Description

Technical Field

[0001] The present invention relates to the technical field of beverage filtering devices, and particularly to a coffee filter bag. Background Art

[0002] In modern society, competition is becoming increasingly fierce and workplace pressure is growing day by day. Having a cup of coffee during breaks can boost energy and relieve stress, becoming a beneficial habit. However, to taste delicious coffee, coffee beans need to be ground into coffee powder and then brewed and filtered through a coffee machine before consumption. The grinding and brewing process of traditional coffee is cumbersome and time-consuming, unable to meet the needs of office workers. For the convenience of brewing and carrying, instant coffee has been designed. Since the production of instant coffee requires multiple processes, the beneficial substances and aroma in instant coffee are far less than those of freshly ground coffee. Moreover, if instant coffee is not stirred after brewing, the original flavor of the coffee cannot be fully released and penetrated, affecting the drinking experience. Therefore, brewing packages for instant coffee have been developed to enable users to brew and drink at any time. Currently, many multi-in-one packages and filtered brewing packages that can be directly brewed and drunk are sold on the market for users to choose from.

[0003] Such brewing packages are generally equipped with hanging ear coffee filter bags, which are provided with fixing pieces on both sides of the brewing bag, and movable hanging ears extend from the fixing pieces. The coffee or tea in the hanging ear coffee bag is brewed and filtered by hanging the movable hanging ears on the edge of the container cup mouth. Currently, there are many problems with the existing hanging ear coffee filter bags. For example: (1) The opening of the bag body is small, making it difficult to put coffee into the bag body and inconvenient to brew; (2) The filter bag is only supported by the hanging ears, with poor supporting force and easy to break, resulting in brewing failure. A thicker hanging ear is needed to support the filter bag, which wastes cost and takes up a large space; (3) Most of the bag bodies are V-shaped. When loading coffee powder into the V-shaped hanging ear filter bag, due to the V-shaped bottom of the filter bag, the powder layer thickness at the bottom is large, prone to powder particle accumulation. At the same time, its filtering area is small, making it easy to over-extract coffee and having a greater impact on the coffee flavor; (4) The conical bottom of the hanging ear filter bag extends deep into the container, requiring a deeper cup as the container for brewing coffee, with high requirements for the containing container.

[0004] In summary, the existing hanging ear coffee filter bags generally have problems such as a small opening of the bag body, poor supporting structure, over-extraction, and weak applicability. Summary of the Invention

[0005] The purpose of the present invention is to provide a new type of coffee filter bag, which has a larger opening of the bag body, can accommodate a large amount of coffee powder, and is convenient for brewing. Its supporting structure is stable and has strong supporting force. The bottom is not V-shaped, which can avoid powder particle accumulation and over-extraction, and is applicable to many containers with wide applicability.

[0006] To achieve the above object, the present invention provides a coffee filter bag for use in combination with a container to brew coffee, comprising:

[0007] A bag body, which can selectively present a closed state or an open state, is made of a sheet material with water permeability and filtration properties, has an opening at the top end, a crease at the bottom end, and a protrusion facing the opening direction at the bottom end of the bag body;

[0008] A disc bracket, which is folded outside the bag body and presents a closed state or an open state synchronously with the bag body;

[0009] A connecting part, which at least includes two connecting arms arranged on opposite sides of the bag body, one end of the connecting arm is connected to the bag body, and the other end is connected to the disc bracket,

[0010] The connecting arm is stretched to a certain position to keep the bag body and the disc bracket in an open state, and the disc bracket is lapped on the container and suspends the bag body above the container.

[0011] Compared with the prior art, the bottom end of the bag body of the coffee filter bag of the present invention is provided with a protrusion facing the opening direction, and the thickness of the coffee powder layer at the bottom is lower, which can increase the filtration area to avoid over-extraction, repeated extraction, powder particle blockage, etc. during extraction, and obtain better coffee flavor; the disc bracket and the bag body are connected by the connecting arm, and the disc bracket is lapped on the container, so the disc bracket can be set to a larger size to increase the lapping area, and it can still be stably lapped on the container even during coffee brewing, with a stable support structure and strong supporting force; when the bag body is opened, it is suspended above the container, which is equivalent to being vertically supported on the container. Compared with the traditional hanging ear type, the bottom of the bag body does not need to extend into the middle of the container, and the requirements for the containing container are lower, with strong applicability; at the same time, the bag body is vertically supported above the container, and the bottom end of the bag body is provided with a crease and the top end is provided with an opening, so the opening can be set to a larger size to accommodate a large amount of coffee powder for easy brewing.

[0012] Preferably, the bag body further includes a first sealing edge and a second sealing edge provided at both ends of the crease, and the opening is provided between the other ends of the first sealing edge and the second sealing edge away from the crease.

The first opening edge is connected to the first sealing edge, and the second opening edge is connected to the second sealing edge. The two groups of the first opening edges, the second opening edges and the third opening edges enclose the opening. The opening formed by enclosing the first opening edge, the second opening edge and the third opening edge is larger, which is convenient for coffee brewing.

[0014] Preferably, between the first sealing edge and the disc bracket, and between the second sealing edge and the disc bracket, a foldable member is connected. The foldable member and the bag body are synchronously in a closed state or an open state. When the disc bracket is in an open state, the bag body is supported on the disc bracket by the foldable member. Through the arrangement of the foldable member, the bag body can be stably placed on the container for convenient coffee brewing.

[0015] Preferably, the protrusion is conical or pyramidal, and its height is not greater than 3 / 5 of the height of the bag body. A plurality of bumps are provided on the surface of the protrusion. The bumps can slow down the flow rate of the coffee liquid to avoid the accumulation of coffee powder at the junction of the protrusion and the bottom of the bag body.

[0016] Preferably, the disc bracket is circular, and after folding, two opposite operable notches are formed. The user can open the bag body and the disc bracket by pulling the operable notches, and it has strong operability.

[0017] Preferably, the connecting arm includes a first connecting portion connecting the bag body, a second connecting portion connecting the disc bracket, and a connecting portion connecting the first connecting portion and the second connecting portion. The connecting portion and the second connecting portion are pivotally connected.

[0018] Preferably, a notch is provided on the connecting portion. The second connecting portion can be received in the notch when the bag body is closed. This structure is convenient for processing and can be integrally formed without the need for a third component for reinforcement.

[0030] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings, in which preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] The coffee filter bag of the present invention will be described in detail below with reference to the drawings.

[0032] As Figures 1 to 7 shown, the coffee filter bag 100 is used in combination with a container 200 to brew coffee, and includes a bag body 10, a disc bracket 30 and a connecting portion (not shown in the figure). The bag body 10 can selectively present a closed state or an open state, and is made of a sheet material having water permeability and filtration properties, such as a sheet material of cotton fiber, specifically, non-woven fabric, filter paper, etc. An opening 11 is provided at the top end thereof, a crease 13 is provided at the bottom end, and a protrusion 15 facing the opening 11 is provided at the bottom end of the bag body 10. The disc bracket 30 is folded outside the bag body 10 and presents a closed state or an open state synchronously with the bag body 10. The connecting portion at least includes two connecting arms 50 provided on opposite sides of the bag body 10. One end of the connecting arm 50 is connected to the bag body 10, and the other end is connected to the disc bracket 30. The connecting arm 50 is stretched to a certain position to keep the bag body 10 and the disc bracket in an open state, and the disc bracket 30 is lapped on the container 200 and suspends the bag body 10 above the container 200.

[0033] Furthermore, as Figures 1 to 2, as shown in FIGS. 4 to 6, the bag body 10 further includes a first sealing edge 17 and a second sealing edge 19 provided at both ends of the crease 13. An opening 11 is provided between the other ends of the first sealing edge 17 and the second sealing edge 19 away from the crease 13. There are also two groups of successively connected first opening edges 111, second opening edges 113, and third opening edges 115 between the first sealing edge 17 and the second sealing edge 19. The first opening edge 111 is connected to the first sealing edge 17, and the second opening edge 113 is connected to the second sealing edge 19. The two groups of first opening edges 111, second opening edges 113, and third opening edges 115 enclose the opening 11. The opening formed by enclosing the first opening edge 111, the second opening edge 113, and the third opening edge 115 is relatively large, which is convenient for coffee brewing. Of course, the bag body 10 can also have other structures, such as Figures 3 to 7 shown, the opening of the bag body 10 is circular or quasi-circular, and its opening size is larger. The protrusion 15 is conical (as Figure 3 shown) or pyramidal (as Figures 1 to 2 and Figure 4 shown), and the height is not greater than 3 / 5 of the height of the bag body 10. The surface of the protrusion 15 is provided with a plurality of bumps 151. The setting of the bumps 151 can slow down the flow rate of the coffee liquid to avoid a relatively thick coffee powder layer at the connection between the protrusion 15 and the bottom of the bag body 10. To support the bag body 10, folding members 70 are connected between the first sealing edge 17 and the disc bracket 30, and between the second sealing edge 19 and the disc bracket 30. The folding members 70 and the bag body 10 synchronously present a closed state or an open state. When the disc bracket 30 is in an open state, the bag body 10 is supported on the disc bracket 30 by the folding members 70. Through the setting of the folding members 70, the bag body 10 can be stably placed on the container 200 for convenient coffee brewing. The folding members 70 can be common components on the market, and only need to meet that one end can be fixed on the disc bracket 30, the other end can be fixed on the bag body 10, and the middle part can be movable to synchronously close or open with the bag body 10.

[0034] Continuing as Figures 1 to 7 shown, the connecting arm 50 includes a first connecting portion 51 connecting the bag body 10, a second connecting portion 53 connecting the disc bracket 30, and a connecting portion 55 connecting the first connecting portion 51 and the second connecting portion 53. The connecting portion 55 and the second connecting portion 53 are pivotally connected. The connecting portion 55 is provided with a notch 57. The second connecting portion 53 can be received in the notch 57 when the bag body 10 is closed. The second connecting portion 53 and the connecting portion 55 can be an integral structure, that is, the second connecting portion 53 can be considered as a part cut out from the connecting portion 55. This structure is convenient for processing, and its integral molding does not require a third component for reinforcement. More specifically, the first connecting portion 51 adheres to the bag body 10, and the second connecting portion 53 adheres to or is snap-connected to the disc bracket 30. The snap-connection method can be as Figure 4 and Figure 6As shown, the second connecting portion 53 has a folding portion 59 and is hung on the disc bracket 30 through the folding portion 59. The hanging connection can improve the operation flexibility to facilitate the adjustment of the position of the bag body 10.

[0035] It should be additionally noted that, as Figures 1 to 7 shown, the disc bracket 30 is annular, and after folding, two opposite operable notches 31 are formed. The user can open the bag body 10 and the disc bracket 30 by pulling the operable notches 31, and its operability is strong.

[0036] Compared with the prior art, a protrusion 15 facing the opening 11 direction is provided at the bottom end of the bag body 10 of the coffee filter bag 100 of the present invention. The thickness of the coffee powder layer at the bottom is relatively low, which can increase the filtration area to avoid over-extraction, repeated extraction, powder particle blockage, etc. during extraction, and obtain a better coffee flavor; the disc bracket 30 and the bag body 10 are connected through the connecting arm 50, and the disc bracket 30 is lapped on the container 200. Therefore, the disc bracket 30 can be set to a larger size to increase the lapping area. Even when making coffee, it can still be steadily lapped on the container 200, and its support structure is stable and the supporting force is strong; when the bag body 10 is opened, it is suspended above the container 200, which is equivalent to being vertically supported on the container 200. Compared with the traditional hanging ear type, the bottom of the bag body 10 does not need to extend into the middle of the container 200, and the requirement for the containing container is relatively low, and its applicability is strong; at the same time, the bag body 10 is vertically supported above the container 200, and a crease 13 is provided at the bottom end of the bag body 10 and an opening 11 is provided at the top end. Therefore, the opening 11 can be set to a larger size to accommodate a large amount of coffee powder for easy brewing.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it is not limited to only the embodiments listed. Those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
