes a spacing portion and a clamping portion. The clamping part comprises a first clamping unit and a second clamping unit, and the first clamping unit and the second clamping unit can form a plurality of clamping parts which are arranged in parallel in an inward folding mode. The parallel arranged clamping parts can be used as the separating parts of the packaging structure to replace the transverse partition plates of the known packaging structure, so that the effect of convenient assembly can be achieved. After the packaged articles are placed in the space between the clamping parts, the packaging structure can be directly closed by the cover plate.
