DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 1

,


2


,


3


and


4


, a paperboard box according to the present invention basically is a piece of paperboard


10


and the paperboard


10


provides two opposite folding lines


131


and another two opposite folding lines


132


, which are vertical to the folding lines


131


in the middle area thereof to constitute the bottom of the paperboard box and the folding lines


131


each at both ends thereof provide a slant split line


11


extending outward to the right and the left side edges thereof respectively such that two opposite lower pieces


14


are formed with a trapezoid shape. Further, a first lateral piece


15


and a second lateral piece


16


are constituted next to the folding lines


131


and the slant split lines


11


. The lateral pieces


15


,


16


at the long outer edges thereof oppositely extend a locating ear


17


respectively as shown in FIG.


1


. An upper cover


20


as shown in

FIG. 2

is provided with a shape of polygon with two opposite slits


21


corresponding the two locating ears


17


.




The paperboard


10


can be cut along the split lines


11


to separate the lower pieces


14


from the first lateral piece


15


and the second lateral piece


16


respectively while the paperboard box is in use. Then, the lateral pieces


15


,


16


are folded up along the folding lines


131


and both ends of the first lateral piece


15


are crossly overlapped to both ends of the second lateral piece


16


respectively so that the lapped ends are fixedly joined to each other with glue or a staple.




Thus, the joined ends are disposed behind the lower pieces


14


to form a shape similar to both ends of a boat, that is, the paperboard


10


can be arranged to provide a boat like paperboard box as shown in

FIG. 3

with the inner space thereof for receiving food such as little octopus balls or the like. Finally, the upper cover


20


can be affixed to the paperboard box in a way the slits


21


being pierced with the locating ears


17


on the paperboard


10


as shown in

FIG. 4

so as to prevent the paperboard box from being entered by foreign substances. Further, it is possible for the paperboard to be piled up one after another.




Referring to

FIGS. 5

, and


6


, the second embodiment of the present invention is illustrated. The first lateral piece


15


at both ends thereof provides a further vertical split line


191


extending a distance from the long outer edge thereof respectively as shown in

FIG. 5 and

, similarly, the second lateral piece


16


at both end parts thereof provides a further vertical split line


192


extending a distance from the split edge


11


thereof to correspond to the vertical split lines


191


such that the lateral pieces


15


,


16


at both end parts thereof can be interlocked to each other by way of the split lines


191


,


192


being cut and engaging with each other as shown in FIG.


6


. Hence, the paperboard


10


can form a paperboard box with two ends thereof like both ends of a boat.




Referring to

FIGS. 7 and 8

, the third embodiment of the present invention is illustrated. The second lateral piece


16


at the long outer edge thereof extends outward an upper cover


20


with a folding line


133


in between and a locating ear


17


extends outward from the first lateral piece


15


so as to pierce a slit


21


on the upper cover


20


. Hence, a boat like paperboard box is formed as shown in FIG.


8


. It is noted that the upper cover


20


can be arranged to extend from the first lateral piece


15


instead.




Referring to

FIGS. 9

,


10


and


11


, the fourth embodiment of the present invention is illustrated. No locating ears


17


are provided in FIG.


9


and both of the lower pieces


14


extend outward beyond the end parts of the lateral pieces


15


,


16


. The upper cover


20


provides a plurality of split lines


22


at the periphery thereof to constitute a plurality of flap pieces


23


and two opposite slits


21


are disposed next to two opposite large ones of the flap pieces


23


as shown in FIG.


10


. The two lower pieces


14


at the outer ends


18


thereof can pierce the two slits


21


on the upper cover


20


and the flap pieces


23


are bent downward along the circular folding line


24


to enclose the paperboard box such that a further type of boat like.




Referring to

FIGS. 12 and 13

, the fifth embodiment of the present invention is illustrated. An upper cover


20


extends outward from the second lateral piece


16


and a L shaped hook ear


12


extends from the first lateral piece


15


corresponding to the slit


21


on the upper cover


20


so that the hook ear


12


can pierce the slit


21


to lock the upper cover


20


. Hence, a further type of boat like paperboard box can be formed. It is noted that the upper cover


20


can be arranged to extend from the first lateral piece


15


and the L shaped hook ear


12


to extend from the second lateral piece


16


instead.




It is appreciated from the foregoing that the paperboard box of the present invent ion offers the following advantages




1. A boat like paperboard box can be made of a piece of paperboard, which provides several split lines and folding lines so as to form folded parts for being overlapped each other. The boat like paperboard box presents a lovely configuration to make food such as the little octopus balls inside the box worthwhile and enhance the purchase desire of the consumer. Further, the paperboard box of the present invention can solve the problem of contamination to the environment.




2. The paperboard box of the present invention provides two lateral pieces with end parts of the lateral pieces being crossly overlapped and joined to each other such that the locating ears thereof can obtain outward expanding forces to retain the upper cover firmly.




3. The paperboard box of the present invention can be provided with different types of combinations such as the box with a separate upper cover, the box without any upper cover and the box being integral with an upper cover part to meet different needs of the consumers.




While the invention has been described with reference to preferred embodiments, it is to be understood that modifications and variations may be easily made without departing from the spirit of this invention defined by the appended claims.
