1. Field of the Invention
The present invention relates to a knockdown container and, more particularly, a knockdown container could be assembled easily and quickly, and the knockdown container that can be unassembled and therefore occupy lesser storage.
2. Description of the Related Art
A conventional container or trashcan is usually made from plastic and formed via injection or that is made from metal and having a single barrel structure by bending a metal plate.
However, the foregoing conventional container or trashcan needs great storage during transportation, especially during sea transportation or long-distance land transportation. Because the barrel of the conventional container or trashcan could not be compressed, the amount of container-load or truck-load is limited and it would cause an increase of cost.
The present invention solves this need and other problems in the field of containers by providing, in a preferred form, a knockdown container including a base and a plurality of barrel members installed on the base. Each barrel member includes a first connecting portion and a second connecting portion that is set to the first connecting portion of another barrel member by sliding therethrough longitudinally. The assembly is simple and it's easy for customers assembling quickly. Furthermore, the unassembled base and barrel members could be piled on top of each other so as to save the storage on the display and the cost during transportation.

And referring to
Each barrel member 20 includes an internal surface 201, an external surface 202, a top side 203 and a bottom side 204 abutting with the upper surface of the base board 11. A first connecting portion 21 and a second connecting portion 22 are respectively defined on the left and right sides of each barrel member 20, and a barrel portion 23 is provided between the first connecting portion 21 and the second connecting portion 22. The cross section of both the first and second connecting portions 21, 22 of each barrel member 20 are form of curl and the cross section of the barrel portion 23 of each barrel member 20 is arcuate. Moreover, the first connecting portion 21 of one barrel member 20 and the second connecting portion 22 of another barrel member 20 are able to set into each other.
The first connecting portion 21 of each barrel member 20 includes a first section 211, a second section 212 connecting to the first section 211 contiguously and a third section 213 connecting to the second section 212 and the barrel portion 23 contiguously as shown in
The first section 211 is bent toward the internal surface 201 of the second section 212 and the cross section of the first section 211 is arcuate. The cross section of the second section 212 is form of flat and the internal surface 201 thereof is adapted to abut against the internal surface 201 of another barrel member 20 for preventing the first connecting portion 21 of the barrel member 20 from rotating relative to the second connecting portion 22 of another barrel member 20. The third section 213 is bent toward the internal surface 201 of the first section 211 and the cross section of the third section 213 is arcuate.
Namely, the external surface 202 of the first and second sections 211, 212 define a first receiving portion 24 therebetween, the first receiving portion 24 is adapted for receiving the fixing member 12, and the external surface 202 of the third section 213 and the internal surface 201 of the first section 211 define a second receiving portion 25 therebetween, the second receiving portion 25 is appropriately adapted for setting the second connecting portion 22 of another barrel member 20.
The second connecting portion 22 of each barrel member 20 includes a first section 221 and a second section 222 connecting to the first section 221 contiguously as shown in
The first section 221 is bent toward the internal surface 201 of the second section 222, and the internal surface 201 of the first section 221 is appropriate for the internal surface 201 of the first section 211 of another barrel member 20. The cross section of the second section 222 is form of flat and the internal surface 201 thereof is adapted to abut against the internal surface 201 of the second section 212 of another barrel member 20.
Namely, the distal end of the first section 221 and the second section 222 define a groove 26 therebetween, the groove 26 allows the second section 212 of another barrel member 20 sliding therethrough. Therefore, the structure of the barrel members 20, which are set into each other by the combination of the first connecting portion 21 of one of the barrel members 20 and the second connecting portion 22 of another barrel member 20, would be strong enough because the contact area of each two interconnecting barrel members 20 is certainly large. Moreover, the assembly of the barrel members 20 is simple.
The first and second connecting portions 21, 22 of each barrel member 20 defines a plurality of apertures 27 thereon respectively adjacent to the top and bottom sides 203, 204 of each barrel member 20, each aperture 27 is preferably a through-hole. The apertures 27 that are on the first connecting portion 21 of one of the barrel members 20 correspond to the apertures 27 that are on the second connecting portion 22 of another barrel member 20, while the two barrel members 20 interconnect as shown in
Each fastening member 30, which is adapted to be against the top side 203 of each barrel member 20 and inserting onto each first receiving portion 24 for preventing the first connecting portion 21 of one of the barrel members 20 from sliding out of the second connecting portion 22 of another barrel member 20 longitudinally, includes a cap 301 formed on an end thereof and a plurality of fastening portions 302 protruding from another end thereof. Each fastening portion 302 is in a form of hook preferably. The cap 301 is provided for abutting with the top side 203 of each two interconnecting barrel members 20 and each fastening portion 302 is form of hook and adapted for inserting through each aperture 27 on each two interconnecting barrel members 20 adjacent to the top side 203 so that the first connecting portion 21 of one of the barrel members 20 would not slide out of the second connecting portion 22 of another barrel member 20 longitudinally as shown in
Before assembling the knockdown container in accordance with the present invention, the base 10 and the barrel members 20 are form of plate structure so that it's easy to pile the components of the container on top of each other for package. And the fastening members 30 could be put between the base 10 and the barrel members 20. The package of the knockdown container is easy to put on display for sale and to carry for customers. In addition, during transportation, the amount of container-load or truck-load would increase and it would save cost.
A knockdown container in accordance with the present invention is suitable for DIY customers to assemble easily. Set a first connecting portion 21 of one of the barrel members 20 sliding longitudinally into a second connecting portion 22 of another barrel member 20, put the interconnecting barrel members 20 onto a base 10, finally install the fastening members 30 onto the barrel members 20 and finish the assembly as shown
