The packing structure according to the embodiments of the present invention is advantageous in that it is convenient for transportation, cost reducing and friendly to the environment.
The above and other features of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the accompanying drawings, in which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In this embodiment, a ventilating fan is taken as an example of an article to be packed. The external packing carton 20 is sized according to the size of a ventilating fan machine so as to accommodate the ventilating fan machine 100 (as shown in
Each of the upper surface 21 and the lower surface 23 of a commercial external packing carton 20 for packing the ventilating fan machine 100 typically consists of inner folding wings (not shown) and outer folding wings 102, which can be opened or closed. The folding portions 40 can be disposed on a side surface 22 of the external packing carton 20 which is not in the way for opening the inner folding wings and the outer folding wings 102 so as not to interfere with the opening and closing of the upper surface 21 and the lower surface 23.
The folding portion 40 can be provided on any one of the side surfaces 22 of the external packing carton 20. The folding portion 40 consists of one or more folding pieces 41 (41′), which are folded inward to the inside of the external packing carton 20 to form an opening 42. When a customer just buys the ventilating fan machine 100 without any functional unit, it is not necessary to fold the folding pieces 41 (41′) of the folding portion 40 and thus there will be no opening formed in the side surface 22 of the external packing carton 20. Therefore, the ventilating fan machine 100 can be packed in the external packing carton 20 in the same way as in the prior art.
On the other hand, if a customer buys the ventilating fan machine 100 together with functional units, the distributor can fold the folding pieces 41 (41′) of the folding portions 40 so that the side surfaces 22 of the external packing carton 20 form openings 42 of the same number as the number of the functional units, and the sizes of the respective openings 42 correspond to the sizes of the respective functional units. Then the small packing cartons 30 for packing the functional units can be inserted into the respective openings 42. Since the folding pieces 41 (41′) can be folded and the sizes of the openings 42 correspond to the sizes of the peripheries of the small packing carton 30 for packing the individual functional units, respectively, that is, the sizes of the openings 42 correspond to the lateral sectional area or the longitudinal sectional area of the small packing cartons 30, the small packing cartons 30 can fully block the openings 42 after being put into the openings 42 so that there are no gaps existing in the side surfaces 22 of the external packing carton 20 and foreign matters will not enter the external packing carton 20 from the gaps during transportation.
With the above configuration, when a customer buys a functional unit, the distributor can put a small packing carton 30 for packing the functional unit into the opening 42 provided in a side surface 22 of the external packing carton 20 to be transported conveniently; when a customer buys a plural functional units, the distributor does not need to put the small packing cartons 30 for packing a plural functional units into one additional large carton; instead, the distributor can put the small packing cartons 30 for packing the respective functional units into the openings 42 provided in the side surfaces 22 of the external packing carton 20 so that they can be transported conveniently and the cost can be reduced.
The folding pieces 41 (41′) are folded inward to the inside of the external packing carton 20 to form the opening 42. Since the folding pieces 41 (41′) are folded inward to the inside of the external packing carton 20, they will not project out of the external packing carton 20.
The folding pieces 41 (41′) include an upper piece 411 (411′), a lower piece 412 (412′), a left piece 413 (413′) and a right piece 414 (414′) combined with one another to form a rectangular shape. With the above configuration, when the upper piece 411 (411′), the lower piece 412 (412′), the left piece 413 (413′) and the right piece 414 (414′) are folded inward to the inside of the external packing carton 20, an opening 42 capable of surrounding the periphery of the small packing carton 30 for packing the functional unit can be formed to position and hold the small packing carton 30.
Referring to
Alternatively, the left and right sides of each of the upper piece 411 and the lower piece 412 can be formed as scores instead of being cut off completely, and the lower side of the upper piece 411 and the upper side of the lower piece 412 can be cut off completely instead of being formed as scores; and the intermediate side between the left piece 413 and the right piece 414 can be cut off completely instead of being formed as a score. Alternatively, the folding piece 41 can be formed so that one side thereof keeps fully connected with the side surface 22 of the external packing carton 20, and the remaining sides thereof except the one side are formed as scores or completely cut off. A person skilled in the art can choose to cut off the sides completely or form the sides as scores according to actual needs.
As shown in
When the small packing carton 30 packed with the functional unit is put into the opening 42, adhesive tapes can be adhered to the external packing carton 20 on the outside of the opening 42 to cover the opening 42. Therefore, the small packing carton 30 for packing the functional unit can be prevented from dropping off the opening 42 and it is easy for transportation.
The buffering material 50 comprises foam plastics, corrugated board, air cushion bag and other material commonly used to buffer external force and protect the ventilating fan machine 100 from damage.
The buffering material 50 separates the ventilating fan machine 100 from the external packing carton 20 by a certain distance. As shown in
The thickness of the small packing carton 30 from a side thereof on an inner side of the external packing carton 20 to a side thereof on an outer side of the external packing carton 20 is B after the small packing carton 30 for packing the functional unit is put inside the opening 42 in the side surface 22 of the external packing carton 20. If the thickness B is equal to the thickness A, after the small packing carton 30 for packing the functional unit is inserted into the external packing carton 20 from the opening 42, a side of the small packing carton 30 for packing the functional unit on the inner side of the external packing carton 20 is adjacent to the ventilating fan machine 100, and a side of the small packing carton 30 for packing the functional unit on the outer side of the external packing carton 20 is flush with the side surface 22 of the external packing carton 20 and the shell of the external packing carton 20 will not become large. After adhesive tapes are adhered to the edges of the opening 42 on the outer side of the external packing carton 20, since the small packing carton 30 is clamped and fixed between the ventilating fan machine 100 and the adhesive tapes on the side surface 22 of the external packing carton 20, the small packing carton 30 will not project out of the side surface 22 of the external packing carton 20, and thus the volume of the external packing carton 20 for packing the ventilating fan machine 100 will not increase during transportation.
As shown in
Therefore, the small packing carton 30 can be disposed in the opening 42 at a suitable depth so that the adhesive tapes can just adhere to the small packing carton 30 and the small packing carton 30 can be prevented from dropping off inside the external packing carton 20.
Further, as an example, the folding piece 41 is provided with a folding line and the stopping part 101 is formed by folding the folding piece 41 along the folding line.
Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
