20140166531
The present invention relates to a paper-made packing box for displaying object therein, and more particularly, to a paper-made packing box with a shock-absorbing device located therein so as to protect the object in the packing box.
The conventional packing boxes for display objects can be cataloged into two types, one of which partially packs the object and the other one fully packs the object in the box.
The conventional packing boxes are developed with convenient handles, commercial advertisement surfaces, outer appearances, and shock-absorbing feature.
For the packing box with shock-absorbing feature, polymer particles or boards and bubble sheets are used to wrap the object so as to protect the object from being damaged by vibration or impacts. The latest packing box has multiple positioning recesses defined by folding flaps of the box and preferably, the packing box is made by a single paper sheet.
Taiwan Utility Model Application No. 097101935 discloses a packing box with two side panels and two support portions are formed on the underside of the packing box. Each of the support portions has a top face, a bottom face, a first side face connected with the first side panel and a second side face located corresponding to the first side face. The side panels are folded toward the interior of the packing box so as to form the bottom face, the second side face, the top face and the first side face in sequence. The top face and the second side face respectively have a notch facing the recessed area of the support portions.
Taiwan Utility Model Application No. 098200169 discloses a packing box with a cover connected to two side panels thereof, a bottom plate and multiple folded plates. The multiple separation plates are located between the cover, the bottom plate and the folded plates. The outmost separation plate has a connection plate and the separation plate located close to the bottom plate has a hole. The folded plates each have a positioning hole and the position holes are located corresponding to each other.
Taiwan Utility Model Application No. 100212177 shows a packing box with multiple connected side walls and the walls comprise a top wall, a side wall and a bottom wall. The side wall comprises a first side wall connected between the top wall and the bottom wall, and a second side wall connected to the bottom wall. A folding line is defined between the top wall and the first side wall, another folding line is defined between the first side wall and the bottom wall, yet another folding line is defined between the second side wall and the bottom wall. The second side wall is connected to the top wall so as to define the packing box with a hollow interior. The top wall is shaped geometrically and the shape has a folding line and a flap connected to folding line so as to retain an object.
Taiwan Utility Model Application No. 097101935 uses the recessed area of the support portions to position the object. Taiwan Utility Model Application No. 098200169 provides holes for position the object wherein the holes allow a larger sized object to be positioned. Taiwan Utility Model Application No. 100212177 uses the folding line to fold the related portion of the paper sheet to form recesses which are cooperated with flaps to position the object.
However, the shape and size of the objects are not fixed so that the packing boxes cannot meet the practical needs for positioning most of the objects. The manufacturing cost will be too high if the packing boxes are custom-made for different objects. Besides, the object in the packing box will be damaged when the packing box drops, this is because the conventional packing box lacks proper shock-absorbing device to absorb the shocks and impacts transferred to the object.
The present invention intends to provide a paper-made packing box with a shock-absorbing device located therein so as to protect the object in the packing box.
The present invention relates to a packing box and comprises a peripheral portion and two end portions are respectively connected to two ends of the peripheral portion. A shock-absorbing device has two support members located on the two ends of the peripheral portion, and the two support members each are bent to be a U-shaped member and linearly movable toward the end portion corresponding thereto. At least one positioning portion is connected to each of the support members so as to retain an object. The object is suspended and can be moved with the support members so that the energy coming from vibration and impacts is eliminated by the movement of the object with the support members.
The primary object of the present invention is to provide a packing box which has a shock-absorbing device which allows the object to swing within an acceptable range so as to eliminate the energy from vibration and impacts.
A second object of the present invention is to provide a packing box with two support members which swing back and forth to eliminate the energy from vibration and impacts.
A third object of the present invention is to provide a packing box which has a shock-absorbing device and two ends of the object is connected to the shock-absorbing device. The positioning portion of each of the support members of the shock-absorbing device can be adjusted to position the object.
A fourth object of the present invention is to provide a packing box which is made by cutting a single paper board and bending the paper board into a shock-absorbing device. The packing box is easily manufactured and used.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
A shock-absorbing device 20 has two support members 21, 22 located on the two ends of the peripheral portion 11. The two support members 21, 22 each are inserted toward the interior of the packing box 10 and bent to be a U-shaped member. Each of the bent support members 21, 22 has a distal end which contacts the peripheral portion 11. A positioning portion 23 is defined in each of the support members 21, 22 and located close to the distal end of each support member 21/22 so that an object extends through the engaging portions 23 which is hanged or suspended by the support members 21, 22. The support members 21, 22 are linearly movable toward the end portion 12 corresponding thereto. The two support members 21, 22 swing back and forth to eliminate the energy from vibration and impacts, so that the object is protected.
When manufacturing the packing box 10, the paper board is cut by proper molds and cutting tools to form the peripheral portion 11 and the shock-absorbing device 20, wherein the cutting line is solid lines and the dotted lines are folding lines as shown in
As shown in
As shown in
As shown in
The shock-absorbing device 20 is integrally formed when cutting the paper board and the height of the engaging portions 23 make the object 30 to be positioned and hanged in the packing box 10. The object 30 can swing with the support members 21, 22 to eliminate the vibration and impacts.
When the support members 21, 22 are bent, the object 30 is to be extended through the bent portions of the support members 21, 22, so that the length of the bent portion can be adjusted according to the length of the object 30. In other words, the packing box 10 can be used to pack the object of different lengths and this reduces the cost for preparing different sizes of the packing boxes.
The packing box 10 and the shock-absorbing device 20 are integrally manufactured, no polymer particles and bubble sheets are needed to be fill in the space in the packing box 10, so that the cost is reduced.
The first and second engaging units 17, 18 have plate-like first engaging portions 171, 181, 183 which are folded and engaged with the second engaging portions 172, 182, 184 to position the first and second extension portions 13, 14 and the end portions 12 to the peripheral portion 11. When in use, the first and second engaging units 17, 18 are connected to each other from outside of the packing box 20 so that the packing efficiency is higher than the conventional packing box whose extension portions have to be inserted into the box. The present invention is easily packed and unpacked.
As shown in
Because the object is light in weight so that the distal ends of the support members 21, 22 do not hit the peripheral portion 11 so the object is hanged and can swing with the support portions 21, 22. In this embodiment, the positioning portion 23 is a hole with teeth defined in the inner periphery thereof so that the object 30 extends through the positioning portion 23 with less resistance and the teeth are flexible so that the diameter of the positioning portion 23 does not have to precisely match the size of the object 30. In other words, the positioning portion 23 can be used to position objects of different sizes.
The transparent member 40 is mounted to the window 112 to prevent dust from entering the interior and the object 30 can be observed via the window 112.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
