## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a container, and more particularly to an assembled container having an enhanced combining strength between a body and an upper collar of the container.
2. Description of Related Art
A conventional container, such as a flowerpot may have an upper collar in a curved cross section formed on the open top of the container to improve the appearance of the container. To enhance the structural strength of the open top of the container, the upper collar may have a thickness larger than that of the body of the container. Accordingly, when a user holds the upper collar to transport the container with the containing object inside the container, the thick upper collar can bear the whole weight of the container with the containing object. However, to form a body with a thick collar with an injection molding process is time consuming because the shrinking times for the body and the upper collar of the conventional container are different.
With reference to FIG. 8, a conventional flowerpot comprises a body and an upper collar. The upper collar 30 is mounted on the open top of the body and comprises a collar segment 32 and an annular sheet 31. The collar segment 32 is integrally formed around the open top of the body, and the annular sheet 31 is connected to the collar segment 32 by an engagement manner.
However, the engagement manner between the collar segment 32 and the annular sheet 31 cannot have a large width otherwise easily causes damages of the collar segment 32 and annular sheet 31. Furthermore, the annular sheet 31 is moveable and rotatable relative to the collar segment 32 and is easily detached from the collar segment 32.
With reference to FIGS. 9 and 10, another conventional flowerpot comprises a body and an upper collar 40. The upper collar 40 comprises a skirt 50 and a collar member 60. The skirt 50 is formed on and extends downward from the open top of the body and has multiple supporting tabs 51 formed on and extending downward from a bottom of the skirt 50. An annular engaging groove 52 is defined in the bottom of the skirt 50 and engages the collar member 60 to form as the upper collar 40.
However, the arrangement of the supporting tabs 51 will cause the difficulty and complication of forming the conventional flowerpot, and the defective rate of the conventional flowerpot increases. The collar member 60 of the upper collar 40 of the conventional flowerpot is also rotatable and moveable relative to the skirt 50 and is easily detached from the skirt 50.
To overcome the shortcomings, the present invention tends to provide an assembled container to mitigate or obviate the aforementioned problems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
With reference to FIG. 1, an assembled container in accordance with the present invention comprises a body 10 and an upper collar 20.
With further reference to FIGS. 2 and 4, the body 10 is hollow and has an open top, an annular lip 11, an annular wall 12 and multiple combining blocks 14. The annular lip 11 is formed around and extends outward from the open top of the body 10 and has a top surface. The annular wall 12 is formed on and protrudes from the top surface of the annular lip 11 and has an outer surface and at least one engaging recess 13 defined in the outer surface. Preferably, the body 10 has multiple engaging recesses 13 defined separately in the outer surface of the annular wall 12 at intervals. Alternatively, the body 10 may have a single engaging recess 13 defined annularly around the outer surface of the annular wall 12. With further reference to FIG. 6, the combining blocks 14 are formed on and protrude from the top surface of the annular lip 11 at even intervals and may be U-shaped in cross section. Each combining block 14 is connected to the annular wall 12 and has a top, two side walls, a combining hole 140 and at least one engaging hole 141. The combining hole 140 is defined in the top of the combining block 14. The at least one engaging hole 141 is defined respectively through at least one of the side walls and communicates with the combining hole 140. Preferably, each combining block 14 has two engaging holes 141 defined respectively through the side walls of the combining block 140.
With reference to FIGS. 2 and 3, the upper collar 20 is connected to the open top of the body 10 and has an inner wall 22, an outer wall 21, a bottom surface, an annular recess 200, at least one engaging block 23 and multiple combining inserts 24. The annular recess 200 is defined in the bottom surface between the inner wall 22 and outer wall 21 of the upper collar 20 and has a first inner surface corresponding to the outer wall 21 of the upper collar 20. The at least one engaging block 23 is formed on the first inner surface of the annular recess 200 and respectively engages the at least one engaging recess 13 in the annular wall 12. Preferably, the upper collar 20 has multiple engaging blocks 23 formed separately on the first inner surface of the annular recess 200 or a single engaging block 23 formed annularly around the first inner surface of the annular recess 200. The combining inserts 24 are formed on and protrude from an inner top of the annular recess 200 and respectively inserted into and combined with the combining holes 140 in the combining blocks 14. Each combining insert 24 has at least one hook 241 formed on an end of the combining insert 24 and respectively engaging the at least one engaging hole 141 in a corresponding combining block 14. With reference to FIGS. 2, 6 and 7, each combining insert 24 has two resilient inserting wings 240 mounted in the combining hole 140 in the corresponding combining block 14 and being separate from each other to define a gap between the inserting wings 240. With the arrangement of the gap, the inserting wings 240 have a resilience for being pushed to be close to each other. Each inserting wing 240 has a hook 241 formed on an end of the inserting wing 240 and engaging one of the engaging holes 141 in the corresponding combining block 14. The numbers of the combining blocks 14 on the body 10 and the combining inserts 24 on the upper collar 20 may be varied based on the shapes and sizes of the container to fit with different use needs.
In addition, with reference to FIGS. 4 and 5, the annular lip 11 further has at least one curved rib 15 formed on and protruding from the top surface of the annular lip 11 at a position adjacent to the open top of the body 10 to define a combining notch 150 between each curved rib 15 and the top surface of the annular lip 11. The upper collar 20 further has at least one mounting rib 25 formed on and protruding from the bottom surface of the upper collar 20, and each mounting rib 25 has an inclined end engaging the combining notch 150 defined between one of the at least one curved rib 15 and the top surface of the annular lip 11.
When the upper collar 20 is attached to the open top of the body 10, the engaging blocks 23 on the upper collar 20 will engage the engaging recess 13 in the annular wall 12, and the mounting ribs 25 will be inserted into and engage the combining notches 150 in the body 10 so as to form an annular space between the upper collar 20 and the body 10 due to the annular recess 200. Accordingly, a sufficient structural strength is provided for bear a heavy load and material for forming the upper collar 20 can be reduced due to the hollow annular space between the collar 20 and the body 10. Because the body 10 and the upper collar 20 can be separately formed and be combined with each other easily, the cost for manufacturing the container in accordance with the present invention can be effectively reduced.
In addition, when the upper collar 20 is attached to the open top of the body 10, the combining inserts 24 on the upper collar 20 will be inserted respectively into the combining holes 140 in the combining blocks 140 on the body 10. The inserting wings 240 of the combining inserts 24 can be compressed toward each other, and hooks 241 on the combining inserts 24 will engage and hook on the engaging holes 141 in the combining blocks 14. With the engagement between the hooks 241 on the combining inserts 24 and the engaging holes 141 in the combining blocks 14, the upper collar 20 can be securely attached to the open top of the body 10 with an enhanced combining strength. Furthermore, the upper collar 20 can be kept from rotating relative to and being detached from the body 10. If soil is put into the body 10, the container can serve as a flowerpot to grow plants in the container to enable the plants to grow up and to extend upward from the open top of the body 10. With the enhanced combining structural strength between the body 10 and the upper collar 20, the container can be moved or transported to any desired location with a user holding the upper collar 20 with hands.
