Description

FIELD OF THE INVENTION

The present invention relates to an angle cushioning structure for packaging, and particularly to an angle cushioning structure for packaging formed through bending, overlapping, locking and fastening means.

BACKGROUND OF THE INVENTION

Along with the precision trend of technology products, in order to prevent damages caused by impacts during a transportation process of products, many manufacturers and industrialists adopt cushioning materials for preventing impacts during packaging and transportation processes. In current applications, an angled cushioning structure is frequently placed at corner positions of an object to be transported. However, current angled cushioning structures not only have timing consuming manufacturing processes but also occupy large spaces.

For example, the Taiwan Patent Publication No. 390340 discloses “Packaging Angled Paper Formed by Pulp”. The angled paper in the above disclosure is L-shaped angled paper formed from drying pulp poured into a mold. The process of drying and parching the pulp in the mold into the L-shaped angled paper requires a long waiting period. Further, the formed L-shaped angled paper is an inflexible structure having a fixed form, and cannot be stored by a flatly stacked means, such that excessive storage spaces may be occupied for storage while the transportation process of the L-shaped angled paper is also disfavored. For another example, the Taiwan Patent Publication No. 516507 discloses “Improved Cardboard Corner Protecting Structure”. The above disclosure involves multiple cardboards adhered to one another to form a multilayer paper plate in advance, and the paper plates are stacked on one another to form an integral structure. An enclosing paper sheet is used to enclose the above integral multilayer structure, which is eventually pressed by a mold into an L-shaped protective angled paper structure. However, such conventional angled paper structure also needs to be pressed by a mold in order to form an L-shaped protective angled paper structure. Thus, this disclosure similarly consumes a large amount of time, and the formed L-shaped angled paper is an inflexible structure having a fixed form, and cannot be stored by a flatly stacked means, such that excessive storage spaces may be occupied for storage while the transportation process of the L-shaped angled paper is also disfavored.

SUMMARY OF THE INVENTION

The primary object of the present invention is to solve the issue of having a time consuming manufacturing process of a conventional angled cushioning structure.

The secondary object of the present invention is to solve the issue of storage and transportation complications of a conventional angled cushioning structure.

To achieve the above objects, the present invention provides an angled cushioning structure for packaging. The angled cushioning structure for packaging includes a cushioning body, a first side plate and a second side plate. The cushioning body includes a bending line connecting two opposite sides of the cushioning body. The bending line includes a plurality of connecting sections and a plurality of protruding cut sections arranged at an interval. Openings of two of the protruding cut sections are in different directions. The first side plate and the second side plate are connected to two corresponding sides of the cushioning body parallel to the bending line, respectively. The first side plate includes a first fastening portion, which is disposed in a protruding manner at one side of the first side plate away from the cushioning body and disposed correspondingly to one of the protruding cut sections. The second side plate includes a second fastening portion, which is disposed in a protruding manner at one side of the second side plate away from the cushioning body, and is disposed correspondingly to one of the protruding cut sections. When the first side plate and the second side plate are bent towards the cushioning body and become overlapped, the bending line on the cushioning body is bent, such that the cushioning body forms an assembly space at a position corresponding to each protruding cut section to allow the first fastening portion or the second fastening portion to be locked and fastened in the assembly space. When the first fastening portion and the second fastening portion are locked and fastened in the assembly space, the cushioning body is caused to have a bending angle.

In one embodiment, the first side plate includes a first abutting section, which is disposed in a protruding manner at one side of the first side plate away from the cushioning body and connected to the first fastening portion. After the first side plate is bent towards the cushioning body, the first abutting section abuts against the cushioning body.

In one embodiment, a distance by which the first fastening portion protrudes out of the first side plate is greater than a distance by which the first abutting portion protrudes out of the first side plate.

In one embodiment, the second side plate includes a second abutting portion, which is disposed in a protruding manner at one side of the second side plate away from the cushioning body and connected to the second fastening portion. After the second side plate is bent towards the cushioning body, the second abutting section abuts against the cushioning body.

In one embodiment, a distance by which the second fastening portion protrudes out of the second side plate is greater than a distance by which the second abutting portion protrudes out of the second side plate.

In one embodiment, the first fastening portion includes a inclined surface at one end away from the cushioning body, and the second fastening portion includes the inclined surface at one end away from the cushioning body.

In one embodiment, between surfaces of the first fastening portion and the first side plate is a drop, and between surfaces of the second fastening portion and the second side plate is also the drop.

In one embodiment, the cushioning body, the first side plate and the second side plate are a formed integral. In one embodiment, the connecting sections on the bending line are in a semi-detached form after having been cut, and the protruding cut sections are in a fully cut form.

In one embodiment, the first side plate is connected to the cushioning body by a first bending line, and the second side plate is connected to the cushioning body by a second bending line.

In one embodiment, the angled cushioning structure for packaging includes a plurality of connecting adhesive pads for connecting the first side plate or the second side plate to the cushioning body.

In one embodiment, a total width of the first side plate and the second side plate is smaller than a width of the cushioning body.

Through the above technical solutions, the present invention provides following advantages compared to the prior art.

First of all, in the implementation process of the structure of the present invention, by bending the first side plate and the second side plate towards the cushioning body and then bending the cushioning body, the first fastening portion of the first side plate and the second connecting portion of the second side plate are caused to lock in the assembly space of the cushioning body to form the angled cushioning structure for packaging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, an angled cushioning structure for packaging of the present invention is made from a cushioning plate material. For example, the plate material may be corrugated paper, a plastic material, or other materials having appropriate rigidness. The angle cushioning structure for packaging includes a cushioning body 1, a first side plate 2 and a second side plate 3. The cushioning body 1 includes a bending line 11 connecting two opposite sides of the cushioning body 1. The bending line 11 includes a plurality of connecting sections 111 and a plurality of protruding cut sections 115 arranged at an interval. Further, in one embodiment of the present invention, using a cutting depth of a cutting blade, the connecting sections 111 on the bending line 11 may appear as semi-detached, and the protruding cut sections 115 may appear as fully detached. In one embodiment of the present invention, for example but not limited to, the protruding cut section 115 may be designed to have U-shaped, triangular, zigzagged, or arched contours. To more clearly explain the present invention, these connecting sections 111 are defined as a first connecting section 112, a second connecting section 113 and a third connecting section 114. Further, these protruding cut sections 115 are defined as a first protruding cut section 116 and a second protruding cut section 117. In the embodiment, opens of the first protruding cut section 116 and the second protruding cut section 117 are designed to have different directions. For example, referring to FIG. 1, the opening of the first protruding cut section 116 faces the second side plate 3, and the opening of the second protruding cut section 117 faces the first side plate 2. The order of these sections on the bending line 11 is described in detail below. Regarding one end of the cushioning body 1 as a starting point, on the bending line 11 are sequentially the first connecting section 112, the first protruding cut section 116, the second connecting section 113, the second protruding cut section 117 and the third connecting section 114, and so forth. When the cushioning body 1 is bent along the bending line 11, the position corresponding to the first protruding cut section 116 forms a first protrusion 118 that protrudes relatively to the bending line 11 and towards the first side plate 2, and the position corresponding to the second protruding cut section 117 forms a second protrusion 119 that protrudes towards the second side plate 3. However, a hollow is formed at the position of the first protruding cut section 116 to provide a first assembly space 12, and a hollow is formed at the position of the second protruding cut section 117 to provide a second assembly space 13.

In one embodiment, the first side plate 2 and the second side plate 3 are connected to two opposite sides of the cushioning body 1 parallel to the bending line 11. The first side plate 2 includes a first fastening portion 21. The first fastening portion 21 is disposed in a protruding manner at one side of the first side plate 2 away from the cushioning body 1, and is disposed correspondingly to the second protruding cut section 117. The first side plate 2 may further include a first abutting portion 22. The first abutting portion 22 is disposed in a protruding manner at one side of the first side plate 2 away from the cushioning body 1, and is connected to the first fastening portion 21. The first fastening portion 21 abuts against the cushioning body 1 when the first side plate 2 is bent towards the cushioning body 1. In one embodiment, a distance by which the first abutting portion 22 protrudes out of the first side plate 2 is smaller than a distance by which the first fastening portion 21 protrudes out of the first side plate 2. Further, the second side plate 3 includes a second fastening portion 31. The second fastening portion 31 is disposed at a protruding manner at one side of the second side plate 3 away from the cushioning body 1, and is disposed correspondingly to the first protruding cut section 116. The second side plate 3 further includes a second abutting portion 32. The second abutting portion 32 is disposed in a protruding manner at one side of the second side plate 3 away from the cushioning body 1, and is connected to the second fastening portion 31. The second abutting portion 32 abuts against the cushioning body 1 after the second side plate 3 is bent towards the cushioning body 1. Further, a distance by which the second abutting portion 32 protrudes out of the second side plate 3 is smaller than a distance by which the second fastening portion 31 protrudes out of the second side plate 3.

In one embodiment, the cushioning body 1, the first side plate 2 and the second side plate 3 are a formed integral. Between the first side plate 2 and the cushioning body 1 is a first bending line 23, and between the second side plate 3 and the cushioning body 1 is a second bending line 33. Thus, the first side plate 2 and the second side plate 3 are allowed to bend relatively to the cushioning body 1 along the first bending line 23 and the second bending line 33, respectively.

To increase the smoothness of the first side plate 2 and the second side plate 3 bending relatively to the cushioning body 1, the first bending line 23 and the second bending line 33 may be caused to appear as semi-detached through setting a cutting depth of a cutter blade in a manufacturing process. In addition to the above embodiments, in another embodiment, the cushioning body 1, the first side plate 2 and the second side plate 3 are individually formed, and the first side plate 2 and the second side plate 3 are attached to the cushioning body 1 using a plurality of connecting adhesive pads after having been manufactured.

In one embodiment, a total width of the first side plate 2 and the second side plate 3 is smaller than a width of the cushioning body 1, as shown in FIG. 6. As such, when the first side plate 2 and the second side plate 3 are bent towards the cushioning body 1 and become overlapped, between the first side plate 2 an the second side plate 3 is a gap. The gap prevents the first side plate 2 and the second side plate 3 from forming excessive intervention during the process of bending the cushioning body 1 along the bending line 11, thereby facilitating the application of the present invention.

Referring to FIG. 1 to FIG. 7, the implementation process of the angled cushioning structure for packaging of the present invention is given in detail below. As shown in FIG. 1, the angled cushioning structure for packaging of the present invention is a flat pattern when not in use. To apply the angled cushioning structure for packaging of the present invention for packaging, a user is only required to bend the first side plate 2 along the first bending line 23 towards the cushioning body 1, and to bend the second side plate 3 along the second bending line 33 towards the cushioning body 1, as shown in FIG. 4. Thus, the first side plate 2 is overlapped on the cushioning body 1, such that each first fastening portion 21 is correspondingly overlapped at the second protruding cut section 117, as shown in FIG. 5. The user may then bend the second side plate 3 to overlap the second side plate 3 on the cushioning body 1, such that each second fastening portion 31 is correspondingly overlapped at the first protruding cut section 116, as shown in FIG. 6. The user may next bend the bending line 11 of the cushioning body 1 to cause each first fastening portion 21 to correspondingly lock and fasten in the second assembly space 13 of the second protruding cut section 117, and each second fastening portion 31 to correspondingly lock and fasten in the first assembly space 12 of the first protruding cut section 116, as the locked and fastened configuration shown in FIG. 3. The completed angled cushioning structure for packaging has a bending angle 14, as shown in FIG. 7. Accordingly, after the bending process, the present invention is capable of reliably attaching in a non-fixed manner at an angled position of an object to be packaged by the bending angle 14.

Referring to FIG. 8, in one embodiment, the first fastening portion 21 includes an inclined surface 211 at one end away from the cushioning body 1, and the second fastening portion 31 similarly includes the inclined surface at one end away from the cushioning body 1. Thus, after the first side plate 2 is bent towards the cushioning body 1 and the bending line 11 of the cushioning body 1 is bent, the inclined surface 211 of the first fastening portion 21 allows the first fastening portion 21 of the first side plate 2 to be easily locked and fastened in the second assembly space 13. The inclined surface 211 of the second fastening portion 31 has the same effect, and such details shall be omitted herein. In addition to the above embodiments, according to the embodiment of the present invention disclosed in FIG. 9, a drop 212 is present between surfaces of the first fastening portion 21 and the first side plate 2, and the drop 212 may also be present between surfaces of the second fastening portion 31 and the second side plate 3. After the first side plate 2 is bent towards the cushioning body 1 by bending the bending line 11 of the cushioning body 1, the drop 212 between the first fastening portion 21 and the first side plate 2 allows the first fastening portion 21 of the first side plate 2 to be easily locked and fastened in the second assembly space 13. It should be noted that, the disclosed embodiments of the present invention are examples for explaining the present invention, and are not to be construed as limitations to the present invention.
