DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Referring to FIGS. 1-4, a multipurpose infuser filter strainer 100 in accordance with the present invention is shown. The multipurpose infuser filter strainer 100 comprises a soft sieve 10, a hard sieve 20, a top cap ring 30, a bottom cap ring 40, and a soft mesh 50.

[0026] The soft sieve 10 comprises a top opening 11, an opposing bottom opening 12, and a plurality of mesh hole 13 evenly distributed through the periphery thereof between the top opening 11 and the bottom opening 12.

[0027] The hard sieve 20 surrounds the soft sieve 10, comprising a top opening 21 receiving the top opening 11 of the soft sieve 10, an opposing bottom opening 22 receiving the bottom opening 12 of the soft sieve 10, and a plurality of mesh hole 23 evenly distributed through the periphery thereof between the top opening 21 and the bottom opening 22. Accordingly, the hard sieve 20 surrounds the soft sieve 10, protecting the soft sieve from being harmed. Moreover, since the hard sieve 20 surrounds the soft sieve 10, the soft sieve 10 will not deform its shape therefore will not affect its function.

[0028] The top cap ring 30 is fastened to the top opening 21 of the hard sieve 20 to hold the top opening 11 of the soft sieve 10 in place. More specifically, the peripheral edge of the top opening 11 of the soft sieve 10 can be clamped in between the top cap ring 30 and the top opening 21 of the hard sieve 20. Further, spot welding can be applied to enhance the connection.

[0029] The bottom cap ring 40 is fastened to the bottom opening 22 of the hard sieve 20 to hold the bottom opening 12 of the soft sieve 10 in place. Further, the bottom cap ring 40 defines therein a center opening 41. More specifically, the peripheral edge of the bottom opening 12 of the soft sieve 10 can be clamped in between the bottom cap ring 40 and the bottom opening 22 of the hard sieve 20. Further, spot welding can be applied to enhance the connection.

[0030] The soft mesh 50 is mounted in the bottom cap ring 40, and covered over the center opening 41 of the bottom cap ring 40. The soft mesh 50 has a plurality of mesh holes 51 cut through opposing top and bottom surfaces thereof and evenly distributed. Further, as illustrated in FIG. 1, FIG. 2 and FIG. 4, the soft mesh 50 is fastened to the center opening 41 of the bottom cap ring 40 by a packing member 60. Thus, the packing member 60 protects the soft mesh 50 against vibration or deformation during tea infusing or coffee brewing.

[0031] As illustrated in FIG. 1, the mesh size of the mesh holes 13 of the soft sieve 10 and the mesh size of the mesh holes 51 of the soft mesh 50 are smaller than the mesh size of the mesh holes 23 of the hard sieve 20. Thus, the multipurpose infuser filter strainer 100 can be used for infusing tea as well as for brewing coffee. Preferably, the mesh size of the mesh holes 13 of the soft sieve 10 and the mesh size of the mesh holes 51 of the soft mesh 50 are larger than 170 meshes so that they can effectively filter coffee grounds when the multipurpose infuser filter strainer 100 is used for making coffee. Further, the mesh size of the mesh holes 23 of the hard sieve 20 is not particularly limited as long as it can be used to block the passage of tea leaves. In other words, the said mesh holes of said hard sieve are configured for filtering tea leaves.

[0032] Further, in order to improve the coffee brewing quality of the multipurpose infuser filter strainer 100, the mesh size of the mesh holes 13 of the soft sieve 10 and the mesh size of the mesh holes 51 of the soft mesh 50 are preferably in the range of 170-200 meshes, the mesh size of the mesh holes 13 of the soft sieve 10 and the mesh size of the mesh holes 51 of the soft mesh 50 are preferably in the range of 170-230 meshes, the mesh size of the mesh holes 13 of the soft sieve 10 and the mesh size of the mesh holes 51 of the soft mesh 50 are preferably in the range of 200-230 meshes, or most preferably 200 meshes.

[0033] Further, the soft sieve 10, the hard sieve 20, the top cap ring 30, the bottom cap ring 40 and the soft mesh 50 are preferably made of stainless steel, facilitating cleaning, mounting and positioning.

[0034] Thereafter, the application of the multipurpose infuser filter strainer 100 is outlined hereinafter with reference to FIG. 5 and FIG. 6, where FIG. 5 illustrates the application of the multipurpose infuser filter strainer 100 in infusing tea; FIG. 6 illustrates the application of the multipurpose infuser filter strainer 100 in making coffee.

[0035] As illustrated in FIG. 5, when using the multipurpose infuser filter strainer 100 to infuse tea, put tea leaves T in the space surrounded by the soft sieve 10 and the soft mesh 50, and then put the multipurpose infuser filter strainer 100 in a container 1000, and then pour an appropriate amount of hot water W in the space surrounded by the soft sieve 10 and the soft mesh 50 to infuse the tea leaves T. When infusing the tea leaves T with hot water W, the tea leaves T are extended out in the space surrounded by the soft sieve 10 and the soft mesh 50, enabling the teat liquid to flow through the mesh holes 13 of the soft sieve 10 and the mesh holes 23 of the hard sieve 20 or the mesh holes 51 of the soft mesh 50 into the container 1000, finishing the infusion of tea.

[0036] As illustrated in FIG. 6, when using the multipurpose infuser filter strainer 100 to make coffee, put prepared coffee powder C in the space surrounded by the soft sieve 10 and the soft mesh 50, and then put the multipurpose infuser filter strainer 100 in a container 1000, and then pour hot water W in the space surrounded by the soft sieve 10 and the soft mesh 50 to brew the coffee powder C. When brewing the coffee powder C with hot water W, the coffee powder C will be stopped by the soft sieve 10 and the soft mesh 50 in the space surrounded by the soft sieve 10 and the soft mesh 50, and the fluid coffee thus made will flow properly through the mesh holes 13 of the soft sieve 10 and the mesh holes 23 of the hard sieve 20 or the mesh holes 51 of the soft mesh 50 into the container 1000, finishing the preparation of coffee.

[0037] As stated above, when using the multipurpose infuser filter strainer 100 to infuse tea, the tea leaves T can be infused to fully extend out in the space surrounded by the soft sieve 10 and the soft mesh 50, achieving tea infusion. Further, the multipurpose infuser filter strainer 100 can be directly used for making coffee without changing its structure. When brewing coffee, the coffee powder C can be stopped by the soft sieve 10 and the soft mesh 50 in the space surrounded by the soft sieve 10 and the soft mesh 50 so that the fluid coffee thus made does not contain coffee grounds and provides a good taste.

[0038] Referring to FIGS. 1, 5 and 6 again, in order to facilitate using the multipurpose infuser filter strainer 100, the top cap ring 30 provides a positioning flange 31 extended around the periphery thereof for supporting the multipurpose infuser filter strainer 100 in a container 1000.

[0039] In conclusion, the invention provides a multipurpose infuser filter strainer comprising a soft sieve, a hard sieve and a soft mesh. The multipurpose infuser filter strainer is practical for infusing tea as well as for making coffee conveniently and directly without the need of changing its structural arrangement.

[0040] Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
