Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 103220350 filed in Taiwan, R.O.C. on Nov. 14, 2014, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Technical Field of the Invention
The disclosure relates to a packaging tray, more particularly to a packaging tray which is integrated formed by a base plate and four side plates bent with respect to the base plate.
2. Description of the Related Art
During the manufacturing process in factory, semi-finished products are transported from one working station to other working station, repeatedly. However, when semi-finished products are too small or too complicated, the semi-finished products are not suitable for direct transportation. Therefore, manufacturers put these kinds of semi-finished products on packaging trays for transportation in order to prevent the semi-finished products from damage.
The packaging tray is usually made from a single plate that is cut into a base sub-plate and four side sub-plates. The base sub-plate is located at the center of the plate, and the four side sub-plates surround the base sub-plate. The side sub-plates are bent relative to the sub-base plate to erect on the brim of the base sub-plate. Parts of the adjacent two side sub-plates can be overlapped with each other and fixed via staples to form the packaging tray for transportation. Another kind of packaging tray is also made from a single plate. The plate is cut into a base sub-plate and four side sub-plates. The base sub-plate is located at the center of the plate and the four side sub-plates surround the base sub-plate. The side sub-plates are bent relative to the base sub-plate to erect on the brim of the base sub-plate. Parts of the adjacent side sub-plates can be overlapped with each other and fixed via pre-cut fixing notches on the overlapped parts of the side sub-plates to form the packaging tray for transportation.
Although the two kinds of packaging trays described above can transport semi-finished products, there are some problems during assembling, using and storage. On the one hand, the first packaging tray fixed by the staples increases the cost of assembling. The overlapped parts are not convenient to be detached and leveled. Therefore, the first packaging tray needs more space for storage when they are not in use. On the other hand, the second packaging tray fixed by fixing notches is detachable for storage when they are not in use. However, the two fixing notches may be separated with each other accidentally during transportation. As a result, manufacturers try to develop a detachable packaging tray which is easily assembled and firmly fixed.

SUMMARY OF THE INVENTION

A packaging tray comprises a base plate, two first side plates and two second side plates. The base plate has two first sides and two second sides. The two first sides are opposite to each other. The two second sides are opposite to each other and located between the two first sides. The two first side plates, which are bendable relative to the base plate, are connected to and erected on the first sides of the base plate, respectively. Each of the first side plates comprises a first base body and two first combining areas. The first combining areas are connected to two sides of the first base body which are opposite to each other, respectively. Each of the first combining areas have at least one opening being separated from edges of the first combining area by a distance. The two second side plates, which are bendable relative to the base plate, are connected to and erected on the second sides of the base plate, respectively. Each of the second side plates comprises a second base body and two second combining areas. The second combining areas are connected to two sides of the second base body, respectively. Each of the second combining areas comprises a head part and a neck part. The head part and the second base body are connected via the neck part. The head parts are wider than the openings. The neck parts are narrower than the openings. The first combining areas of the first side plates are overlapped with the second combining areas of the second side plates adjacent to the first combining areas of the first side plates, respectively. The head parts pierce through and are fixed to the openings, respectively, so that the first combining areas are attached with the second combining areas, respectively. The base plate, the first side plates and the second side plates are formed into a single unit.

In this embodiment of the disclosure, the packaging tray 100 comprises a base plate 10, two first side plates 20 and two second side plates 30. The base plate 10, the first side plates 20 and the second side plates 30 are formed into a single unit.
The base plate 10 has two first sides 11 and two second sides 12. The two first sides 11 are opposite to each other. The two second sides 12 are opposite to each other and located between the two first sides 11.
The two first side plates 20 are bendable relative to the base plate 10. Moreover, the first side plates 20 are connected to and erected on the first sides 11 of the base plate 10, respectively. Each of the first side plates 20 comprises a first base body 21 and two first combining areas 22.
The two first combining areas 22 are connected to two sides of the first base body 21 which are opposite to each other, respectively. Each of the first combining areas 22 has at least one opening 221 being separated from edges of the first combining area 22 by a distance. That is to say, the brim of the opening 221 is not in contact with the edges of the first combining area 22.
The two second side plates 30 are bendable relative to the base plate 10. Moreover, the two second side plates 30 are connected to and erected on the second sides 12 of the base plate 10, respectively. Each of the second side plates 30 comprises a second base body 31 and two second combining areas 32. The second combining areas 32 are connected to two sides of the second base body 31 that are opposite to each other, respectively.
Each of the second combining areas 32 comprises a head part 321, a neck part 322 and a base part 323. The head parts 321 and the base parts 323 are connected via the neck parts 322, respectively. One end of the base parts 323 is connected to the second base bodies 31. Three sides of the head parts 321 and the necks part 322 are surrounded by the base parts 323. The head parts 321 are wider than the openings 221. Furthermore, the width of the neck parts 322 are narrower than or equal to the width of the openings 221. The lengths of the neck parts 322 are larger than the thickness of the first side plates 20.
In the embodiment above, referring to FIG. 1A, the numbers of the opening 221 of each first combining area and the numbers of the head part 321 and the neck part 322 of each second combining area 32 matched with the opening 221 are one. However, the disclosure is not limited to the numbers of the opening, the head part and the neck part. In other embodiment of the disclosure, the numbers of the opening of each first combining area and the numbers of the head part and the neck part of each second combining area are more than one.
The following describes assembling steps of the packaging tray of the embodiment of the disclosure. The first side plates 20 and the second side plates 30 are bent relative to the base plate 10 along the first sides 11 and the second sides 12, respectively, so that the first side plates 20 and the second side plates 30 are erected on the first side 11 and the second side 12, respectively. The second combining areas 32 of the second side plates 30 are bent relative to the second base bodies 31 so that the first combining areas 22 are overlapped with the second combining areas 32 of the second side plates 30 adjacent to the first combining areas 22 of the first side plates 20, respectively. Moreover, the head parts 321 and the neck parts 322 are pressed so that the head parts 321 pierce through the openings 221 and the neck parts 322 penetrates through and stay in the openings 221. Then, the bending parts of the head parts 321, which are bent, are leveled and attached to the first combining areas 22, respectively. As a result, the head parts 321 and the base parts 323 are located at two surfaces of the first combining area 22 which are opposite to each other, respectively, so that the first combining areas 22 and the second combining areas 32 are attached and fixed with each other, respectively.
In the above embodiment of the disclosure, the second combining areas 32 of the second side plates 30 are bent relative to the second base bodies 31 of the second side plates 30 to attach the first combining areas 22 of the first side plates 20, respectively. However, the disclosure is not limited to the bending and attachment relationship mentioned above. In other embodiment of the disclosure, the first combining areas of the first side plates are bent relative to the first base bodies of the first side plates to attach the second combining areas of the second side plates, respectively.
The following describes another embodiment of the disclosure, please refer to FIG. 3A and FIG. 3B. FIG. 3A is a schematic view of a packaging tray according to another embodiment of the disclosure. FIG. 3B is a top view of the packaging tray before assembling according to the embodiment of the disclosure. In this embodiment of the disclosure, the packaging tray 200 comprises a base plate 40 and four side plates 50. The base plate 40 and the side plates 50 are formed into a single unit.
The base plate 40 has two first sides 41 and two second sides42. The two first sides 41 are opposite to each other. The two second sides 42 are opposite to each other and located between the two first sides 41.
The four side plates 50 are bendable relative to the base plate 40. Furthermore, the four side plates 50 are connected to and erected on the first sides 41 and the second sides 42 of the base plate 40, respectively. Each of the side plates 50 comprises a base body 51, a first combining area 52 and a second combining area 53. The first combining areas 52 and the second combining areas 53 are connected to two sides of the base body 51 which are opposite to each other, respectively.
Each of the first combining areas 52 has at least one opening 521 being separated from edges of the first combining area 52 by a distance. Each of the second combining areas 53 comprises at least one head part 531, at least one neck part 532 and a base part 533. The head parts 531 and the base parts 533 are connected via the neck parts 532, respectively. One end of the base parts 533 is connected to the base bodies 51, respectively. Three sides of the head parts 531 and the neck parts 532 are surrounded by the base parts 533, respectively. The head parts 531 are wider than the openings 521. The width of the neck parts 532 are narrower than or equal to the width of the openings 521. The lengths of the neck parts 532 are larger than the thickness of the side plates 50.
In the embodiment above, referring to FIG. 3A, the numbers of the opening 521 of each first combining area 52 and the numbers of the head part 531 and the neck part 532 of each second combining area 53 matched with the opening are one. However, the disclosure is not limited to the numbers of the opening, the head part and the neck part. In other embodiment of the disclosure, the numbers of the opening of each first combining area and the numbers of the head part and the neck part of each second combining area are more than one.
The following describes assembling steps of the packaging tray of the embodiment of the disclosure. The side plates 50 are bent relative to the base plate 40 along the first sides 41 and the second sides 42, respectively, so that the side plates 50 are erected on the first side 41 and the second side 42, respectively. The second combining areas 53 of the side plates 50 are bent relative to the base bodies 51 so that the first combining areas 52 are overlapped with the second combining areas 53 of the side plates 50 adjacent to the first combining areas 52 of the side plates 50, respectively. In addition, the head parts 531 and the neck parts 532 are pressed so that the head parts 531 pierce through the openings 521 and the neck parts 532 penetrate through and stay in the openings 521, respectively. Then, the bending parts of the head parts 531 which are bent are leveled and attached to the first combining areas 52, respectively. As a result, the head parts 531 and the base parts 533 are located at two surfaces of the first combining area 52 which are opposite to each other, respectively, so that the first combining areas 52 and the second combining areas 53 are attached and fixed with each other, respectively.
In the two foregoing embodiments of the disclosure, the neck parts and the base bodies are connected by the base parts, respectively. However, the disclosure is not limited to the disposition of the base part. In other embodiment of the disclosure, the neck parts and the base bodies are directly connected with each other without the base bodies.
In the two foregoing embodiments of the disclosure, the packaging tray is made of corrugated paper. However, the composition of the packaging tray is not the limit of the disclosure. In other embodiment of the disclosure, the packaging tray is made of metal or polymer.
According to the packaging tray disclosed in the embodiment of the disclosure, each first combining area and each second combining area are attached and fixed by the head part piercing through the opening. As a result, there is no extra fixing components (e.g. staples) for fixing the structure of the packaging tray.
In addition, the width of the head part is larger than the width of the opening so as to avoid accidental separation of the first combining area and the second combining area during transportation.
Moreover, the first combining area and the second combining area are detached by separating the head part and the opening so that the packaging tray is leveled to be a planar plate for storage when the packaging tray is not in use.
