Description

Packaging structure

The present invention relates to a package structure.

Since the liquid crystal panel usually uses glass as the substrate, when the liquid crystal panel is completed, the related manufacturer will house the liquid crystal panel in a buffering capacity box to avoid damage due to external force during transportation. .

The size of the space inside the package does not necessarily match the size of the liquid crystal panel. Therefore, a plurality of stoppers can be adhered in the package, and the liquid crystal display panel is clamped between the stoppers, thereby ensuring that the liquid crystal panel can be stabilized. It is housed in the box without any shaking.

However, the package with the stopper can be used only for a liquid crystal panel of a specific size. If you want to use this box to accommodate other sizes of LCD panels, you must remove the stoppers and remove them before attaching the other sizes of stoppers to the box. This practice not only wastes man-hours, but also adds additional stops, thus increasing the cost burden.

In view of the above, it is an object of the present invention to provide a package structure having a stopper which can change the size of a region in which a package can be placed by changing the orientation of the stopper, and can accommodate various sizes of packaged packages. Things.

In order to achieve the above object, according to an embodiment of the present invention, a package structure includes a case body and at least one stopper. The box body includes a bottom plate and side plates. The side panels abut the bottom plate. The bottom plate has at least one first engaging structure. The side plate and the bottom plate surround the receiving chamber. The stopper is disposed on the bottom plate and located in the accommodating chamber surrounded by the side plate. The stopper includes a second engaging structure and a plurality of bumps. The second engaging structure is configured to engage with the first engaging structure. The second engaging structure has a bottom surface, a top surface, and a plurality of sides. These sides are adjacent between the top surface and the bottom surface. The bump is disposed on a side of the second engaging structure. The bumps have a bump length, and the lengths of the bumps of any two bumps are not equal.

In the above embodiment, the packaged object can be clamped between the bumps of the stopper, because the stopper can be engaged with the bottom plate in various different orientations, and the bump lengths of the respective bumps of the stopper are not equal to each other. Therefore, the staff can change the size of the placeable area of the package by changing the orientation of the stopper, thereby facilitating accommodation of the packaged articles of various sizes.

The above description is only for explaining the problems to be solved by the present invention, the technical means for solving the problems, the effects thereof, and the like, and the specific details of the present invention will be described in detail in the following embodiments and related drawings.

The embodiments of the present invention are disclosed in the following drawings, and for the purpose of clarity However, it should be understood by those skilled in the art that the details of the invention are not essential to the details of the invention. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

1 is a perspective exploded view of a package structure in accordance with an embodiment of the present invention. As shown in FIG. 1, the package structure of the present embodiment may include a case 100 and a stopper 200. The case 100 includes a bottom plate 110, side plates 120, and a top cover 130. The side plate 120 abuts the bottom plate 110, and the side plate 120 surrounds a receiving chamber 140. The top cover 130 may cover one side of the side plate 120 opposite to the bottom plate 110 to close the accommodating chamber 140 while preventing foreign objects from falling into the accommodating chamber 140. The stopper 200 is disposed on the bottom plate 110, and the stopper 200 is located in the accommodating chamber 140 surrounded by the side plate 120. The stopper 200 can be abutted between the packaged object in the accommodating chamber 140 and the side plate 120 to prevent the packaged article from arbitrarily shaking during transportation.

Fig. 2 is a partially exploded perspective view showing the packaging structure of Fig. 1. As shown in FIG. 2, the bottom plate 110 has a first engaging structure 112 and a bearing surface 114. The bearing surface 114 can carry the packaged object. The first engaging structure 112 is recessed on the bearing surface 114. The stopper 200 includes a second engaging structure 210 and bumps 220a, 220b, and 220c. The second engaging structure 210 has a top surface 212, a bottom surface 214 and side surfaces 216a, 216b, 216c and 216d. Sides 216a, 216b, 216c, and 216d are adjacent between top surface 212 and bottom surface 214. The bumps 220a, 220b, and 220c are respectively disposed on the side surfaces 216a, 216b, and 216c of the second engaging structure 210. The second engaging structure 210 can be engaged with the first engaging structure 112 to engage the blocking block 200 on the bottom plate 110.

The bump 220a of the stopper 200 can be used to abut the packaged object. In other words, as shown in FIG. 1, the bumps 220a of the plurality of stoppers 200 can jointly define a placeable region R therebetween, and the packaged object can be placed. It can be placed in the area R and is abutted by the bump 220a. Therefore, the size of the area R can be placed It depends on the size of the bump 220a. Further, the side panel 120 has two opposite sub-boards 121 and 123 and two opposite sub-boards 125 and 127. The bumps 220a located adjacent to the sub-plates 121 and 123, respectively, define a region length R1, and the bumps 220a located adjacent to the sub-plates 125 and 127, respectively, define a region width R2. The region length R1 and the region width R2 are both dependent on the length of the bump 220a.

In order to accommodate a variety of differently sized packages, the zone length R1 and the zone width R2 are preferably adjustable. Therefore, the present invention further provides the following technical means to adjust the region length R1 and the region width R2. Specifically, referring to FIG. 2, the stopper 200 can be disposed on the bottom plate 110 in various orientations. When the stopper 200 is disposed in an orientation different from that shown in FIG. 2, the region R can be placed (refer to FIG. 1). It may be defined by bumps 220b or 220c instead of by bumps 220a. Therefore, when the stopper 200 is disposed in an orientation different from that shown in FIG. 2, the region length R1 and the region width R2 of the placeable region R may depend on the length of the bump 220b or 220c. In order to facilitate adjustment of the region length R1 and the region width R2, the lengths of the bumps 220a, 220b, and 220c are preferably different.

Further, referring to FIG. 3, this figure shows a partial top view of the packaging structure of FIG. 1. As shown in FIG. 3, the second engaging structure 210 has a width W, the bumps 220a, 220b, and 220c have bump lengths La, Lb, and Lc, respectively, and the bumps 220a, 220b, and 220c have the same card as the second card. The width of the structure 210, that is, the width W. The bump lengths La, Lb, and Lc are not equal to each other. In this way, when the stoppers 200 are disposed in different orientations, the region length R1 or the region width R2 of the placeable region R (see FIG. 1) is different, so that it is advantageous to accommodate various sizes of the packaged articles.

For example, when the stopper 200 is disposed in the orientation shown in FIG. 3, the projection 220a is farthest from the side panel 120, so that the packaged object can be abutted, that is, the region R can be placed (see FIG. 1). The area length R1 and the area width R2 (see FIG. 1) are defined by the bump 220a depending on the width W of the second engaging structure 210 and the bump length La of the bump 220a.

When the stopper 200 is rotated 90 degrees counterclockwise from the orientation shown in FIG. 3 and is disposed at the orientation shown in FIG. 4, the projection 220b is farthest from the side plate 120, so that the packaged object can be abutted, that is, The placeable region R (see Fig. 1) is defined by the bump 220b, and the region length R1 and the region width R2 (see Fig. 1) depend on the width W of the second engaging structure 210 and the bump The bump length Lb of 220b.

When the stopper 200 is rotated 90 degrees counterclockwise from the orientation shown in FIG. 4, and is disposed in the orientation shown in FIG. 5, since the side surface 216d of the second engaging structure 210 is not provided with any bumps, the second The engaging structure 210 and the bumps 220b and 220c can together abut the packaged object, that is, the placeable area R (refer to FIG. 1) is defined by the second engaging structure 210 and the bumps 220b and 220c. The area length R1 and the area width R2 (see Fig. 1) depend on the width W of the second engaging structure 210 (equivalent to the width of the bumps 220b and 220c).

When the stopper 200 is rotated 90 degrees counterclockwise from the orientation shown in FIG. 5 and is disposed at the orientation shown in FIG. 6, the projection 220c is farthest from the side plate 120, so that the packaged object can be abutted, that is, The placeable region R (refer to FIG. 1) is defined by the bump 220c, and the region length R1 and the region width R2 are determined by the width W of the second engaging structure 210 and the bump 220c. Bump length Lc.

Referring to FIG. 1 , the stoppers 200 located beside the sub-boards 121 and 123 may be disposed in four orientations as shown in FIGS. 3 to 6 , and the sub-plates 121 and 123 may not be provided with the stopper 200 . The area length R1 of the package structure of the embodiment may have five size options; similarly, the stops 200 located beside the sub-boards 125 and 127 may be disposed in four orientations as shown in FIGS. 3 to 6, in addition, the sub-board 125 and The stopper 200 may not be provided next to the 127. Therefore, the region width R2 of the packaging structure of the present embodiment may have five sizes. Therefore, the size of the mountable region R of the package structure of the present embodiment can be selected in a total of 25 (5 × 5), so that at least 25 packages of different sizes can be accommodated.

In some embodiments, as shown in FIG. 2, the bottom surface 214 of the second engaging structure 210 has a regular polygon, such as a regular quadrangle. In addition, the first engaging structure 112 has a concave bottom surface 113 and a vertical surface 115. The vertical surface 115 connects the bearing surface 114 and the periphery of the recessed bottom surface 113 to form a groove-like structure together with the concave bottom surface 113. The shape of the recessed bottom surface 113 is the same as the shape of the bottom surface 214 of the second engaging structure 210, that is, both of them may have a regular polygon, such as a regular square. In this way, regardless of which orientation of the stopper 200 is shown in the third to sixth figures, the second engagement structure 210 can be engaged in the first engagement structure 112. In the present embodiment, the bottom surface 214 of the second engaging structure 210 and the recessed bottom surface 113 of the first engaging structure 112 are both square, but the invention is not limited thereto.

In other words, the top surface 212 and the bottom surface 214 of the second engaging structure 210 are two surfaces that are parallel and equal in area, and both are regular polygons, and the sides 216a, 216b, 216c, and 216d of the second engaging structure 210 are both It is perpendicular to the top surface 212 and the bottom surface 214. It should be understood that although the second engaging structure 210 in FIG. 2 is illustrated as a positive polygonal cylinder, the present invention is not limited thereto, as long as it can be provided at different positions of the second engaging structure 210. Different numbers of the bumps 220a, 220b, and 220c, and the second engaging structure 210 may also be other shapes of the cylinder.

In some embodiments, as shown in FIG. 2, the side panel 120 has an inner wall 122 and a notch 124. The notch 124 is recessed in the inner wall 122, and the notch 124 can be substantially aligned with the first engaging structure 112. As such, when the stoppers 200 are disposed on the bottom plate 110 in different orientations, the notches 124 can accommodate the projections 220a, 220b or 220c to prevent the inner wall 122 of the side panels 120 from interfering with the projections 220a, 220b or 220c.

In some embodiments, as shown in FIG. 3, the bump 220a has a proximal edge 222a and a distal edge 224a. The proximal edge 222a connects the second snap structure 210. The distal edge 224a is opposite and substantially parallel to the proximal edge 222a. The bump length La is the distance between the near edge 222a and the far edge 224a. The length of the proximal edge 222a and the distal edge 224a may be equal. For example, the bump 220a shown in FIG. 3 is a rectangular parallelepiped, and the proximal edge 222a and the distal edge 224a are equal in length, corresponding to the width W of the second engaging structure 210.

Similar to the bump 220a, as shown in FIG. 3, in some embodiments, the bump 220b may also have a near edge 222b and a far edge 224b. The proximal edge 222b connects the second snap structure 210. The distal edge 224b is opposite and substantially parallel to the proximal edge 222b. The bump length Lb is the distance between the near edge 222b and the far edge 224b. The bump 220b can be a rectangular parallelepiped, that is, the length of the near edge 222b and the far edge 224b can be equal, corresponding to the width W of the second engaging structure 210.

Similar to the bumps 220a and 220b, as shown in FIG. 3, in some embodiments, the bump 220c may have a near edge 222c and a far edge 224c. The near edge 222c connects the second engaging structure 210. The distal edge 224c is opposite and substantially parallel to the proximal edge 222c. The bump length Lc is the distance between the near edge 222c and the far edge 224c. The bump 220c can be a rectangular parallelepiped, that is, the length of the near edge 222c and the far edge 224c can be equal, corresponding to the width W of the second engaging structure 210.

In some embodiments, as shown in FIG. 2, the proximal edge 222a of the bump 220a is parallel to the edge E1 of the side 216a of the second engaging structure 210, and the length of the proximal edge 222a and the edge E1 may be equal. Similarly, the proximal edge 222b of the bump 220b is parallel to the edge E2 of the side 216b of the second snap structure 210, and the length of the proximal edge 222b and the edge E2 may be equal. Similarly, the near edge 222c of the bump 220c (see FIG. 3) is parallel to the edge E3 of the side 216c of the second engaging structure 210 (see FIG. 2), and the length of the near edge 222c and the edge E3 can be equal.

FIG. 7 is a partial perspective view of a case 100 according to another embodiment of the present invention. FIG. 8 is a block diagram showing the housing 100 of FIG. A partial top view of the back. As shown in the seventh and eighth embodiments, in the present embodiment, the bottom plate 110 has a plurality of limiting slots 116a, 116b, 116c and 116d, and the limiting slots 116a, 116b, 116c and 116d can accommodate the bumps 220a, 220b. Or 220c is included therein to prevent the bumps 220a, 220b or 220c from swaying at will.

Specifically, the first engaging structure 112 is located between the limiting slots 116a, 116b, 116c, and 116d, so that when the second engaging structure 210 is engaged with the first engaging structure 112, the limiting slot 116a, 116b, 116c, and 116d can accommodate bumps 220a, 220b, or 220c therein. For example, when the stopper 200 is disposed in the orientation shown in FIG. 8, the projections 220a, 220b, and 220c may fall into the limiting slots 116a, 116b, and 116c, respectively. In addition, when the stoppers 200 are disposed in different orientations (as set in the orientations shown in FIGS. 4 to 6), the projections 220a may fall into other limiting slots other than the limiting slots 116a (eg, the limiting slots 116b, 116c). Or 116d); similarly, when the stoppers 200 are disposed in different orientations, the bumps 220b may fall into other limiting slots (such as the limiting slots 116a, 116c or 116d) other than the limiting slots 116b; When the stoppers 200 are disposed in different orientations, the bumps 220c may fall into other limiting slots (such as the limiting slots 116a, 116b or 116d) other than the limiting slots 116c.

In some embodiments, as shown in FIG. 8, the bumps 220a, 220b, and 220c each have opposite abutting faces 226a, 226b, and 226c. When the stopper 200 is disposed in the orientation shown in FIG. 8, the abutting surfaces 226a of the projections 220a abut against the inner wall of the limiting groove 116a, and are fixed by the inner wall of the limiting groove 116a. . Similarly, in some embodiments, the abutting surfaces 226b of the bumps 220b abut against the inner wall of the limiting slot 116b to be fixed by the inner wall of the limiting slot 116b. Similarly, partially implemented In the embodiment, the abutting surfaces 226c of the protrusions 220c abut against the inner wall of the limiting groove 116c, and are fixed by being clamped by the inner wall of the limiting groove 116c. It should be noted that as long as one of the bumps 220a, 220b, and 220c is clamped, it can help prevent the stopper 200 from arbitrarily shaking, and not all of the bumps 220a, 220b, and 220c need to be clamped. Of course, preferably, when the bumps 220a, 220b, and 220c are both clamped, the stopper 200 is most stable.

In some embodiments, as shown in FIG. 8, the bumps 220a, 220b, and 220c each have an equal maximum width W1 of the bumps. The maximum width W1 of the bump is defined between the two abutting faces 226a (or 226b, or 226c). In other words, the maximum width W1 of the bump is the distance between the two abutting faces 226a (or 226b, or 226c). The limit grooves 116a, 116b, 116c, and 116d each have an equal groove width W2. The groove width W2 is equal to the maximum width W1 of the bump. In this way, when the stopper 200 is disposed in any orientation, the bumps 220a, 220b, and 220c can be clamped.

In some embodiments, as shown in FIG. 8, the abutting faces 226a of the bumps 220a are parallel to each other, so that when the bumps 220a are located in the limiting slots 116a (or the limiting slots 116b, 116c or 116d), All of the areas of the abutment faces 226a are able to abut against the inner walls of the stop slots 116a (or the limit slots 116b, 116c or 116d) to make the stops 200 more stable. Similarly, the abutting faces 226b of the bumps 220b may be parallel to each other, and the abutting faces 226c of the bumps 220c may also be parallel to each other.

In some embodiments, as shown in FIG. 8, the limit grooves 116a, 116b, 116c, and 116d each have an equal groove length Lg. The groove length Lg is equal to the bump length La of the longest bump 220a. In this way, the limit slot Each of the 116a, 116b, 116c, and 116d can accommodate the bump 220a. Since the limiting slots 116a, 116b, 116c and 116d can accommodate the longest bumps 220a, the shorter bumps 220b and 220c can also be accommodated, so that the blocking blocks 200 can be arranged in different orientations.
