1. Field of the Invention
The present invention relates to a rectangular parallelepiped paper made entrainer and more particularly, to a paper made entrainer supported by paper frameworks and columns to form the structure into a rectangular parallelepiped shape so as to easily assemble, detach and transport the cargo with less labor and cost.
2. Description of the Prior Art
The arising of environmental consciousness has called for the manufacturers in every respect to pay attention to the situation whether their products fulfil such a requirement even for basic and simplest packaging means. It is commonly known that the traditional wooden container used to pack the cargo needs a high transportation cost and an expensive material cost for its heavy wight. Besides, the detached wooden container after being performed transportation work is rarely worth of recycling use.
The paper board made entrainer has arisen to replace the position of means for transportation with the remedies easy for assembly, light in weight, low in material cost, but the most important reason is its possibility of recycling for reuse.
However, it should be understood that there are still several shortcomings inherent to the paper made entrainer namely, somewhat bulkiness, difficult to form an universal structure for use on transporting various cargoes etc.
For these shortcomings noticeable on the paper made entrainer prevailing presently, an improvement is seriously required.
Accordingly, the main object of the present invention is to provide a rectangular parallelepiped paper made entrainer assembled by four simple basic component parts so as to meet the requirement of loading variously sized and weighted cargoes by reassembling the above mentioned four component parts to vary the entrainer size conveniently and efficiently with less cost.
Another object of the present invention is to provide a rectangular parallelepiped paper made entrainer which is made of tough and anti-abrasive paper board with excellent physical properties resistive to squeezing and folding.
To achieve the above mentioned objects, the present invention provides a paper made entrainer composed of basically a transverse framework, a longitudinal framework, a supporting column and a loading board all formed of a hard paper material. The transverse and longitudinal frameworks are disposed vertical to each other and engaged together by mutually inserting the wall into the slit formed on the opponent side. The width of the slit is made equal to the thickness of the two frameworks so that they are conjoined tightly perpendicular to each other. The supporting column is configurated into a cylindrical shape and is also provided with several slits corresponding to that formed on the longitudinal and transverse frameworks. The supporting column is to support the intersection of the above two frameworks so that each supporting column supports at least one longitudinal and one transverse frameworks thereby the loading board is supported by a plurality of longitudinal and transverse frameworks to entrain a heavy load.
The drawings disclose two illustrative embodiments of the present invention which serve to exemplify various advantages and objects hereof, and are as follows:
Referring to
The transverse framework 1 is made of paper board with large strength of material such as corrugated paper or carton paper, several engagement slits 11 with a thickness equal to that of the transverse framework 1 are formed thereon. The number of slits 11 required per unit length depends on the weight of the load to be carried.
The longitudinal framework 2 is made of the similar paper material as the transverse framework 1, or even can be replaced by the former one depending one the size of the entrainer. Several engagement slits 21 similar to the engagement slits 11 are formed on the longitudinal framework 2 so as to engage the two frameworks 1 and 2 perpendicular to each other by mutually inserting its edge to the opposite slits.
The supporting column 3, configurated into a cylindrical shape, is also made of the paper material similar to that of the two frameworks 1 and 2. Several slits 31 are formed along its upper wall surface to be engaged with the intersection of the two frameworks 1 and 2 after they have been engaged with each other. By so each supporting column 3 supports at least one longitudinal framework 2 and one transverse framework 1 thereby the loading board 4 is supported on this structure by a plurality of longitudinal and transverse frameworks 2 and 1 and supporting columns 3 hence causes the loading board 4 able to carry a heavy load.
Referring to
Meanwhile, the surface of the two frameworks 1 and 2 may be reinforced by corrugation or adding ribs.
It emerges from the above description that the rectangular parallelepiped paper made entrainer of the present invention has several noteworthy advantages compared with those paper made entrainers prevailing presently, namely:
1. It comprises only three basic supporting component parts plus a loading board and is easy to assemble and detach with low labor cost.
2. Adjusting number of three supporting component parts used makes the entrainer able to carry loads of different weight.
3. The structure is simple and light to handle, decayed structure is possible for recycling.
Many changes and modifications in the above described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
