DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0024] Referring to FIG. 1, FIG. 1A, and FIG. 2, a hanging device with a disposable beverage filter bag in accordance with a preferred embodiment of the present invention comprises a filter bag 21 and an annular hanging ring 22.

[0025] The filter bag 21 is made of a filter fabric or filter paper to form a flattened single-opening bag. The filter bag 21 has an opening 213 at an upper end thereof and a pair of hanging slits 211 transversely symmetrically located at middle sections of two sides close to the upper end. The hanging slits 211 are half the width of the opening 213.

[0026] The hanging ring 22 is made of a stainless steel wire by winding. A rear section of the hanging ring 22 is a U-shaped holding portion 221. A front section of the hanging ring 22 symmetrically extends forward from the holding portion 221 and has a notch 224 at the frontmost end, and the notch 224 is connected with two ends of a coil spring 225 to form a retractable main frame 222. Middle sections of two sides of the main frame 222 protrude outward to form a pair of hanging portions 223 each having a width slightly greater than that of the hanging slits 211 of the filter bag 21. The caliber of the pair of hanging portions 223 is greater than that of a kettle-shaped container 4 or a cup-shaped container 4, so that the pair of hanging portions 223 can be placed across a top rim 41 of the container 4.

[0027] Through the hanging ring 22, when used, the hanging slit 211 at one side of the filter bag 22 is first hanged on one hanging portion 223, and then the hanging slit 211 at the other side of the filter bag 21 is slightly pulled to hang on the other hanging portion 223, so that the upper section of the filter bag 21 is to form a rectangular-like shape to open the opening 213 for pouring in hot water, and the lower section of the filter bag 21 is uprightly suspended beneath the hanging ring 22 to form a simple assembled filter stand 2 for brewing coffee or tea. This enables the filer bag 21 to trap the coffee grounds or tea leaves and allows the liquid coffee or tea to flow through.

[0028] A rear section of the U-shaped holding portion 221 of the hanging ring 22 is provided with a handle 3. The handle 3 has a forked portion 32 with a clip opening 321 at a lower end thereof and a transverse connecting slot 31 at an upper end thereof for the holding portion 221 to be inserted therethrough. The forked portion 32 with the clip opening 321 is elastic for the top rim 41 of a different thickness. When in use, the forked portion 32 with the clip opening 321 clamps the top rim 41 of the container 4, such that the entire filter stand 2 can be connected above the container 4 and stand stably, as shown in FIG. 2B.

[0029] The handle 3 is movable along the holding portion 221 according to the caliber of the container 4, so that the present invention can be applied to various containers 4 of different calibers.

[0030] As shown in FIG. 2A, the filter bag 21 of the filter stand 2 is placed into the selected container 4, and the enlarged hanging portions 223 of the main frame 222 of the hanging ring 22 are placed across the top rim 41 of the container 4. The bag body 214 of the filter bag 21 won't reach to the bottom of the container, so the filter stand 2 is suspended in the container 4. The user may put coffee powders or tea leaves into the filter bag 21 from the opening 213 and pour in hot water slowly to brew coffee or tea.

[0031] As shown in FIG. 2B, after the coffee and tea has been extracted, the user can hold the holding portion 221 or the handle 3 to lift the entire filter stand 2 to stay above the top rim 41 of the container 4; or the forked portion 32 at the lower end of the handle 3 is used to clamp the top rim 41 of the container 4 for the entire filter stand 2 to stand above the top rim 41 of the container 4. During the lift of the filter stand 2, most of the brew has passed through the bag body 214 to be collected in the container 4. After the filter stand 2 is held or placed above the container 4, the remaining brew continues to pass through the bag body 214 to drip in the container 4.

[0032] As shown in FIG. 2, when the coffee grounds or the tea leaves in the filter bag 21 have no residual water or are in a substantially dry state, the entire filter stand 2 is moved away from the container 4 to complete the brewing. The user can directly take the container 4 for drinking coffee or tea.

[0033] As shown in FIG. 2B, the user may lift the entire filter stand 2, and the forked portion 32 at the lower end of the handle 3 is used to clamp the top rim 41 of the container 4, so that the entire filter stand 2 is placed across the top rim 41 of the container 4. After that, the user puts coffee powders or tea leaves into the filter bag 21 from the opening 213 and pours in hot water slowly to brew coffee or tea.

[0034] During brewing, the brew passes through the bag body 214 of the filter bag 21 to be collected in the container 4. When the coffee grounds or the tea leaves in the filter bag 21 have no residual water or are in a substantially dry state, the entire filter stand 2 is moved away from the container 4 to complete the brewing. The user can directly take the container 4 for drinking coffee or tea.

[0035] According to the aforesaid and the drawings, the container 4 may be a straight glass kettle. The filter bag 21 is made of a fabric or a soft material. After the filter bag 21 is combined with the hanging ring 22 to form the filter stand 2, the suspended bag body 214 can be in any shape or in any size to be placed into different kettles or mugs 4A (as shown in FIG. 2C) or paper drinking cup 4B (as shown in FIG. 2D). As long as the caliber of the container is suitable for the enlarged hanging portions 223 of the main frame 222 of the hanging ring 22 to be placed across the top rim 41, any container can be used. When the user goes out, any container 4 nearby can be used for brewing anytime anywhere. It is very convenient for use.

[0036] As shown in FIG. 3, after brewing, the filter stand 2 (as shown in FIG. 2) is removed. The user pulls the upper edge of the hanging slit 211 at one side of the filter bag 21 outward. Because the main frame 222 is retractable, the hanging slit 211 can be quickly removed from the hanging portion 223 at the same side. The bag body 214 of the filter bag 21 has the weight of the grounds containing water, so the hanging slit 211 at the other side can be released quickly to fall down from the other hanging portion 223, and the hanging ring 22 is restored to the state ready for use, as shown in FIG. 1A.

[0037] As shown in FIG. 3, after brewing, the filter stand 2 (as shown in FIG. 2) is removed. When the user presses the two sides of the main frame 222 inward, the distance between the hanging portions 223 of the two sides of the main frame 222 is shortened because the coil spring 225 is deformed, so that the hanging slits 211 at the two sides of the filter bag 21 lose the support of the hanging portions 223 and the bag body 214 of the filter bag 21 has the weight of the coffee grounds containing water to slide down quickly. The hanging ring 22 is restored to the state ready for use, as shown in FIG. 1A. Thus, it is obvious to demonstrate that the present invention provides excellent convenience in terms of preparations for cleaning and reusing after use, and that the user does not have to touch the filter bag 21 at all. Such a way is clean and hygienic.

[0038] As shown in FIG. 4, the filter bag 21 is in a flattened shape. A plurality of filter bags 21 can be stacked one by one for carrying. Besides, the area of the annular hanging ring 22 is less than that of the filter bag 21, and the annular hanging ring 22 and the handle 3 can be separated from each other. All the filter bags 21, the hanging ring 22, and the handle 3 can be stacked and stored in a bag slightly greater in size than the filter bags 21 for carrying. The user only needs to supply coffee powders, tea leaves, or the like. When going out, any container 4 or cup or paper cup nearby able to accommodate the filter bag 21 can be used for brewing anytime anywhere, and it is convenient for cleaning after brewing to meet the requirements for carrying conveniently.

[0039] According to the aforesaid and the drawings, the filter bag 21 is a straight bag. In order to reduce the area or to provide a centralized filter effect, the filter bag 21 may be a centralized-type filter bag 21A (as shown in FIG. 5A). Lower sections of two sides of the centralized-type filter bag 21 are reduced toward the bottom of the filter bag. The filter bag 21 may be a guide-type filter bag 21B (as shown in FIG. 5B) which has two inward oblique sides. The filter bag 21 may be a centralized-guide-type filter bag 21C (as shown in FIG. 5C). The centralized-guide-type filter bag 21C has two inward oblique sides and lower sections of the two inward oblique sides are reduced toward the bottom of the filter bag. The filter bag can be in any shape, not limited thereto.

[0040] The filter bag 21 according to the aforesaid and the drawings may be formed with a pair of nip portions 212 located above the pair of the hanging slits 211 and extending upward from the middle portion of the opening 213 for the user to nip the filter bag 21 conveniently. It is beneficial to pull the filter bag 21 correctly and to enlarge the hanging slits 211, so that the filter bag 21 can be hanged on the hanging ring 22 quickly.

[0041] Accordingly, the hanging device with the disposable beverage filter bag of the present invention is compact and convenient for assembly and disassembly, and can be stored and carried conveniently for the user to brew coffee or tea anytime anywhere.

[0042] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
